Description

Technical Field

[0001] This utility model relates to the field of unwinding devices, specifically to an unwinding device for a printing press. Background Technology

[0002] In printing processing, an unwinding device is installed at the feeding end of the printing press to support the rolled material and provide a continuous and stable supply of material to the printing press. For example, patent document CN222630587U discloses an unwinding device. When the roll material needs to be loaded, the unwinding device removes the support bar to change to a state where the rotating sleeve is not supported, which facilitates loading. After the roll material is placed on the rotating sleeve, the support bar is reset so that it is located below the front end of the rotating sleeve again. The front end of the rotating sleeve is supported in place by a height-adjustable arc-shaped support block to prevent it from having too much jumping space during the unwinding process.

[0003] However, the material rollers used to support the material in the current unwinding device are quite high. When the weight of the rolled material is large, the operator needs to spend a lot of labor to move the rolled material and then use other height-increasing equipment, which reduces the effectiveness of the unwinding rack.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses an unwinding device for a printing press.

[0028] This utility model provides, for example Figure 1-4 The unwinding device of the printing machine shown includes a printing machine 1 and an unwinding frame 2. A support shaft 3 is rotatably passed through the upper end of the inner wall of the unwinding frame 2. A guide plate 4 is fixedly sleeved on the shaft wall of the support shaft 3. A groove is opened at the lower end of the inner wall of the guide plate 4. A baffle 5 is contacted on the inner wall of the groove.

[0029] Both ends of the top of the unwinding frame 2 are fixedly provided with locking rods 6. The upper end of the locking rod 6 is slidably fitted with a stop block 7. The rod wall of the locking rod 6 is fitted with a spring 8. The two ends of the spring 8 are fixedly connected to the locking rod 6 and the stop block 7 respectively.

[0030] Both ends of the support shaft 3 are provided with a feeding mechanism for driving the guide plate 4 to rotate. The feeding mechanism includes a drive motor 9. The lower ends of both sides of the outer wall of the unwinding frame 2 are fixedly provided with a base plate 10. The worm gear 11 is rotatably inserted inside the two base plates 10. The upper end of the worm gear 11 is fitted with a worm wheel 12. The worm wheel 12 is fixedly connected to the support shaft 3. The drive motor 9 is fixedly installed at the bottom of the unwinding frame 2, and the output shaft is fixedly connected to the bottom of one side of the worm gear 11. The upper ends of both sides of the outer wall of the unwinding frame 2 are fixedly provided with a support cylinder 15. The worm gear 11 is rotatably inserted into the support cylinder 15.

[0031] Both worm gears 11 have a timing pulley 13 fixedly fitted at their lower ends, and a timing belt 14 is provided on the outer side of the timing pulley 13 for transmission.

[0032] To ensure the stability of the coil material as it moves onto the guide plate 4 and inside the clamping rod 6, such as Figure 1 and Figure 3-4 As shown, side limiting plates 18 are fixedly provided on both sides of the guide plate 4, the lower end of the side wall of the stop block 7 is set with an inclined surface, the inner wall of the groove is fixedly provided with a support rod 16, the baffle 5 is rotatably sleeved on the outside of the support rod 16 and in contact with the inner wall of the groove, the rod wall of the support rod 16 is sleeved with a torsion spring 17, and the two ends of the torsion spring 17 are fixedly connected to the support rod 16 and the baffle 5 respectively.

[0033] Working principle: When in use, place the roll material on the ground and align it with the bottom of the guide plate 4. Push the roll material to push the baffle 5. At this time, the baffle 5 rotates around the support rod 16 and twists the torsion spring 17. When the roll material moves to the top of the bottom of the guide plate 4, the torque of the torsion spring 17 returns, and the baffle 5 rotates to restrict the roll material on the inner wall of the mating groove. At this time, both ends of the roll material are also supported by the side limiting plate 18.

[0034] Subsequently, the drive motor 9 is started, and its output shaft drives the worm gear 11 on one side to rotate. The synchronous pulley 13 and the synchronous belt 14 make the worm gears 11 on both sides rotate synchronously. The worm gear 11 drives the worm wheel 12 and the support shaft 3 to rotate, thereby driving the guide plate 4 to rotate. The roll material rises with the guide plate 4 to the height of the printing machine 1 feed port, and the side limit plate 18 keeps the roll material conveying stable.

[0035] As the guide plate 4 rotates, the roll material falls under its own weight and begins to contact the inclined surface of the stop block 7. At this time, the stop block 7 is pushed and slides up the clamping rod 6 to compress the spring 8, causing one side of the clamping rod 6 to open. When the roll material enters the interior of the clamping rod 6, the spring 8 returns and causes the stop block 7 to limit the outer side of the roll material, so that the roll material can rotate stably and cooperate with the printing machine to perform feeding and printing work.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
