Description

Technical Field

[0001] This utility model relates to the field of plastic masterbatch processing equipment, specifically an automatic dust removal plug. Background Technology

[0002] In the production process of preparing plastic masterbatch, plastic powder (i.e., masterbatch) needs to be mixed with different types of additives and stirred thoroughly. After heating, it is extruded and molded to prepare plastic masterbatch with different ratios and obtain plastic masterbatch with different properties. In the process of use, these modified plastic masterbatches are added to the injection molding machine or added to other plastics for use.

[0003] In existing technologies, different mixing devices are required in the production process of plastic masterbatch to achieve high-quality masterbatch. In the mixing process of powder and coarse materials, various fine powders and additives are first added to a powder mixing tank for mixing. The outlet of the powder mixing tank is connected to a second mixing tank. Opening the outlet of the powder mixing tank allows for easy discharge and cleaning. After the powder in the powder mixing tank is thoroughly mixed, the stopper of the powder mixing tank needs to be opened to allow the mixed fine powder to flow into the second mixing tank for further mixing with the granules. When opening the stopper of the powder mixing tank, the stopper of the second mixing tank must be opened first. The manual door allows you to open the stopper of the powder mixing tank from the wall of the second mixing tank and release the mixed powder. However, opening the stopper causes a lot of powder to splash out of the door, resulting in powder splattering. After closing the door and releasing the powder, you have to wait for the splashed powder in the second mixing tank to settle before you can open the door again, plug the stopper, and start the second mixing tank again. This process is time-consuming and troublesome. In addition, the inner wall of the discharge port is covered with powder, making it impossible to directly install the stopper. You have to open the door and use a cleaning brush or air gun to clean the powder around the discharge port before you can plug the stopper. This cleaning process also causes powder splattering, which is troublesome and inconvenient. Summary of the Invention

[0004] In the process of producing plastic masterbatch using existing equipment, when the plug of the powder mixing tank is opened, a large amount of splashed powder flies out from the manual door, causing powder splattering. After closing the manual door and discharging the powder, it is necessary to wait for the splashed powder in the second mixing tank to settle before the manual door can be reopened and the plug closed. In addition, the inner wall of the discharge port after discharge will be covered with powder, making it impossible to directly install the plug. It is necessary to open the manual door and use a cleaning brush or air gun to clean the powder around the discharge port before plugging the plug. However, cleaning will cause powder to splash again, which is troublesome and inconvenient. This application provides an automatic dust removal plug, which is equipped with an automatic control mechanism and an air blowing device. It can automatically control the opening and closing of the plug of the powder mixing tank without opening the manual door. The automatic control mechanism is equipped with an air blowing device that can clean the powder adhering to the inner wall of the discharge port and then automatically plug the plug. It is more convenient and effective in use. There is no need to open the manual door or manually clean the powder adhering to the inner wall of the discharge port, and it can also prevent powder from splashing out of the workshop and causing dust pollution.

[0005] The technical solution adopted by this utility model to solve the technical problem is: an automatic dust removal plug, including an automatic control mechanism, an air blowing device, and a plug. The automatic control mechanism is equipped with an air blowing device that can remove dust from the inner wall of the discharge port. The automatic control mechanism includes a frame, a telescopic cylinder, and a plug. The frame is fixedly installed at the front end of the discharge port of the powder mixing tank. The telescopic cylinder is provided in the frame, and the front end of the telescopic rod of the telescopic cylinder is provided with a plug that can be inserted into the discharge port. When the telescopic rod of the telescopic cylinder extends, the plug is inserted into the discharge port to seal the discharge port of the powder mixing tank. When the telescopic rod of the telescopic cylinder retracts, the discharge port of the powder mixing tank opens, and the powder in the powder mixing tank can be discharged into a second mixing tank. The plug of the powder mixing tank can be automatically opened or closed without opening the manual door of the second mixing tank, avoiding the problem of a large amount of splashed powder flying out of the doorway when the manual door is opened and then the plug is opened, which would cause powder to splash out of the workshop.

[0006] The air blowing device includes a dust removal frame and an air jet nozzle. The dust removal frame is set at the front and rear ends of the automatic control mechanism frame, and the air jet nozzle is set in the dust removal frame. The air jet nozzle is connected to the air supply pipe. The air jet nozzle can blow air to remove dust from the inner wall of the discharge port of the powder mixing tank, blow away the powder adhering to the inner wall of the discharge port, so that the plug can better seal the discharge port and prevent the inner wall of the discharge port from being stuck with powder and unable to be plugged.

