Description

Technical Field

[0001] This utility model relates to the field of plastic pellet production technology, specifically to a plastic pellet sorting device. Background Technology

[0002] A plastic granulator is a plastic granulation equipment. According to the angle between the material flow direction of the extruder head and the screw centerline, the extruder head is divided into an angled extruder head and a right-angle extruder head. The position of the die sleeve can be adjusted by bolts through the support to adjust the relative position of the die sleeve to the die core, so as to adjust the uniformity of the extruded layer thickness. The extruder head is equipped with a heating device and a temperature measuring device. The plastic needs to be cooled and cut after granulation to make plastic granules. However, due to temperature differences, some of the slit plastic granules may stick together after cutting, making them unsuitable for subsequent use. This requires the use of a separate screening device to screen the plastic granules in order to obtain qualified plastic granules, which increases the number of production steps and requires further improvement in the efficiency of obtaining qualified plastic granules. Therefore, we need to propose a plastic granule sorting device. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a plastic particle sorting device, comprising: The machine casing 1 and the multi-stage screening component 5 installed inside the machine casing 1. The upper part of the multi-stage screening component 5 is provided with multiple sets of hot air components 7 for drying plastic particles, and the multi-stage screening component 5 is inclined. The plastic particles in the screening are dried by the hot air components 7. A drive assembly 6 for driving the multi-stage screening assembly 5 is provided on one side of the casing 1. A diversion structure located below the multi-stage screening assembly 5 is installed at the bottom of the inner cavity of the casing 1. The diversion structure is used to classify plastic particles of different specifications.

[0016] The multi-stage screening assembly 5 includes a screen plate 51. The upper surface of the screen plate 51 is provided with a first screen hole area 53, a second screen hole area 54 and a third screen hole area 55 in sequence from the feed end to the discharge end. The upper surface of the screen plate 51 is provided with two sets of reinforcing parts 52 that separate the first screen hole area 53, the second screen hole area 54 and the third screen hole area 55. A fence 56 in the shape of a c is fixedly connected to the outer side of the upper surface of the screen plate 51. In this embodiment, the apertures of the first sieve area 53, the second sieve area 54, and the third sieve area 55 increase sequentially. The first sieve area 53 is used to screen small plastic particles, the second sieve area 54 is used to screen out qualified plastic particles, and the third sieve area 55 is used to screen out adhered plastic particles or uncut plastic particles. This allows for step-by-step screening of plastic particles, achieving preliminary separation of particles of different specifications. The reinforcing part 52 is used to enhance the structural stability of the sieve plate 51 and prevent the sieve plate 51 from deforming during the screening process. The U-shaped fence 56 can prevent particles from leaking out from the side during screening, thereby improving screening efficiency and accuracy.

[0017] The drive assembly 6 includes a motor 61, the output shaft of the motor 61 is driven to a rotating shaft 62, the upper end of the rotating shaft 62 is fixedly connected to an eccentric wheel 63, and a fixing pin 64 is fixedly connected to the upper surface of the eccentric wheel 63. A connecting rod 65 is rotatably mounted on the fixing pin 64, and a bottom shaft 57 for mounting the connecting rod 65 is fixedly connected to one end of the lower surface of the sieve plate 51. Furthermore, the motor 61 drives the fixed pin 64 on the eccentric wheel 63 to rotate, which in turn causes the connecting rod 65 to drive the bottom shaft 57 to move. While the fixed pin 64 moves in a circular motion, the bottom shaft 57 moves in a linear reciprocating motion, thereby driving the screen plate 51 to reciprocate. This enhances the tumbling and moving effect of the particles on the screen plate 51, improves the screening speed and thoroughness, and ensures that the particles can fully pass through the corresponding screen hole area.

