Sealing Structure of Air-Pocket Film Machine

Abstract

A sealing structure of an air-pocket bag machine includes at least one heating plate, a sealing roller that is rotatably mounted to and positioned against the heating plate for conducting a heating and pressing operation on and thus sealing at least one air-pocket bag through a heating operation of the heating plate, and at least one driving roller that is coaxially and rotatably coupled to the sealing roller for driving and advancing the air-pocket bag. With such an arrangement, when the air-pocket bag machine is activated, the air-pocket bag is driven by being in contact engagement with the driving roller and thus is moved to fast, stably, and continuously pass under the sealing roller. Due to the sealing roller and the driving roller being rotatably coupled in a coaxial manner, the advancing speed of the air-pocket bag is consistent with the rotational speed of the sealing roller.

I claim: 
     
         1 . A sealing structure of an air-pocket bag machine, comprising:
 at least one heating plate;   a sealing roller that is rotatably mounted to and positioned against the heating plate for conducting a heating and pressing operation on and thus sealing at least one air-pocket bag through a heating operation of the heating plate; and   at least one driving roller that is coaxially and rotatably coupled to the sealing roller for driving and advancing the air-pocket bag.   
     
     
         2 . The sealing structure of the air-pocket bag machine according to  claim 1 , wherein the sealing roller comprises a heat conduction board in contact engagement with the heating plate. 
     
     
         3 . The sealing structure of the air-pocket bag machine according to  claim 2  further comprising a base that houses the heating plate and the heat conduction board therein. 
     
     
         4 . The sealing structure of the air-pocket bag machine according to  claim 3 , wherein the base comprises, formed therein, a receiving space for receiving the heating plate and the heat conduction board and at least one isolation space at one side of the receiving space. 
     
     
         5 . The sealing structure of the air-pocket bag machine according to  claim 3 , wherein the heating plate, the heat conduction board, and the base each comprise at least one positioning hole formed therein. 
     
     
         6 . The sealing structure of the air-pocket bag machine according to  claim 5 , wherein the positioning hole receives a fastener to extend therethrough. 
     
     
         7 . The sealing structure of the air-pocket bag machine according to  claim 1 , wherein the sealing roller has an outer circumference forming a contact surface. 
     
     
         8 . The sealing structure of the air-pocket bag machine according to  claim 1 , wherein the driving roller is made of a rubber material. 
     
     
         9 . The sealing structure of the air-pocket bag machine according to  claim 1 , wherein the heating plate and the sealing roller are made of metallic materials.
