Description

Technical Field

[0001] This utility model belongs to the technical field of fabric forming devices, and in particular relates to an elastic warp-knitted fabric forming device. Background Technology

[0002] In the traditional elastic warp-knitted fabric weaving process, the lateral movement of the guide bars is a crucial step. However, existing warp-knitted fabric forming devices have certain problems with the positioning of the drive cams and the fixing methods of the connecting rings in the guide bar lateral movement mechanism.

[0003] The driving cam's positioning on the connecting ring is not stable enough. During operation, the driving cam is prone to rotating independently, affecting the lateral movement accuracy of the guide bar and consequently leading to a decrease in the weaving quality of the warp-knitted fabric, resulting in unclear patterns and unstable dimensions. Furthermore, the connecting ring is prone to displacement during rotation, making the entire guide bar lateral movement mechanism unstable, increasing the equipment failure rate and reducing production efficiency. In addition, the existing connecting ring fixing method is complex to operate, making it inconvenient to install and disassemble the connecting ring for maintenance, increasing the labor intensity of workers and production costs. Therefore, a flexible warp-knitted fabric forming device that can solve the above problems is needed.

[0004] To address the aforementioned problems, this utility model document proposes an elastic warp-knitted fabric forming device. Utility Model Content

[0005] The purpose of this invention is to provide an elastic warp-knitted fabric forming device. By moving the movable baffle on the surface of the threaded ring, and cooperating with the fixed baffle, multiple connecting rings are squeezed and fixed. The device is simple and convenient to operate, facilitates the installation, disassembly and maintenance of the connecting rings, reduces the labor intensity of workers, lowers production costs, and solves existing technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] An apparatus for forming elastic warp-knitted fabric, used for weaving elastic warp-knitted fabric, comprising:

[0008] A frame, wherein a needle bed is provided inside the frame, a crossbar is provided inside the frame, a comb bar slides on the surface of the crossbar, and a comb bar lateral movement mechanism is fixed to the side end of the frame for driving the comb bar to reciprocate lateral movement;

[0009] The comb transverse movement mechanism includes a rotating shaft rotatably disposed on the side end of the frame. A connecting roller is fixed on the surface of the rotating shaft. A positioning cylinder is fixed on the surface of the connecting roller. Multiple connecting rings are sleeved on the surface of the positioning cylinder. A retaining edge is fixed on the surface of each of the multiple connecting rings. Multiple receiving gaps are formed between the multiple retaining edges and the multiple connecting rings. The multiple receiving gaps are used to receive a drive cam. In order to facilitate the positioning of the drive cam, a set of positioning components is provided between the drive cam and the corresponding connecting ring.

[0010] To facilitate the positioning of multiple connecting rings, a set of extrusion components is provided on the surface of the connecting roller. The extrusion components are used to clamp and fix the multiple connecting rings on the surface of the positioning cylinder.

[0011] A limiting component is provided between the positioning cylinder and the multiple connecting rings to prevent the multiple connecting rings from shifting during rotation.

[0012] Optionally, each of the positioning components includes two inserts fixed inside the drive cam, and two slots are provided inside the connecting ring, with the two inserts sliding in the two slots respectively;

[0013] Specifically, the position of the drive cam is fixed by inserting a plug into the slot, so that the drive cam will not rotate independently.

[0014] Optionally, the limiting component includes two sliding grooves formed in the inner wall of multiple connecting rings, and two sliders are fixed on the surface of the positioning cylinder, with the multiple sliding grooves sliding on the surfaces of the two sliders respectively.

[0015] Optionally, a fixed baffle is fixed to the surface of the positioning cylinder, a threaded ring is fixed to the surface of the connecting roller, and a movable baffle is threadedly connected to the surface of the threaded ring;

[0016] In this process, the movable baffle moves threadedly on the surface of the threaded ring, and the movable baffle and the fixed baffle work together to squeeze and fix multiple connecting rings.

[0017] Optionally, anti-slip pads are fixed to the adjacent ends of both the movable baffle and the fixed baffle.

[0018] Optionally, multiple connecting rings are installed to form a cylinder, and a buffer gap is formed between the cylinder and the positioning cylinder. The buffer gap is used to provide compression space for the movable baffle.

[0019] In this application, the position of the drive cam is fixed by inserting a plug into the slot, so that the drive cam will not rotate independently;

[0020] The movable baffle moves along the surface of the threaded ring, and the movable baffle and the fixed baffle work together to squeeze and fix multiple connecting rings.

