Description

Technical Field

[0001] This utility model relates to the field of mooncake production, and in particular to a conveying device for mooncake production. Background Technology

[0002] In mooncake production, after the ingredients are filled and molded, the dough needs to be brushed with oil and baked in an oven. Hot air in the oven ensures even heating of all the dough pieces, resulting in the final mooncake product. Traditionally, this involves brushing the oil by hand and placing the mooncakes on trays in the oven.

[0003] Currently, some equipment uses conveyor belts to feed mooncakes into the oven, with brushes placed above the conveyor belt to brush oil onto the passing mooncakes. While this method is cheaper than manual oiling, it only allows oiling the top and sides of the mooncakes, not the bottom. Furthermore, because the mooncakes are not turned during baking, the top and bottom surfaces bake unevenly, resulting in significant differences in texture and taste. Additionally, although a spatula-like structure can flip the mooncake dough, the required speed is relatively fast, and the significant vibration during flipping can easily break the outer crust, affecting its appearance. Utility Model Content

[0004] The purpose of this invention is to provide a conveying device for mooncake production, which can automatically flip the mooncakes while brushing oil on both sides, and ensure that the taste of the top and bottom surfaces of the mooncakes is basically the same after baking.

[0005] To achieve the above objectives, this utility model provides a conveying device for mooncake production, including conveyor belts, the number of which is at least three layers arranged from top to bottom, each conveyor belt having a matching roller at its end, a flipping structure that allows the mooncakes to flip between the output end of the upper conveyor belt and the input end of the lower conveyor belt, and an oiling structure for brushing oil onto the surface of the mooncakes on the flipping structure.

[0006] As a further improvement of this utility model, the flipping structure includes a housing, and one side of the housing has a concave arc-shaped surface on its outer side. The concave arc-shaped surface is located on the outer side of the roller at the output end of the conveyor belt, and there is a space between the two for the mooncake to pass through.

[0007] As a further improvement of this utility model, the brushing structure includes a brush disposed on the entire outer surface of the concave arc surface, with the top of the brush facing the roller at the output end of the conveyor belt; the brushing structure also includes an oil distribution chamber disposed on the inner side of the concave arc surface, the oil distribution chamber being connected to multiple oil outlets, the oil outlet ends of the oil outlets extending to the outer surface of the concave arc surface, and each oil outlet being distributed at the bottom of the brush.

[0008] As a further improvement of this utility model, the oil outlet is located on the upper section of the concave arc surface and above the roller.

[0009] As a further improvement of this utility model, the housing is provided with a gas pressure stabilizing chamber, which is connected to an air inlet pipe and multiple air outlets. The air outlets protrude from the outer surface of the concave arc-shaped surface, and the multiple air outlets are distributed at the bottom of the brush, with the air outlets facing the roller.

[0010] As a further improvement of this utility model, it also includes an arc-shaped bracket, the outer side of which is fitted with the outer surface of the concave arc-shaped surface; the arc-shaped bracket includes multiple horizontally arranged horizontal bars, and also includes an arc-shaped strip connected to the multiple horizontal bars; the bottom of the brush is connected to the horizontal bars, and adjacent horizontal bars form a strip-shaped relief groove, one end of which is open; the oil nozzle and the air nozzle are located inside the relief groove.

[0011] As a further improvement of this utility model, a feeding plate is connected to the lower end of the concave arc surface, and the feeding plate is located above the input end of the lower conveyor belt.

[0012] Beneficial effects

[0013] Compared with the prior art, the advantages of the conveying device for mooncake production of this utility model are:

[0014] 1. The conveyor device is installed inside the oven. During the process of transferring the mooncake from the upper conveyor belt to the lower conveyor belt, the flipping structure can be used to flip the mooncake. At the same time, the oiling structure can be used to brush oil on the surface and sides of the mooncake that were originally facing up. After baking, it can ensure that the upper and lower surfaces of the mooncake have a basically consistent taste.

[0015] 2. The space formed by the concave arc surface and the roller guides the mooncake to be turned over. No additional drive mechanism is needed when turning the mooncake. The structure is simple, the energy consumption is low, and it can be easily implemented in the oven.

[0016] 3. The brushes are positioned across the entire outer surface of the concave arc surface. This not only cushions the mooncakes during flipping, reducing the risk of the crust breaking, but also allows oil seeping from the oil outlet to fall onto the brushes, ensuring even oiling as the mooncake passes over them. The oil outlet is located on the upper section of the concave arc surface and above the roller, allowing the oil to flow downwards under its own weight and contact all the brushes, reducing oil waste and improving the evenness of oil application.

[0017] 4. When there is too much oil on the brush, the bristles will stick together. Additionally, as mooncakes pass by, the bristles will deflect towards the lower end of the concave arc surface, preventing them from returning to their original position and facing the roller. This means they cannot effectively cushion subsequent mooncakes. Therefore, the air outlet should always be blowing air to allow the bristles to return to their original position as much as possible after applying oil to the mooncakes, ensuring a cushioning effect and extending the brush's lifespan.

[0018] 5. When the brush needs to be replaced, since the brush is fixed on the arc-shaped bracket, the brush can be replaced by pulling the arc-shaped bracket outward from the concave arc surface. When installing the arc-shaped bracket, insert it from one end of the concave arc surface, so that both the oil nozzle and the air nozzle pass through the relief groove of the arc-shaped bracket to avoid interference.

