Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 6, an automatic cutting device for a current collecting net 4 provided in an embodiment of the present invention includes a base 1, wherein an adjusting unit 2 and a pressure sensor 3 are disposed on the base 1, a cutting roller 10 is mounted on the base 1, the cutting roller 10 is used for winding a metal current collecting net 4, preferably, the cutting roller 10 is sleeved with a paper tube 11, the paper tube 11 is used for winding the metal current collecting net 4, a cutting knife 5 for cutting the current collecting net 4 is disposed on the adjusting unit 2, the cutting knife 5 is connected to the adjusting unit 2 through the pressure sensor 3, and the adjusting unit 2 controls a feeding of the cutting knife 5 based on detection data of the pressure sensor 3.

Specifically, according to the number of segments of the metal collecting net 4 wound on the paper tube 11 to be cut, the adjusting unit 2 is provided with a number of dividing cutters 5 which is less than the number of segments of the divided collecting net 4, during dividing, the dividing roller 10 is driven by external force to gradually approach the dividing cutters 5, the dividing rollers 10 rotate while moving, along with the movement of the dividing rollers 10, the collecting net contacts the dividing cutters 5, then the dividing cutters 5 divide and cut the collecting net 4, at the beginning, the pressure variation range of the dividing cutters 5 dividing and cutting the collecting net 4 is in the design range which is the range acceptable in the cutting process of the dividing cutters 5, the upper limit of the design range is determined in advance according to experiments, the maximum value of the cutting edge during the process of cutting the collecting net when the standard limit position is replaced, if the pressure variation range is 30N, the design range is 0-30N, and after the cutting edge abrasion amount of the dividing cutters 5 is large, the cutting edge of the cutting knife becomes dull, obviously, the pressure between the dividing and cutting knife 5 and the current collecting net 4 is increased and exceeds the design range, if the maximum value is larger than 30N, the pressure variation range of the dividing and cutting knife 5 for dividing and cutting the current collecting net 4 exceeds the acceptable design range, the pressure sensor 3 transmits the pressure signal to the adjusting unit 2 in an electric signal mode, the adjusting unit 2 controls the dividing and cutting knife 5 after receiving the signal, the dividing and cutting knife 5 is enabled to feed forwards, the worn knife edge is replaced by the non-worn knife edge, and then the dividing and cutting processing of the current collecting net 4 can be normally carried out.

In the prior art, the relative movement amount of the slitting knife 5 and the slitting roller 10 is realized by controlling the feeding amount by the driving unit, if the distance between the slitting knife 5 and the slitting roller 10 is 50cm, then either the slitting knife 5 feeds 50cm or the slitting roller 10 feeds 50cm each time, which is convenient to control, but has the disadvantages that firstly, the feeding amount is insufficient when the slitting knife 5 is worn too much, secondly, excessive feeding or insufficient feeding can be caused by part deformation and vibration in the using process, in the embodiment, further, the vertical change of the pressure sensor 3 is utilized, when the pressure is suddenly and greatly reduced in the process of slitting the collecting net 4 by the slitting knife 5, for example, the pressure is suddenly reduced by more than 30 percent, and even more, the pressure is suddenly reduced by more than 80 percent, and when the pressure signal detected by the pressure sensor 3 is suddenly reduced and is lower than the range, the slitting knife 5 completely cuts the collecting net 4, divide cutter 5 and fiber container 11 contact, stop the descending motion of dividing and cutting roller 10 this moment, the operation of cutting that not only can be timely understanding current collection net 4 goes on like this, can also prevent to divide cutter 5 and cut roller 10 direct contact, cause the damage of the two, also it cuts fiber container 11 at every turn and stops the feed motion of dividing and cutting roller 10 when making the pressure data that pressure sensor detected descend to appear also to divide the cutter, so on the one hand the safety volume is great, the safety volume is the thickness of fiber container, on the other hand feed detects alone at every turn, the deformation influence that the vibration is ageing to bring after having avoided long-term use is avoided, on the other hand again also need not redesign feed volume after changing cutter 5 at every turn, but can the direct use.

In this embodiment, the adjusting unit 2 includes the adjusting support 20, the dividing cutter 5 is installed on the adjusting support through a plurality of mounting structures, if the two ends of the dividing cutter 5 are respectively connected to the adjusting support through a connecting column, at this time, the pressure sensor 3 can be arranged on any one connecting column, although the pressure sensor 3 shares the pressure which may only be half of the dividing cutter 5 at this time, no matter what the data detected by the pressure sensor 3 is, the pressure sensor and the pressure data born by the dividing cutter 5 are in a direct proportion relation, the design range of the bearing pressure of the pressure sensor can be converted according to the pressure value determined in advance through experiments based on the pressure data, which is the prior art and is not repeated.

According to the automatic cutting device for the current collecting net 4, provided by the embodiment of the invention, the pressure sensor 3 is used for monitoring the pressure change generated when the dividing and cutting knife 5 cuts the metal current collecting net 4, the pressure change is converted into an electric signal and transmitted to the adjusting unit 2, the adjusting unit 2 can adjust the position of the dividing and cutting knife 5, so that the dividing and cutting knife 5 is fed forwards, and the worn knife edge is replaced by the unworn knife edge, therefore, the feeding time of the dividing and cutting knife 5 is more accurate, the adjusting unit 2 can feed forwards the corresponding length according to the worn length of the knife edge of the dividing and cutting knife 5 every time, and the problems of waste caused by the fact that the feeding speed of the knife is too high or defective products caused by the fact that the feeding speed of the knife is too low are avoided.
