具体实施方式Detailed ways
参照图1-2，本发明提出的一种薄膜生产用收卷装置，包括侧板1、切边组件2、第一导向辊5、成品膜收卷辊3、废料收卷辊4，第一导向辊5、成品膜收卷辊3和废料收卷辊4平行布置且均转动安装在侧板1上，切边组件2位于第一导向辊5和成品膜收卷辊3之间用于对经过第一导向辊5的薄膜进行切边处理，成品膜收卷辊3用于对经过切边处理后的成品膜进行收卷，废料收卷辊4用于对切边处理产生的废料进行收卷。With reference to Fig. 1-2, a kind of winding device for film production that the present invention proposes, comprises side plate 1, edge trimming assembly 2, first guide roller 5, finished film winding roller 3, waste material winding roller 4, the first The guide roller 5, the finished film winding roller 3 and the waste material winding roller 4 are arranged in parallel and are all rotatably installed on the side plate 1, and the trimming assembly 2 is positioned between the first guiding roller 5 and the finished film winding roller 3 for The film through the first guide roller 5 is trimmed, and the finished film winding roller 3 is used to wind the finished film after the trimming process, and the waste material winding roller 4 is used to collect the waste generated by the trimming process. roll.
收卷过程具体如下：薄膜在收卷前首先经过第一导向辊5导向后再经过切边组件2进行切边处理，切边组件将薄膜两边多余的长度部分切除，然后切除废边后的成品膜收卷在成品膜收卷辊3上，而切除的废边收卷在废料收卷辊3上。The details of the winding process are as follows: before winding, the film is guided by the first guide roller 5 and then trimmed by the trimming component 2. The trimming component cuts off the excess length on both sides of the film, and then cuts off the waste edge of the finished product The film is wound up on the finished film winding roll 3, while the scrap edge is wound on the scrap winding roll 3.
需要进一步说明的是，如果成品膜与废边在收卷过程中的张力不同，将会导致成品膜与废边分离点的两边在其收卷方向上的张力不同，成品膜的边缘可能会由于切边处理前与切边处理后的张力不同而翘起，影响成品膜的质量，为避免上述情况的发生，成品膜收卷辊3的收卷速度与废料收卷辊4的收卷速度相同，从而使得成品膜在切边处理前和切边处理后的沿其收卷方向的张力相同It needs to be further explained that if the tension between the finished film and the waste edge is different during the winding process, the tension between the two sides of the separation point of the finished film and the waste edge will be different in the winding direction, and the edge of the finished film may be due to The tension before and after edge trimming is different, which will affect the quality of the finished film. In order to avoid the above situation, the winding speed of the finished film winding roller 3 is the same as that of the waste winding roller 4. , so that the tension of the finished film along its winding direction is the same before and after edge trimming
具体参照图1和图3，在上述实施例中，切边组件2包括安装板22、第一导向轮23、第二导向轮24、第一刀片25，第一导向轮23、第一刀片25、第二导向轮24沿第一导向辊5长度方向依次安装在安装板22上，其中第一导向轮23和第二导向轮24可与第一导向辊5抵靠，以将薄膜在第一导向辊5的长度方向上进行固定，第一刀片25用于对经过第一导向轮23和第二导向轮24固定后的薄膜进行切边处理。With particular reference to Fig. 1 and Fig. 3, in the foregoing embodiment, trimming assembly 2 comprises mounting plate 22, first guide wheel 23, second guide wheel 24, first blade 25, first guide wheel 23, first blade 25 , The second guide roller 24 is installed on the installation plate 22 successively along the length direction of the first guide roller 5, wherein the first guide roller 23 and the second guide roller 24 can abut against the first guide roller 5, so that the film is placed on the first guide roller. The guide roller 5 is fixed in the length direction, and the first blade 25 is used to trim the film fixed by the first guide roller 23 and the second guide roller 24 .
切边组件2的使用过程如下：在第一刀片25对薄膜进行切边处理之前，薄膜被夹持在第一导向轮23、第二导向轮24与第一导向辊5之间，薄膜沿收卷方向运动，第一导向轮23、第二导向轮24与第一导向辊5一同转动，从而不会影响薄膜的收卷运动，但是第一导向轮23、第二导向轮24与第一导向辊5在第一导向辊5的长度方向上相对固定，因此薄膜在经过第一导向辊5时，其在第一导向辊5长度方向上的位置相对固定，避免薄膜在经过第一导向辊5时沿第一导向辊5的长度方向运动，导致第一刀片25的切边位置不固定，影响切边效果。The use process of the trimming assembly 2 is as follows: before the first blade 25 trims the film, the film is clamped between the first guide wheel 23, the second guide wheel 24 and the first guide roller 5, and the film is retracted along the Rolling direction movement, the first guide wheel 23, the second guide wheel 24 and the first guide roller 5 rotate together, thus can not affect the winding motion of film, but the first guide wheel 23, the second guide wheel 24 and the first guide roller Roller 5 is relatively fixed on the longitudinal direction of first guide roller 5, so film when passing through first guide roller 5, its position on the length direction of first guide roller 5 is relatively fixed, prevents film from passing through first guide roller 5 When moving along the length direction of the first guide roller 5, the trimming position of the first blade 25 is not fixed, which affects the trimming effect.
