Description

Technical Field

[0001] This application relates to the field of liquid filling technology, specifically an automatic adhesive filling device. Background Technology

[0002] In modern industrial production, adhesives, as an important type of bonding material, are widely used in various fields. After production, adhesives typically need to be packaged into containers such as drums or bottles for sale and use. Currently, traditional adhesive filling largely relies on manual operation, using adhesive extraction machines to draw the adhesive and having workers visually measure it. This manual filling method has many drawbacks. On the one hand, manual operation is inefficient and cannot meet the needs of large-scale production; on the other hand, the accuracy of visual measurement is difficult to guarantee, easily leading to measurement errors. Furthermore, operational mistakes can cause problems such as adhesive spillage, resulting in adhesive waste and pollution of the production environment.

[0003] To address the problems associated with manual filling, related technologies have been continuously developed. For example, Chinese utility model patent CN222744065U discloses an automatic adhesive filling device. This device, through the coordination of a filling tube, guide frame, float plate, slide tube, and proximity switch, works as follows: during filling, the slide tube slides down, pushing the float plate into the packaging container. As adhesive is injected, the liquid level rises, causing the float plate to rise synchronously, which in turn pushes the slide tube upwards to contact the proximity switch, closing the solenoid valve and stopping the filling head. This design achieves quantitative filling of adhesives, effectively overcoming the shortcomings of manual filling such as low efficiency, inaccurate measurement, and easy glue overflow. However, in practical applications, this device utilizes the buoyancy of the glue to drive the float plate and slide tube upwards to trigger the proximity switch. Because the float plate is in direct contact with the glue, when the glue bucket or bottle is removed after filling, a large amount of glue adheres to the bottom of the float plate, causing glue to drip onto the ground. This not only pollutes the working environment but also wastes adhesive and increases production costs.

[0004] Therefore, this application provides an automatic adhesive filling device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides an automatic adhesive filling device, which aims to solve the problems mentioned in the background art, such as low efficiency, inaccurate measurement, easy overflow of adhesive leading to glue waste and environmental pollution, and some automatic filling devices causing glue to stick to parts due to structural defects, resulting in dripping pollution and increased costs.

[0006] To achieve the above objectives, this application provides the following technical solution: an automatic adhesive filling device, comprising a storage tank, a peristaltic pump fixedly installed on the storage tank and communicating with the storage tank, and a filling head connected to the output end of the peristaltic pump; further comprising a filling assembly for automatically starting and stopping filling; the filling assembly includes a support plate disposed on one side of the storage tank, a lifting plate movably disposed on the support plate, a positioning plate disposed above the lifting plate, a weighing sensor disposed between the lifting plate and the positioning plate, and a control module, wherein a solenoid valve is installed on the filling head. The support plate provides a stable foundation for the entire filling assembly; the positioning plate is used to place the buckets or bottles to be filled, serving a positioning function to ensure the accuracy of the filling position. Compared to traditional automatic filling devices that use float plates to trigger switches, which suffer from problems such as glue dripping and contaminating the ground due to float plate adhesion and glue waste, this automatic adhesive filling device uses a weighing sensor to monitor the filling weight in real time. It eliminates the need for triggering components that directly contact the adhesive, fundamentally avoiding pollution and waste caused by adhesive adhesion, maintaining a clean working environment, and reducing production costs. Furthermore, unlike traditional manual filling which relies on visual measurement, is inefficient, and prone to glue overflow, this device achieves stable adhesive delivery and precise on / off control through the cooperation of a peristaltic pump, filling head, and solenoid valve. The stable flow output of the peristaltic pump reduces adhesive waste, and the precise opening and closing of the solenoid valve under the control module greatly improves filling efficiency and measurement accuracy.

[0007] Preferably, the control module consists of a PLC controller, a human-machine interface (HMI), and Wi-Fi modules. The PLC controller is electrically connected to the solenoid valve, weighing sensor, and peristaltic pump. As the control core, the PLC controller can precisely control the solenoid valve, weighing sensor, and peristaltic pump, ensuring coordinated operation of all components and achieving an automated and precise filling process. The HMI provides operators with a convenient interactive window, allowing for intuitive parameter setting, operational status monitoring, and input of operating commands, reducing operational difficulty and improving operational convenience and accuracy.

