Description

Technical Field

[0001] This utility model belongs to the field of rice wine production technology, specifically relating to a conveyor belt tension adjustment conveyor device. Background Technology

[0002] In the rice wine production industry, efficient conveying devices are a core element to ensure the smooth operation of the entire production process. To effectively solve the problem of rice wine products accumulating after transportation, oscillating conveyor devices have emerged. These devices can transport rice wine products to the storage area more evenly by oscillating the conveyor belt back and forth, playing an important role in improving transportation efficiency and alleviating product accumulation.

[0003] However, existing rice wine conveying devices exhibit significant drawbacks over long-term use. The conveyor belt is continuously subjected to tensile and frictional forces, causing its tension to gradually decrease. This results in a substantial reduction in friction between the conveyor belt and the drive rollers, making it difficult for the drive rollers to drive the conveyor belt for normal transport, thus impacting the conveying efficiency of the rice wine product. To address these issues, we provide a conveyor belt tension adjustment device. Utility Model Content

[0029] Specifically, in this embodiment, the base 1 is the basic support structure of the overall device and has a strong load-bearing capacity. The mounting frame 2 above the base 1 is connected to the output end of the drive mechanism 11 on the upper surface of the base 1, ensuring that the mounting frame 2 can swing and rotate flexibly under the action of the drive mechanism 11. On the inner wall of the mounting frame 2, a first transmission roller 3 and a second transmission roller 4 are rotatably connected, and the two are arranged in parallel. A conveyor belt 5 is sleeved on the outer surface of the first transmission roller 3 and the second transmission roller 4, so that the first transmission roller 3 and the second transmission roller 4 are connected by transmission through the conveyor belt 5. The support roller 6 is arranged below the conveyor belt 5, and its outer surface is closely attached to the outer surface of the conveyor belt 5 to provide auxiliary support for the conveyor belt 5. The tensioning component 7 installed on the inner wall of the mounting frame 2 is located inside the conveyor belt 5 and is used to adjust the tension of the conveyor belt 5. The tensioning component 7 includes a tensioning roller 701, which is arranged inside the conveyor belt 5 and its outer surface is attached to the inner surface of the conveyor belt 5.

[0030] Please see Figure 4As shown, the tensioning assembly 7 includes a tensioning roller 701, which is located inside the conveyor belt 5 and is in contact with the inner surface of the conveyor belt 5. The tensioning assembly 7 also includes a mounting housing 702, which is fixedly connected to the inner wall of the mounting frame 2. A motor 703 is fixedly connected to the inner top wall of the mounting housing 702, and a lead screw 704 is fixedly connected to the output end of the motor 703. The lower end of the lead screw 704 is rotatably connected to the inner bottom wall of the mounting housing 702. A connecting plate 705 is threaded onto the outer surface of the lead screw 704. Two limiting slide rods 706 are fixedly connected to the inner wall of the mounting housing 702, symmetrically distributed on the left and right sides of the lead screw 704. The connecting plate 705 is slidably connected to the outer surface of the two limiting slide rods 706, and two connecting rods 707 are fixedly connected to the bottom surface of the connecting plate 705. The lower ends of both connecting rods 707 extend to the bottom of the mounting housing 702. The lower ends of the two connecting rods 707 are fixedly connected to a connecting frame 708, and the tension roller 701 is rotatably connected to the inner wall of the connecting frame 708.

[0031] Specifically, in this embodiment, the mounting shell 702 of the tensioning assembly 7 is fixedly connected to the inner wall of the mounting bracket 2, providing installation space and support for other components of the tensioning assembly 7. The motor 703 installed inside the mounting shell 702 is controlled by an external control switch. The operation of the motor 703 can drive the lead screw 704 to rotate. The connecting plate 705 is threadedly connected to the outer surface of the lead screw 704, and is slidably connected to the outer surface of the two limiting slide rods 706. Therefore, the rotation of the lead screw 704 can drive the connecting plate 705 to move on the limiting slide rods 706.

