A rotary printing mechanism

Abstract

This utility model discloses a rotary printing mechanism in the field of printing machinery, including a screen printing assembly, a substrate rotation assembly, and a linear module. The substrate rotation assembly includes a clamping module and a linear module. The linear module includes a linear guide rail, a linear slider, and a telescopic cylinder. The rotary cylinder is fixedly installed on the end face of the linear slider and moves with it. After the substrate completes the first side printing process, the telescopic cylinder drives the linear slider to move backward a certain distance, thereby moving the substrate away from the screen. Then, the rotary cylinder drives the clamping component to flip, thereby causing the substrate to flip. The telescopic cylinder drives the linear slider to move forward a certain distance, thereby moving the substrate below the screen for the second side printing. During the printing process, the servo motor drives the axial slider to slide along the length direction of the axial guide rail, thereby driving the squeegee and squeegee blade to scrape ink. The ink is transferred through the screen to the substrate, which can greatly improve the double-sided printing efficiency of the substrate.

Description

Technical Field

[0001] This utility model relates to the field of printing mechanism technology, specifically a rotary printing mechanism. Background Technology

[0002] Paper packaging has a wide range of applications, and various types of paper packaging are used in all aspects of human life and production. With the deepening application of paper packaging in the consumer field, consumer behavior has also put forward new requirements for the paper packaging industry, which originally did not pay much attention to product marketing and whose sales targets are downstream industries. The performance design and decoration design of paper packaging products have become the direction of product development in the industry. Various new equipment, new processes and new technologies have been developed to design paper packaging with strong folding and pressure resistance, good printing effect and a wide variety of packaging colors and patterns to meet consumer needs. Printing is a technology that uses processes such as plate making, inking and pressing to transfer ink to the surface of materials such as paper, textiles, plastics, and leather to reproduce the content of the original manuscript in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special inks.

[0003] Most existing paper printing facilities can only print on one side of the paper. When double-sided printing is required, it is mostly done manually by flipping the paper, which makes double-sided printing quite troublesome. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a rotary printing mechanism, which can effectively solve the technical problem that most existing paper product printing mechanisms can only complete single-sided printing of paper. When double-sided printing of paper is required, it mostly relies on manual flipping of the paper to complete the double-sided printing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rotary printing mechanism, including a worktable, a screen printing component on one side of the worktable, a substrate rotating component on the side of the worktable away from the screen printing component, and a linear module for driving the substrate rotating component to make linear displacement motion.

[0006] The substrate rotation assembly includes a set of symmetrically distributed clamping modules. Each clamping module includes a clamping member and a rotary cylinder driven and connected thereto. The linear module includes a set of linear guide rails arranged at intervals, a linear slider that slides with the linear guide rails, and a telescopic cylinder. The rotary cylinder is fixedly installed on the end face of the linear slider and moves with it.

[0007] Preferably, the linear guide rail extends along the length of the worktable, a connecting plate is provided between a group of linear sliders, and the telescopic shaft of the telescopic cylinder is drivenly connected to the connecting plate.

[0008] Preferably, the screen printing assembly includes a screen, a squeegee disposed above the screen, a squeegee blade, and an axial moving module for driving the squeegee and squeegee blade to move axially.

[0009] Preferably, the axial movement module includes an axial guide rail, an axial slider that slides with the axial guide rail, and a servo motor. The axial slider is provided with a cantilever connected to it, and the doctor blade and doctor knife are spaced apart on the front side of the cantilever.

