Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A water-based leather roller printing and finishing machine includes an assembly disc 101, an assembly screw 102 movably mounted within the assembly disc 101, a bearing sleeve 103 fixedly mounted within the assembly disc 101, a first bearing 104 fixedly mounted within the bearing sleeve 103, a locking cylinder 105 fixedly mounted within the first bearing 104, a limiting shaft 106 fixedly mounted within the locking cylinder 105, a printing roller 504 lockingly mounted on the outer side of the limiting shaft 106, a drive mechanism 201 provided on one side of the limiting shaft 106, the drive mechanism 201 including a slot 202, the assembly disc 101 movably mounted within the slot 202, an assembly screw hole 203 formed within the slot 202, and an assembly screw 102 screwedly mounted within the assembly screw hole 203.

[0025] The above scheme enables the rapid assembly and disassembly of the printing roller through the screwing action of the assembly disc and the assembly screw. The fixed installation of the bearing sleeve and the first bearing ensures the stable rotation of the locking cylinder. The fixed connection between the locking cylinder and the limiting shaft enables the power transmission between the printing roller and the drive mechanism. The slots and assembly screw holes in the drive mechanism ensure the detachable fixing of the assembly disc and the extension plate.

[0026] In this embodiment, preferably, the drive mechanism 201 further includes a support platform 204, a support frame 205 is fixedly installed at the bottom of the support platform 204, a support plate 206 is fixedly installed at the top of the support platform 204, a rotating motor 301 is fixedly installed on one side of the support plate 206, and a rotating track 302 is movably installed on the side of the support plate 206 away from the rotating motor 301.

[0027] The above solution improves the overall stability of the equipment by fixing the support platform and support frame, provides a power source for the rotating track by fixing the support plate and the rotating motor, and enables continuous conveying of the water-based leather after coating by cooperating with the rotating track and the extrusion roller.

[0028] In this embodiment, preferably, a squeezing roller 303 is movably installed on the side of the support plate 206 near the rotating track 302, a rotating shaft 304 is fixedly installed inside the squeezing roller 303, the rotating shaft 304 is movably installed inside the support plate 206, and an extension plate 305 is fixedly installed on the top of the support plate 206 near the rotating shaft 304.

[0029] The above scheme ensures uniform extrusion of water-based leather during coating by connecting the extrusion roller with the rotating shaft, and provides a supporting foundation for the limiting cylinder and the adjusting plate by fixing the extension plate.

[0030] In this embodiment, preferably, a slot 202 is provided on one side of the extension plate 305, and a second bearing 306 is fixedly installed on the side of the extension plate 305 away from the slot 202. A limiting cylinder 401 is fixedly installed inside the second bearing 306, and a limiting shaft 106 is movably installed inside the limiting cylinder 401.

[0031] The above scheme allows for the constraint of the rotation path of the limiting shaft through the slot on the extension plate and the fixed installation of the second bearing. The limiting sleeve and the limiting shaft can achieve synchronous driving of the printing roller by the drive motor.

[0032] In this embodiment, preferably, the limiting cylinder 401 is fixedly installed through the support plate 206 and the transmission box 402 at the driving end of the drive motor 403, the transmission box 402 is fixedly installed on one side of the extension plate 305, and the drive motor 403 is fixedly installed on one side of the transmission box 402.

[0033] The above solution allows for direct transmission of driving force by passing the limiting cylinder through the transmission box and connecting it to the drive motor. The fixed installation of the transmission box protects the meshing structure of the internal transmission sprocket and chain. The independent control of the drive motor enables precise adjustment of the printing roller speed.

[0034] In this embodiment, preferably, an adjustment plate 404 is fixedly installed on the top of the support plate 206 near the side of the extension plate 305. An adjustment groove 405 is provided in the adjustment plate 404, and a limit block 406 is movably installed in the adjustment groove 405.

[0035] The above scheme allows for the adaptation of water-based leather of different thicknesses through the sliding cooperation of the adjusting groove and the limiting block within the adjusting plate. The up-and-down movement of the limiting block enables dynamic adjustment of the pressure of the top roller on the rotating track.

[0036] In this embodiment, preferably, a spring 501 is fixedly installed at the top of the limiting block 406, an adjusting screw 502 is movably installed at the top of the spring 501, the adjusting screw 502 is screwed and installed at the top of the adjusting plate 404, and a top roller 503 is movably installed between the limiting blocks 406.

[0037] The above scheme can buffer the squeezing impact of the top roller on the water-based leather by linking the spring and the adjusting screw. The screwing control of the adjusting screw can realize the flexible adjustment of the spring preload. The rotational connection between the top roller and the limiting block can ensure that the water-based leather remains flat and wrinkle-free during the conveying process.

[0038] In this embodiment, a water-based leather roller printing and finishing machine is used such that when the device is powered on, the drive motor 403 drives the limiting cylinder 401 to rotate. The limiting cylinder 401 is located inside the transmission box 402 and is equipped with a transmission sprocket, on which a transmission chain meshes. When the drive motor 403 is working, the transmission chain meshes with the transmission sprocket and the chain, causing the limiting cylinder 401 to rotate synchronously under the support of the first bearing 104 and the second bearing 306. The limiting cylinder 401 and the engaging cylinder 105 are engaged with each other through the limiting structure on the end face, so that the limiting shaft 106 rotates with the limiting cylinder 401. The synchronous rotation drives the printing roller 504 to rotate stably. During rotation, the user inserts the water-based leather between the extrusion roller 303 and the printing roller 504. The rotation of the printing roller 504, through friction and extrusion, continuously conveys the water-based leather. During this conveying process, the printed pattern on the surface of the printing roller 504 is transferred to the surface of the water-based leather through extrusion contact, completing the printing process. After printing, the water-based leather immediately enters the area of ​​the rotating conveyor belt 302. The rotating conveyor belt 302 has multiple sets of roller structures inside and is driven by a rotating motor 301. The rotation of the rollers moves the surface of the conveyor belt, thus... The coated water-based leather is conveyed forward along the track. During the conveying process, the top roller 503 applies elastic pressure to the water-based leather on the track via the limiting block 406 connected to the spring 501. The squeezing action of the top roller 503 ensures the friction between the water-based leather and the rotating track 302, preventing material accumulation due to slippage. On the other hand, the extension allowance of the spring 501 can adaptively adjust the pressure to prevent excessive squeezing from damaging the coating structure of the water-based leather. When it is necessary to change the printing roller 504 with different printing patterns, the user can disassemble the assembly screw 102 and remove the assembly disc 101 from the slot 2. When the roller 504 is moved out of the mounting hole, the engagement between the limiting shaft 106 and the limiting cylinder 401 is released, and the limiting shaft 106 can be pulled out of the mounting hole of the printing roller 504. Since the printing roller 504 and the limiting shaft 106 are engaged by a keyway or spline, when replacing the roller 504, it is only necessary to align the engagement structure of the new printing roller 504 with the limiting shaft 106, re-insert it into the limiting cylinder 401, and lock the assembly plate 101 with the assembly screw 102 to complete the fixation. This design enables the quick replacement of the printing roller 504 without adjusting other parts of the drive mechanism 201, ensuring the efficiency of continuous production of the equipment.
