Description
Technical Field
[0001] The present invention relates to the technical field of core production, and specifically to a preheating device for preheating a core to improve the adhesion degree. Background Art
[0002] Core preheating is an important link in the production process of wire and cable. It is of great significance for improving production quality, increasing production efficiency, and extending the service life of the cable, etc. Through core preheating, moisture in the material can be removed, insulation adhesion can be increased, and material properties can be improved, thereby ensuring the stability of the product.
[0003] For example, the patent application with the authorization announcement number CN209216646U discloses a cable preheating device, including a base and a box body for preheating the cable. A heating unit is arranged inside the box body. The box body is a shell with an open surface. The open surface is parallel to the length direction of the base and perpendicular to the width direction of the base. At least one wire storage wheel for winding the cable is arranged inside the box body. The axis line of the wire storage wheel is parallel to the width direction of the base. A bracket corresponding to the wire storage wheel in number is arranged on the base of the open surface. The bracket penetrates into the box body and is used to support the wire storage wheel. Two side walls of the box body adjacent to the open surface respectively have a wire guiding groove. One ends of the two wire guiding grooves respectively extend to the open surface, and the wire guiding groove communicates with the inside of the box body. At least one group of linear slide rails is arranged on the base. The extending direction of the linear slide rail is parallel to the width direction of the base. The box body is slidably connected to the linear slide rail.
[0004] However, there are still some problems in the above application. When using the preheating box to preheat the core, a barrel-type preheater, a hot air blower or a warm air blower is used to preheat the core placed in it. During the heating-up process of the above cable preheating device, gas flow will occur, which will cause contact between the gas and the core, and the winding part for winding the core rotates, resulting in the cable being unwound again after winding, causing the cable to be messy.
[0005] Therefore, how to avoid reverse winding of the cable is a problem to be solved at present. Summary of the Invention
[0006] The present invention provides a preheating device for preheating a core to improve the adhesion degree to solve the above problems existing in the prior art.

[0008] A preheating chamber for preheating the core placed in the preheating chamber;
[0009] A workbench, located within the heating area of the preheating chamber;
[0010] Two rotating units, arranged on the workbench, used for adjusting the position of the core;
[0011] A winding unit and a winding part connected to the winding unit. The winding unit is used to drive the winding part to rotate, and the winding unit is used to wind the core;

The winding part is located on one of the clamping seats;
[0037] By adjusting the position of the clamping seat on the limiting plate, the distance between the clamping seats is changed, so as to complete the fixing work of the driving shaft.
[0038] Furthermore, an oil injection part is also provided on the driving shaft;
[0039] The axes of the two injection holes intersect, and the injection hole with a preset angle between its axis and the axis of the driving shaft is the oil injection port of the oil injection part;

[0041] Furthermore, there is a predetermined oil passage between adjacent guide plates;

The moving winding assembly can drive the driving part to rotate. The working driving part can drive the pawl to move, so that the abutting teeth move in the placement groove. At this time, the driving part rotates clockwise. When the driving part rotates counterclockwise, at this time, the free end of the abutting tooth abuts against one side of the placement groove, which causes the pawl to move towards the driving seat, increasing the deformation amount of the elastic piece and making the pawl in a clamped state. At this time, the driving seat can be driven to rotate counterclockwise under the drive of the winding assembly; when the cable is subjected to an external force causing the driving seat to rotate in the reverse direction, that is, after part of the winding work is completed, at this time, the winding assembly stops working, and the generated hot air will blow the wire core, resulting in the reverse rotation of the driving seat. The reversely moving driving seat will still make the pawl move towards the driving seat, making the pawl in a clamped state. At this time, the pawl can prevent the driving seat from rotating, and the driving seat stops reversing, avoiding the rewinding of the wound cable and the mess of the cable. At the same time, it can also ensure the smooth progress of the wire core preheating work. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed embodiments
[0057] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be made with reference to the accompanying drawings of the specification.
[0058] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0059] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.
[0060] The present invention discloses a preheating device for preheating a wire core to improve the adhesion. Referring to Figures 1-12 , including:
[0061] Preheating chamber 1 is used to preheat the wire core placed in the preheating chamber 1 to increase the temperature of the wire core; workbench 2 is located in the heating area of the preheating chamber 1; there are two rotating units 4, which are arranged on the workbench 2 and used to adjust the position of the wire core, a winding unit 5, and a winding part 6 connected to the winding unit 5. The winding unit 5 is used to drive the winding part 6 to rotate, and the winding unit 5 is used to wind the wire core; the winding unit 5 includes a winding assembly arranged on the rotating unit 4, a driving part 54 connected to the winding assembly, a driving seat 55 connected to the driving part 54, and a driving shaft 56 arranged on the driving seat 55 and connected to the rotating unit 4; the winding part 6 is connected to the driving shaft 56; through the combined use of the rotating unit 4 and the winding unit 5 provided, not only can the wire core be preheated during the winding process, but after completing part of the winding work for different wire core materials, the winding assembly can also stop winding, and then the barrel-type preheater or hot air blower or heater in the preheating chamber 1 can continuously heat a part of the wire core to complete the preheating work of the wire core.
