Technical Field

[0001] The invention relates to a die-cutting machine, in particular to a die-cutting machine. Background Art

[0002] The die-cutting machine is mainly used to cut materials such as films, papers or packaging bags into required shapes. However, during cutting, the existing die-cutting machines require manual peeling of waste materials, which has low processing efficiency and low manual peeling efficiency, and can easily cause product damage and scrapping. Therefore, there are many disadvantages, so a waste removal device for the die-cutting machine is needed to solve these problems. Summary of the invention

[0003] In view of the deficiencies of the existing technology, the present invention provides a die-cutting machine.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a die-cutting machine, including a frame, the frame is provided with a feeding mechanism, the frame is also provided with a punching mechanism for punching the material delivered by the feeding mechanism into a desired shape, the end of the frame is provided with a conveying mechanism for conveying the finished material, and a waste stripping mechanism is provided between the conveying mechanism and the punching mechanism for stripping off the waste corners after the material is punched.

[0005] The waste stripping mechanism comprises an upper pressing roller and a lower pressing roller. The upper pressing roller has a protrusion on its outer surface, which is the same as the pattern punched by the punching mechanism. The lower pressing roller has a groove on its outer surface that matches the protrusion on the upper pressing roller.

[0006] The punching mechanism comprises a movable die and a static die, and the waste clearing and stripping mechanism always keeps synchronous lifting and lowering with the movable die.

One end of the swinging material receiving mechanism is rotatably assembled with the conveying mechanism, and the other end contacts with the waste stripping mechanism and always keeps swinging with the same lifting amplitude as the waste stripping mechanism.

[0009] The waste removal and stripping mechanism is fixedly connected with the movable mold through a fixed frame to achieve synchronous lifting or lowering or through a servo motor.

[0010] The conveying mechanism is raised and lowered synchronously with the waste removal and stripping mechanism through a servo motor.

[0011] The swinging material receiving mechanism includes a plurality of synchronously swinging material receiving plates, one end of which is assembled with the frame of the conveying mechanism through a rotating shaft or a bearing, and the lower pressure roller is provided with a plurality of annular embedding grooves corresponding to the material receiving plates, one end of which is placed in the embedding groove, and when the lower pressure roller moves upward, the material receiving plate is driven to swing up and down relative to the rotating shaft or the bearing.

[0012] The upper pressing roller and the lower pressing roller are driven by meshing, and the waste stripping mechanism keeps the feeding speed consistent with that of the feeding mechanism through a servo motor or a transmission belt.

[0020] like Figure 1-Figure 4As shown, a die-cutting machine includes a frame, and the frame is provided with a feeding mechanism, which is a conventional conveyor belt conveyor, and there is no excessive limitation on this. The frame is also provided with a punching mechanism 100 for punching the material fed by the feeding mechanism into a desired shape, and a conveying mechanism 200 for conveying finished materials is provided at the end of the frame, and a waste stripping mechanism 300 for stripping off the scraps after the material is punched is provided between the conveying mechanism 200 and the punching mechanism 100. The existing die-cutting machines do not have a waste stripping function during the processing. After the die-cutting machine is punched, the scraps are manually stripped from the raw materials to take out the finished products. However, the present device adds a waste stripping mechanism 300, which directly strips and removes the waste from the raw materials along the punching marks of the raw materials after the punching of the raw materials is completed, thereby improving the processing efficiency, increasing the yield, and reducing the cost of manual waste stripping.

[0021] The waste clearing and stripping mechanism 300 includes an upper pressing roller 310 and a lower pressing roller 320. The outer surface of the upper pressing roller 310 is provided with a protrusion 311, and the protrusion 311 is the same as the pattern punched by the punching mechanism 100. The outer surface of the lower pressing roller 320 is provided with a groove 321 adapted to the protrusion 311 on the outer surface of the upper pressing roller 310. The setting shape of the protrusion 311 of the upper pressing roller 310 is the same as the shape punched by the punching mechanism 100, thereby ensuring that the upper pressing roller 310 can cooperate with the lower pressing roller 320 to separate the finished product from the waste along the punching lines on the raw material, thereby achieving the purpose of waste clearing and stripping.

