Description

Technical Field

[0001] This utility model belongs to the field of eel feed production technology, specifically relating to an automatic weighing and packaging device for eel feed production. Background Technology

[0002] In the large-scale production of eel feed, weighing and packaging are key steps to ensure product quality stability and improve production efficiency. Currently, most eel feed manufacturers in the industry still use the traditional model of manual weighing combined with semi-mechanical packaging. This involves first manually operating a platform scale to weigh the feed, then manually pouring the weighed feed into packaging boxes, and finally tightening the box lids with simple machinery or purely manual labor.

[0003] However, manual weighing is easily affected by human factors such as operator skill and fatigue, making it difficult to guarantee the accurate and consistent weight of each box of feed.

[0004] Secondly, the weighing and packaging process relies on manual handling, resulting in a low level of automation. This not only requires a significant investment in manpower but also leads to low production efficiency, making it impossible to meet the production capacity demands of large-scale eel feed production. Utility Model Content

[0005] The purpose of this invention is to provide an automatic weighing and packaging device for eel feed production, which can integrate feeding weighing and packaging box capping to ensure that the weight of each box of eel feed is accurate and consistent, thereby improving product quality consistency.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An automatic weighing and packaging device for eel feed production includes a conveyor belt body and a box body. A lifting component is provided between the conveyor belt body and the box body. A box cover is hinged to the top surface of the box body. Two tightening wheels are symmetrically arranged on the left and right sides of the bottom surface of the box body. An elongated hole corresponding to the tightening wheel is opened on the bottom surface of the box body. Two mounting plates are provided in the inner cavity of the box body. A rotating shaft is fixedly connected to the top of each tightening wheel. The rotating shaft passes through the elongated hole and is rotatably connected to the mounting plate. Two first cylinders are fixedly installed on the inner wall of the box body. The telescopic ends of the first cylinders are fixedly connected to the mounting plates.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-5 As shown, an automatic weighing and packaging device for eel feed production includes a conveyor belt body 1 and a box body 2. A lifting component is provided between the conveyor belt body 1 and the box body 2. A box cover 3 is hinged to the top surface of the box body 2. Two tightening wheels 7 are symmetrically arranged on the left and right sides of the bottom surface of the box body 2. An elongated hole 8 corresponding to the tightening wheel 7 is opened on the bottom surface of the box body 2. When the tightening wheel 7 moves, the elongated hole 8 is used for limiting the movement. Two mounting plates 9 are provided in the inner cavity of the box body 2. A rotating shaft is fixedly connected to the top of each tightening wheel 7. The rotating shaft passes through the elongated hole 8 and is rotatably connected to the mounting plate 9. Two first cylinders 10 are fixedly installed on the inner wall of the box body 2. The telescopic ends of the first cylinders 10 are fixedly connected to the mounting plate 9. A transmission component is provided on the right mounting plate 9.

[0027] The inner cavity of the box body 2 is fixedly connected to the feed pipe 11, and the top surface of the box cover 3 is provided with a through hole. The two ends of the feed pipe 11 pass through the box body 2, and the inner cavity of the feed pipe 11 is provided with a weighing component.

[0028] like Figure 1 As shown, the lifting assembly includes two brackets 4 fixedly connected to the top of the conveyor belt body 1. A second cylinder 5 is fixedly installed on the top surface of each bracket 4. Fixing plates 6 are fixedly connected to the left and right side walls of the housing 2 respectively. The extension and retraction ends of the second cylinder 5 are fixedly connected to the fixing plates 6.

[0029] Among them, the support 4 has a U-shaped structure, and the box 2 is located inside the support 4. The support 4 provides load-bearing capacity for the box 2 and the second cylinder 5, which facilitates the overall lifting and lowering of the box 2 and the tightening wheel 7, and can adapt to packaging boxes of different heights.

[0030] like Figure 3 As shown, the transmission assembly includes a support plate 12 fixedly connected to the side wall of the right mounting plate 9. A motor 13 is fixedly connected to the top surface of the support plate 12. Grooved wheels 14 are fixedly connected to the top ends of the two rotating shafts on the right side. A belt 15 is connected between the two grooved wheels 14. The output end of the motor 13 is fixedly connected to one of the grooved wheels 14.

