Description

[0003] In the prior art, the handle feeding sprocket transmission unit is often conveyed by three transmission chains, with the same transmission ratio and the same rotational speed of the driving sprocket. Only a single-sided pusher is used to push the handle paper sheets, without a paper sheet guide bar, and only two groups of simple pressure rollers are closely attached to the guide rollers to stick the handle to the surface of the paper bag, without a handle rope avoidance structure. On the one hand, this method does not provide sufficient protection for the handle paper sheets and is prone to damage the paper sheets, especially the handle. On the other hand, it is easily caught by the machine and damaged, resulting in paper sheet jams in the machine and causing machine failures. Summary of the Invention:

[0019] In order to improve the stability of the hand-held paper sheet transmission and avoid the double push and the shear force of the belt, the second power sprocket and the third power sprocket have the same number of teeth, the second upper sprocket has 22 teeth, the upper chain has 66 sections, the first lower sprocket has 20 teeth, and the lower chain has 100 sections. Therefore, the linear speed of the second upper sprocket is greater than the linear speed of the first lower sprocket. At the same time, the linear speed of the guide roller is greater than the linear speed of the second upper sprocket. Therefore, the hand-held paper sheet can be quickly pulled away, thereby avoiding the hand-held paper sheet being hooked by the machine and causing damage.

[0020] In order to improve the transmission efficiency and achieve the best transmission effect, it is preferred that one double push pin is connected to every 22 sections on the upper chain, and one push pin is connected to every 20 sections on the lower chain.

[0043] As Figure 1 and Figures 4 - 5As shown, the material guiding plate assembly 5 is arranged between the upper transmission mechanism 3 and the lower transmission mechanism 4, and includes a square support block 51, a material guiding bottom plate 52, a right material guiding plate 53, a left material guiding plate 54, a paper sheet guiding bar 55, a guiding block 56, a fixing block 57, and a fixing block shaft 58. The square support block 51 is connected to the wall panel 1, the material guiding bottom plate 52 is connected to the square support block 51 through a support block 59, the right material guiding plate 53 is arranged on the square support block 51, the left material guiding plate 54 is connected to the wall panel 1, the paper sheet guiding bar 55 is arranged between the upper chain 324 and the material guiding bottom plate 52 and has a certain gap with the material guiding bottom plate 52 to allow the passage of paper sheets, the fixing block shaft 58 is connected to the wall panel 1, the guiding block 56 is sleeved on the fixing block shaft 58 and fixed by the fixing block 57, and the lower plane of the guiding block 56 contacts the inner ring of the upper chain 324.

[0044] When using this handle paper sheet transmission mechanism to transmit handle paper sheets, the handle paper sheets are fed in from the paper sheet guiding bar 55. In the power sprocket mechanism 2, the first power sprocket 21 drives the power chain 26 to operate. The power chain 26 drives the second power sprocket 22 to rotate forward and the third power sprocket 23 to rotate in reverse. Since the second power sprocket 22 connected to the first transmission shaft 6 and the third power sprocket 23 connected to the second transmission shaft 7 have the same number of teeth and opposite rotation directions, the first transmission shaft 6 and the second transmission shaft 7 have the same rotational speed and opposite rotation directions.

[0045] The first transmission shaft 6 drives the first lower sprocket 411 to rotate. The first lower sprocket 411 has 20 teeth, the lower chain 414 has 100 links, and a push pin 415 is installed on every 20th link of the lower chain 414. The sprocket 411 passes through 20 links of the chain in one revolution and pushes one handle paper sheet; the second transmission shaft 7 drives the second upper sprocket 322 to rotate. The second upper sprocket 322 has 22 teeth, the upper chain 324 has 66 links, and a double push pin 325 is installed on every 22nd link of the upper chain 324. The second upper sprocket 322 passes through 22 links of the chain in one revolution and pushes one handle paper sheet. Although the first lower sprocket 411 and the second upper sprocket 322 have the same rotational speed, due to different numbers of teeth, their linear speeds are different. The linear speed of the upper chain 324 is greater than that of the lower chain 414. When the handle paper sheet is moved to the first pulley 311 by the push pin 415, the double push pin 325 on the upper chain 324 can accelerate its backward movement to avoid damage to the handle paper sheet when the push pin 415 rotates around the first lower sprocket 411.

[0046] When the handle piece of paper is conveyed by the circular belt 317 to the pinch roller 3161, it is pressed by the pinch roller 3161 and adhered to the paper on the guide roller 9. After the double push rod 325 pushes the handle piece of paper from the first pulley 311 to the guide roller 9, since the linear velocity of the rotation of the guide roller 9 is greater than the linear velocity of the second upper sprocket 322, the handle piece of paper can be taken away at an accelerated speed and continue to be conveyed downward under the traction of the tank wheel 8, so that it quickly disengages from the double push rod 325, avoiding the shear force between the double push rod 325 and the circular belt 317.

[0047] During the conveyance of the handle piece of paper, the second pulley 313 is always pressed tightly on the circular belt 317, the screw bearing 333 is always closely attached to the cam working surface of the cam 331. When the cam 331 rotates one circle, the second upper sprocket 322 rotates one circle, and the double push rod 325 pushes one handle piece of paper. Under the action of the cam 331, the second pulley 313 is lifted once, which can effectively avoid the handle rope on the handle piece of paper.
