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.
Disclosure of Invention

Above-mentioned technical scheme's square cup annular knurl mechanism of single gyro wheel, the rolling route of annular knurl during operation knurling wheel is the same with the cam curve of cam groove, both are close to the transmission route each other for a short time, can guarantee the roll precision of knurling wheel, then the cam curve through design cam groove is the same with the square inner chamber shape of knurling cover, so, the contact pressure that the knurling wheel can easily guarantee the knurling wheel to act on square cup bottom of cup promptly at the knurling during operation keeps unanimous completely, ensure the annular knurl quality, and this annular knurl quality does not receive the upper and lower activity of ejector pin and other factors influences such as inclined plane promotion chute, effectively improve annular knurl speed. In addition, the knurling process has the advantages of less corresponding actions, less action parts and very simple structure.
Preferably, the vertical wheel shaft is arranged on a crank, the crank is hinged to a transmission arm, the transmission arm is fixedly connected with a transmission shaft, the transmission shaft is rotatably arranged in the knurling seat, and the lower shaft end of the transmission shaft is in transmission connection with a power driving mechanism. Through the design, when the transmission shaft rotates, the transmission arm and the crank can be driven to rotate, and then the guide roller is driven to roll along the cam groove, and the knurling wheel is driven to roll along the wall of the square inner cavity of the knurling sleeve simultaneously, so that the knurling action of the cup bottom of the square cup is completed.
Preferably, the cam groove is provided with a notch at a knurling start position, the notch is filled by a movable block, the movable block is provided with a guide groove to keep the cam groove continuous, and the movable block is movably arranged in the radial direction. Through above-mentioned design, can make and let the knurling wheel leave the cam groove 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 and moves inwards as the cylinder, can make guide roller leave the cam groove in the square inner chamber wall of annular knurl wheel and annular knurl cover leaves great clearance between, in the square cup bottom before letting the annular knurl can enter into annular knurl mechanism, also let the square cup that the annular knurl was accomplished leave annular knurl mechanism simultaneously.
Preferably, the bottom of the movable block is connected with a roller, the roller moves radially and is pushed by a roller groove, the roller groove is formed in a rotating disc, the rotating disc is rotatably arranged below the cam disc, gear teeth are arranged on the outer circle of the rotating disc partially and are meshed with a rack, the rack is connected with an air cylinder, and the air cylinder is mounted on the knurling base. The rotary disc is simple in design structure, when the air cylinder pushes the rack to act, the rack can push the rotary disc to rotate, and then the roller groove of the rotary disc pushes the roller to enable the movable block to act radially.
