[0027] The utility model provides a kind of roll press waste winding device, compared with prior art, when roll press needs to the waste winding of pole piece 12, the driving end of winding shaft 13 is supported stably by main support assembly, winding drive assembly starts operation, since its driving end transmission connection with winding shaft 13, power is transmitted, and driving winding shaft 13 rotates.This time, auxiliary support assembly is installed in the support end of winding shaft 13, cooperates with main support assembly, ensures that winding shaft 13 always keeps stable state during rotating winding waste, and waste is continuously wound to winding shaft 13.When winding shaft 13 completes waste winding task, needs to unload, and unloading drive assembly starts to play role.Unloading drive assembly drives auxiliary support assembly to separate from the support end of winding shaft 13, this time, winding shaft 13 only has driving end and is supported by main support assembly.Because auxiliary support assembly has been removed, the support end side of winding shaft 13 is in open state, and operating personnel can conveniently take down winding shaft 13 from main support assembly, or adopt other matched unloading tools, directly push waste roll from this end out of winding shaft 13, and complete unloading operation.Using the waste winding device of a kind of roll press provided by the utility model, just makes auxiliary support assembly separate by starting unloading drive assembly, can easily unload, without large-scale disassembly to entire winding shaft 13, greatly saves manpower, shortens unloading time, simultaneously avoids the damage of winding shaft 13 due to rough unloading, effectively guarantees production efficiency and equipment service life.

[0028] Please refer to Fig. 2 Main support assembly includes main mounting plate 11, and the outer wall of main mounting plate 11 is provided with fixed seat 24, and the driving end of winding shaft 13 is sequentially penetrated through main mounting plate 11 and fixed seat 24 and is rotationally cooperated with main mounting plate 11 and fixed seat 24, and transmission component is arranged in fixed seat 24, and winding drive assembly is arranged on the outer wall of fixed seat 24, and transmission component is respectively transmissionally connected with winding drive assembly and the driving end of winding shaft 13.

[0029] Main mounting plate 11 and fixed seat 24 provide firm support for the driving end of winding shaft 13, and the rotationally cooperated winding shaft 13 ensures accurate position when rotating, avoids shaking or deviation, guarantees the flatness and uniformity of waste winding, and improves winding quality.Transmission component efficiently transmits power, and by selecting appropriate transmission component type and parameter, the best power matching of drive assembly and winding shaft 13 can be realized, to meet the waste winding demand under different working conditions, such as chain 15 transmission, to ensure the stable rotation of winding shaft 13 and guarantee winding consistency.Winding drive assembly is installed on the outer wall of fixed seat 24, which is convenient for installation and disassembly.During equipment maintenance, maintenance personnel can directly operate drive assembly without removing complex components, saving time and cost, and transmission component in fixed seat 24 is also convenient for inspection, replacement and maintenance, improving equipment maintainability.

[0030] In addition, the main mounting plate 11 and the fixed seat 24 are sequentially penetrated by a bearing seat 26, the inside of the bearing seat 26 is provided with a bearing body 25, the driving end of the winding shaft 13 penetrates the bearing seat 26 and is rotationally matched with the bearing body 25. The bearing seat 26 and the bearing body 25 provide stable and accurate support for the driving end of the winding shaft 13. In the process of winding the waste materials, the winding shaft 13 will bear a large radial force and an axial force. The bearing seat 26 is fixed on the main mounting plate 11 and the fixed seat 24, and can effectively disperse these forces to the main support structure, preventing the winding shaft 13 from deviating or shaking.

[0031] Specifically, the transmission component includes a driving sprocket 16, a driven sprocket 23 and a chain 15, the driving sprocket 16 is connected to the winding drive assembly, the driven sprocket 23 is sleeved on the driving end of the winding shaft 13, and the chain 15 is wound on the driving sprocket 16 and the driven sprocket 23. The combination of the driving sprocket 16, the driven sprocket 23 and the chain 15 has many advantages. First, the transmission ratio of the chain 15 transmission is accurate, which can ensure the stable speed ratio between the winding drive assembly and the winding shaft 13, so that the waste material winding process is more uniform, and problems such as uneven winding of waste materials caused by unstable winding speed are avoided. Second, the chain 15 transmission has high transmission efficiency, which can reduce energy loss and reduce the operating cost of the equipment to a certain extent. Third, the structure of this transmission mode is relatively simple, and the installation and maintenance are convenient. When the chain 15 is worn or damaged, it can be easily replaced, which can effectively improve the maintenance efficiency of the equipment and reduce the maintenance difficulty.

