Description
Technical Field
[0001] The utility model relates to the technical field of high-viscosity glue filling, in particular to a glue filling device. Background Art
[0002] In the glue production and packaging industry, 2.5kg and 5kg filling barrels are often used for storage and transportation for easy transportation and use. When filling high-viscosity glue from top to bottom, a funnel is often used to prevent splashing, relying on the glue's own gravity. However, due to the strong intermolecular forces and high viscosity of high-viscosity glue, it flows slowly during filling. Furthermore, commonly used funnels on the market have a circular spout, which blocks the barrel opening when inserted into the filling barrel, preventing communication between the barrel and the atmosphere. As the glue is being filled, the pressure inside the barrel increases, making continuous glue filling impossible. To address this issue, two methods are commonly used: Option 1: inserting a spacer between the funnel and the barrel opening to facilitate air circulation. However, this spacer can easily shift during use, requiring manual adjustment to prevent spillage. Option 2: Before filling the glue, squeeze the barrel to reduce the pressure before inserting the funnel into the barrel opening to speed up the glue filling process. However, this method is cumbersome, and repeated squeezing of the barrel can cause deformation, making it impossible to ensure the barrel's complete sealing during subsequent transportation. Furthermore, it is unclear whether the deformed barrel will meet the filling requirements. Utility Model Content

[0015] The utility model is further described below.
[0016] The utility model provides a glue filling device, which is mainly used for filling high-viscosity barreled glue, and comprises a filling barrel 1 and a glue filling machine 2. The filling barrel 1 is placed below the glue outlet of the glue filling machine 2. The filling barrel 1 is provided with a cover body 3 adapted to the filling barrel 1. The center of the cover body 3 is provided with a glue filling component connected to the filling barrel 1. One end of the glue filling component is connected to the glue outlet of the glue filling machine 2, and the other end is connected to the filling barrel 1. The cover body 3 is also provided with a vent pipe 5 connected to the filling barrel 1, and the end of the vent pipe 5 away from the cover body 3 is connected to a vacuum pump 6.
[0017] like Figure 1As shown, the filling barrel 1 is placed under the glue filling machine 2, and the opening of the filling barrel 1 is aligned with the glue outlet of the glue filling machine 2. The filling barrel 1 is provided with a cover body 3 adapted to the opening of the filling barrel 1. The connection between the cover body 3 and the opening of the filling barrel 1 can be a cover, a clamp or a flange connection, etc. A glue filling component connected to the filling barrel 1 is provided in the center of the cover body 3. Specifically, a through hole for connecting the glue filling component to the glue filling barrel is opened in the center of the cover body 3; one end of the glue filling component is connected to the glue outlet of the glue filling machine 2, and the other end is connected to the filling barrel 1. The glue filling machine 2 fills glue into the filling barrel 1 through the glue filling component. The components can adopt existing glue filling tubes, glue filling guns and other devices; the cover body 3 is also provided with a vent pipe 5 connected to the filling barrel 1, and the vent pipe 5 is located on one side of the glue filling assembly. One end of the vent pipe 5 is connected to the inside of the filling barrel 1, and the other end is connected to a vacuum pump 6. The vacuum pump 6 and the vent pipe 5 are used to extract the gas in the filling barrel 1, reduce the air pressure in the filling barrel 1, and make the air pressure in the filling barrel 1 lower than the external air pressure, that is, a negative pressure is formed in the filling barrel 1, and the filling speed of high-viscosity glue is accelerated by the pressure difference; specifically, the cover body 3 is connected to the filling barrel 1 and the tightness and sealing of the connection between the cover body 3 and the filling barrel 1 are ensured to ensure the vacuum After the air pump 6 extracts the gas in the filling barrel 1, a negative pressure is formed in the filling barrel 1 to speed up the glue filling speed. After the cover body 3 is installed, the filling barrel 1 and the cover body 3 are placed together under the glue filling machine 2, and the glue inlet of the glue filling component set in the center of the cover body 3 is aligned with the glue outlet of the glue filling machine 2, so that glue flows from the glue filling machine 2 to the glue filling component, and glue is poured into the filling barrel 1 through the glue filling component. One end of the glue filling component is connected with the filling barrel 1, that is, one end of the glue filling component extends into the filling barrel 1. In order to prevent the glue from adhering to the cover body 3 after being output from the glue filling component during glue filling, the glue outlet of the glue filling component is longer than the height of the cover body 3. While pouring glue, turn on the vacuum pump 6 and use the vacuum pump 6 to extract the air in the filling barrel 1, so that the air pressure in the filling barrel 1 is lower than the external air pressure, so that a negative pressure is formed in the filling barrel 1. When only the filling component is connected to the filling barrel 1 and the outside world, the external air pressure will promote the glue to flow faster into the filling barrel 1, so as to achieve the purpose of quickly filling high-viscosity glue, reduce the time of glue filling, and improve the glue filling efficiency. The cover body 3 of the glue filling device can directly use the cover body that is matched with the filling barrel 1 when it is manufactured, without the need for additional customization, and the cover body 3 can be applied to the opening of the filling barrel 1 of the same model, and can be used repeatedly, saving production costs.
