Description

Technical Field

[0001] The present invention relates to the technical field of capping machines, and in particular to a capping device capable of improving assembly efficiency. Background Art

[0002] In order to unify the bottle mouth size and save mold opening costs, manufacturers combine multiple components such as the upper cover, lower barrel, inner cover, connected barrel and inner plug assembly. The inner plug assembly corresponds to the bottle mouth size. The upper cover and lower barrel can be replaced according to the different external dimensions of the bottle cap, reducing mold opening costs and lowering processing costs. For example, Chinese patent CN215795610U discloses a weight-reducing plastic anti-counterfeiting bottle cap, including an upper cover, an inner cover, a connected barrel, an inner plug and a lower barrel. The upper cover wall is hollow, and the anti-rotation rib A on the lower barrel cooperates with the anti-rotation rib B on the connected barrel. The anti-rotation rib A extends downward, and the inner diameter A of the rib on the lower barrel cooperates with the outer diameter surface A of the connected barrel. The inner diameter B of the rib above the barb on the lower barrel cooperates with the outer diameter surface B of the connected barrel. The inner cap and the one-piece barrel are connected by threads. Currently, manual screw assembly is the most common method. This is not only inefficient and labor-intensive, but also difficult to control during assembly. Excessive torque often results in product scrap, leading to low production efficiency and high costs.

[0032] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] like Figures 1 to 15 As shown, the present invention discloses a twisting cover device for improving assembly efficiency, including a vertical pole 1, a top plate 2 and a frame platform 30, wherein the vertical pole 1 is provided with a plurality of vertical poles 1, a plurality of the vertical poles 1 are mounted on the frame platform 30, and the top plate 2 is mounted on the vertical pole 1. The present invention also includes a driving device, a main shaft 4, an upper positioning plate 45 and a plurality of groups of twisting cover mechanisms, wherein the upper end of the main shaft 4 is rotatably connected to the top plate 2, and the lower end passes through the frame platform 30 and is connected to the driving device, and rotates under the drive of the driving device, the main shaft 4 is mounted on the frame platform 30 through a second fixing sleeve 29, and the plurality of groups of twisting cover mechanisms are arranged circumferentially along the main shaft 4 and rotate around the main shaft 4. The cover twisting mechanism includes a corresponding transmission cover twisting assembly and a lower cover transmission mechanism. The upper positioning plate 45 is installed on the main shaft 4 through the flange 2 44. The transmission cover twisting assembly is located above the upper positioning plate 45. The lower cover transmission mechanism is arranged below the upper positioning plate 45. The upper positioning plate 45 is provided with a plurality of positioning holes for accommodating the cover body. The transmission cover twisting assembly includes a clamping tool for clamping the upper cover body 56. The transmission cover twisting assembly is used to drive the upper cover body 56 to rotate and move up and down. The lower cover transmission mechanism is used to drive the lower cover body 57 to move upward and make the lower cover body 57 cooperate with the upper cover body 56.

[0034] The twist cover device also includes an upper cam 3 and a chain 48 installed on the top plate 2. The chain 48 is connected to the fixed shaft 46. The fixed shaft 46 is installed on the top plate 2. The lower end of the fixed shaft 46 is installed with a fixed block three 47. The transmission twist cover assembly includes a torsion bar 5 and a transmission rod 7 arranged in parallel. The torsion bar 5 and the transmission rod 7 are respectively slidably installed on the upper guide plate 6 and the lower guide plate 11 through the positioning sleeve 12. The upper guide plate 6 and the lower guide plate 11 are installed on the main shaft 4 to increase the stability of the installation of the torsion bar 5 and the transmission rod 7. The upper end of the transmission rod 7 is connected to the upper cam 3 through a roller 13. A sprocket 14 is provided on the torsion bar 5. The transmission rod 7 is located on the inner side of the torsion bar 5, which facilitates the transmission connection between the torsion bar 5 and the chain 48 through the sprocket 14. The clamping tool is installed on the torsion bar 5.

