Description

Automatic groover of carton processing production

Technical Field

The invention relates to the technical field of carton processing equipment, in particular to an automatic grooving machine for carton processing production.

Background

The carton fluting is that the fluting cutter through the carton groover cuts out the folding line of lid about the carton and the folding line of box side (all around) on monoblock cardboard, and convenient subsequent processes such as customization are processed into the carton with the cardboard. The depth of the slot of the paper board in the slot can be different, for example, the folding lines of the upper cover and the lower cover of the paper box generally need to be completely cut to ensure that the parts of the upper cover and the lower cover (generally only one end is connected with the paper board, and the other three ends are separated from the paper board) are separated from the paper board, so that the manufacture of the paper box is facilitated. The side ends around the box body of the carton only need to be folded, grooving is not carried out under the general condition, and only for harder and thicker paperboards, in order to facilitate folding and ensure the attractiveness of the subsequent made carton, grooving with less depth is carried out on the inner side ends around the paperboards (namely the inner side ends around the finished carton) to be used as folding lines.

The existing slotting machine is limited by the structure, when the slotting machine works, the paper boards are generally conveyed to the lower end of a slotting cutter continuously and circularly through electric plate type or wheel type conveying belt equipment for slotting, only one pair of electric compression rollers which are distributed up and down and run synchronously and reversely are arranged on the slotting machine at the rear side end of the slotting cutter to press the moving paper boards, then the paper boards move to the lower end of the slotting cutter to be slotted through the rotating slotting cutter, and because only one pair of electric compression rollers are arranged, the probability of upwarp exists when the front end of the paper boards moves to the lower end of the slotting cutter, so that the probability of causing the front end of the paper boards to directly contact the rear upper part of the slotting cutter and then to be pressed; because the cardboard front end contacts the slotting tool first and is from top to bottom, push down the fluting by the slotting tool, so the cardboard front end can be all cut open by the slotting tool, and the groove that the slotting tool was opened is the inboard end groove all around of follow-up carton like this, and when not needing to cut open entirely, will cause the carton quality decline of follow-up preparation.

Moreover, although the existing grooving machine can realize grooving of paper in multiple directions through a plurality of transversely distributed grooving blades, a plurality of grooving cutters are arranged on the same rotating shaft and driven by a motor speed reducing mechanism, that is, the plurality of cutters cannot realize adjustment of different heights, and only adjustment of the whole height can be realized, so that when the grooving degree of a processed paperboard is changed, for example, the grooving depth of the inner side end of the periphery of the paperboard needs to be increased or decreased (even the inner side end of the periphery is not grooved), an operator only takes off the rotating shaft when the inner side end of the periphery of the carton does not need to be grooved, and then takes off the grooving cutters at corresponding positions, and the purpose of preventing the inner side end of the periphery from being grooved can be achieved; when the grooving depth of the inner side end around needs to be changed, the grooving depth of the inner side end around can be changed only by taking down the rotating shaft and then replacing the rotating shaft with grooving cutters with different heights (namely different diameters). When taking off and installing the slotting tool of different diameters, still need dismouting pivot etc. can bring very big inconvenience for operating personnel, be unfavorable for improving work efficiency, and also can increase the unnecessary cost of labor expenditure of production side.

Disclosure of Invention

In order to overcome the defects that the front end of the existing grooving machine has upwarp probability during grooving of a paperboard due to the limitation of the structure, further the grooving quality is reduced, when the grooving depth is changed and the grooving is reduced, a rotating shaft needs to be disassembled and assembled to realize the removal or the replacement of grooving cutters with different specifications, inconvenience is brought to operators, the work efficiency is not improved, and unnecessary labor cost expenditure is increased in a production method, the invention provides the grooving machine with two sets of electric compression rollers, after the two sets of electric compression rollers simultaneously press the moving paperboard during working, the grooving cutters perform grooving operation on the paper again, the front end of the paperboard is prevented from upwarp, and when the grooving point is reduced and the grooving depth is changed, the dismounting operation is not needed, the change of the grooving depth can be realized only by simply adjusting a time control switch, or the corresponding paperboard point position is not grooved by simply closing a power switch, therefore, the slotting quality of the paper boards is ensured, convenience is brought to operators, the working efficiency is improved, and unnecessary labor cost expenditure of a production party is reduced.

The technical scheme adopted by the invention for solving the technical problems is as follows:

Furthermore, each set of time control switch comprises two time controller modules and relays, which are connected through circuit board wiring, the normally open power output ends and the negative power input ends of the two time controller modules are respectively connected with the positive and negative pole power input ends of the first relay and the second relay, the positive trigger power input ends of the first time controller module and the second time controller module are respectively connected with the normally open contact end and the normally closed contact end of the third relay, the negative power input ends and the negative trigger signal input ends of the first time controller module and the second time controller module are respectively connected with the negative control power input ends of the third relay and the first relay and the second relay, and the 1 pin of the positive power input end of the first time controller module and the positive power input end of the second time controller module are connected with the first relay and the second relay, and the anode of the third relay controls the input end of the power supply to be connected.

