Description

Technical Field

[0001] This application relates to the field of rib knitting machines, and more particularly to a quick-release rib knitting machine. Background Technology

[0002] The rib knitting machine is a special type of double-sided circular knitting machine, which can be used to knit collars, cuffs, laces, and hems.

[0003] Currently, Chinese utility model patent CN215328637U discloses a high-speed double-sided ribbing machine for textile processing, including a base and a threading machine body. The upper end of the base, located below the threading machine body, is equipped with a winding assembly. The winding assembly includes symmetrically arranged columns, with symmetrical rotating disks between the columns. The rotating disks are movably connected to the columns via shafts, one of which is connected to a stepper motor. Rotary drums are arranged in a circular array between the rotating disks. Large gears are fixedly mounted on both ends of the rotating drums, and the sides of the large gears are rotatably connected to the rotating disks via movable components. A motor lifting device is installed on the side of the columns, and a motor is installed inside the lifting device. The output end of the motor is connected to a small gear. A cutting groove plate is fixedly connected between the rotating disks, and a cutting assembly is provided at corresponding positions on the cutting groove plate. The cutting assembly is connected to the columns via a U-shaped frame. This application has the effect of improving work efficiency.

[0004] After the fabric is finished being rolled up, a new drum needs to be replaced. Since the drum is fixed to the rotating rod by a threaded rod, the threaded rod needs to be unscrewed and removed each time it is replaced, which is quite cumbersome. Utility Model Content

[0005] In order to improve the speed of drum replacement and thus improve the working efficiency of the equipment, this application provides a quick-release rigging machine.

[0006] This application provides a quick-release thread-pressing machine, which adopts the following technical solution:

[0007] A quick-release ribbing machine includes a ribbing machine body, a rotating frame, a winding assembly, and a rotating drum. The rotating frame is rotatably connected to the ribbing machine body. The winding assembly includes two rotating disks and a driving component. The rotating disks are rotatably connected to the rotating frame. A slot is formed on the side wall of each rotating disk, extending radially along the rotating disk. The rotating drum is engaged within the slot. A limiting component is provided on each rotating disk, including a limiting plate, a first magnet, and a second magnet. The limiting plate is rotatably connected to the rotating disk. The first magnet is disposed on the limiting plate, and the second magnet is disposed on the rotating disk. When the first magnet and the second magnet attract each other, the limiting plate abuts against the side wall of the rotating drum. The driving component drives the two rotating disks to rotate at the same speed.

[0008] By adopting the above technical solution, when the rotating drum needs to be replaced, the operator can first rotate the limiting plate by overcoming the magnetic force of the first and second magnets. At this time, the slot is exposed, and the operator can remove the rotating drum from the rotating disk. Then, the operator inserts the new rotating drum into the slot and rotates the limiting plate. The limiting plate abuts against the side wall of the rotating drum through the first and second magnets, restricting the rotation of the rotating drum relative to the rotating disk. The driving component drives the two rotating disks to rotate at the same speed, so that the two slots are always aligned. This makes it easier for the operator to remove the rotating drum after the fabric is wound, improving the speed of rotating drum replacement and thus improving the working efficiency of the equipment.

[0009] Optionally, the driving component includes two first driving gears, two second driving gears, and a driving motor. The two first driving gears correspond to two rotating disks. The first driving gears are disposed on the rotating disks. The two second driving gears correspond to the two first driving gears. The second driving gears are rotatably connected to the rotating frame. The second driving gears mesh with the corresponding first driving gears. The driving motor is used to drive the two second driving gears to rotate.

[0010] By adopting the above technical solution, the drive motor drives two second drive gears to rotate simultaneously, the two second drive gears drive two first drive gears to rotate, and the two first drive gears drive two rotating disks to rotate. Through the limiting of the slot and the rotating drum, the rotation of the rotating disk can drive the rotation of the rotating drum. The drive component has a simple structure and reduces the occurrence of different rotation speeds of the two rotating disks.

[0011] Optionally, the limiting plate is provided with a toggle block.

[0012] By adopting the above technical solution, the toggle block on the limit plate makes it easier for workers to rotate the limit plate, thus improving the disassembly efficiency of the rotating drum.

[0013] Optionally, the rotating drum is provided with a clamping member for clamping the fabric. The clamping member includes a clamping plate and a coil spring. The side wall of the rotating drum is provided with a clamping groove. The clamping plate is rotatably connected to the clamping groove. The coil spring is used to keep the clamping plate abutting against the fabric in the clamping groove.

[0014] By adopting the above technical solution, after the new drum is installed on the rotating plate, the end of the fabric needs to be installed on the clamping device. The operator overcomes the elasticity of the coil spring to rotate the clamping plate, so that the clamping groove is exposed, and the end of the fabric is placed in the clamping groove. Then the clamping plate is released. At this time, the clamping plate enters the clamping groove under the action of the coil spring, thereby realizing the state in which the clamping plate holds the fabric in the clamping groove.

[0015] Optionally, the clamping plate is provided with a pressing groove to facilitate pressing by the user.

[0016] By adopting the above technical solution, when the clamping plate is located in the clamping groove, the clamping plate and the rotating cylinder are on the same plane. By pressing the groove, it is convenient for the operator to lift one end of the clamping plate, which improves the convenience of clamping plate operation.

[0017] Optionally, the rotating frame is further provided with a tensioning element for tensioning the fabric. The tensioning element includes two tensioning rollers, a tensioning frame, and a torsion spring. The tensioning frame is rotatably connected to the rotating frame. The two tensioning rollers are parallel to each other and are rotatably connected to the tensioning frame. The torsion spring is used to limit the rotation of the tensioning frame.

[0018] By adopting the above technical solution, the fabric needs to be tensioned before it is rolled up, so as to reduce the wrinkles of the fabric. The fabric passes through two tensioning rollers in sequence, and the tensioning frame will rotate under the drive of the torsion spring. The tensioning frame will drive the tensioning roller to rotate around the torsion spring, so that the fabric is in a tensioned state.

[0019] Optionally, the rotating frame is further provided with an adjusting component, which includes two adjusting plates and two adjusting cylinders. The adjusting plates are slidably connected to the rotating frame along the length direction of the tension roller, and the two adjusting cylinders correspond to the two adjusting plates. The adjusting cylinders are used to drive the adjusting plates to move.

[0020] By adopting the above technical solution, the adjusting component is used to limit the two ends of the fabric width direction, so as to improve the neatness of the fabric roll-up. The operator adjusts the extension length of the adjusting cylinder piston rod according to the width of the fabric, thereby changing the distance between the two adjusting plates, so that the adjusting plates abut against the two ends of the fabric width direction.

[0021] Optionally, the drive unit may be provided with a protective cover.

[0022] By adopting the above technical solution, since the ribbing machine produces a large amount of lint and the drive component has a precise structure, the contact between the drive component and the lint can be reduced by using a protective cover.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The slot on the rotating disk is used to accommodate the rotating drum. The attraction between the first magnet and the second magnet enables the limiting plate to abut against the side wall of the rotating drum, realizing quick installation of the rotating drum and improving the installation efficiency of the rotating drum.

[0025] 2. The clamping component is used to fix the end of the fabric to the rotating drum, reducing the movement of the fabric relative to the rotating drum;

[0026] 3. Tensioners are used to tension the fabric before winding, thereby improving the quality of the fabric winding. Attached Figure Description
