Technical Field

[0001] This utility model relates to the field of geomembrane production equipment, and in particular to a forming roller adjustment structure for a forming machine. Background Technology

[0002] Geomembrane is a waterproof barrier material made from high-molecular polymers. It has advantages such as low specific gravity, high elongation, high adaptability to deformation, corrosion resistance, low-temperature resistance, and good frost resistance. Composite reinforced waterproof geomembrane has superior water-proofing, durability, and protective properties, and is widely used in railways, highways, sports stadiums, dams, hydraulic structures, tunnels, coastal mudflats, reclamation, environmental protection, and other projects.

[0003] Geomembranes can generally be classified according to their surface characteristics as follows: (1) smooth membrane, where both sides of the membrane are smooth planes; (2) single-sided textured membrane, where one side of the membrane is a patterned plane and the other side is a smooth plane; and (3) double-sided textured membrane, where both sides of the membrane are patterned planes.

[0004] The existing geomembrane production equipment has an insufficiently stable and reliable adjustment structure for its forming rollers, which affects the synchronization of the adjustment. Utility Model Content

[0008] As a further improvement to the above technical solution:

[0009] The reducer of the first sliding motor is located above or below the slide plate, and the reducer of the second sliding motor is located above or below the center of the forming roller.

[0010] The sliding track includes a left sliding track and a right sliding track. A left lower slide plate is provided on the left sliding track, and a right lower slide plate is provided on the right sliding track. A left reducer is connected to the bottom of the left lower slide plate, and a right reducer is connected to the bottom of the right lower slide plate. The left reducer and the right reducer are connected to a first sliding motor via a coupling. A second sliding track is provided on the left sliding track.

[0013] The upper slide rail includes a first upper slide rail, an upper slide plate is provided on the first upper slide rail, the upper slide plate has a first upper sliding motor, the upper slide plate has a second upper slide rail, the fifth bearing seat of the fifth roller is slidably provided on the second upper slide rail, the fifth bearing seat is connected to the second upper sliding motor, and the fourth bearing seat of the fourth roller is fixed on the upper slide plate.

[0014] A horizontal adjustment structure is provided on the frame corresponding to the forming roller. The horizontal adjustment structure includes an adjustment motor, an adjustment seat, and an adjustment slide rail. The adjustment motor is fixed on the adjustment seat, the adjustment seat is slidably mounted on the adjustment slide rail, the adjustment slide rail is vertically fixed on the frame, and the drive shaft of the adjustment motor is connected to the bearing seat of the forming roller.

[0018] The beneficial effects of this utility model are as follows:

[0019] The bearing seat of the forming roller of this utility model is supported from both sides by the right and left lower sliding plates and the right lower sliding plate, which distributes the weight of the forming roller to the sliding plates on both sides, and then acts on the frame from the sliding plates on both sides, ensuring the balance of the force on the sliding plates. The cooperation between the sliding plates and the slide rail has higher stability and reliability, and the adjustment stability, reliability and synchronization of the forming roller are higher.

[0020] The synchronous limiting mechanism of this utility model serves two purposes: firstly, it limits the gap between adjacent forming rollers, ensuring a minimum safe distance between them and preventing direct collision between the two forming rollers; secondly, the synchronous limiting mechanism is connected to the bearing seat of the forming roller, providing support to the bearing seat. This allows the force borne by the lower slide plate to be transferred to the frame through the bearing seat, ensuring the force balance of the lower slide plate and preventing it from becoming too small or even being pulled off due to excessive force. This ensures the stability and reliability of the fit between the lower slide plate and the lower slide rail, and guarantees the synchronicity of the forming roller adjustment.

[0044] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0045] like Figure 1 As shown, the geomembrane production setup of this utility model includes a molding machine 200, an extruder 300, and a shaping frame 400 installed on the foundation 100; the molding machine 200 is vertically and flexibly installed on the foundation 100, the extruder 300 is installed on the feeding side of the molding machine 200, and the shaping frame 400 is installed on the discharging side of the molding machine 200.

[0046] like Figure 1 , Figure 4 , Figure 5 As shown, a trench 101 is formed on the foundation 100, and several supporting brackets 102 extend inward from the trench walls on opposite sides of the trench 101. The molding machine 200 is vertically and flexibly mounted on the trench 101. Figure 1 , Figure 2 , Figure 4 As shown, a base 103 is provided on the foundation 100, and a support bracket 102 is supported on the top plate of the base 103; the molding machine 200 is connected to the base 103, and the base 103 is used to support the molding machine 200. Several support brackets 102 can enhance the support strength of the top plate of the base 103 and ensure the stability and reliability of the support.

