DETAILED DESCRIPTION
[0023] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.
[0024] like Figure 2-3 As shown, an embodiment of the utility model provides a stapling drive device, which is used on binding office equipment, including a frame 1, a driving mechanism 2 arranged on the frame, a stapling mechanism 3 connected to the driving mechanism and arranged on the frame, and a hooking mechanism 4 arranged on the frame 1 and connected to the driving mechanism and driven by the driving mechanism.
[0025] Specifically, Figure 2 As shown, the rack 1 includes two parallel mounting plates 101; at the same time, each mounting plate is square, and a rectangular baffle 102 perpendicular to the mounting plate is provided at each of its four side edges, and the four baffles and the mounting plate enclose an installation space.
[0026] like Figure 2-4As shown, in this embodiment, the driving mechanism 2 includes a driving assembly 210, wherein the driving assembly includes a motor 210a disposed on the inner surface of one of the mounting plates 101, a driven gear 210b located outside the mounting plate and connected to the motor output end through a synchronous belt; a rotating shaft 201 connected to the driving assembly and mounted on the mounting plate 101, wherein the driven gear is sleeved on one end of the rotating shaft 201, a crank 202 disposed on the rotating shaft and located outside the mounting plate and linked thereto, that is, when the rotating shaft rotates, the crank is driven to rotate therewith; a rivet guide plate 203 connected to the crank and performing reciprocating linear motion relative to the frame when the crank rotates, and a connecting rod 204 connected to the rivet guide plate at one end. The rotating shaft 201 is mounted on the mounting plate 101 through a bearing 6.
[0027] Furthermore, a transverse guide hole 203a is provided in the rivet guide plate 203, a cylinder 205 is provided on the outer surface of the crank 202 with one end vertically connected thereto, a convex ring 206 is provided on the outer wall of the cylinder and is integrally formed therewith, the convex ring is movably arranged in the transverse guide hole and in contact therewith; the transverse guide hole includes an arc segment 203b. Figure 1 As shown, when the rotating shaft 201 rotates, it drives the crank 202 to rotate, and its rotation radius is R2. The radius of the arc segment 203b here is R1, and R1=R2; during the rotation process, the convex ring 206 moves in the transverse guide hole 203a (including the arc segment 203b) and pushes the rivet guide plate 203 to move, thereby pushing the connecting rod 204 to move.
[0028] like Figure 3-4 As shown, the driving mechanism 2 further includes a guide rail mounting plate 207 disposed on the outer surface of the mounting plate 101, a guide rail 208 disposed thereon, and a slider 209 movably disposed on the guide rail; the rivet guide plate 203 is fixedly connected to the slider. With this structure, when the rivet guide plate moves, the slider 209 is driven to move on the slide rail 208, ensuring that the connecting rod 204 moves more smoothly.
[0029] In this embodiment, in order to make the driving mechanism more stable, the crank 202, rivet guide plate 203, connecting rod 204, cylinder 205, convex ring 206, guide rail mounting plate 207, guide rail 208 and slider 209 are all arranged in pairs, that is, two of each of the above components are arranged; the two cranks are respectively arranged at the two ends of the rotating shaft 201 and are located on the outside of the two mounting plates 101.
[0030] like Figure 2-3As shown, the nailing mechanism 3 includes a nail rod 301 vertically connected to the other end of the connecting rod 204 and arranged horizontally, a stapler mounting plate 302 whose two ends are respectively fixedly connected to the inner surfaces of the two mounting plates 101, a stapler 303 whose one end is fixedly connected to the stapler mounting plate, and two guide plates 304 respectively installed outside the two mounting plates, each of which is provided with a strip guide hole 304a, and the two guide plates are parallel to each other and sleeved on the outside of the nail rod 301; the nail rod can move in the guide hole; and a protrusion 303a is provided on the back of the stapler 303, which is clamped in the nail rod 301. Here, the protrusion 303a is used to drive the nailing on the stapler 303, and the upper and lower stapler actions are: downward movement "pulling iron wire - cutting iron wire - bending iron wire - pushing iron wire to penetrate paper" - upward movement to return to the initial state, clamped in the horizontal groove of the nail rod 301, and moving up and down with the nail rod 301.
[0031] like Figure 2-3 As shown, the nail hooking mechanism 4 includes a hooking box connecting plate 401 whose two ends are respectively connected to the two mounting plates 101, a hooking box 402 arranged thereon, a nail pushing rod 403 whose two ends are respectively movably connected to the two mounting plates 101, a movable hooking nail pushing rod 405 whose two ends are respectively connected to the hooking box and the nail pushing rod, and a nail pushing guide wheel assembly 404 arranged at the end of the nail pushing rod; the crank 202 is connected to the nail pushing guide wheel assembly. The nail hooking push rod 405 can move up and down on the hooking box 402 to hook nails. The nail pushed by the stapler 303 is shaped like A, penetrates the paper, moves down to the lowest point, and the nail hooking push rod immediately moves up. Before the stapler 303 moves up, the nail hooking push rod reaches the top to complete the nail hooking action. The hooked nail is shaped like B. Figure 6 shown.
[0032] Specifically, Figure 3 As shown, the nail pushing guide wheel assembly 404 is divided into two groups, which are respectively arranged at the two ends of the nail pushing rod 403; it includes a nail pushing block 404a connected to the end of the nail pushing rod 403, and a guide wheel 404b arranged on the outer surface of the nail pushing block; the guide wheel is tangent to the crank 202.
[0033] Two mutually parallel guide rods 5 are respectively arranged on the outer surfaces of the two mounting plates 101, with a gap therebetween; both ends of the nail pushing rod 403 respectively vertically penetrate the two mounting plates and are inserted into the gap.
[0034] With the above structure, the driving assembly 210 drives the rotating shaft 201 to rotate, and at the same time drives the crank 202 to rotate, thereby driving the rivet guide plate 203, the connecting rod 204 and the rivet rod 301 to move up and down to complete the nailing action, and the outer contour of the crank 202 drives the rivet guide wheel assembly 404 to push up at the appropriate time, and drives the rivet rod 403 to move up and down to complete the nail hooking action.
[0035] like Figure 5 As shown, in Figure 1 In the figure, the movement law of the connecting rod 204 when R1=R2=25mm and α=40°, the angle in the coordinate axis is the angle between the crank 202 and the horizontal line; α is the angle of the arc segment 203b in the rivet guide plate 203; when the connecting rod 204 stops during the operation of this mechanism, the convex ring 206 moves to the arc groove of α°, and this angle controls the static time of the connecting rod 204. The displacement is the position change of a certain point on the connecting rod 204.
[0036] The nail driving device of the utility model adopts a double slider mechanism to achieve the characteristics of a cam mechanism. The so-called double slider mechanism here mainly refers to other components of the driving mechanism 2, the nailing mechanism 3 and the hooking mechanism 4 except the stapler 303 and the tight hook box 402.
[0037] In the above description, it should be noted that the terms "installed", "connected", "connected" and other corresponding terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two components; "provided in" should be understood as "installed in, set in", including fixed installation, movable installation and other installation methods.
