为避免切割好的物料被风吹走，在步骤3)中，所述传输带输送物料时，通过吸风装置将传输带上的物料吸附住。In order to prevent the cut materials from being blown away by the wind, in step 3), when the conveyor belt conveys the materials, the materials on the conveyor belt are adsorbed by the air suction device.
为避免被吹风装置从放纸板上吹落，在步骤2)中，所述放纸板停止移动时，与放纸板相邻的弹性压板转动到最上一张物料的上方。In order to avoid being blown off by the air blowing device from the paperboard, in step 2), when the paperboard stops moving, the elastic pressing plate adjacent to the paperboard rotates above the top material.
为进一步确保一次仅吸附一个物料，在步骤3)中，所述放纸板向上移动一个物料的高度后，所述横梁组件先向后移动一定距离，使得被吸附的物料经过弹性压板进一步刮剥分离，然后横梁组件再向前移动。To further ensure that only one material is adsorbed at a time, in step 3), after the paperboard is moved upward by one material height, the beam assembly first moves backward a certain distance, so that the adsorbed material is further scraped and separated by the elastic pressure plate , And then the beam assembly moves forward again.

送纸组件2包括放纸板21，位于放纸板21前侧相邻处的吹风装置22和支柱23，以及设置在放纸板21上的物料定位组件。第一支架11和第二支架12之间、位于放纸板21前侧、靠近顶部的位置连接有支撑杆221，上述的吹风装置22和支柱23设置在支撑杆221上。吹风装置22上开设有吹风口，支柱23在纵向上延伸，其顶端设有弹性压板231，用于压放纸板21上的物料100(图中未示出放纸板21上待切割的物料100)。The paper feeding assembly 2 includes a paper board 21, a blower 22 and a pillar 23 located adjacent to the front side of the paper board 21, and a material positioning assembly provided on the paper board 21. A support rod 221 is connected between the first bracket 11 and the second bracket 12 on the front side of the paper board 21 and near the top. The above-mentioned blowing device 22 and the support 23 are provided on the support rod 221. The blowing device 22 is provided with a blowing port, the pillar 23 extends in the longitudinal direction, and an elastic pressing plate 231 is provided at the top thereof for pressing and releasing the material 100 on the cardboard 21 (the material 100 to be cut on the cardboard 21 is not shown in the figure) .
物料定位组件包括可相对放纸板21滑动的第一侧挡板241、第二侧挡板242、以及后挡板243。第一侧挡板241、第二侧挡板242和第三侧挡板243均能在放纸板21上滑动。第一侧挡板241靠近第一支架11和第二支架12中的其中一个，第二侧挡板242靠 近第一支架11和第二支架12中的另一个，而后挡板243在放纸板21上位于第一侧挡板241和第二侧挡板242的后部。第一侧挡板241和第二侧挡板242均在前、后方向上延伸，而后挡板243在第一支架11和第二支架12之间延伸。The material positioning assembly includes a first side fence 241, a second side fence 242, and a rear fence 243 that can slide relative to the paper board 21. The first side baffle 241, the second side baffle 242, and the third side baffle 243 can all slide on the paper board 21. The first side fence 241 is close to one of the first bracket 11 and the second bracket 12, the second side fence 242 is close to the other of the first bracket 11 and the second bracket 12, and the rear fence 243 is placed on the cardboard 21 The upper portion is located at the rear of the first side fence 241 and the second side fence 242. The first side fence 241 and the second side fence 242 both extend in the front and rear directions, and the rear fence 243 extends between the first bracket 11 and the second bracket 12.
上述的三个挡板通过吸铁石的吸附作用(放纸板21由铁磁性的金属制成)而吸附在放纸板21上，当将物料100放置到放纸板21上后，可将各挡板从放纸板21上取下，并定位在物料100的边缘处，从而实现物料100在放纸板21上的定位。The three baffles mentioned above are adsorbed on the paperboard 21 through the adsorption of the iron-absorbing stone (the paperboard 21 is made of ferromagnetic metal). When the material 100 is placed on the paperboard 21, each baffle can be removed from the The cardboard 21 is removed and positioned at the edge of the material 100, so as to achieve the positioning of the material 100 on the cardboard 21.
上述的吹风装置22、支柱23、弹性压板231和物料定位组件与现有技术的相同，可参见背景技术中提及的本申请人的申请号为201810227974.1的中国专利，在此不再赘述。The above-mentioned blower device 22, pillar 23, elastic pressing plate 231 and material positioning assembly are the same as those in the prior art, and reference can be made to the Chinese patent of the applicant with the application number 201810227974.1 mentioned in the background art, which will not be repeated here.
放纸板21的上表面可嵌入有感应器25，如红外收发传感器，用于感应放纸板21上是否放有待切割的物料100。当放纸板21上放置物料100时，感应器25发射出的红外线受阻反射，从而能接收到反射的红外线而判断此时放纸板21上放置有物料100，否则则代表放纸板21上无物料100。第一支架11和第二支架12上还分别设置有上限位传感器252和下限位传感器253，其中，上限位传感器252具有两个、分别设置在第一支架11和第二支架12上并且位置对应，下限位传感器253具有两个、分别设置在第一支架11和第二支架12上并且位置对应。上限位传感器252和下限位传感器253原理相同，均是其中一个为红外发射器，另一个为红外接收器，当红外发射器发射出的红外线被挡住使得红外接收器无法接收到红外线时，判断放纸板21移动到上限位或下限位，而控制放纸板21停止运动，防止放纸板21超过极限位置。A sensor 25, such as an infrared transceiving sensor, may be embedded on the upper surface of the paperboard 21 for sensing whether the material 100 to be cut is placed on the paperboard 21. When the material 100 is placed on the cardboard 21, the infrared emitted by the sensor 25 is blocked and reflected, so that the reflected infrared can be received and it is judged that the material 100 is placed on the cardboard 21 at this time, otherwise it means that there is no material 100 on the cardboard 21 . The first bracket 11 and the second bracket 12 are also provided with an upper limit sensor 252 and a lower limit sensor 253 respectively, wherein the upper limit sensor 252 has two, which are respectively disposed on the first bracket 11 and the second bracket 12 and correspond in position There are two lower limit sensors 253, which are respectively disposed on the first bracket 11 and the second bracket 12 and correspond in position. The upper limit sensor 252 and the lower limit sensor 253 have the same principle, one of which is an infrared transmitter and the other is an infrared receiver. When the infrared emitted by the infrared transmitter is blocked so that the infrared receiver cannot receive infrared, it is judged to be placed. The paperboard 21 moves to the upper limit or the lower limit, and the paperboard 21 is controlled to stop moving to prevent the paperboard 21 from exceeding the limit position.
为驱动放纸板21升降，放纸板21的下方设置有电动推杆26，电动推杆26固定在第一支架11和第二支架12之间。电动推杆26的输出端与放纸板21的底部连接，从而可驱动放纸板21升降。这种驱动方式，结构更简单、成本更低、更可靠、能够减少故障率、具有更高的稳定性，此外，突然断电后不会突然下落，更加安全。In order to drive the paperboard 21 to move up and down, an electric push rod 26 is provided below the paperboard 21, and the electric push rod 26 is fixed between the first bracket 11 and the second bracket 12. The output end of the electric push rod 26 is connected to the bottom of the cardboard discharger 21, so that the cardboard discharger 21 can be driven to move up and down. This driving method has a simpler structure, lower cost, more reliability, can reduce the failure rate, and has higher stability. In addition, it will not fall suddenly after a sudden power failure and is safer.
送纸组件2还包括传输组件27和横梁组件28，上述的机头3设置在横梁组件28上，可以随横梁组件28前、后移动，并且相对横梁组件28在第一支架11和第二支架12之间作直线运动，将在下文详述。传输组件27设置在横梁组件28的下方、并且位于吹风装置22的前侧。传输组件27和横梁组件28可独立地动作，与现有技术相同。The paper feeding assembly 2 further includes a conveying assembly 27 and a beam assembly 28.

