DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] The present application embodiment discloses a hot stamping device for packaging bottles, referring to Figure 1 , including a frame 1 and a conveying device 2 arranged on the frame 1, and a loading device 3, a dust removal device 4, a hot stamping device 5 and a cleaning device 6 are sequentially arranged along the conveying direction of the conveying device 2. The loading device 3 first places the packaging bottles 11 individually on the conveying device 2. When the packaging bottles 11 move along the conveying device 2, the packaging bottles 11 are first cleaned of dust on the surface at the position of the dust removal device 4, and then reach the position of the hot stamping device 5 for hot stamping, and then the excess material generated by the hot stamping is cleaned by the cleaning device 6.

[0040] refer to Figure 2The loading device 3 includes a chute 31 and a suction assembly 32. The chute 31 can be configured in a U-shaped structure, allowing multiple bottles 11 to be sequentially loaded along its length. One end of the chute 31 is located at the initial position of the conveyor 2. A sensor 33 is located within the chute 31 at the end of the chute 31 proximal to the conveyor 2. Sensor 33 is configured to detect the position of the bottle 11. When the bottle 11 abuts the sensor 33, the bottle 11 is aligned with the initial position of the conveyor 2. The suction assembly 32 can be a robotic arm. In this embodiment, the suction assembly 32 is a pneumatic cylinder with a suction cup at its end. The cylinder is vertically mounted, and its upper end is slidably connected to the frame 1. When the cylinder moves directly above the chute 31, it drives the suction cup downward, which then picks up the bottle 11. The cylinder then moves to the initial position of the conveyor 2, where its downward movement places the bottle 11 onto the conveyor 2.

[0041] refer to Figure 3 The conveying device 2 includes a stepped conveying assembly 21 and a hot stamping conveying assembly 22. The stepped conveying assembly 21 includes an inner support frame 211 and an outer support frame 212. The inner support frame 211 includes two support plates 2111. The two support plates 2111 are arranged parallel and vertically, and the length direction of the support plates 2111 is the conveying direction of the stepped conveying assembly 21. A plurality of placement grooves 2112 are defined along the upper edges of the support plates 2111 and along their lengths. The placement grooves 2112 are V-shaped. The two support plates 2111 are fixedly arranged relative to each other, and the placement grooves 2112 on the two support plates 2111 are arranged relative to each other, so that the two placement grooves 2112 are used to support two parts of a packaging bottle 11, so that the packaging bottle 11 can be arranged on the conveying device 2 horizontally and perpendicular to the conveying direction of the conveying device 2. The outer support frame 212 includes a first positioning plate 2121 and a second positioning plate 2122. A positioning groove 2123 is provided on the first positioning plate 2121. A clamping cylinder 2124 is provided on the second positioning plate 2122 at a position opposite to the positioning groove 2123. The clamping cylinder 2124 is fixedly installed on the second positioning plate 2122, and a rotating wheel 2125 is rotatably installed on the output end of the clamping cylinder 2124. The center line of the rotating wheel 2125 coincides with the center of the positioning groove 2123. When the packaging bottle 11 is placed between the positioning groove 2123 and the pressing cylinder 2124, one end of the pressing cylinder 2124 can abut against the end of the packaging bottle 11, so that the bottom of the packaging bottle 11 enters the positioning groove 2123, so that the position of the packaging bottle 11 is relatively accurately located at the corresponding position of the positioning groove 2123. At the same time, the depth of the positioning groove 2123 is 1-2 mm. When the pressing cylinder 2124 is released, the packaging bottle 11 can automatically fall off from the positioning groove 2123.

[0042] refer to Figure 4Two step conveying assemblies 21 are provided, and the two step conveying assemblies 21 are arranged one after the other along the same conveying direction, so that the hot stamping conveying assembly 22 is located between the two step conveying assemblies 21. The inner support frame 211 of the step conveying assembly 21 located at the front end of the conveying device 2 is fixed to the frame 1, and the outer support frame 212 of the step conveying assembly 21 near the end of the conveying device 2 is fixed to the frame 1; the frame 1 is connected to a synchronous drive device 7, which is in transmission connection with the outer support frame 212 of the step conveying assembly 21 near the front end of the conveying device 2, and is also in transmission connection with the inner support frame 211 of the step conveying assembly 21 near the end of the conveying device 2, so that the synchronous drive device 7 can synchronize the beats of the two tread conveying assemblies.

