Description

Technical Field

[0001] The utility model relates to the technical field of textile machines, in particular to a weft insertion mechanism of a silk loom for weaving mesh rings. Background Art

[0002] The mesh ring plays a very important role in the process of yarn gathering. The mesh ring is a "conveyor belt" and also a "condenser". Its task is to carry the yarn flakes that have completed the drafting process, and continue to move forward at the synchronous speed of the output roller, so that the airflow can gather the fiber bundles until they enter the twisting area. The mesh ring is required to have good "air permeability" and be able to allow the airflow to pass stably. Therefore, the technical requirements for the mesh ring are very high, so it needs to be processed by the weft insertion mechanism of the silk loom during the production process.

[0003] The patent specification with the announcement number CN219930391U discloses a weft insertion mechanism of a silk loom for weaving a mesh ring, including a mechanism body, a weft insertion seat and a mounting strip, an easy-to-disassemble mechanism is arranged outside the mechanism body, the easy-to-disassemble mechanism includes a slide bar, a connecting plate and a No. 1 spring, a placement groove is provided on the upper side of the mechanism body, and a slot is provided on the outside of the placement groove; a fixed rod is fixedly connected to the inner side of the mechanism body, and a weft insertion roller is rotatably connected to the outside of the fixed rod, a reset mechanism is arranged on one side of the mounting strip, the reset mechanism includes a telescopic rod and a No. 2 spring, and a scraper is fixedly connected to the other side of the mounting strip. Through the slide bar, the No. 1 spring and the slot, the purpose of facilitating the rapid disassembly and assembly of multiple sets of weft insertion seats can be achieved, and through the weft insertion roller, the No. 2 spring and the scraper, the dirt contaminated by the spinning thread in the atmosphere can be scraped off to ensure that its textile quality is not affected.

[0004] However, in the implementation of relevant technologies, it was found that the weft insertion mechanism of a silk loom with a weaving grid loop designed as above has the following problems: in the prior art, components such as sliding rods are used to allow the weft insertion mechanism to scrape off contaminated dirt when conveying the yarn. However, in actual use, due to vibrations generated by the operation of the textile device or looseness of the winding device, the yarns may become close to each other or even entangled during the conveying process. In view of this, a weft insertion mechanism of a silk loom with a weaving grid loop is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a weft insertion mechanism for a silk loom for weaving mesh loops.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a weft insertion mechanism of a silk loom for weaving a mesh ring, comprising a mounting shell, a separation mechanism being arranged at the front end of the mounting shell;

[0007] The separation mechanism includes a mounting block, which is fixedly mounted on the front end of the mounting shell, and a first damping spring is embedded in the inner bottom end of the mounting block, the top end of the first damping spring is connected to a bearing block, and two axially opposite surfaces of the bearing block are rotatably connected to a first conveying wheel, and the upper part of the mounting block is rotatably connected to a second conveying wheel, and a placement groove is provided on the outer wall of the first conveying wheel. After the yarn wraps around the first conveying wheel and is limited by the placement groove, it fits the second conveying wheel and passes out, thereby limiting and separating the yarn and avoiding entanglement due to close proximity.

[0008] As a further description of the above technical solution: the mounting block forms an elastic structure with the supporting block through the first damping spring, and the structure of the supporting block is a U-shaped structure. The supporting block is elastically pushed by the first damping spring to allow the first conveying wheel and the second conveying wheel to fit together, thereby limiting the spinning line in the placement groove to prevent it from falling out.

[0009] As a further description of the above technical solution: sliding grooves are opened on both sides of the interior of the mounting block, and sliding blocks are fixed at the positions of the outer wall of the supporting block corresponding to the sliding grooves. Through the cooperation of the sliding grooves and the sliding blocks, the supporting block can remain stable and avoid displacement when the first damping spring is elastically extended and retracted.

[0010] As a further description of the above technical solution: a structural frame is fixed to the front end of the mounting block, and rollers are rotatably connected to two axially opposite surfaces of the structural frame, and rubber pads are provided on the outer walls of the rollers. The spinning thread resists the rollers rotatably connected to the structural frame, and the rubber pads on the outside of the rollers wipe and absorb the external dust of the spinning thread during transmission.

[0011] As a further description of the above technical solution: a placement groove is opened at the top of the mounting shell, and a weft insertion device is inserted into the interior of the placement groove. The shell below the weft insertion device matches the size of the placement groove, which is easy to insert and thus plays a preliminary limit role to avoid shaking.

[0012] As a further description of the above technical solution: a positioning mechanism is arranged below the separation mechanism at the front end of the mounting shell, and the positioning mechanism includes a mounting hole, and the mounting holes are opened on both sides of the outer wall of the weft insertion device, and a second damping spring is embedded in the inside of the mounting hole, and one end of the second damping spring is connected to a protruding head, and limiting holes are opened on both sides of the outer wall of the mounting shell at the positions corresponding to the protruding heads. When the protruding heads correspond to the limiting holes, the second damping spring is elastically pushed to allow the protruding heads to slide through the mounting hole and penetrate into the limiting hole, thereby fixing the weft insertion device.

[0013] As a further description of the above technical solution: the penetration head is elastically connected to the weft insertion device through a second damping spring, and a sliding structure is formed between the penetration head and the weft insertion device. Through the elasticity of the second damping spring, it is easy to press the penetration head to facilitate rapid disassembly and assembly of the weft insertion device.

