A first spring 13 is fitted onto the fixed post 12, and the two ends of the first spring 13 are respectively connected to the fixed post 12 and the sleeve 14. In the middle, a shielding tube 7 is installed at one end of the sleeve 14. A filter screen 15 is installed on the side of the shielding tube 7 near the sleeve 14. A hollow cleaning rod 19 is fixedly connected to the inner wall of the shielding tube 7. An air vent 16 is installed at one end of the cleaning rod 19. The air vent 16 is connected to the cleaning rod 19. An air vent 17 is opened on the side of the air vent 16. The air vent 17 is opened at an angle towards the side near the cleaning rod 19. An air pump is installed on the inner wall of the cleaning rod 19. A cleaning sleeve 18 is fixedly fitted on the cleaning rod 19 near the air vent 16. Brush bristles are provided on the cleaning sleeve 18.

[0042] The mounting structure includes a mounting sleeve 8 installed at one end of the second rotating rod 6. A mounting post 11 is movably inserted into the mounting sleeve 8. The mounting post 11 and the mounting sleeve 8 are movably connected to a mounting rod 9. Nuts 10 are tightened at both ends of the mounting rod 9 via threads.

At this time, the fourth motor is started to drive the second rotating rod 6 and the shielding cylinder 7 to rotate as a whole. The processed core cap is inserted into the shielding cylinder 7. The rotating bristles are used to clean the debris inside the core cap. At the same time, the air pump is started, and air is blown towards the inner wall of the core cap through the air outlet 17. Combined with the cleaning of the bristles, the debris inside the core cap can be better cleaned into the shielding cylinder 7 for collection. This makes cleaning the debris inside the core cap more labor-saving and convenient.

A pulley 28 is fixedly sleeved on both the output shaft of the first motor 27 and one of the fourth rotating rods 25. A belt 29 is tightly sleeved between the two pulleys 28.

[0044] The adjustment structure includes a bidirectional screw 30 that rotates through the machining seat 3. Handwheels 31 are installed at both ends of the bidirectional screw 30. The bidirectional screw 30 passes through a threaded groove on the adjustment seat 20. When the core cap moves between the two pusher wheels 22, the first motor 27 on the fixed seat 26 is started. The motor drives one of the fourth rotating rods 25 to rotate through the belt 29 and the pulley 28. Under the action of the two first gears, the two fourth rotating rods 25 are driven to rotate. Thus, under the action of the universal joint 24 and the intermediate rod 23, the two sets of third rotating rods 21 and the pusher wheels 22 are driven to rotate, so that the core cap moves down at a constant speed between the two pusher wheels 22 to perform thread processing. In addition, the bidirectional screw 30 can be rotated by the handwheel 31 according to the actual needs. The bidirectional screw 30 has two sections of threads with opposite thread directions. The two adjustment seats 20 move synchronously in opposite directions to flexibly adjust the distance between the two pusher wheels 22.

Two connecting rods 50 are connected to the movable ring 48. One end of the connecting rod 50 is connected to the first fixed cylinder 36. A second spring 49 is sleeved on the transfer rod 47. The two ends of the second spring 49 are respectively connected to the movable ring 48 and one end of the transfer rod 47. The second motor 33 on the U-shaped plate 32 drives the rotating disk 34 to rotate, thereby driving the material picking cylinder. When the core cap to be processed is obtained in the picking cylinder 39, the first electric push rod 37 is activated to drive the driving block 38 to move. The second gear 45 drives the flip handle 44 and the clamping block 41 to rotate as a whole, thereby clamping and fixing the core cap in the picking cylinder 39. When the core cap rotates to the processing position or the unloading position, the second electric push rod 46 in the second fixed cylinder 78 is activated to drive the picking cylinder 39 to move, so that the core cap can be smoothly transported between the two push wheels 22 for thread processing, and the core cap can be moved to the unloading position for unloading.

[0048] See Figure 1 The collection structure includes a collection cylinder 51 located at the rear of the workbench 1, a sleeve rod 52 on the collection cylinder 51, the sleeve rod 52 being hung on the shielding frame 2, and a receiving plate 53 installed at the upper edge of the collection cylinder 51.

