Description

Technical Field

[0001] This application relates to the field of dust removal technology in packaging lines, and in particular to a protective cover that reduces dust scattering from the bag body. Background Technology

[0002] In the palletizing process of the packaging industry, packaging machines cannot achieve complete sealing, and the bags have vents, causing some dust to escape. Therefore, bags containing dusty items become contaminated with dust. Existing dust collection systems only have collection hoods at their suction inlets, thus only collecting dust within the area of ​​the hood. This results in a small dust collection range and poor dust removal efficiency, causing most of the dust to scatter outside the collection hood, such as onto equipment, the ground, and into the air. This not only pollutes the working environment and wastes resources but also affects subsequent processing steps and increases the workload of workers. Utility Model Content

[0012] By adopting the above technical solution, when in use, the staff starts the cleaning motor, and the output shaft of the cleaning motor rotates, which drives the cleaning brush to rotate, so that the cleaning brush can clean the inner wall of the conveyor protective cover more thoroughly.

[0013] Optionally, the auxiliary component includes fan blades fixedly connected to the output shaft of the drive motor, and multiple fan blades are arranged at intervals along the circumferential direction of the motor output shaft.

[0014] By adopting the above technical solution, when in use, the rotation of the output shaft of the cleaning motor drives the fan blades to rotate, which increases the airflow inside the conveyor protective cover and the dustproof protective cover, thereby improving the dust recovery efficiency.

[0015] Optionally, the auxiliary component may further include a protective ring fixedly connected to the end of the fan blade away from the output shaft of the drive motor.

[0016] By adopting the above technical solution, the protective ring reduces the possibility of the fan blades damaging other items inside the conveyor shield during operation.

[0017] Optionally, the drive assembly includes a screw disposed on the side of the front mounting plate away from the ground, a guide rod disposed on the side of the front mounting plate away from the ground, and a rotary motor disposed on the side of the conveyor guard away from the ground, the output shaft of the rotary motor being connected to the screw.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a protective cover for reducing dust dispersion from the bag body. (Refer to...) Figure 1 A protective cover for reducing dust scattering from the bag body includes a front support frame 1, a rear support frame 2, a connecting frame 3 for connecting the front support frame 1 and the rear support frame 2, a collection cover 4 installed on the side of the rear support frame 2 near the ground, a conveying protective cover 5 installed on the side of the front support frame 1 away from the ground, a dustproof protective cover 6 installed on the side of the rear support frame 2 away from the ground, and a dust collection device 7 installed inside the dustproof protective cover 6. Both the conveying protective cover 5 and the dustproof protective cover 6 are made of transparent acrylic material to facilitate real-time observation of dust collection by staff.

[0032] The front support frame 1 includes multiple support columns 11, a front mounting frame 12 fixedly connected to the support columns 11 on the side away from the ground, and a front mounting plate 13 disposed on the side of the front mounting frame 12 away from the ground. Two front mounting plates 13 are disposed opposite each other along the length of the front mounting frame 12. A belt conveyor (not shown in the figure) is disposed between the front mounting frames 12. The conveyor guard 5 is installed on the side of the front mounting plate 13 away from the ground. The belt conveyor is prior art and will not be described in detail in this application.

[0033] The rear support frame 2 includes a rear support frame 21 installed at the end of the front support frame, a non-powered roller (not shown) rotatably connected in the rear support frame 21, and a connecting column 22 fixedly connected between the rear support frame 21 and the support column 11. The rear support frame 21 is inclined. The end of the rear support frame 21 furthest from the front support frame is located on the side of the front support frame closest to the ground. There are two connecting columns 22 arranged opposite each other, and multiple non-powered rollers are spaced apart. A dustproof cover 6 is installed on the side of the rear support frame 21 furthest from the ground. A collection cover 4 is located between two connecting columns 22.

[0034] Reference Figure 1 and Figure 2 The vacuuming device 7 includes a connecting block (not shown) installed inside the dustproof protective cover 6, an upper vacuum cover 71 installed on the connecting block, a vacuum pipe (not shown) located on the side of the upper vacuum cover 71 away from the rear support frame 21, a dust collector (not shown) for providing airflow, an upper cleaning roller 72 located inside the upper vacuum cover 71, an upper drive motor 73 for driving the upper cleaning roller 72 to rotate, a cleaning air knife (not shown) located inside the upper vacuum cover 71, a lower cleaning roller 74 rotatably connected to the rear support frame 21, and a lower drive motor 75 for providing power to the lower cleaning roller 74. The lower drive motor 75 is fixedly connected to the side wall of the rear support frame 21 away from the lower cleaning roller 74, and the output shaft of the lower drive motor 75 is fixedly connected to the end of the cleaning roller. The dust collector, vacuum pipe, and cleaning air knife are all existing technologies.

