Claims

1. A sealing and locking mechanism, characterized in that, include: A machine body having a conveyor belt for conveying containers with external threads and fitting container lids with internal threads onto the containers; a base is located above the conveyor belt, and an inner wall is formed within the base; and A tightening unit is disposed within the machine base. The tightening unit includes a drive wheel and a driven wheel assembly, which are arranged opposite to each other and wound with a first belt and a second belt respectively. The length ratio of the first belt to the second belt is 1:1.5, so that the two belts rotate at different speeds. When the container passes under the first belt and the second belt via the conveyor belt, the top surface of the container lid is pushed by the friction of the two belts to generate torque, causing the container lid to be screwed into the external thread of the container, thereby achieving a tightening and sealing.

2. The sealing and locking mechanism as described in claim 1, characterized in that, The linear speed of the first belt ranges from 1.0 m / s to 1.5 m / s, and the linear speed of the second belt ranges from 0.6 m / s to 1.0 m / s, with a speed difference between the two ranging from 0.2 m / s to 0.5 m / s.

3. The sealing and locking mechanism as described in claim 1, characterized in that, The outer layer of both the first belt and the second belt is covered with an elastic friction layer, which is made of rubber or polyurethane, and the torque generated by the friction layer is in the range of 0.3 N·m to 0. N·m.

4. The sealing and locking mechanism as described in claim 1, characterized in that, The drive wheel includes a drive shaft, one end of which extends into the inner wall of the base, and the other end is provided with a first wheel body and a second wheel body, wherein the diameter of the second wheel body is larger than that of the first wheel body; The driven wheel assembly includes a first wheel seat and a second wheel seat. The first wheel seat has a first frame, in which a first shaft is pivotally mounted and a first guide wheel is pivotally mounted. A connecting frame is provided at the bottom of the first frame, and a first pivot seat is formed at the bottom of the connecting frame. The first pivot seat has a first pivot hole. The second wheel seat has a second bracket, the second bracket is provided with a second frame, a second shaft is pivotally mounted inside the second frame, and a second guide wheel is pivotally mounted by the second shaft. The bottom of the second bracket is provided with a second pivot seat, and the second pivot seat is provided with a second pivot hole. The first wheel seat and the second wheel seat are respectively assembled on a lifting adjustment seat. The lifting adjustment seat has two adjacent hangers, each hanger having a lifting hole. One end of the lifting adjustment seat has a guide end, and the bottom surface forms a bottom sliding surface. A side guide flange is provided on both sides of the bottom sliding surface. The other end of the lifting adjustment seat has a pivot seat, which is pivotally mounted on the first pivot seat and the second pivot seat. A third guide wheel is provided between the first pivot seat and the pivot seat, and a fourth guide wheel is provided between the second pivot seat and the pivot seat. The system comprises two lifting frames, each equipped with a mounting base. The mounting base has a through-hole and is pivotally connected to the lifting adjustment seat's mounting hole via a fixing pin. The lifting frames are integrated into a base frame, with a lifting adjustment knob at its top. This knob drives a guide shaft via a worm gear mechanism, which in turn drives a worm wheel / sprocket mechanism to drive a first chain and a second chain. The ends of the first and second chains mesh with a first sprocket and a second sprocket, respectively. These sprockets are mounted on the two lifting frames and drive the lifting adjustment seat to rise and fall synchronously, making the height of the first and second belts relative to the conveyor belt adjustable. One end of the guide shaft is connected to the worm gear mechanism, and the other end is fixed to the worm wheel / sprocket mechanism. When the worm wheel rotates under the drive of the worm gear, it synchronously drives the sprocket to rotate, which in turn drives the first and second sprockets via the first and second chains, causing the two lifting frames to rise and fall synchronously.

5. The sealing and locking mechanism as described in claim 4, characterized in that, The first wheel seat has a first pivot lug on its connecting frame, and the second wheel seat has a second pivot lug on its second bracket. The inner wall of the base has a fixed support column and a fixed support. The first pivot lug and the second pivot lug are respectively pivotally mounted with a tension adjustment bracket. The tension adjustment bracket has a pivot end, which has a pivot connection part and a pivot connection hole, and can be fixed to the first pivot lug and the second pivot lug by a positioning pin. One end of the pivot assembly is connected to a telescopic frame, which contains a guide post. An elastic component is fitted between the guide post and the telescopic frame. One end of the guide post has a multi-segment positioning part. The side edge of the positioning part forms multiple slots with different spacings. Each slot can selectively engage with the fixed support for positioning, so that the tension of the first wheel seat and the second wheel seat can be adjusted by the elastic telescopic engagement of the multi-segment positioning part of the tension adjustment bracket with the guide post.

6. The sealing and locking mechanism as described in claim 1, characterized in that, The machine base is equipped with a cooling pipe that can spray water to cool the first belt and the second belt.

7. The sealing and locking mechanism as described in claim 1, characterized in that, The conveyor belt has two support belts on both sides to support the containers being transported.
