[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1-4 An embodiment of the present invention provides a metal hose mesh weaving device without overlapping wires, including a frame 1 and a hollow tube 2 fixed on the frame 1, wherein the hollow tube 2 is used to convey a metal hose 3 for mesh weaving, and also includes a transition tube 4, both ends of which are respectively clamped with the ends of two adjacent metal hoses 3, and the outer diameter of the transition tube 4 is the same as the outer diameter of the metal hose 3.

[0027] Specifically, weaving a stainless steel mesh sleeve on the metal hose 3 (that is, the metal bellows) is a common way to increase the pressure-bearing performance of the metal hose 3, wherein the length of the metal hose 3 is limited, and the weaving of the mesh sleeve is continuous. When the metal hose 3 is sequentially fed into the hollow tube 2, there will be a certain gap between two adjacent metal hoses 3. At this time, the mesh sleeve will be woven empty (that is, there is no support point inside the woven mesh sleeve, and the diameter of this section of the mesh sleeve is smaller), so that the mesh sleeve has a process of covering the tube weaving-empty weaving-covering the tube weaving. Obviously, in this process, the tension of the steel wire 9 used to weave the mesh sleeve goes through a process of large-small-large, which increases the probability of problems with the mesh sleeve at the end of the metal hose 3. The innovation of the embodiment of the present invention is that a transition tube 4 is arranged between two adjacent metal hoses 3, and the two ends of the transition tube 4 are respectively connected with the ends of the two metal hoses 3 (such as interference fit), and the outer diameter of the transition tube 4 is the same as the outer diameter of the metal hose 3 (the same as the outer diameter at the crest of the metal hose 3), so that the mesh is woven on the metal hose 3, the transition tube 4 and the metal hose 3 in sequence, so that the weaving of several or even dozens of metal hoses 3 becomes a continuous process through a plurality of transition tubes 4, and the tension of the steel wire 9 is avoided as much as possible during the weaving process of the mesh, and the mesh is prevented from having a large change as much as possible. Avoid quality problems with the mesh sleeve on the metal hose 3; due to the presence of the transition tube 4, the tension of the plurality of steel wires 9 is basically at a certain value, which will impose multi-directional and uniform restrictions and constraints on the metal hose 3 during the weaving process, forcing the metal hose 3 to pass through the hollow tube 2 relatively straight and move along the axis of the hollow tube 2; since the discrete weaving of the metal hose 3 is transformed into continuous weaving, the weaving equipment can directly bring the corrugated tube into the working area during operation, eliminating the labor of manually pushing the corrugated tube, so as to reduce the impact of uneven weaving caused by manual feeding.

[0028] It should be noted that in the prior art, when the mesh sleeve at the end of the metal hose 3 has overlapping wires, the ends of the metal hose 3 and the mesh sleeve are generally cut to remove the parts with quality problems; in each embodiment of the present invention, a transition pipe 4 is provided to reduce the probability of overlapping wires in the mesh sleeve at the end of the metal hose 3, but the mesh sleeve at the end of the metal hose 3 is also required to be cut to separate the multiple metal hoses 3 woven together.

[0029] An embodiment of the present invention provides a metal hose mesh weaving device without overlapping wires. By setting a transition tube 4, two adjacent metal hoses 3 can be connected together, so that the weaving of two or more metal hoses 3 becomes a continuous process, and when the device weaves the mesh on the two metal hoses 3 successively, the tension of the steel wire 9 decreases and increases with the intermittent process of the mesh empty weaving-covering the tube, and quality problems at the end parts of the two metal hoses 3 are avoided as much as possible.

[0030] In another embodiment provided by the present invention, further, the transition tube 4 is hollow inside, and both ends thereof are configured with a clamping groove 5 adapted to the end of the metal hose 3. Specifically, the outer diameter at the end of the metal hose 3 is generally smaller than the outer diameter at the crest of the metal hose 3, and for this reason, a clamping groove 5 can be provided at the end of the transition tube 4, so that the end of the metal hose 3 can be inserted into the clamping groove 5, so that the crests of two adjacent metal hoses 3 are connected together through the transition tube 4, and then a plurality of transition tubes 4 are used to form a continuous braiding process for a plurality of metal hoses 3.

[0031] Preferably, the end length of the metal hose 3 is greater than the depth of the clamping groove 5. The effect of such a setting is that when the end of the metal hose 3 is inserted into the corresponding clamping groove 5, a part of the end of the metal hose 3 cannot be inserted into the clamping groove 5, so that there is a certain gap between the end of the transition pipe 4 and the wave crest of the metal hose 3 (such as Figure 3 As shown), it is convenient to cut the mesh sleeve later to separate several metal hoses 3.

