Description

TECHNICAL FIELD

[0001] The utility model relates to glass fiber production and processing equipment technical field especially relates to a long glass fiber stable traction device. BACKGROUND

[0002] Long glass fiber, also known as glass fiber reinforced material, refers to a kind of composite material with glass fiber as reinforcing body, which is bound by resin, metal and other substrates. Long glass fiber is widely used due to its high strength, high modulus, high heat resistance, corrosion resistance and other characteristics.

[0003] The production method of long glass fiber mainly includes extrusion method, jet forming method and pre-impregnation method etc. Among them, pre-impregnation method is the most commonly used long glass fiber production technology. In pre-impregnation method, long glass fiber yarn is soaked in resin, and then long glass fiber reinforced plastic is formed by extrusion molding and other ways. Long glass fiber needs to be pulled and transported by traction device after extrusion.

[0004] At present, the common traction device usually adopts one or more pairs of rollers to clamp long glass fiber for traction, which has the advantages of simple structure and low cost. However, when long glass fiber is pulled by rollers, its tension is not constant, which leads to the fact that long glass fiber is easy to break and deform due to uneven stress, so that the stability and uniformity of long glass fiber cannot be guaranteed under the condition of high-speed continuous production, affecting the product quality and production efficiency. INVENTION CONTENTS

[0005] In view of the deficiencies of the prior art, the utility model provides a long glass fiber stable traction device, and the specific technical scheme is as follows:

[0006] A long glass fiber stable traction device, comprising a traction frame, a plurality of traction roller groups installed on the top of the traction frame for pulling long glass fiber, and a tensioning mechanism installed on the top of the traction frame for keeping the tension of long glass fiber constant when pulling, the traction roller group comprises a traction box movably arranged on the top of the traction frame and a traction roller body rotatably arranged in the traction box, the traction roller body comprises an upper traction roller and a lower traction roller for clamping and conveying long glass fiber in the middle, and a plurality of motors are fixedly installed on the outer wall of the traction box for driving the rotation of the traction roller body;

[0007] The tensioning mechanism comprises a grating sensor arranged between two adjacent traction roller groups for real-time monitoring of long glass fiber tension, speed and temperature, a plurality of electric push rods arranged on the top of the traction frame for driving the movement of the traction roller group and adjusting the distance between the traction roller groups, and a control mechanism arranged on the outer side of the traction box for controlling the electric push rod according to the detection information of the grating sensor, and a cooling mechanism is arranged on one side of the traction box for cooling the traction roller body.

[0008] Through the real-time monitoring of the long glass fiber stress, temperature and speed by the grating sensor in the tensioning mechanism, the control mechanism can adjust the distance between the traction roller groups in real time through the extension and retraction of the electric push rod according to the detected tension change, keep the long glass fiber tension constant, and significantly improve the stability and uniformity of the long glass fiber under the condition of high-speed continuous production.

[0009] Optionally, a fixed frame is fixedly arranged at the top of the traction frame between two adjacent traction boxes, and the grating sensor is fixedly installed at the inner top of the fixed frame.

[0010] Through the above technical scheme, the fixed frame can connect the traction frame and the grating sensor, and support and fix the grating sensor.

[0011] Optionally, a static electricity air gun for eliminating static electricity of the traction roller body and the long glass fiber is fixedly installed in the traction box.

[0012] Through the above technical scheme, the static electricity interference on the long glass fiber during high-speed movement can be reduced through the static electricity elimination of the static electricity air gun.

[0013] Optionally, the cooling mechanism comprises a heat exchange box fixedly arranged on the side of the traction box away from the motor, and a cooling circulating water machine fixedly installed on one side of the heat exchange box and communicated with the heat exchange box.

[0014] Through the above technical scheme, the traction roller body can be cooled and cooled through the heat exchange of the cooling circulating water machine, the heat exchange box, the heat exchange rod and the traction roller body, so that the influence of high temperature on the long glass fiber can be reduced.

[0015] Optionally, limit grooves are formed in the two sides of the traction box, and a limit plate is slidably connected between two adjacent limit grooves.

[0016] Through the above technical scheme, when the limit plate slides and the cleaning piece is abutted on the traction roller body, the fixed cleaning piece can clean the surface of the traction roller body, so that the accumulation of impurities does not affect the quality of the long glass fiber.

