Description

Technical Field

[0001] This application relates to the field of lunch box production, and particularly to a lunch box cutting device that facilitates the collection of lunch boxes. Background Art

[0002] The emergence of plastic lunch boxes has facilitated people's daily lives. Plastic lunch boxes are convenient for us to take out food and are very common in daily life. Generally, they are mainly used for takeout food packaging.

[0003] After the plastic sheet is formed into a lunch box through a lunch box vacuum thermoforming machine, it is necessary to cut the formed lunch boxes on the plastic sheet one by one to form individual lunch boxes. A common cutting method is to first cut the formed lunch boxes into sheets on the production line, and then workers cut several lunch boxes on one sheet of lunch boxes into individual lunch boxes (or place them on a cutting machine for automatic cutting). Finally, the lunch boxes are stacked. The cutting and collection of lunch boxes are time-consuming and laborious, and the work efficiency is low. Utility Model Content

[0004] In order to improve the cutting and collection efficiency of lunch boxes, this application provides a lunch box cutting device that facilitates the collection of lunch boxes.

[0005] A lunch box cutting device that facilitates the collection of lunch boxes provided by this application adopts the following technical solutions:

[0006] A lunch box cutting device that facilitates the collection of lunch boxes includes a cutting table, a cutting mechanism, and a transmission mechanism. The cutting mechanism includes a driving component arranged on the cutting table and a cutting component arranged on the cutting table. The cutting component includes a cutting plate slidably connected to the cutting table and a cutting member arranged at the bottom of the cutting plate. The cutting member includes a mounting plate, a cutting protrusion arranged on the mounting plate, and a cutting knife arranged on the mounting plate. A blanking channel is opened on the cutting table. The blanking channel is for the cutting protrusion to accommodate and is located directly below the cutting protrusion. The driving component drives the cutting plate to move vertically; a material transporting cavity is opened on the cutting table. The material transporting cavity is communicated with the blanking channel, and the material transporting cavity is located directly below the blanking channel. When the cutting protrusion pushes the lunch box down into the blanking channel, the cutting knife cuts the lunch box so that the lunch box falls from the blanking channel to the bottom wall of the material transporting cavity; the transmission mechanism includes a transmission component, a waste material conveying component, and a lunch box conveying component. The transmission component moves the lunch boxes in the material transporting cavity to the lunch box conveying component, and the waste material conveying component is used to convey the scraps.

[0007] By adopting the above technical scheme, when cutting the lunch box, an appropriate cutting piece is selected, so that the cutting protrusion and the cutting knife of the cutting piece are adapted to the lunch box, and then the mounting plate is installed on the cutting plate so that it is located directly above the feeding channel, and then the driving component drives the cutting plate to move downward so that the cutting knife cuts the lunch box, and the lunch box is cut and falls onto the bottom wall of the material transport cavity through the feeding channel, and after a part of the lunch boxes are stacked, the transmission component is started to move the lunch boxes in the material transport cavity to the lunch box transmission component to transmit the stacked lunch boxes, thereby freeing up space to collect subsequent lunch boxes, and at the same time, the waste material transmission component transmits the cut scraps to the outside of the cutting table, and collects the scraps for secondary utilization, and the cutting device can collect the lunch boxes while cutting, thereby improving the cutting and collection efficiency of the lunch boxes, and there is no need to take the finished lunch boxes to a special cutting machine for cutting and collecting the lunch boxes one by one, thereby improving the work efficiency and thus improving the production efficiency of the lunch boxes.

Finally, the transmission component 31 starts to move the lunch boxes in the material transport chamber 5 to the lunch box transfer component 33 to transfer the stacked lunch boxes, thereby freeing up space to collect subsequent lunch boxes. At the same time, the waste material transfer component 32 transfers the cut scraps to the outside of the cutting table 1, and collects the scraps for secondary utilization. The cutting device can collect lunch boxes while cutting, thereby improving the cutting and collection efficiency of the lunch boxes. There is no need to take the finished lunch boxes to a special cutting machine for cutting and collecting the lunch boxes one by one, thereby improving work efficiency and thus improving the production efficiency of the lunch boxes.
