Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a high-efficiency cleaning device for powder injection molding. Background Technology

[0002] The existing technology makes it difficult to securely fix the workpiece, and the cleaning angle and water pressure are not ideal, resulting in incomplete and inadequate cleaning. The wastewater collection and discharge design is poor, which easily leads to wastewater residue and splashing, polluting the environment. There is a lack of effective measures to treat impurities in the air and wastewater, and components such as vacuum pumps are easily damaged, shortening the service life of the equipment. Moreover, the angle and position of the cleaning device are fixed, which cannot meet the cleaning needs of different workpieces and has poor versatility. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency cleaning device for powder injection molding to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device that can slide on an inclined annular slide rail, a spiral fan blade that can separate excess moisture and impurities in the air, and the high-efficiency cleaning device for powder injection molding further includes a cleaning table, a confluence bottom, a bowl-shaped groove, a cleaning device, an electric rotating shaft, and a support column.

[0005] The cleaning table is used to place and fix the workpieces that need to be cleaned. Several honeycomb-shaped air intakes are evenly opened on the cleaning table, and several suction cups for adsorbing the workpieces are fixed on the cleaning table.

[0006] The confluence bottom is used to collect the wastewater generated during the cleaning process, and the wastewater is introduced into the annular buffer tank through the diversion channel opened on the confluence bottom;

[0007] The bowl-shaped groove is provided with an inclined annular slide rail near the bottom, and a slider is slidably mounted on the inclined annular slide rail.

[0008] The cleaning device is supplied with water by a water pump below it. The water pump draws the cleaning water that enters the diversion pipe from the inlet. After the water is pressurized by the first inlet pipe with a large opening at the bottom and a small opening at the top, it is sprayed out from the nozzle of the cleaning device.

[0009] The electric rotating shaft is used to adjust the angle of the entire cleaning device. The electric rotating shaft is mounted on the slider, and the slider has a motor inside for driving the electric rotating shaft.

[0010] The support column is used to support the inner nozzle. The support column is connected to the bottom of the inner nozzle by a rotating component. Under the action of the water flow in the second water inlet pipe inside the support column, there is an inclined force on the bottom of the inner nozzle, causing the inner nozzle to rotate relative to the support column.

[0011] Preferably, the top of the spiral fan blade is connected to the middle position of the filter element, and the filter element is provided above the spiral fan blade for preliminary filtration of gas or sewage impurities entering the lower air intake pipe through the honeycomb-shaped air intake port.

[0012] The spiral fan blades are installed inside the air intake column, and a temporary annular collecting groove is provided inside the air intake column. The temporary annular collecting groove is used to temporarily store the impurities thrown out by the rotation of the spiral fan blades, and then enter the wastewater pipe through the through hole provided at the bottom of the temporary annular collecting groove.

[0013] Preferably, a small valve is installed in the wastewater pipe.

[0014] Preferably, the inclined annular slide rail below the cleaning device is provided with an annular groove, and the top of the first water inlet pipe is connected to the annular groove.

A pressure boosting pipe is provided above the hollow groove to increase the water pressure.

[0016] Preferably, the top of the inner nozzle is provided with a fixing member for rotatably connecting with the fixing groove at the bottom of the outer nozzle located above the inner nozzle;

[0017] When the fixing member and the fixing groove are engaged by rotation, the pressurizing pipe engages with the notch at the bottom of the outer nozzle, so that the two fit together and prevent water leakage.

[0018] Preferably, the connecting plate where the notch is located is provided with two fixing posts, and a blocking element is slidably provided on the fixing posts.

[0019] Preferably, the top of the buffer tank has two inlet troughs that introduce water flow into the nozzle.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The suction cups and honeycomb-shaped air intakes of the cleaning station securely fix the workpiece. The inner nozzles rotate under the action of water flow from the support column, and the pressure booster pipe increases the water pressure, spraying high-pressure water from the nozzles to clean the workpiece from multiple angles.

[0022] 2. The confluence bottom and bowl-shaped trough effectively collect sewage, which is then introduced into the annular buffer tank through the diversion channel and discharged through the drain outlet, avoiding sewage residue and splashing;

[0023] 3. The spiral fan blades and filter elements work together to filter gas impurities, and the small valve on the wastewater pipe prevents sewage backflow and protects components such as the vacuum pump, thus making up for the shortcomings of traditional devices where impurities can easily damage the equipment.

[0033] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Please see Figure 1-7This utility model provides a technical solution: a high-efficiency cleaning device for powder injection molding, including a cleaning device 12 that can slide on an inclined annular slide rail 13, a spiral fan blade 21 that can separate excess moisture and impurities in the air and thus avoid damage to the vacuum pump 9, and the high-efficiency cleaning device for powder injection molding also includes a cleaning table 4, a confluence bottom 8, a bowl-shaped groove 2, a cleaning device 12, an electric rotating shaft 17, and a support column 16.

[0035] The cleaning table 4 is used to place and fix the workpieces that need to be cleaned. Several honeycomb-shaped air intakes 23 are evenly opened on the cleaning table 4, and several suction cups 24 are fixed on the cleaning table 4 to enhance the adsorption of the workpieces.

[0036] The collection bottom 8 is used to collect the sewage generated during the cleaning process, and introduce the sewage into the annular buffer tank 82 through the diversion channel 81 opened on the collection bottom 8, and discharge it out of the device through the drain outlet 5.

