[0051] Example 2:

[0052] Please refer to Figure 11 and Figure 13As shown, the air pipe 4 comprises a fixed pipe 401 and a rotating pipe 402; the outer wall top end of the rotating pipe 402 is rotatably connected to the outer wall bottom end of the fixed pipe 401; the outer side wall of the rotating pipe 402 is fixedly connected with a bevel gear eight 56; the outer wall bottom end of the rotating pipe 402 is provided with an air casing 57; the outer wall bottom end of the air casing 57 is provided with a group of air outlet heads 58, and the group of air outlet heads 58 are arranged in an inclined manner; the outer wall top end of the heating box 2 is rotatably connected with a rotating rod eight 59; the outer side walls of the rotating rod eight 59 and the reciprocating rod eight 45 are both fixedly connected with a chain wheel nine 60, and a pair of chain wheels nine 60 are connected through a chain nine 61; the outer wall one end of the rotating rod eight 59 is fixedly connected with a bevel gear nine 62, and the bevel gear nine 62 is meshed with the bevel gear eight 56; when the reciprocating rod eight 45 rotates, the reciprocating rod eight 45 drives the rotating rod eight 59 to rotate through the chain wheel nine 60 and the chain nine 61, the rotating rod eight 59 drives the bevel gear nine 62 to rotate, and because the bevel gear nine 62 is meshed with the bevel gear eight 56, the bevel gear nine 62 drives the rotating pipe 402 to rotate through the bevel gear eight 56, the rotating pipe 402 drives the air casing 57 and the air outlet head 58 to rotate, and when the steam is output from the group of air outlet heads 58, the steam is dispersed to a wider range through the rotating force, so that the steam can be more uniformly dispersed into the heating box 2, the temperature difference in the heating box 2 is reduced, the cross-linking efficiency of the photovoltaic cable is improved, and the energy consumption is reduced.

[0053] In use, the photovoltaic cable is placed into the placing shell 29 at the inlet 6, and the photovoltaic cable passes through a group of rotating shells 25, an annular shell 24, an auxiliary seat 21, a rotating roller one 8 and a pair of rotating rollers two 9, so that the photovoltaic cable is sequentially placed at the outer surface top end of the rotating roller one 8 and the rotating roller two 9, and then is taken out from the placing shell 29 at the outlet 7, and the cable is clamped by a pair of arc-shaped plates 26 in the rotating shell 25, at this time, the steam is delivered into the heating box 2 from the air pipe 4 by the heating device 3, the rotating shaft 11 is driven to rotate by the motor 10, the rotating shaft 11 drives the rotating rod one 12 to rotate through the chain wheel one 14 and the chain one 15, and drives the rotating rod two 13 to rotate through the chain wheel two 16 and the chain two 17, the rotating rod one 12 and the rotating rod two 13 drive the pair of rotating rollers two 9 to rotate, and the rotating shaft 11 drives the rotating roller one 8 to rotate, when the photovoltaic cable is heated and cross-linked, the photovoltaic cable moves while being heated and cross-linked, so that each part of the photovoltaic cable periodically approaches or moves away from the heat source, a dynamic heat balance is formed, the local temperature gradient is prevented from being too large, each part of the photovoltaic cable is in different positions in turn, the local temperature difference is reduced, the photovoltaic cable is uniformly heated, the energy waste caused by local overheating is reduced, the additional energy consumption caused by the uneven temperature and the micro defects of the insulation layer of the photovoltaic cable caused by the uneven temperature are reduced, and the material quality is not easy to deteriorate.

[0054] When the photovoltaic cable heating crosslinking is completed, the rotation of the rotating roller 8 and the pair of rotating rollers 9 makes the photovoltaic cable go out of the placing shell 29 at the outlet 7 and then be transported to other process equipment for other process.

[0055] When the rotating shaft 11, the rotating rod 12 and the rotating rod 13 rotate, a set of gear wheels 18 are driven to rotate. Since a set of gear wheels 23 are respectively engaged with the set of gear wheels 18, the set of gear wheels 18 drive the set of gear wheels 23 to rotate, thereby driving a set of reciprocating rods 20 to rotate, and the set of reciprocating rods 20 drive a set of auxiliary seats 21 to reciprocate. The photovoltaic cable is first divided into several strands, and the several strands of the photovoltaic cable are respectively placed in a set of placing through slots 22. When the auxiliary seat 21 reciprocates, it drives the photovoltaic cable to move, so that the photovoltaic cable moves laterally and vertically while being heated and crosslinked. Thus, each part of the photovoltaic cable can be more uniformly contacted with heat, thereby further reducing the local temperature difference, avoiding energy waste, and making the photovoltaic cable more easily crosslinked, thereby speeding up the crosslinking efficiency of the photovoltaic cable.

[0056] Since the photovoltaic cable is clamped by the pair of arc-shaped plates 26 when it is placed on the auxiliary seat 21, the photovoltaic cable is limited when it is crosslinked, thereby being less likely to be scattered, and the photovoltaic cable is more convenient to be collected after being heated and crosslinked.

