Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a coating machine with a conveying and correction structure. Background Technology

[0002] A coating machine is a precision industrial device that uniformly, continuously, and controllably coats a substrate surface with a liquid or slurry material that has a specific function. Its core working principle is to use a high-precision coating head to adhere the coating material to the substrate, which is moving at a constant speed, with a preset thickness and width.

[0003] In the prior art, the patent announcement number CN220720314U discloses a sheet coating and laminating machine including a main board, the surface of which has a first groove, and multiple sets of moving rollers are connected in the first groove. The left end of the main board is connected to a frame, and a roller coating mechanism is connected in the frame.

[0004] The substrate to be treated is conveyed into the coating machine by the action of the conveyor rollers for coating operations. However, in actual operation, the substrate conveyed into the coating machine is often prone to lateral or longitudinal displacement due to various factors. This displacement not only affects the smooth progress of the coating process but also leads to uneven distribution of the paste coating on the substrate surface, resulting in uneven coating. To address this, a coating machine with a conveyor correction structure is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a coating machine with a conveying and correction structure to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating machine with a conveying and correction structure, comprising a coating machine frame, a protective cover fixedly installed on one side of the coating machine frame, a coating roller rotatably installed inside the coating machine frame, a conveying mechanism installed on one side of the coating machine frame, the conveying mechanism comprising a conveying frame fixedly installed on one side of the coating machine frame and a bidirectional threaded rod rotatably installed on the coating machine frame, a guide rod fixedly installed below the bidirectional threaded rod, a movable frame slidably installed on the guide rod, a screw nut fixedly installed on the movable frame, the screw nut being threaded onto the bidirectional threaded rod, and the two sets of threads on the bidirectional threaded rod having opposite directions, a detection mechanism fixedly installed on the other side of the coating machine frame, a positioning sleeve fixedly installed on the movable frame, a strong spring provided inside the positioning sleeve, a top rod slidably installed inside the positioning sleeve, a correction plate fixedly installed at the end of the top rod, a worm gear rotatably installed inside the protective cover, and a worm wheel fixedly installed at the end of the bidirectional threaded rod, with the worm wheel meshing with the worm gear.

[0007] Preferably, a motor is fixedly installed on one side of the conveyor frame, and a guide roller and a drive roller are rotatably installed inside the conveyor frame. A synchronous gear is fixedly installed at the end of the drive roller, and the output end of the motor is fixedly installed on the drive roller.

[0008] Preferably, the bidirectional threaded rod is connected to the movable frame via a screw nut, one end of the powerful spring is connected to the bottom of the positioning sleeve, and the other end of the powerful spring is connected to one end of the top rod.

[0009] Preferably, the detection mechanism includes a stand fixedly installed on the other side of the coating machine frame, a detection cylinder fixedly installed on the stand, an alarm fixedly installed at one end of the detection cylinder, a push-button switch fixedly installed inside the detection cylinder, and the power cord of the alarm connected to the push-button switch, a spring seat slidably installed inside the detection cylinder, a telescopic rod fixedly installed on the spring seat, a tension spring sleeved on the telescopic rod, and a guide wheel installed at the end of the telescopic rod.

[0010] Preferably, a through hole is provided at the other end of the detection cylinder, and the telescopic rod extends out of the detection cylinder through the through hole.

[0011] Preferably, one end of the tension spring is connected to the spring seat, and the other end of the tension spring is connected to the end of the detection cylinder.

[0012] Preferably, the telescopic rod is movably installed inside the detection cylinder via a spring seat, and the telescopic rod is aligned front and back with the push-button switch.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, when the sheet material being fed to the coating machine deviates, the powerful spring is compressed. As the sheet material continues to move towards the coating machine, the powerful spring gradually drives the correction plate to return to its original position, correcting the originally deviated sheet material and ensuring that the coating can be evenly applied to the surface of the sheet material. Furthermore, rotating the worm gear drives the worm wheel to rotate, which in turn drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the screw nut to displace, thereby adjusting the distance between the movable frames so that the correction plate is positioned precisely on both sides of the sheet material, thus achieving the correction operation for materials of different widths.

[0014] 2. In this application, the guide rollers abut against both sides of the discharged sheet material. When the sheet material passes through the coating roller without being straightened, the offset sheet material will exert pressure on the guide rollers, causing the telescopic rod to move into the detection cylinder. During the movement of the telescopic rod into the detection cylinder, the spring seat will apply force to the push-button switch, triggering the switch and activating the alarm power. In this way, when the sheet material passes through the coating roller without being straightened, a timely warning can be issued to the user so that the user can reject defective products.

[0017] 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.

[0018] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a coating machine with a conveying and correction structure, including a coating machine frame 1, a protective cover 2 fixedly installed on one side of the coating machine frame 1, a coating roller 3 rotatably installed inside the coating machine frame 1, a conveying mechanism 4 installed on one side of the coating machine frame 1, and a detection mechanism 5 fixedly installed on the other side of the coating machine frame 1.

