Description

Technical Field

[0001] This utility model relates to the field of quantitative filling equipment technology, and in particular to a quantitative filling equipment for adhesive production. Background Technology

[0002] Adhesives are adhesive substances with excellent bonding properties, capable of tightly bonding two or more materials of the same or different types together. Adhesives are usually in a viscous liquid state and are injected through injection tubes. During injection, a weighing device is installed below to monitor the weight. Once a certain weight is reached, the injection of adhesive is stopped, achieving the effect of quantitative filling and injection.

[0003] Currently, when filling adhesives, workers place the bottles directly on the work platform. However, this method not only wastes a lot of time aligning the bottle necks, but also makes the bottles prone to tipping over due to external factors. Furthermore, existing filling machines lack filtration capabilities during adhesive delivery, which easily leads to clogging of the filling head. Additionally, the adhesive, due to its viscosity, easily adheres to the inner wall of the filling head during injection, causing not only clogging but also adhesive waste. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a quantitative filling device for adhesive production to more accurately resolve these issues.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a quantitative filling device for adhesive production, including a base plate, a frame mounted on the base plate, and a filling assembly mounted on the frame. The filling assembly includes a lifting component connected to the frame and a control valve connected to the output end of the lifting component. The input end of the control valve is connected to an external storage tank via a pipe, and the output end of the control valve is connected to a filling head. A limiting component for restricting the bottle is provided on the base plate. The limiting component includes a motor mounted on one side of the base plate, a bidirectional lead screw connected to the output end of the motor and mounted inside the base plate, and two sleeves connected to the bidirectional lead screw. The tops of the two sleeves pass through the base plate and are connected to a limiting plate. A groove for installing the lead screw is provided inside the base plate. Two sliding grooves that cooperate with the sleeves are provided on the top of the base plate. A weighing component is provided at the center of the top of the base plate, between the two sliding grooves.

[0007] Furthermore, a filter element is provided between the pipeline and the output end of the control valve and the storage tank. The filter element includes a first annular body and a second annular body threadedly connected to the first annular body. A first filter screen is provided inside the first annular body, and a second filter screen is provided inside the second annular body. First threaded rings are provided on both sides of the first annular body, and second threaded rings that cooperate with the first threaded rings are provided on both sides of the second annular body. A sealing ring is provided inside the second threaded ring. Several evenly distributed barrier grooves are provided inside the lower part of the first annular body and the second annular body.

[0008] Furthermore, the front end of the frame is provided with an auxiliary slide rail, an L-plate is slidably connected inside the auxiliary slide rail, an auxiliary slider that cooperates with the auxiliary slide rail is provided on the inner side of the L-plate, the outer side of the L-plate is connected to a control valve, and the middle of one side of the L-plate is connected to the output end of the lifting component.

[0009] Furthermore, the lifting component of this invention includes a cylinder.

[0010] Furthermore, the present invention provides a mounting bracket for mounting an ultrasonic oscillator on one side of the base plate. An amplitude transformer is connected to the output end of the ultrasonic oscillator, and a tool head is connected to the amplitude transformer. The tool head contacts one side of the filling head, and an adjustment groove that cooperates with the tool head is provided on one side of the filling head.

[0011] The beneficial effects of this utility model are:

[0012] The lifting mechanism allows the filling head to move up or down, ensuring contact and disengagement between the filling head and the bottle, thus enabling the filling head to complete the filling of the adhesive and the switching of the bottle. The limiting component restricts the position and movement of the bottle, ensuring that the relative position of the filling head and the bottle remains consistent and preventing inaccurate filling due to bottle shaking or displacement. Furthermore, the bottle's limiting function keeps the bottle stable during the filling process, reducing liquid splashing caused by bottle shaking.

[0013] The first and second filters are designed to block impurity particles in the adhesive. One of the filters is a coarse filter, and the other is a fine filter. This design allows for dual filtration of impurities, effectively reducing the impurity content in the adhesive. The barrier grooves store the impurity particles blocked by the filters, effectively preventing them from clogging the filters.

