DETAILED DESCRIPTION

[0035] The present invention providesFigures 1 to 10 An extrusion device for producing photovoltaic cables as shown, including an extrusion device 1 and a drying cylinder 2, which dries the cables passing through the coolant in the drying cylinder 2 and is used in conjunction with the extrusion device 1 to improve the production efficiency of photovoltaic cables.

[0036] The extrusion device 1 includes structures such as an extruder. In addition, cooling equipment etc. (not shown in the figure) are also provided to cooperate to form an extrusion process; the cooling equipment is located between the extrusion device 1 and the drying cylinder 2. The cooling equipment includes structures such as a cooling pool, and the coolant in the cooling pool cools the extruded cables. Both the extrusion device 1 and the cooling equipment are common existing technologies and will not be elaborated here.

[0037] Refer to Figure 2 、 Figure 3 、 Figure 4 As shown in

[0038] Refer to Figure 4 、 Figure 6 As shown in, the drying cylinder 2 is arranged on the frame. To improve the extrusion efficiency, a drying mechanism for drying the cables passing through the coolant is arranged inside the drying cylinder 2.

[0039] To improve the drying efficiency, circular grooves 4 are opened on the inner ring of the air outlet ring box 3. There are multiple circular grooves 4, and the multiple circular grooves 4 are evenly distributed around the inner ring of the air outlet ring box 3. And rubber blocks 5 are installed inside the circular grooves 4. An air outlet pipe 6 for spraying gas is fixedly connected to the rubber block 5, and the air outlet pipe 6 is inclined, and the air outlet pipe 6 is inclined towards the extrusion device 1. Since the rubber block 5 has a certain deformation ability, the air outlet pipe 6 can swing, which can change the gas action direction, thereby expanding the gas action range.

[0040] Specifically, when the gas inside the air outlet ring box 3 is sprayed out from the air outlet pipe 6, due to the inclined setting of the air outlet pipe 6, the gas acts on the cable obliquely, ensuring a large contact area between the gas and the cable and ensuring the drying effect.

[0041] Refer to Figure 4 、 Figure 6As shown in the figure, an airbag 7 is fixedly connected to the outside of the air outlet ring box 3. The airbag 7 is located on the side of the air outlet ring box 3 facing away from the extrusion equipment 1. One end of the airbag 7 away from the air outlet ring box 3 is fixedly connected to the inner wall of the drying cylinder 2. The airbag 7 is communicated with the factory high-temperature gas conveying pipeline, and the temperature of the high-temperature gas is appropriate, which only has the effect of accelerating the drying of the cable and will not cause the cable outer skin to soften or the like; the airbag 7 is provided. When gas is conveyed into the airbag 7, the expansion of the airbag 7 will push the air outlet ring box 3 to move towards the extrusion equipment 1 to adjust the position of the air outlet ring box 3.

[0042] The airbag 7 can be made of rubber material and has a certain elasticity.

[0043] Refer to Figure 6 As shown in the figure, a ring groove 8 is opened on the side of the air outlet ring box 3 close to the airbag 7. The air outlet ring box 3 is communicated with the airbag 7 through the ring groove 8. Gas can be conveyed into the interior of the air outlet ring box 3 from the airbag 7 and the ring groove 8. A ring plate 9 is arranged inside the airbag 7, and the ring plate 9 can close the ring groove 8. In specific use, a rubber pad can be arranged on the side of the ring plate 9 close to the air outlet ring box 3 to improve the sealing performance of the closing of the ring groove 8.

[0044] During actual use, control the ring plate 9 to fit on the outer wall of the air outlet ring box 3 to close the ring groove 8, convey gas into the airbag 7, and the inflation and expansion of the airbag 7 will push the air outlet ring box 3 to move axially along the drying cylinder 2; then control the ring plate 9 to reset, the ring groove 8 is opened, and the gas enters the interior of the air outlet ring box 3 from the ring groove 8 and is ejected from the air outlet pipe 6 to act on the cable to achieve the drying effect; at the same time, since the ring groove 8 is opened, the gas accumulated inside the airbag 7 is discharged towards the air outlet ring box 3, so that the airbag 7 shrinks, and under the assistance of the contraction elasticity of the airbag 7, the gas is accelerated to be ejected from the air outlet pipe 6 to achieve the effect of gas acceleration.