[0047] First embodiment of molding machine 200:

[0048] like Figure 6 , Figure 7As shown, the frame 6 of the molding machine 200 is equipped with several molding rollers, including textured rollers and mirror rollers. The molding rollers are arranged vertically from bottom to top. The middle molding roller is the middle roller, the molding rollers below the middle roller are the lower rollers, and the molding rollers above the middle roller are the upper rollers. In this embodiment, the frame 6 is equipped with five molding rollers, including two patterned rollers and three smooth rollers. The first roller 1, the second roller 2, the third roller 3, the fourth roller 4, and the fifth roller 5 are arranged horizontally from bottom to top between the two side plates of the frame 6. The first roller 1 and the second roller 2 are patterned 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 diameter, while the fifth roller 5 has a smaller diameter than the other forming rollers. The two 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 drive motor 13, which drives the rollers to rotate.

[0049] 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 movably connected to the side plate of the frame 6, and the third bearing seat 10 of the third roller 3 is fixed to the side plate of the frame 6. A first limiter 25 is fixedly installed on the top side of the second bearing seat 9, a second limiter 26 is fixedly installed on the top side of the third bearing seat 10, and a third limiter 27 is fixedly installed on the top side of the fourth bearing seat 11. The first limiter 25, the second limiter 26, and the third limiter 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, ensuring the minimum safe distance between two adjacent rollers and preventing collisions between adjacent rollers that could damage the rollers.

[0050] like Figure 7 , Figure 8As shown, on the two side plates of the frame 6 of the molding machine 200, vertical first lower slide rails 14 are fixedly installed corresponding to the bearing seats of the first roller 1 and the second roller 2, respectively. A slidable lower slide plate 15 is installed on the first lower slide rail 14. The bottom of the lower slide plate 15 is connected to the reducer of the first sliding motor 16, which is located below the lower slide plate 15. The first sliding motor 16 is fixed to the frame 6 and can drive the lower slide plate 15 to move up and down along the first lower slide rail 14. The second bearing seat 9 of the second roller 2 is fixed to the lower slide plate 15. On the sliding plate 15, below the second bearing seat 9 and corresponding to the first bearing seat 8 of the first roller 1, a vertical second sliding rail 17 is provided. The first bearing seat 8 is slidably mounted on the second sliding rail 17. The bottom of the first bearing seat 8 is connected to the reducer of the second sliding motor 18. The reducer of the second sliding motor 18 is located below the center of the first roller 1. The second sliding motor 18 can drive the first bearing seat 8 to move up and down along the second sliding 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 sliding motor 16 drives the sliding 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 sliding motor 16 is located below the sliding plate 15, and the reducer of the second sliding motor 18 is located below the center of the first roller 1, making the force on the sliding plate 15 and the first bearing seat 8 more balanced, and the cooperation with the sliding rail more stable and reliable.

[0051] like Figure 8As shown, a synchronous limiting mechanism 24 is provided 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 to 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 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 synchronous limiting mechanism 24 serves two purposes: firstly, it limits the gap between the first roller 1 and the second roller 2, ensuring a minimum safe distance between them and preventing the first roller 1 from directly colliding with the second roller 2; secondly, since the first roller 1 and the second roller 2 are located at the bottom and connected to the lower slide plate 15, the lower slide plate 15 is subjected to pressure from the rollers above, in addition to the gravity of the first roller 1 and the second roller 2. The limiting rod 241 of the synchronous limiting mechanism 24 is connected to the second bearing seat 9, providing support for the second bearing seat 9. This allows the force borne by the lower slide plate 15 to be distributed to the limiting rod 241 via the second bearing seat 8 and the second sliding motor 18, which then acts on the frame 6. This ensures the force balance of the lower slide plate 15, preventing it from becoming too small or even falling off due to excessive force. It also ensures the stability and reliability of the fit between the lower slide plate 15 and the first sliding rail 14, guaranteeing the synchronicity of the adjustment of the first roller 1 and the second roller 2.