[0043] refer to Figure 1 In the stepping conveyor assembly 21, when the inner support frame 211 is fixed, the outer support frame 212 is connected to the first drive shaft 23 and the first crank 231. The first drive shaft 23 is rotatably connected to the frame 1. One end of the first crank 231 is fixed on the first drive shaft 23, and the other end of the first crank 231 is rotatably connected to the outer support frame 212. At least two first drive shafts 23 are set, and the two first drive shafts 23 rotate synchronously, so that the outer support frame 212 can be kept in a horizontal state and move under the action of the first drive shaft 23. When the packaging bottle 11 is conveyed to the end of the conveying device 2, the packaging bottle 11 is first placed on the inner support frame 211, and then the outer support frame 212 drives the clamping cylinder 2124 and the positioning groove 2123 to correspond to the corresponding packaging bottle 11, and after clamping the packaging bottle 11, the outer support frame 212 is rotated upward by the first drive shaft 23 and the first crank 231, so that the packaging bottle 11 is removed from the placement groove 2112 of the inner support frame 211 and conveyed one step in the conveying direction of the conveying device 2. At the same time, the last packaging bottle 11 approaches the hot stamping conveying assembly 22 and is conveyed by the hot stamping conveying assembly 22, and then the clamping cylinder 2124 is released, so that the packaging bottle 11 falls on the inner support frame 211, and then the reaction rotation of the first drive shaft 23 makes the outer support frame 212 return to the position of conveying the packaging bottle 11 again.

[0044] refer to Figure 1In the stepping conveying assembly 21, when the outer support frame 212 is fixed to the frame 1, the inner support frame 211 is connected to the second drive shaft 24 and the second crank 241. The second drive shaft 24 is parallel to the first drive shaft 23 and is connected to the same synchronous drive device 7. At least two second drive shafts 24 are provided and are rotatably connected to the frame 1. One end of the second crank 241 is fixed to the second drive shaft 24, and the other end is rotatably connected to the inner support frame 21. When the stepping conveying assembly 21 close to the front end of the conveying device 2 conveys the packaging bottle 11 in the conveying direction of the conveying device 2, the stepping conveying assembly 21 close to the front end of the conveying device 2 conveys the packaging bottle 11 in the conveying direction of the conveying device 2. The packaging bottles 11 are fixed on the outer support frame 212 in the step conveying assembly 21 at the rear end of the device 2, and the inner support frame 211 rotates downward under the action of the second drive shaft 24 and the second crank 241 and moves toward the front end of the conveying device 2, for receiving the packaging bottles 11 delivered by the hot stamping conveying assembly 22. When the packaging bottles 11 delivered by the hot stamping conveying assembly 22 arrive at the step conveying assembly 21, the outer support frame 212 simultaneously places multiple packaging bottles 11 on the inner support frame 211, and the inner support frame 211 moves along the conveying direction of the conveying device 2 to move multiple packaging bottles 11 toward the conveying direction of the conveying device 2.

[0045] refer to Figure 4 The synchronous drive device 7 includes a drive motor 71, a slide bar 72, a drive gear 73, and a drive rack 74. The slide bar 72 is arranged horizontally and perpendicular to the first drive shaft 23 and is located below the first drive shaft 23 and the second drive shaft 24, so that the slide bar 72 is offset from the first drive shaft 23 and the second drive shaft 24. The drive motor 71 is fixed to the frame 1. A turntable 75 is coaxially fixed to the output shaft of the drive motor 71. The turntable 75 is connected to a connecting rod 76. One end of the connecting rod 76 is rotatably connected to the edge of the turntable 75, and the other end is rotatably connected to the slide bar 72. When the drive motor 71 rotates, the slide bar 72 reciprocates. A driving gear 73 is provided on each of the first driving shaft 23 and the second driving shaft 24, and each driving gear 73 corresponds to a driving rack 74. The driving rack 74 is fixed on the slide bar 72, and the length direction of the driving rack 74 is parallel to the length direction of the slide bar 72. The driving gear 73 is engaged with the driving rack 74. Since the angle of rotation of each step of the first driving shaft 23 and the second driving shaft 24 is different, the driving gear 73 needs to select a suitable radius according to the rotation angle of the first driving shaft 23 and the second driving shaft 24. Then, when different driving racks 74 move the same distance under the action of the same slide bar 72, the first driving shaft 23 and the second driving shaft 24 can keep the pace consistent, that is, return at the same time, and can accurately control each step of movement of the packaging bottle 11.

