[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See Figures 1 to 6 The embodiment of the utility model provides a rapid shearing device for mixed rubber, including a shearing frame 2, an adjusting frame 5 and a shearing assembly 6.

[0027] See Figure 3The shearing assembly 6 includes two sets of vertical frames 61, a shearing setting frame 63 is provided on the top of the vertical frame 61, and a set of lifting electric cylinders 64 are respectively provided at the front and rear ends of the shearing setting frame 63, a fixed knife holder 65 is provided at the bottom of the lifting electric cylinder 64, and a shearing blade 66 is provided at the bottom of the fixed knife holder 65. A wiping device 67 is provided at the lower end of the vertical frame 61 facing the shearing blade 66. The shearing assembly 6 fixes the installation of the shearing setting frame 63 through the two sets of vertical frames 61 to realize the support setting of the lifting electric cylinder 64. The bottom of the lifting electric cylinder 64 is fixed to the connection with the fixed knife holder 65, driving the fixed knife holder 65 to realize the operation control of the shear blade 66, and the lifting electric cylinder 64 is used to adjust the up and down movement of the shear blade 66 to ensure the stability of the shear blade operation. In the process of the shear blade 66 completing the shearing and rising, the wiping device 67 wipes and cleans the colloid attached to its surface to ensure the performance of the shear blade 66.

[0028] See Figure 4 and Figure 5 A group of abutment seats 671 are respectively provided at the left and right ends of the bottom of the inner cavity of the wiping device 67, and a strong spring group 672 is respectively provided inside the abutment seat 671. A group of scraper holders 673 are respectively provided inside the strong spring group 672. A group of wiping blocks 674 are respectively provided on the top of the scraper holder 673, and a group of scraper knives 675 are respectively provided at the bottom of the scraper holder 673. A group of water outlet valve seats 676 are respectively provided at the left and right ends of the bottom of the wiping device 67. A number of high-pressure water outlets 677 are evenly provided at the bottom of the two groups of water outlet valve seats 676. The inner cavity of the wiping device 67 establishes support for the strong spring group 672 by setting the abutment seat 671. The strong spring group 672 includes multiple groups of strong springs of the same specifications, which can cooperate with the abutment seat 671 to realize elastic support for the scraper frame 673, establish contact between the scraper knife 675 and the shear blade 66, and the scraper knife 675 and the shear blade 66 are set in the same direction and slightly inclined at an angle, which can quickly scrape off the viscous colloid on the surface of the shear blade 66, and cooperate with the wiping block 674 to realize the wiping process of the shear blade 66. A diversion pipe is provided in the wiping device 67 to supply water to two groups of high-pressure water outlets 677. Opening the two groups of water outlet valve seats 676 can cooperate with the high-pressure water outlet 677 to flush the shear blade 66.

[0029] See Figure 2The front end and bottom of the adjustment frame 5 are set as a fixed seat 51, and a support frame 52 is provided in the fixed seat 51. A transverse seat 53 is provided at the top and rear end of the support frame 52. A filter screen cover 54 is provided on the top panel of the transverse seat 53. Several groups of DC fans 55 are provided at the bottom of the filter screen cover 54. A heating resistor 56 is provided below the DC fan 55. A circuit setting frame 58 is provided in front of the heating resistor 56. An air outlet 57 is provided at the bottom of the transverse seat 53. The adjustment frame 5 is fixed to the front end of the fixed frame 4 through the fixed seat 51 to achieve stable support of the fixed frame 4 on the adjustment frame 5. The fixed seat 51 realizes the setting of the transverse seat 53 through the support frame 52. The transverse seat 53 A filter screen 54 is provided at the top to reduce the negative impact of dust carried by the DC fan 55 during the operation of the airflow and on its components, thereby extending the continuous operation time of the DC fan 55 and reducing the difficulty of cleaning the components of the adjustment frame 5. After the airflow enters the inner cavity of the adjustment frame 5, it can be continuously blown onto the mixed rubber strip through the air outlet 57. If the temperature of the mixed rubber strip is high, the airflow is used to lower the temperature of the mixed rubber strip and reduce the adhesive adhesion of the shear blade 66. If the temperature of the mixed rubber strip is low, the heating resistor 56 is turned on to heat the airflow, so that the air outlet 57 blows hot air toward the mixed rubber strip, reducing the cutting difficulty of the shear blade 66 and ensuring the efficiency of the shearing work.

