Technical Field

[0001] This utility model relates to the field of protective netting equipment technology, and in particular to dynamic self-cleaning protective netting. Background Technology

[0002] Protective nets are a very common item in daily life, applicable to various industries, such as rockfall protection nets, mine landslide prevention nets, construction site protection nets, and household mosquito screens. They are also used in the hydraulic stations of cotton processing equipment to prevent cotton or cotton debris from entering and affecting the normal operation of the equipment.

[0003] However, during processing, cotton or cotton scraps can easily and quickly adhere to the protective netting, requiring frequent maintenance by staff, which greatly affects work efficiency and is also labor-intensive. Utility Model Content

[0004] This application provides a dynamic self-cleaning protective net that can automatically clean the adhering materials on the protective net during dynamic protection, which can effectively reduce labor intensity and improve work efficiency.

[0005] This application provides a dynamic self-cleaning protective net, including a square main frame. The two opposite sides of the main frame are the air inlet side and the air outlet side, respectively. A driven roller is provided at the top of the main frame. From top to bottom, an active roller, a cleaning roller, and a deburring roller are arranged in sequence at the bottom of the main frame. Both the active roller and the cleaning roller are rotatably disposed within the main frame. A discharge port is provided on the bottom wall of the main frame. The protective net is wound around the driven roller and the active roller in a transmission cooperation manner. The outer surface of the cleaning roller is provided with cleaning brushes that can extend to the active roller.

[0006] During operation, on the air inlet side, the protective net is driven by the active roller and the driven roller to rotate in the direction facing the cleaning roller. The cleaning roller rotates in the same direction, thereby transferring the adhering material on the protective net to the cleaning brush on the side close to the active roller. Subsequently, during the rotation of the cleaning roller, the adhering material on the cleaning brush is removed by the deburring process.

[0007] In one possible implementation, a geared motor is mounted on one side of the bottom of the main frame. A first gear is sleeved on the rotating shaft of the geared motor. The cleaning roller is coaxially connected to a cleaning shaft. A second gear and a third gear are sleeved at intervals on the cleaning shaft. The drive roller is coaxially connected to a drive shaft. A fourth gear is sleeved on the drive shaft. The first gear engages with the second gear through a first rack, and the third gear engages with the fourth gear through a second rack.

[0008] In one possible implementation, the deburring is located near the air outlet side, and the deburring tip extends obliquely upward toward the air inlet side.

[0009] In one possible implementation, the main frame has protective plates on all four sides of one side of the air inlet side, and the protective plates cover the gaps between the protective net, the driven roller, the cleaning roller and the outer side of the main frame.

[0010] In one possible implementation, the main frame has a reinforcing rib on one side of the air outlet side to connect the outer side of the main frame.

[0011] In one possible implementation, the reinforcing ribs are arranged in a cross pattern.

[0012] In one possible implementation, the main frame has an annular sealing gasket along the outer edge on one side of the air outlet side.

[0013] In one possible implementation, the protective net is a nylon protective net, and the burr removal is done with steel teeth.

[0014] Beneficial effects: Compared with the prior art, the dynamic self-cleaning protective net provided in this application sets the protective net to a continuously rotating dynamic mode. During the rotation, the material adhering to the protective net is transferred to the cleaning brush of the cleaning roller. Then, during the rotation of the cleaning roller, the adhering material is removed by the deburring below and finally discharged through the discharge port at the bottom. This allows the protective net to not only play a normal protective role, but also automatically clean the adhering material, saving the work of frequent manual maintenance, effectively reducing labor intensity and improving work efficiency.

[0015] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] refer to Figures 1 to 5 This application provides a dynamic self-cleaning protective net, including a square main frame 10. The two opposite sides of the main frame 10 are the air inlet side and the air outlet side, respectively. A driven roller 11 is provided at the top of the main frame 10, while a driven roller 12, a cleaning roller 13, and a deburring roller 14 are arranged sequentially from top to bottom at the bottom of the main frame 10. The driven roller 12 and the cleaning roller 13 are directly opposite the driven roller 11, and both are rotatably mounted within the main frame 10. Furthermore, a discharge port 101 is provided on the bottom wall of the main frame 10. A protective net 15 is wound around the driven roller 11 and the driven roller 12 in a transmission-coordinated manner. The protective net 15 is preferably a nylon protective net, which is sturdy and durable. The deburring roller 14 is preferably made of steel teeth. The outer surface of the cleaning roller 13 is provided with cleaning brushes 131 that extend to the driven roller 12. The cleaning brushes 131 are preferably densely packed plastic spikes or needles, similar to a shoe brush.

