[0002] A packaging machine is a type of machine that packages products, playing a role in protection and aesthetics. Packaging machines are mainly divided into assembly line-style integrated production packaging and product peripheral packaging equipment. The designed and installed automatic control packaging system has improved the product quality and production efficiency of the packaging machinery industry. Among them, the conveying device, as a core component of the packaging machine, is responsible for smoothly and efficiently conveying the products to be packaged from the upstream process to the packaging station.

Detailed Embodiment

[0019] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0020] An embodiment of the present application discloses a conveying device for a product packaging machine. Refer to Figures 1-4 , a conveying device for a product packaging machine, comprising a frame 1, an outer wall of the frame 1 is provided with a product conveying assembly, an outer wall of the frame 1 is fixedly connected with a bracket 4, an outer groove 5 is formed in an outer wall of the bracket 4, a bidirectional lead screw 6 is rotatably connected to an outer wall of the outer groove 5, a rotating handle 9 is rotatably connected to a side outer wall of the bracket 4, and the rotating handle 9 is fixedly connected to the bidirectional lead screw 6. By rotating the rotating handle 9, it is convenient to drive the bidirectional lead screw 6 to rotate. At the same time, the thread directions on both sides of the bidirectional lead screw 6 are opposite, and two driving rods 7 are symmetrically thread sleeved on outer walls of both sides of the bidirectional lead screw 6. Guide rods 8 are fixedly connected to outer walls of the two driving rods 7. By rotating the bidirectional lead screw 6, the bidirectional lead screw 6 drives the two driving rods 7 on both sides to move towards each other or move in the opposite direction, thereby adjusting the distance between the two guide rods 8 to adapt to the size of the packaged product. The packaged product is guided by the two guide rods 8. Two extension frames 10 are fixedly connected to an outer wall of the frame 1 on one side of the bracket 4. Slide rods 11 are fixedly connected to outer walls of the two extension frames 10. A sliding seat 17 is slidably connected to an outer wall of the slide rod 11. Connection frames 12 are fixedly connected to outer walls of the sliding seat 17. Adjusting rods 13 are fixedly connected to outer walls of the connection frames 12. By sliding and adjusting the sliding seat 17 to move along the slide rod 11, the sliding seat 17 adjusts the adjusting rod 13 through the connection frame 12, so that the adjusting rod 13 is parallel to one side of the guide rod 8, thereby centering and limiting the placement of the packaged product by the two adjusting rods 13 on both sides, facilitating subsequent packaging of the product.

[0021] The product conveying assembly includes a conveyor belt device 2, the conveyor belt device 2 is installed between the frames 1, the conveyor belt device 2 includes a conveyor belt and a transmission mechanism, and the two adjusting rods 13 and the two guide rods 8 are both close to a surface of the conveyor belt device 2. A driving motor 3 for driving the conveyor belt device 2 to operate is provided on a side outer wall of the frame 1. By starting the driving motor 3 through an external power source, the driving motor 3 drives the conveyor belt device 2 to operate.

[0022] The outer wall of the sliding seat 17 is slidably connected with a pull rod 18. A connecting plate 22 is fixedly connected to the outer wall of the pull rod 18. A resisting block 20 is fixedly connected to the outer wall of the connecting plate 22. The resisting block 20 slidably penetrates through the sliding seat 17. A elastic spring 21 is arranged between the connecting plate 22 and the support frame 16. And the elastic spring 21 is fixedly connected to the connecting plate 22 and the support frame 16 and sleeved on the pull rod 18. By pulling the pull rod 18, the pull rod 18 drives the connecting plate 22 to move. Further, the connecting plate 22 drives the resisting block 20 to separate from the sliding rod 11, releasing the fixation of the sliding seat 17, facilitating the movement of the sliding seat 17. And when the movement is completed, the pulling of the pull rod 18 is released. Further, the elastic spring 21 drives the connecting plate 22 to rebound. It should be noted that here the elastic spring 21 is preferably of the cl225 series with a diameter of 5.8mm and an elastic modulus E of 206, having a certain durable elasticity. Thus, the connecting plate 22 drives the resisting block 20 to abut against the sliding rod 11 through the sliding seat 17.

[0023] Inner grooves 15 are formed in the outer walls of the adjusting rods 13. A plurality of rollers 14 are fixedly connected to the outer walls of the inner grooves 15 in a linear array. By providing the plurality of rollers 14, it is convenient for the conveyance of products.

[0024] Limit blocks 23 are fixedly connected to the outer side walls of the adjusting rods 13. Grooves adapted to the limit blocks 23 are formed in the outer side walls of the guide rods 8. Through the limit blocks 23 and the grooves, it is convenient for the adjusting rods 13 and the guide rods 8 to be aligned, improving the accuracy.

[0025] The implementation principle of the conveying device of the product packaging machine in the embodiment of the present application is as follows: First, according to the size of the packaged product, the worker rotates the rotating handle 9, so that the rotating handle 9 drives the bidirectional lead screw 6 to rotate. Since the thread opening directions on both sides of the bidirectional lead screw 6 are opposite, the bidirectional lead screw 6 drives the driving rods 7 on both sides to move towards each other or in the opposite direction. Thus, the driving rods 7 drive the guide rods 8 on both sides to be adjusted. At the same time, by pulling the pull rod 18, the pull rod 18 drives the resisting block 20 to contract through the connecting plate 22. Thus, the resisting block 20 separates from the sliding rod 11. By sliding the sliding seat 17, the sliding seat 17 drives the adjusting rod 13 to move through the connecting frame 12. Thus, the limit blocks 23 on both sides of the adjusting rod 13 are connected to the grooves on the guide rod 8, and further the adjustment of the two adjusting rods 13 is completed. The pulling of the pull rod 18 is released. The elastic spring 21 drives the connecting plate 22 to rebound, making the resisting block 20 abut against the surface of the sliding rod 11. Then, the driving motor 3 is started through an external power supply, so that the driving motor 3 drives the conveyor belt device 2 to operate, and the conveyor belt device 2 conveys the packaged product. The packaged product enters through the side with a larger opening area of the guide rod 8, and the packaged product on the conveyor belt device 2 is conveyed and adjusted by the two guide rods 8 and the two adjusting rods 13.
