Description

Technical Field

[0001] The present invention belongs to the field of fluorocarbon coating production, and particularly relates to a filling device for fluorocarbon coating for photovoltaic PET film. Background Art

[0002] PET film is a packaging film with relatively comprehensive properties. It has good transparency and gloss; has good airtightness and fragrance retention, medium moisture resistance, and the moisture permeability decreases at low temperatures. The mechanical properties of PET film are excellent, and its strength and toughness are the best among all thermoplastic plastics. It is usually used in photovoltaic products, and a layer of fluorocarbon coating is applied to the photovoltaic PET film to increase the antioxidant ability. Fluorocarbon coatings are generally stored in tanks for convenient transportation by personnel. Currently, fluorocarbon coatings are filled into barrels through a filling method.

[0003] During the barrel filling process, a filling machine is required. The filling machines on the market currently use filling machines for filling, and the storage containers are cleaned, dried, and other steps before filling. This may cause problems such as deformation and loss of the sealing port and barrel body deformation during filling, resulting in leakage after filling. This will not only cause material waste and increased costs, but also may cause raw material leakage, pollution of the equipment, and the need for cleaning, which affects the filling efficiency.

[0004] Now a filling device for fluorocarbon coating for photovoltaic PET film is provided to solve the above problems. Summary of the Invention

[0034] Embodiment:

[0035] As Figures 1-9 shown, a filling device for fluorocarbon coating of PET film for photovoltaic use includes a filling device 8 and a mounting seat 4 located below the filling device 8;

[0036] A frame 2 is installed on the outside of the mounting base 4. The frame 2 is used to fixedly install the whole, and at the same time facilitate the installation and fixation of other devices. A turntable 404 is arranged inside the mounting base 4. The turntable 404 can rotate the clamping device 10 at the top. Driven by the clamping device 10, the barrel body at the top rotates, which is convenient for inspecting the barrel body. An installation frame 3 is fixedly installed on the inner side of the frame 2. The installation frame 3 is provided with a cross bar at the bottom, which can be used to install the filling device 8 at the bottom. At the same time, it can also facilitate the filling device 8 to slide in the installation frame 3 and adjust its position following the bottom mounting base 4. Four groups of filling devices 8 are movably installed at the bottom of the installation frame 3. One side of each of the four groups of filling devices 8 is fixed to the turntable 404 through a connecting movable rod 403. The connecting movable rod 403 can stretch up and down by itself while being used for connection, following the movement of the filling device 8 to avoid affecting the filling device 8. A clamping device 10 is installed on the top of the mounting base 4. The clamping device 10 can clamp the barrel body. Through special design inside, it can clamp by rotating at the same time, which is simpler and lower in cost compared with the traditional clamping mechanism. An edge detector 7 is installed on one side wall of the turntable 404 through a fixed frame. The edge detector 7 detects the change of the barrel wall edge through the change of the internal sliding resistor 703. By comparing with the preset change, it can understand whether the barrel wall has changed and judge whether there is a problem of barrel wall deformation. The edge detector 7 can detect the edge of the device to avoid the situation of barrel body deformation. At the same time, it can also eliminate some attachments in the barrel body to improve the aesthetics. A cleaning component 11 is installed on the other side wall of the turntable 404 through a fixed frame. The cleaning component 11 can remove the sundries in the device through the effect of dust suction, avoiding too much dust entering the device during the operation of the equipment, thus affecting the normal sales of the device. Rollers 401 are arranged on both sides of the turntable 404 and are used in cooperation with the mounting base 4. The rollers 401 drive the turntable 404 to rotate integrally in the mounting base 4. A motor 402 is installed at the bottom of the turntable 404. The motor 402 is a part of the turntable 404 structure. Driven by the motor 402, the whole can be driven to rotate;

[0037] A feeder 802 is arranged at the top of the filling device 8. The feeder 802 can send the material into the bottom discharge chute 806, and the material is sent into the bottom filling barrel through the discharge chute 806. A cylinder 801 is installed at the top of the feeder 802. The cylinder 801 controls the telescopic movement of the bottom feeding shaft 804 through the equipment. Driven by the telescopic movement of the feeding shaft 804, the sealing ring 805 as a whole moves to complete the loading and unloading of the material. A feeding pipe 803 is arranged inside the filling device 8. The feeding shaft 804 penetrates through the inside of the feeding pipe 803. The feeding shaft 804 drives the device to inject material through its own telescopic movement. A sealing ring 805 is installed at the output end of the feeding shaft 804. The sealing ring 805 seals the whole equipment. A discharge chute 806 which is used in cooperation with the sealing ring 805 is arranged inside the filling device 8. A cover plate 9 is installed at the bottom of the filling device 8. The cover plate 9 covers the barrel to avoid the falling of dust and other sundries;