[0017] In summary, the present application has at least one of the following beneficial effects:

[0018] 1. By using an optical grating sensor inside the tensioning mechanism to monitor the stress, temperature, and speed of the long glass fiber in real time, the control mechanism can adjust the spacing of the traction roller group in real time according to the tension changes on the monitored side through the extension and retraction of the electric push rod. This maintains a constant tension of the long glass fiber, significantly improving the stability and uniformity of the long glass fiber under high-speed continuous production conditions. It also achieves precise control of the tension and speed of the long glass fiber, reducing the risk of breakage and deformation of the long glass fiber, and improving production efficiency and product quality.

[0019] 2. Cooling the traction roller through the cooling mechanism reduces the impact of high temperature on long glass fibers. The static elimination by the electrostatic air gun reduces the electrostatic interference experienced by the long glass fibers during high-speed movement, further reducing adverse factors in the production process and extending the service life of the device. When the limit plate slides and presses the cleaning component against the traction roller, the fixed cleaning component can clean the surface of the traction roller, preventing the accumulation of impurities that could affect the quality of the long glass fibers.

[0025] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0026] This utility model discloses a long glass fiber stabilizing traction device, referring to... Figures 1-2 It includes a traction frame 1, multiple sets of traction rollers and a tensioning mechanism. The traction frame 1 consists of a main board and outriggers. The main board can be made of high-strength aluminum alloy, which has good rigidity and corrosion resistance. The outriggers can be made of carbon steel with galvanized surface treatment to increase corrosion resistance.

[0027] ReferenceFigures 1-3 The traction roller assembly includes a traction box 2 movably mounted on top of the traction frame 1, and a traction roller body 21 rotatably mounted inside the traction box 2. The traction roller body 21 includes an upper traction roller and a lower traction roller for clamping and conveying the long glass fiber in the middle. The traction box 2 can support and limit the traction roller body 21. A fiber channel is formed between the upper traction roller and the lower traction roller, so that the long glass fiber is stably pulled through the channel. The traction roller body 21 can be made of high-hardness stainless steel, and the surface is precision ground to ensure smoothness and wear resistance. The upper traction roller and the lower traction roller in the traction roller body 21 can be selected according to different fiber diameters and materials, and different models and sizes can be selected.

[0028] Reference Figures 1-3 Multiple motors 22 are fixedly installed on the outer wall of the traction box 2 to drive the traction roller 21 to rotate. The motors 22 can be synchronous motors or other motors that can rotate synchronously. The synchronous rotation of the motors 22 is a public technology and will not be described in detail here. After the motors 22 are running, they will drive the traction roller 21 to rotate, thereby pulling and conveying the long glass fiber.

[0029] Reference Figures 1-2 The tensioning mechanism includes a grating sensor 31 located between two adjacent traction roller groups for real-time monitoring of the tension, speed, and temperature of the long glass fiber; multiple electric push rods 4 located on the top of the traction frame 1 for driving the traction roller groups to move and adjusting the spacing between the traction roller groups; and a control mechanism located outside the traction box 2 for controlling the electric push rods 4 based on the detection information from the grating sensor 31. The multiple electric push rods 4 are fixedly installed between two adjacent traction boxes 2 and between the fixed block on the top of the traction frame 1 and the adjacent traction box 2, so that the extension and retraction of the electric push rods 4 can drive the traction box 2 to move, thereby adjusting the spacing between the traction roller groups.

[0030] The grating sensor 31 can transmit the detected tension, speed and temperature information of the long glass fiber to the control mechanism. After processing, the control mechanism will control the electric push rod 4 to extend and retract, so as to adjust the spacing of the traction roller group in real time and keep the tension of the long glass fiber constant.

[0031] Reference Figures 1-2 The top of the traction frame 1 is fixedly provided with a fixed frame 3 located between two adjacent traction boxes 2. The grating sensor 31 is fixedly installed on the inner top of the fixed frame 3. The fixed frame 3 can connect the traction frame 1 and the grating sensor 31, and the fixed frame 3 can support and fix the grating sensor 31.

[0032] Reference Figures 1-2The control mechanism includes a control cabinet 5 fixedly installed on the outside of the traction box 2, and a PLC controller fixedly installed inside the control cabinet 5. The control cabinet 5 can install and protect the PLC controller. The PLC controller inside the control cabinet 5 can process the information transmitted by the grating sensor 31 according to the internal programming and control the electric push rod 4. The control mechanism can also control the speed of the motor 22 and automatically adjust the speed of the traction roller group according to the preset parameters to ensure the stability and uniformity of the long glass fiber. The motor 22, grating sensor 31, electric push rod 4 and PLC controller are all common devices, and their internal circuit connections and principles have been disclosed, so they will not be described in detail here.

