Description

Technical Field

[0001] The utility model relates to the field of automatic processing equipment for winding films, in particular to an automatic tape sticking device for winding films. Background Art

[0002] Plastic winding films, including winding films and bubble films, after being wound and cut off, there is a little film left, and then after it is wound up, it is in a completely loose state. The winding film will hang down and flutter with the wind. Since the winding roller will still roll inertia for a while, the winding film will be loosely wound around the outermost circle. Tape is needed to fix the outside. This process in the prior art is all manual operation after unloading the roll. The tape is used to stick the winding film. Since the height of the material roll itself is about more than three meters, whether it is manually sticking the tape up and down repeatedly or having a special person stick the tape above the frame, it will cause a waste of manpower; there is also manual sticking of the tape during the transportation process after the winding film is unloaded. Since the winding film is not completely wound, it may lead to manual sorting of the surface of the winding film, and sometimes even manually winding several circles, which greatly increases the unnecessary workload. Manual sticking of the tape not only has a large labor intensity, but also is difficult to ensure the consistency and quality of the tape sticking, and easily causes the winding film to become loose during storage and transportation, affecting the overall quality of the product. To solve this problem, an automatic tape sticking device for winding films is provided to replace manual implementation of the tape sticking work for winding films. Summary of the Invention

[0003] The utility model aims at the disadvantages in the prior art and provides an automatic tape sticking device for winding films.

The output shafts on the left and right sides of the speed reducer 44 are respectively connected with a driving rod 47 through a coupling 46.

The gears 45 on both sides are respectively meshed with the racks 411 on the left and right sides of the lifting guide rails 41. The lifting guide rail 41 is slidably arranged on one side of the cross beam 4, so that the lifting guide rail 41 can slide up and down in the axial direction of the lifting guide rail 41 relative to the cross beam 4.

[0025] An adjusting block 53 is arranged at the rear side of the tape - sticking mechanism 5. There are two fixing rods 43. The two fixing rods 43 are parallel to each other. The adjusting block 53 is sleeved on the fixing rod 43 and adjusts its installation position along the fixing rod 43. The lower fixing rod 43 is located in front of the upper fixing rod 43, so that the tape - sticking mechanism 5 extends obliquely downward and forward.

[0026] The tape - sticking mechanism 5 further includes a support frame 54. The adjusting block 53 is fixedly installed at the rear side of the support frame 54. A side plate 55 is further arranged on the side of the support frame 54. A tape reel 56 is arranged on the side plate 55. The tape - sticking roller 51 is installed at the bottom of the side plate 55. The side plate 55 is connected with a tape - sticking power source 57 for driving its up - and - down movement.

[0027] The tape - sticking power source 57 includes a guide rod 571 and a slider 572 slidably arranged on the guide rod 571. The guide rod 571 is fixedly connected with the support frame 54. The slider 572 is fixedly connected with the side plate 55. The cutter cylinder 521 is fixedly installed at the bottom of the support frame 54.

[0028] The frame body 1 includes support feet 11 and a top plate 12. The top plate 12 is fixed at the top of the support feet 11. The front and rear moving guide rails 2 are arranged on the top of the top plate 12. The cross beam 4 is arranged between the two left and right top plates 12.

[0029] The top plate 12 is also provided with a front and rear guiding rack 13. A motor 14 is fixed at the rear side of the cross beam 4. The motor 14 drives the rotation of a connecting rod 15 extending in the left and right directions. The left and right ends of the connecting rod 15 are connected with rolling teeth 16. The rolling teeth 16 are engaged with the front and rear guiding rack 13.

[0030] Working principle:

[0031] A film winding roller winds a film. The film can be a single-layer plastic film or a relatively thick bubble film. When it reaches the preset time or senses that the film has been wound to the preset winding diameter, the winding of the film stops. The cutting knife cuts the film. The way of the cutting knife can be a cutting knife or an up-and-down toothed knife. The previous process of winding the film, the way of the cutting knife, and the way of unloading the film are not limited. The point that the present invention wants to protect is only the mechanism for pasting the film cut by the cutting knife, especially applied to a bubble film machine, because the bubble film has no viscosity at all, and the pasting process after winding is more needed. Before this, the cross beam 4 drives the rotation of the connecting rod 15 extending in the left and right directions through the motor 14. The cooperation between the rolling teeth 16 at the left and right ends of the connecting rod 15 and the front and rear guiding rack 13 realizes the forward and backward movement of the connecting rod 15. The movement of the connecting rod drives the cross beam 14 to move forward and backward. The cross beam 4 reaches the position for pasting by the pasting tape mechanism 5. The angle between the fixing rods 43 can adjust the pasting angle of the pasting tape mechanism 5. The lifting guide rail 41 descends to the corresponding position, and at the same time drives the fixing rods 43 and the pasting mechanism 5 installed thereon to move. The pasting power source 57 drives the pasting roller 51 to descend for pasting. At the same time, the film winding roller rotates by a certain angle. Through the adhesion of the tape to the outer layer of the film, the film winding roller drives the tape reel 56 to feed the tape, which is adhered to the outermost layer of the film. After the adhesion is completed, the cutting knife cylinder 521 drives the cutting knife 52 to move forward and backward to cut the tape at the bottom of the pasting roller 51. Thus, the pasting work is completed. Subsequently, the pasting roller 51 rises, and the pasting tape mechanism 5 rises to give way to the film. After the film is unloaded, a new round of film winding is carried out, and so on in a cycle.

[0032] During the whole process, the equipment triggers the film roll transmission through induction and completes the task in cooperation with the camera automatic charger. The operation involves steps such as pasting the tape, motor driving, film winding, and tape conveying, and accurately and efficiently completes the specified work.
