Description

Technical Field

[0001] This utility model relates to the field of nylon elastic knitted fabrics, specifically a pre-relaxation device for nylon elastic knitted fabrics. Background Technology

[0002] Nylon stretch knitted fabric is a type of fabric made primarily of nylon using a knitting process. It is characterized by its good elasticity and comfort, lightweight texture, wear resistance, and strong tensile strength. Due to the use of nylon fibers, this fabric typically has good durability and UV resistance, and is therefore widely used in sportswear, casual wear, underwear, swimwear, and many other fields.

[0003] The pre-relaxation treatment of nylon elastic knitted fabric is to eliminate the internal stress generated in the fabric during weaving and dyeing, thereby avoiding problems such as deformation, shrinkage or dimensional instability during subsequent use. In actual use, the existing pre-relaxation device is installed on one side of the sliding plate by the operator through a clamping mechanism, and then stretched with the heat treatment component. After the pre-relaxation is completed, the operator disassembles the clamping mechanism and removes the device. This process is too wasteful of manpower and resources and reduces the overall processing efficiency.

[0004] In summary, existing pre-relaxation treatment devices require manual disassembly and reassembly of the nylon elastic knitted fabric during actual use, resulting in excessive waste of manpower and resources and reduced overall processing efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a pre-relaxation device for nylon elastic knitted fabrics to solve the technical problem that manual disassembly and assembly of nylon elastic knitted fabrics leads to excessive waste of manpower and resources in the processing process and reduces the overall processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-relaxation device for nylon elastic knitted fabric, comprising a worktable and a heat treatment assembly. The heat treatment assembly has an array of uniformly arranged arrays on the top of the worktable. A sliding plate is symmetrically slidably arranged on the top of the worktable, and an inner groove is formed on the inner wall of each sliding plate. An upper clamping plate is elastically arranged on the top of the inner groove, and a lower clamping plate is slidably arranged on its bottom. A guide post is connected to the bottom end of the lower clamping plate through the sliding plate. An irregularly shaped sliding groove is formed on the top of the worktable for the guide post to slide.

[0007] By adopting the above technical solution, the upper clamping plate, in conjunction with the lower clamping plate, pre-clamps the nylon elastic knitted fabric under its elastic action. Then, the sliding plate slides to both sides, pulling the nylon elastic knitted fabric taut. During this process, the lower clamping plate slides upward through the cooperation of the guide post and the irregular groove, thereby completing the limiting clamping work of the nylon elastic knitted fabric. It is then pre-relaxed in conjunction with the heat treatment components on the worktable. During the subsequent reset process, the lower clamping plate resets along with the guide post, making it easy for the staff to directly remove the nylon elastic knitted fabric from the sliding plate. This process reduces the overall clamping burden and improves the efficiency of the pre-relaxation treatment.

[0008] The present invention is further configured such that a placement plate is provided at the top center of the workbench, and the placement plate itself is recessed. The placement plate is sealed at its center and has a series of through holes that diffuse outward from the inside.

[0009] Preferably, during the stretching process, the plate supports the middle position of the nylon elastic knitted fabric to ensure its overall flatness and increase the contact area with the heat treatment component. When the heat treatment component blows out hot air, the hot air diffuses to the outside through the middle sealing setting and is discharged to the bottom of the nylon elastic knitted fabric through its through holes, which further improves the working efficiency of the heat treatment component.

[0010] The present invention is further configured such that electric drive components are provided on both sides of the irregularly shaped slide groove at the top of the worktable, and the electric drive components are used to drive the sliding plate to slide on the top of the worktable.

[0011] Preferably, the electric drive component allows operators to easily control the sliding distance of the sliding plate and the pre-relaxation time, further ensuring that the device is suitable for different nylon elastic knitted fabrics.

[0012] The present invention is further configured such that a reset spring is wrapped around the outer wall of the guide post, and the other end of the reset spring is located inside the sliding plate.

[0013] Preferably, when the guide post slides upward under the action of the irregular groove, it will squeeze the return spring at the top. During this process, the return spring itself is in a compressed state. When the sliding plate is reset, the guide post drives the lower clamping plate to slide downward under the reset action of the return spring.

[0014] The present invention is further provided with a protective sleeve on the inner wall of the upper clamping plate and the lower clamping plate, and the protective sleeve itself is detachable.

[0015] Preferably, the protective sleeve prevents the upper and lower clamps from directly contacting the nylon elastic knitted fabric, further improving the pre-relaxation treatment effect of the nylon elastic knitted fabric.

[0016] The present invention is further configured such that an array of support legs are symmetrically arranged at the bottom of the workbench.

[0017] Preferably, the support legs are designed so that the top of the workbench is away from the opposite side, effectively reducing the impact of dirt and impurities from the ground on the nylon elastic knitted fabric.

[0018] The present invention is further configured such that the inner wall of the irregular shaped groove is smooth, and an arc-shaped end face is provided at the bottom of the guide post.

[0019] Preferably, the smooth shape reduces the sliding friction between the guide post and the irregular groove, while the arc-shaped end face at the bottom of the guide post facilitates the sliding plate to slide on the top of the worktable, further improving the overall sliding stability of the sliding plate.

[0020] The present invention is further configured such that the top of the placement plate is horizontally positioned and a smooth surface is provided on its top.

