Description

Technical Field

[0001] The utility model belongs to the technical field of coating production, and in particular relates to a formaldehyde-removing and antibacterial coating filling device. Background Art

[0002] Water-based paint, also known as coating, is a slurry-like spray material using water as a diluent. With increasing user demand and product development, a number of functional coatings have emerged. For example, formaldehyde-removing and antimicrobial coatings are one such type of functional coating that possesses both formaldehyde removal and antimicrobial properties. Traditionally, finished paints are sold in barrels. Traditionally, barrel filling involves manual filling and weighing, which is labor-intensive and inefficient. With the advancement of industrial mechanization, where machines replace humans, filling machines have become crucial equipment in paint packaging lines. However, existing paint filling machines still face numerous challenges. These include a low degree of automation, requiring frequent manual intervention, and requiring further efficiency improvement. Metering is inaccurate, resulting in large errors in the amount of paint filled per barrel. Furthermore, filling machines lack compatibility and are difficult to adjust, making them unable to accommodate barrels of varying heights and sizes. Consequently, the volume of finished barreled products is relatively limited, making it difficult to meet the diverse packaging needs of large and small barrels. Therefore, upgrading existing paint filling machines is urgently needed. Utility Model Content

[0003] In view of the above situation, the utility model provides a formaldehyde-removing and antibacterial coating filling device with a higher degree of automation, wider adaptability and more accurate filling and metering.

[0004] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A formaldehyde-removing antibacterial paint filling device comprises a conveyor for conveying packaging barrels and a filling machine for pouring the paint.

[0006] The conveyor is a roller conveyor, which includes a frame and a plurality of rollers rotatably arranged on the upper part of the frame. The rollers are connected by chain transmission. A conveying motor for driving the rollers to rotate is provided on one side of the frame.

[0007] The filling machine includes a storage tank for holding the paint to be filled, the storage tank is located on one side of the conveyor, a filling platform is provided on the top of the storage tank, a filling box is provided above the filling platform which can be raised and lowered by a screw elevator, and a lifting motor for driving the screw to rise and fall is provided on one side of the screw elevator.

[0008] There are multiple fillers in the filling box, and the conveyor is located directly below each filler. The conveyor is provided with multiple filling stations corresponding to the number of fillers, and the frame of the conveyor at each filling station is provided with an induction electric eye for detecting the packaging barrel.

[0009] The injector includes a vertical cylindrical syringe and a sliding piston that can be pushed and pulled inside the syringe. A suction port is provided on the lower side wall of the syringe, and a discharge port is provided at the bottom of the syringe. The suction port extends to the bottom of the storage tank through a suction pipe, and the discharge port is placed directly above the packaging barrel. The suction port and the discharge port are respectively provided with a one-way valve structure, and a servo electric cylinder for pushing and pulling the sliding piston is connected above the sliding piston.

[0010] An electric control box is provided on one side of the filling station, and the induction electric eyes, conveying motors, lifting motors, and servo electric cylinders are all electrically connected to the electric control box.

[0011] Preferably, the filling box is a rectangular hollow box, the screw elevator is located in the middle position below the filling box, and four retractable guide columns are arranged around the screw elevator to ensure the lifting and sliding guidance and auxiliary support balance of the filling box.

[0012] Preferably, a horizontally retractable material receiving box is provided below the filling box near the discharge port of each injector. The bottom of the material receiving box is connected to the material storage tank through a recovery pipe. A horizontally arranged telescopic cylinder is connected to each end of the material receiving box, and the telescopic cylinder is connected to the bottom of the filling box through a connecting seat. Since the formaldehyde-removing antibacterial paint is a slurry material with a certain viscosity, residual paint will inevitably drip from the discharge port of the injector after the paint is poured. Therefore, after one batch of paint is poured, before the conveyor continues to convey the next batch of packaging barrels to the place, it is necessary to control the material receiving box to extend to the bottom of the injector discharge port to catch the dripping residual paint. Before starting the next batch of paint pouring, the material receiving box is controlled to retract and completely release the injector discharge port so as not to interfere with the injector pouring again. On the one hand, it can prevent the residual paint from continuing to drip into the packaging barrel and affecting the paint filling and metering accuracy. On the other hand, it can also prevent the residual paint from dripping onto the outer wall of the packaging barrel or the conveyor roller, causing barrel wall pollution or roller dirtiness.

[0013] Preferably, a feed port is provided on one side of the top of the storage tank for replenishing paint into the storage tank, and a breathing port is provided on the other side of the top of the storage tank for breathing in and out of the storage tank.

[0014] Preferably, a plurality of supporting legs are provided below the frame of the conveyor, and an adjustable anchor screw is provided at the bottom of each supporting leg.

[0015] The present invention also includes other components that enable it to be used normally, which are all conventional means in the field. In addition, devices or components not limited in the present invention, such as: roller conveyors, screw elevators, retractable guide columns, induction electric eyes, servo electric cylinders, electric control boxes and their internal control circuit settings, etc., all adopt existing technologies in the field.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model provides a formaldehyde-removing and antibacterial paint filling equipment with a high degree of automation, which reduces manual labor and helps to improve paint filling efficiency; the equipment has strong adaptability and is easy to adjust, and can better adapt to packaging barrels of different sizes, which is conducive to expanding product packaging specifications and categories; the filling measurement is more accurate, ensuring the quality of barreled paint products.

