Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic glass production equipment, in particular to a natural gas gun. Background Art

[0002] In the photovoltaic glass production process, the molten glass passes through the overflow of the melting furnace and is rolled into a flat embossed glass sheet by a calendering roller. The edge of the overflow of the melting furnace is composed of retaining bricks. The temperature of the glass liquid on both sides is lower than that of the glass liquid in the middle. Therefore, there is a lateral temperature difference in the glass liquid at the overflow, which causes the glass liquid to be uneven and reduces the performance of the glass. Adding natural gas guns on both sides of the overflow is the most effective measure to reduce the lateral temperature difference of the glass liquid. By directly blowing and burning the edge glass liquid, the temperature of the glass liquid on both sides is increased to reduce the lateral temperature difference of the entire glass liquid and improve the forming performance of the glass liquid. At present, the traditional natural gas gun devices for photovoltaic glass are basically fixed, and their positions cannot be adjusted. Before producing glass of different specifications, the position of the natural gas gun needs to be repeatedly adjusted and calibrated, which is troublesome to operate. Utility Model Content

[0003] The utility model provides a natural gas gun to solve the technical problem that the position of the natural gas gun cannot be adjusted.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A natural gas gun comprises an air gun body, a first mounting seat, a second mounting seat, a vertical lifting device and a fixing frame, wherein the air gun body is assembled on the first mounting seat by rotating around a second rotating shaft extending horizontally so as to adjust the spray angle of the air gun body in the vertical direction; the second mounting seat is arranged below the first mounting seat, and the first mounting seat is rotatably assembled with the second mounting seat by a first rotating shaft extending vertically; the fixing frame is used for fixed installation on a workbench, the vertical lifting device is arranged between the second mounting seat and the fixing frame, and the vertical lifting device is used to adjust the height of the air gun body in the vertical direction.

[0006] The beneficial effects are: the air gun body can be rotated up and down to adjust its tilt angle in the vertical direction, and can also be rotated in the horizontal direction to adjust the direction, the vertical lifting device can adjust the height of the air gun body, and the position of the natural gas gun can be adjusted.

[0007] Furthermore, a connecting rod is fixed on the air gun body, and the rotating shaft 2 is arranged on the top surface of the mounting seat. The connecting rod is rotatably connected to the rotating shaft 2. A driving mechanism 1 is provided on the mounting seat, and the driving mechanism 1 includes a rotating shaft 3 extending up and down, a worm wheel 1 fixed on the rotating shaft 3 and coaxially arranged with the rotating shaft 2, a worm screw 1 meshing with the worm wheel 1, and a lifting rod threadedly connected to the rotating shaft 3. The rotating shaft 3 and the worm screw 1 are both rotatably connected in the mounting seat, and the worm screw 1 is perpendicular to the rotating shaft 3. The rotation of the worm screw 1 is used to drive the worm wheel 1 and the rotating shaft 3 to rotate synchronously. The rotation of the rotating shaft 3 is used to drive the lifting rod to move up and down. The top end surface of the lifting rod is in pressure contact with the connecting rod, and the up and down movement of the lifting rod is used to drive the connecting rod to rotate up and down around the rotating shaft 2.

[0008] The beneficial effect is: by twisting the worm gear one, the lifting rod can be driven to move up and down, and the upward movement of the lifting rod can press the connecting rod to drive the air gun body to rotate upward. When the lifting rod moves downward, the connecting rod moves downward under the action of gravity to make the air gun body rotate downward. Due to the self-locking characteristics of the worm gear (when the helix angle of the worm gear is smaller than the friction angle between the meshing gear teeth, the worm gear mechanism has self-locking properties, that is, the worm gear can only drive the worm wheel to rotate, and the worm wheel cannot drive the worm gear in reverse), when the worm gear one rotates to drive the lifting rod up and down to a certain position, when no other force acts on the worm gear one, the position of the lifting rod is fixed, the inclination angle of the air gun body in the vertical direction is fixed, and the use stability is strong.

