[0017] Figure 4 for Figure 3 A magnified perspective view of point A in the image. Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figures 1 to 4 As shown, this utility model's pen holder knurling mechanism includes a worktable 1 and a feeding bin 2, which can be mounted on the worktable 1 via a bracket. The worktable 1 has a base 3, a guide rail 4, a movable seat 5, and a moving motor 6. The movable seat 5 has a first cylinder 7, a fixed seat 8, and a mounting component 9. The mounting component 9 has a knurling component 10.

[0020] During the knurling process, the first cylinder 7 first pushes the knurling part 10 close to the pen holder 11, and then the moving motor 6 is started, driving the screw 12 on the moving motor 6. The screw 12 is installed on the moving seat 5, so that the moving seat 5 moves along the guide rail 4, thereby causing the knurling part 10 to move and knurl the outer wall of the pen holder 11 for a certain distance.

[0021] The feeding bin 2 is set on the workbench 1. A feeding plate 13 is provided at the lower end of the feeding bin 2. A second cylinder 14 is provided at one end of the feeding plate 13. The second cylinder 14 is installed on the workbench 1. A rolling element 15 is provided on the feeding plate 13. The rolling element 15 is provided with a feeding groove 16 that cooperates with the feeding bin 2. Symmetrically arranged hinge blocks 17 are provided on the feeding plate 13. A hinge shaft 18 is provided on the hinge block 17. The rolling element 15 is installed on the hinge shaft 18. The knurled part 10 can rotate on the feeding plate 13.

[0022] To ensure the rotation angle of the knurled part 10, the rolling part 15 rotates at an angle of 90°. The hinge block 17 has a first limiting arc 19 and a second limiting arc 20. The rolling part 15 has a first limiting rod 21 and a second limiting rod 22. The first limiting rod 21 engages with the first limiting arc 19, and the second limiting rod 22 engages with the second limiting arc 20. The second limiting arc 20 is located at the lower end of the first limiting arc 19. When the knurled part 10 needs to load the pen holder 11 from the unloading bin 2, the first limiting rod 21 is kept within the first limiting arc 19. When the pen holder 11 needs to be knurled, the second limiting rod 22 is kept within the second limiting arc 20.

[0023] Furthermore, a support block 23 is provided on the worktable 1, a toothed plate 24 is provided on the support block 23, a first tooth 25 is provided on the toothed plate 24, and a second tooth 26 that mates with the first tooth 25 is provided on the rolling element 15. The length of the toothed plate 24 is less than the distance the rolling element 15 moves, and the toothed plate 24 is kept at the middle position of the distance the rolling element 15 moves.

[0024] Since the length of the toothed plate 24 is limited, the knurled part 10 makes the rolling part 15 rotate by the first tooth 25 and the second tooth 26. This makes the first limiting rod 21 within the first limiting arc 19, thereby restricting the rolling of the rolling part 15. As the second cylinder 14 moves, it reaches the lower end of the feeding bin 2, and the pen holder 11 in the feeding bin 2 will fall into the feeding trough 16.

[0025] Then, the second cylinder 14 pushes the feeding plate 13, causing it to gradually approach the toothed plate 24. As the first tooth 25 and the second tooth 26 mesh, the rolling element 15 rotates 90°, simultaneously placing the second limiting rod 22 within the second limiting arc 20, thus restricting the position of the rolling element 15. Furthermore, when the rolling element 15 reaches the knurled part 10, the center vertical line of the feeding groove 16 on the rolling element 15 is not vertical, preventing the pen holder 11 from falling. However, the rotating shaft 27 can push it out of the feeding groove 16, thereby causing the pen holder 11 to rotate.

[0026] When the rolling element 15 is engaged with the toothed plate 24, the rolling element 15 rotates; when it is not engaged with the toothed plate 24, the rolling element 15 remains stationary.

[0027] A third cylinder 28 is also provided on the workbench 1. The third cylinder 28 is equipped with a feeding component 29. The feeding component 29 is used to complete the knurling of the pen holder 11. The feeding component 29 catches the pen holder 11 and drives it to move to the lower end of the workbench 1.

[0028] The workbench 1 is also provided with a clearance hole 30, the third cylinder 28 is located at the lower end of the clearance hole 30, and the unloading part 29 extends out from the clearance hole 30.

[0029] The workbench 1 is also equipped with a fourth cylinder 31, a push plate 32 on the fourth cylinder 31, a mounting plate 33 on the push plate 32, a rotary motor 34 on the mounting plate 33, and a rotating shaft 27 on the rotary motor 34. The diameter of the rotating shaft 27 is interference-fitted with the inner diameter of the pen holder 11, so that the rotating shaft 27 is inserted into the pen holder 11 under force. When the rotary motor 34 rotates, it drives the pen holder 11 to rotate through the rotating shaft 27.

[0030] A first baffle 35 and a second baffle 36 are provided on both sides of the clearance hole 30. The rotating shaft 27 is located in the middle of the first baffle 35. The second baffle 36 is provided with an insertion hole 37 that cooperates with the pen holder 11. The insertion hole 37 is not a through hole, thereby restricting the position of the pen holder 11 so that the rotating shaft 27 can be inserted into the pen holder 11.

[0031] During the knurling process of the pen holder 11, the pen holder 11 is first fed through the feeding hopper 2. The second cylinder 14 drives the feeding plate 13 to move, and the pen holder 11 is discharged from the feeding hopper 2 and falls into the feeding trough 16. The second cylinder 14 then moves it to the upper end of the clearance hole 30. Then, the fourth cylinder 31 drives the rotating shaft 27 on the rotary motor 34 to insert into the pen holder 11, so that one end of the pen holder 11 is placed in the insertion hole 37. The rotary motor 34 drives the pen holder 11 to rotate. The first cylinder 7 is started to move the knurling part 10 closer to the outer wall of the pen holder 11. The moving motor 6 drives the first cylinder 7 to move its position, increasing the knurling distance. After the knurling is completed, the fourth cylinder 31 drives the rotating shaft 27 closer to the first baffle 35, so that the first baffle 35 blocks the pen holder 11, causing the pen holder 11 to fall onto the feeding part 29. The third cylinder 28 then moves it to the conveyor chain at the lower end of the worktable 1. When the unloading component 29 does not need to catch the pen holder 11, it is located at the lower end of the conveyor chain. The conveyor chain has multiple holes through which the unloading component 29 passes, allowing it to move freely up and down.

[0032] When the rolling element 15 is at both ends of the toothed plate 24, it is pushed horizontally by the second cylinder 14 so that it will not rotate, which facilitates the loading and unloading of the pen holder 11.

[0033] A limiting member 38 is provided inside the feeding trough 16, and an elastic arm 39 is provided on the limiting member 38. An elastic region 40 is formed between the elastic arm 39 and the inner wall of the feeding trough 16.Figure 4 As shown, when the feeding trough rotates 90°, the pen holder 11 can be moved out of the feeding trough 16. This pushes the elastic arm 39, allowing the pen holder 11 to move out. When rotated 90°, the pen holder 11 can be restricted within the feeding trough 16 by the limiting action of the elastic arm 39, so that when the feeding trough 16 is horizontally set, the pen holder 11 will not fall out of the feeding trough 16.

[0034] Furthermore, a guide section 41 is provided on the elastic arm 39 to guide the pen holder 11 when it enters the feeding trough 16.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