[0032] In another embodiment provided by the present invention, further, a first fixed disk 6 is fixed on the hollow tube 2. A second fixed disk 7 is fixed on the frame 1. Specifically, in the prior art, a plurality of spindles 8 for conveying steel wires 9 are generally provided on the frame 1, so that the rotation of the plurality of spindles 8 drives the plurality of steel wires 9 to be woven on the metal hose 3. In order to increase the stability of conveying the steel wires 9, a first fixed disk 6 is provided on the hollow tube 2, and a second fixed disk 7 is provided on the frame 1, so that the steel wires 9 can be overlapped on the second fixed disk 7 and the first fixed disk 6 in sequence after passing through the spindles 8, and finally woven at the metal hose 3, thereby improving the stability of weaving the steel wires 9.

[0033] Furthermore, a movable disk 10 is slidably connected to the hollow tube 2 along its axial direction. Specifically, the movable disk 10 is located between the first fixed disk 6 and the second fixed disk 7, and the diameter of the movable disk 10 is larger than the first fixed disk 6 but smaller than the second fixed disk 7; the sliding connection between the movable disk 10 and the hollow tube 2 can adopt the slide rail structure in the prior art, and preferably, the outer wall of the hollow tube 2 is constructed with a slide groove 11 along its axial direction, and the movable disk 10 is slidably connected in the slide groove 11, so that the movable disk 10 is stably slidably connected to the hollow tube 2, and the movable disk 10 is prevented from rotating on the hollow tube 2 as much as possible; the advantage of such a configuration is that, in the above embodiment, a number of steel wires 9 are sequentially overlapped on the second fixed disk 7 and the first fixed disk 6, and a number of steel wires 9 will cross-move on the first fixed disk 6 and the second fixed disk 7 (in the process of weaving), which will cause some of the steel wires to move. 9 There is a phenomenon of wire overlap on the first fixed disk 6 or the second fixed disk 7 (generally, multiple strands of steel wires 9 are arranged at a spindle 8, and multiple steel wires 9 are arranged in sequence. If multiple strands of steel wires 9 are overlapped, the mesh will also be overlapped). For this reason, a movable disk 10 is slidably arranged on the hollow tube 2. During the cross-weaving process of several steel wires 9, the movable disk 10 slides along the hollow tube 2 to resist the crossed steel wires 9, so as to force the steel wires 9 to separate from the first fixed disk 6 and the second fixed disk 7 at the same time. Then the movable disk 10 is away from the steel wire 9, so that the steel wire 9 is overlapped on the first fixed disk 6 and the second fixed disk 7 again under the action of tension. In this way, the steel wire 9 can be forced to oscillate on the first fixed disk 6 and the second fixed disk 7, and the phenomenon of wire overlap of several steel wires 9 can be avoided as much as possible.

[0034] Furthermore, when the movable disk 10 contacts the steel wire 9, the overlapping point of the steel wire 9 moves to the position of the first fixed disk 6 or the second fixed disk 7. At this time, the movable disk 10 contacts the steel wire 9 first and then moves away from the steel wire 9 to force the overlapping point of the steel wire 9 to oscillate on the first fixed disk 6 or the second fixed disk 7. Preferably, the plurality of steel wires 9 have a plurality of overlapping points in the axial direction of the hollow tube 2. By setting the positions of the first fixed disk 6 and the second fixed disk 7, the two can correspond to the two overlapping points of the steel wire 9 respectively, so that when the movable disk 10 reciprocates along the hollow tube 2, the two overlapping points of the steel wire 9 are driven to oscillate on the first fixed disk 6 and the second fixed disk 7 respectively.

