Description

Technical Field

[0001] This utility model relates to the field of beverage can manufacturing technology, and more specifically, to a chain conveyor structure for packaging beverage can lids. Background Technology

[0002] In the production and packaging process of easy-open lids, an efficient, stable, and flexible conveying system is crucial for improving production efficiency and ensuring packaging quality.

[0003] Traditional easy-open lid conveying methods often have many shortcomings. While some simple conveyor belt structures can achieve basic material transport, they are not efficient in space utilization, struggle to adapt to complex production layouts, and cannot flexibly adjust the conveying path according to actual production needs. Furthermore, the lack of an effective buffering mechanism when the supply and packaging speeds of easy-open lids are mismatched can easily lead to production interruptions or chaos.

[0004] Meanwhile, insufficient attention has been paid to the stability of the load-bearing structure during the conveying process. When the load changes, problems such as swaying can easily occur, affecting the placement and safe conveying of the easy-open lids. In addition, traditional conveying devices are difficult to adjust the storage capacity according to changes in production scale, and cannot well meet the diverse needs of different production scenarios. Therefore, those skilled in the art have provided a chain conveyor structure for easy-open lid packaging to solve the above-mentioned problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a chain conveyor structure for easy-open lid packaging.

[0006] To solve the above problems, the present invention adopts the following technical solution;

[0007] A chain conveyor structure for easy-open lid packaging includes a mounting bracket. Evenly distributed drive sprockets are rotatably connected to the inner wall of the mounting bracket. A synchronous shaft is fixedly connected to the opposite side of each drive sprocket. A drive motor is fixedly mounted on the mounting bracket and connected to the synchronous shaft at the top. Two drive chains are arranged inside the mounting bracket, meshing with drive sprockets fitted on the same side. Evenly distributed clamping plates are fixedly mounted on the opposite sides of the two drive chains. Gravity plates are rotatably connected to the clamping plates. Evenly distributed bearing strips are arranged inside the mounting bracket, with the bottom ends of the bearing strips respectively mounted on the tops of the two opposite gravity plates.

[0008] As a further description of the above technical solution: two limiting sprockets are rotatably connected to the inner wall of the mounting bracket, and the limiting sprockets are located at the top of the transmission chain and mesh with the transmission chain.

[0009] As a further description of the above technical solution: uniformly distributed ear plates are fixedly installed on the outer side of the mounting bracket, and an adjusting shaft is threadedly connected to the ear plates, with a mounting plate connected to the bottom end of the adjusting shaft.

[0010] As a further description of the above technical solution: a speed reducer is fixedly installed on the mounting bracket, the output shaft of the speed reducer is connected to the synchronous shaft at the top, and the drive motor is connected to the speed reducer.

[0011] As a further description of the above technical solution: a rotating shaft is connected to the connection position between the gravity plate and the card plate, and the connection position between the rotating shaft and the card plate is lubricated.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] In this invention, the cooperation of the transmission sprocket, the limiting sprocket, and the transmission chain enables the chain to rotate in an L-shape, effectively utilizing space and achieving a flexible conveying path. Furthermore, the gravity plate and the clamping plate are connected by a lubricated rotating shaft, allowing for adaptive adjustment based on the weight of the load-bearing bar, maintaining its stability and ensuring smooth conveying. This not only enables orderly conveying but also provides buffering when supply and packaging speeds differ. Additionally, the top of the mounting bracket can be extended, allowing for changes in the number of transmission sprockets to alter the chain length and thus the storage capacity. This allows for flexible adjustment according to actual needs, making it highly adaptable. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, a chain conveyor structure for easy-open lid packaging includes a mounting bracket 1. A uniformly distributed transmission sprocket 2 is rotatably connected to the inner wall of the mounting bracket 1. A synchronous shaft 3 is fixedly connected to the opposite side of the opposing transmission sprocket 2. A drive motor 4 is fixedly mounted on the mounting bracket 1 and connected to the synchronous shaft 3 at the top. Two transmission chains 5 are arranged inside the mounting bracket 1, and the transmission chains 5 mesh with the transmission sprocket 2 sleeved on the same side. A uniformly distributed clamping plate 6 is fixedly mounted on the opposite side of the two transmission chains 5. A gravity plate 7 is rotatably connected to the clamping plate 6. A uniformly distributed bearing strip 8 is arranged inside the mounting bracket 1, and the two ends of the bottom of the bearing strip 8 are respectively mounted on the top of the two opposing gravity plates 7.

