Description

Technical Field

[0001] This application relates to the field of plastic box processing technology, and more specifically, to a chip removal device for the production of wear-resistant plastic boxes. Background Technology

[0002] Plastic boxes are box-shaped containers made of plastic as raw material through processes such as injection molding, blow molding, and vacuum forming. During the processing (such as injection molding, cutting, grinding, and assembly), waste chips, dust, and other impurities are easily left on the surface of plastic boxes, so a chip removal device is needed to remove chips from the plastic boxes.

[0003] Patent CN211538878U discloses a shaving removal device for plastic boxes. This patent uses a combination of a shaving hood, a shaving port, an air supply pipe, and a blower to remove waste and dust from plastic boxes, thereby ensuring the quality and subsequent use of the plastic boxes.

[0004] Although the patent can remove shavings from plastic boxes, it is difficult to remove the sticky debris from the grooves and gaps of the box because the angle of the air guide grille is fixed. At the same time, the front of the shaving cover is not protected, and the airflow generated by the blower can easily blow the debris from the opening into the workshop, causing environmental pollution. Utility Model Content

[0005] To address the aforementioned problems, this application provides a chip removal device for the production of wear-resistant plastic boxes.

[0006] The chip removal device for the production of wear-resistant plastic boxes provided in this application adopts the following technical solution:

[0007] A chip removal device for the production of wear-resistant plastic boxes includes a chip removal hood, a blower hood on the top of the chip removal hood, and a feeding hopper connected to the bottom of the chip removal hood.

[0008] The bottom of the hopper is provided with a discharge port, and a second filter plate is provided on one side of the hopper. One end of the hopper is connected to a negative pressure pipe, which is located on one side of the second filter plate.

[0009] The chip removal hood has an openable and closable protective door on one side to prevent processing chips from spilling out.

[0010] The above technical solution allows the openable and closable protective door to close during chip removal, forming a relatively enclosed space that blocks airflow from blowing debris into the workshop from the opening. This solves the problem of debris overflow caused by the lack of protection on the front side of the chip shield, and helps maintain a clean workshop environment.

[0011] Furthermore, a negative pressure fan is installed on one side of the chip removal hood, and the negative pressure fan is connected to a negative pressure pipe.

[0012] Furthermore, a connecting pipe is connected to the top of the blower cover, and a blower is provided on one side of the dandruff removal cover, with the connecting pipe connected to the blower.

[0013] Through the above technical solution, the blower blows air into the chip removal hood through the blower hood. Combined with the suction formed by the negative pressure pipe, the airflow can more comprehensively act on all parts of the plastic box. Compared with the fixed-angle air guide grille, it reduces the dead angles in chip removal caused by the single direction of airflow and improves the thoroughness of chip removal.

[0014] Furthermore, a filter box is provided at one end of the connecting pipe.

[0015] Furthermore, a support frame is provided at the bottom of the ash removal hood, and a detachable first filter plate is provided above the support frame.

[0016] Furthermore, a detachable storage box is provided below the hopper, and a flexible sealing structure is provided on the top of the storage box. The upper end of the flexible sealing structure is in sealed contact with the bottom of the chip removal hood.

[0017] Furthermore, one end of the storage box has a through hole, and one end of the negative pressure pipe extends through the through hole to the outside of the flexible sealing structure.

[0018] Furthermore, handles are fixedly connected to one end of both the protective door and the storage box.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) This utility model blows air into the chip removal hood through the blower and the suction formed by the negative pressure pipe. The airflow can act more comprehensively on all parts of the plastic box. Compared with the fixed angle of the air guide grille, it reduces the dead angle of chip removal caused by the single direction of airflow and improves the thoroughness of chip removal.

[0021] (2) This utility model can effectively avoid environmental pollution caused by the overflow of debris during the chip removal process. The openable and closable protective door can be closed during chip removal to form a relatively closed space, blocking the airflow from blowing debris from the opening into the workshop. This solves the problem of debris overflow caused by the lack of protection on the front side of the chip shield, which is conducive to maintaining the cleanliness of the workshop environment.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-5 A chip removal device for the production of wear-resistant plastic boxes includes a chip removal hood 1, a blower hood 5 on the top of the chip removal hood 1, and a feeding hopper 13 connected to the bottom of the chip removal hood 1.

[0030] The bottom of the hopper 13 is provided with a discharge port 14, and a second filter plate 15 is provided on one side of the hopper 13. One end of the hopper 13 is connected to a negative pressure pipe 11, which is located on one side of the second filter plate 15.

[0031] The chip removal hood 1 has an openable and closable protective door 2 on one side to prevent processing chips from spilling out.

[0032] First, open the protective door 2 using the handle 3 on the protective door 2, and place the wear-resistant plastic box to be removed into the chip removal hood 1; close the protective door 2 to prevent processing chips from overflowing, and then the relevant blowing equipment blows air into the chip removal hood 1 through the blowing hood 5 on the top of the chip removal hood 1. The airflow acts on the plastic box and blows off the chips on its surface; the blown-off chips move downward under the action of gravity and airflow and enter the feed hopper 13 connected to the bottom of the chip removal hood 1; the negative pressure pipe 11 on one side of the feed hopper 13 forms a suction force under the action of negative pressure, which helps the chips move in the hopper, while the second filter plate 15 can prevent chips from entering the negative pressure pipe 11 and causing blockage. Finally, the chips are discharged and collected through the discharge port 14 at the bottom of the feed hopper 13.

