Description
Technical Field
[0001] The present invention relates to the technical field of drum processing, and specifically relates to a water-based leather drum processing device and a processing method thereof. Background Art
[0002] A drum refers to a rotating component in equipment such as a centrifuge, gas flowmeter, granulator, and flour mill, also known as a barrel. It is a rotating cylinder in the leather-making process where raw hides are flipped inside (such as for washing hides, pickling, tanning, and dyeing) or where fur is cleaned inside (by flipping together with fine sawdust). It is an important equipment widely used in leather factories, a wooden barrel with protruding studs or leather-lifting plates inside. Leather can be processed in batches inside the drum. When driven by gears to rotate, the hides inside the drum are subjected to continuous mechanical actions such as bending, stretching, pounding, and stirring, accelerating the chemical reaction process and changing the physical properties of the leather. The application range of the drum covers most wet processing procedures in leather-making and dry-state softening, raising, etc.
[0003] Due to the large volume of the drum, it is necessary to produce it in sections first during production, and then weld multiple small sections together to form the drum. In the prior art, a hoisting device is usually used to hoist two parts of the drum onto a platform and then welded manually. Since manual welding can only be carried out over a certain distance and cannot achieve continuous circumferential welding, and since the two drums need to be concentric during the welding process, the above method requires multiple adjustments to ensure concentricity, which greatly delays the processing efficiency of the drum. To solve the above problems, a water-based leather drum processing device and a processing method thereof are proposed herein. Summary of the Invention

[0014] A processing method of a water-based leather drum processing device, used to implement the above-mentioned water-based leather drum processing device, includes: S1: Place one half of the water-based leather drum barrel to be processed between two groups of clamping blocks. Start the first motor. The first motor drives the bidirectional lead screw to rotate. Due to the transmission of the synchronous pulley and the synchronous belt, the two bidirectional lead screws rotate synchronously. The clamping blocks on the outer surface of the bidirectional lead screw move towards the drum according to the size of the drum under the guidance of the limiting rod, and the drum is clamped and fixed by the arc-shaped positioning groove in the middle of the clamping block. Then place the other half of the water-based leather drum barrel on the placement ring; S2: Start the sixth motor. The sixth motor drives the third threaded rod to rotate, causing the support frame to move to the left along the sliding guide rail, moving the centering assembly into the other half of the aqueous leather drum cylinder. Start the seventh motor. The output shaft of the seventh motor drives the fourth threaded rod to rotate. The moving ring threadedly connected to the fourth threaded rod slides on the mounting rod. The movement of the moving ring drives the third connecting rod. At the same time, the first connecting rod and the second connecting rod on the first fixed ring and the second fixed ring also move accordingly. Finally, the inner support strip moves towards the inner wall of the drum and tightens, achieving centering and clamping of the drum. Subsequently, the sixth motor drives the third threaded rod to rotate, causing the support frame to continue moving to the left along the sliding guide rail until the two aqueous leather drum cylinders come into contact; S3: The position sensor detects the position to be welded. Start the third motor and the fourth motor. The third motor drives the first threaded rod to rotate, causing the first moving block to drive the second housing to move left and right. The fourth motor drives the second threaded rod to rotate, causing the second moving block to drive the laser welding head to move up and down, precisely adjusting the position of the laser welding head; S4: After the position adjustment is completed, sleeved the welding wire outside the sleeve screw rod and pass its end through between the driving roller and the driven roller. Start the laser welding head and the fifth motor. The fifth motor drives the driving roller to rotate. The driving roller and the driven roller cooperate to push the welding wire to the welding position. The second motor drives the transmission rod and the gear to rotate. The gear meshes with the toothed ring, causing the moving plate to move in a circular motion along the annular guide rail, thereby performing circular welding work.
[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. In the present invention, the bidirectional screw rod and the limiting rod in the fixing assembly cooperate with the clamping block to accurately adjust the clamping position according to the size of the drum. The arc-shaped positioning groove can stably fix the drum, ensuring the stability of the drum position during the processing, improving the processing accuracy. The centering assembly drives the fourth threaded rod through the motor, driving the moving ring and the connecting rod structure to achieve the centering support of the inner support strip for the drum, further ensuring the position accuracy of the drum during processing. Without multiple debugging, only by starting the device can the two drums be coaxially butted. Ensuring concentricity can evenly distribute heat, reduce welding stress, thereby reducing the risk of deformation, ensuring that the drum maintains the correct geometric shape, and ensuring concentricity of the drum can make the weld more uniform, ensuring the strength and tightness of the joint.
[0016] 2. In the present invention, the moving plate of the welding assembly can slide along the annular guide rail, and the circular motion is achieved through the meshing of the gear and the toothed ring. With the cooperation of the first and second threaded rods to adjust the position of the laser welding head, the welding operation can be flexibly carried out at different positions of the drum. The laser welding head is equipped with a driving roller and a driven roller, which can realize automatic welding, improve the welding efficiency and quality. Through continuous circular welding, one-time forming can avoid the accumulation of heat-affected zones caused by multiple weldings, reduce the concentration of thermal stress, thereby reducing the occurrence of welding defects, ensuring the quality and strength of the welded joint. The one-time forming circular welding can avoid repeated welding operations, reduce the operation time, and improve the production efficiency. Compared with the traditional segmented welding, continuous welding can reduce the welding process during the production process, thereby saving labor costs, material costs and time costs.
[0017] 3. The design of each component of this device enables it to adapt to the processing of water-based leather drums of different specifications. The bidirectional lead screw adjusts the position of the clamping block, and the inner support strip of the centering assembly can adjust the support position according to the change of the inner diameter of the drum. The multi-degree-of-freedom adjustment of the welding assembly can also meet the welding requirements of different drums, enhancing the versatility of the device. BRIEF DESCRIPTION OF THE DRAWINGS

Start the first motor (207). The first motor (207) drives the bidirectional lead screw (203) to rotate. Due to the transmission of the synchronous pulley (204) and the synchronous belt, the two bidirectional lead screws (203) rotate synchronously. The clamping blocks (205) on the outer surface of the bidirectional lead screw (203) move towards the drum direction according to the size of the drum under the guidance of the limiting rod (202).
