Description

Technical Field

[0001] This utility model relates to the technical field of plastic granule processing, and in particular to a plastic granule screening device. Background Technology

[0002] In the production process of screening and bagging plastic granules, traditional plastic granule screening machines face numerous challenges. After screening the plastic granules, existing screening machines require a considerable amount of time to accumulate a sufficient quantity of the screened granules before they can be bagged.

[0003] Meanwhile, operators need to constantly monitor the discharge situation to see if the material meets the discharge capacity. Manually monitoring the discharge situation greatly limits the rational allocation of human resources, and operators cannot take care of other production links, which reduces the overall production efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide a plastic granule screening device. The quantitative discharge device of this device can automatically discharge quantitatively according to a preset schedule. When the material in the storage bin reaches a certain height, that is, close to the appropriate amount for bagging, the discharge process is automatically started. The discharge amount is precisely controlled by the threaded blade shaft, which greatly reduces the time cost of manual judgment and operation, improves bagging efficiency, and avoids errors that may be caused by manual estimation, ensuring the accuracy of the material quantity in each bag.

[0006] To achieve the above objectives, this utility model proposes a plastic granule screening device, comprising:

[0007] The screen box and the base, wherein the screen box includes at least two sets of discharge ports, one of which is located at the bottom of the screen box and the other of which is located on one side of the screen box.

[0008] The screening mechanism is located inside the screen box and includes multiple layers of screens, with the aperture of each layer decreasing from top to bottom. The screens are installed at an angle inside the screen box.

[0009] A vibration system is connected to the screening mechanism. The vibration system includes a vibration motor and a mechanical spring. The screen box is connected to the base via the mechanical spring.

[0010] A quantitative discharging device includes a storage tank with an inlet located below the outlet. Two sets of baffles are rotatably connected inside the storage tank via a shaft. One end of the shaft extends to the outside of the storage tank and is connected to a discharging gear. The two sets of discharging gears mesh with each other. A drive gear is rotatably connected to the outer wall of the storage tank, meshing with one set of discharging gears. A discharging motor is mounted on the outer wall of the storage tank, with its output end connected to the center of the drive gear. A discharging cylinder is located at the outlet of the storage tank, with a threaded blade shaft rotatably connected to its center. A conveying motor is fixed to the outer wall of the storage tank, with its output end connected to one end of the threaded blade shaft. A laser-type level sensor is installed inside the storage tank.

[0011] This utility model discloses a plastic granule screening device. The quantitative discharge device of this device can automatically discharge a fixed amount of material according to a preset schedule. When the material in the storage bin reaches a certain height, that is, close to the appropriate amount for bagging, the discharge process is automatically started. The discharge amount is precisely controlled by the threaded blade shaft, which greatly reduces the time cost of manual judgment and operation, improves bagging efficiency, and avoids errors that may be caused by manual estimation, ensuring the accuracy of the material quantity in each bag.

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The plastic particle screening device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, the plastic granule screening device of this utility model embodiment includes:

[0027] The screen box 1 and the base 2 are provided. The screen box 1 includes at least two sets of discharge ports 3. One discharge port 3 is located at the bottom of the screen box 1, and the other discharge port 3 is located on one side of the screen box 1. The discharge ports 3 at different positions of the at least two discharge ports 3 facilitate the collection and discharge of materials of different particle sizes. The screen box 1 and the base 2 are the basic structure of the equipment. The two cooperate with each other to support the operation of the equipment.

[0028] The screening mechanism is located inside the screen box 1. The screening mechanism includes multiple layers of screens 4, with the aperture of each layer of screens 4 decreasing from top to bottom. The screens 4 are installed at an angle inside the screen box 1.

[0029] The vibration system is connected to the screening mechanism. The vibration system includes a vibration motor 5 and a mechanical spring 6. The screen box 1 and the base 2 are connected by the mechanical spring 6. The vibration generated when the vibration motor 5 is running is transmitted through the mechanical spring 6, which drives the screen box 1 to vibrate, thereby improving the screening efficiency.

