[0002] In the production of bottled beverages, it is necessary to put the bottle cap on the bottle after the beverage is filled in the bottle. At present, the industry usually uses automatic capping devices for capping, which can save manpower and improve the efficiency of capping. The automatic capping device includes a cap feeding mechanism, a cap pressing mechanism and a control system. Since the cap pressing mechanism cannot control the capping one by one by itself, it is necessary to control the cap feeding speed of the cap feeding mechanism, which affects the production efficiency. Summary of the invention

[0003] In order to realize that the capping mechanism can automatically control the pressing of bottle caps one by one, the present application provides an efficient and stable automatic capping device.

[0004] In the first aspect, the present application provides an efficient and stable automatic lid-lifting device, which adopts the following technical solutions:

[0005] An efficient and stable automatic cover device comprises an automatic cover device body, the automatic cover device body comprises a conveyor belt, side plates are arranged on both sides of the conveyor belt, a pair of columns are fixed on one of the side plates, a cover pressing mechanism is arranged on the column, the cover pressing mechanism comprises a mounting plate mounted on the column, a pair of vertical plates are fixed on one side of the mounting plate, a horizontal plate is fixed on one end of the two vertical plates away from the conveyor belt, a cover pressing cylinder is installed on the horizontal plate, and a lower pressure head is fixed on the end of the piston rod of the cover pressing cylinder;

[0006] A feed baffle is fixed on one side of the two vertical plates, a feed port is arranged on the feed baffle, a conveying slide is fixed on the side of the feed baffle away from the vertical plate, and a vibration plate is connected to the other end of the conveying slide; a blocking component is also arranged on the mounting plate to prevent the bottle cap from falling downward after passing through the feed port and reaching under the lower pressure head.

[0007] By adopting the above technical solution, when the main body of the automatic capping device is working, a number of bottle caps are placed in the vibration plate, and the vibration plate transports the bottle caps to the feed port through the conveying slide, and then passes through the feed port to reach between the two vertical plates, that is, below the lower pressure head, and is blocked from falling by the blocking component. When the conveyor belt conveys the bottle body to the bottom of the lower pressure head, the capping cylinder drives the lower pressure head to move downward, and the lower pressure head pushes the bottle cap downward, so that the bottle cap can be pressed on the bottle mouth of the bottle body to complete the capping operation; wherein, only one bottle cap is allowed to pass through the feed port each time, and after the bottle cap under the lower pressure head completes the capping operation, the next bottle cap can pass through the feed port to reach below the lower pressure head, thereby completing the purpose of pressing the bottle caps one by one.

[0008] Preferably: the blocking assembly includes two rotating shafts respectively arranged on the side of the vertical plate away from the lower pressure head, the two ends of the rotating shafts are respectively rotatably connected to the mounting plate and the feed baffle, a cylinder is fixedly sleeved on the rotating shaft, a discharge baffle is fixed on the cylinder, the lengths of the two discharge baffles extend to below the lower pressure head, and the length of the discharge baffle on the side of the cylinder away from the vertical plate is greater than the length of the discharge baffle on the side of the cylinder close to the vertical plate; when the lower pressure head moves downward, its side surface is always in contact with the discharge baffle.

[0009] By adopting the above technical solution, when the bottle cap passes through the feed port and reaches above the two discharge baffles, the discharge baffles support the bottle cap and prevent it from falling down. When the capping cylinder drives the lower pressure head to push the bottle cap downward, the discharge baffle rotates, so that the bottle cap can move downward. After the bottle cap is covered on the bottle mouth of the bottle body, the capping cylinder drives the lower pressure head to return to its original position. At the same time, the discharge baffle is set on both sides of the cylinder. Due to the longer side, the weight is relatively large. Due to the weight difference of the discharge baffles on both sides of the cylinder, after the lower pressure head is reset, the discharge baffle also rotates upward to its original position, that is, the end close to the vertical plate contacts the vertical plate.

[0010] Preferably, a protrusion is fixed to one end of the discharge baffle close to the vertical plate, and when the capping cylinder is in the original position, the protrusion contacts the feed baffle, and at this time, the discharge baffle is in the horizontal direction.

[0011] By adopting the above technical solution, the function of the convex block can make the discharging baffle return to the horizontal position, so that the bottle cap is placed horizontally under the pressing head, and the bottle cap is pushed downward more smoothly.

[0012] Preferably, one end of the discharge baffle plate close to the vertical plate is configured as an arcuate surface or an inclined surface, and the arcuate surface or the inclined surface is located on a side of the discharge baffle plate close to the lower pressure head.

