Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt technology, and in particular relates to a tensioned conveyor belt for a bag making machine. Background Technology

[0002] A conveyor belt is a continuous circulating transmission component consisting of a drive unit, tensioning device, and load-bearing device. It is used to automatically transfer materials or products between different workstations. It is widely used in industrial automated production lines and features high efficiency, stability, and continuous conveying. It can operate horizontally, inclined, or in combination to adapt to various production environments. In bag making machines, the conveyor belt is mainly used to transport pre-formed bags. Its function is to smoothly and orderly transport bags that have completed heat sealing, cutting, and other processes to the next workstation, such as the stacking or boxing area. The conveyor belt ensures the continuity of the bag making process, improves production efficiency, and at the same time avoids wrinkles or damage to the bags during transportation, ensuring the product's appearance quality. By cooperating with control systems such as photoelectric sensors and PLCs, it can also realize functions such as counting and positioning. It is an indispensable key component for automated bag making.

[0003] When using a conveyor belt on a bag-making machine, the tension of the conveyor belt can be adjusted by moving the tension rollers horizontally back and forth to adapt to the conveying needs of different products. For combined conveyor belts, tension rollers are provided on both the upper and lower layers, and the two ends of each layer's tension rollers need to be adjusted independently. Therefore, a total of four drive devices are required to control the synchronous horizontal movement of the upper and lower layers of tension rollers to ensure stable operation. However, configuring four drive devices significantly increases the system's energy consumption. Although the multi-drive mode ensures the uniformity and stability of tension, the superimposed operation of the drive devices leads to increased power consumption and increased equipment control complexity. This not only increases production costs but also weakens the energy-saving performance of the bag-making machine's tensioning mechanism, affecting the overall energy efficiency level and becoming one of the factors restricting the green development of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a tension conveyor belt for a bag making machine. Through the cooperation of components such as the slider mechanism, sliding guide rail, T-shaped frame and electric push rod, the first tension roller and the second tension roller can be moved horizontally back and forth at both ends by only two electric push rods, thus solving the energy consumption problem of existing tension conveyor belts for bag making machines.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a tensioning conveyor belt for a bag-making machine, comprising a bag-making machine body, a conveyor belt body, a first tensioning roller, and a second tensioning roller. The conveyor belt body is fixedly connected to the bag-making machine body. A first tensioning roller is slidably connected to the bag-making machine body above the conveyor belt body. A second tensioning roller is slidably connected to the bag-making machine body below the first tensioning roller. Sliding mechanisms are rotatably connected to both ends of the first tensioning roller and both ends of the second tensioning roller. Four sliding guide rails are symmetrically fixedly connected to the bag-making machine body. The sliding mechanisms are slidably connected to the sliding guide rails. A T-shaped frame is slidably connected to the sliding mechanism between two of the sliding guide rails. An electric push rod is fixedly connected to the bag-making machine body on one side of the T-shaped frame. The moving end of the electric push rod is fixedly connected to the T-shaped frame.

[0007] By adopting the above technical solution, the ends of the first tensioning roller and the second tensioning roller are respectively placed inside the slider mechanism. The moving end of the electric push rod extends or shortens, driving the T-shaped frame to move horizontally back and forth, driving the upper and lower slider mechanisms to move horizontally back and forth simultaneously, and driving the first tensioning roller and the second tensioning roller to move horizontally back and forth. Depending on the type of product, only two electric push rods are needed to adjust the tension of the first tensioning roller and the second tensioning roller, thus improving the energy-saving effect of the tensioned conveyor belt.

[0008] Furthermore, the end of the sliding guide rail away from the main body of the bag making machine has an open design.

[0009] By adopting the above technical solution, the moving end of the electric push rod extends, moving the slider mechanism out of the sliding guide rail, allowing for the inspection or replacement of the first tensioning roller, the second tensioning roller, and the slider mechanism.

[0010] Furthermore, the top and bottom of the T-shaped frame are provided with displacement grooves, and the end of the slider mechanism near the T-shaped frame is fixedly connected to a displacement block that is slidably connected to the displacement groove.

[0011] By adopting the above technical solution, the upper or lower slider mechanism can be moved, and the displacement block can slide inside the displacement groove. The longitudinal misalignment of the centers of the first tensioning roller and the second tensioning roller can adjust the tension of the first tensioning roller and the second tensioning roller respectively. The coaxiality of the centers of the first tensioning roller and the second tensioning roller can maintain the same tension.

