Description

Technical Field

[0001] This invention belongs to the field of UV coating of adhesive tape, specifically a UV coating device for adhesive tape. Background Technology

[0002] During the production of tape, adhesive needs to be applied to one or both sides of the tape. A tape coating machine is a device that applies adhesive to tape.

[0003] Existing coating equipment cannot customize the stroke of the adhesive applicator. Since existing coating equipment uses a sprayer to reciprocate and spray adhesive onto the tape, the stroke of the applicator will affect the thickness of the adhesive. The longer the stroke, the faster the applicator speed, but the thinner the adhesive. However, existing coating equipment often has to be coordinated with other equipment and cannot adjust the speed. Therefore, it is impossible to change the conveyor speed of the coating equipment to change the thickness of the tape, resulting in the coating equipment being able to produce only one specification of tape.

[0004] Therefore, we have made improvements to this and proposed a UV coating device for adhesive tape. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problem that current coating devices cannot customize the stroke of the adhesive applicator, which is why existing coating devices use a reciprocating sprayer to apply adhesive to the tape, the stroke of the applicator affects the thickness of the adhesive. The longer the stroke, the faster the coating speed, but the thinner the adhesive. However, existing coating devices often have to be coordinated with other equipment and cannot adjust the speed, so it is impossible to change the conveyor speed of the coating device to change the thickness of the tape. This results in the coating device only being able to produce one type of tape.

[0034] The specific workflow is as follows: First, the tape to be sprayed with adhesive is fixed on the conveyor roller 2005. Then, the second drive motor 2001 is started. The rotation of the second drive motor 2001 drives the first synchronous pulley 2002 to rotate. The rotation of the first synchronous pulley 2002 drives the second synchronous pulley 2003 to rotate through the synchronous belt 2004. The rotation of the second synchronous pulley 2003 drives the conveyor roller 2005 to rotate. The rotation of the conveyor roller 2005 drives the tape to move. The tape passes through two fourth connecting rods 2106, and then enters the heating chamber 2012 along with several first guide rollers 2007. The heating chamber 2012 can dry the adhesive on the tape. After passing through the second guide roller 2008, it is finally wound onto the take-up roller 2011. Then, the first drive motor 1107 is started. The rotation of the first drive motor 1107 drives the first turntable 1101 to rotate. The rotation of the first turntable 1101 drives the first connecting rod 1102 to swing. The swing of the first connecting rod 1102 drives the glue sprayer 1005 to move up and down reciprocally. Then, the glue sprayer 1005 sprays the tape. By starting the stepper motor 1108, the rotation of the stepper motor 1108 drives the second turntable 1104 to rotate. The rotation of the second turntable 1104 causes the third turntable 1105 and the first support frame 1006 to swing. Since the output shaft of the stepper motor 1108 is eccentrically connected to the second turntable 1104, when the second turntable 1104 swings upward, it drives the third turntable 1105 and the third connecting rod 1106 to swing upward. The third connecting rod 1106 drives the end of the first connecting rod 1102 near the third connecting rod 1106 to swing upward, while the end of the first connecting rod 1102 away from the third connecting rod 1106 swings downward, causing... The third link 1106 is moved away from the glue sprayer 1005, so that the swing amplitude of the first link 1102 is minimized, thus making the stroke of the glue sprayer 1005 the shortest. When the second turntable 1104 deflects downward, the second turntable 1104 drives the third turntable 1105 and the third link 1106 to deflect downward. The third link 1106 drives the end of the first link 1102 near the third link 1106 to deflect downward, while the end of the first link 1102 away from the third link 1106 deflects upward, so that the third link 1106 is close to the glue sprayer 1005, the swing amplitude of the first link 1102 is the largest, and the stroke of the glue sprayer 1005 is the longest. When it is necessary to adjust the maximum sprayable stroke of the tape or to adjust the tension of the tape, the cylinder 2108 is activated. The movement of the cylinder 2108 causes the floating joint 2109 and the third fixed seat 2102 to move. The movement of the third fixed seat 2102 causes the two fourth connecting rods 2106 on both sides of the third fixed seat 2102 to swing. The swing of the fourth connecting rods 2106 causes the two third guide wheels 2101 to move closer or further apart, thereby changing the maximum sprayable stroke of the tape. When the two third guide wheels 2101 move further apart, the tape can be tensioned. When the two third guide wheels 2101 move closer together, the tape can be relaxed.
