Description

Technical Field

[0001] The present invention relates to the technical field of coating machines, in particular to a coating machine for preparing paper-covered copper rectangular wires. Background Art

[0002] Paper-wrapped copper flat wire refers to a wire whose insulation layer is wrapped cable paper. Paper-wrapped copper flat wire has good insulation properties and mechanical strength and can withstand higher voltages and currents. A coating machine is required in the production process of paper-wrapped copper flat wire. Traditional coating machines usually use a combined coating, winding and traveling method to coat copper flat wire in order to improve coating efficiency.

[0003] Since different widths of insulating paper need to be used for wrapping in different situations, the current wrapping machine is not convenient for adjusting the travel speed of the copper flat wire according to the width of the insulating paper when wrapping the copper flat wire, which may cause gaps or accumulation of the insulating paper when winding on the copper flat wire. In addition, the tensile strength of insulating paper of different widths is different, and the existing wrapping machine is difficult to adjust the pulling force according to the width of the insulating paper, which may cause the insulating paper to be torn due to excessive tension or to be wound too loosely due to insufficient tension. This is not conducive to the device adapting to insulating paper of different widths, has low applicability, and has poor wrapping effect. Summary of the Invention

DETAILED DESCRIPTION

[0036] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0037] Example 1: A coating machine for preparing paper-covered rectangular copper wire, such as Figures 1-16 Shown, including: Base 1; The housing 2 is connected to the base 1 by bolts. A feed port and a discharge port are respectively provided on both sides of the housing 2. A copper flat wire 0 passes through the feed port and the discharge port of the housing 2. The motor 3 is mounted on the bottom of the feed port side of the housing 2, and the output shaft of the motor 3 is rotatably connected to the housing 2; The covering mechanism is used to cover the copper flat wire 0 and is provided on the housing 2 and the motor 3; The glue coating component is used to apply glue to the surface of the copper flat wire 0 before coating, and is provided on the housing 2; A compacting component, used to flatten the four sides and four corners of the coated copper flat wire 0, is provided on the housing 2; The driving mechanism is used to drive the copper flat wire 0 to move, and is provided on the motor 3, the housing 2 and the compression assembly.

[0038] The wrapping mechanism includes: a rotating disk 41 rotatably connected to the outer shell 2, and the flat copper wire passes through the rotating disk 41; a ring gear 42 connected to the rotating disk 41 through a keyway; a driving gear 43 connected to the output shaft of the motor 3 through a flat key and meshing with the ring gear 42; two fixed rods 44 symmetrically connected to the rotating disk 41 by bolts; a tube shaft 45 is welded on the two fixed rods 44, and a thread groove is opened on the tube shaft 45, and the axes of the two tube shafts 45 are symmetrically inclined to the copper flat wire 0; locking blocks 46 are threadedly connected to the thread grooves of the two tube shafts 45; a wrapping disk 47 is rotatably connected to the two tube shafts 45, and the locking block 46 is used to limit the wrapping disk 47 to the tube shaft 45; insulating paper 48 is wound around the two wrapping disks 47, and one end of the two insulating papers 48 is arranged on the copper flat wire 0, and the insulating paper 48 is used to wrap the surface of the copper flat wire 0.

[0039] The glue coating assembly includes: a glue delivery rack 51 connected to the shell 2 by bolts, and the top of the glue delivery rack 51 passes through the shell 2; a sponge block 52 arranged in the glue delivery rack 51 and in contact with the surface of the copper flat wire 0, used to apply insulating glue to the surface of the copper flat wire 0.

[0040] The compaction assembly includes: a limit frame 61 welded to the inner wall of the outer shell 2; two side pressure rollers 62 and two positive pressure rollers 63 rotatably connected to the limit frame 61, the side pressure rollers 62 and the positive pressure rollers 63 are respectively used to compact and flatten the four sides and four corners of the coated copper flat wire 0, and the positive pressure rollers 63 are also used to drive the copper flat wire 0 to move forward.

[0041] The positive pressure roller 63 is made of rubber and can compact and flatten the copper flat wire 0 while stably driving the copper flat wire 0 to move forward.

[0042] The driving mechanism includes: a transmission shaft 71 connected to the output shaft of the motor 3 through a coupling and rotatably connected to the inner wall of the shell 2; a limit block 72 connected to the bottom of the shell 2 through bolts; a rotating shaft 73 rotatably connected to the limit block 72; two bevel gears 74 connected to one end of the transmission shaft 71 and the rotating shaft 73 close to each other through a keyway and meshing with each other; a transmission gear 75 connected to the same side of the two positive pressure rollers 63 through a keyway and meshing with each other; a fixed shaft 76 welded to one side of one of the positive pressure rollers 63; a transmission assembly 77 arranged between the fixed shaft 76 and the rotating shaft 73, and the rotating shaft 73 drives one of the positive pressure rollers 63 to rotate through the transmission assembly 77 and the fixed shaft 76.

