Detailed Implementation

[0016] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0017] like Figures 1 to 3 As shown, a twill refracting embossing device for packaging materials includes a processing platform 1, a support body disposed on both sides of the conveying direction of the processing platform 1, and an embossing device 4 disposed in the middle of the processing platform 1. The two ends of the embossing device 4 are connected to the support body. The embossing device 4 includes a printing plate roller 41 and an impression roller 42. The support body is provided with a first driving mechanism 5 that drives the printing plate roller 41 to move toward the impression roller 42, and a second driving mechanism 6 that drives the impression roller 42 to move toward the printing plate roller 41. The processing platform 1 is provided with an auxiliary clamping device 7 at the upper station of the embossing device 4. The auxiliary clamping device 7 consists of at least two auxiliary clamping rollers, and the contact surface between two adjacent auxiliary clamping rollers is aligned with the top surface of the embossing roller 42.

[0018] In one technical solution of the embossing device 4 of this utility model, the roller surface of the embossing roller 42 is covered with a rubber layer, and the roller surface of the printing plate roller 41 adopts a grooved prism-shaped microprism structure, arranged in a microprism matrix, and locally adopts a staggered arrangement to form a unique refraction and reflection path. Furthermore, the roller surface of the printing plate roller 41 can be divided into different functional areas according to the packaging paper requirements and refractive effect requirements. The main refractive area adopts a dense arrangement of microprisms and is located in the main display part, such as the front of the product and the cover. The strong refractive effect highlights the product features, attracts attention, and enhances visual appeal. For example, luxury packaging can show high-end quality. The auxiliary area is set up with a text decoration area, using sparse or different shaped textures to display brand and other information.

[0019] In the technical solution of the processing platform 1 of this utility model, the embossing device 4 and the auxiliary clamping device 7 are provided in the middle of the processing platform 1, and a material conveying channel 13 is provided along the length direction of the processing platform 1. During the process of material conveying through the material conveying channel 13, the material is clamped by the auxiliary clamping device 7 in advance and enters the embossing device 4 horizontally, so that the embossing device 4 can perform stable embossing processing on the material.

[0020] It should be noted that the outer side of the processing platform 1 is provided with a first rotating motor 11 that drives the printing plate roller 41 to rotate, and a second rotating motor 12 that drives the impression roller 42 to rotate. The first rotating motor 11 and the second rotating motor 12 drive the printing plate roller 41 and the impression roller 42 to rotate in opposite directions, respectively. When the printing plate roller 41 rotates clockwise, the impression roller 42 rotates counterclockwise, thereby "biting" the material between the two into the roller gap for embossing and achieving smooth conveying.

[0021] In the technical solution of the support body of this utility model, the support body includes a first support 2 and a second support 3 arranged in pairs, and the second support 3 and the first support 2 are arranged sequentially along the material conveying direction. There are two first supports 2, which are respectively arranged on both sides of the processing platform 1. The first drive mechanism 5 is arranged on the top of the first support 2. There are two second supports 3, which are respectively arranged on both sides of the processing platform 1.

[0022] It should be noted that the first support 2 is provided with an embossing device 4, the second support 3 is provided with an auxiliary clamping device 7, and the first driving mechanism 5 drives the printing plate roller 41 to move toward or away from the printing roller 42, thereby adjusting the gap between the printing roller 42 and the printing plate roller 41 to make it suitable for materials of different thicknesses. Specifically, in the above scheme, a first strip groove 21 is provided along the length direction of the first support 2, the end of the printing plate roller 41 passes through the first strip groove 21 and is connected to the output end of the first drive mechanism 5, and the end of the impression roller 42 passes through the first strip groove 21 and is connected to the output end of the second drive mechanism 6. The first drive device and the second drive mechanism 6 are connected.

[0023] Furthermore, in the above scheme, a second strip groove 31 is provided along the length direction of the second bracket 3, and the end of the auxiliary clamping roller passes through the second strip groove 31 and is connected to the output end of the second drive mechanism 6.

[0024] Furthermore, in the above scheme, the second driving mechanism 6 includes a driving cylinder 61 and a connector 62 disposed at the output end of the driving cylinder 61. The two ends of the connector 62 are respectively hinged to the impression roller 42 and the auxiliary clamping roller.

[0025] It should be noted that the horizontal height of the printing plate roller 41 can be adjusted by the first driving mechanism 5, thereby achieving the purpose of clamping the roller spacing according to different material thicknesses. The horizontal height of the impression roller 42 can be adjusted by the second driving mechanism 6. When the horizontal height of the impression roller 42 is adjusted, the horizontal height of the auxiliary clamping device 7 will be adjusted synchronously to keep the horizontal height of the auxiliary clamping device 7 consistent with the horizontal height of the impression roller 42, so that the material is horizontally fed into the embossing device 4. In one embodiment of this utility model, when the embossing device performs embossing on a material with a relatively hard material, the horizontal height of the embossing roller 42 is aligned and adapted with the material conveying height of the material conveying channel 13, so that the material can be directly fed into the embossing device 4 through the clamping device after being conveyed along the material conveying channel 13. In another embodiment of the present invention, when the embossing device is used to emboss softer materials, the horizontal height of the embossing roller 42 is higher than the horizontal height of the material conveying channel 13, and the material can be controlled to be in a taut conveying state under the adjustment of the second drive mechanism 6. Furthermore, in the above technical solution, the impression roller 42 and the printing plate roller 41 both slide back and forth along the first strip groove 21, the auxiliary clamping roller slides back and forth along the second strip groove 31, the impression roller 42 is connected to the end of the auxiliary clamping roller through the connector 62, and when the second drive mechanism 6 controls the connector 62 to lift or lower, the impression roller 42 and the auxiliary clamping roller are lifted or lowered synchronously.

[0026] Furthermore, in the above solution, the auxiliary clamping roller includes a first clamping roller 71 and a second clamping roller 72 arranged sequentially from top to bottom along the second strip groove 31. An elastic element 32 is provided between the top of the first strip groove 21 and the end of the first clamping roller 71. Under the action of the elastic element 32, the first clamping roller 71 abuts against the outer surface of the second clamping roller 72, which effectively solves the problem of smooth material conveying during the embossing process and avoids the decline in embossing quality caused by the shaking of the material during embossing.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
