[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 6 As shown, the sealing clamp adjustment device of the large infusion bottle combination cover according to the embodiment of the present invention comprises a clamp housing 1, a limiting block 2 is fixed at the top of the clamp housing 1, a first motor 21 is installed inside the limiting block 2, a turntable 22 is arranged below the first motor 21, the turntable 22 is rotatably connected to the inside of the limiting block 2, a plurality of clamping rollers 4 are arranged at equal intervals below the limiting block 2, a moving frame 43 is arranged on one side of the clamping roller 4, a sliding column 431 is fixed at the top of the moving frame 43, and the bottom end of the turntable 22 is opened. A displacement groove 223 is provided, a sliding column 431 is slidably connected inside the displacement groove 223, a guide groove 23 is opened at the bottom end of the limit block 2, a moving frame 43 is slidably connected inside the guide groove 23, a guide shell 42 is fixed to the bottom end of the moving frame 43, the outside of the clamping roller 4 is rotatably connected to the support frame 41, a second telescopic column 411 is fixed on one side of the support frame 41 close to the guide shell 42, the second telescopic column 411 is slidably connected inside the guide shell 42, and an edge banding wheel 447 is provided below the clamping roller 4;

[0032] After filling the interior of the large infusion bottle, it is necessary to seal the bottle mouth of the large infusion bottle with a combined cover. At this time, a sealing clamp will be used to put the combined cover on the outside of the bottle mouth. The sealing clamp is one of the components of the sealing equipment. Before sealing, the position of the clamping roller 4 is adjusted according to the specifications of the bottle mouth. During adjustment, the second telescopic column 411 will extend and retract inside the guide shell 42. During the extension and retraction process, the second telescopic column 411 will drive the support frame 41 to move, and the movement of the support frame 41 drives the clamping roller 4 to move. At this time, the distance between the multiple clamping rollers 4 is adjusted, and the inner diameter of the clamp can be adjusted without replacing the clamp. Then, the sealing is performed. Before sealing, the combined cover is placed on the bottle mouth of the large infusion bottle, and then the large infusion bottle is placed on the processing position of the sealing equipment. During the sealing process, the sealing equipment lowers the clamp shell 1 so that the clamp shell 1 is put on the outside of the bottle mouth. At this time, the clamping roller 4 is placed on the outside of the combined cover on the bottle mouth, and then the turntable 22 rotates to drive the displacement groove 223 The movable frame 43 is moved toward the center direction of the limit block 2 in the guide groove 23 due to the limit guide of the guide groove 23. At this time, the movable frame 43 drives the support frame 41 to move through the guide shell 42, and the support frame 41 drives the clamping roller 4 to be close to the outer side of the combined cover. At the same time, the edge-sealing wheel 447 squeezes the edge of the bottom of the combined cover. Then the sealing device drives the clamp shell 1 to rotate. At this time, the clamp shell 1 drives the clamping roller 4 and the edge-sealing wheel 447 to rotate at the same time. The clamping roller 4 compacts the outer side of the combined cover, and the edge-sealing wheel 447 seals the bottom of the combined cover. At this time, the combined cover can be sealed to the bottle mouth of the large infusion bottle. After sealing, the turntable 22 rotates in the opposite direction to make the clamping roller 4 away from the bottle mouth. Then the sealing device lifts the clamp shell 1. At this time, the clamp shell 1 is separated from the large infusion bottle and the sealing is completed. Repeat this operation to seal other large infusion bottles.

[0033] like Figure 1 to Figure 2 As shown, an inner gear ring 221 is fixed to the top of the turntable 22, and a first output gear 211 is fixed to the end of the rotating shaft of the first motor 21. The first output gear 211 is located in the middle of the top of the turntable 22, and a plurality of planetary gears 222 are meshed and connected between the outer side of the first output gear 211 and the inner side of the inner gear ring 221 at equal intervals.

