[0002] The die-cutting machine safety device is a protection system designed specifically for carton die-cutting machines to reduce the risk of operators being scratched by sharp knife dies during paper material replacement. The system usually includes mechanical guardrails, photoelectric sensors and emergency stop controls. The mechanical guardrails surround the die-cutting area to prevent operators from directly contacting the blades. The photoelectric sensors can detect whether the operator's arms or other body parts enter the danger zone and automatically stop the machine when intrusion is detected. The emergency stop control allows the operator to quickly stop the machine when potential danger is discovered. These safety measures work together to greatly improve the operational safety of the die-cutting machine.

[0003] In the actual process of the existing carton die-cutting machine, since the paper material is replaced by manual intervention, and since the knife die is usually sharp, the operator is easily scratched by the knife die during the process of replacing the paper material. In view of this, we provide a safety protection device for the carton die-cutting machine. Utility Model Content

[0006] As mentioned above, a positioning plate is slidably connected to the top of the inner part of the slide rail, and the top of the outer wall of the positioning plate is slidably connected to one side of the inner part of the bottom mold. Both sides of the inner part of the bottom mold are slidably connected to pressure plates, and the center of the bottom surface of the pressure plate and the center of the top surface of the positioning plate are in contact with each other.

[0007] As mentioned above, a plurality of positioning springs are fixedly connected to the center of the bottom surface of the positioning plate, and the outer wall of the bottom end of the positioning spring is fixedly connected to the bottom end of the inner wall of the slide rail.

[0008] As mentioned above, a group of corresponding limit strips are fixedly connected on both sides of the inner wall of the slide rail, and the limit strips are located on both sides of the interior of the positioning plate. The top of the outer wall of the limit strip is connected through one side of the bottom surface of the positioning plate, and one side of the interior of the positioning plate is slidably connected to the outer wall of one side of the limit strip.

[0009] As mentioned above, the top end of the top mold is fixedly connected to a control motor, and the center of the top mold is rotatably connected to a threaded shaft, and the center of the top surface of the threaded shaft is fixedly connected to the output end of the control motor.

[0010] As mentioned above, a connecting plate is slidably connected to the inner center of the top mold, and the connecting plate is located at the center of the outer wall of the threaded shaft.

[0012] Compared with the prior art, the safety protection device for carton die-cutting machine has the following beneficial effects:

[0013] 1. When the concave printing on the surface of the bottom mold is worn, the pressing plate is pressed toward the inside of the bottom mold, and the positioning plate is pushed toward the center of the inside of the slide rail through the pressing plate, and the bottom mold is pulled out along the outer wall of the slide rail, and then another prepared bottom mold is aligned with the slide rail. The operator presses the positioning plate toward the inside of the slide rail with his fingers, and the bottom mold slides along the outer wall of the slide rail. When the bottom mold drives the pressing plate to reach the top center of the positioning plate, the positioning spring pushes the positioning plate toward the center of the inside of the bottom mold, and pushes the pressing plate toward the top of the inside of the bottom mold, so that the two sides of the outer wall of the positioning plate and the two sides of the inner wall of the bottom mold are attached to and in conflict with each other, and the bottom mold can be replaced, thereby realizing the rapid disassembly and replacement of the bottom mold through the cooperation of the positioning plate and the pressing plate.

Since the top die limits the connecting plate through the slots on both sides of the interior, the connecting plate can only slide vertically along the inner wall of the top die. When the control motor drives the threaded shaft to rotate, the threaded shaft slides the connecting plate and the cutting die toward the top of the top die through the outer wall thread, so that the cutting die can be retracted into the top of the top die. Therefore, the contraction of the cutting die is realized through the mutual cooperation of the connecting plate and the threaded shaft, and the operator is effectively protected to avoid being scratched by the cutting die when changing the paper material.

[0015] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and will be apparent to those skilled in the art based on the following examination and study, or may be taught from the practice of the present invention to some extent.

