Description

Technical Field

[0001] The invention relates to the technical field of film-coated wire processing, and in particular to a film coating device for film-coated wire processing. Background Art

[0002] Film-coated wire, also known as coated cable, is a cable product characterized by a thin film covering the outer layer of the cable. This film is usually made of polyester (PET), polyvinyl chloride (PVC) or other polymer materials, and has good insulation, corrosion resistance, mechanical strength and wear resistance.

[0003] During the processing of film-wrapped wire, the coating glue is mainly sprayed on the surface of the cable, and then the cable is sent into the coating machine to cover the surface with polyester film, and then it is extruded under pressure. During the process of pressurized extrusion, a certain pressure is applied to the polyester film, which helps to remove the air between the film and the coating glue and promote close contact between the two. However, the existing coating devices for film-wrapped wire processing have the following problems in actual operation:

[0004] First, the traditional technology generally uses a spraying technique to spray the coating adhesive on the surface of the cable. This method cannot evenly apply the coating adhesive on the surface of the cable, and thus cannot guarantee the bonding effect between the film and the cable in the subsequent coating process, which reduces the coating effect.

[0005] Secondly, after the lamination is completed, it is generally necessary to guide the cable out of the laminating machine through a guide wheel. However, the cable cannot be fully and evenly cooled during the guiding process, which is not conducive to fully cooling and curing the coating layer, thereby reducing the forming efficiency and quality of the film-wrapped wire. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a coating device for film-wrapped wire processing, which effectively solves the problem that the existing coating devices for film-wrapped wire processing generally spray the coating glue on the surface of the cable by means of a spraying technology, but this method cannot evenly apply the coating glue on the surface of the cable, and thus cannot ensure the bonding effect between the film and the cable in the subsequent coating process, thereby reducing the coating effect. The problem also solves the problem that after the coating is completed, the cable generally needs to be guided out of the coating machine by a guide wheel, but the cable cannot be fully and evenly cooled during the guiding process, which is not conducive to fully cooling and curing the coating layer, thereby reducing the forming efficiency and quality of the film-wrapped wire.

[0015] As a preferred technical solution of the present invention, the cooling mechanism includes a cooling air pump fixedly mounted on the top outer wall of the base, a branch main pipe fixedly connected to the air outlet of the cooling air pump, and guide components alternately distributed at equal distances.

[0016] As a preferred technical solution of the present invention, the guide assembly includes a fixing frame fixedly connected to the side wall of the laminating machine and a hollow guide roller rotatably mounted on the fixing frame, and the surface of the hollow guide roller is provided with evenly distributed air holes.

[0017] As a preferred technical solution of the present invention, the main branch pipe is fixedly connected with branch pipes having the same number as the guide components, and each branch pipe is connected to each hollow guide roller through a rotary joint.

[0018] As an optimal technical solution of the present invention, the wire-taking mechanism includes two supporting frames fixedly connected to the outer wall of the top of the base in sequence, a wire-taking roller rotatably installed between the two supporting frames, a motor support seat welded to the outer wall of the rear side of one of the supporting frames, a speed-changing motor fixedly installed on the outer wall of the rear side of the motor support seat, a speed-changing gear fixedly mounted on the output shaft of the speed-changing motor, and a transmission gear fixedly mounted on the wire-taking roller.

At this time, the cooling air pump sends the cold air to the branch main pipe and flows into each hollow guide roller through each branch pipe. Finally, the cold air is discharged from the air holes evenly distributed on the surface of the hollow guide roller to fully and evenly cool the cable wire in the guiding process, thereby helping to fully cool and solidify the coating layer and improve the forming efficiency and quality of the film-wrapped wire.

[0026] 6. When the wire is taken up, the present invention can flexibly adjust the wire taking-up speed according to different usage conditions through the speed-changing coordination of the speed-changing motor and the speed-changing gear, thereby improving the flexibility of use.

[0043] Further, one end of the driving shaft 10 is coaxially fixedly connected to the output shaft of the driving motor 9, and the glue coating wheel 11 and the glue dipping wheel 14 are in contact with each other and form a rolling fit;

[0045] Further, the guide component includes a guide rail 18 fixedly connected to the top outer wall of the laminating machine 2 and a guide block 19 fixedly connected to the bottom outer wall of the glue storage box 7 and slidably connected to the guide rail 18, and one end outer wall of the two connecting rods 23 is respectively fixed to the front outer wall of the two guide blocks 19;

[0046] In the specific implementation of this embodiment: first, the cable wire paid out by the pay-off roller 4 will be cleaned by the cleaning sleeve 6, which can effectively reduce the floating dust on the surface of the cable wire and improve the subsequent coating quality of the cable wire;

[0049] Example 2, reference Figure 1 and Figure 6-8 , This embodiment is optimized on the basis of embodiment 1, specifically: a film coating device for film-coated wire processing, further comprising a cooling mechanism;

