A slitting cutter and an automatic glue grinding device for the same

Abstract

This invention relates to a slitting blade and an automatic adhesive grinding device for slitting. The slitting blade includes a blade body, which is a circle with a thickness. The edge of the blade body is a conical blade wall, and the blade wall is frosted by arranging a plurality of raised dots on the blade wall. Compared with the prior art, this invention frosts the blade wall of the slitting blade and designs raised dots on it. This allows the slitting blade to directly grind the cut surface when cutting into roll material (double-sided tape) during high-speed rotation, preventing adhesive from overflowing from the cut edge.

Description

Technical Field

[0001] This invention relates to the field of die-cutting technology, specifically to a slitting tool and an automatic slitting and grinding device. Background Technology

[0002] Die cutting is a method of high-precision stamping of existing materials into a predetermined shape. Before stamping, it is often necessary to cut the original material (e.g., 1200mm*200m) into smaller pieces (e.g., 60mm*200m).

[0003] Currently, the most common material to be slit is double-sided tape without a substrate (pure adhesive coated on release paper to form a roll), commonly known as substrate-free double-sided tape. During slitting of substrate-free double-sided tape, the adhesive has very high fluidity on the release paper, causing it to overflow before stamping. Due to the roll shape, this overflowing adhesive further connects, ultimately leading to glue bridging during the unfolding process. This glue bridging results in wrinkles, insufficient adhesive, and other abnormalities after stamping, leading to product defects and significant losses for the company. Summary of the Invention

[0004] The purpose of this invention is to provide a slitting tool and an automatic slitting and gluing device to solve the above problems. By improving the structure of the slitting tool, the cutting surface can be polished at the same time when the material is slitting, so as to avoid the problem of double-sided adhesive overflow during the long-term storage of the material after slitting.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A slitting tool includes a slitting blade body, the slitting blade body being a circle with thickness, the edge of the slitting blade body being a tapered blade wall, and the blade wall being frosted.

[0007] Furthermore, the frosting process involves arranging several raised structures on the blade edge wall.

[0008] Furthermore, the protrusions are arranged in an array covering the blade wall.

[0009] Furthermore, the particle size of the bump structure is 0.1-0.5 mm.

[0010] Furthermore, the blade wall is smooth in the first 1 / 3 of the area from the outermost edge of the slitting blade body, and the remaining area is frosted.

[0011] Furthermore, the included angle of the tapered edge of the slitting blade body is 15-30°.

[0012] Furthermore, the diameter of the slitting blade body is 15-30cm, the thickness is 2-5mm, and the width of the blade wall is 1-10mm.

[0013] An automatic slitting and gluing device is provided, equipped with the aforementioned slitting blade. The device includes a frame, which is provided with a slitting blade fixing mechanism for mounting the slitting blade, a roll material fixing mechanism for mounting the roll material to be slitted, and a control mechanism. The slitting blade fixing mechanism includes a slitting blade mounting bracket, on which the slitting blade is mounted and driven by a drive component. A track is provided on the frame, and the slitting blade mounting bracket is slidably mounted on the track. The roll material fixing mechanism includes a fixed clamp at one end of the frame and an auxiliary clamp at the other end. A roll material shaft for placing the roll material to be slitted is provided between the fixed clamp and the auxiliary clamp, and the roll material shaft is driven by the drive component. The control mechanism includes a manual control console, a touchscreen parameter controller, a power switch, and an emergency stop button.

[0014] Furthermore, the fixed clamp is a pneumatic clamp, and the driving component is a motor.

[0015] Because the cutting blades currently used have smooth surfaces on the blade edges, they cannot "polish" the cut surface of the double-sided adhesive roll when cutting into it. As a result, after being left for a long time, the double-sided adhesive will overflow from the cut point, causing the overflowing adhesive to stick together. This will eventually lead to adhesive sticking when unfolding the roll for the next process.

[0016] To solve this technical problem, this invention involves frosting the blade edge of the slitting blade and designing raised dots on it. This allows the slitting blade to directly grind the cut surface when cutting into the roll material (double-sided tape) during high-speed rotation, similar to a grinding wheel. The smooth blade, due to the adhesive's properties, wraps the roll material around the smooth blade edge. Furthermore, the frosted blade edge immediately grinds the cut surface after cutting, ensuring that the release paper or film of the double-sided tape is slightly higher than the area where the tape is present, further preventing adhesive overflow after cutting.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example

[0023] Currently, during material slitting, because the material is a type of double-sided adhesive without a substrate (pure glue coated on release paper to form a roll), commonly known as substrate-free double-sided adhesive, the glue has a very high fluidity on the release paper. This causes the glue to overflow after slitting and before stamping, resulting in the overflowing glue connecting together. This eventually leads to glue bridging when unfolding for the next process, ultimately causing abnormalities such as glue wrinkles and glue shortages in the final stamped product.

[0024] To solve this technical problem, the present invention provides a slitting tool 2, such as... Figure 1 , 2 The slitting blade body is circular with a diameter of 22 cm and a thickness of 5 mm. The edge of the slitting blade body has a conical blade wall 21 with a conical angle of 15° and a width of 8 mm. In this embodiment, the blade wall is sanded. Specifically, the sanding process involves arranging several raised structures on the blade wall. These raised structures can be made of abrasive particles, arranged in an array covering the blade wall. The particle size of the raised structures is 0.5 mm, and the raised particles are specifically positioned in the last two-thirds of the area from the outermost edge of the slitting blade body.

[0025] The aforementioned slitting blades are specifically applied to an automatic glue-grinding slitting device, such as... Figure 3 The device includes a frame 1, which is equipped with a slitting blade fixing mechanism for mounting the slitting blade 2, a roll material fixing mechanism for mounting the roll material to be slitted, and a control mechanism. The slitting blade fixing mechanism includes a slitting blade fixing frame 11, on which the slitting blade 1 is mounted and connected to a drive component, which is a motor. The frame is provided with a rail 12, on which the slitting blade fixing frame 11 is slidably mounted. The roll material fixing mechanism includes a fixing clamp 3 at one end of the frame 1 and an auxiliary clamp 5 at the other end. A roll material shaft 4 for placing the roll material to be slitted is provided between the fixing clamp 3 and the auxiliary clamp 5. The roll material shaft 4 is connected to the drive component, which is a motor. The control mechanism includes a manual control console 6, a touch screen parameter controller 7, a power switch 8, and an emergency stop button 9. The fixing clamp is a pneumatic clamp.

[0026] In practical use, Figure 4 The roll material to be cut shown is installed on Figure 3On the roll spool 4, the manual control console 6 is used for operation and control. The auxiliary chuck 7 is opened, and the entire roll 10 to be cut is placed on the roll spool 4. One end of the roll 10 to be cut rests directly against the fixed chuck 3. Using the button on the manual control console 6, the fixed chuck 3 is inflated to further fix the roll 10 to be cut. Then, the relevant parameters are set using the touch screen parameter controller 7, and the cutting begins. During cutting, the roll spool 4 is connected to the motor and rotates 360 degrees under the drive of the motor. The cutting blade 2 also rotates 360 degrees under the drive of the motor. The cutting blade fixing frame 11 moves along the track 12, which is parallel to the axis of the roll spool 4. After moving to the set position, the cutting blade 1 cuts the roll directly. At the same time, the cut surface is polished. After polishing, the cut edge is finished, and the glue no longer overflows.

It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
