Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a glass fiber product coating device. Background Technology

[0002] Fiberglass products are various products made from fiberglass as the core raw material. They are high-performance inorganic non-metallic materials, widely used in industry, construction, and daily life due to their lightweight, high strength, insulation, heat insulation, and corrosion resistance. When transporting fiberglass products, they need to be packaged with film. The core purpose of this is to prevent dust and leakage, protect against moisture and maintain performance, and prevent punctures and ensure safety.

[0003] A packaging device for fiberglass production, with application publication number CN121822951A, includes a packaging assembly comprising a conveyor belt. A first support frame is fixed to the surface of the conveyor belt, a second support frame is fixed to one side of the first support frame, a servo motor is fixed to the top of the second support frame, a rotating component is fixed to the output end of the servo motor, and a packaging component is fixed to the inner wall of the rotating component. This invention eliminates the need for manual transfer of finished products after packaging, simplifies the operation process, reduces the labor intensity of workers, and ensures a smooth connection between packaging and transfer processes. Through gravity transmission, it automatically drives and replenishes the delivery structure according to the packaging progress, achieving automatic material feeding.

[0004] However, this packaging device has the following drawbacks in practical use: Existing packaging devices, when packaging fiberglass products using film (mainly thin film), require rotating the unwound film around the fiberglass product to adhere it to the outside, wrapping the product layer by layer. However, in actual operation, this method generates a large amount of static electricity during the unwinding and transporting of the film. This static electricity causes the unwound film to attract dust from the working environment, contaminating both the film and the fiberglass product, leaving dirt and impurities that affect the product's quality. Furthermore, the static-filled unwound film interferes with the subsequent heat-sealing process after packaging, potentially resulting in an insecure or uneven seal. Moreover, the large amount of static electricity can cause the film to spontaneously combust, compromising the safety of the entire packaging operation. Traditional methods of packaging fiberglass products involve rotating the fiberglass product on a pallet while simultaneously unwinding and wrapping the film around it. However, in practice, this method requires the fiberglass product to rotate and remain in contact with the film. The rotating fiberglass product is prone to loosening and falling off, resulting in low packaging safety. Summary of the Invention

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In the fiberglass product wrapping device, when packaging fiberglass products using unwound film, the rotational force driving the unwound film is transmitted via belt and gears, causing a gas piston to reciprocate inside a gas tank. This continuously compresses the gas, allowing it to be continuously pressurized and transmitted to the inside of the ion bar shell. The gas mixes with the positive and negative ions generated inside the ion bar shell, which are then sprayed onto the film outside the film winding sleeve. This process removes surface static charge from the unwound film, preventing it from attracting dust and other impurities during unwound and packaging, thus ensuring the cleanliness and quality of the fiberglass product. Furthermore, eliminating surface static charge ensures a more secure and even seal during subsequent heat sealing, improving the safety and efficiency of the entire fiberglass product packaging process. It should be noted that air is ionized into a large number of positively and negatively charged ion clusters through high-voltage corona discharge, and then compressed air is used to blow these ions toward the surface of the thin film. When the ions encounter the static charge accumulated on the thin film, charge neutralization occurs, thereby eliminating static electricity; 2. In the glass fiber product wrapping device, when packaging glass fiber products with unwound film, the rotational force driving the film during unwinding can also be transmitted via belt and lead screw to rotate and vibrate one side of the unwound film layer, while the other side experiences lifting and sliding friction. This keeps the unwound film layer in a vibrating state, reducing the probability of dust and other impurities, as well as static charges, adsorbing onto the film surface. Simultaneously, it can guide the unwound film, ensuring a certain indirection between the unwound film and the film winding sleeve as the film is unwound from the outside of the film winding sleeve, resulting in more stable unwinding. 3. In the fiberglass product wrapping device, the efficiency of fiberglass product packaging can be effectively improved by stacking fiberglass products, transporting the stacked fiberglass products using a roller feeding device, pressing and fixing the fiberglass products in the transport state, automatically rotating and packaging the fiberglass products in the pressed and fixed state, and automatically unloading the packaged fiberglass products. At the same time, the packaged fiberglass products will not fall off due to the force and tension during film packaging, making the fiberglass product packaging operation safer.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0021] Please see Figures 1-18 A glass fiber product coating device includes a roller feeding device 10; a gantry frame 20 disposed outside the roller feeding device 10; a telescopic arm pressing device 30 installed at the bottom center of the gantry frame 20; and an automatic coating and cleaning device 40 installed outside the telescopic arm pressing device 30. The automatic coating and cleaning device 40 performs rotary packaging processing on the conveyed glass fiber. The automatic coating and cleaning device 40 includes: a rotating support structure 401 installed inside the gantry frame 20 and located outside the telescopic arm pressing device 30; and a vertical lifting structure 402 installed inside the rotating support structure 401. A counterweight 403 is installed on the side of 02, and an unwinding and wrapping structure 404 is installed on the side of another vertical lifting structure 402; a vertical rotating rod 405 is connected to the unwinding and wrapping structure 404; a gas pressurizing structure 406 is connected to the vertical rotating rod 405, the gas pressurizing structure 406 is installed on the outside of the unwinding and wrapping structure 404, and an ion electrostatic removal structure 407 extending into the interior of the unwinding and wrapping structure 404 is connected to its side; a film unwinding and cleaning structure 408 is connected to the vertical rotating rod 405 via a synchronous pulley, and the film unwinding and cleaning structure 408 is located on the side of the ion electrostatic removal structure 407.

