[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a buffer structure for a packaging machine door, comprising: a buffer component 1 for slowing down the door closing speed and playing a buffering role, and a mounting base 2 for facilitating the disassembly and maintenance of the buffer component 1 is provided on one side of the buffer component 1.

[0024] The buffer assembly 1 comprises: a U-shaped mounting plate 17, one side of the U-shaped mounting plate 17 is rotatably connected to the outside of the rolling wheel 18, the other side of the U-shaped mounting plate 17 is rotatably connected to one end of two groups of oblique push plates 16, the two groups of oblique push plates 16 are symmetrically arranged, the other ends of the two groups of oblique push plates 16 are respectively rotatably connected to one side of two groups of sliding blocks 15, the insides of the two groups of sliding blocks 15 are slidably sleeved on the outsides of the two groups of guide rods 14, and the outsides of the two ends of the guide rods 14 are slidably inserted into the inner ring of the buffer spring 19. Both ends of the two groups of guide rods 14 are fixedly connected to both sides of the support plate 13, one end of the buffer spring 19 is fixedly connected to one side supported by the sliding block 15, and the other end of the buffer spring 19 is fixedly connected to the side of the support plate 13. One side of the support plate 13 is fixedly connected to one side of the connecting plug plate 12, and a positioning plug hole 11 is provided on the top of the connecting plug plate 12.

[0025] Furthermore, when the buffer assembly 1 is installed, during the door closing process, the door panel will push the rolling wheel 18 to move in the direction of the support plate 13, and the rolling wheel 18 will push the U-shaped mounting plate 17, and the U-shaped mounting plate 17 will push the two sets of sliding blocks 15 away from each other through two sets of oblique push plates 16. During the process of the two sets of sliding blocks 15 moving away from each other, the buffer spring 19 will be compressed. Under the elastic force of the buffer spring 19, the movement speed of the door panel will be weakened, thereby effectively reducing the impact force between the door and the door frame caused by inertia, reducing noise, avoiding damage to the accuracy of the strapping machine, and ensuring the service life of the machine. When the cabinet door is closed, the cabinet door will be automatically locked by the door lock. After the cabinet door is opened, the buffer spring 19 pushes the two sets of sliding blocks 15 closer to each other, and the two sets of sliding blocks 15 push the U-shaped mounting plate 17 and the rolling wheel 18 back to their original positions through the two sets of oblique push plates 16.

[0026] The mounting base 2 includes a fixing block 23, the side of which is fixedly connected to one side of the positioning plate 21, a slot 24 is provided on one side of the fixing block 23, and the slot wall of the slot 24 is slidably sleeved on the outside of the connecting plug plate 12. A through hole 22 is provided on the top of the fixing block 23, and the top of the fixing block 23 is located at the position of the through hole 22 and fixedly connected to the two ends of the bottom of the U-shaped bracket 27, and the top of the U-shaped bracket 27 is slidably sleeved on the side of the pull rod 26. The top of the pull rod 26 is fixedly connected to the outside of the pull ring 25, and the bottom end of the pull rod 26 is fixedly connected to the top of the positioning pin rod 29, and the side of the positioning pin rod 29 is slidably inserted into the through hole 22 and the hole wall of the positioning plug hole 11. The outside of the pull rod 26 is slidably sleeved on the inner ring of the reset spring 28, and the reset spring 28 is located between the U-shaped bracket 27 and the positioning pin rod 29.

[0027] Furthermore, the positioning plate 21 is fixed to the inner wall of the machine cabinet by screws to achieve the installation and fixation of the entire mounting base 2, and then the buffer assembly 1 is picked up, and the connecting plug plate 12 on one side of the buffer assembly 1 is inserted into the slot 24 on one side of the fixing block 23. Before insertion, the positioning pin rod 29 is lifted upward by the pull ring 25 to pull the positioning pin rod 29 out of the slot 24 to avoid affecting the insertion of the connecting plug plate 12. After the connecting plug plate 12 is fully inserted into the slot 24, the positioning hole 11 will be aligned with the through hole 22. At this time, release the pull ring 25, and the reset spring 28 will push the positioning pin rod 29 to insert into the through hole 22 and the positioning hole 11. In this way, the buffer assembly 1 completes the connection and installation with the mounting base 2. After long-term use and wear, the buffer component 1 may need to be repaired and replaced. In this case, the positioning pin rod 29 needs to be pulled out from the positioning hole 11 through the pull ring 25, and the connecting plate 12 can be pulled out from the slot 24, thereby realizing the disassembly of the buffer component 1. Through the above method, the buffer component 1 is faster and more convenient to disassemble and install, which is conducive to maintenance and replacement.

[0028] Working principle: When in use, first fix the positioning plate 21 to the inner wall of the machine cabinet with screws to achieve the installation and fixation of the entire mounting base 2, then pick up the buffer assembly 1, and insert the connecting plug plate 12 on one side of the buffer assembly 1 into the slot 24 on one side of the fixing block 23. Before insertion, first lift the positioning pin rod 29 upward through the pull ring 25 to pull the positioning pin rod 29 out of the slot 24 to avoid affecting the insertion of the connecting plug plate 12. After the connecting plug plate 12 is fully inserted into the slot 24, the positioning hole 11 will be aligned with the through hole 22. At this time, release the pull ring 25, and the reset spring 28 will push the positioning pin rod 29 to insert into the through hole 22 and the positioning hole 11. In this way, the buffer assembly 1 completes the connection and installation with the mounting base 2.

[0029] When the buffer assembly 1 is installed, during the door closing process, the door panel will push the rolling wheel 18 to move in the direction of the support plate 13, and the rolling wheel 18 will push the U-shaped mounting plate 17, and the U-shaped mounting plate 17 will push the two groups of sliding blocks 15 away from each other through two groups of oblique push plates 16. During the process of the two groups of sliding blocks 15 moving away from each other, the buffer spring 19 will be compressed. Under the elastic force of the buffer spring 19, the movement speed of the door panel will be reduced, thereby effectively reducing the impact force between the door and the door frame caused by inertia, reducing noise, avoiding damage to the accuracy of the strapping machine, and ensuring the service life of the machine.
