Description

Technical Field

[0001] The utility model belongs to the technical field of carton production and processing devices, and particularly relates to a precise cutting device for carton processing. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons and single-layer cardboard boxes, etc., with various specifications and models. As an indispensable part of modern logistics, cartons undertake the important responsibilities of packaging, protecting products, and being aesthetically pleasing. Therefore, cartons are widely used in people's production and life. During the production and processing of cartons, it is necessary to cut cardboard.

[0003] Problems existing in the prior art:

[0004] When cutting cardboard, the cardboard is generally stacked and cut simultaneously to improve work efficiency. Before cutting, it needs to be clamped and fixed. When precise cutting is required, it is even more necessary to firmly limit the clamped cardboard. If the clamping is not firm, it is very difficult to cut out cardboard with uniform specifications for processing cartons. Although most of the existing cardboard cutting devices have limiting devices, they lack the function of sorting a stack of cardboard, resulting in the inability of a stack of cardboard to completely overlap and being uneven with each other. In this way, it is necessary to reserve more dimensions when producing cardboard to prevent defective products. These extra reserved cardboard pieces become waste materials after cutting, which is very wasteful. Content of the Utility Model

[0005] The purpose of the utility model is to provide a precise cutting device for carton processing. Through the design of a reciprocating component, the sorting push plate can reciprocate at a high speed, sort the cardboard before the clamping push plate one and the clamping push plate two clamp and fix the cardboard, making the stacked cardboard better overlap. At the same time, the high-frequency soft contact sorting is not easy to squeeze and deform the cardboard. The device can also press the cardboard through the pressing slider after sorting the cardboard, making the cardboard more compact, improving the cutting quality during cutting. Through the design of the pressing slider, the pressing intensity of the pressing slider can be automatically controlled to prevent the cardboard from being deformed due to excessive pressing force.

[0028] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific requests of the present utility model.

[0029] As Figure 1 - Figure 4 shown, a precise cutting device for carton processing includes: a bottom plate 1, a cutting assembly 3, a clamping push plate 1 2, and two clamping push plates 2 4 are respectively arranged at four sides of the top of the bottom plate 1. The two clamping push plates 2 4 are symmetrically arranged. The cutting assembly 3 is arranged opposite to the clamping push plate 1 2. A baffle is fixedly connected to the bottom plate 1 at a position close to the middle corresponding to the cutting assembly 3.

[0030] Referring to the attached Figure 1 - Figure 4 , a propulsion structure 5 is arranged on one side of the clamping push plate 2 4 and the clamping push plate 1 2 away from the center position of the bottom plate 1. The clamping push plate 2 4 includes a clamping fixing plate 6. A sorting push plate 10 is arranged on one side of the clamping fixing plate 6. An activity cavity is opened at the position of the clamping fixing plate 6 where the sorting push plate 10 is located. The side of the sorting push plate 10 close to the clamping fixing plate 6 is located inside the activity cavity. A reciprocating assembly is arranged between the sorting push plate 10 and the activity cavity. The sorting push plate 10 is slidably connected to the activity cavity; referring to the attached Figure 1 - Figure 4 , two vertical pressing screws 7 are arranged on both sides inside the clamping fixing plate 6. A sliding cavity is opened at the position of the clamping fixing plate 6 corresponding to the pressing screws 7. The pressing screws 7 are located inside the sliding cavity and are rotatably connected to the sliding cavity. A pressing slider 8 is arranged on the outer surface of the pressing screws 7. The structure of the clamping push plate 1 2 is similar to that of the clamping push plate 2 4. A driving assembly is arranged on one side of the clamping push plate 2 4 away from the center position of the bottom plate 1. The driving assembly is used for the lateral movement of the clamping push plate 2 4.

[0031] According to the above structure, when cutting cardboard, the stacked cardboard is placed in the middle position of the bottom plate 1, and then the position of the clamping push plate 2 4 is adjusted. After adjusting to a suitable position, the propulsion structure 5 is started. When the propulsion structure 5 is started, the reciprocating assembly is also started. At this time, the sorting push plate 10 reciprocates at a high frequency inside the clamping push plate 1 2 and the clamping push plate 2 4. Under the action of the propulsion structure 5, the clamping push plate 1 2 and the clamping push plate 2 4 clamp the cardboard. The sorting push plate 10 sorts the stacked cardboard. Under the impact of high-frequency soft contact, each cardboard will be evenly stacked together. Then, the motor inside the clamping push plate 1 2 and the clamping push plate 2 4 drives the pressing screws 7 to rotate. At this time, the pressing slider 8 moves under the threaded connection of the pressing screws 7, so that the pressing slider 8 presses the cardboard tightly.

[0032] Referring to the attachedFigure 5 - Figure 6 The reciprocating assembly includes a driving motor 13 which is fixedly installed inside the clamping fixing plate 6. The output end of the driving motor 13 is fixedly connected with a rotating connecting rod 12. Vertically arrayed and fixedly connected to the outer wall of the edge of the rotating connecting rod 12 are semi-circular gear discs 14. Corresponding to the height position of the semi-circular gear discs 14, a reciprocating gear ring 11 is fixedly connected to the sorting push plate 10. The reciprocating gear ring 11 is meshed with the semi-circular gear discs 14.