[0045] At the same time, the contraction of the airbag 7 will drive the air outlet ring box 3 and the air outlet pipe 6 to reset and move, change the gas action position, perform mobile air supply, and accelerate air flow.

[0046] Moreover, during the reset movement of the air outlet ring box 3 and the air outlet pipe 6, on the premise of ensuring that the ring groove 8 will not be closed, control the ring plate 9 to move back and forth, and with the cooperation of the rubber block 5, the ring plate 9 drives the air outlet pipe 6 to swing by using the connecting component to change the gas action direction.

[0047] In addition, the swing amplitude of the air outlet pipe 6 can be adjusted according to the specific use situation. In the present invention: during the swing of the air outlet pipe 6, it is ensured that it is inclined towards the extrusion equipment 1, and the gas will always act on the cable obliquely to ensure the contact area with the cable.

[0048] After the air outlet ring box 3 and the air outlet pipe 6 are reset, the ring plate 9 can be controlled to fit on the outer wall of the air outlet ring box 3 to close the ring groove 8 again, and the operation is repeated multiple times to achieve periodic acceleration of the gas ejection speed.

[0049] By providing structures such as the air outlet ring box 3, rubber block 5, airbag 7, etc., the present invention realizes periodically accelerating the gas ejection speed, brings mobile air supply, and at the same time uses the swing of the air outlet pipe 6 to change the gas action direction, ensuring the drying effect and improving the use efficiency of the extrusion device for photovoltaic cable production.

[0050] Refer to Figure 4 、 Figure 5 As shown in

[0051] , a suction ring box 18 cooperating with the air outlet ring box 3 is provided inside the drying cylinder 2, and the suction ring box 18 is located on the side of the air outlet ring box 3 facing away from the airbag 7. The suction ring box 18 is fixedly connected to the inner wall of the drying cylinder 2. There is a certain distance between the suction ring box 18 and the air outlet ring box 3, which does not affect the movement of the air outlet ring box 3. The drying cylinder 2 is communicated with the factory gas suction pipeline; suction holes 19 are provided on the suction ring box 18. The suction holes 19 can be located on the side of the suction ring box 18 facing the air outlet ring box 3. A plurality of suction holes 19 are provided. The suction ring box 18 and the suction holes 19 are used to suck the water vapor generated during the drying process.

[0052] Specifically, high-temperature gas is conveyed to the cable by the air outlet ring box 3 and the air outlet pipe 6, and is sucked by the suction ring box 18 and the suction holes 19. Thus, an air flow for drying the cable is formed inside the drying cylinder 2, that is, between the air outlet ring box 3 and the suction ring box 18, and the water vapor is sucked away in time to prevent the cable from being wetted again.

[0053] The present invention forms a drying air flow inside the drying cylinder 2. Compared with the direct blowing method in the prior art, the efficiency is better, and the influence of external impurities is avoided during the drying process.

[0053] In addition, a wind power circulation mechanism can be provided outside the drying cylinder 2 to cooperate with the air outlet ring box 3 and the suction ring box 18. The wind power circulation mechanism includes structures such as a pump body, an electric heating wire, a filter screen, etc. The sucked gas is filtered, heated and other processed and then transported back to the drying cylinder 2 again. The wind power circulation mechanism is a common technology in the prior art and will not be elaborated here and can be adjusted according to specific situations.

[0054] Refer to Figure 6 As shown in

[0055] , the connection assembly includes a connecting rod 13, a sliding channel 14 and a round block 15. The sliding channel 14 is opened at one end of the air outlet pipe 6 located inside the air outlet ring box 3. The round block 15 is arranged inside the sliding channel 14. One end of the connecting rod 13 is fixedly connected to the round block 15, and the other end of the connecting rod 13 passes through the annular groove 8 and is fixedly connected to the annular plate 9. The cooperation between the annular plate 9 and the air outlet pipe 6 is realized through the connection assembly.

