Description

Technical Field

[0001] The present invention belongs to the technical field of plastic product packaging, and more specifically, particularly relates to an integrated packaging device for granular plastic products. Background Art

[0002] Plastic pellets refer to granular plastic products. When processing plastic pellets, different-sized plastic pellets are mixed. Therefore, before packaging plastic pellets, it is necessary to screen plastic pellets of different sizes. Otherwise, the quality of plastic pellet products will be affected. However, the existing plastic product packaging devices have the following defects: In the prior art, when a plastic product packaging device screens plastic pellets, a vibration motor is usually installed at the bottom of the screening shell, and the vibration motor is used to drive the screening shell to vibrate to screen the plastic pellets; however, this vibration method easily causes the plastic pellets to move too fast along the sieve plate direction, resulting in small-sized plastic pellets in the upper layer being unable to be effectively screened out, thereby reducing the screening efficiency of the device; moreover, the plastic pellets themselves have a certain elasticity, and if the vibration force is too large, the plastic pellets will bounce out of the screening shell, thus increasing the difficulty of screening.

[0003] In the prior art, in order to improve the screening effect on plastic pellets, a plastic product packaging device uses a servo motor to drive the screening shell to swing back and forth, so that the plastic pellets and residues stay for a longer time, and at the same time, it does not affect the natural dropping of the plastic pellets, thus improving the screening effect between the plastic pellets and plastic residues; however, since some plastic pellets are prone to moisture absorption, if the storage environment has high humidity, the pellets will absorb moisture from the air and agglomerate. The agglomerated pellets are difficult to evenly fill the package during packaging, which may lead to inaccurate package weight and affect the melting effect and product performance in subsequent processing.

[0004] In the prior art, in order to separate the agglomerated plastic pellets, a plastic product packaging device usually uses a limiting plate to extrude the agglomerated plastic pellets. However, simply squeezing the limiting plate downward is difficult to quickly separate the agglomerated plastic pellets, thereby affecting the quality and efficiency of the screening and packaging of plastic pellets.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an integrated packaging device for granular plastic products is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: An integrated sub-packaging device for granular plastic products of the present invention, through the first guide plate, the screening shell, and the steering gear, forms an S-shaped channel inside the screening shell by using two groups of first guide plates, thereby prolonging the residence time of plastic particles in the screening shell; then uses the steering gear to drive the screening shell to swing back and forth inside the outer shell. By using the back-and-forth swing of the screening shell, the plastic particles can stay in the upper part of the screening shell for a long time, increasing the probability of contact between the plastic particles and a plurality of filter holes, so as to improve the screening effect, and thereby screen out smaller plastic particles and impurities by using the plurality of filter holes.

[0018] An integrated packaging device for granular plastic products of the present invention, through the settings of the movable plate and the limiting plate, utilizes the movable plate and the limiting plate to limit the piled plastic particles, reducing the piled plastic particles, and utilizes the reciprocating movement of the movable plate and the limiting plate to disperse the piled plastic particles evenly. Further, through the setting of the fixed block, when the movable plate moves towards the fixed block, the upper side of one end of the movable plate contacts the inclined surface of one end of the fixed block, and the movement of the movable plate is guided by the fixed block, so that the movable plate moves downward. The downward movement of the movable plate drives the connecting block and the limiting plate to move downward. The downward movement of the movable plate and the limiting plate gradually reduces the height of the piled plastic particles limited, which is beneficial to reciprocatingly move and scrape the piled plastic particles layer by layer evenly, and the downward movement of the limiting plate squeezes and separates the agglomerated plastic particles. Finally, through the settings of the connecting block, the first spring, the movable block and the ejector rod, under the guiding action of the uneven structure on the upper part of the movable block and the elastic force of the first spring, during the reciprocating movement of the movable plate, the connecting block and the limiting plate can swing back and forth slightly. The repeated squeezing and patting of the agglomerated plastic particles by the slight back-and-forth swing of the connecting block and the limiting plate and the back-and-forth movement of the limiting plate is beneficial to separating the agglomerated plastic particles, thereby improving the screening effect.

