Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving equipment, and specifically to a wool top pretreatment device for cotton spinning. Background Art

[0002] Traditional wool top pretreatment devices usually adopt a horizontal layout, and each functional area such as wool top treatment, treatment agent preparation and wool top storage is unfolded on the same plane. This layout makes the equipment occupy a large area, and it is difficult to efficiently utilize the site resources for a production workshop with limited space. At the same time, due to the relatively scattered functional areas, the energy transfer path inside the equipment is relatively long, and there will inevitably be energy losses during the transfer process, resulting in low energy transfer efficiency, increasing production costs. The wool top pretreatment device of the present application can solve the problems of large floor area and low energy transfer efficiency caused by the unreasonable layout of traditional devices, as well as unstable temperature control affecting the quality of wool top treatment, and thus it is difficult to meet the requirements of modern fine production.

[0003] The defects of existing wool top pretreatment devices are as follows: Patent document CN105088428A discloses a complete set of wool top making equipment with automatic feeding. This document mainly considers the problem that the feeding process is manual feeding, which is not conducive to realizing continuous production, and the fed raw materials are not pre-opened, resulting in unevenness of wool when entering the feeding mechanism. It does not consider the problems of large floor area and low energy transfer efficiency caused by the unreasonable layout of traditional devices, as well as unstable temperature control affecting the quality of wool top treatment, and thus it is difficult to meet the requirements of modern fine production; Patent document CN116103796B discloses a low shrinkage wool top production process. This document mainly considers the problem that a large amount of wastewater needs to be discharged after chemical treatment, which greatly pollutes the environment. It does not consider the problem that due to the lack of multi-dimensional environmental precise monitoring and control means in traditional devices, wool is easily damaged by environmental factors during processing and storage, resulting in waste of raw materials and uneven product quality; Patent document CN114000204B discloses a wool washing and top making process for high sludge and high count wool. This document mainly considers the problems that the wool is not washed cleanly, so the color sense is poor after dyeing, and there is more sewage discharge, which is more troublesome to treat. It does not consider the problem that the rough way of wool top traction and folding in traditional devices leads to chaotic storage of wool tops, which not only increases the difficulty of warehouse management, but also reduces the space utilization rate of the storage warehouse, and is not conducive to large-scale production; Patent document CN100547127C discloses a superfine wool fiber top and its manufacturing method. This document mainly considers how to solve the problems of difficult wool washing and carding due to overly fine wool fibers, and does not consider the problems caused by large frictional resistance of components in traditional equipment, resulting in low operating efficiency and high energy consumption. At the same time, frequent friction also shortens the service life of the equipment and increases the maintenance cost. Summary of the Invention

[0011] Preferably, the surfaces of the ball screw 1, the ball screw 2, the sliding rod 1 and the sliding rod 2 are coated with a self-lubricating coating containing molybdenum disulfide; Position sensors are connected to the nuts of the ball screw 1 and the ball screw 2.

[0012] Preferably, the surface of the traction roller is provided with a wave pattern matching the orientation of the wool fibers; A pressure sensor is installed inside the traction roller, and the pressure sensor is used to traction-monitor the pressure of the roller on the wool strip.

[0013] Preferably, the method of using the wool top pretreatment equipment is as follows: S1, injecting water and treating agent into the treating agent configuration bin through the water inlet and treating agent liquid inlet respectively; S2. Start the four servo motors four installed on the rear wall of the top roll processing bin to drive the roller shaft and the composite roller assembly to operate; S3.