[0022] The working principle is as follows: When packaging fiberglass products, the stacked fiberglass products are placed on top of the roller feeding device 10. The roller feeding device 10 moves the fiberglass products to the bottom of the gantry frame 20, and the telescopic arm pressing device 30 installed at the bottom of the gantry frame 20 presses down and fixes the fiberglass products located on top of the roller feeding device 10, preventing displacement of the fiberglass products due to the tension of the film during packaging. Simultaneously, when packaging fiberglass products with film, the vertical lifting structure 402 drives the unwinding and wrapping structure 404 to move up and down, achieving continuous packaging of the outer surface of the fiberglass products. The rotating support structure 401 can drive the unwinding and wrapping structure 404 to rotate around the fiberglass products, realizing automated packaging operations. When packaging fiberglass products with the unwinding and wrapping structure 404, the vertical rotating rod 405 can be continuously rotated. At this time, the rotation of the vertical rotating rod 405 will drive the gas pressurization structure 406 to operate, squeezing the gas into the interior of the ion electrostatic removal structure 407. The positive and negative ions generated by the ion electrostatic removal structure 407 will neutralize the static charge accumulated on the film surface, preventing the accumulation of static charge on the film surface from affecting the safety of the film when packaging glass fiber products. It also makes it less likely to adsorb dust and impurities in the working environment, avoiding problems such as contamination of glass fiber products in the packaging state.

[0023] It should be noted that when the vertical rotating rod 405 rotates, it can drive the film unwinding and cleaning structure 408 to operate, guide and vibrate the film in the unwinding state, and remove static charge and dust and other impurities from the film surface as much as possible.

[0024] For details, please refer to the following: Figure 5 , Figure 6 and Figure 7The telescopic boom lowering device 30 includes an intermediate support body 301, which is installed at the center of the top of the gantry frame 20. A first drive source 302 is installed on the side of the intermediate support body 301. The output end of the first drive source 302 is connected to a drive rod 303 that passes through the intermediate support body 301. A rotating disk 304 is rotatably connected to the side of the intermediate support body 301 and installed on the outside of the drive rod 303. A connecting arm 305 is rotatably connected to the eccentric part of the side of the rotating disk 304. A sliding block 306 is rotatably connected to the bottom of the connecting arm 305. The sliding block 306 is slidably set. Inside the intermediate support body 301; a telescopic arm 307, the center of which is rotatably mounted on the outside of the sliding block 306; multiple telescopic arms 307 are provided, and the multiple telescopic arms 307 are staggered; the end portions of two telescopic arms 307 are rotatably connected by a rotating guide block 308; a mounting arm 309, which is rotatably connected to the end of the telescopic arm 307 by the rotating guide block 308; the mounting arm 309 is rotatably connected to the side of the side protrusion 3010, which is mounted on the side of the intermediate support body 301 and located at the bottom of the rotating disk 304.

[0025] In this design, the bottom ends of the two telescopic arms 307 located at the bottom are rotatably connected to movable seats 3071. The movable seats 3071 are installed on the top of the upper mounting plate 3072 by screws. The bottom of the upper mounting plate 3072 is movably connected to a lower pressure metal plate 3073. The angle between the lower pressure metal plate 3073 and the upper mounting plate 3072 is connected by a vertical rod 3074. A buffer spring 3075 is sleeved on the outside of the vertical rod 3074 between the lower pressure metal plate 3073 and the upper mounting plate 3072.

