Description

Technical Field

[0001] This invention relates to the field of masterbatch melting and processing technology, specifically to a biodegradable masterbatch melting and processing apparatus and method. Background Technology

[0002] In today's society, where environmental awareness is increasingly strong, biodegradable materials have received widespread attention and rapid development due to their environmentally friendly characteristics. Biodegradable masterbatch, as the basic raw material for producing various biodegradable products, directly affects the performance and market application of the final product through its processing quality. The melting and processing of biodegradable masterbatch is a crucial step in the entire production process, requiring extremely high melting efficiency and uniformity, which directly relates to the quality stability and production efficiency of subsequent products. Currently, some biodegradable masterbatch melting and processing devices exist on the market. While these existing devices have achieved certain results in masterbatch melting and processing, they still reveal many shortcomings in practical applications, making it difficult to meet the growing demand for high-quality production.

[0003] In terms of stirring and melting, the existing equipment has a relatively simple stirring method, usually only using simple rotary stirring. This single stirring mode cannot achieve all-round and multi-angle stirring of the material in the stirring area, resulting in the masterbatch not being able to fully contact the heat during the stirring process, and the melting speed is slow. Moreover, due to uneven stirring, it is very easy to have local overheating or some masterbatch not melting, resulting in poor quality consistency of masterbatch melting and seriously affecting the quality of the final product.

[0004] Feed control is also a weakness of the existing equipment. The existing feed control methods lack flexibility and are difficult to adjust in a timely manner according to the precise requirements of the masterbatch feed amount at different processing stages. The discharge port size of some equipment is fixed and cannot adapt to the different feed speed requirements due to process changes during production. This results in poor adaptability and controllability of the equipment, reducing production efficiency and product quality. Even if some equipment has feed adjustment function, the adjustment method is not precise and stable enough to achieve accurate control of the feed speed and cannot make timely and accurate adjustments according to the actual situation in the processing process, which further affects the stability of production and the uniformity of product quality. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a biodegradable masterbatch melting and processing apparatus and method, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a biodegradable masterbatch melting and processing device, comprising a box body, a feeding channel provided on one side of the top of the box body, a discharging channel provided on one side of the bottom of the box body, and a melting auxiliary component for assisting the rapid melting of biodegradable masterbatch provided inside the box body;

[0011] As a further preferred embodiment of this technical solution, a movable plate is rotatably connected to the bottom of the feeding channel, and movable seats are movably arranged on both sides of the movable plate. A vertical rod is provided on the top of the movable seat, and the vertical rod is slidably installed on the feeding channel in the vertical direction. A first damping spring is sleeved on the outer wall of the vertical rod.

[0012] As a further preferred embodiment of this technical solution, a support frame is fixedly installed on one side of the top of the inner cavity of the box. A control rod is slidably connected to the bottom of the support frame. One end of the control rod contacts the bottom of the movable plate. A fixing block is fixedly connected to the outer wall of the control rod. A movable rod is fixedly connected to the bottom of the fixing block. A tension spring sleeved on the control rod is provided between the fixing block and the support frame.

[0013] As a further preferred embodiment of this technical solution, connecting plates are fixedly connected to both sides of the control rod, and striking rods are slidably connected to the connecting plates in the vertical direction. The two striking rods are located at the bottom of the movable plate. Limiting blocks are fixedly connected to the upper outer wall of the striking rods, and a fourth damping spring is sleeved on the striking rods between the limiting blocks and the connecting plates.

[0014] As a further preferred embodiment of this technical solution, a second crossbar is fixedly connected to the bottom of the two striking rods, a second crossbar is fixedly connected to one side of the outer wall of the second crossbar, a second guide rod is slidably connected to the other end of the second crossbar, and a fifth damping spring is sleeved on the outer wall of the second crossbar to push the second guide rod to move to one side.

[0015] As a further preferred embodiment of this technical solution, a fixed rod is fixedly connected to the top of the rectangular frame, an installation rod is slidably connected to the top of the fixed rod, a sliding rod is fixedly connected to the side wall of the installation rod, and one end of the sliding rod is slidably installed in a circular groove. A rotating ring is fixedly connected to the top of the installation rod. The outer wall of the rotating ring is provided with a first protrusion in a circumferential array, and the positions of the first protrusion and the movable rod correspond to each other. The inner wall of the rotating ring is provided with a second protrusion in a circumferential array, and the positions of the second protrusion and the second guide rod correspond to each other.

