Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an injection molding machine with a dust extraction function. Background Technology

[0002] Injection molding machines are core equipment that use heated and melted plastic to inject it into a mold under high pressure, and then cool and solidify it to mass-produce various plastic products from plastic raw materials. They are widely used in many industries such as home appliances, automobiles, medical and packaging. During processing, plastic granules or powders are fed into the barrel from the hopper. The heater outside the barrel heats the material, while the internal screw rotates. Through shearing force, the raw material is melted into a uniform fluid, and finally pushed forward by the internal threaded rod, and extruded into the mold cavity.

[0003] When adding raw materials into the hopper of an injection molding machine, there are usually two feeding methods. When adding small batches of plastic, it is done manually. When adding large batches of plastic, it is conveyed by a vacuum pump and a conveying pipe. However, both of these feeding methods involve directly pouring the material into the hopper. Therefore, the upper surface of the hopper is usually larger than the opening of the conveying pipe or the bag containing the plastic. As a result, dust will be generated at the hopper when adding plastic, and then float in the environment. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides an injection molding machine with a dust collection function, which solves the technical problem in the prior art that dust is easily generated when plastic granules are poured into the feed hopper of the injection molding machine and thus floats in the surrounding environment.

[0005] According to one aspect, at least one embodiment of the present invention provides an injection molding machine with a dust collection function, including an injection molding machine body, on which a feed hopper is installed, and further including a dustproof half-frame, a dust collection and recovery component, and a dust blocking component. Two dustproof half-frames are provided, each mounted on the injection molding machine body via two mounting components. A semi-circular through-groove for discharging material is provided at the top of each dustproof half-frame. The dust collection and recovery component is located on the side of the injection molding machine body for adsorbing dust generated when pouring plastic granules. The dust blocking component is located at the top of the dustproof half-frame for blocking dust from the semi-circular through-groove of the dustproof half-frame.

[0006] Furthermore, the dust collection and recovery assembly includes a support plate, a dust collection box, a negative pressure unit, a suction pipe, and a dust collection component. The support plate is fixedly installed on the side of the injection molding machine body. The dust collection box is detachably installed on the support plate, and a channel for dust to fall is provided at the bottom of the dust collection box. The negative pressure unit is installed on the support plate, and the suction port of the negative pressure unit is connected to the side of the dust collection box. One end of the suction pipe is connected to the top of the dust collection box, and the other end of the suction pipe is connected to the bottom of one of the dustproof half-frames. The dust collection component is disposed inside the dust collection box.

[0007] Furthermore, the dust removal assembly includes a dust baffle plate, a fixing frame, a limiting rod, and a clip. The dust baffle plate is slidably installed through the side of the dust collection box, the fixing frame is fixedly installed on the side of the dust baffle plate, the limiting rod is slidably installed through the side of the fixing frame and the dust baffle plate, and the clip is slidably installed on the side of the dust collection box. The top ends of the fixing frame and the limiting rod are provided with grooves that match the bottom end of the clip.

[0008] Furthermore, the mounting assembly includes mounting blocks, mounting brackets, and mounting bolts. Two mounting blocks are provided, and both mounting blocks are fixedly installed on the top of the injection molding machine body. Two mounting brackets are provided, and the two mounting brackets are respectively installed through the two mounting blocks. The dustproof half-frame is fixedly installed on the side of the two mounting brackets. Threaded holes are provided on the side of both the mounting blocks and the mounting brackets, and the mounting bolts are threaded into the threaded holes.

[0009] Furthermore, the dustproof assembly includes a dustproof disc, a locking block, and a blocking component. The dustproof disc is rotatably mounted on the top of one of the dustproof half-frames via a rotating shaft, and a U-shaped groove is provided at one of the quarter points of the dustproof disc. The locking block is slidably mounted on the top of the other dustproof half-frame, and the locking block is adapted to the U-shaped groove. The blocking component is disposed on the top of one of the dustproof half-frames.

[0010] Furthermore, the blocking assembly includes a placement plate and a blocking block. Two of the placement plates are fixedly installed on the top of the dustproof half-frame, and the blocking block is rotatably installed between the two placement plates via a rotating shaft.

[0011] Furthermore, a dust filter plate is detachably installed inside the dust collection box.

[0012] Furthermore, the area of ​​the dust-blocking disc is greater than the sum of the areas of the two semi-circular through slots.

