[0024] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation mode, structure, features and their effects of the present invention as follows.

[0025] As Figures 1-6 shown, a dust collection device for the injection molding production process includes an air pump, a filter tank 21, an air duct, a connection structure and a corrugated structure 7. The air pump is installed on the filter tank 21, and the output end of the air pump extends into the filter tank 21. The air duct includes a communicating horizontal channel 4 and a vertical channel 3. The upper end of the air pump is connected to the vertical channel 3. A round hole 401 is opened at the lower end of the horizontal channel 4. The connection structure is installed in the round hole 401. The corrugated structure 7 is installed at the lower end of the connection structure. The corrugated structure 7 can be twisted to any angle to adapt to the layout and placement angle of the injection molding equipment. Channels are provided in the middle of the connection structure and the corrugated structure 7. Under the action of the air pump, the injection molding dust enters the horizontal channel 4 and the vertical channel 3 through the channels in the middle of the corrugated structure 7 and the connection structure, and finally enters the filter tank 21, and the dust is adsorbed by the liquid in the filter tank 21. If the purification of the injection molding tail gas is to be achieved, existing technologies such as acid-base liquid and liquid carbon can be used for treatment, so that the harmful substances in the injection molding tail gas are adsorbed or neutralized. An exhaust pipe 101 is provided at the upper end of the filter tank 21 to discharge the gas filtered by the filter tank 21 from the side.

[0026] In the above embodiments, a guiding groove 403 is provided in the round hole 401, and a guide rail 502 is provided on the side of the connecting structure. The guide rail 502 is slidably connected to the guiding groove 403 to prevent the connecting structure from rotating randomly. The force on the connecting structure is kept stable by a plurality of guide rails 502 and guiding grooves 403. When the corrugated structure 7 is twisted to adjust its position and angle, the connection between the connecting structure and the transverse channel 4 is tight without air leakage, ensuring the airtightness of the entire section of the air duct and improving the dust suction effect. A fixing piece 9 is provided at the lower end of the transverse channel 4. The fixing piece 9 is located on the side of the guiding groove 403. A through hole 901 is provided on the fixing piece 9, and a threaded hole is provided on the guide rail 502. The through hole 901 and the threaded hole can be connected by a screw. After the connecting structure is upwardly inserted into the round hole 401, the connecting structure and the transverse channel 4 are connected and fixed by a screw, ensuring the stability of the connection and preventing the connecting structure from disengaging from the assembly position of the transverse channel 4, which may cause air leakage and abnormal use of the transverse channel 4.

[0027] In the above embodiments, the connecting structure includes a ventilation member 5 and an adapter member 6. The ventilation member 5 and the adapter member 6 are threadedly connected. The guide rail 502 is located on the side of the ventilation member 5. Channels are provided in the middle of both the ventilation member 5 and the adapter member 6. First, the ventilation member 5 is inserted into the round hole 401 and fixed by a screw, and then the adapter member 6 connected to the corrugated structure 7 is inserted into the lower end of the ventilation member 5. Compared with inserting the entire connecting structure into the transverse channel 4, the operation is more convenient and faster. The ventilation member 5 includes an adapter ring 503 and a baffle 501. The adapter ring 503 is provided with internal threads. The guide rail 502 is located on the side of the adapter ring 503. The baffle 501 is installed at the upper end of the guide rail 502. There is a gap between the baffle 501 and the adapter ring 503. The baffle 501 passes over the round hole 401 of the transverse channel 4, that is, this branch is connected, and dust is sucked from the injection molding equipment at the lower end of this branch. A round groove 402 is provided at the upper end of the round hole 401. The baffle 501 is circular and can be inserted into the round groove 402. When the injection molding equipment stops running, the screw on the guide rail 502 can be removed, so that the baffle 501 of the ventilation member 5 is inserted into the round groove 402 to close this branch, improving the dust suction effect of other running branches. The adapter member 6 is a ring structure, with external threads provided at the upper part for connecting the ventilation member 5, a retaining ring 601 provided in the middle to limit the assembly depth of the adapter member 6, and an anti-slip structure 602 provided at the lower part for assembling the corrugated structure 7. The corrugated structure 7 can be sleeved outside the anti-slip structure 602 and quickly fixed by a screw or a wire, thus achieving a good stable connection relationship. The middle part of the corrugated structure 7 is a corrugated metal hose 701. After the position and angle are adjusted by twisting, it can maintain its state by itself, thus maintaining a stable dust suction effect. A dust collection hood 8 is provided at the lower end of the corrugated structure 7. The dust collection hood 8 is communicated with the corrugated structure 7. The dust collection hood 8 can increase the dust suction range. A handle 801 is provided on the side of the dust collection hood 8, which is convenient for pulling the dust collection hood 8 and aligning it with the injection molding equipment.

[0028] Description of the working mode of the present utility model:

[0029] Arrange the filter tank 21 of the device outside the workshop. The vertical channel 3 and the horizontal channel 4 of the air duct pass through the reserved ventilation opening of the workshop. The horizontal channel 4 is vertically and horizontally distributed and hoisted above the injection molding equipment in the workshop. The air duct horizontal channel 4 above the pedestrian passage or freight passage can use an air duct without round holes 401, or continue to use an air duct with round holes 401. The baffle 501 at the upper end of the ventilation part 5 is embedded into the round hole 401 to close the round hole 401 of this section of the air duct, so as to avoid inhaling the workshop air, wasting dust collection resources and reducing the dust collection efficiency. Install the ventilation part 5, the adapter 6 and the corrugated structure 7 on the horizontal channel 4 above the injection molding equipment. First, connect and fix the ventilation part 5 through the screw hole 504 of the guide rail 502 and the through hole 901 of the fixing piece 9 with screws. Then, fix the anti-slip structure 602 at the lower end of the adapter 6 and the corrugated structure 7 with screws, steel wires or welding. Subsequently, screw the upper end of the adapter 6 into the lower end of the ventilation part 5 to complete the installation of the device; by using this method, first connect the adapter 6 and the corrugated structure 7, assemble the overall structure with larger weight and space first, and then connect it to the lower end of the ventilation part 5 by an assembly method, which is convenient and fast to operate, and takes into account labor saving and safety. After the installation of the device is completed, adjust the position and angle of the corrugated structure 7 through the handle 801 to align it with the injection molding equipment, and start the air pump to carry out dust collection operations. When the injection molding equipment stops due to maintenance or off-peak production, the screws in the fixing piece 9 and the guide rail 502 can be removed, and the overall structure composed of the ventilation part 5, the adapter 6 and the corrugated structure 7 sinks. The baffle 501 at the upper end of the ventilation part 5 is embedded into the round groove 402 of the air duct horizontal channel 4 to close this section of the branch, avoiding wasting dust collection resources and improving the dust collection effect of other branches. By using this device to collect dust at a position close to the injection molding equipment, the injection molding dust is collected from the source, avoiding the injection molding dust from gathering in the workshop at a high concentration and affecting the health of workers.

[0030] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
