[0002] With societal development, the types and forms of ingredients have become increasingly diverse to meet different needs. For ease of processing and use, many ingredients are diced. For preservation, many ingredients are frozen during storage and transportation, and then diced before use. Since manual dicing is inefficient and difficult, mechanical methods are needed.

[0003] Existing cutting machine types mainly include integrated two-dimensional blade cutting machines, vertical and circular blade combination cutting machines, and three-dimensional centrifugal cutting machines. Among them, integrated two-dimensional blade cutting machines have the following disadvantages: slow cutting speed, poor meat dicing effect, prone to blade brittleness, and once the blades are damaged, they cannot be completely repaired, resulting in high replacement costs. Vertical and circular blade combination cutting machines have the following disadvantages: slow dicing speed and low work efficiency. There is also a three-dimensional centrifugal cutting machine, which has a higher dicing speed, but the cut raw material size is small, generally not exceeding 200mm, the dicing effect is poor, the qualified rate of diced products is low, and the diced size is small, generally not exceeding 20mm.

Detailed Implementation

[0026] The present invention will now be described in detail. Before proceeding with the description, it should be understood that the terminology used in this specification and the appended claims should not be construed as limited to its general or dictionary meaning, but rather should be interpreted according to the meaning and concept corresponding to the technical aspects of the invention, based on the principle that the inventors are allowed to appropriately define the terms for the best interpretation. Therefore, the description presented herein is merely a preferred example for illustrative purposes and is not intended to limit the scope of the invention. It should be understood that other equivalents or modifications can be obtained from it without departing from the spirit and scope of the invention.

[0027] The following embodiments are merely examples illustrating implementations of the present invention and do not constitute any limitation on the present invention. Those skilled in the art will understand that modifications made without departing from the spirit and concept of the present invention fall within the protection scope of the present invention. Unless otherwise specified, the reagents and instruments used in the following embodiments are commercially available products. Example

[0028] A cutting machine, such as Figure 1-3As shown, the system includes a frame 1, on which a feeding system 2, a cutting system 3, and a discharging system 4 are mounted. The cutting system is located at the end of the feeding system, and the discharging system is located below the cutting system. The feeding system is used to feed the food to be processed to the cutting system. The cutting system is used to receive the food fed by the feeding system and cut it. The discharging system is used to receive and output the food cut by the cutting system.

[0029] The feeding system includes a feeding drive device and a feeding conveyor device.

[0030] like Figure 5 As shown, the cutting system includes a longitudinal cutting device, a comb device, and a transverse cutting device. The longitudinal cutting device includes a longitudinal cutting shaft 5 and a grooved roller 6, both of which can rotate around their respective axes of rotation. A longitudinal cutting blade 7 is mounted on the longitudinal cutting shaft. Preferably, the longitudinal cutting blade 7 is a hollow annular shape. The longitudinal cutting shaft 5 passes through the center of the longitudinal cutting blade 7 and fixes it therein. The grooved roller has grooves 8 that are clearance-fitted with the longitudinal cutting blade 7. When the longitudinal cutting shaft 5 and the grooved roller 6 rotate, the longitudinal cutting blade 7 can rotate freely within the grooves 8 on the grooved roller without obstruction. The transverse cutting device includes a transverse cutting shaft 9, which can rotate around its own axis of rotation. A transverse cutting blade 10 is mounted on the transverse cutting shaft. Therefore, as described above, the longitudinal cutting shaft and the transverse cutting shaft each rotate around their respective axes of rotation. The rotational speeds of the longitudinal cutting shaft and the transverse cutting shaft can be independently controlled. They can rotate synchronously at the same speed or rotate relative to each other with a certain speed difference.

[0031] The longitudinal cutting shaft 5 and the transverse cutting shaft 9 are respectively mounted on the longitudinal cutting shaft bearing seat and the transverse cutting shaft bearing seat.

[0032] like Figure 9 , 10 As shown, the comb device includes a comb 11. The fixed end 37 of the comb is connected to the frame 1. The end of the comb opposite to the fixed end is a free end 38. The free end of the comb is located between the longitudinal cutting blade and the transverse cutting blade and extends towards the longitudinal cutting blade. The side of the free end of the comb facing the longitudinal cutting blade is provided with a comb groove 12. The number of comb grooves 12 is the same as the number of longitudinal cutting blades. Each comb groove can accommodate a single longitudinal cutting blade. Each longitudinal cutting blade and the comb groove accommodating it are in clearance fit. The longitudinal cutting blade can rotate freely without obstruction within the comb groove. The end of the free end of the comb is close to the longitudinal cutting axis. The comb groove can peel off the food that has been cut into strips on the longitudinal cutting blade. The longitudinal cutting axis, the comb groove roller, and the transverse cutting axis are arranged parallel to each other. The discharge system includes a discharge drive device and a discharge conveying device.

