Description

Technical Field

[0001] The present invention relates to the technical field of cable production equipment, and in particular to flexible flat cable production equipment and a production method thereof. Background Art

[0002] Flexible flat cable is a kind of cable made of PET insulation material and extremely thin tinned flat copper wire. It is soft, thin, and small in size. It has excellent bending resistance and can arbitrarily select the number and spacing of wires for easy connection. During the production process of flexible flat cable, a certain amount of talcum powder needs to be evenly coated between the insulation layer and the sheath layer to ensure that the insulation and sheath can be peeled off and have a certain peeling force.

[0003] The current cable powdering device adopts a sealed powder box filled with talcum powder. The cable that needs to be powdered is directly passed through one end of the sealed powder box through the traction of the extruder, so that a layer of talcum powder adheres to the surface of the wire. However, after the cable passes through the talcum powder, holes are easily formed in the talcum powder pile, resulting in uneven powder coating of subsequent cables. In addition, talcum powder stacked in the powder box for a long time is prone to cause agglomeration, which also affects the uniformity of cable powder coating. Summary of the invention

[0014] The present invention also provides a method for producing a flexible flat cable, comprising the following steps:

[0015] Step S1: First, the external traction mechanism is rotated to pass multiple cables through the inside of the conduit and enter the inside of the cable powder box to start the powdering operation;

[0016] Step S2, when the cable enters the cable powder box, the powder shaking mechanism is started to drive the talcum powder inside the cable powder box to shake left and right and spread flat, contact and coat the passing cable with powder, and at the same time, the talcum powder accumulated at the bottom of the cable powder box is dug out and poured to the top of the talcum powder pile;

[0017] Step S3: When the powder shaking mechanism is in operation, the cleaning mechanism will be triggered to operate synchronously, so as to perform rotational cleaning on the surface of the cable without dead angles;

[0018] Step S4: After the powdering is completed, when the cable passes through the interior of the second fixing plate, the scraping and regulating mechanism intercepts and scrapes away the excess talcum powder on the cable surface.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When in use, the driving motor drives the rotating shaft and the resisting protrusion to rotate continuously to resist the cable powder box, and the compression rod and the resisting spring cooperate to rebound, so that when the cable is powdered, the cable powder box can drive the internal talcum powder to shake left and right and spread flat, ensuring that it is not easy to form holes in the talcum powder pile after multiple cables pass through the talcum powder inside the powder box, ensuring that the subsequent cables are evenly powdered, when the cable powder box is in reciprocating sliding vibration, it will drive one side of the ratchet and the limit rack to rotate in mesh, so that the multiple rotating rods drive the transmission wheel and the transmission belt to rotate synchronously in one direction, and cooperate with the arc shape of multiple limit plates, so that the transmission belt drives the multiple limit plates to dig and transmit the talcum powder accumulated at the bottom of the cable powder box, and dump it to the top of the talcum powder pile, thereby avoiding the waste caused by the long-term accumulation and agglomeration of the talcum powder at the bottom of the cable powder box, and at the same time, when the limit plate dumps the dug talcum powder at the top, the talcum powder can fall, so that the overall powdering effect is better;

[0021] 2. When multiple cables pass through the conduit and enter the cable powder box for powdering, the surface of the cable will contact the multiple arc plates and bristles inside the conduit. At the same time, the cable powder box will drive the positioning rack to contact the gear ring during reciprocating motion, driving the gear ring to rotate back and forth, thereby driving the conduit and the multiple arc plates inside and the bristles to rotate and clean the surface of the cable, so that the adhered impurities on the entire outer circumference of the cable can be removed by friction, reducing the cleaning dead corners and ensuring the cleanliness of the cable surface, thereby improving the uniformity of talcum powder adhesion during powdering. At the same time, with the setting of the suction tube, vacuum cleaner and collection box, some impurities removed by friction can be sucked and collected. Through the coordinated installation of the compression spring and the limit rod, the bristles can always contact the outer surface of the cable to ensure the cleaning effect and expand the scope of application. At the same time, through the rapid contact and friction between the bristles and the cable surface, a certain amount of static electricity is generated on the cable surface, which increases the adsorption force of the cable surface and can improve the subsequent powdering and wrapping effect to a certain extent.

