Description

Technical Field

[0001] This utility model relates to the field of multi-layer sticker bonding technology, specifically a multi-layer sticker bonding device. Background Technology

[0002] Multi-layer stickers are labels or stickers made through a multi-layering or composite process. Their key feature is that they can be peeled off in layers and reused repeatedly, often used in scenarios requiring multi-layered information display or interactive functions. The sticker manufacturing process involves a multi-layer sticker lamination technique, where the face paper and backing paper of one layer are peeled off, and then another layer of sticker is adhered underneath the face paper, thus achieving multi-layer sticker lamination.

[0003] According to a Chinese patent publication (CN218315216U), a multi-layer sticker bonding device includes a first unwinding mechanism, a backing paper peeling mechanism, a second unwinding mechanism, a bonding traction roller assembly, and a winding mechanism. A path for unwinding and traction of the second layer of sticker is formed between the second unwinding mechanism and the bonding traction roller assembly. A path for unwinding, peeling, and traction of the first layer of sticker is formed between the first unwinding mechanism, the backing paper peeling mechanism, and the bonding traction roller assembly. A winding path is formed between the bonding traction roller assembly and the winding mechanism for winding the bonded first and second layers of sticker. This device can be used for bonding multi-layer stickers. Except for starting and stopping the device and changing the first and second layers of sticker midway, no manual operation is required, resulting in higher efficiency, a higher yield of finished products, and lower labor costs.

[0004] However, existing devices have the following problems: the distance between the first and second bonding traction rollers is fixed, which limits the bonding of multi-layer stickers of the same thickness, thus reducing the device's applicability. Therefore, a multi-layer sticker bonding device is proposed. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 5This utility model provides a technical solution: a multi-layer sticker bonding device, including a base plate 1;

[0027] A connecting frame 2 is fixedly connected to the top surface of the base plate 1;

[0028] And a fixing plate 3 fixedly connected to the top surface of the connecting frame 2; a guide component 40 and a fitting component 41 are provided on the inner side of the connecting frame 2.

[0029] The guide component 40 is located to the left of the bonding component 41.

[0030] The bonding assembly 41 includes two support plates 414 located inside the connecting frame 2. Mounting brackets 415 are fixedly connected to the adjacent surfaces of the two support plates 414. The two mounting brackets 415 are symmetrically arranged. Pressure rollers 416 are arranged inside the mounting brackets 415. The front and rear end faces of the two pressure rollers 416 are rotatably connected to the inner surfaces of the mounting brackets 415 via bearing seats. A motor 411 is fixedly connected to the top surface of the fixing plate 3. A first through groove is formed on the rear side of the connecting frame 2. Two first T-shaped blocks 413 are arranged on the rear side of the connecting frame 2. The front faces of the two first T-shaped blocks 413 slide through the rear side of the connecting frame 2 and extend into the first through groove. The front faces of the two first T-shaped blocks 413 are fixedly connected to the rear sides of the two support plates 414 respectively. The bottom end face of the motor 411 output rod... The motor 411 output rod has a double-threaded rod 412 fixedly connected to the bottom end of the output rod. The double-threaded rod 412 extends through the top surface of the two first T-blocks 413 and extends to the bottom of the two first T-blocks 413. The bottom end of the double-threaded rod 412 is rotatably connected to the bottom surface of the first through groove through the bearing seat. By using the bonding assembly 41, the motor 411 drives the double-threaded rod 412 to rotate, which drives the two first T-blocks 413 and the support plate 414 fixed thereto to move in opposite directions, thereby precisely adjusting the distance between the two pressure rollers 416. This effectively solves the problem that the pressure roller spacing of the traditional device is fixed and cannot be adapted to stickers of different thicknesses, and significantly expands the applicability of the device.

[0031] Two second T-shaped blocks 417 are provided on the front side of the connecting frame 2. A second through groove is provided on the front side of the connecting frame 2. The rear ends of the two second T-shaped blocks 417 slide through the front side of the connecting frame 2 and extend into the second through groove. The rear ends of the two second T-shaped blocks 417 are fixedly connected to the front sides of the two support plates 414 respectively.

[0032] A sliding rod 418 is provided above the two second T-shaped blocks 417. The bottom end of the sliding rod 418 slides through the top surface of the two second T-shaped blocks 417 and extends to the bottom of the two second T-shaped blocks 417. The top and bottom ends of the sliding rod 418 are fixedly connected to the top and bottom surfaces inside the second through groove, respectively. The sliding rod 418 and the second T-shaped blocks 417 provide stable support and precise guidance for the support plate 414 and the pressure roller 416 on it, effectively preventing displacement or vibration during the pressing process and ensuring the smoothness and reliability of the device operation.

[0033] The two pressure rollers 416 are equipped with heating tubes inside. The heating tubes are integrated inside the pressure rollers 416 (existing technology application). During the pressing process, the heat acts on the sticker adhesive layer, which can soften the glue or activate the heat-sensitive adhesive, greatly improving the bonding firmness and quality between different layers of stickers. It is especially suitable for multi-layer sticker lamination with special adhesive layers.

[0034] Example 2: Based on Example 1, a preferred embodiment of the multi-layer sticker bonding device provided by this utility model is as follows: Figure 1 - Figure 3 As shown: The guide assembly 40 includes a paper feeding tube 401, a first guide roller 402, and a second guide roller 403 located on the left side of the two support plates 414. There are two paper feeding tubes 401, two first guide rollers 402, and two second guide rollers 403 symmetrically arranged. The front and rear end faces of the first guide rollers 402 and the second guide rollers 403 are rotatably connected to the inner side of the connecting frame 2 through bearing seats, respectively. The paper feeding tube 401 is fixedly installed on the inner side of the connecting frame 2. The second guide roller 403 is located to the lower right of the first guide roller 402. The sticker on the surface of the paper feeding tube 401 passes through the top surface of the first guide roller 402 and the bottom surface of the second guide roller 403 in sequence. Through the guide assembly 40, by utilizing the symmetrical arrangement of the paper feeding tube 401, the first guide roller 402, and the second guide roller 403, and equipped with a waste paper tube 404, the sticker is precisely guided along the path by the first guide roller 402 and the second guide roller 403. The peeled backing paper can be automatically rolled up by the waste paper tube 404, reducing manual intervention and improving the automation level and efficiency of the peeling and paper feeding process.

[0035] A waste paper tube 404 is provided at the middle right position of the two paper tubes 401, and the waste paper tube 404 is fixedly installed inside the connecting frame 2.

[0036] In use, the stickers on the paper tube 401 are passed sequentially through the top of the first guide roller 402 and the bottom of the second guide roller 403, and the face paper and back paper of the stickers are peeled off. The peeled back paper is fixed on the waste paper tube 404. When the waste paper tube 404 rotates, it rolls up the peeled back paper. At the same time, when the back paper is pulled, the waste paper tube 404 rotates to facilitate the peeling of the face paper and back paper.

[0037] The upper face paper and the lower sticker are passed through the two pressure rollers 416. The motor 411 is turned on, and the output rod of the motor 411 rotates, which drives the double-headed threaded rod 412 to rotate, so that the two first T-shaped blocks 413 move closer to each other, thereby making the two support plates 414 move closer to each other, and then making the two pressure rollers 416 move closer to each other. The two pressure rollers 416 adhere the upper face paper to the lower sticker, realizing the adhesion of multiple layers of stickers.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
