Description

Technical Field

[0001] This utility model relates to a dough sheet cutting machine, belonging to the field of food processing machinery technology. Background Technology

[0002] In the pasta processing industry, cutting dough sheets (such as dumpling wrappers and wonton wrappers) is a crucial step. Traditional dough sheet cutting often uses manual or semi-automatic equipment, which suffers from low efficiency, poor cutting accuracy, and limited adaptability. For example, some equipment cannot handle dough sheets of varying thicknesses, the cutter easily damages the conveyor belt, and the dough sheets tend to shift during feeding, affecting cutting quality. Furthermore, the power mechanism is overly complex. Therefore, a highly efficient, precise, and safe dough sheet cutting machine is needed to solve these problems. Utility Model Content

[0003] This invention overcomes the shortcomings of existing technologies and provides a dough cutting machine that optimizes the structure and improves cutting efficiency, precision and safety.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a dough sheet cutting machine, including a frame, a cutter support, a servo motor, and a feeding belt. The feeding belt is horizontally arranged on the frame, and the cutter support is transversely arranged on the frame on both sides of the feeding belt. The servo motor is fixedly arranged on the top of the cutter support, and a reducer is arranged at the output end of the servo motor. The reducer is also fixedly arranged on the top of the cutter support. A crank-connecting rod mechanism is arranged at the power output end of the cutter support. The crank-connecting rod mechanism is connected to a cutter through a guide mechanism fixed to the bottom side of the top of the cutter support. The blade of the cutter faces downward. The cutter can reciprocate and lift under the drive of the servo motor to cut the dough sheet passing through the feeding belt. Two columns are symmetrically and vertically fixed on the frame on the front side of the cutter support. Two guide rollers are arranged at an adjustable height between the columns. A gap is left between the two guide rollers. The cutter can pass through the gap between the guide rollers to cut the material. The guide rollers limit the stroke of the cutter to protect the belt and accommodate dough sheets of different thicknesses.

[0005] Furthermore, a guide wheel assembly is provided on the feeding belt upstream of the cutter. The guide wheel assembly is symmetrically arranged on both sides of the feeding belt to guide the dough past directly below the cutter.

[0006] Furthermore, a sensor assembly is provided on the rotating shaft connecting the reducer and the crank-connecting rod mechanism, and the sensor assembly is used to collect the number of cuts made by the cutter.

[0007] Furthermore, the feed end of the feeding belt is provided with a transition roller assembly, which is used to guide the dough onto the feeding belt. The transition roller assembly is inclined so that the dough can slide onto the feeding belt on its own.

[0008] Furthermore, a material support roller assembly is provided at the intersection of the transition roller assembly and the feeding belt, and the material support roller assembly is used to assist the transition roller assembly in feeding.

[0009] Furthermore, a protective cover is provided on the outside of the cutter holder to cover the cutter and related components, ensuring processing safety.

[0010] Compared with existing technologies, this invention offers the following advantages: It achieves precise reciprocating motion of the cutter through a servo motor and crank-connecting rod mechanism, resulting in fast cutting speed and high efficiency, while simplifying the power structure; the height of the guide roller is adjustable to accommodate different thicknesses of dough sheets and protect the feeding belt; the guide roller assembly ensures stable dough sheet feeding and prevents deviation; the sensor assembly automatically records the number of cuts, facilitating production management; the transition roller assembly and the material support roller assembly simplify the feeding process; and the protective cover enhances operational safety. The overall structure is simple and reliable, suitable for large-scale production. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] like Figure 1 , Figure 2 and Figure 3As shown, this utility model discloses a dough sheet cutting machine, comprising a frame 1, a cutter support 2, a servo motor 3, and a feeding belt 4. The feeding belt 4 is horizontally mounted on the frame 1 and is continuously driven by the motor. The cutter support 2 is fixed across the frame 1 on both sides of the feeding belt 4. The servo motor 3 and a reducer 5 are mounted on top of the cutter support 2. The servo motor 3 outputs power through the reducer 5 to drive the crank-connecting rod mechanism 6. The crank-connecting rod mechanism 6 is connected to a guide mechanism 7, which is a linear guide rail or guide rod structure, ensuring the vertical reciprocating motion of the cutter 8. The cutter 8, with its blade facing downwards, rapidly rises and falls under the drive of the servo motor 3 to cut the dough sheet on the feeding belt 4.

[0018] Two uprights 9 are symmetrically fixed on the frame 1 on the front side of the cutter bracket 2. Two guide rollers 10 are installed on the uprights 9 with adjustable height via threads or slots. The gap between the guide rollers 10 allows the cutter 8 to pass through, and the height of the guide rollers 10 can be adjusted according to the thickness of the dough to prevent the cutter 8 from cutting too deeply and damaging the feed belt 4. The guide rollers 10 also flatten the dough, improving the cutting quality.

[0019] Guide roller assemblies 11 are installed on both sides of the feed belt 4 upstream of the cutter 8. The guide roller assembly 11 consists of multiple rollers and guides the dough sheet to move along the center line, ensuring that the dough sheet passes directly below the cutter 8. A sensor assembly 12, such as a photoelectric encoder or a proximity switch, is installed on the shaft of the reducer 5 to detect the number of times the cutter 8 moves, thereby realizing cut counting.

[0020] A transition roller assembly 13 is installed at the feed end of the feeding belt 4. The transition roller assembly 13 is installed at an angle so that the dough sheet slides down from the previous process onto the feeding belt 4. A material support roller assembly 14 is provided at the intersection of the transition roller assembly 13 and the feeding belt 4. The material support roller assembly 14 is an auxiliary roller that supports the dough sheet for a smooth transition. A protective cover 15 is installed on the outside of the cutter bracket 2 to cover the moving parts such as the cutter 8 and the crank connecting rod mechanism 6, preventing operators from contacting them and ensuring safety.

[0021] During operation, the dough wrappers enter the feeding belt 4 via the transition roller assembly 13 and the support roller assembly 14. The guide roller assembly 11 corrects the position, and the feeding belt 4 transports the dough wrappers to below the cutter 8. A servo motor 3 drives the cutter 8 to reciprocate at high speed. A stop roller 10 limits the cutter's stroke, and a sensor assembly 12 records the number of cuts. A protective cover 15 prevents accidental injury. This invention is suitable for the continuous cutting of dumpling wrappers, wonton wrappers, and other dough wrappers, offering high efficiency and strong adaptability.

[0022] 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.