[0022] 3. When multiple cables are pulled out after being powdered through the cable powdering box, the excess talcum powder on the cable surface can be intercepted and scraped off by the expanded annular airbag, thereby ensuring the uniformity of the powdering, avoiding waste of carrying and discharge, and ensuring the use effect. When the diameter of the cable to be powdered changes, the roller rod, air collecting cylinder, piston block, tension spring and air guide tube are installed in coordination, so that the device can automatically adjust the expanded inner diameter of the annular airbag, so as to scrape and clean the excess talcum powder on the surface of cables of different diameters. The overall application range is wide and the use is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 11 The present invention provides a technical solution: a flexible flat cable production device, comprising a workbench 1, a cable powder box 2 is slidably installed on the top of the workbench 1, and slide grooves 3 are penetrated on both sides of the cable powder box 2, and the interiors of the two slide grooves 3 are respectively slidably engaged with fixed plates 1 4 and fixed plates 2 6, and sealing curtains 7 are sealed and installed between the two sides of the fixed plates 1 4 and the fixed plates 2 6 and the inner walls of one side of the slide groove 3, and the bottom ends of the fixed plates 1 4 and the fixed plates 2 6 are fixedly installed on the outside of one side of the top of the workbench 1 through a bracket, and a plurality of conduits 5 are rotatably engaged and installed in the interior of the fixed plate 1 4 at equal intervals, and a powder shaking mechanism 8, which is arranged on the outside of one side of the cable powder box 2; the powder shaking mechanism 8 includes a rotating shaft 801 and a contact protrusion 803, and the rotating shaft 801 is symmetrically and longitudinally rotatably installed on one side of the top of the workbench 1, and the top of the rotating shaft 801 is penetrated and fixed with a contact protrusion 803; a cleaning mechanism 9, which is arranged on the outside of one side of the conduit 5.

[0037] In this embodiment, the flexible flat cable production equipment mainly includes a workbench 1, a cable powder box 2, a chute 3, a powder shaking mechanism 8 and a cleaning mechanism 9. When the flexible flat cable production equipment provided by this scheme is actually used, first, the existing external cable traction mechanism is rotated to pass multiple cables through the inside of the conduit 5 into the cable powder box 2 to start the powdering operation. When the cables enter the cable powder box 2, the powder shaking mechanism 8 is started to run, thereby driving the talcum powder inside the cable powder box 2 to shake left and right and spread flat, and the passing cables are contacted and powdered to ensure that it is not easy for multiple cables to form holes in the talcum powder pile after passing through the talcum powder inside the powder box 2, so as to ensure that the subsequent cables passing through are evenly powdered. At the same time, the talcum powder accumulated at the bottom of the cable powder box 2 can be dug and poured to the top of the talcum powder pile. When the powder shaking mechanism 8 is in operation, the cleaning mechanism 9 will be triggered to run synchronously, so as to perform a dead-angle rotation cleaning on the surface of the cable, and the overall use effect is good.

[0038] By connecting and installing sealing curtains 7 between both sides of the fixed plate 1 4 and the fixed plate 2 6 and the inner wall of one side of the slide groove 3, when the cable powder box 2 moves left and right, no holes will appear on both sides of the fixed plate 1 4 and the fixed plate 2 6, which will be blocked by the sealing curtains 7, thereby avoiding talcum powder leakage and ensuring the overall use effect.

[0039] In some embodiments, the powder shaking mechanism 8 also includes a chain sprocket transmission group 802, a drive motor 804 and a compression rod 805. A chain sprocket transmission group 802 is installed between the outer sides of the bottom ends of the two rotating shafts 801 for transmission. A drive motor 804 is installed on the bottom end of the workbench 1, and the output shaft of the drive motor 804 is coaxially fixed with the bottom end of one of the rotating shafts 801. A compression rod 805 is symmetrically and laterally fixed on the side of the cable powder box 2 away from the rotating shaft 801, and one end of the compression rod 805 is fixed on the outer wall of one side of the workbench 1; the powder shaking mechanism 8 also includes a resistance spring 806, a rotating rod 807, a chain sprocket transmission group 808, a ratchet 809 and a limiting rack 8010. The outside of the compression rod 805 is penetrated by a resistance spring 806, and the two ends of the resistance spring 806 are respectively embedded and fixed on the outside of one side of the workbench 1 and the outside of one side of the cable powder box 2.

[0040] Combination Figure 1 , Figure 3 and Figure 6 As shown, after the cable enters the interior of the cable powder box 2, a driving motor 804 on one side is started at this time, and through the rotation of the output shaft of the driving motor 804 and the transmission installation of the chain sprocket transmission group 802, the rotating shafts 801 on both sides of the top and the resistance protrusions 803 start to rotate synchronously. The resistance protrusions 803 will continuously resist one side of the cable powder box 2 during rotation, so that the cable powder box 2 moves, and at the same time cooperate with the resistance reset rebound of the compression rod 805 on one side and the resistance spring 806, so that the cable powder box 2 can rebound when it is not resisted by the resistance protrusion 803, so that the cable powder box 2 can reciprocate and shake at the top of the workbench 1 when the driving motor 804 is started, so that when the cable is powdered, the cable powder box 2 can drive the internal talcum powder to shake left and right and spread flat, ensuring that it is not easy to form holes in the talcum powder pile after multiple cables pass through the talcum powder inside the powder box 2, and ensuring that the subsequent cables passing through are evenly coated with powder.

