Description

[Technical Field]

[0001] This utility model belongs to the technical field of automated labeling equipment, and in particular relates to a water-absorbing strip circulating feeding mechanism and a decorative label pressing device. [Background Technology]

[0002] Labeling machines are a common type of equipment in the non-standard automation industry. They are devices that use a labeling head to pick up labels and then affix them to products. Currently, conventional labels are peeled off from the release paper and then directly adhered to the adhesive side of the label onto the target product surface using a suction nozzle. This type of label is suitable for product surfaces with a certain surface roughness requirement. However, for glass bottle surfaces, to ensure the label adheres firmly, a special type of label is generally used. This label has a backing paper that needs to be soaked in water before it can be peeled off the backing paper and then applied.

[0003] The prior art patent CN218892816U discloses a water transfer label application pressing device. Before pressing the label, absorbent paper is first used to absorb excess water from the decal label. Then, a silicone pressing head is used to press the label to complete the application. In this device, an unwinding component and a rewinding component are respectively set on both sides of the support plate of the silicone pressing head. The absorbent paper is output from the unwinding component, passes through the space below the silicone pressing head, and is then recycled into the rewinding component. Each time it is pressed, the absorbent paper is rolled up to the rewinding component by a certain length, so that the unabsorbed area is aligned with the silicone pressing head for the next water absorption operation. However, this device has a drawback: the absorbent paper is used up quickly, and a new roll of absorbent paper needs to be replaced manually after it is used up. The high paper replacement frequency seriously affects the continuity of decal label application production and the labeling efficiency.

[0004] Therefore, it is necessary to provide a new absorbent strip circulating feeding mechanism and a decal label pressing device to solve the above-mentioned technical problems. [Utility Model Content]

[0005] One of the main objectives of this utility model is to provide a water-absorbing strip recycling feeding mechanism, which realizes the recycling and reuse of the water-absorbing strip, ensures the continuity of the labeling process, and lays the foundation for improving labeling efficiency.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a water-absorbing strip circulating feeding mechanism, which includes, in sequence along the winding direction of the water-absorbing strip, a first roll feeding and receiving component, a second guide roller group, and a second roll feeding and receiving component, and forms a water-absorbing working area by winding the water-absorbing strip through the section of the second guide roller group; a drying box for drying the water-absorbing strip is provided between the first roll feeding and receiving component and the second guide roller group, and between the second guide roller group and the second roll feeding and receiving component.

[0007] Furthermore, the water-absorbing strip circulating feeding mechanism includes a first guide roller group, which is disposed between the first material roll feeding and receiving assembly and the second guide roller group, and between the second guide roller group and the second material roll feeding and receiving assembly.

An air chamber is formed inside the inner box, and the air chamber is connected to an external heat source. The top of the outer box is provided with a first inlet and outlet, and the bottom is provided with a second inlet and outlet. The shell of the inner box is provided with a plurality of air blowing slots, and the air blowing slots are aligned with the section of the water-absorbing strip located inside the outer box.

[0011] Furthermore, the outer casing is also provided with an openable switch door; when the switch door is opened, the first inlet and the second inlet and the side of the switch door are open, so that the absorbent strip can enter the first inlet and the second inlet and the second inlet and the second inlet from the opening.

[0012] Furthermore, the inner box has a slope, the top of which connects to the first inlet and outlet, and the bottom of which connects to the second inlet and outlet, and the air blowing slot is formed on the slope.

[0013] Furthermore, the drying oven is equipped with a heating plate, and the absorbent strip is attached to the surface of the electric heating plate or passes between two of the electric heating plates.

[0014] Another objective of this utility model is to provide a decal label pressing device, including a support base, an electric cylinder fixed on the support base, a pressing head driven by the electric cylinder to move up and down, and a water-absorbing strip circulation feeding mechanism disposed on the support base as described above; the water-absorbing working area is located below the pressing head.

Detailed Implementation Methods

[0025] Example 1:

[0026] Please refer to Figures 1-4 This embodiment is a decal label pressing device 100, which includes a support base 4, an electric cylinder 2 fixed on the support base 4, a pressing head 1 driven by the electric cylinder 2 to move up and down, and a water-absorbing strip circulating feeding mechanism 3 set on the support base 4.

[0027] The pressing head 1 and the electric cylinder 2 constitute a pressing module. In this embodiment, two pressing modules are provided to press two labels simultaneously. In other embodiments, the pressing modules can be provided in other numbers, such as 1 group, 3 to 10 groups, etc., and the number can be flexibly designed according to requirements. The pressing head 1 is made of silicone.

[0028] The absorbent strip supplied by the absorbent strip circulation feeding mechanism 3 is positioned between the pressing head 1 and the label (i.e., the decorative label with the backing paper removed) when the pressing head 1 presses the label. The absorbent strip circulation feeding mechanism 3 includes a first roll feeding and receiving assembly 31, a second roll feeding and receiving assembly 32, a first guide roller group 33, and a second guide roller group 34. The absorbent strip material 200 of the first roll feeding and receiving assembly 31 (or the second roll feeding and receiving assembly 32) is sequentially wound around the first guide roller group 33, the second guide roller group 34, and the first guide roller group 33 before finally returning to the second roll feeding and receiving assembly 32 (or the first roll feeding and receiving assembly 31). The absorbent strip material 200 wound around the second guide roller group 34 forms a horizontal absorbent working area 201 below the pressing head 1. When the pressing head 1 moves downward to press the label, it simultaneously presses the absorbent working area 201 downward. The pressing head 1 presses the label through the absorbent working area 201, using the absorbent working area 201 to absorb excess moisture from the label, which helps the label to be reliably and effectively pasted onto the object to be labeled (such as glassware).

