Description

Technical Field

[0001] The present invention relates to the technical field of wire processing equipment, and in particular to a wire processing device for wire production and processing. Background Art

[0002] A wire generally consists of three components: a core wire, an insulating sheath, and a protective outer sheath. In the wire production and processing technology, covering the insulating sheath outside the core wire is one of the wire processing technologies. Currently, the insulating sheath is generally made using an extruder.

[0003] Insert the core wire into the cable channel of the extruder, and pour the insulating material into the feeding system. The extruder will heat the insulating material into a molten state, and then the molten material is extruded from the extrusion die. Moreover, the core wire also moves out from the central position of the extrusion die. The molten material surrounds the core wire and adheres to the core wire to achieve the purpose of covering the core wire with an insulating sheath. Currently, the thickness of the insulating sheath covered by the cable extruder is generally the same. However, for some wires, due to the particularity of the application scenario, there will be insulating layers with different thicknesses locally on the same wire.

[0004] For example: in factories or mechanical equipment, wires often need to withstand high temperature, high pressure, or strong mechanical stress. In order to protect key parts, these wires may adopt locally thickened insulating layers;

[0005] Another example: wires used in life support systems require extremely high reliability and flexibility, and at the same time need to prevent electromagnetic interference; in these applications, it may be necessary to increase the insulating thickness in specific areas to ensure signal integrity and patient safety.

[0006] Currently, to produce wires with different local insulating layer thicknesses, it is possible to rely on the existing extruder to first produce wires with the same insulating layer thickness, and then perform secondary processing on the wires, locally heat some areas of the wire insulating layer, and then add one or more additional insulating materials to specific parts on the original extruder to achieve the thickening effect. However, this method requires multiple steps and is rather troublesome. Therefore, a wire processing device for wire production and processing is designed now to overcome the above defects.

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] A wire processing device for wire production and processing, such as Figure 1 - Figure 2 As shown, it includes a body 2 for supporting the entire device, a channel for the core wire 1 to pass through is arranged inside the body 2, the traction end of the core wire 1 is pulled by an existing traction device, an outer mold sleeve 3 is arranged on the side of the body 2, the outer mold sleeve 3 is arranged concentrically with the channel, and an inner mold sleeve 4 is arranged inside the outer mold sleeve 3;

[0030] The extrusion die of the existing extruder is usually composed of an inner die sleeve 4, an outer die sleeve 3 and other components. The core wire 1 passes through the inner die sleeve 4, and the outer die sleeve 3 is covered on the outer side of the inner die sleeve 4. The molten insulating layer material is extruded into a cylindrical shape from the cavity formed between the inner die sleeve 4 and the outer die sleeve 3. The extruded cylindrical material is covered on the core wire 1. Therefore, the thickness of the cavity between the inner die sleeve 4 and the outer die sleeve 3 directly determines the thickness of the outer insulating layer of the core wire 1.

[0031] However, in some special scenarios, there may be special design requirements for the wire production process. For example, on the same wire, different thicknesses of insulating layers need to be set locally. Such requirements usually stem from the requirements of specific application environments, such as the two scenarios mentioned in the foregoing background art. To meet these special design requirements, the prior art adopts a secondary processing method. The extruder first produces a wire with a uniform thickness of the insulating layer, and then adds one or more additional insulating materials to certain areas of the wire insulating layer to achieve the thickening effect.

[0032] Although the above method is feasible, it is very troublesome during the production process. Therefore, in this embodiment, further improvements are made on the basis of the existing extruder to meet the production requirements of insulating layers with different thicknesses:

