[0001] This utility model belongs to the technical field of auxiliary equipment for metal product processing, and in particular relates to a labeling device for metal products. Background Technology

[0002] In the metal processing and manufacturing industry, metal products must be labeled with specifications, parameters, production information, etc. before leaving the factory. The quality of labeling directly affects the product's recognizability and the standardization of market circulation.

[0003] Existing labeling equipment is prone to label misalignment and wrinkling during the unwinding and peeling processes when labeling metal products. This leads to misalignment between the label and the metal surface during application, affecting the consistency of the product's appearance. Finally, the adhesion of the label after application is difficult to guarantee. Secondly, existing labeling equipment can only adapt to labels of a single width and cannot be changed to different widths according to actual requirements, resulting in poor adaptability. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a metal product labeling device, which aims to solve the problems of poor labeling effect of existing metal product labeling devices and the inability to change labels of different widths according to actual requirements.

[0005] The present invention adopts the following technical solution:

[0006] The metal product labeling device includes a machine base, with a rotary motor and a carrier frame positioned at the front and rear of the machine base, respectively. The drive shaft of the rotary motor is equipped with a rotating table, and a pair of feeding seats are spaced apart on the rotating table. Limiting holes and placement openings are respectively opened at the front and rear of the feeding seats.

[0008] Furthermore, the carrier has a base, and the clamping assembly includes a rubber wheel rotatably mounted on the base. The side wall of the base has a forward-facing and upward-facing inclined groove behind the rubber wheel. A slide is embedded in the inclined groove, and a pressure wheel is rotatably mounted in the slide. A short plate is provided at the bottom of the inclined groove on the side wall of the base, and an adjusting stud is screwed into the short plate. The end of the adjusting stud abuts against the back of the slide.

[0019] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0022] Combination Figure 1-4 As shown, the metal product labeling device includes a machine base 1. A rotary motor 2 and a carrier frame 3 are respectively provided at the front and rear positions of the machine base 1. The drive shaft of the rotary motor 2 is provided with a rotary table 4. A pair of feeding seats 5 are spaced apart on the rotary table 4. The feeding seats 5 have limit holes 6 and placement openings 7 at their front and rear, respectively. The carrier frame 3 is sequentially provided with a winding wheel 9, a guide wheel 10, a label tearing component, a labeling component, a pressing component, and a rotatable winding wheel 11. The labeling component includes a fixed seat 12 mounted on the carrier frame 3. A lifting cylinder 13 is vertically provided on the fixed seat 12. A lifting plate 14 is slidably provided on the lifting cylinder 13. The drive shaft of the lifting cylinder 13 is connected to the bottom of the lifting plate 14. A connecting plate 15 is provided on the lifting plate 14. The bottom surface of the connecting plate 15 and the front and rear are respectively provided with limit pins 16 and vacuum nozzles 17. The limit pins match the limit holes.

[0023] This device can be used to label metal products before they leave the factory, using labels to indicate the specifications, parameters, production information, etc.

[0024] In this device Figure 3 In the process, the material feeding seat 5 has notches 18 on both sides of the placement opening 7. By setting the notches, it is convenient to place the metal products into the placement opening, and it is also convenient to remove the metal products from the placement opening after they have been labeled.

[0025] When using this device to label metal products, the metal product to be labeled is first placed in the placement opening of the feeding seat. Simultaneously, the unwinding roller releases the label tape, which, guided by the guide roller, enters the label-tearing assembly. Under the action of the label-tearing assembly, the label separates from the label base. At this point, the lifting cylinder drives the lifting plate to descend, and the vacuum suction nozzle on the bottom surface of the connecting plate picks up the separated label. The lifting cylinder then drives the lifting plate to rise again. Subsequently, the rotary table rotates, rotating the feeding seat containing the metal product to the labeling position. The lifting cylinder again drives the lifting plate to descend until the vacuum suction nozzle affixes the label to the metal product. Simultaneously, the limiting pin on the bottom surface of the connecting plate inserts into the limiting hole of the feeding seat, positioning the feeding seat and ensuring accurate labeling.

