Description

Technical Field

[0001] The present invention belongs to the technical field of recycled plastics, and in particular relates to a plastic hot-melt device for curing recycled plastics. Background Art

[0002] Recycled plastics are the reuse of plastics. After being crushed by mechanical blades, the plastics are reused. Recycled plastics refer to plastic raw materials obtained after processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, and modification. It is the reuse of plastics. Recycled plastics and granulated plastics have broad prospects, turning waste into treasure, and the products (plastic granules) are widely sold, and there is a large demand for plastic companies.

[0003] In a Chinese patent with patent number CN201710895125.9, a plastic hot melt device for plastic curing is disclosed. The device heats the raw materials through a hot melt kettle to achieve rapid melting of the curing plastic. However, there are still many defects in actual use. For example, the recycled plastic is easy to adhere to the inner wall of the cavity during the hot melt process, which will not only become thicker and more difficult to remove, but also affect the discharge of the raw materials. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a plastic hot melt device for curing recycled plastics, which can scrape off the plastic adhered to the inner wall of the hot melt box cavity when the recycled plastic adheres to the inner wall of the hot melt box cavity during the hot melt process.

[0005] The purpose of this disclosure can be achieved through the following technical solutions:

[0006] A plastic hot-melt device for curing recycled plastics, comprising:

[0007] A hot melt box, wherein the upper end and the lower end of the hot melt box are respectively provided with a first connecting rod and a second connecting rod, the two ends of the first connecting rod are rotatably connected to a rotating shaft, the other end of the rotating shaft is rotatably connected to the end corresponding to the second connecting rod, the peripheral side of the rotating shaft is fixedly connected to at least one first scraper along the length direction of the rotating shaft, and the lower end of the second connecting rod is fixedly connected to the second scraper;

[0008] The gear ring is fixedly connected to the inner upper end of the hot melt box, the inner side of the gear ring is provided with teeth, the inner side of the gear ring is meshed with two gears, and each gear is fixedly connected to the corresponding rotating shaft.

[0009] The above technical solution, its principle and technical effect:

[0010] When the recycled plastic adheres to the inner wall of the hot melt box cavity during the hot melting process, the first connecting rod is driven to rotate, and the first connecting rod drives the two rotating shafts to rotate around the axis of the hot melt box, and the second connecting rod follows the rotation. At this time, the first scraper scrapes the side wall of the hot melt box, and the second scraper scrapes the bottom of the hot melt box; among them, when the two rotating shafts rotate around the axis of the hot melt box, due to the meshing of the gears and the gear ring, the gears rotate on their own, which further causes the rotating shaft to rotate on its own, thereby better scraping the side walls of the hot melt box.

[0011] In a preferred example, the utility model can be further configured as follows: a feeding port is provided on the upper end cover of the hot melt box, and a feeding hopper is fixedly connected to the feeding port.

[0012] In a preferred example, the utility model can be further configured as follows: a motor is fixedly connected to the upper end cover of the hot melt box, and the output end of the motor passes through the upper end cover of the hot melt box and is fixedly connected to the middle part of the first connecting rod.

[0018] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0019] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0020] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0021] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0022] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0023] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0024] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0025] Beneficial effects of the present disclosure:

[0026] When the recycled plastic adheres to the inner wall of the hot melt box cavity during the hot melting process, the plastic adhered to the inner wall of the hot melt box cavity can be scraped off. BRIEF DESCRIPTION OF THE DRAWINGS
