Description

Technical Field

[0001] This utility model relates to the field of crochet rope production technology, specifically a winding tension uniform adjustment device for crochet rope production. Background Technology

[0002] With people's pursuit of a perfect life and the rapid development of industry, ropes have changed from being twisted from several strands to being woven from two, three, or more strands, making the surface texture of the ropes increasingly delicate and beautiful. They can be woven together in a regular pattern of one or more colors, making the colors more attractive. Materials can include fibers such as hemp, palm fiber, polypropylene yarn, polyester yarn, cotton yarn, and nylon yarn, or metals, and they can be seen everywhere in life.

[0003] During the production of crocheted rope, excessive tension in the early stage (large spool diameter and fast thread speed) and relaxation in the later stage (small spool diameter and slow thread speed) result in uneven density and rough surface texture of the crocheted rope. In order to deal with this situation, it is necessary to frequently adjust the motor speed or guide wheel position manually, which is inefficient and relies on operating experience. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A winding tension uniform adjustment device for producing crocheted rope includes a winding mechanism and an adjustment mechanism. The winding mechanism includes a frame, a motor connected to the bottom of the inner cavity of the frame, a winding disc connected to the output shaft of the motor, and multiple movable pressure plates movably embedded in the top of the winding disc. The adjustment mechanism includes multiple sliding members that slide the top of the inner cavity of the frame, a pneumatic damper embedded in the outer end of the sliding member, a guide wheel frame connected to the movable end of the pneumatic damper, a pressure sensor connected to the inner wall of the guide wheel frame, a rod connected to the top of the sliding member, and a miniature electric push rod connected between the frame and the sliding member.

[0007] By adopting the above technical solution, after fixing the two ends of the fiber filament, the motor drives the winding disc to rotate, and multiple fiber filaments are evenly wound in a spiral trajectory. During the winding process, the diameter of the spool gradually decreases as the fiber filaments are consumed. The pressure sensor in the guide wheel frame detects the tension change in real time and transmits the data to the external PLC controller. The PLC analyzes the tension data based on a preset algorithm and executes two controls simultaneously: one is to calculate the extension and retraction of the micro electric push rod, drive the sliding part to move along the axial direction of the pneumatic damper, dynamically reduce the winding radius through the guide wheel frame, and maintain a constant linear speed; the other is to dynamically adjust the speed of the motor output shaft to further balance the tension fluctuation.

[0008] In a preferred embodiment, the present invention can be further configured as follows: multiple movable pressure plates are arranged in a ring with equal spacing, and the top of each movable pressure plate is integrally formed with a handle.

[0009] In a preferred embodiment, this utility model can be further configured such that multiple pressure sensors and multiple miniature electric actuators are electrically connected to an external PLC, and the motor is electrically connected to the external PLC.

[0010] In a preferred embodiment, the present invention can be further configured such that: the movable pressure plate is provided with a locking assembly, the locking assembly including a movable disc movably embedded in the top of the movable pressure plate and two limiting sleeves movably sleeved at both ends of the movable disc, the two limiting sleeves being fixedly connected to the top of the winding disc.

[0011] In a preferred embodiment, the present invention can be further configured such that the bottom of the movable disc is flush with the top of the winding disc, and a lever is fixedly connected to the top of the movable disc.

[0012] In a preferred embodiment, the present invention can be further configured such that: both inner side walls of the frame are fixedly connected to guide sleeves, and the winding disc is slidably connected between the two guide sleeves.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, after fixing the two ends of the fiber filament, the motor drives the winding disc to rotate, and multiple fiber filaments are evenly wound in a spiral trajectory. During the winding process, the diameter of the spool gradually decreases as the fiber filaments are consumed. The pressure sensor in the guide wheel frame detects the tension change in real time and transmits the data to the external PLC controller. The PLC analyzes the tension data based on a preset algorithm and executes two controls simultaneously: one is to calculate the extension and retraction of the micro electric push rod, drive the sliding part to move along the axial direction of the pneumatic damper, dynamically reduce the winding radius through the guide wheel frame, and maintain a constant linear speed; the other is to dynamically adjust the speed of the motor output shaft to further balance the tension fluctuation.

[0015] 2. In this invention, during the winding process of multiple fiber filaments, the instantaneous impact energy generated by start-stop or vibration is actively absorbed by the pneumatic damper through elastic deformation, and the system breakage rate is stably controlled below 1%.

The winding mechanism 100 includes a frame 110, a motor 120 connected to the bottom of the inner cavity of the frame 110, a winding disc 130 connected to the output shaft of the motor 120, and a plurality of movable pressure plates 140 movably embedded in the top of the winding disc 130.

[0031] The adjustment mechanism 200 includes multiple sliding members 210 that slide the top of the inner cavity of the frame 110, a pneumatic damper 220 embedded at the outer end of the sliding member 210, a guide wheel frame 230 connected to the movable end of the pneumatic damper 220, a pressure sensor 240 connected to the inner wall of the guide wheel frame 230, a rod 250 connected to the top of the sliding member 210, and a miniature electric push rod 260 connected between the frame 110 and the sliding member 210.

[0032] Furthermore, multiple pressure sensors 240 and multiple miniature electric actuators 260 are electrically connected to an external PLC, and the motor 120 is also electrically connected to the external PLC.

[0033] Furthermore, guide sleeves 400 are fixedly connected to both inner side walls of the frame 110, and the winding reel 130 is slidably connected between the two guide sleeves 400.

[0034] Example 2:

[0035] Combination Figure 1 , 2 and Figure 5 As shown, based on Embodiment 1, multiple movable pressure plates 140 are arranged in a ring with equal spacing, and the top of each movable pressure plate 140 is integrally formed with a handle.

[0036] Example 3:

[0037] Combination Figure 1 and Figure 5 As shown, in the above embodiment, the movable pressure plate 140 is provided with a locking assembly 300. The locking assembly 300 includes a movable disc 310 movably embedded in the top of the movable pressure plate 140 and two limiting sleeves 320 movably sleeved at both ends of the movable disc 310. Both limiting sleeves 320 are fixedly connected to the top of the winding disc 130.

[0038] Furthermore, the bottom of the movable disc 310 is flush with the top of the winding disc 130, and a lever is fixedly connected to the top of the movable disc 310.

[0039] Working principle and usage process of this utility model:

[0040] Fiber fixing: Insert the starting end of the fiber into the bottom of the movable pressure plate 140, press the movable pressure plate 140 down to the top of the winding disc 130 to complete the initial fixing, then pull the other end of the fiber around the outside of the guide wheel frame 230, and finally tie it tightly to the rod 250. Repeat this operation to complete the installation of all fiber filaments.

[0041] Winding Operation and Dynamic Adjustment: The start motor 120 drives the winding reel 130 to rotate, and multiple strands of fiber are wound evenly in a spiral trajectory.

Second, it dynamically adjusts the output shaft speed of the motor 120 to further balance the tension fluctuations.

[0042] Tension mutation suppression: The instantaneous impact energy generated during the winding process due to start-up, shutdown or vibration is actively absorbed by the pneumatic damper 220 through elastic deformation, and the system breakage rate is stably controlled below 1%.