[0038] Inside the cover plate 9, there is a protective case 902. A rubber cushion layer 903 is movably installed on the inner side of the protective case 902. The rubber cushion layer 903 improves the fitting degree between the device and the barrel body, avoiding the problem of raw material leakage. A pressure-sensitive sensing belt 901 is installed on one side wall of the rubber cushion layer 903. The pressure-sensitive sensing belt 901 can contact the barrel mouth. By rotating the barrel body, the change in the resistance in the pressure-sensitive sensing belt 901 is observed to detect the bottle mouth and confirm whether there is a notch problem, avoiding the problem of leakage after filling.

[0039] Inside the clamp 10, there is a servo motor 1002. The servo motor 1002 drives the threaded rod 1003 to rotate by rotating. While the threaded rod 1003 rotates, it can drive the overall movement of the limit block 1001. The barrel body is fixed by the movement of the limit block 1001. And two groups of threaded rods 1003 are installed at the output end of the servo motor 1002. The thread directions of the two groups of threaded rods 1003 are opposite. By rotating the servo motor 1002 in the same direction or in the opposite direction, the tightening or loosening of the two groups of limit blocks 1001 can be completed. The limit blocks 1001 are installed on the outer sides of the two groups of threaded rods through movable sleeves. Threads matching the two groups of threaded rods 1003 are respectively arranged inside the two movable sleeves. The output end of the servo motor 1002 is connected to the two groups of threaded rods 1003 by a vertical transmission structure.

[0040] Inside the edge detector 7, sleeves 702 are distributed in a matrix. The sleeves 702 are small in volume and are distributed in a matrix in the edge detector 7 for adapting to different barrel bodies and increasing the application range of the device. One end of the sleeve 702 is installed with a movable block 701 extending out of the sleeve 702. The movable block 701 can expand and contract in the sleeve 702 to complete the movement. A spring 704 used in cooperation with the movable block 701 is placed inside the sleeve 702. The spring 704 can apply pressure to the movable block 701 to keep contacting the movable block 701 all the time. A sliding resistor 703 is fixedly installed inside the spring 704. The sliding resistor 703 detects the change in the position of the movable block 701 through the change in resistance to understand information such as the arc edge of the barrel body. And the sliding end of the sliding resistor 703 is fixedly connected to the movable block 701.

[0041] One end of the pressurizer 6 is connected to the feeder 1 through a connecting pipe 601. A rotating rod 603 is rotatably installed inside the pressurizer 6, which can drive the pressure plate 602 to rotate by rotation. The rotation of the pressure plate 602 will extrude the raw materials. Through this extrusion design, only the rotation speed needs to be controlled to control the discharging speed. The outside of the rotating rod 603 is wrapped with the pressure plate 602. One end of the pressurizer 6 away from the connecting pipe 601 is installed with a rotating motor 604, and the rotating motor 604 drives the overall rotation of the pressure plate 602 by rotation, and the output end of the rotating motor 604 is connected to the rotating rod 603;

[0042] The cleaning assembly 11 is provided with an electric telescopic rod 1108. The electric telescopic rod 1108 can adjust the position of the vacuum cleaner 1103 by telescoping to comprehensively clean the impurities inside the device. The top of the electric telescopic rod 1108 is installed with a rotating shaft 1106. The rotating shaft 1106 can drive the internal gear seat 1105 to rotate by rotation of the rotating shaft. When the gear seat 1105 rotates, it will drive the rotating rod 1102 installed on it to rotate, adjusting the position of the vacuum cleaner 1103 to avoid affecting filling. The top of the rotating shaft 1106 is installed with a gear seat 1105. The outside of the rotating shaft 1106 is movably installed with a rotating rod 1102. One end of the rotating rod 1102 is installed with an electric motor 1101, and the electric motor 1101 can drive the device to rotate. Through the rotation of the vacuum cleaner 1103, the dust in the barrel is cleaned to avoid affecting the filling quality. The output end of the electric motor 1101 is fixedly installed with a vacuum cleaner 1103, and the vacuum cleaner 1103 can quickly and effectively clean the dust. The output end of the electric motor 1101 is installed with a metal rod, and the metal rod drives the overall rotation of the one-way bearing 1107. When the one-way bearing 1107 rotates forward, it will drive the overall rotation of the gear seat 1105 through the worm and gear combination 1104. And the outside of the metal rod is installed with a one-way bearing 1107. When the metal rod rotates in the reverse direction, it will not drive the outside of the one-way bearing 1107 to rotate, so the worm and gear combination 1104 will not rotate and transmit power. At this time, when the vacuum cleaner 1103 rotates alone, it will suck the inner wall of the barrel to avoid affecting the filling quality. The outside of the one-way bearing 1107 is connected to the gear seat 1105 through the worm and gear combination 1104; Rubber hoses are installed at both ends of the vacuum cleaner 1103, and the vacuum cleaner 1103 is detachable, which is convenient for regularly cleaning the dust and other sundries remaining in the equipment to ensure the dust removal effect;

