DETAILED DESCRIPTION

[0027] The embodiment of the present invention provides a positioning die-cutting device and a method of using the same, which are used to solve the technical problems in the prior art that the utilization rate of materials and machines of circular knife die-cutting machines is low, and because the die-cutting area cannot be accurately positioned, the material after one die-cutting is wasted as waste and cannot be reused.

[0028] The overall idea of ​​the technical solution provided by the present invention is as follows:

[0029] The positioning die-cutting device includes: a first connecting rod 100 and a second connecting rod 200, wherein the first ends of the first connecting rod 100 and the second connecting rod 200 are connected by a first fixing member 300; the second ends of the first connecting rod 100 and the second connecting rod 200 are connected by a first gear member 400, and there is a certain distance between the first connecting rod 100 and the second connecting rod 200; a first fixing bracket 500, which is rotatably connected to the first fixing member 300; a second fixing bracket 600, which is rotatably connected to the first gear member 400; wherein a gear adjustment member 700 is provided on the second fixing bracket 600, and the gear adjustment member 700 is meshed and connected with the first gear member 400. According to the curve principle, the greater the fluctuation, the longer the curve length, and vice versa, the smoother the fluctuation, the shorter the curve length. By adjusting the gear adjustment member 700, the gear adjustment member 700 drives the first gear member 400 to rotate, thereby adjusting the angle of the first connecting rod 100 and the second connecting rod 200. In actual use, the material strip passes through the first connecting rod 10 0 and the second connecting rod 200, and adjusting the angles of the first connecting rod 100 and the second connecting rod 200 to achieve fluctuation control of the material strip. Because the material is generally set on the material strip, the first connecting rod 100 and the second connecting rod 200 control the different distances of the material from the die-cutting area when they are at different angles. It is necessary to adjust the angles of the first connecting rod 100 and the second connecting rod 200 so that the material is positioned just below the die-cutting area to achieve the purpose of positioning. Generally, the material after the first die-cutting enters the second material strip, and the second material strip is re-fed for the second die-cutting after passing through between the first connecting rod 100 and the second connecting rod 200, wherein the second material strip is positioned between the first connecting rod 100 and the second connecting rod 200, so that the material is just positioned in the die-cutting area after re-feeding for the second die-cutting, thereby realizing accurate positioning of the die-cutting area and performing the second die-cutting, thereby solving the technical problem that the circular knife die-cutting machine in the prior art generally has low material and machine utilization rate, and the material after one die-cutting is wasted as waste and cannot be reused because the die-cutting area cannot be accurately positioned.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 3A positioning die-cutting device provided in an embodiment of the present invention includes: a first connecting rod 100, a second connecting rod 200, a first fixing member 300, a first gear member 400, a first fixing bracket 500, a second fixing bracket 600 and a gear adjusting member 700.

[0033] The first ends of the first connecting rod 100 and the second connecting rod 200 are connected by a first fixing member 300, and the second ends of the first connecting rod 100 and the second connecting rod 200 are connected by a first gear member 400. There is a certain distance between the first connecting rod 100 and the second connecting rod 200, so that the material belt can pass through between the first connecting rod 100 and the second connecting rod 200. More preferably, the first ends of the first connecting rod 100 and the second connecting rod 200 are both rotatably connected to the first fixing member 300, and the second ends of the first connecting rod 100 and the second connecting rod 200 are both rotatably connected to the first gear member 400. The first connecting rod 100 and the second connecting rod 200 are arranged in parallel, so that the material belt can be completely attached to the first connecting rod 100 and the second connecting rod 200. When the material belt slides on the first connecting rod 100 and the second connecting rod 200, the rotation of the first connecting rod 100 and the second connecting rod 200 makes the sliding assistance of the material belt smaller and the production efficiency higher.

[0034] Among them, the first fixed bracket 500 is rotatably connected to the first fixed member 300, the second fixed bracket 600 is rotatably connected to the first gear member 400, the first fixed bracket 500 and the second fixed bracket 600 are fixedly arranged at designated positions, the first fixed member 300 rotates on the first fixed bracket 500, and the first gear member 400 rotates on the second fixed bracket 600, so that the first fixed member 300 and the first gear member 400 drive the first connecting rod 100 and the second connecting rod 200 to rotate between the first fixed bracket 500 and the second fixed bracket 600.

[0035] Among them, a gear adjustment member 700 is provided on the second fixed bracket 600, and the gear adjustment member 700 is meshed and connected with the first gear member 400. The gear adjustment member 700 makes the first gear member 400 rotate, and the first gear member 400 drives the positions of the first connecting rod 100 and the second connecting rod 200 to change. Generally, the material belt is divided into three sections when passing through the first connecting rod 100 and the second connecting rod 200. The first section refers to the material belt before entering the first connecting rod 100, and the second section refers to the material belt between entering the first connecting rod 100 and the second connecting rod 200. The third section is when the material strip comes out from the second connecting rod 200, wherein the positions of the first connecting rod 100 and the second connecting rod 200 change, so that the angle between the first section and the second section changes, and the angle between the third section and the second section also changes. Similar to the curve principle, the first connecting rod 100 and the second connecting rod 200 change the fluctuation of the material strip. The greater the fluctuation, the longer the curve length. Conversely, the smoother the fluctuation, the shorter the curve length. By utilizing this characteristic, the material on the material strip can be positioned just below the die-cutting area, thereby realizing the positioning of the material on the material strip.

