Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to an automatic closed-loop coating system. Background Technology

[0002] An automatic closed-loop coating system refers to a coating process in which coating parameters are adjusted in real time through a feedback mechanism to ensure the consistency and stability of coating quality. Specifically, the automatic closed-loop coating system monitors various parameters (such as areal density and coating thickness) in real time during the coating process through a detection device, compares these parameters with preset targets, and then automatically adjusts the working state of the coating device through a controller to achieve precise control. An automatic closed-loop coating system typically includes components such as a controller, a coating device, a detection device, and a drying device.

[0003] The coating system provided by Chinese Utility Model Patent CN215997321U is used to coat a first side of a strip, the strip having a second side opposite to the first side. The coating system includes an adjusting member, a coating adsorption roller, and a coating head. The adjusting member can adsorb the second side of the strip passing through it, and is used to adjust the position of the strip along a first direction. The coating adsorption roller is located downstream of the adjusting member and can adsorb the second side of the strip passing through it. The coating head is used to coat the first side of the strip adsorbed on the coating adsorption roller. By configuring the above coating system, the first direction is the width direction of the strip. During strip transport, the adjusting member and the coating adsorption roller only contact the second side of the strip, without damaging the slurry layer on the first side of the strip. The adjusting member can adjust the position of the strip along its width direction, i.e., adjust the lateral position of the strip, thereby ensuring the coating accuracy of the coating head and improving the coating quality.

[0004] In the processing of substrates such as films, paper, and fabrics, an automatic closed-loop coating system is required for coating. However, the coating rollers in existing automatic closed-loop coating systems are mostly fixed to the system with bolts. When it is necessary to replace or repair the coating rollers, it is difficult to disassemble them quickly and conveniently, thus affecting the performance of the automatic closed-loop coating system. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic closed-loop coating system that allows for quick and convenient disassembly of the coating roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting a positioning component and a connecting component, moves the spring so that it is no longer under force and begins to stretch, causing the four wedge blocks to move relative to each other. This allows the positioning block to slide within the positioning groove until the four wedge blocks contact each other. At this point, the spring stops stretching, and the connecting block is moved out of the receiving groove, completing the disassembly. Compared with the prior art, this utility model has a simple and reasonable structure, ingenious design, and can quickly and conveniently disassemble the coating roller body, with better performance.

[0015] 2. This utility model, by setting up a moving component, starts a servo motor, causing the output shaft of the servo motor to drive the bidirectional lead screw to rotate, causing the two moving blocks to move away from the connecting rod and the connecting block until the side of the moving block contacts the side of the support plate. At this time, the connecting block moves out of the receiving groove. Using the servo motor as the driving source can improve the automation level of the automatic closed-loop coating system. Furthermore, by using the electrical signal control of the servo motor, the moving position of the moving block can be controlled so as to replace the coating roller body.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: an automatic closed-loop coating system, including an automatic closed-loop coating system body 1, a positioning component 2, and a connecting component 3; the automatic closed-loop coating system body 1 includes a machine body 101 and a coating roller body 102; the coating roller body 102 is connected to the machine body 101 through the positioning component 2; the positioning component 2 includes a receiving groove 201, a positioning groove 202, a positioning block 203, and a spring 204; the coating roller body 102 has symmetrically opened receiving grooves 201 on both sides; eight positioning grooves 202 are opened in a circular array in the receiving grooves 201; the positioning block 203 is inserted into the positioning groove 202 and connected to the machine body 101 through the connecting component 3; two springs 204 are arranged in a linear array in the receiving grooves 201, and one end of the spring 204 is fixedly connected to the inner wall of the receiving groove 201;

[0029] The connecting component 3 includes a connecting rod 301, a wedge block 302, and a connecting block 303; the two connecting rods 301 are symmetrically arranged on the body 101 via the moving component 4; the four wedge blocks 302 are arranged in a ring array in the receiving groove 201, and the wedge blocks 302 are fixedly connected to the other end of the spring 204; the connecting block 303 is fixedly connected to the end of the connecting rod 301; the wedge blocks 302 have a frustum-shaped structure, and the four wedge blocks 302 have an arc-shaped surface on the opposite side; the connecting block 303 has a pyramid-shaped structure, and the inclined surface of the connecting block 303 slides in contact with the inclined surface of the wedge blocks 302; the four wedge blocks 302 and the connecting block 303 constitute a complete cuboid structure.

