Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for injection molded parts, and more specifically, to an online foreign matter removal device for injection molded parts. Background Technology

[0002] After injection molded parts are produced, they usually need to be automatically screened and classified by sorting equipment. However, in the actual sorting process, the surface or interior of the injection molded parts often have foreign objects such as plastic shavings, burrs, and dust that have not been completely removed. However, existing sorting equipment generally lacks an effective online foreign object removal device, which causes these foreign objects to enter the sorting system along with the parts, especially in the vibratory feeder and conveyor channel areas, causing material jamming. That is, foreign objects such as plastic shavings are squeezed and accumulated with the parts in the vibratory feeder or conveyor channel, which can easily cause material jamming, leading to abnormal equipment shutdown, affecting sorting efficiency, and increasing maintenance costs.

[0003] Therefore, in existing technologies, additional cleaning processes are usually added, which not only increases the complexity and time of the production process, but also increases water resources, energy consumption and labor costs, and makes it impossible to directly put them into sorting equipment to achieve continuous operation.

[0004] Based on the above description, there is an urgent need for a device that can be integrated into the feeding end of sorting equipment to achieve efficient online removal of foreign objects, so as to improve the stability of the sorting process and the cleanliness of the parts, and reduce the overall production cost.

[0019] The specific implementation method is described below with reference to the accompanying drawings.

[0020] Example 1 Please see Figures 1 to 5 This utility model provides the following technical solution: an online foreign object removal device for injection molded parts sorting, which is suitable for online foreign object removal when docked with sorting equipment.

[0021] Specifically, such as Figure 1 and Figure 2 As shown, an online foreign object removal device for injection molded parts includes a conveying box 1, a pair of blower assemblies 2, and a suction assembly 3. The conveying box 1 includes an inlet end 11 and an outlet end 12. A pair of side walls of the outlet end 12 are provided with an array of ventilation holes. The pair of blower assemblies 2 are respectively located on the pair of side walls of the outlet end 12. The blower assemblies 2 are connected to the inner cavity of the conveying box 1 through the array of ventilation holes. The top of the outlet end 12 is provided with a suction assembly 3. The suction assembly 3 is located between the pair of blower assemblies 2.

[0022] In this embodiment, the cross-section of the conveying box 1 is an isosceles trapezoid. Specifically, its pair of sidewalls are inclined, which increases the area of ​​the ventilation hole array and further improves the foreign matter removal efficiency by enhancing the blowing effect. Furthermore, the discharge end 12 of the conveying box 1 is connected to the inlet end of the sorting equipment, which facilitates continuous sorting after automatic removal of foreign matter. Furthermore, in order to facilitate the smooth passage of injection molded parts through the conveying box 1, the conveying box 1 is inclined (i.e., gradually inclined from high to low, from the feeding end to the discharge end) and equipped with a commonly used material conveying vibrator.

[0023] Specifically, such as Figure 2 and Figure 3 As shown, the conveying bin 1 is provided with a telescopic rod 4 along the conveying direction; the end of the telescopic rod 4 extending towards the blower assembly 2 is provided with a material-dispensing assembly 5. The material-dispensing assembly 5 includes multiple levers 51; the multiple levers 51 are arranged at the ends of the telescopic rod 4; the multiple levers 51 are located between a pair of blower assemblies 2; and the suction assembly 3 is located at the top of the multiple levers 51.

[0024] In this embodiment, the telescopic rod 4 can be an electric push rod or a compact cylinder. To prevent the injection molded parts from being damaged by hitting the wall due to the movement of the telescopic rod 4 after being put into the conveying box 1 from the feeding end 11, a buffer pad is further provided on the box wall of the inlet end 11 of the conveying box 1. The specific material can be sponge, elastic silicone, etc. commonly used in the art, and can be selected according to actual needs.

