Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment, specifically a biodegradable fabric processing device. Background Technology

[0002] During the fabric processing, the fabric needs to be impregnated by a padding machine. However, biodegradable fabrics use different materials, so the rubber rollers that match the fabric need to be replaced during the padding process.

[0003] However, with existing technology, when replacing rubber rollers, since the rubber rollers are mounted on the frame via bearings and one end is connected to the motor via a coupling, the bearings and couplings need to be disassembled during disassembly, and the bearings need to be slowly and precisely adjusted during installation to avoid misconnection to the overall equipment. Therefore, replacing rubber rollers is time-consuming and labor-intensive, affecting overall work efficiency. Summary of the Invention

[0004] To address the above problems, the present invention provides a biodegradable fabric processing device, comprising a material tank for holding a processing liquid, a frame mounted on both sides of the material tank, and a rubber roller positioned above the material tank to squeeze the fabric. A shaft with two ends extending outwards from the middle of the rubber roller is inserted through the middle of the roller, and the two ends of the shaft are mounted on the frame via bearings. The device is characterized by: The shaft core and the bearing are detachably connected via a quick-connect fitting. At least one locking hole is provided on the outer circumferential surface at both ends of the shaft core; The quick-connector includes a mounting shaft fixed to the bearing's movable ring. The end of the mounting shaft facing the shaft core has a radial positioning structure for circumferentially limiting the shaft core. A movable sleeve that can move along the axial direction is sleeved on the mounting shaft. At least one radially retractable locking block is provided in the end of the movable sleeve near the shaft core. The locking block is adapted to a locking hole to lock and release the shaft core. The quick connector also includes a locking mechanism provided on the movable sleeve to control the extension and retraction of the locking block; The locking and disengaging mechanism of the locking block enables the locking and disengaging of the mounting shaft and the shaft core, while the axially movable sleeve facilitates the rapid installation and disassembly of the rubber roller.

[0005] Furthermore, the radial positioning structure includes a V-shaped seat disposed on the end face of the mounting shaft, and the end of the shaft core is provided with a V-shaped notch that matches the V-shaped seat.

[0006] Furthermore, the outer circumferential surface of the mounting shaft is provided with a straight groove arranged along the axial direction. There are three straight grooves, which are evenly distributed radially along the center of the mounting shaft. A protrusion that slides with the straight groove is provided on the inner side of the movable sleeve near the bearing end.

[0007] Furthermore, the locking block is slidably embedded in the mounting groove opened in the movable sleeve, and the spring is housed in the mounting groove, providing a preload force to the locking block to make it tend to extend radially outward. The locking block is T-shaped, consisting of a square block set in the mounting groove and a cylinder that can slide out of the mounting groove, which cooperates with the T-shaped slot of the mounting groove to confine the locking block to slide in the mounting groove. The side of the square block away from the cylinder is in contact with the spring.

[0008] Furthermore, the locking block has a through hole along its axial direction, and a spiral guide groove is formed on the inner wall of the through hole.

[0009] Furthermore, the locking assembly includes a gear ring surrounding the outside of the movable sleeve with its teeth facing inward, and a transmission assembly disposed inside the gear ring and meshing with it. The transmission assembly transmits power to the locking block, thereby enabling the locking block to extend and retract. A rotatable and slidable protective sleeve is provided outside the movable sleeve. The protective sleeve is a hollow straight cylinder with openings at both ends, enclosing the gear ring and the transmission assembly inside. The gear ring is connected to the inner side of the protective sleeve. The openings at both ends of the protective sleeve are respectively provided with protruding rings, which slide in engagement with annular grooves provided on the outer surface of the movable sleeve.

[0010] Furthermore, the transmission assembly includes a gear that meshes with the gear ring inside the gear ring, and a rotating shaft that is connected to the gear through a bevel gear transmission pair. The rotating shaft passes through the movable sleeve, with one end located in the through hole of the locking block and the other end located outside the movable sleeve. A rollable ball is embedded on the outer side of the end located in the through hole. The ball slides in conjunction with the spiral guide groove, causing the rotating shaft to rotate and drive the locking block to extend and retract.

[0011] Furthermore, the bevel gear transmission pair consists of two vertically meshing bevel gears, one of which is connected to one end of the rotating shaft located outside the movable sleeve, and the other is connected to the gear via a shaft. The two ends of the shaft are respectively movably mounted on a support plate connected to the outside of the movable sleeve.

