[0011] Preferably, the shearing mechanism also includes a knife lubrication box, and the knife lubrication box is composed of an L-shaped cavity facing the side knife and a liquid storage cavity on the back of the L-shaped cavity, wherein both ends of the L-shaped cavity are provided with a slide groove, and the interior of the slide groove is slidably connected with a slider through a reset spring, and the inner and outer sides of the side knife are respectively provided with a sponge knife lubrication roller 2 and a sponge knife lubrication roller 1, and both ends of the sponge knife lubrication roller 2 and the sponge knife lubrication roller 1 are connected to each other through a square connecting tube, and the middle position of the outer side of the square connecting tube is fixedly connected to the slider, and the interior of the liquid storage cavity is equipped with a liquid pump, and the output end of the liquid pump is connected to the square connecting tube through a connecting hose.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the process of conveying the mixed rubber strip on the conveyor belt, the mixed rubber strip moves from the inclined surface of the trapezoidal receiving seat to the trapezoidal receiving seat, and then the mixed rubber strip is sheared by the shearing mechanism.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example

[0028] like Figures 1 to 9As shown, a shearing device for processing mixed rubber includes a device body 100, a conveyor belt 600 for conveying mixed rubber is installed on the top of the device body 100, and a conveyor belt 700 for collecting the mixed rubber after shearing is installed at one end of the device body 100, a receiving mechanism 500 for collecting dripping liquid and applying it on the conveyor belt 600 is fixedly connected to the device body 100 at the top surface of the conveyor belt 600, and a shearing mechanism 400 for shearing the mixed rubber is installed directly above the conveyor belt 600 through a support frame, and both sides of the receiving mechanism 500 on the top of the conveyor belt 600 are symmetrically equipped with guide mechanisms 300 for guiding the mixed rubber during transportation, and The front end of the equipment body 100 is equipped with a controller 200 for controlling the guiding mechanism 300, the shearing mechanism 400, the conveyor belt 1 600 and the conveyor belt 2 700. When in use, the guiding mechanism 300, the shearing mechanism 400, the conveyor belt 1 600 and the conveyor belt 2 700 are controlled by the controller 200 to operate, and then the mixed rubber strips are conveyed by the conveyor belt 1 600, and the mixed rubber strips are guided and limited by the guiding mechanism 300 during the conveying process. When the mixed rubber strips are sheared by the shearing mechanism 400, the conveyor belt 1 600 stops working, and then the shearing mechanism 400 shears the mixed rubber strips, and finally the sheared mixed rubber strips are conveyed by the conveyor belt 2 700.

[0029] Furthermore, conveyor belt 1 600 and conveyor belt 2 700 are both composed of two drive rollers, crawler belts mounted on the two drive rollers and a motor for driving one of the drive rollers. When in use, the drive rollers are driven to rotate by the motor, thereby driving the crawler belts to work. It is hereby explained that conveyor belt 1 600 and conveyor belt 2 700 in the present invention are only used to transport articles. How to transport articles through conveyor belts is a conventional technical means and will not be elaborated here.

[0030] Further, such as Figure 1 and Figure 2 As shown, the guide mechanism 300 includes an electric push rod 301 assembled on the front and rear sides of the equipment body 100, and a limit block 302 is fixedly connected to the output end of the electric push rod 301, and a roller 303 is rotatably connected to the limit block 302 at equal intervals along its length direction. When in use, the electric push rod 301 pushes the limit block 302 to move, thereby guiding and limiting the mixed rubber strip transported on the conveyor belt 600, and at the same time, the friction relationship between the mixed rubber strip and the guide mechanism 300 is changed by the roller 303, and the sliding friction is changed to rolling friction.

[0031] Further, such as Figure 3 and Figure 4As shown, the receiving mechanism 500 includes a trapezoidal receiving seat 501 fixed along the width direction of the equipment body 100, and a herringbone groove 502 is opened on the trapezoidal receiving seat 501 to enable the trapezoidal receiving seat 501 to communicate with each other from top to bottom. The herringbone groove 502 at the bottom of the trapezoidal receiving seat 501 is connected to a wiping roller 503 that is rotatable along its length direction. When in use, during the process of conveying the mixed rubber strip by the conveyor belt 600, the mixed rubber strip moves from the inclined surface of the trapezoidal receiving seat 501 to the trapezoidal receiving seat 501, and then the mixed rubber strip is sheared by the shearing mechanism 400. During the shearing process, the side knife 405 and the middle knife 420 shear the mixed rubber strip on the trapezoidal receiving seat 501. Cutting to prevent damage to the conveyor belt 600 during the cutting process. During the cutting process of the mixed rubber strip, the liquid dripping from the side knife 405 to the herringbone groove 502 is absorbed by the wiping roller 503, so that the liquid absorbed by the wiping roller 503 can be smeared on the surface of the conveyor belt 600 through the friction between the conveyor belt 600 and the wiping roller 503 during operation, thereby preventing the mixed rubber strip from sticking to the conveyor belt 600. It is explained here that since the mixed rubber strip is in a softened state due to heating, the mixed rubber strip is in a state of gradually cooling during its feeding and cutting process, which can easily cause the mixed rubber strip to stick to the conveyor belt 600, so it is necessary to apply liquid to the conveyor belt 600.

