DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. 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.

[0039] The utility model provides a reeling device for processing the framework of automobile sealing strips. Figure 1 -Attached Figure 5 It can be seen that the unwinding disc 11 arranged on the first bracket 10 rotates under the drive of the motor 12, and the motor 12 is electrically connected to the controller; the swing mechanism 20 is arranged above the first bracket 10 on one side of the unwinding disc 11, and the material on the unwinding disc 11 passes through the swing mechanism 20, and the swing mechanism 20 is used to adjust the tension of the material; the swing mechanism 20 includes a rotating shaft 21 horizontally and rotatably arranged above the first bracket 10 on one side of the unwinding disc 11, and the length direction of the rotating shaft 21 is parallel to the rotation direction of the unwinding disc 11. In the tangential direction of rotation, the swing rod 22 is spliced ​​into an L shape by a long rod and a short rod, and is arranged above one side of the unwinding disk 11, and the connecting block 23 arranged at the upper end of the long rod is connected to the first end of the rotating shaft 21. The material passes through the splicing of the swing rod 22. When the speed of the unwinding disk 11 and the winding disk is inconsistent, the swing rod 22 swings under the pull of the material. The control component 24 is connected to the other end of the rotating shaft 21 and is electrically connected to the controller. The control component 24 is used to detect the rotation of the rotating shaft 21 and control the speed of the motor 12.

[0040] The motor 12 drives the unwinding disk 11 to rotate and unwind the material. The material first passes through the swing mechanism 20, and then enters the next processing equipment for processing. The material is then reeled by the rotation of the reel. Since the unwinding and rewinding speeds are prone to mismatch in continuous production, the material is overstretched or relaxed. The swing mechanism 20 controls the unwinding speed of the material during the unwinding and rewinding process to maintain uniform tension of the material, ensure stable quality of the finished product, and adapt to changes in production speed to reduce material waste.

[0041] The material passes through the swing rod 22 in the swing mechanism 20. When the rotation speeds of the unwinding reel 11 and the winding reel are inconsistent, the traction force of the material changes, causing the swing rod 22 to swing. When the swing rod 22 swings, the mounting plate 241 is driven to rotate through the action of the rotating shaft 21, and the control component 24 plays a role, adjusting the speed of the motor 12 to change the unwinding speed to adjust the tension of the material, ensuring that the tension of the material is uniform during the unwinding process, avoiding excessive stretching or relaxation, improving the quality stability of the finished product, and at the same time improving production efficiency. The automatic adjustment of the speed of the motor 12 reduces dependence on manual labor and reduces labor intensity. Specifically, the swing amplitude of the swing rod 22 during operation is between 15° and 45°.

[0042] As an embodiment, according to the attached Figure 2 -Attached Figure 3 It can be seen that the control component 24 includes a mounting disk 241, which is arranged at the second end of the rotating shaft 21. A sensor 242 is arranged on the first bracket 10 on one side of the mounting disk 241. The detection end of the sensor 242 is connected to the nylon wire 243 wound on the mounting disk 241. When the mounting disk 241 rotates, the nylon wire 243 is tightened or relaxed, and the sensor 242 is electrically connected to the controller.

[0043] Since the nylon line 243 has strong toughness and strength, it will not break when being pulled.

[0044] The sensor 242 senses the change of tension force through the nylon line 243 and converts the force into an electrical signal. The sensor 242 captures the rotation change of the swing rod 22 and adjusts the speed of the motor 12 through the controller. The force change captured by the sensor 242 reflects the rotation state of the mounting plate 241, and indirectly indicates the tension state of the frame material.

[0045] When the speed of the winding reel is greater than that of the unwinding reel 11, the material tension force becomes greater, the swing rod 22 is pulled inward, driving the mounting disk 241 to rotate clockwise, the nylon line 243 is tightened, and the speed of the adjustment motor 12 increases; when the speed of the winding reel is less than that of the unwinding reel 11, the material tension force becomes smaller, the swing rod 22 is pulled outward, driving the mounting disk 241 to rotate counterclockwise, the nylon line 243 is relaxed, and the speed of the adjustment motor 12 decreases.

[0046] As an embodiment, according to the attached Figure 1 -Attached Figure 4 It can be seen that a second bracket 13 is also provided on one side of the unwinding disk 11. The first bracket 10 and the second bracket 13 can rotate around the unwinding disk 11 for position adjustment. The material passes into the guide assembly 30 provided on the second bracket 13 to guide the material into subsequent equipment.

