Abstract
Description
Technical Field
[0001] The present application belongs to the field of pressure riveting and binding technology, and in particular relates to an upper rivet head moving mechanism. Background Art
[0002] During punching and riveting, the upper heating box moves in the paper pressing arm, and the lower bottom surface of the existing upper rivet head is usually designed to be at the same height as or higher than the bottom of the paper pressing arm.
[0003] During riveting, the paper press arm must first press down on the binding material, which is paper. When pressure is applied, air enters the gaps between adjacent sheets of paper, causing a bulge in the paper where it is pressed, causing the bulge to rise above the bottom of the paper press arm. If the lower surface of the upper rivet head is set at the same height as the bottom of the paper press arm, the bottom of the rivet head will interfere with the bulge and will not be able to move forward along the inside of the paper press arm to the riveting position.
[0004] Furthermore, when the paper pressing arm presses against the binding, the heating box must move forward normally. The bottom of the upper rivet head must be above the bottom of the paper pressing arm. However, this excessively high position of the lower rivet head prevents it from fully contacting the binding during riveting, resulting in inconsistent upper and lower flaps after riveting. When the lower rivet head fully contacts the binding, there will be a certain distance between the upper rivet head and the binding. This causes the upper rivet flap to protrude above the upper end surface of the binding, while the lower rivet flap will contact the binding. This results in inconsistent riveting effects between the upper end surface and the lower bottom surface. The upper rivet flap protrudes above the binding, and the protruding flap on the upper end surface can puncture the cover when binding. Summary of the Invention

[0011] Furthermore, the adjustment frame is constructed as a bracket with a U-shaped cross section, and the upper rivet head spans the width of the bracket through a connecting rod and is movably connected to the adjustment hole.

