Description

Technical Field

[0001] This utility model relates to the field of double-sided adhesive slicing technology, and in particular to a double-sided adhesive production slicing machine. Background Technology

[0002] Standard-sized double-sided tape is being used more and more frequently in modern electronics manufacturing. The current processing method for double-sided tape is to select a large piece of release paper or release film, attach the tape layer by layer onto the release paper or release film, and then use a die to cut out standard-sized double-sided tape from the large piece of tape, one cut at a time.

[0003] A patent with publication number CN212020872U discloses a slicing machine for double-sided adhesive production. The slicing machine includes a frame, a motor, a drive unit, a clamping assembly, a blade, a first guide roller, and a second guide roller. The blade is vertically mounted on the frame. The first guide roller and the second guide roller are mounted opposite each other on the frame. The first guide roller has connecting parts at both ends and can rotate relative to the connecting parts. The end of the connecting part facing away from the guide roller is hinged to the frame. The clamping assembly is used to provide a force to bring the first guide roller close to the second guide roller.

[0004] When cutting existing double-sided tape, the surface of the tape is not protected. As a result, when the cutting blade comes into contact with the tape, the sticky adhesive on the tape surface will adhere to the cutting blade surface. Consequently, after the cutting blade has finished cutting, the adhesive will move along with the tape as the cutting blade moves, causing the tape to shift in position. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem in the prior art that the adhesive on the surface of the double-sided tape will stick to the surface of the cutting blade, and thus the double-sided tape will shift position as the cutting blade moves.

[0006] To solve the above-mentioned technical problems, this utility model provides a double-sided tape production slicing machine, including a processing table and a support frame detachably installed on the outer surface of the processing table, double-sided tape movably sleeved on the inner wall of the processing table, release paper set on the upper and lower surfaces of the double-sided tape, two sets of auxiliary rollers movably sleeved on the inner wall of the processing table at the upper and lower edges, the outer surface of the release paper movably overlapping the outer surface of the auxiliary rollers, an overlap strip fixedly installed on the inner wall of the processing table at the middle position, a cutting groove opened on the top surface of the overlap strip, and a hydraulic lifter fixedly installed on the top surface of the overlap strip at the two side edges, which is set on the inner wall of the processing table, and a cutting blade fixedly connected to the output end of the hydraulic lifter.

[0007] In one embodiment of the present invention, the bottom outer surface of the cutting blade is movably sleeved on the inner wall of the cutting groove, and a groove is formed on the top surface of the cutting blade.

[0008] In one embodiment of this utility model, a conveying roller is fixedly installed on the top left edge of the processing table, and the outer surface of the double-sided adhesive is movably attached to the outer surface of the conveying roller.

[0009] In one embodiment of the present invention, a lower conveying roller is provided on the outer surface of one end of the processing table and at the bottom edge of the conveying rubber roller, and an upper conveying roller is provided on the top surface of the processing table and at one side edge of the hydraulic lifter.

[0010] In one embodiment of the present invention, two sets of receiving rollers are provided on the outer surface of the processing table. One set of receiving rollers is located at the edge of the other side of the hydraulic lifter. The outer surface of the anti-stick paper is movably sleeved on the outer surfaces of the lower conveying roller and the upper conveying roller, respectively.

[0011] In one embodiment of the present invention, a support plate is fixedly installed on the outer right side surface of the processing table, and the outer surface of another set of collecting rollers is disposed on the outer surface of the support plate. The outer surfaces of the two sets of anti-stick paper are respectively movably sleeved on the outer surfaces of the two sets of collecting rollers.

[0012] In one embodiment of this utility model, a motor is fixedly installed on the top inner side wall of the support frame, an air pump is fixedly connected to the output end of the motor, an air suction pipe is fixedly connected to the output end of the air pump, and a hydraulic telescopic cylinder is provided on the outer surface of the air pump.

[0013] In one embodiment of this utility model, the other end of the suction pipe is disposed on the input end of the hydraulic telescopic cylinder, and the bottom end of the hydraulic telescopic cylinder is provided with a flexible head that movably overlaps the outer surface of the release paper.

[0014] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0015] The present invention discloses a double-sided tape production slicing machine. The double-sided tape is pulled out from the surface of the conveying roller, and the release paper on the outer surface of the upper conveying roller is also pulled out. The release paper on the outer surface of the upper conveying roller is then attached to the top outer surface of the double-sided tape. An auxiliary roller at the top presses the release paper, ensuring it adheres firmly to the top surface of the double-sided tape. The release paper on the outer surface of the lower conveying roller is then pulled out, overlapping the release paper with the outer surface of the auxiliary roller. Multiple auxiliary rollers tighten the release paper on the outer surface of the lower conveying roller, allowing it to overlap horizontally on the bottom surface of the double-sided tape. This prevents the surface of the auxiliary roller from failing to effectively adhere to the bottom surface of the double-sided tape during subsequent cutting, greatly reducing wrinkles on the auxiliary roller.

