Technical Field

The invention relates to the field of paper product processing, in particular to an automatic adjusting mechanism for a gap between rollers.

Background

Since the paper making art of Chuan-Lun invented by 2000 years ago, the variety of paper is covered with all the elephants, and the forest universities, in order to meet different use requirements of people, people can paste different papers together, and an automatic covering machine is a common one.

An automatic covering machine is a paper product processing device for pasting two pieces of paper together. The full-automatic paper conveying, deviation rectifying, gluing and press fitting, press conveying and curing and paper collecting are realized by adopting the automatic surface paper conveying, the automatic bottom paper conveying, the deviation rectifying, the gluing and press fitting, the press conveying and curing and the paper collecting.

In actual use, the manual adjusting mechanism is adopted for adjusting the gap between the rollers, but in actual production, the gap between the two ends of the upper paper conveying roller and the lower paper conveying roller is complex to adjust, the gap between the worm gear shaft and the sliding block locking nut is greatly influenced by the thread machining precision, and the uniform and consistent gap between the two ends of the upper paper conveying roller and the lower paper conveying roller is difficult to ensure.

Disclosure of Invention

An object of an embodiment of the present invention is to provide an automatic adjusting mechanism for a gap between rollers, so as to solve the problems in the background art.

In order to achieve the above purpose, the embodiments of the present invention provide the following technical solutions:

an automatic regulating mechanism for the gap between paper rollers is composed of an electric cylinder module fixed to left and right wall plates via spacer and connector, an upper paper roller fixed to left and right wall plates via slide block and rolling bearing, a lower paper roller fixed to left and right wall plates via bearing seat and rolling bearing, a motor with output end connected to the first synchronous pulley, a second synchronous pulley connected to the first synchronous pulley via synchronous belt, a second synchronous pulley connected to the upper end of the feeding shaft and locked by the second fastener, and a connecting part connected to the lower end of the feeding shaft, the paper feeding mechanism is characterized in that the paper feeding mechanism is converted into up-and-down movement of a feeding shaft, so that up-and-down movement of a sliding block of an upper paper conveying roller is driven, a gap between the upper paper conveying roller and a lower paper conveying roller is changed, paper products can be conveyed smoothly by adjusting the gap, the change of the gap distance between the upper paper conveying roller and the lower paper conveying roller is consistent with the up-and-down movement distance of the feeding shaft and synchronous, the gap is generally slightly smaller than 0.1-0.25mm of the thickness of bottom paper, the gap cannot be adjusted to be too small, the corrugated paper can be flattened by too small, glue solution cannot be coated on the highest position of the corrugated paper, the bonding strength is influenced, and when the bottom paper is a paperboard. The slider of the last roller of defeated paper is installed in left wallboard and right wallboard, the slider of the last roller of defeated paper can slide from top to bottom in left wallboard and right wallboard, the motor rotates, the rotary motion of feed shaft and second fastener is driven by synchronous pulley, the circular motion of hold-in range, convert the up-and-down linear motion of feed shaft into, and then drive the slider of the last roller of defeated paper and reciprocate, the precision that the feed shaft reciprocates is up to 0.01mm, the lower roll of defeated paper is the fixed roll, also be the benchmark roller that the last roller of defeated paper corresponds the distance of defeated paper lower roll (H2), H1 represents and carries paper thickness, when H2< H1, the paper is carried away through the roller. The electric cylinder component is adopted to drive the upper paper conveying roller to move up and down to adjust the gap between the upper paper conveying roller and the lower paper conveying roller, the distance H2 can be accurately controlled, H2= H1 0.95, when the thickness of the paper conveyed by the paper H1 is input, after the adjustment is determined, the upper paper conveying roller is automatically adjusted to the distance H2, a rotatable operation control box is stably kept at one side of a product, a touch display screen is arranged on a panel of the operation control box, a man-machine conversation input box is displayed on the touch display screen, corresponding numbers of H1 are input into the conversation input box, corresponding parameters of H1 can be correspondingly changed, according to the corresponding numbers H1 input into the conversation box, the corresponding numbers are compiled through a computer program, the calculation of a PLC control program module is carried out, instructions are given, the up-and down movement amount of the feeding shaft is controlled by controlling the period of the rotation time of the motor, and the distance H2 is automatically adjusted, and then the gap between the upper paper conveying roller and the lower paper conveying roller is changed, and the paper can be conveyed smoothly by adjusting the gap.
