Description

Technical Field

[0001] This invention relates to the field of plastic processing technology, and more specifically to a plastic granule melting device for plastic processing. Background Technology

[0002] In the plastics processing industry, melting plastic granules is a crucial pre-processing step for subsequent processes such as injection molding and extrusion. Traditional plastic melting equipment typically uses a simple heating tank with a stirring paddle. While it can achieve basic melting functionality, it still faces numerous technical bottlenecks and shortcomings in practical production applications.

[0003] First, the stirring efficiency and melting uniformity are poor. Existing stirring mechanisms are mostly fixed or single-rotor types. As the viscosity of plastic granules gradually increases during melting, they easily clump together and adhere to the stirring paddle or the inner wall of the tank. A fixed stirring rod cannot effectively scrape off the adhering material from the inner wall, leading to uneven heating. This not only prolongs the melting time but also easily causes localized overheating and decomposition, affecting the quality of the plastic melt. Furthermore, a single rotation method is insufficient for effectively shearing and mixing materials of different viscosities, resulting in incomplete melting.

[0004] Secondly, environmental performance is insufficient, and flue gas treatment is difficult. During the high-temperature melting process, plastic granules generate large amounts of volatile organic compounds (VOCs) and dust. Most existing melting equipment lacks effective sealing and flue gas collection devices, or only has simple exhaust vents, resulting in the direct release of harmful gases into the workshop air, severely polluting the environment and endangering the health of operators. Even when some equipment is equipped with purification devices, leaks often occur during feeding, mixing, or discharging due to unreasonable sealing structure design, significantly reducing the purification effect.

[0005] Secondly, cleaning is difficult and lacks automation. In a multi-variety, small-batch production model, frequent changes in plastic color or material are common. However, solidified plastic easily remains inside the stirring shaft and cylinder of existing equipment. Cleaning often requires manual disassembly of the equipment or scraping with tools, which is not only time-consuming and labor-intensive, increasing labor costs, but also can easily lead to color differences or impurities in the next batch of products, affecting product yield.

[0026] Please refer to Figure 3 and Figure 4 As shown, the moving mechanism 3 also includes a drive motor 306 fixedly installed on the top of the movable block 305. The output end of the drive motor 306 is fixedly connected to the first rotating plate 307. An electric motor 308 is provided on the outer wall of the first rotating plate 307.

The two output ends of the first dual-axis electric push rod 312 are both fixedly installed with a first clamping member 313.

[0027] Those skilled in the art will understand that by controlling the two output ends of the first dual-axis electric actuator 312 to retract synchronously, the two sets of first clamping members 313 are brought closer to each other, thereby clamping the outer wall of the fixing rod 202 and fixing the placement cylinder 102; by controlling the output end of the first stepper motor 304 to rotate, the first lead screw 302 is rotated, which drives the movable block 305 to move horizontally back and forth along the outer wall of the first guide rod 303, thereby driving the placement cylinder 102 in the clamping state to move horizontally back and forth. In addition, by controlling the output end of the electric push rod 310 to extend or retract, the mounting part 311 is driven to move downward or upward, thereby driving the placement cylinder 102 in the clamped state to move downward or upward; and by controlling the output end of the motor 308 to rotate, the placement cylinder 102 in the clamped state is driven to flip. Example 4

[0028] Please refer to Figure 2 and Figure 7 As shown, the flue gas exhaust assembly includes a connecting pipe 104, a cylinder 105, a suction pump 106, and a hose 107. The cylinder 105 and the suction pump 106 are both fixedly installed on the back of the high-temperature chamber 101. The output end of the cylinder 105 extends into the high-temperature chamber 101 and is fixedly connected to the connecting pipe 104.

A hole 103 is provided on the outer wall of the placement cylinder 102.

[0029] Please refer to Figure 6 and Figure 7 As shown, the sealing mechanism 4 includes a second lead screw 401 and a sealing plate 404. The second lead screw 401 is rotatably connected to the outside of the high-temperature chamber 101. The sealing plate 404 is provided with two sets of threads respectively connected to the two ends of the outer wall of the second lead screw 401. The threads at both ends of the second lead screw 401 are turned in opposite directions. A second guide rod 402 is also fixedly installed on the outside of the high-temperature chamber 101. The sealing plate 404 is slidably connected to the second guide rod 402. A second stepper motor 403 is fixedly connected to the outside of the high-temperature chamber 101. The output end of the second stepper motor 403 is fixedly connected to the outer end of the second lead screw 401. Both sets of sealing plates 404 have slots 405 that are adapted to the fixed rod 202 through them on the side that is close to each other.

