Description

Technical Field

[0001] This utility model relates to a surface lint treatment device for polyester-viscose fabric, belonging to the field of polyester-viscose fabric production technology. Background Technology

[0002] Polyester-viscose blended fabric is a blend of polyester and viscose fibers, mainly used to make brushed fabric. Brushed fabric is divided into double-sided brushed fabric and single-sided brushed fabric. Polyester-viscose blended fabric is suitable for making suits, casual wear and women's wear because the finished product has good color, soft texture, smooth hand feel and wool-like texture.

[0003] Utility model patent number 201920954177.3 discloses a polyester-viscose greige fabric based on radiation-resistant fiber polyester-viscose fabric. This polyester-viscose greige fabric includes a fixing plate, four casters, a roller, and a polyester-viscose greige fabric body. The four casters are located at the four corners of the bottom of the fixing plate. The polyester-viscose greige fabric body is wound around the core of the roller. A first vertical plate is connected to the left side of the top of the fixing plate, and a second vertical plate is connected to the right side of the top of the fixing plate. This polyester-viscose greige fabric is based on radiation-resistant fiber polyester-viscose fabric.

[0004] Currently, the production process of polyester-viscose fabric is not fully considered and has the following drawbacks: During the processing of polyester-viscose fabric, lint easily accumulates on the surface of the fabric, and some of the lint is easy to fall off, affecting the quality of the later processing of the polyester-viscose fabric. At present, when processing polyester-viscose fabric, there is a lack of treatment for the lint on the surface of the fabric. Usually, surface treatment is carried out manually, which is time-consuming, labor-intensive, and the treatment effect is not good.

[0005] To solve one of the above problems, there is an urgent need for a surface lint treatment device based on polyester-viscose fabric. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to use the induced draft fan of the air handling equipment to create a slight negative pressure in the internal space of the first roll to remove the surface hair of the polyester-viscose fabric, so as to facilitate the subsequent processing of the polyester-viscose fabric. At the same time, the hair can be effectively collected by the air purification unit. Therefore, a surface hair treatment device based on polyester-viscose fabric is provided.

[0007] The present invention relates to a surface lint treatment device based on polyester-viscose fabric, comprising a U-shaped support frame. The device is characterized by further comprising a first roll and a second roll coaxially and integrally formed with the first roll. The first roll has evenly spaced air inlets. The second roll houses an external rotor motor, which includes an external rotor and a motor shaft located at the center of the external rotor. The external rotor is coaxially arranged with and integrally connected to the second roll. The motor shaft has two connecting ends, respectively connected to one end of a horizontal support rod A and a horizontal support rod B. The other ends of the horizontal support rods A and B are respectively fixedly mounted on two sets of vertical support columns of the U-shaped support frame. A circular retaining ring A, coaxial with the first roll, is fixed on the horizontal support rod A. The first roll is sleeved outside the circular retaining ring A. A circular retaining ring B, coaxial with the second roll, is fixed on the horizontal support rod B. The second roll is sleeved outside the circular retaining ring B. An air outlet is provided on the circular retaining ring A, and the air outlet is connected to an external air treatment device.

[0008] The air outlet is connected to an external air treatment device. The external rotor motor can drive the first roll to rotate around the center line of the horizontal support rod A. The circular retaining ring A is fixed in position relative to the horizontal support rod A. After the air treatment device is turned on, the induced draft fan of the air treatment device creates a slight negative pressure in the internal space of the first roll. Air outside the first roll can enter the first roll through the air inlet and then enter the air treatment device through the air outlet. The polyester-viscose fabric wraps around the outer wall of the first roll. The lint on one side of the polyester-viscose fabric can enter the first roll with the air through the air inlet and then enter the air treatment device through the air outlet. The air containing lint is treated by the air treatment device and then discharged into the atmosphere.