[0012] Furthermore, the protective sleeve is provided with a reset assembly at one end near the mounting shaft. The reset assembly includes a reset spring and a ring sleeve that limits and guides the reset spring. The ring sleeve is connected to the protective sleeve to form an annular movable cavity, allowing the reset spring to move within the cavity. A fixed plate and a movable plate are respectively connected to both ends of the reset spring. The fixed plate is fixedly connected to the outside of the movable sleeve to fix the circumferential angle. The movable plate is connected to the inner side wall of the ring sleeve and drives the movable sleeve to rotate and reset the circumferential angle under the elastic force of the reset spring. When relaxed, the return spring keeps the movable sleeve in the reset state. In the reset state, the locking block extends outward to lock. When the movable sleeve rotates along the direction of the fixed plate, the locking block retracts inward to relax, thus achieving quick installation and disassembly.

[0013] Furthermore, there are three locking blocks and three locking holes, which are evenly distributed circumferentially.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The quick-connect design allows for direct disassembly and installation of the rubber roller without removing the bearings and couplings. During installation and disassembly, only rotation and pulling actions are required, which is quick and convenient, shortens the time required, and improves overall work efficiency.

[0015] The V-shaped seat and V-shaped notch design allow for initial positioning of the rubber roller during installation and support during disassembly, avoiding repeated confirmation of the installation position and making installation easier. Attached Figure Description

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Examples, such as Figures 1-11 As shown: The present invention provides a biodegradable fabric processing device, the structure of which includes a material tank 1 for holding a processing liquid, a frame 2 set on both sides of the material tank 1, a rubber roller 3 set above the material tank 1 for squeezing the fabric, and a shaft core 4 with two ends extending out of the rubber roller 3 passing through the middle of the rubber roller 3. The two ends of the shaft core 4 are mounted on the frame 2 through bearings 5.

[0029] The key feature of this invention is that the shaft core 4 and the bearing 5 are detachably connected by a quick connector 6.

[0030] Specifically, the shaft core 4 has at least one locking hole 41 on its outer circumferential surface at each end. The quick-connect component 6 includes a mounting shaft 60 fixed to the movable ring of the bearing 5. The end of the mounting shaft 60 facing the shaft core 4 has a radial positioning structure for circumferentially limiting the shaft core 4. A movable sleeve 61 that can move along the axial direction is sleeved on the mounting shaft 60. At least one radially retractable locking block 610 is provided in the end of the movable sleeve 61 near the shaft core 4. The locking block 610 is adapted to the locking hole 41 to lock and release the shaft core 4. The quick-connect component 6 also includes a locking mechanism 62 provided on the movable sleeve 61 to control the extension and retraction of the locking block 610.

[0031] Through the above structural design, the locking and separation between the mounting shaft 60 and the shaft core 4 can be achieved by the extension and retraction of the locking block 610, and the rubber roller 3 can be quickly installed and disassembled in conjunction with the axially moving movable sleeve 61.

[0032] To facilitate the initial positioning of the rubber roller 3 during installation, the radial positioning structure is further designed. The radial positioning structure includes a V-shaped seat 600 located on the end face of the mounting shaft 60, and a V-shaped notch 40 at the end of the shaft core 4 that matches the V-shaped seat 600. When the two match, the rubber roller 3 can be initially positioned radially.

[0033] To ensure that the movable sleeve 61 only moves axially, the design includes a straight groove 601 on the outer circumferential surface of the mounting shaft 60, which is arranged along the axial direction. There are three straight grooves 601, which are evenly distributed radially along the center of the mounting shaft 60. A protrusion 611 is provided on the inner side of the movable sleeve 61 near the bearing 5, which slides in the straight groove 601. The protrusion 611 slides in the straight groove 601 to fix the movable sleeve 61 in the radial direction, ensuring that the shaft core 4, which is locked together with the movable sleeve 61, can rotate synchronously with the mounting shaft 60.

[0034] In order for the locking block 610 to extend and retract in the radial direction, the locking block 610 is specifically designed to be slidably embedded in the mounting groove 612 opened in the movable sleeve 61. The spring 614 is housed in the mounting groove 611 and provides a preload force to the locking block 610, which makes it tend to extend radially outward. The locking block 610 can be automatically pushed out without external force to achieve automatic locking.

[0035] The locking block 610 is formed by a square block set in the mounting groove 612 and a cylinder that can slide out of the mounting groove 612, forming a T shape. It cooperates with the T-shaped slot of the mounting groove 612 to confine the locking block 610 to slide within the mounting groove 612. The side of the square block away from the cylinder of the locking block 610 is in contact with the spring 614. The design of the square block fixes the radial angle of the locking block 610 itself, allowing it to only perform telescopic movement, which facilitates the telescopic control of the locking block 610 in the next step through the locking assembly 612.

