Description
Technical Field
The invention relates to the technical field of paper cup bowl manufacturing, in particular to a knurling mechanism of a paper cup or a paper bowl machine.
Background
In the production process of the paper cup and the paper bowl, knurling operation on the bottom of the paper cup and the paper bowl needs to be carried out, and the knurling operation is completed through a cup bottom knurling mechanism. For the paper cups and paper bowls with square shapes (the square shape does not refer to a specific quadrangle and can be a hexagon or other polygons), knurling on the bottom of the cup is difficult to realize, so the prior art generally adopts an expansion-compression forming mode, but the prior art also adopts a knurling mode rarely, and the patent number 200610151940.9 and the patent name 'a square paper cup bottom knurling device of a paper cup forming machine' are disclosed. The technical scheme that this patent adopted is that the radial action of promoting the slider through the upper and lower action of ejector pin, and the knurling wheel is installed on the slider, and the shortcoming is: the ejector rod needs to move up and down, the up-and-down movement of the ejector rod is pushed by the cam, the cam is far away from the knurling part, the precision of the cam is greatly reduced when the curve precision is transmitted to the knurling wheel, the contact pressure between the knurling wheel and the cup bottom is difficult to keep consistent during knurling work, and the knurling quality is influenced; in addition, the radial action of the sliding block needs to keep a small sliding gap, so that the knurling wheels arranged on the sliding block can keep stable and good contact with the wall of the square inner cavity of the knurling sleeve to ensure the knurling quality when knurling works, but the small sliding gap not only increases the processing and assembling difficulty, but also has short service life; in addition, because the ejector pin promotes the chute through the top inclined plane and makes the slider action, inclined plane pushing speed can not be very fast, the up-and-down motion of ejector pin also can not be very fast, otherwise can produce very big noise, still return after going on the ejector pin, consequently the rolling speed of knurling wheel along cup bottom knurling position can not be very fast yet during annular knurl work, and production speed is slow.

Through the design, when the transmission shaft rotates, the transmission disc and the crank can be driven to rotate, and then the guide idler wheels are driven to roll along the cam grooves, and all the knurling wheels are driven to roll along the walls of the square inner cavity of the knurling sleeve simultaneously, so that the knurling action of the cup bottom of the square paper cup is completed.
Preferably, the cam groove is provided with a plurality of notches at the knurling initial position to correspond to the plurality of guide rollers, each notch is filled by one movable block, the movable block is provided with a guide groove to enable the cam groove to be kept continuous, and the plurality of movable blocks perform synchronous radial movement. Through above-mentioned design, can make and let all knurling wheels leave the cam groove simultaneously before the knurling work, concrete action is: at the annular knurl initial position, guide roller can be just in time located the guide slot of movable block, promotes the movable block when the cylinder and moves inwards, can make guide roller leave the cam groove, so all knurling wheels can leave great clearance with the square inner chamber wall of annular knurl cover between, in square paper cup bottom before letting the annular knurl can enter into annular knurl mechanism, also let the square paper cup of annular knurl completion leave annular knurl mechanism simultaneously.
Preferably, the notch is located at a transition radius of the cam slot.
Preferably, a cam shaft is arranged on the inner side of the movable block, a compression spring is arranged on the outer side of the movable block, the compression spring pushes the movable block to abut against a cam surface of the cam shaft, the cam shaft is rotatably arranged, a pinion is fixedly connected to the lower shaft end of the cam shaft, a toothed disc is rotatably arranged below the cam disc, an inner gear ring is arranged on the toothed disc and is meshed with the pinion, an outer gear ring is further arranged on the toothed disc and is meshed with a rack, the rack is pushed by an air cylinder to axially move, and the air cylinder is. Above-mentioned design simple structure, when the cylinder promotes the rack action, the rack can promote the fluted disc and rotate, and the rotation of fluted disc then drives all camshafts and rotates, and then makes all movable blocks do synchronous radial motion.
