A discharge pipe 5 is bolted to the outer side wall of the heating box 1, and the discharge pipe 5 is in communication with the inside of the heating box 1. The plastic particles after heating can be discharged from the inside of the heating box 1 through the discharge pipe 5. A heating mechanism 6 is arranged outside the heating box 1, and the heating mechanism 6 is located above the discharge pipe 5. The bottom end of the heating mechanism 6 is bolted to the outer side wall of the heating box 1, and the heating mechanism 6 is in communication with the inside of the heating box 1. The heating mechanism 6 is composed of a blower and a air supply pipe. The blower can be started through the control panel, and hot air is continuously supplied to the inside of the heating box 1 through the air supply pipe to heat the plastic particles.
[0030] Embodiment Two
[0031] Please refer to Figures 1-5 , the feeding part 2 is arranged on the top of the heating box 1. The feeding part 2 includes a feeding box 201 bolted to the top end of a blanking box 301. The feeding box 201 is in communication with the outside of the heating box 1, and the inside of the feeding box 201 is in communication with the inside of the blanking box 301. The structural shape of the feeding box 201 is an inverted trapezoid, and the feeding box 201 is arranged as a hollow structure. The plastic particles can be poured into the inside of the discharging part 3 by using the feeding box 201. Two inclined plates 202 are threadedly connected to the inner side wall of the feeding box 201. The two inclined plates 202 are distributed oppositely up and down on the vertical central axis of the feeding box 201. The inclined plates 202 are set at a fixed inclination angle, and the plastic particles can be sequentially discharged into the inside of the discharging part 3 for fixed-point blanking work.
[0032] Embodiment Three
[0033] Please refer to Figures 1-5, the blanking part 3 is arranged between the heating box 1 and the feeding part 2, and the interiors of the blanking part 3 and the feeding part 2 are interconnected. The plastic particles inside the feeding part 2 can be poured into the interior of the blanking box 301. The blanking part 3 is used to achieve the working purpose of fixed-point and uniform blanking. The blanking part 3 includes a blanking box 301 bolted to the top wall outside the heating box 1. The blanking box 301 is arranged as a hollow structure. A driven gear 302 is rotatably connected to the outer side wall of the blanking box 301 through a bearing. A toothless gear 303 is meshed and arranged below the driven gear 302. The inner side wall of the toothless gear 303 and the outer side wall of the blanking box 301 are rotatably connected through a bearing. A first motor 304 is bolted to the top wall outside the heating box 1. The first motor 304 can be started through the control panel. The output end of the first motor 304 extends to the outside of the toothless gear 303, and the output end of the first motor 304 is threadedly connected to the central position of the outer side wall of the toothless gear 303. The output end of the first motor 304 drives the toothless gear 303 to rotate. When the tooth groove arranged on the outer side wall of the toothless gear 303 contacts the driven gear 302, the toothless gear 303 and the driven gear 302 engage and move, and the driven gear 302 is pushed to rotate until the toothless gear 303 continues to rotate and the tooth groove arranged on the outer side wall of the toothless gear 303 stops contacting the driven gear 302. At this time, the driven gear 302 stops rotating synchronously. Therefore, the driven gear 302 can perform intermittent rotation. A blanking plate 305 is arranged on the inner side wall of the blanking box 301. A connecting rod is welded to the outer side wall of the blanking plate 305. One end of the connecting rod extends to the outside of the blanking box 301 and is threadedly connected to the outer side wall of the driven gear 302. Therefore, when the driven gear 302 rotates, the blanking plate 305 can be driven to rotate synchronously. A feeding groove 306 is formed inside the blanking plate 305. There are four groups of feeding grooves 306, and the four groups of feeding grooves 306 are equidistantly distributed around the outer side wall of the blanking plate 305, and the positions of the four groups of feeding grooves 306 are distributed in a "cross" shape. When the driven gear 302 rotates intermittently, the blanking plate 305 can be driven to rotate synchronously. When a group of feeding grooves 306 rotates to the lower part, the plastic particles in the feeding groove 306 can be put into the interior of the heating box 1, and another group of feeding grooves 306 is located above, and the plastic particles inside the feeding box 201 are put into the interior of this group of feeding grooves 306. Therefore, the blanking plate 305 can perform intermittent blanking work, reducing the occurrence of plastic particle blockage problems.
[0034] Working principle: First, start the first motor 304 through the control panel, and then pour plastic particles into the interior of the feeding box 201. The plastic particles are poured into the interior of a group of feeding grooves 306 through the inclined plate 202;
[0035] Secondly, after the first motor 304 starts, the output end of the first motor 304 drives the toothless gear 303 to rotate. When the tooth groove on the outer wall of the toothless gear 303 contacts the driven gear 302, the toothless gear 303 drives the driven gear 302 to rotate. When the tooth groove on the outer wall of the toothless gear 303 stops contacting the driven gear 302, the driven gear 302 stops rotating. When the driven gear 302 rotates, it synchronously drives the blanking disk 305 to rotate. When the blanking disk 305 rotates, plastic particles are sequentially poured into the interiors of the remaining three feeding slots 306. When a feeding slot 306 moves to the lower side, the plastic particles inside it are poured into the interior of the heating box 1, thereby realizing intermittent blanking work;
[0036] Finally, the second motor 4 and the heating mechanism 6 are turned on through the control panel. The output end of the second motor 4 drives the stirring rod to rotate, and the stirring rod drives the plastic particles to move. The heating mechanism 6 continuously conveys hot air into the interior of the heating box 1 to heat the plastic particles. After the heating work is completed, the plastic particles are taken out from the interior of the heating box 1 through the discharge pipe 5, and the work is finally completed.
[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
