Description

Technical Field

[0001] The invention relates to the technical field of double-sided adhesive tape die-cutting, in particular to a double-sided adhesive tape die-cutting production process. Background Art

[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, or plastic film as the base material, with elastomeric pressure-sensitive adhesive or resin-based pressure-sensitive adhesive evenly coated on the above base material. It consists of three parts: base material, adhesive, and release paper (film). During the processing and production process, double-sided tape needs to be cut into products of different sizes and appearances to meet market demand.

[0003] The second tape is then recycled and the double-sided tape is cut to obtain a single double-sided tape product, which solves the problems of double-sided tape accumulation and low work efficiency in the existing double-sided tape die-cutting process.

[0004] However, the existing technology still has major deficiencies, such as: 1. During use, the above-mentioned device can continuously cut the double-sided tape and the adhesive tape covering it into strips through the die cutter. However, when finally cutting the double-sided tape into rectangular shapes, it is necessary to manually cut the strips of double-sided tape into rectangular shapes, or stop the machine to cut the strips of double-sided tape into rectangular shapes. Otherwise, the strips of double-sided tape will accumulate, affecting the subsequent cutting of the strips of double-sided tape into rectangular shapes, resulting in reduced double-sided tape die-cutting efficiency. 2. During the use of the above device, a large amount of tape is required. The tape only plays a role of transportation in the device. Although it can reduce the dust on the double-sided tape, it causes waste of tape and increases the cost of using the device. Summary of the Invention

[0014] Preferably, a plurality of baffles are fixedly arranged above the collecting tank.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention first uses two laminating rollers to press a double-sided tape with a base tape on one side and another base tape to form a double-sided tape with base tape on both sides. Then, a stripping mechanism is used to cut the pressed double-sided tape into strips of double-sided tape. At the same time, a first motor drives a separating roller, a squeezing roller, and a cutting roller in the cutting mechanism to rotate via a belt to cut the strips of double-sided tape into rectangular blocks of finished double-sided tape. This process is a continuous process. The device can operate continuously and die-cut the double-sided tape without causing accumulation of the double-sided tape and without manual operation, thereby improving the efficiency of double-sided tape die-cutting. In addition, the base tape and the double-sided tape are pressed together at the beginning, and the double-sided tape is not contaminated by dust. 2. The present invention provides a collecting mechanism. When the separating roller, the squeezing roller and the cutting roller rotate to cut the double-sided adhesive tape strips, the blade on the cutting roller cuts the double-sided adhesive tape strips when in contact with the separating roller. The block-shaped double-sided adhesive tape falls down, and the subsequent double-sided adhesive tape strips may not adhere to the separating roller, which will affect the subsequent cutting of the double-sided adhesive tape strips. At this time, the suction pump sucks air and generates negative pressure through the arc-shaped suction groove, air channel and air hole. The double-sided adhesive strips can always be tightly attached to the separating roller before being cut by the blade on the cutting roller. In addition, the squeezing and rotation between the squeezing roller and the separating roller enable the double-sided adhesive tape strips cut by the slitting mechanism to be transferred between the separating roller and the cutting roller to be cut. Therefore, the double-sided adhesive tape does not need a carrier during the mobile conveying process, and does not need tape for transmission, thereby reducing the use cost. 3. The present invention provides a collecting device and utilizes an air pump to blow air into the air passages and air holes in the separation roller through the arc-shaped air blowing grooves, so as to separate the cut double-sided tape product from the separation roller without causing overlap of the double-sided tape, thereby not affecting the subsequent conveying of the strip double-sided tape by the separation roller. At the same time, the air pump blows air into the air passages and air holes in the cutting roller through the arc-shaped air blowing grooves and the circular air blowing grooves, thereby preventing the block double-sided tape product falling from the separation roller from falling onto the cutting roller and affecting the subsequent cutting by the cutting roller. In addition, when the blade on the cutting roller is about to cut, the air holes on the cutting roller near the separation roller will blow air outward, which can further make the strip double-sided tape to be cut on the separation roller close to the separation roller. 4. When the blade on the die-cutting cylinder is die-cutting the double-sided tape, a large amount of glue will remain on the blade, which will affect the subsequent cutting. The glue removal mechanism set at the slitting mechanism can continuously scrape off the glue on the blade of the die-cutting cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-9 , the present invention provides a technical solution: Example

