A roller cleaning plate 14 is fixedly connected to one side of the roller support seat 122. The roller cleaning plate 14 is located on the back of the auxiliary transmission roller 13. A brush is fixedly connected to the front of the roller cleaning plate 14. A conveyor belt cleaning component 15 is fixedly connected to one side of the roller support seat 122. The conveyor belt cleaning component 15 is located on the front of the auxiliary transmission roller 13. The conveyor belt cleaning component 15 includes a supporting frame 151. The supporting frame 151 is fixedly connected to one side of the roller support seat 122. The side of the supporting frame 151 is fixedly connected to the other side of the roller support seat 122. A circular blind hole is fixedly connected to the top of the supporting frame 151. A rectangular blind hole is fixedly connected to the bottom of the circular blind hole. The number of circular blind holes is 22 and is evenly distributed on the top of the supporting frame 151. A sliding rod 152 is slidably connected inside the circular blind hole of the supporting frame 151. A sliding bottom plate 153 is fixedly connected to the bottom of the sliding rod 152. One side of the sliding bottom plate 153 is slidably connected to the rectangular blind hole of the supporting frame 151. The bottom of the sliding bottom plate 153 is fixedly connected to the bottom of the rectangular blind hole of the supporting frame 151 through a spring. The top of the sliding rod 152 is fixedly connected with an inclined bottom plate 154, the front of the inclined bottom plate 154 is rotatably connected with an inclined plate 155 through a rotating shaft, the bottom of the inclined plate 155 is fixedly connected to the top of the inclined bottom plate 154 through a spring, and the top of the inclined plate 155 is fixedly connected with a brush, and the number of the supporting slide 12, the auxiliary transmission roller 13, the roller cleaning plate 14, and the conveyor belt cleaning assembly 15 is four, and the positions of the supporting slide 12, the auxiliary transmission roller 13, the roller cleaning plate 14, and the conveyor belt cleaning assembly 15 are all aligned with the four rectangular blind holes inside the main frame 11. The positions of the holes are consistent. The transmission auxiliary frame 1 adapts to the diameter of the tubular conveyor belt autonomously with the cooperation of the spring, and appropriately compresses the tubular conveyor belt, reducing the probability of the conveyor belt sealing opening increasing due to looseness, and improving the sealing of the conveyor belt in the closed transportation stage. The transmission auxiliary frame 1 absorbs part of the vibration caused by various factors through the spring, reducing the probability of the material in the conveyor belt flying out along the opening that may appear at the conveyor belt sealing due to the vibration of the conveyor belt, and assists in improving the cleanliness of the environment around the conveyor belt, thereby improving the conveying effect of the conveyor belt; The back of the main frame 11 is fixedly connected with a sealer 2, the top of the sealer 2 is fixedly connected with an air intake assembly 3, the transmission auxiliary frame 1 is slidably connected with a conveyor belt body 4, and the conveyor belt body 4 is driven by an external driving device to realize the movement of the conveyor belt body 4.