[0018] In order to facilitate transportation and storage, the canned barrels will adopt 2.5L and 5L models, which can withstand a smaller pressure in the barrel. In order to facilitate the control of the speed at which the glue flows out of the glue filling component and avoid the inability of the vacuum pump 6 to adapt to the glue filling speed of the glue filling component, resulting in excessive pressure in the barrel and failure to fill glue normally, the glue filling component includes a glue filling funnel 4, which is wide at the top and narrow at the bottom. The lower end of the glue filling funnel 4 passes through the cover 3 and extends into the filling barrel 1, and the upper end of the glue filling funnel 4 is aligned with the glue outlet of the glue filling machine 2; the glue filling funnel 4 is used as the glue filling component, and its wide at the top and narrow at the bottom shape enables the upper end of the glue filling funnel 4 to better receive the glue output from the glue outlet of the glue filling machine 2, and the lower end of the glue filling funnel 4 is aligned with the glue outlet of the glue filling machine 2. The narrow end not only makes it easy to set the glue pouring funnel 4 on the cover body 3, but also makes it easy to extend the lower end of the glue pouring funnel 4 into the glue pouring barrel for glue pouring, thereby avoiding glue splashing during glue pouring and playing a guiding role for high-viscosity glue; at the same time, the lower end of the glue pouring funnel 4 is narrower than the upper end, so that the side of the glue pouring funnel 4 is inclined, and a part of the high-viscosity glue is contained in the glue pouring funnel 4 for buffering when it is poured downward along the glue pouring funnel 4, that is, the glue pouring speed can be adjusted according to the speed of the air in the filling barrel 1 extracted by the vacuum pump 6, that is, the flow speed of the glue in the glue pouring funnel 4 can be adjusted according to the negative pressure in the filling barrel 1, effectively avoiding the problem of excessive pressure in the barrel and inability to quickly pour glue due to the inability to match the glue pouring speed and the air extraction speed.
[0019] In order to facilitate monitoring the filling degree of glue in the filling barrel 1 and avoid overflow due to excessive glue filling or insufficient glue filling that does not meet the filling requirements, a liquid level sensor 41 is provided on the outer side of the bottom end of the glue filling funnel 4, and the liquid level sensor 41 is electrically connected to a controller that controls the start and stop of the glue filling machine 2; specifically, a groove is provided on the outer side of the bottom end of the glue filling funnel 4, and the liquid level sensor 41 is arranged in the groove. By arranging the liquid level sensor 41 on the outer side of the bottom of the glue filling funnel 4, when the cover body 3 is installed on the filling barrel 1, the lower end of the glue filling funnel 4 extends into the filling barrel 1, and at this time the liquid level sensor 41 faces the bottom of the filling barrel 1. When the glue filling machine 2 fills glue into the glue filling funnel 4, high viscosity glue Water flows into the filling barrel 1 through the glue filling funnel 4. The liquid level sensor 41 monitors the height of the high-viscosity glue in the filling barrel 1 to determine whether it has reached the standard filling volume, and then feeds back the signal to the controller, which controls the start and stop of the glue filling machine 2. When the liquid level sensor 41 detects that the glue in the filling barrel 1 has reached the standard filling volume, it feeds back the signal to the controller, which controls the glue filling machine 2 to stop filling the glue. At this time, the glue filling is completed. However, it should be noted that when calculating the glue filling position, it is necessary to consider the amount of glue remaining in the glue filling funnel 4 after flowing into the filling barrel 1 when the glue filling machine 2 stops filling the glue, and appropriately lower the height of the standard filling volume of glue in the filling barrel 1.
