技术领域Technical field
本发明涉及印刷设备技术领域，尤其涉及一种油墨挤出装置。The invention relates to the technical field of printing equipment, and in particular to an ink extrusion device.
背景技术Background technique
传统的印刷油墨大多使用金属或塑料硬质密封包装的油墨桶，导致在印刷操作时，需要人工将油墨从油墨桶转移至墨斗池内，操作非常不便且不易将油墨完全取净。Conventional printing inks mostly use metal or plastic rigid sealed ink drums, which requires manual transfer of ink from the ink tank to the ink fountain during printing operations. The operation is very inconvenient and it is not easy to completely remove the ink.
为此业界也开发出了一些挤出机用于挤出金属或塑料油墨桶内的粘稠膏状印刷油墨。油墨在活塞盘的挤压下，从排料口排出。应用此设备要求油墨桶内径圆度很好。但在实际应用中存在问题是：目前的油墨桶的圆度尺寸达不到精度要求，油墨桶内径误差稍大，就会出现挤出不干净甚至油墨泄露的问题。残留的油墨在金属或塑料油墨桶内固化，而这些油墨固化后的废弃物是不可燃的，并且具有毒性，所以还没有有效环保回收的途径。To this end, some extruders have also developed viscous paste printing inks for extruding metal or plastic ink drums. The ink is discharged from the discharge opening under the squeeze of the piston disk. Applying this device requires a good roundness of the inner diameter of the ink drum. However, the problem in practical application is that the roundness of the current ink drum does not meet the accuracy requirement, and the inner diameter error of the ink barrel is slightly larger, and the problem of uncleanness or even ink leakage may occur. Residual inks are solidified in metal or plastic ink drums, and the solidified waste of these inks is non-flammable and toxic, so there is no effective way to recycle them.
为此，我们发明了一种软包装的油墨包装物，能够解决环保回收的问题，但如何使用该软包装，如何自动化的实现软包装的油墨包装物中的油墨挤出，是亟待解决的问题。To this end, we have invented a flexible packaging ink package that can solve the problem of environmental recycling, but how to use the flexible packaging, how to automatically achieve ink extrusion in the flexible packaging ink packaging, is an urgent problem to be solved.

为保证油墨包装物8在挤压过程中能够收到足够的摩擦力随压辊32的转 动而向上垂直移动，两根压辊之间的间距可以调整为不大于油墨包装物8的包装厚度，从而也保证油墨包装物8中的油墨因收到足够的压力被最大限度的从油墨包装物8中排空。In order to ensure that the ink package 8 can receive sufficient friction during the pressing process, the pressure roller 32 is rotated. Moving vertically upwards, the spacing between the two press rolls can be adjusted to be no greater than the package thickness of the ink package 8, thereby also ensuring that the ink in the ink package 8 is maximally removed from the ink package due to sufficient pressure. Empty in item 8.
在本实施例中，油墨包装物8可以具体为由内向外具有防氧化涂层、纸质包装层和防水包装层三层结构的油墨软包装袋，用于容置氧化聚合型油墨；也可以是由内向外具有可水解涂层、纸质包装层和抗紫外线包装层三层结构的油墨软包装袋，用于容置紫外线固化型油墨等。In this embodiment, the ink package 8 may specifically be an ink flexible packaging bag having an anti-oxidation coating, a paper packaging layer and a waterproof packaging layer from the inside to the outside, for accommodating the oxidative polymerization type ink; An ink flexible packaging bag having a three-layer structure of a hydrolyzable coating, a paper packaging layer and an anti-UV packaging layer from the inside to the outside, for accommodating ultraviolet curable inks and the like.
