DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5 In an embodiment of the present invention, a continuous sealing device based on freely adjustable spacing includes a base 10, a conveyor belt 11 and a sealing mechanism, wherein the sealing mechanism includes an upper sealing component 20 and a lower sealing component 30 that cooperate with each other, and a sealing gap for material to pass through is formed between the upper sealing component 20 and the lower sealing component 30. It should be noted that in this embodiment, the material to be sealed is a packaging bag. When the opening of the packaging bag passes through the sealing gap, the upper sealing component 20 and the lower sealing component 30 cooperate with each other to perform hot pressure sealing on the opening of the packaging bag; the conveyor belt 11 is installed on the base 10, and the conveyor belt 11 is used to drive the packaging bag to move so that the opening of the packaging bag passes through the sealing gap. A frame 12 is fixedly installed on the base 10, and a front baffle 14 is provided on the front side of the frame 12. The upper sealing component 20 and the lower sealing component 30 are installed on the frame 12, and the sealing gap between the upper sealing component 20 and the lower sealing component 30 is in the same plane as the surface of the conveyor belt 11.

[0024] In the embodiment of the present application, the upper sealing assembly 20 includes a hot pressing head 22, a first feed roller 21 and a first discharge roller 23 arranged on both sides of the hot pressing head 22, and a mounting plate, the hot pressing head 22 is fixedly connected to the mounting plate, and the first feed roller 21 and the first discharge roller 23 are rotatably connected to the mounting plate; a guide groove 221 is provided on the upper side of the hot pressing head 22, and the upper side of the hot pressing head 22 is connected to the frame 12 through at least one spring column 24, a telescopic rod 13 is fixedly installed on the frame 12, and a top block 222 that cooperates with the guide groove 221 is installed at the telescopic end of the telescopic rod 13, a hot pressing plate 25 is installed on the lower side of the hot pressing head 22, and the conveyor belt 11 drives the packaging bag to move When it moves to the first feed roller 21, the first feed roller 21 in a rotating state brings the opening of the packaging bag into the sealing gap. Since the thickness of the packaging bag and its opening are different, the opening of the packaging bag will squeeze the first feed roller 21 and the hot pressing head 22 in the process of entering the sealing gap, thereby causing the spring column 24 to deform. The sealing gap adaptively adjusts the width according to the packaging bag, and changes the spacing between the upper sealing assembly 20 and the lower sealing assembly 30. When the opening of the packaging bag enters the sealing gap, the telescopic end of the telescopic rod 13 extends, driving the top block 222 to slide along the guide groove 221. When the top block 222 reaches the bottom of the guide groove 221, the top block 222 squeezes the hot pressing head 22, so that the opening of the packaging bag on the hot pressing plate 25 is sealed.

[0025] It should be noted that, in this embodiment, the structure of the lower sealing assembly 30 is similar to that of the upper sealing assembly 20. The lower sealing assembly 30 includes a hot pressing seat and a second feed roller and a second discharge roller arranged on both sides of the hot pressing seat. The second feed roller is located directly below the first feed roller 21. Figure 2 For example, the first feed roller 21 rotates clockwise and the second feed roller rotates counterclockwise to bring the packaging bag into the sealing gap; the second discharge roller is located directly below the first discharge roller 23, the first discharge roller 23 rotates clockwise and the second discharge roller rotates counterclockwise to discharge the packaging bag out of the sealing gap.

[0026] In addition, in the embodiment of the present application, a feed motor 211 for driving the first feed roller 21 to rotate and a discharge motor 231 for driving the first discharge roller 23 to rotate are also fixedly mounted on the mounting plate.

[0027] In the embodiments of this application, Figure 3 As shown, the feed mechanism 40 is fixedly mounted on the base 10, and the feed mechanism 40 is located above the feeding side of the conveyor belt 11. The feed mechanism 40 includes a feed box 41, a guide seat 42 and a baffle plate 43. The upper side of the feed box 41 is provided with a feed inlet, and the lower side of the feed box 41 is provided with a discharge outlet. The feed box 41 is used to store the materials to be sealed; the guide seat 42 is fixedly mounted on the lower side of the feed box 41, and the baffle plate 43 is slidably mounted on the bottom of the guide seat 42. The side of the baffle plate 43 is fixedly mounted with a rack 44. The guide seat 42 is rotatably mounted with a fan gear 45, and the fan gear 45 is meshed with the rack 44. When the fan gear 45 drives the rack 44 to move, the baffle plate 43 moves toward the discharge outlet until it blocks the discharge outlet. At this time, the materials inside the feed box 41 cannot fall onto the conveyor belt 11. After the baffle plate 43 leaves the discharge outlet, the materials fall onto the conveyor belt 11;

[0028] Furthermore, in the embodiment of the present application, a guide rod 46 is fixedly installed on one side of the feed box 41, and the side edge of the baffle plate 43 is slidably connected to the guide rod 46, and a connecting spring 47 is sleeved on the guide rod 46 to drive the baffle plate 43 to return to its original position. When the baffle plate 43 moves toward the discharge port and blocks the discharge port, the connecting spring 47 is in a compressed state, and then the sector gear 45 is separated from the rack 44, and the connecting spring 47 drives the baffle plate 43 to return to its original position, and the discharge port is opened.

[0029] Furthermore, in an embodiment of the present application, a drive motor 112 is installed on the base 10, and the drive motor 112 drives the conveyor belt 11 through the conveyor belt shaft. The conveyor belt shaft is connected to the shaft of the sector gear 45 through a synchronous belt 48. It can be understood that during the continuous operation of the conveyor belt 11, the conveyor belt shaft drives the sector gear 45 to rotate continuously through the synchronous belt 48, and the sector gear 45 is intermittently in contact with the rack 44 to achieve intermittent unloading of the material to be sealed.

[0030] In addition, it should be noted that a number of horizontal bars 111 are evenly arranged on the conveyor belt 11. The horizontal bars 111 can be used to push the material to move, so that the material squeezes the upper sealing component 20, so that it can smoothly enter the sealing gap formed between the upper sealing component 20 and the lower sealing component 30.
