Technical Field

[0001] The utility model relates to the technical field of textile processing, in particular to a warp beam brake device for an air jet loom. Background Art

[0002] The warp beam of the air jet loom is used to transport the warp thread during the weaving process. When the equipment stops, the warp beam may rotate in the opposite direction due to the reverse pulling of the fabric or other external forces, which will cause the wool threads of the fabric to be arranged unevenly, thus affecting the product quality. The warp beam brake can prevent the warp beam from rotating in the opposite direction when the equipment stops, thereby ensuring product quality.

[0003] The existing Chinese patent with announcement number CN214736493U discloses an automatic brake device for a warp beam, in which a supporting bearing seat is installed on the rectangular blocks of the machine head and the machine tail to support the warp beam, one or more warp heads are fixedly installed on the warp beam through a warp beam clamp, and a brake disc is installed at the outer end of the machine head of the warp beam through a key connection and a fastening pin, and a pneumatic disc brake is installed under the brake disc. The braking control is flexible, avoiding the incoordination of yarn movement during the warp feeding and loop starting and braking processes, ensuring the stability of the warp tension, and being able to adapt to warp knitting machine equipment with high speed performance.

[0004] Based on the above situation, the inventors believe that the brake pads are prone to wear when the brake device is currently in use, and traditional brake pads are often fixed to the support members by connecting parts such as bolts, which is inconvenient during loading and unloading.

[0035] The utility model embodiment specifically provides a jet loom warp beam brake device, please refer to Figure 1 , including a mounting plate 1 and a brake assembly 2.

[0036] Among them, a push cylinder 11 and a brake assembly 2 are fixedly provided on the mounting plate 1. The piston rod of the push cylinder 11 is connected to the brake assembly 2 so that the warp beam is braked through the brake assembly 2, so that the brake assembly 2 can be displaced to meet the braking needs.

[0037] Specifically, the brake assembly 2 is symmetrically arranged on the mounting plate 1, and the brake assembly 2 includes a brake frame 3, an elastic component 4, a brake pad 5 and a fixing component 6. The outer side of the brake frame 3 is fixed to the mounting plate 1 by the elastic component 4, and the brake pad 5 is kept in contact with the inner side of the brake frame 3. The brake frame 3 and the brake pad 5 are detachably fixed by the fixing component 6. The outer wall of the brake frame 3 is fixed to the piston rod of the push cylinder 11, so that when the warp axis a rotates, the push cylinder 11 can push the brake frame 3 to approach the warp axis a, so that the brake pad 5 and the warp axis a are pressed against each other for braking. The middle parts of the brake frame 3 and the brake pad 5 are both arc structures matching the outer surface of the warp axis a, so that they can be pressed against the warp axis a.

[0038] For further information, please refer to Figure 2 and Figure 3The elastic component 4 includes a cylinder 41, a slide rod 42, a first spring 43 and a guide groove 44. The outer side of the cylinder 41 is fixedly connected to the mounting plate 1, and the slide rod 42 is slidably installed inside the cylinder 41. The end of the slide rod 42 away from the cylinder 41 is fixed to the brake frame 3. The two ends of the first spring 43 are respectively fixedly connected to the cylinder 41 and the slide rod 42. The first spring 43 is located inside the cylinder 41, so that when the brake frame 3 is moved by thrust, the slide rod 42 can move synchronously and pull the first spring 43 to extend, so that the first spring 43 generates a rebound force, which is convenient for resetting the brake frame 3.

[0039] The guide groove 44 is provided at the outer side of the slide bar 42 , and the fixing assembly 6 is guided to move through the guide groove 44 .

[0040] During implementation, a slot 31 is provided on the front side of the brake frame 3 , and the slot 31 is used to provide an installation space for the fixing component 6 .

[0041] Specifically, the fixing component 6 includes a connecting piece 61, an assembly piece 62 and an insertion rod 63.

[0046] The positioning assembly includes a positioning rod 615, a convex plate 616 and a second spring 617. The positioning rod 615 is disposed in the mounting groove 613, and the outer wall of the positioning rod 615 is slidably connected to the ring 611, and the top of the positioning rod 615 is plugged into the positioning hole 614, so that the positioning rod 615 can slide up and down and be plugged into or separated from the positioning hole 614;

[0047] The boss 616 is fixedly arranged outside the positioning rod 615, and the boss 616 is connected to the mounting groove 613 via a second spring 617, so that when the positioning rod 615 moves downward, the boss 616 can compress the second spring 617 to facilitate the elastic reset of the positioning rod 615.

[0048] During implementation, a push block 618 is fixed to the bottom end of the positioning rod 615, and the positioning rod 615 is pulled down by the push block 618 to make it move up and down on the ring 611 and separate from the positioning hole 614. When the brake pad 5 needs to be removed, the positioning rod 615 can be separated from the positioning hole 614 first, and then the ring 611 can be slid outward to separate the insertion rod 63 from the insertion tube 621, and then the brake pad 5 can be conveniently pushed forward out of the slot 31. When installing, the insertion tube 621 is inserted into the slot 31, and the insertion rod 63 is reset and plugged into it. The operation is simple and can effectively improve the maintenance and replacement efficiency.

[0049] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
