Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to a rolling curtain filter. Background Art

[0002] Automatic rolling-up filters are widely used in production and life fields due to their good comprehensive ventilation and dust removal performance, high strength, high temperature resistance and good chemical stability. Automatic rolling-up filters use a pressure differential switch and a motor to automatically replace the filter material, thereby extending the filtration time. Automatic rolling-up filters are generally equipped with two motors, one of which rotates to unfold the filter material, and the other rotates to reel in the unfolded and used filter material. When using the automatic rolling-up filter, the filter cloth needs to be installed on the rollers at both ends. However, the existing automatic rolling-up filters require specific tools when installing and disassembling the rollers, which makes the installation and disassembly time-consuming and labor-intensive, and inconvenient to use.

[0003] For example, an automatic rolling filter disclosed in a Chinese patent document (publication number: CN211562258U) uses a segmented detector to enable the rolling filter cloth to move between the first winding core shaft and the second winding core shaft under the drive of the first drive motor and the second drive motor. The positioning mark at the edge of the rolling filter cloth can be identified by the segmented detector, thereby accurately positioning the rolling filter cloth, so that the rolling filter cloth can be set to automatically switch modes for air filtration according to usage needs.

[0004] However, in actual use, the roller filter cloth is a consumable. Therefore, when the roller core shaft needs to be disassembled to replace the roller filter cloth, specific tools are required to disassemble the roller core shaft, and the disassembly process is relatively cumbersome, time-consuming and labor-intensive, resulting in longer downtime for replacement and reduced filtration efficiency.

[0026] A disassembly device is provided on one inner wall of the positioning groove 7 , and the disassembly device includes a cross plug block 8 , and one side surface of the cross plug block 8 is fixedly connected to one inner wall of the positioning groove 7 .

[0027] A counterweight block 81 is fixedly connected to the lower surface of the rotating block 6, and a positioning block 82 is movably inserted into the inner wall of the positioning groove 7. The counterweight block 81 uses gravity to make the positioning groove 7 on the rotating block 6 always open upward, thereby facilitating the installation of the positioning block 82. A handle 83 is fixedly connected to the upper surface of the positioning block 82, and the handle 83 facilitates the movement of the positioning block 82. A cross slot 84 is opened on one side surface of the positioning block 82, and the inner wall of the cross slot 84 is movably inserted into the outer surface of the cross plug block 8. By the plug-in limit of the cross slot 84 and the cross plug block 8, the positioning block 82 is driven to rotate by the rotation of the rotating block 6. A movable groove 85 is provided on the other side surface of the positioning block 82. The inner top wall and the inner bottom wall of the movable groove 85 are provided with symmetrically distributed limiting slide grooves 86. The inner wall of the limiting slide groove 86 is slidably connected to the limiting slider 87. The opposite surfaces of the two limiting sliders 87 are fixedly connected with the mounting blocks 88. The limiting slide groove 86 and the limiting slider 87 cooperate with the mounting block 88 to achieve stable movement.

[0028] The outer surface of the mounting block 88 is movably sleeved with the inner wall of the movable groove 85, and a support spring 89 is fixedly connected to the surface of one side of the mounting block 88. The support spring 89 plays a role of elastic reset, and one end of the support spring 89 is fixedly connected to the inner wall of one side of the movable groove 85. The opposite surfaces of the two mounting blocks 88 are fixedly connected with mounting rollers 810, and the outer surface of one of the mounting rollers 810 is wrapped with a filter cloth 811, and the two mounting rollers 810 play the role of cooperating with the winding of one end and the stretching of the other end of the filter cloth 811, and one end of the filter cloth 811 is wrapped with the outer surface of the other mounting roller 810. The upper surface of one of the mounting frames 2 is hinged with a dust cover 812 through a hinge, and the dust cover 812 plays a role of dustproof protection for the stored filter cloth 811.

[0029] By providing a convenient disassembly device, it is possible to facilitate the disassembly and installation of the installation roller 810, saving time and effort, thereby improving the replacement efficiency of the filter cloth 811, thereby reducing the downtime of the filter body 1 and improving the filtering efficiency.

[0030] Working principle: Step 1, during disassembly, the two positioning blocks 82 are relatively moved by the handle 83, and the movement of the positioning block 82 causes the cross slot 84 to be separated from the limit of the cross insert block 8, and the cooperation between the limit slide 86 and the limit slider 87 causes the mounting block 88 to squeeze the support spring 89, and then the positioning block 82 is lifted up by the handle 83 to be separated from the positioning slot 7, and then the mounting roller 810 can be taken out to replace the filter cloth 811;

[0031] Step 2: During installation, due to the gravity of the counterweight block 81 below the rotating block 6, the notch of the positioning slot 7 is always in an upward state, and the two positioning blocks 82 are relatively moved by the handle 83, and the mounting block 88 squeezes the support spring 89 through the cooperation of the limiting slide groove 86 and the limiting slide block 87, and then the positioning block 82 is inserted into the positioning slot 7 and the handle 83 is released;

[0032] Step three, at this time, the elastic force of the support spring 89 drives the positioning block 82 to reset through the mounting block 88, and the reset movement of the positioning block 82 causes the cross slot 84 on one side to be plugged and limited with the cross plug block 8. When the servo motor 3 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the rotating block 6 to rotate, and the rotation of the rotating block 6 drives the positioning block 82 to rotate through the limiting cooperation between the cross slot 84 and the cross plug block 8, thereby driving the mounting roller 810 to rotate through the cooperation between the positioning block 82 and the mounting block 88, and stably rotating through the cooperation between the driven rod 5 and the bearing.
