DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0023] according to Figure 1-6 As shown, an integrated winding molding die for a HDPE hollow wall production line comprises a molding main disk 1, a molding sub-disk 2 is provided at the front end of the molding main disk 1, a plurality of groups of molding rollers 3 are provided between the molding sub-disk 2 and the molding main disk 1, a plurality of groups of the molding rollers 3 are rotatably connected with the molding main disk 1 and the molding sub-disk 2, a plurality of groups of the molding rollers 3 have rotating shafts passing through the molding main disk 1, a transmission gear 4 is fixedly connected to the end of the rotating shaft by a key, a transmission gear ring 5 is provided inside the transmission gear 4, the transmission gear 4 is meshed with the transmission gear ring 5, and the transmission gear ring 5 is rotatably mounted on the molding main disk 1 through a bearing.

[0024] In the above specific embodiment, the transmission gear 4 on the forming roller 3 is meshed with the transmission gear ring 5, and all the forming rollers 3 can be driven to rotate synchronously through the transmission gear ring 5, so that the power is more uniform, the transmission efficiency is improved, and then the production efficiency is improved. The various components of the winding mold are produced separately, which effectively reduces the manufacturing difficulty. After being transported to the production site, they are assembled on site, thereby reducing the production cost and transportation cost.

[0025] The present embodiment provides an integrated winding forming mold for a HDPE hollow wall production line. During assembly, first, conical bearings 8 are installed at both ends of the forming roller 3 and the driven roller 6, and then the conical bearings 8 at both ends are respectively inserted into the mounting grooves 7 of the forming main disk 1 and the forming sub-disk 2, and the connecting rod 9 is inserted into the waist-shaped hole 11. The forming sub-disk 2 is pressed toward the forming main disk 1 by the locking nut 10, so that the conical bearing 8 fits tightly with the mounting groove 7. Finally, the transmission gear 4 is installed on the rotating shaft of the forming roller 3, so that the transmission gear 4 is meshed with the transmission gear ring 5 on the forming main disk 1 to complete the assembly of the winding mold. After the assembly is completed, the winding mold is fixed to the forming machine 13, and the forming roller 3 connected to it is driven to rotate by the motor 14 on the forming machine 13. The other forming rollers 3 rotate synchronously under the action of the transmission gear ring 5 to process the winding tube. Since the various components of the winding mold are produced separately, the manufacturing difficulty is effectively reduced, and they are assembled on site after being transported to the production site, thereby reducing the production cost and transportation cost. The specific technical scheme is as follows:

[0026] Several groups of forming rollers 3 are evenly distributed along the circumferential edge of the forming main disk 1, two groups of driven rollers 6 are arranged between several groups of forming rollers 3, and the driven rollers 6 are rotatably connected to the forming main disk 1 and the forming sub-disk 2. Several groups of forming rollers 3 are provided with anti-slip patterns on their outer walls. The anti-slip patterns on the surfaces of the forming rollers 3 increase the friction between the forming rollers 3 and the inner wall of the winding tube. The forming rollers 3 and the driven rollers 6 are conical structures with a small front end and a large rear end, so that the winding tube moves forward as a whole. The diameter of the forming sub-disk 2 is smaller than the diameter of the ring formed by the forming rollers 3 and the driven rollers 6, so that the winding tube can be easily removed from the winding mold.

[0027] The forming main disk 1 and the forming sub-disk 2 are connected with the forming roller 3 and the driven roller 6 at the connection points thereof. The side walls of the mounting groove 7 are conical surfaces with a small bottom surface and a large top surface. A tapered bearing 8 is installed in the mounting groove 7. The outer circumferential surface of the tapered bearing 8 is a conical surface corresponding to the side walls of the mounting groove 7. The tapered bearing 8 can be easily placed in the mounting groove 7. The forming roller 3 and the driven roller 6 are rotatably installed on the forming main disk 1 and the forming sub-disk 2 via the tapered bearing 8.

[0028] The forming main disk 1 is equipped with a plurality of connecting rods 9, preferably six groups of connecting rods 9, which are plugged into the forming sub-disk 2. Locking nuts 10 are installed at the ends of the connecting rods 9. The locking nuts 10 are used to press the forming sub-disk 2 toward the forming main disk 1, so that the tapered bearing 8 fits tightly with the mounting groove 7. The connecting rods 9 are evenly distributed near the edge of the forming sub-disk 2 to make the clamping force more evenly distributed.

[0029] The forming sub-disk 2 is provided with a plurality of waist-shaped holes 11, the number of which is consistent with the number of connecting rods 9. The waist-shaped holes 11 are arc-shaped structures and are evenly distributed circumferentially on the forming sub-disk 2. When assembling the winding mold, an assembly margin is reserved through the waist-shaped holes 11 to facilitate the adjustment of the angle of the forming sub-disk 2 to align with the forming main disk 1.

[0030] A dustproof ring 12 is fixedly installed at the edge of the forming sub-disk 2 , and the dustproof ring 12 covers the installation groove 7 to prevent dust from entering the installation groove 7 and clogging the tapered bearing 8 .

[0031] A plurality of mounting holes 15 are provided at the edge of the forming main plate 1, and bolts are installed in the mounting holes 15. The forming main plate 1 is fixedly mounted on the forming machine 13 by bolts. A motor 14 is installed on the forming machine 13. The power output shaft of the motor 14 is connected to the rotating shaft of any group of forming rollers 3 through a coupling. The motor 14 drives the forming rollers 3 connected thereto to rotate, and the other forming rollers 3 rotate synchronously under the action of the transmission gear ring 5.

The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
