Description

Technical Field

[0001] The present application relates to the technical field of coating tanks, and in particular to a splash-proof coating tank. Background Art

[0002] Print media is printing paper or photo paper. The printing media is coated with coating liquid to form a coated paper. There are tiny holes in the coated paper to absorb ink or toner and fix them to show the image.

[0003] Conventional coating technology on printing media production lines fixes a porous semicircular groove tube, allowing the coating liquid to flow down from the holes of the semicircular groove tube and pour onto the printing media. Then, under the action of gravity, the coating liquid naturally flows and completes the coating process. The semicircular groove tube used in this coating process has a large hole spacing, which makes it difficult to ensure that the coating liquid can flow evenly when dripping onto the printing media. When the leveling cannot be fully completed, the coating liquid will generate bubbles on the printing media, resulting in poor absorption of ink and toner in some areas.

[0004] In the prior art, a coating tank is connected to a motor in a transmission manner, and the coating tank is shaken above the printing medium to reduce the distance between the opening and the printing medium, so that the coating liquid can drip evenly on the printing medium, ensuring that the coating liquid can flow flat. However, when the coating tank shakes with the motor, the coating liquid is easily splashed out from the inside of the coating tank, wasting the coating liquid and increasing the cost. Utility Model Content

[0005] In view of this, the present application proposes an anti-splash coating tank to prevent the coating liquid from splashing from the inside of the coating tank to the outside.

[0006] According to one aspect of the present application, a splash-proof coating trough is provided, comprising: a coating trough body; the coating trough body comprises a bottom wall and a side wall, the side wall is arranged along the edge of the bottom wall and is surrounded above the bottom wall, and a coating hole is opened at the bottom of the coating trough, the coating hole is directly opposite to the paper production line, and a blocking portion is extended from the side wall of the coating trough body toward the opening direction of the pouring port; pulleys are provided on both side walls in the length direction of the coating trough body, the pulleys can slide along the printing medium production equipment, and the sliding direction of the pulley is perpendicular to the length direction of the printing medium.

[0007] In a possible implementation, there are multiple pulleys, which are arranged at equal intervals along the length direction of the coating tank body.

[0008] In one possible implementation, the pulleys along the length direction of the coating tank body correspond one to one.

[0009] In a possible implementation, the extending length of the blocking portion is in the range of 100 mm to 150 mm.

[0010] In a possible implementation, the pouring port is a square hole;

[0011] The blocking part is a square structure with a hollow interior and openings at both ends, and is adapted to the pouring port.

[0012] In a possible implementation, the extension length of the blocking portion is equal to the opening depth of the coating tank body;

[0013] The bottom of the blocking portion is flush with the top of the mounting bracket.

[0014] In one possible implementation, the cross-section of the coating tank body in the length direction is an isosceles trapezoidal structure.

[0015] In a possible implementation, the coating tank body includes a first side wall and a third side wall, a second side wall and a fourth side wall that are arranged opposite to each other, and a bottom wall;

[0016] The bottom wall is a square plate-like structure;

[0017] The first side wall, the second side wall, the third side wall and the fourth side wall are sequentially arranged above the bottom wall.

[0018] In a possible implementation, the first side wall and the third side wall are trapezoidal structures;

[0019] The second side wall and the fourth side wall are rectangular structures, and are respectively arranged perpendicularly to the two ends of the bottom wall in the length direction; and

[0021] In one possible implementation, the coating holes are arranged in a plurality of rows along the length direction of the coating tank body.

[0022] The beneficial effect of the anti-splash coating slot of the embodiment of the present application is as follows: the coating slot body is arranged on the mounting bracket, located above the printing medium, and the two ends of the coating slot body in the length direction are connected to the motor transmission, so that the coating slot body can shake in the direction perpendicular to the paper feeding of the printing medium. Among them, the coating slot body is hollow inside, and a pouring port is arranged on the top, and the coating liquid is poured into the inside of the coating slot body through the pouring port, and a coating hole is arranged at the bottom of the coating slot body, and as the motor drives the coating slot body in the direction perpendicular to the paper feeding direction of the printing medium, the coating liquid is evenly dripped on the printing medium. In addition, a blocking part is extended at the top of the coating slot body along the opening direction of the pouring port, and the blocking part extends the groove depth of the coating slot body in the vertical direction. In this way, the extended blocking part can prevent the coating liquid from splashing above the printing medium as the coating slot body shakes in the vertical direction.

