Description

Technical Field

[0001] The utility model relates to an external pasting machine. Background Art

[0002] In order to mark and decorate packaging bags, it is necessary to stick stickers and other items on the sides of the packaging bags. Usually, rolls of finished stickers are used, and the protective film needs to be manually torn off and then pasted on the sides of the packaging bags. In the prior art, these operations are mechanically complicated, especially the step of tearing off the protective film. Since the protective film needs to be separated from the sticker, it is impossible to use a rotary device to directly stick the stickers on each packaging bag in turn by rotating it, which hinders the speed of shipment and reduces production efficiency. As a result, production line equipment generally cannot automatically produce at high speed. Therefore, a sticker machine that can automatically tear off the protective film and expose the sticker is needed.

[0003] In view of the above reasons, how to automatically tear off the protective film and expose the sticker is exactly the problem considered in this application. Utility Model Content

[0004] In view of the shortcomings of the prior art, a sticker machine is provided, which can automatically tear off the protective film and expose the sticker.

[0005] To achieve the above-mentioned purpose, the following technical solution is provided: an external sticker machine, comprising a shell, a through hole for drawing out stickers is provided on the surface of the shell, an isolation plate is fixedly connected inside the shell, the isolation plate is rotatably connected to a first transmission shaft arranged away from the through hole, a second transmission shaft arranged close to the through hole, and a third transmission shaft arranged between the first transmission shaft and the second transmission shaft, a mounting wheel for placing rolled stickers is fixedly connected to the side of the first transmission shaft close to the through hole, a first roller for changing the extending direction of stickers is fixedly connected to the side of the second transmission shaft close to the through hole, and a roller for collecting stickers is fixedly connected to the side of the third transmission shaft close to the through hole. A first collecting wheel for the nano protective film, a first transmission shaft is fixedly connected to the first transmission wheel on the side away from the through-port, a fourth transmission shaft is also rotatably connected to the side of the isolation plate away from the through-port, the fourth transmission shaft is fixedly connected to the second transmission wheel and the third transmission wheel, the first transmission wheel is connected to a first transmission belt connected to the second transmission wheel, the second transmission shaft is fixedly connected to the fourth transmission wheel and the fifth transmission wheel on the side away from the through-port, the fourth transmission wheel is connected to the second transmission belt connected to the third transmission wheel, the third transmission shaft is fixedly connected to the sixth transmission wheel on the side away from the through-port, and the sixth transmission wheel is connected to the third transmission belt connected to the fifth transmission wheel.

[0006] In summary, the above technical solution has the following beneficial effects: usually, the side of the sticker printed with the pattern will be pasted on the connecting film with a certain viscosity, and the side coated with glue will contact the non-sticky protective film. When using the device, it is only necessary to pull out the connecting film, so that the side of the sticker coated with glue will be exposed, thereby facilitating pasting;

[0007] When in use, the rolled sticker is placed on the installation wheel, the connecting film from which the protective film has been peeled off is extended out of the through hole, and the protective film is connected to the first receiving wheel. When the connecting film is pulled, the installation wheel is first driven to rotate, thereby driving the first transmission wheel to rotate through the first transmission shaft, and then driving the first receiving wheel to rotate through the first transmission belt, the second transmission wheel, the fourth transmission shaft, the third transmission wheel, the second transmission belt, the fourth transmission wheel, the second transmission shaft, the fifth transmission wheel, the third transmission belt, the sixth transmission wheel and the third transmission shaft in sequence, so that the first receiving wheel peels off the protective film from the connecting film when rotating, and the pulled-out connecting film can be directly placed on the packaging bag on the sticker, thereby quickly realizing the external pasting operation;

[0008] The utility model peels off the protective film from the connecting film by the rotation of the first receiving wheel, thereby achieving the purpose of automatically tearing off the protective film and exposing the sticker. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figure 1-3 As shown, an external sticker machine includes a shell 1, a through hole 2 for drawing out stickers is provided on the surface of the shell 1, an isolation plate 3 is fixedly connected inside the shell 1, and the isolation plate 3 is rotatably connected to a first transmission shaft 4 arranged away from the through hole 2, a second transmission shaft 5 arranged close to the through hole 2, and a third transmission shaft 6 arranged between the first transmission shaft 4 and the second transmission shaft 5, a mounting wheel 41 for placing rolled stickers is fixedly connected to the side of the first transmission shaft 4 close to the through hole 2, a first roller 51 for changing the extending direction of stickers is fixedly connected to the side of the second transmission shaft 5 close to the through hole 2, and a first receiving wheel 61 for receiving protective film is fixedly connected to the side of the third transmission shaft 6 close to the through hole 2. A first transmission wheel 42 is fixedly connected to the side of the shaft 4 away from the through-port 2, a fourth transmission shaft 7 is also rotatably connected to the side of the isolation plate 3 away from the through-port 2, a second transmission wheel 71 and a third transmission wheel 72 are fixedly connected to the fourth transmission shaft 7, a first transmission belt 43 connected to the second transmission wheel 71 is connected to the first transmission wheel 42, a fourth transmission wheel 52 and a fifth transmission wheel 53 are fixedly connected to the side of the second transmission shaft 5 away from the through-port 2, the fourth transmission wheel 52 is connected to the second transmission belt 54 connected to the third transmission wheel 72, a sixth transmission wheel 62 is fixedly connected to the side of the third transmission shaft 6 away from the through-port 2, and the sixth transmission wheel 62 is connected to the third transmission belt 63 connected to the fifth transmission wheel 53;

