Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of paint production and processing equipment, and specifically to a dual-speed filling machine for paint. Background Technology
[0002] In the paint production and processing industry, especially in the color matching and filling process of latex paint, filling machines are one of the key pieces of equipment. Existing filling machines typically have functions such as automatic barrel dispensing, color matching, filling, capping, and labeling. These devices are set up on a conveyor belt, enabling a certain degree of automated production.
[0003] However, current filling machines have certain limitations in filling speed control. Specifically, while some machines can adjust the overall filling speed, their multiple filling heads typically use the same speed to fill the coating into the container, making it impossible to independently adjust the speed of different filling heads according to actual needs. This single-speed mode may lead to insufficient filling accuracy or low efficiency, especially in situations requiring a combination of rapid and precise filling, where existing equipment struggles to meet diverse production demands.
[0004] In response to the aforementioned existing technology, and to address the problem of insufficient filling accuracy or low efficiency caused by multiple filling heads typically using the same speed for filling, the applicant has designed a dual-speed filling machine for coatings. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a dual-speed filling machine for coatings.
[0006] This application provides a dual-speed filling machine for coatings, which adopts the following technical solution:
[0007] A dual-speed filling machine for paint includes a frame, a plurality of filling heads are provided on the top of the frame, a feed pipe is provided on the frame, one end of the feed pipe is provided with a branch pipe corresponding to each of the plurality of filling heads, the branch pipe is connected to the filling head, and the end of the feed pipe away from the filling head is connected to an external storage tank; each of the plurality of filling heads is provided with a control mechanism for controlling the discharge speed of the filling head.
[0008] By adopting the above technical solution, the coating in the external storage tank can be transported to each filling head through the inlet pipe and branch pipe. Each filling head has an independently installed control mechanism that can control the discharge speed of its corresponding filling head. During the filling process, the discharge speed of each filling head can be independently adjusted according to different filling requirements. For example, when rapid container filling is required, the filling head can be switched to high-speed filling mode; when the coating level in the container approaches the target capacity, the filling head can be switched to low-speed precision filling mode. This allows for flexible switching between rapid and precision filling, effectively improving filling efficiency and accuracy, and meeting diverse production needs.
[0009] Preferably, the control mechanism is a cylinder, which is located at the top of the filling head. The bottom of the filling head has a discharge port, and the piston rod of the cylinder is installed inside the filling head, facing the discharge port. The end of the piston rod of the cylinder is provided with a plug for sealing the discharge port.
[0010] By adopting the above technical solution, the cylinder, as the control mechanism, has advantages such as simple structure, rapid action response, and high control precision. When the piston rod of the cylinder retracts, it drives the plug to rise away from the discharge port. At this time, the discharge port is open, and the paint flows out rapidly under gravity or pump pressure, achieving high-flow-rate, high-speed filling. When the piston rod of the cylinder extends, the plug moves downward, reducing the flow cross-sectional area of the discharge port, thereby limiting the paint flow rate and switching to low-flow-rate, precise filling. When the piston rod of the cylinder is fully extended, the plug completely seals the discharge port, forcibly cutting off the paint flow and stopping filling. By controlling the different extension and retraction states of the cylinder piston rod, the relative position of the plug and the discharge port can be precisely controlled, thereby effectively adjusting the discharge speed of the filling head, meeting the filling requirements at different stages, and ensuring the stability and accuracy of the filling process.
[0011] Preferably, the feed pipe is equipped with a ball valve for coating flow and cut-off, and the frame is equipped with a ball valve switch for controlling the ball valve.
[0012] By adopting the above technical solution, the ball valve allows for convenient control of the flow and cut-off of coating material in the feed pipe. When filling operations need to be started, the operator opens the ball valve via the switch on the frame, allowing the coating material to smoothly flow through the feed pipe and branch pipe into the filling head, ensuring the normal start of the filling operation. When filling is completed or the equipment needs to be paused, closing the ball valve quickly cuts off the coating flow, preventing coating material from continuing to flow into the filling head and preventing overfilling or coating overflow. It also facilitates equipment maintenance and repair. In addition, the ball valve has excellent sealing performance, effectively preventing coating leakage, ensuring the safety and reliability of the production process, and preventing coating leakage from polluting the production environment.
[0013] Preferably, the frame is provided with a weighing platform for weighing the material in the feeding hopper, and the weighing platform is located at the bottom of the plurality of filling heads.
[0014] By adopting the above technical solution, the weighing platform can monitor the weight changes of the material in the container in real time, providing accurate weight data support for the filling process. During the filling process, the weighing platform can feed back the weight data of the container and the coating to the control system in real time. The control system uses this data to determine whether the coating level in the container is close to the target capacity, and then issues instructions in a timely manner to control the filling head to switch speeds or stop filling, achieving precise control of the filling volume. This ensures that the coating filling volume in each container reaches the preset target value, improving filling accuracy and reducing material waste.
[0015] Preferably, a support base is provided on the side of the frame away from the filling head, and a push cylinder is provided on the support base. A receiving tray is fixedly connected to the piston rod end of the push cylinder, and the receiving tray is located between the multiple filling heads and the weighing platform.