[0030] The quantitative discharge device 7 includes a storage tank 8. The inlet of the storage tank 8 is located below the outlet 3. Two sets of baffles 9 are rotatably connected inside the storage tank 8 via a shaft. One end of the shaft extends to the outside of the storage tank 8 and is connected to a discharge gear 10. The two sets of discharge gears 10 mesh with each other. A drive gear 11 is rotatably connected to the outer wall of the storage tank 8. The drive gear 11 meshes with one set of discharge gears 10. A discharge motor is installed on the outer wall of the storage tank 8. The output end of the discharge motor is connected to the center of the drive gear 11. A discharge cylinder 15 is installed at the outlet 3 of the storage tank 8. A threaded blade shaft 12 is rotatably connected to the center of the discharge cylinder 15. A conveyor motor is fixed on the outer wall of the storage tank 8. The output end of the conveyor motor is connected to one end of the threaded blade shaft 12. A laser-type material level sensor is installed inside the storage tank 8. The baffles 9 divide the storage tank 8 into two spaces. The lower space is connected to the discharge cylinder 15.

[0031] Specifically, when the vibrating motor 5 is driven, the vibration generated by the vibrating motor 5 is transmitted to the screen 4 of the screen box 1. The vibration generated by the screen 4 causes the plastic particles to jump and roll continuously on the screen 4, so that particles of different sizes are separated according to the aperture of the screen 4. The plastic particles flow into the interior of the storage box 8 from the discharge port 3. When the height of the plastic particles reaches the preset volume, the height of the plastic particles is fed back by the laser level sensor. The discharge motor is driven to drive the drive gear 11 to rotate. The drive gear 11 drives a set of discharge gears 10 to rotate. The two sets of discharge gears 10 rotate in opposite directions. The baffle 9 opens so that the plastic particles above drive into the space between the storage box 8 and the conveying cylinder. The plastic particles are then conveyed out by the threaded blade shaft 12. The output is conveyed by the threaded blade, so that the plastic particles can be quantitatively discharged. The storage box 8 is used to store the screened particles and to quantitatively discharge them through the discharge cylinder 15. The amount of material is equal for each rotation of the threaded blade. That is, the discharge quantity is determined according to the number of rotations, so as to meet the needs of multiple batches of different quantities of materials.

[0032] In one embodiment of this utility model, such as Figure 2 As shown, the inlet size of the discharge port 3 is larger than the outlet size. The small size of the discharge port 3 allows the material to collect at the outlet position when it leaves, and the discharge port 3 is convenient for mounting and connecting other devices.

[0033] In one embodiment of this utility model, such as Figure 5As shown, it also includes a corrugated folded tube 13. The input end of the corrugated folded tube 13 is connected to the discharge port 3, and the output end of the corrugated folded tube 13 is connected to the inlet of the storage box 8. The corrugated folded tube 13 is used to connect the storage box 8 and the discharge port 3.

[0034] In one embodiment of this utility model, such as Figure 3 As shown, it also includes a discharge head 14. The input end of the discharge head 14 is circular, and the output end of the discharge head 14 is square. The output end of the discharge head 14 is equipped with a discharge sensing sensor. The square discharge port 3 facilitates bagging connection. Since the plastic particles cannot fill the inside of the discharge cylinder 15 when the first batch of plastic particles are removed, the discharge amount is calculated when the first batch of plastic particles are transported from the position of the storage box 8 to the outlet position of the discharge cylinder 15. The discharge amount of the first batch of material is sensed when the discharge sensing sensor senses the discharge.

[0035] In summary, the quantitative discharge device 7 of this equipment can automatically discharge quantitatively according to preset parameters. When the material in the storage bin 8 reaches a certain height, that is, close to the appropriate amount for bagging, the discharge process is automatically started. The discharge amount is precisely controlled by the threaded blade shaft 12, which greatly reduces the time cost of manual judgment and operation, improves bagging efficiency, and avoids errors that may be caused by manual estimation, ensuring the accuracy of the material quantity in each bag.