[0026] In the glass fiber product coating device of the present invention, when the glass fiber product is pressed and positioned, the first drive source 302 is activated, driving the drive rod 303 connected to the output end of the first drive source 302 to rotate, and driving the rotating disk 304 connected to the drive rod 303 to rotate. When the rotating disk 304 rotates, the connecting arm 305 rotatably connected to its eccentric side will drive the sliding block 306 to move up and down inside the intermediate support body 301, driving the telescopic arm 307 rotatably connected to the outside of the sliding block 306 to move (the telescopic arm 307 in the crossed state moves and deforms), driving the upper mounting plate 3072 rotatably connected to the bottom of the telescopic arm 307 to move up and down. The design of the mounting arm 309 guides the rotational movement of several telescopic arms 307, ensuring the stability of the telescopic arms 307 during movement; the up and down movement of the upper mounting plate 3072 and the pressing metal plate 3073 can press and fix the glass fiber product.

[0027] When the fiberglass product comes into contact with the pressure plate 3073, it will compress the buffer spring 3075 on the top of the pressure plate 3073. The buffer spring 3075 absorbs the force generated by direct contact, thus preventing the pressure plate 3073 from damaging the fiberglass product.

[0028] For details, please refer to the following: Figure 4 The rotating support structure 401 includes a rotating drive source 4011, which is installed at the center of the top of the gantry 20. The output end of the rotating drive source 4011 is connected to a rotating seat 4012. A U-shaped metal frame 4013 is installed at the bottom of the rotating seat 4012. A telescopic arm pressing device 30 is movably arranged at the center of the interior of the rotating seat 4012. A vertical lifting structure 402 is installed inside the U-shaped metal frame 4013.

[0029] In the glass fiber product wrapping device of the present invention, when the glass fiber product is packaged, the rotary drive source 4011 is started to operate, which drives the rotary seat 4012 connected to the output end of the rotary drive source 4011 to rotate, and drives the U-shaped metal frame 4013 installed at the bottom of the rotary seat 4012 to rotate, so that the unwinding wrapping structure 404 rotates on the outside of the glass fiber product to package the glass fiber product.

[0030] For details, please refer to the following: Figure 4 , Figure 8 and Figure 9 The vertical lifting structure 402 includes a lifting drive source 4021, which is installed on the side of the concave metal frame 4013. The output end of the lifting drive source 4021 is connected to a first bevel gear 4022, and the side of the first bevel gear 4022 is meshed with a second bevel gear 4023. Both the first bevel gear 4022 and the second bevel gear 4023 are movably disposed within the inner top of the concave metal frame 4013. A vertical reciprocating screw 4024 is also included. The rod 4024 is connected to the second bevel gear 4023 and is rotatably disposed inside the concave metal frame 4013. The outer side of the vertical reciprocating screw 4024 is connected to a vertical lifting slide 4025 by ball bearings. The vertical lifting slide 4025 is slidably connected inside the concave metal frame 4013. A counterweight 403 is installed on the side of one vertical lifting slide 4025 by screws, and an unwinding and wrapping structure 404 is installed on the side of the other vertical lifting slide 4025 by screws.

[0031] In the glass fiber product coating apparatus of the present invention, when the glass fiber product is packaged, the lifting drive source 4021 is activated to operate, driving the first bevel gear 4022 connected to the output end of the lifting drive source 4021 to rotate, causing the second bevel gear 4023 meshing with the first bevel gear 4022 to rotate. When the second bevel gear 4023 rotates, the vertical reciprocating screw 4024 connected to the second bevel gear 4023 will rotate, driving the vertical lifting slide 4025 connected to the outside of the vertical reciprocating screw 4024 via ball bearings to move up and down, adjusting the position and height of the unwinding coating structure 404, and realizing the coating operation of the entire glass fiber product.

[0032] It should be noted that the design of the counterweight 403 can provide counterweight to the unwinding wrapping structure 404 in the unwinding state, ensuring the stability of the device during operation.

