Description

Technical Field

[0001] This utility model relates to the fields of plastic processing and environmental protection technology, and in particular to a feeding and dust removal device for a two-stage plastic granulation unit. Background Technology

[0002] A two-stage plastic granulator is a commonly used piece of equipment in the plastics processing industry. It is primarily used to process various plastic raw materials into granular products for subsequent use in the production of plastic products. During operation, the two-stage plastic granulator generates a large amount of dust. A dust collector draws in dust-laden air through an intake port, filters it, and then discharges clean air into the workshop, effectively reducing dust concentration and ensuring the working environment meets occupational health and safety standards. This protects the health of operators and reduces the harm caused by dust to the respiratory system. The filter screen intercepts larger particulate impurities in the air entering the dust collector, such as plastic debris, fibers, and dust clumps. If these large particles enter the dust collector directly, dust will accumulate on the filter screen after prolonged use. If not cleaned promptly, the dust will gradually accumulate on the filter screen, clogging the pores and increasing air resistance. This reduces the amount of air entering the dust collector, making it unable to effectively remove dust from the workshop and thus reducing the dust collector's ability to purify the working environment.

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1

[0032] Reference Figures 1-8 This is the first embodiment of the present utility model. This embodiment provides a feeding dust removal device for a two-stage plastic granulator. The bearing dust protection device of the power tool includes a main component 100 and a dust removal component 200. The two work together to clean the dust accumulated on the filter screen when the dust collector is started and to facilitate the collection of dust after cleaning.

[0033] Specifically, the main component 100 includes a dust collector 101, which is connected to an air inlet pipe 102 and an air outlet pipe 103 at the other end.

[0034] A filter screen is usually installed on the air inlet duct 102.

[0035] The dust collector 101 filters and purifies dust-laden gas, separating dust particles from the gas so that the discharged gas meets environmental emission standards, thereby effectively improving air quality. The primary function of the inlet pipe 102 is to guide the dust-laden gas into the dust collector 101. After the dust-laden gas enters the dust collector 101 through the inlet pipe 102, it is filtered by the filter cartridge inside the dust collector 101. The dust is trapped on the outer surface of the filter cartridge, and the purified gas enters the clean air chamber and is then discharged from the dust collector 101 through the outlet pipe 103, so that the purified air returns to the atmosphere or enters the subsequent ventilation system.

[0036] Specifically, the dust removal component 200 is located at one end of the air inlet pipe 102 and includes a dust removal component 201, including a cleaning brush 201a. A connecting rod 201b is fixed to one end of the cleaning brush 201a, and a driving rod 201c is fixed to one end of the connecting rod 201b. A moving rod 201d is hinged to one end of the driving rod 201c. A collection frame 201e is provided on one side of the moving rod 201d. A door 201f is provided on the inner wall of the collection frame 201e, and a door hinge 201g is inserted into the inner wall of the door 201f.

[0037] A filter screen is also provided on the collection box 201e, so that the dust can be caught in the collection box when the door 201f needs to be opened to collect dust.

[0038] The connecting rod 201b supports the cleaning brush 201a. Moving the movable rod 201d moves the drive rod 201c, which in turn moves the connecting rod 201b, which in turn moves the cleaning brush 201a. As the cleaning brush 201a moves, it moves across the filter screen, cleaning the dust on the screen. The movement of the cleaning brush 201a carries the dust through the bottom of the filter screen into the inner wall of the collection frame 201e, allowing the dust to fall onto the door 201f. At this point, the airflow from the dust collector 101 causes the door hinge 201g to rotate, opening the door 201f. The collection box is then placed under the door 201f to collect the dust, thus completing the cleaning of the filter screen.

