Description

Technical Field

[0001] This utility model relates to the field of plastic parts cleaning, specifically to an energy-saving automatic cleaning device for injection molded parts. Background Technology

[0002] In the injection molding process, after the grinding step, a large amount of dust inevitably adheres to the outer surface of the injection molded parts. If this dust is not removed in time, it will not only affect the appearance quality of the injection molded parts, but may also adversely affect subsequent assembly and performance. Currently, the industry commonly uses electrostatic dust removal equipment to clean the surface of the injection molded parts after grinding. This equipment can efficiently remove dust through the principle of electrostatic adsorption, and has a good cleaning effect.

[0003] However, existing electrostatic dust removal equipment has obvious defects in practical applications. During operation, operators need to place small, regular injection molded parts one by one on the surface of the electrostatic dust removal conveyor belt. This manual feeding method has many problems. On the one hand, manual operation is inefficient and cannot meet the needs of large-scale production. On the other hand, during the manual feeding process, operators need to frequently come into contact with the injection molded parts, which not only increases the labor intensity, but also easily causes quality problems such as scratches and wear on the surface of the injection molded parts due to improper operation. At the same time, there are also certain safety hazards.

[0004] Therefore, there is an urgent need to develop an energy-saving injection molded parts cleaning device that can automatically feed materials, in order to solve the shortcomings of manual feeding in the existing technology and improve production efficiency and product quality.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 As shown, this utility model is an energy-saving automatic cleaning device for injection molded parts, including: a cleaning component 2, and a feeding component 1 is provided inside one end of the cleaning component 2;

[0028] The feeding component 1 includes a hopper 17, with a guide plate 15 at the bottom of the hopper 17. An arc-shaped tube 18 is connected to the bottom of the hopper 17. A feeding shaft 19 is rotatably engaged inside the arc-shaped tube 18. A transmission gear 12 is fixedly connected to one end of the feeding shaft 19. A gear shaft 110 is rotatably engaged at the bottom of the hopper 17 and below the arc-shaped tube 18. A conveyor belt 112 is uniformly sleeved on the outer surface of the gear shaft 110. A transmission sprocket 111 is fixedly installed on the outer surface of one end of the gear shaft 110. A transmission chain 13 is meshed with the outer surface of the transmission sprocket 111. A feeding shaft 11 is rotatably connected to the other end of the transmission chain 13. A drive motor 14 is fixedly connected to one end of the feeding shaft 11.

[0029] The cleaning component 2 includes a protective cover 28. An upper electrostatic precipitator 25 is installed on the top of the protective cover 28, and a lower electrostatic precipitator 23 is fixedly connected to the bottom of the protective cover 28. A cleaning channel 24 is opened in the middle of both ends of the protective cover 28. A control box 22 is installed on the side of the protective cover 28. A drive shaft 21 is installed at one end of the protective cover 28 and at the edge of the cleaning channel 24. Duct delivery interfaces 26 are provided on the outer surfaces of both the lower electrostatic precipitator 23 and the upper electrostatic precipitator 25. An alarm light 27 is fixedly installed on the top edge of the upper electrostatic precipitator 25.

[0030] The outer surfaces of both sides of the hopper 17 are provided with transparent observation ports 16, which make it easy for staff to observe the amount of injection molded parts inside the hopper 17 from the side and replenish the injection molded parts in time.

[0031] The hopper 17 is fixedly connected to the end of the protective cover 28, and can collect the injection molded parts at the upper part of one end of the protective cover 28 for discharge. The conveyor belt 112 is connected to the inside of the protective cover 28 through the cleaning channel 24, and can transport the injection molded parts between the lower electrostatic precipitator 23 and the upper electrostatic precipitator 25 for cleaning.

[0032] One end of the drive motor 14 is fixedly connected to the middle of the side of the arc tube 18, and both ends of the feeding shaft 11 are rotatably engaged with the inner sides of the cleaning channel 24, so the drive motor 14 can control the feeding shaft 11 to rotate and run.