[0016] This invention also discloses a processing method for a biodegradable masterbatch melting and processing device, specifically including the following steps:

[0017] Step 1: The degradation masterbatch to be melted is fed into the box through the feeding channel for melting. The degradation masterbatch inside the box can be melted by turning on the heating wire.

[0018] Step 2: Turn on the drive motor to drive the spline rod, sleeve, rectangular frame, first crossbar, movable ring, and stirring rod to rotate synchronously. When the first guide rod contacts the trapezoidal block, it guides the first guide rod, rectangular frame, and sleeve to move upward and compress the third damping spring. When they disengage, the third damping spring pushes the sleeve and rectangular frame downward, causing the rectangular frame, stirring rod, and gear to move up and down reciprocally. The rack causes the gear to rotate, which in turn drives the first crossbar, movable ring, and stirring rod to rotate. At the same time, the reciprocating block and the second damping spring cause the movable ring and stirring rod to move laterally reciprocally. The combination of these multiple movements enables the stirring rod to stir in all directions and at multiple angles.

[0019] Step 3: When the rectangular frame rotates, it drives the fixed rod, mounting rod, sliding rod, rotating ring, first protrusion, and second protrusion to rotate synchronously. When the first protrusion contacts the movable rod, it pushes the movable rod to move outward and stretches the tension spring. The first damping spring pushes the movable plate to move downward, expanding the feed channel outlet. When the first protrusion disengages, the tension spring pulls the control rod to move inward, and the movable plate moves upward, making the outlet smaller and slowing down the discharge speed. When the second protrusion contacts the second guide rod, it causes the striking rod to move downward and compress the fourth damping spring. When it disengages, the fourth damping spring pushes the striking rod upward to strike the bottom of the movable plate, causing it to vibrate. This makes the degradation masterbatch discharge smoother and more evenly distributed, improving melting efficiency and quality, breaking up agglomerates, and ensuring stable and smooth processing.

[0020] Compared with existing technologies, it has the following advantages:

[0021] Efficient melting and uniform stirring

[0022] Composite motion stirring rod: The stirring rod can achieve all-round and multi-angle stirring in the stirring area through the composite motion of up-and-down reciprocating movement, rotation and lateral reciprocating movement. This composite motion mode greatly improves the uniformity and efficiency of stirring, allowing the biodegradable masterbatch to come into more full contact with heat, accelerating the melting speed, effectively avoiding local overheating or unmelted situations, and ensuring the consistency of masterbatch melting quality.

[0023] Trapezoidal block guides up and down reciprocating motion: The ingenious design of the first guide rod and the trapezoidal block guides the first guide rod, rectangular frame, sleeve and other components to move up and down reciprocally through the inclined surface of the trapezoidal block, thereby driving the stirring rod to move up and down. This rhythmic up and down reciprocating motion further enhances the stirring effect, breaks the static state of the masterbatch in the box, promotes the uniform transfer of heat and improves melting efficiency.

[0024] Gear and rack drive rotation: The meshing connection between the gear and the rack allows the stirring rod to rotate while moving up and down. This rotational motion, combined with the up-and-down reciprocating motion, forms a unique stirring method that can better break up agglomerates of masterbatch and make the masterbatch come into more full contact with heat, thereby greatly improving stirring efficiency and shortening melting time.

[0025] Flexible feed control

[0026] Adjustable discharge port with movable plate: The movable plate design at the bottom of the feed channel, through the coordinated action of the movable seat, vertical rod and first damping spring, can flexibly adjust the size of the discharge port at the bottom of the feed channel according to actual needs. When it is necessary to speed up the feeding, the movable plate rotates downward and the discharge port becomes larger; conversely, when it is necessary to slow down the feeding speed, the movable plate rotates upward and the discharge port becomes smaller. This flexible feeding control method can meet the requirements of masterbatch feeding amount at different processing stages and improve the adaptability and controllability of the device.

[0027] Precise mechanical linkage control: The mechanical linkage between the first protrusion on the rotating ring and the movable rod enables precise control of the position of the movable plate. When the first protrusion contacts the movable rod, it pushes the movable rod outward, causing the movable plate to rotate downward and widen the discharge port. When the first protrusion is not in contact with the movable rod, the tension spring pulls the movable rod inward, causing the movable plate to rotate upward and narrow the discharge port. This mechanical linkage design makes the adjustment of the feeding speed more precise and stable, and can make timely adjustments according to the actual situation in the processing.