[0036] In one embodiment, see Figure 1 and Figure 2 The gear adjustment member includes: an adjusting slide rod 710; a second gear member 720, which is fixedly arranged on the adjusting slide rod 710, and the second gear member 720 is meshed and connected with the first gear member 400; wherein the adjusting slide rod 710 is rotatably connected with the second fixed bracket 600, and by rotating the adjusting slide rod 710, the adjusting slide rod 710 drives the second gear member 720 to rotate. Since the second gear member 710 is meshed and connected with the first gear member 400, the rotation of the second gear member 720 will drive the first gear member 400 to rotate, that is, the first gear 400 rotates relative to the second fixed bracket 600, and the first gear member 400 drives the first connecting rod 100 and the second connecting rod 200 to rotate between the first fixed bracket 500 and the second fixed bracket 600. The user can adjust the positions of the first connecting rod 100 and the second connecting rod 200 by rotating the adjusting slide rod 710, which is convenient to use.

[0037] Furthermore, the second fixing bracket 600 has a channel in it, the adjusting slide rod 710 is arranged in the channel, and the adjusting slide rod 710 rotates in the channel; the second fixing bracket 600 is provided with a locking knob 610, the locking knob 610 is threadedly connected to the second fixing bracket 600, one end of the locking knob 610 is connected to the channel, and the locking knob 610 fixes the adjusting slide rod 710 by mechanical spinning. Since the locking knob 610 is threadedly connected to the second fixing bracket 600 and one end of the locking knob 610 is connected to the channel, the locking knob 610 is rotated to fix the adjusting slide rod 710. When the locking knob 610 is close to or away from the channel, the adjusting slide rod 710 is arranged in the channel, and one end of the locking knob 610 is close to or away from the adjusting slide rod 710. When the locking knob 610 is close to the adjusting slide rod 710, the locking knob 610 will press the adjusting slide rod 710 tightly to fix the adjusting slide rod 710. When the locking knob 610 is away from the adjusting slide rod 710, the adjusting slide rod 710 can rotate. Preferably, the adjusting slide rod 710 is also provided with anti-slip patterns, which can be a plurality of grooves or protrusions, so that the friction between one end of the locking knob 610 and the adjusting slide rod 710 is increased, and the fixing effect is better.

[0038] In one embodiment, a second fixing member 410 is fixedly provided in the middle of the first gear member 400, and the first connecting rod 100 and the second connecting rod 200 are connected to the second fixing member 410, wherein the second fixing member 410 serves to fix the positions of the first connecting rod 100 and the second connecting rod 200. More preferably, the first ends of the first connecting rod 100 and the second connecting rod 200 are both rotatably connected to the first fixing member 410, so that when the material belt slides on the first connecting rod 100 and the second connecting rod 200, the rotation of the first connecting rod 100 and the second connecting rod 200 makes the sliding assistance of the material belt smaller.

[0039] In one embodiment, see Figure 3 A positioning die-cutting device also includes a circular knife die-cutting device 800, which includes a first bottom roller 810 and a second bottom roller 820, and a knife die 830 is arranged between the first bottom roller 810 and the second bottom roller 820, wherein the first die-cutting is realized between the first bottom roller 810 and the knife die 830, and the second die-cutting is realized between the second bottom roller 820 and the knife die 830. It can be understood that the first bottom roller 810 is rotated under the action of the first power bottom roller 850 and the first power source 840, thereby driving the first material strip 10 to enter between the first bottom roller 810 and the knife die 830 for die-cutting. Specifically, the first power source 840 drives the first power bottom roller 850 to rotate, and the first power bottom roller 850 drives the first bottom roller 810 to rotate, thereby enabling the first bottom roller 810 to rotate.

