Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic particle preheating, in particular to a plastic particle preheating device for plastic product manufacturing. BACKGROUND

[0002] The plastic particle preheating device used in plastic product manufacturing is to ensure that the plastic particles reach a proper temperature before entering the processing process such as extrusion or injection molding, to ensure the processing performance of the plastic and the quality of the final product. Preheating can help remove moisture and other volatile substances in the plastic particles, reducing defects in the processing process.

[0003] As disclosed in Chinese patent CN220095162U, a plastic particle preheating device for plastic product manufacturing is provided. The device includes a flat bottom plate on the upper surface to ensure that all plastic particles can be stirred during stirring by the stirring rod, avoiding dead angles. A through opening is provided on the upper surface of the bottom plate, and a baffle is arranged in the through opening. The opening and closing of the baffle are driven by an electric push rod, allowing the plastic particles to be completely discharged and ensuring that all plastic particles can be uniformly preheated. A horizontal rod, a first scraper, a vertical rod, and a second scraper are provided. During the rotation of the stirring rod, the first scraper removes the bottom plate, and the second scraper removes the inner wall of the tank, effectively preventing the adhesion of plastic particles.

[0004] For this structure, although the plastic particles can be stirred, the stirring is relatively single, resulting in uneven preheating of the plastic. Therefore, we propose a plastic particle preheating device for plastic product manufacturing that can uniformly stir and preheat the plastic particles to improve the preheating effect.

[0024] Embodiment 1: the preferred embodiment of the plastic particle preheating device for plastic product manufacturing provided by the utility model is as shown in Figures 1 to 6 A plastic particle preheating device for plastic product manufacturing, comprising a tank body 1;

[0025] The tank body 1 top surface is provided with a feed inlet 2;

[0026] The tank body 1 bottom is provided with a discharge outlet 3;

[0027] The tank body 1 below is provided with a support plate 5;

[0028] The tank body 1 inner wall is fixedly installed with a heating sheet 6;

[0029] And the processing assembly 4 arranged above the support plate 5, the processing assembly 4 includes a mixing assembly 41 arranged above the support plate 5, the mixing assembly 41 includes a mounting plate 411 fixedly installed on the top surface of the tank body 1, the outer wall of the mounting plate 411 is fixedly installed with a motor 412, the output end of the motor 412 is fixedly installed with a rotating rod 413, one end of the rotating rod 413 away from the motor 412 is fixedly installed with a rotating frame 414, one end of the rotating frame 414 away from the rotating rod 413 is fixedly installed with a wedge-shaped rod 415, the outer wall of the wedge-shaped rod 415 is hingedly connected with a stirring rod 416, the outer wall of the stirring rod 416 is slidably provided with a first sleeve ring 417, the outer wall of the first sleeve ring 417 is hingedly connected with a connecting plate 418, the inside of the rotating frame 414 is fixedly installed with a telescopic rod 419, the end of the telescopic rod 419 is fixedly installed with an L-shaped plate 420, one end of the L-shaped plate 420 away from the telescopic rod 419 is hingedly connected with a second sleeve ring 421, and the inside of the tank body 1 is rotatably connected with a scraping frame 422.

