Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cleaning, and particularly relates to an oil removal device for plastic parts. Background Art

[0002] Plastic parts refer to various components or products made of plastic materials. There are many types of plastic materials, including polypropylene (PP), polyethylene (PE), polystyrene (PS), polyimide (PI), polycarbonate (PC), etc. Due to their different physical and chemical properties, these materials have different applications in various fields.

[0003] The oil stains on plastic parts may come from lubricating oil, rust preventives during the production process, or oil stains during use. Therefore, an oil removal device for plastic parts is required.

[0004] Chinese Patent Publication No. CN219273890U discloses an oil removal device for plastic parts, including a turntable. The front side of the turntable is rotationally fixed with a placement mechanism through a sleeve shaft. There are four groups of the placement mechanisms and they are circumferentially arrayed around the turntable. The provided oil removal device for plastic parts, by setting the turntable and the placement mechanism, rotates the plastic parts into the cleaning tank for soaking and oil removal by placing the plastic parts inside the placement mechanism and then rotating the turntable. After oil removal, the plastic parts are moved above the conveyor belt under the continuous rotation of the turntable. Then, the placement mechanism is opened to make the plastic parts fall onto the surface of the conveyor belt and be conveyed to the subsequent workstations. The whole process is compact and can realize continuous soaking and oil removal, thus effectively improving the oil removal efficiency of plastic parts. By setting a toothed ring and a second gear, the placement mechanism can rotate around the turntable and can also rotate itself, so that the plastic parts in the placement mechanism are flipped.

[0005] The above patent still has the following defects in the implementation process:

[0006] 1. The oil removal effect is not complete by rotating the cleaning tank to remove oil from the surface of plastic parts, and there may still be oil stains remaining on the surface of plastic parts.

[0028] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0029] As Figure 1 and Figure 2 shown, an oil removal device for plastic parts includes an outer shell 1. On both sides of the left end of the outer shell 1, protection plates 8 are symmetrically and fixedly connected. On the left front middle part of the front protection plate 8 among the two protection plates 8, an air duct device 11 is fixedly connected. The outer shell 1 and the base 10 are fixedly connected together at the bottom of the two protection plates 8. At the front and rear tops of the outer shell 1 and the two protection plates 8, support rods 2 are respectively fixedly connected. A storage mechanism 3 is fixedly connected together between the two support rods 2. A drainage opening 9 is opened on the upper side of the front end of the outer shell 1. The drainage opening 9 is parallel to the left part of the front protection plate 8. The left ends of the two protection plates 8 are fixedly connected together with an oven 4. Two fans I 5 are fixedly connected in the rectangular holes opened at the top of the oven 4. A number of fans II 7 are fixedly connected together between the oven 4 and the base 10. A storage box 6 is slidably connected to the left end of the base 10. A conveyor device 13 is fixedly connected to the middle part of the left side of the rear end of the base 10. A sorting mechanism 16 and a dispersion device 15 are respectively rotatably connected to the lower left part of the rear end and the upper middle part of the rear end of the rear protection plate 8.

[0030] This solution adopts ultrasonic cleaning technology, which can clean plastic parts faster and better.

[0031] Ultrasonic cleaning generates a certain frequency and voltage signal through an ultrasonic sound source, driving the transducer and the bottom steel plate to vibrate at a high frequency. When the vibration is transmitted to the water, it will change the pressure balance in the water to form a low-pressure area and generate many tiny bubbles. These bubbles will spread along the vibration direction, and some bubbles will land on the product to be cleaned or enter the product gaps. The shock waves generated by the rupture of countless bubbles can make the dirt on the product fall off to achieve the purpose of cleaning.

[0032] Before implementing this solution, clean water and degreaser need to be added inside the housing 1. Under the condition of ultrasonic cleaning, the degreaser can better clean plastic parts.

[0033] After placing the plastic parts inside the storage mechanism 3, lower the storage mechanism 3, turn on the switch button 12 to make the ultrasonic tube 14 start working to clean the plastic parts. After cleaning, raise the storage mechanism 3 and then push the storage mechanism 3 between the protection plates 8. Under the action of the air duct device 11, the plastic parts can be slightly blown, and the plastic parts in the storage mechanism 3 are released. Under the action of the air duct device 11, the plastic parts can be slightly blown and the surface clear water is initially air-dried. Then, under the action of the dispersion device 15 and the sorting mechanism 16, the plastic parts pass through one after another and enter the oven 4. The clear water on the surface of the plastic parts is dried by the fan one 5 and the fan two 7 installed in the oven 4, and then the plastic parts are conveyed to the storage box 6 through the conveying device 13 for convenient unified collection.

