Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of office equipment, more particularly to a binding machine with a pipe receiving mechanism. BACKGROUND

[0002] A binding machine is a machine for fixing paper, plastic, leather and the like with binding nails or hot melt glue. The product types of the binding machine are classified according to the binding method, and there are generally hot melt binding machines, certificate binding machines, financial binding machines, punch binding machines, accounting certificate binding machines, comb ring binding machines, iron ring binding machines, and strip binding machines on the market. The hot melt binding machine has the advantages of simple operation, high speed, low material cost, and beautiful style, and is favored by people. The hot melt binding machine includes a punching device, a pipe cutting device, a hot riveting device, and the like. For convenient use, some binding machines are also provided with a pipe receiving mechanism. The pipe receiving mechanism is used to receive the cut rivet pipe and wait for the guide needle to transport the cut rivet pipe to the workbench for riveting. However, the existing binding machine has the following defects: when the pipe cutting height of the existing binding machine is inconsistent with the height of the workbench reversing groove, that is, the height of the workbench reversing groove is lower than the pipe cutting height, the guide needle rotates below the workbench to transfer the cut rivet pipe. Since the workbench has a certain thickness, when the thickness of the paper is relatively thin, the cut rivet pipe is relatively short. At this time, if the guide needle wants to rotate the rivet pipe to the riveting position, the relative distance between the pipe receiving mechanism and the workbench is short, and the guide needle needs to be lifted to a high position to receive the cut rivet pipe. The end of the guide needle is higher than the lower surface of the workbench. At this time, the rotating guide needle will interfere with the workbench, and the rivet pipe cannot be transported to the riveting position, so the binding machine cannot work normally. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a binding machine with a pipe receiving mechanism, which can effectively solve the problem of workbench interference, so that the cut rivet pipe can be smoothly received by the guide needle, and the binding machine can work normally.

[0004] The technical solution of the present application is to provide a binding machine with a pipe receiving mechanism, which has the following structure, including a rack, a workbench, a paper pressing table and a pipe receiving mechanism are arranged on the rack, the pipe receiving mechanism includes a pipe receiving assembly, a rope and a winding and unwinding assembly, one end of the rope is connected to the pipe receiving assembly, the other end of the rope is connected to the paper pressing table, and the middle part of the rope is wound on the winding and unwinding assembly; before cutting the glue pipe, the winding and unwinding assembly winds up the set length of the rope; after cutting the glue pipe, the winding and unwinding assembly unwinds the set length of the rope to one side of the pipe receiving assembly.

[0005] After adopting the above structure, the binding machine with a pipe receiving mechanism of the present application has the following advantages compared with the prior art:

[0006] Because the binding machine of the present invention with a tube holder mechanism includes a take-up and release component, before cutting the tube, the take-up and release component retracts a rope of a set length; after cutting the tube, the take-up and release component releases the rope of the set length to one side of the tube holder component. At this time, the position of the tube holder component is lower than that of the worktable compared to before the tube, so the guide pin does not need to be raised to a higher position to catch the cut tube, and the guide pin can also rotate smoothly to catch the cut tube without interfering with the worktable, so that the binding machine can work normally.

[0007] As an improvement, the take-up and release assembly is located at the upper end of the frame, above the paper feeder assembly and the paper pressing table. This structure is simple and rationally designed.

[0008] As an improvement, the retraction / release assembly includes a drive component, a swing arm, and a support component. The drive component drives the swing arm to swing. The rope, after being connected to the paper pressing table, passes sequentially around the swing arm and the support component before connecting to the take-up connector assembly. When the swing arm swings towards the support component, it can retract the rope of a predetermined length; when the swing arm swings away from the support component, it can release the rope of the predetermined length towards the take-up connector assembly. With this structure, the retraction / release assembly is simple in structure, and the rope retraction / release is more convenient.

[0009] As an improvement, the end of the swing arm is provided with an anti-detachment bracket, which is used to limit the rope to the end of the swing arm. With this structure, the anti-detachment bracket can limit the rope to the end of the swing arm, preventing the rope from detaching from the end of the swing arm.

