Description

Technical Field

[0001] This utility model relates to the field of coated paper technology, specifically to a high-efficiency coated paper production coated paper coating device. Background Technology

[0002] Coated paper is a composite material in which plastic particles are melted and uniformly coated onto the surface of paper using a coating machine. It is oil-proof, waterproof, and heat-sealing. The coating machine, also known as an extrusion casting laminating machine, is a type of extrusion molding machinery. It has advantages such as high degree of automation, simple operation, high production speed, uniform coating thickness, high adhesion, flat winding, environmental protection and pollution-free, and saving labor and raw material costs. Most existing coating equipment processes single sheets on one side, and the coating is dried naturally or cooled naturally after coating. The cooling time is long, which occupies production resources and has low production efficiency.

[0003] According to Chinese Patent Publication No. CN216193663U, a high-efficiency coating device for producing coated paper is disclosed. This device includes a housing, a mirror coating assembly, and a cooling assembly. The housing has symmetrically arranged inlet and outlet ports on its two side walls, with the inlet port located below the outlet port. The mirror coating assembly and the cooling assembly are arranged side-by-side inside the housing, with the cooling assembly located below the mirror coating assembly. This utility model belongs to the technical field of coated paper processing equipment, specifically referring to a high-efficiency coating device for producing coated paper with short cooling time and high production efficiency.

[0004] The above-mentioned device still has some shortcomings in use: for example, coated paper has single-sided coating and double-sided coating, and the above-mentioned coating device can only perform coating operation on one side of the coated paper substrate at a time. When processing coated paper substrates that require double-sided coating, it is necessary to process the other side after processing one side, which is cumbersome. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency coating device for producing coated paper, so as to solve the shortcomings mentioned in the background art that still exist in use: such as coated paper having single-sided coating and double-sided coating, the above-mentioned coating device can only perform coating operation on one side of the coated paper substrate at a time, and when processing coated paper substrates that require double-sided coating, it is necessary to process the other side after processing one side, which is cumbersome.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency coated paper production coated paper device, including a base, a coated paper mechanism is provided on the inner side of the base, and a transmission mechanism is provided on the outer side of the coated paper mechanism;

[0007] The coating mechanism includes a support frame, on the inner side of which a conveying roller, a first support roller, a second support roller, and a take-up roller are rotatably connected. A cylinder is fixedly connected to the outside of the support frame, and a pressure frame is fixedly connected to the bottom of the cylinder. A pressure roller is rotatably connected to the inner side of the pressure frame. A paint extruder is mounted on the top of the support frame, and a paint pipe is mounted on one end of the paint extruder. A nozzle is fixedly connected to the bottom of the paint pipe.

[0008] Preferably, the support frame is fixedly connected to the top of the base, the take-up roller is disposed on the top of the conveying roller, and the first support roller is disposed on the top of the second support roller.

[0009] Preferably, the coating tube is configured as a forked tube, with one end of the coating tube passing through the support frame and extending to the top of the first support roller and the second support roller.

[0010] Preferably, multiple nozzles are provided, and the multiple nozzles are arranged in a linear array.

[0011] Preferably, the transmission mechanism includes multiple rotating shafts, each of which is fixedly connected to a synchronous pulley, and the synchronous pulleys are connected by a synchronous belt, with a motor installed at one end of one of the rotating shafts.

[0012] Preferably, the plurality of the rotating shafts are respectively installed inside the conveying roller and the winding roller, and one end of each of the plurality of rotating shafts passes through the support frame and extends to the outside of the support frame.

