Description

Technical Field

[0001] This utility model relates to the technical field of coating machine accessories, and in particular to a coating machine head adjustment component. Background Technology

[0002] Coating equipment is mainly used for surface coating processes of films, paper, etc. This equipment coats a layer of adhesive, paint or ink with specific functions onto the surface of a rolled coating substrate, and then rewinds it after drying. In order to facilitate coating of raw materials with different coating requirements, existing coating heads are mostly equipped with adjustment components such as spokes and screws to facilitate the lifting and lowering adjustment of the coating roller.

[0003] After the coating roller is adjusted, it is supported by friction generated by the screw and fixed structure such as the frame. The coating roller is heavy, which makes the connection between the screw and the fixed structure have high pressure, causing the screw to wear and be damaged easily, thus shortening the service life of the device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a coating head adjustment assembly, including a frame, a slider slidably connected to the inner side of the frame, a lead screw rotatably connected to the outer side of the slider, the lead screw and the frame being threaded together, a spoke wheel fixedly connected to one end of the lead screw, a drive motor fixedly connected to the outer side of the slider on one side, a coating roller fixedly connected to the output end of the drive motor, a rotating rod rotatably connected to the outer side of the coating roller, a push block rotatably connected to the outer side of the rotating rod, a first spring fixedly connected to one side of the push block, a limit frame fixedly connected to the outer side of the first spring, and the limit frame and the push block being slidably connected; this step involves setting the lead screw, rotating rod, and push block... The device consists of a block, a first spring, and a limiting frame. In use, rotating the lead screw, through the threaded connection between the lead screw and the frame, causes the lead screw to drive one end of the slider. The slider then moves the coating roller to a suitable height, facilitating the coating of raw materials of different thicknesses and materials. As the coating roller moves downwards, it pushes one end of the rotating rod away from the others. The rotating rod then pushes the push block away from each other. The push block compresses the first spring, ensuring that the spring's reaction force continuously pushes the push block. The push block then pushes the rotating rod, which further supports the coating roller, reducing the pressure on the lead screw, thus reducing wear and tear, making it less prone to damage, and extending the device's service life.

[0005] In one embodiment of this utility model, a lifting screw is threadedly connected to the inner side of the slider, and a scraper is rotatably connected to the outer side of the lifting screw. A groove is formed on the inner side of the scraper. By setting up the lifting screw, scraper, and groove, when the coating roller rotates to coat the raw material, the lifting screw can be rotated, and the lifting screw drives the scraper to move to a suitable height. Through the contact between the scraper and the coating on the upper side of the raw material, it is easy to scrape up the excess coating, so that the excess coating can be pushed into the inner side of the groove for collection, which is convenient for subsequent recycling, thus improving the convenience of using the device.

[0006] In one embodiment of this utility model, a connecting hose is connected to the inner side of the scraper, and the connecting hose is connected to the groove. By setting the connecting hose, when excess paint enters the inner side of the groove, the connecting hose can be connected to an external driving structure such as a pump to suck out the paint accumulated in the inner side of the groove, so that excess paint is less likely to accumulate and overflow in the inner side of the groove, thus improving the stability of the device.

[0007] In one embodiment of this utility model, an inclined frame is fixedly connected to the inner side of the groove, and the inclined frame is used in conjunction with the connecting hose. This step, by setting the inclined frame, allows the paint entering the inner side of the groove to be further guided by the inclined surface of the frame, so that it can be gathered near the connecting hose, thereby making the discharge of paint more convenient and improving the ease of use of the device.

[0008] In one embodiment of this utility model, a damper is fixedly connected to the inner side of the limiting frame. One end of the damper is fixedly connected to the push block, and the damper works in conjunction with the first spring. By setting the damper, when the drive motor drives the coating roller to rotate, if it vibrates, the vibration can be transmitted to the damper and the first spring through the rotating rod and the push block. The first spring absorbs the vibration, and the damper consumes the vibration, thereby reducing the vibration of the coating roller and making the rotation of the coating roller more stable, thus improving the stability of the device.

[0009] In one embodiment of this utility model, a friction pad and a magnetic strip are fixedly connected to the inner side of the frame. Both the friction pad and the magnetic strip are used in conjunction with the slider. This step, by setting the friction pad and the magnetic strip, causes the friction pad to be squeezed when the slider moves up and down, thereby increasing the friction coefficient between the friction pad and the slider. The magnetic strip is used to attract and fix the slider, thereby making the position of the slider more stable after adjustment, which further reduces the pressure on the lead screw and improves the stability of the device operation.

