Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1
[0022] according to Figure 1-Figure 4 As shown, a cutting device for producing and processing erasers comprises a cutting table 1, on which is disposed an extrusion assembly 2 for producing erasers, on the right side of the extrusion assembly 2 is disposed a fixed-length conveying mechanism 4 for horizontally conveying the erasers, on the right side of the fixed-length conveying mechanism 4 is disposed a quick-cutting mechanism 5 for cutting the erasers, after the eraser block 3 is extruded through the extrusion assembly 2, it will extend into the interior of the quick-cutting mechanism 5 at the left and right sides of the fixed-length conveying mechanism 4, and then the quick-cutting mechanism 5 will cut the eraser block 3 to equal lengths.
[0023] Specifically, the fixed-length conveying mechanism 4 includes a first mounting seat 401 and a second mounting seat 402 fixedly mounted on the cutting table 1. The first mounting seat 401 is provided with a conveying component 403 and a driving motor 404 for conveying the rubber block 3. After the rubber block 3 is extruded, the conveying component 403 will automatically convey it to the interior of the quick cutting mechanism 5 for strip cutting.
[0024] Specifically, the quick cutting mechanism 5 includes a mounting protrusion 501 fixedly mounted on the cutting table 1, the right side of the upper end of the mounting protrusion 501 is set to be rounded, and after cutting is completed, the rubber strip will fall into the inside of the receiving box 510 along the rounded corner, thereby realizing automatic unloading, a movable bracket 502 is movably mounted on the mounting protrusion 501, and a cutting tool 503 is detachably mounted on the movable bracket 502, and side wall grooves 504 are symmetrically provided on the front and rear sides of the mounting protrusion 501, and the movable bracket 502 is slidably connected to the side wall groove 504, and a driving member 505 for driving the movable bracket 502 to move up and down is provided inside the side wall groove 504, and a cutting groove 506 matching the cutting tool 503 is provided on the upper end of the mounting protrusion 501. A rectangular cavity 507 is provided inside the mounting protrusion 501, and a liquid storage tank 508 is arranged inside the rectangular cavity 507. The liquid storage tank 508 is connected to the interior of the cutting groove 506. The interior of the liquid storage tank 508 is filled with lubricating liquid. When the lubricating liquid is squeezed upward through the liquid pushing component 509, it will enter the interior of the cutting groove 506, so that the outside of the cutting tool 503 is kept lubricated. The interior of the liquid storage tank 508 is provided with a liquid pushing component 509 for squeezing the lubricating liquid upward. A receiving box 510 for receiving the rubber strip is provided on the right side of the mounting protrusion 501. When the rubber block 3 extends to the bottom of the cutting tool 503 under the action of the fixed-length conveying mechanism 4, the movable bracket 502 will move downward quickly under the action of the driving member 505, thereby completing the cutting.
[0025] More specifically, the conveying assembly 403 includes a driving roller movably mounted on the first mounting seat 401, a driven roller movably mounted on the second mounting seat 402, a conveyor belt is arranged between the driving roller and the driven roller, and distance measuring assemblies 405 for measuring the moving distance of the rubber block 3 are symmetrically arranged on the front and rear sides of the conveyor belt. The distance measuring assembly 405 is electrically connected to the driving motor 404 through a wire. When the rubber block 3 moves horizontally following the conveyor belt, the distance measuring assembly 405 will measure the moving distance of the rubber block 3 in real time. The driving motor 404 is connected to the driving roller in a transmission connection. When the driving roller rotates clockwise, the rubber block 3 will move horizontally to the right.
[0026] In this embodiment, Figure 1 As shown, after the extrusion component 2 extrude the rubber raw material outward in the form of a rubber block 3 (the production and processing of rubber is a common technical content in the prior art, and this application mainly improves the rubber cutting step, so the specific production process of the rubber will not be repeated), it will fall onto the conveyor belt.
[0027] Next, the conveyor belt will move horizontally to the right under the action of the driving roller. During the movement of the conveyor belt, the rubber block 3 will be pulled to move synchronously to the right, so that the right end of the rubber block 3 extends to the bottom of the movable bracket 502. Next, the movable bracket 502 will move downward rapidly under the action of the driving member 505. During the downward movement of the movable bracket 502, the cutting tool 503 will cut the rubber block 3, thereby cutting the rubber block 3 into rubber strips, and then the rubber strips will fall into the inside of the receiving box 510.
[0028] Moreover, if Figure 2 As shown, when the rubber block 3 moves horizontally to the right, the distance measuring component 405 will automatically measure the moving distance of the rubber block 3 in real time. When the moving distance reaches the preset length, the driving motor 404 will automatically stop rotating, thereby realizing fixed-length feeding and flexibly adjusting the cutting width of the rubber strip.
[0029] In addition, if Figure 4 As shown, the cutting tool 503 will extend into the cutting groove 506 during the process of cutting the rubber block 3, and there is lubricating fluid inside the cutting groove 506, so the surface of the cutting tool 503 will always remain smooth, which can effectively avoid the cutting process being affected by the cutting tool 503 becoming dry.
[0030] This embodiment, by setting a fixed-length conveying mechanism 4 and utilizing the cooperation between the conveying component 403 and the distance measuring component 405, can help the staff quickly adjust the cutting width of the rubber strip and automatically complete equidistant cutting. Moreover, the total extrusion length of the rubber block 3 can be counted, which is convenient for calculating the loss rate in the eraser production process. In addition, this embodiment, by setting a fast cutting mechanism 5 and utilizing the cooperation between the cutting groove 506 and the liquid storage tank 508, can automatically apply lubricant to the surface of the cutting tool 503, which can effectively prevent the surface of the cutting tool 503 from becoming dry, thereby ensuring that the cutting tool 503 is always in a smooth state during cutting, and can effectively improve the flatness of the incision.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
