Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing, in particular to an air tightness detection device for packaging bags. Background Art

[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. In order to ensure the subsequent sealing effect of the packaging bags, it is generally necessary to conduct airtightness testing on them during production to ensure the sealing effect of the packaging bags. When testing the airtightness of the packaging bags, it is necessary to use an airtightness testing device to test the sealing effect of the packaging bags.

[0003] When testing the air tightness of packaging bags, an air tightness testing device is needed. Among them, the "A device for testing air tightness of packaging bags with interlayer protective air" disclosed in the announcement number "CN204630698U" has solved the various disadvantages of being unable to apply corresponding different pressures to packaging bags of different specifications for air tightness testing.

[0004] However, there are still many defects in the actual use of airtightness detection devices with similar structures, such as: the use of water source testing in the prior art is prone to cause water waste, and the use of water source to test the sealing of packaging bags requires wiping the water source and drying operations, which increases the work flow of the packaging bag sealing test and reduces the energy-saving and environmental protection effect of the device. At the same time, when using the device, the operator needs to use external equipment to collect the packaging bags, which increases the workload of the operator. Therefore, it is necessary to design an airtightness detection device for packaging bags. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an air tightness detection device for packaging bags to solve the above problems.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a packaging bag air tightness detection device, comprising a box body, a fixed frame is fixedly installed on one side of the top of the box body, a movable seat is movably installed inside the fixed frame, and a driving mechanism for detecting the air tightness of the packaging bag is fixedly installed on one side of the movable seat, and an auxiliary collection mechanism for collecting the packaging bags is fixedly installed on one side of the box body;

[0007] The driving mechanism comprises a mounting frame, an electric rod is fixedly mounted on the top of the mounting frame, a pressure sensor is fixedly mounted on the output end of the electric rod, a shell for resisting the packaging bag is fixedly mounted on the bottom end of the pressure sensor, and an alarm is fixedly mounted on one side of the top of the mounting frame;

[0008] The auxiliary collection mechanism comprises a base, and slots are equidistantly arranged on one side of the base.

[0009] Preferably, two sets of supporting feet are fixedly installed on one side of the bottom of the box, and rubber pads are fixedly installed on the bottom of the supporting feet. The supporting feet can provide installation positions for the rubber pads, and the rubber pads can increase the contact area between the supporting feet and the ground, ensuring the stability of the box and preventing the box from tipping over due to force.

[0010] Preferably, a plurality of groups of second solenoid valve tubes are equidistantly installed on the top of the movable seat, a first solenoid valve tube is fixedly installed on one side of the second solenoid valve tube, and a nozzle extending to the inside of the movable seat is fixedly installed on the bottom of the second solenoid valve tube. When the second solenoid valve tube is powered on and turned on, air can be input into the nozzle by external equipment, and then the air can be transported to the inside of the packaging bag through the nozzle for testing. After the testing is completed, the second solenoid valve tube can be powered on and turned on to allow external equipment to absorb the air inside the packaging bag, thereby realizing the function of testing the air tightness of the packaging bag.

[0011] Preferably, a docking tube is fixedly installed on the other side of the base, a collection box used in conjunction with the base is fixedly installed on the back of the box body, a mesh plate is embedded in one side of the collection box, and a box door is movably installed on one side of the collection box through a hinge.

[0012] Preferably, two sets of electric push rods are fixedly installed on the other side of the bottom of the box, and the output ends of the electric push rods are fixedly connected to the outer side of the moving seat. The electric push rods are powered on to drive the moving seat to move vertically, and the moving seat that moves vertically can be used in conjunction with the base to hold and fix the packaging bag, which is convenient for subsequent inflation test operations on the packaging bag.

[0013] Preferably, a rubber seat corresponding to the shell is fixedly installed at the center of the top of the box, and a plurality of placement grooves are provided inside the rubber seat. The rubber seat and the placement grooves are used together to facilitate the placement of the packaging bag, thereby preventing the packaging bag from moving by itself due to external influences.

[0014] Beneficial Effects

[0015] The utility model provides a packaging bag air tightness detection device. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The pressure sensor is driven to move vertically by energizing the electric rod. The pressure sensor that moves vertically can drive the shell to move to one side of the packaging bag for resistance, and the pressure data of the packaging bag can be monitored in real time by energizing the pressure sensor. The air tightness of the packaging bag can be monitored by the pressure sensor to determine whether the packaging bag is leaking. When the air tightness of the packaging bag does not meet the specified processing requirements, the alarm is controlled by the pressure sensor to generate sound and light to warn the operator, so that the operator can collect the packaging bags that do not meet the air tightness standards. The function of improving the efficiency of the air tightness test of the packaging bag by using multiple sets of independently operated pressure sensors in conjunction with the electric rod avoids the problem of water waste caused by the water source test in the existing device, and increases the energy-saving and environmental protection effect of the device.

[0017] 2. After docking with external equipment through the docking tube, the air sucked by the external equipment can be transported to the inside of the base, and then the air can be transported to the top of the box through the slots, so that the packaging bags after the test are transported by wind, so that the packaging bags enter the collection box, and then the porous structure of the mesh plate can be used to discharge the air inside the collection box and collect and store the packaging bags, realizing the function of auxiliary collection of packaging bags, avoiding the problem of operators collecting packaging bags with the help of external equipment, and reducing the workload of operators.
