Description

Technical Field

[0001] This utility model belongs to the field of labeling machine technology, and in particular relates to an automatic labeling machine. Background Technology

[0002] In automated production in industries such as packaging and electronics, automatic labeling machines are the core equipment for affixing product labels, and their labeling accuracy and efficiency directly affect product quality and production pace.

[0003] Currently available automatic labeling machines still have many technical pain points in practical applications: on the one hand, the traction components mostly adopt a fixed pressure structure, which makes it difficult to quickly adjust the bonding pressure between the pressure roller and the traction roller when the material or thickness of the label tape changes, easily causing the label tape to slip or break, resulting in labeling interruption; on the other hand, the vacuum suction head of the labeling component directly adsorbs the label, which cannot guarantee that the label can be stably picked up every time, reducing the labeling quality. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide an automatic labeling machine, which aims to solve the problems that existing automatic labeling machines cannot adapt to changes in the thickness of the label tape and have low labeling quality.

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

[0006] The automatic labeling machine includes a labeling base, on which are sequentially arranged an unwinding wheel, a label-tearing assembly, a labeling assembly, a reversing wheel, a traction assembly, and a take-up wheel. The traction assembly includes a traction wheel. The labeling base has adjusting seats at positions before and after the traction wheel. The adjusting seats are rotatably mounted on an adjusting bracket via a torsion spring. The adjusting bracket is rotatably mounted on a pressure wheel. The adjusting seat has a slot, and an eccentric wheel is rotatably mounted in the slot. The middle of the adjusting bracket is positioned opposite the eccentric wheel. The shaft of the eccentric wheel extends out of the adjusting seat and has a rotating head. A traction motor is located on the back of the labeling base, which drives the traction wheel to rotate.

[0007] Furthermore, the label-tearing assembly includes a label-tearing plate with a limiting groove. A limiting component is provided on the front side of the label-tearing plate. The limiting component includes a side plate and a support plate arranged vertically. A limiting plate is slidably arranged on the side plate. A limiting cylinder is provided above the side plate. The drive shaft of the limiting cylinder is connected to the top of the limiting plate.

[0008] Furthermore, the labeling assembly includes a slide rail, a slide base on the slide rail, a lifting cylinder on the slide base, a connecting plate slidably mounted on the lifting cylinder, and the drive shaft of the lifting cylinder connected to the connecting plate. A slide plate is mounted on the connecting plate, and a vacuum suction head is mounted at the bottom of the slide plate. A labeling cylinder is mounted on the back of the labeling base, and the drive shaft of the labeling cylinder is connected to the slide base.

[0009] Furthermore, the slide plate is slidably mounted on the connecting plate, the connecting plate is provided with a top plate, the top of the slide plate is provided with a guide rod, the guide rod extends out of the top plate and is limited and mounted on the top plate, and a spring is provided on the guide rod between the top plate and the slide plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. The traction component of this device, through the design of the eccentric wheel and the adjusting bracket, can easily and quickly adjust the distance between the pressure wheel and the traction wheel, adapt to the stable traction of label tapes of different thicknesses, and ensure that the label tape does not slip or deviate during transmission, thereby improving the stability and efficiency of labeling.

[0012] 2. After the vacuum suction head picks up the separated label, the lifting cylinder drives the connecting plate to descend. The connecting plate continues to move down a short distance, and the spring is further compressed. In this way, the vacuum suction head has a certain elastic force when picking up the label, ensuring the reliability of label picking up. Attached Figure Description

[0017] 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.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0020] Combination Figure 1-4As shown, the automatic labeling machine includes a labeling base 1, on which are sequentially arranged an unwinding wheel 2, a label tearing assembly, a labeling assembly, a reversing wheel 3, a traction assembly, and a take-up wheel 4. The traction assembly includes a traction wheel 5. The labeling base 1 is provided with adjusting seats 6 at both the front and rear positions opposite to the traction wheel 5. The adjusting seat 6 is rotatably provided with an adjusting bracket 7 via a torsion spring (not shown in the figure). The adjusting bracket 7 is rotatably provided with a pressure wheel 8. The adjusting seat 6 has a slot 61, and an eccentric wheel 9 is rotatably provided in the slot 61. The middle part of the adjusting bracket 7 is provided with a contact plate 10 opposite to the eccentric wheel 9. The shaft of the eccentric wheel 9 passes through the adjusting seat and is provided with a rotating head 11. The back of the labeling base 1 is provided with a traction motor 12, which is used to drive the traction wheel to rotate.

