[0002] The multi-layer synchronous cutting paper cutter adopts an electric or hydraulic drive system, and the paper is cut by the up and down movement of the cutter. The multi-layer synchronous cutting paper cutter is widely used in the paper processing industry, such as printing plants, packaging plants, paper processing plants, etc. It can be used to cut paper, cardboard, cardboard and other materials to make books, magazines, packaging boxes, greeting cards and other products. The multi-layer synchronous cutting paper cutter is a high-efficiency and high-precision paper processing equipment, and its appearance has greatly improved the efficiency and quality of paper processing.

[0003] When the existing paper cutters are in use, their operating spaces are mostly exposed to the outside. When in use, most of them are equipped with protective doors to protect them and avoid injuries when cutting paper. However, when cutting paper, paper scraps and powder will adhere to the surface of the protective door. Usually, the protective door is covered with a transparent acrylic plate to facilitate personnel to observe the paper cutting work. The adhesion of paper scraps and powder will affect the normal observation of personnel and needs to be cleaned regularly, affecting the processing efficiency. Utility Model Content

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a multi-layer synchronous cutting paper cutter, including a base 1, an operating table 2 is fixed on the top of the base 1, a cylinder 3 is fixed on the top of the operating table 2, the output end of the cylinder 3 passes through the operating table 2, and a connecting plate 4 is fixed at the bottom of the output end of the cylinder 3, the connecting plate 4 passes through the operating table 2, and the connecting plate 4 is slidably connected to the operating table 2, and a protective component 6 and a cleaning component 7 are arranged on the surfaces of the base 1 and the operating table 2, the protective component 6 includes: a rack 1 60, a gear 1 61, a rack 2 62, and a protective plate 63, and the cleaning component 7 includes: a slide plate 70, an L-shaped rod 71, a resistance block 72, an L-shaped plate 73, a through hole 74, a clamping plate 75, a spring 1 76, a U-shaped plate 77, and a spring 2 78.

[0022] The slide plate 70 is slidably connected to the top of the inner wall of the base 1, an L-shaped rod 71 is fixed to the surface of the protective plate 63, a resistance block 72 is fixed to the bottom of the slide plate 70, an L-shaped plate 73 is fixed to the side of the slide plate 70 away from the protective plate 63, a through hole 74 is opened on the surface of the base 1, a clamping plate 75 is slidably connected to the inner wall of the through hole 74, a spring 1 76 is fixed to the top of the clamping plate 75, the top of the spring 1 76 is fixed to the top of the inner wall of the through hole 74, a U-shaped plate 77 is fixed to the bottom of the rack 1 60, a spring 2 78 is fixed to the side of the slide plate 70 away from the protective plate 63, and the end of the spring 2 78 away from the slide plate 70 is fixed to the surface of the base 1, the protective plate 63 moves up, and the brush The surface of the protective plate 63 is cleaned. When the protective plate 63 rises, it will synchronously drive the L-shaped rod 71 to rise synchronously. The top of the L-shaped rod 71 abuts against the inclined surface of the abutment block 72, and the slide plate 70 drives the brush to move away from the protective plate 63. When the side of the clamping plate 75 away from the inclined surface abuts against the surface of the L-shaped plate 73, the clamping plate 75 limits the L-shaped plate 73 and the slide plate 70. When the cutting is completed, the cylinder 3 is turned on to reset, the rack 60 rises, the U-shaped plate 77 rises, the top of the U-shaped plate 77 abuts against the bottom of the clamping plate 75, the clamping plate 75 rises, the limit on the L-shaped plate 73 is released, the spring 2 78 is released, and the slide plate 70 drives the brush to reset. At this time, the brush fits the surface of the protective plate 63 again.

[0023] A rack 60 is fixed on the surface of the connecting plate 4, and the rack 60 is slidably connected to the surfaces of the base 1 and the operating table 2. The surface of the operating table 2 is rotatably connected to a gear 61, and the rack 60 meshes with the gear 61. A protective plate 63 is slidably connected to the surface of the base 1, and a rack 2 62 is fixed on the surface of the protective plate 63, and the rack 2 62 meshes with the gear 1 61. The cylinder 3 is turned on, and the connecting plate 4 drives the paper cutter 5 to move downward to cut the paper. At the same time, when the connecting plate 4 moves downward, the rack 60 is synchronously driven downward. At this time, the gear 61 rotates, driving the rack 2 62 and the protective plate 63 to move upward, so as to shield the operating table 2. The material of the protective plate 63 is a transparent acrylic plate, which is convenient for personnel to observe the cutting work.

[0024] A paper cutter 5 is fixed to the bottom of the connecting plate 4 to facilitate cutting of paper. A brush is fixed to the side of the slide plate 70 close to the protective plate 63 to facilitate cleaning. The side of the abutment block 72 close to the protective plate 63 is set to be in the shape of an inclined plane. When abutted, the slide plate 70 can be driven to move. A collection box 8 is placed under the base 1 to facilitate collecting swept waste chips and powder. The side of the card plate 75 close to the L-shaped plate 73 is set to be in the shape of an inclined plane. When abutted, the card plate 75 can move.

[0025] When paper cutting is required, multiple layers of paper are placed in the operating table 2, the cylinder 3 is turned on, and the connecting plate 4 drives the paper cutter 5 to move down to cut the paper. At the same time, when the connecting plate 4 moves down, the rack 60 is synchronously driven to move down. At this time, the gear 61 rotates, driving the rack 2 62 and the protective plate 63 to move up, so as to shield the operating table 2. The material of the protective plate 63 is a transparent acrylic plate, which is convenient for personnel to observe the cutting work. At the same time, when the protective plate 63 moves up, the brush can clean the surface of the protective plate 63. When the protective plate 63 rises, it will synchronously drive the L-shaped rod 71 to rise synchronously. When the protective plate 63 is at the top, the top of the L-shaped rod 71 contacts the inclined surface of the contact block 72. At this time, the slide plate 70 drives the brush to move away from the protective plate 63, and the spring 2 78 is compressed, synchronously driving the L-shaped plate 73 to move. At this time, the surface of the L-shaped plate 73 contacts the inclined surface of the card plate 75. The card plate 75 moves up, and the spring 1 76 is compressed. When the card plate 7 When the side away from the inclined surface is located on the left side of the L-shaped plate 73, the spring 1 76 is released, the card plate 75 is reset, and the side of the card plate 75 away from the inclined surface contacts the surface of the L-shaped plate 73, and the card plate 75 limits the L-shaped plate 73 and the slide plate 70. When the cutting is completed, the cylinder 3 is turned on to reset, the rack 1 60 rises, and the U-shaped plate 77 is synchronously driven to rise. The top of the U-shaped plate 77 contacts the bottom of the card plate 75, thereby causing the card plate 75 to rise. At this time, the card plate 75 is separated from the L-shaped plate 73, and the limit on the L-shaped plate 73 is released. The spring 2 78 is released, and the slide plate 70 drives the brush to reset. At this time, the brush is again in contact with the surface of the protective plate 63, so that the protective plate 63 is raised and the brush is cleaned. When the protective plate 63 is lowered, the brush does not clean, which can prevent the brush from driving the waste chips and powder to move, affecting the cleaning effect. The cleaned waste chips and powder fall into the collection box 8, and the personnel can draw out the collection box 8 for cleaning when performing the cutting work.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