[0029] The absorbent strip circulation feeding mechanism 3 also includes a movable support plate 35 that slides vertically on the support base 4 and a counterweight assembly 36 that pulls the movable support plate 35 upward. The second guide roller group 34 is mounted on the movable support plate 35. By mounting the second guide roller group 34 on the movable support plate 35, the gravity of the second guide roller group 34 and the movable support plate 35 is used to tension the absorbent strip material 200, keeping the absorbent strip material 200 taut. After the pressing head 1 presses down on the absorbent strip material to complete the labeling pressing, the pressing head 1 will rise to the high position. At this time, the downward pressure on the absorbent strip material 200 is released. Under the action of the counterweight assembly 36, the movable support plate 35 is pulled up to the initial height. The first roll feeding and receiving assembly 31 or the second roll feeding and receiving assembly 32 can then collect the material, straighten the absorbent strip material 200 again, and realize the conveying of the absorbent strip material, allowing the subsequent drying area to be aligned with the pressing head 1 for the next round of labeling pressing and water absorption.

[0030] The first roll feeding and receiving assembly 31, the second roll feeding and receiving assembly 32, and the first guide roller group 33 are mounted on the support base 4.

[0031] To achieve the recycling of the absorbent strip 200, this embodiment optimizes the design of the absorbent strip recycling feeding mechanism 3. Drying chambers 37 for drying the absorbent strip 200 are provided on both the unwinding and rewinding sides of the absorbent strip 200. Specifically, in this embodiment, drying chambers 37 are provided between the first roll feeding / rewinding assembly 31 and the first guide roller group 33, and between the second roll feeding / rewinding assembly 32 and the first guide roller group 33. The absorbent strip 200 passes through the drying chamber 37, is dried, and then rewound at either the end of the first roll feeding / rewinding assembly 31 or the end of the second roll feeding / rewinding assembly 32. After the dried absorbent strip on the first roll feeding / rewinding assembly 31 (or the second roll feeding / rewinding assembly 32) is used up, the second roll feeding / rewinding assembly 32 (or the first roll feeding / rewinding assembly 31) can reverse to output the dried absorbent strip, thus achieving recycling. In other embodiments, the two drying boxes 37 may also be respectively located between the first guide roller group 33 and the second guide roller group 34 on the side of the first roll feeding and receiving assembly 31, and between the first guide roller group 33 and the second guide roller group 34 on the side of the second roll feeding and receiving assembly 32.

[0032] The drying oven 37 includes an outer casing 371 and an inner casing 372 disposed within the outer casing 371. An air chamber (not shown in the figure) is formed inside the inner casing 372, and the air chamber is connected to an external hot air source via a pipe 373. The outer casing 371 has a first inlet / outlet 3711 at the top and a second inlet / outlet 3712 at the bottom. The absorbent strip 200 enters the outer casing 371 through the first inlet / outlet 3711 and exits through the second inlet / outlet 3712, or enters the outer casing 371 through the second inlet / outlet 3712 and exits through the first inlet / outlet 3711. The inner casing 372 has several air-blowing slots 3721 on its shell. These slots are aligned with the section of the absorbent strip 200 located inside the outer casing 371, and hot air from the air chamber is blown out through the air-blowing slots 3721 to dry that section.

[0033] The outer casing 371 is also equipped with an openable door 3713 to facilitate the operation of threading the absorbent strip 200 by the operator. When the door 3713 is opened, the first inlet / outlet 3711 and the second inlet / outlet 3712 are open on the side near the door 3713, so that the absorbent strip 200 can enter the first inlet / outlet 3711 and the second inlet / outlet 3712 through the opening.

[0034] The inner casing 372 has a slope 3722, the top of which connects to the first inlet / outlet 3711 and the bottom of which connects to the second inlet / outlet 3712. The air blowing slot 3721 is formed on the slope 3722. Meanwhile, the absorbent strip 200 is in an inclined state inside the outer casing 371 to reduce the disturbance of hot air to the absorbent strip 200 body.

[0035] In other embodiments, the drying and heating inside the drying chamber 37 can also be electrically heated, with an electric heating plate installed so that the absorbent strip 200 is conveyed in contact with the surface of the heating plate. The electric heating plate can be set in an inclined state. Alternatively, two electric heating plates can be installed, with the absorbent strip 200 passing between the two electric heating plates.

[0036] The working process of the decal label pressing device 100 in this embodiment is as follows: The absorbent strip 200 is first output from the first roll feeding assembly 31, then wound around the first guide roller group 33, the second guide roller group 34, and then wound into the second roll feeding assembly 32. The absorbent strip 200 wound around the second guide roller group 34 forms an absorbent working area 201 below the pressing head 1. After the label object is moved into place, the pressing head 1 in section 2 of the electric cylinder moves downward, bringing the absorbent working area 201 down to contact the label. While the pressing head 1 presses the label, the absorbent working area 201 absorbs the excess water on the label. After the label is pressed and held for a set time, the pressing head 1 moves upward to the high position. The two-roll feeding and receiving component 32 rewinds to a set length, while the first-roll feeding and receiving component 31 unwinds to a set length, aligning the dry area of ​​the absorbent strip 200 with the pressing head 1. Once the next set of labeled objects is in place, the next cycle of labeling and pressing operations begins. When the wet area of ​​the absorbent strip 200 moves into the drying chamber 37, the drying chamber 37 dries the wet area, and after drying, it is rewound to the second-roll feeding and receiving component 32 for recycling. When the absorbent strip in the first-roll feeding and receiving component 31 is completely released, the second-roll feeding and receiving component 32 acts as an unwinding component, releasing the absorbent strip in the reverse direction, while the first-roll feeding and receiving component 31 acts as a rewinding component to recover the strip, achieving continuous use.

[0037] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