[0057] When the auxiliary seat 21 reciprocates, the auxiliary seat 21 drives the annular shell 24 and the rotating shell 25 to reciprocate. Since a plurality of rotating shells 25 are respectively engaged with a set of gear wheels 27, and the set of gear wheels 27 are respectively engaged with a set of racks 28, when the gear wheels 27 move, the gear wheels 27 rotate through the racks 28, thereby driving the rotating shell 25 to rotate. The rotation of the rotating shell 25 drives the arc-shaped plate 26 to rotate, and the arc-shaped plate 26 drives the photovoltaic cable to rotate. The photovoltaic cable moves laterally, vertically and rotates, and the photovoltaic cable rotates around its own axis. This ensures that the contact time of each point on the surface with the heat source is consistent, avoids local overheating or underheating, further reduces the temperature difference of each part of the photovoltaic cable, and forms a three-dimensional dynamic heating field through movement and rotation. This completely eliminates the "shadow area" and "hot spot area" in static heating, makes the photovoltaic cable three-dimensional dynamic heat balance, thereby making the heat more quickly penetrate into the photovoltaic cable, reducing the overall heating and crosslinking time, and further improving the crosslinking uniformity of the photovoltaic cable.

[0058] When the photovoltaic cable reciprocates with the auxiliary seat 21, the photovoltaic cable drives the placing shell 29 to move, so that the placing shell 29 moves with the movement of the photovoltaic cable. Thus, the photovoltaic cable is less likely to be stuck when it moves, ensuring the normal operation of the device and reducing the probability of failure of the device.

[0059] When the rotating shaft 11 rotates, the rotating shaft 11 drives the reciprocating rod two 32 to rotate through the sprocket three 35 and the chain three 36, so that the reciprocating rod two 32 drives the reciprocating plate 33 to reciprocate, and the reciprocating plate 33 drives a set of rotating rods 37 and gear fives 39 to reciprocate. Because a set of gear fives 39 are meshed with a set of racks five 40, and the rack five 40 is in a fixed and stationary state, when the gear five 39 moves, it rotates through the rack five 40, thereby driving the rotating rod 37 to rotate, so that the rotating rod 37 drives the fan blade one 38 to rotate, and the fan blade one 38 blows heat to the photovoltaic cable being heated and crosslinked, so that the heating and crosslinking efficiency of the photovoltaic cable is better. Moreover, the rotation of the fan blade one 38 cooperates with the rotation and movement of the photovoltaic cable, so that each part of the photovoltaic cable can be more uniformly heated and crosslinked. Furthermore, because the reciprocating plate 33 matches the auxiliary seat 21, when the auxiliary seat 21 moves, the reciprocating plate 33 also moves, so that the auxiliary seat 21 and the reciprocating plate 33 keep synchronous operation, thereby making the rotating of the fan blade one 38 always blow heat to the photovoltaic cable.

[0060] When the reciprocating rod two 32 rotates, the reciprocating rod two 32 drives the reciprocating rod three 41 to rotate through the sprocket five 42 and the chain five 43, so that the reciprocating rod three 41 drives the connecting rod 44 to reciprocate, and the connecting rod 44 drives a pair of placement shells 29 to reciprocate, thereby making the placement shell 29 keep synchronous operation with the auxiliary seat 21. When the photovoltaic cable moves vertically, the placement shell 29 keeps synchronous with it, thereby making the two ends of the photovoltaic cable be in a relatively accurate state, so that the photovoltaic cable is not easy to bend or be pressed together when heated and crosslinked, and the heating and crosslinking efficiency is better.

[0061] When the rotating shaft 11 rotates, the rotating shaft 11 drives the reciprocating rod eight 45 to rotate through the sprocket eight 46 and the chain eight 47, so that the reciprocating rod eight 45 drives the reciprocating block 48 to reciprocate, and the reciprocating block 48 drives the annular plate 50 to move. The annular plate 50 drives the annular rack 54 to move, because the rack six 55 is meshed with the annular rack 54, and the rack six 55 is in a fixed state. When the annular rack 54 moves, it rotates through the rack six 55. Because the annular rack 54 is meshed with a set of gear sixes 52, when the annular rack 54 rotates, it drives a set of gear sixes 52 to rotate, thereby driving a set of circular rods 51 and a plurality of fan blades two 53 to rotate, so that a plurality of fan blades two 53 blow and heat around the photovoltaic cable, thereby further improving the heating and crosslinking efficiency and effect of the photovoltaic cable, and further reducing the temperature difference of each part of the photovoltaic cable.

[0062] When the reciprocating rod eight 45 rotates, the reciprocating rod eight 45 drives the rotating rod eight 59 to rotate through the sprocket nine 60 and the chain nine 61, the rotating rod eight 59 drives the bevel gear nine 62 to rotate, because the bevel gear nine 62 and the bevel gear eight 56 are meshed with each other, the bevel gear nine 62 drives the rotating pipe 402 to rotate through the bevel gear eight 56, the rotating pipe 402 drives the gas shell 57 and the gas outlet head 58 to rotate, when the steam is output from a group of gas outlet heads 58, the steam is dispersed to a wider range through the rotating force, so that the steam can be more evenly dispersed into the heating box 2, the temperature difference in the heating box 2 is reduced, so that the cross-linking efficiency of the photovoltaic cable is improved while the energy consumption is reduced.
