Technical Field

[0001] This utility model belongs to the field of cardboard box processing technology, and specifically relates to a cardboard box printing fixing device. Background Technology

[0002] Cardboard boxes, as a packaging material, play a vital role in logistics, warehousing, and transportation. With increasing market demand, the production efficiency and printing quality of cardboard boxes have become particularly important. The main raw material for cardboard box production is paper, including white cardboard, white board paper, coated paper, and kraft paper; some special cardboard boxes may also be made from specialty papers. Because cardboard boxes contain paper, they are renewable, biodegradable, and recyclable, making them an environmentally friendly packaging material.

[0003] In traditional cardboard box printing, due to the characteristics of the cardboard material, cartons are prone to springback and positional shifts on the conveyor belt due to friction, gravity, and other factors. This can lead to deviations in the printed pattern, affecting print quality and production efficiency, especially on high-speed printing production lines. Furthermore, traditional cardboard box printing fixtures are often complex in structure and difficult to adjust, failing to quickly adapt to the printing needs of cartons of different sizes, which also limits production efficiency and flexibility. Utility Model Content

[0004] To address the aforementioned problems, those skilled in the art have conducted extensive research and exploration, attempting to design a printing fixing device capable of adapting to cartons of different sizes, effectively fixing the position of cartons, and reducing printing deviations. This device needs to be easy to adjust, stable and reliable, and simple to operate, in order to meet the high efficiency and high quality requirements of modern carton printing production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cardboard box printing fixing device, comprising a frame, four of which are symmetrically arranged. A platform is fixedly connected to the top of each frame. A connecting block is fixedly connected to one side of each platform. Several connecting blocks are symmetrically arranged. Rollers are rotatably connected between adjacent connecting blocks. A conveyor belt is rotatably connected to the outer side of each roller. A motor is fixedly connected to one end of one roller. A connecting block is fixedly connected to one side of the motor. A first screw is threadedly connected to the top of the platform. Several first screws are symmetrically arranged.

A second screw is threadedly connected to one side of each side plate. An L-shaped plate is movably connected to the outer side of each second screw through a second limiting hole. A frame is fixedly connected to one side of each L-shaped plate. Rollers are rotatably connected to the inner side of each frame. Several rollers are symmetrically arranged. A top frame is fixedly connected to one side of the platform. A printing structure is fixedly connected to the inner side of the top frame.

[0006] Preferably, the tripods are fixedly connected to each other with stabilizing plates, and several stabilizing plates are symmetrically arranged.

[0007] Preferably, a storage frame is fixedly connected to one side of the tripod.

[0008] Preferably, both the first screw and the second screw are movably connected to a washer on their outer sides, the bottom end of the first screw is threadedly connected to a platform plate on its outer side, and the bottom end of the second screw is threadedly connected to a side plate on its outer side.

[0009] Preferably, the outer surface of the conveyor belt is symmetrically provided with a plurality of grooves, and a roller is rotatably connected to the inner side of the conveyor belt, with a transition block rotatably connected to both ends of the roller.

[0010] Preferably, both the first limiting hole and the second limiting hole are U-shaped structures. A first screw is movably connected to the inner side of the first limiting hole, and a second screw made of flexible material is movably connected to the inner side of the second limiting hole. Both ends of the roller are rotatably connected to a frame.

[0011] Preferably, a slider is fixedly connected to one side of each of the frame, and several sliders are symmetrically arranged. A side plate is slidably connected to the outer side of each slider.

[0012] Compared with the prior art, the present invention provides a cardboard box printing fixing device, which has the following beneficial effects:

