[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 8 shown, the present invention provides an efficient eight-color printing device, including; A box body 1, the box body 1 is rectangularly arranged and a door body is arranged on the front, and a partition board 101 is fixedly installed inside. A mounting rack 102, fixedly installed on the top of the box body 1; A printing press 103, fixedly installed on the top of the mounting rack 102 and penetrating through the mounting rack 102, for printing materials. A positioning mechanism is arranged inside the box body 1 for positioning materials to prevent deviation during printing and reduce the quality of printed products. The positioning mechanism includes a driving component and a positioning component. The driving component is fixedly installed on the top of the partition board 101 to provide power for the positioning component. The positioning component includes a first clamping group and a second clamping group, which respectively position and clamp the printing materials in two directions of the X-axis and Z-axis to reduce printing errors. The driving component includes a motor 2 fixedly installed at the center of the top of the partition board 101. A gear 201 is fixedly sleeved on the output shaft of the motor 2. Two first sliding grooves 11, two second sliding grooves 12 and a positioning groove 13 are opened on the top of the box body 1. The first sliding grooves 11 are located at the wide sides of the top of the box body 1, the two second sliding grooves 12 are located at the long sides of the box body 1. Both the two first sliding grooves 11 and the second sliding grooves 12 penetrate through the box body 1. The positioning groove 13 is located at the center of the top of the box body 1 with a shallow groove depth and does not penetrate the box body 1, and the positioning groove 13 is designed in a cross shape. By setting the positioning groove 13, preliminary positioning can be carried out when the printing materials are clamped. By setting the first sliding grooves 11 and the second sliding grooves 12, a moving space is reserved for the positioning component.

[0021] The first clamping group has two sets, including a fixed block 1011 fixedly installed on the top of the box body 1. A first positioning block 4 is slidably installed on the top of the fixed block 1011. The first positioning block 4 is designed in an L shape and its top penetrates through and is slidably connected to the first sliding groove 11. A rack 401 is fixedly installed on the inner wall of the bottom side of the first positioning block 4. The rack 401 meshes with the gear 201. Two slide bars 3 are fixedly installed on the inner wall of the box body 1. The two slide bars 3 respectively penetrate through the corresponding rack 401 and are slidably connected to the corresponding rack 401, so as to limit the path of the moving rack 401 and make the rack 401 keep meshing with the gear 201.

[0022] Adopting the above scheme: The positioning assembly includes the first clamping group and the second clamping group, which can accurately position the printing material, avoiding printing errors caused by material movement or deviation during the printing process. The positioning assembly can automatically adjust according to the orientation of the material to ensure that each printing can achieve an ideal effect; By providing the first sliding groove 11 and the second sliding groove 12, the positioning assembly provides a flexible movement space, enabling the first clamping group and the second clamping group to work stably in different orientations, thus achieving high-precision printing. The driving assembly is powered by a motor 2 fixedly installed on the top of the partition plate 101. The motor 2 is connected to the gear 201 through an output shaft. The gear 201 meshes with the rack 401. This design makes the power transmission of the driving assembly more accurate and efficient, ensuring that the first positioning block 4 can accurately adjust its position according to the movement of the motor 2, thereby guaranteeing the stability and precision of the positioning system. By providing two first sliding grooves 11 and two second sliding grooves 12, the entire positioning assembly obtains more movement space and adjustment flexibility; The first sliding groove 11 and the second sliding groove 12 can provide a smooth sliding track for the first positioning block 4, enabling the positioning block to move smoothly in the groove and always maintain the meshing relationship with the rack 401; It improves the positioning accuracy, reduces the possibility of material deviation, and thus reduces printing errors caused by inaccurate positioning; The positioning groove 13 is designed in a cross shape, which not only provides a preliminary positioning function but also lays a foundation for subsequent fine positioning. The first clamping group can accurately clamp and position the wide side of the printing material through the cooperation of the fixed block 1011 and the first positioning block 4, ensuring that the material will not deviate during the printing process; At the same time, the second clamping group clamps the long side of the material, further improving the positioning accuracy and stability; This double-clamping design can not only ensure the stability of the printing material in multiple directions but also accurately place the material in the correct position during multi-color printing, avoiding color overlap or misalignment caused by inaccurate positioning. This efficient eight-color printing device can greatly reduce printing errors caused by material offset or misalignment through a precise positioning and clamping system; the positioning mechanism makes the operation more convenient and improves the working efficiency of the production line at the same time; in multi-color printing, it can ensure the accurate alignment of each layer of color, thus reducing the time of manual intervention and debugging and improving the production efficiency.

[0023] As Figures 3 to 5 shown, there are two sets of clamping groups II, including mounting blocks 5 fixedly installed on the inner wall of the top of the box body 1. Slide rails 501 are fixedly installed on the front and back of the mounting block 5 respectively. Slide blocks 5011 are slidably installed on the outer walls of the two slide rails 501 respectively. Positioning blocks II 502 are fixedly installed on the tops of the corresponding two slide blocks 5011 respectively. The two positioning blocks II 502 respectively penetrate through the corresponding sliding grooves II 12 and are slidably connected with the corresponding sliding grooves II 12. Two long connecting rods 6 are hingedly installed at the bottoms of the two positioning blocks I 4 respectively. The corresponding two long connecting rods 6 are respectively hinged with the corresponding two slide blocks 5011.

