The limiting rod passes through the limiting hole and inserts into the limiting groove to fix the position of the hopper.

[0004] However, the device still has the following problems: during the feed filling and conveying process, the bag opening is not sealed, the center of gravity is high, and the friction at the bottom of the bag is small, so it is easy to tip over and cause feed to spill during the conveying process. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, a feed filling anti-tipping device is provided to solve the problems mentioned in the above technical background.

[0006] The technical solution adopted by this utility model to solve its technical problem is: This utility model proposes a feed filling anti-tipping device, including a frame, with guide plates symmetrically arranged on both sides of the frame, and a plurality of guide rollers arranged on the guide plates along the conveying direction of the frame. The guide rollers are rotatably connected to the guide plates through a rotating shaft. The guide plates are also provided with a sliding groove intersecting the length direction of the frame, and the guide rollers can slide in the sliding groove while rotating. The guide rollers and the guide plates are connected by a compression spring.

[0007] Preferably, a number of connecting plates are fixedly connected to the guide plate, each group including two connecting plates, which respectively cooperate with the upper and lower ends of the guide roller, and the groove is formed on the connecting plate.

[0008] Preferably, a push plate is slidably connected to the connecting plate, one side of which abuts against the rotating shaft of the guide roller, and the other side is fixed to one end of the compression spring.

[0009] Preferably, an adjusting seat is fixed on the connecting plate, and an adjusting rod is threadedly connected to the adjusting seat. The end of the adjusting rod abuts against the other end of the compression spring.

[0010] Preferably, the connecting plate has a guide groove for the rotating shaft to slide into the slide groove. The guide groove has a horizontal groove and an inclined groove, and the opening direction of the inclined groove is opposite to the conveying direction.

[0011] Preferably, the guide plate has an input end and an output end, the input ends of the two guide plates are folded outward to form a flared mouth, and the distance between the input ends of the two guide plates is greater than the distance between the output ends.

[0012] Preferably, the guide plate has an opening, and the side of the guide roller can extend out of the opening to contact the feed bag.

[0013] Preferably, both ends of the frame are slidably connected to slide rods, the guide plate is fixed to the slide rods, and positive and negative threaded rods are rotatably connected to the frame. The slide rods at both ends are respectively connected to the positive and negative threads on the positive and negative threaded rods.

[0014] Preferably, one end of the positive and negative lead screw is slidably connected to a handle, the handle is connected to the positive and negative lead screw via a tension spring, at least one insertion rod is fixed on the handle, and the slide rod is provided with a plurality of insertion holes for the insertion rod to slide freely into.

[0015] Preferably, a lifting seat is fixed on the slide rod, a lifting rod is slidably connected inside the lifting seat, the lifting rod is fixed to the guide plate, and a locking bolt is threadedly connected to the lifting seat to lock the lifting of the lifting rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a guide plate, on which a guide roller is rotatably connected. During the forward conveying of feed, the guide roller can provide support for the feed. The guide roller can make the friction between the feed bag and the guide plate less than the friction between the feed bag and the bottom conveyor belt, which helps the feed bag to remain upright during the conveying process, reduces the occurrence of spillage, and eliminates the need for manual bag holding, thus improving production efficiency.

[0017] 2. The guide roller and guide plate of this utility model are connected by a compression spring. The spring force can adaptively increase or decrease with the offset of the bag. Even if the bag is slightly tilted, it can be flexibly corrected by the spring force to keep the feed bag upright. At the same time, the spring force is adjustable to adapt to feeds of different densities. The spring force prevents the guide roller from rigidly squeezing the feed bag, effectively reducing the occurrence of bag breakage.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1 refer to Figures 1-5This embodiment proposes a feed filling anti-tipping device, including a frame 1, with a support foot fixed at the bottom of the frame 1. The frame 1 has several rotating conveyor rollers, and a conveyor belt is sleeved on the conveyor rollers. The conveyor belt is arranged along the length direction of the frame 1. One end of one of the conveyor rollers of the conveyor belt is directly connected to a motor to drive the conveyor belt to rotate. After the feed bag is filled, it is placed on the conveyor belt for transport to the next process.

