具体实施方式detailed description
如图1-2所示，一种橡胶定长自动裁断机，包括送料输送带1、出料输送带2及中间的裁切机构3，所述送料输送带1和出料输送带2分别通过独立的送料电机4和出料电机5驱动，送料电机4和出料电机5均为同步电机，通过同步电机精确控制送料转子的运转周长，从而保证剪切长度的准确性，所述裁切机构3包括剪切刀片6，剪切刀片6由固定下刀片和活动上刀片组成，活动上刀片安装在滑轨内，活动上刀片两侧通过摇杆与凸轮7铰接，构成曲柄滑块机构，凸轮7通过旋转气缸8带动。在剪切刀片6上方的固定架上安装有两个红外探头9，红外探头9用于检测输送带上有无胶片，这样方便快速启动剪切；红外探头9用于安全保护，当红外探头检测到有物品靠近防护网附近时，剪切刀片将停止动作，可以有效避免生产过程中意外事故的出现。由于上下刀片在对切过程中直接接触容易导致磨损变钝，因此，可在下固定刀片底端安装弹性橡胶片，弹性橡胶片两端设有长度为0.5cm-1cm的弹性凸起，这样可在剪切过程中实现一定的缓冲，减少直接正切过程中，上刀片由于位置偏移或电机震动导致刀片对切磨损变钝损坏的问题。As shown in Figure 1-2, a rubber fixed-length automatic cutting machine includes a feeding conveyor belt 1, a discharging conveyor belt 2 and a cutting mechanism 3 in the middle, and the feeding conveyor belt 1 and the discharging conveyor belt 2 respectively pass through Driven by independent feeding motor 4 and discharging motor 5, both feeding motor 4 and discharging motor 5 are synchronous motors, and the running circumference of the feeding rotor is precisely controlled by the synchronous motor, thereby ensuring the accuracy of the cutting length. The mechanism 3 includes a shearing blade 6, the shearing blade 6 is composed of a fixed lower blade and a movable upper blade, the movable upper blade is installed in the slide rail, and the two sides of the movable upper blade are hinged with the cam 7 through a rocker to form a crank slider mechanism, Cam 7 is driven by rotating cylinder 8. Two infrared probes 9 are installed on the fixed frame above the shearing blade 6, and the infrared probes 9 are used to detect whether there is a film on the conveyor belt, so that it is convenient to start cutting quickly; the infrared probes 9 are used for safety protection. When something is close to the protective net, the shearing blade will stop, which can effectively avoid accidents during the production process. Since the upper and lower blades are in direct contact with each other during the cutting process, it is easy to cause wear and become blunt. Therefore, an elastic rubber sheet can be installed at the bottom of the lower fixed blade. The two ends of the elastic rubber sheet are provided with elastic protrusions with a length of 0.5cm-1cm. A certain buffer is realized during the cutting process, which reduces the problem of the upper blade being worn, blunt and damaged due to position deviation or motor vibration in the direct tangential cutting process.
两个红外探头9、送料电机4、出料电机5及旋转气缸8均通过PLC控制器14控制启动。在工作时，送料电机4和出料电机5均带动输送带运行，当送料电机4带动胶片运动到合适长度后，PLC控制器控制送料电机4停止（或降低速度），并同时通过电磁伺服阀控制旋转气缸8带动活动上刀片下移进行剪切，剪切完成后，送料输送带1迅速反转将输送胶片退后，避免胶片粘刀对胶片向前输送的阻碍，同时单向送料导辊及时阻止胶片后退的重力滑落，防止裁切长度的不稳定；出料输送带2随即将胶片带走，输送带2的速度大于输送带1的速度，以保证裁断的胶片不阻碍后面胶片的输送，这样既可保证胶片的有效裁断，同时解决了裁断的橡胶胶片粘刀对连续生产不利因素的困扰。The two infrared probes 9 , the feeding motor 4 , the discharging motor 5 and the rotary cylinder 8 are all controlled and started by the PLC controller 14 . When working, both the feeding motor 4 and the discharging motor 5 drive the conveyor belt to run. When the feeding motor 4 drives the film to move to a suitable length, the PLC controller controls the feeding motor 4 to stop (or reduce the speed), and at the same time through the electromagnetic servo valve. Control the rotating cylinder 8 to drive the movable upper blade to move down for cutting. After the cutting is completed, the feeding conveyor belt 1 will quickly reverse to move the film back, so as to avoid the obstruction of the film from sticking to the knife. At the same time, the one-way feeding guide roller Timely prevent the film from falling due to gravity to prevent the instability of the cutting length; the discharge conveyor belt 2 will take the film away immediately, and the speed of the conveyor belt 2 is greater than the speed of the conveyor belt 1, so as to ensure that the cut film does not hinder the conveyance of the following film , which can not only ensure the effective cutting of the film, but also solve the trouble of the unfavorable factors of continuous production caused by the cut rubber film sticking to the knife.
所述送料输送带1两侧安装有急停安全开关10。当胶片没有时，通过红外线检测后，使急停安全开关动作，送料电机4停止运转，从而避免后面空切带来对刀片的损伤。An emergency stop safety switch 10 is installed on both sides of the feeding conveyor belt 1 . When there is no film, after the infrared detection, the emergency stop safety switch is activated, and the feeding motor 4 stops running, thereby avoiding the damage to the blade caused by the air cutting in the back.
所述送料输送带1上安装有多个压料辊11。所述压料辊11两端设有Z型调节杆12，Z型调节杆12与固定套筒13螺纹连接，并通过把手调节。由此可根据不同厚度的胶片，旋转Z型调节杆12，调节压料辊与工作台之间的间距，从而有效调整松紧度。A plurality of nip rollers 11 are installed on the feeding conveyor belt 1 . Both ends of the nip roller 11 are provided with a Z-shaped adjusting rod 12, which is screwed to a fixed sleeve 13 and adjusted by a handle. Thereby, the Z-shaped adjusting rod 12 can be rotated according to films of different thicknesses to adjust the distance between the nip roller and the worktable, thereby effectively adjusting the tightness.
