Description

Technical Field

[0001] This utility model belongs to the field of roll paper, and in particular relates to a dual-station rotary die-cutting structure. Background Technology

[0002] A paper roll, also known as a paper tube, is a rigid cylindrical structure formed by winding and bonding paper. It has a wide range of uses in daily life and industry, such as as a support component, as a material for handicrafts, and as the inner core of a paper roll. After the paper roll is made into a paper roll, a film needs to be applied to the outer surface of the paper roll. After film application, the paper roll needs to be further cut to remove the excess parts at both ends. During the cutting process, the paper roll is usually fixed manually and then cut by a high-speed rotating cutting blade. This method is not only inefficient, but also prone to operator fatigue during long-term production, which may lead to irreversible safety accidents. In addition, the placement of the paper roll by manual fixing may not be directly aligned with the cutting station, which can easily lead to tilted cut surfaces and defective products. Furthermore, manual fixing only allows for the cutting of one section at a time, resulting in low efficiency.

[0003] For example, a Chinese utility model patent discloses a roll paper cutting machine device [application number CN201721879391.4], which includes a worktable and a spring. The worktable is provided with a groove that is slidably connected to the cutting table. The output shaft of the first cylinder is fixedly connected to the cutting table. The left side of the cutting table is provided with a second cylinder that is fixedly connected to it, and the right side of the cylinder is provided with a hinged base plate. The cutting table is provided with a cutting groove above it. The right end of the sliding plate is fixedly connected with a telescopic rod. One end of the spring is connected to the base plate, and the other end is connected to the support plate. The upper end of the motor plate is fixedly connected with a motor, and the output shaft of the motor is provided with a cutting blade. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] This embodiment provides a dual-station rotary die-cutting structure, combined with... Figure 1-4 As shown, the device includes a base 10, on which a die-cutting support rod 11 is provided. The die-cutting support rod 11 is provided with two cutting structures 12, which can move up and down along the die-cutting support rod 11. A placement cylinder 13 is provided above the base 10.

[0026] In this embodiment, the paper roll is placed on the base 10. The placement cylinder 13, under the operation of its connected upgraded driver, moves downwards so that the paper roll is fitted onto the outside of the placement cylinder 13. The clamping structure 16 fixes the paper roll to the placement cylinder 13. When the placement cylinder 13 moves downwards onto the base 10, it connects with the drive structure 15. The drive structure 15 causes the placement cylinder 13 to rotate along with the paper roll. Then, the cutting structure 12 cuts the rotating paper roll after the die-cutting support rod 11 moves to the cutting position. The placement of the paper roll can also be done by a robotic arm. The subsequent fixing and cutting steps are all completed by automated mechanical structures, eliminating the need for manual operation and improving work efficiency.

[0027] The clamping structure 16 includes a plurality of clamping grooves 17 disposed on the placement cylinder 13. The openings of the clamping grooves 17 are open.

The clamping rod 18 is connected to the driving structure. The clamping rod 18 can extend out of the clamping groove 17.

[0028] In this embodiment, when the paper roll is fixed by the placement tube 13, the clamping rod 18 extends out of the clamping groove 17 and abuts against the paper roll to support and fix the paper roll. The outer surface of the clamping rod 18 can be covered with a rubber ring, which can increase the friction between the clamping rod and the paper roll and prevent the clamping rod 18 from damaging the paper roll.

[0029] The driving structure includes a push rod 19 fixedly connected to the clamping rod 18 and slidably connected to the placement cylinder. The placement cylinder 13 has a cavity 20 inside, and a slide rod 21 is slidably arranged inside the cavity 20. The slide rod 21 is provided with a plurality of push blocks 22. The push blocks 22 are slidably connected to the inner wall of the cavity 20. The slide rod 21 extends into the cavity 20 and is slidably connected to the corresponding push block 22. The outer surface of the push block 22 connected to the push rod 19 is inclined.

[0030] In this embodiment, during the clamping of the paper roll, the slide bar 21 slides downward in the placement tube 13, causing the push block 22 to move downward. The outer surface of the push block 22 connected to the push rod 19 is inclined, causing the push rod 19 to move outward, thereby causing the clamping rod 18 to extend out of the clamping groove 17 and abut against the paper roll for fixation.

[0031] The slide rod 21 extends upward to the placement cylinder 13. The lifting block 14 is slidably provided with a drive block 23. The lifting block 14 is provided with a clamping linear actuator 24. The output shaft of the clamping linear actuator 24 is connected to the drive block 23. The slide rod 21 is rotatably connected to the drive block 23 through a rotating bearing.

[0032] In this embodiment, the sliding rod 21 is moved by the operation of the clamping linear actuator 24, and the sliding rod 21 is rotatably connected to the driving block 23 and the lifting block 14 is rotatably connected to the placement tube 13, so that the placement tube 13 can rotate with the paper roll.

[0033] The base 10 is provided with an outer groove 25, the placement cylinder 13 can extend into the outer groove 25, the bottom end of the placement cylinder 13 is provided with an inner groove 26, the drive structure 15 includes a rotating cylinder 27 that rotates in the outer groove 25, the rotating cylinder 27 is connected to the drive motor 28, and the rotating cylinder 27 can extend into the inner groove 26 to form a snap-fit ​​with the placement cylinder 13.

[0034] In this embodiment, the inner wall of the outer groove 25 can abut against the outer surface of the placement cylinder 13, and plays a supporting role during the rotation of the placement cylinder 13. During the downward movement of the placement cylinder 13, the rotating cylinder 27 can extend into the inner groove 26 and form a snap-fit ​​with the placement cylinder 13.

[0035] The drive structure 15 also includes a snap-fit ​​rod 29 slidably disposed on the rotating cylinder 27. The snap-fit ​​rod 29 extends out of the rotating cylinder 27 and is provided with a lifting spring 30 between it and the rotating cylinder 27.

[0036] In this embodiment, during the process of the placement cylinder 13 moving downward to the outer groove 15, the locking rod 29 extends into the locking groove 31. After the drive motor 28 is turned on, the locking rod 29 moves to abut against the inner wall of the locking groove 31, thereby driving the placement cylinder 13 to rotate. If the locking rod 29 does not extend into the locking groove 31 during the process of the placement cylinder 13 moving downward to the outer groove 15, the placement cylinder 13 will cause the locking rod 29 to move downward and squeeze the lifting spring 30. When the drive motor 28 is turned on and the locking rod 29 moves, when the locking rod 29 moves to the opening of the locking groove 31, the locking rod 29 extends into the locking groove 31 under the push of the lifting spring 30.

The cutting support block 32 is provided with a cutting blade 35 connected to the cutting motor 34. The cutting blade 35 extends out of the cutting support block 32 toward the placement cylinder 13.

[0038] The cutting support block 32 is provided with a displacement groove 36, and a displacement block 37 is slidably provided in the displacement groove 36. The cutting motor 34 and the cutting blade 35 are placed on the displacement block 37, and the displacement block 37 is screwed to the screw shaft 38.

[0039] In this embodiment, after the placement cylinder 13 rotates with the paper roll, the cutting support block 32 moves the cutting blade 35 to the corresponding position under the operation of the cutting lifting drive 33. Then, the screw shaft 38 rotates under the operation of the drive power supply connected to it. Through the screw connection, the displacement block 37 moves the cutting blade 35 towards the direction close to the paper roll. Under the operation of the cutting motor 34, the cutting blade 35 rotates to cut the paper roll.
