Description

Technical Field

[0001] This utility model relates to the field of food packaging equipment technology, specifically to a batch packaging bag labeling device. Background Technology

[0002] In modern industrial production, packaging is a crucial link in commodity circulation, and labeling is an indispensable part of the packaging process. Labels not only carry basic product information, such as production date, shelf life, ingredients, and instructions for use, but may also contain important information such as brand promotion and anti-counterfeiting features. Therefore, efficient and accurate labeling is of great significance for improving production efficiency and ensuring product quality.

[0003] In traditional automated labeling devices, a common type uses pressure rollers to press and adhere labels. As a bag passes through, the pressure roller applies pressure to press the label onto the bag's surface. However, this design has a problem: the height of the pressure roller is usually fixed and cannot be adjusted for different bag sizes. Given the wide variety of bag types and sizes on the market, a fixed-height pressure roller cannot meet the labeling needs of all bags. If the bag is small, the label may be over-pressed or even damaged; if the bag is large, the label may not fully cover the bag or may not adhere tightly, leading to label detachment or inaccurate placement. Therefore, we propose a batch-type bag labeling device to solve these problems. Utility Model Content

[0005] A batch packaging bag labeling device, comprising:

[0006] A support plate is symmetrically fixed to the side of the conveyor belt, and a mounting frame is fixed to one side of the support plate;

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a batch packaging bag labeling device, mainly to solve the problem in the prior art that, due to the wide variety of packaging bags on the market and their varying sizes, a fixed-height compression roller cannot meet the labeling needs of all packaging bags. If the packaging bag is small, the label may be over-compressed or even damaged; if the packaging bag is large, the label may not be fully covered or may not adhere tightly, leading to easy label detachment or inaccurate placement. The application provides the following technical solution, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0027] A batch packaging bag labeling device, comprising:

[0028] Support plate 1 is symmetrically fixed on the side of the conveyor belt, and mounting frame 2 is fixed on one side of support plate 1;

[0029] The pressure roller assembly 3 is disposed inside the mounting frame 2 and is used to press the label onto the surface of the packaging bag. The height of the pressure roller assembly 3 is adjustable. The pressure roller assembly 3 includes a U-shaped plate 301 disposed inside the mounting frame 2. An installation rod 302 is rotatably connected between the inner side walls of the U-shaped plate 301. A squeezing roller 303 is fixed in the middle of the installation rod 302. An adjusting rod 304 is threadedly connected to the top center of the mounting frame 2. The bottom end of the adjusting rod 304 is threadedly connected to the top of the U-shaped plate 301 through a bearing.

[0030] Mounting platform 4 is located on the side of support plate 1 away from mounting frame 2, and label release device is located on top of mounting platform 4;

[0031] Guide plate 5 is fixed on the side of the mounting platform 4 near the mounting frame 2. Guide plate 5 is used to guide the labeling.

[0032] The extension plate 6 is fixed upward at an angle on the side of the mounting frame 2 near the mounting platform 4;

[0033] The extrusion mechanism 7 is symmetrically arranged on the side of the extension plate 6 away from the mounting frame 2. The extrusion mechanism 7 is used to press the label.

[0034] It should be noted that a complete packaging bag labeling device, in addition to the components already present in this device, should also include a conveyor belt and a labeling supply device. Both of these devices use existing technologies, and their working principles will not be elaborated upon.

[0035] I. Workflow Description:

[0036] Step 1, Packaging bag delivery:

[0037] The packaging bags are transported to the labeling area by a conveyor belt, and the support plates 1 and mounting frames 2 on both sides of the conveyor belt provide stable support for the main body of the device;

[0038] The label release device (located on top of the mounting platform 4) continuously outputs the label tape, which is then guided into the pressure roller area by the guide plate 5.

[0039] Step 2, Adjusting the height of the pressure roller:

[0040] The operator rotates the adjusting rod 304, which drives the U-shaped plate 301 and the extrusion roller 303 to move up and down as a whole through the threaded transmission to adapt to packaging bags of different heights. When the packaging bag passes under the extrusion roller 303, the extrusion roller 303 applies pressure to press the label onto the surface of the packaging bag. The extrusion mechanism 7 can extrude the second label, causing the foremost label to separate from it.

