Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic melting, and in particular to a plastic heating and stirring device. Background Technology
[0002] Plastic heating and stirring devices play a vital role in the plastics processing industry. In the production process of plastic products, whether it is injection molding, extrusion molding or other molding processes, it is necessary to heat and stir the plastic raw materials. Heating turns the plastic from a solid state to a molten state so that subsequent processing operations can proceed smoothly. Stirring ensures that the plastic is heated evenly during the heating process and that the raw materials are fully mixed, thereby improving the quality stability and performance consistency of plastic products.
[0003] In related technologies, common plastic heating and stirring devices mainly use the following methods to process plastics. For heating, heating elements, such as heating jackets or heating wires, are usually installed inside the stirring container to transfer heat to the plastic inside the container through heat conduction. Stirring is mostly achieved by a stirring paddle installed inside the container. The stirring paddle is generally driven by a motor and rotates and stirs around the container, causing the plastic particles to move within the container and achieve the mixing and heating process.
[0004] While the above methods can achieve heating and stirring of plastics, when the plastic particles are large, their large size and weight limit the range and frequency of movement within the container by relying solely on traditional circumferential stirring methods. This results in low heat transfer efficiency and requires a long time to completely melt, which not only reduces production efficiency but also increases energy consumption. Furthermore, since most existing technologies focus on circumferential stirring, plastic particles are prone to sedimentation at the bottom of the container due to gravity during the stirring process, leading to uneven mixing of the plastic. This, in turn, results in defects in the physical properties and appearance of the produced plastic products, such as air bubbles, uneven density, and rough surfaces. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The plastic heating and stirring device of this utility model embodiment will now be described with reference to the accompanying drawings.
[0024] The plastic heating and stirring device provided by this utility model is mainly used in the production and processing of plastic products. It is used to melt and mix plastic raw materials, which can effectively shorten the time for solid plastic to transform into molten state, thereby effectively improving the production efficiency of plastic and reducing energy consumption.

[0027] It should be noted that the mixing tank 1 described in this embodiment is also equipped with a feed hopper with a valve (not specifically marked in the figure) and a discharge pipe (not specifically marked in the figure).

[0028] In one embodiment of the present invention, the lifting mechanism 3 may include a hydraulic cylinder 301 and a rotating plate 302.
[0029] The hydraulic cylinder 301 is fixedly installed at the bottom of the mixing tank 1, and the movable end of the hydraulic cylinder 301 extends into the mixing tank 1. The rotating plate 302 is fixedly connected to one end of the hydraulic cylinder 301 located inside the mixing tank 1.
[0030] In one embodiment of the present invention, the stirring mechanism 2 may include a rotating rod 201 and a plurality of stirring blades 202.
[0031] The top end of the rotating rod 201 is rotatably connected to the rotating plate 302, and multiple stirring blades 202 are respectively sleeved on the rotating rod 201.
[0032] In one embodiment of the present invention, the crushing mechanism 5 may include a rotating shaft 501 and a crushing blade 502.
[0033] The rotating shaft 501 is rotatably disposed at the bottom of the inner wall of the mixing tank 1, and the crushing blade 502 is sleeved on the rotating shaft 501 and is located inside the mixing tank 1.
[0034] In one embodiment of the present invention, the drive mechanism 6 may include a device box 601, a motor 602, a drive rod 603, a linkage rod 604, a cross-shaped insert rod 605, multiple sprockets 606, a chain 607, a drive gear 608, and a driven gear 609.
[0035] The device box 601 is fixedly installed at the bottom of the mixing tank 1. The bottom ends of multiple rotating shafts 501 are rotatably connected to the bottom of the inner wall of the device box 601. The bottom end of the linkage rod 604 is rotatably installed inside the device box 601. The top end of the linkage rod 604 extends into the mixing tank 1 and is coaxially and fixedly connected to the cross-shaped insert rod 605. The bottom end of the rotating rod 201 has a slot adapted to the cross-shaped insert rod 605. The cross-shaped insert rod 605 extends into the slot and is slidably connected to the rotating rod 201. Multiple sprockets 606 are respectively sleeved on multiple rotating shafts 501 and drive rods 603. A chain 607 is driven on multiple sprockets 606. The motor 602 is installed at the bottom of the device box 601. The output shaft of the motor 602 is coaxially and fixedly connected to the drive rod 603 through a coupling. The drive gear 608 and the driven gear 609 are respectively sleeved on the drive rod 603 and the linkage rod 604, and the drive gear 608 is meshed with the driven gear.
[0036] In one embodiment of the present invention, the heating mechanism 4 may include a housing 401 and a plurality of heating tubes 402.
[0037] The shell 401 is fixedly installed on the inner wall of the mixing tank 1, and multiple heating tubes 402 are respectively installed inside the shell 401.
[0038] Specifically, when heating and stirring solid plastics, the relevant personnel first open the valve of the feed hopper and put the solid plastic raw material into the mixing tank 1. Then, the heating mechanism 4 is started, and the plastic raw material in the mixing tank 1 is heated by the electric heating tube 402. At the same time, the motor 602 is started, and the motor 602 drives the drive rod 603 to rotate. The drive rod 603 drives multiple rotating shafts 501 to rotate through the transmission of the sprocket 606 and the chain 607, so that the crushing blade 502 crushes the plastic raw material. On the other hand, the drive rod 603 drives the drive gear 608 to rotate. The drive gear 608 meshes with the driven gear 609 to rotate the linkage rod 604, which in turn drives the cross-shaped insert rod 605 to rotate. The cross-shaped insert rod 605 drives the rotating rod 201 to rotate. The rotating rod 201 drives the stirring blade 202 to stir the plastic raw material. The stirring and crushing are carried out simultaneously, so that the solid plastic raw material is crushed by the crushing blade 502 and turned into smaller plastic particles. This promotes uniform heating of the plastic raw material and accelerates melting, thereby effectively improving the production efficiency of plastics and reducing energy consumption.
[0039] In addition, the relevant personnel also used the hydraulic cylinder 301 to drive the rotating rod 201 to drive multiple stirring blades 202 to reciprocate up and down. The stirring action of the stirring blades 202 caused the plastic raw materials to continuously tumble and flow in the mixing box 1, which not only promoted the mixing of the plastic raw materials in the horizontal direction (circumferential direction), but also, due to the difference in the vertical position of the stirring blades 202 and the adjustable height of the hydraulic cylinder 301, ensured that the plastic raw materials were fully mixed in the vertical direction, effectively avoiding the phenomenon of plastic sedimentation and ensuring the uniformity of the overall plastic mixing.
[0040] Once the plastic raw materials have completely melted and are evenly mixed, open the valve of the discharge pipe to discharge the molten plastic from the mixing tank 1 for subsequent plastic product molding and other processing steps.
[0041] As one possible scenario, the drive gear 608 and driven gear 609 described in this embodiment may employ commercially available speed-reducing gear transmission mechanisms to drive the crushing blade 502 and the rotating rod 201 to rotate at different speeds.
[0042] In summary, the plastic heating and stirring device of this utility model can effectively shorten the time for solid plastic to transform into molten state, thereby effectively improving the production efficiency of plastic and reducing energy consumption. In addition, it can also effectively prevent plastic sedimentation, thereby effectively improving the uniformity of the overall plastic mixing.
