Description

Technical Field

[0001] This utility model relates to the field of polyvinyl chloride (PVC) tape processing technology, and in particular to a device for cutting PVC tape. Background Technology

[0002] The QJ603A standard, "General Technical Requirements for the Fabrication of Cable Assemblies," stipulates that "the installation of cables and electrical connectors shall be carried out with cable bundles and electrical connectors securely. The metal clamps shall be wrapped with insulating tape or covered with rubber sleeves, with 3mm-10mm of the clamps protruding." The insulating tape wrapped around cable assemblies is mostly made of polyvinyl chloride (PVC) tape, and its width should be cut according to the size of the electrical connector. Currently, the cutting of PVC tape is mainly done manually by workers—that is, workers use tools such as scissors and cutting knives to manually cut the PVC tape into different widths along its extension direction.

[0003] However, manually cutting PVC tape by workers is not only inefficient but also consumes a lot of labor costs. Furthermore, manual cutting of PVC tape is prone to skewed cutting, resulting in substandard appearance of the cable bundle and electrical connectors after installation, and affecting the tensile strength of the end cap.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] Example: The specific embodiments of this utility model are as follows: Figure 1 As shown, a device for cutting polyvinyl chloride (PVC) strip includes a main cabinet 20, which is a horizontally arranged rectangular cube structure with vertical support feet at its four bottom corners. Along the PVC strip conveying path, a strip feeding mechanism, a cutting mechanism, and a strip winding mechanism are sequentially arranged on the upper surface of the main cabinet 20. A controller 21 for controlling the operation of the strip winding mechanism is also provided on the main cabinet 20. In use, the uncut PVC strip is first assembled onto the strip feeding mechanism, and then a worker manually pulls one end of the PVC strip through the cutting mechanism and fixes it onto the strip winding mechanism. Afterwards, the worker can control the entire device to start via the controller 21, thereby automatically cutting the PVC strip.

[0024] This device automatically feeds and rewinds PVC strips through the cooperation of the unloading and winding mechanisms, allowing the PVC strips to be transported and transferred between them. During this transport process, as the PVC strips pass through the cutting mechanism, the cutting mechanism cuts the PVC strips output from the unloading mechanism along the direction of the PVC strips' movement. Therefore, this device can automatically cut the PVC strips, significantly improving production efficiency compared to existing methods that rely entirely on manual labor. Furthermore, the reduced manual intervention also lowers labor costs. Additionally, by minimizing worker handling of the cutting tools, the risk of worker cuts is reduced.

[0025] The specific structure of the tape feeding mechanism in this device is as follows: The tape feeding mechanism includes two uprights 1 positioned opposite each other on both sides of the PVC tape conveying path. These uprights 1 are vertically mounted on the upper surface of the main cabinet 20 using screws and washers at their bottoms. Furthermore, limiting circular plates 2 are detachably and vertically mounted on opposite sides of each of the two uprights 1, with the surfaces of the two limiting circular plates 2 facing each other. These limiting circular plates 2 are fixedly mounted on the uprights 1 and cannot rotate. Simultaneously, a tape feeding shaft 7 is horizontally positioned between the two limiting circular plates 2, with both ends detachably and rotatably connected to the axes of the two limiting circular plates 2. In use, the tape feeding mechanism allows uncut PVC tape to be sleeved around the tape feeding shaft 7. The traction of the PVC tape by the tape winding mechanism, combined with the rotation of the tape feeding shaft 7, enables automatic tape feeding output.

[0026] To enable the detachable positioning and installation of the limiting circular plates 2 on the column 1, locking blocks 3 are fixed at the center of the opposite sides of the two limiting circular plates 2. Correspondingly, the upper end of the column 1 is provided with a mounting groove for the locking blocks 3 to be vertically positioned and engaged. This mounting groove is a U-shaped groove with its opening facing upwards. At the same time, in order to enable the tape-feeding shaft 7 to be rotatably connected to the limiting circular plates 2, bearings 8 are fixed at the center of the opposite sides of the two limiting circular plates 2, and both ends of the tape-feeding shaft 7 are rotatably inserted into the bearings 8.

