[0024] Embodiment Ribbon bonding and cutting device

[0025] In this embodiment, Figure 1 , Figure 2 As shown, a webbing bonding and cutting device comprises a frame 1, on which a first unwinding shaft 2 and a second unwinding shaft 3 parallel to each other are detachably provided, and two synchronous bonding rollers 9 are rotatably provided on one side of the two unwinding shafts, and the roller shafts of the synchronous bonding rollers 9 are rotatably provided on the frame 1 and connected through a transmission mechanism, and the synchronous bonding rollers 9 are driven by a driving device, and a cutter 14 is fixedly provided on the side of the synchronous bonding rollers 9 away from the first unwinding shaft 2 and the second unwinding shaft 3.

[0026] Specifically, the side surface of the frame body 1 in this embodiment is in a "U" shape, including two side walls arranged in the up and down direction and a bottom wall in the horizontal direction. Removably arranged on the frame body 1 are the first unwinding shaft 2 and the second unwinding shaft 3 which are parallel to each other, and the first unwinding shaft 2 and the second unwinding shaft 3 are arranged in the height direction. A limiting block 4 with a diameter larger than that of the unwinding shaft is fixedly provided at one end of either the first unwinding shaft 2 or the second unwinding shaft 3. The first unwinding shaft 2 and the second unwinding shaft 3 penetrate through the two side walls of the frame body 1 and are arranged on the frame body 1. A clamp 5 for preventing the unwinding shaft from falling off is arranged at the other end of the first unwinding shaft 2 and the second unwinding shaft 3, and the first unwinding shaft 2 and the second unwinding shaft 3 are rotatably arranged on the frame body 1. The webbing bonding and cutting device in this embodiment is used to bond and cut the webbing 16 and the double-sided tape 17 together. Therefore, the first unwinding shaft 2 is used to sleeved with the webbing 16, and the second unwinding shaft 3 is used to sleeved with the double-sided tape 17. Since the webbing 16 is in a coiled structure without an inner core and the first unwinding shaft 2 is made of metal, one end of the first unwinding shaft 2 where the clamp 5 is arranged is a tip, and the webbing 16 can be directly sleeved on the first unwinding shaft 2 through the tip. And because the friction between the metal and the webbing 16 is small, the first unwinding shaft 2 can rotate relative to the bracket or be fixed relative to the bracket. The second unwinding shaft 3 is used to sleeved with the double-sided tape 17. Since the double-sided tape 17 has an inner core and a larger inner diameter, a scroll roller 6 with a larger diameter is fixedly provided on the second unwinding shaft 3, and the double-sided tape 17 is sleeved on the scroll roller 6, and the second unwinding shaft 3 can rotate relative to the frame body 1. During application, the scroll roller 6 can be sleeved accordingly according to the inner diameters of the materials sleeved on the first unwinding shaft 2 and the second unwinding shaft 3. The first unwinding shaft 2 and the second unwinding shaft 3 have a certain length, so that multiple pairs of webbing 16 and double-sided tape 17 can be sleeved on the same pair of unwinding shafts. When multiple pairs of webbing 16 and double-sided tape 17 can be sleeved on the same pair of unwinding shafts, the centering of the webbing 16 and the double-sided tape 17 needs to be ensured. A number of second spacer sheets 7 penetrating through the first unwinding shaft 2 and the second unwinding shaft 3 are sleeved on the first unwinding shaft 2 and the second unwinding shaft 3. The second spacer sheet 7 is in an "8" shape, penetrates through both unwinding shafts at the same time and does not affect the normal rotation of the unwinding shaft. The number of the second spacer sheets 7 is one more than the number of the webbing 16 or the double-sided tape 17. In order to fix the relative positions of the second spacer sheets 7, at both ends of a number of the second spacer sheets 7 on the first unwinding shaft 2, fixing blocks 8 are fixedly sleeved. The fixing blocks 8 adopt a structure with a certain elasticity, and the aperture of the holes opened on the fixing blocks 8 is slightly smaller than the outer diameter of the first unwinding shaft 2. In this embodiment, the material of the fixing blocks 8 is foam.

