Description

Technical Field

[0001] This utility model belongs to the field of thin film production technology, specifically a winding mechanism for producing thin films with low oxygen and moisture permeability and high barrier properties. Background Technology

[0002] High-barrier films are made by extruding a material with strong gas barrier properties and a polyolefin with strong heat-sealing and moisture barrier properties simultaneously. They are multi-layered films.

[0003] Currently, some existing winding mechanisms for producing low-oxygen-permeability, moisture-permeable, and high-barrier films use a single-end support method for the winding shaft. This method makes it easy for personnel to remove the wound film from the surface of the winding shaft after winding. However, because the other end of the winding shaft lacks support, when winding relatively heavy films, one end of the winding shaft may undergo slight deformation due to the weight. This can cause the low-oxygen-permeability, moisture-permeable, and high-barrier film roll to vibrate due to slight eccentric rotation, resulting in a decrease in winding accuracy and relative inconvenience in use. Therefore, we propose a winding mechanism for producing low-oxygen-permeability, moisture-permeable, and high-barrier films to solve or improve the above problems. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a winding mechanism for producing films with low oxygen and moisture permeability and high barrier properties, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a winding mechanism for producing low oxygen permeability, moisture permeability, and high barrier properties thin films. It includes a base plate, a second support plate fixed to the top of the base plate, a third support plate inserted inside the second support plate, a first limiting plate rotatably mounted on the top of the third support plate via a rotating shaft, a limiting ring fixed to the bottom of the first limiting plate, a first spring fixed inside the third support plate, a second limiting plate fixed to the top of the first spring, a limiting post fixed to the surface of the second limiting plate, a support frame fixed to the surface of the second support plate, an extension rod inserted inside the support frame, and a limiting component disposed inside the third support plate, which can restrict the position of the first limiting plate.

[0007] Furthermore, the limiting assembly includes a limiting rod inserted inside the third support plate, a fourth limiting plate fixed to the surface of the limiting rod, and a third spring sleeved on the surface of the limiting rod.

[0008] Furthermore, a push rod is inserted into the top of the third support plate, a third limiting plate is fixed to the bottom of the push rod, and a second spring is fixed to the bottom of the third limiting plate.

[0009] Furthermore, a first support plate is fixed to the top of the base plate, and a drive motor is fixed to the surface of the first support plate.

[0010] Furthermore, a winding shaft is fixed to the top of the output shaft of the drive motor, and a film roll with low oxygen permeability, moisture permeability, and high barrier properties is sleeved on the surface of the winding shaft.

[0011] Furthermore, a limiting block is fixed to the surface of the third support plate, and the limiting block is located inside the second support plate and is slidably connected to the second support plate.

[0012] Compared with the prior art, this utility model has the following advantages: By setting a second support plate, a third support plate, and a first limiting plate, after the low oxygen permeability, moisture permeability, and high barrier performance film is wound off the surface of the winding shaft, the third support plate can be pulled to move to the bottom of one end of the winding shaft and contact the surface of the winding shaft, thereby supporting the other end of the winding shaft. At the same time, by rotating the first limiting plate to the top of one end of the winding shaft, the surface of the first limiting plate can contact the surface of the winding shaft, thereby restricting one end of the winding shaft and preventing the other end from shaking when the winding shaft rotates. This avoids the problem of reduced winding accuracy caused by slight eccentric rotation of the low oxygen permeability, moisture permeability, and high barrier performance film roll on the surface of the winding shaft. It is relatively convenient to use. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-6As shown, this utility model is a winding mechanism for producing a low-oxygen-permeable, moisture-permeable, and high-barrier film. It includes a base plate 1, a first support plate 2 fixed to the top of the base plate 1, a drive motor 3 fixed to the surface of the first support plate 2, and a winding shaft 4 fixed to the top of the output shaft of the drive motor 3. The drive motor 3 can drive the winding shaft 4 fixed to the top of the output shaft to rotate. A roll of low-oxygen-permeable, moisture-permeable, and high-barrier film is sleeved on the surface of the winding shaft 4. When the winding shaft 4 rotates, it drives the roll of low-oxygen-permeable, moisture-permeable, and high-barrier film to rotate. A second support plate 6 is fixed to the top of the base plate 1, and a third support plate 7 is inserted inside the second support plate 6. A limit block is fixed to the surface of the third support plate 7. The limit block is located inside the second support plate 6 and slidably connected to the second support plate 6. Two sets of limiting blocks are symmetrically fixed to the surface of the third support plate 7 to restrict the position of the third support plate 7 and prevent it from detaching from the interior of the second support plate 6. A push rod 14 is inserted into the top of the third support plate 7, and two sets of push rods 14 are symmetrically inserted inside the third support plate 7. A third limiting plate 15 is fixed to the bottom of the push rod 14, and the number of third limiting plates 15 is the same as the number of push rods 14. The third limiting plates 15 restrict the position of the push rods 14 to prevent them from detaching from the interior of the third support plate 7. A second spring 13 is fixed to the bottom of the third limiting plate 15, with one end fixed to the bottom of the third limiting plate 15 and the other end fixed to the inner surface of the third support plate 7. When the push rod 14 moves... This will cause the fixed third limiting plate 15 to move. When the third limiting plate 15 moves, it will compress the second spring 13, causing the second spring 13 to deform. When there is no external interference, the second spring 13 will push the third limiting plate 15 to move, causing the third limiting plate 15 to drive the push rod 14 to move. The first limiting plate 5, which is mounted on the top of the third support plate 7, is rotated through the pivot. The top of the push rod 14 contacts the surface of the first limiting plate 5. The limiting ring 19 is fixed to the bottom of the first limiting plate 5 and inserted into the interior of the third support plate 7. The first spring 9 is fixed inside the third support plate 7. There are two sets of first springs 9 symmetrically fixed inside the third support plate 7. The second limiting plate 10 is fixed to the top of the first spring 9, and one end of the first spring 9 is fixed to the second limiting plate. The second limiting plate 10 has one end fixed to the surface of the first limiting plate 10, and the other end is fixed to the inner surface of the third support plate 7. When the second limiting plate 10 moves, it will compress the first spring 9, causing the first spring 9 to deform. When there is no external force interference, the first spring 9 will push the second limiting plate 10 to move. The limiting post 11 is fixed to the surface of the second limiting plate 10. Two sets of limiting posts 11 are symmetrically fixed to the surface of the second limiting plate 10. When the limiting post 11 moves, it will drive the fixed second limiting plate 10 to move. One end of the limiting post 11 is inserted into the interior of the second support plate 6. The support frame 8 is fixed to the surface of the second support plate 6. The support frame 8 is located on one side of the limiting post 11. The extension rod 12 is inserted into the interior of the support frame 8. Two sets of extension rods 12 are symmetrically inserted into the interior of the support frame 8. The surface of the extension rod 12 is fixed with a limiting plate.The limiting plate restricts the position of the extension rod 12, preventing it from detaching from the support frame 8. One end of the extension rod 12 is inserted into the second support plate 6 and contacts the surface of the limiting post 11. The limiting component is located inside the third support plate 7 and restricts the position of the first limiting plate 5.

