Description

TECHNICAL FIELD

[0001] The utility model relates to a capping device, especially to the technology that aluminium film cover falls to the bottle mouth. BACKGROUND

[0002] In the prior art, aluminium film cover can be used to seal the bottle mouth. Before the aluminium film cover is combined with the bottle mouth, the aluminium film is used to obtain the three-dimensional structure of the aluminium film cover through the stamping process. The flat circular aluminium film is stamped into the aluminium film cover with the overall disc structure. The middle of the aluminium film cover is circular structure, and the edge is the skirt structure perpendicular to the middle part. The technology of installing the aluminium film cover on the bottle mouth is implemented in a straight line capping mode. The bottle moves on the straight conveying path, and the aluminium film cover is dragged by the bottle mouth when passing through the output end of the cover supply part, and finally separates from the cover supply part. The aluminium film cover falls on the bottle mouth by gravity, and the capping operation of the aluminium film cover is completed.

[0003] In this capping technology, any conveying path can only serve the capping operation of the same bottle on the conveying path. The conveying speed of the conveying path has an upper limit, because the output of the cover supply part has an upper limit. That is, when the previous aluminium film cover is output, the subsequent aluminium film cover needs to pass through a period of time to reach the output end of the cover supply part. If the conveying speed of the bottle is too fast, part of the bottles will not have aluminium film cover matched with the bottle mouth when passing through the output end of the cover supply part. The capping rhythm does not match the conveying speed of the bottle, and part of the bottle mouth does not have aluminium film cover. Therefore, in the prior art, the capping efficiency of the single conveying path is limited. SUMMARY

[0004] The technical problem to be solved by the utility model is how to improve the capping efficiency of the single conveying path, and thus a capping device is obtained.

[0005] To solve the above technical problems, the utility model discloses the following technical scheme: capping device includes rotary conveying part, linear input part, linear output part, cover supply part I, cover supply part II, linear input part is equipped with linear conveying path I and linear output part is equipped with linear conveying path II, the rotary conveying part is equipped with arc conveying path I, one end of arc conveying path I is connected with linear conveying path I, the other end of arc conveying path I is connected with linear conveying path II, cover supply part I, cover supply part II all are located the top of arc conveying path I, cover supply part I, cover supply part II are in turn distributed along arc conveying path I and cover supply part I is located the upstream of cover supply part II, the output direction of cover supply part I, the output direction of cover supply part II all are tangent to arc conveying path I, the rotary conveying part includes handling assembly I, handling assembly II, guard plate I, cylindrical cam, carousel I, drive assembly, carousel I is connected drive assembly and is driven to do unidirectional rotation, cylindrical cam is stationary relative to drive assembly, curve groove I, curve groove II are equipped on cylindrical cam, curve groove I, curve groove II are distributed around the rotation center line of carousel I, handling assembly I, handling assembly II are in turn distributed on carousel I, handling assembly I is equipped with sliding sleeve, guide rod, object table I, bearing I, sliding sleeve is fixedly connected with carousel I, object table I, bearing I all are installed on guide rod, guide rod is slidably connected with sliding sleeve, bearing I is embedded in curve groove I, handling assembly II is equipped with sliding sleeve, guide rod, object table II, bearing II, sliding sleeve is fixedly connected with carousel I, object table II, bearing II all are installed on guide rod, guide rod is slidably connected with sliding sleeve, bearing II is embedded in curve groove II, the motion range of object table I, the motion range of object table II intersect with arc conveying path I, guard plate I is located the outside of arc conveying path I, curve groove I is equipped with translation segment I, lifting segment I, and translation segment I, lifting segment I are communicated, curve groove II is equipped with translation segment II, lifting segment II, and translation segment II, lifting segment II are communicated, lifting segment I, lifting segment II are distributed in the circumferential direction around cylindrical cam and are dislocated, lifting segment I is located the below of the output end of cover supply part I, lifting segment II is located the below of the output end of cover supply part II.

