Description

Technical Field

[0001] The utility model relates to a die cutting machine, in particular to a material clamping mechanism of a die cutting machine. Background Art

[0002] A die cutting machine, also called a beer machine, a cutting machine, and a numerical control punching machine, is mainly used for die cutting (full cut, half cut), indentation, hot stamping, laminating, and automatic waste discharging of some non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, mobile phone gaskets, etc. The die cutting machine uses steel knives, metal molds, steel wires (or templates engraved from steel plates), and applies a certain pressure through an impression plate to cut the printed matter or cardboard into a certain shape. It is an important device for post-printing packaging processing and forming. When the drum of a traditional die cutting machine is in use, it needs to move up and down or back and forth. However, limited by its own volume, large mass, and the obstruction of the drive interlock structure, it is necessary to move and adjust the whole part locally, which is time-consuming and laborious and very inconvenient. Content of the Utility Model

[0003] Aiming at the existing technical deficiencies, the utility model provides a material clamping mechanism of a die cutting machine.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a material clamping mechanism of a die cutting machine, including a cylinder body, and further including a frame, a main shaft and a guide rail running across the frame. A force arm connecting the cylinder body is sleeved on the main shaft. A base in sliding fit is arranged on the guide rail. A telescopic rod movably connected to the force arm is arranged on the side wall of the base. A swing arm and a swing seat are respectively arranged between the base and the force arm. The swing arm is hinged to the base. The swing seat is fixedly assembled with the force arm. A chute arranged along an arc path is arranged on the swing seat. A sliding part slidably matched with the chute is arranged on the swing arm.

[0005] A fastener passing through the chute is inserted on the sliding part.

[0006] A slot for inserting the sliding part is arranged in the center of the swing seat.

[0007] The telescopic rod is a hydraulic rod, and the two ends of the telescopic rod are respectively hinged to the base and the force arm.

[0008] A connecting part is arranged on the force arm. The force arms are arranged in pairs, and the force arms are connected into a whole through the connecting part and a shaft.

[0009] The beneficial effect of the utility model: The material clamping mechanism of the die cutting machine provided by the utility model adopts a multi-connected support structure. Flexible force arms are installed on both sides of the drum at the same time, and the force arms are closely connected. It is safe, reliable and stable in use, and meets the design and use requirements. Description of the Drawings

[0012] Figure 3 It is a partial enlarged structural schematic diagram of the present utility model. Specific embodiments

[0013] As Figures 1 - 3 shown, a material clamping mechanism of a die - cutting machine includes a cylinder body, and also includes a frame 1, a main shaft 2 and a guide rail 3 running across the frame 1. The main shaft 2 and the guide rail 3 are arranged parallel in the same direction, mainly for adjusting the relative horizontal position of the cylinder body. A force arm 4 connecting the cylinder body is sleeved on the main shaft 2. A base 5 with a sliding fit is provided on the guide rail 3. An expansion rod 6 movably connecting the force arm 4 is provided on the side wall of the base 5. A swing arm 7 and a swing seat 8 are respectively provided between the base 5 and the force arm 4. The swing arm 7 is hinged to the base 5. The swing seat 8 is fixedly assembled with the force arm 4. A chute 9 arranged along an arc path is provided on the swing seat 8. The swing arm 7 has a sliding part 10 slidably matched with the chute 9. The force arm 4 is connected to the main shaft 2, but its load - bearing point is concentrated at the connection with the expansion rod 6, or in other words, it relies on the expansion rod 6 to provide corresponding support force. The swing arm 7 and the swing seat 8 are designed in a sliding - fit form to adapt to the rotation action of the force arm 4, and the size design of the chute 9, that is, the central angle of the path, should be limited within a certain range to prevent the force arm 4 from moving beyond an excessive range.

[0014] A fastener 11 passing through the chute 9 is inserted into the sliding part 10. The fastening direction of the fastener 11 is different from the main force - bearing direction, and the two are perpendicular, hardly affecting the detachment of the force arm 4. The swing seat 8 is provided with a slot 12 in the center for inserting the sliding part 10, weakening the influence of relative left - right movement on the connection of the swing arm 7, further ensuring the use of the fastener 11, and also avoiding the risk of tipping in case of emergencies. The expansion rod 6 is a hydraulic rod, and both ends of the expansion rod 6 are respectively hinged to the base 5 and the force arm 4. The hydraulic rod is a mature technical means, which can provide a large support force and meet the design and use requirements. Both ends of the expansion rod 6 are movably connected, without affecting its jacking up of the force arm 4 during telescoping. The force arm 4 has a connecting part 13. The force arms 4 are arranged in pairs, and the force arms 4 are connected into one body through the connecting part 13 and a shaft. The force arms 4 are connected into one body, avoiding serious consequences caused by damage or failure at one place, and being beneficial to reducing the safety - use risk.

[0015] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
