When the clamping component operates, the clamping component can clamp the rice bag.

[0034] Please refer to Figure 4 As shown in the figure, the clamping component includes a cross bar 9, a guide plate 91, a return spring 92, and a guide roller 93. The cross bars 9 are symmetrically and fixedly connected between the upper parts of the front and rear side surfaces of the box body 1 on the left and right. Two guide plates 91 are slidably sleeved between the left and right cross bars 9. The upper parts of the two guide plates 91 are inclined. When the rice bag contacts the inclined surface of the guide plate 91, the guide plate 91 can guide the rice bag. The lower parts of the front and rear guide plates 91 are rotatably penetrated by the guide rollers 93. When the guide rollers 93 contact the rice bag, the guide rollers 93 can clamp the opening of the rice bag. Between the mutually separated sides of the front and rear guide plates 91 and the front and rear side surfaces of the box body 1 respectively, return springs 92 are symmetrically connected on the left and right. The return springs 92 are sleeved on the cross bars 9.

[0035] Please refer to Figures 6 - 8 As shown, the discharging assembly includes a material guiding plate 10, a discharging plate 101, a rotating rod 102, a one-way ratchet 103, a ratchet bar 104, a disc 105 and a connecting rod 106. The discharging plate 101 is rotatably connected to the left side of the top of the placing plate 4. When the discharging plate 101 swings upward, the discharging plate 101 can push out the rice bag after the rice is discharged. An outlet is opened on the left side of the box body 1. The material guiding plate 10 is fixedly connected to the lower left side of the left side of the box body 1. The material guiding plate 10 is located on the left side of the placing plate 4. The material guiding plate 10 can guide the rice bag. The rotating rod 102 is rotatably connected to the left side of the front surface of the placing plate 4. The front end of the rotating rod 102 is fixedly connected to the one-way ratchet 103. The rear end of the rotating rod 102 is fixedly connected to the disc 105. The eccentric position on the rear side of the disc 105 is rotatably connected to the connecting rod 106. The tail end of the connecting rod 106 is rotatably connected to the left side of the front surface of the discharging plate 101. The ratchet bar 104 is fixedly connected to the lower left side of the front inner surface of the box body 1. The ratchet bar 104 meshes with the one-way ratchet 103. When the one-way ratchet 103 resets, the ratchet bar 104 can drive the one-way ratchet 103 to rotate forward one circle.

