[0010] Figure 1 It is a structural schematic diagram of the utility model.

[0011] Figure 2 yes Figure 1 Magnified view of part A in FIG. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0013] A dry-drawing machine drum maze structure that prevents soap powder from entering the cooling water system, such as Figure 1 and Figure 2 As shown, it includes a frame 1, a drawing reel 2, a water jacket 3, a water jacket bottom plate 4, a water jacket sealing ring 5 and a water tray 6;

[0014] The water pan 6 is relatively fixed to the frame 1, and a water return chamber 6.3 is provided in the water pan 6. The drawing reel 2 is relatively rotatable with the water pan 6, and the drawing reel 2 can rotate around its axis. A water jacket bottom plate 4 is provided in the drawing reel 2, and the water jacket bottom plate 4 is relatively fixed to the water pan 6. A water jacket 3 is fixed on the upper surface of the water jacket bottom plate 4, and a water inlet 3.1 is provided on the water jacket 3. A cooling chamber 7 is formed between the outer circle of the water jacket 3 and the inner circle of the drawing reel 2. A sealing ring installation groove is provided on the outer circle of the water jacket bottom plate 4, and a water jacket sealing ring 5 is installed in the sealing ring installation groove. A water return port 4.1 is provided on the water jacket bottom plate 4; the water inlet 3.1 is connected to the cooling chamber 7, and the internal space of the water jacket 3 is connected to the water return chamber 6.3 through the water return port 4.1;

[0015] During drawing, the metal wire 10 is evenly wound on the outer cylindrical surface of the drawing reel 2. The rotation of the drawing reel 2 drives the metal wire 10 to move. After the metal wire 10 is drawn, the temperature rises and work hardening occurs. At the same time, the drawing reel 2 also generates heat. Therefore, it is necessary to connect cooling water to the cooling chamber 7 through the water inlet pipe and the water inlet 3.1 to cool the drawing reel 2. The water that has undergone heat exchange overflows from the upper edge of the water jacket 3 and enters the return water chamber 6.3 through the return water port 4.1, and is then discharged through the outlet pipe.

[0016] Since the metal wire 10 entering the drawing reel 2 is lubricated with soap powder, the soap powder will be brought to the drawing reel 2. Since the drawing reel annular groove 2.1 and the drawing reel annular protrusion 2.2 are provided on the drawing reel 2, and the water tray annular groove 6.1 and the water tray annular protrusion 6.2 are provided on the water tray 6, the water tray annular protrusion 6.2 is embedded in the corresponding drawing reel annular groove 2.1, and the water tray annular protrusion 6.2 and the drawing reel annular groove 2.1 are in a clearance fit, the drawing reel annular protrusion 2.2 is embedded in the corresponding water tray annular groove 6.1, and the drawing reel annular protrusion 2.2 and the water tray annular groove 6.1 are in a clearance fit, the water tray annular protrusion 6.2, the drawing reel annular groove 2.1, the water tray annular groove 6.1 and the drawing reel annular protrusion 2.2 cooperate to form a labyrinth structure, one end of the labyrinth structure is connected to the space outside the drawing reel 2, and the other end of the labyrinth structure is connected to the return water chamber 6.3. The labyrinth structure can prevent soap powder from entering the water return chamber 6 . 3 of the water tray 6 .

[0017] In addition, since a mounting plate 8 is fixed on the frame 1 corresponding to the outer side of the drawing reel 2, a dust suction port 8.1 is provided on the mounting plate 8 corresponding to the winding position of the metal wire. If necessary, a dust removal interface flange 9 is fixed on the mounting plate 8, and the factory dust removal equipment can be connected through the dust removal interface flange 9, which effectively reduces the problem of soap powder diffusion and improves the on-site working environment.

[0018] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