[0013] The beneficial effects of this utility model are as follows: In this invention, when plastic granules are added into the injection molding machine, two dustproof half-frames are first installed on the injection molding machine body using an installation assembly. At this time, the feed hopper of the injection molding machine body is located inside the two dustproof half-frames, and the two dustproof half-frames are in close contact. If plastic granules need to be conveyed by a conveying pump, the conveying pipe can be installed in the semi-circular through groove of the two dustproof half-frames through a flange. When the plastic granules are conveyed into the injection molding machine body, dust can be blocked in the internal space of the two dustproof half-frames. If a small batch of plastic granules is manually poured, the operator can quickly pour it through the semi-circular through groove and then block the semi-circular through groove with a dust-blocking assembly to prevent dust from escaping. After the material is fed, the dust collection component can absorb the dust in the two dustproof half-frames into the dust collection box, and collect the dust inside after it has accumulated.

[0023] like Figures 1-7 As shown, this invention illustrates an injection molding machine with a dust collection function according to one embodiment of the present invention. The machine includes a machine body 1 with a feed hopper 2 mounted on it. It also includes a dustproof half-frame 3, a dust collection and recovery component, and a dust blocking component. Two dustproof half-frames 3 are provided, each mounted on the machine body 1 via two mounting components. A semi-circular through-slot for material discharge is provided at the top of each dustproof half-frame 3. The dust collection and recovery component is located on the side of the machine body 1 to absorb dust generated during the pouring of plastic granules. The dust blocking component is located at the top of the dustproof half-frame 3 to block dust from the semi-circular through-slot.

[0024] like Figure 2 As shown, when adding plastic granules to the injection molding machine body 1, two dustproof half-frames 3 are first installed at the feed hopper 2 using an installation assembly. The installation assembly includes an installation block 12, an installation bracket 13, and an installation bolt 14. There are two installation blocks 12, both of which are fixedly installed at the top of the injection molding machine body 1. There are two installation brackets 13, which are respectively installed through the two installation blocks 12. The dustproof half-frames 3 are fixedly installed on the sides of the two installation brackets 13. Threaded holes are provided on the sides of both the installation blocks 12 and the installation brackets 13, and the installation bolts 14 are threaded into the threaded holes.

[0025] Specifically, the workers hold two mounting brackets 13 and insert them into the two mounting blocks 12 respectively. Then, they thread the mounting bolts 14 into the threaded holes of the mounting blocks 12 and the mounting brackets 13 to fix them in place. At this time, the sides of the two dustproof half-frames 3 are in contact with each other, and the two semi-circular through slots are combined into a whole circular through slot. The bottom end of the dustproof half-frame 3 is provided with an arc groove that matches the side of the feed hopper 2. When the two dustproof half-frames 3 are in contact, the side of the feed hopper 2 is in contact with the arc groove at the bottom of the dustproof half-frame 3 to prevent dust from escaping.

[0026] When conveying plastic granules by a conveying pump, the conveying pipe is first inserted into the circular through groove. At this time, the diameter of the pipe is consistent with the diameter of the through groove, so as to directly block the through groove. Then, the pipe is connected and fixed with a flange. Then, the conveying pump is started to convey the granules into the feed hopper 2. At this time, the dust generated can be blocked by the two dustproof half frames 3 in the internal space.

[0027] like Figure 3 As shown, when dumping small batches of plastic granules, the worker holds the granule bag and quickly pours the granules into the feed hopper 2 through the circular channel. Then, the channel is blocked by a dust-blocking component. The dust-blocking component includes a dust-blocking disc 15, a locking block 16, and a blocking component. The dust-blocking disc 15 is rotatably installed on the top of one of the dustproof half-frames 3 via a rotating shaft, and a U-shaped groove is provided at one of the quarter points of the dust-blocking disc 15. The locking block 16 is slidably installed on the top of the other dustproof half-frame 3, and the locking block 16 is adapted to the U-shaped groove. The blocking component is set on the top of one of the dustproof half-frames 3. The blocking component includes a placement plate 17 and a blocking block 18. Two placement plates 17 are fixedly installed on the top of the dustproof half-frame 3, and the blocking block 18 is rotatably installed between the two placement plates 17 via a rotating shaft.

