Description

Technical Field

[0001] The utility model relates to the field of coating machines, in particular to a rolling knife type hydrogel coating machine. Background Art

[0002] The rolling knife hydrogel coater is a special equipment used to evenly coat hydrogel on various substrate surfaces. This equipment is usually used in medical, hygiene products and other applications that require precise coating to ensure that the product has a high-quality coating surface and consistent coating thickness.

[0003] The prior art has the following defects: during use, the existing roller-type hydrogel coater needs to use a roller to evenly distribute the coating material on the surface of the object to be coated, and the surface of the roller will gradually wear out due to contact and friction with the hydrogel during long-term operation. The wear will cause the surface of the roller to become uneven, affecting the uniformity and quality of the coating. The roller needs to be disassembled and assembled regularly. The common disassembly and assembly method is to use tools to twist the bolts multiple times. If the bolts or tools are lost, they cannot be subsequently disassembled and assembled. Secondly, some of the existing loading boxes are installed on the fixed frame by manual transportation. Since some of the loading boxes are simply installed and used, they will still fall over or fall off if a collision occurs. Therefore, a roller-type hydrogel coater is proposed to solve the above problems. Utility Model Content

Too much elaboration, the top of the processing table 1 is fixedly connected with a fixing frame 5, the fixing frame 5 mainly supports the entire slider 7 and the turntable 8, the inner wall of the fixing frame 5 is penetrated and threadedly connected with a threaded rod 6, the inner wall of the fixing frame 5 matches the thread pattern of the threaded rod 6, and the threaded rod 6 can move in the inner wall thread of the fixing frame 5, the bottom end of the threaded rod 6 is rotatably connected with the slider 7, the middle part of the slider 7 is rotatably connected with the turntable 8, the left end of the turntable 8 is connected with the existing transmission device, and the turntable 8 can generate a rotation hydrogel evenly distributed on the surface of the material to be coated, refer to Figure 4 The inner wall of the turntable 8 is provided with an adjustment mechanism, and the right end of the adjustment mechanism is fixedly connected with a contact plate 11. There are two groups of contact plates 11, and the two groups of contact plates 11 bring the fixing blocks 12 closer to each other. The fixing blocks 12 can be used to fix the connecting shaft 13. The inner wall of the contact plate 11 is fixedly connected with the fixing block 12, and the outer wall of the fixing block 12 contacts the connecting shaft 13. The right end of the connecting shaft 13 is fixedly connected with a roller 14. The rotational movement of the roller 14 can ensure that the coating material is evenly distributed on the surface of the object to be coated, and the coating thickness can be controlled in the prior art.

[0033] Reference Figure 1 , Figure 5 and Figure 6 The top of the mounting frame 3 is fixedly connected with an extension plate 15, and the top of the extension plate 15 is elastically connected to a limit plate 17 through a positioning spring 16. The limit plate 17 is an inclined surface. When the inclined surface is squeezed, the limit plate 17 will slide along the inner wall of the extension plate 15. The side wall of the loading box 4 is fixedly connected with a T-shaped frame 18. The shape of the T-shaped frame 18 matches the inner wall of the extension plate 15, so that the T-shaped frame 18 and the extension plate 15 can be plugged to initially position the loading box 4. A limit groove 19 is provided at the top of the T-shaped frame 18, and the top of the extension plate 15 is connected to the limit plate 17. One end of the positioning spring 16 is fixedly connected. When the limit plate 17 moves upward, the positioning spring 16 will be stretched. When resetting, the elastic force of the positioning spring 16 is used to reset the limit plate 17. The other end of the positioning spring 16 is fixedly connected to the inner side wall of the limit plate 17. The limit plate 17 passes through and is slidably connected to the inner wall of the extension plate 15. The limit plate 17 is inserted into the inner wall of the limit groove 19. The lower end of the limit plate 17 contacts the surface of the T-shaped frame 18, where the surface refers to the right end side wall of the T-shaped frame 18 and the top of the T-shaped frame 18.

[0034] Reference Figure 1-Figure 3 The slider 7 is slidably connected to the inner wall of the fixing frame 5 .

[0035] Reference Figure 3 and Figure 4 The adjusting mechanism includes a bidirectional screw rod 9, which has two different sections of threads, allowing the connecting blocks 10 to move closer to or apart from each other. The bidirectional screw rod 9 passes through and is rotatably connected to the inner wall of the turntable 8. The outer wall of the bidirectional screw rod 9 is threadedly connected to the connecting block 10. The inner wall of the connecting block 10 is provided with a pattern matching the bidirectional screw rod 9, which allows the connecting block 10 to move along the threads of the bidirectional screw rod 9. The right end of the connecting block 10 is fixedly connected to the left end side wall of the contact plate 11, and the connecting block 10 is slidably connected to the inner wall of the turntable 8, and the inner wall of the contact plate 11 contacts the outer wall of the connecting shaft 13.

[0036] Working principle: First, when the roller 14 needs to be disassembled and replaced, it is only necessary to rotate the two-way screw rod 9 counterclockwise to separate the connecting block 10 and the contact plate 11 from each other, and to separate the contact plate 11 and the outer wall of the fixed block 12 and the connecting shaft 13, and quickly release the limit on the connecting shaft 13 and the roller 14. When the roller 14 needs to be installed, it is only necessary to place the connecting shaft 13 between the contact plates 11, so that the opening on the connecting shaft 13 corresponds to the direction of the fixed block 12, and then rotate the two-way screw rod 9 clockwise to bring the connecting block 10 and the contact plate 11 closer to each other, so that the roller 14 can be quickly installed without the need to use additional tools for disassembly and assembly. If the position of the roller 14 needs to be adjusted, it is only necessary to rotate the threaded rod 6 clockwise to move the slider 7, turntable 8, contact plate 11, connecting shaft 13 and roller 14 downward, and control the height of the roller 14 to achieve the adjustment of the coating thickness. When it needs to be adjusted again, it is only necessary to rotate the threaded rod 6 counterclockwise.

[0037] When the feeding box 4 needs to be disassembled, it is only necessary to pull the limit plate 17 upwards and stretch the positioning spring 16 to separate the positioning spring 16 from the limit slot 19, and then move the feeding box 4 and the T-shaped frame 18 to the left to separate the T-shaped frame 18 and the inner wall of the extension plate 15. Finally, release the limit plate 17 and use the reverse elastic force of the positioning spring 16 to restore the limit plate 17. When the roller 14 needs to be installed, it is only necessary to connect the T-shaped frame 18 with the extension plate 15, and let the right end of the T-shaped frame 18 squeeze the inclined surface of the limit plate 17, so that the limit plate 17 moves upward and stretches the positioning spring 16. When the limit plate 17 coincides with the limit slot 19, use the reverse elastic force of the positioning spring 16 to restore the limit plate 17 and plug it into the inner wall of the limit slot 19.

[0038] During use of the device, the processing table 1, the mounting frame 3 and the loading box 4 only need to be used according to the prior art, and no further elaboration is made here for the prior art.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
