This folding machine has the characteristics of high folding efficiency, stable work, and low noise. The existing folding machines all feed horizontally, that is, the stack of paper is placed horizontally on the stacking platform, and the paper enters the machine horizontally one by one. This folding machine is suitable for standard size paper, but for longer paper In general, this folding machine is not very suitable, because the long paper placed horizontally on the stacking platform will occupy a lot of space, and it is also very inconvenient for the stacking of paper.

具体实施方式detailed description
如图1与2所示，该高速负吸辊式斜进料折页机包括机架1、堆放平台2、折页机构 4以及送纸机构3。堆放平台2用于放置纸堆，即药物说明书；折页机构4用于完成纸张的折页，可以对折一次或者多次；而送纸机构3用于将堆放平台2上的纸堆从底部一张张送到折页机构4，最后由折页机构4完成折纸任务。As shown in FIGS. 1 and 2, the high-speed negative suction roller type oblique feed folding machine includes a frame 1, a stacking platform 2, a folding mechanism 4, and a paper feeding mechanism 3. The stacking platform 2 is used to place paper stacks, that is, drug instructions; the folding mechanism 4 is used to complete the folding of the paper, and can be folded one or more times; and the paper feeding mechanism 3 is used to stack the paper stack on the stacking platform 2 from the bottom. The sheets are sent to the folding mechanism 4, and finally the folding mechanism 4 completes the folding task.
一般水平进料式折页机的送纸机构3包括有转动配合送纸的负吸辊筒32与送纸压轮31，负吸辊筒32的辊面上设有与真空源相连的负吸孔320,为了实现送纸，水平进料式折页机的负吸辊筒32与送纸压轮31均安装在滑块上，通过滑块的移动以及负吸辊筒32与送纸压轮31的配合转动实现送纸。The paper feeding mechanism 3 of the general horizontal feed type folding machine includes a negative suction roller 32 and a paper feeding pressure roller 31 which rotate to match the paper feeding, and the negative suction roller 32 is provided with a negative suction connected to a vacuum source on the roller surface Hole 320, in order to realize paper feeding, the negative suction roller 32 and paper feed pressure roller 31 of the horizontal feed folding machine are both installed on the slider, through the movement of the slider and the negative suction roller 32 and paper feed pressure roller The coordinated rotation of 31 realizes paper feeding.
如图1所述，本发明的堆放平台2为斜向设置，由于堆放平台2斜向设置，通过滑块的移动无法实现送纸，为了配合斜向设置的堆放平台2，本发明的负吸辊筒32与驱动负吸辊筒32在送纸压轮31上沿弧面来回转动的吸纸传动机构传动连接。如图5所述，由于负吸辊筒32是在送纸压轮31上沿弧面来回转动，因此其运动轨迹从起点到终点也是一条斜线，刚好与堆放平台2的斜方向相对应。如图5与图6所示，当负吸辊筒32通过其负吸孔320吸附住纸张的前边缘时，吸纸传动机构驱动负吸辊筒32在送纸压轮31上沿送纸压轮31的弧面向左下角方向移动(图6中的方向)，即向堆放平台2的倾斜方向转动，这样纸张就会顺利地绕在负吸辊筒32上，换个角度讲，就是负吸辊筒32在转动的同时顺着纸张走，让纸张自然而然卷在负吸辊筒32上，而不是强拽纸张；这样纸张的前边就大部分绕在负吸辊筒32上，由于纸张被上面纸堆压着的部分减少，而且进入到负吸辊筒32与送纸压轮31之间，负吸辊筒32上的压纸轴承322与送纸压轮31就夹住纸张将其抽出并输送到下方(负吸辊筒32上的负吸孔320负责吸纸，压纸轴承322用于将纸张压在送纸压轮31上，由于压纸轴承322可转动，因此负吸辊筒32来回转动时，压纸轴承322与送纸压轮31压着纸张不会对纸张产生阻力)；当纸张被输送到下方后，吸纸传动机构驱动负吸辊筒32在送纸压轮31上沿送纸压轮31的弧面向右上角方向移动(图5中的方向)，重新抽取下一张纸张。As shown in FIG. 1, the stacking platform 2 of the present invention is arranged obliquely. Since the stacking platform 2 is arranged obliquely, paper movement cannot be realized by the movement of the slider. In order to cooperate with the stacking platform 2 provided obliquely, the negative suction of the present invention The roller 32 is in driving connection with a paper suction transmission mechanism that drives the negative suction roller 32 to rotate back and forth along the arc surface on the paper feed pressure roller 31. As shown in FIG. 5, since the negative suction roller 32 rotates back and forth along the arc surface on the paper feed pressure roller 31, its movement trajectory is also a diagonal line from the start point to the end point, which corresponds exactly to the oblique direction of the stacking platform 2. As shown in FIGS. 5 and 6, when the negative suction roller 32 sucks the front edge of the paper through its negative suction hole 320, the suction paper transmission mechanism drives the negative suction roller 32 on the paper feed roller 31 along the paper feed pressure The arc of the wheel 31 moves in the direction of the lower left corner (the direction in FIG. 6), that is, in the tilting direction of the stacking platform 2, so that the paper