Abstract
The invention discloses a rotary bag cutting device. The rotary bag cutting device comprises a machine frame and a synchronous cutting knife mechanism rotatably connected with the machine frame. The synchronous cutting knife mechanism comprises a cutting knife and a rotary cutter body, wherein the cutting knife periodically makes contact with the surface of a belt of a belt conveying mechanism, and the rotary cutter body is connected with a belt wheel of the belt conveying mechanism through the belt. The cutting knife is fixedly connected with the rotary cutter body. By the adoption of the rotary bag cutting device, formed zippered bags can be cut off continuously; in addition, by the adoption of the conversion of circumferential movement and intermittent movement, the impact force and abrasion of mechanical parts are reduced, and the bag cutting efficiency can be improved.
Description
Technical field
The present invention relates to zippered bag manufacturing equipment field, be specifically related to a kind of swinging and cut bagging apparatus.
Background technology
Often zippered bag can be used in packaging for foodstuff.The mode that the zippered bag of current use commonly uses punching press is carried out envelope and cuts bag, when sealing or notching device moves back and forth at a high speed punching press envelope up and down or to cut bag, the zippered bag that belt transmission mechanism send the type of making cannot be continued through, and due to machine components itself assemblage gap long-time move back and forth at a high speed after can wear and tear and become large, make to seal or notching device stroke up and down reciprocatingly and sealing or to cut bag time strength and the time unstable, so make the quality of zippered bag and the limited speed of bag, long term accumulation, makes bag inefficiency.
Summary of the invention
The invention is intended to provide a kind of swinging to cut bagging apparatus, can improve and cut a bag efficiency.
Base case of the present invention is: a kind of swinging cuts bagging apparatus, the synchronous cutter mechanism comprising frame and connect with gantry rotation, synchronous cutter mechanism comprises and the cutting knife of the belt surface periodic contact of belt transmission mechanism and the revolution cutter hub that is connected with the pulley belt of belt transmission mechanism, and cutting knife is fixedly connected with revolution cutter hub.
Cutting knife is fixedly mounted on and turns round on cutter hub and together rotate with revolution cutter hub.Drive revolution cutter hub to rotate the simplification achieved synchronous cutter mechanism by the belt pulley of original belt transmission mechanism, and it is synchronous with belt transmission mechanism to be easy to flying knife physical efficiency.And turn round cutter hub required time that rotates a circle and just in time can cut off cycle time of shaping zippered bag as one, realize the periodic intervals action that cutting knife cuts off shaping zippered bag.When cutting knife periodically contacts with the belt surface of belt transmission mechanism, just can by the cut-out one by one of shaping zippered bag.A bag mode is cut compared with original, use this device can the shaping zippered bag of successional cut-out, and this device adopts is the conversion of circular motion and intermittent movement, reduce impulsive force and the wearing and tearing of machine components itself, compare existing notching device motion mode up and down reciprocatingly, the arrangement increases and cut a bag efficiency, also reduce the loss of machinery itself.
Prioritization scheme one: as the further optimization to base case, cutting knife and balancing weight are connected on revolution cutter hub.Cutting knife and balancing weight are connected to and turn round on cutter hub, are convenient to installation and removal cutting knife and revolving body, also facilitate the processing of part.
Prioritization scheme two: as the further optimization to prioritization scheme one, synchronous cutter mechanism also comprises the balancing weight be fixedly connected on revolution cutter hub, and balancing weight and cutting knife are positioned at the side of turning round cutter hub simultaneously and angle is less than 90 °.The object arranging breeding block is in the process that balancing weight rotates at wraparound rotor body, the gravitional force that one larger can be provided in the process declined, and the gravitional force that balancing weight provides increases the instantaneous velocity of cutting knife in certain degree, instantaneous velocity when making cutting knife be belt contacts improves, reduce belt and cut off the buffering consumption of power to cutting knife, contributing to cutting knife like this can unusual the cutting off shaping zippered bag of fast powerful.
Prioritization scheme three: as the further optimization to prioritization scheme two, cutting knife and balancing weight are 45 ° turning round the angle on cutter hub.When cutting knife is positioned at lowest part and the belt contacts of belt transmission mechanism, and now with cutting knife turn round the balancing weight in 45 ° of angles on cutter hub be supplied to cutting knife speed reach a peak value, and cutting knife cuts off the instantaneous velocity that the most important factor of shaping zippered bag is exactly cutting knife and belt contacts, thus by such arrange can more effective time cutting knife by shaping Zipper-cutting.

Fig. 2 is revolution cutter hub and the cutter structure schematic diagram that a kind of swinging of the present invention cuts bagging apparatus embodiment.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation.It should be noted that at this, the explanation for these embodiments understands the present invention for helping, but does not form limitation of the invention.
Reference numeral in Figure of description comprises: belt transmission mechanism 1, shaping zippered bag 2, balancing weight 3, revolution cutter hub 4, cutting knife 5, frame 6, belt 7, belt pulley 8, groove 41.
A kind of swinging cuts bagging apparatus, and as shown in Figure 1, shaping zippered bag is placed on belt 7 transmission mechanism 1 and is continuously carried forward.Be provided with synchronous cutter mechanism above the belt of belt conveyor 1, synchronous cutter mechanism comprises revolution cutter hub 4, cutting knife 5, balancing weight 3.Revolution cutter hub 4 is rotationally connected with frame 6, and revolution cutter hub 4 is connected by belt with the belt pulley of belt transmission mechanism 1, and like this, the belt pulley of belt transmission mechanism 1 also can drive revolution cutter hub 4 to rotate around frame 6 when rotated.As depicted in figs. 1 and 2, the periphery of revolution cutter hub 4 is provided with the groove 41 perpendicular to belt 7, groove 41 is for clamping cutting knife 5.When turning round cutter hub 4 and rotating, cutting knife 5 wraparound rotor body 4 moves in a circle, and when cutting knife 5 rotates to lowest part, shaping zippered bag cuts off by the blade of cutting knife 5, and cutting knife 5 is when other position, does not contact with shaping zippered bag.
In the present embodiment, the rotation status of cutting knife 5 is keys that shaping zippered bag 2 cuts off.As shown in Figure 1, the blade of cutting knife 5 protrudes revolving body.Because revolution cutter hub 4 rotates a circle need the time, so turn round the rotary speed of cutter hub 4 according to technological requirement adjustment, the cutting knife 5 be connected on revolution cutter hub 4 just can cutting off shaping zippered bag 2 according to the length cycles of shaping zippered bag 2 one by one.In the present embodiment, revolution cutter hub 4 is also provided with balancing weight 3, balancing weight 3 is also connected on revolution cutter hub 4, and cutting knife 5 and balancing weight 3 are 45 ° turning round the angle on cutter hub 4.As shown in Figure 1, when cutting knife 5 is positioned at lowest part, balancing weight 3 will be supplied to revolution cutter hub 4 one gravitional force, and gravitional force makes cutting knife 5 have larger instantaneous velocity, and formal this instantaneous velocity can make cutting knife 5 be cut off by shaping zippered bag 2 very fast.Certainly, balancing weight 3 and cutting knife 5 might not be 45 ° turning round the angle on cutter hub 4, as long as balancing weight 3 and cutting knife 5 are positioned at the side of turn round cutter hub 4 and angle is less than 90 ° simultaneously, balancing weight 3 can be made to be supplied to and to turn round the gravitional force that cutter hub 4 one can produce advantageous effect.
