[0023] The following will further describe the present utility model in detail with reference to the embodiments given in the drawings.

[0024] Refer to Figure 1 As shown in Figure 3 FIG. 1, a corrugated cardboard box cutting device according to an embodiment of the present invention includes a machine body 1, an upper roller 2, a lower roller 3 and a waste recycling mechanism 4 disposed in the machine body 1. The waste recycling mechanism 4 is located below the lower roller 3. The rotation axes of the upper roller 2 and the lower roller 3 are parallel. A cutting knife is provided on the upper roller 2, and a cutting groove is provided on the lower roller 3. The position of the cutting groove coincides with the position of the cutting knife. A sponge rubber is provided in the cutting groove, and a baffle is provided on the sponge rubber. A separation mechanism 5 is provided in the machine body 1. The separation mechanism 5 includes:

[0025] An upper positioning roller 51, rotatably disposed on the frame, near the edge of the frame;

[0026] A lower positioning roller 52, rotatably disposed on the frame, below the upper positioning roller 51. A positioning gap is provided between the upper positioning roller 51 and the lower positioning roller 52;

[0027] A separation frame 53, fixedly disposed on the frame, in the area between the two upper positioning rollers 51. The upper roller 2, the upper positioning roller 51 and the separation frame 53 are arranged in sequence along the advancing direction of the cardboard.

[0028] Through the above technical solution, when the device operates, the upper roller 2 and the lower roller 3 continuously rotate. The cutting knife cooperates with the cutting groove to cut corresponding grooves in the passing cardboard in sequence. Then, with the reset of the sponge rubber, the paper scraps in the cutting groove are pushed out and fall into the waste recycling mechanism 4 below. The cardboard line leaving the upper roller 2 and the lower roller 3 passes through the positioning gap. Then it passes through the separation frame 53, making the cardboard passing through the separation frame 53 stable. The separation frame 53 can stably separate the paper scraps on the upper side of the cardboard.

[0029] The cut cardboard passes through the upper positioning roller 51 and the lower positioning roller 52, is positioned by them and then output to the subsequent separation mechanism 5. The separation mechanism 5 isolates the paper scraps that do not smoothly fall into the waste recycling mechanism 4, and only the cardboard continues to move forward, avoiding printing defects in the subsequent printing mechanism for the subsequent cardboard. Reducing the defective rate of cardboard printing for cartons.

[0030] As a specific improvement embodiment, the separation frame 53 includes:

[0031] Side plates 531, fixedly connected to the frame, at a position near the edge inside the frame;

[0032] Scrapers 532, fixedly disposed on the lower sides of the side plates 531. The lower sides of the scrapers 532 are in contact with the upper side surfaces of the cardboard;

[0033] The bottom plate 533 is connected to the scraping plate 532 and the side plates 531 to form a collection space that is open on one side and closed on the other side.

[0034] Through the above technical solution, as the cardboard is conveyed, the paper scraps on the upper side of the cardboard enter the upper side of the scraping plate 532 and stay in the collection space, where they can be cleaned regularly. The side plates 531 on both sides fix the scraping plate 532 and the bottom plate 533 on the machine frame, and the structure is stable.

[0035] Specifically, the scraping plate 532 is provided with an inclined guiding edge on the side facing the positioning roller 51, so that the paper scraps can enter the scraping plate 532 more easily.

[0036] As a specific embodiment of the improvement, the separation frame 53 includes:

[0037] The connecting plate 534 is fixedly arranged on the machine frame and is located at a position close to the edge of the machine frame. The connecting plate 534 is misaligned with the movement track of the cardboard.

[0038] The guiding plate 535 is fixedly connected to the connecting plate 534. The guiding plate 535 is vertically arranged, and the lower end surface abuts against the upper side surface of the cardboard.

[0039] Through the above technical solution, the guiding plate 535 is inclined. During the conveyance of the cardboard, the paper scraps in contact with the guiding plate 535 can be guided outward until they leave the upper side of the cardboard and fall into the waste recycling mechanism 4 below, eliminating the need for subsequent cleaning of the paper scraps and making it more convenient to use.

[0040] The connecting plate 534 connects the guiding plates 535 on both sides, with high structural strength and stable position.

[0041] As a specific embodiment of the improvement, the guiding plates 535 on both sides are connected and are conical in a top view.

[0042] Through the above technical solution, the guiding plates 535 on both sides are connected to form a cone, guiding the paper scraps to both sides, which can more quickly guide the paper scraps outside the cardboard and then fall into the waste recycling mechanism 4 below, reducing the residence time of the paper scraps on the cardboard and improving the stability during use.

[0043] As a specific embodiment of the improvement, a blanking roller 6 is provided on the machine frame. The blanking roller 6 is located below the lower roller 3. The blanking roller 6 is provided with bristles, and the bristles abut against the lower roller 3. The rotation direction of the blanking roller 6 is the same as that of the lower roller 3.

[0044] Through the above technical solution, the blanking roller 6 rotates synchronously with the lower roller 3. The paper scraps that fail to fall smoothly from the cutting slot (due to long-term use, the reset speed of the sponge rubber decreases and the reset force drops, resulting in the situation where the paper scraps cannot fall off normally) are brushed off by the brush when passing through the bristles, and then fall into the waste recycling mechanism 4 below, thereby improving the stability of the grooving process of the upper roller 2 and the lower roller 3.

[0045] Specifically, if there are no paper scraps in the cutting slot during the cutting process, the amount of paper scraps on the cardboard can be reduced. Cooperating with the separating mechanism 5, the defective rate of the cardboard printing of the carton can be further reduced.

[0046] As a specific implementation of the improvement, an auxiliary roller 7 is provided on the frame. The auxiliary roller 7 abuts against the blanking roller 6. The rotation direction of the auxiliary roller 7 is opposite to that of the blanking roller 6, and the linear speed of the auxiliary roller 7 is greater than that of the blanking roller 6.

[0047] Through the above technical solution, the auxiliary roller 7 rotates synchronously with the lower roller 3. When the paper scraps that fail to fall smoothly from the cutting slot pass through the auxiliary roller 7, the auxiliary roller 7 drives the paper scraps to move, so that the opening of the paper scraps is separated from the cutting slot, enabling the bristles to brush off the paper scraps more stably.

[0048] The above is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