DETAILED DESCRIPTION

[0021] 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.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: a safety protection device for a carton die-cutting machine, comprising a base 1, a plurality of work frames 2 are fixedly connected at the edges of the top surface of the base 1, and the outer walls of the corresponding sides of the work frames 2 are fixedly connected with slide rails 201, the slide rails 201 are located on both sides of the top of the base 1, and the center of the top surface of the base 1 is slidably connected with a bottom mold 3 through the slide rails 201, a telescopic cylinder 301 is fixedly connected to the outer wall of the top end of the work frame 2, and a top mold 302 is fixedly connected to the outer wall of the telescopic end of the telescopic cylinder 301, the top mold 302 is located at the top center of the bottom mold 3, and the top mold 302 is slidably connected to the top center of the bottom mold 3 through the telescopic cylinder 301, a concave printing 303 is provided at the center of the top surface of the bottom mold 3, and a knife mold 304 is slidably connected to the bottom end of the top mold 302.

[0023] When the concave printing 303 on the surface of the bottom mold 3 is worn, the pressing plate 203 is pressed toward the inside of the bottom mold 3, and the positioning plate 202 is pushed toward the inner center of the slide rail 201 along the outer wall of the limit strip 205 through the pressing plate 203. At the same time, the bottom surface of the slide rail 201 is compressed by the positioning spring 204, and the bottom mold 3 is pulled out along the outer wall of the slide rail 201, and then the other prepared bottom mold 3 is aligned with the slide rail 201. The operator presses the positioning plate 202 toward the inside of the slide rail 201 with his fingers. After the positioning plate 202 is returned to the inner center of the slide rail 201, the bottom mold 3 can slide along the outer wall of the slide rail 201. When the bottom mold 3 drives the pressing plate 203 to reach the top center of the positioning plate 202, the top surface of the positioning plate 202 loses the thrust from the top of the inner wall of the bottom mold 3, and the positioning spring 204 pushes the positioning plate 202 toward the inner center of the bottom mold 3, pushing the pressing plate 203 toward the inner center of the bottom mold 3. The bottom mold 304 can be replaced by pushing the end to make the two sides of the outer wall of the positioning plate 202 and the two sides of the inner wall of the bottom mold 3 fit together and conflict with each other. When the device cooperates with the cutting die 304 and the gravure 303 to complete the paper processing, the control motor 305 is driven. Since the top mold 302 limits the connecting plate 307 through the grooves on both sides of the interior, the connecting plate 307 can only slide vertically along the inner wall of the top mold 302. When the control motor 305 drives the threaded shaft 306 to rotate, the threaded shaft 306 slides the connecting plate 307 and the cutting die 304 toward the top of the top mold 302 through the outer wall thread, so that the cutting die 304 can be retracted into the top of the top mold 302. Thereby, the contraction of the cutting die 304 is realized through the mutual cooperation of the connecting plate 307 and the threaded shaft 306, and the operator is effectively protected to avoid being scratched by the cutting die 304 when replacing the paper.

[0024] like Figure 1-3 As shown, a positioning plate 202 is slidably connected to the top of the inner top of the slide rail 201, and the top of the outer wall of the positioning plate 202 is slidably connected to one side of the inner part of the bottom mold 3, and pressure plates 203 are slidably connected to both sides of the inner part of the bottom mold 3, and the center of the bottom surface of the pressure plate 203 and the center of the top surface of the positioning plate 202 are in contact with and in conflict with each other, and a plurality of positioning springs 204 are fixedly connected to the center of the bottom surface of the positioning plate 202 at the same time, and the outer wall of the bottom end of the positioning spring 204 is fixedly connected to the bottom end of the inner wall of the slide rail 201, and a group of corresponding limit strips 205 are fixedly connected to both sides of the inner wall of the slide rail 201 at the same time, and the limit strips 205 are located on both sides of the inner part of the positioning plate 202, the top of the outer wall of the limit strip 205 is connected through one side of the bottom surface of the positioning plate 202, and one side of the inner part of the positioning plate 202 is slidably connected to the outer wall of one side of the limit strip 205.