[0032] Further, such as Figure 5 , Figure 6 and Figure 8As shown, the shearing mechanism 400 includes a hydraulic rod 401 fixed at the middle position of the top of the support frame and a connecting plate 404 fixedly connected to the output end of the hydraulic rod 401, wherein side knives 405 are installed on both sides of the bottom of the connecting plate 404, and the two side knives 405 are distributed in an inverted eight-shaped shape, and a threaded rod 417 is rotatably connected along its length direction at the middle position of the bottom of the connecting plate 404, and a sliding block 419 is sleeved on the threaded rod 417, and a gear 418 is fixedly connected to the end of the threaded rod 417, and the top of the connecting plate 404 is equipped with a gear 403 meshing with the gear 418 through a driving motor 402, and the bottom of the sliding block 419 is fixedly connected with an intermediate knife 420, and the blade of the intermediate knife 420 is located on the same horizontal plane as the blade of the side knife 405. When in use, the connecting plate 404, the side knife 405 and the intermediate knife 420 are driven to descend by the hydraulic rod 401, thereby the conveyor belt 600 is output. The mixed rubber strips delivered are sheared. It is explained here that the prior art generally uses a blade to perform extrusion shearing on the mixed rubber strips when shearing the mixed rubber strips, which easily leads to the mixed rubber strips being in a state of being connected at the shearing point after shearing, so that the shearing of the mixed rubber strips is not thorough, thereby causing the mixed rubber strips collected after shearing to be in a state of being drawn at the shearing point. The present invention performs extrusion shearing on the mixed rubber strips by two side knives 405 in an eight-shaped shape, and at the same time, the two side knives 405 press the mixed rubber strips, and then drive the gear 1 403 to reciprocate through the drive motor 402. Since the gear 1 403 and the gear 2 418 are meshed with each other, the threaded rod 417 rotates, driving the sliding block 419 to reciprocate along the threaded rod 417, so that the mixed rubber strips can be cross-cut by the middle knife 420, preventing the mixed rubber strips from being in a state of being connected, and improving the shearing effect of the mixed rubber strips.

[0033] Further, such as Figure 7 and Fig. 9As shown, the shearing mechanism 400 also includes a knife lubrication box 406 for wetting the blade surface of the side knife 405, and the knife lubrication box 406 is composed of an L-shaped cavity 409 facing the side knife 405 and a liquid storage cavity 407 on the back of the L-shaped cavity 409, wherein both ends of the L-shaped cavity 409 are provided with a slide groove 416, and the interior of the slide groove 416 is slidably connected to a slider 411 through a return spring 410, and the inner side and outer side of the side knife 405 are respectively provided with a sponge knife lubrication roller 2 414 and a sponge knife lubrication roller 1 413, and both ends of the sponge knife lubrication roller 2 414 and the sponge knife lubrication roller 1 413 are connected to each other through a square connecting tube 412. The middle position of the outer side of the square connecting tube 412 is fixedly connected to the slider 411, and the liquid storage chamber 407 is equipped with a liquid pump 408 for extracting the liquid in the liquid storage chamber 407, and the output end of the liquid pump 408 is connected to the square connecting tube 412 through a connecting hose 415. When in use, the liquid stored in the liquid storage chamber 407 is introduced into the square connecting tube 412 through the connecting hose 415 by the liquid pump 408, and the liquid is introduced into the inside of the sponge lubricating roller 2 414 and the sponge lubricating roller 1 413 through the square connecting tube 412, so that the liquid is discharged through the sponge lubricating roller 2 414 and the sponge lubricating roller 1 413. The knife roller 413 wipes the side knife 405 and the middle knife 420, which can realize automatic cooling of the side knife 405 and the middle knife 420, and keep the side knife 405 and the middle knife 420 moist, so that the side knife 405 and the middle knife 420 are not easy to stick together when shearing the mixed rubber colloid, and the mixed rubber strip is kept stable. In addition, since the two side knives 405 are in an eight-shaped structure, when the side knife 405 descends to shear the mixed rubber strip, the side knife 405 squeezes the sponge-shaped knife roller 413, so that the outer side of the side knife 405 can be better moistened. , and at the same time, the liquid on the side knife 405 can quickly slide off the blade of the side knife 405, increasing the amount of liquid dripping from the blade of the side knife 405. In the process of squeezing the sponge lubricating roller 413, the slider 411 slides synchronously along the inside of the slide groove 416 and squeezes the reset spring 410. Then, when the side knife 405 rises after cutting the mixed rubber strip, the sponge lubricating roller 2 414 and the sponge lubricating roller 1 413 are reset under the action of the reset spring 410, so that the sponge lubricating roller 2 414 and the sponge lubricating roller 1 413 always maintain a fit state with the side knife 405.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