[0030] See Figure 3 A liquid storage tank 62 is provided in front of the front end frame 61, and a liquid guide tube is provided at the bottom of the liquid storage tank 62. The liquid guide tube is connected to the wiping device 67. The liquid storage tank 62 can store degumming liquid, and the degumming liquid is transmitted to the wiping device 67 by using the liquid guide tube. It can be sprayed on the shearing blade 66 in conjunction with its conduit, water outlet valve seat 676 and high-pressure outlet 677 to remove the glue attached to its surface and difficult to be scraped and rinsed. The viscous colloid is further ensured to further ensure the performance of the shearing blade 66.

[0031] A set of embedding grooves 68 are respectively provided on the fixing frame 4 opposite to the shear blade 66. The embedding grooves 68 are arranged opposite the front and rear edges of the shear blade 66. When the shear blade 66 is pressed down, its front and rear edges are stuck into the embedding grooves 68, providing absolute contact space between the shear blade 66 and the mixed rubber strip on the conveyor belt 3, thereby ensuring the complete cutting operation of the mixed rubber strip.

[0032] The inclination angle of the left end edge of the shearing blade 66 is set to be 1 degree greater than the inclination of the right end edge. During the shearing process when the shearing blade 66 contacts the mixed rubber strip and continues to press down, due to the larger inclination angle of the left end edge of the shearing blade 66, the rubber strip at the left end of the shearing blade 66 can be quickly prevented from continuing to move to the right, so that the shearing blade 66 can quickly cut off the mixed rubber strip.

[0033] The cutting edges on both sides of the shear blade 66 are sprayed with a hard alloy coating. Providing the hard alloy coating can improve the structural performance of the shear blade 66, reduce its adhesion to the colloid, and improve the practicality of the shear blade.

[0034] The correction component 7 includes two sets of fixed vertical plates 71. The outer end of the front fixed vertical plate 71 is provided with a first adjusting cylinder 72. The protruding end of the first adjusting cylinder 72 passes through the fixed vertical plate 71 and is provided with a first cross bar 73. The first cross bar 73 is provided with a first ring 74. The bottom of the first ring 74 is provided with a front correction plate 75. The outer end of the rear fixed vertical plate 71 is provided with a second adjusting cylinder. The protruding end of the second adjusting cylinder passes through the fixed vertical plate and is provided with a second cross bar. The second cross bar is provided with a second ring. The bottom of the second ring is provided with a rear correction plate 76. The correction component 7 is fixed by the fixed vertical plate 71. It is arranged on two sets of fixed frames 4 to establish support for the first cross bar 73 and the second cross bar. The first cross bar 73 is arranged parallel to the second cross bar. The front end of the first cross bar 73 is provided with a first ring 74 to establish the installation of the front correcting plate 75, which can move the rubber strip moved to the front edge of the shearing frame 2 backward. The rear end of the second cross bar is provided with a second ring to establish the installation of the rear correcting plate 76, which can move the rubber strip moved to the rear edge of the shearing frame 2 forward, so that the rubber strips that have been cut can continue to run backward in the center of the conveyor belt 3 to the next production line.

[0035] The embodiment of the present invention provides a rapid shearing device for mixed rubber. The production line places the processed mixed rubber strips on the conveyor belt 3, detects the temperature of the mixed rubber strips by a temperature detection device, and determines whether the temperature needs to be adjusted by the control center. The DC fan 55 on the adjustment frame 5 is controlled to cooperate with the heating resistor wire 56 to adjust the temperature of the mixed rubber strips, so that the subsequent shearing component 6 can perform shearing processing on the mixed rubber strips. The sheared rubber strips are continuously sent to the next production line by the conveyor belt 3.

[0036] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto.