[0033] When the plastic box is placed in the lint remover 1, the plastic box can be arranged in an orderly manner using an external rack, making the lint removal process more even.

[0034] Reference Figures 1-2 A negative pressure fan 12 is provided on one side of the ash removal hood 1. The negative pressure fan 12 is connected to the negative pressure pipe 11. A connecting pipe 6 is provided at the top of the blower hood 5. A blower 8 is provided on one side of the ash removal hood 1. The connecting pipe 6 is connected to the blower 8. A filter box 7 is provided at one end of the connecting pipe 6.

[0035] Start the blower 8 and negative pressure fan 12. The airflow generated by the blower 8 enters the filter box 7 through the connecting pipe 6 to filter and remove impurities from the air. The filtered clean airflow is then delivered to the blower hood 5 through the connecting pipe 6 and blown out of the blower hood 1 into the plastic box inside the dust removal hood, blowing off the debris on the surface of the plastic box.

[0036] Reference Figures 4-5 The inner bottom of the chip removal hood 1 is provided with a support frame 16, and a detachable first filter plate 4 is provided above the support frame 16. A detachable storage box 9 is provided below the hopper 13. A flexible sealing structure 10 is provided on the top of the storage box 9. The upper end of the flexible sealing structure 10 is in sealed contact with the bottom of the chip removal hood 1. A through hole 17 is provided at one end of the storage box 9. One end of the negative pressure pipe 11 extends through the through hole 17 to the outside of the flexible sealing structure 10.

[0037] After a period of use, small debris may remain in the holes of the first filter plate 4. At this time, the operator can remove the first filter plate 4. Since the first filter plate 4 is placed in the support frame 16, it can be easily disassembled for cleaning and maintenance.

[0038] When the storage box 9 has collected a large amount of debris, it can be taken out to clean the debris inside. First, disconnect the negative pressure pipe 11 from the port of the negative pressure fan 12, and then push the flexible sealing structure 10 downward. At this time, pull the negative pressure pipe 11 out from the inside of the through hole 17 so that the negative pressure pipe 11 does not contact the flexible sealing structure 10. Then take out the storage box 9 for cleaning.

[0039] During installation, align the storage box 9 with the installation position at the bottom of the hopper 13, push the flexible sealing structure 10 upwards, and when it is halfway pushed, insert the negative pressure pipe 11 through the outside of the through hole 17 of the storage box 9, so that one end of the negative pressure pipe 11 extends to the outside of the flexible sealing structure 10. Connect one end of the negative pressure pipe 11 to the negative pressure fan 12. After the connection is completed, push the flexible sealing structure 10 again so that its upper end is in tight sealing contact with the bottom of the chip removal hood 1 to ensure the sealing of the negative pressure environment.

[0040] Reference Figures 1-3 The protective door 2 and the storage box 9 are both fixedly connected to one end with a handle 3.

[0041] Working Principle: First, the plastic boxes are placed orderly on the first filter plate 4 above the bottom support frame 16 inside the chip removal hood 1 using an external placement rack. The closable protective door 2 is closed to prevent debris from overflowing. The blower 8 and negative pressure fan 12 are started. The airflow generated by the blower 8 enters the filter box 7 through the connecting pipe 6, filtering out impurities in the air. The clean airflow is then delivered to the blower hood 5 through the connecting pipe 6, and blown out of the blower hood 1 onto the plastic boxes inside the chip removal hood 1, blowing off the debris on the surface of the plastic boxes. The blown-off debris moves downward under the combined action of gravity, the airflow generated by the blower 8, and the negative pressure generated by the negative pressure fan 12, passing through the first filter plate 4 and entering the discharge hopper 13 connected to the bottom of the chip removal hood 1. The negative pressure pipe 11 on one side of the discharge hopper 13 forms a suction force under the action of the negative pressure fan 12, assisting the debris to move in the hopper, while the second filter plate 15 prevents debris from entering the negative pressure pipe 11 and causing blockage. Finally, the debris falls through the discharge port 14 at the bottom of the hopper 13 into the storage box 9 below. The flexible sealing structure 10 at the top of the storage box 9 is in sealed contact with the bottom of the chip removal hood 1, ensuring the stability of the negative pressure environment.

[0042] After the first filter plate 4 has been used for a period of time, it may be removed from the support frame 16 for cleaning and maintenance because small debris may remain in the pores.

[0043] When the storage box 9 collects a large amount of debris, first disconnect the negative pressure pipe 11 from the port of the negative pressure fan 12, then push the flexible sealing structure 10 downwards, and then pull the negative pressure pipe 11 out from the inside of the through hole 17 so that the negative pressure pipe 11 does not contact the flexible sealing structure 10, and the storage box 9 can be taken out for cleaning; after cleaning, place the storage box 9 under the discharge hopper 13, pull the flexible sealing structure 10, and when it is pulled halfway, insert the negative pressure pipe 11 from the outside of the through hole 17 so that one end extends to the outside of the flexible sealing structure 10, align the storage box 9 with the bottom installation position of the discharge hopper 13, push the flexible sealing structure 10 upwards so that it is in close contact with the bottom of the chip removal hood 1, and finally reconnect the negative pressure pipe 11 to the port of the negative pressure fan 12 to complete the reset.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
