Description
Technical Field
[0001] This utility model relates to the field of plastic processing technology, and in particular to a hot melt device for processing plastic particles. Background Technology
[0002] In the field of plastic particle processing, hot melting is a crucial step, significantly impacting the molding quality and performance of subsequent plastic products. As a material widely used in various industrial and consumer sectors, the diversity and complexity of plastic products necessitate precise and efficient hot melting treatment of plastic particles during processing. From everyday plastic products such as containers and toys to industrial plastic parts and pipes, different applications place stringent requirements on the physical properties, chemical stability, and appearance quality of plastic products.
[0003] Existing hot melt equipment suffers from the following problems during use: 1. Traditional hot melt equipment typically focuses only on the heating and melting process of plastic particles, with weak pretreatment of raw materials. For example, during the feeding process, most devices lack precise premixing and quantitative control of different plastic particles. Some simple hot melt equipment simply adds various plastic particles together into the hot melter, making it difficult to ensure the uniformity of mixing. This can easily lead to unstable quality of the final product, resulting in uneven material distribution and inconsistent performance. 2. Existing technologies often lack efficient and environmentally friendly preheating methods, failing to fully utilize the heat energy generated during the hot melt process, resulting in energy waste. Therefore, a hot melt device for processing plastic particles is needed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hot melt device for processing plastic particles.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hot melt device for processing plastic particles, comprising a hot melter, a water tank placed on the back of the hot melter, a discharge port opened on one side of the top of the hot melter, a mixing box snapped into the middle of the top of the hot melter, the mixing box being tilted to one side, an air inlet support pipe connected to the other side of the top of the hot melter, the bottom end of the air inlet support pipe penetrating the interior of the hot melter, a preheating box installed at the top of the air inlet support pipe, the top end of the air inlet support pipe penetrating the interior of the preheating box, a conduit penetrating the interior of the preheating box, and the bottom end of the conduit penetrating the interior of the mixing box.

The end of the water injection pipe is connected to the water injection box.
[0007] Preferably, a hopper is provided on one side of the mixing box, and the hopper and the discharge port are fitted and aligned.
[0008] Preferably, the middle part of the conduit is located inside the preheating box, a hot drying oven is installed on one side of the bottom of the preheating box, the bottom of the hot drying oven is connected to the air inlet support pipe, one end of the hot drying oven is connected to the air guide pipe, and the air guide pipe passes through the outside of the preheating box.
[0009] Preferably, a drain outlet is provided on the other side of the bottom of the preheating box, and a drain pipe is connected to the bottom end of the drain outlet. The end of the drain pipe is connected to the water injection tank.
[0010] Preferably, the end of the conduit is equipped with a feeding tube end, and measuring chambers are installed on both sides, as well as on the front and back of the feeding tube end. The measuring chambers and the feeding tube end are integrated.
[0011] Preferably, a feed end is installed at the top of the measuring chamber, and a pull plate is slidably connected inside the measuring chamber.

[0012] Beneficial effects
[0013] In this invention, the mixing chamber enables thorough mixing of various plastic particles. Its vibration function plays a crucial role in the mixing process, ensuring uniform distribution of different plastic particles and avoiding material distribution differences caused by uneven mixing. This results in more stable and consistent physical properties of the final plastic product. During the feeding stage, the precise coordination between the measuring chamber and the electronic weighing device enables accurate metering and automatic addition of different plastic particles, strictly controlling the input amount of each raw material and effectively reducing product quality fluctuations caused by raw material ratio deviations. Furthermore, the preheating chamber preheats the plastic particles, ensuring they are close to their melting temperature before entering the hot melt melt. This not only reduces the heating load on the hot melt melt but also allows for more uniform heating of the plastic within the melt melt, further optimizing the quality of the plastic melt. This ensures that the molded plastic product has excellent surface smoothness, internal structural integrity, and stable chemical properties, significantly improving the product yield and meeting the stringent requirements of various industries for high-quality, high-performance plastic products.