[0032] Specifically, the winding drive assembly includes a servo motor 20, a speed reducer 19, a shaft coupling 18 and a magnetic powder clutch 17 connected in sequence, the magnetic powder clutch 17 is fixed to the outer wall of the fixed seat 24, and the driving sprocket 16 is connected to one end of the magnetic powder clutch 17 penetrating the fixed seat 24. The combination of the servo motor 20, the speed reducer 19, the shaft coupling 18 and the magnetic powder clutch 17 in the winding drive assembly can flexibly adjust the speed and torque of the winding shaft 13. The magnetic powder clutch 17 is installed on the outer wall of the fixed seat 24, and the torque transmitted can be flexibly adjusted by controlling the current. In the initial stage of winding, the waste material roll is small, and the required torque is also small, so the magnetic powder clutch 17 can correspondingly reduce the transmitted torque; as the winding process advances, the diameter of the waste material roll becomes larger, and the magnetic powder clutch 17 can increase the torque according to the actual situation, so as to always maintain the stability of the winding tension, avoid the problems of loose and wrinkled waste material caused by excessive or insufficient tension, and improve the winding quality.

[0033] Specifically, the winding shaft 13 is an air expansion shaft, and a gas pipe joint 22 is arranged at the end of the winding shaft 13 penetrating out of the fixed seat 24. The winding shaft 13 is designed as an air expansion shaft, and the gas pipe joint 22 at the driving end is matched, so that the clamping and unloading process is more convenient and efficient. When it is necessary to install the winding material, gas is introduced into the air expansion shaft through the gas pipe joint 22, the air expansion shaft expands rapidly, tightly supports the inner hole of the winding material, realizes rapid and firm clamping, and ensures that the material does not slide or deviate during winding. When unloading, the air in the air expansion shaft is released, the shaft body is contracted, and the wound waste roll can be easily taken off from the shaft. Compared with the traditional fixed shaft mode, the clamping and unloading time and labor cost are greatly saved. The gas pipe joint 22 is arranged at the end of the winding shaft 13 penetrating out of the fixed seat 24, which is convenient for connecting with the external gas source and does not affect the normal operation of other parts of the winding shaft 13. At the same time, the inflation and deflation operation of the air expansion shaft can be accurately controlled by an automatic control system, which is convenient for adapting to the overall automatic production process of the roller press. According to different production needs, the expansion degree of the air expansion shaft can be flexibly adjusted to adapt to winding of waste materials of various specifications and materials, thereby enhancing the universality and adaptability of the equipment.

The auxiliary support assembly shares part of the load of the winding shaft 13, reduces the wear and fatigue of the winding shaft 13 due to uneven stress, and the like. When unloading, the unloading driving assembly is started, the support component slides backward to separate from the support end of the winding shaft 13, the support end of the winding shaft 13 is released, and the operator can conveniently take down the wound waste material, thereby simplifying the unloading process, reducing the unloading difficulty, and saving the labor and time cost.

The two parallel and spaced transverse guide rails 35 provide precise sliding guide for the support component. When the unloading driving assembly pushes the support component to slide, the transverse guide rail 35 can effectively limit the movement track of the support component, so that it can only move forward and backward along the length direction of the guide rail, avoiding unstable conditions such as shaking and deviation. The arrangement of the transverse guide rail 35 makes the installation and disassembly of the support component more convenient. When the equipment is assembled or maintained, the worker can easily install or remove the support component along the transverse guide rail 35, reducing the difficulty of installation and maintenance. At the same time, this clear layout also facilitates the maintenance and replacement of the unloading driving assembly. Since the unloading driving assembly is located between the two guide rails, its position is relatively concentrated, which is convenient for workers to check, debug and maintain, reduces the equipment downtime and improves the maintainability of the equipment. The unloading driving assembly is a driving cylinder 34 fixed horizontally in the rear side of the inner wall of the auxiliary mounting plate 14, the driving end of the driving cylinder 34 is located at the front side thereof, and the driving end of the driving cylinder 34 is connected to the rear end of the support arm 33. The driving cylinder 34 drives the support arm 33 to act.

[0036] Specifically, the support component includes a support arm 33, a clamping groove 37 and a locking piece, the support arm 33 is slidably arranged on the two transverse guide rails 35, the clamping groove 37 is located at the front end of the support arm 33, and the locking piece is arranged at the bottom of the clamping groove 37.

The support arm 33 cooperates with the transverse guide rail 35 to slide accurately along the guide rail, ensuring the position accuracy of the support end of the winding shaft 13 during winding and unloading. The clamping groove 37 is located at the front end of the support arm 33, and its size and shape can be designed according to the support end of the winding shaft 13, which can tightly fit the winding shaft 13 to provide a stable support point for the winding shaft 13, share the weight and stress of the winding shaft 13 during work, reduce the deformation and shaking of the winding shaft 13, and ensure the uniformity and stability of the waste material winding. Before winding starts, the winding shaft 13 can be fixed firmly in the clamping groove 37 by locking through the locking piece, preventing displacement or falling of the winding shaft 13 during winding, and ensuring safe and reliable winding. When unloading, the locking piece is unlocked, and the winding shaft 13 can be easily taken out of the clamping groove 37, which is simple and convenient to operate, saving unloading time and labor cost.

[0037] Specifically, the locking member includes a locking cylinder 32 and a locking block 31, the locking cylinder 32 is vertically arranged at the bottom of the front end of the supporting arm 33, and the locking block 31 is arranged at the bottom of the clamping groove 37, the locking cylinder 32 is used for driving the locking block 31 to ascend or descend to lock or unlock the supporting end of the winding shaft 13.
