[0029] The device 10 for improving the efficiency of folding and sewing includes: the device 10 for improving the efficiency of folding and sewing is additionally provided with a gear adjustment switch 3, the gear adjustment switch 3 changes the conveying direction of the mesh belt machine 1 by controlling the mesh belt machine drive device 2, and is used to control the closing, forward rotation and reverse rotation of the mesh belt machine drive device 2; the device 10 for improving the efficiency of folding and sewing also includes a guide device 4 and a protective device 5, the guide device 4 is used to prevent the conveyor belt 13 from being stuck in the gap between the sprocket parts 11 when the mesh belt machine drive device 2 is reversed, causing damage to the conveyor belt 13, and the protective device 5 is used to prevent the bagged material from falling abnormally from the conveyor belt 13 when the mesh belt machine 1 is reversed.

[0030] In this embodiment, the gear adjustment switch 3 focuses on changing the conveying direction to improve work efficiency. The gear adjustment switch 3 is divided into three gear modes to meet the needs of different working scenarios.

[0031] Specifically, the gear adjustment switch 3 includes a forward gear 31. When the gear adjustment switch 3 is adjusted to the forward gear 31, it is used to drive the mesh belt conveyor 1 to transport the material from the tail sprocket part 112 to the head sprocket part 111. The forward gear 31 is used for the normal filling operation process. More specifically, there is a bagging port (not shown) above the tail of the mesh belt conveyor 1. After the bag is put on, it is transported from the tail of the mesh belt conveyor 1 to the head of the mesh belt conveyor 1.

[0032] Specifically, the gear adjustment switch 3 includes a reverse gear 32. When the gear adjustment switch 3 is adjusted to the reverse gear 32, it is used to drive the mesh belt conveyor 1 to convey the material from the head sprocket part 111 to the tail sprocket part 112.

[0033] Specifically, the gear adjustment switch 3 includes a stop gear 33 for stopping the conveying process of the material on the mesh belt conveyor 1. The stop gear 33 is used when the production operation needs to be suspended.

[0034] Specifically, if Figure 1and Figure 4 As shown, the setting form of the gear adjustment switch 3 is preferably a rotary type, and different gears are controlled by the knob to meet the needs of different production scenarios. The gear adjustment switch 3 is set to a rotary type mainly for convenience. In actual use, it can be adjusted to a toggle switch, electronic switch, etc. for replacement according to objective conditions.

[0035] In this embodiment, the mesh belt conveyor driving device 2 is provided on the mesh belt conveyor 1 , and preferably adopts a motor, and cooperates with the gear adjustment switch 3 to switch the operation mode of the mesh belt conveyor 1 .

[0036] In this embodiment, in order to further improve the working efficiency, the device 10 for improving the efficiency of folding and sewing packages further includes a guide device 4 provided at one end of the head sprocket portion 111, such as Figure 2 and Figure 3 As shown, due to the gap between the sprocket part 11 and the main steel structure of the mesh belt machine 1, when the mesh belt machine 1 reverses, the conveyor belt 13 is prone to fold and fall into the gap between the main steel structure of the mesh belt machine 1 and the sprocket part 11, thereby getting stuck and causing a malfunction. The setting of the guide device 4 is used to guide the conveying direction of the conveyor belt 13, prevent the conveyor belt 13 from getting stuck, and cause a tooth jumping malfunction, thereby improving the operating efficiency of the mesh belt machine 1.

[0037] Specifically, the guide device 4 is preferably installed to extend along the head sprocket portion 111 and is bent to match the curvature of the head sprocket portion 111 to achieve a better guiding effect on the conveyor belt 13.

[0038] Specifically, by Figures 1 to 3 As shown, the guide device 4 is preferably selected as a round steel extending from the main steel structure of the head sprocket part 111. In order to ensure the use effect, two round steels are provided, and at the same time, they are appropriately bent with reference to the curvature of the sprocket part 11. The round steel is not only easy to obtain, but also has good stability as the guide device 4. When used in actual production, common building materials such as steel bars or round wood can be used as replacements according to objective conditions.

[0039] In this embodiment, in order to further improve work efficiency, the device 10 for improving the efficiency of folding and sewing bags also includes a protective device 5 provided on the tail sprocket part 112, which is used to prevent materials from falling from the tail sprocket part 112. When the mesh belt machine 1 reverses, the material is transported from the head sprocket part 111 to the tail sprocket part 112, and the protective device 5 receives the material at the tail sprocket part 112 to prevent the material from falling from the tail sprocket part 112 and causing the work process to be stuck.

[0040] Specifically, in order to improve the practicality of the protection device 5 , the shape of the protection device 5 is set to be a frame type, including side frames 51 and a top frame 52 , and the side frames 51 are arranged on both sides of the top frame 52 .

[0041] Specifically, in order to improve the stability of the protective device 5, a reinforcement 53 is provided inside the side frame 51 and the top frame 52. In this embodiment, the reinforcement 53 is specifically set to round steel. Filling the side frame 51 and the top frame 52 with round steel as a preferred embodiment has the characteristics of strong stability, ensuring the working efficiency of the reverse operation of the mesh belt machine 1. When used in specific work, other common building materials can be used to replace the round steel, such as steel bars, round wood, etc.

[0042] In this embodiment, the device 10 for improving the efficiency of folding and sewing is additionally provided with a frequency converter 6, which is arranged on the filling box 100. The frequency converter 6 is used to control the power of the mesh belt machine drive device 2 and adjust the speed of the mesh belt machine 1.
