Description

Technical Field

[0001] This utility model relates to the field of plastic granule thermal melting technology, specifically a modified plastic granule thermal melting device. Background Technology

[0002] Modified plastic granules refer to plastic products that have been modified by filling, blending, and reinforcing methods on the basis of general-purpose plastics and engineering plastics, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness. Modified plastic parts can not only achieve some of the strength properties of steel, but also have a series of advantages such as light weight, rich colors, and easy molding. Therefore, the trend of "replacing steel with plastics" has emerged in many industries.

[0003] Utility model patent CN218659991U discloses a modified plastic granule melting device, which solves the problem of uneven heating in existing melting devices, where modified plastic granules near the heating plate melt first, while those in the middle melt incompletely or very slowly, resulting in low melting efficiency in actual production. The new device uses a process where plastic granules fall from the discharge port into the guide hopper, and then from the outlet onto a second electric heating plate, where the second electric heating plate heats and melts the falling plastic granules. The molten plastic granules flow downwards into the heating cylinder, where they are reheated and maintained at a temperature by the first electric heating plate. Simultaneously, the intermittent feeding component allows the falling granules to contact the second electric heating plate, resulting in more even heating and improved melting efficiency. However, in actual use, the edge of the second heating plate is angled, leading to very short contact time between the granules and the plate. This results in poor heating of the granules by the second heating plate, indirectly affecting the overall heating effect of the device. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a modified plastic granule thermal melting device with the advantage of good heating and melting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modified plastic granule thermal melting device, comprising a base plate, a heating cylinder fixedly connected to the top of the base plate via a support column, a feed pipe connected to the top of the heating cylinder, a quantitative preheating component provided at the top of the heating cylinder, a rotating shaft movably connected inside the heating cylinder, a first spiral conveying blade and a second spiral conveying blade fixedly connected to the surface of the rotating shaft respectively, a first gear fixedly connected to the left side of the rotating shaft, a first motor fixedly connected to the left side of the heating cylinder via a bracket, the output end of the first motor fixedly connected to the first gear, a stirring component provided inside the heating cylinder, an extrusion pipe attached to the right side of the heating cylinder, and a first heating plate fixedly connected to the surface of the heating cylinder.

[0008] As a preferred embodiment of this invention, the top of the base plate is inclined.

[0009] As a preferred embodiment of this utility model, cylinders are fixedly connected to all four sides of the bottom of the base plate, and threaded rods are threadedly connected to the inside of the cylinders, with a support pad fixedly connected to the bottom of the threaded rods.

[0010] As a preferred embodiment of this invention, both the surface of the heating cylinder and the surface of the extrusion tube are fitted with flanges, and the two flanges are fixedly connected by bolts and nuts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model involves the operator pouring plastic granules into the feed hopper, adjusting the metering wheel to rotate clockwise, and then activating the second heating plate. As the metering wheel rotates, the plastic granules fall at a uniform speed. When the granules adhere to the inner wall of the metering cylinder, they are preheated by the second heating plate. The preheated granules fall into the heating cylinder, where the first heating plate is activated to further heat the granules. The stirring assembly ensures uniform heating. The operator then activates the first motor, which in turn rotates the first gear, which in turn rotates the shaft, which in turn rotates the first and second spiral conveyor blades. This conveys the heated and melted material to the right and then discharges it through the extrusion pipe. This device has the advantage of excellent heating and melting effect.

[0013] 2. With the addition of a quantitative preheating component, the operator can pour plastic granules into the feed hopper, then start the second motor to rotate clockwise, which in turn drives the quantitative wheel to rotate clockwise. Then, the second heating plate is activated. As the quantitative wheel rotates, it causes the plastic granules to fall at a uniform speed. When the plastic granules come into contact with the inner wall of the quantitative cylinder, they are preheated by the second heating plate. The plastic granules can be effectively preheated inside the quantitative cylinder, thereby indirectly improving the heating and melting effect of the device. Attached Figure Description

A heating cylinder 2 is fixedly connected to the top of the base plate 1 via a support column. A feed pipe 3 is connected to the top of the heating cylinder 2.

