[0016] Figure 1-Figure 7 The present invention shows an automatic box-turning system in one embodiment, which includes a positioning mechanism 1 and a flanging mechanism 2, and a bottom plate 3, a fixed plate 4 and an intermediate fixed plate 5 which are fixedly connected in sequence.

The positioning power device 11 is installed on the bottom plate 3, and the flanging power device 21 is installed at the bottom of the bottom plate 1. The inner slider 22, the outer slider 12 and the fixed plate 4 are fixedly connected to each other. Sliding connection, the flanging power device 21 passes through the bottom plate 3 and the fixed plate 4, and is connected to the inner slider 22, wherein a plurality of the outer sliders 12 are arranged around the periphery of a plurality of the inner sliders 22, and a gap is provided between the outer sliders 12 and the inner sliders 22 for the box body 7 to pass through, the outer slider 12 and the inner slider 22 can slide reciprocatingly relative to the fixed plate 4, the outer slider 12 and the inner slider 22 can be interlocked to clamp the flanging, and the intermediate fixed plate 5 is located above the inner slider 22, and cooperates with the outer slider 12 to clamp the box body.

[0017] The present invention provides an automatic box-turning system, which, by fitting the box 7 onto the intermediate fixed plate 5, makes the inner side of the edge of the box abut against the outer side of the inner slider 22, and then the positioning power device 11 drives the outer slider 12 to move inward, so that the plurality of outer sliders 12 abut against each other and cooperate with the intermediate fixed plate 5, thereby clamping the box 7, and then, by using the flanging power device 21 to drive the plurality of inner sliders 22 to move outward, so that the plurality of inner sliders 22 push the edge of the box 7 toward the inner side of the outer slider 12 from the inner side of the box 7 and fold it, and at the same time, the inner slider 22 gradually engages with the outer slider 12 during the process of moving outward, thereby clamping and stabilizing the flanging of the box 7, and keeping the flanging of the box flat, thereby not only achieving the bending of the edge of the box 7 into an L-shaped flanging, but also ensuring that the L-shaped flanging is uniform and flat, meeting the process quality requirements, and thereby improving the production efficiency.

[0018] Furthermore, in this embodiment, if Figure 5 and Figure 7As shown, an inverted step-like structure 121 is formed on the inner side of the outer slider 12, and a positive step-like structure 221 is formed on the outer side of the inner slider 22. The inverted step-like structure 121 and the positive step-like structure 221 are interlocked with each other. A positioning block 222 is also installed on the positive step-like structure 221. The positioning block 222 is slightly higher than the positive step-like structure 221. When the box body 7 is mounted on the intermediate fixing plate 5, the positioning block 222 is used to press against the box body to stop the box body 7 from moving downward. At this time, the height difference between the intermediate fixing plate 5 and the top surface of the positioning block 222 is the width of the edge of the box body 7 that needs to be folded, and the positioning block 222 is detachably connected to the positive step-like structure 221.

[0019] Furthermore, in this embodiment, if Figure 3-Figure 5 As shown, the flanging power device 21 includes a lower oil cylinder 211 installed at the bottom of the base plate, and a conical push rod 212 connected to the lower oil cylinder 211 and capable of reciprocating up and down. The flanging mechanism 2 includes at least two flanging power devices 21 and two inner slides 22. A pulley groove 223 is provided on the inner side of the inner slide 22. The pulley groove 223 is connected to a longitudinally arranged pulley 224. The pulley 224 cooperates with the conical surface of the conical push rod 212. When the lower oil cylinder 211 drives the conical push rod 2 When the box body 12 rises, the conical push rod 212 pushes the inner slide 22 toward the outer slide 12 through the cooperation between its conical surface and the pulley 224, and the inner slide 22 folds and bends the edge of the box body 7 toward the inverted step-shaped structure 121 of the outer slide 22 from the inner side of the box body 7. During the outward movement of the inner slide 22, it gradually interlocks with the outer slide 12, and through the interlocking with the outer slide 12, the folded edge of the box body 7 is clamped and pressed, so that the flange of the box body remains flat. The fixing plate 4 is provided with an inner limit block 41, the inner slider 22 is provided with an inner limit groove 225 slidably connected to the inner limit block 41, the inner limit block 31 is also connected with a return spring, the return spring is connected with the inner limit groove 225, the inner slider 22 is also provided with an inner linkage groove 226, the inner linkage grooves 226 of two adjacent inner sliders 22 are movably connected with an inner linkage block 227, the inner limit block 31 is also provided with a connecting hole, the connecting column of the intermediate fixing plate 5 passes through the connecting hole and is connected to the fixing plate 4; In this embodiment, specifically, Figure 4 and Figure 5As shown, the flanging power mechanism 2 includes four flanging power devices 21 and four inner sliders 22, the inner limit groove 225 is arranged on the diagonal line of the inner slider 22, the inner linkage block 227 is arrow-shaped, and the flanging power device 21 drives the inner slider 22 to reciprocate along the length direction of the inner limit block 41. When the inner slider 22 moves outward, the inner linkage block 227 constrains two adjacent inner sliders 22, so that the two adjacent inner sliders 22 move synchronously. At the same time, the reaction force exerted by the two adjacent inner sliders 22 on the inner linkage block 227 pushes the inner linkage block 227 to move together, thereby maintaining an active connection state between the inner linkage block 227 and the inner linkage groove 226.