[0062] In a further embodiment, in the prior art, during the use of the barrel-type preheater or hot air blower or heater, when the winding assembly stops winding, the barrel-type preheater or hot air blower or heater can preheat the wire core located on the supporting unit 3 to increase the temperature of the wire core. However, since in the prior art, the temperature is increased in the form of hot air during the preheating work, the hot air will directly contact the wire core, which will cause the wire core to deform, resulting in the wire core on the winding part 6 rotating in the opposite direction of the winding direction, thus causing the wire core to unwind and making the wire core messy.
[0063] To solve the above problems, a driving part 54 is provided in the device. The driving part 54 is of an annular structure and is provided with a plurality of through holes in the circumferential direction. The driving part 54 includes a pawl 543 passing through the through holes and rotatably connected to the inner wall of the through holes, an abutting tooth 544 arranged on the pawl 543, and an elastic piece 545 arranged on the outer wall of the driving part 54. The free end of the abutting tooth 544 points to the driving seat 55. The driving seat 55 is of a columnar structure, and a plurality of placing grooves are arranged on its curved surface. The free ends of the abutting teeth 544 are all located in the placing grooves. There is a predetermined angle between the free end of the abutting tooth 544 and the free end of the pawl 543. One end of the elastic piece 545 abuts against the abutting tooth 544 and there is a predetermined distance from the connection between the abutting tooth 544 and the pawl 543. The winding assembly includes a winding motor 51 fixedly installed on the rotating unit 4, a driving gear 52 connected to the output end of the winding motor 51, and a coaxial gear 53 meshing with the driving gear 52. The driving part 54 includes a movable seat 541 arranged on the rotating unit 4, and a driven gear 542 sleeved on the movable seat 541. The coaxial gear 53 includes a small gear meshing with the driving gear 52, a large gear meshing with the driven gear 542, and a concentric shaft for connecting the small gear and the large gear. The through holes are arranged on the movable seat 541. When the winding assembly works for normal winding of the wire core, the moving winding assembly drives the driving part 54 to rotate. At this time, the winding motor 51 starts to work. The moving winding motor 51 can drive the driving gear 52 to rotate, and then the moving driving gear 52 can drive the coaxial gear 53 to rotate. Further, the moving coaxial gear 53 drives the driving part 54 to rotate through the driven gear 542 in the driving part 54. Then the working driving part 54 can drive the pawl 543 to move, so that the abutting tooth 544 moves in the placing groove. At this time, the driving part 54 rotates clockwise. When the driving part 54 rotates counterclockwise, at this time, the free end of the abutting tooth 544 abuts against one side surface of the placing groove, which causes the pawl 543 to move towards the driving seat 55, increases the deformation amount of the elastic piece 545, and makes the pawl 543 in a clamping state. At this time, the driving seat 55 can be driven to rotate counterclockwise under the drive of the winding assembly. When the cable is subjected to an external force and causes the driving seat 55 to rotate in the reverse direction, that is, after part of the winding work is completed, at this time, the winding assembly stops working. The generated hot air will blow the wire core, which causes the driving seat 55 to rotate in the reverse direction. The reversely moving driving seat 55 still makes the pawl 543 move towards the driving seat 55, making the pawl 543 in a clamping state. At this time, the pawl 543 can prevent the driving seat 55 from rotating, and the driving seat 55 stops reversing, avoiding the re-unwinding of the wound cable, avoiding the mess of the cable, and also ensuring the smooth progress of the preheating work of the wire core. In this process, the counterclockwise direction is the winding direction of the wire core.
[0064] In a further embodiment, since the wire core itself has a certain weight, in order to ensure the preheating efficiency of the wire core in the preheating chamber 1, the wire core is placed in the preheating chamber 1 in a serpentine manner, increasing the placement length of the wire core in a unit space. However, this method will cause the wire core to deform under the influence of its own weight, thus causing the rotation of the winding part 6.
