Description

Technical Field

[0001] This utility model relates to the field of material conveying and unloading technology, and in particular to an unloading buffer device. Background Technology

[0002] In industries such as food processing and pharmaceutical manufacturing, washing baskets are commonly used as containers for loading and cleaning materials. Traditionally, after washing, the baskets require manual unloading. This involves transporting the baskets to a designated location, where operators manually open the basket lids and empty the materials. Due to the large quantity and weight of materials in the baskets, manual operation is not only labor-intensive and inefficient, but also prone to instability, spillage, or damage. Furthermore, directly dumping materials can cause breakage or deformation due to the high impact force, affecting product quality. Therefore, there is an urgent need for a feeding device that can automatically unload materials and has a buffer function to improve the automation and safety of the feeding process. Utility Model Content

[0003] The purpose of this invention is to provide a feeding buffer device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding buffer device, comprising a support, a motor mounted on the support, a reducer connected to the motor, a first rotating shaft mounted on the reducer, a first gear fixed on the first rotating shaft, and a first chain meshing with the first gear; the support also comprises two bearing seats, through which a second rotating shaft is passed, a second gear and a third gear fixed on the second rotating shaft, the second gear meshing with the first chain, and the third gear meshing with a second chain on a washing basket; the support also comprises multiple baffles, which together form a feeding bin with a top opening, and a hopper hinged to the bottom of the feeding bin; the hopper comprises a first side plate, a second side plate, and a bottom plate, with multiple buffer plates spaced apart between the first and second side plates, each buffer plate having a counterweight at its upper part, and the included angle between the buffer plate and the bottom plate being 80-90°; the hopper comprises a flap and a supporting beam, with a connecting plate in the middle of the supporting beam, and a cylinder connected to the connecting plate.

[0005] Preferably, the cylinder is provided with a cylinder rod, one end of the cylinder is provided with a first air connector, and the other end of the cylinder is provided with a second air connector. The first air connector and the second air connector are used to connect to an air pipe.

[0006] Preferably, the top of the cylinder is provided with a fixing bracket, which is fixed to the frame.

[0007] Preferably, the buffer plate is fixedly connected to a sleeve, and a fixing rod is fitted inside the sleeve. The two ends of the fixing rod are respectively fixed to the first side plate and the second side plate.

[0009] Preferably, a silicone curtain is provided at the outlet of the hopper.

[0010] Preferably, the bottom of the feeding hopper is hinged to the hopper via multiple hinges.

[0011] Compared with existing technologies, this utility model provides a material feeding buffer device with the following advantages: automatic material feeding is achieved by driving the washing basket to rotate with a motor. Combined with multiple buffer plates with counterweights inside the hopper, multi-stage buffering is formed during material descent, effectively slowing down the material flow rate and preventing material damage caused by direct impact. Limiting rods prevent excessive overturning of the buffer plates, ensuring they remain in an effective material-blocking state.

[0014] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model: like Figure 1-8 As shown, the present invention provides a material feeding buffer device, including a bracket 1, which serves as the supporting structure for the entire device, ensuring the stable installation of all components. A motor 2 is mounted on the bracket 1, serving as the power source. The motor 2 is connected to a reducer 3, which reduces the output speed and increases the torque to ensure smooth transmission. A first rotating shaft 4 is mounted on the reducer 3, and a first gear 41 is fixed on the first rotating shaft 4. A first chain 411 meshes with the first gear 41, forming a primary transmission mechanism for transmitting power.

[0015] The bracket 1 is also equipped with two bearing seats 5, through which a second rotating shaft 6 is driven. A second gear 61 and a third gear 62 are fixed on the second rotating shaft 6. The second gear 61 meshes with the first chain 411 to achieve two-stage power transmission; the third gear 62 meshes with the second chain 71 on the washing basket 7, thereby driving the washing basket 7 to rotate and achieve automatic unloading. This transmission mechanism has a compact structure, high transmission efficiency, effectively replaces traditional manual operation, and significantly improves unloading efficiency.

