Description

Technical Field

[0001] This utility model relates to the field of mixed fiber pultrusion molding technology, specifically a pultrusion sheet apparatus. Background Technology

[0002] Pultruded sheets, with their advantages of high strength, corrosion resistance, and light weight, are widely used in many fields such as construction, transportation, and energy. Carbon fiber and glass fiber, among others, are impregnated with resin in an impregnation device. They are initially polymerized through slotted holes on the front and rear yarn collecting plates, and then further polymerized through slotted holes on a pre-curing plate. Finally, all the polymerized fibers are passed through slotted holes in a mold for heating and curing into a sheet. Because the mixed fibers are pulled from left to right, they first pass through the slotted holes on the front yarn collecting plate. To ensure the stability of the sheet forming, excess resin carried by the mixed fibers is scraped off by the slotted holes as they pass through. This scraped resin slides down the surface of the front yarn collecting plate. Over time, the resin solidifies and clumps on the front yarn collecting plate, forming a sticky residue. When all the mixed fibers have passed through the front yarn collecting plate, the resin adhering to it is not completely dried and drips like a viscous liquid. The dirt falls and blocks the front of the strip holes on the front yarn collecting plate, causing blockage and affecting the passage of mixed fibers during the next pultrusion of the sheet. Therefore, the existing technology requires periodically removing the dirt from the surface of the front yarn collecting plate after the equipment is used. The dirt is removed from the surface of the collecting plate from top to bottom by a scraper. During the removal process, the gel-like dirt is squeezed and deformed, and a small part of the dirt will sink into the strip holes. Therefore, after removing the dirt from the surface of the front yarn collecting plate, the existing technology also uses a high-pressure blowing mechanism to blow from the back of the strip holes to the front, so that the dirt trapped in the strip holes is blown out. However, the existing technology has a complex structure and requires multiple mechanisms to complete the above operation. First, the lifting mechanism moves the scraper down to remove the dirt, and then another lifting mechanism moves the blowing mechanism down (if the lifting mechanism and the collecting plate are on the same level, it will affect the pulling of the mixed fibers) to blow into the strip holes. Not only is the structure complex, but the operation is also cumbersome, affecting subsequent production. Utility Model Content

[0003] To address the technical problems mentioned in the background section, this utility model provides a pultrusion sheet apparatus, employing the following technical solution:

[0004] The device includes a mold with a mold strip hole inside that is connected to the mold. A fixed frame is fixedly connected to the left side of the mold. From left to right, a front yarn collecting plate, a rear yarn collecting plate, and a preforming plate are arranged inside the fixed frame. The front yarn collecting plate has several front yarn collecting plate strip holes, the rear yarn collecting plate has several rear yarn collecting plate strip holes, and the preforming plate has several preforming plate strip holes. The front yarn collecting plate and the rear yarn collecting plate have the same structure. A cleaning mechanism is provided on the fixed frame. The front yarn collecting plate is located inside the cleaning mechanism. A lifting mechanism is provided on each side of the front yarn collecting plate and is fixedly connected to the front yarn collecting plate.

[0005] Furthermore, the cleaning mechanism includes an air jet plate, which has several air jet plate slots with the same number and shape as the front yarn collecting plate slots. The bottom of the air jet plate is flush with the top of the front yarn collecting plate. A sealing cover is connected to the back of the air jet plate, and an air pipe is connected to the back of the sealing cover. L-shaped fixing plates are fixedly connected to both sides of the air jet plate. The L-shaped fixing plates are fixed to the upper part of the fixing frame. A connecting plate is fixedly connected to the bottom of the L-shaped fixing plate. A scraper is fixedly connected to the connecting plate. The front yarn collecting plate is movably attached to the inside of the scraper and the air jet plate.

[0006] Furthermore, the connection source for the air pipe is one of the following: an air compressor, an air tank, etc.

[0007] Furthermore, the lifting mechanism includes electric push rods disposed on both sides of the front yarn collecting plate, a square sleeve is fixedly connected to the output end of the electric push rod, a square rod is fixedly connected to the square sleeve, and the square rod is fixed to the side of the front yarn collecting plate.