[0049] See Figures 6-9 The rotating storage structure includes an L-shaped rod 54 connected to the middle of the U-shaped plate 32. The top of the L-shaped rod 54 is connected to a feeding cylinder 55. A first feeding port is opened on the side of the feeding cylinder 55. A switching sleeve 57 is rotatably sleeved on the outer side of the feeding cylinder 55. Multiple second feeding ports are opened on the side of the switching sleeve 57. A storage frame 56 is installed at each second feeding port on the side of the switching sleeve 57. A pusher rod 59 is movably inserted into the end of the storage frame 56 away from the feeding cylinder 55. A pull ring 61 is installed at one end of the pusher rod 59. A pusher block 58 is set at one end of the pusher rod 59 inserted into the storage frame 56. A fixing ring 60 is fixedly sleeved on the pusher rod 59. A third spring 62 is sleeved on the pusher rod 59. The two ends of the third spring 62 are respectively connected to the fixing ring 60 and the storage frame 56.

[0050] The positioning structure includes a fixing piece 64 connected to the upper edge of the feed cylinder 55, a positioning pin 63 moving through the fixing piece 64, and a positioning sleeve 65 provided on the side of the switching sleeve 57 between two adjacent storage frames 56, with the bottom end of the positioning pin 63 moving through one of the positioning sleeves 65.

[0051] The ejection structure includes two vertical rods 66 connected to the feed cylinder 55. A top plate 67 is installed at the top of the vertical rods 66, and a third electric push rod 68 is installed on the top plate 67. A pusher column 69 is set at the bottom of the output shaft of the third electric push rod 68. The bottom end of the pusher column 69 is movably inserted into the feed cylinder 55. A lifting ring 70 is closely attached to the discharge port at the bottom of the feed cylinder 55. Two baffle blocks 73 are movably inserted into the lifting ring 70. Multiple guide rods 71 ​​are connected to the bottom of the feed cylinder 55. The lifting ring 70 is movably sleeved on the guide rods 71. A fourth spring 72 is sleeved on the guide rods 71. The fourth spring 72 is connected at both ends to the lifting ring 70 and the bottom of the guide rod 71, respectively. Two stop blocks 73 are separated by a side strip 74 on one side, with one end of the side strip 74 fixedly passing through the through rod 75. Two fixing plates 76 are connected to the lower edge of the feed cylinder 55. A drive groove 77 is provided on the fixing plate 76, through which the through rod 75 moves. When storing the core cap, the pusher block 58 can be pulled open on the storage frame 56 using the pull ring 61. A feed groove is provided on the top of the storage frame 56, and the core caps to be processed are sequentially stored in the storage frame 56 from the feed groove. In step 6, after storage, the pull ring 61 is released, and the elastic force of the third spring 62 is used to pull the pusher block 58 to press against the stored core cap in the storage frame 56. Then, the bottom end of the positioning pin 63 is pulled out from the positioning sleeve 65, releasing the positioning of the switching sleeve 57 on the feed cylinder 55. Then, the switching sleeve 57 is rotated on the feed cylinder 55 to switch one of the storage frames 56 containing the core cap to the first feed port on the feed cylinder 55. The storage frame 56 is connected to the feed cylinder 55 through the corresponding second feed port. In this way, under the action of the elastic force of the third spring 62, the pusher block 58 is pushed against the core cap in the storage frame 56. When the core cap in the storage box 56 moves into the feeding cylinder 55, and the corresponding picking cylinder 39 switches to the position below the feeding cylinder 55, the third electric push rod 68 is activated to drive the push column 69 to move down. The push column 69 pushes the core cap in the feeding cylinder 55 to move down, thereby squeezing and pushing the lifting ring 70 to move up and down on the guide rod 71, and then driving the through rod 75 to slide down in the driving groove 77. As the lifting ring 70 moves down, it automatically pulls the baffle blocks 73 open to both sides. In this way, the core cap in the feeding cylinder 55 can be automatically fed into the picking cylinder 39, realizing the automatic feeding function.

