Description

Technical Field

[0001] This application relates to the field of rapier looms, and in particular to a waste edge collection device for a rapier loom. Background Art

[0002] The rapier loom is the most widely used shuttleless loom. In addition to the characteristics of high speed, high automation degree, and high production efficiency of shuttleless looms, its positive weft insertion method has strong variety adaptability and can adapt to the weft insertion of various yarns. Moreover, the rapier loom also has obvious advantages in multi-color weft weaving and can produce figured fabrics with up to 16 color wefts. The fabric woven by the rapier loom is a sheet fabric, and there will be excess waste edges on both sides of the fabric. When the fabric goes through the next process, it is necessary to cut off the waste edges on both sides of the fabric and collect the waste edges.

[0003] Chinese Patent with the authorization announcement number CN206359709U discloses a waste edge disc assembly for a rapier loom, aiming to solve the problem of low processing stability of the waste edge disc assembly of the rapier loom; the key points of its technical solution are a waste edge disc assembly for a rapier loom, including a bracket and a waste edge disc. A yarn unwinding rod passes through the waste edge disc and is fixedly connected to the waste edge disc. A counterweight block is arranged below the waste edge disc, and a connecting belt made of a soft material is arranged on the counterweight block. One end of the connecting belt is connected to the counterweight block, and the other end bypasses the bracket and is connected to a rotating block. The yarn unwinding rod passes through the rotating block and is rotatably connected to the rotating block. A stop block is arranged below the bracket, and the yarn unwinding rod abuts against the lower end of the stop block under the action of the counterweight block and the connecting belt. This utility model has high processing stability for a waste edge disc assembly of a rapier loom.

[0004] In view of the above related technologies, after winding is completed, it is necessary to completely disassemble the waste edge disc in order to remove the waste edge wound on the waste edge disc, and the operation is relatively inconvenient. Summary of the Utility Model

[0006] A waste edge collection device for a rapier loom provided by this application adopts the following technical solution:

[0007] A waste edge collection device for a rapier loom, comprising a frame, a guiding roller, and a winding roller. The frame is used to connect with the loom body. The guiding roller is rotatably connected to the frame and is used to guide the waste edge to the winding roller. The frame is rotatably connected with a disc, and the frame is connected with a rotating member, which is used to drive the disc to rotate. The winding roller includes a plurality of support plates. One end of each support plate along its length direction is connected to one side of the disc, and the support plates are sequentially and spaced apart along the circumferential direction of the disc.

[0008] By adopting the above technical solution, the waste edge is guided to the winding roller through the guiding roller, and the waste edge is wound around a plurality of support plates along the circumferential direction of the disc. When the support plates are wound with the waste edge, the support plates move radially along the disc, and the radial position of the support plates is adjusted through the radial positioning component. The support plates approach each other, reducing the distance between the support plates, so as to facilitate the removal of the waste edge from the support plates.

[0009] Optionally, a sleeve is connected in the installation cavity. The length direction of the sleeve is the same as the length direction of the support plate.

The radial positioning component includes a positioning block and a resetting member. The positioning block passes through and is slidably connected in the positioning hole along the radial direction of the support rod. One end of the positioning block is connected to the side of the support plate close to the installation cavity.

The resetting member is used to drive the positioning block to move radially along the support rod and drive the support plate close to the support rod. When the positioning block contacts the support plate, the plurality of support plates move away from each other.

[0010] By adopting the above technical solution, during use, the moving member drives the positioning block to move radially along the support rod, and one end of the positioning block radially passes through and contacts the support plate along the support rod, and pushes the support plate to move radially along the disc. When the support plate is wound with the waste edge, the resetting member drives the positioning block to move radially along the support rod and drives the support plate to move radially along the disc, so that the plurality of support plates approach each other, reducing the distance between the support plates, so as to facilitate the removal of the waste edge from the support plates.

[0012] By adopting the above technical solution, when the waste edge is wound on the support plate, the support rod can be rotated, so that the mounting groove communicates with the positioning hole, thereby facilitating the positioning block to move radially along the support rod and embed into the mounting groove, causing the positioning block to drive the support plate to move radially along the disc and reducing the distance between the support plates, thereby facilitating the removal of the waste edge from the support plate. During winding, the support rod is rotated, under the guiding action of the guiding surface, the positioning block moves radially along the support rod and away from the support rod, the positioning block drives the support plate to move radially along the disc, and the support plate moves away from the support rod, thereby resetting the support plate and increasing the distance between several support plates.

