Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber production, in particular to a roller dehydration device for removing static electricity from carbon fiber precursor. Background Art

[0002] In the production process of carbon fiber, when the raw silk is put through the unwinding and pre-oxidation process, the friction with the guide rollers will cause the raw silk to generate a large amount of static charge. The static electricity will cause the charges on the silk bundles to repel each other, causing the silk bundles to become fuzzy and easy to wrap around the rollers, affecting the quality of the silk. The prior art generally sets a water immersion tank on the unwinding path of the raw silk, and the water in the water immersion tank humidifies it to weaken the static charge of the raw silk. However, after the raw silk is eliminated of static electricity in the water immersion tank, a part of the water is still adsorbed on the raw silk and follows the raw silk into the drying area, which will prolong the drying time and seriously affect the overall production efficiency.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] like Figures 1 to 3 The roller dehydration device for removing static electricity from carbon fiber precursor shown in the figure comprises: a frame 1, and a water immersion tank 2 arranged in the frame 1; two immersion rollers 3 are arranged in the water immersion tank 2, and two traction rollers 4 are symmetrically arranged on both sides of the water immersion tank 2 and above the water immersion tank 2;

[0025] Among them, a rolling assembly is provided above the traction roller 4 located at the outlet of the immersion tank 2, and the rolling assembly includes an extrusion roller 5, two swing arms 6 arranged at both ends of the extrusion roller 5, and two cylinders 7 arranged in a one-to-one correspondence with the two swing arms 6; the swing arms 6 are rotatably set on the frame 1, the extrusion roller 5 is set at the free ends of the two swing arms 6, the middle position of the swing arms 6 is provided with a force-applying end, the cylinder body of the cylinder 7 is hinged on the frame 1, and the driving rod of the cylinder 7 is hinged to the force-applying end.

[0026] In the specific implementation process, after the raw silk is released, it is conveyed by two traction rollers 4 and two immersion rollers 3. Through the guidance of the two immersion rollers 3, the raw silk is fully contacted with the liquid in the immersion tank 2 to perform preliminary static electricity removal treatment; the two cylinders 7 are started to act, and the two cylinders 7 synchronously drive the two swing arms 6 to swing, so that the squeezing roller 5 gradually approaches the traction roller 4 until the squeezing roller 5 abuts against the traction roller 4. At this time, the traction roller 4 drives the squeezing roller 5 to rotate synchronously to squeeze and dehydrate the raw silk coming out of the immersion tank 2. After dehydration, the raw silk continues to move along the production line and enters the next production link, and the squeezed excess water flows back into the immersion tank 2. The utility model can effectively remove excess water on the raw silk through the setting of the rolling assembly, avoiding reduced production efficiency and potential quality problems caused by extra water.

[0027] In order to reduce the stability of the swing arm 6 during the swinging process, a bearing seat 8 is provided at the connecting end of the swing arm 6 and the frame 1. The bearing seat 8 provides a stable connection point to ensure that the swing arm 6 will not deviate during operation. A first connecting shaft is provided at one end of the swing arm 6 close to the bearing seat 8. The first connecting shaft is rotatably arranged in the bearing inner hole of the bearing seat 8. The bearing can absorb vibrations during mechanical operation, reduce the impact on the entire dehydration device, and improve the stability of the overall machinery.

[0028] In the preferred embodiment, the squeezing roller 5 and the bearing seat 8 are arranged on the same side of the swing arm 6. During the installation process, first, the bearing seat 8 is pre-installed on the frame 1; secondly, the squeezing roller 5 is placed in the installation position, and the two swing arms 6 are installed at both ends of the squeezing roller 5 from both ends. At this time, the first connecting shaft of the squeezing roller 5 is synchronously installed on the bearing seat 8, which improves the convenience of installation.

[0029] In another preferred embodiment, the cylinder 7 is tilted away from the bearing seat 8, so that the swing arm 6 and the cylinder 7 share the weight of the squeezing roller 5, so as to reduce the load of the swing arm 6, effectively ensure the stability of the squeezing roller 5 in the pressing process, and make the distance from the hinge point of the drive rod of the cylinder 7 to the rotation point of the swing arm 6 greater than the distance from the hinge point of the drive rod of the cylinder 7 to the center of the squeezing roller 5. Taking the hinge point of the cylinder 7 as the reference point, the arm length of the left end close to the bearing seat 8 is greater than the arm length of the right end close to the squeezing roller 5. When the cylinder 7 lifts the swing arm 6 upward, the long arm length of the swing arm 6 can reduce the load of the cylinder 7, and the longer arm can provide a greater safety factor, reducing the risk of the squeezing roller 5 falling suddenly.

[0030] In the utility model, a driving motor is provided at the traction roller 4 located at the exit of the immersion tank 2. The driving motor can accurately control the rotation speed of the traction roller 4, thereby accurately controlling the tension of the raw silk, and ensuring the tension state of the raw silk after passing through the immersion tank 2. The stable traction force provided by the motor helps to reduce the breakage and relaxation of the raw silk, and can provide sufficient power to drive the squeezing roller 5 to rotate, so as to achieve dehydration of the raw silk.

[0031] In order to reduce the damage to the surface of the raw silk, a rubber layer 51 is provided on the surface of the squeezing roller 5 to provide a softer contact surface, so that the raw silk can be squeezed and dehydrated without damaging it.

[0032] In the preferred embodiment of the utility model, a shift fork 9 is provided at the end of the driving rod of the cylinder 7, and the swing arm 6 is placed between the two shifting pieces of the shift fork 9 and connected through a second connecting shaft; and a retaining spring is provided at both ends of the second connecting shaft. The arrangement of the shift fork 9 and the second connecting shaft effectively ensures the stability of the connection between the swing arm 6 and the cylinder 7, and the design of the retaining spring prevents the connecting shaft from accidentally falling off, thereby improving the safety of the equipment operation.

The above embodiments and the description are only for explaining the principle of the present invention.
