Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to an oil-proof paper bag pattern printing press. Background Technology

[0002] As a specialized piece of equipment, the core function of the greaseproof paper bag pattern printing machine is to accurately print specific patterns, text, or colors onto the surface of greaseproof paper bags, aiming to meet the personalized needs of commercial operations, industrial production, and consumers. This equipment integrates high-precision printing technology, ensuring that every detail is clearly presented. Simultaneously, its stable mechanical structure provides a solid foundation for continuous and efficient production. Existing printing machines have shortcomings in paper bag position detection, lacking an effective detection structure. When the paper bag's position deviates, it directly affects the accuracy of the printing position, leading to a decline in printing quality. Existing technologies, represented by (Publication No. CN220639225U), utilize a printing machine with a smoothing mechanism. First, the paper bag is placed on the second roller. Then, motor one is activated, causing the first roller to descend and press the paper bag firmly. Motor two is then activated, causing the second roller to rotate and flatten the paper bag. This effectively prevents the paper bag from being wrinkled during printing, thus affecting the printing effect. Furthermore, the design of the heat drying device dries the ink printed on the paper bag, preventing the printed pattern from being smudged during packaging. This effectively solves the problems of existing technologies. However, its structure still needs improvement, specifically as follows:

[0003] In this solution, when the printing press prints on the greaseproof paper bag, the first starting motor descends to press the paper bag tightly, and then the second starting motor drives the second roller to rotate and flatten the paper bag. However, if there are wrinkles in the paper bag before printing, the wrinkles will fold up after pressing and rotating, which will affect the subsequent printing quality. There is no suitable stretching structure to flatten the paper bag. Therefore, a greaseproof paper bag pattern printing machine is needed to improve the above problems. Utility Model Content

[0004] To address the problem that printing presses lack a suitable stretching structure to flatten oil-proof paper bags during printing, this invention provides an oil-proof paper bag pattern printing machine to solve the aforementioned issues.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An oil-proof paper bag pattern printing machine includes a mounting frame, a mounting plate disposed on the opposite outer wall of the mounting frame, a control panel disposed on the side wall of the mounting plate, a flattening assembly disposed on the outer wall of the mounting plate, a conveyor disposed on the inner wall of the mounting frame, a rotating base disposed on the base surface of the conveyor, a high-definition image sensor disposed directly above the conveyor and on the outer wall of the mounting plate, a mounting bracket disposed on the outer wall of the mounting frame, an electrically controlled lifting mechanism disposed on the inner wall of the mounting bracket, wherein a printing bracket is mounted on one end of the electrically controlled lifting mechanism via a fixed rod, and the printing bracket and the fixed rod are connected by a rotatable connection, and a printing plate is disposed on the inner wall of the printing bracket.

[0007] As a preferred embodiment of this utility model, the leveling component includes an electrically controlled cylinder, which is mounted on the inner wall of the mounting plate, and a mounting base is mounted on one end of the electrically controlled cylinder.

[0008] As a preferred embodiment of this utility model, a rotating shaft is provided on the outer wall opposite to the mounting base, and a connecting plate is rotatably connected to the outer wall of the rotating shaft.

[0009] As a preferred embodiment of this utility model, one end of the connecting plate is rotatably connected to a rotating shaft, one end of the rotating shaft is mounted with a fixed base, and a rotating rod is rotatably connected to the outer wall of the fixed base.

[0010] As a preferred embodiment of this utility model, a flattening roller is rotatably connected to the outer wall of the rotating rod, and a limit spring is provided on the outer wall of the fixed base, with one end of the limit spring connected to the outer wall of the mounting base.

[0011] As a preferred embodiment of this utility model, the electronically controlled cylinder is tilted downward at 45 degrees relative to the top plane of the mounting plate, multiple sets of the limiting springs are arranged in an array from left to right and are respectively located on the outer wall of the mounting base, and foot pads are provided at the bottom corner of the mounting frame, and the foot pads are rectangular in structure.

[0012] As a preferred embodiment of this utility model, the control panel is connected to a high-definition image sensor, a conveyor, an electric lift, a rotating base, and an electric cylinder via wires, and the connection method is electrical connection. Multiple sets of high-definition image sensors are provided and are located on the outer wall of the mounting plate.

[0013] As a preferred embodiment of this utility model, the high-definition image sensor is located on one side of the rotating base, the electrically controlled lifting mechanism is provided in multiple sets and is located on the inner wall of the mounting bracket, and the flattening roller is located directly above the rotating base.

[0014] Compared with existing technologies, this utility model enables the paper bag to be stretched and flattened to both sides by setting a flattening component in the oil-proof paper bag pattern printing machine. When the rotating base moves the paper bag to the appropriate position, the fixed base applies downward pressure to the flattening roller through the rotating rod, causing the flattening roller to press against the paper bag. Subsequently, the electric control cylinder moves in the opposite direction, causing the flattening roller to move to both sides, thereby stretching the paper bag from both sides, flattening the surface wrinkles of the paper bag. Then, the electric control lifting machine drives the printing plate to print on the paper bag through the printing bracket, thus solving the problem that the wrinkles and folds of the paper bag will affect the subsequent printing quality and that there is no suitable stretching structure to flatten the paper bag.

