Cable surface color strip coating device

Abstract

The invention relates to the technical field of cable processing, in particular to a cable surface color strip coating device which comprises a rack, a guide assembly, a first coating mechanism and a second coating mechanism. And after the cable sequentially passes through the guide assembly, the first coating mechanism and the second coating mechanism, the advancing path of the cable is changed by the reversing wheel. When the cable passes through the guide assembly, the guide assembly not only can limit the advancing direction of the cable, adjust the tension degree of the cable and stably convey the cable to the first coating mechanism, but also can increase the roughness of the outer surface of a coating layer of the cable. By increasing the roughness of the outer surface of the coating layer, coloring of the outer surface of the coating layer is facilitated. When the cable passes through the first coating mechanism, the first coating mechanism can pre-coat the outer surface of the coating layer. And when the cable passes through the second coating mechanism, the second coating mechanism can re-coat the outer surface of the coating layer. Through primary coating and secondary coating, the coating effect of the color bar can be effectively improved.

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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.

[0019] As described in the background art, when a color stripe is coated on the outer surface of the cable coating layer by means of a conventional cable surface color stripe coating device, the coating effect is poor.

[0020] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The present invention provides a cable surface color strip coating device, comprising a frame 110, a guide assembly 120, a first coating mechanism 130, a second coating mechanism 140 and a reversing wheel 150. The guide assembly 120 is installed at the lower part of the frame 110. The first coating mechanism 130 is installed at the upper part of the frame 110. The second coating mechanism 140 is installed at the top of the frame 110. The reversing wheel 150 is rotatably arranged above the frame 110 around its own axis. The guide assembly 120 is used to guide the cable 200 to move upward. After the cable 200 passes through the guide assembly 120, the first coating mechanism 130 and the second coating mechanism 140 in sequence, the reversing wheel 150 changes the travel path of the cable 200. When the cable 200 passes through the guide assembly 120, the guide assembly 120 can not only limit the travel direction of the cable 200, adjust the tension of the cable 200, and stably transport the cable 200 to the first coating mechanism 130, but also increase the roughness of the outer surface of the coating layer of the cable 200. By increasing the roughness of the outer surface of the coating layer, it is beneficial to color the outer surface of the coating layer. When the cable 200 passes through the first coating mechanism 130, the first coating mechanism 130 can pre-coat the outer surface of the coating layer. When the cable 200 passes through the second coating mechanism 140, the second coating mechanism 140 can re-coat the outer surface of the coating layer. Through primary coating and secondary coating, the color strip coating effect can be effectively improved.

[0021] Specifically, in the example, Figure 1 As shown, the frame 110 includes a bottom ring 111 of a circular ring structure, a first support ring 112 of a circular ring structure, and a second support ring 113 of a circular ring structure. First connecting ears 1111 are respectively arranged on opposite sides of the bottom ring 111. A threaded hole is provided on the first connecting ear 1111 on each side, and the bottom ring 111 can be fixed to the base using bolts. The first support ring 112 is arranged above the bottom ring 111 and is fixedly connected to the bottom ring 111 through a support rod 114. A first coating mechanism 130 is installed on the first support ring 112. The second support ring 113 is arranged above the first support ring 112 and is fixedly connected to the first support ring 112 through a support rod 114. A second coating mechanism 140 is installed on the second support ring 113.

[0022] Preferably, the inner diameter of the bottom ring 111 is 25-35 cm, the wall thickness is 3-6 mm, and the height is 5-10 cm. The inner diameter of the first support ring 112 is 15-20 cm, the wall thickness is 3-6 mm, and the height is 1-2 cm. The inner diameter of the second support ring 113 is 10-15 cm, the wall thickness is 3-6 mm, and the height is 1-2 cm.

[0023] Specifically, in the example, Figure 1 and Figure 2As shown, the guide assembly 120 includes a bracket 121, a lower guide wheel 122, an upper guide wheel 123 and two rolling wheels 124. The bracket 121 is mounted on the lower part of the frame 110. The lower guide wheel 122 is rotatably mounted on the lower part of the bracket 121 around its own axis. The upper guide wheel 123 is rotatably mounted on the upper part of the bracket 121 around its own axis. A guide groove is formed in the middle of the side wall of the upper guide wheel 123 and the lower guide wheel 122. On the one hand, the guide groove better constrains the cable 200 to move upward; on the other hand, the guide groove limits the axial movement of the cable 200 along the upper guide wheel 123 or the lower guide wheel 122. The two rolling wheels 124 are respectively rotatably mounted on the middle part of the bracket 121 around their own axes. The two rolling wheels 124 are arranged side by side, and a cable 200 channel is formed between them. The outer side surface of each rolling wheel 124 is a sand surface. The sanding surface can act on the outer surface of the coating layer of the cable 200 to increase the roughness of the outer surface of the coating layer of the cable 200 .

