A binding machine

Abstract

This utility model relates to a binding machine, including a tube cutting frame. The upper end of the tube cutting frame is equipped with a tube cutting mechanism. The tube cutting frame contains adjacent and interconnected tube drop channels and a horizontal tube space. The lower end of the tube cutting frame is equipped with a rivet box, which is slidably connected to the tube cutting frame. The rivet box can slide in and out of the tube cutting frame. The tube drop channels and the horizontal tube space are vertically opposite to and connected to the rivet box. In this utility model, the rivet box can slide in and out of the tube cutting frame, meaning that the rivet box can be opened or closed manually by pulling it out. This eliminates the need for a spring between the rivet box and the machine frame. Opening the rivet box prevents the rivets inside from suddenly flying out, and closing the rivet box prevents subsequently falling rivets from being ejected. Furthermore, cut rivets can fall and be stored in the rivet box, improving the rivet storage capacity.

Description

Technical Field

[0001] This utility model relates to a binding machine. Background Technology

[0002] Financial binding machines are used to bind financial vouchers, invoices, etc. They generally use nylon tube hot-press riveting binding. The riveting tube is used as a binding consumable. The entire process, from punching holes to inserting the riveting tube, is completed on paper products that have been stacked to a certain thickness. The entire operation process can be divided into steps such as punching holes, cutting tubes, inserting tubes, and pressing riveting.

[0003] In existing financial binding machines, severed rivets fall directly into the connector box. A spring connects the connector box to the frame. When the connector box opens, the spring force can cause an impulse, which can cause the rivets inside to suddenly fly out at the moment the box opens. Conversely, when the connector box closes, the spring return force can also cause an impulse, which, if it collides with a subsequently falling rivet, can propel it away. The connector box cannot store multiple rivets, and rivets that fall into it must be removed promptly to prevent rivet jamming. However, the process of opening the connector box to remove rivets can also result in subsequent severed rivets falling outside the box. Furthermore, rivets are lightweight and sometimes stick or get stuck on the inner wall of the passage leading to the connector box, making them difficult to remove. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a binding machine in which the rivet box adopts a pull-out structure. The rivet box can be opened and closed manually by pulling it out. When the rivet box is opened, the rivets inside the rivet box will not suddenly fly out. When the rivet box is closed, the fallen rivets will not be bounced away. It can also improve the rivet box's ability to store and collect rivets, so that the cut rivets can fall into the rivet box and will not get stuck on the inner wall of the channel or inside the rivet box.

[0005] The technical solution of this utility model is to provide a binding machine, including a tube cutting frame, a tube cutting mechanism at the upper end of the tube cutting frame, and a tube drop channel and a horizontal tube space that are adjacent to each other and connected inside the tube cutting frame; a tube rivet box at the lower end of the tube cutting frame, the tube rivet box being slidably connected to the tube cutting frame, the tube rivet box being able to slide in and out of the tube cutting frame, and the tube drop channel and the horizontal tube space being vertically opposite to and connected to the tube rivet box.

[0006] Compared with the prior art, the binding machine of this utility model has the following advantages: the rivet box can slide in and out of the pipe cutting frame, that is, the opening or closing of the rivet box can be done by manual pull-out. In this way, the spring between the pipe box and the frame can be eliminated. When the rivet box is opened, the rivets inside the rivet box will not suddenly fly out. When the rivet box is closed, the rivets that fall behind will not be bounced away. The rivet box is provided with adjacent and connected pipe drop channels and horizontal pipe space above it, which also improves the rivet box's ability to store and collect rivets. This ensures that the cut rivets can fall into the rivet box and will not get stuck on the inner wall of the channel or inside the rivet box.

[0007] Preferably, the cutting mechanism is used to cut the rivet tubes used in the binding machine. The cut rivet tube falls from the tube drop channel into the rivet tube box, or the cut rivet tube falls from the tube drop channel and passes through the horizontal tube space into the rivet tube box. With this structure, the cut rivet tubes can fall into the rivet tube box through the tube drop channel, and can be tilted in the horizontal tube space until they fall horizontally into the rivet tube box. That is, all the cut rivet tubes can fall from the tube drop channel and lie horizontally in the rivet tube box, without having to remove each rivet tube immediately after it falls down.

