DETAILED DESCRIPTION
[0030] The preferred specific implementation methods for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.
[0031] See also Figure 1-Figure 7 The utility model provides a hot cutting pelletizer, which includes a cutting device 001 and a conveying device 002.
[0032] The cutting device 001 includes a cutting assembly 100 for pelletizing, and the cutting assembly 100 includes a cutting knife 110 for cutting particles, and a rotating shaft 120 for limiting the cutting knife 110 is fixedly installed in the middle of the cutting knife 110, and a motor 130 for controlling the rotation of the rotating shaft 120 is fixedly installed at one end of the rotating shaft 120, and the motor 130 is fixedly installed on the rear end outer wall of the conveying box 400. Two cutting devices 001 are installed at the rear end of the conveying box 400, and the rotation directions of the two cutting assemblies 100 are opposite. The cutting knife 110 located at the left end of the inner cavity of the conveying box 400 rotates clockwise, and the cutting knife 110 located at the right end of the inner cavity of the conveying box 400 rotates counterclockwise, so that the particles fall to the inclined plate 440.
[0033] One end of the cutting assembly 100 is hinged with a protective cover 200 for protecting the cutting assembly 100. The protective cover 200 includes a shell 210. The middle of the shell 210 is provided with an inner cavity 211 for the cutting blade 110 to rotate. The edges of the shell 210 are provided with air inlets 212 for heat dissipation. The wind blowing toward the V-shaped plate 450 through the air outlet 481 drives the wind to move from the groove cavity of the ventilation groove 451 to the upper end of the inner cavity of the conveying box 400. The wind moves toward the groove cavity of the inner cavity 211 through the air inlet 212, thereby cooling the groove cavity of the inner cavity 211. A fixed block 220 is fixedly installed at one end of the shell 210. The fixed block 220 is arranged in the groove cavity of the limiting groove 431 to limit the shell 210 so that when the cutting blade 110 rotates, the shell 210 cannot rotate. A sleeve 230 is fixedly installed in the middle of the housing 210 for cooperating with the rotating shaft 120 to limit the housing 210 . The sleeve 230 is sleeved in the middle of the rotating shaft 120 .
[0034] A blocking component 300 for blocking particles is fixedly installed in the middle of the protective cover 200. The blocking component 300 includes an L-shaped baffle plate 310 for blocking particles. After the cutting knife 110 cuts the particles during rotation, the particles are driven to fall downward, and the particles adhered to the cutting knife 110 are blocked by the L-shaped baffle plate 310, so that the particles cannot enter the groove cavity of the inner cavity 211. A limit block 311 is fixedly installed at one end of the L-shaped baffle 310, and a limit block 320 for limiting the limit block 311 is installed at one end of the L-shaped baffle 310. The limit block 320 is fixedly installed at one end of the housing 210, and a slide groove 321 for sliding the limit block 311 is provided inside the limit block 320. The groove cavity of the slide groove 321 is installed with a spring 322 for controlling the L-shaped baffle 310 to reset. When the L-shaped baffle 310 is driven to move toward the inner cavity of the slide groove 321, the limit block 320 is fixedly installed at one end of the housing 210. 11 squeezes the spring 322, so that the L-shaped baffle 310 squeezes the adhered particles, so that the particles are separated from the cutting knife 110. If the particles adhere to the surface of the L-shaped baffle 310, when the spring 322 drives the limit block 311 to reset, the limit block 311 drives the L-shaped baffle 310 to reset, so that the L-shaped baffle 310 is quickly reset. The limit block 311 contacts the inner wall of the slide groove 321, and when the L-shaped baffle 310 is driven to stop, the inertia throws the particles out of the L-shaped baffle 310, so that the particles fall toward the inclined plate 440.
[0035] A conveying device 002 for limiting the cutting device 001 is installed on the outside of the cutting device 001. The conveying device 002 includes a conveying box 400. A die head 410 for extruding particles is installed at the rear end of the conveying box 400. A discharge port 411 is opened in the middle of the die head 410, and the discharge port 411 is distributed at the left and right ends of the die head 410 to facilitate the cutting knife 110 to cut during rotation.
