Description

Technical Field

[0001] This application belongs to the field of tube cutting control technology for binding, and in particular relates to a tube cutting control mechanism and a binding machine equipped with the control mechanism. Background Technology

[0002] The current binding machine uses a tube feeding motor to control the feeding of the binding tube. For binding machines with limited space, this control method not only occupies more equipment space, but also requires more parts to cooperate with it, resulting in a complex structure and inconvenient installation and operation. Summary of the Invention

[0003] This application provides a tube cutting control mechanism and a binding machine, which solves the technical problems of the existing tube cutting control mechanism having a complex structure and inconvenient installation and operation.

[0004] To solve at least one of the above-mentioned technical problems, the technical solution adopted in this application is:

[0005] A pipe cutting control mechanism, comprising:

[0006] The feeding pipe is vertically installed on the outside of the frame, and has holes on the side wall of its lower section.

[0007] A magnetic suction assembly, disposed beside the feed tube, includes a magnetic coil and a push rod arranged axially along the magnetic coil, the top of the push rod being positioned corresponding to the hole;

[0008] The top rod can be attracted by the magnetic coil during tube cutting and detach from the binding tube placed in the feeding tube, allowing the cut binding tube to fall freely. When not cutting the tube, it can disconnect from the magnetic coil, pass through the hole, and abut against the binding tube to fix its position.

[0009] Furthermore, the push rod is constructed as a long cylindrical structure, and a stop pad is provided at one end near the hole. The distance from the stop pad to the end of the push rod is greater than the wall thickness of the feed tube.

[0010] Furthermore, the stop pad can be designed as a circular, triangular, or polygonal structure; the stop pad is penetrated by the top rod, and the circumscribed circle diameter of the stop pad is larger than the minimum diameter of the hole.

[0011] Furthermore, an elastic element is provided between the stop pad and the end of the magnetic coil, and the elastic element is sleeved on the outer wall of the top rod; the magnetic coil is designed as a circular coil and is fixed to the outside of the frame.

[0012] Furthermore, the hole can be constructed as a circular or elliptical structure, with its center position aligned with the axis height of the magnetic coil.

[0013] Furthermore, it also includes a material dragging assembly, including a material support plate suspended below the feeding pipe and a flexible connector for connecting the material support plate to the pressure plate. One end of the connector is connected to the side of the pressure plate near the feeding pipe, and the other end passes through the top of the frame and is connected to the material dragging plate.

[0014] When the pressure plate descends, the connecting piece can drive the support plate to rise, and the support plate will stop at the height of one end of the feeding tube to support the cut binding tube.

[0015] Furthermore, the drag plate is constructed in an L-shape, with its vertical section passing through a horizontal plate used to fix the feed tube, and connected to the connector via a guide tube placed on the horizontal plate.

[0016] Furthermore, the cross-section of the vertical section in the drag plate is constructed as a non-circular structure, and the inner wall of the guide cylinder is adapted to the vertical section in the drag plate.

[0017] Furthermore, a wire guide bracket for adjusting the guide path of the connecting piece is installed at the upper end of the feeding tube. The wire guide bracket is provided with a through hole through which the connecting piece passes. The through hole corresponds vertically to the vertical section of the drag plate. The through hole is located at the end of the wire guide bracket away from the feeding tube.

[0018] A binding machine is equipped with the control mechanism described above.

[0019] The tube-cutting control mechanism designed in this application adopts a magnetic control method, which can quickly push against the side of the binding tube when not cutting the tube, and can also accurately retract when cutting the tube, so that the cut binding tube falls down; at the same time, it also adopts a wire control method to support the cut binding tube, which is simple in structure and easy to operate.

[0033] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0034] This embodiment proposes a tube-cutting control mechanism, such as... Figure 1-2 As shown, the device includes a frame 10, a feeding tube 20, a magnetic suction assembly 30 for controlling the binding tube placed inside the feeding tube 20, a material pulling assembly 40 for receiving the cut binding tube, and a pressure plate 60 for pressing the paper before drilling. The lower end face of the feeding tube 20 is fixed to a horizontal plate 50 connected to the frame 10, and the magnetic suction assembly 30 is located on the horizontal plate 50. The material pulling assembly 40 is located on the side of the feeding tube 20 away from the magnetic suction assembly 30, and the pressure plate 60 is located diagonally below the feeding tube 20.

[0035] Specifically, the feeding tube 20 is vertically positioned on the outside of the frame 10, and a hole 21 is provided on the side wall of its lower section, with the hole 21 located on the side of the feeding tube 20 closest to the magnetic suction assembly 30. The hole 21 can be constructed as a circle or an ellipse, and its center position must be aligned with the axis of the magnetic coil 31 in the magnetic suction assembly 30. Preferably, holes 21 are provided on both sides of the lower section of the feeding tube 20, that is, the holes 21 pass through the side walls of the feeding tube 20, which facilitates observation of the position of the top rod 32 in the magnetic suction assembly 30 against the binding tube, and also facilitates maintenance and processing.