[0033] In this embodiment, a plurality of cavities are arranged between the outer die sleeve 3 and the inner die sleeve 4. As Figure 2 shown, three cavities are provided, namely: cavity one 5, cavity two 6, and cavity three 7. The thickness of each cavity is the same, and the structure of each cavity is conical. The conical setting method can accelerate the flow rate of the molten insulating layer material. Cavity two 6 is arranged to surround cavity one 5, and cavity three 7 is arranged to surround cavity two 6. Under normal circumstances, the insulating layer material extruded through cavity one 5 can be wrapped around the core wire 1. If, during the wrapping process of the core wire 1, it is necessary to wrap a thicker insulating layer on a local position of the core wire 1, cavity two 6 can be opened. The molten insulating layer materials coming out from cavity one 5 and cavity two 6 together can form a double-thickness insulating layer. At the same time, if cavity two 6 and cavity three 7 are opened together, a triple-thickness insulating layer can be formed. Different thicknesses of insulating layers can be freely adjusted according to the actual situation. Moreover, during the wrapping operation, the thickness can be freely adjusted without stopping the wrapping operation, which is very convenient;

[0034] On the left side of the cavity, feeding ports 8 are arranged at equal intervals along the circumferential direction. The molten material will enter the cavity through the feeding ports 8 and flow out. It is necessary to open and close the feeding ports 8 to open and close the cavity. Inside the outer die sleeve 3, a perforated ring one 9, a perforated ring two 10, and a perforated ring three 11 are provided. The aperture sizes on the perforated rings are the same as those of the feeding ports 8, and the number of holes on the perforated rings is the same as the number of feeding ports 8. By rotating the perforated rings to open and close the feeding ports 8, the purpose of opening and closing different cavities can be achieved. The perforated ring one 9 is rotatably connected to the outer wall of the inner die sleeve 4, the perforated ring two 10 is rotatably connected to the outside of the perforated ring one 9, and the perforated ring three 11 is rotatably connected to the outside of the perforated ring two 10. In the initial state, the holes of the perforated ring one 9 communicate with the feeding ports 8 of the cavity one 5, the holes of the perforated ring two 10 communicate with the feeding ports 8 of the cavity two 6, and the holes of the perforated ring three 11 communicate with the feeding ports 8 of the cavity three 7. Therefore, the three cavities are in an open state. If it is necessary to close the cavity, the corresponding perforated ring can be rotated by an angle that is half of the included angle between two holes, so that the holes of the perforated ring are misaligned with the feeding ports 8 of the corresponding cavity, and the cavity is closed.

[0035] As described above, rotating the perforated ring can achieve the purpose of opening and closing the cavity. In this embodiment, a scheme for driving the perforated ring is proposed. As Figure 3 - Figure 4 shown, it includes a first connecting rod 12, which is fixedly connected to the first perforated ring 9. The end of the first connecting rod 12 is fixedly connected to a first rotating ring 13. The first rotating ring 13 is rotatably connected to the outer wall of the inner mold sleeve 4. An outer second rotating ring 16 is arranged outside the first rotating ring 13. The second rotating ring 16 is rotatably connected to the outside of the first rotating ring 13. The second rotating ring 16 is connected to a second connecting rod 15. One side of the second connecting rod 15 away from the second rotating ring 16 is connected to the second perforated ring 10. The third perforated ring 11 is fixedly connected to a third connecting rod 17. The other end of the third connecting rod 17 is fixedly connected to a rotating ring. The third rotating ring 18 is rotatably connected to the outside of the second rotating ring 16. When adjusting the opening and closing of the cavity, the driving component can be switched to the corresponding rotating ring according to requirements, and the driving component drives the rotating ring to rotate. The rotating ring drives the corresponding perforated ring to rotate by a specified angle through the connecting rod, and then the corresponding cavity can be opened. If it is necessary to close the cavity, continue to control the rotating ring to rotate by a specified angle, and the cavity can be automatically closed;

[0036] As Figure 3 - Figure 4 shown, the driving component includes a first wedge block 14, which is arranged on the rotating ring. A circle of equally spaced first wedge blocks 14 is arranged around each rotating ring. Therefore, the three circles of first wedge blocks 14 are horizontally and neatly distributed, and the gaps between each circle of first wedge blocks 14 are equal. A small motor 19 is provided on the inner mold sleeve 4. A telescopic rod 20 is connected to the output shaft of the small motor 19. The end of the telescopic rod 20 is fixedly connected to a tooth block 21. The tooth block 21 cooperates with the first wedge block 14. By the operation of the small motor 19, the telescopic rod 20 and the tooth block 21 are driven to rotate. When the tooth block 21 rotates, it will drive the first wedge block 14 to rotate, thereby driving the perforated ring to rotate. Since it is necessary to switch the driving position according to requirements, the telescopic rod 20 is provided, and people can adjust the left and right positions of the tooth block 21 according to requirements so that the tooth block 21 cooperates with the corresponding first wedge block 14.

