Description
Technical Field
The invention relates to the technical field of cigarette production equipment, in particular to a packet pushing device of a cigarette box outer transparent paper packaging machine.
Background
The output of the cigarette packet in the YB55 box outer transparent paper packaging machine is completed by a duplex packet pushing rod device, as shown in fig. 1, the existing duplex packet pushing rod device comprises a duplex packet pushing rod 1', a left packet pushing block 31' and a right packet pushing block 32' which are rotatably arranged at the lower end of the duplex packet pushing rod 1', left reset springs 21' with two ends respectively connected with the duplex packet pushing rod 1' and the left packet pushing block 31', right reset springs (not shown) with two ends respectively connected with the duplex packet pushing rod 1' and the right packet pushing block 32', a bumper 4' arranged above heat sealing channels 6' at the two ends and a proximity switch detector 5' arranged above the bumper 4 '. In the process of outputting the cigarettes, the two cigarettes with the two ends folded and folded are lifted to the positions to be pushed corresponding to the left pushing block 31' and the right pushing block 32' by the folding device, the left pushing block 31' and the right pushing block 32' push the two cigarettes stacked up and down together to move forward to the two end heat-sealing channels 6', the left side and the right side of the two end heat-sealing channels 6' are provided with two opposite heat-sealing lozenges 61' for carrying out end heat sealing on the cigarettes in the two end heat-sealing channels 6', the bottom side of the two end heat-sealing channels 6' is provided with a bearing plate 62' for supporting the cigarettes in the two end heat-sealing channels 6', and the foremost two cigarettes stacked up and down in the two end heat-sealing channels 6' are pushed by the cigarettes at the back to enter the output rotary table 7' (see fig. 2). When the duplex pushing rod 1 moves backwards in a return stroke, the left pushing block 31' and the right pushing block 32' touch two vertically stacked cigarette packs to be pushed next lifted by the stacking device and respectively overcome the tensile force of the left return spring 21' and the right return spring to rotate anticlockwise around the pin shaft, and when the duplex pushing rod 1' moves leftwards to approach the end position, the left pushing block 31' and the right pushing block 32' restore to the original positions under the tensile force of the left return spring 21' and the right return spring respectively due to the fact that the lower part is smokeless, so that the next pushing is ready. When the cigarette packet is blocked in the heat sealing channels 6 'at the two ends in the cigarette packet pushing process, the safety rod 4' is lifted upwards due to upward acting force of the cigarette packet, and the proximity switch detector 5 'arranged on the upper side of the safety rod 4' sends out a signal to stop the equipment. It should be noted here that the existing duplex bag pushing rod device has the following disadvantages:

2) Because the left push-pack block 31' and the right push-pack block 32' are made of plastic, in order to prevent the left return spring 21' and the right return spring from damaging the left push-pack block 31' and the right push-pack block 32' respectively due to overlarge generated elastic force, the left return spring 21' and the right return spring in the existing duplex push-pack rod device are springs with small diameters of tension spring wires, so that the left return spring 21' and the right return spring have small strength, the inertia of the left push-pack block 31' and the right push-pack block 32' which do high-speed reciprocating motion are difficult to overcome, fatigue and plastic denaturation are easy to occur to fail, and the left push-pack block 31' and the right push-pack block 32' cannot accurately reset, so that quality defects such as smoke pack extrusion deformation, smoke pack scratch and smoke crease in the next push-pack process are caused.
3) When the left pushing block 31 'and the right pushing block 32' cannot normally act, two vertically stacked cigarettes lifted to the to-be-pushed position by the stacking device cannot be timely pushed to the two-end heat sealing channels 6', and the stacking device can continuously convey the subsequent cigarettes to the to-be-pushed position, so that the cigarette pack at the to-be-pushed position is blocked and fails, and the double pushing rod 1' is damaged.

