Description

Technical Field

[0001] This invention relates to the field of insulating sheath production, specifically to a device for producing insulating sheaths for conductors. Background Technology

[0002] Insulating sleeves are mainly used to wrap the joints of wires to prevent leakage at the joints and provide insulation protection.

[0003] In existing technologies, insulating sleeves are produced by extruding them through an extruder, cooling them, and then winding them up through a winding mechanism. However, the winding mechanism in existing technologies requires stopping the machine after winding one roll, removing the wound insulating sleeve from the winding mechanism, replacing it with a new roll, and then restarting the machine to continue the work. Because this requires stopping the machine to wait for workers to remove the wound insulating sleeve from the winding mechanism, the downtime is long, resulting in low work efficiency.

[0014] The guide post is provided with a guide groove at the position corresponding to the guide rod. The guide groove includes a first guide groove and a second guide groove distributed circumferentially on the guide post. The second guide groove is vertically opened on the guide post. The first guide groove is inclinedly opened between two adjacent second guide grooves, with one end connected to the bottom of one of the second guide grooves and the other end connected to the top of the other second guide groove. The depth of the end of the first guide groove connected to the bottom of the second guide groove exceeds the depth of the bottom of the second guide groove, and the depth of the end of the first guide groove connected to the top of the second guide groove is not greater than the depth of the top of the second guide groove.

[0015] Preferably, the telescopic end of the telescopic component is a lifting plate, and the lifting plate has a first inner groove at the position corresponding to the guide rod. One end of the guide rod is inserted into the first inner groove, and a first elastic element is provided between the guide rod and the bottom of the first inner groove.

[0016] Preferably, the first elastic element is a spring.

[0017] Preferably, the lifting plate is provided with a guide sleeve at the position corresponding to the guide rod, and the guide rod slides through the guide sleeve.

[0018] Preferably, the cutting assembly cuts the insulating sheath by moving up and down; it also includes a clamping assembly disposed between the cutting assembly and the extruder, the clamping assembly comprising:

[0019] A round rod is disposed on one side of the extruder and located below the insulating sleeve to support the insulating sleeve;

[0026] Beneficial effects:

[0027] The worker secures one end of the extruded insulating sheath to a winding roller. Then, a drive unit starts, rotating the corresponding winding roller to wind up the insulating sheath. Once the winding roller reaches a certain thickness, the drive unit stops, and a cutting component cuts the insulating sheath. Simultaneously, the cutting component's movement, via a transmission component, drives a shifting component to move the winding roller with the insulating sheath wound on it to the outside. The winding roller, ready for winding, moves back to the extruder. This saves the worker's time unloading the insulating sheath, reducing operation time, downtime, and improving work efficiency.

[0036] 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.

[0037] In one embodiment, please refer to the appendix to the specification. Figure 1-2 As shown, the present invention provides a conductor insulation sheath production apparatus, which includes an extruder, a winding mechanism 4, and a cutting assembly. The cutting assembly is located between the winding mechanism 4 and the extruder and is used to cut the insulation sheath entering the winding mechanism 4.

[0038] The winding mechanism 4 includes a shifting component and a plurality of winding rollers 42 detachably disposed on the shifting component. The shifting component can move each winding roller 42 sequentially to the side close to the extruder. The shifting component is provided with a drive component for driving each winding roller 42 to rotate at the corresponding position of each winding roller 42. In this application, the drive component is a motor 43.

[0039] The cutting component is connected to the shifting component via a transmission component. During the cutting motion, the cutting component can drive the shifting component to shift position via the transmission component.

[0040] In practice, the worker fixes one end of the insulating sleeve extruded from extruder 1 onto the winding roller 42. Then, the drive unit starts, causing the corresponding winding roller 42 to rotate and wind up the insulating sleeve. When the winding roller 42 is wound to a certain thickness, the drive unit stops working, and then the cutting component cuts the insulating sleeve. At the same time, the cutting motion of the cutting component drives the shifting component through the transmission component to shift, so that the winding roller 42 with the insulating sleeve wound on it moves to the outside, and the winding roller 42 to be wound moves to extruder 1 to wait for winding. In this way, the worker's time for unloading the insulating sleeve is saved, the worker's operation time is shortened, and the downtime is reduced, thus improving work efficiency.

