Description

Technical Field

[0001] The utility model relates to the technical field of food production equipment, in particular to a coating machine with a pull-out mesh belt mechanism. Background Art

[0002] In the prior art, the food industry mainly uses coating machines to coat food bodies such as ice cream, cakes, and cereal bars with chocolate slurry, jam slurry, or syrup. The structure of a conventional coating machine generally includes a frame, a mesh belt mechanism disposed on the frame, a slurry pouring bucket, a material cylinder, a lifting pump, and a connecting pipe thereof. The mesh belt mechanism is disposed below the slurry pouring bucket, and includes a mesh belt drive roller group disposed on the frame, which includes a main mesh belt drive roller and a plurality of auxiliary mesh belt drive rollers for driving the mesh belt to circulate, and the main mesh belt drive roller is directly connected and driven by a mesh belt drive motor. The food body is transported by the mesh belt of the mesh belt mechanism and coated with slurry by the slurry pouring bucket above. The material cylinder is disposed at the lower part of the frame, and the output end of the material cylinder is connected to the slurry pouring bucket via a lifting pump and a connecting pipe.

[0003] Of course, due to the need to apply primer coating to the food raw material after top coating, most known coating machines are usually equipped with a primer mechanism on the frame corresponding to the upper slurry pouring hopper. The primer mechanism is usually arranged below the upper mesh belt of the mesh belt mechanism, and usually includes a primer trough and a primer roller arranged in the primer trough. The primer roller is driven by a primer motor to stir up the slurry and beat it to the bottom of the food raw material; and in order to realize the feeding, the output end of the material cylinder often needs to be equipped with a main conveying pipeline, and the sub-conveyor pipelines are connected to the primer mechanism (primer trough).

[0004] As we all know, after long-term production and use, the coating machine needs to be cleaned regularly to prevent the long-term adhesion and accumulation of food residues and slurry on the mesh belt from breeding bacteria and affecting the safe production of food. At the same time, in order to ensure the working reliability of the mesh belt mechanism, it also needs to be regularly inspected and maintained. However, in the structural design of the conventional coating machine mentioned above, the mesh belt mechanism is directly installed and fixed on the frame (its transmission components are often fixed by locking parts or welding) and cannot be disassembled. In addition, the upper part is interfered by components such as the slurry hopper and the bottom coating mechanism, and the lower part is interfered by the material cylinder equipment. The operating space is narrow, which makes it very inconvenient for workers to clean and inspect and maintain it.

[0005] For this reason, the industry currently has targeted designs of coating machines with detachable mesh belt mechanisms, such as the utility model patent with publication number 220897860U. In the coating machine structure disclosed therein, the mesh belt mechanism is arranged on a first movable bracket that is designed separately from the frame, and the first movable bracket is grounded with rollers, which is convenient for it to be disengaged and pulled out relative to the frame, so that the mesh belt mechanism can leave the narrow area between the upper slurry bucket and the lower material cylinder of the frame, which is very convenient for workers to perform cleaning and maintenance operations on it, which can save working hours, reduce the labor burden of workers, and improve work efficiency. In addition, in this structural design, the material cylinder is arranged on a second pull-out bracket that is designed separately from the frame, so it is also convenient to disassemble it and detach it from the frame, and then it is convenient to clean and repair it. And because the material cylinder and its second pull-out bracket can be disassembled before the frame, the interference with the rear mesh belt mechanism and its first movable bracket is reduced, which further facilitates the disengagement and pulling out of the rear mesh belt mechanism and its first movable bracket.

[0006] However, in practice, we find that the structural design of the above existing coating machine still has the following problems:

[0007] 1. When the mesh belt mechanism needs to be moved out, the entire mesh belt mechanism, including not only the related transmission mechanisms of the main and auxiliary mesh belt drive rollers, but also the mesh belt drive motor and even the attached primer motor, etc., must be moved together with the first movable bracket. In addition, the first movable bracket is set on the ground, the structure is large and cumbersome, so it is heavy and laborious for workers to operate;

[0008] 2. When removing the mesh belt mechanism and cleaning the mesh belt, main and auxiliary mesh belt drive rollers, primer trough and primer roller, it is very easy to contaminate the electrical components inside the corresponding drive motor, causing equipment damage. Summary of the invention