[0036] like Figure 3As shown, the magnetic suction assembly 30 is disposed beside the feeding tube 20, including a magnetic coil 31 and a push rod 32 arranged axially in the magnetic coil 31. The top of the push rod 32 is positioned corresponding to the hole 21. The push rod 32 is constructed as a long cylindrical structure, and a stop pad 34 is integrally welded to the body of the push rod 32 at one end near the hole 21. The distance from the stop pad 34 to the end of the push rod 32 near the hole 21 is greater than the wall thickness of one side of the feeding tube 20. The purpose is that when the stop pad 34 contacts the outer wall surface of the feeding tube 20, the top of the protruding push rod 32 can contact and abut against the binding tube.

[0037] Furthermore, the stop pad 34 can be designed as a circular, triangular, or polygonal structure, which is penetrated by the body of the top rod 32, and the diameter of its circumscribed circle is larger than the minimum diameter of the hole 21, in order to limit the length of the top rod 32 embedded in the hole 21. An elastic element 33 is also provided between the stop pad 34 and the end of the magnetic coil 31; preferably, this elastic element 33 is a spring. The elastic element 33 is sleeved on the outer wall of the top rod 32, and after the top rod 32 is attracted and compressed by the magnetic coil 31, it can spring back to its position against the binding tube after the power is cut off. The magnetic coil 31 is designed as a circular coil, which is fixed to the horizontal plate 50 on the outside of the frame 10, and the horizontal plate 50 is directly connected to the frame 10.

[0038] During the tube cutting process, the push rod 32 can be attracted by the magnetic coil 31 and detach from the binding tube placed in the feeding tube 20, allowing the cut binding tube to fall freely. It can also disconnect from the magnetic coil 31 when not cutting, and be driven by the elastic element 33 to rebound to its initial position, passing through the hole 21 and abutting the binding tube to fix its position. Using a magnetic control method, it can quickly abut the side of the binding tube when not cutting, and can also precisely retract during cutting, allowing the cut binding tube to fall. The structure is simple and the operation is convenient. How the tube is cut is not the focus of this case and is omitted here.

[0039] like Figure 4-6 As shown, the material feeding assembly 40 includes a material support plate 41 suspended below the feeding pipe 20 and a flexible connector 42 for connecting the material support plate 41 to the pressure plate 60. In this embodiment, the flexible connector 42 is a nylon thread. One end of the connector 42 is connected to the side of the pressure plate 60 near the feeding pipe 20, and the other end passes through the top of the frame 10 and is then connected to the material feeding plate 41.

[0040] Furthermore, the material support plate 41 is constructed in an L-shape, with its vertical section passing through the horizontal plate 50 used to fix the feeding tube 20, and connected to the connector 42 via a guide cylinder 44 placed on the horizontal plate 50. The guide cylinder 44 is fixedly mounted on the horizontal plate 50 and is located on the side of the feeding tube 20 away from the magnetic coil 31.

[0041] Furthermore, the cross-section of the vertical section of the material support plate 41 is constructed as a non-circular structure. This facilitates the positioning of the vertical position of the material support plate 41, preventing it from rotating within the guide cylinder 44. Simultaneously, it positions the horizontal section of the material support plate 41, ensuring that it is always horizontally positioned facing the magnetic coil 31 and directly below the feeding tube 20. In this embodiment, the cross-section of the vertical section of the material support plate 41 is square or rectangular; it can also be constructed as a polygon, as long as its position can be defined. Correspondingly, the inner wall of the guide cylinder 44 is adapted to the cross-section of the vertical section of the material support plate 41.

[0042] Furthermore, a wire guide bracket 43 for adjusting the guide path of the connector 42 is installed at the upper end of the feeding pipe 20. One end of the bracket is fixed to the feeding pipe 20, and the other end is suspended. The wire guide bracket 43 has a through hole through which the connector 42 passes. This through hole is located at the end of the wire guide bracket 43 away from the feeding pipe 20, i.e., at the suspended end of the wire guide bracket 43. There can be at least one or more of these through holes to ensure that the connector 42, when wound downwards, corresponds vertically to the vertical section of the drag plate 41, ensuring smooth up-and-down movement of the drag plate 41.

[0043] The pressure plate 60 is equipped with a drilling motor 70, which is controlled by a lifting motor 80 fixed in the frame 10 to move up and down. This structure is a common structure in the field and is omitted here.

[0044] During the binding process, when the pressure plate 60 is driven to descend by the lifting motor 80, it can drive the support plate 41 to move upward through the connecting piece 42, and make the support plate 41 stop at the height of one end of the feeding tube 20 to support the cut binding tube. The use of a wire control method to support the cut binding tube is simpler in structure, has lower production cost, and is easy to disassemble.

[0045] A binding machine is equipped with the control mechanism described above.

[0046] The tube-cutting control mechanism designed in this application adopts a magnetic control method, which can quickly push against the side of the binding tube when not cutting the tube, and can also accurately retract when cutting the tube, so that the cut binding tube falls down; at the same time, it also adopts a wire control method to support the cut binding tube, which is simple in structure and easy to operate.

[0047] The embodiments of this application have been described in detail above. These descriptions are merely preferred embodiments and should not be construed as limiting the scope of this application. All equivalent variations and modifications made within the scope of this application should still fall within the patent coverage of this application.