will smoothly wind around the negative suction roller 32, or, in other words, the negative suction roller The drum 32 rotates along with the paper, so that the paper is naturally wound on the negative suction roller 32 instead of dragging the paper; in this way, the front edge of the paper is mostly wound on the negative suction roller 32, because the paper is The piled portion is reduced, and it enters between the negative suction roller 32 and the paper feed roller 31. The paper pressure bearing 322 on the negative suction roller 32 and the paper feed roller 31 pinch the paper to draw it out and transport it To the bottom (the negative suction hole 320 on the negative suction roller 32 is responsible for sucking paper, and the paper pressure bearing 322 is used to press the paper against the paper feed roller 31. Since the paper pressure bearing 322 can rotate, the negative suction roller 32 goes back and forth When rotating, the paper pressure bearing 322 and the paper feed pressure roller 31 pressing the paper will not cause resistance to the paper); when the paper is transported to the bottom Afterwards, the paper suction transmission mechanism drives the negative suction roller 32 to move on the paper feed pressure roller 31 along the arc surface of the paper feed pressure roller 31 in the upper right corner direction (the direction in FIG. 5), and re-extracts the next sheet of paper.
负吸辊筒32上具有负吸孔320，每送一张纸，负吸孔320吸一次，如果负吸辊筒32只朝一个方向转动的话，负吸辊筒32则需要转一周才完成一次送纸，这样不仅影响送纸效率，而且难以保障送纸的连续性与准确性。因此本发明在机架1上固定安装一个弧形齿条35，而在负吸辊筒32的一端安装负吸辊筒齿轮320，该负吸辊筒齿轮320与弧形齿条35啮合；借助弧形齿条35的反作用力，负吸辊筒32前后移动时，便能实现顺时针转动与逆时针转动。这种转动方式的好处是:如图6所示，负吸辊筒32向左下角移动(堆放平台2所在方向)，负吸辊筒32只顺时针转动180°，配合送纸压轮31的逆时针转动，就将纸张输送到下方，而此过程负吸辊筒32上的负吸孔320也只是吸着纸张转动180°；完成送纸之 后，负吸辊筒32右上角移动，再借助弧形齿条35的反作用力，负吸辊筒32又逆时针转动180°，从而使负吸辊筒32上的负吸孔320重新回到纸堆底部，吸取下一张纸；而送纸压轮31通过动力源的驱动只朝一个方向转动，即如图6中的逆时针方向。通过上述方式，送一张纸，负吸辊筒32只需来回各转动180°，因此显著提高了送纸速度，保证了整个折纸过程的连续性与准确性,而且传动关系也更加简单，结构也更加合理。The negative suction roller 32 has a negative suction hole 320. The negative suction hole 320 sucks once for each sheet of paper. If the negative suction roller 32 only rotates in one direction, the negative suction roller 32 needs to rotate once to complete it once. Paper feeding not only affects the efficiency of paper feeding, but also makes it difficult to guarantee the continuity and accuracy of paper feeding. Therefore, in the present invention, an arc rack 35 is fixedly installed on the machine frame 1, and a negative suction roller gear 320 is installed at one end of the negative suction roller 32, and the negative suction roller gear 320 meshes with the arc rack 35; The reaction force of the arc rack 35 can realize clockwise rotation and counterclockwise rotation when the negative suction roller 32 moves back and forth. The advantage of this type of rotation is: as shown in Figure 6, the negative suction roller 32 moves to the lower left corner (the direction of the stacking platform 2), the negative suction roller 32 only rotates 180 ° clockwise, matching the feed roller 31 Rotate counterclockwise to convey the paper to the bottom, and in this process, the negative suction hole 320 on the negative suction roller 32 only sucks the paper and rotates 180 °; after the paper feed is completed, the upper right corner of the negative suction roller 32 moves, and then the arc Due to the reaction force of the rack 35, the negative suction roller 32 rotates 180 ° counterclockwise, so that the negative suction hole 320 on the negative suction roller 32 returns to the bottom of the paper stack to suck the next sheet of paper; The wheel 31 is driven by the power source to rotate in only one direction, that is, the counterclockwise direction as shown in FIG. 6. In the above way, when feeding a piece of paper, the negative suction roller 32 only needs to rotate 180 ° back and forth, so the paper feeding speed is significantly improved, the continuity and accuracy of the entire folding process are ensured, and the transmission relationship is also simpler and the structure Also more reasonable.