[0022] When in use, before the conveying work is carried out, the devices are fixed in series in sequence according to the length of the route of closed conveying required to form a device combination. After the fixing is completed, the conveyor belt body 4 is rolled into a closed state and passed through the front of the transmission auxiliary frame 1 until the conveyor belt body 4 passes through all the transmission auxiliary frames 1 and leaves the device combination. After the placement of the conveyor belt body 4 of the entire transmission line is completed, the conveyor belt body 4 is driven to slide by starting an external driving device, and the air intake component 3 is controlled to start by the external power distribution equipment, and the conveyor belt body 4 in contact with the transmission auxiliary frame 1 slides backward in a closed state, and the conveyor belt body 4 entering the device combination from the outside gradually changes from a U shape to a closed state, and the conveyor belt body 4 leaving the device combination from the transmission auxiliary frame 1 gradually changes from a closed state to a U shape; During the movement of the conveyor belt body 4, the outer surface of the conveyor belt body 4 and the surface of the auxiliary driving roller 13 slide relative to each other, and at the same time, the outer surface of the conveyor belt body 4 squeezes the auxiliary driving roller 13, and then squeezes the supporting slide 12 through the auxiliary driving roller 13, so that the surrounding supporting slides 12 slide along the rectangular blind holes of the main frame 11, and squeezes the spring at the same time. After being squeezed by the supporting slide 12, the spring exerts a reverse force, and the reverse force acts on the surface of the conveyor belt body 4 through the auxiliary driving roller 13, so as to fix the surrounding of the conveyor belt body 4, especially enhance the fixation of the sealing part at the top of the conveyor belt body 4, and reduce the probability of its sealing loosening due to unstable fixation; During the movement of the conveyor belt body 4, the outer surface of the conveyor belt body 4 squeezes the brush on the top of the inclined plate 155, thereby allowing the sliding rod 152 and the sliding bottom plate 153 to slide along the inside of the supporting frame 151 and squeeze the spring. The inclined plate 155 rotates left and right under the squeezing of the outer surface of the conveyor belt body 4. At the same time, the inclined plate 155 squeezes the spring on the side moving downward and stretches the other side, thereby increasing the contact area between the inclined plate 155 and the surface of the conveyor belt body 4. The spring allows the brush on the top of the inclined plate 155 to be in firm contact with the outer surface of the conveyor belt body 4. As the conveyor belt body 4 slides, the brush scrapes off large impurities that may be attached to or slightly embedded in the outer surface of the conveyor belt body 4, reducing the damage to the outer surface of the conveyor belt body 4 and preventing the large impurities from causing vibration of the conveyor belt body 4 and damaging the surface of the auxiliary drive roller 13 when passing through the auxiliary drive roller 13. At the same time, the brush of the roller cleaning plate 14 scrapes the surface of the auxiliary drive roller 13 to clean up the large impurities that may adhere to or slightly embed on the surface of the auxiliary drive roller 13 during the movement of the conveyor belt body 4.

[0023] Example 2: Please refer to Figure 1-8On the basis of the first embodiment, the present invention provides a technical solution: the sealing device 2 includes a sealing slide box 21, the interior of the sealing slide box 21 is a hollow structure, the top of the sealing slide box 21 is connected with a circular blind hole, the bottom of the sealing slide box 21 is connected with a rectangular blind hole, the bottom of the sealing slide box 21 is slidably connected with a sealing ventilation slide 22 through the rectangular blind hole, the sealing ventilation slide 22 includes a slide seat 221, one side of the slide seat 221 is slidably connected to one side of the inner wall of the sealing slide box 21, the top of the slide seat 221 is fixedly connected with a circular blind hole, the bottom of the circular blind hole of the slide seat 221 is connected with the rectangular blind hole, the bottom of the slide seat 221 is connected with a seal mounting frame 222, the bottom of the seal mounting frame 222 is fixedly connected with a rectangular blind hole, and is connected to the inside of the slide seat 221 The rectangular blind hole is connected to the seal mounting frame 222, and the seal mounting frame 222 is connected to a flexible sealing strip 223. The flexible sealing strip 223 is made of rubber, and a cross-section of one side of the flexible sealing strip 223 is a right-angled trapezoid. The bottom of the flexible sealing strip 223 is connected to a rectangular through hole, and the rectangular through hole at the bottom of the flexible sealing strip 223 is connected to the rectangular blind hole at the bottom of the seal mounting frame 222. There are two seal mounting frames 222 and two flexible sealing strips 223, and they are symmetrically distributed at the bottom of the slide seat 221. A flexible sealing roller 23 is rotatably connected inside the sealing ventilation slide 22. The flexible sealing strip 223 passes through the area near the seal of the conveyor belt, thereby increasing the contact area between the sealer and the conveyor belt, increasing the closing range, and thereby improving the sealing of the conveyor belt seal.

