Description

Technical Field

[0001] This application relates to the field of air-jet looms, and more particularly to a waste edge winding mechanism for an air-jet loom. Background Technology

[0002] Water bath pre-expansion double-sided napping technology pre-expands the fabric substrate in a water bath environment, making the fiber structure more loose. Combined with a double-sided napping process, this significantly improves the nap density and uniformity of the fabric surface, enhancing its softness and feel, and meeting the market demand for high-end textile products. The aforementioned fabrics are typically produced using air-jet looms. Air-jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. Their working principle utilizes air as the weft insertion medium; the compressed airflow generates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion.

[0003] Currently, fabrics woven by air-jet looms will produce raw edges. Therefore, in order to improve the quality of the fabric, the equipment is usually equipped with a raw edge cutting device to cut off the raw edges of the fabric. This will produce waste edges, which are usually collected by a waste edge collection device.

[0004] The waste edge take-up mechanism of existing air-jet looms typically includes a frame and a take-up roller rotatably connected to the frame. The take-up roller rotates under the drive of the drive assembly, winding the waste edge around the surface to achieve take-up.

[0005] Regarding the aforementioned technologies, the take-up roller and the frame are mostly fixedly connected or connected by bolts. Operators need to manually disassemble the take-up roller to remove it from the frame, which is quite inconvenient. Utility Model Content

[0006] To facilitate the disassembly of the take-up roller, this application provides a waste edge take-up mechanism for an air-jet loom.

[0007] The waste edge winding mechanism for an air-jet loom provided in this application adopts the following technical solution: A waste edge take-up mechanism for an air-jet loom includes a frame and a take-up roller. The take-up roller is rotatably connected to the frame. One end of the take-up roller is rotatably connected to the frame via a cylinder, and the take-up roller is inserted into the cylinder. The frame is connected to a rotating assembly for driving the cylinder to rotate. A locking block is connected inside the cylinder. The take-up roller has a locking groove, and the locking block is inserted into the take-up roller through the locking groove. The cylinder is connected to a moving assembly for driving the locking block to insert into or disengage from the locking groove.

[0008] By adopting the above technical solution, during use, the rotating component drives the cylinder to rotate, and the locking block is inserted into the take-up roller through the locking groove, so that the take-up roller rotates synchronously with the cylinder to take up the waste edge; after the winding is completed, the moving component drives the locking block to disengage from the locking groove, and the take-up roller separates from the cylinder, thereby facilitating the disassembly of the take-up roller and improving the ease of operation.

[0009] Optionally, the moving component includes a push block, a drive member, and a reset member. The push block slides and engages with the cylinder. One end of the push block is provided with a first guide surface. The first guide surface is inclined and is used to contact the locking block. The first guide surface is used to guide the locking block closer to the locking groove. The drive member is used to drive the push block to move and push the locking block closer to the locking groove. The reset member is used to drive the locking block to move and push the locking block away from the locking groove.

[0010] By adopting the above technical solution, when in use, the driving component drives the pushing block to move, the guide surface contacts the locking block and guides the locking block to insert into the locking groove. When unlocking, the driving component drives the pushing block away from the locking block, and the reset component drives the locking block to disengage from the locking groove, thereby facilitating the disassembly and installation of the take-up roller.

[0011] Optionally, the reset element is a first spring, one end of which is connected to the locking block and the other end of which is connected to the cylinder. The first spring drives the locking block to move and moves the locking block away from the locking groove.

[0012] By adopting the above technical solution, when the locking block is inserted into the locking groove, the first spring deforms. When unlocking, after the block is pushed away from the locking block, the first spring returns to its shape and drives the locking block to disengage from the locking groove. Automatic reset is achieved by utilizing the spring force. The structure is simple and reliable, and the ease of operation is improved.

[0013] Optionally, the driving component includes a connecting ring and a first cylinder. The first cylinder is connected to the frame, the connecting ring is located at one end of the cylinder, the end of the pushing block away from the locking block is connected to the connecting ring, and the piston rod of the first cylinder is connected to the connecting ring.

[0014] By adopting the above technical solution, when in use, the piston rod of the first cylinder pushes the connecting ring to move, the connecting ring pushes the push block to slide, and the push block pushes the locking block to insert into the locking groove. In this way, the locking action is automated through pneumatic drive, further improving the convenience of operation.

[0015] Optionally, a second spring and a movable block are connected inside the cylinder. The length direction of the second spring is consistent with the length direction of the cylinder. One end of the second spring is connected to the inner wall of the cylinder, and the other end of the second spring is connected to the movable block. The movable block is in contact with one end of the take-up roller. The second spring is used to drive the movable block to slide and cooperate with the inner wall of the cylinder and drive the movable block to push the take-up roller away from the cylinder.

[0016] By adopting the above technical solution, when disassembling the take-up roller, after the locking block disengages from the locking groove, the second spring pushes the moving block to cause the take-up roller to pop outward, which makes it easier for operators to quickly remove the take-up roller and further improves the convenience of operation.

[0017] Optionally, the frame is connected to a collection box, the collection box having an opening at the top and being located below the take-up roller.

[0018] By adopting the above technical solution, the completed winding roller can be collected in the collection box, which facilitates subsequent processing by operators.

[0019] Optionally, the bottom of the collection box is equipped with wheels.

