Description

Technical Field

[0001] The present invention relates to the technical field of cable sheath processing, and more specifically, to an insulation layer extrusion coating device for cable processing. Background Art

[0002] The cable sheath can play an insulating and protective role. During production, the molten plastic is extruded and coated on the surface of the copper wire through an injection molding extruder. The molten plastic cools and hardens to form the cable sheath.

[0003] In order to improve the cooling effect of the cable sheath, a Chinese patent with publication number "CN109887674A" discloses a cable cooling device, in which new cooling water continuously enters the bellows from the cooling water inlet, and the cooling water with higher temperature near the cooling water outlet is preferentially discharged from the bellows, so that the cooling water temperature in the bellows is maintained at a lower level to ensure the cooling effect;

[0004] However, during the cable winding process, the cable sheath will contact and slide relative to the corrugated tube. At this time, the cable sheath has not yet completely cooled and hardened, resulting in scratches on the cable sheath, greatly reducing product quality. In addition, the cooling water overflows in the curved corrugated tube, resulting in some heated cooling water always remaining in the corrugated tube and unable to be discharged, reducing the cooling effect on the cable. Summary of the invention

[0005] In order to overcome the disadvantage that the cable may come into contact with the corrugated tube during its winding and movement, thereby scratching the cable sheath, the present invention provides an insulation layer extrusion coating device for cable processing.

[0017] Compared with the prior art, the present invention has the following advantages:

During this process, the cable body will not be in contact with the arc plate 1 and the arc plate 2, while retaining the efficient cooling function of the existing device for the cable body, the problem of scratching the outer skin of the cable body is avoided. At the same time, the cooling water in the arc plate 1 and the arc plate 2 flows downward in a pouring manner.

At the same time, the spiral sheet is formed by the combination of arc blocks, and the spiral sheet guides the cooling water downward in a spiral shape, thereby increasing the contact time between the cooling water and the cable body, thereby improving the cooling efficiency of the cable body. At the same time, the cooling water flowing on the arc block is guided to the surface of the cable body by the guide block, which can reduce the temperature of the cooling water around the surface of the cable body, further improving the cooling efficiency of the cable body, so as to ensure the cooling effect;

[0020] 3. The cooling water remaining in the cable body is absorbed by the sponge block. At the same time, the cooling water used to cool the cable body is also used to drive the pressing block to move upward, so that the pressing block can squeeze out the cooling water absorbed in the sponge block, so that the sponge block can regain the water absorption function.

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. Example

[0030] An insulation layer extrusion coating device for cable processing, such as Figure 1-Figure 4 As shown, it includes an injection molding extruder 1, a mold 2, a roller 1 3, a roller 2 4 and a roller 3 5; the output end of the injection molding extruder 1 is connected to and fixedly connected with the mold 2; a roller 1 3 is arranged on the side of the mold 2; a roller 2 4 is arranged on the side of the roller 1 3; a roller 3 5 is arranged above the roller 2 4; it also includes a telescopic cylinder 6, an arc plate 1 7, an arc plate 2 8 and a circulating conveying component; four telescopic cylinders 6 are arranged below the roller 3 5 and above the roller 2 4; two arc plates 1 7 are arranged below the roller 3 5 and above the roller 2 4, and the arc plates 1 7 are fixedly connected to the telescopic ends of the corresponding telescopic cylinders 6; an arc plate 2 8 is welded to the inner side of each arc plate 1 7; and a circulating conveying component is arranged on the outer side of the arc plate 1 7.

[0031] The circulation conveying assembly includes a storage box 201, a pipe 202, a water pump 203, a cooling water circulator 204 and a pipe 205; a storage box 201 is arranged on the outer side of the arc plate 7, the storage box 201 is rotatably connected to the roller 24, and the storage box 201 is set to an alloy material; the bottom of the storage box 201 is connected and fixedly connected to a pipe 202, and the pipe 202 can be set to a plastic material or an alloy material; a water pump 203 is installed on the pipe 202, and the water pump 203 is connected to the storage box The storage box 201 is bolted; a cooling water circulator 204 is bolted to the storage box 201, the input end of the cooling water circulator 204 is connected to the pipe 202, and the cooling water circulator 204 is bolted to the water pump 203; the output end of the cooling water circulator 204 is connected and fixedly connected with the pipe 2 205, the upper end of the pipe 205 is sealed and slidably connected with the corresponding arc plate 7, the cooling water circulator 204 transports the cooled water to the pipe 2 205, and the pipe 205 transports the cooled water to the inner side of the arc plate 7.

[0032] The bottom of the storage box 201 is tilted to guide water to the pipe 1 202 .

[0033] A temperature sensor is provided inside the pipe 1 202 for monitoring the temperature of water flowing into the pipe 1 202 .