[0035] In operation, the operator starts the upper drive motor 73 and the lower drive motor 75. The output shaft of the upper drive motor 73 rotates, driving the upper cleaning roller 72 to rotate, and the output shaft of the lower drive motor 75 rotates, driving the lower cleaning roller 74 to rotate. The operator starts the belt conveyor, which transports the bag to the rear support frame 21. Under the weight of the bag itself, the bag slides on the unpowered roller. When the bag slides to below the upper dust collection hood 71, the dust collector helps the upper dust collection hood 71 to absorb the dust adhering to the surface of the bag. As the bag passes by, the upper cleaning roller 72, located inside the upper dust collection hood 71, rotates, thereby sweeping away the dust adhering to the surface of the bag, making it easier for the dust adhering to the surface of the bag to be absorbed by the dust collection hood. At the same time, the conveyor protective cover 5, the dustproof protective cover 6, and the collection cover 4 can collect the scattered dust, reducing the possibility of dust scattering on the equipment and the ground during the cleaning and collection of dust adhering to the bag, protecting the working environment of the operators, and improving the dust recovery efficiency.

[0036] Reference Figure 2 and Figure 3In order to improve the stability and rigidity of the conveyor protective cover 5 and the dustproof protective cover 6, and to facilitate the installation of the conveyor protective cover 5 and the dustproof protective cover 6, a first steel plate bracket 14 is installed on the side of the front mounting plate 13 away from the ground, and a second steel plate bracket 23 is installed on the side of the rear support frame 21 away from the ground. The conveyor protective cover 5 is fixed to the first steel plate bracket 14 by bolts, and the dustproof protective cover 6 is fixed to the second steel plate bracket 23 by bolts.

[0037] Reference Figure 2 In order to assist the lower cleaning roller 74 in cleaning the dust on the surface of the bag and further improve the cleaning efficiency of the bag surface, an air knife 41 is provided inside the collection cover 4, and an air knife connecting rod 42 is provided on the side of the rear support frame 21 near the ground. The air knife 41 is installed on the air knife connecting rod 42 and is used to clean the lower surface of the bag.

[0038] Reference Figure 1 and Figure 3 In order to facilitate the cleaning of dust adhering to the inner wall of the conveyor protective cover 5, and to allow the dust adhering to the inner wall of the conveyor protective cover 5 to disperse in the space formed by the conveyor dust cover and the dust protective cover 6, so as to facilitate collection by the upper dust suction cover 71, further improve the dust recycling efficiency and reduce resource waste, a cleaning device 8 is provided inside the conveyor protective cover 5. The cleaning device 8 is installed on the side of the front mounting plate 13 away from the ground, and two cleaning devices 8 are arranged opposite each other.

[0039] The cleaning device 8 includes a cleaning component 81 and a power component 82, wherein the power component 82 is used to drive the cleaning component 81 to move in the horizontal direction.

[0040] Reference Figure 3 and Figure 4 The cleaning assembly 81 includes a cleaning motor 811 and a cleaning brush fixedly connected to the output shaft of the cleaning motor 811. The cleaning brush includes a fixing plate 812 fixedly connected to the end of the cleaning motor 811 and bristles 813 fixedly connected to the side of the fixing plate 812 near the conveying protective cover 5.

[0041] The power assembly 82 includes a movable plate 821 disposed inside the conveying protective cover 5, a cylinder 822 mounted on the movable plate 821, and a connecting plate 823 fixedly connected to the end of the piston rod of the cylinder 822. The cleaning motor 811 is fixedly connected to the side of the connecting plate 823 away from the cylinder 822. Under normal conditions, the bristles 813 abut against the inner wall of the conveying protective cover 5.

[0042] When in use, the operator starts the cylinder 822 and the cleaning motor 811. The output shaft of the cleaning motor 811 rotates, which drives the cleaning brush fixedly connected to the output shaft of the cleaning motor 811 to rotate, so that the cleaning brush has a larger cleaning range. The piston rod of the cylinder 822 extends, which drives the cleaning component 81 to move along the length of the conveyor protective cover 5, thereby realizing the cleaning of the conveyor protective cover 5.

