[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: A weighing and packaging machine with a spiral feeding structure includes a feeding pipe 1, a feeding port 2 at the top of the lower end of the feeding pipe 1, and a discharging port 3 at the bottom of the upper end of the feeding pipe 1; an adjustment structure for adjusting the angle of the feeding pipe 1 is installed at the bottom of the feeding pipe 1, and the adjustment structure includes a steering frame 6 and an adjustment frame 7 installed at the bottom of the feeding pipe 1, with sliding rods 8 fixedly connected to both sides of the steering frame 6, and mounting sleeves 9 aligned with the sliding rods 8 on both sides of the adjustment frame 7, and the sliding rods 8 are slidably connected inside the mounting sleeves 9; a lead screw 10 is rotatably connected to the middle of the steering frame 6, and the lead screw 10 is away from the steering frame 6. One end of the frame 6 is threaded to the middle of the adjusting frame 7; a weighing structure for weighing and separating materials is installed at the lower end of the discharge port 3; a screw rod 4 is rotatably connected inside the conveying pipe 1, and the screw rod 4 is driven by a motor installed at the lower end of the conveying pipe 1, and adjusting grooves 5 are provided on both sides of the conveying pipe 1; one end of the conveying pipe 1 near the inlet 2 is rotatably connected to the inside of the bogie 6, and the adjusting grooves 5 on both sides of the conveying pipe 1 are slidably connected to the inner side of the upper end of the adjusting frame 7; a steering wheel 12 is installed on both sides of the bogie 6, and a support wheel 11 is installed on both sides of the adjusting frame 7, and the steering wheel 12 is rotatably connected to both sides of the bogie 6.

[0027] During the use of the device, the material is first added into the conveying pipe 1 through the feed inlet 2. The screw rod 4 is driven by the motor to rotate in the conveying pipe 1. The rotation of the screw rod 4 transports the material inside the conveying pipe 1 to the discharge outlet 3. The material is then discharged into the weighing structure through the conveying pipe 13 through the discharge outlet 3, so that the material is evenly distributed.

[0028] The material conveying pipe 1 is supported by the bogie 6 and the adjusting frame 7. During use, the height of the discharge port 3 at the upper end of the material conveying pipe 1 needs to be adjusted according to the different heights of the device. At this time, the screw 10 is rotated to make it rotate inside the bogie 6. The screw 10 will rotate inside the bogie 6. The rotation of the mounting sleeve 9 inside the bogie 6 drives the adjusting frame 7 to move away from or closer to the bogie 6.

[0029] When the adjusting frame 7 approaches the bogie 6, the top of the adjusting frame 7 will slide downward inside the adjusting groove 5, thereby driving the conveying pipe 1 to rotate around the top of the bogie 6. At this time, the height of the upper end of the conveying pipe 1 will be raised, thereby raising the height of the discharge port 3. Conversely, when the adjusting frame 7 moves away from the bogie 6, the height of the discharge port 3 will be lowered, thus facilitating the flexible arrangement of the weighing structure.

[0030] During the movement of the adjusting frame 7, the slide bar 8 will slide inside the mounting sleeves 9 on both sides of the adjusting frame 7, thereby fixing its movement state and connecting the bogie 6 and the adjusting frame 7 into a whole, improving the stability of the device. At the same time, the device can be steered by the steering wheel 12 during the movement of the device.

[0031] Example 2: Based on Example 1, a weighing structure is also disclosed, the specific structure of which is as follows: The weighing structure includes a conveying pipe 13 installed at the bottom of the discharge port 3, and a housing 14 is fixedly connected to the bottom end of the conveying pipe 13 away from the discharge port 3; a rotating block 15 is rotatably connected inside the housing 14, and the rotating block 15 is driven by a servo motor installed on one side of the housing 14; a weighing groove 16 is installed on the outside of the rotating block 15, and the weighing groove 16 and the top of the housing 14 are aligned with each other, and an electrically controlled door is installed on the top of the housing 14; a discharge groove 17 is provided on one side of the bottom of the housing 14, and the discharge groove 17 is distributed along the tangent of the outside of the housing 14, and a fixing frame 18 is fixedly connected to the outside of the housing 14.

[0032] After passing through the material conveying pipe 1, the material will enter the housing 14 through the material conveying pipe 13. The material inside the housing 14 will fall into the weighing trough 16 outside the rotating block 15 and be weighed through the weighing trough 16. When the material reaches the predetermined weight, the electric control door at the top of the housing 14 will close. At this time, the servo motor will drive the rotating block 15 to rotate, thereby driving the weighing trough 16 to rotate around the rotating block 15, pouring the weighed material into the housing 14. The material inside the housing 14 will be discharged out of the device through the discharge trough 17.

[0033] The weighing structure is supported by the fixed frame 18, and the conveying pipe 13 can be extended or adjusted at will, which facilitates the arrangement and installation of the weighing structure and prevents the transportation system of the weighing structure from occupying too much space, making it inconvenient to arrange and install the weighing structure.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