[0030] Those skilled in the art will understand that by controlling the output end of the second stepper motor 403 to rotate, the second lead screw 401 is driven to rotate, thereby causing the two sets of sealing plates 404 to move closer to or further away from each other; Therefore, under the extension of the output end of the electric push rod 310, the placement cylinder 102 in the clamping state moves downward, so that the height of the fixed rod 202 matches the height of the two sets of sealing plates 404. Then, under the action of the output end of the second stepper motor 403, the two sets of sealing plates 404 move closer to each other, so that the slots 405 on the two sets of sealing plates 404 fit with the surface of the fixed rod 202, achieving a seal. At this time, the bottom of the two sets of sealing plates 404 also fits with the top of the placement cylinder 102. The high-temperature chamber 101... The purification liquid inside is heated to a high temperature. The placement cylinder 102 is made of a high thermal conductivity material, which can melt the plastic particles inside the placement cylinder 102. The plastic particles will generate smoke and dust during the melting process. By controlling the output end of the cylinder 105 to extend, the connecting pipe 104 is inserted into the hole 103 on the placement cylinder 102. The air pump 106 is started, which can draw the generated smoke and dust into the purification liquid to purify it and prevent the smoke and dust from entering the external environment, thus protecting the environment. Example 5

[0031] Please refer to Figure 2 and Figure 7 As shown, the drive mechanism 5 includes a third lead screw 501 and a third guide rod 502. Both the third lead screw 501 and the third guide rod 502 are provided in two sets. The third lead screw 501 is rotatably connected inside the high-temperature chamber 101, and the third guide rod 502 is fixedly installed inside the high-temperature chamber 101. Both sets of third lead screws 501 are threadedly connected to racks 504. One set of racks 504 meshes with a gear ring 203, and the other set of racks 504 meshes with a gear 205. Two sets of third stepper motors 503 are installed on the outer wall of the high-temperature chamber 101. The output ends of the two sets of third stepper motors 503 are fixedly connected to the outer ends of the two sets of third lead screws 501 respectively.

[0032] Those skilled in the art will understand that by controlling the output of the third stepper motor 503 to rotate, the third lead screw 501 can be rotated, thereby driving the rack 504 to perform horizontal reciprocating motion. The two sets of racks 504 can respectively drive the gear ring 203 and the gear 205 to rotate. Example 6

[0033] Please refer to Figure 8As shown, the cleaning mechanism 6 includes a fixed frame 601 fixedly installed on the rear side of the top of the substrate 1. A fourth lead screw 602 is rotatably connected inside the fixed frame 601. A lifting block 605 is threadedly connected to the fourth lead screw 602. The lifting block 605 is slidably connected to the outer wall of the fourth guide rod 603. The fourth guide rod 603 is fixedly installed inside the fixed frame 601. A fourth stepper motor 604 is provided on the top of the fixed frame 601. The output end of the fourth stepper motor 604 extends into the fixed frame 601 and is fixedly connected to the fourth lead screw 602. A second dual-axis electric push rod 606 is fixedly installed inside the lifting block 605. A second clamping member 607 is fixedly connected to both output ends of the second dual-axis electric push rod 606.

[0034] Please refer to Figure 9 As shown, the cleaning mechanism 6 also includes a hydraulic rod 608 fixedly installed on the top of the collection box 108. The output end of the hydraulic rod 608 extends into the collection box 108 and is fixedly connected to the lifting member 609. The top of the lifting member 609 is fixedly connected to the first cleaning member 611 and the second cleaning member 612 through two sets of connecting members 610. The outer diameter of the first cleaning member 611 is adapted to the inner diameter of the placement cylinder 102, and the size of the second cleaning member 612 is adapted to the size of the square rod 201.

