[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0040] Please see Figure 1 , Figure 2 and Figure 3 To achieve the above objectives, this utility model provides a belt-driven circular wrapping machine. The specific technical solution is as follows: A belt-driven circular wrapping machine includes a power mechanism 100, which includes a support frame 110 welded from square steel. The support frame 110 is used for the installation and fixation of the entire device. A traveling wheel 112 (i.e., tire) is installed at the bottom of the support frame 110. The traveling wheel 112 facilitates the movement of the entire device, thereby changing its position, greatly improving the mobility and flexibility of the entire device. A motor 120 is installed on the lower side of the support frame 110. Specifically, the output shaft of the motor 120 is fixed with a pulley, which is connected to the flywheel 130 via a belt. Thus, the motor 120 can drive the flywheel 130 to rotate via the belt. The center of the flywheel 130 is fixed with a power shaft 140 via a key, so that the flywheel 130 can drive the power shaft 140 to rotate. The power shaft 140 is connected to the bundling mechanism 200, so that the power shaft 140 can provide working power to the bundling mechanism 200. The bundling mechanism 200 is used to bundle raw materials.

[0041] Please see Figure 4 , Figure 6 and Figure 7 Specifically, the bundling mechanism 200 includes a rear fixing mechanism 210 and a front movable mechanism 220. The rear fixing mechanism 210 includes two symmetrical rear wall plates 211, and a plurality of first rollers 212 are rotatably mounted between the two rear wall plates 211. The first rollers 212 are arranged according to... Figure 7The layout is as shown. The power shaft 140 is connected to one of the first rollers 212 via a belt or chain. Adjacent first rollers 212 are connected together via a chain. A rear belt 213 is connected between several first rollers 212. The rotation of the first rollers 212 can drive the rear belt 213 to rotate cyclically, thereby enabling the power shaft 140 to provide power to the rear fixing mechanism 210. A protective cover 111 is provided on the outside of the bundling mechanism 200. The protective cover 111 is fixed on the support frame 110. The protective cover 111 isolates the moving parts such as chains and sprockets on the rear fixing mechanism 210 and the front moving mechanism 220, preventing them from touching the human body or external objects, thus playing a role in isolation and protection.

[0042] Please see Figure 4 , Figure 6 and Figure 7 The upper ends of the two rear wall plates 211 are fixed with connecting shafts 214. The front movable mechanism 220 includes two symmetrically arranged front wall plates 221. The two front wall plates 221 are rotatably connected to the connecting shafts 214, so the front movable mechanism 220 can rotate around the connecting shafts 214. Therefore, the included angle between the front movable mechanism 220 and the rear fixed mechanism 210 can be changed. Several second rollers 222 are provided on the front wall plates 221. The several second rollers 222 are connected by a front belt 223. The front belt 223 can drive the several second rollers 222 to rotate. The raw materials to be packaged enter the gap between the rear fixed mechanism 210 and the front movable mechanism 220. Under the action of the rear belt 213 and the front belt 223, the raw materials are kneaded and processed into round bales, realizing the bale processing of the raw materials.

[0043] Please see Figure 1 and Figure 2 In addition, an inner film feeding mechanism 300 is provided on the upper side of the baling mechanism 200. The inner film feeding mechanism 300 is used to provide the baling mechanism 200 with packaging film for baling. Specifically, the inner film feeding mechanism 300 includes a first mounting frame 310, on which a first film feeding roller 320 is rotatably mounted. A film shaft for winding raw materials is mounted on the first film feeding roller 320. A first cutting part 330 is provided on one side of the first film feeding roller 320. The first cutting part 330 is mounted on the first mounting frame 310 and is used to cut the film. After the raw material enters the baling mechanism 200, the raw material is kneaded and processed into round bales. Then, the film on the first film feeding roller 320 comes into contact with the round bales. As the round bales rotate, the outer side of the round bales is wrapped with film to form an inner film. Then, the first cutting part 330 cuts the film, and the round bales continue to the next step of processing.

[0044] Please see Figure 3 , Figure 4 and Figure 5It should be noted that a material conveying mechanism 400 is provided at the entrance of the bundling mechanism 200. The material conveying mechanism 400 includes a first baffle 410. First rotating shafts 420 are rotatably mounted on both sides of the first baffle 410. A first conveying belt 430 is connected between the two first rotating shafts 420. A first sprocket 440 is fixed to one end of one of the first rotating shafts 420. A second sprocket 450 is connected to one side of the first sprocket 440 via a chain drive. A second rotating shaft 460 is fixed to the second sprocket 450. The second rotating shaft 460 is connected to the bundling mechanism 200 via a drive.

