Description

Technical Field

[0001] This utility model relates to the field of material printing technology, specifically a double-sided multi-color printing line device. Background Technology

[0002] Double-sided multi-color line printing equipment is a specialized printing processing equipment that can print simultaneously or in stages on both sides of the substrate and can continuously print two or more different colors of lines, markings, and patterns. It is an integrated special printing equipment that can accurately print multiple colors of lines on both sides of the material. It is mainly used for double-sided multi-color line precision printing on materials such as rolls, sheets, films, paper, and plastic sheets.

[0003] Existing double-sided multi-color printing line equipment mostly uses manual bolt adjustment of the distance between the printing line roller and the pressure roller. The adjustment accuracy is low, the time is long, and it is difficult to accurately control the printing pressure. Problems such as excessive pressure causing the roll material to stretch and deform, and line smudging, or insufficient pressure causing light lines, missing prints, and broken lines are common. The multi-color lines are uneven in thickness, the double-sided line alignment accuracy is low, and the defect rate is high. In addition, the ink collection box is often fixed by screws or welded. When cleaning or replacing the ink collection box, multiple screws must be removed with tools. The operating space is small, the time is long, and the printing efficiency is affected. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided multi-color printing line device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-sided multi-color printing line device, comprising a frame, a support, and a base. The support is installed on both sides inside the frame, and the base is connected to both sides at the top of the support. A protective box is connected to the middle of the top of the base. A helical gear is rotatably connected inside the protective box. An anilox roller is rotatably connected to the middle of the inner wall of the protective box. An ink roller is rotatably connected to one side of the inner wall, and a printing line roller is rotatably connected to the other side. A pressure roller is connected to the inner wall of the frame near the printing line roller. An electric push rod is fixedly connected to one side of the bottom of the base. A base is provided on the outer wall of the ink roller. An ink collection box is fixedly connected to the bottom of the base. A base plate is slidably connected to the bottom of the ink collection box. A limit block is fixedly connected to one side of the top of the base plate. The electric push rod can drive the base to move linearly, which is used to adjust the distance between the printing roller and the pressure roller; the base plate is used to support the ink collection box, and the limiting block is used to initially limit the base plate; The base is connected to fixed seats on both sides of the top. The bottom of the fixed seat is slidably connected to a limiting component, and the outer wall of the limiting component is slidably connected to a positioning seat. The bottom of the limiting component is connected to a spring. A guide slope is provided on one side of the bottom of the outer wall of the fixed seat. The spring is used to drive the limiting member to move upward. A guide slope corresponding to the guide slope is opened on one side of the top of the limiting member, which works with the spring to realize the insertion and locking of the base.

[0006] Preferably, the base has sliding grooves on both sides of its bottom end, and limit pins are connected inside the sliding grooves to guide the base to move smoothly. The base plate and the limit block are combined in a "T" shape, and the outer wall of the base plate is fixedly connected to the protective box.

[0007] The electric push rod can drive the base to move linearly, precisely adjusting the gap and printing pressure between the printing roller and the pressure roller, adapting to roll materials of different thicknesses.

[0008] Preferably, the bottom end of the spring is fixedly connected to the positioning seat and the limiting member, the positioning seat and the spring form an elastic telescopic mechanism, the base is U-shaped and the two sides of the middle part are provided with grooves corresponding to the positioning seat.

[0009] The moving base moves the ink collection box closer to the positioning seat. During this process, the guide slope on the outer wall of the fixed seat presses against the guide slope on the top of the limiting component, causing the limiting component to compress the spring downwards. Until the ink collection box moves below the anilox roller and the ink roller, the spring rebounds and moves the limiting component upwards into the fixed seat, thereby engaging the fixed base and achieving quick insertion and locking of the base.

[0010] Preferably, a pressing member is slidably connected to the top of the fixed base, a diagonal rod is connected to the top of the pressing member, and a transmission plate is fixedly connected to the top of the diagonal rod. Slider blocks with equal intervals are connected to the middle of the transmission plate.

[0011] Preferably, the base has a movable groove in the middle corresponding to the slider, and a sliding plate is connected to one side of the outer wall of the slider. Pressing the sliding plate can move the pressing component down and unlock the base to move out of the ink collection box.

[0012] Press the slide plate, and the slide plate will drive the slider to slide along the movable groove, driving the transmission plate to press down. The inclined rod will push the pressing part to move down, and the pressing part will squeeze the limiting part until the limiting part moves out of the fixed seat, releasing the base from locking. Then, the base and ink collection box can be pulled out as a whole to complete the replacement and cleaning of the ink collection box.

