DETAILED DESCRIPTION

[0029] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] like Figure 1 , Figure 2 As shown, the utility model provides a multifunctional composite processing equipment for polymer smooth sheet and special-shaped sheet, and is provided with a hopper 1 and an extruder 2 in sequence along the sheet production direction, which are used to extrude the raw materials. A mold 3 is provided at the end of the extruder 2, which is used to extrude the raw materials and process them into sheets. According to different molds, the processing equipment can be used to produce different types of sheets.

[0032] In order to improve equipment utilization, increase production capacity, and meet product diversification needs, the molding mechanism, cooling mechanism, traction mechanism, etc. of the utility model are provided with a variety of implementation methods.

[0033] The forming mechanism of the utility model is used for shaping the sheet. The forming mechanism includes a movable double-roll forming machine 4 and a three-roll calender 5. The double-roll forming machine 4 is installed on the ground through a transverse slide rail 7, and the three-roll calender 5 is installed on the ground through a longitudinal slide rail 6. The longitudinal slide rail 6 is laid along the sheet production direction, and the transverse slide rail 7 is laid perpendicular to the sheet production direction. The double-roll forming machine 4 can move left and right along the transverse slide rail 7, move out or move into the sheet production direction, and the three-roll calender 5 can move forward and backward along the longitudinal slide rail 6.

[0034] When producing smooth sheets, the roll forming machine 4 is translated to one side along the transverse slide rail 7, and the three-roll calender 5 is moved forward. The sheet enters the three-roll calender 5, is shaped after passing through three rollers, and is then sent to the first cooling mechanism. When producing special-shaped sheets, due to the special shape and poor surface pressure resistance, the roll forming machine 4 is required to extrude the sheet. Therefore, the three-roll calender 5 needs to be moved backward and the roll forming machine 4 needs to be translated to the production line. The sheet first enters between the two rollers of the roll forming machine 4, and the gear shape of the rollers can be adjusted as needed. The formed sheet enters between any two adjacent rollers of the three-roll calender 5. The upper roller and the lower roller of the three-roll calender 5 are provided with a lifting mechanism to make them approach or move away from the middle roller. Since the pressure-bearing capacity of the special-shaped sheet is poor, it is necessary to widen the distance between the two rollers used on the three-roll calender 5 to allow the special-shaped sheet to pass smoothly. At this time, the rollers on the three-roll calender 5 play the role of supporting the sheet.

[0035] The formed sheet enters the cooling mechanism for cooling. The cooling mechanism of the utility model includes a first cooling frame 8 arranged at the rear of the three-roll calender 5, and a plurality of first cooling rollers 9 are arranged on the first cooling frame 8. The plurality of first cooling rollers 9 are driven by a motor and a transmission chain. A plurality of unpowered lower rollers 10 are also arranged on the first cooling frame 8. Furthermore, the cooling mechanism also includes a second cooling frame 11 arranged at the rear of the first cooling frame 8, and a plurality of horizontally arranged second cooling rollers 12 are arranged on the second cooling frame 11.

[0036] A plurality of first cooling rollers 9 are arranged in a staggered manner on the first cooling frame 8. The smooth sheet that has passed through the three-roll calender 5 passes through the first cooling rollers 9 one by one, and then is conveyed backward along the second cooling roller 12. The smooth sheet is gradually cooled during the above conveying process. A plurality of unpowered lower rollers 10 are arranged in parallel at the lower part of the first cooling frame 8, and the tops of the plurality of unpowered lower rollers 10 are on the same plane. At the same time, unpowered lower rollers 10 are also arranged on the side of the first cooling frame 8. After the special-shaped sheet passes through the three-roll calender 5, it is conveyed backward along the unpowered lower rollers 10 and the second cooling roller 12. Similarly, the special-shaped sheet is cooled during the conveying process.

[0037] Furthermore, during the conveying process, a trimming mechanism is required to trim the two sides of the sheet. The trimming mechanism of the utility model comprises a knife frame 13 and a trimming knife 14. As a preferred embodiment, the trimming knife 14 is arranged on the second cooling frame 11.