本发明的送纸压轮31的直径大于负吸辊筒32的直径，大直径的送纸压轮31能实现不同速比，更适合输送不同尺寸的纸张，同时能让负吸辊筒32在其表面的运动轨迹更加接近切线，这样纸张能更容易地卷到负吸辊筒32上；另外，堆放平台2的里端位于负吸辊筒32的上方，负吸辊筒32位于堆放平台2里端与负吸辊筒32之间，负吸辊筒32在送纸压轮31上沿着堆放平台2倾斜的方向回来转动。The diameter of the paper feed roller 31 of the present invention is larger than the diameter of the negative suction roller 32. The large-diameter paper feed roller 31 can realize different speed ratios, and is more suitable for conveying paper of different sizes, while allowing the negative suction roller 32 to The trajectory of its surface is closer to the tangent line, so that the paper can be more easily wound onto the negative suction roller 32; in addition, the inner end of the stacking platform 2 is located above the negative suction roller 32, and the negative suction roller 32 is located on the stacking platform 2 Between the inner end and the negative suction roller 32, the negative suction roller 32 rotates back on the paper feed pressure roller 31 in the direction in which the stacking platform 2 is inclined.
负吸辊筒32在送纸压轮31上的移动是由吸纸传动机构驱动的，如图1-3所示，吸纸传动机构包括有传动轴33、传动轮330以及传动摆臂34，传动轮330安装在传动轴33上，传动摆臂34一端铰接在传动轮330上的偏心位置，其另一端与负吸辊筒32铰接。工作时，动力源驱动传动轴33转动，安装在传动轴33上的传动轮330随之转动，由于传动摆臂34一端铰接在传动轮330上的偏心位置，另一端与负吸辊筒32铰接，因此传动摆臂34就带着负吸辊筒32在送纸压轮31上沿送纸压轮31的弧面移动。The movement of the negative suction roller 32 on the paper feed pressure roller 31 is driven by a paper suction transmission mechanism. As shown in FIGS. 1-3, the paper suction transmission mechanism includes a transmission shaft 33, a transmission wheel 330, and a transmission swing arm 34. The transmission wheel 330 is mounted on the transmission shaft 33, one end of the transmission swing arm 34 is hinged at an eccentric position on the transmission wheel 330, and the other end is hinged to the negative suction roller 32. During operation, the power source drives the transmission shaft 33 to rotate, and the transmission wheel 330 mounted on the transmission shaft 33 rotates accordingly. Due to the eccentric position of one end of the transmission swing arm 34 hinged on the transmission wheel 330, the other end is articulated with the negative suction roller 32 Therefore, the transmission swing arm 34 carries the negative suction roller 32 on the paper feed roller 31 to move along the arc surface of the paper feed roller 31.
由于负吸辊筒的一端只有弧形齿条35压着，如果另一端没有任何压着的话，负吸辊筒32来回转动时可能会吊起(如果通过左右两条弧形齿条35压着，那么就很难保证两边弧形齿条35的一致性)，为此，本发明在负吸辊筒32的另一端安装有定位轴承，机架1上安装有定位弧条36，如图1所示，定位轴承就作用在定位弧条36的内弧面上。通过这种结构，能有效防止负吸辊筒32前后来回移动时被吊起，保证负吸辊筒32运动的稳定性。Since only one curved rack 35 is pressed on one end of the negative suction roller, if there is no pressure on the other end, the negative suction roller 32 may be lifted when rotating back and forth (if pressed by the left and right two curved racks 35 , Then it is difficult to ensure the consistency of the arc racks 35 on both sides). Therefore, the present invention is equipped with a positioning bearing on the other end of the negative suction roller 32, and a positioning arc strip 36 is installed on the frame 1, as shown in FIG. 1 As shown, the positioning bearing acts on the inner arc surface of the positioning arc strip 36. With this structure, the negative suction roller 32 can be effectively prevented from being lifted when moving back and forth, and the stability of the movement of the negative suction roller 32 can be ensured.