[0056] The present invention can realize the swing of the air outlet pipe 6 while controlling the closed or open state of the annular groove 8 by arranging structures such as an annular plate 9 and a connecting component.

[0057] Referring to Figure 6 、 Figure 7 As shown in

[0058] a control mechanism for driving the annular plate 9 to move is arranged inside the airbag 7. The control mechanism includes an electric push rod 11 and a bracket 12. The bracket 12 is L-shaped. The electric push rod 11 is fixedly connected to the outer wall of the air outlet ring box 3. The bracket 12 is fixedly connected to the telescopic end of the electric push rod 11. The annular plate 9 is fixedly connected to the bracket 12. By driving the annular plate 9 to move through the control mechanism, the annular groove 8 is closed to control the swing of the air outlet pipe 6.

[0059] During actual use, control the telescopic end of the electric push rod 11 to extend, driving the annular plate 9 to move away from the air outlet ring box 3, and the annular groove 8 is opened; control the telescopic end of the electric push rod 11 to retract, driving the annular plate 9 to move towards the air outlet ring box 3, and the annular plate 9 fits on the outer wall of the air outlet ring box 3, and the annular groove 8 is closed.

[0059] Furthermore, control the telescopic end of the electric push rod 11 to extend and retract reciprocally, the annular plate 9 moves back and forth, driving the air outlet pipe 6 to swing.

[0060] Referring to Figure 5 As shown in

[0061] a fixing ring 17 is fixedly connected inside the drying cylinder 2, and the fixing ring 17 is located at one end of the drying cylinder 2 close to the extrusion equipment 1. A sponge ring 20 is fixedly connected to the fixing ring 17, and the sponge ring 20 is located on the side of the fixing ring 17 facing away from the extrusion equipment 1.

[0062] The cable sequentially passes through the fixing ring 17, the sponge ring 20, the suction ring box 18, the air outlet ring box 3 and the airbag 7.

[0063] When the cable passes through the sponge ring 20, the sponge ring 20 adsorbs the coolant on the surface of the cable, facilitating subsequent air supply and drying treatment. Figure 5 、 Figure 8 Considering that after the sponge ring 20 is used for a long time, due to the large amount of adsorbed coolant, the use effect will decline. To ensure the adsorption effect of the sponge ring 20, referring to

[0064] During actual use, the extrusion mechanism moves towards the sponge ring 20. The insertion ring 21 extends into the inner ring of the sponge ring 20 and penetrates through the fixing ring 17. The pressing ring 22 presses the sponge ring 20. Part of the coolant is discharged from the outer ring of the sponge ring 20, and part of the coolant is discharged through the through hole 23. The through hole 23 is inclined to facilitate the discharge of the coolant. At the same time, the insertion ring 21, the fixing ring 17, and the pressing ring 22 form a surrounding structure to reduce the attachment of the extruded coolant to the cable.

[0065] Furthermore, when the extrusion mechanism moves back to its original position away from the sponge ring 20, the sponge ring 20 continues to maintain a good adsorption effect.

[0066] Refer to Figure 4 、 Figure 5 As shown, the air outlet ring box 3 drives the extrusion mechanism to move synchronously by means of a linkage component. The linkage component includes a first round rod 24, a spring 25, and a support plate 26. The support plate 26 is fixedly connected to the outside of the insertion ring 21. One end of the first round rod 24 is fixedly connected to the outer wall of the air outlet ring box 3, and the other end of the first round rod 24 is fixedly connected to the support plate 26. A through groove for the first round rod 24 to pass through is provided on the wall of the drying cylinder 2 to ensure the stability of the sliding of the first round rod 24, thereby ensuring the stability of the extrusion mechanism, the air outlet ring box 3, etc. The spring 25 is sleeved on the outer wall of the first round rod 24. One end of the spring 25 is fixedly connected to the support plate 26, and the other end of the spring 25 is fixedly connected to the inner wall of the drying cylinder 2. By setting the linkage component, the cooperation between the extrusion mechanism and the air outlet ring box 3 and other structures is realized.

