[0012] The slide table is slidably mounted on the frame, with the sliding direction perpendicular to the guide roller, and is used to adjust the distance between the winding shaft and the cutting mechanism.

[0013] Furthermore,

[0014] The take-up shaft is connected to the base plate via a turntable, and includes a support portion fixedly mounted on the turntable and a movable portion slidably mounted on the turntable;

[0015] The turntable is rotatably mounted on the base plate and is used to drive the take-up shaft to rotate;

[0016] The cross-sectional structure of the support part and the movable part is the same, both being semi-circular.

[0017] Furthermore,

[0018] The movable part is located above the support part and is driven by the support part through a drive cylinder;

[0019] The cylinder body of the drive cylinder is fixedly mounted on the movable part and connected to the support part through the piston rod.

[0020] Furthermore,

[0021] The support part is also provided with a retractable pressing part for pressing the decorative paper onto the movable part;

Detailed Implementation

[0046] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0047] Please refer to Figure 1-3 This embodiment provides a cutting device for printed decorative paper, including a frame 100, on which guide rollers 110 and drive rollers 120 are respectively provided parallel to each other; a cutting mechanism, located on the side of the drive rollers 120 away from the guide rollers 110, including a slide 200 and a cutter 210 mounted on the slide 200; the slide 200 is slidably mounted on the frame 100, and the sliding direction is parallel to the axial direction of the guide rollers 110, for driving the cutter 210 to cut the decorative paper; and a winding mechanism, located on the side of the cutting mechanism away from the drive rollers 120. One side includes a base plate 300 movably mounted on the frame 100 and a take-up shaft 310 rotatably mounted on the base plate 300; the number of take-up shafts 310 includes two, located at both ends of the base plate 300 respectively, and each has a radially extending insertion interface corresponding to the decorative paper; the base plate 300 is connected to the frame 100 via a slide table 320 and is rotatably connected to the slide table 320 for switching the positions of the two take-up shafts 310; the slide table 320 is slidably mounted on the frame 100, and the sliding direction is perpendicular to the guide roller 110 for adjusting the distance between the take-up shaft 310 and the cutting mechanism.

[0048] In this embodiment, the frame 100 extends along a first direction, and a guide roller 110 is provided at one end to allow the decorative paper to extend along a specified path on the frame 100. A drive roller 120 is provided to provide driving force to the decorative paper.

[0049] In this embodiment, the slide table 320 is slidably mounted on the frame 100, and the sliding direction is parallel to the first direction; the middle part of the substrate 300 is rotatably connected to the slide table 320 through a rotating shaft, and the rotating shaft is also connected to the corresponding motor drive; the take-up shaft 310 is correspondingly mounted at both ends of the substrate 300, and can rotate relative to the substrate 300. When the decorative paper is connected to the insertion interface on the take-up shaft 310, the decorative paper can be rolled up by rotation; at the same time, during the rotation of the take-up shaft 310, the slide table 320 also synchronously drives the substrate 300 away from the switching mechanism, so that the decorative paper roll will not be disturbed by the frame 100 due to the increase in diameter.

[0050] In a preferred embodiment, the take-up shaft 310 is connected to the substrate 300 via a turntable 330, and includes a support portion 331 fixedly mounted on the turntable 330 and a movable portion 332 slidably mounted on the turntable 330; the turntable 330 is rotatably mounted on the substrate 300 and is used to drive the take-up shaft 310 to rotate; the support portion 331 and the movable portion 332 have the same cross-sectional structure, both being semi-circular.

[0051] In this embodiment, the take-up shaft 310 is rotatably connected to the substrate 300 via the turntable 330, thereby realizing relative rotation between the take-up shaft and the substrate 300; at the same time, the substrate 300 is also provided with a corresponding motor, which can drive the turntable 330 to perform corresponding rotation.

[0052] In this embodiment, the winding shaft 310 includes two parts: a support part 331 and a movable part 332. Both parts have semi-circular cross sections, and the gap between them forms an insertion interface.

[0053] In a preferred embodiment, the movable part 332 is located above the support part 331 and is driven to the support part 331 via a drive cylinder 333; the cylinder body of the drive cylinder 333 is fixedly mounted on the movable part 332 and is connected to the support part 331 via a piston rod.

