Description

Technical Field

[0001] This utility model relates to the field of coated paper technology, and specifically to a printing device for coated paper processing. Background Technology

[0002] Laminated paper is a composite material made by coating plastic particles onto the surface of paper using a casting machine. Its main characteristics are oil resistance (relatively), water resistance (relatively), and heat-sealing capability. Different uses utilize different properties: when used for packaging hamburgers, its oil resistance is utilized; McDonald's products can withstand 80-degree edible vegetable oil for 10 minutes without leaking. When used for coated paper packaging, its water resistance is utilized. When used in automatic packaging machines, its heat-sealing capability is utilized. During the processing of laminated paper, different patterns need to be printed on its surface depending on its intended use, thus requiring a printing device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

An arc-shaped groove is provided above the square fixing frame, and a T-shaped sliding groove is provided above the square block.

[0008] A further improvement of the present invention is that the transmission roller includes two transmission rollers, and an arc-shaped fixing frame is rotatably connected to the outer wall of the two transmission rollers that are far apart from each other. The lower part of the arc-shaped fixing frame is fixedly connected to the upper part of the square plate.

[0009] A further improvement of the present invention is that the printing roller includes a circular rotating roller, a printing cylinder is fixedly connected to the outer wall of the circular rotating roller, a cross-shaped block is fixedly connected to the left side of the circular rotating roller, and the outer wall of the circular rotating roller is slidably connected to the inner wall of the arc-shaped groove.

[0010] A further improvement of this utility model is that: the rotating mechanism includes a cylinder, both sides of which are provided with bidirectional threaded grooves, and T-shaped sliding blocks are threadedly connected to the outer walls of both sides of the bidirectional threaded grooves. A motor is fixedly connected to the left side of the cylinder, and an arc-shaped fixing frame II is fixedly connected above the T-shaped sliding block. A circular block is fixedly connected above the side of the arc-shaped fixing frame II facing the circular rotating roller on the right side. A circular block is rotatably connected to the inner wall of the arc-shaped fixing frame II on the left side. The left side of the circular block passes through the left side of the arc-shaped fixing frame II to the outside. A motor I is fixedly connected to the left side of the circular block. The right side of the motor I is fixedly connected to the left side of the arc-shaped fixing frame II on the left side. A cross groove is provided on the right side of the circular block on the left side. The inner wall of the left side of the circular block is movably connected to the outer wall of the right side of the circular roller. The inner wall of the cross groove is inserted into the outer wall of the cross-shaped block. The T-shaped sliding block is slidably connected to the inner wall of the T-shaped sliding groove. The outer wall of the cylinder is rotatably connected to the inner wall of the square plate. The outer wall of the motor is fixedly connected to the inner wall of the square block.

[0011] A further improvement of this utility model's technical solution is as follows: the lifting mechanism includes two square fixed plates. A square fixed seat is fixedly connected to the lower square fixed plate, and a square printing table is fixedly connected to the upper square fixed plate. A square sliding hole is opened on the inner left side of the square fixed plate, extending from the front and rear sides to the outside. A square sliding rod is slidably connected to the inner wall of the square sliding hole. Two cylinders are fixedly connected to the front and rear sides of the square sliding rod. A threaded rod is threadedly connected to the inner wall of the lower square fixed plate. A motor is fixedly connected to the left side of the threaded rod, passing through the left side of the square fixed plate. The lower part of the motor is fixedly connected to the upper part of the square fixed seat. The outer wall of the threaded rod is rotatably connected to the inner wall of the square fixed plate.

