[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0022] See also Figures 1 to 8 As shown, the present invention provides an electronic auxiliary material cutting device, comprising a fixed base 1, a transport part 2 is provided at one end of the upper part of the fixed base 1, and the transport part 2 transports the cut raw materials quantitatively; The upper part of the fixed base 1 is provided with a cutting part 3, and the cutting part 3 includes a mounting seat 301, a cutting cylinder 302, an extrusion seat 303, a cutting seat 304 and a docking seat 305. The lower part of the mounting seat 301 is fixedly connected to the upper part of the fixed base 1, the upper end of the cutting cylinder 302 is fixedly connected to the upper end inside the mounting seat 301, the cutting cylinder 302 is connected to the mains, the extrusion seat 303 is fixedly connected to the output end of the cutting cylinder 302, the cutting seat 304 is fixedly connected to the lower end of the extrusion seat 303, the docking seat 305 is fixedly connected to the lower end inside the mounting seat 301, and the interior of the upper end of the docking seat 305 matches the lower end of the cutting seat 304: A storage portion 4 is also provided on the upper portion of the fixed base 1 , and the storage portion 4 stores both the cut raw materials and the cut waste.

[0023] Specifically, firstly, the material transport roll 406 with the auxiliary material rolled up and the empty material receiving roll 407 are installed on the corresponding installation shaft 402, then one end of the auxiliary material is passed through the interior of the transport part 2, and then one end of the auxiliary material is fixed inside the empty material receiving roll 407, so as to complete the transportation and fixing of the auxiliary material; During the rotation of the transport unit 2, the auxiliary material inside the material transport roll 406 can be pulled out and moved. At this time, the auxiliary material is at the lower end of the cutting unit 3. When the auxiliary material needs to be cut, the transport unit 2 needs to stop transporting, and then the cutting seat 304 is driven to move downward through the output end of the cutting cylinder 302, so that the cutting seat 304 first squeezes and fixes the auxiliary material on the upper end of the docking seat 305. As the cutting cylinder 302 continues to move downward, the cutting seat 304 squeezes and cuts the squeezed and fixed auxiliary material. At this time, the cut part of the auxiliary material is affected by gravity and falls into the collection box below through the docking seat 305 for collection. At this point, the cutting and collection of the auxiliary material is completed. At the same time, the winding motor 405 drives the material collection roll 407 to rotate, which can be used to wind up the auxiliary material remaining after cutting, thereby realizing waste material storage and processing.

[0024] See also Figures 2 to 4As shown, the cutting seat 304 includes a mounting plate 3041, an elastic extrusion piece 3042, an extrusion sleeve 3043 and a cutting blade 3044. The upper end of the mounting plate 3041 is fixedly connected to the lower end of the extrusion seat 303, the upper end of the elastic extrusion piece 3042 is fixedly connected to the lower end of the mounting plate 3041, and the upper end of the extrusion sleeve 3043 is fixedly connected to the lower end of the elastic extrusion piece 3042, so that when the mounting plate 3041 moves with the extrusion seat 303, the mounting plate 3041 drives the elastic extrusion piece 3042 and the extrusion sleeve 3043 to move toward the docking seat 305, so that the extrusion sleeve 3043 first contacts the auxiliary material at the upper end of the docking seat 305, and then continues to move downward with the mounting plate 3041, so that the elastic extrusion piece 3042 and the extrusion sleeve 3043 are moved toward the docking seat 305. The extrusion piece 3042 applies pressure to the extrusion sleeve 3043, and the extrusion sleeve 3043 extrudes and fixes the auxiliary material. The upper end of the cutting blade 3044 is fixedly connected to the middle part of the mounting plate 3041, and the outer edge of the cutting blade 3044 is slidingly connected to the inner side of the extrusion sleeve 3043. Then, as the mounting plate 3041 continues to move downward, the mounting plate 3041 drives the cutting blade 3044 to move downward along the inside of the extrusion sleeve 3043 until the cutting blade 3044 contacts the fixed auxiliary material. Through the cooperation between the cutting blade 3044 and the inside of the docking seat 305, the cutting blade 3044 can be inserted into the inside of the docking seat 305. At this time, the auxiliary material is cut by the cutting blade 3044.