[0035] It should be noted that a shift fork 9 is installed on the transmission rod 7, and a positioning block 8 and a guide sleeve 10 are installed on the torsion bar 5. The guide sleeve 10 is connected to the shift fork 9. When the main shaft 4 rotates, the upper guide plate 6 and the lower guide plate 11 drive the torsion bar 5 and the transmission rod 7 to rotate around the main shaft 4. At the same time, the transmission rod 7 moves up and down under the action of the upper cam 3, thereby driving the torsion bar 5 and the clamping tooling to move up and down; at the same time, the torsion bar 5 rotates around itself under the action of the sprocket 14 and the chain 48, thereby driving the clamping tooling to rotate, so that the upper cover body 56 and the lower cover body 57 are screwed together to complete the assembly.

[0036] In this embodiment, the cap-twisting mechanism is provided with 12 groups, which can assemble 12 pairs of bottle caps at the same time and produce about 120 bottle caps per minute, which greatly improves the assembly efficiency and ensures the assembly quality.

[0037] The twisting cover device also includes a lower cam 37, a lower positioning plate 40, a fixing rod 42 and a platform 43. The lower cam 37 is installed on the frame platform 30. The lower cover transmission mechanism includes a second roller 38 and a lower mold rod 39. The lower mold rod 39 is installed on the lower positioning plate 40 through a second guide sleeve 41. The lower positioning plate 40 is connected to the platform 43 through the fixing rod 42. The platform 43 is installed on the main shaft 4 through a second flange 44. The upper positioning plate 45 is connected to the platform 43. The platform 43 is provided with a through hole for accommodating the lower mold rod 39. The upper end of the lower mold rod 39 is used to lift the lower cover body 57 upward. The lower end of the lower mold rod 39 is connected to the second roller 38, and the second roller 38 is transmission-connected to the lower cam 37.

[0038] It should be noted that when the main shaft 4 rotates, it drives the platform 43 to rotate, and the platform 43 drives the lower positioning plate 40 to rotate through the fixed rod 42, thereby driving the roller 2 38 and the lower mold rod 39 to rotate around the main shaft 4. Since the roller 2 38 is connected to the lower cam 37 by transmission, the lower mold rod 39 moves up and down under the action of the lower cam 37, thereby lifting the lower cover body 57 and ensuring the normal assembly of the upper cover body 56 and the lower cover body 57.

[0039] like Figure 1 and Figure 5As shown, the clamping tooling includes a clutch upper part 15, a steel ball 16, a clutch lower part 17 and a twist cover upper tooling 20. The clutch upper part 15 is installed on the torsion bar 5. The clutch upper part 15 is provided with a mounting rod, and the clutch lower part 17 is provided with a mounting groove. The mounting rod is rotatably connected to the mounting groove through a bearing, and a nut is provided at the end of the mounting rod. The clutch upper part 15 is connected to the clutch lower part 17, and the steel ball 16 is rotatably arranged between the clutch upper part 15 and the clutch lower part 17. The twist cover upper tooling 20 is detachably mounted on the clutch lower part 17 through a flange 18. Different sizes of twist cover upper tooling 20 can be replaced according to different sizes of cover bodies, thereby improving the convenience and versatility of use and reducing processing costs.

[0040] It should be noted that when the torsion bar 5 rotates under the action of the chain 48, it drives the upper clutch part 15, the lower clutch part 17 and the twist cover upper tooling 20 to rotate synchronously, thereby realizing the assembly of the upper cover body 56 and the lower cover body 57. When the torque is too large, the upper clutch part 15 and the lower clutch part 17 will slide relative to each other under the action of the steel ball 16, avoiding the situation where the upper cover body 56 and the lower cover body 57 are torqued too tight, resulting in waste, ensuring product quality and reducing the waste rate.

[0041] The clamping tool also includes an adjusting block 52, a spring 53 and a fixing block 54 arranged in the upper part 15 of the clutch. The spring 53 is arranged between the adjusting block 52 and the fixing block 54. The end of the fixing block 54 is provided with an arc groove for accommodating the steel ball 16. The clutch lower part 17 is provided with a accommodating hole 55, and the steel ball 16 is arranged on the accommodating hole 55.