The rear side of the base 62 is supported on a hook piece 122 fixedly connected with the support 1, specifically, the middle portion 12 of the rear side of the lower surface of the base 62 is sunk inwards to form a notch 622, the upper end of the hook piece 122 is fixed on the middle portion 12 of the support 1 through a screw, the lower end of the hook piece 122 extends downwards out of the middle portion 12 of the support 1, and the lower end of the hook piece 122 is hooked on the notch 622 formed on the lower surface of the base 62. A first compression spring 64 is arranged between the base 62 and the support 1, specifically, the lower surface of the middle part 12 of the support 1 is opposite to the upper surface of the base 62 with a space therebetween, the middle part 12 of the base 62 is provided with a compression spring positioning hole 623, and the lower end of the first compression spring 64 is positioned in the compression spring positioning hole 623, and the upper end is abutted against the lower surface of the middle part 12 of the base 62. The first compression spring 64 has the following specifications: the diameter of the spring wire is 0.8mm, the outer diameter of the spring is 9mm, the free height is 28mm, the actual total number of turns of the spring is 16, and the carbon spring wire is selected as the material. The two first safety bars 63 are respectively connected to the left and right sides of the base 62, and the lower side of each first safety bar 63 has a flat and horizontal first limiting surface for contacting with the tobacco bale. The front end of the first bumper 63 is fixed to the base 62, and the rear end of the first bumper 63 extends backward to a position directly above the to-be-pushed position of the tobacco package, so that when the tobacco package is blocked at the to-be-pushed position, the tobacco package can upwards prop against the first limiting surface at the lower side of the first bumper 63. The two first safety bars 63 are spaced apart and parallel, and the spacing between the two first safety bars 63 allows the bale pushing bar 2 to move unimpeded. In this way, when the two vertically stacked cigarettes lifted to the to-be-pushed position by the stacking device cannot be timely pushed to the heat-sealing channels at the two ends due to the fact that the pushing block 3 in the pushing device cannot normally act, if the stacking device continues to convey the subsequent cigarettes to the to-be-pushed position, the cigarettes staying at the to-be-pushed position can lift the limiting part, at the moment, the first position detector 61 detects that the limiting part lifts up and sends out a corresponding signal to remind an operator of timely stopping and overhauling, and therefore position running and deformation caused by the fact that the pushing rod 2 is blocked by the cigarettes are effectively avoided. Since the interval between the two first safety bars 63 allows the bag pushing bar 2 to move without obstruction, and the yielding through hole 221 aligns with the first detector, the overall structure of the bag pushing device is more compact, and smooth reciprocating movement of the bag pushing bar 2 can be ensured.
Further, the bag pushing device further comprises a second safety mechanism. The second safety mechanism comprises a supporting seat 71 fixed on the front side surface of the support 1, a second safety rod 72 movably connected with the supporting seat 71 and elastically abutted against the supporting seat, and a second position detector 74 mounted on the supporting seat 71 and used for detecting the position change of the second safety rod 72, and the lower side of the second safety rod 72 is provided with a second flat limiting surface used for contacting with a cigarette packet. Referring to fig. 8, the support base 71 is L-shaped, and has a vertical plate 711 and a horizontal plate 712, a screw passes through the first mounting hole 121 of the middle portion 12 of the support base 1 and is connected to the vertical plate 711 of the support base 71, so as to fix the support base 71 and the support base 1 together, the horizontal plate 712 has two circular holes 7121 penetrating up and down, the upper side of the second safety rod 72 has two cylinders 721, two second compression springs 73 are respectively sleeved outside the two second cylinders 721, the two cylinders 721 are respectively inserted into the two circular holes 7121 from bottom to top, and nuts are respectively fastened at the upper ends of the two cylinders 721, so that the second safety rod 72 is movably connected to the support base 71, and the upper and lower ends of the two second compression springs 73 are respectively abutted against the horizontal plate 712 of the support base 71 and the second safety rod 72, so that the second safety rod 72 is elastically abutted against the support base 71. The second position detector 74 may be a proximity switch. It will be appreciated by those skilled in the art that when a packet of cigarettes is jammed in the heat-sealed channels at both ends, the packet will lift the second bumper 72 (as described in the background section), and at this time, the second position detector 74 detects that the second bumper 72 lifts and sends a corresponding signal to remind the operator to stop and repair in time, so as to effectively avoid further damage to the pushing device and avoid the deformed packet from being mixed into the subsequent station.
