Description

Technical Field

[0001] This invention relates to the field of tape bonding technology, specifically to a tape bonding pressing roller spacing adjustment mechanism. Background Technology

[0002] The tape bonding field is an industrial application that tightly bonds tapes (adhesive tapes, double-sided tapes, functional tapes, etc.) to another material (called a "substrate," such as films, paper, metal foils, electronic components, composite materials, etc.) through physical pressing, chemical bonding, or thermal activation. Its core objective is to achieve reliable adhesion between the tape and the substrate to meet functional requirements such as "fixation, sealing, insulation, cushioning, conductivity, and thermal conductivity," making it a crucial link between "tape production" and "end-use applications."

[0003] For example, Chinese patent with publication number CN204622755U discloses a pressure roller fine adjustment mechanism on an adhesive applicator;

[0004] The technical solution described in this plan includes vertical mounting plates and pressure rollers fixed to both sides of the adhesive applicator frame. The upper end of the mounting plate has several vertical mounting holes. Lugs are fixed to the two side walls at the lower end of the mounting plate, and L-shaped adjusting plates are hinged to the lugs. The adjusting plates consist of a horizontal part and a vertical part. A vertical, waist-shaped hole is formed in the vertical part. A horizontal support plate is provided above the adjusting plate and is fixed to the mounting plate. A horizontal guide groove is formed on the support plate, and bolts are inserted into the guide groove. The lower ends of the bolts are fixed to the horizontal part of the adjusting plate, and adjusting nuts are screwed onto the bolts. The adjusting nuts are located below the support plate. Support shafts are formed at both ends of the pressure rollers, and the support shafts are inserted into the waist-shaped holes in the vertical part of the adjusting plate.

[0005] However, this solution requires sequential adjustment of both ends of the pressure roller, which is inefficient and inaccurate. It is also prone to uneven lifting and lowering of the two ends of the pressure roller, resulting in one side being higher than the other, causing uneven tape adhesion, affecting product quality, and making it inconvenient to use.

[0036] Specifically, the working principle of this tape bonding and pressing roller spacing adjustment mechanism is as follows: During use, the mounting hole 14 and the first bearing 13 facilitate the use of fixing bolts passing through the mounting hole 14 to securely connect the mounting base 12 to the bonding machine frame. The first bearing 13 supports the rotation of the threaded rod 110, reducing friction and ensuring smooth rotation. The mounting base 12 facilitates the fixed installation of the device to the bonding machine frame, allowing the pressing roller 21 to press the tape. The top plate 17 provides a mounting base for the threaded rod 110 in conjunction with the mounting base 12. The third bearing 18 works in conjunction with the first bearing 13 to ensure the threaded rod 110... The worm gear 114 rotates smoothly thanks to the second bearing 16, which supports its rotation. The worm wheel 111 drives the threaded rod 110. The synchronous shaft 113 synchronizes the rotation of both worm gears 114. The dial 116 indicates the rotation angle of the worm gear 114, indirectly reflecting the lifting distance of the pressing roller 21. The pointer 112 points to the angle scale on the dial 116, visually displaying the rotation angle of the worm gear 114 and aiding in precise adjustment. The meshing connection between the worm gear 114 and the worm wheel 111 facilitates the smooth rotation of both worm gears 114. The synchronous rotation of shaft 14 causes the worm gear 111 to drive the two threaded rods 110 to rotate synchronously. The handle 115 facilitates the control of the synchronous shaft 113's rotation. The bearing seat 22 provides a mounting base for the pressing roller 21, allowing it to press the tape. The lifting block 26 controls the raising and lowering of the pressing roller 21, thus adjusting the spacing between them. The second threaded sleeve 29 is threadedly connected to the threaded rod 110, facilitating the synchronous rotation of the two threaded rods 110 to control the synchronous raising and lowering of both ends of the pressing roller 21. This results in high adjustment efficiency and effective... To avoid asynchronous lifting at both ends, the tape bonding quality is improved. The guide slider 27 is slidably connected to the guide groove 19, which facilitates the limiting and guiding of the lifting block 26's rise and fall, ensuring that the lifting block 26's rise and fall are stable and accurate. The fourth bearing 23 facilitates the free rotation of the pressing roller 21, reduces friction, and ensures smooth rotation. The hexagonal head 25 facilitates the use of a wrench to control the rotation of the fine-tuning screw 24. The first threaded sleeve 28 is threadedly connected to the fine-tuning screw 24, which facilitates the rotation of the fine-tuning screw 24, allowing for a small range of adjustment of the height of the corresponding bearing seat 22, thereby adjusting one end of the pressing roller 21 and ensuring that the pressing roller 21 is horizontal.
