Description

Technical Field

[0001] The invention relates to the technical field of enameled wire painting equipment, in particular to a high-precision paint leakage-proof painting mould. Background Art

[0002] The enameled wire is composed of an inner bare wire and the paint that wraps the bare wire. The quality of the enameled wire is mainly reflected in whether the paint film on the surface of the bare wire is uniform and smooth. The painting process of the bare wire needs to be carried out by a painting device. The painting mold in the painting device has an important impact on the quality of the enameled wire. Most of the painting equipment in the prior art adheres the paint to the surface of the wire core by infiltration. When the wire core moves, due to the viscosity and surface tension of the paint, the surface paint will move with the wire core, thereby dripping on the outside of the painting mold, or hanging on the outside of the wire core to form a local bulge; at the same time, the paint on the upper side of the wire core is easy to flow downward when it is not dry, making the paint thickness on the outside of the wire core uneven.

DETAILED DESCRIPTION

[0033] 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.

[0034] Example 1

[0035] A high-precision paint-leakage-proof painting mold, such as Figure 1-Figure 7 As shown, it includes a support frame 1; a traction mechanism 2 is connected to the support frame 1 for clamping the enameled wire.

[0036] Specifically, a card slot 11 is opened on one side of the support frame 1, and a card block 12 is connected to the other side of the support frame 1. The card block 12 corresponds to the card slot 11. The card slot 11 structure can cooperate with the card block 12 to connect two or more support frames 1 to each other, thereby realizing simultaneous painting processing operations on different numbers of wire cores.

[0037] On this basis, the traction mechanism 2 includes a clamping frame 21, which is slidably connected to the side of the support frame 1. The structure of the clamping frame 21 can support the traction mechanism 2, and the sliding clamping frame 21 can pull and tug the wire core. A clamping hole 22 is provided in the middle of the clamping frame 21, and the clamping hole 22 can facilitate the positioning of the wire core. A clamping rod 23 is connected inside the clamping frame 21, and a clamping block 24 is fixedly connected to the clamping rod 23. The positions of the clamping block 24 and the clamping hole 22 correspond to each other. The clamping block 24 is a cylindrical structure, and the middle of the clamping block 24 is concave inward, so that the wire core or the enameled wire can be clamped. At the same time, the clamping rod 23 can rotate inside the clamping frame 21, so as to pull the wire core or the painted enameled wire.

[0038] It is worth noting that the clamping block 24 is rotatably connected to a clamping spring 25 on the outside, and the end of the clamping spring 25 is connected to a traction frame. The traction frame is a U-shaped structure, and the end of the traction frame is annular and sleeved on both ends of the clamping block 24. The clamping rod 23 can be rotated on the traction frame, so that the clamping rod 23 is driven to clamp the wire core and conveniently rotates and pulls the wire core. The end of the clamping spring 25 is rotatably connected to a connecting rod 26, and the end of the connecting rod 26 is set through the clamping frame 21. The connecting rod 26 structure can drive the clamping rod 23 through the traction frame, so that the clamping rod 23 moves toward each other and clamps the wire core. At the same time, the clamping spring 25 structure can buffer the driving force to prevent the clamping block 24 from squeezing the wire core or enameled wire due to excessive clamping force. The end of the connecting rod 26 is connected to a pulling block 27, and the pulling block 27 structure can drive the connecting rod 26. The support frame 1 is slidably connected to a limit block 28 on the side, and the limit block 28 can limit and drive the pull block 27, so that the clamping rod 23 moves to clamp the wire core while maintaining the clamping state of the clamping rod 23. The limit block 28 is a trapezoidal structure, and the side of the limit block 28 close to the pull block 27 is inclined, so that the pull block 27 can be driven to move by the movement of the limit block 28.