[0015] This invention utilizes a high-definition image sensor and a rotating base in an oil-proof paper bag pattern printing machine to adjust the position of the paper bag. The high-definition image sensor generates an electrical signal, which is transmitted to the control panel via wires. This causes the control panel to rotate the rotating base, moving the paper bag to the appropriate position. When the operator presses the stop switch on the control panel, the rotating base stops the paper bag in the correct position. Furthermore, the high-definition image sensor and the rotating base work together to automatically adjust the position of the paper bag, thus solving the problem that deviations in the paper bag's position directly affect the accuracy of the printing position, leading to a decrease in printing quality.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figure 1-5 The illustrated oil-proof paper bag pattern printing machine includes a mounting frame 1, a mounting plate 2 disposed on the opposite outer wall of the mounting frame 1, a control panel 3 disposed on the side wall of the mounting plate 2, a flattening assembly 4 disposed on the outer wall of the mounting plate 2, a conveyor 5 disposed on the inner wall of the mounting frame 1, a rotating base 6 disposed on the base surface of the conveyor 5, a high-definition image sensor 7 disposed directly above the conveyor 5 and on the outer wall of the mounting plate 2, a mounting bracket 8 disposed on the outer wall of the mounting frame 1, an electrically controlled lifting mechanism 9 disposed on the inner wall of the mounting bracket 8, wherein a printing bracket 11 is mounted on one end of the electrically controlled lifting mechanism 9 via a fixing rod 10, and the printing bracket 11 and the fixing rod 10 are connected by a rotatable connection, and a printing plate 12 is disposed on the inner wall of the printing bracket 11.

[0024] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The leveling component 4 includes an electrically controlled cylinder 401, which is mounted on the inner wall of the mounting plate 2. One end of the electrically controlled cylinder 401 is mounted on a mounting base 402. A rotating shaft 403 is provided on the outer wall of the mounting base 402. A connecting plate 404 is rotatably connected to the outer wall of the rotating shaft 403. A rotating shaft 405 is rotatably connected to one end of the connecting plate 404. A fixed base 406 is mounted on one end of the rotating shaft 405. A rotating rod 407 is rotatably connected to the outer wall of the fixed base 406. A leveling roller 408 is rotatably connected to the outer wall of the rotating rod 407. The leveling roller 408 is located directly above the rotating base 6. A limit spring 409 is provided on the outer wall of the fixed base 406. One end of the limit spring 409 is connected to the outer wall of the mounting base 402.

[0025] Among them, the electric cylinder 401 is tilted downward at 45 degrees relative to the top plane of the mounting plate 2. Multiple sets of limit springs 409 are arranged in an array from left to right and are located on the outer wall of the mounting base 402. Foot pads 13 are provided at the bottom corner of the mounting bracket 1, and the foot pads 13 are rectangular in structure. The control panel 3 is connected to the high-definition image sensor 7, the conveyor 5, the electric lift 9, the rotating base 6 and the electric cylinder 401 through wires. Under the action of the electric connection, the device is powered on, and the control panel 3 drives the high-definition image sensor 7, the conveyor 5, the electric lift 9, the rotating base 6 and the electric cylinder 401 to operate. Multiple sets of high-definition image sensors 7 are arranged and are located on the outer wall of the mounting plate 2. The high-definition image sensor 7 is located on one side of the rotating base 6. Multiple sets of electric lift 9 are arranged and are located on the inner wall of the mounting bracket 8.

[0026] In operation, the oil-proof paper bag pattern printing machine of this solution utilizes a conveyor 5 mounted on the inner wall of the mounting frame 1. A rotating base 6 is positioned on the base of the conveyor 5. A high-definition image sensor 7 is mounted directly above the conveyor 5 and on the outer wall of the mounting plate 2. When the conveyor 5 drives the rotating base 6, it causes the paper bag to move laterally to the appropriate position. Subsequently, the high-definition image sensor 7 detects the position of the paper bag and generates an electrical signal, which is transmitted through wires to the control panel 3. This causes the control panel 3 to control the rotating base 6 to rotate. When the appropriate position is reached, the operator presses the stop switch on the control panel 3, stopping the rotating base 6 and the paper bag in the correct position. Furthermore, the high-definition image sensor 7 and the rotating base 6 work together to automatically adjust the position of the paper bag, thus solving the problem that deviations in the paper bag position directly affect the accuracy of the printing position, leading to a decrease in printing quality.

[0027] An electrically controlled cylinder 401 is mounted on the inner wall of the mounting plate 2. One end of the cylinder 401 is fitted with a mounting base 402. A rotating shaft 403 is located on the opposite outer wall of the mounting base 402. With the flattening roller 408 positioned directly above the rotating base 6, when the rotating base 6 moves the paper bag to a suitable position, the control panel 3 controls the electrically controlled cylinder 401 to operate. One end of the cylinder 401 applies a thrust to the mounting base 402, causing it to move to the appropriate position. This presses the flattening roller 408 in the flattening assembly 4 against the outer wall of the paper bag. A rotating rod 407 is rotatably connected to the outer wall of the fixed base 406, and the flattening roller 408 is rotatably connected to the outer wall of the rotating rod 407. The outer wall of the fixed base 406 is equipped with... A limiting spring 409 is provided, with one end of the limiting spring 409 connected to the outer wall of the mounting base 402. Under the action of the limiting spring 409, the limiting spring 409 applies a pushing force to the fixed base 406, causing the fixed base 406 to apply downward pressure to the flattening roller 408 through the rotating rod 407. This causes the flattening roller 408 to press against the paper bag. Subsequently, the electric control cylinder 401 moves in the opposite direction, causing the flattening roller 408 to move to both sides. This causes the flattening roller 408 to stretch the paper bag from both sides, flattening the wrinkles on the surface of the paper bag. Then, the electric control lifting machine 9 drives the printing plate 12 to print on the paper bag through the printing bracket 11. This solves the problem that the wrinkles and folds of the paper bag affect the subsequent printing quality, and that there is no suitable stretching structure to flatten the paper bag.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
