Description

Technical Field

[0001] The invention relates to the field of processing die-cut parts, and in particular to a production system for hollow special-shaped double-sided adhesive die-cut parts. Background Art

[0002] The hollow special-shaped double-sided adhesive die-cut parts with narrow outer frames have a large area without adhesive inside, such as Figure 9-10 As shown in the figure, although the double-sided adhesive is partially hollowed out, the handle release film is a whole piece without hollowing out. In other words, the internal waste of the double-sided adhesive hollow pattern will not be discharged together with the handle release film.

[0003] During the waste discharge process, due to the strong adhesion between the double-sided adhesive and the handle release film, when the internal waste is discharged, it often brings up the adhesive of the hollow shaped double-sided adhesive product, causing the hollow die-cut product to shift, resulting in a decrease in the quality of the final product. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a production system for hollow special-shaped double-sided adhesive die-cut parts with more efficient waste discharge and reduced product defect rate.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A production system for hollow special-shaped double-sided adhesive die-cut parts, the system comprises a first punch pre-laminating unit, a first punch die-cutting unit, a second punch pre-laminating unit, a second punch die-cutting machine, a second punch waste discharge unit, a third punch die-cutting unit and a die-cut part receiving unit;

[0007] The pre-punching laminating unit comprises a handle release film unloading roller, a low-viscosity protective film unloading roller and a low-viscosity bottom film unloading roller, wherein the handle release film unloading roller unwinds the handle release film, the low-viscosity protective film unloading roller unwinds the low-viscosity protective film, and the low-viscosity bottom film unloading roller unwinds the low-viscosity bottom film. After passing through the pre-punching laminating unit, the low-viscosity protective film and the low-viscosity bottom film are respectively laminated on the upper and lower sides of the handle release film; after being punched and cut by a punching and die-cutting unit, a primary material strip is formed, wherein the waste material of the low-viscosity protective film after die-cutting is discharged, and the remaining low-viscosity protective film The sheet continues to be pasted on the primary material strip; the double-sided adhesive and the auxiliary release film are pasted on the primary material strip by the second punch front laminating unit; after being punched and cut by the second punch die-cutting machine, a secondary material strip is formed; the second punch waste discharge unit discharges the auxiliary release film after the auxiliary release film is die-cut, and then discharges other waste materials to form a tertiary material strip; after being punched and cut by the third punch die-cutting unit, a fourth material strip is formed, and the frame waste on the fourth material strip is discharged; the shipping release film is pasted on the fourth material strip by the receiving unit, and the bottom material is discharged to form a hollow special-shaped double-sided adhesive die-cut piece, which is then rolled up.

[0008] Furthermore, the die-cutting unit includes a die-cutting machine and a first row of waste rollers. The die-cutting machine is provided with an etching die, on which a blade a and a blade b are provided. The pattern die-cut by blade a matches the pattern of the handle release film on the double-sided adhesive die-cut piece, and the pattern die-cut by blade b matches the low-viscosity protective film. The first row of waste rollers discharges waste materials after the low-viscosity protective film is die-cut.

[0009] Furthermore, the distance between the edge of the low-viscosity protective film and the edge of the inner frame pattern of the double-sided adhesive die-cut piece is 0.2-1mm, the area of ​​the low-viscosity protective film is 90-95% of the area of ​​the inner frame pattern of the double-sided adhesive die-cut piece, and the punching layers of the blade a include a low-viscosity protective film and a handle release film in sequence; the punching layers of the blade b include a low-viscosity protective film.

[0010] Furthermore, the second punching front laminating unit comprises a double-sided adhesive feeding roller and an auxiliary release film feeding roller.

[0011] The double-sided adhesive unwinding roller unwinds the double-sided adhesive, and the auxiliary release film unwinding roller unwinds the auxiliary release film, and the double-sided adhesive and the auxiliary release film are sequentially attached to the primary material belt.

[0012] Furthermore, the two-punch die-cutting machine is provided with an etching die, on which a blade c is provided, the pattern die-cut by blade c matches the inner frame pattern of the hollow special-shaped double-sided adhesive die-cut piece, the distance between the edge of the pattern die-cut by blade b and the edge of the pattern die-cut by blade c is 0.2-1mm, the area of ​​the pattern die-cut by blade b is 90-95% of the area of ​​the pattern die-cut by blade c, and the pattern die-cut by blade b is similar to the pattern die-cut by blade c, but the area is slightly smaller.