[0016] By adopting the above technical solution and setting up a receiving tray, a small amount of paint may still remain or drip after filling is completed and the filling head is closed. At this time, the cylinder drives the piston rod to move the receiving tray directly below the discharge port, which can catch these dripping paint. This can prevent paint from dripping onto the workbench, weighing platform, or outer wall of the container, keeping the production environment clean and reducing subsequent cleaning work. At the same time, it can also prevent paint dripping from corroding the equipment or affecting product quality, thereby improving the reliability and safety of production.
[0017] Preferably, a photoelectric sensor is provided on the frame, the photoelectric sensor is located above the weighing platform and is fixedly installed on the frame.
[0018] By adopting the above technical solution, the photoelectric sensor can detect whether a container is placed above the weighing platform and whether the container's position is correct. When there is no container or the container is misaligned, the photoelectric sensor will feed back a signal to the system, and the system will pause filling to prevent paint leakage, avoid material waste and pollution of the production environment. When a container is detected and its position is correct, the system will start the filling operation to ensure the accuracy and safety of the filling process. The installation of the photoelectric sensor improves the automation and intelligence level of the equipment, reduces manual intervention, lowers the labor intensity of operators, and also improves production efficiency and product quality stability.
[0019] Preferably, the frame is provided with a fixing plate for fixing multiple filling heads, and the fixing plate has fixing holes corresponding to the multiple filling heads one by one, and the multiple filling heads are inserted into the fixing holes.
[0020] By adopting the above technical solution, the fixing plate provides stable support for multiple filling heads, ensuring that the filling heads are accurately and firmly installed on the frame. The fixing holes on the fixing plate, each corresponding to a filling head, allow the filling heads to be precisely inserted into the holes, ensuring that the outlet of the filling head is aligned with the weighing platform and container below. This prevents splashing and leakage during paint filling due to misalignment of the filling head installation position, improving the accuracy and stability of the filling operation.
[0021] Preferably, the frame is also provided with a protective shell for sealing the multiple filling heads, one side of the protective shell is open, and the multiple filling heads are provided with the end of the opening near the discharge port.
[0022] By adopting the above technical solution, the protective shell can protect the filling head from external impacts, dust, debris, and other contaminants, thus extending its service life. The opening on one side of the protective shell allows the end of the filling head near the discharge port to extend for filling operations without affecting its normal use. Simultaneously, the protective shell also reduces the impact of paint evaporation on operators during the filling process, improving the safety and comfort of the production environment.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The paint in the external storage tank can be delivered to each filling head through the inlet pipe and branch pipe. Each filling head has an independently set control mechanism that can control the discharge speed of the corresponding filling head. During the filling process, the discharge speed of each filling head can be adjusted independently according to different filling needs. For example, when it is necessary to quickly fill the container, the filling head can be adjusted to the high-speed filling mode; when the paint level in the container is close to the target capacity, the filling head can be adjusted to the low-speed precision filling mode, thereby realizing flexible switching between fast filling and precision filling, effectively improving filling efficiency and accuracy, and meeting diverse production needs.
[0025] 2. The cylinder, as a control mechanism, has advantages such as simple structure, rapid action response, and high control precision. When the piston rod of the cylinder retracts, it drives the plug to rise away from the discharge port. At this time, the discharge port is open, and the paint flows out rapidly under gravity or pump pressure, achieving high-flow-rate, high-speed filling. When the piston rod of the cylinder extends, the plug moves down, reducing the flow cross-sectional area of the discharge port, thereby limiting the paint flow rate and switching to low-flow-rate, precise filling. When the piston rod of the cylinder is fully extended, the plug completely seals the discharge port, forcibly cutting off the paint flow and stopping filling. By controlling the different extension and retraction states of the cylinder piston rod, the relative position of the plug and the discharge port can be precisely controlled, thereby effectively adjusting the discharge speed of the filling head to meet the filling needs at different stages and ensure the stability and accuracy of the filling process.
[0026] 3. By setting up a receiving tray, after filling is completed and the filling head is closed, there may still be a small amount of paint residue or dripping. At this time, the cylinder drives the piston rod to move the receiving tray directly below the discharge port, which can catch these dripping paint. This can prevent paint from dripping onto the workbench, weighing platform or outer wall of the container, keep the production environment clean, reduce subsequent cleaning work, and at the same time prevent paint dripping from corroding the equipment or affecting product quality, thus improving the reliability and safety of production.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0032] This application discloses a dual-speed filling machine for paint.
[0033] Reference Figure 1 A dual-speed filling machine for paint includes a frame 1 and multiple filling heads 2. The multiple filling heads 2 are fixedly mounted on the frame 1, located on one side of the frame 1 near its top. A feed pipe 3 is provided on the frame 1, with a branch pipe 31 corresponding to each of the multiple filling heads 2 at one end, and the branch pipe 31 is connected to the filling head 2. The end of the feed pipe 3 away from the filling head 2 is connected to an external storage tank. Each of the multiple filling heads 2 is equipped with a control mechanism 4 for controlling the discharge speed of the filling head 2.
