本发明的有益效果是：The beneficial effects of the invention are:
1、装料省力：利用一个供料驱动电机驱动摆动机构偏转，装料时将摆臂降到低位，直接将原料卷滚动到摆臂的前端，并将原料轴两端的滚轮滚动放在摆动机构的凹槽内，然后摆动机构向上转动直至原料卷靠在胶辊上，完成上料。非常省力，省去了装料机械，节约了成本和占地。1. Load and labor saving: use a feeding drive motor to drive the swinging mechanism to deflect. When loading, lower the swing arm to the low position, directly roll the raw material roll to the front end of the swing arm, and roll the roller at both ends of the raw material shaft to the swinging mechanism. In the groove, the swing mechanism is rotated upward until the material roll is pressed against the rubber roller to complete the loading. Very labor-saving, eliminating the need for loading machinery, saving costs and land.
2、能耗低：原料卷升到高位后，原料轴上的滚轮与摆动机构一起倒向胶辊，使得原料卷（依靠自身的重量）与胶辊紧密接触，胶辊转动并利用摩擦力带动原料卷转动，同时原料卷上的原料膜在由两个胶辊夹紧向下拉动，也会拉动原料卷转动，这样，原料卷在整个生产过程中就不需要专门的动力装置驱动，节约了能源和生产成本。另外，在停止运转或中间停顿时，胶辊对原料卷具有刹车的作用，防止原料卷在惯性的作用下继续转动导致原料膜重叠褶皱。2. Low energy consumption: After the raw material coil is raised to a high position, the roller on the raw material shaft and the swinging mechanism are turned down to the rubber roller, so that the raw material roll (depending on its own weight) is in close contact with the rubber roller, and the rubber roller rotates and is driven by friction. The raw material roll rotates, and the raw material film on the raw material roll is pulled down by the two rubber rollers, which also pulls the raw material roll to rotate, so that the raw material roll does not need a special power device drive during the whole production process, saving Energy and production costs. In addition, when the operation is stopped or the intermediate pauses, the rubber roller has a function of braking the raw material roll, and the raw material roll is prevented from continuing to rotate under the action of inertia, resulting in overlapping wrinkles of the raw material film.
3、简化了结构：由于原料卷与胶辊直接接触，原料膜与胶辊同步转动，两者之间不存在原料膜重叠卷曲的问题，这就省去了伸展薄膜的机构，简化了结构，降低了制造成本。3. Simplified structure: Since the raw material roll is in direct contact with the rubber roller, the raw material film and the rubber roller rotate synchronously, and there is no problem that the raw material film overlaps and curls between the two, which eliminates the mechanism for stretching the film and simplifies the structure. Reduced manufacturing costs.
4、通过较宽的凹槽和设在凹槽两侧的位置开关，再配合红外传感器和摆臂上限位开关可以控制摆臂随着原料的减少逐步向前摆动，避免摆动幅度过大直接使原料卷冲击胶辊对胶辊造成损伤。4. Through the wide groove and the position switch on both sides of the groove, and the infrared sensor and the swing arm upper limit switch can be used to control the swing arm to gradually swing forward with the decrease of the raw material, so as to avoid the swing amplitude being too large. The raw material roll impacts the rubber roller to cause damage to the rubber roller.

The front side (as shown in FIG. 16); when the swing arm 70 continues to swing forward until the material roll 18 abuts on the rubber roller 13 (as shown in FIG. 17), the signal of the infrared sensor 23 is stopped by the controller control swing arm 70. Rotating, the signal of the infrared sensor 23 also starts the front position switch 24 and the rear position switch 25 to start working; as the bag making machine operates, the material roll 18 is gradually reduced, and the roller 10 at both ends of the raw material shaft 17 gradually faces the front of the groove 110. The side moves until the front position switch 24 is triggered, and the signal output from the front position switch 24 swings the swing arm 70 forward by the controller. When the rear position switch 25 comes into contact with the roller 10, the signal is triggered, and the signal stops the swing arm 70 through the controller. Swing, repeat so until the raw material 18 basically run out, when the trigger arm 70 swing limit switch 28, the front 24 and the rear working position of the switch position of the switch arm 25 of the limit switch signal 28 is stopped by the controller. At this point, the entire feeding process is completed.
当原料用完后，通过控制器驱动摆臂70反向复位，摆臂70最后在摆臂下限位开关26的信号控制器下停止在下位。安装原料卷18后进行下一次的送料过程。When the raw material is used up, the swing arm 70 is reversely reset by the controller, and the swing arm 70 is finally stopped at the lower position under the signal controller of the swing arm lower limit switch 26. After the raw material roll 18 is installed, the next feeding process is performed.
