Description

Technical Field

[0001] The utility model relates to the technical field of printing and winding, in particular to printing and winding equipment. Background Art

[0002] The printing press needs to install a winding roller when performing the winding operation. The winding drum (i.e., the winding roller) in the prior art is not conveniently designed to be connected to the printing press, or the overall weight increases significantly as the winding operation proceeds. The wound soft material is very easy to loosen, which makes it very inconvenient and laborious to manually remove the winding roller.

[0003] The patent announcement number CN218619368U describes a paper printing winding device that is easy to disassemble, which is provided with an L-shaped limit support rod, a limit rod, a locking rod, a first spring, a locking hole, a positioning block, a limit hole, a second spring and a winding rotating rod. When removing the paper after winding, first push the L-shaped limit support rod to one side, and the L-shaped limit support rod drives the limit rod to move slowly in the limit slide groove, and the limit rod drives the locking rod to move, and the locking rod is pulled out of the locking hole by the buffering action of the first spring. When one end of the L-shaped limit support rod moves to the limit hole, pull the L-shaped limit support rod, and one end of the L-shaped limit support rod is inserted into the limit hole by the buffering action of the second spring. At this time, remove the winding rotating rod and remove the wound paper.

[0004] However, this device has some shortcomings when in use. During the winding operation of the winding rod, the printed paper is often exposed to dust and impurities in the air, causing wrinkles on the surface of the printed matter. In severe cases, paper jams may occur, which will cause certain damage to the motor in the winding roller. In addition, the paper jam will also block the limit slide, making it more difficult to remove the wound printed matter.

[0005] Based on this, a printing and winding device is now provided to eliminate the disadvantages of the existing devices. Utility Model Content

[0036] In this embodiment, when the sliding gear platform 602 encounters greater resistance, the spring 601 is compressed, causing the sliding gear platform 602 to move along the inner wall of the driving shaft mounting hole 503 toward the bottom of the driving shaft mounting hole 503, and the sliding gear platform 602 is retracted into the driving shaft mounting hole 503.

[0037] In one embodiment, Figure 4As shown, the sleeve includes a sleeve rod 400, and a sleeve mounting hole 401 is provided at the end of the sleeve rod 400 away from the winding rod 300, reserving space for the matching installation of the power component; the sleeve mounting hole 401 is also provided with a fixing ring 402 at the end away from the winding rod 300; a second driving shaft mounting hole 403 is opened in the fixing ring 402, and an extension rod 404 is provided at the bottom of the inner wall of the sleeve mounting hole 401, and a plurality of sliding teeth 405 distributed in a circumferential array are provided on the upper surface of the extension rod 404.

[0038] In one embodiment, Figure 2 and Figure 4 As shown, the size of the fixing ring 402 matches the matching fixing ring 502, and can jointly fix the lateral position of the driving shaft 501 with the matching fixing ring 502; the size of the second driving shaft mounting hole 403 matches the driving shaft 501, providing support for the rotation of the driving shaft 501; the sliding gear 405 matches the matching sliding gear 603, and when there is no force, the two are engaged with each other. When subjected to a certain resistance, the two are staggered and separated along the direction of the gear bevel; a limiting ring is also provided on the outside of the sleeve rod 400.

[0039] In one embodiment, Figure 5 As shown, the limiting ring includes a limiting ring platform 800 fixedly connected to the inner wall of the sleeve mounting hole 401, so that the limiting ring mounting hole 801 can be connected to the sleeve rod 400 as a whole; a limiting ring mounting hole 801 is opened in the limiting ring platform 800, and a circular groove 802 is provided on the top of the limiting ring platform 800, and a contact sensor 804 is provided on the side of the circular groove 802; a slider matching groove 803 is also provided on the top of the limiting ring platform 800.

[0040] In one embodiment, Figure 5 As shown, the size of the limit ring mounting hole 801 matches the extension rod 404, so that the limit ring mounting hole 801 can be connected to the extension rod 404 as a whole; the width of the circular ring groove 802 and the circular ring block 504 is the same, ensuring that the circular ring groove 802 and the circular ring block 504 form an annular whole when they cooperate with each other.

[0044] Working principle: When there is no paper jam, the sliding gear 405 and the matching sliding gear 603 engage with each other, and the slider 702 is stuck in the inner wall of the slider matching groove 803, so that the shaft sleeve rod 400 and the active shaft 501 move together as a whole; when a paper jam occurs, the sliding gear 405 and the matching sliding gear 603 are staggered and separated, the slider 702 compresses the second spring 701 and slides to the slider mounting groove 507, so that the shaft sleeve rod 400 and the active shaft 501 move apart. Under the rotation of the active shaft 501, the annular block 504 continues to rotate until the contact block 506 touches the contact sensor 804, interrupting the rotation of the motor 500.
