Detailed ways

As shown in Figures 1 to 5, the utility model includes a frame 1, a pay-off shaft 2, a guide roller 3, a first tension roller 41, a second tension roller 42, and a take-up shaft 5. The new model is described in detail.

As shown in Figure 1 and Figure 2, the frame 1 is the base of the present utility model, and the frame includes a lower leg 11 and an upper U-shaped metal piece, and a pair of pay-off shaft supports are arranged on the left side of the top of the frame 21. The installation end of the pay-off shaft support is hingedly connected with the frame, and a first semicircle hole 211 is provided at the working end of the pay-off shaft support, and a second semicircle hole is provided at the top of the frame corresponding to the first semicircle hole 12. When the support of the pay-off shaft is in contact with the top of the frame, the first semicircular hole and the second semi-circular hole enclose a support cavity for accommodating and supporting the pay-off shaft, and the pay-off shaft can rotate in the support cavity. The first semicircular hole is a blind hole, so as to prevent the pay-off shaft from breaking away from the pay-off shaft support. For the convenience of limiting the position of the whole tape reel on the pay-off shaft, two limit blocks 22 are arranged on the pay-off shaft. The limit blocks are ring-shaped metal parts. Sliding, and a jacking screw is set between the limit block and the pay-off shaft to realize the locking of the limit block. During installation, as shown in Figure 3, rotate the pay-off shaft support so that the active end of the pay-off shaft support is separated from the frame, and then place the whole tape reel on the pay-off shaft between the two stoppers. In order to realize the displacement of the pay-off shaft in the radial direction, a locking bolt is provided between the free end of the pay-off shaft support and the frame.

On the frame on the right side of the pay-off shaft, a guide roller 3 is installed through bearing rotation, and several annular grooves 31 are arranged on the guide roller. axis of the shaft. On the frame on the right side of the guide roller, the first tension roller 41 and the second tension roller 42 are rotated through the bearing assembly, the axis of the first tension roller is higher than the guide roller, and the axis height of the second tension roller is between Between the guide roller and the first tension roller.

The top of the frame on the right side of the second tension roller is provided with a take-up shaft fixed support 51 and a take-up shaft movable support 52. In the bobbin fixed support, and the take-up shaft and the take-up shaft fixed support are relatively fixed in the axial direction. The front side of the top of the frame is provided with a guide rail 7, as shown in Figure 5, a take-up shaft movable support 52 is slidably installed on the guide rail, and an extension plate 521 is arranged on the take-up shaft movable support, between the extension plate and the guide rail There are locking bolts in between. The other end of the take-up shaft is rotatably connected with the movable support of the take-up shaft, and the take-up shaft can relatively move axially in the movable support of the take-up shaft. Place the take-up reel on the take-up spool, move the take-up spool movable support on the guide rail, both can realize the separation of the take-up spool and the take-up spool movable support, to facilitate the installation of the take-up reel.

The rear side of the frame is provided with a stepping motor 8, and the output shaft of the stepping motor is fixedly connected with the take-up shaft. A counter is arranged on the frame, and the counter is used to record the number of turns that the take-up shaft turns, which is a prior art and will not be described in detail. The counter is connected with the signal of the controller arranged on the frame, and the controller is connected with the signal of the stepping motor.

As shown in Figure 4, the counter records the number of turns that the take-up spool has turned, and the number of turns that the take-up spool has turned corresponds to the determined length of the tape 61, which is wound into a small tape for the operator to use. When the take-up shaft recorded by the counter has turned a certain number of turns, the counter sends a signal to the controller, and the controller sends a signal to the stepping motor, so that the stepping motor stops rotating. At this point, the adhesive tape of the set length is wound on the take-up reel for the operator to use.

When winding the tape on the whole tape roll into several small discs, first install the whole tape roll 6 on the pay-off shaft, then pull out the tape head, and pass through the lower part of the guide roller and the upper part of the first tension roller in turn. , The lower part of the second tension roller is wound on the take-up reel. The setting of the guide roller is used to guide the tape pulled out to prevent the tape from deflecting. The first and second tension rollers are used to tension the tape.
