Description

Technical Field

[0001] The present invention relates to the technical field of textile machinery, and particularly to a carding machine bottom sieve universal adjusting device. Background Art

[0002] A carding machine is one of the key devices in a dry non-woven fabric production line. It plays a crucial role in the production process of non-woven fabrics, connecting the front and the back, and has a vital impact on the production and product quality of the entire production line. It directly affects the quality of fiber web formation and ultimately affects the performance of the finished product. Today, with people's increasing requirements, the market has a large demand for high-quality non-woven fabrics, which also means higher requirements for carding web formation.

[0003] The accuracy of the distance between the card clothing and the bottom sieve is one of the key factors affecting the web formation quality of the carding machine. Although a high-precision carding machine bottom sieve is important, a convenient and reliable bottom sieve position adjustment device and the position accuracy of secondary assembly from the equipment manufacturing plant to the user site cannot be ignored either. Taking a double-cylinder and double-doffer carding machine as an example, according to the fiber carding process, the carding machine can be divided into four parts. However, for each part, there is the installation, adjustment, and fixation of the bottom sieve. The accuracy of the distance between the card clothing and the bottom sieve directly affects the web output quality of the carding machine. If the bottom sieve is not adjusted to the accurate distance, various problems will occur in the product, such as uneven fiber web, diagonal bars, horizontal bars, or longitudinal stripes on the cotton web; cloud spots, cotton knots, cotton web breakage on the fiber web surface, or even no cotton web output. These problems will greatly reduce the fabric output quality. Improper bottom sieve distance will also cause cotton accumulation, damage the card clothing, and cause corresponding mechanical failures. Therefore, the fixation, adjustment, and secondary installation of the carding machine bottom sieve directly affect the web formation efficiency and quality of the carding machine.

[0004] At present, there are two common connection methods for the bottom of the carding machine: one is that the bottom of the carding machine is installed in cooperation with the corresponding roller body, and both ends of the bottom of the carding machine are directly fixed on the wallboard by bolts. This connection method has certain drawbacks. Its adjustment amount is too small to meet the requirements of different gauges for more fiber varieties; the adjustment difficulty is relatively large, and it is difficult to ensure the consistency of the gauge between the bottom of the carding machine and the roller body, which affects the carding and net output quality. The other is that both ends of the bottom of the carding machine are connected through adjustment components such as connecting plates and positioning plates, and then the bottom of the carding machine is adjusted through components such as positioning blocks and adjusting bolts. Compared with the first connection method of the bottom of the carding machine, the adjustment range of the bottom of the carding machine is increased. Although the bottom of the carding machine can achieve the function of multi-directional adjustment, this connection method of the bottom of the carding machine has the following drawbacks: 1. The connecting plate and the positioning plate are relatively large in size, so a relatively large installation and adjustment space is required, which is not conducive to the on-site installation of the small space in the feeding part; 2. When the positioning plates at both ends of the bottom of the carding machine are adjusted through the adjustment bolts, if the adjustment is improper, the bottom of the carding machine is easily distorted and deformed, destroying the processing accuracy of the bottom of the carding machine; 3. Part of the bottom of the carding machine cannot be shipped as a whole machine. When shipped from the equipment factory, it needs to be removed from the carding machine and reassembled on-site at the customer's site. Therefore, this structure cannot ensure the accuracy of on-site secondary assembly, and it is necessary to make fine adjustments again. In addition, the small parts removed may be lost during transportation. Summary of the Invention

[0005] The purpose of the present invention is to provide a universal adjustment device for the bottom of a carding machine. This adjustment device miniaturizes and modularizes the bottom adjustment device, which is convenient for installation and adjustment. When on-site secondary installation is required, it can quickly and accurately align, effectively ensuring the accuracy of the gauge between the bottom of the carding machine and the corresponding roller, and greatly improving the net output quality and production efficiency of the carding machine during high-speed production.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a universal adjustment device for the bottom of a carding machine, the structure of which includes a pin shaft, a sliding sleeve, a sliding block and a fixed block. One side of the sliding block is provided with a convex key, and one side of the fixed block is provided with a concave key groove. The sliding block and the fixed block achieve relative sliding through the cooperation of the convex key and the concave key groove. The sliding sleeve is sleeved on the pin shaft, and the sliding block and the fixed block are sleeved on the sliding sleeve. The corresponding two sides of the sliding block and the fixed block are respectively provided with components for adjusting the left and right movement of the bottom of the carding machine, and the corresponding upper and lower surfaces of the fixed block are respectively provided with components for adjusting the up and down movement of the bottom of the carding machine.

