Description

Technical Field

[0001] The invention relates to an automatic spring roll production line and belongs to the technical field of spring roll production. Background Art

[0002] In the early days, spring roll production was highly dependent on manual operation, especially in the process of spring roll wrapper forming, filling processing and wrapping, which were inefficient. When making spring roll wrappers manually, there were problems such as slow speed, uneven thickness and low output, which made it difficult to meet the needs of industrial production. Traditional spring roll wrap production relies on manual operation, which requires the batter to be adhered to a preheated pan one by one. This has problems such as high labor intensity, low efficiency, and uneven thickness of the finished product, making it difficult to meet the needs of large-scale production.

[0003] To solve the above problems, some equipment introduces a forming roller structure, and controls the shape of the dough by setting forming holes on the roller. However, this technology still has problems such as slurry stickiness and irregular appearance: When the forming hole and the baking roller roll against each other, the dough is likely to remain in the gap, resulting in rough edges of the spring roll wrapper; the nozzle spraying method has not been fundamentally improved, and there is still a risk of fluctuation in the dough thickness and blockage; some equipment uses electromagnetic heating, which improves energy efficiency but does not solve the problem of uniformity in material collection.

[0004] As the food industry's requirements for automation and standardization increase, the market is in urgent need of a highly efficient, low-consumption, and stable material-removing device that can control the thickness of the slurry. In the existing technology, there is no solution that effectively combines die-removing and precise gap control, which makes it difficult to balance the scale and quality consistency of spring roll wrap production.

[0005] In the automated production process of spring rolls, the rolling and blowing device is a key process link. Traditional spring roll production relies on manual operation, especially in the rolling and wrapping steps, where the fillings need to be manually wrapped in the dough and folded into shape.

[0006] Although early automated equipment (such as the jet unit mentioned in patent CN109548815B) achieves dough positioning or blowing off through jet technology, it still has limitations in the rolling process: 1. Risk of dough damage: Mechanical flipping mechanisms (such as rollers or clamps) may cause dough damage or leakage of fillings due to improper contact force.

[0007] 2. Lack of flexibility: Traditional mechanical rolling devices are difficult to adapt to the production needs of spring rolls of different sizes or recipes.

[0008] 3. Difficulties in cleaning and maintenance: Stuffing or dough debris is easily left on mechanical parts, requiring frequent shutdown for cleaning. Summary of the invention

[0009] The present invention overcomes the shortcomings of the prior art and provides an automatic spring roll production line with an easy-to-control shape and uniform thickness, no nozzle clogging problem, greatly reduced risk of dough damage, easy-to-adjust size, reduced difficulty in cleaning and maintenance, and greatly improved production efficiency.

The heating disk 106 has a built-in electric heating component, and the electric heating component is located on the inner side of the dough forming table 107, and rotates at a constant speed under the drive of the power structure; both ends of the rotating surface of the heating disk 106 are tightly pressed on the transmission roller 1012, and the transmission roller 1012 is connected to the driving motor 1014 through the chain transmission structure 1013.

[0033] The spray box 104 is arranged below the heating plate 106, and the spray box 104 is a hollow triangular structure. A slurry inlet hole 108 is arranged at the front side of the bottom of the spray box 104, and the slurry inlet hole 108 is connected with the discharge port of the slurry suction pipe 103 through a hose.

[0035] In the present invention, the dough is sucked from the dough barrel 101 into the spray box 104 through the suction pump 102. As the heating plate 106 rotates, the connecting rod mechanism 105 drives the spray box 104 to rotate a certain angle under the power of the cylinder 1010, and the slurry in the spray box 104 is blown onto the dough forming table 107 of the heating plate 106 in cooperation with the pressure of the suction pump 102.

The dough blown to the dough forming table 107 is matured under the heating action of the electric heating component, and is flipped to the blanking end and shoveled onto the assembly line for the next step of processing by a scraper.

[0036] The structure of the rolling and blowing device 4 is: including a first flanging mechanism 401, a marking mechanism 402, a second flanging mechanism 403 and a rolling mechanism 404, wherein the first flanging mechanism 401, the marking mechanism 402, the second flanging mechanism 403 and the rolling mechanism 404 are arranged in sequence along the water flow line frame, and the first flanging mechanism 401 is located downstream of the spring roll skin filling.

[0037] The first flanging mechanism 401 and the second flanging mechanism 403 are respectively connected to the high-pressure gas tank 405 through their own blowing pipes, and the air outlet ends of the first flanging mechanism 401 and the second flanging mechanism 403 are provided with flat-mouthed blowing blocks 406, and the blowing ports of the flat-mouthed blowing blocks 406 are vertically upward.

[0038] The marking mechanism 402 is movably arranged on the water flow line frame, and two marking wheels 407 are movably arranged at the end of the marking mechanism 402, and the marking wheels 407 are used to mark the upper side of the dough before the second flanging mechanism 403 flanging the dough; The rolling mechanism 404 includes at least one movable U-shaped metal mesh 408, the lowest end of the metal mesh 408 is in contact with or has a certain gap with the conveyor belt on the upper side of the water flow line frame, and the spring rolls wrapped with fillings after being turned over are passively rolled under the obstruction of the metal mesh 408 when passing between the metal mesh 408 and the conveyor belt to achieve the rolling of the spring rolls.

[0039] An auxiliary flanging mechanism 409 is arranged above the second flanging mechanism 403, and the auxiliary flanging mechanism 409 includes a thin cylinder 4091. Two of the thin cylinders 4091 are fixedly arranged on the water flow line frame, and the thin cylinders 4091 are located directly above the conveyor belt. A horizontal pressure rod 4092 is arranged at the end of the piston rod of the thin cylinder 4091. When the spring roll dough passes below, the pressure rod 4092 is pushed by the thin cylinder 4091 to press the spring roll dough to cooperate with the second flanging mechanism 403 for flanging.

[0040] The pressure rod 4092 and the piston rod end of the thin cylinder 4091 are connected together through an adjustment block 4093, and a long groove 4094 is provided on the adjustment block 4093.

[0041] In the present invention, after the filling is injected, the spring roll dough passes through the first flanging mechanism 401, the marking mechanism 402, the second flanging mechanism 403 and the rolling mechanism 404 in sequence to form a finished spring roll. Specifically, when passing through the first flanging mechanism 401, the upward high-speed airflow will blow the dough in front of the filling upward and fold it backward, and then the marking mechanism 402 will make a mark on the dough on both sides of the filling, and when passing through the second flanging mechanism 403, the upward high-speed airflow will fold the dough on both sides of the filling inward, and when passing through the rolling mechanism 404, the dough with three sides folded is passively rolled under the obstruction of the metal mesh 408 to realize the rolling of the spring roll.
