Technical Field
[0001] The utility model belongs to the technical field of plastic particle feeding equipment, and in particular relates to a PA plastic particle feeding device. Background Art
[0002] PA is nylon plastic, which is tough, strong and wear-resistant. It is often used to make combs, toothbrushes, clothes hooks, fan ribs, mesh bag ropes, fruit packaging bags, etc. It is non-toxic, but cannot be in contact with acids and alkalis for a long time.
[0003] In the prior art, in order to facilitate the classification and collection of plastic particles, an inclined screen with a vibrator is generally configured in the feeding device of the granulator. When the plastic particles produced by the granulator enter the feeding device, the vibrator is operated to fully shake the inclined screen. The inclined screen uses the screen holes thereon to screen plastic particles of different coarseness and fineness, so that small particles of plastic pass through the screen holes and fall to the bottom of the feeding device for collection, while the screened large particles of plastic automatically slide outward due to the slope of the inclined screen, which is convenient for manual collection separately.
[0004] However, in reality, since plastic particles themselves are smooth, the rolling rate of smooth plastic particles is generally faster when they are shaken and screened on the inclined screen, resulting in a shorter screening time for the plastic particles on the screen, which seriously affects the screening degree of the plastic particles.
[0005] Therefore, a PA plastic particle feeding device is needed to solve the problem in the prior art that, due to the smooth characteristics of plastic particles themselves, the rolling rate of smooth plastic particles is generally faster when they are shaken and screened on the inclined screen, resulting in a shorter screening time of the plastic particles on the screen, which seriously affects the screening degree of the plastic particles.

[0010] It is further worth explaining that the driving component also includes an active rod which is laterally rotatably arranged between the inner walls on both sides of the discharge box and a driving motor installed on the side wall of the discharge box, and a driving gear which meshes with the driven gear is tightly sleeved on the rod body of the active rod, and the output shaft of the driving motor rotates to penetrate into the discharge box and is fixedly connected to one end of the active rod.
[0011] It should be further explained that a plurality of guide grooves are vertically arranged in the inner wall of the material blocking plate, guide rods are slidably arranged in the guide grooves, and the bottom ends of the guide rods pass through the material blocking plate and are fixedly connected to the cross frame.
[0012] As a preferred embodiment, the material-digging component includes a dial turning rod transversely arranged in the discharge end of the lower hopper and a rotating cylinder tightly sleeved on the rod body of the dial turning rod, two dial pieces are symmetrically fixed on the cylinder wall of the rotating cylinder, one end of the dial turning rod is rotatably connected to the inner wall of the lower hopper, and the other end of the dial turning rod passes through the lower hopper.

DETAILED DESCRIPTION
[0023] See also Figure 1-4 The utility model provides a PA plastic granule feeding device, comprising a feeding box 1 and a sieve plate obliquely arranged between the inner walls on both sides of the feeding box 1, a vibrator (not shown) is arranged on the sieve plate, a feeding hopper 2 corresponding to the highest end of the sieve plate is connected and fixed to the top of the feeding box 1, and a discharge port 4 corresponding to the lowest end of the sieve plate is opened on one side of the feeding box 1;
[0024] When in use, turn on the vibrator, and the vibrator can continuously shake the sieve plate inside the discharge box 1. When the plastic particles produced by the granulator are manually put into the inner side of the discharge box 1 using the discharge hopper 2, the plastic particles can fall on the shaking sieve plate, and the sieve plate uses the sieve holes thereon to screen plastic particles of different coarseness and fineness, so that small particles of plastic pass through the sieve holes and fall to the bottom of the discharge box 1 for collection, while the large particles of plastic screened out automatically slide out through the discharge port 4 due to the slope of the sieve plate, which is convenient for manual separate collection, thereby achieving the effect of classified collection.
[0025] However, from a practical point of view, since plastic particles themselves have the characteristics of being smooth, and the rolling rate of smooth plastic particles is generally faster when they are shaken and screened on the inclined screen plate, the screening time of plastic particles on the screen plate is shorter, which seriously affects the screening degree of plastic particles;
[0026] In view of this, if Figure 3 As shown, it is worth noting that the sieve plate is composed of three sieve plates 3 distributed at intervals, a material blocking component is arranged between two adjacent sieve plates 3, and a driving component cooperating with the material blocking component is arranged below the sieve plate;
[0027] The material blocking component includes a material blocking plate 7 vertically slidably disposed between two adjacent sieve plates 3 and a cross frame 13 located below the material blocking plate 7 and laterally fixed between the inner walls of both sides of the material box 1, and a guide assembly is disposed between the material box 13 and the material blocking plate 7;
[0028] By setting the material blocking component and the driving component, during the rolling screening of the plastic particles on the sieve plate, the driving component can act on the material blocking plate 7 in the material blocking component to intermittently reciprocate up and down. When the material blocking plate 7 extends upward and moves above the sieve plate 3, the material blocking plate 7 can effectively block the plastic particles, thereby increasing the retention time of the plastic particles on the sieve plate and making the plastic particles screened more thoroughly on the sieve plate.