[0013] Since the bonding force between the low-viscosity protective film and the double-sided adhesive is lower than that between the double-sided adhesive and the handle release film, and since the pattern frame die-cut by blade b is 0.2-1mm away from the pattern frame die-cut by blade c, most of the double-sided adhesive is attached to the low-viscosity protective film, and only a small part is attached to the handle release film. At this time, the force required to tear off the waste inside the double-sided adhesive hollow pattern is smaller, and waste removal is easier, and it is less likely to affect the glue of the double-sided adhesive product, so it will not cause the displacement of the hollow die-cut product. At the same time, since the low-viscosity protective film itself has a certain thickness, the double-sided adhesive at the internal pattern position is more prominent than the external double-sided adhesive, and the auxiliary waste removal film is easier to contact the glue area that needs to be discharged, which is conducive to waste discharge.

[0014] It should be pointed out that the reason why the distance between the edge of the pattern die-cut by blade b and the edge of the pattern die-cut by blade c is 0.2-1mm is because the blade will produce a certain tolerance during processing. In order to avoid the pattern area die-cut by blade b being larger than that of blade c, the distance between the edge of the pattern die-cut by blade b and the edge of the pattern die-cut by blade c is simply 0.2-1mm during design to avoid the pattern area die-cut by blade b being larger than that of blade c, which affects product quality.

[0015] Furthermore, the punching layers of the blade c include an auxiliary release film, a double-sided adhesive tape and a low-viscosity protective film.

[0016] Furthermore, the two-wash waste discharge unit includes a waste discharge tape discharge roller, a second waste discharge roller, an auxiliary waste discharge film discharge roller and a third waste discharge roller.

[0017] The waste discharge tape unwinding roller unwinds the waste discharge tape, the auxiliary waste discharge film unwinding roller unwinds the auxiliary waste discharge film, the waste discharge tape sticks to the auxiliary release sheet formed after the auxiliary release film is die-cut, and then is reeled and discharged through the second row of waste rollers, the auxiliary waste discharge film is adhered to the secondary material tape, and the auxiliary waste discharge film, the waste remaining after the auxiliary release film is punched and cut, and the waste inside the double-sided adhesive hollow pattern are discharged through the third row of waste rollers.

[0018] Furthermore, the three-punch die-cutting unit comprises a second auxiliary release film discharge roller, a three-punch die-cutting machine and a fourth row of waste rollers.

[0019] The second auxiliary release film is discharged from the second auxiliary release film discharge roller, and the second auxiliary release film is attached to the three-level material belt. The three-punch die-cutting machine is provided with an etching die, and the etching die is provided with a blade d, and the blade d matches the outer frame pattern of the hollow special-shaped double-sided adhesive die-cutting piece. The fourth row of waste rollers rolls up and discharges the frame waste formed by the three-punch die-cutting machine and the second auxiliary release film.

[0020] Furthermore, the punching layers of the blade d include, in sequence, a second auxiliary release film, a double-sided adhesive tape, a low-viscosity protective film and a handle release film.

[0021] Furthermore, the die-cutting piece receiving unit comprises a delivery release film unloading roller, a fifth row of waste rollers and a die-cutting piece receiving roller;

[0022] The shipping release film unwinding roller unwinds the shipping release film, which is attached to the four-level material belt. The fifth row of waste rollers rolls up and discharges the remaining low-viscosity base film and the handle release film punched by the three-punch die-cutting unit. The die-cutting piece receiving roller rolls up the hollow special-shaped double-sided adhesive die-cut pieces.

[0023] Furthermore, the material of the low-viscosity protective film includes PE; the material of the auxiliary waste discharge film includes PET.

[0024] In general, the operation of the production system of hollow shaped double-sided adhesive die-cut parts includes the following steps:

[0025] (1) Laminating a low-viscosity protective film and a low-viscosity bottom film on the upper and lower sides of the handle release film, respectively, and punching and cutting the film with a punching and die-cutting machine to form a primary material strip;

[0026] (2) The waste material after the low-viscosity protective film is die-cut is discharged, and the formed low-viscosity protective film sheet continues to be adhered to the primary material belt;

[0027] (3) sequentially laminating the double-sided adhesive tape and the auxiliary release film on the primary material strip, and passing through a secondary die-cutting machine to form a secondary material strip;

[0028] (4) using adhesive tape to discharge the auxiliary release film after die-cutting, and then laminating the auxiliary waste discharge film on the secondary material belt, and then discharging the waste material to form a tertiary material belt;