[0041] Step 3, continuous labeling:

[0042] After the packaging bags have been labeled, they leave the device via a conveyor belt, and the next packaging bag enters, thus achieving batch labeling operations in a cyclical manner.

[0043] This batch packaging bag labeling device differs from the traditional fixed-height squeezing roller 303. The pressure roller assembly 3 of this device can adjust its height according to the size of the packaging bag. Through the threaded linkage design between the adjusting rod 304 and the U-shaped plate 301, the vertical height of the squeezing roller 303 can be precisely adjusted to adapt to packaging bags of different sizes, solving the compatibility problem of traditional fixed pressure rollers and improving the flexibility and accuracy of labeling.

[0044] like Figure 1As shown, in some embodiments, the mounting frame 2 has slotted holes 201 on both sides, and the two ends of the mounting rod 302 are inserted into the slotted holes 201. More specifically, when it is necessary to adjust the height of the extrusion roller 303 to accommodate packaging bags of different sizes, the operator can rotate the adjusting rod 304. The rotation of the adjusting rod 304 will cause the U-shaped plate 301 to move along the height direction of the mounting frame 2 through threaded transmission. Since the two ends of the mounting rod 302 are restricted by the slotted holes 201, it can only move vertically. In this way, the extrusion roller 303 fixed in the middle of the mounting rod 302 will rise or fall to the required height position. Once the appropriate height is reached, the rotation of the adjusting rod 304 can be stopped, and the locking device can be used to keep the position of the extrusion roller 303 unchanged.

[0045] like Figure 4 As shown, in some embodiments, the guide plate 5 is arc-shaped. More specifically, the arc-shaped guide plate 5 can more effectively guide the label to adhere to the surface of the packaging bag. Since the packaging bag may experience slight offset or wobbling during movement, the arc-shaped design can provide a more stable and accurate guiding effect, ensuring that the label will not be misattached due to deviation from the target position.

[0046] like Figure 4 As shown, in some embodiments, a limiting roller 8 is also included. A fixed plate 9 is connected to the middle of both sides of the guide plate 5. The limiting roller 8 is rotatably connected between the fixed plates 9 via a rotating shaft. More specifically, during the labeling process, when the label contacts and is pressed against the packaging bag, the limiting roller 8 plays a crucial limiting role. It ensures that the label does not excessively flip outwards after being pressed by the extrusion roller 303. The limiting roller 8 not only prevents the label from flipping outwards but also helps in the precise guidance and positioning of the label. During label release and application, the limiting roller 8 ensures that the label moves along a predetermined path, reducing offset and errors.

[0047] like Figure 4As shown, in some embodiments, the extrusion mechanism 7 includes a mounting cylinder 701 fixedly embedded in the surface of the extension plate 6. An electromagnet 702 is mounted on the mounting cylinder 701 near its inner top wall. A limiting ring 703 is fixed inside the mounting cylinder 701. A slide rod 704 is slidably inserted inside the limiting ring 703. An armature 705 is fixed at one end of the slide rod 704 near the electromagnet 702. A movable disk 706 is fixed on the surface of the slide rod 704. A spring 707 connects the movable disk 706 and the limiting ring 703. The slide rod 704 is positioned away from the armature. One end of the armature 705 extends outward from the mounting cylinder 701. More specifically, when the electromagnet 702 is energized, the armature 705 is attracted, causing the slide rod 704 to move towards the electromagnet 702. The slide rod 704 moves linearly within the limiting ring 703. At this time, the spring 707 is compressed, and one end of the armature 705 of the slide rod 704 separates from the label, preparing for the next squeezing action. When the electromagnet 702 is de-energized, the elastic force of the spring 707 will cause the slide rod 704 to move outward to squeeze the label, causing the second label to separate from the first label.

[0048] like Figure 4 As shown, in some embodiments, a rubber ball 708 is provided at one end of the slide bar 704 located outside the mounting cylinder 701. More specifically, the rubber ball 708 is typically made of a wear-resistant and highly elastic rubber material. This material has good flexibility and cushioning properties, and can effectively absorb and disperse pressure, thereby protecting the label and packaging bag from damage during the labeling process.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
