A cleaning roller brush 20 is rotatably connected to the bottom of the first supporting frame 19 near the second movable plate 17, and a cleaning box 21 is provided on one side of the cleaning roller brush 20. A first heating block 22 is fixedly connected to the bottom of the second supporting frame near the first movable plate 16. There are four slide grooves. The connecting block 9 is located between the slide grooves, the supporting frame 19 is located on both sides of the connecting block 9, and the first heating block 22 is located above the cleaning roller brush 20. A high temperature resistance detection component is also provided on the support plate 3 for performing high temperature resistance detection on the heated packaging material.

[0032] First, the packaging material is fixed on the fixed shaft 5 and the winding shaft 6, and the first motor is started to transmit the packaging material, and the second motor 8 is driven to drive the first gear 12 clockwise. As the first gear 12 rotates clockwise, the second gear 13 and the third gear 14 meshing with the left and right sides of the first gear 12 can drive the correspondingly connected first movable plate 16 and the second movable plate 17 to perform opposite swinging activities, so that the fixed column 18 moves in the movable groove, and the first support frame 19 moves downward in the slide groove, and the cleaning roller brush 20 moves downward to fit the outer surface of the packaging material. The second support frame 19 drives the first heating block 22 to move upward. When the cleaning roller brush 20 rolls with the movement of the packaging material, the outer surface of the packaging material is cleaned. At the same time, the cleaning plate 25 rotates with the cleaning roller brush 20. Due to the push of the cleaning plate 25, the cleaning plate 25 can be tightly attached to the outer side of the cleaning roller brush 20 under the cooperation of the spring 24 connected on the left side, so that the cleaning plate 25 can scrape the cleaning roller brush 20, and the dust is sucked away by the vacuum cleaner 26, so as to prevent the cleaning plate 25 from letting the dust scraped by the cleaning roller brush 20 fall onto the packaging material again, so that the outer surface of the packaging material remains clean.

[0033] Embodiment 2: Compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that Figure 3-4 As shown, a groove is provided on one side of the support plate 3, the rear side of the second fixed block 11 is located inside the groove, the two ends of the connecting block 9 are respectively fixedly connected to the first fixed block 7 and the second fixed block 11, and movable openings are provided on both sides of the connecting block 9. One end of the first movable plate 16 and the second movable plate 17 pass through the movable openings and extend out of the connecting block 9, and the first movable plate 16 and the second movable plate 17 are respectively movably connected to the two movable openings.

[0034] The groove facilitates fixing the second fixed block 11, and the moving opening facilitates the first moving plate 16 and the second moving plate 17 to swing, ensuring that the first moving plate 16 and the second moving plate 17 on both sides can swing stably, so that the first moving plate 16 and the second moving plate 17 drive the first support frame 19 and the second support frame to move, and the cleaning roller brush 20 and the first heating block 22 move up and down, so as to keep the packaging materials clean and facilitate the high temperature resistance detection of the packaging materials.

[0035] like Figure 2-3 As shown, the first gear 12, the second gear 13 and the third gear 14 are located inside the connecting block 9, the first gear 12, the second gear 13 and the third gear 14 are arranged in a triangle, the fixing column 18 is located on both sides of the rotating shaft 10, and one end of the fixing column 18 away from the second gear 13 and the third gear 14 is rotatably connected to the outer surface of one side of the second fixed block 11.

[0036] The electric rotating shaft 10 is rotated by the second motor 8, so that the first gear 12 drives the second gear 13 and the third gear 14 to rotate. The second gear 13 and the third gear 14 are fixed by the fixing column 18, so that the second gear 13 and the third gear 14 drive the first movable plate 16 and the second movable plate 17 to move stably. Since the first gear 12, the second gear 13 and the third gear 14 are arranged in a triangle, when the second gear 13 and the third gear 14 rotate, the first movable plate 16 and the second movable plate 17 move in opposite directions, thereby realizing stable opposite rotation transmission activities.

[0037] like Figure 3 As shown, a through hole is opened on the front side of the second fixed block 11, a fixing groove is opened on the right side of the second fixed block 11, one side of the second support frame close to the first movable plate 16 extends through the through hole to the inside of the fixing groove, and an adjustment device is provided on one side of the second support frame.

[0038] The fixing groove and the through hole facilitate one end of the second support frame to pass through the through hole to connect with the adjusting device, and the second support frame drives the first heating block 22 to move up and down, so that the adjusting device can adjust the distance from the packaging material, so that the adjusting device can be close to or away from the outer surface of the packaging material, thereby facilitating the heating treatment of the outer surface of the packaging material after cleaning.

[0039] like Figure 4-7 As shown, a support plate 23 is fixedly connected to the inside of the cleaning box 21, a connecting spring 24 is fixedly connected to the top of the support plate 23, a cleaning plate 25 is fixedly connected to one end of the connecting spring 24, one side of the cleaning plate 25 is in contact with the cleaning roller brush 20, a vacuum cleaner 26 is fixedly installed between the connecting blocks 9 and inside the cleaning box 21, and the cleaning box 21 is fixedly installed to one side of the first support frame 19.