[0032] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] This embodiment proposes a mechanism for moving the upper rivet head, such as Figure 1 As shown, the apparatus includes an adjustment frame 40 for mounting an upper rivet head 50, a limiting post 80 fixed to the top of the paper pressing arm 20 via a limiting plate 90, a fixed frame 60 fixed to the mounting plate, and a sliding frame 70 for driving the upper rivet head 50 to move horizontally. The paper pressing arm 20 is fixed to the mounting plate 10 via two vertical guide posts. The fixed frame 60 is disposed at the rear end of the paper pressing arm 20 and fixed to the mounting plate 10, i.e., the fixed frame 60 is fixed to the side of the mounting plate 10 away from the limiting post 80. The sliding frame 70 is disposed at the upper portion of the fixed frame 60 and can drive the upper rivet head 50 to move left and right along the lateral width of the fixed frame 60 via the adjustment frame 40. The adjustment frame 40 is driven to drive the upper rivet head 50 forward, thereby driving the upper rivet head 50, which is located at the highest position of the adjustment hole 41, to move to the riveting position. When the limiting post 80 abuts against the upper rivet head 50 and causes the upper rivet head 50 to move to the lowest position in the adjustment hole 41, riveting is ready to begin.
[0034] like Figure 2As shown, the adjustment bracket 40 is constructed as a bracket with a U-shaped cross-section and is provided with adjustment holes 41 for adjusting the height of the upper rivet head 30. There are at least two sets of adjustment holes 41, which are constructed on both sides of the adjustment bracket 40 and are located at one end of the adjustment bracket 40 near the limiting post 80.
[0035] The upper rivet head 30 is positioned across the width of the adjustment frame 40 via a connecting rod and is movably connected to the adjustment hole 41 via the connecting rod. A heater 51 for heating the upper rivet head 50 and a heat shield 52 for heat insulation are also mounted on the adjustment frame 40. The upper rivet head 50 and heater 51 are integrally connected and arranged on the inner side of the adjustment frame 40, while the heat shield 52 is fixed to the outer side of the adjustment frame 40. The upper rivet head 50 and heat shield 52 are positioned together at the same end of the adjustment frame 40, near the top end of the paper pressing arm 20. The adjustment frame 40 drives the upper rivet head 50, heater 51, and heat shield 52 together, which are built into the interior of the paper pressing arm 20 and are pushed forward or backward in the horizontal direction by the sliding frame 70.
[0036] A torsion spring 42 is provided adjacent to a set of adjustment holes 41 located inside the adjustment frame 40. The torsion spring 42 is movably connected to the adjustment frame 40 via a rotating shaft. The torsion spring 42 is fixed to the outer wall of the rotating shaft, and a connecting rod is arranged parallel to the rotating shaft in the width direction of the adjustment frame 40. One end of the torsion spring 42 abuts against the side of the heating element 51 integrally connected to the upper rivet head 30, while the other end abuts against the top surface of the inner wall of the adjustment frame 40.
[0037] Sliding frame 70 is provided with an elongated circular hole and is connected to fixed frame 60 via two sets of rollers, driving sliding frame 70 to move horizontally relative to the width of fixed frame 60. A connecting frame 43 is provided at one end of sliding frame 70, and sliding frame 42 is connected to the tail of adjustment frame 40 via the vertical connecting frame 43. Therefore, sliding frame 70 can drive adjustment frame 40 to move horizontally.
[0038] Furthermore, the connecting frame 43 is constructed as a C-shaped fixed frame, and a cylinder is provided at its end. The tail wing of the adjustment frame 40 is fixed between the connecting frame 43 and the cylinder through a connecting piece, and the adjustment frame 40 can move up and down along the height direction of the connecting frame 43 through the connecting piece.
[0039] The limiting post 80 is arranged at the front end of the adjustment frame 40 and is fixed to the paper pressing arm 20 through the limiting plate 90 and close to the upper rivet head 50. The limiting post 80 is arranged perpendicular to the limiting plate 90 and is suspended toward the upper rivet head.
[0040] like Figure 3As shown, the adjustment hole 41 is constructed as an obtuse-angled V-shaped structure, one side of which is arranged horizontally, and the other side is arranged obliquely upward near the side of the limiting column 80, thereby forming an obtuse-angled L-shaped sliding process, which is convenient for adjusting the height position of the upper rivet head 50 so that it is located at different positions and heights, so as to solve the technical problem of its position being higher than the bottom surface of the paper pressing arm 20 during the forward movement, and the technical problem of its position being lower than the bottom surface of the paper pressing arm 20 during riveting.
[0041] like Figure 4 As shown, the upper rivet head 50 is set at its initial position, that is, at the highest position on the left end of the adjustment hole 41, and the front end of the sliding frame 70 is located at the front end of the fixed frame 60. At this time, the lower bottom surface of the upper rivet head 50 is higher than the bottom surface of the paper pressing arm 20, that is, the bottom surface of the upper rivet head 50 is located above the bottom surface of the paper pressing arm 20. At this time, when the adjustment frame 40 drives the upper rivet head 30 to be pushed by the sliding frame 70 to a position close to the limit plate 90, the upper rivet head 50 is located above the bottom surface of the paper pressing arm throughout the entire process. The paper pressing arm presses the binding material, causing the paper to bulge in the middle of the pressed position. In this way, even if the upper rivet head 50 is pushed forward, the bottom surface of the upper rivet head 50 will avoid the bulging paper, thereby ensuring that the lower bottom surface of the upper rivet head can move forward normally to the pressing position.
[0042] like Figure 5 As shown, when the upper rivet head 30 is at the riveting position, the adjustment frame 40 is driven by the sliding frame 70, and the side wall of the heating element 51 contacts the limiting post 90 first. When the adjustment frame 40 moves forward to its limit position, the limiting plate 90 remains stationary on the paper pressing arm 20; the limiting post 90 abuts the end of the heating element 51, and then abuts the heating element 51 to drive the upper rivet head 30 to move backward along the channel of the adjustment hole 41, and retreat from the highest position of the adjustment hole 41 to the lowest position; at the same time, the adjustment frame 40 also moves downward along the height of the connecting frame 43. At this time, the bottom surface of the upper rivet head 30 is located below the bottom surface of the paper pressing arm 20, and the lower bottom surface of the upper rivet head 30 is 1 mm lower than the bottom of the paper pressing arm 20, and the riveting action can begin, so that the upper riveting cap can be ensured to fit the pressed object during riveting.
[0043] When the upper rivet head 30 is at the lowest position in the adjustment hole 41, the torsion spring 42 is pushed by the heater 51 to contract and tighten. After the riveting is complete, the sliding frame 70 drives the adjustment frame 40 and the upper rivet head 50 backward, that is, away from the stop post 80. After the heater 51 moves away from the stop post 80, it is pushed by the rebound force of the torsion spring 42, driving the upper rivet head 50 upward from the lowest position in the adjustment hole 41 to its highest position, returning to its initial position. At the same time, the adjustment frame 40 drives the upper rivet head 50 upward along the height direction of the connecting frame 43 to the top position of the connecting frame 43.
[0044] A binding machine is provided with the moving mechanism described above.
[0045] The upper rivet head movement mechanism designed in this application has a simple structure and reasonable coordination. It can adjust the position and height of the upper rivet head based on different positions to adapt to the height requirements in different states. This allows the bottom of the upper rivet head to avoid the raised position of the pressed object during forward or backward movement. It also ensures that the upper rivet cap fits the pressed object, achieving high-quality and efficient riveting. This application also proposes a binding machine equipped with this movement mechanism.

The contents described are only preferred embodiments of the present application and should not be considered to limit the scope of implementation of the present application. All equivalent changes and improvements made within the scope of the present application should still fall within the scope of the patent application.
