Description

Technical Field

[0001] The present application relates to the technical field of circular knife machines, and more specifically, to a circular knife machine for preventing material deviation during die cutting. Background Art

[0002] Circular knife machine, a type of die-cutting machine, is also called rotary machine, rotary die-cutting machine, rolling cutter machine, etc. It is named circular knife machine because the die used is made of solid metal cylinder, which is different from flat knife die. It is a common name in the die-cutting industry. It uses a circular knife to continuously rotate and die-cut.

[0003] In actual use, in order to ensure that the coil can have better tension, the existing circular knife machine generally adopts a unique design, that is, multiple sets of transmission rollers are carefully arranged in a staggered manner. This layout cleverly guides the direction of the coil, making it present an S-shaped curved distribution shape. Through this complex but effective method, the tension on the coil is greatly increased, so that the coil is tightly stretched and straightened, creating extremely favorable conditions for subsequent die-cutting processing. However, when the coil is fed in the die-cutting process, a significant problem is exposed. Since the coil cannot obtain an effective limiting effect during the feeding process, its stability during the transmission process is poor, which easily causes the coil to tilt, which will directly interfere with the accuracy of die-cutting and ultimately have an adverse effect on the quality of the finished product.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] Reference Figure 1-Figure 5 , a circular knife machine for preventing material deviation during die cutting, comprising a workbench 1, two fixed plates 2 are arranged above the workbench 1, and an anti-deflection component is arranged between the two fixed plates 2;

[0030] The anti-deflection component includes a connecting rod 10, and the number of the connecting rods 10 is set to two. The two connecting rods 10 are respectively fixedly connected to the corresponding fixed plates 2. The facing ends of the two connecting rods 10 are fixedly connected to a limit box 11. The inner sides of the two limit boxes 11 are provided with limit grooves. The insides of the two limit grooves are fixedly connected with two arc blocks 14. An auxiliary component is provided between the two fixed plates 2.

[0031] During the die-cutting process, because the limit box 11 itself is fixed on the connecting rod 10, it provides a clear boundary for both sides of the material. When the material is in the process of transmission and die-cutting, its two sides are blocked and restricted by the limit box 11 and the arc block 14 and cannot exceed the limited range, thereby playing a limiting role in the horizontal direction, preventing the material from shifting during the processing, improving the precision and accuracy of die-cutting, and reducing the problems of dimensional deviation and irregular shape caused by offset, thereby improving the quality and consistency of the product.

[0032] Reference Figure 3-Figure 5 There are two groups of auxiliary components, each group of auxiliary components includes a telescopic rod 12, the number of telescopic rods 12 is set to two, the outer walls of the two telescopic rods 12 are sleeved with springs 13, the facing ends of the two telescopic rods 12 are fixedly connected with a placement frame 15, the interior of the two placement frames 15 are provided with a clamping wheel 17, both ends of each group of placement frames 15 are fixedly connected with a magnetic block 16, every two upper and lower corresponding magnetic blocks 16 are magnetically connected, the two limit boxes 11 are located on one side of the corresponding clamping wheel 17, the inner side of the fixed plate 2 is fixedly connected with two connecting plates 9, the two connecting plates 9 are respectively fixedly connected to the corresponding telescopic rods 12, and each spring 13 is respectively fixedly connected to the corresponding connecting plate 9 and the placement frame 15.

[0033] When the material is conveyed, downward pressure can be applied to the pressure wheel 17 through the setting of the telescopic rod 12 and the spring 13, so that the pressure wheel 17 can be pressed on the cloth. Because the upper and lower corresponding magnetic suction blocks 16 are magnetically connected, the pressure wheel 17 can better ensure full contact with the surface of the material without leaving any gaps, thereby improving the effectiveness of the clamping, effectively preventing the material from loosening and deflecting during the die-cutting process, improving the stability of the clamping, and ensuring the accuracy of the die-cutting.

[0034] Reference Figure 1-Figure 2 A motor 3 is provided on the top of the workbench 1, and the output end of the motor 3 is connected to a transmission gear 4 through a rotating shaft. A circular knife 6 and an auxiliary roller 7 are rotatably connected to the inner sides of the two fixed plates 2. One end of the rotating shaft inside the circular knife 6 and the auxiliary roller 7 is fixedly connected to a driving gear 5. The two driving gears 5 are meshed with each other, and one of the driving gears 5 is meshed with the transmission gear 4. A blanking plate 8 is fixedly connected to one end of the two fixed plates 2 away from the connecting plate 9.

[0035] When die-cutting the material, the motor 3 is started first, and its output end drives the transmission gear 4 to rotate through the rotating shaft. The transmission gear 4 is engaged with one of the driving gears 5, thereby driving the driving gear 5 to rotate. Since the two driving gears 5 are engaged, the circular knife 6 and the auxiliary roller 7 can rotate synchronously in opposite directions to achieve the die-cutting process of the material.

[0036] Working principle: When die-cutting the material, first start the motor 3. The output end of the motor 3 drives the transmission gear 4 to rotate through the rotating shaft. The transmission gear 4 meshes with one of the driving gears 5, so that the circular knife 6 and the auxiliary roller 7 can rotate synchronously in opposite directions to die-cut the material. During the material conveying process, the anti-deviation component plays a role. The limit box 11 fixedly connected on the two connecting rods 10 and the internal arc block 14 provide clear boundaries for both sides of the material. During the transmission and die-cutting process, the material is blocked and restricted by the limit box 11 and the arc block 14 on both sides and cannot exceed the limited range, thereby playing a limiting role in the horizontal direction, preventing the material from shifting during the processing process, and ensuring the precision and accuracy of the die-cutting.

[0037] At the same time, the auxiliary components also work together. The telescopic rod 12 and the sleeved spring 13 in each group of auxiliary components provide downward pressure for the clamping wheel 17, so that the clamping wheel 17 can be pressed on materials such as cloth. The magnetic blocks 16 at both ends of the placement frame 15 are magnetically connected, which enables the clamping wheel 17 to ensure full contact with the surface of the material without leaving any gaps, thereby improving the effectiveness of the clamping, effectively preventing the material from loosening and deviating during the die-cutting process, improving the stability of the clamping, and ensuring the accuracy of the die-cutting.

[0038] Finally, the precise die-cutting of the material is achieved through the coordinated rotation of the circular knife 6 and the auxiliary roller 7. The die-cut material falls onto the blanking plate 8 and is then collected by the staff.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
