Description

Technical Field

[0001] The invention belongs to the technical field of glass fiber elastic felt processing, and in particular relates to a glue atomization spraying process for glass fiber elastic felt. Background Art

[0002] Glass fiber is an inorganic non-metallic material with many advantages such as good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. Therefore, it has become the most widely used type of matrix material in reinforced composite materials. For example, in the production of glass fiber elastic felt, the main raw materials of glass fiber elastic felt include quartz sand, dolomite and other natural minerals. The continuous mining of natural minerals will cause a series of ecological environment and social problems such as surrounding land destruction, vegetation loss, groundwater system destruction and air pollution. In order to vigorously promote the reduction of industrial solid waste at the source and large-scale efficient comprehensive utilization in key industries, and accelerate the high-value recycling of renewable resources, coal-based materials are used as the main raw materials for the production of glass fiber.

[0003] Since the elastic felt produced by using glass fiber has a certain fluffiness, the elastic felts will stick to each other and are not easy to separate. In order to better shape and layer, it is necessary to stick a layer of relatively compact black felt on the surface of the elastic felt. During the pasting process, it is necessary to spray glue on the surface of the elastic felt so that the elastic felt and the black felt are bonded together. However, the existing glue spraying device directly sprays glue on the surface of the elastic felt, and the elastic felt is in a horizontal state during the spraying process. Since the glue has a certain fluidity and permeability, it is easy for the glue to flow into the inside of the elastic felt, so that the glue penetrates into the inner layer, hardens the inner layer of the elastic felt, and affects the elasticity. In addition, there is relatively little glue on the surface of the elastic felt, which makes it easy for the elastic felt and the black felt to be unreliable, and the thickness of the glue spraying cannot be well guaranteed. Therefore, a glue atomization spraying process for glass fiber elastic felt is needed. Summary of the invention

[0020] 1.

During the vertical transportation, the glue is sprayed onto the surface of the elastic felt body through the atomizing glue spray head. Since it is a horizontal spray, the glue will not flow and penetrate into the inner layer of the elastic felt body. In addition, when the elastic felt body is vertically transported downward, the glue in the form of dots on the surface is smoothed by the scraper, so that the glue distribution is more even, and the excess glue will be scraped off by the scraper, so that the thickness of the sprayed glue can be controlled to prevent the glue thickness from being too thick and affecting the bonding effect between the elastic felt body and the black felt body.

[0021] 2. In the present invention, the second motor drives the rotating roller to rotate, so as to drive the movable rod and the arc pressure plate to rotate. Since the black felt body slides down from the upper side of the arc pressure plate, the black felt body is fitted on the surface of the elastic felt body transported downward on one side of the vertical plate. Since the surface of the elastic felt body has been sprayed with glue at this time, the black felt body can be squeezed and fitted on the surface of the elastic felt body. Moreover, since a pressing spring is provided between the interior of the rotating roller and the movable rod, the arc pressure plate at one end of the movable rod can move freely when pressing the black felt body on the surface of the elastic felt body. The pressing spring can prevent the pressing force from being adjusted, and prevent the arc pressure plate from being rigidly pressed on the surface of the black felt body to damage the black felt body. On the one hand, the pressing force can be adjusted, and on the other hand, the black felt body and the elastic felt body of different thicknesses can be pressed and bonded, thereby improving the scope of use of the bonding and the practicability of the device.

Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] Embodiment: Before producing glass fiber elastic felt from coal-based materials, the coal-based materials need to be pretreated.

When in use, the unwinding elastic felt roller 20 is placed in the support block 160 of the unwinding mechanism 16 6, and then the unwinding elastic felt roller 20 is driven to rotate by the second servo motor 1605 on one side of the support block 1606, so that the elastic felt body 19 on the unwinding elastic felt roller 20 can pass through the upper guide roller 6 and slide downward in contact with the surface of one side of the vertical plate 2, so that the elastic felt body 19 passes through the lower guide roller 13 at the lower end of the vertical plate 2, and finally the elastic felt body 19 is wound onto the winding elastic felt roller 21 on the winding mechanism 17, and the winding elastic felt roller 21 is driven to rotate by the second servo motor 1605 on the support block 1606 of the winding mechanism 17, so that the elastic felt body 19 on the unwinding elastic felt roller 20 is wound onto the winding elastic felt roller 21, and the transfer of the elastic felt body 19 is completed.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8As shown, a loading plate 3 is arranged in the middle of the first cavity 201, and an arc base 18 is arranged on the upper side of the loading plate 3. An arc surface is arranged on the upper surface of the arc base 18, so as to facilitate the positioning of the unwinding elastic felt roller 20 and the winding elastic felt roller 21 to prevent shaking. Positioning mechanisms 5 are arranged on both sides of the arc base 18. The positioning mechanism 5 includes a positioning plate 501 rotatably arranged on the upper edge of the arc base 18, and a triangular protrusion is arranged on the upper end of the positioning plate 501, so as to facilitate the unloading and loading of the unwinding elastic felt roller 20 and the winding elastic felt roller 21 on the arc base 18.