[0033] For details, please refer to the following: Figure 10 and Figure 11 The unwinding and wrapping structure 404 includes a mounting bracket 4041, which is screwed to the side of a vertical lifting slide 4025. A movable rod 4042 is rotatably connected to one side of the mounting bracket 4041, and a film winding sleeve 4043 is fixedly mounted on the outside of the movable rod 4042. An arc-shaped side pressure plate 4044 is movably disposed on one side of the film winding sleeve 4043. A guide block 4045 is mounted on the back of the arc-shaped side pressure plate 4044 and slidably connected inside the mounting bracket 4041. A support spring 4046 is mounted at the bottom of the guide block 4045. 046 is connected to the side of the vertical lifting slide 4025; the first synchronous belt 4047 is connected to the outer side of the top of the movable rod 4042 through the synchronous pulley, the first synchronous belt 4047 is movably disposed in the inner top of the mounting bracket 4041, and the inner side of the first synchronous belt 4047 is connected to the vertical rotating rod 405 through the synchronous pulley. Among them, the outer side of the mounting bracket 4041 is equipped with a gas pressurization structure 406, the inner wall of the mounting bracket 4041 is equipped with an ion electrostatic removal structure 407, and the film unwinding cleaning structure 408 is movably disposed in the inner side of the mounting bracket 4041 and is located on the side of the film winding sleeve 4043.

[0034] In the glass fiber product wrapping device of the present invention, when the glass fiber product is packaged, the film winding sleeve 4043 continuously rotates to unwind the film. The rotational force during unwinding drives the movable rod 4042 installed inside to rotate, which in turn drives the first synchronous belt 4047 connected to the top outer side of the movable rod 4042 via a synchronous pulley. The operation of the first synchronous belt 4047, in turn, drives the vertical rotating rod 405 connected to its inner side via a synchronous pulley to rotate.

[0035] When the film on the outside of the film take-up sleeve 4043 is unwound, the diameter of the film take-up sleeve 4043 will decrease. At this time, the design of the arc-shaped side pressure plate 4044 on the outside of the film take-up sleeve 4043 can perform side pressure treatment on the film in the unwound state, so as to prevent the film from falling off the outside of the film take-up sleeve 4043 due to the change of tension. At the same time, the arc-shaped side pressure plate 4044 connected by the support spring 4046 can continuously squeeze the film take-up sleeve 4043 as it shrinks, so as to ensure the stability of the film during unwinding.

[0036] For details, please refer to the following: Figure 13 , Figure 14 , Figure 15 and Figure 16 The gas pressurization structure 406 includes a first bevel gear 4061 connected to a vertical rotating rod 405. A second bevel gear 4062 is meshed with the side of the first bevel gear 4061. A rotating rod 4063 extending outward is mounted on the side of the second bevel gear 4062, extending to the outside of the mounting bracket 4041. A second synchronous belt 4064 is connected to the outside of the rotating rod 4063 via a synchronous pulley. A horizontal reciprocating screw 4065 is connected to the inside of the second synchronous belt 4064 via a synchronous pulley. The horizontal reciprocating screw 4065 is rotatably disposed inside the gas tank 4066, which is mounted inside the mounting bracket 4041. On the outside of 1, the middle part of the gas tank 4066 is set as a gas sealed space; a horizontal slider 4067 is connected to the outside of the horizontal reciprocating screw 4065 by ball bearings and is slidably connected to the inner top of the gas tank 4066. A linear rod 4068 is installed at the eccentric part inside the horizontal slider 4067. A gas piston 4069 is connected to the bottom of the linear rod 4068. The gas piston 4069 is movably set in the middle of the gas tank 4066. An intermediate rotating rod 40691 is provided through the center of the gas piston 4069. The intermediate rotating rod 40691 is connected to the horizontal reciprocating screw 4065. An exhaust port 40661 connected to the gas sealed space is installed at the inner bottom of the gas tank 4066.

[0037] In the glass fiber coating device of the present invention, when the vertical rotating rod 405 rotates, it drives the first bevel gear 4061 mounted on its outer side to rotate, causing the second bevel gear 4062 and the rotating rod 4063, which are meshed on the side of the first bevel gear 4061, to rotate. When the rotating rod 4063 rotates, the second synchronous belt 4064, which is connected to the synchronous pulley on its outer side, operates, causing the horizontal reciprocating screw 4065, which is connected to the synchronous pulley on the inner side of the second synchronous belt 4064, to rotate continuously.

[0038] When the horizontal reciprocating lead screw 4065 rotates continuously, the horizontal slider 4067 connected to it by ball bearings will drive the gas piston 4069 to extend and retract inside the gas tank 4066 via the linear rod 4068, continuously compressing the gas inside the gas tank 4066, so that the gas can be transmitted through the exhaust port 40661 to the inside of the ion electrostatic removal structure 407, disturbing the positive and negative ions generated inside the ion electrostatic removal structure 407.