[0041] In some embodiments, a rotating rod 807 is provided at the internal corner of the cable powder box 2, and both ends of the rotating rod 807 are rotatably installed on the outside of one side of the cable powder box 2, and a chain sprocket transmission group 808 is installed between the outside of one end of the rotating rod 807, and a ratchet 809 is installed on the outside of one end of one of the rotating rods 807, and a limit rack 8010 is fixedly engaged and installed at the bottom end of the ratchet 809, and the limit rack 8010 is installed on the outside of the top side of the workbench 1 through a bracket; the powder shaking mechanism 8 also includes a transmission wheel 8011, a transmission belt 8012 and a limit plate 8013, and a plurality of transmission wheels 8011 are fixedly installed on the outside of the rotating rod 807 at equal intervals, and a transmission belt 8012 is transmission-connected between the outsides of the transmission wheels 8011 on the same longitudinal section, and a limit plate 8013 is fixedly installed on the outside of one side of the transmission belt 8012 at equal intervals, and the limit plate 8013 is arc-shaped.

[0042] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when the cable powder box 2 is in reciprocating sliding vibration, it will drive the ratchet wheel 809 on one side to move synchronously, and cooperate with the ratchet wheel 809 to mesh and rotate with the limit rack 8010, so that the ratchet wheel 809 will rotate unidirectionally, thereby causing the ratchet wheel 809 to drive a rotating rod 807 to rotate, and cooperate with the transmission connection of the chain sprocket transmission group 808, so that multiple rotating rods 807 can rotate synchronously, thereby driving the transmission wheel 8011 and the transmission belt 8012 to rotate synchronously in one direction, and cooperate with the arc shape setting of multiple limit plates 8013, so that the transmission belt 8012 drives multiple limit plates 8013 to dig and transport the talcum powder accumulated at the bottom of the cable powder box 2, and dump it to the top of the talcum powder pile, thereby avoiding the waste caused by the long-term accumulation and agglomeration of talcum powder at the bottom of the cable powder box 2, and at the same time, when the limit plate 8013 dumps the dug talcum powder at the top, the talcum powder can fall, so that the overall powdering effect is better.

[0043] In some embodiments, the cleaning mechanism 9 includes a gear ring 901, a positioning rack 902, an arc plate 903 and bristles 904. The gear ring 901 is fixed to the outside of one side of the conduit 5. A positioning rack 902 is fixed to the outside of the cable passing through the powder box 2 close to the gear ring 901, and one side of the positioning rack 902 is meshed and connected with one side of the gear ring 901. The inside of the conduit 5 is surrounded by arc plates 903 at equal angles, and the outside of the arc plates 903 close to the center of the conduit 5 is adhered and fixed with bristles 904; the cleaning mechanism 9 also includes a limiting rod 905, a compression spring 906 and a collecting box 9010. The limiting rod 905 is symmetrically fixed to the side of the arc plate 903 away from the bristles 904, and one end of the limiting rod 905 penetrates and is slidably installed on the guide. On the outside of one side of the tube 5, a compression spring 906 is installed through the outside of one side of the limit rod 905, and the two ends of the compression spring 906 are respectively embedded on the outside of one side of the arc plate 903 and the inner wall of one side of the tube 5, and a collection box 9010 is fixed on the outside of the side of the workbench 1 close to the tube 5; the cleaning mechanism 9 also includes a support tube 907, a suction tube 908 and a vacuum cleaner 909, the top of the collection box 9010 is connected and installed with the vacuum cleaner 909, and the input end of the vacuum cleaner 909 is connected and fixed with the support tube 907, and the suction tube 908 is arranged at the outer edge of one side of the tube 5, and the output end of the suction tube 908 is connected and installed with the inside of one side of the support tube 907, and the input end of the suction tube 908 is facing the inside of one side of the tube 5.

[0044] Combination Figure 7 and Figure 8 As shown, when the cable powder box 2 reciprocates, it will drive the positioning rack 902 installed on one side to reciprocate synchronously. Through the reciprocating motion of the positioning rack 902, the multiple gear rings 901 meshing at the bottom are driven to reciprocate synchronously, thereby driving the conduit 5 and the multiple arc plates 903 inside it to reciprocate, so that the multiple arc plates 903 and the bristles 904 on the inner wall can rotate and clean the surface of the cable, thereby frictionally removing adherent impurities on the entire outer circumferential surface of the cable, reducing cleaning dead corners, ensuring the cleanliness of the cable surface, and thereby improving the uniformity of talcum powder adhesion during powdering.