[0030] When the plastic particles need to be preheated in the embodiment, they are added into the tank 1 through the feeding port 2, and the heating sheet 6 is started to preheat the plastic particles. In order to make the preheating more uniform, the motor 412 is started at this time, and the output end of the rotating rod 413 fixedly installed is rotated, the rotating rod 413 drives the rotating frame 414 to rotate, the rotating frame 414 drives the wedge-shaped rod 415 to rotate, and the wedge-shaped rod 415 drives the stirring rod 416 hingedly connected to the outer wall thereof to rotate, so that the plastic particles in the tank 1 are stirred and treated, and the preheating is more uniform. When different parts in the tank 1 need to be stirred, the telescopic rod 419 is started at this time, and the L-shaped plate 420 is pushed downward. Since the end of the L-shaped plate 420 is hingedly connected to the outer wall of the second sleeve 421, and the second sleeve 421 is slidingly arranged on the outer wall of the stirring rod 416, the second sleeve 421 pushes the stirring rod 416 under the limitation to make the stirring rod 416 deflect with the hinge of the wedge-shaped rod 415 as the center. Since the first sleeve 417 sleeved on the outer wall of the stirring rod 416 is hingedly connected to the connecting plate 418, the stirring rod 416 drives another stirring rod 416 to deflect through the connecting plate 418, so as to adjust the stirring range of the stirring rod 416, and the plastic particles in different parts of the tank 1 can be stirred. When the plastic particles are attached to the inner wall of the tank 1, the telescopic rod 419 is started at this time, and the same L-shaped plate 420 and the second sleeve 421 pull the stirring rod 416 to be perpendicular to the wedge-shaped rod 415. At this time, the outer wall of the rotating stirring rod 416 is in contact with and extruded by the outer wall of the scraping frame 422, so that the rotating stirring rod 416 can drive the scraping frame 422 to rotate in the tank 1. Since the outer wall of the scraping frame 422 is abutted to the inner wall of the tank 1, the inner wall of the tank 1 can be cleaned under the rotation limitation of the scraping frame 422, so as to avoid the attachment of the plastic particles. The structure can adjust the state of the stirring rod 416 in the tank 1 to adjust the stirring range and make the stirring diversified. The stirring rod 416 perpendicular to the wedge-shaped rod 415 can drive the scraping frame 422 to rotate to clean the inner wall of the tank 1, so as to improve the preheating effect of the plastic particles (the tank 1, the feeding port 2, the discharging port 3, the processing assembly 4, and the heating sheet 6 are the existing disclosed technologies in the comparative file, so the structure thereof is not fully described in the case).

[0031] Further, the outer wall of the scraping frame 422 is rotationally connected to the inner wall of the tank 1, and the end of the wedge-shaped rod 415 away from the rotating frame 414 is obliquely arranged. When the wedge-shaped rod 415 drives the stirring rod 416 perpendicular thereto to rotate, the stirring rod 416 can drive the scraping frame 422 to rotate, so that the scraping frame 422 cleans the inner wall of the tank 1.

[0032] Further, the L-shaped plate 420 is hingedly connected with the second ring 421, the stirring rod 416 is hingedly connected with the wedge-shaped rod 415, the end of the connecting plate 418 is hingedly connected with the first ring 417, the second ring 421 and the first ring 417 are slidingly arranged on the outer wall of the stirring rod 416, and under the limitation, the downward movement of the L-shaped plate 420 pushes the stirring rod 416 through the second ring 421 to change the stirring amplitude of the stirring rod 416.

[0034] In this embodiment, when the wedge-shaped rod 415 rotates, the end inclined surface thereof is in contact with and extrudes the inclined surface of the wedge-shaped column 431, so that the wedge-shaped rod 415 drives the tank body 1 to move upward, the fixed block 432 fixedly installed on the outer wall of the tank body 1 slides on the outer wall of the sliding rod 433 fixedly installed on the top surface of the support plate 5, when the wedge-shaped rod 415 rotates one circle and resets, the wedge-shaped rod 415 no longer extrudes the wedge-shaped column 431, the tank body 1 moves downward and extrudes the spring 434, so that the tank body 1 reciprocates to generate an up-and-down vibration effect, thereby improving the mixing effect of the plastic particles in the tank body 1, and when the plastic particles in the tank body 1 are discharged, the auxiliary discharge can be performed.

[0035] Further, the end of the wedge-shaped column 431 is provided in an inclined surface, and the wedge-shaped column 431 is in contact with the inclined surface of the wedge-shaped rod 415, under the limitation, the rotating wedge-shaped rod 415 can extrude the wedge-shaped column 431, so that the tank body 1 moves up and down as a whole, thereby improving the stirring effect.