[0034] In the above, a drain hole 9 is provided in the base 10 to uniformly discharge the clear water of the plastic parts on the air duct device 11.

[0035] In the above, the transducer refers to a device that converts electrical energy and sound energy into each other, and is widely used in various devices and instruments, such as echo sounders, Doppler loggers, acoustic correlation loggers, the housing 1, etc.

[0036] In the above, the support rod 2 is composed of three steel pipes and has a strong supporting effect, which can ensure that the storage mechanism 3 will not fall during use.

[0037] In the above, the air duct device 11 can be used by an external related device, such as an air duct machine, a pneumatic tube, etc.

[0038] In the above, the fan one 5 and the fan two 7 are prior arts and play a role in drying in this device.

[0039] For the specific usage method of the storage mechanism 3, refer to Figure 4 and Figure 6, the storage mechanism 3 includes a lifting mechanism 33 and a railing frame 32. The lifting mechanism 33 and the railing frame 32 are located between the outer shells 1. A pull rod 34 is fixedly connected to the front end of the lifting mechanism 33. A railing plate 31 is rotatably connected to the bottom of the inner cavity of the railing frame 32. A fixing rod 38 is rotatably connected to the rear sides of the lower sides of the railing frame 32 and the railing plate 31. The fixing rod 38 passes through the left rear end of the rear side of the railing plate 31 and the left end of the lower side of the railing frame 32 and extends linearly to the right end of the railing plate 31 and the right end of the railing frame 32. Slide plates 35 are slidably connected to both sides of the inner cavity of the railing frame 32. A handle 36 is fixedly connected to the front end of the slide plate 35. Sliding components 37 are fixedly connected to the left and right ends of the slide plate 35 and the left and right ends of the inner cavity of the railing frame 32. The lifting mechanism 33 includes two connecting rods 331. A cross bar 333 is rotatably connected between the two connecting rods 331. The cross bar 333 passes through the middle parts of the two connecting rods 331 and extends to the right end of the connecting rod 331 on the right side. An arc-shaped plate 337 is fixedly connected to the right part of the outer surface of the cross bar 333. A connecting piece 339 and a rocker 338 are respectively fixedly connected to the left part and the right part of the right end of the arc-shaped plate 337. A fixing plate 334 is fixedly connected to the right side of the right end of the connecting rod 331 on the right side. Pulley wheels 332 are fixedly connected to the left and right sides of the outer surfaces of the two connecting rods 331 and the cross bar 333. Hook ropes 335 are wound and connected to the inner surfaces of the two pulley wheels 332. Railings 336 are fixedly connected to the tops of the left and right parts of the railing frame 32.

[0040] In the above, the railing plate 31, the railing frame 32, and the slide plate 35 can all be made of aluminum plates.

[0041] After putting the plastic parts inside, by rotating the rocker 338, the arc-shaped plate 337 is driven to move. The arc-shaped plate 337 drives the cross bar 333 to rotate in sequence, and then drives the pulley wheels 332 installed on the left and right parts of the outer surface of the cross bar 333 to rotate. The pulley wheels 332 drive the wound and connected hook ropes 335. Under the principle of the pulley wheels 332, the hook ropes 335 extend downward, and the railing plate 31, the railing frame 32, and the slide plate 35 slide downward evenly into the inside of the outer shell 1 to clean the plastic parts. After the cleaning is completed, the hook ropes 335 are used to pull the railings 336 to take out the railing plate 31, the railing frame 32, and the slide plate 35, and the plastic parts inside. The rocker 338 is placed in the buckle opened on the fixing plate 334 to ensure that the lifting mechanism 33 will not fall freely. Then, by dragging the pull rod 34, the device is moved above the dispersing device 15. Then, by pulling the handle 36, the slide plate 35 is pulled out. Under the condition of gravity and the action of the installed fixing rod 38, the railing plate 31 will open downward with the fixing rod 38 as the center, and the plastic parts will fall into the protection plate 8.

[0042] In the above, sliding components 37 are installed at the left and right ends of the slide plate 35. The sliding components 37 are composed of two sliders that are mutually engaged, and the slide plate 35 can be smoothly pulled out.

[0043] In the above, it is recommended that the hook rope 335 be made of materials with good tensile strength and elasticity, such as nylon ropes, etc.

[0044] In the above, connecting pieces 339 are fixedly installed at both ends of the lifting mechanism 33, which can prevent the cross bar 333 in the lifting mechanism 33 from falling off during operation.

