Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing technology, and in particular to a heat shrink tubing pulling device. Background Technology

[0002] Heat shrink tubing is a specially designed heat shrink sleeve made of polyolefin material. The outer layer is made of high-quality, soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, waterproof sealing and high adhesion.

[0003] Thermal shrinkage refers to the shrinkage behavior of polymer materials when heated, with a shrinkage rate typically around 30%. This thermal shrinkage phenomenon is fundamentally different from the thermal expansion and contraction of some small molecules, which mainly refers to the abnormal thermal expansion and contraction behavior of substances caused by intermolecular hydrogen bonds and other factors.

[0004] During the production process, heat shrink tubing with elasticity needs to be stretched to facilitate winding and packaging. However, during use, the position of the pulling wheel is fixed, resulting in insufficient winding force for tubing with different heat shrinking forces. After winding, it is relatively loose and easy to unwind. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems and shortcomings by proposing a heat shrink tubing pulling device: the screw rod two drives the lower pressure wheel to move up and down through the threaded block two, increasing or decreasing the pulling force on the heat shrink tubing, thereby improving the tightness of the wound heat shrink tubing, facilitating the adjustment of the pulling force, and solving the problem of loose winding caused by insufficient pulling force.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heat shrink tubing pulling device includes a worktable. An unwinding assembly and a rewinding assembly are respectively installed at both ends of the top outer wall of the worktable. A pressure hole is opened at the center of the worktable, and a pressure-applying structure is provided on the outer wall of the worktable at the pressure hole. The unwinding assembly includes a first upright rod, an adjusting groove on one side of the outer wall of the first upright rod, a first lead screw rotatably connected to the center of the adjusting groove, a first threaded block threadedly connected to the outer wall of the first lead screw, and a cylinder welded to the outer wall of one side of the first threaded block. The pressure-applying structure includes a pressure rod welded to the center of the pressure hole on the worktable, a pressure groove on one side of the outer wall of the pressure rod, a second lead screw rotatably connected to the center of the pressure groove, and a second threaded block threadedly connected to the outer wall of the second lead screw.

[0008] Preferably, a screw rod is welded to the center of one side of the outer wall of the cylinder, and a limit plate is threadedly connected to the outer wall of the screw rod.

[0010] Preferably, a sliding plate is welded to both sides of the outer wall of one end of the threaded block, and a groove is opened on the outer wall of the upright at the sliding plate, and the outer wall of one side of the sliding plate is slidably connected to the groove and the outer wall of the upright.

[0011] Preferably, a sliding plate is installed on one side of the outer wall of the threaded block two, and the outer wall of the sliding plate is slidably connected to the outer wall of the pressure rod. A lower pressure wheel is rotatably connected to one end of the outer wall of the threaded block two, and a motor two is installed on the top outer wall of the pressure rod. The output shaft of the motor two is connected to the top of the lead screw two.

[0012] Preferably, the winding assembly includes a second upright post, a third motor mounted on the outer wall of one side of the second upright post, a winding rod connected to the output shaft of the third motor, a threaded groove formed on the outer wall of one end of the winding rod, and a clamping plate threadedly connected to the threaded groove.

[0013] Preferably, both the winding rod and the screw rod have pin holes on their outer walls at one end, and pins are inserted into the pin holes.

[0014] Preferably, the three motors, the second motor, and the first motor are connected to a switch via wires, and the switch is connected to a power source via wires.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The second screw drives the lower pressure roller to move up and down through the second threaded block, increasing or decreasing the pulling force on the heat shrink tubing, thereby improving the tightness of the wound heat shrink tubing, making it easier to adjust the pulling force and making it easier to pull.

[0017] 2. The motor drives the cylinder to move up and down through the threaded block. The distance between the cylinder and the worktable is adjusted by the up and down movement of the cylinder.

[0029] Example 2:

[0030] Reference Figure 1-3The unwinding assembly 4 includes a pole 6, an adjustment groove 7 formed on one side of the outer wall of the pole 6, a lead screw 8 rotatably connected to the center of the adjustment groove 7, a threaded block 9 threadedly connected to the outer wall of the lead screw 8, and a cylinder 13 welded to one side of the outer wall of the threaded block 9.

[0031] A screw rod 14 is welded to the center of one side of the outer wall of the cylinder 13, and a limit plate 15 is threadedly connected to the outer wall of the screw rod 14. The limit plate 15, together with the screw rod 14, facilitates the restriction of rolls of different sizes on the outer wall of the cylinder 13, which is convenient for assisting in winding.

[0032] A motor 12 is installed on the outer wall of the top of the upright 6, and the output shaft of the motor 12 is connected to the top of the lead screw 8. The outer wall of the threaded block 9 is slidably connected to the inner wall of the adjusting groove 7. After the motor 12 is started, it drives the lead screw 8 to rotate.

The pin is then inserted into the pin hole 16 to restrict the limiting plate 15 and clamping plate 28. One end of the heat shrink tubing is then fixed to the outer wall of winding rod 25 after passing over the outer wall of pressure roller 23. Then, motor 3 26 is started to drive winding rod 25 to rotate, and winding rod 25 pulls the heat shrink tubing to wind it up. Motor 20 is started to drive lead screw 2 19 to rotate. Lead screw 2 19 drives pressure roller 23 to move up and down through threaded block 21, increasing or decreasing the pulling force on the heat shrink tubing, so that the heat shrink tubing is wound up. The heat shrink tubing has improved tightness, making it easier to adjust the pulling force and facilitate pulling. After the motor 12 starts, it drives the lead screw 8 to rotate. After the lead screw 8 rotates, it drives the cylinder 13 to move up and down through the threaded block 9. The up and down movement of the cylinder 13 adjusts the distance between it and the worktable 1, making it easy to adjust. The limit plate 15, together with the screw rod 14, makes it easy to restrict rolls of different sizes to the outer wall of the cylinder 13, which facilitates winding.
