DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will further describe the present application in combination with specific embodiments.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0030] like Figure 1 As shown, a vibration-damping structure for a combing machine tensioning mechanism includes: a tensioning plate 1 and at least one movable frame 7 slidably connected to the tensioning plate 1; a tensioning wheel 10 rotatably connected to the movable frame 7; a slider 3 slidably connected to a groove in the tensioning plate 1, the slider 3 having two sliders symmetrically arranged in the groove of the tensioning plate 1; support plates 11 symmetrically arranged at both ends of the movable frame 7, one end of the support plate 11 rotatably connected to the movable frame 7, the other end of the support plate 11 rotatably connected to the slider 3, the support plate 11 and the tensioning plate 1 forming an isosceles triangle for supporting the movable frame 7; and a driving component for driving the two sliders 3 to move towards and away from each other along the groove, thereby driving the movable frame 7 and the tensioning wheel 10 away from and towards the tensioning plate 1 through the isosceles triangle to adjust the tension of the belt 19.

[0031] The above technical solution can improve the shock absorption performance of the tensioning mechanism. In use, by activating the drive component, it can drive the two sliders 3 to move towards and away from each other along the slide groove. The two sliders 3 drive the movable frame 7 to move relative to the tensioning plate 1 through the support plate 11, thereby causing the tensioning plate 1 to move the tensioning wheel 10 away from and towards the tensioning plate 1, thereby adjusting the tension of the belt 19. Specifically, when the tensioning wheel 10 moves away from the tensioning plate 1, the tensioning wheel 10 can increase the tension on the belt 19. Conversely, when the tensioning wheel 10 moves towards the tensioning plate 1, the tensioning wheel 10 can decrease the tension on the belt 19, thereby adjusting the tension of the belt 19 as needed.

[0032] Since the movable frame 7 is in sliding connection with the tensioning plate 1, and each movable frame 7 is driven by two groups of sliding blocks 3 and support plates 11, the support plate 11 and the tensioning plate 1 can form an isosceles triangle frame for supporting the movable frame 7, the triangular structure is more stable, and the anti-vibration effect is better. In theory, only one group of sliding blocks 3 and support plates 11 can also drive the movable frame 7 and the tensioning wheel 10 to move. The purpose of setting two groups is that when one group of sliding blocks 3 and support plates 11 is damaged due to vibration, for example, one group of support plates 11 is broken, or the connection between the support plate 11 and the sliding block 3 is accidentally disconnected due to vibration, the other group of sliding blocks 3 and support plates 11 can still cooperate with the driving component to maintain the driving of the movable frame 7 and the tensioning wheel 10. Therefore, immediate shutdown and maintenance are not required, and thus the safety function is achieved.

[0033] As shown in Figure 2 and Figure 3 In the present embodiment, the movable frame 7 is provided with a fixed block 8 provided with a guide groove 9, and the tensioning plate 1 is provided with a guide rod 6 in sliding cooperation with the guide groove 9. The guide rod 6 cooperates with the guide groove 9 to guide the linear movement of the movable frame 7 along the tensioning plate 1.

[0034] The above technical solution can connect the movable frame 7 and the tensioning plate 1 in a sliding manner.

[0035] As shown in Figure 2 In the present embodiment, the driving component includes a bidirectional screw rod 2 rotatably arranged in a sliding groove of the tensioning plate 1, the bidirectional screw rod 2 cooperates with a screw rod groove 4 arranged in the sliding block 3; a servo motor 5 with an output shaft penetrating through the tensioning plate 1 and extending into the sliding groove is in transmission connection with the bidirectional screw rod 2. The bidirectional screw rod 2 can be rotated in a first direction and a second direction by the servo motor 5, thereby driving the two sliding blocks 3 to move towards each other and away from each other along the sliding groove.

[0036] The above technical solution can drive the two sliding blocks 3 to move towards each other and away from each other along the sliding groove. During use, the servo motor 5 is started to drive the bidirectional screw rod 2 to rotate in the first direction, the bidirectional screw rod 2 drives the two sliding blocks 3 to move towards each other along the sliding groove, the sliding blocks 3 drive the movable frame 7 to rise through the support plates 11, the tensioning wheel 10 connected with the movable frame 7 is driven to rise, and the tensioning wheel 10 increases the tension of the belt 19. Conversely, when it is necessary to reduce the tension, the servo motor 5 is started to drive the bidirectional screw rod 2 to rotate in the second direction opposite to the first direction, the bidirectional screw rod 2 drives the two sliding blocks 3 to move away from each other along the sliding groove, the sliding blocks 3 drive the movable frame 7 to descend through the support plates 11, the tensioning wheel 10 connected with the movable frame 7 is driven to descend, and the tensioning wheel 10 reduces the tension of the belt 19.

