Description

Technical Field

[0001] The present application relates to the technical field of carton production, and in particular to a creasing device for carton production. Background Art

[0002] Cartons are usually used as wrapping for goods or as outer protective layers for articles. Cartons are made by folding cardboard after slotting or creasing. The creasing of cartons is generally done using a creasing device to improve production efficiency.

[0003] Currently, when creasing a paperboard, the position of the creasing of the paperboard needs to be accurately positioned below the creasing knife, and the indentation position often deviates due to inaccurate positioning.

[0004] Therefore, it is necessary to design a creasing device for carton production that can be easily and accurately positioned at the creasing position. Utility Model Content

[0056] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0057] A creasing device for carton production, comprising: a bottom plate 1, a fixed plate 2, a movable plate 201, and a mounting plate 3;

[0058] Specifically, the bottom plate 1 is a rectangular plate structure, and four supporting legs 101 are fixedly installed near the four corners of the bottom surface of the bottom plate 1 to support the entire device; the fixed plate 2 is fixedly installed on the bottom plate 1, and the movable plate 201 is movably arranged on one side of the fixed plate 2 along the length direction of the bottom plate 1, and the fixed plate 2 and the movable plate 201 are connected by seven elastic members 202, and the elastic members 202 are springs;

[0059] Two guide plates 301 arranged opposite to each other are fixedly mounted on the bottom plate 1. The side wall of the guide plate 301 penetrates to form a guide groove 302 with an inverted T-shaped cross section. The extension direction of the guide groove 302 is the same as the length direction of the bottom plate 1. The cross section of the mounting plate 3 is inverted U-shaped. The mounting plate 3 is movably arranged in the guide groove 302. The outer wall of the mounting plate 3 located in the guide groove 302 is in contact with the inner wall of the guide groove 302. The mounting plate 3 is fixedly connected to the movable plate 201 through a connecting column 303.

[0060] Since the movable plate 201 is connected to the fixed plate 2 by a spring, the cardboard is pushed to a position where it contacts the movable plate 201. No matter how far the movable plate 201 moves, as long as the indentation piece is set at a fixed position on the mounting plate 3, the indentation piece can always accurately press at a corresponding position on the cardboard; that is, accurate indentation can be achieved as long as the cardboard contacts the movable plate 201, and there is no need to fix the cardboard at a precise position.

[0061] The creasing device for carton production also includes: a connecting shaft 4, a knife shaft 401, a creasing knife 402, and a driving assembly 5;

[0062] Specifically, two oppositely arranged indentation grooves 304 are formed through the top surface of the mounting plate 3, and the extending direction of the indentation groove 304 is the same as the width direction of the bottom plate 1; a connecting plate 305 is movably arranged in the indentation groove 304, and the bottom of the connecting plate 305 is fixedly connected to the two ends of the connecting shaft 4, and a driving plate 306 is arranged on the mounting plate 3, and the driving plate 306 is fixedly connected to the top surfaces of the two connecting plates 305;

[0063] More specifically, an external thread is formed on the connecting shaft 4, an internal thread matching the connecting shaft 4 is formed on the knife shaft 401, the knife shaft 401 is threadedly connected to the connecting shaft 4, and the indentation knife 402 is rotatably disposed on the knife shaft 401;

[0064] The relative position of the creasing knife 402 on the connecting shaft 4 can be adjusted by rotating the knife shaft 401, so that the creasing knife 402 is set at a fixed position away from the movable plate 201, and the distance between the creasing knife 402 and the movable plate 201 is the distance from the position on the cardboard to be creasing to the edge of the cardboard.

[0065] The driving assembly 5 includes a screw rod 501 and a slider 502. Specifically, two oppositely arranged bearing plates 503 are fixedly installed on the bottom plate 1. Both ends of the screw rod 501 are rotatably arranged on the bearing plates 503. A driving motor 504 is fixedly installed on one of the bearing plates 503. The output shaft of the driving motor 504 is fixedly connected to the screw rod 501. The slider 502 is threadedly engaged with the screw rod 501. When the screw rod 501 rotates, the slider 502 can reciprocate along the screw rod 501.

[0066] The two opposite side wall portions of the driving plate 306 are concave to form a movable slot 505. The extending direction of the movable slot 505 is the same as the length direction of the bottom plate 1. The bottom of the slider 502 is movably arranged on the movable slot 505.

[0067] When the cardboard squeezes the movable plate 201, the movable plate 201 drives the mounting plate 3 to move, thereby driving the driving plate 306 to move. After the driving plate 306 moves, the position of the slider 502 relative to the driving plate 306 changes. The slider 502 can always drive the driving plate 306 to move along the width direction of the bottom plate 1, thereby achieving indentation.

[0068] The creasing device for carton production further comprises a correction plate 6, on which a correction surface 601 and a driving surface 602 are formed; the front side wall of the bottom plate 1 is set as a reference surface L603, the correction surface 601 is set parallel to the reference surface L603, an angle α604 is formed between the driving surface 602 and the correction surface, and the value of α604 is 36°;

[0069] Specifically, the surface portion of the base plate 1 is concave to form two correction grooves 605 that are relatively arranged along the width direction of the base plate 1. The correction plate 6 is movably arranged in the correction groove 605. Two relatively arranged adjustment plates 606 are fixed on the base plate 1. The adjustment plates 606 are threadedly connected with adjustment screws 607. The adjustment screws 607 are rotatably connected to the correction plate 6. An adjustment knob 608 is fixed on one end of the adjustment screw 607 away from the correction plate 6. Rotating the adjustment knob 608 can change the position of the adjustment screw 607 relative to the adjustment plate 6. When the position of the adjustment knob 608 is changed, the correction plate 6 is driven to move, thereby changing the position of the correction plate 6.

[0070] The setting of the calibration plate facilitates pushing the cardboard to the middle position of the bottom plate 1, thereby avoiding the problem of incomplete indentation caused by deviation of the cardboard along the width direction of the bottom plate 1 when the cardboard is placed.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