[0039] For details, please refer to the following: Figure 16 The gas sealing space of the gas tank 4066 is connected to the outside of the circulation channel unit 40662. The gas sealing space of the gas tank 4066 is connected to the outside of the gas inlet 40663 located on the side of the circulation channel unit 40662. The bottom of the gas tank 4066 is equipped with a lower sealing pipe 40664. The bottom of the intermediate rotating rod 40691 is connected to an ion electrostatic removal structure 407, which is installed on the side of the lower sealing pipe 40664.

[0040] In the glass fiber product coating device of the present invention, gas is transmitted through the inlet 40663 to the gas sealing space inside the gas tank 4066 (the part located outside the gas piston 4069), the circulation channel unit 40662 drives the gas to move, and the port part of the circulation channel unit 40662 is equipped with a one-way valve structure to restrict the one-way movement of the gas.

[0041] For details, please refer to the following: Figure 17The ion electrostatic removal structure 407 includes an ion rod shell 4071, which is installed on the side of the lower sealing pipe 40664. A spiral guide rod 4072 is rotatably connected to the inner top of the ion rod shell 4071, and the spiral guide rod 4072 is connected to the intermediate rotating rod 40691. A side flow port 4073 for gas flow is opened on the inner top of the ion rod shell 4071, which transmits gas to the interior of the ion rod shell 4071. A high-voltage electrode unit 4074 is installed inside the ion rod shell 4071. The top of the high-voltage electrode unit 4074 is connected to a power supply unit 4075 via a cable. The power supply unit 4075 is installed on the inner top of the mounting bracket 4041. Two high-voltage electrode units 4074 are connected by a cable. An ion air valve 4076 is installed at the root of the ion rod shell 4071, and the ion rod shell 4071 is located on the side of the film winding sleeve 4043.

[0042] In the glass fiber coating apparatus of the present invention, the power supply unit 4075 transmits current to the interior of the high-voltage electrode unit 4074 via a cable, causing the high-voltage electrode unit 4074 to operate and generate a large number of positive and negative ions. The generated positive and negative ions are circulated by the airflow compressed into the ion bar shell 4071, and are directly projected unidirectionally onto the surface of the film winding sleeve 4043 through the ion air valve 4076, performing electrostatic removal on the film winding sleeve 4043 in the unwound state.

[0043] Pressurized airflow is transmitted to the interior of the ion rod shell 4071 through the side flow port 4073, and then to the outside of the high-voltage electrode unit 4074 through the side flow port 4073 inside the ion rod shell 4071, causing the positive and negative ions and gas on the outside of the high-voltage electrode unit 4074 to move; the rotation of the intermediate rotating rod 40691 will drive the spiral guide rod 4072 to rotate, and the rotation of the spiral guide rod 4072 will make the airflow transmission more uniform.

[0044] For details, please refer to the following: Figure 18The film unwinding and cleaning structure 408 includes a third synchronous belt 4081, which is connected to the outside of the vertical rotating rod 405 via a synchronous pulley. The third synchronous belt 4081 is movably disposed at the inner bottom of the mounting bracket 4041. A cam rotating rod 4082 is connected to the inner side of the third synchronous belt 4081 via a synchronous pulley. A conical stop 4083 is screwed onto the inner center of the cam rotating rod 4082, and the conical stop 4083 extends to the outside of the cam rotating rod 4082. An external reciprocating lead screw 408... 4. An external reciprocating screw 4084 is installed on the outer side of the top of the cam rotating rod 4082. An external slider 4085 is connected to the outer side of the external reciprocating screw 4084 via ball bearings.

The cleaning rod 4086 is located on the side of the cam rotating rod 4082. The cleaning rod 4086 is slidably connected to the side of the mounting bracket 4041. A return spring 4087 is installed on the outer side of the bottom of the cleaning rod 4086.

[0045] In the glass fiber coating apparatus of the present invention, when the vertical rotating rod 405 rotates, the third synchronous belt 4081, connected to its outer bottom via a synchronous pulley, operates, driving the cam rotating rod 4082, connected to its inner side via a synchronous pulley, to rotate. When the cam rotating rod 4082 rotates, it drives the conical stop 4083 installed inside the cam rotating rod 4082 to move, intermittently and continuously vibrating the unwound film to remove static charge and impurities such as dust from the film surface.

[0046] When the cam rotor 4082 rotates, the external reciprocating lead screw 4084 mounted on its top outer side rotates, driving the external slider 4085 and cleaning rod 4086, which are connected by ball bearings, to move up and down. At this time, the film in the unwound state, which is in contact with the side of the cleaning rod 4086, slides through the inner notch 40861 on the side of the cleaning rod 4086, causing the unwound film to vibrate and remove impurities and static charge from the film surface.
