Description

Technical Field

[0001] The invention relates to the technical field of modified plastic particle production, in particular to a fast feeding device for producing modified plastic particles. Background Art

[0002] Modified plastic particles are a new type of material obtained by modifying plastic raw materials by adding various additives and fillers, or through physical and chemical methods. Modified plastic particles can be categorized according to the type of filler and additive, such as toughening modification, reinforcement modification, flame retardant modification, and UV resistance modification. Modified plastic particles can enhance properties such as hardness, strength, toughness, heat resistance, and compressive strength, thereby expanding their applications and improving product quality. Using modified plastic particles to produce plastic products can significantly reduce scrap rates, improve production efficiency, and minimize raw material waste. Modified plastic particles are widely used in the manufacture of various plastic products, including automotive parts, electrical housings, building materials, and daily necessities.

[0003] The main raw materials of plastic modified particles include various basic plastic resins, additives and reinforcing materials. When using these raw materials to prepare plastic modified particles, they need to be fed into the processing equipment with the help of relevant feeding equipment.

[0004] However, most of the feeding equipment in the prior art directly feeds the plastic granule raw materials during use. For example, if the plastic granule raw materials are already bagged and packaged, when they are fed into the feeding equipment, they need to be manually unpacked from the packaging bags on their surface, and then the opened plastic granule raw materials are poured into the feeding equipment. Manual unpacking of the packaging bags is cumbersome, and cutting the packaging bags with tools such as knives is dangerous, which makes the feeding efficiency of the packaged plastic granule raw materials low, thereby affecting the overall processing quality and efficiency of the plastic modified particles. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a fast feeding device for producing modified plastic particles.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A rapid feeding device for producing modified plastic particles comprises a box body, a filter plate for filtering the plastic particles is installed on the top of the box body, a first guide plate is installed on the outer wall of one side of the top of the box body, a second guide plate is rotatably installed on the outer wall of the other side of the top of the box body, a rubber plate is installed on the end of the second guide plate close to the rotating part, two fixed plates are installed on the top of the first guide plate, moving rods are provided on the tops of the two fixed plates, a driving mechanism for automatically pushing bagged materials is provided between the two moving rods, a rectangular block is installed between the first guide plate and the filter plate, a cutting mechanism for cutting the packaging bag of the bagged materials is installed inside the rectangular block, and a feeding mechanism for quantitatively discharging the plastic particles is installed inside the box body.

[0008] Optionally, a slide groove is provided on the top of the two fixed plates, a slider is installed inside the two slide grooves, and the bottom ends of the two movable rods are connected to the slider adjacent thereto.

[0009] Optionally, the driving mechanism includes a first groove opened on the outer wall of the two moving rods on the side close to each other, the inside of the two first grooves are both rotatably installed with screw rods, and the outer walls of the two screw rods are both threadedly installed with moving blocks.

[0010] Optionally, a first rotating plate is provided between the two moving blocks, and the first rotating plate is rotatably connected to the two moving blocks via rotating shafts provided on the outer walls on both sides.

[0011] Optionally, second rotating plates are rotatably mounted on outer walls on both sides of the bottom of the first rotating plate, and friction blocks are mounted on the bottoms of the two second rotating plates.

[0012] Optionally, a dust collection head is installed on the top of the first rotating plate, and a plurality of dust collection ports are opened at one end of the dust collection head away from the first rotating plate.

[0013] Optionally, the cutting mechanism includes a rectangular groove opened inside the rectangular block, two electric telescopic rods are installed on the inner bottom surface of the rectangular groove, and a mounting plate is commonly installed on the telescopic ends of the two electric telescopic rods.

[0014] Optionally, a plurality of mounting seats are installed on the top of the mounting plate, and a cutting knife is rotatably installed inside each of the mounting seats. A plurality of openings for the cutting knife to slide up and down are opened on the top of the rectangular block.

[0015] Optionally, the unloading mechanism includes a rotating drum rotatably installed inside the box body, a driving motor is installed on the outer wall of one side of the box body, the output end of the driving motor is connected to the rotating part of one end of the rotating drum, and a plurality of second grooves are opened on the outer wall of the rotating drum.

[0016] Optionally, the outer wall of the drum is further provided with a plurality of air outlets, and filters are installed inside the plurality of air outlets.

[0017] The beneficial effects of the present invention are:

[0018] 1. In this invention, when feeding the packaged bagged materials, the driving mechanism and the cutting mechanism cooperate with each other to automatically cut the packaging bags of the bagged materials, and push the discharged plastic granular raw materials to the top of the filter plate and fall downward into the interior of the box for temporary storage, thereby achieving the effect of automatically cutting and unloading such bagged materials, avoiding the problem of manual cutting of the packaging bags, which is more dangerous and has low feeding efficiency.

