Description

Technical Field

[0001] This application relates to the field of pet supplies technology, and more specifically, to a cutting device for producing pet harnesses. Background Technology

[0002] In the pet supplies manufacturing industry, nylon pet leashes are widely used in the production of pet leashes, collars, and other products due to their high strength, good abrasion resistance, and stable weave structure. Traditional cutting processes typically employ cold cutting, where a mechanically pressure-driven cutter cuts the nylon leash to the required length. However, this method causes the nylon leash's weave structure to loosen at the cut edges due to the instantaneous impact of the cutter, resulting in burrs or exposed thread ends. This not only affects the product's appearance but also exacerbates the thread unraveling during use due to friction or pulling, reducing the leash's structural strength and potentially posing safety hazards. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a cutting device for pet strap production, including a worktable. A nylon strap and a limiting mechanism for flattening and limiting the nylon strap are placed on the top of the worktable. The worktable is equipped with a movable blade holder that moves up and down inside it. The top of the movable blade holder is formed with a cutter for cutting the flattened and limited nylon strap. At least one through hole is formed on the side of the cutter, and an electric heating tube for changing the working temperature of the cutter is placed in the through hole. The temperature of the cutter is changed by the electric heating tube, so that the cutter melts and seals the cut edge of the nylon strap simultaneously when cutting it.

[0004] Preferably, the workbench is further provided with a first mounting frame, and the movable tool holder is sleeved on the outside of the first mounting frame. The bottom of the first mounting frame is provided with a first cylinder that drives the movable tool holder and the cutting blade to move outside the first mounting frame.

[0005] Preferably, the side of the cutter is also provided with a temperature sensor for monitoring the temperature of the cutter, and the temperature sensor is located on the side of the through hole.

[0006] Preferably, the limiting mechanism includes a second mounting bracket, and a pressure plate is sleeved on the outside of the second mounting bracket, and a second cylinder is respectively provided on both sides of the top of the second mounting bracket and driven by the pressure plate.

[0007] Preferably, the top of the workbench is further provided with a first guide plate for feeding and guiding the nylon straps, and the first guide plate is located on one side of the limiting mechanism. A first traction cylinder for pulling and feeding the nylon straps is rotatably arranged on the side of the first guide plate. The top of the workbench is also provided with a second guide plate for discharging the nylon straps, and the second guide plate is located on the other side of the limiting mechanism. A second traction cylinder for pulling and discharging the nylon straps is rotatably arranged on the side of the second guide plate.

[0008] Preferably, the top of the workbench is formed with a through-hole relief groove, and a nylon strap covers the top of the relief groove, and a cutter passes through the relief groove to cut the nylon strap.

[0009] In summary, the beneficial effects of this application are as follows:

[0010] When cutting nylon strapping rolls into strips, simply pull the free end of the nylon strapping, then let the strip pass laterally through the limiting mechanism and lay it flat on the top of the worktable. The limiting mechanism then flattens the strip, thus limiting its position. Next, the heating element is activated to heat the cutter. Finally, the operator moves the moving cutter holder, along with the heated cutter, upwards within the worktable until the cutter contacts the bottom of the limited nylon strapping and gradually cuts it. During this cutting process, the heated cutter simultaneously contacts the cut edge, melting and sealing it to prevent problems caused by loose fiber ends at the cut. This not only improves the product's appearance but also ensures the structural strength of the cut nylon strapping. Attached Figure Description

[0020] A cutting device for producing pet leashes, see [link / reference] Figures 1 to 4The system includes a workbench 1, on the top of which is a nylon strap 2 and a limiting mechanism 3 for flattening and limiting the nylon strap 2. The workbench 1 also has a movable blade holder 4 that moves up and down within it. The top of the movable blade holder 4 is formed with a cutter 5 for cutting the flattened and limited nylon strap 2. At least one through hole 6 is formed on the side of the cutter 5, and an electric heating element 7 is placed inside the through hole 6 to change the working temperature of the cutter 5. The electric heating element 7 changes the temperature of the cutter 5, thereby allowing the cutter 5 to cut the nylon strap 2 simultaneously with... The cut edges of the nylon strap 2 are melt-sealed. In this embodiment, the heating element 7 is electrically connected to an external control system (not shown in the figure), and the working temperature of the heating element 7 can be adjusted through the external control system, thereby changing the working temperature of the cutter 5. When it is necessary to cut the rolled nylon strap 2 to a fixed length to obtain 2 strips of nylon strap, it is only necessary to pull the free end of the nylon strap 2, and then let the fixed-length nylon strap 2 pass laterally through the limiting mechanism 3 and then lay it flat on the top of the workbench 1. Then, the limiting mechanism 3 is driven to press the flat strip of nylon strap 2 to the top of the workbench 1. The nylon strap 2 on the top of the workbench 1 is flattened to limit its movement. Then, the heating element 7 is activated to heat the cutter 5. Finally, the operator moves the movable cutter holder 4, along with the heated cutter 5, upwards inside the workbench 1 until the cutter 5 contacts the bottom of the limited nylon strap 2 and gradually cuts it. During this cutting process, the heated cutter 5 simultaneously contacts the cut edge of the nylon strap 2, melting and sealing the edge to prevent the nylon strap from... 2. The series of problems caused by the loose fiber ends at the cut not only improves the appearance of the product, but also ensures the structural strength of the nylon strap 2 after cutting. It effectively solves the technical problem that the nylon strap 2's braided structure is prone to loosening of the fiber ends at the cut due to the instantaneous impact force of the cutter 5 during the cold cutting process, forming burrs or exposed braided threads. This phenomenon not only affects the appearance of the product, but also causes the strap to aggravate the fraying of the threads due to friction or pulling during use, reducing the structural strength of the strap and even causing safety hazards.

