[0028] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4 A novel continuous laminating device comprises a conveyor belt 1, two groups of double-sided adhesive sticking mechanisms 2 are respectively arranged on both sides of the conveyor belt 1 and along the conveying direction, the four groups of double-sided adhesive sticking mechanisms 2 are respectively used to stick double-sided adhesive on the four sides of the product, a rotating device 3 is arranged on the conveyor belt 1 and located between the front and rear groups of double-sided adhesive sticking mechanisms 2; a tape peeling device 4 is arranged on the conveyor belt 1 and on the rear side of the double-sided adhesive sticking mechanism 2, and a laminating mechanism 5 is arranged on the conveyor belt 1 and on the rear side of the tape peeling device 4.

[0030] The above structure can automatically convey the products to be coated through the conveyor belt 1. The staff only needs to place the products one by one on the conveyor belt 1. When the conveyor belt 1 conveys the products to be coated to two adjacent groups of double-sided adhesive sticking mechanisms 2, the two groups of double-sided adhesive sticking mechanisms 2 simultaneously stick adhesive strips on the left and right sides of the surface of the products. After the sticking is completed, the conveyor belt 1 continues to convey the products. When the products are conveyed to the rotating device 3, the rotating device 3 rotates and reverses the original front-to-back direction to the left-to-right direction. After the reversal is completed, the products continue to be conveyed.

[0031] When it is transported to the two sets of double-sided adhesive gluing mechanisms 2 at the rear, the other two sides of the surface of the product are simultaneously glued with adhesive strips by the two sets of double-sided adhesive gluing mechanisms 2. After the gluing is completed, the product is sent to the adhesive paper peeling device 4 through the conveyor belt 1, and the adhesive paper on the double-sided adhesive strips on the four sides is automatically peeled off by the adhesive paper peeling device 4, and finally automatic lamination is realized under the transportation of the conveyor belt 1.

[0032] like Figure 2As shown, the double-sided adhesive tape sticking mechanism 2 includes a support plate 21 fixedly connected to the outside of the conveyor belt 1, one side of the support plate 21 is fixedly connected to a vertical plate 22, a double-sided adhesive tape feeding assembly 23 is arranged on the support plate 21, a first hydraulic cylinder 24 is fixedly connected to the outside of the vertical plate 22, a cylinder rod of the first hydraulic cylinder 24 is fixedly connected to a connecting plate 25, the connecting plate 25 is an L-shaped structure and is slidably connected to the surface of the first hydraulic cylinder 24, a first electric telescopic rod 26 is fixedly connected to the bottom of the connecting plate 25, a suction plate 27 is fixedly connected to the bottom of the first electric telescopic rod 26, a suction plate 27 is provided with evenly distributed suction holes at the bottom, a first vacuum adsorber 28 is fixedly installed on the inner side of the connecting plate 25, a telescopic suction pipe 29 is connected to the bottom of the first vacuum adsorber 28, and the telescopic suction pipe 29 is connected to the suction plate 27.

[0033] The double-sided adhesive strip feeding assembly 23 includes a double-sided adhesive shaft 231 disposed on the vertical plate 22, a double-sided adhesive strip roll 232 is sleeved on the double-sided adhesive shaft 231, a strip-shaped peeling opening 233 is disposed on the top of the support plate 21 and close to the conveyor belt 1, a double-sided adhesive strip winding device 234 is disposed on the vertical plate 22 and below the support plate 21, and the double-sided adhesive strip roll 232 is connected to the double-sided adhesive strip winding device 234 through the strip-shaped peeling opening 233. In addition, a guide roller 235 is disposed on the vertical plate 22 and close to the surface of the support plate 21 to guide the running direction of the double-sided adhesive strip.

[0034] In the above structure, the conveyor belt 1 stops when conveying the product to be coated to the double-sided adhesive gluing mechanism 2, and the double-sided adhesive winding device 234 works, so that the double-sided adhesive strip roll 232 feeds adhesive toward the conveyor belt 1 and the double-sided adhesive strip is stripped of the bottom adhesive with the help of the strip stripping port 233. At the same time, the first hydraulic cylinder 24 contracts, the first electric telescopic rod 26 extends, and the adsorption plate 27 corresponds to the stripped double-sided adhesive strip, and the double-sided adhesive strip is lowered under the action of the first vacuum absorber 28 to adsorb (the surface adhesive tape of the double-sided adhesive strip is still there at this time), and then the first hydraulic cylinder 24 extends and the first electric telescopic rod 26 contracts to transfer the double-sided adhesive strip to the edge of the product to be coated on the conveyor belt 1. Finally, under the action of the first electric telescopic rod 26, the adsorption plate 27 is pressed down and pasted on the edge of the product, and finally the first vacuum absorber 28 stops working, the adsorption force is canceled, and the first electric telescopic rod 26 is reset to complete the automatic gluing work.

