Description

Technical Field

[0001] This utility model relates to the field of packaging device technology, specifically to a PPS composite material finished product packaging device that prevents dust pollution. Background Technology

[0002] In the field of polymer materials, polyphenylene sulfide (PPS) has become an indispensable material in high-end manufacturing due to its excellent performance. In order to further optimize the performance of PPS materials, the industry generally adopts the method of adding fillers to PPS matrix to prepare composite modified materials, and then processes them into PPS composite granules through extrusion granulation process for subsequent processing.

[0003] The current structure of granule packaging machines is generally as described in the granule packaging machine disclosed in patent application number "CN202120838132.7". The packaging machine includes a packaging table, a box, a receiving mechanism, a filling mechanism, a film unwinding mechanism, a forming device, a sealing mechanism, and an air inlet mechanism. The box is connected to the packaging table. The receiving mechanism is installed on the packaging table and extends into the box at one end to receive upstream material. The filling mechanism is located in the box and connected to the receiving mechanism. The forming device and the film unwinding mechanism are both installed on the packaging table. The filling mechanism is used to fill the film in the forming device with material from the receiving mechanism. The forming device is used to form the film containing material from the film unwinding mechanism. The sealing mechanism is located on the packaging table to seal and cut the formed film. The air inlet mechanism is connected to the packaging table to input compressed air into the box.

[0004] In the actual production process of PPS composite granulation, some filler powder adheres to the surface of the PPS composite granules. At the same time, the cutting action of the granulation cutter also causes tiny debris to be generated at the edges of some granules, further increasing the dust content on the granule surface. If the dust on the surface of the PPS composite granules is not cleaned before packaging, it will cause wear on the edges of the PPS composite granules, excessive stress on the packaging material, and damage, thereby reducing the yield of qualified products.

[0005] Therefore, this utility model proposes a PPS composite material finished product packaging device to prevent dust pollution, in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a packaging device for finished PPS composite materials that prevents dust pollution, in order to solve the problem in the prior art that dust generated during the production process can cause wear on the edges of PPS composite particles, excessive stress on the packaging material, and damage, thereby reducing the qualified rate of finished products.

[0007] The technical solution adopted by this utility model to solve its technical problem is: A dust-proof packaging device for PPS composite materials includes a base, a feeding tray, and a sealing machine. The feeding tray is connected to the base, and the sealing machine is located on one side of the base. The feeding tray includes a base frame, a first drive motor, a fixed base, and a rotating disk. The rotating disk is rotatably connected to the base frame, the first drive motor is connected to the base frame, and the fixed base is fixedly connected to the first drive motor. The drive shaft of the first drive motor is coaxially connected to the rotating disk. The rotating disk has multiple evenly spaced discharge holes, and the fixed base has discharge ports corresponding to the discharge holes. The fixed base has multiple evenly spaced dust collection holes, and a storage box is located at the lower end of the fixed base. A vacuum cleaner is connected to one side of the storage box and is connected to the base. A dust cover is connected to the base, and a feed pipe is connected to the dust cover, corresponding to any one of the discharge holes. A blower is connected inside the dust cover and is positioned corresponding to the discharge hole.

[0008] Furthermore, each of the feeding holes is rotatably connected to a stirring rod shaft, and multiple stirring blades are evenly connected to the stirring rod shaft. The stirring rod shaft is coaxially connected to the drive shaft of the second drive motor, which is located inside the rotating disk.

[0009] Furthermore, each of the fixed bases is provided with an arc-shaped groove corresponding to the dust collection hole.

[0010] Furthermore, the packaging machine includes a housing, on which a film roll component, a feeding plate, a shaping device, a longitudinal sealing component, a film traction component, and a transverse sealing component are sequentially connected from top to bottom. A tension adjusting component is provided between the film roll component and the feeding plate, and the tension adjusting component is rotatably connected to the housing via a telescopic connecting rod.

[0011] Furthermore, the feeding plate is located below the discharge port, the feeding plate is inclined, and the two sides of the feeding plate are connected with retaining edges.

[0012] Furthermore, a receiving box is provided below the discharge port, the receiving box is connected to the upper end of the feeding plate, and a baffle plate is connected above the baffle.