[0041] In one embodiment, please refer to the appendix to the specification. Figure 1-3 As shown, the cutting component includes:

[0042] Telescopic component 23 is disposed above the insulating sheath;

[0043] The first cutting blade 61 is mounted on the telescopic assembly 23 and located above the insulating sleeve. The telescopic assembly 23 can drive the first cutting blade 61 to move up and down in the vertical direction.

[0044] The second cutter 62 is located below the insulating sheath and is tangentially engaged with the first cutter 62.

[0045] A crossbeam 21 is provided on the support 2, and a telescopic component 23 is fixedly connected to the crossbeam 21. By fixing the second cutter 62 on the support 2, when the winding mechanism 4 completes winding, the telescopic component 23 on the support 2 will drive the first cutter 61 to move downward. The first cutter 61 will drive the insulating sleeve to abut against the second cutter 62. Since the first cutter 61 and the second cutter 62 are tangentially engaged, the first cutter 61 and the second cutter 62 work together to generate shearing force, which can easily cut the insulating sleeve located between the first cutter 61 and the second cutter 62.

[0046] In one embodiment, please refer to the appendix to the specification. Figure 1-2 As shown, the transposition assembly includes a bracket 2, a rotating shaft 41 rotatably mounted on the bracket 2, and at least two support rods 44 mounted at one end of the rotating shaft 41. Each of the rollers 42 is rotatably mounted on the corresponding support rod 44.

[0047] When it is necessary to wind up the insulating sleeve, the motor 43 is started. The rotation of the motor 43 drives the winding roller 42 to rotate, and the insulating sleeve is wound onto the winding roller 42 until the winding is completed. After the winding roller 42 is completed, the drive component drives the support rod 44 to rotate. The support rod 44 rotates around the rotation axis 41, thereby changing the position of the winding roller 42, which makes it easier to pick up the material from the repositioned winding roller 42.

[0048] In one embodiment, please refer to the appendix to the specification. Figure 1-2 As shown in Figures 4-6, the transmission assembly includes a first helical gear 45 disposed at one end of the rotating shaft 41, a second helical gear 46 disposed above and meshing with the first helical gear 45, a guide post 47 disposed above and connected to the second helical gear 46, and a guide rod 5 connected to the telescopic end of the telescopic assembly 23.

[0049] The guide post 47 is provided with a guide groove at the position corresponding to the guide rod 5. The guide groove includes a first guide groove 471 and a second guide groove 472 circumferentially distributed on the guide post 47. The second guide groove 472 is vertically opened on the guide post 47. The first guide groove 471 is inclinedly opened between two adjacent second guide grooves 472, with one end connected to the bottom of one of the second guide grooves 472 and the other end connected to the top of the other second guide groove 472. The depth of the end of the first guide groove 471 connected to the bottom of the second guide groove 472 exceeds the depth of the bottom of the second guide groove 472, and the depth of the end of the first guide groove 471 connected to the top of the second guide groove 472 is not greater than the depth of the top of the second guide groove 472.

[0050] The guide rod 5 moves along with the telescopic assembly 23. The telescopic assembly 23 first moves downwards and then upwards, causing the guide rod 5 to move downwards and then upwards synchronously. At this time, the guide rod 5 moves inside the guide groove. When the guide rod 5 moves downwards, the guide column 47 does not rotate; when the guide rod 5 moves upwards, the guide column 47 rotates. The rotation of the guide column 47 is supported by a support frame 48 provided on the guide column 47. That is, for every one extension stroke of the telescopic assembly 23, the guide column 47 rotates once. When the guide rod 5 moves inside the second guide groove 472, since the second guide groove 472 is vertically set, the guide rod 5 will limit the second guide groove 472 when it moves inside, so that the guide post 47 will not rotate when the guide rod 5 moves downward. Since the bottom height of the first guide groove 471 and the second guide groove 472 are both gradient surfaces, when the guide rod 5 enters the bottom of the first guide groove 471 from the bottom end of the second guide groove 472, the guide rod 5 will slide inside the first guide groove 471, thereby realizing the function of driving the guide post 47 to rotate.

