Technical Field
[0001] This utility model relates to the field of coating machine technology, and in particular to a coating mechanism for a coating machine. Background Technology
[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. They coat a roll of substrate with a layer of adhesive, paint or ink with specific functions, and then dry it before cutting it into sheets or rewinding it. They use a special multi-functional coating head to achieve various forms of surface coating. The unwinding and rewinding of the coating machine are equipped with a full-speed automatic film splicing mechanism and PLC program tension closed-loop automatic control.
[0003] Currently, when a coating machine applies adhesive, the rolled substrate is transferred between the coating roller and the corresponding scraper roller. During this process, the coating roller and scraper roller rotate to roll up the adhesive and apply it to the surface of the substrate. However, in the existing technology, the distance between the coating roller and the scraper roller is not easy to adjust. When coating rolls of different thicknesses, the effect is not good, the application range is limited, and the overall production efficiency of the coating machine is reduced. Therefore, it is urgent to design a coating mechanism for a coating machine to solve the above problems. Utility Model Content

Detailed Implementation
[0040] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0041] Reference Figures 1-9 This utility model provides a coating mechanism for a coating machine, comprising:
[0042] Two side plates 1 and two machine plates 2, with first reinforcing rods 3 installed at the four corners of the two machine plates 2, and second reinforcing rods 10 installed at the four corners of the side plates 1 and the four corners of the machine plates 2.
[0043] The glue-applying roller 4 is arranged in two rows at equal distances between the two machine plates 2, and both ends of the glue-applying roller 4 are equipped with first mounting sleeves 15. A transmission component 14 is provided at one end of the upper and lower rows of first mounting sleeves 15.
[0044] The first adjustment mechanism 7, installed on one side of the machine plate 2, is used to adjust the height of the glue-applying roller 4. The first adjustment mechanism 7 includes two first slide rails 76 installed on one side of the machine plate 2, and each first slide rail 76 has a first slider 75 slidably mounted on it.

The transmission assembly 14 includes a transmission rod 16 at one end of the first mounting sleeve 15, and a rotating gear 143 is installed on one side of each transmission rod 16. One side of the machine plate 2 is equipped with a... A rotating seat 141 is rotatably connected to a first transmission gear 144 and a second transmission gear 142 on one side. The rotating gear 143, the first transmission gear 144, and the second transmission gear 142 mesh sequentially. A first chain disc 17 is fixedly installed on one side of the outer wall of the transmission rod 16 below, and a second chain is meshed on the first chain disc 17.

