Description

Technical Field

[0001] This utility model relates to the field of bag traction technology, specifically a multi-row soft bag traction mechanism. Background Technology

[0002] Currently, most flexible bag packaging machines on the market are single-row machines, using a single-power traction system for bag pulling. This results in low equipment capacity, unstable film pulling, inconsistent speeds on both sides of multi-row film pulling that cannot be adjusted, and an inability to switch between multiple flexible bag packaging specifications. This is especially true for small-sized flexible bags, which in the industry typically refer to bags with a width of 100-150mm. Small-sized flexible bags require a high degree of synchronization between the two sides during transport. Furthermore, due to their bag shape, small-sized flexible bags do not require a large overall layout space, making the layout and synchronization of existing flexible bag traction machines incompatible. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-row soft bag traction mechanism to solve the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] A multi-row soft bag traction mechanism includes a transmission device, a fixed plate, a telescopic device, and a synchronous transmission device. The transmission device is slidably connected to the fixed plate, the telescopic device is adjustablely mounted on the fixed plate, and the telescopic end of the telescopic device is connected to the transmission device. The synchronous transmission device is connected to the transmission device.

[0006] The transmission device includes a drive motor, a slider plate, a guide rail, and a transmission shaft. The drive motor is fixed to the slider plate, which is slidably connected to the guide rail. One end of the transmission shaft passes through the slider plate and connects to the output end of the drive motor, while the other end connects to the synchronous transmission device.

[0007] The telescopic device is equipped with an adjustment groove, which is adjustablely connected to the fixed plate via bolts.

[0008] The transmission and telescopic devices are arranged in pairs, with each pair of telescopic devices on their respective transmission devices positioned diagonally opposite to each other. For small-sized soft bags, the synchronization rate of the synchronous traction belt can be ensured by adjusting the output power of the drive motors on both sides of each transmission device in advance, making the film pulling more uniform and stable. At the same time, the arrangement of each pair of telescopic devices on their respective transmission devices optimizes the layout. While not affecting the transmission of small-sized soft bags, the layout is more compact and does not occupy too much space. Furthermore, several sets of transmission and telescopic devices can be added according to actual needs to cope with the synchronous traction of different types of small-sized soft bags.

[0009] Preferably, the synchronous transmission device includes a synchronous limiting plate, a synchronous wheel, a synchronous traction belt, and a follower column. The synchronous wheel is rotatably connected to the upper and lower sides of the synchronous limiting plate. The synchronous traction belt is rotatably connected to the synchronous wheel. One end of the follower column is fixed to the synchronous limiting plate, and the other end is fixed to the slider plate. A transmission shaft passes through the follower column, and the other end of the transmission shaft is connected to the synchronous wheel.

[0011] Preferably, the fixing plate is provided with fixing holes and movable grooves, the fixing holes and the adjusting grooves are positioned correspondingly, and the movable grooves are adapted to the shape of the follower column.

[0012] Preferably, the telescopic device is a cylinder assembly.

[0013] Compared to existing technologies, this utility model discloses a multi-row soft bag traction mechanism, including a transmission device, a fixing plate, a telescopic device, and a synchronous transmission device. These four components work together to achieve their functions. For small-sized soft bags, the output power of the drive motors on both sides of each transmission device can be adjusted in advance to ensure the synchronization rate of the synchronous traction belt, making the film pulling more uniform and stable. At the same time, the telescopic devices of each group are distributed in pairs on their respective transmission devices at a diagonal angle, which optimizes the layout. While not affecting the transmission of small-sized soft bags, the layout is more compact and does not occupy too much space. Furthermore, several sets of transmission devices and telescopic devices can be added according to actual needs to cope with the synchronous traction of different types of small-sized soft bags.

[0018] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A multi-row soft bag traction mechanism includes a transmission device 1, a fixed plate 2, a telescopic device 3, and a synchronous transmission device 4. The transmission device 1 is slidably connected to the fixed plate 2. The telescopic device 3 is adjustablely mounted on the fixed plate 2, and its telescopic end is connected to the transmission device 1. The synchronous transmission device 4 is connected to the transmission device 1. The transmission device 1 includes a drive motor 11, a slider plate 12, a guide rail 13, and a transmission shaft 14. The drive motor 11 is fixed to the slider plate 12, and the slider plate 12 is slidably connected to the guide rail 13. One end of the transmission shaft 14 passes through the slider plate 12 and connects to the output end of the drive motor 11, while the other end connects to the synchronous transmission device 4. The telescopic device 3 is provided with an adjustment groove 31, which is adjustablely connected to the fixing plate 2 by bolts. The transmission device 1 and the telescopic device 3 are arranged in pairs, and the telescopic devices 3 in each group are distributed in pairs on their respective transmission devices 1 in a left-right diagonal position. Currently, three groups are set in this scheme. If the production capacity needs to be increased, several more groups can be added to cope with the synchronous traction work of different types of small-sized soft bags. All three groups operate simultaneously.

[0020] The synchronous transmission device 4 includes a synchronous limiting plate 41, a synchronous wheel 42, a synchronous traction belt 43, and a follower column 44. The synchronous wheel 42 is rotatably connected to the upper and lower sides of the synchronous limiting plate 41. The synchronous traction belt 43 is rotatably connected to the synchronous wheel 42. One end of the follower column 44 is fixed to the synchronous limiting plate 41, and the other end is fixed to the slider plate 12. A transmission shaft 14 passes through the follower column 44, and the other end of the transmission shaft 14 is connected to the synchronous wheel 42. The telescopic device 3 has a telescopic end connected to the slider plate 12. The fixed plate 2 has a fixed hole 21 and a movable groove 22. The fixed hole 21 corresponds to the position of the adjustment groove 31, and the movable groove 22 is adapted to the shape of the follower column 44. The telescopic device 3 is a cylinder assembly.

[0021] Before work begins, the relative positions of the fixing hole 21 and the adjusting groove 31 are adjusted according to the thickness of the small-sized soft bag. After adjustment, bolts are used to connect and position the telescopic device 3 on the fixing plate 2. When work begins, the telescopic end of the telescopic device 3 moves forward, driving the slider plate 12 to move on the guide rail 13. After each group of telescopic devices 3 moves its respective transmission device 1 into place, the two synchronous traction belts 43 clamp the modules of small-sized soft bags coming from the upper production line. The drive motor 11 drives the transmission shaft 14 to rotate, driving the synchronous wheel 42 to rotate. At the same time, the synchronous traction belt 43 also rotates, driving the film group of small-sized soft bags to move downward continuously. When it ends, the drive motor 11 stops rotating and the telescopic end of the telescopic device 3 retracts. It is worth noting that the transmission speed on the left and right sides is different when different types of small-sized soft bags are transported together with synchronous traction belts 43 with different friction coefficients. Therefore, during the early debugging process, the drive motor 11 of each group should be adjusted to the optimal state to ensure that the transmission speed on both sides is relatively balanced.

[0022] Example 2

[0023] Without changing the above technical features, the synchronous traction belt 43 can also be provided with several negative pressure adsorption holes, and a negative pressure adsorption device is provided on the inner side, so that an additional adsorption and correction action is added during the traction and transmission of small-sized soft bags.
