Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of discharge structure for modified recycled plastic pellets, and in particular to a discharge structure for preparing modified recycled plastic pellets. Background Technology
[0002] The discharge structure for preparing modified recycled plastic pellets from waste plastics is a key link in the entire preparation system, and it has a significant impact on the quality of the final product and production efficiency.
[0003] Chinese utility model patent with authorization announcement number "CN216329392U" discloses a discharge structure for preparing modified recycled plastic granules from waste plastics. It includes a plastic granulation machine, a processing cylinder, and a discharge port. The processing cylinder is installed on the plastic granulation machine, and a discharge port is located at the lower end of the processing cylinder. A rotating seat is fixed to the outer wall of the discharge port, and a rotating rod is rotatably connected inside the rotating seat. Both ends of the rotating rod are connected to caps via connecting rods, and each cap is equipped with an extrusion assembly. By setting a rotatable cap, the cap can drive the pressing block to quickly form or release the seal at the discharge port. However, the discharge end of this device cannot effectively control the discharge rate. This lack of control may lead to a mismatch between the discharge speed and the downstream process. An excessively fast discharge speed can overload downstream equipment, causing it to be unable to process the material in time and resulting in material accumulation.
[0004] Therefore, we provide a discharge structure for preparing modified recycled plastic pellets from waste plastics. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a discharge structure for the preparation of modified recycled plastic granules from waste plastics. This structure can precisely adjust the discharge rate according to the production speed of upstream plastic modification and the needs of downstream granule processing, ensuring close connection between all stages of the production process and avoiding production stagnation or waiting caused by mismatched discharge rates, thereby significantly improving production efficiency.
[0006] In view of this, the present invention provides a discharge structure for preparing modified recycled plastic granules from waste plastics, including a frame, a processing cylinder mounted on the frame, an auxiliary mechanism at the discharge end of the processing cylinder, the auxiliary mechanism including an adjusting cylinder connected to the discharge end of the processing cylinder, a metering cylinder inside the adjusting cylinder, a plurality of notches on the side wall of the metering cylinder, the plurality of notches being symmetrically arranged along the annulus of the metering cylinder, the diameter of the notches being adapted to the discharge port of the processing cylinder and the discharge port below the adjusting cylinder, the notches being installed inside the adjusting cylinder via a rotating shaft, the rotating shaft being connected to an adjusting motor, the adjusting motor being installed on the side wall of the adjusting cylinder, and a controller being provided on the frame.
[0007] Preferably, the output end of the regulating motor is provided with rotating teeth, and one end of the rotating shaft is provided with a retaining cavity, wherein the rotating teeth at the output end of the regulating motor are fitted into the retaining cavity at one end of the rotating shaft.
[0008] Preferably, the discharge port below the regulating cylinder is connected to the first side box, and the first side box is provided with a sieve plate, which is connected to the vibrator below.
[0009] Preferably, the vibrator has a retaining seat at its upper end, and the screen plate is fitted into the retaining seat of the vibrator and can be installed in a detachable manner with the help of fixing bolts.
[0010] Preferably, a fan is provided on the side of the first side box, and a heat dissipation hole is reserved at the upper end of the first side box.
[0011] Preferably, the lower part of the first side box is connected to the second side box, and a vacuum cleaner is provided on the side of the second side box.
[0012] Preferably, the base of the frame is provided with a receiving frame, which is placed directly in front of the discharge port of the second side box.
[0013] Compared with the prior art, this utility model provides a discharge structure for preparing modified recycled plastic pellets from waste plastics, which has the following beneficial effects:
[0014] This invention features an adjustable cylinder below the processing cylinder. The metering cylinder can be pre-set to dispense the correct amount each time. When the rotating shaft drives the metering cylinder to rotate, plastic granules can only pass through when the notch on the metering cylinder aligns with the discharge port of the processing cylinder. This achieves precise dispensing according to the set amount, avoiding arbitrariness in the dispensing quantity. Furthermore, with the use of an adjustable motor, the rotation speed and angle of the metering cylinder can be easily adjusted according to actual production needs, thereby flexibly controlling the dispensing frequency and the amount dispensed each time to meet the precise dispensing requirements of different production processes and product specifications. This invention also achieves precise power transmission through the interlocking installation of the rotating teeth and the clamping cavity. Each rotation of the rotating teeth accurately drives the rotating shaft to rotate at the corresponding angle, ensuring that the metering cylinder rotates according to the set angle and speed, thus guaranteeing the control accuracy of the dispensing quantity and improving the stability and reliability of the entire dispensing structure. In this invention, since some plastic particles may adhere together during subsequent discharge, a sieve plate is provided in the first side box. The sieve plate is connected to a vibrator, which causes the sieve plate to vibrate. Under the action of vibration, the particles will move relative to each other, thereby breaking the adhesion between them and gradually dispersing the adhered particles into individual particles, which then pass through the sieve plate. This ensures that the particles can be processed in a relatively dispersed state.