[0008] Preferably, the rivet box includes a straight-line storage section, one end of which is configured as a first connecting section. When the rivet box is closed, the first connecting section and the storage section are used to receive the rivet cut off by the cutting mechanism. With this structure, when the rivet box is closed, the lower end of the fallen rivet will fall into the first connecting section, and then tilt and slide across the horizontal tube space until it falls horizontally into the storage section. In this way, the horizontal tube space and the width of the rivet box can be fully utilized, giving the rivet enough space to tilt. The cylindrical rivet will naturally roll into the storage section under the action of gravity.

[0009] Preferably, the rivet box further includes a second connecting part, which is located behind the first connecting part and perpendicular to and communicates with the pipe storage part. With this structure, when the rivet box is in the open state, the pipe storage part, including the first connecting part, is completely exposed outside the pipe cutting frame, while the second connecting part remains inside the pipe cutting frame and below the pipe drop channel. This avoids the rivet box from completely detaching from the pipe cutting frame when opened, which would make closing the rivet box difficult.

[0010] Preferably, a connecting rod is slidably disposed within the pipe drop channel, and a connecting support is connected to the lower end of the connecting rod. The connecting rod is used to drive the connecting support to rise and fall within the pipe drop channel. An inclined surface is provided on the upper end of the connecting support, which slopes downwards from the first connecting part towards the other end of the storage part. With this structure, the length of the rivet is the distance between the connecting support and the top of the pipe drop channel when the rivet is cut. The cutting length of the rivet can be controlled by setting the position of the connecting support. The lower end of the fallen rivet will first land on the inclined surface at the upper end of the connecting support. The connecting rod drives the connecting support to descend, bringing the lower end of the rivet close to the rivet box. Simultaneously, the rivet tilts and slides towards the lower end of the inclined surface, eventually rolling naturally into and lying horizontally within the storage part. The inclined surface of the connecting support facilitates the tilting of the rivet into the rivet box, preventing the rivet from easily falling off the connecting support. If the second connecting part is provided on this basis, then when the rivet box is closed, the second connecting part is located directly below the connecting rod, and together with the pipe storage part, it matches the cross-section of the pipe cutting frame, thus preventing the cut rivet from falling off the connecting rod and onto the outside of the rivet box because the rivet box cannot completely cover the pipe drop channel.

[0011] Preferably, the inner walls of the left and right sides of the pipe cutting frame are provided with rivet box pull-out slides below the pipe drop channel. Both sides of the rivet box are slidably connected to the corresponding rivet box pull-out slides, allowing the rivet box to slide in and out of the pipe cutting frame along the rivet box pull-out slides. This structure is simple and the rivet box can be pulled out stably.

[0012] Preferably, a rivet box pull-out slide is provided on the inner wall of the bottom of the pipe cutting rack. The bottom of the rivet box is slidably connected to the rivet box pull-out slide, allowing the rivet box to slide in and out of the pipe cutting rack along the rivet box pull-out slide. This structure is simple and the rivet box can be pulled out stably.

[0013] Preferably, the sliding connection structure between the rivet box and the pipe cutting frame is a sliding fit between the guide rail and the slide groove. This structure is simple and allows the rivet box to be pulled out stably.

[0014] Preferably, the pipe cutting mechanism includes a top plate with a pipe inlet. The inner diameter of the pipe inlet is not less than the outer diameter of the pipe used in the binding machine. The pipe inlet is vertically opposite to and connected to the pipe drop channel, allowing the pipe to enter the drop channel. A pipe cutting blade is provided at the top of the pipe cutting frame. The pipe cutting blade can perform linear repetitive motion or rotation, cutting the pipe extending into the drop channel from above. With this structure, since the pipe inlet is vertically opposite to and connected to the drop channel, when the pipe falls from the drop channel into the pipe box, the lower end of the pipe will land on one side of the pipe box, making full use of the horizontal pipe space and the width of the pipe box, allowing the pipe sufficient space to tilt.

