Description

Technical Field

[0001] The utility model belongs to the technical field of coaters, in particular to a paint film coater. Background Art

[0002] Coating, also commonly known as glue coating, is a process widely used in various industrial fields. It mainly refers to the precise coating of various forms of polymer materials, such as paste polymers, molten polymers or polymer melts, on substrates such as paper, cloth, and plastic films to prepare composite materials with specific functions. The paint film coater, as an efficient and precise coating equipment, provides strong support for this process. The paint film coater can ensure that the paint is evenly distributed during the coating process, avoiding quality problems caused by uneven distribution of the paint. By using the paint film coater, we can easily evenly coat the paint on various substrates to prepare composite materials with excellent performance to meet various application requirements.

[0003] However, there are some problems with the existing technology: when using the existing paint film applicator, the staff needs to pour the paint on the guide plate, so that the paint flows along the guide plate to the bottom of the scraper, and then the paint can be scraped onto the surface of the substrate. However, the staff often needs to coat substrates of different widths. For substrates with narrow widths, the paint often flows to both sides of the substrate, resulting in paint waste. Therefore, we propose a paint film applicator. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a paint film applicator, which limits the flow range of the paint by setting a baffle, thereby improving the applicability of the device and avoiding paint waste.

[0005] The utility model is implemented as follows: a paint film applicator comprises a base, a frame is arranged on the base, a differentiator is installed on the frame, the number of the differentiators is two, a scraper is installed between the bottoms of the two differentiators, a guide plate is installed on the frame, a bidirectional screw is movably installed inside the frame, both sides of the outer surface of the bidirectional screw are threadedly sleeved with sliding plates, a guide rod is also installed on the frame, and the sliding plate is movably sleeved on the outer surface of the guide rod, a baffle is arranged on the sliding plate for limiting the flow range of paint on the surface of the guide plate, the baffle is connected to the sliding plate by an elastic mechanism, and the baffle can be tightly attached to the surface of the guide plate through the elastic mechanism.

[0006] Optionally, the elastic mechanism includes a round pin, the round pin is movably inserted on the slide, and the baffle is fixedly connected to the bottom of the round pin.

[0007] Optionally, a spring is movably sleeved on the outer surface of the round pin, and two ends of the spring are respectively fixedly connected to the surfaces of the sliding sheet and the baffle.

[0008] Optionally, a permanent magnetic chuck is fixedly mounted on the base, and the frame is disposed on the permanent magnetic chuck.

[0009] Optionally, a release paper is laid on the permanent magnetic chuck, and the release paper is movably connected to the frame.

[0010] Optionally, a pressing plate is movably mounted on the release paper, and the pressing plate is configured to be in the shape of a square sheet.

[0011] Optionally, supporting feet are installed at the bottom of the base, and the number of the supporting feet is four, and the four supporting feet are evenly distributed at the bottom of the base.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up a bidirectional screw, a slide and a baffle, when the width of the substrate is narrow, the staff can rotate the bidirectional screw so that the two slides drive the two baffles to move toward each other, thereby reducing the distance between the two baffles. The staff pours the paint on the area between the two baffles on the surface of the guide plate. Due to the shielding effect of the baffle, the width range of the paint flowing downward is limited, thereby avoiding the waste of paint flowing to both sides of the substrate and improving the applicability of the device.

[0014] 2. By setting the round pin and the spring, and by setting the spring to a compressed state, the elastic force of the spring will generate a thrust on the baffle, so that the baffle can be tightly attached to the surface of the guide plate, thereby improving the sealing between the baffle and the guide plate, avoiding the gap between the baffle and the guide plate that causes paint to seep out, and ensuring the baffle's shielding effect on the paint.

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, a paint film applicator provided by an embodiment of the utility model includes a base 1, a frame 2 is arranged on the base 1, a differentiator 3 is installed on the frame 2, the number of the differentiators 3 is two, a scraper 4 is installed between the bottoms of the two differentiators 3, a guide plate 5 is installed on the frame 2, a bidirectional screw rod 6 is movably installed inside the frame 2, and both sides of the outer surface of the bidirectional screw rod 6 are threadedly sleeved with slides 7, a guide rod 8 is also installed on the frame 2, and the slide 7 is movably sleeved on the outer surface of the guide rod 8, a baffle 9 is arranged on the slide 7, which is used to limit the flow range of the paint on the surface of the guide plate 5, the baffle 9 is connected to the slide 7 by an elastic mechanism, and the baffle 9 can be tightly attached to the surface of the guide plate 5 through the elastic mechanism.