[0006] The technical scheme is to insert a horizontal arc-shaped conveying path on the original conveying path of the bottle, and the arc-shaped conveying path is constructed based on a rotating conveying structure. Two groups of carrying assemblies are arranged on the rotating conveying structure in an alternating manner, and the two groups of carrying assemblies can independently move according to the corresponding curve grooves of the cylindrical cam. After receiving the bottles, the two groups of carrying assemblies can independently move between any two adjacent bottles, for example, one bottle is lifted and the other bottle is at the original conveying height. The technical scheme has the technical effect of controlling the independent movement between adjacent bottles, so that the bottles entering the arc-shaped conveying path are naturally divided into two groups. Thanks to the distribution of the two cover supplying parts along the arc-shaped conveying path, the lifting positions of the adjacent bottles are arranged separately and correspond to the positions of the two cover supplying parts. When the bottle is lifted and passes through the output end of the cover supplying part, the aluminum film cover can be obtained from the cover supplying part. The movement speed of the bottle on the straight conveying path I, the arc-shaped conveying path I and the straight conveying path II is unchanged, but the movement states of the carrying assembly I and the carrying assembly II driven by the cylindrical cam are independent and coordinated, so that the bottles on the carrying assembly I and the carrying assembly II can continue the original conveying path without needing to be divided and maintaining the original movement speed, and the technical effect of lifting movement can be obtained in the same conveying path by in-path grouping control. The technical scheme significantly improves the capping efficiency of the original conveying path as a whole.

[0007] In order to match the faster bottle conveying speed, that is, high yield, the utility model sets up the transition structure between the straight conveying path and the arc-shaped conveying path. The transition structure is used to reduce the angular velocity of the bottle when turning. Since the too high angular velocity is not conducive to the smooth connection between the bottles in different paths, it is extremely likely to cause the bottle to be stuck due to the too large angular velocity. The transition structure for reducing the angular velocity also affects the design requirement of the minimum radius of the arc-shaped conveying path I. This is because the transition structure increases the design freedom of the straight conveying path relative to the arc-shaped conveying path I to form a connection relationship. The position design of the straight conveying path I and the straight conveying path II, that is, the aforementioned straight conveying path relative to the arc-shaped conveying path I, becomes flexible, thereby providing strong adaptability of the entire technical scheme in terms of site arrangement. The transition structure is specifically as follows. The capping device includes a rotating input part and a rotating output part. The rotating input part is provided with an arc-shaped conveying path II. The rotating output part is provided with an arc-shaped conveying path III. One end of the arc-shaped conveying path II is connected with the straight conveying path I, and the other end of the arc-shaped conveying path II is connected with one end of the arc-shaped conveying path I. One end of the arc-shaped conveying path III is connected with the straight conveying path II, and the other end of the arc-shaped conveying path III is connected with the other end of the arc-shaped conveying path I. The transition structure is also conducive to reducing the radius of the arc-shaped conveying path II, so that the entire capping device has the advantage of compact volume.

[0008] In order to match the spacing requirements between the bottles when the bottle carrying assembly I and the bottle carrying assembly II receive the bottles, a grouping assembly is arranged on the linear input component, the grouping assembly comprises a guardrail arranged on one side of the linear conveying path I and a variable spacing screw rod arranged on the other side of the linear conveying path I, and the grouping assembly is located at the end of the linear conveying path I. The grouping assembly can re-arrange the bottles on the linear input component which are not arranged at equal intervals into an equal interval arrangement state.

[0009] As a preferred embodiment of the technical solution, the extension direction of the linear conveying path I coincides with the extension direction of the linear conveying path II. With this structure, consistent working conditions are provided for the bottle conveying process, and the entire capping device can work in the best state.