[0019] An integrated packaging device for granular plastic products of the present invention, through the settings of the rotating shaft and the brush block, the reciprocating swing of the movable plate drives several rotating shafts and brush blocks to move back and forth, and the back-and-forth movement of several brush blocks cleans the impurities adsorbed on the surface of the plastic particles. And the downward movement of the movable plate drives several rotating shafts and brush blocks to move downward, so as to gradually improve the cleaning effect of the brush blocks on the impurities on the surface of the plastic particles, which is beneficial to quickly cleaning and removing the impurities and reducing the influence on the quality of the plastic products. Further, through the settings of the gear, the rack and the torsion spring, under the meshing action of the rack and the gear and the elastic force of the torsion spring, the rotating shaft and the brush block can rotate back and forth. The cooperation of the back-and-forth rotation of several rotating shafts and brush blocks, the back-and-forth movement of several rotating shafts and brush blocks and the downward movement of several rotating shafts and brush blocks can greatly improve the cleaning effect on the impurities on the surface of the plastic particles.

A dispensing pipe 40 is installed on the lower side of the second collection box 39.

[0038] The specific usage method of the present invention: The staff puts plastic particles into the funnel 11, and the plastic particles fall into the upper part of the screening shell 14 through the funnel 11. The staff operates the stepping motor 30 and the servo 32 to start through the control box 12. The servo 32 drives the screening shell 14 to swing back and forth within the outer shell 13. By using the back-and-forth swing of the screening shell 14, the plastic particles can stay in the upper part of the screening shell 14 for a long time, increasing the probability of the plastic particles coming into contact with a number of filter holes 15, thereby improving the screening effect, and then screening out the smaller plastic particles and impurities through the number of filter holes 15. The smaller plastic particles and impurities fall into the first collection tank 34 through the number of filter holes 15.

[0039] Secondly, when the screening shell 14 swings to one side, the swing of the screening shell 14 drives a number of push rods 17 to move. One end of the push rod 17 is in sliding contact with the inner wall of the arc-shaped guide block 44, and the movement of the push rod 17 is guided by the arc-shaped guide block 44, so that the push rod 17 moves closer to the inside of the screening shell 14. The movement of the push rod 17 drives the V-shaped plate 18 and the movable plate 19 to move, and the movement of the movable plate 19 drives the connecting block 42 and the limiting plate 41 to move. The movable plate 19 and the limiting plate 41 are used to limit the piled-up plastic particles, reducing the piled-up plastic particles. Among them, the movement of the push rod 17 drives the slide plate 45 to move, and the movement of the slide plate 45 compresses the elastic member 46 to generate an elastic force. Under the elastic force of the elastic member 46, the push rod 17 can move back to its original position.

[0040] At the same time, the movable plate 19 moves in the direction close to the fixed block 25. One end of the upper side of the movable plate 19 is in contact with the inclined surface of one end of the fixed block 25, and the movement of the movable plate 19 is guided by the fixed block 25, so that the movable plate 19 moves downward. The downward movement of the movable plate 19 drives the connecting block 42 and the limiting plate 41 to move downward. The downward movement of the movable plate 19 and the limiting plate 41 gradually reduces the height of the piled-up plastic particles limited, which is conducive to scraping and moving the piled-up plastic particles back and forth layer by layer evenly. Among them, the downward movement of the movable plate 19 makes the slider 54 slide in the chute 53, and the sliding of the slider 54 compresses the third spring 55 to generate an elastic force. Under the elastic force of the third spring 55, the movable plate 19 can move back to its original position upward.

[0041] When the screening shell 14 swings to the other side, under the elastic force of the elastic member 46, the push rod 17 moves back to its original position. The movable plate 19 moves in the direction away from the fixed block 25. Under the elastic force of the third spring 55, the movable plate 19 moves back to its original position upward. The movable plate 19 and the limiting plate 41 can move back and forth, and the piled-up plastic particles are dispersed evenly by the back-and-forth movement of the movable plate 19 and the limiting plate 41.

