[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 to 2 , an embodiment provided by the present utility model: a gel patch preparation device with adjustable gel thickness, including a fixing frame 1. The fixing frame 1 is the basic frame of the device, providing structural support for the entire equipment. Ensure that all components are stably fixed in place to ensure the normal operation of the equipment. The fixing frame is usually made of a strong material to withstand various forces and pressures generated during operation. A support plate 1 is fixedly connected to the front side of the fixing frame 1, a motor 1 is installed on the top of the support plate 1, and the driving end of the motor 1 is fixedly connected to a rotating column 1. The motor 1 is the power source and is responsible for driving the rotating column 1. When the motor is started, its driving end drives the rotating column to rotate.

[0033] A first rotating column 3 is fixedly connected to the rear side of a first gear 4. A second rotating column 5 is rotatably connected to the left side inside a fixing frame 1. A second gear 6 is rotatably connected to the rear side of the second rotating column 5. The external teeth of the first gear 4 are meshed with the external teeth of the second gear 6. A third rotating column 7 is rotatably connected to the right side inside the fixing frame 1. A third gear 8 is fixedly connected to the rear side of the third rotating column 7. The external teeth of the second gear 6 are meshed with the external teeth of the third gear 8. A fourth rotating column 9 is rotatably connected to the right side inside the fixing frame 1. A fourth gear 10 is fixedly connected to the rear side of the fourth rotating column 9. The external teeth of the third gear 8 are meshed with the external teeth of the fourth gear 10. The external teeth of the fourth gear 10 are meshed with the external teeth of the first gear 4. The first rotating column is connected to the first gear 4, and the first gear is further meshed with the second gear 6 and the fourth gear 10 to form a complex gear transmission system, enabling the second rotating column 5, the third rotating column 7, and the fourth rotating column 9 to rotate synchronously. Through precisely designed gear ratios, the adjustment of the rotation speed and torque can be achieved to meet different operation requirements.

[0034] Hydraulic cylinders 11 are fixedly connected to both the front and rear sides of the top of the fixing frame 1. The driving end of the hydraulic cylinder 11 is fixedly connected to the top of the third rotating column 7. The hydraulic cylinder 11 is connected to the top of the third rotating column 7 and is used to control the vertical movement of the third rotating column. By adjusting the extension and retraction of the hydraulic cylinder, the position of the third rotating column can be changed, thereby adjusting the coating thickness of the gel. This design allows for flexible adaptation to gel coating operations with different thickness requirements. A glue applicator tube 12 is fixedly connected inside the fixing frame 1. The glue applicator tube 12 is installed inside the device and is responsible for evenly applying the gel onto the patch. A scraper is fixedly connected to the left side inside the fixing frame 1, and the scraper is used to remove the excess gel to ensure the uniformity and accuracy of the coating. These two components work together to ensure the quality of the gel patch. A support frame 13 is fixedly connected to the right side of the fixing frame 1. Flattening components are provided on both the front and rear sides inside the support frame 13. The flattening components can flatten the patch. The flattening components include two limiting columns 17. The patch moves leftward under the rotation of the first flattening column 15 and when it contacts the second flattening column 16, the second flattening column 16 is forced to move upward. At this time, the limiting column 17 is upwardly pressed, and the outside of the limiting column 17 is slidably connected inside the support frame 13.

[0035] The bottom of the two limiting columns 17 is rotatably connected to the second flattening column 16. A first spring is sleeved outside the limiting column 17. The first spring is compressed under force and can adapt to the thickness of different patches. One end of the first spring is fixedly connected to the bottom of the support frame 13, and the other end of the first spring is fixedly connected to the outside of the limiting column 17 and is used for flattening the patch. This ensures that the patch is flat and wrinkle-free before entering the gluing area, avoiding unevenness during gluing. A feeding plate 22 is fixedly connected to the right side of the support frame 13. The support frame 13 provides support for the feeding plate 22 and is equipped with flattening components. A second support plate is fixedly connected to the rear side of the feeding plate 22.

