Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to a weighing hopper with a limiting structure. Background Technology

[0002] In the food production process, it is necessary to feed food in a quantitative manner, that is, to feed the material into the hopper by a feeder. The hopper is also equipped with a weighing component. When the material in the hopper reaches the predetermined weight, the feeder will stop working and the hopper can rotate, so that the material in the hopper can be discharged according to the tilt angle of the hopper.

[0003] The feeder has multiple levers. When the feeder rotates, it drives the multiple levers to rotate, and the rotation of the levers can convey the material into the hopper.

[0004] Although the aforementioned material feeder can convey materials, when multiple materials are stacked together, the end of the rotating lever may come into contact with the top of the object, thus creating a hard contact with the object and causing damage to the outer surface of the object.

[0005] To address the aforementioned issues, existing technologies have incorporated a flexible lever structure, as shown in the attached instruction manual. Figure 4 As shown, this prevents damage to the outer surface of the material. However, this leads to new problems. Since the lever is made of a spring in actual use, the spring deforms when it comes into contact with the item. After deforming to a certain extent, it will suddenly return to its original position. During the return, the bottom of the spring may rotate to the bottom of the material, thus throwing the material out of the hopper. This makes it impossible for the hopper to weigh the falling material, and the falling material will also cause unnecessary trouble. Utility Model Content

[0006] In view of this, the present invention provides a weighing hopper with a limiting structure. The present invention can limit the running trajectory of the material during material conveying, thereby effectively preventing the material from falling out of the hopper during conveying.

[0007] To solve the above-mentioned technical problems, this utility model provides a weighing hopper with a limiting structure, including a limiting plate suspended above the hopper. When the material is moved and flies up, it can hit the limiting plate and fall into the hopper. The limiting plate can limit the material.

[0008] The limiting plate is tilted, with the horizontal height of the end of the limiting plate near the feeding roller being higher than the horizontal height of the other end of the limiting plate. When the material is thrown, it will hit the bottom of the limiting plate and fall onto the hopper.

[0009] Side plates are also provided on both sides of the limiting plate. The bottom of the side plates is connected to the hopper. The side plates are used to prevent materials from falling from the side of the hopper.

[0010] The side plate and the hopper are detachably connected, making it easy to remove the side plate and the limiting plate for maintenance of the hopper.

[0011] The side plates are fixed to the hopper with bolts, and the bolt connection allows for quick assembly and disassembly of the side plates.

[0012] The end of the limiting plate away from the feeding roller is also equipped with a baffle by a hinge. The baffle can rotate at the end of the limiting plate and hangs naturally at the hinge shaft. The baffle can limit the material sliding on the hopper.

[0013] The bottom of the baffle is equipped with a counterweight, which can prevent the baffle from rotating when it is hit by materials, thus preventing it from losing its limiting effect.

[0014] The upper surface of the hopper is made into a rough surface, which can reduce the distance that the material slides on the hopper.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0016] 1. Effectively prevents material from flying out: By suspending a limiting plate above the hopper, when material is propelled by the feeder and flies up, it can quickly contact the limiting plate and fall back into the hopper. This design effectively prevents material from accidentally flying out of the hopper due to the action of the feeder, ensuring that all material can be accurately weighed.

[0017] 2. Optimize material conveying path: The limiting plate is set at an angle, with the horizontal height of the end near the feeding roller being higher than that of the other end. This design allows the material to more smoothly hit the bottom of the limiting plate and fall onto the hopper when it is thrown, avoiding disorderly scattering of the material during the conveying process and improving the efficiency and accuracy of material conveying.

[0018] 3. Enhanced side protection: Side plates are added to both sides of the limiting plate and connected to the bottom of the hopper, effectively preventing materials from falling from the sides of the hopper. This design not only improves the overall sealing of the weighing hopper but also further ensures the stability of the materials during the conveying process.

[0019] 4. Easy maintenance and disassembly: The side plates and hopper are detachably connected, especially by bolt fixing, allowing the side plates and limit plates to be easily removed for cleaning, maintenance, and replacement of the hopper. This design improves the maintainability and flexibility of the equipment.