[0013] By adopting the above technical solution, when the bottle cap moves downward and pushes open the discharging baffle, the bottle cap slides along the curved surface or inclined surface. The curved surface or inclined surface can make the bottle cap move downward more smoothly when pushing open the discharging baffle.

[0014] Preferably, a lifting mechanism for adjusting the capping mechanism up and down is arranged on the column, and at the same time, the height of the vibration plate is adjusted along with the capping mechanism.

[0015] By adopting the above technical solution, the lifting mechanism can adjust the distance between the capping mechanism and the conveyor belt, so as to adapt to bottles of different heights.

[0016] Preferably, the lifting mechanism comprises a top plate whose two ends are fixedly connected to two columns respectively, a lead screw is rotatably connected to the top plate, and the lead screw passes through and is threadedly connected to the mounting plate; the mounting plate passes through the columns.

[0017] By adopting the above technical solution, the lead screw can be moved up and down by rotating the lead screw, thereby driving the mounting plate to move up and down, and the mounting plate drives the capping mechanism to move up and down, thereby adapting to bottles of different heights.

[0018] Preferably, the vibration plate is fixed on an upper sleeve, the upper sleeve is sleeved with a lower sleeve, a plurality of bolt holes are arranged on the lower sleeve, and the upper sleeve and the lower sleeve are fixed with bolts through bolt holes at different heights.

[0019] By adopting the above technical solution, when adjusting the height of the pressure cover mechanism, it is necessary to unscrew the bolts fixing the upper sleeve and the lower sleeve, and then when adjusting the pressure cover mechanism, the upper sleeve slides along the inner wall of the lower sleeve. After adjusting the position of the pressure cover mechanism, the upper sleeve and the lower sleeve can be fixed by bolts through the bolt holes of corresponding heights.

[0020] Preferably, a positioning rod abutting against the column is threadedly connected to the mounting plate.

[0021] By adopting the above technical solution, after rotating the lead screw and adjusting the height of the mounting plate, the positioning rod is twisted toward the column, so that the positioning rod abuts against the column, thereby locking the position of the mounting plate. When the gland structure needs to be adjusted, the positioning rod is twisted away from the column.

[0022] Preferably, a positioning component for locking the position of the bottle body is arranged on the conveyor belt.

[0023] Preferably, the positioning assembly includes a position sensor fixed on the side plate, and the two side plates are fixedly mounted with a positioning cylinder between the two columns, a positioning plate is fixed to the end of the piston rod of the positioning cylinder, and the position sensor is electrically connected to the positioning cylinder.

[0024] By adopting the above technical solution, when the bottle body moves to the position sensor, the position sensor receives an electrical signal and transmits the electrical signal to the positioning cylinder, which drives the positioning plate to move away from the conveyor belt. When the bottle body moves below the lower pressure head, the positioning cylinder drives the positioning plate to move toward the conveyor belt, thereby clamping the bottle body and locking the position of the bottle body below the lower pressure head, so that the capping process can be completed more accurately.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the main body of the automatic capping device is working, a number of bottle caps are placed in the vibration plate, which transports the bottle caps to the feed port through the conveying slide, and then passes through the feed port to reach between the two vertical plates, that is, below the down-pressing head, and is blocked from falling by the blocking component. When the conveyor belt conveys the bottle body to the bottom of the down-pressing head, the capping cylinder drives the down-pressing head to move downward, and the down-pressing head pushes the bottle cap downward, so that the bottle cap can be pressed on the bottle mouth of the bottle body to complete the capping operation; among them, only one bottle cap is allowed to pass through the feed port each time, and the bottle cap under the down-pressing head completes the capping operation before the next bottle cap can pass through the feed port to reach below the down-pressing head, thereby completing the purpose of pressing the bottle caps down one by one.

[0027] 2. By rotating the lead screw, the lead screw can be moved up and down, thereby driving the mounting plate to move up and down, and the mounting plate drives the capping mechanism to move up and down to adapt to bottles of different heights. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present application is further described in detail below in conjunction with the specific contents. Example