[0020] A double-sided tape die-cutting production process includes an operating table 1 and support legs 2. The support legs 2 are fixedly arranged under the operating table 1 to lift the operating table 1 and can also be replaced by other adjustable support legs 2. A stripping mechanism for cutting the double-sided tape into strips is provided on the operating table 1. The stripping mechanism includes two first fixed plates 3 symmetrically fixedly arranged in the middle of the operating table 1. A die-cutting cylinder 4 and a pressure-cutting roller 5 are rotatably arranged between the two first fixed plates 3. The die-cutting cylinder 4 and the pressure-cutting roller 5 are respectively fitted with each other and have the same diameter. The die-cutting cylinder 4 is fixedly connected to a first motor 6, which is fixed to the first fixed plate 3 by bolts. When the first motor 6 drives the die-cutting cylinder 4 to rotate, the double-sided tape passes between the die-cutting cylinder 4 and the pressure-cutting roller 5. The annular blade on the die-cutting cylinder 4 can cut the double-sided tape into strips.

[0021] Two second fixed plates 7 are symmetrically fixed on one side of the operating table 1, and a double-sided tape unwinding roller 8 and a bottom tape unwinding roller 33 are rotatably arranged between the two second fixed plates 7. The double-sided tape unwinding roller 8 is wound with a double-sided tape with a bottom tape on one side, and the bottom tape unwinding roller 33 is wound with another bottom tape.

[0022] Two support plates 34 are symmetrically fixedly provided between the first fixed plate 3 and the second fixed plate 7 on the operating table 1. Two sliding grooves 35 are provided on the support plates 34. A sliding rod 36 is fixedly provided in the sliding groove 35. A movable shaft 37 is slidingly sleeved on the sliding rod 36. The movable shaft 37 is restricted by the sliding rod 36 and can only move up and down in the sliding groove 35. A tightening roller 38 is rotatably provided on the movable shaft 37. The sliding rod 36 is provided with a spring 2 39 under the movable shaft 37. The spring 2 39 will become longer to make the movable shaft 37 drive the tightening roller 38 to move upward together, thereby prompting the bottom belts on the two tightening rollers 38 and the double-sided tape with the bottom belt to always remain in a taut state, so that the bottom belt and the double-sided tape with the bottom belt will not overlap or bubble when they are subsequently pressed together.

[0023] The operating table 1 has two fourth fixed plates 40 symmetrically fixed between the first fixed plate 3 and the support plate 34, and two pressing rollers 41 are rotatably arranged between the two fourth fixed plates 40. A gear three 42 is fixedly arranged on one side of the two pressing rollers 41, and they are engaged with each other. When the base belt and the double-sided tape with the base belt on one side move from the middle of the two pressing rollers 41, the two pressing rollers 41 simultaneously rotate the base belt to press it onto the double-sided tape with the base belt, so that the base belt is adhered to both sides of the double-sided tape. This prevents the double-sided tape from being contaminated by dust, and also prevents the double-sided tape from sticking to other parts and affecting cutting during the subsequent transportation.

[0024] The operating table 1 has two fifth fixed plates 43 symmetrically fixed between the first fixed plate 3 and the collecting trough 27. Two smoothing rollers 44 are rotatably arranged between the two fifth fixed plates 43. A gear 45 is fixedly arranged on one side of the two smoothing rollers 44, and the two smoothing rollers 44 are meshed with each other. When the double-sided tape is cut into strips of double-sided tape by the die-cutting cylinder 4, it passes through the middle of the two smoothing rollers 44 to prevent the strips of double-sided tape from twisting or overlapping, thereby facilitating subsequent cutting.

[0025] A winding roller 46 is also rotatably arranged between the two first fixed plates 3. The winding roller 46 is fixedly connected to the second motor 47. The second motor 47 is fixed to the first fixed plate 3 by bolts. The waste remaining after the double-sided tape is cut by the die-cutting knife cylinder 4 is wound around the winding roller 46. The winding roller 46 is driven to rotate by the second motor 47 to rewind the waste. Example

