Description

Technical Field

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

[0002] After the paint production is completed, it needs to be standardized and packaged through a high-precision filling process. At this time, professional paint quantitative packaging equipment becomes the core equipment. It uses an intelligent metering system to accurately control the capacity of a single can of paint, ensuring that each can of product reaches the preset weight standard, thereby ensuring product quality consistency and meeting the needs of industrialized mass production.

[0003] For example, the utility model patent CN221644583U discloses a paint quantitative dispensing device, in which "a motor drives a stirring roller to rotate, so as to stir the paint in the holding chamber and avoid the paint from separating. Then, the timer closing time of the flow controller is set according to the total amount of paint to be dispensed. Then, the flow controller controls the flow pipe to open, so that the paint in the holding chamber flows into the dispensing chamber through the flow pipe. After a set time, the flow controller controls the flow pipe to close. At this time, several sliding frames can be locked onto the inner wall of several dispensing pipes to prevent the paint from flowing only from the middle few dispensing pipes when the paint in the holding chamber first flows into the dispensing chamber, thus avoiding the separation of the paint." To address the uneven distribution of coatings during dispensing, a motor drives a screw to rotate, which in turn, under the action of a ball screw, causes a sliding frame to slide upwards. This allows several rubber stoppers to slide upwards, enabling the coating inside the dispensing chamber to flow downwards through several dispensing tubes into the dispensing bottles, thus achieving efficient and uniform quantitative dispensing of the coating. However, the drive motor is externally mounted on the top of the dispensing chamber to drive the screw inside. The upper end of the screw penetrates the dispensing chamber and connects to the output end of the drive motor. This structure has two major technical drawbacks: firstly, the through-type design compromises the sealing integrity of the dispensing chamber, making it prone to coating leakage from the transmission interface; secondly, external dust can enter the dispensing chamber through the transmission gap, posing a risk of product contamination. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a coating quantitative dispensing device, comprising a base plate, a lifting mechanism fixedly connected to one end of the base plate, an L-shaped plate fixedly connected to the lifting end of the lifting mechanism, a mixing tank installed at the upper end of the L-shaped plate, a discharge pipe of the mixing tank passing through the L-shaped plate and connected to a dispensing chamber via a solenoid valve, multiple dispensing tubes fixedly connected to the lower discharge port of the dispensing chamber, an electromagnet installed at the upper end of the dispensing chamber, an elastic component disposed inside the dispensing chamber, and multiple rubber plugs connected to the movable part of the elastic component, the rubber plugs being adapted to the dispensing tubes.

[0005] As an improvement to the above technical solution, the elastic component includes a guide rod, a sliding plate, a spring, and an iron block. Two guide rods are fixedly connected inside the dispensing cavity. A sliding plate is slidably disposed on the surface of the guide rod. The lower end of the sliding plate is fixedly connected to multiple rubber plugs. An iron block is fixedly connected to the upper end of the sliding plate. The iron block is aligned with an electromagnet. A spring is wound around the surface of the guide rod. The upper end of the spring is fixedly connected to the dispensing cavity, and the lower end of the spring is fixedly connected to the sliding plate.

[0006] As an improvement to the above technical solution, a buffer pad is fixedly provided on the inner wall of the dispensing cavity, and the buffer pad is aligned with the iron block.

[0007] As an improvement to the above technical solution, the lifting mechanism includes a slide rail, a motor, a lead screw, and a slider. The upper end of the slide rail is equipped with a motor, and a lead screw is rotatably installed inside the slide rail. The output end of the motor is fixedly connected to the lead screw, and a slider is slidably connected inside the slide rail. The lead screw passes through the slider and is threadedly connected to the slider.

[0008] As an improvement to the above technical solution, a receiving mechanism is installed on the surface of the L-shaped plate. The receiving mechanism includes a telescopic rod, a placement plate, a positioning hole, a receiving plate, and a limiting post. The telescopic rod is installed on the surface of the L-shaped plate, and a placement plate is installed at the telescopic end of the telescopic rod. A positioning hole is opened on the surface of the placement plate, and a limiting post is fixedly installed at the lower end of the receiving plate. The limiting post is adapted to the positioning hole.

[0009] The beneficial effects of this utility model are: The lifting mechanism can raise and lower the L-shaped plate and mixing tank, facilitating the injection of paint. It can also adjust the height of the dispensing chamber from the ground to adapt to the height requirements of different receiving buckets, ensuring smooth dispensing.

[0010] The electromagnet, elastic component, and rubber stopper work together to open the solenoid valve so that the paint flows into the dispensing chamber. Once a measured amount of paint has completely flowed into the dispensing chamber, the electromagnet is activated to release the rubber stopper from blocking the dispensing tube, allowing the paint to flow out evenly from multiple dispensing tubes and be accurately dispensed into the receiving container.

[0011] The electromagnet's magnetic force can control the moving part of the elastic component through the dispensing cavity to release the rubber stopper from blocking the dispensing tube. After dispensing is completed, the electromagnet is turned off, and the elastic component automatically resets, causing the rubber stopper to re-block the dispensing tube, ensuring the sealing and integrity of the dispensing cavity.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a coating quantitative dispensing device, including a base plate 1, a lifting mechanism 2 fixedly connected to one end of the base plate 1, an L-shaped plate 3 fixedly connected to the lifting end of the lifting mechanism 2, a mixing tank 4 installed at the upper end of the L-shaped plate 3, a discharge pipe of the mixing tank 4 passing through the L-shaped plate 3 and connected to a dispensing chamber 6 through a solenoid valve 5, a plurality of dispensing pipes 7 fixedly connected to the lower discharge port of the dispensing chamber 6, an electromagnet 8 installed at the upper end of the dispensing chamber 6, an elastic component 9 provided inside the dispensing chamber 6, a plurality of rubber plugs 10 connected to the movable part of the elastic component 9, and the rubber plugs 10 being adapted to the dispensing pipes 7.

