Description

Technical Field

[0001] This utility model relates to the technical field of textile waste treatment equipment, specifically a textile waste crushing equipment for polyester fabric. Background Technology

[0002] Crushing equipment is a machine that breaks solid materials into smaller particles or powders through extrusion, impact, grinding, and other actions. It is widely used in mining, chemical, food, and pharmaceutical fields to meet material processing needs. When using crushing equipment for polyester textile waste, the waste is decomposed into fine fibers or particles through shearing, crushing, and grinding, which helps to recycle and reuse the waste and is suitable for textile recycling, filling material processing and other scenarios.

[0003] A search revealed Chinese patent (CN218872445U), which includes a crushing chamber and a recycling shell. The crushing chamber is connected to the recycling shell, and a baffle is provided at the connection point. Two sets of symmetrically arranged buffer plates are fixed inside the crushing chamber. A crushing structure is located below the two sets of buffer plates, and two sets of symmetrically arranged discharge ports are located below the crushing structure. A recycling drawer is located below the discharge ports, and a collection box is located below the recycling drawer. A crushing component is installed inside the recycling shell, and a feed inlet for discharging waste is opened at the top of the recycling shell. An inlet is also opened at the top of the crushing chamber. The crushing component can initially crush the textile waste fed into the recycling shell through the feed inlet, and the crushing structure performs secondary crushing of the waste, thereby improving the crushing effect. A filter plate can screen out incompletely crushed textile waste, avoiding the impact of incomplete crushing on subsequent processes.

[0004] The aforementioned patent proposes using a crushing component to initially crush textile waste fed into the recycling shell through the inlet, which then falls into the crushing chamber for secondary crushing via the crushing structure. Multiple crushing operations can improve the crushing effect of the waste. The crushed waste then falls into the recycling drawer through the outlet. However, it lacks consideration for the stable entry and flattening of the waste during the feeding stage, which affects the crushing effect, and it does not fully consider the impact of the particle size of the output on subsequent processes.

[0005] Therefore, we propose a textile waste crushing device for polyester fabric that can stably input and fully flatten the waste material for pretreatment and screen the output particles. Utility Model Content

[0006] One of the technical problems this application aims to solve is that the stable entry of waste material and the pre-treatment of flattening during the feeding stage affect the crushing effect, and the impact of the particle size of the output material on subsequent processes is not fully considered.

[0008] In some embodiments, the feeding assembly includes a feeding guide plate, a feeding guide plate is provided on the top front side of the crushing box, two rotating shafts are rotatably connected to the inner side of the crushing box, a servo motor is provided on the right side of the rotating shaft, a pressure roller is provided on the outside of the rotating shaft, a drive pulley is provided on the left side of the rotating shaft, and a connecting belt is sleeved on the outside of the drive pulley.

[0009] In some embodiments, the crushing assembly includes a rotating column a, the outside of which is rotatably connected to the inside of the crushing chamber, and a driven pulley is provided on the left side of the rotating column a, the outside of which is sleeved on the inside of the connecting belt.

[0011] In some embodiments, the bottom of the crushing roller is provided with two inclined plates, the outer sides of the two inclined plates are provided on the inner side of the crushing box, the bottom of the two inclined plates is provided with two crushing rollers, and the outer sides of the two crushing rollers are rotatably connected to the inner side of the crushing box.

[0012] In some embodiments, the screening component includes a guide cone, the outer side of which is disposed at the bottom inner side of the crushing chamber, a fixed frame is disposed at the bottom of the guide cone, a pull-out filter plate is slidably connected to the inner side of the fixed frame, and a handle is disposed at the rear side of the pull-out filter plate.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. The waste material is pre-compressed by the double pressure rollers of the feeding component to prevent material deviation. Then, it is initially sheared by the double crushing rollers and crushing blades of the crushing component, and then crushed by the double crushing rollers below.