[0016] The double-sided tape production slicing machine of this utility model uses a hydraulic lifter to lower the cutting blade, thereby squeezing the double-sided tape. The cutting groove on the top surface of the overlap strip interlocks with the cutting blade to cut the surface of the double-sided tape. When the cutting blade squeezes the double-sided tape, it also attaches the release paper on the outer surface of the lower conveying roller to the bottom surface of the double-sided tape. This allows the top and bottom surfaces of the double-sided tape to be sealed after cutting, preventing the glue on the outer surface of the double-sided tape from adhering to the outer surface of the cutting blade.

[0017] This utility model describes a double-sided adhesive tape slicing machine. After the double-sided adhesive tape is cut, a motor drives an air pump to rotate, causing a hydraulic telescopic cylinder to extend and descend perpendicular to the top surface of the cutting blade. One end of the hydraulic telescopic cylinder passes through a slot on the top surface of the cutting blade, allowing the flexible adhesive head at one end to adhere to the surface of the release liner on the double-sided adhesive tape. As the flexible adhesive head deforms under pressure, the air pump draws gas from the inside of the suction pipe, absorbing the gas inside the hydraulic telescopic cylinder. The deformed flexible adhesive head reduces the gap at the adhesion point with the release liner, and the negative pressure firmly adheres the release liner to the surface of the flexible adhesive head. The retracted hydraulic telescopic cylinder removes the release liner and double-sided adhesive tape from the top of the overlap strip. As the air pump continues to rotate, other hydraulic telescopic cylinders can effectively extract different types of double-sided adhesive tape. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1 - Figure 5As shown, this utility model discloses a double-sided adhesive tape production slicing machine, including a processing table 11 and a support frame 12 detachably mounted on the outer surface of the processing table 11. Double-sided adhesive tape 13 is movably sleeved on the inner wall of the processing table 11. Release paper 14 is disposed on the upper and lower surfaces of the double-sided adhesive tape 13. Two sets of auxiliary rollers 114 are movably sleeved on the inner wall of the processing table 11 at the upper and lower edges. The outer surface of the release paper 14 movably overlaps the outer surface of the auxiliary rollers 114. An overlapping strip 117 is fixedly installed on the inner wall of the processing table 11 at the middle position. A cutting groove 118 is formed on the top surface of the overlapping strip 117. A hydraulic lifter 119, which is set on the inner wall of the processing table 11, is fixedly installed on the top surface of the overlapping strip 117 at the two side edges. A cutting blade 1110 is fixedly connected to the output end of the hydraulic lifter 119. The bottom outer surface of the cutting blade 1110 is movably sleeved on the inner wall of the cutting groove 118. The top surface of the cutting blade 1110... A slot is provided on the upper part of the processing table 11. A conveying roller 113 is fixedly installed on the top left edge of the processing table 11. The outer surface of the double-sided adhesive 13 is movably attached to the outer surface of the conveying roller 113. A lower conveying roller 116 is provided on the outer surface of one end of the processing table 11, located at the bottom edge of the conveying roller 113. An upper conveying roller 115 is provided on the top surface of the processing table 11, located at one edge of the hydraulic lifter 119. Two sets of receiving rollers 1 are provided on the outer surface of the processing table 11. 12. A set of collecting rollers 112 is positioned on the other side edge of the hydraulic lifter 119. The outer surface of the anti-stick paper 14 is movably sleeved on the outer surface of the lower conveying roller 116 and the upper conveying roller 115, respectively. A support plate 111 is fixedly installed on the right outer surface of the processing table 11. The outer surface of another set of collecting rollers 112 is positioned on the outer surface of the support plate 111. The outer surfaces of the two sets of anti-stick paper 14 are movably sleeved on the outer surfaces of the two sets of collecting rollers 112, respectively.

[0027] The double-sided adhesive 13 is pulled out from the surface of the conveying roller 113, and the release paper 14 on the outer surface of the upper conveying roller 115 is pulled out. The release paper 14 on the outer surface of the upper conveying roller 115 is attached to the top outer surface of the double-sided adhesive 13, and the release paper 14 is squeezed by the top auxiliary roller 114 so that the release paper 14 can be firmly adsorbed on the top surface of the double-sided adhesive 13. The release paper 14 on the outer surface of the lower conveying roller 116 is pulled out so that the release paper 14 overlaps the outer surface of the auxiliary roller 114. The release paper 14 on the outer surface of the lower conveying roller 116 is tightened by multiple auxiliary rollers 114 so that the release paper 14 can be horizontally overlapped on the bottom surface of the double-sided adhesive 13. This avoids the surface of the auxiliary roller 114 from not being able to effectively adhere to the bottom surface of the double-sided adhesive 13 when cutting the double-sided adhesive 13 later, and greatly reduces the wrinkling effect of the auxiliary roller 114.

[0028] The cutting blade 1110 is lowered by the hydraulic lifter 119 to compress the double-sided tape 13. The cutting groove 118 on the top surface of the overlap strip 117 interlocks with the cutting blade 1110 to cut the surface of the double-sided tape 13. When the cutting blade 1110 compresses the double-sided tape 13, the release paper 14 on the outer surface of the lower conveyor roller 116 is attached to the bottom surface of the double-sided tape 13. This allows the upper and lower surfaces of the double-sided tape 13 to be sealed after cutting, preventing the glue on the outer surface of the double-sided tape 13 from adhering to the outer surface of the cutting blade 1110.