[0026] The operating table 1 is provided with a dividing mechanism for cutting the strip double-sided tape into pieces. The dividing mechanism includes two third fixed plates 9 symmetrically fixedly arranged on one side of the operating table 1 away from the second fixed plate 7. A separating roller 10, an extruding roller 11 and a cutting roller 12 are respectively rotated between the two third fixed plates 9. The separating roller 10 and the extruding roller 11 are arranged in parallel and squeeze each other. The cutting roller 12 is arranged below the separating roller 10. The diameters of the separating roller 10, the extruding roller 11 and the cutting roller 12 are the same as the diameter of the die-cutting knife cylinder 4. A plurality of grooves are provided on the separating roller 10 to cut the strip double-sided tape into pieces. The strips of double-sided tape on the separating roller 10 are arranged in sequence in the groove. The squeezing roller 11 is provided with several convex rings, which correspond to the grooves on the separating roller 10, and can extrude the strips of double-sided tape on the separating roller 10. The cutting roller 12 is provided with several short blades. The length of the short blades is the same as the width of the groove on the separating roller 10. The strips of double-sided tape on the separating roller 10 are cut to form a block-shaped double-sided tape product. A gear 13 is fixed on one side of the separating roller 10, the squeezing roller 11 and the cutting roller 12. The gear 13 on the separating roller 10 is respectively engaged with the gear 13 on the squeezing roller 11 and the cutting roller 12.

[0027] The die-cutting cylinder 4 and the pressure-cutting roller 5 are both fixedly provided with gear 2 14 on the side away from the first motor 6, and are meshed with each other. The pressure-cutting roller 5 is fixedly provided with pulley 15 on the side away from gear 2 14, and the cutting roller 12 is fixedly provided with pulley 2 16 on the side away from gear 1 13. Belt 17 is provided on pulley 15 and pulley 2 16.

[0028] like Figure 2 As described above, when the first motor 6 drives the die-cutting cylinder 4 to rotate counterclockwise, the die-cutting cylinder 4 drives the pressing roller 5 to rotate clockwise through the two meshing gears 2 14, and the pressing roller 5 drives the cutting roller 12 to rotate clockwise through the pulley 15, the pulley 2 16 and the belt 17. The cutting roller 12 causes the separating roller 10 to rotate counterclockwise through the two gears 13. When the separating roller 10 rotates counterclockwise, the squeezing roller 11 is caused to rotate clockwise through the gear 13, so that the strip of double-sided tape cut by the die-cutting cylinder 4 is attached to the top of the separating roller 10, and then passes between the separating roller 10 and the squeezing roller 11, and finally passes between the separating roller 10 and the cutting roller 12, so that it is cut into block-shaped double-sided tape products by the short blade on the cutting roller 12. Example

[0029] The block mechanism is provided with a collecting mechanism for collecting block double-sided tape. The collecting mechanism includes a plurality of air channels 18 opened in an annular array on the separation roller 10 and the cutting roller 12. A plurality of air holes 19 communicating with the air channels 18 are opened on the surface of the separation roller 10 and the cutting roller 12. One of the third fixed plates 9 is provided with an arc-shaped suction groove 20 and an arc-shaped blowing groove 21 near the separation roller 10, and a circular blowing groove 22 is provided near the cutting roller 12. 21 is connected to the circular blowing groove 22 through the vent 23, the arc-shaped air suction groove 20 and the arc-shaped air blowing groove 21 are connected to the air channel 18 opened on the separation roller 10, and the circular air blowing groove 22 is connected to the air channel 18 opened on the cutting roller 12. The third fixed plate 9 here fits with the side of the separation roller 10 and the cutting roller 12 but is not fixedly connected, thereby increasing the air tightness between the arc-shaped air suction groove 20 and the arc-shaped air blowing groove 21 and the separation roller 10, and between the circular air blowing groove 22 and the cutting roller 12.

[0030] An air suction pump 24 and an air blowing pump 25 are fixedly provided on the third fixed plate 9 respectively. The air suction pump 24 is connected to the arc-shaped air suction groove 20 through a connecting pipe 26, and the air blowing pump 25 is connected to the arc-shaped air blowing groove 21 through a connecting pipe 26. A collecting groove 27 is fixedly provided between the two third fixed plates 9. An outlet 28 connected to the collecting groove 27 is provided on the operating table 1. A plurality of baffles 48 are fixedly provided above the collecting groove 27. The baffles 48 can separate the multiple strips of double-sided adhesive tape coming out of the smoothing roller 44 and then wind them on the separating roller 10.

