Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a lower frame for a loading and unloading machine. Background Technology

[0002] In modern industrial production, loading and unloading machines are key equipment on automated production lines, playing a bridging role in transporting materials from one machine to another. In this process, the lower frame, as the core support structure of the loading and unloading machine, directly affects the working efficiency and operational reliability of the entire machine due to its design rationality, stability, and durability.

[0003] Referring to the existing patent publication number: CN107389114A, a lower frame for a loading and unloading machine is disclosed. The lower frame is cuboid, including six sides: front, back, left, right, top, and bottom, as well as a rectangular frame. Each side is correspondingly arranged on the corresponding surface of the rectangular frame. Using a lower frame for a loading and unloading machine results in fast material conveying speed, high efficiency, good matching accuracy, and high degree of automation. The edges of the rectangular frame are fixedly connected together by welding square tubing, which provides good stability, good safety, and long service life.

[0004] However, in actual use, the existing lower frame has a problem: the accuracy of the material is particularly critical when loading and unloading. If the material is misplaced or irregular, it can easily affect the machine's gripping and reading. The existing frame is cumbersome to straighten the misplaced material and increases energy consumption during the operation, making it difficult to make full use of the kinetic energy generated during material transportation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lower frame for a loading and unloading machine. This invention incorporates an anti-deviation component above the frame, which generates kinetic energy during material transport by the conveying mechanism. The material then contacts the connecting piece and the lever. As the material continues to feed, the connecting piece pulls the limiting plate closer to the center to correct the material's orientation. Simultaneously, the lever, under the action of the rotating rod, swings upward and pulls the connecting piece away from the material, preventing obstruction and allowing the material to self-align during transport, thus improving utilization.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lower frame for a loading and unloading machine, comprising:

[0008] The rack, as the main structure of the entire lower rack, provides installation support;

[0009] A bracket is installed on the upper part of the frame. A lever is connected to the upper inner side of the bracket via a rotating rod. An anti-deviation component that can be moved in the horizontal direction is installed on the surface of the bracket.

[0010] A conveying mechanism is installed on the inner side of the frame, and a protective component is connected to the inner side of the frame, with the protective component located at the end of the conveying mechanism.

[0011] The present invention is further configured such that the anti-deviation component includes: a connecting rod, an elastic element two, a limiting plate, and a connecting member;

[0012] The connecting rod is connected through the surface of the bracket, the limiting plate is installed at one end of the connecting rod, the two elastic elements are connected between the limiting plate and the bracket, and the connecting member is connected between the limiting plates.

[0013] The present invention is further configured such that the second elastic element is located outside the connecting rod, and the limiting plate is located above the conveying mechanism.

[0014] The present invention is further configured such that the connector is a pull rope, and the connector is connected to the lever.

[0015] The present invention further comprises the following components for the conveying mechanism: a motor, a conveyor belt, a drive shaft, and a transmission wheel;

[0016] All motors are mounted on the surface of the frame, all drive shafts are connected to the output end of the motors, all transmission wheels are mounted on the surface of the drive shafts, the conveyor belt is connected between the transmission wheels, and a support part located inside the conveyor belt is installed on the inner side of the frame.

[0017] The present invention further provides that the protective component includes: a buffer plate, a rotating rod, and an elastic element;

[0018] The buffer plate is installed on the inner side of the frame via a rotating rod, and the elastic element is connected between the buffer plate and the frame.

[0019] The present invention is further configured such that the buffer plate is inclined downward in the horizontal direction, and one end of the buffer plate is in contact with the conveyor belt.

[0020] The beneficial effects of this utility model are as follows: By constructing an anti-deviation component above the frame, this utility model can generate a certain amount of kinetic energy when the material is conveyed by the conveying mechanism. At this time, the material will come into contact with the connector and the lever. As the material continues to be fed, the connector will pull the limiting plate closer to the center to perform a certain degree of alignment on the material passing through. Then, the lever will swing upward under the action of the rotating rod and pull the connector away from the material, avoiding obstruction of the material. This allows the material to be aligned by itself during transmission, improving utilization.

[0021] 1. The lower frame of the loading and unloading machine is equipped with an anti-deviation component that works in conjunction with the conveying mechanism. This allows the conveying mechanism to generate a certain amount of kinetic energy when transporting materials. At this time, the materials will come into contact with the connecting piece and the lever. As the materials continue to feed, the connecting piece will pull the limiting plate closer to the center to correct the materials in the path. Then, the lever will swing upward under the action of the rotating rod and pull the connecting piece away from the materials, avoiding obstruction of the materials. This allows the materials to be corrected on their own during transport, making operation convenient, improving utilization, and reducing energy consumption.

[0022] 2. The lower frame of the loading and unloading machine is equipped with protective components. After the material is transported, a buffer plate is connected to the end of the conveyor belt. The material can be supported by the buffer plate during the downward feeding process. Under the action of gravity, the buffer plate can be rotated by a rotating rod and compressed by an elastic element, thereby reducing the impact of the material and reducing damage. The buffer plate can also be reset after the material is removed, which is more flexible and improves protection. Attached Figure Description

[0028] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0029] The embodiments of this patent 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 patent, and should not be construed as limiting this patent.

