In this embodiment, the upper strip 40 and the lower strip 41 are both set to be hidden, when the upper plate 6 on one side of the body is extruded into the corresponding travel of the upper slide 60, which means that the plastic film has entered the suction port 2 at this time, the hidden heat seal 4 will not generate heat effect on the plastic film, when the upper plate 6 enters the upper slide 60 and cannot move any more, one end of the upper plate 6 in the upper slide 60 will contact with the upper strip 40, because the upper strip 40 will generate heat, the upper strip 40 is connected with a section of heat insulation block 42, i.e. the upper plate 6 is in frictional contact with the heat insulation block 42, in the travel of the upper portion 10 near the lower portion 11, in this embodiment, the upper plate 6 is connected with the corresponding upper slide 61 by means of hinging, and the connection portion is provided with a torsion spring, so that the open end of the upper plate 6 will swing up due to friction effect, and the rotation center of the upper plate 6 will not generate heat effect on the plastic film, and when the upper plate 6 enters the hinge portion of the upper slide 61, so that one end of the upper plate 6 and the heat insulation block 42 will be driven by friction effect to move down, the heat insulation block 42 will be driven by one end of the upper plate 6 and the heat insulation block 42 will be contacted with the heat insulation block 42, and the upper plate 10 will gradually enter the lower portion 10 and then the upper portion 10 will be hidden by the upper portion 10 and the lower portion 10 will be separated from the upper portion 10 and the upper portion will be contacted with the lower portion 10.

Specifically, since the upper plate 6 and the lower plate 7 at the upper and lower corresponding positions are arranged in a splayed shape, when the upper plate 6 is pressed after being contacted with the wall surface, a swinging situation occurs, and at this time, the plastic film is not sucked to the suction port 2, and the upper strip 40 is not required to extend out of the upper portion 10, so that the swinging of the upper plate 6 is required to be limited.
In this embodiment, in the course of the body approaching the wall, the wall is contacted with the touch plate 62 and extrudes the touch plate, since the stiffness coefficient of the first elastic member is smaller than that of the second elastic member, the first elastic member is easier to extrude and elastically deform, so that the upper plate 6 is extruded into the upper slide 60 first until one end of the upper slide 60 contacts the heat insulation block 42, then the body is continued to approach the wall, the touch plate 62 is extruded by the wall and starts to retract into the upper plate 6, so that the second elastic member is extruded, so that the limitation between the upper plate 6 and the upper slider 61 is removed, i.e. the swing shaft of the upper plate 6 is provided with the limit friction block 63, when the second elastic member is not deformed by compression, the limit friction block 63 is in frictional contact with the swing shaft to limit the swing of the upper plate 6, and after the second elastic member is deformed by compression, the limit friction block 63 is moved by the touch plate 62 to be separated from the friction limitation of the swing shaft, and then the contact is interacted with the wall when the upper portion 10 approaches the lower portion 11, so that the upper plate 6 can swing.
Preferably, the touch plate 62 is sequentially provided with a plurality of cylindrical balls 64 in a rolling manner along the length direction, the balls 64 are in rolling contact with the wall surface in the horizontal direction, the balls 64 are in friction contact with the wall surface in the longitudinal direction, and cylindrical balls are arranged on the same end part of the lower plate, which is in contact with the wall surface; specifically, when the heat sealing treatment is performed on the portions corresponding to the edges of the two plastic films, intermittent movement of the body is required to substantially heat-seal the portions corresponding to the edges of the two plastic films, so that there is horizontal relative movement of the touch plate 62 and the wall surface member, and in order to reduce friction, cylindrical balls 64 are provided on the touch plate 62, so that rolling contact is made between the balls 64 and the wall surface in the horizontal direction, and friction contact is made between the balls 64 and the wall surface in the longitudinal direction, thereby not affecting movement of the body, but also providing friction for swinging of the upper plate 6.
Referring to fig. 6, in a fifth embodiment of the present invention, further, a blocking member is disposed in the upper portion 10, and the blocking member continuously drives the airflow into the suction port 2 based on the power of the reciprocating mechanism that the upper portion 10 approaches the lower portion 11; the barrier comprises a plurality of barrier plates 9 circumferentially arranged in an upper portion 10, the barrier plates 9 are rotationally arranged in the radial direction, power is transmitted between one end of a rotating shaft of each barrier plate 9 and a shaft lever 15 through gear engagement, and when the surfaces of the barrier plates 9 are parallel to the horizontal plane, the barrier plates generate barriers to gas flow.
Specifically, the suction piece 3 always generates suction force on the plastic film when the heat sealing strip 4 heat seals the plastic film, then the plastic film is melted due to heating, and then the suction force pulls the plastic film, so that the plastic film is torn from the heated and melted part, and the heat sealing performance of the plastic film is reduced, therefore, in this embodiment, when the shaft lever 15 rotates to drive the extrusion block 16 to extrude the extrusion block 17, the power is transmitted to the baffle 9 through gear engagement (such as fixedly connecting a first bevel gear on the shaft lever 15, one end of the rotating shaft of the baffle 9 is fixedly connected with a second bevel gear, and the first bevel gear is meshed with the second bevel gear), so that the surface of the baffle 9 is parallel to the horizontal plane, and a barrier between the suction port 2 and the suction piece 3 is formed, so that air flow is prevented from continuing when the air flow is required, namely, the extrusion block 16 is not extruded any more, the extrusion block 17 is continuously rotated, the power is transmitted to the baffle 9 through the gear engagement, the baffle is radially rotated, and the surface of the baffle is prevented from flowing in the space perpendicular to the baffle 9.
