Description

Technical Field

[0001] This utility model relates to the technical field of coating machines, specifically to a coating machine thickness adjustable mechanism. Background Technology

[0002] A coating machine is a specialized piece of equipment used to uniformly coat liquid or semi-solid materials (such as coatings, adhesives, and battery slurries) onto the surface of a substrate. It is widely used in lithium batteries, photovoltaics, optical films, and packaging materials. Its core function is to precisely control the coating thickness and uniformity through a carefully controlled coating system (such as roller coating, blade coating, or spray coating). The equipment typically consists of an unwinding unit, coating head, drying system, tension control, and rewinding unit. Combined with an automated control system, it can efficiently complete continuous coating operations.

[0003] According to Chinese Patent No. CN222197558U, an adjustable coating thickness self-adhesive coating machine includes a connecting base. A drying box is fixedly connected to the front upper part of the connecting base. A lifting device is fixedly connected to the middle upper part of the connecting base. A bracket is fixedly connected to the rear upper part of the connecting base. The bracket has a "U"-shaped structure. Sliding grooves are opened at both the left and right ends of the bracket. A motor is fixedly connected to the lower right end of the bracket. A first connecting roller is fixedly connected to the output end of the motor. A coating roller is installed on the outer surface of the first connecting roller. An adjustment mechanism is fixedly connected to the upper end of the bracket.

[0004] In the above solution, the material is lifted by a lifting base, which still has the following disadvantages: Although the material is prevented from contacting the connecting seat after being lifted by the lifting base, dust in the external air may still contaminate the material during transportation. Utility Model Content

[0005] The purpose of this invention is to provide a thickness-adjustable mechanism for a coating machine to solve the problem that dust in the external environment may still contaminate the materials during transport.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a thickness-adjustable mechanism for a coating machine, including a connecting seat, a lifting base fixed on the top surface of the connecting seat, a plurality of mounting grooves opened on the top surface of the lifting base, a lifting roller rotatably arranged inside the mounting grooves, a shielding box provided on the top surface of the connecting seat, one side of the shielding box being rotatably connected to one side of the connecting seat via a hinge, inlets and outlets respectively opened on both sides of the shielding box, a feeding roller rotatably arranged inside the inlets and outlets, a handle fixed on one side of the shielding box, a drying chamber provided on the top surface of the connecting seat, and a bracket fixed on the top surface of the connecting seat.

[0007] Preferably, the support base is located inside the lower part of the shielding box, and the right-side inlet / outlet is higher than the left-side inlet / outlet.

[0008] Preferably, a motor is provided on one side of the bracket, and a connecting roller is rotatably arranged between the brackets. The output shaft of the motor passes through the bracket and is fixed to one end of the connecting roller.

[0009] Preferably, a sliding frame is slidably arranged inside the bracket, and a pressing roller is rotatably arranged inside the sliding frame. An electric push rod is provided on the top surface of the bracket, and a sleeve hole is opened on the top surface of the bracket. The telescopic rod of the electric push rod passes through the sleeve hole and is fixed to the top surface of the sliding frame.

[0010] Preferably, the top surface of the sliding frame has two sliding rods fixed, and the top surface of the bracket has two sliding holes, with the sliding rods slidably inserted into the sliding holes.

[0011] Preferably, the bracket has limit openings on both sides, and the limit openings are slidably disposed with the sliding frame.

[0012] Compared with existing technologies, the thickness-adjustable mechanism of a coating machine that adopts the above-mentioned technical solution has the following advantages:

[0013] 1. By supporting the hanging fabric with the support base, the hanging fabric is prevented from contacting the top surface of the connecting seat and getting dusty. In addition, when the fabric moves between the drying box and the support, it is inside the shield box to minimize contact with the external environment. This prevents dust in the air from adhering to the coated fabric and avoids contamination of the fabric during transportation.

[0014] 2. When the electric push rod is working, it will use the extended telescopic rod to push the sliding frame up and down, so that the squeezing roller inside the sliding frame moves up and down to adjust the height. Since the sliding frame slides up and down inside the limit port, and drives the sliding rod to slide up and down synchronously inside the sliding hole, the stability of the squeezing roller during movement can be increased, and the squeezing roller can be prevented from tilting and mismatched with the position of the connecting roller.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, a thickness-adjustable mechanism for a coating machine includes a connecting seat 1, a lifting base 2 fixed on the top surface of the connecting seat 1, a plurality of mounting grooves 3 on the top surface of the lifting base 2, a lifting roller 4 rotatably disposed inside the mounting grooves 3, a shielding box 5 disposed on the top surface of the connecting seat 1, one side of the shielding box 5 being rotatably disposed with one side of the connecting seat 1 via a hinge, inlets and outlets 6 respectively on both sides of the shielding box 5, a feeding roller 7 rotatably disposed inside the inlets and outlets 6, a handle 8 fixed on one side of the shielding box 5, a drying chamber 9 disposed on the top surface of the connecting seat 1, a bracket 10 fixed on the top surface of the connecting seat 1, the lifting base 2 being located inside and below the shielding box 5, and the right inlet and outlet 6 being higher than the left inlet and outlet 6.

[0022] In use, when the fabric slides between the drying box 9 and the bracket 10 above the connecting seat 1, the lowest point of the fabric will be supported upward by the lifting base 2. Multiple lifting rollers 4 on the top surface of the lifting base 2 are arranged in order from high to low, which can adaptively lift the fabric. When the fabric moves above the lifting base 2, it will pass through the inlet and outlet 6 on both sides of the shield box 5.

[0023] The hanging fabric is supported by the support base 2 to prevent it from contacting the top surface of the connecting seat 1 and getting dusty. In addition, when the fabric moves between the drying box 9 and the bracket 10, it is inside the shield box 5 to minimize contact with the external environment. This prevents dust in the air from adhering to the coated fabric and avoids contamination of the fabric during transportation.

[0024] like Figure 2 and Figure 4As shown, a motor 11 is provided on one side of the bracket 10, and a connecting roller 12 is rotatably arranged between the brackets 10. The output shaft of the motor 11 passes through the bracket 10 and is fixed to one end of the connecting roller 12. A sliding frame 13 is slidably arranged inside the bracket 10, and a pressing roller 14 is rotatably arranged inside the sliding frame 13. An electric push rod 15 is provided on the top surface of the bracket 10. A sleeve hole 16 is opened on the top surface of the bracket 10. The telescopic rod of the electric push rod 15 passes through the sleeve hole 16 and is fixed to the top surface of the sliding frame 13. Two sliding rods 18 are fixed on the top surface of the sliding frame 13. Two sliding holes 19 are opened on the top surface of the bracket 10. The sliding rods 18 are slidably inserted into the sliding holes 19. Limiting ports 17 are opened on both sides of the bracket 10, and the limiting ports 17 are slidably arranged with the sliding frame 13.

[0025] During use, the electric push rod 15 will use the extended telescopic rod to push the sliding frame 13 up and down, so that the squeezing roller 14 inside the sliding frame 13 can move up and down to adjust the height. Since the sliding frame 13 will slide up and down inside the limiting port 17, and drive the sliding rod 18 to slide up and down synchronously inside the sliding hole 19, the stability of the squeezing roller 14 during movement can be increased, and the squeezing roller 14 can be prevented from tilting and mismatching with the position of the connecting roller 12.
