Description

Technical Field

[0001] The utility model relates to the technical field of car cover coating, in particular to a slit-type coating device for car cover with a film head switching function. Background Art

[0002] Slit coating technology is an advanced wet coating method. Its core lies in evenly coating the coating liquid on the moving substrate by precisely controlling the gap of the coating head. This technology is widely used in automotive cover coating due to its high speed, high efficiency and high quality coating effect.

[0003] For example, a coating die structure and a slit coating device disclosed in the Chinese patent application publication number CN118788555A, the existing device is provided with multiple groups of slit dies, and the multiple groups of slit dies can alternately approach or move away from the coating substrate under the drive of the rotating assembly to coat the coating substrate, and then on a production line, different slit dies can be switched to coat the coating substrate, and different functional coatings can be sequentially coated on the coating substrate to improve the coating efficiency. However, in actual application of the existing device, after the die in the existing device is switched, a large amount of coating will be attached to the surface of the die of the previous group. If it is not cleaned, it is easy to hinder the switching work in the subsequent switching, and at the same time, a bulge will be generated between the die and the coating roller, resulting in the problem of difficulty in coating work. In addition, as the coating work continues, the slit die will wear, and the multiple groups of slit die groups in the device are in a relatively fixed connection mode, which makes it difficult to replace the slit die in time, which easily leads to the problem of reduced coating efficiency of the car cover. Therefore, in view of the drawbacks of the existing device, we urgently need to improve a slit-type coating device for car covers with a film head switching function. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Example 1: Please refer to Figure 1-Figure 5 The utility model provides a technical solution: a slit coating device for car covers with a film head switching function, comprising a coating machine body 1, a coating roller group 2 for coating is arranged inside the coating machine body 1, a driving adjustment device 31 is arranged in the coating machine body 1, a rotating frame 32 is arranged at the output end of the coating machine body 1, a slit film head group 33 is arranged in the rotating frame 32, and a slit film head cleaning mechanism 4 is arranged in the coating machine body 1, which can clean each group of film heads in the slit film head group 33 to avoid interference with the coating work when switching the film head.

[0026] The slit membrane head cleaning mechanism 4 comprises a cleaning component 41 for cleaning the membrane head and a recovery component 42 for recovering the coating generated during the cleaning.

[0027] Furthermore, the cleaning assembly 41 includes a driving motor 411 and a limiting rod 413. The driving motor 411 is arranged outside the coating machine body 1. A threaded rod 412 is arranged on the output shaft of the driving motor 411. The limiting rod 413 is arranged inside the coating machine body 1. The threaded rod 412 is externally threadedly connected to a slider 414. The slider 414 is internally threadedly connected to an adjusting screw 415. An arc-shaped cleaning plate 416 for cleaning the surface of the membrane head is arranged at the bottom of the adjusting screw 415. It is convenient to scrape off the paint attached to the surface of the membrane head to avoid interference with the subsequent switching of the membrane head.

[0028] Furthermore, a through hole is provided in the slider 414 for the limiting rod 413 to pass through, and the arc-shaped cleaning plate 416 can contact the membrane head at the corresponding position by adjusting the adjusting screw 415. This facilitates scraping and cleaning the membrane head surface at different positions, thereby improving the cleaning effect.

[0029] Furthermore, the recycling component 42 includes an electric pump 421 and a support frame 422. An absorption pipe 423 and an output pipe 425 are arranged outside the electric pump 421. A suction head 424 for absorbing the coating material generated during cleaning is arranged on the side of the absorption pipe 423 away from the electric pump 421. A recycling frame 426 is slidably arranged in the coating machine body 1. A handle 427 is arranged outside the recycling frame 426. It is convenient to absorb the scraped paint and absorb it into the recycling frame 426 for unified recycling treatment later.

[0030] Furthermore, a connection hole for the absorption tube 423 to pass through is provided inside the support frame 422, and the absorption tube 423 is arranged in a telescopic manner, and the suction head 424 faces the outside of the membrane head, so as to realize stable and effective recovery of the coating.

[0031] Example 2: Please refer to Figure 6-Figure 7 In combination with the first embodiment, it is further obtained that the rotating frame 32 is provided with an installation component 5 for quickly installing the membrane head in the slit membrane head group 33, and the installation component 5 has a connecting pipe 51, which is arranged inside the rotating frame 32, and a slide bar 52 is slidably arranged in the connecting pipe 51, a pressing column 53 is arranged outside the slide bar 52, and a first spring 54 is sleeved outside the slide bar 52. It is convenient to quickly install and disassemble the membrane head in the slit membrane head group 33.

[0032] Furthermore, the first spring 54 is arranged between the pressing column 53 and the rotating frame 32, and a connecting groove is provided at the corresponding position of the membrane head in the slit membrane head group 33 and the pressing column 53. This facilitates the fixing of the membrane head position and avoids the situation that the slit membrane head group 33 can only be replaced as a whole when a single group of membrane heads is worn.

[0033] In actual operation, the car cover to be coated can be placed inside the coating machine body 1. The car cover is coated using the coating roller group 2. To ensure the coating quality, the driving adjustment device 31 is operated to rotate the rotating frame 32 so that the film head in the slit film head group 33 is aligned with the car cover, thereby achieving more precise coating. After switching, part of the coating material will accumulate outside the film head. To avoid interference with subsequent coating, first turn the adjusting screw 415 to move the arc cleaning plate 416 up and down so that the arc cleaning plate 416 contacts the outer surface of the film head. After contact, turn on the drive motor 411 to rotate the threaded rod 412. Under the limit of the limit rod 413, the slider 414 moves outside the threaded rod 412 to drive the arc cleaning plate 416 to scrape off the coating material attached to the outside of the membrane head. Turn on the electric pump 421 to generate suction. Under the action of the absorption tube 423 and the suction head 424, the coating material generated during scraping is absorbed, and the coating material can be transported to the inside of the recovery frame 426 through the output pipe 425. After the processing work is completed, pull the handle 427 to take out the recovery frame 426, and uniformly recycle the accumulated coating material inside. Under the action of the slit membrane head cleaning mechanism 4, it can be ensured that the membrane head is switched more smoothly and the problem of coating material waste can be avoided. When the membrane head in the slit membrane head group 33 is greatly worn, the slide bar 52 can be pulled to make the pressure column 53 lose the pressure on the membrane head, and then the corresponding membrane head can be removed for replacement. After the replacement is completed, align the pressure column 53 with the connection groove of the membrane head, release the slide rod 52, and under the action of the first spring 54, the pressure column 53 will return to the initial position and squeeze the membrane head to complete the replacement process, thereby improving the coating efficiency.

[0034] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
