Since the cover rolling part only needs to drive the rotating shaft to swing through the connecting rod and the sliding block, the transmission structure is relatively simple, and the cost is reduced.

Description

Technical Field

[0001] This application relates to the field of automated production equipment for medical consumables, and in particular to a capping mechanism and an automatic capping machine. Background Technology

[0002] In the filling production line of containers for food, medicine and other products, a capping machine is generally used to cap and seal the filled bottles.

[0003] However, current capping machines mainly use a fixed cap and bottle body, and the capping operation is achieved by rotating the capping component around the cap multiple times. The motion structure is complex and the cost is high. Moreover, it can only cap one container bottle at a time, resulting in low capping efficiency. Utility Model Content

[0004] The purpose of this application is to provide a capping mechanism and an automatic capping machine, which has a simple motion structure and reduced cost, and can batch cap multiple containers, thus increasing capping efficiency.

[0005] The embodiments of this application can be implemented as follows:

[0006] In a first aspect, embodiments of this application provide a capping mechanism, including a mounting plate, a capping assembly, and a capping assembly;

[0007] The capping assembly includes a capping motor and multiple cap clips;

[0008] The capping component is rotatably mounted on the mounting plate; the capping motor is fixed to the mounting plate and is connected to one end of each capping component, driving each capping component to rotate synchronously; the other end of the capping component is used for inserting the bottle cap.

[0009] The capping assembly includes a capping drive, a slider, multiple connecting rods, multiple rotating shafts, and multiple capping parts;

[0010] The slider is disposed on the mounting plate; the connecting rod is movably connected to the slider; the rotating shaft is rotatably inserted through the mounting plate, and one end of the rotating shaft is connected to the connecting rod, and the other end is connected to the cover; wherein, each cover corresponds to one cover;

[0011] The capping drive is fixed to the mounting plate and connected to the slider. The capping drive is used to drive the slider to slide relative to the mounting plate, so that the connecting rod drives the rotating shaft to swing, thereby causing each capping component to swing synchronously to move closer to or away from the corresponding capping assembly, and thus causing the capping component to abut against the bottle cap or separate from the bottle cap.

[0012] In the above implementation, a capping motor drives each capping component to rotate simultaneously, which can achieve batch driving of multiple bottle caps while reducing the number of power sources and lowering costs. A capping drive component drives a slider to slide on a mounting plate. Since the connecting rod and slider are movably connected, they can slide and rotate relative to each other. When the slider moves, the connecting rod drives the rotating shaft to rotate, thereby causing the capping component mounted on the other end of the rotating shaft to swing. This achieves synchronous swinging of each capping component, which then moves synchronously closer to or away from the corresponding capping component. When the capping component approaches the capping component, it can abut against the peripheral wall of the bottle cap. Thus, when the capping component drives the bottle cap to rotate, batch capping operation can be achieved, improving capping efficiency. After capping is completed, the capping component is driven synchronously away from each capping component to separate from each bottle cap, making it easy to remove these capped containers. Since the capping component only needs to drive the rotating shaft to swing through the connecting rod and slider, the transmission structure is relatively simple, which also reduces costs.

[0013] In an optional embodiment, one of the connecting rod and the slider is provided with an oblong hole, and the other is provided with a mating post. The mating post extends into the oblong hole and is capable of rotating and / or sliding within the oblong hole.

[0014] The above-described embodiment achieves a movable connection between the connecting rod and the slider by cooperating with the column and the waist-shaped hole. In this way, when the slider is driven by the capping drive to slide and translate on the mounting plate, the cooperating column will slide and rotate in the waist-shaped hole, thereby converting the linear power into the torque that drives the rotating shaft to swing.

[0015] In an optional embodiment, the connecting rod includes a mating part and a fitting part connected together, the mating part being movably connected to the slider;

[0016] The assembly has a first connecting part and a second connecting part that are opposite each other, and the first connecting part and the second connecting part together clamp the rotating shaft.

