Abstract
The invention discloses a bag opening mechanism. The bag opening mechanism comprises a frame, a lower conveying roller component, a driving piece and a floating core ball. The lower conveying roller component comprises a first lower conveying roller, a second lower conveying roller and a lower conveying roller mounting plate. The lower conveying roller mounting plate is fixed on the frame; and the first lower conveying roller and the second lower conveying roller are mounted on the lower conveying roller mounting plate, and support the floating core ball. The floating core ball is connected with a connecting rod; and one end, far from the floating core ball, of the connecting rod is connected with a copying tool. The driving piece drives the first lower conveying roller and the second lower conveying roller to rotate. The bag opening mechanism cannot generate the abnormal condition of unsuccessful bag opening caused by smaller thickness of a drum film and bad electrostatic absorption bonding of the drum film, so that the drum film with the thickness smaller than 0.015 mm can be opened, the bag opening success rate reaches 100%, and the bag opening success rate is high. In addition, the bag opening mechanism is excellent in operation stability, quick in bag opening and high in bag opening efficiency.

Actuator is designed to motor 18, and this motor 18 is installed on the mounting base 111 of frame 11.With reference to Fig. 5, the rotating shaft of motor 18 is connected with the rotating shaft of the first lower roller 172, and the rotating shaft of the first lower roller 172 is simultaneously connected with the rotating shaft of the second lower roller 173 by transmission device 19.Transmission device 19 comprises the first gear 191, second gear 192, the 3rd gear 193 and the 4th gear 194, first gear 191 is installed in the rotating shaft of the first lower roller 172, second gear 192 and the 3rd gear 193 are installed on lower roller adapter plate 171 respectively, 4th gear 194 is installed in the rotating shaft of the second lower roller 173, first gear 191 engages with the second gear 192, second gear 192 engages with the 3rd gear 193, and the 3rd gear 193 engages with the 4th gear 194.Motor 18 drives the first lower roller 172 to rotate, rotation direction is as shown in the arrow below the first lower roller 172 in Fig. 4, the rotation of the first lower roller 172 is taken the first gear 191 to and is rotated, first gear 191 drives the second gear 192 to rotate, second gear 192 drives the 3rd gear 193 to rotate, 3rd gear 193 drives the 4th gear 194 to rotate, and the 4th gear 194 drives the second lower roller 173 to rotate, and rotation direction is as shown in the arrow below the second lower roller 173 in Fig. 4.
Upper roller assembly 20 is positioned at the top of lower roller assembly 17, and upper roller assembly 20 comprises on first carries the 202, second upper roller 203 and upper roller adapter plate 201.By screw, upper roller adapter plate 201 is installed on lower roller adapter plate 171.First upper roller 202 and the second upper roller 203 level are installed on upper roller adapter plate 201, first upper roller 202 and the second upper roller 203 are parallel to each other, first upper roller 202, second upper roller 203 is all mutually vertical with the second lower roller 173 with the first lower roller 172, floating core ball 21 is located between the first upper roller 202 and the second upper roller 203, and floating core ball 21 is located between the first upper roller 202 and the second upper roller 203.
As optimal technical scheme, the below of frame about 11 feed roller assembly 17 is fixed with four pilot bars 24, profiling fixture 23 is positioned at the space that this four pilot bars 24 surround, and can moving axially along pilot bar 24 in this space, thus make floating core ball 21 more steady when suspended motion.
Below the principle of work of bag openning body of the present invention is described in further detail.
With reference to Fig. 1, before bag openning body work, drum bag 13 is positioned on drum bag bracing frame 12, reel film 14 pulls out after on guiding roller 16 from drum bag 13, reel film 14 is opened, pass in upper roller assembly 20, floating core ball 21 is inserted in reel film 14 simultaneously, then reel film 14 passes in lower roller assembly 17, then connecting rod 22 and profiling fixture 23 are inserted in reel film 14 again, when profiling fixture 23 is inserted in reel film 14, reel film 14 is softened, now reel film 14 is fitted with the surface of the first lower roller 172 and the second lower roller 173 respectively.During bag openning body work, motor 18 drives the first lower roller 172 and the second lower roller 173 to rotate, first lower roller 172 and the second lower roller 173 are with movable reel film 14 to move down, thus reel film 14 is transmitted downwards, can upwardly floating core ball 21 when reel film 14 is sent downwards, and floating core ball 21 is held up, realize floating core ball 21 to float, thus reduce reel film 14 and floating core ball 21 and the first upper roller 202, second upper roller 203 and the first lower roller 172, pressure between second lower roller 173, make the transmission of reel film 14 more smoothly.Finally, reel film 14 is opened into required shape through profiling fixture 23 and is sent, thus realizes opening bag.
To sum up, bag openning body of the present invention, it there will not be because the Film Thickness Ratio of reel film is thinner, the electrostatic adherence adhesion of reel film is very severe, and cause out the unsuccessful abnormal condition of bag, bag can be opened to the reel film of thickness <0.015mm, open bag success ratio very high, reach very, because bag can be opened by the reel film thinner to Film Thickness Ratio, there will not be the reel film that Film Thickness Ratio need be used thicker in order to improve out bag success ratio, because this reducing material usage, reduce productive costs, cut the waste and environmental pollution.Further, bag openning body operational process of the present invention is smooth and easy, carries out out bag continuously, therefore good operation stability, opens bag speed fast, opens bag efficiency high.
The foregoing is only preferred embodiment of the present invention; not in order to limit the present invention; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement; if profiling fixture is taper or square or cylindrical etc., all should be included within protection scope of the present invention.