[0022] The punching mechanism 100 includes a movable mold 110 and a static mold 120. The waste stripping mechanism 300 always keeps synchronous lifting and lowering with the movable mold 110. Punching by means of the movable mold 110 and the static mold 120 is a relatively mature technology at present. The purpose of the waste stripping mechanism 300 always keeping synchronous lifting and lowering with the movable mold 110 is to ensure that the raw material can be smoothly fed into the waste stripping mechanism 300 after punching. In order to rationally utilize the equipment space and reduce the overall size of the equipment, the movable mold 110 is arranged at the bottom, and the cylinder or motor driving the movable mold 110 is arranged in the chassis, and the raw material is transported from the movable mold 110. Since the movable mold 110 always keeps lifting and lowering motion during the working process, the waste stripping mechanism 300 and the movable mold 110 need to be set to synchronous motion, so as to ensure that the raw material can be smoothly fed into the waste stripping mechanism 300 for the next step after punching.

[0023] Embodiment 1; The conveying mechanism 200 and the waste cleaning and stripping mechanism 300 are raised and lowered synchronously to ensure that the material is smoothly fed from the waste cleaning and stripping mechanism 300 to the conveying mechanism 200. Since the waste cleaning and stripping mechanism 300 moves synchronously with the movable mold 110, in order to ensure that the raw materials can be stably transported to the conveying mechanism 200 and sent out after the waste cleaning and stripping to remove the scraps, the conveying mechanism 200 must also keep synchronous movement with the waste cleaning and stripping mechanism 300. The conveying mechanism 200 in this embodiment is raised and lowered synchronously with the waste cleaning and stripping mechanism 300 through a synchronous motor.

[0024] Embodiment 2: The difference between this embodiment and embodiment 1 is that a swinging material receiving mechanism 400 is provided between the conveying mechanism 200 and the waste cleaning and peeling mechanism 300. One end of the swinging material receiving mechanism 400 is rotatably assembled with the conveying mechanism 200, and the other end is in contact with the waste cleaning and peeling mechanism 300 and always maintains a swing with the same lifting and lowering amplitude as the waste cleaning and peeling mechanism 300. In this embodiment, a swinging material receiving mechanism 400 is added to ensure that even if the waste cleaning and peeling mechanism 300 is always in a lifting motion, the finished product after waste cleaning can also be stably transported into the conveying mechanism 200 following the swinging material receiving mechanism 400.

[0025] The swinging material receiving mechanism 400 includes a plurality of synchronously swinging material receiving plates 410, one end of which is assembled with the frame of the conveying mechanism 200 through a rotating shaft or a bearing 420, and the lower pressure roller 320 is provided with a plurality of annular embedding grooves 322 corresponding to the material receiving plates 410, one end of which is placed in the embedding groove, and when the lower pressure roller 320 is upgraded, the material receiving plate 410 is driven to swing up and down relative to the rotating shaft or the bearing 420. Since one end of the material receiving plate 410 is rotatably assembled on the conveying mechanism 200, the other end of the material receiving plate 410 is placed in the annular embedding groove 322 of the lower pressure roller 320, so that one end of the material receiving plate 410 swings with the lifting and lowering of the lower pressure roller 320, while the other end of the material receiving plate 410 always maintains a fixed position, thereby ensuring that the finished product after waste removal can enter the conveying mechanism 200 along with the material receiving plate 410.

[0026] The waste stripping mechanism 300 is fixedly connected to the movable mold 110 through the fixed frame 330 to achieve synchronous lifting or lifting, or is achieved through a servo motor; the conveying mechanism 200 is synchronously lifted and lowered with the waste stripping mechanism 300 through a servo motor. The waste stripping mechanism 300 can be directly fixedly assembled with the movable mold 110 through the fixed frame 330 to achieve synchronous movement, or a servo motor can be used to achieve synchronous movement. In this embodiment, in order to reduce the manufacturing cost of the equipment, the fixed frame 330 is used to achieve synchronous movement.

[0027] The upper pressing roller 310 and the lower pressing roller 320 are driven by meshing, and the waste stripping mechanism 300 keeps the feeding speed consistent with the feeding mechanism through a servo motor or a transmission belt. The transmission structure of the upper pressing roller 310 and the lower pressing roller 320 is relatively simple, and no further elaboration is made on this.

[0028] It also includes a stripping roller 500, which cooperates with the lower pressure roller 320 to strip the waste from the material. The function of the stripping roller 500 is to separate the scraps and finished products after stripping and transport them to the waste box.

[0029] The present invention provides a waste cleaning device for a die-cutting machine. The device adds a waste cleaning and peeling mechanism. After the material is punched, the waste is peeled off from the material by pressing an upper pressure roller and a lower pressure roller along the punching lines, thereby achieving waste cleaning and peeling, improving product production efficiency and yield rate, and reducing labor input.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, simple changes and substitutions by ordinary technicians in the field are within the protection scope of the present invention.