[0025] When the concave printing 303 on the surface of the bottom mold 3 is worn, the pressing plate 203 is pressed toward the inside of the bottom mold 3, and the positioning plate 202 is pushed toward the inner center of the slide rail 201 along the outer wall of the limit strip 205 through the pressing plate 203. At the same time, the bottom surface of the slide rail 201 compresses the positioning spring 204, and then the bottom mold 3 is pulled out along the outer wall of the slide rail 201. Then, another prepared bottom mold 3 is aligned with the slide rail 201. The operator presses the positioning plate 202 toward the inside of the slide rail 201 with his fingers. After the positioning plate 202 is returned to the inner center of the slide rail 201, the bottom mold 3 can be moved along the outer wall of the slide rail 201. The outer wall of the slide rail 201 slides, and when the bottom mold 3 drives the pressure plate 203 to reach the top center of the positioning plate 202, since the top surface of the positioning plate 202 loses the thrust from the top of the inner wall of the bottom mold 3, the positioning spring 204 pushes the positioning plate 202 toward the inner center of the bottom mold 3, and pushes the pressure plate 203 toward the top of the bottom mold 3, so that the two sides of the outer wall of the positioning plate 202 and the two sides of the inner wall of the bottom mold 3 are in contact with each other, and the bottom mold 3 can be replaced, so that the positioning plate 202 and the pressure plate 203 cooperate with each other to achieve rapid disassembly and replacement of the bottom mold 3.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a control motor 305 is fixedly connected to the top of the top mold 302, and a threaded shaft 306 is rotatably connected to the center of the top mold 302. The center of the top surface of the threaded shaft 306 is fixedly connected to the output end of the control motor 305. A connecting plate 307 is slidably connected to the center of the top mold 302, and the connecting plate 307 is located at the center of the outer wall of the threaded shaft 306. Both ends of the outer wall of the connecting plate 307 pass through both sides of the inner wall of the top mold 302 and are fixedly connected to the top of the inner wall of the cutting mold 304. The cutting mold 304 is slidably connected to the bottom end of the top mold 302 through the connecting plate 307 and the threaded shaft 306.

[0027] When the device completes paper processing through the cooperation of the cutting die 304 and the gravure 303, the control motor 305 is driven. Since the top mold 302 limits the connecting plate 307 through the slots on both sides of the interior, the connecting plate 307 can only slide vertically along the inner wall of the top mold 302. After the control motor 305 drives the threaded shaft 306 to rotate, the threaded shaft 306 slides the connecting plate 307 and the cutting die 304 toward the top of the top mold 302 through the outer wall thread, so that the cutting die 304 can be retracted into the top of the top mold 302. Therefore, the contraction of the cutting die 304 is achieved through the cooperation of the connecting plate 307 and the threaded shaft 306, and the operator is effectively protected from being scratched by the cutting die 304 when replacing the paper.

[0028] Working principle: When the concave printing 303 on the surface of the bottom mold 3 is worn, the pressing plate 203 is pressed toward the inside of the bottom mold 3, and the positioning plate 202 is pushed toward the inner center of the slide rail 201 along the outer wall of the limit strip 205 through the pressing plate 203. At the same time, after the bottom surface of the slide rail 201 compresses the positioning spring 204, the bottom mold 3 is pulled out along the outer wall of the slide rail 201, and then another prepared bottom mold 3 is aligned with the slide rail 201. The operator presses the positioning plate 202 toward the inside of the slide rail 201 with his fingers, and after the positioning plate 202 is returned to the inner center of the slide rail 201, the bottom mold 3 can slide along the outer wall of the slide rail 201. When the bottom mold 3 drives the pressing plate 203 to the top center of the positioning plate 202, the positioning spring 204 pushes the positioning plate 202 toward the bottom mold 3 after the top surface of the positioning plate 202 loses the thrust from the top of the inner wall of the bottom mold 3. The inner center pushes and pushes the pressing plate 203 toward the inner top of the bottom mold 3, so that the two sides of the outer wall of the positioning plate 202 and the two sides of the inner wall of the bottom mold 3 are attached to and in conflict with each other, and the bottom mold 3 can be replaced. When the device cooperates with the cutting die 304 and the gravure 303 to complete the paper processing, the control motor 305 is driven. Since the top mold 302 limits the connecting plate 307 through the grooves on both sides of the interior, the connecting plate 307 can only slide vertically along the inner wall of the top mold 302. After the control motor 305 drives the threaded shaft 306 to rotate, the threaded shaft 306 slides the connecting plate 307 and the cutting die 304 toward the inner top of the top mold 302 through the outer wall thread, the cutting die 304 can be retracted into the inner top of the top mold 302, thereby realizing the contraction of the cutting die 304 through the mutual cooperation of the connecting plate 307 and the threaded shaft 306.
