Description

Technical Field

[0001] The utility model relates to the technical field of producing ultra-high molecular weight polyethylene fibers, in particular to an ultra-high molecular weight polyethylene fiber six-roller machine. Background Art

[0002] High-strength and high-modulus polyethylene fiber is the third generation of high-performance fiber after carbon fiber and aramid. It is the fiber with the highest strength among the fibers that have been industrially produced. However, the production cost of the high-strength and high-modulus polyethylene fiber production line is high, the equipment energy consumption is high, and the output is low, which has seriously hindered the development of the high-performance industry. In the production line of high-performance fibers, the fibers carry a considerable amount of solvent after coming out of the cooling water tank. If they directly enter the subsequent drying and drawing equipment, the requirements for the subsequent equipment are high, and the design cost is often increased a lot. Before entering the drying, they are pre-washed and drawn to wash away part of the solvent, which can reduce the pressure on the subsequent equipment. A new six-roller machine needs to be designed to meet the new process production requirements. Utility Model Content

The upper box is installed at the upper end of the frame, and the heating tank is installed at the bottom middle position of the upper box; two sets of transmission rollers are arranged on both sides of the upper box in an upper and lower two-type pattern, and each transmission roller is driven by gear transmission; a free roller is installed in the middle position of the upper box.

[0005] The upper box body and the heating tank are both made of stainless steel plates, and inlets and outlets are arranged on the left and right sides of the upper box body.

[0006] A group of three transmission rollers are arranged on the left and right sides of the upper box body. The three rollers can stretch the fiber steadily. The two groups of three-roller mechanisms can adjust the stretching multiple. A pressure roller is installed above the top transmission roller. The pressure roller is raised and lowered by a cylinder to prevent the fiber from slipping.

[0007] The transmission rollers are all installed on the upper box body in a two-point type, and are driven by gear meshing at the rear end.

[0008] The free roller can be extended into the bottom of the heating tank through the cylinder, and guide rails are arranged at both ends of the heating tank, so that the free roller can be lifted and lowered smoothly.

[0009] A coil is arranged in the heating tank, and the coil is S-shaped and installed on the inner wall of the heating tank. The coil is provided with an inlet and outlet interface to connect to an external heating source for cyclic heating.

[0010] The bottom of the rack is provided with foot screws, which can adjust the height of the equipment.

[0011] The six-roller machine using the above technical solution has a novel structure, strong safety and reliability, and stable fiber drafting. It can pre-wash away part of the solvent on the fiber by water washing and heating, reducing the pressure on subsequent equipment and meeting production process requirements.