[0034] When adjusting the position of the clamping roller 4, the turntable 22 needs to rotate. At this time, the first motor 21 is started to drive the first output gear 211 to rotate. At this time, the first output gear 211 drives the planetary gear 222 to rotate. When the planetary gear 222 rotates, it will also drive the inner ring gear 221 to rotate. The inner ring gear 221 drives the turntable 22 to rotate. The forward and reverse rotation of the first motor 21 can control the moving direction of the clamping roller 4 driven by the turntable 22.

[0035] like Figures 1 to 6As shown, a transmission gear 33 is provided on one side of the guide housing 42, a stud 421 is rotatably connected inside the guide housing 42, a threaded hole matching the stud 421 is provided inside the second telescopic column 411, and the outer side of the stud 421 is threadedly connected to the threaded hole of the second telescopic column 411;

[0036] When the position of the clamping roller 4 needs to be adjusted, the transmission gear 33 is rotated to drive the stud 421 to rotate. At this time, the stud 421 can drive the second telescopic column 411 to be telescoped inside the guide shell 42. Through the telescopic adjustment, the support frame 41 can drive the clamping roller 4 to move to different positions, thereby adjusting the sealing specifications of the clamping roller 4.

[0037] like Figures 1 to 6 As shown, a rotating block is fixed to the side of the transmission gear 33 close to the guide housing 42, and the rotating block is rotatably connected to the side wall of the clamp housing 1. A first telescopic column 332 is fixed to the side of the rotating block away from the transmission gear 33. A hole matching the outer diameter of the first telescopic column 332 is opened inside the stud 421, and the first telescopic column 332 is inserted into the hole of the stud 421.

[0038] When the turntable 22 drives the moving frame 43 to move, the moving frame 43 will drive the guide shell 42 to move at the same time, but the position of the transmission gear 33 is fixed. At this time, one side of the transmission gear 33 is movably connected with the stud 421 through the first telescopic column 332. When the guide shell 42 moves, the first telescopic column 332 and the stud 421 can still maintain a connection state, which is more convenient for subsequent adjustments.

[0039] like Figures 1 to 6 As shown, a second motor 31 is installed on one side of the clamp housing 1, an upper gear ring 3 is arranged above the transmission gear 33, a second output gear 311 is fixed to the end of the rotating shaft of the second motor 31, the second output gear 311 is meshed and connected with one side of the upper gear ring 3, a lower gear ring 331 is fixed to the bottom end of the upper gear ring 3, the lower gear ring 331 is meshed and connected with a plurality of transmission gears 33, a plurality of support columns 32 are arranged above and below the upper gear ring 3, and the support columns 32 are fixedly connected to the outer side of the clamp housing 1;

[0040] When the transmission gear 33 needs to be rotated for adjustment, multiple transmission gears 33 need to be rotated. At this time, the second motor 31 is started to drive the second output gear 311 to rotate. During the rotation of the second output gear 311, the upper ring gear 3 will be driven to rotate. At this time, the upper ring gear 3 will drive the multiple transmission gears 33 below it to rotate at the same time. At this time, multiple clamping rollers 4 can complete the adjustment synchronously, saving adjustment time and reducing errors caused by individual adjustments.

[0041] like Figures 6 to 8As shown, a lower rotating block 441 is fixed to the bottom end of the clamping roller 4, a fixed block 444 is fixed to the outside of the lower rotating block 441, an extension arm 446 is rotatably connected to the bottom end of the fixed block 444, and a side of the top end of the extension arm 446 away from the fixed block 444 is rotatably connected to the edge banding wheel 447;

[0042] During the sealing process of the combination cover, it is necessary to seal the edge of the bottom of the combination cover. Therefore, when the clamping roller 4 contacts the combination cover, the extension arm 446 drives the edge sealing wheel 447 to expand. At this time, the edge sealing wheel 447 will squeeze the bottom edge of the combination cover to deform it. During the rotation of the clamp shell 1, the clamping roller 4 drives the edge sealing wheel 447 to rotate. During the rotation of the edge sealing wheel 447, the bottom edge of the combination cover can continue to be deformed. At this time, the edge can be pressed tightly and the fixation can be completed. After use, the extension arm 446 drives the edge sealing wheel 447 to return to its original position. At this time, the edge sealing wheel 447 can be prevented from interfering when the clamp shell 1 is sleeved on the outside of the bottle mouth.

