Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a roller with a long service life. Background Art

[0002] Rollers are cylindrical rotating parts in textile machinery that play the role of feeding, drafting, and output. They have the meaning of rollers and shafts and are widely used in drafting, combing, conveying and other mechanisms. According to the role they play, they are divided into drafting rollers, feeding rollers, pressing rollers, working rollers, etc.

[0003] The existing roller will gradually wear out during wire drawing, and the wear will reduce the service life of the roller, which will increase the production cost.

[0012] As a further description of the above technical solution:

[0013] The wear-resistant coating is a zirconium phosphate coating.

[0014] As a further description of the above technical solution:

[0015] The left and right sides of the inner cavity of the ceramic tube sleeve are provided with insertion holes.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The roller with a long service life is provided with a ceramic tube sleeve to improve the strength of the roller, and then provided with an aluminum alloy reinforcement layer and a chrome plating layer to further improve the strength and hardness of the roller. Finally, a wear-resistant coating is applied on the outermost side to improve the wear resistance of the roller, thereby reducing the wear of the roller during operation, thereby avoiding wear of the roller and increasing the service life.

[0018] 2. The roller with a long service life moves the pin by pushing the push rod, and then the spring contracts to move the end of the pin out of the socket, thereby unlocking the ceramic sleeve. The old ceramic sleeve is then slid off the main body and replaced with a new one, thereby eliminating the need to replace the entire roller and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The utility model provides a roller with a long service life, which can avoid the wear of the roller and increase the service life. When replacing, there is no need to replace the entire roller, which reduces the cost. Figure 1-4 , comprising a main body 100 and a ceramic sleeve 200;

[0028] Please refer again Figure 1-4 , the main body 100 is used to install the ceramic sleeve 200;

[0029] See also Figure 1-3 The ceramic sleeve 200 is clamped on the outer wall of the main body 100. The outer wall of the ceramic sleeve 200 is fixedly connected with an aluminum alloy reinforcement layer 210. The aluminum alloy reinforcement layer 210 is used to strengthen the hardness of the roller. The outer wall of the aluminum alloy reinforcement layer 210 is fixedly connected with a chrome plating layer 220. The chrome plating layer 220 is used to further strengthen the hardness of the roller. The outer wall of the chrome plating layer 220 is coated with a wear-resistant coating 230. The chrome plating layer 220 is used to improve the wear resistance of the roller. The ceramic sleeve 200 is provided to improve the overall strength of the roller. The aluminum alloy reinforcement layer 210 and the chrome plating layer 220 are provided to further improve the overall strength and hardness of the roller. Finally, the wear-resistant coating 230 is applied to the outermost side to improve the wear resistance of the roller, thereby reducing the wear of the roller when working.

[0030] In summary, the roller can be prevented from wearing and tearing and its service life can be prolonged.

[0031] See also Figure 2-4 The left and right side walls of the main body 100 are provided with mounting grooves 110 , the bottom and top of the inner cavity of the mounting grooves 110 are fixedly connected with springs 120 , and the end of the spring 120 is fixedly connected with a latch 130 , and the latch 130 can be plugged into the socket 240 through the spring 120 .

[0032] See also Figure 2 and Figure 4 The left and right side walls of the latch 130 are fixedly connected with a push rod 140 , and the latch 130 can be driven to move by the push rod 140 .

[0033] Please refer again Figure 2 and Figure 4 The left and right side walls of the inner cavity of the installation groove 110 are provided with a slide groove 150, and the inner cavity of the slide groove 150 is slidably connected with a slider 160, and the slider 160 is fixedly connected to the left and right side walls of the latch 130. The slider 160 moves with the latch 130, so that the latch 130 moves stably.

[0034] Please refer again Figure 1-3 The wear-resistant coating 230 is a zirconium phosphate coating, which has extremely strong wear resistance, thereby improving the wear resistance of the roller.

[0035] Please refer again Figure 1 , Figure 2 and Figure 4 The ceramic sleeve 200 has holes 240 on both sides of its inner cavity, through which the plug 130 can be plugged.

[0036] In summary, there is no need to replace the entire roller, thus reducing costs.

[0037] During specific use, personnel in this technical field first install the roller on a textile machine, and then when the roller is working, the overall strength of the roller is initially improved by the ceramic sleeve 200, and then the overall strength and hardness of the roller are further improved by the aluminum alloy reinforcement layer 210 and the chrome plating layer 220, and then the wear resistance of the roller is improved by the outermost wear-resistant coating 230. When the roller needs to be replaced, the push rod 140 is pushed to drive the pin 130 to move, and then the spring 120 is contracted to move the end of the pin 130 out of the socket 240, and finally the old ceramic sleeve 200 is slid out of the main body 100, and the new ceramic sleeve 200 is replaced on the main body 100.
