Description

Technical Field

[0001] This utility model relates to the field of label printing equipment technology, and in particular to a label printing and labeling machine with automatic label feeding. Background Technology

[0002] A print and apply labeler is an automated device that integrates label printing and automatic labeling functions. It is widely used in industries such as logistics, packaging, food, pharmaceuticals, and electronics. It can print labels containing variable information (such as barcodes, QR codes, production dates, batch numbers, etc.) in real time according to system instructions and automatically and accurately affix the labels to products or packaging, achieving efficient and accurate labeling operations.

[0003] However, existing label printing machines generally use a single-roll label tube feeding mode, which has the following limitations: when the labels are exhausted, the empty tube needs to be manually removed and replaced with a new one, and the label conveying path needs to be recalibrated; more importantly, the equipment must be stopped during the replacement process, resulting in interruption of production continuity and a significant reduction in overall operating efficiency.

[0004] To address this issue, we propose an automatic label feeding printing and labeling machine to solve the problems of difficult label feeding and low work efficiency in existing technologies. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a label printing and labeling machine with automatic label feeding, so as to solve the problems of difficult label feeding and low work efficiency in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides an automatic label printing and labeling machine, comprising: a machine body and a feeding component, wherein the feeding component is located at the left end of the machine body;

[0007] The feeding assembly includes a housing, inside which are provided two feeding racks for mounting external label rolls. Each feeding rack has a clip below it for clamping the end of the external label roll. An adhesive is provided between the two clips for bonding the two label rolls together. Inside the housing are two push-pull members, each for pushing the feeding rack and clip on the same side back and forth.

[0008] Preferably, the adhesive device includes two symmetrical vertical tracks on the housing. An electric push rod is provided on the outer wall of the housing and at the bottom of the vertical tracks. The upper end of the electric push rod is connected to a horizontal slide rail. The interior of the horizontal slide rail is provided with two symmetrical grooves. A slider is connected inside each groove. A rubber rod is connected to the outer wall of the slider. Each rubber rod passes through a vertical track and extends into the interior of the housing.

[0009] Preferably, the upper end of the vertical track is arc-shaped, and the distance between the tops of the two vertical tracks is greater than the distance between the two clamps.

[0010] Preferably, each side of the feeding rack and the rear end of the clamp are connected to a back plate. The clamp includes two clamping plates. Each clamping plate is connected to a push block at its rear end. The bottom front end of the back plate is provided with two movable grooves that match the push blocks. Each push block can slide left and right in the corresponding movable groove. A spring is connected between the opposite sides of the two push blocks and the inner sidewall of the corresponding movable groove.

[0011] Preferably, each of the feeding racks is provided with a positioning component inside, and each positioning component includes a guide rod. Several connecting rods are connected to both sides of the guide rod, and an extrusion block is connected to the end of the connecting rod. The extrusion block passes through the feeding rack and is slidably connected to the feeding rack. A spring is connected between one end of the guide rod and the inner wall of the feeding rack, and a magnetic block is connected to the other end of the guide rod. An electromagnet is provided on the inner wall of the feeding rack.

[0012] Preferably, each of the push-pull components includes a limiting plate, several pillars, a frame, and a baffle. All the pillars penetrate the back plate and are fixedly connected to the back plate. The rear ends of all the pillars penetrate the housing and are connected to the limiting plate. The front ends of all the pillars are connected to the frame, and the front ends of the frame are connected to the baffle.

[0013] Preferably, the front end of the housing has two openings that match the baffle, and a latch is provided between the housing and the baffle.

[0014] Preferably, a limiting plate is connected to the rear side wall of the baffle, and the limiting plate and the feeding rack on the same side are located on the same center line.

[0015] As described above, the label printing and labeling machine with automatic label feeding disclosed in this utility model has the following beneficial effects: This utility model sets up two feeding racks for alternating between two label rolls, and then clamps the ends of the label rolls to make the label rolls within the range of motion of the adhesive. The adhesive then glues and fixes the two label rolls together, achieving the effect of automatic label feeding, reducing manual operation and improving work efficiency.

[0016] Meanwhile, this utility model also includes a positioning component inside the feeding rack. By using an electromagnet to attract a magnetic block, the guide rod moves. The guide rod pushes the extrusion block to move outward of the feeding rack via a connecting rod, extruding and positioning the inner wall of the label roll. This prevents the label roll from being accidentally pulled during the feeding process, which could affect the bonding and fixing of the two label rolls.