[0014] Preferably, in S2, the following steps are further included: S21. Start the humidity sensor on the inner wall of the top roll processing bin to measure the humidity in the bin and transmit the data to the control system; S22. The servo motor four is powered on to operate, and its output shaft drives the roller shaft to rotate. The roller shaft drives the composite roller assembly to rotate synchronously. The aluminum alloy inner layer provides support, the aerogel thermal insulation layer reduces heat transfer, and the nitrile rubber layer contacts the top roll and provides friction to drive the top roll to move.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By adopting an asymmetric vertical layout in the present invention, the top roll processing bin is placed on the side, and the treatment agent preparation bin and the top roll storage bin are stacked vertically. Compared with the traditional horizontal layout, this layout significantly saves the floor area, is especially suitable for production workshops with limited space, optimizes the space utilization of the factory. At the same time, the energy transfer path is optimized, and the energy transfer efficiency is improved. During the top roll processing, the temperature stability of the roller is crucial. The composite roller assembly of the present invention adopts a design combining an aerogel thermal insulation layer and a nitrile rubber layer. The aerogel thermal insulation layer has an extremely low thermal conductivity of 0.023 W / m·K, and the nitrile rubber layer has a hardness of 60±5 Shore A, effectively blocking external heat interference, achieving a roller surface temperature fluctuation of ≤±0.5°C. A stable temperature environment can ensure that during the top roll processing, the fiber structure of the top roll will not be damaged due to large temperature changes, greatly improving the quality and stability of top roll processing. In contrast, due to poor temperature control of traditional equipment, temperature fluctuations are likely to cause problems such as embrittlement or breakage of the top roll, seriously affecting subsequent processing. Therefore, it can solve the problems of large floor area and low energy transfer efficiency caused by unreasonable layout of traditional equipment, as well as unstable temperature control affecting the quality of top roll processing, and thus it is difficult to meet the requirements of modern fine production.

[0016] 2. By setting up a humidity sensor, an infrared temperature sensor, an environmental gas sensor, and a component sensor, the present invention enables the humidity sensor to monitor the humidity in the top roller processing bin in real time, ensuring a suitable humidity in the processing environment and avoiding quality problems of wool caused by excessive wetness or dryness. The infrared temperature sensor accurately measures the surface temperature of the roller and the temperature of the processing liquid, providing accurate data for temperature control. The environmental gas sensor continuously monitors the concentration of harmful gases and the oxygen content in the top roller storage bin, ensuring the safety of the storage environment. The component sensor detects the content of each component in the processing liquid in the processing agent preparation bin. Based on the data from these sensors, a four-dimensional control model of processing liquid concentration - roller temperature - humidity - storage environment is established. Through this model, the equipment can precisely control the entire top roller processing and storage process, reducing the wool damage rate to 0.8%. This achievement means that more wool raw materials can be converted into high-quality top rollers, improving the utilization rate of wool and significantly enhancing the quality of top roller pretreatment. Therefore, it can solve the problems of traditional equipment, such as the lack of multi-dimensional environmental precise monitoring and control means, which lead to wool being easily damaged by environmental factors during processing and storage, resulting in raw material waste and uneven product quality.

[0017] 3. By installing a top roller traction and folding assembly, the present invention uses ball screw one and ball screw two to form a non-orthogonal planar motion. During the operation of the top roller storage bin, servo motor one drives ball screw one to rotate, and servo motor two drives ball screw two to rotate. The two work together to achieve a complex and precise spatial folding motion. Through this design, the spatial folding trajectory error can be controlled within <0.1 mm, accurately pulling and folding the top roller, enabling the top roller to be neatly and orderly placed in the storage bin. Compared with the rough top roller traction and folding and messy storage of traditional equipment, the present invention greatly improves the regularity of top roller storage. The regular storage method not only facilitates subsequent access and management but also improves the space utilization rate of the storage bin, enabling more top rollers to be stored in a limited space. Therefore, it can solve the problems of traditional equipment, such as the rough top roller traction and folding method, resulting in messy top roller storage, increasing the difficulty of warehouse management and reducing the space utilization rate of the storage bin, which is not conducive to large-scale production.

