Description

Technical Field

[0001] This utility model relates to the technical field of labeling devices, and in particular to a labeling device. Background Technology

[0002] A labeling machine is a device that affixes rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. Labeling machines are an indispensable component of modern packaging. Currently, the variety of labeling machines produced in my country is gradually increasing, and the technological level has also greatly improved. The industry has shifted from the outdated manual and semi-automatic labeling methods to a market dominated by automated, high-speed labeling machines.

[0003] Chinese utility model CN214397610U describes a replaceable adsorption structure for labeling machines. It includes an adsorption strip replacement device that uses multiple bolts to connect the adsorption strip to the connecting block, then uses a fixing part and clamping to clamp the fixing rod, and finally uses a screw to fix it and stabilize it.

[0004] However, existing devices require tools to install multiple bolts, making the process cumbersome and inconvenient. Therefore, an adsorption structure that is easier to install was designed to address the aforementioned problems. Utility Model Content

[0026] The current technology involves using multiple bolts to connect the adsorption strip to the connecting block, then using a fixing part and clamps to hold the fixing rod, and finally using screws to fix it securely. However, the existing device requires tools to install multiple bolts during installation, which is cumbersome and inconvenient.

[0027] As shown in the attached drawings, this embodiment of the present invention provides a labeling device.

[0028] The labeling machine body 11 includes: a crossbar 12 at the top, which is connected to an air pump on the labeling machine body 11; an adsorption strip 13 at the bottom of the crossbar 12; and a connecting assembly 2 at one end of the crossbar 12, which includes: a tube 21 fixedly disposed at the bottom of one end of the crossbar 12; a telescopic tube 22 fixedly disposed inside the tube 21, with its top end connected to an air pipe on the crossbar 12; a spring 23 sleeved on the outside of the telescopic tube 22, with its top end fixedly connected to the inner wall of the tube 21; a retaining ring 24 fixedly sleeved on the outer wall of the bottom end of the telescopic tube 22, with its top end connected to the bottom end of the spring 23; an air pipe 25 embedded inside the adsorption strip 13; a groove 26 formed on the outer wall of the tube 21; and a protrusion 27 fixedly disposed on the outer wall of the adsorption strip 13.

[0029] Specifically, the working principle of the labeling machine body 11 mainly includes the following steps:

[0030] Label peeling: After leaving the conveyor belt, the label is attracted to a vacuum pad. This vacuum pad is connected to a mechanical device that extends until the label comes into contact with the product, then quickly retracts to attach the label to the product.

[0031] High-precision labeling: The vacuum labeling method is known for its high-precision labeling capabilities, making it particularly suitable for labeling complex packaging products. By precisely controlling the adsorption and release of the vacuum pad, accurate label positioning and attachment can be achieved.

[0032] Applicable scenarios: The suction method is suitable for products of various shapes and materials, and is especially suitable for occasions where high labeling accuracy is required. For example, for labeling curved or irregularly shaped products, the suction method can provide higher labeling quality and stability.

[0033] The aforementioned conveyor belt is existing technology and is not shown in the accompanying drawings.

[0034] When installing the adsorption strip 13, first insert the top of the adsorption strip 13 into the inside of the tube 21. At the same time, insert the protrusion 27 into the inside of the slide groove 26. Then, when the protrusion 27 is inserted into the top of the slide groove 26, the top of the air pipe 25 will connect with the bottom of the telescopic pipe 22. At the same time, push the retaining ring 24 to move upward, so that the spring 23 is compressed. Then control the rotation of the adsorption strip 13 so that the protrusion 27 slides inside the slide groove 26. Then release the adsorption strip 13, the spring 23 rebounds and pushes the air pipe 25 downward, so that the adsorption strip 13 moves downward. At the same time, the protrusion 27 is inserted into the inside of the slide groove 26 to complete the installation. At this time, the air pump on the labeling machine body 11 can control the suction of the adsorption strip 13 through the pipe in the crossbar 12, the telescopic pipe 22 and the air pipe 25. The label can be picked up from the conveyor belt and then attached to the workpiece by the robotic arm.

[0035] In some embodiments, the groove 26 and the protrusion 27 are provided in two sets.

[0036] It has two sets of features to increase the strength of the connection and make it less likely to separate.

[0037] In some embodiments, the connecting component 2 further includes a rubber head 28 fixedly disposed on the top of the air tube 25.

[0038] The design of the rubber head 28 reduces the gap when the top of the air tube 25 is connected to the bottom of the telescopic tube 22, thus preventing gas loss.

[0039] In some embodiments, the connecting assembly 2 further includes: the top end of the upright 29 passes through the retaining ring 24 and is fixedly connected to the inner side wall of the top end of the tube 21.

[0040] The design of the upright 29 can stabilize the up and down movement of the retaining ring 24, thereby preventing the spring 23 and the telescopic tube 22 from bending.

[0041] In some embodiments, a limiting component 3 is provided on the outer side wall of the tube body 21. The limiting component 3 further includes: a positioning hole 31 formed on the outer side wall of the tube body 21; a ring body 32 sleeved on the outer side of the tube body 21; a housing 33 fixedly disposed on the outer side wall of the ring body 32; a second spring 34 fixedly disposed inside the housing 33; one end of a plug rod 35 passing through the ring body 32 and inserted into the inside of the housing 33 and connected to the second spring 34; and one end of a pull rod 36 passing through the housing 33 and connected to the plug rod 35.

[0042] After installation, to ensure stability, pull rod 36 can be pulled out from inside housing 33, causing insert rod 35 to be inserted into housing 33. Spring 34 is compressed, and insert rod 35 is pulled out from positioning hole 31 to release the restriction on ring 32. Then, push ring 32 to slide downward on the outside of tube 21 until insert rod 35 is aligned with positioning hole 31. Then release pull rod 36, spring 34 rebounds and pushes insert rod 35 out from inside housing 33 and into positioning hole 31 to stabilize the position of ring 32. Ring 32 can restrict protrusion 27 from sliding inside groove 26.

[0043] In some embodiments, the limiting component 3 further includes a tension torque 37 fixedly disposed at one end of the pull rod 36.

[0044] The design of the pull knob 37 makes it easy to grip and control the movement of the pull rod 36.

[0045] In some embodiments, the limiting component 3 further includes: a groove 38 formed on the inner side of the ring 32; and a protrusion 39 fixedly disposed on the outer side wall of the tube 21.

[0046] The design of the groove 38 and the ridge 39 can stabilize the ring 32 sliding on the outside of the tube 21 and prevent the ring 32 from rotating so that the insertion rod 35 and the positioning hole 31 are kept on the same horizontal line.

[0047] In some embodiments, the limiting component 3 further includes: a stop 391 fixedly disposed at both ends of the protrusion 39.

[0048] The design of the stop 391 can prevent the ring 32 from separating from the protrusion 39.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