[0010] In one embodiment of this utility model, a lifting rod is fixedly connected to the outside of the slider, and a second spring is fixedly connected to one end of the lifting rod. One end of the second spring is fixedly connected to the frame. This step, by setting the lifting rod and the second spring, ensures that when the slider moves, the lifting rod moves downward synchronously. The lifting rod applies force to the second spring, which, under its own contraction, further supports the lifting rod and the slider, further reducing the pressure on the lead screw and improving the stability of the device.

[0011] In one embodiment of this utility model, the slider is an I-shaped block, and the slider and the frame are slidably connected. This step, by setting the slider so that its two protruding ends, which are similar to the I-shaped block, are close to the two sides of the frame, further restricts the lifting trajectory of the slider and improves the stability of the device.

[0012] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0013] The coating head adjustment assembly described in this utility model comprises a lead screw, a rotating rod, a push block, a first spring, and a limiting frame. In use, rotating the lead screw, through the threaded connection between the lead screw and the frame, causes the lead screw to drive one end of a slider. The slider then moves the coating roller to a suitable height, facilitating the coating of raw materials of different thicknesses and materials. As the coating roller descends, it pushes one end of the rotating rod away from the other, which in turn pushes the push block away from the other. The push block compresses the first spring, ensuring that the spring's reaction force continuously pushes the push block. The push block then pushes the rotating rod, which further supports the coating roller, reducing the pressure on the lead screw, thus reducing wear and tear, making it less prone to damage, and extending the service life of the device.

[0014] The coating head adjustment assembly described in this utility model, by setting up a lifting screw, a scraper, and a groove, allows the lifting screw to be rotated when the coating roller rotates to coat the raw material. The lifting screw drives the scraper to move to a suitable height, and the scraper contacts the coating on the upper side of the raw material, thereby facilitating the scraping of excess coating. This allows the excess coating to be pushed into the groove for collection, facilitating subsequent recycling and improving the ease of use of the device. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Reference Figures 1 to 5 As shown, a coating head adjustment assembly of this utility model includes a frame 1. A slider 2 is slidably connected to the inner side of the frame 1, and a lead screw 3 is rotatably connected to the outer side of the slider 2. The lead screw 3 is threadedly connected to the frame 1. A spoke wheel 4 is fixedly connected to one end of the lead screw 3. A drive motor 5 is fixedly connected to the outer side of the slider 2 on one side. A coating roller 6 is fixedly connected to the output end of the drive motor 5. A rotating rod 7 is rotatably connected to the outer side of the coating roller 6. A push block 8 is rotatably connected to the outer side of the rotating rod 7. A first spring 9 is fixedly connected to one side of the push block 8. A limit frame 10 is fixedly connected to the outer side of the first spring 9. The limit frame 10 and the push block 8 are slidably connected. This step involves setting the lead screw 3, rotating rod 7, and push block 8... When in use, the first spring 9 and the limiting frame 10 are connected by rotating the lead screw 3. Through the threaded connection between the lead screw 3 and the frame 1, the lead screw 3 drives one end of the slider 2, which in turn drives the coating roller 6 to move to a suitable height so that it can coat raw materials of different thicknesses and materials. When the coating roller 6 moves down, it pushes one end of the rotating rod 7 away from each other. The rotating rod 7 pushes the push block 8 away from each other, and the push block 8 squeezes the first spring 9. The reaction force of the first spring 9 can continuously push the push block 8. The push block 8 pushes the rotating rod 7, which further supports the coating roller 6, thereby reducing the pressure on the lead screw 3, reducing its wear, making it less prone to damage, and extending the service life of the device.

[0024] Reference Figure 1 and Figure 5As shown, a lifting screw 11 is threadedly connected to the inner side of the slider 2, and a scraper 12 is rotatably connected to the outer side of the lifting screw 11. A groove 13 is provided on the inner side of the scraper 12. By setting up the lifting screw 11, scraper 12 and groove 13, when the coating roller 6 rotates to coat the raw material, the lifting screw 11 can be rotated, and the scraper 12 is moved to a suitable height by the lifting screw 11. Through the contact between the scraper 12 and the coating on the upper side of the raw material, it is easy to scrape up the excess coating, so that the excess coating can be pushed into the inner side of the groove 13 for collection, so as to facilitate subsequent recycling and improve the convenience of the device.

