Technical Field

[0001] This utility model relates to the field of polyetheretherketone (PEEK) filament technology, and in particular to a drying device for the production of PEEK filaments. Background Technology

[0002] Polyetheretherketone (PEEK) is a polymer composed of repeating units containing one ketone bond and two ether bonds in its main chain structure. It is a special polymer material with physical and chemical properties such as high temperature resistance and chemical corrosion resistance. It is a type of crystalline polymer material with a melting point of 334℃, a softening point of 168℃, and a tensile strength of 132-148MPa. It can be used as a high-temperature resistant structural material and an electrical insulating material. It can be combined with glass fiber or carbon fiber to prepare reinforcing materials. A drying device is required during the production of PEEK filaments.

[0003] Chinese Patent No. CN213841640U discloses a drying device for the production of polyetheretherketone (PEEK) filaments, comprising: a drying chamber; through holes, with through holes provided on the top of the two side walls of the drying chamber; limiting rollers, with limiting rollers rotatably connected to both sides of the inner wall of the drying chamber and at one bottom end; a tensioning mechanism, with a tensioning mechanism fixedly installed at the center of the top of the inner wall of the drying chamber; and a heating mechanism, comprising an air outlet, a fixing frame, a drying layer, an exhaust fan, a heating rod, and a conveying pipe. A fixing frame is fixedly welded to the center of the bottom surface of the drying chamber, and an exhaust fan is fixedly installed at the center of the bottom of the inner wall of the fixing frame.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: when the existing drying equipment for polyether ether ketone (PEEK) filament production is drying, water adheres to the surface of the PEEK filament after cooling, which affects the drying speed and reduces the production rate of PEEK filament.

[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] 1. By setting up the mounting and winding components, the PEEK yarn is pulled onto the winding roller. Then, the motor is started to drive the winding roller to rotate, thereby moving the PEEK yarn in the drying chamber and winding up the dried yarn. This enables continuous production without interruption for drying operations, improving production efficiency and reducing waste caused by interruptions. Furthermore, after drying, the yarn is directly wound up by the winding roller for easy collection, further accelerating production efficiency.

[0025] 2. By using a beating mechanism and extrusion components, the water on the surface of the PEEK yarn is absorbed before it enters the drying chamber. The yarn is also shaken as it moves within the drying chamber, causing the moisture to fall off. This reduces the time and energy required for drying, thus improving drying efficiency and ensuring a more uniform drying process. Simultaneously, the shaking promotes the flow of hot air between the PEEK yarns, further enhancing drying uniformity and ensuring good shape and dimensional stability during drying, thereby improving the quality of the final product.

[0042] Example 2

[0043] like Figure 5 As shown, this utility model proposes a drying device for the production of polyether ether ketone (PEEK) filaments. Compared with Embodiment 1, this embodiment details the structure of the striking mechanism.

[0044] The striking mechanism includes a second rotating shaft 801, a driving wheel 802, a driven wheel 804, a transmission belt 803, and a striking assembly. The second rotating shaft 801 is located at the end of the motor 302 away from the first rotating shaft 303. The driving wheel 802 is located at the end of the second rotating shaft 801 away from the motor 302. The transmission belt 803 is located on the outside of the driving wheel 802. The driven wheel 804 is located on the side of the transmission belt 803 away from the driving wheel 802. When the motor 302 is started, the motor 302 drives the second rotating shaft 801 to rotate. The second rotating shaft 801 drives the driving wheel 802 to rotate. The driving wheel 802 drives the driven wheel 804 to rotate via the transmission belt 803. The striking assembly is located on the side of the driven wheel 804 and is used to cyclically strike the vibrating plate. The striking assembly includes a third connecting shaft 805, a support rod 806, a pressing element 807, a rotating plate 808, and a fourth connecting shaft 809. The third connecting shaft 805 is located at the axis of the driven wheel 804. The support rod 806 is rotatably located on the outside of the third connecting shaft 805, with one end of the support rod 806 away from the third connecting shaft 805 connected to the outside of the drying chamber 1. The pressing element 807 is located on the end of the driven wheel 804 away from the third connecting shaft 805. An installation plate 814 is provided on the inner side of the drying chamber 1. A spring 813 is provided on the top of the installation plate 814. A rotating plate 808 is provided on the top of the spring 813. A striking block 810 is provided on the top of the rotating plate 808. The side of the rotating plate 808... A connecting shaft 809 is rotatably mounted. The end of the connecting shaft 809 away from the rotating plate 808 is connected to the inside of the drying chamber 1. The driven wheel 804 drives the connecting shaft 805 to rotate. The connecting shaft 805 drives the pressing member 807 to rotate. When the pressing member 807 contacts the rotating plate 808, it lifts the rotating plate 808 upward, causing the rotating plate 808 to rotate on the connecting shaft 809. At this time, the spring 813 is compressed, and the pressing member 807 continues to rotate and disengages from the rotating plate 808. Under the action of the spring 813, the rotating plate 808 quickly rebounds and drives the striking block 810 to strike the vibrating plate. The vibrating plate causes the polyetheretherketone filament to shake, thereby shaking off the moisture and accelerating the drying rate.

[0045] In summary, when using this invention, the dryer 5 is started, and the dryer 5 emits hot air from the bottom upwards. Then, the polyetheretherketone (PEEK) filaments are passed through the first sponge roller 406 and the second sponge roller 407, and the ends are tied to the fixing ring 206. The sliding member 202 is controlled to slide within the straight slide rail 201. After the sliding member 202 moves to the other end of the drying chamber 1, the connector 204 is removed and inserted into the insertion hole 307 to be installed on the take-up roller 306. Then, the motor 302 is started, which drives the first rotating shaft 303 to rotate. The first rotating shaft 303 drives the second connecting frame 305 to rotate, and the second connecting frame 305 drives the take-up roller 306 to rotate, thereby moving and winding the PEEK filaments within the drying chamber 1. When the PEEK filaments move, the water on the surface is absorbed by the pressure of the two sponge rollers. When the absorbed water is near the moving extrusion block 403 and the second extrusion block 404 of the sponge roller, the extrusion block 403 can push the sponge roller... The water inside cylinder 406 is squeezed out, and the water inside sponge roller 407 is squeezed out by the second squeezing block 404. The squeezed-out water can fall and be collected through the inclined surfaces of the first squeezing block 403 and the second squeezing block 404. At the same time, the motor 302 drives the second rotating shaft 801 to rotate, the second rotating shaft 801 drives the driving wheel 802 to rotate, the driving wheel 802 drives the driven wheel 804 to rotate through the transmission belt 803, and the driven wheel 804 drives the connecting shaft 805 to rotate. The pressing component 807 is driven to rotate. When the pressing component 807 contacts the rotating plate 808, it will lift the rotating plate 808 upward, causing the rotating plate 808 to rotate on the connecting shaft 809. At this time, the spring 813 is compressed, and the pressing component 807 continues to rotate and disengages from the rotating plate 808. Under the action of the spring 813, the rotating plate 808 quickly rebounds and drives the striking block 810 to strike the vibrating plate. The vibrating plate drives the polyetheretherketone filament to shake, thereby shaking off the moisture on it and accelerating the drying rate.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
