DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following is a non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and their drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0025] Please refer to Figures 1-3 , the utility model provides a technical solution: A cooling device for aluminum alloy cable production, including a box body 1, a cavity 2 is opened in the box body 1, and two groups of rotatable conveying rollers 3 are arranged along the transverse direction on the inner walls of both sides of the cavity 2, and the two groups of conveying rollers 3 are symmetrically arranged with the center line of the cavity 2 as the symmetry axis.

[0026] On both inner walls of the cavity 2 and horizontally disposed between two sets of conveying rollers 3 is a lower support plate 4, the top end of the lower support plate 4 is lower than the bottom end of the conveying rollers 3, and the distance therebetween does not exceed the radius of the conveying rollers 3.

[0027] Above the lower support plate 4 is provided an upper support plate 5, the upper support plate 5 is fixedly connected to the inner wall of the cavity 2, and a cooling layer 6 is formed between the lower support plate 4 and the upper support plate 5. Both the lower support plate 4 and the upper support plate 5 are V-shaped symmetric structures, the axis of symmetry coincides with the midline of the cavity 2, the overall opening is upward and the bottom is a gentle transition of a curved and straight shape.

[0028] On the upper support plate 5 are provided several groups of arc-shaped grooves 7, and several groups of partition plates 8 are arranged at intervals along the axial direction of the conveying rollers 3 in the cooling layer 6. Each group of partition plates 8 extends horizontally along the cooling layer 6, and the multiple groups of partition plates 8 divide the cooling layer 6 into several groups of cooling channels 9.

[0029] Corresponding to the cooling channels 9 on the conveying rollers 3 are provided several groups of annular grooves 10, used to place the cable being conveyed in the annular grooves 10 to limit the cable and prevent the cable from slipping axially along the conveying rollers 3.

[0030] Rotatably disposed axially at the position of the arc-shaped grooves 7 on the inner wall of the cooling channel 9 is a guide roller 11, the guide roller 11 is parallel to the axis of the conveying roller 3, facilitating the conveying of the cable and reducing the frictional damage of the cable in the cooling channel 9.

[0031] There is a certain distance between the upper ends of both sides of the upper part of the lower support plate 4 and the inner walls of both sides of the cavity 2. Both upper ends of the upper part of the lower support plate 4 are fixedly connected with drainage plates 12, the side of the drainage plates 12 away from the lower support plate 4 is inclined downward, and the drainage plates 12 and the lower support plate 4 form an M-shaped structure (refer to Figure 1 )

[0032] Horizontally disposed at the upper end position of the drainage plate 12 on the inner wall of the cavity 2 is a connecting plate 14, and a drainage port for the cooling layer 6 is formed between the connecting plate 14 and the drainage plate 12.

[0033] Horizontally slidably connected to the lower side of the connecting plate 14 is a sliding plate 15, fixedly connected to the upper side of the connecting plate 14 is an electric telescopic rod 16, the output end of the electric telescopic rod 16 is fixedly connected to the sliding plate 15, and the horizontal sliding of the sliding plate 15 is controlled by the electric telescopic rod 16 to open and close the drainage port of the cooling layer 6.

[0034] Fixedly connected between the lower ends of the two groups of drainage plates 12 is a fixing plate 17, and a water storage cavity 18 is formed among the connecting plate 14, the sliding plate 15, the drainage plates 12 and the fixing plate 17 and the inner wall of the cavity 2. The cross-section of the water storage cavity 18 is a concave shape with an upward opening.

[0035] On one side of the drainage plate 12 facing away from the water storage cavity 18, a cooling plate 13 is provided for cooling the water drained from the cooling layer 6.

[0036] A water supply component is connected to the bottom side of the lower support plate 4, and the input end of the water supply component is connected to the water storage cavity 18.

[0037] The water supply component includes multiple groups of water supply pipes. Each group of water supply pipes 19 is correspondingly connected to a group of cooling channels 9, and a one-way electric control valve 23 is provided on the water supply pipe 19.

[0038] The input ends of multiple groups of water supply pipes 19 are commonly connected to a main pipeline 20. A water pump 21 is provided on the main pipeline 20. The water pump 21 is fixedly connected to the fixing plate 17, and the input end pipeline of the water pump 21 is connected to the water storage cavity 18.

[0039] A water temperature sensor 22 is provided on the lower side of the lower support plate 4 corresponding to each group of cooling channels 9 for detecting the water temperature in the cooling channels 9.

[0040] One side of the inner wall of the water storage cavity 18 is connected to a water replenishing pipe 24 for replenishing the water lost after cooling the cable into the water storage cavity 18.

[0041] In this embodiment, the cable extruded by the extruder is manually pulled to one side of the conveying roller 3 and placed in one of the annular grooves 10, and then enters the corresponding cooling channel 9. The cable extends out from the other side along the cooling channel 9 and is pulled into the annular groove 10 of the corresponding other conveying roller 3 on the other side. After passing through the annular groove 10 of the other conveying roller 3, the cable continues to be pulled outwards, dried by the cable dryer, and then fixed on the winding machine for winding.

[0042] During the cooling process of the cable, as time goes by, the water temperature in the cooling channel 9 gradually rises, so that at the same conveying speed of the cable, the water temperature in the cooling channel 9 cannot completely cool the cable.

[0043] Set the water temperature warning value in the cooling channel 9 through the water temperature sensor 22, denoted as A, that is, when the water temperature in the cooling channel 9 is not greater than A, the cable can be completely cooled.

[0044] When the water temperature in the cooling channel 9 is not higher than A, the electric telescopic rod 16 is in the extended state, that is, the sliding plate 15 is in contact with the lower support plate 4, forming a seal for the water storage cavity 18, which is beneficial for the cooling plate 13 to cool the water in the cooling cavity at a constant temperature and reduces the operating power of the cooling plate 13.

[0045] When the water temperature in the cooling channel 9 is higher than A, start the water pump 21, open the one-way electric control valve 23 corresponding to the cooling channel 9 to replace the water in the cooling channel 9, and at the same time control the electric telescopic rod 16 to retract, so that the sliding plate 15 moves, and the upper side of the water storage cavity 18 is communicated with the cold water channel.

[0046] Since the density of hot water is lower than that of cold water, the phenomenon of hot water rising and cold water sinking occurs. Therefore, when cold water is discharged from the water supply pipe 19 into the cooling channel 9, the hot water in the cooling channel 9 is forced to be discharged into the water storage cavity 18.

[0047] Since the water level in the water storage cavity 18 is higher than the horizontal line height where the fixed plate 17 is located, and the remaining volume of the water storage cavity 18 is sufficient to accommodate the volume of water discharged from the cooling layer 6, the hot water entering the water storage cavity 18 is located in the inverted triangular cavities on both sides of the water storage cavity 18, which is convenient for the cooling plate 13 to cool the entering hot water, and at the same time prevents the hot water from mixing with the original water in the water storage cavity 18 and causing the water temperature in the water storage cavity 18 to rise.

[0048] The flow rate of water entering the cooling channel 9 in the water supply pipe 19 is controlled by a flow control valve, so as to control the total volume of water entering the cooling channel 9 to be equal to the capacity of the cooling channel 9, so that the original water in the cooling channel 9 is completely replaced.

[0049] After the replacement is completed, the electric telescopic rod 16 controls the sliding plate 15 to horizontally slide and contact the lower support plate 4 again to seal and heat-insulate the water storage cavity 18.

[0050] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0051] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
