Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of printing equipment, and more particularly to a coating machine. Background Art

[0002] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the present disclosure, and should not necessarily be considered as an admission or any form of suggestion that the information constitutes relevant technology that has been known to ordinary technicians in this field.

[0003] The coating machine fixes the printing screen on the metal screen frame for the production of the screen. In the related art, the coating of the photosensitive adhesive is all done by using a horizontal hanging plate. During the coating process, due to the horizontal setting, the excess photosensitive adhesive is collected on one side of the hanging plate. A blocking mechanism needs to be set on the side of the screen to prevent the photosensitive adhesive from flowing out of the side of the screen. However, the screen is the coated product, not a fixed component. It needs to be fed into the coating work surface and then taken out. Therefore, the side of the screen cannot ensure perfect sealing, causing the photosensitive adhesive to flow out from the gap, or overflow the hanging plate after being squeezed and return to the coated screen, resulting in uneven coating and affecting the quality of the screen.

[0004] In addition, the clamping structure of the coating machine adopts hydraulic type to fix the screen. The main reason is the transformation of horizontal coating machines or printing equipment, which is mainly to reduce the space occupied and improve efficiency. However, the clamping parts of the hydraulic structure are in the vertical coating machine. Due to the vertical adjustment, the hydraulic structure will be affected by gravity, making it difficult to control the clamping distance. It is easy to cause unstable clamping or excessive clamping force, which affects the stability of subsequent processes and the integrity of the screen. Summary of the Invention

The process of gluing on both sides at the same time improves work efficiency.

[0048] In one embodiment, in order to further improve the stability of the transmission device and better position the screen during use, there are two columns 201 on the same side, and the screen is generally set between the two columns 201. The top of the column 201 is fixed by the motor 205 mounting end plate. The opposite sides of the two columns 201 are notched.

[0049] In one embodiment, there are two columns 201 on the same side, and the top is fixed by the end plate of the motor 205. There are notches on the opposite sides of the two columns 201. The main synchronous wheel 202, the slave synchronous wheel 203, the fixed wheel 206 and the synchronous belt 207 are all arranged inside the column 201, and the transmission base 208 is installed on the synchronous belt 207 through the notch on the column 201.

[0050] In one embodiment, a toothed belt fixing plate adjustment seat 211 is provided on the transmission base 208 near the outer side of the synchronous belt 207. A toothed belt pressure plate 212 is provided on the toothed belt fixing plate adjustment seat 211. The toothed belt pressure plate 212 can press the synchronous belt 207 together with the main synchronous pulley 202 or the slave synchronous pulley 203 on the outer side of the synchronous belt 207 to ensure the transmission stability of the synchronous belt 207. At the same time, the toothed belt pressure plate 212 can also adjust the pressure state to ensure that the synchronous belt 207 is in a reasonable transmission tension state, ensuring a maximum service life.

[0051] In one embodiment, in order to ensure that the screen can be stably clamped by the clamping profile 210 during the clamping process, a guide plate 213 is provided on one side of the bottom of the clamping profile 210, and the guide plate 213 is inclined toward the outer side of the clamping notch.

[0052] In one embodiment, a dual-axis guide rail 307 is provided on the inner surface of the side panel 301, and the sizing flipping bracket 303 is set on the dual-axis slide rail through a dual-axis slider, and the relative clamping adjustment of the two sets of sizing flipping mechanisms is realized by the clamping cylinder 308. The driving end of the clamping cylinder 308 is connected to the dual-axis slider, and one side of the sizing flipping fixed plate 304 is set on the sizing flipping bracket 303 through a flipping rotating pin 309, and the other side is connected and fixed to the driving end of the flipping cylinder 310 on the sizing flipping bracket 303. The dual-axis slider is driven by the clamping cylinder 308, so that the upper flipping bracket can realize clamping displacement.

[0053] In one embodiment, in order to ensure that the arc-shaped sizing device 306 remains horizontal during the flipping process, the flipping rotating pin 309 and the driving end connection node of the flipping cylinder 310 are at the same horizontal position, and the flipping cylinder 310 is driven longitudinally to realize the sizing flipping fixed plate 304 to drive the upper flipping profile to flip and adjust, which is beneficial to the flatness of the glue coating.