The reverse blowing device 275 sucks air from below the conveyor belt 271 through the suction device 2751 to form a negative pressure to suck the material 100 on the conveyor belt 271. Since the transmission belt 271 has good air permeability, the normal operation of the anti-blowing device 275 can be ensured.
第一传动装置还包括第一齿形皮带276和第一皮带轮277，第一驱动装置272和第一皮带轮277相邻设置，第一皮带轮277设置在其中一个第一传输滚筒273(在本实施例中，为后侧的第一传输滚筒273)的端部、并且两者同轴连接。第一齿形皮带276绕设在第一驱动装置272的输出轴和第一皮带轮277上，以便当第一驱动装置272运转时，其输出轴可通过第一齿形皮带276带动第一皮带轮277转动，进而带动该第一传输滚筒273转动，从而带动传输带271动作，进而带动其余的第一传输滚筒273和第二传输滚筒274转动，由此实现传输带271的往复动作。The first transmission device further includes a first toothed belt 276 and a first pulley 277, the first driving device 272 and the first pulley 277 are disposed adjacent to each other, the first pulley 277 is disposed on one of the first transmission rollers 273 (in this embodiment The middle is the end of the first transfer roller 273) on the rear side, and the two are coaxially connected.

3)当前最上方的物料100被吸在吸盘291上，放纸板21向上移动一个物料100的高度，横梁组件28向后移动一定距离，使得被吸附的物料100经过弹性压板231进一步刮剥分离，然后横梁组件28向前侧移动到程序设定的位置(此时传输带271处于静止状态)，吸盘291松开而将物料100放置在传输带271上，通过反吹风装置275将传输带271上的物料100平整吸附使其不被微风等外力移动，横梁组件28上的机头3从横梁组件28的一端向横梁组件28的中部移动，机头3上刀具按给定路径切割或按压物料100；3) The current top material 100 is sucked on the suction cup 291, and the cardboard 21 is moved upward by the height of the material 100, and the beam assembly 28 is moved backward a certain distance, so that the adsorbed material 100 passes through the elastic pressure plate 231 to further scrape and separate. Then the beam assembly 28 moves to the programmed position (at this time, the conveyor belt 271 is at rest), the suction cup 291 is released and the material 100 is placed on the conveyor belt 271, and the conveyor belt 271 is placed on the conveyor belt 271 by the reverse blower 275 The material 100 is absorbed flat so that it will not be moved by external forces such as breeze. The head 3 on the beam assembly 28 moves from one end of the beam assembly 28 to the middle of the beam assembly 28. The cutter on the head 3 cuts or presses the material 100 according to a given path ;
4)当物料100切割完毕后机头3复位，传输带271向前侧移动程序设定的距离后停止，将传输带271上切割好的物料100通过收料斗41滑到收料支架42上，同时横梁组件28向后移动，再次通过吸盘291吸取一个当前最上方的物料100进行下一次物料100切割或按压动作，如此反复；4) After the material 100 is cut, the machine head 3 is reset, and the conveyor belt 271 moves forward to the distance set by the program.