Square support rods are rotatably connected to the outer walls of the left and right sides of the cylindrical fixed rod and the outer walls of the two cylinders. Two adjacent square support rods are rotatably connected at the middle in an X-shape. The lower part of the square fixed seat is fixedly connected to the upper part of the square plate.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. The cylinder is driven to rotate by the motor output, causing the two-way threaded grooves on both sides and the T-shaped sliding blocks on both sides to rotate. This causes the T-shaped sliding blocks on both sides to move the two arc-shaped fixed frames in opposite directions, allowing the cross groove to slide and disengage from the cross-shaped block and the right circular block to slide and disengage from the right side of the circular rotating roller. Then, grasp the circular rotating roller or printing cylinder and move it upwards, allowing the circular rotating roller to slide with the arc groove and be removed for disassembly. During installation, simply place the circular rotating roller on the arc groove, and then, through the above operations, insert the cross groove into the cross-shaped block and the circular block into the printing cylinder. The left circular block is then driven to rotate by the motor output, causing the cross groove to drive the circular rotating roller and the printing cylinder to rotate for printing. Compared with the traditional complex installation and disassembly methods, the operation is simpler and faster, effectively shortening the printing roller replacement time and improving production efficiency. It is especially suitable for scenarios that require frequent replacement of printing rollers to meet different printing needs.

[0014] 2. The output end of motor two drives the threaded rod to rotate, causing the thread to slide the lower square sliding rod. This causes cylinder two and the square support rod to rotate, which in turn rotates with the cylindrical fixed rod, raising the upper square fixed plate and thus raising the square printing table. During the printing process, the materials to be printed vary in thickness, such as paper and plastic film. Different materials require different distances between the printing roller and the printing table. With the addition of a lifting mechanism, the distance can be flexibly adjusted according to the material thickness, ensuring good contact between the printing roller and the material surface, uniform ink transfer, and guaranteeing printing quality. Appropriate printing pressure ensures that the ink adheres clearly and firmly to the material surface. Too much or too little pressure will lead to printing defects. By adjusting the distance between the roller and the printing roller through the lifting mechanism, the printing pressure can be precisely controlled to meet the pressure requirements of different printing processes and materials, reducing printing defects.

Detailed Implementation

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1-2 As shown, this utility model provides a printing device for processing coated paper, including a worktable 1, transmission rollers 2 fixedly connected to the front and rear sides of the worktable 1, a lifting mechanism 5 fixedly connected to the middle of the upper part of the worktable 1, printing rollers 3 slidably connected to the left and right sides of the middle of the upper part of the worktable 1, and a rotating mechanism 4 provided on the inner walls of the left and right sides of the worktable 1.

[0023] The rotating mechanism 4 allows for easy disassembly of the printing roller 3. Compared to the traditional complex installation and disassembly methods, the operation is simpler and faster, which can effectively shorten the replacement time of the printing roller and improve production efficiency. It is especially suitable for scenarios that require frequent replacement of printing rollers to meet different printing needs. The lifting mechanism 5 can adjust the distance between the printing roller and the printing roller 3. It can be flexibly adjusted according to the material thickness to ensure good contact between the printing roller and the material surface, so that the ink is transferred evenly and the printing quality is guaranteed.

[0024] like Figure 3 The present invention provides a technical solution: the workbench 1 includes a square plate 11, square blocks 12 are fixedly connected to the left and right sides of the square plate 11, and square fixing frames 13 are fixedly connected to the left and right sides of the upper center of the square plate 11. A circular arc groove 14 is opened on the upper part of the square fixing frame 13, and a T-shaped sliding groove 15 is opened on the upper part of the square block 12. The transmission roller 2 includes two transmission rollers 22, and a circular arc fixing frame 21 is rotatably connected to the outer wall of the two transmission rollers 22 that are far apart. The lower part of the circular arc fixing frame 21 is fixedly connected to the upper part of the square plate 11.

