[0039] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0040] Reference Figure 1 As shown, the screw cap structure according to the first embodiment of the present invention includes a bearing seat 100, a rotating member 200, a first magnetic ring 300, and a mounting seat 400. The bearing seat 100 has a mounting cavity 110. The rotating member 200 is rotatably disposed in the mounting cavity 110 via a bearing, and a clamp 210 is mounted on the bottom of the rotating member 200. The first magnetic ring 300 is mounted on the bearing seat 100 and sleeved on the rotating member 200. The mounting seat 400 is located below the first magnetic ring 300, and the mounting seat 400 is sleeved on the rotating member 200 and threadedly connected to the rotating member 200. A second magnetic ring 410 is mounted on the upper end of the mounting seat 400, and the second magnetic ring 410 and the first magnetic ring 300 attract each other.

[0041] The first magnetic ring 300 is fixed on the bearing seat 100. The mounting seat 400, on which the second magnetic ring 410 is installed, is threadedly connected to the rotating part 200. When the torque needs to be adjusted, simply rotate the mounting seat 400 to move it up or down, thereby adjusting the distance between the first magnetic ring 300 and the second magnetic ring 410, thus realizing the torque adjustment of the screw cap structure.

[0042] It should be noted that the first magnetic ring 300 and the second magnetic ring 410 attract each other. The force between them is greater when the first magnetic ring 300 is closer to the second magnetic ring 410, and smaller when they are further apart. Because they attract each other, when the bearing seat 100 is driven to rotate, the bearing seat 100 can drive the second magnetic ring 410 to rotate through the first magnetic ring 300. The second magnetic ring 410 can drive the rotating component 200 to rotate, and the rotating component 200 can drive the clamp 210 to rotate. Thus, the clamp 210 can screw the part to be screwed onto the cover. When the torque of the clamp 210 in screwing the part to be screwed onto the cover is greater than the force, the clamp 210 will slip, and the clamp 210 can rotate relative to the bearing seat 100. The second magnetic ring 410 can also rotate relative to the first magnetic force 300. As can be seen from the above, adjusting the distance between the first magnetic ring 300 and the second magnetic ring 410 is equivalent to adjusting the torque of the clamp 210. In some embodiments of this utility model, such as Figure 1 As shown, the bottom of the bearing housing 100 has a receiving cavity 120. The first magnetic ring 300, at least a part of the mounting base 400, and the second magnetic ring 410 are all located in the receiving cavity 120. By providing the receiving cavity 120, larger objects are prevented from entering the space enclosed by the first magnetic ring 300 and the second magnetic ring 410, thus affecting the torque adjustment effect.

[0043] In some embodiments of this utility model, such as Figure 1 As shown, the bearing housing 100 has a first air inlet 111 at its top, which communicates with the mounting cavity 110. The rotating member 200 has a first gas channel 220 inside, and the top of the rotating member 200 has a second air inlet 221 that communicates with the first gas channel 220. The second air inlet 221 communicates with the mounting cavity 110 located above the rotating member 200. The clamp 210 has a second gas channel 211 that communicates with the first gas channel 220. The clamp 210 has a suction port 212 for clamping the workpiece, which communicates with the second gas channel 211.

[0044] By providing a first air inlet 111, a mounting cavity 110, a second air inlet 221, a first gas channel 220, a second gas channel 211, and a suction port 212, the bearing housing 100 can be connected to an external vacuuming device, and the part to be screwed in can be suctioned onto the clamp 210 through the suction port 212.

[0045] During operation, the first air inlet 111 is connected to the air pipe of the external vacuum equipment, the bottom of the clamp 210 abuts against the screw-in part, the vacuum equipment is started, and the gas is discharged through the second gas channel 211, the first gas channel 220, the second air inlet 221, the mounting cavity 110 located above the rotating part 200 and the first air inlet 111, and then the screw-in part is sucked tightly to the bottom of the clamp 210.

[0046] Specifically, the bottom of the clamp 210 may be provided with a locking part to prevent the workpiece to be screwed in from rotating.

[0047] In a further embodiment of this utility model, such as Figure 1 As shown, a first sealing ring 230 is provided between the rotating component 200 and the inner wall of the mounting cavity 110. The first sealing ring 230 is located below the second air inlet 221 to ensure the sealing between the rotating component 200 and the inner wall of the mounting cavity 110.

[0048] In a further embodiment of this utility model, such as Figure 1 As shown, the clamp 210 is installed in the first gas channel 220 in a way that allows it to move up and down. A first elastic element 240 is connected between the top of the clamp 210 and the rotating member 200. By providing the first elastic element 240, the clamp 210 is prevented from crushing the part to be screwed in.