[0042] It should be noted that by adjusting the installation depth of the adjustment block 52 in the upper part 15 of the clutch, the preload force of the spring 53 is adjusted, and the pressing force of the steel ball 16 installed on the receiving hole 55 is adjusted, thereby adjusting the torque of the upper cover body 56 to ensure the normal assembly of the upper cover body 56 and the lower cover body 57, and meet the requirements of different screwing forces of different types of bottle caps.

[0043] In an optional embodiment, the clamping fixture further includes a discharge tray 19, the discharge tray 19 is mounted on the twist cover upper fixture 20, a discharge stopper 62 is provided on one side of the discharge tray 19, the discharge stopper 62 is mounted on the lower guide plate 11 through a connecting rod 63, a through hole is provided in the twist cover upper fixture 20, a discharge column 64 is provided in the through hole, a long slot extending along the length direction of the twist cover upper fixture 20 is provided on the side wall of the twist cover upper fixture 20, a pin passes through the long slot to connect the discharge tray 19 with the discharge column 64, and the twist cover upper fixture A boss is provided at the end of the device 20, and an elastic member is provided between the discharge tray 19 and the boss. In this embodiment, the elastic member is a compression spring, which maintains the discharge tray 19 and the discharge column 64 in a certain position to ensure that the upper cover body 56 is normally installed in the twist cover upper tooling 20. A plurality of anti-rotation edges are provided on the outer circumference of the upper cover body 56, and a mounting hole is provided at the lower end of the twist cover upper tooling 20. A plurality of anti-rotation teeth are provided on the inner wall of the mounting hole. The anti-rotation edges cooperate with the anti-rotation teeth to prevent the upper cover body 56 and the twist cover upper tooling 20 from rotating relative to each other. When the torsion bar 5 and the upper tooling 20 of the twist cover move downward under the action of the upper cam 3, the upper cover body 56 is pressed into the upper tooling 20 of the twist cover, and rotates under the action of the chain 48 and the sprocket 14, and the upper cover body 56 is rotatably installed on the lower cover body 57. After the upper cover body 56 and the lower cover body 57 are assembled, when the upper tooling 20 of the twist cover moves upward, the unloading stopper 62 overcomes the spring force and pushes the unloading plate 19 and the unloading column 64 downward, thereby removing the cover body in the upper tooling 20 of the twist cover to facilitate the next assembly.

[0044] The drive device includes a large gear 32, a drive gear 33, and a motor 34. The large gear 32 is mounted on the main shaft 4 at the lower end of the frame platform 30. The large gear 32 meshes with the drive gear 33. The drive gear 33 is mounted on a drive shaft 35 of the motor 34. The drive shaft 35 is mounted on the frame platform 30 via a flange 36. When the motor 34 rotates, the drive gear 33 is driven to rotate via the drive shaft 35. The large gear 32 meshes with the drive gear 33, thereby driving the main shaft 4 to rotate.

[0045] The capping device further includes a bottle cap conveying mechanism, which includes an upper cap conveying mechanism and a lower cap conveying mechanism. The lower cap conveying mechanism includes a fixed block 21, a rotary disk 22, a fixed sleeve 23, a rotating shaft 24, a gear 31.1 and a support plate 60. The rotating shaft 24 is mounted on the frame platform 30 through the fixed sleeve 23. The upper end of the rotating shaft 24 is provided with the rotary disk 22 and a support plate 60. The rotary disk 22 is mounted on the support plate 60 through the fixed block 21. The outer edge of the rotary disk 22 is provided with a card slot for accommodating the lower cover body 57. The lower end of the rotating shaft 24 passes through the frame platform 30 and is connected to the gear 31.1. The gear 1 31.1 is engaged with the large gear 32; the upper cover conveying mechanism includes a fixed block 25, a turntable 26, a fixed sleeve 1 27, a rotating shaft 28, a gear 2 31.2 and a support plate 2 61. The rotating shaft 28 is installed on the frame platform 30 through the fixed sleeve 1 27. The upper end of the rotating shaft 28 is provided with a turntable 26 and a support plate 2 61. The turntable 26 is installed on the support plate 2 61 through the fixed block 25. The outer edge of the turntable 26 is provided with a card slot 2 for accommodating the upper cover body. The lower end of the rotating shaft 28 passes through the frame platform 30 and is connected to the gear 2 31.2. The gear 2 31.2 is engaged with the large gear 32.

