Description

Technical Field

[0001] This utility model relates to the technical field of nylon zipper production equipment, and more specifically, to a webbing cutting device for nylon zipper production. Background Technology

[0002] In the production process of nylon zippers, the webbing cutting process is crucial, as its quality directly affects the overall quality and production efficiency of the zipper. Although there are various webbing cutting machines for nylon zipper production on the market, there are still some areas that need improvement in practical applications.

[0003] Existing patent publication number CN218398253U discloses a zipper webbing cutting device, relating to the field of zipper webbing production technology. It includes a base with two sets of support frames symmetrically mounted on its top. This device solves the problem that current zipper webbing cutting methods rely on manual labor, resulting in low efficiency, increased production costs, and reduced output for enterprises. Furthermore, the cutting process requires manual pulling of the webbing for feeding, which is time-consuming and labor-intensive. In the process of developing this utility model, the inventors discovered the following problems with the existing technology: Some equipment struggles to precisely control the cutting length, resulting in inconsistent webbing lengths after cutting. This not only affects the neatness of the zipper's appearance but may also cause numerous problems in subsequent assembly processes due to size discrepancies, reducing the production pass rate. The problem of webbing shifting during the cutting process is also quite prominent. Due to the lack of effective positioning and fixing devices, the webbing is prone to positional shifts during conveying and cutting, leading to inaccurate cutting and affecting product quality.

[0004] Therefore, a webbing cutting device for nylon zipper production is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a webbing cutting device for nylon zipper production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a webbing cutting device for nylon zipper production, comprising a base plate, a support frame fixedly mounted on the top of the base plate, a transverse cutting groove formed on the upper surface of the support frame, a fixing frame fixedly mounted on the top of the base plate, a motor detachably mounted on one side of the fixing frame, the output end of the motor being connected to a threaded rod, an inner threaded sleeve being threaded onto the outer side of the threaded rod, a lifting pump fixedly mounted at the bottom of the inner threaded sleeve, a blade holder fixedly mounted at the bottom of the lifting pump, a third placement frame fixedly mounted on the top of the base plate, and a zipper roller detachably mounted on the inner wall of the third placement frame.

[0007] Preferably, a bearing is detachably provided at the end of the threaded rod away from the motor, and the bearing is embedded in a preset position on the inner wall of the fixing frame, and the bearing cooperates with the fixing frame.

[0008] Preferably, the bottom of the blade holder is provided with a blade groove, and a cutting blade is movably installed inside the blade groove. The cutting blade is movably installed inside the blade groove, and the cutting blade is perpendicular to the cutting groove on the upper surface of the support frame.

[0009] Preferably, a first placement frame is fixedly installed above the support frame, and fixed cylinders are detachably installed on both sides of the inside of the first placement frame. A buffer spring is installed inside the fixed cylinder, and the buffer spring can extend and retract within the fixed cylinder.

[0010] Preferably, a buffer rod is movably inserted inside the fixed cylinder, one end of the buffer rod is in contact with a buffer spring inside the fixed cylinder, and the other end of the buffer rod away from the buffer spring is fixedly mounted with a compression plate.

[0011] Preferably, a second placement frame is fixedly installed on the upper surface of the support frame by bolts. The second placement frame is located to the right of the first placement frame, and a sliding roller rod is rotatably installed inside the second placement frame.

[0012] Preferably, a positioning frame is fixedly installed above the second placement frame by welding, and a lifting device is detachably provided at the bottom of the positioning frame. A baffle is fixedly installed at the bottom of the lifting device, and the baffle is located directly above the sliding roller rod.

[0013] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this webbing cutting equipment for nylon zipper production uses a cutting blade perpendicular to the cutting groove on the support frame. With the positioning function of the cutting groove, the cutting position can be located, ensuring that the length of the cut webbing is consistent. This effectively solves the problem of low cutting accuracy in existing technologies and improves the product quality of nylon zippers.