[0039] By moving the movable rod 201d, the movement of the movable rod 201d drives the drive rod 201c to move, which in turn drives the connecting rod 201b to move. The connecting rod 201b then drives the cleaning brush 201a to move. As the cleaning brush 201a moves, it moves across the filter screen to clean the dust on the screen. When the cleaning brush 201a moves, it carries the dust into the inner wall of the collection frame 201e, allowing the dust to fall onto the door 201f for collection. At this time, the airflow from the dust collector 101 drives the door hinge 201g to rotate. The rotation of the door hinge 201g causes the door 201f to open and close. When the door 201f is open, the dust can be extracted, thus completing the cleaning of the dust on the filter screen.

[0040] Example 2

[0041] Reference Figures 1-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0042] Specifically, the dust removal assembly 200 also includes a driving component 202, which includes a fixed shaft 202a that is fixed to the inner wall of the moving rod 201d and a fixed plate 202b is fixed to one end of the fixed shaft 202a.

[0043] The fixed shaft 202a and the moving rod 201d are movably connected. By rotating the fixed plate 202b, the fixed plate 202b rotates, which in turn drives the fixed shaft 202a to rotate. The movement of the fixed shaft 202a can then drive the moving rod 201d to move.

[0044] Specifically, a worm gear 202c is sleeved on the outer side of the fixing plate 202b, and a fixing rod 202d is inserted into the inner wall of the worm gear 202c. The other end of the fixing rod 202d is fixed to one end of the air inlet pipe 102.

[0045] The fixed rod 202d is used to support the worm gear 202c and is movably connected to it. By rotating the worm gear 202c, the rotation of the worm gear 202c can drive the fixed plate 202b to rotate.

[0046] Specifically, a support frame 202e is fitted on the outside of the fixing rod 202d, and two support bars 202f are fixed to the other end of the support frame 202e. The other end of the support bar 202f is fixed to one end of the air inlet pipe 102.

[0047] The support frame 202e is used to protect the worm gear 202c. The connecting rod 201b is also inserted into the inner wall of the support frame 202e for movable connection. The support bar 202f is used to support the support frame 202e.

[0048] Specifically, a worm 202g is provided at one end of the worm gear 202c, and a connecting strip 202h is inserted into the inner wall of the worm 202g. The connecting strip 202h is inserted into the inner wall of the support frame 202e and rotates.

[0049] The connecting bar 202h is used to support the worm 202g. By rotating the connecting bar 202h, the worm 202g will rotate, and the worm 202g will mesh with the worm wheel 202c to make it rotate.

[0050] Specifically, a motor 202i is installed at one end of the connecting strip 202h.

[0051] The motor 202i is existing technology. The motor 202i can drive the connecting bar 202h to rotate. A support frame is fitted on the outside of the motor 202i to support the motor 202i. The other end of the support frame is fixed to the top of the collection frame 201e.

[0052] When it is necessary to clean the dust accumulated on the filter screen, the motor 202i is started. The power of the motor 202i drives the connecting bar 202h to rotate. When the connecting bar 202h rotates, it rotates on the inner wall of the support frame 202e. The connecting bar 202h drives the worm gear 202g to rotate until it meshes with the worm wheel 202c, causing the worm wheel 202c to rotate. The rotation of the worm wheel 202c drives the fixed plate 202b to rotate. The rotation of the fixed plate 202b drives the fixed shaft 202a to rotate. The movement of the fixed shaft 202a drives the moving rod 201d to move. The movement of the moving rod 201d drives the drive rod 201c to move. The movement of the drive rod 201c drives the connecting rod 201b to move. The connecting rod 201b drives the cleaning brush 201a to move. When the cleaning brush 201a moves, it moves on the filter screen to clean the dust on the filter screen.

[0053] Example 3

[0054] Reference Figures 7-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0055] Specifically, the dust removal assembly 200 also includes a collection component 203, which includes a guide plate 203a fixed inside the collection frame 201e. One end of the collection frame 201e is connected to a guide tube 203b, which is inserted into the inner wall of the air inlet pipe 102.