[0025] See also Figure 8 As shown, the cutting direction of the cutting blade 3044 is set to be inclined. Through the inclined cutting end, the inclined tip of the cutting blade 3044 can first be inserted into the interior of the auxiliary material to fix the four sides, so as to realize the cutting positioning of the auxiliary material, and then the cutting blade 3044 can move downward to squeeze and cut the auxiliary material through the subsequent inclined surface. The cutting on the inclined surface can reduce the cutting pressure of the cutting blade 3044 on the auxiliary material to ensure the cutting of the auxiliary material.

[0026] See also Figure 2 and Figure 4 As shown, a rubber pad is arranged on the outer edge of the lower end of the extrusion sleeve 3043, and the rubber pad cooperates with the docking seat 305. The rubber pad can utilize the flexibility of the rubber pad itself when the lower end of the extrusion sleeve 3043 contacts the auxiliary material, so as to avoid rigid extrusion damage to the auxiliary material caused by the downward pressure of the extrusion sleeve 3043. At the same time, the rubber pad can also increase the friction between the extrusion sleeve 3043 and the auxiliary material, so as to avoid the auxiliary material from moving and dislocating due to too small friction when the cutting blade 3044 moves downward to extrude and cut the auxiliary material, thereby causing cutting dislocation.

[0027] See also Figures 2 to 4As shown, the transport unit 2 includes a transport motor 201, a driving wheel 202, a transmission belt 203, a driven wheel 204, an extrusion frame 205, an elastic reset member 206 and a limit wheel 207. The transport motor 201 is fixedly connected to the fixed base 1, the transport motor 201 is connected to the mains, the driving wheel 202 is fixedly connected to the output end of the transport motor 201, one side of the transmission belt 203 is in contact with the outer edge of one end of the driving wheel 202, and the outer edge of one end of the driven wheel 204 is in contact with the other side of the transmission belt 203. The driving wheel 202 is driven to rotate by the transport motor 201, and the rotation of the driving wheel 202 transmits power to the driven wheel 204 through the transmission belt 203, driving the driven wheel 204 to rotate. The extrusion frame 205 is slidably arranged on the fixed base 1. Inside the fixed base 1, an elastic reset member 206 is arranged between the extrusion frame 205 and the fixed base 1, and two limiting wheels 207 are arranged at the lower end of the extrusion frame 205. The two limiting wheels 207 cooperate with the driving wheel 202 and the driven wheel 204, and the extrusion frame 205 is elastically squeezed by the elastic reset member 206, so that the extrusion frame 205 drives the limiting wheel 207 to apply pressure in the direction of the driving wheel 202 and the driven wheel 204, so that the limiting wheel 207 squeezes the auxiliary material between the driving wheel 202 and the driven wheel 204, thereby increasing the friction of the auxiliary material between the limiting wheel 207 and the driving wheel 202 and the driven wheel 204, avoiding slippage in the transportation of the auxiliary material, and ensuring the accuracy of the transportation distance of the auxiliary material by the driving wheel 202 and the driven wheel 204.

[0028] See also Figure 3 and Figure 4 As shown, limiting plates are provided on both sides of the limiting wheel 207, and the limiting plates cooperate with the two ends of the corresponding driving wheel 202 and the driven wheel 204. The limiting plates are used to limit the two sides of the auxiliary materials to prevent the auxiliary materials from deviating during transportation and getting stuck in the two sides of the driving wheel 202 and the driven wheel 204, thereby improving the stability of the equipment operation.

[0029] See also Figure 4 As shown, anti-skid sleeves are provided on the outer edges of the limiting wheel 207, the driving wheel 202 and the driven wheel 204. The anti-skid sleeves increase the friction of the outer edges of the limiting wheel 207, the driving wheel 202 and the driven wheel 204 on the auxiliary materials, further avoiding slipping and further ensuring the transportation of the auxiliary materials and the accuracy of transportation.