[0022] Two limiting sprockets 10 are rotatably connected to the inner wall of the mounting bracket 1. The limiting sprockets 10 are located at the top of the transmission chain 5 and mesh with the transmission chain 5.

[0023] A reducer 14 is fixedly mounted on the mounting bracket 1. The output shaft of the reducer 14 is connected to the synchronous shaft 3 at the top. The drive motor 4 is connected to the reducer 14.

[0024] A rotating shaft 15 is connected to the connection between the gravity plate 7 and the clamping plate 6, and the connection between the rotating shaft 15 and the clamping plate 6 is lubricated.

[0025] First, the user starts the drive motor 4, which starts running and transmits power to the reducer 14. The reducer 14 adjusts and reduces the speed output by the drive motor 4 to make it output a more suitable speed and torque. Then, the power is transmitted to the top synchronous shaft 3 through the output shaft of the reducer 14.

[0026] Synchronous shaft 3 starts to rotate. Since the opposite side of the transmission sprocket 2 is fixedly connected to synchronous shaft 3, synchronous shaft 3 drives transmission sprocket 2 to rotate synchronously. The transmission sprockets 2 evenly distributed on the inner wall of mounting bracket 1 rotate together. The transmission chain 5 meshes with the transmission sprocket 2 sleeved on the same side. Therefore, the rotation of transmission sprocket 2 drives transmission chain 5 to start moving.

[0027] During the movement of the transmission chain 5, the two limiting sprockets 10 rotatably connected on the inner wall of the mounting bracket 1 play a role. The limiting sprockets 10 are located at the top of the transmission chain 5 and mesh with the transmission chain 5. Through the combined action of multiple transmission sprockets 2 and limiting sprockets 10, the transmission chain 5 is limited to an L state, so that the transmission chain 5 can rotate in an L state.

[0028] Two drive chains 5 are fixedly mounted on opposite sides with evenly distributed clamping plates 6. As the drive chains 5 move, the clamping plates 6 also move. A gravity plate 7 is rotatably connected to the clamping plate 6. The connection between the gravity plate 7 and the clamping plate 6 is through a rotating shaft 15, and the connection between the rotating shaft 15 and the clamping plate 6 is lubricated, which allows the gravity plate 7 to rotate flexibly relative to the clamping plate 6.

[0029] The mounting bracket 1 has evenly distributed bearing strips 8 inside. The two ends of the bottom of the bearing strips 8 are respectively installed on the top of two opposite gravity plates 7. When the bearing strips 8 are subjected to gravity, the gravity plates 7 will adaptively rotate and adjust according to the gravity of the bearing strips 8 to maintain the relative stability of the bearing strips 8.

[0030] The top of the support bar 8 is used to hold the easy-open lid. As the transmission chain 5 moves continuously, the support bar 8 also moves along the movement trajectory of the chain, thereby conveying the easy-open lid to the designated position for subsequent packaging operations. In actual use, it can also be used for buffering. For example, when the supply speed of easy-open lids is fast but the packaging speed is slow, excess easy-open lids can be temporarily stored in the support bar 8, waiting for the packaging operation to be carried out.

[0031] In this invention, the transmission sprocket 2, the limiting sprocket 10, and the transmission chain 5 work together to enable the chain to rotate in an L-shape, effectively utilizing space and achieving a flexible conveying path. Furthermore, the gravity plate 7 and the clamping plate 6 are connected by a lubricated rotating shaft 15, allowing for adaptive adjustment based on the gravity of the carrying bar 8, maintaining its stability and ensuring smooth conveying. This enables both orderly conveying and buffering when supply and packaging speeds differ. Additionally, the top of the mounting bracket 1 can be extended, and changing the number of transmission sprockets 2 alters the chain length, thereby changing the storage capacity. This allows for flexible adjustment according to actual needs, making it highly adaptable.

[0032] Please see Figure 1 and 4 The mounting bracket 1 has evenly distributed ear plates 11 fixedly installed on its outer side. An adjusting shaft 12 is threaded onto the ear plate 11, and a mounting plate 13 is connected to the bottom end of the adjusting shaft 12.

[0033] In this utility model, the mounting bracket 1 needs to be installed in the easy-open lid packaging system in actual use. The position of the adjusting shaft 12 can be changed by the nut, thereby changing the position of the mounting bracket 1 from the mounting plate 13, and fine-tuning the installation height of the mounting bracket 1 to facilitate installation.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