[0065] To solve the above problems, a support unit 3 for supporting the wire core is further provided on the workbench 2; the support unit 3 includes a driving component 31 fixedly installed on the workbench 2, a support frame 32 connected to the output end of the driving component 31, and four support parts arranged on the support frame 32; the support part includes a locking plate 33 fixedly installed on the support frame 32, a connecting rod 34 arranged on the locking plate 33, a template seat 35 connected to the connecting rod 34, and two limiting parts 36 symmetrically arranged on the template seat 35; wherein the limiting part 36 includes a limiting wheel 362 movably connected to the template seat 35, connecting plates 361 symmetrically arranged on both sides of the limiting wheel 362, and a limiting protrusion 363 arranged on one of the connecting plates 361; there is a predetermined gap between the limiting protrusion 363 and the limiting wheel 362; two support parts are taken as a group, there is a predetermined distance between the two groups of support parts, and in the image corresponding to the orthographic projection thereof, there are established gaps between the four support parts. During the preheating work, one end of the wire core passes through the gap between the limiting protrusion 363 and the limiting wheel 362 in one of the support parts, and then bypasses the next support part in turn, so that the wire core presents an S shape between the support parts, thus increasing the length of the wire core while completing the support work of the wire core and ensuring the preheating efficiency.
[0066] In a further embodiment, the driving assembly 31 includes a fixed seat 311 fixedly mounted on the workbench 2, a driving motor 312 disposed on the fixed seat 311, a driving lead screw 313 connected to the output end of the driving motor 312, a transmission member 314 sleeved on the driving lead screw 313, and an adjusting frame 315 connected to the transmission member 314; the adjusting frame 315 is connected to the support frame 32; the wire core sequentially bypasses the four supporting portions, and the wire core is in an S shape; two limiting motors 37 are provided on the template seat 35 on the first supporting portion connected to the wire core, and the output end of the limiting motor 37 is connected to a limiting member 36 on the template seat 35; the connecting plate 361 is in a water droplet shape, and a predetermined angle exists between the small head directions of the connecting plates 361 of the two limiting wheels 362 on the same template seat 35; when the winding work needs to be carried out, at this time, the driving motor 312 starts to work, and the moving driving motor 312 can drive the driving lead screw 313 to start rotating, so that the rotating driving lead screw 313 can drive the transmission member 314 to start working, so that the moving transmission member 314 can drive the adjusting frame 315 to start moving, so that the supporting portion can move along the axial direction of the winding portion 6, and at the same time, the winding portion 6 can drive the wire core to be wound, and the winding work of the wire core is completed under the cooperation of the two; at the same time, the limiting motor 37 in the device can also adjust the angle between the two limiting members 36 on the first supporting portion connected to the wire core, which can not only complete the tightening work of the wire core to prevent the wire core from deforming due to its own weight, but also reduce the pressure on the wire core to avoid the wire core from breaking due to excessive pressure.
[0067] The rotating unit 4 includes a rotating motor 41 and a transmission shaft 42 disposed on the workbench 2, driving wheels 43 respectively disposed at the output end of the rotating motor 41 and one end of the transmission shaft 42, a transmission belt 44 for connecting the two driving wheels 43, a rotating seat 48 disposed at the other end of the transmission shaft 42, and a transmission frame 45 disposed on the rotating seat 48; when the rotating motor 41 starts to rotate, the moving rotating motor 41 can drive the rotating seat 48 to rotate through the provided driving wheels 43 and the transmission belt 44, and the moving rotating seat 48 can drive the transmission frame 45 to start working, so as to adjust the position of the clamping seat 47, thereby adjusting the angle between the axis of the winding portion 6 located on the clamping seat 47 and the ground, and adjusting the tightness of the wire core to avoid the wire core from being too loose.
[0068] Two limiting plates 46 are symmetrically arranged on the transmission frame 45. A plurality of limiting holes are provided on the limiting plates 46, and a clamping seat 47 is sleeved on the limiting plates 46. Among them, two injection holes are provided on the clamping seat 47 close to the support unit 3. The axis of one injection hole coincides with the axis of the drive shaft 56, and there is a preset angle between the axis of the other injection hole and the axis of the drive shaft 56. The winding part 6 is located on one of the clamping seats 47. By adjusting the position of the clamping seat 47 on the limiting plate 46, the distance between the clamping seats 47 is changed, so as to complete the fixing work of the drive shaft 56. By providing two injection holes and connecting them, a Y-shaped oil injection cavity is formed, and then oil injection work can be carried out through this oil injection cavity to ensure the smooth operation of the winding unit 5.