[0036] In order to cooperate with the locking block 610 to achieve control, the locking block 610 has a through hole 610a along its axial direction, and a spiral guide groove 610b is formed on the inner wall of the through hole 610a.

[0037] Specifically, the locking assembly 612 includes a gear ring b surrounding the outer side of the movable sleeve 61 with its teeth facing inward, and a transmission assembly a located inside the gear ring b and meshing with it. The transmission assembly a transmits power to the locking block 610, enabling the extension and retraction of the locking block 610. A rotatable and slidable protective sleeve c is provided outside the movable sleeve 61. The protective sleeve c is a hollow straight cylinder with openings at both ends, enclosing the gear ring b and the transmission assembly a inside. The gear ring b is connected to the inner side of the protective sleeve c, thus ensuring that the rotation center of the gear ring b is consistent with the rotation center of the movable sleeve 61 through the protective sleeve c.

[0038] The protective cover c has protruding rings c1 at both ends, which slide in a ring groove 613 on the outer surface of the movable sleeve 61, thus fixing the protective cover c axially and allowing it to rotate circumferentially. The transmission assembly a includes a gear a1 that meshes with the gear ring b inside the gear ring b, and a rotating shaft a3 that is connected to the gear a1 via a bevel gear transmission pair a2. The rotating shaft a3 passes through the movable sleeve 61, with one end located in a through hole 610a in the locking block 610 and the other end outside the movable sleeve 61. A rolling ball a30 is embedded on the outer surface of the end located in the through hole 610a, and the ball a30 slides in a spiral guide groove 610b. Therefore, the design of the ball a30 sliding inside the ball a30 enables the rotating shaft a3 to rotate and drive the locking block 610 to extend and retract.

[0039] It should be specifically noted that the bevel gear transmission pair a2 consists of two vertically meshing bevel gears. One bevel gear is connected to one end of the rotating shaft a3 located outside the movable sleeve 61, and the other is connected to gear a1 through shaft a4. The two ends of shaft a4 are respectively movably mounted on the support plate a5 connected to the outside of the movable sleeve 61.

[0040] Finally, to facilitate the automatic reset of the locking assembly 612 without external force, a reset assembly d is provided at one end of the protective sleeve c near the mounting shaft 60. The reset assembly d includes a reset spring d1 and a ring sleeve d2 that limits and guides the reset spring d1. The ring sleeve d2 is connected to the protective sleeve c to form an annular movable cavity, allowing the reset spring d1 to move within the cavity. A fixed plate d3 and a movable plate d4 are connected to both ends of the reset spring d1, respectively. The fixed plate d3 is fixedly connected to the outside of the movable sleeve 61 to fix the circumferential angle. The movable plate d4 is connected to the inner wall of the ring sleeve d2 and, under the elastic force of the reset spring d1, drives the movable sleeve 61 to rotate and reset the circumferential angle. When relaxed, the return spring d1 keeps the movable sleeve 61 in the reset state. In the reset state, the locking block 610 extends outward to lock. When the movable sleeve 61 rotates along the direction of the fixed plate d3, the locking block 610 retracts inward to relax, thus realizing quick installation and disassembly.

[0041] To make the locking more secure, there are three locking blocks 610 and three locking holes 41, which are evenly distributed circumferentially.

[0042] When replacing the rubber roller, the operator first rotates the protective sleeve c. The protective sleeve c drives the gear ring b to rotate, which in turn drives the gear a1. Through the bevel gear pair a2, the transmission direction is changed, causing the rotating shaft a3 to rotate. The ball bearing a30 at the end of the rotating shaft a3 rolls within the spiral guide groove 610b, driving the locking block 610 to retract radially inward against the preload of the spring 614, completely disengaging it from the locking hole 41 of the shaft core 4. Then, the movable sleeve 61 is pulled axially towards the bearing 5, completely disengaging the locking block 610 from the end area of ​​the shaft core 4. Finally, the entire rubber roller assembly 3 can be removed directly.

[0043] When installing a new rubber roller, align the V-shaped notch 40 at the end of the new roller's shaft core 4 with the V-shaped seat 600 of the mounting shaft 60 and push it in to achieve initial positioning and circumferential limiting. Push the movable sleeve 61 along the mounting shaft 60 towards the shaft core 4. Once the movable sleeve 61 is in place, release the protective sleeve c. Under the action of the return spring d1, the locking mechanism 62 resets, and the locking block 610 automatically springs into the locking hole 41 of the shaft core 4 under the action of the spring 614, completing the final locking. The three-point layout ensures the stability of the connection and the balance of torque transmission.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