[0018] Multiple sets of sliders 16 are fixedly connected to both ends of the lower surface of the sieve plate 51. Multiple sets of guide rails 15 are fixedly connected to both sides of the inner cavity of the machine box 1. The multiple sets of sliders 16 are slidably arranged on the multiple sets of guide rails 15 respectively. A protective cover 3 is provided on one side of the machine box 1. The motor 61 is located on the lower surface of the protective cover 3. Preferably, the cooperation between the slider 16 and the guide rail 15 makes the reciprocating motion of the screen plate 51 more stable, reduces shaking and noise during the screening process, and extends the service life of the device. The protective cover 3 can protect the drive component 6, prevent impurities from affecting the operation of the eccentric wheel 63 and the transmission link 65, and ensure the stable operation of the drive component 6.

[0019] The diversion structure includes a first diversion plate 10, a second diversion plate 11, and a third diversion plate 12 fixed in the inner cavity of the casing 1. The first diversion plate 10, the second diversion plate 11, and the third diversion plate 12 are respectively arranged below the first screen hole area 53, the second screen hole area 54, and the third screen hole area 55. The lower surface of the casing 1 is provided with a bottom groove 13 located at the material discharge end of the first diversion plate 10, the second diversion plate 11, and the third diversion plate 12, and a discharge hopper 14 is installed below each set of bottom grooves 13. In a further preferred embodiment, the first diversion plate 10, the second diversion plate 11, and the third diversion plate 12 in the diversion structure can accurately receive the particles falling from the corresponding first sieve hole area 53, the second sieve hole area 54, and the third sieve hole area 55, and collect particles of different specifications separately through the bottom trough 13 and the discharge hopper 14, thereby realizing the classified collection of particles, avoiding the mixing of particles of different specifications, and improving the convenience of subsequent processing.

[0020] The bottom of the inner cavity of the chassis 1 is fixedly connected to a first partition 8 and a second partition 9 that separate the first diversion plate 10, the second diversion plate 11 and the third diversion plate 12. The first partition 8 and the second partition 9 are respectively located below the two sets of reinforcement parts 52. A delivery pipe 4 is provided at one end of the upper surface of the chassis 1, and a support frame 2 is installed on the lower surface of the chassis 1.

[0021] Secondly, the first partition 8 and the second partition 9 can separate the first diversion plate 10, the second diversion plate 11 and the third diversion plate 12 to prevent particles of different sizes from mixing during the falling process, thereby further ensuring the accuracy of classification, while the dispensing tube 4 facilitates particle dispensing.

[0022] Each of the multiple hot air components 7 includes a hollow plate 72. The hollow plate 72 has multiple heating wires 73 inside, and multiple air outlets 75 are provided on the lower surface of the hollow plate 72. A fan 74 is installed on the upper surface of the hollow plate 72. Vertical plates 71 are provided on both sides of the hollow plate 72 and are fixed to the outside of the casing 1. The air provided by the fan 74 is heated by the heating wires 73 and then blown evenly onto the particles in the sieve through the air outlets 75. This can effectively dry the particles, remove the surface moisture of the particles, and prevent the particles from sticking together due to moisture, which would affect the sieve effect.

[0023] In use, plastic granules are first fed into the multi-stage screening assembly 5 inside the housing 1 through the feeding pipe 4. The motor 61 in the drive assembly 6 is started, which drives the eccentric wheel 63 on the rotating shaft 62 to rotate. The eccentric wheel 63 drives the screen plate 51 through the fixed pin 64 and the connecting rod 65. With the cooperation of the slider 16 and the guide rail 15, the screen plate 51 reciprocates. Since the screen plate 51 is inclined and has a first screen hole area 53, a second screen hole area 54 and a third screen hole area 55, the granules are constantly turned and moved in the reciprocating motion of the screen plate 51. Smaller granules fall onto the first diversion plate through the first screen hole area 53, plastic granules of qualified size fall onto the second diversion plate through the second screen hole area 54, and plastic granules that are stuck together or not completely cut fall onto the third diversion plate through the third screen hole area 55 and are collected through the feed hopper 14 below the bottom trough 13. This realizes the screening and classification of plastic granules and improves the collection efficiency of plastic granules.
