Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a debris cleaning device for a paper cutter. Background Art

[0002] Paper cutters are traditional products that are used to handle paper cutting needs in the later stages of printing. They are divided into two categories: fling knife paper cutters and flat knife paper cutters. During the use of paper cutters, a large amount of paper scraps and debris will be generated.

[0003] In the prior art, a lot of paper scraps and debris will remain on the cutting board of the paper cutter. When cleaning it, it is usually done after the paper material is processed and removed, and the surface of the cutting board is cleaned with the help of a broom-type device component. This cleaning method has shortcomings, such as manual cleaning is time-consuming, labor-intensive and inconvenient. Secondly, broom-type device components (broom hairs) easily accumulate dust in the air. Therefore, although it can remove paper scraps and debris on the cutting board, it is easy to leave dust, affecting the cleanliness of the surface of the cutting board, thereby affecting the cleanliness of the contact surface of the paper material subsequently placed thereon. Therefore, in order to address this problem, a debris cleaning device for a paper cutter is proposed herein. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1A debris cleaning device for a paper cutter includes a cutting board 1 and a paper body 2. The paper cutting equipment component is installed above the cutting board 1 and is not drawn in the figure. This scheme only draws the debris cleaning component and does not elaborate on the mature paper cutting equipment component in the prior art. For details, please refer to the prior art disclosure.

[0022] Reference Figure 2-4 A first rotating groove 3 is provided on the cutting paperboard 1, a first screw 4 is rotatably provided in the first rotating groove 3, a first motor 5 connected with the first screw 4 is provided on the outer wall of the cutting paperboard 1, and the first motor 5 can drive the first screw 4 to rotate.

[0023] A nut 6 is threadedly sleeved on the first screw rod 4, a movable plate 7 is provided on the nut 6 through a connecting mechanism, a lower pressing groove 16 is provided on the movable plate 7, a limit block 17 is provided in the lower pressing groove 16 through an elastic mechanism, a strip opening 14 corresponding to the limit block 17 and connected to the first rotating groove 3 is provided on the bottom wall of the cutting paper board 1, a second rotating groove 8 is provided on the movable plate 7, a second screw rod 9 is provided in the second rotating groove 8, a second motor 10 connected to the second screw 9 is provided on the outer wall of the movable plate 7, and the second motor 10 can drive the second screw 9 to rotate.

[0024] A movable frame 11 is threadedly sleeved on the second screw rod 9 , and a dust cover 12 is disposed on the movable frame 11 via a dust suction pipe 13 .

[0025] The connection mechanism includes an insert block 15 arranged on the nut 6, a slot corresponding to the insert block 15 is provided on the movable plate 7, a connection groove 20 corresponding to the nut 6 is provided on the movable plate 7, and the slot is arranged on the inner wall of the connection groove 20. The connection groove 20 has been drawn, and the structure of the insert block 15 is also drawn, and the position of the slot has also been described accordingly. The slot can be associated through the above description, so it is not drawn in the figure.

[0026] The elastic mechanism includes a spring 18 arranged in the downward pressure groove 16, and the two ends of the spring 18 are elastically connected to the outer wall of the limit block 17 and the inner wall of the downward pressure groove 16 respectively. The spring 18 is a conventional component, which realizes the downward pressure of the limit block 17. When the movable plate 7 is in the first rotating groove 3, the spring 18 can squeeze the limit block 17 into the strip-shaped opening 14 to prevent the movable plate 7 from being separated from the nut 6, thereby playing a limiting role.

[0027] The first rotation groove 3 is provided with a limit rod 19, which slides through the nut 6. The second rotation groove 8 is also provided with a limit rod 19, which slides through the moving frame 11. The limit rod 19 also plays a limiting role, effectively preventing the nut 6 from rotating with the first screw rod 4, and effectively preventing the moving frame 11 from rotating with the second screw rod 9.

[0028] When the utility model is used, Figure 1As shown, the paper body 2 is placed on the cutting board 1 and is processed by the paper cutting equipment components above the cutting board 1. After the processing, the remaining paper scraps are on the cutting board 1. At this time, the first motor 5 is started to drive the first screw 4 to rotate. When the first screw 4 rotates, the nut 6 will move, and the nut 6 will drive the moving plate 7 to move, thereby driving the dust cover 12 and other components to move. After moving them to a suitable position, the second motor 10 is started, and the second motor 10 drives the second screw 9 to rotate. When the second screw 9 rotates, the moving frame 11 will move, and finally drive the dust cover 12 and other components to move to just above the paper scraps that need to be cleaned, and then the power device such as the negative pressure pump connected to the dust suction pipe 13 is started, so that it relies on the dust suction pipe 13 and the dust suction hood 12 to realize the suction operation of the paper scraps, thereby realizing the cleaning operation of the surface of the cutting board 1.

[0029] In the present solution, when cleaning is not needed temporarily and the dust cover 12 and other components cause obstructions, a finger is inserted into the strip opening 14, and then the limit block 17 is pressed to compress the spring 18. Then the limit block 17 is separated from the strip opening 14 and enters the lower pressing groove 16. Then the limit release of the movable plate 7 is completed, and the movable plate 7 can be moved horizontally to separate it from the nut 6, etc.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