[0018] 4. In the present invention, a self-lubricating coating containing molybdenum disulfide is coated on the surfaces of ball screw one, ball screw two, sliding rod one, and sliding rod two. Molybdenum disulfide has excellent lubricating properties and can form a lubricating film on the contact surfaces of each component during the operation of the equipment, effectively reducing the frictional resistance between the components. At the same time, the traction roller is designed with a corrugated pattern on its surface that matches the direction of the wool fibers. This corrugated pattern can increase the frictional force between the traction roller and the wool top, and matches the direction of the wool fibers, avoiding damage to the wool fibers, thereby improving the traction effect of the wool top. The reduced frictional resistance makes the equipment operate more smoothly, reduces energy consumption, and improves the operating efficiency of the equipment. Compared with traditional equipment that has low operating efficiency and high energy consumption due to large frictional resistance, the present invention can consume less energy, reduce production costs, and improve the service life and stability of the equipment under the same production tasks. Therefore, it can solve the problems of traditional equipment, such as low operating efficiency and high energy consumption caused by large frictional resistance between components, and the frequent friction also shortens the service life of the equipment and increases maintenance costs.

A composite roller assembly is sleeved on the outer surface of the roller shaft 6, and the composite roller assembly is used to drive the wool top to move in the wool top treatment bin 3 and the wool top storage bin 5; The composite roller assembly includes an aluminum alloy inner layer 7 sleeved on the outer surface of the roller shaft 6, an aerogel thermal insulation layer 8 sleeved on the outer surface of the aluminum alloy inner layer 7, and a nitrile rubber layer 9 sleeved on the outer surface of the aerogel thermal insulation layer 8.

[0028] With its extremely low thermal conductivity of 0.023W / m・K, the aerogel thermal insulation layer 8 effectively blocks external heat interference and reduces heat transfer, making the temperature fluctuation on the roller surface ≤ ±0.5°C, providing a stable temperature environment for wool strip treatment. The nitrile rubber layer 9 has a hardness of 60 ± 5 Shore A. Its surface contacts the wool strips and drives the wool strips to move in the wool strip treatment chamber 3 and the wool storage chamber 5 by its own friction. At the same time, the characteristics of nitrile rubber can also avoid excessive wear on the wool strips.

[0029] The humidity sensor provided on the inner wall of the wool strip treatment chamber 3 continuously monitors the humidity in the chamber to ensure that the humidity of the wool strip treatment environment is appropriate, preventing quality problems of wool due to excessive wetness or dryness.

[0034] The wool top traction and folding assembly includes fixed boxes 16 symmetrically installed on the side walls of the wool top storage bin 5. A servo motor one is installed on the rear wall of the fixed box 16, and the output end of the servo motor one is connected to a ball screw one 17. One end of the ball screw one 17 is connected to the front wall of the fixed box 16 through a shaft part; There are two groups of first sliding rods 18 connected between the front wall and the rear wall of the fixed box 16, and the two groups of first sliding rods 18 are respectively located above and below the first ball screw 17; The outer surfaces of the first ball screw 17 and the two groups of first sliding rods 18 are successively sleeved with a first baffle, a first moving block 19 and a second baffle from front to back. One side of the first moving block 19 is connected with a second servo motor through a connecting piece, the output end of the second servo motor is connected with a second ball screw 20, and one end of the second ball screw 20 is connected to one side of another first moving block 19 through a shaft part; There are two groups of second sliding rods 21 connected between one group of first moving blocks 19 and another group of first moving blocks 19 through shaft parts, and the two groups of second sliding rods 21 are respectively located above and below the second ball screw 20; The outer surfaces of the second ball screw 20 and the two groups of second sliding rods 21 are successively sleeved with a third baffle, a second moving block 22 and a fourth baffle from front to back. The front of the second moving block 22 is connected with a third servo motor through a connecting piece, the output end of the third servo motor is connected with a rotating shaft 23, and a traction roller 24 is sleeved on the outer surface of the rotating shaft 23.