They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0031] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0032] Reference Figures 1 to 4 A lower frame for a loading and unloading machine includes: a frame 1, which serves as the main structure of the entire lower frame, providing installation support and ensuring the stability and reliability of the entire device; a bracket 5, which is installed on the upper part of the frame 1 and serves to connect and support other functional components; a lever 7 is connected to the upper inner side of the bracket 5 via a rotating rod 15; an anti-deviation component is installed on the surface of the bracket 5 and is movable in the horizontal direction, enabling flexible rotation of the lever 7 and guiding the movement of the deviation component to prevent material from shifting or misaligning during conveying; a conveying mechanism is installed on the inner side of the frame 1, responsible for conveying materials from one place to another, realizing continuous and efficient material handling; a protective component is connected to the inner side of the frame 1 and is located at the end of the conveying mechanism; during material handling, the protective component can prevent personnel injury or equipment damage caused by accidental material falling or impact, improving the protective effect.

[0033] Specifically, refer to Figures 1 to 3 The anti-deviation assembly includes: a connecting rod 6, an elastic element 16, a limiting plate 8, and a connecting member 9; the connecting rod 6 is connected through the surface of the bracket 5, the limiting plate 8 is installed at one end of the connecting rod 6, the elastic elements 16 are connected between the limiting plate 8 and the bracket 5, and the connecting member 9 is connected between the limiting plates 8. In this embodiment, the limiting plate 8 is connected to the bracket 5 through the connecting rod 6 and the elastic element 16, and the two limiting plates 8 can move together when connected by the connecting member 9, so that the elastic element 16 can be stretched during the movement, thereby facilitating the subsequent reset of the anti-deviation assembly.

[0034] Furthermore, the elastic element 2 16 is located on the outside of the connecting rod 6, which can improve the stability of the movement of the connecting rod 6 and the limiting plate 8 and reduce swaying. The limiting plate 8 is located above the conveying mechanism. Through this design, the material can be constrained to prevent it from shifting or misaligning during the conveying process, ensuring that the material can be conveyed along the predetermined track, thereby improving the accuracy and stability of material handling.

[0035] Furthermore, the connector 9 is constructed as a pull rope, which has a certain amount of room to move. Due to its flexibility, it can more easily adapt to materials of various shapes and sizes. The connector 9 is connected to the lever 7. Through this design, the material will come into contact with the connector 9 and the lever 7 during transportation and feeding. As the material continues to be fed, the connector 9 will pull the limiting plate 8 closer to the center to perform a certain degree of alignment on the material passing by. Then, the lever 7 will swing upward under the action of the rotating rod 15 and pull the connector 9 away from the material to avoid obstructing the material.

[0036] Specifically, refer to Figures 1 to 4 The conveying mechanism includes: a motor 2, a conveyor belt 3, a drive shaft 10, and transmission wheels 11. The motors 2 are all mounted on the surface of the frame 1, the drive shafts 10 are all connected to the output end of the motors 2, the transmission wheels 11 are all mounted on the surface of the drive shafts 10, and the conveyor belt 3 is connected between the transmission wheels 11. In this embodiment, when the motor 2 starts, the torque and speed it generates are transmitted to the transmission wheels 11 through the drive shafts 10. The transmission wheels 11 are in close contact with the inner side of the conveyor belt 3, and the torque and speed of the drive shaft 10 are transmitted to the conveyor belt 3 through friction or meshing. As the transmission wheels 11 rotate, the conveyor belt 3 starts to move and transports the material from one place to another. The inner side of the frame 1 is equipped with a support part 12 located inside the conveyor belt 3 to improve the support strength of the conveyor belt 3.

[0037] Specifically, refer to Figure 1 , Figure 2 and Figure 4 The protective components include: a buffer plate 4, a rotating rod 13, and an elastic element 14. The buffer plate 4 is installed on the inner side of the frame 1 via the rotating rod 13, and the elastic element 14 is connected between the buffer plate 4 and the frame 1. In this embodiment, the material can be supported by the buffer plate 4 during downward feeding, and under the action of gravity, the buffer plate 4 can be rotated via the rotating rod 13 and the elastic element 14 can be compressed, ensuring that the buffer plate 4 can maintain a certain stability and flexibility when subjected to impact, thereby reducing the impact of the material and reducing damage.

[0038] Furthermore, the buffer plate 4 is configured to be inclined downward in the horizontal direction, and one end of the buffer plate 4 is in contact with the conveyor belt 3, so that the buffer plate 4 can also scrape and clean the conveyor belt 3 to a certain extent. Through this design, the inclined buffer plate 4 can naturally guide the material to slide down its surface. When the material falls from a height or is subjected to other external forces, the inclined buffer plate 4 can better disperse and mitigate the impact energy and reduce the damage to the material.

[0039] Working principle: When using this utility model, the material is first loaded and unloaded on the frame 1. With the operation of the conveying mechanism, the motor 2 drives the drive shaft 10 and the transmission wheel 11 to rotate together, so that the conveyor belt 3 rotates together to transport the material. At this time, the material will contact the connecting piece 9 and the lever 7. As the material continues to feed, the connecting piece 9 pulls the limiting plate 8 closer to the center to straighten the material. Then, the lever 7 will swing upward under the action of the rotating rod 15 and pull the connecting piece 9 away from the material to avoid obstructing the material. This allows the material to straighten itself during transmission, which is convenient to operate, improves utilization, and reduces energy consumption. After the material is transported, a buffer plate 4 is connected to the end of the conveyor belt 3 so that the material can be supported by the buffer plate 4 during downward feeding. Under the action of gravity, the buffer plate 4 can be rotated by the rotating rod 13 and compressed to the elastic member 14, thereby reducing the impact of the material and reducing damage. The buffer plate can also be reset after the material is removed, which is more flexible and improves protection.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
