Description

Technical Field

[0001] This utility model relates to a machine for shrinking packaging bottle labels, specifically a device that uses heat shrinking to attach label films to the bottle body. More specifically, it is a device that uses steam to heat the packaging bottle, causing the label sleeve to shrink and automatically adhere tightly to the bottle body. Background Technology

[0002] Currently, packaging bottles are widely used in various fields such as food, pharmaceuticals, and cosmetics. After being manufactured, packaging bottles are generally stored in warehouses. The shrink labeling process is completed by the manufacturers in each field during the post-packaging stage.

[0003] Existing machines typically have multiple stations, using a conveyor belt to continuously transport bottles into the same steam chamber, causing the labels to shrink and adhere tightly to the bottle body when heated, and then the conveyor belt takes the bottles out of the steam chamber.

[0004] Packaging bottles come in various shapes, including round and non-round. The shrink labeling process for round bottles is relatively simple. Because the label sleeve can automatically adjust during the heat shrinking process, and there is no need for alignment issues with the bottle itself, the labels can present a neat and regular appearance after being applied, which requires less attention to the process and machine structure.

[0005] The label reduction process for non-circular bottles, such as square and oval bottles, is more complex. When reducing the label on these bottles, there is a problem that the label needs to be aligned with the position of the bottle body. Because the front and back sides of the bottle body are entering the steam chamber at different times, the overall heating is uneven, which often results in label misalignment or displacement. The defect rate of the reduced label is relatively high, and the existing machines and processes are difficult to meet the requirements of manufacturers. Utility Model Content

[0006] The purpose of this invention is to provide a bottle shrink label device that is suitable for shrinking labels on round and non-round bottles. In particular, for non-round bottles, it can ensure that the label is aligned with the bottle body, and it is not easy for the label to shift or misalign. The shrink label has a high qualification rate.

[0007] The objective of this utility model is achieved through the following solutions: A bottle shrink labeling device includes one or more workstations set at corresponding positions on a conveyor belt. Each workstation is equipped with an independent and closed steam chamber. The steam chamber is composed of two templates located on the left and right sides. The two templates can move left and right to close or open the steam chamber, so that the mold cavity of the templates forms a closed steam chamber. The templates are equipped with steam solenoid valves to control the entry of steam, which are used to control the introduction of steam into the steam chamber when it is closed.

[0008] In this way, when one or more bottles are conveyed to one or more corresponding workstations by the conveyor belt, the templates on both sides of the steam chamber can be moved and aligned to form an independent and closed space. Then, the steam solenoid valve can be opened to allow steam to enter the steam chamber. In the steam chamber, the bottle's label can be simultaneously and as a whole subjected to the action of steam and shrink.

[0009] The bottle shrink label device created by this invention ensures that the bottle label is heated evenly and shrinks tightly to the bottle body because the bottle label is simultaneously subjected to steam in the steam chamber. This results in accurate label alignment and prevents misalignment or displacement.

[0010] The packaging bottle shrink label device of this utility model uses the closing and opening of two templates to realize the steam chamber. When opening, the steam solenoid valve can be closed first, and the steam chamber can quickly dissipate heat when the templates are separated, so that its temperature drops rapidly. Therefore, it can avoid the label of the next or the next batch of bottles from being affected by the residual heat of the steam chamber and causing wrinkles.

[0011] This bottle shrink labeling device has the advantage of energy saving because the steam solenoid valve is closed and the steam chamber is open during the conveyor belt transport of each bottle. Therefore, it is not necessary to continuously supply steam to the steam chamber throughout the entire operation. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of a specific implementation structure of a packaging bottle shrink label device of utility model; Figure 2 yes Figure 1 Schematic diagram of the closed structure of the vapor chamber of the bottle shrink label device. Detailed Implementation

[0013] The specific embodiments of the utility model will be further described in detail below with reference to the accompanying drawings: Reference Figure 1 and Figure 2 The packaging bottle shrink label device of this specific embodiment includes a motor (1), a conveyor belt (2), and several independent steam chambers (3) located at the corresponding work positions of the conveyor belt, and a cylinder (4) that drives the opening and closing of several steam chambers (3). Each steam chamber (3) consists of two templates (31) set on the left and right sides. Each template (31) is equipped with a track (33) and is installed on the track (33) by a slider (32). The cylinder (4) can drive the template (31) to move left and right along the track (33) through the slider (32), so that the two templates (31) on the left and right sides are aligned or separated. When the two templates (31) on the left and right sides are aligned, the mold cavity (3a) of the template (31) can form a closed space. The template (31) is equipped with a steam solenoid valve (34) for controlling the introduction of steam, which is used to introduce steam into the closed space when the template (31) is aligned and the steam solenoid valve (34) is opened.

[0014] In this way, when the motor (1) rotates, the conveyor belt (2) can bring a set of labeled packaging bottles into several workstations. Then, the corresponding left and right templates (31) can be aligned under the drive of the cylinder (4), creating an independent and closed space for the bottles in each workstation. Then, the steam solenoid valve (34) is opened, allowing the bottles in each steam chamber (3) to be heated by the steam. As a result, the labels on the bottles shrink and stick tightly to the bottle body. Finally, the steam solenoid valve (34) is closed to prevent steam from continuing to enter the steam chamber (3), and the corresponding left and right templates (31) can be separated under the drive of the cylinder (4), allowing the temperature of each steam chamber (3) to drop rapidly. At the same time, the shrunken bottles can be carried out of each workstation by the conveyor belt (2), and the next set of labeled packaging bottles to be processed can be brought into each workstation.