[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] Example 1: A discharge structure for preparing modified recycled plastic pellets from waste plastics, such as... Figure 1 - Figure 4As shown, the machine includes a frame 1, on which a processing cylinder 11 is mounted. The discharge end of the processing cylinder 11 is provided with an auxiliary mechanism, which includes an adjusting cylinder 2 connected to the discharge end of the processing cylinder 11. The adjusting cylinder 2 contains a metering cylinder 21. The side wall of the metering cylinder 21 is provided with several sets of notches 22. The several sets of notches 22 are symmetrically arranged along the annulus of the metering cylinder 21. The diameter of the notches 22 is adapted to the discharge port of the processing cylinder 11 and the discharge port below the adjusting cylinder 2. The notches 22 are installed in the adjusting cylinder 2 through a rotating shaft 23. The rotating shaft 23 is connected to an adjusting motor 24, which is installed on the side wall of the adjusting cylinder 2.
[0024] In use, after processing is completed, the controller 12 starts the regulating motor 24, which drives the rotating shaft 23 to rotate, thereby causing the metering cylinder 21 to rotate inside the regulating cylinder 2. Since the notches 22 are symmetrically arranged along the annulus of the metering cylinder 21, during rotation, the notches 22 will sequentially align with the discharge port of the processing cylinder 11. When the notches 22 are aligned with the discharge port of the processing cylinder 11, the material inside the processing cylinder 11 falls into the notches 22 by gravity or internal pressure. Due to the notches, the diameter of 22 is adapted to the discharge port of the processing cylinder 11 and the discharge port below the regulating cylinder 2. Therefore, the material can pass through smoothly. As the metering cylinder 21 continues to rotate, when the groove 22 rotates to align with the discharge port below the regulating cylinder 2, the material in the groove 22 is discharged from the discharge port below the regulating cylinder 2, completing one metering discharge process. This cycle continues to perform metering discharge operations. At the same time, with the use of the regulating motor 24, the rotation speed and angle of the metering cylinder 21 can be easily adjusted according to actual production needs, thereby flexibly controlling the frequency of discharge and the amount of discharge each time, meeting the precise requirements of different production processes and product specifications for the amount of discharge.
[0025] like Figure 1 - Figure 4 As shown, the output end of the regulating motor 24 is provided with a rotating tooth 25, and one end of the rotating shaft 23 is provided with a retaining cavity. The rotating tooth 25 at the output end of the regulating motor 24 and the retaining cavity at one end of the rotating shaft 23 are fitted together. In use, the fitting of the rotating tooth 25 and the retaining cavity can achieve relatively precise power transmission. Each rotation of the rotating tooth 25 can accurately drive the rotating shaft 23 to rotate at the corresponding angle, ensuring that the metering cylinder 21 rotates according to the set angle and speed, thereby ensuring the control accuracy of the output amount and improving the stability and reliability of the entire discharge structure.
[0026] like Figure 1 - Figure 4As shown, the discharge port below the regulating cylinder 2 is connected to the first side box 3. The first side box 3 is equipped with a screen plate 31, which is connected to the vibrator 32 below. Since some plastic particles will adhere together during subsequent discharge, the screen plate 31 in the first side box 3, which is connected to the vibrator 32, causes the screen plate 31 to vibrate. Under the action of vibration, the particles will move relative to each other, thereby breaking the adhesion between them and causing the adhered particles to gradually disperse into individual particles, which then pass through the screen plate 31, thus ensuring that the particles can be processed in a relatively dispersed state.
[0027] like Figure 1 - Figure 4 As shown, the vibrator 32 has a retainer 33 at its upper end, and the screen plate 31 is fitted into the retainer 33 of the vibrator 32 and can be installed in a detachable manner with the help of the fixing bolt 34.
[0028] like Figure 1 - Figure 4 As shown, a fan 35 is provided on the side of the first side box 3, and a heat dissipation hole 36 is reserved at the upper end of the first side box 3. Since the plastic particles will retain heat during the front-end processing, and when the plastic particles vibrate on the sieve plate 31, heat will be generated between the particles and between the particles and the sieve plate 31 due to friction. The fan 35 can accelerate the air flow and exhaust this heat from the heat dissipation hole 36 to the outside of the box, so as to avoid the heat accumulation causing the plastic particles to become too hot.
[0029] like Figure 1 - Figure 4 As shown, the first side box 3 is connected to the second side box 4 at the bottom. A vacuum cleaner 41 is installed on the side of the second side box 4. During use, some light impurities such as dust and fine fibers will be generated during the screening of plastic particles. By using the vacuum cleaner 41, these light impurities that fall from the first side box 3 into the second side box 4 can be collected, preventing impurities from flying around the equipment, keeping the working environment clean, and preventing impurities from being mixed back into the plastic particles, which would affect product quality.
[0030] like Figure 1 - Figure 4 As shown, a receiving frame 5 is provided on the base of the frame 1. The receiving frame 5 is placed directly in front of the discharge port of the second side box 4. After screening by the first side box 3 and further processing or conveying by the second side box 4, materials such as plastic granules are discharged from the discharge port of the second side box 4. The receiving frame 5 can accurately receive these materials and collect them in a specific space for convenient subsequent unified processing.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