[0008] Preferably, to facilitate the installation of the peristaltic pump and the filling head: a bracket is fixedly connected to the storage tank, and the peristaltic pump and the filling head are fixedly mounted on the bracket. The bracket fixedly mounted on the storage tank provides a stable mounting platform for the peristaltic pump and the filling head, ensuring that the peristaltic pump and the filling head remain stable during operation and preventing factors such as shaking from affecting the delivery and filling accuracy of the adhesive.

[0009] Preferably, to facilitate the hoisting of the storage tank, the top of the storage tank is provided with multiple lifting lugs, which are arranged in a ring around the central axis of the storage tank. These multiple lifting lugs, arranged in a ring around the central axis, provide reliable connection points for the hoisting operation. During equipment installation, handling, or maintenance, the storage tank can be easily and safely lifted and moved by connecting hoisting tools to the lifting lugs, reducing the labor intensity and safety risks of manual handling and improving work efficiency.

[0010] Preferably, the support plate consists of horizontal and vertical plates, with support legs fixedly connected to the four bottom corners of the horizontal plate, and the control module is mounted on the support plate. The horizontal and vertical plates of the support plate form a stable frame structure, providing reliable support for the entire filling assembly.

[0011] Preferably, to facilitate insertion of the filling head into the port of the barrel or bottle: the support plate is provided with a drive mechanism for driving the lifting plate to move up and down. The drive mechanism includes a T-shaped groove symmetrically opened at one end of the lifting plate near the vertical plate, a T-shaped guide rail slidably inserted into the T-shaped groove and fixedly connected to the vertical plate, and a lead screw mounted on the vertical plate through a bearing seat. The lifting plate is threaded onto the lead screw. A drive motor electrically connected to a PLC controller is fixedly installed at the top of the vertical plate, and the output end of the drive motor is fixedly connected to the top of the lead screw. The drive mechanism can accurately drive the lifting plate to move up and down, thereby causing the barrel or bottle on the positioning plate to move up and down, facilitating accurate insertion of the filling head into the port of the barrel or bottle, ensuring a smooth filling process, and avoiding adhesive overflow and waste caused by inaccurate alignment of the filling head with the barrel or bottle port.

[0012] Compared to traditional automatic filling devices that use float-triggered switches, which suffer from problems such as glue dripping and contaminating the ground due to float adhesion and glue waste, this application uses a weighing sensor to monitor the filling weight in real time. This eliminates the need for triggering components that directly contact the adhesive, fundamentally avoiding pollution and waste caused by adhesive-adhesive components, maintaining a clean working environment, and reducing production costs. Furthermore, unlike traditional manual filling which relies on visual measurement, is inefficient, and prone to glue overflow, this device achieves stable adhesive delivery and precise on / off control through the cooperation of a peristaltic pump, filling head, and solenoid valve. The stable flow output of the peristaltic pump reduces adhesive waste, and the precise opening and closing of the solenoid valve under the control module greatly improves filling efficiency and measurement accuracy.

[0013] The drive mechanism of this application can precisely drive the lifting plate to move up and down, thereby causing the barrel or bottle on the positioning plate to move up and down, which facilitates the accurate insertion of the filling head into the port of the barrel or bottle, ensuring the smooth progress of the filling process and avoiding adhesive overflow and waste caused by inaccurate alignment between the filling head and the port of the barrel or bottle.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Example 1

[0021] This embodiment provides an automatic adhesive filling device, such as... Figure 1-3As shown, the filling device includes a storage tank 1, a peristaltic pump 2 fixedly installed on the storage tank 1 and communicating with the storage tank 1, and a filling head 3 connected to the output end of the peristaltic pump 2; it also includes a filling assembly 4 for automatic start and stop filling; the filling assembly 4 includes a support plate 41 disposed on one side of the storage tank 1, a lifting plate 42 movably disposed on the support plate 41, a positioning plate 43 disposed above the lifting plate 42, a weighing sensor 44 disposed between the lifting plate 42 and the positioning plate 43, and a control module 45, and a solenoid valve 31 is installed on the filling head 3. The support plate 41 provides a stable support foundation for the entire filling assembly 4; the positioning plate 43 is used to place the buckets or bottles to be filled, playing a positioning role and ensuring the accuracy of the filling position; compared with the traditional automatic filling device that uses a float plate to trigger a switch, which has the problem of glue dripping and contaminating the ground due to the float plate sticking, and glue waste, this automatic adhesive filling device uses a weighing sensor 44 to monitor the filling weight in real time. There is no need for triggering components that directly contact the adhesive, which fundamentally avoids the pollution and waste caused by the sticking of components, keeps the working environment clean, and reduces production costs. At the same time, unlike the traditional manual filling that relies on visual measurement, is inefficient and prone to glue overflow, this device achieves stable delivery and precise on / off control of the adhesive through the cooperation of the peristaltic pump 2, the filling head 3, and the solenoid valve 31. The stable flow output of the peristaltic pump 2 reduces adhesive waste, and the solenoid valve 31 opens and closes precisely under the action of the control module 45, which greatly improves filling efficiency and measurement accuracy.

