Description

Technical Field

[0001] The utility model belongs to the field of packaging box processing, in particular to a folding device for producing packaging gift boxes. Background Art

[0002] The main purpose of folding the packaging box is to enhance the structural strength, make the packaging box more sturdy, be able to withstand a certain amount of pressure and weight, and reduce the risk of damage during transportation and storage; at the same time, the folding process can make the packaging box more regular and beautiful, and enhance the overall image of the product. The main folded part is the reserved opening of the packaging box.

[0003] When processing the packaging box, the main paperboard (grey board) needs to be pasted on the pre-printed color surface, and the excess color surface on the side (i.e. the folded edge) needs to be folded inward and pasted; currently, the folding process is mainly done manually, and the use of mechanized equipment for folding is mainly to fold and flip the folded edge and paste it on the color surface. However, in the actual processing process, there is a certain frequency that the folded edge cannot be firmly pasted on the main paperboard, and the folded edge will warp. The main reason is that the pressing force between the main paperboard and the folded edge is not enough, resulting in poor pasting effect. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figures 1 to 6 As shown, the embodiment of the utility model provides a folding device for producing packaging gift boxes, which is used to fold the folding portion 71 of the gift box paperboard 7, including: a processing table 1, on which two positioning plates 11 are provided and used to position the gift box paperboard 7, and the processing table 1 is also provided with a pressing component 12 for pressing the gift box paperboard 7, and the angle between the two positioning plates 11 has a certain angle, which is used to adapt to different gift box paperboards 7;

[0026] The end of the gift box paperboard 7 processed here is a rectangular plate, so the angle between the two positioning plates 11 is 90 degrees; the gift box paperboard 7 is positioned between the two positioning plates 11, the end of the gift box paperboard 7 is flush with the side of the processing table 1, and the folded edge 71 of the gift box paperboard 7 is located outside the processing table 1;

[0027] A mounting block 2, the mounting block 2 is located beside the processing table 1, and the mounting block 2 can be raised and lowered and moved laterally toward or away from the processing table 1 by power drive; a pressure roller 3, the pressure roller 3 is elastically connected to the mounting block 2 through two groups of elastic telescopic parts 4, the pressure roller 3 is located obliquely below the mounting block 2 and close to the processing table 1, and the pressure roller 3 is rotatably arranged at the ends of the two groups of elastic telescopic parts 4.

[0028] In this embodiment, the gift box paperboard 7 to be processed can be placed between the two positioning plates 11 to achieve preliminary positioning, and then the gift box paperboard 7 can be pressed by the pressing component 12, so as to ensure the position of the paperboard and prevent the paperboard from shifting during the folding process;

[0029] During actual processing, first, the pressing roller 3 is moved laterally to be close to the side of the processing table 1, and the pressing roller 3 is placed directly below the folded edge portion 71 of the gift box paperboard 7. Subsequently, the pressing roller 3 moves upward, thereby pushing the folded edge portion 71 of the gift box paperboard 7 to flip upward. When the pressing roller 3 moves to the upper surface of the processing table 1, the pressing roller 3 moves laterally and pushes the folded edge portion 71 to continue to flip. Since the gift box paperboard 7 has a certain thickness, when the pressing roller 3 pushes the folded edge portion 71 to flip and roll on the gift box paperboard 7, the elastic telescopic member 4 will have a certain amount of contraction, thereby increasing the elastic pressure of the pressing roller 3 on the folded edge portion 71 and the gift box paperboard 7. Under the elastic squeezing action of the pressing roller 3, the pressing roller 3 rolls along the gift box paperboard 7, so that the pressing roller 3 completely folds the folded edge portion 71 and firmly adheres it to the gift box paperboard 7, thereby realizing the folding processing of the gift box paperboard 7.

[0030] According to the actual processing situation, the staff observes the folding firmness effect of the gift box paperboard 7. If the folding firmness of the gift box paperboard 7 is still not enough, after the pressure roller 3 rolls the folding portion 71 and needs to be reset, the mounting block 2 moves downward again by a certain distance (1-3CM), thereby allowing the pressure roller 3 to give a strong elastic pressure to the folding portion 71 under the action of the elastic telescopic member 4. As the pressure roller 3 retreats and resets, the pressure roller 3 rolls over the folding portion 71 again, thereby allowing the folding portion 71 to be firmly adhered to the gift box paperboard 7, thereby improving the folding effect of the gift box paperboard 7.

[0031] Specifically, each group of elastic telescopic parts 4 includes a cylinder 41, a spring 42, a round rod 43 and a connecting rod 44 located at one end of the round rod 43; the cylinder 41 is fixedly mounted on the mounting block 2, the round rod 43 is slidably arranged in the cylinder 41, the spring 42 is located in the cylinder 41 and elastically resists the round rod 43; the two ends of the pressure roller 3 are respectively rotatably arranged in the rotating holes 441 on the two connecting rods 44; the end of the cylinder 41 close to the corresponding connecting rod 44 is provided with a rectangular rod 411 extending along the radial direction of the cylinder 41, the round rod 43 is provided with a rectangular groove 431 that penetrates its body along its radial direction, and the rectangular rod 411 is slidably arranged in the rectangular groove 431, which not only avoids relative rotation between the round rod 43 and the cylinder 41, but also limits the moving stroke of the round rod 43 to prevent the round rod 43 from falling off from the cylinder 41; when the round rod 43 slides along the axial direction of the cylinder 41, the rectangular rod 411 slides in the rectangular groove 431.

[0033] The lifting drive mechanism 6 includes a frame 61, a screw rod 62, a rotation drive source 63 and two guide rods 64; the frame 61 is installed at the sliding end of the electric linear slide 51, and the two guide rods 64 are longitudinally installed on the inner side of the frame 61, and the two guide rods 64 pass through the mounting block 2 and are slidably connected to the mounting block 2. One end of the screw rod 62 is rotatably connected to the frame 61, and the screw rod 62 longitudinally passes through the mounting block 2 and is threadedly connected to the mounting block 2. The rotation drive source 63 is installed on the frame 61 and its output end is transmission-connected to the other end of the screw rod 62; the rotation drive source 63 drives the screw rod 62 to rotate, and then drives the mounting block 2 to rise and fall along the two guide rods 64, thereby realizing the longitudinal drive of the pressure roller 3, and cooperating with the electric linear slide 51 to realize the lateral drive of the pressure roller 3.