[0009] Furthermore, the lifting rod is rotatably connected to an arc plate, the axis around which the arc plate rotates is perpendicular to the lifting rod and the connecting rod, a plurality of bull's eye bearings are fixed on the inner concave surface of the arc plate, and the connecting rod is in contact with the balls of the bull's eye bearings.

[0010] The beneficial effects are: the bull's eye bearing is in contact with the connecting rod, the friction force is small, the force required to screw the worm is reduced, and the height of the lifting rod is easy to adjust.

[0011] Furthermore, the rotating shaft 1 is rotatably connected in the mounting seat 2, the top surface of the rotating shaft 1 is vertically fixedly connected to the bottom surface of the mounting seat 1, and the mounting seat 2 is provided with a driving mechanism 2 for driving the mounting seat 1 to rotate horizontally. The driving mechanism 2 includes a worm wheel 2 fixed on the rotating shaft 1 and arranged coaxially with the rotating shaft, and a worm gear 2 meshing with the worm wheel 2, and the worm gear 2 is perpendicular to the rotating shaft 1.

[0012] The beneficial effect is that by turning the worm gear 2, the rotating shaft 2 can be driven to rotate, thereby adjusting the rotation angle of the mounting seat 1 in the horizontal direction. Due to the self-locking characteristics of the worm gear, when no other force acts on the worm gear 2, the position of the mounting seat 2 is fixed, the horizontal direction of the air gun body is fixed, and the stability of use is strong.

[0013] Furthermore, handles are fixedly provided on both sides of the worm gear 1 and the worm gear 2.

[0014] The beneficial effect is that the setting of the handle can increase the torque when the worm gear 1 and the worm gear 2 are screwed, and reduce the force required for screwing.

[0015] Furthermore, the vertical lifting device is a scissors-type lift.

[0016] The beneficial effects are: the lifting process of the scissor lift is smooth, the space utilization rate is high, the space occupied by the device is reduced, and the stability of use is good.

[0017] Furthermore, the fixing frame is composed of a top plate, a bottom plate, and a connecting plate 1 vertically fixed between the top plate and the bottom plate; the vertical lifting device is located between the top plate and the mounting seat 2; the workbench is located between the top plate and the bottom plate; the bottom plate is vertically threaded with bolts, and the bolts are rotated upward to press the bottom surface of the workbench, so that the fixing frame is fixedly installed on the workbench.

[0018] The beneficial effect is that the fixing frame can be fixedly installed on the workbench by screwing the bolts, the installation is simple, and the position of the device can be adjusted conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

Figure 1 As shown, a connecting rod 3 is fixed on the air gun body 1, and a rotating shaft 2 4 extending horizontally and perpendicular to the extending direction of the air gun body 1 is fixed on the top surface of the mounting seat 2. The two end surfaces of the rotating shaft 2 4 are fixedly connected to the top surface of the mounting seat 2 through vertical plates 5. A circular hole coaxial with the rotating shaft 2 4 is provided on the connecting rod 3, and the rotating shaft 2 4 is inserted into the circular hole so that the connecting rod 3 is rotatably connected to the rotating shaft 2 4.

[0029] The mounting seat 2 is provided with a driving mechanism 1 for driving the air gun body 1 to rotate up and down around the rotating shaft 24. Figure 2 As shown, the driving mechanism 1 includes a rotating shaft 3 6 extending up and down, a worm wheel 7 fixed on the rotating shaft 3 6 and coaxially arranged with the rotating shaft 3 6, a worm 8 meshing with the worm wheel 7, and a lifting rod 9 threadedly connected to the rotating shaft 3 6. The rotating shaft 2 4 and the worm 8 are rotatably connected in the mounting seat 2 through a rotating bearing. The worm 8 is perpendicular to the rotating shaft 3 6. Handles 10 are fixedly installed at both ends of the worm 8. The handles 10 are rotated to drive the worm 8 to rotate. The worm 8 rotates to drive the worm wheel 7 and the rotating shaft 3 6 to rotate synchronously around the axis of the rotating shaft 3 6. The lifting rod 9 is sleeved outside the rotating shaft 3 6 and is threadedly connected with the rotating shaft 3 6. The lifting rod 9 is located above the worm gear 1 7. The lifting rod 9 is provided with ridges 11 on both sides. The mounting seat 1 2 is provided with a through hole for the lifting rod 9 to move up and down and a slide groove 12 for the ridges 11 to move up and down. The ridges 11 and the slide groove 12 cooperate with each other so that the lifting rod 9 and the rotating shaft 3 6 will not rotate synchronously. The rotating shaft 3 6 rotates to drive the lifting rod 9 to move up and down. The top surface of the lifting rod 9 is in pressure contact with the connecting rod 3. The lifting rod 9 moves up and down, which can drive the air gun body 1 to rotate up and down around the rotating shaft 2 4 to adjust the inclination angle of the air gun body 1 in the vertical direction.

