Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a packaging film connects detection device, including the pay-off platform 1 that is used for conveying the product and the controller 6 that is used for automatic control, one side fixed mounting of pay-off platform 1 has and examines test table 2, it is equipped with lever drive mechanism 3 on 2 to examine test table, lever drive mechanism 3 installs the lever 31 on examining test table 2 including rotating, distribute at product top surface and bottom surface and be used for detecting the activity pinch roller 32 and the fixed pinch roller 33 of product thickness, wherein fixed pinch roller 33 with examine test table 2 fixed connection, the one end at lever 31 is fixed to activity pinch roller 32, the other end of lever 31 is fixed with optical feedback paster 34, the top of optical feedback paster 34 is equipped with photoelectric sensor 5 that is used for detecting signal,

photoelectric sensor

5 and 6 electric connection of controller.

In this embodiment, a lever transmission mechanism 3 is disposed on the inspection table 2, the lever transmission mechanism 3 includes a lever 31 rotatably mounted on the inspection table 2, a movable pressing wheel 32 and a fixed pressing wheel 33 distributed on the top and bottom of the product for detecting the thickness of the product, wherein the fixed pressing wheel 33 is fixedly connected with the inspection table 2, the movable pressing wheel 32 is fixed at one end of the lever 31, the other end of the lever 31 is fixed with an optical feedback patch 34, a photoelectric sensor 5 (model E18-D80NK) for detecting signals is disposed above the optical feedback patch 34, the photoelectric sensor 5 is electrically connected with the controller 6, the movable pressing wheel 32 and the fixed pressing wheel 33 are distributed on the top and bottom of the product by the lever transmission mechanism 3, when the product is in transmission, the thickness changes, the movable pressing wheel 32 is lifted by the product to a certain height, and the other end of the lever 31 is lowered, because the length of the first force arm 312 at one side of the movable pinch roller 32 is smaller than that of the second force arm 313 at one side of the optical feedback patch 34, when the movable pinch roller 32 is lifted a small distance, one side of the optical feedback patch 34 is still lifted a large distance, at the moment, the feedback time of an optical signal detected by the photoelectric sensor 5 is prolonged, the judgment distance is increased, the photoelectric sensor 5 transmits a detection signal to the controller 6, a meter counter in a control system starts to count a preset length from a thickness detection position to the tail end of a production line, namely, the measurement is carried out according to the preset length, when the detected connector reaches the tail end along the production line, the meter counter sends a signal, the tail end of the production line acts to select, reject and alarm, a rear fan 7 blows and discharges a packaging bag of the connector, a full-automatic detection rejection mode is realized, compared with manual detection, the detection accuracy and the detection efficiency are greatly improved, the labor cost is reduced, and the automation degree is higher.

Specifically, the lever 31 includes a rotating shaft 311, a first force arm 312 and a second force arm 313, the first force arm 312 and the second force arm 313 are rotatably mounted on the inspection table 2 through the rotating shaft 311, the movable pressure wheel 32 is fixedly connected with the first force arm 312, the optical feedback patch 34 is fixed on the second force arm 313, the length of the second force arm 313 is equal to fifteen times of the length of the first force arm 312, when the product is in a transmission process, because the thickness changes, the movable pressure wheel 32 can be lifted by the product to a certain height, at the same time, the other end of the lever 31 can be lowered, because the length of the first force arm 312 on one side of the movable puck 32 is less than the length of the second force arm 313 on one side of the optical feedback patch 34, therefore, when the movable pressure wheel 32 is lifted a small distance, one side of the optical feedback patch 34 is still lifted a large distance, and the feedback time of the optical signal detected by the photoelectric sensor 5 is prolonged, so that the distance is judged to be increased.

Specifically, the sensor mounting base 21 is fixed above the detection table 2 close to the optical feedback patch 34, the photoelectric sensor 5 is fixed on the sensor mounting base 21 in a threaded manner, and the photoelectric sensor 5 can be installed more stably by arranging the sensor mounting base 21.

Specifically, the top of pay-off platform 1 is equipped with pinch roller 4, and pinch roller 4's intermediate position department fixed mounting has back shaft 41, and pinch roller 4 rotates through back shaft 41 to be connected between examining test table 2 with detecting, through setting up pinch roller 4, at the in-process of product conveying, pinch roller 4 can give the pressure that the product lasts, prevents that product deformation arch from bringing the influence for detecting.

Specifically, the detection table 2 is further provided with a fan 7 along the transmission direction of the feeding table 1, the fan 7 is fixedly connected with the detection table 2, the fan 7 is electrically connected with an external power supply, after receiving a signal fed back by the photoelectric sensor 5, the controller 6 controls the fan 7 (model FH50-B-12L-15) to start and stop, the fan 7 is used for blowing air, and unqualified products are removed.

The utility model discloses a theory of operation and use flow: after the utility model is installed, through setting up lever drive mechanism 3 of lever type, activity pinch roller 32 and fixed pinch roller 33 distribute at product top surface and bottom surface, when the product is in the transmission, because thickness changes, activity pinch roller 32 can be lifted by the product and raised a certain height, the other end of lever 31 can descend at this moment, because first force arm 312 length of activity pinch roller 32 one side is less than second force arm 313 of light feedback paster 34 one side, so when activity pinch roller 32 lifts very little distance, light feedback paster 34 one side still can lift great distance, the light signal feedback time that photoelectric sensor 5 detected at this moment lengthens, judge from this that the distance increases, photoelectric sensor 5 passes detected signal to controller 6, meter ware begins to measure predetermined length among the control system, this length is the length of thickness detection position to the production line end, measure according to predetermined length ground promptly, think the joint that is detected when reaching the end along the production line, meter rice ware signals, the terminal action of production line is selected, is rejected, alarming function, and the wrapping bag that this joint of discharge is bloied by the fan 7 at rear realizes full automatization's detection and rejection mode, compares in artifical the detection, has improved detection precision and detection efficiency greatly, reduces the human cost, and degree of automation is higher.
