Abstract
Description
Technical Field
[0001] This invention relates to the field of cable ties production equipment technology, specifically to an integrated device for bonding and cutting two sections of plastic cable ties. Background Technology
[0002] Strapping tape is made of a mixture of PP and PET plastics. The production process of strapping tape is as follows: plastic granules melted -- pressing -- molding -- cooling -- winding -- packaging -- warehousing.
[0003] Existing plastic strapping is formed and then wound together uniformly, with each roll having a fixed weight. During production, it needs to be cut or glued to ensure the required weight for each roll. When a new strapping is extruded, it needs to be glued to the free end of the already wound strapping to connect it. This step is often done manually, and only one strapping can be glued at a time, which is inefficient. The glued plastic strapping has burrs at the glued joint, affecting its appearance. Therefore, a two-section gluing and cutting device for plastic strapping is proposed. Summary of the Invention
[0004] The purpose of this invention is to solve the problems of slow efficiency and burrs at the glued joints of existing plastic strapping tapes, which are caused by manual cutting or gluing, thus affecting the appearance of the tapes.

[0008] A further technical improvement of the present invention is that: the active roller assembly includes two vertical plates, and two active rollers are rotatably connected to the two active rollers. The two active rollers are stacked and aligned with the two idler rollers on the idler roller assembly. One end of each of the two active rollers is fixedly connected to a gear and they mesh with each other. A motor is provided below the gear to drive its rotation, and the output shaft of the motor is connected to the shaft end of one of the active rollers through a pulley assembly. The motor is mounted below the worktable panel through a motor mounting plate.
[0009] A further technical improvement of the present invention is that: the cutting assembly includes a truss and a linear module, the truss is installed on the table surface of the workbench, the linear module is suspended on the truss, the moving end of the linear module is equipped with a mounting plate, the bottom surface of the mounting plate is equipped with an electric push rod, and the bottom end of the electric push rod is equipped with a connecting plate, and the bottom end of the connecting plate is fixedly connected with a hot melt knife.
[0010] A further technical improvement of the present invention is that: the bonding and polishing assembly includes a second truss and a second linear module. The second truss is installed on the table surface of the workbench, and the second linear module is suspended on the second truss. A second mounting plate is installed on the moving end of the second linear module. A rotary cylinder is installed on the bottom surface of the second mounting plate, and a flat plate is installed on the rotating end of the rotary cylinder. An electric push rod 2 and an electric push rod 3 are respectively installed on both sides of the bottom end of the flat plate.

A third mounting plate is installed on the bottom end of the third electric push rod, and a micro motor is installed on the third mounting plate. The output shaft of the micro motor passes through the third mounting plate and is fixedly connected to a polishing head.
[0011] A further technical improvement of the present invention is as follows: a second boss is installed on the worktable surface directly below the bonding and sanding assembly, and a square hole is opened at the center of the second boss.

[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. The device is equipped with guide wheel assembly, idler roller assembly, and drive roller assembly. Multiple sets of guide wheel assemblies are provided, and the spacing of each set is adjustable to accommodate various widths of strapping tape. The drive roller assembly rotates to drive the strapping tape. When it is necessary to cut the strapping tape, the operation of the three drive roller assemblies is paused. Then, the push rod of the electric push rod one in the cutting assembly extends, allowing the hot melt knife to touch the strapping tape and melt it, thus achieving the cutting function. Furthermore, the hot melt knife can be detached and replaced with different specifications to facilitate the melting of strapping tapes of various widths, making the device widely applicable.
[0015] 2. Equipped with a cutting component and an adhesive grinding component, when the cut strapping reaches the end of the active roller component, the active roller component stops running. After the next new strapping is melted by the cutting component, they are bonded together. During bonding, several sets of strapping are manually positioned and pressed by the U-shaped plate. Then, the adhesive grinding component heat-fuses them separately. The two-section notch alignment fusion results in good fusion effect, beautiful appearance, batch operation, and significantly improves work efficiency.
[0016] 3. The bonding and polishing assembly is equipped with a polishing head. When the rotary cylinder drives the plate to rotate 180°, the polishing head is positioned on the upper surface of the U-shaped plate. The micro motor drives the polishing head to rotate, polishing the surface of the bonded strapping to improve the product's appearance. Furthermore, a point-break component is installed below the second boss. When the strapping needs to be designed as a point-break product, the second lifting cylinder drives the toothed cutting plate to rise and punch point-break holes on the surface of multiple strappings at once. This fast processing speed improves the practicality of the device. Attached Figure Description

Multiple sets of guide wheel assemblies 3 are provided, and their spacing can be adjusted to accommodate various widths of strapping tape. The active roller assembly 5 rotates to drive the strapping tape. When it is necessary to cut the strapping tape, the operation of the three active roller assemblies 5 is paused. Then, the push rod of the electric push rod 64 in the cutting assembly 6 extends, causing the hot melt knife 66 to touch the strapping tape and melt it, thus achieving the cutting function. Furthermore, the hot melt knife 66 can be detached and replaced with different specifications, which is convenient for melting strapping tapes of various widths, making the device widely applicable.
[0044] The cutting assembly 6 includes a truss 61 and a linear module 62. The truss 61 is installed on the table surface of the workbench 1. The linear module 62 is suspended on the truss 61.

