DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] In order to facilitate the assembly of the screw cap and the bottle body and improve production efficiency and convenience, as an embodiment of the present invention, Figure 1 , Figure 2 As shown, a fully automatic capping machine described in the present invention comprises a horizontally arranged conveyor belt 1 for conveying bottle bodies, two groups of baffles 2 are arranged on the outer side of the conveyor belt 1, and the bottle body is located between the two groups of baffles 2, and an electric conveying roller 3 is arranged in the middle of the conveyor belt 1, and both ends of the electric conveying roller 3 are rotatably connected with vertically arranged supporting legs 4, and the baffle 2 is fixedly connected to the supporting legs 4 through a bracket 5; a feeding structure is horizontally arranged above the conveyor belt 1, and a plurality of groups of vertically arranged conveying cylinders 6 are arranged below the feeding structure, and the conveying cylinders 6 are connected with the feeding structure, and the lower ends of the conveying cylinders 6 are rotatably connected with a clamping structure, and an assembling structure is arranged inside the clamping structure, and a driving structure is arranged on the outer side of the conveying cylinder 6, and the driving structure is used to drive the assembling structure to move downward.

[0028] When in use, the bottle body is conveyed by the conveyor belt 1, and the stability of the bottle body can be improved by cooperating with the baffle 2. When the bottle body moves to a certain position, the bottle body is located below the conveying cylinder 6. The feeding structure conveys a plurality of groups of screw caps into the conveying cylinder 6, and the conveying cylinder 6 stores the screw caps. At the same time, the screw caps located at the bottom of the conveying cylinder 6 are in contact with the clamping structure, and the stability of the screw caps is ensured by the clamping structure. At the same time, the driving structure drives the assembly structure to move downward, and the screw caps are driven downward when the assembly structure moves downward. After the screw caps move downward to a certain position, the screw caps are in contact with the bottle body, and the assembly structure rotates to drive the screw caps to rotate. When the screw caps rotate, they are rotated and tightened with the bottle body, thereby completing the screw cap assembly.

[0029] After a group of screw caps are assembled, the driving structure drives the assembly structure to reset and move upward. When the conveyor belt 1 transports the next group of bottles to the bottom of the conveying cylinder 6, the clamping structure, driving structure and assembly structure are used to assemble the next group of screw caps. There is no need for a robot to reciprocate to pick up the screw caps for assembly, thereby improving production efficiency and convenience.

[0030] It should be noted that the upper parts of the two groups of baffles 2 can be tilted inwards to improve the vertical stability of the bottles when they are transported on the conveyor belt 1 .

[0031] For example, Figure 1 , Figure 3 , Figure 7 As shown, the present invention also includes that the feeding structure includes a storage box 7, and the upper surface of the storage box 7 is provided with a plurality of feeding holes 8 connected with the conveying cylinder 6, and the feeding holes 8 are cone-shaped with a larger upper part and a smaller lower part, and both sides of the storage box 7 are fixedly connected with connecting rods 9, and the end of the connecting rod 9 away from the storage box 7 is fixedly connected with a vertically arranged supporting leg 10.

[0032] When in use, several groups of screw caps are respectively conveyed into several groups of feed holes 8, and after entering the feed holes 8, the screw caps fall into the conveying cylinder 6 and are stacked in the conveying cylinder 6, so as to facilitate the subsequent assembly of the screw caps and the bottle body. At the same time, the overall stability of the storage box 7 can be improved by relying on the function of the connecting rod 9 and the supporting legs 10;

[0033] It should be pointed out that when the screw cap of the present invention is conveyed into the feed hole 8, it is necessary to ensure that the end of the screw cap assembled with the bottle body faces downwards to facilitate subsequent assembly with the bottle body.

