Description

Technical Field

[0001] This utility model relates to the field of prepreg technology, and more specifically, to a novel composite material prepreg. Background Technology

[0002] Composite materials are new materials created by combining different material components using advanced material preparation technologies. Composite prepregs have advantages such as light weight, high specific strength, high specific stiffness, strong designability, good fatigue fracture resistance, corrosion resistance, good dimensional stability, and ease of large-area integral molding, and have been widely used in various fields.

[0003] Existing composite material prepreg machines are difficult to control the inlet and outlet of composite material impregnation in an efficient manner. They have low conveying efficiency, are inconvenient to use, and the internal dye becomes dirty after long-term use. They cannot be recycled and purified, making it difficult to quickly and successfully impregnate the fabric, resulting in poor effect and inconvenience in drying and blowing.

[0004] Chinese patent application number CN202022622753.X discloses a novel composite material prepreg machine, including a prepreg machine body, a feed inlet, a discharge outlet, a circulating pump, a blower, and conveying rollers. The feed inlet is located at the upper left end of the prepreg machine body, and the discharge outlet is located at the upper right end of the prepreg machine body. Conveying rollers are fixedly installed at both ends of the bottom and the middle of the top of the prepreg machine body, which facilitates the direct impregnation and dyeing of composite materials, direct control of filtration, purification, and recirculation discharge, efficient purification of impregnation dyes, control of rapid heating, and good drying effect.

[0005] However, as can be seen from the accompanying drawings in the instruction manual, when the material is impregnated by the fixed-position impregnation roller, a deviation between the input and output rates can easily cause the material to be subjected to excessive tension or be in a relatively loose state during the conveying process, affecting the impregnation effect. Furthermore, directly feeding the material into the prepreg box can easily bring dust from the material surface into the prepreg box during the conveying process, affecting the prepreg effect and reducing the product's pass rate and quality grade. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a novel composite material prepreg machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel composite material prepreg machine, comprising a prepreg tank, a conveying roller is provided on one side of the top of the prepreg tank for supporting and conveying the composite material, and a support roller is provided on the other side for conveying the prepreg material after impregnation. A first dust removal box and a second dust removal box are respectively provided on the upper and lower sides of the conveying roller. The first dust removal box and the second dust removal box can absorb and clean the dust on the surface of the input composite material, thereby achieving the function of dust removal. A first filter box is fixedly connected to the top of the first dust removal box, and a second fan is provided in the middle of the first dust removal box. The first filter box can filter and collect dust, and the second fan can facilitate dust suction.

[0008] The second dust collection box is equipped with a first fan and a second filter box in the middle. A drying box is installed on the top of the support roller. A filter plate is installed on the top of the drying box. A third fan and an electric heating tube are installed in the middle of the drying box. The inner cavity of the prepreg box is equipped with an impregnation roller and a tension adjustment mechanism. The first fan absorbs and cleans the dust at the bottom of the material on the top of the conveying roller, and filters it through the second filter box. The third fan carries external air through the filter plate and then conveys it downwards. After being heated by the electric heating tube, it is blown onto the composite material on the top of the support roller, thus drying the surface of the material. The impregnation roller allows the material to pass through the liquid in the middle of the prepreg box for easy impregnation. The tension adjustment mechanism allows for easy control of the tightness of the material conveying and facilitates automatic adjustment.

[0009] The bottom of the prepreg tank is provided with a main pipe and a first support plate. Multiple porous tubes are fixedly connected to one side of the main pipe. An air pump is provided on one side of the prepreg tank. By starting the air pump, gas is injected into the main pipe and porous tubes. By spraying out the gas, the liquid inside the prepreg tank can flow, thereby improving the impregnation effect. The stability of the porous tubes is also improved by the first support plate.

[0010] Preferably, the number of conveying rollers and support rollers is set to two. The first fan is located at the top of the second filter box, and an air inlet is opened at the top of the second dust removal box at a position corresponding to the first fan. Through the conveying rollers and support rollers, the material can be positioned horizontally at the bottom of the drying box and the first dust removal box, which facilitates drying and dust removal and improves the performance.

[0011] Preferably, the bottom of the first dust collector is provided with an air inlet, the top of the first dust collector is connected to the inner cavity of the first filter box, and the top of the first filter box is provided with an exhaust port. The first dust collector and the first filter box facilitate dust collection, making cleaning easier and improving the impregnation effect.

[0012] Preferably, the third fan is located at the top of the electric heating tube, the bottom of the drying box is provided with a perforated plate, and the support roller is located at the top of the prepreg box. When the third fan is started, the gas is heated by the electric heating tube and then applied to the material for drying.

