Technical Field
[0001] This utility model relates to the field of hot melt equipment technology, and in particular to a hot melt equipment for mixing plastic raw materials. Background Technology
[0002] Plastic is a malleable material mainly composed of high molecular polymers, obtained through synthesis or natural means. It has the characteristics of being lightweight, low-cost, easy to process, corrosion-resistant, and highly insulating. It is widely used in various fields such as packaging, construction, electronics, transportation, and medical. Plastic raw materials are the basic materials for manufacturing various plastic products. They are mainly composed of synthetic resins and various additives. Through specific processes, they are processed and shaped. Plastic products have become indispensable items in people's lives. In order to adapt to different scenarios, it is necessary to mix and melt various plastic particles during the processing of plastic products. After melting, they are shaped through molds. This process requires the use of plastic mixing and hot melting equipment.
[0003] In existing technologies, conventional plastic raw material mixing and hot-melting devices typically heat and stir simultaneously. However, the stirring rod usually rotates in one direction, making it difficult for plastic particles to achieve comprehensive and thorough mixing during the stirring process. This results in some particles not being able to make uniform contact with other particles, thus affecting the quality stability of the finished product. Moreover, as the heating process progresses, the plastic particles gradually melt, and their viscosity increases significantly. In this state, the melted plastic particles are very easy to adhere to the inner wall of the machine, which is not only difficult to clean but may also accumulate over time, further affecting the heating efficiency and stirring effect of the device, and may even cause irreversible damage to the quality of the finished product. Therefore, it is necessary to improve the plastic raw material mixing and hot-melting device to solve the above problems. Utility Model Content

The inner side of the scraper 210 is fixedly connected to a second stirring rod 213 for stirring and mixing the raw materials inside the outer shell 1. By synchronously driving the long rod 25 and the rotating sleeve 28 to rotate in opposite directions, the rotating sleeve 28 drives the scraper 210 to scrape off the residue remaining on the inner wall of the outer shell 1. Moreover, the first stirring rod 26 and the second stirring rod 213 mix synchronously in opposite directions. The staggered distribution of the two improves the stirring efficiency, enhances the mixing and melting effect inside the outer shell 1, and improves the practicality of the device. The installation components facilitate the installation and removal of the top cover 5, improve the mixing and melting effect inside the outer shell 1, and improve the cleaning effect of the inner wall of the outer shell 1.
[0023] Please see Figure 2 - Figure 4In this embodiment, the fixing frame 29 has a corresponding groove at the corresponding position of the scraper 210. The scraper 210 is set in the groove of the fixing frame 29, which facilitates the installation and removal of the scraper 210 and the fixing frame 29, thereby improving the individual cleaning effect of the scraper 210 and the cleaning effect on the inner wall of the outer casing 1.

By synchronously driving the long rod 25 and the rotating sleeve 28 to rotate in opposite directions, the rotating sleeve 28 drives the scraper 210 to scrape off the residue remaining on the inner wall of the outer shell 1. Moreover, the first stirring rod 26 and the second stirring rod 213 are synchronously mixed in opposite directions. The staggered distribution of the two improves the mixing efficiency and the mixing and melting effect inside the outer shell 1, thus improving the practicality of the device. The fixing frame 29 and the scraper 210 are both provided with corresponding through holes at the positions of the bolts 211. The bolts 211 are set inside the through holes of the fixing frame 29 and the scraper 210, which facilitates the installation of the scraper 210, improves the installation stability of the scraper 210, and improves the cleaning effect of the scraper 210 on the inner wall of the outer shell 1.
