Description

Technical Field

[0001] This utility model relates to the field of glass fiber mat surface treatment technology, and in particular to an electrostatic adsorption device for glass fiber mat surface treatment. Background Technology

[0002] In the industrial production of fiberglass mat, surface treatment is a key step in improving its performance (such as enhancing resin wettability and improving mechanical strength). Among these methods, electrostatic dust removal technology is widely used to remove dust, fiber debris, and other impurities adhering to the surface of fiberglass mat due to its non-contact and high-efficiency characteristics.

[0003] In existing technologies, electrostatic adsorption devices typically generate charged particles by ionizing air and spray them onto the surface of fiberglass mat through fixedly arranged nozzles to neutralize the static electricity on the fiberglass mat. However, the spray paths of the fixed nozzles are linearly oriented, which is difficult to adapt to the complex three-dimensional surface structure of the fiberglass mat (such as wrinkles and pores). This results in insufficient adsorption energy in some areas (such as fiber intersections and edge areas). Furthermore, due to the limited overlap of paths between adjacent nozzles, "blind zones" are formed that are not covered by the ionized airflow, and the electrostatic neutralization effect shows significant regional differences. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide an electrostatic adsorption device for surface treatment of fiberglass mat, so as to solve the technical problem that the electrostatic neutralization effect is significantly different in different regions due to the current fixed arrangement of spray holes spraying onto the surface of fiberglass mat.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An electrostatic adsorption device for surface treatment of fiberglass mat includes a U-shaped frame and a fiberglass mat body. A crossbeam is fixed to the middle of the top of the U-shaped frame. An ion air assembly is installed on both sides of the inside of the U-shaped frame, and the two ion air assemblies in the same group are arranged in a opposite state. At the same time, the nozzles of the ion air assemblies on both sides are arranged obliquely inward. A dust collection assembly is installed at the middle of the bottom of the inner wall of the U-shaped frame and at the bottom of the crossbeam. A toggle assembly is installed inside the U-shaped frame and in front of the movable end of the ion air assembly, and the two driving ends of the toggle assembly face the ion air assemblies on both sides.

[0008] The ion wind assembly includes a fixing strip plate fixed inside a U-shaped frame, an L-shaped plate slidably mounted on the bottom of the fixing strip plate, and an ion wind knife fixed in the inner cavity of the L-shaped plate.

[0009] As an improved technical solution, a pressure roller is rotatably installed inside the U-shaped frame and at the inlet end of the fiberglass felt body. The fiberglass felt body passes between the two ion wind components and is located below the pressure roller.

[0010] As an improved technical solution, guide rails are fixed on both sides of the bottom of the fixed strip, and sliders that slide on the guide rails are fixed on both sides of the lateral end of the L-shaped plate.

[0011] As an improved technical solution, two rod blocks are fixed at the bottom of the fixed strip plate, and a positioning rod is fixedly connected between the two rod blocks. A sliding hole block is installed at the top of the L-shaped plate between the two rod blocks, and the sliding hole block is slidably connected to the positioning rod through a sliding hole on it. A spring is sleeved on the positioning rod between the sliding hole block and the opposite surface of the rod block.

[0012] As an improved technical solution, the actuation assembly includes a pad installed inside the U-shaped frame and a dual-axis motor installed on the top of the pad. Actuation bars are installed on both drive shafts of the dual-axis motor, and the two protruding ends of the actuation bars face the vertical ends of the two L-shaped plates on the same side. The outer end of the drive shaft of the dual-axis motor is rotatably connected to a shaft frame through a bearing.

[0013] As an improved technical solution, both ends of the actuating bar near the L-shaped plate are fixed with universal balls, and the rolling end of the universal balls rolls at the vertical end of the L-shaped plate.