[0067] During actual use, when the air outlet ring box 3 moves towards the extrusion equipment 1 under the action of the expansion of the airbag 7, it will drive the extrusion mechanism to move synchronously through the first round rod 24 and the support plate 26. The spring 25 is stretched, and the extrusion mechanism squeezes the sponge ring 20. When the air outlet ring box 3 returns to its original position, the extrusion mechanism returns to its original position synchronously without affecting the use of the sponge ring 20, thereby realizing the periodic extrusion of the sponge ring 20.

[0068] Moreover, the reset elastic force of the spring 25 can assist the reset of the air outlet ring box 3 and other structures.

[0069] In the present invention, by setting structures such as the extrusion mechanism and the linkage component, the movement of the air outlet ring box 3 is used to drive the extrusion mechanism to move synchronously, and the periodic extrusion of the sponge ring 20 is realized, ensuring the adsorption effect of the sponge ring 20.

[0070] In addition, the insertion ring 21, the fixing ring 17, and the pressing ring 22 form a surrounding structure to improve the extrusion effect of the sponge ring 20.

[0071] Considering that the coolant extruded from the sponge ring 20 will fall to the bottom end of the drying cylinder 2, in order to realize the discharge of the coolant, refer to Figure 4 、 Figure 5As shown in the figure, a drain pipe 27 for discharging the coolant extruded from the sponge is connected to the bottom end of the drying cylinder 2, and a collection container (such as a bucket, etc.) can be placed below the drain pipe 27; a cover plate 29 cooperating with the drain pipe 27 is arranged inside the drying cylinder 2. The cover plate 29 fits on the bottom end of the drying cylinder 2, and the opening and closing of the drain pipe 27 are realized by means of the cover plate 29.

[0072] The extrusion mechanism drives the cover plate 29 to move synchronously by means of the connection assembly. The connection assembly includes a second round rod 28. One end of the second round rod 28 is fixedly connected to the pressing ring 22, and the other end of the second round rod 28 is fixedly connected to the cover plate 29. The cover plate 29 can move synchronously with the extrusion mechanism.

[0073] During actual use, when the extrusion mechanism moves towards the sponge ring 20, it will drive the cover plate 29 to move synchronously through the second round rod 28. When the extrusion mechanism squeezes the sponge ring 20, the cover plate 29 moves to the position between the fixed ring 17 and the drain pipe 27, and the top end of the drain pipe 27 is opened to discharge the extruded coolant; when the extrusion mechanism resets, the cover plate 29 closes the top end of the drain pipe 27 to prevent the drain pipe 27 from remaining open continuously, preventing external air from entering through the drain pipe 27 and interfering with the use of suction structures such as the suction holes 19 and the suction ring box 18, and ensuring the drying efficiency.

[0074] By setting structures such as the connection assembly, the drain pipe 27 and the cover plate 29, the present invention quickly discharges the coolant extruded from the sponge ring 20, and drives the cover plate 29 to move synchronously by means of the connection assembly to realize the opening or closing of the drain pipe 27, avoiding affecting the drying efficiency.

[0075] Refer to Figure 4 As shown in the figure, guiding components 10 are arranged at both ends inside the drying cylinder 2. The guiding components 10 include structures such as guide wheels and elastic members, which play an effect of guiding the cable. An electric traction device (including structures such as a motor) can also be set to drive the cable to move. The guiding components 10 and the traction device are both common existing technologies and will not be elaborated here. And structures such as a rubber ring 16 can also be arranged inside the drying cylinder 2. For example, at both ends of the drying cylinder 2, the cable passes through the rubber ring 16, which plays a partitioning effect and reduces the influence of the external environment on the drying process. The rubber ring 16 can also be installed at other positions and adjusted according to the specific use situation.