[0051] In one embodiment, please refer to the appendix to the specification. Figure 1 and 3 As shown in Figure 4, the telescopic end of the telescopic component 23 is a lifting plate 6. The lifting plate 6 has a first inner groove 52 at the position corresponding to the guide rod 5. One end of the guide rod 5 is inserted into the first inner groove 52, and a first elastic element 51 is provided between the guide rod 5 and the bottom of the first inner groove 52.

[0052] The lifting plate 6 is provided with a guide sleeve 53 at the position corresponding to the guide rod 5, and the guide rod 5 slides through the guide sleeve 53.

[0053] The first elastic element 51 can push the guide rod 5 to always fit inside the guide groove, so that the end of the guide rod 5 always abuts against the guide post 47 when it moves; the guide sleeve 53 plays a role in stabilizing and supporting the guide rod 5, so that the guide rod 5 is relatively stable during the movement.

[0054] In one embodiment, please refer to the appendix to the specification. Figure 1-4 As shown, the cutting assembly cuts the insulating sheath by moving up and down; it also includes a clamping assembly disposed between the cutting assembly and the extruder 1, the clamping assembly comprising:

[0055] A round rod 24 is disposed on one side of the extruder 1 and located below the insulating sleeve, for supporting the insulating sleeve;

[0056] A clamping rod 22 is disposed above the round rod 24 and is used to cooperate with the round rod 24 to clamp the insulating sheath;

[0057] The extrusion rod 7 is connected to the cutting assembly and moves up and down together with the cutting assembly. The clamping rod 22 is rotatably mounted on the extrusion rod 7 and moves up and down together with the extrusion rod 7.

[0058] The cutting component has a second inner groove 73 at the position corresponding to the extrusion rod 7. The end of the extrusion rod 7 near the cutting component is at a right angle and is inserted into the second inner groove 73. The extrusion rod 7 can move up and down within the second inner groove 73.

[0059] A second elastic element 74 is provided between the top of the second inner groove 73 and the extrusion rod 7.

[0060] When the pressing rod 7 is driven downward synchronously by the lifting plate 6, the pressing rod 7 will press against the surface of the clamping rod 22. The clamping rod 22 will press against the surface of the insulating sleeve. Due to the presence of the round rod 24, the clamping rod 22 and the round rod 24 will cooperate to press the insulating sleeve tightly, thereby achieving clamping. When the pressing rod 7 moves down with the lifting plate 6, when the pressing rod 7 drives the clamping rod 22 to contact the insulating sleeve, due to the presence of the second elastic element 74, the pressing rod 7 will squeeze the second elastic element 74. When the lifting plate 6 continues to move down, the pressing rod 7 can already achieve the function of clamping the insulating sleeve. When the lifting plate 6 continues to move down and drives the first cutter 61 and the second cutter 61 to cooperate to complete the cutting work, the pressing rod 7 will clamp the insulating sleeve. During the clamping process, the pressing rod 7 will not break under the cooperation of the second elastic element 74. The notch 72 provides sufficient space for the extrusion rod 7 to move; the abutment rod 75 compresses the second elastic element 74 as the extrusion rod 7 moves upward, and when the abutment rod 75 is no longer subjected to extrusion force, the second elastic element 74 pushes the extrusion rod to reset.

[0061] In one embodiment, please refer to the appendix to the specification. Figure 1-2 As shown, it also includes an infrared sensor 3 and a controller. The output terminal of the infrared sensor 3 is connected to the controller. The infrared sensor 3 is used to monitor the thickness of the insulating sheath wound on the corresponding roller 42. The controller is electrically connected to the cutting assembly and each of the driving components and is used to control the start and stop of the cutting assembly and each of the driving components.