[0049] In a further embodiment of this utility model, such as Figure 1 As shown, a second sealing ring 250 is provided between the outer wall of the clamp 210 and the inner wall of the first gas channel 220 to ensure the sealing between the clamp 210 and the rotating part 200.

[0050] The capping structure 501 according to the second embodiment of the present invention includes a capping machine, and includes the capping structure 501 of the first aspect embodiment, such as... Figure 2 , 3 As shown, it also includes a first mounting plate 500, a second mounting plate 600, a first guide member 700, and a second guide member 800. The rotatable first mounting plate 500 is equipped with multiple capping structures 501 that can move up and down and rotate. These capping structures 501 are spaced apart along the circumference of the first mounting plate 500. The second mounting plate 600 is located below the capping structures 501 and rotates synchronously with the first mounting plate 500. The second mounting plate 600 has multiple placement cavities 610 that correspond one-to-one with the positions of the multiple capping structures 501. The sidewalls of the placement cavities 610 have protrusions 611 to prevent the caps from rotating. The first guide member 700 is located inside the first mounting plate 500, such as... Figure 3 , 4 As shown, the outer circumferential wall of the first guide member 700 is provided with a cam groove 710. The cam groove 710 includes a lifting section 711 and a first lowering section 712 located between the two ends of the lifting section 711. The lifting section 711 is higher than the first lowering section 712. Figure 8 , 9As shown, the second guide member 800 is annular and is installed outside the first guide member 700. The inner wall of the second guide member 800 has internal teeth 810. A connecting block 4000 has one end slidably connected to the cam groove 710. A connecting sleeve 5000 is rotatably mounted on the first mounting plate 500 and is connected to a gear 5001, which is located inside the second guide member 800 and meshes with the internal teeth 810. A connecting rod 6000 is located inside the connecting sleeve 600 and the gear 5001 and is slidably connected to the connecting sleeve 600. The upper end of the connecting rod 6000 is connected to the connecting block 4000. The other end is rotatably connected, and the lower end of the connecting rod 6000 is connected to the capping structure 501; when the connecting block 4000 is in the lifting section 711, the lower end of the clamp 210 is away from the placement cavity 610; when the connecting block 4000 moves from the lifting section 711 to the first lowering section 712, the connecting block 4000 can drive the connecting rod 6000 to move downward relative to the connecting sleeve 600, and the second guide member 800 can drive the connecting rod 6000 to rotate relative to the first mounting plate 500 and the connecting block 4000, so that the connecting rod 6000 can drive the clamp 210 to screw the part to be screwed in on the clamp 210 onto the cap located on the placement cavity 610.

[0051] The second mounting plate 600 is provided with multiple placement cavities 610, each placement cavity 610 corresponding to a capping structure 501. The capping structure 501 can be slidably connected to the cam groove 710 on the outer circumferential wall of the first guide member 700. The second guide member 800 can drive the capping structure 501 to rotate, so that when the first mounting plate 500 rotates, the multiple capping structures 501 on the first mounting plate 500 can move up and down and rotate along the cam groove 710, so that multiple parts to be screwed in can be screwed onto multiple caps in sequence, thereby improving the working efficiency of the capping machine.

[0052] like Figure 3 As shown, taking a capping mechanism 501 as an example, during operation, the first mounting plate 500 and the second mounting plate 600 rotate synchronously. Since the connecting block 4000 is installed on the first mounting plate 500 through the connecting rod 6000 and the connecting sleeve 5000, the connecting block 4000 slides along the cam groove 710 under the rotation of the first mounting plate 500. When the connecting block 4000 rotates along a part of the lifting section 711, the lifting section 711 makes the capping structure 501 located above the placement cavity 610. During the rotation, multiple caps can be sequentially transported to multiple placement cavities 610 by machine or manual operation.

[0053] After the cover is placed in the placement chamber 610 or during the placement of the cover, the part to be screwed in can be conveyed to the clamp 210 by machine or by hand. The external vacuum equipment is activated and the clamp 210 holds the part to be screwed in.

[0054] When the connecting block 4000 moves from the lifting section 711 to the first lowering section 712, the connecting block 4000 drives the connecting rod 6000 to move downward relative to the connecting sleeve 5000. During the rotation of the first mounting plate 500, the gear 5001 on the connecting sleeve 5000 also rotates circumferentially along the first mounting plate 500, causing the gear 5001 to roll along the internal teeth 810 of the second guide member 800. The rotating gear 5001 drives the connecting sleeve 5000 to rotate relative to the first mounting plate 500, thereby causing the connecting sleeve 5000 to drive the connecting rod 6000 to rotate relative to the connecting block 4000. The connecting rod 6000 then drives the capping structure 501 to rotate, so that the clamp 210 can both move downward and rotate, allowing the clamp 210 to screw the part to be screwed onto the cap under the drive of the connecting rod 6000.

