Description

A variable speed rotating device for a stainless steel octagonal soft-tumbler drum. Technical Field

[0001] This utility model relates to the technical field of octagonal soft-tumble drums, and in particular to a variable speed rotation device for a stainless steel octagonal soft-tumble drum. Background Technology

[0002] In the leather processing industry, the tumbling drum is the core equipment for softening leather. It uses centrifugal force to drive the leather to continuously collide and rub against rectangular baffles of the same height as the inner wall of the drum, thereby improving the softness, fullness, and elasticity of the leather. Currently, the mainstream tumbling drums on the market are mainly circular drums and octagonal drums: circular drums have a simple structure, but their leather loading capacity and tumbling efficiency are limited; octagonal tumbling drums, with their octagonal outer shell design, optimize the movement trajectory of the leather, significantly improving the loading capacity and tumbling intensity, meeting the needs of enterprises for production efficiency and product quality, and are therefore widely used.

[0003] However, existing octagonal soft-roll drums have significant shortcomings in equipment maintenance. Their variable-speed rotation device and the drum body are mostly fixedly connected by welding or dense bolts. In actual production, due to the complex environment of leather processing, problems such as leather entanglement and component wear frequently occur inside the drum. Whenever maintenance is needed, welded drums require disassembly with cutting tools, which can easily damage the equipment; bolted drums, due to their compact installation and numerous bolts, are time-consuming and labor-intensive to disassemble. This not only leads to long downtime, severely impacting production progress, but also increases labor costs and equipment wear risks, becoming a key challenge restricting efficient operation and maintenance in the leather processing industry.

[0004] Therefore, developing a stainless steel octagonal soft-tumbler rotating device that is easy to assemble and disassemble quickly and significantly improves maintenance efficiency is of great significance for reducing enterprise operation and maintenance costs and ensuring production continuity. Summary of the Invention

[0005] In order to solve the problems mentioned in the background art, the present invention provides a variable speed rotation device for a stainless steel octagonal soft-blow drum.

[0006] This utility model provides a variable speed rotation device for a stainless steel octagonal soft-tumbler drum, which adopts the following technical solution, including:

[0007] A base frame, on the top surface of which a top plate is fixedly installed, and on the top surface of the top plate two movable plates are slidably installed;

[0008] An octagonal soft-tumble drum body is provided, which is set between two movable plates. Each of the two movable plates is rotatably mounted with an installation shaft. Each of the two installation shafts is fixedly mounted with a sleeve block at one end that is close to each other. Both sides of the octagonal soft-tumble drum body are provided with sleeve grooves, and the two sleeve blocks are respectively movably connected to the two sleeve grooves.

[0009] An adjustment assembly, located on the top plate, is used to move two movable plates. When disassembling and repairing the octagonal soft-tumble drum body, motor A is started to rotate one of the bottom shafts. When one bottom shaft rotates, it drives the other bottom shaft to rotate through the cooperation of two sprockets and a chain. When the other bottom shaft rotates, it drives the two movable plates to move through the cooperation of two first connecting columns, two second connecting columns, and two connecting rods, causing the two movable plates to move away from each other. In principle, the sleeve block will disengage from the sleeve groove, allowing the octagonal soft-tumble drum body to be disassembled for easy repair.

[0010] Optionally, the adjustment assembly includes a turntable rotatably mounted on the top surface of the top plate. Side plates are fixedly mounted on the sides of the two movable plates that are close to each other. First connecting columns are fixedly mounted on the top surfaces of the two side plates. Second connecting columns are fixedly mounted on the top surfaces of the two turntables. Connecting rods are rotatably mounted inside the two second connecting columns. One end of each connecting rod is rotatably mounted on one of the first connecting columns. When disassembling and repairing the octagonal soft-tumble drum body, the rotation of the other bottom shaft, through the cooperation of the two first connecting columns, the two second connecting columns, and the two connecting rods, will drive the two movable plates to move away from each other. Under the principle of the two movable plates, the sleeve block will disengage from the sleeve groove. At this time, the octagonal soft-tumble drum body can be disassembled for convenient repair.

[0011] Optionally, the adjustment assembly further includes two bottom shafts, which are rotatably mounted on the top surface of the base frame. Sprockets are fixedly mounted on the outer side walls of both bottom shafts, and the same chain is provided on the two sprockets. The top end of one bottom shaft is fixedly connected to the bottom surface of the turntable. A motor A is fixedly mounted on the bottom surface of the top plate. The bottom end of the output shaft of motor A is fixedly connected to the top end of the other bottom shaft. When motor A is started, it drives one bottom shaft to rotate. When one bottom shaft rotates, it drives the other bottom shaft to rotate through the cooperation of the two sprockets and the chain.

