Detailed Implementation
[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] A wheel-type roller assembly for an ultrasonic lace sewing machine includes a wheel frame 2 and a mounting frame 1 disposed on the ultrasonic lace sewing machine. The mounting frame 1 is U-shaped. A sliding component is disposed between the mounting frame 1 and the wheel frame 2. The wheel frame 2 is slidably connected to the mounting frame 1 through the sliding component. The sliding component is driven to move by a cylinder 5 at the top of the mounting frame 1.
[0022] The wheel frame 2 has several sets of mounting slots 21. The inner walls of the mounting slots 21 are provided with clamping structures 4 on both sides. Rollers 3 are installed between two sets of clamping structures 4. The mounting slots 21 gradually decrease in size from the center of the wheel frame 2 outwards. The rollers 3 are adapted to the corresponding mounting slots 21.
[0023] The corresponding rollers 3 are installed between the two clamping structures 4. The rollers 3 are installed through the clamping structures 4 and are rotatably connected to the clamping structures 4. When the ultrasonic lace sewing machine is working, the fabric moves forward under the drive of the ultrasonic lace sewing machine, which causes the rollers 3 to rotate. There are multiple sets of rollers 3, which can ensure that the fabric moves in one direction and avoid the fabric shift during processing, which would affect the processing quality of the fabric. The clamping structures 4 can also be used to quickly and easily disassemble and replace the rollers 3, which reduces the difficulty of replacing the rollers 3 and improves the working efficiency of the ultrasonic lace sewing machine. At the same time, the rollers 3 of the corresponding specifications can be selected for installation according to the operation needs of the ultrasonic lace sewing machine, which can be adapted to the processing of various fabrics.
[0024] As a possible implementation of this solution, preferably, the clamping structure 4 includes a fixed clamping end 41 and a movable clamping end 42 disposed on both sides of the inner wall of the mounting groove 21. Multiple sets of balls 43 are disposed between the inner walls of the fixed clamping end 41 and the movable clamping end 42. A sliding plate 44 is disposed on the inner wall of the mounting groove 21 and slidably connected to both ends of the movable clamping end 42. A spring 45 is connected between the movable clamping end 42 and the side wall of the mounting groove 21.
[0025] The roller 3 has connecting shaft ends 31 at both ends, and the connecting shaft ends 31 have grooves 32 that are slidably connected to the ball bearings 43.
[0026] When roller 3 needs to be replaced, and the roller 3 needs to be disassembled and installed, by pulling the movable clamping end 42, the movable clamping end 42 slides along the slide plate 44 while squeezing the spring 45 to move away from the fixed clamping end 41, and the roller 3 to be replaced is removed. The connecting shaft end 31 of the new roller 3 is installed on the inner wall of the fixed clamping end 41, so that the slide groove 32 is installed with the ball 43. The movable clamping end 42 is slowly released, and under the action of the spring 45, the movable clamping end 42 moves along the slide plate 44 closer to the fixed clamping end 41, so that the ball 43 of the movable clamping end 42 moves in the direction of the slide groove 32. The fixed clamping end 41 and the movable clamping end 42 complete the installation of the new roller 3 from both sides. At the same time, the rotation of the roller 3 is ensured by the cooperation of the ball 43 and the slide groove 32, which improves the convenience of disassembling and replacing the roller 3.
[0027] As a possible implementation of this solution, preferably, the movable clamping end 42 includes a clamping plate 421 that abuts against the fixed clamping end 41. The clamping plate 421 has adjusting plates 422 at both ends, and the adjusting plate 422 has a rectangular groove 423 that is slidably connected to the slide plate 44.
[0028] When replacing the roller 3, by pulling the adjusting plate 422 at both ends of the clamping plate 421 or at one end of the clamping plate 421, the rectangular groove 423 on the adjusting plate 422 slides along the slide plate 44. At the same time, the clamping plate 421 compresses the spring 45, causing the clamping plate 421 to move away from the fixed clamping end 41. This makes it easier to remove the roller 3 that needs to be replaced and install the new roller 3 between the fixed clamping end 41 and the clamping plate 421. This enables quick disassembly and replacement of the roller 3, effectively reducing the difficulty of replacing the roller 3 and improving work efficiency.
[0029] As a possible implementation of this solution, preferably, the sliding assembly includes guide rails 11 disposed on both sides of the inner wall of the mounting frame 1, sliders 12 are slidably connected on the guide rails 11, two sets of sliders 12 are disposed and fixed on both sides of the wheel frame 2, a connecting rod 52 is disposed on the top of the slider 12, and a drive plate 51 is disposed on the two sets of connecting rods 52, and the drive plate 51 is fixedly connected to the drive end of the cylinder 5.
[0030] The cylinder 5 drives the drive plate 51 to move. The drive plate 51 is fixedly connected to the slider 12 through the connecting rod 52, so that the slider 12 drives the wheel frame 2 to move along the guide rail 11, thereby adjusting the position of the roller 3 on the wheel frame 2 to meet the needs of fabric processing and improve the quality of fabric operation.
[0031] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
