Description

Technical Field

[0001] The invention relates to the technical field of paper conveying, in particular to a rubber roller assembly for automatic paper feeding. Background Art

[0002] Paper conveying requires the use of a rubber roller assembly, which is usually composed of an axle, a tire, and a roller surface. It is basically a cylindrical part. When using an automatic paper feeding device, the paper is placed on the surface of the rubber roller and is transported to the target location while rotating on the roller surface.

[0003] The patent with the patent announcement number CN214359187U relates to an automatic paper feeding mechanism for a double-sided machine, and relates to the field of machinery. The automatic paper feeding mechanism for a double-sided machine comprises a base, the upper surface of which is fixedly connected with a first side plate and a second side plate, the right side of the first side plate is provided with a movable groove, the left side of the second side plate is provided with a movable hole connected with the right side, the inside of the movable groove is movably connected with a movable shaft, the right end of the movable shaft is movably connected with the inside of the movable hole, and the surface of the movable shaft is fixedly connected with a roller. The automatic paper feeding mechanism for a double-sided machine, through the mutual cooperation between the scale, the lifting groove, the spring, the limit rod, the jack, the slot, the latch and the movable ring, can adjust the distance between the roller and the movable roller according to the thickness of the paper material to be fed, thereby completing the transportation of paper materials of different thicknesses, solving the problem that the automatic paper feeding mechanism for a double-sided machine is not easy to adjust the distance of the paper feeding mechanism, and thus cannot transport paper materials of different thicknesses.

[0004] In the above patent, the distance between the roller and the movable roller is adjusted according to the thickness of the paper material being fed through the mutual cooperation between the scale, lifting groove, spring, limit rod, jack, slot, pin and movable ring, thereby completing the transportation of paper materials of different thicknesses. However, when the paper moves onto the pulley, the friction between the paper and the pulley is insufficient, causing the starting end of the paper to detach from the conveying wheel, thereby affecting the effect of the conveying wheel driving the paper to move.

[0016] (III) Beneficial effects

[0017] The present invention provides a rubber roller assembly for automatic paper feeding, which has the following beneficial effects:

[0018] (1) The rubber roller assembly for automatic paper feeding drives the swing block to rotate through the electric push rod and the push rod, so that the swing plate drives the pressing wheel to fit on the conveying wheel, and the pressing wheel presses the paper to fit on the conveying wheel, thereby increasing the friction between the paper and the conveying wheel, preventing the starting end of the paper from separating from the conveying wheel, thereby affecting the effect of the conveying wheel driving the paper to move.

[0019] (2) The rubber roller assembly for automatic paper feeding can push the forked rod to push the sliding rod and the contact rod to move, so that the roller can push the paper to move forward and backward on the conveying wheel, thereby preventing the position of the paper on the conveying wheel from being offset and affecting the effect of the paper moving on the conveying wheel. At the same time, the fixed plate can push the trapezoidal block and the swing plate to move, so that the swing plate can drive the roller to intermittently separate from the paper, thereby preventing the roller from being pressed tightly and making it difficult for the paper to move forward and backward.

[0020] (3) The rubber roller assembly for automatic paper feeding generates static electricity on the surface of the friction rod by rubbing the friction rod on the surface of the paper. The static electricity on the surface of the friction rod can adsorb foreign matter adhering to the surface of the paper to prevent the foreign matter adsorbed by the paper from affecting subsequent production. At the same time, the triangular block pushes the sealing plate to move. When the sealing plate moves upward, negative pressure is generated at the bottom of the sealing plate, so that the suction frame absorbs foreign matter around the friction rod. When the moving rod moves, it drives the elastic rod and the impact block to move. When the impact block moves, it impacts the force-bearing block and the linkage rod, so that the linkage rod drives the shaking wheel to rotate. The vibration generated by the shaking wheel can improve the effect of separating foreign matter at the bottom of the paper from the paper. BRIEF DESCRIPTION OF THE DRAWINGS

A one-way valve 68 is fixedly arranged inside so that only air can be taken in through the pipeline. When the paper moves, it will rub against the friction rod 62, so that static electricity is generated on the surface of the friction rod 62. The static electricity on the surface of the friction rod 62 can adsorb foreign matter adhered to the paper, so that the sealing frame 64 can absorb dust from around the friction rod 62 through the pipeline and the air suction frame 63.

[0036] A cover plate 67 is fixedly installed at the bottom of the sealing plate 65, and a through hole is opened on the surface of the cover plate 67. An air intake frame 66 is fixedly installed at the bottom of the sealing frame 64, and an injection frame 69 is fixedly installed on the surface of the sealing frame 64. A conductive rod 5 is fixedly installed on the surface of the moving rod 610. A No. 3 spring sheet is arranged between the sealing plate 65 and the sealing frame 64, and the suction force can be increased through the cover plate 67.

A force block 74 is fixedly mounted on the surface of the linkage rod 73, and a volute spring is provided between the linkage rod 73 and the sealing frame 64.

[0038] During operation, one end of the paper is attached to the conveying wheel 2 on the left, and the electric push rod 35 drives the pushing rod 36 to move. When the pushing rod 36 contacts the swing block 32, the pushing rod 36 will push the swing block 32 to rotate downward.

When the protrusion 48 moves, it collides with the concave block 49, so that the protrusion 48 drives the arc spring piece 47, the movable plate 45 and the roller 46 to vibrate. The vibration generated by the roller 46 drives the paper to vibrate. At the same time, when the connecting plate 42 moves, it drives the fixed plate 410 to move. When the fixed plate 410 moves, it contacts the inclined surface of the trapezoidal block 411, so that the fixed plate 410 drives the trapezoidal block 411 to move, and the trapezoidal block 411 drives the swing plate 33 and the pressing wheel 34 to vibrate up and down with a small amplitude.

[0039] When the paper moves, it will rub against the friction rod 62, so that the surface of the friction rod 62 will generate static electricity. The static electricity on the surface of the friction rod 62 can adsorb foreign matter adhering to the paper. When the connecting plate 42 moves, it will drive the transmission rod 611 to move. When the transmission rod 611 moves, it will drive the bending rod 612 and the triangular block 613 to move.

When the sealing plate 65 moves upward, the bottom of the sealing plate 65 will be reset when it moves downward, and the air inlet frame 66 will be sealed by the cover plate 67, so that the negative pressure at the bottom of the sealing plate 65 will gradually increase, so that when the through hole on the cover plate 67 is connected with the air inlet frame 66, the seal of the air inlet frame 66 will be released, so that the sealing frame 64 will absorb dust from the surrounding of the friction rod 62 through the pipeline and the suction frame 63, and at the same time, when the moving rod 610 moves, it will drive the conductive rod 5 to move, and when the conductive rod 5 moves, it will contact with the connecting rod 61 to push the connecting rod 61 to move, and at the same time, the static electricity on the connecting rod 61 will be released;

[0040] When the moving rod 610 moves, it will drive the elastic rod 71 to move. When the elastic rod 71 moves, it will drive the impact block 72 to move. When the impact block 72 moves, it will hit the linkage rod 73 and the force block 74. After the linkage rod 73 and the force block 74 are hit, they will drive the shaking wheel 75 to shake, so that the shaking wheel 75 will drive the paper to shake.