[0035] Those skilled in the art will understand that by controlling the output end of the fourth stepper motor 604 to rotate, the fourth lead screw 602 rotates, thereby driving the lifting block 605 to move up and down along the outer wall of the fourth guide rod 603, thus driving the two sets of second clamping members 607 to move up and down; and by controlling the output end of the hydraulic rod 608 to extend or retract, the first cleaning member 611 and the second cleaning member 612 are driven to move downward or upward as a whole.

[0036] To clearly describe the working principle of this invention, we will use... Figure 1 The explanation is based on a directional perspective, as follows: S1. Plastic granules are automatically poured into the interior of the placement cylinder 102 by an external feeding device. Under the action of the extension of the output end of the electric push rod 310, the placement cylinder 102 in the clamping state is driven to move downward, so that the height of the fixing rod 202 is matched with the height of the two sets of sealing plates 404. S2. By controlling the output end of the second stepper motor 403 to rotate, the second lead screw 401 is rotated, which in turn causes the two sets of sealing plates 404 to move closer to each other, so that the slots 405 on the two sets of sealing plates 404 are in contact with the surface of the fixing rod 202 to achieve sealing. At this time, the bottom of the two sets of sealing plates 404 is also in contact with the top of the placement cylinder 102. By controlling the output end of the cylinder 105 to extend, the connecting pipe 104 is inserted into the hole 103 on the placement cylinder 102. S3. The high-temperature chamber 101 heats the purification liquid inside to a high temperature. The placement cylinder 102 is made of a high thermal conductivity material, thereby melting the plastic particles inside the placement cylinder 102. During the melting process, one set of racks 504 is driven to move horizontally, causing the gear 205 to rotate. This causes the rotating rod 204 and the first bevel gear 206 to rotate as a whole, which in turn causes the second bevel gear 208 and the threaded rod 207 to rotate as a whole. This causes the movable plate 209 to reciprocate, thereby causing several sets of stirring rods 210 to extend to the outside of the square rod 201. When another set of racks 504 is driven to move horizontally, causing the gear ring 203 to rotate, the fixed rod 202, the square rod 201, and several sets of stirring rods 210 can rotate as a whole, stirring the plastic particles during the heating process and preventing them from melting incompletely. In addition, during this process, the plastic particles will generate smoke and dust as they melt. By starting the air pump 106, the generated smoke and dust gas can be drawn into the purification liquid to purify it, preventing the smoke and dust gas from entering the external environment and protecting the environment. S4. After the smoke and dust gas is purified, the two sets of sealing plates 404 are reset. Under the action of the retraction of the output end of the electric push rod 310, the placement cylinder 102 is driven to move upward. Under the combined action of the output end of the first step motor 304, the output end of the drive motor 306 and the output end of the motor 308, the placement cylinder 102 moves to the external collection device and flips over, so as to pour the melted plastic liquid inside into the collection device. S5. When it is necessary to melt plastic granules of other colors, to prevent the solidified residual plastic on the placement cylinder 102, square rod 201 and several sets of stirring rods 210 from affecting the color change, the placement cylinder 102 is put back into the high-temperature chamber 101 and the gear 205 is driven to rotate, so that several sets of stirring rods 210 extend into the interior of the square rod 201, and the scraper directly scrapes off the solidified plastic on the stirring rods 210; then, under the combined action of the output end of the first step motor 304 and the output end of the motor 308, the placement cylinder 102 moves to the top of the collection box 108 and flips over. At this time, the two output ends of the second dual-axis electric push rod 606 retract synchronously, driving the two sets of second clamping parts 607 to move closer to each other, thereby fixing the inverted placement cylinder 102; The two output ends of the first dual-axis electric actuator 312 extend synchronously, and the two sets of first clamping members 313 move away from each other, releasing the clamping of the placement cylinder 102. Then, by controlling the output end of the fourth stepper motor 604 to rotate, the clamped inverted placement cylinder 102 moves downward and enters the collection box 108. Finally, under the action of the extension or retraction of the output end of the hydraulic rod 608, the first cleaning member 611 and the second cleaning member 612 move downward or upward as a whole, thereby scraping the end walls of the square rod 201 and several sets of stirring rods 210 as well as the inner wall of the placement cylinder 102, thus achieving cleaning. It is convenient and quick, meeting the needs of the staff.