[0021] In this device, the back of the labeling holder is equipped with a rotary motor 29 for driving the take-up reel and the unwind reel to rotate. When using this device, the label tape roll is installed on the unwind reel, and the label tape is pulled through the label tearing assembly, the labeling assembly, the reversing wheel, and the traction assembly in sequence, and finally fixed on the take-up reel.

[0022] When the label tape needs to pass through the traction assembly, simply rotate the front and rear rotating heads in sequence to move the pressure roller a short distance away from the traction roller, creating a gap. The label tape will then pass through the gap between the pressure roller and the traction roller. Once the label tape has passed through the corresponding gap, release the rotating head. The adjusting bracket at that position will reset under the force of the torsion spring, and the pressure roller on the adjusting bracket will press against the traction roller.

[0023] In practical use, the torsion spring ensures that the pressure roller fits tightly against the traction roller, applying pressure to the label tape and ensuring stable transmission of the label tape during traction. The pressure between the pressure roller and the traction roller can also be adjusted using the torsion spring to accommodate label tapes of different materials and thicknesses. When the rotating head is turned, it drives the eccentric wheel to rotate. The eccentric wheel presses against the contact plate, causing the adjusting bracket to rotate around the torsion spring, thus moving the pressure roller a short distance away from the traction roller and creating a gap.

[0024] In this structure, combined Figure 1 as well as Figure 4 The label-tearing assembly includes a label-tearing plate 13, a limiting groove 14 on the label-tearing plate 13, a limiting component on the front side of the label-tearing plate 13, the limiting component includes a side plate 15 and a support plate 16 arranged vertically, a limiting plate 17 is slidably arranged on the side plate 15, a limiting cylinder 18 is arranged above the side plate 15, and the drive shaft of the limiting cylinder 18 is connected to the top of the limiting plate 17.

[0025] In using this device, the limiting cylinder drives the limiting plate to descend, slightly pressing down to contact the label tape. The limiting plate and support plate are located on the upper and lower sides of the label tape, respectively, and limit the vertical movement of the label tape. The label tape is located in the limiting groove on the label-tearing plate, and the limiting groove limits the horizontal movement of the label tape.

[0026] like Figure 4 The labeling assembly includes a slide rail 19, a slide base 20 on the slide rail 19, a lifting cylinder 21 on the slide base 20, a connecting plate 22 slidably mounted on the lifting cylinder 21, and the drive shaft of the lifting cylinder 21 connected to the connecting plate 22. A slide plate 24 is mounted on the connecting plate 22, and a vacuum suction head 25 is mounted at the bottom of the slide plate 24. A labeling cylinder 26 is mounted on the back of the labeling base 1, and the drive shaft of the labeling cylinder 26 is connected to the slide base.

[0027] Subsequently, two rotary motors slowly rotate the take-up and unwind reels, respectively, while a traction motor drives the traction wheel and unwind reel to unwind the label tape. The traction wheel conveys the label tape, and the take-up reel rewinds it. During the label tape conveying process, the label-tearing plate separates the label from the base tape. The labeling cylinder drives the slide to move along the rail above the label, and the lifting cylinder drives the connecting plate to descend. The vacuum suction head then picks up the separated label. The slide then moves up above the product to be labeled, the lifting cylinder continues to descend, and the vacuum suction head releases the label, completing the labeling process.

[0028] As a preferred structure, Figure 4 In this configuration, the sliding plate 24 is slidably mounted on the connecting plate 22, which has a top plate 23. A guide rod 27 is located at the top of the sliding plate 24, extending through the top plate 23 and positioned on the top plate. A spring 28 is mounted on the guide rod 27 between the top plate and the sliding plate. When the vacuum suction head picks up the separated label, a lifting cylinder drives the connecting plate downwards. The vacuum suction head then picks up the separated label, and the connecting plate continues to move downwards a short distance, further compressing the spring. This provides the vacuum suction head with a certain elastic force when picking up the label, ensuring reliable label pickup.

[0029] 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.
