Description

Technical Field

[0001] This utility model relates to the technical field of food box sheet cutting equipment, specifically a disposable food box edge trimming device. Background Technology

[0002] Disposable food containers are single-use food containers primarily used for takeout, fast food, and dining out. They are typically made from resin or other thermoplastic materials through thermoforming, offering advantages such as ease of processing, high production efficiency, low cost, light weight, and durability. The production process requires the use of edge-cutting devices to cut the raw materials into sheets, commonly available in round, square, and rectangular shapes.

[0003] A search revealed that patent application CN202122243054.9 discloses a sheet trimming device for disposable lunch box production. Its operation is continuous, eliminating the need for manual sheet feeding, reducing manual labor, and improving the efficiency of lunch box sheet cutting. It includes a frame, two sets of rotating roller conveyor mechanisms, a servo motor, a synchronous belt, a first pneumatic cylinder, a cutting die, a second pneumatic cylinder, a feeding platen, and a tail material winding mechanism. The two sets of rotating roller conveyor mechanisms are respectively installed on the left and right sides of the frame. The servo motor is fixedly installed on the frame, and its output end is synchronously connected to the two sets of rotating roller conveyor mechanisms via the synchronous belt. Each set of rotating roller conveyor mechanisms includes two sets of conveying rollers and two sets of gears. Both sets of conveying rollers can be rotatably mounted on the frame. The feeding platen is fixedly installed at the output end of the second pneumatic cylinder. The tail material winding mechanism is installed on the left side of the frame. A cutting blade is provided at the bottom of the cutting die, and the cutting blade has multiple cutting edges.

[0004] However, this patent has its shortcomings. The cutting die and the pressing plate in this sheet trimming device are fixed in shape and cannot be adjusted. Therefore, it cannot meet the cutting needs of different shaped lunch box sheets. The applicability of the equipment is poor. In addition, during the cutting process, the cut lunch box sheets are easy to get stuck in the cutting die and cannot fall out smoothly, which affects the unloading of the material after cutting.

[0005] To address this, we propose a disposable lunchbox trimming device. Utility Model Content

The ends of the two springs 8 away from the extrusion plates 22 are fixedly installed on the first adjusting seat 9. A second adjusting seat 16 is rotatably connected inside the machine base 1, directly below the first adjusting seat 9. Multiple mold grooves 11 of different shapes are provided on the outer side of the second adjusting seat 16.

[0026] Two conveying rollers 4 are rotatably connected to the right side of the second adjusting seat 16 inside the base 1. The rear ends of both conveying rollers 4 extend out of the base 1 and are fixedly mounted with gears 5. The two gears 5 are meshed together. The conveying rollers 4 facilitate the conveying of raw materials for cutting lunch boxes. A first motor 7 is fixedly mounted at the front end of the base 1. The output end of the first motor 7 is fixedly mounted on one of the conveying rollers 4. This design is beneficial for the use of this equipment. A PLC controller 6 is fixedly mounted at the left side of the first motor 7 at the front end of the base 1. The PLC controller 6 facilitates the control of this equipment. Limit seats 14 are fixedly mounted at both the front and rear ends of the U-shaped frame 18. Limit grooves 15 are provided at both the front and rear ends of the mounting frame 2. The limit seats 14 are slidably connected in the limit grooves 15. The limit seats 14 can limit the movement of the U-shaped frame 18. A third motor 13 is fixedly mounted at the lower part of the limit seats 14 at the rear end of the U-shaped frame 18. The output end of the device is fixedly installed on the first adjusting seat 9. The first adjusting seat 9 is rotated by the third motor 13, which is beneficial to the use of this device. The second motor 10 is fixedly installed at the rear end of the base 1 below the third motor 13. The output end of the second motor 10 is fixedly installed on the second adjusting seat 16. The second adjusting seat 16 is rotated by the second motor 10, which is beneficial to the use of this device. The take-up roller 3 is rotatably connected to the left side of the mounting frame 2 inside the base 1. The fourth motor 25 is fixedly installed at the front end of the base 1 corresponding to the take-up roller 3. The output end of the fourth motor 25 is fixedly installed on the take-up roller 3. The take-up roller 3 is rotated by the fourth motor 25, which is beneficial to the use of this device. The guide plate 20 is fixedly installed at the left side of the second adjusting seat 16 inside the base 1. The collection box 19 is inserted into the left side of the guide plate 20 inside the base 1. The guide plate 20 facilitates the flow of the cut lunch box sheet into the collection box 19.

[0027] Working Principle: During use, place the lunchbox material between two conveyor rollers 4 and turn on the cutting switch. The first motor 7 drives the conveyor rollers 4 to rotate. Since the two conveyor rollers 4 are connected by two meshing gears 5, they rotate in opposite directions, thus conveying the lunchbox material to the left. When the lunchbox material passes the second adjusting seat 16, two cylinders 17 drive the U-shaped frame 18 to press down, causing multiple cutting molds 12 to insert into multiple corresponding mold slots 11. During the pressing process, due to the thickness of the die-cutting material, the stripper plate 24 retracts into the cutting mold 12, thereby cutting out multiple lunchbox sheets. After cutting, cylinders 17 drive the U-shaped frame 18 to rise and reset. At this time, the spring 8 rebounds, causing the extrusion plate 22 to reset. The extrusion plate 22 then drives the push rod 23 and the stripper plate 24 to reset, thus ejecting the cut lunchbox sheets from the cutting mold 12. As the lunchbox material continues to be conveyed to the left, the cut lunchbox sheets will pass through the guide... The flow plate 20 slides into the collection box 19, where the right end of the cut lunch box material can be wound around the take-up roller 3. The fourth motor 25 drives the take-up roller 3 to rotate, thus taking in the waste material. When it is necessary to cut lunch box sheets of other shapes, the switches of the second motor 10 and the third motor 13 can be turned on. At this time, the second motor 10 drives the second adjusting seat 16 to rotate 90 degrees clockwise, and the third motor 13 drives the first adjusting seat 9 to rotate 90 degrees clockwise. This allows the cutting die frame 12 and the die groove 11 of different shapes to correspond, so that other shapes of lunch box sheets can be cut using the above principle. This disposable lunch box edge trimming device is easy to use. The above components can be adjusted according to the use to meet the die cutting needs of different shapes of lunch box sheets, thereby further improving the applicability of this equipment. At the same time, after each cut, the lunch box sheet in the cutting die frame 12 can be automatically ejected for easy unloading, thereby further improving the convenience of using this equipment.

[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.
