Description

Technical Field

[0001] This application relates to the field of coating equipment technology, specifically to a coating roller mechanism. Background Technology

[0002] Coating machines are mainly used for coating processes of materials such as films and paper. They are used to coat the surface of raw materials with coating liquids with specific functions, such as adhesives, paints, and inks, then dry them, and finally roll up the finished products.

[0003] Chinese patent CN217473947U discloses a back coating mechanism of a gantry-type multifunctional composite coating machine, including a material trough, a coating roller, a paper pressing roller, a doctor blade, and a traction guide roller. A portion of the coating roller is immersed in the liquid in the material trough. The blade of the doctor blade is in contact with the coating roller. The doctor blade includes a mounting frame and a blade mounted on the mounting frame. The mounting frame has a collar on the side opposite to the side where the blade is mounted. The collar is rotatably sleeved on the doctor blade mounting roller. The collar has an adjusting component with a rotatable front-to-back adjustment knob. The front-to-back adjustment knob is threadedly connected to the mounting frame. A doctor blade adjusting cylinder is fixed on the doctor blade mounting roller, and the piston rod of the doctor blade adjusting cylinder is hinged to the adjusting component.

[0004] The aforementioned patents still have the following drawbacks:

[0005] In the aforementioned patent, a portion of the coating roller is immersed in the liquid in the material tank. The coating process involves the coating roller rotating so that the coating liquid adheres to the coating roller. Through the cooperation of the coating roller and the doctor blade, the coating liquid is applied to the film or paper to be coated. During this process, if the speed of the coating roller increases, the coating liquid in the material tank may be carried out by the coating roller. That is, if the speed of the coating roller is too fast, the coating liquid in the material tank will splash out. If the coating liquid splashes out and drips onto the film or paper to be coated, the coating will not be uniform and will affect the stability of the coating. Utility Model Content

[0025] Specifically, the frame 3 includes a first side plate 301 and a second side plate 302; the first side plate 301 and the second side plate 302 are arranged opposite to each other; the traction roller 1, the guide roller 2, the coating plate 4, the coating roller 5 and the material tube 7 are all arranged between the first side plate 301 and the second side plate 302; the width direction of the first side plate 301 and the second side plate 302 is the first direction, and the axial direction of the traction roller 1, the guide roller 2 and the coating roller 5 is the second direction.

[0026] The coating plate 4 and the coating roller 5 are arranged opposite to each other, and a coating gap is formed between the coating plate 4 and the coating roller 5; a number of liquid outlet holes are opened on the side of the coating plate 4 near the coating gap, and the side of the coating plate 4 away from the coating roller 5 is connected to the material pipe 7.

[0027] In one embodiment of this application, in order to ensure that the coating liquid is evenly distributed on the coating plate 4, so that the coating liquid can be evenly coated on the film or paper, a plurality of liquid outlet holes are evenly arranged along the second direction, and the spacing between adjacent liquid outlet holes is consistent.

[0028] More specifically, the feed tube 7 may have only one guide hole, or it may have a number of guide holes that match the number of liquid outlet holes. The feed tube 7 and the coating plate 4 may be connected by a metal hose, with one end of the metal hose connected to the guide hole and the other end connected to the coating plate 4. In one embodiment of this application, the feed tube 7 is located below the coating plate 4. In order to enable the coating liquid to move from bottom to top, a pump body may be provided to pump the coating liquid in the feed tube 7 to the coating plate 4.

[0029] The film or paper to be coated is guided into the coating gap by the traction roller 1 and the guide roller 2, and the coating process is carried out in the coating gap.

[0030] The coating roller 5 is connected to the first drive component 8;

[0031] For example, the first driving component 8 can be an electric motor, a gasoline engine, or a diesel engine. In one embodiment of this application, the first driving component 8 is selected as an electric motor.

[0032] The gap adjustment assembly 6 is connected to the coating plate 4. The gap adjustment assembly 6 includes a first guide rail, a second guide rail, a first guide member, and a second guide member. The first guide member is adapted to the first guide rail, and the second guide rail is adapted to the second guide member. The first guide rail is located at the end of the coating plate 4 near the first side plate 301. The second guide rail is located at the end of the coating plate 4 near the second side plate 302.

The second guide member is connected to the end of the coating plate 4 near the second side plate 302 and is slidably connected to the second guide rail.

[0033] By setting the gap adjustment component 6, which is connected to the coating plate 4, the relative position of the coating plate 4 and the coating roller 5 is adjusted. The relative position of the coating plate 4 and the coating roller 5 affects the size of the coating gap, thereby causing a change in the coating amount. That is, this application can adjust the coating amount of the coating liquid in the coating process by using the gap adjustment component 6.

[0034] The coating roller mechanism described in this application connects the feed pipe 7 to the coating plate 4 and provides a liquid outlet hole on the side of the coating plate 4 near the coating gap. The coating roller 5 is partially immersed in the feed tank and adjusted to connect the feed pipe 7 to the coating plate 4. During the coating process, the coating liquid in the feed pipe 7 flows out from the liquid outlet hole of the coating plate 4. Under the rolling of the coating roller 5, the coating liquid is coated onto the film or paper that has passed through the coating roller 5. Since the coating plate 4 has several liquid outlet holes that are evenly distributed, the coating liquid on the coating plate 4 is evenly distributed, thereby ensuring uniform coating of the coating liquid and guaranteeing the stability of the coating process.

[0035] Furthermore, the gap adjustment component 6 can manually adjust the gap between the coating roller 5 and the coating plate 4. To make the gap adjustment component 6 more automated, the gap adjustment component 6 also includes a second drive component, which is connected to the guide component.

[0036] For example, the second drive component can be an electric motor, a gasoline engine, or a diesel engine. In one embodiment of this application, the second drive component is an electric motor.

[0037] Furthermore, the traction roller 1 is used to pull the film or paper to be coated. In order to make the coating roller mechanism described in this application more automated, the coating roller mechanism of this application also includes a third drive member 9, which is connected to the traction roller 1.

[0039] Furthermore, it also includes a control component 10, which is electrically connected to the first drive component 8, the second drive component, and the third drive component 9, respectively.

[0040] For example, the control element 10 may be a PLC (Programmable Logic Controller), a PAC (Programmable Automation Controller), or a PID controller (Proportional-Integral-Derivative Controller); in one embodiment of this application, a PLC (Programmable Logic Controller) is selected as the control element 10.

[0041] Furthermore, in order to protect the frame 3 of the coating roller mechanism of this application, the coating roller mechanism of this application also includes a first side plate cover 11 and a second side plate cover 12; the first side plate cover 11 covers the side of the first side plate 301 away from the second side plate 302; the second side plate cover 12 covers the side of the second side plate 302 away from the first side plate 301.

[0042] Furthermore, the distance between the first side plate 301 and the second side plate 302 is 2000mm to 2300mm.

[0043] Furthermore, the height of the first side plate 301 is 2000mm to 2100mm; the height of the second side plate 302 is 2000mm to 2100mm.
