Description

Technical Field

[0001] This utility model relates to the field of chain braiding machine technology, and in particular to a material stopping device for a chain braiding machine. Background Technology

[0002] A chain braiding machine is a mechanical device that braids bar stock into chain links. When the bar stock is fed into the chain braiding machine, it is positioned by impacting a stop device.

[0003] Currently, the material stopping device used on chain braiding machines mainly consists of a hydraulic cylinder and a long rod. The hydraulic cylinder is installed on the material stopping side of the chain braiding machine, and the piston rod of the hydraulic cylinder is connected to the long rod. The piston rod of the hydraulic cylinder extends first, and then the bar stock is fed into the chain braiding machine. When the bar stock collides with the long rod, the bar stock is hooked and locked by the chain braiding machine. Afterward, the piston rod of the hydraulic cylinder retracts, providing space for the bar stock to be braided into chain links.

[0004] Because the hydraulic cylinder and the long rod form a rigid structure, when the bar stock hits the long rod, the bar stock is prone to rebound, causing the bar stock feeding position to deviate. Utility Model Content

[0005] To facilitate the positioning of bar stock, this application provides a material stopping device for a chain braiding machine.

[0006] The material stopping device for a chain braiding machine provided in this application adopts the following technical solution: A material stopping device for a chain braiding machine includes a fixed base, a piston cylinder fixedly mounted on the fixed base, a locking screw fixedly mounted on the output shaft of the piston cylinder, a set of locking nuts, an adjusting seat, and an impact seat sleeved on the locking screw, the locking nuts being threadedly connected to the locking screw, the adjusting seat and the impact seat being slidably connected to the locking screw, the adjusting seat and the locking nuts being located between the impact seat and the piston cylinder, the adjusting seat being located between the locking nuts, the opposite surface of the locking nuts being used to abut against the end wall of the adjusting seat, a telescopic spring being provided between the impact seat and the adjusting seat, and an impact rod being provided on the impact seat.

[0007] By adopting the above technical solution, the fixed seat is installed on the material stop side of the chain braiding machine. The distance between the impact seat and the adjusting seat is adjusted by rotating the locking nut, thereby adjusting the force of the telescopic spring on the impact seat. First, the output shaft of the piston cylinder extends, and then the bar is fed into the chain braiding machine. At this time, the impact seat moves away from the adjusting seat under the action of the telescopic spring. When the bar is fed into the chain braiding machine and touches the impact rod, the impact rod is forced to move the impact seat along the locking screw. When the impact seat stops moving, the chain braiding machine hooks and locks the bar. Then the output shaft of the piston cylinder retracts, driving the locking screw, adjusting seat, impact seat and impact rod to move away, providing clearance space for the bar to be braided into chain links. When the bar impacts the impact rod, the impact rod is forced to move the impact seat along the locking screw, reducing the rebound of the bar.

[0008] Preferably, the telescopic spring is sleeved on the locking screw.

[0009] By adopting the above technical solution, the bending and tangling of the telescopic spring can be reduced.

[0010] Preferably, both the adjusting seat and the impact seat have through locking holes, the locking screw passes through the locking holes, the diameter of the locking screw is smaller than the inner diameter of the locking holes, and the diameter of the inscribed circle of the locking nut is larger than the inner diameter of the locking holes.

[0011] By adopting the above technical solution, both the adjusting seat and the impact seat are slidably connected to the locking screw through the locking through hole.

[0012] Preferably, a locking end is fixedly provided at the end of the locking screw away from the piston cylinder. The diameter of the locking end is larger than the inner diameter of the locking through hole. The locking end is used to abut against the side of the impact seat away from the adjusting seat.

[0013] By adopting the above technical solution, the locking end limits the impact seat, reducing the possibility of the impact seat slipping off the locking screw. When the output shaft of the piston cylinder retracts, the telescopic spring abuts the impact seat against the locking end, and the locking end pushes the impact seat to move.

[0014] Preferably, a guide groove is provided on the fixed base, and an adjusting slider and an impact slider are slidably arranged in the guide groove. The adjusting slider is fixedly connected to the adjusting base, and the impact slider is fixedly connected to the impact base.

