Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a manual coating test device. Background Technology

[0002] Coating technology involves using coating equipment to apply fluids such as adhesives to the surface of a substrate, such as a film, forming a functional film layer. Many factors in coating technology, including the size of the coated film, the amount of coating, the thickness of the coating layer, and the uniformity of the coating, all affect the film's adhesion, consistency, and transparency. Therefore, it is necessary to conduct experiments to determine multi-factor standards for coating technology in order to produce coated films that meet customer performance requirements.

[0003] The existing coating machines used for testing have the following problems: 1) The coating thickness is difficult to adjust; 2) The length of the coating machine is limited, and the length of the coated film that can be coated in a single pass is relatively short. As a result, on the one hand, the test data is limited and cannot meet the performance testing of coated films of different lengths. On the other hand, it cannot meet the large demand and the coating efficiency is low, which in turn affects the test efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a manual coating test device with adjustable coating thickness, high coating accuracy, long coating length, and high coating efficiency.

[0005] To achieve the above-mentioned technical effects, the technical solution of this utility model is: a manual coating test device, comprising:

[0006] A coating table includes a base plate and two support plates fixedly connected to the base plate. The two support plates are arranged opposite to each other along the width direction of the base plate. Each support plate is provided with a limiting groove with the slot facing upward.

[0007] A scraper is disposed above the base plate and includes a coating section and limiting sections at both ends of the coating section. The coating section is disposed between the two support plates, and the limiting sections are engaged in the limiting groove.

[0008] The scraper height adjustment assembly includes a guide member disposed on the lower surface of the base plate and a height adjustment member connected to the guide member, the height adjustment member abutting against the lower surface of the limiting section;

For example, they can refer to fixed connections, detachable connections, or integrally formed connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figure 1-4 As shown in the embodiment, a manual coating test device includes:

[0028] The coating table 1 includes a base plate 11 and two support plates 12 fixedly connected to the base plate 11. The two support plates 12 are arranged opposite to each other along the width direction of the base plate 11. The support plates 12 are provided with a limiting groove 121 with the slot opening facing upward.

[0029] The scraper 2 is located above the base plate 11 and includes a coating section 21 and a limiting section 22 at both ends of the coating section 21. The coating section 21 is located between the two support plates 12, and the limiting section 22 is engaged in the limiting groove 121.

[0030] The scraper height adjustment assembly 3 includes a guide 31 disposed on the lower surface of the base plate 11 and a height adjustment component 32 connected to the guide 31, the height adjustment component 32 abutting against the lower surface of the limiting section 22;

[0031] The scraper locking assembly 4 includes a stop member 42 rotatably connected to the guide member 31 and a locking member 41 disposed on the stop member 42; the stop member 42 is positioned above the limiting section 22 in the vertical direction, and the locking member 41 is pressed against the upper surface of the limiting section 22.

[0032] The base 6 is fixedly connected to the support plate 12 and supports the coating table 1.

[0033] With the two support plates 12 in place, the coating section 21 of the doctor blade 2 is sandwiched between the two support plates 12, and the support plates 12 restrict the doctor blade 2 from moving along the width direction of the base plate 11; the setting of the limiting groove 121 with the groove opening of the limiting groove 121 facing upward restricts the movement of the limiting section 22 and the doctor blade 2 along the length direction of the base plate 11; in summary, the cooperation of the support plates 12 and the limiting groove 121 allows the doctor blade 2 to move only in the vertical direction, that is, the thickness direction of the base plate 11, so as to adjust the distance between the doctor blade 2 and the upper surface of the base plate 11, thereby realizing the adjustable coating thickness, so as to facilitate the thickness test to detect the influence of different coating thicknesses on the film performance.

[0034] The design of the scraper height adjustment component 3 adjusts the vertical height of the scraper 2, thereby adjusting the distance between the scraper 2 and the upper surface of the base plate 11. Specifically, the guide 31 is threadedly connected to the height adjustment component 32; by rotating and twisting the height adjustment component 32, the vertical displacement of the height adjustment component 32 is achieved, thereby driving the scraper 2, which abuts against the height adjustment component 32, to move vertically, so as to adjust the distance between the scraper 2 and the base plate 11. The coating thickness can be adjusted to form adhesive layers of different thicknesses on the film surface.

[0035] After the height of the scraper 2 is adjusted, the stop member 4 is positioned above the limiting section 22 and the locking member 41 degrees is positioned on the upper surface of the limiting section 22 to fix the position of the limiting section 22 and the scraper 2.

[0036] The scraper height adjustment assembly 3 cooperates with the scraper locking assembly 4 to restrict the vertical displacement of the scraper 2. Furthermore, the height adjustment component 32 and the locking component 41 cooperate to clamp the limiting segment 22 between the height adjustment component 32 and the locking component 41, thereby restricting the vertical movement of the limiting segment 22 and the scraper 2.

[0037] like Figure 1-3As shown, in another preferred embodiment, along the length direction of the base plate 11, the base plate 11 includes a coating area 111 disposed on one side of the scraper 2 and a curing area 112 disposed on the other side of the scraper 2.

[0038] The scraper 2 is positioned above the base plate 11. One end of the film is manually pulled to move the film from the coating area 111 to the curing area 112. During the movement, the film coated with adhesive passes through the gap between the scraper 2 and the base plate 11 to achieve coating.

[0039] like Figure 4 As shown, in another preferred embodiment, the scraper 2 is a comma scraper 2; the coating section 21 is provided with a cutting edge 221, which is tangent to the parallel base plane of the base plate 11.

