[0051] The automatic identification mechanism 500 can automatically identify the thickness and width of the chopping board 400, so that the control processor 300 adjusts the downward movement distance of the plurality of pressing progressive rollers 601, the coarse polishing belt wheel 603, and the fine polishing belt wheel 604, and the inward movement distance of the limiting side polishing mechanism 700 and the side polishing belt wheel 703;

[0052] Among them, a progressive top polishing mechanism 600 for progressively polishing the polishing table board 400 is provided at the top of the conveying roller mechanism 200. The progressive top polishing mechanism 600 includes a number of pressing progressive rollers 601 that are consistent with the conveying direction and speed of the conveying roller mechanism 200. Vertical buffer rods 602 are provided at the tops of the number of pressing progressive rollers 601.

[0055] The limit side polishing mechanism 700 further includes connecting rods A704 symmetrically distributed inside the bottom frame 100. A number of pressing progressive rollers 601 are rotatably connected to the top of the connecting rods A704. A number of longitudinal buffer rods 702 are fixedly connected to the sides of the connecting rods A704. One end of the number of longitudinal buffer rods 702 far from the connecting rods A704 is fixedly connected to a connecting rod B705 together. Symmetrically fixed to the bottom of the connecting rod B705 are connecting plates 706. Fixedly connected between two opposite connecting plates 706 is a horizontal electro-hydraulic push rod 707 connected to the control processor 300. After the automatic recognition mechanism 500 automatically recognizes the width of the cutting board 400, the horizontal electro-hydraulic push rod 707 shortens the remaining distance according to the initial distance between a number of limit centering rollers 701 and side polishing sand wheels 703 on both sides, so that a number of pressing progressive rollers 601 limit the cutting board 400 inward and center the cutting board 400, and enable the side polishing sand wheels 703 to contact the side of the cutting board 400;

[0056] Fixed to the outside of the front side connecting plate 706 is a U-shaped mounting frame 708 slidably connected to the bottom side of the bottom frame 100. Fixed to the inside of the mounting frame 708 are a lower limit sleeve 709 and an upper limit sleeve 710. Mounted on the bottom side of the mounting frame 708 is a driving motor B711.

When the worm gear 715 and the cam 716 rotate, the driving rod 721 can be driven to move up and down through the contact wheel 722, so as to drive the rotating side polishing sand wheel 703 to move up and down and uniformly polish the side of the cutting board 400.

[0058] Working principle of the present invention: The specific working steps for comprehensively polishing the chopping board 400 of the present invention are as follows:

[0059] S1. Front placement: First, place the chopping board 400 vertically on the conveying roller mechanism 200 and ensure that the front side of the chopping board 400 faces upward, as Figure 1 shown;

[0060] S2. Dimension recognition: First, ensure that the preset module in the automatic recognition mechanism 500 has pre-stored the installation height G1 of the camera 540 and calculated the width ratio K at the shooting height G2, N and ensure that the electric telescopic rod 530 is in the shortest state (i.e., the camera 540 maintains the pre-stored installation height G1 state). Obtain the area board image of the chopping board 400 through the camera 540. The image processing module receives the area board image information of the chopping board 400 obtained by the camera 540 and processes it to obtain the shooting height G2 and the pixel width K1 of the board surface image of the chopping board 400 at the shooting height G2. At the same time, the preset module calculates the actual thickness H of the camera 540. Subsequently, the matching module matches the associated width ratio K at the shooting height G2, N and calculates the actual width K2 of the chopping board 400 according to the obtained pixel width G2 of the board surface image. In this way, the automatic recognition of the thickness and width of the chopping board 400 can be realized;

[0061] S3. Position adjustment: According to the thickness and width of the chopping board 400 recognized by the automatic recognition mechanism 500, control the processor 300 to adjust the shortening of the electro-hydraulic push rod group 605 in the progressive top polishing mechanism 600, so that it shortens the remaining distance according to the initial distance of several pressing progressive rollers 601, rough polishing sand belt wheels 603, and fine polishing sand belt wheels 604, so that several pressing progressive rollers 601 press down on the chopping board 400 and cooperate with the conveying roller mechanism 200 to convey and progress the chopping board 400, and make the rough polishing sand belt wheel 603 and the fine polishing sand belt wheel 604 able to contact the front or back surface of the chopping board 400. At the same time, control the processor 300 to adjust the shortening of the horizontal electro-hydraulic push rod 707 in the limit side polishing mechanism 700, so that it shortens the remaining distance according to the initial distance of several limit centering rollers 701 and side polishing sand belt wheels 703 on both sides, so that several pressing progressive rollers 601 limit the chopping board 400 inward and center and limit the chopping board 400, and make the side polishing sand belt wheel 703 able to contact the side surface of the chopping board 400. In this way, the effects of progressive top polishing and limit side polishing of the chopping board 400 can be realized;

[0062] S4, single polishing: The chopping board 400 is pressed and advanced by the running conveying roller mechanism 200 and a plurality of pressing and advancing rollers 601. During the pressing and advancing process of the chopping board 400, the limit centering rollers 701 on both sides limit and center it. At the same time, the side polishing abrasive belt wheels 703 on both sides polish both sides of the chopping board 400, and the coarse polishing abrasive belt wheels 603 and the fine polishing abrasive belt wheels 604 on the top side perform coarse polishing and fine polishing on the front side of the chopping board 400. In this way, the front and both side surfaces of the chopping board 400 can be polished.

[0063] When the side polishing abrasive belt wheels 703 on both sides polish the two sides of the chopping board 400, the driving motor B711 is started, so that the worm 712 drives the side polishing abrasive belt wheels 703 to rotate in the direction opposite to the forward direction of the chopping board 400 through the cross connecting rod 713 and the cross connecting cylinder 714, and at the same time, the worm 712 drives the cam 716 to rotate through the worm wheel 715, and the rotation of the cam 716 can drive the driving rod 721 to move up and down through the abutment wheel 722, and the driving rod 721 that moves up and down can drive the cross connecting cylinder 714 to move up and down through the guide groove arm 719, so that the rotating side polishing abrasive belt wheels 703 move up and down to evenly polish the side of the chopping board 400;

[0064] When the coarse polishing abrasive belt wheel 603 and the fine polishing abrasive belt wheel 604 on the top side perform coarse polishing and fine polishing on the front side of the chopping board 400, the driving motor A607 is started to make the coarse polishing abrasive belt wheel 603 and the fine polishing abrasive belt wheel 604 rotate in the direction opposite to the forward direction of the chopping board 400, thereby achieving coarse polishing and fine polishing on the front and back sides of the chopping board 400;

[0065] S5, position restoration: after a single polishing is completed, the electro-hydraulic push rod group 605 in the progressive top polishing mechanism 600 is reset and the horizontal electro-hydraulic push rod 707 in the position-limiting side polishing mechanism 700 is reset by controlling the processor 300, so that the positions of the progressive top polishing mechanism 600 and the position-limiting side polishing mechanism 700 are restored;

[0066] S6, placing the back side: placing the once-polished chopping board 400 horizontally on the conveying roller mechanism 200, and ensuring that the back side of the chopping board 400 faces upward;

[0067] S7, repeat S2-S5, and then repeat S2-S5 to complete the polishing of the back side and the other two side surfaces of the chopping board 400, so that the chopping board 400 can be fully polished.

[0068] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
