Description

Technical Field

[0001] The invention relates to the technical field of self-adhesive label production, in particular to a detection and feeding mechanism before self-adhesive labels are coated. Background Art

[0002] Compared to traditional labels, self-adhesive labels have the advantages of eliminating the need for glue, paste, or water, resulting in a pollution-free, time-saving application. They are widely applicable and quick and easy to apply. Self-adhesive labels, also known as self-adhesive label materials, are a composite material made of paper, film, or other specialty materials, with an adhesive coating on the back and a silicone-coated protective paper as the backing. After printing and die-cutting, they become finished labels.

[0003] During the production of self-adhesive labels, it is necessary to unwind the uncoated self-adhesive film roll and then coat it with glue. Currently, after the self-adhesive film roll is unwound, the staff needs to manually replace the self-adhesive film roll, which increases the labor intensity of the staff. In addition, during the uncoiling process of the self-adhesive film roll, the quality of the self-adhesive base tape is mostly visually inspected by the staff. Manual visual inspection can easily lead to inaccurate inspection results and unstable production quality of the self-adhesive film roll. Summary of the Invention

Then, the two third connecting plates above the mounting plate clamp the self-adhesive film roll and move away from the mounting plate to adjust the position of the self-adhesive film roll.

The negative ion wind sprayed outward through the air outlet can blow off the dust on the self-adhesive base tape, thereby increasing the cleanliness of the self-adhesive base tape. This operation method can improve the quality of subsequent self-adhesive base tape gluing and increase the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-12 A detection and loading mechanism for self-adhesive labels before coating is disclosed. The mechanism comprises a mounting plate 1, a rotating rod 15 movably mounted on the mounting plate 1, a fixing mechanism provided on the rotating rod 15, two movable rods 3 movably mounted on the mounting plate 1, and the two movable rods 3 are respectively located above and below the rotating rod 15. A second connecting plate 6 is movably mounted on each side of the two movable rods 3 facing each other, the second connecting plate 6 being provided with a detection mechanism, a first connecting plate 5 movably mounted on each side of the second connecting plate 6, the first connecting plate 5 being provided with an auxiliary mechanism, a first slot 2 extending through the mounting plate 1, and a conveyor belt 22 provided at the end of the first slot 2 on the side of the mounting plate 1 away from the rotating rod 15. The fixing mechanism secures the self-adhesive film roll, the detection mechanism detects the self-adhesive film roll during unwinding, and the auxiliary mechanism, combined with the movable rods 3, enables automatic film roll replacement.

[0036] As a technical optimization solution of the present invention, the end of rotating rod 15 closest to mounting plate 1 is rotatably connected to mounting plate 1. A rotating motor 23 is mounted on the side of mounting plate 1 away from rotating rod 15. The output end of rotating motor 23 faces mounting plate 1 and movably extends through mounting plate 1 and connects to rotating rod 15. By rotating motor 23 driving rotating rod 15 to rotate, automatic unwinding of the self-adhesive film roll can be achieved.

[0037] As a technical optimization solution of the present invention, the fixing mechanism includes an electric extension rod 16 and an abutment plate 17. Multiple abutment plates 17 are evenly arranged along the circumference of the outer side of the rotating rod 15. Multiple electric extension rods 16 are evenly connected to the side of the abutment plate 17 near the rotating rod 15. The mounting ends of the electric extension rods 16 face the rotating rod 15 and are connected to the rotating rod 15. The electric extension rods 16 drive the abutment plates 17 to extend, causing them to abut the inner wall of the self-adhesive film roll retaining ring. This secures the self-adhesive film roll and facilitates the automatic lowering of the self-adhesive film roll retaining ring.

[0038] As a technical optimization solution of the present invention, the mounting plate 1 is provided with a movable chute 7 near the movable rod 3. A fourth electric telescopic rod 35 is embedded and mounted on the end of the movable rod 3 near the mounting plate 1. The mounting end of the fourth electric telescopic rod 35 faces the mounting plate 1. The mounting end of the fourth electric telescopic rod 35 is connected to a movable electric slider 8, which is slidably mounted within the movable chute 7. The sliding of the movable electric slider 8 in the movable chute 7 can drive the movable rod 3 to move on the mounting plate 1. The fourth electric telescopic rod 35 can drive the movable rod 3 to move away from the mounting plate 1 according to usage requirements.