[0054] In one embodiment, the clamping cylinder 308 is laterally arranged on the inner side of the side plate 301, and the clamping cylinder 308 of the flipping profile is adjusted on both sides to operate synchronously to ensure that the left and right sides and the opposite sides operate synchronously and smoothly. The driving end of the clamping cylinder 308 is connected to the dual-axis slider to drive and adjust the relative clamping adjustment of the two sets of sizing flipping structures.

[0055] In one embodiment, in order to better use the gluing work with screens of different specifications, a clamping adjustment nut 311 is provided on the outer side of the sizing fixed profile 302. The end of the clamping adjustment nut 311 passes through the sizing fixed profile 302 and contacts the sizing flip profile 305 to adjust the clamping distance of the sizing flip profile 305.

[0056] In one embodiment, Figure 9 As shown, the frame base 1 includes a welded base frame 101, and a mesh clamping lower profile 102 corresponding to the upper clamping frame structure is provided in the middle position of the welded base frame 101. A mesh frame lower clamping bracket 103 is provided on the side of the mesh clamping lower profile 102. The height of the mesh frame lower clamping bracket 103 is lower than the mesh clamping lower profile 102, and U-shaped bayonet holes are formed at both ends, so that the screen can be pushed in along one side of the mesh frame lower clamping bracket 103 and stuck in the U-shaped opening to ensure the stability of the bottom of the screen.

[0057] In one embodiment, the profile 210 of the clamping net of the transmission component is installed on the synchronous belt 207 for transmission to avoid excessive deviation. A clamping frame fixing mechanism is provided on the welding chassis, such as Figure 10-12 As shown, the clamping frame fixing mechanism is horizontally arranged. In actual use, the telescopic cylinder 104 is installed vertically. The clamping frame fixing mechanism includes a telescopic cylinder 104 installed on the lower profile 102 of the clamping screen. The end of the telescopic cylinder 104 is fixed to the upper clamping frame mechanism through the screen frame 5 clamping and fixing block 105. The driving end of the telescopic cylinder 104 is connected to the screen frame 5 clamping and fixing block 105 through a first curved arm 106. The top of the screen frame 5 clamping and fixing block 105 is connected to the screen frame clamping top wheel 108 through a second curved arm 107. The wheel surface of the screen frame clamping top wheel 108 faces directly below the upper clamping frame mechanism. The first curved arm 106 and the second curved arm 107 can achieve adaptive adjustment to prevent the screen 5 from rigidly contacting the upper framing mechanism during the clamping process, thereby preventing deformation. The design of the curved arms can avoid malfunctions caused by hard contact.

[0058] In one embodiment, the arc loader is a hanging plate with an arc surface, and the arc surface area forms a storage area. During the coating process, the storage area can store excess photosensitive glue in the storage area to prevent the photosensitive glue from flowing back onto the coated screen and affecting the quality of the screen.

[0059] When the coating machine is in use, the screen is first pushed in from one side of the clamping bracket 103 under the screen frame, and is stuck in the U-shaped opening to keep the bottom of the screen stable. The motor 205 is started to drive the clamping profile 210 on the screen to move downward. At the same time, the telescopic cylinder 104 is retracted and the clamping profile 210 is stuck on the top of the screen, so that the screen frame clamping top wheel 108 is pressed down on the upper surface of the screen. Then the sizing device assembly 3 is fixed on the guide rail of the column 201 through the scraper moving assembly to achieve up and down movement. In this process, the distance between the arc hanging plate and the screen is adjusted by the clamping cylinder 308 according to the thickness of the screen. During the gluing process, the angle of the arc feeder is adjusted by adjusting the flip cylinder 310, so that the excess photosensitive glue is promptly returned to the storage area after the gluing is completed. The equipment adopts a vertical structure and works by gluing on both sides at the same time to improve work efficiency and ensure the quality of the screen.
