DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] To describe the technical content, structural features, achieved objectives and effects of the application in detail, the technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments can also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments can be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shapes, structures and characteristics of the exemplary embodiments can be used or implemented in another exemplary embodiment.
[0018] The embodiment of the present application provides a wide-width geomembrane production line. As Figure 1 , 2 shown, the wide-width geomembrane production line 100 includes an extruder 1, a screen changer 2, a metering pump 3, an extrusion die 4, a three-roll calender 5, a thickness gauge 6, a cooling bracket 7, a tractor 8, a storage rack 9 and a winder 10, which are arranged in sequence from front to back.
[0019] The extruder 1 is used to plastify and melt the raw materials sufficiently and then transport them to the extrusion die 4. The extrusion die 4 extrudes the plastified sufficient materials in a sheet shape to form a blank of the product. The extrusion die 4 has an extrusion port for extruding the blank, and the width of the extrusion port is 8000 mm - 9000 mm, so as to realize the extrusion of wide-width products. In order to provide sufficient materials for the extrusion die 4 to meet the high-efficiency production, in the embodiment of the present application, the number of extruders 1 is two, and both extruders 1 are single-screw extruders. On the one hand, the two extruders 1 meet the requirements of the extrusion die 4 for extruding wide-width products, and on the other hand, they improve the output of the production line and achieve the production purposes of high yield and high efficiency.
[0020] As Figure 2 , 3 shown, the production line 100 includes two screen changers 2. One screen changer 2 is arranged at the discharge port of one extruder 1. The screen changer 2 is used to filter the materials output from the discharge port at the discharge port to prevent the materials that are not completely plastified from entering the extrusion die 4 and affecting the quality of the extruded products. And when too many impurities are filtered out on the screen changer 2, the screen changer 2 can be replaced in time to avoid affecting the transportation of the materials. The metering pump 3 is fluidly connected between the discharge port and the extrusion die 4 and is used to adjust the flow rate of the materials transported from the discharge port to the extrusion die 4 and transport the materials evenly, so that the products extruded by the extrusion die 4 can have uniform thickness.
[0021] As Figure 1As shown in the figure, the three-roll calender 5 includes an upper roll 51, a middle roll 52, and a lower roll 53 arranged in sequence from top to bottom. The upper roll 51, the middle roll 52, and the lower roll 53 all extend in the left-right direction and all rotate around their own axis lines. The extrusion port of the extrusion die 4 extrudes the blank between the middle roll 52 and the lower roll 53. The blank snakes around the middle roll 52 and the upper roll 51 from bottom to top, and finally is led out from the upper side of the upper roll 51 and backward out of the three-roll calender 5. The blank extruded by the extrusion die 4 is calendered to the required thickness by the three rolls of the three-roll calender 5, and the surface is pressed flat. The three-roll calender 5 is connected to a roll temperature controller 11, and the roll temperature controller 11 is used to control the roll temperature of each roll of the three-roll calender 5 to ensure the calendering and forming of the product by the three-roll calender 5.
[0022] The three-roll calender 5 is movably arranged at the rear side of the extrusion die 4 in the front-rear direction. When the extrusion die 4 needs to be maintained or the three-roll calender 5 needs to change rolls, the three-roll calender 5 moves backward to be away from the extrusion die 4, which is convenient for maintenance and roll change.
[0023] The thickness gauge 6 is arranged at the rear side of the three-roll calender 5 and is used to measure the thickness of the product led out by the three-roll calender 5, and can timely detect the product with insufficient thickness, so as to timely adjust the roll spacing of the three-roll calender 5 and the thickness of the extrusion port, thereby more accurately controlling the thickness of the product.
[0024] As Figure 1 、 2 As shown in Figure 5, an operating platform 12 is installed at the rear side of the three-roll calender 5. The operating platform 12 has a platform 121 located above the lower roll 53 and a staircase 122 for the operator to move from the ground to the platform 121. The thickness gauge 6 is installed on the platform 121, and the platform 121 supports the thickness gauge 6 so that the test port of the thickness gauge 6 is closer to the upper roll 51. The platform 121 is fixed at the rear end of the frame of the three-roll calender 5, and the staircase 122 is fixed at the rear end of the platform 121 and is located on the left and right sides of the cooling bracket 7. The staircase 122 slopes backward and downward from the rear end of the platform 121, and a plurality of rollers 123 are arranged at the bottom of the staircase 122. When the three-roll calender 5 moves in the front-rear direction, the operating platform 12 can move in the front-rear direction along with the three-roll calender 5. A fence 124 is arranged around the circumference of the platform 121 to play a protective role.
