Implementation

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 , 2As shown, a conveying pressure wheel of a paper cutter comprises a fixed frame 1, an adjusting component 2 and a pressure wheel 3, wherein the adjusting component 2 is arranged on the top of the fixed frame 1, the pressure wheel 3 is arranged on the bottom of the adjusting component 2, and the control component 6 is arranged on the surface of the fixed frame 1;

[0023] The adjustment assembly 2 includes a sleeve 201 , the bottom of the sleeve 201 is sleeved with a sleeve rod 202 , and one end of the sleeve rod 202 is mounted with a pressure wheel 3 via a rotating shaft. An annular air cushion 203 is sleeved on the outer periphery of the sleeve rod 202 in the sleeve 201 .

[0024] A positioning seat 4 is disposed on one side of the fixing frame 1 , and a connecting seat 5 is disposed on the other side of the fixing frame 1 .

[0025] In this embodiment, Figure 1 As shown, the positioning seat 4 and the connecting seat 5 facilitate the fast splicing of the fixing frame 1 to adapt to different paper cutter installation environments.

[0026] A compression spring 204 is provided at the top of the sleeve rod 202 in the sleeve 201 , and an air nozzle 205 is provided at one side of the sleeve 201 .

[0027] In this embodiment, Figure 2 As shown, the sleeve rod 202 is pushed by the elastic force of the compression spring 204, which can push the pressing wheel 3 to slide downward to ensure the friction with the paper, and the annular air cushion 203 can be deflated through the air nozzle 205.

[0028] The control component 6 includes a fixing seat 601 , an elastic body 602 is disposed on the surface of the fixing seat 601 , and a one-way valve 603 is disposed at the air inlet end of the fixing seat 601 .

[0029] In this embodiment, Figure 4 As shown, by pressing the elastic body 602 , the external air can be sucked into the annular air cushion 203 by utilizing the elastic deformation generated.

[0030] The positioning seat 4 includes a ball 401 , and the connecting seat 5 includes a magnet 501 .

[0031] In this embodiment, Figure 3 As shown, the balls 401 and the magnets 501 are used to facilitate magnetic attraction and quickly complete the splicing and assembly of the pressing wheels 3 .

[0032] It should be noted that the utility model is a conveying pressure wheel for a paper cutter. When working, the operator first inserts the ball 401 into the connecting seat 5 in sequence according to the environment inside the paper cutter, and uses the magnetic force of the magnet 501 to attract the ball, which can achieve the effect of quick splicing and combination. Then the fixing frame 1 is installed in the paper cutter by bolts for use. During use, the elastic force of the compression spring 204 is used to push the sleeve rod 202 down, which can ensure the use effect of the pressure wheel 3. When the pressure wheel 3 needs to be replaced or cleaned of waste scraps, the elastic body 602 can be pressed to draw external air into the annular air cushion 203 through the elastic deformation generated, and the deformation generated by inflation is used to push the sleeve rod 202 upward, thereby lifting the pressure wheel 3, so as to increase the cleaning space inside the paper cutter. After the operation is completed, the annular air cushion 203 can be deflated through the air nozzle 205 to complete the reset. The overall operation is simple, the use is more flexible and reliable, and the practical value is high.