[0036] The rear end of the conveying box 400 is provided with a limiting hole 420 for limiting the rotation shaft 120, and a bearing for limiting the rotation shaft 120 is installed inside the limiting hole 420. The inner walls of the left and right ends of the conveying box 400 are fixedly installed with limiting blocks 3 430, and the middle of the limiting block 3 430 is provided with a limiting groove 431 for limiting the housing 210, and the fixing block 220 is fixedly arranged inside the limiting groove 431 to stabilize the housing 210. An inclined plate 440 for blocking particles is fixedly installed in the middle of the inner cavity of the conveying box 400. The cut particles fall toward the inclined plate 440. The setting of the inclined plate 440 prevents the hotter particles from falling directly to the ventilation slot 471, causing the particles to adhere to the inner wall of the ventilation slot 471. The air outlet 481 blows the falling particles toward the V-shaped plate 450, and the V-shaped plate 450 slows down the descending speed of the particles. The control component 460 drives the V-shaped plate 450 to vibrate, so that the particles are not easily adhered to the V-shaped plate 450.
[0037] A V-shaped plate 450 for preventing particles from sticking is installed at the right end of the inner cavity of the conveying box 400. The V-shaped plate 450 is composed of an upper inclined plate and a lower inclined plate. The upper inclined plate of the V-shaped plate 450 is provided with a ventilation slot 451 for ventilation, which is convenient for the wind to flow to the housing 210. A deceleration plate 452 for slowing down the falling speed of particles is fixedly installed on the lower inclined plate of the V-shaped plate 450. A T-shaped slider 453 for limiting the V-shaped plate 450 in cooperation with the conveying box 400 is fixedly installed in the middle of the right end of the V-shaped plate 450. A T-shaped groove cavity for the T-shaped slider 453 to slide up and down is opened on the right inner wall of the conveying box 400, thereby limiting the V-shaped plate 450.
[0038] A control component 460 for controlling the vibration of the V-shaped plate 450 is installed at one end of the V-shaped plate 450, and the control component 460 includes a cam 461 for controlling the up and down movement of the V-shaped plate 450, and a rotating shaft 462 for controlling the rotation of the cam 461 is fixedly installed at one end of the cam 461, and a motor 463 for controlling the rotation of the rotating shaft 462 is fixedly installed at one end of the rotating shaft 462. When the motor 463 is started, the motor 463 drives the rotating shaft 462 to rotate, and then drives the cam 461 to rotate, so that the protrusion of the cam 461 touches the V-shaped plate 450, driving the V-shaped plate 450 to move up and down, so as to vibrate the particles on the upper end of the V-shaped plate 450, slow down the descending speed of the particles and avoid the particles from sticking.
[0039] A ventilation pipe 470 for wind transporting particles is fixedly installed at the lower end of the conveying box 400. A ventilation slot 471 for ventilation is provided inside the ventilation pipe 470. A guide plate 473 for guiding wind is fixedly installed at the left end of the ventilation pipe 470. The guide plate 473 is located at the bottom of the ventilation pipe 480 and is used to guide the wind inside the ventilation slot 471 to the inside of the ventilation pipe 480. A discharge port 472 for particles to fall is provided in the middle of the ventilation pipe 470. The particles falling due to the vibration of the V-shaped plate 450 fall into the ventilation slot 471 through the discharge port 472 for transportation. A ventilation pipe 480 for blowing particles on the upper end of the inclined plate 440 is fixedly installed at the left end of the conveying box 400. An air outlet 481 for blowing air toward the upper end of the inclined plate 440 is opened at one end of the ventilation pipe 480, so that when the particles fall toward the inclined plate 440, they are blown toward the V-shaped plate 450 by the wind. The V-shaped plate 450 is driven to vibrate by the control component 460 to slow down the falling of the particles, so that the particles can fall into the groove cavity of the ventilation groove 471 after being cooled.

In addition, any non-creative modifications made to the utility model by those skilled in the art without making creative work still fall within the scope of protection of the utility model.
