Description

Technical Field

[0001] The utility model relates to the field of paper roll processing equipment design, in particular to an air expansion shaft paper pushing structure. Background Art

[0002] Toilet paper rolls are widely used in daily life. Toilet paper rolls usually consist of a tube block and a paper towel wound on the paper tube. Users can directly take the paper towel from the paper tube for use.

[0029] The paper pushing structure of the inflatable shaft also includes a belt transmission device 7, and each adjacent baffle adjustment mechanism 6 is connected by the belt transmission device 7. Specifically, the belt transmission device 7 includes a transmission wheel and a transmission belt. The first lead screw 61 of each baffle adjustment mechanism 6 is sleeved with a transmission wheel, and the transmission belt can bypass the transmission wheel on the adjacent baffle adjustment mechanism 6.

A hole 21 is provided in the middle of the stop block 2, and one end of the air shaft 1 passes through the hole 21, that is, the stop block 2 is arranged on the periphery of the air shaft 1, and the transfer mechanism 3 can drive the air shaft 1 and the stop block 2 to move in the paper feeding path 42.

[0031] The paper pushing structure of the inflatable shaft further comprises a height limiting mechanism 8 and a height adjusting mechanism 9. There are preferably two height adjusting mechanisms 9.

[0032] In a height adjustment mechanism 9, the height adjustment mechanism 9 includes a second lead screw 91, a second nut 92, a support 93, a slider 94 and a slide rail 95. The support 93 is fixedly mounted on the machine base 4 by bolts, the second lead screw 91 is rotatably mounted on the support 93 by a bearing, and the second lead screw 91 is arranged perpendicular to the horizontal plane, the second nut 92 is sleeved on the second lead screw 91 by threaded matching, and the slide rail 94 is fixedly connected to the support 93 by bolts, and the slider 94 is slidably sleeved on the slide rail 94.

The cylinder 82 is preferably two, and the piston rods of the two cylinders 82 are respectively fixedly connected to the height limiting block 81, and the cylinder bodies of the two cylinders 82 are respectively fixedly connected to the second nuts 92 of the two height adjustment mechanisms 9 by bolts. The height limiting block 81 is located above the paper feeding path 42.

[0034] When the pneumatic shaft paper pushing structure of the utility model is in use, the user can first adjust the position of the baffle 5 through the baffle adjustment mechanism 6 according to the roll of paper to be processed, so as to adjust the width of the paper feeding path 42, and also need to adjust the position of the height limiting mechanism 8 through the height adjustment mechanism 9, so as to adjust the height of the paper feeding path 42, so that the paper feeding path 42 can adapt to the roll of paper to be processed.

[0035] The specific operation of the baffle adjustment mechanism 6 is to start the motor connected to the first screw 61, and the corresponding first screw 61 rotates, so that through each belt transmission device, the first screws 61 of all the baffle adjustment mechanisms 6 can also rotate accordingly. Then, due to being restricted by each through hole 41, the first nut 62 on each first screw 61 can move linearly accordingly, and the corresponding connecting blocks 64 can move linearly, so that the two baffles 5 move away from or closer to each other, that is, the width of the paper feeding path 42 is correspondingly increased or the width of the paper feeding path is reduced.

[0036] The specific operation of the height adjustment mechanism 9 is to start the motor connected to the second lead screw 91, then the two second lead screws 91 will rotate in phase, and are restricted by the slide rail 95, then the second nut 92 will move in a straight line along the second lead screw 91, and at the same time, the slider 94 connected to the second nut 92 will slide on the slide rail 95 to avoid its movement from being offset, then the height limiting mechanism 8 connected to the second nut 92 will move up and down accordingly to achieve its height adjustment, and usually after adjustment, the height limiting block 81 of the height limiting mechanism 8 should be slightly higher than the required height of the paper roll.

[0037] After the size of the paper feeding path 42 is adjusted, the external paper roll can be fed into the paper feeding path 42. At this time, the air cylinder 82 in the height limiting mechanism 8 can work, so that the height limiting block 81 moves down and abuts against the paper roll. Then the belt conveying device 33 of the transfer mechanism 3 works, driving the connecting arm 32 to move, and the air shaft 1 and the abutment block 2 connected to the connecting arm 32 through the connecting frame 31 also move accordingly. The abutment block 2 can abut against one side of the paper roll in the paper feeding path 42, and the air shaft 1 can extend into the paper tube of the paper roll accordingly. Then the air shaft 1 works to abut against the paper tube, so that the paper roll can be fully fixed on the air shaft 1. At this time, the paper roll can be effectively fixed and can be suitable for cutting and other processing to reduce its shaking during cutting.

[0038] When the roll of paper needs to be transported, the air cylinder 82 works so that the height limit block 81 moves up and no longer presses against the roll of paper, and the belt conveying device 33 of the transfer mechanism 3 works, and the air shaft 1 and the press block 2 move accordingly, and the roll of paper on the air shaft 1 can also be transported along the paper feeding path 42, so that the roll of paper can be transported to the subsequent processing equipment.

[0039] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
