Description

Technical Field

[0001] The utility model relates to food processing equipment, in particular to a meat roll forming and cutting machine. Background Art

[0002] Meat roll is a strip-shaped food formed by wrapping the filling (mainly pork or other meat) with skin (such as tofu skin).

[0003] When making meat rolls by traditional methods, after the fillings and skins are prepared (the skins are pre-cut single sheets of a certain size), the fillings are manually wrapped with skins to complete the forming process. This production method has a low degree of automation, low production efficiency, high labor costs, and the shape of the meat rolls is not beautiful enough.

[0004] The Chinese utility model patent with publication number CN104432257A discloses a shrimp roll production device, including a conveyor belt, a feeding device, a winding device and a cutting device; the feeding device includes a spray nozzle and a cross bar for fixing the spray nozzle, the cross bar is arranged directly above the conveyor belt, the winding device includes a conical reel and a driving device, and a water spray pipe is arranged above the conical reel; the conveyor belt is used to transport the bean curd skin to the bottom of the spray nozzle, the bottom of the conical reel and the bottom of the cutter in sequence; the feeding device applies the shrimp roll slurry on the bean curd skin through the spray nozzle; the conical reel of the winding device rotates under the drive of the driving device, and the bean curd skin coated with the shrimp roll slurry is rolled up to form a long shrimp roll, and the cutting device is used to divide the long shrimp roll into equal length segments. The cutting device includes a power device and a cutter, and the cutter reciprocates up and down under the drive of the power device to cut the long shrimp roll. The various mechanisms of the shrimp roll making equipment cooperate with each other, and utilize the adhesion between the reel and the shrimp roll slurry and the transmission cooperation of the conveyor belt to roll the tofu skin coated with the filling into a long strip wrapped with the filling, and then automatically complete the entire shrimp roll making process.

[0005] However, since tofu skin and other skin materials are relatively flexible and the fillings are relatively soft, when the cutting knife is cut by reciprocating up and down motion, the long strips of meat rolls are subjected to cutting force from above, so the cuts of the long strips of meat rolls are prone to deformation, and sometimes the tofu skin on the lower side cannot be completely cut off, affecting the appearance and quality of the final product. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide a meat roll forming and slitting machine, which can realize the winding and forming of meat rolls and smoothly cut them into sections, making the products more beautiful. The technical solutions adopted are as follows:

[0007] A meat roll forming and slitting machine comprises a frame, a leather material supply mechanism, a filling material supply mechanism, a conveyor belt, a cross-cutting mechanism, a winding forming cylinder and a winding forming cylinder driving device capable of driving the winding forming cylinder to rotate, wherein the filling material supply mechanism, the conveyor belt, the winding forming cylinder driving device and the cross-cutting mechanism are all installed on the frame, the leather material supply mechanism is arranged in front of the conveyor belt, the winding forming cylinder is located above the conveyor belt, the discharge port of the filling material supply mechanism is located above the conveyor belt and in front of the winding forming cylinder, and the cross-cutting mechanism is arranged behind the conveyor belt, and is characterized in that: the cross-cutting mechanism comprises A knife seat, a left cutter and a right cutter, the knife seat is provided with a cutter guide groove running left and right, the left cutter and the right cutter are both in the cutter guide groove, the left cutter and the right cutter are stacked front to back, and the cross-cutting mechanism also includes a cutter position switching mechanism that can drive the left cutter and the right cutter to move relative to each other; the left cutter is provided with a first material strip through hole, and a left blade is provided on the left inner edge of the first material strip through hole; the right cutter is provided with a second material strip through hole, and a right blade is provided on the right inner edge of the second material strip through hole, the second material strip through hole corresponds to the position of the first material strip through hole, and the right blade corresponds to the position of the left blade.

[0008] The above-mentioned skin material supply mechanism transfers the skin material (such as bean curd skin) to the conveyor belt, and then the conveyor belt conveys the skin material from front to back. When the skin material reaches the position of the discharge port of the filling material supply mechanism, the filling material (the main component of the filling material is pork or other meat) extruded from the discharge port of the filling material supply mechanism is stacked on the skin material; then, when the skin material stacked with the filling material reaches the position of the winding forming cylinder, one side of the skin material is lifted up by the winding forming cylinder, and in the process of moving from front to back with the conveyor belt, it is continuously wound by the winding forming cylinder; when a certain section of the skin material passes over the winding forming cylinder, the section of the skin material completely wraps the filling material, completing the winding and wrapping process, and obtaining a long strip of meat roll; the long strip of meat roll is then sent to the cross-cutting mechanism, and the cross-cutting mechanism cross-cuts the long strip of meat roll to obtain a meat roll of a certain length.

[0045] refer to Figure 6 In the cross-cutting mechanism 5, it is necessary to align the second material strip through hole 57 with the first material strip through hole 55 when the meat roll strip 9 passes through. After the front end of the meat roll strip 9 passes through the first material strip through hole 55 and the second material strip through hole 57 for a certain length, the left cutter 52 and the right cutter 53 move relative to each other under the drive of the cutter position switching mechanism. At this time, the left blade 56 and the right blade 58 move toward each other (that is, the left blade 56 moves to the right, and the right blade 58 moves to the left at the same time; refer to Figure 7When shearing, the left blade 56 moves to the right and the right blade 58 moves to the left, the upper end of the left blade 56 intersects with the upper end of the right blade 58, and the lower end of the left blade 56 intersects with the lower end of the right blade 58, and shearing force is generated on the upper and lower sides of the meat roll strip 9 at the same time). The left blade 56 and the right blade 58 cooperate with each other to shear the meat roll strip 9 (at this time, the second material strip through hole 57 and the first material strip through hole 55 are staggered in the horizontal direction); after the shearing is completed, the cutter position switching mechanism drives the left cutter 52 and the right cutter 53 to move in the opposite direction and reset, at this time, the second material strip through hole 57 and the first material strip through hole 55 are realigned with each other; this cycle is repeated to cross-cut the meat roll strip 9 section by section.

[0046] The length of the meat roll can be adjusted by adjusting the action frequency of the cutter position switching mechanism and the conveying speed of the conveyor belt.
