Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a material distribution mechanism. Background Technology

[0002] In industrial automated production, some materials are stored in stacks. During material distribution and conveying, suction cups are typically used. This method is suitable for products with relatively flat surfaces. However, it is not suitable for products with uneven surfaces or those full of through holes, resulting in significant limitations. Therefore, it is necessary to design a material distribution mechanism that can meet the needs of different products. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the prior art by proposing a material distribution mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a material distribution mechanism, comprising: a conveying component, a positioning component suspended on the conveying component, and a top material conveying component located at the lower end of the conveying component and passing through the conveying component, extending to the positioning component; the positioning component includes a discharge bin formed by multiple L-shaped vertical plates, and the bottom of the discharge bin is provided with blocking drive components at different heights and which can move relative to each other to fix the material; the higher blocking drive component blocks the second material at the bottom of the discharge bin, and the lower blocking drive component blocks the first material at the bottom of the discharge bin; the top material conveying component rises to absorb and catch the first material at the bottom of the discharge bin, and the lower blocking drive component moves backward, causing the top material conveying component to descend and move the material downward, thus conveying the first material to the conveying component.

[0005] Furthermore, the conveying component includes a hollowed-out frame, with a rotating shaft at one end of the frame and a fixed shaft at the other end of the frame opposite the rotating shaft. The rotating shaft is provided with a number of main drive wheels that rotate with it at equal intervals. The fixed shaft is provided with a number of driven wheels that are corresponding to the main drive wheels at equal intervals. Each driven wheel rotates around the fixed shaft. Each corresponding main drive wheel and driven wheel is connected to a conveyor belt. The frame is provided with a chain and a motor drive mechanism to drive the rotating shaft to rotate.

[0006] Furthermore, the side wall of the frame connected to both ends of the fixed shaft is provided with a moving groove, and the side wall is also provided with a countersunk hole communicating with the moving groove. The countersunk hole is provided with an adjusting rod that passes through the countersunk hole and connects to the fixed shaft located in the moving groove. One end of the adjusting rod that connects to the fixed shaft is provided with an external thread, and the fixed shaft is provided with a threaded hole that connects to the external thread. The position of the fixed shaft is adjusted by adjusting the adjusting rod to adjust the tension of the conveyor belt.

[0007] Furthermore, the top material conveying component includes a horizontal plate fixed within the frame, with support slide rods on both sides of the horizontal plate slidably connected to the horizontal plate via linear bearings, a receiving plate at the top of the two support slide rods, a suction nozzle on the top of the receiving plate, and a stroke cylinder with its output end passing through the horizontal plate and connected to the receiving plate on the horizontal plate between the two support slide rods.

[0008] Furthermore, the width of the receiving plate is smaller than the distance between the two conveyor belts.

[0009] Furthermore, the positioning component also includes a top plate fixed to the top of the frame, the top plate having a material drop opening, multiple L-shaped vertical plates arranged around the material drop opening, and a material blocking drive assembly fixed to the top plate.

[0010] Furthermore, there are four material blocking drive components, symmetrically arranged in pairs around the material drop port. The two opposite material blocking drive components are of equal height. Each material blocking drive component includes an adjusting connecting plate. The adjusting connecting plate is equipped with a forward-pushing cylinder, and the output end of the forward-pushing cylinder is equipped with a material blocking plate. The adjusting connecting plate is provided with a first strip groove on both sides. The adjusting connecting plate is connected to the top plate by screws passing through the first strip grooves, so that the adjusting connecting plate is fixed to the top plate. The front and rear positions of the adjusting connecting plate can be adjusted by loosening the screws.

[0011] Furthermore, the bottom of the L-shaped vertical plate is provided with a connecting block, and the two sides of the connecting block are provided with a second strip groove. The connecting block is fixed to the top plate by screws passing through the second strip grooves. The front and rear positions of the connecting block can be adjusted by loosening the screws.

[0012] Furthermore, the bottom of the top plate is provided with elastic pads that are connected to the frame.

[0013] Compared with existing technologies, this invention has the following advantages: By setting up a conveying component, a positioning component, and a top-feeding conveying component, materials are piled in the discharge bin. The top-feeding conveying component rises to absorb and catch the first material at the bottom of the discharge bin. A low-height baffle drive component retracts, causing the top-feeding conveying component to descend and move the material downwards. The descending top-feeding conveying component transports the first material to the conveying component, which then transports it to the next workstation, achieving automatic material sorting and conveying. This overcomes the limitations of using suction cups for material sorting and conveying, and is suitable for materials of different shapes and surfaces, improving the flexibility and applicability of material sorting and conveying. The material sorting mechanism of this invention has a simple structure, is easy to operate, and has a high degree of automation, greatly improving production efficiency. Attached Figure Description

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Please see Figure 1 and Figure 2 This embodiment provides a material distribution mechanism, which includes a conveying component 10, a positioning component 20 and a top material conveying component 30. The top material conveying component 30 is located below the conveying component 10, and the positioning component 20 is suspended above the conveying component 10.