[0039] As a technical optimization solution of the present invention, multiple electric lift rods 4 are evenly embedded and installed on the sides of the two moving rods 3 that face each other. The lifting ends of the electric lift rods 4 are away from the moving rods 3 and connected to the second connecting plate 6. The electric lift rods 4 can drive the second connecting plate 6 to move away from the moving rods 3 according to different usage requirements.

[0040] As a technical optimization solution of the present invention, the detection mechanism includes a movable plate 13 and a pressure sensor 33. The second connecting plate 6 is provided with a fourth slot 30 on the side away from the movable rod 3. The movable plate 13 is slidably mounted inside the fourth slot 30. The movable plate 13 is rotatably mounted with an abutment roller 14 on the side away from the second connecting plate 6. The pressure sensor 33 is mounted on the bottom end of the inner wall of the fourth slot 30. A spring telescopic rod 34 is mounted on the side of the movable plate 13 facing the pressure sensor 33. The end of the spring telescopic rod 34 away from the movable plate 13 abuts against the pressure sensor 33. The vibration generated by the base tape during the unwinding process will be transmitted to the movable plate 13 through the abutment roller 14. The absorption of the vibration value of the movable plate 13 by the spring telescopic rod 34 can achieve a vibration reduction effect during the unwinding process of the self-adhesive base tape, thereby increasing the unwinding stability of the self-adhesive base tape, preventing the self-adhesive base tape from being deflected due to its own vibration during transmission, and increasing the unwinding stability of the self-adhesive base tape.

[0041] The abutment roller 14 rotates during the unwinding process of the self-adhesive base tape, and the movable plate 13 slides inside the second connecting plate 6 and squeezes the pressure sensor 33 through the spring telescopic rod 34. The pressure sensor 33 can measure the squeezing force between the abutment roller 14 and the self-adhesive base tape. When wrinkles occur on the surface of the self-adhesive base tape, the pressure value measured by the pressure sensor 33 is bound to change and exceed the preset pressure value variation range. At this time, combined with the camera 28 shooting the surface of the self-adhesive base tape, the staff can find defects on the self-adhesive base tape more quickly and deal with them, which increases the convenience of using the device.

[0042] As a technical optimization solution of the present invention, stabilizing grooves 31 are formed on the inner walls of both ends of the fourth slot 30. Stabilizing sliders 32 are slidably mounted within the stabilizing grooves 31. The side of the stabilizing slider 32 closest to the movable plate 13 is connected to the movable plate 13. The sliding of the stabilizing slider 32 in the stabilizing grooves 31 can increase the sliding stability of the movable plate 13 within the fourth slot 30.

[0043] As a technical optimization solution of the present invention, the auxiliary mechanism includes a third connecting plate 9. Two second electric telescopic rods 24 are embedded and mounted on the side of the first connecting plate 5 near the second connecting plate 6. The mounting ends of the second electric telescopic rods 24 are connected to the second connecting plate 6. The two first connecting plates 5 on each mobile rod 3 form a group. The two groups of first connecting plates 5 are each movably provided with a third connecting plate 9 on the side facing each other. A third electric telescopic rod 25 is embedded and mounted on the first connecting plate 5. The telescopic end of the third electric telescopic rod 25 is connected to the third connecting plate 9. By clamping the adhesive film retaining ring with the third connecting plate 9 and combining it with the movement of the mobile rod 3, the adhesive film retaining ring can be automatically lowered.

[0044] As a technical optimization solution of the present invention, an air inlet groove 29 is provided inside the third connecting plate 9. An air inlet hole 26 is provided on the side of the third connecting plate 9 away from the second connecting plate 6. The air inlet hole 26 is connected to the air inlet groove 29. The air inlet groove 29 is evenly penetrated by a plurality of air outlet holes 27 on the inner wall of the side away from the first connecting plate 5. When the negative ion blower connected to the air inlet hole 26 is started, the negative ion wind enters the interior of the air inlet groove 29 and is then ejected through the air outlet holes 27. The negative ion wind ejected outward through the air outlet holes 27 can blow off the dust on the self-adhesive base tape, thereby increasing the cleanliness of the self-adhesive base tape. This operation method can improve the quality of subsequent self-adhesive base tape gluing and increase the convenience of use of the device.

