Description
Technical Field
[0001] The utility model relates to the field of cable processing, in particular to a cable constant temperature drying device. Background Art
[0002] During the cable processing, in order to cool the cable after the sheath is extruded, most of the cables are immersed in a water tank after the extruder head to reduce the cable temperature and solidify the sheath material. Therefore, there are many water droplets on the surface of the cable after it comes out of the water tank. In order to prevent the water from damaging the spark machine, all the moisture on the cable must be removed to ensure that the cable is dry before it can be stored.
[0003] However, the current drying measures on the market often involve sending the cables into a drying box and operating at a temperature of around 70° for seven days to dry out the moisture on the cables. The drying box's processing method is mostly to directly use electric heating wires to heat the box. The long-term high temperature environment will evaporate the moisture, which will cause the temperature near the electric heating wire in the drying box to be higher, resulting in uneven temperature in the drying box, affecting the drying effect.

The hot air unit 311 is fixed to one side of the drying box 1 and is connected to the drying box 1 through a connecting pipe 312. The connecting pipe 312 is arranged near the bottom of the drying box 1 at one end thereof. The connecting pipe 312 is provided with a plurality of air outlets at the other end thereof. A nozzle 32 is fixed to the air outlet. The nozzle 32 is used to increase the flow rate of the hot air. The temperature detection device 4 is used to detect the temperature conditions at different locations within the drying box 1. The hot air unit 311 provides hot air to the drying box 1, so that the hot air exchanges heat with the low-temperature air within the drying box 1, forming a circulating air flow, which is conducive to the overall temperature consistency within the drying box 1 and reduces the situation where the temperature of some areas is higher than that of other areas. The provision of the nozzle 32 increases the flow rate of the hot air and accelerates the drying rate of the cable. The temperature detection device 4 can also monitor the temperature conditions at different locations within the drying box 1 in real time, thereby better controlling and adjusting the drying temperature and ensuring the drying effect and product quality.
[0036] Reference Figure 1-Figure 5 The temperature detection device 4 includes multiple first temperature sensors 41 and a blower 42 with an air inlet and an air outlet. The multiple first temperature sensors 41 are fixed at different positions inside the drying box 1. The air outlet of the blower 42 is directly connected to the interior of the drying box 1. When the multiple first temperature sensors 41 detect that the temperature exceeds the set temperature or when the drying operation is completed, the blower 42 is used to blow cold air into the drying box 1. When the temperature inside the drying box 1 exceeds the set temperature, the blower 42 blows cold air into the drying box 1 to lower the temperature inside the drying box 1, so that the temperature inside the drying box 1 can be maintained at the set temperature. When the operation is completed, the blower 42 also blows cold air into the drying box 1 to lower the temperature inside the drying box 1, making it easier for operators to enter the drying box 1 and transfer the dried cables.
[0037] Reference Figure 1-Figure 5 The drying box 1 includes an outer shell 11, a metal liner 12 fixed in the outer shell 11, and an insulation layer 13 fixed between the outer shell 11 and the metal liner 12.

The insulation body 1322 is made of aerogel foamed cement, and the structural reinforcement plate 131 is made of a plate with a glass fiber mesh. The through-holes opened on the through-hole plate 1321 are honeycomb holes. The honeycomb mesh plate has good anti-bending ability, which can greatly improve the toughness and strength of the insulation through-hole plate 1321, and thus improve the toughness and strength of the entire structural insulation layer 13. At the same time, the aerogel foamed cement and the plate with the glass fiber mesh are relatively light, which can ensure the working effect of the insulation layer 13 and reduce the load of the drying box 1 itself.
[0039] Reference Figure 1-Figure 5 The door panel 2 is welded from steel plates, and a handle 14 is fixed to the outside of the drying box 1. The door panel 2 is hinged to the drying box 1, and the handle 14 is used to facilitate the operator to rotate the door panel 2 to open or close the door panel 2. The door panels of drying boxes on the market are often formed of cast iron in one piece, which is heavy. The door panel 2 welded from steel plates reduces the weight and facilitates the operator to open and close the door panel 2. The door panel 2 has multiple layers of steel plates along its thickness, and a thermal insulation cavity 22 is formed between adjacent layers of steel plates. The multiple layers of steel plates are designed to form the thermal insulation cavity 22 within the door panel 2, forming a sealed air layer within the thermal insulation cavity 22. This air layer can reduce the loss of cold air and hot air, thereby providing thermal insulation.
[0040] Reference Figure 1-Figure 5 The device also includes a locking mechanism 5, which is used to lock the door panel 2 and the drying box 1. The locking mechanism 5 includes a locking cylinder 51 and a push switch 52. A socket 53 is provided at the top of the door panel 2, perpendicular to the ground. The locking cylinder 51 is fixed to the top surface of the drying box 1, with its telescopic rod facing vertically toward the socket 53. The push switch 52 is used to control whether the telescopic rod of the locking cylinder 51 is extended. The push switch 52 is located on the side wall of the drying box 1. When the door panel 2 is fully closed, the push switch 52 is fully pressed, and the telescopic rod of the locking cylinder 51 extends and inserts into the socket 53 to complete the locking. This ensures safe operation of the equipment.
[0041] Reference Figure 1-Figure 5The drying oven 1 also includes a safety mechanism 6, which includes a second temperature sensor 61. This second temperature sensor 61 is connected to the locking cylinder 51. When the second temperature sensor 61 detects a temperature exceeding a set temperature, the telescopic rod of the locking cylinder 51 remains extended. When the temperature inside the drying oven 1 exceeds the set temperature of the second temperature sensor 61, the locking cylinder 51 locks the door panel 2, preventing the operator from opening the door panel 2, thereby ensuring the operator's personal safety. Example 2:
[0042] Reference Figure 6 The difference between Example 2 and Example 1 is that a slide groove 7 is provided at the bottom end of the drying box 1, and the door panel 2 slides in the slide groove 7. The slide groove 7 is arranged parallel to the width direction of the drying box 1. The handle 14 is used to move the door panel 2 left and right.

Two adjacent heat-resistant steel blocks 21 are separated from each other by a certain distance, and a groove 15 is provided on the side of the drying box 1 to match the heat-resistant steel blocks 21 at normal temperature. The heat-resistant steel blocks 21 are separated from each other to form expansion gaps, leaving room for deformation, thereby ensuring that the door panel 2 is not easily deformed at high temperatures, and after being inserted into the groove 15, the heat expansion during the drying process makes the heat-resistant steel block 21 fit the groove 15 more closely, thereby increasing the sealing between the door panel 2 and the drying box 1.
[0043] Reference Figure 6 The topmost piece of the heat-resistant steel block 21 is provided with a socket 53, and the push switch 52 is located on the inner wall of the groove 15. When the heat-resistant steel block 21 is fully inserted into the groove 15, the push switch 52 is fully pressed, and the telescopic rod of the locking cylinder 51 extends and inserts into the socket 53 to complete the locking, ensuring the safe operation of the equipment.
