Description

A fully automatic octagonal soft-rolling drum with ventilation device Technical Field

[0001] This utility model relates to the technical field of leather processing equipment, and in particular to a fully automatic octagonal soft drum with a ventilation device. Background Technology

[0002] The octagonal drum body is octagonal in shape, with the outer wall of the drum consisting of eight equally divided rectangular plates and the side walls consisting of eight equally divided isosceles trapezoidal plates. This shape allows the leather to undergo more thorough and even tumbling and friction during the softening process. Compared with the traditional cylindrical drum, it can improve the softening effect and increase the loading capacity.

[0003] In the leather processing industry, tumbling drums are key equipment for improving the softness and feel of leather. Traditional tumbling drums are mostly cylindrical in structure, using rotation to tumble and rub the leather inside the drum. However, this method suffers from low ventilation efficiency and uneven temperature and humidity control, easily leading to localized hardening or mold growth, affecting the quality of the finished product. Furthermore, traditional equipment relies on manual monitoring and parameter adjustment, resulting in low production efficiency and difficulty in ensuring process stability. With the increasing demands for environmental protection, energy conservation, and intelligent technology in the leather industry, existing technologies are no longer sufficient to meet the requirements of efficient and precise production. The octagonal structure, due to its polyhedral characteristics, offers a greater advantage in ventilation design, optimizing airflow distribution and reducing dead zones within the drum. Simultaneously, combined with a fully automatic control system, it allows for real-time dynamic adjustment of parameters such as rotation speed, temperature, humidity, and ventilation volume, ensuring even force and sufficient ventilation during the tumbling process, thereby improving finished product quality and production efficiency.

[0004] A search revealed that Chinese Patent Publication No. CN205443339U discloses "a fully automatic octagonal tumbling drum with a ventilation device, comprising a frame, an octagonal drum body, a control panel, and a ventilation device. The octagonal drum body and the ventilation device are both mounted on the frame. The ventilation device is connected to the inner cavity of the octagonal drum body, and the control panel is mounted on the upper end of one side of the octagonal drum body. This fully automatic octagonal tumbling drum with a ventilation device improves the ventilation within the drum body, thereby enhancing the tumbling quality."

[0005] Existing fully automatic octagonal tumbling drums typically have a ventilation device at the top, which contains an exhaust fan to enhance ventilation. However, since the exhaust fan is installed inside the ventilation duct, it is usually equipped with a filter screen and other accessories nearby. The filter screen needs to be removed before the internal exhaust fan can be inspected, which greatly increases the difficulty of maintenance. In view of this, we propose a fully automatic octagonal tumbling drum with a ventilation device.

[0006] In view of this, we propose a fully automatic octagonal soft rotating drum with a ventilation device. Summary of the Invention

[0007] To overcome the technical defects of the existing technology, this utility model provides a fully automatic octagonal soft rotating drum with a ventilation device.

[0013] Preferably, the adjustment assembly includes a movable platform, which is slidably mounted on the top surface of the ventilation duct. Two fixed seats are fixedly mounted on the top surface of the side frame. A side groove and a U-shaped frame are fixedly mounted on the top surface of the ventilation duct. Two connecting seats are fixedly mounted on the U-shaped frame. Rollers are rotatably mounted in each of the two connecting seats. Steel wire ropes are fixedly mounted on each of the two fixed seats. The surfaces of the two steel wire ropes are in contact with the rollers, and the other ends of the two steel wire ropes are fixedly connected to the top surface of the movable platform. When the movable platform moves, the steel wire ropes will pull the side frame to rotate. When the side frame is unfolded, the exhaust fan in the ventilation duct can be inspected, which enhances the convenience of inspecting the exhaust fan and is more practical.

[0014] Preferably, the adjustment assembly further includes two mounting plates, which are fixedly mounted on the top surface of the ventilation duct. A lead screw is rotatably mounted between the two mounting plates, and the lead screw is threadedly connected to the moving table. When the lead screw rotates, it drives the moving table to move.

[0016] Preferably, two magnets are fixedly installed on one side of the ventilation pipe, and two iron plates are fixedly installed on the bottom surface of the side frame. The two iron plates are attracted to the two magnets respectively. When the ventilation pipe and the side frame are closed, the two iron plates and the two magnets respectively limit the side frame to one side of the ventilation pipe.

[0017] Preferably, a sealing strip is provided on one side of the ventilation duct, which enhances the sealing effect when the ventilation duct is closed with the side frame.

[0018] The beneficial effects of this utility model are:

[0019] 1. In this utility model, when the exhaust fan is turned on, the exhaust fan will discharge the air inside the octagonal rotating drum body to the outside. The air is filtered by the filter screen. When the filter screen is replaced, pull the pin outward. When the pin is disengaged from the second fixing sleeve, the limit on the filter screen is released. At this time, the filter screen can be removed from the side frame, thereby removing and replacing the filter screen.

[0020] This invention allows for easy maintenance of exhaust fans by starting a motor to rotate a lead screw. The rotation of the lead screw moves a movable platform, which in turn pulls a side frame via a steel cable. When the side frame unfolds, the exhaust fan inside the ventilation duct can be inspected, significantly improving the convenience of exhaust fan maintenance and making it quite practical.
