Description

Technical Field

[0001] This utility model relates to the field of glass fiber pultruded sheet production technology, specifically a fiber-threading board for glass fiber pultruded sheet production. Background Technology

[0002] The fiber assembly board plays a crucial role in the production of glass fiber pultruded sheets, functioning as a "fiber navigation system." This seemingly simple yet extremely critical "navigator" on the pultruded sheet production line ensures, through precise hole design and manufacturing, that thousands of glass fiber bundles are precisely, parallelly, orderly, and with minimal damage. This lays a solid foundation for subsequent resin impregnation, molding, and curing, ultimately determining the performance and quality of the pultruded sheet. Selecting wear-resistant materials, precisely machining the holes, correctly installing, and regularly maintaining the fiber assembly board are key aspects of ensuring the efficient and stable operation of the pultrusion production line. The fiber assembly board, through the rigidity and precision of its physical channels, transforms chaotic fiber groups into a highly ordered parallel array. Essentially, it is a spatial programming tool for fibers. Its core working principle can be summarized as: "splitting to prevent disorder, bundling to orient, guiding and tracking, and protecting to reduce damage," providing a structurally regular fiber reinforcement skeleton for subsequent resin impregnation and molding, directly determining the mechanical properties and yield rate of the pultruded sheet.

[0003] To address the issue that traditional glass fiber pultruded sheets cannot meet the requirements for ideal materials as pultruded sheets for wind turbine blades, a carbon fiber-glass fiber composite pultruded sheet and its production process and equipment have emerged (see patent number: 202010682557.3 for details). Currently, the pultruded sheet products used in wind turbine blade beams are generally traditional glass fiber pultruded sheets and traditional carbon fiber pultruded sheets. Traditional glass fiber pultruded sheets have a slightly lower cost, but they are heavier, have average mechanical properties, and their strength and stiffness are significantly insufficient. Since the blade length is directly proportional to the wind turbine power, the longer the blade, the larger the wind-receiving area, and the greater the wind turbine power. Therefore, as the blade length increases, the blade mass also increases significantly, which leads to a significant increase in load.

[0004] However, in the production of glass fiber pultruded sheets, if the yarn breaks during use, the yarn will loosen from its original taut state. During the loosening process, it is easily affected by the reaction force and will roll up and wrap around other yarns or fall directly out of the threading holes on the threading plate. As a result, there is a lack of pressure tools during the loosening process, which makes the subsequent splicing process more complicated and reduces the utilization rate.

[0005] To solve the above problems, a fiber optic pultrusion board for producing glass fiber pultruded sheets has emerged. Utility Model Content

[0006] The purpose of this utility model is to provide a yarn threading board for the production of glass fiber pultruded sheets, in order to solve the problem that the subsequent splicing is more complicated when the original tension becomes loose.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a yarn-threading plate for producing glass fiber pultruded sheets, comprising a yarn-threading plate body, wherein a plurality of yarn-threading holes are uniformly arranged at one end of the yarn-threading plate body, and a first fixing block and a second fixing block fixedly connected to the yarn-threading plate body are arranged on both sides of the top and the bottom of one end of the yarn-threading holes, and a limiting sleeve and a movable sleeve are respectively arranged on the opposite side of the two sets of first fixing blocks and second fixing blocks, and a pressure roller is arranged on the adjacent end face of the limiting sleeve and the movable sleeve;

[0008] Among them, the top of the limiting sleeve is provided with a rotating shaft on the side near the first fixed block, the top and bottom of the pressure roller are rotatably connected with a connecting piece, one side of the connecting piece is provided with a connecting cover extending to the other side, one side of the connecting cover is provided with a connecting block, one side of the connecting block is provided with a screw extending into the inside of the limiting sleeve, the side of the screw near the connecting block is provided with a nut, the other side of the screw is provided with a limiting block that is slidably connected to the limiting sleeve, and an elastic element is sleeved on the outside of the limiting block;

[0009] One side of the movable sleeve is provided with a limiting rod extending into it, and one side of the limiting rod is fixedly connected to the remaining set of connecting parts.

[0010] As a further embodiment of this utility model: a threaded hole extending to the other side is provided on one side of the inside of the connecting cover, the screw is threadedly connected to the connecting cover through the threaded hole, and the side of the connecting cover away from the nut extends into the inside of the limiting sleeve and is movably connected to the limiting sleeve.

