The lower surface of the connection housing 613 is fixedly connected with the rectangular base 617. Through the settings of the curved guide groove plate 601, the feeding motor 602, the motor support column 603, the turntable 604, the micro push rod 605, the L-shaped push plate 606, the spring 607, the anti-slip push block 608, the first guide straight plate 609, the limit post 610, the adjustment threaded post 611, the second guide straight plate 612, the connection housing 613, the width adjustment knob 614, the conveyor belt 615, the power motor 616 and the rectangular base 617, when in use, rotate the width adjustment knob 614 to adjust the gap between the first guide straight plate 609 and the second guide straight plate 612 to an appropriate width size. Then place the product above the conveyor belt 615 and start the power motor 616 to drive the product into the curved guide groove plate 601. At this time, start the feeding motor 602, and the feeding motor 602 drives the micro push rod 605, the L-shaped push plate 606, the spring 607 and the anti-slip push block 608 to the position of the product. The micro push rod 605 pushes the L-shaped push plate 606 to make the anti-slip push block 608 firmly clamp the product and transfer it above the limit seat 513. With such a setting, compared with traditional machinery, this device has the effect of clamping the feeding product, improves the stability of the product during the feeding process, avoids displacement, and ensures the accuracy and reliability of feeding.Improve the accuracy and efficiency of the labeling operation.
[0036] Furthermore, the shape of the curved guide groove plate 601 is a quarter circle. An arc is provided at the discharge port of the curved guide groove plate 601, and its size is in line with that of the fixing cap. Through the setting of the curved guide groove plate 601, during use, the quarter-circle shape can provide guidance for the material along a specific trajectory, enabling the material to move smoothly along the predetermined path, reducing deviation and chaos, ensuring the accuracy and stability of feeding. The arc design at the discharge port that matches the size of the limit seat 513 allows the material to accurately enter the limit seat 513, improving the accuracy of connection with other components and reducing the possibility of material spillage or misalignment, which helps to enhance the coherence and reliability of the entire production process.
[0037] Furthermore, five notches are provided on the upper surface of the turntable 604. The micro push rod 605, L-shaped push plate 606, spring 607, and anti-slip push block 608 are symmetrically arranged at its notches with the central axis of the turntable 604. Through the setting of the micro push rod 605, L-shaped push plate 606, spring 607, and anti-slip push block 608, during use, the micro push rod 605 can precisely control the length and force of extension and retraction, and can accurately push the L-shaped push plate 606 according to the size, shape, and position of the product, achieving accurate clamping of products of different specifications, improving the flexibility and adaptability of the operation. The L-shaped push plate 606 and the anti-slip push block 608 cooperate with each other to clamp the product from different angles and directions, increasing the contact area and friction with the product. The material of the anti-slip push block 608 usually has good anti-slip performance, which can effectively prevent the product from sliding or falling off during clamping and transfer, making the clamping more stable and reliable.
[0038] Furthermore, two groups of springs 607 are provided on one side surface of the L-shaped push plate 606, and multiple groups of anti-slip patterns are provided on one side surface of the anti-slip push block 608.

Compared with a single group of springs, they can absorb and disperse the impact force generated during clamping to a greater extent, and more effectively protect the product from being pinched or damaged. This is especially significant for protecting precision and fragile products. The multiple groups of anti-slip patterns can significantly increase the friction between the anti-slip push block 608 and the product surface, making it more difficult for the product to slide when being clamped. Even under high-speed operation or vibration, the product can be firmly fixed in the clamping position, improving the reliability of the entire feeding process.
[0039] Further, two sets of limit posts 610 are symmetrically arranged at equal intervals on the left and right sides of the adjusting threaded post 611 in parallel. The first guiding straight plate 609 is slidably connected to the limit posts 610 through the adjusting threaded post 611. With the arrangement of the limit posts 610 and the adjusting threaded post 611, during use, the two sets of limit posts 610 are symmetrically arranged at equal intervals in parallel, which can provide an accurate positioning reference for the sliding of the first guiding straight plate 609, ensure its sliding along the specified path, avoid deviation or shaking, and guarantee the accuracy and stability of related operations. The position of the first guiding straight plate 609 can be accurately controlled by rotating the adjusting threaded post 611. Operators can finely adjust the position of the first guiding straight plate 609 by slightly adjusting the rotation angle of the threaded post according to specific working requirements, so as to meet the requirements for position accuracy of different products or processes.

[0045] A method for using a PETG hot melt adhesive label labeling device, adopting a PETG hot melt adhesive label labeling device in Embodiment 1, further comprising the following steps:
[0046] Step 1: According to the size of the product to be labeled, rotate the width adjusting knob 614. By adjusting the cooperation between the threaded column 611 and the limit post 610, adjust the gap between the first guiding straight plate 609 and the second guiding straight plate 612 to an appropriate width size to adapt to the lateral size of the product. At the same time, rotate the height clearance adjusting knob 510. Through the cooperation of the first rotating layer 509, the second rotating layer 511, and the third rotating layer 515, adjust the height between the rotating layers to adapt to the height size of the product, ensuring that the equipment can accurately operate on the product;
[0047] Step 2: Place the product above the conveyor belt 615, start the power motor 616, and the power motor 616 drives the conveyor belt 615 to run, so as to convey the product into the curved guide groove plate 601. Under the guiding action of the curved guide groove plate 601, the product moves smoothly along the predetermined path, reducing deviation and chaos, and ensuring the accuracy and stability of feeding;
[0048] Step 3: When the product reaches the designated position, start the feeding motor 602, the feeding motor 602 drives the turntable 604 to rotate, and the micro push rod 605 on the turntable 604 moves accordingly until the product reaches above the limit seat 513, and then start the electric push rod 516 to realize the clamping of the product by the fixed cap 517 and the limit seat 513;
[0049] Step 4: Start the sticker motor 505, the sticker motor 505 drives the sticker roller 506 to rotate, so that the label strip 3 is released from the label reel 2. Due to the engagement connection between the guide groove 503 and the engagement block 504, and the cooperation between the engagement holes on the inner side of the guide groove 503 and the engagement protrusions on the outer side of the engagement block 504, the distance between the sticker roller 506 and the product can be adjusted by pushing the sticker motor 505, so that the label can be accurately attached to products of different widths and sizes.
[0050] Working principle: For this PETG hot-melt adhesive label pasting device and method, through the setting of the feeding size adjustment mechanism 6, rotate the width adjustment knob 614 to adjust the gap between the first guiding straight plate 609 and the second guiding straight plate 612 to an appropriate width. Then place the product above the conveyor belt 615 and start the power motor 616 to drive the product into the curved guiding groove plate 601. At this time, start the feeding motor 602. The feeding motor 602 drives the micro-push rod 605, L-shaped push plate 606, spring 607 and anti-slip push block 608 to the position of the product. The micro-push rod 605 pushes the L-shaped push plate 606 so that the anti-slip push block 608 firmly clamps the product and transfers it above the limit seat 513. With such a setting, compared with traditional machinery, this device clamps the fed product, improves the stability of the product during the feeding process, avoids displacement, ensures the accuracy and reliability of feeding, and improves the precision and efficiency of the labeling operation. Through the setting of the width size adjustment mechanism, when the product reaches above the limit seat 513, the electric push rod 516 will clamp the product vertically downward.