[0014] This invention demonstrates outstanding advantages in improving production efficiency and energy conservation and environmental protection. Regarding production efficiency, the automated metering and feeding functions of the measuring chamber significantly shorten raw material preparation time. Compared to traditional manual operation or simple equipment, it can more quickly and accurately complete the proportional addition of various plastic particles, providing an efficient material supply guarantee for subsequent hot-melting and molding processes. The preheating box utilizes the hot air generated by the hot melter to preheat the plastic particles in the conduit, and further enhances the preheating effect by generating high-temperature steam through a water circulation system. This heat energy recycling mechanism significantly reduces the additional energy consumption required for preheating and accelerates the speed at which the plastic particles reach the hot-melting temperature, thereby shortening the overall production cycle. From an energy conservation and environmental protection perspective, the design of the internal water circulation system realizes the recycling of water resources, avoiding waste. Simultaneously, the exhaust pipe on one side of the hot-drying oven can be connected to a waste gas purification device, effectively treating the waste gas generated during production, reducing environmental pollution, and conforming to modern green production concepts. In large-scale plastic particle processing, it can effectively reduce production costs, improve the economic and social benefits of enterprises, and make a positive contribution to environmental protection.

Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:
[0025] Reference Figure 1-5 A hot melt device for processing plastic particles includes a hot melter 1, a water tank 9 placed on the back of the hot melter 1, a discharge port 2 opened on one side of the top of the hot melter 1, a mixing box 3 snapped into the middle of the top of the hot melter 1, the mixing box 3 tilted to one side, an air inlet support pipe 15 connected to the other side of the top of the hot melter 1, the bottom end of the air inlet support pipe 15 penetrating the interior of the hot melter 1, a preheating box 6 installed at the top of the air inlet support pipe 15, the top end of the air inlet support pipe 15 penetrating the interior of the preheating box 6, a conduit 4 penetrating the interior of the preheating box 6, and the bottom end of the conduit 4 penetrating the interior of the mixing box 3.
[0026] This equipment is mainly used for hot melting of plastic particles. During feeding, the plastic particles are fed from the feeding pipe end 7 and the conduit 4 into the mixing box 3. The preheating box 6 preheats the plastic particles in the conduit 4. The mixing box 3 is vibrating and controlled by a vibration motor. The mixing box 3 is used to mix various plastic particles and then feed them into the hot melter 1 from the bottom side of the hopper 8 for heating. The hot melter 1 is existing equipment and will not be described in detail here. The hot air generated in the hot melter 1 enters the hot drying oven 14 in the preheating box 6 through the air inlet support pipe 15. The hot drying oven 14 is made of heat-conducting material and will be quickly heated by the hot air.
[0027] A water injection pump assembly 5 is installed on the top of the preheating box 6. A spray pipe head 11 is connected to the bottom of the water injection pump assembly 5. The spray pipe head 11 is located at the top inside the preheating box 6. A water injection pipe 10 is connected to the back of the water injection pump assembly 5. The end of the water injection pipe 10 is connected to the water injection tank 9. A hopper 8 is provided on one side of the mixing box 3. The hopper 8 and the discharge port 2 are aligned and fitted together. The middle part of the guide pipe 4 is located inside the preheating box 6. A hot drying oven 14 is installed on one side of the bottom inside the preheating box 6. The bottom of the hot drying oven 14 is connected to the air inlet support pipe 15. One end of the hot drying oven 14 is connected to the air guide pipe 13. The air guide pipe 13 passes through the outside of the preheating box 6. A drain outlet 12 is opened on the other side of the bottom inside the preheating box 6. A drain pipe 16 is connected to the bottom of the drain outlet 12. The end of the drain pipe 16 is connected to the water injection tank 9.
[0028] The water pump assembly 5 indirectly draws water from the water tank 9 and sprays it onto the surface of the hot drying oven 14 through the spray nozzle 11. The hot drying oven 14 quickly heats the water droplets and generates high-temperature steam. The high-temperature steam heats the conduit 4 as it rises, thereby preheating the plastic particles inside the conduit. The water droplets falling on the hot drying oven 14 slide towards the drain outlet 12 as the oven body tilts, and are discharged back into the water tank 9 through the drain outlet 12 and the drain pipe 16 to achieve water circulation. The air duct 13 on one side of the hot drying oven 14 is used to discharge internal gas. The duct can be opened when needed. The end of the air duct 13 can be connected to an exhaust gas purification device, so as not to affect the environment. Specific Implementation Example 2:
[0030] Reference Figure 1-5 The end of the conduit 4 is equipped with a feeding pipe end 7. Measuring chambers 17 are installed on both sides, as well as on the front and back of the feeding pipe end 7. The measuring chambers 17 and the feeding pipe end 7 are integrated.