[0039] Furthermore, the traction mechanism 2 also includes a limiting assembly 29, which can limit the movement of the clamping rod 23. The limiting assembly 29 includes a positioning plate 291 slidably connected to the outside of the support frame 1, and a positioning groove 292 is provided on the inner side of the positioning plate 291. The positioning plate 291 can guide the clamping rod 23 through the positioning groove 292, so that when the clamping rod 23 moves toward each other to clamp the wire core, the positioning plate 291 moves synchronously to adapt to the position of the clamping rod 23 in the clamping state. The end of the clamping rod 23 is fixedly connected with a positioning rod 293, which is a prismatic structure. The positioning rod 293 is slidably connected inside the positioning groove 292. The prismatic positioning rod 293 can cooperate with the positioning groove 292, so that when the clamping rod 23 slides along the positioning plate 291, the positioning groove 292 limits the clamping rod 23 to prevent the clamping rod 23 from rotating during the movement. A circular groove 294 is connected to the end of the positioning groove 292, and the circular groove 294 can accommodate the positioning rod 293 to facilitate the rotation of the positioning rod 293. When the clamping plate moves to the end of the support frame 1, the positioning rod 293 moves into the groove 294, so that the clamping rod 23 can be rotated, which is convenient for the subsequent positioning operation of the enameled wire.

[0040] Example 2

[0041] like Figure 2-Figure 4 As shown, on the basis of Example 1, a coating mechanism 3 is provided inside the support frame 1 for coating the wire core, and a drying mechanism 4 is provided at one end of the coating mechanism 3 for drying the enameled wire.

[0042] In this embodiment, the coating mechanism 3 includes a coating chamber 31, which is opened on the side of the support frame 1. The coating chamber 31 can provide a coating processing environment for coating, and the interior of the coating chamber 31 is a cylindrical structure. Support rings 32 are rotatably connected at both ends of the inner side of the coating chamber 31, and a coating tube 33 is fixedly connected between the two support rings 32. The support ring 32 can support the coating tube 33 so that the coating tube 33 can rotate inside the coating chamber 31. A coating hole 34 is provided on the side of the coating tube 33, and a brush 35 is fixedly connected to the inside of the coating hole 34. The coating hole 34 can facilitate the installation operation of the brush 35. At the same time, the brush 35 is arranged inside the coating tube 33 through the coating hole 34. The paint inside the coating tube 33 will not drip from the inside of the coating hole 34 due to the blockage of the brush 35. At the same time, the brush 35 can infiltrate the paint onto the entire brush 35 through capillary action, and by brushing multiple times with a small amount of infiltrated paint, the accuracy of painting can be improved, and excessive coating of paint on the surface of the wire core can be avoided to cause paint dripping or form paint nodules.

[0043] On this basis, a liquid reservoir 36 is provided on the outside of the support ring 32, and the coating tube 33 and the liquid reservoir 36 are interconnected. The liquid reservoir 36 structure can temporarily store the paint, and at the same time can guide the paint to the coating tube 33 and the inside of the support ring 32 on the other side, so as to achieve the continuous flow of the paint and prevent the paint from solidifying inside the coating tube 33. A connecting tube 37 is fixedly connected to the support frame 1, one end of the connecting tube 37 is connected to the inside of the liquid reservoir 36, and the other end of the connecting tube 37 is fixedly connected to the side of the support frame 1. The connecting tube 37 can transport the external paint to the inside of the liquid reservoir 36. At the same time, the end diameters of the two connecting tubes 37 are different, and the outer diameter of one connecting tube 37 is the same as the inner diameter of the other connecting tube 37, so as to facilitate the connection of the connecting tubes 37 on the sides of the two support frames 1.

[0044] Furthermore, the drying mechanism 4 includes a drying chamber 41, which is provided on the side of the coating frame, and the drying chamber 41 can perform air-drying operation on the enameled wire after the painting is completed. The drying chamber 41 and the end of the coating chamber 31 are connected to each other, and the interconnected drying chamber 41 and the coating chamber 31 can allow the wire core to be moved to the drying chamber 41 for air-drying after the coating operation is completed. Drying holes 42 are fixedly connected at both ends of the drying chamber 41, and the drying holes 42 can make the drying chamber 41 communicate with the outside world, and use the airflow from the outside world to dry the wire core after the painting. A driving ring 43 is rotatably connected to one end of the drying chamber 41, and the driving ring 43 is fixedly connected to the support ring 32, and the driving ring 43 structure can drive the support ring 32.

[0045] Example 3

[0046] like Figure 1 , Figure 2 , Figure 4As shown, on the basis of embodiment 1, a driving mechanism 5 is provided inside the support frame 1 for driving the drying mechanism 4 .

