[0037] Please also read Figures 1 to 5 Now, a material transfer device for a packaging machine provided in an embodiment of the present application is described. The material transfer device for a packaging machine includes a frame 101, a conveyor belt 102, a suspension 103 and a material taking component. Among them:

[0038] Several conveyor belts 102 are arranged in parallel on the frame 101. In this embodiment, the conveyor belts 102 can be selected as the grid type conveyor belts 102 commonly used in the art. The suspension 103 is erected above the conveyor belts 102 through the support tube 104 connected to the frame 101 and forms an annular guide groove 105 spanning all the conveyor belts 102. The suspension 103 has several conveyor belts 102 arranged in parallel along the conveying direction of the conveyor belts 102, and each annular guide groove 105 corresponds to a conveyor belt 102 to form a lower gripping position 106 that sinks along the height direction of the suspension 103. The material picking assembly includes a slider 107 that is slidably connected to the annular guide groove 105 and can be provided with a sliding guide by the annular guide groove 105, and a suction cup 108 connected to the slider 107 and used to suck materials. The material picking assembly also includes a driving mechanism that is transmission-connected to the slider 107 and used to drive the slider 107 to move in the annular guide groove 105.

[0039] According to the above structure provided in the present embodiment, in the material transferring device for the packaging machine line provided in the present embodiment, a number of suspensions 103 corresponding to the number of conveyor belts 102 are arranged across the top of the conveyor belts 102, and each suspension 103 forms an annular guide groove 105 spanning all the conveyor belts 102, and each annular guide groove 105 corresponds to a conveyor belt 102 to form a lower gripping position 106 that sinks along the height direction of the suspension 103. In this way, when the slider 107 in the material picking assembly moves in the annular guide groove 105, the suction cup 108 connected to the slider 107 can descend along the height direction of the suspension 103 at the lower gripping position 106 set on the annular guide groove 105 and absorb the material transported on the conveyor belt 102. In the process of the slider 107 subsequently moving along the annular guide groove 105, multiple groups of suction cups 108 can transfer the materials transported on multiple groups of conveyor belts 102 to the same conveyor belt 102 or complete the stacking of materials. Therefore, the material moving device for the packaging machine line provided in this embodiment can complete the rapid transfer of materials on multiple groups of conveyor belts 102 only by setting multiple groups of suspensions 103 and the material picking assembly set on the suspension 103, which significantly reduces the manufacturing cost of the material moving device and is far superior to the prior art.

[0040] In another embodiment provided in this application, please refer to Figures 1 to 5, the cross direction of the annular guide groove 105 is inclined to the conveying direction of the conveyor belt 102, and the component speed of the moving speed of the slider 107 in the annular guide groove 105 in the conveying direction of the conveyor belt 102 is equal to the conveying speed of the conveyor belt 102. According to the above structure provided in this embodiment, when the component speed of the moving speed of the slider 107 in the conveying direction of the conveyor belt 102 is equal to the conveying speed of the conveyor belt 102, the relative stillness of the suction cup 108 and the conveyor belt 102 can be achieved, that is, when the slider 107 drives the suction cup 108 to the lowest position of the lower gripping position 106 and the mouth surface of the suction cup 108 abuts against the material, the material and the suction cup 108 are relatively still, ensuring that the material is firmly sucked under dynamic conditions, and then the slider 107 rises to lift the material away from the conveyor belt 102 and transport it to the set position along with the annular guide groove 105, so that it is more convenient for the suction cup 108 to absorb the material from the conveyor belt 102, which is conducive to significantly improving the material picking stability of the material transfer device for packaging machine connection provided in this embodiment.

[0041] In another embodiment provided in this application, please refer to Figures 1 to 5 , the annular guide groove 105 is in a "V" shape at the lower gripping position 106.

According to the above structure provided in the present embodiment, the servo motor 113 can drive the annular chain 111 through the active sprocket 109 and the passive sprocket 110. The guide rod 112 driven by the annular chain 111 can move around the suspension 103 and drive the slider 107 to move in the annular guide groove 105. It can not only stably drive the slider 107, but also because the guide rod 112 is slidably connected to the slider 107, it can also provide guidance for the movement of the slider 107 in the height direction relative to the suspension 103, thereby helping to further improve the material picking stability of the material moving device for the packaging machine line provided in the present embodiment.
