[0032] A blowing assembly is installed on the housing 1 and the cover 8. The blowing assembly is used to blow impurities from one side to the other inside the cover 8.

[0033] The air intake assembly is installed on the housing 1 and the shell 3. The air intake assembly is used to collect the impurities blown out by the air blowing assembly.

[0034] In this embodiment, the paper 20 to be cut is placed on the top of the housing 3. The width of the housing 3 is the same as the width of the paper 20. During the cutting operation, the paper 20 is located in the opening slots 8-1 opened on both sides of the housing 8. The side walls of the housing 8 with the opening slots 8-1 can press onto the paper 20 to fix the paper 20.

[0035] As one embodiment of this utility model, the blower assembly includes:

[0036] A blower 11 is installed on the top of the cover 8, and an air inlet 1-1 is provided on the top of the box 1.

[0037] The air inlet pipe 12 is installed through one side of the top wall of the cover 8. One end of the air inlet pipe 12 is connected to the air outlet of the blower 11 and the other end is blocked. Multiple nozzles 13 are installed on the air inlet pipe 12.

[0038] A support plate 15 is provided on the side wall of the housing 3 and below the plurality of nozzles 13, and a sealing ring 16 is provided on the support plate 15.

[0039] In this embodiment, a fixing plate 14 is provided on the inner top wall of the cover 8, and multiple nozzles 13 are disposed through the fixing plate 14; when a pair of cylinders 4 drive the cover 8 to move vertically downward and press it onto the support plate 15, the sealing ring 16 between the support plate 15 and the cover 8 can prevent the compressed air blown out from the nozzles 13 from leaking out from the gap.

[0040] As one embodiment of this utility model, the air intake assembly includes:

[0041] The exhaust fan 18 is installed on the bottom wall inside the housing 1 and the air inlet 1-1 is connected to the housing 3.

[0042] Filter 19 is disposed inside the housing 3 on the side near the induced draft fan 18;

[0043] The flow guide 17 is connected to the side of the housing 3 away from the blower 18, and a sealing ring 16 is provided on the top of the flow guide 17.

[0044] In this embodiment, when a pair of cylinders 4 drive the cover 8 to move vertically downwards and press the cover 8 onto the guide shroud 17, the sealing ring 16 at the top of the guide shroud 17 can seal the gaps, so that a negative pressure is formed at the guide shroud 17 when the blower 18 is running.

[0045] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0046] The working principle and usage process of this utility model are as follows: When in use, open the box door 2, place the paper 20 to be cut on top of the housing 3, and align the paper 20 with the edge of the housing 3 (the width of the paper 20 and the housing 3 are the same); activate a pair of cylinders 4 located on the inner top wall of the box 1. The telescopic ends of the pair of cylinders 4 extend, causing the connected limiting block 6 to move vertically downwards. The limiting block 6 causes a pair of connected rods 5 to move vertically downwards. The connecting rods 5 cause the connecting plate 9 to move, and the connecting plate 9 causes the cover 8 to move. The cutting blade 10 moves downward. After the paper 20 is embedded in the opening slots 8-1 on both sides of the cover 8, a pair of cylinders 4 continue to drive a pair of limiting blocks 6 to move downward. When the limiting blocks 6 move downward, the spring 7 sleeved on the connecting rod 5 is compressed, which causes the side walls of the cover 8 with the opening slots 8-1 to press onto the paper 20 to fix the paper 20. The limiting blocks 6 continue to drive the connecting rod 5 to move vertically downward, which in turn drives the connecting plate 9 and the cutting blade 10 to move downward, so that the cutting blade 10 cuts the paper 20.

[0047] During the cutting process, the blower 11 set on the top of the cover 8 is started. The blower 11 delivers air into the air inlet pipe 12 and then sprays it out from multiple nozzles 13, so that the dust and debris generated during the cutting process are blown from one side of the cover 8 to the other side. The induced draft fan 18 is started, and the induced draft fan 18 creates a negative pressure inside the housing 3 and the guide hood 17, so that the dust and debris blown out first fall into the guide hood 17 and then enter the housing 3. The sealing ring 16 at the top of the support plate 15 and the guide hood 17 is used to seal the gaps between the support plate 15 and the cover 8, and between the guide hood 17 and the cover 8.

[0048] This invention fixes the paper 20 by pressing the two side walls of the cover onto the paper 20 during the cutting process. The cutting blade 10 cuts the paper 20, and the air supply component blows dust, debris and other impurities to one side inside the cover 8. The air intake component collects the dust and debris, which can effectively clean up the impurities generated during the cutting process, prevent damage to personnel health and reduce the operation and maintenance costs of the equipment.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
