Abstract

A numerical control rewinder relates to a wind-up sealing device, and comprises a frame and two wind-up rolls, a rotating shaft is arranged on one side of the frame, one end of the rotating shaft is connected with a tension air cylinder, and the other end thereof is connected with one of the wind-up roll in a transmission way. Bracket are respectively arranged at both ends of the other wind-up roll on the frame, and a reeling air cylinder is respectively fixed on each bracket; pressure roller brackets are also respectively and movably connected on the brackets, a pressure roller is arranged between the two pressure roller brackets, and is connected with the other wind-up roll in a transmission way, and the reeling air cylinders are connected at the part where the pressure roller brackets are adjacent to the pressure roller. The rewinder adopts the scheme that the rotating shaft is driven to rotate through the tension air cylinder to further enable the wind-up rolls to rotate an angle and tense the tail part between the paper roll in the rewinder and the wind-up rolls, so as to solve the problem of loose rolling or wrinkles of the last several circles of a semi-finished paper roll;and at the same time, the pressure roller is driven to press on a finished paper roll through the reeling air cylinder, and is driven to rotate through the rotation of the two wind-up rolls, so as torealize the firm sticking of the tail part of the finished paper roll under the condition of pressing and to solve the problem of the inaccurate sealing of paper roll by depending on dead weight in the past.

Description

The numerical control rewinding machine

Technical field

The utility model relates to a kind of numerical control rewinding machine, especially relates to a kind of rewinding machine finished roll and has rolled up rolling closing device afterwards.

Background technology

After common full automaticity rewinding machine paper roll is rolled into, by pusher it is pushed between two wind-up rolls, the cutting knife in the middle of two wind-up rolls cuts off paper automatically, then, wind-up roll rotates automatically, and the empennage that cuts off is bonded on the paper roll that is rolled into, and makes it become a complete finished roll.Yet,, cause last several circles of finished roll generally to roll up all very loosely or gauffer arranged because during the empennage seal of paper roll, treating between the volume part in paper roll and the rewinding machine is too loose.The way that solves is that automatic propelling device is destroyed at present, changes into and manually gets volume, the caving-in bash of the real genus of this kind way.

The utility model content

Technical problem to be solved in the utility model provides a kind of paper roll and is rolled into afterwards and can roll up the rewinding machine of part tension with rolling up partial sum.

For solving the problems of the technologies described above, the utility model provides a kind of numerical control rewinding machine, relates to the rolling closing device, comprise support, two wind-up rolls, it is characterized in that: support one side is established a rotating shaft, and rotating shaft one end connects the piston rod of tension cylinder, and the other end and one of them wind-up roll are in transmission connection.

It is more accurate for paper roll is sealed, be positioned at another wind-up roll two ends on the support and establish a support respectively, be fixed with the volume air cylinder on the support, also be connected with pressing roller holder on the support, be provided with pressure roller between two pressing roller holders, pressure roller and another wind-up roll are in transmission connection, and pressing roller holder connects the piston rod of volume air cylinder near the pressure roller place.

The piston rod of the utility model by the tension cylinder drives rotating shaft and rotates, and then makes wind-up roll rotate an angle, and the empennage between the paper roll in the rewinding machine and in the wind-up roll is partly strained, and the last several circles that solve the half-blank paper roll are rolled up loosely or crisp problem; Pass through the piston rod drive pressure roll-in of volume air cylinder simultaneously again on finished roll, and the rotating band dynamic pressure roller that passes through two wind-up rolls rotates, be implemented in the empennage that cements finished roll under the situation about pressing down, it is accurately sealed, solving conducts oneself with dignity by paper roll in the past seals inaccurate problem.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the birds-eye view of Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, the utility model comprises support 4, two wind-up

rolls

10,19, support one side is established a rotating shaft 3, rotating shaft one end connects the piston rod of tension cylinder 2, the other end is in transmission connection by the sprocket wheel 7 on ratchet on it 6 and the wind-up

roll

19,5, the 9th, bearing seat, two wind-up

rolls

10 and 19 are in transmission connection by 8 and 20.

It is more accurate for paper roll is sealed, be positioned at another wind-up roll 10 two ends on the support and establish a L bracket 16 respectively, be fixed with volume air cylinder 13 on the support, also be connected with pressing roller holder 14 on the support, be provided with pressure roller 12 between two pressing roller holders, pressure roller 12 is in transmission connection by the sprocket wheel 18 of its both sides and the sprocket wheel 17 on double-stranded wheel 15 and the wind-up roll 10, and pressing roller holder 14 connects the piston rod of clamping cylinders 13 near the pressure roller places.

When finished product paper roll 11 is pushed between two wind-up rolls, computer sends instruction, make the withdrawal of tension cylinder 2 piston rods, connecting rod 1 drives rotating shaft 3 and rotates, make ratchet 6 turn over an angle simultaneously, empennage between the paper roll in the rewinding machine and in the wind-up roll is partly strained, and cutting knife cuts off again afterwards, guarantees the compact complete of finished roll outermost 1-2 layer volume.Computer sends instruction stretches out the piston rod of volume air cylinder 13, and pressure roller 12 is pressed on the finished roll 11, gives the suitable pressure of paper roll, make seal accurately complete, afterwards, wind-up

roll

10 and 19 and pressure roller 12 clockwise rotate, finished roll is pushed to next manufacturing line.

Claims

1, a kind of numerical control rewinding machine relates to the rolling closing device, comprises support, two wind-up rolls, and it is characterized in that: support one side is established a rotating shaft, and rotating shaft one end connects the piston rod of tension cylinder, and the other end and one of them wind-up roll are in transmission connection.

2, numerical control rewinding machine according to claim 1, it is characterized in that: be positioned at another wind-up roll two ends on the support and establish a support respectively, be fixed with the volume air cylinder on the support, also be connected with pressing roller holder on the support, be provided with pressure roller between two pressing roller holders, pressure roller and another wind-up roll are in transmission connection, and pressing roller holder connects the piston rod of volume air cylinder near the pressure roller place.
