Description

Technical Field

[0001] This utility model relates to the field of filter cloth driving technology, and more specifically, to a rotary filter cloth servo drive mechanism. Background Technology

[0002] In the field of filter press technology, the method of driving the filter cloth rotation is a key component, directly affecting filtration efficiency and equipment stability. In existing technologies, the rotation of the filter cloth in filter presses typically uses a common motor drive scheme, such as an asynchronous motor or a DC motor, which drives the filter cloth movement through a mechanical transmission mechanism (such as a gearbox or pulley). However, this traditional driving method has significant drawbacks: (1) Low positioning accuracy: Ordinary motors lack precise position control capabilities, resulting in large deviations in the starting and ending positions of the filter cloth rotation (usually more than ±5mm), which will affect the tension and uniformity of the filter cloth, thereby reducing the filtration effect and product qualification rate; (2) Inflexible speed control: The speed adjustment of ordinary motors depends on mechanical speed regulation or frequency converters, which has a slow response speed and is prone to speed fluctuations under high load, causing the filter cloth to rotate unevenly, increasing equipment wear and energy consumption; (3) Insufficient protection mechanism: Existing solutions lack effective distance or torque protection functions. When the filter cloth is jammed or overloaded, the motor is prone to burnout or the transmission components are damaged, resulting in frequent equipment shutdowns and increased maintenance costs; (4) Poor stability: The transmission system is prone to vibration and noise during long-term operation, affecting the equipment life and operating environment.

[0003] In existing technologies, during the use of filter cloth drives, the filter cloth cannot stop running in time after it has completely flipped over. Current drive mechanisms have low precision and cannot respond quickly to stop operation. Therefore, we propose an improvement to this problem by creating a rotary filter cloth servo drive mechanism. Utility Model Content

[0004] The purpose of this invention is to address the problem that current filter cloth drive designs cannot stop operation promptly after the filter cloth body has completely flipped during the flipping process. Current drive mechanisms have low precision and cannot respond quickly to stop operation.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A servo drive mechanism for rotating filter cloth is proposed to improve the above-mentioned problems.

[0007] The application is as follows:

[0008] A servo drive mechanism for rotating filter cloth includes a drive bracket. A servo motor assembly is located at the center of one end of the drive bracket. The servo motor assembly includes at least two sets of servo motors. The outer end of each set of servo motors is meshed with a drive shaft. Both ends of the drive shaft are connected to a set of T-shaped steering boxes. The T-shaped steering boxes contain a pair of bevel gears arranged at right angles. A drive rod is movably connected to the other end of the T-shaped steering boxes. A T-shaped gear assembly is movably connected to the outer end of the drive rod. The T-shaped gear assembly includes a positioning bevel gear and a movable bevel gear that mesh vertically. A linkage shaft is fixed to the outer end of the movable bevel gear. A filter cloth body is located at the outer end of the linkage shaft. A filter cloth rotating component is movably connected to the outer end of the filter cloth body. A filter cloth support is fixed downwards to the outer end of the positioning bevel gear.

[0009] As a preferred technical solution of this application, in the T-type steering box, one bevel gear is fixed to one end of the drive shaft, and the other bevel gear is fixed to one end of the drive rod, with the outer end of the drive rod being fixedly connected to the positioning bevel gear.

[0010] As a preferred technical solution of this application, the positioning bevel gear and the movable bevel gear are meshed together, the movable bevel gear is fixed at one end of the linkage shaft, and the movable bevel gear and the positioning bevel gear are meshed together.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figures 1-5As shown, this embodiment proposes a rotary filter cloth servo drive mechanism, including a drive bracket. A servo motor group 1 is provided at the center of one end of the drive bracket. The servo motor group 1 includes at least two servo motors. The outer end of each servo motor is meshed with a transmission shaft 2. Both ends of the transmission shaft 2 are respectively connected to a set of T-shaped steering boxes 3. The T-shaped steering box 3 includes a pair of bevel gears arranged at right angles. The other end of the T-shaped steering box 3 is movably connected to a transmission rod 4. The outer end of the transmission rod 4 is movably connected to a T-shaped gear assembly 5. The T-shaped gear assembly 5 includes a vertically meshing positioning bevel gear 51 and a movable bevel gear 52. The outer end of the movable bevel gear 52 is fixed to a linkage shaft 8. The outer end of the linkage shaft 8 is provided with a filter cloth body 6. The outer end of the filter cloth body 6 is movably connected to a filter cloth rotating component 9. The outer end of the positioning bevel gear 51 is fixed downward to a filter cloth support 7.

[0028] In the T-shaped steering box 3, one bevel gear is fixed to one end of the drive shaft 2, and the other bevel gear is fixed to one end of the drive rod 4. The outer end of the drive rod 4 is fixedly connected to the positioning bevel gear 51.

[0029] The positioning bevel gear 51 and the movable bevel gear 52 are meshed together. The movable bevel gear 52 is fixed at one end of the linkage shaft 8, and the movable bevel gear 52 and the positioning bevel gear 51 are meshed together.

[0030] The filter cloth rotating component 9 includes a first sprocket 91 located at both ends of the linkage shaft 8, and a second sprocket 92 provided at the upper end of the filter cloth support 7. Both the first sprocket 91 and the second sprocket 92 are meshed and linked with a chain 97.

