[0002] A three-sided book trimmer is a machine that trims the rough edges on three sides of a book one by one at a time. The main types include semi-automatic, automatic, and double-cutting. Currently, the cutting position of some three-sided book trimmers is relatively close to the book inlet. Operators are at risk of being scratched by the cutting knife when placing books. In order to maintain its stability during the cutting process, the book trimmer usually presses on the book from the top.
[0003] During the use of the three-sided book trimmer, due to its working characteristics, additional protection mechanisms are required for the equipment itself and the operator: in terms of equipment protection, since the cutter head is prone to hard contact with the work platform when cutting to the bottom, the cutter head may wear too quickly, increasing the equipment maintenance cost; in addition, during the operation of the equipment, it is strictly forbidden for personnel's limbs or other objects to enter the operating area, otherwise it may cause personal safety problems or equipment damage. Therefore, a protection mechanism for a fully automatic three-sided book trimmer is proposed.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 4 The utility model provides a technical solution: a protective mechanism for a fully automatic three-sided book trimmer, comprising a water flow table 1, protective covers 3 are installed on both sides of the water flow table 1 through positioning hinges 2, a locking buckle 4 is installed on one side of the top of one group of protective covers 3, and an operating component 5 is welded and installed on one end of the surface of the water flow table 1.
[0022] The operating component 5 includes a track frame 501, the top of the inner wall of the track frame 501 is connected to a pressure plate 502 through a cylinder, side cutters 504 are respectively attached to both sides of the inner wall of the track frame 501, one end of the side cutter 504 is attached to a cross-cutting knife 503, and stabilizing sliders 505 are respectively installed at both ends of the cross-cutting knife 503 and one side of the surface of the side cutter 504.
[0023] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a push rail 101 is provided on the surface of the water flow table 1, and a push slider 102 is attached to the inner wall of the push rail 101. One end of the push slider 102 is connected to a push rod 103 through a hinge. One end of the surface of the water flow table 1 is connected to a protection pad 105 through a buffer spring 104. The top of the protection pad 105 is parallel to the surface of the water flow table 1. The push rod 103 forms a sliding structure between the push slider 102 and the push rail 101. In this structure, the protection pad 105 is parallel to the surface of the water flow table 1, which will not affect the entry of paper into the cutting area, and the movement of the push rod 103 in the push rail 101 can smoothly deliver the paper to be cut to the cutting area.
[0024] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the protective cover 3 forms a rotating structure with the water flow table 1 through the positioning hinge 2, and the height of the protective cover 3 is greater than the height of the track frame 501. This structure can provide an outer protective structure for the operating component 5 during operation, so that no foreign objects can enter the cutting area, ensuring the normal operation of the machine and the personal safety of the operator.
[0025] In this embodiment, Figure 2 , Figure 4 As shown, the inner wall of the track frame 501 is provided with a track, and the cross-cutting knife 503 and the side cutting knife 504 are respectively fitted with the track of the inner wall of the track frame 501 through the stabilizing slider 505. This structure enables the cross-cutting knife 503 and the side cutting knife 504 to maintain a stable and vertical running track during cutting operation, thereby reducing damage to the knife head caused by the unstable running track.
[0026] In this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, the protection pad 105 is arranged directly below the cross-cutting knife 503 and the side cutting knife 504, and the protection pad 105 forms an elastic structure with the surface of the water table 1 through the buffer spring 104. This structure can make soft contact with the water table 1 through the protection pad 105 when the cross-cutting knife 503 and the side cutting knife 504 cut to the bottom of the paper, thereby protecting the knife head.
[0027] In this embodiment, Figure 2 and Figure 4 As shown, the pressing plate 502 is arranged in the rectangular range surrounded by the side cutting knife 504 and the cross cutting knife 503. The pressing plate 502, the cross cutting knife 503 and the side cutting knife 504 respectively form a reciprocating structure between the cylinder and the track frame 501. This structure can compress the paper to be cut, remove the air and gaps between the papers, and provide necessary preliminary preparations for cutting.
[0028] The use method and advantages of the utility model: The protection mechanism of the fully automatic three-sided book trimmer works as follows when in use:
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the protective covers 3 on both sides of the water flow table 1 are combined and docked through the positioning hinge 2, and then the two sets of protective covers 3 are locked and limited to each other through the locking buckle 4 on the top of one side of the protective cover 3; then the paper to be cut is transported to one end of the water flow table 1 through the conveying device, and the push rod 103 is closed to make the paper basically stable, and the paper to be cut is pushed into the cutting area by the sliding of the push slider 102 in the push slide rail 101; at this time, the pressure plate 502 on the top of the track frame 501 squeezes the paper under the action of the cylinder to remove the air and gaps between the papers, and then The cross cutter 503 and the two sets of side cutters 504 are turned on, so that the cross cutter 503 and the side cutters 504 respectively use the stabilizing slider 505 to perform cutting action along the track of the inner wall of the track frame 501, thereby ensuring the vertical movement of the cutter head during cutting and protecting the cutter head from damage caused by non-vertical forces. Furthermore, when the cutter head contacts the water flow table 1, the protective pad 105 contacted by the cutter head will generate pressure on the buffer spring 104, which will have a certain buffering effect on the contact action of the cutter head falling, thereby ensuring that the paper is completely cut off while reducing the wear of the cutter head due to hard contact and extending the service life of the cutter head.
[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