[0043] like Figures 2 to 8 As shown, a torsion spring 445 is fixed between the fixed block 444 and the extension arm 446, a compression chamber 432 is provided at one end of the movable frame 43 near the sliding column 431, a first spring 433 is fixed at the side of the compression chamber 432 away from the clamping roller 4, a push column 434 is inserted at the side of the compression chamber 432 near the clamping roller 4, a piston is fixed at the side of the push column 434 near the first spring 433, the piston is fixedly connected to the first spring 433, and an oil guide channel 435 is provided at the inside of the movable frame 43. One end of the oil guide channel 435 is connected to the compression chamber 432, and one end of the oil guide channel 435 away from the compression chamber 432 is connected to an oil guide hose 436, and the other end of the oil guide hose 436 is rotatably connected to the bottom end of the lower rotating block 441 through a connecting block, and an oil delivery hole 442 is opened inside the lower rotating block 441, and a telescopic rod 443 is slidably connected inside the oil delivery hole 442, and one end of the telescopic rod 443 extends to the outside of the lower rotating block 441, and the telescopic rod 443 is closely attached to the inner side of the extension arm 446;

[0044] The compression chamber 432, the oil guide channel 435, the oil guide hose 436 and the oil delivery hole 442 are filled with oil. When the movable frame 43 moves in the guide groove 23, the push column 434 will be driven to move. When the clamping roller 4 is close to the combination cover, the push column 434 will contact the inner wall of the guide groove 23, and then the push column 434 will be pushed in the movement process. The push column 434 pushes the piston to squeeze the oil in the compression chamber 432. The oil is input into the oil guide hose 436 through the oil guide channel 435, and the oil guide hose 436 is input into the oil delivery hole 442. The oil in the oil delivery hole 442 will push the telescopic rod 443 to extend outward, and push the extension arm 446 in the extension process. The extension arm 446 rotates in the opposite direction. At this time, the extension arm 446 can drive the edge sealing wheel 447 to fully expand when the clamping roller 4 is close to the outer wall of the combined cover. When the sealing is completed, the movable frame 43 moves in the opposite direction inside the guide groove 23. At this time, the push column 434 loses its thrust, and the first spring 433 pushes the push column 434 to restore its original position. At this time, the piston of the push column 434 can extract oil. At the same time, the torsion spring 445 will also drive the extension arm 446 to rotate in the opposite direction. At this time, the extension arm 446 pushes the telescopic rod 443, and the telescopic rod 443 pushes the oil to assist the piston of the push column 434 in extracting oil, thereby realizing automatic expansion and storage of the edge sealing wheel 447 and reducing the interference of the edge sealing wheel 447 with the bottle mouth during the lifting process of the clamp shell 1.

[0045] like Figure 6 to Figure 7 As shown, a rotating shaft 44 is fixed to the top of the clamping roller 4, a rotating hole 412 is opened at the top of the support frame 41, the rotating shaft 44 is rotatably connected to the inside of the rotating hole 412, a pressure sensor 413 is installed on one side of the rotating hole 412, and a rotating wheel is rotatably connected to the side of the pressure sensor 413 close to the rotating shaft 44, and the rotating wheel is close to the side wall of the rotating shaft 44;

[0046] When the clamping roller 4 is close to the outer wall of the combination cover, the clamping roller 4 will be pushed in the opposite direction by the combination cover, and the clamping roller 4 transmits the force to the pressure sensor 413 through the rotating shaft 44. The pressure sensor 413 can detect the pressure. When the pressure value is too high, there is a risk of crushing the bottle mouth by the clamping roller 4. At this time, an alarm will be issued through the sealing device. When the pressure value is too low, the clamping roller 4 fails to press the combination cover tightly. At this time, the sealing device will also issue an alarm and start the second motor 31 to rotate to adjust the tightness between the clamping roller 4 and the combination cover according to the situation.