[0010] In the technical solution, the distance between the carrier table I and the carrier table II relative to the rotating disc I changes, that is, the spatial position changes, but it is necessary to ensure that the carrier table I and the carrier table II maintain a consistent spatial posture relative to the rotating disc I, and in particular, the two cannot produce a self-rotation action, otherwise, the bottles cannot be connected in front and back on the conveying path, and it is extremely likely that the bottles will be stuck on the carrier table I and the carrier table II. Therefore, the technical solution also improves the specific structure of the carrying assembly I and the carrying assembly II. The carrying assembly I is provided with two guide rods and two sliding sleeves, the carrying assembly I is also provided with an L-shaped bearing seat I, one end of the guide rod is fixedly connected with the carrier table I, the other end of the guide rod is connected with the bearing seat I, the bearing I is installed on the bearing seat I, and the two guide rods of the carrying assembly I are arranged in sequence in the radial direction along the center line of the rotating disc I. The carrying assembly II is provided with two guide rods and two sliding sleeves, the carrying assembly II is also provided with an L-shaped bearing seat II, one end of the guide rod is fixedly connected with the carrier table II, the other end of the guide rod is connected with the bearing seat II, the bearing II is installed on the bearing seat II, and the two guide rods of the carrying assembly II are arranged in sequence in the radial direction along the center line of the rotating disc I. Both the carrying assembly I and the carrying assembly II have two guide rods, and the guide rods are distributed in the radial direction. This structure can prevent the self-rotation action, and the structure of the two guide rods helps to improve the structural strength.

[0011] The structural design of the carrying assembly I and the carrying assembly II is based on the same design idea, and both are in the same working area, but there is a difference in the working sequence, therefore, the specific structures of the two can adopt a universal design to realize part interchangeability and compatibility. Therefore, the length of the guide rod of the carrying assembly I is equal to the length of the guide rod of the carrying assembly II, and the mounting direction of the bearing seat I is opposite to the mounting direction of the bearing seat II. With this design, the carrying assembly I and the carrying assembly II can share parts, which is conducive to reducing production costs.

[0012] The utility model discloses adopt above technical scheme: capping device passes through the in -train marshalling control, sets up two capping stations on the conveying path of bottle, and the bottle carries out double -position capping operation under the condition of maintaining the original conveying speed and continuing the original conveying path, thereby improves the capping efficiency of single conveying path.

[0022] The first kind of embodiment of the utility model, as Figure 1 , 2 , 3, 4, 5, 6, 7, 8 shows.

[0023] Capping device by including rotating conveying part 1, straight line input part 2, rotating input part 3, straight line output part 4, rotating output part 5, cover supplying part I 6, cover supplying part II 7 and rack.

[0024] The rotating conveying component 1 comprises a carrying assembly I 8, a carrying assembly II 9, a guard plate I 10, a cylindrical cam 11, a rotating disc I 12 and a driving assembly. The guard plate I 10, the cylindrical cam 11 and the driving assembly are fixedly installed on the rack, and all of them are in a static state relative to the rack. The rotating disc I 12 is movably installed on the rack, and the rotating disc I 12 is drivingly connected with the driving assembly, so that the driving assembly can drive the rotating disc I 12 to rotate in one direction. After the rotating disc I 12 rotates, its spatial posture changes, but the relative position of the rotating disc I 12 on the rack does not change.