[0013] This invention precisely adjusts the roller position to accommodate cartons of different sizes, effectively limiting the rebound and positional shift of the cartons during transport, thereby reducing printing pattern deviations and improving printing accuracy. The use of a first and second screw in conjunction with a U-shaped limiting hole makes horizontal and vertical roller adjustment simple and quick. Operators can quickly adjust the device according to the carton size, adapting to different carton sizes without complex adjustments, achieving fixed printing on cartons of various specifications, enhancing the flexibility and adaptability of the production line. The stabilizing plate fixed between the legs increases the overall structural stability, reducing vibration and displacement that may occur during high-speed printing, ensuring a smooth printing process. The rollers are made of flexible material, reducing wear on the cartons during fixing, protecting their integrity, and extending the rollers' lifespan. The use of shims reduces loosening of the first and second screws after prolonged use, while the slider design reduces top frame offset after long-term use, making device maintenance more convenient. Because the carton position is more reliably fixed, the printing press can operate at higher speeds without worrying about carton position shifts, thus improving overall production efficiency.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: a cardboard box printing fixing device, including a stand 1, four stands 1 symmetrically arranged, a platform 2 fixedly connected to the top of each stand 1, a connecting block 3 fixedly connected to one side of each platform 2, several connecting blocks 3 symmetrically arranged, rollers 4 rotatably connected between adjacent connecting blocks 3, a conveyor belt 6 rotatably connected to the outside of each roller 4, a motor 5 fixedly connected to one end of each roller 4, a connecting block 3 fixedly connected to one side of the motor 5, a first screw 7 threadedly connected to the top of the platform 2, several first screws 7 symmetrically arranged, a moving block 20 movably connected to the outside of each first screw 7 through a first limiting hole 8, a side plate 9 fixedly connected to one side of each moving block 20, a second screw 10 threadedly connected to one side of each side plate 9, an L-shaped plate 12 movably connected to the outside of each second screw 10 through a second limiting hole 11, a frame 13 fixedly connected to one side of each L-shaped plate 12, and a rotatably connected [missing information] to the inside of each frame 13. Rollers 14 are symmetrically arranged in several units. A top frame 15 is fixedly connected to one side of the platform 2, and a printing structure 16 is fixedly connected to the inner side of the top frame 15. According to the specific size of the carton, the first screw 7 and the second screw 10 are rotated in conjunction with the U-shaped first screw 7 and the second limiting hole 11 to adjust the rollers 14 in the horizontal and vertical directions to press the carton placed on top of the conveyor belt 6. The first screw 7 and the second screw 10 are rotated clockwise to fix the position of the rollers 14. The motor 5 is turned on to drive the roller 4 to rotate, and the conveyor belt 6 is turned on to carry out transmission. The cartons are placed one by one on top of the conveyor belt 6. The conveyor belt 6 moves the cartons. The rollers 14 can effectively limit the rebound of the carton. The printing structure 16 is turned on to print. This effectively reduces the situation where the carton itself rebounds due to the material during the conveying and printing process, causing positional deviation and resulting in deviation of the printed pattern.

[0022] In this utility model, preferably, the adjacent legs 1 are fixedly connected with stabilizing plates 21, and several stabilizing plates 21 are symmetrically arranged, which can effectively improve the stability of the legs 1 during use. A storage frame 18 is fixedly connected to one side of the legs 1 to effectively store the printed carton. The outer sides of the first screw 7 and the second screw 10 are movably connected with washers 19. The outer side of the bottom end of the first screw 7 is threadedly connected with a platform 2, and the outer side of the bottom end of the second screw 10 is threadedly connected with a side plate 9, which effectively reduces the loosening caused during long-term use. Several grooves are symmetrically arranged on the outer surface of the conveyor belt 6, and a roller 4 is rotatably connected to the inner side of the conveyor belt 6. Both ends of the roller 4 are rotatably connected with adapter blocks. 3. Effectively improves friction and reduces the slippage of the carton after placement. The first limiting hole 8 and the second limiting hole 11 are both U-shaped structures. The first limiting hole 8 is movably connected to the inner side of the first limiting hole 7, and the second limiting hole 11 is movably connected to the inner side of the second limiting hole 11. This effectively fine-tunes the position of the L-shaped plate 12 in the horizontal and vertical directions. The roller 14 is made of flexible material, and the outer sides of both ends of the roller 14 are rotatably connected to the frame 13, which effectively reduces the wear on the carton during the pressing and limiting process. A slider 17 is fixedly connected to one side of the frame 13. Several sliders 17 are symmetrically arranged, and the outer side of the slider 17 is slidably connected to the side plate 9, which effectively reduces the loosening of the frame 13 during long-term use.

[0023] The working principle and usage process of this utility model are as follows: When using the device, confirm the size of the carton to be printed and check whether the power supply, motor 5, and conveyor belt 6 are normal, ensuring all components are in usable condition. Based on the specific size of the carton, rotate the first screw 7 and the second screw 10, cooperating with the U-shaped first limiting hole 8 and the second limiting hole 11, to adjust the roller 14 horizontally and vertically to press down on the carton placed on top of the conveyor belt 6. Rotate the first screw 7 and the second screw 10 clockwise to fix the position of the roller 14, ensuring the roller 14 can stably press down on the carton. Turn on the motor 5 to drive the roller 4 to rotate, and start the conveyor belt 6 for transmission, preparing for carton transport. Place the cartons one by one on top of the conveyor belt 6. The conveyor belt 6 moves the cartons. The roller 14 effectively limits the rebound amplitude of the carton, reducing positional deviation during printing. Open the printing structure 16 for printing, effectively reducing the possibility of the carton itself rebounding due to material influence during the printing process, causing positional deviation and resulting in errors in the printed pattern.