[0019] 2. In this invention, after the bagged material is placed on the top of the first guide plate, the second guide plate can also be controlled to rotate upward to a vertical state, blocking the end of the filter plate close to the second guide plate, thereby preventing the plastic particles subsequently escaping from the inside of the packaging bag from sliding from the top of the second guide plate and failing to accurately fall into the interior of the box. This can also simultaneously improve the accuracy of loading such bagged materials and allowing them to fall into the interior of the box.

[0020] 3. In this invention, after all the materials inside the cut packaging bag are discharged, the first rotating plate can be controlled to rotate clockwise and reset, and the two sliders can be controlled to move inside the corresponding slide to above the filter plate. The first rotating plate is driven downward by the two moving blocks, and after driving the two second rotating plates to contact the packaging bag, the two second rotating plates are controlled to rotate in the approaching direction until they are in contact with each other, and the packaging bag is automatically clamped and fixed. After the second guide plate is controlled to rotate downward and reset, as the two sliders move to the rightmost end, the two second rotating plates are controlled to rotate upward and reset, so that the packaging bag loses the clamping limit and is automatically discharged downward, avoiding the inconvenience of manually picking up the packaging bag.

[0021] 4. In this invention, if dust is present on the surface of the top stacked bagged materials during the storage process of bagged materials, the bagged materials with dust attached to the top are placed on the top of the first guide plate, and the two moving blocks are controlled to drive the first rotating plate and other components to move upward and adjust together, and then the first rotating plate is controlled to rotate counterclockwise upward to an inclined state, so that the dust collection head contacts the top of the bagged materials, and the dust on the top of the bagged materials can be automatically sucked away and cleaned with the help of multiple dust collection ports, thereby preventing subsequent dust from entering the interior of the box.

[0035] The technical solutions of the present invention will be described clearly and completely below with reference to the embodiments. It is obvious that the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0036] Reference Figures 1-11, a rapid feeding equipment for producing modified plastic particles, comprising a box body 1, a filter plate 5 for filtering the plastic particles is installed on the top of the box body 1, a first guide plate 2 is installed on the outer wall of one side of the top of the box body 1, and a rubber plate 30 is installed on the end of the second guide plate 3 close to the rotating part, and the second guide plate 3 is rotatably installed on the outer wall of the other side of the top of the box body 1, two fixed plates 4 are installed on the top of the first guide plate 2, and moving rods 6 are provided on the tops of the two fixed plates 4. A driving mechanism for automatically pushing the bagged material is provided between the two moving rods 6, a rectangular block 17 is installed between the first guide plate 2 and the filter plate 5, and a cutting mechanism for cutting the packaging bag of the bagged material is installed inside the rectangular block 17, and a feeding mechanism for quantitatively discharging the plastic particles is installed inside the box body 1. A first driving device is preset on the outer wall of one side of the box body 1, and the output end of the first driving device is connected to the rotating part of the second guide plate 3, so that the second guide plate 3 can be driven to rotate and adjust on the other side of the box body 1; in this embodiment, when the rotatably mounted second guide plate 3 is in a horizontal state, its height is higher than the filter plate 5, so that the bottom of the rubber plate 30 installed near the rotating part of the second guide plate 3 abuts against the top of the filter plate 5, and when the second guide plate 3 rotates upward and is in an inclined state, it will cause squeezing of the rubber plate 30, but because the rubber plate 30 is always located at the top of the filter plate 5, it can be ensured that the rubber plate 30 can block the gap between the second guide plate 3 and the box body 1, thereby avoiding the problem that some plastic particles are stuck in the gap between the second guide plate 3 and the box body 1 during the process of guiding the discharge of plastic particles by the second guide plate 3, and cannot accurately fall on the top of the filter plate 5.

[0037] As a technical optimization solution of the present invention, the tops of the two fixed plates 4 are each provided with a chute 19, inside which a slider 10 is mounted. The bottom ends of the two movable rods 6 are connected to the adjacent slider 10. Linear motors are pre-installed within each chute 19, driving the two sliders 10 to move back and forth within the corresponding chute 19, thereby driving the two movable rods 6 to move back and forth and adjust on the tops of the corresponding fixed plates 4.