[0047] like Figures 3 to 9As shown, an adjusting hole 232 is provided at the bottom end of the limit block 2, a plurality of telescopic holes 231 are provided on the outer side of the adjusting hole 232, and one end of the telescopic hole 231 is communicated with the guide groove 23, a top plate 5 is provided below the limit block 2, a third telescopic column 51 is fixed on the top end of the top plate 5, the third telescopic column 51 is slidably connected to the inside of the adjusting hole 232, a plurality of limiting grooves 511 are provided on the outer side of the third telescopic column 51, a telescopic block 53 is slidably connected to the inside of the telescopic hole 231, a tooth plate 531 is fixed to the side of the telescopic block 53 close to the third telescopic column 51, the tooth plate 531 and the limiting groove 511 can form a snap-fit ​​structure, a push rod 532 is fixed to the side of the telescopic block 53 away from the tooth plate 531, one end of the push rod 532 away from the telescopic block 53 extends into the inside of the guide groove 23, and a rotating disk is rotatably connected to the bottom end of the top plate 5;

[0048] The heights of combination covers of different specifications will also be different, so the position of the top plate 5 needs to be adjusted synchronously. When the sealing device pushes the clamp housing 1 down to cover the bottle mouth, the rotating disk at the bottom of the top plate 5 will contact the top of the combination cover. Under the push of the combination cover, the top plate 5 will rise upward. At this time, the top plate 5 pushes the third telescopic column 51 to extend into the inside of the adjustment hole 232. The height of each lifting and lowering of the clamp housing 1 is a fixed height. Therefore, the height of the top plate 5 will be automatically adjusted according to the height of the combination cover. When the clamp housing 1 is lowered to a fixed position, the clamping roller 4 will be close to the surface of the combination cover. At this time, the moving frame 43 moves inside the guide groove 23 during the process. When the clamping roller 4 is completely close to the combined cover, the movable frame 43 will squeeze the part of the push rod 532 extending into the guide groove 23 back into the telescopic hole 231. At this time, the push rod 532 pushes the telescopic block 53 to drive the tooth plate 531 to be inserted into the limiting groove 511 of the current height. At this time, the third telescopic column 51 can be fixed inside the adjusting hole 232. During the sealing process, the top plate 5 is in a fixed state to support the top of the combined cover. There is a rubber pad in the combined cover. During the movement of the push rod 532, the tooth plate 531 and the limiting groove 511 are engaged prematurely and the top plate 5 cannot move. At this time, the deformation of the rubber pad can compensate for the distance that the combined cover continues to move upward.

[0049] like Figures 3 to 9 As shown, the outer sleeve of the third telescopic column 51 is provided with a second spring 52, the bottom end of the second spring 52 is fixedly connected to the top plate 5, the top end of the second spring 52 is fixedly connected to the bottom end of the limit block 2, the upper surface of the teeth of the tooth plate 531 is an inclined surface and the lower surface is a plane, and the internal shape of the limit groove 511 matches the shape of the tooth plate 531;

[0050] When the sealing is completed, the clamping roller 4 is separated from the combined cover, and the movable frame 43 moves and separates from the push rod 532. At this time, the push rod 532 loses its thrust, and then the clamp housing 1 rises. At this time, the top plate 5 also loses its thrust, and the elastic force of the second spring 52 pushes the top plate 5 to move downward. At this time, the third telescopic column 51 moves downward. Due to the shape characteristics of the tooth plate 531 and the limiting groove 511, the tooth plate 531 can be pushed out of the limiting groove 511. At this time, the push rod 532 re-extends into the guide groove 23 and returns to its original position, so that the height of the top plate 5 can be automatically adjusted according to the height of the bottle mouth and the combined cover.