[0025] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] Example

[0027] The specific embodiments of this utility model are as follows: Figures 1 to 4As shown, a conveyor device for mooncake production includes conveyor belts 1 arranged in at least three layers from top to bottom. Each conveyor belt 1 has a roller 11 at its end. A flipping structure is provided between the output end of the upper conveyor belt 1 and the input end of the lower conveyor belt 1 to allow mooncakes 8 to flip. The flipping structure is also equipped with an oiling structure for brushing oil onto the surface of the mooncakes 8. The conveying directions of adjacent upper and lower conveyor belts 1 are opposite. One roller 11 of each conveyor belt 1 is linked to a drive motor. To allow the conveyor belts 1 to be placed inside an oven, they can be made of heat-resistant materials, such as metal conveyor belts.

[0028] The flipping structure includes a housing 2, and a concave arc surface 21 is provided on the outer side of one side of the housing 2. The concave arc surface 21 is located outside the roller 11 at the output end of the conveyor belt 1, and there is a space between them for the mooncake 8 to pass through.

[0029] The oiling structure includes a brush 3 covering the entire outer surface of the concave arc-shaped surface 21, with the top of the brush 3 facing the roller 11 at the output end of the conveyor belt 1. The oiling structure also includes an oil-distributing chamber 4 located inside the concave arc-shaped surface 21. The oil-distributing chamber 4 is connected to multiple oil outlets 41, with the oil outlet ends of the outlets extending to the outer surface of the concave arc-shaped surface 21. Each oil outlet 41 is located at the bottom of the brush 3. The oil-distributing chamber 4 is connected to an oil inlet pipe (not shown in the figure), which is connected to a peristaltic pump. The peristaltic pump pressurizes the oil, causing the edible oil in the oil-distributing chamber 4 to seep out through the oil outlets 41. The width of the brush 3 is greater than the width of the mooncake 8, ensuring that both the originally upward-facing surface and the sides of the mooncake 8 are oiled when the mooncake 8 passes over the brush 3 and is flipped.

[0030] Specifically, the oil outlet 41 is located on the upper section of the concave arc surface 21 and above the roller 11.

[0031] The housing 2 contains a gas pressure regulating chamber 5, which is connected to an air inlet pipe 52 and multiple air outlets 51. The air outlets 51 protrude from the outer surface of the concave arc-shaped surface 21. The multiple air outlets 51 are distributed at the bottom of the brush 3, and the air outlets 51 face the roller 11. The air outlets 51 are arranged in multiple rows, and the arrangement direction of each row of air outlets 51 is parallel to each other.

[0032] The device also includes an arc-shaped support 7, the outer side of which fits into the outer surface of the concave arc-shaped surface 21. The arc-shaped support 7 includes multiple horizontally arranged crossbars 71, and arc-shaped strips 73 connected to the crossbars 71. The curvature of the outer side of the arc-shaped strips 73 matches the concave arc-shaped surface 21. The length directions of each crossbar 71 are parallel to each other. The bottom of the brush 3 is connected to the crossbars 71, and adjacent crossbars 71 form a strip-shaped relief groove 72, one end of which forms an opening 74. The oil nozzle 41 and the air nozzle 51 are located inside the relief groove 72.

[0033] When brush 3 needs to be replaced, since brush 3 is fixed on the arc-shaped bracket 7, brush 3 can be replaced by pulling the arc-shaped bracket 7 outward from the concave arc-shaped surface 21. When installing the arc-shaped bracket, during the process of inserting the arc-shaped bracket 7 into the concave arc-shaped surface 21 from one end, the oil outlet 41 and the air outlet 51 slide from the opening 74 into the inner side of the relief groove 72.

[0034] The lower end of the concave arc surface 21 is connected to the feeding plate 6, which is located above the input end of the lower conveyor belt 1. The mooncake 8 first passes through the concave arc surface 21, then slides over the feeding plate 6 and falls onto the lower conveyor belt 1.

[0035] The brush 3 is positioned on the entire outer surface of the concave arc surface 21. This not only cushions the mooncake 8 during flipping, reducing the risk of the mooncake 8's outer skin being crushed, but also allows oil seeping from the oil nozzle 41 to fall onto the brush 3, enabling the mooncake 8 to be oiled as it passes over the brush. The oil nozzle 41 is located on the upper section of the concave arc surface 21 and above the roller 11, facilitating the downward flow of edible oil under its own weight and ensuring contact with all the brushes 3. This not only reduces oil waste but also improves the evenness of oil application.

[0036] When there is a lot of oil on brush 3, the bristles of brush 3 will stick together. In addition, when mooncake 8 passes by, the bristles of brush 3 will deflect towards the lower end of the concave arc surface 21, causing the bristles of brush 3 to fail to return to their original position and face the roller, thus failing to cushion the mooncakes that pass by. To address this, the air outlet 51 is always blowing air, using airflow to allow the bristles of brush 3 to return to their original position as much as possible after brushing oil onto the mooncake 8, ensuring the cushioning effect and extending the service life of the brush.

[0037] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
