[0024] Please refer to Figure 1-2As shown in the figure, the utility model relates to a strip forming machine for a fireproof rolling shutter door, which includes a feeding device for feeding a steel strip coil used as a production raw material. The feeding device includes a bottom plate 10, a side plate 1 is arranged on the upper surface of the bottom plate 10, and a steel strip supporting frame 12 is rotatably installed on one side of the side plate 1. During use, the steel strip supporting frame 12 is driven by a motor to rotate, thereby driving the steel strip coil 100 arranged thereon to rotate. At the same time, in order to avoid the overall relaxation of the steel strip coil 100 during use, an L-shaped frame 11 is arranged on the top of the side plate 1. A telescopic cylinder 13 is installed on the top of the L-shaped frame 11 in a vertically telescopic manner. The output end of the telescopic cylinder 13 is connected with a mounting plate 14.

[0025] In order to enable the extrusion mechanism composed of the elastic telescopic member 15 and the extrusion wheel 151 to extrude the steel strip coil 100 and avoid the relaxation of the steel strip coil 100, the provided elastic telescopic member 15 includes a mutually cooperating inner sleeve A and outer sleeve A, and a spring A is connected between the inner sleeve A and the outer sleeve A.

[0026] Combined with the design requirements of this application, in order to facilitate controlling the extrusion mechanism to achieve the same extrusion effect on the steel strip coil 100 with a continuously decreasing diameter during use, during use, while the diameter of the steel strip coil 100 is continuously decreasing, the telescopic cylinder 13 of the extrusion mechanism is controlled to extend synchronously.

[0027] In order to realize the synchronous extension control of the telescopic cylinder 13, it further includes a distance detection mechanism for detecting the distance between the bottom end of the steel strip coil 100 and the upper surface of the bottom plate 10. The distance detection mechanism is connected to a controller, and at the same time the controller is connected to the telescopic cylinder 13. The distance detection mechanism can detect the distance between the bottom end of the steel strip coil 100 and the upper surface of the bottom plate 10, so as to identify the diameter of the steel strip coil 100.

[0028] It can be known that in a possible implementation manner, the distance detection mechanism includes an infrared distance sensor A arranged on the upper surface of the bottom plate 10.

[0029] It can be known that in another possible implementation manner, as Figure 1-2, a rectangular opening 16 is vertically arranged on the side plate 1. A rodless cylinder 161 is vertically arranged in the rectangular opening 16. A slider 162 is cooperatively arranged on the rodless cylinder 161. A convex block 163 is arranged on one side of the slider 162. A groove is arranged on the upper surface of the convex block 163, and a movable column 164 is connected in the groove through a spring B. The end of the movable column 164 is set as a spherical structure, and a contact sensor is arranged on the spherical structure; the distance detection mechanism includes an infrared distance sensor B arranged on the upper surface of the bottom plate 10, that is, when in use, while the diameter of the steel strip coil 100 is continuously decreasing, the slider 162 is controlled to move along the axial direction of the rodless cylinder 161, and the contact sensor is controlled to always contact the steel strip coil 100. At this time, the distance between the slider 162 and the upper surface of the bottom plate 10 is detected by the infrared distance sensor B. Furthermore, on the premise that the central height of the steel strip coil 100 is certain, the distance between the bottom end of the steel strip coil 100 and the upper surface of the bottom plate 10 can be obtained, so as to identify the diameter of the steel strip coil 100.

[0030] It can be known that in other possible implementation manners, such as Figure 3-4 , a rectangular opening 16 is vertically arranged on the side plate 1. A telescopic member 17 that telescopically moves in the vertical direction is installed on one side wall at the top of the rectangular opening 16. The end of the telescopic member 17 is connected to a rotating shaft 18 that protrudes from one side of the rectangular opening 16. A rotating wheel 19 that abuts against the steel strip coil 100 is rotatably connected to the rotating shaft 18; the telescopic member 17 includes an inner sleeve B171 and an outer sleeve B172 that are sleeved with each other. The outer sleeve B172 is fixed at the top of the rectangular opening 16. A spring C173 is connected between the end of the inner sleeve B171 and the bottom surface of the outer sleeve B172; the bottom surface of the inner sleeve B171 is connected to a movable block 175 through a spring D174. A pressure sensor 177 is arranged at the end of the movable block 175. A guide rod 178 inserted into the inner sleeve B171 is connected to the bottom surface of the outer sleeve B172. The end of the guide rod 178 is connected to a top block 176 whose end abuts against the pressure sensor 177 through a spring E179; in this implementation manner, as the diameter of the steel strip coil 100 is continuously decreasing, at this time, under the action of the spring C173, the inner sleeve B171 contracts into the outer sleeve B172, that is, the inner sleeve B171 moves vertically upward, and at the same time, the rotating wheel 19 is always kept in contact with the steel strip coil 100; at the same time, when in use, through the setting of the pressure sensor 177, it is convenient to collect and determine the data of the pressure sensor 177 during use to obtain the length of the telescopic member 17, and further, when in use, it is convenient to determine the diameter of the steel strip coil 100 according to the detected length of the telescopic member 17.
