Its base material is various, such as copper plate paper, smooth surface, good printing suitability, commonly used for general commodity label;There is PET film, which has good transparency, weather resistance and tensile resistance, suitable for waterproof, moisture-proof and durable product label;In addition, PP film is also one of the common base materials, which has good flexibility.
[0003] At present, a part of self -adhesive label must carry out quality detection work on the front and back of the label after completing production and manufacturing due to specific use demand, quality standard or application scene factor. For example, those used for high-grade commodity packaging self -adhesive label, not only the printing effect of the front is guaranteed clear, pattern complete and color accurate, the glue smearing uniformity and whether there is defect on the back also will affect the final paste effect and overall quality;For example, the self -adhesive label applied on the surface of transparent object, because it can be seen from both sides, so the appearance of both sides must be ensured to be defect-free.
[0004] In the detection process, these self -adhesive labels need to be moved into the detection device twice, or cooperate with two detection devices, and also need to carry out range in the middle, which undoubtedly increases the process steps and time cost in the whole production process, and the devices also need reasonable layout and connection arrangement to ensure that the label can smoothly flow between them to complete the detection, which greatly increases the complexity of production layout, occupies more space, and is difficult to apply in small factories.
[0005] Therefore, in order to solve the above technical problems, the quality detection device for self -adhesive label is provided. Utility model content
[0006] In view of the defects in the prior art, the purpose of the utility model is to provide a quality detection device for self -adhesive label.
[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a quality inspection device for self-adhesive labels, comprising two symmetrical half-shells, each of which is equipped with a detection mechanism, and both sides of the half-shells are provided with a through slot for the self-adhesive label to pass through, and the back of the half-shells is equipped with a lifting and fixing assembly. When in use, the two half-shells are lifted and lowered, and after being lifted to the appropriate position, they are fitted together and locked to form a complete shell, so as to cover the upper and lower sides of the self-adhesive label while it is driven by the winding device, so that the self-adhesive label passes through the complete shell and moves in the through slot, and the quality of its upper and lower surfaces is inspected by the detection mechanisms on the upper and lower sides.

[0011] Preferably, an electric telescopic rod is fixedly connected to the interior of the half shell at a position next to the detection mechanism, and a small laser marking machine is installed at the telescopic position of the electric telescopic rod. The top of the half shell is installed with a control device that drives the electric telescopic rod to move the small laser marking machine downward to mark the self-adhesive label at that end when the detection mechanism detects that a certain section of the self-adhesive label has a quality defect.

[0027] like Figure 1-4 As shown, the utility model provides a quality inspection device for self-adhesive labels, comprising two symmetrical half shells 1, each of which is provided with an inspection mechanism 4, both sides of the half shells 1 are provided with a through slot 3 for the self-adhesive label to pass through, and a lifting and fixing component 2 is installed on the back of the half shells 1.
[0028] When in use, the device is moved to a suitable position, that is, the position where the half shell 1 is aligned with the self-adhesive label in the process of movement (the self-adhesive label moves horizontally). In the initial state, the upper half shell 1 is above the self-adhesive label, and the lower half shell 1 is below the self-adhesive label. Then, the two half shells 1 are lifted and lowered by the lifting and fixing component 2. After being lifted and lowered to the appropriate position, they fit together and are locked to form a complete shell, so as to cover the upper and lower sides of the self-adhesive label while it is driven by the winding device, so that the self-adhesive label passes through the complete shell and moves in the through groove 3. The quality of its upper and lower surfaces is detected by the detection mechanisms 4 on the upper and lower sides. In this way, the double-sided detection of the self-adhesive label can be completed directly during its movement, thereby reducing the process steps and time of producing the self-adhesive label. At the same time, there is no need to move the self-adhesive label additionally, thereby reducing space occupancy and being well suitable for small factories.
[0029] It should be noted that the inspection mechanism 4 includes but is not limited to appearance inspection equipment, printing quality inspection equipment, etc.
[0030] Moreover, an electric telescopic rod 6 is fixedly connected to the part next to the detection mechanism 4 inside the half shell 1, and a small laser marking machine 7 is installed at the telescopic part of the electric telescopic rod 6. The top of the half shell 1 is installed with a control device 8. When the detection mechanism 4 detects that a certain section of the self-adhesive label has quality defects, the electric telescopic rod 6 drives the small laser marking machine 7 to move downward to mark the self-adhesive label at that end, thereby marking the end of the self-adhesive label with quality defects without manual operation. The control device 8 includes a power supply, a microprocessor and an actuator.
[0031] The power supply is used to power other components on the control device 8. When the detection mechanism 4 detects that the self-adhesive label has quality defects, it will send a signal to the microprocessor. The microprocessor is used to receive the signal sent by the detection mechanism 4 and send a signal to the actuator to drive the electric telescopic rod 6 to rise and fall, and to control the switch of the small laser marking machine 7. That is, the electric telescopic rod 6 is first controlled to move downward, and the small laser marking machine 7 is turned on at the same time. The electric telescopic rod 6 drives the small laser marking machine 7 to move to the position of the self-adhesive label to mark the self-adhesive label with quality defects (when the small laser marking machine 7 moves downward, the self-adhesive label with quality defects is moved just below the small laser marking machine 7). After marking, the electric telescopic rod 6 retracts and returns to its initial position, and the small laser marking machine is turned off, waiting for the next signal to be sent and repeating the above operation.
[0032] The present invention also provides a specific structure of the lifting and fixing assembly 2: the lifting and fixing assembly 2 includes a horizontal plate 201 fixed to the back of the half-shell 1, and a plurality of through-holes 202 are formed in the interior of the horizontal plate 201. Screws 203 are inserted into each of the through-holes 202, and the bottom ends of the screws 203 are fixedly connected to bases 204. The outer walls of the screws 203 are located on the upper and lower sides of the horizontal plate 201 and are threadedly connected to nuts 205. Guide rails 206 are fixedly connected to both sides of the top of the base 204, and the two sides of the horizontal plate 201 are slidably connected to the guide rails 206 via sliders 207.
[0033] That is, the half shell 1 is pulled up and down, and the half shell 1 drives the horizontal plate 201 to move up and down, and the horizontal plate 201 drives the slider 207 to move up and down. The slider 207 slides up and down along the guide rail 206 to maintain the linear movement of the horizontal plate 201, and also moves up and down along the screw 203 through the through hole 202 on the horizontal plate 201. When locking, rotate the nuts 205 on both sides of the horizontal plate 201 so that the nuts 205 move to the middle part and press against the upper and lower sides of the screw 203, thereby fixing the height of the horizontal plate 201, and also fixing the height of the half shell 1.
[0034] Furthermore, the other end of the half shell 1 connected to the horizontal plate 201 is fixedly connected with a magnet 9 that attracts each other, that is, when the two half shells 1 are fitted together, the magnets 9 thereon are also attracted to each other and fitted together, thereby avoiding the existence of a gap at the other end where the two half shells 1 are connected, improving the integrity of the structure, and thus reducing vibration (the two half shells 1 that are not tightly fitted are more likely to vibrate due to the surrounding environment). Universal wheels 5 are installed around the bottom end of the base 204 to facilitate the staff to move and operate the device.
[0035] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form; any person skilled in the art can smoothly implement the present application according to the drawings shown in the specification and the above description; however, any person skilled in the art can make slight changes, modifications and equivalent changes of the present application within the scope of the technical scheme of the present application, and the equivalent embodiments of the present application are still within the protection scope of the technical scheme of the present application.
