[0014] Figure 2 The structure diagram of the utility model is set in the whole machine; DETAILED DESCRIPTION

[0015] As shown in the figure, the utility model discloses a kind of material conveying mechanism of packaging machine, including front conveying belt 1, push block 2 is arranged in front conveying belt 1, and transition conveying belt 22 is connected in the discharge end of front conveying belt 1, the conveying path of transition conveying belt 22 is provided with the inductor 16 that can detect material, inductor 16 can feedback information to controller, and controller can control the action of packaging base material traction assembly 5 according to the information of inductor 16 feedback.The packaging base material traction assembly 5 is the traction wheel of upper and lower cooperation, and traction wheel is connected with corresponding drive motor transmission, it belongs to the common structure on market, so it will not be described again.

[0016] Further, the transition conveying belt 22 passes through a lower power wheel 23 on a lower power shaft 21, the lower power shaft 21 is in transmission connection with the driving motor 9, an activity frame 14 is arranged above the transition conveying belt 22, the activity frame 14 is provided with an upper power shaft 18, the lower power shaft 21 is provided with a first gear 20, the upper power shaft 18 is provided with a second gear 19 meshing with the first gear 20, and a first swing arm 12 is further arranged, one end of the first swing arm 12 is hinged to the lower power shaft 21, and the other end of the first swing arm 12 is hinged to the upper power shaft 18, the material pressing belt 3 passes through an upper power wheel 17 on the upper power shaft 18, and the transition conveying belt and the material pressing belt can cooperate to compress and convey the material. Since the two ends of the first swing arm 12 are respectively hinged to the upper and lower power shafts, when the first swing arm 12 swings, the first and second gears can still maintain normal meshing transmission state, ensuring that the upper and lower power shafts can drive the material pressing belt and the transition conveying belt to act. With the above structure, the material is pushed to the transition conveying belt and the material pressing belt for compression and conveying, and according to the thickness change of the material, the activity frame 14 is extruded and the first swing arm 12 swings, so that the height of the activity frame 14 is self-adaptively adjusted, ensuring that the material of different thicknesses can be compressed and conveyed by the transition conveying belt 22 and the material pressing belt 3 to the compression roller assembly 25.

[0017] Further, the transition conveying belt 22 is provided with a material passing platform 24, and the material passing platform 24 is provided with a sensing groove 15 corresponding to the inductor 16. With the above structure, when the material passes through the sensing groove 15, the sensing groove 15 is shielded, at this time the inductor 16 feeds back information indicating that the material has passed, if there is no material passing through the sensing groove 15, the inductor 16 continuously feeds back another information indicating that there is no material passing. In addition, when the transition conveying belt 22 in the application adopts a narrow belt, the material is wider than the transition conveying belt 22, and the material passing platform 24 is arranged to locally support the material, ensuring that the material can be conveyed flatly and stably, when the transition conveying belt 22 in the application adopts a wide belt, it is sufficient to support the material, and then the material passing platform can not be arranged.

[0018] Further, the output end of the driving motor 9 is connected with the first synchronous wheel 11, the first synchronous wheel 11 is in transmission with the second synchronous wheel through the synchronous belt 10, and the second synchronous wheel is connected with the lower power shaft 21. With the above structure, by controlling the driving motor 9 to act, and through the synchronous belt transmission group to drive, the lower power shaft 21 can be driven to rotate; of course, in addition to the synchronous wheel transmission group structure, a chain wheel and chain group can also be used for transmission.

[0019] Furthermore, the device further includes a second swing arm 13, one end of which is hinged to the base, and the other end of which is hinged to the movable frame 14. The second swing arm 13 remains parallel to the first swing arm 12. This structure allows the first and second swing arms to swing simultaneously, thereby guiding the movement of the movable frame 14 and further improving the stability and reliability of the movement of the movable frame 14.

[0020] Furthermore, at least two transition conveyor belts 22 and pressing belts 3 are provided at intervals, ensuring that multiple parts of the material can be pressed and conveyed, effectively improving the stability of material transportation.

[0021] The working principle of the present invention is as follows: the material is first pushed by the push block 2 on the front conveyor belt 1, and then transported to the transition conveyor belt 22, and transferred through the transition conveyor belt 22, so that the material can be transported smoothly. When the material passes through the sensor 16, the sensor 16 will feedback information to the controller. The controller controls the action of the packaging substrate traction component 5 according to the received information, driving the packaging substrate on the upper packaging substrate unwinding shaft 4 and the lower packaging substrate unwinding shaft 7 to unwind. Subsequently, the material and the packaging substrate are sent to the pressing roller component 25 together, so that the material and the upper and lower packaging substrates are pressed together, and then heat-sealed by the heat-sealing rolling cutting component 6 and cut into single shapes and sent out through the discharge conveyor belt 8.

[0022] The structure of the present invention can connect and transfer materials through the transition conveyor belt by additionally setting up a transition conveyor belt, thereby avoiding deformation or wrinkles of the materials caused by the pushing of the push block, ensuring the smooth transportation of the materials. At the same time, a sensor for sensing the materials is set to ensure that only after the materials are smoothly transported to the specified position, the packaging substrate traction component is controlled to perform adaptive actions accordingly, so that the materials can be accurately delivered to the packaging substrate for packaging processing.
