The beneficial effect of the invention
The invention provides a kind of packaging bag feedway, because at least one impeller is under the drive of transmission component, promotes packaging bag and carry forward; Before next packaging bag arrives, previous packaging bag has been pushed away the outlet that sealing is shaping, the phenomenon preventing two packaging bags mutually to clash into occurs, thus has stopped packaging bag and be out of shape because of shock.In addition, impeller promotes packaging bag from back to front to move, and can not occur that the imagination that packaging bag cannot be transmitted occurs because of skidding.
The invention provides a kind of packaging bag feedway because transmission component is symmetrically arranged sprocket drive, so the propelling thrust left-right balance of impeller, and chain sprocket drive friction and loss little, the transmission of power is stablized.
The invention provides a kind of packaging bag feedway, because there is width adjusting assembly and height adjustment assembly can carry out flexible according to the size of packaging bag with highly, expand the range of use of packaging bag feedway.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Fig. 1 is the front view of packaging bag feedway of the present invention.
Fig. 2 is the left view of packaging bag feedway of the present invention.
Fig. 3 is the birds-eye view of packaging bag feedway of the present invention.
Fig. 4 is the block diagram of packaging bag feedway of the present invention.
Packaging bag in the present embodiment is urine pants packaging bag W.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, packaging bag feedway comprises: support, platform T, drive division 10, transmission component 20, four impellers 30, width adjusting assembly 40 and height adjustment assemblies 50.
Packaging bag feedway is arranged on a support with equipment for forming package bag, and support is for supporting all parts of whole packaging bag feedway.Packaging bag feedway is in the rear side of equipment for forming package bag.Symmetrically arranged packaging bag forming backup plate 100 is just in the front end of packaging bag feedway.
Transmission component 20 comprises two groups of symmetrically arranged sprocket drives, is arranged on the both sides of packaging bag.Each sprocket drive comprises a drive sprocket 21, three driven sprockets 22 and a chain 23.Drive sprocket 21 and driven sprocket 22 are fixed on support, and chain 23 is enclosed within drive sprocket 21 and driven sprocket 22.A drive sprocket 21 and three driven sprockets 22 form four summits of a rectangle respectively, and chain 23 forms a rectangle.
Drive division 10 comprises drive motor 13, driving band 12 and transmission shaft 11.Drive motor 13 starts, and by driving band 12, drives transmission shaft 11 to rotate.Transmission shaft 11 is fixedly connected with two drive sprockets 21 respectively, transmission shaft 11 by transmission of power to drive sprocket 21.Drive sprocket 21 drives chain 23 and driven sprocket 22 to operate.Therefore, two chains 23, by the propulsive effort of drive division 10, make circulating motion.In the present embodiment, clockwise direction circular flow done by chain 23 (Fig. 4).
Certainly, drive division can adopt two drive motor synchronously to drive two sprocket wheels respectively.Although add the quantity of drive motor like this, be the reduction of driving band and transmission shaft parts, decrease the loss that drive disk assembly also just decreases propulsive effort, and structure be simple.
Impeller 30 is round bar, and its two ends are horizontally fixed on chain 23 respectively.Four impellers 30 are distributed on chain.
Fig. 5 is that the impeller of packaging bag feedway of the present invention is started working view.
Fig. 6 is that the impeller of packaging bag feedway of the present invention is finished the work view.
As shown in Figure 5 and Figure 6, impeller 30 rotates along with chain 23, and path of motion is rectangular.After impeller 30 is moved upwards up to highest level position, enter the movement of horizontal direction.Now, impeller 30 starts to enter mode of operation, and after urine pants packaging bag W-1 packaging bag forming backup plate 100 completes sizing, impeller 30 promotes urine pants packaging bag W-1 and moves to the right on platform T.Until after urine pants packaging bag W-1 is pushed away platform T, impeller 30 arrives right-most position, start along with chain 23 runs downwards.Now, next urine pants packaging bag W-2 completes molding procedure, waits for that an other impeller 30 carries out promotion conveying operation.
Impeller quantity in the present embodiment is 4, certainly can arrange other quantity, mainly according to the setting of urine pants packaging bag W speed of transmission.
Width adjusting assembly 40 is arranged on the both sides of platform T, and the width of adjustment kit pack conveying, comprises the width positioning plate 41 and width adjusting handle 42 that are symmetricly set on packaging bag both sides.Width positioning plate 41 is arranged on the both sides of packaging bag transport path.Width adjusting handle 42 regulates the width that can change between two pieces of width positioning plates 41, to adapt to the size of Different Package bag, plays directional tagging, makes packaging bag can not offset direction in the process of conveying, moves according to predetermined throughput direction.
Height adjustment assembly 50 is lifter, is arranged on the below of platform T.Can be heightened by rotation and lifting device handle or be turned down lifter, platform T also rises along with lifter or declines, to reach the height of adjustment kit pack conveying.The height of packaging bag is also different, height adjustment assembly 50 can adjustment kit pack conveying time height, make impeller be in packaging bag height half position, the level attitude residing for namely packaging bag center of gravity.Like this, impeller can promote packaging bag reposefully.Certainly, some packaging bag may weight inequality distribute, and can adjust the position that impeller promotes packaging bag, make packaging bag course of conveying more smooth and easy according to actual conditions.
The working process of packaging bag feedway:
First, rotating width adjusting handle regulates the distance of two pieces of width positioning plates to be applicable to the size of needs transport package; Rotation and lifting device handle regulates the height of lifter to make the extreme higher position of packaging bag center-of-gravity position and impeller be in sustained height.
Start drive motor, by the transmission of driving band power, drive drive axis.Transmission shaft drives two drive sprockets to rotate, and drive sprocket drives driven sprocket and chain to rotate clockwise.The motion track being fixed on four impellers on chain is exactly the rectangle that chain is formed.
After the packaged bag forming backup plate of packaging bag W-1 completes molding procedure, when an impeller moves to the position of meeting packaging bag W-1, start driven forward W-1.Along with this impeller of chain promotes packaging bag W-1 always, until packaging bag W-1 leaves platform T.Now, packaging bag W-1 completes and delivers into next operation, and this impeller starts downward operation.
Next packaging bag W-2 also completes molding procedure, and another root impeller also moves up, and enters work area.Packaging bag feedway is exactly go round and begin again like this, cyclically carry out conveying operation.
