Description

Technical Field

[0001] This utility model relates to the field of food packaging bag technology, specifically a food packaging bag printing and cutting device. Background Technology

[0002] Food packaging bags are an important material used for packaging and protecting food. Their main functions are to prevent food contamination, maintain food freshness, extend shelf life, and provide necessary information and convenience. With increasing environmental awareness, many manufacturers have begun to focus on the environmentally friendly design of food packaging bags, using renewable and biodegradable materials to contribute to reducing plastic pollution. Food packaging bags not only play an important role in protecting food but also involve multiple functions such as aesthetics, practicality, and environmental protection, making them an indispensable part of the food industry. However, existing food packaging bag printing and cutting devices still have certain shortcomings. While traditional food packaging bag printing and cutting devices can be used well, they cannot perform fully automatic printing on raw materials and still require manual operation. Furthermore, they cannot print intermittently on raw materials. When cutting raw materials, they cannot buffer the pressure of the cutting blade, which can easily damage the workbench and conveyor belt surface. Excessive cutting force over a long period of time can affect the normal operation of the equipment, often causing problems for users. Utility Model Content

The fixed rod, the first spring, the second spring, and the sliding rod are symmetrically arranged about the center of the first frame.

[0007] As a preferred technical solution of this utility model, a connecting seat is fixedly installed on the left side of the top surface of the base plate, and a drive shaft is connected to the front wall of the connecting seat through a bearing. Two spur gears are evenly fixedly installed through the drive shaft, and a conveyor belt meshes with the outside of the spur gears.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This food packaging bag printing and cutting device places the raw material on a conveyor belt, starts the transmission motor to rotate and drive the spur gear to rotate, and drives the conveyor belt and raw material to move through the meshing of the spur gear and the conveyor belt. The rotating turntable drives the first connecting rod to rotate, thereby driving the semi-circular gear to rotate. Through the meshing of the semi-circular gear and the rack, the rack moves up and down, so that the printing device prints the raw material intermittently. After printing is completed, the electric push rod is activated to drive the second connecting plate and the cutting blade to move downward to cut the raw material. At the same time as cutting, the second spring buffers the cutting blade, which improves the printing and cutting efficiency of the raw material, reduces the labor burden of the user, and can buffer the downward force of the cutting blade during cutting to prevent damage to the conveyor belt.

[0019] A slide rod 12 is fixedly installed on the left side of the upper top surface of the second connecting plate 7. The upper top surface of the slide rod 12 is fixedly installed on the inner top surface of the first frame 2, and the slide rod 12 is slidably connected to the upper top surface of the first connecting plate 4. The fixed rod 5, the first spring 6, the second spring 10 and the slide rod 12 are symmetrically arranged about the center of the first frame 2.

[0020] A connecting seat 13 is fixedly installed on the left side of the top surface of the base plate 1. A drive shaft 14 is connected to the front wall of the connecting seat 13 by a through bearing. Two spur gears 15 are evenly fixedly installed on the drive shaft 14. A conveyor belt 16 meshes with the outside of the spur gears 15. A drive motor 17 is fixedly installed on the upper end of the rear wall of the connecting seat 13.

[0021] The front wall of the drive motor 17 is fixedly installed on the rear wall of the drive shaft 14. The connecting seat 13 and the spur gear 15 are symmetrically arranged about the center of the conveyor belt 16. The second frame 18 is fixedly installed on the left side of the top surface of the base plate 1. The limit block 19 is fixedly installed on the top surface of the second frame 18. The left side of the limit block 19 is slidably connected to the rack 20. The left side of the rack 20 is meshed with the semi-circular gear 21.

[0022] A rotating rod 22 is fixedly installed through the left side of the front wall of the semi-circular gear 21, and the rotating rod 22 is connected to the second frame 18 by a bearing.

[0023] Working Principle: When using a food packaging bag printing and cutting device, the user first places the raw material on the conveyor belt 16, starts the drive motor 17 to rotate, which drives the drive shaft 14 to rotate. The rotation of the drive shaft 14 drives the spur gear 15 to rotate. The meshing of the spur gear 15 with the conveyor belt 16 moves the conveyor belt 16, thereby moving the raw material. The turntable 25 is manually rotated to drive the second connecting rod 24 to rotate. The rotation of the second connecting rod 24 drives the first connecting rod 23 to rotate, which in turn drives the semi-circular gear 21 to rotate. The meshing of the semi-circular gear 21 with the rack 20 moves the rack 20 up and down, so that the printing device 26 intermittently prints on the raw material. After printing is completed, the electric push rod 3 is activated to move the first connecting plate 4 downward, which presses down the first spring 6, thereby moving the second connecting plate 7 and the cutting blade 9 downward to cut the raw material. During the cutting, the second spring 10 buffers the cutting blade 9, thus completing a series of operations. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
