[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1 Please see Figure 1-5 A plastic product processing adhesive coating device includes a support base 1, an adhesive coating rack 2, and a drying rack 3. The support base 1 has a moving groove 4 on its top surface, and a feeding component 5 is connected to the moving groove 4. The adhesive coating rack 2 is connected to an adhesive coating component 6, and the drying rack 3 is connected to a drying component 7. The adhesive coating rack 2 and the drying rack 3 are both mounted above the moving groove 4 and fixedly connected to the top surface of the support base 1. The feeding component 5 includes a feeding plate 505, which is used to drive the feeding plate 505 to pass through the adhesive coating component 6 and the drying component 7 in sequence, and to perform adhesive coating and drying in sequence. The adhesive coating component 6 is used to apply adhesive to the surface of the plastic product in a quantitative manner to ensure the uniformity of the product.

[0022] The feeding assembly 5 includes a feeding motor 501, a feeding screw 502, a feeding screw block 503, a rotating column 504, and a feeding plate 505. The feeding motor 501 is fixedly connected to the side of the support base 1. The output shaft of the feeding motor 501 is fixedly connected to the feeding screw 502. The end of the feeding screw 502 extends into the moving groove 4 and is rotatably connected to the other side wall of the moving groove 4. The feeding screw block 503 is threadedly connected to the feeding screw 502. The rotating column 504 is rotatably connected to the top surface of the feeding screw block 503. The feeding plate 505 is fixedly connected to the top surface of the rotating column 504.

[0024] The plastic product to be coated is placed on the feeding plate 505. The fixing cylinder 507 is activated, driving the fixing plate 508 to descend and firmly fix the plastic product on the feeding plate 505. The feeding motor 501 is started, which drives the feeding screw 502 to rotate, causing the feeding screw block 503 to move along the moving groove 4 towards the coating rack 2, thereby moving the feeding plate 505 and the plastic product on it towards the coating station.

[0025] The glue application assembly 6 includes a glue supply tank 601, a stirring motor 602, a stirring rod 603, stirring blades 604, a glue supply pipe 605, a mounting bracket 606, a metering tube 607, a drive cylinder 608, a glue pushing piston 609, a glue outlet pipe 610, a glue application head 611, a first one-way check valve 612, and a second one-way check valve 613. The glue supply tank 601 is fixedly connected to the top surface of the glue application frame 2. The stirring rod 603 is rotatably connected to the bottom surface of the glue supply tank 601. The upper end of the stirring rod 603 extends above the glue supply tank 601 and is fixedly connected to the output shaft of the stirring motor 602. Several sets of evenly distributed stirring blades 604 are fixedly connected to the stirring rod 603. The mounting bracket is fixedly connected to the top surface of the glue application frame 2. 606. A metering tube 607 is fixedly connected to the mounting bracket 606. A drive cylinder 608 is fixedly connected to the inner side of the glue applicator 2. The front end of the piston rod of the drive cylinder 608 extends into the metering tube 607 and is fixedly connected to a pusher piston 609. The pusher piston 609 matches the inner wall of the metering tube 607. A glue supply tube 605 and a glue outlet tube 610 are fixedly connected to the top and bottom surfaces of the metering tube 607 away from the drive cylinder 608, respectively. The other end of the glue supply tube 605 passes through the top surface of the glue applicator 2 and extends into the glue supply box 601. A glue applicator head 611 is fixedly connected to the lower end of the glue outlet tube 610. A first one-way check valve 612 is provided on the glue supply tube 605, and a second one-way check valve 613 is provided on the glue outlet tube 610.

[0026] The glue application assembly 6 also includes a rotating motor 614, a rotating gear 615, a gear ring 616, a signal transmitter 617, and a signal receiver 618. The rotating motor 614 is fixedly connected to the side of the feeding screw block 503. The rotating gear 615 is fixedly connected to the output shaft of the rotating motor 614. The gear ring 616 is fixedly connected to the rotating column 504. The gear ring 616 and the rotating gear 615 mesh with each other. The signal transmitter 617 is fixedly connected to the top surface of a set of inverted L-shaped plates 506. The signal receiver 618 is fixedly connected to the inner top surface of the glue application frame 2. The signal receiver 618 is electrically connected to the rotating motor 614.

[0027] During the feeding process, the stirring motor 602 operates continuously, driving the stirring blades 604 to rotate via the stirring rod 603, thus stirring the glue in the glue supply tank 601 and preventing sedimentation and stratification. The drive cylinder 608 retracts, causing the glue-pushing piston 609 to retract within the metering tube 607. At this time, the first one-way check valve 612 opens, and the second one-way check valve 613 closes. Through the pressure difference, the glue in the glue supply tank 601 enters the metering tube 607 through the glue supply pipe 605, completing the glue suction process.

[0028] When the feeding plate 505 moves to the glue application station, the signal transmitter 617 aligns with the signal receiver 618. After receiving the signal, the signal receiver 618 stops the feeding motor 501 and starts the rotary motor 614. The rotary motor 614 drives the rotating column 504 and the feeding plate 505 to rotate through the rotating gear 615 and gear ring 616, causing the plastic product to rotate accordingly. The drive cylinder 608 extends, pushing the glue-pushing piston 609 forward in the metering tube 607. At this time, the first one-way check valve 612 closes and the second one-way check valve 613 opens. The glue in the metering tube 607 is squeezed out from the glue application head 611 through the glue outlet tube 610. The plastic product rotates, and the glue is evenly applied to the surface of the rotating plastic product.

[0029] Example 2 This embodiment adds the following improvements to Embodiment 1: The drying assembly 7 includes a drying vertical rod 701, a transmission wheel 702, a transmission belt 703, drying blades 704, and a heating box 705. The drying vertical rod 701 is rotatably connected to the top of the drying rack 3. The lower end of the drying vertical rod 701 extends into the drying rack 3 and is fixedly connected to the drying blades 704. The upper end of the drying vertical rod 701 and the stirring vertical rod 603 are both fixedly connected to the transmission wheel 702. The transmission wheels 702 are connected to each other by the transmission belt 703. The heating box 705 is fixedly connected inside the drying rack 3 and is located below the drying blades 704.

[0030] After the adhesive is applied, the rotating motor 614 stops, and the feeding motor 501 restarts, sending the feeding plate 505 and the coated plastic product into the drying rack 3. The stirring rod 603 drives the drying rod 701 to rotate via the transmission wheel 702 and the transmission belt 703, thereby causing the drying blades 704 to rotate. The heating box 705 generates heat, which, under the action of the drying blades 704, is evenly blown onto the surface of the plastic product, accelerating the drying of the adhesive. After drying, the feeding assembly 5 sends the plastic product out of the drying rack 3, and the fixing cylinder 507 drives the fixing plate 508 to rise, releasing the plastic product and completing the entire adhesive application and drying process.