[0029] Reference Figure 1 and Figure 5 As shown, in one embodiment of the present invention, a motor 121 is fixedly installed on the inner side wall of the top of the support frame 12, a vacuum pump 122 is fixedly connected to the output end of the motor 121, a suction pipe 123 is fixedly connected to the output end of the vacuum pump 122, a hydraulic telescopic cylinder 124 is provided on the outer surface of the vacuum pump 122, the other end of the suction pipe 123 is provided on the input end of the hydraulic telescopic cylinder 124, and a soft head 125 that is movably overlapped on the outer surface of the release paper 14 is provided on the bottom end of the hydraulic telescopic cylinder 124.

[0030] After the surface of the double-sided tape 13 is cut, the motor 121 rotates the vacuum pump 122, causing a hydraulic telescopic cylinder 124 to be perpendicular to the top surface of the cutter 1110. The cylinder extends and descends, with one end passing through a slot on the top surface of the cutter 1110. The flexible adhesive head 125 at one end of the cylinder 124 adheres to the surface of the release liner 14 on top of the double-sided tape 13. As the flexible adhesive head 125 deforms under pressure, the vacuum pump 122... 2. The gas inside the suction pipe 123 is absorbed, so that the gas inside the hydraulic telescopic cylinder 124 is absorbed. The deformed bonding soft head 125 can reduce the gap at the bonding point with the release paper 14. At the same time, the negative pressure makes the release paper 14 firmly adhere to the surface of the bonding soft head 125. The retracted hydraulic telescopic cylinder 124 can remove the release paper 14 and double-sided adhesive 13 from the top of the overlap strip 117. As the air pump 122 continues to rotate, other hydraulic telescopic cylinders 124 can effectively extract different double-sided adhesives 13.

[0031] After the double-sided tape 13 is cut, it is wound up with the storage roller 112. At this time, the drop difference between the two storage rollers 112 is used to peel the release paper 14 on the bottom surface of the double-sided tape 13 off the surface of the double-sided tape 13. The top storage roller 112 then winds up the double-sided tape 13. The adhesive on the surface of the double-sided tape 13 is then used to stick and absorb it together. Finally, the bottom storage roller 112 collects the release paper 14 on the bottom surface of the double-sided tape 13.

[0032] Working principle: The double-sided adhesive 13 is pulled out from the surface of the conveying roller 113, and the release paper 14 on the outer surface of the upper conveying roller 115 is pulled out. The release paper 14 on the outer surface of the upper conveying roller 115 is attached to the top outer surface of the double-sided adhesive 13. The release paper 14 is squeezed by the top auxiliary roller 114, so that the release paper 14 can be firmly adhered to the top surface of the double-sided adhesive 13. The release paper 14 on the outer surface of the lower conveying roller 116 is pulled out, so that the release paper 14 overlaps the outer surface of the auxiliary roller 114. The release paper 14 on the outer surface of the lower conveying roller 116 is tightened by multiple auxiliary rollers 114, so that the release paper 14 can be horizontally overlapped on the bottom surface of the double-sided adhesive 13. This avoids the surface of the auxiliary roller 114 from not being able to effectively adhere to the bottom surface of the double-sided adhesive 13 when cutting the double-sided adhesive 13 later, and greatly reduces the wrinkling effect of the auxiliary roller 114.

[0033] The cutting blade 1110 is lowered by the hydraulic lifter 119 to squeeze the double-sided tape 13. The cutting groove 118 on the top surface of the overlap strip 117 interlocks with the cutting blade 1110 to cut the surface of the double-sided tape 13. When the cutting blade 1110 squeezes the double-sided tape 13, the release paper 14 on the outer surface of the lower conveying roller 116 is attached to the bottom surface of the double-sided tape 13. This allows the upper and lower surfaces of the double-sided tape 13 to be sealed after cutting, preventing the glue on the outer surface of the double-sided tape 13 from sticking to the outer surface of the cutting blade 1110.

[0034] After the surface of the double-sided tape 13 is cut, the motor 121 rotates the vacuum pump 122, causing a hydraulic telescopic cylinder 124 to be perpendicular to the top surface of the cutter 1110. The cylinder extends and descends, with one end passing through a slot on the top surface of the cutter 1110. The flexible adhesive head 125 at one end of the cylinder 124 adheres to the surface of the release liner 14 on top of the double-sided tape 13. As the flexible adhesive head 125 deforms under pressure, the vacuum pump 122... 2. The air suction tube 123 absorbs gas, so that the gas inside the hydraulic telescopic cylinder 124 is absorbed. The deformed bonding soft head 125 can reduce the gap at the bonding point with the release paper 14. At the same time, the negative pressure makes the release paper 14 firmly adhere to the surface of the bonding soft head 125. The retracted hydraulic telescopic cylinder 124 can remove the release paper 14 and double-sided adhesive 13 from the top of the overlap strip 117. As the air pump 122 continues to rotate, other hydraulic telescopic cylinders 124 can effectively extract different double-sided adhesives 13.

[0035] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