[0024] Please see Figure 1 , Figure 5In this embodiment, the mounting assembly includes a first fixing plate 31, which is fixedly connected to the top cover 5. A second fixing plate 32 is fixedly connected to the outer shell 1. A plug rod 33 is fixedly connected to the top of the second fixing plate 32 and is disposed inside the first fixing plate 31. A handle 34 is fixedly connected to the top of the top cover 5. A plug frame 35 is fixedly connected to the bottom of the top cover 5 and is disposed inside the outer shell 1. A sealing ring 36 for sealing the outer shell 1 and the top cover 5 is fixedly connected to the bottom of the top cover 5. The plug frame 35 is disposed inside the sealing ring 36. A fixing frame 37 is fixedly connected to the outer shell 1. A locking block 38 is slidably connected inside the fixing frame 37, penetrating the outer shell 1 and engaging inside the plug frame 35. An optical axis 39 is fixedly connected to the outside of the locking block 38 and is slidably connected to the fixing frame 37. Inside, a lever 311 is fixedly connected to the optical axis 39, and a spring 310 is fixedly connected between the locking block 38 and the fixing frame 37. The mounting assembly aligns the insert frame 35 into the groove of the outer shell 1 and aligns the first fixing plate 31 into the insert rod 33 to install the top cover 5, making it easy to install and remove the top cover 5, improving the mixing and melting effect inside the outer shell 1, and improving the cleaning effect on the inner wall of the outer shell 1. The outer shell 1 has a matching groove at the corresponding position of the insert frame 35, and the insert frame 35 is set in the groove of the outer shell 1 to install the top cover 5 on the top of the outer shell 1, thus improving the ease of installation of the top cover 5. The insert frame 35 has a matching groove at the corresponding position of the locking block 38, and the locking block 38 is engaged in the groove of the insert frame 35, so that the top cover 5 can be fixed through the groove, thus improving the cleaning effect of the scraper 210.
[0025] During operation, the stand 4 supports the outer shell 1. The required raw materials are poured into the interior of the outer shell 1 through the feed inlet 6. The heating wire 214 is activated to heat the interior of the outer shell 1. At this time, the motor 21 is started, driving the first bevel gear 22 to rotate. The second bevel gear 24 and the third bevel gear 27 mesh with the first bevel gear 22, synchronously driving the long rod 25 and the rotating sleeve 28 to rotate in opposite directions. This drives the first stirring rod 26 to rotate, mixing the plastic raw materials inside the outer shell 1. The rotating sleeve 28 not only drives the scraper 210 to scrape away residues on the inner wall of the outer shell 1, but also, through the synchronous reverse mixing of the first stirring rod 26 and the second stirring rod 213, improves the mixing efficiency and enhances the hot-melting effect inside the outer shell 1. When the scraper 210 needs cleaning, the pusher block 311 is pulled outwards, causing the locking block 38 to move away from the insert frame 35, compressing the spring 310 and releasing it. In addition to securing the top cover 5, the handle 34 is used to pull the top cover 5 out of the housing 1, separating the motor 21 from the housing 1. Then, by removing the nut 212 and bolt 211, the scraper 210 and the fixing bracket 29 can be disassembled, facilitating cleaning of the components on the top cover 5 and improving cleaning efficiency. After cleaning, the scraper 210 is installed on the fixing bracket 29 using bolts 211 and nuts 212. Finally, the insertion frame 35 is aligned with the corresponding groove in the housing 1, allowing the motor 21 to... A fixed plate 31 is inserted into the aligned insertion rod 33. When the insertion frame 35 contacts the arc end of the locking block 38, the locking block 38 moves outward, compressing the spring 310. When the insertion frame 35 is inserted into the deepest part of the outer shell 1, the groove of the insertion frame 35 corresponding to the locking block 38 is in the corresponding position of the locking block 38. At this time, the spring 310, through its own elasticity, causes the locking block 38 to engage in the groove of the insertion frame 35, thus fixing the top cover 5. The sealing ring 36 seals the top cover 5 and the outer shell 1.
[0026] Through the above steps, the long rod 25 and the rotating sleeve 28 are driven to rotate in opposite directions, so that the rotating sleeve 28 drives the scraper 210 to scrape off the residue remaining on the inner wall of the outer shell 1. Moreover, the first stirring rod 26 and the second stirring rod 213 are mixed in opposite directions in a synchronous manner. The staggered distribution of the two improves the stirring efficiency and enhances the mixing and melting effect inside the outer shell 1. This solves the problem that the stirring rod usually rotates in one direction, making it difficult for plastic particles to be mixed in all directions and fully during the stirring process, and that plastic particles are very easy to adhere to the inner wall of the machine.
