Technical Field

[0001] The utility model belongs to the technical field of capping machines, in particular to a pneumatic capping machine. Background Art

[0002] A pneumatic capping machine is a mechanical device that uses compressed air or steam as a power source. It is mainly used to press the bottle cap onto the bottle mouth. Its working principle is to achieve the capping action through common mechanisms such as pneumatic components, connecting rods, and levers. Pneumatic capping machines are usually divided into manual and automatic types. When connecting the bottle cap to the bottle mouth, a capping machine is usually required to press it, so that the connection is more secure and avoid leakage during transportation.

[0003] A Chinese patent with authorization announcement number CN208429840U discloses a pneumatic capping machine, including a frame, a capping cylinder is provided on the top of the frame, the end of the piston rod of the capping cylinder is detachably connected to a pressure plate, a lifting platform is provided under the pressure plate, and an adjustment mechanism for adjusting the lifting of the lifting platform is provided at the bottom of the lifting platform, and an adjustable positioning mechanism for positioning paint packaging barrels is provided on the lifting platform; the utility model has a simple structure, low cost, and is easy to use. It can cap paint packaging barrels of different heights and can accurately position paint packaging barrels of different barrel diameters. It is easy to adjust and has strong versatility.

[0004] However, the above solution still has some problems. If a larger platform is directly set up to place the bottle body, the subsequent cleaning intensity of the capping machine will increase, so it is necessary to adjust the size of the placement platform according to the size of the bottle body, thereby expanding the scope of application of the capping machine. Therefore, a pneumatic capping machine is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and address the problems existing in the existing equipment, the utility model proposes a pneumatic capping machine.

[0006] The cam is fixedly provided with a support rod, and one end of the support rod is fixedly connected to the placement platform, and a plurality of connecting grooves are provided on the placement platform, and a plurality of connecting grooves are symmetrically provided with a card slot inside the plurality of connecting grooves.

The bottom of the placement platform is hinged with a plurality of sets of hinged rods, and the hinged rod is located at the outside of the connecting groove, and an extension plate is hinged on the hinged rod, and a card block is fixedly connected to the extension plate, and the card block is movably connected to the card slot. One side of the extension plate is movably connected to the connecting slot, and the bottom of the base is fixedly connected with an anti-slip pad, and a limit rod is symmetrically provided on the upper surface of the base. The anti-slip pad can increase the friction between the desktop or the ground, thereby making the pneumatic capping machine more stable during operation.

[0007] Preferably, the limiting rod is symmetrically provided with a sliding groove, the base is rotatably connected to a threaded rod, and the threaded rod is located between the two groups of limiting rods, and the limiting rod is slidably connected to a support block, and the support block can be driven to move up and down by rotating the threaded rod.

[0008] Preferably, a threaded hole is opened in the middle of the support block, the threaded hole is threadedly connected to the threaded rod, one end of the limit rod is fixedly connected to the top plate, and the base cooperates with the top plate to support the threaded rod, thereby ensuring the stability of the threaded rod when rotating.

[0009] Preferably, one end of the threaded rod is rotatably connected to the inside of the top plate, and one end of the threaded rod is fixedly connected to a turning handle, which extends to the outside of the top plate. By rotating the turning handle, the threaded rod can be driven to rotate, thereby adjusting the height of the support block.

[0010] Preferably, the upper surface of the support block is fixedly connected to a connecting plate, the upper surface of the connecting plate is fixedly connected to a cylinder, the output end of the cylinder is fixedly connected to a capping head, the capping head is located below the connecting plate, an air inlet is provided on the cylinder, and a foot switch is provided on the cylinder. The cylinder is controlled by the foot switch, thereby driving the capping head to move, and the bottle body can be capped.

[0011] Preferably, a feeding hole is provided on the connecting plate, a rotating ball is rotatably connected to the inside of the connecting plate, the rotating ball is slidably connected to the inside of the slide groove, oil storage cotton is provided inside the connecting plate, a filter is provided outside the oil storage cotton, the filter is fixedly connected to the inside of the connecting plate, the filter is located between the oil storage cotton and the rotating ball, which can prevent the oil storage cotton from being damaged when the rotating ball rotates too fast.

[0012] The benefit of the present invention is that the pneumatic capping machine not only needs to cap bottles of the same size, but the placement platform can also support bottles with smaller bottoms. The extension plates around the placement platform are lifted upward, one side of which enters the connecting groove, and the card block enters the card groove. When the four groups of extension plates are in a horizontal state, they cooperate with the placement platform to form a larger platform to support bottles with larger bottoms, so that the capping machine is suitable for bottles of different sizes, thereby expanding the scope of application of the pneumatic capping machine.