[0052] like Figure 7 , Figure 9As shown, on the two side plates of the frame 6 of the molding machine 200, vertical first upper slide rails 19 are fixedly installed corresponding to the bearing seats of the fourth roller 4 and the fifth roller 5, respectively. A slidable upper slide plate 20 is installed on the first upper slide rail 19. The top of the upper slide plate 20 is connected to the reducer of the first upper sliding motor 21, which is located above the upper slide plate 20. The first upper sliding motor 21 is fixed to the frame 6 and can drive the upper slide plate 20 to move up and down along the first upper slide rail 19. The fourth bearing seat 11 of the fourth roller 4 is fixed to the upper slide plate 20. On the upper slide plate 20, above the fourth bearing seat 11 and corresponding to the fifth roller 5, a vertical second upper slide rail 22 is provided on the fifth bearing seat 12. The fifth bearing seat 12 is slidably mounted on the second upper slide rail 22. The top of the fifth bearing seat 12 is connected to the reducer of the second upper sliding motor 23. The reducer of the second upper sliding motor 23 is located above the center of the fifth roller 5. The second upper sliding 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 sliding motor 21 drives the upper slide plate 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 sliding motor 21 is located above the upper slide plate 20, and the reducer of the second upper sliding motor 23 is located above the center of the fifth roller 5, making the force on the upper slide plate 20 and the fifth bearing seat 12 more balanced, and the cooperation with the slide rail more stable and reliable.

[0053] like Figure 6 , Figure 7 As shown, a lifting mechanism is provided between the molding machine 200 and the foundation 100. The lifting mechanism includes a lifting power device, a lifting slide 29, and a guide block 30. The lifting power device includes a lifting rod 31 and a lifting motor 32. Several lifting seats 28 are provided extending from the outer side plates of the two side plates of the frame 6 of the molding machine 200, facing the trench wall of the ground trench 101 of the foundation 100. In this embodiment, two lifting seats 28 are provided on each of the two side plates. Figures 1-2 , Figures 15-17 As shown, a vertical lifting rod 31 is fixed on a lifting base 28. The lifting rod 31 is connected to a lifting motor 32 mounted on a base 103. The lifting motor 32 drives the lifting rod 31 to rise and fall, thereby driving the forming machine 200 to rise and fall, adjusting it to the required production mode to produce the corresponding geomembrane products. Figure 4 , Figure 6 , Figure 7As shown, lifting slides 29 are provided on the sides of the two side plates of the frame 6, and dovetail grooves are formed on the lifting slides 29. Guide blocks 30 are correspondingly provided on the wall of the ground groove 101, and dovetail blocks are provided on the guide blocks 30. The dovetail blocks of the guide blocks 30 slide within the dovetail grooves of the lifting slides 29. When the molding machine 200 moves up and down, the lifting slides 29 move up and down along the guide blocks 30. In other embodiments, guide blocks 30 can also be provided on the frame 6, and lifting slides 29 can be provided on the wall of the ground groove 101. Dovetail grooves can be provided on one of the lifting slides 29 and guide blocks 30, and dovetail blocks can be provided on the other. The lifting slides 29 and guide blocks 30, through the structural cooperation of the dovetail grooves and dovetail blocks, have higher stability and reliability, making the lifting of the molding machine 200 smoother and more reliable. The molding machine 200, driven by a lifting mechanism, can operate in multiple production modes based on the set number of molding rollers, enabling the production of various product types. In each production mode, a subset of the molding rollers is used as processing rollers for the corresponding product type. For example... Figures 15 to 17 As shown, the vertical five-roll forming machine 200 of this embodiment can have three production modes: the first production mode is the double-sided textured film 500 production mode, which uses the first roll 1, the second roll 2, and the third roll 3 as processing rolls ( Figure 15 As shown); the second production mode is the single-sided textured film 600 production mode, using the second roller 2, the third roller 3, and the fourth roller 4 as processing rollers (as shown). Figure 16 As shown); the third production mode is the glossy film 700 production mode, which uses the third roller 3, the fourth roller 4, and the fifth roller 5 as processing rollers (as shown). Figure 17 (As shown in the figure); all three production modes use the third roller 3 as the processing roller.

[0054] Second embodiment of molding machine 200:

[0055] like Figures 12 to 14 As shown, in this embodiment, the bearing seat adjustment structure of the forming roller of the forming machine 200 is different from that in the first embodiment.