[0043] Reference Figure 3 In order to enable the cleaning component 81 to clean a wider area of ​​the inner wall of the conveyor protective cover 5, the cleaning device 8 also includes a drive component 83 for driving the cleaning component 81 to move vertically. The drive component 83 includes a screw 831 rotatably connected to the side of the front mounting plate 13 away from the ground, a guide rod 832 rotatably connected to the side of the front mounting plate 13 away from the ground, and a rotating motor 833 disposed on the side of the conveyor protective cover 5 away from the ground. The output shaft of the rotating motor 833 is fixedly connected to the screw 831. The moving plate 821 is threadedly connected to the screw 831 and passes through the guide rod 832, that is, the moving plate 821 is slidably connected to the guide rod 832.

[0044] When in use, the operator starts the rotating motor 833. The output shaft of the rotating motor 833 rotates, which drives the screw 831 to rotate. This causes the connecting plate 823, which is threaded onto the screw 831, to move along the length of the screw 831, thereby driving the power component 82 to move. This causes the cleaning component to move vertically, increasing the cleaning area of ​​the cleaning component on the inner wall of the conveyor protective cover 5.

[0045] Reference Figure 4 In order to increase the cleaning efficiency of the cleaning component on the dust adhering to the inner wall of the conveying protective cover 5, and thus improve the dust collection efficiency of the dust collection device 7, an auxiliary component 84 is also provided on the cleaning component. The auxiliary component 84 includes a fan blade 841 fixedly connected to the output shaft of the drive motor. Multiple fan blades 841 are arranged at intervals along the output shaft of the cleaning motor 811.

[0046] When in use, when the operator starts the cleaning motor 811, the output shaft of the cleaning motor 811 rotates, which drives the fan blade 841 to rotate. This causes air to blow during the cleaning process of the cleaning brush cleaning the inner wall of the conveyor protective cover 5, which further improves the cleaning effect of the cleaning brush on the inner wall of the conveyor protective cover 5, thereby improving the cleaning efficiency of the cleaning component.

[0047] To protect the equipment inside the conveyor shield 5, the auxiliary component 84 also includes a protective ring 842 fixedly connected to the side of the fan blade 841 away from the output shaft of the cleaning motor 811.

[0048] Reference Figure 1 and Figure 3In order to enable the staff to clean the corners of the conveyor protective cover 5 more thoroughly, an auxiliary cleaning component 9 is also provided inside the conveyor protective cover 5 for auxiliary cleaning. The auxiliary cleaning component 9 includes a fan 91 installed on the outer wall of the conveyor protective cover 5, a blower head 92 installed inside the conveyor protective cover 5, and a connecting pipe 93. The connecting pipe 93 is used to connect the fan 91 and the blower head 92. A connecting groove is provided on the conveyor protective cover 5 for the connecting pipe 93 to pass through.

[0049] After the conveyor protective cover 5 has been used for a period of time, the staff turns on the fan 91 and operates the blower head 92 to clean the corners inside the conveyor protective cover 5, thereby improving the dust recovery rate.

[0050] To facilitate the installation of the auxiliary cleaning component 9, multiple fasteners are installed at intervals on the side of the first steel plate support 14 away from the conveying protective cover 5. The fasteners include a fixing block 94 fixedly connected to the first steel plate support 14. The fixing block 94 has a fixing groove on the side away from the first steel plate support 14, and the fixing groove is arc-shaped relative to its two inner walls, forming a fixed space for the installation of the connecting pipe 93. The fixing block 94 is made of an elastic material. Under normal conditions, the connecting pipe 93 is embedded in the fixed space, and the side wall of the blower head 92 abuts against the side wall of the first steel plate support 14.

[0051] The implementation principle of the protective cover for reducing dust scattering from the bag body in this embodiment is as follows: When the bag is transported to the rear support frame 21 by the belt conveyor, it slides towards the dust collection device 7 under its own weight. When the bag passes the dust collection device 7, the upper cleaning roller 72 set in the dust collection device 7, the lower cleaning roller 74 set on the rear support frame 21, and the air blower 41 installed in the collection hood 4 clean the dust attached to the surface of the bag. The dust is dispersed in the air and blocked by the conveying protective cover 5, the dustproof protective cover 6, and the collection hood 4, reducing the pollution to the surrounding environment and facilitating the upper dust collection hood 71 to absorb and collect the dust, thereby improving the dust recycling rate. After a period of use, the staff operates the cleaning device 8 to clean the dust attached to the inner wall of the conveying protective cover 5 and operates the auxiliary cleaning parts 9 to clean the inner corners and other areas of the conveying protective cover 5, further improving the dust recycling efficiency.

[0052] 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.