[0031] Specifically, the four tightening wheels 7 are arranged in pairs. The two tightening wheels 7 on the right are driving wheels, which provide rotational power to drive the lid to rotate. The two tightening wheels 7 on the left are driven wheels, which can drive the lid to rotate synchronously when the lid rotates, and at the same time play a limiting role in the lid, ensuring that the lid can be tightened smoothly.

[0032] like Figure 5 As shown, the weighing assembly includes a support plate 17 disposed in the inner cavity of the feed pipe 11, a drive shaft 21 fixedly connected to the side wall of the support plate 17, the drive shaft 21 being rotatably connected to the feed pipe 11, a weighing sensor 18 mounted on the top surface of the support plate 17, a weighing plate 16 fixedly connected to the top of the weighing sensor 18, and a flipping drive assembly disposed on the side wall of the feed pipe 11.

[0033] like Figure 4 As shown, the flipping drive assembly includes a gear 22 fixedly connected to the side wall of the transmission shaft 21 located outside the feed pipe 11. A rack 20 meshes with the lower side of the gear 22. A transmission plate 19 is fixedly connected to the side wall of the right mounting plate 9. One end of the rack 20 is fixedly connected to the transmission plate 19.

[0034] The weighing sensor 18 is a mature existing technology. In actual use, the area above the weighing plate 16 is a temporary storage area for materials. The weighing sensor 18 can determine the weight of the materials in a timely manner, making it convenient to control the packaging weight of the feed. The weighing sensor 18 is connected to the back-end system. At the same time, feed is fed into the feed pipe 11 using an external feeding device. The external feeding device is connected to the feed pipe 11 and can be equipped with an electric valve, which is linked with the weighing sensor 18. When the weight reaches the target, the electric valve closes immediately. When the packaging box is detected to have moved to the bottom of the feed pipe 11, the bearing plate 17 can be flipped using the linkage of the gear 22 and the rack 20 to discharge the feed into the packaging box, achieving the purpose of weighing and feeding in one step. The operator only needs to put the lid on the packaging box, resulting in high production efficiency.

[0035] like Figure 5 As shown, an extension tube 23 is slidably connected inside the feed pipe 11, and a bolt 24 is threadedly connected to the side wall of the feed pipe 11.

[0036] The extension tube 23 has a positioning groove on its side wall, and the bolt 24 abuts against the side wall of the positioning groove.

[0037] To increase adaptability during feeding, an extension tube 23 is installed inside the feed pipe 11 to supplement small-capacity, small-volume packaging boxes, making it easier to accurately put feed into the packaging boxes, reducing the probability of feed spillage, and fixing it with bolts 24, which is convenient to operate and highly stable.

[0038] The working principle of this utility model is as follows: packaging boxes are placed on the conveyor belt body 1 in sequence. As the conveyor belt body 1 is conveyed, when the packaging box moves to the bottom of the feed pipe 11, feed is injected into the feed pipe 11 through external equipment, and the weight of the material on the weighing plate 16 is monitored in real time by the weighing sensor 18. When the weight reaches the set value, the feeding is stopped.

[0039] Next, the second cylinder 5 is started to move the box body 2 downward, so that the feed pipe 11 is located on the upper side of the packaging box. The first cylinder 10 is started. The first cylinder 10 pushes the tightening wheel 7 to move a short distance through the mounting plate 9. At the same time, the mounting plate 9 drives the transmission plate 19 to move. The transmission plate 19 drives the rack 20 to move, so that the rack 20 meshes with the gear 22 and drives the bearing plate 17 and the weighing plate 16 to rotate 90° through the transmission shaft 21. The material on the weighing plate 16 enters the packaging box through the feed pipe 11, and the box lid is put on the packaging box manually.

[0040] Then the first cylinder 10 continues to move, driving the four tightening wheels 7 to press tightly against the box lid. The motor 13 is started, and the output shaft of the motor 13 drives the side groove wheel 14 to rotate. The side groove wheel 14 drives the other side groove wheel 14 to rotate through the belt 15, so that the two tightening wheels 7 on the right side rotate synchronously, tightening the box lid onto the packaging box, achieving the purpose of rapid packaging.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