The cleaning brush 1003 is located below the conveyor belt 5 and is in contact with the outer surface of the conveyor belt 5. A collection frame 1004 is provided inside the cleaning groove 1001. In this embodiment, the cleaning groove 1001 in the cleaning assembly 10 is located below the mounting frame 2, and threaded holes are provided on both its left and right sides. Two fixing screws 1002 are used to connect and fix the cleaning groove 1001 to the threaded holes reserved on the bottom surface of the mounting frame 2. This design facilitates the disassembly and installation of the cleaning groove 1001. The cleaning brush 1003 is located below the conveyor belt 5, and its bristles are in close contact with the outer surface of the conveyor belt 5. Inside the cleaning groove 1001, a collection frame 1004 is placed to collect the dirt swept down from the outer surface of the conveyor belt 5 by the cleaning brush 1003. The collection frame 1004 can be pulled out from the cleaning groove 1001 to facilitate the cleaning of the dirt accumulated in the collection frame 1004.

[0034] Please see Figure 6 As shown, a drive mechanism 11 is mounted on the upper surface of the base 1, and a mounting frame 2 is mounted on the output end of the drive mechanism 11. The mounting frame 2 is rotatably connected to the base 1 via the drive mechanism 11. An auxiliary component 12 is mounted on the bottom surface of the mounting frame 2. The auxiliary component 12 includes a support column 1201, which is fixedly connected to the bottom surface of the mounting frame 2. A base plate 1202 is fixedly connected to the lower end of the support column 1201. A plurality of ball bearings 1203 are rolled together on the bottom surface of the base plate 1202. The ball bearings 1203 are distributed in a ring on the bottom surface of the base plate 1202, and all of the ball bearings 1203 are in contact with the upper surface of the base 1. In this embodiment, the drive mechanism 11 is a rotating output device composed of a motor and a linkage mechanism. The mounting frame 2 is mounted on the output end of the drive mechanism 11. The operation of the drive mechanism 11 allows the mounting frame 2 to swing left and right. The auxiliary component 12 is mounted on the bottom surface of the mounting frame 2. The support column 1201 in the auxiliary component 12 is fixedly connected to the bottom surface of the mounting frame 2. The bottom surface of the base plate 1202 is fixedly connected to the lower end of the support column 1201. Multiple ball bearings 1203 are rolled together in a ring. The multiple ball bearings 1203 are all in contact with the upper surface of the base 1. During the swinging process of the mounting frame 2, the ball bearings 1203 roll, providing auxiliary support for the swinging of the mounting frame 2 and ensuring that the swinging of the mounting frame 2 is stable.

[0035] In this embodiment, six support legs 13 are fixedly connected to the bottom surface of the base 1. The six support legs 13 are rectangularly distributed on the bottom surface of the base 1, evenly supporting the base 1 and ensuring that the entire device is placed stably, providing basic support for the stable operation of the device. During use, turning on motor 29 drives transmission roller 3 to rotate. Transmission roller 3 is connected to transmission roller 24 via conveyor belt 5, thus driving conveyor belt 5 to rotate. The rice wine product to be transported is placed on conveyor belt 5. Simultaneously, the drive mechanism 11 is activated via an external control switch, causing the mounting frame 2 and the internal conveyor belt 5 to swing back and forth. During the swinging process of mounting frame 2, support column 1201 moves accordingly, and the ball bearings 1203 provide auxiliary support for the swinging of mounting frame 2, ensuring stable swinging. Then, the rice wine product is transported to the storage area via conveyor belt 5 to avoid product accumulation. At the same time, the cleaning brush 1003 on the bottom of mounting frame 2 cleans the outer surface of conveyor belt 5 as it rotates, sweeping off the attached dirt and letting it fall into the collection box 1004 in the cleaning trough 1001. During long-term operation of the equipment, if the conveyor belt is found to be faulty, the cleaning brush will be activated. If slack occurs, the motor 703 in the tensioning assembly 7 is activated by an external control switch, which drives the lead screw 704 to rotate. Since the lead screw 704 is threadedly connected to the connecting plate 705, and the connecting plate 705 is slidably connected to the outer surface of the two limiting slide rods 706, the rotation of the lead screw 704 can drive the connecting plate 705 to move downward along the axial direction of the lead screw 704 under the restriction of the limiting slide rods 706. Then, through the two connecting rods 707 and the connecting frame 708, the tensioning roller 701 is driven to move downward steadily, applying pressure to the inner side of the conveyor belt 5. With the coordinated support of the transmission roller 3, the transmission roller 4 and the support roller 6, the conveyor belt 5 is stretched and tightened, and the tension is restored to a suitable level. After the equipment has been running for a period of time, the collection frame 1004 can be pulled out from the cleaning trough 1001 to clean the dirt accumulated in the collection frame 1004. After cleaning, the collection frame 1004 can be put back into the cleaning trough 1001.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
