DETAILED DESCRIPTION

[0031] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the utility model, but it is not intended to limit the scope of protection of the claims attached to the utility model.

[0032] like Figures 1 to 3 The molding module fixing device of the plastic corrugated pipe molding machine shown in the figure comprises: a bearing seat 21 for fixing the molding module 1, a connecting locking device is arranged between the bearing seat 21 and the molding module 1; the connecting locking device comprises a positioning pin 22, a rivet 23, a clamping block 24 and a connecting bolt 25. Figures 4 to 6 As shown, the surfaces where the bearing seat 21 contacts the forming module 1 are respectively the bearing seat fixed side surface 210 and the module fixed side surface, a positioning pin 22 is fixed on the bearing seat fixed side surface 210, a mounting hole for the positioning pin 22 is provided on the bearing seat fixed side surface 210, a positioning pin hole matching with the positioning pin 22 is provided on the module fixed side surface, the bearing seat 21 is provided with a rivet mounting groove 211 and a first clamping groove 212, one end of the rivet 23 is fixedly connected to the forming module 1, the other end of the rivet 23 is provided with a second clamping groove 231 and is installed in the rivet mounting groove 211, one end of the clamping block 24 is clamped in the first clamping groove 212, and the other end is clamped in the second clamping groove 231, and the clamping block 24 is fixedly connected to the bearing seat 21 by a connecting bolt 25.

[0033] In some embodiments, it is preferred that the surface where one end of the clamping block 24 fits against the first clamping groove 212 is an inclined surface, and the surface where the other end of the clamping block 24 fits against the second clamping groove 231 is an inclined surface.

[0034] like Figure 7 and Figure 8 As shown, a through hole 241 is provided in the middle of the clamping block 24 for the connection bolt 25 to pass through, a bolt hole 213 is provided on the bearing seat 21, and the connection bolt 25 passes through the through hole 241 and is threadedly connected with the bolt hole 213. The left end of the clamping block 24 is provided with a first wedge-shaped portion 242, and the right end is provided with a second wedge-shaped portion 243, and the through hole 241 is provided at the middle connecting portion between the first wedge-shaped portion 242 and the second wedge-shaped portion 243.

[0035] When the connecting bolt 25 is tightened downward, the clamping block 24 is pressed downward. In addition, one end of the clamping block 24 is in contact with the first clamping groove 212 and the other end of the clamping block 24 is in contact with the second clamping groove 231. The further the clamping block 24 moves downward, the more tightly the two ends of the clamping block 24 can clamp and fix the rivet 23 and the bearing seat 21, and the connection is reliable.

[0036] During assembly, the connecting bolt 25 needs to be screwed downward to ensure that the clamping block 24 clamps and fixes the rivet 23 and the bearing seat 21. During disassembly, the module can be separated from the module fixing device by only loosening the connecting bolt 25 upward, so that the disassembly and assembly speed is fast, the customer operation is convenient, and the wear is relatively small.

[0037] In some embodiments, to facilitate processing, such as Fig. 9 As shown, the second clamping groove 231 of the rivet 23 is set as an annular groove. The connection end of the rivet 23 and the forming module 1 is provided with a thread, and the rivet 23 is threadedly connected to the forming module 1. Since the size of the rivet 23 is relatively large (generally a non-standard part), it is not easy to remove it from the forming module 1 with an existing wrench, so an auxiliary installation threaded hole 232 is opened on the end face of the rivet 23 away from the forming module 1, and the auxiliary installation threaded hole 232 is used to install a hexagon socket bolt. A hexagonal bolt is set in the auxiliary installation threaded hole 232, and the bolt head of the hexagon socket bolt is used as the force application point of the wrench during disassembly and assembly.

[0038] like Figure 1 As shown, the molding module fixing device is arranged on the annular track, and the annular track includes an upper base plate 31 and a lower base plate 32. The upper base plate 31 is provided with an upper guide groove 311, and the lower base plate 32 is provided with a lower guide groove 321. The lower part of the bearing seat 21 is fixedly connected with a transmission gear block 28, the top of the bearing seat 21 is provided with an upper cam bearing follower 26, and the bottom of the bearing seat 21 is provided with a lower cam bearing follower 27. The upper cam bearing follower 26 can roll in the upper guide groove 311, and the lower cam bearing follower 27 can roll in the lower guide groove 321. The power device driving gear meshes with the transmission gear block 28 for transmission, thereby driving the molding module 1 to run along the upper guide groove 311 and the lower guide groove 321 of the annular track.

[0039] In order to facilitate processing and reduce processing costs, the bearing seat 21 and the transmission gear block 28 are manufactured separately, that is, the bearing seat 21 and the transmission gear block 28 are connected and fixed by fixing pins and bolts.

[0040] The molding module fixing device of the plastic corrugated pipe molding machine of the utility model can fix or separate the module and the module fixing device by only screwing the connecting bolts when installing or disassembling the module, so the disassembly and assembly speed is fast, the customer operation is convenient, and the wear is relatively small.

[0041] The present invention is not limited to the above embodiments, and all improvements made based on the concept, principle, structure and method of the present invention are within the protection scope of the present invention.
