[0027] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figure 1-2 As shown, the utility model provides a coating device for uniformly coating self-adhesive labels with silicone glue, including a base 1, a spraying mechanism installed on the base 1, a plurality of nozzles 202 arranged on the spraying mechanism, the spraying mechanism including a spraying box 2 fixedly installed on the base 1, a glue inlet pipe 201 fixedly installed on the spraying box 2 and connected to the spraying box 2, and a plurality of nozzles 202 arranged in a linear array at the bottom of the spraying box 2 and connected to the spraying box 2. An external glue source enters the interior of the spraying box 2 through the glue inlet pipe 201, and then is sprayed out through the plurality of nozzles 202.

[0030] like Figure 1-2 and Figure 6 As shown, it also includes a range adjustment component, which is installed on the spraying mechanism, and the range adjustment component controls the open and blocked state of the nozzle 202. The range adjustment component includes baffles 203 slidably installed on both sides of the inside of the spray box 2, a connecting rod 204 fixedly installed on the baffle 203 and extending through one side of the spray box 2 to the outside of the spray box 2, a connecting block 205 fixedly installed on the connecting rod 204, a first motor 206 fixedly installed on the base 1, a bidirectional screw 207 rotatably installed on the base 1 and fixedly connected to the output shaft of the first motor 206, and two connecting blocks 205 are threadedly connected to both sides of the bidirectional screw 207. Starting the first motor 206 drives the bidirectional screw rod 207 to rotate, which can drive the connecting block 205 to move, thereby making the two baffles 203 approach or move away from each other. The nozzle 202 located between the two baffles 203 can spray normally, while the nozzle 202 located on the outside between the two nozzles 202 cannot spray because the baffle 203 blocks the glue, thereby achieving the adjustment of the spraying range.

[0031] Among them, both sides of the bidirectional screw rod 207 are threadedly connected with a splash plate 208, and the splash plate 208 is located below the spray box 2 and the nozzle 202. The splash plate 208 prevents the glue sprayed from the nozzle 202 from spreading outward.

[0032] like Figure 1-5As shown, it also includes an equalizing mechanism, which is installed on the base 1 and located below the nozzle 202. The equalizing mechanism receives the glue sprayed from the nozzle 202 and evenly distributes the glue. The equalizing mechanism includes a first equalizing roller 3, a second equalizing roller 301, and a third equalizing roller 302 rotatably installed on the base 1. The first equalizing roller 3 is located directly below the nozzle 202. The first equalizing roller 3 and the second equalizing roller 301 are in contact with each other, and the second equalizing roller 301 and the third equalizing roller 302 are in contact with each other. It also includes a driving mechanism for driving the first equalizing roller 3, the second equalizing roller 301, and the third equalizing roller 302 to rotate. The glue sprayed from the nozzle 202 will fall onto the first spreading roller 3. The driving mechanism drives the first spreading roller 3, the second spreading roller 301 and the third spreading roller 302 to rotate synchronously, so that the glue on the first spreading roller 3 can be brought into contact with the second spreading roller 301. Through the extrusion between the first spreading roller 3 and the second spreading roller 301, the glue can be attached to the second spreading roller 301 and flattened. Then, the glue on the second spreading roller 301 is brought into contact with the third spreading roller 302 again, so that the glue on the second spreading roller 301 adheres to the third spreading roller 302 and is flattened again, so that the glue on the third spreading roller 302 can be flat and the glue coating can be uniform.

[0033] Furthermore, a gap is left between the first spreading roller 3 and the second spreading roller 301, which is the thickness of the glue after the first spreading. A gap is also provided between the second spreading roller 301 and the third spreading roller 302 for allowing the glue to pass through, preventing the glue from being squeezed to the outside of the first spreading roller 3, the second spreading roller 301 and the third spreading roller 302.