[0042] Therefore, as the screening housing 14 swings back and forth, the two sets of push rods 17 alternately move toward the center of the interior of the screening housing 14, which helps adjust the height at which the several movable plates 19 and the limiting plates 41 limit the accumulated plastic particles. Furthermore, the sieving housing 14 swings to one side, which causes all the plastic particles to move toward one side, so that a large number of plastic particles are evenly scraped layer by layer by the movable plates 19 and the limiting plates 41.

[0043] Next, the movable plate 19 moves back and forth, with one end of the push rod 43 pressed against the sidewall of the screening housing 14. This allows the movable plate 19 to swing back and forth, securing the push rod 43 horizontally, thereby allowing the push rod 43 to slide within the movable plate 19. This sliding of the push rod 43 within the movable plate 19 drives the movable block 49, guided by the uneven structure on the upper portion of the movable block 49 and contacting one end of the connecting block 42. When one end of the connecting block 42 contacts the protrusion of the movable block 49, it causes the connecting block 42 to swing slightly. This swinging movement compresses the first spring 48, generating an elastic force. When one end of the connecting block 42 contacts the recessed portion of the movable block 49, the elastic force of the first spring 48 causes the connecting block 42 to swing slightly back and forth, returning to its original position. This allows the connecting block 42 and the limiting plate 41 to swing slightly back and forth during the movable plate 19's back-and-forth movement, guided by the uneven structure on the upper portion of the movable block 49 and the elastic force of the first spring 48. The agglomerated plastic particles can be repeatedly squeezed and beaten by the small-amplitude back-and-forth swinging of the connecting block 42 and the limiting plate 41 and the back-and-forth movement of the limiting plate 41, which is beneficial for separating the agglomerated plastic particles and thus improving the screening effect.

[0044] Then, the movable plate 19 swings back and forth, driving the plurality of rotating shafts 21 and the brush blocks 22 to move back and forth. The plurality of brush blocks 22 move back and forth to clean the impurities adsorbed on the surface of the plastic particles. The movable plate 19 moves downward, driving the plurality of rotating shafts 21 and the brush blocks 22 to move downward, thereby gradually improving the cleaning effect of the brush blocks 22 on the impurities on the surface of the plastic particles, facilitating the rapid removal of impurities and reducing the impact on the quality of the plastic products.

[0045] Meanwhile, the ejector rod 43 slides within the movable plate 19, and the sliding of the ejector rod 43 drives the movement of a number of racks 51. One side of the rack 51 meshes with the outer wall of the gear 23, and the movement of the rack 51 drives the rotation of the gear 23 and the rotating shaft 21. The rotation of the rotating shaft 21 drives the rotation of the brush block 22. The rotation of the rotating shaft 21 generates an elastic force on the torsion spring 24. When the outer wall of the gear 23 disengages from one side of the rack 51, under the elastic force of the torsion spring 24, the rotating shaft 21 and the brush block 22 rotate back to their original positions, so that the rotating shaft 21 and the brush block 22 can rotate back and forth under the meshing action of the rack 51 and the elastic force of the torsion spring 24. By using the back-and-forth rotation of a number of rotating shafts 21 and brush blocks 22 in cooperation with the back-and-forth movement and downward movement of a number of rotating shafts 21 and brush blocks 22, the cleaning effect of the surface impurities of plastic particles can be greatly improved. Smaller plastic particles and impurities fall into the first collection tank 34 through a number of filter holes 15, and the impurities in the first collection tank 34 fall into the first collection box 38 through the second discharge port 36 for storage.

[0046] Finally, the plastic particles after screening are guided by the second guide plate 26 and enter the metering tank 29 through the opening 56. The amount of packaging is controlled according to the amount of plastic particles entering the metering tank 29. When the amount of plastic particles in the metering tank 29 meets the specified amount, the stepping motor 30 starts to drive the rotation of a number of first partition plates 28, and the rotation of a number of first partition plates 28 drives the movement of a number of metering tanks 29, so that a number of metering tanks 29 are sequentially moved to one side of the opening 56 to store plastic particles. And a number of metering tanks 29 rotate and are sequentially moved to one side of the first discharge port 31, so that the plastic particles in the metering tank 29 fall into the second collection tank 35 through the first discharge port 31. The plastic particles in the second collection tank 35 fall into the second collection box 39 through the third discharge port 37. The staff places the packaging cylinder under the packaging pipe 40, and the plastic particles in the second collection box 39 fall into the packaging cylinder through the packaging pipe 40.

