Description

Technical Field

[0001] This application relates to the technical field of textile waste treatment, and in particular to a device for treating polyester-cotton yarn waste. Background Technology

[0002] In the textile industry, a significant amount of waste polyester-cotton yarn is generated during production. Polyester-cotton yarn is a blend of polyester and cotton fibers, possessing a certain degree of toughness and entanglement. Currently, common waste disposal methods either involve direct disposal, leading to resource waste and environmental pollution, or simple crushing. However, directly crushing polyester-cotton yarn waste is problematic because its long fiber structure and entanglement characteristics easily cause the crushing equipment's blades or rollers to become entangled with the waste, affecting normal equipment operation and reducing crushing efficiency. Furthermore, the crushed material has uneven particle size, making it difficult to meet the requirements for subsequent recycling, such as respinning or producing recycled textiles.

[0003] A search revealed that Chinese Patent Publication No. CN221680398U discloses a cotton yarn cutter, which includes a cutting machine body. A first pneumatic cylinder is provided on the crossbeam at the top of the cutting machine body. The lower end of the first pneumatic cylinder is connected to a connecting block through a pneumatic arm. A cutting blade is installed at the lower end of the connecting block. A reinforcing liner is installed on the connecting block, and the reinforcing liner is engaged with the upper end face of the cutting blade.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: In existing technologies, the longer fiber structures in polyester-cotton yarn waste easily entangle the processing equipment during recycling, affecting equipment operation and reducing processing efficiency. This application addresses the problems of long fibers in polyester-cotton yarn waste easily entangled in crushing equipment and uneven crushing by first cutting the fibers into segments and then utilizing a planetary crushing mechanism in conjunction with a material circulation mechanism. This achieves the technical effect of improving crushing efficiency and material particle size uniformity. Utility Model Content

[0005] In order to avoid the entanglement of long fiber structures in polyester-cotton yarn waste, this application provides a polyester-cotton yarn waste treatment device.

[0006] This application provides a polyester-cotton yarn waste treatment device, which adopts the following technical solution: it includes a cutting device and a crushing device. The cutting device can cut the polyester-cotton yarn waste into short segments, and the crushing device can crush the cut polyester-cotton yarn waste. The crushing device includes a vertical tank, which is equipped with a planetary crushing mechanism and a material circulation mechanism. The planetary crushing mechanism includes a first motor fixedly mounted on the vertical tank. The output shaft of the first motor is coaxially fixedly mounted with a sun gear and a planetary carrier.

A gear ring that meshes with multiple planetary gears is coaxially fixedly mounted on the vertical tank. A rotating rod is coaxially fixedly mounted on the lower end face of each planetary gear, and multiple crushing blades are arrayed on the outer wall of the rotating rod. The crushing blades moving through the planetary motion thoroughly crush the polyester-cotton yarn waste.

[0007] Optionally, the material circulation mechanism includes a first rotating cylinder fixedly arranged coaxially with the sun gear; the upper part of the first rotating cylinder has a discharge port and the lower part has a feed port.

[0008] Optionally, a second motor is fixedly installed on the lower end face of the vertical tank, and an impeller is fixedly installed on the output shaft of the second motor. The impeller is located inside the first rotating cylinder and is higher than the feed inlet.

[0009] Optionally, a sealing disc is coaxially rotatably connected inside the vertical tank; the sealing disc is coaxially and fixedly connected to the first rotating cylinder, and the sealing disc is rotatably connected to multiple rotating rods.

[0010] Optionally, the vertical tank is equipped with a feeding funnel, which is connected to the inner cavity of the vertical tank through an opening and closing valve. The opening and closing valve can prevent the polyester-cotton yarn waste in the vertical tank from flowing back into the feeding funnel during crushing.

[0011] Optionally, the cutting device includes a worktable with a conveyor belt; the worktable is provided with a flattening mechanism and a cutting mechanism; the flattening mechanism includes a frame on the conveyor belt, a first cylinder on the frame, a pressing plate at the output end of the first cylinder, and multiple cutting grooves arrayed on the pressing plate.

