Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a high-temperature release film coating device for automatically detecting flatness. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine can coat a roll of substrate with a layer of adhesive, paint or ink with specific functions; release film refers to a film whose surface can be distinguished. Release film does not have stickiness or has slight stickiness when in contact with specific materials under limited conditions; the coating process of release film is also carried out on a coating machine.

[0003] Before the release film is coated, its flatness needs to be tested to screen out quality problems with the release film itself (irreversible wrinkles or deformations caused by excessively high drying temperature or large temperature difference during cold plastic forming). Before the release film is tested, it is in a continuous conveying state. During this process, the release film may shift or deform due to the lack of appropriate clamping equipment, which may also cause wrinkles in the release film. This situation will increase the error of the flatness test of the release film body. Utility Model Content

[0004] This utility model discloses a high-temperature resistant release film coating device for automatic flatness detection, which aims to solve the technical problem that wrinkles or deformations caused by transportation or equipment operation before the flatness detection of the release film body lead to large errors in the detection results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-temperature release film coating device for automatically detecting flatness includes a main frame, on which a leveling module is mounted. The main frame has fixing holes, and a fixing frame is fixedly connected to each fixing hole. A laser detector is fixedly connected to one side of the fixing frame, and a connecting chamber is fixedly connected to the bottom of the fixing frame. Multiple nozzles are evenly spaced at the bottom of the connecting chamber. The leveling module includes multiple sliding rods, with thin rods fixedly connected to both ends of each sliding rod. Sliding seats are slidably connected to the outer walls of each thin rod. Springs are wrapped around the outside of each thin rod, and one end of each spring... All components are fixedly connected to corresponding sliding seats. Rotating sleeves are movably connected to the exterior of each sliding seat. The leveling module also includes two sliding frames, which are centrally symmetrical and slide on the top inner wall of the main frame. Racks are fixedly connected to the outer walls of the opposing sides of the two sliding frames. Mounting holes are provided on the top of the main frame, and rotating shafts are movably connected within these holes. Gear II is fixedly connected to the exterior of the rotating shaft, and both racks mesh with gear II. Gear I is fixedly connected to the outer wall of the end of the rotating shaft furthest from gear II, and a hydraulic system is fixedly connected to the top of the main frame. The hydraulic rod has a gear fixedly connected to its drive end, and the gear meshes with a gear. Two drive motors are fixedly connected to each of the two sliding frames, and each drive motor's output end is fixedly connected to a winding wheel. A winding rope is wrapped around the outside of each winding wheel, and the end of the winding rope away from the winding wheel is fixedly connected to a corresponding sliding seat. Each of the two sliding frames has a circular hole, and a fixed rod is fixedly connected to each of the two circular holes. Multiple rotating rods are movably connected to the outside of each of the two fixed rods, and a sliding element is fixedly connected to the end of each rotating rod away from the fixed rod. Each sliding member is slidably connected to a movable cylinder. Each of the multiple rotating rods is surrounded by a spring. One end of each spring is fixedly connected to the corresponding sliding member, and the other end is fixedly connected to the inner wall of the corresponding movable cylinder. Both ends of each sliding rod are fixedly connected to a rotating frame, and the rotating frames are movably connected to the corresponding movable cylinder. The top of the main frame is fixedly connected to a paint tank and a delivery pump. The input ends of the paint tank and the delivery pump are connected, and the output end of the delivery pump is fixedly connected to a delivery pipe. The end of the delivery pipe away from the delivery pump is connected to a connecting compartment.

[0007] Equipped with a leveling module, the hydraulic rod pulls the rack during release film transport, meshing with and rotating gear two. Gear two, in turn, drives two sliding frames to move synchronously in opposite directions. A fixed rod pulls the rotating rod, causing the movable cylinder to move synchronously, forcing both ends of the release film to be clamped between the rotating sleeves. This allows for adaptive and stable clamping of release films of different thicknesses, preventing misalignment and displacement. Simultaneously, the elasticity of spring one prevents excessive clamping force on the release film, avoiding transport difficulties and damage. Before inspection, multiple drive motors are simultaneously activated to tighten the winding rope, pulling the sliding seat to overcome the elasticity of spring two and slide it outside the thin rod. The rotating sleeve pulls the release film to expand on both sides, quickly eliminating wrinkles and maintaining the flatness of the release film. Combined with a laser detector, the quality of the release film can be automatically inspected in real time while the film surface remains flat (using the laser detector to emit a laser beam and measure the time difference of the reflected light to measure the film thickness and uniformity).

[0008] As can be seen from the above, the high-temperature resistant release film coating device for automatic flatness detection provided by this utility model can adaptively and stably clamp release films of different thicknesses through the leveling module, preventing conveying deviation and deformation. At the same time, it can stretch and smooth the release film before detection, avoiding wrinkles or loosening of the release film caused by conveying or equipment operation, thereby improving the accuracy of flatness detection of the release film body before coating.

Winding ropes 211 are wrapped around the outside of the multiple winding wheels 210, and the ends of the multiple winding ropes 211 away from the winding wheels 210 are fixedly connected to the corresponding sliding seats 218. Circular holes are opened on both sliding frames 201, and fixed rods 208 are fixedly connected to the two circular holes. Multiple rotating rods 212 are movably connected to the outside of the two fixed rods 208, and the ends of the multiple rotating rods 212 away from the fixed rods 208 are fixedly connected to sliding seats 218.

[0018] Working principle: When conveying the release film, the hydraulic rod 202 is activated to pull the rack 203. Through the meshing of the rack 203 and gear 205, the rotating shaft 204 and gear 206 are rotated. Through the meshing of the two racks 207 and gear 206, the two sliding frames 201 are moved synchronously in opposite directions. The fixed rod 208 pulls the rotating rod 212, causing the rotating rod 212 to rotate and change its angle. The spring 214 and the sliding element 213 drive the movable cylinder 215 to move synchronously, so that the sliding rod 217 drives the sliding seat 218 to clamp the two ends of the release film between the rotating sleeve 219. This can provide adaptive and stable clamping when conveying release films of different thicknesses and specifications, preventing misalignment. The position is offset, and the elasticity of spring 214 can prevent excessive clamping force on the release film, thus preventing transportation difficulties and damage. The conveying pump 5 is started to pump the paint in the paint tank 3 into the connecting chamber 8 through the conveying pipe 4, and spray it evenly through the nozzle 9 to coat the release film. Before the test, multiple drive motors 209 are started simultaneously to rotate the winding wheel 210, tighten the winding rope 211, and pull the sliding seat 218 to slide outside the thin rod 220 against the elasticity of spring 221. By rotating the sleeve 219, the release film is pulled to expand on both sides, quickly eliminating wrinkles and keeping the release film flat. The laser detector 7 can inspect the release film body while keeping the film surface flat.
