Description

Technical Field

[0001] The utility model relates to the technical field of air-jet spinning equipment, in particular to a high-speed spinning cup for air-jet spinning equipment. Background Art

[0002] The air-spinning machine is an advanced spinning equipment that uses airflow to condense and twist the fibers in a high-speed rotating spinning cup and output them into yarn. This technology does not require the use of spindles, but relies on the joint action of multiple components such as the combing roller, the spinning cup, and the false twist device. The combing roller is used to grab and comb the fed cotton fibers, and the centrifugal force generated by its high-speed rotation throws the fibers out. The spinning cup is a small metal cup that rotates more than 10 times faster than the combing roller. The centrifugal action generated discharges the air in the cup to the outside. According to the principle of fluid pressure, the cotton fibers enter the airflow cup and form a fiber flow, which continues to move along the inner wall of the cup. There is a false twist device at the bottom of the spinning cup. When the fiber flow passes through this small hole, yarn is formed.

[0003] The spinning cup, also known as the rotor, is the element that condenses and twists the fibers in rotor spinning. It is shaped like a hollow, thin-walled, truncated cone, with a condensation groove at the maximum inner diameter of the cup's inclined surface. Fibers reaching the cup's inclined surface, driven by the centrifugal force generated by the high surface speed of the cup wall, slide parallel to the inner wall's inclined surface toward the condensation groove, where they form a ring-shaped condensed strand. The rotor, carrying the condensed strand and its connected radial yarn arms, rotates at high speed, achieving twisting and spinning.

[0004] Due to structural reasons, conventional spinning rotors will have attachments on the inner wall surface after long-term use, affecting subsequent processing. Manual cleaning is time-consuming and labor-intensive, while cleaning with chemical reagents will increase maintenance costs and is relatively limited in environmental friendliness.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-speed spinning rotor for air-spinning equipment is proposed. Utility Model Content

[0006] The purpose of the present utility model is to provide a high-speed spinning rotor for air-spinning equipment to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-speed spinning rotor for air-spinning equipment, comprising a spinning rotor and a cleaning frame, wherein the cleaning frame is installed inside the spinning rotor, and the bottom of the cleaning frame is connected to a fixed shaft, and a movable tube is sleeved on the outside of the fixed shaft, and a high-speed bearing is installed on the top of the movable tube, and the cleaning frame comprises a fixed pile, a scraper and a fastening bolt, the scrapers are vertically connected to the left and right sides of the top of the fixed pile, and a fastening bolt is vertically penetrated through the middle of the fixed pile.

[0008] Furthermore, the spinning cup includes a cup body, a condensation groove and an exhaust hole. The middle surface of the inner wall of the cup body is provided with a condensation groove, and the exhaust hole is opened below the inner wall of the cup body.

[0009] Furthermore, the exhaust holes are opened on the surface of the bucket-shaped structure at the lower end of the cup body, and the exhaust holes are arranged in a circular array with the cup body as the center.

[0010] Furthermore, the bottom end of the spinning rotor and the top end of the movable tube are connected to each other by a flange structure, and the bottom surface structure of the spinning rotor and the top surface structure of the movable tube match each other and are connected to each other.

[0011] Furthermore, the fixing piles are fixedly connected to the scraper, and the fastening bolts are arranged in a circular array with the fixing piles as the center.

[0012] Furthermore, the top end of the fixed shaft is connected and fixed to the fixed pile via a fastening bolt, and the fastening bolt and the fixed shaft are threadedly connected.

[0013] Furthermore, the bottom surface structure of the fixed pile and the top surface structure of the fixed shaft are connected to each other in an insert-type structure, and the bottom end of the fixed shaft is fixedly connected to the axis of the high-speed bearing.

[0014] Furthermore, the high-speed bearing is embedded in the bottom end of the movable tube, and the movable tube and the high-speed bearing are fixedly connected, and the fixed shaft is installed in the middle of the movable tube.

[0015] The utility model provides a high-speed spinning rotor for air-spinning equipment, which has the following beneficial effects:

[0016] 1. The utility model installs a cleaning frame inside the spinning cup. When the inner wall of the cup body needs to be cleaned and maintained, it is only necessary to insert the fixing pile into the top surface of the fixed shaft, and then use the fastening bolts to fix the entire cleaning frame to the inside of the spinning cup. By using the above structure, and because the bottom end of the fixed shaft is connected and fixed to the high-speed bearing, when the movable tube is driven by the external driving device and the structural characteristics of the high-speed bearing are used to drive the spinning cup to rotate at high speed, the cleaning frame is relatively stationary inside the spinning cup. Since the scraper fits the inner wall surface of the cup body, the dirt or residual material on the inner wall surface of the cup body can be quickly scraped off, and part of it will fly out from the opening of the cup body, and part of it will be discharged from the inside of the exhaust hole. At the same time, the setting of the exhaust hole can also provide a certain degree of heat dissipation and ventilation to the inside of the rotating cup body, so as to ensure that the cotton fiber will not be affected by the excessively high temperature.

