Embodiment 1

[0009] A kind of production method of drawing tube, its production method comprises the following steps:

[0010] Slitting the 180-gram bobbin paper according to the width of the paper tape of 112 mm, taking 22 layers of the above-mentioned slitting paper tapes and immersing them in the glue for coating. After coating, the paper tapes are spirally wound into paper tubes at the same time. After the tube was left to dry for 7 hours, the paper tube was dried in an oven at 50°C for 10 hours until the water content of the paper tube was 5-8%, and then the paper tube was left to stand for 10 hours to cool and balance, and finally According to production needs, the paper tube is cut, finished, polished, and inspected to obtain the finished product.

Embodiment 2

[0012] A kind of production method of drawing tube, its production method comprises the following steps:

[0013] Slitting the 250-gram bobbin paper according to the width of the paper tape of 80mm, taking 15 layers of the above-mentioned slitting paper tapes and immersing them in the glue for coating. After coating, the paper tapes are spirally wound into paper tubes at the same time. After the tube was left to dry for 9 hours, the paper tube was dried in an oven at 60°C for 8 hours until the water content of the paper tube was 6-8%, and then the paper tube was left to stand for 9 hours to cool and balance, and finally According to production needs, the paper tube is cut, finished, polished, and inspected to obtain the finished product.

Embodiment 3

[0015] A kind of production method of drawing tube, its production method comprises the following steps:

[0016] Slitting the 320-gram bobbin paper according to the width of the paper tape is 60mm, taking 12 layers of the above-mentioned slitting paper tapes and immersing them in the glue for coating. After coating, the paper tapes are spirally wound into paper tubes at the same time. After the tube was left to dry for 12 hours, the paper tube was dried in an oven at 80°C for 6 hours until the water content of the paper tube was 8-10%, and then the paper tube was left to stand for 8 hours to cool and balance, and finally According to production needs, the paper tube is cut, finished, polished, and inspected to obtain the finished product.

Abstract

The invention relates to a method for producing an extension pipe, which is characterized in that: the extension pipe is made of a spiral paper tube; and the method for producing the extension pipe comprises the following steps of: splitting 160 to 420 grams of bobbin paper into paper tapes with the width of 35 to 125mm, immersing 6 to 22 layers of the split paper tapes in glue for coating, spirally winding the paper tapes into a paper tube after the coating, standing and air drying the paper tube for 5 to 15 hours, drying the paper tube in a drying oven at the temperature of between 30 and 100 DEG C for 6 to 15 hours until the water content of the paper tube is 6 to 15 mass percent, standing the paper tube for 5 to 10 hours for cooling and balancing, and slitting, finishing, polishing and checking the paper tube according to the requirements of production to obtain a finished product. The extension pipe produced by the method is made of the spiral paper tube; all indexes of the extension pipe reach or exceed the technical indexes of the original irony extension pipe; and the extension pipe has the characteristics of small quality, high strength, low cost, reusability, energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a production method of a drawing tube. Background technique [0002] The drafting tube used in the chemical fiber spinning industry has always been made of iron metal materials in order to achieve the corresponding strength and pressure. Such as Chinese patent, the patent number is " 90213670.4 " a kind of antistatic drafting tube disclosed in the specification, and this drafting tube adopts metal tube body exactly. Making this kind of metal drawing tube not only has relatively high production cost, but also has disadvantages such as easy to rust during use, difficult to reuse, and difficult to transport. Therefore, a new technical solution needs to be produced to solve the above problems. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a production method of a high-strength paper-based metal-substituting drawing tube. [0004] The technical scheme...