[0030] This invention, by setting a positioning component 2 and a connecting component 3, allows the spring 204 to relax and begin to stretch through the moving component 4, causing the four wedge blocks 302 to move relative to each other. This allows the positioning block 203 to slide within the positioning groove 202 until the four wedge blocks 302 contact each other. At this point, the spring 204 stops stretching, and the connecting block 303 is moved out of the receiving groove 201, completing the disassembly. Compared with the prior art, this invention has a simple and reasonable structure, ingenious design, and can quickly and conveniently disassemble the coating roller body 102, with good performance.

[0031] In a preferred embodiment, the moving component 4 includes a support plate 401, a fixed plate 402, a sliding groove 403, a bidirectional lead screw 404, a moving block 405, and a servo motor 406. Two support plates 401 are symmetrically fixed to the body 101, and are connected by the fixed plate 402. The bottom surface of the fixed plate 402 has a sliding groove 403. The bidirectional lead screw 404 passes through the fixed plate 402 and is rotatably connected to the inner wall of the sliding groove 403 via a rotating shaft A. Two moving blocks 405 are symmetrically slidably disposed within the sliding groove 403, and are rotatably connected to the connecting rod 301 via a rotating shaft B. The bidirectional lead screw 404 is threadedly connected to the moving block 405. The servo motor 406 is fixed to one of the support plates 401 via a motor mount, and its output end is fixedly connected to the end of the bidirectional lead screw 404. When the four wedge blocks 302 are in contact with each other, the side of the positioning block 203 remains within the positioning groove 202.

[0032] This invention, by setting up a moving component 4, and by starting a servo motor 406, causes the output shaft of the servo motor 406 to drive the bidirectional lead screw 404 to rotate, causing the two moving blocks 405 to move the connecting rod 301 and the connecting block 303 away from each other until the side of the moving block 405 contacts the side of the support plate 401. At this time, the connecting block 303 moves out of the receiving groove 201. By using the servo motor 406 as a driving source, the automation level of the automatic closed-loop coating system body 1 can be improved. Furthermore, by using the electrical signal control of the servo motor 406, the moving position of the moving block 405 can be controlled so as to replace the coating roller body 102.

[0033] Working principle: During replacement, firstly, the servo motor 406 is started, causing the output shaft of the servo motor 406 to drive the bidirectional lead screw 404 to rotate. This causes the two moving blocks 405 to move the connecting rod 301 and the connecting block 303 away from each other, causing the spring 204 to relax and begin to extend. This causes the four wedge blocks 302 to move relative to each other, allowing the positioning block 203 to slide within the positioning groove 202 until the four wedge blocks 302 contact each other. At this point, the spring 204 stops extending. Finally, the side of the moving block 405 contacts the side of the support plate 401. At this point, the connecting block 303 moves out of the receiving groove 201. The disassembly of the coating roller body 102 is then completed. During installation, the servo motor 406 is controlled so that its output shaft drives the bidirectional lead screw 404 to rotate in opposite directions. This causes the two moving blocks 405 to move the connecting rod 301 and the connecting block 303 relative to each other. This causes the inclined surface of the connecting block 303 to press against the inclined surface of the wedge block 302, causing the four wedge blocks 302 to move away from each other. This causes the positioning block 203 to slide in opposite directions within the positioning groove 202, causing the spring 204 to contract under force until it reaches its maximum contraction limit. At this point, the installation of the coating roller body 102 is completed.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
