AI Technical Summary

Technical Problem

During the use of rodless cylinders, dust is easily accumulated on the cylinder block and cylinder barrel, resulting in increased sliding friction, susceptible to squeeze by foreign objects, affecting sliding and even causing equipment failure.

Method used

Design a dust-proof rod-free cylinder, including a cylinder barrel, both end covers, cylinder block and bottom openings. A hollow slider is provided on the dust cover, the bottom of the slider is connected to the cylinder, and a brush is provided on the inner wall where the slider is in contact with the surface of the dust cover.

Description

Technical Field

[0001] The invention relates to the field of rodless cylinders, in particular to a dustproof rodless cylinder. Background Art

[0002] During the use of rodless cylinders, dust is easily accumulated on the cylinder body and cylinder barrel, which causes the sliding friction to increase when the cylinder body moves on the cylinder barrel. At the same time, it is easy to be squeezed by other foreign objects, affecting sliding and even causing equipment failure. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a dustproof rodless cylinder.

[0004] The present invention discloses a dustproof rodless cylinder, comprising a cylinder barrel, two end covers arranged at two ends of the cylinder barrel and a cylinder body arranged on the cylinder barrel, and also comprising a dust cover with an opening at the bottom, one end of the dust cover is connected to one of the end covers, and the other end is connected to the other end cover, a sliding sleeve on the dust cover is provided with a hollow sliding block, and the bottom of the sliding block is connected to the cylinder body.

[0005] Preferably, the bottom end of the dust cover is connected to a dust plate that matches it, and when the slider drives the cylinder to move, the positions of the two ends of the dust plate remain unchanged.

[0006] Preferably, the dustproof plate is integral, the bottom plate of the slider is provided with a sliding groove which runs transversely therethrough, the dustproof plate passes through the sliding groove, and both ends of the dustproof plate are connected to the dustproof cover.

[0007] Preferably, the inner wall of the slide groove is provided with a brush, and the brush can contact the dustproof plate.

[0008] Preferably, the dustproof plate is of group type, comprising two slide plate groups symmetrically arranged on both sides of the slider, the inner end of each slide plate group is connected to the slider, and the outer end is connected to the protective cover, and each slide plate group comprises a number of slide plates superimposed on each other, and each adjacent slide plate is slidably connected.

[0009] Preferably, between every two adjacent slide plates, one of the slide plates is provided with at least one T-shaped slide groove, and the other slide plate is connected with at least one pulley matched with the T-shaped slide groove.

[0010] Preferably, the slide plate includes a dustproof bottom plate and two dustproof side plates symmetrically arranged on both sides of the dustproof bottom plate, and the cross section of each dustproof side plate is arc-shaped.

[0029] The present invention discloses a dustproof rodless cylinder, referring to Figure 1 , Figure 2 , Figure 3 , including a cylinder 1, two end covers 2 arranged at both ends of the cylinder 1 and a cylinder body 3 arranged on the cylinder 1, and also including a dust cover 4 with an opening at the bottom, one end of the dust cover 4 is connected to one of the end covers 2, and the other end is connected to the other end cover 2. A hollow slider 5 is provided on the sliding sleeve of the dust cover 4, and the bottom of the slider 5 is connected to the cylinder body 3, so that when the cylinder body 3 moves, the slider 5 can be driven to move synchronously, and the inner wall where the slider 5 contacts the surface of the dust cover 4 is provided with a brush (not shown in the figure), and the dust on the dust cover can be cleaned by the brush. Further, refer to Figure 4 , Figure 6 The bottom of the dust cover 4 is connected to a dust plate 6 that matches it. When the slider 5 drives the cylinder 3 to move, the positions of the two ends of the dust plate 6 remain unchanged, so that during the movement of the slider 5, the positions of the two ends of the dust plate 6 are prevented from moving and occupying more space. Figure 4 , Figure 5The dustproof plate 6 is integral, and the bottom plate of the slider 5 is provided with a slide groove 7 which runs transversely therethrough. The dustproof plate 6 passes through the slide groove 7, and both ends are connected to the dust cover 4. When the slider 5 moves, the dustproof plate 6 slides in the slide groove 7, which can not only further prevent the influence of dust or foreign matter on the rodless cylinder, but also ensure that the slider 5 is completely retained to the outside to be connected to the driven part without affecting the slider 5. Furthermore, the inner wall of the slide groove 7 is provided with a brush (not shown), which can contact with the dustproof plate 6, and the dust on the dustproof plate 6 can be cleaned by the brush. Refer to Figure 6 , Figure 7 , Figure 8 The dustproof plate 6 is a group type, and the dustproof plate 6 includes two slide plate groups 61 symmetrically arranged on both sides of the slider 5. The inner end of each slide plate group 61 is connected to the slider 5, and the outer end is connected to the dust cover 4. Each slide plate group 61 includes a plurality of slide plates 611 superimposed on each other. Each adjacent slide plate 611 is slidably connected. During the movement of the slider 5, the slide plates 611 slide between each other, so that the slide plate group 61 always performs closed protection on the rodless cylinder. Further, referring to Figure 8 Between each two adjacent slides 611, one slide 611 is provided with at least one T-shaped slide groove 8, and the other slide 611 is connected with at least one pulley 9 adapted to the T-shaped slide groove 87, and the slides between the slides 611 are realized by rolling the pulley 9 in the T-shaped slide groove 8. Figure 7 The slide plate 611 includes a dustproof bottom plate 6111 and two dustproof side plates 6112 symmetrically arranged on both sides of the dustproof bottom plate 6111.

The dust on the dust cover can be cleaned by the brush. The bottom of the slider 5 is connected to the cylinder body 3. When the cylinder body 3 moves on the cylinder barrel 1, the slider 5 can be driven to slide on the dust cover 4, and then the slider 5 is connected to the driven part instead of the cylinder body 3, and the driven part is driven to work by the slider 5. Under the action of the dust cover 4, dust accumulation on the cylinder barrel 1 and the influence of foreign matter on the cylinder body 3 are effectively prevented, thereby extending the service life of the rodless cylinder.

[0032] Embodiment 2: In this embodiment, a dust cover 4 and a dust plate 6 are used to protect the rodless cylinder, and the dust plate 6 is an integral type.

The bottom plate of the slider 5 is provided with a horizontally penetrating slide groove 7. The dustproof plate 6 passes through the slide groove 7 and is connected to the dust cover 4 at both ends. When the slider 5 moves, the dustproof plate 6 slides in the slide groove 7, which can not only further avoid the influence of dust or foreign matter on the rodless cylinder, but also ensure that the slider 5 is completely retained to the outside and connected to the driven part, without affecting the slider 5. Further, the inner wall of the slide groove 7 is provided with a brush (not shown), which can contact the dustproof plate 6, and the dust on the dustproof plate 6 can be cleaned by the brush. The bottom of the slider 5 is connected to the cylinder body 3. When the cylinder body 3 moves on the cylinder barrel 1, the slider 5 can be driven to slide on the dust cover 4, and then the slider 5 is connected to the driven part instead of the cylinder body 3.
