Description

Technical Field

[0001] This utility model relates to the field of rapid assembly and disassembly and transmission technology, specifically a modular, rapid assembly and disassembly intelligent transmission device for slanted-back equipment. Background Technology

[0002] In fields such as packaging printing, electronic circuit manufacturing, and advertising signage production, screen printing has long held a core position due to its advantages of flexible pattern reproduction and wide material compatibility. However, as the market continues to upgrade its demands for product customization, printing precision, and long-term stable operation of equipment, the performance defects of existing screen printing transmission equipment have become increasingly prominent, becoming a key bottleneck restricting the industry's advancement.

[0003] Analyzing the screen printing plate assembly and disassembly process, traditional equipment requires tools to tighten the plates point by point during installation and reverses the process during disassembly, making it cumbersome. Furthermore, the relative positions of the screen printing plate and the printing table need to be repeatedly calibrated after assembly and disassembly, which is time-consuming and labor-intensive. In customized production scenarios, frequent order changes amplify the problem of low efficiency in screen printing plate changeovers. The idle time of the production line due to changeovers accounts for a high percentage, making it difficult to quickly respond to the diverse needs of the market and restricting production flexibility.

[0004] In terms of transmission operation, the sliding friction between the doctor blade assembly and the guide structure can easily lead to movement jamming, resulting in uneven doctor blade pressure and affecting printing quality. The transmission hinges lack self-lubricating design, causing rapid component wear and frequent maintenance. Furthermore, the doctor blade pressure adjustment method is rigid and cannot flexibly match the needs of different ink characteristics and substrate materials. In terms of energy consumption and stability, solid transmission components such as eccentric wheels and shafts are heavy, increasing the motor load. Rotational inertia can also cause start-stop shocks, exacerbating component fatigue and reducing equipment operating stability and lifespan. The rigid doctor blade pressure adjustment mechanism and cumbersome ink plate replacement cannot flexibly adapt to ink characteristics and substrate materials, limiting the equipment's ability to cover diverse production needs.

[0005] In summary, existing screen printing transmission equipment suffers from deficiencies in disassembly and assembly efficiency and transmission performance, failing to meet the industry's demands for efficient and flexible production and long-term stable operation. Therefore, we propose a modular, quick-disassembly, slanted-back intelligent transmission device to address these issues. Utility Model Content

[0015] This utility model provides a modular, quick-assembly and disassembly intelligent transmission device for slanted-back equipment, which has the following improvements and advantages compared with the prior art:

[0016] Firstly, this utility model achieves clamping and releasing of the squeegee by setting a pressing block and an eccentric handle, which allows for quick replacement of squeegee tools of different shapes and types. No auxiliary tools are required, and the twisting and pressing operations can be completed manually, reducing the skill threshold for workers and reducing equipment debugging time. It is especially suitable for production scenarios with frequent model changes. Through the integrated design of clamping bolts and flexible rubber suction cups, the screen plate can be quickly disassembled and assembled, avoiding damage to the screen plate caused by rigid contact. The annular adsorption groove enhances the sealing adsorption force and prevents the screen plate from shifting during printing. It is suitable for multi-variety, small-batch production modes and greatly improves the flexibility of the production line.

[0017] Secondly, this utility model effectively reduces its own weight by setting a hollow eccentric wheel and a surface hole design, thereby reducing the motor drive load and rotational inertia. The transmission impact during operation is greatly reduced, which not only improves the smoothness of the scraping action, but also reduces fatigue damage to components such as the motor and shaft, extending the equipment life. The combination of the self-lubricating copper sleeve and the wear-resistant nylon bushing enhances wear resistance and resists wear from long-term reciprocating motion. The ball bearings in the sliding sleeve and the round rod form a rolling fit, reducing frictional resistance and preventing the scraper from jamming. The coordinated design of the equipment achieves efficient and stable scraping action. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved modular, quick-assembly and disassembly intelligent transmission device for slanted-back equipment. The technical solution of this utility model is as follows:

[0027] like Figure 1 - Figure 4 As shown, a modular, quick-assembly, and detachable intelligent transmission device for slanted-back equipment includes a frame 1. A printing plate 2 is fixedly connected to the upper surface of the frame 1. A connecting rod 3 is fixedly connected to the inner wall of the frame 1. A roller 4 is rotatably connected to the upper part of the connecting rod 3 via a connecting block. An inclined frame 5 is rotatably connected to the upper surface of the frame 1. Two symmetrically arranged round rods 6 are fixedly connected to the surface of the inclined frame 5. The same sliding sleeve rod 7 is slidably connected to the surfaces of the two round rods 6. A support plate 8 is fixedly connected to the inner wall of the inclined frame 5. A motor 9 is fixedly connected to the upper surface of the support plate 8. A support rod 10 is fixedly connected to the upper surface of the inclined frame 5. The output end of the motor 9 is fixed... An eccentric wheel 11 is connected, and a rotating shaft 12 is fixedly connected to one end of the eccentric wheel 11. A transmission rod 13 is rotatably connected to one end of the rotating shaft 12. A scraper groove 14 is rotatably connected to the inner wall of the transmission rod 13. Two limit bolts 15 are provided on one side of the scraper groove 14. A scraper 16 is provided on the inner wall of the scraper groove 14. Multiple pressing blocks 17 are rotatably connected to the surface of the scraper groove 14 through connecting blocks. An eccentric handle 18 is rotatably connected to the inner wall of each of the multiple pressing blocks 17. Multiple clamping bolts 19 are provided on the inner wall of the inclined frame 5. The same wire mesh plate 20 is provided at the lower end of the multiple clamping bolts 19. The wire mesh plate 20 is slidably connected to the inner wall of the inclined frame 5.