[0045] As a technical optimization solution of the present invention, the third connecting plate 9 above the rotating rod 15 is evenly embedded with multiple cameras 28 on the side away from the first connecting plate 5, and the third connecting plate 9 below the rotating rod 15 is provided with a second slot 10 on the side away from the first connecting plate 5, and a lifting plate 11 is slidably installed inside the second slot 10, and a first electric telescopic rod 18 is installed at the bottom end of the inner wall of the second slot 10, and the telescopic end of the first electric telescopic rod 18 is connected to the lifting plate 11, and a third slot 19 is provided on the side of the lifting plate 11 away from the first electric telescopic rod 18, and a rotating plate 20 is movably installed inside the third slot 19, and a rotating motor 21 is embedded and installed at both ends of the rotating plate 20, and the mounting end of the rotating motor 21 is connected to the inner wall of the third slot 19, and a plurality of rollers 12 are evenly and rotatably installed on the side of the rotating plate 20 away from the first electric telescopic rod 18. The camera 28 can capture the base tape during the unwinding process of the self-adhesive film, and combined with the detection of the base tape by the pressure sensor 33, the combined detection method of the two can increase the accuracy of the device function detection results. At the same time, the camera 28 can provide accurate operation trajectory support for the device when the device operates different functions. The first electric telescopic rod 18 drives the lifting plate 11 to rise and fall, so that the roller 12 abuts against the self-adhesive film to provide mobile support for the self-adhesive film. When the position of the self-adhesive film needs to be fixed, the position of the lifting plate 11 is adjusted so that the roller 12 does not abut against the self-adhesive film. At this time, the self-adhesive film can be stably placed on the third connecting plate 9. The rotating motor 21 drives the rotating plate 20 to rotate, and the abutment angle between the roller 12 and the self-adhesive film can be adjusted, so that the movement of the self-adhesive film on the roller 12 is smoother.

[0046] When the present invention is in use, the electrical equipment used in the device is powered by an external power supply through a wire. The device controls the electrical equipment in the device by setting up a control system. The pressure sensor 33 and the conveyor belt 22 used in the device are both existing mature technologies, so they will not be elaborated on in detail. The top of the conveyor belt 22 is used at a level higher than the level of the inner wall of the bottom end of the first slot 2. When the device is in use, the air inlet 26 is connected to a negative ion fan preset outside the device through a conduit. The connection method between the conduit and the negative ion fan and the air inlet 26 is the same as the negative ion fan, which are all existing mature technologies. Therefore, they will not be elaborated on in detail. The reserved length of the conduit is sufficient for the third connecting plate 9 to perform multiple functional operations. The outer sides of the third connecting plate 9, the roller 12 and the abutting roller 14 are all provided with a rubber coating.

[0047] When the device is in use, the uncoated self-adhesive film roll is sleeved on the outer side of the rotating rod 15, and the abutment plate 17 is extended by the electric extension rod 16, so that the abutment plate 17 abuts against the inner wall of the self-adhesive film roll fixing ring to complete the fixation of the self-adhesive film roll. Then the staff pulls out the head of the base tape in the self-adhesive film roll in the direction of pulling out. Figure 1 The direction from the rotating rod 15 to the first slot 2 is used as the standard. The self-adhesive film roll can be unwound by rotating the rotating rod 15 driven by the rotating motor 23. Then the staff will wind the head of the self-adhesive film roll onto the self-adhesive coating machine. The self-adhesive coating machine is an existing mature technology, so it will not be elaborated on in detail.

[0048] After the adhesive film base is installed, the electric slider 8 slides in the moving slide groove 7, causing the moving rod 3 to move close to the first slot 2 on the installation plate 1. After the moving rod 3 moves to the preset use position, the electric lifting rod 4 drives the second connecting plate 6 to extend, causing the two second connecting plates 6 to move toward the adhesive film base until the two abutting rollers 14 respectively abut the top and bottom of the adhesive film base. At this time, the side of the third connecting plate 9 away from the first connecting plate 5 does not contact the adhesive film base. The camera 28 can take pictures of the surface of the adhesive film base and transmit them to the background control system. The roller 14 rotates during the unwinding process of the self-adhesive base tape, and the movable plate 13 slides inside the second connecting plate 6 and squeezes the pressure sensor 33 through the spring telescopic rod 34. The pressure sensor 33 can measure the squeezing force between the abutting roller 14 and the self-adhesive base tape. When wrinkles occur on the surface of the self-adhesive base tape, the pressure value measured by the pressure sensor 33 is bound to change and exceed the preset pressure value variation range. At this time, combined with the camera 28 shooting the surface of the self-adhesive base tape, the staff can find defects on the self-adhesive base tape more quickly and deal with them, which increases the convenience of using the device.

