However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0041] The utility model provides a traction device for sealing strip production.

Adjustment and clamping, and easy to adjust the clamping force; the limit assembly 50 is arranged on the mounting plate 20 behind the two side plates 22, and is used to limit the width direction of the sealing strip to prevent the sealing strip from offsetting when moving forward; the lifting assembly 30 includes a transmission shaft 31 that is laterally and rotatably arranged on the mounting plate 20, and is located on the second side of the door frame 10, the middle part of the transmission shaft 31 is connected to the rotating shaft of the piston rod end of the driving member 32, the driving member 32 is used to drive the transmission shaft 31 to rise and fall, the two gears 33 are respectively arranged at the two ends of the transmission shaft 31, and the two racks 34 are respectively vertically arranged at the two ends of the second side of the door frame 10, and are respectively meshed with the two gears 33.

[0042] The installation plate 20 is raised and lowered on the gantry 10 without affecting the movement of the various parts installed on the installation plate 20. The two conveyor belts 23 rotate in opposite directions, so that the two conveyor belts 23 clamp the sealing strip and convey it forward. When the lifting assembly 30 drives the installation plate 20 and the two conveyor belts 23 to rise and fall, the traction height can be adjusted. This allows the traction device to adapt to different machines to traction and convey the sealing strip.

[0043] In the lifting assembly 30, when the piston rod of the driving member 32 is extended and retracted, the transmission shaft 31 and the mounting plate 20 can be driven to rise and fall, and the two gears 33 on the transmission shaft 31 are meshed with the corresponding racks 34, which will produce rotation. The setting of the two gears 33 and the racks 34 plays a good guiding role in the lifting and lowering of the mounting plate 20. Under the joint action of the first slider 21 and the first slide groove 11, the lifting and lowering of the mounting plate 20 is smooth and easy to adjust.

[0044] As an embodiment, according to the attached Figure 3 It can be seen that the limit assembly 50 includes: a first guide rail 51 is horizontally arranged on the mounting plate 20 behind the side plate 22, and its length direction is perpendicular to the conveying direction of the sealing strip; two second sliders 52 are symmetrically arranged inside the first guide rail 51, and are slidably connected and adapted to the first guide rail 51, and a limit roller 53 is vertically and rotatably arranged above the second slider 52; a screw 54 is horizontally and rotatably arranged in the first guide rail 51, and two threaded sections with opposite rotation directions arranged thereon are respectively threadedly connected to the two second sliders 52.

[0045] The sealing strip passes through between the limiting rollers 53, and the limiting rollers 53 limit and guide the sealing strip. A handle 55 is provided at the end of the screw 54. When the staff turns the handle 55, the two second sliders 52 are threadedly connected with the two threaded sections on the screw 54 with opposite rotation directions, and they will move closer or farther away from each other, thereby adjusting the distance between the two limiting rollers 53 for sealing strips of different widths, ensuring the straight forward movement of the material, and the structure is simple and practical.

[0046] In this embodiment, according to the specification Figure 1 It can be seen that above each second sliding block 52, a plurality of rotatable limiting rollers 53 are arranged along the material traveling direction, and a row of limiting rollers 53 enhances the limiting and guiding effect of the sealing strip.

[0048] Under the drive of the first motor 25, one of the rotating rollers 24 rotates, and the other rotating roller 24 is driven to rotate through the conveyor belt 23. When the side plate 22 is raised or lowered, it can drive the entire side plate 22 to be raised or lowered. Both ends of the rotating roller 24 are provided with side plates 22, and the lifting assembly 30 is connected to the side plate 22 close to the mounting plate 20.

[0049] As an embodiment, according to the attached Figure 4 It can be seen that the adjustment component 40 includes: a second motor 41 is arranged on the top of the mounting plate 20, and a sprocket 42 is arranged at its output end; a chain 43 is wound around the sprocket 42, and its two ends are respectively connected to the two side plates 22; two guide members are respectively connected to the two side plates 22, and are located at both ends of the mounting plate 20, and are used to guide the lifting and lowering of the side plates 22.

[0050] When the thickness of the sealing strip changes, the second motor 41 drives the sprocket 42 to rotate, so that the chain 43 drives one side plate 22 to rise, while the other side plate 22 falls, and moves in opposite directions, so as to facilitate the adjustment of the spacing between the two conveyor belts 23. The two guide components can also guide the lifting and lowering of the side plates 22.

[0051] In this embodiment, according to the specification Figure 4 It can be seen that the guide member includes a second guide rail 44 vertically arranged on the mounting plate 20, and two third sliders 45 arranged on one side of the two side plates 22 are slidably connected and adapted to the second guide rail 44, and the structure is simple.

[0052] In this embodiment, according to the specification Figure 4 It can be seen that the second sliding groove 441 on the second guide rail 44 is a dovetail groove, which can prevent the third sliding block 45 from being separated from the second guide rail 44.

[0053] In this embodiment, the driving member 32 is a hydraulic cylinder, which has stable movement, good load capacity and high reliability.

[0054] In this embodiment, the outer surface of the limiting roller 53 is coated with a rubber coating to increase the friction between the limiting roller 53 and the sealing strip, so as to better guide the sealing strip forward.