[0034] In order to ensure the stability of the screw cap, for example, Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes that the clamping structure includes a rotating ring 11, the upper surface of the rotating ring 11 is rotatably connected to the lower surface of the conveying cylinder 6, and the lower surface of the rotating ring 11 is fixedly connected with a plurality of groups of vertically arranged arc plates 12, and the arc plates 12 are distributed in an array around the rotating ring 11, and mounting grooves 13 are formed between adjacent arc plates 12, and a horizontally arranged support plate 14 is provided in the mounting groove 13, and the support plate 14 is located at the lower part of the mounting groove 13, and the support plate 14 is fixedly connected with a spring shaft 15, and the support plate 14 is hinged to the arc plate 12 through the spring shaft 15.

[0035] When in use, after the screw cap enters the conveying cylinder 6, the screw cap falls to the lower part of the rotating ring 11, and at the same time, several groups of support plates 14 are used to support the lower surface of the screw cap, so as to ensure the stability of the screw cap. When the screw cap needs to be assembled, the driving structure is used to drive the assembly structure to move downward, and the assembly structure is pressed and contacted with the outer side of the screw cap when it moves downward, so as to ensure the stability of the screw cap. At the same time, when the assembly structure moves downward, it squeezes the support plate 14 and drives the support plate 14 to swing downward, so as to facilitate the assembly structure to drive the screw cap to move downward. When the screw cap moves down to a certain position, the screw cap contacts the bottle body, and at the same time drives several groups of arc plates 12 to rotate, thereby completing the assembly of the screw cap and the bottle body.

[0036] After a group of screw caps are assembled, the driving structure drives the assembly structure to reset and move upward. At this time, the screw caps assembled with the bottle body will be separated from the driving structure, and the support plate 14 will be driven to reset and swing by the action of the spring shaft 15. When the support plate 14 returns to its initial state, the next group of screw caps falls on the top of several groups of support plates 14, so as to facilitate the assembly of the next group of screw caps and improve the convenience of screw cap assembly.

[0037] In order to improve the convenience of screw cap assembly, for example, Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the present invention also includes that the assembly structure includes a first guide groove installed on both sides of the arc plate 12, the first guide groove includes a first slide groove 16, a second slide groove 17, and a third slide groove 18 connected in sequence from top to bottom, the first slide groove 16 and the third slide groove 18 are vertically arranged, the second slide groove 17 is inclined to the inner side of the arc plate 12, and a sliding seat 19 is provided in the mounting groove 13. The sliding seat 19 is initially located in the first slide groove 16 and is slidably connected to the first slide groove 16, and the lower surface of the sliding seat 19 is fixedly connected to a vertically arranged extrusion rod 20. After the sliding seat 19 moves downward, the extrusion rod 20 is in extrusion contact with the upper surface of the support plate 14 and drives the support plate 14 to swing downward.

[0038] When in use, after the screw cap enters the conveying cylinder 6, the screw cap falls to the lower part of the rotating ring 11, and at the same time, several groups of support plates 14 are used to support the lower surface of the screw cap, so as to ensure the stability of the screw cap. When the screw cap needs to be assembled, the driving structure drives several groups of sliding seats 19 to move down. When the sliding seat 19 moves down to a certain position, the sliding seat 19 is slidably connected with the second slide groove 17. At this time, the second inclined slide groove 17 is used to make the sliding seat 19 squeeze and contact with the outer side of the screw cap, so as to ensure the stability of the screw cap. At the same time, as the sliding seat 19 moves down to a certain position in the second slide groove 17, the sliding seat 19 enters the third slide groove 18, and then the extrusion rod 20 under the sliding seat 19 squeezes and contacts with the upper surface of the support plate 14, and drives the support plate 14 to swing, so as to facilitate the sliding seat 19 to drive the screw cap to move down, so that the screw cap contacts the bottle body, which is convenient for the subsequent driving of the arc plate 12 to rotate, and the assembly of the screw cap is completed, so as to further improve the convenience of screw cap assembly.

[0039] After the screw cap assembly is completed, the driving structure drives the sliding seat 19 to reset and move upward. At this time, the screw cap assembled with the bottle body will be separated from the driving structure, and the next group of screw caps will fall on the upper part of the sliding seat 19, so as to prevent the next group of screw caps from directly passing through the driving structure; after the sliding seat 19 is reset and moved upward, the spring shaft 15 drives the support plate 14 to reset and move, and at the same time the sliding seat 19 and the support plate 14 return to their initial state, so as to facilitate the subsequent assembly of the next group of screw caps.

