[0026] Please refer to Figures 1-9The utility model provides an embodiment: a kind of round die cutting machine, including discharging rack 1 and stacking rack 2, and die cutting assembly 3 is equipped between the discharging rack 1 and the stacking rack 2;The inside of the discharging rack 1 is equipped with storage assembly 10, and the storage assembly 10 includes first side plate 17 and second side plate 18;The side of the first side plate 17 is also equipped with first motor 13, and the first side plate 17 with the second side plate 18 is also equipped with transmission shaft 16 and first roller 12;The transmission shaft 16 is driven to work by the first motor 13 to promote the first roller 12 to move upwards or downwards between the first side plate 17 and the second side plate 18.
[0027] Because the inside of discharging rack 1 is equipped with storage assembly 10, when die cutting assembly 3 pauses, storage assembly 10 can be used to wind film material, specifically, when first motor 13 promotes transmission shaft 16 to rotate, in turn drives first roller 12 to move between two side plates to stretch film material, reduce film material accumulation;When die cutting assembly 3 works, first motor 13 reverses to promote first roller 12 to move upwards to release film material, to facilitate the smooth die cutting of film material, especially, the arrangement of storage assembly 10 makes the equipment can be suitable for the smooth conversion of film material from uniform motion to intermittent motion or step motion.
[0028] Further, the first side plate 17 with the second side plate 18 is also equipped with guide rail 110, and both ends of the first roller 12 are slidably connected with the guide rail 110 by the sliding block 19, so that the first roller 12 can slide in a certain direction, and the resistance during sliding is smaller, so as to reduce the output power of the first motor 13.
[0029] Further, the first side plate 17 with the second side plate 18 is also equipped with second roller 14;Wherein, the first side plate 17 and the second side plate 18 are both equipped with guide rod 11, and both ends of the second roller 14 are slidably connected with the guide rod 11, so that the second roller 14 is used to further tension the passing film material, and it can automatically move by using its own weight and the tension of the film material, so as to realize the tensioning of the film material and further reduce the power consumption of the equipment.
[0030] The existing die cutting roller needs to use the corresponding die cutting roller when cutting different styles of products, for example, when cutting the film material with a style size of 50cm long, the die cutting roller with a circumference of 50cm needs to be used, and when cutting the film material with a style size of 100cm long, the die cutting roller with a circumference of 100cm needs to be used.
[0031] The die-cutting assembly 3 comprises a frame 30, a first die-cutting roller 31 is arranged on the frame 30, and a second die-cutting roller 32 is arranged above the first die-cutting roller 31; and fixed grooves 39 are arranged on the circumferential surfaces of the first die-cutting roller 31 and the second die-cutting roller 32. Since different styles of knife blades can be replaced on the two die-cutting rollers, when the style is changed, the knife blade is only needed to be taken out from the fixed groove 39, the required knife blade is replaced, and the two ends of the replaced knife blade are fixed in the fixed groove 39, so that the die-cutting of different styles of products can be completed without replacing the die-cutting rollers. For example, when the die-cutting of a 100cm style is needed, the knife blade with a 100cm style is fixed in the fixed groove 39, so that the product with a 100cm style can be directly cut; when the die-cutting of a 50cm style is needed, the knife blade with a 50cm style is fixed in the fixed groove 39, so that the die-cutting of the film material with a 50cm style can be completed without replacing the first die-cutting roller 31 and the second die-cutting roller 32.
[0032] Specifically, when the first die-cutting roller 31 and the second die-cutting roller 32 with a circumference of 100cm are used to die-cut a 50cm film material, the second motor 112 on the feeding rack 1 stops working, so that the feeding roller 111 stops conveying the film material; when the film material stops being conveyed, the third motor 311 on the frame 30 drives the first die-cutting roller 31 to reset, that is, the 50cm long knife blade is rotated to the initial position, and then the second motor 112 and the third motor 311 are started to promote the film material to be smoothly cut. In addition, the first motor 13, the second motor 112 and the third motor 311 are preferably servo motors, and the transmission belt 15 is preferably a belt.
[0033] Further, since the fixed groove 39 is connected with the pressing strip 310, when the two ends of the knife blade are placed in the fixed groove 39, the pressing strip 310 is pressed in the fixed groove 39 to further fix the knife blade; wherein the pressing strip 310 can be fixed by a fastener such as a bolt penetrating through the pressing strip 310 and being connected with the internal thread hole on the fixed groove 39, so as to ensure that the knife blade works stably and reliably.
[0034] In order to conveniently adjust the gap between the first die-cutting roller 31 and the second die-cutting roller 32, the two ends of the second die-cutting roller 32 are connected with the frame 30 through the sliding blocks 35, and the upper end of the frame 30 is further provided with an adjusting assembly 34, and the gap between the second die-cutting roller 32 and the first die-cutting roller 31 is adjusted through the adjusting assembly 34.
[0035] Specifically, the upper end of the frame 30 is further provided with a fixed plate 33, the adjusting assembly 34 comprises a connecting seat 36 fixed on the fixed plate 33 and a top rod 37 moving in the connecting seat 36; the top rod 37 moves in the connecting seat 36, so that one end of the top rod 37 promotes the sliding block 35 to move.
[0036] In summary, the rotation of the jacking rod 37 in the connecting seat 36 can promote the movement of the second die cutting roller 32 to the first die cutting roller 31, and based on this, the gap between the two die cutting rollers can be freely and conveniently adjusted. The jacking rod 37 and the connecting seat 36 are in threaded cooperation, that is, the outer wall surface of the jacking rod 37 has external threads, and the inner wall surface of the connecting seat 36 has internal threads.
[0037] Further, since the jacking rod 37 is connected with the fixing member 38 at one end penetrating the fixing plate 33, and the jacking rod 37 is fixed on the fixing plate 33 through the fixing member 38, the jacking rod 37 after position movement is locked by the fixing member 38, so that the gap between the two die cutting rollers can be kept after adjustment. The fixing member 38 can be a nut or a clamp.
[0038] In addition, since the one end of the stacking frame 2 is also provided with a waste collecting port 20, and the waste generated by the die cutting assembly 3 is collected through the waste collecting port 20, the device can timely discharge the generated waste while producing normally. Specifically, the stacking frame 2 is also provided with a waste discharge port 21 communicating with the waste collecting port 20.
[0039] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
