Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a transfer plate cleaning device. Background Art

[0002] At present, the surface printing process of daily-use ceramics, such as cups and bowls, generally adopts pad printing process. The pad printing process requires setting a pattern of a certain depth on the substrate to make a concave plate, and then filling the pattern with ink. Using a curved pad printing head made of silicone rubber material, the ink on the concave plate is dipped onto the surface of the pad printing head. The pad printing head applies pressure to the surface of the required object to print the pattern or text on the curved surface.

[0003] However, during the pattern transfer process, neither the ink on the plate surface nor the ink on the silicone head can be completely transferred to the substrate. After each transfer, a very small amount of ink will remain on the transfer plate and the silicone. In order to avoid the accumulation of residual ink, which will affect the color difference of the pattern, or interfere with the new pattern and reduce the product quality, it is necessary to clean the plate surface and the silicone surface after a certain number of transfers or when changing the pattern to remove the residual ink.

[0004] However, when cleaning the surface of the transfer plate, manual cleaning is time-consuming and labor-intensive, and the degree of automation is low. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, this embodiment provides a transfer plate cleaning device, including: a carrying platform 1, a cleaning base 2 and a driving unit.

[0025] The top of the carrying platform 1 is in a flat plate shape and is suitable for carrying the transfer plate 3. When the transfer plate 3 is placed on the carrying platform 1, the side to be cleaned faces away from the carrying platform 1 and is set upward for easy cleaning.

[0026] The cleaning base 2 is movably connected with a liquid supply structure and a cleaning body 26. In the present embodiment, the cleaning base 2 is arranged on the upper side of the supporting platform 1 in the height direction. The specific connection mode between the cleaning base 2 and the liquid supply structure and the cleaning body 26 is a hinged connection. As a convertible implementation mode, it can also be a sliding connection or a detachable and movable snap connection.

[0027] The liquid supply structure can spray a cleaning liquid onto the transfer plate 3 on the carrier platform 1. The cleaning liquid is used to dissolve the ink on the transfer plate 3. The specific composition of the cleaning liquid can be adaptively adjusted according to the composition of the ink to meet the dissolution requirements. The cleaning body 26 can clean the transfer plate 3 on the carrier platform 1. In this embodiment, the ink is removed by contact friction. As a convertible embodiment, the cleaning body 26 can also remove the ink in a non-contact manner, such as applying ultrasonic vibration to the transfer plate 3.

[0028] In this embodiment, the driving unit is arranged on the cleaning base 2, and the carrying platform 1 and the cleaning base 2 are suitable for relative movement under the action of the driving unit. During the relative movement, the carrying platform 1 is in a stationary state and the cleaning base 2 is in a moving state. In addition, preferably, the carrying platform 1 can also be provided with auxiliary structures such as bottom wheels or bottom slide rails, which are used to move to the position to be cleaned by external force before the relative movement occurs.

[0029] As a convertible embodiment, the driving unit can also be set on the carrying platform 1 to drive the carrying platform 1 to move relative to the cleaning base 2. As another convertible embodiment, the driving unit can also be evenly distributed on the carrying platform 1 and the cleaning base 2.

[0030] In this embodiment, the driving unit includes a power source and a transmission structure. The power source can be a motor, an electric push rod, an electric cylinder or a pneumatic cylinder, etc. The transmission structure can be a robotic arm or a gear rack structure, etc. The power source is connected to the cleaning base 2 through the transmission structure and drives the cleaning base 2 to move relative to the supporting platform 1.

[0031] A carrying platform 1 and a cleaning base 2 are provided which can move relative to each other under the action of a driving unit, so that a liquid supply structure and a cleaning body 26 on the cleaning base 2 can move relative to the transfer plate 3 on the carrying platform 1. Furthermore, when the carrying platform 1 and the cleaning base 2 move to be adjacent to each other, the liquid supply structure can spray cleaning liquid toward the transfer plate 3. At the same time, the cleaning body 26 performs contact cleaning on the surface of the transfer plate 3 by means of the relative movement between the two. The entire process is exerted by the driving unit to reduce or avoid manual participation, thereby realizing automatic cleaning and saving time and cost.

[0032] The cleaning base 2 moves in a directional manner under the action of the driving unit, and the liquid supply structure is arranged on the front side of the cleaning body 26 along the movement direction of the cleaning base 2. In this embodiment, the directional movement refers to the unidirectional movement of the cleaning base 2 along its own preset movement direction. In practice, the cleaning base 2 and the supporting platform 1 can complete the cleaning of the ink on the transfer plate 3 during a single relative movement. This arrangement can improve the cleaning efficiency while ensuring the cleaning effect. In addition, the liquid supply structure is arranged on the front side of the cleaning body 26 to ensure that during the directional movement, the ink has contacted the cleaning liquid and dissolved before the cleaning body 26 is cleaned.

[0033] As a convertible implementation, the cleaning base 2 can perform bidirectional reciprocating motion relative to the carrying platform 1 under the action of the driving unit, and the liquid supply structure can also be arranged on the front and rear sides of the cleaning body 26.

[0034] In addition, the carrying platform 1 includes a table top 11 and a platform body 12 .