[0034] The multi-stage hydraulic rod 206 is arranged above the arc plate 7, and the telescopic end of the multi-stage hydraulic rod 206 is fixedly connected to the base of the roller three 5, and the height of the roller three 5 is adjusted by the multi-stage hydraulic rod 206.

[0035] First, the left part of the cable body 9 is wound in the external unwinding mechanism, and the right end of the cable body 9 is manually passed through the mold 2, and then passed around the upper side of the roller 1 3, then passed around the lower side of the roller 2 4, and then passed around the upper side of the roller 3 5, and finally the right end of the cable body 9 is fixed in the external rewinding mechanism. At this time, the state of the cable body 9 is as follows: Figure 1 and Figure 2 As shown, then, the telescopic cylinder 6 drives the two arc plates 1 7 to move toward each other, and the arc plate 1 7 drives the two arc plates 2 8 to move toward each other, so that the two arc plates 1 7 are in contact and combined to form a round tube, and the two arc plates 2 8 are in contact and combined to form a cylinder, and the cable body 9 passes through the middle of the round tube and the cylinder. At this time, the position states of the arc plate 1 7, the arc plate 2 8 and the cable body 9 are as shown Figure 4As shown, at this time, a cavity 91 is formed between the upper part of the arc plate 28 and the inner side of the arc plate 1 7, and the storage box 201 is filled with cooling water. The water pump 203 is started, so that the cooling water in the storage box 201 flows into the cavity 91 through the pipe 1 202, the cooling water circulator 204 and the pipe 2 205 in sequence, and then flows down from the cylinder back to the storage box 201, so that the cooling water circulates in the cylinder, and then the cable body 9 is moved to the right in a taut state through the cooperation of the external unwinding mechanism and the external winding mechanism. The cable body 9 moves to the right in the mold 2, and a layer of outer skin is coated on the copper wire surface of the cable body 9 through the cooperation of the injection extruder 1 and the mold 2. When the outer skin passes through the cylinder, it is fully in contact with the cooling water in the cylinder, so that the outer skin of the cable body 9 is cooled by the cooling water. When the hot cooling water flows through the cooling water circulator 204, the cooling water is cooled by the cooling water circulator 204 to maintain its cooling performance. When in use, the rollers 2 4 and 3 5 cooperate to make the cable body 9 pass through the arc plate 1 7 and the arc plate 2 8 in a vertical state, and contact with the cooling water on the inner side of the arc plate 1 7 and the arc plate 2 8 for cooling. During this process, the cable body 9 will not contact with the arc plate 1 7 and the arc plate 2 8. While retaining the efficient cooling function of the existing device for the cable body 9, the problem of scratching the outer skin of the cable body 9 is avoided. At the same time, the cooling water in the arc plate 1 7 and the arc plate 2 8 flows downward in a pouring manner. Compared with the overflow of the cooling water in the curved corrugated pipe, the pouring method can completely discharge the heated cooling water, which is beneficial to improve the cooling effect of the cable body 9.

[0036] After the cable body 9 is converted to vertical cooling, in order to ensure the cooling effect of the cable body 9, the vertical length of the cable body 9 should be set as long as possible, that is, the distance between roller two 4 and roller three 5 is set relatively far, which makes it difficult for humans to bypass the cable body 9 from the upper side of roller three 5. Therefore, before winding the cable body 9, the multi-stage hydraulic rod 206 drives roller three 5 to move downward, lowers the height position of roller three 5, and then manually winds the cable body 9 on roller one 3, roller two 4 and roller three 5 in turn, and then tightens the cable body 9 through the cooperation of the external unwinding mechanism and the external winding mechanism, and then the multi-stage hydraulic rod 206 drives roller three 5 to move upward back to its original position, and roller three 5 drives the cable body 9 to move, so that the vertical part of the cable body 9 becomes longer, and then the cooling operation is performed. When in use, the height position of roller three 5 is adjusted by the multi-stage hydraulic rod 206, thereby avoiding the problem of manual difficulty in winding the cable body 9 due to converting the cable body 9 to vertical cooling. Example

[0037] On the basis of Example 1, Figure 4 and Figure 5As shown, it also includes an arc block 207; a plurality of arc blocks 207 are welded on the inner side of each arc plate 28, and the cooling water is guided through the arc block 207.

[0038] It also includes a guide block 208; a plurality of guide blocks 208 are welded on the inner side of each arc-shaped plate 28, and the cooling water is guided through the guide block 208.

