Limiting mechanism for sueding machine

Abstract

The utility model discloses a limit mechanism for a sueding machine, which comprises a rack, two support grooves are arranged on the rack, the support grooves are arranged oppositely, springs I are arranged in the support grooves, support blocks are connected in the support grooves in a sliding manner, and the springs I abut against the support blocks. Through the cooperative arrangement of the supporting block and the mounting base, the upward thrust applied to the lower clamping shaft by the first abutting structure on the mounting base through the second spring is larger than the upward thrust applied to the two ends of the lower clamping shaft by the first spring through the supporting block, and therefore when the lower clamping shaft is subjected to downward pressure, most of the pressure is borne by the first abutting structure abutting against the shaft body of the lower clamping shaft; connecting parts at two ends of the lower clamping shaft are not easy to damage; through cooperative arrangement of the pressure plate and the pressure block, when the upper clamping shaft moves downwards, the L-shaped plate extrudes the pressure plate to push out the pressure block, the second abutting structure on the pressure block generates downward pressure on the shaft body of the upper clamping shaft, and therefore when the upper clamping shaft is subjected to upward pressure, the two ends of the upper clamping shaft are not prone to being damaged.

During the use of the suede sanding machine, the limit mechanism needs to limit the fabric so that the suede sanding roller can sand the fabric.

[0003] During use of the prior art sanding machine, the limiting mechanism usually clamps the fabric through two upper and lower clamping shafts. However, during the clamping process, a certain pressure needs to be applied to the fabric, so the two clamping shafts exert a certain pressure on each other, which can easily cause the clamping rod to break at the bearing connection supports at both ends.

[0011] Compared with the prior art, this technical solution has at least one of the following beneficial effects:

[0012] Through the coordinated arrangement of the support block and the mounting seat, the abutment structure 1 on the mounting seat exerts a greater upward thrust on the lower clamping shaft through the spring 2 than the spring 1 exerts on both ends of the lower clamping shaft through the support block, so that when the lower clamping shaft is subjected to downward pressure, most of the pressure is borne by the abutment structure 1 abutting against the shaft body of the lower clamping shaft, so that the connecting parts at both ends of the lower clamping shaft are not easily damaged;

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0019] See also Figures 1 to 3The embodiment of the present application provides a limiting mechanism for a sanding machine, including a frame 1, two supporting grooves 2 are provided on the frame 1, the supporting grooves 2 are through grooves, the supporting grooves 2 are arranged oppositely, a spring 3 is installed in the supporting groove 2, a supporting block 4 is slidably connected in the supporting groove 2, the spring 3 abuts against the supporting block 4, a lower clamping shaft 5 is rotatably connected to the supporting block 4, a plurality of mounting seats 6 are installed on the frame 1, the mounting seats 6 are provided with slide grooves 7, abutting structures 1 are slidably connected in the slide grooves 7, and the slide grooves 7 are provided with abutting structures 1. A spring 2 8 is installed, and the spring 2 8 abuts against the abutting structure 1; a mobile frame 9 is slidably connected to the frame 1, and a pressure groove 10 is provided on the mobile frame 9, and the pressure grooves 10 are arranged oppositely, and a pressure plate 11 is slidably and sealedly connected in the pressure groove 10, and a pressure block 12 is slidably and sealedly connected in the pressure groove 10, and an abutting structure 2 is installed on the pressure block 12, and an upper clamping shaft 13 is rotatably connected to the mobile frame 8, and two L-shaped plates 14 are installed on the frame 1, and the L-shaped plates 14 are arranged in coordination with the pressure plate 11.

[0020] In this embodiment, the movable frame 8 is moved downward so that the upper clamping shaft 13 rotatably connected thereto can clamp the cloth together with the lower clamping shaft 5 . The lower clamping shaft 5 is installed in the supporting groove 2 by the supporting block 4, and the spring 13 in the supporting groove 2 gives the supporting block 4 an upward thrust so that the supporting block 4 abuts against the top wall in the supporting groove 2, that is, an upward thrust is given to the two ends of the lower clamping shaft 5; at the same time, the abutting structure 1 sliding in the sliding groove 7 on the mounting seat 6 gives the lower clamping shaft 5 an upward thrust through the spring 2 8, and the upward thrust at the shaft body should be greater than the upward thrust at the two ends of the shaft, so that when the upper clamping shaft 13 moves downward and generates pressure on the lower clamping shaft 5, most of the pressure is borne by the abutting structure 1 that generates a large upward thrust on the shaft body of the lower clamping shaft 5, thereby reducing the probability of damage to the two ends of the lower clamping shaft 5; the pressure generated by the mutual squeezing of the upper clamping shaft 13 and the lower clamping shaft 5 is less than the elastic force given by the two springs, so that the lower clamping shaft 5 will not move; at the same time, the height of the lower clamping shaft 5 can be adjusted according to the elasticity of replacing the spring 1 3 and the spring 2 8, thereby improving practicality. When the upper clamping shaft 13 moves downward, the L-shaped block 14 installed on the frame 1 generates an upward thrust on the pressure plate 11, and the pressure plate 11 squeezes the pressure block 12 through the sealed pressure groove 10, so that the pressure block 12 moves downward, so that the abutment structure 2 can abut against the shaft body of the upper clamping shaft 13, and the greater the downward movement distance of the upper clamping shaft 13, the greater the pressure of the L-shaped plate 14 on the pressure plate 11, so that the downward thrust of the abutment structure 2 on the shaft body of the upper clamping shaft 13 is greater, thereby preventing the upper clamping shaft 13 from breaking at both ends.

[0021] In some embodiments, in order to facilitate the protection of the abutment structure 1 and the lower clamping shaft 5, the abutment structure 1 includes a slider 15, the spring 28 abuts against the slider 15, a U-shaped plate 16 is installed on the slider 15, and a plurality of rollers 17 are rotatably connected to the U-shaped plate 16.

[0024] In some embodiments, in order to facilitate precise control of the up and down movement distance of the upper clamping shaft 13 driven by the movable frame 8, a linear actuator 21 is installed on the frame 1. The linear actuator 21 can be an electric cylinder, and the output end of the linear actuator 21 is connected to the movable frame 8.

[0025] In some embodiments, in order to facilitate driving the upper clamping shaft 13 so that the cloth can be moved when the cloth is sanded, a rotating drive device 22 is installed on the moving frame 8. The rotating drive device 22 can be a motor. A gear 1 23 is installed at the output end of the rotating drive device 22. A gear 2 24 is installed at one end of the upper clamping shaft 13. The gear 1 23 is meshed and connected with the gear 2 24.
