Description

Technical Field

[0001] The utility model relates to the fields of automobiles, aviation, clothing, etc., and is mainly used in automatic tape sticking machines, in particular to an automatic tape cutting device. Background Art

[0002] Taking general grid tape as an example, the blade is easily stuck with residual glue, which makes it impossible to cut the tape. Therefore, the blade needs to be cleaned frequently. Therefore, adding a blade oil immersion lubrication device can effectively solve the problem of residual glue on the cutter. This not only ensures the sharpness of the cutter, but also solves the problem of frequent cleaning of the cutter. The traditional tape cutting device consists of a fixed knife, a lifting gate knife, and a feeding device. The tape is fed out of the gap between the fixed knife and the lifting gate knife by the feeding device, and then the tape is fixed on the target object to be pasted. The feeding device is retracted. When the tape bonding length reaches the set value, the lifting gate knife falls to cut the tape, and the lifting gate knife rises again to wait for the next tape application process. However, this structure will have the following shortcomings:

[0003] 1. The overall structural size is too large. After the lifting gate is opened, the feeding device needs to pass through the fixed knife to feed the material. In order to ensure stability during the process of cutting the tape, the fixed knife needs to have a certain thickness to ensure the structural strength when cooperating with the lifting gate to cut. Therefore, it is necessary to ensure that the tape can be cut. In this way, it is inevitable that the cutting device needs to expand a certain thickness and width outside the effective cutting stroke. This patent uses a rodless cylinder to drive the blade to move left and right to cut the tape, which can ensure effective cutting of the tape while eliminating the fixed knife device. This can reduce the size of the cutting device and make the whole machine more compact.

[0004] 2. The blade is prone to residual glue. Since the double blades cooperate to cut the tape, the area in contact with the glue is increased during the cutting process. Since the mesh double-sided tape has a higher viscosity and a thinner thickness, and the blade needs to remain sharp, it cannot be treated with anti-sticking. Although the tape can be cut during cutting, some of the glue will stick to the blade, so that the more the blade works, the more residual glue will be left on it, affecting the cutting efficiency. This patent has no fixed knife device to reduce the contact area with the tape. After the cutter returns to its position, an oil-absorbing felt is added to the cutter magazine position, so that the cutter always remains oily and is not easy to stick to glue, and it will not affect the viscosity of the tape. Summary of the invention

[0005] The utility model aims to overcome the deficiencies of the prior art and provides an automatic tape cutting device, which mainly solves the problems of the overall size of the structure being too large and the blade being prone to residual adhesive.
