Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 The utility model provides a technical solution: an angle-adjustable galvanized air duct folding mechanism, comprising two parallelly arranged frames 1, such as Figure 1 and Figure 2As shown, the bottoms of the two racks 1 are connected via a reinforcement frame 18, and the reinforcement frames 18 are connected via a reinforcement seat 17, and support legs 19 are provided at the bottom of the racks 1, and support pads are provided at the bottom of the support legs 19, and the support pads are placed or fixed on the ground.

[0028] like Figure 1 and Figure 2 As shown, the tops of the two frames 1 are connected by a bearing plate 3, and a clamping structure for clamping the galvanized sheet is provided on one side of the top of the bearing plate 3; Figure 1 As shown, the clamping structure includes a mounting seat 11 arranged outside the frame 1, and a first telescopic mechanism 12 and a guide shaft 9 are vertically mounted on the mounting seat 11. The guide shaft 9 and the mounting seat 11 are in a movable relationship, so that the guide shaft 9 can be telescoped in the mounting seat 11, and the first telescopic mechanism 12 and the mounting seat 11 are in a fixed relationship;

[0029] The top of the first telescopic mechanism 12 extends above the top of the frame 1, and an L-shaped connecting frame 5 extending above the carrying plate 3 is installed on the top of each first telescopic mechanism 12, and the top of the guide shaft 9 is connected to the top side of the L-shaped connecting frame 5 through the connecting seat 8, so that the first telescopic mechanism 12 drives the L-shaped connecting frame 5 to move up and down, and the guide shaft 9 can move up and down in the mounting seat 11, playing a role of stable guidance;

[0030] The bottoms of the two L-shaped connecting frames 5 are connected by a support beam 7, on which a plurality of support arms 6 are installed. The support arms 6 extend toward the folding plate 2, and a pressing plate 4 is installed at the bottom of the end of the support arm 6. The edge of the pressing plate 4 is aligned with the edge of the bearing plate 3. In actual use, the galvanized sheet to be bent is placed on the bearing plate 3, and the first telescopic mechanism 12 is controlled to drive the pressing plate 4 to press the galvanized sheet to fix it.

[0031] like Figure 1 As shown, a folding plate 2 is provided on one side of the carrying plate 3 close to the pressing structure, and a gap is provided between the folding plate 2 and the edge of the carrying plate 3, and the gap is used for the movement of the folding plate 2. Support shafts 27 are provided at both ends of the folding plate 2, and the ends of the support shafts 27 are rotatably mounted on the frame 1. A second swing arm 28 is installed at the middle position of the bottom of the folding plate 2, and the top of the second swing arm 28 is rotatably connected to the second telescopic mechanism 21, as shown in FIG. Figure 2 As shown, the other end of the second telescopic mechanism 21 is rotatably mounted on the mounting frame 20. The mounting frame 20 is located below the bearing plate 3 and its two ends are respectively connected to the frame 1. Figure 3 As shown by the middle dotted line, when the second telescopic mechanism 21 is extended, the second telescopic mechanism 21 can drive the second swing arm 28 to move upward, and the second swing arm 28 drives the folding plate 2 to rotate around the support shaft 27. In the initial state, the folding plate 2 is flush with the bearing plate 3. When the folding plate 2 rotates, it can drive the galvanized plate to fold above the bearing plate 3.

[0032] The end of the support shaft 27 is provided with a device for detecting its rotation angle, through which the rotation angle of the support shaft can be adjusted, such as Figure 1 As shown, a mounting plate 14 is provided on one side of the frame 1, the mounting plate 14 is coaxial with the support shaft 27, a first swing arm 13 is coaxially mounted on the end of the support shaft 27, the first swing arm 13 is parallel to the bearing plate 3 and the tops of the two are flush;

[0033] A circular guide rail 10 coaxial with the support shaft 27 is provided on the side of the mounting plate 14. The circular guide rail 10 is an open-loop setting, which is convenient for installing the slider. A matching slider 22 is provided on the circular guide rail 10. The slider 22 is provided with a positioning bolt for modulating it to a preset position. A contact sensor 23 is provided on the side of the slider 22 away from the circular guide rail 10. The position of the contact sensor 23 corresponds to the first swing arm 13. When the first swing arm 13 rotates, it can contact the contact sensor 23, that is, the first swing arm 13 can rotate to the top of the contact sensor 23 and contact it. The contact sensor 23 and the second telescopic mechanism 21 are respectively connected to the controller.

[0034] The contact sensor 23 is adjustable, that is, an adjusting bolt 25 is vertically provided on the side of the slider 22 away from the circular guide rail 10, and an L-shaped bracket 24 is also provided on the side of the slider 22. The L-shaped bracket 24 is penetrated and arranged on the adjusting bolt 25, and a nut for tightening the L-shaped bracket 24 is threaded on the adjusting bolt 25; the contact sensor 23 is installed in the top of the L-shaped bracket 24, and by adjusting the position of the L-shaped bracket 24, the surface of the first swing arm 13 at the top of the contact sensor 23 is made to contact vertically.

[0035] Because when the bending angle of the folding plate 2 is changed, the travel distance between the folding plate 2 and the contact sensor 23 will change, so the position of the contact sensor 23 must be adjusted.

[0036] The specific adjustment process is described below with a bending angle of 90°. Figure 5 As shown, the positioning bolt is loosened and the slider 22 is moved along the circular guide rail 10. When the slider 22 reaches the preset position, the nut on the adjusting bolt 25 is loosened, and then the end of the L-shaped bracket 24 is adjusted to face the first swing arm 13, so that the contact sensor 23 can be vertically contacted with the side of the first swing arm 13. At this time, the first swing arm 13 rotates to 90° and touches the contact sensor 23. After the two are in contact, the first swing arm 13 and the folding plate 2 stop moving; by analogy, when the bending angle requires other angles, the position of the contact sensor 23 can be changed by adjusting the slider 22.

[0037] Furthermore, the first swing arm 13 is detachable, that is, the first swing arm 13 is installed on the side of the mounting plate 26, the middle of the mounting plate 26 is provided with a hole sleeved on the support shaft 27, and the end of the support shaft 27 is threaded with a nut for fastening the mounting plate 26.

[0038] Further, such as Figure 1 As shown, a control cabinet 15 is provided on the side of the frame 1, and a controller is arranged in the control cabinet 15. The controllers are respectively connected to the first telescopic mechanism 12, wherein the first telescopic mechanism 12 and the first telescopic mechanism 12 are one of a hydraulic cylinder or a pneumatic cylinder, and an installation cabinet 16 is installed on the reinforcement seat 17 and the reinforcement frame 18, and a drive station corresponding to the hydraulic cylinder or the pneumatic cylinder is arranged in the installation cabinet 16.

[0039] Finally, when the utility model is in use, the galvanized sheet is placed on the supporting plate 3, one side of the galvanized sheet is extended onto the folding plate 2, and then the second telescopic mechanism 21 is controlled to drive the folding plate 2 to move upward, so that the folding plate 2 bends the galvanized sheet along the edge of the supporting plate 3, and the bending degree is when the first swing arm 13 stops immediately after contacting the sensor 23, and the most important thing is that the position relationship between the first swing arm 13 and the contact sensor 23 can be adjusted by adjusting the position of the contact sensor 23, so as to change the flipping degree of the folding plate 2.

[0040] Based on the above embodiment, it can be further optimized by providing a circularly distributed scale on the surface of the mounting plate 14 outside the circular guide rail 10 and a pointer pointing to the scale on the slider 22, so as to facilitate observation of the adjustment position of the slider 22.