[0029] Furthermore, if Figure 3 and Figure 4 As shown, it is worth noting that the driving component includes a transmission tooth plate 12 vertically fixed on the side of the material blocking plate 7 and a driven rod 10 rotatably arranged between the inner walls of both sides of the unloading box 1, and a driven gear 11 meshing with the transmission tooth plate 12 is fixedly connected to the rod body of the driven rod 10;
[0030] The driving component also includes an active rod 8 that is laterally rotatably arranged between the inner walls of both sides of the material box 1 and a driving motor 19 installed on the side wall of the material box 1. A driving gear 9 that meshes with a driven gear 11 is tightly sleeved on the rod body of the active rod 8. The output shaft of the driving motor 19 rotates and penetrates into the material box 1 and is fixedly connected to one end of the active rod 8.
[0031] The driving motor 19 is turned on, and the output shaft of the driving motor 19 rotates forward and reverse intermittently. During this period, when the output shaft of the driving motor 19 rotates forward, the active rod 8 carries the active gear 9 to rotate in the same direction and meshes with the driven gear 11. In this way, the driven gear 11 is forced to rotate and meshes with the transmission gear plate 12, and the blocking plate 7 is forced to slide upward and extend to the top of the screen plate 3, thereby intercepting the material;
[0032] On the contrary, when the output shaft of the drive motor 19 rotates in the reverse direction, the driven gear 11 rotates in the reverse direction and meshes with the transmission gear plate 12. In this way, the material blocking plate 7 is forced to slide down between the two screen plates 3, and the material is no longer intercepted, so that the material can slide out along the screen plate normally.
[0033] Furthermore, if Figure 4 As shown, it is worth noting that a plurality of guide grooves 15 are vertically arranged in the inner wall of the material blocking plate 7, and a guide rod 14 is slidably arranged in the guide groove 15, and the bottom end of the guide rod 14 passes through the material blocking plate 7 and is fixedly connected to the cross frame 13;
[0034] Through the arrangement of the guide rod 14 and the guide groove 15, when the material blocking plate 7 slides up and down under force, the material blocking plate 7 can synchronously slide normally along the rod body of the guide rod 14, so that the guide rod 14 can effectively limit the moving trajectory of the material blocking plate 7 and ensure the stability of the material blocking plate 7 during movement.
[0035] Furthermore, if Figure 4 As shown, it is worth noting that a material shifting component is provided in the discharge end of the lower hopper 2;
[0036] The material-pickup component includes a dialing lever 16 transversely arranged in the discharge end of the lower hopper 2 and a rotating cylinder 17 tightly sleeved on the rod body of the dialing lever 16. Two paddles 18 are symmetrically fixed on the cylinder wall of the rotating cylinder 17. One end of the dialing lever 16 is rotatably connected to the inner wall of the lower hopper 2, and the other end of the dialing lever 16 passes through the lower hopper 2.
[0037] By setting the material-moving component, in the process of using the lower hopper 2 to feed materials into the lower material box 1, the turning rod 16 in the material-moving component can rotate continuously, thereby prompting the paddle 18 to move the plastic particles in the discharge end of the lower hopper 2, thereby increasing the fluidity of the plastic particles in the discharge end of the lower hopper 2, preventing the plastic particles from being blocked at the discharge end of the lower hopper 2, and affecting the feeding rate of the plastic particles into the lower material box 1.
[0038] Furthermore, if Figure 1 As shown, it is worth noting that the shaft of the dial lever 16 and the shaft of the output shaft of the driving motor 19 are both fixedly connected with pulleys, and a transmission belt 22 is connected between the two pulleys;
[0039] When the drive motor 19 is turned on and the output shaft of the drive motor 19 is driven to rotate, the output shaft of the drive motor 19 can still use the transmission belt 22 to drive the dial lever 16, and the dial lever 16 is controlled to carry the rotating drum 17 and the paddle 18 inside the lower hopper 2 to rotate and select the material.
[0040] Furthermore, if Figure 2 and Figure 3 As shown, it is worth noting that a second collecting box 6 is arranged at the bottom of the inner side of the material box 1, a taking groove adapted to the second collecting box 6 is opened on the side wall of the material box 1, a splash shield 20 fixedly connected to the side wall of the material box 1 is arranged on the outer side of the discharge port 4, a first collecting box 5 is arranged below the splash shield 20, and two supporting frames 21 fixedly connected to the side wall of the material box 1 are symmetrically attached to the bottom of the first collecting box 5;
[0041] When the screen 3 is continuously shaken to screen the plastic particles, small particles of plastic can directly fall into the inner side of the second collecting box 6 through the sieve holes of the screen 3, while large particles of plastic can fall into the inner side of the first collecting box 5 through the discharge port 4. In this way, the second collecting box 6 and the first collecting box 5 can be used to effectively separate the large and small particles of plastic under stress.
[0042] In summary: through the setting of the material blocking component and the driving component, in the process of rolling and screening of plastic particles on the screen plate, the driving component can act on the material blocking plate 7 in the material blocking component to intermittently reciprocate up and down, and when the material blocking plate 7 extends upward and moves above the screen plate 3, the material blocking plate 7 can effectively block the plastic particles, increase the retention time of the plastic particles on the screen plate, and make the plastic particles screened on the screen plate more thoroughly; through the setting of the material shifting component, in the process of using the lower hopper 2 to feed the lower material box 1, the turning rod 16 in the material shifting component can rotate continuously, thereby prompting the paddle 18 to shift the plastic particles in the discharge end of the lower hopper 2, thereby increasing the fluidity of the plastic particles in the discharge end of the lower hopper 2, and preventing the plastic particles from being blocked at the discharge end of the lower hopper 2, affecting the feeding rate of the plastic particles into the lower material box 1.
