Abstract
A vacuum disc aspirator is an annular circle body made of elastic and soft material which is characterized in that the wall of the upper half part is thinner than that of the lower half part and the inner diameter of the upper half part is bigger than that of lower half part. The utility model can occur elastic deformation easily due to the thin wall of the upper half part and the bigger inner diameter, so when the vacuum disc aspirator pumps vacuum, the upper half part of the vacuum disc aspirator deforms and clings to the sealing membrane thus to suck the sealing membrane which can't make the sealing membrane deform easily and put the sealing membrane at the needed place neatly, the vacuum disc aspirator has advantages of good sealing quality, low defective product rate and assurance of the normal production.
Description
Technical field
The utility model relates to a kind of vacuum cup that is used on the filling sealer closing device.
Background technology
Be used for the vacuum cup on the filling sealer closing device at present, the overwhelming majority can both hold reliably and seal film during use, but vacuum cup hold seal film particularly thin seal film the time, seal film and be easy to generate distortion, periphery is wrinkling, have a strong impact on seal quality, the fraction defect height causes harmful effect to ordinary production.
Summary of the invention
The purpose of this utility model provides a kind of can holding reliably and seals film and be difficult for making the vacuum cup that seals the film distortion.The technical scheme that adopts is as follows:
A kind of vacuum cup, it is the ring-type circle body of being made by the elasticity flexible material, it is characterized in that: the wall of the described ring-type circle body first half is thinner than the wall of lower part, and the internal diameter of the first half is bigger than the internal diameter of lower part.
The wall of the ring-type circle body first half should approach as far as possible, and the wall ratio of the ring-type circle body first half sealed more easy deformation of film when vacuum cup was vacuumized.The internal diameter of the ring-type circle body first half is big, more helps making sucker periphery suction even.The wall of ring-type circle body lower part is thicker, and is not yielding, is convenient to vacuum cup is fixed on the sucker disk seat.
The internal diameter of the preferred ring-type circle body first half increases from the bottom to top gradually, and more preferably the ring-type circle body first half is circular cone shape, and cone apex angle is preferably 140 °～160 °; The attenuation gradually from the bottom to top of the wall of the ring-type circle body first half, ring-type circle body first half easy deformation when vacuum cup is vacuumized, and be close to the film that seals that is held.
The internal diameter of ring-type circle body lower part is as far as possible big, helps making when vacuumizing sucker periphery suction more even like this.
Preferred vacuum chuck is made by good springiness and difficult aging engineering rubber.
The utility model is because the wall of the ring-type circle body first half is thin and internal diameter is bigger, elastic deformation takes place easily, when therefore suction dish inside vacuumizes surely, the distortion of the vacuum cup first half also is close to and is sealed film, to seal film and hold and be difficult for making and seal film distortion, and will seal film and entirely be placed into desired location, seal quality is good, fraction defect is extremely low, and that guarantees to produce normally carries out.
Description of drawings
Accompanying drawing is the structural representation (cutaway view) of the utility model one preferred embodiment.
The specific embodiment
As shown in drawings, this vacuum cup is the ring-type circle body of being made by good springiness and difficult aging engineering rubber, and the wall of the ring-type circle body first half 1 is thinner than the wall of lower part 2, and the internal diameter of the first half 1 is bigger than the internal diameter of lower part 2.
In actual applications, the wall of the ring-type circle body first half 1 should approach as far as possible, and the wall ratio of the ring-type circle body first half 1 sealed more easy deformation of film when vacuum cup was vacuumized; The internal diameter of the ring-type circle body first half 1 is big, more helps making sucker periphery suction even.The wall of ring-type circle body lower part is thicker, and is not yielding, is convenient to vacuum cup is fixed on the sucker disk seat.
The internal diameter of the ring-type circle body first half 1 increases from the bottom to top gradually, and the ring-type circle body first half 1 is circular cone shape, and cone apex angle is 145 °; The attenuation gradually from the bottom to top of the wall of the ring-type circle body first half 1.
The upper surface of ring-type circle body is adjacent to by suction and seals film during work, when to vacuum cup inside (being ring-type circle body inside) when vacuumizing, the ring-type circle body first half 1 highly descends, is out of shape, and hold sealing film, filling sealer moves vacuum cup (being the ring-type circle body) and is placed into desired location sealing film.
Claims (5)
1, a kind of vacuum cup, it is the ring-type circle body of being made by the elasticity flexible material, it is characterized in that: the wall of the described ring-type circle body first half is thinner than the wall of lower part, and the internal diameter of the first half is bigger than the internal diameter of lower part.
2, vacuum cup according to claim 1 is characterized in that: the internal diameter of the described ring-type circle body first half increases from the bottom to top gradually.