[0018] The conveying component 10 is used to convey the material conveyed by the top material conveying component 30 to the next work station. The conveying component 10 includes a hollow frame 101, which is formed by multiple profiles and has four vertical profiles. Other profiles are fixed horizontally and vertically to the four vertical profiles, so that the frame 101 is hollow. Foot cups are installed at the bottom of the four vertical profiles.

[0019] A rotating shaft 102 is provided at one end of the upper side of the frame 101, and a fixed shaft 103 is provided at the other end of the frame 101 opposite to the rotating shaft 102. The rotating shaft 102 has several main drive wheels 104 that rotate with it at equal intervals. The fixed shaft 103 has several driven wheels 105 that correspond to the main drive wheels 104 at equal intervals. Each driven wheel 105 rotates around the fixed shaft 103. Each corresponding main drive wheel 104 and driven wheel 105 is connected to a conveyor belt 106. The frame 101 is provided with a chain and a motor drive mechanism 107 to drive the rotating shaft 102 to rotate. The chain and motor drive mechanism 107 drive the rotating shaft 102 to rotate, thereby driving the main drive wheels 104 to rotate. The conveyor belt 106 forms a closed loop between the main drive wheels 104 and the driven wheels 105. As the main drive wheels 104 rotate, the conveyor belt 106 also moves accordingly, realizing the conveying of materials.

[0020] The positioning component 20 is used to store materials and cooperate with the top material conveying component 30 to convey the materials one by one to the conveyor belt 106. The positioning component 20 includes a top plate 201 fixed to the top of four vertically set profiles. The bottom of the top plate 201 is provided with an elastic pad connected to the frame 101. The top plate 201 has a material drop port, and multiple L-shaped vertical plates 202 are arranged around the material drop port on the top plate 201. The multiple L-shaped vertical plates 202 form a material discharge bin, which can place stacked materials in the material discharge bin. The bottom of the material discharge bin is provided with a material blocking drive component 203, which is fixed to the top plate 201.

[0021] The device includes four material blocking drive components 203, symmetrically arranged in pairs around the discharge port. The two opposing material blocking drive components 203 are of equal height. The two taller material blocking drive components 203 block the second piece of material at the bottom of the discharge hopper, while the shorter material blocking drive components block the first piece of material at the bottom of the discharge hopper. Each material blocking drive component 203 includes an adjusting connecting plate 2031, on which a forward-pushing cylinder 2032 is mounted. A baffle plate 2033 is mounted at the output end of the forward-pushing cylinder 2032. The adjusting connecting plate 2031 has first strip-shaped grooves on both sides, which are connected to the top plate 201 by screws passing through them, thus fixing the adjusting connecting plate 2031 to the top plate 201. By loosening the screws, the front and rear positions of the adjusting connecting plate 2031 can be adjusted, allowing the baffle plate 2033 to slide along the bottom of the discharge hopper to block and release the material. When the current push cylinder 2032 extends, the baffle plate 2033 moves forward to block the material from moving downward; when the current push cylinder 2032 retracts, the baffle plate 2033 retracts, allowing the material to move downward. This design allows the baffle drive assembly 203 to precisely control the material conveying sequence, ensuring that only one piece of material is conveyed onto the conveyor belt 106 at a time. Furthermore, by adjusting the design of the first slot and screws on the connecting plate 2031, the position of the baffle drive assembly 203 can be easily adjusted to accommodate materials of different sizes, improving the flexibility and applicability of the material distribution mechanism.

[0022] In an optional embodiment, the bottom of the L-shaped vertical plate 202 is provided with a connecting block 2021, and the connecting block 2021 is provided with a second strip groove on both sides. The connecting block 2021 is connected to the top plate 201 by screws passing through the second strip grooves, so that the connecting block 2021 is fixed to the top plate 201. By loosening the screws, the front and rear positions of the connecting block 2021 can be adjusted. The adjustable L-shaped vertical plate 202 design allows the material distribution mechanism to adapt to more types of materials and different production needs, improving the versatility and practicality of the material distribution mechanism.

