[0020] One embodiment of the automatic sealing machine applied to the plastic bottle is shown in the drawings.Figs. 1-3 , comprising a conveying assembly 1, a heating assembly 2 and a sealing assembly 3, the heating assembly 2 and the sealing assembly 3 are sequentially arranged along the conveying direction of the conveying assembly 1, the bottom of the heating assembly 2 is provided with a heating area 211, the heating area 211 is located above the conveying assembly 1, the sealing assembly 3 comprises a driving sealing wheel 31 and a driven sealing wheel 32, the driving sealing wheel 31 and the driven sealing wheel 32 are arranged above the conveying assembly 1, and the conveying assembly 1 is used to drive the plastic bottle 6 to be sealed to pass through the heating area 211 and between the driving sealing wheel 31 and the driven sealing wheel 32.
[0021] The embodiment drives the formed plastic bottle 6 to sequentially pass through the heating assembly 2 and the sealing assembly 3 through the conveying assembly 1, so that the bottle opening part of the plastic bottle 6 is softened under the heating of the heating assembly 2, and then is extruded by the driving sealing wheel 31 and the driven sealing wheel 32, so as to realize the closure of the softened bottle opening part, thereby avoiding the pollution in the traditional transportation or storage process, saving the production process of cleaning and disinfection, and saving the cost. Only the closed bottle opening part needs to be cut before subsequent filling, so that normal filling can be realized, and the raw material of the cut bottle opening part can be recycled for secondary use, thereby avoiding the waste of plastic raw material. Therefore, the embodiment realizes the automatic processing of the heating and sealing of the bottle opening part of the plastic bottle 6 by arranging the conveying assembly 1, the heating assembly 2 and the sealing assembly 3, which not only effectively avoids the pollution of the plastic bottle 6 in the transportation and storage process, but also greatly reduces the manual operation link and reduces the production cost.
[0022] Preferably, the heating assembly 2 comprises an infrared lamp tube, a heating box body 21 and a box body support 22, the box body support 22 is arranged on both sides of the conveying assembly 1, the heating box body 21 is arranged on the box body support 22, the infrared lamp tube is arranged in the heating box body 21, and the bottom of the heating box body 21 is provided with a heating area 211 parallel to the conveying assembly 1.
[0023] The infrared lamp tube is used as the heating source, and the infrared lamp tube is arranged in the heating box body 21, so that the infrared radiation energy is more concentrated and uniformly transmitted to the heating area 211, thereby acting on the bottle opening part of the plastic bottle 6. The infrared heating has the advantages of fast response and high heating efficiency, and under the driving of the conveying assembly 1, the plastic bottle 6 can continuously and stably pass through the heating area 211 in the conveying process, and receive uniform and sufficient heating treatment, so that the bottle opening part of the plastic bottle 6 is softened to a suitable sealing state under the heating. Since only the bottle opening part enters the heating area 211, the over-heating of other parts of the bottle body is avoided, and the overall structural stability of the plastic bottle 6 is maintained.
[0024] Preferably, the sealing assembly 3 comprises a motor support 33 and a sealing motor 34, the motor support 33 is arranged above the conveying assembly 1, the sealing motor 34 is vertically arranged on the motor support 33, the driving sealing wheel 31 is arranged at the end of the rotating shaft of the sealing motor 34, and the driven sealing wheel 32 is arranged on the motor support 33 through a bearing.

[0026] Preferably, the conveying assembly 1 comprises two groups of lateral conveying units 11, which are arranged left and right, and a conveying channel 111 for clamping and conveying the plastic bottle 6 is formed between the two groups of lateral conveying units 11.
[0027] The plastic bottle 6 is conveyed in the conveying channel 111 formed between the two groups of lateral conveying units 11, that is, the two groups of lateral conveying units 11 clamp the two sides of the plastic bottle 6 during the conveying process, thereby ensuring the stability and accuracy of the plastic bottle 6 during the conveying process, effectively preventing the plastic bottle 6 from tilting, rolling or falling during the conveying process, and also ensuring that the plastic bottle 6 passes through the heating assembly 2 and the sealing assembly 3 in the correct posture, and ensuring that the bottle mouth of the plastic bottle 6 is heated and sealed. By adjusting the distance between the two groups of lateral conveying units 11, different diameters and shapes of plastic bottles 6 can be easily adapted, meeting the production needs of plastic bottles 6 of different shapes.

The contact surface of the clamping rubber block 114 and the plastic bottle 6 is soft and smooth, which can avoid scratching or wearing the surface of the plastic bottle 6 and ensure the quality of the plastic bottle 6 product.
[0032] Preferably, the discharge hopper 4 is further included, and the discharge hopper 4 is arranged at the end of the conveying assembly 1.
