Description

Technical Field

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

[0002] Packaging labeling equipment is a device that uses automated mechanical structures and electronic control systems to precisely affix labels (such as self-adhesive labels, paper labels, and plastic labels) to the surface of packaging. Currently, the most commonly used labeling technologies in industry include self-adhesive labeling, hot melt adhesive labeling, and paste labeling. Due to the complexity of hot melt adhesive labeling and paste labeling, they have been gradually replaced by self-adhesive labeling. When using self-adhesive labeling, it is only necessary to peel the backing paper from the adhesive printing paper to stick the printing paper onto the packaging box.

[0003] However, in the actual labeling process, manual peeling of the backing paper is often used, which is time-consuming and labor-intensive and not suitable for continuous processing. If mechanical equipment is used for automated labeling, in order to solve the problem of synchronizing continuous labeling and peeling, complex high-precision equipment is required. Therefore, professional personnel are required to operate the equipment during use and maintenance, which is not conducive to inspection and maintenance and significantly increases the maintenance cost of the device. To address this, we propose a packaging labeling device that can facilitate continuous labeling and reduce maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the problem in the background technology that high-precision equipment has a complex structure and is inconvenient to inspect and maintain, and to propose a packaging labeling device that can conveniently and continuously apply labels and reduce maintenance costs.

[0005] The technical solution of this utility model: A packaging labeling device, including a frame, the frame being composed of a base plate and a top plate, and further comprising: A pressing assembly is fixedly installed between a bottom plate and a top plate. The pressing assembly is equipped with a cylinder, and a pressing plate is fixedly installed at the output end of the cylinder. The pressing plate is used to push the label paper and stick it to the packaging box with adhesive. The roller assembly consists of a label paper take-up roller, a waste paper take-up roller, and a bottom paper take-up roller rotatably mounted on the frame. The roller assembly is used to peel off the adhesive printing portion and adhesive protective paper from the label paper. Two guide rollers are rotatably mounted between the bottom plate and the top plate. The guide rollers are used to guide the label paper and keep it parallel to the labeling surface of the packaging box.

[0006] Optionally, the pressing assembly includes a first frame plate and a second frame plate, both of which are fixedly installed between the bottom plate and the top plate. The cylinder is fixedly installed on the first frame plate, and the pressing plate is movably installed on the second frame plate via several limiting rods.

[0007] Optionally, a first motor and a second motor are fixedly installed on the upper surface of the top plate. The output end of the first motor is engaged with one end of the roller shaft of the waste paper take-up roller, and the output end of the second motor is engaged with one end of the roller shaft of the label paper take-up roller.

[0008] Optionally, two support mounting openings are cut into the base plate, and roller support seats are inserted through the support mounting openings. Positioning bolts are movably inserted through the roller support seats, and the threaded ends of the positioning bolts are threadedly connected to the base plate. The bottom ends of the roller shafts of the label paper take-up roller and the waste paper take-up roller are rotatably connected to the matching roller support seats.

[0009] Optionally, a roller pressure plate is fixedly installed on one side of the top plate, and a roller support plate is fixedly installed on one side of the bottom plate and below the roller pressure plate.

Detailed Implementation

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0015] like Figures 1-3 As shown, the present invention proposes a packaging labeling device, comprising a frame consisting of a base plate 1 and a top plate 4. A pressing assembly 7 is mounted on the frame. A cylinder 72 and a pressing plate 74 on the pressing assembly 7 are installed between the base plate 1 and the top plate 4. One end of the pressing plate 74 is fixedly connected to the output end of the cylinder 72, ensuring that the cylinder 72 can drive the pressing plate 74 to move horizontally, facilitating the pressing plate 74 to press the adhesive printing portion of the label paper, thus fixing the label adhesive to the outer surface of the packaging box. A roller assembly is rotatably mounted on the frame, consisting of a label paper winding roller 2, a waste paper winding roller 3, and a bottom paper winding roller 6. The label paper winding roller 2 is used to store the label paper that has been completely wound (without the bottom paper 30 and adhesive paper 20 peeled off). The waste paper winding roller 3 is used to pull the label paper and remove the printed portion. The waste paper 10 is wound up for easy collection. The bottom paper winding roller 6 is used to pull and wind up the bottom paper 30, making it easy to peel the bottom paper 30 off the adhesive surface of the adhesive paper 20. When the label paper winding roller 2, the waste paper winding roller 3, and the bottom paper winding roller 6 rotate synchronously at the same speed, the continuous feeding of the label paper and the synchronous peeling of the bottom paper 30 can be achieved. Two guide rollers 5 are installed together between the bottom plate 1 and the top plate 4. The adhesive paper 20 after the glass bottom paper 30 is overlapped on the two guide rollers 5 to ensure that the adhesive surface of the adhesive paper 20 can be close to the outer surface of the packaging box. The adhesive paper 20 has several broken grooves that form a closed area. The inner part of the broken grooves is the printing part. When the pressing component 7 pushes the printing part towards the packaging box, the printing part can be peeled off from the adhesive paper 20, making it easy to stick it on the packaging box.

