Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, specifically a new type of packaging bag tensile testing device. Background Technology

[0002] After the packaging bags arrive at the roasting workshop, they need to be randomly sampled and tested for tensile strength according to the system requirements. However, the roasting workshop does not have a dedicated packaging bag tensile strength testing device. During the test, a safety belt verification device needs to be borrowed from the overhaul workshop. Since the safety belt verification device is not a dedicated packaging bag tensile strength testing device, it is extremely inconvenient to operate and use. It also requires two people to cooperate to complete the operation, resulting in low testing efficiency. In addition, the overhaul workshop is far away from the roasting workshop, requiring the packaging bags to be transported back and forth, which wastes time and workers' physical strength. Utility Model Content

[0003] To address the problems mentioned above, this invention provides a novel packaging bag tensile testing device. The device uses a fixing component to secure the bottom of the packaging bag and an electric hoist to hook the top of the bag. As the electric hoist pulls the bag upwards, it simultaneously pulls down a tension gauge. With both forces equal and opposite, the reading on the tension gauge is the tensile strength of the packaging bag, thus completing the tensile test. The entire operation is simple and convenient, requiring only one person, thus improving testing efficiency. Furthermore, the device is installed inside the silo of the roasting workshop, eliminating the need for repeated handling of the packaging bags and facilitating daily sampling inspections of the bags.

[0004] This utility model provides a novel packaging bag tensile testing device, including a main frame, the bottom end of which is fixed to the ground of the silo, a tensile gauge is fixedly installed at the top end of the main frame, an electric hoist is provided at the bottom end of the tensile gauge, the hook of the electric hoist hooks the top of the packaging bag, and a fixing component is provided at the bottom of the main frame for fixing the bottom of the packaging bag.

[0005] Furthermore, a tension gauge display screen for displaying the tension count value is installed on the inner wall of the silo. The tension gauge display screen is electrically connected to the tension gauge. An electric hoist control button for controlling the lifting and lowering of the electric hoist is also installed on the inner wall of the silo. The electric hoist control button is electrically connected to the electric hoist.

[0006] Furthermore, the fixing component includes two fixing plates, which are fixedly connected to the bottom of the main frame. Each fixing plate has a through hole, and a pin is provided between the two fixing plates. The pin is inserted into the through hole, and the two fixing plates are located on both sides of the packaging bag, with the pin penetrating through the packaging bag.

[0007] Furthermore, both ends of the pin are provided with through holes, and the bottom of the main frame is provided with two threaded holes. The through holes and the threaded holes are set one-to-one. A limiting screw is inserted into the through hole, and one end of the limiting screw is threadedly connected to the threaded hole.

[0008] Furthermore, multiple reinforcing connecting columns are fixedly connected to one side of the main frame, with the end of the reinforcing connecting column away from the main frame fixedly connected to the inner wall of the silo.

[0009] Furthermore, the silo is equipped with guardrails that surround the main frame.

[0010] Furthermore, the guardrail is equipped with a guardrail gate, which is hinged to the guardrail, and a locking component is provided on the side of the guardrail gate away from the hinge.

[0011] Furthermore, the locking assembly includes a fixing sleeve fixed to the guardrail, the fixing sleeve being vertically arranged, a pin being vertically movable inside the fixing sleeve, a fixing block being fixedly connected to the side of the guardrail gate away from the hinge, a locking sleeve being fixedly connected to the fixing block, the locking sleeve being arranged opposite to the fixing sleeve, and the bottom end of the pin being movably inserted into the locking sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) When conducting a tensile test on a packaging bag, first use a fixing component to fix the bottom of the packaging bag, and then use the hook of an electric hoist to hook the top of the packaging bag. While the electric hoist pulls the packaging bag upward, it will pull the tensile gauge downward. The force of the electric hoist pulling the packaging bag upward and the force of pulling the tensile gauge downward are equal in magnitude and opposite in direction. Therefore, the value of the tensile gauge is the tensile value of the packaging bag, and the tensile test of the packaging bag can be completed. The whole operation is simple and convenient and can be completed by one person, which improves the efficiency of the test. Moreover, the device is installed in the silo of the roasting workshop, which avoids the operation of carrying the packaging bags back and forth, and facilitates the daily sampling inspection of the packaging bags in the workshop.

