Detailed description of the invention

Referring to figs. 1 through Fig. 3, the utility model belt cutting press embodiment is described further.

As Fig. 1, shown in 2, a kind of belt cutting press, comprise frame 1, hob cutter 2, drive cylinder 3 and drive motors 5, the described cutter 2 that hobs is installed in frame 1 for hobbing adhesive tape, described driving cylinder 3 hobs cutter 2 in order to driving and vertically hobs motion, the side of described frame 1 is also provided with the delivery roll 4 for transmitting adhesive tape, described drive motors 5 is coupled to power end and rotates in order to drive delivery roll 4, in described frame 1, immediately below cutter, place is provided with pressure sensor A1, described pressure sensor A1 is in order to detect the pressure output detections signal that hob cutter 2 pairs of adhesive tapes, described pressure sensor A1 is coupled with warning unit A2 and alarm unit A3, and described warning unit A2 is in order to receive detection signal and to export caution signal, and described alarm unit A3 receives detection signal and cuts off the power supply of drive motors 5.

Frame 1 is arranged and hobs cutter 2, drive cylinder 3, delivery roll 4 and drive motors 5, drive motors 5 is in the inside of casing, just signal in figure, and specifically do not show, this is prior art, and driving delivery roll 4 to rotate by drive motors 5 is also prior art, hob cutter 2 by air cylinder driven vertically to move up and down to realize hobbing simultaneously, the course of work of its existing hobbing press be delivery roll 4 by rubber belt transmission to hobbing cutter 2 place, make to hob cutter 2 by cylinder to fall, carry out hobbing adhesive tape, and adhesive tape has two-layer, one deck is adhesive tape body, that tool is sticking, another layer is the basic unit of this bulk viscosity of protective tapes.Need in process adhesive tape body to hob there is cut channel, but basic unit can not cut off, and makes adhesive tape or continuous print.Therefore the improvement made on the basis of existing technology.

Be used for detecting by arranging pressure sensor A1 in frame 1 pressure hobbing cutter 2, and pressure sensor A1 connects warning unit A2 and alarm unit A3, if pressure sensor A1 detects that pressure is bigger than normal, will be sent warning signal by warning unit A2, or the pressure that pressure sensor A1 detects is excessive, adhesive tape cutting will be made, unfavorable to production, now alarm unit A3 will make drive motors 5 power-off, and report to the police, make whole equipment cisco unity malfunction to prevent drive motors 5 from working on.

As shown in Figure 3, hob time cutter 2 falls and will touch pressure sensor A1, the pressure hobbing cutter 2 pairs of adhesive tapes is detected with this, pressure sensor A1 adopts MPX2000 series pressure sensor A1 of the prior art, or the miniature LOAD CELLS of employing RSW06 is also the one in pressure sensor A1.The force value detected can be converted into detection signal, detection signal is to be voltage signal, and when pressure is larger, magnitude of voltage is larger.

Warning unit A2 comprises the first comparing unit A21, the first reference voltage unit A22 and the first performance element A23; Described first reference voltage unit A22 is in order to produce the first voltage signal; Described first comparing unit A21 is coupled to pressure sensor A1 and the first reference voltage unit A22, in order to receive detection signal and the first voltage signal respectively, and exports the first drive singal; Described first performance element A23 is coupled to the first comparing unit A21 in order to receive the first drive singal and to export caution signal.Described first performance element A23 comprises the first triode Q1 and emergency warning lamp LD, and the base stage of described first triode Q1 is coupled to the output of the first comparing unit A21, and colelctor electrode is coupled to one end of emergency warning lamp LD, grounded emitter; The other end of described emergency warning lamp LD is connected with power supply.

First comparing unit A21 is the multilevel comparator that comparator LM1 or multiple comparator LM2 form.The present embodiment is single comparator LM1, the in-phase end Bonding pressure sensors A 1 of comparator LM1, end of oppisite phase connects the output of the first reference voltage unit A22, potentiometer Rp1 is adopted to regulate the magnitude of voltage of reference voltage, by setting the magnitude of voltage of reference voltage, when the magnitude of voltage of the detection signal that pressure sensor A1 exports is greater than reference voltage, comparator LM1 exports high level, make the first triode Q1 conducting, thus emergency warning lamp LD energising is lighted, imply that to hob the power that cutter 2 hobs bigger than normal, needs arouse attention, if run a period of time to have recovered again, then illustrate it is in the scope that can control, do not need to overhaul equipment.The situation of mechanical movement can well be judged by this scheme.

Preferably, described alarm unit A3 comprises the second comparing unit A31, the second reference voltage unit A32 and the second performance element A33; Described second reference voltage unit A32 is in order to produce the second voltage signal; Described second comparing unit A31 is coupled to pressure sensor A1 and the second reference voltage unit A32, in order to receive detection signal and the second voltage signal respectively, and exports the second drive singal; Described second performance element A33 is coupled to the second comparing unit A31 in order to receive the second drive singal and to respond the second drive singal to cut off the power supply of drive motors 5.

Second comparing unit A31 and the first comparing unit A21; second reference voltage unit A32 is consistent with the mentality of designing of the first reference voltage unit A22; second comparing unit A31 adopts comparator LM2; second reference voltage unit A32 adopts potentiometer Rp2; the magnitude of voltage that the magnitude of voltage of this setting sets than potentiometer Rp1 is large; therefore; what set as the pressure ratio potentiometer Rp1 detected wants high; and than potentiometer Rp2 setting also high time; explanation hobs cutter 2 closely can by adhesive tape cutting; need shut down and safeguard, inform staff.

Second performance element A33 comprises the second triode Q2 and normally closed relay K, and the base stage of described second triode Q2 is coupled to the output of the second comparing unit A31, and colelctor electrode is coupled to coil one end of normally closed relay K, grounded emitter; Another termination power of the coil of described normally closed relay K, the normally closed switch of described normally closed relay K is coupled between drive motors 5 and power supply.The coil of normally closed relay K is also parallel with active buzzer LB.

By conducting second triode Q2, active buzzer LB and normally closed relay K is energized simultaneously, makes active buzzer LB can sounding alarm, the normally closed switch of normally closed relay K disconnects simultaneously, cuts off the power supply of drive motors 5, whole equipment is quit work.

By this scheme, make equipment more safe and reliable, run more stable, it is more convenient to use.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