[0028] Preventing blockages and ensuring even material feeding

[0029] Vibration anti-clogging with striking rod: The periodic striking of the bottom of the moving plate by the striking rod generates vibration that effectively prevents the degradation masterbatch from accumulating and clogging on the moving plate. The vibration makes it easier for the masterbatch to detach from the moving plate and smoothly enter the box for processing, ensuring the continuity and stability of feeding. At the same time, the vibration can also create a certain scattering effect on the masterbatch, making the masterbatch more evenly distributed during the fall and allowing it to come into more full contact with the heat in the processing environment, thereby significantly improving the melting efficiency and quality of the degradation masterbatch.

[0030] The second protrusion drives the striking motion: the second protrusion on the rotating ring, in conjunction with the second guide rod, enables the striking rod to move up and down. When the second protrusion contacts the second guide rod, it pushes the second guide rod downward, causing the striking rod to move downward and compress the fourth damping spring. When the second protrusion is not in contact with the second guide rod, the fourth damping spring releases its elastic potential energy, pushing the striking rod upward to strike the bottom of the movable plate. This design cleverly utilizes the principle of mechanical linkage to ensure the accuracy and timeliness of the striking action, further enhancing the anti-clogging and uniform material feeding effects.

[0031] Good heat insulation and cleaning performance

[0032] Double-layer insulation: The box adopts a unique double-layer structure design. Heating wires are installed in the inner groove formed between the inner and outer layers. This design can not only effectively heat and melt the degradation masterbatch inside the box, but also play a certain role in insulation through the double-layer structure, reducing heat loss and improving energy utilization efficiency. Compared with the traditional single-layer structure box, the double-layer structure can better maintain the temperature stability inside the box, reduce energy consumption, and save production costs.

[0033] Scraper cleaning of the inner wall: The scraper fixedly connected to the outer wall of the rectangular frame can effectively prevent the degradation masterbatch from adhering and accumulating on the inner wall of the box. During the rotation of the rectangular frame, the scraper will scrape the inner wall of the box to ensure the cleanliness of the inside of the box. This not only helps to evenly transfer heat and improve melting efficiency, but also extends the service life of the box and reduces the maintenance cost of the equipment. At the same time, the clean inner wall can also prevent masterbatch residue from contaminating subsequent processing and ensure product quality. Attached Figure Description

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1: Combining Figures 1-8 As shown, the present invention provides a technical solution: a biodegradable masterbatch melting and processing device, including a box 1, which serves as the core container for the entire processing process. A feeding channel 2 is carefully provided on one side of the top of the box to facilitate the smooth entry of the biodegradable masterbatch into the box. A discharge channel 4 is provided on one side of the bottom to discharge the melted masterbatch from the box, thereby achieving the continuity of the processing flow.

[0045] The box 1 adopts a unique double-layer structure design, with an inner groove 11 cleverly formed between the inner and outer layers. A heating wire 12 is installed in the inner groove 11. This design can not only effectively heat and melt the degradation masterbatch inside the box 1, but also provide a certain degree of heat preservation through the double-layer structure, reducing heat loss and improving energy utilization efficiency. A circular groove 13 is opened at the upper end of the inner wall of the box 1, providing space and guidance for the movement of some components. At the same time, trapezoidal blocks 14 are arranged in a circumferential array on the inner wall of the box 1. These trapezoidal blocks 14 will play an important guiding role in the subsequent processing.

[0046] Inside the housing 1, there is a melting auxiliary component 3 specifically designed to assist in the rapid melting of the degradation masterbatch. The core of this component is a drive motor 31 fixedly installed on the top of the housing 1. The drive motor 31 serves as the power source for the entire auxiliary component, and its output end is fixedly connected to a spline rod 32. The spline rod 32 has precise transmission performance, ensuring stable power transmission. A sleeve 33 is slidably connected to the outer wall of the spline rod 32 in the vertical direction. This sliding connection allows the sleeve 33 to move up and down on the spline rod 32. Three sets of rectangular frames are arranged in a circumferential array on the outer wall of the sleeve 33. 34. This layout makes the stirring structure more uniform and reasonable, and can cover a larger stirring area. Multiple first horizontal bars 36 are rotatably connected to the inner side of the rectangular frame 34. The first horizontal bars 36 serve as the support structure for the stirring rods 38, providing a basis for their rotation. A movable ring 37 is laterally slidably connected to the outer wall of the first horizontal bars 36. Multiple stirring rods 38 for melting and stirring the degradation masterbatch are arranged in a circular array on the outer wall of the movable ring 37. These stirring rods 38 are rationally designed to effectively stir the degradation masterbatch, promote full contact with heat, and accelerate the melting speed.