[0012] Optionally, the cutting mechanism includes a second cylinder mounted on a vertical frame; the output end of the second cylinder is provided with a crossbeam, on which multiple cutters are mounted; each cutter is adapted to a corresponding cutting groove, and the cutter can cut the polyester-cotton yarn waste on the conveyor belt through the cutting groove.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model uses the flattening mechanism and the cutting mechanism of the cutting device to cut long fiber polyester-cotton yarn waste into uniform short segments, destroying its entanglement characteristics, avoiding the waste from entanglement with the blades or rollers during traditional direct crushing, and improving the equipment's operational stability and crushing efficiency.

[0015] 2. This utility model uses a planetary crushing mechanism (sun gear, planet gear, gear ring and crushing blade) of a crushing device to thoroughly crush short-segment waste materials under impact and shearing action through planetary motion, thereby improving crushing efficiency.

[0016] 3. The material circulation mechanism of this utility model generates negative pressure by driving the impeller with the second motor, which sucks in the incompletely crushed waste material at the bottom of the vertical tank through the feed port of the first rotating drum and discharges it from the discharge port, realizing a closed-loop process of "crushing → circulation → re-crushing", ensuring that the waste material is crushed without dead corners, reducing sedimentation and waste, and improving the overall processing efficiency.

[0024] The following is in conjunction with the appendix Figures 1-6This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0025] This application discloses a device for treating waste polyester-cotton yarn. For example... Figure 1 As shown, the device includes a cutting device and a crushing device. The cutting device can cut polyester-cotton yarn waste into short segments, and the crushing device can crush the cut polyester-cotton yarn waste. The crushing device includes a vertical tank 1, which is equipped with a planetary crushing mechanism and a material circulation mechanism. The planetary crushing mechanism includes a first motor 2 fixedly mounted on the vertical tank 1. The output shaft of the first motor 2 is coaxially fixedly mounted with a sun gear 3 and a planet carrier 4. Multiple planet gears 5 that mesh with the sun gear 3 are rotatably connected to the planet carrier 4. A gear ring 6 that meshes with multiple planet gears 5 is coaxially fixedly mounted on the vertical tank 1. A rotating rod 7 is coaxially fixedly mounted on the lower end face of each planet gear 5, and multiple crushing blades 8 are arrayed on the outer wall of the rotating rod 7.

[0026] In this embodiment, the polyester-cotton yarn waste is cut into short segments by the cutting device before being fed into the vertical tank 1 for crushing, thereby preventing the polyester-cotton yarn waste from entangled in the crushing components and causing a decrease in crushing efficiency; the first motor 2 drives multiple planetary gears 5 to drive the corresponding crushing blades 8 to perform planetary motion in the vertical tank 1, thereby making the crushing of the waste more thorough.

[0027] Please see Figure 2 and Figure 3 The material circulation mechanism includes a first rotating cylinder 9 coaxially fixed with the sun gear 3; the upper part of the first rotating cylinder 9 is provided with a discharge port 10 and the lower part is provided with a feed port 11; a second motor 12 is fixedly provided on the lower end face of the vertical tank 1, and an impeller 13 is coaxially fixedly provided on the output shaft of the second motor 12. The impeller 13 is located inside the first rotating cylinder 9 and is higher than the feed port 11.

[0028] In this embodiment, the impeller 13 is driven to rotate by the second motor 12 and generate negative pressure. Under the action of negative pressure, the waste at the bottom of the vertical tank 1 is conveyed upward and discharged through the discharge port 10 at the top of the first rotating cylinder 9. This avoids the waste polyester-cotton yarn from accumulating in the dead corner of the vertical tank 1 and not being able to be crushed.

[0029] Please see Figure 3 A sealing disc 14 is coaxially rotatably connected inside the vertical tank 1; the sealing disc 14 is coaxially fixedly connected to the first rotating cylinder 9, and the sealing disc 14 is rotatably connected to multiple rotating rods 7.