[0012] Optionally, a first pulley is rotatably mounted on one side of one of the movable plates, and a second pulley is fixedly mounted on the other end of one of the mounting shafts. The first pulley and the second pulley are provided with the same belt. When the first pulley rotates, it drives the second pulley to rotate through the belt. When the second pulley rotates, it drives the octagonal soft-tumble drum body to rotate through the mounting shaft, thereby driving the octagonal soft-tumble drum body to rotate and realize the operation of the octagonal soft-tumble drum body.

[0013] Optionally, a connecting plate is fixedly installed on one side of one of the movable plates, and a motor B is fixedly installed on the top surface of the connecting plate. One end of the output shaft of the motor B is fixedly connected to one end of the first pulley, and starting the motor B drives the first pulley to rotate.

[0014] Optionally, multiple fixed base plates are fixedly installed on both sides of the base frame, and each of the multiple fixed base plates has mounting holes. By setting the fixed base plates and mounting holes, it is convenient to install and fix the base frame.

[0015] Optionally, the slot can be a hexagonal or octagonal structure. With the hexagonal or octagonal structure, when the slot is engaged with the block, the octagonal soft-tumble drum body can be stably installed and fixed.

[0016] In summary, this utility model has the following beneficial technical effects:

[0017] 1. In this utility model, when disassembling and repairing the octagonal soft tumbling drum body, the starting motor A drives one of the bottom shafts to rotate. When one bottom shaft rotates, it drives the other bottom shaft to rotate through the cooperation of two sprockets and a chain. When the other bottom shaft rotates, it drives two moving plates to move through the cooperation of two first connecting columns, two second connecting columns, and two connecting rods. This causes the two moving plates to move away from each other. In the principle of the two moving plates, the sleeve block will disengage from the sleeve groove. At this time, the octagonal soft tumbling drum body can be disassembled, which facilitates the repair of the octagonal soft tumbling drum body.

[0018] 2. In this utility model, when driving the octagonal soft-tumble drum body to rotate, the starting motor B drives the first pulley to rotate. When the first pulley rotates, it drives the second pulley to rotate through the belt. When the second pulley rotates, it drives the octagonal soft-tumble drum body to rotate through the mounting shaft, thereby driving the octagonal soft-tumble drum body to rotate and realizing the operation of the octagonal soft-tumble drum body.

One end of the two connecting rods 9 is rotatably mounted on the two first connecting columns 7 respectively. When the octagonal soft-tumble drum body 4 is disassembled and repaired, when the other bottom shaft 10 rotates, the two movable plates 3 will be moved by the cooperation of the two first connecting columns 7, the two second connecting columns 8 and the two connecting rods 9, so that the two movable plates 3 move away from each other. In principle, the sleeve block 20 will disengage from the sleeve groove 21. At this time, the octagonal soft-tumble drum body 4 can be disassembled, which is convenient for the maintenance of the octagonal soft-tumble drum body 4.

[0028] In this embodiment, the adjustment assembly also includes two bottom shafts 10, which are rotatably mounted on the top surface of the base frame 1.

When one of the bottom shafts 10 rotates, it drives the other bottom shaft 10 to rotate through the cooperation of two sprockets 11 and chain 12. When the other bottom shaft 10 rotates, it drives the two moving plates 3 to move through the cooperation of two first connecting columns 7, two second connecting columns 8 and two connecting rods 9, so that the two moving plates 3 move away from each other. When the two moving plates 3 move away from each other, the sleeve block 20 will disengage from the sleeve groove 21. At this time, the octagonal soft tumbling drum body 4 can be disassembled, which facilitates the repair of the octagonal soft tumbling drum body 4.

[0034] When the octagonal soft-tumble drum body 4 is driven to rotate, the starting motor B17 drives the first pulley 14 to rotate. When the first pulley 14 rotates, it drives the second pulley 15 to rotate through the belt 18. When the second pulley 15 rotates, it drives the octagonal soft-tumble drum body 4 to rotate through the mounting shaft 19, thereby driving the octagonal soft-tumble drum body 4 to rotate and realizing the operation of the octagonal soft-tumble drum body 4.