针对不同切边宽度的需求，第一刀片25的位置需要跟随切边宽度需求进行调节，为满足上述调节，本发明中的切边组件2还包括与第一导向辊5平行布置的矩形杆21，矩形杆21固定安装在侧板1上，安装板22沿第一导向辊5的长度方向滑动套接在矩形杆21上。For the requirements of different trimming widths, the position of the first blade 25 needs to be adjusted according to the trimming width requirements. In order to meet the above adjustments, the trimming assembly 2 in the present invention also includes a rectangular rod 21 arranged in parallel with the first guide roller 5 , the rectangular rod 21 is fixedly installed on the side plate 1 , and the mounting plate 22 is slidably sleeved on the rectangular rod 21 along the length direction of the first guide roller 5 .
在上述实施例中，安装板22与矩形杆21之间可以通过二者之间的摩擦力在矩形杆21的长度方向上进行相对固定，当安装板22受到的外力大于摩擦力时改变安装板22的相对位置，但是当第一刀片25在进行切边处理也有可能受到外力作用导致其移位，不够稳固。In the above embodiment, the mounting plate 22 and the rectangular rod 21 can be relatively fixed in the length direction of the rectangular rod 21 through the friction force between them. 22, but when the first blade 25 is trimming, it may also be displaced by an external force, which is not stable enough.
具体参照图4，为解决上述问题，在矩形杆21沿其长度方向依次开设有固定槽211，安装板22上固定有电动伸缩杆221，且电动伸缩杆221的移动端固定有卡板222，电动伸缩杆221可带动卡板222与部分固定槽211卡合。Referring specifically to Fig. 4, in order to solve the above-mentioned problems, the rectangular rod 21 is provided with a fixed groove 211 along its length direction successively. The electric telescopic rod 221 can drive the clamping plate 222 to engage with part of the fixing groove 211 .
当卡板222与部分固定槽211卡合时，安装板22与矩形杆21在矩形杆21的长度方向上相对固定，需要调节安装板22上第一刀片25的位置时，电动伸缩杆221带动卡板222与固定槽211分离，此时安装板22可以在矩形杆21上滑动至需要的位置。When the clamping plate 222 is engaged with the part of the fixing groove 211, the mounting plate 22 and the rectangular rod 21 are relatively fixed in the length direction of the rectangular rod 21. When the position of the first blade 25 on the mounting plate 22 needs to be adjusted, the electric telescopic rod 221 drives The clamping plate 222 is separated from the fixing groove 211 , and at this time, the mounting plate 22 can slide on the rectangular rod 21 to a desired position.
安装板22上沿其长度方向依次转动安装有多个第二导向辊223，且第二导向辊223可与经过分切处理后的成品膜的两侧下方贴合以对成品膜的两侧边形成支撑。On the mounting plate 22, a plurality of second guide rollers 223 are sequentially rotated along its length direction, and the second guide rollers 223 can be attached to the lower sides of the finished film after slitting to align the two sides of the finished film. form a support.
需要进一步说明的是，为方便将下一组薄膜穿过第一导向轮23、第二导向轮25与第一导向辊5之间，切边组件2还包括第二驱动机构，第二驱动机构安装在侧板1上并用于带动矩形杆21转动，矩形杆21带动安装板22转动以使得第一导向轮23、第二导向轮24与第一导向辊5抵靠或分离，其中抵靠状态示意图参照图5，分离状态参照图6，且矩形杆21位于第一导向轮23与第二导向辊223之间。It should be further explained that, for the convenience of passing the next group of films between the first guide wheel 23, the second guide wheel 25 and the first guide roller 5, the trimming assembly 2 also includes a second drive mechanism, the second drive mechanism Installed on the side plate 1 and used to drive the rectangular rod 21 to rotate, the rectangular rod 21 drives the mounting plate 22 to rotate so that the first guide wheel 23, the second guide wheel 24 and the first guide roller 5 abut or separate, wherein the abutting state Refer to FIG. 5 for the schematic diagram, and FIG. 6 for the separated state, and the rectangular rod 21 is located between the first guide wheel 23 and the second guide roller 223 .