[0047] Multiple movable rings 37 are fixedly connected by connecting rods 39 to form an integral stirring structure, which enhances the stability and coordination of stirring. One end of the connecting rod 39 is provided with a reciprocating block 311 fixedly installed on the rectangular frame 34. The reciprocating block 311 provides guidance and restriction for the lateral reciprocating movement of the movable rings 37. The outer wall of the other end of the connecting rod 39 is fitted with a second damping spring 310, and one end of the second damping spring 310 is fixedly connected to the inner wall of the rectangular frame 34. Under the elastic force of the second damping spring 310, the end of the connecting rod 39 is pushed to fit tightly against the reciprocating block 311, so that the movable rings 37 can move laterally and reciprocally under the combined action of the second damping spring 310 and the reciprocating block 311, further enhancing the stirring effect.

[0048] A third damping spring 314 is provided on the top of the sleeve 33 and sleeved on the spline rod 32. The third damping spring 314 provides elastic power for the reciprocating up and down movement of the sleeve 33. A gear 312 is fixedly installed at the end of the first crossbar 36. A toothed bar 313 is meshed with one side of the gear 312 and fixedly connected to the top of the spline rod 32. When the sleeve 33 moves up and down under the action of the third damping spring 314, it will drive the first crossbar 36 to move up and down. The meshing connection between the gear 312 and the toothed bar 313 causes the gear 312 to rotate while moving up and down, thereby driving the first crossbar 36, the movable ring 37 and the stirring rod 38 to rotate synchronously, realizing the compound motion of the stirring rod 38 and greatly improving the stirring efficiency.

[0049] A scraper 35 for scraping the inner wall of the box 1 is fixedly connected to the outer wall of the rectangular frame 34. The design of the scraper 35 can effectively prevent the degradation masterbatch from adhering and accumulating on the inner wall of the box 1, ensuring the cleanliness of the inside of the box 1, and also helping to distribute heat evenly. A first guide rod 315 is fixedly connected to the top of the scraper 35, and the position of the first guide rod 315 corresponds to that of the trapezoidal block 14. When the drive motor 31 drives the spline rod 32, sleeve 33 and rectangular frame 34 to rotate synchronously, the rectangular frame 34 can drive the first guide rod 315 to rotate synchronously. When the first guide rod 315 rotates to When in contact with the trapezoidal block 14, the first guide rod 315 will be subjected to an upward component force under the guidance of the trapezoidal block 14, thereby causing the first guide rod 315, the rectangular frame 34, and the sleeve 33 to move upward and compress the third damping spring 314. When the first guide rod 315 rotates to no longer contact the trapezoidal block 14, the third damping spring 314 pushes the sleeve 33 and the rectangular frame 34 downward under the elastic force, thereby causing the rectangular frame 34 and the stirring rod 38 to move up and down reciprocally, forming a rhythmic stirring action, which further improves the melting effect of the degradation masterbatch.

[0050] Furthermore, during the rotation of the rectangular frame 34, a series of related components can work together to achieve more functions. For example, the rotation of the rectangular frame 34 can drive the fixed rod, the mounting rod and other components to rotate synchronously. When a specific protrusion contacts the movable rod, it can push the movable rod and related control components to move, thereby changing the size of the feed channel outlet and realizing flexible control of the feeding speed of the biodegradable masterbatch. At the same time, when another protrusion contacts the guide rod, it can make the striking rod move up and down to strike the bottom of the movable plate, causing the movable plate to vibrate. This prevents the biodegradable masterbatch from accumulating and clogging on the movable plate, and also makes the biodegradable masterbatch more evenly distributed during the falling process, improving melting efficiency and quality. Through the precise cooperation and coordinated work of each component, the entire device achieves efficient and stable melting and processing of biodegradable masterbatch.

