Description

Technical Field

[0001] This invention relates to the field of material flow performance testing technology, specifically to a device for testing the flow performance of fiber materials. Background Technology

[0002] Fiber materials include chopped fiber reinforced composites and continuous fiber reinforced composites. Chopped fiber reinforced composites are high-performance materials that use short fibers as reinforcements, which are uniformly dispersed in a matrix material and formed through a specific process. The most common method is to heat and melt pre-mixed chopped fibers and plastic granules (or powders) and then inject them into a mold for rapid molding.

[0003] To prevent fiber migration and aggregation during manufacturing, which could lead to uneven fiber distribution in the product, forming fiber-rich and fiber-poor areas, resulting in inconsistent strength and shrinkage rates in different parts of the product and causing warping deformation, it is necessary to analyze the flow properties of a fiber material before manufacturing it.

[0004] Existing fiber material flow performance testing devices involve injecting a fixed weight of material into a spiral mold with length graduations using an injection molding machine at a fixed pressure and temperature. After curing at a specified temperature, the flow performance data is directly read from the distance the material flows through the spiral mold cavity. However, the cured material is difficult to remove because it is embedded in the spiral groove, requiring manual removal with tools, which prolongs the testing time and reduces testing efficiency. If automatic ejection is required, a large number of ejector pins and matching drives need to be added below the spiral groove to eject the cured material. The addition of ejector pins and matching drives not only increases the length of the lower mold but also requires frequent replacement and maintenance of the ejector pins, resulting in a significant increase in cost.

[0005] Therefore, it is necessary to design a low-cost fiber material flow performance testing device that can automatically pull and drop materials without drive. Summary of the Invention

[0006] The purpose of this invention is to provide a device for testing the flow properties of fiber materials, so as to solve the problems mentioned in the background art.

[0008] According to the above technical solution, the injection mechanism includes a heating barrel fixedly connected to the upper side of the support frame, a first hydraulic cylinder fixedly connected to the upper side of the heating barrel, the output end of the first hydraulic cylinder passing through the heating barrel and fixedly connected to a pressure plate, a pouring plate passing through one side of the heating barrel, and an electric valve fixedly connected to the lower side of the heating barrel, with the input end of the electric valve passing through the heating barrel.

[0009] According to the above technical solution, the testing mechanism includes a second hydraulic cylinder fixedly connected to the upper side of the support frame. The output end of the second hydraulic cylinder passes through the support frame and is fixedly connected to a slide plate. A lower mold is fixedly connected to the upper side of the workbench. Two guide rods are fixedly connected to both sides of the lower mold. A sliding sleeve is slidably connected to the outer side of the guide rod. The outer side of the sliding sleeve is fixedly connected to the slide plate. An upper mold is fixedly connected to the lower side of the slide plate.

[0010] According to the above technical solution, the lower mold has four evenly spaced circular grooves inside, a material groove is located at the center of the lower mold, and a spiral groove is located on the outside of the material groove.

[0011] According to the above technical solution, four guide pillars are evenly arranged on the lower side of the upper mold, and several heating pillars are evenly arranged inside the upper mold. A flow guide tube is fixedly connected inside the upper mold. The flow guide tube is Z-shaped. A telescopic tube is fixedly connected to the input end of the flow guide tube. The input end of the telescopic tube is fixedly connected to the output end of the electric valve.

[0012] According to the above technical solution, one end of the guide tube is provided with a material pulling mechanism for automatically pulling out and putting down the solidified material. The material pulling mechanism includes a baffle fixedly connected inside the guide tube. A first sliding groove is fixedly connected to the center of the baffle. Four third clearance grooves are evenly connected to the outside of the first sliding groove. A second sliding groove is provided on one side of the third clearance groove. A third sliding groove is provided on the lower side of the second sliding groove. A sliding hole is provided on one side of the third sliding groove.

[0013] According to the above technical solution, a first spring is provided inside the first slide groove. One end of the first spring is fixedly connected to the first slide groove and the other end is fixedly connected to a sliding column. The sliding column is slidably connected to the first slide groove. Four first clearance grooves are evenly provided inside the sliding column. A third connecting rod is hinged inside the first clearance groove. The other end of the third connecting rod is hinged to a second connecting rod.

[0014] According to the above technical solution, the middle of the second connecting rod is hinged to the third clearance groove, the other end of the second connecting rod is hinged to the first connecting rod, the inside of the second sliding groove is slidably connected to the pressure block, the inside of the pressure block is provided with the second clearance groove, and the other end of the first connecting rod is hinged to the second clearance groove.