在纸堆较高的情况下，借负吸辊筒32移动的方式还是有可能无法将纸张抽出，为了保证送纸机构3能正常工作，本发明还设有分离推板37，分离推板37通过连接臂与负吸辊筒32传动连接，分离推板37上连接有导向片371，导向片371滑动设在两块压块372之间，分离推板37与堆放平台2保持同个方向倾斜，分离推板37上设置有与气源相连的吹风孔370，吹风孔370的吹风口对着负吸辊筒32上部或上部以上的位置。分离推板37通过导向片371滑动设在两块压块372之间，负吸辊筒32沿弧形轨迹移动，分离推板37也随负吸辊筒32一起移动(分离推板37的轨迹也为弧线，因此导向片371具有弹性)；当负吸辊筒32吸附住纸张时，吹风孔370对着负吸辊筒32上部或上部以上的位置吹风，吹风孔370吹出的风分离了负吸辊筒32吸附住的纸张与上部纸张，通过这种方式，进一步确保纸张能被 顺利抽去。In the case of a high paper stack, it may still be impossible to pull out the paper by the way of the negative suction roller 32 moving. In order to ensure that the paper feeding mechanism 3 can work normally, the present invention also provides a separation push plate 37, a separation push plate 37 The connecting arm is driven and connected to the negative suction roller 32, and a guide piece 371 is connected to the separation push plate 37. The guide piece 371 is slidably disposed between the two pressing blocks 372, and the separation push plate 37 and the stacking platform 2 are kept inclined in the same direction The separation push plate 37 is provided with a blow hole 370 connected to the air source. The blow hole of the blow hole 370 faces the upper part of the negative suction roller 32 or above. The separation push plate 37 is slidably provided between the two pressing blocks 372 through the guide piece 371, the negative suction roller 32 moves along an arc-shaped trajectory, and the separation push plate 37 also moves with the negative suction roller 32 (the trajectory of the separation push plate 37) It is also an arc, so the guide piece 371 has elasticity); when the negative suction roller 32 attracts the paper, the blowing hole 370 blows at the position above or above the negative suction roller 32, and the wind blown by the blowing hole 370 separates The paper sucked by the negative suction roller 32 and the upper paper, in this way, further ensure that the paper can be pulled out smoothly.
由于纸张的前边缘可能存在翘起的情况，负吸辊筒32无法将纸张的前边缘全部吸住，为了解决这一问题，本发明在分离推板37的上方设置有前挡板38，前挡板38与堆放平台2保持垂直，前挡板38上设置有与气源相连的喷气孔380，喷气孔380的喷气口对着负吸辊筒32的上部。该前挡板38不仅能用于对纸堆前边的定位，而且其上的喷气孔380与气源相通后可以将纸张的前边缘向下吹，这样纸张的前边就能确保完全贴附在负吸辊筒32上。Because the front edge of the paper may be warped, the negative suction roller 32 cannot suck all the front edge of the paper. In order to solve this problem, the present invention is provided with a front baffle 38 above the separation push plate 37. The baffle 38 is kept perpendicular to the stacking platform 2, and the front baffle 38 is provided with an air injection hole 380 connected to the air source, and the air injection port of the air injection hole 380 faces the upper portion of the negative suction roller 32. The front baffle 38 can not only be used to position the front edge of the paper stack, but the air hole 380 on it can communicate with the air source to blow down the front edge of the paper, so that the front edge of the paper can be completely attached to the negative On the suction roller 32.
如图3所示，本发明在传动轴上设有偏心平衡块331，偏心平衡块331的重心与传动轮330的偏心连接点分别位于以传动轴轴心为中心的两侧。偏心平衡块331用于补偿传动轴33带动负吸辊筒32作偏心运动，在500页/MIN折页时，使折页机能平稳顺畅飞速折页。As shown in FIG. 3, the present invention is provided with an eccentric balance weight 331 on the transmission shaft. The center of gravity of the eccentric balance weight 331 and the eccentric connection point of the transmission wheel 330 are located on both sides centered on the transmission shaft axis. The eccentric balance weight 331 is used to compensate for the eccentric movement of the negative suction roller 32 driven by the transmission shaft 33, and enables the folding machine to smoothly and smoothly fold at 500 pages / MIN.
如图4所示，为了达到不同速比，以实现不同尺寸纸张的最快折页，本发明在机架1上安装有主动轴65与从动轴66，从动轴65与负吸辊筒32及送纸压轮31传动连接，主动轴65上设有左主动同步轮60与右主动同步轮62，从动轴66上设有左被动同步轮61与右被动同步轮63，左主动同步轮60与左被动同步轮61通过第一同步带连接，右主动同步轮62与右被动同步轮63通过第二同步带连接。每两组合速比可同时安装在主动轴与从动轴，纸张格式区域变化只需拨动拨挡装置64即可完成，组合丰富，切换简便，用途广泛。As shown in FIG. 4, in order to achieve different speed ratios and achieve the fastest folding of papers of different sizes, the present invention is equipped with a driving shaft 65 and a driven shaft 66 on the frame 1, the driven shaft 65 and the negative suction roller 32 and the paper feed pressure roller 31 are driven and connected. The driving shaft 65 is provided with a left driving synchronous wheel 60 and a right driving synchronous wheel 62, and the driven shaft 66 is provided with a left passive synchronous wheel 61 and a right passive synchronous wheel 63, and the left driving synchronous The wheel 60 and the left passive synchronous wheel 61 are connected by a first synchronous belt, and the right active synchronous wheel 62 and the right passive synchronous wheel 63 are connected by a second synchronous belt. Every two combined speed ratios can be installed on the driving shaft and the driven shaft at the same time.