[0049] During the unwinding process of the self-adhesive base tape, the vibration generated by the base tape during the unwinding process is transmitted to the movable plate 13 through the abutment roller 14 through the abutment on the surface of the base tape and the sliding of the movable plate 13 inside the fourth slot 30. The vibration value of the movable plate 13 is absorbed by the spring telescopic rod 34, which can achieve a vibration reduction effect during the unwinding process of the self-adhesive base tape, thereby increasing the unwinding stability of the self-adhesive base tape, preventing the self-adhesive base tape from being transmitted due to its own vibration during transmission, and increasing the unwinding stability of the self-adhesive base tape.

[0050] During the unwinding process of the self-adhesive film roll, the negative ion blower connected to the air inlet 26 is started, and the negative ion wind enters the interior of the air inlet groove 29 and is then ejected through the air outlet 27. The negative ion wind is ejected outward through the air outlet 27, which can blow off the dust on the self-adhesive base tape and increase the cleanliness of the self-adhesive base tape. This operation method can improve the quality of subsequent self-adhesive base tape gluing and increase the convenience of use of the device.

[0051] After the self-adhesive film roll on the rotating rod 15 is unwound, it is necessary to change the self-adhesive film roll on the rotating rod 15. At this time, the device operates according to the following steps. First, the two moving rods 3 move again to Figure 1 In the use state shown, the second connecting plate 6 above the rotating rod 15 then moves toward the rotating rod 15, and the second connecting plate 6 moves to the preset use position. The second electric telescopic rod 24 drives the first connecting plate 5 to move away from the second connecting plate 6 and move to the preset use position. Then, the third connecting plate 9 is driven by the third electric telescopic rod 25 to move away from the first connecting plate 5 until the bottom of the third connecting plate 9 moves to a position at a horizontal height below the central axis of the rotating rod 15. At this time, the second electric telescopic rod 24 drives the first connecting plate 5 to retract, so that the third connecting plate 9 abuts against the outer wall of the adhesive film roll fixing ring. Then, the abutment plate 17 moves toward the rotating rod 15, no longer supporting and fixing the self-adhesive film roll fixing ring. The fourth electric telescopic rod 35 drives the moving rod 3 to move away from the mounting plate 1. During the movement of the moving rod 3, the third connecting plate 9 clamps the self-adhesive film roll fixing ring remaining on the rotating rod 15. After the moving rod 3 moves to the preset position, the two first connecting plates 5 move away from each other to lower the clamped self-adhesive film roll fixing ring, completing the automatic removal of the self-adhesive film roll fixing ring remaining on the rotating rod 15. Then, the moving rod 3, the first connecting plate 5, and the third connecting plate 9 perform a reset movement.

[0052] Then the two moving rods 3 are moved to the preset use position at the first slot 2, and the third connecting plate 9 under the rotating rod 15 is moved to the preset use position by the second electric telescopic rod 24 and the third electric telescopic rod 25, and the first electric telescopic rod 18 drives the lifting plate 11 to rise and fall, so that the lifting plate 11 moves out of the second slot 10. Then, according to the size of the self-adhesive film roll processed by the device, the rotating motor 21 is controlled to drive the rotating plate 20 to rotate, so that the rotating plate 20 rotates to a preset use angle. At the same time, the uncoated self-adhesive film roll is conveyed on the conveyor belt 22, and the length direction of the self-adhesive film roll fixing ring is horizontal to the length direction of the rotating rod 15. When the self-adhesive film roll passes through the first slot 2, the outer side of the self-adhesive film roll abuts the top of the roller 12. When the self-adhesive film roll leaves the conveyor belt 22, the self-adhesive film roll is located on the top of the two third connecting plates 9 below the mounting plate 1, and then the two above the mounting plate 1 After the first lever 18 is lifted up, the lever 18 moves back to its original position, and the second lever 18 moves back to its original position, so that the lever 18 can move up and down, thereby making the lift easier to operate.

[0053] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