[0016] The support frame 1 is also equipped with multiple baffles 8, which together form a top-opening discharge bin 9 to receive materials poured from the washing basket 7 and prevent material spillage. The bottom of the discharge bin 9 is hinged to a hopper 10 via multiple hinges 19, allowing the hopper 10 to rotate within a certain angle range, which facilitates control of the material flow.

[0017] The hopper 10 includes a first side plate 101, a second side plate 102, and a bottom plate 103, which together form a channel for material flow. Multiple buffer plates 11 are spaced apart between the first side plate 101 and the second side plate 102. Each buffer plate 11 has a counterweight 111 on its upper part, and the angle between the buffer plate 11 and the bottom plate 103 is 80-90°. The buffer plates 11 automatically reset via the counterweights 111 on their upper parts, providing multi-stage buffering when materials fall, effectively reducing the material flow rate and preventing material damage caused by impact.

[0018] A sleeve 16 is fixedly connected to the buffer plate 11. A fixing rod 161 is fitted inside the sleeve 16. The two ends of the fixing rod 161 are fixed to the first side plate 101 and the second side plate 102 respectively by L-shaped fasteners 20. This structure allows the buffer plate 11 to swing around the fixing rod 161 within a certain angle, achieving dynamic buffering. To prevent the buffer plate 11 from overturning due to the counterweight 111, multiple limiting rods 17 are also provided at intervals between the first side plate 101 and the second side plate 102. Each limiting rod 17 corresponds to one buffer plate 11 and is located beside the buffer plate 11. The buffer plate 11 is positioned between the fixing rod 161 and the limiting rod 17. The function of the limiting rod 17 is to limit the swing range of the buffer plate 11, ensuring that it does not overturn under the impact of materials and always maintains an effective material blocking state.

[0019] A silicone curtain 18 is provided at the outlet of the hopper 10. The silicone curtain 18 is soft and can further slow down the material flow rate and prevent material from splashing at the outlet. A flap 12 is provided on the hopper 10 to control the material drop speed. A support beam 13 is also provided on the hopper 10. A connecting plate 14 is provided in the middle of the support beam 13. The connecting plate 14 is connected to a cylinder 15 through a horizontal shaft 141. A cylinder rod 151 is provided inside the cylinder 15. A first air connector 152 is provided at one end of the cylinder 15, and a second air connector 153 is provided at the other end of the cylinder 15. The first air connector 152 and the second air connector 153 are used to connect air pipes to realize the extension and retraction control of the cylinder 15. A fixing bracket 154 is provided on the top of the cylinder 15. The fixing bracket 154 is fixed to the frame to ensure that the cylinder 15 is firmly installed. When the cylinder rod 151 extends downward, it pushes the hopper 10 to tilt downward around the hinge point of the hinge 19, so that the material flows out in an orderly manner under the action of gravity.

[0020] The working process of this utility model is as follows: The washing basket 7 is grasped by the robotic arm and placed above the feeding bin 9. The motor 2 starts and outputs power. The power of the motor 2 is adjusted and increased in torque by the reducer 3, driving the first rotating shaft 4 and the first gear 41 on it to rotate. The first gear 41 transmits power to the second gear 61 through the first chain 411 meshing with it. The second gear 61 drives the second rotating shaft 6 to rotate synchronously in the bearing seat 5, and the third gear 62 fixed on the same second rotating shaft 6 moves accordingly. The third gear 62 meshes with the second chain 71 on the washing basket 7, thereby driving the washing basket 7 to rotate, so that the material falls evenly into the feeding bin 9. The material enters the hopper 10 through the feeding bin 9, and multi-stage deceleration is achieved under the action of multiple buffer plates 11, effectively reducing impact. When cylinder 15 is activated, cylinder rod 151 extends downwards, pushing hopper 10 downwards around hinge point 19 via connecting plate 14 and support beam 13. Under gravity, the material, after its flow rate is controlled by flap 12, finally falls out through silicone curtain 18, completing the entire automatic unloading process. The entire process achieves fully automated control from automatic unloading of basket 7 to material flowout, requiring no manual intervention. This significantly improves unloading efficiency and operational safety, making it suitable for high-standard production environments in industries such as food and pharmaceuticals.