[0024] Preferably, the bracket 121 is in a "T" shape as a whole, including a horizontal beam and a vertical beam. One end of the horizontal beam is fixedly connected to the support rod 114 at the bottom of the frame 110, and the other end is fixedly connected to the middle of the vertical beam. The lower guide wheel 122 is rotatably mounted on the bottom end of the vertical beam. The upper guide wheel 123 is rotatably mounted on the top of the vertical beam. One of the rolling wheels 124 is rotatably mounted on the middle of the vertical beam, and the other rolling wheel 124 is rotatably mounted on one end of the horizontal beam close to the vertical beam.

[0025] Specifically, in the example, Figure 1 , Figure 3 and Figure 4The first coating mechanism 130 includes more than two first coating pen barrels 131, more than two first coating pen tips 132, more than two first dye storage tanks 133 and more than two first peristaltic pumps 134. The more than two first coating pen barrels 131 are evenly distributed along the circumference of the frame 110. The axis of each first coating pen barrel 131 is tilted and can be installed on the first support ring 112 at the upper part of the frame 110 movably along its own axial direction. The top of each first coating pen barrel 131 is formed with a first dye inlet, the inside is formed with a first dye flow cavity, and the bottom is formed with a first dye outlet. The more than two first coating pen tips 132 are installed at the bottom end of the first coating pen barrel 131 in a one-to-one correspondence with the first coating pen barrel 131, and can move along the axial direction of the corresponding first coating pen barrel 131 with the corresponding first coating pen barrel 131. Each first coating pen tip 132 includes a first fixing plate 1321 and a first flexible coating portion 1322. The positive projection of the first fixing plate 1321 from top to bottom is an arc structure. The convex surface of the first fixed plate 1321 is fixedly connected to the bottom end of the first coating pen barrel 131. The positive projection of the first flexible coating part 1322 from top to bottom is an arc structure, and the arc length can be adjusted according to the width of the color strip. The convex surface of the first flexible coating part 1322 is fixedly connected to the concave surface of the first fixed plate 1321, and a first cable path groove 13221 is formed on the concave surface. A first dye outlet is also provided on the first fixed plate 1321 so that the first flexible coating part 1322 can contact the dye in the first dye flow cavity. Two or more first dye storage tanks 133 are connected to the first dye inlets on the two or more first coating pen barrels 131 in a one-to-one correspondence through a hose. A first peristaltic pump 134 is arranged on the pipeline connecting each first dye storage tank 133 and a first dye inlet. Each first dye storage tank 133 is used to store a dye of one color. The two or more first dye storage tanks 133 can store dyes of the same color or dyes of different colors, which can be selected according to the color of the color strip. Each first peristaltic pump 134 can provide power for the flow of dye and accurately control the flow rate of the colorant. If the flow rate is too slow, the coated color stripes will be discontinuous. If the flow rate is too fast, the colorant will escape too much, which may easily lead to uneven color strip width. The first flexible coating portion 1322 is a porous flexible material with good water absorption. The dye from the first dye storage tank 133 flows through the first peristaltic pump 134, the first dye inlet, the first dye flow cavity and the first dye outlet in sequence, and then reaches the first flexible coating portion 1322. When the cable 200 passes through the first cable path groove 13221, the first flexible coating portion 1322 can apply color strips to the cable 200.Moreover, before applying the color stripes, each first coating pen barrel 131 can move along its own axial direction to adjust the force between the first flexible coating portion 1322 of the corresponding first coating pen head 132 and the cable 200, ensuring that the first flexible coating portion 1322 is in close contact with the outer surface of the sheathing layer of the cable 200 to ensure the coating effect.

[0026] Specifically, in the example, Figure 1 and Figure 5As shown, the second coating mechanism 140 includes more than two second coating pen barrels 141, more than two second coating pen heads 142, more than two second dye storage tanks 143 and more than two second peristaltic pumps 144. More than two second coating pen barrels 141 are evenly distributed along the circumference of the frame 110. The axis of each second coating pen barrel 141 is tilted and can be installed on the second support ring 113 at the top of the frame 110 movably along its own axial direction. The top of each second coating pen barrel 141 is formed with a second dye inlet, a second dye flow cavity is formed inside, and a second dye outlet is formed at the bottom. More than two second coating pen heads 142 are installed at the bottom of the second coating pen barrel 141 in a one-to-one correspondence with the second coating pen barrel 141, and can move along the axial direction of the corresponding second coating pen barrel 141 with the corresponding second coating pen barrel 141. Each second coating pen head 142 includes a second fixing plate 1421 and a second flexible coating portion 1422. The positive projection of the second fixing plate 1421 from top to bottom is an arc structure. The convex surface of the second fixed plate 1421 is fixedly connected to the bottom end of the second coating pen barrel 141. The positive projection of the second flexible coating part 1422 from top to bottom is an arc structure, and the arc length can be adjusted according to the width of the color strip. The convex surface of the second flexible coating part 1422 is fixedly connected to the concave surface of the second fixed plate 1421, and a second cable path groove is formed on the concave surface. A second dye outlet is also provided on the second fixed plate 1421 so that the second flexible coating part 1422 can contact the dye in the second dye flow cavity. More than two second dye storage tanks 143 are connected to the second dye inlet on more than two second coating pen barrels 141 in a one-to-one correspondence through a hose. A second peristaltic pump 144 is provided on the pipeline connecting each second dye storage tank 143 and a second dye inlet. Each second dye storage tank 143 is used to store a dye of one color. More than two second dye storage tanks 143 can store dyes of the same color or dyes of different colors, depending on the color of the color strip. Each second peristaltic pump 144 can provide power for the flow of dyes and accurately control the flow rate of colorants. If the flow rate is too slow, the color stripes of the coating will be discontinuous. If the flow rate is too fast, the colorants will escape too much, which will easily lead to uneven width of the color stripes. The second flexible coating part 1422 is a porous flexible material with good water absorption. The dye from the second dye storage tank 143 flows through the second peristaltic pump 144, the second dye inlet, the second dye flow through the cavity and the second dye outlet in sequence, and then reaches the second flexible coating part 1422. When the cable 200 passes through the second cable path groove, the second flexible coating part 1422 can apply color stripes to the cable 200. Moreover, before the color stripes are applied, each second coating pen barrel 141 can move along its own axial direction to adjust the force between the second flexible coating part 1422 of the corresponding second coating pen head 142 and the cable 200, and ensure that the second flexible coating part 1422 is in close contact with the outer surface of the coating layer of the cable 200 to ensure the coating effect.