[0051] In an embodiment of the present invention, by turning on the drive motor 31, its powerful output can quickly and stably drive the spline rod 32 connected to it to rotate synchronously. With its unique structural design and precise transmission characteristics, the spline rod 32 efficiently transmits the rotational power to the sleeve 33. Driven by the spline rod 32, the sleeve 33 is tightly fitted with the rectangular frame 34, and the two rotate synchronously. The rectangular frame 34 further drives the first crossbar 36, and the movable ring 37 sleeved on the first crossbar 36 also rotates accordingly. The stirring rod 38 fixedly connected to the movable ring 37 then begins its initial rotational motion, laying the foundation for subsequent complex stirring actions.

[0052] During the stirring process, as the first guide rod 315 gradually approaches and eventually rotates to contact the trapezoidal block 14 with the rotation of the overall structure, the unique inclined surface design of the trapezoidal block 14 plays a key role. Under the guidance of the trapezoidal block 14, the first guide rod 315 is subjected to an upward component force, which is transmitted to the rectangular frame 34 and the sleeve 33 in sequence, causing them to move upward against gravity. During the upward movement, the third damping spring 314 is compressed. The third damping spring 314 stores elastic potential energy, providing energy reserves for the subsequent reset action. As the first guide rod 315 continues to rotate, when it rotates to the point where it no longer contacts the trapezoidal block 14, the previously compressed third damping spring 314 begins to release elastic potential energy. Under the push of the elastic force of the third damping spring 314, the sleeve 33 and the rectangular frame 34 quickly move downward and return to near their initial positions. This process is repeated, enabling the rectangular frame 34, the stirring rod 38, and the gear 312 connected to it to move up and down reciprocally.

[0053] During the reciprocating motion of the rectangular frame 34, the gear 312 and the fixed rack 313 cooperate with each other. When the gear 312 moves up and down, due to the tooth structure of the rack 313, the gear 312 will rotate under the action of the rack 313. This rotation is not a simple rotation, but a compound motion combined with the reciprocating motion. The gear 312 transmits the rotational power to the first horizontal bar 36 through its connection with the first horizontal bar 36. The first horizontal bar 36 then drives the movable ring 37 and the stirring rod 38 to rotate synchronously, so that the stirring rod 38 rotates continuously while moving up and down, further enhancing the stirring effect. At the same time, the combination of the reciprocating block 311 and the second damping spring 310 forms the stirring rod. 38 provides lateral reciprocating motion power. Under the constraints of a specific track or structure, the reciprocating block 311 makes periodic lateral movements under the action of the second damping spring 310. Since there is a mechanical connection between the reciprocating block 311 and the movable ring 37, when the reciprocating block 311 moves laterally, it will drive the movable ring 37 to move together. The movable ring 37 is fixedly connected to the stirring rod 38, so the stirring rod 38 will also move laterally reciprocating. This combination of lateral reciprocating movement, up-and-down reciprocating movement and rotational motion enables the stirring rod 38 to achieve all-round and multi-angle stirring in the stirring area, which greatly improves the uniformity and efficiency of stirring and can better meet various complex stirring needs.

[0054] Example 2: Combination Figure 6 , Figure 7 , Figure 8As shown, based on Embodiment 1, a movable plate 21 is rotatably connected to the bottom of the feeding channel 2. Movable seats 22 are cleverly and movably arranged on both sides of the movable plate 21. A vertical rod 23 is installed on the top of the movable seat 22. The vertical rod 23 is precisely slidably installed on the feeding channel 2 in the vertical direction, and a first damping spring 24 is sleeved on the outer wall of the vertical rod 23. The first damping spring 24 continuously pushes the movable plate 21 to rotate downward by its own elastic force. When the movable plate 21 rotates downward, the discharge port at the bottom of the feeding channel 2 becomes larger, which means that the degradation masterbatch is discharged from the feeding channel 2 faster and can enter the box 1 for subsequent processing more quickly. Conversely, when the movable plate 21 rotates upward, the discharge port at the bottom of the feeding channel 2 becomes smaller, and the discharge speed of the degradation masterbatch slows down, thereby realizing flexible control of the feeding speed of the degradation masterbatch to meet the needs of different processing stages.

