Description

Technical Field

[0001] This utility model relates to the field of printing and packaging equipment technology, specifically to a flipping device for color printing of paper boxes. Background Technology

[0002] A flipping device for paper box color printing is an automated device that can automatically grab the cardboard with one side already printed and flip it 180 degrees during the paper box color printing process to achieve accurate printing on the other side.

[0003] Traditional flipping devices have poor adaptability to different sizes of cardboard. Their gripping and limiting structures are mostly designed with fixed specifications, which cannot flexibly adjust the fixing range and support spacing according to changes in cardboard size. When handling cardboard with large size differences, the cardboard is prone to tilting or shifting during the flipping process due to the fixing point deviating from the center of gravity of the cardboard or insufficient limiting. This not only requires manual stopping for adjustment, but also reduces the positional accuracy of the cardboard after flipping, directly affecting the pattern alignment effect of subsequent printing processes, reducing product qualification rate and production efficiency. In addition, the fixing range of traditional flipping devices is small, and the support area for the cardboard is limited. Especially when handling large-sized or thin cardboard, the unfixed areas of the cardboard are prone to deformation under the centrifugal force of flipping or its own gravity, which can lead to damage such as cardboard breakage and surface wrinkles, increasing raw material waste.

[0005] Therefore, the purpose of this utility model is to provide a flipping device for color printing of paper boxes, which solves the problems of poor adaptability of traditional flipping devices for color printing of paper boxes due to the fixed gripping and limiting structure and small fixing range, and the easy deformation, breakage and wrinkling of large / thin paper boxes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A flipping device for color printing of paper boxes includes a base, with conveyor rollers fixedly connected to the top four sides of the base. A U-shaped support is fixedly connected to the top of the base via a lifting support mechanism. A support arm is rotatably connected between the two ends of the U-shaped support. A servo motor is fixedly connected to the side wall of the U-shaped support. One end of the servo motor passes through the side wall of the U-shaped support and is fixedly connected to the shaft of the support arm. A T-shaped support plate is fixedly connected to the other end of the support arm. The T-shaped support plate has connecting compartments fixedly connected to both side walls. The bottom of the T-shaped support plate has a first sliding opening and a first limiting slide plate is slidably connected thereto.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a flipping device for color printing of paper boxes.

[0020] This utility model provides, for example Figure 1-4 The flipping device for color printing of paper boxes shown includes a base 1. Conveying roller devices 2 are fixedly connected to the top four sides of the base 1. A U-shaped support seat 3 is fixedly connected to the top of the base 1 through a lifting support mechanism. A support arm 4 is rotatably connected between the two ends of the U-shaped support seat 3. A servo motor 5 is fixedly connected to the side wall of the U-shaped support seat 3. One end of the servo motor 5 passes through the side wall of the U-shaped support seat 3 and is fixedly connected to the shaft of the support arm 4. A T-shaped support plate 6 is fixedly connected to the other end of the support arm 4. Connecting chambers 7 are fixedly connected to both side walls of the T-shaped support plate 6. A first sliding opening 8 is provided at the bottom of each T-shaped support plate 6, and a first limiting slide plate 9 is slidably connected thereto. A first electric push rod 10 is fixedly connected to one end of the cavity of the T-shaped support plate 6. One end of the first electric push rod 10 is fixedly connected to the side wall of the first limiting slide plate 9. A push-off plate 11 is fixedly connected to the bottom of the first limiting slide plate 9. An adjusting plate 12 is fixedly connected to one end of each connecting chamber 7 via a drive mechanism. An adsorption plate assembly 13 is fixedly connected to the top of both adjusting plates 12 and the connecting chamber 7. The side wall of the base 1 is fixedly connected to... Equipped with a display controller 14, the automated conveying of cartons is achieved using the conveyor roller device 2, reducing manual intervention and improving production efficiency. The height of the U-shaped support base 3 can be adjusted using the lifting support mechanism to accommodate cartons of different thicknesses or conveying heights. The U-shaped support base 3 provides rotational mounting space for the support arm 4, ensuring stable operation. The servo motor 5 provides precise driving force, controlling the flipping angle and speed of the support arm 4 to prevent deformation of the cartons due to excessive flipping. The support arm 4 drives the T-shaped support plate 6 to flip, thus achieving carton flipping. The mechanism utilizes a T-shaped support plate 6 to provide a mounting carrier for the subsequent gripping and limiting components, ensuring a compact structure. A connecting compartment 7 provides installation space for the drive mechanism and supports the adsorption plate assembly 13. A first sliding opening 8 provides a sliding guide for the first limiting slide plate 9, ensuring smooth movement of the pusher plate 11. A first electric push rod 10 adjusts the position of the pusher plate 11 to accommodate different sized cardboard boxes, enabling precise unloading after flipping. The pusher plate 11 prevents the cardboard box from sticking to the adsorption components after flipping, ensuring smooth unloading. The drive mechanism... The position of the adjustable plate 12 can be expanded to increase the gripping range of the adsorption plate assembly 13, thereby improving the adaptability of paper boxes of different sizes. The adsorption plate assembly 13 is used to grip the paper box by adsorption, avoiding deformation or wrinkles caused by mechanical clamping. The display controller 14 can monitor the equipment operating parameters in real time, which is convenient for operators to make precise adjustments and improves the ease of operation. This solves the problem that traditional paper box color printing flipping devices have poor adaptability to different sizes of paperboard due to fixed gripping and limiting structures and small fixed range, and large / thin paperboards are prone to deformation, breakage and wrinkles. To achieve height adjustment of the U-shaped support 3 and adapt to different paper box conveying requirements, such as... Figure 1 and 2As shown, the lifting support mechanism includes a guide chamber 15, a guide slide 16, a support column 17, and a hydraulic rod 18. The guide chamber 15 is fixedly connected to the top of the base 1. The guide slide 16 is opened in the cavity of the guide chamber 15 and is slidably connected to the support column 17. The hydraulic rod 18 is fixedly connected to the bottom of the cavity of the guide chamber 15. One end of the hydraulic rod 18 is fixedly connected to the bottom of the support column 17. The top of the support column 17 is fixedly connected to the bottom of the U-shaped support seat 3. The guide chamber 15 provides lifting and installation space for the support column 17 to ensure structural stability. The guide slide 16 provides sliding guidance for the support column 17 to prevent deviation during lifting. The hydraulic rod 18 provides stable driving force, which can accurately control the lifting height of the support column 17, adapting to cardboard boxes of different thicknesses or conveying heights, improving the versatility of the device. The support column 17 transmits the power of the hydraulic rod 18 to the U-shaped support seat 3 to ensure smooth height adjustment.