[0047] The guide assembly 30 provided on the second bracket 13 can accurately guide the material into the next processing equipment, reduce dislocation or distortion, and maintain processing continuity. The first bracket 10 and the second bracket 13 can rotate relative to the unwinding disk 11 and adjust the position, and can adjust the best feeding angle according to the material size, shape or production requirements, and also facilitate the installation of the unwinding disk 11.

[0048] In this embodiment, according to the specification Figure 4 -Attached Figure 5 It can be seen that the guide assembly 30 includes: a guide wheel 31 is horizontally and rotatably arranged above the second bracket 13 through a mounting frame 32, and baffles 33 are respectively sleeved on both sides of the guide wheel 31. Each baffle 33 can move horizontally along the length direction of the guide wheel 31 under the action of an adjusting member 34; a lifting rod 35 is arranged vertically below the mounting frame 32 and is slidably connected to a square first guide sleeve 36 arranged on the second bracket 13 up and down, and is fixed by a fixing member 37.

[0049] The guide wheel 31 is used to assist the material to pass smoothly and reduce friction and obstruction. The baffles 33 installed on both sides of the guide wheel 31 are moved along the length direction of the guide wheel 31 through the adjustment member 34 and can be adjusted as needed. The lifting rod 35 can be adjusted up and down and fixed in position by the fixing member 37. The height of the lifting rod 35 is adjustable to ensure accurate docking when entering the subsequent processing equipment.

[0050] In this embodiment, according to the specification Figure 4 It can be seen that the fixing member 37 includes: a pull rod 371 is horizontally arranged, and its first end extends into the first guide sleeve 36, the extrusion plate 372 is arranged to abut against the corresponding side of the lifting rod 35, the second end of the pull rod 371 extends out of the first guide sleeve 36, and is provided with a handle 373; the first spring 374 is sleeved on the pull rod 371 between the handle 373 and the first guide sleeve 36.

[0051] When the height of the lifting rod 35 needs to be adjusted, the squeeze plate 372 is separated from the lifting rod 35 by pulling the handle 373, and the lifting rod 35 can be driven to move in the guide sleeve. The first spring 374 provides a restoring force. When the handle 373 is released, the pull rod 371 returns to the initial position, and the lifting rod 35 and the squeeze plate 372 are fixed by the elastic force of the first spring 374, so as to achieve a stable fixing effect.

[0052] In this embodiment, according to the specification Figure 5 It can be seen that the adjustment component 34 includes: two guide columns 341 are horizontally and symmetrically arranged on the outside of the baffle 33, and are slidably connected and adapted to two second guide sleeves 342 arranged on one side of the corresponding mounting frame 32; two second springs 343 are respectively sleeved on the two second guide sleeves 342 between the baffle 33 and the mounting frame 32.

[0053] The two guide posts 341 are connected to the second guide sleeve 342 by sliding, which guides the horizontal movement of the baffle 33 and ensures the stability during adjustment. The second spring 343 enables the baffle 33 to be adjusted adaptively when the material moves forward.

[0054] In this embodiment, according to the specification Figure 2 It can be seen that two rollers 221 are respectively provided at the joints of the long rod and the short rod, and the material is connected to the two rollers 221 by rolling.

[0055] When the material passes through the swing rod 22, it contacts the swing rod 221, which reduces the friction between the material and the rod, protects the material from damage, reduces resistance, and ensures smooth passage of the material.

[0056] In this embodiment, according to the specification Figure 2 It can be seen that a screw rod 41 is horizontally arranged on the first bracket 10 below the rotating shaft 21 and fixed by a bolt 42. The length direction of the screw rod 41 is perpendicular to the length direction of the rotating shaft 21, and a blocking member 43 is arranged at one end of the screw rod 41 close to the unwinding disk 11, which is used to limit the swing rod 22.

[0057] The staff can adjust the position of the blocking member 43 through the bolt 42, and setting the blocking member 43 can prevent damage caused by excessive external force or improper operation, keep the swing rod 22 within a safe and controllable movement range, ensure that the nylon rope will not break, and ensure the stable operation of the device.

[0058] In this embodiment, the side surfaces corresponding to the squeezing plate 372 and the lifting rod 35 are coated with a rubber coating, so as to increase the friction between the squeezing plate 372 and the lifting rod 35 and ensure the fixing effect of the lifting rod 35.
