Description

Technical Field

[0001] This utility model relates to a batter feeding device for automatic spring roll production, belonging to the field of spring roll production technology. Background Technology

[0002] Traditional spring roll wrapper making relies on manual labor, requiring each wrapper to be individually adhered to a preheated pan. This method is labor-intensive, inefficient, and produces unevenly thick wrappers, making it unsuitable for large-scale production. While early mechanized equipment automated the process by spraying batter onto baking rollers, it still suffers from the following drawbacks:

[0003] 1. Poor thickness control: The uneven distribution of the paste due to fluctuations in the viscosity of the paste when spraying with nozzles affects the taste and appearance of the spring roll wrappers;

[0004] 2. Significant waste of slurry: After continuous spraying to form long strips of skin, cutting is required, resulting in a large amount of scrap (about 30% of the cutting waste), and the waste cannot be recycled due to curing.

[0005] 3. Frequent equipment maintenance: Nozzles are prone to clogging, requiring machine shutdown for cleaning, which reduces production efficiency.

[0006] To address these issues, some equipment incorporates a forming roller structure, using forming holes on the roller to control the shape of the slurry. However, this technology still suffers from problems such as slurry viscosity and irregular appearance.

[0007] When the forming hole and the baking roller roll against each other, the batter is easy to remain in the gap, resulting in rough edges on the spring roll wrappers; the nozzle spraying method has not been fundamentally improved, and there is still a risk of batter thickness fluctuation and clogging; some equipment uses electromagnetic heating, which improves energy efficiency, but does not solve the problem of uniform material feeding.

[0008] With the increasing demands for automation and standardization in the food industry, the market urgently needs a material handling device that is efficient, low-consumption, and can stably control the thickness of the slurry. Currently, there is no effective solution that combines mold-based material handling with precise gap control, making it difficult to balance large-scale production with consistent quality in spring roll wrapper production. Utility Model Content

[0009] This invention overcomes the shortcomings of existing technologies and provides a batter feeding device for automatic spring roll production. The device has an easily controllable shape, uniform thickness, and does not cause nozzle clogging, thus greatly improving production efficiency.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a batter feeding device for automatic spring roll production, including a batter tank, a batter pump, a batter suction pipe, a batter spraying box, a linkage mechanism and a heating plate;

[0011] The inlet of the suction pipe extends into the slurry tank, and the outlet of the suction pipe is connected to the spray box. A slurry pump is installed on the suction pipe to suck the slurry from the slurry tank into the spray box.

[0012] The cylindrical heating plate has a horizontally arranged rotating shaft. Multiple raised dough forming platforms are evenly distributed on the rotating surface of the heating plate. The heating plate has an internal electric heating component located inside the dough forming platform and rotates at a uniform speed under the drive of the power structure.

[0013] The spray box is located below the heating plate. The spray box has a hollow triangular structure. A slurry inlet is provided at the bottom front side of the spray box. The slurry inlet is connected to the outlet of the slurry suction pipe through a flexible hose. A flat slurry outlet is provided on the top side of the spray box. The upper back of the spray box is movably connected by a linkage mechanism. Under the power of the cylinder, the linkage mechanism can drive the spray box to rotate at a certain angle, blowing the slurry in the spray box onto the slurry forming table of the heating plate.

[0014] Furthermore, the two ends of the shotcrete box are hinged to the frame, and the shotcrete box is provided with a limiting rod to restrict its rotation angle.

[0015] Furthermore, the two ends of the rotating surface of the heating plate are pressed tightly against the transmission roller, and the transmission roller is poweredly connected to the drive motor through a chain transmission structure.

[0016] Furthermore, a return funnel is provided below the spray box, and the bottom of the return funnel is connected to the paste bucket through a return pipe. The return funnel is used to collect the paste that falls from the spray box or heating plate.

[0017] Furthermore, a return filter cover is provided on the dough slurry bucket, and the return end of the return pipe extends into the return filter cover.

[0018] Compared with the prior art, the advantages of this utility model are: This utility model uses the raised slurry forming platform to control the shape of the dough, and uses the pressure of the pump body and the rotational inertia of the spray box to blow out the slurry onto the slurry forming platform to form a uniform thickness, without the problem of nozzle clogging, which greatly improves production efficiency.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] like Figure 1 , Figure 2 As shown, this utility model discloses a batter feeding device for automatic spring roll production, which includes a batter tank 1, a batter pump 2, a batter suction pipe 3, a batter spraying box 4, a linkage mechanism 5, and a heating plate 6.

[0025] The inlet of the suction pipe 3 extends into the slurry tank 1, and the outlet of the suction pipe 3 is connected to the spray box 4. The suction pipe 3 is equipped with a slurry pump 2, which sucks the slurry from the slurry tank 1 into the spray box 4.

[0026] The cylindrical heating plate 6 has a horizontally arranged rotating shaft. Multiple raised dough forming platforms 7 are evenly distributed on the rotating surface of the heating plate 6. The heating plate 6 has an internal electric heating component, which is located inside the dough forming platform 7 and rotates at a uniform speed under the drive of the power structure. The two ends of the rotating surface of the heating plate 6 are pressed tightly against the transmission roller 12. The transmission roller 12 is poweredly connected to the drive motor 14 through the chain transmission structure 13.

[0027] The spray box 4 is located below the heating plate 6. The spray box 4 has a hollow triangular structure. A slurry inlet 8 is provided at the bottom front side of the spray box 4. The slurry inlet 8 is connected to the outlet of the suction pipe 3 through a flexible hose. A flat slurry outlet 9 is provided on the top side of the spray box 4. The upper back of the spray box 4 is movably connected by a linkage mechanism 5. Under the power of the cylinder 10, the linkage mechanism 5 drives the spray box 4 to rotate at a certain angle, blowing the slurry in the spray box 4 onto the surface slurry forming table 7 of the heating plate 6. The two ends of the spray box 4 are hinged to the frame, and a limiting rod 11 is provided on the spray box 4 to limit its rotation angle.

[0028] A return funnel 15 is provided below the spray box 4. The bottom of the return funnel 15 is connected to the slurry tank 1 through a return pipe 16. The return funnel 15 is used to collect the slurry that falls from the spray box 4 or the heating plate 6. A return filter cover 17 is provided on the slurry tank 1. The return end of the return pipe 16 extends into the return filter cover 17.

[0029] In this invention, the slurry is drawn from the slurry tank 1 into the spray box 4 by the slurry pump 2. As the heating plate 6 rotates, the linkage mechanism 5, under the power of the cylinder 10, drives the spray box 4 to rotate at a certain angle. The pressure of the slurry pump 2 blows the slurry in the spray box 4 onto the slurry forming platform 7 of the heating plate 6. The residual or fallen slurry falls into the return funnel 15, passes through the return pipe 16 and the return filter cover 17, and enters the slurry tank 1. The slurry blown onto the slurry forming platform 7 is heated and matured by the electric heating component. When it is flipped to the discharge end, it is scraped off by the scraper and placed onto the production line for the next processing step.

[0030] This invention utilizes the raised dough forming platform 7 to control the shape of the dough. The dough blown out by the pressure of the pump body and the rotational inertia of the spray box 4 falls onto the dough forming platform 7 to form a uniform thickness. This avoids the problem of nozzle clogging and greatly improves production efficiency.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
