Description

Technical Field

[0001] This utility model relates to the field of paper cutting mechanism technology, specifically a paper cutting mechanism for a household paper cutting device. Background Technology

[0002] Most existing paper cutting equipment for household paper uses a cutting mechanism consisting of two parts: a fixed blade shaft and a rotatable folding roller. The fixed blade shaft is equipped with an upper cutting blade, while the folding roller typically has three bottom cutting blades. Traditionally, both the upper cutting blade on the fixed blade shaft and the bottom cutting blades on the folding roller are straight blades.

[0003] An existing patent (publication number CN203650578U) discloses a paper cutting mechanism for a household paper cutting device. It adopts a spiral arc-shaped blade holder that is detachably connected to a fixed blade shaft. This not only effectively solves the problem of multiple blade contact and collision caused by inconsistent spacing between the upper and lower blades, but also ensures the machining accuracy of the spiral arc surface of the blade holder through the machining positioning strip provided on the spiral arc-shaped blade holder. At the same time, the fine-tuning device provided in the cutting mechanism can solve the problem of blade deviation during debugging, testing, and production, further ensuring the rationality and reliability of the paper cutting mechanism.

[0004] However, some problems exist in the use of existing paper cutting mechanisms: 1. The dimensions of existing paper cutting mechanisms are fixed, making it impossible to quickly change and adjust them according to the required cutting size, thus affecting the versatility of the paper cutting mechanism. 2. Existing household paper is often cut horizontally, making it impossible to cut round paper, which affects the cutting effect of the paper cutting mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a paper cutting mechanism for a paper cutting device for household paper, so as to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: including a side column, wherein a lifting component for efficient height adjustment is installed inside the side column, a rotating component for efficient operation is installed at the upper end of the lifting component, a connecting column is connected at the lower end of the rotating component, and a replacement component for individual disassembly or installation of the component is installed at the lower end of the connecting column.

[0007] The lifting assembly includes a limiting groove, a rod is installed inside the limiting groove, a horizontal plate is fitted on the side wall of the rod, and through holes are opened on both sides of the horizontal plate;

[0008] The rotating assembly includes a first gear, and a second gear that cooperates with the first gear is mounted on the upper end of the right horizontal plate of the first gear.

[0011] As a further embodiment of this utility model: a support plate is installed on the upper end of the second gear, and a second motor is installed on the upper end of the support plate and connected to the second gear at the lower end.

[0012] As a further improvement of this utility model, a tube cutter is fitted onto the lower end surface of the insert.

[0013] As a further improvement of this utility model: the inner wall of the perforation at the left end of the horizontal plate is provided with threads that mesh with the outer wall of the rod at the left end of the horizontal plate.

[0014] As a further improvement of this utility model, the size of the insertion post is the same as the size of the slot.

[0015] As a further improvement of this utility model, the cross-sectional dimensions of the limiting groove are matched with the cross-sectional dimensions of the horizontal plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0023] To facilitate the solution of the problem, this utility model provides a paper cutting mechanism for a household paper cutting device. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] like Figures 1 to 3 As shown, this embodiment provides a paper cutting mechanism for a household paper cutting device, including a side column 1. A lifting component for efficient height adjustment is installed inside the side column 1. A rotating component for efficient operation is installed at the upper end of the lifting component. A connecting column 4 is connected to the lower end of the rotating component. A replacement component for disassembling or installing the component is installed at the lower end of the connecting column 4.

[0026] The lifting assembly includes a limiting groove 201, a rod 202 is installed inside the limiting groove 201, a horizontal plate 204 is fitted on the side wall of the rod 202, and through holes 205 are opened on both sides of the horizontal plate 204.

[0027] The rotating assembly includes a first gear 301, and a second gear 302 that cooperates with the first gear 301 is installed on the upper end of the right horizontal plate 204 of the first gear 301.

[0028] The replacement component includes a slot 501, in which a post 502 is detachably inserted. The post 502 has a first threaded groove 503 on both sides, and the slot 501 has a second threaded groove 504 on both sides. Bolts 505 are installed inside the first threaded groove 503 and the second threaded groove 504.

[0029] Furthermore, the upper end of the left side rod 202 of the horizontal plate 204 is connected to a first motor 203. When the rod 202 rotates, the threads on the outer wall mesh with the internal threads of the through hole 205, and the horizontal plate 204 moves downward under the limiting groove 201.

[0030] Furthermore, a support plate 303 is installed on the upper end of the second gear 302. A second motor 304 is installed on the upper end of the support plate 303 and connected to the second gear 302 at the lower end. The operation of the second motor 304 drives the second gear 302 to rotate, which in turn drives the first gear 301 to rotate through the meshing of the side wall tooth blocks.

[0031] Furthermore, a tube cutter 506 is fitted onto the lower surface of the insert post 502. Pulling the tube cutter 506 downward causes the insert post 502 at its upper end to disengage from the slot 501, allowing the tube cutter 506 to be replaced with one of the required dimensions for the tissue paper being cut.

[0032] As a further embodiment of this utility model: the inner wall of the perforation 205 at the left end of the horizontal plate 204 is provided with threads that mesh with the outer wall of the rod 202 at the left end of the horizontal plate 204. The threads on the outer wall mesh with the threads in the perforation 205, and under the limitation of the limiting groove 201, the horizontal plate 204 is driven to move downward, which quickly drives the cutting component at the lower end to rotate and cut.

[0033] As a further improvement of this utility model: the size of the insert 502 is the same as the size of the slot 501, and the tube knife 506 is pulled down so that the insert 502 at its upper end is disengaged from the slot 501.

[0034] Furthermore, the cross-sectional dimensions of the limiting groove 201 are matched with the cross-sectional dimensions of the horizontal plate 204, and the horizontal plate 204 moves downward under the limiting of the limiting groove 201.

[0035] Working principle: By twisting the bolt 505 outward, it engages with the first screw groove 503 and the second screw groove 504 to remove it. Pull the tube blade 506 downward so that the upper insert 502 disengages from the slot 501. Replace the tube blade 506 with one of the required dimensions for the tissue paper being cut. Insert the replaced insert 502 into the slot 501. Engage the bolt 505 and align it with the first screw groove 503 and the second screw groove 504 to complete the replacement of the cutting component. Control the second motor 304 to drive the second gear 302 to rotate. Through the engagement of the side wall teeth, the first gear 301 is driven to rotate, thereby driving the lower connecting column 4 to rotate. At the same time, control the first motor 203 to drive the lower rod 202 to rotate. Through the engagement of the thread on the outer wall with the thread in the through hole 205, the horizontal plate 204 moves downward under the limit of the limiting groove 201, quickly driving the lower cutting component to rotate and cut.
