Description

Technical Field

[0001] This application relates to the technical field of textile machinery, and in particular to a high-stability fleece pressure roller. Background Technology

[0002] A fabric pressure roller is a device used in the textile and materials processing industry to apply pressure to fabric. Its core function is to achieve the flattening, shaping, or pattern transfer of the fabric through mechanical pressure.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN204023213U, which discloses a variable fleece pressure roller, including a pressure cylinder. The pressure cylinder includes a cylinder body made of a flexible film and end caps at both ends. The pressure cylinder is filled with a liquid working medium. The end caps are composed of an inner end cap and an outer end cap arranged coaxially. The inner end cap is driven to rotate by a driver. A hollow roller with a surface full of through holes is coaxially fixed between the inner end caps at both ends. A radially arranged baffle is arranged around the outer periphery of the hollow roller. At least one grid plate parallel to the axis of the pressure cylinder is arranged in the space between the flexible film and the hollow roller.

[0004] However, in actual operation, the weight of the pressure roller is uneven due to the grid plates inside the roller. This makes the pressure roller very unstable when rotating, which easily generates large-amplitude vibrations. This leads to increased local wear on the pressure roller shaft and greatly shortens the service life of the pressure roller. Utility Model Content

[0005] To improve the stability of the pressure roller during rotation, this application provides a high-stability fleece pressure roller.

[0006] This application provides a high-stability fleece pressure roller, which adopts the following technical solution:

[0007] A high-stability fleece pressure roller includes a rotating shaft and a roller body disposed on the rotating shaft. The rotating shaft is equipped with an adjustment device for dynamically balancing the roller body. The adjustment device includes:

[0008] An adjusting ring is disposed on the rotating shaft;

[0009] The first adjusting block is provided with four first adjusting blocks. The first mounting mechanism is provided on the adjusting ring. The first adjusting block is detachably mounted on the adjusting ring through the first mounting mechanism. The four first adjusting blocks are evenly distributed around the adjusting ring with the rotating shaft as the center.

[0010] The second adjusting block is provided in a plurality of parts, and the mass of the second adjusting block is less than that of the first adjusting block. The adjusting ring is provided with a second mounting mechanism, and the second adjusting block is detachably mounted on the adjusting ring through the second mounting mechanism.

[0011] By adopting the above technical solution, an adjusting ring is installed on the rotating shaft, and then a first adjusting block and a second adjusting block are detachably installed on the adjusting ring through a first mounting mechanism and a second mounting mechanism. By adjusting the number and position of the first adjusting block and the second adjusting block on the adjusting ring, the dynamic balance of the entire pressure roller can be adjusted, ensuring the stability of the pressure roller when it rotates.

[0012] After performing a dynamic balance test on the pressure roller using a dynamic balancing tester, decide whether to install the first adjusting block based on the test results. If the first adjusting block is not required, directly install the second adjusting block for adjustment. If the dynamic balance requires a large adjustment, install the first adjusting block first, and then install the second adjusting block for fine adjustment. The adjustment work is convenient, quick, and efficient.

[0013] Optionally, a first trapezoidal groove is formed around the rotating shaft on the adjusting ring. The area of ​​the opening of the first trapezoidal groove is smaller than the area of ​​the bottom surface inside the first trapezoidal groove. The first adjusting block is slidably installed in the first trapezoidal groove. The first mounting mechanism includes:

[0014] The first mounting screw has a threaded hole on the first adjusting block, and the first mounting screw is threadedly connected to the threaded hole and abuts against the bottom wall of the first trapezoidal groove.

[0015] The first trapezoidal groove has an installation hole, and the first adjusting block enters the first trapezoidal groove through the installation hole. One end of the installation rotating block is rotatably mounted on the inner side wall of the installation hole.

[0016] A limiting component is disposed on the adjusting ring and is used to limit the position of the mounting block when it closes the mounting hole.

[0017] By adopting the above technical solution, a first trapezoidal groove is opened on the adjusting ring, the limiting component is unlocked, and the first adjusting block can be moved into the first trapezoidal groove after the mounting hole is opened by rotating the mounting block. After the first adjusting block enters the first trapezoidal groove and moves to the target position, the first mounting screw is turned to press against the bottom wall of the first trapezoidal groove, so that the first adjusting block is pressed against the first trapezoidal groove, thereby completing the installation of the first adjusting block in the first trapezoidal groove.

[0018] Optionally, the limiting component includes:

[0019] A limiting magnetic block is disposed on the bottom wall of a first trapezoidal groove having an installation hole;

[0020] A limiting magnetic strip is disposed on the mounting rotating block and is magnetically attracted to the limiting magnetic block.

