[0030] Reference Figure 1-8 This utility model discloses a PET plastic packaging box injection molding device, which includes a vertical injection molding machine 1, a worktable 2 on the vertical injection molding machine 1, a lower mold 3 fixedly connected to the worktable 2, an upper mold 4 and a feeding bin 5 respectively on the vertical injection molding machine 1, a filter box 6 fixedly connected to the vertical injection molding machine 1, a support block 7 fixedly connected to the front surface of the filter box 6, a fan 8 fixedly connected to the support block 7, an air outlet pipe 9 fixedly connected to the output end of the fan 8, a connecting pipe 10 fixedly connected to the input end of the fan 8, an air inlet pipe 11 fixedly connected to the inner surface of the filter box 6, a suction head 12 fixedly connected to the end of the air inlet pipe 11 away from the filter box 6, a baffle 13 movably connected to the filter box 6, activated carbon filter cotton 14 movably connected to the inner surface of the filter box 6, and a first sealing ring 15 fixedly connected to the inner surface of the filter box 6. The inner surface of the baffle 13 is fixedly connected to the second sealing ring 16, the outer surface of the connecting pipe 10 is fixedly connected to the filter box 6, the fan 8 is electrically connected to the external power supply, the right surface of the second sealing ring 16 is in contact with the first sealing ring 15, the rear surface of the baffle 13 is in contact with the activated carbon filter cotton 14, and the left surface of the baffle 13 is fixedly connected to the handle 17. Under the action of the first sealing ring 15 and the second sealing ring 16, the sealing between the filter box 6 and the baffle 13 can be ensured, so that the gas in the external environment can smoothly enter the filter box 6, and it can also prevent unfiltered air from leaking into the external environment. At the same time, under the action of the handle 17, the baffle 13 can be easily operated through a force point. The vertical injection molding machine 1 is an existing mature equipment, and the specific structure and working principle will not be described in detail here.

[0031] Multiple connecting blocks 18 are fixedly connected to the baffle 13. Insert blocks 19 are fixedly connected to the side surface of the connecting blocks 18. Multiple positioning blocks 20 are fixedly connected to the filter box 6. The outer surface of the insert block 19 is movably connected to the positioning block 20. The inner surface of the insert block 19 is threadedly connected to the bolt 21. The positioning block 20 has a positioning groove 22. The outer surface of the insert block 19 is movably connected to the positioning groove 22. The insert block 19 has a first connecting groove 23. The outer surface of the bolt 21 is movably connected to the first connecting groove 23. The positioning block 20 has a second connecting groove 24. The outer surface of the bolt 21 is threadedly connected to the second connecting groove 24. There are four bolts 21 distributed in a rectangular array.

[0032] Working principle: During the injection molding process of the entire device, the fan 8 on the support block 7 is started, which causes the connecting pipe 10 to generate suction. At this time, under the action of the connecting pipe 10, the air in the filter box 6 and the baffle 13 can enter the fan 8 through the connecting pipe 10, and then be discharged to the outside environment through the air outlet pipe 9 on the fan 8. With the continuous operation of the fan 8, the air in the filter box 6 and the baffle 13 will gradually decrease and generate negative pressure, which will allow the air in the outside environment to enter the filter box 6 and the baffle 13 through the suction head 12 and the air inlet pipe 11. When air from the outside environment enters the filter box 6 and baffle 13 and comes into contact with the activated carbon filter cotton 14, the activated carbon filter cotton 14 can adsorb and filter the odor in the air. Then, the filtered air enters the fan 8 through the connecting pipe 10, and finally is discharged to the outside environment through the exhaust pipe 9. This achieves the filtration of the gas generated during the overall processing of the device, reducing the impact on the workshop environment. Furthermore, when the activated carbon filter cotton 14 becomes saturated after a period of use, the bolt 21 can be removed from the insert block 19 and positioning block 20 using a wrench or other tools. After unscrewing, the fixing between the filter box 6 and the baffle 13 can be released. Then, pull the handle 17 to remove the baffle 13 and its structure from the filter box 6. Once the baffle 13 is removed, the activated carbon filter cotton 14 can be taken out of the filter box 6. Then, a new activated carbon filter cotton 14 of the same type can be placed into the filter box 6. Then, insert the insert block 19 on the baffle 13 into the positioning groove 22 on the positioning block 20 using the handle 17. When the baffle 13 contacts the filter box 6 and the activated carbon filter cotton 14, the first connecting groove 23 and the second connecting groove 23 can be connected. The corresponding slots 24 are then aligned, and the bolts 21 are screwed back into the first connecting slot 23 and the second connecting slot 24, thereby fixing the insert block 19 and the positioning block 20, and thus fixing the filter box 6 and the baffle 13. At this time, under the action of the baffle 13, the activated carbon filter cotton 14 is fixed, and the replacement of the activated carbon filter cotton 14 is completed. Under the action of the first sealing ring 15 and the second sealing ring 16, the sealing between the filter box 6 and the baffle 13 can be improved, preventing unfiltered gas from leaking into the external environment from the connection between the filter box 6 and the baffle 13.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