[0008] Furthermore, a first fixing block and a second fixing block are respectively provided on the inner side of the fixing frame from left to right. The first fixing block is connected to the rear yarn collecting plate by bolt thread, and the second fixing block is connected to the preformed plate by bolt thread.

[0009] Furthermore, the preformed panel is made up of several identical panels joined together.

[0010] Furthermore, the number of mixed fibers is evenly distributed according to the number of strip holes in the front and rear yarn collecting plates, with a fiber count difference of ≤3 per layer.

[0011] Furthermore, the number of strip holes in both the front and rear yarn collecting plates is far greater than the number of strip holes in the preformed plate.

[0012] Furthermore, the inner surfaces of the strip holes in the front yarn collecting plate, the rear yarn collecting plate, the preform plate, and the mold are all plated with a smooth metal material.

[0013] This invention has the following advantages: When it is necessary to clean the dirt on the front surface of the front yarn collecting plate, the lifting mechanism is activated, which raises the front yarn collecting plate. The dirt on the front surface of the front yarn collecting plate is first scraped off by the cleaning mechanism. When the lifting mechanism stops, the front yarn collecting plate is directly in front of the cleaning mechanism. At this time, the cleaning mechanism blows high-pressure gas from right to left into the slotted holes of the front yarn collecting plate, spraying out the dirt trapped in the slotted holes. This invention only requires the lifting mechanism to raise the front yarn collecting plate and then blow gas into the slotted holes of the front yarn collecting plate to complete the removal of dirt from the surface of the front yarn collecting plate and the cleaning of dirt in the slotted holes of the front yarn collecting plate in one go. The equipment is simple, does not take up much space, and is easy to operate, thus improving the efficiency of subsequent production. Attached Figure Description

The front yarn collecting plate 4 has several front yarn collecting plate slots 7, the rear yarn collecting plate 5 has several rear yarn collecting plate slots 8, and the preforming plate 6 has several preforming plate slots 9. The mixed fibers first pass through the front yarn collecting plate slots 7 and then through the rear yarn collecting plate slots 7. The yarn board has strip-shaped holes 8, then passes through the strip-shaped holes 9 of the pre-forming plate and then through the strip-shaped holes 7 of the mold to reach the inside of the mold 1. It is heated and cured inside the mold 1 to form a board. The front yarn collecting plate 4 and the rear yarn collecting plate 5 have the same structure. The rear yarn collecting plate 5 is located between the front yarn collecting plate 4 and the pre-forming plate 6, which can further support the forming of the mixed fiber path. A cleaning mechanism is provided on the fixed frame 3. The front yarn collecting plate 4 is located inside the cleaning mechanism. A lifting mechanism is provided on both sides of the front yarn collecting plate 4. The lifting mechanism is fixedly connected to the front yarn collecting plate 4. The lifting mechanism drives the front yarn collecting plate 4 to rise and fall inside the cleaning mechanism.

[0023] The cleaning mechanism includes a jet plate 10, which has several jet plate slots 11 with the same number and shape as the front yarn collecting plate slots 7. The bottom of the jet plate 10 is flush with the top of the front yarn collecting plate 4. A sealing cover 12 is connected to the back of the jet plate 10, and an air pipe 13 is connected to the back of the sealing cover 12. The high-pressure gas in the air pipe 13 enters the sealing cover 12 and is then ejected through all the jet plate slots 11 on the jet plate 10. L-shaped fixing plates 14 are fixedly connected to both sides of the jet plate 10. The L-shaped fixing plates 14 are fixed to the upper part of the fixing frame 3. On the fixed frame 3, the jet plate 10 is suspended and fixed on the upper side of the front yarn collecting plate 4. The bottom of the L-shaped fixed plate 14 is fixedly connected to the connecting plate 15, and the scraper 16 is fixedly connected to the connecting plate 15. The front yarn collecting plate 4 is movably attached to the scraper 16 and the inner side of the jet plate 10, that is, the front part of the front yarn collecting plate 4 is close to the back of the scraper 16, and the back of the front yarn collecting plate 4 is close to the front part of the jet plate 10. The scraper 16 is fixed to the front side of the jet plate 10 through the connecting plate 15. The connection source of the air pipe 13 is one of the following: an air compressor, an air tank, etc., and the air pipe 13 is supplied with high-pressure gas through the air compressor or the air tank.