[0020] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0021] Example

[0022] like Figure 1-2 As shown, a formaldehyde-removing antibacterial paint filling device includes a conveyor for conveying packaging barrels 27 and a filling machine for paint filling, and the filling machine is located on one side of the conveyor.

[0023] The conveyor is a roller conveyor, which includes a frame 1 and several rollers 2 rotatably arranged on the upper part of the frame. The rollers are connected by chains (not shown in the figure). A conveying motor 3 for driving the rollers to rotate is provided on one side of the frame.

[0024] The conveyor frame is equipped with multiple legs 4, and each leg is equipped with an adjustable anchor screw 5 at the bottom. If necessary, the overall height of the roller conveyor frame can be slightly adjusted to accommodate the height of the packaging barrel. The roller conveyor adopts existing technology, and the specific configuration will not be described in detail here.

[0025] The filling machine includes a storage tank 6 for holding the paint to be filled, a feed port 7 is provided on one side of the top of the storage tank for replenishing the paint into the storage tank, and a breathing port 8 is provided on the other side of the top of the storage tank for breathing in and out of the storage tank, which can maintain the air pressure balance in the storage tank and ensure the replenishment of the material and the suction out of the material.

[0026] The storage trough is located on one side of the conveyor, and a filling platform 9 is provided on the top of the storage trough. A filling box 11 is installed above the filling platform and can be raised and lowered by a screw elevator 10. A lifting motor 12 for driving the screw to lift is provided on one side of the screw elevator.

[0027] The filling box is a rectangular hollow box, with the screw elevator located in the center below it. Four retractable guide posts 13 are also arranged around the screw elevator. The screw elevator, controlled by a lifting motor, allows for height adjustment of the filling box and the dispensing ports of each dispenser, thereby accommodating the filling of packaging barrels of varying heights. The four retractable guide posts are primarily used to ensure the lifting, sliding guidance, and auxiliary support balance of the filling box. The screw elevator, also known as a turbine screw elevator, and the retractable guide posts utilize existing technology, and their specific configuration will not be detailed here.

[0028] Four fillers are provided in the filling box, and the four fillers are arranged in sequence from front to back along the conveying direction of the conveyor. The conveyor is located directly below each filler, and four filling stations corresponding to the number of fillers are provided on the conveyor. Four induction electric eyes 14 for detecting packaging barrels are correspondingly provided on the frame of the conveyor at each filling station.

[0029] The sensor eyes are photoelectric switches, and the packaging barrels are upright, open-top cylindrical barrels. By adjusting the sensing distance of the sensor eyes, when all four sensors detect a barrel, it indicates that the barrels are directly below the discharge ports of the four fillers. At this point, the detection signal is transmitted to the electronic control box, which controls the roller conveyor to stop conveying, and then filling can begin.

[0030] The injector includes a vertical cylindrical injection barrel 15 and a sliding piston 16 that can be pushed and pulled inside the injection barrel. A suction port 17 is provided on the lower side wall of the injection barrel, and a discharge port 18 is provided at the bottom of the injection barrel. The suction port extends to the bottom of the storage tank through a suction pipe 25, and the discharge port is placed directly above the packaging barrel. The suction port and the discharge port are respectively provided with a one-way valve structure 19, and a servo electric cylinder 20 for pushing and pulling the sliding piston is connected above the sliding piston.

[0031] The one-way valve structure of the suction port and the one-way valve structure of the discharge port have opposite working directions. When the servo electric cylinder pulls the piston upward, the syringe is in a negative pressure state. At this time, the one-way valve structure of the suction port opens, and the one-way valve structure of the discharge port closes, and the paint slurry is sucked from the storage tank into the syringe; conversely, when the servo electric cylinder pushes the piston downward, the one-way valve structure of the suction port closes, and the one-way valve structure of the discharge port opens, and the paint slurry in the syringe is squeezed out and poured into the packaging barrel. The one-way valve structure and the servo electric cylinder both use existing technology, and the specific settings will not be described in detail here. The reason for using a servo electric cylinder is that its telescopic stroke and speed are easier to accurately control than those of an air cylinder. By adjusting the injection frequency and injection stroke of the injector, the paint filling amount of a single barrel can be accurately controlled and measured.

[0032] A horizontally telescopic material receiving box 21 is provided below the filling box near the discharge port of each injector. The bottom of the material receiving box is connected to the material storage tank through a recovery pipe 26. The two ends of the material receiving box are respectively connected to a horizontally arranged telescopic cylinder 22, which is connected to the bottom of the filling box through a connecting seat 23.

[0033] After one round of paint pouring, before the conveyor continues to transport the next batch of packaging barrels to their place, control the material receiving box to extend to the bottom of the pourer discharge port to catch the residual paint dripping down. Before starting the next round of paint pouring, control the material receiving box to retract and completely release the pourer discharge port to avoid interfering with the pourer's re-pouring.

[0034] An electrical control box 24 is provided on one side of the filling station. The sensor, conveying motor, lifting motor, and servo electric cylinder are all electrically connected to the box. The solenoid valve assembly (not shown) that controls the telescopic cylinder of the receiving box is also electrically connected to the box. This allows for interlocking control of the telescopic cylinder, servo electric cylinder, and conveying motor. The box and its internal control circuitry utilize existing technology, and the detailed configuration will not be detailed here.

[0035] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to ordinary technicians in this technical field. Any technical deformation made within the spirit and principles of the present invention falls within the scope of protection of the present invention.