[0021] Preferably, the top of the placement plate facilitates support for the nylon elastic knitted fabric in the pre-relaxed state, preventing the nylon elastic knitted fabric from concave and further improving the overall treatment effect of the nylon elastic knitted fabric.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model features symmetrically arranged sliding plates on a worktable. The operator places both ends of the nylon elastic knitted fabric to be processed into the inner grooves of the sliding plates. The upper clamping plate, in conjunction with the lower clamping plate, pre-clamps the fabric. The sliding plates then slide to both sides, tightening the nylon elastic knitted fabric. During this process, the lower clamping plate slides upwards through the cooperation of guide posts and irregularly shaped grooves, thus completing the clamping and positioning of the nylon elastic knitted fabric. This is followed by pre-relaxation treatment using the heat treatment components on the worktable. During the subsequent reset process, the lower clamping plate resets via the guide posts, allowing the operator to easily remove the nylon elastic knitted fabric from the sliding plates. This process reduces the overall clamping burden and improves the efficiency of the pre-relaxation treatment.

[0024] 2. This utility model features a placement plate positioned in the middle of the workbench. During the stretching process, the placement plate supports the middle of the nylon elastic knitted fabric, ensuring its overall flatness and increasing the contact area with the heat treatment components. The placement plate itself is concave and sealed in the middle, with a series of through holes extending outwards. When the heat treatment components blow hot air, the sealed middle section allows the hot air to diffuse outwards and dissipate through the through holes to the bottom of the nylon elastic knitted fabric, further improving the working efficiency of the heat treatment components.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] First embodiment:

[0035] Please see Figures 1-5The device for pre-relaxing nylon elastic knitted fabric includes a worktable 1, a heat treatment assembly 7, a limiting mechanism, a sliding mechanism, and a clamping mechanism. Sliding plates 3 are symmetrically slidably arranged on the top of the worktable 1, and each sliding plate 3 has an inner groove 6 on its inner wall. An upper clamping plate 8 is elastically arranged at the top of each inner groove 6, and a lower clamping plate 9 is slidably arranged at its bottom. The operator places the nylon elastic knitted fabric to be relaxed on the top of the lower clamping plate 9 in the inner groove 6, and then pre-clamps the fabric using the elastically arranged upper clamping plate 8. An electric drive assembly 4 is located on the top of the worktable 1, and the electric drive assembly 4 is used to drive the sliding plates 3 to slide on the top of the worktable. Under the action of the electric drive component 4, it is easy for the staff to control the sliding plate 3 to slide to both sides. Since the bottom end of the lower clamping plate 9 passes through the sliding plate 3 and is connected to the guide post 11, and the top of the worktable 1 is provided with a special-shaped groove 5 for the guide post 11 to slide, the lower clamping plate 9 is driven to slide upward through the cooperation of the special-shaped groove 5 and the guide post 11, thereby completing the limiting clamping work of the nylon elastic knitted fabric. In conjunction with the heat treatment component 7 on the worktable 1, it is pre-relaxed. During the subsequent reset process, the lower clamping plate 9 is reset through the guide post 11. At this time, it is easy for the staff to directly remove the nylon elastic knitted fabric from the sliding plate 3. This process reduces the overall clamping burden and improves the efficiency of the pre-relaxation treatment.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A return spring 10 is wrapped around the outer wall of the guide post 11, and the other end of the return spring 10 is located inside the sliding plate 3. When the guide post 11 slides upward under the action of the irregular groove 5, it will squeeze the return spring 10 at the top. During this process, the return spring 10 itself is in a compressed state. When the sliding plate 3 is reset, the guide post 11 drives the lower clamping plate 9 to slide downward under the reset action of the return spring 10, thereby releasing the lower clamping plate 9 from the limiting clamping work of the nylon elastic knitted fabric.

[0037] Second embodiment:

[0038] Please see Figure 1 The nylon elastic knitted fabric pre-relaxation device shown has an overall structure similar to that of Embodiment 1. A placement plate 2 is positioned at the top center of the workbench 1, and the placement plate 2 is concave. During the stretching process, the placement plate 2 supports the middle of the nylon elastic knitted fabric, ensuring its overall flatness and increasing the contact area with the heat treatment components. The placement plate 2 is sealed at its center, with a series of through holes extending outwards. When the heat treatment components 7 blow hot air, the sealed design allows the hot air to diffuse outwards and dissipate through the through holes to the bottom of the nylon elastic knitted fabric, further improving the working efficiency of the heat treatment components 7.

[0039] In practical operation, this invention involves placing the nylon elastic knitted fabric to be relaxed on the top of the placement plate 2, then inserting both ends into the inner grooves 6 of the sliding plate 3. The upper clamping plate 8 and lower clamping plate 9 work together to pre-clamp the nylon elastic knitted fabric. The electric drive assembly 4 then drives the sliding plate 3 to slide to both sides. During this process, the guide post 11 moves upward under the action of the irregular groove 5, thereby causing the lower clamping plate 9 to slide upward, thus achieving the limiting clamping of the nylon elastic knitted fabric. Furthermore, an array of heat treatment components 7 is located at the top of the workbench 1. These components work together to perform pre-relaxation treatment. The electric drive assembly 4 then drives the fabric to reset and slide. During this process, the guide post 11 slides downward to contact the lower clamping plate 9, limiting the clamping and allowing the worker to directly remove the nylon elastic knitted fabric from the sliding plate 3. This reduces the overall clamping burden and improves the efficiency of the pre-relaxation treatment.