[0043] The transmission assembly 77 consists of two continuously variable wheels arranged in opposite directions and a leather rope. The two continuously variable wheels of the transmission assembly 77 are respectively connected to the fixed shaft 76 and the rotating shaft 73 through flat keys. The leather rope of the transmission assembly 77 is wrapped around the two continuously variable wheels. The side with the smallest diameter of the continuously variable wheel is the deceleration end, and the side with the largest diameter is the acceleration end. The two sides of the leather rope are respectively located at the deceleration end and the acceleration end of the two continuously variable wheels.

[0044] First, the staff unscrews the locking block 46 from the tube shaft 45 through the thread, and at the same time, puts the two coating disks 47 with insulating paper 48 wound on the two tube shafts 45 respectively. Then the staff twists the locking block 46 back onto the tube shaft 45 to limit the coating disk 47. Then the staff connects the insulating glue to the top of the glue delivery rack 51 through the external pump and the external pipeline, and starts the external pump at the same time. The external pump soaks the insulating glue into the sponge through the glue delivery rack 51 and slowly discharges it. When the copper flat wire 0 needs to be coated with glue, the staff inserts one end of the copper flat wire 0 to be coated into the shell 2 from the feed port of the shell 2 and passes through the glue delivery rack 51 and the rotating disk 41. At the same time, the surface of the copper flat wire 0 will contact the sponge soaked with insulating glue, and the sponge will continue to apply insulating glue to the surface of the copper flat wire 0 to facilitate the subsequent coating of insulating paper 48. The copper flat wire 0 continues to move and contacts the side pressure roller 62 and the positive pressure roller 63. At this time, the staff puts one end of the two insulating papers 48 as shown in FIG. Figure 4As shown, it is pulled out from the coating disk 47 and adhered to the surface of the copper flat wire 0 through insulating glue; when the copper flat wire 0 needs to be coated, the staff starts the motor 3, and the output shaft of the motor 3 rotates to drive the transmission shaft 71 and the driving gear 43 to rotate together, and the transmission shaft 71 drives the rotating shaft 73 to rotate through two mutually meshing bevel gears 74, and the rotating shaft 73 rotates through the transmission component 77 to drive one of the positive pressure rollers 63 to rotate, and one of the positive pressure rollers 63 rotates through two mutually meshing transmission gears 75 to drive the other positive pressure roller 63 to rotate in the opposite direction. In this way, the rotation of the rotating shaft 73 will cause the two positive pressure rollers 63 to rotate in the opposite direction through the transmission component 77 and the two transmission gears 75, thereby driving the copper flat wire 0 to move toward the direction close to the discharge port of the shell 2, and at the same time, the driving gear 43 drives the rotating disk 41 to rotate through the ring gear 42, and the rotation of the rotating disk 41 drives The fixing rod 44, the tube shaft 45, the locking block 46 and the coating disk 47 rotate together, and the rotation of the coating disk 47 drives the two insulating papers 48 to be wound around the surface of the copper flat wire 0, and bonded to the copper flat wire 0 through the insulating glue. In this way, the insulating paper 48 can be wound around the surface of the copper flat wire 0 coated with the insulating glue while driving the copper flat wire 0 to move, which significantly improves the coating efficiency. The tube shaft 45 inclined to the copper flat wire 0 will make the pulled insulating paper 48 obliquely wound around the surface of the copper flat wire 0, thereby reducing the risk of the moving copper wire tearing the insulating paper 48, and the positive pressure roller 63 and the side pressure roller 62 will respectively compact and flatten the four sides and four corners of the copper flat wire 0, thereby improving the coating quality and enhancing the coating effect. After the coating is completed, the copper flat wire 0 passes through the outer shell 2, and the staff turns off the external pump and motor 3, and takes out the coated copper flat wire 0 at the same time.

[0045] Example 2: Based on Example 1, Figures 1-4 and Figure 10-14 As shown, an adjustment mechanism is also included for changing the travel speed of the copper flat wire 0 by adjusting the transmission assembly 77 according to the width of the insulating paper 48, and is provided on the shell 2, and the adjustment mechanism includes: a slide rail frame 81 welded on the inner wall of the shell 2; an adjustment screw 82 rotatably connected to the shell 2, and the adjustment end of the adjustment screw 82 is located outside the shell 2; a threaded block 83 connected to the adjustment screw 82 by a thread; an adjustment frame 84 connected to the threaded block 83 by a bolt and slidingly connected to the slide rail frame 81, the leather rope of the transmission assembly 77 passes through the inside of the adjustment frame 84, and the adjustment frame 84 is used to adjust the leather rope position of the transmission assembly 77; a plurality of balls 85 embedded in the adjustment frame 84, each ball 85 is in contact with the leather rope surface of the transmission assembly 77, and the ball 85 is used to separate the direct contact between the adjustment frame 84 and the leather rope to prevent the leather rope from slipping on the continuously variable transmission wheel due to excessive friction from other forces.

