Detailed Description
As shown in fig. 1 and 2, the invention relates to a detection device for packaging bags, which comprises a frame 1, an upper press roller 2, a lower press roller 3, an upper electric contact 4, a lower electric contact 5, two upper press blocks 6, two press roller springs 7, two guide rollers 8, more than one photoelectric eye 9, an electric eye mounting frame 10 and a control circuit board (not shown in the figure).
The frame 1 comprises a base 11 and two opposite upright posts 12. The lower ends of the two upright posts 12 are vertically fixed on the base 11, and a chute 121 is formed in the middle of each upright post 12.
The two ends of the upper pressing roller 2 and the lower pressing roller 3 are respectively and movably sleeved in the sliding groove 121 of the upright post 12 of the frame 1, the upper pressing roller 2 is positioned above the lower pressing roller 3, a gap for the packaging bag to pass through is formed between the middle part of the upper pressing roller 2 and the middle part of the lower pressing roller 3, the upper electric contact 4 is respectively arranged at the two ends of the upper pressing roller 2, the lower electric contact 5 is respectively arranged at the two ends of the lower pressing roller 3, and the upper electric contact 4 is in contact with the lower electric contact 5. The two guide rollers 8 are both arranged on the frame 1 and respectively positioned in front of and behind the upper press roller 2.
The two upper pressing blocks 6 are respectively fixed in the sliding grooves 121 of the upright posts 12 of the frame 1 and are positioned above the upper pressing roller 2, and two ends of the pressing roller spring 7 respectively lean against the ends of the upper pressing blocks 6 and the upper pressing roller 2, so that the upper electric contact 4 and the lower electric contact 5 form electric contact.
The above photo-eyes 9 are respectively fixed on the top of the frame 1 through the photo-eye mounting frame 10, and in combination with fig. 3-5, the number of photo-eyes 9 is three in this embodiment, two photo-eyes 9 face two sides of a channel through which the packaging bag passes, and one photo-eye 9 faces the channel through which the packaging bag passes.
The upper electrical contact 4 and the lower electrical contact 5 are respectively and electrically connected with the control circuit board through wires, and the wires are connected with the optical fiber sensor in series.
The working principle of the invention is as follows:
as shown in fig. 1 and 2, a gap for passing a packaging bag 100 is arranged between the middle part of an upper pressing roller 2 and the middle part of a lower pressing roller 3, an upper electric contact 4 and a lower electric contact 5 are respectively arranged at two ends of the upper pressing roller 2 and the lower pressing roller 3, and the upper electric contact 4 and the lower electric contact 5 are closely attached. Once there is the waste material to be stained with when gluing on the through-hole of wrapping bag 100, the thickness of wrapping bag 100 can change for go up compression roller 2 and lower compression roller 3 gap and change, go up electrical contact 4 and lower electrical contact 5 and break away from the contact, the signal is transmitted to control circuit board, and control circuit board sends out the alarm, in time suggests the condition that the waste material is stained with on the through-hole of wrapping bag 100. The round hole of the packaging bag 100 is not normally washed off, and whether the bottom edge folding of the packaging bag 100 is normal or not is based on the principle of infrared induction. When the round hole is not normally punched and the bottom edge folding is abnormal, infrared rays cannot penetrate, namely signals cannot be received.
Function one: the waste was checked for sticking (punched out round holes or other debris). The implementation mode is as follows: the film passes through the gap between the upper pressing roller 2 and the lower pressing roller 3, when the thickness of the film with foreign matters is found to change, the upper pressing roller 2 and the lower pressing roller 3 lift the upper electric contact 4 and the lower electric contact 5 to be separated from contact, touch sensor signals are transmitted to the control circuit board, and the control circuit board gives an alarm to prompt the situation that the waste is stuck on the through hole of the packaging bag 100 in time.
And the function II: detecting whether the round hole of the packaging bag is normally flushed. The implementation mode is as follows: the principle of infrared induction is that the light rays emitted by the opposite irradiation of the upper photoelectric eye 9 and the lower photoelectric eye or the emission of the single photoelectric eye are utilized, and when the round hole is not normally washed off, the opposite irradiation or reflection cannot occur, so that an alarm is generated.
And the third function: detecting whether the width (or depth) of the folded edge of the packaging bag is normal. The implementation mode is as follows: the principle of infrared induction is that the opposite irradiation or reflection of the upper and lower photoelectric eyes 9 or the light emitted by the emission of a single photoelectric eye is utilized, and when the bottom edge folding is abnormal, the opposite irradiation or reflection cannot be generated, so that an alarm is generated.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, i.e., the equivalent changes and modifications to the invention as described in the claims and specification should be considered as falling within the scope of the invention.
