Description

Technical Field

[0001] This invention relates to the field of cable sheathing technology, specifically to a sheathing and molding equipment and method for cable processing. Background Technology

[0002] The cable core is the conductive part of a power cable, used to transmit electrical energy, and is the main component of the power cable. Currently, copper or aluminum is generally used for the cable core. During processing, a layer of rubber is often wrapped around the cable core to achieve insulation, which requires overcoating equipment. The overcoating equipment mainly consists of a overcoating machine and a cooling box. After the cable is wrapped with a layer of rubber by the overcoating machine, it is pulled into the cooling box for cooling. The cooling methods in the cooling box are spray cooling and immersion cooling. Regardless of the cooling method, in order to ensure the cooling effect of the cable surface overcoating, the cable needs to stay in the cooling box for a certain period of time before it can be discharged. However, the cooling time of the cable surface overcoating is affected by various factors, such as the cable material size and the overcoating thickness. The cable movement path length in the existing cooling box is fixed. Under the condition of ensuring a fast cable movement speed, i.e., processing rate, a long cable movement path in the cooling box will cause overcooling, while a short cable movement path in the cooling box will cause undercooling. Summary of the Invention

[0013] A method for overcoating and molding cables, applicable to the aforementioned overcoating and molding equipment for cable processing, comprising the following steps:

[0014] S1: After the cable passes through the coating channel in the coating machine, the cable will go around the guide roller in the cable inlet hole. The cable that goes around the guide roller in the cable inlet hole will go around the fixed roller behind and the movable roller in front, and then around the guide roller in the cable outlet hole.

[0015] S2: Move the corresponding top block forward along the top groove. The moved top block drives the linked top block forward through the one-way bar. The forward movement of the top block will drive the movable roller and the bottom block to move forward and then lock.

[0016] S3: Pour the coating material into the melting cylinder of the coating machine. After the raw material in the melting cylinder melts, it enters the coating machine. As the cable is pulled by the traction mechanism, the cable will move from left to right. After passing through the coating machine, the cable is coated with an insulation layer. The coated cable enters along the cable inlet hole under the cable traction. The coated cable will bypass the guide roller in the cable inlet hole and enter the inner side of the cooling box.

[0017] S4: The nozzles on the front and back sides of the cooling box will continuously spray coolant. After the coolant comes into contact with the wrapped cable, it can carry away the heat of the cable surface coating. After the wrapped cable is cooled and formed in the cooling box, it moves out along the outer wall of the guide roller in the cable outlet hole.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention controls the movement of the movable roller away from and towards the fixed roller in the cooling box, thereby changing the path length of the cable in the cooling box. This allows the cable to cool in the cooling box in accordance with the cooling requirements without affecting the transmission speed, thus avoiding insufficient or excessive cooling of the cable surface coating.

[0020] 2. This invention allows the bottom block to slide and lock within the bottom groove, and the top block to slide and lock within the top groove, thereby supporting both the upper and lower ends of the movable roller. This makes the cable transmission after the movable roller is covered more stable. In addition, the multiple top and bottom blocks can be unlocked by pressing the drive rod, which greatly facilitates the use of the coating forming equipment compared to unlocking them sequentially.

[0021] 3. This invention, through the assistance of the one-way bar, enables the top block to move forward while the operator pushes one of the top blocks forward, and the top block can drive all the top blocks on the left side to move forward through the one-way bar. This achieves rapid forward adjustment of multiple top blocks, which further improves the adjustment efficiency of the top blocks to the forward movement of the movable roller compared to the original method of adjusting the top blocks sequentially, and is more convenient to use.

[0022] 4. In this invention, the two adapting blocks move closer to each other under the action of their respective springs. The adapting blocks will drive their respective connected adapting rings to move closer to each other, so that the adapting rings are always in close contact with the cable outer wall covering layer in the annular channel. The cable outer wall covering layer is guaranteed to have a good covering effect under the limiting compression of the adapting rings, while reducing the deformation of the covered cable after transmission. The two movable adapting rings can be used for cables of different specifications, and have a wide range of applications. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1 to 10 As shown, the present invention includes the following embodiments:

[0037] Example 1: A cable coating forming device includes a base 1; a coating machine 2 and a cooling box 3 are fixedly connected to the upper surface of the base 1; a coating channel 21 is provided through the coating machine 2 in the left-right direction; the cable inlet 31 and cable outlet 32 ​​of the cooling box 3 are aligned with the coating channel 21; the cable inlet 31 is close to the coating channel 21; the cable passes through the coating machine 2 and then through the cable inlet 31 and cable outlet 32 ​​into the cooling box 3; a nozzle 33 is provided in the front-back direction on the inner side of the cooling box 3; a liquid outlet is provided at the bottom of the cooling box 3. The cable inlet 31 and outlet 32 ​​are square in shape and are rotatably connected to the guide roller 4. The cooling box 3 is rotatably connected to the fixed roller 5. The fixed roller 5 is located near the rear side of the cooling box 3. The top of the cooling box 3 is movably connected to the top block 6. The lower surface of the top block 6 is rotatably connected to the movable roller 7. Multiple movable rollers 7 and multiple fixed rollers 5 are staggered in the left and right direction. The cable meanders around the fixed roller 5 and the movable roller 7 under the guidance of the guide roller 4. The top block 6 can be locked after moving in the front and back direction.

[0038] In this embodiment, a top groove 35 is provided through the top of the cooling box 3; the top groove 35 is elongated and its length direction is front-to-back; the top block 6 is slidably connected within the top groove 35; the rear side of the top block 6 is connected to the rear wall of the top groove 35 by a tension spring 61; the longer vertical wall of the top groove 35 is provided with a top retaining groove 36; multiple top retaining grooves 36 are spaced apart in the front-to-back direction; the side of the top block 6 facing the top retaining groove 36 is provided with a top recess 62; the top... A top locking block 63 is slidably connected within the groove 62; the top locking block 63 has a top inclined surface 64 inclined forward at one end near the top locking groove 36; the top locking block 63 is connected to the bottom of the groove 62 by an upper spring 65; the top surface of the top block 6 has a groove 66 communicating with the top groove 62; a lever 67 is slidably connected within the groove 66; the lever 67 is fixedly connected to the top locking block 63; the lever 67 can move the top locking block 63 out of the corresponding top locking groove 36 when it is levered.

[0039] The cable moves from left to right. Before cable wrapping, the worker passes the cable through the wrapping channel 21 in the wrapping machine 2. The cable then passes around the guide roller 4 in the cable inlet 31. The number of fixed rollers 5 is always one more than the number of movable rollers 7. Taking four fixed rollers 5 and three movable rollers 7 as an example, the cable passing through the guide roller 4 in the cable inlet 31 will pass behind the first fixed roller 5 and then around the front of the first movable roller 7. The cable passing through the front of the first movable roller 7 will pass behind the second fixed roller 5 and continue to pass around the front of the second movable roller 7. The cable that passes over the front side of the moving roller 7 will pass over the rear side of the third fixed roller 5 and continue to pass over the front side of the third moving roller 7. The cable that passes over the front side of the third moving roller 7 will pass over the rear side of the fourth fixed roller 5 and continue to pass over the guide roller 4 in the cable exit hole 32, completing the cable pre-installation process. Afterwards, the operator will adjust the cable path length in the cooling box 3 according to factors such as cable diameter, material, and sheath thickness. The cable needs to maintain a high transmission speed to ensure cable processing efficiency; therefore, the cable speed will not be changed to indirectly adjust the time the cable spends in the cooling box 3. Therefore, the operator will... The cooling time of the cable surface coating can be changed by extending or shortening the cable's path within the cooling box 3. When extending the cable's path within the cooling box 3 is necessary, the operator directly moves the top block 6 forward along the top groove 35. During this forward movement, the top locking block 63 moves forward, causing the top inclined surface 64 to contact the corresponding top locking groove 36. When the top inclined surface 64 is pressed against the top locking groove 36, the top locking block 63 is compressed, overcoming the upper spring 65 and retracting into the top recess 62 to avoid obstruction. This allows the top block 6 to smoothly move forward along the top groove 35 after unlocking. During the forward movement of the top block 6, the tension of the spring 61 is required. During the forward movement of the top block 6, the lower movable roller 7 is moved forward. During the forward movement of the movable roller 7, the path of the cable in the cooling box 3 will be lengthened. The specific number of movable rollers 7 to move forward is controlled according to the calculation requirements. After the top block 6 is moved, the top groove 62 on the top block 6 is aligned with the top slot 36. The upper spring 65 will push the top slot 63 to lock into the top slot 36 along the top groove 62, thereby locking the top block 6. After the top block 6 is locked, the adjusted position of the movable roller 7 is locked, and the path length of the cable in the cooling box 3 is also locked.Similarly, when it is necessary to shorten the cable path in the cooling box 3, the operator will move the lever 67 along the lever groove 66. After being moved, the lever 67 will overcome the upper spring 65 and drive the top locking block 63 to slide in the top groove 62. The end of the top locking block 63 away from the upper spring 65 will move out from the corresponding top locking groove 36, thereby unlocking the top block 6. Then, the top block 6 is controlled to slide backward along the top groove 35. The top block 6 is pulled backward by the tension spring 61 and drives the movable roller 7 to move backward. After the top block 6 has moved, the upper spring 65 will push the top locking block 63 to lock into the top locking groove 36 along the top groove 62, thereby locking the top block 6 again. In this way, the length of the cable path in the cooling box 3 is determined.