在使用时，需要先去掉防水包装层，然后将纸质包装层暴露在最外层的油墨软包装袋由两根压辊32的下方***两根压辊32间。压辊装置3还包括位置传感器(图中未示出)，用于探测是否在两根压辊32的下方置入物体。当探测到时，位置传感器产生转动控制信号发送给压辊驱动电机31。压辊驱动电机31带动两根压辊32转动第一预设角度，例如540°或720°等，将油墨包装物8的一端夹入两根压辊32之间。由于两根压辊32之间的压力作用，夹入的油墨包装物8不会从两根压辊32之间掉落出。In use, the waterproof packaging layer is first removed, and then the paper packaging layer is exposed to the outermost ink flexible packaging bag and inserted between the two pressure rollers 32 under the two pressure rollers 32. The pressure roller device 3 further includes a position sensor (not shown) for detecting whether or not an object is placed under the two pressure rollers 32. When detected, the position sensor generates a rotation control signal to be sent to the pressure roller drive motor 31. The pressure roller driving motor 31 drives the two pressure rollers 32 to rotate by a first predetermined angle, for example, 540° or 720°, etc., and one end of the ink package 8 is sandwiched between the two pressure rollers 32. Due to the pressure between the two pressure rollers 32, the sandwiched ink package 8 does not fall out between the two pressure rollers 32.
在具体的应用中，位置传感器可以采用光电传感器，也可以采用机械传感器。In specific applications, the position sensor can be either a photoelectric sensor or a mechanical sensor.
在油墨包装物8夹入两根压辊32之后，就可以开始向墨池9注入油墨了。在启动注入时，可以通过按下油墨挤出装置上的注墨启动按钮(图中未示出)启动，也可以通过与油墨挤出装置相连接的控制设备，如计算机等，发送注墨启动信号来进行启动。After the ink package 8 is sandwiched between the two pressure rollers 32, ink can be injected into the ink pool 9. When the injection is started, it can be started by pressing the ink-initiating button (not shown) on the ink extrusion device, or by injecting the ink through a control device connected to the ink extrusion device, such as a computer. Signal to start.
在注墨过程中，第一运动平台12、第二运动平台22的移动分别与两根压辊32的相向同步转动相联动，以保证注墨的均匀性和平稳性。During the priming process, the movements of the first motion platform 12 and the second motion platform 22 are respectively linked with the phasewise synchronous rotation of the two pressure rollers 32 to ensure uniformity and smoothness of the ink injection.
具体的，在注墨过程中，挤压于两根压辊32之间的油墨包装物8，随两根压辊32的相向同步转动，向相对于压辊32垂直向上移动，通过挤压将油墨包装物8中容置的油墨挤出注入至墨池9内。Specifically, during the ink filling process, the ink package 8 extruded between the two pressure rollers 32 is synchronously rotated with the opposing directions of the two pressure rollers 32, and moves vertically upward relative to the pressure roller 32, and is pressed by extrusion. The ink contained in the ink package 8 is extrusion-injected into the ink pool 9.
此时，第一运动平台12在横向导轨平台1上的第一驱动电机13的驱动 下，随两根压辊32的相向同步转动，沿墨池9平墨斗辊91往复移动，以保证油墨在挤出过程中，相对均匀的注入到墨池9的墨槽中，避免在同一位置挤压油墨造成油墨溢出墨槽，而其他位置缺墨造成供墨不足，造成印刷品质量事故。At this time, the driving of the first driving motor 13 of the first motion platform 12 on the lateral rail platform 1 Next, as the two pressure rollers 32 are synchronously rotated, the flat ink fountain roller 91 reciprocates along the ink pool 9 to ensure that the ink is relatively uniformly injected into the ink tank of the ink pool 9 during the extrusion process, avoiding the same position. Squeezing the ink causes the ink to overflow the ink tank, while the lack of ink at other locations causes insufficient ink supply, resulting in print quality accidents.
进一步的，在横向导轨11的两端具有限位装置111，第一运动平台12沿横向导轨11由横向导轨11的一端至另一端移动到与限位装置111相接触时，改变移动方向再沿横向导轨11移动，直至到达对端的限位装置111后再次改变运动方向。Further, at both ends of the lateral rail 11 there is a limiting device 111. When the first moving platform 12 is moved from one end to the other end of the lateral rail 11 along the lateral rail 11 to contact with the limiting device 111, the moving direction is changed. The transverse rail 11 moves until it reaches the opposite end stop 111 and changes the direction of movement again.
