[0002] The carding roller, namely the carding cylinder, is a spiny round rod, which is mainly used for carding and impurity removal. The fiber and impurities are separated by the carding method. The working principle of the carding cylinder is to use the spines or needle teeth on it to card the fiber flow. Through this carding process, the fiber and impurities are separated, so as to achieve the purpose of impurity removal.

[0003] A special fixture for a carding roller with the publication number of CN208729202U in the prior art has a relatively large structure and cannot be directly installed on the carding roller equipment for use. Therefore, additional space is required to place the device, which increases the occupied space. Moreover, when the device is in use, the fixing part clamps and fixes the surface of the carding roller. However, when the carding roller is in a rotating state during operation, there is a certain gap between the carding roller and the clamping component, resulting in unstable clamping. The carding roller is prone to smooth movement on the device, easily damaging the burrs of the carding roller, and excessive force during the clamping process is likely to cause scratches on the surface of the carding roller.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, the present utility model provides a technical solution: a special fixture for a barbed roller to prevent pinching marks. The fixture is clamped at both ends of the barbed roller 1 and includes two support plates 2. The two support plates 2 are distributed at both ends of the barbed roller 1. The ends of the two support plates 2 are respectively provided with a first mounting plate 3 and a second mounting plate 12. The first mounting plate 3 is T-shaped, and the second mounting plate 12 is L-shaped. An electric sliding table 13 is fixedly connected to the first mounting plate 3, and the slider of the electric sliding table 13 is fixedly connected to the adjacent support plate 2. Through holes are formed in both support plates 2, and a fixing mechanism is arranged in the through holes. The rotating shafts at both ends of the barbed roller 1 respectively pass through the adjacent through holes.

[0024] According to the overall structure of the device, the support plates 2 are symmetrically installed on the barbed roller 1 device through the first mounting plate 3 and the second mounting plate 12. The electric sliding table 13 is started to move the support plate 2 on this side, increasing the distance between the two support plates 2 to facilitate the barbed roller 1 to be placed between the two support plates 2, and then the support plate 2 is moved back to its original position, so that the rotating shafts at both ends of the barbed roller 1 are inserted into the adjacent through holes, and the rotating shafts are fixed through the fixing mechanism, thereby clamping and fixing the barbed roller 1, and at the same time, it can be suitable for the installation of barbed rollers 1 of different lengths.

[0025] As shown Figure 2 in Figure Figure 2 , the support plate 2 is composed of a fixed plate 201 and a moving plate 202 that are fitted together. The fixed plate 201 is fixedly connected to the mounting plate. The cross-section of the fixed plate 201 is in a U-shape. Sliding grooves are provided at both the top and bottom of the fixed plate 201. Screws 203 are fixedly connected to both the top and bottom of the moving plate 202. The screws 203 pass through the adjacent sliding grooves and are threadedly connected to nuts.

[0026] By turning the nuts to loosen them, the moving plate 202 can be moved outwards, so that the length of the support plate 2 can be adjusted. Thereby, the distance between the axis of the barbed roller 1 and the equipment can be adjusted, and barbed rollers 1 of different thicknesses can be installed.

[0027] As shown Figure 2 in Figures Figure 2 3 and 3 , the fixing mechanism includes a fixed pipe 7. The fixed pipe 7 is fixedly connected in the perforation. Three clamping plates 11 distributed in a triangular shape are provided inside the fixed pipe 7, and the clamping plates 11 are in contact with the rotating shaft. Connecting plates 10 are movably connected between the three clamping plates 11 and the fixed pipe 7. On the side of the fixed pipe 7 opposite to the support plate 2, there is a movable pipe 8. One end of the movable pipe 8 is inserted into the fixed pipe 7. A circular ring 9 is threadedly connected to the outside of the movable pipe 8, and the circular ring 9 is movably connected to the fixed pipe 7. A motor 5 is fixedly connected to the support plate 2. A gear 6 is fixedly connected to the output shaft of the motor 5. A number of tooth grooves meshing with the gear 6 are provided on the outside of the circular ring 9.

[0028] The motor 5 is driven to rotate the gear 6, and the circular ring 9 is driven to rotate through the tooth blocks, so that the movable pipe 8 moves into the fixed pipe 7, thereby pushing the clamping plates 11 towards the rotating shaft, so as to clamp the rotating shaft, thereby realizing the clamping and fixing of the barbed roller 1.

[0029] As shown Figure 4 in Figure Figure 4 , grooves are provided on the opposite sides of the clamping plates 11 and the fixed pipe 7. Both ends of the connecting plate 10 are movably connected in the adjacent grooves, and a torsion spring is sleeved at the connection of the connecting rod and the groove.

[0030] When the clamping plate 11 approaches the rotating shaft, it drives the connecting plate 10 to deflect, thereby driving the torsion spring to compress, so as to facilitate the reset of the clamping plate 11 under the elastic force of the torsion spring after disassembly.

[0031] As shown Figure 2 in Figure Figure 2 , cover bodies 4 are fixedly connected to the opposite sides of the two support plates 2. The movable pipe 8, the circular ring 9 and the gear 6 are all located inside the cover body 4, and the motor 5 is fixedly connected to the inner wall of the cover body 4.

[0032] The cover body 4 provides protection for components such as the motor 5, the gear 6, and the movable pipe 8, avoiding damage to the components by external forces.

[0033] As shown Figure 5As shown in the figure, a plurality of annular grooves distributed axially are provided on the circumferential side surfaces of the rotating shafts at both ends of the barbed roller 1. Spherical grooves distributed axially are provided on each of the three clamping plates 11, and spheres 14 are clamped in the spherical grooves, and the spheres 14 are clamped with the annular grooves.

[0034] The barbed roller 1 is positioned by the engagement of the spheres 14 and the annular grooves, preventing the rotating shaft from axially moving in the fixed tube 7 and affecting the operation of the barbed roller 1, and the spheres 14 facilitate the rotation of the barbed roller 1 during operation.

[0035] Working principle: When in use, the two support plates 2 are symmetrically installed on the device through the first mounting plate 3 and the second mounting plate 12. The device is connected to an external power supply, and the electric slide table 13 is started to move the support plate 2 on this side away. The barbed roller 1 is placed between the two support plates 2, and then the electric slide table 13 is started to move the support plate 2 back to its original position, so that the rotating shafts at both ends of the barbed roller 1 are inserted into the adjacent fixed tubes 7. The motor 5 is started, the motor 5 drives the gear 6 to rotate, and drives the ring 9 to rotate, so that the movable tube 8 moves into the fixed tube 7. The movable tube 8 pushes the clamping plate 11 against the rotating shaft, making the clamping plate 11 closely adhere to the rotating shaft, thereby fixing the barbed roller 1 and completing the clamping and fixing of the barbed roller 1.
