Problems solved by technology

[0008] In order to solve the above problems, the present invention designs a label-off knife for a polyester bottle label-off machine, and applies the label-off knife to a polyester bottle label-off machine, which not only abandons the traditional chain form, but also solves the problem of large chain wear and tear. The problem of high noise, and it is suitable for high-speed rotation, improves the effect of label removal, and at the same time increases the mechanical stability of the entire equipment

specific Embodiment 1

[0026] The polyester bottle labeling machine of the present embodiment uses the labeling cutter, and its structure is as follows figure 1 shown. The stripping knife includes a rotating shaft (1), an outwardly protruding extension part (2) consistent with the radial direction of the rotating shaft (1), and a blade body connected to the extension part (2). The blade body is divided into The rigid part (3) and the elastic part (4), the rigid part (3) is connected with the protruding part (2), the elastic part (4) is curved in the rotation plane of the shaft, and the elastic part (4) is distributed with blades (5).

[0027] The rigid part (3) and the protruding part (2) are connected by bolts. In this connection, when the blade (5) is not sharp, it is only necessary to replace the blade body instead of the entire stripping knife , reducing the cost of using the off-label knife.

[0028] The bending angle of the elastic part 4 is 60°.

specific Embodiment 2

[0029] The labeling knife for the polyester bottle labeling machine of this embodiment includes a rotating shaft (1), an outwardly protruding protruding part (2) consistent with the radial direction of the rotating shaft (1), connected with the protruding part (2) The blade body, the blade body is divided into a rigid part (3) and an elastic part (4), the rigid part (3) is connected with the protruding part (2), and the elastic part (4) is curved in the rotation plane of the shaft , blades (5) are distributed on the elastic part (4).

[0030] The rigid part (3) and the protruding part (2) are adhesively connected. This connection method is beneficial to reduce the weight of the label removal knife and reduce the burden on the transmission mechanism of the polyester bottle label removal machine.

[0031] The bending angle of the elastic part 4 is 60°.

[0032] In specific embodiment 1 and specific embodiment 2, the blade portion (5) is composed of triangular steel sheets arran...

specific Embodiment 3

[0034] The difference between the label-removing knife for polyester bottle label-removing machine in this embodiment and the specific embodiment 1 or 2 is that the bending angle of the elastic part (4) is 90°. This choice can make the elastic part (4) contact with the polyester bottle in parallel, so that the blade part (5) can reach the best working condition together, and increase the label-off effect of the polyester bottle.

Abstract

The invention provides a label removing knife for a polyester bottle label removing machine, belongs to the technical field of polyester bottle label removing, and particularly relates to a knife structure for removing polyester bottle labels. The label removing knife comprises a rotating shaft, an extension part and a blade body. The direction of the extension part is consistent with the radius direction of the rotating shaft and the extension part extends outwards, and the blade body is connected with the extension part and composed of a rigid part and an elastic part. The rigid part is connected with the extension part, the elastic part is of a curved shape in the rotating plane of the rotating shaft, and a knife edge part is distributed on the elastic part. The label removing knife is applied to the polyester bottle label removing machine, a traditional chain mode is completely eradicated, the problems that a chain is large in abrasion and high in noise are solved, the label removing knife is suitable for high speed rotation, the label removing effect is improved, and mechanical stability of whole equipment is improved.

Description

technical field [0001] A label-removing knife for a polyester bottle label-removing machine belongs to the technical field of label-removing polyester bottles, and in particular relates to a knife structure for removing labels from polyester bottles. Background technique [0002] The polyester bottle labeling machine is used to automatically strip the trademark on the polyester bottle instead of manual labeling. It has the advantages of liberating labor, high efficiency, low cost, and not subject to climate restrictions. [0003] The traditional PET bottle delabeling machine, such as the mechanized delabeling equipment produced by Dajiang Machinery Factory, installs various metal blades such as blades on the inner wall of the drum, and an auger is installed in the cylinder to make the bottle roll in the cylinder. However, this method will cause greater damage to the polyester bottle itself. [0004] There are also polyester bottle labeling machines that cannot remove polyes...
