Background technique

When carrying out professional cutting, lamination coating and rewinding to various films, release stationery, typically using cut into Row cutting at present in the wrap-up of rewinding machine, is only capable of winding paper by wind-up roll, can not rule out winding Paper between gap, paper automatically loosely, can not store paper after the completion of making winding, and paper is caused to generate gauffer.

Utility model content

A kind of rewinding machine wrap-up for pneumatic control that the utility model provides to solve the above-mentioned problems, including branch Frame includes that two scalable encoders, two cylinders, two winding rocker arms and wind-up roll, the wind-up roll can turn on the bracket Dynamicly fixed the wind-up roll is connect with a motor on the bracket, and roller, two receipts are equipped between two winding rocker arms Volume rocker arm is rotatably arranged on the bracket by the roller, and the cylinder includes cylinder barrel and piston rod, two cylinder barrels One end be rotatably arranged on the bracket, one end of the piston rod is movably disposed in the cylinder barrel, two The other end of piston rod forms fixation with two winding rocker arms respectively, and two cylinders are electrically connected with two scalable encoder formation respectively It connects, pressure roller is equipped between two winding rocker arms, the pressure roller is 0-20mm with the wind-up roll distance L.

It further, further include PLC controller on the bracket, the scalable encoder is formed with the PLC controller Electrical connection, the PLC controller can control the moving distance of the piston rod, to reach the size of command range L.

Further, there are also angular encoder, the angular encoder and the rollers to form electricity on the winding rocker arm Connection, the angular encoder are electrically connected with PLC controller formation, can feed back the current angle of the winding rocker arm extremely The PLC controller.

It further, further include multiple deflector rolls on the bracket, multiple deflector rolls can be rotatably set on the bracket, multiple Paper is transported at the pressure roller by deflector roll, prevents curl.

Further, also there is pneumatic proportional valve, the pneumatic proportional valve is fixed on the cylinder, energy on the cylinder The tilt angle for the winding rocker arm being enough precisely controlled and the size of distance L.

The beneficial effect of the rewinding machine wrap-up of above-mentioned pneumatic control is: pressure roller can flatten paper, be not easy pine It dissipates, winding rocker arm can be adjusted the angle with the increase of the diameter of wind-up roll, keep the distance between wind-up roll and pressure roller constant.

Detailed description of the invention

In figure: 1, bracket, 2, cylinder, 3, winding rocker arm, 4, wind-up roll, 5, deflector roll, 21, piston rod, 22, cylinder barrel, 23, gas Dynamic proportioning valve, 32, angular encoder, 33, pressure roller, 34, roller.

Specific embodiment

The utility model is further elaborated with reference to the accompanying drawing:

As shown in Fig. 1, the rewinding machine wrap-up of a kind of pneumatic control, including bracket 1 include two on bracket 1 and stretch Contracting encoder (not shown), two cylinders, 2, two winding rocker arms 3 and wind-up roll 4, wind-up roll 4 are rotatably mounted to branch On frame 1, wind-up roll 4 is connect with a motor, and roller 34 is equipped between two winding rocker arms 3, and two winding rocker arms 3 pass through roller 34 are rotatably arranged on bracket 1, and cylinder 2 includes cylinder barrel 22 and piston rod 21, and one end of two cylinder barrels 22 is rotationally set It sets on bracket 1, one end of piston rod 21 is movably disposed in cylinder barrel 22, and the other end of two piston rods 21 is respectively with two A winding rocker arm 3, which is formed, to be fixed, and two cylinders 2 are electrically connected with two scalable encoder formation respectively, between two winding rocker arms 3 Equipped with pressure roller 33, pressure roller 33 and 4 distance L of wind-up roll is 0-20mm.

It specifically, further include PLC controller (not shown) on bracket 1, the scalable encoder and the PLC are controlled Device forms electrical connection, and the PLC controller can control the moving distance of piston rod 21, to reach the size of command range L.

Specifically, it winds there are also angular encoder 32 on rocker arm 3, angular encoder 32 is electrically connected with the formation of roller 34, angle Degree encoder 32 and the PLC controller formation is electrically connected, and can be fed back and be wound the current angle of rocker arm 3 and control to the PLC Device.

It specifically, further include multiple deflector rolls 5 on bracket 1, multiple deflector rolls 5 can be rotatably set on bracket 1, multiple deflector rolls 5 Paper is transported at pressure roller 33, curl is prevented.

Specifically, also there is pneumatic proportional valve 23, pneumatic proportional valve 23 is fixed on cylinder 23, can be accurate on cylinder 2 The tilt angle of the winding rocker arm 3 of control and the size of distance L.

When distance L is greater than 0, pressure roller 33 can be evened up paper directly, then straight paper sheet delivery to wind-up roll 4 is wound Get up；When distance L is equal to 0, air when pressure roller 33 can wind wind-up roll 4 between paper in gap is discharged, can be by paper Compacting is opened, can be loosed off after the completion of preventing wind-up roll 4 from winding, additionally it is possible to adjust winding rocker arm 3 to adjust pressure roller 33 and winding Pressure between roller 4.When wind-up roll 4 winds paper, the diameter of wind-up roll 4 the more can be rolled up the more big therewith, the PLC controller, By calculating the speed and diameter of wind-up roll 4, the angle of control winding rocker arm 3 remains unchanged distance L.

Embodiment described above, only the preferred embodiments of the utility model, are not the implementation model to limit the utility model It encloses, therefore all equivalent change or modifications done according to structure, feature and principle described in present utility model application the scope of the patents, it should all It is included in the scope of the utility model patent application.