[0012] Furthermore, a second threaded rod is symmetrically rotatably connected to the T-shaped frame. The second threaded rod passes through the interior of the displacement groove, and the threaded surface of the second threaded rod engages with the interior of the displacement block.

[0013] By adopting the above technical solution, rotating the handle at one end of the second threaded rod causes the displacement block to slide along the inside of the displacement groove, thereby adjusting the position of the slider mechanism inside the sliding guide rail.

[0014] Furthermore, the slider mechanism includes a first slider assembly rotatably connected to both ends of the first tension roller and both ends of the second tension roller. A fixed mounting bracket is fixedly connected to the first slider assembly. A second slider assembly located above the first slider assembly is slidably connected inside the fixed mounting bracket. The second slider assembly is rotatably connected to both ends of the first tension roller and both ends of the second tension roller.

[0015] By adopting the above technical solution, the first tension roller or the second tension roller enters the interior of the fixed mounting frame through the notch on one side of the fixed mounting frame. The first tension roller and the second tension roller enter the groove on the upper surface of the first slider assembly. The second slider assembly moves downward along the interior of the fixed mounting frame to block the notch of the fixed mounting frame, preventing the first tension roller and the second tension roller from moving out of the interior of the fixed mounting frame. When the first tension roller or the second tension roller needs to be inspected or maintained, the second slider assembly moves upward, and the first tension roller or the second tension roller moves out from the notch of the fixed mounting frame.

[0016] Furthermore, a piston mounting shell is fixedly connected to the top of the fixed mounting bracket, the interior of the piston mounting shell is in communication with the interior of the fixed mounting bracket, a piston rod is slidably connected to the interior of the piston mounting shell and fixedly connected to the upper surface of the second slider assembly, and a first threaded rod is rotatably connected to the top of the piston mounting shell, the first threaded rod passes through the interior of the piston mounting shell, and the threaded surface of the first threaded rod engages with the interior of the piston rod.

[0017] By adopting the above technical solution, rotating the first threaded rod controls the piston rod to enter or exit the piston mounting housing. When the piston rod retracts into the piston mounting housing, the second slider assembly moves upward, the piston rod moves out of the piston mounting housing, and the second slider assembly moves downward. The position of the second slider assembly can be manually adjusted.

[0018] Furthermore, three protective rollers are equidistantly rotatably connected to the upper surface of the first slider assembly and the lower surface of the second slider assembly, and both ends of the first tension roller and both ends of the second tension roller are in contact with the surface of the protective rollers.

[0019] By adopting the above technical solution, the protective roller reduces the friction between the two ends of the first tension roller and the second tension roller and the grooves of the first slider assembly and the second slider assembly, thereby reducing wear.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, by installing a slider mechanism, a sliding guide rail, a T-shaped frame, and an electric push rod, places the two ends of the first tensioning roller and the second tensioning roller into the slider mechanism respectively. The moving end of the electric push rod extends or retracts, driving the T-shaped frame to move horizontally back and forth, driving the upper and lower slider mechanisms to move horizontally back and forth simultaneously, and driving the first tensioning roller and the second tensioning roller to move horizontally back and forth. Depending on the type of product, only two electric push rods are needed to adjust the tension of the first tensioning roller and the second tensioning roller, thus improving the energy-saving effect of the tensioned conveyor belt.

[0034] The top and bottom of the T-shaped frame 7 are provided with displacement grooves 9, and the end of the slider mechanism 5 near the T-shaped frame 7 is fixedly connected to a displacement block 10 that is slidably connected to the displacement grooves 9.

The second slider assembly 53 moves downward, allowing for manual adjustment of the second slider assembly. Position of the block assembly 53: The second slider assembly 53 moves downward along the inside of the fixed mounting bracket 52, blocking the notch of the fixed mounting bracket 52 to prevent the ends of the first tension roller 3 and the second tension roller 4 from moving out of the fixed mounting bracket 52. When the first tension roller 3 or the second tension roller 4 needs to be inspected or maintained, the second slider assembly 53 moves upward, and the first tension roller 3 or the second tension roller 4 moves out of the notch of the fixed mounting bracket 52. The protective roller 57 reduces the friction between the ends of the first tension roller 3 and the second tension roller 4 and the grooves of the first slider assembly 51 and the second slider assembly 53, thereby reducing wear.
