Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to an automated screen printing device for glass bottle processing. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to screen printing is also constantly improving. The three major printing methods, flat printing, letterpress printing and gravure printing, can generally only be used on flat substrates. However, screen printing can be used not only on flat surfaces, but also on curved and uneven substrates, making it suitable for printing on glass bottles.

[0003] The patent document with publication number "CN220409956U" discloses an automated screen printing device for glass bottle processing, which relates to the field of screen printing processing technology and includes a main mounting frame, a screen printing processing unit and a bottle conveying unit.

[0004] Although the aforementioned patent documents have solved the problems of poor adhesion between the bottle and the printing screen, which prevents the ink from adhering properly to the bottle, the following drawbacks still exist: when the glass bottle enters the device from the hopper, environmental dust, residual impurities in the hopper, or fingerprints left by human contact easily adhere to its surface. After the glass bottle directly enters the screen printing process, these impurities can cause the ink to not adhere evenly, resulting in defects such as pinholes, ink gaps, and blurred patterns, which seriously affect the printing quality. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the prior art: when glass bottles enter the device from the feeding hopper, environmental dust, residual impurities in the feeding hopper, or fingerprints left by human contact easily adhere to the surface. After the glass bottles directly enter the screen printing process, the impurities will cause the ink to not adhere evenly, forming defects such as pinholes, ink shortages, and blurred patterns, which seriously affect the printing quality. Therefore, an automated screen printing device for glass bottle processing is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated screen printing device for glass bottle processing includes a mounting frame and a feeding hopper. Two support frames with L-shaped cross-sections are mounted on the mounting frame. The two support frames are connected by a telescopic rod. Multiple upper dust-adhesive rollers and multiple lower dust-adhesive rollers are arranged between the two support frames. Each upper dust-adhesive roller and each lower dust-adhesive roller is provided with dust-adhesive paper.

[0008] Multiple rotating grooves are provided on one side surface of each of the two support frames, and multiple rotating rods are rotatably arranged between the multiple rotating grooves. Each lower dust-adhesive roller is rotatably sleeved on the outside of the corresponding rotating rod. Multiple rectangular rods are arranged between the two support frames, and each upper dust-adhesive roller is sleeved on the outside of the corresponding rectangular rod. A drive assembly is provided on the support frame.

[0009] Preferably, one of the support frames is rotatably connected to a plurality of rotating cylinders, each of the rotating cylinders having a rectangular opening for connecting the rectangular rod, and the other support frame is rotatably connected to a plurality of rectangular sleeves, each of the rectangular sleeves being fitted over the corresponding rectangular rod.

[0010] Preferably, the drive assembly includes a plurality of servo motors fixedly mounted on the support frame, and the drive end of each servo motor is fixedly connected to the corresponding rectangular sleeve.

[0011] Preferably, one of the support frames is threadedly connected to a threaded rod, and the other support frame is rotatably connected to the threaded rod.

[0012] Preferably, an L-shaped strip is fixedly connected to one side of each support frame, and two positioning sleeves for connecting the L-shaped strip are fixedly connected to the mounting bracket.

[0013] Preferably, each of the support frames is slidably connected to an E-shaped rod, one end of which passes through the positioning sleeve and engages with the L-shaped strip. A spring is fitted on the E-shaped rod, one end of which is fixedly connected to the support frame, and the other end of which is fixedly connected to the E-shaped rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Thoroughly removes dust and improves screen printing quality. The upper and lower dust rollers, together with the dust paper, thoroughly remove dust, impurities and fingerprints from the surface of glass bottles, solving the ink adhesion defects caused by direct screen printing, making the screen printed pattern clear and uniform, and greatly improving the yield.

