Technical Field
[0001] The utility model relates to the technical field of guillotine-type paper cutters, in particular to a guillotine-type paper cutter. Background Art
[0002] A guillotine paper cutter is a common mechanical device used to cut paper and other similar materials. It uses a vertically moving blade (guillotine) to perform the cuts. It is commonly used in industries such as printing, papermaking, and packaging. This type of guillotine paper cutter is particularly useful for notebook production.
[0003] When an existing guillotine-type paper cutter cuts stacked papers, in order to improve cutting efficiency, multiple sheets of paper are overlapped for cutting. The pressure exerted by the guillotine on the paper cutting position causes the stacked papers to deform. This deformation can easily cause the position of the folded papers to shift, resulting in misalignment of the cut folded papers and easily causing paper cutting errors.
[0004] Therefore, it is necessary to design a guillotine paper cutter to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0018] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0019] See also Figure 1-3 The utility model provides a guillotine paper cutter, comprising a chassis 1, a side plate 2 being fixedly connected to one side of the chassis 1, a slide groove 6 being provided on one side of the side plate 2, a motor 3 being fixedly connected to the top of the side plate 2, a screw 5 being fixedly connected to the output shaft of the motor 3, a threaded connecting plate 4 being threadedly sleeved on the outer surface of the screw 5, and a lifting cylinder 7 being fixedly connected to one side of the threaded connecting plate 4, two symmetrical springs 19 being fixedly connected to the top of the inner cavity of the lifting cylinder 7, and an insert block 20 being fixedly connected to the bottom of the two springs 19, and a pressure block 21 being fixedly connected to the bottom of the insert block 20, a connecting block 8 being fixedly connected to one side of the lifting cylinder 7, and the connecting block 8 The bottom of the block 8 is fixedly plugged with a cutting knife 9, both sides of the lifting cylinder 7 are fixed with a collar 10, and both sides of the lifting cylinder 7 are rotatably connected with a rotating shaft 11, and one end of the two rotating shafts 11 is fixedly sleeved with a rotating block 12, one side of the side plate 2 is fixed with two symmetrical partitions 16, and the two partitions 16 are provided with a sliding opening 17, and a sliding baffle 14 is slidably provided between the two sliding openings 17, and three plugs 13 are fixed on both sides of the sliding baffle 14, and the outer surfaces of the two plugs 13 in the middle of the sliding baffle 14 are rotatably sleeved on one end of the two rotating blocks 12, and one of the six plugs 13 The ends are fixedly connected to the limit plates 15. By turning on the motor 3 and rotating the screw 5, the threaded connecting plate 4 drives the lifting cylinder 7 to move up and down, and the lifting of the lifting cylinder 7 drives the cutting knife 9 to move up and down to cut the stacked papers placed between the two partitions 16 inside the chassis 1. In the process of cutting the stacked papers, the pressing block 21 will contact the non-cutting surface of the paper in advance and shrink toward the inside of the lifting cylinder 7 under the elasticity of the two springs 19. Therefore, when the pressing block 21 is in contact with the stacked papers, the stability of the stacked papers is ensured. After the lifting cylinder 7 gradually descends, the cutting knife 9 starts to cut the stacked papers. The cutting is carried out until the stacked paper is cut, thereby ensuring the stability of the stacked paper cutting. During the entire cutting process, the descent of the lifting cylinder 7 will use the two rotating shafts 11 to push the two rotating blocks 12 to rotate, and use the two plug posts 13 to push the sliding baffle 14 to slide inside the two sliding openings 17, so that when the cutting knife 9 descends, the sliding baffle 14 is pushed away from the bottom of the cutting knife 9. When not cutting, the sliding baffle 14 can protect the position below the cutting knife 9 to avoid the safety hazards that may occur such as the cutting knife 9 falling off, and the sliding baffle 14 slides synchronously with the cutting work without affecting the progress of the cutting work.
[0020] In order to ensure the stable sliding of the sliding baffle 14 on the two partitions 16, three pins 13 are grouped into two groups, and the two groups of pins 13 are respectively slidably arranged inside the two sliding openings 17, and one side of the six limiting plates 15 is respectively fitted with one side of the two partitions 16.
[0021] In order to utilize the rotation of the screw 5 to enable the slide 6 to drive the lifting cylinder 7 to move up and down, one end of the threaded connecting plate 4 is slidably inserted into the interior of the slide 6, and both sides of the threaded connecting plate 4 are respectively fitted with both sides of the slide 6.
[0022] Furthermore, in order to allow the top end of the insert block 20 to slide stably inside the lifting cylinder 7 , the top end of the insert block 20 is slidably inserted into the interior of the lifting cylinder 7 , and the outer surface of the insert block 20 fits against the inner wall of the lifting cylinder 7 .
[0023] Furthermore, in order to use the pressure block 21 to press the stacked paper in advance and ensure stability during cutting, the pressure block 21 is located below the bottom end of the cutting knife 9, and one end of the pressure block 21 on one side of the cutting knife 9 forms a gap with the bottom end of the cutting knife 9, and one end of the sliding baffle 14 is located directly below the bottom end of the cutting knife 9.
[0024] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.
[0025] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. In addition, the various different embodiments of the present invention can also be arbitrarily combined, as long as they do not violate the concept of the present invention, they should also be regarded as the content disclosed by the present invention.
