[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides a creasing machine for paper packaging box production as Figures 1-4 shown, including:

[0022] A machine body 1, a creasing box 2 and a pressing mechanism 5. The creasing box 2 is arranged on the top of the machine body 1, the pressing mechanism 5 is arranged on the front of the creasing box 2, and an adjusting member for adjusting the height of the pressing mechanism 5 is arranged on one side of the top of the machine body 1;

[0023] The pressing mechanism 5 includes a pressing component and a lifting component. The pressing component includes a pressing plate 53. A compression spring 54 for pushing the pressing plate 53 is arranged at the top of the pressing plate 53. A connecting member for connecting with the lifting component is arranged at the top of the compression spring 54. A protection member for protecting the cardboard is arranged at the bottom of the pressing plate 53.

[0024] Specifically, a feeding plate 3 for cardboard feeding is arranged on the front of the creasing box 2, and a discharging plate 4 for receiving the creased paper box is arranged on the back of the creasing box 2.

[0025] Furthermore, the machine body 1, the creasing box 2, the feeding plate 3 and the discharging plate 4 form a digital creasing machine of the existing model NCC350. The outside of its creasing box 2 is a metal protective cover, and inside it are rollers for pulling the cardboard and creasing knives for making creases on the cardboard. Stack the cardboard on the top of the feeding plate 3. As the rollers inside the creasing box 2 rotate, the cardboard is driven into the inside of the creasing box 2. Under the extrusion of the creasing knives, the cardboard forms creases, and then the creased cardboard is conveyed to the discharging plate 4 to complete the creasing production of small paper packaging boxes.

[0026] Specifically, the lifting component includes a lifting plate 51. A linkage block 52 for driving the pressing component to move is fixedly connected to the bottom of the lifting plate 51. A second threaded hole is opened on one side of the top of the lifting plate 51. The adjusting member includes an adjusting rod 6. The adjusting rod 6 is threadedly inserted into the second threaded hole. A second round hole is opened on the other side of the top of the lifting plate 51. A limiting rod 7 is inserted into the second round hole. A round groove is opened on one side of the top of the machine body 1. A bearing 8 is sleeved on the outer wall of the bottom of the adjusting rod 6. The outer wall of the bearing 8 is fixedly connected to the inner wall of the round groove. The bottom end of the limiting rod 7 is fixedly connected to the other side of the top of the machine body 1.

[0027] Further, the thread on the inner wall of the second threaded hole meshes with the thread on the outer wall of the adjusting rod 6. The diameter of the second round hole is 1.01 times the diameter of the limiting rod 7. The bottom end of the limiting rod 7 is fixedly welded to the top end of the machine body 1. The height of the top end of the limiting rod 7 is flush with the height of the top end of the adjusting rod 6. The adjusting rod 6 is composed of a screw rod and a disc. Thus, under the limitation of the disc at the top of the adjusting rod 6, the lifting plate 51 cannot move out of the screw rod. The bearing 8 is fixedly sleeved on the outer wall of the bottom of the screw rod of the adjusting rod 6, and the outer wall of the bearing 8 is fixedly adhered to the inner wall of the round groove. Thus, by rotating the adjusting rod 6, the lifting plate 51 cannot rotate under the limitation of the limiting rod 7. Thus, the lifting plate 51 can only move up and down in the vertical direction. The bottom end of the lifting plate 51 is fixedly welded to the top end of the linkage block 52. Thus, the movement of the lifting plate 51 drives the movement of the linkage block 52. Adjusting the height of the linkage block 52 is to adjust the compression amount of the compression spring 54, so as to prevent the situation that the pressing plate 53 presses the cardboard tightly due to too large compression amount of the compression spring 54, resulting in the inability of the roller inside the creasing box 2 to pull the cardboard.

[0028] Specifically, a groove for installing a connecting member is provided at the bottom end of the linkage block 52. First threaded holes and first round holes are respectively provided at the bottom end of the front surface of the linkage block 52 and the front surface of the connecting member. A locking member for locking the connecting member and the linkage block 52 is inserted through the first threaded hole and the first round hole. The locking member includes a locking bolt 56. The locking bolt 56 is inserted through the first round hole, and the locking bolt 56 is threadedly inserted through the first threaded hole. The inner wall of the first round hole is a smooth inner wall. The connecting member includes a connecting plate 55. The top end and the bottom end of the compression spring 54 are respectively fixedly connected to the bottom end of the connecting plate 55 and the top end of the pressing plate 53. The protective member includes a protective pad 57. The protective pad 57 is sleeved on the outer wall of the bottom of the pressing plate 53.

[0029] Further, two connecting plates 55 are symmetrically arranged at the bottom end of the linkage block 52. The size of the connecting plate 55 fits the size of the groove. The thread on the inner wall of the first threaded hole of the locking bolt 56 meshes with the thread on the outer wall of the locking bolt 56. The first threaded hole is opened at the bottom of the linkage block 52, and the first round hole is opened on the front of the connecting plate 55. The diameter of the first round hole is 1.01 times the outer diameter of the locking bolt 56. The first threaded hole penetrates through the two grooves. Thus, by inserting the locking bolt 56 into the first threaded hole and the first round hole at the same time, the connecting plate 55 is fixedly connected to the bottom of the linkage block 52. The top and bottom ends of the compression spring 54 are fixedly connected to the bottom end of the connecting plate 55 and the top end of the pressing plate 53 by gluing respectively. The pressing plate 53 is made of a metal plate, and the protective pad 57 is made of sponge and sleeved on the outer wall of the bottom of the pressing plate 53. The part where the inner wall of the protective pad 57 is in contact with the outer wall of the pressing plate 53 is fixed by gluing. While ensuring that the pressing plate 53 presses the cardboard, the protective pad 57 protects the surface of the cardboard. The number of the pressing plates 53 corresponds to the number of the connecting plates 55. The design of the two pressing plates 53 can prevent the lower cardboard from moving when the upper cardboard is twitched because the next cardboard is pressed by the pressing plate 53 away from the creasing box 2. At the same time, when the cardboard is twitched, the surface of the cardboard will pass through the pressing of the pressing plate 53, so that the warped edge of the cardboard can be flattened.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