[0023] The top material conveying component 30 is used to convey the material at the bottom of the discharge bin to the conveyor belt 106. The top material conveying component 30 includes a horizontal plate 301 fixed in the frame 101. Supporting slide rods 302 are provided on both sides of the horizontal plate 301 through linear bearings and slidably connected to the horizontal plate 301. The top of the two supporting slide rods 302 is provided with a receiving plate. A suction nozzle is provided on the top of the receiving plate to absorb the bottom surface of the material. The horizontal plate 301 between the two supporting slide rods 302 is provided with a stroke cylinder 303 whose output end passes through the horizontal plate 301 and is connected to the receiving plate. The width of the receiving plate is smaller than the distance between the two conveyor belts 106. The extension and retraction of the stroke cylinder 303 causes the receiving plate to slide up and down on the supporting slide rods 302. When the stroke cylinder 303 extends, the receiving plate moves upward, extends into the bottom of the discharge bin, contacts the material, supports the material, and the suction nozzle adsorbs the bottom surface of the material. When the stroke cylinder 303 retracts, the receiving plate carries the material downward, and the suction nozzle pulls the material, separating sticky or tightly adhered materials. Because the second material is driven by the high-height baffle drive component 203, the second material will not be pulled when the first material is pulled, until the first material is conveyed onto the conveyor belt 106. This design of the top material conveying component 30 ensures that the material can be smoothly and accurately conveyed from the bottom of the discharge bin onto the conveyor belt 106, and can effectively separate sticky or tightly adhered materials. At the same time, the width of the receiving plate is smaller than the distance between the two conveyor belts 106, which allows the receiving plate to accurately place the material on the conveyor belt 106 without interfering with the operation of the conveyor belt 106, improving the conveying efficiency and accuracy of the material distribution mechanism.

[0024] In an optional embodiment, when conveying heavy materials, the conveyor belt 106 is prone to deformation, requiring tensioning to ensure smooth transport. To address this, a movable groove 1011 is provided on the side wall of the frame 101 connected to both ends of the fixed shaft 103. A countersunk hole communicating with the movable groove 1011 is also provided on the side wall. The countersunk hole has an adjusting rod that passes through and connects to the fixed shaft 103 located within the movable groove 1011. One end of the adjusting rod connected to the fixed shaft 103 has an external thread, and the fixed shaft 103 has a threaded hole connected to the external thread. Adjusting the position of the fixed shaft 103 with the adjusting rod adjusts the tension of the conveyor belt 106. When tensioning the conveyor belt 106 is required, the operator rotates the adjusting rod, causing the fixed shaft 103 to move along the front end of the movable groove 1011 (i.e., move away from the rotating shaft 102), thereby adjusting the tension of the conveyor belt 106. Conversely, when it is necessary to loosen the conveyor belt 106, the adjusting lever is rotated in the opposite direction, causing the fixed shaft 103 to move along the rear end of the moving groove 1011 (i.e., towards the rotating shaft 102), thereby loosening the conveyor belt 106. This design allows operators to easily adjust the tension of the conveyor belt 106 according to actual conditions, effectively avoiding deformation of the conveyor belt 106 caused by heavy materials, ensuring smooth conveying of the conveyor belt 106, and improving the stability and durability of the material distribution mechanism.

[0025] In summary, when the operator places the stacked materials into the discharge hopper, during the material conveying process, the stroke cylinder 303 extends, pushing the receiving plate upwards and extending into the bottom of the discharge hopper. This causes the first material at the bottom layer to be adsorbed on the receiving plate. When the lower-profile forward-pushing cylinder 2032 retracts, the baffle plate 2033 retracts, causing the first material at the bottom layer to fall onto the receiving plate. At this time, the stroke cylinder 303 retracts, and the receiving plate pulls the material, separating the first and second materials that are stuck together, carrying the first material downwards. When the material is in its lower position, the lower-height forward-pushing cylinder 2032 resets, causing the baffle plate 2033 to extend, while the higher-height forward-pushing cylinder 2032 retracts, allowing the second material at the bottom to fall onto the lower-height baffle plate 2033. The higher-height forward-pushing cylinder 2032 then extends the baffle plate 2033 and moves forward, preventing the third material from moving downwards. Simultaneously, the stroke cylinder 303 retracts until the material is conveyed onto the conveyor belt 106, and then transported to the next workstation via the conveying component 10. This entire process is repeated cyclically, achieving automatic material sorting and conveying. Furthermore, this sorting mechanism is rationally designed, simple in structure, and easy to operate and maintain, greatly improving production efficiency and quality. Moreover, by adjusting the positions of each component, this sorting mechanism can adapt to materials of different sizes and types, exhibiting wide applicability.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