[0017] In the above embodiment, the connecting rod is considered as two parts: a mating part and a fitting part. The mating part is used to movably connect with the slider. The gap between the first connecting part and the second connecting part in the fitting part can be used for the rotating shaft to pass through, which is beneficial to the combination of the rotating shaft and the connecting rod. Then, by having the first connecting part and the second connecting part clamp the rotating shaft together, the entire connecting rod can be fixed relative to the rotating shaft.

[0018] In an optional embodiment, the first connecting part and the second connecting part each have a semi-circular arc groove on their opposite sides, and the two arc grooves together form a fitting hole for the rotating shaft to pass through.

[0019] In the above embodiment, the arc-shaped grooves designed on the opposite sides of the first connecting part and the second connecting part are used to jointly form the fitting hole, so as to match the shape of the rotating shaft, ensure the contact area between the connecting rod and the rotating shaft, and thus improve the reliability of the connection and fixation of the two.

[0020] In an optional embodiment, the first connecting portion is provided with a through hole, the through hole penetrating the side of the first connecting portion near the second connecting portion;

[0021] The second connecting portion is provided with a threaded hole, which penetrates the side of the second connecting portion near the first connecting portion;

[0022] The screw passes through the through hole and connects to the threaded hole.

[0023] In the above embodiment, by providing a through hole on the first connecting part and a threaded hole on the second connecting part, the first connecting part and the second connecting part can be locked by the screw passing through the through hole and connecting to the threaded hole. This can achieve relative fixation of the connecting rod and the rotating shaft, and the connecting rod and the rotating shaft can be easily separated after the screw is removed, making disassembly and assembly convenient.

[0024] In an optional embodiment, the capping assembly further includes a transmission element, a support roller, a driving roller, and a driven roller;

[0025] The drive wheel is coaxially connected to the output shaft of the capping motor;

[0026] The number of driven wheels is the same as the number of the cover pieces, and the driven wheels are coaxially connected to one end of the cover piece;

[0027] The support roller is rotatably mounted on the mounting plate, and there is at least one support roller between every two adjacent drive wheels;

[0028] The transmission component includes a timing belt or chain, and the transmission component is wound around the driving wheel, the driven wheel, and the support roller.

[0029] The above-described implementation uses belt or chain drive to transmit the torque of the capping motor to each drive shaft, causing each drive shaft to rotate the cap clamps. This enables simultaneous rotation of caps in batches, facilitating batch capping operations, improving efficiency. Furthermore, belt and chain drives offer high transmission efficiency and low cost. Additionally, the support rollers tension the transmission components, ensuring close contact between the transmission components and the driven wheels, thus guaranteeing transmission efficiency.

[0030] In an optional embodiment, the support roller is closer to the driving roller than the driven roller;

[0031] The transmission element is located around the region of the driven wheel away from the driving wheel and the region of the support roller near the driving wheel.

[0032] In the above embodiments, the transmission component can be wavy to ensure close contact between the transmission component and the driven and driving wheels; moreover, the support roller is positioned closer to the driving wheel than the driven wheel, which can make reasonable use of the space on the mounting plate and improve space utilization.

[0033] In an optional embodiment, the capping component includes a swing arm and a capping wheel rotatably connected to one end of the swing arm;

[0034] The other end of the swing arm is connected to the other end of the rotating shaft.

[0035] In the above embodiment, the capping roller and the rotating shaft are connected by a swing arm. The rotating shaft can drive the capping roller to make an arc-shaped movement, so that the capping roller abuts against or moves away from the bottle cap. Since the capping roller is rotatably connected to one end of the swing arm, the capping operation can be achieved by rotating the bottle cap when the capping roller abuts against the bottle cap.

[0036] In an optional embodiment, the capping mechanism further includes a plurality of dust blowing components, which are mounted on the mounting plate and correspond one-to-one with the capping component. The dust blowing components are used to blow air onto the bottle cap.

[0037] The above-described implementation method uses a blower to blow air onto the bottle cap, ensuring cleanliness during the capping process and preventing contamination of the medicine in the bottle.

[0038] In an optional embodiment, the capping motor, the capping drive, the slider, and the connecting rod are located on the same side of the mounting plate.

