Description

Technical Field

[0001] The utility model relates to the technical field of ink recovery, in particular to a device for collecting residual ink on the surface of anilox roller. Background Art

[0002] The flexographic printing machine uses a typical short ink path ink supply system with a relatively simple structure. It is mainly composed of four parts: ink tank, rubber roller, doctor blade and anilox roller. Among them, the anilox roller is the core component of the flexographic printing machine, which is responsible for evenly transferring a certain amount of ink to the printing plate.

[0003] The reference patent name is: A device for collecting residual ink on the surface of anilox roller (authorization announcement number: CN208263727U), which includes a collecting tank, a collecting hopper located at the upper part of the collecting tank, a screen plate arranged horizontally in the collecting hopper, a positioning seat arranged on the screen plate, and a positioning rod extending vertically upward from the positioning seat. The anilox roller can be sleeved on the outer periphery of the positioning rod from the inner cavity in the length direction, and is erected on the positioning seat from the lower end. The ink on the surface of the anilox roller flows into the collecting hopper through the mesh holes on the screen plate, and then flows into the collecting tank to complete the collection. The utility model drains and collects the residual ink on the anilox roller before cleaning the anilox roller. Therefore, it not only realizes the collection of ink to reduce the waste of ink, but also provides convenience for the subsequent cleaning process, greatly reducing the cleaning difficulty and cleaning cost.

[0004] Although this patent can achieve the effect of draining the residual ink on the anilox roller before cleaning, it may not be possible to collect all the residual ink on the anilox roller, especially those inks located in the grooves of the anilox roller or inaccessible parts, due to the method of waiting for the residual ink on the anilox roller to flow naturally into the collection box. These residual inks may affect the quality of the next round of printing, resulting in problems such as uneven color, blur or ghosting. In addition, if the ink stays on the anilox roller for too long, especially in a high temperature or poorly ventilated environment, the ink is easy to dry. The dried ink will form lumps that are difficult to remove, which not only affects the printing quality, but may also damage the anilox roller and shorten its service life.

[0005] Therefore, it is necessary to provide a new device for collecting residual ink on the surface of anilox roller to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a device for collecting residual ink on the surface of anilox roller.

[0007] The utility model provides a device for collecting residual ink on the surface of anilox roller, comprising a platform, a collecting assembly for collecting ink is installed at the top and bottom of the platform, and a draining mechanism for draining the residual ink on the anilox roller is installed at the top of the platform, and the draining mechanism comprises:

[0008] The support assembly is installed on the top of the platform, and includes a drain box fixed on the top of the platform. The top of the platform is provided with a groove, a filter plate is fixed on the inner side of the groove, a support column is fixed on the top of the filter plate, the outer wall of the support column is sleeved with an anilox roller, and the outer wall of the anilox roller is installed with a drain assembly for draining residual ink.

[0009] Preferably, the leaching component includes connecting columns symmetrically fixed on the top of the filter plate, a lifting groove is opened on the side where the two connecting columns are close to each other, a lifting plate is slidably connected to the inner side of the lifting groove, connecting strips are symmetrically fixed on the side of the lifting plate close to the anilox roller, ink-absorbing cotton is fixed on the bottom of the connecting strips, extrusion blocks are symmetrically fixed on the top of the filter plate, and a driving component for driving the lifting plate to rise and fall is installed on the side of the lifting plate away from the anilox roller.

[0010] Preferably, the driving assembly includes a sliding groove opened on the side of the lifting plate away from the anilox roller, the inner side of the sliding groove is slidably connected with a sliding column, a rotating disk is fixed to one end of the sliding column, a rotating rod is fixed to the outer wall of the rotating disk, the outer wall of the rotating rod is rotatably connected to the inner side of the leach box through a bearing, a support seat is fixed to the top of the platform, a motor is fixed to the inner side of the support seat, and the output end of the motor is fixed to one end of the rotating rod.

[0011] Preferably, the collection assembly comprises two supporting feet symmetrically fixed to the bottom of the platform, an anti-skid plate is fixed to the bottom of the supporting feet, and a collection box is arranged on the top of the anti-skid plate.

[0012] Preferably, a guide block is fixed to the bottom of the platform, and the outer wall of the guide block is arranged in an inclined shape.

[0013] Preferably, the top of the leach box is rotatably connected to a cover plate via an axle pin.

[0014] Compared with the related art, the device for collecting residual ink on the surface of the anilox roller provided by the utility model has the following beneficial effects:

[0015] 1. Due to the method of waiting for the residual ink on the anilox roller to flow naturally into the collection box, it may not be possible to collect all the residual ink on the anilox roller, especially the ink located in the grooves of the anilox roller or the hard-to-reach parts. These residual inks may affect the quality of the next round of printing, resulting in uneven colors, blur or ghosting, etc. By using ink-absorbing cotton, the residual ink on the surface of the anilox roller can be quickly and effectively absorbed to avoid excessive accumulation of ink on the anilox roller, which affects the subsequent printing quality. When the ink-absorbing cotton is saturated, most of the absorbed ink can be released by squeezing. In comparison, the automatically flowing ink not only speeds up the leaching efficiency, but also is simpler to operate;

[0016] 2. In addition, if the ink stays on the anilox roller for too long, especially in a high temperature or poorly ventilated environment, the ink will dry easily. The dried ink will form lumps that are difficult to remove, which will not only affect the printing quality, but may also damage the anilox roller and shorten its service life. By using ink-absorbing cotton, cleaning operations can be performed at any time as needed without waiting for the ink to automatically flow into the collection tank, which improves the flexibility and efficiency of the operation.