[0025] Specifically, such as Figure 4 and Figure 5 As shown, the feeding assembly 5 also includes a plurality of feed wheels 52 disposed on the feed lever 51; the feed wheels 52 are sleeved on the feed lever 51 and rotatably connected to the feed lever 51. The feed lever 51 is recessed along the axial direction with a plurality of annular grooves 511 for the plurality of feed wheels 52 to be inserted; the feed wheels 52 are inserted into the annular grooves 511 and connected to the feed lever 51 through connecting rings 6.

[0026] In this embodiment, the radial thickness of the connecting ring 6 is greater than the radial groove width of the ring groove 511, thereby ensuring that the dial wheel 52 rotates smoothly and does not fall off. That is, this interference fit or small clearance fit allows the connecting ring 6 to be securely embedded in the ring groove 511, thereby restricting the dial wheel 52 to the axial position while allowing it to rotate freely around the lever 51. Furthermore, the connecting ring 6 can be made of wear-resistant engineering plastic or metal.

[0027] In this embodiment, the dial 52 is preferably spherical, cylindrical, or annular in shape, and the material can be further selected from flexible materials such as silicone or polyurethane to protect the surface of the injection molded part.

[0028] The working principle of the material-dispensing assembly 5 is as follows: the telescopic rod 4 extends and retracts at a certain frequency, driving the dispensing rod 51 and the dispensing wheel 52 at its end to insert and retract into the injection molded parts pile. When the dispensing wheel 52 contacts the parts, it will rotate, changing sliding friction into rolling friction, thereby reducing scratches on the surface of the parts, and gently dispersing and turning the injection molded parts, exposing foreign objects hidden at the bottom and inner layers of the parts, making them easier to be blown up by the airflow, effectively improving the removal effect of foreign objects.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, the blower assembly 2 includes a buffer air box 22 and a blower pipe 21 connected to the buffer air box 22; the buffer air box 22 is located on the side wall of the conveying box 1 and is connected to the discharge end 12 of the conveying box 1 through an array of ventilation holes.

[0030] In this embodiment, the blower 21 is connected to an external air source or fan to send airflow into the buffer air box 22. The buffer air box 22 acts as a pressure stabilizing chamber, which can smooth and even out the high-speed turbulent airflow. Then, through the ventilation hole array on the side wall, the airflow is blown towards the conveyed parts in a near-laminar state, thereby avoiding dead airflow and ensuring that foreign objects in various positions can be effectively blown up, thus improving the removal effect of foreign objects.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the suction assembly 3 includes a suction pipe 31 and a filter box connected to the suction pipe 31; the suction pipe 31 is connected to the conveying box 1; the suction pipe 31 is located between a pair of blower assemblies 2; and the material feeding assembly 5 is located at the inlet end of the suction pipe 31.

[0032] In this embodiment, the suction component 3 forms a local negative pressure zone directly above the material feeding component 5. When foreign objects are blown upwards by the blower component 2, the strong suction at the inlet of the suction pipe 31 can quickly capture them and transport them to the filter box, effectively removing the foreign objects. Furthermore, the filter box contains at least one stage of filtration system, such as a pre-filter for intercepting larger debris and a high-efficiency filter cartridge for filtering fine dust. A removable dust collection hopper can be further installed at the bottom of the filter box for easy periodic cleaning. Moreover, the inlet end of the suction pipe 31 can be designed in a trumpet or umbrella shape to expand the suction range and improve collection efficiency.

[0033] The overall workflow of this embodiment is as follows: The injection molded parts flow into the feed end 11 of the inclined vibrating conveyor box 1. When they reach the discharge end 12, the double-sided blower assembly 2 generates a uniform airflow to blow away surface foreign objects. At the same time, the telescopic rod 4 drives the material feeding assembly 5 to reciprocate. The rotating wheel 52 on it flips the pile of parts, exposing deep foreign objects. Then, the suction assembly 3 located directly above forms a negative pressure, which efficiently sucks in the blown-up foreign objects and transports them to the filter box for filtration and collection. Finally, the cleaned parts are continuously discharged into the sorting equipment, realizing online, automatic, and efficient foreign object removal, effectively improving sorting efficiency and part cleanliness.
