Description

Technical Field

[0001] The invention relates to the field of high-barrier film preparation, in particular to a device for manufacturing a high-barrier film for pharmaceutical packaging. Background Art

[0002] High barrier film is a film material with excellent gas barrier properties for pharmaceutical packaging. Its main raw materials are polyvinylidene chloride or ethylene / vinyl alcohol copolymer and other raw materials. The production method is usually to extrude the material with strong gas barrier properties with polyolefins with strong heat-sealing and moisture barrier properties at the same time to form a multi-layer film. Nowadays, high barrier films are also commonly used in pharmaceutical packaging for the packaging of moisture-absorbing and volatile drugs to ensure the stability and effectiveness of the drugs.

[0003] In the production process of high-barrier films, the resin particles are generally first extruded through an extruder, and then the multi-layer plastic raw materials are extruded and blown into bubble tubes through a bag blowing machine, and finally pressed into a film through a winding device. The winding device is generally composed of multiple rollers, and the high-barrier film is finally formed through the cooperation between the rollers. However, in display production, the rollers may wear, or position deviations may occur during long-term use. In the process of forming high-barrier films, left and right swings may be caused. In severe cases, black edges may be exposed and local sealing wrinkles may occur. Summary of the invention

[0020] 5. The present invention arranges a plurality of stabilizing cylinders below the guide roller, wherein a stabilizing cylinder with a small inner diameter is placed on a stabilizing cylinder with a large inner diameter. Stabilizing cylinders with different inner diameters can be adjusted according to the size of the high-barrier film blown out of the film blowing machine, thereby making the cylindrical film move upward better.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] like Figures 1 to 8 As shown, the present invention provides a high-barrier film manufacturing device for pharmaceutical packaging, which includes a base 1, a mounting plate 2 is symmetrically provided on the top of the base 1, an extruder 3 is provided on the outer side of one of the mounting plates 2, a film blowing machine 4 connected to the extruder 3 is provided between the two mounting plates 2, and a symmetrical frame group is provided on the opposite surface of the mounting plate 2 close to the top, and a guide groove 6 is provided inside each frame 5, and the guide groove 6 is provided to enable a steel rod 7 to slide in the guide groove 6, so that the distance between the two steel rods 7 is controlled.

[0032] A steel rod 7 is provided between the two frames 5, and a sliding shaft 8 is provided inside the steel rod 7. The sliding shaft 8 is slidably installed in the guide groove 6. Sliding plates 9 connected together are provided at both ends of the sliding shaft 8. A rotating screw 10 is provided on the side wall of the sliding plate 9 facing the mounting plate 2. The rotating screw 10 is rotatably connected to the sliding plate 9 and the mounting plate 2, and a rotating disk 11 is provided at the other end extending out of the mounting plate 2. The rotating disk 11 and the rotating screw 10 are fixedly connected. A threaded ring cooperating with the rotating screw 10 is provided in the mounting plate 2. The rotating screw 10 will realize a change in stroke during the rotation process, thereby driving the sliding plate 9 to move together.

[0033] A movable support assembly is provided between the upper and lower steel rods 7 .

[0034] The frame 5 on the same layer is symmetrically provided with scale lines 12 near the outside, and the scale lines 12 are symmetrically arranged at the upper and lower ends of the guide groove 6. A positioning block 13 is symmetrically provided on the sliding plate 9 at one end near the scale lines 12. A vertical indicator line 14 is provided on the positioning block 13. When the steel rod 7 moves, the steel rod 7 will drive the positioning block 13 to move together. There is an indicator line 14 on the positioning block 13, so that the distance moved by the steel rod 7 can be known by comparing the indicator line 14 with the scale lines 12, and the steel rods 7 on both sides can be flexibly adjusted to move the same distance, thereby avoiding the situation where the distances on both sides are inconsistent.

[0035] The movable support assembly includes a support plate 15, a lifting shaft 16, a telescopic spring 17 and a bearing rod 18. The support plate 15 is symmetrically arranged between the upper and lower steel rods 7. The back sides of the two support plates 15 are arc-shaped surfaces. The arc-shaped design can better adapt to the outer wall shape of the steel rod 7, so that the support plate 15 will not fall off when the steel rod 7 rotates. The lifting shaft 16 is symmetrically arranged on the opposite surfaces of the two support plates 15.

