Abstract
Description
Technical Field
[0001] This utility model relates to the field of lottery processing technology, specifically to a lottery paper cutting device. Background Technology
[0002] Lottery tickets typically require paper to be cut during processing to meet the processing requirements. Existing paper cutting devices mainly use cutters to cut the paper.
[0003] A relevant reference is Chinese utility model patent CN220661065U, which discloses a paper cutting device, including a conveying mechanism, a positioning mechanism, and a cutting mechanism. The conveying mechanism includes a first conveyor belt for conveying paper. The positioning mechanism includes two positioning units, respectively disposed on both sides of the first conveyor belt. Each positioning unit includes a connecting plate, a positioning plate, and a first driving member. The positioning plate is rotatably mounted on the connecting plate and has an elongated hole. The movable end of the first driving member passes through the elongated hole to drive the positioning plate to rotate in a horizontal plane. The cutting mechanism includes a second driving member and a cutter. The second driving member drives the cutter to move vertically so that the cutter can contact the paper. By coordinating the conveying mechanism, positioning mechanism, and cutting mechanism, the positioning accuracy and cutting accuracy of the paper can be improved, paper miscutting can be avoided, and paper quality can be improved.
[0004] In order to reserve the position of the blade, the existing paper cutting device has an opening structure on the surface of the support structure that fits into the blade. This method will result in the bottom of the paper having no support structure during cutting, and the paper will bend during cutting, affecting the cutting effect. At the same time, the existing cutter moves vertically downward, and there is no relative displacement between the blade edge and the paper. The cutter cannot effectively cut the paper by sliding, which may cause paper jams. Utility Model Content

[0009] As a preferred embodiment of this utility model, the base plate has a groove structure at its center that fits into the adhesive strip, the adhesive strip has a groove structure at its center, and the adhesive strip is located directly below the cutter; the base plate can support the fixing frame.
[0010] As a preferred embodiment of this utility model, the positioning plate is symmetrically installed on the left side of the base plate with the center of the cutter as the reference, and the fixing rod is symmetrically installed on the front and rear sides of the left end of the limiting frame. The top of the fixing frame is fixedly connected to the limiting frame. The fixing frame can support the right side of the limiting frame.
[0011] As a preferred technical solution of this utility model, the limiting frame is installed on the top of the base plate in an inclined state through the fixing rod and the fixing frame. The axial direction of the pressing piston is perpendicular to the top surface of the limiting frame. The pressing piston is symmetrically installed inside the limiting frame, and the movable end of the pressing piston is inclined towards the base plate. The limiting frame can restrict the position of the pressing piston.
[0012] As a preferred embodiment of this utility model, the connecting frame is movably connected to the limiting frame via a pressing piston, and the sliding groove is symmetrically arranged on the front and rear sides of the connecting frame with the center of the connecting frame as a reference; the connecting frame can limit the position of the cutter.

[0014] As a preferred embodiment of this utility model, the connecting rod, the slider, and the limiting tube form a sliding connection; the pressure plate is movably installed below the slider via connecting rods of different lengths on the left and right sides; the spring is located between the bottom end of the limiting tube and the pressure plate; the pressure plate can limit the position of the paper.
[0015] Compared with the prior art, the present invention provides a lottery paper cutting device, which has the following advantages:
[0016] 1. This utility model uses a limiting frame, which is installed at an angle above the base plate via a fixing rod and a fixing bracket. The axis of the pressing piston is perpendicular to the top surface of the limiting frame. The pressing pistons are symmetrically installed inside the limiting frame, and the movable end of the pressing piston is inclined towards the base plate. The cutter is fixedly connected to the movable end of the pressing piston via a connecting bracket. The blade of the cutter is horizontal. When the pressing piston extends, the connecting bracket at the bottom will drive the cutter to move to the lower right to cut the paper.

A spring is located between the bottom of the limiting tube and the pressure plate. The slider can adjust the relative position between the connecting rod and the connecting frame by sliding. When the bottom pressure plate cannot move downwards, it slides to the left end of the groove in an inclined state, causing the limiting tube to compress the spring. The reaction force exerted by the spring on the pressure plate during compression allows the pressure plate to press the paper above the bottom plate, thus limiting the front and rear positions of the paper at the cutting point and preventing deformation during cutting. Simultaneously, the adhesive strip provides support to the paper at the front and rear sides of the cutting point, further preventing deformation and ensuring proper cutting.