[0013] Furthermore, a conveying device is provided at the lower end of the transverse sealing component, and multiple limiting plates are evenly connected on the conveyor belt of the conveying device.

[0014] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: This invention can blow airflow into the feeding hole, which further blows away dust that has already detached from the material surface, suspending the dust in the feeding hole and preventing it from re-adhering to the material surface. This then activates the vacuum cleaner, creating negative pressure at the dust collection hole, which draws the suspended dust inside the dust cover into the collection box for collection. Through the combined action of blowing and vacuuming, dust on the surface of PPS composite granules is efficiently removed, preventing edge wear caused by surface dust, and preventing uneven stress on the packaging material due to dust particles, thus significantly reducing the defective product rate and greatly improving the finished product qualification rate.

[0015] The dust cover connected to the base of this utility model can prevent external dust from entering the device. The precise correspondence between the feed pipe and the discharge hole enables the sealed introduction of materials, avoiding secondary pollution of materials by external dust during the processing.

[0016] The receiving box below the discharge port of this utility model can buffer the falling material and prevent the material from directly impacting the feeding plate and causing damage. The inclined feeding plate, together with the side guards and the upper baffle, can not only realize the stable gravity conveying of the material, but also prevent the material from falling or colliding during the conveying process, further protecting the integrity of the material and reducing material loss caused by the conveying process.

[0017] The rotating stirring rod and stirring blades of this invention stir and disperse the PPS composite granules in the feeding hole, which can prevent the material from clumping during the falling process and cause poor feeding, and also remove the dust adhering to the surface of the material.

[0021] like Figure 1-6As shown, a PPS composite material finished product packaging device for preventing dust pollution includes a base 1, a feeding tray, and a sealing machine. The feeding tray is connected to the base 1, and the sealing machine is located on one side of the base 1. The feeding tray includes a base frame 2, a first drive motor 3, a fixed seat 4, and a rotating disk 5. The rotating disk 5 is rotatably connected to the base frame 2, the first drive motor 3 is connected to the base frame 2, and the fixed seat 4 is fixedly connected to the first drive motor 3. The drive shaft of the first drive motor 3 is coaxially connected to the rotating disk 5. The rotating disk 5 has a plurality of uniformly distributed discharge holes 6, and the fixed seat 4 has a discharge port 7 corresponding to the discharge holes 6. The fixed seat 4 has a plurality of uniformly distributed dust collection holes 8, and a storage box 9 is provided at the lower end of the fixed seat 4. A vacuum cleaner 10 is connected to one side of the storage box 9 and is connected to the base 1. The fixed seat 4 has an arc-shaped groove 11 corresponding to each dust collection hole 8. A dust cover 12 is connected to the base 1, and a feed pipe 13 is connected to the dust cover 12. The feed pipe 13 corresponds to any one of the discharge holes 6. A blower 14 is connected inside the dust cover 12, and the blower 14 is set corresponding to the discharge hole 6. A stirring rod shaft 15 is rotatably connected inside each of the discharge holes 6. Multiple stirring blades 16 are evenly connected to the stirring rod shaft 15. The stirring rod shaft 15 is coaxially connected to the drive shaft of the second drive motor 17, which is located inside the rotating disk 5.

[0022] Furthermore, the packaging machine includes a housing 18, on which, from top to bottom, are sequentially connected a film roll component 19, a feeding plate 20, a shaping device 21, a longitudinal sealing component 22, a film traction component 23, and a transverse sealing component 24. A tension adjusting component 25 is provided between the film roll component 19 and the feeding plate 20, and the tension adjusting component 25 is rotatably connected to the housing 18 via a telescopic connecting rod 26. The feeding plate 20 is located below the discharge port 7 and is inclined, with baffles 27 connected to both sides of the feeding plate 20. A receiving box 28 is located below the discharge port 7 and is connected to the upper end of the feeding plate 20, with a baffle plate 29 connected above the baffles 27. A conveying device 30 is located at the lower end of the transverse sealing component 24, and multiple limiting plates 31 are evenly connected to the conveyor belt of the conveying device 30.

