Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to an experimental device for combining multiple coating methods. Background Technology

[0002] With the development of increasingly diverse coated products and the diversification of societal demands, new material coating manufacturers need to update their product processes. Different coating methods are required to meet diverse coating requirements. Before achieving mature, large-scale production, multiple process verifications of various coating methods are necessary to ultimately determine the final coating process of the coating machine. Therefore, experiments on multiple coating methods are required to verify the coating process. Existing coating method experimental equipment generally includes several types, such as microgravure coating mechanisms, slot extrusion mechanisms, and comma blade coating mechanisms. Specifically, during the experiment, the corresponding coating mechanism is switched on the machine frame to verify the coating process. On the one hand, the need for switching during the experiment makes the process cumbersome; on the other hand, verifying combined coating methods requires multiple devices to be connected in series, resulting in low efficiency and cumbersome operation in the multi-type coating process experiment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] See Figures 1-3 As shown in the embodiment of this utility model, a multi-coating method combination experimental device is proposed, including a frame 1 and multiple coating guide rollers 2 mounted on the frame 1. The coating guide rollers 2 are used to guide the movement of the coating substrate. One of the coating rollers serves as a power roller, and the multiple coating guide rollers can switch the movement direction and position of the coating substrate according to the experimental requirements of the coating process. Simultaneously, a micro-recessed coating mechanism 3, a slot extrusion coating mechanism 4, and a comma-shaped doctor blade coating mechanism 5 are mounted on the frame 1. The specific installation positions are determined according to the positions of the multiple coating guide rollers 2, ensuring that the coating substrate can pass through the positions of the three coating mechanisms after switching movement directions.

[0023] The slit extrusion coating mechanism 4 includes a support plate 42 fixed on the frame 1, a transverse adjustment mechanism 41 and a slit coating assembly 46 mounted on the transverse adjustment mechanism 41; thereby, the transverse adjustment mechanism 41 enables the slit coating assembly 46 to be switched between working and non-working positions.

[0024] The comma-shaped doctor blade coating mechanism 5 includes a material storage tank 51 detachably mounted on the frame 1, and a comma-shaped doctor blade coating assembly 52 slidably mounted on the frame 1 and located on one side of the material storage tank 51. The frame 1 is equipped with a first adjusting cylinder 53 for pushing and pulling the comma-shaped doctor blade coating assembly 52 to move. The material storage tank 51 can be installed when the comma-shaped doctor blade coating assembly 52 is in the working state and removed when it is not in the working state. The first adjusting cylinder 53 switches the comma-shaped doctor blade coating assembly 52 between the working position and the non-working position.

[0025] Therefore, the slit coating assembly 46 and the comma blade coating assembly 52, which are used for coating operations, do not need to be disassembled. Only their positions need to be adjusted. This avoids the cumbersome disassembly and assembly process and avoids the need to readjust the precision after disassembly and assembly.

[0026] By integrating three coating mechanisms into a single frame 1, and with adjustable working and non-working states, at least the following coating process experiments can be performed:

[0027] 1. When the slit coating assembly 46 and the comma blade coating assembly 52 are in the non-working position, guide the coating substrate to carry out the micro-groove coating process experiment at the micro-groove coating mechanism 3.

[0028] 2. When the comma doctor blade coating assembly 52 is in the non-working position, guide the coating substrate to the slot coating assembly 46 to carry out the slot coating process experiment.

[0029] 3. When the comma doctor blade coating assembly 52 is in the non-working position, the coating substrate is guided to pass through the micro-grooving coating mechanism 3 and the slit coating assembly 46 in sequence to realize the combined process experiment of micro-grooving coating process and slit coating process.

[0030] 4. When the slit coating assembly 46 is in the non-working position, guide the coating substrate to the comma doctor blade coating assembly 52 to conduct the comma doctor blade coating process experiment.

[0031] 5. When the slit coating assembly 46 is in the non-working position, guide the coating substrate through the micro-grooving coating mechanism 3 and the comma doctor blade coating assembly 52 in sequence to realize the combined process experiment of micro-grooving coating process and comma doctor blade coating process.

[0032] This enables the experimental efficiency of various coating processes; among them, the slit coating assembly 46 and the comma blade coating assembly 52 both adopt mature technologies.

[0033] Specifically, the microgravure coating mechanism 3 includes a first support 31 fixed on the frame 1 and a microgravure coating blade 32 rotatably mounted on the first support 31. A second adjusting cylinder 33 is rotatably mounted on the first support 31. The telescopic rod of the second adjusting cylinder 33 is rotatably connected to the microgravure coating blade 32. The angle of the microgravure coating blade 32 is adjusted by the second adjusting cylinder 33 to adjust the coating thickness. Simultaneously, a third adjusting cylinder 34 is fixedly mounted on the frame 1. A first coating roller 35 that cooperates with the microgravure coating blade 32 is mounted on the telescopic rod of the third adjusting cylinder 34. Two second coating rollers 36 are mounted on the frame 1, positioned above the first coating roller 35 and spaced apart. The height of the first coating roller 35 is adjusted by the third adjusting cylinder 34, thereby adjusting the gap between it and the second coating rollers 36, further adjusting the coating thickness.

[0034] A fourth adjusting cylinder 37 and a first adjusting plate 38 are rotatably mounted on the frame 1. The telescopic rod of the fourth adjusting cylinder 37 is rotatably connected to the first adjusting plate 38. Two second coating rollers 36 are spaced apart and mounted on the first adjusting plate 38 at the ends away from the fourth adjusting cylinder 37. The angle of the first adjusting plate 38 is adjusted by the fourth adjusting cylinder 37, thereby further adjusting the gap between the second coating rollers 36 and the first coating rollers 35.

[0035] Meanwhile, two second coating rollers 36 are slidably mounted on the first adjusting plate 38. The first adjusting plate 38 is equipped with adjusting screws 39 for adjusting the distance between the second coating rollers 36 and the first coating rollers 35. The adjusting screws 39 are used to achieve small displacement adjustment of the second coating rollers 36 to meet the adjustment requirements of the micro-gravure coating thickness in different coating processes.

[0036] Specifically, the transverse adjustment mechanism 41 includes a slide rail 43 spaced on the support plate 42 and a sliding plate 44 slidably mounted on the slide rail 43. A slot coating assembly 46 is mounted on the sliding plate 44. The support plate 42 is provided with a fifth adjusting cylinder 45 for pulling the sliding plate 44 to slide. The fifth adjusting cylinder 45 pushes the sliding plate 44 to move relative to the slide rail 43, thereby realizing the adjustment of the working position and non-working position of the slot coating assembly 46.

[0037] Meanwhile, a receiving groove 54 is also provided on the sliding plate 44 below the slit coating assembly 46 and the comma scraper coating assembly 52. ​​The receiving groove 54 enables the recycling of coating slurry, preventing it from falling into the micro-concave coating mechanism 3 and causing pollution.

[0038] It should be noted that each coating process is relatively mature. This embodiment mainly integrates multiple coating processes for corresponding experiments, such as coating combination thickness and coating speed. For parts involving specific coating process implementation structures not mentioned, existing technologies can be used. With the combined experimental equipment proposed in this embodiment, experiments on at least five coating process types can be carried out, improving experimental efficiency and reducing cumbersome operations in the experimental process.