[0026] Please see Figure 1 - Figure 4 In this embodiment, a lottery paper cutting device includes: a base plate 1, an adhesive strip 11 fixedly installed on the top of the base plate 1, a positioning plate 12 fixedly installed on the top of the base plate 1, a fixing rod 13 fixedly installed on the left side of the base plate 1, a fixing frame 14 fixedly installed on the right side of the base plate 1, a limiting frame 15 fixedly installed on the top of the fixing frame 14, a pressing piston 16 inserted inside the limiting frame 15, a connecting frame 17 fixedly installed at the bottom end of the pressing piston 16, a sliding groove 18 provided on the surface of the connecting frame 17, a cutter 19 fixedly installed below the connecting frame 17, a slider 110 movably installed inside the sliding groove 18, a limiting tube 111 fixedly installed below the slider 110, a connecting rod 112 inserted inside the limiting tube 111, a spring 113 inserted outside the connecting rod 112, and a pressure plate 114 fixedly installed at the bottom end of the connecting rod 112.
[0027] The base plate 1 has a groove structure at its center that fits into the adhesive strip 11. The adhesive strip 11 is located directly below the cutter 19. The positioning plate 12 is symmetrically installed on the left side of the base plate 1 with the center of the cutter 19 as the reference. The fixing rod 13 is symmetrically installed on the front and rear sides of the left end of the limiting frame 15. The top of the fixing frame 14 is fixedly connected to the limiting frame 15. The limiting frame 15 is installed on the top of the base plate 1 at an angle through the fixing rod 13 and the fixing frame 14. The axis of the pressing piston 16 is perpendicular to the top surface of the limiting frame 15. The pressing piston 16 is symmetrically installed inside the limiting frame 15, and the movable end of the pressing piston 16 is inclined towards... The base plate 1 and the connecting frame 17 are movably connected to the limiting frame 15 via the pressing piston 16. The sliding groove 18 is symmetrically arranged on the front and rear sides of the connecting frame 17 with the center of the connecting frame 17 as the reference. The slider 110 is slidably connected to the connecting frame 17 via the sliding groove 18. The top end of the connecting rod 112 is provided with an annular protrusion structure. The bottom outer side of the limiting tube 111 is provided with an annular protrusion structure. The connecting rod 112 is slidably connected to the slider 110 and the limiting tube 111. The pressure plate 114 is movably installed below the slider 110 via the connecting rods 112 of different lengths on the left and right sides. The spring 113 is located between the bottom end of the limiting tube 111 and the pressure plate 114.
[0028] Specifically, the base plate 1 restricts the position of the adhesive strip 11, which is located directly below the cutter 19. The adhesive strip 11 provides support from the bottom of the paper on both sides of the paper cutting position and protects the blade of the cutter 19. The positioning plate 12 and the cutter 19 are perpendicular to each other, ensuring that the cutter 19 remains perpendicular to the left side of the paper during cutting. The fixing rod 13 and the fixing bracket 14 have different heights, allowing the limiting bracket 15 to be installed at an angle above the base plate 1. The limiting bracket 15 restricts the position of the pressing piston 16. When the pressing piston 16 extends, the connecting bracket 17 at its bottom will drive the cutter 19 towards... The paper is cut by moving to the lower right. The connecting frame 17 can restrict the position of the slider 110. The slide groove 18 can facilitate the sliding of the slider 110. The slider 110 can adjust the relative position between the connecting rod 112 and the connecting frame 17 by sliding. When the bottom pressure plate 114 cannot move downward, it can slide to the left end of the slide groove 18 in an inclined state and downward, driving the limiting tube 111 to squeeze the spring 113. The reaction force exerted by the spring 113 on the pressure plate 114 when compressed makes the pressure plate 114 press the paper on the bottom plate 1, thereby restricting the front and rear sides of the paper cutting point and preventing the paper from deforming during cutting.
[0029] In use, the limiting frame 15 is installed at an angle above the base plate 1 via the fixing rod 13 and the fixing frame 14. The axis of the pressing piston 16 is perpendicular to the top surface of the limiting frame 15. The pressing piston 16 is symmetrically installed inside the limiting frame 15, and the movable end of the pressing piston 16 is inclined towards the base plate 1. The cutter 19 is fixedly connected to the movable end of the pressing piston 16 via the connecting frame 17. The blade of the cutter 19 is horizontal. When the pressing piston 16 extends, the connecting frame 17 at the bottom will drive the cutter 19 to move to the lower right to cut the paper. This method allows the cutter 19 to move to the right while pressing down during the paper cutting process, creating a relative displacement with the paper, which improves the cutting effect and avoids paper jams. The slider 110 is slidably connected to the connecting frame 17 via the sliding groove 18. The top of the connecting rod 112 is provided with an annular protrusion structure, and the bottom outer side of the limiting tube 111 is provided with... The ring-shaped protrusion structure forms a sliding connection between the connecting rod 112, the slider 110, and the limiting tube 111. The pressure plate 114 is movably installed below the slider 110 via the connecting rods 112 of different lengths on the left and right sides. The spring 113 is located between the bottom end of the limiting tube 111 and the pressure plate 114. The slider 110 can adjust the relative position between the connecting rod 112 and the connecting frame 17 by sliding, so that when the bottom pressure plate 114 cannot move downward, it can slide to the left end of the slide groove 18 in an inclined state and downward, causing the limiting tube 111 to squeeze the spring 113. Through the reaction force exerted by the spring 113 on the pressure plate 114 when compressed, the pressure plate 114 can press the paper above the bottom plate 1, thereby limiting the front and rear sides of the paper cutting point and preventing the paper from deforming during cutting. At the same time, the adhesive strip 11 can support the paper on the front and rear sides of the paper cutting point, thereby avoiding deformation of the paper during cutting and affecting the cutting.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