[0030] The mounting seat 12 is rotatably connected to the mounting seat 2 14 located below the mounting seat 12 through a rotating shaft 13 extending up and down. The rotating shaft 13 is rotatably connected in the mounting seat 2 14 through a rotating bearing. The top surface of the rotating shaft 13 is vertically fixedly connected to the bottom surface of the mounting seat 12. The mounting seat 2 14 is provided with a driving mechanism 2 for driving the mounting seat 2 to rotate horizontally. Figure 3 As shown, the driving mechanism 2 includes a worm gear 2 15 fixed on the rotating shaft 13 and coaxially arranged with the rotating shaft 13, and a worm 2 16 meshing with the worm gear 2 15. The worm 2 16 is rotatably connected in the mounting seat 2 14 through a rotating bearing. The worm 2 16 is perpendicular to the rotating shaft 13. Handles 10 are fixedly installed at both ends of the worm 2 16. By turning the handle 10, the worm 2 16 is driven to rotate to drive the rotating shaft 13 to rotate around its own axis, thereby driving the mounting seat 2 to rotate horizontally.

[0031] The fixing frame 17 is composed of a top plate 18, a bottom plate 19, and a connecting plate 20 vertically fixed between the top plate 18 and the bottom plate 19. The vertical lifting device 21 is a scissor lift, preferably a hand-cranked scissor lift, and the vertical lifting device 21 is installed between the top plate 18 and the mounting seat 14 by means of bolts 22 and the like. The fixing frame 17 is installed on the workbench, and the side plate of the workbench is located between the top plate 18 and the bottom plate 19. The bottom plate 19 is vertically threaded with bolts 22, and the bolts 22 are rotated upward to press the bottom surface of the workbench, so that the fixing frame 17 is fixedly installed on the workbench.

[0032] The method of using the device is as follows: adjust the position of the fixing frame 17, tighten the bolt 22, fix the fixing frame 17 on the workbench, adjust the height of the vertical lifting device 21, adjust the height of the air gun body 1 in the vertical direction to a suitable position, turn the handle 10 on the side of the worm gear 16, and adjust the horizontal direction of the air gun body 1; turn the handle 10 on the side of the worm gear 8 to adjust the inclination angle of the air gun body 1 in the vertical direction. Due to the self-locking characteristics of the worm gear, when no other external force is applied to the worm gear 8 and the worm gear 16, the air gun body 1 remains in a stable and static state, which is easy to adjust and has strong stability in use.

[0033] Embodiment 2

[0034] like Figure 4-Figure 5The second embodiment of the utility model is shown. The difference between this embodiment and the first embodiment is that two lugs 23 are vertically fixed on the top surface of the lifting rod 9. The two lugs 23 are rotatably connected by a rotating bearing and are perpendicular to the lifting rod 9 and the rotating shaft 24 of the connecting rod 3. The rotating shaft 24 is fixedly connected to the arc plate 25 through the connecting plate 26. A plurality of bull's eye bearings 27 are fixed on the inner concave surface of the arc plate 25. The outer peripheral surface of the connecting rod 3 contacts the balls of the bull's eye bearings 27. When the lifting rod 9 moves up and down, the arc plate 25 rotates as needed, and the connecting rod 3 slides in the arc plate 25. Due to the action of the bull's eye bearings 27, the friction between the connecting rod 3 and the arc plate 25 is reduced, and the force required to drive the worm 8 to rotate is small, which is more convenient to use.

[0035] Embodiment 3