[0025] like Figure 4The present invention provides a technical solution: the printing roller 3 includes a circular rotating roller 31, a printing cylinder 32 is fixedly connected to the outer wall of the circular rotating roller 31, a cross-shaped block 33 is fixedly connected to the left side of the circular rotating roller 31, the outer wall of the circular rotating roller 31 is slidably connected to the inner wall of the arc-shaped groove 14, the rotating mechanism 4 includes a cylinder 48, bidirectional threaded grooves 46 are provided on both the left and right sides of the cylinder 48, T-shaped sliding blocks 45 are threadedly connected to the outer walls of both bidirectional threaded grooves 46, a motor 47 is fixedly connected to the left side of the cylinder 48, an arc-shaped fixing frame 2 41 is fixedly connected above the T-shaped sliding block 45, and a circular block 4 is fixedly connected above the side of the arc-shaped fixing frame 2 41 facing the circular rotating roller 31 on the right side. 2. A circular block 42 is rotatably connected to the inner wall of the left arc-shaped fixing frame 2 41. The left side of the circular block 42 passes through the left side of the left arc-shaped fixing frame 2 41 to the outside. A motor 1 44 is fixedly connected to the left side of the circular block 42. The right side of the motor 1 44 is fixedly connected to the left side of the left arc-shaped fixing frame 2 41. A cross groove 43 is opened on the right side of the circular block 42. The left inner wall of the circular block 42 is movably connected to the right outer wall of the circular rotating roller 31. The inner wall of the cross groove 43 is inserted into the outer wall of the cross-shaped block 33. The T-shaped sliding block 45 is slidably connected to the inner wall of the T-shaped sliding groove 15. The outer wall of the cylinder 48 is rotatably connected to the inner wall of the square plate 11. The outer wall of the motor 47 is fixedly connected to the inner wall of the square block 12.

[0026] After passing under the rear drive roller 22, the coated paper passes over the lifting mechanism 5 and then under the front drive roller 22. The printing roller 3 prints on the coated paper above the lifting mechanism 5.

[0027] The printing roller 3 and the rotating mechanism 4 facilitate the disassembly of the printing roller. During use, the output of the motor 47 drives the cylinder 48 to rotate, causing the two-way threaded grooves 46 and the two T-shaped sliding blocks 45 to rotate. This causes the T-shaped sliding blocks 45 to move the two arc-shaped fixing frames 41 in opposite directions, resulting in the cross groove 43 sliding against the cross-shaped block 33 and the right circular block 42 sliding against the right side of the circular rotating roller 31, disengaging them. Then, grasp the circular rotating roller 31 or the printing cylinder 32 and move it upwards, causing the circular rotating roller 31 to slide against the arc-shaped groove 14, allowing it to be removed for disassembly. During installation, simply place the circular rotating roller 31 on the arc-shaped groove 14, and then, through the above operations, connect the cross groove 43 to the cross block 33 and the circular block 42 to the printing cylinder 32. Then, drive the left circular block 42 to rotate through the output end of the motor 44, thereby causing the cross groove 43 to drive the circular rotating roller 31 and the printing cylinder 32 to rotate and print. Compared with the traditional complicated installation and disassembly methods, the operation is simpler and faster, which can effectively shorten the printing roller replacement time and improve production efficiency. It is especially suitable for scenarios that require frequent replacement of printing rollers to meet different printing needs.

[0028] like Figure 5The present invention provides a technical solution: the lifting mechanism 5 includes two square fixing plates 52. A square fixing seat 51 is fixedly connected to the lower square fixing plate 52, and a square printing table 511 is fixedly connected to the upper square fixing plate 52. A square sliding hole 53 is opened on the inner wall of the left side of the square fixing plate 52, extending from the front and rear sides to the outside. A square sliding rod 54 is slidably connected to the inner wall of the square sliding hole 53. A cylinder 55 is fixedly connected to the front and rear sides of the square sliding rod 54. A threaded rod 58 is threadedly connected to the inner wall of the lower square fixing plate 52. The threaded rod 58 passes through the square fixing plate 52 on the left side. A motor 59 is fixedly connected to the left side of the fixed plate 52. The lower part of the motor 59 is fixedly connected to the upper part of the square fixed base 51. The outer wall of the threaded rod 58 is rotatably connected to the inner wall of the square fixed plate 52. A cylindrical fixed rod 56 is fixedly connected to the inner wall of the right side of the square fixed plate 52. The cylindrical fixed rod 56 passes through the front and rear sides of the square fixed plate 52 to the outside. The outer walls of the left and right sides of the cylindrical fixed rod 56 are rotatably connected to the outer walls of the two cylindrical rods 55 on both sides. Two adjacent square support rods 57 are rotatably connected in the middle of an X-shape. The lower part of the square fixed base 51 is fixedly connected to the upper part of the square plate 11.