According to the invention, when the slotting point is reduced and the slotting depth is changed, the disassembly operation is not required, and the distance between the electric telescopic rod driving motor and the slotting cutter up and down can be changed by changing the time of the time control switch output power supply, so that the purpose of changing the slotting depth of the paperboard is achieved. According to the invention, the non-grooving of the paper board at the corresponding position can be realized only by simply closing two power switches, and after the power switches are closed, because the corresponding set of electric telescopic rod does not descend any more, the corresponding set of motor does not drive the corresponding grooving cutter to rotate any more (simultaneously, one power switch connected with the motor is closed), so that the control purpose of the non-grooving of the paper board at the lower end of the corresponding grooving cutter is achieved. The invention can change the front-back distance of a plurality of sets of electric telescopic rods under the fixed plate through simple operation, thereby achieving the purpose of adjusting the front-back slotting position of the paper board. The invention ensures the slotting quality of the paperboard, brings convenience to operators, improves the working efficiency and reduces unnecessary labor cost expenditure of a production party. Based on the above, the invention has good application prospect.

As shown in fig. 1 and 2, two sets of

electric compression rollers

21 and 22, a motor of the electric plate conveyor belt device 1, and power input ends of three sets of motors 4 are respectively connected in series through a power switch and connected with a 380V power supply through a lead; the power input ends 1 and 2 of a regulated power supply U1 and two poles of an alternating current 220V power supply are respectively connected through leads, two

ends

3 and 4 of the power output end of a regulated power supply U1, two ends VCC and GND of the power input end of a photoelectric switch U2, and 1 and 2 pins of a first part time controller module U3 and a second part time controller module U4 (or U3N and U4N) at two ends of the power input end of three sets of time control switches are respectively connected through leads; the 3-pin signal output end of the photoelectric switch U2 is connected with the positive power supply input end of the signal input end relay K (or KN) of the three sets of time control switches through a lead; in the three sets of time control switches and the three sets of electric telescopic rods, the positive and negative poles of each time control switch, the negative and positive poles of each time control switch and the two normally open contact ends of the power output end relay K1 (or K1N), the two normally open contact ends of the relay K2 (or K2N) and the positive and negative poles of each set of electric telescopic rod M (or MN) are respectively connected through leads.

As shown in fig. 1 and 2, after the 220V ac power enters the two terminals 1 and 2 of the power input of the regulated power supply U1, the regulated power supply U1 outputs a stable 24V dc power to the two terminals 1 and 2 of the power input of the optoelectronic switch U2 and the first and second time controller modules U3 and U4 (or U3N and U4N) of the three sets of time control switches under the action of its internal circuit, so that the optoelectronic switch U2 and the first and second time controller modules U3 and U4 (or U3N and U4N) of the three sets of time control switches are in an electrically powered operating state. After power switches connected with the power input ends of the two sets of

electric compression rollers

21 and 22, the motor of the electric plate type conveying belt device 1 and the three sets of motors 4 are opened, the

electric compression rollers

21 and 22, the motor of the electric plate type conveying belt device 1 and the three sets of motors 4 are in an electrified working state (the three sets of motors 4 respectively drive the three sets of slotting tools 8 to respectively rotate). The paper boards output in the previous process are continuously conveyed from right to left at a certain distance through the upper end of the conveying belt 102 of the electric plate type conveying belt equipment 1, and each set of electric compression roller is provided with a pair of rollers which are distributed up and down and run synchronously and reversely, so that when the electric compression roller works, the rollers distributed up and down by the two sets of

electric compression rollers

21 and 22 simultaneously press the moving paper boards (the paper boards continue to move from the left side ends between the two rollers), and when the slotting cutter 8 subsequently slots the paper, the front ends of the paper boards are prevented from upwarping (the front ends and the rear ends in the middle of the paper boards are simultaneously pressed by the two sets of

electric compression rollers

21 and 22, and the front ends cannot upwarp any more), so that the front ends of the paper boards are not directly contacted with the upper part of the rear end of the slotting cutter 8 any more, and then are pressed.