[0007] Furthermore, one end of the pin shaft is provided with a handle, and the other end of the pin shaft is provided with a stepped shaft that cooperates with the pin hole of the bottom of the carding machine.

The top of the sliding sleeve is provided with a limiting groove for preventing the axial movement of the sliding sleeve, and one side of the sliding sleeve is provided with a set screw I.

[0009] Further, a guide pin is provided at the top of the sliding block. The lower end of the guide pin passes through the top wall of the sliding block and abuts against the limiting groove at the top of the sliding sleeve. A setscrew two is provided at the bottom of the sliding block; on the left and right corresponding sides of the sliding block, components for adjusting the up-and-down movement of the bottomless sieve are provided respectively. The components for adjusting the up-and-down movement of the bottomless sieve are adjusting screws. The end of the adjusting screw passes through the side wall of the sliding block and abuts against the side wall of the sliding sleeve. A long hole is provided at each of the four corners of the sliding block, and a fixing screw is provided in the long hole.

[0010] Further, components for adjusting the up-and-down movement of the bottomless sieve are provided on the upper and lower corresponding surfaces of the fixing block. The components for adjusting the up-and-down movement of the bottomless sieve are hex socket head cap screw three and hexagon head bolt. The lower end of the hex socket head cap screw three passes through the top wall of the fixing block and abuts against the top wall of the sliding sleeve. The free end of the screw rod of the hexagon head bolt passes through the bottom wall of the fixing block and abuts against the bottom wall of the sliding sleeve. An inner hexagon screw two for fixing is provided at one end of the lower part of the fixing block.

[0011] Further, components for adjusting the left-and-right movement of the bottomless sieve are also provided on the left and right corresponding surfaces of the fixing block. The components for adjusting the left-and-right movement of the bottomless sieve are adjusting screws. The end of the adjusting screw passes through the side wall of the fixing block and abuts against the side wall of the sliding sleeve.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The adjusting device of the present invention drives the pin shaft to move through the up-and-down and left-and-right movement of the sliding sleeve, so as to realize the adjustment of the bottomless sieve in any direction, meeting the requirement of pitch adjustment when replacing products. At the same time, the installation of this device does not require complex processing of the wall and supporting parts. By connecting the pin shaft with the end face of the bottomless sieve, the bottomless sieve will not be distorted and deformed due to improper manual operation during the installation and adjustment process.

[0014] 2. Due to the compact structure and tight installation of the fixing block, sliding block, sliding sleeve and pin shaft, this adjusting device is very small and can meet the installation and adjustment requirements of the narrow space in the feeding part of the carding machine.

Detailed implementation mode

[0021] The universal adjusting device for the bottomless sieve of the carding machine of the present invention will be described in detail with reference to the accompanying drawings of the specification.

[0022] Two sets of this device are used on both sides of each bottomless sieve. By adjusting the adjusting screw, the bottomless sieve can be adjusted in any direction within the plane, thereby changing the distance between the bottomless sieve and the corresponding roller body. When the distance is adjusted to the ideal position, the fastening screw can be locked. Because the pin shaft of this device is a stepped surface when inserted into the pin hole of the bottomless sieve, the bottomless sieve can be controlled not to move axially along the pin shaft, and only the distance can be adjusted within the plane. As Figure 4 shown, in this example, this device is first installed on the fixed bracket, as Figure 3 shown, when the outer bracket is not required at the use position, this device can be directly installed on the circular wall panel.

[0023] As Figure 1 , Figure 2 shown, the universal adjusting device for the bottomless sieve of the carding machine of the present invention includes a pin shaft 2, a sliding sleeve 3, a sliding block 8 and a fixed block 11. One side of the sliding block 8 is provided with a convex key, and one side of the fixed block 11 is provided with a concave key groove. The sliding block 8 and the fixed block 11 achieve relative sliding through the cooperation of the convex key and the concave key groove. The sliding sleeve 3 is sleeved on the pin shaft 2, and the sliding block 8 and the fixed block 11 are sleeved on the sliding sleeve 3. Corresponding sides of the sliding block and the fixed block are respectively provided with components for adjusting the left and right movement of the bottomless sieve, and corresponding upper and lower surfaces of the fixed block are respectively provided with components for adjusting the up and down movement of the bottomless sieve.