[0026] Then, the lifting cylinder drives the lifting plate to move upward, completing one labeling action. The rotary motor drives the rotary table to rotate at a certain angle, so that the metal products on the next feeding seat enter the labeling position and wait for labeling, while the metal products that have been labeled are taken out.

[0027] In addition, such as Figure 4 In the process, the carrier 3 has a carrier seat 19, and a limiting component is provided on the carrier seat 19 behind the label tearing component. In actual operation, the label tape passes through the limiting component and the label tearing component in sequence. The limiting component includes a fixing plate 20, and a stop block 21 is formed by the protrusion on the left side of the fixing plate 20. An adjusting plate 22 is provided at the upper limit of the fixing plate 20. The stop block 21 and the adjusting plate 22 are arranged to the left and right. An oblong groove 23 is opened on the adjusting plate 22, and a locking screw 24 is inserted into the oblong groove 23. The end of the locking screw 24 is screwed into the fixing plate 20. A limiting cylinder 25 is also provided on the fixing seat. A limiting seat 26 is provided on the drive shaft of the limiting cylinder 25. The limiting seat 26 is located between the stop block 21 and the adjusting plate.

[0028] In this structure, the distance between the adjusting plate and the stop block can be changed by adjusting the position of the locking screw within the oblong groove, thus accommodating label tapes of different sizes. The adjusting plate and the stop block are distributed on the left and right sides of the label tape, limiting its lateral movement and achieving horizontal restriction. Simultaneously, the limiting cylinder drives the limiting seat to contact the label tape without pressing it down, thus limiting the label tape vertically and improving labeling accuracy.

[0029] As a preferred structure, the label-tearing assembly includes a label-tearing carrier plate 27 mounted on a carrier frame. The label-tearing carrier plate is provided with a pair of left and right limiting plates 28, wherein the left limiting plate is fixedly installed and the right limiting plate is slidably installed. The right limiting plate has an adjustment groove 29, and an adjustment screw 30 is inserted into the adjustment groove. The end of the adjustment screw is screwed into the label-tearing carrier plate.

[0030] Similarly, the distance between the right and left limiting plates can be adjusted by changing the position of the adjusting screw within the adjusting slot, thus accommodating the label-tearing requirements of labels of different widths. During the label-tearing process, the label passes between the two limiting plates and is separated from the backing paper by the action of the label-tearing carrier plate.

[0031] As a specific structure, combined Figure 2-3 In the process, the clamping assembly includes a rubber wheel 31 rotatably mounted on a carrier. The side wall of the carrier has a forward-facing and upward-facing inclined groove 32 located behind the rubber wheel. A slide 33 is embedded in the inclined groove. A pressure wheel 34 is rotatably mounted in the slide. A short plate 35 is provided on the side wall of the carrier 19 at the bottom of the inclined groove. An adjusting stud 36 is screwed into the short plate, and the end of the adjusting stud abuts against the back of the slide.

[0032] In the aforementioned label-tearing process, the label and backing paper are separated under the action of the label-tearing carrier plate. The backing paper passes through the pressing component and is then retracted onto the unwinding roller. Specifically, after the label and backing paper are separated, the backing paper passes through the adhesive roller and pressure roller, and finally winds onto the take-up roller. In this embodiment, when the adjusting stud is rotated, the adjusting stud pushes the slide forward in the inclined groove, and the pressure roller moves towards the adhesive roller, which can change the height and pressure of the pre-pressure roller to meet the requirements of labels of different thicknesses. This ensures that the pressure roller and adhesive roller can always press the backing paper tightly, further improving the labeling quality.

[0033] like Figure 1 In this configuration, the carrier also has a rotating wheel 37, and a driving wheel 38 is mounted on the axle of the rotating wheel. A drive motor (located inside the carrier and obscured in the figure) is installed inside the frame to drive the rotating wheel's rotation. A driven wheel 40 is mounted on the axle of the take-up wheel 11. A belt 41 is fitted onto both the driving and driven wheels. The driving motor drives the rotating wheel to rotate, which in turn causes the take-up wheel to rotate via the belt drive, thus achieving the winding of the label backing paper.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
