Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, specifically relating to a rapier loom pressure device for producing strong ribbed fabric. Background Technology

[0002] Reinforced woven fabric is a special type of fabric incorporating reinforcing materials (such as plastic film, glass fiber, carbon fiber, etc.) during the weaving process to enhance its strength and durability. It is widely used in the construction industry, outdoor equipment, and transportation sectors. Reinforced woven fabric can be woven using a rapier loom. The rapier belt (also called the rapier head belt or rapier shaft belt) is a key component of the rapier loom. The rapier head on the rapier belt clamps the weft yarn on one side of the loom. The rapier belt pulls the weft yarn through the shed, while the warp yarn is lifted to form the shed. The rapier belt releases the weft yarn on the other side of the loom, and the weft yarn is tightened by the reed to form the fabric.

[0003] A search revealed a Chinese patent (publication number: CN216193076U) that discloses a rapier loom belt pressure device, comprising a rapier wheel, a lead screw, a support frame, and a pressure roller. A rapier belt is arranged around the rapier wheel, and a pressure support is provided on one side of the rapier wheel. A groove is provided on the top of the pressure support, and a slider is slidably connected within the groove. A sliding support is provided on the top of the slider. In actual use, since the pressure on the rapier belt is adjusted by moving the pressure roller through the lead screw, the pressure applied to the pressure roller may be unevenly distributed, leading to uneven stress on the rapier belt. This can cause the weft yarn to break due to unstable tension during transmission. Therefore, a rapier loom belt pressure device for producing high-strength fabric is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pressure device for the rapier belt of a rapier loom used in the production of reinforced fabric, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapier loom scissor belt pressure device for producing reinforced fabric, comprising:

[0006] The equipment body includes a scimitar pulley, a scimitar belt, and a mounting frame. The scimitar belt is mounted on the scimitar pulley, and the mounting frame is disposed on the scimitar pulley.

[0007] A pressurizing assembly includes a pressurizing wheel, a rotating rod, a connecting rod, a screw, and a rotating drum. The pressurizing wheel is rotatably mounted coaxially with the rotating rod. The connecting rod is connected to both ends of the rotating rod. The screw is installed at the middle position of the connecting rod and is threadedly connected to the rotating drum. The rotating drum is rotatably mounted on the mounting frame. The pressurizing wheel is in contact with the belt, and the belt pulley is parallel to the axial direction of the pressurizing wheel.

[0008] A support rod is provided on the mounting bracket.

[0009] As a preferred embodiment, the mounting bracket has grooves on opposite sides, and the pressurizing assembly further includes a pair of sliders, which are respectively fixedly mounted on both ends of the connecting rod and slidably placed in the grooves.

[0010] As a preferred embodiment, the mounting bracket has a fixing groove on one side forming the slide, the slider has a threaded hole, the support rod passes through the fixing groove, and one end of the support rod is threadedly connected to the threaded hole.

[0011] As a preferred embodiment, the mounting bracket has a mounting hole, and the screw extends upward from the connecting rod through the mounting hole by a certain distance.

[0012] As a preferred embodiment, the main body of the device further includes a fixed cylinder, which is mounted on the upper surface of the mounting frame, and the rotating cylinder is rotatably placed in the fixed cylinder.

The pressure wheel is rotatably mounted coaxially with the rotating rod, the connecting rod is connected to both ends of the rotating rod, and the screw is installed in the middle of the connecting rod. Before starting the machine, the operator rotates the rotating drum, causing the screw and the connecting rod connected to the screw to move along the screw's axial direction until the pressure wheel connected to the connecting rod is fully engaged with the rapier belt. This ensures that the pressure wheel can apply a certain pressure to the rapier belt, preventing the weft yarn connected to the rapier belt from jumping due to slack during transmission and avoiding breakage due to unstable tension during weft yarn introduction. Furthermore, the operator can adjust the rotation of the rotating drum according to different weft yarn materials, thereby adjusting the pressure between the pressure wheel and the rapier belt.

[0016] This invention features a support rod and a mounting bracket with a fixed groove on one side forming the slide groove. The slider has a threaded hole, and the support rod is inserted into the fixed groove, with one end of the support rod threadedly connected to the threaded hole. A worker inserts one support rod into the fixed groove on one side and places it in the threaded hole on the slider. Then, the support rod is rotated to ensure a tight connection between the support rod and the threaded hole. Similarly, the other support rod also fixes the slider on the other side of the connecting rod in the slide groove, making the pressure applied by the pressure wheel to the rapier belt more even, preventing the rapier belt from shifting on the rapier belt pulley, and ensuring accurate weft yarn introduction.
