Description

Technical Field

[0001] The invention relates to the field of geomembrane production equipment, in particular to a multi-roller forming machine, a sheet film production process and a sheet film production system. Background Art

[0002] Geomembrane is a waterproof barrier material with high molecular polymer as the basic raw material, which has the advantages of small specific gravity, strong elongation, high adaptability to deformation, corrosion resistance, low temperature resistance, and good antifreeze performance. Composite reinforced waterproof geomembrane has excellent water-proof, durability, and protection, and is widely used in railways, highways, stadiums, dams, hydraulic structures, tunnels, coastal beaches, reclamation, environmental protection and other projects.

[0003] Geomembranes can generally be divided into the following categories based on their surface characteristics: (1) smooth membranes, in which both the front and back sides of the membrane are smooth surfaces; (2) single-sided textured membranes, in which one side of the membrane is a surface with a pattern and the other side is a smooth surface; and (3) double-sided textured membranes, in which both the front and back sides of the membrane are surface with a pattern.

[0004] The existing geomembrane production equipment is usually equipped with a molding machine with a single product function. It can only produce one type of product and cannot be directly used for other types of products. For example, a molding machine for producing single-sided textured membrane cannot be used to directly produce smooth membrane or double-sided textured membrane. In this case, in order to achieve the production of multiple types of products, it is often achieved through the following ways: (1) Equip different product molding machines according to different product types. In this way, it is necessary to equip multiple types of molding machines and matching sets of accessories. The equipment cost is high, the floor space is large, and the production line investment cost is high. (2) By replacing the molding rollers on the molding machine to achieve the production of different types of products, the equipment and accessories are reduced and the investment cost is reduced. In this way, the molding rollers of the molding machine need to be replaced. Since the weight of the molding rollers is very heavy, the weight of a single molding roller can reach 9 to 20 tons. Therefore, the replacement of the molding rollers is difficult, the workload is large, the time is long, and the replacement cost is high. In addition, there are dangers in the process of replacing the molding rollers. If you are not careful, it may cause harm to the workers, posing a safety risk. Summary of the invention

[0046] First embodiment of the molding machine 200: like Figure 6 , Figure 7 As shown, a plurality of forming rollers are arranged on the frame 6 of the forming machine 200, and the forming rollers include texture rollers and mirror rollers. The plurality of forming rollers are arranged vertically and arranged vertically from bottom to top; the middle forming roller of the plurality of forming rollers is the middle roller, the plurality of forming rollers below the middle roller are the lower rollers, and the plurality of forming rollers above the middle roller are the upper rollers. In this embodiment, five forming rollers are arranged on the frame 6, including two pattern rollers and three smooth rollers, and the first roller 1, the second roller 2, the third roller 3, the fourth roller 4, and the fifth roller 5 are arranged horizontally between the two side plates of the frame 6 from bottom to top, the first roller 1 and the second roller 2 are pattern rollers, and the third roller 3, the fourth roller 4, and the fifth roller 5 are smooth rollers; the central axes of the five rollers are located on the same vertical plane, the first roller 1 and the second roller 2 are the lower rollers, the third roller 3 is the middle roller, and the fourth roller 4 and the fifth roller 5 are the upper rollers. The first roller 1, the second roller 2, the third roller 3, and the fourth roller 4 have the same roller diameter, and the roller diameter of the fifth roller 5 is smaller than the roller diameters of the other forming rollers. Both ends of the five rollers are connected to the frame 6 through bearing seats, and one end of each roller is connected to an independent driving motor 13, and each roller is driven to rotate by the independent driving motor 13.

[0047] like Figures 7 to 9 As shown, the first bearing seat 8 of the first roller 1, the second bearing seat 9 of the second roller 2, the fourth bearing seat 11 of the fourth roller 4, and the fifth bearing seat 12 of the fifth roller 5 are connected to the side plate of the frame 6 in a manner that they can move up and down, and the third bearing seat 10 of the third roller 3 is fixed on the side plate of the frame 6. A first stopper 25 is fixedly arranged on the top side of the second bearing seat 9, a second stopper 26 is fixedly arranged on the top side of the third bearing seat 10, and a third stopper 27 is fixedly arranged on the top side of the fourth bearing seat 11. The first stopper 25, the second stopper 26, and the third stopper 27 respectively limit the minimum gap between the second roller 2 and the third roller 3, the minimum gap between the third roller 3 and the fourth roller 4, and the minimum gap between the fourth roller 4 and the fifth roller 5, thereby ensuring the minimum safety distance between two adjacent rollers and preventing the two adjacent rollers from colliding and damaging the rollers.

