Description

Technical Field

[0001] The utility model belongs to the technical field of paint filling, and in particular relates to automatic paint discharging, weighing and filling equipment. Background Art

[0002] Paint filling is the process of filling finished paint into small barrels for easy sales and transportation. However, due to the high viscosity of the paint, the discharge pipe is generally fixed in size. The fast filling speed will cause impact on the paint in the barrel, introduce bubbles during the filling process, affect product quality, and affect the filling speed. At the same time, it is difficult to accurately control the filling weight, and there is often a large weight fluctuation range, resulting in high labor costs, low production efficiency, and a large weight control fluctuation range. Utility Model Content

[0003] In order to overcome the above-mentioned deficiencies, the inventor of the present utility model has continuously reformed and innovated through long-term exploration and attempts, multiple experiments and efforts, and proposed a paint automatic discharging, weighing and filling equipment, which uses a discharging structure with a first discharge port and a second discharge port for filling. The diameter of the first discharge port is larger, which can achieve rapid filling and is closed when the weight is about to reach the preset weight. The diameter of the second discharge port is smaller, and it can be used for continuous filling until it reaches the preset weight and is closed. Since the diameter of the second discharge port is smaller and closes quickly, accurate weight control can be achieved after calculating the remaining amount of paint that has not fallen into the air. A weighing mechanism is set up, which can give timely warnings when the filling weight does not meet the standard, and make timely adjustments to the production line. The dragon blade is used for paint transportation, which can adapt to paints of various viscosities. Paints with higher viscosities can also be fully discharged and are not easy to clog.

[0004] To achieve the above objectives, the present invention employs a technical solution: providing an automatic discharging, weighing, and filling device for coatings. The device comprises a discharging mechanism, a conveying mechanism, and a weighing mechanism. The discharging mechanism is located above the conveying mechanism, and the weighing mechanism is located below the conveyor belt of the conveying mechanism. The discharging mechanism comprises a hopper, a discharge on-off valve, a first discharge port, and a second discharge port. The hopper is connected to a feed pipe, and the first and second discharge ports are located at the bottom of the hopper. Each of the first and second discharge ports is provided with a discharge on-off valve.

[0005] According to the automatic discharging, weighing and filling equipment for paint described in the utility model, its further preferred technical solution is: a spiral feeding mechanism is provided on the feed pipe, a dragon blade is provided in the feed pipe, the dragon blade is connected to the blade motor, the blade motor is connected to the frequency converter to control its speed to adjust the feeding speed, and the feeding port is vertically connected to the feed pipe.

[0007] According to the automatic coating material discharging, weighing and filling equipment described in the present invention, a further preferred technical solution is that the conveyor belt is driven by a plurality of parallel rollers, and the rollers are connected to a transmission motor.

[0008] According to the automatic coating discharging, weighing and filling equipment described in the present invention, a further preferred technical solution is that the weighing mechanism is arranged at the lower part of the drum corresponding to the position of the discharging mechanism, and the weighing mechanism adopts a pressure sensor.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0025] Example:

[0026] like Figure 1 Figure 2 As shown, a coating automatic discharging, weighing and filling device. It includes a discharging mechanism 1, a conveying mechanism 2, and a weighing mechanism 3. The discharging mechanism 1 is located above the conveying mechanism 2, and the weighing mechanism 3 is located below the conveyor belt of the conveying mechanism 2. The discharging mechanism 1 includes a hopper 101, a discharge switch valve, a first discharge port 102, and a second discharge port 103. The hopper 101 is connected to a feed pipe. The first discharge port 102 and the second discharge port 103 are located at the bottom of the hopper 101. The first discharge port 102 and the second discharge port 103 are both provided with a discharge switch valve. The inlet 5 of the feed pipe is connected to a large storage tank or The transport tank connection is used to feed the filling line, and the feed pipe feeds the hopper 101. The hopper 101 mainly plays the role of temporary storage and the role of adjusting the filling speed. The first discharge port 102 and the second discharge port 103 of the feed hopper 101 are all opened during the initial filling to achieve rapid filling. When the predetermined weight is about to be reached, the larger first discharge port 102 is closed, and then the second discharge port 103 is used for filling alone. At this time, the weight can be controlled more conveniently, and the slower filling speed can make it easier to control the filling weight and control the error.

[0027] A spiral feeding mechanism 4 is provided on the feed pipe, and a Jiaolong blade 401 is provided in the feed pipe. The Jiaolong blade 401 is connected to the blade motor 402, and the feed port 5 is vertically connected to the feed pipe. The speed of the blade motor is controlled by the frequency converter to achieve fast or slow feeding. The spiral feeding can be used to transport coatings of different viscosities without blockage or transportation difficulties. Of course, the Jiaolong blade 401 here can be replaced by other similar structures.

[0028] A filter device 6 is provided above the hopper 101 in the feed pipe. The filter device 6 is a tubular screen. The outer diameter of the tubular screen is 1mm-2mm smaller than the inner diameter of the feed pipe. The tubular screen is actually located at the end of the feed pipe. An end cover is provided at the end of the feed pipe. A handle is provided on the end cover. The end cover is connected to the feed pipe with a connecting chuck. The tubular screen can be cleaned or replaced by removing the end cover to ensure the filtering effect.

[0029] The conveyor belt is driven by a plurality of parallel rollers 201, which are connected to a transmission motor 202. The barrels filled with paint can be conveyed by rotating the rollers 201, and can be paused by stopping the rotation of the rollers 201. The rollers 201 operate independently, so that the rear barrels on the conveyor belt can be continuously conveyed without being interfered by the front barrels.

[0030] The weighing mechanism is arranged at the lower part of the roller 201 corresponding to the position of the discharge mechanism 1. The weighing mechanism adopts a pressure sensor, which is a relatively simple weighing method. It only needs to set the roller 201 on the pressure sensor to achieve weighing. Of course, other weighing methods can also be used, such as liquid level detection or tension detection, which will not be repeated here.

[0031] Two conveyor mechanisms 2 are arranged in parallel, each equipped with a corresponding discharge mechanism 1 and weighing mechanism 3. The two conveyor mechanisms 2 operate independently. When both are running simultaneously, any line can discharge barrels as soon as weighing is completed, without waiting for the other line. Each line can also operate independently. During production, the desired coordination of the conveyor mechanisms 2 can be flexibly configured, enabling multi-line filling or single-line filling.

[0032] A first discharge opening and closing valve 104 and a second discharge opening and closing valve 105 are respectively provided on the first discharge port 102 and the second discharge port 103 . The first discharge opening and closing valve 104 and the second discharge opening and closing valve 105 operate independently, so that each discharge port can be operated independently.

[0033] An infrared sensor 203 is provided at the position of the conveying mechanism 2 corresponding to the discharge mechanism 1 for detecting the position of the barrel. After the barrel is in place, filling can be carried out to ensure that the paint will not leak when the barrel is missing.

[0034] A PLC controller and a matching touch screen control panel are provided. The PLC controller is electrically connected to the discharge mechanism 1, the conveying mechanism 2, and the weighing mechanism 3. The PLC controller is connected to the alarm device and a deviation alarm can be set. In fact, the PLC controller is used to control the operation of the entire equipment. The PLC controller is connected to the host computer (touch screen control panel) to receive instructions and exchange data to realize mechanized filling.

[0035] Support feet 204 are provided at the bottom of the conveying mechanism 2 for adjusting the height to ensure that the conveying mechanism 2 is level.
