DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0020] See also Figure 1-3 In this embodiment, a reeling device for a paper shredder includes two wall panels 1 for placement and a cylinder bracket 2 located between the two wall panels 1. For the convenience of display, one side wall panel 1 in the attached figure of the specification is omitted.
[0021] In this embodiment, a swing arm structure is provided between the two wall panels 1, a paper roll 7 for lifting is placed on the swing arm structure, and a driving structure for pulling the swing arm structure to move is provided on the cylinder bracket 2.
[0022] In the present application, the driving structure drives the swing arm structure to swing relative to the wall panel 1, so that the paper roll 7 can be rotated and swung to lift the paper wall panel 1, thereby reducing the effort of employees in lifting the paper roll 7.
[0023] It should be noted that the swing arm structure includes a paper support 4 rotatably installed between two wall panels 1 and a paper support shaft bearing 3 fixedly installed on the wall panel 1, wherein the paper support 4 is L-shaped and has two parallel parts, between which a paper support shaft 5 for connection passes, and a reinforcing plate 16 fixedly installed for enhancing the stability of the paper support 4.
[0024] Preferably, the paper support rack rotating shaft 5 located at the right-angle end of the paper support rack 4 is rotatably connected to the paper support rack rotating shaft bearing 3 .
[0025] This design enables the paper support rack 4 to be rotated and lifted around the paper support rack rotating shaft bearing 3, and the front arm end of the paper support rack 4 is lowered to the ground position, thereby facilitating the placement of the paper roll 7.
[0026] It should be noted that a paper support slot 6 for placing the paper roll 7 is provided on the front arm end of the paper support 4, and a paper roll shaft 8 extends through the axis core of the paper roll 7, and the paper roll shaft 8 is inserted into the paper support slot 6, so that the paper support 4 can synchronously drive the paper roll 7 when it is lifted.
[0027] It can be understood that the paper support slot 6 is a right-angled trapezoid as a whole, the right-angled side of the paper support slot 6 faces the forearm end of the paper support 4, and the long oblique side of the paper support slot 6 transitions to the top of the paper support 4 to facilitate pushing the paper roll 7 to slide along the paper support slot 6.
[0028] In order to pull the paper support 4 to move, the driving structure in this embodiment includes a cylinder mounting rod connecting frame 9 fixedly mounted on the top of the cylinder bracket 2, a cylinder mounting rod 10 is rotatably mounted on the cylinder mounting rod connecting frame 9, and a cylinder 11 used as a power source is fixedly connected to the outside of the cylinder mounting rod 10;
[0029] Furthermore, a paper support push rod 12 is rotatably connected between the power rod end of the oil cylinder 11 and the paper support rotating shaft 5 at the right angle side of the paper support 4. One end of the paper support push rod 12 is fixedly connected to the power rod end of the oil cylinder 11, and the other end is rotatably connected to the paper support rotating shaft 5 in a circular ring shape.
[0030] In a specific implementation, the oil cylinder 11 is actuated to push the paper support push rod 12 to swing, thereby pushing the retirement frame 4 to rotate around the paper support rotating shaft bearing 3, and allowing the oil cylinder 11 to adapt to the angle change through the relative rotation between the oil cylinder mounting rod 10 and the oil cylinder mounting rod connecting frame 9.
[0031] In this embodiment, a paper roll placement block 15 for placing the paper roll 7 is fixedly installed on the side of the wall panel 1, and a paper roll fixing block 14 for limiting the paper roll 7 is also arranged on the top of the wall panel 1.
[0032] It should be noted that a rotating frame 13 is fixedly mounted on the top of the wall panel 1 , and one end of the paper roll fixing block 14 is rotatably connected relative to the rotating frame 13 .
[0033] A semicircular groove is provided on one side surface of the paper roll fixing block 14 for limiting the paper roll shaft 8 .
[0034] With this design, after the paper roll shaft 8 is pushed into the groove on the paper roll fixing block 14 from the side, the paper roll fixing block 14 can be rotated relative to the rotating frame 13, so that the groove on the paper roll fixing block 14 is rotated to face above the wall panel 1 to support and limit the movement of the paper roll shaft 8 relative to the wall panel 1, thereby improving the placement stability.
[0035] The working principle of the above embodiment is:
[0036] When the paper roll 7 is put into the paper holder 4, the paper roll 7 and the paper roll shaft 8 on both sides of the paper roll 7 are pushed to move along the long oblique sides of the paper roll slot 6 to abut against the two side edges of the wall panels 1. That is, the paper roll shaft 8 is directly located above the paper roll placement block 15 at this time, and the oil cylinder is controlled to retract to drive the paper holder 4 to swing down, so that the paper roll 7 can be easily placed on the paper roll placement block 15;
[0037] When it is necessary to lift the paper roll 7 above the wall panel 1, just repeat the above process, lift the paper roll shafts 8 on both sides of the paper roll 7 to the position above the wall panel 1, push them along the top of the two wall panels 1 into the lateral grooves of the paper roll fixing block 14, and then rotate the paper roll fixing block 14, so that the paper roll fixing block 14 can lift the paper roll 7 for positioning.