[0021] By adopting the above technical solution, a limiting magnetic block is installed on the bottom wall of the first trapezoidal groove, and then a limiting magnetic strip is installed on the mounting block. The magnetic attraction between the limiting magnetic block and the limiting magnetic strip can complete the limiting work of the mounting block at the mounting hole.

[0022] Optionally, the limiting magnetic block is embedded in the bottom wall of the first trapezoidal groove, the surface of the limiting magnetic block is flush with the surface of the bottom wall of the first trapezoidal groove, the mass of the limiting magnetic block is the same as the mass missing from the embedding space opened on the bottom wall of the first trapezoidal groove for embedding the limiting magnetic block, the mounting block has an installation groove, the limiting magnetic strip is disposed in the installation groove, and the mass of the limiting magnetic strip is the same as the mass missing from the installation groove opened on the mounting block.

[0023] By adopting the above technical solution, the mass of the limiting magnetic block is set to be the same as the mass missing from the embedding space opened on the bottom wall of the first trapezoidal groove for embedding the limiting magnetic block, and the mass of the limiting magnetic strip is set to be the same as the mass missing from the mounting groove opened on the mounting block, thereby reducing the influence of the weight of the limiting magnetic block and the limiting magnetic strip on the dynamic balance of the adjusting ring.

[0024] Optionally, a second trapezoidal groove is formed around the rotating shaft on the adjusting ring. The second trapezoidal groove communicates with the mounting hole, and a plurality of second adjusting blocks slide into the second trapezoidal groove through the mounting blocks. The second mounting mechanism includes:

[0025] The mounting block has a sliding hole on its side wall, and the mounting block is slidably disposed in the sliding hole;

[0026] The second mounting screw has a threaded hole that communicates with the sliding hole on the second adjusting block. The second mounting screw is threadedly connected to the threaded hole. The mounting block has an inclined guide surface on the side wall near the second mounting screw. The guide surface contacts the second mounting screw. Under the action of the second mounting screw, the mounting block partially protrudes out of the sliding hole and abuts against the inner side wall of the second trapezoidal groove.

[0027] By adopting the above technical solution, after rotating the mounting block to open the mounting hole, the second adjusting block is moved into the second trapezoidal groove. Then, the second mounting screw is screwed to connect with the threaded hole on the second adjusting block. After the second mounting screw moves and contacts the guide surface on the mounting block, the guide surface will generate a component force that drives the mounting block away from the second mounting screw. Tightening the second mounting screw so that the mounting block is pressed against the inner side wall of the second trapezoidal groove completes the installation and fixing of the second adjusting block in the second trapezoidal groove.

[0028] Optionally, the adjusting ring is provided with a fixing component, and a dust cover is detachably provided on one side of the adjusting ring where the first trapezoidal groove and the second trapezoidal groove are provided through the fixing component.

[0029] By adopting the above technical solution, a dust cover is installed on the adjusting ring, thereby reducing the probability of dust and other impurities in the working environment of the pressure roller entering the first trapezoidal groove or the second trapezoidal groove of the adjusting ring, and ensuring the adjustment capability of the first adjusting block and the second adjusting block opening in the first trapezoidal groove and the second trapezoidal groove.

[0030] Optionally, the fixing assembly includes four fixing plates, and the adjusting ring has four insertion holes evenly distributed around the rotating shaft. The four fixing plates are all mounted on the dust cover and are inserted into the insertion holes.

[0031] By adopting the above technical solution, the movable dust cover moves the four fixed insert plates, allowing them to engage with the four insertion holes, thus completing the installation of the dust cover and the adjusting ring. When the dust cover needs to be removed, simply move it to disengage the four fixed insert plates from the four insertion holes. The structure is simple, and the operation is convenient and quick.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By installing an adjusting ring on the rotating shaft, and then detachably installing a first adjusting block and a second adjusting block on the adjusting ring through a first mounting mechanism and a second mounting mechanism, the dynamic balance of the entire pressure roller can be adjusted by adjusting the number and position of the first adjusting block and the second adjusting block on the adjusting ring, thus ensuring the stability of the pressure roller when it rotates.

[0034] 2. By installing a limiting magnetic block on the bottom wall of the first trapezoidal groove and then installing a limiting magnetic strip on the mounting block, the limiting position of the mounting block at the mounting hole can be achieved through the magnetic attraction between the limiting magnetic block and the limiting magnetic strip.

[0035] 3. By moving the dust cover, the four fixed insert plates are moved, allowing them to engage with the four insertion holes, thus completing the installation of the dust cover and the adjusting ring. To remove the dust cover, simply move it to disengage the four fixed insert plates from the four insertion holes. The structure is simple, and the operation is convenient and quick.
