Description

Technical Field

[0001] This utility model relates to the field of plastic recycling equipment, specifically an anti-clogging structure for a recycled plastic melt extrusion granulator. Background Technology

[0002] With the rapid development of society, there is an increasing amount of plastic waste in daily life. However, plastic waste is difficult to degrade, and direct disposal will cause serious environmental pollution. To address the plastic problem, an extrusion granulator for recycling waste plastic has been developed. By recycling plastic and regenerating it into granules, it can not only reduce environmental pollution but also create new value.

[0003] Traditional pelletizers often experience feed clogging during the feeding process due to the varying shapes of plastic waste, which can cause it to accumulate and negatively impact performance. Furthermore, the presence of iron filings in the plastic can affect the quality of the melt-extruded pellets. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an anti-clogging structure for a recycled plastic melt extrusion granulator. This solves the technical problem that when the current granulator is feeding, the plastic waste of different shapes accumulates together, which easily causes blockage at the feed inlet, affecting the performance. Furthermore, the iron filings contained in the plastic affect the quality of recycled plastic melt extrusion granulation.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A clog-proof structure for a recycled plastic melt extrusion granulator is designed, including:

[0006] An anti-clogging component is fixed at the feed inlet of the extrusion granulator body;

[0007] The anti-blocking component includes:

[0008] A feeding hopper, the top of which is fixedly connected to a storage cylinder;

[0009] The filter cartridge is located in the middle of the inner cavity of the storage cylinder and is used to filter recycled plastic before it is fed into the body of the extrusion granulator.

[0010] A crushing and conveying mechanism is provided between the filter cylinder and the feed hopper, and is used to crush recycled plastic and push the crushed recycled plastic to be conveyed.

[0011] A drive mechanism is located at the top of the storage cylinder and is used to drive the crushing and conveying mechanism to rotate. The drive end of the drive mechanism is connected to the input end of the crushing and conveying mechanism.

[0012] Preferably, the crushing and conveying mechanism includes a drive shaft rotatably connected to the bottom end of the inner cavity of the filter cylinder via a bearing. The bottom end of the drive shaft extends through the filter cylinder into the feed hopper. A crushing blade is fixedly connected to the outside of the drive shaft inside the filter cylinder, and a spiral blade is fixedly connected to the outside of the drive shaft inside the feed hopper.

[0013] Preferably, the driving mechanism includes a connecting plate disposed on the top of the filter cylinder, and a driving motor is fixedly connected to the top center of the connecting plate. The driving end of the driving motor rotates through the connecting plate and is connected to the driving shaft through a coupling.

[0014] Preferably, a magnetic cover is provided on the inner wall of the feed hopper above the spiral blades, and a support mechanism is provided between the magnetic cover and the inner wall of the feed hopper.

[0015] Preferably, the support mechanism includes a support ring fixedly connected to the inner wall of the feed hopper below the magnet cover. The surface of the support ring is provided with a slot. A locking block is fixedly connected to one end of the magnet cover near the support ring, and the locking block corresponds to and is compatible with the slot.

[0016] Preferably, the top of the filter cylinder is fixedly connected to a guide hopper, and the outer side of the top of the guide hopper is movable against the inner wall of the storage cylinder. The top of the guide hopper and the top of the storage cylinder are on the same horizontal plane, and the top of the guide (6) is fixedly connected to the bottom of the connecting plate.

[0017] Preferably, both sides of the top of the connecting plate are rotatably connected to fixing bolts, and the fixing bolts are threadedly connected to the surface of the storage cylinder.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By crushing and conveying the recycled plastic before it enters the extrusion granulator, the blockage at the feed inlet caused by the accumulation of plastic waste of different shapes is avoided. At the same time, the filter cartridge can filter the crushed recycled plastic to ensure the uniformity of the material entering the extrusion granulator. It can also push the crushed recycled plastic from the feed hopper into the extrusion granulator to prevent waste from accumulating at the feed inlet of the extrusion granulator. This achieves integrated operation of crushing and conveying, further ensuring the smoothness of feeding.

[0020] 2. The magnetic cover utilizes magnetic force to attract iron filings, separating them from the recycled plastic and preventing them from entering the extrusion granulator body. This avoids affecting the quality of the melt-extruded granulation of recycled plastic and also reduces wear on internal parts of the extrusion granulator caused by iron filings, extending the equipment's service life.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: Anti-clogging structure of recycled plastic melt extrusion granulator, see [link / reference] Figures 1 to 3 ,include:

[0027] An anti-clogging component is fixed at the feed inlet of the extrusion granulator body 1;

[0028] The anti-blocking component includes:

[0029] Feed hopper 2, the top of which is fixedly connected to a storage cylinder 21;

[0030] The filter cylinder 35 is located in the middle of the inner cavity of the storage cylinder 21 and is used to filter recycled plastic before it is added into the body 1 of the extrusion granulator.

[0031] A crushing and conveying mechanism is provided between the filter cylinder 35 and the feed hopper 2, and is used to crush recycled plastic and push the crushed recycled plastic to be conveyed.

[0032] A drive mechanism is located at the top of the storage cylinder 21 and is used to drive the crushing and conveying mechanism to rotate. The drive end of the drive mechanism is connected to the input end of the crushing and conveying mechanism.

