Description

Technical Field

[0001] The utility model belongs to the technical field of food packaging bag coding, in particular to a food packaging bag coding device. Background Art

[0002] Food packaging bags are soft packaging containers designed to hold, protect and carry all kinds of food. They are usually made of multi-layer composite materials, such as PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), PA (nylon) and other plastic films, as well as aluminum foil, paper, etc., which are combined together by heat sealing, bonding, etc. to form a structure with functions such as blocking oxygen, moisture, light, and microorganisms, ensuring that food remains fresh, safe, and uncontaminated during the shelf life, and providing necessary product information and marketing elements. The existing food packaging bag coding refers to the process of digitally printing on the surface of the packaging bag using a coding machine. The main purpose is to mark important product information, such as production date, batch number, shelf life, barcode, QR code, manufacturer information, ingredient list, etc. The existing food packaging bag coding equipment lacks front and rear positioning mechanisms during the process of conveying and coding on the conveying mechanism, resulting in inaccurate coding positions.

[0003] For example, the utility model with announcement number CN217918764U discloses a coding device for food packaging bags. In this patent scheme, the food packaging bags are placed on a conveying mechanism for conveying and coding. However, it lacks a front and rear positioning mechanism for the food packaging bags on the conveying mechanism. During the conveying process, the packaging bags may move slightly due to friction, wind force, uneven distribution of their own weight and other factors, resulting in the coding content not being accurately printed at the preset position, affecting the consistency and standardization of the product appearance, and may also cause the distance or angle between the printer and the surface of the packaging bag to change, affecting the uniform distribution and clarity of the inkjet. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a food packaging bag coding equipment. The positioning mechanism set can ensure that each packaging bag is stably in a predetermined position when entering the coding area, and also ensures that the inkjet printer and the surface of the packaging bag always maintain the optimal working distance and angle, which is conducive to the uniform deposition of ink droplets, making the coding characters clear and full, and the barcode and QR code scanning rate high.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a food packaging bag coding equipment, including a frame, a frame plate is arranged on the left side of the upper end of the frame, a sliding plate is slidably arranged inside the frame plate, a coding machine is arranged at the lower end of the sliding plate, an electric push rod is arranged on the upper end of the frame plate, the telescopic end of the electric push rod is connected to the upper end of the sliding plate, a conveying mechanism for conveying packaging bags is arranged inside the frame, a positioning mechanism is arranged on the front and rear sides of the frame, the conveying mechanism includes a plurality of rotating rollers rotatably arranged inside the frame, the plurality of rotating rollers are connected by a conveyor belt transmission, an electric drive unit 1 for driving the rotating rollers to rotate is arranged on the right side of the rear end of the frame, the electric drive unit 1 includes a motor arranged at the right end of the rear side of the frame, the output shaft of the motor is connected to the rear end of the rightmost rotating roller through a coupling, and the positioning mechanism includes Four sliding frames are obtained on the front and rear sides of the frame, and sliding frames are slidably arranged inside the four sliding frames, and a positioning plate is respectively arranged in front of the two adjacent sliding frames on the left and right, and a rotating seat is arranged at the lower end of the four sliding frames, and connecting frames are rotatably arranged inside the four rotating seats, and a connecting plate is arranged at the lower end of the frame, and two rotating frames are slidably arranged inside the connecting plate, and the two adjacent connecting frames on the front and rear are respectively rotatably connected to the adjacent rotating frames, and two screw rods are rotatably arranged inside the connecting plate, and the thread directions of the two screw rods are opposite, and the two rotating frames are respectively threadedly connected to the adjacent screw rods, and an electric drive unit 2 for driving the two screw rods to rotate is arranged on the bottom wall of the connecting plate, and the electric drive unit 2 includes a dual-axis motor arranged on the bottom wall of the connecting plate, and the output shafts on the left and right sides of the dual-axis motor are respectively connected to the relative inner ends of the two screw rods through couplings.

[0006] As a further improvement of the utility model, a control panel is arranged on the front side of the frame, and the motor, the dual-axis motor, the electric push rod and the inkjet printer are all electrically connected to the control panel.

[0007] As a further improvement of the present invention, support feet are respectively provided at the four corners of the lower end of the frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, the dual-axis motor is turned on through the control panel, and the output shaft rotates to drive the screw rods on both sides to rotate. Since the screw rods on both sides have opposite threads, the rotating frames on both sides approach each other, causing the internal connecting frames to rotate and gather together, thereby causing the sliding frames on the rotating seats to approach each other under the restriction of the sliding frame, and driving the positioning plates on both sides to approach each other. When the dual-axis motor is moved to the same size as the front and rear dimensions of the packaging table, the dual-axis motor is turned off, and then the food packaging bags to be coded are placed on the conveyor belt, and the food packaging bags are positioned by the positioning plates on both sides. The positioning mechanism can ensure that each packaging bag is stably in the predetermined position when entering the coding area, and also ensures that the printer always maintains the best working distance and angle with the surface of the packaging bag, which is conducive to the uniform deposition of ink droplets, making the coded characters clear and full, and the barcode and QR code scanning rate is high.

[0010] Secondly, the motor is turned on through the control panel, and the output shaft rotates to drive the rotating roller to rotate, so that the food packaging bag on the conveyor belt moves to the lower end of the inkjet printer and the motor is turned off. At the same time, the electric push rod is turned on through the control panel, and the telescopic end drives the inkjet printer on the sliding plate to move downward and contact the surface of the food packaging bag. Then, the inkjet printer is turned on through the control panel to spray code on the food packaging bag, which can quickly spray code on the food packaging bag.

[0011] Third, the electrical components on the inkjet printer can be adjusted through the control panel, making it more convenient for personnel to use.

[0012] Fourthly, the support legs can provide stable support for the inkjet coding equipment, making the operation of the inkjet coding equipment more stable. BRIEF DESCRIPTION OF THE DRAWINGS
