Description

Technical Field

[0001] This utility model relates to the field of food conveying, and in particular to a vertical food lifting conveyor. Background Technology

[0002] With rising labor costs, various conveyor systems have emerged for restaurant food delivery, including horizontal conveyor chains, vertical conveyor chains, and robots. Medium-sized restaurants typically have 2-3 floors; for these, a lifting mechanism only needs to be installed at the height of each floor. For three-story structures, the kitchen can be located on the middle floor, with one vertical food conveyor installed on each of the upper and lower floors. Existing elevator shaft structures have side-opening doors, requiring the elevator to be taller than the door, resulting in a tall overall elevator shaft, occupying a large amount of space, and increasing production costs. Furthermore, position sensors and other electrical control equipment are needed to open the side door and retrieve the food upon arrival, further increasing equipment costs. Utility Model Content

[0003] The purpose of this invention is to provide a vertical food conveyor that solves the problems of existing food conveying devices occupying a large space, being inconvenient to install, and being costly.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a vertical food lifting conveyor, including a box body, a lifting machine installed inside the box body, the lifting machine including a frame, a lifting conveyor chain installed on the frame, and a food holding device that moves up and down with the lifting conveyor chain; the top of the box body is provided with an openable top cover, and the food holding device is provided with a top rod to open the top cover. When the food holding device rises to a set position, the top rod opens the top cover.

[0005] Furthermore, the frame includes a left column and a right column, with a drive shaft and a driven shaft arranged between the left column and the right column. The drive shaft is equipped with two drive gears, and the driven shaft is equipped with two driven gears. A rotary conveyor chain is arranged between each of the drive gears and the driven gears, and the two rotary conveyor chains constitute a lifting conveyor chain. The dish holding device is fixed on the two rotary conveyor chains.

[0006] To improve conveying efficiency, one dish holding device is provided on each side of the rotary conveyor chain, and they are staggered vertically. When one dish holding device is located at the uppermost set position of the rotary conveyor chain, the other is located at the lowermost designated position of the rotary conveyor chain.

[0007] Furthermore, the top cover includes a front top cover and a rear top cover, one side of which is hinged and movably mounted on the frame, and folds upward and opens under the action of the push rod.

[0008] To improve overall integrity, facilitate overall transportation and sales, and reduce subsequent installation costs, the frame also includes a bottom support frame and a top frame, and the housing is fixed on the frame.

[0009] To facilitate opening the top cover, the top rod is fixedly installed on the food serving device, and there are two of them, one on the left and one on the right.

[0010] To reduce friction with the top cover, a roller is provided at the top of the top rod.

[0011] To further improve the strength of the top rod and reduce the opening force of the top cover, the bottom of the top rod is installed close to the left or right column, and the top is tilted away from the left or right column.

[0012] The beneficial effects of this utility model are as follows: By installing a top cover on the top of the container, allowing food to be retrieved from the top, the height of the lifting machine can be effectively shortened, thereby reducing the overall cost of the equipment. The top cover automatically opens under the action of the top rod after the food holding device reaches the set height, requiring no other control equipment, thus reducing costs. When the food holding device descends, it automatically closes to prevent dust from falling in, ensuring cleanliness inside the container and demonstrating a high degree of automation. This utility model features two food holding devices that alternately rise and fall, increasing the speed of food conveying. Rollers are installed at the top of the top rod to reduce friction; simultaneously, the inclined arrangement ensures the support strength of the top rod while reducing the opening force of the top cover.

[0020] like Figures 1 to 6 As shown, a vertical food lifting conveyor includes a housing 1, a lifting mechanism 2 disposed within the housing 1, the lifting mechanism 2 including a frame 21, a lifting conveyor chain 22 disposed on the frame 21, and a food holding device 23 that moves up and down with the lifting conveyor chain 22. The top of the housing 1 is provided with an openable top cover 3, and the food holding device 23 is provided with a push rod 4 for opening the top cover 3. When the food holding device 23 rises to a set position, the push rod 4 opens the top cover 3. A loading / unloading port 11 is provided at the bottom of the housing 1 for convenient placement or removal of food from the food holding device 23. The height of the loading / unloading port 11 is set according to the convenience of a person standing to retrieve food. Typically, the loading / unloading port 11 is located on the lower level of the dining area, and the top cover 3 is located on the upper level of the dining area, enabling the transfer of food between the two levels using this vertical food lifting conveyor.

[0021] Example 1: A vertical food conveyor includes a housing 1 and a lifting machine 2 disposed inside the housing 1. A top cover 3 is provided on the top of the housing 1, and one side of the top cover 3 is rotatably mounted on the top of the housing 1 via a hinge.
