Description

Technical Field

[0001] The utility model relates to the technical field of textile printing and dyeing, in particular to a cloth winding roller with an anti-falling-out structure. Background Art

[0002] The cloth roller is an important accessory used in circular knitting machines. It is usually installed at the bottom of the circular knitting machine and is used to reel in and divide the woven fabric. During reeling, the fabric may be unevenly distributed on the cloth roller, causing the weight of one end of the cloth roller to be greater than the weight of the other end, causing one end of the cloth roller to tilt or even move out of its original position, causing the cloth roller to stop.

[0003] For example, publication number CN217948421U discloses a cloth roller anti-escape device and a circular knitting machine. The device cooperates with a connecting guide block connected to the end of the cloth roller through a sliding groove and an avoidance groove, so that the cloth roller can be floated on the frame; because the size of the connecting guide block is larger than the size of the avoidance groove.

[0004] However, the practicality of this fixed structure is poor. When it is subsequently disassembled, the entire device needs to be disassembled, which is troublesome when replacing the rotating roller. In addition, the device cannot adjust the height of the rotating roller, resulting in poor practicality of the device. In view of this, we propose a cloth rolling roller with an anti-escape structure. Utility Model Content

[0005] The purpose of the present utility model is to provide a cloth winding roller with an anti-falling structure to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a cloth winding roller with an anti-slip structure, comprising a frame, a connecting cylinder provided on the side wall of the frame, a rotating roller provided on the side wall of the connecting cylinder, an inner wall of the connecting cylinder being rotatably connected to a rotating cylinder via a bearing, a fixing structure provided inside the rotating cylinder, and the fixing structure comprising:

[0007] A fixed plate, the fixed plate is fixedly mounted on the inner wall of the end of the rotating roller, the upper and lower sides of the fixed plate are slidably connected to sliding blocks, the side wall of the fixed plate is penetrated by an extrusion rod, the end of the extrusion rod is fixedly mounted with a pressure plate, both sides of the pressure plate are hinged with one end of a connecting strip, the other end of the connecting strip is hinged to the side wall of the sliding block, and an extrusion spring is wound around the surface of the extrusion rod;

[0008] The limit block is fixedly installed on the side wall of the sliding block, and two groups of positioning holes are opened on the inner wall of the end of the rotating roller. The limit block is located inside the positioning hole, and two groups of limit holes are opened on the inner wall of the rotating cylinder. Both sides of the end of the limit block are provided with installation grooves, and one end of the limit spring is fixedly installed on the inner wall of the installation groove, and a T-shaped block is fixedly installed on the other end of the limit spring. The inner wall of the connecting cylinder is slidably connected to a trapezoidal extrusion block, and an adjustment structure is provided inside the frame.

[0009] Preferably, the adjustment structure includes a sliding rod fixedly mounted on the inner wall of the frame, a sleeve is slidably connected to the surface of the sliding rod, the side wall of the sleeve is fixedly connected to the side wall of the connecting tube, a moving rod is passed through both sides of the inner wall of the connecting tube, an inclined baffle is fixedly mounted on one end of the moving rod, a limiting plate is fixedly mounted on the other end of the moving rod, and a reset spring is provided on the surface of the moving rod.

[0010] Preferably, sliders are slidably connected to both sides of the inner wall of the connecting tube, anti-skid plates are fixedly installed on the ends of the sliders, two sets of bayonets are provided at the connection between the connecting tube and the sleeve, one end of the connecting rod is hinged to the upper end of the slider, and the other end of the connecting rod is hinged to the lower end of the inclined baffle.

[0011] Preferably, one end of the return spring is fixedly connected to the side wall of the limiting plate, and the other end of the return spring is fixedly connected to the side wall of the connecting tube.

[0012] Preferably, the anti-skid plate is located inside the bayonet and contacts the surface of the slide bar. The movement of the anti-skid plate causes static friction with the surface of the slide bar, thereby fixing the sleeve for use.

[0013] Preferably, one end of the trapezoidal extrusion block contacts the inclined baffle, and the other end of the trapezoidal extrusion block contacts the side wall of the pressure plate.

[0014] Compared with the prior art, the present invention provides a cloth rolling roller with an anti-fall-out structure, which has the following beneficial effects:

[0015] 1. The cloth winding roller with an anti-slip structure is convenient for connecting the rotating roller and the rotating drum by setting a fixed structure. When installing the rotating roller, the user only needs to insert the end of the rotating roller into the inside of the rotating drum for connection. At this time, the rotating roller moves and the pressure plate on its inner wall will first contact the side wall of the trapezoidal extrusion block. At this time, the pressure plate will move through the extrusion rod. As the pressure plate squeezes the extrusion spring, the pressure plate will cause the trapezoidal extrusion block to move. During this process, the slider and the limit block on the inner wall of the fixed plate will move relative to each other and be inserted into the limit port, and then be clamped with the side wall of the limit port through the T-shaped clamping block, thereby completing the connection between the rotating roller and the rotating drum.