[0016] like Figures 1-3As shown, in order to facilitate the pressing and adhesive application of the printed portion on the adhesive paper 20 onto the packaging box, a first frame plate 71 and a second frame plate 73 are fixedly installed between the bottom plate 1 and the top plate 4. A cylinder 72 is fixedly installed on the first frame plate 71, and a pressing plate 74 is movably installed on the second frame plate 73 via several limiting rods. The limiting rods limit the pressing plate 74 vertically. When the cylinder 72 drives the pressing plate 74 to move laterally, it can improve the stability of the pressing plate 74 during lateral movement. When the pressing plate 74 moves to one side of the packaging box, it can be precisely aligned with the printed portion on the adhesive paper 20, making it convenient to press and adhesive the printed portion onto the packaging box.

[0017] Furthermore, a first motor 41 and a second motor 42 are fixedly installed on the upper surface of the top plate 4. The output end of the first motor 41 is engaged with the top end of the roller shaft of the waste paper winding roller 3 to ensure that the first motor 41 can drive the waste paper winding roller 3 to rotate, facilitating the winding and collection of waste paper 10. The output end of the second motor 42 is engaged with the top end of the roller shaft of the label paper winding roller 2 to ensure that the second motor 42 can drive the label paper winding roller 2 to rotate, facilitating the unloading of label paper from the label paper winding roller 2. The speed of the first motor 41 and the second motor 42 is controlled by an external control box to ensure that the first motor 41 and the second motor 42 maintain the same speed. During the process of the waste paper winding roller 3 winding the waste paper 10 and the label paper winding roller 2 unloading the label paper, the adhesive paper 20 can be kept taut, preventing the part of the adhesive paper 20 overlapping the two guide rollers 5 from becoming loose.

[0018] Secondly, a roller pressure plate 44 is fixedly installed on one side of the top plate 4, and a roller support plate 11 is fixedly installed on one side of the bottom plate 1 and below the roller pressure plate 44. The waste paper winding roller 3 is rotatably installed between the roller support plate 11 and the roller pressure plate 44. A third motor 43 is fixedly installed on the upper surface of the roller pressure plate 44. The output end of the third motor 43 is engaged with the top of the roller shaft of the bottom paper winding roller 6 to ensure that the third motor 43 can drive the waste paper winding roller 3 to rotate, so as to peel off the bottom paper 30 covering the adhesive paper 20 and wind it up. The speed of the third motor 43 is controlled by an external control box to keep its speed synchronized with the speed of the first motor 41 and the second motor 42, so as to ensure that the bottom paper 30 can be kept taut and wound up on the bottom paper winding roller 6.

[0019] like Figures 1-4As shown, to facilitate the assembly and disassembly of the label paper take-up roller 2 and the waste paper take-up roller 3, two support seat assembly ports 13 are chiseled in the base plate 1. The roller shaft support seat 12 is inserted into the support seat assembly port 13 from below the base plate 1. After the bottom ends of the roller shafts of the label paper take-up roller 2 and the waste paper take-up roller 3 are rotatably connected with the matching roller shaft support seat 12, the roller shaft support seat 12 is fixedly installed on the base plate 1 using the positioning bolt 121, and the two roller bodies can be installed. After the roller shaft support seat 12 is removed from the base plate 1, the restriction on the bottom ends of the roller shafts of the label paper take-up roller 2 and the waste paper take-up roller 3 can be released, making it convenient to remove the label paper take-up roller 2 and the waste paper take-up roller 3 from the frame.

[0020] Furthermore, to facilitate the disassembly and assembly of the bottom paper take-up roller 6, the top end of the roller shaft of the bottom paper take-up roller 6 is inserted into the bearing seat on the lower surface of the roller shaft pressure plate 44, and the bottom end of the roller shaft of the bottom paper take-up roller 6 is inserted into the bearing seat on the upper surface of the roller shaft support plate 11. Then, the positioning screw 111 is used to fix the roller shaft support plate 11 on the base plate 1, and the bottom paper take-up roller 6 can be installed. When the bottom paper 30 wound on the bottom paper take-up roller 6 is saturated, the positioning screw 111 is removed and the roller shaft support plate 11 is removed from the base plate 1, which releases the restriction on the bottom end of the bottom paper take-up roller 6, making it easy to remove.

[0021] In this embodiment, the second motor 42 first drives the label paper take-up roller 2 to rotate, and then unloads the label paper wound on the label paper take-up roller 2. During this process, the first motor 41 drives the waste paper take-up roller 3 to rotate, and then pulls the label paper to ensure that the adhesive paper 20 can be kept taut and overlapped on the two guide rollers 5. The two guide rollers 5 limit the printing part of the adhesive paper 20 to ensure that the printing part can be kept horizontal and placed on one side of the packaging box. At the same time, the third motor 43 drives the bottom paper take-up roller 6 to rotate, and then winds the bottom paper 30 to facilitate peeling the bottom paper 30 from the adhesive surface of the adhesive paper 20. Through external control The box-making control system synchronizes the speeds of the first motor 41, the second motor 42, and the third motor 43, enabling continuous supply of adhesive paper 20 and simultaneous peeling of the base paper 30. This facilitates operation and improves labeling efficiency. The adhesive paper 20 has pre-drilled grooves forming closed sections, with the inner part of these grooves being the printing area. When the pressing component 7 pushes the printed area towards the packaging box, it can be peeled off the adhesive paper 20, facilitating its adhesive fixation onto the packaging box. This device has a simple structure, high labeling efficiency, and compared to high-precision automated equipment, it is easier to operate and maintain, effectively reducing maintenance costs.

[0022] The above specific embodiments are merely several optional embodiments of this utility model.
