Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically to a plastic production hot melting machine. Background Technology

[0002] In the current plastics production industry, hot melt machines, as core melting equipment, still have many unresolved technical pain points.

[0003] First, plastic raw materials are often composed of a mixture of multiple components with different melting points. Traditional hot melt machines use a single heating mode, which can easily lead to stratification during the melting process. This means that low-melting-point components melt excessively while high-melting-point components do not melt sufficiently, ultimately affecting the uniformity of the melt and causing unstable mechanical properties of subsequent plastic products. Second, the hot melting of plastics produces gas containing trace amounts of melt droplets. Existing exhaust structures can only filter large particles and cannot intercept tiny droplets. These droplets, once discharged with the gas, easily adhere to the equipment surface or diffuse into the air, not only contaminating the equipment but also potentially affecting the health of operators. Furthermore, after preheating, some particles of the raw material are prone to agglomerate due to heat. Agglomerated raw material requires a longer melting time when entering the hot melt chamber, extending the overall processing cycle and potentially clogging the feeding channel, causing equipment downtime. Utility Model Content

[0004] In view of the problems existing in the current plastic production process, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a plastic production hot melt machine that solves the problem that traditional hot melt machines use a single heating mode, which easily leads to stratification during the melting process of raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A plastic production hot melting machine includes a machine body. A feed inlet is fixedly located at the top of the machine body. A heating wire is fixedly located inside the feed inlet. A first control block is fixedly located on the outer wall of the feed inlet. A motor is fixedly located at the top of the machine body. A stirring rod is fixedly located at the output end of the motor. A cutting blade is fixedly located on the wall of the stirring rod, and an L-shaped scraper and an oblique scraper are fixedly located on the wall of the rod. Multiple heating rings are fixedly located on the outer wall of the multiple heating rings. A heat insulation ring is fixedly located on the outer wall of the heat insulation ring. A second control block is fixedly located on the outer wall of each heat insulation ring. A discharge port is fixedly located at the bottom of the machine body. A flow rate sensor is fixedly located on the outer wall of the machine body.

[0007] Preferably, an exhaust pipe is fixedly provided on the top of the machine body, and a filter box and a cooler are fixedly provided on the wall of the exhaust pipe.

[0008] Preferably, a uniform cooling ring and a temperature sensor are fixedly provided on the outer wall of the discharge port.

[0009] Preferably, a control panel is fixedly provided on the outer wall of the machine body, a display screen is fixedly provided on the top of the control panel, and a wireless communication module is fixedly provided on one side of the display screen.

[0010] Furthermore, a water storage box is threaded onto one side of the cooler.

[0011] Preferably, a shock-absorbing seat is fixedly provided at the bottom of the machine body.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: In this invention, the heating wire inside the feed inlet, in conjunction with the first control block, can preheat the raw material. At the same time, the cutting edge of the stirring rod wall can quickly break up the raw material clumps that form after preheating, preventing clumps from clogging the feed channel or prolonging the melting cycle. When the stirring rod rotates, the L-shaped scraper and the inclined scraper can not only scrape off the residual material attached to the inner wall of the machine to prevent the accumulation of residual material from affecting the melt quality, but also drive the raw material to tumble fully, avoiding the problem of raw material melting and stratification caused by single heating. This ensures that both low-melting-point and high-melting-point components are fully melted, significantly improving the uniformity of the melt, and thus ensuring the stability of the mechanical properties of subsequent plastic products.

[0013] In this invention, the heat insulation ring on the outside of the machine body can effectively block the heat generated by the heating ring from radiating outward, avoiding energy waste caused by heat loss. The heat preservation ring can maintain the stable melting temperature inside the machine body, reduce the energy consumption caused by frequent start-stop of the heating ring, and at the same time reduce the impact of heat radiation on the workshop ambient temperature, reduce the operating load of the workshop cooling equipment, and achieve the dual effect of energy saving and improving the production environment.

[0014] In this invention, the flow rate sensor on the outside of the machine body can monitor the flow state of the melt inside the machine body in real time, and the temperature sensor at the discharge port can detect the temperature of the discharged melt in real time. The data from both can be fed back to the control panel, which makes it easy for operators to detect problems such as slow melt flow and abnormal temperature in a timely manner, avoiding the generation of batches of defective products due to failure to handle faults in time, and effectively improving production stability and product qualification rate.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a hot melting machine for plastic production.

