Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a drying device for preparing a dispersed light source curved surface sheet. Background Art

[0002] 3D grating card is also called scattered light source curved sheet. Its production process requires first pouring molten plastic pellets into the mold, so that one side of the plastic plate is squeezed into columnar lines, and the other side remains flat; after the curved sheet is demolded, the corresponding pattern is sprayed on the surface, and then the curved sheet with the pattern is placed in the drying line for drying.

[0003] In the existing drying line, the curved sheet is fed to the bottom of the drying lamp of the dryer through the conveyor line, and the moisture on the surface of the curved sheet arranged along the length direction of the conveyor line is dried by multiple drying lamps arranged along the length direction of the conveyor line. However, since the curved sheet is a thin sheet with a light weight, if the conveyor line speed is fast, the air convection with the curved sheet will generate a differential wind force, blowing the curved sheet to the ground. The conveying speed of the conveyor line is greatly limited. Therefore, in the current drying device for sheet preparation, the conveying speed of the conveyor line is slow, which is difficult to match the printing speed of the previous printing process. Therefore, there is often a pile of materials between the printing supply and demand and the drying supply and demand, or the printing machine stops working for a period of time, and then continues to work after the receiving platform of the printing machine is emptied, which seriously affects the continuity of production and reduces production efficiency.

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the utility model discloses a drying device for preparing a curved sheet with a dispersed light source, which comprises a conveyor line assembly and a drying bracket 2; the drying bracket 2 is in an "L" shape; a plurality of drying lamps 3 are arranged on the drying bracket 2 at a position above the conveyor line assembly; the conveyor line assembly comprises a fixed bracket 5, two rollers rotatably connected to the fixed bracket 5, a conveyor belt 1 stretched between the two rollers, and a driving module 6 for driving the rollers to rotate; the driving module 6 is composed of a reduction box and a motor, and the motor drives the reduction box to move and drives the rollers to rotate, so that the conveyor belt 1 moves, and the drying lamp 3 dries the ink of the curved sheet on the conveyor belt 1; a hollow shell 4 is arranged between the two rollers; a plurality of cavity vacuum holes are evenly distributed on the top surface of the hollow shell 4; a plurality of conveyor belt holes 101 are evenly distributed on the surface of the conveyor belt 1;

[0025] Two parallel guide rails 12 are fixed on the fixed bracket 5; the length direction of the guide rails 12 is the same as the width direction of the conveyor line assembly;

[0026] Both sides of the hollow shell 4 are provided with connecting strips 402; the connecting strips 402 are provided with guide rail grooves 402a which are slidably connected with the guide rail 12; the guide rail 12 is embedded in the guide rail grooves 402a;

[0027] The conveyor belt 1 is an annular structure and is sleeved outside the hollow shell 4;

[0028] The hollow shell 4 is connected to the vacuum equipment; the printed product is placed on the surface of the conveyor belt 1, and the negative pressure generated by the hollow shell 4 causes the conveyor belt holes 101 to adsorb the curved sheet on the conveyor belt 1 and move at the same speed as the conveyor belt 1. After the curved sheet is adsorbed on the surface of the conveyor belt 1, the wind force generated by the curved sheet when it moves relative to the air is difficult to blow the curved sheet away from the conveyor belt 1, so that the conveyor belt 1 can run at a faster speed, improve the conveying efficiency of the curved sheet on the drying line, and make the connection between the printing and drying stations in the production of curved sheets more coherent, thereby improving production efficiency; the hollow shell 4 and the fixed bracket 5 are connected by rails, which are convenient for disassembly and assembly.

[0029] As a preferred embodiment of the present invention, a stopper is provided at one end of the guide rail 12 and is arranged opposite to the connecting bar 402; a movable stopper assembly is provided at the other end of the guide rail 12; the movable stopper assembly comprises a telescopic stopper rod 7, a hinge shaft 8 and a swing rod 9; the telescopic stopper rod 7 is connected to the outer surface of the hollow shell 4; the swing rod 9 is connected to the guide rail 12 through the hinge shaft 8; the horizontal height of the hinge shaft 8 is higher than the height of the telescopic stopper rod 7;

[0030] After the guide rail groove 402a is inserted into the guide rail 12, the rocker arm 9 and the block respectively block the two sides of the connecting strip 402, so that the connecting strip 402 cannot be pulled out from the guide rail 12, thereby fixing the hollow shell 4 on the fixed bracket 5; when the hollow shell 4 needs to be removed from the fixed bracket 5, the rocker arms 9 at both ends are rotated around the hinge shaft 8 until the rocker arm 9 and the connecting strip 402 are completely misaligned, and the connecting strip 402 is not hindered from being pulled out from the guide rail 12, and the empty adsorption cavity 4 can be pulled out from the fixed bracket 5 along the length direction of the guide rail 12; the horizontal height of the hinge shaft 8 is higher than the height of the telescopic stop rod 7, so that the rocker arm 9 is tilted downward when it is placed on the telescopic stop rod 7, thereby reducing the risk of the hollow shell 4 derailing due to the counterclockwise swing of the rocker arm 9.

