Description

Technical Field

[0001] This utility model relates to the field of labeling suction head technology, specifically a labeling machine suction head assembly. Background Technology

[0002] Labeling machines are production equipment that uses adhesives to affix labels of paper or other materials to product packaging containers. They are an indispensable piece of equipment in modern packaging processes. Currently, existing labeling machines typically consist of a labeling mechanism and a suction head structure. The labeling mechanism controls the suction head structure to move above the label, then drives the suction head structure to press down, adhering the label held by the suction head to the label. Existing labeling machines can only affix one label at a time because the suction head can only pick up one label at a time, thus affecting production efficiency.

[0003] A labeling machine suction head with application number 201921670147.6 in the prior art includes a suction tube, which comprises an outer tube and an inner core tube. The upper end of the outer tube is open and connected to an external negative pressure air source. The upper end of the inner core tube is fitted inside the lower end of the outer tube to form a connecting sleeve. The lower end of the inner core tube is connected to a main suction pipe. Multiple suction nozzles are provided on the lower outer side of the main suction pipe, and the suction nozzles are connected to a suction cup head. The suction cup head adsorbs labels through the negative pressure in the suction tube and the main suction pipe. This utility model adopts a labeling machine suction head structure with multiple suction cup heads, which can adsorb multiple labels of the same or different shapes at a time, and has the characteristics of high production efficiency. However, the labeling and suction angles cannot be adjusted, and the operation of feeding or labeling multiple labels is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a labeling machine suction head assembly to solve the problems in the prior art where the angle of labeling and suction cannot be adjusted, and the operation of feeding or labeling multiple labels is inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a labeling machine suction head assembly, including an upper bracket, a labeling roller rotatably mounted on the lower side of the upper bracket via a connecting shaft, a motor being connected to one end of the connecting shaft via a gear set, a plurality of support plates arranged in a circular array on the outer side of the labeling roller, and a suction plate being provided between two support plates via an elastic telescopic mechanism, and a pneumatic suction cup being provided on the suction plate via a support rod.

[0006] Furthermore, the upper end of the upper bracket is provided with a mounting plate, and the mounting plate has mounting holes inside both ends.

[0007] Furthermore, the gear set includes a driven gear disposed at one end of the connecting shaft, and a driving gear that meshes with the driven gear is disposed at one end of the motor.

[0008] Furthermore, the motor is a stepper motor, and the motor is fixedly mounted on the outer wall of the upper bracket via a base.

[0009] Furthermore, the elastic telescopic mechanism includes a limiting groove disposed on the inner wall of one end of the support plate, and the two ends of the suction plate are slidably disposed with the limiting groove via limiting sliders.

[0010] Furthermore, the limiting groove is also provided with a guide rod that slides with the limiting slider, and a spring is sleeved on the end of the guide rod away from the outer pneumatic suction cup.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features a labeling roller rotatably mounted on the lower side of the upper support via a connecting shaft, and a pneumatic suction cup mounted on the outer side of the labeling roller via a support plate and a suction plate. This allows the labeling roller to be driven to rotate longitudinally by a motor and gear set, thereby holding multiple labels outside the labeling roller. Multiple labels can be moved to the lower part of the labeling roller for labeling processing, enabling the feeding or labeling of multiple labels at once. The angle of labeling and suction can also be adjusted, which improves the efficiency of the labeling machine.

[0013] 2. In this utility model, the suction plate is set at one end of two support plates through an elastic telescopic mechanism. The elastic telescopic mechanism includes a limiting groove set on the inner wall of one end of the support plate, and the two ends of the suction plate are slidably set with the limiting groove through limiting sliders. A spring is sleeved on the end of the guide rod away from the outer pneumatic suction cup. This allows the elastic telescopic mechanism to perform elastic pressing treatment when the suction plate is loaded and unloaded, which is beneficial to improve the stability of the pneumatic suction cup in holding the label. At the same time, it can provide elastic buffering treatment when labeling to prevent damage to the product or label during hard labeling. Attached Figure Description

[0020] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the present invention, a labeling machine suction head assembly includes an upper bracket 1. An mounting plate 10 is provided at the upper end of the upper bracket 1, and mounting holes 11 are provided at both ends of the mounting plate 10 to facilitate the installation and fixing of the equipment. A labeling roller 2 is rotatably mounted on the lower side of the upper bracket 1 via a connecting shaft 3. One end of the connecting shaft 3 is connected to a motor 5 via a gear set. Multiple support plates 7 are arranged in a circular array on the outer side of the labeling roller 2, and a suction plate 9 is provided between two support plates 7 via an elastic telescopic mechanism. A pneumatic suction cup 8 is provided on the suction plate 9 via a support rod. The gear... The assembly includes a driven gear 6 at one end of the connecting shaft 3, and a driving gear 4 at one end of the motor 5 that meshes with the driven gear 6. The motor 5 is a stepper motor and is fixedly mounted on the outer wall of the upper support 1 via a base. This allows the labeling roller 2 to be driven to rotate longitudinally by the motor 5 and the gear assembly, thereby holding multiple labels on the outside of the labeling roller 2. At the same time, multiple held labels can be moved to the lower part of the labeling roller 2 for labeling processing. Multiple labels can be fed or labeled at one time, which is beneficial to the labeling efficiency of the labeling machine.

The elastic telescopic mechanism includes a limiting groove 12 set on the inner wall of one end of the support plate 7, and a spring 15 is sleeved on the end of the guide rod 14 away from the outer pneumatic suction cup 8. The two ends of the suction plate 9 are slidably set with the limiting groove 12 through the limiting slider 13. This allows the elastic telescopic mechanism to provide elastic pressing treatment when the suction plate 9 is loading and unloading, which helps to improve the stability of the pneumatic suction cup 8 in holding the label. At the same time, it can provide elastic cushioning treatment during labeling to prevent damage to the product or label during hard labeling.

[0022] like Figure 3 As shown, in order to improve the stability of the extension and retraction adjustment of the suction plate 9, a guide rod 14 is also provided inside the limiting slide groove 12, which is slidably arranged with the limiting slider 13. This guide rod is used to slide and guide the limiting slider 13 during the lifting and lowering adjustment, which helps to improve the stability of the extension and retraction adjustment of the suction plate 9.

[0023] The working principle and usage process of this utility model are as follows: In use, the equipment is installed on the labeling machine frame via the upper bracket 1. The labeling roller 2, which is rotatably mounted on the lower side of the upper bracket 1 via the connecting shaft 3, is provided with a pneumatic suction cup 8 on the outer side of the labeling roller 2 via the support plate 7 and the suction plate 9. The labeling roller 2 is driven to rotate longitudinally by the motor 5 and the gear set, thereby holding multiple labels on the outside of the labeling roller 2. At the same time, multiple held labels can be moved to the lower part of the labeling roller 2 for labeling processing. Multiple labels can be fed or labeled at one time, which is beneficial to the labeling efficiency of the labeling machine.
