Description

Technical Field

[0001] The invention relates to textile finishing equipment, in particular to an automatic cleaning mechanism for card clothing. Background Art

[0002] Card clothing is a covering for various combing parts with needles or teeth on the surface, and is one of the important parts of spinning. In the raising machine equipment, the card clothing plays the role of piercing the fabric and hooking and cutting the fibers, giving the fabric a certain velvety feel. However, after the card clothing has been used for a period of time, a large amount of hair and thread ends will be stuck in the middle of the card clothing, which will not only affect the service life of the card clothing, but also affect the raising style and efficiency. The main method for cleaning the card clothing is to use a hook knife manually. That is, when the needle roller rotates, the hook knife is manually inserted into the card clothing and the hair and thread ends are hooked out with the hook knife. However, this operation is not only time-consuming and labor-intensive, but also may cause finger injuries or even arm injuries caused by being caught in the needle roller if one is not careful, which poses a great safety hazard. Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] As shown in the accompanying drawings, an automatic cleaning mechanism for card clothing includes an installation assembly, a cleaning device, a motor assembly, a cylinder slider assembly and an electrical automation control cabinet. The cleaning device includes a cleaning roller assembly, a knife roller assembly and a supporting wheel assembly; the cleaning roller assembly includes a cleaning roller 2, the surface of the cleaning roller 2 is covered with a cleaning steel needle 1, the cleaning roller 2 is installed on a bearing seat 3 through a bearing, the bearing seat 3 is fixed on the mounting seats 4 on both sides, and the mounting seat 4 is fixed to the push plate 8 on the mounting plate 5.

[0028] The knife roller assembly includes a knife roller 22, the outer ring of the knife roller 22 is octagonal, and each side is provided with a blade seat 21, and a blade 20 is installed on the blade seat 21. Linear bearings 25 are installed at both ends of the knife roller 22, and the linear bearings 25 are fixed on the mounting seats 4 on both sides.

[0029] The same end of one side of the cleaning roller 2 and the cutter roller 22 is respectively provided with a cleaning roller sprocket 16 and a cutter roller sprocket 32, and the cleaning roller sprocket 16 and the cutter roller sprocket 32 ​​are connected to the sprocket 13 through a chain 19 for transmission, and a tensioning wheel 17 is provided between the cleaning roller sprocket 16 and the cutter roller sprocket 32. The motor 28 is fixed on the motor base 14, and the motor base 14 is fixed on the mounting plate 5. The sprocket 13 is installed on the shaft head of the motor 28. The sprocket 13 transmits power to the cleaning roller 2 and the cutter roller 22 through the chain 19. The tensioning wheel 17 is used to tension the chain 19, and the sprocket 13 is driven to rotate by the motor 28, thereby achieving the synchronous rotation of the cleaning roller 2 and the cutter roller 22.

[0030] A cylinder slider assembly is provided on the mounting plate 5, and the cylinder slider assembly includes a push plate 8, a cylinder 9, a support plate 10 and a slider guide rail 11. The push plate 8 is fixed on the mounting plate 5, and the cylinder 9 is fixed to the support plate 10 through a cylinder seat 18. The piston rod of the cylinder 9 is fixed to the push plate 8, and the push plate 8 and the support plate 10 are connected through the slider guide rail 11. The extension and retraction of the piston rod of the cylinder 9 drive the push plate 8 forward and backward, thereby driving the cleaning device forward and backward.

[0031] The supporting wheel assembly includes a bracket 6, a supporting wheel 7, an adjustment rod 15, a supporting wheel shaft 33, and a supporting wheel seat 34. The bracket 6 is fixed to both sides of the mounting plate 5. The supporting wheel 7 is mounted on the supporting wheel shaft 33 via a bearing. The supporting wheel shaft 33 is fixed to the supporting wheel seat 34. The supporting wheel seat 34 is mounted on the bracket 6 and can slide back and forth within the chute of the bracket 6. The adjustment rod 15 is threadedly connected to the bracket 6 and is loosely connected to the supporting wheel seat 34. Rotating the adjustment rod 15 causes the supporting wheel seat 34 to slide back and forth within the chute of the bracket 6, thereby driving the supporting wheel 7 forward and backward. The forward and backward movement of the supporting wheel 7 controls the depth to which the cleaning needle 1 is inserted into the needle cloth 31.