[0033] With its independently controllable rotation speeds of the longitudinal and transverse cutting axes, the machine can easily cut ingredients into cubes, shreds, and slices of different sizes by simply adjusting their rotation speeds. This allows for diverse functions, and the machine is also simple in structure and highly efficient.

[0034] The free end of the comb has a cross-cutting surface 39 on the side facing the cross-cutting blade. The arc of the cross-cutting surface matches the rotation trajectory generated when the cross-cutting blade 10 rotates, but the two are slightly apart. That is, the arc of the cross-cutting surface is close to the rotation trajectory of the cross-cutting blade 10 but does not hinder the rotation of the cross-cutting blade 10. The bottom of the cross-cutting surface extends towards the free end of the comb to form a cross-cutting edge 13. Therefore, the cross-cutting edge 13 is located at the bottom of the comb. The cross-cutting blade 10 makes a transverse cut at the cross-cutting edge 13 and rotates upward along the cross-cutting surface.

[0035] The feeding system also includes a pressing device, which includes a pressing roller 14 arranged parallel to the longitudinal cutting axis. The pressing roller rotates around its rotation axis and its rotation speed is independently controllable. At the end of the feeding system, a feeding conveying roller 15 is arranged parallel to the pressing roller. The pressing roller is located above the feeding conveying roller. The food ingredients transmitted from the feeding system are transferred to the longitudinal cutting device through the pressing roller and the feeding conveying roller. The pressing roller's height is adjustable. This height adjustment allows products of different thicknesses to pass through smoothly without being crushed.

[0036] The discharge system also includes a baffle plate 36 installed on the box body. The baffle plate is located above the cross-cutting device and is used to block and collect the food that is thrown out by the cross-cutting device.

[0037] A schematic diagram of the cutting linkage mechanism is shown below. Figure 6 As shown, the frame is also equipped with two cutting motors. One cutting motor drives the longitudinal cutting shaft, the groove roller, the feed drive roller, and the discharge drive roller to rotate simultaneously, while the other cutting motor drives the transverse cutting shaft to rotate. Two sets of synchronous pulleys 28 are also provided. The first set has one pulley on each of the longitudinal cutting shaft and the pressure roller shaft, fitted with a synchronous belt 29; the second set has three pulleys on the groove roller shaft, the feed drive roller, and the discharge drive roller, each fitted with a synchronous belt.

[0038] The working principle and process of the cutting machine described in this embodiment are as follows: The feeding system transmits the food to the cutting system. The food passes between the longitudinal cutting shaft 5 and the groove roller 6 and is longitudinally cut into strip-shaped food by the longitudinal cutting blade 7. The longitudinal cutting blade continues to rotate and enters the comb groove 12 of the comb, thereby peeling the strip-shaped food from the longitudinal cutting device. The peeled strip-shaped food is further transversely cut by the transverse cutting blade 10 to obtain the product. The cut product falls into the outer circular groove of the transverse cutting shaft 9 and is taken away. The baffle plate 36 intercepts and collects the food thrown out by the transverse cutting device and then falls onto the discharge system to be output. Example

Multiple transverse cutting blades are arranged parallel to the rotation axis of the transverse cutting axis and are perpendicular to the transverse direction of the longitudinal cutting blades. By adjusting the spacing between adjacent longitudinal cutting blades, the width of the longitudinal cut can be adjusted. Narrowing the spacing results in narrow strips, which, combined with adjusting the transverse cutting speed, yields strips or pieces. Widening the spacing results in wide slices, which, after transverse cutting, yield pieces.

[0042] The comb device also includes a comb holder 19, on which the comb is detachably fixed. The comb holder is fixed to the frame 1. When the spacing of the longitudinal cutting blades is adjusted, the comb groove that matches the longitudinal cutting blade is also replaced accordingly.

[0043] The longitudinal cutting blade has a groove 20 along the circumferential direction. Example