[0035] An efficient and stable automatic lidding device, such as Figure 1As shown, the automatic capping device body 1 includes a machine platform 11, on which a conveyor belt 12 for conveying bottles is arranged. Side plates 121 for supporting the conveyor belt 12 are arranged on both sides of the conveyor belt 12, and a pair of columns 2 are fixedly mounted on one of the side plates 121, and a capping mechanism is mounted on the column 2. Figure 2 and Figure 3 As shown, the capping mechanism includes a mounting plate 3 passing through the column 2, and a pair of vertical plates 31 are fixed on the side of the mounting plate 3 close to the conveyor belt 12. A horizontal plate 32 is fixed to the end of the two vertical plates 31 away from the conveyor belt 12. A vertically arranged capping cylinder 321 is installed on the horizontal plate 32, and a lower pressure head 3211 is fixed to the end of the piston rod of the capping cylinder 321. A feed baffle 33 is bolted to the side of the two vertical plates 31 away from the mounting plate 3, and a feed port 331 is arranged on the feed baffle 33. A conveying slide 4 is bolted to the side of the feed baffle 33 away from the mounting plate 3, and the other end of the conveying slide 4 is connected to the vibration plate 41.

[0036] When the main body 1 of the automatic capping device is working, a number of bottle caps are placed in the vibration plate 41, and the vibration plate 41 conveys the bottle caps to the feed port 331 through the conveying slide 4, and then reaches between the two vertical plates 31 through the feed port 331, that is, below the pressing head 3211. When the conveyor belt 12 conveys the bottle body to the bottom of the pressing head 3211, the capping cylinder 321 drives the pressing head 3211 to move downward, and the pressing head 3211 pushes the bottle cap downward, so that the bottle cap can be pressed on the bottle mouth of the bottle body to complete the capping operation. Among them, the feed port 331 only allows one bottle cap to pass through each time, and after the bottle cap under the pressing head 3211 completes the capping operation, the next bottle cap can pass through the feed port 331 to reach below the pressing head 3211, thereby completing the purpose of pressing the bottle caps one by one.

[0037] like Figure 2 and Figure 3 As shown, a blocking assembly is provided on the mounting plate 3 to prevent the bottle cap from falling downward after reaching the lower pressure head 3211. The blocking assembly includes two rotating shafts 5 respectively arranged on the side of the vertical plate 31 away from the lower pressure head 3211, one end of the rotating shaft 5 is rotatably connected to the mounting plate 3, and the other end is rotatably connected to the feed baffle 33. A cylinder 51 is fixedly sleeved on the rotating shaft 5, and a discharge baffle 52 is fixedly connected to the side of the cylinder 51 close to the conveyor belt 12, and the lengths of the two discharge baffles 52 extend to the lower pressure head 3211. Moreover, the length of the discharge baffle 52 on the side of the cylinder 51 away from the vertical plate 31 is greater than the length of the discharge baffle 52 on the side of the cylinder 51 close to the vertical plate 31. A protrusion 521 is also fixedly connected to the end of the discharge baffle 52 close to the vertical plate 31, and the protrusion 521 contacts the feed baffle 33, and when the protrusion 521 contacts the feed baffle 33, the discharge baffle 52 maintains a horizontal direction.

[0038] When the bottle cap passes through the feed port 331, it reaches above the two discharge baffles 52, and the discharge baffles 52 support the bottle cap and prevent it from falling down. When the capping cylinder 321 drives the lower pressure head 3211 to push the bottle cap downward, the discharge baffle 52 rotates, so that the bottle cap can move downward. After the bottle cap is covered on the bottle mouth of the bottle body, the capping cylinder 321 drives the lower pressure head 3211 to return to its original position upward. At the same time, the discharge baffle 52 is set on both sides of the cylinder 51. Due to the longer side, the weight is relatively large. Due to the weight difference of the discharge baffles 52 on both sides of the cylinder 51, the discharge baffle 52 also rotates upward after the lower pressure head 3211 is reset. The function of the protrusion 521 can make the discharge baffle 52 return to the horizontal position. When the pressing head 3211 moves up and down, its side surface is always in contact with the discharge baffle 52 and does not separate, so as to prevent the pressing head 3211 from being pressed by the discharge baffle 52 when moving upward, thereby causing damage to the machine.

[0039] like Figure 3 As shown, an end of the discharge baffle 52 close to the vertical plate 31 is provided with an arc surface 522, and the arc surface 522 is on the side of the discharge baffle 52 close to the lower pressure head 3211. When the bottle cap moves downward and pushes the discharge baffle 52 open, the bottle cap slides along the arc surface 522. The arc surface 522 can make the bottle cap move downward more smoothly when pushing the discharge baffle 52 open. The arc surface 522 can also be an inclined surface.

[0040] like Figure 4 As shown, a positioning block 35 is also bolted to the mounting plate 3, and the positioning block 35 is arranged in an arc shape near one end of the discharging baffle 52. The positioning block 35 is used to position the bottle cap so that the bottle cap can be directly below the pressing head 3211.

