BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0010] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0011] Embodiment 1:
[0012] like Figure 1 As shown, the utility model discloses a mixed rubber cutting device, comprising a frame 1 and a cutting platform 2 arranged on the frame 1, a crossbeam 13 is arranged on the frame 1 above the cutting platform 2, vertically upward guide grooves 3 are arranged on the frame 1 at both ends of the cutting platform 2, the guide grooves 3 are arranged oppositely, a cutting knife 4 is arranged in the guide grooves 3, connecting ears 5 are arranged on the upper end surfaces of both ends of the cutting knife 4, a connecting rod 6 is arranged on the connecting ear 5 through a pin, a through hole 7 is arranged on the crossbeam 13 at the corresponding position of the connecting rod 6, the connecting rod 6 passes through the through hole 7 and extends to the top of the crossbeam 13, and a A limit plate 8 is provided, and a compression spring 9 is sleeved on the connecting rod 6 between the limit plate 8 and the cross beam 13. A power mechanism 10 is provided on the cross beam 13. The output shaft 11 of the power mechanism 10 is horizontally arranged, and a cam 12 is arranged on the output shaft 11 of the power mechanism 10, and the cam 12 contacts the upper edge of the cutting knife 4; two synchronously moving output shafts 11 are arranged on the power mechanism 10, and the horizontal heights of the two output shafts 11 are consistent, the output shafts 11 are respectively located above both sides of the cutting knife 4, a cam 12 is arranged on each output shaft 11, and there is a relative angle difference between the two cams 12.
[0013] The cutting platform 2 is connected to the conveying mechanism of the sheet-like mixed rubber, and the mixed rubber is quantitatively conveyed to the cutting platform 2 by the conveying mechanism. The conveying mechanism is an existing known device, and the specific structure is not repeated. Generally, the conveying power is provided by the guide roller to convey the sheet-like mixed rubber forward. Guide grooves 3 are set on both sides of the frame 1, and the cutting knife 4 is set in the guide groove 3, so the cutting knife 4 can only be raised and lowered in the vertical direction, and the cutting position can be accurately defined, and the cutting stability is high. The two ends of the cutting knife 4 are rotatably set with connecting rods 6 through the connecting ears 5. The connecting rod 6 passes through the crossbeam 13 and is provided with a compression spring 9. Under the action of the compression spring 9, the connecting rod 6 always generates a numerical upward pulling force on the cutting knife 4. After the cutting is completed, the cutting knife 4 is lifted by the connecting rod 6. The power mechanism 10 can be a combination of an electric motor and a gear box, and consists of two synchronously moving output shafts 11, and the rotation speed of the two output shafts 11 is the same. Two cams 12 are arranged on the output shaft 11. The relative angle difference between the cams 12 refers to the angle between the apex of the two cams 12 and the line connecting the center of the corresponding output shaft 11. That is, the apex of one cam 12 contacts the top surface of the cutter 4. At this time, when the cutter 4 at this end is pushed to the bottom, the apex of the other cam 12 does not contact the top surface of the cutter 4. Therefore, this end of the cutter 4 has not reached the bottom, and the cutter 4 is in an inclined state, which is conducive to cutting the mixed rubber and can reduce cutting energy consumption.
[0014] The spacing between the guide grooves 3 is smaller than the length of the cutting blade 4, and the sum of the spacing between the guide grooves 3 and the depth of the two guide grooves 3 is greater than the length of the cutting blade 4. Both ends of the cutting blade 4 are located in the guide groove 3, and the guide groove 3 is used to limit the cutting blade 4 to only be able to move up and down, and the two ends of the cutting blade 4 do not contact the end surface inside the guide groove 3, and there is a certain gap. When the cutting blade 4 is tilted, the end of the cutting blade 4 will not interfere with the guide groove 3, and the operation is stable and smooth.
[0015] The structure of the cam 12 is as follows: it includes a semicircle and an arch, wherein the diameter of the semicircle is equal to the chord length of the arch, and the diameter of the semicircle coincides with the chord of the arch. After the output shaft 11 is connected to the cam 12, the center of the output shaft 11 coincides with the center of the semicircle. The cam 12 adopts a combination of a semicircle and an arch. During the rotation of the cam 12, one of the cams 12 first rotates to the semicircle, at which time the cutting knife 4 at this location is pushed to the bottom and contacts the cutting platform 2, and then the other cam 12 gradually rotates to the semicircle and contacts the cutting knife 4, and the cutting knife 4 at this location is also pushed to the bottom. In this process, the semicircular parts of the two cams 12 are in contact with the top surface of the cutting knife 4, so the cutting knife 4 is pushed to the bottom and kept in a horizontal state, which can ensure the reliability of cutting. Then the lifting process is also one end gradually rising, and the other end gradually rising afterwards. This process can make the cutting and rising of the cutting knife 4 more labor-saving and low energy consumption.
[0016] The relative angle difference between the two cams 12 is 30°-90°, and 30° is generally selected.