[0035] The table 11 is arranged in a planar plate shape and is used to carry the transfer plate 3. The table 11 is provided with leakage holes 113, which are used to discharge the cleaning waste liquid after dissolving the ink to prevent the waste liquid from accumulating on the transfer plate 3. Furthermore, a structure such as a card slot or a card block can be installed on the table 11 to limit the transfer plate 3 to prevent the transfer plate 3 from shaking or deflecting. It can be understood that the transfer plate 3 can also be directly placed on the table 11 to prevent the transfer plate 3 from shaking or deflecting through the friction between the two.

[0036] The platform body 12 is disposed at the lower side of the table 11, and has a waste liquid chamber 121 therein, which is connected to the leakage hole 113 and is suitable for containing waste liquid. In this embodiment, the waste liquid chamber 121 is provided with a drain port 122 that passes through the platform body 12. As a convertible embodiment, the waste liquid chamber 121 can also be an independent container that can be directly taken out from the platform body 12.

[0037] In this embodiment, the table 11 is arranged horizontally, and the front and rear edges of the table 11 along the movement direction of the carrying platform 1 are defined as the first edge 111 and the second edge 112, and the leakage holes 113 are respectively arranged adjacent to the first edge 111 and the second edge 112. Preferably, each edge of the table 11 is provided with an anti-overflow convex edge to prevent the cleaning liquid from spilling and ensure that the waste liquid is discharged from the leakage holes 113.

[0038] The leakage holes 113 distributed in this way can push the waste liquid into the leakage holes 113 adjacent to the second edge 112 through the movement of the cleaning body 26 after the liquid supply structure sprays cleaning liquid onto the transfer plate 3 on the supporting platform 1, while the leakage holes 113 adjacent to the first edge 111 can discharge the refluxed waste liquid.

[0039] As a changeable implementation, the plurality of leakage holes 113 may be evenly distributed along the table top 11 , or may be distributed adjacent to each edge of the table top 11 .

[0040] As another convertible implementation, the table top 11 may be arranged at an angle, and the leakage holes 113 are distributed on the lower side of the table top 11 .

[0041] The transfer plate cleaning device further includes a first pump body 13 and a waste liquid treatment unit 14 .

[0042] The first pump body 13 is connected to the waste liquid chamber 121, specifically to the discharge port 122 of the waste liquid chamber 121. The waste liquid treatment unit 14 is connected to the first pump body 13, and is suitable for recovering waste liquid from the waste liquid chamber 121 under the action of the first pump body 13. In the present embodiment, the first pump body 13 and the waste liquid treatment unit 14 are both arranged outside the supporting platform 1 and are interconnected by a conduit. The waste liquid treatment unit 14 can be a separate container or a composite unit with additional structures such as filtration, sedimentation, and adsorption.

[0043] The transfer plate cleaning device further includes a cleaning structure, which is disposed on the cleaning base 2 and disposed toward the carrying platform 1, and is used to clean the cleaning liquid remaining on the plate surface of the transfer plate 3. Preferably, in this embodiment, the cleaning structure is specifically an air jet device, which cleans the cleaning liquid through airflow. It can be understood that the cleaning structure can also be equipped with an end of a water-absorbing material for absorbing the cleaning liquid.

[0044] Specifically, the cleaning structure includes a first nozzle 21 and a fan 22 .

[0045] The first nozzle 21 is hingedly connected to the cleaning base 2. The first nozzle 21 can overcome the friction force under the action of external force and rotate relative to the cleaning base 2, thereby correspondingly adjusting the angle of the first nozzle 21 relative to the supporting platform 1. Preferably, the first nozzle 21 is an air knife. As a convertible embodiment, a stepping motor or other structure can be added to the first nozzle 21 to accurately adjust the rotation angle of the first nozzle 21.

[0046] The fan 22 is connected to the first nozzle 21 and is suitable for supplying gas to the first nozzle 21. As a convertible implementation, the fan 22 can also be a high-pressure gas source, such as a high-pressure gas cylinder.

[0047] The liquid supply structure includes a second nozzle 23 and a second pump body 24. The second nozzle 23 is hingedly connected to the cleaning base 2, and is suitable for rotating relative to the cleaning base 2 under the action of an external force, and correspondingly adjusting the angle relative to the supporting platform 1. Preferably, the second nozzle 23 is a spray coating knife. As a convertible embodiment, a stepping motor or other structure can also be added to the second nozzle 23 to accurately adjust the rotation angle of the second nozzle 23.

[0048] One end of the second pump body 24 is connected to the second nozzle 23 , and the other end thereof is suitable for connecting to an external cleaning liquid source 25 for supplying the cleaning liquid to be sprayed out of the second nozzle 23 .

[0049] One end of the cleaning body 26 is hingedly connected to the cleaning base 2, and is suitable for rotating relative to the cleaning base 2 under the action of an external force, and correspondingly adjusting the angle relative to the carrying platform 1, and the other end of the cleaning body 26 abuts against the transfer plate 3 on the carrying platform 1. As a convertible embodiment, the cleaning body 26 may also include a stepping motor or other structures for accurately adjusting the rotation angle of the scraping structure.

[0050] Preferably, the cleaning body 26 is an elastic scraper, and one end of the cleaning body 26 abutting against the transfer plate 3 on the carrying platform 1 is set to an elastic material, such as composite rubber, etc., to avoid scratching the transfer plate 3. It can be understood that the end of the cleaning body 26 abutting against the transfer plate 3 on the carrying platform 1 can also be a brush head.