As shown in fig. 1 and 2, after the left front end paperboard is conveyed to the right side of the mounting frame 7, infrared light emitted by a detection head of the photoelectric switch U2 is shielded, and under the action of an internal circuit of the photoelectric switch U2, a pin 3 of the photoelectric switch U2 outputs a high level to enter a positive power supply input end of a relay K (or KN), so that the relay K (or KN) is electrified to attract the control power supply input end and a normally open contact end to be closed; because the first and second time controller modules U3 and U4 (or U3N and U4N) of the three sets of time control switches are in an electrified working state at the moment, the positive pole of the first time controller module U3 (or U3N) triggers the connection of the power input terminal pin 3 and the normally open contact terminal of the relay K (or KN), so, at the moment, the trigger signal is input to the first time controller module U3 (or U3N), the time controller U3 (or U3N) outputs 1 second high level to enter the positive power input terminal of the relay K1 (or K1N) under the action of the internal circuit and the action of 9 pin output power time set by production technicians, and then the relay K1 (or K1N) can be electrified to attract two control power input terminals of the relay 1 second and two normally open contacts of the relay K1 are respectively closed; because, two normally open contact ends of the relay K1 (or K1N) of the three sets of time control switches are respectively connected with the positive and negative pole power input ends of the three sets of electric telescopic rods M (or MN), at the moment, the three sets of electric telescopic rods M (or MN) can be powered on to work, the plunger rods of the three sets of electric telescopic rods can simultaneously move downwards and drive the motor and the slotting cutter which are arranged below the plunger rods to move downwards for 1 second, at the moment, the paperboard continues to move, and when the motor just moves to the lower end of the slotting cutter 8, the slotting cutter 8 can be slotted from left to right. When the slotting of the paper board is finished and the paper board moves to the next station from the lower end of the slotting cutter to the left end of the conveying belt equipment, as the detecting head of the photoelectric switch U2 is not blocked any more, the 3 feet of the photoelectric switch U2 stop outputting high level, and the relay K (or KN) is not electrified to attract the input end of the control power supply and the normally closed contact end to be closed any more; because the 3 pin of the positive trigger power input end of the second time controller module U4 (or U4N) is connected with the normally closed contact end of the relay K (or KN), at the moment, the trigger signal is input into the second time controller module U4 (or U4N), the 9 pin of the time controller U4 (or U4N) outputs 1 second high level into the positive power input end of the relay K2 (or K2N) at an interval of 0.1 second under the action of the internal circuit and the action of 93 pin power output time set by production technicians (the interval time ensures that the slotting cutter fully slots the rear end of paper), and then the relay K2 (or K2N) can be powered to attract the two control power input ends and two normally open contact ends of the power supply to be respectively closed for 1 second; because two normally open contact ends of the relay K2 (or K2N) of the three sets of time control switches are respectively connected with the negative and positive pole power input ends of the three sets of electric telescopic rods M (or MN), at the moment, after the three sets of electric telescopic rods M (or MN) are powered on to work, the plunger rods of the three sets of electric telescopic rods M (or MN) can simultaneously move upwards and drive the motor and the slotting cutter which are arranged below the plunger rods to move upwards for 1 second to return to the initial state, and preparation is made for slotting the next paper board. After the next paper board moves to the right side end of the mounting frame 7 and shields infrared light emitted by a detecting head of the photoelectric switch U2, the relay K (or KN) can be electrically attracted, the process is completely consistent with the process, three sets of M (or MN) plunger rods of the electric telescopic rods can simultaneously descend for 1 second and drive a motor and a slotting cutter which are arranged below the plunger rods to descend, and the process is continuously circulated, so that a plurality of paper sheets which are circularly conveyed on a conveying belt of conveying belt equipment can be continuously slotted. In the invention, when the slotting depth of one or more slotting knives to the paper board needs to be adjusted, the power supply time output by the three sets of time controller modules of the first part and the second part of the time controller module U3 and U4 (U3N and U4N) of the time control switch U3 and U4 is simply adjusted, when the power supply time output by the 9 pins is relatively long, the three sets of M (or MN) plunger rods of the electric telescopic rods simultaneously descend, and the distance for driving the motor and the slotting knives arranged below the plunger rods to descend is relatively larger, so that the slotting depth to the paper board is relatively deeper; when the time of outputting the power supply by the 9 feet is relatively short, the three sets of M (or MN) plunger rods of the electric telescopic rods simultaneously move downwards, and the distance for driving the motor and the slotting cutter which are arranged below the plunger rods to move downwards is relatively smaller, so that the slotting depth of the paper board is relatively shallower. In the invention, if the number of the transverse slots of the paper board needs to be reduced, one or two sets of power switches S (SN) for controlling three sets of time control switches at the corresponding slot positions and the time controller modules U3 and U4 (or U3N and U4N) at the first part and the second part can be closed (and the power supply of a motor for slotting the corresponding positions is closed), and subsequently, because the electric telescopic rod does not move downwards any more, the corresponding positions of the paper board can not be slotted due to the spacing distance between the slotting cutter and the upper end of the paper board, thereby meeting the requirement of the actual number of the slots. In the invention, the motor, the electric telescopic rod and the slotting cutter are not limited to three sets, and a plurality of sets can be adopted, so that more slots can be formed on the paper board at one time. In fig. 2, relays K, K1, K2 are 24V dc relays of the brand song.