[0046] In an optional embodiment, the twisting cover device also includes two groups of lifting components, one group of lifting components corresponds to the upper cover conveying mechanism, and the other group of lifting components corresponds to the lower cover conveying mechanism. Each group of the lifting components includes a slide 49, a sorter 50 and an elevator 51. The elevator 51 conveys the upper cover body 56 and the lower cover body 57 to the slide 49 through the sorter 50. One of the slides 49 conveys the lower cover body 57 to the turntable 1 22, and the other slide 49 conveys the upper cover body 56 to the turntable 2 26, thereby realizing automatic conveying of the upper cover body 56 and the lower cover body 57, further improving assembly efficiency.

[0047] It should be noted that turntable 1 22 and upper positioning plate 45 are located at the same height, with turntable 1 22 being shorter than turntable 2 26. Gear 1 31.1 and gear 2 31.2 are identical in size and both mesh with large gear 32, driven by large gear 32. Large gear 32 has twice the number of teeth as gears 31.1 and 31.2. Therefore, for every rotation of upper positioning plate 45, both turntable 1 22 and turntable 2 26 rotate twice.

[0048] The working process of the present invention is as follows:

[0049] The lower cover 57 enters the slot 1 of the rotary disk 1 22 through a slide 49. The rotary disk 1 22 is driven to rotate by the gear 1 31.1. The outer edge of the slot 1 is provided with an arc-shaped baffle 1 58. The arc-shaped baffle 1 58 ensures that the lower cover 57 is stably placed in the slot 1 and ensures that the lower cover 57 in the slot 1 is transported to the positioning hole of the upper positioning disk 45. When the positioning hole of the upper positioning disk 45 fits with the slot 1, the lower cover 57 in the slot 1 moves into the positioning hole of the upper positioning disk 45. The lower cover 57 and the upper positioning disk 45 continue to rotate driven by the large gear 32.

[0050] The upper positioning plate 45 is located below the support plate 61. The projection of the second card slot and the positioning hole on the horizontal plane forms a circle. The support plate 61 is provided with a second arc baffle 59. The arc baffle 59 ensures that the upper cover 56 is stably placed in the second card slot. When the torsion bar 5 rotates to the b position of the upper cam 3, see Figure 14 As shown, corresponding to Figure 2 When the torsion bar 5 is at position B in the figure, the torsion bar 5 continues to move from position B to position C. The torsion bar 5 moves downward under the action of the upper cam 3, pressing the upper cover 56 into the upper tooling 20 of the torsion cover. When the torsion bar 5 is at position C of the upper cam 3, the torsion bar 5 corresponds to Figure 2 At point C in the figure, the torsion bar 5 starts to rotate under the action of the sprocket 14 and the chain 48. At the same time, the lower die rod 39 moves upward under the action of the lower cam 37. The upper end of the lower die rod 39 is movably installed with a top block 65, which is convenient for the top block 65 to cooperate with the lower cover 57. The top block 65 pushes the lower cover 57 upward. The inner circumference of the lower cover 57 is provided with a plurality of anti-rotation teeth, and the outer circumference of the top block 65 is provided with a plurality of anti-rotation teeth. The anti-rotation teeth cooperate with the anti-rotation ridges to prevent the lower cover 57 and the top block 65 from rotating relative to each other. Under the rotation of the torsion bar 5 and the tooling 20 on the torsion cover The upper cover 56 and the lower cover 57 are rotated and assembled together. When the torsion bar 5 rotates a sufficient number of times, the sprocket 14 and the chain 48 are gradually separated. After the assembly is completed, when the torsion bar 5 moves from d to e, the torsion bar 5, the upper tooling 20 of the twist cover and the assembled cover body move upward, and the unloading block 62 overcomes the elastic force of the compression spring to prevent the unloading tray 19 and the unloading column 64 from moving upward, so that the unloading tray 19 and the upper tooling 20 of the twist cover move relative to each other, and the unloading tray 19 drives the unloading column 64 to remove the assembled cover body in the upper tooling 20 of the twist cover, completing one assembly.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