[0023] The working process of this utility model is as follows: First, the PPS composite granules to be packaged are fed into the device through the feed pipe 13 on the dust cover 12. The feed pipe 13 corresponds to any one of the discharge holes 6 on the rotating disk 5, ensuring that the material falls accurately into the discharge hole 6. At the same time, the dust cover 12 can effectively isolate external dust from entering the device, avoiding secondary contamination of the material. After the material falls into the discharge hole 6, the second drive motor 17 starts, driving the stirring rod shaft 15 and stirring blades 16 to rotate, stirring and dispersing the PPS composite granules in the discharge hole 6. This prevents the material from clumping during the falling process, which would cause poor feeding, and also removes the dust adhering to the surface of the material. Then, the blower 14 starts, blowing air into the discharge hole 6. The airflow will further blow away the dust that has been removed from the surface of the material, making the dust suspend in the discharge hole 6, preventing the dust from re-adhering to the surface of the material.

[0024] The fixed base 4 has multiple dust collection holes 8 evenly distributed, and each fixed base 4 has an arc-shaped groove 11 corresponding to the dust collection hole 8. The arc-shaped groove 11 design can increase the range of dust entering the dust collection hole 8 and improve the dust collection efficiency. The lower end of the fixed base 4 is provided with a storage box 9. A vacuum cleaner 10 is connected to one side of the storage box 9. The vacuum cleaner 10 is connected to the base 1. When the vacuum cleaner 10 is started, a negative pressure is formed at the dust collection hole 8, which draws the dust suspended in the dust cover 12 into the storage box 9 for collection. Then, through the combination of blowing and vacuuming, the dust on the surface of PPS composite granules is efficiently removed.

[0025] Simultaneously, the first drive motor 3 starts, driving the rotating disk 5 to rotate and perform cleaning. Then, the discharge hole 6 containing the cleaned material rotates to the position corresponding to the discharge port 7 on the fixed base 4. Then, the material in the discharge hole 6 falls into the receiving box 28 below under its own gravity. The receiving box 28 is connected to the upper end of the feeding plate 20 and can buffer and guide the material during the unloading process, avoiding direct impact of the material on the feeding plate 20 and causing damage. Then, the material in the receiving box 28 will slide onto the feeding plate 20. The inclined feeding plate 20 can use gravity to make the material slide down automatically, realizing the material conveying. The side guard 27 and the baffle plate 29 can prevent the material from falling from both sides of the feeding plate 20 during the conveying process, ensuring that the material can be stably conveyed to the subsequent packaging components.

[0026] The packaging film then unfolds from the film roll component 19, passing first through the tension adjusting component 25 between the film roll component 19 and the feeding plate 20. The tension adjusting component 25 is rotatably connected to the machine housing 18 via a telescopic connecting rod 26. The position of the tension adjusting component 25 can be adjusted by changing the length of the telescopic connecting rod 26 according to the material and thickness of the packaging film, thereby adjusting the tension of the packaging film to maintain appropriate tightness and prevent breakage due to excessive tension or loose packaging due to insufficient tension. The tension-adjusted packaging film is then conveyed to the shaping device 21, which shapes the packaging film into a cylindrical structure suitable for wrapping materials. Simultaneously, the material on the feeding plate 20 is conveyed into the cylindrical packaging film, completing the wrapping of the material. The packaging film containing the material is then conveyed to the longitudinal sealing component 22, which heat-seals the longitudinal seams of the packaging film to ensure a firm longitudinal seal and prevent material leakage from the longitudinal seams. After the longitudinal sealing is completed, the film traction component 23 is activated, driving the packaging film containing the material to continue being conveyed downwards to the transverse sealing component 24. The transverse sealing component 24 performs transverse heating and sealing on the packaging film, and at the same time, cuts the continuous packaging film into individual packaged products according to the set packaging length.

[0027] A conveying device 30 is provided at the lower end of the transverse sealing component 24. Multiple limiting plates 31 are evenly connected on the conveyor belt of the conveying device 30. A single packaged product will fall onto the conveyor belt of the conveying device 30. The limiting plates 31 can position the packaged product and prevent it from shifting during the conveying process. Finally, the conveying device 30 will transport the packaged product to the designated position to complete the entire packaging process of the PPS composite material product.
