Description

Technical Field

[0001] The invention relates to the field of oil-proofing agent filling equipment, in particular to an anti-overflow filling device and a filling method for spraying an oil-proofing agent. Background Art

[0002] The spray oil-proofing agent is a fluorine-free alternative designed specifically for pulp molding. It does not contain harmful perfluorinated and polyfluorinated compounds (PFAs) and is intended to replace traditional fluorinated oil-proofing agents. The product is made of a film-forming comb-like polymer material and is carefully prepared using a special micro-emulsification technology. It has passed product testing for food contact containers to ensure its safety.

[0003] Spray oil-proof agent is particularly suitable for spraying process. The treated paper container can withstand the test of 700-watt microwave heating for 15 seconds and can remain stable at an instantaneous oil temperature of 100 degrees Celsius. Therefore, it is very suitable for making food packaging products such as microwave lunch boxes.

[0004] After processing, the spray oil-proof agent needs to be filled to facilitate subsequent sales. During filling, due to different product specifications, the filling containers are of different sizes.

During the entire raw material filling process, the storage box is in a closed state to prevent foreign matter from entering and prevent the raw materials from losing moisture. As the raw materials inside the storage box gradually decrease, the movable plate gradually moves downward, driving the movable rod to move downward until the trigger switch contacts the top of the top plate, causing the alarm to start and prompt personnel to add materials.

When the filling volume needs to be adjusted, connecting rods of different lengths are selected, and the upper and lower sides of the connecting rods are respectively fixed at the positions between the corresponding first perforations and the fixed rods through screws. At the same time, the baffles are replaced so that the spacing between the baffles is suitable for the required filling containers. When the first perforation position of the connection is closer to the center point of the turntable, the distance of the lifting piston block is smaller during rotation, so the filling volume is less, which is convenient for filling containers of different specifications and prevents the overflow of raw materials caused by excessive filling;

[0020] 2. The raw materials of the present invention are injected into the storage box through the feeding pipe. When negative pressure is formed inside the tank during filling, the raw materials are sucked into the tank through the injection pipe. At this time, the amount of raw materials inside the storage box is reduced. In this way, the movable plate is pressed downward under the action of atmospheric pressure to balance the pressure inside the storage box. In this way, during the whole raw material filling process, the storage box is in a closed state to prevent foreign matter from entering and prevent the raw materials from losing moisture;

[0021] 3. In the present invention, as the raw materials inside the storage box gradually decrease, the movable plate gradually moves downward, driving the movable rod to move downward until the trigger switch contacts the top of the top plate, so that the alarm is activated to prompt personnel to add materials. When adding materials, there are still raw materials inside the storage box, which is convenient for the continuous filling work and prevents the device from idling. Then, the feeding pipe is opened, and the movable plate is moved upward by the movable rod to reset the movable plate, and then the feeding pipe is used for feeding. After the feeding is completed, the feeding pipe can be closed by the sealing cover. BRIEF DESCRIPTION OF THE DRAWINGS

When the filling volume needs to be adjusted, the connecting rods 20 of different lengths are selected, and the upper and lower sides of the connecting rod 20 are respectively fixed at the corresponding positions between the first perforations 25 and the fixing rods 19 through the screws 35. At the same time, the baffles 6 are replaced so that the spacing between the baffles 6 is suitable for the required filling containers. When the first perforations 25 are closer to the center point of the turntable 24, the distance of the piston block 17 is smaller when it rotates, so the filling volume is less, which is convenient for filling containers of different specifications and prevents the overflow of raw materials caused by excessive filling.

[0040] When in use, the raw materials are injected into the storage box 7 through the feeding pipe 29. Then, when negative pressure is formed inside the tank body 9 during filling, the raw materials are sucked into the tank body 9 through the injection pipe 10. At this time, the amount of raw materials inside the storage box 7 is reduced, so the movable plate 27 is squeezed downward under the action of atmospheric pressure to balance the internal pressure of the storage box 7. In this way, during the entire raw material filling process, the storage box 7 is in a closed state to prevent foreign matter from entering and prevent the raw materials from losing moisture. As the raw materials inside the storage box 7 gradually decrease, the movable plate 27 gradually moves downward, driving the movable rod 28 to move downward until the trigger switch 33 contacts the top of the top plate 26, so that the alarm 8 starts to alarm, prompting personnel to add materials. When adding materials, there are still raw materials in the storage box 7, which is convenient for the continuous filling work and prevents the device from idling. Then, the feeding pipe 29 is opened, and the movable plate 27 is moved upward by the movable rod 28 to reset the movable plate 27, and then the feeding is carried out through the feeding pipe 29. After the feeding is completed, the feeding pipe 29 can be closed by the sealing cover 30.

