Detailed Description

For making the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following drawings in the embodiments of the present invention will be combined, and the technical solution in the embodiments of the present invention is clearly and completely described, based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work are included in the protection scope of the present invention.

The utility model provides an indentation analogue means for testing cigarette case seals effect, including the clamp plate 1 that is used for extrudeing box piece 6, the thrust mechanism 2 that is used for driving clamp plate 1 up-and-down motion, and locate the indentation knife tackle 3 of clamp plate 1 bottom; when the pushing mechanism 2 drives the pressing plate 1 to move downwards, the pressing plate 1 extrudes the box sheet 6 placed below the pressing plate 1, the indentation knife group 3 simultaneously leaves a fracture 61 for tearing the seal 7 and a crease 62 for folding and forming the box sheet 6 on the box sheet 6, and the specific effects are shown in fig. 1, fig. 2 and fig. 3.

In the existing cigarette product, a cut is arranged on a cigarette case, but the cigarette case is not completely cut off when the cut is arranged, so that a part of the cut part is still connected with the cigarette case, the cut part is used as an opening part 63 of the cigarette case, a sealing paste 7 capable of being repeatedly pasted is covered on the opening part 63, and the covering range of the sealing paste 7 on the cigarette case exceeds the range of the opening part 63, so that when the sealing paste 7 is adhered with the cigarette case, the opening part 63 is fixed on the cigarette case, and the cigarette case is sealed. When the cigarette case needs to be opened, the sealing sticker 7 is torn from the cigarette case, and the sealing sticker 7 drives the opening part 63 to turn over on the cigarette case, so that the cut is opened, and a consumer can take cigarettes in the cigarette case through the cut. After the cigarette is taken, the seal 7 is stuck on the cigarette case, and the opening part 63 is driven to seal the cut.

Compare when seting up the incision on the cigarette case, cut off the cigarette case completely, it is sealed to the cigarette case directly through covering seal 7 in incision department, and this cigarette product seals the cigarette case simultaneously through seal 7 and the open part 63 that the cigarette case cut, and its sealed effect is better. However, this cigarette product also has a problem in that: when the seal 7 turns the opening portion 63 over the cigarette case, the remaining portion of the opening portion 63 connected to the cigarette case may be torn from the cigarette case, thereby affecting the use of the cigarette case. This is related to the design of the cut shape and the adhesive strength of the seal 7, so that in practical production, continuous tests are required to ensure the adhesion effect of the seal 7 on the cigarette case, and the remaining part of the opening part 63 connected with the cigarette case is not easily torn off from the cigarette case when the seal 7 is torn off, so as to achieve the best use effect of the cigarette product.

In actual production, the sealing label 7 is usually covered on the cigarette case after the cigarette case is formed, and at the moment, the tearing test of the sealing label 7 on the cigarette case wastes a large amount of production materials and labor resources, because once the test fails, the produced cigarette case can only be used as a waste product for treatment, and manpower and time spent in the processes of producing the cigarette case and forming the cigarette case are wasted. Therefore, before mass production, the cut and the cover seal 7 are usually simulated on the box sheet 6, and the test of tearing the seal 7 on the box sheet 6 for many times is performed to verify the sticking effect of the seal 7 and to prevent the opening part 63 from being torn from the cigarette case, so that the production material and labor resources are saved.

And this application has just designed a device that can simulate the incision shape that designs on box piece 6, and this device includes clamp plate 1, thrust mechanism 2 and indentation knife tackle 3, and indentation knife tackle 3 sets up in clamp plate 1 bottom, and thrust mechanism 2 is used for driving clamp plate 1 and reciprocates on vertical direction. When the box piece 6 is placed at the bottom of the pressing plate 1, the pressing plate 1 is driven to move downwards through the thrust mechanism 2, the pressing plate 1 is abutted to the box piece 6, the indentation knife group 3 at the bottom of the pressing plate 1 cuts off a fracture 61 on the box piece 6, and a part of the cut part is kept to be connected with a cigarette case, namely an opening part 63 of the cigarette case. When the test is carried out, the sealing paste 7 is only required to be covered on the opening part 63 arranged on the device, and the sealing paste 7 is repeatedly torn and stuck on the box piece 6 for many times, so that the sticking effect of the sealing paste 7 and the part which can not drive the opening part 63 to be connected with the cigarette case are torn from the cigarette case for verification, the tearing test of the sealing paste 7 is facilitated, and the production material and the labor resource are saved.

Since the opening part 63 of the cigarette case is usually arranged on the top of the cigarette case and extends from the top surface of the cigarette case to the front surface of the cigarette case in actual use, the cigarette in the cigarette case can be conveniently taken by a consumer through the cut, and the covering range of the sealing patch 7 on the cigarette case exceeds the range of the opening part 63, the sealing patch 7 generally extends from the back surface of the cigarette case to the front surface of the cigarette case across the top surface of the cigarette case. When the cigarette case is formed, in order to facilitate folding, the boundary between two adjacent side surfaces of the cigarette case is provided with a crease 62, and when the seal 7 spans the top surface of the cigarette case from the back surface of the cigarette case to the front surface of the cigarette case, the two crease 62 at the boundary between the top surface of the cigarette case and the back surface and the front surface of the cigarette case are covered, and the crease 62 possibly influences the sticking effect of the seal 7.
