In the traditional process, different threads and piles are manually sorted out before the pile planting process, and the threads are manually threaded, so as to provide threads and piles for 8-shaped knot weaving. However, when the existing pile thread is cut, only the pile thread is simply cut, and the cut pile thread is not clamped and fixed, which leads to the problem that the other end of the pile thread cannot be threaded on the threading piece of the board mechanism, thereby affecting the subsequent processing of the carpet. Therefore, a thread cutting mechanism for carpet processing is needed to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0024] Please see Figures 1-5 This embodiment provides the following technical solution: a thread-cutting mechanism for carpet processing, including a frame 1, on which a thread-feeding mechanism, a thread-cutting mechanism 2, a trolley mechanism 3, a thread-pulling mechanism 4, and a thread-threading mechanism 5 are arranged. In some embodiments, the thread-feeding mechanism is arranged on the front side of the frame 1, the trolley mechanism 3 is arranged on the rear side of the thread-feeding mechanism and below the thread-pulling mechanism 4, the thread-cutting mechanism 2 is arranged between the thread-feeding mechanism and the trolley mechanism 3, and the thread-threading mechanism 5 is arranged on the rear side of the trolley mechanism 3.

[0025] In some embodiments, multiple wire feeding mechanisms are provided, with the wire cutting mechanism 2, the wire pulling mechanism 4, and the wire threading mechanism 5 corresponding to the wire feeding mechanism one by one.

[0026] The wire cutting mechanism 2 includes a cutting frame 21, which is fixedly connected to the frame 1. An upper moving frame 22 is vertically and slidably connected to the cutting frame 21. Two wire clamping grippers 23 are horizontally and slidably connected to the rear side of the upper moving frame 22, and a cutter 24 is horizontally and slidably connected to the front side of the upper moving frame 22.

[0027] In some embodiments, the upper thread pulling mechanism 4 of the carpet processing equipment pulls the yarn head on the thread feeding mechanism to perform a thread pulling operation. After the yarn is pulled to a designated position, the two thread clamping grippers 23 cooperate to clamp and fix the yarn, and under the horizontal sliding action of the cutter 24, the fixed yarn is cut.

[0028] It also includes an upward moving cylinder 27, the cylinder of which is fixedly connected to the shearing frame 21, and the piston rod of which is fixedly connected to the upward moving frame 22. The upward moving cylinder 27 enables the upward moving frame 22 to reciprocate in the vertical direction. When the upward moving frame 22 moves upward, it can clamp and fix the yarn. When the upward moving frame 22 moves downward, it can pull the cut yarn downward.

[0029] It also includes a thread-cutting cylinder 28, the cylinder of which is fixedly connected to the upper moving frame 22. The piston rod of the thread-cutting cylinder 28 is fixedly connected to the cutter 24, which is used to make the cutter 24 slide horizontally to cut the yarn. Through the thread-cutting cylinder 28, the cutter 24 can slide horizontally back and forth, so that the yarn in the clamped state can be cut under the action of the cutter 24.

[0030] It also includes a pneumatic gripper 29, the cylinder of which is fixedly connected to the rear side of the upper moving frame 22. The two clamping plates of the pneumatic gripper 29 are respectively fixedly connected to two thread clamping grippers 23. Through the pneumatic gripper 29, the two thread clamping grippers 23 can move closer or further away at the same time, so that the thread clamping grippers 23 can clamp and fix the yarn, or release the yarn.

[0031] In some embodiments, the wire clamp 23 is disposed between the spring 252 and the cutter 24.

[0032] A thread clamp 25 is mounted on the frame 1 and located on one side of the upper moving frame 22. A thread presser 26 is mounted above the thread clamp 25. The thread presser 26 and the thread clamp 25 work together to form a clamping structure for the yarn. In some embodiments, the thread clamp 25 includes a thread clamping frame 251 and a spring 252. The thread clamping frame 251 is fixedly connected to the frame 1. The spring 252 is mounted above the thread clamping frame 251. Several spaced retaining rings 253 are fixedly connected to the outside of the spring 252. The retaining rings 253 are fixedly connected to the thread clamping frame 251. A thread presser 26 is mounted above the thread clamp 25. The thread presser 26 includes a thread presser frame 261. The thread presser frame 261 is mounted above the thread clamping frame 251 and fixedly connected to the frame 1. A pressing cylinder 262 is fixedly connected to the pressing frame 261. A pressing block 263 is mounted on the piston rod of the pressing cylinder 262 for pressing the yarn into the gap on the spring 252.

[0033] In some embodiments, after the yarn is clamped and fixed by the yarn clamping gripper 23 via the yarn clamping gripper 25 and the yarn pressing gripper 26, the cutter 24 can cut the clamped and fixed yarn. After the cut yarn ends are pulled down and pressed down, they can be fixed inside the yarn clamping gripper 25, which facilitates the clamping and fixing of the yarn and avoids affecting subsequent processing steps due to the failure to fix the yarn.

[0034] The working principle of this utility model is as follows: The thread-pulling mechanism 4 on the frame 1 pulls the yarn from the thread-feeding mechanism to the designated position on the trolley mechanism 3. Then, the upward-moving cylinder 27 is activated, causing the upward-moving frame 22 to drive the pneumatic gripper 29 to move upward. The pneumatic gripper 29 is activated, causing the thread-clamping handles 23 on both sides to simultaneously approach and clamp the yarn. Then, the thread-cutting cylinder 28 is activated, causing the cutter 24 to slide to the right to cut the yarn. After cutting, the upward-moving cylinder 27 drives the upward-moving frame 22 and the pneumatic gripper 29 to move upward. The gripper 29 moves downward, causing the pneumatic gripper 29 to pull down the cut yarn end, so that the yarn end is located below the front side of the spring 252. Then, the pressing cylinder 262 is activated, causing the pressing block 263 to move downward and press down on the yarn located behind the spring 252. This causes the yarn end to be pressed down into the gap of the spring 252 under the tension, thus completing the clamping and fixing of the cut yarn. The operation is repeated to clamp and fix one end of the yarn segment of equal length to the spring 252 in turn.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