[0011] As a further improvement of this utility model: one end of both the limiting sleeve and the movable sleeve is provided with a locking element that is fixedly connected to the yarn feeding plate body, and one end of the locking element is provided with a locking position. The limiting sleeve and the movable sleeve are both connected to the locking element by the locking position.

[0012] As a further improvement of this utility model: each end face of the rotating shaft away from the limiting sleeve is provided with a mounting block, and the mounting block is fixedly connected to the first fixing block and the second fixing block by screws respectively.

[0013] As a further improvement of this utility model, the top and bottom of the pressure roller are rotatably connected to the connecting member.

[0014] As a further improvement of this utility model, multiple sets of friction textures are evenly arranged on the outer side of the pressure roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using the nut and screw, rotating the nut causes the screw to rotate along the threaded hole inside the connecting block and connecting cover 204, thereby directly driving the side limit block to move along the limit sleeve. This shortens or lengthens the movable space inside the limit block and the limit sleeve, thus preventing the yarn from breaking due to excessive extrusion force during the extrusion process.

[0017] 2. By using the set rotating shaft, when threading the yarn through the yarn feeding hole, the shaft can be rotated as the base point to separate the limiting sleeve and the movable sleeve from the clamping position on the clamping device. Then, the pressure roller can be operated in the opposite direction with the rotating shaft as the base point, so that the limiting sleeve and the movable sleeve can be extended into the clamping position on the end face of the clamping device, thus realizing the yarn threading operation.

The embodiments of this utility model will be described below based on its overall structure.

[0025] Please see Figures 1-4 In this embodiment of the utility model, a yarn-threading plate for producing glass fiber pultruded sheets includes a yarn-threading plate body 1. A plurality of yarn-threading holes 101 are uniformly arranged at one end of the yarn-threading plate body 1. A first fixing block 102 and a second fixing block 103 are provided on both sides of the top and bottom of one end of the yarn-threading hole 101, which are fixedly connected to the yarn-threading plate body 1. A limiting sleeve 2 and a movable sleeve 4 are respectively provided on the opposite side of the two sets of first fixing blocks 102 and second fixing blocks 103. A pressure roller 3 is provided on the adjacent end face of the limiting sleeve 2 and the movable sleeve 4.

[0026] Among them, the top of the limiting sleeve 2 is provided with a rotating shaft 201 on the side near the first fixing block 102. The top and bottom of the pressure roller 3 are rotatably connected with a connecting member 301. One side of the connecting member 301 is provided with a connecting cover 204 extending to the other side. One side of the connecting cover 204 is provided with a connecting block 203. One side of the connecting block 203 is provided with a screw 205 extending into the inside of the limiting sleeve 2. The side of the screw 205 near the connecting block 203 is provided with a nut 206. The other side of the screw 205 is provided with a limiting block 207 that is slidably connected to the limiting sleeve 2. An elastic member 208 is sleeved on the outside of the limiting block 207.

[0027] The movable sleeve 4 has a limiting rod 401 extending into it on one side, and one side of the limiting rod 401 is fixedly connected to the remaining set of connecting parts 301.

[0028] In this embodiment: Connector 301 is used to connect flexible or rigid pipes and is a component of the software architecture. It realizes the link between components by modeling the interaction rules between components. Unlike components, connector 301 does not need to be compiled.

[0029] Elastic component 208 is a mechanical part that works by utilizing elasticity. The part is made of elastic material and deforms under the action of external force. After the external force is removed, it returns to its original shape. It is also called "spring". It is generally made of spring steel. Elastic component 208 has a variety of types. According to shape, it mainly includes helical springs, spiral springs, leaf springs, and special-shaped springs.

[0030] Please see Figures 1 to 4 The connecting cover 204 has a threaded hole on one side extending to the other side. The screw 205 is threadedly connected to the connecting cover 204 through the threaded hole. The side of the connecting cover 204 away from the nut 206 extends into the interior of the limiting sleeve 2 and is movably connected to the limiting sleeve 2.

[0031] In this embodiment: the screw 205 is a cylinder with helical grooves cut on its outer surface or a cone with conical helical grooves cut on its outer surface; the screw 205 has different heads, which are called external hexagonal screws; as can be seen from the extrusion process, the screw 205 works under high temperature, certain corrosion, strong wear, and high torque. Therefore, the screw 205 must be: heat resistant and not deformed at high temperatures; wear resistant and long service life; corrosion resistant as the material is corrosive; high strength to withstand high torque and high speed; good machinability; low residual stress and small thermal deformation after heat treatment, etc.