[0031] When the suction pump 24 is working, negative pressure is generated through the arc-shaped suction groove 20 and the air channel 18 on the separation roller 10 connected to the arc-shaped suction groove 20, and the strip double-sided tape will be adsorbed on the separation roller 10 through the air hole 19. When the blowing pump 25 is working, air is blown to the air channel 18 on the separation roller 10 connected to the arc-shaped blowing groove 21 through the arc-shaped blowing groove 21 to generate high-pressure gas, which is finally discharged through the air hole 19, thereby separating the block double-sided tape on the separation roller 10. At the same time, air is blown to the air channel 18 on the cutting roller 12 through the circular blowing groove 22 to generate high-pressure gas, which is finally discharged through the air hole 19, thereby preventing the block double-sided tape falling from the separation roller 10 from falling onto the cutting roller 12. Example

[0032] The stripping mechanism is provided with a glue removal mechanism for removing glue from the die-cutting knife cylinder 4. The glue removal mechanism includes a movable groove 29 provided on the two first fixed plates 3. A movable rod 30 is fixedly provided in the movable groove 29. A scraper 31 is slidably sleeved on the movable rod 30. The scraper 31 is provided with a plurality of grooves corresponding to the annular blades on the die-cutting knife cylinder 4. The movable rod 30 is sleeved with a spring 32 under the scraper 31. When the die-cutting knife cylinder 4 is rotating for cutting, the scraper 31 can scrape off the glue adhered to the annular blades on the die-cutting knife cylinder 4, so as not to affect the subsequent cutting.

[0033] Working principle: First, the double-sided tape with a base tape on one side is wound on the double-sided tape unwinding roller 8, and the other base tape is wound on the base tape unwinding roller 33. Then, they pass through the tightening roller 38 respectively, and then pass through the middle of the two pressing rollers 41. After being cut between the die-cutting cylinder 4 and the pressing roller 5, the strip of double-sided tape formed passes through the middle of the two smoothing rollers 44. The cut waste is wound on the winding roller 46. After the strip of double-sided tape passes through the middle of the two smoothing rollers 44 and passes through the middle of the adjacent baffles 48, it is placed on the separation roller 10.

[0034] Then the first motor 6, the second motor 47, the suction pump 24 and the blowing pump 25 are started at the same time. The suction pump 24 generates negative pressure in the arc-shaped suction groove 20 and the air channel 18 connected to the arc-shaped suction groove 20 on the separation roller 10 through the connecting pipe 26. The strip of double-sided tape will be adsorbed on the separation roller 10 through the air hole 19. Then the first motor 6 rotates, driving the die-cutting cylinder 4 and the pressure-cutting roller 5 to rotate. The pressure-cutting roller 5 drives the cutting roller 12 to rotate together through pulley 15, pulley 2 16 and belt 17. When the cutting roller 12 rotates, it drives the separation roller 10 and the squeezing roller 11 to rotate together through gear 13, so that the entire double-sided tape can move continuously.

[0035] The double-sided tape with a bottom tape on one side and the other bottom tape are pressed together by two pressing rollers 41 during movement to form a double-sided tape with bottom tapes on both sides. The double-sided tape is cut into strips of double-sided tape when passing through the die-cutting cylinder 4 and the pressing roller 5 during movement, and the excess waste is wound up by the winding roller 46 driven by the second motor 47. The cut strips of double-sided tape are adsorbed by the air holes 19 on the separating roller 10 after reaching the separating roller 10, and rotate with the separating roller 10, and then are squeezed by the squeezing roller 11 and then moved to the cutting roller 12, and are cut into blocks of double-sided tape by the short blade on the cutting roller 12. At this time, the blocks of double-sided tape on the separating roller 10 are still The double-sided tape is adsorbed on the separating roller 10, and the separating roller 10 continues to rotate until the air channel 18 is connected to the arc-shaped blowing groove 21. The blowing pump 25 blows air to the arc-shaped blowing groove 21 and the circular blowing groove 22 through the connecting pipe 26. The arc-shaped blowing groove 21 blows air to the air channel 18 on the separating roller 10, and blows down the block double-sided tape adsorbed thereon through the air hole 19. At the same time, the circular blowing groove 22 blows air to the air channel 18 on the cutting roller 12, and finally discharges it through the air hole 19 to prevent the block double-sided tape falling from the separating roller 10 from falling onto the cutting roller 12. The cut block double-sided tape products finally fall into the collecting tank 27 and are finally discharged from the discharge port 28.