[0014] (2) When using the fixing components to fix the bottom of the packaging bag, place the packaging bag between two fixing plates, first insert the pin into one through hole, then pass the pin through the packaging bag, and then pass it out through another through hole. Thus, the packaging bag is fixed to the bottom of the main frame by the fixing plates and the pin. Then adjust the position of the through hole on the pin so that the through hole is aligned with the threaded hole. Then, pass the limiting screw through the through hole and thread it into the threaded hole. The limiting screw can limit the lateral movement of the pin, improve the stability of the pin, and thus prevent the packaging bag from falling out due to the lateral movement of the pin.

[0015] (3) The guardrail separates the test area from the workers, improving the safety of the workers. The guardrail is equipped with a guardrail door, which allows the workers to enter the test area and facilitate the replacement of packaging bags. When the guardrail door needs to be opened, pull the pin upward. When the pin moves upward and disengages from the locking sleeve, the guardrail door can be opened. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The present invention will be described in detail with specific embodiments.

[0024] When conducting a packaging bag tensile test, first use the fixing component 5 to fix the bottom of the packaging bag, then use the hook of the electric hoist 4 to hook the top of the packaging bag. While the electric hoist 4 lifts the packaging bag upwards, it will also pull the tensile gauge 3 downwards. The force of the electric hoist 4 lifting the packaging bag upwards and the force of the electric hoist 4 pulling the tensile gauge 3 downwards are equal in magnitude and opposite in direction. Therefore, the value of the tensile gauge 3 is the tensile value of the packaging bag, and the tensile test of the packaging bag can be completed. The whole operation is simple and convenient and can be completed by one person, which improves the efficiency of the test. Moreover, the device is installed in the silo of the roasting workshop, avoiding the operation of carrying the packaging bags back and forth, which facilitates the daily sampling inspection of the packaging bags in the workshop.

[0025] The inner wall of the silo 1 is equipped with a tension gauge display screen 30 for displaying the value of the tension gauge 3.

[0028] When using the fixing component 5 to fix the bottom of the packaging bag, place the packaging bag between the two fixing plates 50. First, insert the pin 52 into one through hole 51, then pass the pin 52 through the packaging bag, and then exit through the other through hole 51. Thus, the packaging bag is fixed to the bottom of the main frame 2 by the fixing plates 50 and the pin 52. Then, adjust the position of the through hole 53 on the pin 52 so that the through hole 53 is aligned with the threaded hole 55. Then, pass the limiting screw 54 through the through hole 53 and thread it into the threaded hole 55. The limiting screw 54 can limit the lateral movement of the pin 52, improve the stability of the pin 52, and thus prevent the packaging bag from falling out due to the lateral movement of the pin 52.

[0029] Multiple reinforcing connecting columns 6 are fixedly connected to one side of the main frame 2. The end of the reinforcing connecting column 6 away from the main frame 2 is fixedly connected to the inner wall of the silo 1.

[0030] A guardrail 7 is installed inside the silo 1, and the guardrail 7 surrounds the main frame 2. A guardrail door 70 is installed on the guardrail 7, and the guardrail door 70 is hinged to the guardrail 7 by a hinge 71. A locking component 72 is installed on the side of the guardrail door 70 away from the hinge 71. The locking component 72 includes a fixing sleeve 720 fixed to the guardrail 7. The fixing sleeve 720 is vertically arranged, and an L-shaped pin 721 is vertically movable through the fixing sleeve 720. A fixing block 722 is fixedly connected to the side of the guardrail door 70 away from the hinge 71. A locking sleeve 723 is fixedly connected to the fixing block 722.