[0069] An oil injection part 57 is further provided on the drive shaft 56. The axes of the two injection holes intersect. The injection hole with a preset angle between its axis and the axis of the drive shaft 56 is the oil injection port of the oil injection part 57. The oil injection part 57 includes a sleeve 571 sleeved on the drive shaft 56, a plurality of guide plates 573 located between the sleeve 571 and the clamping seat 47, and a mounting seat 572 sleeved on the sleeve 571. There is a predetermined oil passage between adjacent guide plates 573. The guide plates 573 have a predetermined radian and the width direction of the guide plates 573 gradually decreases along the injection direction of the lubricating oil, so that the width of the oil passage gradually increases. A plurality of oil leakage holes are opened at the bottom of the mounting seat 572, so that the lubricating oil can flow into other areas on the drive shaft 56. When carrying out oil injection work, the lubricating oil flows into the gap between the guide plates 573 along the injection hole, and as the distance between adjacent guide plates 573 increases, the coverage area of the lubricating oil is increased. Then the lubricating oil can abut against the mounting seat 572 and flow along the oil leakage holes on the mounting seat 572 to other areas on the drive shaft 56, so as to complete the injection work of the lubricating oil, reduce the friction force it receives during rotation, and ensure the normal operation of the device.
[0070] Working principle description: When preheating the wire core is required, first, the position of the clamping seat 47 in the length direction of the limit plate 46 needs to be adjusted. Then, after installing the driving seat 55 in the established position, the driving shafts 56 are respectively located on the two clamping seats 47, and the abutting teeth 544 are located in the grooves on the driving seat 55. Then, when performing the preheating work, one end of the wire core passes through the gap between the limit protrusion 363 and the limit wheel 362 in one of the support parts, and then successively bypasses the next support part, making the wire core present an S shape between the support parts, thus increasing the length of the wire core while completing the support work for the wire core and ensuring the preheating efficiency. Then, the tightness of the wire core is adjusted. At this time, the rotating motor 41 starts to rotate. The moving rotating motor 41 can drive the rotating seat 48 to rotate through the driving wheel 43 and the transmission belt 44 provided. The moving rotating seat 48 can drive the transmission frame 45 to start working, and further can adjust the position of the clamping seat 47, thereby adjusting the angle between the axis of the winding part 6 located on the clamping seat 47 and the ground, adjusting the tightness of the wire core, and avoiding the wire core from being too loose. Then, when the winding work needs to be carried out, at this time, the driving motor 312 starts to work. The moving driving motor 312 can drive the driving lead screw 313 to start rotating, so that the rotating driving lead screw 313 can drive the transmission part 314 to start working. Thus, the moving transmission part 314 can drive the adjusting frame 315 to start moving, so that the support part can move along the axis direction of the winding part 6, and at the same time, the winding part 6 can drive the wire core to be wound, and the winding work of the wire core is completed under the cooperation of the two. When the winding assembly works, the moving winding assembly drives the driving part 54 to rotate. At this time, the winding motor 51 starts to work. The moving winding motor 51 can drive the driving gear 52 to rotate. Then, the moving driving gear 52 can drive the coaxial gear 53 to rotate. Furthermore, the moving coaxial gear 53 drives the driving part 54 to rotate through the driven gear 542 in the driving part 54. Then, the working driving part 54 can drive the pawl 543 to move, so that the abutting tooth 544 moves in the placement groove. When the driving part 54 rotates counterclockwise, at this time, the free end of the abutting tooth 544 abuts against one side surface of the placement groove, thereby causing the pawl 543 to move towards the driving seat 55, increasing the deformation amount of the elastic piece 545, and making the pawl 543 in a clamped state. At this time, the driving seat 55 can be driven to rotate counterclockwise under the drive of the winding assembly.When the cable is subjected to external force causing the driving seat 55 to rotate in the reverse direction, that is, after partial winding work is completed, the winding assembly stops working at this time. The hot air generated will blow the wire core, resulting in the reverse rotation of the driving seat 55. The driving seat 55 moving in the reverse direction will still cause the pawl 543 to move towards the driving seat 55, making the pawl 543 in a clamped state. At this time, the pawl 543 can prevent the driving seat 55 from rotating, and the driving seat 55 stops reversing, avoiding the rewinding of the wound cable and the mess of the cable. At the same time, it can also ensure the smooth progress of the wire core preheating work. In this process, the counterclockwise direction is the winding direction of the wire core; when refueling, the lubricating oil flows into the gap between the guide plates 573 along the injection hole, and as the distance between adjacent guide plates 573 increases, the coverage area of the lubricating oil increases. Then the lubricating oil can abut against the mounting seat 572 and flow to other areas on the drive shaft 56 along the oil leakage holes on the mounting seat 572, thus completing the injection work of the lubricating oil and reducing the friction force it receives during rotation to ensure the normal operation of the device; during the winding work process, the barrel-type preheater or hot air blower or heater in the preheating box can increase the temperature in the preheating box, and then can preheat the wire core to improve its adhesion.;