[0010] As an improvement, both ends of the anti-detachment bracket are connected to the side wall of the swing rod, and a rope-threading hole is formed between the anti-detachment bracket and the swing rod, through which the rope passes. With this structure, the anti-detachment bracket is simple in design and provides good anti-detachment effect.

[0011] As an improvement, the anti-detachment bracket consists of two limiting posts, each located on one side of the end of the swing arm. A cable passage groove is formed between the two limiting posts and the swing arm, through which the rope passes. This structure results in a simple anti-detachment bracket with good anti-detachment performance.

[0012] As an improvement, the anti-detachment bracket is located on the side of the swing arm near the connecting pipe support assembly. This structure allows for better control of the length of the retractable rope.

[0013] As an improvement, the support member is located below the anti-slip bracket. With this structure, the anti-slip bracket and the support member work together to better control the length of the retracted rope.

[0014] As an improvement, the frame is provided with a fixed plate, and the support member is mounted on the fixed plate; the fixed plate is provided with a mounting bracket, and the drive member is fixedly connected to the mounting bracket; the two ends of the fixed plate are respectively provided with a first through hole and a second through hole, and the rope passes through the first through hole, passes around the swing arm and the support member in sequence, and then exits through the second through hole. With this structure, the installation structure of the drive member and the support member is simple and easy to assemble, and the first and second through holes can limit the rope and prevent the rope from moving.

[0015] As an improvement, the support member has an inverted "L" shape, with the rope resting on the underside of the crossbar of the support member. This structure simplifies the support member design and provides good rope restraint.

[0016] As an improvement, a code disk is connected to the lower side of the swing arm, and the connection between the swing arm and the code disk is connected to the drive end of the drive component. A photoelectric sensor is provided below the code disk, and the photoelectric sensor is fixedly connected to the fixed plate. This photoelectric sensor is used to monitor the rotational stroke of the code disk. With this structure, the photoelectric sensor monitors the rotational stroke of the code disk, thereby enabling the monitoring of the swing arm's swing stroke.

[0017] As an improvement, the pipe support assembly includes a guide post and a pipe support. A guide hole is provided on the worktable, the guide post is slidably fitted within the guide hole, and its lower end protrudes from the lower side of the worktable. The pipe support is connected to the lower end of the guide post; the pipe support is located below the pipe drop hole on the worktable. With this structure, the pipe support assembly is simple in structure and easy to assemble.

[0018] As an improvement, the connecting pipe support is provided with a notch directly below the drop-in hole, allowing the guide pin to pass through. This design simplifies the connection between the connecting pipe support and the guide pin.

[0019] As an improvement, a mounting base is provided on the workbench, and a hollow guide tube is provided on the mounting base. The guide tube is aligned with the guide hole, and the guide post is slidably fitted inside the guide tube. With this structure, the structure is simple, assembly is convenient, and the guide post installation is more stable.

[0020] As an improvement, the mounting base is equipped with a pipe cutter and a pipe rivet hole, the pipe rivet hole being aligned with the pipe drop hole, and the pipe cutter capable of cutting the rivet horizontally. With this structure, both the guide post and the pipe cutter are mounted on the mounting base, resulting in a simple and compact structure. Attached Figure Description

The photoelectric sensor 11 is used to monitor the rotational stroke of the code disk 10, thereby determining the swing stroke of the swing arm 7.

[0034] The end of the swing arm 7 is provided with an anti-detachment bracket 12, which is used to limit the rope 4 to the end of the swing arm 7. Both ends of the anti-detachment bracket 12 are connected to the side wall of the swing arm 7, and a rope hole 1201 is formed between the anti-detachment bracket 12 and the swing arm 7, through which the rope 4 passes. The anti-detachment bracket 12 can also be other structures, such as two limiting posts, which are respectively provided on both sides of the end of the swing arm 7, forming a cable groove between the two limiting posts and the swing arm 7, through which the rope 4 passes. In this specific embodiment, the anti-detachment bracket 12 is provided on the side of the swing arm 7 near the connecting pipe support assembly.

[0035] The support member 8 is mounted on the fixed plate 5 and is located below the anti-detachment bracket 12.