[0040] The spring 24 and the cleaning plate 25 are fixedly connected by the support plate 23, and the cleaning plate 25 is in contact with the cleaning roller brush 20. When the cleaning roller brush 20 rolls, the cleaning plate 25 cleans the cleaning roller brush 20 and scrapes off the dust on the cleaning roller brush 20. The cleaning plate 25 can be pulled back by the spring 24 connected on the left side and tightly attached to the outer side of the cleaning roller brush 20. Then, the cleaning plate 25 can scrape the outer side of the cleaning roller brush 20 to scrape off and disperse the dust, thereby avoiding the adhesion of thick dust to the outer side of the cleaning roller brush 20, which reduces the cleaning effect. The dust scraped by the cleaning plate 25 can be quickly adsorbed, exported and collected when a vacuum cleaner is installed inside the connection box to avoid the dust from floating around.

[0041] Embodiment 3: Compared with Embodiment 1 and Embodiment 2, the difference between this embodiment is that Figure 4 , Figure 8As shown, the adjusting device includes a first rack 27, the top of the first rack 27 is fixedly connected to one end of the second support frame, one side of the first rack 27 is meshed with a rotating gear 28, the middle of the rotating gear 28 is fixedly connected to a connecting rod, both sides of the connecting rod are rotatably connected to the second fixed block 11, one side of the rotating gear 28 is meshed with a second gear 13, the bottom end of the second gear 13 is fixedly connected to a second heating block 30, the second heating block 30 is located at the top of the placement block 2, the top of the second heating block 30 is fixedly connected to a telescopic rod 31, and the bottom of the telescopic rod 31 is connected to the bottom of the placement block 2 The inner wall is fixedly connected, one side of the second heating block 30 is fixedly connected to the bottom end of the second rack 29, the second rack 29 is divided into two parts, the position close to the second heating block 30 is one part, and the rest of the position is one part, a buffer limit rod 32 is movably inserted between the two parts of the second rack 29, one end of the buffer limit rod 32 is fixedly connected to the bottom of one part of the second rack 29, the other end of the buffer limit rod 32 is movably inserted between the other part of the second rack 29, and the bottom is T-shaped, and a buffer limit spring 33 is sleeved on the surface of the buffer limit rod 32.

[0042] The first heating block 22 is driven downward by the second support frame, so that the first rack 27 moves downward, and the rotating gear 28 rotates, so that the second rack 29 moves upward, which is convenient for driving the second heating block 30 to move upward, and the telescopic rod 31 is extended to fit the second heating block 30 with the first heating block 22 and the outer surface of the packaging material, so as to facilitate heating testing on both sides of the packaging material, and to improve the effect of the high temperature resistance test of the packaging material. In addition, by dividing the second rack 29 into two parts, in the process of the second rack 29 driving the second heating block 30 to move, there is a buffer space when the second heating block 30 contacts the packaging material, thereby avoiding problems such as equipment jamming due to the spacing between teeth when the structure is driven by gear transmission.

[0043] Embodiment 4: The present invention also provides a method for using the above-mentioned packaging material high temperature resistance performance testing device, the method comprising the following steps:

At the same time, the second support frame drives the first heating block 22 to move upward.

[0045] Step 2: Then, when the cleaning roller brush 20 rolls with the movement of the packaging material, the outer surface of the packaging material is cleaned. At the same time, the cleaning plate 25 rotates with the cleaning roller brush 20. Due to the push of the cleaning plate 25, the cleaning plate 25 can be pulled back by the spring 24 connected on the left side and tightly attached to the outer side of the cleaning roller brush 20. Then, the cleaning plate 25 can scrape the cleaning roller brush 20, and the dust is sucked away by the vacuum cleaner 26, so that the outer surface of the packaging material remains clean.

[0046] Step three: After cleaning, start the second motor 8 to make the rotating shaft 10 rotate counterclockwise, so that the second gear 13 and the third gear 14 drive the first movable plate 16 and the second movable plate 17 to move, so that the second movable plate 17 on the right drives the first support frame 19 to move upward, so that the cleaning roller brush 20 and the cleaning box 21 move upward along the slide groove, and the first movable plate 16 drives the second support frame and the first heating block 22 on the left to move downward and close to the outer surface of the packaging material.

[0047] Step 4: Finally, when the first heating block 22 moves downward, it drives the first rack 27 to move downward, and the rotating gear 28 rotates, so that the second rack 29 moves upward, driving the second heating block 30 to move upward, and the telescopic rod 31 extends, so that the first heating block 22 and the second heating block 30 are attached to the outer surface of the packaging material.

[0048] Working principle: When in use, the packaging material is fixed on the fixed shaft 5 and the winding shaft 6, the first motor is started to transmit the packaging material, and the second motor 8 is driven to drive the first gear 12 clockwise. As the first gear 12 rotates clockwise, the second gear 13 and the third gear 14 meshing with the left and right sides of the first gear 12 can drive the correspondingly connected first moving plate 16 and the second moving plate 17 to perform opposite swinging activities, so that the fixed column 18 moves in the moving groove, the first support frame 19 moves downward in the slide groove, and the cleaning roller brush 20 moves downward. The cleaning roller 20 is moved to fit with the outer surface of the packaging material, and the second support frame drives the first heating block 22 to move upward. When the cleaning roller brush 20 rolls with the movement of the packaging material, the outer surface of the packaging material is cleaned. At the same time, the cleaning plate 25 rotates with the cleaning roller brush 20, so that the cleaning plate 25 is in close contact with the outer side of the cleaning roller brush 20, and the cleaning roller brush 20 is scraped to scrape off the dust on the cleaning roller brush 20, and the dust is sucked away by the vacuum cleaner 26, so as to prevent the cleaning plate 25 from letting the dust scraped by the cleaning roller brush 20 fall onto the packaging material again, so that the outer surface of the packaging material remains clean.