[0045] Specifically, for the purpose of sorting and dispersing plastic parts, refer to Figure 3 and Figure 5 , the dispersing device 15 includes a transmission rod 152, the transmission rod 152 is located at the left rear end of the rear protection plate 8, a third pulley 151 is fixedly connected to the outer surface of the rear part of the transmission rod 152, a third pulley 151 is fixedly connected to the outer surface of the rear part of the right roller shaft 133, a transmission belt is rotatably connected between the two third pulleys 151, a rotary brush 154 is fixedly connected to the front end of the transmission rod 152, the sorting mechanism 16 includes a second motor 161, the second motor 161 is located at the rear of the protection plate 8, a cylindrical rod 163 is fixedly connected to the output end of the second motor 161, a dial 162 is fixedly connected to the outer surface of the rear part of the cylindrical rod 163, a top plate 164 is arranged on the upper part of the dial 162, a U-shaped plate 166 is fixedly connected to the rear end of the top plate 164, a conical plate 165 is fixedly connected to the front end of the upper half of the U-shaped plate 166, and the U-shaped plate 166 is rotatably connected to the rear end of the water draining rack 153.

[0046] In the above, after the plastic parts fall on the surface of the water draining rack 153, they enter the air inlet 111 and are blown into the air box 112 to preliminarily sort the plastic parts. Then, the power generated by the third pulley 151 drives the transmission rod 152 to rotate through the transmission belt, and the transmission rod 152 drives the rotary brush 154 to rotate to separate the plastic parts adhered due to moisture. Due to the slope treatment of the water draining rack 153, the plastic parts will slide due to inertia.

[0047] Similarly, when the second motor 161 drives the cylindrical rod 163 to rotate through the coupling, the cylindrical rod 163 drives the dial 162 to rotate. When the raised blocks arranged on the dial 162 rotate, the raised blocks will lift the U-shaped plate 166 for a small movement. The U-shaped plate 166 will also drive the top plate 164 and the conical plate 165 for a small movement, which can limit the passage of single plastic parts and block the passage of the subsequent plastic parts. When in a static state, the conical plate 165 will block the passage of plastic parts. When the dial 162 rotates, the conical plate 165 moves upward, allowing a single plastic part to pass through, and then the top plate 164 will extend to continue blocking the subsequent plastic parts.

[0048] In the above, small holes are provided on the surface of the water draining rack 153, which can allow the clear water on the surface of the plastic parts after cleaning to flow into the water flowing groove opened below, and the clear water will be discharged from the water draining port 9 after flowing into the water flowing groove.

[0049] Specifically, to achieve the purpose of air-drying and conveying plastic parts, refer to Figure 2 and Figure 3 The conveying device 13 includes a support base 131 and two roller shafts 133. The support base 131 is fixedly connected to the left part of the rear end of the base 10. The top of the support base 131 is fixedly connected with a first motor 132. The output end of the first motor 132 is fixedly connected with a second pulley 136. The two roller shafts 133 penetrate and are rotatably connected to the left and right sides of the oven 4. The rear parts of the outer surfaces of the two roller shafts 133 are fixedly connected with first pulleys 134. A transmission belt is rotatably connected between the two first pulleys 134 and the two second pulleys 136 in the same plane. A conveying frame 135 is installed in the inner cavity of the oven 4. The conveying frame 135 is rotatably connected to the outer surfaces of the two roller shafts 133.

[0050] In the above, the first motor 132 is connected to the two second pulleys 136 through a coupling. The two second pulleys 136 drive the first pulleys 134 in the same horizontal plane to rotate through the transmission belt. The first pulleys 134 drive the roller shafts 133 fixedly connected thereto respectively. The roller shafts 133 drive the conveying frame 135 to move, moving the dried plastic parts into the storage box 6 for unified collection, which improves the working efficiency.

[0051] In the above, small holes are formed on the surface of the conveying frame 135. First, it is convenient for the clear water on the surface of the plastic parts not to accumulate on the outer surface of the conveying frame 135. Second, the wind generated by the second fan 7 installed can blow to the surface of the plastic parts. It should be noted that during use, the second fan 7 needs to be placed obliquely, and fixing plates need to be installed on both sides to stabilize it on both sides of the device. Then, the accumulated water on the surface of the plastic parts is dried together with the first fan 5 installed above the conveying frame 135.

[0052] It should be particularly noted that the specific installation methods, circuit connection methods, and control methods of the first motor 132 and the second motor 161 adopted in the present invention are all conventional designs, and the present invention will not elaborate in detail.

[0053] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