[0047] In this embodiment, the driving mechanism 5 includes a screw 51, which is rotatably connected to the inside of the support frame 1, and the screw 51 is meshed with the clamping frame 21. The screw 51 can drive the clamping frame 21, so that the clamping frame 21 drives the clamped wire core to pull and tug to the other end. A gear 52 is fixedly connected to the outer end of the screw 51, and a toothed ring 53 meshing with the gear 52 is fixedly connected to the outer side of the drive ring 43. The gear 52 can cooperate with the toothed ring 53, so that the screw 51 can continuously drive the drive ring 43 and the support ring 32 to rotate while driving the clamping frame 21. The top of the screw 51 is set through the support frame 1, and the top of the screw 51 is fixedly connected to a sprocket 54. When the support frame 1 is assembled and used, a meshing chain can be added to the sprocket 54 to drive the adjacent sprockets 54, so that the combined device can simultaneously paint and tug on multiple wire cores.

[0048] On this basis, the end of the screw 51 is fixedly connected to a reciprocating screw 44, and the outer side of the reciprocating screw 44 is meshedly connected to a moving block 45, and the reciprocating screw 44 can drive the moving block 45 to reciprocate. A piston rod 46 is fixedly connected to one side of the moving block 45, and a piston cylinder 47 is sleeved on the outer side of the piston rod 46. The two ends of the piston cylinder 47 are connected to the drying chamber 41 through a pipeline. The piston rod 46 can continuously reciprocate under the drive of the moving block 45, and squeeze the air inside the piston cylinder 47 outward or draw air in from the outside. After the inside of the drying chamber 41 is connected to the inside of the piston cylinder 47 through the pipeline, the flowing airflow can form a periodic airflow, thereby realizing the drying operation of the enameled wire. In actual use, a dehumidification block can be added to the bottom of the piston cylinder 47 to dehumidify the air drawn into the piston cylinder 47.

[0049] When the high-precision paint-leakage-proof painting mold of the present invention is used, the wire core is first passed through the coating chamber 31 and the drying chamber 41 in sequence, and then passes through the clamping frame 21 from the clamping rod 23. Then the limit block 28 is moved toward the clamping frame 21, and the limit block 28 pushes the pull block 27 outward. During the movement, the pull block 27 drives the clamping spring 25 to rotate through the connecting rod 26, and the clamping spring 25 rotates from the inclined state to the vertical direction, and is continuously compressed under the extrusion of the clamping frame 21. The clamping spring 25 then pushes the clamping rod 23 toward the clamping hole 22 through elasticity, so that the wire core is clamped and fixed by the clamping block 24 on the clamping rod 23. Then, paint is injected into the coating chamber 31 through the connecting pipe 37, and the screw rod 51 is driven to rotate by the driving device. When the screw rod 51 rotates, the clamping frame 21 moves toward the end away from the drying chamber 41, and pulls the wire core to move synchronously during the movement. After being injected into the storage tank, the paint flows along the connecting pipe 37, and after flowing through the brush 35, the brush 35 is soaked. While the screw 51 moves, the gear ring 53 is driven to rotate by the outer gear 52, and the support ring 32 is rotated under the transmission of the drive ring 43, and the paint is applied to the surface of the wire core by the brush 35. The enameled wire after painting moves to the inside of the drying chamber 41, and the enameled wire is dried through the pipe on the side of the drying chamber 41. When the clamping frame 21 moves to disengage from the screw 51, the positioning rod 293 moves to the inside of the circular groove 294, and the positioning rod 293 inside the groove 294 can rotate. When the enameled wire is subsequently wound and stored, the clamping block 24 can facilitate the movement of the enameled wire between the clamping blocks 24 while clamping and positioning the enameled wire. While the screw 51 is rotating continuously, the reciprocating screw rod 44 at the end of the screw 51 is rotating continuously and drives the moving block 45 to move back and forth, and the piston rod 46 on the moving block 45 is moving inside the piston cylinder 47, thereby discharging air into the drying chamber 41 through the pipeline or extracting air from the drying chamber 41, forming a dry wind to dry the enameled wire. When multiple devices need to be spliced ​​and assembled, the block 12 on the adjacent support frame 1 is inserted into the card slot 11, and the connecting pipes 37 on the corresponding sides are connected to each other, so that the mutual assembly of the support frames 1 can be completed. After assembly, the sprocket wheels 54 are meshed with each other, and the screws 51 inside the assembled multiple support frames 1 can be driven by the driving device to rotate synchronously. At the same time, after the paint flows out from the connecting pipe 37, it can flow to the inside of the adjacent support frame 1 through the interconnected connecting pipes 37, so as to realize the reuse of the paint.
