Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cooling water tank for an extruder. Background Art

[0002] The cooling water tank of the extruder is one of the key equipment in the cable production process. Its main function is to efficiently cool and shape the cable after it has been melted at high temperature by the extrusion die. A circulating cooling water system is installed inside the cooling water tank. Driven by a water pump, the cooling water forms a continuous flow in the tank to ensure full contact with the surface of the high-temperature extruded cable, achieving rapid and uniform cooling.

[0003] However, the cooling water troughs currently on the market are very long due to the cooling time requirements, which in turn lengthens the length of the entire cable production line, that is, the floor space of the cable production line. The function of the cooling water trough is to cool and shape, so it is impossible to reduce the distance by winding. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a cooling water tank for an extruder, which solves the technical problem that the existing cooling water tank is too long.

[0005] According to an embodiment of the utility model, an extruder cooling water tank includes a cooling water tank and a cooling wheel assembly arranged in the cooling water tank;

[0006] The cooling wheel group includes a cooling wheel, which is arranged in an arc shape and surrounds the cooling water tank near the bottom. The arc opening of the arc-shaped cooling wheel faces the top of the cooling water tank. Openings are provided on both sides of the cooling water tank near the top, and a guide wheel group is provided between the openings on both sides and the cooling wheel near the other opening.

[0007] The technical principle of the utility model is as follows: the cable extruded by the extruder enters from an opening on one side and tilts downward along a guide wheel group. The distance of this section of the guide wheel group is shorter than half the length of a traditional cooling water tank. At this time, the cable temperature has been reduced to a certain extent, that is, the initial shaping has been completed; then it is wound along the arc shape formed by the cooling wheel. Because the initial cooling has been completed, the cable will not be deformed, so it can be wound with little force; finally, it passes through the opening on the other side along the guide wheel group.

[0008] Compared with the prior art, the utility model has the following beneficial effects: by cooperating with the cooling wheel group and the guide wheel group, the forward path of the cable is changed into an arc shape, that is, by increasing the depth of the cooling water trough, the length of the cooling water trough is shortened, which solves the technical problem of the existing cooling water trough being too long and effectively reduces the floor space occupied by the cooling water trough.

[0009] Furthermore, the guide wheel group is composed of guide wheels evenly distributed along an inclined line, and the inclined line formed by the guide wheels is tangent to the arc formed by the cooling wheel.

[0010] Furthermore, active wire feeding devices and traction devices are respectively provided on the outer sides of the openings on both sides.

[0011] Furthermore, the active wire feeding device includes an active roller and a passive roller arranged on the upper side of the active roller, the active roller is transmission-connected to a driving motor, and a cooling water box is provided outside the active roller and the passive roller.

[0012] By adding an auxiliary guiding force, the cable can be prevented from being pulled and deformed when it just enters the cooling water tank.

[0013] Furthermore, one side of the cooling water box is fixed to the cooling water tank and is directly connected to the cooling water tank.

[0014] Furthermore, a water inlet interface is provided at the bottom of the cooling water tank, and a water outlet interface is provided at the lower side of the opening of the cooling water tank, and the water inlet interface and the water outlet interface are respectively provided with a stop valve.

[0015] Because the depth of the cooling water tank becomes deeper, the temperature of the water in the cooling water tank will be stratified. Due to the density relationship, the water temperature is lower near the bottom, while the water temperature is higher on the surface. Therefore, a water outlet is set at the top to quickly drain the water with the highest temperature, thereby improving the working efficiency of the water circulation system.

[0016] Furthermore, the cooling water tank is provided with a temperature sensing switch at a horizontal height position close to the water outlet interface, and the temperature sensing switch controls two on-off valves.

[0017] Furthermore, a fan is provided at the lower side of the cooling water tank, and the blowing direction of the fan is toward the cooling water tank.

[0018] Through air cooling, the temperature in the cooling water tank is taken away from bottom to top to assist cooling; it is used in environments with higher temperatures, such as in summer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1

[0027] like Figure 1-2 The extruder cooling water tank shown includes a cooling water tank 10 and a cooling wheel assembly disposed in the cooling water tank 10;

[0028] The specific cooling wheel group includes a cooling wheel 20, which is surrounded in an arc shape near the bottom of the cooling water tank 10. The arc opening 11 of the arc-shaped cooling wheel 20 faces the top of the cooling water tank 10. Openings 11 are provided on both sides of the cooling water tank 10 near the top. Guide wheel groups are provided between the openings 11 on both sides and the cooling wheel 20 near the opening 11 on the other side, that is, the cooling and shaping is completed by passing the cable through the opening 11, the guide wheel group, the cooling wheel group, the guide wheel group and the opening 11 in sequence.

[0029] like Figure 1-2 As shown, the guide wheel group is composed of guide wheels 30 evenly distributed along an inclined line. The inclined line formed by the guide wheels 30 is tangent to the arc formed by the cooling wheel 20, so that the cable transitions from the guide wheel 30 to the cooling wheel 20 more smoothly and is not easily deformed.

[0030] like Figure 1 As shown, the cooling water tank 10 is provided with a water inlet interface 12 at the bottom, and the cooling water tank 10 is provided with a water outlet interface 13 at the lower side of the opening 11. The water inlet interface 12 and the water outlet interface 13 are respectively provided with a stop valve 41. Specifically, the cooling water tank 10 is provided with a temperature sensing switch 40 at a horizontal height near the water outlet interface 13. The temperature sensing switch 40 controls the two stop valves 41. The specific control is shown in FIG. Figure 3 In the circuit diagram shown, the temperature sensing switch 40 adopts the KSD9700 model.

[0031] Example 2

[0032] like Figure 4As shown, the difference between this embodiment and embodiment 1 is that an active wire feeding device 50 and a traction device 60 are respectively provided on the outer sides of the openings 11 on both sides, the traction device 60 is used for winding the formed cables, and the active wire feeding device 50 is used for assisting the easily deformed cables to enter the cooling water tank 10.

[0033] The specific active wire feeding device 50 includes an active roller 51 and a passive roller 52 arranged on the upper side of the active roller 51. The active roller 51 is transmission-connected with a driving motor for rotating the active roller 51. The rotation speed of the active roller 51 matches the extrusion speed of the extruder to ensure that the cable is not subjected to pulling force. A cooling water box 53 is provided outside the active roller 51 and the passive roller 52. One side of the cooling water box 53 is fixed to the cooling water tank 10 and is directly connected to the cooling water tank 10, and is used for preliminary cooling of the cable and cooling the active roller 51 and the passive roller 52.

[0034] Example 3

[0035] like Figure 5 As shown, the difference between this embodiment and embodiment 1-2 is that a fan 70 is provided on the lower side of the cooling water tank 10, and the blowing direction of the fan 70 is toward the cooling water tank 10, which plays a role in assisting the cooling of the cooling water tank 10, and the blowing from bottom to top can effectively bring heat to the top of the cooling water tank 10.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