[0035] like Figure 3As shown, the rotating device 3 includes a rotating bracket 31 fixedly mounted on the frame of the conveyor belt 1, a second hydraulic cylinder 32 fixedly connected to the top of the rotating bracket 31 is inserted through the top, a rotating motor 33 is arranged on the inner side of the rotating bracket 31, the top of the rotating motor 33 is fixedly connected to the cylinder rod of the second hydraulic cylinder 32, the output shaft of the rotating motor 33 is fixedly connected to a rotating plate 34, a vacuum suction cup 35 is fixedly connected to the bottom of the rotating plate 34, and second vacuum absorbers 36 are fixedly connected to the two corresponding vacuum suction cups 35 on both sides of the top of the rotating plate 34.

[0036] In this rotating device, after the product that has completed the initial gluing (gluing on the left and right sides) is transported to the bottom of the rotating bracket 31 via the conveyor belt 1, the second hydraulic cylinder 32 extends so that the vacuum suction cup 35 on the rotating plate 34 contacts the unglued part of the product and generates an adsorption force under the action of the second vacuum absorber 36. After the rotating motor 33 rotates and reverses, that is, after the original left and right sides of the product are changed to the front and back sides, the second vacuum absorber 36 cancels the adsorption force and the second hydraulic cylinder 32 resets.

[0037] like Figure 4 As shown, the adhesive tape stripping device 4 includes a fixed plate 41 fixedly connected to the frame of the conveyor belt 1, a single-sided tape roller 42 is rotatably connected to the fixed plate 41, a single-sided tape roller 43 is provided on the single-sided tape roller 42, a single-sided tape winding device 44 is also provided on the fixed plate 41, and a glue pressing assembly 45 is provided between the single-sided tape roller 42 and the single-sided tape winding device 44. The glue pressing assembly 45 includes a fixed frame 451, the fixed frame 451 is fixed to the frame of the conveyor belt 1, a second electric telescopic rod 452 is fixedly connected to the bottom of the fixed frame 451, and a pressing plate 453 is fixedly connected to the bottom of the second electric telescopic rod 452. Guide rollers 46 are provided on the fixed plate 41 and on both the front and rear sides of the fixed frame 451, and guide wheels 47 are provided on the guide rollers 46.

[0038] The adhesive tape stripping device 4 passes the free end of the single-sided film 43 through the guide wheel 47 to the bottom of the pressure plate 453 and then to the single-sided tape winding device 44 through the guide wheel 47. Through the extension and retraction of the second electric telescopic rod 452, the pressure plate 453 sticks the sticky tape on the adhesive tape of the double-sided tape and peels off and reels the adhesive tape on the surface of the double-sided tape under the action of the reeling device. In order to further improve the stripping effect, those skilled in the art can set a single-sided tape guiding and aligning device on the pressure plate 453 according to actual conditions, so that the single-sided tape and the double-sided tape can be better aligned, and the adhesive tape of the double-sided tape can be peeled off conveniently through the adhesive force of the single-sided tape. It should also be noted that the double-sided tape winding device 234 and the single-sided tape winding device 44 are both mechanisms that rotate and reel by driving the rotating shaft with a motor, which is a prior art and will not be described in detail.

[0039] In summary: The advantages of the new continuous coating device of this scheme include:

[0040] 1. High degree of automation: The entire laminating process from product transportation, double-sided tape attachment, rotation reversal, adhesive tape peeling to final lamination is completed automatically, reducing the need for manual operation and improving production efficiency.

[0041] 2. Easy operation: The staff only needs to place the product on the conveyor belt 1, and all subsequent steps are automatically completed by the device, which simplifies the operation process and reduces the difficulty of operation.

[0042] 3. Accurate gluing: Four sets of double-sided adhesive gluing mechanisms 2 are used to respectively stick double-sided adhesive strips on the four side edges of the product, thereby ensuring the accuracy and uniformity of gluing and improving the quality of lamination.

[0044] 5. Automatic peeling of adhesive tape: The adhesive tape peeling device 4 can automatically peel off the adhesive tape on the four-side double-sided adhesive strips, reducing the steps of manual peeling and improving work efficiency.

[0045] 6. Continuous operation: The design of the conveyor belt 1 allows the products to be coated continuously, which is suitable for large-scale production and improves the throughput of the production line.

[0046] 7. Improve product quality: The automated laminating process reduces the impact of human factors, helps maintain the consistency and aesthetics of product lamination, and improves the quality of the final product.

[0047] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