[0033] According to the above structure, after the driving motor 13 is started, through the meshing connection between the semi-circular gear discs 14 and the reciprocating gear ring 11, when one side of the teeth of the semi-circular gear discs 14 is meshed with the reciprocating gear ring 11, the reciprocating gear ring 11 drives the sorting push plate 10 to move in one direction. When the other side of the teeth of the semi-circular gear discs 14 is meshed with the reciprocating gear ring 11, the reciprocating gear ring 11 drives the sorting push plate 10 to move in the opposite direction, so that the sorting push plate 10 can reciprocate inside the clamping push plate one 2 and the clamping push plate two 4 at a high frequency.

[0034] Refer to the appendix Figure 7 , the pressing slider 8 includes a threaded pressing block 15. At the bottom of the threaded pressing block 15 is provided a sliding key cap 17. A groove is formed in the pressing slider 8 corresponding to the position of the sliding key cap 17. The sliding key cap 17 is slidably assembled inside the groove. A pressing spring 20 is fixedly connected between the sliding key cap 17 and the groove. A threaded hole 16 is formed in the threaded pressing block 15 corresponding to the position of the pressing screw rod 7. The pressing screw rod 7 is threadedly connected with the threaded hole 16; fixedly connected inside the threaded pressing block 15 corresponding to the groove is an upper electrode contact block 18, and fixedly connected inside the groove corresponding to the sliding key cap 17 is a lower electrode contact block 19. Both the upper electrode contact block 18 and the lower electrode contact block 19 are electrically connected; a pressure sensing block 9 is further provided on the side wall of the clamping fixing plate 6. The structure of the pressure sensing block 9 is similar to that of the pressing slider 8, and the pressure sensing block 9 is fixedly connected with the clamping fixing plate 6.

[0035] According to the above structure, during the process of the pressing slider 8 pressing down on the cardboard, the sliding key cap 17 contacts the cardboard. As the pressing slider 8 presses down, the pressing spring 20 is compressed, and the sliding key cap 17 moves towards the inside of the groove. When the lower electrode contact block 19 contacts the upper electrode contact block 18, the electrical connection between the upper electrode contact block 18 and the lower electrode contact block 19 forms a circuit, transmitting an electrical signal. At this time, the pressing screw rod 7 stops rotating, and the pressing slider 8 stops moving to press the cardboard. The structure of the pressure sensing block 9 is similar to that of the pressing slider 8 and will not be elaborated further.

[0036] The working principle of the present utility model is as follows: When it is necessary to cut cardboard, the stacked cardboard is placed in the middle position of the bottom plate 1, and then the position of the clamping push plate two 4 is adjusted. After adjusting to a suitable position, the propulsion structure 5 is started. When the propulsion structure 5 is started, the driving motor 13 is started at the same time. After the driving motor 13 is started, it is meshed and connected with the reciprocating tooth ring 11 through the semi-circular tooth disc 14. When the semi-circular tooth disc 14 meshes with the tooth teeth on one side of the reciprocating tooth ring 11, the reciprocating tooth ring 11 drives the sorting push plate 10 to move in one direction. When the semi-circular tooth disc 14 meshes with the tooth teeth on the other side of the reciprocating tooth ring 11, the reciprocating tooth ring 11 drives the sorting push plate 10 to move in the opposite direction, so that the sorting push plate 10 can reciprocate inside the clamping push plate one 2 and the clamping push plate two 4 at a high frequency. At this time, the sorting push plate 10 reciprocates inside the clamping push plate one 2 and the clamping push plate two 4 at a high frequency. Under the action of the propulsion structure 5, the clamping push plate one 2 and the clamping push plate two 4 clamp the cardboard, and the sorting push plate 10 sorts the stacked cardboard. Under the impact of high-frequency soft contact, each cardboard will be evenly stacked together. Then, the motor inside the clamping push plate one 2 and the clamping push plate two 4 drives the pressing screw 7 to rotate. At this time, the pressing slider 8 moves under the threaded connection of the pressing screw 7. During the process of the pressing slider 8 pressing down on the cardboard, the sliding key cap 17 contacts the cardboard. As the pressing slider 8 presses down, the pressing spring 20 is compressed, and the sliding key cap 17 moves towards the groove. When the electrode contact lower block 19 contacts the electrode contact upper block 18, the electrical connection between the electrode contact upper block 18 and the electrode contact lower block 19 forms a circuit, transmitting an electrical signal. At this time, the pressing screw 7 stops rotating, and the pressing slider 8 stops moving to press the cardboard; at the same time, the pressure sensing blocks 9 on the clamping push plate two 4 and the clamping push plate one 2 generate pressure due to contact with the cardboard, causing the same structure inside the pressure sensing block 9 and the pressing slider 8 to generate an electrical signal, stopping the operation of the propulsion structure 5, and making the clamping push plate two 4 and the clamping push plate one 2 stop moving, simultaneously realizing the clamping and fixing of the cardboard.

[0037] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