[0031] The first filter cloth positioning rod 93 and the second filter cloth positioning rod 94 are respectively provided at the head and tail ends of the chain 97. The first filter cloth positioning rod 93 and the second filter cloth positioning rod 94 are respectively fixed to one end of the filter cloth body 6.

[0032] The lower end of the filter cloth support 7 also has a first roller 95 and a second roller 96, which are used to fit against the inner side of the filter cloth body 6.

[0033] In the relevant fields of this case and application, the filter cloth body 6 has through holes sewn on all four sides for the tube to pass through, ensuring that the surface of the filter cloth body 6 can be fully unfolded in actual use and ensuring the flatness of the filter cloth body 6.

[0034] In actual use, the filter cloth body 6 that needs to be rotated and cleaned is first passed through the first filter cloth positioning rod 93 and the second filter cloth positioning rod 94 at both ends, and then the filter cloth body 6 is tensioned on the filter cloth support 7 by the first roller 95 and the second roller 96. In order to ensure that the filter cloth body 6 is fully tensioned, a fixing plate is provided at the first filter cloth positioning rod 93. The fixing plate has two sets of slots in opposite directions, and one of the long sides of the two sets of slots extends outward through the fixing plate. The first filter cloth fixing rod can adjust the fixed slot as needed. After the filter cloth body 6 is tensioned, the two ends of the first filter cloth positioning rod 93 (which is fixed to the chain 97 by the fixing plate, and the fixing plate is described here as part of the first filter cloth positioning rod 93), the second filter cloth positioning rod 94, and the chain 97 are fixed to each other by threaded connectors (threaded rod and threaded cylinder). Such fixing can ensure that the two ends of the filter cloth body 6 are properly limited on the first filter cloth positioning rod 93 and the second filter cloth positioning rod 94.

[0035] The fixing plate on the first filter cloth fixing rod can have a through hole at the upper slot so that the threaded rod connected by the chain 97 can pass through the through hole and form a threaded connection with the threaded cylinder.

[0036] The second filter cloth fixing rod can be provided with through holes at both ends so that the threaded rod connected by the chain 97 can be connected to the corresponding through holes and threadedly connected to them through the threaded cylinder.

[0037] After connecting the filter cloth to the chain 97, start the servo motor assembly 1. The servo motor assembly 1 uses existing technology, such as the YR series damping motor (this type of motor has a friction disc damping brake device built into the YS series standard motor, which helps the motor stop faster and more smoothly, and has a certain power when stopping, with fast stopping speed, and can achieve rapid forward and reverse rotation). The servo motor assembly 1 includes at least two servo motors. The two servo motors are fixed together by screws and other fixing parts. The shaft end of each servo motor is connected by a positioning bevel gear 51 and a movable bevel gear 52, which are like T-shaped gear combination 5. The positioning bevel gear 51 is fixed to the shaft end of the servo motor, and the movable bevel gear 52 is fixed to the corresponding transmission shaft 2 end. When the servo motor assembly 1 moves, it drives the shaft of the corresponding servo motor to rotate. The rotation of the servo motor shaft drives the connected bevel gear to mesh and rotate. This drives the corresponding drive shaft 2 to rotate. The rotation of the drive shaft 2 drives the bevel gear set in the T-shaped steering box 3 to rotate, which in turn drives the positioning bevel gear 51 on the drive rod 4 to rotate, which in turn drives the T-shaped gear assembly 5 to rotate. The rotation of the T-shaped gear assembly 5 drives the corresponding connected linkage shaft 8 to rotate. The rotation of the linkage shaft 8 drives the first sprocket 91 to rotate. The rotation of the first sprocket 91 drives the chain 97 in the filter cloth rotating part 9 to move. The movement of the chain 97 drives the second sprocket 92 to move (the second sprocket 92 is movably connected to the filter cloth support 7, mainly to ensure the connection of the chain 97 is stable and will not fall off). As a result, the filter cloth body 6, which is fixed at both ends of the chain 97, can roll and flip along the first roller 95 and the second roller 96, and stops when one end of the chain 97 can no longer rotate. At this time, the filter cloth body 6 has completed the flipping. When it is necessary to flip in the opposite direction, it is only necessary to control the servo motor assembly 1 to rotate in the opposite direction.

[0038] During this process, when the chain 97 and the first sprocket 91 and the second sprocket 92 cannot rotate, the servo motor is stopped by the infrared controller, and the braking is completed. The filter cloth body 6 is flipped. When it needs to be flipped again, the servo motor can be reversed by the controller. At the same time, when the chain 97 and the first sprocket 91 and the second sprocket 92 cannot rotate, the servo motor is stopped by the infrared controller, and the braking is completed.

[0039] In this application, the drive shaft 2 and drive rod 4 are both embedded in the servo bracket, and their rotation is not limited by friction. In addition, at least one set of filter cloth brackets 7 are fixed on the servo bracket to ensure stability. Each set of linkage shafts 8 is fixed with two sets of movable bevel gears 52 at the left and right ends, and the two ends of each set of linkage shafts 8 are movably positioned on the transverse brackets at both ends of the drive bracket.

[0040] The controllers and other components in this application all employ existing technologies. The circuit layout can be adjusted according to the actual needs of those skilled in the art, and all circuit layouts are existing technologies.

[0041] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0042] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