[0021] To adjust the spacing of the adsorption plate assembly 13 and adapt to different sized cardboard boxes, such as... Figure 1-4 As shown, the driving mechanism includes a second electric push rod 19, a second limiting slide 20, and a second limiting slide plate 21. The second electric push rod 19 is fixedly connected to the cavity of the connecting compartments 7 at both ends. The other end of the second electric push rod 19 at both ends is fixedly connected to the side wall of the corresponding adjusting plate 12. The top of the connecting compartments 7 at both ends is provided with a second limiting slide 20, and the second limiting slide plate 21 is slidably connected thereto. The side wall of the second limiting slide plate 21 at both ends is fixedly connected to the side wall of the corresponding adjusting plate 12. The second electric push rod 19 provides precise driving force, and the position of the adjusting plate 12 can be adjusted according to the size of the cardboard box, thereby changing the spacing of the adsorption plate assembly 13. It can adapt to different specifications of products, from small card boxes to large cartons. The second limiting slide 20 provides sliding guidance for the second limiting slide plate 21 to prevent the adjusting plate 12 from shifting when moving. The second limiting slide plate 21 enhances the connection stability between the adjusting plate 12 and the connecting compartment 7, ensuring that the adsorption plate assembly 13 does not shake during gripping and flipping, and avoiding deformation of the cardboard box. To provide a stable negative pressure for the adsorption plate assembly 13 and ensure a firm grip on the cardboard box, such as Figure 1 and 2As shown, a negative pressure generating device 22 is fixedly connected inside the cavity of the base 1. An adapter 23 is fixedly connected to the negative pressure suction port of the negative pressure generating device 22. Adapter plates 24 are fixedly connected to both ends of the adapter 23 through openings. The suction pipe ends at the top of the adapter plates 24 are fixedly connected to the air outlets of the corresponding adsorption plate assemblies 13. The negative pressure generating device 22 generates a stable negative pressure to provide continuous adsorption force to the adsorption plate assemblies 13, ensuring that the cardboard box does not fall off during the flipping process. The adapter 23 connects the negative pressure generating device 22 and the adapter plates 24, and simultaneously distributes the negative pressure to multiple adsorption plate assemblies 13. The adapter plates 24 evenly distribute the negative pressure to each adsorption plate assembly 13, ensuring that the adsorption force at each adsorption point is consistent, avoiding wrinkles in the cardboard box due to uneven force. The overall negative pressure pipeline design is simple, easy to maintain, and improves adsorption reliability. To protect the cardboard box and enhance the unloading effect, such as Figure 4 As shown, a silicone cushioning anti-slip pad 25 is fixedly connected to the side wall of the push plate 11. The silicone cushioning anti-slip pad 25 is soft and can prevent the corners from being crushed or scratched due to hard contact between the push plate 11 and the cardboard box. At the same time, its anti-slip properties can enhance the friction with the cardboard box, ensuring that the cardboard box does not slip during push-out, achieving accurate material feeding and reducing production stoppages caused by poor push-out. To improve the durability and adsorption sealing of the adsorption plate assembly 13, such as Figure 1 , 2 As shown in Figure 4, each adsorption plate assembly 13 includes a hollow plate 26. The bottom of the hollow plate 26 has multiple adsorption holes 27 and is fixedly connected with a sealing lip ring 28. The cavity of the hollow plate 26 and the walls of the adsorption holes 27 are coated with polytetrafluoroethylene. The hollow plate 26 provides storage and distribution space for negative pressure, ensuring uniform adsorption force of the adsorption holes 27. The multiple adsorption holes 27 disperse the adsorption force, avoiding excessive local pressure that could cause deformation of the thin paper box. The sealing lip ring 28 can fit against the surface of the paper box, enhancing the adsorption seal. Even if the surface of the paper box has slight unevenness, it can still ensure firm adsorption and reduce negative pressure leakage. The polytetrafluoroethylene coating has low friction and corrosion resistance properties, which can prevent ink from sticking to the adsorption holes 27, while extending the service life of the hollow plate 26 and reducing the cleaning frequency.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