[0020] By adopting the above technical solution and adding rollers, the winding roller can be easily moved, thereby reducing the intensity of manual handling and improving work efficiency.

[0021] Optionally, the rotating assembly includes a first pulley, a second pulley, a belt, and a first motor. The first pulley is sleeved on the cylinder, the first motor is connected to the frame, the second pulley is connected to the output shaft of the first motor, one end of the belt is sleeved on the first pulley, and the other end of the belt is sleeved on the second pulley.

[0022] By adopting the above technical solution, when in use, the first motor drives the second pulley to rotate, the belt drive drives the first pulley and the cylinder to rotate, and then drives the take-up roller to rotate and take up the winding. Stable power transmission is achieved through belt drive, so that the take-up roller rotates at a uniform speed, driving the waste edge to wrap around the take-up roller.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, the rotating component drives the cylinder to rotate, and the locking block is inserted into the take-up roller through the locking groove, so that the take-up roller rotates synchronously with the cylinder to take up the waste edge; after the winding is completed, the moving component drives the locking block to disengage from the locking groove, and the take-up roller separates from the cylinder, which facilitates the disassembly of the take-up roller and improves the ease of operation. 2. In use, the driving component moves the pushing block, the guide surface contacts the locking block and guides the locking block to insert into the locking groove. When unlocking, the driving component moves the pushing block away from the locking block, and the reset component moves the locking block out of the locking groove, thereby facilitating the disassembly and installation of the take-up roller. 3. When disassembling the take-up roller, after the locking block disengages from the locking groove, the second spring pushes the moving block to cause the take-up roller to pop outward, making it easier for the operator to quickly remove the take-up roller and further improving the ease of operation.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a waste edge winding mechanism for an air-jet loom. (Refer to...) Figure 1 , Figure 2 and Figure 3 A waste edge take-up mechanism for an air-jet loom includes a frame 100, a cylinder 300, and a take-up roller 200. The cylinder 300 is horizontally positioned and rotatably connected to the frame 100. One end of the take-up roller 200 is inserted into the cylinder 300, and the cylinder 300 is sleeved on the take-up roller 200. The central axis of the take-up roller 200 is collinear with the central axis of the cylinder 300. A locking block 310 is connected inside the cylinder 300, and a locking groove 210 is formed on the circumference of the take-up roller 200. The locking block 310 is inserted into the take-up roller 200 through the locking groove 210. A moving component 400 is connected to the cylinder 300. The moving component 400 is used to drive the locking block 310 to insert into or disengage from the locking groove 210. The moving component 400 can drive the locking block 310 to move and drive the locking block 310 to insert into or disengage from the locking groove 210, thereby facilitating the assembly and disassembly of the take-up roller 200 and improving operational portability.

The driving component 420 includes a connecting ring 421 and a first cylinder 422. The length direction of the first cylinder 422 is consistent with the length direction of the cylinder 300, and the piston rod of the first cylinder 422 is connected to one end of the connecting ring 421. The connecting ring 421 is located at the end of the cylinder 300 away from the take-up roller 200, and the central axis of the connecting ring 421 is collinear with the central axis of the cylinder 300. The end of the pushing block 410 away from the locking block 310 is connected to the end of the connecting ring 421 near the cylinder 300, and the pushing block 410 slides circumferentially along the cylinder 300 in cooperation with the connecting ring 421.

[0035] Reference Figure 3 and Figure 4 A connecting groove 321 is formed on the inner wall of one end of the moving groove 320 along the width direction of the sliding groove 330. The length direction of the connecting groove 321 is consistent with the length direction of the moving groove 320. A limiting block 311 is connected to one end of the locking block 310 along the width direction of the sliding groove 330. The limiting block 311 slides and engages within the connecting groove 321 along the length direction of the connecting groove 321.

One end of the first spring 430 is connected to the limiting block 311, and the other end is connected to the inner wall of the connecting groove 321. The first spring 430 drives the locking block 310 to move and drive it away from the locking groove 210. When disassembling the take-up roller 200, the first cylinder 422 drives the connecting ring 421 to move, the push block 410 moves with the connecting ring 421, and the push block 410 moves away from the locking block 310. The first spring 430 drives the locking block 310 to disengage from the locking groove 210, thereby facilitating the disassembly of the take-up roller 200.

[0036] Reference Figure 3 A second spring 340 and a movable block 350 are connected inside the cylinder 300.

[0038] The implementation principle of the waste edge take-up mechanism of an air-jet loom according to an embodiment of this application is as follows: After take-up is completed, the piston rod of the first cylinder 422 retracts, driving the connecting ring 421 to move away from the take-up roller 200. The connecting ring 421 drives the push block 410 to move. At this time, the first spring 430 returns to its shape and drives the limiting block 311 to slide and engage with the inner wall of the connecting groove 321. The locking block 310 moves with the limiting block 311, causing the locking block 310 to disengage from the locking groove 210, and the take-up roller 200 and the cylinder 300 are unlocked. After the lock is released, the second spring 340 returns to its shape and pushes the moving block 350 to move along the length direction of the cylinder 300. The moving block 350 pushes the take-up roller 200 to move, causing the take-up roller 200 to automatically disengage from the cylinder 300, thereby facilitating the disassembly of the take-up roller 200 and improving the ease of operation.
