Abstract

The utility model discloses an automatic cutting device of an adhesive-tape non-stopping winding machine, which is arranged on a roll-changing press roller in the adhesive-tape non-stopping winding machine; the end part of the roll-changing press roller is provided with a cutter rod; one end of the cutter rod is provided with a cutter which is parallel with the roll-changing press roller; the other end of the cutter rod is connected to a cylinder; when a finished adhesive tape on the previous winding roller is about to be wound fully, a rotary roller-changing device rotates automatically to lead the next winding roller to get close to the adhesive tape; the roll-changing press roller presses the adhesive tape on the next winding roller tightly; the next winding roller starts to turn and winds the adhesive tape; when the roll-changing press roller presses the adhesive tape on the next winding roller tightly, the cylinder acts to drive a cutter by the cutter rod to automatically cut off the adhesive tape connected between the previous winding roller and the second winding roller, thus the automatic and continuous winding is realized, and the adhesive tape on the previous winding roller can be taken off conveniently. The device of the utility model has high production efficiency; the cut of each roll of the finished adhesive tape is smooth and the length is accordant; so the adhesive tape is not wasted.

Description

Automatic cutting means is not shut down in the adhesive tape rolling

Technical field

The utility model relates to adhesive tape production facilities technical field, relates in particular to the adhesive tape rolling and does not shut down automatic cutting means.

Background technology

In the adhesive tape production process, generally comprise that base material unreels, gluing, oven dry and the rolling of finished product adhesive tape.As shown in Figure 1; existing adhesive tape is not shut down and is provided with rotation changing rig 11 in the wrap-up 1; rotation changing rig 11 comprises two above wind-up rolls 111; be provided with change of lap pressure roller 12 before the described rotation changing rig 11; because the length of every volume adhesive tape base material is general all greater than the length that whenever is rolled into the product adhesive tape; therefore existing adhesive tape is not shut down finished product adhesive tape on the previous wind-up roll 111 in the wrap-up 1 and is about to rolling when full; rotation changing rig 11 rotation automatically makes a back wind-up roll 111 press close to adhesive tape; change of lap pressure roller 12 is pressed on adhesive tape on the back wind-up roll 111; the wind-up roll in back 111 beginning turn rolling adhesive tapes; at this moment also need the adhesive tape that links to each other between previous wind-up roll 111 and the back wind-up roll 111 is cut off, could realize automatic continuous rolling; and conveniently take off adhesive tape on the previous wind-up roll 111.The cut-out mode of existing adhesive tape generally is by artificial gripping cutting knife or draws disconnected or break apart by chopping adhesive tape that this mode is influenced by manual operation, cuts off inaccurately, whenever is rolled into the unfairness of product adhesive tape otch, length is inconsistent.

Summary of the invention

The purpose of this utility model can cut the adhesive tape rolling of adhesive tape automatically and not shut down automatic cutting means when being to provide a kind of rolling.

The technical solution adopted in the utility model is: automatic cutting means is not shut down in the adhesive tape rolling, it is located at adhesive tape and is not shut down in the wrap-up, described adhesive tape is not shut down and is provided with the rotation changing rig in the wrap-up, the rotation changing rig comprises two above wind-up rolls, be provided with the change of lap pressure roller of swing before the described rotation changing rig, the end of wherein said change of lap pressure roller is provided with cutter bar, and an end of cutter bar is provided with the cutting knife parallel with the change of lap pressure roller, and the other end of cutter bar connects cylinder; When the finished product adhesive tape on the previous wind-up roll is about to rolling when full, rotation changing rig rotation automatically makes a back wind-up roll press close to adhesive tape, the change of lap pressure roller is pressed on adhesive tape on the back wind-up roll, the wind-up roll in back begins to rotate the rolling adhesive tape, when the change of lap pressure roller was pressed on adhesive tape a back wind-up roll, cylinder action drove cutting knife by cutter bar and cuts off the adhesive tape that links to each other between previous wind-up roll and the back wind-up roll automatically.

The beneficial effects of the utility model are: adopt said structure; do not shut down at adhesive tape and increase the cutting knife that cuts off automatically on the change of lap pressure roller of wrap-up; when rotation changing rig roll change rolling, cut off the adhesive tape that links to each other between previous wind-up roll and the back wind-up roll automatically, realize rolling continuously automatically, also conveniently take off adhesive tape on the previous wind-up roll.The utility model cuts off accurately, and the production efficiency height is rolled into whenever that product adhesive tape otch is smooth, length is consistent, can not waste adhesive tape.

Description of drawings

Now in conjunction with the accompanying drawings the utility model is further elaborated:

Fig. 1 is the structural representation that existing adhesive tape is not shut down wrap-up;

Fig. 2 is the structural representation that automatic cutting means is not shut down in the rolling of the utility model adhesive tape.

The specific embodiment

As shown in Figure 2, the utility model is located at adhesive tape and is not shut down in the wrap-up 1, described adhesive tape is not shut down and is provided with rotation changing rig 11 in the wrap-up 1, rotation changing rig 11 comprises two above wind-up rolls 111, be provided with the change of lap pressure roller 12 of swing before the described rotation changing rig 11, the end of wherein said change of lap pressure roller 12 is provided with cutter bar 2, and an end of cutter bar 2 is provided with the cutting knife 3 parallel with change of lap pressure roller 12, and the other end of cutter bar 2 connects cylinder 4; When 5 rollings soon of the finished product adhesive tape on the previous wind-up roll 111 are full, rotation changing rig 11 rotation automatically makes a back wind-up roll 111 press close to adhesive tape 5, change of lap pressure roller 12 is pressed on adhesive tape 5 on the back wind-up roll 111, the wind-up roll 111 in back begins to rotate rolling adhesive tape 5, when change of lap pressure roller 12 was pressed on adhesive tape 5 a back wind-up roll 111, cylinder 4 action drove cutting knifes 3 by cutter bar 2 and cuts off the adhesive tape 5 that links to each other between previous wind-up roll 111 and the back wind-up roll 111 automatically.

Claims

1. automatic cutting means is not shut down in the adhesive tape rolling, it is located at adhesive tape and is not shut down in the wrap-up, described adhesive tape is not shut down and is provided with the rotation changing rig in the wrap-up, the rotation changing rig comprises two above wind-up rolls, be provided with the change of lap pressure roller of swing before the described rotation changing rig, it is characterized in that: the end of described change of lap pressure roller is provided with cutter bar, and an end of cutter bar is provided with the cutting knife parallel with the change of lap pressure roller, and the other end of cutter bar connects cylinder; When the finished product adhesive tape on the previous wind-up roll is about to rolling when full, rotation changing rig rotation automatically makes a back wind-up roll press close to adhesive tape, the change of lap pressure roller is pressed on adhesive tape on the back wind-up roll, the wind-up roll in back begins to rotate the rolling adhesive tape, when the change of lap pressure roller was pressed on adhesive tape a back wind-up roll, cylinder action drove cutting knife by cutter bar and cuts off the adhesive tape that links to each other between previous wind-up roll and the back wind-up roll automatically.
