Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machine equipment structure, in particular to an eccentric wheel locking structure for a die-cutting machine. Background Art

[0002] Die-cutting machine is also called die-cutting machine, cutting machine, CNC punching machine, mainly used for die-cutting (full cutting, half cutting), creasing and hot stamping, laminating, automatic waste discharge of some corresponding non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone pads, etc. Die-cutting machine uses steel knife, hardware mold, steel wire (or template carved from steel plate), and applies a certain pressure through the stamping plate to roll and cut the printed product or cardboard into a certain shape. It is an important equipment for post-printing packaging processing;

[0003] When the existing die-cutting machine is in use, it is necessary to adjust the height distance of the rubber roller. The distance between the rubber roller and the external structure is mostly adjusted by rotating the eccentric wheel for eccentric fine-tuning. However, after the adjustment of the rubber roller is completed, the eccentric wheel used for adjustment does not have any locking structure. Therefore, in actual operation, the eccentric wheel is prone to slight rotation due to accidental touch or machine body vibration, thereby causing the adjusted distance to change, affecting the overall processing quality of the die-cutting machine.

[0020] See also Figure 1-4 The utility model provides an embodiment: an eccentric wheel locking structure of a die-cutting machine, comprising a rubber roller frame 1, a rotating shaft 2 is rotatably connected to the middle of the rubber roller frame 1 through a bearing, eccentric gears 3 are fixedly installed on the outside of the two ends of the rotating shaft 2 and located on the outside of the rubber roller frame 1, and locking gears 4 are fixedly installed on the two ends of the rotating shaft 2 and located on the inside of the rubber roller frame 1, so that when the eccentric gear 3 rotates, it can drive the locking gear 4 to rotate synchronously through the rotating shaft 2, so as to have the same rotational motion;

[0021] A rubber roller body 6 is fixedly mounted between the two sets of locking gears 4 and on the rotating shaft 2. A locking assembly 5 is provided above the two locking gears 4, so that the locking gears 4 can be engaged and locked by the provided locking assembly 5. The specific state is shown in the attached manual. Figure 4 As shown;

[0022] The locking assembly 5 is fixedly mounted on the inner wall of the side plate of the rubber roller frame 1 .

[0023] In this embodiment, in order to explain the specific structure and working principle of the locking assembly in detail, the locking assembly 5 includes a servo cylinder 501, the output end of the servo cylinder 501 is movably connected to a pneumatic rod 502, and the bottom end of the pneumatic rod 502 is fixedly installed with a rotating seat 503;

[0024] Furthermore, a locking link 504 is rotatably connected in the rotating seat 503 via a pin shaft, and one end of the locking link 504 away from the rotating seat 503 is rotatably connected to the rubber roller frame 1 via a rotating shaft;

[0025] The lower surface of the locking link 504 is provided with a locking tooth 505 adapted to the locking gear 4;

[0026] This structural design, through the set servo cylinder 501, can drive the pneumatic rod 502 to extend and retract. When the pneumatic rod 502 is extended, it will drive the rotating seat 502 at the top to extend. When the rotating seat 502 is extended and descends, the locking link 504 rotatingly connected therein will swing at a certain angle according to the rotating connection point at the other end. When the locking link 504 swings to a horizontal state, the locking tooth 505 below the locking link 504 will engage with the upper gear of the locking gear 4, so that the locking gear 4 can be locked and limited by the mutual engagement between the tooth grooves to prevent it from rotating.

[0027] Working principle: when it is necessary to lock the eccentric gear 3 after adjustment, the servo cylinder 501 of the locking assembly 5 can work, and the servo cylinder 501 can drive the pneumatic rod 502 to extend and retract. When the pneumatic rod 502 extends, it will drive the rotating seat 502 at the top to extend. When the rotating seat 502 extends and descends, the locking link 504 rotatably connected therein will swing at a certain angle according to the rotating connection point at the other end (when the pneumatic rod 502 extends, the locking link 504 will swing downward counterclockwise). When the locking link 504 swings downward to a horizontal state (as shown in the attached manual), the locking link 504 will rotate counterclockwise. Figure 4 The locking teeth 505 below the locking link 504 will engage with the upper tooth grooves of the locking gear 4, so that the locking gear 4 can be locked and limited by the mutual fit and engagement between the tooth grooves. Since the locking gear 4 and the eccentric gear 3 have the same rotational motion, when the locking gear 4 is locked, the eccentric gear 3 cannot rotate;

[0028] Through the coordinated use of the above structure, after the eccentricity of the eccentric gear 3 is adjusted, the eccentric gear 3 can be limitedly locked by the coordinated use of the locking assembly 5 and the locking gear 4, thereby effectively avoiding the eccentric gear 3 from slightly rotating due to accidental touch or body vibration during the actual operation of the die-cutting machine, effectively avoiding the adjustment spacing from changing due to external reasons, improving the overall processing quality and use safety of the die-cutting machine, having a good structural use effect, and the overall locking structure is simple, easy to use, and has a good structural use performance;

[0029] When the locking state needs to be released, the servo cylinder 501 drives the pneumatic rod 502 to retract, and the locking link 504 swings upward clockwise, and the locking tooth 505 below it disengages from the locking gear 4, thereby releasing the locking state.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
