It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.

As shown in fig. 1 to 5, a feeding mechanism of a bag making machine comprises a workbench 1, a straight rod 2 is connected inside the workbench 1, two ends of the straight rod 2 are symmetrically provided with two support frames 19, and the support frames 19 can support raw materials. An inserting rod 23 is arranged above the supporting frame 19, two rotating shafts 24 are arranged outside the inserting rod 23 in a penetrating mode, a user inserts the rotating shafts 24 into the raw materials, and then inserts the inserting rod 23 into the rotating shafts 24, so that the raw materials are fixed.

Two cylinders 20 are symmetrically and fixedly arranged on the workbench 1, two convex rods 21 are symmetrically and fixedly arranged on two sides of the two support frames 19, levers of the two cylinders 20 are respectively hinged with the two convex rods 21, and when the two cylinders 20 are started, the cylinder rods of the cylinders 20 extend to push the two convex rods 21 to rotate downwards around the hinged parts. The support frames 19 are respectively hinged with two ends of the straight rod 2, and when the convex rod 21 rotates downwards around the hinged part, the two support frames 19 also rotate downwards around the hinged part, so that the two support frames 19 are slowly close to the lower end surface of the workbench 1.

One side of two support frames 19 all is equipped with the draw-in groove, and the draw-in groove can be with the both ends card of inserted bar 23 on support frame 19, and when support frame 19 was close to the lower terminal surface of workstation 1, the user lifted the raw materials that has fixed, made the both ends card of inserted bar 23 in the draw-in groove to fix the raw materials on two support frames 19. Be connected with support column 22 between the support frame 19, support column 22 can increase the fastness between two support frames 19, prevents that the gravity of raw materials from making two support frames 19 crooked, and later the jar pole of cylinder 20 is retracted, and the jar pole can drive support frame 19 round articulated department upward movement to rise the raw materials slowly, make raw materials and ground separation.

The top of workstation 1 is equipped with backup pad 4, when the raw materials is sufficient, the diameter of raw materials is great, support frame 19 drives the raw materials and rises the messenger, the raw materials can push up runner 17 upward movement, thereby make backup pad 4 be close to one side rebound of runner 17, one side of straight-bar 2 has set firmly bracing piece 3, and bracing piece 3 is articulated with backup pad 4, when runner 17 upward movement is moved in the raw materials top, one side that backup pad 4 is close to runner 17 can rotate upward movement round articulated department, thereby one side that runner 17 was kept away from to messenger backup pad 4 rotates downward movement round articulated department.

One side that the driver box 13 was kept away from to backup pad 4 is equipped with push rod 12, and push rod 12 and the one end that connecting rod 8 was kept away from to connecting rod four 11 are articulated, and when one side that runner 17 was kept away from to backup pad 4 rotated the downstream around articulated department, one side that runner 17 was kept away from to backup pad 4 can drive push rod 12 and rotate around articulated department, makes the angle between backup pad 4 and the push rod 12 reduce gradually to pulling push rod 12 moves down. One end of the push rod 12, which is far away from the support plate 4, is provided with a fourth connecting rod 11, the fourth connecting rod 11 is hinged to the push rod 12, the other end of the fourth connecting rod 11 is provided with a first connecting rod 8, the fourth connecting rod 11 is hinged to the first connecting rod 8, two sides of the straight rod 2 are respectively provided with a second connecting rod 9 and a third connecting rod 10, the second connecting rod 9 and the third connecting rod 10 are both hinged to the straight rod 2, and one sides, far away from the straight rod 2, of the second connecting rod 9 and the third connecting rod 10. When the push rod 12 moves downwards, the fourth connecting rod 11 is driven to rotate towards one side close to the second connecting rod 9, so that the second connecting rod 9 is driven to swing back and forth in a small range around the hinge joint of the straight rod 2, the third connecting rod 10 rotates towards the side close to the second connecting rod 9 around the hinge joint of the straight rod 2, one end, close to the third connecting rod 10, of the first connecting rod 8 rotates downwards, and finally one end, far away from the push block, of the first connecting rod 8 moves upwards.

And when the first connecting rod 8 moves upwards, the angle between the first connecting rod 8 and the sliding rod 7 is increased, so that the sliding rod 7 moves upwards. The upper end face of the inside of the workbench 1 is fixedly provided with a sliding barrel 5, the bottom of the sliding barrel 5 is fixedly provided with a spring 6, a sliding rod 7 penetrates through the sliding barrel 5 and is fixedly connected with one end, far away from the bottom of the sliding barrel 5, of the spring 6, when the sliding rod 7 moves upwards, the sliding rod 7 can push the spring 6, the spring 6 is extruded, and therefore the spring 6 generates elastic force.

One side of the supporting plate 4 is fixedly provided with a driving box 13, a worm 14 is arranged in the driving box 13, the outer wall of the driving box 13 is fixedly provided with a motor 15, and an output shaft of the motor 15 penetrates through the driving box 13 and is fixedly connected with the worm 14. When the motor 15 starts, the motor 15 rotates to drive the worm 14 to rotate, the worm wheel 16 is arranged in the drive box 13, the worm 14 rotates to drive the worm wheel 16 to rotate, the rotating wheel 17 is arranged on one side of the drive box 13, the rotating drum 18 is fixedly arranged in the rotating wheel 17, the rotating drum 18 is T-shaped, and one end, far away from the rotating wheel 17, of the rotating drum 18 penetrates through the drive box 13 and is fixedly connected with the worm wheel 16. When worm wheel 16 rotates, can drive rotary drum 18 and rotate to drive runner 17 and rotate, support frame 19 rises to raw materials and runner 17 surface laminating, and when runner 17 rotated, can drive the raw materials and take place relative rotation, and when the raw materials rotated, pivot 24 and raw materials kept the rotation of equidirectional, and pivot 24 rotated and can not drive inserted bar 23 and rotate, thereby made the raw materials evenly send out.

The surface of runner 17 is enclosed and is equipped with anti-abrasion circle 27, and the abrasionproof circle 27 is surperficial rough, and abrasionproof circle 27 is elastic, and abrasionproof circle 27 enables the frictional behavior increase between runner 17 and the raw materials, when the raw materials is sent out, guarantees not skid between runner 17 and the raw materials.

The bottom of the interior of the workbench 1 is connected with two long shafts 25, one sides of the two long shafts 25 are provided with rollers 26, the two long shafts 25 penetrate through the rollers 26, a user can enable the sent raw materials to pass through the two rollers 26, and the raw materials and the rollers 26 keep rotating relatively in the feeding process, so that the raw materials can keep flat in the sending process, and the raw materials are prevented from being folded and shrunk into a group.

When the raw materials constantly send out, the raw materials constantly reduces, thereby make the diameter of raw materials reduce gradually, because raw materials and runner 17 surface laminating, so one side that backup pad 4 is close to runner 17 can rotate round articulated department and move down gradually, thereby one side that runner 17 was kept away from to messenger backup pad 4 rotates round articulated department and moves up gradually, one side that runner 17 was kept away from to backup pad 4 can promote the ejector pad rebound, finally make one side that connecting rod 8 kept away from the ejector pad move down gradually, when connecting rod 8 moves down, can drive slide bar 7 and move down gradually, because the even promotion slide bar 7 of the elasticity of spring 6 moves down gradually, make runner 17 and raw materials surperficial pressure be in the homogeneous state, thereby the efficiency that the raw materials sent out has been improved.