[0048] like Figure 7 , Figure 8 As shown, on the two side plates of the frame 6 of the forming machine 200, the bearing seats corresponding to the first roller 1 and the second roller 2 are respectively fixedly provided with vertical first lower rails 14, and the first lower rails 14 are provided with slidable lower slide plates 15, the bottom of the lower slide plates 15 is connected to the reducer of the first sliding motor 16, the reducer of the first sliding motor 16 is located below the lower slide plates 15, the first sliding motor 16 is fixed on the frame 6, and the first sliding motor 16 can drive the lower slide plates 15 to move up and down along the first lower rails 14. The second bearing seat 9 of the second roller 2 is fixed on the lower slide plates 15. On the lower slide plate 15, a vertical second lower rail 17 is provided on the first bearing seat 8 corresponding to the first roller 1 and located below the second bearing seat 9. The first bearing seat 8 is slidably arranged on the second lower rail 17. The bottom of the first bearing seat 8 is connected to the reducer of the second lower sliding motor 18. The reducer of the second lower sliding motor 18 is located below the center of the first roller 1. The second lower sliding motor 18 can drive the first bearing seat 8 to move up and down along the second lower rail 17, thereby driving the first roller 1 to move up and down to adjust the film pressing gap between the first roller 1 and the second roller 2. When the first lower sliding motor 16 drives the lower slide plate 15 to move up and down, it can drive the first roller 1 and the second roller 2 to move up and down synchronously to adjust the film pressing gap between the second roller 2 and the third roller 3. The reducer of the first lower sliding motor 16 is located below the lower slide plate 15, and the reducer of the second lower sliding motor 18 is located below the center of the first roller 1, so that the force of the lower slide plate 15 and the first bearing seat 8 is more balanced, and the cooperation with the slide rail is more stable and reliable.

[0049] like Figure 8As shown, a synchronous limiting mechanism 24 is arranged between the first bearing seat 8 and the second bearing seat 9. The synchronous limiting mechanism 24 includes a limiting rod 241 and a synchronous limiting lift 242. The synchronous limiting lift 242 is fixed on the top side of the first bearing seat 8. The lower end of the limiting rod 241 is connected to the synchronous limiting lift 242, and the upper end is pressed against the bottom side of the second bearing seat 9 and fixed on the second bearing seat 9; the limiting rod 241 is located below the center of the second roller 2. The function of the synchronous limiting mechanism 24 is: on the one hand, it limits the gap between the first roller 1 and the second roller 2, ensures the minimum safety distance between the first roller 1 and the second roller 2, and prevents the first roller 1 from directly colliding with the second roller 2; on the other hand, since the first roller 1 and the second roller 2 are arranged at the lower part and connected to the lower slide plate 15 at the same time, the lower slide plate 15 is subjected to the pressure transmitted from the upper roller in addition to the gravity of the first roller 1 and the second roller 2, and the lower slide plate 15 is subjected to a large force; the limiting rod 241 of the synchronous limiting mechanism 24 is connected to the second bearing seat 9, which can provide support for the second bearing seat 9, so that the force borne by the lower slide plate 15 can be distributed to the limiting rod 241 through the second bearing seat 9, and then acted on the frame 6 through the first bearing seat 8 and the second lower sliding motor 18, thereby ensuring the force balance of the lower slide plate 15, preventing the lower slide plate 15 from being too small or even pulling off the lower slide plate 15 due to excessive force, ensuring the matching stability and reliability of the lower slide plate 15 and the first lower slide rail 14, and ensuring the synchronization of the adjustment of the first roller 1 and the second roller 2.

The fourth bearing seat 11 of the fourth roller 4 is fixed on the upper slide plate 20. On the upper slide 20, a fifth bearing seat 12 located above the fourth bearing seat 11 and corresponding to the fifth roller 5 is provided with a vertical second upper slide rail 22. The fifth bearing seat 12 is slidably arranged on the second upper slide rail 22. The top of the fifth bearing seat 12 is connected to the reducer of the second upper slide motor 23. The reducer of the second upper slide motor 23 is located above the center of the fifth roller 5. The second upper slide motor 23 can drive the fifth bearing seat 12 to move up and down along the second upper slide rail 22, thereby driving the fifth roller 5 to move up and down to adjust the film pressing gap between the fourth roller 4 and the fifth roller 5. When the first upper slide motor 21 drives the upper slide 20 to move up and down, it can drive the fourth roller 4 and the fifth roller 5 to move up and down synchronously to adjust the film pressing gap between the fourth roller 4 and the third roller 3. The reducer of the first upper slide motor 21 is located above the upper slide 20, and the reducer of the second upper slide motor 23 is located above the center of the fifth roller 5, so that the forces on the upper slide 20 and the fifth bearing seat 12 are more balanced, and the cooperation with the slide rail is more stable and reliable.

Figure 1-Figure 2 , Figure 15-17 As shown, the vertical lifting rod 31 is fixed on the lifting seat 28, and the lifting rod 31 is connected to the lifting motor 32 set on the base 103. The lifting motor 32 drives the lifting rod 31 to move up and down, thereby driving the molding machine 200 to move up and down, so as to adjust to the required production mode to produce the corresponding geomembrane products. Figure 4 , Figure 6 , Figure 7As shown, a lifting slide 29 is provided on the side edges of the two side panels of the frame 6, and a dovetail groove is provided on the lifting slide 29; a guide block 30 is correspondingly provided on the groove wall of the ground groove 101, and a dovetail block is provided on the guide block 30, and the dovetail block of the guide block 30 is slid into the dovetail groove of the lifting slide 29.

The molding machine 200 can have multiple production modes according to the number of molding rollers set, and can realize the production of multiple types of products by driving the molding machine 200 up and down through the lifting mechanism. When each production mode produces the corresponding type of product, some of the molding rollers are used as processing rollers for production.
