[0033] The limit adjusting component 20 includes a limit pin 210, a compression spring 220, a fastening device 230, and an adjusting piece 240. The movable pressure disc 10 is provided with a polygonal hole 110. The limit pin 210 is arranged in the polygonal hole 110 and is movably arranged along the axial direction of the limit pin 210. The limit pin 210 includes an adjusting part 211, a limit part 212, and a stop part 213. The limit part 212 is consistent with the shape of the polygonal hole 110 and is clamped in the polygonal hole 110. The stop part 213 is located on the inner side of the movable pressure disc 10 and is used to abut against the tensioning wheel frame block 310. The adjusting part 211 is located on the outer side of the movable pressure disc 10. The fastening device 230 is connected to the outer side of the movable pressure disc 10. The fastening device 230 has a compression space for the adjusting part 211. The compression spring 220 is sleeved on the adjusting part 211 and is arranged between the limit part 212 and the top of the fastening device 230. The top end of the adjusting part 211 is arranged to protrude from the top of the fastening device 230. The top end of the adjusting part 211 is provided with a through hole extending along the radial direction of the adjusting part 211. The adjusting piece 240 is arranged to protrude from the through hole.

[0034] Specifically, the packing belt movable pressure disc 10 includes a movable pressure disc 10, a limit adjusting component 20, and an existing pressure disc component 30. The movable pressure disc 10 and the existing pressure disc component 30 are combined to form a device for installing a packing belt. The movable pressure disc 10 is detachably arranged on the existing pressure disc component 30 by screw thread connection to facilitate the replacement of the packing belt. The limit adjusting component 20 is used to assist in disassembling and assembling the movable pressure disc 10. The limit adjusting component 20 is arranged on the movable pressure disc 10. Thus, the movable pressure disc 10 can be conveniently disassembled without the aid of external tools.

[0035] The limiting adjustment assembly 20 comprises a limiting pin 210, a compression spring 220, a fastening device 230 and an adjustment piece 240. The limiting pin 210 can pass through the polygonal hole 110 on the movable pressing plate 10 to serve as a limiting stop after the movable pressing plate 10 assembly is installed in place, avoiding loosening of the movable pressing plate 10. Further, the polygonal hole 110 is in a stepped shape, and a section close to the outside of the movable pressing plate 10 is a square hole 111, and a section close to the inside of the movable pressing plate 10 is a circular hole 112. The limiting part 212 is a square block corresponding to the square hole 111. The stepped shape can form square holes 111 and circular holes 112 of different sizes. When the limiting part 212 is clamped in the square hole 111, the bottom can also abut on the circular hole 112 to prevent the limiting pin 210 from falling inward of the movable pressing plate 10. The limiting pin 210 specifically comprises an adjustment part 211, a limiting part 212 and a stop part 213. The stop part 213 is used to stop the tensioning wheel frame block 310 of the existing pressing plate assembly 30, so as to avoid rotation when the movable pressing plate 10 is loosened. The limiting part 212 is used to prevent the entire limiting pin 210 from rotating to keep fixed. Therefore, it is consistent with the shape of the square hole 111 on the movable pressing plate 10, and the size corresponds to ensure the effect of limiting rotation. The adjustment part 211 is used to control and adjust the entire limiting pin 210 to change the stop state of the limiting pin 210, so as to cancel the stop when disassembling the movable pressing plate 10, and then stop after the movable pressing plate 10 is installed. The compression spring 220 cooperates with the fastening device 230 to install and fasten the limiting pin 210. Through the elastic pre-tightening force of the compression spring, the limiting pin 210 remains in a compressed state and will not fall out of the movable pressing plate 10. The adjustment piece 240 can be easily controlled by technicians as a holding part of the technician. It is connected to the part of the adjustment part 211 extending from the fastening device 230, and also can serve as a limiting function to prevent the limiting pin 210 from falling inward of the movable pressing plate 10. In a preferred embodiment, the adjustment piece 240 can adopt a pull ring for convenient operation, or can be a horizontal pull rod by lifting the pull rod.