[0030] See also Figures 2 to 4As shown, a limiting groove matching the outer edge of the lower end of the docking seat 305 is provided inside the extrusion frame 205, and the outer edge of the docking seat 305 can provide guidance and limitation for the vertical sliding of the extrusion frame 205, so as to ensure that the extrusion frame 205 is elastically extruded by the elastic reset member 206 and exerts pressure in the vertical upward direction, thereby preventing the limiting wheel 207 from driving the extrusion frame 205 to move horizontally when rotating, causing the movement of the limiting wheel 207 to be staggered with the corresponding active wheel 202 and driven wheel 204, so that the auxiliary material loses the extrusion force, resulting in the loss of accuracy in the transportation of the auxiliary material.

[0031] See also Figures 1 to 3 as well as Figures 5 to 7 As shown, the storage portion 4 includes a storage rack 401, a mounting shaft 402, a fixed block 403, an elastic fixing member 404, a winding motor 405, a material transport roll 406 and a material receiving roll 407. The lower end of the storage rack 401 is fixedly connected to the upper part of the fixed base 1, and two mounting shafts 402 are rotatably arranged on the upper part of the storage rack 401. Two fixed blocks 403 are arranged, and the two fixed blocks 403 are slidably connected to the inside of one end of the mounting shaft 402. The elastic fixing member 404 is arranged between the fixed blocks 403. The winding motor 405 is fixedly connected to the storage rack 401, and the winding motor 405 is connected to the mains. One end of the winding motor 405 is fixedly connected to one end of a corresponding mounting shaft 402, the material transport roll 406 is arranged on the outer edge of the other end of the corresponding mounting shaft 402, and the material receiving roll 407 is arranged at the other end of the mounting shaft 402 fixed with the winding motor 405. When the material transport roll 406 and the material receiving roll 407 are installed into the outer edge of the corresponding mounting shaft 402, the elastic fixing member 404 always applies a force to the fixing block 403 to extend the mounting shaft 402, so that the fixing block 403 always applies a force to the inside of the material transport roll 406 and the material receiving roll 407, and the fixing block 403 fixes the inside of the material transport roll 406 and the material receiving roll 407, thereby preventing the material transport roll 406 and the material receiving roll 407 from falling off the corresponding mounting shaft 402; The winding motor 405 drives the corresponding mounting shaft 402 to rotate, so that the rotation of the mounting shaft 402 drives the material collection roll 407 installed on the outer edge thereof to rotate, so as to roll up and collect the cut auxiliary materials.

[0032] See also Figure 7 As shown, one side of the fixing block 403 is arranged as an inclined surface, which matches with the center of the material transport roll 406 and the material receiving roll 407. When the material transport roll 406 and the material receiving roll 407 are installed into the outer edge of the corresponding installation shaft 402, the inclined surface of the fixing block 403 is first squeezed to make the fixing block 403 shrink into the interior of the installation shaft 402, so that the material transport roll 406 and the material receiving roll 407 can be installed and fixed more conveniently.

[0033] The working principle of the present invention is as follows: first, the material transport roll 406 with the auxiliary material rolled up and the empty material receiving roll 407 are installed on the corresponding installation shaft 402, and then one end of the auxiliary material is passed through the interior of the transport part 2, and then one end of the auxiliary material is fixed inside the empty material receiving roll 407 to complete the transportation and fixation of the auxiliary material. During the rotation of the transport part 2, the auxiliary material inside the material transport roll 406 can be pulled out and moved. At this time, the auxiliary material is at the lower end of the cutting part 3. When the auxiliary material needs to be cut, the transport part 2 needs to stop transporting, and then the auxiliary material is transported by The output end of the cutting cylinder 302 drives the cutting seat 304 to move downward, so that the cutting seat 304 first squeezes and fixes the auxiliary material on the upper end of the docking seat 305. As the cutting cylinder 302 continues to move downward, the cutting seat 304 squeezes and cuts the squeezed and fixed auxiliary material, and at the same time, the cut part of the auxiliary material can fall into the collection box below through the docking seat 305 for collection. At this point, the cutting of the auxiliary material is completed. At the same time, the winding motor 405 drives the material collection reel 407 to rotate to be able to wind up the auxiliary material remaining after cutting.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
