Description

Technical Field

[0001] The utility model relates to the field of die-cutting mechanisms, in particular to a positioning device for die-cutting. Background Art

[0002] The die-cutting process can make printed materials or other paper products into die-cutting knife plates according to pre-designed patterns for cutting, so that the shape of the printed materials is no longer limited to straight edges and right angles. Traditional die-cutting production uses die-cutting knives to combine into die-cutting plates according to the patterns required by product design. Under the action of pressure, printed materials or other plate-like blanks are rolled into the required shape or cutting marks. The forming process uses pressure to press out line marks on the sheet material, or uses a rolling wheel to roll out line marks on the sheet material, so that the sheet material can be bent and formed according to the predetermined position.

[0003] However, since the display screen guide film has a certain hardness, the conventional die-cutting mechanism uses a conveyor belt in combination with a die-cutting process, which is not convenient for positioning the film body. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a positioning device for die cutting, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a positioning device for die-cutting, comprising a slitting machine, a cutting mechanism is arranged above the slitting machine, a positioning mechanism is arranged directly below the cutting mechanism, the positioning mechanism comprises: a die-cutting pad, a positioning roller, and a limiting support frame, both side ends of the die-cutting pad are equipped with inclined guide slopes, one end of the positioning roller passes through the limiting support frame through a rotating shaft and a feeding motor is installed inside, a friction washer is sleeved on the outer side of the positioning roller, a limiting groove is provided on the upper surface of the inclined guide slope below the limiting support frame, and a reciprocating screw rod is installed inside the limiting groove that passes through the inside of the limiting support frame.

[0006] As a further solution of the utility model: the cutting mechanism includes: a cutting frame, a die-cutting tool, and a positioning slide rod. The end of the positioning slide rod is located on the inner side of the cutting frame and is provided with a height adjustment groove. The upper surface of the cutting frame is installed with a lifting motor.

[0007] As a further solution of the utility model: a conveyor belt is arranged inside the slitting machine below the positioning mechanism, a transmission motor is installed on one side end of the conveyor belt, and a storage bin is arranged on one side end of the slitting machine.

[0008] As a further solution of the utility model: the end of the reciprocating screw is located inside the die-cutting pad and is equipped with a rolling bearing, and the limiting support frame is engaged and movable with the reciprocating screw.

[0009] As a further solution of the utility model: the limit support frame is slidably connected to the limit groove, and the die-cutting pad is movably installed above the slitting machine.

[0010] As a further solution of the utility model: the die-cutting tool is slidably connected to the height adjustment groove through the adjustment slide rod.

[0011] As a further solution of the utility model: the inclined guide slope is fixedly connected to the die-cutting pad.

[0012] As a further solution of the utility model: the die-cutting tool is movably connected to the positioning slide rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The friction washer as a whole increases the friction force with the membrane body, which facilitates feeding, and at the same time applies a certain pressure positioning on the top of the membrane body. At the same time, the limit support frame as a whole is engaged on the outside of the reciprocating screw to synchronously control the distance between the two limit support frames, so that the end of the membrane body is limited by the limit support frame to prevent the membrane body from shifting during feeding.

[0015] During die-cutting, the pressure applied by the die-cutting tool will be transmitted to the top of the die-cutting pad, which can prevent the conveyor belt from being compressed and deformed, causing the film position to shift. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the present embodiment provides a positioning device for die cutting, including a slitting machine 1, a cutting mechanism 2 is arranged above the slitting machine 1, and a positioning mechanism 3 is arranged directly below the cutting mechanism 2. The positioning mechanism 3 includes: a die cutting pad 301, a positioning roller 304, and a limit support frame 307. The die cutting pad 301 is movably installed above the slitting machine 1, and both side ends of the die cutting pad 301 are installed with inclined guide slopes 302, which are fixedly connected to the die cutting pad 301. One end of the positioning roller 304 passes through the limit support frame 307 through a rotating shaft. A feeding motor 306 is installed inside 07, and a friction washer 305 is sleeved on the outer side of the positioning roller 304. A limiting groove 303 is provided on the upper surface of the inclined guide slope 302 below the limiting support frame 307. The limiting support frame 307 is slidably connected with the limiting groove 303. The inside of the limiting groove 303 passes through the limiting support frame 307, and a reciprocating screw rod 308 is installed inside. The limiting support frame 307 is meshed with the reciprocating screw rod 308, and the end of the reciprocating screw rod 308 is located inside the die-cutting pad 301 and is installed with a rolling bearing 309.

[0024] like Figure 2-5 As shown, in this embodiment, the cutting mechanism 2 includes: a cutting frame 201, a die-cutting tool 204, and a positioning slide 205. The die-cutting tool 204 is movably connected to the positioning slide 205. The end of the positioning slide 205 is located on the inner side of the cutting frame 201 and is provided with a height adjustment groove 203. The die-cutting tool 204 is slidably connected to the height adjustment groove 203 through the positioning slide 205. A lifting motor 202 is installed on the upper surface of the cutting frame 201. A conveyor belt 4 is arranged inside the slitting machine 1 below the positioning mechanism 3. A transmission motor 5 is installed on one side end of the conveyor belt 4. A storage bin 6 is arranged on one side end of the slitting machine 1.

[0025] The working principle of the utility model is as follows: after controlling the entire cutting mechanism 2 to be installed above the slitting machine 1, the positioning mechanism 3 is placed correspondingly just below the cutting mechanism 2, and the film to be die-cut is placed above the conveyor belt 4 for transmission. After the end of the film body passes through the inclined guide slope 302 at one end of the positioning mechanism 3, the upper surface of the film body contacts the friction washer 305 below the positioning roller 304. When working, the feeding motor 306 drives the positioning roller 304 to rotate above the limiting support frame 307. The friction washer 305 increases the friction with the film body, which is convenient for feeding. At the same time, the film body will not be scratched. The outer side of the reciprocating screw 308 is meshed to synchronously control the distance between the two limit support frames 307, so that the end of the film body is limited by the limit support frame 307 to prevent the film body from shifting during feeding. After the film body is transported to the lower position of the cutting mechanism 2, the lifting motor 202 is used to control the adjustment slide bar 205 inside the die-cutting tool 204 to move downward as a whole inside the cutting mechanism 2 of the height adjustment groove 203. At the same time, the die-cutting tool 204 slides on the adjustment slide bar 205 as a whole to cut the film body. At the same time, the pressure applied by the die-cutting tool 204 during die-cutting will be transmitted to the top of the die-cutting pad 301, which can prevent the conveyor belt 4 from being compressed and deformed, resulting in the displacement of the film body position.