[0034] Reference Figure 2 and Figure 3 The control mechanism 4 is a cylinder 41, which is located at the top of the filling head 2. The piston rod of the cylinder 41 passes through the top of the filling head 2 and is located inside the filling head 2. Multiple filling heads 2 have discharge ports 21 at their bottoms. The piston rod of the cylinder 41 is positioned towards the discharge port 21. The end of the piston rod of the cylinder 41 is provided with a block 411 for sealing the discharge port 21.
[0035] During filling, the piston rod of cylinder 41 retracts, causing the plug 411 to rise away from the outlet 21, allowing the paint to flow out rapidly through the open outlet 21 under gravity or pump pressure. At this time, the filling head 2 is fully open, achieving high-flow-rate, high-speed filling, suitable for rapid filling of paint in containers. When the paint level in the container approaches the target capacity, the piston rod of cylinder 41 extends partially, and the plug 411 moves downward, reducing the flow cross-sectional area of the outlet 21. By adjusting the gap between the plug 411 and the outlet 21, the paint flow rate is limited, switching to low-flow, precise filling to avoid spillage and ensure filling accuracy. After reaching the set capacity, the piston rod of cylinder 41 extends fully, and the plug 411 completely seals the outlet 21, forcibly cutting off the paint flow and completing the filling process.
[0036] Specifically, a weighing platform 5 is installed on one side of the frame 1, located below the filling head 2 and fixedly mounted on the frame 1. A photoelectric sensor 6 is installed above the weighing platform 5 and fixedly mounted on the frame 1. The weighing platform 5 is used to place material buckets or other containers, and the photoelectric sensor 6 is used to detect whether there is a container on the weighing platform 5 below. If there is no container or the position is off, the system pauses filling to prevent paint leakage; if there is a container, the cylinder 41 is activated, causing the piston rod of the cylinder 41 to retract, driving the block 411 to rise, and the filling head 2 to start the high-speed filling mode, and the paint flows into the container quickly. When the weight data fed back by the weighing platform 5 shows that the paint level in the container is close to the target capacity, the control system issues another command, the piston rod of the cylinder 41 extends, the block 411 moves down, and the filling head 2 switches to the low-speed filling mode to accurately replenish the container. Once the weighing platform 5 detects that the weight has reached the preset filling amount, the control system immediately controls the piston rod of the cylinder 41 to extend fully, and the block 411 completely seals the discharge port 21, stopping the filling process.
[0037] A support base 7 is located on the side of the frame 1 opposite to the filling head 2. A push cylinder 8 is mounted on the support base 7, and a receiving tray 9 is fixedly installed at the end of the piston rod of the push cylinder 8. The receiving tray 9 is located below the discharge port 21 of the filling head 2. After filling is completed, a small amount of paint may still remain or drip when the filling head 2 is closed. The push cylinder 41 drives the piston rod to position the receiving tray 9 directly below the discharge port 21, which can catch these dripping paint, preventing contamination of the workbench, weighing platform 5, or container outer wall, and maintaining a clean production environment.
[0038] A fixing plate 10 is provided on the frame 1. The fixing plate 10 is located on the side of the frame 1 near the filling head 2, and multiple filling heads 2 are fixedly installed on the fixing plate 10. The fixing plate 10 has fixing holes that correspond one-to-one with the multiple filling heads 2, and the multiple filling heads 2 pass through and are fixed in the fixing holes.
[0039] The frame 1 is also provided with a protective shell 11 for sealing multiple filling heads 2. One side of the protective shell 11 is open, and the multiple filling heads 2 are located at one end of the discharge port 21 and extend out of the opening of the protective shell 11.
[0040] A ball valve 12 is installed on the feed pipe 3. The ball valve 12 is used to control the flow and cut off of paint in the feed pipe 3, and the switch of the ball valve 12 is located at the top of the frame 1. When the filling operation needs to be started, the ball valve 12 is opened, and the paint can smoothly pass through the feed pipe 3 and the branch pipe 31 into the filling head 2. When the filling is finished or the equipment needs to be stopped, the ball valve 12 is closed, which can quickly cut off the flow of paint and prevent paint from continuing to flow into the filling head 2, thus preventing overfilling or paint overflow.
[0041] The implementation principle of the application embodiment is as follows: the paint in the external storage tank flows into each filling head 2 through the feed pipe 3 and branch pipe 31 under the action of gravity or pump pressure. The piston rod of the cylinder 41 at the top of the filling head 2 drives the block 411 to extend and retract, realizing high-speed filling when the outlet 21 is open, low-speed fine filling when the gap is narrowed, and filling stopping when it is completely blocked. After the photoelectric sensor 6 detects that the container is in place, the weighing platform 5 provides real-time feedback of weight data. The control system links the cylinder 41 to switch the filling speed accordingly. After filling is completed, the push cylinder 8 drives the receiving tray 9 to receive the dripping paint. Moreover, multiple filling heads 2 can be independently adjusted to adapt to containers of different specifications. With the ball valve 12 to cut off the feed and the protective shell 11 for protection, a highly efficient, accurate and safe automated filling process is achieved.
[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