[0039] In the above-described embodiment, since the capping motor and the slider are located on the same side of the mounting plate, the space on the mounting plate can be used in a reasonable way, thereby improving the space utilization rate and thus improving the structural compactness.

[0040] In an optional embodiment, the mounting plate is provided with a first boss and / or a second boss, the cover is rotatably inserted through the first boss, and the rotating shaft is rotatably inserted through the second boss.

[0041] In the above embodiments, the first boss increases the axial length of the rotating engagement of the cover member on the mounting plate, thereby increasing the installation stability and rotational stability of the cover member. Similarly, the second boss increases the axial length of the rotating engagement of the cover member on the mounting plate, thereby increasing the installation stability and rotational stability of the cover member.

[0042] In an optional embodiment, the cap clamp includes a drive shaft and a cap clamp;

[0043] The drive shaft is rotatably mounted on the mounting plate;

[0044] The screw cap motor is connected to one end of each of the drive shafts in a transmission connection.

[0045] The bottle cap clamp is coaxially connected to the other end of the drive shaft; the bottle cap clamp is used to insert the bottle cap.

[0046] Each of the aforementioned capping components corresponds to one of the aforementioned cap clamps;

[0047] Driven by the capping drive, each capping component can synchronously move closer to or further away from the corresponding cap clamp.

[0048] In the above embodiment, the torque of the capping motor is transmitted to the cap chuck through the drive shaft, so that the cap chuck can rotate with the cap. Under the drive of the capping drive, each capping component can synchronously approach or move away from the corresponding cap chuck, and synchronously abut against or separate from the cap, thereby realizing batch capping.

[0049] Secondly, embodiments of this application provide an automatic capping machine, including a bottle-carrying mechanism and the capping mechanism of the above-described embodiments;

[0050] The bottle-carrying mechanism includes a bottle-carrying platform and a plurality of bottle-carrying clamps rotatably mounted on the bottle-carrying platform. The bottle-carrying clamps are used to clamp the bottle body, and each bottle-carrying clamp corresponds to a cap piece.

[0051] The bottle carrier platform is connected to a bottle feeding mechanism, which drives the bottle carrier platform to move the bottle clamp closer to or away from the cap holder; and / or, the mounting plate is connected to a cap feeding mechanism, which drives the mounting plate to move the cap holder closer to or away from the bottle carrier clamp.

[0052] The above-described embodiments have the corresponding structure and beneficial effects of the capping mechanism. When the capping assembly rotates with the cap, the bottle body and the bottle carrier also rotate with the cap to ensure the relative stillness between the bottle body and the cap, thereby ensuring the reliability of the cap and bottle body assembly. The cap feeding mechanism and / or bottle feeding mechanism can be used to move the cap clamping component and the bottle carrier closer or further apart, so that the cap can be placed on the platform for capping operation and sufficient space is left between the cap clamping component and the bottle carrier after capping to facilitate the removal of the assembled container bottle, thus realizing automated capping operation.

[0053] In an optional embodiment, the bottle-carrying mechanism further includes a rotating sleeve mounted on the bottle-carrying platform;

[0054] The bottle holder has a portion that is housed within the rotating sleeve, and a bearing is installed between the outer peripheral wall of the bottle holder and the inner peripheral wall of the rotating sleeve.

[0055] In the above embodiment, a rotating sleeve is installed on the bottle carrier platform, and the bottle carrier clamp is installed in the rotating sleeve through a bearing to realize the rotatable setting of the bottle carrier clamp on the bottle carrier platform. The bearing can ensure the accuracy and smoothness of the bottle carrier clamp and the bottle body during rotation. Attached Figure Description

[0073] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0074] refer to Figure 1 and Figure 2 This application discloses an automatic capping machine, including a bottle carrier mechanism 200 and a capping mechanism 100;

[0075] The capping mechanism 100 includes a mounting plate 110, a capping assembly 130, and a capping assembly 120. The mounting plate 110 serves as a carrier for the capping assembly 130 and the capping assembly 120. The capping assembly 130 is used to insert multiple bottle caps 500 and simultaneously drive each bottle cap 500 to rotate synchronously. The capping assembly 120 is used to simultaneously push against the peripheral wall of each bottle cap 500 so that the bottle cap 500 can be pressed into the annular groove at the top of the bottle body 600, thereby realizing batch capping operation.