[0036] Reference Figures 3 to 4 Figures 3 to 4 , a conveying component is arranged on the front side of the support frame 13. The conveying component can convey the patch. The conveying component includes a second motor 14. The outside of the second motor 14 is fixedly connected to the top of the second support plate. The driving end of the second motor 14 is fixedly connected to a first flattening column 15. A first driving roller 18 is fixedly connected to the front side of the first flattening column 15. A belt 19 is sleeved on the outside of the first driving roller 18. A fixed column 20 is rotatably connected to the right side of the support frame 13. A driven roller 21 is fixedly connected to the front side of the fixed column 20. The second motor 14 drives the first flattening column 15 to rotate, and drives the driven roller 21 to rotate through the belt 19, realizing the automatic conveying of the patch.

[0037] The other end inner wall of the belt 19 is sleeved on the outside of the driven roller 21. A rotating rod 23 is rotatably connected to the right side of the support frame 13. A wheel 24 is rotatably connected to the front side of the rotating rod 23. A second spring 25 is fixedly connected to the left side of the top of the rotating rod 23. The other end of the second spring 25 is fixedly connected to the bottom of the feeding plate 22. The second spring 25 is stretched under force. A push plate 26 is slidably connected to the top of the rotating rod 23. When the rotating rod 23 rotates, the top will drive the push plate 26 to move to the right. A cam 27 is fixedly connected to the middle of the fixed column 20. The outside of the cam 27 is in contact with the outside of the wheel 24. The interaction between the cam 27 and the wheel 24 and the pulling force of the second spring 25 are used in combination to push the patch to move smoothly to the right and perform subsequent processing steps.

[0038] Working principle: First, place the fixing frame 1 in a suitable position, then place the patch on the feeding plate 22, and then start the second motor 14. Driven by the second motor 14, the first flattening column 15 rotates. During the rotation of the first flattening column 15, it will drive the first driving roller 18 to rotate. When the first driving roller 18 rotates, it drives the driven roller 21 to rotate through the belt 19. When the driven roller 21 rotates, it will drive the fixed column 20 to rotate. At this time, the cam 27 will rotate with the fixed column 20. When the cam 27 rotates, it will contact the wheel 24. The convex surface of the cam 27 will squeeze the wheel 24 to rotate, so that the rotating rod 23 rotates. When the rotating rod 23 rotates, the top will drive the push plate 26 to move to the right. At this time, the second spring 25 is stretched under force. When the smooth surface of the cam 27 contacts the wheel 24, the rotating rod 23 is no longer stressed and moves to the left. At this time, the second spring 25 is no longer stressed and resets, which can pull the push plate 26 to move to the left and push the patch on the top of the feeding plate 22 to move to the left at the same time. The patch moves to the left under the rotation of the first flattening column 15. When it contacts the second flattening column 16, the second flattening column 16 is stressed and moves upward. At this time, it squeezes the limiting column 17 upward, and the first spring is compressed under force, which can adapt to the thickness of different patches, and then flatten the patch to avoid wrinkles during gluing.

[0039] After starting motor 1-2, under the drive of motor 1-2, rotating column 1-3 rotates. When rotating column 1-3 rotates, it drives gear 1-4 to rotate. Gear 1-4 drives gear 2-6 and gear 4-10 to rotate through external teeth. At this time, rotating column 2-5 and rotating column 4-9 rotate. At the same time, under the rotation of gear 2-6 and gear 4-10, gear 3-8 rotates, thereby enabling the rotation of rotating column 3-7. When the patch enters the bottom of rotating column 3-7, the glue liquid inside the glue applicator tube 12 falls outside rotating column 3-7 and is coated on the patch by rotation. At the same time, the scraper will scrape off the excess part outside rotating column 3-7 to avoid overcoating. When a thicker coating is required, start hydraulic cylinder 11. Under the drive of hydraulic cylinder 11, rotating column 3-7 moves upward, and the glue liquid outside rotating column 3-7 will accumulate to a certain thickness, increasing a certain thickness during coating.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
