Description

Technical Field

[0001] This utility model relates to the field of PET material processing technology, and in particular to a grinding vibrating screen for PET material. Background Technology

[0002] PET, or polyethylene terephthalate, is a common thermoplastic polyester. It is made from terephthalic acid (PTA) or dimethyl terephthalate (DMT) through a polycondensation reaction with ethylene glycol (EG). It has wide applications in both industrial and everyday life. In modern industrial production, PET materials, due to their excellent mechanical properties, chemical stability, and good processability, are widely used in packaging, textiles, and electronics. For example, in the packaging industry, PET is commonly used to make beverage bottles and food packaging boxes; in the textile industry, PET fibers are an important raw material for synthetic fibers.

[0003] Before being put into practical applications, PET materials often need to undergo a series of processing steps, among which the grinding process is a key step in processing PET raw materials into fine powder that meets specific particle size requirements. The particle size distribution and purity of the ground PET powder directly affect the quality and performance of subsequent products, and the performance of the vibrating screen, as the core equipment for screening and classifying powders in the PET grinding process, is of paramount importance.

[0004] However, in the current process of screening PET materials, when the screen becomes clogged, the clogged screen is cleared by moving it vertically downwards or upwards. The angle and position of the clearing rod cannot be adjusted according to the need for clearing, resulting in incomplete cleaning and the screen holes not being fully restored to unobstructed state, which affects screening efficiency and quality. Utility Model Content

[0005] The purpose of this invention is to provide a grinding vibrating screen for PET materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vibrating screen for grinding PET material includes a mounting frame. The mounting frame is provided with a vibrating screening component that vibrates the PET material. The vibrating screening component vibrates on the mounting frame to screen the PET material. The vibrating screening component is provided with a clearing moving component. The clearing moving component is provided with a clearing angle adjusting component. The clearing angle adjusting component is rotatably connected to the clearing moving component. The clearing angle adjusting component is provided with a blockage clearing component to clear the screen holes.

[0008] A further technical solution is provided, wherein the vibrating screening component includes a mounting frame, a screening screen, a discharge funnel, and four mounting ears. The mounting frame is inclined, and the four mounting ears are located at the four corners of the mounting frame. Each mounting ear has a helical spring at its bottom, and the bottom of the helical spring is connected to the mounting frame. The screening screen is mounted on the mounting frame, the discharge funnel is located at the bottom of the mounting frame, and four vibration motors are provided on the side wall of the mounting frame.

[0009] A further technical solution is that the unblocking moving component includes a movable screw slide, a moving frame, and two electric slides. The two electric slides are symmetrically arranged on the inner side wall of the mounting frame and located above the screening screen. The two ends of the movable screw slide are connected to the moving ends of the two electric slides, and the moving frame is located on the moving ends of the movable screw slide.

[0010] In a further technical solution, the unblocking angle adjustment component includes an adjustment motor and an adjustment seat. The adjustment seat has two rotating shafts at both ends, and the adjustment seat is rotatably connected to the moving frame through the two rotating shafts. The adjustment motor is located on the moving frame, and the main shaft of the adjustment motor is connected to the rotating shafts for transmission.

[0011] In a further technical solution, the blockage-clearing component includes a movable electric cylinder and a clearing rod. The movable electric cylinder is mounted on an adjusting seat, and the clearing rod is connected to the telescopic end of the movable electric cylinder. The clearing rod is covered with a rubber sleeve.

[0012] In a further technical solution, the diameter of the unblocking rod and the rubber sleeve is much smaller than the diameter of the sieve holes on the screening screen.

[0013] In a further technical solution, the blockage clearing component includes a high-pressure jet nozzle and a connecting cylinder. The connecting cylinder is located on an adjusting seat, and the high-pressure jet nozzle is located at the bottom of the adjusting seat and is connected to the connecting cylinder.

[0014] The beneficial effects of this utility model are:

[0015] This utility model's unblocking component works by clearing the screen holes. Adjusting the motor drives the adjusting seat to rotate on the moving frame via two shafts, changing the angle of the unblocking rod. Applying external force from different directions moves the blockage, more thoroughly loosening the adhesion between the blockage and the screen. Blockages generated from PET material grinding may adhere to the screen due to electrostatic adsorption, particle compression, and other factors. Cleaning in a single direction is insufficient to reach all adhesion points. Multi-angle movement breaks down the adhesive structure between the blockages, making it easier for them to detach from the screen holes, restoring unobstructed flow, significantly improving cleaning efficiency, and ensuring the recovery of the screen's screening performance. Furthermore, multi-angle movement disperses the cleaning force, avoiding excessive force in a localized area and reducing damage to the screen. When cleaning PET material blockages, multi-angle movement effectively cleans while protecting the structural integrity of the screen, extending its service life, and reducing production costs.

[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please refer to Figure 1-5 As shown; This utility model provides a technical solution for a grinding vibrating screen for PET materials: A grinding vibrating screen for PET materials includes a mounting frame 1, on which a vibrating screening component 2 is provided to vibrate the PET material. The vibrating screening component 2 vibrates on the mounting frame 1 to screen the PET material. The vibrating screening component 2 is provided with a clearing moving component 3, and the clearing moving component 3 is provided with a clearing angle adjusting component 4. The clearing angle adjusting component 4 is rotatably connected to the clearing moving component 3. The clearing angle adjusting component 4 is provided with a blockage clearing component 5 to clear the screen holes.

