Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, and in particular relates to a circulating ink supply device for a sticker printing machine. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding. Its working principle is to first make the text and images to be printed into a printing plate, install it on the printing press, and then directly or indirectly transfer it to other substrates, thereby replicating the same printed product as the printing plate.

[0003] In order to ensure the normal supply of ink when the printing press is printing, many printing presses on the market are equipped with an ink circulation continuous supply device. However, the ink circulation continuous supply device lacks an internal mechanism for moving the ink during use, and the ink components are prone to sedimentation, which in turn affects the printing quality. In addition, there is a lack of an early warning mechanism for the ink level during use, and no quick warning can be given when the ink is running out, which has certain limitations in use.

In addition, there is a lack of an early warning mechanism for the ink amount during use, and no quick warning can be given when the ink is running out, resulting in certain limitations in use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circulating ink supply device for a sticker printing machine, comprising a mounting frame, a plurality of mounting bolts are threadedly mounted on the mounting frame, a plurality of ink cartridges are fixed in the mounting frame, a same protective cover is rotatably mounted between the plurality of ink cartridges, an assembly plate 1 is fixedly mounted on the side of the ink cartridge at the edge position, an assembly plate 2 is fixedly mounted on the side of the protective cover, the assembly plate 1 and the assembly plate 2 are used in conjunction with each other, a rotating shaft is rotatably mounted on the upper surface of the ink cartridge, a motor is fixedly mounted on the upper surface of the protective cover, a plurality of shifting blades are fixedly mounted on the outer surface of the rotating shaft, an audible and visual alarm is fixedly mounted on the side of the mounting frame, a floating plate is slidably mounted inside the ink cartridge, a contact plate is fixedly mounted on the lower surface of the floating plate, a contact switch is fixedly mounted on the lower surface of the inner wall of the ink cartridge, the contact switch is located on the lower surface of the contact plate, the contact switch is electrically connected to the audible and visual alarm, an ink delivery tube is installed through the lower surface of the ink cartridge, an ink injection port is provided on the upper surface of the ink cartridge, and a sealing plug is inserted at the position of the ink injection port.

[0013] By adopting the above solution, the pulley and the belt are used in combination, so that the multiple shafts can rotate synchronously when the motor is working.

[0014] As a preferred implementation, a plurality of connecting plates are fixedly installed between the plurality of ink delivery tubes.

[0015] By adopting the above solution, the connection plate can be arranged to connect multiple ink delivery tubes, thereby ensuring a good connection effect.

[0016] As a preferred embodiment, a supporting shaft is fixedly mounted on the bottom end of the rotating shaft, and the supporting shaft is rotatably mounted on the inner wall of the ink cartridge.

[0017] By adopting the above scheme, the rotating shaft can be supported by the setting of the support shaft, so that the rotating shaft has good stability when rotating and is not prone to shaking.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The circular ink supply device of the sticker printing machine is used by setting a mounting frame to cooperate with a plurality of ink cartridges. The rotating shaft on the ink cartridge is used in cooperation with a paddle to paddle the ink in the ink cartridge, which can effectively prevent the ink components from being deposited, thereby ensuring the good quality of ink printing. The floating plate is used in cooperation with a resistance plate, a contact switch and an audible and visual alarm. When the ink is used, the floating plate floats at the ink level, and as the amount of ink decreases, the resistance plate is driven to move downward, and when the amount of ink is almost used up, the contact switch is touched, thereby driving the audible and visual alarm to give an early warning, thereby achieving the effect of early warning of the amount of ink.

[0020] The circulating ink supply device of the sticker printing machine is provided with a protective cover, and the motor, the pulley, the belt and the ink injection port can be isolated and protected by the protective cover, and the assembly plate 1 and the assembly plate 2 are used for locking, so the structure is simple and the operation is convenient.
