Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a feeding mechanism and a die-cutting machine. Background Technology

[0002] Die-cutting machines are the most commonly used equipment in the packaging and printing industry. Die-cutting is one of the most frequently used processes in packaging and printing. It involves using die-cutting blades to assemble a die-cutting plate according to the product design requirements, and then cutting the printed material or other circular blanks into the required shape or cuts under pressure.

[0003] Die-cutting machines are equipped with a feed rack for conveying the film strip so that it can be die-cut by the die-cutting blade. Due to different die-cutting requirements, the desired shape or cut will vary, necessitating the replacement of the die to achieve different die-cut shapes or cuts. In existing technology, the feed rack is typically connected to the die-cutting machine via a snap-fit ​​mechanism. However, when changing the die, the feed rack must be removed from the die-cutting machine. This removal process can easily cause shaking and tilting, leading to unstable feeding. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a feeding mechanism and a die-cutting machine, which solves the problem that shaking and tilting are easily caused during the disassembly of the feeding mechanism, resulting in unstable feeding.

[0005] The technical effects to be achieved by this utility model are realized through the following aspects:

[0006] In a first aspect, this utility model provides a feeding mechanism, comprising:

[0007] The feeding assembly has a snap-fit ​​groove at its first end;

[0008] A connecting assembly includes a fixed connector and a rotating connector. The fixed connector is connected to an external die-cutting mechanism, and the rotating connector is connected to the second end of the feeding assembly, and is rotatably connected to the fixed connector.

[0009] The snap-fit ​​assembly includes a snap-fit ​​base and a snap-fit ​​component. The snap-fit ​​base is connected to an external die-cutting mechanism, and the snap-fit ​​component is rotatably connected to the snap-fit ​​base and can be snapped into the snap-fit ​​groove by rotation.

[0010] In some implementations, the connecting assembly further includes a rotating shaft, the fixed connector has a first connecting hole, the rotating connector has a second connecting hole, and the rotating shaft passes through both the second connecting hole and the first connecting hole.

[0011] In this implementation, the rotating connector and the fixed connector are respectively sleeved on the rotating shaft. The rotation of the rotating connector drives the rotating shaft to rotate relative to the fixed connector, thereby causing the feeding assembly to rotate relative to the external die-cutting mechanism.

[0012] In some implementations, the rotating connector includes a first connecting arm, a second connecting arm, and a fixing part. The first connecting arm and the second connecting arm are respectively vertically connected to two pairs of ends of the fixing part, and the second connecting holes are respectively opened at the ends of the first connecting arm and the second connecting arm away from the fixing part.

[0013] In this implementation, the first connecting arm and the second connecting arm are located at opposite ends of the fixed connector, and the rotating shaft passes through the second connecting hole of the first connecting arm, the first connecting hole of the fixed connector, and the second connecting hole of the second connecting arm, thereby making the feeding assembly rotate more smoothly and ensuring the reliability of the overall structure.

[0014] In some implementations, the first connecting arm, the second connecting arm, and the fixing part together form a frame, with a portion of the fixing connector located inside the frame.

[0015] In some implementations, the connecting assembly further includes a gasket located between the first connecting arm and / or the second connecting arm and the fixed connector. The gasket has a mounting hole, and the rotating shaft passes through the second connecting hole, the mounting hole, and the first connecting hole simultaneously.

[0016] In this implementation, the gasket avoids direct contact and wear between the fixed connector and the rotating connector, thereby extending the service life of the connecting components.

[0017] In some implementations, the rotating connector is fitted onto the second end of the surface of the feeding assembly facing away from the external die-cutting mechanism.

[0018] In some implementations, the snap-fit ​​base has a mounting groove, and one end of the snap-fit ​​component is rotatably mounted in the mounting groove.

[0019] In some implementations, the feeding assembly includes a first connecting plate, a second connecting plate, a mounting base, and a rotating roller assembly. The first connecting plate and the second connecting plate are respectively vertically connected to opposite ends of the mounting base. The opposite ends of the rotating roller assembly are respectively rotatably connected to the first connecting plate and the second connecting plate and are arranged parallel to the mounting base. The rotating connector is connected to the second end of the mounting base, and the snap-fit ​​groove is formed at the first end of the mounting base.

[0020] In some implementations, the rotating roller assembly includes multiple first rotating rollers located on a first horizontal plane and multiple second rotating rollers located on a second horizontal plane, with the multiple first rotating rollers and multiple second rotating rollers arranged alternately in parallel.

[0021] In this implementation, the first and second rotating rollers are on different horizontal planes, which plays a buffering role when conveying the film belt, avoiding the phenomenon of tension in the film belt during the conveying process, and thus ensuring the normal conveying of the film belt.

