Description

Technical Field

[0001] This utility model relates to the field of plastic packaging bag technology, and in particular to a tensile testing mechanism for plastic packaging bags. Background Technology

[0002] Plastic packaging bags are packaging bags made of plastic as raw materials. As the outer packaging of products, they can protect goods and prevent them from being damaged during transportation and sales. They are now widely used in daily life and industrial production. In the processing of plastic packaging bags, tensile testing is a relatively important step. Through tensile testing, the load-bearing capacity of the plastic packaging bag can be calculated, so that the plastic packaging bag can meet the actual use requirements.

[0003] Utility model patent CN216012973U discloses a tensile testing device for packaging material production, including a test box with a test structure installed on it. A first screw is rotatably connected to the test box via bearings. Two fixing plates are threaded onto the first screw. Two sliding rods are fixedly connected to the fixing plates in a parallel and symmetrical relationship. A fixing sleeve is fixedly connected to each sliding rod. A second screw is rotatably connected to the fixing sleeve via bearings. Two threaded blocks are threaded onto the second screw, and clamping blocks are fixedly connected to the two threaded blocks. This device can better distinguish which of two sets of plastic packaging bags has better flexibility.

[0004] Existing tensile testing devices have the following drawbacks: they lack a structure that utilizes a conveyor belt and weights to test the tensile strength of plastic packaging bags, resulting in limited practicality. Therefore, we propose a tensile testing mechanism for plastic packaging bags. Summary of the Invention

[0005] The main objective of this invention is to provide a tensile testing mechanism for plastic packaging bags, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tensile testing mechanism for plastic packaging bags includes a base. A first support column and a second support column are respectively installed at both ends of the top of the base. A plastic packaging bag is placed at the lower end between the first support column and the second support column. A horizontal plate is installed at the top of the first and second support columns. Vertical mounting plates are installed on both sides of the top of the horizontal plate. A reduction motor is mounted on one side of the vertical mounting plate via a mounting base. A drive roller is installed at the output end of the reduction motor. A fixed pulley is installed at one end between the vertical mounting plates. A weight is installed at the upper end between the first and second support columns. A conveyor belt connects the weight and the drive roller.

[0008] Furthermore, hooks are provided at the upper inner sides of both the No. 1 and No. 2 support columns, and both ends of the top of the plastic packaging bag are connected to the hooks. A fixed pulley is provided on the top of the horizontal plate on one side of the vertical mounting plate, and a reserved opening is provided on the horizontal plate on one side of the fixed pulley.

[0009] Furthermore, a motor forward and reverse control controller is provided at the top of the horizontal plate on one side of the reduction motor.

[0010] Furthermore, the current output terminal of the motor forward and reverse rotation controller is electrically connected to the current input terminal of the geared motor via a wire.

[0011] Furthermore, the lower end of the weight is located inside the plastic packaging bag.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The system consists of a geared motor, drive roller, fixed pulley, weights, and a conveyor belt. The geared motor drives the weights up and down via the drive roller and conveyor belt. The fixed pulley guides the movement of the conveyor belt from the top, allowing it to move smoothly. Once the weights have fallen completely into the bottom of the plastic bag, the geared motor is stopped. The plastic bag can then support the weights, allowing for a test of the tensile strength the bag can withstand. This enables the calculation of the bag's load-bearing capacity, determining whether the bag meets actual usage requirements. This method, using a conveyor belt and weights, achieves the goal of tensile strength testing of plastic bags. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a tensile testing mechanism for plastic packaging bags includes a base 1. A first support column 2 and a second support column 3 are respectively installed at the two ends of the top of the base 1. A plastic packaging bag 4 is installed at the lower end between the first support column 2 and the second support column 3. A horizontal plate 5 is installed at the top of the first support column 2 and the second support column 3. Vertical mounting plates 6 are installed on both sides of the top of the horizontal plate 5. A reduction motor 7 is mounted on one side of the vertical mounting plate 6 via a mounting base. A drive roller 8 is installed at the output end of the reduction motor 7. A fixed pulley 9 is installed at one end between the vertical mounting plates 6. A weight 10 is installed at the upper end between the first support column 2 and the second support column 3. A conveyor belt 11 connects the weight 10 and the drive roller 8.

[0021] The upper inner sides of the first support column 2 and the second support column 3 are each provided with a hook 12. Both ends of the top of the plastic packaging bag 4 are connected to the hook 12. The top of the horizontal plate 5 is provided with a fixed pulley 9 on one side of the vertical mounting plate 6. A reserved opening 14 is provided on the horizontal plate 5 on one side of the fixed pulley 9.

[0022] In this embodiment, as shown Figure 1-4 As shown, the hook 12 can limit the plastic packaging bag 4 so that the plastic packaging bag 4 can carry the weight 10, while the fixed pulley 9 can transition the movement of the conveyor belt 11 so that the conveyor belt 11 can move smoothly, and the reserved opening 14 makes it easy for the conveyor belt 11 to pass through the cross plate 5.

[0023] The top of the horizontal plate 5 is located on one side of the reduction motor 7 and is equipped with a motor forward and reverse control controller 13.

[0024] The current output terminal of the motor forward and reverse controller 13 is electrically connected to the current input terminal of the geared motor 7 via a wire.

[0025] In this embodiment, as shown Figure 1 , 2 As shown, the motor forward and reverse controller 13 can control the rotation direction of the geared motor 7.

[0026] The lower end of the weight 10 is located inside the plastic packaging bag 4.

[0027] In this embodiment, as shown Figure 1 , 2 As shown, the plastic packaging bag 4 can support the weight 10.

[0028] It should be noted that this utility model is a tensile testing mechanism for plastic packaging bags. During operation, the operator connects the top two ends of the plastic packaging bag 4 to the hooks 12, ensuring the bag 4 is securely positioned between the hooks 12 and the second support column 3. Furthermore, the reduction motor 7 drives the drive roller 8 to rotate, which in turn moves the weight 10 up and down via the conveyor belt 11. The fixed pulley 9 guides the movement of the conveyor belt 11 at its top, ensuring smooth movement. The motor forward and reverse rotation controller 13 (a product of Guangzhou Keshen Electronic Technology Co., Ltd.) controls the forward and reverse rotation of the reduction motor 7. The main functions of the motor forward and reverse rotation controller 13 include start and stop control, speed adjustment, and other functions. The motor forward and reverse controller 13 can receive operation commands and control the state of the geared motor 7 according to the commands. When the motor forward and reverse controller 13 receives a forward rotation command, it will drive the geared motor 7 to run in the forward direction. When it receives a reverse rotation command, it will drive the geared motor 7 to run in the reverse direction, which can drive the weight 10 to move up and down. Furthermore, when the weight 10 moves down and falls completely into the inner bottom of the plastic packaging bag 4, the operation of the geared motor 7 is stopped. The plastic packaging bag 4 can then bear the weight 10. The tensile force that the plastic packaging bag 4 can withstand can be tested by using the weight 10, and the load-bearing capacity of the plastic packaging bag 4 can be calculated to determine whether the plastic packaging bag 4 meets the actual use requirements.
