Description

Technical Field

[0001] The utility model relates to the technical field of ziplock bag production, in particular to an auxiliary sealing device for ziplock bag production. Background Art

[0002] Ziplock bags are hot-cut machine-made plastic bags that can be repeatedly sealed. The packaging process of ziplock bags is usually done manually. Workers take out the sealed bags from the silo, open them manually, put the items in, and then seal them tightly. This operation method requires a lot of manpower, has high labor intensity, and low production efficiency. The existing packaging equipment can only realize the sealing process in the entire workflow.

[0003] The announcement number (CN215794880U) is retrieved, which discloses an auxiliary sealing device for automated anti-static ziplock bag production, comprising: a workbench, wherein sliding holes are symmetrically opened on the top of the workbench; sliding rods, symmetrically slidably connected to the middle of the workbench, wherein the sliding rods are slidably connected to the sliding rods; an extrusion plate, fixedly mounted on the bottom of the four sliding rods; a moving device, fixedly mounted on the top of the extrusion plate; a fixed plate, fixedly mounted on the top of the four sliding rods; and an extrusion device, mounted on the bottom of the fixed plate.

[0004] When implementing this technical solution, at least the following defects still exist: although the utility model uses a suction cup to fix the ziplock bag, thereby ensuring the heat sealing efficiency of the ziplock bag, after the suction cup is pressed and adsorbed, the suction cup and the ziplock bag form a vacuum negative pressure, which requires the staff to manually remove it, which is too laborious and cumbersome, thus affecting the batch sealing operation, and urgently needs to be improved. Therefore, we propose an auxiliary sealing device for ziplock bag production. Utility Model Content

[0005] The utility model aims to provide an auxiliary sealing device for producing ziplock bags, which solves the problems raised in the background technology.

[0007] By adopting the above technical scheme, the convex block on the fixed block can push the fixed frame, and the fixed frame can drive the suction cup to adsorb and fix the placed ziplock bag, thereby facilitating the heat sealing operation of the ziplock bag. When the heat sealing is completed, the extrusion block on the fixed block can squeeze the foot pump, and the foot pump discharges the gas into the suction cup through the air pipe. After the suction cup is filled with air, the negative pressure disappears, thereby separating the suction cup from the adsorbed and fixed ziplock bag, thereby saving the trouble of the staff to remove them one by one, and further ensuring the batch heat sealing operation of the ziplock bag.

[0008] Optionally, the air outlet end of the foot pump is connected to an air pipe, and the other end of the air pipe is connected to the air inlet end of the suction cup.

[0009] By adopting the above technical solution, it is convenient to transmit gas through the setting of the air pipe.

[0010] Optionally, a spring is sleeved on the outer wall of the upper end of the fixing frame, and the other side of the spring is fixedly connected to the upper end of the supporting platform.

[0011] By adopting the above technical solution, it is convenient to arrange the spring so that the spring can drive the fixing plate to reset.

[0012] Optionally, the upper end of the air pipe is connected to a one-way valve, and the one-way valve is arranged on a side close to the suction cup.

[0013] By adopting the above technical solution, it is convenient to set a one-way valve, so as to ensure that gas can only enter but not exit, thereby ensuring the negative pressure effect of the suction cup.

[0014] Optionally, an extrusion block is fixedly installed on the other side of the fixed block, and the extrusion block corresponds to the foot pump.

[0015] By adopting the technical solution, it is convenient to arrange the extrusion block so that the extrusion block can squeeze and exhaust the foot pump.

[0016] Optionally, an upper end of one side of the fixing frame is movably arranged to penetrate one side of the supporting platform.

[0017] By adopting the above technical solution, the stability of the upward and downward movement of the fixing frame is ensured.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] The technical solution of the present application, through the arrangement of a support platform, a fixing frame, a suction cup, a servo motor, a fixing block, a protrusion, an extrusion block, a foot pump and a one-way valve, can enable the protrusion on the fixing block to push the fixing frame, and the fixing frame drives the suction cup to adsorb and fix the placed ziplock bag, thereby facilitating the heat sealing operation of the ziplock bag. When the heat sealing is completed, the extrusion block on the fixing block can also be used to squeeze the foot pump, and the foot pump discharges the gas into the suction cup through the air pipe. After the suction cup is filled with air, the negative pressure disappears, thereby separating the suction cup from the adsorbed and fixed ziplock bag, thereby saving the trouble of the staff removing them one by one, and further ensuring the batch heat sealing operation of the ziplock bag.
