Description

Technical Field

[0001] This utility model belongs to the field of fabric winding technology, and more specifically, it relates to an automatic tensioning fabric winding roller. Background Technology

[0002] In the fabric production process, the winding process is a crucial step. During fabric winding, an automatic tensioning fabric winding roller is typically used. Existing automatic tensioning fabric winding rollers usually consist of a winding roller, a sensor, a drive mechanism, and an adjustment mechanism. The drive mechanism typically uses a servo motor as a power source, which drives the winding roller to rotate via a transmission device, thus achieving fabric winding. A tension sensor collects tension data of the fabric in real time during operation and transmits the signal to a controller. When the tension signal received by the controller deviates from the preset value, the adjustment mechanism adjusts the servo motor speed, thereby achieving closed-loop control of the fabric tension.

[0003] Existing application number CN202322534673.2 discloses a guide roller for a winding machine, comprising a guide roller; the guide roller is hollow inside, and grooves are provided around both ends of the outer side of the guide roller. A bidirectional lead screw is rotatably mounted at both ends of the guide roller, and a lead screw nut is rotatably mounted on the outer side of both ends of the bidirectional lead screw. A baffle is mounted on the upper end of the lead screw nut, and the baffle extends outward through the grooves from the outer side of the guide roller. Both ends of the guide roller are rotatably mounted on the upper side of a crossbeam. A tension adjusting mechanism is mounted on one side of the crossbeam, and an installation groove is mounted on the outer side of the tension adjusting mechanism. A sliding rod is installed inside the installation groove, and a slider is slidably mounted on the outer side of the sliding rod. In this invention, during the rotation of the bidirectional lead screw, the baffles are moved by the action of the lead screw nut, thereby adjusting the distance between the baffles according to the width of the material. Simultaneously, during the material transmission process of the guide roller, the tension of the guide roller is adjusted by the tension adjusting mechanism.

[0004] Based on the above, most existing automatic tensioning fabric take-up rollers have smooth surfaces, making it very inconvenient to fix them when the fabric starts, and loosening often occurs. Currently, the fabric ends are usually fixed with glue, but glue fixation leaves marks that affect the fabric quality. Moreover, the drive and guide structure of the take-up roller relies on the bushings and gears at both ends. When the take-up roller needs to be frequently disassembled and replaced, lubrication and maintenance are required to maintain the smoothness of the gears and bushings to avoid rotation jamming caused by friction wear, making the operation quite cumbersome. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic tensioning fabric take-up roller. This solves the problem that existing automatic tensioning fabric take-up rollers often have smooth surfaces, making them inconvenient to secure at the beginning of fabric operations, frequently resulting in loosening. Currently, the fabric ends are typically secured with glue, but this leaves marks that affect fabric quality. Furthermore, the drive and guiding structure of the take-up roller relies on bushings and gears at both ends. When the take-up roller needs frequent disassembly and replacement, lubrication and maintenance are required to maintain the smooth operation of the gears and bushings, preventing rotational jamming due to frictional wear, making operation cumbersome.

The two pairs of transmission links are respectively slidably connected inside the two pairs of sliding rods.

[0011] Furthermore, the maintenance component includes: a drive rack, a threaded rod, and a driven gear. The drive rack is provided in two sets, and the two sets of drive racks are respectively fixedly installed on one side of the two sets of transmission blocks. The threaded rod is provided in two sets, and the two sets of threaded rods are rotatably connected inside the two sets of oil storage tanks. The driven gear is provided in two sets, and the two sets of driven gears are fixedly installed on the top of the two sets of threaded rods. The drive rack and the driven gear mesh with each other.

[0012] Furthermore, the maintenance component also includes: a limiting mechanism, a transmission piston, a connector, and lubrication holes.

[0016] Secondly, this invention features a maintenance component that, through the mechanical linkage between the clamping action and the lubrication system, transforms the fabric clamping process into lubricating oil compression power. When the fixed clamping plate closes, the drive rack rotates the driven gear, and the threaded rod drives the transmission piston to compress the lubricating oil, which is then transported through a pipeline to the lubrication holes between the drive gear and the guide sleeve, achieving lubrication before winding. The limiting mechanism ensures that oil is supplied only during winding, avoiding oil waste. Furthermore, a trigger switch and speaker within the oil tank form an intelligent early warning system that automatically alarms when the lubricating oil level is insufficient, transforming the traditional periodic manual maintenance of the equipment into intelligent, on-demand lubrication.

[0017] This utility model has the advantages of quick fixing, convenient maintenance, and timely prompts. It facilitates quick clamping of the fabric ends, and when the fixing clip is closed, it lubricates the drive gear and guide bushing, which greatly improves the maintenance and lubrication efficiency.

[0037] Example 2:

[0038] Based on Example 1, such as Figures 1 to 8 As shown, it also includes a maintenance component, which is disposed inside the take-up roller 1.

[0039] The maintenance components include: a drive rack 506, a threaded rod 701, and a driven gear 702.

[0041] The maintenance components also include: a trigger switch 705 and a speaker 101.

The trigger switches 705 and speakers 101 are connected together by wiring harness and power supply to form a switching circuit.

[0042] The specific usage and function of this embodiment are as follows:

[0043] When the fixed clamping piece 6 performs the fabric end clamping action, the transmission block 503 moves laterally in sync, and the drive rack 506 fixed on its side moves in conjunction. The drive rack 506 drives the driven gear 702 to rotate through the meshing teeth, which in turn drives the threaded rod 701 to rotate inside the oil tank 7. The rotational motion of the threaded rod 701 is converted into the axial displacement of the transmission piston 704 through the threaded pair, causing the piston to squeeze lubricating oil along the inner wall of the oil tank 7. The pressurized lubricating oil is introduced into the pipeline through the connector 706, and finally seeps out from the lubrication hole 301 inside the drive gear 3 and the guide bushing 4, achieving precise lubrication of the transmission components.

[0044] The limiting mechanism 703 adopts a ratchet and pawl one-way locking structure. When the fixed clamp 6 is closed, the drive rack 506 drives the threaded rod 701 to rotate in the forward direction; when the fixed clamp 6 is open, the drive rack 506 moves in the reverse direction, triggering the ratchet to idle, preventing the threaded rod 701 from driving the transmission piston 704 to reset. This design ensures that lubricating oil is squeezed out only as needed during the clamping stage of fabric winding, avoiding oil waste during no-load operation.

[0045] When the transmission piston 704 moves to the critical position at the bottom of the oil tank 7, its end face presses against the trigger switch 705 on the inner side, and the speaker 101 emits a sound through the switch circuit to prompt the staff to take out the oil tank 7 in time to add lubricating oil.