[0040] In this embodiment, the cutting edge 221 is the generatrix of the scraper 2 parallel to the upper surface of the base plate 11. The comma scraper 2 design, that is, the cross-sectional shape of the scraper 2 perpendicular to the width direction of the base plate 11 is comma-shaped, ensures uniform coating, facilitates cleaning and maintenance, and has a long service life.

[0041] like Figure 3 As shown, the guide member 31 is further provided with a guide hole 311, and the height adjustment member 32 passes through the guide hole 311 and abuts against the lower surface of the limiting section 22.

[0042] A guide hole 311 passes through a guide member 31 in the vertical direction; the guide hole 311 allows the height adjustment member 32, which passes through the guide hole 311, to move vertically. The height adjustment member 32 is threadedly connected to the guide hole 311; specifically, the guide hole 311 has a thread, and the height adjustment member 32 has a thread that matches the thread in the guide hole 311. Rotating the height adjustment member 32 causes it to move vertically, thereby moving the scraper 2, which abuts against the height adjustment member 32, vertically to adjust the height of the scraper 2.

[0043] like Figure 1-3 As shown, in another preferred embodiment, the stop member 42 has a C-shaped structure and is rotatably connected to the guide member 31 around the length direction of the base plate 11; the stop member 42 includes two oppositely arranged connecting rods 422 and a stop rod 421 connecting the two connecting rods 422, the two connecting rods 422 clamp the guide member 31 and are rotatably connected to the guide member 31, the locking member 41 is connected to the stop rod 421 and moves in a direction perpendicular to the rotation axis of the stop member 42.

[0044] The stop component 42 is rotatably connected to the guide component 31. When the height of the scraper 2 is adjusted to the correct position, the stop rod 421 rotates to the top of the limiting section 22 and stops the scraper 2 in the limiting section 22, thereby restricting the movement of the scraper 2 in the vertical direction. When the stop component 42 does not lock the scraper 2, the stop rod 421 is placed on the side of the limiting section 22 without interfering with the removal of the scraper 2, making it easy for the scraper 2 to be put on and taken off the coating table 1 at any time.

[0045] Furthermore, the locking member 41 is provided on the stop lever 421. When the stop lever 421 is rotated above the limiting section 22, the locking member 41 is tightened to abut against the upper surface of the limiting section 22, thereby restricting the movement of the scraper 2 in the vertical direction.

[0046] Furthermore, the stop lever 421 is provided with a locking hole 423, and the locking member 41 passes through the locking hole 423 and is connected to the stop lever 421; specifically, the locking hole 423 and the locking member 41 are threadedly connected.

[0047] like Figure 1-3 As shown, in another preferred embodiment, a film winding roller 51 connected to the base 6 is also included. The axial direction of the film winding roller 51 is in the same direction as the width direction of the base plate 11. The film winding roller 51 winds up the film to be coated.

[0048] In this embodiment, along the length of the base plate 11, the base plate 11 includes a film inlet end 113 and a film outlet end 114; the scraper 2 is disposed between the film inlet end 113 and the film outlet end 114, and divides the base plate 11 into a coating area 111 and a curing area 112.

[0049] The film roll 51 is designed to provide the film to be coated for the coating operation. The film length is not limited, and coating operations of films of different lengths can be realized.

[0050] like Figure 1-3 As shown, in another preferred embodiment, a guide roller 52 is also provided below the base plate 11. The two ends of the guide roller 52 are connected to the two support plates 12. The guide roller 52 is provided on the side of the coating area 111 away from the doctor blade 2 along the length direction of the base plate 11. The axial direction of the guide roller 52 is in the same direction as the width direction of the base plate 11.

[0051] The guide roller 52 is located below the film inlet end 113 of the base plate 11 to guide the film, allowing the film to adhere to the base plate 11 and move in.

[0052] like Figure 1-4 As shown, the operation steps of this utility model are as follows (the left and right directions mentioned below refer to the width direction of the base plate 11):

[0053] Step 1: Determine the coating thickness; Place the scraper 2 on the support plate 12, and place iron sheets of equal thickness in the gap between the scraper 2 and the base plate 11 according to the coating thickness requirements.

[0054] Step 2: Place the iron sheet in the gap between the scraper 2 and the base plate 11 on the left side, and adjust the height adjustment piece 32 on the left side until the iron sheet simultaneously abuts against the scraper 2 and the base plate 11 (this can be judged by the force with which the iron sheet moves in and out of the gap between the scraper 2 and the base plate 11).

[0055] Step 3: Place the iron sheet in the gap between the scraper 2 and the base plate 11 on the right side, and adjust the height adjustment piece 32 on the right side until the iron sheet simultaneously abuts against the scraper 2 and the base plate 11 (the force with which the iron sheet moves in and out of the gap between the scraper 2 and the base plate 11 is the same as the force in Step 2).

[0056] Step 4: Rotate the stop part 42 so that the stop rod 421 is above the limit section 22, and adjust the locking part 41 so that the locking part 41 abuts against the upper surface of the limit section 22. At this time, the scraper 2 is fixed to the coating table 1.

[0057] Step 5: The starting end of the film is passed around the guide roller 52 and adhered to the base plate 11, passing through the gap between the doctor blade 2 and the base plate 11, and then fixed in place. Adhesive is poured onto the film in the coating area 111. The film in the curing area 112 is pulled and moved towards the exit end 114. The film coated with adhesive passes through the doctor blade 2 to complete the coating operation and is cured in the curing area 112. This completes the coating process.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