[0033] Reference Figures 1-2 An electrostatic air gun 23 for eliminating static electricity from the traction roller 21 and the long glass fiber is fixedly installed inside the traction box 2. By eliminating static electricity through the electrostatic air gun 23, the electrostatic interference experienced by the long glass fiber during high-speed movement can be reduced, and the air blown out by the electrostatic air gun 23 can partially dissipate heat from the traction roller 21 and the long glass fiber.

[0034] Reference Figures 1-3 The traction box 2 is provided with a cooling mechanism for cooling the traction roller 21 on one side. The cooling mechanism includes a heat exchange box 6 fixedly installed on the side of the traction box 2 away from the motor 22, and a cooling circulating water machine 61 fixedly installed on one side of the heat exchange box 6 and communicating with the inside of the heat exchange box 6. The cooling circulating water machine 61 can exchange heat with the water in the heat exchange box 6, so that the temperature of the water in the heat exchange box 6 becomes lower.

[0035] Reference Figures 1-3 The traction roller body 21 is filled with water in its center. A heat exchange rod 62 is fixed at the center of the traction roller body 21, with one end extending into the heat exchange box 6. A stirring blade 63 is fixed on the outer wall of one end of the heat exchange rod 62 to agitate the water in the heat exchange box 6. The heat exchange rod 62 can be made of a material with high thermal conductivity, such as aluminum rod. The heat exchange rod 62 can conduct heat between the water in the traction roller body 21 and the water in the heat exchange box 6, so that the heat exchange box 6 can cool the traction roller body 21 and reduce the impact of high temperature on long glass fibers. After the stirring blade 63 rotates with the heat exchange rod 62 and the traction roller body 21, it can agitate the water in the heat exchange box 6, so that the water temperature in the heat exchange box 6 is uniform and the heat exchange effect is improved.

[0036] Reference Figure 2 and Figure 4The traction box 2 has limit grooves 24 on both sides, and a limit plate 7 is slidably connected between two adjacent limit grooves 24. A cleaning component 71 is fixedly provided on one side of the limit plate 7 and abuts against the outer wall of the traction roller body 21. Several elastic rubber blocks 72 are fixedly provided at the top and bottom of the limit plate 7 and abut against the limit grooves 24. The traction box 2 can support and limit the two ends of the limit plate 7 through the limit grooves 24. The cleaning component 71 can be a sponge or other object with cleaning effect.

[0037] When the limiting plate 7 slides and the cleaning component 71 presses against the traction roller 21, the fixed cleaning component 71 can clean the surface of the traction roller 21, preventing impurities from accumulating on the surface of the traction roller 21 and affecting the quality of the traction long glass fiber. In addition, the elastic rubber block 72 will be squeezed and pressed against the limiting groove 24 under elasticity to fix the moving limiting plate 7, so that the movement of the limiting plate 7 has strong resistance and will not move arbitrarily.

[0038] The implementation principle of a long glass fiber stabilizing traction device according to an embodiment of this utility model is as follows:

[0039] When in use, multiple motors 22 are turned on. After the motors 22 are running, they will drive the traction roller body 21 to rotate. After the upper traction roller and the lower traction roller body 21 rotate, they can clamp, pull and transport the long glass fiber in the middle.

[0040] Meanwhile, the grating sensor 31 can transmit the detected tension, speed and temperature information of the long glass fiber to the PLC controller in the control cabinet 5. After processing, the PLC controller will control the electric push rod 4 to extend and retract to adjust the spacing of the traction roller group in real time, keep the tension of the long glass fiber constant, and the PLC controller can automatically adjust the speed of the traction roller group according to the preset parameters to ensure the stability and uniformity of the long glass fiber.

[0041] Furthermore, in conjunction with the cooling circulating water machine 61, heat exchange box 6, heat exchange rod 62, and traction roller 21, the traction roller 21 can be cooled and de-temperatured, thereby reducing the impact of high temperature on long glass fibers. The stirring blades 63, after rotating with the heat exchange rod 62 and traction roller 21, can agitate the water in the heat exchange box 6, making the water temperature in the heat exchange box 6 uniform and improving the heat exchange effect. The static electricity elimination by the electrostatic air gun 23 can reduce the static interference experienced by the long glass fibers during high-speed movement, further reducing adverse factors in the production process and extending the service life of the device.