[0043] A material receiver 1 is fixedly installed on the top of the frame 2, and the material receiver 1 conveys the filling material. A raw material bin 5 is installed on one side of the top of the material receiver 1. The raw material bin 5 is used to store materials to facilitate the filling of the equipment. Four groups of pressurizers 6 are installed on one side of the material receiver 1. They are designed separately while reducing costs, and can pressurize different tanks. After the pressurization is completed, a flow meter is provided at the discharge end of each group of pressurizers 6, and the output end of the pressurizer 6 is connected to the feed end of the feeder 802 through a hose;

[0044] A feeder 802 is provided on the top of the filler 8. The feeder 802 is used to connect the raw material input device. A cylinder 801 is installed on the top of the feeder 802. The cylinder 801 is connected to the feeder 802 through a movable sealing device. At the same time, the length of the feed shaft 804 is adjusted. The sealing ring 805 is placed in the discharge groove 806 through the length adjustment of the feed shaft 804, so that the raw material leaks out of the device, and the movable device of the cylinder 801 can drive the feed shaft 804 to move as a whole. A feed pipe 803 is provided inside the discharge groove 806 of the filler 8. The feed shaft 804 runs through the inside of the feed pipe 803. A sealing ring 805 is installed at the output end of the feed shaft 804. A discharge groove 806 used in conjunction with the sealing ring 805 is provided on the inner side of the filler 8. A cover plate 9 is installed at the bottom of the filler 8. The cover plate 9 protects and fixes the whole body, and also fixes the barrel body to prevent shaking and falling during transportation.

[0045] A protective shell 902 is provided inside the cover plate 9, a rubber pad 903 is movably installed inside the protective shell 902, and a pressure-sensitive sensor belt 901 is installed on one side wall of the rubber pad 903. The edge of the barrel body can be detected by the change of the pressure-sensitive sensor belt 901 to avoid deformation of the barrel body.

[0046] Workflow: S1. First, put the materials into the raw material bin 5, and then start the equipment. When the raw material bin 5 of the equipment feeds the materials into the feeder 1 at the bottom, the feeder 1 will inject the materials into the pressure booster 6. The output end of the pressure booster 6 inputs the materials into the filling machine 8 through a hose. At this time, place the raw material barrel into the clamp 10, and the clamp 10 will clamp it. Then, the edge detector 7 on one side of the turntable 404 will hold against the edge of the barrel. At this time, the electric motor 1101 in the cleaning assembly 11 starts to drive the one-way bearing 1107 to rotate. Since the one-way bearing 1107 is one-way, the outer shell of the one-way bearing 1107 will also rotate. Through the rotation of the outer shell by the worm and gear combination 1104, it drives the gear seat 1105 to rotate on the rotating shaft 1106 to complete the overall rotation. Then, the extended state of the electric telescopic rod 1108 changes to contraction, so that the vacuum cleaner 1103 is placed into the equipment. Then, start the vacuum cleaner 1103. When starting, the electric motor 1101 rotates in the reverse direction. At this time, the inside of the one-way bearing 1107 rotates and does not drive the overall rotation of the one-way bearing 1107. The vacuum cleaner 1103 will absorb impurities on the inner side of the barrel wall under the drive of the electric motor 1101. After the absorption is completed, the electric motor 1101 and the electric telescopic rod 1108 are started simultaneously to rotate the vacuum cleaner 1103 out from the other side. At this time, the mounting bracket 3 descends as a whole, so that the cover plate 9 covers the barrel. The turntable 404 drives the filling barrel to rotate as a whole. When the sliding resistor 703 and the pressure-sensitive sensing belt 901 show changes that do not conform to the set changes, it is determined that the barrel body is defective, and a warning is issued.

[0047] S2. If no signal abnormality is detected, normal filling will be carried out. At this time, the air cylinder 801 will start. When the air cylinder 801 extends, the sealing ring 805 will move to the discharge slot 806 position. At this time, the materials are discharged. When the discharge of the materials is completed, the air cylinder 801 shortens to contract the sealing ring 805, so as to seal the equipment. At the same time, the filling machine 8 stops.