[0036] The lifting shafts 16 are distributed at intervals on the support plate 15, and the other ends of the two lifting shafts 16 extend into the bearing rod 18. The lifting shafts 16 are slidably set in the bearing rod 18. The telescopic spring 17 is sleeved on the lifting rod and between the support plate 15 and the bearing rod 18. The arc-shaped surface of the support plate 15 is provided with a rotating cylinder 19 distributed in an arc shape. The rotating cylinder 19 is rotatably connected to the support plate 15 and the rotating cylinder 19 is movably fitted with the outer ring wall of the steel stick 7. Under the elastic force of the telescopic spring 17, supporting force is provided for the upper and lower steel rollers, thereby ensuring that the position of the steel rollers will not change during long-term rotation, effectively avoiding position deviation, resulting in left and right swinging during the forming process of the high barrier film, and in severe cases, black edges and local sealing wrinkles will be exposed, thereby improving the effect of forming the high barrier film.

[0037] Mutually inclined rectangular plate groups 20 are symmetrically arranged below the steel rod 7. There are two rectangular plate groups 20 on the side close to the mounting plate 2. The spacing between the rectangular plate groups 20 gradually decreases as they go up. Guide rollers 21 are arranged between the rectangular plate groups 20 on the same side. The guide rollers 21 are rotatably connected to the rectangular plate groups 20. By setting the inclined guide rollers 21, compression is gradually achieved upward when coming out of the film blowing machine 4.

[0038] Limit rotating rings 22 are symmetrically provided on both sides of the rectangular plate group 20 near the bottom, and a rotating shaft 23 penetrating from the rectangular plate group 20 is provided between the two limit rotating rings 22. The circular wall of the limit rotating ring 22 has limit holes 24 distributed in a circle around the rotating pin. The positioning strips 29 can be inserted into the limit holes 24 to fix them, and finally the guide roller 21 can be kept fixed, so that the angle of the guide roller 21 remains unchanged during the process of the film being flattened from a cylindrical shape.

[0039] Limiting plates 25 are provided at both ends of the rotating shaft 23, and the rotating shaft 23 is movably connected to the inside of the limiting plates 25. A positioning pin 26 is provided on the limiting plate 25, and a positioning strip 29 passes through the limiting plate 25 and is inserted into the limiting hole 24. A positioning plate 27 fixedly connected to each other is provided on the annular wall of the limiting plate 25 and between the mounting plate 2. The provided positioning plate 27 can fix the limiting plate 25. Only by keeping the position of the limiting plate 25 unchanged can the position of the limiting rotating ring 22 be fixed.

[0040] After the positioning pins 26 are inserted into the limiting holes 24 at different positions, the limiting rotating ring 22 is fixed, so that the clamping angle between the guide rollers 21 can be adjusted according to the requirements of films of different thicknesses, thereby improving the flexibility of the device.

[0041] A stabilizing cylinder 28 is provided above the film blowing machine 4. The interior of the stabilizing cylinder 28 is hollow. Insert strips 29 are symmetrically provided on the outer ring wall of the stabilizing cylinder 28. The vertical section of the insert strip 29 is an inverted "7" shape. A fixedly connected bearing block 30 is provided on the opposite surface of the mounting plate 2. The bearing block 30 is provided with a matching hole 31. The insert strip 29 is inserted into the matching hole 31. The stabilizing cylinder 28 can be disassembled by matching the provided plug sleeve with the bearing block 30, which is simple and flexible.

[0042] There are no less than two stabilizing cylinders 28, and each stabilizing cylinder 28 has a platform 32 on the top. The platform 32 on the stabilizing cylinder 28 with a small inner diameter is placed on the top of the stabilizing cylinder 28 with a large inner diameter. When the film blowing machine 4 blows the film into cylinders of different sizes, it can adjust the size of the stabilizing cylinder 28 to better adapt to the size of the film, and also enable the film to rise better in the stabilizing cylinder 28.