[0056] like Figure 12 , Figure 13As shown, on the mounting positions of the two side plates of the frame 6 of the molding machine 200, corresponding to the bearing seats of the first roller 1 and the second roller 2, vertical left lower slide rails 51 and right lower slide rails 53 are arranged facing each other on the left and right side walls of the mounting positions. A slidable left lower slide plate 52 is provided on the left lower slide rail 51, and a slidable right lower slide plate 54 is provided on the right lower slide rail 53. A second lower slide rail 17 is provided on the left lower slide plate 52. The first bearing seat 8 of the first roller 1 is slidably mounted on the second lower slide rail 17. The bottom of the first bearing seat 8 is connected to the reducer of the second sliding motor 18. One end of the second bearing seat 9 of the second roller 2 is connected to the left lower slide plate 52, and the other end is connected to the right lower slide plate 54. The bottom of the lower left slide plate 52 is connected to the left reducer 55, and the bottom of the lower right slide plate 54 is connected to the right reducer 56. The left reducer 55 and the right reducer 56 are connected to the same first sliding motor 16 via a coupling 57. The first sliding motor 16 drives the lower left slide plate 52 and the lower right slide plate 54 to move up and down synchronously, thereby driving the first roller 1 and the second roller 2 to move up and down synchronously. The second sliding motor 18 can drive the first bearing seat 8 to move up and down along the second sliding rail 17, thereby driving the first roller 1 to move up and down to adjust the pressing gap between the first roller 1 and the second roller 2. In this embodiment, the lower left and right slide plates 52 and the lower right slide plate 54 of the bearing seat of the second roller 2 provide support from both sides, distributing the weight of the second roller 2 to the slide plates on both sides, and then acting on the frame 6 from the slide plates on both sides, ensuring the balance of the force on the slide plates, and improving the stability and reliability of the cooperation between the slide plates and the rails. The adjustment stability, reliability, and synchronization of the first roller 1 and the second roller 2 are also improved. In this embodiment, a fourth limiter 58 is provided between the first bearing seat 8 and the second bearing seat 9, and the fourth limiter 58 is fixed to the bottom side of the second bearing seat 9.

[0057] like Figure 12 , Figure 14As shown, on the mounting positions of the two side plates of the frame 6 of the molding machine 200, corresponding to the bearing seats of the fourth roller 4 and the fifth roller 5, vertical upper left slide rails 59 and upper right slide rails 61 are arranged facing each other on the left and right side walls of the mounting positions. A slidable upper left slide plate 60 is mounted on the upper left slide rail 59, and a slidable upper right slide plate 62 is mounted on the upper right slide rail 61. A second upper slide rail 22 is mounted on the upper left slide plate 60, and the fifth bearing seat 12 of the fifth roller 5 is slidably mounted on the second upper slide rail 22. The top of the fifth bearing seat 12 is connected to the reducer of the second upper sliding motor 23. One end of the fourth bearing seat 11 of the fourth roller 4 is connected to the upper left slide plate 60, and the other end is connected to the upper right slide plate 62. The top of the upper left sliding plate 60 is connected to the reducer of the first upper sliding motor 21. When the first upper sliding motor 21 drives the upper left sliding plate 60 to move up and down, it drives the fourth roller 4 and the fifth roller 5 to move up and down synchronously. The second upper sliding motor 23 can drive the fifth bearing seat 12 to move up and down along the second upper sliding 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. In this embodiment, the second limiter 26 is fixedly installed on the bottom side of the fourth bearing seat 11 of the fourth roller 4.

[0058] like Figures 12 to 14 As shown, in this embodiment, horizontal adjustment structures are respectively provided on the two side plates of the frame 6 for the bearing seats of the second roller 2 and the fourth roller 4. The horizontal adjustment structures include an adjustment motor 63, an adjustment seat 64, and an adjustment slide rail 65. The adjustment motor 63 is fixed on the adjustment seat 64, which is slidably mounted on the adjustment slide rail 65. The adjustment slide rail 65 is vertically fixed on the frame 6. When the bearing seats of the second roller 2 / fourth roller 4 move up and down, the adjustment motor 63 moves synchronously up and down along the adjustment slide rail 65 via the adjustment seat 64. The drive shaft of the adjustment motor 63 is connected to the bearing seats of the second roller 2 / fourth roller 4. The adjustment motor 63 can fine-tune the horizontal position of the second roller 2 / fourth roller 4 via the drive shaft. Whether in a stopped or working state, the adjustment motor 63 can automatically adjust.

[0059] The molding machine 200 in both the first and second embodiments is a five-roll molding machine, with five molding rolls arranged vertically. The first roll 1 and the second roll 2 are patterned rolls, and the remaining rolls are smooth rolls. The patterned rolls are arranged at the bottom of the molding machine 200, resulting in more stable and higher-quality products, and more stable equipment operation. In these two embodiments, the uppermost fifth roll 5 is a metal roll, which serves as a cooling roll. In other embodiments, the fifth roll 5 can also be a silicone roll. When a silicone roll is used, the fifth roll 5 can be used as a molding roll. When the fifth roll 5 is used as a molding roll, a cooling guide roll can be fixed above the fifth roll 5 to guide the products molded by the fifth roll 5 and the fourth roll 4 outward.

[0060] The film produced by the molding machine 200 of this invention can achieve a film thickness of 0.3-3mm.

