Description

Automatic school circular knitting machine
Technical field
The utility model relates to a kind of school round belting, especially a kind of edition automatic school of roller round belting.
Background technology
General roll bending technology mainly comprises just volume, school circle, submerged-arc welding and reinforcement four procedures, and this four procedure generally all will be by manually finishing at present, so workman's workload is very big.Basically all there is the veneer reeling machine more than three in each plate-making company, because workman's the amount of labour is very big, cause the veneer reeling machine of company not make full use of, simultaneously because volume version and school sired results preface all are to be finished by manually-operated, therefore the control of circularity need be finished according to workman's working experience, cause the circularity size of version wayward, volume version precision is low.
The utility model content
The purpose of this utility model is to overcome the existing school sired results skill defective that precision is low, labor strength is big, has proposed a kind of automatic school circular knitting machine.
The utility model is to adopt following technical scheme to realize: a kind of automatic school circular knitting machine, comprise frame, top roll, two lower rolls and power control box, top roll is connected with hydraulic cylinder, and can move along the vertical direction of frame, lower roll is all fixedlyed connected with frame by bearing block, two lower rolls are parallel to each other, top roll is positioned at the centre position of two lower rolls, lower roll is connected with drive motors, wherein, in the described power control box Programmable Logic Controller is set, its vertical direction of described support upper edge is provided with three step switch successively, and wherein step switch and the distance between the step switch in the bottom at the top is 40-60mm, and step switch 4mm-7mm place is provided with safety switch apart from the bottom, wherein step switch all is connected with Programmable Logic Controller with safety switch, and step switch and safety switch are positioned at the edge of top roll horizontal direction maximum gauge.
In the utility model, the fixed-site of described top step switch and bottom step switch, the position of the step switch in the middle of being positioned at is determined according to version roller size.
Use this circular knitting machine school, school bowlder, press down by the Driven by Hydraulic Cylinder top roll, when top roll when top step switch on the frame contacts, this step switch is opened, by the program in the connected Programmable Logic Controller, the control hydraulic cylinder drives lower roll and presses down fast; Top roll presses down in the process, when with frame on second step switch be that the middle action switch is when contacting, the middle action switch opens, the Controlled by Programmable Controller hydraulic cylinder, top roll is pressed down at a slow speed, and drive motors work simultaneously drives the lower roll rotation, and drive the top roll rotation, promptly begun school sired results preface in the upper and lower roll rotary course; When top roll continues to press down when contacting with the bottom step switch, the bottom step switch is opened, Programmable Logic Controller sends instruction to hydraulic cylinder, hydraulic cylinder drives top roll and gos up at a slow speed, go up to before the middle action switch contacts at top roll, lower roll and top roll are in the rotary course always, and this process is still carried out the school circle to the volume version.When top roll rises to after the middle action switch contacts, the middle action switch opens, lower roll and top roll stop operating afterwards, the top roll fast rise; Until with after the top step switch contacts, top roll recovers to rise at a slow speed.Safety switch then is to be used to prevent can stop top roll to continue to press down when the bottom step switch produces damage, and entire equipment is played a protective role.
The beneficial effects of the utility model are: the utility model make veneer reeling machine can realize automatic school circle function, so entire equipment is simple in structure by add Programmable Logic Controller and step switch and safety switch in veneer reeling machine; This equipment has been realized the automatic school circle of roll bending simultaneously, has improved school circle precision and version roller quality; In addition, greatly reduce working strength of workers, improved operating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A among Fig. 1 is to partial enlarged drawing;
Fig. 3 is the position assumption diagram of top roll and step switch, safety switch.
The specific embodiment
As shown in the figure, this automatic school circular knitting machine comprises frame 1, top roll 2, two lower rolls 3 and power control box 4.Top roll 2 is connected with hydraulic cylinder, and hydraulic cylinder is arranged in the frame.Under the driving of hydraulic cylinder, top roll 2 can move up and down along the vertical direction of frame, and top roll 2 is positioned at the centre position of two lower rolls 3.Lower roll 3 is connected with frame by bearing block, and lower roll 3 is connected with drive motors, and drive motors can drive the lower roll rotation.Be provided with Programmable Logic Controller in the power control box 4.Frame is provided with 5,6,7, three step switch of three step switch and vertically is provided with at interval on the medial surface of top roll, the fixed-site of top step switch 5 and bottom step switch 6 wherein, and its spacing is 50mm.Be provided with middle action switch 6 between top step switch and the bottom step switch, the position of middle action switch 6 is determined according to the size of version roller.Be positioned at 4-7mm place, action 7 switches below, bottom and be provided with safety switch 8.Three step switch and safety switch all are connected with Programmable Logic Controller in the distribution box 4.As shown in Figure 3, step switch and safety switch are positioned at the maximum gauge edge of top roll horizontal direction.
Utilize this circular knitting machine school, school bowlder, at first Driven by Hydraulic Cylinder top roll 2 presses down, and when top roll 2 touched top step switch 5 on the frame side, this step switch was opened, by the control program in the connected Programmable Logic Controller, make hydraulic cylinder drive top roll 2 and press down fast; When top roll 2 press to frame on second step switch be that middle action switch 6 is when contacting, middle action switch 6 is opened, programme-control hydraulic cylinder in the Programmable Logic Controller, top roll 1 decrease speed is diminished, promptly begin to press down at a slow speed, drive motors work simultaneously makes lower roll 3 rotations, and drive top roll 2 rotations, promptly begun school sired results preface in the upper and lower roll rotary course; When top roll 2 continues to press down when contacting with bottom step switch 7, bottom step switch 7 is opened, the programme-control hydraulic cylinder of Programmable Logic Controller, making hydraulic cylinder drive top roll 2 gos up at a slow speed, go up to before middle action switch 6 contacts at top roll 2, lower roll 3 and top roll 2 still are in rotation status, and this process still is in the school sired results preface of volume version.When top roll 2 rose as for 6 contacts of middle action switch, middle action switch 6 was opened, and lower roll 3 and top roll 2 stop operating, top roll 2 fast rise; When top roll 2 rises to after top step switch 5 contacts, top roll 2 recovers to rise at a slow speed.When the bottom step switch damages 7, though bottom step switch 7 can not work, when top roll 2 pressed to safety switch 8 places, safety switch 8 was opened, still can stop top roll 2 to continue to descend, thereby prevent from entire equipment to be produced damage because of top roll 2 excessively presses down.