[0024] A guide pin 12 is provided at the top of the sliding block 8. The lower end of the guide pin 12 passes through the top wall of the sliding block 8 and abuts against the limit groove 15 at the top of the sliding sleeve 3. A set screw two 14 is provided at the bottom of the sliding block 8; components for adjusting the up and down movement of the bottomless sieve are respectively provided on the left and right corresponding sides of the sliding block 8. The components for adjusting the up and down movement of the bottomless sieve are adjusting screws 6. The end of the adjusting screw 6 passes through the side wall of the sliding block 8 and abuts against the side wall of the sliding sleeve 3. Long strip holes are respectively provided at the four corners of the sliding block 8, and fixing screws are provided in the long strip holes. The fixing screws are Allen screws one 5. The sliding block 8 is installed with the fixed block 11 through the Allen screws one 5 and washers 7. Loosening the four Allen screws one 5 can realize the up and down sliding of the sliding block 8 along the concave key groove on the fixed block 11.

[0025] The upper and lower corresponding surfaces of the fixed block 11 are provided with components for adjusting the up and down movement of the bottomless sieve. The components for adjusting the up and down movement of the bottomless sieve are the hexagon socket head screw III 13 and the hexagon head bolt 10. The lower end of the hexagon socket head screw III 13 passes through the top wall of the fixed block 11 and abuts against the top wall of the sliding sleeve 3. The free end of the screw rod of the hexagon head bolt 10 passes through the bottom wall of the fixed block and abuts against the bottom wall of the sliding sleeve 3. One end of the lower part of the fixed block 11 is provided with a hexagon socket head screw II 9, and the fixed block can be installed on the circular wall panel 16 or the fixed bracket 17 through the hexagon socket head screw II 9. When the bottomless sieve 18 needs to be adjusted up and down, first loosen the hexagon head bolt 10 at the bottom of the fixed block, and then rotate the hexagon socket head screw I 5 on the sliding block to ensure that the sliding block 8 has space for up and down movement. Then rotate the hexagon socket head screw III 13 at the top of the fixed block 11. When the hexagon socket head screw III 13 moves downward, since the hexagon socket head screw abuts against the top of the sliding sleeve 3, the sliding sleeve 3 is subjected to a downward pressure and moves downward. When the sliding sleeve 3 moves downward, since the sliding block 8 is sleeved with the sliding sleeve 3, the sliding block 8 moves downward together with the sliding sleeve along the concave key groove on the fixed block. When the sliding sleeve 3 moves downward, it drives the pin shaft 2 to move, and finally the pin shaft 2 drives the bottomless sieve 18 to move downward. If the bottomless sieve 18 needs to be adjusted upward, first loosen the hexagon socket head screw III at the top of the fixed block, and then rotate the hexagon socket head screw I 5 on the sliding block to ensure that the sliding block has space for up and down movement. Then rotate the hexagon head bolt 10 at the bottom of the fixed block. The upward movement of the hexagon head bolt drives the sliding sleeve, and the sliding sleeve then drives the sliding block to move upward along the concave key groove on the fixed block. At the same time, the pin shaft 2 also moves upward, and finally the pin shaft 2 drives the bottomless sieve 18 to be adjusted upward.

[0026] One end of the pin shaft 2 is provided with a handle 1, and the pin shaft 2 can be inserted into or pulled out of the pin hole of the bottomless sieve 18 through the handle 1. The other end of the pin shaft is provided with a stepped shaft that fits with the pin hole of the bottomless sieve to ensure the stability of the connection between the pin shaft and the bottomless sieve.

[0027] The pin shaft 2 is inserted into the sliding sleeve 3, and the stepped shaft at the end of the pin shaft 2 extends outside the sliding sleeve 3 and is inserted and connected with the pin hole of the bottomless sieve through the stepped shaft. The top of the sliding sleeve 3 is provided with a limiting groove for preventing the axial movement of the sliding sleeve. One side of the sliding sleeve 3 is provided with a set screw I 4. After the pin shaft 2 is inserted into the sliding sleeve 3, when the position of the pin shaft is determined, the pin shaft can be locked through the set screw I 4 on the side of the sliding sleeve.