[0035] Preferably, the frame 1 is provided with a driving assembly for driving the movable disk 10 to slide back and forth along the hollow tube 2. Specifically, the driving assembly can use a cylinder structure in the prior art to drive the movable disk 10 to move back and forth along the slide slot 11 through the expansion and contraction of the cylinder. Optionally, the driving assembly includes a driving motor 12 fixed to the frame 1 and a driving disk 13 fixed to the output end of the driving motor 12. A driving rod 14 is hinged to the side of the driving disk 13 that deviates from the central axis, and the end of the driving rod 14 is hinged to the movable disk 10. The driving motor 12 and the driving disk 13 are located between the movable disk 10 and the second fixed disk 7, and the driving rod 14 is located between the driving disk 13 and the movable disk 10, one end of which is hinged to the driving disk 13, and the other end is hinged to the movable disk 10. When the driving motor 12 drives the driving disk 13 to rotate, the hinge point of the driving disk 13 and the driving rod 14 reciprocates towards or away from the movable disk 10, thereby driving the movable disk 10 to reciprocate along the slide groove 11 through the driving rod 14. Move closer to or away from the first fixed disk 6, so that the movable disk 10 can be driven to move back and forth along the hollow tube 2 when the driving motor 12 is running, thereby adapting to the weaving of the mesh to drive the steel wire 9 to oscillate, and trying to avoid the phenomenon of wire overlap in the mesh.

[0036] In another embodiment provided by the present invention, further, the frame 1 is rotatably connected with a tension wheel 16 and two conveying wheels 15 for conveying the steel wire 9, the conveying wheel 15 and the tension wheel 16 are respectively located on opposite sides of the steel wire 9, and the frame 1 is provided with a clamping assembly for forcing the tension wheel 16 to contact the steel wire 9. Specifically, in the above embodiment, during the weaving of the mesh, the tension of the plurality of steel wires 9 generally remains unchanged, but due to the presence of the movable disk 10 and other factors, the tension of the plurality of steel wires 9 will still fluctuate. In order to avoid the change in tension affecting the weaving of the mesh as much as possible, a conveying wheel 15 and a tension wheel 16 are provided on the conveying path of the steel wire 9, such as Figure 4 FIG. 1 is a schematic diagram of conveying the steel wire 9. In the conveying direction of the steel wire 9, the conveying wheel 15 and the tension wheel 16 are both located upstream of the spindle 8, and the conveying wheel 15 and the tension wheel 16 are both arranged on the frame 1 ( Figure 1The tension wheel 16 is an extension of the frame 1, wherein the two conveying wheels 15 are located below the steel wire 9, and the tension wheel is located above the steel wire 9; the clamping assembly can use a spring structure or a counterweight structure in the prior art, and optionally, the clamping assembly includes a movable block 17 that is slidably connected to the frame 1 and rotatably connected to the tension wheel 16, and an elastic member 18 is provided between the movable block 17 and the frame 1. The frame 1 is constructed with a movable groove 19, which is located on the side of the corresponding steel wire 9 close to the conveying wheel 15, and the movable groove 19 is perpendicular to the conveying direction of the corresponding steel wire 9, and the movable block 17 is slidably connected in the movable groove 19; the elastic member 18 can use a spring structure in the prior art, one end of which is fixed to the bottom end of the movable block 17, and the other end is fixed to the frame 1, so as to force the movable block 17 and the tension wheel to move downward and contact the steel wire 9 through the elastic member 18. The advantage of such a configuration is that, during the conveying process of the steel wire 9, its tension may float due to the movable disk 10 or other reasons. For this reason, a tightening component is provided to compensate for the tension of the steel wire 9, so as to avoid the looseness of the steel wire 9 during the weaving process of the mesh sleeve, which may easily lead to the overlapping of the mesh sleeve; when the tension of the steel wire 9 is relatively small, the steel wire 9 is relatively loose as a whole. At this time, the movable block 17 can be pulled by the elastic member 18 to drive the tensioning wheel to descend and resist the steel wire 9, thereby increasing the tension of the steel wire 9; on the contrary, when the tension of the steel wire 9 is large, it can overcome the elastic force of the elastic member 18 and make the steel wire 9 between the two conveying wheels 15 be in a state close to a straight line (such as Figure 4 Such arrangement can compensate for the tension of the steel wire 9 and avoid the phenomenon of overlapping wires between the steel wire 9 and the mesh woven therefrom as much as possible.

[0037] As a replacement or parallel solution of the elastic member 18, preferably, the movable block 17 uses a counterweight block, which is set with a certain weight according to the performance of the steel wire 9. The advantage of such a setting is that in the prior art, the spring will experience elastic fatigue after long-term use, that is, the elastic force of the spring cannot be maintained, and the elastic force will decrease after a long period of use. Therefore, it is practical to set the movable block 17 as a counterweight block to replace or cooperate with the elastic member 18, so as to compensate for the tension of the steel wire 9 by gravity instead of elastic force or in cooperation with elastic force, and to improve the weaving quality of the mesh as much as possible.

[0038] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