[0016] In this implementation scheme, during actual operation, the user only needs to activate the lifting mechanism 2, which will cause the L-shaped plate 3 and the mixing tank 4 to rise and fall, bringing the mixing tank 4 to the ideal height so that the user can easily pour the paint into the mixing tank 4. After the paint is poured in, the user can use the lifting mechanism 2 again to adjust the height of the dispensing chamber 6 from the ground to adapt to the height requirements of different receiving buckets, ensuring a smooth and unobstructed dispensing process.

[0017] Subsequently, the mixing tank 4 begins to thoroughly mix the coating to ensure uniformity. Once mixing is complete, the user simply opens the solenoid valve 5, and a certain amount of coating will accurately flow into the dispensing chamber 6. After the appropriate amount of coating has completely entered the dispensing chamber 6, the user activates the electromagnet 8. The strong magnetic force generated by the electromagnet instantly attracts the movable part of the elastic component 9 upwards, causing the rubber stopper 10 to move upwards, thereby relieving the blockage in the dispensing tube 7.

[0018] At this point, the paint flows smoothly from multiple dispensing tubes 7 and precisely into multiple pre-placed receiving containers, achieving uniform dispensing of the paint. When the dispensing work is successfully completed, the user only needs to turn off the electromagnet 8, and the elastic component 9 will automatically reset under its own elastic force, causing the rubber stopper 10 to re-block the dispensing tubes 7, ensuring the sealing and integrity of the dispensing cavity 6.

[0019] Through the ingenious combination of electromagnet 8, elastic component 9 and rubber stopper 10, not only is uniform dispensing of coating achieved, but also the sealing and efficiency of the dispensing process are ensured. Since the magnetic force of electromagnet 8 can control the moving part of elastic component 9 through dispensing cavity 6, the sealing and integrity of dispensing cavity 6 can be guaranteed.

[0020] like Figure 3 As shown, the elastic component 9 includes a guide rod 91, a sliding plate 92, a spring 93, and an iron block 94. Two guide rods 91 are fixedly connected inside the dispensing cavity 6. The sliding plate 92 is slidably disposed on the surface of the guide rod 91. The lower end of the sliding plate 92 is fixedly connected to a plurality of rubber plugs 10. The upper end of the sliding plate 92 is fixedly connected to an iron block 94, which is aligned with the electromagnet 8. The surface of the guide rod 91 is wound with a spring 93. The upper end of the spring 93 is fixedly connected to the dispensing cavity 6, and the lower end of the spring 93 is fixedly connected to the sliding plate 92.

[0021] In this embodiment, the user activates the electromagnet 8, which generates a magnetic force that attracts the iron block 94 upwards. This causes the sliding plate 92 to slide upwards along the guide rod 91, thereby moving the rubber stopper 10 upwards and removing it from the dispensing tube 7. Simultaneously, the spring 93 is compressed. When the user turns off the electromagnet 8, the electromagnet 8 no longer attracts the iron block 94. Under the elastic force of the spring 93, the sliding plate 92, the iron block 94, and the rubber stopper 10 move downwards, causing the rubber stopper 10 to re-block the dispensing tube 7.

[0022] like Figure 3 As shown, a buffer pad 12 is fixedly installed on the inner wall of the dispensing cavity 6, and the buffer pad 12 is aligned with the iron block 94.

[0023] In this embodiment, when the electromagnet 8 attracts the iron block 94, the iron block 94 moves upward and impacts the buffer pad 12. The buffer pad 12 can buffer the impact of the iron block 94, thereby protecting the dispensing cavity 6 and the iron block 94.

[0024] like Figure 4As shown, the lifting mechanism 2 includes a slide rail 21, a motor 22, a lead screw 23, and a slider 24. The motor 22 is installed at the upper end of the slide rail 21. The lead screw 23 is rotatably installed inside the slide rail 21. The output end of the motor 22 is fixedly connected to the lead screw 23. The slider 24 is slidably connected inside the slide rail 21. The lead screw 23 passes through the slider 24 and is threadedly connected to the slider 24.

[0025] In this embodiment, the user starts the motor 22, which causes the output end of the motor 22 to rotate, thereby driving the lead screw 23 to rotate, which in turn drives the slider 24 to slide up and down inside the slide rail 21. As the slider 24 slides up and down, it can drive the L-shaped plate 3 to move up and down to adjust the height of the mixing tank 4 and the dispensing cavity 6.

[0026] like Figure 5 As shown, a receiving mechanism 11 is installed on the surface of the L-shaped plate 3. The receiving mechanism 11 includes a telescopic rod 111, a placement plate 112, a positioning hole 113, a receiving plate 114, and a limiting post 115. The telescopic rod 111 is installed on the surface of the L-shaped plate 3. The placement plate 112 is installed on the telescopic end of the telescopic rod 111. The positioning hole 113 is opened on the surface of the placement plate 112. The lower end of the receiving plate 114 is fixedly provided with a limiting post 115, which is adapted to the positioning hole 113.

[0027] In this embodiment, after the dispensing work is completed, the user activates the telescopic rod 111. The moving end of the telescopic rod 111 drives the placement plate 112 and the receiving tray 114 to move, so that the receiving tray 114 moves directly below the dispensing tube 7. Then the user can remove the receiving tube, so that the residual paint falls into the inside of the receiving tray 114, preventing the residual paint from dripping onto the surface of the base plate 1. At the same time, the cooperation between the positioning hole 113 and the limiting post 115 makes it easy for the user to disassemble and clean the receiving tray 114.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