[0015] Preferably, the top of the pipe cutting frame is provided with a pipe cutting groove, and the pipe cutting blade is set in the pipe cutting groove. The pipe cutting blade can move repeatedly in a straight line along the pipe cutting groove to cut the rivet pipe extending into the pipe dropping channel above the pipe dropping channel. With this structure, the structure is simple, and the pipe cutting blade can be driven by a linear motor or a lead screw, or it can be a manual handle. Attached Figure Description

[0024] like Figure 1 and Figure 2As shown, the binding machine of this utility model includes a tube cutting frame 3. The upper part of the tube cutting frame 3 is provided with a tube drop channel 3-2 and a horizontal tube space 3-4 that are adjacent to each other and connected. The lower part of the tube cutting frame 3 is provided with a riveting box 6. The tube drop channel 3-2 and the horizontal tube space 3-4 are both vertically opposite to and connected to the riveting box 6. The inner sidewalls on the left and right sides of the tube cutting frame 3 are provided with riveting box pull-out slides 3-3 below the tube drop channel 3-2. The riveting box pull-out slides 3-3 are sliding grooves. The two sides of the riveting box 6 are provided with sliding strips that slide and cooperate with the riveting box pull-out slides 3-3 on the corresponding sides. The riveting box 6 can slide in and out of the tube cutting frame 3 along the riveting box pull-out slides 3-3. A connecting pipe support rod 4 is installed in the pipe drop channel. The lower end of the connecting pipe support rod 4 is connected to a connecting pipe support 5. The rivet pipe inlet 1-1 is vertically opposite to the connecting pipe support 5. The connecting pipe support rod 4 is used to drive the connecting pipe support 5 to move up and down in the pipe drop channel 3-2. The upper end of the connecting pipe support 5 is provided with an inclined surface. The high end of the inclined surface is located above the end of the rivet pipe box 6 opposite to the rivet pipe inlet 1-1, and the low end of the inclined surface is opposite to the other end of the rivet pipe box 6.

[0025] The top of the pipe cutting frame 3 is equipped with a pipe cutting mechanism, which includes a top plate 1. The top plate 1 is provided with a rivet pipe inlet 1-1. The inner diameter of the rivet pipe inlet 1-1 is not less than the outer diameter of the rivet pipe used in the binding machine. The rivet pipe inlet 1-1 is vertically connected to the pipe drop channel 3-2, which is used to allow the rivet pipe to enter the pipe drop channel 3-2. The top of the pipe cutting frame 3 is provided with a pipe cutting groove 3-1. A pipe cutting knife 2 is provided in the pipe cutting groove 3-1. The pipe cutting knife 2 can move repeatedly in a straight line along the pipe cutting groove 3-1, which is used to cut the rivet pipe extending into the pipe drop channel 3-2 above the pipe drop channel 3-2. The cut rivet pipe can fall vertically into the rivet pipe box 6, and the vertical rivet pipe can tilt in the horizontal pipe space 3-4 and fall horizontally into the rivet pipe box 6.

[0026] like Figure 3 and Figure 4 As shown, the rivet box 6 includes a straight-line storage section 6-3 and a second connecting section 6-2 vertically disposed at one end of the storage section 6-3. One end of the storage section 6-3 is configured as a first connecting section 6-1, and the second connecting section 6-2 is connected to the first connecting section 6-1 front to back. When the rivet box 6 is closed, the rivet inlet 1-1 is vertically opposite to the first connecting section 6-1. When the rivet box 6 is opened until the storage section 6-3 is fully exposed, the rivet inlet 1-1 is vertically opposite to the second connecting section 6-2.

[0027] In other embodiments, the pipe cutter 2 may also rotate below the rivet inlet 1-1 to cut the rivet extending into the pipe drop channel 3-2.

[0028] In other embodiments, a rivet box pull-out slide can be provided on the inner wall of the bottom of the pipe cutting frame 3, so that the bottom of the rivet box 6 is slidably connected with the rivet box pull-out slide, and the rivet box 6 can also slide in and out of the pipe cutting frame 3 along the rivet box pull-out slide.

[0029] The binding machine of this utility model also includes a frame, with the tube cutting frame 3 and the tube cutting mechanism all mounted on the frame.
