[0002] During the forming process of the packaging carton, the corners of the box produced by die-cutting have different degrees of tightness when the box is opened, and they need to be pre-folded before forming so that the box can be opened smoothly when packaging the product.

[0003] For example, in the prior art patent application with announcement number CN 220639073 U, two mirror-symmetrical L-shaped blocks are connected by sliding horizontally on the top surface of the base, and the end surface of each L-shaped block is rotatably connected to a bending plate. The top surface of each L-shaped block is vertically provided with a slot, and each slot is provided with a clamping member. The present utility model provides two L-shaped blocks on the top surface of the base, and rotatably connects a bending plate to each L-shaped block, so that the device can complete the pre-folding of two sides of the paper box at one time, reducing the number of operating steps when pre-folding the paper box, improving the pre-folding efficiency of the paper box, and also eliminating the need for workers to hold the paper box for pre-folding, which to a certain extent frees the operator's hands and reduces the worker's workload.

[0004] However, when the device pre-folds the packaging box, due to the lack of a limiting structure on both sides of the packaging box, after the packaging box is placed into the inner side of the card slot, it is necessary to repeatedly adjust the position of the packaging box so that the position where the packaging box needs to be bent is aligned with the bending part. This increases the operation steps and reduces work efficiency.

[0005] Therefore, it is necessary to provide a packaging box pre-folding device to solve the above technical problems. Utility Model Content

A packaging box pre-folding device comprises: a bottom plate 1;

[0028] A base 2 is fixedly mounted on the top of the bottom plate 1. A slide groove 21 is provided on the top of the base 2. A first drive motor 22 is fixedly mounted on one end of the base 2. A bidirectional threaded rod 23 is fixedly mounted on the output end of the first drive motor 22.

[0029] Two clamping seats 3, the bottoms of the two clamping seats 3 are respectively threadedly connected to the two ends of the outer side of the bidirectional threaded rod 23, the interiors of the two clamping seats 3 are provided with clamping grooves 31, the inner sides of the two clamping grooves 31 are provided with pressure plates 33, the tops of the sides of the two clamping seats 3 are fixedly installed with fixing plates 34, the tops of the fixing plates 34 are fixedly installed with a second drive motor 35, and the output end of the second drive motor 35 is fixedly installed with a bending plate 36;

[0030] Two sliding sleeves 4 are fixedly installed inside the bottom of the two clamping seats 3 respectively. The inner sides of the two sliding sleeves 4 are slidably connected with positioning members 41, and the top of the positioning member 41 is fixedly installed with a guide plate 43.

[0031] The first drive motor 22 drives the bidirectional threaded rod 23 to be threadedly connected inside the two clamping seats 3, so that the user can adjust the distance between the two clamping seats 3 conveniently;

[0032] The two positioning members 41 are both L-shaped plates, which can be adjusted by sliding on the inner side of the sliding sleeve 4 .

[0033] One end of the bidirectional threaded rod 23 is rotatably connected to one side of the inner side surface of the sliding groove 21 .

[0034] A hydraulic telescopic rod 32 is fixedly installed inside the side surfaces of the two clamping seats 3 , and one end of the two hydraulic telescopic rods 32 is fixedly installed on one side of the two pressing plates 33 .

[0035] The extension of the hydraulic telescopic rod 32 drives the pressing plate 33 to move, thereby clamping and limiting the packaging box.

[0036] A locking screw 42 is connected to the inner thread of the side surface of the sliding sleeve 4 , and one end of the locking screw 42 abuts against the side surface of the positioning member 41 .

[0037] The working principle of the packaging box pre-folding device provided by the utility model is as follows:

[0038] When in use, the user can first take out a packaging box that needs to be pre-folded and put it into the inner side of the clamping groove 31, and then adjust the two clamping seats 3 and the bending plate 36 so that the position where the packaging box needs to be bent is on the side of the bending plate 36, and then move the positioning member 41 to make the positioning member 41 slide on the inner side of the sliding sleeve 4, so that the side surfaces of the two positioning members 41 contact the two sides of the packaging box, and then rotate the locking screw 42 to limit the positioning member 41. In this way, when pre-folding packaging boxes of the same specification in the future, it is only necessary to move the packaging box from The top of the clamping groove 31 moves downward, causing the bottom of the packaging box to move downward along the guide plate 43, so that the two sides of the packaging box contact the sides of the two positioning members 41, thereby positioning the packaging box. The user does not need to repeatedly adjust the packaging box so that the pre-folded position of the packaging box is aligned with the position of the bending plate 36, thereby increasing work efficiency. The hydraulic telescopic rod 32 is then extended to drive the pressing plate 33 to clamp the packaging box, and then the second drive motor 35 is started to drive the bending plate 36 to rotate, so that the bending plate 36 pre-folds the packaging box.

[0039] Compared with the related art, the packaging box pre-folding device provided by the present invention has the following beneficial effects:

[0040] By installing the sliding sleeve 4 at the bottom of the two clamping seats 3, and then making the positioning piece 41 slide on the inner side of the sliding sleeve 4, and installing the guide plate 43 on the top of the positioning piece 41, when in use, the guide plate 43 can guide the packaging box that needs to be pre-folded to the middle of the two positioning pieces 41, so that the side surfaces of the two positioning pieces 41 are fitted against the side surfaces of the packaging box, which plays a role in positioning the packaging box. In this way, when pre-folding the packaging box, the user does not need to repeatedly adjust the position of the packaging box, thereby increasing work efficiency.

[0044] Springs 51 are fixedly mounted on both ends of one side of the clamping plate 52 .

[0045] One end of the two springs 51 is fixedly mounted on the inner side surface of the sliding cavity 51 .

[0046] The inner side surface of the sliding cavity 5 is provided with a limiting structure, which can limit the clamping plate 52 when in use, and prevent the clamping plate 52 from falling off from the inner side surface of the sliding cavity 5.

[0047] The working principle of the packaging box pre-folding device provided by the utility model is as follows:

[0048] When pre-folding the packaging box that needs to be pre-folded, the pressing plate 33 drives the clamping plate 52 to move toward the side of the packaging box, so that the side of the clamping plate 52 is in contact with the side of the packaging box and the spring 51 is contracted.
