The front side of the gear plate 22 is fixedly connected with evenly distributed sealing plates 23. The driving mechanism 2 also includes a gear 24 and a driving motor 25. The gears 24 are all rotatably connected to the front side of the automatic diameter-changing platform 1 through a rotating shaft. A fixing frame is provided on the front side of the automatic diameter-changing platform 1. The front side of the fixing frame is provided with a driving motor 25. The input end of the driving motor 25 is electrically connected to the output end of the external single-chip microcomputer. The output shaft of the driving motor 25 is fixedly connected to the front end of the rotating shaft on the upper right side. The gears 24 are all meshedly connected with the gear plate 22. The sealing plate 23 can be a silicone sealing plate, and the sealing plate 23 can also be a bronze sealing plate. After the external pipe or rod is extruded, its own port is connected to the sealing plate 23 at the lowest end of the device. Axially aligned contact, the sealing plate 23 is pressed and fixed on the gear disc 22 by the pressure plate. By manually replacing the sealing plate 23, it can meet the needs of more specifications of products. When the production specifications of pipes or bars change, the model and specifications of the sealing plate 23 need to be changed. At this time, the external single-chip microcomputer starts the driving motor 25, and the driving motor 25 drives the corresponding gear 24 to rotate through the output shaft. The upper gear 24 is connected by meshing so that the gear disc 22 rotates axially around the core shaft 21, so that the sealing plate 23 is automatically replaced with the corresponding sealing installation model and specifications according to the needs. The automatic variable diameter sealing machine with multiple sets of linkage is installed on the production line.

[0025] The clamping mechanism 3 is arranged at the front side of the automatic diameter reducing platform 1. The clamping mechanism 3 includes a clamping cylinder 31 and a pressing head 32. The clamping cylinder 31 is arranged at the front side of the connecting frame. The telescopic end of the clamping cylinder 31 is provided with a pressing head 32. The telescopic end of the clamping cylinder 31 drives the pressing head 32 to move through the control of an external air compressor. The corresponding side end surface of the sealing plate 23 is pressed against the sealing box body by the pressing head 32 to achieve the purpose of sealing the joint surface.

[0026] Position detection mechanism 4: It is arranged on the front side of the driving mechanism 2. The position detection mechanism 4 includes a photoelectric sensor 41 and a limit plate 42. The photoelectric sensor 41 is arranged on an external mounting frame. The photoelectric sensor 41 is bidirectionally electrically connected to the external single-chip computer. The front side of the gear plate 22 is provided with evenly distributed limit plates 42. The photoelectric sensor 41 and the limit plates 42 are installed in coordination. The external single-chip computer starts the photoelectric sensor 41. The photoelectric sensor 41 uses the optical signal through the internal photoelectric sensor element to detect the object passing inside, and transmits the result to the external single-chip computer in the form of an electrical signal. When the model and specification of the sealing plate 22 is converted, the gear plate 22 drives the limit plate 42 to rotate. When the limit plate 42 passes through the inside of the photoelectric sensor 41, the optical signal emitted by the photoelectric sensor 41 changes, thereby transmitting the detection result to the external single-chip computer. The photoelectric sensor 41 determines that the sealing plate 23 of the corresponding model and specification currently required rotates to the corresponding installation position by sensing the limit plate 42 installed at a fixed position, and accurately controls the position conversion of the corresponding sealing plate replaced by the pipe or rod.

[0027] The working principle of the automatic variable diameter sealing machine provided by the utility model is as follows: when using the device, firstly, multiple sets of it are linked and fixed to the designated positions at both ends of the vacuum box, water tank or water tank of the external pipe or rod extrusion production line through bolts, and then the clamping cylinder 31 is connected to the external air compressor. After the external pipe or rod is extruded, its own port is axially aligned and contacted with the sealing plate 23 at the lower end of the device, and then the telescopic end of the clamping cylinder 31 is controlled by the external air compressor to drive the pressure head 32 to move, and the corresponding side end face of the sealing plate 23 is pressed against the sealing box body by the pressure head 32 to achieve the purpose of sealing the joint surface. The sealing plate 23 is fixed on the gear disk 22 by the pressure plate. By manually replacing the sealing plate 23, it can meet the needs of products with more specifications. When the production specifications of the pipe or rod change, the model and specifications of the sealing plate 23 need to be changed. At this time, the external single-chip microcomputer starts the driving motor 25, and the driving motor 25 drives the rotating shaft at the upper end to drive the sealing plate 23 through the output shaft. The corresponding gear 24 rotates, and the upper gear 24 is meshed to make the gear plate 22 rotate axially around the core shaft 21, so that the sealing plate 23 is automatically replaced with the corresponding sealing installation model and specification according to the demand. At the same time, the external single-chip microcomputer starts the photoelectric sensor 41. The photoelectric sensor 41 uses the optical signal through the internal photoelectric sensor element to detect the object passing inside, and transmits the result to the external single-chip microcomputer in the form of an electrical signal. When the model and specification of the sealing plate 22 is converted, the gear plate 22 drives the limit plate 42 to rotate. When the limit plate 42 passes through the inside of the photoelectric sensor 41, the optical signal emitted by the photoelectric sensor 41 changes, thereby transmitting the detection result to the external single-chip microcomputer. The photoelectric sensor 41 determines that the sealing plate 23 of the corresponding model and specification currently required rotates to the corresponding installation position by sensing the limit plate 42 installed in a fixed position. The device can automatically convert the corresponding installation model and specification of the sealing plate according to the production requirements of pipes or bars. It is convenient and quick to use. Figure 1 to Figure 2 The maximum installation specification allowed for the sealing plate 23 is switched to the minimum specification for plate installation.