[0024] The staff can rotate the bidirectional screw 6 so that the two slides 7 drive the two baffles 9 to move toward or away from each other, thereby adjusting the distance between the two baffles 9. After the staff pours the paint on the surface of the guide plate 5, the two baffles 9 block the paint and limit the width range of the paint flowing downward, thereby facilitating the staff to apply paint to substrates of different width ranges, thereby improving the applicability of the device.

[0025] Furthermore, the elastic mechanism includes a round pin 10 , which is movably inserted into the slide 7 , and the baffle 9 is fixedly connected to the bottom of the round pin 10 .

[0026] Furthermore, a spring 11 is movably sleeved on the outer surface of the round pin 10, and the two ends of the spring 11 are respectively fixedly connected to the surfaces of the slide 7 and the baffle 9. By setting the spring 11 in a compressed state, due to the elastic force of the spring 11, a thrust will be exerted on the baffle 9, so that the baffle 9 can be closely attached to the surface of the guide plate 5, thereby improving the sealing between the baffle 9 and the guide plate 5, and avoiding the gap between the baffle 9 and the guide plate 5 to cause the paint to seep out.

[0027] Furthermore, a permanent magnetic chuck 12 is fixedly mounted on the base 1, and the frame 2 is arranged on the permanent magnetic chuck 12. Through the design of the permanent magnetic chuck 12, the magnetic substrate can be adsorbed to limit it, which is convenient for subsequent coating work, and has the same adsorption effect as the existing vacuum adsorption device, and can also prevent the paint from entering the vacuum adsorption hole.

[0028] Furthermore, a release paper 13 is laid on the permanent magnetic chuck 12, and the release paper 13 is movably connected to the frame 2. Through the design of the permanent magnetic chuck 12, excess paint can be taken during the coating process to prevent the paint from adhering to the permanent magnetic chuck 12, which facilitates the cleaning work of the staff.

[0029] Furthermore, a pressing plate 14 is movably mounted on the release paper 13, and the pressing plate 14 is configured in a square sheet shape. The pressing plate 14 can be made of cast iron. For a non-magnetic substrate, the worker can press the non-magnetic substrate on the bottom of the pressing plate 14, and the pressing plate 14 is subjected to the magnetic adsorption of the permanent magnetic chuck 12, so that the non-magnetic substrate can be pressed and fixed, and the coating work can also be performed.

[0030] Furthermore, four legs 15 are installed at the bottom of the base 1, and the four legs 15 are evenly distributed at the bottom of the base 1. By adjusting the four legs 15, the base 1 can be in a horizontal state, thereby ensuring that the paint is evenly coated on the substrate.

[0031] When in use, the staff can adjust the base 1 to a horizontal state through the support feet 15, and then place the substrate on the release paper 13 and at the bottom of the frame 2. If the substrate is a non-magnetic material, the staff can use the pressing plate 14 to press the substrate on the surface of the release paper 13, turn on the permanent magnetic suction cup 12 to magnetically adsorb the substrate or the pressing plate 14 to fix the substrate, and then adjust the distance between the scraper 4 and the surface of the substrate through the differentiator 3. After the adjustment is completed, the staff can adjust the distance between the two baffles 9 according to the width of the substrate. The staff can rotate the bidirectional screw 6 so that the two slides 7 drive the two baffles 9 to move toward each other, thereby reducing the distance between the two baffles 9. At the same time, due to the elastic force of the spring 11, a thrust will be generated on the baffle 9, so that the baffle 9 can be tightly attached to the surface of the guide plate 5, thereby improving the sealing between the baffle 9 and the guide plate 5. Then the staff pours the paint on the area between the two baffles 9 on the surface of the guide plate 5. Due to the shielding effect of the baffle 9, the width range of the paint flowing downward is limited, thereby avoiding the paint flowing to both sides of the substrate and causing waste, and at the same time improving the applicability of the device. The frame 2 can be made of aluminum alloy and will not be affected by magnetic force. After the paint flows to the surface of the substrate, the staff can move the frame 2 so that the scraper 4 evenly coats the paint on the surface of the substrate.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