[0028] Furthermore, the surface of the printing plate 2 is printed with scale lines for positioning the substrate along the length direction. The accuracy of the scale lines is ±0.5mm, which can realize the rapid positioning and calibration of the substrate, reduce the operation time of manual alignment, ensure the consistency of the substrate position during batch printing, reduce the printing defect rate caused by positioning deviation, and improve production efficiency and printing accuracy.

[0029] Furthermore, the inner wall of the inclined frame 5 is provided with threads, which match multiple clamping bolts 19. The clamping bolts 19 can be tightened or loosened quickly to achieve quick assembly and disassembly of the wire mesh plate 20, reduce the operation time for changing wire mesh plates 20 of different specifications, and improve the equipment changeover efficiency.

[0030] Furthermore, the inner wall of the sliding sleeve 7 is provided with threads, which match the two limit bolts 15. By adjusting the position of the two limit bolts 15, the rotation amplitude of the scraper groove 14 can be limited to adjust the scraping force, adapting to different printing scenarios, making it convenient and efficient, and improving the adaptability and ease of operation of the equipment.

[0031] Furthermore, the inner wall of the sliding sleeve 7 is provided with balls, which are slidably connected to the surfaces of the two round rods 6, significantly reducing frictional resistance and making the movement of the sliding sleeve 7 along the round rods 6 smoother and more stable. This reduces the problem of uneven ink scraping caused by friction jamming, while also reducing the wear rate of components and the frequency of equipment maintenance.

[0032] Furthermore, the eccentric wheel 11 has a hollow structure with multiple holes on its surface, which reduces the overall mass of the eccentric wheel 11, reduces the load and energy consumption when the motor 9 drives it, and also reduces rotational inertia, making the movement of the eccentric wheel 11 more stable, reducing the impact on the transmission components, and improving the stability of the equipment operation.

[0033] Furthermore, a self-lubricating copper sleeve is embedded at the rotatable connection between the transmission rod 13 and the rotating shaft 12, and a wear-resistant nylon bushing is fitted at the rotatable connection between the transmission rod 13 and the scraper groove 14. The self-lubricating copper sleeve can reduce the friction coefficient between the transmission rod 13 and the rotating shaft 12, eliminating the need for frequent lubrication and reducing maintenance costs. The wear-resistant nylon bushing can improve the wear resistance of the connection between the transmission rod 13 and the scraper groove 14, reducing component wear caused by long-term rotation. The combined effect of the two can ensure smooth operation of the transmission system, reduce motion noise, and improve the stability and service life of the equipment.

[0034] Furthermore, each of the lower ends of the multiple clamping bolts 19 is provided with a flexible rubber suction cup. The end face of the rubber suction cup is provided with an annular adsorption groove. The elasticity of the rubber suction cup can buffer the clamping force and avoid damage to the screen plate 20 caused by rigid contact. The annular adsorption groove can enhance the sealing adsorption force between the suction cup and the screen plate 20, prevent the screen plate 20 from shifting during the printing process, and take into account both the reliability of fixation and protection.

[0035] Working principle: Before printing, pressing and raising the eccentric handle 18 allows the pressing block 17 to squeeze the squeegee 16, fixing it in the clamping position within the squeegee groove 14. Rotating the clamping bolt 19 causes its lower suction cup to adhere tightly to the screen 20, enabling quick assembly and disassembly of the screen 20. Adjusting the positions of the two limiting bolts 15 within the sliding sleeve 7 limits the rotation of the squeegee groove 14, thus controlling the squeegee pressure of the squeegee 16 on the screen 20. Placing the substrate on the printing plate 2 and using the scale lines for quick positioning and calibration, starting the motor 9, whose output drives the eccentric wheel 11 to rotate. When roller 4 contacts the large-diameter outer ring of eccentric wheel 11, the force between roller 4 and eccentric wheel 11 causes support rod 10 to drive the entire upper structure of screen printing to rotate around the axis, forming the opening and closing between screen plate 20 and printing plate 2, so as to complete the replacement of the printing material one by one. When roller 4 contacts the small-diameter outer ring of eccentric wheel 11, rotating shaft 12 drives transmission rod 13 to swing back and forth. Transmission rod 13 drives the squeegee 16 in the squeegee groove 14 to perform the squeegee action. At the same time, the ball on the inner wall of sliding sleeve 7 slides and engages with the surface of round rod 6, guiding the squeegee 16 to move stably along round rod 6, avoiding friction and jamming, thereby completing the printing of the printing material.

[0036] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