[0024] When in use, when the top of the conveyor belt body 4 contacts the bottom of the sealer 2 after passing through the transmission auxiliary frame 1, the top of the conveyor belt body 4 contacts the bottom of the flexible sealing strip 223, thereby lifting the flexible sealing strip 223 upward, and the flexible sealing strip 223 drives the slide seat 221 to slide upward through the sealing strip mounting frame 222. The top of the slide seat 221 slides upward while squeezing the spring. After being squeezed, the spring exerts a reverse force and finally acts on the surface of the conveyor belt body 4. The flexible sealing strip 223 is deformed due to the squeezing with the upper surface of the conveyor belt body 4, which improves the fit between the bottom of the flexible sealing strip 223 and the top of the conveyor belt body 4, thereby realizing the sealing of the top of the conveyor belt body 4 from the outside.

[0025] Example 3: Please refer to Figure 1-9 On the basis of the first and second embodiments, the present invention provides a technical solution: the flexible sealing roller 23 includes a roller frame 231, one side of the roller frame 231 is rotatably connected to the other side of the seal mounting frame 222, the front cross-section of the roller frame 231 is a double cone, and a flexible sleeve 232 is sleeved on the surface of the roller frame 231. The material of the flexible sleeve 232 is elastic rubber. The flexible sealing roller 23 fills the space outside the sealing part of the conveyor belt through the deformation of the elastic material, thereby reducing the probability of loosening at the sealing part and improving the sealing performance of the conveyor belt; The air intake component 3 includes a blower 31, one side of which is fixedly connected to an electric motor, and the electric motor is electrically connected to an external power distribution system through a wire, the bottom of the blower 31 is connected to the circular through hole at the top of the sealing slide box 21, the top of the inner wall of the sealing slide box 21 is connected to a flexible ventilation pipe 32, and the bottom of the flexible ventilation pipe 32 is connected to the circular blind hole at the top of the slide seat 221. The high-pressure air blown in by the air intake component 3 forms a relatively thin air flow layer between the surface of the sealing strip and the surface of the conveyor belt. The high-pressure air discharged to the outside is used to reduce the probability of external impurities entering the inside of the conveyor belt through the gaps that may exist at the top of the conveyor belt, thereby further improving the sealing effect and thereby enhancing the conveying effect of the conveyor belt.

[0026] When in use, while the upper surface of the conveyor belt body 4 in the second embodiment is pressed and fitted with the bottom of the flexible sealing strip 223, the flexible sealing roller 23 is squeezed with the sealing part of the top of the conveyor belt body 4, and the top of the sealing part of the conveyor belt body 4 squeezes the surface of the flexible sleeve 232, and the flexible sleeve 232 is elastically deformed to fill the gap between the flexible sleeve 232 and the top of the sealing part of the conveyor belt body 4. While the conveyor belt body 4 slides backward, the flexible sealing roller 23 rolls to seal the sealing part of the conveyor belt body 4 below it in real time, thereby assisting in sealing the sealing part of the conveyor belt body 4 during the closed transportation stage; After the air intake assembly 3 is started, the blower 31 is powered on to work and air is sucked in from the outside. While the conveyor belt body 4 slides, the outside air is sucked into the device assembly under the action of the blower 31. After being sucked in and accelerated by the blower 31, the air enters the sealed ventilation slide 22 through the flexible ventilation pipe 32 and is blown into the bottom of the flexible sealing strip 223 through the hole structure connected to the inside of the sealed ventilation slide 22, slightly lifting the bottom of the flexible sealing strip 223, thereby reducing the friction between the bottom of the flexible sealing strip 223 and the top surface of the conveyor belt body 4 without preventing the flexible sealing strip 223 from blocking larger impurities, reducing the wear on the surface of the conveyor belt body 4, and flowing outward through the small gap at the bottom to form a relatively thin air cushion. The part of the air cushion that blows outward blows away impurities near the flexible sealing strip 223 and prevents external impurities from moving into the flexible sealing strip 223.
