Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas recovery of injection molding machines, and particularly relates to a waste gas recovery device for injection molding machines. Background Art

[0002] An injection molding machine is a device used for plastic processing. It heats and compresses plastic raw materials to make them melt and have fluidity, and then injects them into a closed mold under high pressure. After cooling and solidifying, the required plastic products are formed. Injection molding machines are widely used in the manufacture of various plastic products, such as toys, automotive parts, electronic device casings, etc. During the processing of injection molding machines, when heating plastic products to make them melt and have fluidity, some components in the plastic may volatilize to form waste gas. These volatiles may include organic solvents, additives, residual monomers, etc. Inhalation by workers will cause harm to the body. Therefore, when using an injection molding machine, a waste gas recovery device is also used to collect the waste gas to avoid the situation of waste gas flowing in the factory.

[0003] However, there are some problems in the prior art: Currently, after the existing waste gas recovery device has been used for a period of time, in order to avoid excessive impurities on the surface of the activated carbon plate and affect the purification effect, it is necessary to disassemble the activated carbon plate. However, the activated carbon plate inside the existing waste gas recovery device is generally fixed in the waste gas recovery device by bolts and nuts, which is troublesome to disassemble and inconvenient for replacing the activated carbon plate inside it, and there are certain limitations. Therefore, we propose a waste gas recovery device for injection molding machines. Summary of the Utility Model

Specific embodiments

[0023] In order to further understand the content, features and effects of the present utility model, the following embodiments are listed and described in detail in conjunction with the accompanying drawings.

[0024] As Figures 1 to 5 shown, an exhaust gas recovery device for an injection molding machine provided by an embodiment of the present utility model includes: a storage box 1, a vacuum cleaner 2 is detachably installed on the upper surface of the storage box 1, a plurality of groups of activated carbon plates 5 are detachably installed inside the storage box 1, and an exhaust valve 3 is provided on one side of the storage box 1;

[0025] Specifically, as Figure 1 and Figure 2 shown, place the vacuum cleaner 2 on the injection molding machine, then start the vacuum cleaner 2 to absorb the exhaust gas generated by the injection molding machine, inhale the exhaust gas into the storage box 1, filter the exhaust gas through a plurality of groups of activated carbon plates 5, and when discharging, open the exhaust valve 3 to discharge the filtered exhaust gas.

[0026] Furthermore, there are a placing assembly 4 and a baffle assembly 7. The placing assembly 4 is arranged inside the storage box 1, there are multiple groups of baffle assemblies 7, and multiple groups of baffle assemblies 7 are oppositely arranged on both sides of the placing assembly 4. The activated carbon plate 5 is arranged inside the placing assembly 4, and the activated carbon plate 5 is in contact with the baffle assembly 7;

[0027] Specifically, as Figure 2 and Figure 3As shown in the figure, when in use, first push the two sets of opposite baffle components 7 at the two lowermost ends on both sides of the placing component 4 inward to form a support plate inside the placing component 4. Then place a set of activated carbon plates 5 on the upper surfaces of the two baffle components 7. Subsequently, install the upper sets of activated carbon plates 5 in sequence according to the above steps. On the contrary, when disassembling, first take out the two lowermost baffle components 7, take out the lowermost activated carbon plate 5, and then disassemble the upper sets of activated carbon plates 5 in sequence according to the above steps, thereby achieving the convenience of disassembling and assembling the activated carbon plates 5, replacing or cleaning the activated carbon plates 5, and improving the purification effect.

[0028] Furthermore, the placing component 4 includes a placing shell 401 which is hollow inside. Both ends of the upper surface of the placing shell 401 are provided with extension plates 402. Docking grooves 6 are formed on the upper surface of the storage box 1, and the extension plates 402 are clamped with the docking grooves 6.

[0029] Specifically, as Figure 2 and Figure 4 shown, when placing the placing shell 401, align the extension plates 402 at both ends of the upper surface with the docking grooves 6, and make the extension plates 402 stuck in the docking grooves 6 to support the placing shell 401, thereby achieving the effect of facilitating the disassembly and assembly of the placing shell 401.

[0030] Furthermore, multiple groups of notches 403 are formed on both sides of the placing shell 401, and the baffle components 7 are movably installed in the notches 403.

[0031] Specifically, as Figure 3 shown, the multiple groups of baffle components 7 slide inward simultaneously in the notches 403 to form a blocking block inside the placing shell 401. In this way, the activated carbon plates 5 are directly placed in the placing shell 401, and the baffle components 7 support the activated carbon plates 5, thereby completing the installation of the activated carbon plates 5 and achieving the improvement of installation convenience.

[0032] Furthermore, the baffle component 7 includes a partition plate 701. A slider 706 is arranged on the lower surface of the partition plate 701. A sliding groove 404 is formed on the lower surface of the inner wall of the notch 403, and the slider 706 is slidably installed in the sliding groove 404. One end of the slider 706 is provided with a blocking baffle.

[0033] Specifically, as Figure 4 and Figure 5 shown, by sliding the slider 706 in the sliding groove 404, the partition plate 701 slides on one side of the placing shell 401. When the partition plate 701 slides inward, after the baffle at one end of the slider 706 fits with the outer surface of one side of the placing shell 401, the slider 706 cannot slide anymore, thereby achieving the limiting effect.

[0034] Further, installation grooves are formed at both ends on one side of the partition plate 701. A connecting block 704 is slidably installed inside the installation groove. One end of the connecting block 704 is fixedly installed with a limiting rod 705. Limiting holes 405 are formed on both sides of the inner wall of the notch 403. The limiting rod 705 is clamped with the limiting hole 405.

[0035] Specifically, as Figure 4 and Figure 5 shown, slide the connecting block 704 towards one end to insert one end of the limiting rod 705 into the limiting hole 405, so as to limit the partition plate 701, thus achieving the effect of convenient fixation.

[0036] It should be noted that according to the above, when the partition plate 701 slides inwards, the baffle at one end of the slider 706 will fit with the outer surface of one side of the placement shell 401. Therefore, after the partition plate 701 slides inwards, the position of one end of the limiting rod 705 just corresponds to the limiting hole 405, so that the limiting rod 705 is clamped with the limiting hole 405 to limit and fix the partition plate 701.

[0037] Further, the other end of the connecting block 704 is provided with a telescopic rod 702. One end of the telescopic rod 702 is arranged at one end of the inner wall of the installation groove. A plurality of pin holes are formed on one side of the telescopic rod 702. A fixing pin 703 is detachably installed in the pin holes.

[0038] Specifically, as Figure 5 shown, when the connecting block 704 slides, the piston rod end of the telescopic rod 702 will extend. After the sliding adjustment is completed, insert the fixing pin 703 at the position where the pin holes on both sides of the two ends of the telescopic rod 702 coincide, so that the telescopic rod 702 cannot move, thus achieving the effect of limiting the connecting block 704 and making the limiting rod 705 unable to be taken out of the limiting hole 405.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