[0009] Preferably, the air handling device includes an air purification unit. The air inlet of the air purification unit is connected to the air outlet via an exhaust pipe, and the air outlet of the air purification unit is connected to an exhaust fan. After the exhaust fan is turned on, the exhaust fan draws air in, creating a slight negative pressure in the internal space of the first roll. Air outside the first roll can enter the first roll through the air inlet, and then enter the air purification unit through the air outlet. The air containing impurities and hair is purified by the air purification unit and finally discharged into the atmosphere by the exhaust fan.

[0010] Preferably, the air purification unit includes a housing with an air filter inside. Both ends of the housing are respectively provided with pipe interfaces A and B for connecting to an exhaust fan and an exhaust duct. Both the air purification unit and the exhaust fan are existing structures, ensuring reliable and convenient connection.

[0011] Preferably, the outer diameter of the circular retaining ring A is slightly smaller than the inner diameter of the first drum 1, with a radius difference of 0.1-1 mm. The circular retaining ring A has an inner hole A that mates with the outer wall of the horizontal support rod A. The outer diameter of the circular retaining ring B is slightly smaller than the inner diameter of the second drum, with a radius difference of 0.1-1 mm. The circular retaining ring B has an inner hole B that mates with the outer wall of the horizontal support rod B. The circular retaining rings A and B do not rotate with the first and second drums, ensuring that a negative pressure or a slight negative pressure can be formed inside the first drum without interfering with the rotation of the first and second drums, thus ensuring the normal operation of the device.

[0012] Preferably, the circular retaining ring A is made of stainless steel or wear-resistant engineering plastic; the circular retaining ring B is also made of stainless steel or wear-resistant engineering plastic. The structure is simple, reasonable, and easy to manufacture.

[0013] Preferably, multiple sets of scraper units are installed on the horizontal support rod A, and the multiple sets of scraper units are arranged around the center line of the horizontal support rod A.

[0014] If the long hairs on the surface of the polyester-viscose fabric cannot be detached from the fabric and have been sucked into the air inlet on the first roll, the first roll can be cut off by the scraper unit as it rotates relative to the scraper unit. The cut-off hairs, along with the other stray hairs that have entered the first roll, are then processed by the air purification unit.

[0015] Preferably, the scraper unit includes a scraper bracket fixed to a horizontal support rod A, the other end of which is fixedly connected to the scraper body, and the cutting edge of the scraper body is attached to the inner wall of the first drum. The structure is simple, reasonable, and easy to manufacture.

[0016] Preferably, the end of the horizontal support rod B is provided with an end fixing plate, which is fixedly connected to the vertical support column of the U-shaped bracket by connecting bolts. This enables quick installation and disassembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention relates to a surface lint removal device for polyester-viscose fabric. The air handling unit's induced draft fan creates a slight negative pressure inside the first roll. Air from outside the first roll enters through the air inlet and then through the air outlet into the air handling unit. The polyester-viscose fabric wraps around the outer wall of the first roll. Lint on one side of the fabric enters the first roll with the air through the air inlet and then through the air outlet into the air handling unit. The air containing lint is treated by the air handling unit and then discharged into the atmosphere, thus removing lint from the surface of the polyester-viscose fabric and facilitating subsequent processing. Simultaneously, the lint is effectively collected by the air purification unit.

[0019] The surface lint treatment device based on polyester-viscose fabric of this utility model has circular retaining rings A and B that do not rotate with the first and second rolls. This ensures that a negative pressure or a slight negative pressure can be formed inside the first roll, without interfering with the rotation of the first and second rolls, thus ensuring the normal operation of the device.

[0020] The present invention describes a surface lint treatment device based on polyester-viscose fabric. If long hairs on the surface of the polyester-viscose fabric cannot be separated from the fabric and have been sucked into the air inlet on the first roll, the first roll rotates relative to the scraper unit, and the scraper unit can cut off the long hairs. The cut-off long hairs, along with the remaining lint entering the first roll, are then processed by an air purification unit. Attached Figure Description