[0025] The cylindrical cam 11 is provided with a through hole in the middle for the transmission shaft structure on the rotating disc I 12, and after installation, the rotating disc I 12 is located in the middle of the cylindrical cam 11, and the center line of the rotating disc I 12 coincides with the center line of the cylindrical cam 11. The cylindrical cam 11 is provided with two curved grooves, which are curved groove I 13 and curved groove II 14. The curved groove I 13 and the curved groove II 14 are both distributed on the side surface of the cylindrical cam 11, and both are groove structures around the center line of the cylindrical cam 11, so the curved groove I 13 and the curved groove II 14 are distributed around the center line of the rotating disc I 12. The curved groove I 13 is provided with a translation section I 15 and a lifting section I 16, and the translation section I 15 and the lifting section I 16 are connected end to end, that is, one end of the translation section I 15 communicates with one end of the lifting section I 16, and the other end of the lifting section I 16 communicates with the other end of the translation section I 15. The curved groove II 14 is provided with a translation section II 17 and a lifting section II 18, and the translation section II 17 and the lifting section II 18 are connected end to end, that is, one end of the translation section II 17 communicates with one end of the lifting section II 18, and the other end of the lifting section II 18 communicates with the other end of the translation section II 17. The curved groove I 13 and the curved groove II 14 have the same overall structure, and the difference is that the distribution angles of the two on the cylindrical cam 11 are different, and the two are distributed in a staggered manner around the circumferential direction of the cylindrical cam 11. The staggered distribution feature is that the lifting section I 16 and the lifting section II 18 are distributed in a staggered manner around the circumferential direction of the cylindrical cam 11, because the lifting section I 16 protrudes from the translation section I 15 and the lifting section II 18 protrudes from the translation section II 17 in the direction parallel to the center line of the cylindrical cam 11, and the length of the translation section I 15 is greater than the length of the lifting section I 16, and the length of the translation section II 17 is greater than the length of the lifting section II 18.

[0026] The carrying assembly I 8 and the carrying assembly II 9 are alternately distributed on the rotating disc I 12 and arranged in a ring shape, and both are located at the edge of the rotating disc I 12. The curved groove I 13 serves the carrying assembly I 8, and the curved groove II 14 serves the carrying assembly I 8. The movement rhythm of the carrying assembly I 8 is relatively independent of the movement rhythm of the carrying assembly II 9, but the movement rhythm of the two is coordinated with each other and is related in the whole.

[0027] The carrying assembly I 8 and the carrying assembly II 9 adopt a common design, and the required parts are compatible and interchangeable. The carrying assembly I 8 is provided with a sliding sleeve, a guide rod, a carrier table I 19, a bearing I 20, and a bearing seat I 21. The carrying assembly I 8 has two sets of sliding block mechanisms composed of the guide rod and the sliding sleeve. The sliding sleeve is fixedly connected with the rotating disc I 12, the guide rod is slidingly connected with the sliding sleeve, the center line of the guide rod is parallel to the rotating center line of the rotating disc I 12, and the two guide rods of the carrying assembly I 8 are arranged in sequence in the radial direction of the rotating center line of the rotating disc I 12. The position relationship between the guide rod and the rotating disc I 12 is that one end of the guide rod is higher than the rotating disc I 12, and the other end of the guide rod is lower than the rotating disc I 12. The carrier table I 19 is provided with a carrier surface for supporting the bottle bottom and a notch for limiting the bottle body. One end of the guide rod is fixedly connected with the carrier table I 19, and the other end of the guide rod is connected with the bearing seat I 21. The bearing seat I 21 is in the shape of L as a whole, which is provided with a long side part and a short side part, wherein the long side part is connected with the guide rod, and the short side part is used for installing the bearing I 20. The carrying assembly II 9 is provided with a sliding sleeve, a guide rod, a carrier table II 22, a bearing II 23, and a bearing seat II 24. The carrying assembly II 9 has two sets of sliding block mechanisms composed of the guide rod and the sliding sleeve. The sliding sleeve is fixedly connected with the rotating disc I 12, the guide rod is slidingly connected with the sliding sleeve, the center line of the guide rod is parallel to the rotating center line of the rotating disc I 12, and the two guide rods of the carrying assembly II 9 are arranged in sequence in the radial direction of the rotating center line of the rotating disc I 12. The position relationship between the guide rod and the rotating disc I 12 is that one end of the guide rod is higher than the rotating disc I 12, and the other end of the guide rod is lower than the rotating disc I 12. The carrier table II 22 is provided with a carrier surface for supporting the bottle bottom and a notch for limiting the bottle body. One end of the guide rod is fixedly connected with the carrier table II 22, and the other end of the guide rod is connected with the bearing seat II 24. The bearing seat II 24 is in the shape of L as a whole, which is provided with a long side part and a short side part, wherein the long side part is connected with the guide rod, and the short side part is used for installing the bearing II 23. The sliding sleeve, the guide rod, the carrier table I 19, the bearing I 20, and the bearing seat I 21 of the carrying assembly I 8 have the same structure and size as the sliding sleeve, the guide rod, the carrier table II 22, the bearing II 23, and the bearing seat II 24 of the carrying assembly II 9, so the parts are compatible and interchangeable.