[0043] Detailed usage and effects of the above embodiments:

[0044] When it is necessary to make a high-barrier film, the raw materials for making the high-barrier film are first put into the extruder 3. Under the action of the extruder 3, the raw materials will be extruded by the film head into a film-like shape and enter the film blowing machine 4. The film blowing machine 4 will blow the film into a cylindrical form and move upward. When making high-barrier films of different widths, they will be blown into cylindrical shapes of different sizes. There is a hollow stabilizing cylinder 28 on the top of the film blowing machine 4, and there is an insertion strip 29 on the annular wall of the stabilizing cylinder 28. After installation, the insertion strip 29 is inserted into the matching hole 31 in the bearing block 30 to fix the stabilizing cylinder 28. The stabilizing cylinder 28 is divided into multiple layers. The stabilizing cylinder 28 with a small inner diameter is placed on the stabilizing cylinder 28 with a large inner diameter through a platform 32. The stabilizing cylinders 28 of different levels can be installed or removed to adapt to the size of the film. The film will pass upward in the stabilizing cylinder 28.

[0045] The film is gradually compressed by the guide rollers 21 during the upward movement, and the film changes from a cylindrical shape to a waist shape. However, the film is not pressed at this time. When we need to adjust the inclination angle of the guide rollers 21, in the initial state, the positioning strips 29 are inserted into the limiting holes 24, and the positioning strips 29 are pulled out of the limiting holes 24. At this time, the limiting rotating ring 22 is rotated, and the limiting rotating ring 22 rotates around the rotating shaft 23. The limiting disk 25 is fixedly connected to the mounting plate 2 through the positioning plate 27. The position of the limiting disk 25 is different, and the limiting rotating ring will move with the rectangular plate group 20 when it rotates. After rotating to a suitable angle, the positioning pin 26 is reinserted, so that the positioning pin 26 is inserted into the limiting holes 24 at different positions, thereby keeping the position of the limiting rotating ring 22 fixed again, and realizing the angle adjustment of the guide roller 21.

[0046] After the film rises from the guide roller 21, it will enter the winding device, and the film will pass between the two steel rods 7. The two steel rods 7 will rotate, thereby driving the film to finally be made into a high-barrier film, and the high-barrier film will be driven to move outward during rotation. However, during a long period of work, if the steel rod 7 is worn, at this time, the staff can hold the rotating disk 11, and the rotating disk 11 is connected to the rotating screw 10. The other end of the rotating screw 10 is connected to the sliding plate 9. There is a threaded ring in the mounting plate 2 that cooperates with the rotating screw 10. When the rotating screw 10 rotates, it will drive the sliding plate 9 to move together. The sliding plate 9 is connected to the sliding shaft 8, and the sliding shaft 8 passes through the inside of the steel rod 7 and moves in the guide groove 6, so that the distance between the two steel rods 7 can be adjusted.

[0047] There are symmetrical scale lines 12 on the frame 5, a positioning block 13 on the sliding plate 9, and an indicator line 14 on the positioning block 13. When the steel rod 7 is moved, the position of the indicator line 14 changes synchronously, so that the two steel rods 7 can be adjusted to move the same distance according to the position of the indicator line 14 on the scale line 12.

[0048] There is a support plate 15 between the upper and lower steel rods 7. The surface of the support plate 15 close to the steel rod 7 is an arc-shaped surface. There is a rotating cylinder 19 on the arc-shaped surface. When the steel rod 7 rotates, the rotating cylinder 19 will rotate along with it. The rotating cylinder 19 is rotatably connected to the support plate 15. The arc-shaped design prevents the position of the support plate 15 from changing. There is a lifting shaft 16 and a bearing rod 18 between the two support plates 15. The telescopic spring 17 is sleeved on the lifting shaft 16 and will press against the support plate 15, so that the support plate 15 moves outward. When the support plate 15 and the other components are installed between the two steel rods 7, the steel rod 7 can be supported, thereby ensuring that the position of the steel rod 7 will not change during long-term use, thereby avoiding the subsequent high-barrier membrane on the steel rod 7. Position deviation, causing left and right swings, and in severe cases, black edges and local sealing wrinkles will be exposed.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