[0024] The lifting mechanism includes electric push rods 17 on both sides of the front yarn collecting plate 4. The bottom of the electric push rods 17 is fixed to the ground or other base and is fixed vertically upward. A square sleeve 18 is fixedly connected to the output end of the electric push rod 17. A square rod 19 is fixedly connected to the square sleeve 18. The square rod 19 is fixed to the side of the front yarn collecting plate 4. The electric push rod 17 drives the square sleeve 18, the square sleeve 18 drives the square rod 19, and the square rod 19 drives the front yarn collecting plate 4 to rise and fall.

[0025] The inner side of the fixing frame 3 is provided with a first fixing block 20 and a second fixing block 21 from left to right. The first fixing block 20 is connected to the rear yarn collecting plate 5 by bolt thread, and the second fixing block 21 is connected to the pre-forming plate 6 by bolt thread. Through the above connection, the rear yarn collecting plate 5 and the pre-forming plate 6 are fixed to the inner side of the fixing frame 3.

[0026] The preformed plate 6 is made up of several identical plates spliced ​​together, which lengthens the travel through the strip holes 9 of the preformed plate and makes the preforming of mixed fibers more stable.

[0027] The number of mixed fibers is evenly distributed according to the number of strip holes 7 in the front yarn collecting plate and the number of strip holes 8 in the rear yarn collecting plate. The difference in the number of fibers in each layer is ≤3, which makes the mixed fibers more stable during pultrusion and reduces the phenomenon of warping of the board after the mixed fibers are cured into a board.

[0028] The number of strip holes 7 in the front yarn collecting plate and the number of strip holes 8 in the rear yarn collecting plate are much greater than the number of strip holes 9 in the preformed plate. The mixed fibers in the strip holes 7 and the strip holes 8 in the front yarn collecting plate are reorganized and then enter the fewer strip holes 9 in the preformed plate. Then they enter the single mold strip hole 2, gradually aggregate, and then become a board.

[0029] The inner surfaces of the front yarn collecting plate strip holes 7, the rear yarn collecting plate strip holes 8, the preforming plate strip holes 9, and the mold strip holes 2 are all plated with smooth metal material, which greatly increases the wear resistance of each strip hole and reduces the friction of mixed fibers passing through each strip hole.

[0030] The working principle of this utility model is as follows: When it is necessary to clean the front surface of the front yarn collecting plate 4, the electric push rod 17 is started. The electric push rod 17 drives the square sleeve 18, the square sleeve 18 drives the square rod 19, and the square rod 19 drives the front yarn collecting plate 4 to rise. When the front yarn collecting plate 4 rises, the dirt on its front surface is scraped off by the scraper 16. When the dirt on the front yarn collecting plate 4 is scraped off from top to bottom, the electric push rod 17 stops. At this time, the front yarn collecting plate 4 is located directly in front of the air jet plate 10, and the strip holes 7 of the front yarn collecting plate and the strip holes 11 of the air jet plate overlap front and back. At this time, the air compressor is started, and high-pressure gas enters the air pipe 13. The high-pressure gas in the air pipe 13 enters the sealing cover 12. The high-pressure gas in the sealing cover 12 is sprayed out through each strip hole 11 of the air jet plate and sprays into the corresponding strip hole 7 of the front yarn collecting plate, blowing out the dirt trapped in the strip hole 7 of the front yarn collecting plate, thus completing the cleaning.

[0031] This invention is simple to operate, convenient to use, and suitable for widespread promotion and application. Although embodiments of this invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of this invention, the scope of which is defined by the appended claims and their equivalents.