[0015] According to the above technical solution, a second spring is fixedly connected to the lower side of the pressure block, a sliding plate is slidably connected inside the third sliding groove, and an arc column is fixedly connected to the lower side of the sliding plate and the arc column is slidably connected to the sliding hole.

[0016] According to the above technical solution, the control panel is equipped with a database and a judgment module. The database contains identification photos of several cured spiral materials with different spiral lengths and surface conditions.

[0017] According to the above technical solution, after the camera captures the image of the cured spiral material, it will convert the image into an electrical signal and send it to the judgment module. The judgment module will first compare it with the identification photos of different spiral lengths and surface states of the cured spiral material in the internal database, pre-identify the surface state and spiral length of the current cured spiral material, and classify the flow properties of the fiber material into normal flow rate, excessively fast flow rate and excessively slow flow rate based on the obtained photos of the cured spiral material.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The extension of the output end of the second hydraulic cylinder not only drives the upper and lower molds to complete the mold closing action and inject fiber material, but also drives the internal structure of the material pulling mechanism to move, causing the four arc-shaped columns to slide out and become hook-shaped. After the fiber material is cured, the output end of the second hydraulic cylinder retracts, driving the upper mold to move upward. As the upper mold moves downward, the arc-shaped columns hook the center of the cured spiral material and pull it upward, thus causing the cured spiral material to come out of the spiral groove. After the cured spiral material comes out of the spiral groove, the four arc-shaped columns retract into the third slide groove, and the cured spiral material slides down along the outer wall of the stop column and falls above the lower mold for the camera to capture and detect the flowability of the fiber material. The entire process of pulling out and dropping the cured spiral material can be completed without the use of additional drive. Automatic material pulling and dropping indirectly speeds up the testing speed of each fiber material, achieving the effects of energy saving and high testing efficiency.

[0019] 2. The camera captures images of the cured spiral material and converts them into electrical signals, which are then sent to the judgment module. The judgment module compares these images with identification photos of cured spiral materials with different spiral lengths and surface states in its internal database. It pre-identifies the surface state and spiral length of the current cured spiral material and, based on the captured images of the cured spiral material, determines the flow rate of the fiber material and judges whether its flow performance is normal, thus achieving the effect of automatically monitoring the flow performance of the fiber material.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-10 The present invention provides a technical solution: a fiber material flow performance testing device, including a support frame 1, a workbench 6 fixedly connected inside the support frame 1, a detection mechanism 3 provided on the upper side of the workbench 6, an injection mechanism 4 for heating and injecting the test material on the upper side of the support frame 1, a camera 5 for photographing and imaging the cured spiral material fixedly connected to the inner wall of the support frame 1, and a control screen 2 fixedly connected to one side of the support frame 1.

[0023] Please see Figure 2 The injection mechanism 4 includes a heating barrel 44 fixedly connected to the upper side of the support frame 1. A first hydraulic cylinder 41 is fixedly connected to the upper side of the heating barrel 44. The output end of the first hydraulic cylinder 41 passes through the heating barrel 44 and is fixedly connected to a pressure plate 42. A pouring plate 43 passes through one side of the heating barrel 44. An electric valve 45 is fixedly connected to the lower side of the heating barrel 44, and the input end of the electric valve 45 passes through the heating barrel 44.

[0024] The specific description of the above structure is as follows: the extension and retraction of the output end of the first hydraulic cylinder 41 is used to drive the pressure plate 42 to move up and down along the inner wall of the heating barrel 44, thereby pressing the molten fiber material inside the heating barrel 44 downward. The electric valve 45 is used to pass the molten fiber material. The heating barrel 44 heats the metal wall of the barrel through the external electric heating coil and conducts it to the material. Under the action of electric heating, the resin matrix melts rapidly and the viscosity decreases.

[0025] Before testing, the material to be tested is poured into the heating tank 44 through the pouring plate 43. The heating tank 44 is started to heat the material. The output end of the first hydraulic cylinder 41 extends to control the pressure plate 42 to move downward to below the pouring plate 43 to prevent heat loss and accelerate the melting speed of the material. After the material melts and the upper mold 35 and lower mold 36 are closed, the electric valve 45 is opened. The output end of the first hydraulic cylinder 41 extends again, driving the pressure plate 42 to move downward, pressing the molten material downward and flowing into the interior of the upper mold 35 through the electric valve 45.