[0013] As can be seen from the above, the double-sided multi-color printing line equipment provided by this utility model has the following beneficial effects.

[0014] By using an electric push rod in conjunction with a limit pin to drive the base displacement, the printing pressure and spacing of the printing roller and the pressure roller can be adjusted, making it suitable for roll materials of different thicknesses and materials. It has a wide range of applications and produces uniform and clear printed lines.

[0015] By setting up a base, ink collection box, bottom plate and limit block, the ink collection box can be disassembled as a whole; the base can be automatically locked by springs, limit parts and guide slopes, and can be quickly unlocked and disassembled by pressing the slide plate, which simplifies the operation process of ink replacement, ink box cleaning and roller maintenance, and shortens the equipment downtime for maintenance.

[0016] The flexible telescopic locking structure, combined with the linkage unlocking structure of the diagonal rod and transmission plate, ensures structural stability, effortless assembly and disassembly, precise positioning, and prevents ink cartridge misalignment during installation.

[0019] 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.

[0020] Please see Figures 1-9 This utility model provides a technical solution: a double-sided multi-color printing line device, including a frame 1, a support 2, and a base 3. The support 2 is symmetrically installed on the upper and lower sides inside the frame 1, and the base 3 is connected to the top two sides of the support 2 respectively. The upper and lower sets of base 3 constitute the front and back printing units, realizing synchronous double-sided printing of roll material. A protective box 4 is connected to the middle of the top of the base 3. A helical gear is rotatably connected inside the protective box 4 to transmit power and drive the rollers to rotate synchronously. An anilox roller 5 is rotatably connected to the middle of the inner wall of the protective box 4 for quantitative ink transfer. An ink roller 6 is rotatably connected to one side of the inner wall of the base 3, and a printing line roller 7 is rotatably connected to the other side. The surface of the printing line roller 7 is engraved with multi-color line patterns to realize multi-color line printing. A pressure roller 8 is connected to the inner wall of the frame 1 near the printing line roller 7. The pressure roller 8 cooperates with the printing line roller 7 to provide printing pressure for the roll material.

[0021] An electric push rod 9 is fixedly connected to one side of the bottom end of the base 3. Slide grooves are opened inside the two sides of the bottom end of the base 3. Limit pins 10 are connected inside the slide grooves. The limit pins 10 guide the movement of the base 3 to ensure that the base 3 moves smoothly in a straight line. The electric push rod 9 can drive the base 3 to move in a straight line, accurately adjust the distance and printing pressure between the printing roller 7 and the pressure roller 8, and adapt to roll materials of different thicknesses.

[0022] The outer wall of the ink roller 6 is provided with a base 11, which has a U-shaped structure. The bottom end of the base 11 is fixedly connected to an ink collection box 12 for receiving dropped ink. The bottom end of the ink collection box 12 is slidably connected to a base plate 13. The outer wall of the base plate 13 is fixedly connected to the protective box 4. A limit block 14 is fixedly connected to one side of the top of the base plate 13. The base plate 13 and the limit block 14 are combined to form a T-shaped structure. The limit block 14 limits the base plate 13 to prevent the base plate 13 from shifting laterally. The base plate 13 stably supports the ink collection box 12.

[0023] The base 11 has fixed seats 15 connected to both sides of its top end. The bottom of the fixed seat 15 is slidably connected to a limiting member 16. The outer wall of the limiting member 16 is slidably connected to a positioning seat 17. The middle of the base 11 has a groove corresponding to the positioning seat 17. The bottom of the limiting member 16 is connected to a spring 18. The bottom of the spring 18 is fixedly connected to the positioning seat 17. The limiting member 16, the positioning seat 17 and the spring 18 form an elastic telescopic mechanism. The bottom of the outer wall of the fixed seat 15 has a guide slope 19. The top of the limiting member 16 has a guide slope corresponding to the guide slope 19.

[0024] When installing the ink collection box 12, first move the base 11 to bring the ink collection box 12 closer to the positioning seat 17. During this process, the guide slope 19 on the outer wall of the fixed seat 15 presses against the guide slope at the top of the limiting member 16, causing the limiting member 16 to compress the spring 18 and move downward. Until the ink collection box 12 moves below the anilox roller 5 and the ink roller 6, the spring 18 rebounds and drives the limiting member 16 to move upward into the fixed seat 15, thereby engaging the fixed base 11 and realizing the quick insertion and locking of the base 11.