[0020] 5. Added baffle limiting: A baffle is hinged to the end of the limiting plate away from the feeding roller, and equipped with a counterweight, effectively preventing the material from sliding beyond the limiting range on the hopper. The presence of the baffle not only further enhances the material limiting effect, but also improves the overall safety and stability of the weighing hopper.

[0021] 6. Increase the surface friction of the hopper: By making the upper surface of the hopper rough, the distance that the material slides on the hopper is effectively reduced. When combined with the counterweight set at the bottom of the baffle, the material can be further prevented from hitting the baffle and causing it to rotate, thus ensuring the limiting effect of the baffle.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0029] A weighing hopper 1 with a limiting structure, such as Figure 1 , 2 As shown, the material includes a limiting plate 2 suspended above the hopper 1. The limiting plate 2 is placed at an angle, that is, the horizontal height of the end of the material limiting plate 2 near the feeding roller is higher than the horizontal height of the other end of the limiting plate 2. That is, if the bottom of the spring lifts the material when the spring is resetting, the material will come into contact with the downward side of the limiting plate 2, and then the material will fall down under its own weight and fall normally onto the hopper 1, so that the material can be weighed normally.

[0030] Specifically, such as Figure 1 , 2 As shown, side plates 3 are also fixedly connected to both sides of the limiting plate 2. The top of the side plate 3 is connected to the limiting plate 2, and the bottom of the side plate 3 is connected to both sides of the hopper 1. The hopper 1 can provide support for the limiting plate 2 through the two side plates 3.

[0031] It is worth mentioning that if the spring touches the corner of the material, the spring may push the material to move to both sides of the hopper 1, so that the two side plates 3 can be positioned on both sides of the hopper 1 to limit the material. In this way, the material can fall back into the hopper 1 when it touches the inner side wall of the limiting plate 2.

[0032] The side plate 3 and the hopper 1 are detachably connected; specifically in this embodiment, as shown below... Figure 1 As shown, the side plate 3 is fixed to the hopper 1 by bolts, which means that the side plate 3 can be quickly installed and quickly removed by bolts, thus facilitating the maintenance of the hopper 1.

[0033] Meanwhile, the side plate 3 and the hopper 1 can also be connected by a snap-fit ​​mechanism, which allows the side plate 3 and the hopper 1 to be disassembled and installed.

[0034] like Figure 1 , 2 As shown in Figure 3, the end of the limiting plate 2 away from the feeding roller is also provided with a baffle 4 by a hinge. The baffle 4 hangs naturally at the hinge shaft. That is, when the spring moves the material, the material may slide quickly along the upper surface of the hopper 1 and fall off the hopper 1. The baffle 4, which is hinged at the end of the limiting plate 2, can make the material slide quickly on the hopper 1 and then come into contact with the baffle 4, thus blocking it on the upper surface of the hopper 1. In this way, the hopper 1 can weigh the material normally.

[0035] Once the weight in hopper 1 reaches the target, hopper 1 will rotate. After hopper 1 rotates, a gap will be left between baffle 4 and the upper surface of hopper 1, so that the material in hopper 1 can be discharged through the gap between baffle 4 and hopper 1 as hopper 1 tilts.

[0036] Furthermore, a counterweight 5 is provided at the bottom of the baffle 4. The counterweight 5 is used to increase the overall weight of the baffle 4. The counterweight 5 can be an iron block or other object fixed to the bottom of the baffle 4. That is, by increasing the weight of the baffle 4 through the counterweight 5, the baffle will not rotate due to the impact after the material slides or flies up and hits the baffle. In this way, the material will not fall from the hopper when it is not rotating.

[0037] At the same time, the counterweight also ensures that the baffle will not get stuck between the limit plate and the hopper and cannot rotate with gravity when the hopper is rotating.

[0038] The upper surface of the hopper 1 is also designed as a rough surface. This rough surface can be formed by laying a rubber layer or by providing several grooves or protrusions on the upper surface of the hopper. In other words, the design of the rough surface can increase the friction between the upper surface of the hopper 1 and the object, thereby reducing the impact force when the material moves. In conjunction with the counterweight 5, it can better ensure the limiting effect of the hopper 1 on the material transportation.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 according to the specific circumstances.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