[0022] At the start of filling, the operator first places the bucket or bottle on the positioning plate 43. The load cell 44 quickly measures the initial weight of the bucket or bottle and transmits the data to the PLC controller in the control module 45. Then, the operator inputs the rated filling weight through the human-machine interface (HMI). The PLC controller analyzes and processes this input data and the initial weight data fed back by the load cell 44. After processing, the PLC controller sends a signal to open the solenoid valve 31 and simultaneously starts the peristaltic pump 2. The peristaltic pump 2 uses its own peristaltic squeezing principle to extract the adhesive from the storage tank 1 through the pipeline and deliver it to the filling head 3, which then injects it into the bucket or bottle. Throughout the filling process, the load cell 44 continuously monitors the weight of the adhesive in the bucket or bottle and feeds the data back to the PLC controller in real time. The PLC controller continuously compares the fed-back weight data with the set rated weight. When the weighing sensor 44 detects that the weight of the adhesive in the barrel or bottle has reached the rated value, the PLC controller immediately sends a signal to shut down the peristaltic pump 2 and the solenoid valve 31, stopping the filling process and achieving precise quantitative filling.

[0023] The control module 45 consists of a PLC controller, a human-machine interface (HMI), and Wi-Fi modules. The PLC controller is electrically connected to the solenoid valve 31, the load cell 44, and the peristaltic pump 2. As the core control unit, the PLC controller precisely controls the solenoid valve 31, the load cell 44, and the peristaltic pump 2, ensuring coordinated operation of all components and achieving an automated and precise filling process. The HMI provides operators with a convenient interactive window, allowing for intuitive parameter setting, operational status monitoring, and input of operating commands, reducing operational difficulty and improving convenience and accuracy. The addition of the Wi-Fi module enables the equipment to connect to the factory network, allowing management personnel to monitor equipment operation status and obtain production data in real time via a remote terminal, facilitating production scheduling and fault diagnosis, and improving the efficiency and intelligence of production management. The PLC controller receives weight data signals from the load cell 44 through a pre-written program and sends control signals to the solenoid valve 31 and the peristaltic pump 2 according to the set logic rules. The Human-Machine Interface (HMI) connects to the PLC controller via a communication interface. Operators input parameters such as the rated filling weight and operating mode into the HMI, which converts these parameters into electrical signals and transmits them to the PLC controller. Simultaneously, the HMI displays real-time equipment operating status and weighing data for easy monitoring. A Wi-Fi module wirelessly transmits equipment operating and production data collected by the PLC controller. Management personnel can access the equipment network via authorized devices such as mobile phones and computers to obtain data and perform remote operation and management. The PLC controller is a Siemens S7-1200.

[0024] To facilitate the installation of the peristaltic pump 2 and the filling head 3, a bracket 11 is fixedly connected to the storage tank 1, and the peristaltic pump 2 and the filling head 3 are fixedly mounted on the bracket 11. The bracket 11, fixedly mounted on the storage tank 1, provides a stable mounting platform for the peristaltic pump 2 and the filling head 3, ensuring their stability during operation and preventing factors such as shaking from affecting the delivery and filling accuracy of the adhesive. Simultaneously, this integrated installation design makes the equipment structure more compact, saves installation space, facilitates equipment layout and maintenance, and improves the overall stability and reliability of the equipment. The bracket 11 is firmly fixed to the storage tank 1 by welding, bolting, or other methods, providing support points for the peristaltic pump 2 and the filling head 3. The peristaltic pump 2 and the filling head 3 are fixedly mounted on the corresponding positions of the bracket 11 by bolts, clips, or other methods, ensuring that they will not shift or shake during operation. During the adhesive delivery and filling process, the support 11 bears the weight of the peristaltic pump 2 and the filling head 3, as well as the vibration and pressure generated during operation, and transmits these forces to the storage tank 1 to ensure stable operation of the equipment.