[0017] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0032] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0033] Please see Figures 1 to 7 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0034] like Figure 1-7 As shown, this utility model provides an automatic label printing and labeling machine, including: a machine body 1 and a feeding component 2, the feeding component 2 being located at the left end of the machine body 1. The machine body 1 is the main part of the label printer.

[0035] The feeding assembly 2 includes a housing 20, within which are two feeding racks 21. The feeding racks 21 are used for mounting external label rolls, which are then placed on the feeding racks 21 for feeding. Each feeding rack 21 has a clip 22 at its bottom, which is used to clamp and position the end of the label roll. An adhesive applicator 23 is located between the two clips 22, used to bond the two label rolls together. Inside the housing 20 are two push-pull members 24, each used to move the feeding rack 21 and clip 22 on the same side back and forth, allowing the feeding rack 21 and clip 22 to be removed from the housing 20 for label roll replacement. During the feeding operation, a new label roll is mounted on an unused feeding rack 21. The end of the label roll with adhesive is positioned using the clip 22. The adhesive applicator 23 is used to slide and press the label roll from the surface of the pulled-out portion, causing the end of the label roll to detach from the clip 22 and bond to the tail of another label roll. This structure facilitates automatic label feeding, reduces operational difficulty, improves work efficiency, and avoids the problem of having to stop the machine every time labels need to be fed.

[0036] In one embodiment, please refer to Figure 3 The adhesive applicator 23 includes two symmetrical vertical tracks 230 mounted on the housing 20. An electric push rod 231 is located on the outer wall of the housing 20 at the bottom of the vertical tracks 230. The upper end of the electric push rod 231 is connected to a horizontal slide rail 232. The horizontal slide rail 232 has two symmetrical grooves 233 inside, and each groove 233 is connected to a slider 234. Each slider 234 can slide along its long side within its corresponding groove 233. A rubber rod 235 is connected to the outer wall of each slider 234. Each rubber rod 235 passes through a vertical track 230 and extends into the housing 20. The connection between the rubber rod 235 and the slider 234 is cylindrical, with its diameter slightly equal to the width of the vertical track 230. The rubber rod 235 can rotate around its own centerline. Specifically, the upper end of the vertical track 230 is arc-shaped, the distance between the tops of the two vertical tracks 230 is greater than the distance between the two clamps 22, the diameter of the rubber rod 235 is slightly larger than the distance between the bottom ends of the two vertical tracks 230, and when the rubber rod 235 moves in the arc-shaped stage of the vertical track 230, it can drive the slider 234 to slide in the corresponding groove 233. In the initial stage, the horizontal slide rail 232 is located above the vertical rail 230. During use, by activating the electric push rod 231, the electric push rod 231 drives the vertical rail 230 to descend. The vertical rail 230 drives the rubber rod 235 to move down through the slider 234. The rubber rod 235 slides along the arc-shaped area of ​​the vertical rail 230, causing the two rubber rods 235 to approach and squeeze each other, thereby making the two label rolls stick together. During the descent of the rubber rod 235, the end of the unused label roll is pulled away from the positioning of the clamp 22 and gradually adheres to the other label roll, thereby achieving the adhesion and fixation of the two label rolls and realizing automated feeding operation.

[0037] In one embodiment, please refer to Figure 4 Each side of the loading rack 21 and the rear end of the clamp 22 are connected to a back plate 25. The clamp 22 includes two clamping plates 220. The clamping plates 220 adopt a cylindrical structure to reduce the contact area with the label roll and facilitate release from the clamping of the two clamping plates 220 under stress. Each clamping plate 220 is connected to a push block 221 at its rear end. The front bottom of the back plate 25 is provided with two movable grooves 222 that match the push blocks 221. Each push block 221 can slide left and right in the corresponding movable groove 222. A spring 223 is connected between the opposite side of the two push blocks 221 and the inner side wall of the corresponding movable groove 222. The spring 223 is used to make the two clamping plates 220 stick together through the push blocks 221. When in use, move the clamping plates 220 to both sides to place the end of the label roll with adhesive between the two clamping plates 220. After releasing the clamping plates 220, the two push blocks 221 are pushed closer to each other by the action of the spring 223, and the push blocks 221 drive the clamping plates 220 to clamp and position the end of the label roll.