The bottom end of the third electric push rod 87 is equipped with a third mounting plate 810, and a micro motor 811 is installed on the third mounting plate 810. The output shaft of the micro motor 811 passes through the third mounting plate 810 and is fixedly connected to a polishing head 812.
[0046] By adopting the above technical solution: the bonding and polishing assembly 8 is equipped with a polishing head 812. When the rotary cylinder 84 drives the plate 85 to rotate 180°, the polishing head 812 is located on the upper surface of the U-shaped plate 12. The micro motor 811 drives the polishing head 812 to rotate, polishing the surface of the bonded strapping, improving the product's aesthetics. Furthermore, a point-break assembly 13 is provided below the boss 2 9. When the strapping needs to be set as a point-break product, the lifting cylinder 2 132 drives the toothed cutting plate 133 to rise and punch point-break holes on the surface of multiple sets of strapping at once. The processing speed is fast, improving the practicality of the device.
[0047] A boss 2 9 is installed on the worktable 1 directly below the bonding and sanding component 8, and a square hole 10 is opened at the center of the boss 2 9. The square hole 10 passes through the worktable 1 and the table panel of the worktable 1.

[0048] The point-breaking assembly 13 includes an L-shaped plate 131, which is fixed to the lower end of the workbench panel 1. A lifting cylinder 132 is installed on the side wall of the L-shaped plate 131, and a toothed cutting edge 133 is fixedly connected to the piston end of the lifting cylinder 132. The thickness of the toothed cutting edge 133 is less than the width of the square hole 10, and the toothed cutting edge 133 can pass through the square hole 10. The cutting edge of the toothed cutting edge 133 is set as serrated.
[0049] By adopting the above technical solution: the bonding and polishing assembly 8 is equipped with a polishing head 812. When the rotary cylinder 84 drives the plate 85 to rotate 180°, the polishing head 812 is located on the upper surface of the U-shaped plate 12. The micro motor 811 drives the polishing head 812 to rotate, polishing the surface of the bonded strapping, improving the product's aesthetics. Furthermore, a point-break assembly 13 is provided below the boss 2 9. When the strapping needs to be set as a point-break product, the lifting cylinder 2 132 drives the toothed cutting plate 133 to rise and punch point-break holes on the surface of multiple sets of strapping at once. The processing speed is fast, improving the practicality of the device.
[0050] In use, the spacing between the multiple sets of guide wheel assemblies 3 is adjusted to accommodate the current width of the strapping. Then, the strapping is sequentially threaded through the idler roller assembly 4 and the active roller assembly 5. The motor 54 in the active roller assembly 5 drives the pulley assembly 55 to rotate, and the pulley assembly 55 drives the active roller 52 to rotate. Two gears 53 drive the two active rollers 52 to rotate in opposite directions, so that the strapping can be transported forward.

Then, the push rod of the electric push rod 64 in the cutting assembly 6 extends so that the hot melt knife 66 touches the strapping and melts it, thus achieving the cutting function. Furthermore, the hot melt knife 66 can be detached and replaced with different specifications to facilitate the melting of strapping of various widths.
[0051] When the cut strapping reaches the end of the active roller assembly 5, the active roller assembly 5 stops running. After the next new strapping is melted by the cutting assembly 6, they are bonded together. During bonding, several sets of strapping are manually positioned and pressed by the U-shaped plate 12. Then, the bonding and polishing assembly 8 heat-fuses them separately, and the two sections are notched and aligned.
[0052] When the rotary cylinder 84 drives the plate 85 to rotate 180°, the grinding head 812 is located on the upper surface of the spiral plate 12. The micro motor 811 drives the grinding head 812 to rotate, grinding the surface of the bonded strapping to improve the product's aesthetics. Furthermore, a point-break component 13 is provided below the boss 2 9. When the strapping needs to be set as a point-break product, the lifting cylinder 2 132 drives the toothed cutting plate 133 to rise and pass through the square hole 10, punching point-break holes on the surface of multiple sets of strapping at once.