[0015] By adopting the above technical solution, the adjusting seat is slidably connected to the fixed seat through the adjusting slider that slides in the guide groove, and the impact seat is slidably connected to the fixed seat through the impact slider that slides in the guide groove.

[0016] Preferably, a limiting slide groove is provided in the guide slide groove, and a set of limiting sliders are slidably arranged in the limiting slide groove, wherein one of the limiting sliders is fixedly connected to the adjusting slider, and the other limiting slider is fixedly connected to the impact slider.

[0017] By adopting the above technical solution, both the adjusting slider and the impact slider are slidably connected to the fixed seat through the limiting slider.

[0018] Preferably, a connecting screw hole is provided on the end of the impact rod away from the piston cylinder, and a connecting bolt is connected to the connecting screw hole by internal thread, and an impact end is fixedly provided on the connecting bolt.

[0019] By adopting the above technical solution, the bar stock applies force to the impact rod through the impact end. The impact end is detachably connected to the impact rod through connecting bolts, which facilitates the replacement of the impact end.

[0020] Preferably, the impact seat has a through-hole for impact, and an impact screw is inserted into the through-hole. A limiting end is fixedly provided at the end of the impact screw near the piston cylinder. The diameter of the limiting end is larger than the inner diameter of the impact through-hole. The end of the impact screw away from the piston cylinder is fixedly connected to the end of the impact rod near the piston cylinder. A set of impact nuts is threaded onto the impact screw. The diameter of the inscribed circle of the impact nuts is larger than the inner diameter of the impact through-hole. The opposite surfaces of the impact nuts are used to abut against the side wall of the impact seat.

[0021] By adopting the above technical solution, the stop position of the bar stock can be finely adjusted by rotating the adjusting nut.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a fixed seat, piston cylinder, locking screw, locking nut, adjusting seat, impact seat, telescopic spring and impact rod, when the bar stock impacts the impact rod, the impact rod is forced to move the impact seat along the locking screw, reducing the rebound of the bar stock; 2. By setting connecting screw holes, connecting bolts, and impact ends, the impact end can be easily replaced; 3. The stop position of the bar stock is finely adjusted by setting an impact through hole, an impact screw, a limit end, and an impact nut. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0029] This application discloses a material stopping device for a chain braiding machine. (Refer to...) Figure 1 and Figure 2 The chain bracing machine includes a fixed base 1, which is installed on the material stop side. A piston cylinder 2 is mounted on the fixed base 1, and a locking screw 3 is mounted on the output shaft of the piston cylinder 2. A locking end 33 is mounted on the end of the locking screw 3 away from the piston cylinder 2. A set of locking nuts 31, an adjusting seat 4, and an impact seat 5 are fitted onto the locking screw 3. The locking nuts 31 are threadedly connected to the locking screw 3, and the adjusting seat 4 and the impact seat 5 are slidably connected to the locking screw 3. An impact rod 7 is mounted on the impact seat 5, and the side of the impact seat 5 away from the adjusting seat 4 is used to abut against the locking end 33. The adjusting seat 4 and the locking nuts 31 are both located between the impact seat 5 and the piston cylinder 2, with the adjusting seat 4 located between the locking nuts 31. The opposite face of the locking nuts 31 is used to abut against the end wall of the adjusting seat 4. A telescopic spring 6 is installed between the impact seat 5 and the adjusting seat 4, and the telescopic spring 6 is fitted onto the locking screw 3 to reduce the bending and entanglement of the telescopic spring 6. Rotating the locking nut 31 adjusts the distance between the impact seat 5 and the adjusting seat 4, thereby adjusting the force exerted by the telescopic spring 6 on the impact seat 5. Before the bar stock is fed into the chain braiding machine, the output shaft of the piston cylinder 2 extends first, and then the bar stock is fed into the chain braiding machine. At this time, the impact seat 5 moves away from the adjusting seat 4 under the action of the telescopic spring 6. When the bar stock is fed into the chain braiding machine and contacts the impact rod 7, the impact rod 7 is forced to move the impact seat 5 along the locking screw 3. When the impact seat 5 stops moving, the chain braiding machine hooks and locks the bar stock. Afterward, the output shaft of the piston cylinder 2 retracts, and the telescopic spring 6 presses the impact seat 5 against the locking end 33. The locking end 33 pushes the impact seat 5 to move, thereby moving the locking screw 3, adjusting seat 4, impact seat 5, and impact rod 7 away, providing clearance space for the bar stock to be braided into chain links. When the bar stock impacts the impact rod 7, the impact rod 7 is forced to move the impact seat 5 along the locking screw 3, reducing the rebound of the bar stock.