[0025] During operation, on the air inlet side, the protective net 15 is driven by the active roller 12 and the driven roller 11 to rotate in the direction facing the cleaning roller 13. The cleaning roller 13 rotates in the same direction, thereby transferring the adhering material on the protective net 15 to the cleaning brush 131 on the side close to the active roller 12. Then, during the rotation of the cleaning roller 13, the adhering material on the cleaning brush 131 is removed by the deburring 14 and then discharged from the discharge port 101 below.

[0026] Therefore, the dynamic self-cleaning protective net provided in this application can not only play a protective role, but also automatically clean off the adhering material in the process of dynamic protection by the cooperation of cleaning brush 131 and deburring 14, which saves the work of frequent manual maintenance and treatment, greatly reduces labor intensity and improves work efficiency. The adhering material can be cotton, cotton scraps, silk threads or other fluffy materials, which are not specifically limited here.

[0027] Taking the rotation of the protective net 15 on the air inlet side facing the cleaning roller 13 as clockwise as an example, the cleaning roller 13 also rotates clockwise. In this way, when the bottom of the protective net 15 moves from left to right, the top of the cleaning roller 13 moves from right to left. This allows the material adhering to the protective net 15 to be transferred to the cleaning brush 131 of the cleaning roller 13. When the cleaning brush 131 rotates to the bottom, the deburring 14 below will remove the material adhering to the cleaning brush 131 and then discharge it through the discharge port 101, thus achieving automatic cleaning.

[0028] In one embodiment, a geared motor 16 is mounted on one side of the bottom of the main frame 10. A first gear 161 is sleeved on the rotating shaft of the geared motor 16. The cleaning roller 13 is coaxially connected to a cleaning shaft, and a second gear 132 and a third gear 133 are spaced apart on the cleaning shaft. The drive roller 12 is coaxially connected to a drive shaft, and a fourth gear 121 is sleeved on the drive shaft. The first gear 161 is driven by the second gear 132 through a first rack, and the third gear 133 is driven by the fourth gear 121 through a second rack. Thus, the cleaning roller 13 and the drive roller 12 can be driven to rotate simultaneously by a single geared motor, which can reduce equipment costs, save equipment installation space, and make the structure of the dynamic self-cleaning protective net more compact.

[0029] In one embodiment, the deburring 14 is located near the air outlet side, and the burr head 141 of the deburring 14 extends obliquely upward towards the air inlet side, thereby facilitating the removal of adhering material on the cleaning brush. At the same time, the removed adhering material can be discharged from the discharge port 101 below.

[0030] Materials such as cotton, cotton scraps, and fluff are usually attached to the protective net 15 and cleaning brush 131 by hooking or hooking, rather than being firmly attached. Therefore, the material attached to the cleaning brush 131 can be easily removed by removing the burrs 14.

[0031] To ensure the normal rotation of the protective net, the active roller 12, the driven roller 11, and the cleaning roller 13, gaps are required between them and the outer edge of the main frame 10. However, some external materials, such as cotton and cotton lint, can easily pass through these gaps, causing the protection to fail. Therefore, in one embodiment, the main frame 10 is provided with protective plates 17 on all four sides of the air inlet side. At the same time, the protective plates 17 cover the gaps between the protective net 15, the driven roller 11, the cleaning roller 13 and the outer edge of the main frame 10, to ensure the reliability and comprehensiveness of the protection of the dynamic self-cleaning protective net.

[0032] In one embodiment, the main frame 10 is provided with a reinforcing rib 18 on one side of the air outlet side to connect the outer side of the main frame 10, thereby improving the structural strength and overall structural stability of the main frame 10, while having a very limited impact on the air outlet.

[0033] More preferably, the reinforcing ribs 18 are distributed in a cross shape, for example, distributed in the horizontal and vertical directions respectively to form a cross, or for example, they are inclined to connect the four corners of the main frame to form a cross.

[0034] In one embodiment, the main frame 10 is provided with an annular sealing gasket 19 on the outer side of the air outlet side, so that the dynamic self-cleaning protective net can fit tightly against the hydraulic station equipment when installed on the hydraulic station to ensure its protective performance.

[0035] It should be noted that the terms "first, second, third and fourth" used in this application are for descriptive purposes only, do not indicate any order, and should not be construed as indicating or implying relative importance. These terms can be interpreted as names.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