[0014] As an improved technical solution, the dust collection assembly includes two mounting brackets and a dust collection chamber fixed between the two mounting brackets. A dust feeding pipe is fixedly installed at the dust outlet end of the dust collection chamber, and the dust feeding pipe is fixedly connected to the dust inlet end of a dust removal fan at the end away from the dust collection chamber.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the reciprocating rotation of the toggle bar driven by the dual-axis motor can cause the ion air knife to be in a horizontal reciprocating state, which not only expands the spray range of the ion air knife, but also avoids the blind zone of two adjacent fixed nozzles in the traditional way. Furthermore, one toggle component can simultaneously drive four ion air components to adjust their horizontal position, effectively reducing the production and use costs.

[0017] 2. This utility model forms a three-dimensional electrostatic field coverage through the symmetrical layout of the upper and lower ion wind components, effectively eliminating the edge effect caused by traditional single-sided treatment. At the same time, the ion wind components are in a horizontally reciprocating state, which expands the area area of ​​the ion wind components during spraying and avoids the existence of blind spots between two adjacent nozzles. Furthermore, the nozzle ends of the ion wind components on both sides are set inward, so the ionized air is more concentrated on the inner side, improving the contact effect and contact area with the fiberglass felt body. The electrostatic neutralization effect of the fiberglass felt body is more uniform and comprehensive, resulting in excellent dust removal effect. Attached Figure Description

[0030] like Figures 1 to 5 As shown in the figure, this embodiment provides an electrostatic adsorption device for surface treatment of fiberglass mat. This electrostatic adsorption device for surface treatment of fiberglass mat includes a U-shaped frame 1 and a fiberglass mat body 3. A crossbeam 5 is fixed in the middle of the top of the U-shaped frame 1. A set of ion wind components 6 are installed on both sides inside the U-shaped frame 1, and the two ion wind components 6 in the same set are arranged in a relative position. At the same time, the nozzles of the ion wind components 6 on both sides are arranged obliquely inward. A dust collection component 4 is installed in the middle of the bottom of the inner wall of the U-shaped frame 1 and the bottom of the crossbeam 5. A toggle component 7 is installed inside the U-shaped frame 1 and in front of the movable end of the ion wind component 6. The two driving ends of the toggle component 7 are directly opposite the ion wind components 6 on both sides. One toggle component 7 can drive four ion wind components 6 to adjust their horizontal position at the same time, which effectively reduces the production and use costs.

[0031] The ion wind assembly 6 includes a fixing strip 61 fixed inside the U-shaped frame 1, an L-shaped plate 64 slidably mounted on the bottom of the fixing strip 61, and an ion wind knife 65 fixed in the inner cavity of the L-shaped plate 64.

[0032] The symmetrical layout of the ion air components 6 creates a three-dimensional electrostatic field coverage, effectively eliminating the edge effect caused by traditional single-sided treatment. At the same time, the ion air components 6 are in a horizontally reciprocating state, which expands the area area when the ion air components 6 sprays and avoids the existence of blind spots between two adjacent nozzles. Furthermore, the nozzle ends of the ion air components 6 on both sides are set to face inward, so the ionized air is more concentrated on the inner side, which improves the contact effect and contact area with the fiberglass felt body 3. The electrostatic neutralization effect of the fiberglass felt body 3 is more uniform and comprehensive, resulting in excellent dust removal effect.

[0033] like Figure 1 As shown in this embodiment, a pressure roller 2 is rotatably installed inside the U-shaped frame 1 at the inlet end of the fiberglass felt body 3. The fiberglass felt body 3 passes between the two ion air components 6 and is located below the pressure roller 2. The pressure roller 2 limits the position of the fiberglass felt body 3, which helps to keep the fiberglass felt body 3 at the center of the opposite side of the two ion air components 6 in the same group. This ensures that the distance between the fiberglass felt body 3 and the upper and lower ion air components 6 is almost the same, thereby improving the dust removal effect on the fiberglass felt body 3.