[0017] 2. The utility model connects the movable tube to the bottom end of the spinning rotor through the use of a flange structure, and utilizes the pluggability of the bottom end of the cup body and the surface structure of the top end of the movable tube, so that the two can be quickly docked, and the stability of the connection of the structure after docking can be ensured, and the firmness of the connection between the spinning rotor and the power output end of the driving device can be further ensured. In addition, a group of high-speed bearings are embedded and installed at the bottom end of the movable tube, and the structural characteristics of the high-speed bearings are utilized. Under the traction of the driving device, the spinning rotor connected to it by the movable tube will perform high-speed axial rotation, and the fixed shaft can remain relatively stationary inside the movable tube, so that the cleaning frame connected to the fixed shaft can clean the inside of the spinning rotor. In addition, since the spinning rotor and the cleaning frame have good structural disassembly and assembly with the assistance of the structure of the fixed shaft, the cleaning frame can be structurally disassembled during the operation of the device to achieve normal operation of the spinning rotor and avoid structural interference.

[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figures 1 to 3As shown, a high-speed spinning rotor for air-spinning equipment includes a spinning rotor 1 and a cleaning frame 2. The cleaning frame 2 is installed inside the spinning rotor 1, and the bottom of the cleaning frame 2 is connected to a fixed shaft 3, and the outer portion of the fixed shaft 3 is sleeved with a movable tube 4, and the top of the movable tube 4 is installed with a high-speed bearing 5. The cleaning frame 2 includes a fixed pile 201, a scraper 202 and a fastening bolt 203. The scrapers 202 are vertically connected to the left and right sides of the top of the fixed pile 201, and the fastening bolt 203 vertically penetrates the middle of the fixed pile 201. The fixed pile 201 and the scraper 202 are fixedly connected, and the fastening bolt 203 is fixedly screwed in place. The fixed piles 201 are arranged in a circular array with a center circle, and the top end of the fixed shaft 3 is connected and fixed to the fixed piles 201 by fastening bolts 203, and the fastening bolts 203 are threadedly connected to the fixed shaft 3. When the inner wall of the cup body 101 needs to be cleaned and maintained, it is only necessary to insert the fixed piles 201 into the top surface of the fixed shaft 3, and then use the fastening bolts 203 to fix the entire cleaning frame 2 to the inside of the spinning cup 1. Therefore, when the movable tube 4 is driven by an external driving device, the relatively stationary scraper 202 can quickly scrape off the dirt or residue on the inner wall surface of the cup body 101.

[0024] like Figures 1 to 3 As shown, the spinning cup 1 includes a cup body 101, a condensation groove 102 and an exhaust hole 103. The middle surface of the inner wall of the cup body 101 is provided with a condensation groove 102, and an exhaust hole 103 is provided below the inner wall of the cup body 101. The exhaust hole 103 is provided on the surface of the bucket-shaped structure at the lower end of the cup body 101, and the exhaust holes 103 are arranged in a circular array with the cup body 101 as the center. The bottom end of the spinning cup 1 and the top end of the movable tube 4 are connected to each other by a flange structure, and the bottom surface structure of the spinning cup 1 and the top surface structure of the movable tube 4 match each other and are connected to each other. The bottom surface structure of the fixed pile 201 and the top surface structure of the fixed shaft 3 are connected to each other. The two are connected in a plug-in structure, and the bottom end of the fixed shaft 3 is fixedly connected to the axis of the high-speed bearing 5. The high-speed bearing 5 is embedded in the bottom end of the movable tube 4, and the movable tube 4 and the high-speed bearing 5 are fixedly connected. The fixed shaft 3 is installed in the middle of the movable tube 4. The movable tube 4 is connected to the bottom end of the spinning cup 1 by using a flange structure, and the pluggability of the bottom end of the cup body 101 and the top surface structure of the movable tube 4 is utilized, so that the two can be quickly connected, and the connection stability of the structure after docking can be ensured, and the firmness of the connection between the spinning cup 1 and the power output end of the driving device can be further ensured.

[0025] In summary, if Figures 1 to 3As shown, the air-spinning equipment uses a high-speed spinning rotor. When in use, if it is necessary to quickly remove the attachments on the inner wall surface of the spinning rotor 1, it is only necessary to place the scraper 202 with a certain flexibility inside the cup body 101, and fit the side of the scraper 202 to the inner wall surface of the cup body 101. Then, the fixing pile 201 at the bottom of the scraper 202 is inserted into the top surface of the fixed shaft 3, and then the fastening bolts 203 are used to vertically penetrate the fixing pile 201 and the fixed shaft 3 in sequence, so as to connect and fix the cleaning frame 2 to the fixed shaft 3.

[0026] When the driving device drives the spinning cup 1 to rotate at high speed through the movable tube 4, the cleaning frame 2 will fit into the inner wall surface of the spinning cup 1, so that the cleaning frame 2 can clean the interior, and the processed dust will be discharged through the lower end of the cup body 101 and the exhaust hole 103. During the rotation of the spinning cup 1, due to the use of the high-speed bearing 5, the spinning cup 1 rotates using the high-speed bearing 5 at the bottom of the movable tube 4, so that the cleaning frame 2 installed on the fixed shaft 3 at the top of the high-speed bearing 5 remains relatively stationary, avoiding interference with the rotation of the spinning cup 1.
