[0002] In the tea cake market, you can often see cake-shaped tea cakes, which are specially made to make it easy for customers to carry and store after purchase. However, after customers buy cake-shaped tea cakes and take them home, they need to cut them into small pieces before using them. Not only do customers find the operation cumbersome, but it also causes the tea cake residue to fall off after separation, which is a wasteful behavior.

[0057] The target object cutting device described in any one of the above is applied in the processing industry to cut tea cakes.

[0058] Place the target object on the manual rotating positioning table assembly 9, and the tool holder assembly 5 and the supporting sheet metal assembly 6 press and cut the target object downward along the direction of the longitudinal optical axis sliding guide assembly 8 under the drive of the longitudinal screw sliding assembly 7. After the tool holder assembly 5 presses and cuts the target object downward, the tool holder assembly 5 and the supporting sheet metal assembly 6 move upward along the direction of the longitudinal optical axis sliding guide assembly 8 under the drive of the longitudinal screw sliding assembly 7, leaving the pressing and cutting position. The rotating table 9-2 is at the current position, and the rotating table 9-2 is rotated by the rotating handle 9-1 of the manual rotating positioning table assembly 9. After rotating 90° to the left, the rotating positioning table assembly 9 will be stuck by the spring positioning bead 9-5. At this time, the frame assembly 5 and the supporting sheet metal assembly 6 press and cut the target object again downward along the direction of the longitudinal optical axis sliding guide assembly 8 under the drive of the longitudinal screw sliding assembly 7, and the target object can be pre-separated by the device.

[0059] Take tea cake as an example:

[0060] Initially, the tea cake is placed on the manual rotating positioning table assembly 9. The tea cake does not move in the limited position under the action of the target object centering block 9-6. The tool holder assembly 5 and the supporting sheet metal assembly 6 are driven by the longitudinal screw sliding assembly 7 and press and cut the tea cake downward along the direction of the longitudinal optical axis sliding guide assembly 8. After the tool holder assembly 5 presses and cuts the tea cake downward, the tool holder assembly 5 and the supporting sheet metal assembly 6 are driven by the longitudinal screw sliding assembly 7 and move upward along the direction of the longitudinal optical axis sliding guide assembly 8, leaving the pressing and cutting position. The rotating table 9-2 is in the current position, and the rotating table 9-2 is rotated by manually rotating the rotating handle 9-1 of the positioning table assembly 9. After rotating 90° to the left, the rotating positioning table assembly 9 will be stuck by the spring positioning bead 9-5. At this time, the frame assembly 5 and the supporting sheet metal assembly 6 are driven by the longitudinal screw sliding assembly 7 and slide along the direction of the longitudinal optical axis sliding guide assembly 8 to press and cut the tea cake again. The target object can be pre-separated by the device. At this time, when the longitudinal screw sliding assembly 7 leaves the pressing and cutting position to a safe position, the staff can take away the pre-separated block-shaped tea cake; if the staff wants to press and cut tea cakes of different sizes, they can take a tool for tightening the hexagonal bolts, reach into the right side of the device to tighten the hexagonal bolts 2-5 of the cutter spacing adjustment mechanism 2, and adjust the distance 5 between the tool holder assemblies, so that it can be suitable for tea cakes of different sizes. The data acquisition card is connected to the vibration sensor 11-1 and the acoustic emission sensor 11-2 through the serial port. After data acquisition, the collected data can be saved in the SD card in real time, and then the integrated display screen 12 can read the data in the SD card, and then display the data predicted by the random forest regression model in real time through the components. The random forest regression model can be deployed in the processor of the integrated display screen 12. In addition, the staff can also visualize the life prediction of the six cutters 5-2 through the integrated display screen 12. When the life of the six cutters 5-2 reaches less than 15%, new cutters 5-2 can be replaced to consider the cutting efficiency. The entire process of cutting is fast and efficient, and there is almost no noise during the cutting process. The device of the present invention has a simple and intelligent structure, a compact size, is quiet, and has high efficiency.

[0061] The device of the present invention has a simple structure, compact size and high efficiency. It can not only predict and display the life of the tool in real time through an artificial intelligence algorithm, but also adjust the distance between the six cutters equidistantly through an adjustment mechanism, that is, the device can be suitable for pre-separation operations of targets of different sizes.

[0062] The specific implementation modes of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
