Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, specifically a small label automatic labeling machine. Background Technique

[0002] A labeling machine is an automated packaging device mainly used for pasting labels on various products or packages. This mechanical equipment can automatically complete the whole process from label feeding, positioning, pasting to the product, and is widely used in many industries such as food, medicine, cosmetics, daily chemicals, electronic products, beverages, etc.; A label is a small identifier with text, patterns or symbols, used to represent specific information of a product or item. Labels can be attached to various items, aiming to transmit information, provide identification or classification. In different application scenarios, the form and function of labels may vary.

[0003] Combined with the labeling machines in the existing technology, it is found that when the labeling machine is in use, the pasting strength of the label is relatively low, and the label often loosens or falls off. During the production process, if the label falls off, remedial operations can be carried out, such as replacing the label. However, during subsequent transportation or sales, the falling off of the label will seriously affect the product. Content of the Utility Model

[0004] The purpose of the utility model is to provide a small label automatic labeling machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A small label automatic labeling machine includes a box body. A conveyor belt is arranged below the box body. A tightening mechanism and a label pasting mechanism are arranged on the left and right sides of the conveyor belt. The tightening mechanism includes a first support plate, a first air blower body, a first air outlet pipe, a first air storage body and a pressing roller. A first support plate is fixedly installed on the outer wall of the right end of the conveyor belt. A first air blower body is fixedly installed at the upper end of the first support plate. A first air outlet pipe is fixedly installed at the left end of the first air blower body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, a tightening mechanism and a label attaching mechanism are provided. The tightening mechanism significantly improves the adhesion strength between the label and the product surface through the double-end air jet structure of the first air blower body and the second air blower body, as well as the physical pressing action of the pressing roller. This dual protection mechanism effectively prevents the loosening and falling off of the label during transportation or sale. Through the cooperation of components such as the support rod and the spring body, the tightening mechanism can maintain stable operation, ensuring the accuracy and consistency of label pasting even on a high-speed production line.

[0026] The working principle of the present utility model is as follows: The small label automatic labeling machine of the present utility model is additionally provided with a tightening mechanism 3 and a label pasting mechanism 4. Before using the small label automatic labeling machine, it is necessary to pre-connect the power supply to the conveyor belt 2, the first air blower body 302, the second air blower body 306 and the motor under the first device plate 401 and connect them to the control terminal. When using the small label automatic labeling machine, first, the first roll tape 403 with the first label body 404 pasted thereon is pre-installed on the first reel 402, and then the other end of the first roll tape 403 is wound around the first storage tray 405. Start the motor under the first device plate 401 to drive the first storage tray 405 to rotate, and then the first roll tape 403 can be pulled, so that the first roll tape 403 moves stably under the guiding effect of the limiting rod on the upper surface of the first device plate 401. When the first roll tape 403 is suddenly bent, the first label body 404 will continuously fall off and be pasted on the box body 1 (the box body 1 is not specified and can be most products, such as milk cartons, paper boxes, etc.). Similarly, the second device plate 406, the second reel 407, the second roll tape 408, the second label body 409 and the second storage tray 410 also perform the above operations to paste the second label body 409 on the other side of the box body 1. At this time, the box body 1 on which the pasting operation is completed will be conveyed under the action of the conveyor belt 2, and the tightening mechanism 3 comes into play. First, the first air blower body 302 and the second air blower body 306 work, and jet air through the air grooves on the first air chamber body 304 and the second air chamber body 308 to form a double-end jet structure, which can make the label body fit more closely on the box body 1 under the action of air pressure. Then, under the action of the double-end pressing roller 311, the label body will fit more tightly on the box body 1. The pressing roller 311 is made of colloid and can effectively press the label body under the action of the spring body 313. To sum up, the tightening mechanism 3 and the label pasting mechanism 4 complement each other. The tightening mechanism 3 adopts a structure of wind pressure and physical pressing. First, the label is quickly pressed by wind pressure, so that the label body fits closely on the box body 1. Subsequently, under the pressing effect of the pressing roller 311, the label body can be tightly attached to the box body 1, ensuring the stability and reliability of label pasting. The label pasting mechanism 4 adopts an automatic labeling structure, which can automatically attach the label body to the box body 1 to achieve the effect of automatic label pasting.