Due to the rotating gear 143 installed on the transmission rod 16 at one end of the first mounting sleeve 15, and through the sequential meshing of the first transmission gear 144 and the second transmission gear 142 on one side of the rotating seat 141, as well as the transmission of the first chain 17 and the second chain located on the transmission rod 16 below, the coating wheel 4 is rotated, which facilitates the rolling of the adhesive and allows the adhesive to be completely coated on the roll material.
[0045] The scraper rollers 6 are arranged in two rows at equal intervals on one side of the coating rollers 4. Each end of the scraper rollers 6 is fitted with a second mounting sleeve 19. Each end of the two second mounting sleeves 19 is provided with a second adjusting mechanism 11. The second adjusting mechanism 11 includes a fixed plate 1110 mounted on one side of the machine plate 2 and one side of the first movable plate 74. A second screw 119 is rotatably connected to each of the two fixed plates 1110. A second movable plate 115 is screwed onto each of the second screws 119. One side of the second movable plate 115 is fixedly connected to one end of each of the second mounting sleeves 19. Both the machine plate 2 and the first movable plate 74 have first movable grooves 111 for the second mounting sleeves 19 to move. Two fixing ears 116 are fixed on one of the fixed plates 1110, and a rotating shaft 118 is rotatably connected to each of the two fixing ears 116. A bevel gear 117 is fixedly installed on the outer wall and one end of the second screw 119, and a handle 112 is fixed to one end of the rotating shaft 118. A second movable groove 12 for the handle 112 to move is provided on the side plate 1. A second slide rail 113 is installed on one side of the machine plate 2 and one side of the first movable plate 74. A second slider 114 is fixedly installed on both ends of one side of the second movable plate 115 and is slidably mounted on the second slide rail 113. Rotating the handle 112 drives the rotating shaft 118 to rotate. The second screw 119 is rotated through the meshing transmission of the bevel gear 117. The second movable plate 115, which is screwed to the second screw 119, moves under the cooperation of the second slide rail 113 and the second slider 114, thereby adjusting the position of the scraper wheel 6. The scraper wheel 6 rotates to scrape off excess glue, so that the glue is evenly applied to the surface of the substrate.
[0046] To ensure stable roll material transport, refer to Figure 7 Two machine plates 2 are each equipped with a guide seat at one end near the feeding area of the coating mechanism. The top of the guide seat is rotatably connected to a second feeding roller 13, and the bottom of the guide seat is rotatably connected to a first feeding roller 8. The machine plate 2 has a through hole for the first feeding roller 8 to pass through. One end of the first mounting sleeve 15 near the feeding area of the coating mechanism and the end of the first feeding roller 8 are each equipped with a second chain disc. The two second chain discs are driven and meshed by a first chain 18. The guide seat, the first feeding roller 8 and the second feeding roller 13 are set in the feeding area, and the first feeding roller 8 is driven and connected to the coating wheel 4 through the first chain 18. This can stably guide and transmit the roll material, ensure the positional accuracy of the roll material during the coating process, and improve the processing accuracy.
[0047] To improve safety, refer to Figure 1Two protective plates 9 are installed at the ends of the two machine plates 2 near the feeding area of the glue coating mechanism. One side of one of the machine plates 2 is equipped with glue injection pipes 5 that are evenly distributed. The glue inlet end of the glue injection pipe 5 is connected to the glue equipment, and the glue outlet end of the glue injection pipe 5 is located in the middle area above the scraper wheel 6. The protective plate 9 in the feeding area can prevent operators from accidentally contacting the dangerous area and improve the safety of equipment use. The glue injection pipe 5 delivers the glue to the middle area above the scraper wheel 6, ensuring a stable and uniform glue supply, which helps to improve the glue coating effect.
[0048] Working principle: The rolled substrate enters from the feeding area of the coating mechanism of the coating machine and is guided by the second feeding roller 13 installed at the top of the guide seat and the first feeding roller 8 at the bottom. One end of the first mounting sleeve 15 near the feeding area of the coating mechanism is connected to one end of the first feeding roller 8 through the second chain and the first chain 18, which drives the first feeding roller 8 to rotate, thereby achieving stable conveying of the substrate.
[0049] The glue inlet of the glue dispensing tube 5 is connected to the glue equipment, and the glue outlet is located in the middle area above the glue scraper 6 to continuously supply glue for the glue application process.
[0050] In the glue application stage, the motor 72 starts, and the transmission wheel on its output shaft drives the transmission wheel at the drive end of the worm gear box 71 to rotate through the transmission belt 73. The output shaft of the worm gear box 71 drives the first screw 78 to rotate. The lifting seat 77, which is screwed to the first screw 78, drives the first movable plate 74 to move up and down under the cooperation of the first slide rail 76 and the first slider 75, thereby adjusting the height of the glue application wheel 4. Since the glue application wheel 4 is distributed in two rows at equal distances between the two machine plates 2, the rotating gear 143 installed on the transmission rod 16 at one end of the first mounting sleeve 15 at both ends of the rollers 4 rotates by meshing with the first transmission gear 144 and the second transmission gear 142 on one side of the rotating seat 141 in sequence, and is driven by the first chain 17 and the second chain located on the transmission rod 16 below, thereby rotating the glue application wheel 4 and rolling the glue.
[0051] Moreover, the scraper rollers 6 are also arranged in two rows at equal intervals on one side of the coating roller 4. Turning the handle 112 drives the rotating shaft 118 to rotate, and the second screw 119 is rotated through the meshing transmission of the bevel gear 117. The second movable plate 115, which is screwed to the second screw 119, moves under the cooperation of the second slide rail 113 and the second slider 114, thereby adjusting the position of the scraper rollers 6. The rotation of the scraper rollers 6 scrapes off the excess glue, so that the glue is evenly applied to the surface of the substrate.
[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