9. The method for using the anti-overflow filling device for spraying oil-proofing agent according to claim 8, characterized in that: A method for using an anti-overflow filling device for spraying an oil-proofing agent, specifically comprising the following steps: When in use, an empty container is placed on the top of the marking ring (4), and then the second motor (15) is started. The second motor (15) drives the half gear (16) to rotate. When the half gear (16) is meshed with the gear (12), the half gear (16) drives the gear (12) to rotate, so that the conveyor belt (2) performs the transport work, until the marking ring (4) is located directly below the discharge pipe (14). At this time, the half gear (16) is separated from the gear (12), and the conveyor belt (2) stops transporting. At this time, filling is convenient. After the filling is completed, the filling mechanism starts the suction work, and then the half gear (16) continues to rotate until it is meshed with the gear (12), driving the gear (12) to rotate, so that the container after filling is transported away by the conveyor belt (2), and the subsequent empty container is transported to the lower end of the discharge pipe (14) again, and this process is repeated; When in use, the screw rod (35) is inserted into the first through hole (25), and the nut is sleeved on both sides of the screw rod (35) to limit the position of the screw rod (35). Then, the second through hole (21) at the top of the connecting rod (20) is sleeved on the outside of the screw rod (35), and the second through hole (21) at the bottom is sleeved on the outside of the fixed rod (19). Then, the nut is sleeved on the screw rod (35) to prevent the connecting rod (20) from being separated from the screw rod (35). Then, the first motor (22) is started, and the first motor (22) drives the rotating disk (24) to rotate. When the screw rod (35) moves upward under the action of rotation, the vertical rod (18) is pulled upward by the connecting rod (20), and the piston block (17) is driven to move upward. In this way, the raw material is sucked into the tank body (9) through the injection pipe (10). When the rotating disk (24) drives the screw rod (35) to reset When the filling volume is adjusted, the vertical rod (18) is pressed downward, driving the piston block (17) to move downward and reset, squeezing the raw materials inside the tank body (9), so that the raw materials are discharged through the second one-way valve (13) and the discharge pipe (14), completing the filling work. When the filling volume needs to be adjusted, connecting rods (20) of different lengths are selected, and the upper and lower sides of the connecting rod (20) are respectively fixed at the positions between the corresponding first perforations (25) and the fixing rod (19) through the screw rod (35). At the same time, the baffles (6) are replaced so that the spacing between the baffles (6) is suitable for the required filling container. When the position of the connected first perforation (25) is closer to the center point of the rotating disk (24), the distance of lifting the piston block (17) during rotation is smaller, so the filling volume is smaller, which is convenient for filling containers of different specifications and prevents the overflow of raw materials caused by excessive filling. When in use, the raw material is injected into the storage box (7) through the feeding pipe (29). Then, when a negative pressure is formed inside the tank body (9) during filling, the raw material is sucked into the tank body (9) through the injection pipe (10). At this time, the amount of raw material inside the storage box (7) decreases. Thus, the movable plate (27) is pressed downward under the action of atmospheric pressure to balance the pressure inside the storage box (7). Thus, during the entire raw material filling process, the storage box (7) is in a closed state to prevent foreign matter from entering and prevent the raw material from losing moisture. As the raw material inside the storage box (7) gradually decreases, the movable plate (27) is gradually opened. The movable rod (28) is gradually moved downward, driving the movable rod (28) to move downward until the trigger switch (33) contacts the top of the top plate (26), so that the alarm (8) is activated to remind the personnel to add materials. When adding materials, there are still raw materials inside the storage box (7), which is convenient for the continuous filling work and prevents the device from idling. Then, the feeding pipe (29) is opened, and the movable plate (27) is moved upward by the movable rod (28) to reset the movable plate (27), and then the feeding pipe (29) is used to feed materials. After the feeding is completed, the feeding pipe (29) is closed by the sealing cover (30).
