DETAILED DESCRIPTION

[0026] As Figures 1-6As shown, this utility model provides a technical solution: a sealing device for tea beverage packaging, including a frame 1, a conveyor belt 2 installed on the top of the frame 1, a fixed frame 4 fixed on the top of the frame 1, a cylinder 5 fixed on the surface of the fixed frame 4, the output end of the cylinder 5 passing through the fixed frame 4, a connecting frame 6 fixed on the output end of the cylinder 5, a heating block 7 fixed on the surface of the connecting frame 6, and a cleaning component 8 and a limiting component 9 provided on the surface of the connecting frame 6; the cleaning component 8 includes: a motor 80, a reciprocating lead screw 81, a concave rod 82, a slide rod 83, a concave frame 84, a sliding plate 85, a spring 86, a scraper 87, and a spring 88.

[0027] The motor 80 is fixed to the surface of the connecting frame 6. The output shaft of the motor 80 passes through the connecting frame 6. A reciprocating lead screw 81 is rotatably connected to the inner wall of the connecting frame 6. The output shaft of the motor 80 is fixed to the surface of the reciprocating lead screw 81. A concave rod 82 passes through the reciprocating lead screw 81 and is threadedly connected to the reciprocating lead screw 81. A slide rod 83 is provided on the surface of the concave rod 82. The slide rod 83 passes through the concave rod 82 and is slidably connected to the concave rod 82. A concave frame 84 is fixed to the surface of the slide rod 83. A spring 88 is fixed to the concave frame 84. One end away from the concave frame 84 is fixed to the surface of the concave rod 82. A slide plate 85 is slidably connected to the inside of the concave frame 84. A spring 86 is fixed to the surface of the slide plate 85. One end of the spring 86 away from the slide plate 85 is fixed to the inside of the concave frame 84. A scraper 87 is fixed to the side of the slide plate 85 away from the spring 86. When the motor 80 is turned on, the reciprocating screw 81 drives the concave rod 82 to reciprocate. At this time, the concave rod 82 drives the scraper 87 to move closer to the L-shaped plate 91. The surface of the scraper 87 is in contact with the surface of the heating block 7, so that the surface of the heating block 7 can be cleaned.

[0028] The limiting component 9 includes an abutment groove 90, which is formed on the surface of the scraper block 87. An L-shaped plate 91 is fixed to the surface of the connecting frame 6. A fixing plate 92 is fixed to the side of the sliding plate 85 away from the scraper block 87. A locking block 93 is fixed to the surface of the fixing plate 92. A fixing plate 94 is fixed to the inner side of the concave frame 84. A spring 95 is fixed to the surface of the fixing plate 94. An L-shaped plate 96 is fixed to the end of the spring 95 away from the fixing plate 94. The L-shaped plate 96 is slidably connected to the inner side of the concave frame 84. An L-shaped rod 98 is fixed to the end of the connecting frame 6 away from the motor 80. A groove 99 is formed on the surface of the L-shaped rod 98. An L-shaped rod 97 is slidably connected to the inner wall of the groove 99. A spring 900 is fixed to the surface of the L-shaped rod 97. The end of the spring 900 away from the L-shaped rod 97 is fixed to the inner wall of the groove 99. The locking block 93 is positioned on the side away from the fixing plate 92. The contact groove 90 is set as an inclined surface. When the scraper 87 is located at the outermost edge of the connecting frame 6, the surface of the L-shaped plate 91 abuts against the inclined surface of the contact groove 90, and the scraper 87 moves away from the concave rod 82. The surface of the L-shaped plate 96 abuts against the side of the locking block 93 away from the inclined surface, limiting the fixed plate 92 and the scraper 87. At this time, the scraper 87 moves away from the heating block 7. When the concave rod 82 moves away from the L-shaped plate 91, the scraper 87 will not move dust and impurities, avoiding affecting the cleaning. When the concave rod 82 is located on the side away from the L-shaped plate 91, the L-shaped rod 97 abuts against the L-shaped plate 96. At this time, the L-shaped plate 96 disengages from the locking block 93, releasing the limitation on the fixed plate 92 and the scraper 87. At this time, the spring 86 is released, driving the scraper 87 to reset and re-fit against the surface of the heating block 7. Thus, when the motor 80 is working continuously, the scraper 87 reciprocates and fits against the heating block 7, improving the cleaning efficiency. The surface of the conveyor belt 2 is equipped with a placement rack 3 for convenient and stable packaging.

[0029] In use, the package containing tea is placed inside the placement rack 3 and transported via the conveyor belt 2. When the package is positioned between the heating blocks 7, the cylinder 5 is activated, causing the connecting frame 6 to move closer to the package, allowing the heating blocks 7 to seal it. Simultaneously, as the heating blocks 7 approach each other, the concave frames 84 abut against each other, causing them to move closer to the concave rod 82. At the same time, L-shaped rod 1 97 moves closer to L-shaped rod 2 98, without affecting the normal sealing process. When the heating blocks 7 need surface treatment... During cleaning, the motor 80 is turned on, and the reciprocating screw 81 drives the concave rod 82 to reciprocate. At this time, the concave rod 82 drives the scraper 87 to move closer to the L-shaped plate 91. The surface of the scraper 87 is in contact with the surface of the heating block 7, which can clean the surface of the heating block 7. When the scraper 87 is at the outermost edge of the connecting frame 6, the surface of the L-shaped plate 91 is in contact with the inclined surface of the contact groove 90, which can drive the scraper 87 away from the concave rod 82. At this time, the spring 86 is compressed, and the fixing plate 92 and the locking block 93 are pressed together. As the L-shaped plate 96 moves closer, the inclined surface of the locking block 93 abuts against the surface of the L-shaped plate 96, causing the L-shaped plate 96 to move closer to the fixed plate 94. The spring 95 is compressed. When the side of the locking block 93 away from the inclined surface is parallel to the L-shaped plate 96, the spring 95 is released, and the L-shaped plate 96 returns to its original position. Simultaneously, the surface of the L-shaped plate 96 abuts against the side of the locking block 93 away from the inclined surface, thus limiting the position of the fixed plate 92 and the scraper block 87. At this time, the scraper block 87 moves away from the heating block 7. When the concave rod 82 moves away from the L-shaped plate 91... When moving, the scraper 87 will not move dust or impurities, thus avoiding affecting cleaning. When the concave rod 82 is located away from the L-shaped plate 91, the L-shaped rod 97 abuts against the L-shaped plate 96. At this time, the L-shaped plate 96 disengages from the locking block 93, releasing the restriction on the fixing plate 92 and the scraper 87. At this time, the spring 86 is released, causing the scraper 87 to reset and re-fit against the surface of the heating block 7. Thus, when the motor 80 is working continuously, the scraper 87 reciprocates and fits against the heating block 7, improving cleaning efficiency.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