[0022] Usually, the side of the sticker with the pattern printed on it will be pasted on a connection film with a certain degree of stickiness, while the side coated with glue will be in contact with a non-stick protective film. When using this device, you only need to pull out the connection film, so that the side of the sticker coated with glue will be exposed, making it easier to paste;

[0023] When in use, the rolled sticker is placed on the mounting wheel 41, the connecting film from which the protective film has been peeled off is extended out of the through hole 2, and the protective film is connected to the first receiving wheel 61. When the connecting film is pulled, the mounting wheel 41 is first driven to rotate, thereby driving the first transmission wheel 42 to rotate through the first transmission shaft 4, and then driving the first receiving wheel 61 to rotate through the first transmission belt 43, the second transmission wheel 71, the fourth transmission shaft 7, the third transmission wheel 72, the second transmission belt 54, the fourth transmission wheel 52, the second transmission shaft 5, the fifth transmission wheel 53, the third transmission belt 63, the sixth transmission wheel 62 and the third transmission shaft 6 in sequence, so that the first receiving wheel 61 peels off the protective film from the connecting film when rotating, and the pulled-out connecting film can be directly placed on the packaging bag on the sticker, thereby quickly realizing the external pasting operation;

[0024] The utility model peels off the protective film from the connecting film by the rotation of the first receiving wheel 61, thereby achieving the purpose of automatically tearing off the protective film and exposing the sticker.

[0025] Furthermore, the housing 1 is also rotatably connected to a first guide shaft 11 and a second guide shaft 12 provided at the through opening 2;

[0026] After the connecting film extends out from the through opening 2, it can be placed on the surface of the shell 1 for external pasting. However, the connecting film that is continuously pulled out will accumulate on the surface of the shell 1, which is very likely to affect the external pasting operation. Therefore, a first guide shaft 11 and a second guide shaft 12 are provided. During the external pasting operation, the sticker can be moved to the center of the first guide shaft 11 and the second guide shaft 12 for easy pasting, while the discarded connecting film enters the interior of the shell 1 through the second guide shaft 12 to prevent accumulation on the surface of the shell 1.

[0027] Furthermore, the isolation plate 3 is also rotatably connected to a fifth transmission shaft 8, and a second receiving wheel 81 for receiving the connection film is fixedly connected to the side of the fifth transmission shaft 8 close to the through opening 2;

[0028] The first receiving wheel 61 and the second receiving wheel 81 are respectively arranged on both sides of the through opening 2;

[0029] The second transmission shaft 5 is also fixedly connected to a seventh transmission wheel 55 on a side away from the through opening 2, the fifth transmission shaft 8 is fixedly connected to an eighth transmission wheel 82 on a side away from the through opening 2, and the seventh transmission wheel 55 is connected to a fourth transmission belt 83 connected to the eighth transmission wheel 82;

[0030] Since the waste connection film guided into the shell 1 may also affect the external laminating operation, a second receiving wheel 81 is provided to receive the waste connection film by rotating, and the first receiving wheel 61 and the second receiving wheel 81 are respectively provided on both sides of the through opening 2, so that the separation of the connection film and the protective film can be facilitated;

[0031] In addition, when the mounting wheel 41 rotates, the second storage wheel 81 can also be driven to rotate in sequence through the second transmission shaft 5, the seventh transmission wheel 55, the fourth transmission belt 83, the eighth transmission wheel 82 and the fifth transmission shaft 8, thereby preventing the situation where the discarded connecting film cannot be stored in time.

[0032] Furthermore, a tensioner 9 is further provided in the housing 1, and the tensioner 9 includes a second roller 91 abutted by a protective film, the second roller 91 is rotatably connected to a connecting shaft 92, the connecting shaft 92 is fixedly connected to a positioning member 93, the positioning member 93 is fixedly connected to a positioning rod 94, the positioning rod 94 is slidably connected to a base 95 fixedly connected to the housing 1, and the positioning member 93 is fixedly connected to a spring 96 fixedly connected to the base 95;

[0033] The tensioner 9 mainly maintains the tautness of the protective film and the connecting film through the spring 96, so it is necessary to reduce the friction between the protective film and the connecting film and the connecting shaft 92 as much as possible. Since the contact surface is the protective film, the second roller 91 is set to reduce the friction on the protective film by rolling, and the spring 96 itself can provide a buffer for the connecting shaft 92, and the positioning rod 94 can slide in the base 95, so as to slightly change the extension direction of the protective film and the connecting film so that the protective film and the connecting film will not be too loose or too tight when moving. In addition, the positioning rod 94 can ensure that the second roller 91 can rotate while maintaining the overall structure of the tensioner 9 from falling apart.

[0034] Furthermore, a motor 13 connected to the fourth transmission shaft 7 is fixedly connected in the housing 1;

[0035] In addition to manual control, the entire transmission system can also be controlled by the motor 13, and the first storage wheel 61 and the second storage wheel 81 can both rotate automatically, so that the protective film and the connecting film can be automatically separated, thereby achieving the purpose of automatically tearing off the protective film and exposing the sticker.

[0036] Furthermore, a partition plate 14 for sealing the interior is fixedly connected to the shell 1 .

[0037] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