[0040] In order to facilitate the downward movement of the sliding seat 19, for example, Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the present invention also includes that the driving structure includes a driving ring 21, and the driving ring 21 is located on the outside of several groups of arc plates 12. The lower surface of the driving ring 21 is provided with a second guide groove 22 corresponding to the sliding seat 19, and a slider 23 is slidably connected in the second guide groove 22. The bottom of the slider 23 is fixedly connected to the sliding seat 19, and a vertically arranged electric hydraulic telescopic rod 24 is provided on the outside of the conveying cylinder 6. The output end of the electric hydraulic telescopic rod 24 is in sliding contact with the upper surface of the driving ring 21, and the fixed end of the electric hydraulic telescopic rod 24 is fixedly connected to the outside of the conveying cylinder 6 through a first connecting plate 25.

[0041] When in use, when the screw cap needs to be assembled, the electric hydraulic telescopic rod 24 drives the driving ring 21 to move downward, and when the driving ring 21 moves downward, the slider 23 drives the sliding seat 19 to move downward. When the sliding seat 19 moves downward, the sliding seat 19 slides from the first slide groove 16 into the second slide groove 17, and at the same time, the slider 23 moves toward the screw cap side in the second guide groove 22, so that the sliding seat 19 clamps the screw cap and drives the screw cap to move downward to correspond to the bottle body, and at the same time, it is convenient to drive the arc plate 12 to rotate subsequently to complete the assembly of the screw cap;

[0042] After the screw cap assembly is completed, the electric hydraulic telescopic rod 24 contracts to allow the drive ring 21 to reset and move upward. When the drive ring 21 resets and moves upward, the sliding seat 19 is driven to reset and move upward through the slider 23. While the slider 23 moves upward and resets, the slider 23 moves outward in the second guide groove 22, so as to facilitate the subsequent assembly of the next group of screw caps.

[0043] For example, Figure 3 , Figure 4 As shown, the present invention also includes that the outer sides of several groups of the arc plates 12 are fixedly connected with a horizontally arranged mounting plate 26, the upper surface of the mounting plate 26 is fixedly connected with a vertically arranged return spring 27, and the upper end of the return spring 27 is fixedly connected to the lower surface of the driving ring 21.

[0044] When in use, the electric hydraulic telescopic rod 24 squeezes the drive ring 21 to move downward, squeezing the return spring 27 to store force. When the cover is assembled, the electric hydraulic telescopic rod 24 contracts, relying on the return spring 27 to drive the drive ring 21 and the sliding seat 19 to reset, further improving the overall stability of use.

[0045] For example, Figure 3 , Figure 4 , Figure 6 , Figure 8 As shown, the present invention also includes that a driving motor 28 is provided on one side of the conveying cylinder 6, and the driving motor 28 is fixedly connected to the outer side of the conveying cylinder 6 through a second connecting plate 29. The output shaft of the driving motor 28 is fixedly connected with a gear 30, and a tooth structure 31 is provided on the outer side of the driving ring 21. After the driving ring 21 moves downward, the tooth structure 31 meshes with the gear 30 for transmission.

[0046] When in use, when the screw cap needs to be assembled, the electric hydraulic telescopic rod 24 drives the driving ring 21 to move downward, and when the driving ring 21 moves downward, the slider 23 drives the sliding seat 19 to move downward, and the sliding seat 19 moves downward to drive the screw cap to move downward and correspond to the bottle body at the same time. When the driving ring 21 moves down to a certain position, the tooth structure 31 on the outer side of the driving ring 21 meshes with the gear 30 for transmission, and the driving motor 28 drives the gear 30 to rotate, thereby driving the driving ring 21 to rotate. When the driving ring 21 rotates, the slider 23 and the sliding seat 19 drive several groups of arc plates 12 to rotate, and when the arc plates 12 rotate, the rotating ring 11 is driven to rotate, so as to facilitate the assembly of the screw cap;

[0047] After the cap is assembled, the electric hydraulic telescopic rod 24 contracts, and the reset spring 27 drives the drive ring 21 and the sliding seat 19 to reset. After the drive ring 21 is reset and moved upward, the tooth structure 31 no longer meshes with the gear 30 for transmission, thereby facilitating the subsequent assembly of the next group of caps, further improving the convenience of cap assembly.