[0038] As a technical optimization solution of the present invention, the drive mechanism includes a first groove 11 defined in the outer wall of the adjacent side of the two moving rods 6. A screw rod 14 is rotatably mounted within each of the first grooves 11, and a moving block 12 is threadedly mounted on the outer wall of each of the screw rods 14. A second drive device is pre-installed at the top of each of the moving rods 6. The output ends of the two second drive devices are respectively connected to the top ends of the two screw rods 14, thereby driving the two screw rods 14 to rotate and adjust within the corresponding first grooves 11, thereby driving the two moving blocks 12 to move up and down and adjust on the surfaces of the corresponding screw rods 14.

[0039] As a technical optimization solution of the present invention, a first rotating plate 7 is disposed between the two moving blocks 12. The first rotating plate 7 is rotatably connected to the two moving blocks 12 via rotating shafts 15 provided on the outer walls of both sides. A third drive device is pre-installed within one of the moving blocks 12. The output end of the third drive device is connected to one of the rotating shafts 15, which drives the first rotating plate 7 to rotate and adjust between the two moving blocks 12.

[0040] As a technical optimization solution of the present invention, second rotating plates 8 are rotatably mounted on the outer walls of both sides of the bottom of the first rotating plate 7, and friction blocks 13 are installed on the bottom of each of the two second rotating plates 8. Two fourth drive devices are pre-installed on the outer wall of the bottom side of the first rotating plate 7. The output ends of the two fourth drive devices are respectively connected to the rotating parts of the two second rotating plates 8, driving the two second rotating plates 8 to rotate and adjust on both sides of the bottom of the first rotating plate 7. The friction blocks 13 are metal plates with a roughened bottom surface.

[0041] As a technical optimization solution of the present invention, a dust suction head 9 is mounted on the top of the first rotating plate 7. A plurality of dust suction ports 16 are formed at one end of the dust suction head 9 away from the first rotating plate 7. When in use, the dust suction head 9 can be connected to an external pre-set dust suction device via a hose, so that the plurality of dust suction ports 16 generate suction during use to remove dust from the surface of the packaging bag.

[0042] As a technical optimization solution of the present invention, the cutting mechanism includes a rectangular slot 21 defined within the rectangular block 17. Two electrically operated telescopic rods 22 are mounted on the inner bottom surface of the slot 21. A mounting plate 23 is mounted to the telescopic ends of the two electrically operated telescopic rods 22. During the telescopic process, the telescopic ends of the two electrically operated telescopic rods 22 drive the mounting plate 23 to move up and down within the slot 21.

[0043] As a technical optimization solution of the present invention, a plurality of mounting seats 24 are mounted on the top of the mounting plate 23. Cutting knives 25 are rotatably mounted inside the plurality of mounting seats 24. A plurality of openings 20 for the cutting knives 25 to slide up and down are opened on the top of the rectangular block 17. When the mounting plate 23 is moved up and down within the rectangular groove 21, it can drive the plurality of mounting seats 24 and the cutting knives 25 installed therein to move up and down synchronously within the corresponding openings 20. When the plurality of cutting knives 25 extend from the corresponding openings 20, the packaging bag, upon contact with the plurality of cutting knives 25, is cut open, causing the plastic granular raw material inside the packaging bag to be discharged from the top of the filter plate 5 and downward into the interior of the box body 1.

[0044] As a technical optimization solution of the present invention, the unloading mechanism includes a rotating drum 18 rotatably mounted inside a housing 1. A drive motor 26 is mounted on one outer wall of the housing 1. The output end of the drive motor 26 is connected to a rotating portion at one end of the rotating drum 18. The outer wall of the rotating drum 18 is provided with a plurality of second grooves 27. After the drive motor 26 is started, it can drive the rotating drum 18 to rotate inside the housing 1. Plastic particles entering the housing 1 will flow into the second grooves 27. As the rotating drum 18 rotates, the plastic raw materials filled in the second grooves 27 are discharged from the bottom end of the housing 1 into the processing equipment, achieving the effect of automatic feeding.

[0045] As a technical optimization solution of the present invention, the outer wall of the drum 18 is further provided with multiple air outlets 28, each of which is equipped with a filter 29. Another rotating portion of the drum 18 can be connected to an external pipe, the other end of which is connected to an external hot air blower. The hot air generated by the external hot air blower can be transported through the pipe into the interior of the drum 18 and discharged outward through the multiple air outlets 28 into the interior of the housing 1, thereby drying the plastic particles entering the housing 1.