[0010] Preferably, the cantilever is provided with a first lifting cylinder and a second lifting cylinder, the first lifting cylinder being drivenly connected to the doctor blade, and the second lifting cylinder being drivenly connected to the doctor blade.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By setting up a substrate rotation assembly and a linear module for driving the substrate rotation assembly to make linear displacement movements, after the substrate completes the first side printing process, the telescopic cylinder drives the linear slider to move backward a certain distance, thereby moving the substrate away from the screen. Then, the rotary cylinder drives the clamping parts to flip, thereby causing the substrate to flip. The telescopic cylinder drives the linear slider to move forward a certain distance, thereby moving the substrate under the screen for the second side printing. During the printing process, the servo motor drives the axial slider to slide along the length of the axial guide rail, thereby driving the squeegee and squeegee blade to scrape ink. The ink is transferred through the screen to the substrate, which can greatly improve the double-sided printing efficiency of the substrate. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-2 As shown, this utility model provides a rotary printing mechanism, including a worktable 2. A mounting frame and a screen printing assembly are provided on one side of the worktable 2. The mounting frame includes a guide rail mounting plate and a set of support plates 13. The screen printing assembly includes a screen 16, a doctor blade 3 disposed above the screen 16, a doctor blade 15, and an axial moving module for driving the doctor blade 3 and doctor blade 15 to move axially. The axial moving module includes an axial guide rail 9, an axial slider 10 slidingly engaged with the axial guide rail 9, and a servo motor 8. The axial slider 10 is provided with a cantilever 11 connected to it. A axial guide rail 9 is fixedly installed on the end face of the guide rail mounting plate and extends along its length. The doctor blade 3 and doctor knife 15 are spaced apart on the front side of the cantilever 11. The cantilever 11 is equipped with a first lifting cylinder 12 and a second lifting cylinder 14. The first lifting cylinder 12 is driven to the doctor blade 3, and the second lifting cylinder 14 is driven to the doctor knife 15. The worktable 2 is equipped with a substrate rotation assembly on the side away from the screen printing assembly, and the worktable 2 is equipped with a linear module for driving the substrate rotation assembly to perform linear displacement motion. The linear module includes a set of linear guides spaced apart. The system comprises a linear guide rail 1, a linear slider 5 that slides with the linear guide rail 1, and a telescopic cylinder 17. The rotary cylinder 7 is fixedly mounted on the end face of the linear slider 5 and moves with it. The linear guide rail 1 extends along the length of the worktable 2. A connecting plate 18 is provided between a group of linear sliders 5. The telescopic shaft of the telescopic cylinder 17 is drivenly connected to the connecting plate 18. The substrate rotation assembly includes a set of symmetrically distributed clamping modules. The clamping modules include clamping parts 6 and a rotary cylinder 7 drivenly connected to them. After the substrate 4 completes the first printing process, the telescopic cylinder 17 drives the linear guide rail 17 to rotate. The slider 5 moves backward a certain distance, thereby moving the substrate 4 away from the screen 16. Then, the rotary cylinder 7 drives the clamping part 6 to flip, thereby causing the substrate 4 to flip. The telescopic cylinder 17 drives the linear slider 5 to move forward a certain distance, thereby moving the substrate 4 to the bottom of the screen 16 for the second side printing. During the printing process, the servo motor 8 drives the axial slider 10 to slide along the length direction of the axial guide rail 9, thereby driving the squeegee 3 and squeegee blade 15 to scrape ink. The ink is transferred through the screen to the substrate 4. The height of the squeegee 3 and squeegee blade 15 can be adjusted by the first lifting cylinder 12 and the second lifting cylinder 14.

[0019] Compared with traditional technology: By setting up a substrate rotation component and a linear module for driving the substrate rotation component to make linear displacement movements, after the substrate 4 completes the first side printing process, the telescopic cylinder 17 drives the linear slider 5 to move backward a certain distance, thereby moving the substrate 4 away from the screen 16. Then, the rotary cylinder 7 drives the clamping part 6 to flip, thereby moving the substrate 4 to flip. The telescopic cylinder 17 drives the linear slider 5 to move forward a certain distance, thereby moving the substrate 4 to below the screen 16 for the second side printing. During the printing process, the servo motor 8 drives the axial slider 10 to slide along the length direction of the axial guide rail 9, thereby driving the squeegee 3 and squeegee blade 15 to scrape ink. The ink is transferred through the screen to the substrate 4, which can greatly improve the double-sided printing efficiency of the substrate 4.
