Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a steering guide rail type label conveying resistance reduction device for labeling machines. Background Technology

[0002] Labeling machines are crucial equipment in the packaging process for affixing labels to product surfaces. However, existing labeling machines, especially at 90-degree turns, cannot use rollers for label transport at these angles and must rely on 45-degree angled guide rails. This method lacks rollers to reduce drag, increasing transport resistance and often leading to label breakage, thus reducing production efficiency and increasing label waste. Current solutions, such as optimizing roller materials or adjusting roller positions, have limited effectiveness and do not fundamentally solve the problem. Utility Model Content

[0033] Furthermore, in one embodiment of this utility model, the steering guide rail 1 is fixed by the steering guide rail fixing structure 4.

[0034] Furthermore, in one embodiment of this utility model, a photoelectric sensor 6 is provided near the starting point of the label paper feed 9, and the photoelectric sensor 6 is connected to the secondary electromagnetic pressure control valve 5.

[0035] Furthermore, in one embodiment of this utility model, the label paper feed 9 in the labeling machine is driven by the label transmission device 12, and a plurality of label positioning devices 10 are provided on the label transmission device 12.

[0036] Furthermore, in one embodiment of this utility model, the label positioning device 10 is fixed on the fixed bracket 11.

[0037] Example 1 This utility model provides a label conveying resistance reduction device for a labeling machine using a steering guide rail, including a steering guide rail 1; the steering guide rail 1 is set at the turning point of the label paper feed 9 in the original labeling machine, so that the label paper feed 9 can bypass it; the surface friction coefficient of the steering guide rail 1 is lower than a preset threshold; the steering guide rail 1 is provided with an air storage groove 3, and the air storage groove 3 is connected to a compressed air source 8.

[0038] Furthermore, the steering guide rail 1 forms a 45-degree angle with the label paper feeders 9 on both sides.

[0039] Furthermore, the surface of the steering guide rail 1 is made of a material with a friction coefficient lower than a preset threshold, which reduces the resistance during tag transmission.

[0040] Furthermore, a coating with a friction coefficient lower than a preset threshold is applied to the surface of the steering guide rail 1, which further reduces the resistance between the label and the steering guide rail 1.

[0041] Furthermore, the compressed air source 8 is connected to the air storage tank 3 through a pipe, and a first-stage pressure control valve 7 is installed on the pipe. After the air storage tank 3 is filled with air, the steering guide rail 1 generates an air cushion effect, which greatly reduces the friction between the label and the guide rail and significantly reduces the resistance.

[0042] Furthermore, the steering guide rail 1 is also provided with an air outlet 2, which is connected to the air storage tank 3. While being inflated, the air is vented through the air outlet 2 to ensure that the pressure does not exceed the threshold.

[0043] Furthermore, in one embodiment of this utility model, the steering guide rail 1 is fixed by the steering guide rail fixing structure 4.

[0044] Furthermore, in one embodiment of this utility model, a secondary electromagnetic pressure control valve 5 is provided at the inlet of the air storage tank 3, and a photoelectric sensor 6 is provided near the starting point of the label paper feeding 9.

[0046] Furthermore, in one embodiment of this utility model, the label positioning device 10 is fixed on the fixed bracket 11.

[0047] Work process description: The steering guide rail 1 is fixedly installed at the turning point of the label feeding via the steering guide rail fixing structure 4. For example, it can be installed on a nearby wall or fixed on a workbench. The label feed bypasses the steering guide rail 1. The secondary electromagnetic pressure control valve 5 is closed, and the compressed air source 8 and the primary pressure control valve 7 are turned on. The photoelectric sensor 6 senses that the label feeding has started to move and transmits the signal to the secondary electromagnetic pressure control valve 5. The secondary electromagnetic pressure control valve 5 opens and fills the air storage tank 3 of the steering guide rail 1 with air, while simultaneously venting the air from the air outlet. The secondary electromagnetic pressure control valve 5 adjusts its opening according to the pressure monitored in the air storage tank of the steering guide rail 1 to maintain the pressure at a preset threshold. When the label feeds through the steering guide rail 1, the friction coefficient of the steering guide rail 1 is reduced because the surface of the steering guide rail 1 is made of a material with a friction coefficient lower than the preset threshold. At the same time, the friction coefficient of the steering guide rail 1 is further reduced because a coating with a friction coefficient lower than the preset threshold is applied to the surface of the steering guide rail 1, thus preventing the label from breaking. When the label stops moving, the photoelectric sensor 6 senses that the label paper has stopped moving and sends a signal to the secondary electromagnetic pressure control valve 5, which then closes, thus saving gas.