[0031] As a preferred embodiment of the utility model, the rocker arm 9 is threadedly connected with an anti-slip bolt 10; the end of the anti-slip bolt 10 is pressed against the surface of the hollow shell 4; in the working state, the anti-slip bolt 10 is pressed against the hollow shell 4, which increases the difficulty of the rocker arm 9 to rotate around the hinge shaft 8 and prevents the rocker arm 9 from loosening due to vibration; when it is necessary to remove the hollow shell 4, the anti-slip bolt 10 is turned to separate it from the surface of the hollow shell 4, and a thrust is applied to the rocker arm 9 to make the rocker arm 9 rotate.

[0032] As a preferred embodiment of the present invention, the telescopic blocking rod 7 is composed of a main blocking rod 701 and a rotating shaft 702 fixed on the side surface of the main blocking rod 701; an L-shaped groove 401 is provided on the surface of the hollow shell 4; the L-shaped groove 401 is composed of a first groove 401a and a second groove 401b; the rotating shaft 702 is rotatably connected to the second groove 401b; the first groove 401a is arranged on the path where the main blocking rod 701 rotates around the rotating shaft 702; a torsion spring 11 is connected between the inner side wall of the second groove 401b and the rotating shaft 702;

[0033] Under the action of the torsion spring 11, the telescopic stop rod 7 is disengaged from the first slot 401a and extended to the outside, preventing the rocker arm 9 from flipping downward; when the rocker arm 9 needs to be swung downward, the elastic force of the torsion spring 11 is overcome, and the main stop rod 701 is rotated around the rotating shaft 702 until the main stop rod 701 is completely embedded in the first slot 401a, without hindering the rocker arm 9 from swinging downward. This allows the rocker arm 9 to be misaligned with the hollow shell 4. After the rocker arm 9 is facing downward, it will not automatically swing upward due to the action of gravity, which makes it more convenient to assemble the hollow shell 4 and the fixed bracket 5, and to facilitate the cleaning of the hollow shell 4.

[0034] When the utility model is used, the driving module is composed of a reduction box and a motor. After the motor drives the reduction box to move, it drives the roller to rotate, so that the conveyor belt moves, and the drying lamp dries the ink on the curved surface sheet on the conveyor belt; the conveyor belt is an annular structure, which is sleeved on the outside of the hollow shell; the hollow shell is connected to the vacuum equipment; the printed products are placed on the surface of the conveyor belt, and the negative pressure generated by the hollow shell makes the small holes of the conveyor belt adsorb the curved surface sheet on the conveyor belt and move at the same speed as the conveyor belt. After the curved surface sheet is adsorbed on the surface of the conveyor belt, the wind force generated by the curved surface sheet when it moves relative to the air is difficult to blow the curved surface sheet away from the conveyor belt, so that the conveyor belt can run at a faster speed, thereby improving the conveying efficiency of the curved surface sheet on the drying line, making the curved surface sheet printing in the production The connection between the two brush drying stations is more coherent, which improves production efficiency; the hollow shell and the fixed bracket are connected by a track, which is convenient for disassembly and assembly; after the guide rail groove is inserted into the guide rail, the rocker arm and the stopper are respectively blocked on both sides of the connecting strip, so that the connecting strip cannot be pulled out from the guide rail, thereby fixing the hollow shell on the fixed bracket; when the hollow shell needs to be removed from the fixed bracket, the rocker arms at both ends are rotated around the hinge shaft until the rocker arm and the connecting strip are completely misaligned, and the connecting strip is not hindered from being pulled out of the guide rail, and the empty adsorption cavity can be pulled out from the fixed bracket along the length direction of the guide rail; the horizontal height of the hinge shaft is higher than the height of the telescopic stop rod, so that the rocker arm is tilted downward when the telescopic stop rod is in the state, reducing the risk of the hollow shell derailing due to the counterclockwise swing of the rocker arm.

[0035] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
