Description

Technical Field

[0001] The utility model relates to the technical field of ultra-short composite fiber testing, in particular to an electrostatic device for testing ultra-short composite fibers. Background Technique

[0002] Ultra-short fibers are a kind of lightweight reinforced filling material, which are widely used in asbestos-free brake pads and asbestos-free rubber sealing plates. It is made by precision shearing of glass fiber raw filaments and is suitable for fields such as friction materials, sealing materials, fiber cement products, non-woven fabrics, felts, and fiberglass products. Ultra-short fibers are not only a substitute for asbestos-free and metal-free materials, but also widely used in materials such as plastics, cement products, insulating materials, adhesives, fireproof and flame-retardant materials, friction and sealing materials, rubber, special papermaking, coatings, and spacecraft accessories;

[0003] During the production, processing or use of ultra-short fibers, they are prone to contact and friction with other objects to generate charged phenomena. If the charges accumulate continuously and are not eliminated, electrostatic phenomena will occur, which not only makes textile processing difficult, but also affects the use performance or causes hazards. By controlling the generation of static electricity in short fibers, the static electricity problem in the production process can be effectively reduced. If the static electricity of ultra-short fibers is directly tested, the true situation of the static electricity generated by the friction between fibers during the production and processing process cannot be obtained. This device accurately obtains the static electricity data during production by simulating the state of short fibers during processing;

[0004] Conventional detection devices have a simple structure and are prone to tipping during use, resulting in the operation of the device being affected. At the same time, it is relatively inconvenient to take out the fiber raw materials to be tested inside, and the operation is time-consuming and laborious.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an electrostatic device for testing ultra-short composite fibers is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide an electrostatic device for testing ultra-short composite fibers to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An electrostatic device for testing ultra-short composite fibers, including a device frame and a movable wire mesh frame. A test cylinder is vertically installed in the middle of the device frame, and a cover is installed on the top of the test cylinder. The movable wire mesh frame is installed inside the test cylinder. The movable wire mesh frame includes a filter disk, a telescopic rod, and a stabilizing frame. A telescopic rod is vertically installed in the middle of the filter disk, and the lower end of the telescopic rod is connected to the stabilizing frame.

[0008] Further, the device frame includes a fixed ring, a triangular frame, and a support frame. The side of the fixed ring is connected to the triangular frame, and the support frame is obliquely installed on the side of the triangular frame away from the fixed ring.

[0009] Furthermore, the tripod and the support frame are both installed in three groups in a circular array with the fixing ring as the center, and the fixing ring is installed in three groups in a vertical arrangement.

[0010] Furthermore, the test cylinder comprises a main cylinder body, a guide column, a docking ring, a sealing groove and a connecting valve. The guide column is installed on the inner wall surface of the main cylinder body, and the docking ring is installed on the top of the main cylinder body.

[0011] Furthermore, the test cylinder also includes a sealing groove and a connecting valve. A sealing groove is provided on the edge surface of the connection between the main cylinder body and the docking ring, and a connecting valve is installed at the lower end of one side of the main cylinder body.

[0012] Furthermore, the sealing cover comprises a cylinder cover, a cover handle and a sealing ring. The top of the cylinder cover is provided with a cover handle, and the bottom edge of the cylinder cover is provided with a sealing ring.

[0013] Furthermore, the inner surface structure of the sealing groove matches the outer surface structure of the sealing ring, and the cylinder cover and the docking ring are threadedly connected.

[0014] Furthermore, the guide posts are installed in a circular array with the main cylinder as the center, and the edge surface of the filter disc is provided with a groove structure matching the surface structure of the guide posts, and the edge surface of the filter disc is in contact with the inner wall surface of the main cylinder.

[0015] The utility model provides an ultra-short composite fiber test electrostatic device, which has the following beneficial effects:

[0016] 1. The utility model installs a movable grid frame inside the test cylinder, and utilizes the structural telescopic property of the telescopic rod to facilitate the operation of lifting or pushing down the entire movable grid frame from the inside of the device frame. At the same time, unnecessary structural interference will not be caused after the test cylinder and the cover structure are connected. The structure of the filter plate can effectively receive the fiber material inside the device frame. At the same time, since the edge surface of the filter plate is provided with a groove structure matching the guide column structure, the entire filter plate is slidably connected to the inner wall surface of the main cylinder body, thereby realizing the vertical and horizontal mobility of the movable grid frame inside the device frame, so that the fiber material tested inside the device frame can be taken out at one time, thereby ensuring the convenience and flexibility of the use of the entire device.

[0017] 2. In this utility model, by respectively providing sealing grooves on the bottom of the cylinder cover and the surface of the top edge of the main cylinder body, and at the same time connecting them through the threaded structure between the cylinder cover and the docking ring, the test cylinder and the cover can be quickly disassembled and assembled. By using the above structure, on the one hand, it can ensure to the greatest extent that there is sufficient connection tightness between the test cylinder and the cover, preventing problems such as pressure relief from affecting the test results. On the other hand, it also enables flexible structural disassembly and assembly between the test cylinder and the cover, so that the user can adjust at any time. In addition, by using the device frame, with three groups of support frames and tripod frames arranged around the fixed ring, it can ensure that the whole device has sufficient stability during use, preventing the occurrence of tilting due to external forces.

The edge surface is provided with a groove structure that matches the surface structure of the guide column 202, and the edge surface of the filter plate 401 is in contact with the inner wall surface of the main cylinder 201. The structural elasticity of the telescopic rod 402 can facilitate the operator to lift or push down the entire movable grid 4 from the inside of the device frame 1, and the structure of the filter plate 401 can effectively serve as a receiving device for the fiber material inside the device frame 1, and the fiber material tested inside the device frame 1 can be taken out at one time, thereby ensuring the convenience and flexibility of the use of the entire device.

[0025] like Figures 1 to 4 As shown, the device frame 1 includes a fixing ring 101, a tripod 102 and a support frame 103. The side of the fixing ring 101 is connected to the tripod 102, and the support frame 103 is obliquely installed on the side of the tripod 102 away from the fixing ring 101. The tripod 102 and the support frame 103 are installed in three groups in a circular array with the fixing ring 101 as the center, and the fixing ring 101 is installed in three groups in a vertical arrangement. The test cylinder 2 includes a main cylinder body 201, a guide column 202, a docking ring 203, a sealing groove 204 and a connecting valve 205. The guide column 202 is installed on the inner wall surface of the main cylinder body 201, and the docking ring 203 is installed on the top of the main cylinder body 201. The test cylinder 2 also includes a sealing groove 204 and a connecting valve 205.
