Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a cutting machine. Background Art

[0002] With the acceleration of industrialization, the food processing industry has increasingly higher requirements for work efficiency and product quality. Food materials with high density and hard texture, such as carrots, potatoes, pumpkins, and betel taro, usually need to be cut into small food segments of appropriate length and width before further processing. The existing cutting method usually requires manual cutting and segmenting with a kitchen knife. This method has high labor intensity, low work efficiency, and the cut food segments are inconsistent in shape and size, which cannot meet the quality standards. If the existing continuous cutting machine is used, there are also problems such as fast cutting speed, fast blade wear caused by continuous cutting, high maintenance cost, poor cutting accuracy, and uneven cutting.

[0017] The beneficial effect is that the present application connects the transmission mechanism to the cutting mechanism and the feed conveyor belt respectively, and controls the intermittent movement of the transmission mechanism to control the feed conveyor belt to intermittently convey the food forward, and at the same time drives the cutting mechanism to move up and down to intermittently cut and cut the food into strips; more specifically, when the food is put on the feed conveyor belt, the first drive device drives the transmission disk to rotate and simultaneously drives the indexing disk to rotate, the indexing disk rotates with the transmission shaft, the transmission shaft drives the feed conveyor belt to intermittently convey the food forward, and at the same time, as the indexing disk rotates, it can also drive the connecting plate to slide up and down on the inner wall of the shell along the sliding assembly, and because the connecting plate is fixed to one side of the cutting mechanism The cutting mechanism is connected, so the cutting mechanism will move up and down with the rotation of the indexing plate to cut and cut the food into strips. In short, by controlling the rotation of the transmission mechanism, when the cutting mechanism is lifted, the food is fed forward with the intermittent transmission mechanism, and when the cutting mechanism falls, the food stops feeding. In this way, driven by the transmission mechanism, the up and down cutting speed of the cutting mechanism can be kept consistent with the speed at which the feeding conveyor belt feeds the food forward, so as to ensure the cutting quality of the food and make the cut food segments consistent in shape and size. Through this intermittent cutting method, the cutting process can be finely controlled to ensure that the quality standards of industrial batch cutting are met, reduce blade wear, reduce maintenance costs, and improve work efficiency.

[0050] See also Figure 6 , Figure 6 The first cutting assembly 32 includes a cutting blade 321 and a pre-tensioning component 322 , wherein one end of the cutting blade 321 is fixedly connected to the first column 311 through a fixing member, and the other end of the cutting blade 321 is fixedly connected to the second column 312 through the pre-tensioning component 322 .

The slitting blades 331 can be configured in the shape of a rectangle, a triangle, a circle, or a trapezoid. The preferred trapezoidal structure is beneficial for maintaining blade stability and reducing vibration when cutting hard food. The plurality of slitting blades 331 are sleeved on the core shaft 333. Each two slitting blades 331 are separated by an isolation positioning block 332. The spacing between each two slitting blades 331 is 2 to 5 mm.

Specifically, the convex fixing piece 3332 is provided with a long axis hole that matches the specifications of the core shaft 333. The core shaft 333 passes through the long axis hole.

[0052] By adding a pre-tensioning component 322 to the first cutting component 32 and a pre-tensioning nut 3333 to the second cutting component 33, the tension of the blade is enhanced, thereby improving the cutting force of the first cutting component 32 and the second cutting component 33. During specific operation, the bolt 3223 can be rotated to make the dovetail pre-tensioning slider 3221 move in the mounting groove 3121 to increase the tension of the cutting blade 321. Similarly, the tension of the slitting blade 331 can be changed by tightening or loosening the pre-tensioning nut 3333.

[0053] In order to further improve the cutting force of the blade, the cutting blade 321 and the slitting blade 331 can be improved, and a nano-TiBCrC coating is coated on the substrate surface of the cutting blade 321 and the slitting blade 331, wherein the substrate material is selected from high-speed steel, cemented carbide or ceramic, and the thickness of the nano-TiBCrC coating is 30 to 50 nm. This nano-TiBCrC coating has high hardness, good physical and mechanical properties, thermal stability, oxidation resistance and wear resistance, and has a high bonding strength with the substrate.

[0054] See also Figure 5 The pressure block assembly 34 includes a compression spring rod 341 and a pressure block 342. The top of the compression spring rod 341 is fixedly connected to the top plate 313 along the Z-axis direction. Specifically, a second threaded structure is provided on the top of the compression spring rod 341, and a fixing nut 343 is sleeved on the second threaded structure. The top of the compression spring rod 341 passes through the top plate 313 and is locked and fixed by the fixing nut 343, and the bottom of the compression spring rod 341 is fixedly connected to the pressure block 342.

[0055] When in use, driven by the transmission mechanism 2, as the sliding assembly moves up and down on the inner wall of the housing 1, when the cutting mechanism 3 moves up, the food comes to the bottom of the cutting mechanism 3 along the feeding conveyor belt 41, and as the cutting mechanism 3 moves down, the food is pressed by the block pressing assembly 34, and at the same time, the food is cut and cut into strips by the cooperation of the first cutting assembly 32 and the second cutting assembly 33, so as to obtain small food segments of predetermined length and width. The cutting mechanism 3 has a strong cutting force and clean cutting, and is particularly suitable for food with high density and hard texture. The cut food segments are uniform in size, and the blade does not need to be replaced frequently, and the food is durable and wear-resistant.

[0056] In summary, when the cutting machine is in use, the food to be cut is first stored in the feed bin 6, and then the robot pushes the food into the food conveying channel on the feed conveyor belt 41, and then the first driving device 21 drives the transmission disk 221 to rotate and synchronously drives the dividing disk 224 to rotate, and the dividing disk 224 rotates together with the transmission shaft 225, and the transmission shaft 225 drives the feed conveyor belt 41 to intermittently convey the food forward, and at the same time, as the dividing disk 224 rotates, it can also drive the connecting plate 223 to slide up and down along the sliding assembly on the inner wall of the shell 1, and the connecting plate 223 is fixedly connected to one side of the cutting mechanism 3, so the cutting mechanism 3 will rotate with the dividing disk 22 4 rotates up and down to cut and cut the food. In short, by controlling the rotation of the transmission mechanism 2, when the cutting mechanism 3 is lifted, the food is intermittently fed forward along with the transmission mechanism 2, and when the cutting mechanism 3 falls, the food stops feeding. In this way, driven by the transmission mechanism 2, the up and down cutting speed of the cutting mechanism 3 and the speed of the feeding conveyor belt 41 feeding the food forward can be kept consistent, so as to ensure the cutting quality of the food and make the cut food segments consistent in shape and size. Through this intermittent cutting method, the cutting process can be finely controlled to ensure that the quality standards of industrial batch cutting are met, reduce blade wear, reduce maintenance costs, and improve work efficiency.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