[0035] The surfaces of the first ball screw 17, the second ball screw 20, the first sliding rod 18 and the second sliding rod 21 are coated with a self-lubricating coating containing molybdenum disulfide; Position sensors are connected to the nuts of the first ball screw 17 and the second ball screw 20. The position sensors are used to monitor the positions of the first moving block 19 and the second moving block 22 and feed back the position information to the control system.

[0036] Furthermore, the wool strip traction and folding assembly is installed inside the wool strip storage bin 5 and is used to traction and fold and place the wool strips conveyed from the wool strip processing bin 3. This assembly includes fixed boxes 16 symmetrically installed on the side walls of the wool strip storage bin 5. The first servo motor on the rear wall of the fixed box 16 drives the first ball screw 17 to operate. One end of the first ball screw 17 is connected to the front wall of the fixed box 16 through a shaft part. The two groups of first sliding rods 18 connected between the front wall and the rear wall of the fixed box 16 are respectively located above and below the first ball screw 17, playing an auxiliary guiding role.

[0037] The outer surfaces of the first ball screw 17 and the two groups of first sliding rods 18 are sleeved with a first baffle, a first moving block 19 and a second baffle. The second servo motor connected to one side of the first moving block 19 drives the second ball screw 20 to operate. One end of the second ball screw 20 is connected to one side of another first moving block 19 through a shaft part. There are two groups of second sliding rods 21 connected between one group of first moving blocks 19 and another group of first moving blocks 19 through shaft parts, respectively located above and below the second ball screw 20, also playing a guiding role.

[0038] The outer surfaces of the ball screw 20 and the two sets of sliding rods 21 are sleeved with baffle 3, moving block 22 and baffle 4. The servo motor 3 connected to the front of the moving block 22 drives the rotating shaft 23 to operate. The traction roller 24 sleeved on the outer surface of the rotating shaft 23 is used to pull the wool strips. The self-lubricating coating containing molybdenum disulfide coated on the surface of the ball screw 17, the ball screw 20, the sliding rod 18 and the sliding rod 21 can form a lubricating film on the contact surface of each component during the operation of the equipment, effectively reducing the friction resistance between the components, making the equipment run more smoothly and reducing energy loss.

[0039] The position sensors connected to the nuts of ball screw 17 and ball screw 20 can monitor the positions of moving block 19 and moving block 22 in real time, and feed back the position information to the control system, so as to realize precise control of the pulling and folding action of the wool strip. The wavy pattern matching the direction of wool fibers arranged on the surface of the traction roller 24 can increase the friction between the traction roller 24 and the wool strip, and match the direction of wool fibers to avoid damage to wool fibers and improve the pulling effect of wool strip. The pressure sensor installed inside the traction roller 24 can monitor the pressure of the roller on the wool strip in real time to prevent excessive pressure from damaging the wool strip or too little pressure from causing poor pulling effect.

[0040] See also Figure 6 and Figure 7 , an embodiment provided by the present invention: a wool strip pretreatment device for cotton spinning, wherein the surface of the traction roller 24 is provided with a wavy pattern matching the direction of the wool fiber; A pressure sensor is installed inside the traction roller 24, and the pressure sensor is used for traction monitoring the pressure of the roller on the wool strip.

[0041] Furthermore, the wavy pattern on the surface of the traction roller 24 matches the orientation of the wool fibers, which can increase the friction between the roller and the wool tops, making the wool tops less likely to slip during traction and stably transported. At the same time, because it matches the orientation of the fibers, excessive pulling and damage to the wool fibers during traction is avoided, thereby ensuring the quality of the wool tops.

[0042] The pressure sensor installed inside the traction roller 24 is responsible for real-time monitoring of the pressure of the roller on the wool top. At different stages of wool top pretreatment, the wool top requires different traction pressures. The pressure sensor converts the monitored pressure into an electrical signal and transmits it to the equipment control system. The system is based on the preset pressure range. If the pressure is abnormal, it will regulate the servo motor three connected to the traction roller 24, adjust the roller speed, change the pressure on the wool top, ensure that the traction pressure is always appropriate, and ensure the smooth progress of wool top pretreatment.

