In another embodiment, as shown in fig. 9, the guide frame 33 is connected to the guide roller 331 through a rotation shaft, and a pressure sensor 332 is disposed between the rotation shaft and the guide roller 331.

This device of lug connection is folded after the ejection of compact of strip 50 production machinery, and when the speed of the ejection of compact of strip 50 was less than the folding speed of this device, the circumstances that the ejection of compact strip 50 was dragged to the guide frame 33 can appear, and pressure sensor 332 detected the pressure on the guide roll 331 too big this moment, and this device stops promptly and waits for a certain time, for example 10 minutes, waits to continue folding again after the ejection of compact of strip 50 has certain length, avoids causing the damage to strip 50 or device.

In another embodiment, as shown in fig. 9, the bottom portions of the guide frames 33 in the opposite directions of the two guide rollers 331 are respectively provided with a telescopic strut 333.

As shown in fig. 7 and 8, when the guide frame 33 is translated to the folding inflection point of the strip 50, the telescopic strut 333 is extended to press the strip 50 downward, expanding the gap between the strip 50 and the guide frame 33, and facilitating the passage of the telescopic bar 22 through the gap.

In the above embodiment, since the telescopic pressing rod 333 is not provided, the distance between the belt blank 50 and the guide frame 33 at the folding inflection point is determined by the inclination angle of the belt blank 50 and the distance that the guide frame 33 translates beyond the folding inflection point, so that the height of the guide frame 33 at each folding inflection point needs to be high, and the inclination angle of the belt blank 50 can ensure that the gap between the rest of the translation frames 32 or the guide frame 33 is enough for the telescopic rod 22 to pass through until the subsequent inflection point, and the guide frame 33 needs to exceed the folding inflection point of the belt blank 50 by a longer distance to form a larger gap at the inflection point for the telescopic rod 22 to pass through, so that the gap between the folded belt blanks 50 is larger, and the height of the whole device needs to be higher when the number of folding times is larger.

The telescopic pressing rod 333 is arranged to extend when the guide frame 33 just exceeds the folding inflection point, so as to enlarge the gap between the strip blank 50 and the translation frame 32 or the guide frame 33, so that the telescopic rod 22 can pass through the guide frame 33 conveniently, the reciprocating stroke of the guide frame 33 is shorter, meanwhile, the telescopic pressing rod 333 plays a role of pressing the strip blank 50 downwards, so that the strip blank 50 does not need to be inclined upwards (as shown in fig. 6) in the folding process, the folding can be performed in a flush or even downwards inclined manner (as shown in fig. 7 and 8), the gap between the folded strip blanks 50 is determined by the diameter of the telescopic rod 22, the gap between the folded strip blanks 50 is smaller under the same condition, the folding of the strip blanks 50 is tighter, the overall height is lower, and the device with the same height can perform folding for a higher number of times.

In another embodiment, the end of the telescopic pressing rod 333 is provided with a pressing roller 334, and since the width of the belt blank 50 is various conditions such as 8 cm to 20 cm, when the belt blank 50 is wider, the telescopic pressing rod 333 directly presses the belt blank 50, which may cause the two sides of the belt blank 50 to tilt, and affect the penetration of the telescopic rod 22, by providing the pressing roller 334, the belt blank 50 can be pressed in the whole width direction of the belt blank 50, and the pressing effect is better.

In another embodiment, shown in FIG. 10, an end positioning device 60 is provided on the folding station 40.

In this embodiment, the end positioning device 60 includes an end pressing plate 61 disposed above the folding table 40, the bottom of the end pressing plate 61 is provided with an inserting strip 62, the inserting strip 62 extends downward, the bottom of the inserting strip 62 is provided with a triangular first limiting block 63, the folding table 40 is rotatably connected with a rotating wheel 64 through a rotating shaft, and a side surface of the rotating wheel 64 is provided with a triangular second limiting block 65.

During positioning, the end part of the strip blank 50 is inserted into a gap between the end pressing plate 61 and the folding table 40, the end pressing plate 61 is pressed downwards, after the strip blank 50 is pressed by the end pressing plate 61, the rotating wheel 64 is rotated, the second limiting block 65 blocks the first limiting block 63, namely, the inserting strip 62 cannot be reset upwards, and at the moment, the positioning of the end part is completed.

The end of the strip 50 is positioned and secured by the end positioning device 60 for subsequent folding.

It is understood that the tip positioning device 60 may be positioned in various other ways, and will not be described in detail herein.

In another embodiment, a counting device for recording the number of round trips of the guide frame 33 is further included.
