Description

Kneading device

technical field

The invention relates to a kneading device, in particular to a kneading device with low noise.

Background technique

Referring to Fig. 1, a kind of massage device 9 previously developed by the applicant, such as the European Union's No. EP20100153605 patent application, includes a U-shaped bracket 91 in cross section, a sheet metal box 92, a longitudinal movement unit 93, a Massage unit 94, and a protection webbing 95. The bracket 91 is vertically arranged in the sheet metal box 92 . The sheet metal box 92 includes a bottom plate 921 for mounting the bracket 91 , a box body 922 extending upward from the bottom plate 921 , and a slot 923 formed on the box body 922 and parallel to the bracket 91 .

The longitudinal movement unit 93 includes a pair of longitudinal movement guide rails 931 installed on the bracket 91 , a longitudinal movement support 932 , and a longitudinal movement motor 933 that drives the longitudinal movement support 932 to longitudinally move up and down along the longitudinal movement guide rails 931 .

The massage unit 94 includes a massage head piece 941 located outside the box body 922, a power shaft 942 eccentrically arranged on the massage head piece 941 and extending through the long slot 923, and a vertically moving bearing seat 932. And the massage motor 943 is located between the vertical movement bearing seat 932 and the bracket 91 and provided for the power shaft 942 . The massage motor 943 can drive the massage head piece 941 to rotate eccentrically around the axis of the power shaft 942 via the power shaft 942 .

The protective webbing 95 is clamped on the box body 922 and covers the long slot 923, and is locked to the vertical movement bearing 932 for the power shaft 942 to pass through, so as to prevent users from inserting their fingers into the long slot. 923 and was pinched.

Although the user can lean against the massage head piece 941 to achieve a massage effect when the massage head piece 941 rotates, the massage device 9 still has the following disadvantages:

1. When the user needs a deeper massage and puts his body weight on the massage head piece 941, since the massage motor 943 is installed between the bracket 91 and the vertical movement bearing 932, the bracket 91 and the vertical movement bearing The distance between the seats 932 increases the distance between the force application point and the force point of the bracket 91 , which easily causes the longitudinal movement seat 932 to shake, thereby generating vibration noise.

2. Because the bracket 91 is installed upright on the bottom plate 921 of the sheet metal box 92, when the user leans against the massage head piece 941, its weight will be transmitted to the bracket 91 via the vertical movement bearing 932 to generate vibration. The vibration generated by the bracket 91 is then transmitted to the box body 922 via the bottom plate 921 , causing the box body 922 to vibrate, thereby causing differential noise between the bracket 91 and the box body 922 .

3. Since the protective webbing 95 is clamped on the box body 922 and locked to the vertical movement bearing seat 932, when the user leans against the massage head piece 941, the vertical movement bearing seat 932 and the box body When the vibrating behavior of 922 is inconsistent, the above-mentioned differential will make the protective webbing 952 vibrate with the vertical movement bearing 93, and then beat the box body 922, causing annoying noise.

4. In order to allow the bracket 91 to have sufficient stability when the user leans against it for massage, the bracket 91 needs to be firmly installed upright on the sheet metal box 92, so that the area of the bottom plate 921 of the sheet metal box 92 cannot be reduced , due to the large area of the bottom plate 921, its thickness must also be increased to provide sufficient stability for the sheet metal box 92, resulting in a bulky and heavy overall volume, which has the disadvantages of being difficult to carry and occupying space on site.

5. Since the massage head piece 941 is directly connected to the power shaft 942, the massage motor 943 and the end of the massage head piece 941 form a structural relationship of a single shaft. When the user applies body weight to the massage head piece 941, it will Directly make the massage head piece 941 swing in the long slot 923 in conjunction with the power shaft 942, and collide with the box body 922 to cause noise.

By the above description, the advantages of the present invention can be summarized as follows:

1. Since the abutment plate 221 of the vertical movement bearing 22 is close to the base plate 11, the distance between the point where the user exerts force on the kneading head 36 and the force point of the vertical movement bearing 22 can be shortened. Even if the user puts the weight of the whole body on the kneading head piece 36, it is not easy to cause the shaking of the kneading head piece 36 and the vertical movement seat 22, thereby achieving the effect of low noise.

2. The present invention utilizes the unequal distances between the longitudinal guide rail 21 and the base plate 11 and the dislocation between the front and rear, and the unequal height of the sliding seat 223 and the up and down dislocation, so that the user presses against the roller. The strength of the head rubbing member 36 relative to the moment generated by the vertical movement seat 22 is mutually pulled and balanced due to the above-mentioned dislocation design, which improves the stability of the longitudinal movement seat 22, thereby reducing the vibration noise caused by instability .

3. The power shaft 32 is shortened by using the support member 34 to slide on the long groove 13 and sleeve on the power shaft 32 and fixed on the longitudinal movement bearing seat 22, and add the extension shaft 351 of the extension member 35 The length of the power shaft 32 can reduce the shaking gap in the long groove 13 and reduce the shaking amplitude of the end of the power shaft 32, which can prevent the power shaft 32 from colliding with the substrate 11, and has the effect of reducing collision noise. The extension tube 352 of the extension piece 35 supports the extension shaft 351 and is respectively fixed on the support piece 34 and the kneading head piece 36, so as to increase the operating stability of the power shaft 32. The extension piece 35 can not only strengthen the mechanical strength of the connection between the kneading head piece 36 and the power shaft 32, increase the service life of the machine, but also reduce the shaking range of the kneading head piece 36, which has the effect of reducing vibration noise. effect.

4. The longitudinal movement unit 2 utilizes the elastic element 28 to be sleeved on the buffer portion 252 and lean against the one of the bearings 24 and the driving portion 251, so as to absorb the linear expansion of the screw 25 due to temperature and manufacturing tolerances , shrink, and then eliminate the vibration gap of the longitudinal movement bearing 22. In addition, the combination of the metal screw 25 and the wear-resistant plastic steel longitudinal movement member 26 can increase the structural precision to reduce the clearance tolerance and reduce the vibration noise. effect.

5. Since the vibration behavior of the vertical movement bearing 22 and the bracket 1 is similar, the protective webbing 42 installed on the longitudinal movement bearing 22 and the bracket 1 is not easy to beat the bracket due to differential motion 1, but has the effect of reducing noise.

6. In the present invention, the duct 6 is extended along the opposite side edges of the base plate 11 and connected to the outer frame 5, which reduces the differential between the base plate 11 and the outer frame 5, and is equipped with shock-absorbing rubber The support pads 7 are respectively arranged at the bottom of the outer frame 5 and the bottom of the conduit 6, so that the force generated by the user against the beating head piece 36 relative to the longitudinal movement seat 22 can be reduced. It can be transmitted to the conduit 6 and the outer frame 5 through the base plate 11 , and finally the shock can be absorbed through the support pad 7 , so as to further increase the overall stability of the machine and reduce frictional noise.

7. The outer frame 5 of the present invention adopts the structural design of the bracket 1 in conjunction with the part, so compared with the known cover-type design, the overall volume can be reduced while maintaining the stability of the bracket 1, which is convenient for transportation , saving space and so on.

8. The present invention utilizes the two ends of the coupling 33 to connect the power shaft 32 and the extension shaft 351 respectively, which can absorb the yaw vibration noise generated by the kneading head 36 after being pushed.

Nine, by virtue of the width of the fixing portion 341 of the support member 34 being smaller than the width of the connecting portion 342, the width of the long groove 13 matched with the fixing portion 341 can be reduced, which not only improves the structural strength of the substrate 11, but also It can prevent users from inserting their fingers into the long groove 13 and improve the safety of use.