[0037] It should be noted that: when the tooth block 21 moves left and right for adjustment, it needs to pass through the gap between the two first wedge blocks 14. Therefore, the size of the gap needs to be unified, otherwise it will affect the left and right adjustment of the tooth block 21. And when adjusting the perforated ring each time, the rotation angle of the first wedge block 14 is equal. Therefore, there will be no misalignment between each circle of first wedge blocks 14, that is, the gap between the two first wedge blocks 14 will not change. Therefore, the tooth block 21 will not be blocked when moving left and right.

[0038] To facilitate the adjustment of the position of the tooth block 21, a pulling rod 22 is provided on the telescopic rod 20. The pulling rod 22 is rotatably connected to the telescopic end of the telescopic rod 20, and the pulling rod 22 is slidably connected to the outer mold sleeve 3. People can pull the pulling rod 22 left and right by hand, so as to conveniently adjust the left and right positions of the tooth block 21. After adjusting the position of the tooth block 21, the small motor 19 needs to be turned on. Then, a switch button 23 is provided on the top of the outer mold sleeve 3. The switch button 23 and the small motor 19 are electrically connected through a control module. There are six switch buttons 23, with three on the left being off buttons and three on the right being on buttons. The three buttons respectively correspond to three gears. After adjusting the position of the tooth block 21, press the corresponding on button, and the small motor 19 will work for one second and then automatically stop working. If it is necessary to close the cavity of this gear, press the corresponding off button, and the small motor 19 will continue to work for one second and then automatically stop working;

[0039] In this embodiment, a circular ring partition 24 is provided on the outer mold sleeve 3. The circular ring partition 24 is fixedly connected to the outer mold sleeve 3, separating the outer mold sleeve 3 into two parts. The right side of the circular ring partition 24 is the molten material discharge space, and the left side of the circular ring partition 24 is the space where components such as the small motor 19, the telescopic rod 20, and the tooth block 21 are arranged. Moreover, the inner diameter of the circular ring partition 24 is slightly larger than the outer diameter of the inner mold sleeve 4. Therefore, there is a gap between the inner side of the circular ring partition 24 and the outer wall of the inner mold sleeve 4. The ring walls of the three rotating rings are accommodated in this gap, facilitating the connection of the rotating rings to the perforated ring located in the discharge space through the connecting rod;

[0040] In addition, equidistantly distributed feed holes are opened on the circular ring partition 24. The feed holes are connected to the feed pipe fittings 25. The feed pipe fittings 25 extend along the length direction of the outer mold sleeve 3 and penetrate through the feed pipe fittings 25. The feed pipe fittings 25 penetrate into the machine body 2. The side of the feed pipe fittings 25 close to the machine body 2 communicates with the feed pipe 26. The feed pipe 26 extends longitudinally upward and penetrates out of the machine body 2. The feed pipe 26 can be connected to the feeding equipment for transporting the molten material. The molten material enters the discharge space position through the feed pipe 26 and the feed pipe fittings 25.

[0041] According to the foregoing, during the process of covering the wire core, if it is necessary to locally thicken the insulating layer, multiple cavities must be opened. After the cavities are opened, the discharge opening increases. If the pressure for pushing the molten material is not adjusted accordingly, the same pushing pressure will cause the discharge speed of the molten material to decrease;

[0042] During the process of covering the wire core with the insulating layer, the moving speeds of the wire core and the insulating layer need to be accurately adjusted in advance to ensure the covering effect. However, if the covering thickness of the insulating layer is adjusted during the operation of the equipment but the pushing pressure of the molten material is not adjusted accordingly, it is easy to cause the flow rate of the molten material to not match the moving speed of the wire core, thereby affecting the covering quality;