[0030] In this embodiment, the sealing disc 14 is used to prevent the waste polyester-cotton yarn in the vertical tank 1 from flying out and causing air pollution.

[0031] Please see Figure 1 The vertical tank 1 is provided with a feeding funnel 15, which is connected to the inner cavity of the vertical tank 1 through an opening and closing valve 16.

[0032] In this embodiment, when it is necessary to feed material into the vertical tank 1, the waste polyester-cotton yarn is put into the feeding funnel 15 and the opening and closing valve 16 is opened. After the waste polyester-cotton yarn in the feeding funnel 15 has completely entered the vertical tank 1, the opening and closing valve 16 is closed, and then the first motor 2 and the second motor 12 are started in sequence.

[0033] Please see Figure 1 , Figure 5 and Figure 6 The cutting device includes a workbench 18 with a conveyor belt 17; a flattening mechanism and a cutting mechanism are provided on the workbench 18; the flattening mechanism includes a frame 19 on the conveyor belt 17, a first cylinder 20 is provided on the frame 19, a pressing plate 21 is provided at the output end of the first cylinder 20, and a plurality of cutting grooves 22 are arrayed on the pressing plate 21; the cutting mechanism includes a second cylinder 23 on the frame 19; a crossbeam 24 is provided at the output end of the second cylinder 23, and a plurality of cutters 25 are provided on the crossbeam 24; each cutter 25 is adapted to a corresponding cutting groove 22, and the cutter 25 can cut the polyester-cotton yarn waste on the conveyor belt 17 into segments through the cutting groove 22;

[0034] In this embodiment, long sections of polyester-cotton yarn waste are placed on the conveyor belt 17. The first cylinder 20 drives the pressing plate 21 to press down, flattening the polyester-cotton yarn waste for easy cutting. The second cylinder 23 drives the cross frame 24 to move multiple cutters 25 downwards. Each cutter 25 is inserted into the corresponding cutting groove 22 to cut the flattened polyester-cotton yarn waste into sections. The cut polyester-cotton yarn waste is then transferred by the operator to the feeding funnel 15.

[0035] The implementation principle of the polyester / cotton yarn waste treatment device in this application embodiment is as follows:

[0036] Long strips of polyester-cotton yarn waste are placed on the conveyor belt 17 on the workbench 18, and the conveyor belt 17 is started to move it toward the cutting mechanism. When the waste moves to the bottom of the flattening mechanism, the first cylinder 20 drives the pressing plate 21 to descend, using the pressing plate 21 to flatten the stacked waste and prevent the waste from sliding during cutting. At the same time, the cutting groove 22 can ensure the cutting accuracy. After flattening, the second cylinder 23 drives the cross frame 24 and the cutter 25 mounted on it to move downward. The cutter 25 inserts into the flattened waste along the cutting groove 22 to cut the long waste into uniform short segments. The cut short waste is transported to the end by the conveyor belt 17, collected by the operator, and poured into the feeding funnel 15 of the crushing device.

[0037] Open the opening and closing valve 16 of the feeding hopper 15, and the short waste material falls into the vertical tank 1. The first motor 2 starts and drives the sun gear 3 and planetary carrier 4 to rotate. Under the meshing action of the sun gear 3 and the fixed gear ring 6, the planetary gear 5 revolves around the sun gear 3, driving the rotating rod 7 and the crushing blade 8 at the lower end to rotate at high speed. The crushing blade 8 in planetary motion impacts and shears the short polyester-cotton yarn waste material in the vertical tank 1, and initially crushes the short waste material into smaller particles.

[0038] The second motor 12 drives the impeller 13 to rotate, forming a negative pressure airflow inside the first rotating cylinder 9. The waste particles that are not completely crushed at the bottom of the vertical tank 1 are sucked into the cylinder from the feed port 11 of the first rotating cylinder 9 under the action of negative pressure, and are conveyed upward to the discharge port 10 for discharge, and fall back into the crushing area at the top of the vertical tank 1. The waste particles undergo the process of "crushing → circulation → re-crushing" in the vertical tank 1 until they reach the required particle size.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