[0028] The bearing I 120 is embedded in the curved groove I 113, and the bearing II 223 is embedded in the curved groove II 214. After the rotation disc I 112 moves, the carrying assembly I 8 and the carrying assembly II 9 are driven to move. The bearing I 120 is guided by the curved groove I 113 to generate a force on the guide rod, so as to drive the guide rod of the carrying assembly I 8 to move relative to the sliding sleeve. Similarly, the bearing II 223 is guided by the curved groove II 214 to generate a force on the guide rod, so as to drive the guide rod of the carrying assembly II 9 to move relative to the sliding sleeve. When the bearing I 120 is in the translation section I 115 and the bearing II 223 is in the translation section II 217, the object table I 119 and the object table II 222 are at the same height and at a lower height. At this time, the height of the object table I 119 and the object table II 222 is recorded as the reference height. When the bearing I 120 is in the lifting section I 116 and the bearing II 223 is in the lifting section II 218, the object table I 119 and the object table II 222 are at the same height and at a higher height. At this time, the height of the object table I 119 and the object table II 222 is recorded as the capping height. The capping height is greater than the reference height.

[0029] The carrying assembly I 8 and the carrying assembly II 9 have structural differences due to different installation directions. Specifically, the installation direction of the bearing seat I 221 is opposite to the installation direction of the bearing seat II 224. The reason for the difference is that the curved groove I 113 and the curved groove II 214 are independent. Under the working condition, the curved groove I 113 is located above the curved groove II 214. In order to make the object table I 119 and the object table II 222 at the same reference height, the bearing seat I 221 and the bearing seat II 224 need to be assembled in opposite directions. In this way, the negative effect of the distance between the curved groove I 113 and the curved groove II 214 on obtaining the reference height can be offset.

[0030] The object table I 119 and the object table II 222 rotate, and the space they pass through is the ring-shaped movement range of the object table I 119 and the ring-shaped movement range of the object table II 222. The movement range of the object table I 119 is guided by the lifting section I 116 to have a protrusion along the direction parallel to the rotation center line of the rotation disc I 112, forming a lifting action. Similarly, the movement range of the object table II 222 is guided by the lifting section II 218 to have a protrusion along the direction parallel to the rotation center line of the rotation disc I 112, forming a lifting action. The two protrusions are distributed in a staggered manner around the circumferential direction of the cylindrical cam 11, and the positional relationship corresponds to the staggered relationship between the lifting section I 116 and the lifting section II 218.

[0031] The guard plate I 110 is located outside the movement range of the object table I 119 and the movement range of the object table II 222, and is located outside the protrusion structure of the movement range of the object table I 119 and the protrusion structure of the movement range of the object table II 222. The guard plate I 110 is used to limit the bottle body and prevent the bottle body from separating from the object table I 119 and the object table II 222.

[0032] The cover supplying part I 6 and the cover supplying part II 7 are installed on the frame. After installation, the cover supplying part I 6 and the cover supplying part II 7 are located above the turntable I 12. The lifting section I 16 is located below the output end of the cover supplying part I 6, and the lifting section II 18 is located below the output end of the cover supplying part II 7.