[0026] Please see Figure 3 The testing mechanism 3 includes a second hydraulic cylinder 31 fixedly connected to the upper side of the support frame 1. The output end of the second hydraulic cylinder 31 passes through the support frame 1 and is fixedly connected to a slide plate 32. A lower mold 36 is fixedly connected to the upper side of the worktable 6. Two guide rods 34 are fixedly connected to both sides of the lower mold 36. A sliding sleeve 33 is slidably connected to the outer side of the guide rod 34. The outer side of the sliding sleeve 33 is fixedly connected to the slide plate 32. An upper mold 35 is fixedly connected to the lower side of the slide plate 32.

[0027] Please see Figure 4The lower mold 36 has four evenly spaced circular grooves 363 inside, a material groove 361 is located at the center of the lower mold 36, and a spiral groove 362 is located on the outside of the material groove 361.

[0028] Please see Figure 5 and Figure 6 Four guide pillars 353 are evenly arranged on the lower side of the upper mold 35. Several heating pillars 352 are evenly arranged inside the upper mold 35. A guide tube 37 is fixedly connected inside the upper mold 35. The guide tube 37 is Z-shaped. A telescopic tube 351 is fixedly connected to the input end of the guide tube 37. The input end of the telescopic tube 351 is fixedly connected to the output end of the electric valve 45.

[0029] The specific explanation based on the above structure is as follows: When mold closing detection is required, the extension of the output end of the second hydraulic cylinder 31 drives the slide plate 32 to move downward, which indirectly drives the upper mold 35 to slide downward along the guide rod 34. The telescopic tube 351 is driven to extend until the guide post 353 of the upper mold 35 is completely inserted into the interior of the circular groove 363. At this time, the upper mold 35 and the lower mold 36 complete the mold closing.

[0030] The molten material flows into the interior of the guide tube 37 through the telescopic tube 351. The heating column 352 is used to keep the material flowing inside the guide tube 37 warm, preventing solidification due to temperature drop. The molten material passes through the interior of the guide tube 37 and impacts the surface of the baffle 389. When the melt encounters the baffle 389, it is split in two and flows around from both sides. This forces the melt channel to narrow instantly, the local flow velocity to increase, and the shear force to increase. The enhanced shear force helps to separate the tangled short fiber bundles, allowing the melt core and the surface flow to mix, balancing the overall temperature, reducing internal stress caused by temperature differences, and finally flowing into the material tank 361, and then into the spiral groove 362. The molten material flows in the spiral groove 362 until the material stops flowing and solidifies. The output end of the second hydraulic cylinder 31 retracts, driving the upper mold 35 to move upward and open the mold.

[0031] Please see Figures 6-10 The guide tube 37 has a material pulling mechanism 38 inside one end for automatically pulling out and putting down the solidified material. The material pulling mechanism 38 includes a baffle 389 fixedly connected inside the guide tube 37. A first sliding groove 3891 is fixedly connected to the center of the baffle 389. Four third clearance grooves 3892 are evenly connected to the outside of the first sliding groove 3891. A second sliding groove 3893 is provided on one side of the third clearance groove 3892. A third sliding groove 3894 is provided on the lower side of the second sliding groove 3893. A sliding hole 3895 is provided on one side of the third sliding groove 3894.

[0032] The first slide groove 3891 is provided with a first spring 381 inside. One end of the first spring 381 is fixedly connected to the first slide groove 3891 and the other end is fixedly connected to a slide column 382. The slide column 382 is slidably connected to the first slide groove 3891. The slide column 382 is provided with four first clearance grooves 3811 evenly inside. The first clearance groove 3811 is hinged to a third connecting rod inside. The other end of the third connecting rod is hinged to a second connecting rod 387.

[0033] The middle of the second link 387 is hinged to the third clearance groove 3892. The other end of the second link 387 is hinged to the first link 386. The inside of the second slide groove 3893 is slidably connected to the pressure block 388. The inside of the pressure block 388 is provided with the second clearance groove 3881. The other end of the first link 386 is hinged to the second clearance groove 3881.

[0034] The lower side of the pressure block 388 is fixedly connected to a second spring 383, and the interior of the third slide groove 3894 is slidably connected to a slide plate 384. The lower side of the slide plate 384 is fixedly connected to an arc column 385, and the arc column 385 is slidably connected to the slide hole 3895.

[0035] The specific description of the above structure is as follows: In the initial state, the slide bar 382 is popped out by the first spring 381, the lower end of the slide bar 382 is higher than the lower surface of the upper mold 35, the arc bar 385 is located inside the slide hole 3895, and the second spring 383 is not compressed.