[0016] 2. The cloth winding roller with an anti-slip structure is conveniently adjusted to the position of the rotating roller by setting an adjustment structure. The user can change the position of the connecting tube by moving the sleeve on the surface of the slide rod. The position of the connecting tube is changed to change the position of the rotating roller subsequently inserted therein. The inclined pressure block is moved inward to squeeze the two sets of inclined baffles, so that the two sets of sliders and the anti-slide plate move downward to jam the slide rod, so that the slide tube cannot slide but is self-limited, thereby adjusting the position of the connecting tube and the rotating roller.

When the locking cam 310 is in the unlocked position, the locking cam 311 is unlocked and the locking cam 312 is unlocked, so that the locking cam 310 is unlocked and the locking cam 312 is unlocked.

[0028] Please continue reading Figure 1-Figure 7The adjustment structure 4 includes a slide rod 41 fixedly mounted on the inner wall of the frame 1, and a sleeve 42 is slidably connected to the surface of the slide rod 41. The side wall of the sleeve 42 is fixedly connected to the side wall of the connecting tube 2. A moving rod 43 is passed through both sides of the inner wall of the connecting tube 2. An oblique baffle 44 is fixedly mounted on one end of the moving rod 43, and a limit plate 45 is fixedly mounted on the other end of the moving rod 43. A return spring 46 is provided on the surface of the moving rod 43. Sliders 47 are slidably connected to both sides of the inner wall of the connecting tube 2, and an anti-slip Plate 48, two sets of bayonet holes are opened at the connection between the connecting tube 2 and the sleeve 42, the upper end of the slider 47 is hinged with one end of the connecting rod 49, the other end of the connecting rod 49 is hinged with the lower end of the oblique baffle 44, one end of the return spring 46 is fixedly connected to the side wall of the limit plate 45, the other end of the return spring 46 is fixedly connected to the side wall of the connecting tube 2, the anti-slip plate 48 is located inside the bayonet hole and contacts the surface of the slide rod 41, one end of the trapezoidal extrusion block 311 contacts the oblique baffle 44, and the other end of the trapezoidal extrusion block 311 contacts the pressure plate When the cam 42 is in contact with the side wall 34, the adjustment structure 4 is provided to facilitate the adjustment of the position of the rotating roller 5. The user can change the position of the connecting cylinder 2 by moving the sleeve 42 on the surface of the slide rod 41, and change the position of the rotating roller 5 inserted therein by changing the position of the connecting cylinder 2. During the connection between the rotating cylinder 6 and the rotating roller 5, when the pressure plate 34 can no longer move, the trapezoidal extrusion block 311 is moved on the inner wall of the connecting cylinder 2. At this time, when the inclined baffle 44 is squeezed, it will move relatively outward to both sides. The movement of the inclined baffle 44 will drive the moving rod 43 to move and stretch the return spring 46. At this time, the movement of the inclined baffle 44 drives the connecting rod 49 to move, and the movement of the connecting rod 49 drives the two sets of sliders 47 and anti-slide plate 48 hinged thereto to move inward to jam the surface of the slide rod 41, so that the sleeve 42 cannot slide but is self-limited, thereby improving the practicality of the device.

[0029] When working, the user can place the frame 1 steadily, and then move the sleeve 42 on the surface of the sliding rod 41 to change the position of the connecting tube 2, and then the end of the rotating roller 5 can be inserted and connected with the inside of the rotating tube 6. As the rotating roller 5 moves, the pressure plate 34 on its inner wall will first contact the side wall of the trapezoidal extrusion block 311. As the rotating roller 5 continues to move, the pressure plate 34 will move through the extrusion rod 33 on its side wall and squeeze the extrusion spring 333. As the pressure plate 34 squeezes the extrusion spring 333 to the limit position, the pressure plate 34 can no longer move, thereby allowing the trapezoidal extrusion block 311 to move on the inner wall of the connecting tube 2. In this process, the sliding block 32 and the limit block 36 on the inner wall of the fixed plate 31 will move relative to each other and be inserted into the limit opening 37. At this time, as the upper end of the limit block 36 disengages from the limit opening 37, the T-shaped block 310 is no longer squeezed by the inner wall of the positioning opening, so that the T-shaped block 3 When the lever 42 is in the unlocked position, the two sets of sliders 47 and the anti-skid plate 48 are moved inwards to lock the surface of the slider 41, so that the sleeve 42 cannot slide but is self-limited. When disassembling, the user only needs to press the two sets of T-shaped blocks 310 into the interior of the device groove 38 to release the limit of the T-shaped blocks 310 and the limiting opening 37, and then the user can directly pull out the rotating roller 5.

[0030] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