[0033] The movement range of the object table I 19 and the movement range of the object table II 22 are the arc-shaped conveying path I of the rotating conveying part 1 next to the inside of the guard plate I 10. The center of the arc-shaped conveying path I coincides with the rotation center line of the turntable I 12. The output end of the cover supplying part I 6 and the output end of the cover supplying part II 7 are along the conveying direction of the arc-shaped conveying path I, and the output direction of the cover supplying part I 6 is perpendicular to the radius of the arc-shaped conveying path I, and the output direction of the cover supplying part II 7 is perpendicular to the radius of the arc-shaped conveying path II, so the output direction of the cover supplying part I 6 and the output direction of the cover supplying part II 7 are tangent to the arc-shaped conveying path I.

[0034] The rotating input part 3 is provided with a guard plate II and a turntable II, the turntable II is provided with a bearing structure for receiving bottles, the distance between the bearing structures is equal to the distance between the object table I 19 and the object table II 22, the guard plate II is located outside the turntable II, and it is used to limit the bottles so that the bottles cannot be separated from the bearing structure. During installation, the turntable I 12 and the turntable II are partially overlapped in the vertical direction, the guard plate I 10 extends above the turntable II, and the guard plate II extends above the turntable I 12. The turntable II also rotates in one direction, and the rotation direction of the turntable II is opposite to the rotation direction of the turntable I 12. The movement range of the bearing structure of the turntable II is annular, and this movement range next to the inside of the guard plate II is the arc-shaped conveying path II of the rotating input part 3. The arc-shaped conveying path II connects with the arc-shaped conveying path I, and the arc-shaped conveying path I can receive bottles from the arc-shaped conveying path II.

[0035] The rotating output part 5 is provided with a guard plate III and a turntable III, the turntable III is provided with a bearing structure for receiving bottles, the distance between the bearing structures is equal to the distance between the object table I 19 and the object table II 22, the guard plate III is located outside the turntable III, and it is used to limit the bottles so that the bottles cannot be separated from the bearing structure. During installation, the turntable I 12 and the turntable III are partially overlapped in the vertical direction, the turntable III can be docked with the object table I 19 and the object table II 22, the guard plate I 10 extends above the turntable III, and the guard plate III extends above the turntable I 12. The turntable III also rotates in one direction, and the rotation direction of the turntable III is opposite to the rotation direction of the turntable I 12. The movement range of the bearing structure of the turntable III is annular, and this movement range next to the inside of the guard plate III is the arc-shaped conveying path III of the rotating output part 5. The arc-shaped conveying path III connects with the arc-shaped conveying path I, and the arc-shaped conveying path III can receive bottles from the arc-shaped conveying path I.

[0036] The straight line input component 2 is provided with a conveying chain, a grouping assembly, the grouping assembly is provided with a guardrail and a variable pitch screw. The conveying chain is distributed straightly, the guardrail is distributed on one side of the conveying chain, and the variable pitch screw is located on the other side of the conveying chain. After the variable pitch screw rotates, the spacing of the bottles can be adjusted according to the conveying rhythm of the conveying chain. The guard plate II extends above the conveying chain, and the rotating disc II also extends above the conveying chain. Above the conveying chain is the straight line conveying path I of the straight line input component 2, the straight line conveying path I is connected with the arc conveying path II, and the arc conveying path II can receive the bottles from the straight line conveying path I. The grouping assembly is located at the end of the straight line conveying path I, next to the position of the arc conveying path II. The straight line conveying output component is provided with a conveying chain, and the conveying chain is distributed straightly. The guard plate II extends above the conveying chain, and the rotating disc III extends above the conveying chain. Above the conveying chain is the straight line conveying path II of the straight line conveying output component, the straight line conveying path II is connected with the arc conveying path III, and the straight line conveying path II can receive the bottles from the arc conveying path III. The extension direction of the straight line conveying path I coincides with the extension direction of the straight line conveying path II.

