Detailed Description

The present utility model will now be described in detail with reference to the accompanying drawings. The figure is a simplified schematic diagram illustrating the basic structure of the utility model only by way of illustration, and therefore it shows only the constitution related to the utility model.

As shown in fig. 1-3, the utility model provides an unreeling auxiliary device, which is suitable for a bag making machine 1, wherein the bag making machine 1 comprises a frame 11, one end of the frame 11 is rotatably provided with two driving wheels 12, one end of each driving wheel 12 is fixedly provided with a driving gear 13, and the two driving gears 13 are meshed with each other.

It will be appreciated that one end of one driving wheel 12 is connected to a driving device 2, and that the driving device 2 is configured to rotate the driving wheel 12.

Two support plates 14 are mounted on the end of the frame 11 away from the drive wheel 12, and a groove 15 is formed above the end of the support plate 14 away from the frame 11.

An unreeling wheel 3 is arranged between one end of the supporting plate 14, which is far away from the frame 11, two ends of the unreeling wheel 3 are rotatably provided with clamping blocks 31, the clamping blocks 31 are respectively clamped into the grooves 15 on one side, and the axis of the unreeling wheel 3 is parallel to the axis of the driving wheel 12. The side clamping block 31 is provided with a limit groove 32 corresponding to the supporting plate 14.

It will be appreciated that the unwind wheel 3 is wound with a plastic band (not shown) which, after one end has been extracted, extends between the two drive wheels 12.

In the processing process, one driving wheel 12 is driven by the driving device 2 to rotate, and the driving wheels 12 are synchronously rotated through the engagement between the driving gears 13, so that the two driving wheels 12 clamp the plastic belt and simultaneously draw the plastic belt through the rotation of the driving wheels.

And the groove 15 is used, so that the unreeling wheel 3 is convenient for a worker to install and detach.

The frame 11 is close to the one end of backup pad 14 and still rotates and be provided with auxiliary rod 4, and auxiliary rod 4 is located the top of backup pad 14, and the one end that auxiliary rod 4 kept away from frame 11 rotates and is provided with auxiliary shaft 41, and the axis of auxiliary shaft 41 is parallel with the axis of drive wheel 12. Auxiliary wheels 42 are fixed at two ends of the auxiliary shaft 41, the auxiliary shaft 41 is connected with a driver 43, and the driver 43 is fixedly connected with the auxiliary rod 4. In the present embodiment, the driver 43 is a motor for driving the auxiliary shaft 41 to rotate the auxiliary wheel 42. A telescopic rod 44 is mounted between the auxiliary rod 4 and the frame 11.

It will be appreciated that the drive means 2, the telescopic rod 44 and the drive 43 are controlled by external control devices.

When the plastic belt is fed, the telescopic rod 44 is kept in an extension state, the auxiliary rod 4 is lifted by the support of the frame 11, so that the groove 15 is exposed, the unreeling wheel 3 is conveniently taken out by a worker, and the unreeling wheel 3 is put on the support plate 14 after the plastic belt is sleeved.

When the unreeling wheel 3 is put into, the clamping blocks 31 on two sides of the unreeling wheel 3 are distributed and clamped into the grooves 15 on one side.
