Description

Technical Field

[0001] The utility model relates to the field of carbon fiber needling, in particular to a barrel-shaped carbon fiber needling device. Background Art

[0002] As a new type of material, carbon fiber cloth is light, flexible, and has good air permeability, filtration, thermal insulation, moisture absorption and waterproof properties. With the improvement of the quality of life of urban and rural residents, its application in the daily necessities market is becoming more and more extensive. In the production process, there are two main reinforcement process technologies, namely spunlace process and needle punching process.

[0003] The spunlace process is to precisely spray high-pressure fine water flow onto a single-layer or multi-layer fiber web, using the impact force of the water flow to make the fibers intertwine and entangle with each other, thereby enhancing the overall strength and stability of the fiber web, and then forming a carbon fiber cloth with certain mechanical properties.

[0004] The needling process, also known as the dry needling process, is a process in which a needle plate equipped with hooks is used to penetrate and hook the fluffy fiber web, so that criss-cross connection points are generated inside the fiber web, and finally it is reinforced into a carbon fiber cloth. However, when processing cylindrical carbon fiber cloth, the fiber web is usually laid on the wall of a drum mold and a special barrel-shaped needling machine is used for operation. The working principle of this type of equipment is to rotate the mold and perform horizontal repeated needling at one place along the axis of the mold, but this method has certain limitations: on the one hand, because the mold needs to rotate circle by circle to complete the needling of the entire surface area, the overall needling efficiency is relatively low; on the other hand, due to the mechanism of mold rotation and horizontal needling, some areas, especially the gaps between adjacent needling paths, may be difficult to be effectively needled, which will affect the uniformity and overall needling quality of the carbon fiber cloth. Therefore, a barrel-shaped carbon fiber needling device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] Example 1

[0028] like Figure 1-9 As shown, a barrel-shaped carbon fiber needling device includes an equipment support base 1 and two reciprocating drive mechanisms 3 symmetrically arranged on the equipment support base 1, both reciprocating drive mechanisms 3 are provided with needling plates 7, and the needles on the two needling plates 7 are staggered. A barrel-shaped carbon fiber rotating support mechanism 4 is provided on the top of the equipment support base 1, and a barrel-shaped carbon fiber 5 located between the two needling plates 7 is provided on the barrel-shaped carbon fiber rotating support mechanism 4. A driving mechanism 6 transmission-connected to the two reciprocating drive mechanisms 3 is provided on the side of the equipment support base 1.

[0029] When in use, the driving mechanism 6 can drive the two reciprocating driving mechanisms 3 to simultaneously push the needling plates 7 thereon to perform reciprocating motion, thereby simultaneously performing needling work on both sides of the barrel-shaped carbon fiber 5, thereby improving the needling work efficiency. In addition, since the needles on the two needling plates 7 are staggered, the problem that the gaps between each row of needles on a single needling plate 7 cannot be effectively needled can be avoided.

[0030] It should be noted that, in the present embodiment, the barrel-shaped carbon fiber 5 is installed in the carbon fiber rotating support mechanism 4 from above the needling device by hoisting. In addition, the needles of the needling plate 7 are provided with hooks for needling. This is a mature technical means in this field, so it will not be described in detail here.

It should be noted that when the connecting rod 305 is rotated to the closest distance to the vertical plate 301 through the reciprocating turntable 304, the limiting telescopic rod 308 is in an extended state driven by the needling plate 7 and is located in the telescopic limit sleeve 3012, and its end will not interfere with the connecting rod 305.

At the same time, the arrangement of two support seats 401 on one side facilitates the improvement of the weight capacity of the barrel-shaped carbon fiber rotating support mechanism 4;

[0035] A second drive motor 405 connected to the side of one of the side support units is provided, and a transmission sprocket assembly 406 is provided between the second drive motor 405 and the connecting shaft 403.

In addition, the tension of the transmission chain between the drive mechanism 6 and the two reciprocating drive mechanisms 3 can be adjusted through the tension adjustment mechanism.

[0038] In the preferred embodiment, the spacing adjustment mechanism 2 includes two limit slide bars 201 and a rotatable screw 202 arranged in the groove 101, a bearing for the screw 202 to rotate is arranged on the inner wall surface of the groove 101, two opposite sections of thread are arranged on the screw 202, and a third drive motor 203 is arranged on the side of the equipment support seat 1, one end of the screw 202 passes through the groove 101 and is connected to the output end of the third drive motor 203, and the power of the third drive motor 203 can drive the screw 202 to rotate;

[0039] The bottom of the vertical plate 301 is provided with a threaded hole 3014 and a limiting hole 3013 which are compatible with the screw rod 202 and the limiting slide rod 201.

The tension of the tensioning spring 604 can enable the first drive motor 605 to adapt to the change in the spacing between the two reciprocating drive mechanisms 3, so that the transmission chain maintains tension. It should be noted that the spacing between the base plate 601 and the top plate 609 is adapted to the spacing adjustment distance of the two reciprocating drive mechanisms 3.

[0041] Two locking screws 607 passing through the support plate 603 are symmetrically arranged between the bottom plate 601 and the top plate 609. The two locking screws 607 are respectively located on both sides of the first drive motor 605.