[0037] In use, the bottles will enter the straight line conveying path I, the arc conveying path II, the arc conveying path I, the arc conveying path III, and the straight line conveying path II in sequence. The bottles are forced to adjust the spacing by the grouping assembly at the end of the straight line conveying path I, so that whether the bottles on the straight line conveying path I are arranged at intervals or not, the spacing of the bottles can be ensured to meet the conveying requirements of the rotating conveying component 1, the rotating input component 3 and the rotating output component 5 after adjustment by the grouping assembly. After the bottles enter the arc conveying path I, the bottles will be placed on the carrying assembly I 8 and the carrying assembly II 9. The cap supplying component I 6 and the cap supplying component II 7 are located above the arc conveying path I.

[0038] When the bottles enter the arc conveying path I, the following actions will occur.

[0039] When the bearing 120 of the carrying assembly 18 enters the lifting section 116, the bottle on the carrier table 119 is lifted to the capping height, and after the bottle passes the output end of the capping component 6, the bottle mouth pulls an aluminum film cap, and the aluminum film cap covers the bottle mouth; at this time, the bearing 123 of the carrying assembly 29 adjacent to the carrying assembly 18 is in the translation section 117, and the bottle on the carrier table 122 is at the reference height, that is, the original conveying height of the bottle. When the bearing 123 of the carrying assembly 29 enters the lifting section 118, the bottle on the carrier table 122 is lifted to the capping height, and after the bottle passes the output end of the capping component 7, the bottle mouth pulls an aluminum film cap, and the aluminum film cap covers the bottle mouth; at this time, the bearing 120 of the carrying assembly 18 adjacent to the carrying assembly 29 is in the translation section 115, and the bottle on the carrier table 119 is at the reference height, that is, the original conveying height of the bottle. The two lifting actions are performed separately, so that two capping operation actions can be obtained on the same conveying path, thereby significantly improving the working efficiency of the capping operation.

[0040] The arc-shaped conveying path 1 only occupies part of the movement range of the carrier table 119 and the movement range of the carrier table 122, and the two are intersected in space. Since the capping components 6 and 7 are sequentially distributed along the arc-shaped conveying path 1 and the capping component 6 is located upstream of the capping component 7, there is a timing feature between the adjacent carrier tables 119 and 122 that the bottle on the carrier table 119 is always lifted first and the bottle on the carrier table 122 is always lifted later. However, the two lifting actions can be generated synchronously or asynchronously on the entire arc-shaped conveying path 1, which depends on the production needs, and the embodiment adopts an asynchronous mode. The bottle will return to the reference height, that is, the original conveying height, before leaving the arc-shaped conveying path 1, and the bottle finally capped with the aluminum film cap is output outward through the linear conveying path 2.

[0041] The second embodiment of the utility model, the difference between this embodiment and the first embodiment is that the capping device is not provided with a rotary input component and a rotary output component, and the rotary conveying component is directly connected with the linear input component and the linear output component. In this embodiment, two guide plates need to be configured, one end of one of the guide plates extends into the upper side of the turntable 1, the other end of one of the guide plates extends into the upper side of the conveying chain of the linear input component 2, one end of the other guide plate extends into the upper side of the turntable 1, and the other end of one of the guide plates extends into the upper side of the conveying chain of the linear conveying output component. The guide plate is used to guide the bottle to separate from the linear conveying path 1 and enter the arc-shaped conveying path 1, or guide the bottle to separate from the arc-shaped conveying path 1 and enter the linear conveying path 2.

[0042] The grouping assembly in the above embodiments is to provide grouping operation when the bottles cannot be kept at effective spacing. In the case that the bottles can be kept at spacing, the structure of the grouping assembly can be omitted, thus obtaining other two embodiments.

[0043] The straight conveying path I and the straight conveying path II in the above embodiments can also be provided by the same conveying chain, so that the extension directions of the two are necessarily coincident. Such design can reduce the use of driving assemblies, so that the complexity of mechanical design is reduced, thus obtaining other four embodiments.