[0029] The lifting mechanism 5 can be raised and lowered. During use, the output end of motor 2 59 drives the threaded rod 58 to rotate, which in turn drives the lower square sliding rod 54 to slide. This causes the cylinder 2 55 and the square support rod 57 to rotate, and then the square support rod 57 and the cylindrical fixed rod 56 to rotate, causing the upper square fixed plate 52 to rise. This, in turn, causes the square printing table 511 to rise. During the printing process, the materials to be printed vary in thickness, such as paper and plastic film. Different materials have different requirements for the distance between the printing roller and the printing table. With the addition of the lifting mechanism 5, the distance can be flexibly adjusted according to the material thickness to ensure good contact between the printing roller and the material surface, so that the ink is transferred evenly and the printing quality is guaranteed. Appropriate printing pressure can make the ink adhere clearly and firmly to the material surface. Too much or too little pressure will lead to printing defects. By adjusting the distance between the lifting mechanism 5 and the printing roller, the printing pressure can be precisely controlled to meet the pressure requirements of different printing processes and materials, and reduce printing defects.

[0030] The working principle of the printing device used for coating paper processing is explained in detail below: After the coating paper passes under the rear drive roller 22, it passes over the lifting mechanism 5, and then passes under the front drive roller 22. The printing roller 3 prints on the coating paper above the lifting mechanism 5.

[0031] The printing roller 3 and the rotating mechanism 4 facilitate the disassembly of the printing roller. During use, the output of the motor 47 drives the cylinder 48 to rotate, causing the two-way threaded grooves 46 and the two T-shaped sliding blocks 45 to rotate. This causes the T-shaped sliding blocks 45 to move the two arc-shaped fixing frames 41 in opposite directions, resulting in the cross groove 43 sliding against the cross-shaped block 33 and the right circular block 42 sliding against the right side of the circular rotating roller 31, disengaging them. Then, grasp the circular rotating roller 31 or the printing cylinder 32 and move it upwards, causing the circular rotating roller 31 to slide against the arc-shaped groove 14, allowing it to be removed for disassembly. During installation, simply place the circular rotating roller 31 on the arc-shaped groove 14, and then, through the above operations, connect the cross groove 43 to the cross block 33 and the circular block 42 to the printing cylinder 32. Then, drive the left circular block 42 to rotate through the output end of the motor 44, thereby causing the cross groove 43 to drive the circular rotating roller 31 and the printing cylinder 32 to rotate and print. Compared with the traditional complicated installation and disassembly methods, the operation is simpler and faster, which can effectively shorten the printing roller replacement time and improve production efficiency. It is especially suitable for scenarios that require frequent replacement of printing rollers to meet different printing needs.

[0032] The lifting mechanism 5 can be raised and lowered. During use, the output end of motor 2 59 drives the threaded rod 58 to rotate, which in turn drives the lower square sliding rod 54 to slide. This causes the cylinder 2 55 and the square support rod 57 to rotate, and then the square support rod 57 and the cylindrical fixed rod 56 to rotate, causing the upper square fixed plate 52 to rise. This, in turn, causes the square printing table 511 to rise. During the printing process, the materials to be printed vary in thickness, such as paper and plastic film. Different materials have different requirements for the distance between the printing roller and the printing table. With the addition of the lifting mechanism 5, the distance can be flexibly adjusted according to the material thickness to ensure good contact between the printing roller and the material surface, so that the ink is transferred evenly and the printing quality is guaranteed. Appropriate printing pressure can make the ink adhere clearly and firmly to the material surface. Too much or too little pressure will lead to printing defects. By adjusting the distance between the lifting mechanism 5 and the printing roller, the printing pressure can be precisely controlled to meet the pressure requirements of different printing processes and materials, and reduce printing defects.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