[0040] Next, the staff will use the traction mechanism to pull the cable, keeping it taut. Then, the coating material will be poured into the melting cylinder of the coating machine 2. After the raw material in the melting cylinder melts, it will enter the coating machine 2. As the cable is pulled by the traction mechanism, it will move from left to right. After passing through the coating machine 2, the cable will be coated with an insulation layer. The coated cable will then enter along the cable inlet 31 under the cable traction. The coated cable will bypass the guide roller 4 in the cable inlet 31 and enter the inner side of the cooling box 3. The nozzles 33 on the front and back sides of the cooling box 3 will... Coolant is continuously sprayed out. When the coolant comes into contact with the cable, it can carry away the heat of the cable's surface coating, thus solidifying and shaping the cable coating. The coated cable meanders back and forth around the fixed roller 5 and the movable roller 7, making the insulation layer bond more tightly with the outer wall of the cable. After the coolant comes into contact with the coated cable, it will gather on the inner bottom wall of the cooling tank 3 and finally flow out along the liquid outlet pipe 34 for recycling. After the coated cable is cooled and shaped in the cooling tank 3, it moves out along the outer wall of the guide roller 4 in the cable outlet hole 32.

[0041] This invention controls the movement of the movable roller 7 away from and towards the fixed roller 5 in the cooling box 3, thereby changing the path length of the cable in the cooling box 3. This allows the cable to cool in the cooling box 3 without affecting the transmission speed, so that the cooling time of the cable in the cooling box 3 is adapted to the cooling requirements, avoiding insufficient or excessive cooling of the cable surface coating.

[0042] Example 2: The bottom wall of the cooling box 3 is provided with a bottom groove 37 along the front-to-back direction; the bottom groove 37 is located directly below the top groove 35; the bottom groove 37 is slidably connected to the bottom block 8; the upper surface of the bottom block 8 is rotatably connected to the lower end of the corresponding movable roller 7; the longer vertical groove wall of the bottom groove 37 is provided with a bottom locking groove 38; multiple bottom locking grooves 38 are spaced apart in the front-to-back direction; the bottom block 8 is provided with a bottom groove 81 on the side facing the bottom locking groove 38; a bottom locking block 82 is slidably connected in the bottom groove 81; the bottom locking block 82 is provided with a bottom inclined surface 83 at the end near the bottom locking groove 38; the bottom locking block 82 and the bottom of the bottom groove 81 are connected by a lower spring 84.

[0043] In this embodiment, a blocking block 39 is slidably and sealingly connected to the top slot 36 and the bottom slot 38; the blocking block 39 is connected to the bottom of the top slot 36 or the bottom slot 38 by a limiting rope 391; a drive shell 9 is provided at the inner corner of the cooling box 3; a drive plate 91 is slidably and sealingly connected to the drive shell 9; a drive rod 92 is fixedly connected to the upper surface of the drive plate 91; the upper end of the drive rod 92 passes through the cooling box 3; the lower surface of the drive plate 91 is connected to the bottom wall of the drive shell 9 by a return spring 93; the drive plate 91 divides the drive shell 9 into an upper cavity 94 and a lower cavity 95; the lower cavity 95 is connected to the bottom of the top slot 36 and the bottom slot 38 through a liquid hole 96.