[0046] Initially, the leather rope position of the transmission assembly 77 causes the rotating shaft 73 to drive the fixed shaft 76 to rotate faster through the transmission assembly 77. When a narrower insulating paper 48 is needed to wrap the copper flat wire 0, the staff can rotate the adjusting screw 82 a certain number of times according to the degree of narrowing of the insulating paper 48, and then drive the adjusting frame 84 and the ball 85 to move a certain distance toward the adjustment end of the adjusting screw 82 through the threaded block 83. The movement of the adjusting frame 84 and the ball 85 drives the leather rope of the transmission assembly 77 to move a certain distance. During the movement, the upper contact diameter of the leather rope of the transmission assembly 77 becomes larger and the lower contact diameter becomes smaller, so that the speed at which the rotating shaft 73 drives the fixed shaft 76 to rotate through the transmission assembly 77 slows down, and then the travel speed of the copper flat wire 0 is slowed down, thereby avoiding the copper flat wire 0 from being wound on the copper flat wire 0 due to the mismatch between the travel speed and the width of the insulating paper 48, resulting in gaps or accumulation of the insulating paper 48. It can adapt to insulating paper 48 of different widths, improve the applicability of the device, and further enhance the wrapping effect.

[0047] Example 3: Based on Example 2, Figure 6 and Figure 5-Figure 17 As shown, both sides of the two tube shafts 45 are provided with strip grooves 451, and the strip grooves 451 are connected to the interior of the tube shaft 45. A tensioning mechanism is also included for changing the tensioning force of the insulating paper 48 by adjusting the rotational resistance of the coating disk 47 according to the toughness strength of the insulating paper 48 to prevent the insulating paper 48 from breaking. The tensioning mechanism is provided on the tube shaft 45. The tensioning mechanism includes: an adjusting shaft 91 rotatably connected to the two tube shafts 45; two clamping shafts 92 connected to the two adjusting shafts 91 respectively through keyways, and two clamping shafts 92 on the two clamping shafts There are six card slots 921 on each of them; friction strips 93 are respectively slidably connected to the four strip grooves 451, and the four friction strips 93 are in contact with the two covering disks 47 respectively, and the friction strips 93 are used to adjust the rotational resistance of the covering disk 47; pressure frames 94 are respectively slidably connected to the four friction strips 93, and the side of the pressure frame 94 close to the adjustment shaft 91 is located in one of the card slots 921, and two compression springs 95 are connected between the pressure frame 94 and the friction strips 93, a total of eight, and the card shaft 92 is used to squeeze the pressure frame 94.

[0048] The three slots 921 on the same side of the card shaft 92 are grouped into four groups. The distances between the three slots 921 in each group and the axis of the card shaft 92 increase successively. The three slots 921 in the same group are used to clamp the same pressure frame 94 at positions with different distances from the axis of the card shaft 92.

[0049] When the width of the insulating paper 48 is large, the staff can rotate the adjusting shaft 91 before starting the motor 3. The adjusting shaft 91 drives the card shaft 92 to rotate, and the card shaft 92 rotates to squeeze the pressure frame 94, so that the pressure frame 94 moves away from the card shaft 92 and is stuck in the card groove 921 far away from the axis of the card shaft 92. Under the action of the compression spring 95, the friction strip 93 applies pressure to the inner side of the coating disk 47, so that the rotation resistance of the coating disk 47 is increased, thereby allowing the wider insulating paper 48 to be more fully coated on the surface of the copper flat wire 0. When the width of the insulating paper 48 is small, the staff rotates in the opposite direction. The dynamic adjustment shaft 91 allows the pressure frame 94 to be clamped into the clamping groove 921 closer to the axis of the clamping shaft 92, thereby reducing the rotational resistance of the wrapping disk 47 and avoiding the risk of the insulating paper 48 with a smaller width being torn off due to the large pulling force. In this way, the staff can adjust the rotational resistance of the wrapping disk 47 according to the width of the insulating paper 48, thereby increasing the wrapping strength of the insulating paper 48 while avoiding the risk of the insulating paper 48 being torn off due to the mismatch between the width of the insulating paper 48 and the rotational resistance of the wrapping disk 47, further improving the applicability of the device and further enhancing the wrapping effect.

Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
