Description

Technical Field

[0001] This invention relates to the field of food processing machinery technology, specifically to a fully automatic noodle knot machine for producing tofu skin wrapped meat. Background Technology

[0002] Mianjie, also known as tofu skin wrapped meat, is a traditional delicacy in Ningbo and other areas of Jiangsu and Zhejiang provinces. Its production process typically involves several steps, including separating the tofu skin into sheets, placing the meat filling, folding, and rolling it into shape. Currently, the production of mianjie relies primarily on manual labor. This traditional method has several problems: firstly, high labor costs and low production efficiency make it difficult to meet the needs of large-scale production; secondly, due to differences in operator skills, the product shape is difficult to standardize, affecting standardization and aesthetics; and thirdly, hygiene conditions are difficult to maintain consistently and effectively during the manual production process. With the rise of online sales, the market demand for mianjie is increasing daily, and traditional manual production methods can no longer meet the needs of market development in terms of both quantity and quality.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0023] like Figure 1 As shown, a fully automatic dough-making machine includes a frame and a control system (7) mounted on the frame, as well as a wet tofu skin separating machine (1), a tofu skin conveyor belt (6), a filling-pushing machine (2), a lifting-type forward folding device (3), an edge-folding device (4), and a tunnel-type rolling device (5) connected in sequence. All actions are uniformly coordinated and controlled by the control system (7).

[0024] The working process of the wet tofu skin separating machine (1): like Figure 2 As shown, the soaked tofu skin is stacked on the tofu skin lifting device (11) of the tofu skin separating machine (1). The control system (7) controls the lifting device (11) to rise to the height that the gripping device (12) can grab. After the gripping device (12) grabs a tofu skin, the gripping device moving cylinder (13) moves it to the front end of the tofu skin conveyor belt (6). The tofu skin is placed at a 45-degree angle to the conveyor belt, ensuring that its diagonal is aligned with the center line of the conveyor belt. Each time a tofu skin is grabbed, the lifting device (11) rises precisely by the thickness of one tofu skin.

[0025] The working process of the push-type filling machine (2): like Figure 3 As shown, the discharge port of the push-type filling machine (2) is located above the center of the tofu skin conveyor belt (6). The operator puts the meat filling into the hopper (21), and the auger motor drives the auger (22) to press the meat filling downwards into the pushing chamber (23) in a quantitative manner. The control system controls the weight of the meat filling by controlling the working time of the auger motor. When the sensor on the tofu skin conveyor belt (6) detects that the tofu skin has reached the predetermined position, the control system drives the meat filling pushing component (24) at a precise time point to push the meat filling to the discharge port. At the same time, the meat filling pressing component (25) is activated instantly, precisely pressing the long cylindrical meat filling down to the center of the diagonal of the tofu skin. The entire filling process is completed without stopping the conveyor belt.

[0026] The working process of the lever-type forward folding device (3): like Figure 4 As shown, the separating scraper (32) and the lifting rod assembly (31) of the lever-type forward folding device (3) are installed in the gap between the end of the tofu skin conveyor belt (6) and the front end of the folding device (4). The separating scraper (32) separates the wet tofu skin that may adhere to the conveyor belt. When the front end of the tofu skin passes the separating scraper (32) and reaches a certain length above the lifting rod (31), the control system drives the lifting rod (31) to lift it up, folding the front corner of the tofu skin upwards so that it adheres to the meat filling. The lifting point of the lifting rod is slightly lower than the height of the meat filling, using the stickiness of the meat filling to make the front corner of the tofu skin adhere and prevent it from rebounding. After the tail end of the tofu skin passes below the lifting rod, the lifting rod (31) returns to its original position, completing the forward folding action.

[0027] The working process of the folding device (4): like Figure 5 As shown, the folding device (4) consists of a central conveyor belt (41), a left twisting conveyor belt (42), and a right twisting conveyor belt (43), all of which are driven synchronously by the same main drive shaft. After the tofu skin and meat filling enter the folding device, firstly, because the left twisting conveyor belt (42) is shorter, the left side of the tofu skin is gradually folded upwards; then, the right twisting conveyor belt (43) folds the right side of the tofu skin upwards. During the folding process, the pressing strips (44) on both sides of the central conveyor belt (41) press down on the tofu skin to prevent wrinkling. At the same time, the air vents (45) located at an inclination of about 60 degrees on the twisting conveyor belt blow air from the outside to the inside, assisting the tofu skin to gather towards the middle and complete the left and right folding actions.

[0028] The working process of the tunnel winding device (5): like Figure 6 As shown, the semi-finished knot with folded edges enters the tunnel-type rolling device (5). Both the conveyor belt (51) and the upper pressure plate (52) have significant friction, with the upper pressure plate (52) applying pressure to the semi-finished product using its own weight. Under the combined action of the forward conveying force of the conveyor belt (51) and the static pressure of the upper pressure plate (52), the knot is rolled forward and rolled under the guidance of the left and right side plates (53), ultimately forming a complete knot at the tail end of the conveyor belt (51). The spacing between the left and right side plates (53) can be adjusted according to the required knot length.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