[0029] (5) laminating the second auxiliary release film on the third-level material strip, and punching it with a three-punch die-cutting machine to form a fourth-level material strip;

[0030] (6) The frame waste on the fourth-level material belt is discharged, and then the shipping release film is attached to the fourth-level material belt, and the bottom material is discharged to form a hollow special-shaped double-sided adhesive die-cut part.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] (1) A blade b is provided on a die-cutting machine, and a low-viscosity protective film is punched out and continuously pasted on the primary material strip as a medium between the double-sided adhesive tape and the handle release film. Since the distance between the edge of the pattern cut out by blade b and the edge of the pattern cut out by blade c is 0.2-1 mm, and the area of ​​the pattern cut out by blade b is 90-95% of the area of ​​the pattern cut out by blade c, most of the double-sided adhesive tape is adhered to the low-viscosity protective film, and only a small part is adhered to the handle release film. At this time, the force required to tear off the waste material inside the hollow pattern of the double-sided adhesive tape is smaller, making it easier to discharge the waste material inside the double-sided adhesive tape, so that the displacement of the hollow die-cut product will not be caused, and the double-sided adhesive of the product at the edge of the hollow pattern will not be affected;

[0033] (2) The low-viscosity protective film of the present invention has a certain thickness. The double-sided adhesive tape at the inner pattern position is more prominent than the outer double-sided adhesive tape. The auxiliary waste discharge film is more likely to contact the adhesive area where waste needs to be discharged, which is beneficial to waste discharge.

[0034] (3) The improved production method will not cause the double-sided adhesive tape of the product to shift when discharging the double-sided adhesive tape waste, thereby reducing the dimensional defects caused by the displacement of the double-sided adhesive tape. The product dimensional defect rate has dropped from 60% before the improvement to 1% after the improvement. BRIEF DESCRIPTION OF THE DRAWINGS

After passing through the pre-punch laminating unit, the low-viscosity protective film 1 and the low-viscosity bottom film 3 are respectively laminated on the upper and lower sides of the handle release film 2; after being punched and cut by the first punch die-cutting unit, a primary material strip is formed, wherein the low-viscosity The waste material after the protective film 1 is die-cut is discharged, and the remaining low-viscosity protective film sheet 11 continues to be pasted on the primary material strip; the double-sided adhesive tape 51 and the auxiliary release film 52 are pasted on the primary material strip by the second punch pre-lamination unit; after being punched by the second punch die-cutting machine 6, a secondary material strip is formed; the second punch waste discharge unit discharges the auxiliary release film 53 after the auxiliary release film 52 is die-cut, and then discharges other waste materials to form a tertiary material strip; after being punched by the third punch die-cutting unit, a fourth-level material strip is formed, and the frame waste material on the fourth-level material strip is discharged; the shipping release film 10 is pasted on the fourth-level material strip by the receiving unit, and the base material is discharged to form a hollow special-shaped double-sided adhesive die-cut piece, which is then rolled up.

[0049] A die-cutting unit comprises a die-cutting machine 4 and a first row of waste rollers. The die-cutting machine 4 is provided with an etching die, and the etching die is provided with a blade a and a blade b. Figure 5 The pattern cut by blade a matches the pattern of the handle release film 2 on the double-sided adhesive die-cut piece, and the pattern cut by blade b matches the low-viscosity protective film 11. The first row of waste rollers discharges the waste after the low-viscosity protective film 1 is die-cut. The distance between the edge of the low-viscosity protective film 11 and the edge of the inner frame pattern of the double-sided adhesive die-cut piece is 0.2-1mm, and the area of ​​the low-viscosity protective film 11 is 90-95% of the area of ​​the inner frame pattern of the double-sided adhesive die-cut piece.

At the same time, since the low-viscosity protective film itself has a certain thickness, the double-sided adhesive at the internal pattern position is more prominent than the external double-sided adhesive, and the auxiliary waste removal film is easier to contact the glue area that needs to be discharged, which is conducive to waste discharge.

[0052] It should be pointed out that the reason why the distance between the edge of the pattern cut by blade b and the edge of the pattern cut by blade c is 0.2-1mm is because the blade will have a certain tolerance during processing. In order to avoid the pattern area cut by blade b being larger than that of blade c, the distance between the edge of the pattern cut by blade b and the edge of the pattern cut by blade c is simply 0.2-1mm during design to avoid the pattern area cut by blade b being larger than that of blade c, which affects the product quality.