[0028] To improve the stability of the device during use, components for adjusting the left - right movement of the bottomless sieve are also provided on the corresponding left and right faces of the fixed block 11. The components for adjusting the left - right movement of the bottomless sieve are adjusting screws 6. The end of the adjusting screw 6 passes through the side wall of the fixed block and abuts against the side wall of the sliding sleeve 3. When it is necessary to adjust the left - right movement of the bottomless sieve, loosen the two adjusting screws 6 on the same side of the fixed block 11 and the sliding block 8 to ensure there is space for the sliding sleeve to move. Then, rotate the two adjusting screws on the other same side of the fixed block and the sliding block. Under the pushing force of the adjusting screws, the sliding sleeve 3 moves left or right. The movement of the sliding sleeve drives the pin shaft 2 to move left or right. Since the front end of the pin shaft is connected to the pin hole of the bottomless sieve through a stepped shaft, the left - or right - hand movement of the pin shaft drives the left - or right - hand movement of the bottomless sieve.

[0029] First, fix the fixed block 11 to the installation fixing bracket through the hexagon socket head cap screw II 9. The installation hole in the fixed block 11 is a counterbore hole, so the installation of the hexagon socket head cap screw II 9 does not affect the installation of the sliding block 8. After the sliding block and the fixed block are fitted through the convex key and concave key groove, then fasten the sliding block 8 to the fixed block 11 through the hexagon socket head cap screw I 5 and the washer 7. Screw the handle 1 into the pin shaft 2, then insert the pin shaft 2 into the sliding sleeve 3. Then insert the sliding sleeve 3 into the sliding block 8. The guide pin 12 at the top of the sliding block 8 just inserts into the limit groove at the top of the sliding sleeve 3. Apply a force through the handle 1 to insert the pin shaft 2 into the end face pin hole of the corresponding bottomless sieve 18, and then lock the pin shaft 2 through the set screw I 4 on the side of the sliding sleeve 3. When the bottomless sieve 18 needs to be adjusted up and down, loosen the hexagon socket head cap screw I 5, and push the sliding sleeve 3 to drive the sliding block 8 to move up and down along the key groove direction of the fixed block 11 by adjusting the hexagon socket head cap screw III 13 and the hexagon head bolt 10. At the same time, drive the pin shaft 2 to move up and down, thereby driving the bottomless sieve to move up and down. After the up - and - down position of the bottomless sieve is determined, lock the hexagon socket head cap screw I 5. When the bottomless sieve 18 needs to be adjusted left and right, only need to adjust the adjusting screws 6 on the left and right sides of the fixed block 11 and the sliding block 8. The adjusting screw 6 pushes the sliding sleeve 3 to move left and right along the key groove direction at its top. At the same time, drive the pin shaft 2 to move left and right, thereby driving the bottomless sieve to move left and right. After the left - and - right position of the bottomless sieve is determined, lock the adjusting screw 6. When the bottomless sieve needs to be removed for shipment, loosen the set screw I 4 on the side of the sliding sleeve 3, and pull out the pin shaft 2 from the pin hole of the bottomless sieve through the handle 1. The pin shaft 2 does not need to be completely pulled out of the sliding sleeve 3. When performing secondary installation on - site, only need to align and insert the pin hole of the bottomless sieve with the pin shaft 2. Since the position of the sliding sleeve 3 has not changed, there is no need to perform secondary adjustment on the bottomless sieve. For the bottomless sieve that needs to be removed for shipment, by loosening the pin shaft locking screw on the side of the sliding sleeve and pulling out the end - plate pin shaft of the bottomless sieve, there is no need to remove any other parts, so there is no risk of losing parts during transportation.

[0030] The adjusting device of the present invention can achieve the adjustment of the bottomless in any direction, and the adjustment range of the bottomless is at least 5 mm, which far meets the demand for pitch adjustment when replacing products. Since the adjusting device is very small, it can meet the installation and adjustment requirements in the narrow space of the feeding part of the carding machine. At the same time, the installation of this device does not require complex processing of the wall and supporting parts. It is connected to the end face of the bottomless through a pin shaft, and the bottomless will not be distorted and deformed due to improper manual operation during the installation and adjustment process.

[0031] As described above, only some principles of the present invention are illustrated by diagrams. This specification is not intended to limit the present invention to the specific structures and application scopes shown and described. Therefore, all possible corresponding modifications and equivalents that can be utilized belong to the scope of the patent applied for by the present invention.