[0014] The ultrasonic oscillator, amplitude transformer, and tool head provide vibration to the filling head. This vibration acts on the adhesive inside the filling head, preventing it from sticking to the inner wall of the filling head during injection. Simultaneously, the vibration is transmitted to the filter elements, causing impurities adhering to the first and second filter screens to fall into the barrier groove. This prevents the first and second filter screens from clogging and increases the service life of the first and second filter screens and the filling head. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] refer to Figure 1-6 A quantitative filling device for adhesive production includes a base plate 1, a frame 11 mounted on the base plate 1, and a filling assembly 2 mounted on the frame 11. The filling assembly 2 includes a lifting component 21 connected to the frame 11 and a control valve 22 connected to the output end of the lifting component 21. The input end of the control valve 22 is connected to an external storage tank via a pipe 23, and the output end of the control valve 22 is connected to a filling head 24. A limiting component 3 for restricting the bottle is provided on the base plate 1. The limiting component 3 includes... A motor 31 is disposed on one side of the base plate 1, a bidirectional lead screw 32 connected to the output end of the motor 31 and disposed in the base plate 1, and two sleeves 33 connected to the bidirectional lead screw 32. The tops of the two sleeves 33 pass through the base plate 1 and are connected to a limiting plate 34. The interior of the base plate 1 is provided with a groove 35 for installing the lead screw. The top of the base plate 1 is provided with two sliding grooves 36 that cooperate with the sleeves 33. A weighing member 12 is disposed at the top center of the base plate 1 and between the two sliding grooves 36.

[0025] The lifting component 21 enables the filling head 24 to move up or down, ensuring that the filling head 24 contacts and detaches from the bottle, thus allowing the filling head 24 to complete the filling of the adhesive and the switching of the bottle. The limiting component 3 restricts the position and movement of the bottle, ensuring that the relative position of the filling head 24 and the bottle remains consistent and avoiding inaccurate filling due to bottle shaking or displacement. Moreover, the limiting of the bottle keeps the bottle stable during the filling process, reducing liquid splashing caused by bottle shaking.

[0026] Specifically, the motor 31 can drive the bidirectional lead screw 32 to rotate, and the two sleeves 33 will move inward or outward synchronously due to the rotation of the bidirectional lead screw 32, thereby adjusting the distance between the two limiting plates 34, so that the two limiting plates 34 can fix bottles of different sizes.

[0027] In this embodiment, the limiting plate 34 is L-shaped, and an elastomer, including rubber, is provided on the contact surface between the limiting plate 34 and the bottle.

[0028] In this embodiment, the weighing device 12 and the control valve 22 work together to enable the filling head 24 to perform quantitative filling of the adhesive. The control valve 22 and the weighing device 12 work together by first performing rapid coarse filling through volumetric metering to reach 90% to 95% of the target amount, and then using a weighing sensor to provide real-time feedback on the weight for precise replenishment.

[0029] In this embodiment, the technology of feeding raw materials from the storage tank into the pipeline 23 is existing. A liquid pump can be used, or existing technologies can be employed, such as connecting the top of the storage tank to a compressed air source. When the system starts, compressed air enters the top of the storage tank, increasing the pressure inside. Simultaneously, the liquid inside the storage tank flows through the pipeline 23 to the filling head 24 under pressure. During the filling process, a pressure control system maintains stable pressure inside the storage tank, ensuring that the liquid flows to the filling head 24 at a stable flow rate.

[0030] In this embodiment, the control valve 22 includes a solenoid valve or a pneumatic valve, wherein either the solenoid valve or the pneumatic valve can be an existing type.

[0031] like Figure 3 and Figure 4 As shown, a filter element 4 is provided between the pipe 23 and the output end of the control valve 22 and the storage tank. The filter element 4 includes a first annular body 41 and a second annular body 42 threadedly connected to the first annular body 41. A first filter screen 411 is provided inside the first annular body 41, and a second filter screen 421 is provided inside the second annular body 42. A first threaded ring 412 is provided on both sides of the first annular body, and a second threaded ring 422 that cooperates with the first threaded ring 412 is provided on both sides of the second annular body 42. A sealing ring is provided inside the second threaded ring. Several evenly distributed barrier grooves 43 are provided at the lower part of the interior of the first annular body 41 and the second annular body 42.