[0046] In the present invention, when the user uses the device, the box body 1 is installed at the top feed port of the processing equipment. If the plastic particles to be fed have been filled into the storage container, Figure 1 and Figure 11 As shown, first control the first rotating plate 7 to rotate 90 degrees counterclockwise between the two moving blocks 12, drive the two second rotating plates 8 to rotate to the right side in a vertical state, and then control the two screw rods 14 to rotate to drive the two moving blocks 12 to move downward together, and drive the first rotating plate 7 and the two second rotating plates 8 and other components to move downward together, until one of the second rotating plates 8 located below moves to abut against the top of the first guide plate 2, and then control the two sliders 10 to move in the corresponding chute 19 toward the direction close to the filter plate 5, drive the first rotating plate 7 and the two second rotating plates 8 to move to the top of one end of the filter plate 5, and then control the second guide plate 3 upward The rotation is in an inclined state. At this time, the discharge pipe matched with the discharge port of the storage container can be directly placed on the top of the second guide plate 3. The plastic particles discharged from the discharge pipe can move downward from the top of the second guide plate 3 to the top of the filter plate 5. The rubber plate 30 provided at this time can block the gap between the second guide plate 3 and the box body 1, so that all the plastic particles can fall on the top of the filter plate 5 and pass through the filter plate 5 downward into the interior of the box body 1. The two second rotating plates 8 and the first rotating plate 7 located at the top of one end of the filter plate 5 can limit the plastic particles moving to the top of the filter plate 5, preventing the plastic particles from moving to the top of the first guide plate 2, thereby ensuring that the plastic particles can be accurately discharged.

[0047] like Figure 5 and Figure 8 As shown, plastic pellets entering the housing 1 flow smoothly into one of the second grooves 27. As the drive motor 26 drives the drum 18 to rotate, the plastic pellets contained in the second grooves 27 rotate downward and are discharged downward from the bottom of the housing 1 into the processing equipment. Because the multiple second grooves 27 are of the same size, the volume of plastic pellets entering different second grooves 27 is also the same, achieving the effect of quantitatively feeding the plastic pellets from the housing 1 into the processing equipment. The quantitative discharge of plastic pellets by the drum 18 allows for continuous feeding and metering of plastic pellets, ensuring a stable and continuous material supply, thereby reducing production interruptions and improving overall production efficiency. Precise metering and control ensure a fixed amount of material is fed each time, avoiding product quality fluctuations caused by uneven material flow and improving product uniformity and consistency. This reduces the need for manual weighing and lowers labor costs. Furthermore, precise metering reduces material waste and raw material consumption, thereby saving costs. The system can be integrated with a production management system to provide accurate data support, facilitating production scheduling and quality control, and enhancing the scientific and efficient nature of production management.

[0048] If the plastic granule raw material to be fed is a packaged bag material, in order to avoid putting such bag material into the box body 1, the packaging bag needs to be manually disassembled or cut open, and finally the plastic granules filled in the packaging bag are poured into the box body 1. The process is relatively cumbersome. Figure 9As shown, the two sliders 10 are controlled to move to the leftmost end inside the corresponding slide grooves 19, and then the first rotating plate 7 is controlled to rotate 90 degrees counterclockwise to drive the two second rotating plates 8 to rotate to a vertical state. The first rotating plate 7 and the two second rotating plates 8 are driven downward together by the two screw rods 14 until one of the second rotating plates 8 at the bottom abuts against the top of the first guide plate 2. Then, the telescopic ends of the two electric telescopic rods 22 are controlled to extend upward together, pushing the mounting plate 23, multiple mounting seats 24 and cutting knives 25 to move upward together until the tops of the multiple cutting knives 25 pass through the corresponding openings 20 and move to the top of the rectangular block 17. Then, the bagged material is placed on the top of the first guide plate 2 and positioned between the two second rotating plates with the help of manual or mechanical hands. 8 and the filter plate 5, as the two sliders 10 are controlled to move toward the right end in the corresponding chute 19, the two second rotating plates 8 are driven to push the bagged material placed on the top of the first guide plate 2 to move toward the right end. After the packaging bag of the bagged material contacts the multiple cutting knives 25, the multiple cutting knives 25 can take advantage of the situation to cut and scratch the packaging bag of the bagged material, so that the plastic particles inside it are scattered on the top of the first guide plate 2 and the filter plate 5, and as the two second rotating plates 8 continue to move toward the right end, the scattered plastic particles are concentrated on the top of the filter plate 5 and fall downward into the interior of the box 1 for temporary storage, thereby achieving the effect of automatically cutting and unloading such bagged materials, avoiding the problem of manual cutting of the packaging bags, which is more dangerous and has low feeding efficiency;

[0049] At the same time, after the bagged material is placed on the top of the first guide plate 2, the second guide plate 3 can also be controlled to rotate upward to a vertical state, blocking the end of the filter plate 5 close to the second guide plate 3, thereby preventing the plastic particles that subsequently escape from the packaging bag from sliding from the top of the second guide plate 3 and failing to accurately fall into the box body 1. This can also simultaneously improve the accuracy of loading such bagged materials and allowing them to fall into the box body 1.

