Description

Technical Field

[0001] This utility model relates to the field of coating, and more specifically, it relates to a coating machine for producing release film. Background Technology

[0002] Release film, also known as peel-off film, release film, or anti-stick film, is a specially treated thin film with low surface energy, allowing other materials (such as tapes, labels, optical films, etc.) to be easily peeled off without leaving adhesive residue. Coating machines are indeed required in the production of release film. This is because the key to release film lies in its release coating, which is typically achieved through a precision coating process.

[0003] There are many types of coating machines, with the most common being the doctor blade coating machine. A doctor blade coating machine generally includes a machine body with a gluing module, a drying module, and a winding module mounted on its trough. The gluing module typically includes a glue tank and a doctor blade. A support roller is positioned below the doctor blade. The film material passes between the support roller and the doctor blade. During this process, the glue in the glue tank slides onto the moving film material, and the doctor blade scrapes off excess glue, ensuring a suitable thickness of glue on the film. After the film coating operation is completed, a large amount of glue and solidified glue lumps remain on the doctor blade. Often, the doctor blade and glue tank need to be cleaned before production can resume. However, doctor blades are mostly fixed to the machine body, requiring removal and cleaning before reinstallation, a rather cumbersome process.

[0004] Based on the above, the purpose of this utility model is to provide a coating machine for producing release film to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a coating machine for release film production. This invention features a scraper mounted on an adjustable rotating plate. When the scraper needs cleaning, the adjusting mechanism controls the scraper to rotate upwards or to an angle suitable for worker cleaning. At this time, the side of the scraper that was originally facing the glue tank will turn away from the glue tank and face the worker due to the rotation, making it easier for the worker to clean the glue on the scraper without disassembling and reassembling the scraper, thus improving cleaning efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a coating machine for producing release film, comprising a coating machine body, wherein a glue tank, a scraper and a support roller are provided on the coating machine body, a flip plate is rotatably connected to the coating machine body, a height adjustment module is provided on the flip plate, an mounting plate is fixedly connected to the moving end of the height adjustment module, the scraper is mounted on the mounting plate, and an adjustment mechanism for controlling the angle of the flip plate is provided on the coating machine body.

[0007] By adopting the above technical solution, when the coating operation is completed and the scraper needs to be cleaned, the user controls the scraper to flip through the adjustment mechanism until the scraper flips upward or to an angle suitable for the worker to clean. At this time, the side of the scraper that was originally facing the glue tank will turn away from the glue tank and face the worker due to the flip, which makes it easier for the worker to clean the glue on the scraper. There is no need to disassemble and install the scraper, which improves the cleaning efficiency. After cleaning is completed, the scraper is flipped in the opposite direction through the adjustment mechanism until the scraper is reset.

[0008] The present invention is further configured such that: the adjustment mechanism includes two support rods respectively fixedly connected to both sides of the flip plate, the support rods on both sides are rotatably connected to the coating machine body, and a handwheel and a limiting mechanism for limiting the rotation angle of the support rods are fixedly connected to both support rods.

[0009] The present invention is further configured such that: the limiting mechanism includes a limiting block fixedly connected to the support rod; both sides of the coating machine body are slidably connected to limiting rods; springs are sleeved on the limiting rods; the two ends of the springs abut against the coating machine body and the limiting rods respectively; and the limiting block is provided with a plurality of limiting grooves for the limiting rods to be inserted.

[0010] The present invention is further configured such that a synchronizing rod is fixedly connected between the limiting rods on both sides.

[0011] The present invention is further configured such that: the height adjustment mechanism includes a plurality of micro heads fixedly connected to the flip plate, and the protruding end of the micro head is fixedly connected to the mounting plate.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This invention features a scraper mounted on an adjustable flip plate. When cleaning is required, the scraper is flipped upwards or to an angle suitable for the worker. The side of the scraper that was originally facing the glue tank will turn away from the glue tank and face the worker due to the flipping, making it easier for the worker to clean the glue on the scraper. This eliminates the need to disassemble and reassemble the scraper, thus improving cleaning efficiency. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] A coating machine for producing release film, such as Figures 1 to 2 As shown, the coating machine includes a coating machine body 1, on which a glue tank 2, a scraper 3, and a support roller 4 are installed. A flip plate 5 is rotatably connected to the coating machine body 1. A height adjustment module is provided on the flip plate 5. A mounting plate 6 is fixedly connected to the moving end of the height adjustment module. The scraper 3 is installed on the mounting plate 6. The mounting plate is provided with a mounting groove for the scraper to be inserted. The scraper is then fixed to the mounting plate by bolts. The coating machine body 1 is provided with an adjustment mechanism for controlling the angle of the flip plate 5.

[0022] Furthermore, the adjustment mechanism includes two support rods 7 that are fixedly connected to both sides of the flip plate 5. The two support rods 7 are rotatably connected to the coating machine body 1. A handwheel 8 and a limiting mechanism for limiting the rotation angle of the support rods 7 are fixedly connected to both support rods 7.

[0023] Furthermore, the limiting mechanism includes a limiting block 9 fixedly connected to the support rod 7, and limiting rods 10 slidably connected to both sides of the coating machine body 1. A spring 11 is sleeved on the limiting rod 10, and the two ends of the spring 11 abut against the coating machine body 1 and the limiting rod 10 respectively. The limiting block 9 has several limiting grooves 12 for the limiting rods 10 to be inserted. The limiting block can be annular, and the limiting grooves are arranged in a ring on the limiting block.

[0024] Furthermore, a synchronizing rod 13 is fixedly connected between the two limiting rods 10. The height of the synchronizing rod can be higher than the highest point after the scraper is flipped, so that the synchronizing rod will not hinder the adjustment of the scraper angle.

[0025] Furthermore, the height adjustment mechanism includes several micrometer heads 14 fixedly connected to the flip plate 5. The micrometer head is the head of the micrometer, which can be extended and retracted by rotating the measuring rod of the drive vehicle. The extended end (measuring rod) of the micrometer head 14 is fixedly connected to the mounting plate 6. The user can adjust the distance between the scraper and the support roller according to the micrometer head, thereby controlling the thickness of the rubber material left on the mold material.

[0026] It can also be mentioned that a space can be set up between the gluing module and the drying module, that is, behind the scraper, for workers to operate and to facilitate cleaning the scraper.

[0027] Working principle: When the coating operation is completed and the scraper 3 needs to be cleaned, the user pulls the synchronous rod 13 upward, which in turn moves the limit rods 10 on both sides upward until the limit rods 10 separate from the limit grooves 12. At this time, the user can rotate the handwheel 8 or directly flip the mounting plate upward to make the scraper 3 flip up until the scraper 3 flips to face upward or to other angles suitable for the worker to clean. At this time, release the synchronous rod 13, and the limit rods 10 on both sides insert into the corresponding limit grooves 12 under the action of gravity and spring 11, thereby preventing the flipping plate 5 from rotating. At this time, the side of the scraper 3 that was originally facing the glue tank 2 will turn away from the glue tank 2 and face the worker due to the flip, which makes it easier for the worker to clean the residual glue on the scraper 3 without disassembling and installing the scraper 3, thus improving the cleaning efficiency. After cleaning, the scraper 3 is flipped in the same way until the scraper 3 is reset.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
