DETAILED DESCRIPTION

[0023] like Figures 1 to 7As shown, a transformer corrugated sheet conveying and folding composite machine includes a folding mechanism and a conveying mechanism. The folding mechanism includes a base 1, a fixed-length structure, and an upper mold 2 and a lower mold 3 for folding installed on the base 1. The lower mold 3 is fixed, and the fixed-length structure is located in front of the lower mold 3. The upper mold 2 is pressed down to fold the edge. The conveying mechanism includes two left and right conveying arm mechanisms 4. The two conveying arm mechanisms 4 are both installed on the rear side of the base 1 through the front end structure. The front part of the conveying arm mechanism 4 has a folding correction mechanism. The folding correction mechanism includes a correction lock tongue mechanism and a forward pushing mechanism 7. The correction lock tongue mechanism is moved in the conveying direction through a guide rail mechanism. The correction lock tongue mechanism is slidably arranged, and includes a correction lock tongue 5 and a telescopic driving mechanism 6. The telescopic driving mechanism 6 is used to drive the correction lock tongue 5 to insert into the gap between the corrugated sheets 23. The forward pushing mechanism 7 drives the correction lock tongue mechanism to move forward in the conveying direction. The front side of the upper mold 2 has a spring pressure plate mechanism, and the spring pressure plate mechanism includes a pressure plate 8 and a spring mechanism. The pressure plate 8 is installed on the spring mechanism, and the spring mechanism is arranged on the upper mold 2. When the upper mold 2 presses down on the folding edge, the pressure plate 8 moves with the upper mold 2, and cooperates with the lower mold 3 through its lower mouth to clamp the front end edge of the corrugated sheet 23. The spring mechanism is used to provide clamping force.

[0024] The conveying arm mechanism 4 is slidably mounted on the base 1 through the guide rail mechanism 9, and the conveying arm mechanism 4 is spaced by a screw spacing adjustment mechanism. The screw spacing adjustment mechanism includes a screw 10 mounted on the base 1, two nut seats mounted on the screw 10, and a screw drive adjustment mechanism 11. The screw 10 is a forward and reverse bidirectional screw. The two nut seats are respectively mounted on the forward section and the reverse section of the screw, and the two nut seats are respectively mounted on the two conveying arm mechanisms 4. The screw drive adjustment mechanism 11 drives the two conveying arm mechanisms 4 to move closer or separate by rotating the screw 10 to adjust the spacing. The screw drive adjustment mechanism 11 is specifically a servo motor. The screw spacing adjustment mechanism is controlled by a precision encoder, which can make the spacing adjustment accuracy of the conveying arm mechanism 4 reach 0.1 / 100㎜.

[0025] The specific structure of the conveying arm mechanism 4 is as follows: it includes a slide 4-1, a front driving sprocket device 4-2 and a rear driven sprocket device 4-3, a conveying chain 4-4, a guide bar 4-5 and a folding correction mechanism. The slide 4-1 is the installation base of the conveying arm mechanism 4. The front driving sprocket device 4-2 and the rear driven sprocket device 4-3 are respectively installed at the front and rear ends of the slide 4-1. The conveying chain 4-4 is sleeved on the sprockets of the front driving sprocket device 4-2 and the rear driven sprocket device 4-3, and is used for conveying support and forward conveying the corrugated sheet 23. The guide bar 4-5 is suspended on the slide 4-1 through a pad to guide the forward conveyance of the corrugated sheet 23.

[0026] like Figure 1 and 7As shown, the specific structures of the correction lock tongue mechanism and the forward pushing mechanism 7 of the folding correction mechanism are as follows: the correction lock tongue 5 of the correction lock tongue mechanism is installed in the correction seat 12 for telescopic operation, the telescopic driving mechanism 6 is specifically a cylinder driving mechanism, and the telescopic driving mechanism 6 is installed on the correction seat 12. The cylinder driving mechanism drives the correction lock tongue 5 through the cylinder rod, and the correction seat 12 is installed on the guide rail mechanism 9 for sliding. The forward pushing mechanism 7 is also specifically a cylinder driving mechanism, and the forward pushing mechanism 7 is installed on the conveying arm mechanism 4. The cylinder rod of the forward pushing mechanism 7 is connected to the correction seat 12 for driving the correction lock tongue mechanism.

[0027] The front side surface of the correction lock tongue 5 is a plane, and the rear side surface is an inclined arc surface.