[0034] Two groups of telescopic rods 6 are fixedly installed on the base 1, and two springs 602 are fixedly installed on both sides of the base 1. A support seat 601 is fixedly installed on the same group of telescopic rods 6, and the support seat 601 is fixedly connected to the spring 602. The driving roller 4 is rotatably installed on the two support seats 601. The driving roller 4 is located directly below the third evenly spreading roller 302. The driving roller 4 drives the label to move, and the driving roller 4 is connected to the driving mechanism. Under the action of the spring 602, the driving roller 4 is pressed against the third evenly spreading roller 302, and the driving mechanism can drive the driving roller 4 and the third evenly spreading roller 302 to move toward each other. Placing the label between the driving roller 4 and the third evenly spreading roller 302 can drive the label to move, and then the glue on the third evenly spreading roller 302 can be attached to the label, thereby completing the gluing of the label.

[0035] Among them, the driving mechanism includes a second motor 507 fixedly mounted on the base 1, a first gear 5 fixedly mounted on the first balancing roller 3, a second gear 501 fixedly mounted on the second balancing roller 301, a third gear 502 fixedly mounted on the first gear 5, a fourth gear 503 fixedly mounted on the third balancing roller 302, a first reversing gear 508 fixedly mounted on the driving roller 4, a second reversing gear 509 rotatably mounted on the support seat 601, a first pulley 504 fixedly mounted on the second reversing gear 509, a second pulley 505 fixedly mounted on the fourth gear 503, a transmission belt 506 arranged on the first pulley 504 and the second pulley 505, the output shaft of the second motor 507 is coaxially fixedly connected to the driving roller 4, the first gear 5 and the second gear 501 are meshed with each other, the third gear 502 and the fourth gear 503 are meshed with each other, and the first reversing gear 508 and the second reversing gear 509 are meshed with each other. The driving roller 4 is driven to rotate by the second motor 507, the first pulley 504 is rotated by the first reversing gear 508 and the second reversing gear 509, the second pulley is rotated by the transmission belt 506, and then the third averaging roller 302 is rotated. The direction of the third averaging roller 302 is opposite to that of the driving roller 4, which can apply thrust to the label. The third averaging roller 302 can drive the second averaging roller 301 and the first averaging roller 3 to rotate synchronously.

[0036] like Figure 1 and Figure 5 As shown, it also includes a tensioning mechanism, which prevents the transmission belt 506 from loosening. The tensioning mechanism includes a column 7 fixedly mounted on the base 1, a support plate 701 fixedly mounted on the column 7, a telescopic column 702 fixedly mounted on the support plate 701, a mounting seat 704 fixedly mounted on the telescopic column 702, a pressure spring 703 fixedly mounted between the support plate 701 and the mounting seat 704, and a tensioning wheel 705 rotatably mounted on the mounting seat 704, and the tensioning wheel 705 abuts against the transmission belt 506. Under the action of the pressure spring 703, the transmission belt 506 can be prevented from loosening, thereby ensuring the transmission effect.

[0037] Working principle: The external glue source enters the spray box 2 through the glue inlet pipe 201, and then is sprayed out through multiple nozzles 202. The glue sprayed from the nozzle 202 will fall onto the first spreading roller 3, and the first spreading roller 301 and the third spreading roller 302 are driven by the driving mechanism to rotate synchronously, so that the glue on the first spreading roller 3 can be brought into contact with the second spreading roller 301, and the glue can be adhered to the second spreading roller 301 through the extrusion between the first spreading roller 3 and the second spreading roller 301, and the glue is flattened, and then the glue on the second spreading roller 301 is brought into contact with the third spreading roller 302 again, so that the glue on the second spreading roller 301 is adhered to the third spreading roller 302, and the glue is flattened again, so that the glue on the third spreading roller 302 can be flat, and the glue coating can be uniform, and the driving roller 4 and the third spreading roller 302 can be driven by the driving mechanism to move toward each other, and the label is placed between the driving roller 4 and the third spreading roller 302, which can drive the label to move, and then the glue on the third spreading roller 302 can be adhered to the label, thereby completing the gluing of the label.
