DETAILED DESCRIPTION

[0017] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0018] Embodiment 1 The present invention discloses a Figure 1-3 The food cutting equipment shown is used for cutting high sugar and sticky cake-shaped foods such as fruit leather, sticky cakes, and biscuits. The equipment includes a frame 1, a conveyor belt drive motor 4, a roller drive motor 8, a transmission mechanism 7, and a tightening mechanism 12 are installed on the side of the frame, and a plurality of conveyor rollers parallel to each other are installed above the frame. The plurality of conveyor rollers jointly support the conveyor belt 2 for circulating motion, and a first mold roller 5 and a second mold roller parallel to each other are arranged above the conveyor belt. Among them, the active conveyor roller 3 is directly connected to the conveyor belt drive motor 4 through a reducer, and two passive conveyor rollers 13 are installed on the inner side of the conveyor belt 2, and are arranged symmetrically with the two mold rollers about the conveyor belt 2. Each passive conveyor roller 13 is connected to a tightening mechanism 12, and the passive conveyor roller 13 is driven to move up and down by the tightening mechanism 12, so that the conveyor belt 2 is in contact with or separated from the mold roller.

[0019] The first mold roller 5 and the second mold roller 6 are both cylindrical structures. Each group of mold rollers is radially arranged with multiple strip-shaped cutting knives 9 around the axis. The blade of the cutting knife 9 is located at the end away from the mold roller. Multiple cutting grooves 10 are sequentially arranged on the blade of the cutting knife 9 along the axis direction of the mold roller. Two support rods 14 are arranged above the conveyor belt 2. The axis direction of the support rods 14 is arranged parallel to the axis direction of the mold roller. The support rods 14 are located on the discharge side of the mold roller. Multiple mold guide strips 11 are arranged along the axis direction of the support rods 14. Each mold guide strip is configured corresponding to the cutting groove 10. The cutting grooves 10 and the configured mold guide strips 11 on the first mold roller 5 and the second mold roller 6 are arranged alternately. That is, the cutting grooves 10 on the two mold rollers are not on the same conveying straight line. In this way, the food that has not been cut by the cutting knife (9) at the cutting groove (10) of the previous mold roller can be cut by the cutting knife (9) of the next mold roller.

[0020] The mold guide bar 11 is an arc-shaped structure, and the size of the arc-shaped structure matches the outer size of the mold roller. In order to ensure the same cutting effect of the two mold rollers, the two mold rollers need to be set to have the same rotation speed, which is achieved through the roller drive motor 8 and the transmission mechanism 7 composed of a reducer, belts, pulleys and gears.

[0021] Embodiment 2 This embodiment discloses a method for cutting food using the above-mentioned food cutting device, which is specifically as follows: The food is conveyed to the first mold roller 5 via the conveyor belt 2. The first mold roller 5 rotates counterclockwise, driving the cutting knife 9 on its surface to cut the food longitudinally. When the cut food is stuck in and adheres to the area between two adjacent cutting knives 9, as the food moves along the conveyor belt, at the discharge end of the first mold roller 5, the mold guide bar 11 is inserted into the cutting groove 10 to guide out the stuck and adhered food; at this time, the area of ​​the food located in the cutting groove 10 is not cut, so the food is conveyed forward along the conveyor belt to the second mold roller 6. The second mold roller 6 drives the cutting knife 9 to rotate, cuts the part of the food that has not been cut at the cutting groove of the previous mold roller, and realizes the longitudinal complete cutting of the food. At the same time, the mold guide bar 11 at the second mold roller 6 again guides out the food adhered in the area between the two adjacent cutting knives of the second mold roller 6.

[0022] Embodiment 3 In this embodiment, the cutting blade 9 is designed to be in the shape of a curve extending along the axis of the mold roller, so that small pieces of food in a patterned shape can be cut out.

[0023] Embodiment 4 In this embodiment, the mold roller can be provided with three, four or more grooves, so that smaller block foods can be cut out in sequence. If the grooves on a mold roller are provided too densely, adhesion phenomenon is still likely to occur, so a plurality of mold rollers are used in combination.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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 protection scope of the present invention.