[0025] As Figure 1 、 2As shown in FIGS. 4, the cooling bracket 7 is installed between the operating table 12 and the tractor 8. The cooling bracket 7 includes a bracket 71 and a plurality of cooling rollers 72 rotatably arranged on the bracket 71. The plurality of cooling rollers 72 are spaced apart along the extending direction of the bracket 71, so that the product led out by the thickness gauge 6 is cooled during the movement on the cooling bracket 7; since the wide-width geomembrane is produced by this production line, the plurality of cooling rollers 72 are divided into left and right rows to be able to carry the geomembrane with a larger width. The front end of the bracket 71 is connected to the operating table 12, and the rear end of the bracket 71 is connected to the tractor 8. Since the operating table 12 will move back and forth along with the three-roll calender 5, the bracket 71 connected to the operating table 12 will also move back and forth. In order to avoid pulling the rear tractor 8 and facilitate the forward and backward movement of the three-roll calender 5, the cooling bracket 7 is a two-section telescopic cooling bracket. The bracket 71 includes a front bracket 711 and a rear bracket 712. The front end of the front bracket 711 is hinged to the rear end of the platform 121, and the rear end of the front bracket 711 is slidably installed on the front end of the rear bracket 712. The rear bracket 712 is supported on the ground by a support frame 714; a transition wheel 713 is rotatably arranged below the rear end of the front bracket 711, and the front end of the rear bracket 712 has a transition section 7121 for the transition wheel 713 to roll back and forth. When the three-roll calender 5 moves back and forth, the front bracket 711 moves back and forth relative to the rear bracket 712 to achieve the telescopic function and avoid moving the rear bracket 712 and the tractor 8. A baffle 715 protruding upward is arranged at the front end of the transition section 7121. The baffle 715 is used to block on the front side of the transition wheel 713 to prevent the front bracket 711 from falling off the transition section 7121 when moving forward and ensure the safety of the equipment operation.
[0026] As Figure 1 , 2 shown, a trimming device 13 and a waste edge winder 14 are arranged on the rear bracket 712. The waste edge winder 14 is arranged at the rear side of the trimming device 13. The trimming device 13 is used to trim the uneven edges of the product on the cooling bracket 7, cut off the uneven edges, make the side edges of the product flat, and the cut edges are wound by the waste edge winder 14. The trimming device 13 is arranged on the upper side of the rear bracket 712. The trimming device 13 includes a pair of cutter assemblies 131 arranged oppositely left and right on the rear bracket 712. Each cutter assembly 131 is movably arranged on the rear bracket 712 in the left-right direction, and each cutter assembly 131 can adjust its position in the left-right direction according to the width of the required product. The number of the waste edge winders 14 is two. The two waste edge winders 14 are arranged oppositely left and right on the lower side of the rear bracket 712. Each cutter assembly 131 is configured with a waste edge winder 14, and each waste edge winder 14 is used to wind the waste edges cut by the corresponding cutter assembly 131.
[0027] As Figure 1 , 6As shown, the tractor 8 is used to tow the product on the cooling bracket 7 towards the winder 10 for the winder 10 to wind the product. The tractor 8 includes an upper traction roller 81 and a lower traction roller 82 which are arranged opposite to each other up and down. The lower traction roller 82 is in transmission connection with a traction motor 83 and rotates around its own axis under the drive of the traction motor 83. The upper traction roller 81 is in transmission connection with a traction cylinder 84. The traction cylinder 84 is used to drive the upper traction roller 81 to press against and move away from the lower traction roller 82. The upper traction roller 81 presses the product onto the lower traction roller 82, and the lower traction roller 82 rotates to drive the product to move downstream through relative friction.
[0028] As Figure 1 , 7 shown, the storage rack 9 is arranged between the tractor 8 and the winder 10. The winder 10 is used to wind the product, and the storage rack 9 is used to temporarily store the product conveyed from the front side when the winder 10 changes the roll, so as to realize the online roll change of the winder 10. The storage rack 9 includes a pair of upper storage rollers 91, a lower storage roller 92 located below the pair of upper storage rollers 91, and a drive assembly 93 for driving the pair of upper storage rollers 91 to move in the up and down direction. The product snakes around the upper storage rollers 91, the lower storage roller 92 and the upper storage rollers 91 from front to back. The drive assembly 93 is configured to drive the pair of upper storage rollers 91 to move upward when the winder 10 changes the roll, so as to increase the moving path of the product on the storage rack 9 and achieve the purpose of temporarily storing the product by the storage rack 9. After the winder 10 changes the roll, the drive assembly 93 drives the pair of upper storage rollers 91 to slowly descend to release the product.
[0029] The various devices of the present application cooperate with each other and assist each other in working, and the wide-width geomembrane production line formed improves the output and production efficiency of the wide-width geomembrane, meeting the market's demand for a high-yield and high-efficiency production line.