[0061] like Figure 1 , Figure 3 , Figure 10 As shown, the extruder 300 is equipped with a traveling mechanism, which includes guide wheels 37, a traveling motor 38, a gear 39, a traveling guide rail 40, and a rack 41. Several guide wheels 37 and a traveling motor 38 are respectively arranged on opposite sides of the base 36 of the extruder 300. A gear 39 is mounted on the drive shaft of the traveling motor 38. The traveling guide rail 40 is fixed to the foundation 100, and the guide wheels 37 are rotatably mounted on the traveling guide rail 40. The rack 41 is fixed to the traveling guide rail 40 and meshes with the gear 39. The traveling motor 38 can drive the gear 39 to travel on the rack 41, thereby causing the extruder 300 to move towards or away from the molding machine 200.

[0062] like Figure 10 As shown, several extrusion units 42 are mounted on the base 36 of the extruder 300. Each extrusion unit 42 is equipped with an extrusion mechanism 421. The feed end of the extrusion mechanism 421 is equipped with a feed hopper, which is connected to an extrusion motor 423 via a reducer 422. The discharge end of the extrusion mechanism 421 is sequentially connected to a screen changer 424 and a metering pump 425. The screen changer 424 is used to filter out impurities from the plasticized material, and the metering pump 425 is used to control the flow rate. The several extrusion units 42 are connected to an extrusion die 44 via a manifold assembly 43. The plasticized material from each extrusion unit 42 is collected by the manifold assembly 43 and then sent to the extrusion die 44. The extrusion die 44 is a flat die, as shown in the image. Figure 1 As shown, the extrusion die 44 is directly opposite the pressure gap of the corresponding forming roller of the molding machine 200. During operation, the extrusion die 44 extrudes plasticized material into the pressure gap of the corresponding forming roller.

[0063] like Figure 1 , Figure 11 As shown, the shaping frame 400 is hinged to the frame 6 of the forming machine 200, with the hinge point located above the intermediate roller (the third roller 3 in this embodiment). The shaping frame 400 is arranged at an angle, tilting downwards from the feed end to the discharge end. Figure 11 As shown, the feed end of the frame 45 of the shaping frame 400 is hinged to the frame 6 of the forming machine 200. A roller 48 is provided at the bottom of the discharge end of the frame 45, which can roll on the surface of the foundation 100. When the feed end of the frame 45 rises and falls with the forming machine 200, the frame 45 adjusts its position by rolling the roller 48. Several shaping rollers 46 are provided on the frame 45 for guiding the film. A cutting assembly 47 is also provided on the frame 45, which can move along the frame 45 in the feed to discharge direction to cut the film at a designated position.

[0064] In actual use, the required production mode is selected according to the type of product being produced: (1) such as Figure 15 As shown, when producing double-sided textured film 500, the forming machine 200 rises until the gap between the first roller 1 and the second roller 2 is directly opposite the extrusion die 44 of the extruder 300. The plasticized material extruded by the extruder 300 through the extrusion die 44 is extruded by the first roller 1 and the second roller 2 to form double-sided textured film 500. The double-sided textured film 500 passes through the second roller 2 and the third roller 3 in sequence, and is then sent to the next process via the shaping frame 400. (2) As Figure 16 As shown, when producing single-sided textured film 600, the forming machine 200 descends until the gap between the second roller 2 and the third roller 3 is directly opposite the extrusion die 44 of the extruder 300. The plasticized material extruded by the extruder 300 through the extrusion die 44 is extruded by the second roller 2 and the third roller 3 to form single-sided textured film 600. The single-sided textured film 600 passes through the third roller 3 and the fourth roller 4 in sequence, and is then sent to the next process via the shaping frame 400. (3) As Figure 17 As shown, when producing the glossy film 700, the forming machine 200 descends until the gap between the third roller 3 and the fourth roller 4 is directly opposite the extrusion die 44 of the extruder 300. The plasticized material extruded by the extruder 300 through the extrusion die 44 is extruded and formed into the glossy film 700 by the third roller 3 and the fourth roller 4. The glossy film 700 passes through the fourth roller 4 and the fifth roller 5 in sequence and is then sent to the next process via the shaping frame 400.

[0065] The molding machine 200 of this invention is a height-adjustable molding device. Driven by a lifting mechanism, it can switch between different production modes, enabling a single molding machine 200 to produce multiple types of products. This reduces the need for additional equipment and accessories, lowering investment costs. The molding machine 200 only requires lifting for position adjustment to switch production modes, saving the need to replace molding rollers. This not only saves workload, time, and replacement costs, but also avoids the dangers associated with changing molding rollers, preventing safety risks.

[0066] The above description is an explanation of the present utility model and not a limitation thereof. The present utility model can be modified in any form without departing from its spirit.