[0027] Preferably, the first coating pen barrel 131 can be two, three, four, five or more than six, and correspondingly, the first coating pen head 132, the first dye storage tank 133 and the first peristaltic pump 134 are all two, three, four, five or more than six. Correspondingly, the second coating pen barrel 141, the second coating pen head 142, the second dye storage tank 143 and the second peristaltic pump 144 are all two, three, four, five or more than six. In this way, two, three, four, five or more than six color strips can be coated on the outer surface of the coating layer of the cable 200 along the axial direction of the cable 200.

[0028] Preferably, the material of the first flexible coating portion 1322 is woven fabric, and the material of the second flexible coating portion 1422 is sponge. The water absorption of the second flexible coating portion 1422 is better than that of the first flexible coating portion 1322. When the second flexible coating portion 1422 releases too much dye, the excess dye flows downward along the outer surface of the coating layer of the cable 200, and the first flexible coating portion 1322 can prevent the dye from continuing to flow downward along the outer surface of the coating layer of the cable 200.

[0029] Preferably, the included angle between the axis of each first coating pen barrel 131 and the horizontal plane is 45°. The included angle between the axis of each second coating pen barrel 141 and the horizontal plane is 45°.

[0030] It should be noted that the color of the dye stored in each first dye storage tank 133 is at least the same as the color of the dye stored in one of the second dye storage tanks 143 .

[0031] Specifically, in the example, Figure 1 , Figure 6 and Figure 7As shown, the first support ring 112 is provided with two, three, four, five or more than six mounting holes along the circumference. The frame 110 also includes a first adjustment seat 115 and a second adjustment seat 116. There are two, three, four, five or more than six first adjustment seats 115, which are evenly distributed along the circumference of the first support ring 112. Each first adjustment seat 115 includes an adjustment plate 1151, a cross bar 1152, a locking bolt 1153, a locking nut 1154 and a locking screw 1155. The bottom of the adjustment plate 1151 is bent to form a second connecting ear 11511. The second connecting ear 11511 can be fixed to the first support ring 112 through the mounting hole using the locking screw 1155, so that each first adjustment seat 115 is fixedly installed on the first support ring 112. Two oblong adjustment holes 11512 are provided on the adjustment plate 1151. One end of the cross bar 1152 can be fixedly connected to the adjustment plate 1151 through one of the locking bolts 1153 and one of the locking nuts 1154, and the other end of the cross bar 1152 can be fixedly connected to the adjustment plate 1151 through another locking bolt 1153 and another locking nut 1154. A constraint ring 11521 is formed in the middle of the cross bar 1152, and the constraint ring 11521 is adapted to the first coating pen barrel 131 and can limit the position of the first coating pen barrel 131. By adjusting the position of the cross bar 1152, the position of the first coating pen barrel 131 is further adjusted, so that the first coating pen barrel 131 of the first coating mechanism 130 can move along its own axial direction. Similarly, the second support ring 113 is also provided with two, three, four, five or more than six mounting holes along the circumferential direction. The second adjustment seat 116 is two, three, four, five or more than six, and is evenly distributed along the circumference of the second support ring 113. The specific structure of each second adjustment seat 116 is the same as that of each first adjustment seat 115. Each second adjustment seat 116 can be fixedly mounted on the second support ring 113 using a locking screw 1155. By adjusting the position of the crossbar 1152 of the second adjustment seat 116, the position of the second coating pen barrel 141 is adjusted, so that the second coating pen barrel 141 of the second coating mechanism 140 can move along its own axial direction.