[0013] When the utility model adjusts the height of the cylinder, it is necessary to move the connecting plate to adjust the height. When the connecting plate moves, the rotating ball inside it rotates by friction in the slide groove. When the rotating ball rotates, its surface passes through the filter screen, squeezing the filter screen and the oil storage cotton, so that the surface of the rotating ball is attached with lubricating oil, making the connecting plate move more smoothly, thereby avoiding the phenomenon of jamming when the capping machine is used, and extending the service life of the capping machine.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 As shown, a pneumatic capping machine includes: a base 1, the upper surface of the base 1 is fixedly connected to a support rod 2, one end of the support rod 2 is fixedly connected to a placement platform 3, a plurality of groups of connecting grooves 4 are provided on the placement platform 3, the multiple groups of connecting grooves 4 are symmetrically provided with card slots 5, a spring 6 is fixedly connected to the inside of the card slot 5, one end of the spring 6 is fixedly connected to a rubber pad 7, the rubber pad 7 is fixedly connected to the card slot 5, the bottom of the placement platform 3 is hinged to a plurality of groups of hinged rods 8, the hinged rods 8 are located on the outside of the connecting groove 4, an extension plate 9 is hinged on the hinged rod 8, a card block 10 is fixedly connected to the extension plate 9, the card block 10 is movably connected to the card slot 5, and one side of the extension plate 9 is connected to the card slot 5. The connecting groove 4 is movably connected, and the bottom of the base 1 is fixedly connected to a non-slip pad 11. A limit rod 12 is symmetrically provided on the upper surface of the base 1, and a slide groove 13 is symmetrically opened on the limit rod 12. The base 1 is rotatably connected to a threaded rod 14, and the threaded rod 14 is located between the two groups of limit rods 12. A support block 15 is slidably connected to the limit rod 12, and a threaded hole 16 is opened in the middle of the support block 15. The threaded hole 16 is threadedly connected to the threaded rod 14. One end of the limit rod 12 is fixedly connected to a top plate 17, and one end of the threaded rod 14 is rotatably connected to the inside of the top plate 17. One end of the threaded rod 14 is fixedly connected to a turning handle 18, and the turning handle 18 extends to the outside of the top plate 17;

[0023] When the bottle body and the bottle cap are capped, a pneumatic capping machine is required to improve the efficiency of capping. In actual use, when the bottle body is large, the extension plates 9 around the placement platform 3 are lifted upward, so that the extension plates 9 rotate with the hinge rod 8 as the axis. During the rotation, one side of the extension plate 9 enters the interior of the connecting groove 4. During the rotation, the clamping blocks 10 on both sides push the connecting groove 4 outward, so that the clamping block 10 can enter the interior of the clamping groove 5. The clamping block 10 is in contact with the rubber pad 7. At the same time, the spring 6 can push the rubber pad 7 toward the clamping block 10, increasing the friction with the surface of the clamping block 10, thereby improving the stability of the extension plate 9 when it is in a horizontal state. When the extension plates 9 on all four sides are lifted upward, a larger platform is formed on the outside of the placement platform 3, so that larger bottles can be placed.

[0024] Before placing the bottle body, the height of the capping head 21 is adjusted according to the height of the bottle body, and the handle 18 is rotated to drive the threaded rod 14 to rotate, thereby driving the support block 15 and the connecting plate 19 to move through the threaded hole 16 that fits the threaded shape on its surface, and the height of the capping head 21 can be adjusted so that the distance between the capping head 21 and the placement platform 3 is sufficient to place the bottle body. When the support block 15 moves, the two sets of limit rods 12 can prevent the support block 15 from rotating when moving. The top plate 17 and the base 1 cooperate to limit the moving range of the support block 15 to prevent the support block 15 from falling off. At the same time, the anti-slip pad 11 can increase the friction between the desktop or the ground, thereby making the pneumatic capping machine more stable during operation.

[0025] See also Figure 1-5 As shown, the upper surface of the support block 15 is fixedly connected to a connecting plate 19, the upper surface of the connecting plate 19 is fixedly connected to a cylinder 20, the output end of the cylinder 20 is fixedly connected to a capping head 21, the capping head 21 is located below the connecting plate 19, an air inlet is provided on the cylinder 20, a foot switch 22 is provided on the cylinder 20, a feeding hole 23 is provided on the connecting plate 19, the interior of the connecting plate 19 is rotatably connected to a rotating ball 24, the rotating ball 24 is slidably connected to the interior of the chute 13, the interior of the connecting plate 19 is provided with an oil storage cotton 25, the outside of the oil storage cotton 25 is provided with a filter screen 26, and the filter screen 26 is fixedly connected to the interior of the connecting plate 19;

[0026] After the bottle body and bottle cap are placed, the cylinder 20 is controlled by the foot switch 22 to drive the capping head 21 to move downward, thereby capping the bottle body. When the threaded rod 14 drives the connecting plate 19 to move through the support block 15, the rotating ball 24 inside the connecting plate 19 rubs against the slide groove 13 and rotates. When the rotating ball 24 rotates, its surface passes through the filter screen 26, squeezing the filter screen 26 and the oil storage cotton 25, so that the surface is covered with lubricating oil, and then the connecting plate 19 moves more smoothly, avoiding the phenomenon of jamming when the capping machine is used, and extending the service life of the capping machine. If the lubricating oil in the oil storage cotton 25 is insufficient, the oil storage cotton 25 can be added through the feeding hole 23, and the oil storage cotton 25 can be pressed through the feeding hole 23 to detect whether the oil storage cotton 25 contains lubricating oil.

[0027] Working principle: the height of the capping head 21 is adjusted according to the height of the bottle body, the handle 18 is rotated, and the threaded rod 14 is driven to rotate, thereby driving the support block 15 and the connecting plate 19 to move through the threaded hole 16 that fits the threaded shape on its surface, and the height of the capping head 21 can be adjusted so that the distance between the capping head 21 and the placement platform 3 is sufficient to place the bottle body, and the extension plate 9 around the placement platform 3 is lifted upward so that the extension plate 9 is rotated with the hinge rod 8 as the axis. During the rotation, one side of the extension plate 9 enters the interior of the connecting groove 4, and the block 10 can enter the interior of the card slot 5, thereby fixing the extension plates 9 on all four sides, forming a larger platform on the outside of the placement platform 3, placing the bottle body on the placement platform 3, and controlling the cylinder 20 through the foot switch 22 to drive the capping head 21 to move downward, thereby capping the bottle body.