[0032] Please see Figures 1 to 4 Both the limiting sleeve 2 and the movable sleeve 4 are provided with a locking piece 104 at one end, which is fixedly connected to the yarn feeding plate body 1. Each locking piece 104 has a locking position at one end, and the limiting sleeve 2 and the movable sleeve 4 are connected to the locking piece 104 through the locking position.

[0033] Please see Figures 1 to 4 Each end face of the rotating shaft 201 away from the limiting sleeve 2 is provided with a mounting block 202. The mounting block 202 is fixedly connected to the first fixing block 102 and the second fixing block 103 respectively by screws 105.

[0034] In this embodiment: Screw 105 is usually used alone (sometimes with a washer), generally for fastening or locking, and should be screwed into the internal thread of the machine body.

[0035] Please see Figures 1 to 4 The top and bottom of the pressure roller 3 are rotatably connected to the connector 301.

[0036] In this embodiment, the pressure roller 3 is the core device for material composite processing through mechanical pressure between rollers. Its main body is a cylindrical structure made of rubber. According to its function, it can be divided into calendering roller, embossing roller, pressing roller, etc. It is commonly used in combination with cooling roller and calendering roller to form extrusion coating and calendering coating production lines. Modern pressure rollers 3 are generally equipped with independent drive motors and temperature control systems. They have formed standardized industrial applications in rubber tire production, adhesive tape manufacturing, plastic film lamination and other scenarios. Patent data shows that by cooperating with the engraving roller, uniform embossing can be achieved, and air bubbles can be eliminated and three-dimensional patterns can be formed in the processing of the material sheet.

[0037] Please see Figures 1 to 4 Multiple sets of friction textures are evenly arranged on the outer side of the pressure roller 3.

[0038] The working principle of this utility model is as follows: When in use, the yarn extends through the yarn-collecting hole 101 to the other end of the yarn-collecting plate body 1. If the yarn breaks, it can be squeezed by two sets of pressure rollers 3. Under the action of the elastic element 208, the yarn is elastically squeezed, which avoids the yarn from becoming loose and wrapped in other places or falling out of the yarn-collecting hole 101 after breaking, which would cause difficulties in subsequent threading. Then, since the pressure roller 3 and the connecting element 301 are rotatably connected, when the yarn is pulled by the traction device, it will directly drive the pressure roller 3 to rotate, and the pressure roller 3 will not squeeze the yarn. Too much squeezing force will cause the yarn to be elastically squeezed during the rebound process after it breaks, resulting in a pulling force that is greater than elastic squeezing.

[0039] When the pressure roller 3 does not exert enough pressure on the yarn, the screw 205 can be rotated by turning the nut 206 to rotate along the threaded hole inside the connecting block 203 and the connecting cover 204. This will directly drive the side limit block 207 to move along the limit sleeve 2, shortening or lengthening the movable space inside the limit block 207 and the limit sleeve 2. When the space is shortened, it will generate a pressure on the elastic element 208, and at the same time, it will shorten the movable space of the limit block 207. After the movable space is shortened, the pressure of the pressure roller 3 on the passing yarn will increase. Conversely, if the limit block 207 is adjusted in the opposite direction, the movable space of the limit block 207 will increase, and the pressure of the pressure roller 3 on the passing yarn will decrease. This will avoid the problem of yarn breakage due to excessive pressure or insufficient pressure during the yarn compression process, resulting in poor limiting support effect on the yarn after breakage.

[0040] When the yarn needs to be threaded through the yarn-gathering hole 101, the shaft 201 can be rotated as the base point to separate the limiting sleeve 2 and the movable sleeve 4 from the locking position on the locking piece 104. Then the yarn extends through the yarn-gathering hole 101 to the other end of the yarn-gathering plate body 1. Then the pressure roller 3 can be operated in the opposite direction with the shaft 201 as the base point to extend the limiting sleeve 2 and the movable sleeve 4 into the locking position on the end face of the locking piece 104. Thus, the pressure roller 3 can squeeze the yarn that has passed through the yarn-gathering hole 101, thereby realizing the yarn threading operation.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