[0050] In this embodiment, the cooling mechanism includes a cooling air pump 24 fixedly mounted on the top outer wall of the base 1, a flow distribution main pipe 25 fixedly connected to the air outlet end of the cooling air pump 24, and guide components alternately distributed at equal distances;

[0052] Furthermore, the main flow distribution pipe 25 is fixedly connected with the same number of branch flow distribution pipes as the guide components, and each branch flow distribution pipe is connected to each hollow guide roller 27 through a rotary joint 28;

[0053] During the specific implementation of this embodiment: the cable line after coating is guided out of the coating machine 2 by the hollow guide rollers 27 distributed at equal distances. At this time, the cold air is sent to the branch main pipe 25 through the cooling air pump 24 and flows into each hollow guide roller 27 through each branch pipe. Finally, the cold air will be discharged from the air holes evenly distributed on the surface of the hollow guide roller 27 to fully and evenly cool the cable line in the guiding process, thereby helping to fully cool and solidify the coating layer and improve the molding efficiency and quality of the film-wrapped wire.

[0054] Example 3, reference Figure 1 and Fig. 9 This embodiment is optimized on the basis of the embodiment 1, specifically: a film coating device for film-wrapped wire processing, further comprising a wire taking-up mechanism, the wire taking-up mechanism comprising:

[0055] Two bearing frames 29 and a take-up roller 30. The two bearing frames 29 are fixedly connected to the top outer wall of the base 1 in sequence, and the take-up roller 30 is rotatably installed between the two bearing frames 29;

[0056] A motor support seat 31 and a variable speed motor 32. The motor support seat 31 is welded to the rear outer wall of one of the carrier frames 29. The variable speed motor 32 is fixedly mounted on the rear outer wall of the motor support seat 31. The output shaft of the variable speed motor 32 passes through the motor support seat 31.

[0057] A speed change gear 33 and a transmission gear 34, wherein the speed change gear 33 is fixedly mounted on the output shaft of the speed change motor 32, and the transmission gear 34 is fixedly mounted on the take-up roller 30, and the speed change gear 33 and the transmission gear 34 are meshed with each other;

[0058] In the specific implementation of this embodiment: the speed change gear 33 is controlled to rotate by the speed change motor 32, and then the transmission gear 34 meshing with the speed change gear 33 controls the rotation of the take-up roller 30 to uniformly collect and organize the guided and cooled film-wrapped wires, and through the speed change coordination of the speed change motor 32 and the speed change gear 33, the take-up speed can be flexibly adjusted according to different usage conditions, thereby improving the flexibility of use.

[0059] The use process of the present invention is as follows: in the first step, the cable wire paid out by the pay-off roller 4 is cleaned by the cleaning sleeve 6, which can effectively reduce the floating dust on the surface of the cable wire and improve the subsequent coating quality of the cable wire;

[0060] In the second step, the bidirectional screw 21 is driven to rotate by the hand wheel 22. Under the guidance of the two guide components, the two connecting rods 23 threadedly connected to the bidirectional screw 21 drive the two glue coating components fixed on the top of the two guide blocks 19 to align and move closer, so that the working distance between the two glue coating wheels 11 can be flexibly adjusted, thereby better adapting to the glue coating processing of cables of different thicknesses;

[0061] The third step is that when the glue coating assembly is in use, the driving motor 9 controls the glue coating wheel 11 and the first pulley 15 on the driving shaft 10 to rotate, and then under the transmission effect of the transmission belt 17, the second pulley 16 will drive the stirring blade 13 and the glue dipping wheel 14 on the transmission shaft 12 to rotate. In this way, through the rolling cooperation formed between the glue dipping wheel 14 and the glue coating wheel 11, the rotating glue dipping wheel 14 can continuously and evenly dip glue onto the glue coating wheel 11, and then through the two rotating glue coating wheels 11 constantly contacting the cable wire located therebetween, the glue can be evenly applied to the surface of the cable wire, thereby improving the bonding effect between the film and the cable wire in the subsequent coating process, improving the coating effect, and in the process of coating, the two stirring blades 13 will also rotate, which can fully stir the glue in the two glue storage boxes 7 to prevent the glue from being left to solidify;

[0062] The fourth step is to guide the coated cable out of the laminating machine 2 through the hollow guide rollers 27 distributed at equal distances. At this time, the cooling air pump 24 sends the cold air to the branch pipe 25 and flows into each hollow guide roller 27 through each branch pipe. Finally, the cold air will be discharged from the air holes evenly distributed on the surface of the hollow guide roller 27 to fully and evenly cool the cable in the guiding process, thereby helping to fully cool and solidify the coating layer and improve the forming efficiency and quality of the film-wrapped wire.

[0063] The fifth step is to control the speed gear 33 to rotate through the speed motor 32, and then the transmission gear 34 meshing with the speed gear 33 will control the take-up roller 30 to rotate to uniformly collect and organize the guided and cooled film-wrapped wires. Through the speed coordination of the speed motor 32 and the speed gear 33, the take-up speed can be flexibly adjusted according to different usage conditions, thereby improving the flexibility of use.