[0056] When the cleaning brush 201a moves, it will bring dust into the inner wall of the collection frame 201e. Then, when the dust collector 101 is started, the dust will be blown onto the door body 201f by the air force of the dust collector 101 for concentration. After the dust collector 101 is turned on, some of the air force will be blown into the inner wall of the collection frame 201e through the guide tube 203b, and then the dust will be concentrated onto the door body 201f by the guide plate 203a on the inner wall of the collection frame 201e.

[0057] Specifically, a drive plate 203c is provided at one end of the door hinge 201g, and a connecting rod 203d is also fixed on the surface of the door hinge 201g.

[0058] A baffle is provided on one side of the connecting rod 203d, and the other end of the baffle is fixed to the inner wall of the air inlet pipe 102 to protect the connecting rod 203d and prevent it from rotating continuously and entering the air inlet pipe 102 by air force. The air force can make the drive plate 203c rotate, and the rotation of the drive plate 203c drives the door hinge 201g to rotate. The rotation of the door hinge 201g can drive the door 201f to open and discharge the collected dust. When the door hinge 201g rotates, it will also rotate on the inner wall of the air inlet pipe 102.

[0059] Specifically, a protective disc 203e is fixed to the other end of the door hinge 201g.

[0060] The protective disc 203e is used to protect the door hinge 201g and prevent it from falling off when rotating.

[0061] Specifically, a torsion spring 203f is also fitted on the outside of the door hinge 201g. One end of the torsion spring 203f is fixed to one end of the collection frame 201e, and the other end is fixed to one end of the protective plate 203e.

[0062] By moving the drive plate 203c, the drive plate 203c drives the door hinge 201g to rotate. The door hinge 201g drives the protective disc 203e to rotate. The rotation of the protective disc 203e applies pressure to the torsion spring 203f. At this time, the door 201f opens and discharges the collected dust. After the dust is discharged, when the dust collector 101 has finished its work, there will be no wind blowing on the drive plate 203c. At this time, the force of the torsion spring 203f's rebound can drive the door 201f to close for the next use.

[0063] In use, when it is necessary to clean the dust accumulated on the filter screen of the air inlet duct 102, the motor 202i is started. The power of the motor 202i drives the connecting bar 202h to rotate. The connecting bar 202h drives the worm gear 202g to rotate until it meshes with the worm wheel 202c, causing the worm wheel 202c to rotate. The rotation of the worm wheel 202c drives the fixed plate 202b to rotate. The rotation of the fixed plate 202b drives the fixed shaft 202a to rotate. The movement of the fixed shaft 202a can drive... The moving rod 201d moves, which in turn moves the drive rod 201c. The drive rod 201c then moves the connecting rod 201b, which in turn moves the cleaning brush 201a. As the cleaning brush 201a moves, it moves across the filter screen, cleaning the dust on the screen. The movement of the cleaning brush 201a carries the dust into the inner wall of the collection frame 201e. Then, when the dust collector 101 is started, the dust is collected and discharged. The airflow from unit 1 blows dust onto the door body 201f for collection. When the dust collector 101 is turned on, some of the airflow is blown into the inner wall of the collection frame 201e through the guide pipe 203b. Then, guided by the guide plate 203a on the inner wall of the collection frame 201e, all the dust is concentrated on the door body 201f and enters the air inlet pipe 102 by the airflow. The suction force of the air can make the drive plate 203c rotate. The rotation of the drive plate 203c drives the door hinge 201g to rotate, and the door hinge 201g drives the protective plate 203e. The rotation of the protective disc 203e applies pressure to the torsion spring 203f, causing the door 201f to open. By placing the collection box under the door 201f, the door 201f discharges the collected dust into the collection box, thus completing the collection of dust after cleaning. After the dust is discharged, the dust collector 101 has finished its work, and there will be no wind blowing on the drive plate 203c. At this time, the force of the torsion spring 203f's rebound can drive the door 201f to close for the next use.

[0064] 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.
