DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments, based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative work are within the protection scope of the present application.

[0025] The present application will be described in detail below with reference to the drawings and specific embodiments. Embodiment 1

[0026] As Figures 1-6As shown, a steam-proof sealing mold on a wide-mouth bottle sealing machine comprises a bottom plate 1, a pressure bearing plate 11 arranged above the bottom plate 1, a placing groove 12 arranged on the pressure bearing plate 11, a lower mold 13 fixedly connected to the bottom of the placing groove 12, and a mounting plate 14 arranged on the pressure bearing plate 11.

[0027] The top of the mounting plate 14 is fixedly connected with two symmetrically arranged mold connecting blocks 5, and the opposite two sides of the pressure bearing plate 11 are fixedly connected with two mounting racks 51. The opposite two mounting racks 51 are rotatably connected with two rollers 52.

[0028] In use, the two mold connecting blocks 5 are connected with pneumatic pressing rods, the bottle to be sealed is placed in the lower mold 13, then the sealing film is transported above the bottle mouth, the two rollers 52 are used to support the sealing film, then the sealing film is covered on the bottle, and when sealing, the sealing film is pressed down by the film pressing assembly, so that the sealing film is concave downward to seal, thereby avoiding that the steam in the bottle quickly lifts the sealing film to cause the sealed film to separate from the bottle mouth under the action of steam, resulting in unfirm sealing and affecting the sealing effect. In addition, the sealed bottle is pushed out of the lower mold 13 by the material withdrawing assembly, so as to take out the sealed bottle. Embodiment 2

[0029] On the basis of embodiment 1, the film pressing assembly comprises a mounting hole a2, a guide column a21, a spring a22, a heat sealing pressing plate 23, and a film pressing plate 24. A plurality of mounting holes a2 arranged in a ring array are arranged on the mounting plate 14 near the middle position. The mounting holes a2 are each provided with a guide column a21 inside. The guide column a21 is externally sleeved with a spring a22. The bottom ends of the guide columns a21 are fixedly connected with the heat sealing pressing plate 23. The heat sealing pressing plate 23 is provided below with the film pressing plate 24. The film pressing plate 24 and the heat sealing pressing plate 23 are detachably connected through bolts. The film pressing plate 24 is arranged in a circular arc structure. The bottom of the heat sealing pressing plate 23 is fixedly provided with a heat sealing die 25. The heat sealing die 25 is provided between the heat sealing pressing plate 23 with a heating tube 26. The top of the mounting plate 14 is provided with a groove. The terminals at both ends of the heating tube 26 extend into the groove. The heat sealing pressing plate 23 is fixedly provided with a thermocouple 27. The heat sealing die 25 is provided with a knife die 28. The top of the knife die 28 is provided with a plurality of mounting holes b29 arranged in a ring array. The mounting holes b29 are each provided with a guide column b210 inside. The guide column b210 is externally sleeved with a spring b211. The knife die 28 is provided with a knife groove 212. The knife groove 212 is provided with a cutter 213 inside. The cutter 213 is detachably connected with the mounting plate 14 through bolts.

[0030] During sealing, the mounting plate 14 moves downward, pushing the heat-sealing pressing plate 23, the film pressing plate 24, the cutting die 28 and the cutter 213 downward through the guide pillars a21 and b210. Since the film pressing plate 24 is at the bottom, the film pressing plate 24 first contacts the sealing film, and the sealing film moves downward and is recessed under the action of the film pressing plate 24. Then the heat-sealing die 25 presses the sealing film and contacts the bottle mouth, thereby pressing the sealing film and preventing the sealing film from moving. Since the film pressing plate 24 and the heat-sealing die 25 cannot continue to move downward to push the sealing film, the mounting plate 14 moves downward along the outside of the guide pillar a21 under the reaction force, and at the same time, the spring a22 is squeezed and contracts to store energy. The mounting plate 14 continues to move downward and pushes the film pressing plate 24 to contact the pressure-bearing plate 11 through the guide pillars b210. Affected by the reaction force of the pressure-bearing plate 11, the mounting plate 14 moves downward along the outside of the guide pillars b210 to squeeze the spring b211, and the cutter 213 continues to move downward. The cutter 213 moves along the inside of the knife groove 212 on the cutting die 28, and the cutter 213 moves downward to cut the sealing film. Then the heating tube 26 is started to make the bottom of the heat sealing die 25 weld the sealing film and the bottle mouth together. The thermocouple 27 can check the temperature. By measuring the voltage of the heating tube 26 by the thermocouple 27, the temperature can be calculated, so that the temperature can be accurately known and adjusted in time. Then, after the sealing is completed, the mounting plate 14 moves downward, driving the heat sealing pressing plate 23, the film pressing plate 24, the cutting die 28 and the cutter 213 to move upward and separate from the bottle mouth. At this time, the sealed film is concave under the pressure of the film pressing plate 24, thereby reserving space for steam to rise. The steam slowly bulges the sealing film during the continuous evaporation process. During the bulging time of the sealing film, the dissolved part of the bottle mouth and the sealing film cools, making the sealing film connection firm, thereby preventing the sealing film from bulging quickly and separating the dissolved part between the bottle mouth and the sealing film to affect the sealing performance.

[0031] Among them, four equally spaced mounting holes c4 are opened on the top of the pressure plate 11, and pressure columns 41 are arranged inside the mounting holes c4. The bottom ends of the four pressure columns 41 are connected to the pressure plate 11, and springs c42 are arranged on the outside of the pressure columns 41.

[0032] When the mounting plate 14 moves downward, it moves along the outside of the four pressure-bearing columns 41, thereby guiding the mounting plate 14. When moving, the mounting plate 14 presses the spring c42 downward, and the spring c42 can buffer the downward pressure of the mounting plate 14. Example 3

[0033] On the basis of embodiment 1, the material returning assembly comprises a top material plate 3, a fixed column 31, a connecting plate 32, a sliding sleeve 33 and a pneumatic cylinder 34, the top of the bottom plate 1 is provided with the top material plate 3, the top of the bottom plate 1 and the bottom of the pressure bearing plate 11 are fixedly connected with the fixed column 31 near the four corner positions respectively, the top material plate 3 is fixedly connected with four connecting plates 32 which are equidistantly distributed, the connecting plates 32 are fixedly connected with the sliding sleeves 33 at one end respectively, the four sliding sleeves 33 are respectively sleeved outside the four fixed columns 31, the pneumatic cylinder 34 is fixedly installed at the bottom of the bottom plate 1 near the center position, and the piston rod at the top end of the pneumatic cylinder 34 is connected with the bottom of the top material plate 3.

[0034] After the bottle is sealed, the piston rod of the pneumatic cylinder 34 is pushed out, the top material plate 3 is pushed up by the piston rod, and the bottle is pushed out of the lower mold 13, so that the sealed bottle is taken out, and at the same time, the sliding sleeve 33 is driven to slide along the outside of the fixed column 31 by the connecting plate 32 when the top material plate 3 moves, so as to limit the moving route of the top material plate 3, and the top material plate 3 moves stably. After the bottle is taken out, the piston rod of the pneumatic cylinder 34 is retracted, the top material plate 3 is driven to move downward to the initial position, so as to be ready for placing the next bottle.