[0020] In order to ensure the sealing between the glue filling component and the cover body 3 and avoid glue leakage during the glue filling process, which may cause waste or environmental pollution, a sealing ring 31 is provided on the inner side of the cover body 3. Specifically, a through hole corresponding to the glue filling component and the vent pipe 5 is opened on the sealing ring 31 to ensure the sealing between the cover body 3, the glue filling component, the vent pipe 5 and the filling barrel 1, and ensure that the vacuum pump 6 can extract the gas in the filling barrel 1 through the vent pipe 5 during the glue filling process, so that negative pressure is formed in the filling barrel 1, so that high-viscosity glue can quickly flow to the filling barrel 1 through the glue filling component, thereby improving the filling speed of high-viscosity glue, ensuring the filling quality while improving the filling efficiency and saving time and cost.
[0021] To facilitate the installation of the cover body 3 on the filling barrel 1, the filling barrel 1 is threadedly connected to the cover body 3; specifically, an external thread is provided at the opening of the filling barrel 1, and an internal thread adapted to the external thread is provided on the inner side of the cover body 3, so that the cover body 3 can be installed on the filling barrel 1 by screwing; the threaded connection between the filling barrel 1 and the cover body 3 is convenient for the installation of the cover body 3, and can ensure the connection stability between the cover body 3 and the filling barrel 1, ensuring that the cover body 3 will not loosen from the filling barrel 1 during the glue filling process; and it is easy to disassemble and install, reducing the assembly time between the cover body 3 and the filling barrel 1; and the cover body 3 can be simultaneously applied to all filling barrels 1 with adapted threads, can be used repeatedly, and has good versatility.
[0022] When one of the cover body 3 or the glue pouring component is damaged, the cover body 3 and the glue pouring component can be detachably connected for easy replacement; specifically, the cover body 3 and the glue pouring component can be connected in a plug-in manner, and a through hole for the glue pouring component to pass through is provided on the cover body 3, and the glue pouring component is connected to the filling barrel 1 through the through hole. At the same time, a limit plate with a diameter larger than the through hole is provided on the glue pouring component to limit the extension length of the glue pouring component to prevent the glue pouring component from extending too long into the filling barrel 1, resulting in the inability to be pulled out after glue pouring; the cover body 3 and the glue pouring component can also be connected in a threaded manner, specifically, a threaded section is provided on the glue pouring component, and an internal thread adapted to the threaded section is provided on the cover body 3, and the glue pouring component is connected to the cover body 3 by screwing.
[0023] In order to avoid glue leakage from the gap between the glue filling component and the cover body 3 during glue filling, the cover body 3 and the filling component are integrally formed; when a glue injection tube is used as a filling component, the glue injection tube and the cover body 3 can be directly made into one piece, and the lower end of the glue injection tube is longer than the length of the cover body 3, so that when the cover body 3 is subsequently connected to the filling barrel 1, the glue injection tube can be extended into the filling barrel 1 for glue filling, thereby preventing glue from sticking to the cover body 3; when a filling funnel is used as a filling column, the filling funnel and the cover body 3 are integrally made , and the narrow opening at the lower end of the filling funnel needs to be longer than the length of the cover body 3, so that when the cover body 3 is subsequently connected to the filling barrel 1, the lower end of the filling funnel can be extended into the filling barrel 1 for glue pouring, to avoid the glue sticking to the cover body 3 during glue pouring; at the same time, the glue pouring component and the cover body 3 made of one-piece molding can not only avoid glue leakage and ensure the sealing during the filling process, but also reduce the assembly time, and the entire device can be directly cleaned after disassembly, without worrying about damage caused by disassembly and reassembly.