[0038] Furthermore, a first traction mechanism for pulling the sheet is provided at the rear of the cooling mechanism. The first traction mechanism of the utility model includes a first friction traction device 15 and a pair of roller traction devices 16 which are sequentially arranged along the production direction of the sheet. A friction traction roller is arranged in the first friction traction device 15, and a traction pair of rollers is arranged in the pair of roller traction device 16. After the smooth sheet passes through the first friction traction device 15, it is pulled by the pair of roller traction device 16 and then enters the gluing mechanism. In this process, the first friction traction device 15 plays a role in supporting the sheet. After the special-shaped sheet is cooled, it is pulled by the first friction traction device 15, and then passes through the pair of roller traction device 16 and enters the gluing mechanism. In this process, the pair of roller traction device plays a role in supporting the sheet.

[0039] The gluing mechanism of the utility model comprises a gluing frame 17, on which a non-woven fabric unwinding device 18, a composite pressure roller group 19 and a gluing roller pair group 20 are arranged. As shown in the embodiment shown in the figure, the non-woven fabric unwinding device 18 comprises a non-woven fabric roller shaft, and the non-woven fabric unwinding device 18 is arranged at the upper part of the gluing frame 17. The composite pressure roller group 19 is arranged at the middle part of the gluing frame 17, and the composite pressure roller group 19 is composed of three composite pressure rollers 191, and each composite pressure roller 191 is connected to a cylinder 21 to adjust the position. The gluing roller pair group 20 is arranged at the lower part of the gluing frame 17, and is composed of a pair of gluing rollers 201.

[0040] When producing smooth sheets, the smooth sheets directly enter the gluing mechanism along the roller traction device 16. Since the smooth sheets do not need to be bonded with the non-woven fabric, there is no need to apply glue, and the sheets can be directly pulled, cut and rolled. When producing smooth sheets, the cylinder 21 drives the composite pressure roller 191 located at the top to lift up, and the sheet is conveyed backwards via the other two composite pressure rollers 191. When producing special-shaped sheets, it is necessary to apply glue to the sheets and compound the non-woven fabric. The utility model is provided with a plurality of guide rollers 22 on the roller traction device 16 and the gluing frame 17. The guide rollers 22 are located at the lower part of the roller traction device 16 and the gluing frame 17, and guide the special-shaped sheets to enter the gluing mechanism from below. Preferably, a heating device can be provided on the gluing roller 201. The special-shaped sheets are coated with glue by the gluing roller group 20, and compounded with the non-woven fabric by the composite pressure roller group 19.

[0041] After the gluing mechanism, the utility model is provided with a material storage rack 23, a second traction mechanism 24, a cross-cutting mechanism and a winding mechanism.

[0042] The storage rack 23 is a foldable rack, and a plurality of storage rollers 25 are arranged in a staggered manner. The smooth sheets are wound around the storage rollers 25 one by one. Furthermore, a hoist 26 is arranged on the top of the storage rack 23. The storage rack 23 can be changed into two states of standing or lying flat by the hoist 26. When conveying special-shaped sheets, the storage rack 23 is laid flat, and the special-shaped sheets are conveyed backwards in a straight manner supported by the guide rollers at the bottom of the storage rack 23.

[0043] The cross-cutting mechanism of the utility model includes a smooth sheet cross-cutting device 27 arranged at the rear of the storage rack 23, where the smooth sheet is cross-cut, and after being pulled by the second traction mechanism 24 at the rear, it is rolled up by the rolling mechanism 28. The cross-cutting mechanism also includes a rotary knife cross-cutting device 29 arranged at the rear of the second traction mechanism 24, and after the special-shaped sheet passes through the second traction mechanism 24, it is cross-cut by the rotary knife and then rolled up.

[0044] The utility model integrates the production of different types of sheets on one production line. The shaping of different types of sheets is achieved through the coordinated use of a double-roll forming machine and a three-roll calender. The cooling of different types of sheets is achieved through the upper and lower composite structures in the first cooling mechanism. Different types of traction pressures are set through the traction mechanism to make the pressure controllable. The slitting of different types of sheets is achieved by setting two sets of cross-cutting mechanisms. The utility model achieves the purpose of multifunctional composite co-line processing of smooth sheets and special-shaped sheets.