[0025] To facilitate the hoisting of storage tank 1, multiple lifting lugs 12 are provided on the top of storage tank 1, arranged in a ring around the central axis of storage tank 1. These lugs provide reliable connection points for hoisting operations. During equipment installation, handling, or maintenance, the storage tank 1 can be easily and safely lifted and moved by connecting hoisting tools to the lugs 12, reducing the labor intensity and safety risks of manual handling and improving work efficiency. The lugs 12 are securely fixed to the top of storage tank 1 by welding or other methods and are evenly distributed. During hoisting, hoisting ropes or chains pass through the lugs 12 to form a connection, and the hoisting force of hoisting equipment (such as cranes, forklifts, etc.) is used to lift the storage tank 1.

[0026] The support plate 41 consists of a horizontal plate and a vertical plate. Support legs are fixedly connected to the four corners of the bottom of the horizontal plate. The control module 45 is mounted on the support plate 41. The horizontal and vertical plates of the support plate 41 form a stable frame structure, providing reliable support for the entire filling assembly 4. The horizontal and vertical plates are fixed together by welding, bolting, or other methods to form the support plate 41, providing a mounting base for components such as the lifting plate 42, positioning plate 43, and weighing sensor 44. The support legs are fixed to the four corners of the bottom of the horizontal plate by bolts, with their bottoms in contact with the ground, transferring the weight of the support plate 41 and the equipment mounted on it to the ground. During equipment installation, the height of the support legs can be adjusted to keep the support plate 41 level, ensuring the accuracy of the measurement data from the weighing sensor 44. The control module 45 is installed in a suitable position on the support plate 41, allowing operators to easily operate and maintain it.

[0027] Example 2

[0028] Unlike Embodiment 1, in order to facilitate the insertion of the filling head 3 into the port of the barrel or bottle: the support plate 41 is provided with a drive mechanism 5 for driving the lifting plate 42 to move up and down. The drive mechanism 5 includes a T-shaped groove 421 symmetrically opened at one end of the lifting plate 42 near the vertical plate, a T-shaped guide rail 51 slidably inserted into the T-shaped groove 421 and fixedly connected to the vertical plate, and a lead screw 52 mounted on the vertical plate through a bearing seat. The lifting plate 42 is threaded onto the lead screw 52. A drive motor 53 electrically connected to the PLC controller is fixedly installed at the top of the vertical plate. The output end of the drive motor 53 is fixedly connected to the top of the lead screw 52. The drive mechanism 5 precisely drives the lifting plate 42 to move up and down, thereby causing the buckets or bottles on the positioning plate 43 to move up and down. This facilitates the accurate insertion of the filling head 3 into the port of the bucket or bottle, ensuring a smooth filling process and preventing adhesive spillage and waste due to inaccurate alignment between the filling head 3 and the bucket or bottle port. The cooperation between the T-slot 421 and the T-rail 51 provides good guidance and support for the movement of the lifting plate 42, ensuring the stability and accuracy of the lifting plate 42's movement and reducing swaying and offset. The threaded transmission between the lead screw 52 and the lifting plate 42 provides high transmission accuracy and enables precise displacement control of the lifting plate 42, meeting the filling needs of buckets or bottles of different specifications. The drive motor 53, as a power source, features stable speed and convenient control, and can be automated through the control module 45, improving the intelligence and automation level of the equipment. The drive motor 53 is fixedly installed at the top of the vertical plate, and its output shaft is fixedly connected to the top of the lead screw 52 through a coupling and other components. When the drive motor 53 is powered on, it drives the lead screw 52 to rotate. The lifting plate 42 is fitted onto the lead screw 52 through an internal threaded hole. According to the principle of threaded transmission, the rotation of the lead screw 52 is converted into the vertical linear motion of the lifting plate 42. A T-shaped guide rail 51 is fixedly installed on the vertical plate, and a T-shaped groove 421 is formed at the end of the lifting plate 42 near the vertical plate. The T-shaped groove 421 and the T-shaped guide rail 51 slide and engage. During the movement of the lifting plate 42, the T-shaped guide rail 51 provides guidance and support, restricting its horizontal movement and ensuring that the lifting plate 42 can only slide up and down along the T-shaped guide rail 51, thereby achieving precise alignment between the filling head 3 and the barrel or bottle port. The PLC controller in the control module 45 controls the start / stop and speed of the drive motor 53 according to the filling requirements, achieving precise control of the lifting motion of the lifting plate 42.

[0029] The wiring diagram of the peristaltic pump 2 and the drive motor 53 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the peristaltic pump 2 and the drive motor 53 will not be explained in detail.

[0030] The control method of this application is through a control module. The control circuit of the control module can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0031] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto.