[0014] Compared with existing technologies, this webbing cutting equipment for nylon zipper production is less prone to deviation during the webbing conveying process. The extrusion plate on the first placement frame can automatically adjust the pressure according to the webbing thickness under the action of buffer springs and buffer rods, thus stabilizing and fixing the webbing. The baffle on the second placement frame can be adjusted in height via a lifter, further restricting the position of the webbing and effectively preventing it from deviating.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1 As attached Figures 1 to 6 The illustrated webbing cutting device for nylon zipper production includes a base plate 1, a support frame 2 fixedly mounted on the top of the base plate 1, a transverse cutting groove 3 formed on the upper surface of the support frame 2, a fixing frame 4 fixedly mounted on the top of the base plate 1, a motor 5 detachably mounted on one side of the fixing frame 4, the output end of the motor 5 being connected to a threaded rod 6, an inner threaded sleeve 7 being threaded on the outer side of the threaded rod 6, a lifting pump 8 fixedly mounted on the bottom of the inner threaded sleeve 7, a blade holder 9 fixedly mounted on the bottom of the lifting pump 8, a third placement frame 22 fixedly mounted on the top of the base plate 1, and a zipper roller 23 detachably mounted on the inner wall of the third placement frame 22.

[0024] Specifically: First, the motor 5 is installed in a detachable manner, which facilitates subsequent inspection, replacement, and maintenance of the motor 5, enables timely troubleshooting of motor 5 malfunctions, ensures continuous and stable operation of the equipment, and reduces production downtime caused by motor 5 problems. Second, the motor 5 drives the threaded rod 6 to rotate, causing the inner threaded sleeve 7 to move linearly along the threaded rod 6. Combined with the lifting pump 8 to precisely control the position of the blade holder 9, it can achieve high-precision cutting of the webbing by the blade and improve product quality. Third, the transverse cutting groove 3 is opened on the support frame 2 to provide a stable and precise working space for the blade to cut the webbing, ensuring accurate cutting position. Fourth, a third placement frame 22 is set on the base plate 1 and the zipper roller 23 can be detachably installed, which facilitates the replacement of different specifications of zipper roller 23 according to production needs, while ensuring the continuity and stability of webbing supply, improving production efficiency, and meeting the diverse production needs of nylon zippers.

[0025] Example 2 Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details: As a preferred embodiment, a bearing is detachably installed at the end of the threaded rod 6 away from the motor 5. The bearing has excellent wear resistance and low coefficient of friction. The bearing is embedded in a preset position on the inner wall of the fixing frame 4 and cooperates with the fixing frame 4, which greatly facilitates the subsequent inspection, replacement and maintenance of the bearing, effectively extends the service life of the equipment and ensures that the threaded rod 6 can rotate stably for a long time.

[0026] In a preferred embodiment, a blade holder 9 has a blade groove 10 at its bottom, and a cutting blade 11 is movably installed inside the blade groove 10. The inside of the blade groove 10 is smoothed to reduce the friction when the cutting blade 11 moves. The cutting blade 11 is movably installed inside the blade groove 10 and can be flexibly adjusted and replaced according to actual needs. Furthermore, the cutting blade 11 is perpendicular to the cutting groove 3 on the upper surface of the support frame 2. When the equipment is running, the cutting blade 11 can cut into the webbing placed in the cutting groove 3 to achieve efficient and accurate cutting operations.

[0027] In a preferred embodiment, a first placement frame 12 is fixedly installed above the support frame 2 to provide reliable support for subsequent components. Fixed cylinders 13 are detachably installed on both sides of the inside of the first placement frame 12 to facilitate the inspection and replacement of internal components. A buffer spring 14 is installed inside the fixed cylinder 13. The buffer spring 14 is made of high-quality materials and has good elasticity and fatigue resistance. When an external force is applied, the buffer spring 14 can expand and contract within the fixed cylinder 13 to buffer and dampen shocks, protecting the relevant components of the equipment from damage caused by excessive impact.