[0040] Furthermore, a positioning die-cutting device also includes a conveying device 900, the conveying device 900 includes a third bottom roller 910, a fourth bottom roller 920 and a rubber roller 930, the third bottom roller 910 is arranged between the rubber roller 930 and the fourth bottom roller 920, wherein after the first material strip 10 is first die-cut between the first bottom roller 810 and the knife die 830, the cut material follows the first material strip 10 into between the third bottom roller 910 and the fourth bottom roller 920, the fourth bottom roller 920 rotates and drives the first material strip 10 to enter the next process, and at the same time the rubber roller 930 and the third bottom roller 910 drive the second material strip 20 to enter, and the second material strip 20 passes between the first connecting rod 100 and the second connecting rod 200 and then enters between the second bottom roller 820 and the knife die 830, as shown in FIG. Figure 3 As shown in A in the middle, the material after the first die-cutting goes up and adheres to the second material belt 20 and moves with the second material belt 20, that is, the material after the first die-cutting is driven by the second material belt 20 to enter between the second bottom roller 820 and the knife die 830 for the second die-cutting. It can be understood that the fourth bottom roller 920 is rotated under the action of the second power bottom roller 940 and the second power source 950, thereby driving the second material belt 20 to enter between the fourth bottom roller 920 and the third bottom roller 910. Specifically, the second power source 950 drives the second power bottom roller 940 to rotate, and the second power bottom roller 940 drives the fourth bottom roller 920 to rotate. The fourth bottom roller 920 is moved, thereby rotating. Through the cooperation of the circular knife die-cutting device 800 and the conveying device 900, die-cutting can be carried out on the machine while recycling. At the same time, since the material after the first die-cutting is attached to the second material belt 20 and moves driven by the second material belt 20, deformation and wrinkles of the material during the bonding process are avoided. A knife die 830 is used for circular circulation operation. After the material after the first die-cutting is accurately positioned to the die-cutting area by the first connecting rod 100 and the second connecting rod 200, the second die-cutting is carried out, thereby doubling the material utilization rate, saving labor and improving the machine utilization rate.

[0041] Embodiment 2

[0042] Figure 4 A method for using a positioning die-cutting device according to an embodiment of the present invention comprises:

[0043] S100, placing the material on a first material strip, and the first material strip is subjected to a first die-cutting by a circular die-cutting device;

[0044] S200, the material after the first die-cutting is discharged from the knife and is bonded to the second material belt by the power of the equipment;

[0045] S300, the second material strip with the material enters between the first connecting rod and the second connecting rod, and then enters the circular knife die-cutting device for the second die-cutting. By adjusting the gear adjustment part, the first gear part is driven to rotate, thereby adjusting the angle of the first connecting rod and the second connecting rod, so that the relative position of the second material strip and the blade of the circular knife die-cutting device changes.

[0046] Specifically, in actual use, the material to be die-cut is placed on the first material belt, and the first material belt carries the material into the circular knife die-cutting device for the first die-cutting. After the first die-cutting, the material is directly bonded to the second material belt by the power of the equipment after exiting the knife, so that the material after the first die-cutting moves under the drive of the second material belt 20, thereby avoiding the deformation and wrinkling of the material during the bonding process; the second material belt carries the material into between the first connecting rod and the second connecting rod, and then enters the circular knife die-cutting device for the second time for die-cutting, and the first gear part is driven to rotate by adjusting the gear adjustment part, thereby adjusting the angle of the first connecting rod and the second connecting rod, so that the relative position of the second material belt and the blade of the circular knife die-cutting device changes, and the material on the second material belt is just located in the die-cutting area of ​​the circular knife die-cutting device, thereby realizing the positioning of the material on the second material belt, so that the material die-cut out of the first time can be directly die-cut for the second time, thereby improving material utilization and production efficiency.

[0047] Furthermore, the circular knife die-cutting device includes a first bottom roller and a second bottom roller, and a knife die is arranged between the first bottom roller and the second bottom roller; the first material strip enters between the knife die and the first bottom roller for the first die-cutting; the second material strip enters between the knife die and the second bottom roller for the second die-cutting. Since the first die-cutting and the second die-cutting are both cut by the same knife die, the labor cost and production cost are effectively saved, and the machine utilization rate is improved.

[0048] In summary, the above one or more technical solutions in the embodiments of the present application have at least one or more of the following technical effects:

[0049] A positioning die-cutting device and a method of using the same provided in an embodiment of the present invention include: a first connecting rod 100, a second connecting rod 200, a first fixing member 300, a first gear member 400, a first fixing bracket 500, a second fixing bracket 600 and a gear adjusting member 700. The curve principle is used. The greater the fluctuation, the longer the curve length. On the contrary, the smoother the fluctuation, the shorter the curve length. By adjusting the gear adjusting member 700, the gear adjusting member 700 drives the first gear member 400 to rotate, thereby adjusting the angle of the first connecting rod 100 and the second connecting rod 200. In actual use, the material strip passes between the first connecting rod 100 and the second connecting rod 200. The angle of the first connecting rod 100 and the second connecting rod 200 is adjusted to achieve the fluctuation control of the material strip. Because the material is generally set on the material strip, the first connecting rod 100 and the second connecting rod 200 are adjusted. When 200 is at different angles, it controls the different distances of the material from the die-cutting area. It is necessary to adjust the angles of the first connecting rod 100 and the second connecting rod 200 so that the material is positioned just below the die-cutting area to achieve the purpose of positioning. Generally, the material after the first die-cutting enters the second material strip. After the second material strip passes through between the first connecting rod 100 and the second connecting rod 200, it is re-entered for a second die-cutting, wherein the second material strip is positioned between the first connecting rod 100 and the second connecting rod 200, so that the material is just positioned in the die-cutting area after re-entering for a second die-cutting, thereby achieving accurate positioning of the die-cutting area and performing a second die-cutting, thereby solving the technical problem that the circular knife die-cutting machine in the prior art generally has a low material and machine utilization rate, and the material after one die-cutting is wasted as waste and cannot be reused because the die-cutting area cannot be accurately positioned.