[0028] Specifically, after emptying, rotate the dust-blocking disc 15. It should be noted that the rotating shaft is installed at one-quarter of the distance from the dust-blocking disc 15, so that the entire dust-blocking disc 15 can be rotated during rotation. After rotation, slide the sliding block 16 into the U-shaped groove of the dust-blocking disc 15, and then rotate the blocking block 18 to a horizontal position to block the locking block 16. Simultaneously, the dust-blocking disc 15 is limited. Because the area of ​​the dust-blocking disc 15 is greater than the sum of the areas of the two semi-circular through slots, the dust-blocking disc 15 can block the entire through slot, preventing dust from escaping. It should also be noted that the bottom end of the dust-blocking disc 15 is attached to the top end of the dustproof half-frame 3.

[0029] like Figure 4 , Figure 5 and Figure 6As shown, after the dust is added, it is trapped inside the dust-blocking half-frame, allowing the dust to be absorbed by the dust collection and recovery assembly. This assembly includes a support plate 4, a dust collection box 5, a negative pressure unit 6, a suction pipe 7, and a dust collection component. The support plate 4 is fixedly installed on the side of the injection molding machine body 1. The dust collection box 5 is detachably installed on the support plate 4, and a channel for dust to fall is provided at the bottom of the dust collection box 5. The negative pressure unit 6 is installed on the support plate 4, and its suction port is connected to the side of the dust collection box 5. One end of the suction pipe 7 is connected to the... At the top of the dust collection box 5, and with the other end of the suction pipe 7 connected to the bottom of one of the dustproof half-frames 3, the dust lowering assembly is installed inside the dust collection box 5. The dust lowering assembly includes a dust baffle 8, a fixing frame 9, a limiting rod 10, and a card holder 11. The dust baffle 8 is slidably installed through the side of the dust collection box 5, the fixing frame 9 is fixedly installed on the side of the dust baffle 8, the limiting rod 10 is slidably installed through the side of the fixing frame 9 and the side of the dust baffle 8, and the card holder 11 is slidably installed on the side of the dust collection box 5. The top of the fixing frame 9 and the limiting rod 10 are provided with grooves that are adapted to the bottom of the card holder 11.

[0030] Specifically, after the plastic granules enter the feed hopper 2, the operator starts the negative pressure machine 6. The negative pressure machine 6 extracts the air from the dust collection box 5, thereby creating a pressure difference. The dust then enters the dust collection box 5 through the suction pipe 7. Because the dust collection box 5 is equipped with a dust filter plate 19 that can be detached by bolts or clips, the dust can be blocked inside the dust collection box 5, preventing the dust from being absorbed by the negative pressure machine 6 and thus causing damage. After the dust is absorbed, once the dust has fallen to the top of the dust baffle plate 8 inside the dust collection box 5, the operator can take a collection bag, place it at the bottom of the dust baffle plate 8, and then move the bracket 11 upward to separate it from the fixing bracket 9 and the limiting rod 10. Then, pull the limiting rod 10 to separate it from the side of the dust baffle plate 8 and slowly pull the dust baffle plate 8. At this time, the dust particles inside can fall into the collection bag below for collection.

[0031] Working principle: When feeding the injection molding machine body 1, the operator first holds two mounting brackets 13 and inserts them into the two mounting blocks 12 respectively. Then, the mounting bolts 14 are threaded into the threaded holes of the mounting blocks 12 and the mounting brackets 13 to fix them. At this time, the sides of the two dustproof half-frames 3 are in contact. Then, the plastic granules are added into the feed hopper 2. After the hopper is emptying, the dustproof disc 15 is rotated to cover the entire through groove. After the rotation is completed, the sliding block 16 is slid into the U-shaped groove of the dustproof disc 15. Then, the blocking block 18 is rotated to a horizontal position to block the blocking block 16. Simultaneously, the dustproof disc 15 is limited to prevent dust from escaping.

[0032] When plastic granules are added into the feed hopper 2, the operator starts the negative pressure machine 6. The negative pressure machine 6 extracts the air from the dust collection box 5, thereby creating a pressure difference. The dust enters the dust collection box 5 through the suction pipe 7. After the dust is absorbed, once the dust has fallen to the top of the dust baffle 8 in the dust collection box 5, the operator can take the collection bag, place it at the bottom of the dust baffle 8, and then move the bracket 11 upward to separate it from the fixing bracket 9 and the limiting rod 10. Then, pull the limiting rod 10 to separate it from the side of the dust baffle 8 and slowly pull the dust baffle 8. At this time, the dust particles inside can fall into the collection bag below for collection.

[0033] like Figure 7 As shown, the injection molding machine body 1 is then started. The plastic granules are heated and melted inside the injection molding machine body 1, and then the internal screw rotates and moves forward to extrude the molten plastic granules through the extrusion mold at the side end.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