[0076] refer to Figure 3The bottle-carrying mechanism 200 includes a bottle-carrying platform 210 and a bottle-carrying clamp 220 rotatably mounted on the bottle-carrying platform 210. The bottle-carrying clamp 220 is used to clamp the bottle body 600. In this way, when the capping assembly 130 rotates with the cap 500, the bottle body 600 and the bottle-carrying clamp 220 will also rotate with the cap 500 to ensure the relative stillness between the bottle body 600 and the cap 500, thereby ensuring the reliability of the assembly of the cap 500 and the bottle body 600.

[0077] For details, please refer to the following: Figure 4 The bottle-carrying mechanism 200 also includes a rotating sleeve 230, which is mounted on the bottle-carrying platform 210; a portion of the bottle-carrying clamp 220 is housed within the rotating sleeve 230, and a bearing 240 is installed between the outer peripheral wall of the bottle-carrying clamp 220 and the inner peripheral wall of the rotating sleeve 230.

[0078] Thus, by installing a rotating sleeve 230 on the bottle carrier stage 210, the bottle carrier clamp 220 is installed inside the rotating sleeve 230 via a bearing 240, so as to realize the rotatable setting of the bottle carrier clamp 220 on the bottle carrier stage 210. The bearing 240 can ensure the accuracy and smoothness of the bottle carrier clamp 220 and the bottle body 600 when rotating.

[0079] The bottle holder 220 can be a sleeve-shaped structure with a bottle holder hole 221 coaxial with itself. The bottle body 600 is inserted into the bottle holder hole 221 to clamp the bottle body 600.

[0080] The bottle-carrying hole 221 can be a stepped hole, with the larger diameter portion located away from the bottle-carrying stage 210, which facilitates the alignment and insertion of the bottle body 600. A flexible pad can be attached to the inner wall of the bottle-carrying hole 221 to increase the clamping force on the bottle body 600 while preventing damage to the bottle-carrying clamp 220 and the bottle body 600.

[0081] To achieve the assembly of bottle body 600 and cap 500, the automatic capping machine also includes a bottle feeding mechanism 300 and / or a cap feeding mechanism 400 (see further details). Figure 1 and Figure 2 The bottle feeding mechanism 300 is used to drive the bottle carrier platform 210 to move the bottle carrier clamp 220 closer to or away from the capping assembly 130; the cap feeding mechanism 400 is used to drive the mounting plate 110 to move the capping assembly 130 closer to or away from the bottle carrier clamp 220.

[0082] In this way, the cap feeding mechanism 400 and / or the bottle feeding mechanism 300 can move closer to or further away from the bottle carrier platform 210, so that the bottle cap 500 can be placed on the platform for capping operation, and after capping, sufficient space is left between the capping assembly 130 and the bottle carrier clamp 220 to facilitate the removal of the assembled container bottle, thus realizing automated capping operation.

[0083] Continue to refer to Figure 3The bottle feeding mechanism 300 includes a bottle feeding support 310, a bottle feeding push rod 330, a bottle feeding motor 320, and a bottle feeding reducer. The bottle feeding motor 320 is fixed on the bottle feeding support 310. The bottle feeding motor 320 is connected to the bottle feeding push rod 330 through the bottle feeding reducer. The bottle feeding push rod 330 is connected to the bottle carrying platform 210. The bottle feeding reducer can be a gear rack pair or a ball screw pair, as long as it is a component that can convert the torque of the bottle feeding motor 320 into linear driving force. In this way, when the bottle feeding motor 320 is running, it can drive the push rod to move the entire bottle carrying mechanism 200 in a linear motion to move closer to or away from the capping mechanism 100.