[0036] Thus, when the packing belt is to be replaced, the adjusting member 240 (pull ring) is pulled to drive the limiting pin 210 to move, so that the limiting portion 212 leaves the square hole 111, and then a certain angle is rotated and clamped, at this time the stop portion 213 is retracted to a position that will not stop the tensioner frame block 310, the movable pressure plate 10 can be rotated to disassemble; after the new packing belt is installed in place and tightened, the adjusting member 240 (pull ring) is pulled back to rotate a certain angle and drive the limiting pin 210 to move so that the limiting portion 212 is clamped in the square hole 111 and remains stationary under the action of the compression spring, and if it is loosened and rotated, the movable pressure plate 10 will not be loosened and rotated in the opposite direction due to the stop of the stop portion 213 (and the adjacent tensioner frame block 310), thereby improving the self-locking stability of the entire device, and the entire belt replacement process does not need to rely on external tools, and the operation is simple and convenient.

[0037] As a preferred embodiment of the present application, the stop portion 213 has a slope surface.

[0038] It should be noted that the slope surface can be used when the movable pressure plate 10 is loosened, and the movable pressure plate 10 can be tightened without pulling out the limiting pin 210, and the adjustment can be met under the guidance of the slope surface; however, it should be noted that when the slope surface is set, the end without the slope surface needs to be directed to the tensioner frame block 310 on the counterclockwise side for stopping (in the counterclockwise direction), and the slope surface is directed to the tensioner frame block 310 on the clockwise side, so that when the movable pressure plate 10 is tightened for loosening adjustment, it is first squeezed and contacted through the slope surface; the meaning is that the movable pressure plate 10 is taken as an example, in this example, the clockwise direction is to tighten the movable pressure plate 10, and the counterclockwise direction is to loosen the movable pressure plate 10, when the movable pressure plate 10 needs to be tightened due to loosening, the movable pressure plate 10 is rotated clockwise, and since the slope surface is also directed to the next adjacent tensioner frame block 310 on the clockwise side, it will be in contact with the slope surface, and under the action of the slope surface, the compression spring is squeezed and compressed to slide through this tensioner frame block 310 until it is tightened, preferably, the inclination angle of the slope surface can be set to 45°-50°; when the loosening condition is too large, the movable pressure plate 10 is loosened in the counterclockwise direction, the end of the stop portion 213 without the slope surface is directed to the previous adjacent tensioner frame block 310 in the counterclockwise direction, at this time, they will stop each other, thereby avoiding excessive loosening and rotation, and facilitating timely tightening, and the limiting pin 210 needs to be pulled out when the entire movable pressure plate 10 needs to be disassembled, please refer to the drawings for details.

[0039] As a more preferred embodiment of the present application, a plurality of wear plates 120 are further included, the movable pressure plate 10 has a plurality of spokes 130 arranged at intervals along the ring shape thereof, and the wear plates 120 are connected to the inner side of the spokes 130.

[0040] It should be noted that the wear plate 120 is used to reduce the wear between the spoke 130 of the movable platen 10 and the side of the tension wheel frame block 310, and is therefore connected to the inner side of the spoke 130; in a preferred embodiment, the wear plate 120 can be made of wear-resistant steel, such as high manganese steel, alloy wear-resistant steel, etc., and the thickness can be set to 10-12 mm, which can ensure wear resistance while avoiding too much thickness affecting tightening, and those skilled in the art can select according to actual conditions.

[0041] As a preferred embodiment of the utility model, the fastening device 230 includes a door-shaped block 231 and two flanges 232 protruding from the bottom end of the door-shaped block 231, the flanges 232 are connected to the outer side of the movable platen 10, the inner side of the door-shaped block 231 has the pressing space, the adjusting part 211 and the pressing spring 220 are arranged in the pressing space, and the top end of the adjusting part 211 protrudes from the top of the door-shaped block 231.

[0042] It should be noted that the door-shaped block 231 and the flange 232 are used to form a "horse riding" shape, so that the space (pressing space) inside the door-shaped block can be used to install and arrange the adjusting part 211 and the pressing spring 220, and the flange 232 can be used to connect to the movable platen 10, which is simple in structure and convenient to operate; when connected, the flange 232 can be connected by bolts, which is convenient for processing and facilitates disassembly for later maintenance and replacement.

[0043] The above is only a preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
