The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model embodiment provides a switch cover mechanism on a folding machine, such as Figure 1-5 As shown, the switch cover mechanism on the folding machine includes: a fixed plate 1; a rotating shaft 2 rotatably mounted on the fixed plate 1; a mounting plate 3 fixed on the top of the rotating shaft 2; a first electric telescopic rod 4 arranged on the mounting plate 3, and a supporting ring 5 is installed on the first electric telescopic rod 4; a second electric telescopic rod 6 installed on the supporting ring 5, and a clamping block 7 for clamping the protective cover of the airbag protective shell is fixed on the output rod of the second electric telescopic rod 6; and a driving component arranged on the fixed plate 1 for rotating the rotating shaft 2.

[0025] In this embodiment, the fixed plate 1 serves as the foundation and support of the entire mechanism, ensuring that the mechanism is stable and can be fixed in an appropriate position. The rotating shaft 2 can realize a rotating motion, thereby driving the mounting plate 3 and the components thereon to rotate to adapt to the position transfer of the top cover of the storage tank. The first electric telescopic rod 4 is used to adjust the position of the support ring 5 and the clamping block 7 thereon so that it can accurately align and clamp the airbag protective shell protective cover. The second electric telescopic rod 6 is used to clamp and release the airbag protective shell protective cover. The clamping block 7 is used to clamp the airbag protective shell protective cover, and its design should ensure that it can firmly clamp the top cover and will not cause damage to the top cover when released. The driving assembly is used to drive the rotation of the rotating shaft 2, thereby adjusting the position of the mounting plate 3 and the components thereon to adapt to different positions of the storage tank.

[0026] In a further preferred embodiment of the utility model, the driving assembly includes: a gear 8 fixed on the rotating shaft 2; a rack 9 slidably mounted on the top of the fixed plate 1, the rack 9 meshing with the gear 8; a third electric telescopic rod 10 fixed on the top of the fixed plate 1, and the output rod of the third electric telescopic rod 10 is fixedly connected to the rack 9.

[0027] In this embodiment, the gear 8 is a key component for power transmission, and its design enables it to achieve precise meshing with the rack 9, thereby ensuring that the rotating shaft 2 can rotate smoothly and accurately. The sliding action of the rack 9 will drive the gear 8 meshing with it to rotate, thereby causing the rotating shaft 2 and the components mounted thereon (such as the mounting plate 3, the first electric telescopic rod 4, etc.) to rotate. Through the telescopic action of the third electric telescopic rod 10, the rack 9 can be driven to slide on the fixed plate 1, and then the rotating shaft 2 is driven to rotate through the gear 8. This design enables the rotation angle and speed of the rotating shaft 2 to be precisely controlled by controlling the third electric telescopic rod 10.

[0029] In this embodiment, the support rod 11 serves as a bridge connecting the mounting plate 3 and the slider 12. The support rod 11 ensures that the mounting plate 3 can remain stable during rotation and reduces the shaking caused by rotation. The slider 12 and the slide groove 16 are used in conjunction to limit the rotation trajectory of the mounting plate 3 and ensure that it does not deviate from the predetermined path during rotation. The shape and size of the slide groove 16 match the slider 12 to ensure that the two can slide smoothly together.

[0030] In a further preferred embodiment of the utility model, pressure sensors 20 are installed in the plurality of clamping blocks 7, rubber tubes 19 are sleeved outside the plurality of pressure sensors 20, anti-slip pads 15 are installed on the plurality of rubber tubes 19, and the plurality of anti-slip pads 15 are in contact with the inner walls of the plurality of clamping blocks 7 respectively.

[0031] In this embodiment, the pressure sensor 20 is used to detect the clamping force of the clamp block 7 on the protective cover of the airbag protective shell. The pressure sensor 20 can feed back the clamping force data to the control system in real time to ensure that the clamping force is moderate and not too tight or too loose. The anti-slip pad 15 can increase the friction between the clamp block 7 and the protective cover.

[0032] In a further preferred embodiment of the utility model, a plurality of cylinders 13 are installed at the bottom of the fixed plate 1, and the same base 14 is fixed to the output rods of the plurality of cylinders 13, and both sides of the base 14 are clamped with a clamping plate 17 installed on the folding machine.

[0033] In this embodiment, the cylinder 13 is used as a power source to adjust the height and position of the entire switch cover mechanism.

The clamping plate 17 can fix and position the mechanism and improve the stability and safety of the operation.

[0034] In a further preferred embodiment of the present invention, a baffle 18 is fixed on the top of the fixed plate 1 , and the baffle 18 is L-shaped. The baffle 18 is located directly above the gear 8 and the rack 9 .

[0035] In this embodiment, the baffle 18 can effectively prevent dust, debris or other external factors from entering the meshing area of ​​the gear 8 and the rack 9 during the operation of the mechanism, thereby affecting its normal operation, and at the same time prevent people from touching the gear 8 and the rack 9 and getting injured.

[0036] In a further preferred embodiment of the present invention, the baffle 18 is made of transparent plastic material, and a plurality of the clamping plates 17 are threadedly mounted with fixing bolts that can be threadedly connected to the base 14 .

[0037] In this embodiment, since the baffle 18 is transparent, the operator can easily observe the meshing condition of the gear 8 and the rack 9, so as to promptly discover and deal with possible problems, reduce unnecessary disassembly and maintenance work, and reduce maintenance costs. By tightening the fixing bolts, the base 14 can be firmly fixed between the clamping plates 17.

[0038] In a further preferred embodiment of the present invention, the plurality of anti-slip pads 15 are all made of rubber, and the bottom of the base 14 is inlaid with a plurality of balls, and the plurality of balls can contact the outer wall of the folding machine.

[0039] In this embodiment, the rubber material provides an excellent friction coefficient, which helps to enhance the friction between the clamp block 7 and the airbag protective cover, thereby ensuring the stability of the clamping. The rubber material is wear-resistant and corrosion-resistant, and can maintain its anti-slip performance for a long time, thereby extending the service life of the anti-slip pad 15. The ball bearing makes the entire switch cover mechanism smoother when moving.

[0040] In summary, compared with the related art, the present device can adjust the angle of the rotating shaft 2 by setting the third electric telescopic rod 10 in cooperation with the gear 8 and the rack 9, so as to adjust the angle of the support ring 5 and realize the transfer of the protective cover. The protective cover can be clamped by setting the second electric telescopic rod 6 in cooperation with the clamping block 7 to facilitate the subsequent transfer of the protective cover. The clamping force can be monitored by setting the pressure sensor 20 to prevent the clamping stability from being affected by being too loose or too tight. The height of the clamped protective cover can be adjusted by setting the cylinder 13 to facilitate the transfer of the protective cover.
