Description

Technical Field

[0001] The utility model belongs to the technical field of processing, and in particular relates to a novel rapid cutting device. Background Art

[0002] During the processing of the film covering equipment, it is often necessary to cut the film covering material. For example, in the film covering of the tail flowers of chopsticks, the tail flower material needs to be first transported to the cutting device by the conveying device, and then cut to the corresponding length by the cutting device. Finally, the cut tail flower material is transported to the assembly area for combination with chopsticks.

[0003] However, the existing cutting device has high manufacturing cost and complex structure. For example, the Chinese invention patent with patent number CN201610069510.3 and the name of sleeve labeling machine discloses a sleeve labeling machine, which at least includes: a central column, a first column and a second column, wherein the first column and the second column are suspended and separated from each other, the purpose is to remove the connection between the first column and the second column, so that the diameter range of the bottle or can that the sleeve labeling machine is intended to package can be expanded to the minimum diameter, thereby increasing the applicable range; when the first column of the central column stretches the shrink film, the shrink film can be further conveyed downward by the label conveying wheel of the shrink film synchronous transmission device, and gradually sleeved into the second column of the central column, and then cut by the cutting device, and then the individual shrink film is further pulled downward by the label pulling wheel to be sleeved on the outer surface of the bottle or can, and then the bottle or can is conveyed and moved forward by the conveying device to enter the next device, and the shrink film is completely combined with the shrink packaging of the bottle or can, so that the sleeve labeling action of the bottle or can is completed. The cutting device used is equipped with multiple sets of cutters, and the end of each cutter is located in the cutting groove at a distance close to zero, so that each cutter can cut to the center point of the shrink film. Obviously, this method uses multiple sets of cutters, which is more expensive and the structure used is more complicated. Utility Model Content

[0009] Furthermore, the limit block is provided with a fixing groove for the movement of the knife handle.

[0010] Furthermore, when the pushing electromagnet is not energized, the cutter head is opened relative to the film feeding center rod, and when energized, the blade of the cutter head is engaged with the film feeding center rod.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0026] The first embodiment of the utility model is as follows Figure 1-4 As shown: a novel fast cutting device, including a machine base 1 and a film feeding center rod 7, one end of the machine base 1 is provided with a feeding channel for placing the film feeding center rod 7, an electric slip ring 20 is provided in the feeding channel, the fixed end of the electric slip ring 20 is arranged on the machine base 1, and a rotating transmission mechanism is provided on the movable end of the electric slip ring 20, and a cutting assembly is provided on the rotating transmission mechanism, one end of the film feeding center rod 7 passes through the electric slip ring 20 and the rotating transmission mechanism, and the cutting part of the cutting assembly surrounds the film feeding center rod, the electric slip ring 20 and the cutting transmission disk 31 are provided with openings for placing the film feeding center rod 7, and a bearing is provided in the opening of the cutting transmission disk 31, so that the film material on the film feeding center rod 7 can be easily transported to the cutting assembly through the opening and the bearing.

[0027] By providing an electric slip ring 20 in the feeding channel, and arranging a cutting transmission disk 31 on the movable end of the electric slip ring 20, a cutting assembly is provided on the cutting transmission disk 31, and the cutting assembly can rotate accordingly with the rotation of the cutting transmission disk 31. When in use, the film material is conveyed out from the opening in the middle of the cutting transmission disk 31 through the film conveying center rod 7 via the electric slip ring 20 in the feeding channel. Since the cutting assembly is arranged around the film conveying center rod 7, the conveyed film material is located below the cutter head 222 of the cutting assembly. When the cutting transmission disk 31 is driven to rotate by the cutting motor 30, the electric slip ring fixed to the cutting motor 30 is simultaneously driven. The ring 20 rotates, thereby triggering the pushing electromagnet 21 electrically connected to the electric slip ring 20. The pushing electromagnet 21 pushes the cutter head 222 thereon downward to make the cutter head 222 fully contact with the film material. At the same time, since the cutting component is in a high-speed rotating state, the film will pause when it reaches the color mark position on the film feeding center rod. Then the electromagnet receives the command and attracts the high-speed rotating cutter head 222 to complete 360° all-round cutting around the film material on the film feeding center rod 7. Through the above structure, only one cutter head is needed to complete the all-round cutting of the film material, and the structure is simpler, so as to solve the technical problems of high cost and complex structure of the existing cutting device.

[0029] The cutting motor 30 is arranged on the inner side of the machine base 1, and its output end extends out of the machine base 1 through an opening on the machine base 1. A pulley is provided on it, and the pulley and the cutting transmission disk 31 are connected through a belt drive. The cutting motor can drive the cutting transmission disk 31 to rotate.

[0030] like Figure 4 As shown: the cutting assembly includes a pushing electromagnet 21, a knife assembly 22 and a limit block 23. The pushing electromagnet 21 and the limit block 23 are fixed on the cutting transmission disk 31. The knife assembly 22 is arranged between the pushing electromagnet 21 and the limit block 23. The pushing electromagnet 21 and the electric slip ring 20 are electrically connected to trigger the up and down movement of the pushing end of the pushing electromagnet 21. The end of the knife assembly 22 is located in the limit block 23, and the middle part thereof is connected to the pushing end of the pushing electromagnet 21 to ensure that the knife assembly 22 can be firmly fixed on the pushing electromagnet 21.

An infrared sensing device is arranged above the chopstick conveying mechanism, and when it senses the chopsticks, it will transmit them to the control terminal. After receiving the information from the infrared sensing device, the control terminal will start the electric slip ring 20, so that the electric slip ring 20 triggers the pushing electromagnet 21, presses down the cutter head on the pushing end of the pushing electromagnet 21 and rotates at high speed around the film feeding center rod 7 to cut the film material, and the cut film material will be assembled with the chopsticks by the feeding mechanism to complete the whole process.