[0024] Adopting the above scheme: the installation of the slide rail 501 enables the slide block 5011 to slide smoothly within the fixed track, ensuring that the positioning block II 502 is accurately positioned along the predetermined track, avoiding errors caused by component loosening or offset during the operation. This precise guidance avoids the instability of the mechanical position, thus greatly improving the positioning accuracy of the system. The cooperation of the slide rail 501 and the slide block 5011 makes the positioning block II 502 more stable during the whole operation process, reducing the unsmooth sliding caused by friction and uneven pressure, ensuring the long-term stable operation of the equipment. The design of the sliding groove II 12 enables the positioning block II 502 to be flexibly adjusted during the movement, ensuring that the positioning block can be accurately adjusted to the appropriate position for clamping under different material and process conditions. This flexibility is particularly important in a diversified production line and can adapt to materials of different specifications and thicknesses for efficient operation. The sliding design of the sliding groove II 12 ensures that the contact area between the positioning block II 502 and the inner wall of the groove is small, thus reducing the frictional force and the possible damage to the material surface during the operation. Especially for precision or fragile materials, it can better protect the materials from being scratched or damaged.

[0025] As Figures 7 to 8 shown, pre-positioning components are respectively arranged on the sides of the two positioning blocks II 502 on the same side that are close to each other. The pre-positioning components include damping rods 7 fixedly installed on the sides of the two slide rails 501 that are close to each other. Two moving blocks 701 are slidably installed on the outer walls of the damping rods 7. Short connecting rods 7011 are hingedly installed on one side of the two moving blocks 701 respectively. Two short connecting rods 7011 are both hingedly installed with rectangular blocks 7012. The two moving blocks 701 and the adjacent positioning blocks II 502 are elastically connected by springs 702 respectively.

[0026] Adopting the above solution: The damping rod 7 in the positioning component is fixedly installed on one side where two slide rails 501 are close to each other, while the moving block 701 is slidably installed on the outer wall of the damping rod 7. By making the moving block 701 slide along a certain path under the guidance of the damping rod 7, the precise alignment of the second positioning block 502 is ensured. The moving block 701 can move on a predetermined track under the restriction and guidance of the damping rod 7, thus avoiding deviation or misalignment during the positioning process. The damping rod 7 has the function of absorbing vibration and buffering, avoiding mechanical deviation caused by vibration or external interference. Especially during high-speed positioning, vibration may cause inaccurate material position. Using the damping rod 7 effectively improves the stability of positioning. The short connecting rods 7011 are respectively connected to the two moving blocks 701, and the other end of each short connecting rod 7011 is hinged to a rectangular block 7012. When the two moving blocks 701 slide along the damping rod 7, the short connecting rods 7011 will drive the rectangular block 7012 to move synchronously. Since there is an elastic connection between the rectangular block 7012 and the second positioning block 502, the movement of the short connecting rods 7011 can effectively make fine adjustments to the material. The short connecting rods 7011 and the rectangular block 7012 work together to achieve synchronous adjustment. During the positioning process, the two rectangular blocks 7012 evenly apply pressure to the material to ensure that the long side of the material is evenly and firmly clamped. The rectangular block 7012 transmits the position change through the short connecting rod 7011 in linkage with the moving block 701, avoiding material position deviation caused by mechanical errors. This linkage mechanism ensures that the material will not be misaligned due to uneven pressure distribution or looseness between components. The spring 702 can adjust the pressure applied to the material according to the thickness of different materials, avoiding material deformation or inaccurate positioning caused by too large or too small pressure. The flexible design of the spring 702 ensures that the second positioning block 502 can adapt to the different needs of various types of materials and maintain a good clamping force.

[0027] The working principle and usage process of the present invention: First, place the material to be printed roughly on the top of the box body 1 according to the center of the positioning groove 13. Then start the motor 2. The output shaft of the motor 2 rotates to drive the gear 201 to rotate. Through the meshing of the gear 201 with the two racks 401, the two racks 401 are driven to perform a linear motion of approaching or separating from each other. The two racks 401 drive the corresponding first positioning blocks 4 to move together. During the movement of the two first positioning blocks 4, the two long connecting rods 6 at the bottom jointly drive the slider 5011 at the other end to slide on the slide rail 501. The two racks 401 can correct and clamp the wide side of the material to be printed. The four sliders 5011 drive the two second positioning blocks 502 to correct and clamp the long side of the material to be printed. During the process of the two second positioning blocks 502 approaching each other, the two rectangular blocks 7012 first come into contact with the material to be printed, and through the slow movement of the second positioning blocks 502, the two rectangular blocks 7012 push the two moving blocks 701 in the opposite direction through the short connecting rods 7011 at both ends, so that the two moving blocks 701 respectively move along the axis of the damping rod 7 and slowly approach the second positioning blocks 502. The movement of the moving blocks 701 squeezes the springs 702 located between the moving blocks 701 and the second positioning blocks 502, ensuring that the material will not shift during the pre-positioning process. At the same time, the existence of the springs 702 further enhances the stability during the positioning process, avoiding unnecessary movement or deformation of the material during the clamping process. When the four sides of the material to be printed are positioned and clamped, then start the printing machine 103 on the mounting frame 102 to print the material.
