[0021] like Figure 1-4 As shown, a back-opening and flattening device includes a frame 1 and a conveying chain 2 arranged on the top of the frame 1. The conveying chains 2 are symmetrically arranged on the left and right, and the left and right conveying chains 2 are fixedly connected at the same position by spikes, so that the left and right conveying chains 2 synchronously push the spikes to move, and the outer sides of the conveying chains 2 on each side are respectively provided with horizontal guide plates 10, which are supported and limited by the guide plates 10 so that the chicken back can only move between the conveying chains 2. The frame 1 at the conveying end of the conveying chain 2 is provided with an upper pressing roller 3 and a lower pressing roller 4 arranged up and down, and the upper pressing roller There is a gap between the upper and lower pressure rollers 3 and 4, and a vertically rotating cutting knife 5 is also arranged between the left and right conveying chains 2 at the front end of the lower pressure roller 4. The conveying chain 2, the upper pressure roller 3, the lower pressure roller 4 and the cutting knife 5 are driven by motors respectively, and the two ends of the rotating shafts of the conveying chain 2 sprocket, the upper pressure roller 3, the lower pressure roller 4 and the cutting knife 5 are fixedly mounted on the frame 1 through bearing seats 12 with bearings respectively, such as the currently commonly used driving structure, which can be driven by a motor, a belt and a pulley for operation, and the bottom support of the frame 1 is provided with a plurality of universal wheels 13 for easy movement.

[0022] In order to play a guiding role, the frame 1 on the left and right sides of the cutting knife 5 is fixed with symmetrical guiding curved rods 9, and the front ends of the two guiding curved rods 9 form a trumpet-shaped opening structure. The frame 1 between the lower pressure roller 4 and the cutting knife 5 is fixed with an expansion flattening triangle plate 6, and the tip of the expansion flattening triangle plate 6 is provided with a knife slit, which is used to pass through the cutting knife 5. The chicken back behind the cut passes through the tip of the expansion flattening triangle plate 6 under the pushing action of the two conveying chains 2 and the spikes, that is, the abdomen of the chicken back is penetrated by the tip of the expansion flattening triangle plate 6. As the chicken back continues to move, it is gradually stretched along the incision part by the expansion flattening triangle plate 6, and until it is fully expanded to the lower surface of the end of the expansion flattening triangle plate 6, it is convenient to enter the gap between the upper pressure roller 3 and the lower pressure roller 4, which is convenient for further flattening.

[0023] In order to improve the flattening effect and increase the friction force at the same time, the periphery of the upper pressing roller 3 and the lower pressing roller 4 is provided with a plurality of raised strips 7 protruding from the roller body, the width of the raised strips 7 of the lower pressing roller 4 is greater than the width of the raised strips 7 of the upper pressing roller 3, and the periphery center of the lower pressing roller 4 is provided with an annular groove structure 8 which is in the same straight line as the cutting knife 5, and the annular groove structure 8 can pass through the chicken neck to prevent the chicken neck from being crushed flat; the frame 1 at one end of the upper pressing roller 3 and the lower pressing roller 4 is provided with a downward slanting lower hopper 11 for convenient material receiving.

[0024] The working principle of the utility model is as follows: first, the motor drives the conveyor chain 2 forward, and the chicken back is conveyed forward to the blade position for cutting through the conveyor chain 2 with spikes. The guide plates 10 and the guide curved rods 9 on both sides of the conveyor chain 2 prevent the chicken back from being cut off-center. After opening the back, the chicken back enters the expansion and flattening triangle plate 6, and the opening is expanded from a small opening to a large opening. As the conveyor chain 2 moves forward, the chicken back enters the bottom of the expansion and flattening triangle plate 6 to be flattened. The flattened chicken back enters between the upper pressing roller 3 and the lower pressing roller 4 to be further flattened, and the back-opening and flattening process of the chicken back is completed.

[0025] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