[0054] In this embodiment, the cylinder body of the drive cylinder 333 is fixedly installed on the side of the movable part 332 away from the support part 331, and the piston rod is connected to the support part 331 by passing through the movable part 332.

[0055] In a preferred embodiment, the support portion 331 is further provided with a retractable pressing portion 334 for pressing the decorative paper onto the movable portion 332; the number of pressing portions 334 includes a plurality of them, which are evenly arranged along the extending direction of the support portion 331.

[0056] In this embodiment, the pressing part 334 is telescopically mounted on the support part 331. When it is in the retracted state, the pressing part 334 can be completely retracted into the interior of the support part 331. When it is in the extended state, the top of the pressing part 334 can abut against the movable part 332, thereby pressing the decorative paper onto the movable part 332 and providing support for the movable part 332, thereby improving the stability of the winding shaft 310.

[0057] In this embodiment, during the rolling process, the end of the decorative paper is first inserted into the insertion interface, and then pressed by the pressing part 334. The paper can then be rolled by the rotation of the take-up shaft 310. After the paper is rolled, the pressing part 334 is first retracted into the support part 331, and then the movable part 332 is driven to move towards the support part 331, so that the decorative paper roll can easily be released from the take-up shaft 310.

[0058] In a preferred embodiment, the interior of the support portion 331 is provided with a drive assembly corresponding to the pressing portion 334; the drive assembly includes a lead screw 335 rotatably mounted on the support portion 331 and a sliding sleeve 336 sleeved on the lead screw 335; the sliding sleeve 336 and the pressing portion 334 are connected by an inclined plane, which is used to drive the pressing portion 334 to rise and fall relative to each other.

[0059] In this embodiment, the support part 331 has a cavity along the axial direction inside, and a sliding sleeve 334 with the same cross section and relatively short length is provided in the cavity; the top of the support part 331 has a stepped hole communicating with the cavity for installing the clamping part 334; the size of the stepped hole near the cavity is relatively large; the cross section of the clamping part 334 is inverted T-shaped, so that it can be raised and lowered relative to the support part 331 without detaching from the support part 331.

[0060] In this embodiment, the clamping part 334 and the sliding sleeve 336 are connected by an inclined face, so the clamping part 334 can be effectively driven to extend and retract by driving the sliding sleeve 336 to slide; the sliding sleeve 336 and the lead screw 335 are connected by a thread. Since the cavity restricts the rotation of the sliding sleeve 336, the sliding sleeve 336 can be effectively driven to slide relative to each other by rotating the lead screw 335.

[0061] In this embodiment, the lead screw 335 is driven by a stepper motor. The stepper motor is fixedly mounted on the support 331, and its output end is connected to the lead screw 335 through a worm gear mechanism, so that it can not only drive the lead screw 335 to rotate, but also form a self-locking mechanism for the lead screw 335.

[0062] In a preferred embodiment, the frame 100 is further provided with an auxiliary roller 400; the auxiliary roller 400 is located between the cutting mechanism and the rolling mechanism, and there are two of them arranged vertically; the auxiliary roller 400 can rotate relative to the frame 100, and its extension direction is parallel to the drive roller 120.

[0063] In this embodiment, the auxiliary roller 400 is located between the cutting mechanism and the rolling mechanism. The cut end of the decorative paper can form a new position by entering between the two auxiliary rollers 400, which makes it easier to connect with the insertion interface.

[0064] In a preferred embodiment, any one of the auxiliary rollers 400 is driven by a first motor; the two auxiliary rollers 400 abut against each other to clamp and drive the decorative paper.

[0065] In a preferred embodiment, the number of guide rollers 110 includes two, which are rotatably connected to the frame 100 respectively; the two guide rollers 110 are arranged vertically and staggered, with the upper guide roller 110 being relatively close to the drive roller 120.

[0066] In a preferred embodiment, the number of drive rollers 120 includes two, arranged vertically and abutting each other; either drive roller 120 is driven by a second motor to press and drive the decorative paper.
