It has excellent sealing and preservation functions, ensuring that the food is fresh and does not taint the food. At the same time, it has high transparency, making it easy to observe and use. It is an ideal choice for kitchen storage and food preservation.

[0003] Generally, it is necessary to use a grinding device to grind the edge of the glass cover of the fruit and vegetable box. The existing grinding device generally uses a grinding wheel, a stable fixation and a cooling and lubrication system to achieve grinding. However, the existing grinding device cannot perform continuous operation, has low grinding efficiency, cannot adjust the grinding angle, has poor adaptability, consumes a lot of water resources during the grinding process, and cannot collect debris.

[0004] Based on this, we propose a device for grinding the edge of the glass cover of a fruit and vegetable box, which can achieve continuous operations of stable feeding, coarse grinding, fine grinding, and stable blowing and discharging. The grinding process is more stable, the grinding angle is adjustable, debris can be collected, and water circulation can be achieved. Utility Model Content

Each area of ​​the rotating mechanism is provided with a positioning mechanism 1 and a vacuum pump. An adjustable fixing mechanism is provided for rotating below the positioning mechanism 1. The coarse grinding area and the fine grinding area of ​​the rotating mechanism are both provided with a lower working mechanism. The lower working mechanism is provided with a positioning mechanism 2. The positioning mechanism 2 is provided with a grinding motor. A detachable grinding head is provided on the output shaft of the grinding motor. The discharging adjustment mechanism and the discharging conveyor are located in the discharging area of ​​the rotating mechanism. The position of the discharging adjustment mechanism is opposite to that of the discharging conveyor. The cleaning and conveying roller is located in the feeding area of ​​the rotating mechanism. The rotating mechanism is connected to a fan. The positioning mechanism 2 and the lower working mechanism are connected to a water tank. The adjustable fixing mechanism is connected to the vacuum pump at the corresponding position.

[0008] The working principle of the utility model is: adjusting the position of the adjustable fixing mechanism according to the specifications of the fruit and vegetable box cover glass, and selecting a suitable grinding head according to the grinding requirements of the edge of the fruit and vegetable box cover glass;

[0009] The cleaning conveyor roller cleans and dries the polished fruit and vegetable box cover glass and sends it to the discharge area. The positioning mechanism in the feeding area drives the adjustable fixing mechanism to move and cooperates with the vacuum pump to suck up the fruit and vegetable box cover glass.

[0010] The rotating mechanism drives the adjusting mechanism 1 to rotate intermittently 90° clockwise, thereby driving the adjustable fixing mechanism to rotate intermittently 90° clockwise, thereby driving the fruit and vegetable box cover glass to rotate intermittently 90° clockwise. At this time, the fruit and vegetable box cover glass is in the rough grinding area, and the adjusting mechanism 1 drives the adjustable fixing mechanism to descend, thereby driving the fruit and vegetable box cover glass to descend, so that the fruit and vegetable box cover glass is tightly pressed between the adjustable fixing mechanism and the lower working mechanism.

[0066] The laser detector is used to accurately locate the cover glass of the fruit and vegetable box to be polished. The adjustment mechanism 1 2 of the coarse grinding area and the fine grinding area, as well as the lower working mechanism 4 of the corresponding area, fix the cover glass of the fruit and vegetable box to be polished in the corresponding area, making the polishing process more stable. The adjustment mechanism 2 5 cooperates with the polishing motor 6 and the adjustment mechanism 1 2 to achieve two uniform polishings on all edges of the cover glass of the fruit and vegetable box, with high efficiency and good effect.

[0067] The water tank and the positioning mechanism 2 5 cooperate to cool the grinding area with water. The fan and the air outlet nozzle 104 cooperate to collect the cooling water and the debris generated during grinding. The water tank, the positioning mechanism 2 5 and the lower working mechanism 4 cooperate to realize water circulation.

[0068] Through the cooperation of the positioning mechanism 1 2, the discharging adjustment mechanism 8 and the adjustable fixing mechanism 3 in the discharging area, the polished fruit and vegetable box cover glass is smoothly and accurately delivered to facilitate the next processing step.