[0016] Easy to install and maintain, the snap-fit ​​structure between the E-shaped rod and the positioning sleeve enables quick disassembly and assembly of the support frame, the adhesive paper can be easily replaced, and the servo motor driven adhesive roller has a stable structure and is easy to maintain, improving operation and maintenance efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-4 An automated screen printing device for glass bottle processing includes a mounting frame 1 and a feeding hopper 2. Two support frames 3 with L-shaped cross-sections are mounted on the mounting frame 1. The two support frames 3 are connected by a telescopic rod 11, with both ends of the telescopic rod 11 fixedly connected to the two support frames 3 respectively. Multiple upper dust-adhesive rollers 10 and multiple lower dust-adhesive rollers 9 are arranged between the two support frames 3. Each upper dust-adhesive roller 10 and each lower dust-adhesive roller 9 is provided with dust-adhesive paper. Multiple rotating grooves 15 are opened on one side surface of each of the two support frames 3. Multiple rotating rods 16 are rotatably arranged between the multiple rotating grooves 15. Each lower dust-adhesive roller 9 is rotatably sleeved on the outside of the corresponding rotating rod 16. Multiple rectangular rods 12 are arranged between the two support frames 3. Each upper dust-adhesive roller 10 is sleeved on the outside of the corresponding rectangular rod 12. A drive assembly is provided on the support frame 3.

[0025] Multiple rotating cylinders 14 are rotatably connected to one of the support frames 3. Each rotating cylinder 14 has a rectangular opening for connecting a rectangular rod 12. Multiple rectangular sleeves 13 are rotatably connected to the other support frame 3. Each rectangular sleeve 13 is fitted over the corresponding rectangular rod 12. The drive assembly includes multiple servo motors fixedly installed on the support frame 3. The drive end of each servo motor is fixedly connected to the corresponding rectangular sleeve 13. The servo motors are used to drive the rectangular rod 12 and the upper dust roller 10 to rotate.

[0026] One of the support frames 3 is threadedly connected to a threaded rod 5, and the other support frame 3 is rotatably connected to the threaded rod 5. Rotating the threaded rod 5 can adjust the distance between the two support frames 3. An L-shaped strip 4 is fixedly connected to one side of each support frame 3. Two positioning sleeves 6 for connecting the L-shaped strips 4 are fixedly connected to the mounting bracket 1. The L-shaped strips 4 are inserted into the positioning sleeves 6 to achieve the initial installation and positioning of the support frame 3.

[0027] Each support frame 3 is slidably connected to an E-shaped rod 7. One end of the E-shaped rod 7 passes through the positioning sleeve 6 and is engaged with the L-shaped strip 4. A spring 8 is fitted on the E-shaped rod 7. One end of the spring 8 is fixedly connected to the support frame 3, and the other end of the spring 8 is fixedly connected to the E-shaped rod 7. Under the elastic force of the spring 8, one end of the E-shaped rod 7 passes through the positioning sleeve 6 and is engaged with the L-shaped strip 4, which can effectively prevent the L-shaped strip 4 from detaching from the positioning sleeve 6 at will.

[0028] In this invention, rotating the threaded rod 5, in conjunction with the telescopic rod 11, adjusts the distance between the two support frames 3, pulls the E-shaped rod 7 to compress the spring 8, inserts the L-shaped strip 4 into the positioning sleeve 6 and then releases it. The spring 8 returns to its original position, causing the E-shaped rod 7 to engage with the L-shaped strip 4, thus fixing the support frame 3. After the glass bottle enters from the feed hopper 2, it enters between the upper dust-adhesive roller 10 and the lower dust-adhesive roller 9. The servo motor starts, driving the rectangular sleeve 13 and the rectangular rod 12 to rotate, which in turn drives the upper dust-adhesive roller 10 to rotate. The lower dust-adhesive roller 9 moves with the glass bottle and rotates passively due to friction with the upper dust-adhesive roller 10. The dust-adhesive paper adsorbs dust, impurities, and fingerprints on the surface of the glass bottle, achieving efficient dust removal. The cleaned glass bottle is then transported to the subsequent screen printing process. Because the surface is clean, the ink can adhere evenly, avoiding defects such as pinholes and ink shortages.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to mechanical connection or electrical connection; they can refer to direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
