Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber precursor production equipment, and in particular to a humidifier used for eliminating static electricity in carbon fiber precursor production. Background Art

[0002] In the carbon fiber production process, the static electricity problem of the precursor has always been a key factor restricting production quality and efficiency. Carbon fiber precursors usually have a high resistivity. During the traction and winding processes on the production line, static electricity charges are easily accumulated due to friction and other reasons. Static electricity accumulation can lead to many adverse consequences. On the one hand, static electricity may cause the precursors to adsorb and entangle with each other, making the arrangement of the precursors chaotic, seriously affecting the smooth progress of subsequent processing steps, such as causing operational difficulties in weaving and impregnation, and reducing production efficiency. On the other hand, the electrostatic discharge phenomenon may damage the physical structure and chemical properties of the precursor, resulting in a decrease in the strength of the precursor and poor surface quality, thereby reducing the final quality of the carbon fiber product.

[0003] Traditional methods of eliminating static electricity have certain limitations. For example, the effect of eliminating static electricity by grounding is often unsatisfactory for some complex structures or precursors in high-speed motion. The use of chemical antistatic agents to treat the precursor may introduce impurities, which may have a potential impact on the purity and performance of the carbon fiber. In addition, some simple spray humidification devices cannot accurately control the spray position, angle and uniformity, so it is difficult to comprehensively and effectively eliminate static electricity on the precursor, and may cause the humidity in the production environment to be too high, causing other problems. Therefore, there is an urgent need for an efficient, accurate and adaptable static electricity elimination humidifier specifically for carbon fiber production precursors to overcome the shortcomings of the existing technology and meet the increasingly high quality and efficiency requirements of carbon fiber production.

[0012] In the above-mentioned humidifier for eliminating static electricity in the production of carbon fiber precursor, the gear rack assembly includes a rack, and the rack is fixedly connected to the inner wall of the mounting groove, and a transmission gear is installed on the mounting shaft, and the transmission gear is meshed with the rack.

[0014] In the above-mentioned humidifier used for eliminating static electricity in the production of carbon fiber precursor, two T-shaped slide grooves are symmetrically installed on the outer wall of the U-shaped rotating frame, and two L-shaped fixing rods are symmetrically installed on the moving box. Each of the L-shaped fixing rods is installed with a T-shaped slider, and each T-shaped slider is slidably connected in the T-shaped slide groove at the corresponding position.

A plurality of nozzle seats are symmetrically connected on the upper sealing cylinder, and each nozzle is inserted into a nozzle seat corresponding to the position.

[0017] In the above-mentioned humidifier for eliminating static electricity of carbon fiber production precursor, the connecting sealing cylinder is connected to connecting pipe 1, the machine body is connected to connecting pipe 2, and the connecting hose is inserted into connecting pipe 1 and connecting pipe 2.

[0018] In the above-mentioned humidifier used to eliminate static electricity in the production of carbon fiber precursor, the thickness of the connecting sealing cylinder is greater than the thickness of the upper sealing cylinder and the thickness of the lower sealing cylinder, and sealing ring grooves are provided at the upper and lower ends of the connecting sealing cylinder, and the upper sealing cylinder and the lower sealing cylinder are slidably connected in the sealing ring grooves corresponding to the positions.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The lifting component can accurately adjust the height of the U-shaped rotating frame and its connected buffer cylinder and nozzle through the cooperation of the motor, threaded rod and limit slider. This enables the device to adapt to the layout differences of the carbon fiber precursors in the height direction on different production lines. Whether it is the precursors at a higher or lower position, it can ensure that the nozzle is at a suitable height for humidification operations, which greatly improves the adaptability of the device to different production environments.

[0021] 2. The rotating component can flexibly change the angle of the U-shaped rotating frame with the help of motor 3, thereby adjusting the spray angle of the nozzle. For carbon fiber precursors that may be at different tilt angles or curved paths during the production process, this function can ensure that the nozzle can be accurately aligned with the precursor, so that the humidification spray can evenly cover the surface of the precursor, effectively avoiding uneven humidification caused by angle problems.

[0022] 3. Since the rack is horizontally arranged on the inner wall of the installation groove, the installation shaft can achieve horizontal axial movement by meshing with the rack when rotating, thereby driving the buffer cylinder to move horizontally. In addition, the moving box can slide horizontally on the U-shaped rotating frame. The two horizontal adjustment mechanisms cooperate with each other to achieve all-round positioning of the nozzle on the horizontal plane. Whether it is the linear arrangement change of the raw silk in the horizontal direction or the local position adjustment in the plane, the device can respond quickly, so that the humidification range is greatly expanded in the horizontal dimension, ensuring that all parts of the raw silk can be fully humidified.

[0023] 4. The unique structural design of the buffer cylinder is conducive to spray uniformity. It consists of an upper sealing cylinder, a connecting sealing cylinder and a lower sealing cylinder. The connecting sealing cylinder can slide between the upper and lower sealing cylinders and has a sealing ring groove to ensure sealing. When the buffer cylinder is affected by various actions brought by the installation shaft transmission, the internal liquid can still be stably sprayed out through the nozzle. Multiple nozzles are symmetrically distributed on the buffer cylinder. Combined with the flexible adjustment ability of the buffer cylinder itself, it can ensure uniform distribution of spray in different positions and postures, avoiding excessive or insufficient local spraying, so that the surface humidity of the carbon fiber precursor is uniform, which is conducive to better elimination of static electricity.