[0048] For example, Figure 5 , Figure 6 As shown, the present invention further includes that a side of the sliding seat 19 away from the return spring 27 is detachably connected with an anti-skid pad 32 .

[0049] When in use, the detachably connected anti-skid pad 32 can improve the extrusion stability of the outer side of the twist cap, further ensuring the convenience of assembling the twist cap; it should be pointed out that the clamping force of the sliding seat 19 on the twist cap by the anti-skid pad 32 is relatively small, which is not enough to drive the twist cap assembled with the bottle body to move upward, thereby ensuring that after the assembly of the twist cap and the bottle body is completed, the driving structure moves upward and the twist cap can be separated from the driving structure; and vertical anti-skid stripes are provided on the outer side of the twist cap, so as to facilitate the driving structure to drive the twist cap to rotate.

[0050] When the present invention is in use, the conveyor belt 1 is used to convey the bottle body, and the baffle 2 can be used to improve the stability of the bottle body. When the bottle body moves to a certain position, the bottle body is located below the conveying cylinder 6, and a plurality of groups of screw caps are respectively conveyed to a plurality of groups of feed holes 8. After the screw caps enter the feed holes 8, they fall into the conveying cylinder 6 and are stacked in the conveying cylinder 6. After the screw caps enter the conveying cylinder 6, they fall to the lower part of the rotating ring 11, and at the same time, the lower surface of the screw caps is supported by a plurality of groups of support plates 14, so as to ensure the stability of the screw caps.

[0051] When the screw cap needs to be assembled, the electric hydraulic telescopic rod 24 drives the driving ring 21 to move downward. When the driving ring 21 moves downward, the slider 23 drives the sliding seat 19 to move downward. When the sliding seat 19 moves downward to a certain position, the sliding seat 19 is slidably connected with the second slide groove 17. At this time, the sliding seat 19 is squeezed and contacted with the outer side of the screw cap by relying on the inclined second slide groove 17, so as to ensure the stability of the screw cap. At the same time, as the sliding seat 19 moves downward to a certain position in the second slide groove 17, the sliding seat 19 enters the third slide groove 18, and then the extrusion rod 20 under the sliding seat 19 is squeezed and contacted with the upper surface of the support plate 14, and drives the support plate 14 to swing, so as to facilitate the sliding seat 19 to drive the screw cap to move downward, so that the screw cap contacts the bottle body;

[0052] When the driving ring 21 moves down to a certain position, the tooth structure 31 on the outer side of the driving ring 21 meshes with the gear 30 for transmission, and the driving motor 28 drives the gear 30 to rotate, thereby driving the driving ring 21 to rotate. When the driving ring 21 rotates, the slider 23 and the sliding seat 19 drive the plurality of arc plates 12 to rotate. When the arc plates 12 rotate, the rotating ring 11 is driven to rotate, so as to facilitate the assembly of the screw cap.

[0053] After the capping assembly is completed, the electric hydraulic telescopic rod 24 contracts, and the reset spring 27 drives the drive ring 21 and the sliding seat 19 to reset. After the drive ring 21 resets and moves upward, the tooth structure 31 no longer meshes with the gear 30 for transmission. After the sliding seat 19 resets and moves upward, the spring shaft 15 drives the support plate 14 to reset and move. At the same time, the sliding seat 19 and the support plate 14 return to their initial state, so as to facilitate the subsequent assembly of the next group of capping screws, further improving the convenience of capping screw assembly.
