Description

Technical Field

[0001] The utility model relates to the technical field of all-polyester cloth sanding, in particular to an automatic regulating device for sanding pressure of all-polyester cloth. Background Art

[0002] Sueding is a process in the textile industry. The cloth is rubbed by a sanding machine and emery leather to form a layer of short velvet on the surface of the fabric. It not only retains the original characteristics but also gives the fabric a new style, increases warmth retention and softness, and has a rich texture. It has the characteristic of not fading and the color is long-lasting. It is often used in the production of all-polyester fabrics.

[0003] In the prior art, since pure polyester fabric is long, the amount of fluff at different positions is different, and the existing sanding machines usually do not have a mechanism to detect the thickness of the fabric, so the sanding mechanism is mostly fixed and the sanding effect is poor. Therefore, it is necessary to design an automatic adjustment device for the sanding pressure of pure polyester fabric. Utility Model Content

[0004] Based on this, it is necessary to provide an automatic adjustment device for the sanding pressure of all-polyester cloth to address the above technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an automatic adjustment device for the sanding pressure of all-polyester fabrics, comprising a frame, wherein a guide sanding roller 1 and a guide sanding roller 2 are respectively installed at both ends of the frame, the frame is rotatably connected to a plurality of fixed rollers, the plurality of fixed rollers are arranged flush, a plurality of linear actuators are installed on the frame, a force sensor is installed at the output end of the linear actuator, a mounting seat is installed on the force sensor, a detection wheel is rotatably connected to the mounting seat, the detection wheel corresponds to the fixed sanding roller one by one, the spacing between the detection wheel and the fixed roller is gradually reduced from the guide sanding roller 1 to the guide sanding roller 2, an adjusting sanding mechanism is installed on the frame, and the adjusting sanding mechanism is located on the side close to the guide sanding roller 2.

[0006] Preferably, the adjusting sanding mechanism comprises a sanding roller one and a sanding roller two, which are arranged in cooperation with each other, the sanding roller one is rotatably connected to a frame, a sliding frame is slidably clamped on the frame, the sanding roller two is rotatably connected to the sliding frame, a linear actuator two is mounted on the frame, the output end of the linear actuator two is connected to the sliding frame, a rotating drive device one is mounted on the frame, the output end of the rotating drive device one is transmission connected to the sanding roller one, a rotating drive device two is mounted on the sliding frame, the output end of the rotating drive device two is transmission connected to the sanding roller two.

[0011] Preferably, two telescopic support rods are installed on the frame, the two telescopic support rods are located on both sides of the second linear actuator, and the output ends of the telescopic support rods are connected to the sliding frame.

[0012] Compared with the prior art, this technical solution has at least one of the following beneficial effects:

[0013] By coordinating the fixed roller and the detection wheel, when the cloth that is always in contact with the bottom of the fixed roller exerts pressure on the detection wheel, the number of fluffs at different positions on the cloth can be determined by detecting the readings of the force sensor, thereby automatically adjusting the adjusting sanding mechanism.

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figures 1 to 3 The embodiment of the present application provides an automatic adjustment device for the sanding pressure of all-polyester fabrics, comprising a frame 1, with a guide sanding roller 2 and a guide sanding roller 3 respectively installed at both ends of the frame 1, a plurality of fixed rollers 4 rotatably connected to the frame 1, and the plurality of fixed rollers 4 are arranged flush, a plurality of linear actuators 5 are installed on the frame 1, and the linear actuators 5 can be electric cylinders, and a force sensor 6 is installed at the output end of the linear actuator 5, and the force sensor 6 can be a pressure sensor, and a mounting seat 7 is installed on the force sensor 6, and a detection wheel 8 is rotatably connected to the mounting seat 7, and the detection wheel 8 corresponds to the fixed roller 4 one by one, and the spacing between the detection wheel 8 and the fixed roller 4 is gradually reduced from the guide sanding roller 2 to the guide sanding roller 2 3, and an adjusting sanding mechanism is installed on the frame 1, and the adjusting sanding mechanism is located on the side close to the guide sanding roller 2 3.

[0021] In this embodiment, the cloth is input from the top of the guide sanding roller 2 through the guiding and bearing action of the guide sanding roller 2 and the guide sanding roller 3, passes through between the fixed roller 4 and the detection wheel 8, and then is sanded by adjusting the sanding mechanism, and finally output from the top of the guide sanding roller 2 3. Through the guiding and bearing action of the guide sanding roller 2 and the guide sanding roller 2 3, the cloth is in a horizontal state when passing through the fixed roller 4, and is always in contact with the bottom of the fixed roller 4. A plurality of fixed rollers 4 and detection wheels 8 are arranged in cooperation to form a plurality of detection mechanisms. When the cloth that is always in contact with the fixed rollers 4 generates pressure on the detection wheels 8 in one of the groups, the pressure is transmitted to the force sensor 6 by the mounting seat 7. That is, there is more fluff on the cloth here, and the fixed rollers 4 and detection wheels 8 of the subsequent groups do not need to be detected again, so as to avoid the subsequent groups of fixed rollers 4 and detection wheels 8 with a smaller spacing to press the fluff tightly, thereby making the sanding effect worse. The detection wheels 8 move downward under the drive of the linear actuator 5. When the detection wheel 8 that detects the pressure cannot detect the pressure, the detection wheels 8 of the subsequent groups rise to the initial position again, and the detection wheels 8 of the subsequent groups continue to detect the less fluff on the cloth. When a group of detection wheels 8 in the subsequent groups detects pressure, the detection wheels 8 subsequent to the detection wheel 8 here descend to avoid compacting the fluff. Therefore, by setting a plurality of detection wheels 8 and fixed rollers 4 to detect the amount of fluff, the sanding mechanism can be automatically adjusted according to the amount of fluff, thereby ultimately improving the sanding effect.

[0022] In some embodiments, in order to automatically adjust the sanding effect according to the amount of fluff, an adjusting sanding mechanism is provided, including a sanding roller 19 and a sanding roller 10. The sanding roller 19 and the sanding roller 10 are arranged in cooperation with each other. The sanding roller 19 is rotatably connected to the frame 1. A sliding frame 11 is slidably clamped on the frame 1. The sanding roller 10 is rotatably connected to the sliding frame 11. A linear actuator 12 is installed on the frame 1.

The rotating drive device 13 can be a motor. The output end of the rotating drive device 13 is transmission-connected to the sanding roller 9. A rotating drive device 14 is installed on the sliding frame 11. The rotating drive device 14 can be a motor. The output end of the rotating drive device 14 is transmission-connected to the sanding roller 10. The sanding roller 19 is driven to rotate by the rotary drive device 13, and the sanding roller 10 is driven to rotate by the rotary drive device 14. The sanding roller 19 and the sanding roller 10 cooperate to sand the cloth. When the detection wheel 8 at different positions and heights is subjected to pressure, the linear actuator 12 drives the sanding roller 10 on the sliding frame 11 to move up and down, thereby adjusting the distance between the sanding roller 19 and the sanding roller 10, so as to achieve the purpose of automatically adjusting the sanding pressure of cloth of different thicknesses.