[0032] The filter element 4 can block impurity particles in the adhesive, which can protect the filling head 24 and prevent the filling head 24 from clogging.

[0033] Specifically, the first filter screen 411 and the second filter screen 421 are designed to block impurity particles in the adhesive. The first filter screen 411 is a coarse filter screen and the second filter screen 421 is a fine filter screen. This design allows for dual filtration of impurities, effectively reducing the impurity content in the adhesive. The barrier groove 43 is designed to store the impurity particles blocked by the filter screen, effectively preventing the impurity particles from clogging the filter screen.

[0034] The advantage of using a threaded connection between the first annular body 41 and the second annular body 42 is that it facilitates the installation and disassembly of the first annular body 41 and the second annular body 42 by the workers. The connection between the first annular body 41 and the second annular body 42 and the pipe 23 and the air control device is also a screw connection.

[0035] In this embodiment, the coarse filter can be a filter with a pore size of 50 μm, while the fine filter can be a filter with a pore size of 5 μm.

[0036] like Figure 2 As shown, an auxiliary slide rail 26 is provided at the front end of the frame 11, and an L-plate 27 is slidably connected inside the auxiliary slide rail 26. An auxiliary slider 271 that cooperates with the auxiliary slide rail 26 is provided on the inner side of the L-plate 27. The outer side of the L-plate 27 is connected to the control valve 22, and the middle part of one side of the L-plate 27 is connected to the output end of the lifting component 21.

[0037] The auxiliary slide rail 26 and the auxiliary slider 271 can limit the range of motion of the control valve 22, so that the control valve 22 can only move up and down along the preset track, and ensure the accuracy of the movement of the control valve 22.

[0038] In this embodiment, the lifting component 21 includes a cylinder.

[0039] like Figure 6 As shown, a mounting bracket 5 for mounting an ultrasonic oscillator 6 is provided on one side of the base plate 1. An amplitude transformer 61 is connected to the output end of the ultrasonic oscillator 6. A tool head 62 is connected to the amplitude transformer 61. The tool head 62 is in contact with one side of the filling head 24. An adjustment groove 25 that cooperates with the tool head 62 is provided on one side of the filling head 24.

[0040] The ultrasonic oscillator 6, amplitude transformer 61, and tool head 62 provide vibration to the filling head 24. This vibration acts on the adhesive inside the filling head 24, preventing the adhesive from sticking to the inner wall of the filling head 24 during the injection process. Simultaneously, the vibration is transmitted to the filter element 4, causing impurities attached to the first filter screen 411 and the second filter screen 421 to fall into the barrier groove 43. This prevents the first filter screen 411 and the second filter screen 421 from becoming clogged and increases the service life of the first filter screen 411, the second filter screen 421, and the filling head 24.

[0041] Working principle:

[0042] First, the bottle is removed and placed on the weighing device 12. The motor 31 is then started, driving the double-acting screw 32 to rotate. The two sleeves 33 move inward synchronously due to the rotating screw 32, providing a pushing force to the bottle and fixing it in the center of the weighing device 12, opposite the filling head 24. Next, the cylinder output provides a downward pushing force, causing the auxiliary slider 271 to move downward along the auxiliary slide rail. This causes the control valve 22 to move downward synchronously, completing the connection between the filling head 24 and the bottle. Then, the adhesive in the storage tank passes sequentially through the filter element 4, pipe 23, and control valve 24. Valve 22, and finally the adhesive is injected into the bottle through filling head 24, completing the filling process. During the filling process of the adhesive by filling head 24, the ultrasonic oscillator 6, amplitude rod 61 and tool head 62 can provide vibration force to filling head 24. The vibration force will act on the adhesive inside filling head 24, which can make the adhesive adhere to the inner wall of filling head 24. At the same time, the vibration will be transmitted to the filter element 4, and the impurities attached to the first filter screen 411 and the second filter screen 421 will fall into the barrier groove 43, thereby avoiding the clogging of the first filter screen 411 and the second filter screen 421, and increasing the service life of the first filter screen 411, the second filter screen 421 and the filling head 24.

[0043] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.

[0044] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