[0027] Two synchronous bonding rollers 9 arranged along the height direction are rotatably provided on one side of the two unwinding shafts. The roller axes of the synchronous bonding rollers 9 are arranged parallel to the first unwinding shaft 2 and the second unwinding shaft 3. The roller diameters of the two synchronous bonding rollers 9 are the same, and the outer surfaces are made of rubber. The spacing between the outer surfaces is smaller than the sum of the single-layer thicknesses of the materials on the first unwinding shaft 2 and the second unwinding shaft 3, so that the synchronous bonding rollers 9 have a certain extrusion pressure on the bonded materials, making the bonding more complete. Since the synchronous bonding roller 9 has a certain length, multiple bonded ribbons 16 can pass through the synchronous bonding roller 9 at the same time. In order to ensure the centering, the synchronous bonding roller 9 at the lower end is fixed with a plurality of first isolation sheets 10 along the radial direction of the roller. The outer edge of the first isolation sheet 10 is a circle coaxial with the synchronous bonding roller 9. The height of the first isolation sheet 10 is greater than the distance between the outer surfaces of the two synchronous bonding rollers 9. The other synchronous bonding roller 9 is provided with an annular groove 11 that is adapted to the first isolation sheet 10. The adaptation here means that the depth of the annular groove 11 is equal to the difference in distance between the first isolation sheet 10 and the outer surfaces of the two synchronous bonding rollers 9, so that the first isolation sheet 10 just extends into the annular groove 11 when the synchronous bonding roller 9 rolls.

[0028] The roller shafts of the two synchronous bonding rollers 9 are rotatably arranged on the frame 1 and connected through a transmission mechanism, and the synchronous bonding rollers 9 are driven by a driving device. The transmission mechanism in this embodiment includes a transmission gear 12 fixed on the roller shaft of the synchronous bonding roller 9. The two transmission gears 12 are exactly the same and mesh with each other. Of course, the transmission mechanism can also be a transmission belt, etc., as long as the transmission mechanism ensures that the rotation speeds of the two synchronous bonding rollers 9 are the same. A rocker 13 is connected to the axle of one of the transmission gears 12. When in use, the two synchronous bonding rollers 9 can be rotated synchronously by turning the rocker 13. Of course, a motor can also be used instead of the rocker 13 to drive, so as to realize automatic bonding of the webbing 16.

[0029] A cutter 14 is fixedly provided on one side of the synchronous bonding roller 9 away from the first unwinding shaft 2 and the second unwinding shaft 3. The setting direction of the cutter 14 is parallel to the synchronous bonding roller 9. When the bonded ribbon 16 is sent out from the synchronous bonding roller 9, the cutter 14 can be used to cut multiple synchronous bonding rollers 9 at one time. A scale line 15 for measuring the length of the material is set downstream of the cutter 14 on the frame 1 along the material conveying direction. The ribbons 16 of different lengths can be cut according to the scale line 15. The frame 1 where the scale line 15 is set only retains the bottom wall, and no side wall is set.

[0030] When using this embodiment, open the clamp 5, pull out the first unwinding shaft 2 and the second unwinding shaft 3, and sleeve the webbing 16 and the double-sided adhesive tape 17 on them, sleeve the second isolation sheet 7 between the ends of the materials and the adjacent two materials, and after installation, pass the first unwinding shaft 2 and the second unwinding shaft 3 through the side wall of the frame 1, fasten the clamp 5, extend the ends of the webbing 16 and the double-sided adhesive tape 17 between the synchronous bonding rollers 9, turn the rocker 13 to rotate the synchronous bonding rollers 9, and the bonded webbing 16 is output from the synchronous bonding rollers 9. Observe the output webbing 16 and the scale line 15. When the output webbing 16 reaches the specified length, stop turning the rocker 13, use the cutter 14 to cut the bonded webbing 16, and continue to turn the rocker 13 after cutting until the output webbing 16 reaches the specified length again and then cuts, and repeat the above steps until the webbing 16 is completely bonded and cut. It should be noted that the webbing 16 or the double-sided adhesive tape 17 can be replaced with other roll materials according to actual production conditions.