[0043] Further, the method of using the wool top pretreatment equipment is as follows: S1. Inject water and treatment agent into the treatment agent preparation bin 4 through the water inlet 10 and the treatment agent inlet 11 respectively; S2. Start the four servo motors IV installed on the rear wall of the top wool treatment bin 3 to drive the roller shaft 6 and the composite roller assembly to operate; S3. Start the water pump 13, pump the treatment liquid prepared in the treatment agent preparation bin 4 through the treatment liquid discharge pipe 12 to the liquid distribution pipe 14, and then evenly spray it above the composite roller assembly by the rotating nozzle 15; S4. The treated top wool enters the top wool storage bin 5.

[0044] Furthermore, in S2, the following steps are also included: S21. Start the humidity sensor on the inner wall of the top wool treatment bin 3, measure the humidity in the bin and transmit the data to the control system; S22. The servo motor IV is energized to operate, its output shaft drives the roller shaft 6 to rotate, the roller shaft 6 drives the composite roller assembly to rotate synchronously, the aluminum alloy inner layer 7 provides support, the aerogel thermal insulation layer 8 reduces heat transfer, and the nitrile rubber layer 9 contacts the top wool and provides frictional force to drive the top wool to move.

[0045] Working principle: In the initial stage of equipment startup, the operator injects appropriate amounts of water and treatment agent into the treatment agent preparation bin 4 through the water inlet 10 and the treatment agent inlet 11 according to the predetermined treatment liquid formula. During the injection process, the flow ratio sensors at the water inlet 10 and the treatment agent inlet 11 monitor the flow rate in real time to ensure that the flow ratio of the two meets the formula requirements, and a suitable treatment liquid is formed by mixing in the treatment agent preparation bin 4. The humidity sensor on the inner wall of the top wool treatment bin 3 is started synchronously when the equipment starts, immediately starts to measure the humidity in the bin, and quickly transmits the measured data to the control system to provide the environmental humidity data basis for subsequent top wool treatment. The four servo motors IV installed on the rear wall of the top wool treatment bin 3 are energized to operate, their output shafts drive the roller shaft 6 to rotate at high speed, and the roller shaft 6 further drives the composite roller assembly to rotate synchronously. The aluminum alloy inner layer 7 provides firm support, the aerogel thermal insulation layer 8 reduces heat transfer, maintains the stability of the roller surface temperature, the nitrile rubber layer 9 contacts the top wool, and drives the top wool to move in the top wool treatment bin 3 by virtue of frictional force, preparing for subsequent treatment liquid spraying treatment. Start the water pump 13. The water pump 13 generates a strong suction force, pumps the treatment liquid that has been prepared in the treatment agent preparation bin 4 through the treatment liquid discharge pipe 12 to the liquid distribution pipe 14. The rotating nozzle 15 connected to the bottom of the liquid distribution pipe 14 rotates at high speed, and evenly sprays the treatment liquid on the top wool above the rotating composite roller assembly below, so that the top wool fully and evenly contacts the treatment liquid, completing the top wool treatment process. At the same time, the infrared temperature sensor at the bottom of the liquid distribution pipe 14 measures the roller surface and treatment liquid temperature in real time to provide data support for temperature control. After being treated by the treatment liquid, the top wool is conveyed from the top wool treatment bin 3 to the top wool storage bin 5 driven by the composite roller assembly. The top wool traction and folding assembly in the top wool storage bin 5 is activated, and the first servo motor, the second servo motor and the third servo motor work together. Through transmission structures such as the first ball screw 17, the second ball screw 20, the first sliding rod 18, and the second sliding rod 21, the movement track and rotation speed of the traction roller 24 are controlled to accurately traction and fold the top wool and place it in the top wool storage bin 5. At the same time, the environmental gas sensor on the inner wall of the top wool storage bin 5 continuously monitors the gas environment in the bin to ensure the safety of the top wool storage environment.
