Description

Bottom device for shrink label

The present invention is a bottom wrapping device for shrink labels, in particular to a bottom wrapping device that places a container at a certain height to set the shrink film on the bottom of the container.

According to the prior art, such as the invention patent No. I458660, an input device and an output device of the prior art labeling machine are arranged on both sides of the frame of the bottle raising device, and the container is transported to the clamping mechanism through the input device. The clamping mechanism is provided with a lower bottle holder and an upper bottle holder. The lower bottle holder is provided with side tables on both sides, and the height of the lower bottle holder is higher than the side table. The top surface of the rack is provided with a working plane and a positioning mechanism is provided on the working plane. The positioning mechanism is provided with a toggle member, which is used to move the label film down to the bottom of the container, so that the label film on the outside of the container can be pressed against the top surface of the side table, and then the container is shrunk by the heat drying device and then covered The bottom and body of the container.

In the aforementioned conventional technology, although the bottle holder is set on the clamping mechanism and is higher than the side table, when the container is placed on the lower bottle holder to cover the label film, the label film is moved to the bottom of the container by the toggle member, but the toggle The piece is moved in a single direction and fixed force. When the label film is moved to the bottom of the container, the label film may be damaged or the label film cannot be accurately dialed to the preset position or cannot be accurately dialed to the label film. The problem is that the user will be greatly affected when using its function. If the dial of the bottle raising device is unevenly applied to the label film, the label film may be damaged or the label cannot be accurately dialed to the expected value. Because of the location problem, the bottle raising device of the conventional labeling machine is not very practical.

For this reason, the inventor of the present invention has accumulated many years of experience in the production and research and development of various sleeve labeling machines, and invented this case specifically to solve the problem that the label position of the former and the prior art cannot reach the required positioning.

The purpose of the present invention is to provide a bottom wrapping device for shrink labels. The container is set at a certain height to wrap the shrink film to the bottom of the container to improve the packaging texture of the container and solve the problem that the sleeve labeling machine cannot wrap the shrink film on the container. The bottom problem can be adjusted with containers of various sizes to realize the packaging of diversified products.

In order to achieve the aforementioned purpose, the bottom packaging device of the shrink label of the present invention includes at least a conveying device, a lower pressing plate and a side plate; the conveying device is equipped with a transmission device, a conveyor belt and a conveying screw.

The surface of the aforementioned conveyor belt is provided with a plurality of supporting disc elements, and the aforementioned disc element and the conveying belt are locked or glued by screws or fasteners or bolting elements. The material is pasted and fixed, the aforementioned tray element can be set for the container, the aforementioned tray element is arranged equidistantly, and protrudes high above the surface of the conveyor belt, so that the shrink film can be sleeved under the bottom of the container, and the conveyor screw is recessed Patterns and convex patterns, the central point of the aforementioned plate element and the central position of the aforementioned concave pattern are mutually positioned, and the arc of the aforementioned concave pattern is adjusted according to the diameter of the container; the side of the conveying device is provided with a base, and the base is provided with a lower pressure plate and a side plate In order to allow the shrink film of the container to be smoothly pressed down, a certain range of upturned plates is formed at the entrance end of the lower pressing plate. The rear end of the upturned plate forms a front section and a rear section of different heights. The height of the section is greater than that of the rear section, so that the shrink film can be smoothly pressed down to an appropriate position. When the sleeve labeling machine sets the shrink film on the periphery of the container, the container is transported to the conveyor screw and side plate by the conveyor belt. Within the operating range of the lower platen, the aforementioned side plate and the conveying screw operate correspondingly to produce the effect of the conveying container moving forward and being positioned. The purpose is to prevent the aforementioned lower platen pressing the shrink film from causing the container to shift or deviate. The shrink film is pressed down slightly below the bottom end of the container, and then the shrink film is shrink-wrapped to the bottom end of the container by a heating device.

In the bottoming device of the shrink label of the present invention, the aforementioned side plates can be replaced with one or more conveying screws according to requirements. Of course, if one or more conveying screws are provided, the transmission method of the transmission device must be adjusted according to the requirements, so that the container can be quickly conveyed And positioning.