[0013] Preferably, a fixed base is installed at one end of the motor, and one end of the fixed base is fixedly connected to one end of the support frame.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, the coated paper substrate of this utility model is first laid flat on the surface of the conveyor roller, and one end is guided and attached to the first support roller for initial positioning. Then, the substrate passes through the pressure roller driven by the cylinder and pressed down by the pressure frame. The pressure can be adjusted to keep the substrate in a flat state. The flipping action of the pressure roller makes the back of the substrate face up. After being guided by the second support roller for a second time, it is connected to the winding roller to form a continuous conveying path. During this process, the coating extruder is started to inject molten coating into the bifurcated coating tube. The bifurcated tubes extend to the top areas of the first and second support rollers respectively. The plastic coating is precisely sprayed onto the original front and the flipped back of the substrate simultaneously through the linear array of nozzles. This achieves double-sided synchronous coating with a single material feed, effectively eliminating the secondary material feed operation of the traditional process and improving the coating efficiency.

[0016] Secondly, this utility model uses a motor to drive a rotating shaft to rotate, which in turn drives the external synchronous pulley to rotate, thereby enabling the external synchronous belt to drive the synchronous pulley at the other end of the synchronous belt to rotate, which in turn drives another rotating shaft to rotate, thus causing the conveyor roller and the take-up roller to rotate simultaneously, thereby avoiding the vibration and offset problem of traditional gear transmission.

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A high-efficiency coated paper production coating device includes a base 1, a coating mechanism 2 is arranged inside the base 1, and a transmission mechanism 3 is arranged outside the coating mechanism 2.

[0026] The coating mechanism 2 includes a support frame 21. A conveying roller 22, a first support roller 23, a second support roller 24 and a take-up roller 25 are rotatably connected to the inner side of the support frame 21. A cylinder 26 is fixedly connected to the outside of the support frame 21. A pressure frame 27 is fixedly connected to the bottom of the cylinder 26. A pressure roller 28 is rotatably connected to the inner side of the pressure frame 27. A paint extruder 29 is installed on the top of the support frame 21. A paint pipe 201 is installed at one end of the paint extruder 29. A nozzle 202 is fixedly connected to the bottom of the paint pipe 201.

[0027] The support frame 21 is fixedly connected to the top of the base 1, the winding roller 25 is disposed on the top of the conveying roller 22, and the first support roller 23 is disposed on the top of the second support roller 24.

[0028] The paint tube 201 is configured as a fork, with one end of the paint tube 201 passing through the support frame 21 and extending to the top of the first support roller 23 and the second support roller 24.

[0029] There are multiple nozzles 202, and the multiple nozzles 202 are arranged in a linear array.

[0030] Through the above technical solution, the coated paper substrate is first laid flat on the surface of the conveyor roller 22, and one end is guided and attached to the first support roller 23 for initial positioning. Then the substrate passes through the pressure roller 28 driven by the cylinder 26 and pressed down by the pressure frame 27. The pressure can be adjusted to keep the substrate in a flat state. The flipping action of the pressure roller 28 makes the back of the substrate face up. After being guided a second time by the second support roller 24, it is connected to the winding roller 25 to form a continuous conveying path. During this process, the coating extruder 29 is started to inject molten coating into the bifurcated coating tube 201. The bifurcated tubes extend to the top areas of the first support roller 23 and the second support roller 24 respectively. The plastic coating is precisely sprayed onto the original front and the flipped back of the substrate simultaneously through the linearly arrayed nozzles 202, realizing double-sided synchronous coating in a single pass, effectively eliminating the secondary pass operation of the traditional process and improving the coating efficiency.

[0034] One end of the motor 34 is equipped with a fixed base, and one end of the fixed base is fixedly connected to one end of the support frame 21.

[0035] Through the above technical solution, the motor 34 drives a rotating shaft 31 to rotate, which in turn drives the external synchronous pulley 32 to rotate, thereby driving the external synchronous belt 33 to rotate, which in turn drives the synchronous pulley 32 at the other end of the synchronous belt 33 to rotate, thereby driving another rotating shaft 31 to rotate, and thus causing the conveying roller 22 and the winding roller 25 to rotate simultaneously, thereby avoiding the vibration and offset problem of traditional gear transmission.