[0045] During rotary cleaning, the vacuum cleaner 909 on one side is started synchronously, and through the conductive installation of the suction tube 908 and the support tube 907, some impurities removed by the cleaning brush can be sucked into the interior of the collection box 9010 through the vacuum cleaner 909, thereby ensuring the overall cleaning effect. At the same time, the bristles 904 are in rapid contact and friction with the cable surface, so that a certain amount of static electricity is generated on the cable surface, which increases the adsorption force of the cable surface and can improve the subsequent powder wrapping effect to a certain extent.

[0046] When in use, the compression spring 906 and the limit rod 905 are installed in coordination so that the bristles 904 can always be in contact with the outer surface of the cable to ensure the cleaning effect. At the same time, when encountering cables of different diameters, the compression and rebound of the compression spring 906 can drive the arc plate 903 to move and change synchronously, so as to adaptively adjust the diameter of the cable, thereby expanding the overall scope of application.

[0047] In some embodiments, a scraping regulating mechanism 10 is disposed on the outside of one side of the conduit 5, and the scraping regulating mechanism 10 includes a roller rod 1001, a gas collecting cylinder 1002, a piston block 1003 and a tension spring 1004. A roller rod 1001 is longitudinally disposed at the bottom end of one side of the conduit 5, and a gas collecting cylinder 1002 is fixed on one side of the bottom end of the workbench 1 close to the roller rod 1001. The bottom end of the roller rod 1001 is slidably installed inside one side of the gas collecting cylinder 1002, and a piston block 1003 is fixed at the through end of the bottom end of the roller rod 1001, and the piston block 1003 is slidably sealed with the inside of the gas collecting cylinder 1002, and the roller rod 1001 is located at the gas collecting cylinder 1002. A tension spring 1004 is installed and sleeved through the outside of one side of the interior of the cylinder 1002, and the two ends of the tension spring 1004 are respectively embedded and installed inside the top wall of the air collecting cylinder 1002 and the top side of the piston block 1003; the scraping and regulating mechanism 10 also includes an air guide tube 1005, a through hole 1006 and an annular air bag 1007, the bottom end of the air collecting cylinder 1002 is connected and installed with the air guide tube 1005, the inside of one side of the fixing plate 6 close to the catheter 5 is penetrated by a through hole 1006, and the annular air bag 1007 is fixed on the inner wall of the through hole 1006, and one end of the air guide tube 1005 is connected and installed inside one side of the annular air bag 1007.

[0048] Combination Fig. 9 , Fig.10 and Fig.11 As shown, when the cable passes through the through hole 1006 inside the fixing plate 6 after powdering, the excess talcum powder adhering to the cable surface will be scraped off by one side of the annular air bag 1007 inflated inside the through hole 1006, so that the excess talcum powder on the cable surface can be intercepted and scraped off, thereby ensuring the uniformity of powdering, avoiding discharge waste, and ensuring the use effect.

[0049] When cables of different diameters are powdered, the outer wall of the cable will come into contact with the top roller end of the roller rod 1001, so that the roller rod 1001 drives the piston block 1003 to move, thereby driving the tension spring 1004 to deform, so that the internal gas of the annular airbag 1007 can be extracted or squeezed in, thereby automatically adjusting the expanded inner diameter of the annular airbag 1007, so that excess talcum powder on the surface of cables of different diameters can be scraped off and cleaned. The overall application range is wide, the use is convenient, and self-adjustment can be achieved.

[0050] The present invention also provides a method for producing a flexible flat cable, comprising the following steps:

[0051] Step S1, firstly, the external traction mechanism is rotated to make multiple cables pass through the inside of the conduit 5 and enter the inside of the cable powder box 2 to start the powdering operation;

[0052] Step S2, when the cable enters the cable powder box 2, the powder shaking mechanism 8 is started to run, so as to drive the talcum powder inside the cable powder box 2 to shake left and right and spread flat, contact and coat the passing cable with powder, and at the same time, the talcum powder accumulated at the bottom of the cable powder box 2 is dug out and poured to the top of the talcum powder pile;

[0053] Step S3, when the powder shaking mechanism 8 is in operation, the cleaning mechanism 9 will be triggered to operate synchronously, so as to perform rotational cleaning on the surface of the cable without dead angles;

[0054] Step S4, after the powdering is completed, when the cable passes through the interior of the second fixing plate 6, the scraping and regulating mechanism 10 intercepts and scrapes away the excess talcum powder on the cable surface.