[0022] Secondly, this utility model provides a die-cutting machine, including a die-cutting mechanism and the aforementioned feeding mechanism. The die-cutting mechanism includes an upper mold and a lower mold, and a die-cutting station is formed between the upper mold and the lower mold. The die-cutting mechanism has a feeding port communicating with the die-cutting station, and the feeding mechanism is disposed at the feeding port.

[0023] In summary, this utility model has at least the following advantages:

[0024] The feeding mechanism provided by this utility model has a first end of the feeding component rotatably connected to an external die-cutting mechanism via a connecting component, and a second end of the feeding component snapped onto the die-cutting mechanism via a snap-fit ​​component. When it is necessary to change the mold of the die-cutting mechanism, the snap-fit ​​component is rotated to rotate relative to the snap-fit ​​seat, thereby disengaging from the snap-fit ​​groove of the feeding component. Then, the feeding component is rotated to move it away from the die-cutting component. This facilitates mold replacement and solves the problem that the feeding mechanism is prone to shaking and tilting during disassembly, which can lead to unstable feeding.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please see the appendix Figure 1 ~Appendix Figure 3 The feeding mechanism 10 of this utility model includes a feeding component 100, a connecting component 200, and a snap-fit ​​component 300.

[0042] In this regard, please combine Figure 1 and Figure 2 , Figure 1 and Figure 2The diagram illustrates the structural relationship between the feeding assembly 100, the connecting assembly 200, and the snap-fit ​​assembly 300 in this embodiment of the present invention. Specifically, the feeding assembly 100 has a snap-fit ​​groove 101 at its first end; the connecting assembly 200 includes a fixed connector 210 and a rotating connector 220, the fixed connector 210 being connected to the external die-cutting mechanism 20, and the rotating connector 220 being connected to the second end of the feeding assembly 100, and rotatably connected to the fixed connector 210; the snap-fit ​​assembly 300 includes a snap-fit ​​base 310 and a snap-fit ​​member 320, the snap-fit ​​base 310 being connected to the external die-cutting mechanism 20, and the snap-fit ​​member 320 being rotatably connected to the snap-fit ​​base 310, and can be snapped into the snap-fit ​​groove 101 by rotation.

[0043] In this embodiment, the fixed connector 210 of the connecting assembly 200 is connected to the external die-cutting mechanism 20, the rotating connector 220 is connected to the second end of the feeding assembly 100, and the rotating connector 220 is rotatably connected to the fixed connector 210. The snap-fit ​​seat 310 of the snap-fit ​​assembly 300 is connected to the external die-cutting mechanism 20, and the snap-fit ​​320 is rotatably connected to the snap-fit ​​seat 310. The first end of the feeding assembly 100 is provided with a snap-fit ​​groove 101. By rotating the snap-fit ​​320, the snap-fit ​​320 can be snapped into the snap-fit ​​groove 101 of the feeding assembly 100.

[0044] It is understood that by connecting component 200, the second end of feeding component 100 is rotatably connected to the external die-cutting mechanism 20, and by snap-fit ​​component 300, the first end of feeding component 100 is fixed to the die-cutting mechanism 20. Thus, when it is necessary to change the mold, simply rotate snap-fit ​​component 320 relative to snap-fit ​​seat 310, that is, snap-fit ​​component 320 disengages from snap-fit ​​groove 101 of feeding component 100, so that snap-fit ​​component 320 is released from the snap-fit ​​state. After the snap-fit ​​state is released, rotate feeding component 100 so that feeding component 100 rotates relative to external die-cutting mechanism 20 through connecting component 200, so that feeding component 100 moves away from die-cutting mechanism 20, thereby facilitating the replacement of mold in die-cutting mechanism 20. This setting method can achieve the purpose of mold replacement without disassembling the entire feeding mechanism 10, thereby avoiding the problem of shaking and tilting that is easily caused during the disassembly of feeding mechanism 10.

[0045] The feeding mechanism 10 described above has a first end of the feeding component 100 rotatably connected to the external die-cutting mechanism 20 via a connecting component 200, and a second end of the feeding component 100 snapped onto the die-cutting mechanism 20 via a snap-fit ​​component 300. When it is necessary to replace the mold of the die-cutting mechanism 20, the snap-fit ​​component 320 is rotated to rotate relative to the snap-fit ​​seat 310, thereby disengaging from the snap-fit ​​groove 101 of the feeding component 100. Then, the feeding component 100 is rotated to move away from the die-cutting component. This facilitates mold replacement and solves the problem that the feeding mechanism 10 is prone to shaking and tilting during disassembly, which can lead to unstable feeding.