[0025] Reference Figure 5 As shown, a connecting hose 14 is connected to the inner side of the scraper 12, and the connecting hose 14 is connected to the groove 13. By setting the connecting hose 14, when excess paint enters the inner side of the groove 13, the connecting hose 14 can be connected to an external driving structure such as a pump to suck out the paint accumulated inside the groove 13, so that excess paint is less likely to accumulate and overflow inside the groove 13, thus improving the stability of the device.

[0026] Reference Figure 5 As shown, an inclined frame 15 is fixedly connected to the inner side of the groove 13. The inclined frame 15 and the connecting hose 14 are used together. By setting the inclined frame 15, the paint entering the inner side of the groove 13 can be further guided by the inclined surface of the inclined frame 15 so that it can be gathered near the connecting hose 14, thereby making the paint discharge more convenient and improving the ease of use of the device.

[0027] Reference Figure 4 As shown, a damper 16 is fixedly connected to the inner side of the limiting frame 10. One end of the damper 16 is fixedly connected to the push block 8. The damper 16 works in conjunction with the first spring 9. By setting the damper 16, when the drive motor 5 drives the coating roller 6 to rotate, once it vibrates, it can be transmitted to the damper 16 and the first spring 9 through the rotating rod 7 and the push block 8. The first spring 9 absorbs the vibration, and the damper 16 consumes the vibration, thereby reducing the vibration of the coating roller 6 and making the rotation of the coating roller 6 more stable, thus improving the stability of the device.

[0028] Reference Figure 3As shown, a friction pad 17 and a magnetic strip 18 are fixedly connected to the inner side of the frame 1. Both the friction pad 17 and the magnetic strip 18 are used in conjunction with the slider 2. This step, by setting the friction pad 17 and the magnetic strip 18, ensures that the friction pad 17 is squeezed when the slider 2 moves up and down, thereby increasing the friction coefficient between the friction pad 17 and the slider 2. The magnetic strip 18 is used to attract and fix the slider 2, making the adjusted position of the slider 2 more stable, thereby further reducing the pressure on the lead screw 3 and improving the stability of the device operation.

[0029] Reference Figure 1 and Figure 3 As shown, a lifting rod 19 is fixedly connected to the outside of the slider 2, and a second spring 20 is fixedly connected to one end of the lifting rod 19. One end of the second spring 20 is fixedly connected to the frame 1. This step, by setting the lifting rod 19 and the second spring 20, ensures that when the slider 2 moves, the lifting rod 19 will move downwards synchronously. The lifting rod 19 applies force to the second spring 20, so that the second spring 20, under its own contraction, further supports the lifting rod 19 and the slider 2, further reducing the pressure on the lead screw 3 and improving the stability of the device.

[0030] Reference Figure 3 As shown, the slider 2 is a block similar to an I-shaped block, and the slider 2 is slidably connected to the frame 1. This step, by setting the slider 2 so that its two protruding ends, which are similar to an I-shaped block, are close to the two sides of the frame 1, further restricts the lifting trajectory of the slider 2 and improves the stability of the device.

[0031] Working principle: First, the paint conveying assembly is set on the upper side of the frame 1, and the discharge end of the paint conveying assembly is set on the upper side of the coating roller 6. Rotating the lead screw 3, through the threaded connection between the lead screw 3 and the frame 1, causes the lead screw 3 to drive one end of the slider 2, which in turn drives the coating roller 6 to move to a suitable height, so that it can coat raw materials of different thicknesses and materials. When the coating roller 6 moves down, it pushes one end of the rotating rod 7 away from each other, and the rotating rod 7 pushes the push block 8 away from each other. The push block 8 squeezes the first spring 9, so that the reaction force of the first spring 9 can continuously push the push block 8. The push block 8 pushes the rotating rod 7, and the rotating rod 7 further supports the coating roller 6. When the slider 2 moves, it will simultaneously drive the lifting rod 19 to move down, and the lifting rod 19 will apply force to the second spring 20. The second spring 20, under its own contraction, will further support the lifting rod 19 and the slider 2, thereby reducing the pressure on the lead screw 3, thus reducing its wear and making it less prone to damage.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