[0019] Specifically, during operation, the sheet material is positioned on the guide roller 402. After the motor 403 is started, it drives the drive roller 404 to rotate, thereby conveying the sheet material into the coating machine. The conveying mechanism 4 can convey the sheet material into the coating machine and correct its deviation. The detection mechanism 5 can detect whether the sheet material entering the coating machine is misaligned, thus improving product quality.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the conveying mechanism 4 includes a conveying frame 401 fixedly installed on one side of the coating machine frame 1 and a bidirectional threaded rod 407 rotatably installed on the coating machine frame 1. A guide rod 411 is fixedly installed below the bidirectional threaded rod 407. A movable frame 410 is slidably installed on the guide rod 411. A screw nut 406 is fixedly installed on the movable frame 410, and the screw nut 406 is threaded onto the bidirectional threaded rod 407. The two sets of threads on the bidirectional threaded rod 407 are in opposite directions. A positioning sleeve 413 is fixedly installed on the movable frame 410. A strong spring is provided inside the positioning sleeve 413. Spring 415, a top rod 414 is slidably installed inside the positioning sleeve 413, a correction plate 405 is fixedly installed at the end of the top rod 414, a worm gear 408 is rotatably installed inside the protective cover 2, a worm wheel 409 is fixedly installed at the end of the bidirectional threaded rod 407 and the worm wheel 409 meshes with the worm gear 408, a motor 403 is fixedly installed on one side of the conveyor frame 401, a guide roller 402 and a drive roller 404 are rotatably installed inside the conveyor frame 401, a synchronous gear 412 is fixedly installed at the end of the drive roller 404, and the output end of the motor 403 is fixedly installed on the drive roller 404.

[0021] Specifically, when the sheet material being fed into the coating machine shifts, the strong spring 415 is compressed. As the sheet material continues to move towards the coating machine, the strong spring 415 drives the correction plate 405 to gradually return to its original position, correcting the shifted sheet material and ensuring that the coating is evenly applied to the sheet material.

[0022] Furthermore, rotating the worm gear 408 will cause the worm wheel 409 to rotate; the rotation of the worm wheel 409 will cause the bidirectional threaded rod 407 to rotate; the rotation of the bidirectional threaded rod 407 will cause the lead screw nut 406 to move, thereby adjusting the distance between the movable frames 410 so that the correction plate 405 is exactly on both sides of the plate, so as to correct the material of different widths.

[0023] like Figure 2 and Figure 5 As shown, the detection mechanism 5 includes a stand 502 fixedly installed on the other side of the coating machine frame 1. A detection cylinder 501 is fixedly installed on the stand 502. An alarm 504 is fixedly installed at one end of the detection cylinder 501. A push-button switch 503 is fixedly installed inside the detection cylinder 501, and the power cord of the alarm 504 is connected to the push-button switch 503. A spring seat 505 is slidably installed inside the detection cylinder 501. A telescopic rod 507 is fixedly installed on the spring seat 505. A tension spring 506 is sleeved on the telescopic rod 507. A guide wheel 508 is installed at the end of the telescopic rod 507. A through hole is opened at the other end of the detection cylinder 501, and the telescopic rod 507 extends out of the detection cylinder 501 through the through hole.

[0024] Specifically, the guide roller 508 abuts against both sides of the discharged sheet material. When the sheet material attempts to pass through the coating roller 3 without being effectively corrected, the offset of the sheet material exerts additional pressure on the guide roller 508. This pressure forces the connected telescopic rod 507 to move inward toward the detection cylinder 501. As the telescopic rod 507 gradually moves inward toward the detection cylinder 501, the spring seat 505 mounted on the telescopic rod 507 also moves accordingly, applying a certain pressure to the push-button switch 503 located in its path. When this pressure reaches a certain level, the push-button switch 503 is pressed, thereby activating the power supply to the alarm 504. Once activated, the alarm 504 will emit an alarm signal, promptly reminding the user to pay attention to the status of the sheet material. In this way, when uncorrected sheet material passes through the coating roller 3, the user can be quickly notified and take appropriate measures to promptly remove these defective products, ensuring the smooth operation of the production process and the stability of product quality.

[0025] Working principle: During operation, the sheet material is positioned on the guide roller 402. After starting the motor 403, it drives the drive roller 404 to rotate, thereby conveying the sheet material into the coating machine. Rotating the worm gear 408 drives the worm wheel 409 to rotate, which in turn drives the double-threaded rod 407 to rotate. The double-threaded rod 407 then moves the screw nut 406, adjusting the distance between the movable frames 410 so that the correction plate 405 is positioned precisely on both sides of the sheet material. When the sheet material shifts inside the coating machine, the strong spring 415 is compressed. As the sheet material continues to move towards the coating machine, the strong spring 415 gradually resets the correction plate 405, correcting the shift and ensuring the coating is evenly applied to the sheet material. The coated board will be discharged from the coating machine. The guide roller 508 abuts against both sides of the discharged board. When the board passes through the coating roller 3 without being corrected, the offset board will press the guide roller 508, forcing the telescopic rod 507 to move into the detection cylinder 501. When the telescopic rod 507 moves into the detection cylinder 501, the spring seat 505 will apply pressure to the button switch 503, causing the button switch 503 to be pressed and the alarm 504 to be powered on. This will promptly remind the user when the board that has not been corrected passes through the coating roller 3, so that the user can reject the defective products.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