[0055] A support frame 322 is securely fixedly installed on one side of the top of the inner cavity of the housing 1. The bottom end of the support frame 322 is laterally slidably connected to the control rod 323. One end of the control rod 323 is in close contact with the bottom of the movable plate 21. A fixing block 324 is fixedly connected to the outer wall of the control rod 323. The bottom end of the fixing block 324 is fixedly connected to the movable rod 326. A tension spring 325 is provided between the fixing block 324 and the support frame 322 and sleeved on the control rod 323. The tension spring 325 is always in an elastic storage state. Under the elastic force, it pulls the fixing block 324, the movable rod 326, and the control rod 323 to move towards one side of the movable plate 21, which provides a guarantee for the reset and stable operation of the control rod 323.

[0056] The control lever 323 is fixedly connected to the connecting plates 327 on both sides. The connecting plates 327 are slidably connected to the striking rods 328 in the vertical direction, and the two striking rods 328 are precisely located at the bottom of the movable plate 21. The upper outer wall of the striking rods 328 is fixedly connected to the limiting block 329. A fourth damping spring 330 is provided between the limiting block 329 and the connecting plate 327 and is sleeved on the striking rods 328. Under the elastic force, the fourth damping spring 330 continuously pushes the striking rods 328 to move upward, so that the striking rods 328 can periodically strike the bottom of the movable plate 21. The vibration generated by this striking can cause the material discharged from the feed channel 2 to be discharged. The degradation masterbatch detaches from the moving plate more smoothly, effectively avoiding the accumulation and blockage of degradation masterbatch on the moving plate. Moreover, the vibrating moving plate 21 can also create a certain scattering effect on the degradation masterbatch. This scattering effect is of great significance. It makes the degradation masterbatch more evenly distributed during the fall, and can more fully contact the heat in the processing environment, thereby significantly improving the melting efficiency and quality of the degradation masterbatch. At the same time, the scattering process can also break up any possible agglomeration to a certain extent, allowing the degradation masterbatch to participate in subsequent processing in a looser and more independent state, providing a strong guarantee for the stability and smoothness of the entire processing process.

[0057] Two striking rods 328 are fixedly connected to the bottom of a second crossbar 331. Another second crossbar 331 is fixedly connected to one side of its outer wall (this design could be optimized to enhance stability or achieve other functions). The other end of the second crossbar 331 is laterally slidably connected to a second guide rod 332. A fifth damping spring 333 is fitted on the outer wall of the second crossbar 331 to push the second guide rod 332 to one side. Under the elastic force of the fifth damping spring 333, the end of the second guide rod 332 can be precisely pushed to slide against the inner wall of the rotating ring 319, ensuring that the second guide rod 332 can respond promptly and produce corresponding actions during the rotation of the rotating ring 319. 319. When the second protrusion 321 rotates and contacts the second guide rod 332, under the force of the second protrusion 321, the second guide rod 332 will overcome the elastic force of the fifth damping spring 333, causing the second crossbar 331, the striking rod 328 and the limiting block 329 to move downward and compress the fourth damping spring 330, accumulating energy for the subsequent striking action. When the second protrusion 321 rotates to the point where it is no longer in contact with the second guide rod 332, under the combined elastic force of the fifth damping spring 333 and the fourth damping spring 330, the limiting block 329 and the striking rod 328 will be pushed upward, realizing the striking action of the striking rod 328 on the bottom of the movable plate 21, producing a vibration effect.

[0058] A fixed rod 316 is fixedly connected to the top of the rectangular frame 34, and a mounting rod 317 is slidably connected to the top of the fixed rod 316. This sliding connection allows the mounting rod 317 to move flexibly within a certain range. A sliding rod 318 is fixedly connected to the side wall of the mounting rod 317, and one end of the sliding rod 318 is precisely slidably installed in the circular groove 13. The circular groove 13 provides a track and constraint for the sliding of the sliding rod 318, ensuring the stability of the sliding rod 318's movement. A rotating ring 319 is fixedly connected to the top of the mounting rod 317. As a key component, the rotating ring 319 has a first protrusion 320 arranged in a circumferential array on its outer wall, and the positions of the first protrusion 320 and the movable rod 326 correspond to each other, so as to achieve precise mechanical linkage during rotation. The inner wall of the rotating ring 319 has a second protrusion 321 arranged in a circumferential array, and the positions of the second protrusion 321 and the second guide rod 332 correspond to each other. The number of the first protrusion 320 and the second protrusion 321 can be flexibly set according to actual processing needs and design requirements to meet different work rhythms and effects.

