Technical Field

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

[0002] Paper cutting machines use sharp blades or stamping knives to accurately and quickly cut paper. It can cut standard A4 paper or other common paper sizes, and some models can also handle larger papers.

[0003] It is retrieved that the publication number CN204622139U relates to a paper cutting machine; the paper cutting machine of the utility model includes a chassis, and also includes a support platform, a cutting component, a driving component, a feeding port and a pressing component; the driving component includes a cutting mounting disc, a connecting plate, a main cutting knife, an adjusting piece, a main support rod, a rotating plate, an auxiliary guiding rod, a transmission mounting frame, a first fixing ring and a side positioning piece; the paper cutting machine of the utility model is convenient to operate, convenient to adjust, has high cutting efficiency and good cutting effect.

[0004] However, there are still deficiencies when using CN204622139U. The cutting tool for cutting paper is exposed outside. When the cutting equipment is in use, there is no effective protection measure for the tool, and it is easy to scratch people when placing and using it, which has obvious potential safety hazards. Therefore, we propose a paper cutting machine to solve the existing problems. Content of the Utility Model

[0011] One end of the collar is provided with a pressing plate;

[0012] A protective sleeve is arranged below the pressing plate;

[0013] The inside of the protective sleeve is provided with a cutting knife;

[0014] Symmetrically distributed stroke rods are arranged at the upper end of the cutting knife, and the upper ends of the stroke rods are connected to the pressing plate;

[0015] A spring is sleeved outside the stroke rod, and a limit block is sleeved on the outer wall of the upper end of the stroke rod. The upper and lower ends of the spring are respectively connected to the limit block and the protective sleeve;

[0016] The collar and the pressing plate are equidistantly distributed. An installation block is arranged inside the collar, and an adjusting bolt is arranged at the upper end of the installation block;

[0017] A receiving groove is formed inside the upper end of the collar. An insertion block is arranged at the lower end of the installation block, and a slot is formed inside the upper end of the rotating shaft.

[0018] When using a paper cutting machine in this solution, the collar moves outside the rotating shaft. When it moves to a specified position, turn the knob at the upper end of the adjusting bolt to apply force to the adjusting bolt and the installation block. Since the lower end of the adjusting bolt and the installation block are rotationally installed through a bearing, the installation block is driven to move longitudinally, and the insertion block is inserted into the corresponding slot to adjust the spacing of the cutting tool. Grasp the handle to drive the rotating shaft to rotate. Since the collar is fixed, the pressing plate, the cutting knife and the protective sleeve are linked. After the protective sleeve is attached to the paper, it presses the cutting position. When continuing to apply pressure, the spring is stressed and contracts, and the tool descends to cut the paper on the processing table.

[0019] Preferably, a processing table is arranged inside the bracket, and the upper end of the processing table is flat.

[0020] The processing table plays a role in supporting the paper and is the loading platform for paper cutting.

[0023] Preferably, a rubber pad is arranged at the lower end of the protective sleeve.

[0024] The rubber pad prevents damage to the paper when pressing the paper. While the rubber material has anti-slip properties, it also plays a protective role for the paper.

[0025] Preferably, a stroke opening is formed inside the upper end of the protective sleeve, and the upper end of the stroke rod slidably penetrates through the stroke opening.

[0026] The stroke opening ensures the longitudinal movement of the stroke rod inside the protective sleeve.

[0027] Preferably, the internal space of the receiving groove is larger than the outer wall specification of the installation block, and the inner wall of the receiving groove is adapted to the inner wall of the installation block;

[0028] A threaded hole is arranged inside the upper end of the collar, the threaded hole penetrates through the receiving groove, and the upper end of the adjusting bolt is rotationally installed inside the threaded hole;

[0029] A torsion block is provided at the upper end of the adjusting bolt. A bearing is embedded and installed inside the upper end of the mounting block, and the lower end of the adjusting bolt is rotatably inserted into the bearing.

[0030] The storage groove functions to store the lifted mounting block. The adjusting bolt is rotatably installed inside the protective sleeve through a threaded hole. The torsion block functions as a grip when rotating the adjusting bolt. When the adjusting bolt rotates through the bearing, the mounting block is ensured to be stable.

[0031] Preferably, the lower end of the insertion block is inserted into the slot. The slots are equidistantly distributed, and the distance between the slots is 1 mm.

[0032] When the insertion block is inserted into the slot, the collar and the rotating shaft are fixed. The slots with a distance of 1 mm are used to adjust the distance between multiple cutting blades.

[0033] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0034] 1. By sleeving a protective sleeve outside the cutting blade in the present utility model, after the upper end of the protective sleeve is squeezed and pressed against the processing table, the longitudinal force squeezes out the cutting blade to cut the paper. After cutting, through the elastic contraction of the spring, the cutting tool is retracted into the protective sleeve. Before and after the paper is cut, the cutting tool is retracted, providing protection to personnel and having high use safety. BRIEF DESCRIPTION OF THE DRAWINGS
