Description

Technical Field

[0001] The invention relates to the technical field of rubber thread production, in particular to a cross-linked rubber thread powder feeding device. Background Art

[0002] Cross-linked rubber wire is a cross-linked rubber insulated wire, usually used in situations requiring high heat resistance, chemical resistance, weather resistance and good electrical insulation performance. During the production process of cross-linked rubber wire, covalent bonds (cross-linking bonds) are formed between the rubber molecular chains through specific chemical or physical methods, thereby significantly improving the physical properties and environmental resistance of the rubber. Cross-linked rubber wire usually needs to be powdered during the production process. Powdering refers to applying powders such as talcum powder or mica powder to the surface of the cross-linked rubber wire. Its main purpose is to prevent rubber products from adhesion, deformation and other problems during storage and transportation, and to improve the appearance and performance of the product.

[0003] The common cross-linked rubber thread powdering devices on the market may have poor powdering effects during use due to factors such as the cross-linked rubber thread surface being too smooth, the poor adhesion of talcum powder or mica powder, etc.

[0007] Furthermore, the hot air blower is connected to the ventilation groove through the wire sleeve, and the ventilation groove is distributed in a ring shape inside the wire sleeve.

[0008] Further, the electric control pushing base pushes the first indentation head to displace, and the first indentation head is annular in the inside of the wire passing sleeve.

[0009] Further, the electric pushing rod pushes the pushing block to make the second indentation head fit the outer surface of the crosslinked rubber wire, and the electric control pushing base pushes the first indentation head to fit the outer surface of the crosslinked rubber wire.

[0010] Further, the powder passing assembly comprises a powder passing box, a communication pipe, a blower, a powder inlet, a powder passing pipe, a second motor, a driving gear, a driven gear base and a clamping block, the top outer side of the powder passing box is connected with the communication pipe, the outer end of the powder passing box is provided with the blower, the top outer side of the blower is provided with the powder inlet, the blower and the powder passing box are provided with the powder passing pipe, the top two sides of the powder passing box are provided with the second motor, the output end of the second motor is provided with the driving gear, the outer two ends of the powder passing box are provided with the driven gear base, and the inside of the driven gear base is arranged with the clamping block.

[0011] Further, the surrounding frame is communicated with the powder passing box through the communication pipe, and the blower is communicated with the powder passing box through the powder passing pipe.

[0012] Further, the second motor drives the driving gear to rotate, and the driving gear is engaged with the driven gear base.

[0013] Further, the rotation directions of the driven gear bases on the two outer sides of the powder passing box are opposite, and the clamping block in the inside of the driven gear base clamps the crosslinked rubber wire.

[0014] Further, the outer end of the powder passing assembly is provided with a heating base, and the inside of the heating base is provided with heating patches on two sides.

[0015] Further, the heating base is fixedly connected with the powder passing box, and the outer surface of the heating patch is fitted with the outer surface of the crosslinked rubber wire.

[0016] The crosslinked rubber wire powder passing device has the following beneficial effects:

[0017] 1. The present invention works by a hot air blower, which can make hot air enter the interior of the wire sleeve and blow it out from the opening of the ventilation groove, so that the hot air can enter the interior of the surrounding frame. When the hot air flows inside the wire sleeve, its heat can be radiated to the cross-linked rubber wire at the middle end of the wire sleeve, so that the rubber layer on the surface of the cross-linked rubber wire can be softened due to high temperature. At this time, the electric control push seat works, which can make the first indentation head press out a longitudinal shallow mark on the surface of the cross-linked rubber wire. After the first indentation head completes the indentation of the cross-linked rubber wire, the electric control push seat drives the first The indentation head retracts, and at the same time the first motor works to drive the cross-linked rubber wire to reel up, which enables the position where the longitudinal mark of the cross-linked rubber wire is pressed to move to the pushing block. At this time, the electric push rod works, which enables the pushing block to drive the second indentation head to press a horizontal indentation on the cross-linked rubber wire. Through the above operations, the equipment can press a network indentation on the surface of the cross-linked rubber wire. By pressing the indentation, the contact area between the mica powder and the cross-linked rubber wire in the subsequent powdering process can be increased, which can greatly improve the powdering uniformity of the cross-linked rubber wire and the adhesion density of the mica powder.

