Description

Technical Field

[0001] This application relates to the technical field of food packaging bag processing, and in particular to a food packaging bag film printing device. Background Technology

[0002] Food packaging bag film printing equipment is a type of machinery specifically designed for printing patterns, text, and logos on various film materials used in food packaging bags. Its main purpose is to accurately, clearly, and persistently print various information on food packaging bag films. This information includes not only basic product information such as the food's name, brand logo, ingredient list, production date, and shelf life, but also aesthetically pleasing patterns and promotional information. This satisfies consumers' need to understand food-related information and also attracts consumers and enhances the product image.

[0003] A search revealed Chinese patent application CN202221097437.8, which discloses a film printing device for food packaging bags. The device includes a film printing preparation body, a printing machine, a motor mechanism, and an ice crystal plate. A first rotating cylinder is rotatably connected inside the film printing preparation body, and a second rotating cylinder is also installed inside. A connecting block is fixedly connected to the top of the film printing preparation body, and a connecting box is fixedly connected to the top of the connecting block. A flip plate is hinged to the surface of the connecting box. This invention, through the motor mechanism, allows the packaging bag to be printed via a channel printing machine during movement. The motor mechanism drives a rotating rod and fan blades to generate airflow. The ice crystal plate lowers the temperature of the air inside the connecting box, and the exhaust pipe discharges cold air onto the surface of the packaging bag through the exhaust port. This allows the ink on the packaging bag surface to cool and dry quickly, thus avoiding the need for prolonged drying after printing.

[0004] Regarding the aforementioned technologies, the inventors discovered the following defects: During the printing process, the packaging bag may be wrinkled due to compression while being placed on the roller. These wrinkles cause unevenness on the surface of the packaging bag, resulting in changes in the distance between the inkjet printer nozzle and the surface of the packaging bag at the wrinkles during the subsequent coding process. This leads to uneven ink adhesion on the packaging bag, resulting in blurred, broken, or missed coding characters, which affects the accurate transmission of product information.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a food packaging bag film printing device. For example... Figure 1-4 As shown, the device includes a base plate 1, a material handling assembly 2 on the upper side of the base plate 1, a square frame 3 on the upper side of the base plate 1 and located on one side of the material handling assembly 2, a rotating shaft 4 rotatably fitted to one side of the inner wall of the square frame 3, a measuring roller 5 fixedly connected to the rotating shaft 4, a mounting frame 6 fixedly connected to one side of the square frame 3, an encoder 7 cooperating with the rotating shaft 4 fixedly connected to one side of the inner wall of the mounting frame 6, and a processor 8 cooperating with the encoder 7 fixedly connected to one side of the square frame 3. The formula between the processor 8 and the encoder 7 is the number of pulses divided by the pulse resolution and then multiplied by the circumference of the measuring roller 5, which is existing technology and will not be elaborated further.

[0024] Please see Figure 1 The material placement assembly 2 includes a placement frame 201 fixedly connected to the upper side of the base plate 1, placement grooves 202 opened on both sides of the inner wall of the placement frame 201, and a raw material roller 203 set on the inner wall of the placement groove 202. 203 can be a winding roller for storing food packaging bag grinding material. By placing 203 into the placement groove 202, 203 can be supported.

[0025] Please see Figure 3 A rubber ring 15 is fixedly connected to the outer side of the measuring roller 5. Multiple anti-slip grooves are provided on the rubber ring 15. When the material is compressed and comes into contact with the measuring roller 5, the rubber ring 15 can be placed between the material to increase the friction between the material and the material, so that the measuring roller 5 can be better rotated when the material moves.

[0026] A lower clamping plate 9 is fixedly connected to the upper side of the base plate 1 and to one side of the mounting frame 6. A heating component 10 is provided on the upper side of the lower clamping plate 9. An extrusion component 11 is provided on the upper side of the inner wall of the square frame 3. A printing machine 12 and a winding device 16 are respectively provided on the upper side of the base plate 1 and away from the lower clamping plate 9. The winding device 16 can be driven by a motor and is used to wind up one end of the packaging bag.

[0027] Please see Figure 2 The heating component 10 includes a hidden groove 101 opened on the upper side of the lower clamping plate 9 and a heating plate 102 fixedly connected to the inner wall of the hidden groove 101. The heating plate 102 heats the material to a certain temperature. When the material comes into contact with the heating plate 102, it can be softened by the temperature. Then, another rubber ring 15 generates a moving pulling force, which can flatten the wrinkled parts of the material.

[0028] Please see Figure 2 The extrusion assembly 11 includes an electric push rod 111 fixedly connected to the upper side of the inner wall of the square frame 3, a U-shaped frame 112 fixedly connected to the output end of the electric push rod 111, and a lower pressure roller 113 fixedly connected to the inner wall of the U-shaped frame 112. The lower pressure roller 113 cooperates with the measuring roller 5. By activating the electric push rod 111 to press down 1112, the lower pressure roller 113 can extrude material on the lower side, so that the material adheres to the rubber ring 15.

[0029] Please see Figure 2 and Figure 3 The extrusion assembly 11 also includes an extension plate 114 fixedly connected to one side of the U-shaped frame 112, two springs 115 fixedly connected to the lower side of the extension plate 114, and an upper clamping plate 116 fixedly connected to the lower end of the two springs 115. When the electric push rod 111 is pressed down, the extension plate 114 moves accordingly, and the springs 115 can hold the lower clamping plate 9 together to a certain extent, thus clamping the food bag packaging bag.

[0030] Please see Figure 2The upper side of the extension plate 114 is provided with a guide opening 13, and the upper side of the upper clamping plate 116 is fixedly connected with a guide rod 14 that slides in the guide opening 13. When the upper clamping plate 116 moves, the guide rod 14 can slide in the guide opening 13, which facilitates the limiting of the upper clamping plate 116 and avoids tilting.

[0031] The implementation principle of the food packaging bag film printing equipment in this application embodiment is as follows: When in use, 203 is placed inside the placement groove 202, and then one end of the packaging bag is passed between the lower pressure roller 113 and the measuring roller 5 and between the lower clamping plate 9 and the upper clamping plate 116, and the other end is connected to the winding device 16. Then, the lower electric push rod 111 drives the U-shaped frame 112 and the lower pressure roller 113 to move downward, so that the packaging bag is in contact with the outer side of the measuring roller 5. When the packaging bag is moved, the measuring roller 5 will rotate and transmit the data to the encoder 7. The encoder 7 transmits the detected number of turns to the processor 8 to calculate the printing length of the packaging bag, which is convenient for users to statistically analyze the production data.

[0032] When the electric push rod 111 pushes the U-shaped frame 112 downward, the upper clamping plate 116 moves downward simultaneously, squeezing the food packaging bag downward. Then, the heating plate 102 in the hidden groove 101 is activated to heat the corresponding temperature. The other end pulls the plastic bag straight through the winding device 16. The heating makes the packaging bag material soft, thereby gradually stretching and unfolding the wrinkles to achieve a smoothing effect. This ensures that the printed patterns and text are clear and complete, improving the visual effect and quality of the printed matter.

[0033] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