[0044] As the operator moves the top block 6 forward within the top groove 35, the top block 6 causes the top locking block 63 within the top recess 62 to move forward. The top locking block 63 retracts under the pressure of the top inclined surface 64, unlocking the mechanism. During this forward movement, the top block 6 also moves the movable roller 7 forward, which in turn moves the bottom block 8 forward within the bottom groove 37. This forward movement of the bottom block 8 causes the bottom locking block 82 within the bottom recess 81 to move forward as well. As the bottom block 8 moves forward, it becomes misaligned with the corresponding bottom locking groove 38. The opening of the bottom locking groove 38 then presses against the bottom inclined surface 83 on the bottom locking block 82, causing the bottom inclined surface 83 to retract into the bottom recess 81, thus unlocking the bottom block 8 from the bottom groove 37. As the bottom block 8 moves forward to the appropriate position... Once positioned, the bottom groove 81 aligns with the corresponding bottom slot 38, and the lower spring 84 pushes the bottom block 82 into the bottom slot 38, locking the bottom block 8 within the bottom groove 37. Since both the upper and lower ends of the movable roller 7 are locked, the stability of the movable roller 7 in driving the wrapped cable is improved. When it is necessary to control the top block 6 and bottom block 8 to move backward, simply press the drive rod 92 downward. During the downward movement of the drive rod 92, the drive plate 91 will move downward within the drive housing 9. During the downward movement of the drive plate 91, it will compress the reset spring 93 and simultaneously compress the lower cavity 95. The upper cavity 94 is connected to the outside gas. After the lower cavity 95 is compressed, the liquid medium inside the lower cavity 95 will enter along the liquid hole 96. The liquid medium enters the top slot 36 and the bottom slot 38. The liquid medium in the top slot 36 compresses the block 39, causing it to push away the top block 63, thus unlocking the top block 6. Similarly, the liquid medium in the bottom slot 38 compresses the block 39, causing it to push away the bottom block 8, thus unlocking the bottom block 8. The tension spring 61 then pulls the top block 6, the movable roller 7, and the bottom block 8 to move backward automatically. The limiting rope 391 limits the block 39, preventing it from moving out of the top slot 36 or the bottom slot 38. After the movable roller 7 moves to an appropriate position, the pressure on the drive rod 9 is stopped. 2. The reset spring 93 pushes the drive plate 91 upward, creating a negative pressure in the lower cavity 95. The liquid medium in the top slot 36 and bottom slot 38 is drawn back into the lower cavity 95, and the locking blocks in the top slot 36 and bottom slot 38 return to their original positions, allowing the slots of the top slot 36 and bottom slot 38 to re-expose. In this embodiment, the bottom block 8 slides and locks in the bottom slot 37, and the top block 6 slides and locks in the top slot 35, thereby supporting both the upper and lower ends of the movable roller 7. This makes the cable transmission after the movable roller 7 is covered more stable. In addition, the multiple top blocks 6 and bottom blocks 8 can be unlocked by pressing the drive rod 92, which greatly facilitates the use of the coating molding equipment compared to unlocking them sequentially.

[0045] Example 3: There are multiple top grooves 35 and bottom grooves 37, which are spaced apart along the left and right directions; the top block 6 protrudes from the top groove 35 at one end; the top block 6 is fixedly connected to one-way strips 68 in the left and right directions; the one-way strips 68 on the top block 6 overlap in the left and right directions; the one-way strip 68 on the right side of the top block 6 overlaps the front side of the one-way strip 68 on the left side of the adjacent top block 6.

[0046] The length of the transmission path of the covered cable in the cooling box 3 can be adjusted according to the requirements. For multiple top blocks 6, adjusting the top blocks 6 forward sequentially will affect the adjustment efficiency. Therefore, with the assistance of the one-way bar 68, when the operator pushes one of the top blocks 6 forward, the top block 6 can drive all the top blocks 6 on the left side to move forward through the one-way bar 68, thereby realizing the rapid forward adjustment of multiple top blocks 6. Compared with the original method of adjusting the top blocks 6 sequentially, this further improves the adjustment efficiency of the top blocks 6 on the forward movement of the movable roller 7 and makes it more convenient to use.

[0047] Example 4: The guide roller 4, fixed roller 5, and movable roller 7 are provided with adaptation grooves 41 at the upper and lower positions on their outer walls; adaptation blocks 42 are slidably connected in the adaptation grooves 41; the two adaptation blocks 42 are connected to the two adaptation grooves 41 at opposite ends by a central spring 43; the outer wall of the adaptation blocks 42 is connected to an adaptation ring 44; the guide roller 4, fixed roller 5, and movable roller 7 have the same outer diameter and are all fitted with adaptation rings 44; the two adaptation rings 44 are close to each other to form a V-shaped annular track 45; the cable is driven within the annular track 45.

[0048] In this embodiment, the adapting block 42 is L-shaped; the longer ends of the two adapting blocks 42 are arranged close to each other.