[0043] In summary, to achieve an ideal coating effect, when adjusting the thickness of the insulating layer, it is necessary to synchronously adjust the pushing pressure of the molten material to ensure that the flow rate of the molten material is adapted to the moving speed of the wire core. In this embodiment, the air pressure regulator 29 and the pneumatic actuator 27 are combined and used;

[0044] As Figure 5 shown, the pneumatic actuator 27 is arranged at the top of the machine body 2. The pneumatic actuator 27 in the prior art usually consists of components such as a piston, a piston rod, a rack, and a gear. In this embodiment, corresponding adjustments are made to the pneumatic actuator 27 according to the specific implementation situation of this solution. The pneumatic actuator 27 of this solution includes two air inlet parts 28. The air outlet of the left air inlet part 28 communicating with the pipeline is arranged on the left side of the left piston, and the air outlet of the right air inlet part 28 is arranged at the cavity position between the two pistons. Therefore, when the left air inlet part 28 intakes air, the left piston is pushed to the right by air pressure. Due to the arrangement of the rack and the gear, the right piston is moved to the left. When the right air inlet part 28 intakes air, the two pistons are pushed to the side away from each other by air pressure. Therefore, by alternately intaking air through the air inlet parts 28, the two pistons can move in and out continuously, and the piston rods connected to the pistons will also move in and out accordingly. Therefore, the piston rods on both sides of the pneumatic actuator 27 are used as the driving force for pushing the molten material. The piston rods are connected to a material storage mechanism, and the molten material in the material storage mechanism is pushed to the feed pipe 26 for feeding through the movement of the piston rods;

[0045] The piston rod is used as the power source for pushing the molten material. If it is necessary to adjust the pushing pressure of the molten material, only the moving speed of the piston rod needs to be adjusted. Also, because the driving force of the pneumatic actuator 27 comes from air pressure, different air pressures will result in corresponding adjustments to the moving speed of the piston rod. Therefore, controlling the air pressure entering the pneumatic actuator 27 can adjust the speed of the piston rod. To achieve this goal, an air pressure regulator 29 can be added to the pneumatic actuator 27. By adjusting the intake air pressure of the air pressure regulator 29, the moving speed of the piston rod can be controlled, thereby adjusting the driving force when the piston rod pushes the molten material. This method can effectively solve the problem of the mismatch between the flow rate of the molten material and the moving speed of the wire core, and ensure the stability and quality of the coating process;

[0046] Therefore, pressure regulators 29 are arranged at the positions of the two air inlets 28 at the top of the pneumatic actuator 27. The two pressure regulators 29 are connected to the same air source, and the two pressure regulators 29 need to work alternately to achieve the purpose of the synchronous inward and outward movement of the piston rod. The pressure regulator 29 and the switch button 23 are electrically connected through a control module. According to the opening and closing of the cavity, the air pressure of the pressure regulator 29 will be automatically adjusted. The adjustment principle is as follows: when people press the opening key of the first gear, the cavity of the first gear opens, then the opening key will send an electrical signal, and after receiving the signal, the pressure regulator 29 will automatically adjust to the air pressure of the first gear. The air pressure of the first gear realizes that the pushing speed of the molten material is matched with the moving speed of the core wire 1. Similarly, when the cavity of the second gear opens, the pressure regulator 29 will automatically adjust to the air pressure of the second gear.

[0047] The storage mechanism set in this embodiment includes two storage cylinders 30. The storage cylinders 30 are fixedly connected to the top of the machine body 2. A piston member 31 is slidably connected in the storage cylinder 30. One of the piston members 31 is connected to one of the piston rods of the pneumatic actuator 27, and the other piston member 31 is connected to the other piston rod of the pneumatic actuator 27. When the piston rods move closer to each other, the two piston members 31 are driven to move in opposite directions at the same time. One of the piston members 31 performs the material suction work in the storage cylinder 30, and the other piston member 31 performs the material extrusion work in the storage cylinder 30. The two piston members 31 move in and out alternately, so that the two storage cylinders 30 discharge and feed materials alternately. A feed channel 32 is communicated between the two storage cylinders 30. The feed channel 32 is communicated with an external feeding device. A pipeline 33 is communicated between the two storage cylinders 30. The pipeline 33 is communicated with the feed pipe 26. Therefore, when the storage cylinder 30 feeds materials, the molten material in the feeding device will enter the storage cylinder 30. When the storage cylinder 30 discharges materials, the molten material in the storage cylinder 30 enters the feed pipe 26 through the pipeline 33.

