Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a yarn pressing device for holding warp yarns on a cloth surface. Background Art

[0002] Weaving is an ancient and important craft and industry, which involves a series of processes to make various fiber materials into yarns, fabrics and textiles. During the operation of the loom, the warp yarn and the weft yarn are interwoven to form a woven product. During the operation, a yarn pressing device is used to press down the warp yarn.

[0003] The prior art, such as the utility model with publication number CN218842502U, discloses a yarn pressing device for holding the warp yarn of a cloth surface, comprising a crossbeam arranged on a loom, characterized in that: a yarn pressing mechanism is detachably and movably installed on the crossbeam, the yarn pressing mechanism comprises a mounting portion, a rotating connecting portion and a yarn pressing shaft, the mounting portion is movably mounted on the crossbeam, the top of the rotating connecting portion is rotatably connected to the bottom of the mounting portion, the yarn pressing shaft is rotatably connected to the bottom end side wall of the rotating connecting portion; a clamping portion is also provided on the mounting portion, and the middle portion of the rotating connecting portion is detachably connected to the clamping portion The utility model improves the convenience of operation for operators, reduces the labor intensity of operators, and reduces potential safety hazards. It solves the problem that operators need to press and hold the warp yarns after the joints and then release them after the loom starts (continues to run). In this way, there is a problem that when starting the machine, the operator presses and holds the warp yarns after the joints with his hands, which makes it dangerous when starting the machine. When starting the machine, textile work continues and the warp yarns will move instantly, which may cause the operator's hands to be cut by the warp yarns quickly pulled, thus posing certain potential safety hazards and increasing the labor intensity of operators.

[0004] In daily work, it is found that when the above-mentioned yarn pressing device is in use, the warp yarn is pressed down mainly by its own weight. During the pressing process, it is difficult to ensure that the pressing force is the same each time. Due to the force, the yarn pressing wheel is prone to jumping, which causes unnecessary displacement or jump of the warp yarn during the weaving process. As a result, the existing yarn pressing device has poor stability when pressing yarn, which easily causes the problem of warp yarn displacement and jump. Utility Model Content

[0008] Preferably, the inner wall of the placement rack is rotatably connected to a control rod, and the surface of the fitting part is fixedly connected to an arc-shaped part, and the control rod passes through the arc-shaped part. By rotating the control rod through the above components, the control rod can squeeze the arc-shaped part, and the arc-shaped part can drive the fitting part to move downward in the guide rod, thereby facilitating adjustment.

[0009] Preferably, the control rod includes a rotating rod, which is rotatably connected to the inner wall of the placement piece, and two extrusion blocks are fixedly connected to the surface of the rotating rod, and the extrusion blocks are located in the arc-shaped piece.

[0012] Preferably, a non-slip sheet is fixedly connected to a surface of one side of the fixing plate close to the placement rack, and the non-slip sheet can improve the non-slip effect after contacting the installation part through the above-mentioned components.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1.

The surfaces of the guide rods 58 are sleeved with a stabilizing spring 54, and the two ends of the stabilizing spring 54 are respectively fixedly connected to the surfaces of the guide rods 58 and the fitting 53.

[0026] In this embodiment: when pressing the yarn, the fitting part 53 can be pressed first, and the fitting part 53 under the force of the stabilizing spring 54 loses the restraint on the fixed ring 51, and the rotating arm 2 and the rotating rod 4 can be rotated, and the rotating arm 2 drives the pressing wheel 3 to press on the warp yarn. After the force is adjusted, the fitting part 53 is released, and the elastic force of the stabilizing spring 54 can make the fitting part 53 fit and squeeze on the fixed ring 51 to achieve an interference fit, so that the rotating arm 2 and the pressing wheel 3 can be limited, thereby improving the stable wire pressing effect.

[0027] Specifically, a plurality of groups of anti-skid particles 52 are fixedly connected to the surface of the fixing ring 51 , and the plurality of groups of anti-skid particles 52 are arranged at equal intervals.

[0028] In this embodiment, when the fitting member 53 contacts the fixing ring 51, the anti-skid particles 52 can increase the friction force and make it more stable.

[0029] Specifically, the inner wall of the placement rack 1 is rotatably connected to a control rod 56, and the surface of the fitting member 53 is fixedly connected to an arc-shaped member 55. The control rod 56 passes through the arc-shaped member 55. By rotating the control rod 56, the control rod 56 can squeeze the arc-shaped member 55, and the arc-shaped member 55 can drive the fitting member 53 to move downward in the guide rod 58, thereby facilitating adjustment.

[0030] Specifically, the control rod 56 includes a rotating rod 561 , which is rotatably connected to the inner wall of the placement piece. Two extrusion blocks 562 are fixedly connected to the surface of the rotating rod 561 , and the extrusion blocks 562 are located in the arc-shaped piece 55 .

[0031] In this embodiment, when the control rod 56 performs extrusion, the extrusion block 562 is driven to rotate mainly through the rotating rod 561 , and the extrusion block 562 extrudes the arc-shaped member 55 .

[0032] Specifically, both ends of the rotating rod 561 are fixedly connected with handles 57 , and by rotating the handles 57 , the rotating rod 4 and the two squeezing blocks 562 can be controlled to rotate, and the squeezing blocks 562 can squeeze the arc-shaped member 55 .

[0033] Specifically, the auxiliary device 6 includes a fixed plate 61, which is slidably connected to the inner wall of the placement rack 1. The inner wall of the fixed plate 61 is rotatably connected to a screw 63, which is threadedly connected to the inner wall of the fixed plate 61, and one end of the screw 63 is fixedly connected to a rotating head 64.

[0035] Specifically, a non-slip sheet 62 is fixedly connected to a surface of one side of the fixing plate 61 close to the placement rack 1 . After the non-slip sheet 62 contacts the installation part, the non-slip effect can be improved.

[0036] Working principle: When performing the yarn pressing operation, the placement frame 1 is installed on the equipment installation part, and then the rotating head 64 and the screw 63 are rotated. The screw 63 can control the fixed plate 61 to move, and the fixed plate 61 can cooperate with the placement piece to clamp the installation part. After the anti-slip sheet 62 contacts the installation part, the anti-slip effect can be improved. When pressing the yarn, the handle 57 drives the rotating rod 561 and the squeezing block 562 to rotate, and the squeezing block 562 can be squeezed with the arc piece 55, and then the arc piece 55 drives the fitting piece 53 to The guide rod 58 moves, the stabilizing spring 54 is stressed, and after the fitting part 53 loses contact with the fixed ring 51, the rotating arm 2 and the pressure wheel 3 can be rotated in the placement part. When the rotating arm 2 cooperates with the pressure wheel 3 to press down the warp yarn with a certain force, the handle 57 is released. The high strength of the stabilizing spring 54 can make the fitting part 53 stably fit on the fixed ring 51, and cooperate with the anti-slip particles 52 on the surface of the fixed ring 51 to increase the friction, thereby achieving the limitation of the rotating arm 2 and the pressure wheel 3, and improving the fixing and stabilizing effect during the yarn pressing process.