A rotating shaft 5 is movably connected inside the heating cylinder 2. A first spiral conveying blade 6 and a second spiral conveying blade 7 are fixedly connected to the surface of the rotating shaft 5, respectively. The diameter of the first spiral conveying blade 6 is smaller than the diameter of the second spiral conveying blade 7. A first gear 9 is fixedly connected to the left side of the rotating shaft 5.

[0022] As a technical optimization of this utility model, by setting up the quantitative preheating component 4, the operator can pour plastic granules into the feed hopper 14, then start the second motor to rotate clockwise, which in turn drives the quantitative wheel 13 to rotate clockwise, and then start the second heating plate 16. When the quantitative wheel 13 rotates, it drives the plastic granules to fall at a uniform speed. When the plastic granules are in contact with the inner wall of the quantitative cylinder 12, they are preheated by the second heating plate 16. The plastic granules can be effectively preheated in the quantitative cylinder 12, thereby indirectly improving the heating and melting effect of the device.

[0023] refer to Figure 1 and Figure 2The stirring assembly 11 includes three stirring rods 17 movably connected inside the heating cylinder 2. The stirring rods 17 are evenly distributed in a ring inside the heating cylinder 2. The left end of the stirring rod 17 extends to the left side of the heating cylinder 2 and is fixedly connected to a second gear 18. The first gear 9 meshes with the second gear 18.

[0024] As a technical optimization of this utility model, by setting the stirring assembly 11, the first motor 10 rotates to drive the first gear 9 to rotate, which in turn drives the three second gears 18 to rotate, which in turn drives the stirring rod 17 to rotate. The stirring rod 17 can stir the plastic granules, so that the plastic granules can be uniformly heated and melted in the heating cylinder 2, thereby improving the heating and melting effect.

[0025] refer to Figure 1 The top of the base plate 1 is inclined.

[0026] As a technical optimization of this utility model, by setting the top of the base plate 1 at an incline, the opening on the right side of the heating cylinder 2 can be tilted slightly downward, which facilitates the discharge of materials inside the heating cylinder 2.

[0027] refer to Figure 1 and Figure 4 A cylinder 20 is fixedly connected to all four sides of the bottom of the base plate 1. A threaded rod 21 is threadedly connected inside the cylinder 20. A support pad 22 is fixedly connected to the bottom of the threaded rod 21.

[0028] As a technical optimization of this utility model, by setting up the cylinder 20, the threaded rod 21 and the support pad 22, the operator can rotate the threaded rod 21, thereby driving the support pad 22 to move up or down, thereby adjusting the height or level of the base plate 1.

[0029] refer to Figure 1 and Figure 2 Flanges 19 are fitted on the surface of the heating cylinder 2 and the surface of the extrusion tube 8, and the two flanges 19 fit together and are fixedly connected by bolts and nuts.

[0030] As a technical optimization of this utility model, by setting flange 19, the operator can connect heating cylinder 2 to extrusion tube 8 with bolts and nuts.

[0031] The working principle and usage process of this utility model are as follows: During use, the operator pours plastic granules into the feed hopper 14, then adjusts the metering wheel 13 to rotate clockwise, and then activates the second heating plate 16. As the metering wheel 13 rotates, it causes the plastic granules to fall at a uniform speed. When the plastic granules adhere to the inner wall of the metering cylinder 12, they are preheated by the second heating plate 16. The preheated plastic granules fall into the heating cylinder 2. Then, the first heating plate 15 is activated. There are three first heating plates 15, distributed on the front, back, and bottom of the heating cylinder 2, respectively, to uniformly heat the plastic granules inside the heating cylinder 2. The stirring assembly 11 also ensures uniform heating of the plastic granules. The operator starts the first motor 10 to rotate, driving the first gear 9 to rotate, which in turn drives the rotating shaft 5 to rotate, which in turn drives the first spiral conveying blade 6 and the second spiral conveying blade 7 to rotate, thus conveying the heated and melted material to the right and then discharging it through the extrusion pipe 8.