[0045] By setting a feeding mechanism 400 at the entrance of the bundling mechanism 200, when raw materials need to be bundled, the raw materials are placed onto the first feeding belt 430 of the feeding mechanism 400 using a tool. The first feeding belt 430 runs upward under the drive of the first rotating shaft 420, and then the first feeding belt 430 transports the raw materials on it to the entrance of the bundling mechanism 200, and then enters the interior of the bundling mechanism 200 for bundling. The feeding mechanism 400 greatly improves work efficiency and facilitates work. The staff does not need to manually feed the raw materials into the opening of the bundling mechanism 200, and the safety is greatly improved.

[0046] Please see Figure 4 and Figure 5 Preferably, a clutch 470 is provided at the end of the second rotating shaft 460. The power of the conveying mechanism 400 can be cut off or connected by operating the clutch 470, so as to facilitate the start and stop of the conveying mechanism 400. In addition, directional wheels 480 are installed on both sides of the lower end of the first baffle 410 to facilitate the movement of the conveying mechanism 400.

[0047] Please see Figure 1 , Figure 3 and Figure 8 In addition, a material leakage recovery mechanism 500 is provided on the lower side of the bundling mechanism 200. The material leakage recovery mechanism 500 includes a second baffle 510. A third rotating shaft 520 is provided on both sides of the second baffle 510. A second conveyor belt 530 is connected between the two third rotating shafts 520. A third sprocket 540 is fixed at the end of one of the third rotating shafts 520. The third sprocket 540 is connected to the bundling mechanism 200.

[0048] By setting a material leakage recovery mechanism 500 at the lower end of the bundling mechanism 200, excess material will fall from the bundling mechanism 200 during the bundling process and then fall onto the second conveyor belt 530 below. It will be transported backward with the second conveyor belt 530 and then fall off the second conveyor belt 530, thus realizing the recovery of leakage material. There is no need for manual collection of leakage material, which greatly improves work efficiency.

[0049] Please see Figure 3 , Figure 9and Figure 10 A unloading mechanism 600 is provided on one side of the baling mechanism 200. The unloading mechanism 600 includes a second mounting frame 610. A drive unit 620 is installed on the lower side of the second mounting frame 610. The drive unit 620 is preferably a motor. The drive unit 620 is connected to multiple sets of third rollers 630 through gears, pulleys and other means. The multiple sets of third rollers 630 are connected to an unloading belt 640. The baled raw materials can slide onto the unloading belt 640. The unloading belt 640 on the third rollers 630 is driven to move, thereby transporting the baled straw bales away from the second mounting frame 610 and realizing unloading.

[0050] Please see Figure 3 , Figure 9 and Figure 10 An outer film feeding mechanism 700 is provided on one side of the unloading mechanism 600. The outer film feeding mechanism 700 includes a third mounting frame 710, on which a second film feeding roller 720 is mounted. A second cutting part 730 is provided on one side of the second film feeding roller 720. The second cutting part 730 is used to cut the film. Before unloading the bales after being bundled by the bundling mechanism 200, an outer film needs to be wrapped around the outside. The outer film feeding mechanism 700 wraps the outer film around the bales, and then the second cutting part 730 cuts the outer film.

[0051] Working principle:

[0052] The feeding mechanism 400 is manually or mechanically fed with hay, which is then conveyed into the baling mechanism 200. The baling mechanism 200, through its rear fixing mechanism 210 and front moving mechanism 220, drives its rear belt 213 and front belt 223 to knead the hay into a cylinder. Once the cylinder reaches a certain shape, the inner film feeding mechanism 300 provides inner film, wrapping the entire cylinder with several layers of inner film. The purpose of wrapping with inner film is to prevent the hay bales from crumbling during the next process.

[0053] After the inner membrane is cut, the cylinder mounted on the support frame 110 drives the front movable mechanism 220 to rotate around the connecting shaft 214, thereby realizing the opening action of the front movable mechanism 220. Driven by the rotation of the rear belt 213 on the rear fixed mechanism 210, the entire bale is driven to roll onto the unloading mechanism 600 of the round bale rotation.

[0054] With the cooperation of the unloading mechanism 600 and the outer film feeding mechanism 700, the entire bale is driven to be wrapped with several layers of outer film. After the bale is wrapped with the outer film, the cylinder designed on the unloading mechanism 600 and the support frame 110 drives the rotating shaft of the unloading mechanism 600 to tilt, so that the bale leaves the device and slides to the ground, and the whole work is completed.

[0055] It should be noted that the motion state and trajectory of each mechanism in this device can be automatically controlled by CNC program or PLC programming, and automatic start-stop and automatic operation can be achieved in conjunction with position switches. The above-mentioned programs and programming are common knowledge to those skilled in the art, so they will not be described in detail here.

[0056] The specific model and specifications of motor 120 need to be determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0057] The power supply and principle of motor 120 are clear to those skilled in the art and will not be described in detail here.

[0058] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0059] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