[0048] When the molten material flows out of the cavity to the core wire, since the molten material is a fluid, there may be a situation where the molten material drips downward when it adheres to the core wire, which is likely to cause uneven thickness of the insulating layer on the core wire. For this reason, this embodiment proposes a solution to solve the dripping of the molten material. A closed cavity can be set at the position where the molten material flows out of the cavity. When the molten material flows into the closed cavity, the core wire stops moving. During this stopped period, the molten material can have enough time to stand still, so that it can adhere more firmly to the core wire. Then, when the closed cavity is opened, the core wire continues to move. Therefore, the moving mode of the core wire needs to be adjusted to be intermittent, and the pressure regulator 29 also intakes air intermittently to achieve intermittent discharging. Since this solution has the characteristic of adjusting the thickness of the insulating layer, the closed cavity also needs to be adjustable. Therefore, this solution proposes an iris mechanism. The characteristic of the iris mechanism is that it can freely adjust the space size. The specific solution is as follows:

[0049] As shown Figure 6 in the figure, on the side of the outer mold sleeve 3 away from the machine body 2, there is a fixedly connected mounting ring 34. A slant rail ring 35 is rotatably connected inside the mounting ring 34. A toggling member 36 is arranged at the top of the slant rail ring 35. The toggling member 36 is slidably connected to the mounting ring 34. The slant rail ring 35 is provided with equally spaced slant rails. The slant rails are provided with adjusting blocks 37. The adjusting blocks 37 are slidably connected to the slant rails. All the adjusting blocks 37 enclose a circular cavity. People can rotate the toggling member 36 to drive the rotation of the slant rail ring 35 according to the adjustment level of the cavity, so as to adjust the size of the cavity enclosed by the adjusting blocks 37;

[0050] In order to stably lock the size after adjustment, it is necessary to lock the position of the toggling member 36 after adjustment. An elastic lock head 38 is arranged on the toggling member 36. The elastic lock head 38 is fixedly connected to the toggling member 36. Three lock holes 39 are opened on the mounting ring 34. The lock holes 39 are in snap-fit connection with the elastic lock head 38. When the toggling member 36 rotates, it will drive the elastic lock head 38 to rotate. After the elastic lock head 38 contacts the lock hole 39, the elastic lock head 38 can be snapped into the lock hole 39, thereby locking the position of the toggling member 36.

[0051] In order to close the cavity, as Figure 7 shown in the figure, two closing plates 40 are arranged on the right side of the mounting ring 34. The closing plates 40 block the right side of the cavity, so as to form a closed cavity. Two bidirectional screws 41 are arranged between the closing plates 40. The bidirectional screws 41 are in threaded connection with the closing plates 40. When it is necessary to open the cavity, through the two bidirectional screws 41, the rotation of the bidirectional screws 41 drives the closing plates 40 to move away from each other to open the cavity, and the reverse rotation of the bidirectional screws 41 drives the closing plates 40 to move closer to each other to close the cavity;

[0052] A transmission belt 42 is arranged between the two bidirectional screws 41. The power source of the transmission belt 42 is a motor, and the motor works intermittently. Before the wire core moves, the motor works to make the closing plates 40 open the cavity. After the wire core stops moving, the motor works to make the closing plates 40 close the cavity.

[0053] As Figure 1 shown in the figure, a covering body 43 is arranged above the machine body 2. The covering body 43 is slidably connected above the machine body 2. The covering body 43 is used to shield components such as the pneumatic actuator 27 and the pressure regulator 29.