[0059] In an embodiment of the present invention, when the rectangular frame 34 rotates under the drive of the driving device, the rotating ring 319, the first protrusion 320, and the second protrusion 321 can rotate synchronously through the coordinated action of components such as the fixed rod 316, the mounting rod 317, and the sliding rod 318. When the first protrusion 320 contacts the movable rod 326, an outward thrust is generated, pushing the movable rod 326, the fixed block 324, and the control rod 323 to move outward and stretching the tension spring 325. As the control rod 323 moves outward... During the process, the elastic force of the first damping spring 24 is released, pushing the movable plate 21 to move downward, thereby expanding the outlet of the feed channel 2 and accelerating the discharge speed of the degraded masterbatch. When the first protrusion 320 is not in contact with the movable rod 326, the tension of the tension spring 325 begins to play a role, pulling the control rod 323 to move inward, causing the movable plate 21 to rotate upward under the action of the relevant components. The outlet at the bottom of the feed channel 2 becomes smaller, and the discharge speed of the degraded masterbatch slows down, thus realizing the dynamic adjustment of the feed speed.

[0060] Under the action of the rotation of the second protrusion 321, when it comes into contact with the second guide rod 332, it will apply a downward pressure to the second guide rod 332, causing the second guide rod 332, the second crossbar 331, and the striking rod 328 to move downward and compress the fourth damping spring 330 to store elastic potential energy. When the second protrusion 321 rotates to the point where it no longer comes into contact with the second guide rod 332, the fourth damping spring 330 releases its elastic potential energy, pushing the striking rod 328 to move upward, causing the striking rod 328 to strike the bottom of the movable plate 21 and generate vibration. This ingenious mechanical linkage design makes the whole device perform well in terms of feeding control and smooth discharge of masterbatch, providing a solid guarantee for the efficient melting and processing of biodegradable masterbatch.

[0061] This invention also discloses a processing method for a biodegradable masterbatch melting and processing device, specifically including the following steps:

[0062] Step 1: The degradation masterbatch to be melted is fed into the box 1 through the feeding channel 2 for melting. The degradation masterbatch inside the box 1 can be melted by turning on the heating wire 12.

[0063] Step 2: Turn on the drive motor 31 to drive the spline rod 32, sleeve 33, rectangular frame 34, first crossbar 36, movable ring 37, and stirring rod 38 to rotate synchronously. When the first guide rod 315 contacts the trapezoidal block 14, it guides the first guide rod 315, rectangular frame 34, and sleeve 33 to move upward and compress the third damping spring 314. When they are out of contact, the third damping spring 314 pushes the sleeve 33 and rectangular frame 34 downward, causing the rectangular frame 34, stirring rod 38, and gear 312 to move up and down reciprocally. The rack 313 causes the gear 312 to rotate, which in turn drives the first crossbar 36, movable ring 37, and stirring rod 38 to rotate. At the same time, the reciprocating block 311 and the second damping spring 310 cause the movable ring 37 and stirring rod 38 to move laterally reciprocally. The combination of multiple movements enables the stirring rod 38 to stir in all directions and at multiple angles.

[0064] Step 3: When the rectangular frame 34 rotates, it drives the fixed rod 316, mounting rod 317, sliding rod 318, rotating ring 319, first protrusion 320, and second protrusion 321 to rotate synchronously. When the first protrusion 320 contacts the movable rod 326, it pushes the movable rod 326 to move outward and stretches the tension spring 325. The first damping spring 24 pushes the movable plate 21 to move downward and expand the discharge port of the feed channel 2. When the first protrusion 320 disengages, the tension spring 325 pulls the control rod 323 to move inward. The movable plate 21 moves upward, making the discharge port smaller and the discharge speed slower. When the second protrusion 321 contacts the second guide rod 332, it causes the striking rod 328 to move downward and compress the fourth damping spring 330. When it disengages, the fourth damping spring 330 pushes the striking rod 328 upward and strikes the bottom of the movable plate 21, causing it to vibrate. This makes the discharge of the degradation masterbatch smoother and more even, improves melting efficiency and quality, breaks up agglomerates, and ensures stable and smooth processing.