[0027] In this embodiment, to ensure the smoothness of the PVC tape output by the tape feeding mechanism, multiple tape feeding smoothing rods 4 are provided between the two limiting circular plates 2, arranged around the tape feeding shaft 7 and capable of radial movement along the limiting circular plates 2. The two ends of the tape feeding smoothing rods 4 are perpendicularly connected to the surfaces of the two limiting circular plates 2. As the tape feeding shaft 7 rotates, the PVC tape passes through at least one tape feeding smoothing rod 4. During this process, the surface of the PVC tape comes into frictional contact with the outer surface of the tape feeding smoothing rod 4, thereby ensuring the smoothness of the PVC tape ultimately output by the tape feeding mechanism.

[0028] Meanwhile, to enable the unloading mechanism to accommodate rolls of PVC tape of different diameters, the position of the unloading smoothing rods 4 needs to be adjustable. Therefore, the limiting circular plate 2 has multiple radially extending adjustment ports 6 corresponding to the multiple unloading smoothing rods 4. The ends of the unloading smoothing rods 4 are movably inserted into the adjustment ports 6, and two locking nuts 5, located on both sides of the limiting circular plate 2, are threaded onto the ends of the unloading smoothing rods 4. By loosening / tightening the locking nuts 5 at both ends of each unloading smoothing rod 4, the position of each unloading smoothing rod 4 can be adjusted radially along the limiting circular plate 2, thereby allowing rolls of PVC tape of various specifications to be fitted onto the unloading shaft 7.

[0029] Regarding the cutting mechanism in this device: The cutting mechanism includes a horizontally positioned base plate 9, which is fixed to the upper surface of the main cabinet 20 by screws and washers. A cutting platform block 10, located below the PVC strip, is horizontally fixed to the upper surface of the base plate 9 by screws. Above the cutting platform block 10, a pressure plate 11, located above the PVC strip and capable of horizontal movement in a direction perpendicular to the PVC strip's conveying path, is horizontally positioned. A cutting blade is vertically positioned on the lower surface of the pressure plate 11. Two limiting plates 13, located horizontally on either side of the PVC strip's conveying path, are also horizontally positioned between the cutting platform block 10 and the pressure plate 11. When cutting the PVC strip using this device, the PVC strip, pulled by the winding mechanism, passes horizontally between the cutting platform block 10 and the pressure plate 11, and is cut by the cutting blade during its movement. During this process, the limiting plates 13 can limit and guide the PVC strip on both sides of the PVC strip's conveying path, thereby ensuring the stability of the PVC strip's conveying direction. Meanwhile, the pressure plate 11 can move horizontally along the direction perpendicular to the PVC belt conveying path according to the required segmentation size of the PVC belt, thereby adjusting the position of the cutting blade.

[0030] To facilitate the assembly of the pressure plate 11, the limiting plate 13, and the cutting platform block 10, two sets of screw groups are vertically installed on the pressure plate 11, located on both sides of the PVC belt conveyor path. Each set of connecting screws 14 includes at least two connecting screws 14 arranged sequentially along the PVC belt conveyor path. The connecting screws 14 pass downwards through the pressure plate 11 and the limiting plate 13, and are threadedly connected to the cutting platform block 10. A wing nut 15 located above the pressure plate 11 is also threaded onto the connecting screw 14. Thus, by tightening the wing nut 15, the pressure plate 11, the limiting plate 13, and the cutting platform block 10 can be assembled together in an overlapping manner.

[0031] In this embodiment, to enable the cutting mechanism to pass through PVC belts of various widths, the limiting plate 13 is provided with an adjustment port a that allows the connecting screw 14 to pass through and extends horizontally; and the extension direction of the adjustment port a is perpendicular to the PVC belt conveying path. Thus, by loosening and tightening the wing nut 15, the operator can adjust the distance between the two limiting plates 13, thereby enabling the cutting mechanism to pass through PVC belts of various widths.