[0041] like Figure 1 and Figure 5 As shown, a positioning assembly for locking the position of the bottle body is provided on the conveyor belt 12. The positioning assembly includes a position sensor 6 fixed on a side plate 121 away from the column 2. The two side plates 121 are bolted and fixed with positioning cylinders 7 between the two columns 2, and the positioning cylinders 7 are arranged opposite to each other. A positioning plate 71 is fixed to the end of the piston rod of the positioning cylinder 7. The position sensor 6 is electrically connected to the two positioning cylinders 7.

[0042] When the bottle moves to the position sensor 6, the position sensor 6 receives an electrical signal and transmits the electrical signal to the positioning cylinder 7, which drives the positioning plate 71 to move away from the conveyor belt 12. When the bottle moves below the pressing head 3211, the positioning cylinder 7 drives the positioning plate 71 to move toward the conveyor belt 12, thereby clamping the bottle and locking the position of the bottle below the pressing head 3211, so that the capping process can be completed more accurately.

[0043] The column 2 is also provided with a lifting mechanism for adjusting the capping mechanism up and down. The lifting mechanism can adjust the distance between the capping mechanism and the conveyor belt 12, so as to adapt to bottles of different heights. Figure 2 As shown, the lifting mechanism includes a top plate 8, and both ends of the top plate 8 are respectively fixedly connected to one end of the two columns 2 away from the conveyor belt 12. A vertical lead screw 81 is rotatably connected to the top plate 8, and the lead screw 81 passes through and is threadedly connected to the mounting plate 3.

[0044] By rotating the lead screw 81, the lead screw 81 can be moved up and down, thereby driving the mounting plate 3 to move up and down, and the mounting plate 3 drives the capping mechanism to move up and down, thereby adapting to bottles of different heights.

[0045] like Figure 2 As shown, the mounting plate 3 is threadedly connected with a positioning rod 9 that abuts against the column 2. After the screw 81 is rotated to adjust the height of the mounting plate 3, the positioning rod 9 is twisted toward the column 2 to make the positioning rod 9 abut against the column 2, thereby locking the position of the mounting plate 3. When the gland structure needs to be adjusted, the positioning rod 9 is twisted in a direction away from the column 2.

[0046] like Figure 1 As shown, the vibration plate 41 is fixed on the upper sleeve 10, and the lower end of the upper sleeve 10 is sleeved with the lower sleeve 101, and the lower sleeve 101 is fixed to the ground. A vertical row of bolt holes 1011 is provided on the lower sleeve 101. The upper sleeve 10 and the lower sleeve 101 are fixed by bolts through the bolt holes 1011 at different positions. When adjusting the height of the pressure cover mechanism, it is necessary to unscrew the bolts fixing the upper sleeve 10 and the lower sleeve 101, and then when adjusting the pressure cover mechanism, the upper sleeve 10 slides along the inner wall of the lower sleeve 101. After adjusting the position of the pressure cover mechanism, the upper sleeve 10 and the lower sleeve 101 are fixed by bolts through the bolt holes 1011 of corresponding heights.

[0047] like Figure 1 As shown, a vertical support rod 34 is also provided between the mounting plate 3 and the conveying slide 4. The support rod 34 can support the conveying slide 4, and can also enable the conveying slide 4 to move up and down more stably when the capping mechanism moves up and down.

[0048] The implementation principle of an efficient and stable automatic capping device in the embodiment of the present application is as follows: when the position sensor 6 senses that the bottle body has passed, the positioning cylinder 7 drives the positioning plate 71 to move away from the conveyor belt 12. When the bottle body reaches below the lower pressure head 3211, the positioning cylinder 7 drives the positioning plate 71 to lock the position of the bottle body. The capping cylinder 321 drives the lower pressure head 3211 to push the bottle cap downward, and the bottle cap pushes the discharge baffle 52 to both sides, and then covers the bottle cap on the bottle mouth of the bottle body to complete the capping action. Then the capping cylinder 321 drives the lower pressure head 3211 to return to its original position upward. The discharge baffle 52 rotates to a horizontal direction.

[0049] When the height of the bottle body changes, unscrew the positioning rod 9, then unscrew the bolts between the upper sleeve and the lower sleeve 101, rotate the screw 81, adjust the gland structure to the required position, then fix the upper sleeve to the lower sleeve 101 with bolts, and then screw the positioning rod 9 until it abuts against the column 2.

[0050] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