[0023] Specifically, one end of the frame 1 is equipped with a feed bin 20, and the other end is equipped with a re-inspection scale or a sewing machine. After the feed bag is filled with feed from the feed bin 20, it is placed on the frame 1 so that the feed bag is conveyed towards the re-inspection scale or the sewing machine.

[0024] Guide plates 2 are symmetrically arranged on both sides of the frame 1. Several guide rollers 3 are arranged on the guide plates 2 along the conveying direction of the frame 1. The guide rollers 3 are rotatably connected to the guide plates 2 through a rotating shaft. The guide plates 2 are also provided with a sliding groove 4 that intersects with the length direction of the frame 1. The guide rollers 3 can slide in the sliding groove 4 while rotating. The guide rollers 3 and the guide plates 2 are connected by a compression spring 5.

[0025] Specifically, when the feed bag is placed on the frame 1 and conveyed by the conveyor belt, the feed bag and the guide roller 3 rotate relative to each other as the conveyor belt runs, so that the friction between the guide roller 3 and the feed bag is less than the friction between the feed bag and the bottom conveyor belt. The guide plate 2 provides vertical support for the feed bag during the conveying process.

[0026] The guide plate 2 has an opening, and the side of the guide roller 3 can extend out of the opening to contact the feed bag.

[0027] Specifically, the guide plate 2 has several openings, allowing the side of the guide roller 3 to extend out of the surface of the guide plate 2. The openings are not connected to each other. Compared to the openings being connected to form a long strip, this method can effectively strengthen the guide plate 2 and provide better support for the feed bag.

[0028] The guide plate 2 has an input end and an output end. The input ends of the two guide plates 2 are folded outward to form a flared mouth, and the distance between the input ends of the two guide plates 2 is greater than the distance between the output ends.

[0029] Specifically, after the feed bags are filled, the flared opening can provide guidance for supporting the feed bags in advance.

[0030] Specifically, the distance between the input ends of the two guide plates 2 is greater than the distance between the output ends, which can guide the feed bag to move along the conveying center line, avoid the bag from falling or getting stuck due to offset, and ensure the stability of the conveying path; at the same time, through the gradually narrowing structure, the tilt and skew of the bag are corrected, keeping the bag upright and centered, which is convenient for subsequent stacking, sealing, barcode scanning or mechanical gripping.

[0031] Several sets of connecting plates 6 are fixedly connected to the guide plate 2. Each set includes two connecting plates 6, which are respectively matched with the upper and lower ends of the guide roller 3. The slide groove 4 is opened on the connecting plate 6.

[0032] Specifically, the spring force is perpendicular to the conveying direction, and the guide roller 3 has a range of motion, so it will not cause rigid compression to the bag body, preventing the feed bag from breaking and leaking; at the same time, the spring force of the spring 5 can adaptively increase or decrease with the offset of the bag body, so even if the bag body is slightly tilted, it can be flexibly corrected by the spring force to keep the feed bag upright.

[0033] A push plate 7 is slidably connected to the connecting plate 6. One side of the push plate 7 abuts against the rotating shaft of the guide roller 3, and the other side is fixed to one end of the compression spring 5.

[0034] Furthermore, a bearing 19 is fixedly sleeved on the rotating shaft of the guide roller 3, and the push plate 7 abuts against the outer ring of the bearing 19.

[0035] An adjusting seat is fixed on the connecting plate 6, and an adjusting rod 8 is threadedly connected to the adjusting seat. The end of the adjusting rod 8 abuts against the other end of the compression spring 5.

[0036] Specifically, a turntable is rotatably connected to the end of the adjusting rod 8, and the compression spring 5 is fixedly connected to the turntable.

[0037] Specifically, the spring force of spring 5 is adjustable, which can be used for feeds of different densities. The elasticity prevents the guide roller from causing rigid compression on the feed bag, effectively reducing the occurrence of bag breakage.