[0028] In a preferred embodiment, a buffer rod 15 is movably inserted inside the fixed cylinder 13. One end of the buffer rod 15 is in contact with the buffer spring 14 inside the fixed cylinder 13. When subjected to external pressure, the buffer rod 15 compresses the buffer spring 14 inward, using the elastic deformation of the spring to buffer and disperse the force. The other end of the buffer rod 15 away from the buffer spring 14 is fixedly installed with a compression plate 16. The surface of the compression plate 16 is flat and smooth, which can evenly bear and transmit pressure. During the operation of the equipment, it comes into contact with objects such as webbing placed there, playing a stable compression and positioning role.

[0029] In a preferred embodiment, a second placement frame 17 is fixedly installed on the upper surface of the support frame 2 by bolts. The second placement frame 17 is located to the right of the first placement frame 12, which facilitates the overall function and operation of the equipment. A sliding roller rod 18 is rotatably installed inside the second placement frame 17, so that the sliding roller rod 18 can be installed in a rotatable manner. The surface of the sliding roller rod 18 is smooth and it rotates flexibly. When the webbing passes by, it can reduce the friction between the webbing and the webbing, allowing the webbing to move smoothly, thereby ensuring the continuity and stability of the equipment cutting operation.

[0030] In a preferred embodiment, a positioning frame 19 is fixedly installed above the second placement frame 17 by welding. The positioning frame 19 has a stable structure and provides solid support for subsequent components. A lifting device 20 is detachably installed at the bottom of the positioning frame 19 to facilitate inspection, maintenance and replacement of the lifting device 20. A baffle 21 is fixedly installed at the bottom of the lifting device 20. The baffle 21 is located directly above the sliding roller rod 18. When the lifting device 20 drives the baffle 21 to descend, the baffle 21 can block and position the moving webbing on the sliding roller rod 18 to ensure that the webbing is in the correct position when cut.

[0031] In this embodiment, both the substrate 1 and the support frame 2 are commercially available metric equipment that can be directly purchased by those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them and have not made any structural or functional improvements. We will not go into details here.

[0032] The working process of this utility model is as follows: In use, firstly, the zipper roller 23 is detachably installed on the inner wall of the third placement frame 22, and the webbing is pulled out so that it passes through the first placement frame 12. The fixed cylinders 13 on both sides of the first placement frame 12 are equipped with buffer springs 14. A buffer rod 15 is inserted into the fixed cylinder 13 with one end in contact with the buffer spring 14 and the other end fixed with a pressing plate 16. Under the action of the buffer spring 14, the pressing plate 16 automatically adjusts the pressure according to the thickness of the webbing, initially fixing the webbing. Then, the initially fixed webbing continues to be conveyed to the second placement frame 17, passing over the sliding roller rod 18 rotatably installed inside it. A lifting device 20 is detachably installed at the bottom of the positioning frame 19 above the second placement frame 17. The lifting device 20 drives the bottom fixed baffle 21 to descend to a suitable position, performing secondary positioning of the webbing to prevent the webbing from shifting during conveying. Next, the motor 5, which is detachably mounted on one side of the fixed frame 4, is started. The motor 5 drives the threaded rod 6 to rotate. The bearing detachably mounted on the end of the threaded rod 6 away from the motor 5 is embedded in the inner wall of the fixed frame 4 to cooperate with it, ensuring the stable rotation of the threaded rod 6. The rotation of the threaded rod 6 causes the inner threaded sleeve 7, which is fitted with an outer thread, to move horizontally. The inner threaded sleeve 7 drives the bottom-fixed lifting pump 8 to move to a suitable cutting position. Then, the lifting pump 8 is started, which drives the bottom-fixed blade holder 9 to descend. The cutting blade 11, which is movably mounted in the blade groove 10 at the bottom of the blade holder 9, is perpendicular to the cutting groove 3 on the upper surface of the support frame 2. The cutting blade 11 descends into the cutting groove 3 to complete the webbing cutting.

[0033] The above describes the working principle of this webbing cutting equipment for nylon zipper production.