[0037] The bowl-shaped trough 2 collects and centrally treats the water generated during the cleaning process, while preventing sewage from splashing outside the device. The bowl-shaped trough 2 is provided with an inclined annular slide rail 13 near the bottom, and a slider 14 is slidably mounted on the inclined annular slide rail 13.

[0038] The cleaning device 12 is supplied with water by the water pump 11 below it. The water pump 11 draws the cleaning water that enters the diversion pipe 10 from the water inlet 7. After the water is pressurized by the first water inlet pipe 15 with a large opening at the bottom and a small opening at the top, it is sprayed out from the nozzle 28 of the cleaning device 12 to clean the workpiece.

[0039] The electric rotating shaft 17 is used to adjust the angle of the entire cleaning device 12. The electric rotating shaft 17 is mounted on the slider 14, and the slider 14 has a motor inside to drive the electric rotating shaft 17.

[0040] The support column 16 is used to support the inner nozzle 18. The support column 16 is connected to the bottom of the inner nozzle 18 by a rotating component (such as a bearing). Under the action of the water flow in the second water inlet pipe 181 inside the support column 16, there is an inclined force on the bottom of the inner nozzle 18, which causes the inner nozzle 18 to rotate relative to the support column 16, so as to achieve efficient cleaning.

[0041] The top of the spiral fan blade 21 is connected to the middle of the filter element 22. The filter element 22 is provided above the spiral fan blade 21 for preliminary filtration of gas or sewage impurities entering the lower air intake pipe through the honeycomb air intake port 23.

[0042] The spiral fan blade 21 is installed inside the air intake column, and a temporary annular collecting groove 20 is provided inside the air intake column to temporarily store the impurities thrown out by the rotation of the spiral fan blade 21, and then enter the wastewater pipe 19 through the through hole provided at the bottom of the temporary annular collecting groove 20.

[0043] A small valve is installed in the wastewater pipe 19 to prevent sewage impurities accumulated in the annular buffer tank 82 from flowing back into the temporary annular collection tank 20 from the wastewater pipe 19.

[0044] The inclined annular slide rail 13 below the cleaning device 12 has an annular groove inside, and the top of the first water inlet pipe 15 is connected to the annular groove.

[0045] The bottom of the support column 16 of the cleaning device 12 is connected to the electric rotating shaft 17. The bottom of the inner nozzle 18 is provided with a hollow groove, which is used to rotate the inner nozzle 18 in conjunction with the water flow. A booster pipe 182 is provided above the hollow groove to enhance the pressure of the cleaning water.

[0046] The top of the inner nozzle 18 is provided with a fixing member 25, which is used to rotatably connect with the fixing groove 251 at the bottom of the outer nozzle located above the inner nozzle 18;

[0047] When the fixing member 25 and the fixing groove 251 are engaged by rotation, the pressurizing pipe 182 engages with the notch 183 at the bottom of the external nozzle, so that the two fit together and prevent water leakage.

[0048] The connecting plate where the notch 183 is located is provided with two fixing posts 261, and a blocking member 26 is slidably arranged on the fixing post 261; the sliding arrangement here is because the connecting plate is provided with a hole that matches the fixing post 261.

[0049] When the water flows in from below, the blocking member 26 is pushed upward by the water flow, the buffer groove 271 opens, and the blocking member 26 moves to the top position of the fixed column 261.

[0050] When no water flows into the inner nozzle 18, there is no water flow in the booster pipe 182. The blocking member 26, located at the bottom of the fixed column 261, seals the notch 183. When water is introduced, the water flow pushes the blocking member 26 upward, allowing the water to flow smoothly through the notch 183 into the buffer tank 271. After being guided by the water inlet tank 27, the water is introduced into the nozzle 28 and sprayed out. Here, the blocking member 26 can maintain stable water pressure and prevent sewage backflow. Sensors can be added as needed to detect whether sewage backflow occurs and automatically lower the blocking member when this happens.

[0051] Two water inlet grooves 27 are provided on the top of the buffer tank 271 to introduce water flow into the nozzle 28. The water flow is pressurized when it passes through the nozzle 28. The pressurization is also due to the relatively small size of the nozzle 28, which promotes cleaning.

[0052] In actual operation, the workpiece to be cleaned is placed on the cleaning table 4 and firmly adsorbed using the suction cup 24 and honeycomb-shaped air intake 23. The water pump 11 is started, and cleaning water enters the diversion pipe 10 from the inlet 7, is pressurized by the first inlet pipe 15, and then enters the cleaning device 12. The motor drives the electric rotating shaft 17, adjusting the angle of the cleaning device 12. Simultaneously, the slider 14 is controlled to rotate and move on the inclined annular slide rail 13, performing multi-directional cleaning of the workpiece. The water flow in the second inlet pipe 181 inside the support column 16 causes the inner nozzle 18 to rotate, and cleaning water is sprayed out from the nozzle 28 to clean the workpiece. Wastewater flows into the annular buffer tank 82 through the drainage channel 81 of the confluence bottom 8 and is discharged from the drain outlet 5. The spiral fan blade 21 and filter element 22 filter gas impurities.

[0053] If sewage backflow is detected during the cleaning process, the sensor controls the blocking component 26 to descend and block the notch 183. Without adding new sewage, the workpiece is removed and the previously closed water pump 11 is turned on again to restart the cleaning device. After the backflowed sewage is discharged, the operation continues to ensure the cleaning effect of the workpiece.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