[0021] The workbench 1 is also equipped with a first mounting frame 8, and a movable blade holder 4 is sleeved on the outside of the first mounting frame 8. A first cylinder 9 is provided at the bottom of the first mounting frame 8 to drive the movable blade holder 4 and the cutter 5 to move outside the first mounting frame 8. A temperature sensor 10 for monitoring the temperature of the cutter 5 is also provided on the side of the cutter 5, and the temperature sensor 10 is located on the side of the through hole 6. In this embodiment, the temperature sensor is electrically connected to an external control system. By setting the temperature sensor, this embodiment can monitor the working temperature of the cutter 5 in real time and feed the monitored signal back to the external control system, thereby realizing a closed-loop control of "temperature monitoring - signal feedback - power adjustment". When the temperature sensor detects that the temperature of the cutter 5 deviates from the preset temperature according to different specifications of nylon material and weaving density, the system will automatically adjust the temperature. During the cutting process, the control system can automatically adjust the input power of the heating element 7 to avoid carbonization or insufficient melting of the cut surface due to temperature fluctuations. When the nylon strap 2 does not need to be cut, the cutter 5 will be inside the worktable 1, and the first cylinder 9 will not be extended. When the nylon strap 2 needs to be cut, the blade of the cutter 5 will be at the top of the worktable 1, and the first cylinder 9 will be extended. Through the sleeve structure design of the first mounting bracket 8 and the movable blade holder 4, combined with the vertical drive of the first cylinder 9, the lifting and lowering action of the cutter 5 is strictly limited to the vertical direction. This not only effectively avoids the problem of the cutter 5 tilting due to mechanical transmission gaps or uneven loads in traditional cutting devices, but also makes the contact pressure between the cutter 5 and the nylon strap 2 evenly distributed, improving the flatness of the cut surface.

[0022] The limiting mechanism 3 includes a second mounting frame 301, and a pressure plate 302 is sleeved on the outside of the second mounting frame 301. The top two sides of the second mounting frame 301 are respectively provided with second cylinders 303 that are driven and connected to the pressure plate 302. In this embodiment, the pressure plate 302 is driven to press down vertically along the second mounting frame 301 by the second cylinders 303, thereby achieving rigid limiting of the nylon strap 2. When the cutter 5 contacts the strap, the bottom of the pressure plate 302 can provide support for the cutter 5 and form a shearing force with it, which can not only improve the shearing efficiency of the nylon strap 2, but also improve the melting and sealing efficiency of the cut edge of the nylon strap 2.

[0023] The top of the workbench 1 is also provided with a first guide plate 11 for feeding and guiding the nylon straps 2, and the first guide plate 11 is located on one side of the limiting mechanism 3. A first traction cylinder 12 for pulling and feeding the nylon straps 2 is rotatably arranged on the side of the first guide plate 11. The top of the workbench 1 is also provided with a second guide plate 13 for discharging the nylon straps 2, and the second guide plate 13 is located on the other side of the limiting mechanism 3. A second traction cylinder 12 for pulling and discharging the nylon straps 2 is rotatably arranged on the side of the second guide plate 13. In this embodiment, the workbench 1 has two sets of motors (not shown in the figure) and motors (not shown in the figure) at the top of the workbench 1, which drive the first traction cylinder 12 and the second traction cylinder 14 to rotate respectively. The first motor and the second motor drive the first traction cylinder 12 and the second traction cylinder 14 to work, thereby realizing the automatic feeding and unloading of the nylon straps 2. By setting the first guide plate 11 and the second guide plate 13, the nylon straps 2 can maintain axial stability during the feeding and unloading process, which effectively improves the stability of this embodiment.

[0024] The top of the workbench 1 is formed with a through-hole groove 15, and the nylon strap 2 covers the top of the through-hole groove 15. The cutter 5 passes through the through-hole groove 15 to cut the nylon strap 2.

[0025] The above embodiments are merely explanations of this application and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