当首组薄膜收卷完成后，需要对下一组薄膜进行切边收卷处理时，薄膜需要通过第一导向轮、第二导向轮与第一导向辊之间的空间，此时第二驱动机构通过矩形杆21带动安装板22转动至第一导向轮23、第二导向轮24与第一导向辊5分离的状态，将薄膜穿过第一导向辊5后，第二驱动机构再带动矩形杆21反向转动，矩形杆21通过安装板22带动第一导向轮23、第二导向轮25与第一导向辊5抵靠，薄膜被夹持在第一导向轮23、第二导向轮25与第一导向辊5之间。When the first set of film winding is completed, when the next set of film needs to be trimmed and wound, the film needs to pass through the space between the first guide wheel, the second guide wheel and the first guide roller. At this time, the second drive The mechanism drives the mounting plate 22 to rotate through the rectangular rod 21 to the state where the first guide wheel 23 and the second guide wheel 24 are separated from the first guide roller 5. After passing the film through the first guide roller 5, the second driving mechanism drives the rectangular The rod 21 rotates in reverse, the rectangular rod 21 drives the first guide wheel 23, the second guide wheel 25 to abut against the first guide roller 5 through the mounting plate 22, and the film is clamped on the first guide wheel 23, the second guide wheel 25 and the first guide roller 5.
收卷完成后，需要将废边从废料收卷辊4上取下，然后进行加热融化回收，为加快聚酰亚胺废料的回收效率，可以将废料先进行粉碎再进行加热回收，因此为方便对废料收卷辊4的后续加工回收，在侧板1上转动安装有双向丝杆6，双向丝杆6的外侧螺旋套接有滑块7，滑块7的一侧固定有与废料收卷辊4同轴布置的圆环8，圆环8内圈壁上固定有第二刀片9，且第二刀片9的一端与废料收卷辊4的外壁贴合。After the winding is completed, the waste edge needs to be removed from the waste winding roller 4, and then heated and melted for recovery. In order to speed up the recovery efficiency of polyimide waste, the waste can be crushed first and then heated and recovered, so it is convenient For the follow-up processing and recycling of the waste material winding roller 4, a bidirectional screw rod 6 is installed in rotation on the side plate 1, and the outer side of the bidirectional screw rod 6 is helically sleeved with a slider 7, and one side of the slider 7 is fixed with a waste material rewinding roller. The ring 8 arranged coaxially with the roller 4 has a second blade 9 fixed on the inner wall of the ring 8 , and one end of the second blade 9 is attached to the outer wall of the waste winding roller 4 .
废料从废边收卷辊4上取下的过程如下，转动双向丝杆6，由于滑块7与双向丝杆6螺旋连接，并且滑块7受圆环8的限制不能随双向丝杆6一同转动，因此滑块7将会带动圆环8及第二刀片9沿废料收卷辊4的长度方向运动，第二刀片9将缠绕在废料收卷辊4上的废边切断，切断后的废料从废料收卷辊4上掉落，可以在废料收卷辊4的下方放置用于接收切碎后的废料的集料箱，第二刀片9的数量可以根据废边的粉碎程度进行设置，下料的同时还能对废料进行一轮粉碎，方便废料的回收。The process of removing the waste material from the waste edge winding roller 4 is as follows, turn the two-way screw mandrel 6, because the slide block 7 is spirally connected with the two-way screw mandrel 6, and the slide block 7 is restricted by the ring 8 and cannot be moved together with the two-way screw mandrel 6 Rotate, so the slide block 7 will drive the ring 8 and the second blade 9 to move along the length direction of the waste winding roller 4, and the second blade 9 will cut off the waste edge wound on the waste winding roller 4, and the waste after cutting Falling from the waste rewinding roller 4, a collection box for receiving the shredded waste can be placed under the waste rewinding roller 4, and the quantity of the second blade 9 can be set according to the degree of crushing of the waste edge. At the same time, it can crush the waste in one round, which is convenient for the recycling of waste.
移动滑块7上开设有卡槽71，安装板22靠近成品膜收卷辊3的一端可适配插入卡槽71内。A slot 71 is provided on the moving slider 7 , and the end of the mounting plate 22 close to the winding roller 3 of the finished film can be fitted and inserted into the slot 71 .
还包括第一驱动机构，第一驱动机构安装在侧板1上用于带动成品膜收卷辊3和废料收卷辊4同步转动。It also includes a first driving mechanism, which is installed on the side plate 1 and is used to drive the finished film winding roller 3 and the waste material winding roller 4 to rotate synchronously.