[0036] First, place a bag of rice vertically into the box body 1. The rice bag moves downward and contacts the guide plate 91. The rice bag drives the guide plate 91 to move in a direction away from each other, and the return spring 92 is compressed. The guide plate 91 drives the guide rollers 93 on the front and rear sides to move in a direction away from each other. The rice bag continues to move downward and contacts the guide rollers 93. The guide rollers 93 guide the rice bag. The rice bag moves downward and contacts the top of the placement plate 4. At this time, the rice bag stops expanding the guide plate 91. Due to the action of the return spring 92, the guide plates 91 on the front and rear sides move in a direction close to each other, driving the guide rollers 93 on the front and rear sides to move in a direction close to each other. The guide rollers 93 on the front and rear sides clamp the upper part of the rice bag, making the upper part of the rice bag in a taut state. Subsequently, start the stepping motor 74 to drive the right double screw rod 7 to rotate. The rotation of the right double screw rod 7 drives the left double screw rod 7 to rotate through the synchronous belt assembly. The rotation of the double screw rods 7 on the left and right sides drives the clamping plates 5 on the front and rear sides to move in a direction close to each other. The clamping plates 5 on the front and rear sides contact the rice bag, thus clamping and fixing the rice bag. Turn off the stepping motor 74, start the rodless cylinder 8 to drive the movable seats 81 on the front and rear sides to move in a direction close to each other. The movable seats 81 on the front and rear sides drive the U-shaped rods 82 on the front and rear sides to move in a direction close to each other through the compression springs 84. The U-shaped rods 82 drive the cutting knives 83 on the front and rear sides to move in a direction close to each other. At the same time, the movable seat 81 also drives the contact blocks 85 on the front and rear sides to move in a direction close to each other. The contact blocks 85 on the front and rear sides contact each other, which makes the contact blocks 85 slide outward on the movable seat 81. The sliding of the contact blocks 85 drives the pull wire 86 to move. The movement of the pull wire 86 drives the U-shaped rod 82 to slide inward, and the compression spring 84 is compressed. The sliding of the U-shaped rod 82 drives the cutting knife 83 to continue sliding inward to cut the rice bag, thus completing the bag cutting process. Subsequently, start the rodless cylinder 8 to drive the movable seats 81 on the front and rear sides to move outward and reset. The reset of the movable seat 81 drives the contact blocks 85 to reset. The contact blocks 85 on the front and rear sides are separated from each other. Due to the action of the compression spring 84, the U-shaped rod 82 drives the cutting knife 83 to slide in a direction away from each other and reset. At the same time, the U-shaped rod 82 drives the contact block 85 to slide and reset through the pull wire 86. Then start the servo motor 6 to drive the rotating shaft 3 to rotate forward. The forward rotation of the rotating shaft 3 drives the placement plate 4 to rotate forward. The forward rotation of the placement plate 4 drives the clamping plate 5 to rotate forward. The forward rotation of the clamping plate 5 drives the rice bag to rotate forward. And the placement plate 4 also drives the one-way ratchet 103 to swing to the right through the rotating rod 102. The swinging of the one-way ratchet 103 slides on the ratchet bar 104. The one-way ratchet 103 continues to swing and is separated from the ratchet bar 104. When the rice bag rotates 180 degrees, turn off the servo motor 6. The rice in the rice bag falls downward into the lower part of the box body 1 and is discharged, and the discharged rice can be collected, so that there is no need to manually pour out the rice subsequently, thereby improving work efficiency. When all the rice is discharged, start the servo motor 6 to drive the rotating shaft 3 to rotate reversely, so that the placement plate 4 rotates reversely and resets. The placement plate 4 drives the one-way ratchet 103 to swing to the left through the rotating shaft 3 and engage with the ratchet bar 104. The ratchet bar 104 drives the one-way ratchet 103 to rotate forward one circle.The one-way ratchet 103 drives the disc 105 to rotate forward through the rotating shaft 3. When the disc 105 rotates forward one circle, it drives the discharge plate 101 to swing up and down once through the connecting rod 106. When the discharge plate 101 swings upward, the rice discharged from the rice is pushed onto the guide plate 10, and the rice bag falls from the guide plate 10. Repeating this process can continuously complete the bag cutting process for the rice.

[0037] Please refer to Figure 9 and Figure 10 As shown in the figure, it further includes a fixing component installed between the box body 1 and the clamping plate 5. The fixing component includes an arc-shaped plate 11, a single-rod piston cylinder I 111, a hose 112, a single-rod piston cylinder II 113, a support spring 114, a sliding rod 115, a clamping frame 116 and a swing seat 117. The clamping frames 116 are rotatably connected to the front and rear clamping plates 5 at equal intervals. When the clamping frame 116 swings and contacts the rice bag, the clamping frame 116 can hook the rice bag. Swing seats 117 are fixedly sleeved in the middle of the front and rear clamping frames 116. A linear hole is opened on the inner side of the swing seat 117. The sliding rod 115 is vertically slidably connected to the side of the front and rear clamping plates 5 away from each other. The sliding rod 115 is slidably connected to the linear hole of the swing seat 117. When the sliding rod 115 moves, the sliding rod 115 can drive the swing seat 117 to swing. The single-rod piston cylinder II 113 is fixedly connected to the side of the front and rear clamping plates 5 away from each other. The piston rods of the front and rear single-rod piston cylinders II 113 are respectively fixedly connected to the bottom ends of the front and rear sliding rods 115. A support spring 114 is connected between the upper part of the piston rod of the front and rear single-rod piston cylinders II 113 and the outer top of the cylinder body. The bottom of the single-rod piston cylinder II 113 is communicated with the hose 112. The single-rod piston cylinder I 111 is symmetrically and fixedly connected to the front and rear of the bottom of the rotating shaft 3. The top of the single-rod piston cylinder I 111 is fixedly connected and communicated with the tail end of the hose 112. The arc-shaped plates 11 are fixedly connected to the lower parts of the front and rear inner sides of the box body 1. The inner side of the arc-shaped plate 11 contacts the end of the piston rod of the single-rod piston cylinder I 111, and the arc-shaped plate 11 can drive the piston rod of the single-rod piston cylinder I 111 to move inward.