[0049] After the cable passes over the outer walls of the guide roller 4, fixed roller 5, and movable roller 7, the guide roller 4, fixed roller 5, and movable roller 7 will rotate as the cable is driven. The outer walls of the guide roller 4, fixed roller 5, and movable roller 7 are all provided with adaptation grooves 41. The spring 43 in the adaptation groove 41 will transmit the elastic force to the adaptation block 42 in the adaptation groove 41. The two adaptation blocks 42 move closer to each other under the elastic force of their respective springs 43. The adaptation blocks 42 will drive their respective connected adaptation rings 44 to move closer to each other. In this way, the adaptation rings 44 are always in close contact with the cable outer wall covering layer in the annular track 45. The covering layer on the cable outer wall is guaranteed to have a good covering effect under the limiting compression of the adaptation rings 44, while reducing the deformation of the covered cable after transmission. The two movable adaptation rings 44 can be used for cables of different specifications, with a wide range of applications. The adaptation block 42 is L-shaped, so that the middle section of the outer wall of the guide roller 4, fixed roller 5, and movable roller 7 is not provided with adaptation grooves 41 to ensure the smoothness of the annular track 45.

[0050] Example 5: The plurality of movable rollers 7 are spaced apart in the left-right direction; in the left-right direction, the odd-numbered movable rollers 7 are higher than the fixed rollers 5 in the vertical direction, and the even-numbered movable rollers 7 are lower than the fixed rollers 5 in the vertical direction.

[0051] In this embodiment, the two adaptation rings 44 are concentrically provided with annular grooves 46 on opposite sides; the two adaptation blocks 42 are slidably connected to the corresponding annular grooves 46 at opposite ends.

[0052] Since the odd-numbered movable rollers 7 are vertically higher than the fixed rollers 5, the annular tracks 45 on the outer walls of the guide rollers 4, fixed rollers 5, and movable rollers 7 are all located in the middle section. Therefore, the annular tracks 45 in the middle section of the odd-numbered movable rollers 7 are vertically higher than the annular tracks 45 on the outer wall of the middle section of the fixed rollers 5. Similarly, since the even-numbered movable rollers 7 are vertically lower than the fixed rollers 5, the annular tracks 45 in the middle section of the even-numbered movable rollers 7 are vertically lower than the annular tracks 45 on the outer wall of the middle section of the fixed rollers 5. Thus, during the process of the cable passing through the annular tracks 45 on the fixed rollers 5 and entering the annular tracks 45 on the odd-numbered movable rollers 7, the lower part of the cable's outer wall covering is squeezed by the inner side of the corresponding adaptation ring 44. Similarly, the annular tracks 45 on the fixed rollers 5 and 7... As the cable, bypassed by track 45, enters the annular track 45 on the even-numbered movable roller 7, the upper part of the cable's outer sheath is squeezed by the inner side of the corresponding adapting ring 44. This ensures that the sheath around the cable surface is squeezed down to ensure tightness and regularity, thereby improving the sheathing quality. In addition, since the annular groove 46 on the outer side of the adapting ring 44 is slidably connected to the adapting block 42, the adapting ring 44 does not rotate with the guide roller 4, fixed roller 5, and movable roller 7 during their rotation. This gives the adapting ring 44 its own degree of freedom, allowing it to reduce friction with the cable's outer sheath while ensuring a good limiting and squeezing effect.

[0053] Example 6: A method for overcoating and molding for cable processing, applicable to the overcoating and molding equipment for cable processing described above, the steps of which are as follows:

[0054] S1: After the cable passes through the coating channel 21 in the coating machine 2, the cable will pass around the guide roller 4 in the cable inlet 31. The cable passing around the guide roller 4 in the cable inlet 31 will pass around the fixed roller 5 backward and the movable roller 7 forward, and pass around the guide roller 4 in the cable outlet 32.

[0055] S2: Move the corresponding top block 6 forward along the top groove 35. The moved top block 6 drives the linked top block 6 to move forward through the one-way bar 68. The forward movement of the top block 6 will drive the movable roller 7 and the bottom block 8 to move forward and then lock.

[0056] S3: Pour the coating material into the melting cylinder of the coating machine 2. After the raw material in the melting cylinder melts, it enters the coating machine 2. As the cable is pulled by the traction mechanism, the cable will move from left to right. After passing through the coating machine 2, the cable is coated with an insulation layer. The coated cable enters along the cable inlet 31 under the cable traction. The coated cable will bypass the guide roller 4 in the cable inlet 31 and enter the inner side of the cooling box 3.

[0057] S4: The nozzles 33 on the front and rear sides of the cooling box 3 will continuously spray out coolant. After the coolant comes into contact with the wrapped cable, it can carry away the heat of the cable surface coating. After the wrapped cable is cooled and formed in the cooling box 3, it moves out along the outer wall of the guide roller 4 in the cable outlet hole 32.
