DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0020] The accompanying drawings are specific embodiments of the present invention. Figures 1 to 6 As shown, the tofu cutting device includes a PLC control system and a frame 1. The entire present invention is controlled and operated by the PLC control system, including the start-up and operation of various cylinders and motors.

[0021] A conveyor belt 2 is installed on the frame 1, and the conveyor belt 2 is driven to rotate by a motor. The width of the conveyor belt 2 is greater than the width of the tofu; a baffle 3 is installed on both sides above the conveyor belt 2, and the baffle 3 is arranged along the length direction of the conveyor belt 2. The distance between the two baffles 3 can be adjusted. The adjustment method is the existing technology and will not be repeated. The function of the baffle 3 is to prevent the cut tofu blocks from scattering and rolling everywhere, so the height of the baffle 3 can only be slightly lower than the thickness of the tofu, or higher than the thickness of the tofu; the conveyor belt 2 is composed of a plurality of wide bands 201 arranged at intervals, and the two wide bands 201 located on the outer side can be wider than the other wide bands 201 to facilitate the movement of the baffle 3; a cutting bracket 4 is installed on the frame 1, and the cutting bracket 4 includes a part located above and a part located below the conveyor belt 2. A cutting lifting cylinder 5 is installed on the upper part, and the output end of the cutting lifting cylinder 5 faces downward. A fixed rod 6 is fixedly installed on the output end of the cutting lifting cylinder 5, and a lifting cover 7 is put on the fixed rod 6. That is to say, the lifting cover 7 can move up and down on the fixed rod 6. The cross section of the fixed rod 6 is preferably polygonal or elliptical, and the lifting cover 7 has a through hole 8 of the same shape, so that the lifting cover 7 can only move up and down but cannot rotate. After the lifting cover 7 falls, it is located within the shielding range of the baffle 3; the lower end and the entrance end of the lifting cover 7 are both open structures, and a plurality of horizontal transverse cutting knives 9 are installed at its entrance end. The length direction of the transverse cutting knives 9 is perpendicular to the conveyor belt 2. A transverse plate 10 is also fixed at the upper end of its entrance end. The transverse plate 10 has a plurality of notches 1001, and each notch 1001 corresponds to a spacing of a wide band 201 below; the cutting bracket 4 also includes a horizontal plate 11 located below the conveyor belt 2, and the horizontal plate 11 has a plurality of long holes 1101. The long holes 1101, the gaps between the wide bands 201 and the notches 1001 are in a straight line, and the longitudinal cutting knife 24 passes through the above three points from the bottom of the horizontal plate 11 and is fixed to the upper end of the cutting bracket 4.

[0022] Since the tofu passes through the transverse cutting knife 9 and the longitudinal cutting knife 24 during the working process, the transverse cutting knife 9 and the longitudinal cutting knife 24 can be narrower, and even a cutting line can be used.

[0023] Two comb plates 12 are fixed in the lifting cover 7. The two comb plates 12 are arranged along the length direction of the conveyor belt 2. The distance between the two comb plates 12 is slightly larger than the width of the tofu. A horizontal grid plate 13 is also fixed between the two comb plates 12. The gaps of the horizontal grid plates 13 are aligned with the gaps of the comb plates 12. That is to say, both ends of each strip of the horizontal grid plate 13 are fixed on the comb teeth of the comb plate 12. The height of the water grid plate is slightly larger than the thickness of the tofu. The fixing rod 6 is inserted into the lifting cover 7 and fixed. A knife holder plate 14 is installed, and several knife holders 15 are installed on the knife holder plate 14. The plane where the knife holders 15 are located is perpendicular to the conveyor belt 2. A vertical cutting knife 16 is installed on each knife holder 15. The width of the vertical cutting knife 16 can be wider, slightly thinner than the thickness of tofu, or larger than the thickness of tofu. The length of the knife holder 15 is relatively long, and its two ends can extend from the two comb plates 12 and be located between the comb plates 12 and the lifting cover 7, and the vertical cutting knife 16 can pass through the horizontal grid plate 13.

[0024] A booster bracket 17 is installed on the frame 1, and the booster bracket 17 is located at the entrance side of the lifting cover 7, that is, the tofu first passes through the booster bracket 17 and then enters the lifting cover 7; a booster lifting cylinder 18 is installed on the booster bracket 17, and the output end of the booster lifting cylinder 18 faces downward. A booster device is installed at the output end of the booster lifting cylinder 18. There are two implementation methods of the booster device: Embodiment 1: A booster cylinder 19 is fixed at the output end of the booster lifting cylinder 18 , the booster cylinder 19 is parallel to the conveyor belt 2 , and its output end faces the lifting cover 7 , and a booster plate 20 is installed at the output end of the booster cylinder 19 .

[0025] Embodiment 2: A mounting plate 21 is fixedly mounted at the output end of the boost lifting cylinder 18, and a boost conveyor belt 22 is mounted on the lower surface of the mounting plate 21. The boost conveyor belt 22 is driven to rotate by a boost motor 23. The boost motor 23 is a forward and reverse motor, which can be mounted on the mounting plate 21; a boost plate 20 is mounted on the boost conveyor belt 22. The installation of the boost plate 20 belongs to the prior art and will not be described in detail.

[0026] The working process is as follows: set various parameters on the PLC control system, adjust the position of the baffle 3, make the distance between the two baffles 3 larger than the width of the lifting cover 7, that is, let the lifting cover 7 fall into the shielding range of the baffle 3, and lower the lifting cover 7 onto the conveyor belt 2. The lifting cover 7 lightly presses on the conveyor belt 2 and cannot affect the transmission of the conveyor belt 2. However, the vertical cutting knife 16 is still in a suspended state at this time, that is, the output end of the cutting lifting cylinder 5 is only partially extended at this time; start the PLC control system, put the tofu on the conveyor belt 2, and when the tofu reaches the booster bracket 17, The booster lifting cylinder 18 is started, driving the booster plate 20 to descend, and the booster plate 20 pushes the tofu forward. The tofu is cut horizontally and vertically when passing through the transverse cutting knife 9 and the longitudinal cutting knife 24. When the tofu has completely passed through the transverse cutting knife 9 and the longitudinal cutting knife 24, the booster plate 20 is withdrawn, and the booster lifting cylinder 18 also lifts the booster device to the original position again, waiting for the next boost; when the tofu has completely entered the lifting cover 7, the conveyor belt 2 stops conveying. At this time, the tofu has completely passed through the longitudinal cutting knife 24 and the transverse cutting knife 9, especially the transverse cutting knife 9 has been completely exposed (such as Figure 6 and Figure 7 As shown, the strips of the horizontal grid plate above the horizontal cutting knife, that is, the lowest part in the figure, are wider than the strips at other positions), the cutting lifting cylinder 5 is started again, driving the vertical cutting knife 16 to cut the tofu vertically downward, so that the tofu is cut into several tofu blocks, and then the cutting lifting cylinder 5 is retracted, first retracting the vertical cutting knife 16. At this time, if there are tofu blocks stuck to the vertical cutting knife 16, the horizontal grid plate 13 can block the tofu blocks, and when the knife holder 15 rises to the point where it can no longer rise, the knife holder 15 rises with the lifting cover 7 again, exposing all the tofu blocks, and the conveyor belt 2 is started again to transport the tofu blocks forward, and the above actions are repeated for the next tofu block.
