The feeding barrel 42 is located above the fixed box 41, and a mounting frame 421 is fixedly connected to the bottom of the feeding barrel 42, and the mounting frame 421 is fixedly mounted on the frame 11 through a support rod. The movable seat 43 is located on the fixed box 41 and slides along the length direction of the fixed box 41. A discharge hole 431 is provided in the movable seat 43, and a discharge plate 432 slides relatively in the movable seat 43. The discharge plate 432 is arranged at an angle, and the discharge plate 432 slides in the discharge hole 431. A control component 5 for controlling the sliding of the discharge plate 432 is arranged in the movable seat 43. The control component 5 includes a control rope 51, a control ball 52 and a control spring 53. Two control ropes 51 are arranged, one end of the control rope 51 extends out of the fixed box 41, and the other end is connected to the discharge plate 432. The control ball 52 is fixedly connected to the end of the control rope 51 extending out of the fixed box 41. An auxiliary groove 433 is provided on the hole wall of the discharge hole 431. The side of the discharge plate 432 away from the control rope 51 slides in the auxiliary groove 433. One end of the control spring 53 is fixedly connected to the discharge plate 432, and the other end is connected to the bottom of the auxiliary groove 433. Under natural circumstances, the control spring 53 applies tension to the discharge plate 432. The feeding cylinder 44 is installed on the fixed box 41, and the piston rod of the feeding cylinder 44 is fixedly connected to the movable seat 43. When loading is required, the operator delivers the raw material to the discharge hole 431 through the loading barrel 42, and the discharge plate 432 can support the raw material in the discharge hole 431, and then drives the loading cylinder 44 to drive the movement of the movable seat 43, so that the movable seat 43 moves toward the pressing mold 12; when the movable seat 43 moves to the top of the pressing mold 12, the movable seat 43 drives the control rope 51 to move, and the control rope 51 drives the control ball 52 to move, and the control ball 52 abuts against the fixed box 41.

At this time, the control spring 53 applies a force to the discharge plate 432, so that the discharge plate 432 returns to the initial position, which is convenient for the discharge plate 432 to support the raw material.

[0035] like Figure 5As shown, a pressing groove 121 is provided in the pressing mold 12, and the protective paper box raw material is placed in the pressing groove 121. A supporting mold 122 is relatively slidable in the pressing mold 12, and the supporting mold 122 is located in the pressing groove 121 and slides, and the sliding direction of the supporting mold 122 is the vertical direction; a supporting cylinder 112 is installed in the frame 11, and the piston rod of the supporting cylinder 112 is fixedly connected to the supporting mold 122. After the raw material in the pressing groove 121 is pressed, the operator drives the support mold 122 to move through the supporting cylinder 112, and the supporting mold 122 can push out the cake-shaped raw material in the pressing groove 121, which is convenient for subsequent operations on the raw material.

[0036] like Figure 2 and 5 As shown, the pressing device 1 further includes a hydraulic cylinder 13, which is mounted on the frame 11 and located above the pressing die 12.

When it is necessary to press the raw materials in the pressing groove 121, the operator can drive the hydraulic cylinder 13 so that the piston rod of the hydraulic cylinder 13 drives the movement of the pressing head. The guide plate 113 can limit the movement of the piston rod of the hydraulic cylinder 13, thereby limiting the movement of the pressing head. The pressing head can apply force to the raw materials in the pressing groove 121 to press the raw materials into a cake shape, thereby achieving the pressing of the raw materials.

[0037] like Figure 2 , 3 As shown in FIG. 4 , a storage box 115 is fixedly mounted on the frame 11, and the protective paper is placed in the storage box 115; the pressing device 1 also includes a rotating frame 14, which is rotatably connected to the frame 11, and the rotating frame 14 can be rotated to the top of the pressing mold 12.

A rotating motor 111 is mounted on the frame 11, and a rotating rod 142 is fixedly connected to the rotating frame 14, and the output shaft of the rotating motor 111 is fixedly connected to the rotating rod 142. A blanking hole 143 is opened on the rotating frame 14, and a clearance groove 434 is opened on the moving seat 43, and the clearance groove 434 is for the rotating frame 14 to be placed. When loading is required, the suction pipe 141 absorbs the protective paper, and then the rotating motor 111 drives the rotating frame 14 to rotate to the top of the pressing mold 12, and then the movable seat 43 also moves to the top of the pressing mold 12. At this time, the rotating frame 14 is located in the make way groove 434, and the discharge plate 432 moves away from the movable seat 43. The raw material in the movable seat 43 falls onto the protective paper through the drop hole 143, and the protective paper falls into the pressing groove 121 under the gravity of the raw material, which is convenient for the pressing work of the protective paper and the raw material.

[0038] like Figure 2 , 3 As shown in FIG. 5 , two arc-shaped rods 123 are relatively slidable in the pressing mold 12. The two arc-shaped rods 123 are close to or away from each other. A sliding groove 124 is provided on the groove wall of the pressing groove 121. The arc-shaped rod 123 is located in the sliding groove 124 and slides.

One end of the sliding spring 66 is fixedly connected to the groove wall of the sliding groove 124, and the other end is fixedly connected to the follower rod 62. Under natural circumstances, the sliding spring 66 applies a pulling force to the arc rod 123, so that the arc rod 123 moves away from the groove wall of the pressing groove 121. When the protective paper and the raw material fall into the pressing groove 121, the operator drives the hydraulic cylinder 13 to press the raw material.

At this time, the pressing head contacts the protective paper, and the arc rod 123 returns to the sliding groove 124, reducing the possibility of collision between the pressing head and the arc rod 123, which is convenient for the pressing of the protective paper and the raw material.

[0039] like Figure 1 As shown, a conveying plate 125 is fixedly connected to the pressing die 12, and the conveying plate 125 and the fixing box 41 are integrally formed.