[0046] In some preferred embodiments, please refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the rotating shaft 230, the rotating connector 220, and the fixed connector 210 in this embodiment of the invention. Specifically, the connecting assembly 200 further includes the rotating shaft 230, the fixed connector 210 has a first connecting hole 211, and the rotating connector 220 has a second connecting hole 221. The rotating shaft 230 passes through both the second connecting hole 221 and the first connecting hole 211. The rotating connector 220 and the fixed connector 210 are respectively sleeved on the rotating shaft 230. The rotation of the rotating connector 220 drives the rotating shaft 230 to rotate relative to the fixed connector 210, thereby causing the feeding assembly 100 to rotate relative to the external die-cutting mechanism 20. Preferably, the fixed connector 210 can be an oil-free bushing, thereby reducing friction and making the feeding assembly 100 rotate more smoothly.

[0047] In some preferred embodiments, the rotating connector 220 includes a first connecting arm 222, a second connecting arm 223, and a fixing part 224. The first connecting arm 222 and the second connecting arm 223 are respectively vertically connected to two pairs of ends of the fixing part 224. Second connecting holes 221 are respectively opened at the ends of the first connecting arm 222 and the second connecting arm 223 away from the fixing part 224. The first connecting arm 222 and the second connecting arm 223 are respectively located at opposite ends of the fixed connector 210. The rotating shaft 230 passes through the second connecting hole 221 of the first connecting arm 222, the first connecting hole 211 of the fixed connector 210, and the second connecting hole 221 of the second connecting arm 223, thereby making the feeding assembly 100 rotate more smoothly and ensuring the reliability of the overall structure.

[0048] In some preferred embodiments, the first connecting arm 222, the second connecting arm 223, and the fixing part 224 together form a frame-shaped body, with a portion of the fixing connector 210 located inside the frame-shaped body. This makes the rotating connector 220 more stable and the overall structure more compact.

[0049] In some preferred embodiments, the connecting assembly 200 further includes a gasket 240 located between the first connecting arm 222 and / or the second connecting arm 223 and the fixed connector 210. The gasket 240 has a mounting hole 241, through which the rotating shaft 230 passes simultaneously. The gasket 240 increases the contact area between the two contact surfaces, thereby effectively dispersing the pressure applied to the connection, avoiding material loss or failure due to excessive pressure. Furthermore, the gasket 240 also prevents direct contact and wear between the fixed connector 210 and the rotating connector 220, thereby extending the service life of the connecting assembly 200.

[0050] In some preferred embodiments, the rotating connector 220 is fitted onto the second end of the surface of the feeding assembly 100 facing away from the external die-cutting mechanism 20. This increases the connection area between the rotating connector 220 and the feeding assembly 100, thereby making the connection between the rotating connector 220 and the feeding assembly 100 more stable. Furthermore, it ensures that the feeding assembly 100 is fitted onto the external die-cutting mechanism 20, thus maintaining the compactness of the overall structure.

[0051] In some more preferred embodiments, the snap-fit ​​base 310 has a mounting groove 311, and one end of the snap-fit ​​member 320 is rotatably mounted in the mounting groove 311. By rotating the snap-fit ​​member 320, the snap-fit ​​member 320 is rotated along the mounting groove 311 and then snapped into the snap-fit ​​groove 101 of the feeding assembly 100, thereby fixing the feeding assembly 100 to the external die-cutting mechanism 20.

The rotating connector 220 is connected to the second end of the mounting base 113, and the snap-fit ​​groove 101 is formed at the first end of the mounting base 113.

[0055] In this embodiment, the mounting base 113 is disposed between the first connecting plate 111 and the second connecting plate 112. The rotating roller assembly 114 is arranged parallel to the mounting base 113 and its opposite ends are rotatably connected to the first connecting plate 111 and the second connecting plate 112, respectively. When feeding, the film belt passes through the rotating roller assembly 114. The rotating roller assembly 114 rotates to transport the film belt to the die-cutting mechanism 20, thereby realizing feeding.

[0056] In some preferred embodiments, the rotating roller assembly 114 includes a plurality of first rotating rollers 1141 located on a first horizontal plane and a plurality of second rotating rollers 1142 located on a second horizontal plane, with the plurality of first rotating rollers 1141 and the plurality of second rotating rollers 1142 arranged alternately in parallel. The first rotating rollers 1141 and the second rotating rollers 1142 are located on different horizontal planes, thereby providing a buffering effect during the conveying of the film belt, preventing tension during the conveying process, and ensuring the normal conveying of the film belt.

[0057] Example 3:

[0061] In this die-cutting machine, the first end of the feeding component 100 is rotatably connected to the external die-cutting mechanism 20 via the connecting component 200, and the second end of the feeding component 100 is snapped onto the die-cutting mechanism 20 via the snap-fit ​​component 300. When it is necessary to change the mold of the die-cutting mechanism 20, the snap-fit ​​component 320 is rotated to rotate relative to the snap-fit ​​seat 310, thereby disengaging from the snap-fit ​​groove 101 of the feeding component 100. Then, the feeding component 100 is rotated to move away from the die-cutting component. This facilitates mold replacement and solves the problem that shaking and tilting are easy to occur during the disassembly of the feeding mechanism 10, which can lead to unstable feeding.
