The front end of the upper cigarette turning guide strip 10 is hinged to the upper link of the four-bar linkage mechanism 3 through the first screw, and the height can be adjusted by adjusting the height of the first screw rod, thereby adjusting the height of the front end of the upper smoking turning guide strip 10; Two screw rods 13 are hinged to the lower bracket 6, and the height position of the rear end of the upper cigarette turning guide bar 10 can be adjusted by adjusting the second screw rod 13.

The lower connecting rods of the four-bar linkage mechanism 3 are respectively connected to the middle part of the lower outside turning smoke guide bar 9 and the lower inside turning smoke guide bar 4, and the front ends of the lower outside turning smoke guide bar 9 and the lower inside turning smoke guide bar 4 are all hinged. on the bottom plate.

Both sides of the cigarette pack conveying belt 11 are respectively provided with an outer side baffle 12 and an inner side baffle 5, and the lower bracket 6 is installed on the base plate through the outer side baffle 12 and the inner side baffle 5; the outer side baffle 12 and the inner side baffle 5 Open respectively the through groove that is used for turning over the smoke guide bar 9 on the outside of the bottom and turning over the smoke guide bar 4 on the inside of the bottom, so as to facilitate the horizontal movement of the smoke guide bar 9 on the outside and the smoke guide bar 4 on the inside of the bottom.

Upper bracket 2, bottom outer side turning over smoke guide bar 9, bottom inside side turning over smoke guide bar 4, outer side baffle plate 12 and inside side baffle plate 5 are all fixedly installed on the base plate by L-shaped fixed support 14. The L-shaped fixed support 14 includes a vertical plate and a horizontal plate, wherein the vertical plate is fixed on the side wall of the bottom plate through the support screw 15, and the horizontal plate is connected with the upper bracket 2 and the lower bracket 6 through the fastening screw 16, and the lower side turns the smoke guide Bar 9 and bottom inside turn over smoke guide bar 4 and are hinged on the horizontal plate.

The upper bracket 2 is provided with a locking screw 8 for locking the four-bar linkage mechanism 3 .

The utility model is used when the position of the cable of the cigarette pack changes when the brand of the ZB45 packaging machine is changed. It can realize the purpose of quickly exchanging the position of the cable of the transparent paper of the small package of the ZB45 packaging machine to both sides. The main working process and principle of the utility model are:

The utility model utilizes the part of the space where the original cigarette pack is turned over, and redesigns the turning mechanism, so that the cigarette pack 1 can change direction more easily and conveniently during the turning process. The square upper connecting rod of the four-bar linkage mechanism rod 3 passes through the square holes on the two upper brackets 2; according to the process requirements, the upper cigarette turning guide bar 10 moves inside and outside by pulling the handle 7; the upper connecting rod of the four-bar linkage mechanism 3 Movement, driven by the joint bearing 17, the lower connecting rod and the upper connecting rod move in the opposite direction, thereby driving the lower outer side turning cigarette guide bar 9 and the lower inner side turning cigarette guide bar 4 to move horizontally synchronously, completing the reversing and turning of the cigarette pack Process, after adjusting, lock the four-bar linkage mechanism 3 by the locking screw 8 to complete.

According to the requirements of changing the brand, for example, when producing the "Baisha" or "Liqun" brand, it is necessary to turn the position of the small opening of the cigarette pack to the outside. At this time, loosen the two locking screws 8 on the upper bracket 2, Pull the moving handle 7 inward, and at this time, the four-bar linkage mechanism 3 drives the lower outer cigarette turning guide strip 9 to move outward, and the front end of the upper cigarette turning guide strip 10 moves inward to form a relative movement; at this time, the cigarette is pushed by hand. The pack 1 moves forward, simulating the movement of the cigarette pack 1 on the cigarette pack conveying belt 11, and observing whether the cigarette pack 1 can pass through the angle formed between the lower outer side turning guide strip 9 and the upper part turning cigarette guide strip 10 whether it can smoothly Flip outside, whether the running process is smooth. When the four-bar linkage mechanism 3 is in the original state, that is, when it is rectangular, the upper cigarette guide strip 10 is located in the middle of the lower lateral cigarette guide strip 9 and the lower inner side cigarette guide strip 4, and the upper smoke guide strip 10 is connected to the lower cigarette guide strip 10. The distance between the outer cigarette turning guide strips 9 is smaller than the thickness of the cigarette pack 1; The distance is greater than the thickness of the cigarette pack 1, but there is an angle between the front end of the upper cigarette turning guide strip 10 and the lower outer cigarette turning guide strip 9, and the distance between the two is gradually reduced, so that the cigarette pack 1 turns downwards to the lower outer cigarette guide strip 9 Flip.

At the same time, use the cigarette pack 1 to test and observe whether the height of the rear end of the upper cigarette turning guide strip 10 is lower than the height of the cigarette pressing parts on the back runway. The lower surface of the rear end of the upper cigarette turning guide strip 10 is 1-2mm away from the surface of the cigarette pack. The second screw rod 13 on the lower bracket 6, and there should be no scratches on the cigarette pack 1; use 3-4 packs of cigarettes to carry out the simulation experiment repeatedly, and confirm that the cigarette pack is turned smoothly. After confirming that it is correct, tighten the locking screw 8 and the second screw. Screw 13; so far the adjustment is over; if the production of "Monkey King" or other brands that require the pull wire on the other side, just reverse the adjustment.

The utility model utilizes the principle of the relative movement of the four-bar mechanism to realize the movement of one connecting rod and drive the other connecting rods to carry out relative movement, so that the side of the cigarette pack can be realized in the process of changing the cigarette pack from the vertical transport to the flat transport. The purpose of reversing inside and outside, so as to realize the change of the position of the tie wire, meet the process requirements, and the structure is simple and convenient. When the ZB45 packaging machine quickly changes the brand, the utility model simply moves back and forth and locks, completes the exchange of the position of the small transparent pull wire of the cigarette pack, reduces the adjustment time for the change of the brand, improves the efficiency, and achieves the rapid guidance of the cigarette pack pull wire Purpose. The quick reversing device of the utility model can quickly realize the exchange of the opening positions of the pull belts, thereby broadening the use range of the equipment, solving the problem of production diversity, and providing technical guarantee for the production of the tobacco factory. The utility model also has the following advantages:

1. The four-bar linkage mechanism 3 of the utility model, through the movement of one of the four bars, drives a lower cigarette turning guide strip and an upper cigarette turning guide strip 10 to move relative to each other, forming a space intersection, and completing the turning over of the cigarette pack 1 ; The other bottom turns over the smoke guide bar and the upper part turns over the smoke guide bar 10 to move toward each other, and returns to its original position.

2. The connection between the two lower cigarette turning guide bars and the four-bar linkage mechanism 3 adopts a joint bearing device, which can rotate and have a certain angle to ensure that there is no dead point and interference during the moving process.

3. The shape of the upper cigarette turning guide strip 10 is an arc in the front section, and the rear end is lowered at a certain angle to ensure that the cigarette pack 1 is driven by the cigarette pack conveying belt 11 from a vertical conveying to a lying conveying process to complete the inside and outside of the cigarette pack The commutation is successfully completed.