[0039] After the cable body 9 is converted from horizontal cooling to vertical cooling, due to the limited workshop height, the vertical cooling distance is relatively small, which leads to a decrease in the cooling efficiency of the cable body 9. In order to ensure the orderly progress of the insulation layer coating process of the cable body 9, the speed at which the cable body 9 passes through the mold 2 should be kept stable. Therefore, an arc block 207 is set on the arc plate 28. When the two arc plates 208 move toward each other and combine into a cylinder, the arc plate 28 will also drive the arc block 207 to move, so that all the arc blocks 207 are combined to form a spiral sheet, and the cable body 9 passes through the middle of the spiral sheet. During the cooling process, most of the cooling water will flow downward in a spiral shape under the guidance of the arc block 207, thereby increasing the contact time between the cooling water and the cable body 9, thereby improving the cooling efficiency. When in use, the arc block 207 is combined to form a spiral sheet, and the spiral sheet guides the cooling water downward in a spiral shape, thereby increasing the contact time between the cooling water and the cable body 9, thereby improving the cooling efficiency of the cable body 9.

[0040] In order to prevent the arc block 207 from scratching the cable body 9, a certain gap is set between the arc block 207 and the cable body 9. During the cooling process, most of the cooling water will flow downward in a spiral shape under the guidance of the arc block 207, and a small amount of cooling water will still adhere to the surface of the cable body 9 and flow downward from the gap. After this part of cooling water absorbs heat, its temperature is higher than the cooling water on the arc block 207. Therefore, when the cooling water flows on the arc block 207, the cooling water flowing on the arc block 207 is guided by the guide block 208, and this part of cooling water is impacted to the surface of the cable body 9, so that the cooling water flowing on the arc block 207 and the cooling water flowing in contact with the surface of the cable body 9 are fully mixed, thereby reducing the temperature of the cooling water around the surface of the cable body 9, which is beneficial to improving the cooling efficiency. When in use, the cooling water flowing on the arc block 207 is guided to the surface of the cable body 9 by the guide block 208, which can reduce the temperature of the cooling water around the surface of the cable body 9, further improve the cooling efficiency of the cable body 9, and ensure the cooling effect. Example

[0041] On the basis of Example 2, Figure 6 and Figure 7As shown, it also includes a water absorption component; the water absorption component is connected to the arc plate 7; the water absorption component includes a sponge block 209 and an extrusion unit; each arc plate 7 is connected to a sponge block 209, and the water remaining on the surface of the cable body 9 is absorbed by the sponge block 209; the arc plate 7 is connected to the extrusion unit.

[0042] The extrusion unit includes a connecting block 2010, a slide bar 2011, a buoyancy block 2012, a pressure block 2013 and a stopper 2014; each arc plate 7 is bolted with a connecting block 2010, and the connecting block 2010 is set to a wear-resistant material; each connecting block 2010 is slidably connected to a slide bar 2011; a buoyancy block 2012 is fixedly connected to the lower end of each slide bar 2011; a pressure block 2013 is bolted to the upper end of each slide bar 2011, and the pressure block 2013 is in contact with the corresponding sponge block 209; each pressure block 2013 is provided with a plurality of circular holes, and the sponge block 209 is squeezed by the pressure block 2013; each arc plate 7 is bolted with a stopper 2014, and the stopper 2014 is fixedly connected to the corresponding sponge block 209; each sponge block 209 is in contact with the corresponding arc plate 7.

[0043] The outer surface of the injection molding extruder 1 is provided with a heat-insulating layer to reduce heat loss.

[0044] When the two arc plates 17 move toward each other and fit together, the arc plate 17 will also drive the sponge block 209 to fit the cable body 9. After the cable body 9 is cooled, it passes through the sponge block 209, and the moisture remaining on the surface of the cable body 9 is absorbed by the sponge block 209. At regular intervals, the power of the water pump 203 is increased so that the amount of cooling water transported by the pipeline 205 to the cavity 91 is greater than the amount of cooling water flowing out of the cavity 91, so that the cooling water level in the cavity 91 gradually rises and contacts with the buoyancy block 2012, so that the buoyancy block 2012 is affected by the buoyancy and drives the slide bar 2011 to slide upward on the connecting block 2010, and the slide bar 211 drives the pressing block 2013 to move upward, and the pressing block 2013 squeezes the sponge block 209 toward the stopper 2014, Part of the cooling water in the sponge block 209 is squeezed out, and the water produced by the squeezing flows out from the circular hole on the pressing block 2013 into the cavity 91, and then the power of the water pump 203 is reduced to gradually reduce the cooling water level in the cavity 91, so that the slide bar 2011, the buoyancy block 2012 and the pressing block 2013 fall back to their original positions under the action of gravity, and the sponge block 209 rebounds to its original state and regains the water absorption function. When in use, the cooling water remaining in the cable body 9 is absorbed by the sponge block 209. At the same time, the cooling water used to cool the cable body 9 is also used to drive the pressing block 2013 to move upward, so that the pressing block 2013 squeezes out part of the cooling water absorbed in the sponge block 209, eliminates the water absorption saturation state of the sponge block 209, and enables the sponge block 209 to regain the water absorption function.