[0032] A roller 27 is mounted on the other end of the cutter roller 22, and an end cam 26 is fixed to the mounting seat 4 on this side, with a compression spring 24 mounted on the inner stop of the shaft head. The end cam 26 is fixed to the mounting seat 4. When the motor 28 drives the cutter roller 22 to rotate, the roller 27 fixed to the cutter roller 22 will move along the trajectory of the end cam 26, realizing the axial transverse movement of the cutter roller, ensuring that the blade 20 can contact all the cleaning needles 1. The blade 20 is made of alloy steel with a thickness of 0.4mm and has a certain degree of elasticity in the transverse direction. The steel needle 1 is a round steel wire with a diameter of 0.3mm, and the steel needle 1 is planted on a rubber base cloth, which is wrapped around the cutter roller 22, so the steel needle 1 also has a certain degree of elasticity. When the cutter roller 22 rotates and the blade 20 contacts the steel needle 1, both will undergo a certain degree of elastic deformation due to the force, without damaging the blade 20 and the steel needle 1.

[0033] The machine further comprises a dust collection device, comprising an air knife 23 and a dust collection hood 12. The air knife 23 is installed between the cleaning roller 2 and the knife roller 22 and is connected to compressed air to blow off the blade 20 and remove hair scraps from the steel needle 1. The dust collection hood 12 is fixed to the mounting plate 5 and connected to a dust collecting fan to suck away the cleaned hair scraps to keep the site clean and tidy.

[0034] like Figure 7 、 Figure 8As shown, in actual use, the support plate 10 is fixed to the transverse movement mechanism 29 of the raising machine. Before operation, the cylinder 9 and air knife 23 are connected to compressed air, the motor 28 is energized, and the dust hood 12 is connected to the dust collection fan. After preparation is completed, the piston rod of the cylinder 9 is extended, and the two side rollers 7 are pressed against the card clothing 31 for positioning. The adjustment levers 15 on both sides are rotated to adjust the position of the rollers 7 so that the cleaning needle 1 penetrates the card clothing 31 to an appropriate depth. That is, when the rollers 7 move backward, the cleaning device moves forward under the push of the cylinder 9, and the penetration depth of the needle 1 into the card clothing 31 increases. Conversely, when the rollers 7 move forward, the penetration depth of the needle 1 into the card clothing 31 decreases. After adjustment is completed, the transmission motor of the raising machine needle roller 30 is started, causing the card clothing 31 to rotate in the carding direction. At the same time, the motor 28 of the cleaning device is started, driving the cleaning roller 2 and the knife roller 22 to rotate. At this time, the cleaning needle 1 hooks out the hair scraps in the needle cloth 31 and wraps the thread ends around the cleaning roller 2. The blade 20 on the knife roller 22 cuts off the thread ends wrapped around the cleaning roller 2. In order to ensure that the blade 20 can contact the entire surface of the cleaning roller 2, the knife roller 22 is moving back and forth axially when rotating. The air knife 23 and the dust hood 12 are responsible for blowing away the cleaned hair scraps and thread ends and sucking them into the dust collection fan. The electrical program controls the cleaning device to move back and forth horizontally on the transverse mechanism 29 to clean the entire needle roller 30. According to the amount of hair scraps in the needle cloth 31, the cleaning time of each needle roller 30 can be set in the electrical program. After cleaning one needle roller, the piston rod of the cylinder 9 retracts, the cylinder rotates a certain angle, and the piston rod of the cylinder 9 extends again to start cleaning the next needle roller 30. This cycle completes the automatic cleaning of the needle cloth of one device.
