The food is conveyed and fed through the lifting section, achieving efficient lifting and conveying of the food. The frame shell encloses the frame to protect it, extend its service life, and ensure operator safety. A support frame supports the frame shell to ensure the integrity of the lifting and feeding sections and to provide load support for the lifting section. The other end of the support frame is connected to rollers for easy movement. The base is connected to the conveyor belt to follow its movement. A base plate is detachably connected to the base to prevent food from slipping off the lifting section. This detachable connection facilitates assembly and disassembly. The system features a movable connection between the extension plate and the base plate, allowing for the extension of the base plate and adjustment of the height to prevent food from rolling off, adapting to different food sizes without requiring replacement of the lifting device. A pair of guide side plates, arranged opposite each other on the mounting base with beveled inner walls, facilitate food guidance and positioning on the conveyor belt in the feeding section, preventing food from falling off. An extended tail plate connects to the end of the guide side plates, sealing the feeding section. The extended tail plate and the two guide side plates together form an opening for feeding. The size of the feeding opening can be adjusted by the movable extended tail plate to accommodate changes in feeding volume and facilitate docking with other equipment, making feeding more flexible. This system improves the safety of the lifting device, facilitates assembly and maintenance, provides adjustable conveying operations, and adapts to different food sizes, thus enhancing the practicality of the lifting device.

[0014] Preferably, the base has a movable groove and a positioning hole. The base plate is inserted into the movable groove, and a mounting screw is inserted into the positioning hole. The base plate has a mounting screw hole, one end of which is threaded into the mounting screw hole, and the other end of which is threaded into a fixing nut. The insert plate is inserted into the movable groove and fixed to the base by the mounting screw. The fixing nut prevents the insert plate from moving on the base, thereby stabilizing the assembled base plate to support the conveying of food. This achieves the effect of facilitating assembly, disassembly, and maintenance, and improving the structural assembly stability.

[0015] Preferably, the bottom of the movable slot is provided with a limiting slot, and the lifting extension plate is provided with an adjusting screw hole. An adjusting screw is threadedly connected to the adjusting screw hole, one end of which is connected to a limiting plate, and the other end is connected to an anti-slip component.

The movable slot is provided with a second mounting screw hole, and the first fixing screw is threadedly connected to the second mounting screw hole. The limiting plate is placed between the fixing plate and the bottom of the limiting slot. The adjusting screw is threadedly connected to the lifting extension plate, which is inserted into the movable slot and can rotate stably within the limiting slot via the limiting plate. This allows the threaded lifting extension plate to move on the adjusting screw, thereby achieving a high extension of the substrate height. The extension is highly accurate and adjustable. The first fixing screw prevents the limiting plate from moving, making the assembly and rotation of the lifting extension plate more stable and facilitating its disassembly. This achieves the effects of improving the stability and convenience of structural assembly and disassembly, and enhancing adjustability and flexibility.

[0016] Preferably, the mounting base has a mounting groove, and the guide side plate is connected to a mounting plate. The mounting plate is inserted into the mounting groove, and the mounting base is fitted with a second fixing screw. The mounting plate has a third mounting screw hole, and the second fixing screw is threaded into the third mounting screw hole.

The movable plate is rotatably connected to the upper end of the support plate, and the side end of the support plate is connected to the extension plate. The guide side plate is provided with a receiving groove, and the extension plate is inserted into the receiving groove. The movable plate in the extended tail plate is connected to the support plate and can rotate, making the movable plate an obliquely arranged inner wall plate to guide the food, adapting to the height changes of the lifting extension plate. The support plate is a vertically arranged plate structure, supported and connected by the extension plate, so that the support plate supports the rotation of the movable plate. The height of the support plate is higher than the maximum height of the lifting extension plate, so as not to affect the conveyor belt conveying. This achieves the effect of improving the structural connection stability and the smoothness of the feeding operation.

[0018] Preferably, the support plate is connected to a connecting block with a rotating hole. A fixed ring is connected to the movable plate, and a rotating shaft is inserted into the fixed ring. The rotating shaft is inserted into the rotating hole, and a limiting screw is threaded onto the end face of the rotating shaft. The movable plate rotates stably on the support plate via the rotating shaft passing through the fixed ring and the connecting block. The limiting screw prevents the rotating shaft from falling out. This improves the stability of the structural connection.

Tightening the fixing screw three merges the fixing clip and the movable plate, fixing them to the mounting base via the anti-slip plates, preventing the support plate from moving after fixing. This, in turn, fixes the size of the feed opening. The fixing nut two improves connection stability and facilitates loosening for adjustment of the extension plate position. This achieves the effect of improving the smoothness of structural operation and connection stability.

[0021] The beneficial effects of this utility model are: improved safety of the lifting device; ease of assembly and subsequent maintenance; adjustable conveying operation; adaptive adjustment to food feed volume and size, thereby improving the practicality of the lifting device; enhanced adjustability and flexibility; and improved structural operation smoothness and connection stability.