[0036] When the mold is closed, the output end of the second hydraulic cylinder 31 extends and drives the upper mold 35 to move downward, thereby indirectly driving the material pulling mechanism 38 to move downward until the lower end of the slide column 382 contacts the material groove 361. The slide column 382 is pressed by the material groove 361 and slides upward along the first slide groove 3891. At this time, the first spring 381 is compressed. While the slide column 382 moves upward, it drives the third connecting rod to rotate, thereby driving the second connecting rod 387 to rotate around the center, and then driving the first connecting rod 386 to rotate, pressing the pressure block 388 downward.

[0037] The pressure block 388 slides down along the second slide groove 3893, causing the second spring 383 to compress. When the second spring 383 is compressed to its limit, it begins to press the slide plate 384. The slide plate 384 slides along the third slide groove 3894, indirectly causing the arc column 385 to slide outward along the slide hole 3895. The arc length of the arc column 385 is a quarter circle. This continues until the upper mold 35 and the lower mold 36 are closed. At this time, all four arc columns 385 slide out and become hook-shaped inside the material groove 361.

[0038] The molten material flows into the material tank 361, and then into the spiral groove 362. The molten material flows in the spiral groove 362 until it stops flowing and solidifies. The output end of the second hydraulic cylinder 31 retracts, causing the upper mold 35 to move upward. All four arc-shaped pillars 385 slide out and become hook-shaped, hooking the solidified spiral material out of the spiral groove 362. At this time, the lower end of the sliding pillar 382 is no longer pressed by the material tank 361, and the sliding pillar 382 is gradually ejected by the first spring 381. The sliding pillar 382 moves along the first sliding groove 3891. As the slide bar 382 moves downward, it drives the third link to rotate, which in turn drives the second link 387 to rotate around the center, which in turn drives the first link 386 to rotate, lifting the pressure block 388 upward. The pressure block 388 slides upward along the second slide groove 3893, which stretches the second spring 383. When the second spring 383 is stretched to its limit, it begins to pull the slide plate 384. The slide plate 384 slides along the third slide groove 3894, indirectly driving the arc column 385 to slide inward along the slide hole 3895.

[0039] Since the arc length of the arc column 385 is a quarter circle, there is also a quarter circle arc groove inside the solidified material in the material groove 361. When the arc column 385 retracts, it will not be blocked by the solidified material along the arc groove until the slide column 382 is completely ejected by the first spring 381. The arc column 385 is completely retracted into the third slide groove 3894. At this time, the solidified spiral material is no longer hooked by the arc column 385. The solidified spiral material has been pulled out from the spiral groove 362. The solidified spiral material slides down along the outer wall of the stop column 389 and falls above the lower mold 36. The camera 5 takes pictures of the solidified spiral material.

[0040] The control panel 2 is equipped with a database and a judgment module. The database contains identification photos of several cured spiral materials with different spiral lengths and surface conditions.

[0041] After camera 5 captures an image of the cured spiral material, it converts the image into an electrical signal and sends it to the judgment module. The judgment module first compares the image with identification photos of different spiral lengths and surface states of the cured spiral material in its internal database, pre-identifies the surface state and spiral length of the current cured spiral material, and classifies the flow properties of the fiber material into normal flow rate, excessively fast flow rate, and excessively slow flow rate based on the captured image of the cured spiral material.

[0042] When camera 5 captures a cured spiral material whose length is between 40% and 60% of the total length of the spiral groove 362, and the cured spiral material has a smooth, flat, and uniform color, with the fibers well wrapped by the resin, the judgment module determines that the flow rate of this fiber material is normal, and the control screen 2 displays that the flow rate of this fiber material is qualified.

[0043] When camera 5 captures a cured spiral material whose length is greater than or equal to 60% of the total length of the spiral groove 362, and the cured spiral material has scorch marks, bubbles, or bright stripes caused by excessive local resin on its surface, the judgment module determines that the flow rate of this fiber material is too fast, and the control screen 2 displays that the flow rate of this fiber material is unqualified.

[0044] When camera 5 captures a cured spiral material whose length is less than or equal to 40% of the total length of the spiral groove 362, and the cured spiral material has a rough, dull surface with wrinkles or wavy patterns, and the end of the spiral material is not fully filled, the judgment module determines that the flow rate of this fiber material is too slow, and the control screen 2 displays that the flow rate of this fiber material is unqualified.