[0055] After the screw-in is complete, the vacuum equipment is turned off, the clamp 210 stops holding the part to be screwed in, and the connecting block 4000 also moves to another part of the lifting section 711, causing the clamp 210 to move upward and completely detach from the part to be screwed in. Since the capping structure 501 enters the lifting section 711 again, there is a certain distance between the capping structure 501 and the placement cavity 610. The cap with the screw-in part installed can be taken out from the placement cavity 610. Therefore, when the capping structure 501 enters another part of the lifting section 711, the cap with the screw-in part installed can be taken out by the machine. Then, when the capping structure 501 rotates to another part of the lifting section 711, the cap can be placed back on the placement cavity 610, realizing the cycle work.

[0056] During the rotation of the first mounting plate 500, the connecting rod 6000 also rotates continuously.

[0057] Specifically, the first mounting plate 500 is also ring-shaped; the connecting rod 6000 and the connecting sleeve 5000 are connected by a key, so that the connecting rod 6000 can move up and down relative to the connecting sleeve 5000, and the connecting sleeve 5000 can drive the connecting rod 6000 to rotate.

[0058] In a further embodiment of this utility model, such as Figure 2 As shown, it also includes a frame 7000 and a rotating shaft 8000. The rotating shaft 8000 is rotatably mounted on the frame 7000. The first mounting plate 500 and the second mounting plate 600 are both provided on the rotating shaft 8000 and located on the top of the frame 7000. The first guide 700 and the second guide 800 are both mounted on the top of the frame 7000 so that the capping machine can be easily combined with other structures.

[0059] Specifically, a motor is installed on the frame 7000, and the motor drives the rotating shaft 8000 to rotate through a gear set.

[0060] In a further embodiment of this utility model, such as Figure 3 As shown, one end of the connecting block 4000 is connected to a pulley 4001. The pulley 4001 is located in the cam groove 710 and is slidably connected to the cam groove 710, making the movement of the connecting block 4000 smoother.

[0061] In a further embodiment of this utility model, such as Figure 3 As shown, it also includes a guide rod 4002, which is movably mounted on the first mounting plate 500. The upper end of the guide rod 4002 is fixedly connected to the bottom of the connecting block 4000, so that the guide rod 4002 guides the connecting rod 6000 to move up and down, making the movement of the connecting rod 6000 smoother.

[0062] In a further embodiment of this utility model, such as Figure 2 , 5 As shown, one side of the second mounting plate 600 has a first conveying device 900 for conveying the cover to the placement cavity 610, and the other side of the second mounting plate 600 has a second conveying device 1000. A support plate 620 for placing the part to be screwed in is mounted on the top of the second mounting plate 600. The position of the support plate 620 corresponds to the position of the second conveying device 1000, so that the second conveying device 1000 can convey the part to be screwed in onto the support plate 620.

[0063] like Figure 4 As shown, the cam groove 710 also includes a second lower section 713, one end of which is connected to one end of the lifting section 711, and both ends of the first lower section 712 are respectively connected to the other ends of the second lower section 713 and the other ends of the lifting section 711. The lifting section 711 is higher than the second lower section 713, and the second lower section 713 is higher than the first lower section 712.

[0064] like Figure 3 As shown, when the connecting block 4000 is in the second downward segment 713, the clamp 210 can clamp the part to be screwed in on the support plate 620.

[0065] By incorporating a first conveying device 900, a second conveying device 1000, and a second downward section 713, the automatic feeding of the cap and the parts to be screwed in is achieved, thereby improving the automation of the capping machine.

[0066] like Figure 2 , 3As shown, during operation, the first mounting plate 500 and the second mounting plate 600 rotate counterclockwise synchronously. A portion of the connecting block 4000 on the first mounting plate 500 moves along a portion of the lifting section 711. The lifting section 711 moves the capping structure 501 away from the placement cavity 610. During the rotation, the first conveying device 900 sequentially conveys multiple caps to multiple placement cavities 610. After the caps are placed in the placement cavity 610, the second conveying device 1000 conveys the part to be screwed in to the support plate 620.

[0067] When the connecting block 4000 moves from the lifting section 711 to the second lower section 713, the screw cap structure 501 moves downward under the action of the second lower section 713, so that the clamp 210 abuts against the part to be screwed in on the support plate 620, the external vacuum equipment is started, and the clamp 210 clamps the part to be screwed in.

