Abstract

The utility model discloses a rotary blanking mechanism which is applied to a full-automatic bag-feeding packing machine. The rotary blanking mechanism comprises a hopper (1) and a supporting plate (4), wherein the lower part of the hopper is in an angle-free hollow cylindrical shape (5), and a rotor gear (3) is arranged in the supporting plate and is at the periphery of the middle part of the hopper. The rotor gear is connected with a motor (13) through a middle connecting assembly, and an inner rotor (2) is arranged in the rotor gear and extends into the lower part of the hopper. The angle-free hollow cylindrical lower part of the hopper extends into a bag mouth of a packing bag, the rotor gear is driven by the motor to cause the inner rotor to rotate, the lower part of the hopper becomes a whole hollow cylindrical shape from the original angle-free hollow cylindrical shape, and then the hopper conducts blanking for materials in the packing bag, so that the large-scale hopper can conduct successful and fast blanking for large-particle materials and block materials. Therefore the rotary blanking mechanism brings convenience for blanking, the packing quality of the packing machine is ensured, and the rotary blanking mechanism has significant progress of technology.

Description

Rotary cutting agency

One, technical field

The present invention relates to a kind of bag-feeding-type automatic packaging unit that can pack automatically graininess, bulk, slurry shape or liquid-state materials such as candy, seed, medicine, beverages, specifically relate to a kind of cutting agency that is applied to bag-feeding-type automatic packaging unit.

Two, background technology

At present; The employed packaging bag of bag-feeding-type automatic packaging unit has coventional type four banding bags, support oneself bag, insert edge bag etc.; Through carrying out to bag, folder bag to this packaging bag (seal on former three limits, on one side only need the upper shed of opening is sealed), open (open bag on comprising, open bag down), filling successively, sealing, be shaped into the output operation and accomplish the packing of required material.Wherein cutting agency be in packaging bag through hopper to material carry, filling because the sack opening degree of packaging bag is limited, be difficult to put in the packing sack and blanking smoothly (material can spread bag outward) like the excessive then hopper outlet of hopper specification; Can not enter into packaging bag smoothly fast like the too small then material of hopper specification, thereby make troubles for the blanking of material (particularly bulky grain shape, lump material).

Three, summary of the invention

The objective of the invention is to overcome above-mentioned deficiency, also can realize smoothly the rotary cutting agency of blanking fast bulky grain shape, lump material and provide a kind of sack to be in common open mode in packaging bag.

The object of the invention is realized through following technical scheme: a kind of rotary cutting agency; Comprise hopper, back plate; Described hopper bottom is the unfilled corner hollow cylinder; In said back plate and at peripheral place, hopper middle part, the rotor gear is housed, this rotor gear links to each other with motor through intermediate connecting component; In described rotor gear, interior rotor is housed, and should extends in the bottom of hopper by interior rotor.

After adopting structure of the present invention; The unfilled corner hollow cylinder bottom that is by hopper extend in the sack of packaging bag earlier; Rotor rotation in being made by driven by motor rotor gear again formed whole hollow cylinder (being that former unfilled corner part is enriched by rotor in postrotational) with the bottom of hopper by being the unfilled corner hollow cylinder originally, and blanking carried out to material by hopper in the back in packaging bag; Even the hopper of big specification to bulky grain shape, lump material can both be well on, blanking fast; Thereby brought facility to blanking, guaranteed the packaging quality of wrapping machine, had significant technological advance.

Four, description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is made further detailed description.

Fig. 1 is the structural representation of rotary cutting agency of the present invention and installation thereof.

Scheme drawing when Fig. 2 forwards the unfilled corner place, bottom of hopper to for the interior rotor among Fig. 1.

Five, the specific embodiment

Can know with reference to Fig. 1, Fig. 2; The present invention is applied to the rotary cutting agency of bag-feeding-type automatic packaging unit; Comprise hopper 1, back plate 4; Described hopper 1 bottom is unfilled corner hollow cylinder 5 (also can be described as outer stator), in said back plate 4 and at place, periphery, hopper 1 middle part, rotor gear 3 is housed, and this rotor gear 3 links to each other with motor 13 through intermediate connecting component; Rotor 2 in described rotor gear 3, being equipped with, and should in rotor 2 (part) extend to (promptly the bottom of interior rotor and the bottom of hopper form overlapping) in the bottom of hopper 1.Said hopper 1 is that hopper body, middle part promptly rotatable interior rotor, bottom are that fixed outer stator three parts are split typely to constitute by its top; Described hopper 1 bottom is unfilled corner hollow cylinder 5 and is the semicircle hollow cylinder, conveniently to install and use.

Wherein, Described intermediate connecting component (being contained in the back plate 4) is made up of the gear bearing pin 8 in carrier gear 9, the carrier gear, motor gear 12; This motor gear 12 is contained in the rotating shaft 11 of motor 13; Carrier gear 9 is meshed with rotor gear 3, can be two covers owing to assembling this carrier gear 9 of reason and gear bearing pin 8, and motor 13 is contained under the back plate; Described back plate 4 is contained on the body 7 of this wrapping machine through two groups of guide shafts 15 and the outer guide pin bushing 16 of guide shaft; On between two guide shafts 15 horizontal stripe 14 is housed; On the body 7 of this wrapping machine and between guide shaft 15, locate to be equipped with cylinder 6, the piston rod 10 of cylinder 6 links to each other with horizontal stripe 14.

Baiting method like described rotary cutting agency gained is: at first, naturally, conveniently extend into the sack interior (even the hopper specification greatly also can be accomplished) of packaging bag because the bottom of hopper is unfilled corner hollow cylinder (as shown in Figure 1); Then; Electric motor starting also drives the rotor gear through intermediate connecting component (motor gear, carrier gear) and makes interior rotor rotation; Thereby the bottom of hopper was formed whole hollow cylinder by being the unfilled corner hollow cylinder originally; Be that its former unfilled corner part is enriched (as shown in Figure 2) by rotor in postrotational, motor promptly quits work; Then, in packaging bag, material is carried out blanking by hopper, even the hopper of big specification to bulky grain shape, lump material can both realize smoothly, quick blanking; After treating that the blanking filling is accomplished; Motor start once more and in driving rotor forward in the bottom of hopper that (promptly the bottom of interior rotor hides, overlaps onto in the bottom of hopper to; As shown in Figure 1); Make the bottom of hopper return to the original unfilled corner hollow cylinder that is, motor promptly quits work, to wait for conveying blanking action next time.Can also drive the oscilaltion that horizontal stripe is realized back plate and hopper through the work of cylinder.