[0013] Preferably, the porous tube is disposed at the bottom of the tension adjustment mechanism and the dyeing roller. One end of the porous tube is fixedly connected to the wall of the first support plate. The output end of the air pump is connected to the inner cavity of the main tube. The inner cavity of the main tube is connected to the inner cavity of the porous tube. By blowing gas out through the porous tube and moving the gas upward, the liquid inside the prepreg tank can flow, thereby improving the dyeing effect.

[0014] Preferably, the tension adjustment mechanism includes a second support plate fixed in the middle of the prepreg tank, an adjusting pressure plate at the bottom of the second support plate, a support frame at the bottom of the adjusting pressure plate, a pressure roller at the bottom of the support frame, a U-shaped cross-section of the support frame, symmetrically fixedly connected stabilizing sliders on both sides of the support frame, the cross-sectional shape of the stabilizing sliders being T-shaped, and a groove adapted to the stabilizing sliders being opened in the middle of the prepreg tank, the stabilizing sliders being disposed inside the groove.

[0015] Preferably, an electric push rod is fixedly connected to the top of the second support plate, and the output end of the electric push rod is fixedly connected to the top of the adjusting pressure plate. Stabilizing rods are symmetrically fixedly connected to both ends of the top of the support frame. The top end of the stabilizing rod passes through the top of the adjusting pressure plate and the second support plate and is fixedly connected to a limit plate. A spring is sleeved in the middle of the stabilizing rod. The spring is set between the support frame and the adjusting pressure plate. The spring pushes the support frame, causing the pressure roller to generate a downward force. The material squeezes the pressure roller and the spring, achieving a buffering effect. The pressure roller is controlled to squeeze the spring by starting the machine, which facilitates the control of the buffering pressure. The stability of the support frame movement is improved by the stabilizing slider.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model firstly uses a tension adjustment mechanism to tighten the material when it is loose by pressing the support frame with a spring. When the material is too tight, the pressure roller presses the spring with the pressure roller to achieve a buffering effect. The tension position can be adjusted by activating an electric push rod. Furthermore, the combination of the first and second dust collection boxes can absorb and clean the dust on both sides of the material when it is fed into the prepreg box, improving the impregnation effect and thus improving the quality of the finished product.

[0018] 2. This utility model also improves the stability of the support frame's up-and-down movement by setting a stabilizing rod, and further improves the stability of the support frame and pressure roller's movement by using a stabilizing slider. By starting the air pump and discharging gas through the porous pipe, the liquid inside the prepreg tank can be made to boil, achieving liquid flow and improving the dyeing effect. Furthermore, the drying box can dry the material after dyeing, improving the performance.

[0019] In summary, through the interaction of the above-mentioned multiple functions, it is possible to buffer the conveyed material, facilitate the automatic adjustment of the material conveying effect, and absorb and clean the dust on both sides of the material before it enters the prepreg tank, thereby improving the impregnation effect and improving the quality of the finished product.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1-4The present invention discloses a novel composite material prepreg machine, comprising a prepreg tank 1, a conveying roller 2 provided on one side of the top of the prepreg tank 1 for supporting and conveying the composite material, and a support roller 9 provided on the other side for conveying the prepreg material after impregnation. A first dust removal box 3 and a second dust removal box 5 are respectively provided on the upper and lower sides of the conveying roller 2. The first dust removal box 3 and the second dust removal box 5 can absorb and clean the dust on the surface of the input composite material, thereby achieving the function of dust removal. A first filter box 4 is fixedly connected to the top of the first dust removal box 3, and a second fan 8 is provided in the middle of the first dust removal box 3. The first filter box 4 can filter the dust, and the second fan 8 can facilitate dust suction.

[0027] The second dust collection box 5 has a first fan 6 and a second filter box 7 in the middle. A drying box 10 is installed on top of the support roller 9, and a filter plate 11 is installed on top of the drying box 10. A third fan 12 and an electric heating tube 13 are installed in the middle of the drying box 10. The pre-impregnation box 1 has an impregnation roller 14 and a tension adjustment mechanism in its inner cavity. A main pipe 15 and a first support plate 17 are installed at the bottom of the inner cavity of the pre-impregnation box 1. Multiple perforated pipes 16 are fixedly connected to one side of the main pipe 15. An air pump 18 is installed on one side of the pre-impregnation box 1. The first fan 6 absorbs and cleans the dust at the bottom of the material on top of the conveying roller 2, and the material passes through the second filter box 7. The external gas is filtered by the third fan 12 through the filter plate 11 and then conveyed downwards. After being heated by the electric heating tube 13, it is blown onto the composite material on the top of the support roller 9 to dry the material surface. The material is then passed through the liquid in the middle of the prepreg tank 1 by the dyeing roller 14 for easy dyeing. The tightness of the material conveying is easily controlled by the tension adjustment mechanism, which is convenient for automatic adjustment. The air pump 18 is started to inject gas into the main pipe 15 and the porous tube 16. The gas sprayed out can make the liquid inside the prepreg tank 1 flow, improve the dyeing effect, and improve the stability of the porous tube 16 by the first support plate 17.

