Description

Technical Field

[0001] The utility model belongs to the field of cutting machines, in particular to a printing paper cutting machine. Background Art

[0002] The main function of the paper cutter is to slit and rewind wide webs into rolls of varying widths and diameters.

[0003] In the cutting process, a friction roller is required to use friction to drive the paper forward to achieve automatic cutting. In addition, the paper to be cut is rolled up and stored on the storage roller. This storage roller does not require an additional driving mechanism. The friction roller can pull the paper to make it rotate. Figure 1 shown.

[0004] However, no matter how the storage roller is rotatably connected to the bracket, it is difficult to separate it from the bracket, which results in that after the paper on the storage roller is cut, either the bracket is removed and the storage roller with the paper roll is reinstalled, or the storage roller and the bracket are replaced together, which seriously affects the cutting progress. Utility Model Content

[0005] Technical problem to be solved: How to replace the take-up roller on which the cut roll paper relies.

[0006] Technical solution: The utility model provides a printing paper cutting machine, including a main component and a split component: the main component includes a base plate, two vertical frames are symmetrically connected to the top of the base plate, and the vertical frames are rotatably connected to a horizontal shaft rod through bearings, and a storage roller is arranged between the two shaft rods, and the storage roller is a solid structure; the split component includes a clamping mechanism arranged between the shaft rod and the storage roller for clamping the storage roller in the longitudinal direction, and the clamping mechanism includes a rectangular block connected to the inner side of the shaft rod; at the same time, it also includes rectangular grooves that are opened on both sides of the storage roller and are adapted to the rectangular block; at the same time, it also includes a horizontal slide groove opened on the top of the base plate, and one of the vertical frames is slidably connected to the base plate through the slide groove; in addition, a driving mechanism for driving the vertical frame to move horizontally along the slide groove is also arranged on the base plate.

[0007] Furthermore, the driving mechanism comprises a sleeve with an internal thread fixed on the inner side of the vertical frame, a screw rod is cooperatively connected in the sleeve, and the end of the screw rod is cooperatively connected to a bearing seat fixed on the inner side of another vertical frame.

[0008] Furthermore, the bearing seat includes a shell and a bearing, the outer wall of the shell is fixedly connected to the inner side of the corresponding vertical frame, the inner wall of the shell is fixedly connected to the outer ring of the bearing, and the inner ring of the shell is interference fit with the screw rod.

[0009] Furthermore, a handle is fixedly sleeved on the outer peripheral side of the screw rod.

[0010] Furthermore, a sliding block is slidably connected in the sliding groove, and the sliding block is fixed at the bottom end of the corresponding vertical frame.

[0011] Furthermore, two telescopic rods which are freely telescopic and symmetrical about the sleeve can be fixedly connected between the two vertical frames, and the telescopic rods are used to further restrict the rotation of the movable vertical frames.

[0012] Technical effect: In the utility model, since the locking mechanism locks the storage roller in the longitudinal direction, it is separable in the transverse direction. On this basis, the corresponding vertical frame is moved away from the other vertical frame along the slide groove through the action of the driving mechanism, so that the distance between the two shafts can be increased. In this way, the locking of the storage roller in the longitudinal direction will disappear and it can be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0019] The printing paper cutting machine provided in this specific embodiment is as follows: Figure 2 and Figure 3 As shown, it includes main components and sub-components, among which:

[0020] The main body comprises a bottom plate 1, two vertical frames 2 are symmetrically connected to the top of the bottom plate 1, and the vertical frames 2 are rotatably connected to a horizontal shaft 3 through a bearing, and a storage roller 4 is arranged between the two shafts 3. The storage roller 4 is a solid structure. In order to reduce weight, the storage roller 4 can be made of hard plastic.

[0021] The split component includes a clamping mechanism 5 arranged between the shaft 3 and the receiving roller 4 for clamping the receiving roller 4 in the longitudinal direction, such as Figure 3 As shown, the engaging mechanism 5 includes a rectangular block 501 connected to the inner side of the shaft 3; at the same time, it also includes a rectangular groove 502 adapted to the rectangular block 501 and opened on both sides of the storage roller 4; at the same time, it also includes a transverse slide groove 6 opened at the top of the bottom plate 1, and one of the vertical frames 2 is slidably connected to the bottom plate 1 through the slide groove 6. Specifically, a slider 9 is slidably connected in the slide groove 6, and the slider 9 is fixed to the bottom end of the corresponding vertical frame 2; in addition, a driving mechanism 7 for driving the vertical frame 2 to move horizontally along the slide groove 6 is also provided on the bottom plate 1, as shown in FIG. Figure 3 As shown, the driving mechanism 7 includes a sleeve 701 with an internal thread fixed on the inner side of the vertical frame 2, a screw rod 702 is connected in the sleeve 701, and the end of the screw rod 702 is connected in the bearing seat 703 fixed on the inner side of another vertical frame 2. In this way, by rotating the screw rod 702, the corresponding vertical frame 2 is away from the other vertical frame 2, so that the distance between the two shafts 3 can be increased, so that the rectangular block 501 is separated from the rectangular groove 502, so that the storage roller 4 can be easily removed for replacement. It is worth mentioning that because the corresponding vertical frame 2 is restricted from rotating by the slide groove 6 and the slider 9, this vertical frame 2 can only move along the slide groove 6.

[0022] In addition to the above:

[0023] 1. Regarding the bearing seat 703, specifically, the bearing seat 703 includes a shell and a bearing, the outer wall of the shell is fixedly connected to the inner side of the corresponding vertical frame 2, the inner wall thereof is fixedly connected to the outer ring of the bearing, and the inner ring thereof is interference fit with the screw rod 702.

[0024] Second, such as Figure 3 As shown, a handle 8 can be fixedly sleeved on the outer peripheral side of the screw rod 702 to facilitate rotation.

[0025] Third, two freely retractable telescopic rods symmetrical about the sleeve 701 can be fixedly connected between the two vertical frames 2. The telescopic rods are used to further limit the rotation of the movable vertical frame 2, so that when the screw rod 702 rotates, the vertical frame 2 can stably move along the slide groove 6.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