[0013] Optionally, a first limiting groove is formed on one side of the positioning hole along the circumferential direction of the sleeve, the length direction of the first limiting groove is consistent with the length direction of the mounting groove, a second limiting groove is formed on one side of the mounting groove along the circumferential direction of the support rod, the length direction of the second limiting groove is consistent with the length direction of the mounting groove, the first limiting groove communicates with the second limiting groove, the resetting member includes a limiting block and a first spring, the limiting block is connected to one side of the positioning block along the circumferential direction of the sleeve, the limiting block is slidably connected in the first limiting groove and the second limiting groove along the length direction of the mounting groove, the length direction of the first spring is consistent with the length direction of the mounting groove, one end of the first spring is connected to the inner wall of the first limiting groove, and the other end of the first spring is connected to the limiting block. When the support plate moves away from the support rod, the first spring is compressed and deformed.

[0014] By adopting the above technical solution, during winding, the first spring is compressed and deformed. When the waste edge is wound on the support plate, the support rod is rotated to make the mounting groove communicate with the positioning hole, the first spring resumes its shape and drives the limiting block to move radially along the support rod in the first limiting groove and the second limiting groove, and the limiting block drives the positioning block to embed into the mounting groove, and the support plate moves along with the positioning block and approaches the support rod.

[0015] Optionally, the frame is further connected with an adjusting roller, the adjusting roller, the guiding roller and the winding roller are distributed in sequence along the transmission direction of the waste edge, the frame is connected with an adjusting component, and the adjusting component is used for adjusting the position of the adjusting roller, thereby adjusting the tension of the waste edge.

[0016] By adopting the above technical solution, the waste edge passes through the adjusting roller and the guiding roller in sequence. The position of the adjusting roller is adjusted by the adjusting component, and the distance between the adjusting roller and the guiding roller is adjusted in sequence, thereby adjusting the tension of the waste edge, and trying to avoid the situation that the waste edge drops into the gap between the supporting plates during the winding process due to the small tension of the waste edge, thereby affecting the movement of the supporting plates.

When the fabric tension is too large, the fabric pushes the adjusting roller to move upward in the vertical direction, so that the third spring is compressed and deformed, thereby reducing the distance between the adjusting roller and the guiding roller, thereby reducing the tension of the fabric. When the fabric tension is too small, the third spring returns to its original shape and pushes the adjusting roller to move downward in the vertical direction, thereby increasing the distance between the adjusting roller and the guiding roller, thereby increasing the tension of the fabric.

[0019] Optionally, the frame is connected with a guide coil, and the frame is connected with a driving member for driving the guide coil to move along the length direction of the winding roller.

[0020] By adopting the above technical solution, during winding, the driving member drives the guide coil to move back and forth along the length direction of the supporting plate, thereby enabling the waste edge to be evenly distributed on the surface of the winding roller and improving the winding amount of the waste edge by the winding roller.

[0021] Optionally, a handle is connected to the end of the support rod away from the disc.

[0025] 2. When the waste edge is wound around the support plate, the support rod can be rotated so that the installation groove communicates with the positioning hole, facilitating the radial movement of the positioning block along the support rod and its embedding into the installation groove. The positioning block drives the support plate to move radially along the disc, reducing the distance between the support plates, thus facilitating the removal of the waste edge from the support plate. During winding, when the support rod is rotated, under the guiding action of the guiding surface, the positioning block moves radially along the support rod and away from the support rod. The positioning block drives the support plate to move radially along the disc, and the support plate moves away from the support rod, resetting the support plate and increasing the distance between several support plates.

[0026] 3. The waste edge passes through the adjusting roller and the guiding roller in sequence. The position of the adjusting roller is adjusted by the adjusting component, and the distance between the adjusting roller and the guiding roller is adjusted in sequence, thereby adjusting the tension of the waste edge, and trying to avoid the situation that the waste edge falls into the gap between the support plates during the winding process due to the small tension of the waste edge, which affects the movement of the support plate.

One end of the support plate 210 along its length direction is connected to one side of the disk 110 along the axial direction of the disk 110. The support plate 210 is connected to the disk 110 by sliding along the radial direction of the disk 110. The disk 110 is connected to a radial positioning assembly 300, which drives the support plate 210 to slide along the radial direction of the disk 110 and is connected to the disk 110.

One end of the support rod 600 away from the disc 110 is connected with a handle 610. Six installation grooves 620 are formed on the circumferential side of the support rod 600. The six installation grooves 620 are sequentially and equally spaced along the circumferential direction of the support rod 600.