[0024] 5. The connection and transmission design between the components are compact and reasonable. For example, the bevel gear transmission assembly is located in the mobile box, which effectively utilizes the space and accurately transmits the power of the motor to the installation shaft to realize the rotation of the installation shaft, thereby driving the movement of related components. The gear rack assembly, the sliding connection between the bearing moving seat and the limit frame and other structures all realize complex motion conversion and position adjustment functions in a limited space. The various components of the entire device work together and cooperate with each other. While realizing multi-dimensional adjustment and uniform spraying, there is no excessive redundant structure, which improves the overall reliability and stability of the device, reduces the probability of failure, and is conducive to long-term stable operation in environments such as carbon fiber production workshops.

[0025] In summary, the present invention has multi-dimensional adjustment function, the height, angle and horizontal position can be precisely controlled, it can adapt to various raw yarn layouts, the spray uniformity is good, the buffer cylinder structure ensures stable spraying, the structure is compact and has strong coordination, the various components are closely matched, the space utilization is efficient, the operation is stable and reliable, and it is beneficial to the static elimination of carbon fiber raw yarn.

A mounting shaft 26 is installed in the bearing moving seat 19 through a mounting bearing 25.

A wedge-shaped slide groove 28 is opened on each limit frame 16, and each wedge slide bar 20 is slidably connected in the wedge-shaped slide groove 28 at the corresponding position.

[0042] A buffer cylinder 5 is installed at the upper end of the mounting shaft 26, and a plurality of nozzles 6 are symmetrically inserted on the buffer cylinder 5. The buffer cylinder 5 is connected to the machine body 1 through a connecting hose 8. The buffer cylinder 5 includes an upper sealing cylinder 501 and a lower sealing cylinder 503. A connecting sealing cylinder 502 is slidably connected between the upper sealing cylinder 501 and the lower sealing cylinder 503. A plurality of nozzle seats 504 are symmetrically connected on the upper sealing cylinder 501, and each nozzle 6 is inserted in the nozzle seat 504 at a corresponding position. A connecting pipe 1 11 is connected to the connecting sealing cylinder 502, and a connecting pipe 2 7 is connected to the machine body 1, and a connecting hose 8 is inserted on the connecting pipe 1 11 and the connecting pipe 2 7. The thickness of the connecting sealing cylinder 502 is greater than that of the upper sealing cylinder 501 and the thickness of the lower sealing cylinder 503. Sealing ring grooves 505 are provided at the upper and lower ends of the connecting sealing cylinder 502, and the upper sealing cylinder 501 and the lower sealing cylinder 503 are slidably connected in the sealing ring grooves 505 at corresponding positions.

[0043] The U-shaped rotating frame 3 is provided with a mounting groove 27, and the mounting groove 27 is connected to the mounting shaft 26 through a gear rack assembly, the gear rack assembly includes a rack 13, and the rack 13 is fixedly connected to the inner side wall of the mounting groove 27, and a transmission gear 22 is installed on the mounting shaft 26, and the transmission gear 22 is meshed with the rack 13;

[0044] A moving box 10 is horizontally slidably connected to the U-shaped rotating frame 3, two T-shaped slide grooves 12 are symmetrically installed on the outer wall of the U-shaped rotating frame 3, and two L-shaped fixing rods 17 are symmetrically installed on the moving box 10. A T-shaped slider 21 is installed on each L-shaped fixing rod 17, and each T-shaped slider 21 is slidably connected in the T-shaped slide groove 12 at the corresponding position.

[0045] A motor 18 is installed on the side wall of the moving box 10, and the motor 18 is connected to the mounting shaft 26 through a bevel gear transmission assembly, and the bevel gear transmission assembly is located in the moving box 10.

[0046] Height adjustment of the buffer cylinder 5 and the nozzle 6: The lifting assembly is used to adjust the height of the buffer cylinder 5 and the nozzle 6. The motor 2 14 drives the threaded rod 15 to rotate. Since the limit slider is threadedly connected to the threaded rod 15, and the U-shaped rotating frame 3 is connected to the fixed frame 2 through the limit slider, when the threaded rod 15 rotates, the limit slider will slide up and down in the limit vertical groove of the fixed frame 2, thereby driving the U-shaped rotating frame 3 to move up and down, and then changing the height position of the buffer cylinder 5 and the nozzle 6, so that it can adapt to the humidification requirements of carbon fiber precursors of different heights.

[0047] Angle adjustment of the buffer cylinder 5 and the nozzle 6: The rotating assembly can change the angle of the buffer cylinder 5 and the nozzle 6. The output shaft of the motor three 4 is connected to the U-shaped rotating frame 3. When the motor three 4 is working, it can drive the U-shaped rotating frame 3 to rotate around the rotating connection between the limiting slider and the U-shaped rotating frame 3 (whose center line coincides with the center line of the output shaft of the motor three 4). In this way, the angle of the buffer cylinder 5 and the nozzle 6 can be adjusted so that the nozzle 6 can be aligned with the carbon fiber precursors at different angles.

When the motor 18 is working, the mounting shaft 26 is driven to rotate through the bevel gear transmission assembly. Since the rack 13 is horizontally arranged on the inner wall of the mounting groove 27, the transmission gear 22 on the mounting shaft 26 is meshed with it. When the mounting shaft 26 rotates, under the action of the gear rack transmission, the mounting shaft 26 will produce axial movement in the horizontal direction. The mounting shaft 26 is connected to the bearing moving seat 19 through the mounting bearing 25. The bearing moving seat 19 slides stably on the limit frame 16 through the cooperation of the wedge-shaped slide bar 20 and the wedge-shaped slide groove 28, thereby driving the buffer cylinder 5 to move horizontally, changing the horizontal position of the nozzle 6, and expanding the humidification range. At the same time, the buffer cylinder 5 is composed of an upper sealing cylinder 501, a connecting sealing cylinder 502 and a lower sealing cylinder 503.

[0049] The humidifying liquid in the body 1 enters the buffer cylinder 5 through the connecting pipe 2 7, the connecting hose 8, and the connecting pipe 1 11.