[0052] The implementation principle of a valve core cap thread processing device according to an embodiment of the present invention is as follows: First, the pusher block 58 is pulled open on the storage frame 56 using the pull ring 61. A feed groove is provided on the storage frame 56. The core caps to be processed are sequentially stored in the storage frame 56 from the feed groove. After storage, the pull ring 61 is released, and the pusher block 58 is pulled to press the stored core caps against the storage frame 56 using the elastic force of the third spring 62. Then, the bottom end of the positioning pin 63 is pulled out from the positioning sleeve 65, and the positioning of the switching sleeve 57 on the feed cylinder 55 is released. Then, the switching sleeve 57 is rotated on the feed cylinder 55 to switch one of the storage frames 56 containing the core caps to the first feed port on the feed cylinder 55. The storage frame 56 and the feed cylinder 55 are connected through the corresponding second feed port. Under the elastic force of the third spring 62, the core cap in the storage frame 56 is pushed to move into the feeding cylinder 55. When the corresponding picking cylinder 39 switches to the position below the feeding cylinder 55, the third electric push rod 68 is activated to drive the push column 69 to move down. The push column 69 pushes the core cap in the feeding cylinder 55 down, thereby squeezing and pushing the lifting ring 70 to move up and down on the guide rod 71, and then driving the through rod 75 to slide down in the driving groove 77. As the lifting ring 70 moves down, it automatically pulls the baffle blocks 73 open to both sides, so that the core cap in the feeding cylinder 55 can be automatically fed into the picking cylinder 39. The second motor 33 on the U-shaped plate 32 is activated to drive the rotating disk 34 to rotate. At the same time as the rotation, the first electric push rod 37 is activated to drive the driving block 38 to move. Gear 45 drives the rotating handle 44 and clamping block 41 to rotate as a whole, thereby clamping and fixing the core cap inside the material taking cylinder 39. When the core cap is transferred to the position directly above the two pusher wheels 22, the second electric push rod 46 is activated to move the clamped core cap between the two pusher wheels 22. At this time, the first motor 27 on the fixed base 26 is activated, which drives one of the fourth rotating rods 25 to rotate through the belt 29 and pulley 28. Under the action of the two first gears, the two fourth rotating rods 25 are driven to rotate. Thus, under the action of the universal joint 24 and the intermediate rod 23, the two sets of third rotating rods 21 and pusher wheels 22 are driven to rotate, so that the core cap moves down at a constant speed between the two pusher wheels 22, and pulls the moving ring 48 to move on the transfer rod 47. When the core cap is fitted onto the... When the processing head 5 is in operation, the third motor is activated to drive the processing head 5 to rotate. This allows the processing head 5 to perform thread processing on the uniformly fed core cap. After processing, the first motor 27 drives the fourth rotating rod 25 to rotate in the opposite direction, thereby moving the processed core cap upwards and resetting it. Simultaneously, the second electric push rod 46 is activated to move the core cap in the opposite direction and reset it. Then, the rotating disk 34 continues to drive the core cap to rotate. When the core cap is moved to the cleaning position, the second electric push rod 46 moves the core cap into the shielding cylinder 7. Rotating bristles clean the debris inside the core cap, and the air pump is activated, blowing air from the air outlet 17 towards the inner wall of the core cap. Combined with the brush cleaning, this better removes debris from the core cap and collects it in the shielding cylinder 7, making the cleaning of debris inside the core cap more labor-saving and convenient.Furthermore, the shielding cylinder 7 can also shield the debris after cleaning, thereby improving the quality of the working environment. Finally, the cleaned core cap is reset, and the rotating disk 34 moves the cleaned core cap to the unloading position. The second electric push rod 46 is activated to move the core cap above the receiving plate 53. The core cap is released in the picking cylinder 39 and falls onto the receiving plate 53, from which it is unloaded into the collecting cylinder 51 for collection. This completes the thread processing of the core cap, which is simple, convenient, and has higher work efficiency.