[0084] refer to Figure 5 The cap feeding mechanism 400 includes a cap feeding support 410, a cap feeding push rod 430, a cap feeding motor 420, and a cap feeding reducer. The cap feeding motor 420 is fixed on the cap feeding support 410 and is connected to the cap feeding push rod 430 via the cap feeding reducer. The cap feeding push rod 430 is connected to the mounting plate 110. The cap feeding reducer can be a gear and rack pair or a ball screw pair, as long as it is a component that can convert the torque of the cap feeding motor 420 into linear driving force. In this way, when the cap feeding motor 420 is running, it can drive the cap feeding push rod 430 to move the entire capping mechanism 100 in a linear motion to move closer to or away from the bottle carrying mechanism 200.

[0085] refer to Figures 6-8 The capping assembly 130 includes a capping motor 131 and a plurality of cap clips 138;

[0086] The cap 138 is rotatably mounted on the mounting plate 110; the capping motor 131 is fixed to the mounting plate 110 and is connected to one end of each cap 138 to drive each cap 138 to rotate synchronously; the other end of the cap 138 is used for the bottle cap 500 to be inserted.

[0087] The capping assembly 120 includes a capping drive 121, a slider 123, multiple connecting rods 122, multiple rotating shafts 124, and multiple capping parts 125;

[0088] The slider 123 is mounted on the mounting plate 110; the connecting rod 122 is movably connected to the slider 123; the rotating shaft 124 is rotatably mounted on the mounting plate 110, and one end of the rotating shaft 124 is connected to the connecting rod 122, and the other end is connected to the capping component 125; wherein, each capping component 125 corresponds to one capping component 138, and correspondingly, the bottle carrier 220 corresponds one-to-one with the capping component 138.

[0089] The capping drive 121 is fixed to the mounting plate 110 and connected to the slider 123. The capping drive 121 is used to drive the slider 123 to slide relative to the mounting plate 110, so that the connecting rod 122 drives the rotating shaft 124 to swing, thereby causing each capping component 125 to swing synchronously to approach or move away from the corresponding capping assembly 130, and thus causing the capping component 125 to abut against the bottle cap 500 or separate from the bottle cap 500.

[0090] In this way, the capping motor 131 drives each capping component 138 to rotate simultaneously, which can achieve batch driving of multiple bottle caps 500 to rotate while reducing the number of power sources and lowering costs. The capping drive component 121 drives the slider 123 to slide on the mounting plate 110. Since the connecting rod 122 and the slider 123 are movably connected, the connecting rod 122 and the slider 123 can slide and rotate relative to each other. Thus, when the slider 123 translates, the connecting rod 122 can drive the rotating shaft 124 to rotate, thereby causing the capping component 125 mounted on the other end of the rotating shaft 124 to swing, thereby achieving synchronous rotation of each capping component 125. The capping component 125 swings, thus synchronously approaching or moving away from the corresponding capping component 138. When the capping component 125 approaches the capping component 138, it can abut against the peripheral wall of the bottle cap 500. In this way, when the capping component 138 drives the bottle cap 500 to rotate, batch capping operation can be achieved, improving capping efficiency. After capping is completed, the capping component 125 is synchronously driven away from each capping component 125 to separate from each bottle cap 500, so that these capped containers can be removed. Since the capping component 125 only needs to drive the rotating shaft 124 to swing through the connecting rod 122 and the slider 123, the transmission structure is relatively simple and the cost is reduced.

[0091] The bottle feeding mechanism 300 drives the bottle carrier platform 210 to move the bottle holder 220 closer to or further away from the cap holder 138; the cap feeding mechanism 400 drives the mounting plate 110 to move the cap holder 138 closer to or further away from the bottle holder 220. This allows the cap holder 138 and the bottle holder 220 to move closer or further apart, so that the bottle cap 500 can be placed on the platform for capping operation, and after capping, sufficient space is left between the cap holder 138 and the bottle holder 220 to facilitate the removal of the assembled container bottle, thus realizing automated capping operation.

[0092] The mounting plate 110 is provided with a first boss 111 and / or a second boss 112. The cover 138 is rotatably inserted through the first boss 111, and the rotating shaft 124 is rotatably inserted through the second boss 112. The first boss 111 increases the axial length of the rotational engagement of the cover 138 on the mounting plate 110, thereby increasing the installation stability and rotational stability of the cover 138. The second boss 112 increases the axial length of the rotational engagement of the cover 125 on the mounting plate 110, thereby increasing the installation stability and rotational stability of the cover 125.