[0031] The top of the measuring chamber 17 is equipped with a feed end 18. The interior of the measuring chamber 17 is slidably connected with a pull plate 19. An electronic weighing device 20 is embedded in the top of the pull plate 19. A telescopic cylinder assembly 23 is installed on one side of the pull plate 19. A cylinder controller 22 is electrically connected to one side of the telescopic cylinder assembly 23. A fixed frame 21 is embedded in one side of the measuring chamber 17. The cylinder controller 22 and the telescopic cylinder assembly 23 are both located on the fixed frame 21.
[0032] As shown in the figure, four sets of measuring components are installed on the outside of the feeding pipe end 7 at the top of the conduit 4. This can be used when multiple different plastic particles need to be mixed and melted. Different plastic particle raw materials are poured into different feeding ends 18, and then the raw materials enter the measuring chamber 17. The raw materials fall onto the electronic weighing device 20. When the weight reaches the required value, a signal is automatically transmitted to the cylinder controller 22 through the built-in transmission chip. The cylinder controller 22 receives the signal through a matching receiving chip. After receiving the signal, the cylinder controller 22 controls the telescopic cylinder assembly 23 to retract, thus... The entire pull plate 19 will be pulled out, and the raw material on the pull plate 19 structure will fall from the bottom into the feeding pipe end 7. It should be noted that the electronic weighing device 20 here is an electronic belt scale, which can ensure accurate measurement even when the material is tilted. The electronic belt scale is mainly composed of a weighing frame, a speed sensor, a high-precision weighing sensor, and an electronic belt scale control and display instrument, etc. It is used for continuous dynamic measurement of solid materials. Alternatively, the measuring chamber 17 can be set in a vertical state, and a pipe can be installed at the bottom of the measuring chamber 17 to connect to the feeding pipe end 7. In this way, even ordinary weighing instruments can be used.
[0033] In summary:
[0034] 1. In this equipment, the water pump assembly 5 indirectly draws water from the water tank 9 and sprays it onto the surface of the hot drying oven 14 through the spray nozzle 11. The hot drying oven 14 quickly heats the water droplets and generates high-temperature steam. The high-temperature steam heats the conduit 4 during its ascent, thereby preheating the plastic particles inside the conduit. The water droplets falling on the hot drying oven 14 slide towards the drain outlet 12 as the oven body tilts, and are discharged back into the water tank 9 through the drain outlet 12 and the drain pipe 16 to achieve water circulation. The air duct 13 on one side of the hot drying oven 14 is used to discharge internal gas. The duct can be opened when needed. The end of the air duct 13 can be connected to an exhaust gas purification device, so as not to affect the environment.
[0035] 2. This device can be used when multiple different plastic particles need to be mixed and melted. Different plastic particle raw materials are poured into the feed end 18 at different positions. The raw materials then enter the measuring chamber 17 and fall onto the electronic weighing device 20. When the weight reaches the required value, a signal is automatically transmitted to the cylinder controller 22 through the built-in transmission chip. The cylinder controller 22 receives the signal through the matching receiving chip. After receiving the signal, the cylinder controller 22 controls the telescopic cylinder assembly 23 to retract, which pulls out the entire pull plate 19. The raw materials on the pull plate 19 structure fall from the bottom into the feeding pipe end 7. It should be noted that the electronic weighing device 20 here is an electronic belt scale, which can ensure accurate measurement even when the material is tilted. The electronic belt scale mainly consists of a weighing frame, a speed sensor, a high-precision weighing sensor, and an electronic belt scale control display instrument. It is used for continuous dynamic measurement of solid materials. Alternatively, the measuring chamber 17 can be set vertically, and a pipe can be installed at the bottom of the measuring chamber 17 to connect to the feeding pipe end 7.