[0068] When the connecting block 4000 moves from the second lower section 713 to the first lower section 712, the capping structure 501 continues to move downwards. Simultaneously, because the capping structure 501 is driven by the second guide member 800, the clamp 210 can both move downwards and rotate. Thus, the clamp 210 can rotate the part to be screwed onto the cap. After screwing is complete, the vacuum equipment is turned off, the clamp 210 stops holding the part to be screwed onto, and the capping structure 501 rotates to the other lifting section 711, causing the clamp 210 to move upwards. This allows the clamp 210 to completely detach from the part to be screwed in. Since the capping structure 501 enters the lifting section 711 again, there is a certain distance between the capping structure 501 and the placement cavity 610. The cap with the screwed-in part installed can be taken out from the placement cavity 610. Therefore, when the capping structure 501 enters another part of the lifting section 711, the cap with the screwed-in part installed can be taken out by the machine. Then, when the capping structure 501 enters another part of the lifting section 711, the cap can be placed back on the placement cavity 610, realizing cyclical work.

[0069] Specifically, such as Figure 4 As shown, the connection between the lifting segment 711 and the second lowering segment 713 is smooth, the connection between the second lowering segment 713 and the first lowering segment 712 is smooth, and the connection between the first lowering segment 712 and the lifting segment 711 is smooth.

[0070] In a further embodiment of this utility model, such as Figure 2 As shown, it also includes a protrusion 2000 and a collection device 3000 for recycling finished products. The collection device 3000, the first conveying device 900, and the second conveying device 1000 are arranged sequentially at intervals along the circumferential direction (counterclockwise) of the second guide member 800, as shown. Figure 6As shown, each placement cavity 610 has an opening 612 at its bottom, and each placement cavity 610 is provided with a vertically movable push rod 630. The push rod 630 moves between the upper end and the lower end of the placement cavity 610. The outer side of the bottom of the push rod 630 has a boss, and a second elastic member 640 is provided between the boss and the bottom of the second mounting plate 600. Figure 7 As shown, when the upper end of the push rod 630 is at the upper end of the placement cavity 610, the second elastic member 640 is biased and applies a biasing force to move the upper end of the push rod 630 to the lower end of the placement cavity 610.

[0071] like Figure 2 , 7 As shown, the lower end of the push rod 630 has a roller 631, and the protrusion 2000 is used to lift the push rod 630 and move it to the upper end of the placement cavity 610. The protrusion 2000 is arc-shaped and located below the roller 631. The protrusion 2000 extends from the receiving device 3000 to the first conveying device 900.

[0072] By providing a protrusion 2000, when the second mounting plate 600 is rotated to the receiving device 3000, the protrusion 2000 can push out the cover with the screw-in part installed in the placement cavity 610, so that the receiving device 3000 can collect it; and the cover can fall into the placement cavity 610 by its own weight and engage with the protrusion 611.

[0073] Taking a placement cavity 610 as an example, during operation, the second mounting plate 600 rotates counterclockwise. The placement cavity 610 and the push rod 630 on the second mounting plate 600 pass sequentially in a counterclockwise direction through the first conveying device 900, the second conveying device 1000, and the collecting device 3000. When passing the first conveying device 900, the roller 631 on the push rod 630 slides onto the protrusion 2000. The protrusion 2000 drives the push rod 630 to compress the second elastic element 640, causing the push rod 630 to move upward along the placement cavity 610 and move the upper end of the placement cavity 610. The first conveying device 900 conveys the cover onto the push rod 630. The second mounting plate 600 then rotates a certain angle, the roller 631 disengages from the protrusion 2000, and the push rod 630 moves downward under the elastic recovery action of the second elastic element 640. The cover falls into the placement cavity 610 under its own weight. The plate 600 rotates a certain angle, and the second conveying device 1000 conveys the part to be screwed in to the support plate 620. The second mounting plate 600 rotates a certain angle, and the connecting block 4000 rotates from the lifting section 711 to the second lowering section 713. The clamp 210 clamps the part to be screwed in on the support plate 620. The second mounting plate 600 rotates a certain angle, and the capping structure 501 rotates from the second lowering section 713 to the first lowering section 712. The clamp 210 screws the part to be screwed in onto the cap. The second mounting plate 600 rotates a certain angle, and the capping structure 501 rotates from the first lowering section 712 to the lifting section 711. The clamp 210 moves upward and away from the placement cavity 610. The protrusion 2000 pushes up the push rod 630 again. The push rod 630 pushes out the cap with the screwed-in part installed in the placement cavity 610. The collecting device 3000 takes out the cap with the screwed-in part installed.

[0074] Specifically, the collecting device 3000 includes a rotatable scraper disc. When the scraper disc rotates, it scrapes away the covers that have been inserted into the screw-in parts on the second mounting plate 600 in sequence.

[0075] Specifically, both the first conveying device 900 and the second conveying device 1000 may include a feeding channel and a pushing structure, the pushing structure being used to push the material in the feeding channel onto the placement cavity 610 or the support plate 620.