[0031] Figure 1 A schematic diagram showing the main structure according to an embodiment of the present application is shown. Figure 1 As shown, the anti-splash coating tank of the embodiment of the present application includes: a coating tank body 100. The coating tank body 100 is arranged on a mounting bracket, and is connected to the motor through the two ends in the length direction, so as to drive the coating tank body 100 to shake in the direction perpendicular to the paper production line, reduce the opening distance of adjacent coating holes relative to the printing medium in the vertical direction, ensure that the coating liquid can drip evenly on the printing medium, and avoid bubbles caused by uneven leveling. In addition, the side wall of the coating tank body 100 extends toward the opening direction of the pouring port, and a blocking part 200 is extended. The blocking part 200 is arranged above the coating tank body 100. When the coating tank body 100 shakes with the motor, the blocking part 200 can prevent the liquid inside the coating tank body 100 from splashing out of the outside of the coating tank body 100. In this way, the coating liquid will not splash from the inside of the coating tank body 100, saving the amount of coating liquid used, and also preventing the coating liquid from splashing on the printing medium, preventing the coating liquid from flowing unevenly on the printing medium and generating bubbles. Pulleys 300 are provided on both sides of the coating tank body 100 in the length direction to improve the smoothness of the coating tank body 100 during the sliding process, and to prevent the coating tank body 100 from splashing due to poor sliding during the sliding process.

[0032] In one embodiment, the extended length of the blocking portion 200 is in the range of 100 mm to 150 mm, and the opening length of the coating tank body 100 is 150 mm. Thus, the extended length of the blocking portion 200 can ensure that the coating liquid does not splash out of the coating tank body 100 from the inside.

[0033] In a specific embodiment, the blocking part 200 is a square shell with two ends opened, which is adapted to the square pouring port. The blocking part 200 is made integrally with the coating tank body 100 to reduce the manufacturing process.

[0034] In a specific embodiment, the coating tank body 100 is disposed on a mounting bracket, and the top of the coating tank body 100 without the extended blocking portion is flush with the mounting bracket, so as to dispose the coating tank body 100 above the printing medium.

[0035] In a specific embodiment, the coating tank body 100 includes a first side wall 110 and a third side wall that are arranged opposite to each other, a second side wall 120 and a fourth side wall that are arranged opposite to each other, a bottom wall, and a blocking portion. The first side wall 110, the second side wall 120, the third side wall and the fourth side wall are sequentially arranged above the bottom wall to form a slot structure with an open top for placing the coating liquid. Coating holes are provided on the plate surface of the bottom wall to evenly drip the placed coating liquid onto the printing medium. The blocking portion is an extension of the first side wall 110, the second side wall 120, the third side wall and the fourth side wall, extending along the opening direction, thereby increasing the opening depth of the coating tank body 100 in the vertical direction to prevent the coating liquid in the shaking coating tank body 100 from splashing.

[0036] Furthermore, in this specific embodiment, the first side wall 110 and the third side wall arranged opposite to each other are trapezoidal, perpendicular to the two ends in the length direction of the bottom wall, the second side wall 120 and the fourth side wall arranged opposite to each other are rectangular, symmetrically arranged at the two ends in the width direction of the bottom wall, and the second side wall 120 and the fourth side wall are inclined and fixedly connected to the waist of the first side wall 110 and the third side wall to form a groove structure with a trapezoidal cross-section.

[0037] Furthermore, in this specific embodiment, the cross-section of the coating tank body 100 in the length direction is an isosceles trapezoidal structure. When the coating liquid is placed into the coating tank body 100, the coating liquid can drip smoothly onto the printing medium through the coating hole due to the effect of gravity. Since the coating tank body 100 is a structure that is wide at the top and narrow at the bottom, the potential energy of the coating liquid above the coating tank body 100 is increased, thereby improving the flow rate of the coating liquid and allowing the coating liquid to flow evenly on the printing medium.

[0038] Among them, pulleys 300 are arranged on both sides of the sliding direction of the coating tank body 100, namely on the second side wall 120 and the third side wall, which can allow the coating tank body 100 to slide on the mounting bracket, reduce the friction between the coating tank body 100 and the mounting bracket, reduce the gravity load, and improve the service life of the motor.

[0039] There are two pulleys 300 disposed on one side of the coating tank body 100, and the pulleys 300 are symmetrically disposed. In this way, the coating tank body 100 can slide stably on the mounting bracket under the drive of the motor to avoid splashing of the coating liquid.

[0040] In a specific embodiment, a plurality of coating holes are provided on the bottom wall of the coating tank body 100, and the coating holes are provided in a staggered manner from one end to the other end along the length direction of the bottom wall. The staggered coating holes cover the entire surface of the bottom wall, and when the coating liquid drips from the staggered coating holes, it can drip evenly onto the printing medium.

[0041] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