[0028] As attached Figure 1 , 2As shown in Figure 4, there are two conveying rollers 2 and two support rollers 9. The first fan 6 is located on top of the second filter box 7. The top of the second dust collector 5 has an air inlet corresponding to the position of the first fan 6. The bottom of the first dust collector 3 has an air inlet. The top of the first dust collector 3 is connected to the inner cavity of the first filter box 4. The top of the first filter box 4 has an exhaust port. The third fan 12 is located on top of the electric heating tube 13. The bottom of the drying box 10 is provided with a perforated plate. The support roller 9 is located on top of the pre-impregnation box 1. The perforated tube 16 is located at the bottom of the tension adjustment mechanism and the impregnation roller 14. One end of the perforated tube 16 is connected to the wall of the first support plate 17. The air pump 18 is fixedly connected to the inner cavity of the main pipe 15, which in turn is connected to the inner cavity of the porous pipe 16. Through the conveying roller 2 and the support roller 9, the material can be positioned horizontally at the bottom of the drying box 10 and the first dust removal box 3, facilitating drying and dust removal and improving the performance. The first dust removal box 3 and the first filter box 4 facilitate dust collection and cleaning, improving the impregnation effect. The third fan 12 heats the gas through the electric heating tube 13 and then acts on the material, facilitating drying. The gas is blown out through the porous pipe 16 and moves upward, allowing the liquid inside the pre-impregnation box 1 to flow, improving the impregnation effect.

[0029] As attached Figure 2 , 3 As shown, the tension adjustment mechanism includes a second support plate 19 fixed in the middle of the prepreg tank 1. An adjusting pressure plate 20 is provided at the bottom of the second support plate 19, and a support frame 21 is provided at the bottom of the adjusting pressure plate 20. A pressure roller 22 is provided at the bottom of the support frame 21. The cross-section of the support frame 21 is U-shaped. Stabilizing sliders 27 are symmetrically fixedly connected to both sides of the support frame 21. The cross-sectional shape of the stabilizing sliders 27 is T-shaped. A groove adapted to the stabilizing sliders 27 is opened in the middle of the prepreg tank 1, and the stabilizing sliders 27 are disposed inside the groove. An electric push rod 26 is fixedly connected to the top of the second support plate 19. The output end of the electric push rod 26 is connected to the top of the adjusting pressure plate 20. The support frame 21 is fixedly connected to the top of the support frame 21. The top ends of the support frame 21 are symmetrically fixedly connected to the stabilizing rods 23. The top of the stabilizing rods 23 passes through the top of the adjusting pressure plate 20 and the second support plate 19 and is fixedly connected to the limiting plate 25. The middle part of the stabilizing rods 23 is fitted with a spring 24. The spring 24 is set between the support frame 21 and the adjusting pressure plate 20. The spring 24 pushes the support frame 21, causing the pressure roller 22 to generate a downward force. The material squeezes the pressure roller 22 and the spring 24, thus achieving a buffering effect. The pressure roller 22 is squeezed by the starter to control the pressure of the spring 24, which facilitates the control of the buffering pressure. The stability of the movement of the support frame 21 is improved by the stabilizing slider 27.

[0030] The working principle of this utility model is as follows: When in use, the composite material is fed into the prepreg tank 1 through the top of the conveying roller 2, and guided by the bottom of the pressure roller 22 and the dyeing roller 14 and output through the support roller 9.

[0031] During the dyeing process, the second fan 8 and the first fan 6 are started to clean the material on both sides of the top of the conveyor roller 2 by vacuuming. The third fan 12 conveys the gas downwards and heats it through the electric heating tube 13. The gas is then applied to the surface of the material on the top of the support roller 9 for easy drying.

[0032] At the same time, the air pump 18 is started to inject gas into the porous tube 16 to make the liquid inside the prepreg tank 1 flow and improve the impregnation effect;

[0033] When the composite material is loose, the spring 24 pushes the support frame 21, which can push the pressure roller 22 downward to tighten the material. When the material is tight, the pressure plate 20 squeezes the support frame 21 to squeeze the spring 24, which can achieve a buffering effect and improve the performance.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