[0032] Meanwhile, in order to adjust the position of the cutting blade, the pressure plate 11 is provided with an adjustment port b that extends horizontally through which the connecting screw 14 passes, and the extension direction of the adjustment port b is perpendicular to the PVC belt conveying path. Thus, by loosening or tightening the wing nut 15, the operator can also move the pressure plate 11 horizontally in a direction perpendicular to the PVC belt conveying path, thereby adjusting the position of the cutting blade, and thus enabling the cutting mechanism to adjust the cutting size of the PVC belt.

[0033] In addition, regarding the installation of the cutting blade, the cutting blade adopts a structure with a positioning square handle at the top. Accordingly, in order to facilitate quick and easy installation of the cutting blade, the pressure plate 11 has a cutting blade mounting countersunk hole 12 in the center of its surface for mounting the cutting blade. The shape of the cutting blade mounting countersunk hole 12 is adapted to the positioning square handle. When installing the cutting blade, simply insert the cutting blade vertically downward into the cutting blade mounting countersunk hole 12. At this time, the cutting blade's cutting edge extends downward to below the pressure plate 11, and the cutting blade mounting countersunk hole 12 engages with the positioning square handle to prevent the cutting blade from falling, thereby achieving the installation of the cutting blade.

[0034] In addition, regarding the tape winding mechanism: the tape winding mechanism includes a horizontally arranged optical shaft 18 perpendicular to the PVC tape conveying path. A winding roller 17, rotating synchronously with the optical shaft 18, is sleeved on the optical shaft 18 for winding the PVC tape. Both sides of the optical shaft 18 are equipped with quick-lock heads 19. The quick-lock heads 19 allow operators to easily lock the position of the winding roller 17. Simultaneously, to drive the optical shaft 18, one end of the optical shaft 18 is connected to the output end of the winding motor 16. By driving the optical shaft 18 to rotate through the winding motor 16, the winding roller 17 can be driven to rotate, thereby enabling the winding of the PVC tape.

[0035] In this embodiment, in order to control the operation of the winding motor 16, the controller 21 is provided with a control button for controlling the operation of the winding motor 16.

[0036] The specific working process of this device is as follows: 1. Clamping the PVC tape: First, remove the limiting circular plate 2, the tape feeding shaft 7, and the tape feeding smoothing rod 4 from the column 1 as a whole; then, remove the locking nut 5 on the tape feeding smoothing rod 4 and remove one side of the limiting circular plate 2; after that, adjust the position of the tape feeding smoothing rod 4 and put the rolled PVC tape onto the tape feeding shaft 7; finally, reinstall the limiting circular plate 2 and reassemble it onto the column 1. 2. PVC tape width adjustment: First, pull out a section of PVC tape from the unwinding shaft 7. According to the required width, use a blade or other tools to cut the assembly tape. The cut length should be greater than or equal to "2 times the circumference of the take-up roller 17 + the center distance from the take-up roller 17 to the unwinding shaft 7". Then, unscrew the wing nut 15, remove the pressure plate 11, and adjust the distance between the two limiting plates 13 so that the PVC tape passes between the two limiting plates 13. After that, reassemble the pressure plate 11 and make the cutting edge of the pressure plate 11 pass through the cut on the PVC tape. 3. Fix the PVC strip on the take-up roller 17: Fix the free ends of the cut PVC strip to the take-up roller 17 respectively, and wind it twice until the PVC strip is taut; 4. Connect to power supply: Connect the power plug of the winding motor 16 to a 220V power supply and turn on the power switch on the controller 21. 5. PVC tape cutting: The speed of the winding motor 16 is adjusted by the controller. The PVC tape is pulled by the winding roller 17 to the unwinding shaft 7. The PVC tape passes through the cutting blade on the cutting mechanism and is cut into a fixed width before being coiled onto the winding roller 17.

[0037] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