[0046] refer to Figure 5The hot stamping conveying assembly 22 includes a first rotating shaft 221 and a second rotating shaft 222. Both the first rotating shaft 221 and the second rotating shaft 222 are rotatably connected to the frame 1 and connected to the synchronous drive device 7, so that the synchronous drive device 7 can drive the first rotating shaft 221 and the second rotating shaft 222. Two swing arms 224 are connected to the first rotating shaft 221. The angle between the two swing arms 224 is 70-80 degrees. The intersecting ends of the two swing arms 224 are fixed to the first rotating shaft 221, and the other ends are each mounted with a bracket 223. The bracket 223 is used to place the packaging bottle 11. The bracket 223 is rotatably connected to the swing arm 224. The bracket 223 is also mounted with an anti-fall device 8. The anti-fall device 8 keeps the side of the bracket 223 on which the packaging bottle 11 is placed facing upward. When in use, one swing arm 224 swings between the vertical position and the step conveying assembly 21 at the front end of the conveying device 2, and the other swing arm 224 swings from the vertical position to the step conveying assembly 21 at the rear end of the conveying device 2; when the swing arm 224 is in the vertical position, the position of the frame 1 corresponding to the bracket 223 is the hot stamping position, and the hot stamping position is fixedly provided with a clamping cylinder 225 and a rotating disk 226. The end of the clamping cylinder 225 is also rotatably provided with a rotating wheel 2125, and the rotating wheel 2125 is coaxially arranged with the corresponding rotating disk 226. The clamping cylinder 225 and the pressing cylinder 2124 act synchronously. When the clamping cylinder 225 and the rotating disk 226 cooperate to clamp the packaging bottle 11, the position of the packaging bottle 11 is the position where the hot stamping device 5 can perform hot stamping on the packaging bottle 11, and the packaging bottle 11 is placed during the operation of the hot stamping device 5 so that the hot stamping sticks to the surrounding wall of the packaging bottle 11. During the hot stamping process of the hot stamping device 5, the swing arm 224 in the vertical position rotates driven by the first rotating shaft 221 and continues to convey the next packaged bottle 11, while the swing arm 224 located near the end of the conveyor device 2 rotates to the vertical position to remove the hot stamped packaged bottle 11 from the hot stamping position. A mounting arm 227 is fixedly mounted on the second rotating shaft 222. A clamping cylinder 225 and a rotating disk 226 are also fixedly mounted on the mounting arm 227. The clamping cylinder 225 on the mounting arm 227 operates synchronously with the clamping cylinder 225 located at the hot stamping position. After the clamping cylinder 225 and the rotating disk 226 on the mounting arm 227 clamp the packaged bottle 11, the second rotating shaft 222 is used to remove the package tray from the bracket 223 and rotate it upward to the step conveyor assembly 21 near the end of the conveyor device 2.

[0047] refer to Figure 4Rotating shaft 1 221 is also connected to slide bar 72 via a drive gear 73, a drive rack 74, and the radius of the corresponding drive gear 73 is adjusted according to the required rotation angle of rotating shaft 1 221. Drive gear 73 is coaxially fixed to rotating shaft 1 221, and drive rack 74 is fixed to slide bar 72. A synchronous gear 228 is provided on rotating shaft 2 222, and a synchronous gear 228 is also coaxially provided on a second drive shaft 24. A synchronous belt 229 is provided between the two synchronous gears 228. Rotating shaft 2 222 is driven by synchronous drive device 7 via synchronous belt 229, thereby ensuring that rotating shaft 1 221, rotating shaft 2 222, and the first drive shaft 23 and second drive shaft 24 move in synchronization.

[0048] refer to Figure 5 The anti-fall device 8 includes a vertical rod 81, a slider 82 and a slide 83. The slide 83 is arranged horizontally, and a slide groove 84 is opened on the slide 83. The slide groove 84 is arranged horizontally, and the slide 82 is slidably fitted in the slide groove 84. The vertical rod 81 vertically passes through the slider 82 and is slidably connected to the slider 82. The vertical rod 81 is a hollow structure. The lower end of the vertical rod 81 can be connected to the exhaust equipment. The upper end of the vertical rod 81 is exposed from the bracket 223, so that after the packaging bottle 11 is placed on the bracket 223, the vertical rod 81 can stick the packaging bottle 11 to the bracket 223 under the action of the exhaust equipment, further reducing the packaging bottle 11 from falling off the bracket 223. At the same time, during the movement of the swing arm 224, the slider 82 can slide horizontally along the slide groove 84, and the vertical rod 81 slides vertically relative to the slider 82, maintaining the orientation of the bracket 223, reducing the falling of the packaging bottle 11 during the movement, and on the other hand reducing extrusion or friction during the hot stamping of the outer surface of the packaging bottle 11, thereby improving the quality of the hot stamping.

[0049] refer to Figure 1 and Figure 3 The dust removal device 4 includes a blowing pipe 41, which is connected to a blowing device. An active disk 42 is provided at the bottom of a packaging bottle 11 corresponding to the air outlet of the blowing pipe 41.
