[0037] The embodiment provides a kind of winding and unwinding dustproof device, as shown in Figures 1-4 The device includes dustproof curtain 20 and winding mechanism 30.Dustproof curtain 20 includes opening 21 and covering portion 22 arranged along the length direction thereof, and dustproof curtain 20 has taking and placing position and covering position.When dustproof curtain 20 is at taking and placing position, opening 21 is directly opposite dustproof piece 10, so that dustproof piece 10 can be taken out from opening 21.When dustproof curtain 20 is at covering position, covering portion 22 can cover workpiece 100.Winding mechanism 30 can drive dustproof curtain 20 to reciprocate between taking and placing position and covering position.
[0038] In the dustproof device, the dustproof member 10 is placed on the workpiece 100, so that dust and metal scraps can be prevented from falling on the workpiece 100 when the workpiece 100 is transported or stored; when the workpiece 100 is needed, the dustproof member 10 can be removed from the workpiece 100 through the opening 21, and before the dustproof member 10 is stored, the winding mechanism 30 can wind the dustproof curtain 20, so that the covering part 22 can cover the workpiece 100, and at this time, the dust and metal scraps falling from the dustproof member 10 can directly fall on the covering part 22, thereby protecting the workpiece 100. The winding mechanism 30 can drive the dustproof curtain 20 to reciprocate between the taking and placing positions and the covering position, so that the dustproof member 10 can be placed back to the original position to meet the actual needs, and the convenience of use is ensured.
[0039] It should be noted that in the present embodiment, the dustproof member 10 can be a flexible structure such as a dustproof film, or a rigid structure such as a dustproof cover, as long as it has a dustproof effect and does not scratch the workpiece 100, and the present embodiment is not limited in particular.
[0040] Specifically, as shown in Figures 1-4 The winding mechanism 30 includes first winding assemblies 31 and second winding assemblies 32 arranged on both sides of the workpiece 100, and the two ends of the dustproof curtain 20 are connected to the first winding assemblies 31 and the second winding assemblies 32 along the length direction thereof; when the first winding assemblies 31 wind and the second winding assemblies 32 unwind, the dustproof curtain 20 can be switched from the taking and placing position to the covering position. It should be noted that although the names defined in the present embodiment are the first winding assemblies 31 and the second winding assemblies 32, both of them actually have the functions of winding and unwinding, and in the present structure, the winding and unwinding of the first winding assemblies 31 and the second winding assemblies 32 can quickly and smoothly switch the dustproof curtain 20 between the taking and placing position and the covering position according to the actual needs, thereby ensuring the convenience of use and the stability of winding.
[0041] It should be noted that the first winding assemblies 31 and the second winding assemblies 32 each include a driving motor and a winding roller, the driving motor can drive the winding roller to rotate, and the two ends of the dustproof curtain 20 are connected to the two winding rollers along the length direction thereof, so that the winding or unwinding of the dustproof curtain 20 can be completed when the winding rollers rotate, the structure is simple, the operation is convenient, and the use effect is good.
[0042] Further, the winding and unwinding dustproof device further comprises a support 50, wherein the support 50 and the workpiece 100 are placed on a support surface, the winding mechanism 30 is arranged on the support 50, and the height of the winding mechanism 30 is higher than that of the workpiece 100, so as to facilitate installation and avoid interference between the winding dustproof curtain 20 and the workpiece 100 during winding, thereby avoiding scratching of the dustproof curtain 20 or the workpiece 100 and ensuring good stability.
[0043] In order to further improve the winding and unwinding effect, as shown in Figure 1 and Figure 2 , a slide rail 33 is arranged between the first winding assembly 31 and the second winding assembly 32, which can support and guide the dustproof curtain 20 during winding. The slide rail 33 can play a certain supporting role during winding of the dustproof curtain 20, thereby avoiding collapse of the dustproof curtain 20 during winding, and can guide the movement of the dustproof curtain 20 to ensure good winding effect.
[0044] In addition, as shown in Figure 1 and Figure 2 , the dustproof curtain 20 is provided with a slide rail 33 on both sides in the width direction. In this structure, both sides of the dustproof curtain 20 can play a supporting role to ensure that both sides of the dustproof curtain 20 will not collapse, and the winding smoothness can be further improved. In addition, the slide rail 33 has a limiting portion, which can limit the dustproof curtain 20 from both sides while guiding, thereby avoiding deviation of the dustproof curtain 20 from the winding direction and ensuring good winding effect.
[0045] Considering that the covering portion 22 has a certain weight, and when the dustproof curtain 20 is in the covering position, the covering portion 22 is suspended above the workpiece 100, at this time the center of the covering portion 22 will be concave downward, which may cause damage to the surface of the dustproof curtain 20 or the workpiece 100. To solve this problem, as shown in Figure 1 and Figure 5 , a supporting mechanism 40 is arranged between the first winding assembly 31 and the second winding assembly 32, which can support the bottom end of the dustproof curtain 20. In this structure, the supporting mechanism 40 can lift the covering portion 22 upward, thereby effectively avoiding the concave of the covering portion 22 at the center position due to its own weight, and avoiding contact with the workpiece 100, thereby ensuring good dustproof covering effect.
