Description

Technical Field

[0001] This utility model relates to the field of binding machine technology, specifically a paper conveying device for a binding machine. Background Technology

[0002] A binding machine is a binding device that uses mechanical means to fix paper, plastic, leather, etc. with binding staples, hot melt adhesive, nylon tubing, etc. According to different uses, it can be divided into industrial binding machines and civilian binding machines. They are commonly used in printing plants, financial offices of enterprises and institutions, archives management and other places.

[0003] In the operation of a binding machine, the paper feeding device is one of the key components, and its performance directly affects the binding quality and efficiency. Currently, paper feeding in binding machines is generally done manually by placing stacked papers directly into the machine, punching holes, and then performing the binding operation. This method has poor safety performance. Some existing feeding devices also use automatic feeding methods, but without an effective correction and positioning mechanism, the paper is prone to skewing and disorder after punching, thus affecting subsequent binding operations. Therefore, there is an urgent need to design a paper feeding device for binding machines to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a paper feeding device for a binding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 In this embodiment of the present invention, a paper conveying device for a binding machine includes:

[0030] The binding machine body 1 has mounting ears 2 on both sides, and one end of the mounting ears 2 is fixed to the same frame 3;

[0031] The support platform 4 is slidably disposed on the inner wall of the frame 3, and a conveying mechanism 7 for driving the support platform 4 is fixedly installed on the frame 3. The conveying mechanism 7 includes a threaded rod 71 rotatably disposed on the inner wall of the frame 3, and a forward and reverse motor 74 for driving the threaded rod 71 to rotate is fixedly installed on the outer wall of one end of the frame 3. A movable seat 73 is screwed onto the threaded rod 71, and the movable seat 73 is fixedly installed on the bottom side of the support platform 4. Guide grooves are provided on both sides of the movable seat 73, and a guide rod 72 passing through the guide groove is fixed on the inner wall of the frame 3. A binding opening 11 is provided on the top side of the support platform 4, and the position of the binding opening 11 corresponds to the binding area of ​​the binding machine body 1. The forward and reverse motor 74 drives the threaded rod 71 to rotate, which drives the movable seat 73 to move, thereby driving the support platform 4 to slide within the frame 3, which facilitates the conveying of paper.

[0032] A positioning plate 6 is fixed to one end of the top of the support platform 4, and a correction mechanism 8 is provided on the positioning plate 6. The correction mechanism 8 includes movable grooves 83 on both sides of the bottom of the positioning plate 6, and each movable groove 83 has an insertion hole 810 through the positioning plate 6 at one end. A pull rod 86 is inserted into the inner wall of each insertion hole 810. A pull ring 82 is fixed to one end of the pull rod 86, and a correction plate 81 inserted into the movable groove 83 is fixedly installed at the other end of the pull rod 86. A spring 85 is fixedly installed on one side of the correction plate 81 and the inner wall of one end of the movable groove 83, and a spring 85 is provided on the other side of the correction plate 81. There is a protective pad 84, and a through groove 87 is opened between the other ends of the two movable grooves 83. A gear 88 is rotatably connected in the middle of the inner wall of the through groove 87. A rack 89 is fixedly installed on one side of each of the two straightening plates 81. The two racks 89 are respectively inserted into the top and bottom of the inner wall of the through groove 87. Both racks 89 mesh with the gear 88. Pulling the pull ring 82 drives the pull rod 86 to move. The racks 89 on the straightening plates 81 connected to the pull rod 86 mesh with the gear 88 in the through groove 87, so that the straightening plates 81 on both sides move synchronously, thereby straightening the edge of the paper and ensuring that the paper is neat.

[0033] The positioning mechanism 5 is located on one side of the positioning plate 6 and above the support platform 4. The positioning mechanism 5 includes a U-shaped frame 51 hinged to one side of the positioning plate 6. One end of the U-shaped frame 51 and the top of the support platform 4 are provided with positioning screw holes 56. A positioning screw 52 is screwed into the inner wall of the positioning screw hole 56. A knob 53 is fixed to the top of the positioning screw 52. Movable plates 55, which are equidistant and inclined, are hinged to both sides of the bottom of the U-shaped frame 51. Memory metal springs 57 are installed at the top of the movable plates 55 and the bottom of the U-shaped frame 51. A positioning roller 54 is provided at the bottom of the movable plates 55. A protective sleeve is provided on the outer wall of the positioning roller 54. By rotating the knob 53, the positioning screw 52 is screwed into the positioning screw hole 56, and the height of the U-shaped frame 51 is adjusted so that the positioning roller 54 presses the paper under the action of the memory metal spring 57, thereby positioning the paper.

[0034] Specifically, the support platform 4 has sliding grooves 9 on both sides, and the inner walls of both sides of the platform frame 3 are fixedly installed with slide rails 10 inserted into the sliding grooves 9. Through the cooperation of the sliding grooves 9 and the slide rails 10, the support platform 4 moves smoothly and realizes automatic paper feeding.

[0035] The working principle of this utility model is as follows: When in use, the user places the paper on the support platform 4, pulls the pull ring 82 to drive the pull rod 86 to move, and the rack 89 on the straightening plate 81 connected to the pull rod 86 meshes with the gear 88 in the through groove 87, so that the straightening plates 81 on both sides move synchronously to straighten the edge of the paper and ensure that the paper is neat.

[0036] Next, close the U-shaped frame 51, and drive the positioning screw 52 into the positioning screw hole 56 by rotating the knob 53. The height of the U-shaped frame 51 can be adjusted. The positioning roller 54 on the bottom movable plate 55 of the U-shaped frame 51 presses the paper under the action of the memory metal spring sheet 57, thereby positioning the paper.

[0037] Finally, the forward and reverse motor 74 drives the threaded rod 71 to rotate. The movable seat 73, which is screwed to the threaded rod 71, can only move axially due to the restriction of the guide rod 72. The movable seat 73 is fixed to the bottom of the support platform 4, thereby driving the support platform 4 to slide within the frame 3. At the same time, the sliding grooves 9 on both sides of the support platform 4 cooperate with the sliding rails 10 on the inner wall of the frame 3 to ensure that the support platform 4 moves smoothly and realizes automatic paper feeding. This makes the binding opening 11 on the top of the support platform 4 correspond to the binding area of ​​the binding machine body 1. When the support platform 4 feeds the positioned and corrected paper to the designated position, the binding machine body 1 can accurately punch and bind the paper.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
