Description

Technical Field

[0001] The invention belongs to the technical field of die cutting processing and relates to a device for quickly detecting the flatness of an etching knife. Background Art

[0002] like Figures 1-2 The double-sided adhesive product shown in the figure comprises a carrier tape 1, a product double-sided adhesive tape 2, and a product release film handle 3 arranged in sequence, and a silicone oil layer is also provided between the carrier tape 1 and the product double-sided adhesive tape 2. Figure 3 As shown, during the punching process of the product, if the die-cutting knife 5 punches too deep, the silicone oil layer 4 will be damaged, causing the product double-sided adhesive tape 2 to adhere to the carrier tape 1 or the product release film handle 3. Specifically, if the die-cutting knife of the imitation product is used to punch from the release film surface, the knife mark will remain on the product carrier tape. The silicone oil layer of the knife mark is damaged and no longer has the release ability, that is, the carrier tape has the knife mark, resulting in the product being unable to be removed from the carrier tape after being placed for 1 to 2 months. Figures 3-4 The dotted line in the middle indicates the marks made by the punching of the knife on the carrier tape. However, if you use the knife of the imitation product to punch from the adhesive surface, there will be knife marks left on the release film of the handle of the product. The silicone oil layer of this knife mark is damaged and no longer has the release ability. That is, there are knife marks on the handle of the product. However, if the cut is too deep, it will cut more than 30% of the thickness of the product release film and be cut off. The product can be removed from the carrier tape after being placed for 1 to 2 months. However, after being attached to the adhered object, when the handle is torn off, the double-sided adhesive of the product will be torn off along with the handle, or the handle cannot be removed. Figures 5-6 The dotted line in the middle shows the marks produced by tool punching on the product.

[0003] Damage to the silicone oil layer can lead to poor peeling, and this problem is particularly serious when using a roll-to-roll labeling machine, which can cause problems such as missing packaging and handles not being removed. Therefore, in order to ensure quality, it is necessary to ensure that there are no knife marks on the handles or carriers, or to ensure that the silicone oil layer is not damaged or the damage area is small if there are knife marks. Therefore, there are great requirements for the flatness of etching tools and die-cutting machines to avoid the problem of excessive punching depth. At present, the flatness can only be tested after the die-cutting machine is used to see whether it is flat. Sometimes the poor flatness of the tool affects the product quality.

[0039] like Figures 8 to 12 The device for quickly detecting the flatness of an etching knife shown in the figure comprises a mounting table 6 and a smooth round roller 7. The mounting table 6 is used to fix a flat knife with the blade facing upward; the smooth round roller 7 is arranged on the mounting table 6 for translation; the distance between the lower edge of the smooth round roller 7 and the mounting table 6 is equal to the sum of the thickness of the knife and the thickness of the bottom material strip; the bottom material strip is the material strip to be die-cut, excluding the layer to be punched.

[0040] When in use, the tool to be tested is fixed and placed flat on the mounting table 6 with the blade facing upwards, then the strips to be punched are stacked, and then the smooth round roller 7 is pushed over the strips to be punched, so as to use the self-weight of the smooth round roller 7 to cooperate with the tool for cutting, simulating the punching process. At this time, since the distance between the lower edge of the smooth round roller 7 and the mounting table 6 is equal to the sum of the thickness of the tool and the thickness of the bottom strip, ideally, only the strip above the bottom strip is cut; that is, if the test material is cut or the knife mark is too deep, the material will be damaged, and the film will be deformed at the too deep position; if the material is not cut at the cutting position, the blade of the tool at this position is deformed or the height is not enough. In this way, the flatness of the tool is detected.
