Description
Technical Field
[0001] This utility model relates to the field of polyester chip production technology, specifically to a PET finished chip filtration and recycling device. Background Technology
[0002] Bottle-grade polyester chips are high-molecular polymers made primarily from purified terephthalic acid and ethylene glycol through direct esterification and solid-phase polycondensation thickening processes. They possess excellent impact toughness and high strength, low gas permeability, and can extend the shelf life of beverages. Their core application is as a raw material for bottled packaging containers, widely used in beverage, edible oil, daily chemical product, and pharmaceutical packaging.
[0003] During the production process, finished bottle-grade PET chips contain a large amount of blemishes and dust before processing. These mixed chips entering the weighing machine will affect the quality of subsequent products and cause losses in manpower, material resources, and financial resources. To address this, we propose a PET finished chip filtration and recycling device. Utility Model Content

[0020] 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.
[0021] This utility model provides an improved PET finished product chip filtration and recycling device. Please refer to [link / reference]. Figures 1-2 The system includes an outer frame 1, with a material transfer mechanism 2 bolted to the upper surfaces of both ends of the outer frame 1. The end face structure of the outer frame 1 is L-shaped, and one material transfer mechanism 2 is provided at each end of the outer frame 1. A reduction motor 201 is provided on one side of the material transfer mechanism 2, and the reduction motor 201 is bolted to the outer wall of the upper side of the outer frame 1. The output shaft of the reduction motor 201 extends through to the inner surface of the outer frame 1. A material transfer hopper 202 is fixed to the output shaft of the reduction motor 201, and the material transfer hopper 202 passes through the inner wall of the upper end of the outer frame 1 through a bearing. The material transfer hopper 202 is rotatably connected to the outer frame 1 through the output shaft of the reduction motor 201. The material transfer hoppers 202 at both ends of the outer frame 1 are used for feeding and discharging materials, which facilitates the slicing and filtering operation.
[0022] Please see Figures 1-3A PET finished product chip filtration and recycling device includes: an inner frame 3 disposed inside the outer frame 1, the inner frame 3 matching the outer frame 1 in shape and structure, and the outer surface of the inner frame 3 not contacting the inner surface of the outer frame 1. The matching but non-contact outer frame 1 and inner frame 3, during actual operation, enclose the inner frame 3 through the outer frame 1, improving operational safety. Furthermore, the non-contact outer frame 1 is less susceptible to the impact of vibration from the inner frame 3, preventing displacement of the outer frame 1 due to vibration or loosening of equipment on the outer frame 1. An anchor plate 4 is fixed to the lower end of the inner frame 3, and the anchor plates 4 are symmetrically arranged about the central axis of the inner frame 3. The anchor plates 4 are used to fix the inner frame 3 to the working surface in the working environment using fasteners, preventing displacement of the inner frame 3 due to vibration. A servo motor 5 is bolted to the outer wall of one side of the upper end of the inner frame 3. A rotating roller 6 is fixed to the output shaft of the servo motor 5, and the rotating roller 6 passes through the upper end of the inner frame 3 via bearings. The inner wall has two rotating rollers 6 located on the upper inner side of the inner frame 3. A screen 7 is wound around the outer wall of the rotating rollers 6, and the screen 7 is rotatably connected to the inner frame 3 via the output shaft of the rotating rollers 6 and the servo motor 5. The screen 7 is used to convey bottle-grade PET finished product chips with blemishes and dust through the drive of the rotating rollers 6. Simultaneously, the vibration of the vibrating motor 8 causes the blemishes and dust to fall onto the distribution plate 9 for easy recycling. Both outer walls of the inner frame 3 are secured with bolts. Equipped with a vibration motor 8, the lower ends of the screen 7 and the rotating roller 6 are provided with an inclined distribution plate 9, which is fixed to the inner surface of the inner frame 3. The rotating hoppers 202 are connected by the screen 7 and the distribution plate 9. The rotating hopper 202 on the upper side of one side of the outer frame 1 is used to put unseparated bottle-grade PET finished product slices onto the screen 7. The rotating hopper 202 on the upper side of the other side of the outer frame 1 is used to collect the scabs and dust that fall off the distribution plate 9 through vibration, which is convenient for recycling.
[0023] Please see Figure 1 and Figure 4A PET finished product chip filtering and recycling device includes: an arc-shaped plate 10 spirally downward connected to the inner surface of the inner frame 3 near the servo motor 5; side baffles 11 fixed to the outer walls of both sides of the arc-shaped plate 10; fixing screw holes 12 provided at the connection between the side baffles 11 and the inner frame 3; and the arc-shaped plate 10 and the inner frame 3 form a detachable structure through the side baffles 11 and the fixing screw holes 12. The detachable arc-shaped plate 10 is easy to remove for cleaning and maintenance. When installed on the inner frame 3, it facilitates the separate recycling of filtered bottle-grade PET finished product chips falling from the screen 7, preventing the filtered bottle-grade PET finished product chips from being mixed with scabs or dust again; and a pulley 13 is embedded in the upper surface of the arc-shaped plate 10 through a rotating shaft. The pulleys 13 are evenly distributed at equal intervals along the upper surface of the arc-shaped plate 10, and the pulleys 13 facilitate the sliding of bottle-grade PET finished product chips falling on the arc-shaped plate 10 from the other side of the arc-shaped plate 10, making it easy to collect these chips stably.
[0024] Working principle: For this type of PET finished product chip filtration and recycling device, firstly, the geared motor 201 drives the rotating hopper 202 to rotate, and the PET chips to be processed are put into the rotating hopper 202 at the upper end of the outer frame 1 on one side. The chips fall onto the surface of the screen 7. The servo motor 5 drives the rotating roller 6 to rotate, so that the screen 7 continuously conveys materials. At the same time, the vibration motor 8 works, so that the screen 7 vibrates, promoting the falling of blemishes and dust from the screen holes. The clean chips after screening move to the end with the screen 7, and are guided out and collected by the arc plate 10 and the pulleys 13 on its surface. The blemishes and dust that are screened off fall onto the inclined distribution plate 9 and are concentrated and slid to the rotating hopper 202 on the other side of the outer frame 1 for discharge and recycling. In the whole process, the inner frame 3 is fixed by the anchor plate 4, the outer frame 1 plays a role in enclosure and support, and the arc plate 10 is detachable for easy cleaning, realizing efficient and continuous filtration and separation.