[0020] When the inner slider 22 moves outward, it also moves outward relative to the inner limit block 41, thereby squeezing the return spring. When the flanging operation is completed, the flanging power device 21 drives in the reverse direction to reset the conical push rod 212. At this time, the squeezed return spring restores its original shape through the elastic force and pushes the inner slider 22 to move inward relative to the inner limit block 41, thereby resetting the inner slider 22.

[0021] Furthermore, the positioning mechanism 1 includes at least two positioning actuators 11 and two outer slides 12. In this embodiment, Figure 6 As shown, the positioning mechanism 1 includes 4 positioning power devices 11 and 4 outer slides 12, an outer limit block 42 is installed on the fixed plate 4, the outer slide 12 is provided with an outer limit groove 122 slidably connected to the outer limit block 42, the outer limit block 42 is also connected to the outer limit groove 122 through a return spring, the outer slide 12 is also provided with an outer linkage groove 123, the outer linkage grooves 123 of two adjacent outer slides 12 are jointly movably connected with an outer linkage block 124, the positioning power device 11 is oiled Cylinder, the output shaft of the upper oil cylinder is movably connected with a rotating joint 111, and the rotating joint 111 is movably connected to the outer sliding block 12. When the size of the box to be flanging is large, the rotating joint 111 can be rotated and folded relative to the output shaft of the upper oil cylinder and the outer sliding block 12, so as to be flexibly adjusted to make the outer sliding block 12 adapt to boxes of different sizes. In this embodiment, the outer limiting groove 122 is arranged on the diagonal of the outer sliding block 12. Under the action of external force, the outer sliding block 12 reciprocates along the length direction of the outer limiting block 42, and the two adjacent outer sliding blocks 12 are constrained by the outer linking block 124 and move simultaneously, and the reaction force exerted by the two adjacent outer sliding blocks 12 on the outer linking block 124 drives the outer linking block 124 to move outward accordingly, thereby, the two adjacent outer sliding blocks 12 and the outer linking block 124 maintain a movably connected relationship and constrain each other.

[0022] Furthermore, in this embodiment, the bottom plate 3 , the fixing plate 4 , and the middle fixing plate 5 are all provided with through holes for the conical push rod 212 to pass through.

[0023] Furthermore, in this embodiment, if Figure 6 As shown, a wear-resistant block 31 is also installed on the base plate 3. The wear-resistant block 31 is made of high-hardness alloy steel. The wear-resistant block 31 passes through the fixed plate 4 and presses against the outer slider 12 and the inner slider 22. The surface of the wear-resistant block 31 is smooth, which reduces the friction between the fixed plate 4 and the outer slider 12 and the inner slider 22, and reduces the degree of wear of the fixed block 4, the outer slider 12 and the inner slider 22.

[0024] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the base plate 3 is also equipped with a clamp 32 and an outer stopper 33.

The clamp 32 is connected to the control main box. The outer baffle 33 is used to provide positioning assistance. When it is necessary to replace some components of the flipping system to adapt to different sizes of boxes, the positioning of the outer baffle 33 can assist in updating the flipping system. The clamp 32 is electrically connected to the control electrical box. The control main box controls the movement of the clamp 32 according to the preset program requirements. When the flipping system of different boxes needs to be replaced, the control main box controls the movement of the clamp to facilitate the replacement of the flipping system.

[0025] Furthermore, in this embodiment, if Figure 1 , Figure 2 as well as Figure 3 and Figure 6 As shown, a pressure plate 6 is also provided above the outer sliding block 12, and the outer limit block 42 is provided with a mounting hole.