[0014] The utility model has the following beneficial effects:

[0015] The utility model designs a weft insertion mechanism for a silk loom for weaving a mesh ring. The first damping spring elastically pushes the bearing block to make the first conveying wheel and the second conveying wheel fit together. At the same time, the yarn penetrates into the placement groove and is transported under the support of the first conveying wheel and the second conveying wheel, so as to separate and isolate the yarns to avoid entanglement caused by approaching each other when loose. The bearing block is pressed through the sliding groove and the sliding block to make the first damping spring contract and place the yarn, so as to keep the bearing block sliding stably to avoid deviation.

[0016] The utility model designs a weft insertion mechanism for a silk loom for weaving a mesh ring. The spinning thread contacts a roller for conveying, and cooperates with a rubber pad to scrape and absorb spinning thread dust. When the weft insertion device enters a placement groove for initial limiting, a penetration head enters a limiting hole under the elastic push of a second damping spring, thereby fixing the weft insertion device. The weft insertion device can be disassembled by pressing the penetration head, thereby facilitating quick disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figure 1-4The utility model provides a weft insertion mechanism for a silk loom for weaving a mesh ring: it includes a mounting shell 1, and a separation mechanism 2 is arranged at the front end of the mounting shell 1; the separation mechanism 2 includes a mounting block 201, the mounting block 201 is fixedly mounted at the front end of the mounting shell 1, a first damping spring 202 is embedded in the inner bottom end of the mounting block 201, and a bearing block 203 is connected to the top of the first damping spring 202, and a first conveying wheel 204 is rotatably connected to the two axially opposite surfaces of the bearing block 203, and a second conveying wheel 206 is rotatably connected to the upper part of the mounting block 201, and a placement groove 205 is opened on the outer wall of the first conveying wheel 204. After the yarn goes around the first conveying wheel 204 for one circle and is limited by the placement groove 205, it fits the second conveying wheel 206 and passes through, thereby limiting and separating the yarn to avoid entanglement caused by being close to each other.

[0024] As a further implementation scheme of the above technical scheme: the mounting block 201 forms an elastic structure with the supporting block 203 through the first damping spring 202, and the structure of the supporting block 203 is a U-shaped structure. The first damping spring 202 elastically pushes the supporting block 203 to allow the first conveying wheel 204 and the second conveying wheel 206 to fit together, thereby limiting the spinning line in the placement groove 205 to prevent it from falling out.

[0025] As a further implementation scheme of the above technical scheme: sliding grooves 3 are opened on both sides of the interior of the mounting block 201, and sliders 4 are fixed on the outer wall of the supporting block 203 at positions corresponding to the sliding grooves 3. Through the cooperation of the sliding grooves 3 and the sliders 4, the supporting block 203 can remain stable and avoid displacement when the first damping spring 202 is elastically extended and retracted.

[0026] During specific implementation, the yarn enters the supporting block 203 inside the mounting block 201, passes through the placement groove 205, goes around the first conveying wheel 204, and then passes through the second conveying wheel 206, thereby limiting and separating the yarn to avoid mutual adhesion and entanglement. When the supporting block 203 is pressed through the slide groove 3 to allow the first damping spring 202 to shrink and insert the yarn, the supporting block 203 is kept stable during the sliding process of the slider 4 to avoid deviation and be staggered with the second conveying wheel 206.

[0027] As a further implementation scheme of the above technical scheme: a structural frame 5 is fixed to the front end of the mounting block 201, and rollers 6 are rotatably connected to the two axially opposite surfaces of the structural frame 5. The outer wall of the roller 6 is sleeved with a rubber pad 7. The roller 6 is rotatably connected to the structural frame 5 through the spinning thread, and the rubber pad 7 on the outside of the roller 6 wipes and absorbs the external dust of the spinning thread during transmission.

[0028] As a further implementation scheme of the above technical scheme: a placement groove 9 is opened at the top of the mounting shell 1, and a weft insertion device 8 is inserted into the placement groove 9. The shell below the weft insertion device 8 matches the size of the placement groove 9, which is easy to insert and thus plays a preliminary limit role to avoid shaking.

[0029] As a further implementation scheme of the above technical scheme: a positioning mechanism 10 is arranged below the separation mechanism 2 at the front end of the mounting shell 1, and the positioning mechanism 10 includes a mounting hole 1001, and the mounting hole 1001 is opened on both sides of the outer wall of the weft insertion device 8, and a second damping spring 1002 is embedded in the mounting hole 1001, and one end of the second damping spring 1002 is connected to a protruding head 1003, and limiting holes 1004 are opened at the positions of the protruding heads 1003 on both sides of the outer wall of the mounting shell 1. When the protruding heads 1003 correspond to the limiting holes 1004, the protruding heads 1003 are elastically pushed by the second damping spring 1002 to slide through the mounting hole 1001 and penetrate into the limiting hole 1004, thereby fixing the weft insertion device 8.

[0030] As a further implementation scheme of the above technical scheme: the protruding head 1003 is elastically connected to the weft insertion device 8 through the second damping spring 1002, and a sliding structure is formed between the protruding head 1003 and the weft insertion device 8. Through the elasticity of the second damping spring 1002, it is easy to press the protruding head 1003 to facilitate rapid disassembly and assembly of the weft insertion device 8.

[0031] During specific implementation, the drum 6 rotates in contact with the spinning thread under the support of the structural frame 5, and the dust adsorbed on the spinning thread is scraped off and cleaned through the outer wall rubber pad 7. When the weft insertion device 8 enters the placement groove 9, the protruding head 1003 corresponds to the limiting hole 1004, and the second damping spring 1002 elastically pushes the protruding head 1003 to slide along the installation hole 1001 and enter the limiting hole 1004, so as to quickly install the weft insertion device 8.