[0046] In addition, as shown in Figure 1As shown, the support mechanism 40 is arranged at intervals along the length direction of the dustproof curtain 20. This structure can further improve the support effect on the dustproof curtain 20. Even if the covering part 22 of the dustproof curtain 20 has a large area, the plurality of support mechanisms 40 can simultaneously support the covering part 22, thereby preventing the phenomenon of local collapse of the covering part 22, and further generating a good covering effect.
[0047] Further, the dustproof curtain 20 is provided with a plurality of support mechanisms 40 on both sides in the width direction, and is symmetrically arranged along the width direction of the dustproof curtain 20. This structure can simultaneously support the covering part 22 from both sides of the dustproof curtain 20, thereby reducing the length and complexity of the support structure, further improving the support effect, and preventing the covering part 22 from tilting to one side and interfering with the workpiece 100.
[0048] In order to improve the practicability of the support mechanism 40, as shown in Figure 5 The support mechanism 40 is arranged on the support 50 and has a support position and a folding position. The support mechanism 40 includes a support rod 44. When the support mechanism 40 is in the support position, the support rod 44 is perpendicular to the length direction of the dustproof curtain 20 to support the dustproof curtain 20. When the support mechanism 40 is in the folding position, the support rod 44 is parallel to the length direction of the dustproof curtain 20. In this structure, when the covering part 22 needs to be supported, the support rod 44 is placed in the support position (the support rod 44 is perpendicular to the length direction of the dustproof curtain 20). When the dustproof curtain 20 is in the taking and placing position, the support rod 44 only needs to be placed in the folding position. At this time, the support rod 44 is parallel to the length direction of the dustproof curtain 20, that is, it is attached to the side edges on both sides of the support 50. At this time, it will not hinder the removal of the dustproof piece 10 from the opening 21, ensuring the practicability and good use effect.
[0049] In order to further simplify the overall structure of the support mechanism 40, as shown in Figure 5 The support mechanism 40 further includes a connecting piece 42 and a rotating shaft 43. The extension end of the driving piece 41 is hinged to the connecting piece 42. The other end of the connecting piece 42 is in transmission connection with the rotating shaft 43. The other end of the rotating shaft 43 is in transmission connection with the support rod 44, so that the extension end of the driving piece 41 can drive the support rod 44 to rotate between the support position and the folding position. In this structure, the driving piece 41 can drive the connecting piece 42 to rotate through the extension end. The connecting piece 42 can further drive the connecting piece 42 to rotate through the rotating shaft 43, thereby ensuring good convenience, improving the automation degree of the device, and reducing the labor cost.
[0050] It is worth mentioning that in the embodiment, the driving member 41 is a telescopic cylinder, which is arranged on the support 50 at both sides of the dustproof curtain 20 in the width direction by virtue of its small volume and simple structure, and the telescopic direction is parallel to the length direction of the dustproof curtain 20, and the rotating shaft 43 is arranged on the support 50 in the vertical direction and can rotate around the vertical direction. Such arrangement can further reduce the space occupation on the basis of simplifying the structure, so that the supporting mechanism 40 is more convenient to install at the bottom end of the dustproof curtain 20, and the difficulty of installation and disassembly is reduced.
[0051] In addition, in some working conditions where the dustproof curtain 20 has a large area, the supporting mechanism 40 also needs to act to support the dustproof curtain 20 when the dustproof curtain 20 is in the covering position. At this time, if the opening 21 is also large, the supporting rod 44 does not have enough supporting position, and methods such as shortening the length of the supporting rod 44 or controlling the rotation angle of the supporting rod 44 to be less than 90° can be used to make the supporting rod 44 support at the edge of the dustproof curtain 20, so as to realize effective support without interference.
[0052] In addition, as shown in Figure 1 , the winding and unwinding dustproof device further comprises a dust collecting box, and a brush is designed in the dust collecting box. The brush abuts against the dustproof curtain 20, and when the winding mechanism 30 drives the dustproof curtain 20 to move, the brush can move relative to the dustproof curtain 20 to clean the dustproof curtain 20. In this structure, when the dustproof curtain 20 is wound, it can move relative to the brush, and the dust and debris on the dustproof curtain 20 can be collected into the dust collecting box through the friction generated by the relative movement and the blocking effect of the brush itself, so as to ensure that the dustproof curtain 20 will not drive its own dust and debris to the workpiece 100, thereby ensuring good dustproof effect.
[0053] The use process of the winding and unwinding dustproof device in the embodiment will be described in combination with the drawings:
[0054] Firstly, as shown in Figure 1 and Figure 2 , the dustproof curtain 20 is placed in the taking and placing position, and at this time the opening 21 faces the workpiece 100, and the dustproof member 10 can be removed through the opening 21;
[0055] Secondly, the dustproof curtain 20 is wound by the cooperation of the first winding assembly 31 and the second winding assembly 32 to move it from the taking and placing position to the covering position, and at this time the dustproof member 10 can be arranged and stored;
[0056] Finally, the dustproof curtain 20 is moved to the taking and placing position again by the cooperation of the first winding assembly 31 and the second winding assembly 32, and after the workpiece 100 is taken and placed, the dustproof member 10 is re-covered on the workpiece 100.
[0057] To sum up, the winding and unwinding dustproof device in the embodiment can effectively avoid foreign matters from falling on the workpiece 100 when the dustproof piece 10 on the surface of the workpiece 100 is uncovered, thereby generating a good dustproof effect and further ensuring the use effect of the workpiece 100.
[0058] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application.