[0038] When the rotating shaft 3 rotates forward to drive the placing plate 4 to rotate forward, the forward rotation of the rotating shaft 3 also drives the single-rod piston cylinder I 111 to rotate forward. The piston rod of the single-rod piston cylinder I 111 slides along the inner wall of the arc-shaped plate 11, and the arc-shaped plate 11 drives the piston rod of the single-rod piston cylinder I 111 to move inward, so that the liquid in the single-rod piston cylinder I 111 is discharged into the single-rod piston cylinder II 113 through the hose 112. As the liquid is discharged, the piston rod of the single-rod piston cylinder II 113 moves upward to drive the sliding rod 115 to move upward, the supporting spring 114 is compressed, the sliding rod 115 moves upward to drive the swing seat 117 to swing upward, the swing seat 117 swings upward to drive the clamping frame 116 to swing downward, and the clamping frame 116 swings downward and is clamped into the rice bag, thus hooking and fixing the rice bag. Subsequently, the rice bag rotates 180 degrees forward to pour out the rice. When the rotating shaft 3 drives the placing plate 4 to rotate reversely and reset, the rotating shaft 3 drives the single-rod piston cylinder I 111 to rotate reversely. The piston rod of the single-rod piston cylinder I 111 stops being limited by the arc-shaped plate 11. Due to the action of the supporting spring 114, the piston rod of the single-rod piston cylinder II 113 moves downward to reset and push the liquid back into the single-rod piston cylinder I 111 through the hose 112. At the same time, the piston rod of the single-rod piston cylinder II 113 drives the sliding rod 115 to move downward, the sliding rod 115 moves downward to drive the swing seat 117 to swing downward and reset, the swing seat 117 drives the clamping frame 116 to swing upward and reset, and the clamping frame 116 resets to release the rice bag. Subsequently, the discharge plate 101 pushes the rice bag out of the placing plate 4. In this way, it is possible to prevent the rice bag from falling together with the rice during the rice pouring process, thus ensuring the complete separation of the rice bag and the rice.

[0039] Please refer to Figure 11 As shown in the figure, it further includes an observation window 12. The left and right sides of the lower part of the front side of the box body 1 are symmetrically and fixedly penetrated with the observation window 12.

[0040] Please refer to Figure 12 As shown in the figure, it further includes a buffer plate 13 and a buffer spring 131. The buffer plate 13 is symmetrically and slidably connected to the front and rear of the top of the placing plate 4. When the rice bag contacts the buffer plate 13, the buffer plate 13 can buffer the rice bag. Four buffer springs 131 are connected between the lower part of the buffer plate 13 and the inner side of the placing plate 4.

[0041] When the rice bag is pouring rice, the operator can view the rice pouring situation through the observation window 12. In this way, it is possible to timely master the rice pouring situation and make corresponding treatments.

[0042] When the rice bag falls onto the placing plate 4, the rice bag contacts the buffer plate 13. Due to the action of the buffer spring 131, the buffer plate 13 buffers the rice bag, and the buffered rice bag falls onto the placing plate 4. In this way, it is possible to prevent the rice bag from falling violently onto the placing plate 4, resulting in loosening and deformation of the placing plate 4, thus ensuring the service life of the placing plate 4.

[0043] Finally, it is necessary to state that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention shall fall within the scope of protection required by the present invention.
