Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening machine technology, and in particular to a vibrating screening machine for waste plastic reprocessing. Background Technology
[0002] Vibrating screens for waste plastic reprocessing are key pretreatment equipment in plastic recycling processes. They are mainly used to classify and screen crushed and washed waste plastic fragments according to particle size to remove impurities (such as sand, metal shavings, paper scraps, and excessively fine powders), ensuring the purity and uniformity of raw materials for subsequent granulation or modification processes.
[0003] However, in the existing technology, the screens of most vibrating screens are bolted or welded into the screen box, which is inconvenient for later maintenance. If the material is stuck on the screen and not cleaned in time, it will easily reduce the screening effect. Moreover, after the waste plastic is recycled, the particles are easy to stick together to form large pieces of material, which are not easy to separate by the vibration of the screen, thus reducing the screening efficiency of the material.

After cleaning, the screen is embedded into the inside of the screen box, so that the clamping plate is embedded in the inside of the clamping groove, which can improve the stability of the screen. The sealing cover drives the connecting plate to slide into the U-shaped plate from one side, so that the sealing cover seals the upper end of the screen box to prevent the material from splashing out during screening. The sealing cover can also limit the clamping plate so that it will not shake or slide inside the clamping groove, and more stably drive the screen to be embedded inside the screen box.
[0021] 2. In this utility model, the material falls into the inside of the barrel through the feed inlet. At the same time as feeding, the drive motor is turned on and drives multiple separating blades to rotate through the connecting shaft. The separating blades separate the falling material to prevent the material from sticking together and affecting the screening effect. The dispersed material falls into the inside of the guide hopper through the discharge outlet, and is fed into the feed box through the guide hopper. It then falls onto the screen through the feed box. The vibrating screen is then started to screen the material, which greatly improves the screening effect. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0026] Example 1, such as Figure 1-4 As shown, this utility model provides a vibrating screening machine for waste plastic reprocessing, including: a vibrating screening machine body 1, a mounting frame 103, a disassembly and assembly component, and a separation component; The assembly and disassembly components include: multiple slots 113 are provided on the internal opposite surfaces of the screen box 101, and a card plate 117 is movably embedded in the slot 113. The multiple card plates 117 are divided into two groups, and multiple screens 112 are fixedly installed on the opposite surfaces of the two groups of card plates 117. Among them, the screen 112 can be taken out from the inside of the screen box 101 by the card plate 117. Multiple screens 112 are stacked up and down, and multi-layer screening can improve the screening effect. The detachable screen 112 can be cleaned and maintained regularly to prevent materials from getting stuck in the screen holes and affecting the screening effect. U-shaped plates 120 are fixedly installed on the upper ends of the screen box 101 near the outer surfaces on both sides. The sealing cover 102 drives the connecting plate 115 to move and be embedded inside the U-shaped plate 120. The sealing cover 102 covers the upper end of the screen box 101. In addition, the sealing cover 102 covers the upper end of the screen box 101, which can block the card plate 117 inside the card slot 113, prevent the card plate 117 from sliding out of the inside of the card slot 113, improve the stability of the card plate 117, and make the screen 112 better embedded inside the screen box 101. When the screen 112 needs to be disassembled, the sealing cover 102 can be removed and the screen 112 can be taken out for cleaning.
[0027] In this embodiment, two through holes 116 are provided on one side of the sealing cover 102, and two threaded holes 119 are provided on the side of the screen box 101 near the through holes 116. The bolts 118 are threaded through the through holes 116 and installed inside the threaded holes 119 to position the sealing cover 102 and prevent material from splashing out during screening.
[0028] Example 2, as Figure 1-4 As shown, the separation assembly includes: a barrel 105 is fixedly installed on the top of the mounting frame 103; a drive motor 107 is fixedly installed at the center of one side of the barrel 105; a connecting shaft 108 is fixedly installed through the output end of the drive motor 107 through the barrel 105; multiple separation blades 109 are fixedly installed on the outer surface of the connecting shaft 108; and a feed inlet 106 is opened on the outer surface of the barrel 105. The material to be screened can be added into the barrel 105 through the feed inlet 106. The drive motor 107 drives the connecting shaft 108 to rotate inside the barrel 105. The connecting shaft 108 drives multiple separating blades 109 to stir and disperse the fed material, breaking up the sticky material for easy screening later.
[0029] In this embodiment, a discharge port 110 is provided on the side of the barrel 105 away from the feed inlet 106. A feed box 111 is fixedly installed on one side of the top outer surface of the sealing cover 102. The feed box 111 is connected to the sealing cover 102. A guide hopper 114 is fixedly installed on the outer surface of the feed box 111. The separated material falls into the inside of the guide hopper 114 through the discharge port 110, falls into the feed box 111 through the guide hopper 114, and falls onto the screen 112 inside the screen box 101 for screening. Self-locking casters 104 are fixedly installed at the four corners of the bottom of the mounting frame 103. The barrel 105 can be moved by the self-locking casters 104 so that the discharge port 110 at the bottom of the barrel 105 is aligned with the guide hopper 114, or it can be moved to one side to facilitate the disassembly and assembly of the sealing cover 102 and the screen 112.
[0030] Working principle: When the screen 112 needs to be disassembled, first remove the sealing cover 102, then pull the screen 112 to move the clamping plate 117 out from the inside of the clamping groove 113, so that the screen 112 can be taken out for cleaning and maintenance. After cleaning, embed the screen 112 into the screen box 101, so that the clamping plate 117 is embedded in the inside of the clamping groove 113, which can improve the stability of the screen 112. The sealing cover 102 drives the connecting plate 115 to slide into one side of the U-shaped plate 120, so that the sealing cover 102 seals the upper end of the screen box 101 to prevent the material from splashing out during screening. The sealing cover 102 can also limit the clamping plate 117, so that it will not shake or slide inside the clamping groove 113, and more stably drive the screen 112 to be embedded inside the screen box 101. Material falls into the barrel 105 through the feed inlet 106. At the same time as feeding, the drive motor 107 is turned on and drives multiple separating blades 109 to rotate through the connecting shaft 108. The separating blades 109 separate the falling material to prevent the material from sticking together and affecting the screening effect. The dispersed material falls into the guide hopper 114 through the discharge outlet 110. It is then fed into the feed box 111 through the guide hopper 114 and falls onto the screen 112 through the feed box 111. The vibrating screen 1 starts up and screens the material, greatly improving the screening effect.
