Description

Technical Field

[0001] This invention relates to the field of ultra-short viscose fiber production technology, specifically to an ultra-short viscose fiber production line and its preparation method. Background Technology

[0002] Ultra-short viscose fiber, also known as viscose staple fiber, is a fiber material obtained by cutting viscose fibers. In its preparation, the viscose fibers are first pretreated, then cut using fiber cutting equipment, and finally washed and dried for storage and use.

[0003] For example, Chinese patent CN1916274A discloses an ultra-short viscose fiber for papermaking and its manufacturing method. The fiber cutting length is 4.8mm–5.2mm, and its specifications are 1.67–5.56 dtex × 5–10mm. Its raw materials and weight percentage content are: 42–45% cellulose fiber and 55–58% water. Desulfurization heating uses a steam jet pump for external circulation heating. The fiber is spun using a nozzle with a total of 54,100 holes, and the guide rod is made of alumina. The production process includes impregnation, pressing, crushing, aging, xanthation, dissolving, filtering, defoaming, filtering again, spinning, two-bath process, drawing, refining, cutting, and packaging.

[0004] However, in existing technologies, when cutting ultra-short viscose fibers, the viscose fibers are usually poured directly onto the conveyor belt, and the fibers are interlaced. During the cutting process, some fibers are parallel to the cutting blade, resulting in some fibers being cut too long, which affects subsequent processing and use. Summary of the Invention

[0005] The purpose of this invention is to provide an ultra-short viscose fiber production line and its preparation method, in order to solve the problem mentioned in the background art that when ultra-short viscose fibers are cut, they are mostly poured directly onto a conveyor belt, and the fibers are interlaced. During the cutting process, some fibers are parallel to the cutting blade, resulting in some fibers being cut too long, which affects subsequent processing and use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultra-short viscose fiber production line, including a winding machine, a sorting frame, a cutting machine, a washing machine, a filter press, and a dryer. The sorting frame includes an assembly base plate, with a vertical pole fixedly connected to the upper end of the assembly base plate. An inner pole is fixedly connected to one side of the vertical pole, and a side frame is provided on the other side of the vertical pole. The lower end of the side frame is fixedly connected to the assembly base plate. A ring hole frame is fixedly connected inside the side frame. The vertical pole is made of metal and has a hollow interior. The outer sleeve and the ring hole frame are both made of plastic. The side frame is made of metal, and the holes in the ring hole frame are rounded to prevent the viscose fiber from being cut. The assembly base plate can be fastened to the ground with bolts to ensure stability during use.

[0007] The cutting machine includes a cutting machine body, an extension frame fixedly connected to one side of the upper end of the cutting machine body, a first conveyor belt at the lower end of the extension frame, and a second conveyor belt at the upper end of the cutting machine body. The first conveyor belt is located above the second conveyor belt, and a limiting sleeve is provided between the first and second conveyor belts. Side fixing frames are fixedly connected to both ends of the limiting sleeve and the cutting machine body. The side of the limiting sleeve away from the cutting machine body has an expansion design, and the end of the limiting sleeve near the wire separator has a rounded design to prevent the viscose fiber from being cut, ensuring the smooth entry of the viscose fiber. The limiting sleeve is made of plastic, making it lighter and reducing replacement costs. The opening height at the other end of the limiting sleeve is greater than the distance between the first and second conveyor belts to ensure friction on the viscose fiber and pull the viscose fiber in.

[0008] Preferably, an outer sleeve is provided on the outer side of the inner rod, and a bearing is installed between the inner annular surface of the outer sleeve and the outer annular surface of the inner rod.

[0009] Preferably, the cleaning machine includes a cleaning cylinder, the upper end of which is fixedly connected to a housing, a connection port is provided on one side of the housing, and a connecting pipe is fixedly connected between the connection port and the discharge port of the cutting machine body, and a control valve is installed inside the connecting pipe.

[0010] Preferably, a fan frame is fixedly connected to the other side of the housing, and a duct fan is installed inside the fan frame.

[0011] Preferably, a filter screen is fixedly connected inside the housing, and one side of the filter screen is designed to be inclined.

[0012] Preferably, a motor frame and a support leg are fixedly connected to the lower end of the outer surface of the cleaning cylinder, a stirring motor is fixedly connected to the middle of the lower end of the motor frame, and a drive shaft is fixedly connected to the output end of the stirring motor.

[0013] Preferably, one end of the drive shaft passes through the lower end of the cleaning cylinder, and an agitator is fixedly connected to the outer surface of the drive shaft, with the agitator located inside the cleaning cylinder.

[0014] Preferably, the lower end of the cleaning cylinder is inclined, a discharge pipe is fixedly connected to the lower middle part of the outer surface of the cleaning cylinder, a valve is installed at one end of the discharge pipe, and a liquid inlet is fixedly connected to the upper middle part of the outer surface of the cleaning cylinder.

[0015] Preferably, a pump is installed at one end of the valve through a pipeline, the output end of the pump is fixedly connected to an assembly pipe, and one end of the assembly pipe is fixedly connected to the feed inlet of the filter press.

[0016] The preparation method of ultra-short viscose fibers includes the following steps:

[0017] S1. The newly produced viscose fiber is wound into a roll by a winding machine, and then the wound viscose fiber is put on the surface of the outer tube.

[0018] S2. Pull out the ends of the viscose fibers and pass them through the holes of the ring frame one by one, so that the fibers placed in front and behind come together.

[0019] S3. Insert the gathered fibers into the limiting sleeve, and transport the fiber filaments into the cutting machine body through the No. 1 and No. 2 conveyor belts to cut the viscose fiber to the required length.

[0020] S4. After the viscose fiber is cut, it forms ultra-short viscose fiber. The ultra-short viscose fiber gathers at the discharge port. The guide fan causes airflow. The airflow enters from the inlet of the cutting machine body and flows out from the guide fan. At this time, the airflow draws the ultra-short viscose fiber into the casing. The ultra-short viscose fiber is blocked by the filter screen and falls into the cleaning cylinder. At the same time, cleaning liquid is injected into the cleaning cylinder. The cleaning liquid enters from the liquid inlet.

[0021] S5. The stirring motor is turned on, driving the drive shaft and stirring blades to rotate, cleaning the ultra-short viscose fibers;

[0022] S6. After cleaning, open the valve and start the pump to inject the cleaned ultra-short viscose fibers along with the cleaning solution into the filter press. The cleaning solution is discharged through the filter press. Then, manually remove the ultra-short viscose fibers and place them in a dryer to dry them. After drying, they can be stored.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this invention, the viscose fiber is wound during production by the combination of a winding machine and a splitter, which facilitates subsequent processing and transportation. The splitter unfolds the viscose fiber, preventing it from being horizontal with the cutting blade, thus ensuring the cutting length and increasing the yield of ultra-short viscose fiber. The limiting sleeve gathers the viscose fiber together, and when new viscose fiber is added, it can also be brought in by other viscose fibers, preventing hands from being caught in the first and second conveyor belts, thereby increasing production safety.

[0025] 2. In this invention, the ultra-short viscose fibers are collected by airflow through the washing machine, which reduces waste and improves efficiency. The stirring motor is positioned at the bottom to avoid conflict with the exhaust fan. By using multiple washing machines, viscose fiber production can be continuous. During production, when one washing machine is full of viscose fibers, its connected control valve and exhaust fan are closed, while another washing machine is turned on for continuous production. After one washing machine finishes cleaning the ultra-short viscose fibers, the cleaning solution is pumped into a filter press to remove the cleaning solution from the fibers. This method can greatly increase production capacity. Attached Figure Description
