Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rapier looms, in particular to a rapier opening device for a rapier loom. Background Art
[0002] Rapier looms are renowned for their high speed, stability, and adaptability. They are widely used in industries such as yarn-dyed weaving, quilts, silk, wool, and linen. They are the most versatile machine for weaving small and medium-sized batches of fancy fabrics and have evolved into a widely used and widely used shuttleless loom. Rapier looms come in many forms, and can be categorized by the configuration of the rapier: single rapier, double rapier, and double-layer, double-shuttle rapier. During the weaving process, the weft yarn is introduced by the weft-feeding and receiving rapiers, followed by the reed beating-off. As the reed moves forward, the weft yarn is clamped and beaten.
[0003] In the prior art, there are two main ways to open a rapier: one is to directly impact the rapier head with the rapier block to change its line-holding posture; the other is to use an electronic control system to assist in changing the relative position of the rapier block, thereby causing the line-holding posture of the rapier head to change regularly. During use, the rapier head may be damaged, resulting in a change in the line-holding posture, which affects subsequent work. When the rapier head is replaced for maintenance, it is not easy to remove and replacement is more troublesome.
[0004] This case was created to solve the above problems. Utility Model Content
[0005] (1) Technical problems solved
[0006] In view of the deficiencies in the prior art, the utility model provides a rapier loom rapier opening device, which solves the problems raised in the above background technology.
[0007] (2) Technical solution
[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a rapier loom sword opening device, including a rapier, the front end of the rapier is connected to a connecting block, the front side of the connecting block is connected to a rapier head, a card and assembly are provided in the rapier, the card and assembly include a spring assembly, a clamping block, a connecting head, and a displacement block, and the end of the rapier head passes through the connecting block and is sleeved on the connecting head.
[0009] Preferably, one end of the spring assembly is fixedly connected to a fixed plate, the fixed plate is located inside the support plate, and the other side of the fixed plate is fixedly connected to a connecting rod, the connecting rod is located outside the rapier and has a handle fixedly connected thereto.
[0010] Preferably, the other end of the spring assembly extends into the base and is fixedly connected to the displacement block. The displacement block is located inside the limiting block, and a limiting groove is provided on the bottom surface of the displacement block.
[0011] Preferably, a moving head is clamped in the limiting groove, and the moving head is fixedly connected to the clamping block. There are two clamping blocks, and a connecting head is provided at the center position of the two clamping blocks, and the connecting head is fixedly connected to the base.
[0012] Preferably, the thickness of the clamping block is greater than the length of the connecting head.
[0013] Preferably, two upper and lower shielding plates are fixedly connected to the front side of the connecting block.
[0014] (3) Beneficial effects
[0015] After adopting the above technical solution, the utility model has the following advantages compared with the existing technology: the utility model is a rapier loom sword opening device, which, by setting the card and the assembly, first pushes the handle inward so that the moving head moves outward along the limit groove, thereby causing the clamping block to expand outward, and then puts the end of the rapier on the connecting head, releases the handle, and returns to its original state under the recovery of the spring force of the spring assembly itself. At this time, the two clamping blocks clamp the sword head to complete the fixation of the sword head. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below through the accompanying drawings and examples.
[0023] like Figure 1-5As shown: A rapier loom sword opening device includes a rapier 1, the front end of the rapier 1 is connected to a connecting block 2, the front side of the connecting block 2 is connected to a rapier head 4, a card and assembly is provided in the rapier 1, the card and assembly includes a spring assembly 7, a clamping block 9, a connecting head 10, and a displacement block 14. The end of the rapier head 4 passes through the connecting block 2 and is sleeved on the connecting head 10. When the rapier head 4 is installed, the grip 3 is pressed inward, driving the connecting rod 5 and the spring assembly 7 to move inward, and then driving the displacement block 14 to move inward. At this time, during the movement of the displacement block 14, the connecting head 11 moves in the limit slot 12, driving the two clamping blocks 9 to move inward. Block 9 moves outward, and the sword head 4 is put on the connecting head 10, and then the handle 3 is released. A connecting plate with one end resisting the displacement block 14 connected to the spring assembly 7 is fixed in the base 15. When the handle 3 is pushed inward, this part of the spring is compressed. After release, the spring relaxes and pushes the connecting plate outward to restore to its original position, and the spring assembly 7 itself also relaxes from the compressed state to the natural state. The displacement block 14 and the spring assembly 7 return to their original state. After the limiting groove 12 moves outward to the initial state, the moving head 11 is located at the end of the limiting groove 12, and the two clamping blocks 9 firmly fix the sword head 4 inward.
[0024] One end of the spring assembly 7 is fixedly connected to the fixing plate 13, which is located inside the support plate 6. The other side of the fixing plate 13 is fixedly connected to the connecting rod 5, which is located outside the rapier 1 and has the handle 3 fixedly connected thereto.
[0025] The other end of the spring assembly 7 extends into the base 15 and is fixedly connected to the displacement block 14 through the connecting plate. A spring is also provided in the base 15, and the spring is opposite to the connecting plate. When the handle 3 is pushed inward, the spring assembly 7 drives the connecting plate to move inward, so that the displacement block 14 moves forward. At the same time, the spring is squeezed and contracted. After the handle 3 is released, the spring expands and pushes the displacement block 14 and the connecting plate back to their original position. The spring assembly 7 itself also expands to reset the entire structure. The displacement block 14 is located inside the limit block 8, and a limit groove 12 is provided on the bottom surface of the displacement block 14.
[0026] A moving head 11 is clamped in the limiting groove 12 , and the moving head 11 is fixedly connected to the clamping block 9 . There are two clamping blocks 9 , and a connecting head 10 is provided at the center of the two clamping blocks 9 . The connecting head 10 is fixedly connected to the base 15 .
[0027] The thickness of the clamping block 9 is greater than the length of the connecting head 10, so that the clamping block 9 will not fall out when clamping the rapier head 4.
[0028] An upper and lower shielding plates are fixedly connected to the front side of the connecting block 2 to protect the sword head 4.
[0029] The above description is based on the embodiments for inspiration. Through the above description, relevant personnel can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content of the specification, and its protection scope must be determined according to the scope of the claims.