同时，第二运动平台22在纵向导轨平台2上的第二驱动电机(图中未示出)的驱动下，产生与油墨包装物8的移动方向相反、位移相同的移动，使油墨包装物8的油墨流出位置与距离墨池9的高度始终保持不变。At the same time, under the driving of the second driving motor (not shown) on the longitudinal rail platform 2, the second moving platform 22 generates a movement opposite to the moving direction of the ink package 8, and the displacement is the same, so that the ink package 8 The ink outflow position and the height from the ink pool 9 are always constant.
当设定压辊32的旋转速度为恒定时，第一运动平台12和第二运动平台22的运动匀速的，因此可以更加精确的控制加在墨槽中的油墨是均匀加入的，保证油墨辊91上各个位置的油墨厚度都是均匀的。When the rotational speed of the set pressure roller 32 is constant, the movements of the first motion platform 12 and the second motion platform 22 are uniform, so that it is possible to more precisely control the ink added in the ink tank to be uniformly added, and to ensure the ink roller. The ink thickness at each position on 91 is uniform.
当油墨包装物8随两根压辊32的相向同步转动垂直向上移动至一定位置时，位置传感器无法再探测到两根压辊32的下方有物体。此时位置传感器产生制动控制信号发送给压辊驱动电机31，控制两根压辊32停止继续转动。同时，与压辊32联动的第一运动平台12和第二运动平台22分别在第一驱动电机13和第二驱动电机的控制下停止转动。When the ink package 8 is vertically moved up to a certain position with the relative rotation of the two pressure rollers 32, the position sensor can no longer detect an object below the two pressure rollers 32. At this time, the position sensor generates a brake control signal to be sent to the pressure roller drive motor 31, and controls the two pressure rollers 32 to stop continuing to rotate. At the same time, the first motion stage 12 and the second motion stage 22, which are interlocked with the pressure roller 32, stop rotating under the control of the first drive motor 13 and the second drive motor, respectively.
当注墨完毕后，可由操作人员调整两根压辊32之间的间距取出挤压干净的油墨包装物8，也可通过控制压辊32反转，将油墨包装物8从两根压辊32之间退出。After the ink filling is completed, the operator can adjust the distance between the two pressure rollers 32 to take out the squeezed ink package 8, or control the pressure roller 32 to reverse, and the ink package 8 is taken from the two pressure rollers 32. Exit between.
此外，为了使油墨包装物8的回收满足纸制品回收的条件，即废纸回收时残留的油墨需要为固化状态，从而不会对废纸回收***造成新的污染，本发明实施例提供的油墨挤出装置还包括有紫外线(UV)照射光源，对挤出油墨的油墨包装袋8进行UV照射使残留油墨固化。 In addition, in order to make the recovery of the ink package 8 satisfy the condition of paper product recovery, that is, the ink remaining in the waste paper recovery needs to be in a solidified state, so as not to cause new pollution to the waste paper recycling system, the ink provided by the embodiment of the present invention The extrusion device further includes an ultraviolet (UV) illumination source, and the ink package 8 of the extruded ink is subjected to UV irradiation to cure the residual ink.
具体的，如图4所示，紫外线照射光源4设置于第二运动平台22上，水平位置置于两根压辊32之上；紫外线照射光源4为多个，呈水平设置为一排，射出波长范围为390nm-400nm的紫外光，照射在油墨包装物8通过两根压辊32间的部分，使残留的油墨通过紫外线固化。由此，UV固化油墨的过程可以随油墨挤出的过程同时完成，不会增加额外的人工操作，也不会耗费额外的时间再对油墨包装物8进行处理，即可满足对油墨包装物8进行环保回收的条件。Specifically, as shown in FIG. 4, the ultraviolet illuminating light source 4 is disposed on the second moving platform 22, and the horizontal position is placed on the two pressing rollers 32; the ultraviolet illuminating light source 4 is plural, and is horizontally arranged in a row, and is emitted.
