Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber processing, in particular to an extrusion device used for processing glass fiber cloth. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance and comes in many varieties. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Glass fiber is made of six kinds of minerals, namely pyrophyllite, quartz sand, limestone, dolomite, colemanite and magnesia stone, through high-temperature melting, wire drawing, winding and weaving. Each bundle of fiber strands is composed of hundreds or even thousands of single filaments.

[0003] At present, in the process of producing glass fiber cloth in factories, a wire drawing machine is used to produce glass fiber filaments for making glass fiber cloth. At present, when producing glass fiber filaments, the wire drawing machine injects the molten material made by mixing various raw materials melted at high temperature into the storage barrel, and uses a reciprocating extrusion block to extrude the molten material in the storage barrel for wire drawing. In the process of the extrusion block moving and pushing the material in the storage barrel, when the extrusion block moves upward, the molten material will be sucked into the storage barrel through negative pressure, and when the extrusion block moves downward, the molten material sucked into the storage barrel will be squeezed and drawn into glass fiber filaments. However, in the process of the extrusion block moving upward to suck the molten material, air will enter the storage barrel, so that the drawn glass fiber filaments have problems of missing, hollow and broken, which affects the production quality of the glass fiber filaments. Therefore, we propose an extrusion device for glass fiber cloth processing to solve the above problems. Utility Model Content

[0021] A plurality of slender discharge pipes 15 connected to the fine discharge holes 14 are fixedly connected to the bottom of the square extrusion tank 1. The square extrusion tank 1 and the transition tank 2 are connected by a plurality of reinforcing plates 16. Two mounting plates 17 are fixedly connected to the bottom of the square extrusion tank 1.

[0022] The square extrusion tank 1 and the transition tank 2 are connected and communicated through a connecting pipe 4 and two transition pipes 5. A rotating shaft 6 is rotatably connected to the outer wall of the square extrusion tank 1. An L-shaped fixing plate 7 is fixedly connected to the outer wall of the square extrusion tank 1. The L-shaped fixing plate 7 penetrates the outer wall of the square extrusion tank 1 and a through hole is opened on the outer wall of the square extrusion tank 1. The outer wall of the L-shaped fixing plate 7 and the inner wall of the through hole are slidably connected.

[0023] A servo motor 8 is fixedly connected to the outer wall of the L-shaped fixing plate 7, the output shaft of the servo motor 8 is fixedly connected to the end of the rotating shaft 6, a square slider 9 is slidably connected to the inner wall of the square extrusion tank 1, a sealing gasket is fixedly connected to the outer wall of the square slider 9, and the outer wall of the sealing gasket is slidably connected to the inner wall of the square extrusion tank 1;

[0024] An L-shaped slide plate 10 is fixedly connected to the outer wall of the square slide block 9, a rack 11 is fixedly connected to the outer wall of the L-shaped slide plate 10, a horizontal plate 18 is fixedly connected to the outer wall of the square extrusion tank 1, the outer walls of adjacent racks 11 and the outer walls of the horizontal plate 18 are slidably connected, a gear 12 is fixedly sleeved on the outer wall of the rotating shaft 6, and both the two racks 11 are meshed and connected with the gear 12, and a check valve 13 is fixedly sleeved on the outer walls of the feed pipe 3 and the transition pipe 5;

[0025] The flow direction of the check valve 13 on the feed pipe 3 is from the high-pressure storage tank to the square extrusion tank 1, and the high-temperature raw material in the square extrusion tank 1 cannot flow back into the high-pressure storage tank through the feed pipe 3. The flow direction of the check valve 13 on the transition pipe 5 is from the square extrusion tank 1 to the transition tank 2, and the raw material cannot flow from the transition tank 2 back into the square extrusion tank 1.

[0026] The utility model can explain its functional principle through the following operation mode: the initial state of the device is as follows: Figure 1 As shown, at this time, the interior of the square extrusion tank 1 and the interior of the transition tank 2 are filled with high-temperature raw materials for making glass fibers, and the connecting pipe 4 and the transition pipe 5 are also filled with high-temperature raw materials, such as Figure 3 As shown, the output shaft of the servo motor 8 is started to rotate counterclockwise, the output shaft of the servo motor 8 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the gear 12 thereon to rotate;

[0027] The gear 12 will mesh and drive the two racks 11 to move, so that the racks 11 drive the L-shaped slide plate 10 and the square slider 9 to slide in the square extrusion tank 1, so that the two square sliders 9 move toward the middle, and the square slider 9 can pass the high-temperature raw materials in the square extrusion tank 1 through a plurality of fine discharge holes 14 into the slender discharge pipe 15, so that the high-temperature raw materials are ejected from the slender discharge pipe 15 and cooled to form glass fiber filaments for making glass fiber cloth;

When the two square sliders 9 are about to contact each other, the output shaft of the servo motor 8 is started to rotate clockwise, and the output shaft of the servo motor 8 drives the rotating shaft 6 to reverse, so that the rotating shaft 6 drives the gear 12 thereon to reverse;

[0029] The gear 12 will mesh and drive the two racks 11 to move in the opposite direction, so that the rack 11 drives the L-shaped slide plate 10 and the square slider 9 to slide in the opposite direction in the square extrusion tank 1, so that the two square sliders 9 move from the middle to the sides. At this time, the high-temperature raw material in the suction space of the square extrusion tank 1 is squeezed by the square slider 9, so that the high-temperature raw material enters the transition tank 2 through the transition pipe 5 and the check valve 13, and then the high-temperature raw material enters the injection space between the two square sliders 9 through the connecting pipe 4, so that the high-temperature raw material fills the main material space, so that the high-temperature raw material can continue to enter the fine discharge hole 14, so that the glass fiber yarn is continuously produced;

[0030] When the square slider 9 reaches Figure 1 In the state shown, the output shaft of the servo motor 8 is started to rotate counterclockwise, and the above main material process is repeated to allow the glass fiber yarn to be continuously produced;

[0031] Until the production of glass fiber yarn is completed, the square extrusion tank 1 and the transition tank 2 need to be cleaned in time. By injecting high-temperature cleaning water into the feed pipe 3, the high-temperature cleaning water can clean the feed pipe 3, the square extrusion tank 1, the transition pipe 5, the check valve 13, the transition tank 2, the connecting pipe 4, the fine discharge hole 14 and the slender discharge pipe 15, so that the device can be reused.