[0030] Reference Figure 1 and Figure 2 Both the adjusting seat 4 and the impact seat 5 have a through-hole 32, through which the locking screw 3 passes. The diameter of the locking screw 3 is smaller than the inner diameter of the locking through-hole 32, the diameter of the inscribed circle of the locking nut 31 is larger than the inner diameter of the locking through-hole 32, and the diameter of the locking end 33 is larger than the inner diameter of the locking through-hole 32. Both the adjusting seat 4 and the impact seat 5 are slidably connected to the locking screw 3 through the locking through-hole 32. The locking end 33 limits the impact seat 5, reducing the possibility of the impact seat 5 slipping off the locking screw 3.

[0031] Reference Figures 1 to 3A guide groove 11 is formed on the fixed base 1, and a limiting groove 12 is formed within the guide groove 11. A set of limiting sliders 121 are slidably arranged within the limiting groove 12. An adjusting slider 41 is welded to one of the limiting sliders 121, and the adjusting slider 41 is welded to the adjusting base 4. An impact slider 51 is welded to the other limiting slider 121, and the impact slider 51 is welded to the impact base 5. Both the adjusting slider 41 and the impact slider 51 are slidably connected to the fixed base 1 through the limiting sliders 121. The adjusting base 4 is slidably connected to the fixed base 1 through the adjusting slider 41 sliding within the guide groove 11, and the impact base 5 is slidably connected to the fixed base 1 through the impact slider 51 sliding within the guide groove 11.

[0032] Reference Figure 1 and Figure 4 A connecting screw hole 73 is provided on the end of the impact rod 7 away from the piston cylinder 2. A connecting bolt 72 is connected to the internal thread of the connecting screw hole 73, and an impact end 71 is installed on the connecting bolt 72. The bar stock applies force to the impact rod 7 through the impact end 71. The impact end 71 is detachably connected to the impact rod 7 through the connecting bolt 72, so as to facilitate the replacement of the impact end 71.

[0033] Reference Figure 1 and Figure 4 An impact through hole 81 is provided through the impact seat 5, and an impact screw 8 is inserted into the impact through hole 81. A limiting end 83 is installed on the end of the impact screw 8 near the piston cylinder 2. The diameter of the limiting end 83 is larger than the inner diameter of the impact through hole 81. The end of the impact screw 8 away from the piston cylinder 2 is welded to the end of the impact rod 7 near the piston cylinder 2. A set of impact nuts 82 are threadedly connected to the impact screw 8. The diameter of the inscribed circle of the impact nuts 82 is larger than the inner diameter of the impact through hole 81. The opposite surfaces of the impact nuts 82 are used to abut against the side wall of the impact seat 5. The stop position of the bar stock can be finely adjusted by rotating the adjusting nut.

[0034] The implementation principle of the material stopping device for a chain braiding machine according to an embodiment of this application is as follows: Before the bar stock is fed into the chain braiding machine, the output shaft of the piston cylinder 2 extends first, and then the bar stock is fed into the chain braiding machine. At this time, the impact seat 5 moves away from the adjusting seat 4 under the action of the telescopic spring 6. When the bar stock is fed into the chain braiding machine and contacts the impact rod 7, the impact rod 7 is forced to move the impact seat 5 along the locking screw 3. When the impact seat 5 stops moving, the chain braiding machine hooks and locks the bar stock. Afterwards, the output shaft of the piston cylinder 2 retracts, and the telescopic spring 6 abuts the impact seat 5 against the locking end 33. The locking end 33 pushes the impact seat 5 to move, thereby moving the locking screw 3, adjusting seat 4, impact seat 5, and impact rod 7 away, providing clearance space for the bar stock to be braided into chain links. When the bar stock impacts the impact rod 7, the impact rod 7 is forced to move the impact seat 5 along the locking screw 3, reducing the rebound of the bar stock.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
