Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly plastic-free paper cup technology, and in particular to an environmentally friendly plastic-free paper cup coating machine. Background Technology

[0002] Environmentally friendly plastic-free paper cups are a new type of environmentally friendly container that uses biodegradable materials to replace plastic coatings. Its core feature is that the entire process is environmentally friendly: the base paper of the cup body is made from FSC-certified sustainable forest pulp, and the coating uses plant-based materials (such as polylactic acid PLA, starch-based coating, natural beeswax, etc.). It can achieve waterproof and oil-proof functions without plastic. The production process avoids the use of organic solvents, reducing VOCs emissions. After disposal, it can be degraded into water and carbon dioxide through composting, solving the recycling problem of "difficulty in separating paper and plastic" in traditional paper cups. During the processing of paper cups, coating machines are often used to coat the paper cups.

[0003] In daily work, it has been found that existing environmentally friendly plastic-free paper cup coating machines coat paper cups with coating rollers. However, during the coating process, the paper cups often fail to maintain a stable state when in contact with the coating rollers. This instability directly leads to insufficient contact force between the paper cups and the coating rollers. Due to insufficient contact force, the coating effect is affected, making it difficult to achieve the expected uniform effect, which in turn affects the overall quality of the paper cups. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that paper cups are difficult to contact stably with the coating roller, resulting in insufficient contact force and affecting the coating effect, and to propose an environmentally friendly plastic-free paper cup coating machine.

The bidirectional screw is threadedly connected to the inner walls of the two limiting rings respectively. Through the above components, the bidirectional screw can be rotated, and the bidirectional screw can control the movement of the two limiting rings on the pressure roller, thereby realizing the limiting of the paper cup paper.

[0009] Preferably, the surface of the raw material box is provided with a stirring assembly, which includes two stirring rods rotatably connected to the inner wall of the raw material box. A transmission part is provided between the stirring rods and the coating roller. Through the above-mentioned components, when the coating roller rotates, the two stirring rods can be driven to rotate through the transmission part, thereby stirring the raw materials in the raw material box and reducing the phenomenon of sedimentation.

[0010] Preferably, the transmission unit includes a second belt, which is mounted on the coating roller and a set of stirring rods. A third belt is installed between the two stirring rods. Through the above components, when the coating roller rotates, the second belt can drive the set of stirring rods to rotate, and at the same time, the stirring rods can drive the other set of stirring rods to rotate through the third belt, thereby realizing the stirring operation.

[0011] Preferably, the two stirring rods are respectively located on both sides of the coating roller.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting an auxiliary device, the drive unit controls the rotation of two sets of transmission rods. The transmission rods, in conjunction with the worm gear, drive the rod body, control arm, and pressure roller to rotate, so that the pressure rollers on both sides can press down on the paper cup paper, ensuring that the paper cup paper is in stable contact with the coating roller, improving the uniformity and consistency of coating, and enhancing the overall practicality.

[0023] Specifically, the auxiliary device 6 includes multiple rods 61, which are rotatably connected to the two side surfaces of the raw material box 3. Control arms 62 are fixedly connected to the surface of the rods 61, and pressure rollers 63 are rotatably connected to the inner walls of the two control arms 62. The pressure rollers 63 are provided with limiting parts 64 that can limit the paper cup paper. Worm gears 65 are fixedly connected to the surface of the rods 61. Transmission rods 66 are rotatably connected to the inner walls of both sides of the raw material box 3. The transmission rods 66 are meshed with the worm gears 65. The raw material box 3 is provided with a drive unit 67 that can drive the transmission rods 66 to rotate. The drive unit 67 includes a control motor 672 mounted on the surface of the raw material box 3. The output end of the control motor 672 is fixedly connected to the surface of a set of transmission rods 66. A belt 671 is installed between the two transmission rods 66. The transmission rods 66 include shafts 661, and two worm gears 662 are fixedly connected to the surface of the shafts 661.

[0024] In this implementation scheme: when the control motor 672 is turned on, the control motor 672 can drive a set of transmission rods 66 to rotate. The transmission rods 66 drive another set of transmission rods 66 to rotate synchronously through belt 671. The transmission rods 66 control the worm gear 65, the control arm 62 and the pressure roller 63 to rotate. The pressure roller 63 presses down on the paper cup paper, so that the paper cup paper can stably contact the coating roller 4, thereby improving the coating effect.

[0025] Specifically, the limiting part 64 includes two limiting rings 641 sleeved on the pressure roller 63, a hollow seat 643 fixedly connected to the surface of the control arm 62, and a bidirectional screw 642 rotatably connected to the inner wall of the hollow seat 643. The bidirectional screw 642 is threadedly connected to the inner wall of the two limiting rings 641 respectively.

[0026] In this implementation scheme: the bidirectional screw 642 can be rotated, and the bidirectional screw 642 can control the two limiting rings 641 to move on the pressure roller 63, thereby limiting the paper cup paper.

[0027] Specifically, the surface of the raw material box 3 is provided with a stirring assembly 7. The stirring assembly 7 includes two stirring rods 71 ​​that are rotatably connected to the inner wall of the raw material box 3. A transmission part is provided between the stirring rods 71 ​​and the coating roller body 4. The transmission part includes a second belt 72, which is installed on the coating roller body 4 and a set of stirring rods 71. A third belt 73 is installed between the two stirring rods 71. The two stirring rods 71 ​​are respectively located on both sides of the coating roller body 4.

[0028] In this implementation scheme: when the coating roller 4 rotates, the second belt 72 can drive a set of stirring rods 71 ​​to rotate. At the same time, the stirring rods 71 ​​can drive another set of stirring rods 71 ​​to rotate through the third belt 73, thereby realizing the stirring of the raw materials in the raw material box 3 and reducing the phenomenon of sedimentation.

[0029] Working principle: During operation, the paper cup paper passes over the coating roller 4. Then, the control motor 672 is turned on, which drives a set of transmission rods 66 to rotate. The transmission rods 66 drive another set of transmission rods 66 to rotate synchronously via belt 671. The worm gear 662 in the transmission rods 66 controls the worm wheel 65 and the rod body 61 to rotate, thereby driving the control arm 62 and the pressure roller 63 to rotate. The pressure rollers 63 on both sides of the raw material box 3 press down on the paper cup paper, so that the paper cup paper can stably contact the coating roller 4. Then, the drive motor 5 drives the coating roller 4 to rotate. The coating roller 4 contacts the raw material in the raw material box 3 and coats the paper cup paper, improving the coating effect. When the coating roller 4 rotates, belt 72 drives a set of stirring rods 71 ​​to rotate. At the same time, the stirring rods 71 ​​drive another set of stirring rods 71 ​​via belt 73, thereby agitating the raw material in the raw material box 3 and reducing sedimentation.