[0007] The air supply pipe of the air blowing device is connected to the pneumatic control module. Pressing the switch of the pneumatic control module controls the air jet of the air blowing device to spray air and clean the inner wall of the discharge port. This allows the air blowing device to clean the powder adhering to the inner wall of the discharge port, and then the automatic control mechanism controls the movement of the plug to seal the discharge port. There is no need to manually clean the powder adhering to the inner wall of the discharge port, nor is there a need to manually plug the plug, making it more convenient to use and providing a better sealing effect.

[0008] The telescopic cylinder of the automatic control mechanism is connected to the control module, and the telescopic rod of the telescopic cylinder is extended or retracted by the button of the control module.

[0009] The telescopic cylinder of the automatic control mechanism can be any one of a hydraulic telescopic cylinder, an electric telescopic cylinder, or a pneumatic telescopic cylinder.

[0010] The air blowing device can be installed in the plug cover, including the plug cover, air jets, and air delivery pipe. Several forward-sloping air jets are arranged around the periphery of the plug cover. The air jets are connected to the air delivery pipe. When gas is introduced into the air delivery pipe, the gas is ejected from the air jets, which can remove dust and clean the powder adhering to the inner wall of the discharge port.

[0011] The plug of the air blowing device has four rectangular air nozzles around its perimeter. The angle between the air nozzles and the horizontal direction directly in front is 5-35 degrees, preferably 15 degrees, so that the gas can be better sprayed onto the inner wall of the discharge port.

[0012] The beneficial effects of this utility model are: an automatic dust removal plug, wherein the automatic control mechanism is equipped with an air blowing device, which can remove dust from the inner wall of the discharge port. The automatic control mechanism can control the plug of the powder mixing tank to open or close automatically. By combining the automatic control mechanism and the air blowing device, the plug of the powder mixing tank can be automatically controlled to open or close without opening the manual door. The air blowing device on the automatic control mechanism can remove dust from the powder adhering to the inner wall of the discharge port and then automatically plug the plug. It is more convenient to use and the sealing effect is better. It is more effective and does not require opening the manual door or manually cleaning the powder adhering to the inner wall of the discharge port. It can also prevent powder from splashing out of the workshop and causing dust pollution. Attached Figure Description

[0021] exist Figure 1-2 In the existing technology shown, different stirring devices are needed for stirring and mixing in the process of producing plastic masterbatch in order to obtain high-quality plastic masterbatch. In the mixing process of powder and coarse material, various fine powders and additives need to be added to the powder mixing tank 1 for stirring and mixing. The discharge port 3 of the powder mixing tank 1 is connected to the second mixing tank 2. Opening the discharge port 3 of the powder mixing tank 1 allows for easy cleaning and discharge of the powder. After the powder in the powder mixing tank 1 is fully stirred and mixed, the stopper 4 of the powder mixing tank 1 needs to be opened to allow the mixed fine powder to flow into the second mixing tank 2 for stirring and mixing with the granules. When opening the stopper 4 of the powder mixing tank 1, the handle 6 of the second mixing tank 2 needs to be opened first before the second mixing tank 2 can be stirred and mixed. The plug 4 of the powder mixing tank 1 is manually opened on the wall 2 of the second mixing tank to release the mixed powder. At the moment the plug 4 of the powder mixing tank 1 is manually opened, a lot of powder will splash out from the door 6, causing powder to splash. After closing the door and releasing the powder, it is necessary to wait for the splashed powder in the second mixing tank 2 to settle before the door 6 can be opened again to plug the plug 4, and then the second mixing tank 2 can be started again for mixing. This step is time-consuming and troublesome. In addition, the inner wall 5 of the discharge port 3 after discharge will be covered with powder, making it impossible to directly and easily install the plug 4 and locking pin 7. It is necessary to open the door 6 and use a cleaning brush or air gun to clean the powder around the inner wall 5 of the discharge port 3 before plugging the plug 4. Cleaning will also cause powder to splash, which is troublesome and inconvenient.

When the telescopic rod of the telescopic cylinder 8 extends, the plug 4 is inserted into the discharge port 3 to block the discharge port 3 of the powder mixing tank 1. When the telescopic rod of the telescopic cylinder 8 retracts, the discharge port 3 of the powder mixing tank 1 opens, and the powder in the powder mixing tank 1 can be discharged into the second mixing tank 2. The plug 4 of the powder mixing tank 1 can be opened or closed without opening the manual door of the second mixing tank 2. This avoids the problem of a lot of powder splashing out of the door when the manual door 6 is opened and the plug 4 is opened manually, causing powder to splash out of the workshop and causing dust pollution. It is more convenient and effective to use, without the need to open the manual door.