[0034] like Figure 2 As shown, in this embodiment, guide rails 63 are fixed on both sides of the bottom of the fixed strip 61, and sliders 62 that slide on the guide rails 63 are fixed on both sides of the horizontal end of the L-shaped plate 64.

[0035] like Figures 2 to 3 As shown in the figure, in this embodiment, two rod blocks 69 are fixed at the bottom of the fixed strip plate 61, and a positioning rod 67 is fixedly connected between the two rod blocks 69. A sliding hole block 66 is installed on the top of the L-shaped plate 64 between the two rod blocks 69, and the sliding hole block 66 is slidably connected to the positioning rod 67 through the sliding hole on it. A spring 68 is sleeved on the positioning rod 67 between the opposite surfaces of the sliding hole block 66 and the rod block 69. The dual-axis motor 71 drives the reciprocating rotation of the actuating strip 72, which can cause the ion air knife 65 to be in a horizontal reciprocating state, which not only expands the spray range of the ion air knife 65, but also avoids the blind zone of two adjacent fixed nozzles in the traditional way.

[0036] like Figures 4 to 5 As shown in the figure, in this embodiment, the actuating assembly 7 includes a pad installed inside the U-shaped frame 1 and a dual-axis motor 71 installed on the top of the pad. Actuating bars 72 are installed on both drive shafts of the dual-axis motor 71, and the two protruding ends of the actuating bars 72 are directly opposite the vertical ends of the two L-shaped plates 64 on the same side. The outer end of the drive shaft of the dual-axis motor 71 is rotatably connected to a shaft bracket 74 through a bearing, and the shaft bracket 74 is fixed inside the U-shaped frame 1.

[0037] like Figures 4 to 5 As shown in the figure, in this embodiment, both ends of the toggle bar 72 near the L-shaped plate 64 are fixed with universal balls 73, and the rolling end of the universal balls 73 rolls at the vertical end of the L-shaped plate 64. The arrangement of the universal balls 73 makes the contact between them and the L-shaped plate 64 roll away, reducing the coefficient of friction when they are in contact, thereby improving their smoothness.

[0038] like Figure 1 As shown, in this embodiment, the dust collection assembly 4 includes two mounting brackets and a dust collection chamber 41 fixed between the two mounting brackets. A dust delivery pipe 42 is fixedly installed at the dust outlet end of the dust collection chamber 41, and the dust delivery pipe 42 passes through the U-shaped frame 1 and is located outside the U-shaped frame 1. The end of the dust delivery pipe 42 away from the dust collection chamber 41 is fixedly connected to the dust inlet end of the dust removal fan, and a dust removal bag is fixed at the dust removal end of the dust collection chamber 41.

[0039] When in use, the fiberglass felt body 3 passes between the two ion wind components 6 and simultaneously passes between the dust inlet ends of the two dust collection components 4.

[0040] When the fiberglass mat body 3 passes through the interior of the ion air assembly 6, the ion air knife 65 sprays ionized air onto the outer wall of the fiberglass mat body 3. At the same time, the dual-axis motor 71 drives the actuating bar 72 to rotate alternately in both forward and reverse directions. When the actuating bar 72 rotates, the end corner of the actuating bar 72 will abut against the vertical end of the L-shaped plate 64. When the actuating bar 72 moves towards the rear end of the L-shaped plate 64, it will cause the L-shaped plate 64 to drive the ion air knife 65 to move backward and compress the spring 68 through the sliding hole block 66. When the actuating bar 72 releases from the contact with the L-shaped plate 64, under the elastic reset action of the spring 68, the ion air knife 65 will gradually reset forward, causing the ion air knife 65 to be in a horizontal reciprocating state, thus expanding the spray range of the ion air knife 65.

[0041] When the ionized air is sprayed onto the fiberglass felt body 3, the dust removal fan is turned on and, under its negative pressure, the dust is drawn from the pressure roller 2 and enters the dust collection chamber 41. Guided by the dust conveying pipe 42, the dust is finally stored in the dust collection bag.

[0042] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