[0021] In this utility model, the elastic warp-knitted fabric forming device uses a movable baffle to move along the threaded surface of the threaded ring, and works in conjunction with a fixed baffle to press and fix multiple connecting rings. The operation is simple and convenient, and it is easy to install, disassemble and maintain the connecting rings, thereby reducing the labor intensity of workers and lowering production costs.

[0022] In this utility model, the elastic warp-knitted fabric forming device restricts the displacement of the connecting ring during rotation by sliding the slider in the groove, which enhances the stability of the comb bar transverse mechanism, reduces the failure rate of the equipment, and improves production efficiency.

[0023] In this technical solution, the extrusion assembly is designed to extrude and fix multiple connecting rings by moving the movable baffle on the threaded surface of the threaded ring and cooperating with the fixed baffle. The operation is simple and convenient, and it is easy to install, disassemble and maintain the connecting rings, thereby reducing the labor intensity of workers and lowering production costs.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0034] In one embodiment:

[0035] Please see Figures 1-4 As shown, this embodiment provides an elastic warp-knitted fabric forming device, comprising a frame 1, within which a needle bed 2 is installed to support and guide the knitting needles during the knitting process. A crossbar is also provided within the frame 1, with guide bars 3 slidably mounted on its surface. The guide bars 3 can reciprocate along the crossbar to facilitate yarn padding during the warp-knitted fabric knitting process. A guide bar lateral movement mechanism 4 is fixedly installed on the side of the frame 1, driving the guide bars 3 to reciprocate laterally.

[0036] The specific structure of the comb transverse movement mechanism 4 is as follows: A rotating shaft is rotatably installed on the side end of the frame 1, and a connecting roller 5 is fixed on the surface of the rotating shaft. A positioning cylinder 16 is fixed on the surface of the connecting roller 5. Multiple connecting rings 10 are sleeved on the surface of the positioning cylinder 16, and a flange 9 is fixed on the surface of each connecting ring 10. Multiple receiving gaps are formed between the multiple flanges 9 and the multiple connecting rings 10, and each receiving gap is used to receive the drive cam 11.

[0037] To facilitate the positioning of the drive cam 11, a set of positioning components is provided between the drive cam 11 and the corresponding connecting ring 10. Each positioning component includes two inserts 12 fixed inside the drive cam 11, and two slots 13 are provided inside the connecting ring 10. The two inserts 12 are slidably installed in the two slots 13 respectively. When the inserts 12 are engaged in the slots 13, the position of the drive cam 11 can be fixed, preventing the drive cam 11 from rotating independently.

[0038] To prevent displacement of the multiple connecting rings 10 during rotation, a limiting assembly is provided between the positioning cylinder 16 and the multiple connecting rings 10. The limiting assembly includes two sliding grooves 15 formed in the inner wall of the multiple connecting rings 10, and two sliders 14 fixed to the surface of the positioning cylinder 16. The multiple sliding grooves 15 are slidably mounted on the surfaces of the two sliders 14 respectively. In this way, when the connecting rings 10 rotate, the sliders 14 slide within the sliding grooves 15, which can limit the displacement of the connecting rings 10.

[0039] To facilitate the positioning of multiple connecting rings 10, a set of extrusion components is provided on the surface of the connecting roller 5. A fixed baffle 6 is fixed to the surface of the positioning cylinder 16, and a threaded ring 8 is fixed to the surface of the connecting roller 5. A movable baffle 7 is threadedly connected to the surface of the threaded ring 8. By rotating the movable baffle 7, it moves threadedly on the surface of the threaded ring 8. The movable baffle 7 and the fixed baffle 6 cooperate to extrude and fix the multiple connecting rings 10. Anti-slip pads are fixed to the adjacent ends of the movable baffle 7 and the fixed baffle 6 to increase the friction between them and the connecting rings 10, thereby improving the fixing effect.

[0040] In another embodiment:

[0041] Improvements based on Example 1: See Appendix Figure 1 - Appendix Figure 4 An elastic warp-knitted fabric forming device is disclosed, wherein multiple connecting rings 10 are installed to form a cylindrical body, and a buffer gap is formed between the cylindrical body and the positioning cylinder 16. The buffer gap is used to facilitate the provision of compression space for the movable baffle 7. When the movable baffle 7 moves towards the fixed baffle 6, the connecting rings 10 can be effectively compressed within the buffer gap.