[0037] As shown in Figure 1 and Figure 2As shown, in this embodiment, the movable frame 7 and the slider 3 are provided with hinge seats 20 at corresponding positions, and the support plate 11 is movably connected to the movable frame 7 and the slider 3 respectively through the hinge seats 20.

[0038] The above technical solution enables the support plate 11 to be movably connected to the movable frame 7 and the slider 3 via the hinge seat 20.

[0039] like Figure 2 As shown, in this embodiment, each movable frame 7 is provided with two tensioning wheels 10, and a limiting space is formed between the two tensioning wheels 10 to restrict the movement of the belt 19 along the axial and radial directions of the tensioning wheels 10;

[0040] The above technical solution can better limit the belt 19, prevent the belt 19 from disengaging from the tensioner 10 due to vibration, and ensure that the belt 19 is always on the tensioner 10.

[0041] like Figure 3 and Figure 4 As shown, in this embodiment, the vibration damping structure further includes: a movable block 13 rotatably connected to any one of the tensioning wheels 10 in the same movable frame 7; the movable block 13 is slidably connected to the movable groove 12 opened in the movable frame 7; by sliding the movable block 13, it can drive one of the tensioning wheels 10 to move relative to the other tensioning wheel 10, thereby adjusting the size of the limiting space; the movable block 13 has a positioning hole 14 at one end; the movable frame 7 has multiple threaded grooves 15 on its surface that cooperate with the positioning hole 14; and a bolt 16 threadedly connected to the threaded groove 15; by inserting one end of the bolt 16 into the positioning hole 14, the movement of the movable block 13 relative to the movable frame 7 is restricted.

[0042] The above technical solution allows for adjustment of the spacing between two tensioning wheels 10 on the same movable frame 7, thus accommodating belts 19 of different specifications. In use, the bolt 16 is rotated to disengage it from the positioning hole 14 and the threaded groove 15, thereby releasing the sliding restriction on the movable block 13. After sliding the movable block 13 to the designated position, ensure that the positioning hole 14 of the movable block 13 and the threaded groove 15 on the surface of the movable frame 7 are aligned. Tighten the bolt 16 so that it passes through both the positioning hole 14 and the threaded groove 15, thereby completing the adjustment of the spacing between the tensioning wheels 10.

[0043] like Figure 4 As shown, in this embodiment, the bolt 16 is provided with a washer 17 that is adapted to it;

[0044] The above technical solution can reduce the wear between the bolt 16 and the surface of the movable frame 7, and improve the service life of the components.

[0045] like Figure 1As shown, in the embodiment, the two movable racks 7 are symmetrically arranged on the tension plate 1, and the tension plate 1 is provided with a support 18 on one side;

[0046] The above technical scheme can adjust the tension of the belt 19 in a larger range, and the tension plate 1 can be installed on the mounting surface through the support 18.

[0047] Working principle: when in use, the servo motor 5 is started to drive the bidirectional screw rod 2 to rotate in the first direction, the bidirectional screw rod 2 drives the two sliding blocks 3 to move towards each other along the sliding groove, the sliding blocks 3 drive the movable rack 7 to rise through the supporting plate 11, drive the tension pulley 10 connected with the movable rack 7 to rise, the tension pulley 10 increases the tension of the belt 19, on the contrary, when it is needed to reduce the tension, the servo motor 5 is started to drive the bidirectional screw rod 2 to rotate in the second direction opposite to the first direction, the bidirectional screw rod 2 drives the two sliding blocks 3 to move away from each other along the sliding groove, the sliding blocks 3 drive the movable rack 7 to descend through the supporting plate 11, drive the tension pulley 10 connected with the movable rack 7 to descend, the tension pulley 10 reduces the tension of the belt 19;

[0048] When it is needed to adjust the distance between the two tension pulleys 10 on the movable rack 7, so as to adapt to different specifications of the belt 19, the bolt 16 is rotated to be separated from the positioning hole 14 and the threaded groove 15, so as to release the sliding restriction on the movable block 13, after the movable block 13 is slid to the specified position, the positioning hole 14 of the movable block 13 is ensured to be aligned with the threaded groove 15 on the surface of the movable rack 7, and the bolt 16 is screwed to penetrate through the positioning hole 14 and the threaded groove 15 at the same time, so as to complete the adjustment of the distance between the tension pulleys 10.