[0028] like Figure 5 and 6 As shown, the specific structure of the spring mechanism of the pressure plate 8 is: it includes a spring 13, an end plate 14 and a guide block 15. The front side of the upper mold 2 has a row of multiple spring mechanisms, and the spring mechanism is installed through the spring hole 16 on the front side of the upper mold 2. The rear side of the spring hole 16 has an open groove, and the guide block 15 has a convex rib. The guide block 15 and the spring 13 are arranged in the spring hole 16. The convex rib of the guide block 15 is embedded in the open groove. The end plate 14 is installed on the top of the upper mold 2 to close the upper end of the spring hole 16. The pressure plate 8 is installed on the convex rib, and the spring 13 is located between the guide block 15 and the end plate 14.

[0029] The specific structure of the folding mechanism is: it includes a base 1 and an upper mold 2 and a lower mold 3 for folding installed on the base 1, the lower mold 3 is installed on the upper plane of the base 1, the two ends of the upper mold 2 are connected to the folding drive cylinder 17, the folding drive cylinder 17 is arranged in the base 1, the cylinder rod of the folding drive cylinder 17 extends out of the upper plane of the base 1 and is connected to the upper mold 2, the base 1 also has a guide rod mechanism and a guide synchronization mechanism, there is a guide rod mechanism at each end of the upper mold 2, the guide rod mechanism includes a guide rod 18 and a guide cylinder 19 matched therewith, the guide cylinder 19 is fixed in the base 1, the upper end of the guide rod 18 extending out of the guide cylinder 19 is fixed on the upper mold 2, the lower end of the guide rod 18 extending out of the guide cylinder 19 has a bar rack structure 18-1, the guide synchronization mechanism includes a synchronization shaft 20 and a gear 21 fixed at both ends of the synchronization shaft 20, the gear 21 is meshed with the bar rack structure 18-1 of the guide rod 18, and is used to realize the synchronous guidance of the guide rod mechanisms at both ends.

[0030] like Figure 2 and 3As shown, the fixed-length structure is specifically a fixed-length column 22-1, and the folding mechanism specifically uses the fixed-length column 22-1 to determine the length of the folding. The fixed-length columns 22-1 are arranged in a row in front of the lower mold 3. Because the upper mold 2 has a certain thickness and the folding length is short, the fixed-length columns 22-1 will be located directly below the upper mold 2. In order to avoid hindering the upper mold 2 from pressing down to fold, the fixed-length columns 22-1 can be elastically and telescopically installed in the mounting hole on the base through a spring mechanism and protrude from the upper plane of the base under the spring force of the spring. When the upper mold 2 presses down to fold, the upper mold 2 can push the fixed-length column 22-1 to overcome the spring force and fall, and will not hinder the upper mold 2 from pressing down to fold. When the upper mold 2 rises, the fixed-length columns 22-1 rise and reset under the spring force of the spring 13.

[0031] The working process of the transformer corrugated sheet conveying and folding composite machine is as follows: the corrugated sheet 23 is conveyed forward by the conveying mechanism; when the corrugated sheet 23 is conveyed to the front of the conveying arm mechanism 4, the correction lock tongue 5 is extended and inserted into the gap between the sheets of the corrugated sheet 23, and then the forward pushing mechanism 7 is actuated to push the correction lock tongue mechanism forward, and the correction lock tongue mechanism drives the corrugated sheet 23 forward by inserting the correction lock tongue 5 of the corrugated sheet 23, ensuring that the corrugated sheet 23 is correctly in place, specifically, the front end of the corrugated sheet 23 is close to the fixed-length column 22-1, That is, the corrugated sheet 23 is correctly in place; after the corrugated sheet 23 is correctly in place, the folding drive cylinder 17 of the upper die 2 drives the upper die 2 to press down, and cooperates with the lower die 3 to fold the front edge of the corrugated sheet 23 by 90 degrees. During the pressing process of the upper die 2, the pressing plate 8 of the spring pressing plate mechanism on the upper die 2 first contacts the lower die 3, and the lower mouth of the pressing plate 8 cooperates with the lower die 3 to clamp the front edge of the corrugated sheet 23 to ensure the stability of the subsequent folding. After the folding is completed, the upper die 2 is lifted, the folding correction mechanism is reset, and the corrugated sheet 23 is unloaded. The corrugated sheet 23 can be automatically unloaded and neatly stacked by a robot set separately.

[0032] In the above process, a photoelectric sensor or other type of sensor can be set on the front end of the conveying arm mechanism 4 or the base 1 of the folding mechanism to detect whether there is a corrugated sheet 23 conveyed to the front of the conveying arm mechanism 4, which is a prior art and will not be described in detail. During the folding process, the cylinder of the forward push mechanism 7 can always maintain pressure until the pressure is released and reset after the folding is completed, or the pressure is delayed when the upper mold 8-2 is pressed down.
