Description

Technical Field

[0001] This application relates to the field of machinery and equipment for processing soybean products, and in particular to a novel soybean skin cutting device. Background Technology

[0002] Bean curd sheets are a popular bean product. During production, large sheets are typically cut into smaller pieces of a specified size for packaging, transportation, and sales. Currently, many small and medium-sized bean product processing enterprises still rely primarily on manual cutting, with operators using knives to slice the bean curd sheets horizontally and vertically along a ruler. This manual cutting method has several drawbacks: First, it is inefficient and labor-intensive, failing to meet the demands of large-scale production; second, manual cutting results in inconsistent dimensions and varying product quality, affecting appearance; third, operators directly handle sharp knives, posing significant safety hazards; and finally, the cutting process easily contaminates the bean curd sheets, compromising food hygiene and safety.

[0003] Although some companies have attempted to use automated equipment, existing equipment is often complex in structure, expensive, or prone to reduced cutting accuracy due to bean skin displacement and wrinkling during the cutting process, failing to adequately meet actual production needs. Therefore, a novel bean skin cutting device is provided to address these issues. Utility Model Content

[0004] This application provides a novel bean curd skin cutting device that solves the problems mentioned in the background art.

[0005] This application provides a novel bean curd skin cutting device, including a frame and a feeding section, a photoelectric sensor meter, a cross-cutting section, a longitudinal cutting section, and a controller arranged sequentially from front to back on the frame.

[0006] The conveying section includes two rollers horizontally mounted on the frame, a conveyor belt sleeved on the two rollers, and a motor connected to one end of one of the rollers.

[0007] The photoelectric sensor meter is located on the lower top surface of the frame and between the conveying section and the cross-cutting section;

[0008] The transverse section includes two rollers horizontally mounted on the frame, a conveyor belt mounted on the two rollers, a motor connected to one of the rollers, a transverse cutting mechanism located at the top of the frame, and two pressure foot mechanisms located on both sides of the transverse cutting mechanism.

[0009] The longitudinal section includes two rollers horizontally mounted on the frame, three conveyor belts equidistantly mounted on the two rollers, a motor connected to one end of one of the rollers, and a longitudinal cutting mechanism mounted on the frame.

[0010] The controller is located on the outer wall of the frame and is electrically connected to the photoelectric sensor, motor one, motor two, motor three, cross-cutting mechanism, presser foot mechanism and longitudinal cutting mechanism.

[0011] Furthermore, the cross-cutting mechanism includes a cross-cutting cylinder, a cutter holder located at the output end of the cross-cutting cylinder, and a replaceable cutter located on the cutter holder; the presser foot mechanism includes a presser foot cylinder and a presser foot located at the output end of the presser foot cylinder.

[0012] Furthermore, the two ends of the cutter are movably positioned within two cutter movement tracks located on the inner walls of the frame on both sides.

[0013] Furthermore, the longitudinal cutting mechanism includes a cutting shaft, a motor located at one end of the cutting shaft, and two disc cutting blades equidistantly positioned on the cutting shaft.

[0014] Furthermore, the two disc cutters are located in the gaps between the three adjacent conveyor belts.

[0015] Furthermore, the surfaces of conveyor belt one, conveyor belt two, and conveyor belt three are all provided with anti-slip textures.

[0016] Furthermore, a leg is provided at each of the four corners of the bottom of the frame.

[0017] As can be seen from the above technical solution, this application provides a novel bean curd skin cutting device, including a frame and a feeding section, a photoelectric sensor, a transverse cutting section, a longitudinal cutting section, and a controller arranged sequentially from front to back on the frame. The feeding section is used to smoothly feed large sheets of bean curd skin from the previous process into the device. The photoelectric sensor is used to detect the length of the bean curd skin that passes through. The transverse cutting section is used to cut the bean curd skin transversely at a set length. The longitudinal cutting section is used to longitudinally cut the transversely cut strips of bean curd skin. The controller is used to coordinate and control the orderly operation of each component.

[0018] The cross-cutting section includes a cross-cutting mechanism and a presser foot mechanism. When cross-cutting the bean curd skin, the presser foot mechanism first presses the skin down, and then the cross-cutting mechanism cuts it, effectively preventing the skin from shifting or wrinkling during cutting, thus ensuring a straight cut edge. The longitudinal cutting section uses multiple parallel conveyor belts in conjunction with disc cutters positioned between the conveyor belts, achieving simultaneous longitudinal cutting during transport, resulting in a smooth and efficient process. Furthermore, each conveyor belt surface is textured with anti-slip material to increase friction and prevent the bean curd skin from slipping during transport.

[0019] In summary, the beneficial effects of this application are as follows:

[0020] 1. This device, through the cooperation of a photoelectric sensor and a PLC controller, achieves accurate measurement and automatic cutting of bean curd skin length, ensuring product size consistency and significantly improving product quality.