[0047] An integrated packaging device for granular plastic products of the present invention, through the first guide plate 16, the screening shell 14, and the steering gear 32, uses two groups of first guide plates 16 to form an S-shaped channel inside the screening shell 14, thereby prolonging the residence time of plastic particles in the screening shell 14; then uses the steering gear 32 to drive the screening shell 14 to swing back and forth within the outer shell 13. By using the back-and-forth swing of the screening shell 14, the plastic particles can stay in the upper part of the screening shell 14 for a long time, increasing the probability of contact between the plastic particles and a number of filter holes 15, thereby improving the screening effect, and using a number of filter holes 15 to screen out smaller plastic particles and impurities.

[0048] An integrated sub-packaging device for granular plastic products of the present invention, through the settings of the movable plate 19 and the limiting plate 41, utilizes the movable plate 19 and the limiting plate 41 to limit the stacked plastic particles, reducing the stacked plastic particles, and utilizes the reciprocating movement of the movable plate 19 and the limiting plate 41 to disperse the stacked plastic particles evenly. Further, through the setting of the fixed block 25, when the movable plate 19 moves towards the fixed block 25, the upper side of one end of the movable plate 19 contacts the inclined surface of one end of the fixed block 25, and the movement of the movable plate 19 is guided by the fixed block 25, so that the movable plate 19 moves downward. The downward movement of the movable plate 19 drives the connecting block 42 and the limiting plate 41 to move downward. The downward movement of the movable plate 19 and the limiting plate 41 gradually reduces the height of the limit on the stacked plastic particles, which is beneficial to reciprocatingly moving and scraping the stacked plastic particles layer by layer evenly, and the downward movement of the limiting plate 41 squeezes and separates the agglomerated plastic particles. Finally, through the settings of the connecting block 42, the first spring 48, the movable block 49, and the ejector rod 43, under the guiding action of the uneven structure on the upper part of the movable block 49 and the elastic force of the first spring 48, during the reciprocating movement of the movable plate 19, the connecting block 42 and the limiting plate 41 can perform small-amplitude reciprocating swings. The small-amplitude reciprocating swings of the connecting block 42 and the limiting plate 41 and the reciprocating movement of the limiting plate 41 can repeatedly squeeze and beat the agglomerated plastic particles, which is beneficial to separating the agglomerated plastic particles, thereby improving the screening effect.

[0049] An integrated sub-packaging device for granular plastic products of the present invention, through the settings of the rotating shaft 21 and the brush block 22, the reciprocating swing of the movable plate 19 drives a plurality of rotating shafts 21 and brush blocks 22 to move back and forth, and the reciprocating movement of the plurality of brush blocks 22 cleans the impurities adsorbed on the surface of the plastic particles. And the downward movement of the movable plate 19 drives a plurality of rotating shafts 21 and brush blocks 22 to move downward, thereby being able to gradually improve the cleaning effect of the brush blocks 22 on the surface impurities of the plastic particles, which is beneficial to quickly cleaning and removing the impurities and reducing the influence on the quality of the plastic products. Further, through the settings of the gear 23, the rack 51, and the torsion spring 24, under the meshing action of the rack 51 and the gear 23 and the elastic force of the torsion spring 24, the rotating shafts 21 and the brush blocks 22 can rotate back and forth. The cooperation of the back-and-forth rotation of the plurality of rotating shafts 21 and brush blocks 22, the back-and-forth movement of the plurality of rotating shafts 21 and brush blocks 22, and the downward movement of the plurality of rotating shafts 21 and brush blocks 22 can greatly improve the cleaning effect on the surface impurities of the plastic particles.