[0038] Specifically, for the same bag size, when filled with denser feed, rotating the adjusting rod 8 compresses the spring 5, increasing its elasticity. Because the feed density is high, its bulk is low, requiring a larger spring force to assist the feed movement within the bag and fill the holes. Conversely, when filled with less dense feed, rotating the adjusting rod 8 extends the spring 5, decreasing its elasticity. Because the feed bulk is high, only a smaller elastic force is needed to assist the feed in filling the bag's voids under gravity. Therefore, the elasticity can be adjusted according to the weight, thickness, and bulk of the feed bag, making it suitable for different types of bags and feeds of varying densities.

[0039] The connecting plate 6 has a guide groove 9 for the rotating shaft to slide into the slide groove 4. The guide groove 9 has a horizontal groove and an inclined groove, and the opening direction of the inclined groove is opposite to the conveying direction.

[0040] Specifically, the horizontal trough is parallel to the conveying direction, and the inclined trough has a certain angle with the horizontal trough. Therefore, the guide roller 3 is not in contact with the guide plate 2 before it is placed in place. The side of the guide roller 3 is exposed from the surface of the guide plate 2 only after the guide roller 3 slides to the end of the inclined trough. This can reduce the width of the opening on the guide plate 2 and further improve the strength of the guide plate 2.

[0041] Example 2 refer to Figures 1-5 As shown, the other structures are the same as in Embodiment 1. The difference is that this embodiment takes into account the problem that feed bags have different diameters and heights.

[0042] Both ends of the frame 1 are slidably connected to slide rods 10, the guide plate 2 is fixed to the slide rods 10, and the frame 1 is also rotatably connected to positive and negative threaded rods 11, with the slide rods 10 at both ends respectively connected to the positive and negative threaded rods 11.

[0043] Specifically, the slide rods 10 at both ends of the frame 1 are respectively connected to the positive and negative threads of the positive and negative screws. Therefore, when the positive and negative screws 11 are rotated, the two guide plates 2 can move towards each other or away from each other to accommodate feed bags of different diameters.

[0044] A handle 12 is slidably connected to one end of the positive and negative lead screw 11. The handle 12 is connected to the positive and negative lead screw 11 through a tension spring 13. At least one insertion rod 14 is fixed on the handle 12. Several insertion holes 15 are opened on the slide rod 10 for the insertion rod 14 to slide freely into.

[0045] Specifically, after rotating the positive and negative lead screws 11, the insertion rod 14 is slid into the insertion hole to avoid the influence of vibration, reduce the loosening of the positive and negative lead screws 11 during the conveying process, and prevent changes in the distance between the guide plates 2.

[0046] A lifting seat 16 is fixed on the slide rod 10. A lifting rod 17 is slidably connected inside the lifting seat 16. The lifting rod 17 is fixed to the guide plate 2. A locking bolt 18 is threadedly connected to the lifting seat 16 to lock the lifting of the lifting rod 17.

[0047] Specifically, by loosening and tightening the locking bolts 18, the lifting rod 17 and the lifting seat 16 can slide relative to each other or be locked relative to each other, thereby driving the guide plate 2 to be adjusted in the height direction to adapt to feed bags of different heights.

[0048] Adjust the positive and negative screws 11 according to the diameter of the feed bag so that they drive the two guide plates 2 to move to the appropriate distance. Adjust the length of the lifting rod 17 extending from the lifting seat 16 according to the filling height of the feed bag so that the lifting rod 17 drives the guide plate 2 to move to the appropriate height. After adjustment, rotate the adjusting rod 8 according to the density or fluffiness of the filled feed so that it drives the spring 5 to compress or extend, thereby adapting to the density or fluffiness of the filled feed.

[0049] The feed is first filled at the lower end of the feed hopper 20. After filling, it is placed on the frame 1 and conveyed backward. The flared mouth of the guide plate 2 guides the feed bag, and the guide roller 3 reduces the friction between the feed bag and the guide plate 2. When there are voids in the feed bag caused by filling, the spring 5 can also drive the guide roller 3 to roll the bag body. The continuous elasticity of the spring 5 keeps the guide roller close to the bag body. Even if the bag is slightly tilted, it can be kept upright and centered through flexible correction, which indirectly helps the feed in the bag to fill naturally under the action of gravity and reduces voids.

[0050] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