[0038] In one embodiment, please refer to Figure 6 Each loading rack 21 has a positioning element 26 inside. During the bonding and fixing stage of two label rolls, the label rolls will rotate under the tension of the rubber rod 235 and be fixed by the positioning element 26 to avoid affecting the bonding and fixing operation. Each positioning element 26 includes a guide rod 260, with several connecting rods 261 connected to both sides of the guide rod 260. The end of the connecting rod 261 is connected to an extrusion block 262. One end of the connecting rod 261 is rotatably connected to the guide rod 260, and the other end is rotatably connected to the extrusion block 262, with the two rotating surfaces located in the same plane. The extrusion block 262 passes through the loading rack 21 and is slidably connected to the loading rack 21. A spring 263 is connected between one end of the guide rod 260 and the inner wall of the loading rack 21, and a magnet 264 is connected to the other end of the guide rod 260. An electromagnet 265 is provided on the inner wall of the loading rack 21. When in use, the electromagnet 265 is activated, generating an attractive force to attract the magnetic block 264. The magnetic block 264 drives the guide rod 260 to move, and the guide rod 260 stretches the second spring 263. The guide rod 260 pushes the extrusion block 262 outward through the connecting rod 261, causing the extrusion block 262 to squeeze the inner wall of the label roll, thus fixing the label roll. After the adhesive device 23 is reset, the electromagnet 265 is turned off, releasing the attraction to the magnetic block 264. Under the action of the second spring 263, the guide rod 260 is reset, which in turn causes the extrusion block 262 to retract into the interior of the feeding rack 21, thus releasing the positioning of the label roll.

[0039] In one embodiment, please refer to Figure 7Each push-pull component 24 includes a limiting plate 240, several support columns 241, a frame 242, and a baffle 243. All support columns 241 extend laterally through the back plate 25 and are fixedly connected to it. The rear ends of all support columns 241 extend through the housing 20 and are connected to the limiting plate 240. The front ends of all support columns 241 are connected to the frame 242, and the front ends of the frame 242 are connected to the baffle 243. In use, pulling the baffle 243 moves the support columns 241 through the frame 242. The support columns 241, through the back plate 25, move the loading rack 21 and the clamp 22 forward out of the housing 20. Opening the baffle 243 allows a new label roll to be installed on the loading rack 21, and the end of the label roll is clamped by the clamp 22.

[0040] In one embodiment, please refer to Figure 1 and Figure 7 The front end of the housing 20 has two openings that match the baffle 243, so that the front surface of the baffle 243 is flush with the front surface of the housing 20. A latch 244 is provided between the housing 20 and the baffle 243 to lock the baffle 243 and the housing 20 together.

[0041] In one embodiment, please refer to Figure 7 A limiting plate 245 is connected to the rear side wall of the baffle 243. The limiting plate 245 and the feeding rack 21 on the same side are located on the same center line. After the limiting plate 245 contacts the feeding rack 21, it can be used to limit the position of the label roll.

[0042] The specific usage process of this utility model is as follows:

[0043] Open the latch 244 and pull the baffle 243. The baffle 243 drives the support column 241 to move forward through the frame 242, thereby driving the feeding rack 21 and the clamp 22 to move out of the housing 20.

[0044] Place the label roll onto the feeding rack 21, move the clamps 220 to both sides, place the end of the label roll with adhesive between the two clamps 220, release the clamps 220, and under the action of the spring 223, push the two push blocks 221 closer to each other, and the push blocks 221 drive the clamps 220 to clamp and position the end of the label roll. Then close the baffle 243, push the baffle 243 to reset the feeding rack 21 and the clamps 22, and lock the baffle 243 with the latch 244.

[0045] When another label roll is about to be used up, during the feeding interval, the electromagnet 265 is activated. The electromagnet 265 generates an attractive force to attract the magnetic block 264. The magnetic block 264 drives the guide rod 260 to move. The guide rod 260 stretches the second spring 263. The guide rod 260 pushes the extrusion block 262 outward through the connecting rod 261, so that the extrusion block 262 extrudes the inner wall of the label roll and fixes the label roll.

[0046] Activate the electric push rod 231, which drives the vertical track 230 to descend. The vertical track 230 drives the rubber rod 235 to move down through the slider 234. The rubber rod 235 slides along the arc-shaped area of ​​the vertical track 230, causing the two rubber rods 235 to come closer to each other and squeeze, thereby making the two label rolls stick together. During the descent of the rubber rod 235, the end of the unused label roll is pulled away from the positioning of the clamp 22 and gradually adheres to the other label roll.

[0047] The electric push rod 231 drives the rubber rod 235 to reset, and the electromagnet 265 is turned off, completing the automatic feeding operation.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