[0020] This utility model provides, for example Figure 1-3The plastic production hot melting machine shown includes a machine body 1. A feed inlet 2 is fixedly located at the top of the machine body 1. A heating wire 3 is fixedly located inside the feed inlet 2. A first control block 4 is fixedly located on the outer wall of the feed inlet 2. A motor 5 is fixedly located at the top of the machine body 1. A stirring rod 6 is fixedly located at the output end of the motor 5. A cutting blade 7 is fixedly located on the wall of the stirring rod 6, and an L-shaped scraper 8 and an oblique scraper 9 are fixedly located on the wall of the rod. Multiple heating rings 10 are fixedly located on the outer wall of the multiple heating rings 10. A heat insulation ring 11 is fixedly located on the outer wall of the heat insulation ring 11. A heat preservation ring 12 is fixedly located on the outer wall of each heat preservation ring 12. A second control block 13 is fixedly located on the outer wall of each heat preservation ring 12. A discharge port 14 is fixedly located at the bottom of the machine body 1. A flow rate sensor 15 is fixedly located on the outer wall of the machine body 1. The operator feeds plastic raw materials from the machine... The material is fed into the feed inlet 2 at the top of the machine body 1. The preheating temperature of the feed inlet 2 and the heating temperature of the machine body 1 are set via the control panel 21. The parameter commands are transmitted to the first control block 4 and the second control block 13. The first control block 4 activates the heating wire 3 inside the feed inlet 2 to preheat the raw material and soften it initially. At the same time, the motor 5 at the top of the machine body 1 starts, driving the stirring rod 6 at the output end to rotate. The cutting blade 7 on the wall of the stirring rod 6 rotates at high speed with the stirring rod 6, quickly breaking up the raw material clumps formed by heat adhesion during the preheating process. This prevents the clumps from blocking the feed channel or prolonging the melting cycle after entering the machine body 1, ensuring that the raw material enters the machine body 1 smoothly. After the preheated raw material enters the machine body 1, the second control block 13 activates multiple heating rings on the outer wall of the machine body 1. 10. The heating ring 10 generates heat to melt the raw materials inside the machine body 1. The heat insulation ring 11 on the outside of the machine body 1 prevents the heat from the heating ring 10 from radiating outward, reducing heat loss. The heat preservation ring 12 maintains a stable melting temperature inside the machine body 1, preventing temperature fluctuations from affecting the melting effect. The stirring rod 6 rotates continuously, and the L-shaped scraper 8 and the inclined scraper 9 on its rod wall move synchronously. The L-shaped scraper 8 rotates against the inner wall of the machine body 1, scraping off the molten residue adhering to the inner wall of the machine body 1, preventing the residue from accumulating and deteriorating, thus affecting the melt quality. The inclined scraper 9 drives the raw materials inside the machine body 1 to tumble up and down, ensuring that the raw materials are in full contact with the heat transferred by the heating ring 10. Combined with the zoned heating effect of multiple heating rings 10, precise temperature control is achieved for plastic components with different melting points, preventing the raw materials from melting and separating, and ensuring the desired melting effect. All components are fully melted to form a homogeneous melt. Gas containing impurities and melt droplets generated during the melting process is discharged through the exhaust pipe 16 at the top of the machine body 1. The gas first passes through a filter box 17 on the wall of the exhaust pipe 16, which intercepts large particulate impurities. The gas then enters a cooler 18, which cools the gas, causing trace melt droplets to condense into a liquid state. The condensed melt flows along the inner wall of the cooler 18 into a water storage box 24 connected by a thread on one side, achieving melt recycling, reducing raw material waste, and preventing droplet contamination of equipment or harm to operator health. Clean gas is discharged from the end of the exhaust pipe 16. A flow rate sensor 15 on the outer wall of the machine body 1 monitors the flow state of the melt inside the machine body 1 in real time.Temperature sensor 20 on the outer wall of discharge port 14 monitors the temperature of the melt to be discharged in real time. Both sensors transmit the collected data to control panel 21, which is then displayed on screen 22. Operators can monitor melt flow and temperature in real time via screen 22. If abnormal flow rate or temperature deviation occurs, parameters such as motor speed 5 and heating ring 10 can be adjusted via control panel 21. For remote monitoring, wireless communication module 23 on one side of screen 22 transmits equipment operation data to a remote terminal, facilitating remote viewing and control by management personnel. Melt meeting requirements is discharged from discharge port 14 at the bottom of machine body 1. The uniform cooling ring 19 on the outer side of discharge port 14 activates, uniformly cooling the discharged melt to prevent internal stress caused by uneven cooling and ensure subsequent molding processing accuracy. Throughout the entire operation, vibration damping seat 25 at the bottom of machine body 1 continuously absorbs vibrations generated during operation, reducing impact and wear on components such as machine body 1, heating ring 10, and stirring rod 6, maintaining stable equipment operation, reducing vibration noise, and improving the workshop production environment.

[0021] To facilitate exhaust, such as Figure 1-2 As shown, an exhaust pipe 16 is fixedly installed on the top of the machine body 1, and a filter box 17 and a cooler 18 are fixedly installed on the wall of the exhaust pipe 16.

[0022] For ease of testing, such as Figure 2 As shown, a uniform cooling ring 19 and a temperature sensor 20 are fixedly provided on the outer wall of the discharge port 14.

[0023] For ease of operation, such as Figure 1 As shown, a control panel 21 is fixedly installed on the outer wall of the body 1, a display screen 22 is fixedly installed on the top of the control panel 21, and a wireless communication module 23 is fixedly installed on one side of the display screen 22.

[0024] Finally, for convenient water storage, such as Figure 1-2 As shown, a water storage box 24 is threaded on one side of the cooler 18, and a shock-absorbing seat 25 is fixed at the bottom of the body 1.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