[0033] In use, an anti-clogging component is installed at the feed inlet of the extrusion granulator body 1. The top of the feed hopper 2 is fixedly connected to the storage cylinder 21. A filter cylinder 35 is installed in the middle of the inner cavity of the storage cylinder 21. A crushing and conveying mechanism is installed between the filter cylinder 35 and the feed hopper 2. A drive mechanism is installed at the top of the storage cylinder 21 to drive the crushing and conveying mechanism to rotate. This structural design allows the recycled plastic to be crushed by the crushing and conveying mechanism before entering the extrusion granulator body 1, avoiding the blockage of the feed inlet caused by the accumulation of plastic waste of different shapes. At the same time, the filter cylinder 35 can filter the crushed recycled plastic to ensure the uniformity of the material entering the extrusion granulator body 1. It can also push the crushed recycled plastic from the feed hopper 2 into the extrusion granulator body 1 to prevent waste from accumulating at the feed inlet of the extrusion granulator body 1, realizing the integrated operation of crushing and conveying, and further ensuring the smoothness of feeding.

[0034] For details, see Figure 2 The crushing and conveying mechanism includes a drive shaft 32 rotatably connected to the bottom of the inner cavity of the filter cylinder 35 via a bearing. The bottom end of the drive shaft 32 extends through the filter cylinder 35 into the feed hopper 2. A crushing blade 34 is fixedly connected to the outside of the drive shaft 32 inside the filter cylinder 35, and a spiral blade 33 is fixedly connected to the outside of the drive shaft 32 inside the feed hopper 2. When the drive shaft 32 is rotated by the drive mechanism, the crushing blade 34 can fully crush the recycled plastic in the storage cylinder 21, crushing plastic waste of different shapes into smaller particles, reducing the possibility of accumulation and clogging of the feed inlet. At this time, the spiral blade 33 also rotates with the drive shaft 32, which can push the crushed recycled plastic from the feed hopper 2 into the extrusion granulator body 1.

[0035] Further, see Figure 2 The driving mechanism includes a connecting plate 3 disposed on the top of the filter cylinder 35. A drive motor 31 is fixedly connected to the top center of the connecting plate 3. The drive end of the drive motor 31 rotates through the connecting plate 3 and is connected to the drive shaft 32 through a coupling. This driving method enables the drive motor 31 to stably provide power to the drive shaft 32, ensuring the rotation efficiency of the crushing blade 34 and the spiral blade 33. This ensures the crushing and conveying effect of the crushing and conveying mechanism on recycled plastics, allowing the anti-clogging component to work continuously and effectively, and avoiding the problem of feed inlet blockage caused by insufficient power leading to incomplete crushing or poor conveying.

[0036] It is worth mentioning that, see Figure 2The top of the filter cylinder 35 is fixedly connected to a guide hopper 5, and the outer side of the top of the guide hopper 5 is movable against the inner wall of the storage cylinder 21. The top of the guide hopper 5 and the top of the storage cylinder 21 are on the same horizontal plane, and the top of the guide hopper 5 is fixedly connected to the bottom of the connecting plate 3. This structure can guide the recycled plastic in the storage cylinder 21 to the central area of ​​the filter cylinder 35, avoiding the accumulation of material at the junction of the storage cylinder 21 and the filter cylinder 35 to form a dead corner. At the same time, through the guiding effect of the guide hopper 5, the material falls evenly into the filter cylinder 35, and in conjunction with the crushing and conveying mechanism, more orderly crushing processing is achieved, effectively improving the smoothness of the feeding process and the material processing efficiency.

[0037] It is worth mentioning that, see Figure 3 The top two sides of the connecting plate 3 are rotatably connected by fixing bolts 36, and the fixing bolts 36 are threaded to the surface of the storage cylinder 21. The detachable fixing method facilitates quick disassembly of the drive mechanism. When it is necessary to inspect the crushing blade 34, the spiral blade 33 or the filter cylinder 35, simply loosen the fixing bolts 36 to separate the connecting plate 3 from the storage cylinder 21. This greatly reduces the difficulty of equipment maintenance, shortens downtime for maintenance, and ensures the stability of the drive mechanism after installation, avoiding the impact of loose connecting parts on the operating accuracy of the crushing and conveying mechanism.

[0038] It is worth noting that, see Figure 2 and Figure 3 A magnetic cover 4 is provided on the inner wall of the feed hopper 2 above the spiral blade 33. A support mechanism is provided between the magnetic cover 4 and the inner wall of the feed hopper 2. The support mechanism includes a support ring 41 fixedly connected to the inner wall of the feed hopper 2 below the magnetic cover 4. A slot 43 is formed on the surface of the support ring 41. A locking block 42 is fixedly connected to one end of the magnetic cover 4 near the support ring 41. The locking block 42 corresponds to and fits the slot 43. Since recycled plastic may contain iron filings, the magnetic cover 4 can use magnetic force to attract the iron filings. This process separates the iron filings from the recycled plastic, preventing them from entering the extrusion granulator body 1 and affecting the quality of the melt extrusion granulation of the recycled plastic. It also reduces the wear of the internal parts of the extrusion granulator body 1 by the iron filings, extending the service life of the equipment. When a large amount of iron filings are adsorbed on the magnet cover 4, the connecting plate 3 can be disassembled. Since the guide hopper 5 is fixedly connected to the connecting plate 3, the filter cartridge 35 can be taken out, and the magnet cover 4 can be taken out from above the storage cylinder 21, making it easier to clean the adsorbed iron filings.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
