The utility model can arbitrarily preset the number of the continuous bags to be cut through the count setting device, has the advantages of safe operation and convenient installation, and can carry out technological transformation on the existing packaging equipment for small bags.

Description

Quantitatively connect the bag cutter sweep

Technical field

The utility model relates to a kind of bag cutter sweep that quantitatively connects, and is particularly useful for pouch-packaged equipment, counts when packaging bag being connected the bag cutting, cuts off when numerical value reaches setting value again.

Background technology

At present, all pouch-packaged equipment is for the cutting of packaging bag, or adopts continuous dotted line cutting, or adopts independent single bag cutting, is difficult to realize quantitative company's bag cutting.If company's bag cutting that the client need be quantitative, the operative employee just must carry out artificial counting to the packaging bag that connects after bag cuts, and could case behind the tear fracture, both loses time like this, is easy to generate error again, influences quality.And at present great majority use producers, often all are that an operative employee operates an equipment, or even many, like this since, counting, the work of casing just are difficult to finish simultaneously.The most important thing is that the operative employee also must finish these unnecessary work when operating machines, certainly will have certain accident potential.

The utility model content

The purpose of this utility model is the above-mentioned deficiency at prior art, provides a kind of safe and reliable, intelligence quantitatively to connect the bag cutter sweep easily.This device can be realized quantitatively connecting of packaging bag wrapped cutting, greatly reduces operative employee's working strength.

To achieve these goals, the bag cutter sweep that quantitatively connects that the utility model proposes is made up of counting setting apparatus, PLC, electromagnetic valve, cylinder and cutter transfer device, its innovative point is constituting of cutter transfer device: cylinder push-rod and swinging block are hinged, swinging block and upper and lower push pedal are fixed on fixedly on the cutter shaft, dotted line cutter and the side that fixedly cutter are used, the extension spring tension abuts against upper and lower push pedal side by side down, rotary cutter is fixed in and rotates on the cutter shaft.

Above-mentioned cylinder push-rod of the present utility model is preferably hinged by cylinder joint and swinging block.

In addition, the utility model preferably is provided with upper and lower tool rest in addition, with the guiding dotted line cutter and fixedly the cutter horizontal displacement move.

With respect to prior art, the bag cutter sweep that quantitatively connects of the present utility model gives signal in PLC when the counting setting apparatus reaches preset value, PLC signals to electromagnetic valve, the advancing or retreat of solenoid control cylinder push-rod, thereby driving fixedly, cutter shaft rotates counterclockwise or clockwise rotates, the final conversion that realizes cutter reaches the purpose that quantitatively connects the bag cutting.The utility model can the company of realization wrap any setting of cutting quantity, can satisfy different clients' different requirements, has improved client's self the market competitiveness when increasing work efficiency.The utility model is safe and reliable, and is easy for installation, can undergo technological transformation to existing equipment.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1, Fig. 2, shown in Figure 3, the utility model one preferred embodiment provides quantitatively connects the bag cutter sweep, by the counting setting apparatus, PLC, electromagnetic valve and cutter transfer device are formed, the cutter transfer device consists of: the cylinder push-rod 110 usefulness cylinder joints 109 of cylinder 106 are hinged with swinging block 108, swinging block 108 and last, following push pedal 114,302 usefulness bolts 112 are fixed on fixedly on the cutter shaft 115, dotted line cutter 111 and fixedly cutter 303 use, following extension spring 113,304 tensions abut against side by side, following push pedal 114,302 side, on, following tool rest 117,305 usefulness bolts 116 are fixing, guiding dotted line cutter 111 and fixedly the switching of cutter 303 move, rotary cutter 103 usefulness bolts 102 are fixed in and rotate on the cutter shaft 101, rotate 103 rotations of cutter shaft 101 driven rotary cutter, cutting packaging bag 301.

Transmit control signal to electromagnetic valve by counting setting apparatus and PLC, 106 actions of solenoid control cylinder, cylinder push-rod 110 drives fixedly cutter shaft 115 rotations by swinging block 108, fixedly cutter shaft 115 drives upper and lower push pedal 114,302 actions simultaneously, thereby promote dotted line cutter 111 or fixing cutter 303, finally realize the cutter conversion.

Below in conjunction with description of drawings course of action of the present utility model.

As Fig. 2, Fig. 3, shown in Figure 4, when beginning to move, earlier according to the quantity that connects bag cutting setup parameter on the counting setting apparatus, PLC gives the electromagnetic valve signal, electromagnetic valve is by 105 ventilations of backhaul tracheae, cylinder push-rod 110 drive swinging blocks 108 and fixedly cutter shaft 115 cws forward backhaul position 202 to, promptly reach dotted line cutting work station as shown in Figure 4, push pedal 114 promotes dotted line cutter 111 last on this moment, following tool rest 117, move forward under 305 the guiding, fixedly cutter 303 move under the effect of following extension spring 304 backward, dotted line cutter 111 forms the dotted line cut state with the rotary cutter 103 that cutting axle drive shaft 104 drives, dotted line cutting packaging bag 301;

When the counting setting apparatus reaches preset value, signal to PLC, PLC notice electromagnetic valve is by 107 ventilations of rise tracheae, cylinder push-rod 110 drive swinging blocks 108 and fixedly cutter shaft 115 conter clockwises forward rise position 201 to, promptly reach cut-out station as shown in Figure 4, following push pedal 302 promotes fixedly, and cutter 303 move forward under the guiding of upper and lower tool rest 117,305, dotted line cutter 111 moves under the effect of last extension spring 113 backward, fixedly cutter 303 form dissengaged positions with the rotary cutter 103 that cutting axle drive shaft 104 drives, and cut off packaging bag 301;

Cut off back counting setting apparatus return-to-zero, counting promptly returns the dotted line cut state again again, circulates so repeatedly, realizes quantitatively connecting the purpose of bag cutting.
