Description

Technical Field

[0001] This utility model relates to the field of food processing machinery technology, and in particular to an automatic sorting and stacking device for dough blanks. Background Technology

[0002] In the production of pasta, dough is pressed, rolled, or stamped to form a large number of raw dough discs. These discs are usually placed randomly on trays or conveyor belts and need to be manually arranged, spaced out, and stacked in multiple layers for subsequent fermentation, baking, or freezing. Currently, sorting and stacking work mainly relies on manual labor. This method has the following drawbacks: low efficiency: manual operation is slow and difficult to match with high-speed automated production lines, becoming a bottleneck in production. High labor costs: Requires a large investment of manpower, and the work is repetitive and monotonous; Hygiene risks: Human contact with food increases the risk of contamination and does not meet the high hygiene standards of the modern food industry; Poor consistency: The position, spacing, and number of layers of manual stacking may be inconsistent, affecting subsequent processes and product appearance; Therefore, there is an urgent need for equipment that can automatically, efficiently, and hygienically complete the dough preparation, sorting, and stacking processes. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic sorting and stacking device for dough sheet preparation in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes an automatic sorting and stacking equipment for dough blanks, including a frame, a feeding mechanism, a mold positioning mechanism, a pushing mechanism, a control system, and a lifting drive system; the feeding mechanism is located at the center of the frame; the feeding mechanism includes an inclined main conveyor belt, the end of which is inclined downward, for the flat dough blanks to move to the edge and fall vertically by their own weight. The molded positioning mechanism is located below the end of the main conveyor belt. The molded positioning mechanism includes a second conveyor belt that can move intermittently and a vertical baffle. When the vertical baffle is raised, a positioning grid is formed between adjacent baffles to accurately receive a single vertically falling dough piece. The pushing mechanism is located at the end of the molded positioning mechanism, behind the second conveyor belt, and its pushing direction is perpendicular to the direction of movement of the second conveyor belt. It is used to gather a whole row of dough pieces on the second conveyor belt and push them backward. The control system is used to control the various components to work together according to a preset program.

[0005] As a preferred embodiment of this utility model, the baffle lifting drive mechanism is an electric push rod.

[0006] As a preferred embodiment of this utility model, the second conveyor belt has a strip-shaped hole on its surface that allows the vertical baffle to pass through. The bottom of the vertical baffle is fixedly connected to a synchronization plate. The lifting drive system is an electric push rod, whose piston rod is connected to the synchronization plate to drive all the vertical baffles to lift synchronously.

[0007] As a preferred technical solution of this utility model, the cylinder of the electric push rod and the synchronous plate are jointly mounted on the sliding base. A slide rail is provided on the frame, and the slide rail is slidably engaged with the sliding base, so that the entire baffle lifting assembly can reciprocate along the moving direction of the second conveyor belt; the control system controls the assembly to stop accurately at the designated receiving station and pushing station.

It uses a baffle lifting and lowering method instead of flipping or translating to avoid pushing, which has a simple motion path, no risk of interference, and good mechanical stability; 4. It greatly reduces manual labor, lowers the risk of food contamination, and meets the hygiene standards of modern food processing. Attached Figure Description

[0016] As shown in the attached diagram, initially, the vertical baffles on the second conveyor belt are raised under the action of the baffle lifting drive mechanism to form positioning grids, with the first positioning grid located directly below the end of the main conveyor belt. After the dough blanks fall from the main conveyor belt and are accurately guided into the positioning grid, the control system instructs the second conveyor belt to move one grid distance in a step, while simultaneously driving the entire baffle lifting assembly to move synchronously along the guide rail, so that the next empty positioning grid moves to the dropping point to continue receiving material. This process is repeated until all positioning grids are filled, and then the baffles are lowered to the lowered clearance position, and the pushing mechanism then moves to push the entire row of dough blanks to the rear carrying platform to complete one layer of stacking. Finally, all actuators are reset, the carrying platform is lowered by one dough blank height, and the equipment automatically enters the next cycle, realizing the fully automated operation of dough blanks from random incoming material to neat vertical stacking.

[0017] like Figure 1 and Figure 2 As shown, this utility model proposes an automatic sorting and stacking equipment for dough blanks, including a frame, a feeding mechanism, a molded positioning mechanism, a pushing mechanism, a control system, and a lifting drive system; the feeding mechanism is located at the center of the frame; the feeding mechanism includes an inclined main conveyor belt, the end of which is inclined downwards, for the dough blanks to move to the edge and fall vertically by their own weight; The molded positioning mechanism is located below the end of the main conveyor belt. The molded positioning mechanism includes a second conveyor belt that can move intermittently and a vertical baffle. When the vertical baffle is raised, a positioning grid is formed between adjacent baffles to accurately receive a single vertically falling dough piece. The pushing mechanism is located at the end of the molded positioning mechanism, behind the second conveyor belt, and its pushing direction is perpendicular to the direction of movement of the second conveyor belt. It is used to gather a whole row of dough pieces on the second conveyor belt and push them backward. The control system is used to control the various components to work together according to a preset program.

[0018] The baffle lifting drive mechanism is an electric push rod.

[0019] The second conveyor belt has strip-shaped holes on its surface that allow the vertical baffles to pass through. The bottom of the vertical baffles is fixedly connected to a synchronization plate. The lifting drive system is an electric push rod, whose piston rod is connected to the synchronization plate to drive all the vertical baffles to lift and lower synchronously.

[0020] The second conveyor belt has strip-shaped holes on its surface that allow the vertical baffles to pass through. The bottom of the vertical baffles is fixedly connected to a synchronization plate, which is an electric push rod whose piston rod is connected to the synchronization plate to drive all positioning baffles to rise and fall synchronously.

[0021] The cylinder of the electric push rod and the synchronous plate are mounted together on the sliding base. A slide rail is provided on the frame, and the slide rail is slidably engaged with the sliding base, so that the entire baffle lifting assembly can reciprocate along the moving direction of the second conveyor belt. The control system controls the assembly to stop accurately at the designated receiving station and pushing station.

[0022] The push mechanism is equipped with a liftable support platform at its rear.

[0023] The control logic of the control system is as follows: control the positioning baffle to be in the raised working position, and control the second conveyor belt to move step by step, so that each positioning grid moves to the receiving station in sequence to receive the material. Once all the positioning grids have received one piece of cake, the lifting and lowering drive mechanism of the positioning baffle is activated, causing all the positioning baffles to descend to the lowered clearance position to make way for an unobstructed path for pushing. Then, the pushing mechanism is controlled to push the entire row of dough pieces away from the second conveyor belt; then, each mechanism is controlled to reset and the next cycle begins.

[0024] The second conveyor belt has flexible sealing elements installed at the strip-shaped holes or series of holes on its surface to prevent material debris from falling below the conveyor belt.

[0025] The top edge of the positioning baffle is arc-shaped or has a guide slope.

[0026] Working principle: After the equipment starts, the lifting positioning baffles on the second conveyor belt first rise to form positioning grids, and then move the first positioning grid step by step to directly below the end of the inclined main conveyor belt. After the dough blanks fall from the main conveyor belt, they are accurately guided into the positioning grids. Then the second conveyor belt indexes the next empty space to continue receiving material until all positioning grids are filled. At this time, all positioning baffles are lowered below the surface of the conveyor belt to make way. The pushing mechanism then acts to smoothly push the row of dough blanks that are standing upright on the conveyor belt to the lifting and lowering support platform behind to complete one layer of stacking. Finally, all actuators reset, the support platform lowers by one dough blank height, and the equipment automatically repeats the above process to achieve continuous automated multi-layer stacking.