[0025] In this embodiment, refer to Figure 2 As shown, the vibrating screen 2 includes a mounting frame 21, a screen plate 22, a discharge funnel 23, and four mounting ears 24. The mounting frame 21 is inclined, and the four mounting ears 24 are located at the four corners of the mounting frame 21. Each mounting ear 24 has a helical spring 25 at its bottom, and the bottom of the helical spring 25 is connected to the mounting frame 1. The screen plate 22 is mounted on the mounting frame 21, the discharge funnel 23 is located at the bottom of the mounting frame 21, and four vibrating motors 26 are mounted on the side wall of the mounting frame 21.

[0026] After the PET material is placed on the screening screen 22, the four vibrating motors 26 will drive the mounting frame 21 to vibrate on the mounting frame 1 through the four helical springs 25. This causes the PET material to be vibrated and screened on the screening screen 22. PET material that meets the requirements will move downwards from the screening screen 22 for discharge, while PET material that does not meet the requirements and is smaller than the screen holes on the screening screen 22 will fall downwards into the discharge funnel 23. The discharge funnel 23 will discharge the PET material that does not meet the requirements, thus achieving the screening of PET material.

[0027] In this embodiment, refer to Figure 3 As shown, the unblocking moving component 3 includes a movable screw slide 31, a moving frame 32, and two electric slides 33. The two electric slides 33 are symmetrically arranged on the inner side wall of the mounting frame 21 and located above the screening screen plate 22. The two ends of the movable screw slide 31 are connected to the moving ends of the two electric slides 33, and the moving frame 32 is located on the moving end of the movable screw slide 31.

[0028] In this embodiment, refer to Figure 4 As shown, the unblocking angle adjustment component 4 includes an adjustment motor 41 and an adjustment seat 42. The two ends of the adjustment seat 42 are respectively provided with two rotating shafts 43. The adjustment seat 42 is rotatably connected to the moving frame 32 through the two rotating shafts 43. The adjustment motor 41 is located on the moving frame 32 and the main shaft of the adjustment motor 41 is connected to the rotating shafts 43 in a transmission connection.

[0029] When screening PET materials, the sieve holes on the screening screen 22 may become clogged, and the sieve holes need to be cleaned and unblocked.

[0030] Meanwhile, the unblocking component 5 works to clear the screen holes. The adjusting motor 41 drives the adjusting seat 42 to rotate on the moving frame 32 via two rotating shafts 43, changing the angle of the unblocking rod 52. This applies external force from different directions to move the blockage, more comprehensively loosening the adhesion between the blockage and the screen. Blockages generated from PET material grinding may adhere to the screen due to electrostatic adsorption, particle compression, and other factors. Cleaning in a single direction is unlikely to reach all adhesion points. Multi-angle movement breaks down the adhesive structure between the blockages, making it easier for them to detach from the screen holes, restoring unobstructed flow, significantly improving cleaning efficiency, and ensuring the recovery of the screen's screening performance. Furthermore, multi-angle movement disperses the cleaning force, avoiding excessive force in a localized area and reducing damage to the screen. When cleaning PET material blockages, multi-angle movement effectively cleans while protecting the structural integrity of the screen, extending its service life, and reducing production costs.

[0031] During the unblocking process, the two electric sliding tables 33 and the movable screw sliding table 31 will move the position of the unblocking component 5 to unblock the blockages at different positions on the screening screen 22, making the unblocking more comprehensive.

[0032] It should be noted that the clogging of the screen holes is cleaned when the four vibrating motors 26 are stopped. During the screening process, the adjusting seat 42 can be made to be horizontal by adjusting the operation of motor 41. When cleaning the screen holes, the position of the unblocking moving part is moved above the screen holes to clean them.

[0033] Example 1: Refer to Figure 4 As shown,

[0034] In this embodiment, the blockage-clearing component 5 includes a movable electric cylinder 51 and a clearing rod 52. The movable electric cylinder 51 is mounted on the adjusting seat 42, and the clearing rod 52 is connected to the telescopic end of the movable electric cylinder 51. The clearing rod 52 is covered with a rubber sleeve 53. The rubber sleeve 53 can protect the clearing rod 52 and the sieve holes of the screening screen plate 22.

[0035] The operation of the movable electric cylinder 51 drives the unblocking rod 52 to move downward, which can unblock the screen holes on the screening screen plate 22 and clean the blocked PET material downward.

[0036] In this embodiment, the diameters of the unblocking rod 52 and the rubber sleeve 53 are much smaller than the diameter of the sieve holes on the screening mesh plate 22.

[0037] When clearing blockages in the screen mesh 22, the clearing rod 52 can be inserted into the screen holes to remove the blockages.

[0038] Example 2: Refer to Figure 5 As shown,

[0039] In this embodiment, the blockage clearing component 5 includes a high-pressure jet nozzle 54 and a connecting cylinder 55. The connecting cylinder 55 is located on the adjusting seat 42, and the high-pressure jet nozzle 54 is located at the bottom of the adjusting seat 42 and is connected to the connecting cylinder 55.

[0040] It should be noted that when using high-pressure gas to clean clogged PET material, the PET material must be dry.

[0041] An external air pump is connected to the connecting cylinder 55. Gas is delivered to the connecting cylinder 55 and then ejected upwards through the high-pressure nozzle 54. This high-pressure gas impacts the blockage at a high flow rate, quickly dispersing and removing PET particles and impurities clogging the screen holes. Compared to manual cleaning, high-pressure gas can quickly cover the entire screen surface, significantly reducing cleaning time and improving production efficiency. For slightly clogged screens, high-pressure gas cleaning can be completed within minutes, rapidly restoring the screen's screening performance.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