[0093] For more details, please refer to the following: Figure 6 and Figure 8 The capping assembly 130 also includes a transmission component 134, a support roller 137, a drive roller, and a driven roller 136; the drive roller is coaxially connected to the output shaft of the capping motor 131; the number of driven rollers 136 is the same as the number of cap clamping components 138, and the driven rollers 136 are coaxially connected to one end of the cap clamping component 138; the support roller 137 is rotatably mounted on the mounting plate 110, and there is at least one support roller 137 between every two adjacent drive rollers; the transmission component 134 includes a timing belt or a chain, and the transmission component 134 is wound around the drive roller, the driven roller 136, and the support roller 137.

[0094] Thus, by employing belt or chain drive, the torque of the capping motor 131 is transmitted to each drive shaft 132, causing each drive shaft 132 to rotate each cap clamp 133. This enables the simultaneous rotation of caps 500 in batches, thereby achieving batch capping operations, improving efficiency. Moreover, belt and chain drives offer high transmission efficiency and low cost. Simultaneously, the support roller 137 can tension the transmission component 134, ensuring close contact between the transmission component 134 and the driven wheel 136, guaranteeing transmission efficiency.

[0095] In this configuration, the support roller 137 is closer to the driving wheel than the driven wheel 136; the transmission component 134 is wrapped around the area of ​​the driven wheel 136 away from the driving wheel and the area of ​​the support roller 137 closer to the driving wheel. This allows the transmission component 134 to be wavy, ensuring close contact between the transmission component 134, the driven wheel 136, and the driving wheel; furthermore, the closer placement of the support roller 137 to the driving wheel allows for efficient use of the space on the mounting plate 110, improving space utilization.

[0096] The capping motor 131, the capping drive 121, the slider 123, and the connecting rod 122 are located on the same side of the mounting plate 110. This makes reasonable use of the space on the mounting plate 110, improves the space utilization rate, and thus improves the structural compactness.

[0097] The cap clamping component 138 includes a drive shaft 132 and a cap clamp 133; the drive shaft 132 is rotatably mounted on the mounting plate 110; the capping motor 131 is connected to one end of each drive shaft 132; the cap clamp 133 is coaxially connected to the other end of the drive shaft 132; the cap clamp 133 is used for the cap 500 to be clamped in; each capping component 125 corresponds to one cap clamp 133; under the drive of the capping drive component 121, each capping component 125 can synchronously move closer to or away from the corresponding cap clamp 133.

[0098] Thus, the torque of the capping motor 131 is transmitted to the cap chuck 133 via the drive shaft 132, so that the cap chuck 133 can rotate with the cap 500. Under the drive of the capping drive 121, each capping component 125 can synchronously approach or move away from the corresponding cap chuck 133, and synchronously abut against or separate from the cap 500, thereby realizing batch capping.

[0099] Of course, in some embodiments, the capping motor 131 may also use a two-stage or higher gear transmission to drive the various transmission shafts 132 to rotate synchronously.

[0100] Continue to refer to Figure 7 The capping mechanism 100 also includes multiple dust blowing components 140, which are mounted on the mounting plate 110. Each dust blowing component 140 corresponds to a capping component 138, and the dust blowing component 140 is used to blow air onto the bottle cap 500.

[0101] By blowing air onto each bottle cap 500 using the blower 140, cleanliness can be ensured during the capping process, thus preventing contamination of the medicine liquid in the bottle 600.

[0102] The number of dust blowing components 140 is the same as the number of cap clipping components 138 and cap crimping components 125. The dust blowing components 140 correspond one-to-one with the cap clipping components 138 to ensure that each bottle cap 500 can be cleaned.

[0103] In some embodiments, one of the connecting rod 122 and the slider 123 is provided with a waist-shaped hole 1220, and the other is provided with a mating post 1230. The mating post 1230 extends into the waist-shaped hole 1220 and can rotate and / or slide within the waist-shaped hole 1220.

