Description

Technical Field

[0001] This utility model belongs to the field of waste recycling technology for filament composite materials, specifically a modular PET filament composite material waste recycling and processing device. Background Technology

[0002] PET (polyethylene terephthalate) filament composites are widely used in textiles, packaging, and automotive interiors, generating a large amount of scrap and waste products during production and use. To achieve resource recycling and environmental protection, the effective recovery and reprocessing of these waste materials has become an important requirement.

[0003] Currently, the recycling and processing of PET filament composite materials typically involves processes such as sorting, washing, crushing, and melt granulation. Among these, crushing is a crucial pretreatment step that directly affects the efficiency and quality of subsequent processing. Existing recycling and processing equipment often employs a single-level crushing structure in its crushing unit. For PET filament waste that is tough or of uneven size, this can easily lead to incomplete crushing and large particle size differences, resulting in some large pieces of material needing to be returned for reprocessing. This affects the overall processing efficiency and continuity. In addition, the equipment is mostly an integrated structure, making it inconvenient to maintain, clean, or replace core components such as blades and screens, increasing downtime and operational difficulty.

[0004] Therefore, in view of the problems of uneven crushing effect, easy material blockage, and inconvenient equipment maintenance in the existing technology, this utility model proposes a modular PET filament composite material waste recycling and treatment device. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a modular PET filament composite material waste recycling and processing device.

[0007] Preferably, the crushing assembly includes a fixed crushing wheel A and a movable crushing wheel A. The two sides of the fixed crushing wheel A are fixedly connected to the rear side of the inner wall of the upper box, and the two sides of the movable crushing wheel A rotatably penetrate the inner cavity of the upper box. The fixed crushing wheel A and the movable crushing wheel A cooperate with each other.

[0008] Preferably, a drive motor is provided on the right side of the moving crushing wheel A, and the output shaft of the drive motor is fixedly connected to the moving crushing wheel A through a coupling.

[0009] Preferably, the screening screen is inclined, and an L-shaped guide hood is connected to the front side of the upper box cavity and the front side of the screening screen. The lower part of the L-shaped guide hood is connected to a secondary crushing box.

[0010] Preferably, a fixed crushing wheel B is fixedly connected between the two opposite sides of the rear side of the secondary crushing box cavity, and a movable crushing wheel B is rotatably connected to the left side of the front side of the secondary crushing box cavity.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figures 1-6This utility model provides a modular PET filament composite material waste recycling and processing device, including a lower box 1 and an upper box 2 movably connected to the upper part of the lower box 1. During operation, the upper box 2 can be lifted up or moved horizontally to open it in order to thoroughly clean the inside or deal with the fault. A baffle 4 is provided on the top of the upper box 2 through a hinge. The baffle 4 can be opened by pulling the handle 5. This is the main feeding port.

[0029] Furthermore, such as Figure 3 and Figure 4 As shown, a primary crushing assembly 3 is installed above the interior of the upper housing 2. It consists of a fixed crushing wheel A31 and a rotatable moving crushing wheel A32. During operation, the operator feeds PET filament composite material waste into the feeding port. The material first falls into the meshing area between the fixed crushing wheel A31 and the moving crushing wheel A32. The drive motor 6 is started, and the drive motor 6 directly drives the moving crushing wheel A32 to rotate at high speed through the coupling. This generates strong shearing and tearing forces with the fixed crushing wheel A31, which initially crushes large pieces or long strips of waste.

[0030] Furthermore, such as Figure 5 As shown, an inclined screen 8 is installed below the primary crushing component 3. During operation, the material that has undergone primary crushing falls onto the screen 8. Qualified fragments with a size smaller than the mesh size of the screen 8 pass directly through the screen under the action of gravity, fall below and are guided by the feed plate A11, and are finally discharged through the feed hood 12 to enter the next collection or processing process. However, unqualified large particles or materials that have not been fully crushed will slide forward along the screen surface due to the inclination angle of the screen 8.

[0031] Furthermore, such as Figure 4 As shown, a secondary crushing box 10 is connected to the lower front end of the screening screen 8 via an L-shaped guide hood 9. During operation, large particles that have not passed through the screening screen 8 will slide into the L-shaped guide hood 9 and be concentrated and guided into the secondary crushing box 10 below for forced secondary fine crushing.

[0032] Furthermore, such as Figure 4 and Figure 5As shown, the secondary crushing chamber 10 is equipped with a pair of crushing wheels: a fixed fixed crushing wheel B101 and a rotatable moving crushing wheel B102. The power of the moving crushing wheel B102 comes from the moving crushing wheel A32 of the primary crushing. Specifically, a synchronous wheel B105 is fixed to the shaft end of the moving crushing wheel A32, and a synchronous wheel A103 is fixed to the shaft end of the moving crushing wheel B102. The two are connected by a synchronous belt 104. During operation, when the drive motor 6 drives the moving crushing wheel A32 to rotate, the power is transmitted through the synchronous wheel B105, the synchronous belt 104, and the synchronous wheel A103, driving the moving crushing wheel B102 to rotate synchronously in the opposite direction. In this way, the material entering the secondary crushing chamber 10 is further squeezed and sheared between the fixed crushing wheel B101 and the rotating moving crushing wheel B102, and is crushed into smaller particles.

[0033] Furthermore, such as Figure 2 and Figure 4 As shown, a feeding plate B106 is fixed at the bottom of the secondary crushing box 10, and a feeding trough 107 is provided on its front side. At the same time, a feeding plate A11 and a feeding cover 12 are provided in the lower box 1. During operation, the particle size of the material after secondary fine crushing has been significantly reduced. After falling, it is guided by the feeding plate B106 and discharged from the feeding trough 107. It also falls into the lower box 1, where it is mixed with the initially qualified crushed material or collected separately through their respective channels. Finally, it is discharged together or separately from the feeding cover 12.

[0034] Working principle: First, the drive motor 6 starts, driving the moving crushing wheel A32 to rotate. PET filament waste is fed in from the top feeding port and undergoes primary crushing between the fixed crushing wheel A31 and the moving crushing wheel A32. The crushed material falls onto the inclined screening screen 8 for screening. Qualified fine material falls directly into the lower box 1 for collection, while unqualified coarse material slides along the screen into the L-shaped guide hood 9 and enters the secondary crushing box 10. At the same time, the rotational power of the moving crushing wheel A32 drives the moving crushing wheel B102 in the secondary crushing box 10 to rotate synchronously through the synchronous belt 104 transmission mechanism. It works with the fixed crushing wheel B101 to force secondary crushing of the coarse material. The particle size of the material after secondary crushing meets the requirements and is discharged from the discharge chute 107, flowing into the main collection stream. In the whole process, the material achieves automated continuous processing of primary crushing-screening and secondary crushing, without the need for manual intervention to return unqualified materials for reprocessing. In addition, the modular box design makes it very convenient to clean, maintain, and replace the screen or blades inside the equipment, improving the practicality and maintainability of the equipment.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model to be protected.
