Detailed Description

So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.

According to the utility model discloses an aspect provides a label removing device, include: the conveying device 1 at least comprises two conveyors with opposite working surfaces, and a clamping area for clamping the plastic bottle 4 is formed between the two opposite working surfaces; the cutting device 2 is arranged above the clamping area, and comprises a body and a cutting knife connected below the body, and at least part of the cutting knife extends into the clamping area; the recovery device 3 comprises a tubular collection channel and a negative pressure device capable of generating negative pressure inside the collection channel, and the open end of the collection channel is arranged right opposite to the clamping area.

The working process of the label removing device is approximately as follows: the plastic bottles 4 enter the clamping area under the action of external force, are clamped by two conveyors in the same conveying direction and move forwards along with the operation of the conveyors, and the labels on the plastic bottles are cut by the cutter 21 when passing through the cutting device 2. The label is cut off and then dropped from the plastic bottle 4, and is sucked by the recovery device 3. Realizing automatic label removal in the recovery of the plastic bottle 4.

The conveyors arranged oppositely may be in the left-right direction or in the up-down direction, which is not limited herein. For convenience of description, all the embodiments hereinafter are provided as examples only in the left-right direction.

The conveyors can be belt conveyors or chain scraper conveyors and mesh belt conveyors, the driving shafts of which are vertical to the advancing plane of the plastic bottles 4, and the working surfaces of the two conveyors are kept parallel and are separated by a certain distance.

In some embodiments, the distance between the two conveyors can be adjusted, in particular, for example, by providing a work platform on which a second slide 23 is provided, perpendicular to the direction of movement of the bottles 4. The conveyors are fixedly connected to the second slide rail 23 through the frame, so that the conveyors can slide along the slide rail 23, thereby adjusting the distance between the conveyors. Wherein, according to the in-service use operating mode, can only connect the conveyer of one side on second slide rail 23, also can all connect the conveyer of both sides on slide rail 23.

In some embodiments, the distance between the oppositely arranged conveyors is adjusted to be slightly smaller than the size of the plastic bottle 4, the plastic bottle 4 is extruded by the conveyors after entering the clamping area, the friction force between the conveyor and the conveyor is increased, and the conveying device 1 clamps the plastic bottle 4 and moves forwards only by means of the friction force;

optionally, baffles are arranged on the conveyor belt of the conveyor on at least one side at intervals, and the width of each baffle is slightly smaller than the distance between the oppositely arranged conveyors. A cuboid space with two open ends is formed between the baffle and the two opposite conveying belts, and the plastic bottles 4 are accommodated in the cuboid space and move forwards under the driving of the baffle. Wherein, in order to guarantee that the plastic bottle 4 can not drop and guarantee that the label that drops can be retrieved by recovery unit 3 smoothly, set up the grid structure that only allows the label to pass through in the below of conveyer belt.

Because the existing label is mostly of a strip-shaped structure and is adhered at the two ends after surrounding the plastic bottle 4 for a circle to form a tubular structure, the label can be cut more conveniently and time-saving along the axis direction of the plastic bottle 4, and when the label of the plastic bottle 4 is in the advancing direction of the plastic bottle 4 along the axis direction of the label, the advancing movement and the cutting of the plastic bottle 4 are combined, so that the structure is simpler.

In some embodiments, the axis of the plastic bottles 4 is parallel to the conveying direction of the conveyor, the baffles are uniformly arranged and the distance between two adjacent baffles is greater than the length of the plastic bottles 4. All baffles are uniformly arranged, the space can be fully utilized, a space capable of containing the plastic bottle 4 can be formed between any two adjacent baffles, and the label removing efficiency is improved.

In some embodiments, the axis of the plastic bottles 4 is parallel to the conveying direction of said conveyor, the height of the baffles being smaller than the diameter of the plastic bottles 4. The cross section of the labeling position of the plastic bottle 4 is mostly circular or approximately circular, the label is most conveniently cut at the highest point of the cross section, and in order to prevent the cutter 21 from colliding with the baffle due to the influence of the overhigh height of the baffle, the height of the baffle is smaller than the diameter of the plastic bottle 4.

The cutting device 2 comprises a body and a cutting knife connected to the body, wherein the cutting knife can be a fixed linear blade or a rotary circular blade. The position of the cutting-off knife relative to the body can be fixed, and the cutting-off knife is fixedly arranged at a certain position according to the size of the plastic bottle 4, so that most of labels can be cut off after passing through the cutting-off knife.

In some embodiments, the severing knife is movably arranged in a direction perpendicular to the conveying direction of the conveyor. The cutting-off knife can move up and down to adapt to the change of different sizes of the plastic bottle 4, and when the size of the plastic bottle 4 is larger, the cutting-off knife moves upwards; when the size of the plastic bottle 4 is small, it moves downward.

Further, the body comprises a slide rail 23 and a slide block 22 which are arranged in the vertical direction, and the cutting-off knife is arranged below the slide block 22 and can move up and down along the slide rail 23 along with the slide block 22.

Optionally, a pressure sensor is disposed between the cutting blade and the slider 22 to obtain a pressure parameter required for controlling the movement of the cutting blade. When the cutting knife moves downwards to touch the plastic bottle 4, the plastic bottle 4 applies certain pressure to the pressure sensor through the cutting knife, and when the pressure reaches a fixed value, the cutting knife is considered to be in full contact with the plastic bottle 4, so that the cutting action of the label can be completed, and therefore the downward movement is not required to be continued.

According to another aspect of the utility model, a plastic bottle 4 treatment facility is provided, including any one kind of above-mentioned label device that takes off.