When in use, the unwinding elastic felt roller 20 and the winding elastic felt roller 21 can be placed in batches into the upper side of the arc base 18 through the second sealing door 29. During the placing process, the unwinding elastic felt roller 20 or the winding elastic felt roller 21 will squeeze the triangular protrusion on the upper end of the positioning plate 501, so that the unwinding elastic felt roller 20 or the winding elastic felt roller 21 slides over the positioning plate 501 and falls into the upper side of the arc base 18. After placing, the positioning plate 501 is squeezed by the positioning spring 502, so that the positioning plate 501 can squeeze the unwinding elastic felt roller 20 or the winding elastic felt roller 21, so that the unwinding elastic felt roller 20 or the winding elastic felt roller 21 is fixed on the upper side of the arc base 18, to prevent the unwinding elastic felt roller 20 or the winding elastic felt roller 21 from rotating during loading, thereby affecting the loading accuracy.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a lifting mechanism 4 for driving the lifting movement of the loading plate 3 is provided on one side of the first cavity 201, and the lifting mechanism 4 includes a guide rail 401 fixedly arranged vertically in the middle of the inner side of the first cavity 201, a screw rod 403 is rotatably arranged on the inner side of the guide rail 401, and a first servo motor 402 for driving the screw rod 403 to rotate is provided on the top of the bonding box 1, and a threaded sleeve 404 is provided on the screw rod 403 to slide with the guide rail 401, and one side of the loading plate 3 is fixedly arranged on one side of the threaded sleeve 404, and when performing During the glue atomization spraying process, the first servo motor 402 drives the screw rod 403 to rotate, so that the threaded sleeve 404 on which the threaded sleeve is mounted can be lifted and lowered under the action of the guide rail 401, thereby driving the loading plate 3 on one side of the threaded sleeve 404 to lift and lower, so that the unwinding elastic felt roller 20 and the winding elastic felt roller 21 on the loading plate 3 can be lifted and lowered, so that the unwinding elastic felt roller 20 and the winding elastic felt roller 21 are respectively loaded onto the unwinding mechanism 16 and the winding mechanism 17, and can also unload.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a feeding shaft 14 is arranged in the middle of the inner side of the second cavity 202, and a first motor 1401 for driving the feeding shaft 14 to rotate is arranged on the rear side of the bonding box 1, and a black felt roller 23 is sleeved on the feeding shaft 14, and the black felt body 24 on the black felt roller 23 passes through the upper side of the pressing mechanism 15 and is attached to the surface of the elastic felt body 19 on one side of the vertical plate 2. When the glue atomization spraying process is carried out, the black felt roller 23 can be sleeved on the feeding shaft 14 through the first sealing door 28, and then the black felt body 24 bypasses the upper side of the pressing mechanism 15, so that the black felt body 24 is attached to the surface of the elastic felt body 19 on one side of the vertical plate 2. Since the surface of the elastic felt body 19 is sprayed with glue, the black felt body 24 can be bonded to the surface of the elastic felt body 19.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Fig.10 As shown, a dust collecting mechanism 7 and a glue spraying mechanism 8 are sequentially arranged on the inner side of the second cavity 202 from top to bottom.

The air inlet of the dust collector 701 is connected with the dust collecting hood 703 through a dust collecting pipe 702. When the glue atomization spraying process is performed, the elastic felt body 19 on one side of the vertical plate 2 will slide down from the upper guide roller 6 at the upper end of the vertical plate 2, so that the elastic felt body 19 will slide down in contact with the vertical surface of the vertical plate 2. The surface of the elastic felt body 19 is somewhat fluffy and has broken glass fibers on it.

The lower end of the scraper 9 is rotatably provided with a guide plate 10, and the inner side wall of the bonding box 1 is fixedly provided with a collection plate that cooperates with the lower end of the guide plate 10.