[0050] After all the materials inside the cut packaging bag are discharged, the first rotating plate 7 can be controlled to rotate clockwise to reset, and the two sliders 10 can be controlled to move inside the corresponding slide groove 19 to above the filter plate 5. With the help of the two moving blocks 12, the first rotating plate 7 is driven to move downward, and after driving the two second rotating plates 8 to contact the packaging bag, the two second rotating plates 8 are controlled to rotate downward in the direction of approaching each other, so that at this time, the two second rotating plates 8 are rotated in the direction of approaching each other to abutment state, and the packaging bag is automatically clamped and fixed. After the second guide plate 3 is controlled to rotate downward to reset, as the two sliders 10 move to the rightmost end, the two second rotating plates 8 are controlled to rotate upward to reset, so that the packaging bag loses the clamping limit and is automatically discharged downward, avoiding the inconvenience of manually picking up the packaging bag.

[0051] For example, during the storage of bagged materials, dust may be present on the surface of the bagged materials stacked on top. In order to prevent the dust on the surface of the packaging bag from mixing with the plastic particles when the plastic particles are put into the box 1, and falling into the box 1 together, thereby affecting the subsequent preparation of the modified plastic particles, such as Figure 10 As shown, after placing the bagged material with dust attached to the top on the top of the first guide plate 2, the two moving blocks 12 are controlled to drive the first rotating plate 7 and other components to move upward and adjust, and then the first rotating plate 7 is controlled to rotate upward counterclockwise to be in an inclined state, so that the dust suction head 9 contacts the top of the bagged material, and the dust on the top of the bagged material can be automatically sucked away and cleaned with the help of multiple dust suction ports 16, thereby preventing subsequent dust from entering the interior of the box 1.

[0052] If the plastic particles are not stored as required during storage, resulting in agglomerates inside the plastic particles, these agglomerates will be retained on the top of the filter plate 5. After all the plastic particles are placed inside the box 1, as shown in the following example, Figure 1 As shown, at this time, the first rotating plate 7 and the two second rotating plates 8 are in their original state, and the two sliders 10 are controlled to move inside the corresponding slide grooves 19, driving the first rotating plate 7 and the two second rotating plates 8 to move to the top of the filter plate 5 together. As the two screw rods 14 drive the two moving blocks 12 to move downward, the first rotating plate 7 and the two second rotating plates 8 are driven downward together, so that the two second rotating plates 8 press and crush the plastic particle agglomerates remaining on the top of the filter plate 5, and after crushing them into smaller parts, pass through the filter plate 5 downward into the interior of the box body 1, so that they can continue to be discharged from the bottom end of the box body 1 to the interior of the processing equipment for processing, thereby preventing these agglomerates from entering the interior of the box body 1, resulting in them being unable to be used for the production of plastic modified particles, thereby reducing the waste of plastic raw materials.

[0053] If the plastic particle agglomerates cannot be pressed and crushed by the two second rotating plates 8 and the first rotating plate 7, after the two second rotating plates 8 move downward until they come into contact with the plastic particle agglomerates, the two screw rods 14 can be controlled to continue rotating while the two sliders 10 are controlled to move back and forth inside the corresponding slide grooves 19, driving the two second rotating plates 8 to move back and forth on the top of the filter plate 5. While pressing and crushing the plastic particle agglomerates on the top of the filter plate 5, the friction blocks 13 at the bottom of the two second rotating plates 8 move back and forth to crush such plastic particle agglomerates that are difficult to be directly pressed and crushed, thereby improving the efficiency of processing such plastic particle agglomerates.

[0054] If the storage environment of the bagged materials is relatively humid, resulting in a certain amount of moisture in the plastic particles, the external preset hot air blower can be controlled to start while the plastic particles are temporarily stored inside the box 1, and the generated hot air can be transported to the inside of the drum 18 and discharged outward from multiple air outlets 28 to the inside of the box 1, thereby drying the plastic particles inside the box 1 at this time, avoiding the problem of directly feeding relatively wet plastic particles into the processing equipment, which would affect the production of plastic modified particles.