[0025] The top of the fixed base 15 is slidably connected to a pressing member 20. The top of the pressing member 20 is hinged to a diagonal rod 21. The top of the diagonal rod 21 is fixedly connected to a transmission plate 22. The middle of the transmission plate 22 is connected to equally spaced sliders 23. The middle of the base 11 has a movable groove corresponding to the slider 23. The outer wall of the slider 23 is connected to a sliding plate 24.

[0026] When it is necessary to disassemble and clean the ink collection box 12, press the slide plate 24. The slide plate 24 drives the slider 23 to slide along the movable groove, driving the transmission plate 22 to press down. The inclined rod 21 pushes the pressing member 20 to move down. The pressing member 20 squeezes the limiting member 16 until the limiting member 16 moves out of the fixed seat 15, releasing the lock of the base 11. Then, the base 11 and the ink collection box 12 are pulled out as a whole to complete the replacement and cleaning of the ink collection box 12. A tension spring is installed inside the movable groove to reset the slider 23.

[0027] When this equipment is working, the roll material is fed at a uniform speed between the pressure roller 8 and the printing roller 7. The upper and lower printing units work synchronously. The ink is transferred from the ink collection box 12 through the ink roller 6 and the anilox roller 5 to the printing roller 7. The electric push rod 9 adjusts the printing pressure and completes the double-sided multi-color line printing of the roll material in one go.

[0028] This solution uses an electric push rod 9 in conjunction with a limit pin 10 to drive the base 3 to move, which can adjust the printing pressure and spacing of the printing roller 7 and the pressure roller 8. It is suitable for roll materials of different thicknesses and materials, has a wide range of applications, and produces uniform and clear printing lines.

[0029] By setting up a base 11, an ink collection box 12, a base plate 13, and a limiting block 14, the ink collection box 12 can be disassembled as a whole; the base 11 can be automatically locked by a spring 18, a limiting component 16, and a guide slope 19, and can be quickly unlocked and disassembled by pressing the sliding plate 24, which simplifies the operation process of ink replacement, ink box cleaning, and roller maintenance, and shortens the equipment downtime for maintenance.

[0030] The flexible telescopic locking structure, combined with the linkage unlocking structure of the diagonal rod 21 and the transmission plate 22, ensures structural stability, ease of disassembly and assembly, and precise positioning, thus preventing the ink collection box 12 from being misaligned during installation.

[0031] In practice, first install two sets of brackets 2 inside the frame 1 on the upper and lower sides, and assemble the base 3 accordingly. Then, install the anilox roller 5, ink roller 6, and printing line roller 7 in the base 3 in sequence, and install the pressure roller 8 at the corresponding position on the frame 1. Fix the protective box 4 on the top of the base 3 to complete the assembly of the helical gear transmission structure and ensure that each roller can rotate synchronously.

[0032] Next, the base plate 13 is fixed on the protective box 4, and the limiting block 14 and the base plate 13 form a T-shaped limiting structure. During the insertion process, the guide slope 19 of the fixing seat 15 presses the guide slope of the limiting member 16, and the limiting member 16 compresses the spring 18 and moves down. After the base 11 is in place, the spring 18 rebounds and drives the limiting member 16 to move up and lock the fixing seat 15, thus completing the quick locking installation of the base 11 and the ink collection box 12.

[0033] The roll of material to be printed is then inserted sequentially between the upper and lower sets of pressure rollers 8 and printing rollers 7 to ensure that the roll is flat and wrinkle-free. The electric push rod 9 is activated, and with the guidance of the limit pin 10, the base 3 is driven to move horizontally, adjusting the distance between the printing roller 7 and the pressure roller 8, and pre-adjusting to a suitable printing pressure according to the thickness of the roll.

[0034] Start the main motor of the equipment. The helical gear transmission in the protective box 4 drives the anilox roller 5, ink roller 6, and line printing roller 7 to rotate synchronously. The roll material is conveyed forward at a uniform speed, passing through the upper printing unit and the lower printing unit in sequence. The ink is transferred to the anilox roller 5 through the ink roller 6. The anilox roller 5 supplies ink to the line printing roller 7 in a quantitative manner. The line printing roller 7 and the pressure roller 8 work together to apply pressure, completing the synchronous printing of multi-color lines on both sides of the roll material in one go. During the printing process, the printing effect of the lines is observed in real time. The position of the base 3 is finely adjusted by the electric push rod 9 to correct the printing pressure, ensuring clear lines, accurate double-sided alignment, no ink bleeding, and no deviation.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