On the one hand, different thicknesses of glue can be scraped off, and on the other hand, the glue on the surface of the elastic felt body 19 of different thicknesses can be smoothed and scraped off, thereby improving the practicability of the device.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Fig. 9 , Fig.11As shown, a pressing mechanism 15 is arranged below the scraper 9, and the pressing mechanism 15 includes a rotating roller 1501 rotatably arranged inside the second cavity 202, and a second motor 1506 driving the rotating roller 1501 to rotate is arranged at the rear side of the bonding box 1, and a plurality of movable grooves 1504 are provided on the inner circumference of the rotating roller 1501, and three arc-shaped pressing plates 1503 are arranged on the circumference of the rotating roller 1501, and the inner ends of the three arc-shaped pressing plates 1503 adopt an arc structure, and the specific number of the arc-shaped pressing plates 1503 can be flexibly adjusted according to the process, and the present embodiment takes three arc-shaped pressing plates 1503 as an example, and each arc-shaped pressing plate 1503 is provided with a plurality of movable grooves 1504, and the inner circumference of the rotating roller 1501 is provided with a plurality of movable grooves 1504, and the inner circumference of the rotating roller 1501 is provided with three arc-shaped pressing plates 1503. The central angle of a curved pressure plate 1503 is 115°, and the radius of each curved pressure plate 1503 is 0.5m, so the arc length of each curved pressure plate 1503 is 1m, and the radius of each curved pressure plate 1503 can be adjusted according to needs, so that the length of each curved pressure plate can be adaptively adjusted. A gap is set between two adjacent rows of curved pressure plates 1503, and a plurality of movable rods 1502 that are slidably connected to the inner side of the movable groove 1504 are fixedly set on the inner side of each curved pressure plate 1503, and one end of the plurality of movable rods 1502 is fixedly A pressing spring 1505 fixedly connected to the bottom of the movable groove 1504 is provided. When the black felt body 24 is pressed against the surface of the elastic felt body 19, the three arc-shaped pressing plates 1503 outside the rotating roller 1501 can be rotated counterclockwise by only driving the rotating roller 1501 counterclockwise through the second motor 1506. Since the black felt body 24 is attached to the surface of the arc-shaped pressing plates 1503 from top to bottom, when the three arc-shaped pressing plates 1503 rotate counterclockwise, the black felt body 24 will be pressed against the surface of the elastic felt body 19, and since the three arc-shaped pressing plates 1503 are rotated counterclockwise, 03 and the rotating roller 1501 through multiple movable rods 1502 and a pressing spring 1505 at the lower end of each movable rod 1501, which can buffer the force of the arc-shaped pressing plate 1503 pressing the black felt body 24 onto the elastic felt body 19, so that the pressing force is slowly increased, thereby improving the pressing effect of the glue on the surface of the elastic felt body 19 and the black felt body 24, preventing separation, improving the reliability of the bonding, and avoiding sudden excessive pressing force to damage the black felt body 24 and the elastic felt body 19, so that the black felt body 24 and the elastic felt body 19 are bonded together more safely and efficiently.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.12As shown, a marking mechanism 26 fixedly connected to the inner wall of the bonding box 1 is arranged between the rotating roller 1501 and the arc-shaped pressing plate 1503, and the marking mechanism 26 includes a fixed cylinder 2601 fixedly arranged on the inner wall of the bonding box 1 and located between the rotating roller 1501 and the arc-shaped pressing plate 1503, an extrusion spring 2603 is fixedly arranged on the inner side of the fixed cylinder 2601, a slide plate 2602 slidably connected to the inner side of the fixed cylinder 2601 is fixedly arranged at one end of the extrusion spring 2603, and a reset triangle block 2604 matched with the clearance is fixedly arranged on one side of the slide plate 2602, and the reset triangle block 2604 matched with the clearance is fixedly arranged on the one side of the slide plate 2602. One side of the triangular block 2604 is provided with an extrusion roller 2605 that rolls with the inner wall of the arc pressure plate 1503. The diameter of the extrusion roller 2605 is relatively small. When the extrusion roller 2605 squeezes the black felt body 24, it will leave an indentation on one side of the black felt body 24 for marking. In the present application, the central angle of each arc pressure plate 1503 is 115°, and the radius of each arc pressure plate 1503 is 0.5m. Therefore, the arc length of each arc pressure plate 1503 is 1m, so the gap between the three arc pressure plates 1503 is 1m, that is, the distance between the indentations left by each extrusion is 1m. Specifically, when in use, the radius corresponding to each arc-shaped pressing plate 1503 can be adjusted, so that the distance between the indentations left each time can be adjusted. When in use, when there is no mark (i.e., pressing mark), the extrusion roller 2605 will fit on the inner wall of the arc-shaped pressing plate 1503. At this time, the extrusion spring 2603 is in a compressed state. When the arc-shaped pressing plate 1503 rotates, it drives the extrusion roller 2605 to rotate at one end of the reset triangle block 2604. The three arc-shaped pressing plates 1503 rotate during the rotation process. When the gap between two adjacent arc-shaped pressure plates 1503 passes through the extrusion roller 2605, the extrusion roller 2605 slides into the gap between the two arc-shaped pressure plates 1503 under the elastic force of the extrusion spring 2603. During the sliding process, the extrusion roller 2605 will squeeze the edges of the black felt body 24 and the elastic felt body 19, leaving indentations on the edges of the black felt body 24, and the distance between each two indentations is 1m, which is convenient for subsequent personnel to cut the elastic felt body 19 of a specific length without the need for a ruler, thereby improving the convenience of subsequent use.