[0023] The limiting assembly includes a limiting rod 18 inserted inside the third support plate 7, one end of which is inserted inside a limiting ring 19. The limiting rod 18 and the limiting ring 19 restrict the position of the first limiting plate 5, preventing it from rotating. A fourth limiting plate 17 is fixed to the surface of the limiting rod 18, restricting its position and preventing it from detaching from the third support plate 7. A third spring 16 is sleeved on the surface of the limiting rod 18, one end of which contacts the surface of the fourth limiting plate 17, and the other end contacts the inner surface of the third support plate 7. When the limiting rod 18 moves, it moves the fixed fourth limiting plate 17, which in turn compresses the third spring 16, causing it to deform. When there is no external interference, the third spring 16 will push the fourth limiting plate 17 to move, causing the fourth limiting plate 17 to drive the limiting rod 18 to move. After the limiting rod 18 moves and one end of the limiting rod 18 disengages from the inside of the limiting ring 19, the second spring 13 can push the third limiting plate 15 to move, causing the third limiting plate 15 to drive the push rod 14 to move and push one end of the first limiting plate 5 to move. This allows the first limiting plate 5 to rotate around one side of the pivot at a certain angle, causing the first limiting plate 5 to drive the limiting ring 19 to move a certain distance out of the inside of the third support plate 7. This avoids the third spring 16 pushing the limiting rod 18 back into the inside of the limiting ring 19 through the fourth limiting plate 17 when the person releases the limiting rod 18. It also eliminates the need to occupy the person's hands when opening the first limiting plate 5, improving the convenience of operation.

[0024] Working principle: When it is necessary to support the other end of the winding shaft 4, the third support plate 7 is pulled to move it closer to the winding shaft 4 and to the bottom of one end of the winding shaft 4, so that the surface of the third support plate 7 contacts the surface of the winding shaft 4, allowing the third support plate 7 to support the other end of the winding shaft 4. At the same time, when the third support plate 7 moves, it will drive the internally installed first spring 9, second limiting plate 10 and limiting post 11 to move. When the limiting post 11 moves to one side of the extension rod 12, the limiting post 11 will insert into the interior of the third support plate 7, thereby limiting the position of the third support plate 7. To prevent the third support plate 7 from moving, the limiting post 11 will contact the surface of the extension rod 12 and push the extension rod 12 to move. At this time, by rotating the first limiting plate 5 to the top of one end of the winding shaft 4, the surface of the first limiting plate 5 will contact the surface of the winding shaft 4. Thus, the first limiting plate 5 restricts one end of the winding shaft 4, preventing the other end from shaking when the winding shaft 4 rotates. This avoids the problem of reduced winding accuracy caused by slight eccentric rotation of the low oxygen permeability, moisture permeability, and high barrier film roll on the surface of the winding shaft 4. It is relatively convenient to use. At the same time, the rotation of the first limiting plate 5 will drive the bottom fixed The limiting ring 19 rotates, causing it to rotate and insert into the third support plate 7. At this time, releasing the limiting rod 18 allows the third spring 16 to push the fourth limiting plate 17 to move, which in turn moves the limiting rod 18, inserting one end of the limiting rod 18 into the limiting ring 19. This, along with the limiting rod 18 and the limiting ring 19, restricts the position of the first limiting plate 5, preventing it from rotating or wobbling when the winding shaft 4 rotates. When it is necessary to remove the wound low-oxygen-permeable, moisture-permeable, high-barrier film roll from the surface of the winding shaft 4, pulling the limiting rod 18 will allow the limiting rod 18 to rotate. One end of 8 disengages from the inside of the limiting ring 19. At this time, the first limiting plate 5 can be rotated to open around one side of the pivot. After the first limiting plate 5 is opened, the extension rod 12 can be pressed to push the limiting post 11 to move, thereby moving the limiting post 11 into the inside of the third support plate 7. When one end of the limiting post 11 disengages from the inside of the second support plate 6, the third support plate 7 will move to one side of the second support plate 6 by its own weight, thereby moving the third support plate 7 to the bottom side of the winding shaft 4. This makes it convenient for personnel to remove the low oxygen permeability, moisture permeability, and high barrier performance film roll from the surface of the winding shaft 4 after winding, making it relatively convenient to use.

[0025] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