[0104] In this way, the movable connection between the connecting rod 122 and the slider 123 is achieved by the cooperation of the mating post 1230 and the waist-shaped hole 1220. When the slider 123 is driven by the capping drive 121 to slide and translate on the mounting plate 110, the mating post 1230 will slide and rotate in the waist-shaped hole 1220, thereby converting the linear power into the torque that drives the rotating shaft 124 to swing.

[0105] For example, in Figure 8 and Figure 9 In the first embodiment, a slotted hole 1220 is provided on the connecting rod 122, and a mating post 1230 is provided on the sliding plate. The number of mating posts 1230 is the same as the number of connecting rods 122. In some embodiments not shown, the mating post 1230 can be provided on the connecting rod 122, and a corresponding number of slotted holes 1220 can be provided on the sliding plate.

[0106] Specifically, refer to Figure 9The connecting rod 122 includes a mating part 1221 and a sleeve part 1222 connected together. The mating part 1221 is movably connected to the slider 123. The sleeve part 1222 has a first connecting part 1223 and a second connecting part 1224 opposite to each other. The first connecting part 1223 and the second connecting part 1224 together clamp the rotating shaft 124.

[0107] The connecting rod 122 can be considered as two parts: a mating part 1221 and a fitting part 1222. The mating part 1221 is used to movably connect with the slider 123. The gap between the first connecting part 1223 and the second connecting part 1224 in the fitting part 1222 can be used to allow the rotating shaft 124 to pass through, which is beneficial to the combination of the rotating shaft 124 and the connecting rod 122. Then, by having the first connecting part 1223 and the second connecting part 1224 clamp the rotating shaft 124 together, the entire connecting rod 122 can be fixed relative to the rotating shaft 124.

[0108] The first connecting part 1223 and the second connecting part 1224 each have a semi-circular arc groove on their opposite sides. The two arc grooves together form a fitting hole 1225 for the rotating shaft 124 to pass through. In this way, the arc grooves designed on the opposite sides of the first connecting part 1223 and the second connecting part 1224 together form the fitting hole 1225, which is adapted to the shape of the rotating shaft 124, ensuring the contact area between the connecting rod 122 and the rotating shaft 124, thereby improving the reliability of the connection and fixation between the two.

[0109] To achieve relative fixation between the connecting rod 122 and the rotating shaft 124, the first connecting part 1223 is provided with a through hole 1226, which penetrates the side of the first connecting part 1223 near the second connecting part 1224; the second connecting part 1224 is provided with a threaded hole, which penetrates the side of the second connecting part 1224 near the first connecting part 1223; a screw passes through the through hole 1226 and is connected to the threaded hole.

[0110] In this way, by providing a through hole 1226 on the first connecting part 1223 and a threaded hole on the second connecting part 1224, the screw can be inserted through the through hole 1226 and connected to the threaded hole to lock the first connecting part 1223 and the second connecting part 1224. This achieves relative fixation of the connecting rod 122 and the rotating shaft 124. Moreover, the connecting rod 122 and the rotating shaft 124 can be easily separated after the screw is removed, making disassembly and assembly convenient.

[0111] Of course, in some embodiments, the connecting rod 122 and the rotating shaft 124 can also be combined together by welding, integral molding, or other methods.

[0112] Continue to refer to Figure 7 and Figure 9The capping component 125 includes a swing arm 1250 and a capping roller 1251 rotatably connected to one end of the swing arm 1250; the other end of the swing arm 1250 is connected to the other end of the rotating shaft 124. The swing arm 1250 connects the capping roller 1251 and the rotating shaft 124, allowing the rotating shaft 124 to drive the capping roller 1251 in an arc-shaped motion, causing the capping roller 1251 to abut against or move away from the bottle cap 500. Since the capping roller 1251 is rotatably connected to one end of the swing arm 1250, when the capping roller 1251 abuts against the bottle cap 500, the capping operation is achieved by rotating the bottle cap 500.

[0113] In summary, the embodiments of this application disclose a capping mechanism 100 and an automatic capping machine, which have a simple motion structure and reduced costs, and can batch cap multiple containers, thus increasing capping efficiency.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