[0030] Example 2

[0031] Please see Figures 1-3 The screening component 7 includes a guide cone 71, which is a conical structure that is wider at the top and narrower at the bottom and has a smooth inner wall to reduce waste accumulation. The outer side of the guide cone 71 is set at the bottom of the inner side of the crushing box 1. A fixed frame 72 is set at the bottom of the guide cone 71. The fixed frame 72 is a rectangular metal frame and has a slide rail on the inner side to facilitate the sliding of the pull-out filter plate 74. The pull-out filter plate 74 is slidably connected to the inner side of the fixed frame 72. The pull-out filter plate 74 is a metal plate with filter holes and the diameter of the filter holes can be changed according to the requirements. A handle 76 is set on the rear side of the pull-out filter plate 74. The handle 76 is made of U-shaped plastic and has a non-slip surface to facilitate the operator to pull it out.

[0032] A connecting frame plate 75 is provided on the top of the pull-out filter plate 74. The connecting frame plate 75 is an annular metal plate and is welded perpendicularly to the pull-out filter plate 74 to ensure a seal. The top of the connecting frame plate 75 is in contact with the bottom of the guide cone 71. A sealing strip is provided at the contact point to prevent waste particles from leaking out. The pull-out filter plate 74 is slidably connected to the outside of the crushing chamber 1 in the external groove. Vibration devices 73 are provided on both sides of the outside of the fixed frame 72. The vibration devices 73 are electromagnetic vibrators and the vibration frequency is adjustable to improve the screening efficiency. The outside of the two vibration devices 73 is located inside the crushing chamber 1.

[0033] Based on the above embodiments, the following is the complete working principle of the above embodiments: Polyester textile waste is fed into the equipment through the feed guide plate 31 set on the front side of the top of the crushing box 1. The servo motor 32 in the feeding assembly 3 is started. The servo motor 32 drives the rotating shaft 33 connected to it to rotate. Since the active pulley 35 on the left side of the rotating shaft 33 transmits power through the connecting belt 36, the two rotating shafts 33 rotate synchronously, thereby driving the pressure roller 34 outside the rotating shaft 33 to rotate relative to each other, pre-compressing the fed polyester textile waste to avoid the waste from shifting or becoming loose during the subsequent crushing process, resulting in insufficient crushing. At the same time, it guides the waste to enter the working area of ​​the crushing assembly 4 stably. The active pulley 35 drives the driven pulley 42 on the left side of the rotating column a41 in the crushing assembly 4 to rotate through the connecting belt 36. The rotating column a41 rotates inside the crushing chamber 1. The gear a45 on the right side of the rotating column a41 meshes with the gear b46 on the right side of the rotating column b47, thereby driving the rotating column b47 to rotate synchronously in the opposite direction. The crushing roller 43 outside the rotating column a41 and the rotating column b47 rotate accordingly, cooperating with the multiple crushing blades 44 set inside the crushing chamber 1 to perform preliminary shearing and crushing on the pre-compressed polyester textile waste, crushing large pieces of waste into smaller pieces of material. Under the action of gravity, the material after preliminary crushing falls between the two crushing rollers 6, guided by the two inclined plates 5 set at the bottom of the crushing roller 43 inside the crushing chamber 1. The two crushing rollers 6 rotate relative to each other under the drive of external power, and perform secondary crushing and grinding on the material after preliminary crushing, further reducing the particle size of the material and ensuring that the crushing effect of the material meets the requirements of subsequent processing.

[0034] After secondary crushing, the material falls into the screening component 7 at the bottom of the inner side of the crushing chamber 1. First, guided by the guide cone 71, the material is evenly dispersed onto the pull-out filter plate 74 inside the fixed frame 72. The vibration devices 73 on both sides of the fixed frame 72 are activated, and the vibration force generated by the vibration devices 73 is transmitted to the pull-out filter plate 74, accelerating the screening process on the pull-out filter plate 74. Material that meets the particle size requirements is screened through the filter holes of the pull-out filter plate 74, while material that does not meet the particle size requirements remains on the pull-out filter plate 74. The connecting frame plate 75 contacts the bottom of the guide cone 71, preventing material from leaking out from the gap between the guide cone 71 and the pull-out filter plate 74. When it is necessary to clean up the remaining unqualified material, the pull-out filter plate 74 is pulled out along the outer slide groove of the crushing chamber 1 and the inner side of the fixed frame 72 using the handle 76 on the rear side of the pull-out filter plate 74, thus completing the cleaning and recycling of unqualified material and ensuring the continuous and stable operation of the equipment.