[0021] 2. A presser foot mechanism is set in the cross-cutting section, which can effectively press the bean skin before cutting, avoiding the size error and uneven cutting edge problems caused by material movement in traditional cutting.

[0022] 3. The material conveying, cross-cutting and longitudinal cutting processes of this device are seamlessly connected, realizing continuous operation, greatly improving production efficiency, and reducing labor costs and labor intensity.

[0023] 4. The entire cutting process is completed automatically inside the equipment, and the operator does not need to directly contact the cutting parts, which fundamentally eliminates the safety hazards of hand-held cutting. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0032] From the above technical solutions, it can be seen that:

[0033] Example 1:

[0034] See Figures 1-4 .

[0035] A novel bean curd skin cutting device uses a rigid frame 1 as the main body. During operation, large sheets of bean curd skin are directly conveyed from the previous process to the conveying section. The conveying section is driven by motor 4 to rotate roller 2, and the cross-cutting section is driven by motor 7 to rotate roller 5. These motors drive the conveyor belts 3 and 6, which have anti-slip textures on their surfaces, to move and convey the large sheets of bean curd skin backward.

[0036] Large sheets of bean curd skin pass under the photoelectric sensor 14, which measures the length of the bean curd skin. When the measured length reaches the preset cross-cutting length value in the controller 21, the photoelectric sensor 14 sends a signal to the controller 21. The controller 21 (usually a PLC) then controls motor 4 and motor 7 to stop. Immediately afterwards, the controller 21 controls the two presser foot cylinders 15 to move, driving the presser foot 16 downward to firmly press the large sheets of bean curd skin onto the conveyor belt 6. Subsequently, the cross-cutting cylinder 17 moves, pushing the cutter frame 18 downward along the cutter movement track 22 on both sides of the frame 1. The replaceable cutter 19 installed on the cutter frame 18 completes the cross-cutting of the bean curd skin. After the cross-cutting is completed, the presser foot 16 and the cutter 19 reset, and the conveying section and the cross-cutting section resume operation, sending the cut bean curd skin strips backward into the longitudinal cutting section.

[0037] The longitudinal cutting section consists of three equally spaced conveyor belts 9 with anti-slip textures on their surfaces, driven by a motor 10. Simultaneously, the motor 11 of the longitudinal cutting mechanism drives the cutting shaft 12 to rotate at high speed. Two disc cutting blades 13 mounted on the shaft are positioned precisely in the two gaps between the three conveyor belts 9. When the bean curd strip enters the longitudinal cutting section, its left and right sides are carried and transported by the two conveyor belts 9, while the middle part is suspended in the gap. The high-speed rotating disc cutting blades 13 longitudinally cut the suspended bean curd strip from below, thereby evenly dividing a bean curd strip into three bean curd pieces of the same size, which are finally output from the end of the device, completing the entire cutting process.

[0038] As a preferred embodiment, a leg is provided at each of the four corners of the bottom of the frame.

[0039] Working principle:

[0040] Feeding and conveying: The large sheets of bean curd sheets output from the previous process are directly conveyed to the first conveyor belt 3, which is in operation. Driven by the first motor 4, the large sheets of bean curd sheets are smoothly conveyed backward.

[0041] Photoelectric metering and triggering: When the front end of the large bean curd sheet passes under the photoelectric sensor 14, it is detected by the sensor. The controller 21 starts to count the running distance (or time) of the second conveyor belt 6. When the preset cutting length is reached, the controller 21 issues a command.

[0042] Cross-cutting action: Under the control of controller 21, motor 4 and motor 7 are stopped, so that the bean curd sheets on the second conveyor belt 6 stop at the predetermined position. Then, the two presser foot cylinders 15 are controlled to act simultaneously, driving the presser foot 16 downward to firmly press the part of the large bean curd sheet to be cut onto the second conveyor belt 6. Immediately afterwards, the cross-cutting cylinder 17 is activated, pushing the cutter holder 18 and the cutter 19 downward along the track 22 to complete the cross-cutting. After the cutting is completed, the cross-cutting cylinder 17 and the presser foot cylinder 15 are reset in sequence, and controller 21 continues to count the running distance (or time) of the second conveyor belt 6.

[0043] Longitudinal cutting action: Under the control of controller 21, motor 4 and motor 7 resume operation, driving the transversely cut bean curd strips to continue forward. After entering the longitudinal cutting section, the bean curd strips fall onto the three parallel third conveyor belts 9 and are conveyed forward. When passing the high-speed rotating disc cutter 13, the bean curd part located in the gap between the two third conveyor belts 9 is longitudinally cut, thereby dividing a wide bean curd strip into three bean curd blocks of equal width.

[0044] Discharge: The longitudinally cut bean curd sheets continue to move forward with the third conveyor belt 9, and are eventually collected or sent to the next process. The entire process is repeated, realizing continuous, automatic, and precise cutting of bean curd sheets.