[0033] The material feeding shaft 11 has teeth evenly arranged on its outer surface. The material feeding shaft 11 is inserted into the gap between the teeth on its outer surface and the conveyor belt 112, which can flip and adjust the injection molded parts that pass through, ensuring that the injection molded parts are completely cleaned.

[0034] The feeding shaft 19 is connected to the end of the gear shaft 110 below by a transmission gear 12 at one end. When the conveyor belt 112 rotates, the feeding shaft 19 can be synchronously controlled to rotate in the opposite direction to discharge the injection molded parts downward. The bottom end of the guide plate 15 points to the feeding shaft 19 inside the collecting hopper 17, which can make the injection molded parts descend into the feeding shaft 19 for downward discharge.

[0035] One end of the drive sprocket 111 is sleeved with the drive shaft 21, which can ensure that the conveyor belt 112 is taut and operates normally. The bottom of the upper electrostatic precipitator 25 and the top of the lower electrostatic precipitator 23 are connected to the upper and lower sides of the cleaning channel 24, so that the removed dust can be extracted.

[0036] The working principle of this utility model is as follows: After the production of small, regular injection molded parts is completed, burrs usually remain on their edges, so they need to be polished. After the polishing process is completed, these injection molded parts are poured into the collecting hopper 17. At this time, the injection molded parts will slide naturally down the inclined surface of the guide plate 15 and then enter the interior of the feeding shaft 19.

[0037] Subsequently, the operator starts the drive motor 14, the lower electrostatic precipitator 23 and the upper electrostatic precipitator 25. The electrostatic precipitators 23 and 25 begin to work together to quickly extract the air in the cleaning channel 24, creating a suitable environment for subsequent cleaning operations.

[0038] When the drive motor 14 starts running, it plays a crucial role as a power source. On one hand, the drive motor 14 drives the connected material feeding shaft 11 to rotate, and the rotation of the material feeding shaft 11 provides power for the subsequent adjustment of the injection molded part. On the other hand, the drive motor 14 drives the gear shaft 110 to rotate synchronously through the transmission chain 13. The rotation of the gear shaft 110 acts as a pivot, triggering a series of interconnected effects.

[0039] During the rotation of the gear shaft 110, the multiple sets of conveyor belts 112 sleeved on its outer surface also rotate synchronously. At the same time, the gear shaft 110 drives the feeding shaft 19 to rotate synchronously through the transmission gear 12. When the feeding shaft 19 rotates, it will drive the injection molded parts falling from the collecting hopper 17 to rotate synchronously in the arc tube 18. During this process, the injection molded parts are orderly conveyed to the upper surface of the lower conveyor belt 112.

[0040] The rotating conveyor belt 112 begins to transport the injection molded parts laterally, smoothly sending them into the cleaning channel 24. Inside the cleaning channel 24, ultrasonic electrostatic technology is used to thoroughly and meticulously clean the injection molded parts of dust.

[0041] When the injection molded part passes through the feeding shaft 11, the feeding shaft 11 will flip it. This flipping action is crucial. It allows the position of the injection molded part on the upper surface of the conveyor belt 112 to be adjusted, avoiding the problem that the dust in the overlapping part of the injection molded part and the conveyor belt 112 cannot be effectively cleaned.

[0042] The entire cleaning process is completed once the injection molded parts are conveyed away from the cleaning channel 24. It is worth mentioning that the discharge shaft 19 is composed of multiple partition plates. This unique structural design allows it to discharge the injection molded parts descending from the collection hopper 17 in batches and intermittently. In this way, the injection molded parts can be evenly placed on the upper surface of the conveyor belt 112, thereby achieving uniform cleaning of the injection molded parts.

[0043] By adding a feeding component 1 inside one end of the cleaning component 2, the automatic cleaning device for injection molded parts successfully acquires the function of automatic feeding. This innovative design effectively solves many shortcomings of manual feeding in the existing technology and significantly improves production efficiency and product quality.

[0044] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
