[0017] The present application is further described in detail below in conjunction with the accompanying drawings.

[0018] The embodiments of the present application disclose a non-stop material changing device, a die-cutting device, and a non-stop material changing method.

[0019] Reference Figure 1 and Figure 2 The die-cutting device includes a non-stop material changing device for continuously providing material strips to the die-cutting mechanism. The non-stop material changing device includes a frame 1, on which are mounted two feeding mechanisms 2 which are mutually standby. A docking roller group 3, a pressing roller group 4 and a material strip deviation corrector 5 are sequentially arranged between the two feeding mechanisms 2 along the traveling direction of the material strips.

[0020] The frame 1 includes a base 11 and an equipment mounting platform 12 installed on the base 11. The feeding mechanism 2, the docking roller group 3, the laminating roller group 4 and the material belt deviation corrector 5 are all installed on the equipment mounting platform 12. The equipment mounting platform 12 is hollow inside.

[0021] The two feeding mechanisms 2 are mirror images of each other, and this embodiment is described by taking one of the feeding mechanisms 2 as an example. The feeding mechanism 2 includes a feeding body 21, a feeding roller shaft 22, and a guide roller group 23 for guiding the material belt on the feeding roller shaft 22 to the feeding body 21. The feeding body 21 is fixedly mounted on the equipment mounting platform 12, and the feeding roller shaft 22 and the guide roller group 23 are both rotatably mounted on the equipment mounting platform 12.

[0022] Reference Figure 3 The feeder body 21 itself has a feeding chamber 211 through which the feed belt passes. The bottom surface of the feeding chamber 211 is set as a cutting table. The feeder body 21 is vertically slidably mounted with a cutting knife 24 in the feeding chamber 211. A cutting cylinder 25 is mounted on the top of the feeder body 21. The cutting cylinder 25 is in transmission connection with the cutting knife 24. When the cutting cylinder 25 is working, it drives the cutting knife 24 to slide vertically in the feeding chamber 211. The cutting knife 24 cooperates with the bottom surface of the feeding chamber 211 to cut the material belt in the feeding chamber 211. The cutting cylinder 25 and the cutting knife 24 constitute the material belt cutting function component of the feeder body 21.

[0023] The feeder body 21 is also provided with a feed roller set 26 in the feed chamber 211. The feed roller set 26 consists of two feed rollers, which are installed in the feeder body 21 to rotate up and down, and a gap is left between the two feed rollers for clamping the conveyor belt. A feed motor is provided on one side of the feeder body 21 to provide power for the feed rollers.

[0024] The docking roller group 3 is composed of two docking rollers. Two docking bases 13 are horizontally slidably installed on the equipment installation platform 12. The two docking rollers of the docking roller group 3 are respectively rotatably installed on the two docking bases 13. Two docking cylinders are symmetrically arranged in the equipment installation platform 12. The output ends of the two docking cylinders are respectively connected to a docking base 13. The docking base 13 and the docking rollers are driven by the docking cylinders to perform horizontal translation movement on the equipment installation platform 12. When the two docking bases 13 move toward each other, the two docking rollers are abutted together; when the two docking bases 13 move away from each other, the two docking rollers are separated.

[0025] The laminating roller set 4 is composed of two laminating rollers, and two laminating bases 14 are fixedly installed on the equipment mounting platform 12, and the two laminating rollers are rotatably installed on the two laminating bases 14. The two laminating rollers are pressed together to perform laminating processing on the material strip passing through the laminating roller set 4.

[0026] The material strip that flows from the lamination roller set 4 to the strip deflection corrector 5 can be guided by the deflection corrector to keep the strip conveying consistent, thereby ensuring the stability of the strip conveying and continuously and stably providing the strip for the next process.

[0027] Reference Figure 1 The process of the non-stop material changing device continuously providing material belts for the die-cutting device is as follows: in the two feeding mechanisms 2 of the non-stop material changing device, which are mutually dependent, material trays are installed on the two feeding roller shafts 22. The material belt of the first feeding mechanism 2 is guided by the guide roller group 23, and the material belt enters the feeding body 21, and then passes through the docking roller group 3, the pressing roller group 4 and the material belt deviation corrector 5 in turn, and finally flows to the next process equipment and continuously feeds the next process equipment. At this time, the roller shafts of the docking roller group 3 themselves are in a back-to-back state, that is, there is a gap between the docking roller groups 3 for the material belt to pass through.

[0028] The material belt of the second feeding mechanism 2 is taped at the connection point. When the material belt of the first feeding mechanism 2 is about to be used up and needs to be replaced, the material belt cutting function component of the first feeding mechanism 2 cuts the material belt, and the feeding roller group 26 of the second feeding mechanism 2 temporarily conveys the second material belt. The tail of the first group of material belts and the head of the second group of material belts meet at the docking roller group 3. The docking roller group 3 moves towards each other under the action of the docking cylinder, and the tail of the first group of material belts and the head of the second group of material belts are pre-bonded together with the tape. Then the docking roller group 3 moves away from each other, and the material belts are pressed by the pressing roller group 4 to achieve stable connection and replacement of the two groups of material belts. In this reciprocating manner, only a small proportion of the time of the original manual joint is required to complete the non-stop material replacement action of the die-cutting device, which greatly improves production efficiency, reduces operation time, and effectively increases the market competitiveness of our products.

[0029] In this embodiment, the opening and closing of each driving cylinder and transmission roller can be controlled by sensors in conjunction with PLC.

[0030] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
