Description

Technical Field

[0001] The utility model relates to the field of die cutting, in particular to a paper feeding device of a die cutting machine. Background Art

[0002] The conveying device of the die-cutting machine usually includes a paper feeding platform and a transition platform. The paper is conveyed from the paper feeding platform to the transition platform, and then to the die-cutting mechanism. The die-cutting mechanism includes an upper mold and a lower mold. The paper will be transmitted to the lower mold. Since the die-cutting action is a continuous repetition of separation and bonding of the upper and lower molds, there will be a height difference between the lower mold and the transition platform. In this way, the paper will float during the paper feeding process, resulting in a corresponding position offset when the paper is conveyed to the lower mold. In this way, the die-cutting mold will not be aligned with the die-cutting position of the paper, resulting in defective products, which greatly affects the quality of die-cutting. Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a paper feeding device that can smoothly and accurately feed paper into the die-cutting machine on the lower mold, thereby improving the accuracy and quality of die-cutting.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a paper feeding device of a die-cutting machine, comprising an upper mold, a lower mold, a paper feeding platform and a transition platform, the upper mold and the lower mold perform opening and closing movements, an upper transmission roller and a lower transmission roller are provided at the output end of the paper feeding platform, the lower transmission roller is driven by a motor, the transition platform comprises a support platform mounted on the output side of the upper transmission roller and the lower transmission roller, a hinge is installed on the side wall in the input direction of the lower mold, a transition plate is installed at the movable end of the hinge, when the transition plate is rotated to a horizontal state, it is flush with the end face of the lower mold and fits or is close to it so that the two form an integral horizontal plane, a support shaft is installed below the end of the transition plate close to the support platform, and a plurality of arc-shaped transition steel wires arranged in sequence are also provided between the transition plate and the support platform.

[0005] One end of the arc-shaped transition steel wire is connected to the support platform, and the transition plate is provided with a yield groove corresponding to the arc-shaped transition steel wire.

[0006] A rotatable pressing roller is mounted above the end of the transition plate close to the supporting platform, and a tension spring for pulling downwards is also arranged on the transition plate.

[0007] The beneficial effect of the utility model is that after the paper is output from between the upper transmission roller and the lower transmission roller, it will pass through the support platform and then enter the transition plate through the arc-shaped transition steel wire. Since the transition plate is connected to the lower mold by a hinge, when the lower mold moves up and down, the tail end of the transition plate will swing with the lower mold, and the front end of the transition plate will swing freely against the support shaft, thus ensuring that the paper passes through the transition plate smoothly and enters the lower mold.

[0008] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 2 It is a partial cutaway view of a specific embodiment of the present utility model. DETAILED DESCRIPTION

[0011] The present invention is described in detail below through examples, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0012] like Figure 1 、 Figure 2 As shown, this embodiment discloses a paper feeding device of a die-cutting machine, comprising an upper mold 1, a lower mold 2, a paper feeding platform 3 and a transition platform 4. The upper mold 1 and the lower mold 2 perform opening and closing movements. An upper transmission roller 5 and a lower transmission roller 6 are provided at the output end of the paper feeding platform 3. The lower transmission roller 6 is driven by a motor. The transition platform 4 comprises a support platform 7 mounted on the output side of the upper transmission roller 5 and the lower transmission roller. A hinge 8 is installed on the side wall in the input direction of the lower mold 2. A transition plate 9 is installed at the movable end of the hinge 8. When the transition plate 9 is rotated to a horizontal state, it is flush with the end face of the lower mold 2 and fits or approaches the end face of the lower mold 2 to form an integral horizontal plane. A support shaft 40 is installed below the end of the transition plate 9 close to the support platform. A plurality of arc-shaped transition steel wires 10 arranged in sequence are also provided between the transition plate 9 and the support platform 7. In this way, the interval between the transition plate 9 and the support platform 7 changes during the swinging process, and the transition connection is performed through the arc-shaped transition steel wire 10, so that the paper can smoothly enter the transition plate 9.

[0013] One end of the curved transition wire 10 is connected (welded) to the support 7. The transition plate 9 is provided with a clearance groove corresponding to the curved transition wire 10. During the swinging process of the transition plate 9 along the hinge 8, one side of the curved transition wire 10 is always in the clearance groove. The installation of the curved transition wire 10 in this way makes the structure more reliable.

[0014] A rotatable pressure roller 20 is mounted above the end of the transition plate 9 near the support platform. A swing plate is located on either side of the paper feed platform 3, with the pressure roller mounted at the end of each swing plate. A tension spring 30 is also installed on the transition plate 9 to pull downward. This structure ensures that the pressure roller 20 ensures that paper passing through the transition plate 9 always adheres to the transition plate 9, further improving the reliability of paper passage. The tension spring 30 ensures that the transition plate 9 maintains contact with the support shaft 40, preventing the transition plate 9 from bouncing during high-speed die-cutting operations, which could affect paper feed accuracy.

[0015] With the above technical solution, after the paper is output from between the upper transmission roller 5 and the lower transmission roller 6, it will pass through the support platform 7, and then enter the transition plate 9 through the arc-shaped transition steel wire 10. Since the transition plate 9 is connected to the lower mold 2 through the hinge 8, when the lower mold 2 moves up and down, the tail end of the transition plate 9 will swing with the lower mold 2, and the front end of the transition plate 9 will lean against the support shaft 40 and swing freely, thus ensuring that the paper passes through the transition plate 9 smoothly and smoothly into the lower mold 2.

[0016] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