[0048] It should be noted that, when using the glue atomization spraying process of the glass fiber elastic felt, the second sealing door 29 is opened, and the unwinding elastic felt roller 20 is first placed on the upper side of the arc base 18, and then the positioning plate 501 is squeezed by the positioning spring 502, so that the positioning plate 501 can squeeze the unwinding elastic felt roller 20, so that the unwinding elastic felt roller 2 is fixed on the upper side of the arc base 18, and then a servo motor 402 drives the screw rod 403 to rotate, so that the threaded sleeve 404 on which the threaded sleeve is arranged can be lifted and lowered under the action of the guide rail 401, thereby driving the loading plate 3 on one side of the threaded sleeve 404 to lift and lower, so that the unwinding elastic felt roller 20 on the loading plate 3 can be raised. When the unwinding elastic felt roller 20 is raised to the unwinding position, the threaded sleeve 404 can be lifted and lowered. When the second servo motor 1606 is engaged with the support block 1606 on the winding mechanism 16, the electric telescopic rod 1603 drives the slide 1604 to slide inward, so that the support block 1606 on the upper side of the slide 1604 slides inward together with the second servo motor 1606, and the latch on one side of the support block 1606 is inserted into the two ends of the unwinding elastic felt roller 20, so that the unwinding elastic felt roller 20 can be fixed between the two support blocks 1606 on the unwinding mechanism 16, and the second servo motor 1606 drives the latch to rotate, which can drive the unwinding elastic felt roller 20 to rotate, and then the same operation is performed to fix the winding elastic felt roller 21 between the two support blocks 1606 on the winding mechanism 17, and then the black felt roller 23 is fixed on the feeding shaft 14 through the first sealing door 28. Then the elastic felt body 19 on the unwinding elastic felt roller 20 passes through the upper guide roller 6 and the side of the vertical plate 2 in turn, then passes through the lower guide roller 13, and is finally rolled up onto the winding elastic felt roller 21. Then the black felt body 24 on the black felt roller 23 passes through the upper side of the arc-shaped pressure plate 1503 and fits onto the surface of the elastic felt body 19. During the glue spraying process, the glue inside the glue box 807 is pumped into the glue inlet pipe 806 through the pump body 805, and then enters the inside of the collecting tube 801. The glue is pumped into the glue spraying tube 803 through a plurality of hoses 802 on one side of the collecting tube 801, and finally the glue is atomized and sprayed out through a plurality of atomizing glue spraying heads 804 on one side of the glue spraying tube 803, so that the atomized glue is sprayed onto the elastic felt body on one side of the vertical plate 2. The surface of the body 19 is smoothed by scraping glue, and the elastic felt body 19 moves downward, and the glue on the surface of the elastic felt body 19 can be smoothed and scraped off through the scraping opening at the upper end of the scraper 9. Finally, the second motor 1506 drives the rotating roller 1501 to rotate counterclockwise, so that the three arc-shaped pressing plates 1503 outside the rotating roller 1501 can rotate counterclockwise, so that the black felt roller 23 on one side of the arc-shaped pressing plate 1503 is pressed and fitted on the surface of the black felt roller 23, and the movable rod 1502 on one side of the arc-shaped pressing plate 1503 and the pressing spring 1505 at the lower end of each movable rod 1501 can buffer the force of the arc-shaped pressing plate 1503 pressing the black felt body 24 on the elastic felt body 19, so that the pressing force increases slowly.Improve the lamination effect between the glue on the surface of the elastic felt body 19 and the black felt body 24. During the process of marking the length of the black felt roller 23, when the arc-shaped pressing plate 1503 rotates, it drives the squeezing roller 2605 to rotate at one end of the reset triangle block 2604. During the rotation of the three arc-shaped pressing plates 1503, when the gap between two adjacent arc-shaped pressing plates 1503 passes through the squeezing roller 2605, the squeezing roller 2605 slides into the gap between the two arc-shaped pressing plates 1503 under the elastic force of the squeezing spring 2603. During the sliding process, the squeezing roller 2605 squeezes the edge of the black felt body 24 and the elastic felt body 19, leaving an indentation on the edge of the black felt body 24. Since the arc length of the three arc-shaped pressing plates 1503 is 1m, the indentation distance on the surface of the black felt body 24 is 1m, which is convenient for subsequent personnel to cut the elastic felt body 19 of a specific length, thereby improving the convenience of using the elastic felt body 19.
