Description

The adjustable synchronous transmission device of continuous capper

The utility model relates to the device that a kind of packaging for foodstuff is sealed.

At present, known capper can be divided into two kinds of discontinuous formula and continous ways, discontinuous formula capper there is no the transmission device of cramping conveying and packaging bag, so need to borrow artificial time and effort consuming ground by the bag pressing operation, to seal its packing sack, it not only greatly reduces the efficient of packing bag, and can influence the packing quality of packaging bag, system borrows two groups of Power trains as for the continous way capper, with difference cramping heat sealed package sack and carrying conveying and packaging bag, these two groups of Power trains then need to borrow adjusts synchrodrive speed exactly, just can reach expection continuously packing seal the processing operation; Do not have synchronizing controls between two groups of Power trains of known continuous capper, so the load-transfer device speed of carrier package material then often is stranded the difference of carrying weight of material and is changed to some extent, and then cause packaging bag seal the cramping delivery speed with the carrying bag load-transfer device speed different, its not only can make packaging bag bag inclination distortion and even can have a strong impact on follow-up continuous packaging seal operation, for known continuous capper drawback in the use, then await being studied improvement.

In view of this, the purpose of this utility model provides a kind of adjustable synchronous transmission device of continuous capper, and the rotating speed of transmission shaft is adjusted, and and then makes the load-transfer device delivery speed of capper be obtained synchronous adjustment.

The purpose of this utility model is achieved in that a kind of adjustable synchronous transmission device of continuous capper comprises load-transfer device, the support bogie side frame, support and the transmission device of forming by chain and V-shape belt by setting thereof, wherein, chain is driven by a drive sprocket, and this drive sprocket is by a motor direct drive, two sprocket wheels that chain is with synchronously reach the sprocket wheel with the coaxial pivot joint of belt pulley, it is characterized in that: the belt train is borrowed V-shape belt to drive a belt pulley synchronously and is reached by last, the belt pulley that following disk body constitutes, and the outside of V-shape belt and compress an idle pulley, and by last, the belt pulley that following disk body constitutes is articulated on the axle bed of support bogie side frame, and disk body is mounted on the transmission shaft down, last disk body then slides on the transmission shaft and unitary rotation, goes up the disk body end face in addition and also is provided with an adjustment knob and a dowel bolt.

The transmission shaft of above-mentioned upper and lower disk body and seal between the transmission shaft of load-transfer device and be provided with a pair of umbrella shape helical wheel.

Owing to adopt such scheme: make not only that packaging bag enclosing is smooth and easy to carry out, and improved packaging bag enclosing efficient and quality.

Below in conjunction with drawings and Examples the utility model is further specified.

Shown in Fig. 1-4, present embodiment ties up in the support 10 transmission device of being made up of a chain 25 and a V-shape belt 35 is set, wherein chain 25 is by 20 transmissions of a drive sprocket, this drive sprocket 20 then is a motor direct drive, 25 synchrodrive of sprocket wheel, two sprocket wheels 21 in addition, 23 reach and the belt pulley 30 coaxial sprocket wheel (not shown) that are pivoted, make drive sprocket 20, two sprocket wheels 21,23 and belt pulley 30 be able to synchronous constant speed and rotate, as for, two sprocket wheels 21,23 is that clamping conveying mechanisms such as the roller of drive stand 10 bottom surfaces and steel band (belong to prior art, so will not give unnecessary details), the clamping conveying mechanism of this group roller and steel band then is a cramping packaging bag sack, and the mechanism that its heat-sealing and conveying are advanced; Continue it, belt pulley 30 be by this V-shape belt 35 with synchronous interlock one belt pulley 31 and by last, following disk body 42,43 belt pulleys that constituted, wherein by last, following disk body 42, the 43 belt train axles of being formed are articulated on the axle bed 46 of support bogie side frame 12, and this time disk body 43 be borrow one fixedly chain 431 and build-in in a transmission shaft 44, go up the inner diameter wall of disk body 42 in addition and hold and also have a keyhole 421, it is to keep supplying disk body 42 to be able to correspondence and to be slidingly located in transmission shaft 44 and to be the unitary rotation state, end face as for last disk body 42 then is provided with an adjustment knob 40 and a dowel bolt 41, when unscrewing dowel bolt 41, then can borrow turn to adjust knob 40, on adjusting, following disk body 42,43 axial spacing, because of this V-shape belt 35 is 37 the packing effect that is subjected to an idle pulley, so make V-shape belt 35 be able to packing, and drive by last, following disk body 42,43 belt pulleys of being formed, and then make transmission shaft 44 also be able to the umbrella shape bevel gear set 47 of synchrodrive lower end, 48, relend the transmission shaft 49 of interlock load-transfer device 50, reach synchronous drive load-transfer device 50 and rotate.

As Fig. 5, shown in 6, the latent structure of present embodiment is promptly borrowed on the belt pulley, following disk body 42,43 axial spacing adjustment, and then change on V-shape belt 35 and the belt pulley, following disk body 42, the radial distance in 43 axle center, under the identical transmission speed of V-shape belt 35, then can adjust in response to needs, following disk body 42,43 and the slewing rate of transmission shaft 44, so as to reaching the speed of synchronous adjustment load-transfer device 50 conveying and packaging materials, promptly when load-transfer device 50 causes delivery speed slow because of carrying heavier connection with wrapping of piece, then it obviously can't cooperate the cramping of packaging bag sack to seal speed, carry out and cause the packaging bag inclination and influence the packaging bag enclosing operation, at this moment, the operator can unscrew dowel bolt 41 earlier, and knob 40 is adjusted in the turn that makes progress simultaneously, can be subjected to the elasticity packing effect of idle pulley 37 because of V-shape belt 35, so V-shape belt 35 can strut and force, following disk body 42,43 axial spacing increases (as shown in Figure 6), and V-shape belt 35 is with last, following disk body 42, the radial spacing in 43 axle center also reduces relatively, relatively can make, following disk body 42,43 and the rotating speed of transmission shaft 44 increase, and increase the delivery speed of load-transfer device 50 so as to synchronous adjustment, and treat that the operator adjusts load-transfer device 50 and seals the cramping delivery speed when consistent, then can screw dowel bolt 41 and finish synchronous adjustment operation; Otherwise, when the delivery speed of load-transfer device 50 is very fast, then borrow to be screwed down and adjust knob 40, to adjust the axial spacing (as shown in Figure 5) that reduces upper and lower disk body 42,43, and then relatively can increase the radial spacing in V-shape belt 35 and upper and lower disk body 42,43 axle center, the rotating speed of upper and lower disk body 42,43 and transmission shaft 44 is reduced, and and then the delivery speed of load-transfer device 50 is slowed down synchronously, reach and adjust load-transfer device 50 and the speed of sealing the cramping conveying mechanism easily synchronously.