[0018] 2. The connecting pipe of the present invention can connect the enclosing frame and the powder passing box, which allows the hot air from the hot air blower to enter the inside of the powder passing box. Through this design, the rubber layer on the surface of the cross-linked rubber wire is still in a high-temperature softened state after entering the inside of the powder passing box, which makes it easier for mica powder to adhere to its surface. This design can make full use of the heat of the hot air blower, which can improve the energy-saving performance of the equipment. In addition, during the powder passing process, the locking block inside the driven gear seat can lock and fix the cross-linked rubber wire. At the same time, the second motor is operated to make the driving gear drive the driven gear seat to rotate. The second motors at both ends of the powder passing box rotate in opposite directions, which makes the driven gear seats on both sides drive the cross-linked rubber wire to rotate, which can make the surface of the cross-linked rubber wire twist marks. The generation of twist marks can further improve the surface roughness of the cross-linked rubber wire, which further improves the adhesion of mica powder to the surface of the cross-linked rubber wire. The design of extruding a mesh indentation can make twist marks easier to form, which can avoid the situation where the cross-linked rubber wire is damaged due to excessive twisting force.

[0019] 3. The cross-linked rubber wire that has been powdered in the present invention can enter the interior of the heating seat as the winding seat is wound. The heating patch inside the heating seat can completely fit with the rubber layer on the outer surface of the cross-linked rubber wire. The twist marks and indentations on the surface of the cross-linked rubber wire can be eliminated by heating with the heating patch, and the mica powder attached to the surface of the cross-linked rubber wire will melt to the surface of the cross-linked rubber wire due to the reshaping of the cross-linked rubber wire, which can further enhance the adhesion effect of the mica powder and the cross-linked rubber wire. Since the equipment adopts intermittent segment-type powdering for the cross-linked rubber wire, the cross-linked rubber wire that has been reshaped by the heating patch can be automatically cooled and solidified in the air after being removed from the interior of the heating seat and then wound up by the winding seat. This enables the equipment to avoid additional cooling equipment, thereby reducing the preparation cost of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The driven gear 607 rotates, and the driving gear 607 is meshed with the driven gear seat 608. The rotation directions of the driven gear seats 608 on both sides of the powder box 601 are opposite, and the engaging blocks 609 inside the driven gear seat 608 are engaged with the cross-linked rubber line 4. The outer end of the powder passing component 6 is provided with a heating seat 7, and heating patches 8 are provided on both sides of the interior of the heating seat 7. The heating seat 7 is fixedly connected to the powder box 601, and the outer surface of the heating patch 8 is in contact with the outer surface of the cross-linked rubber line 4.

[0029] The specific operation is as follows: the staff pulls the cross-linked rubber wire 4 wound on the outer end of the winding seat 2 to make it wind out from the surface of the winding seat 2; the staff passes the pulled cross-linked rubber wire 4 through the wire sleeve 504, the surrounding frame 501, and passes the cross-linked rubber wire 4 through the powder box 601 and the heating seat 7, so that the cross-linked rubber wire 4 is fixed to the winding seat 2 at the other end of the base 1; at this point, the initial arrangement of the cross-linked rubber wire 4 is completed; after the initial arrangement of the cross-linked rubber wire 4 is completed, the hot air blower 503 is operated to allow hot air to enter the interior of the wire sleeve 504 and blow out from the opening of the ventilation groove 505, so that the hot air can enter the interior of the surrounding frame 501, and when the hot air flows inside the wire sleeve 504, its heat can be radiated to the cross-linked rubber wire 4 at the middle end of the wire sleeve 504 This allows the rubber layer on the surface of the cross-linked rubber wire 4 to soften due to high temperature. At this time, the electric-controlled push seat 506 is operated to enable the first indentation head 507 to press out a shallow longitudinal mark on the surface of the cross-linked rubber wire 4. After the first indentation head 507 completes the indentation of the cross-linked rubber wire 4, the electric-controlled push seat 506 drives the first indentation head 507 to retract. At the same time, the first motor 3 works to drive the cross-linked rubber wire 4 to reel up, which enables the position where the cross-linked rubber wire 4 presses out the longitudinal mark to move to the push block 509. At this time, the electric push rod 508 is operated to enable the push block 509 to drive the second indentation head 510 to press out a horizontal indentation on the cross-linked rubber wire 4. Through the above operations, the equipment can press out a mesh indentation on the surface of the cross-linked rubber wire 4. By pressing out the indentation, the cloud in the subsequent powdering process can be improved. The contact area between the mother powder and the cross-linked rubber wire 4 can greatly improve the powdering uniformity of the cross-linked rubber wire 4 and the adhesion density of the mica powder. After the cross-linked rubber wire 4 completes the indentation, the first motor 3 works again to drive the winding seat 2 to reel, so that the cross-linked rubber wire 4 can be moved to the inside of the powder box 601. Before the equipment works, the staff puts mica powder into the powder inlet 604 and works the blower 603 to make the mica powder enter the powder box 601 through the powder pipe 605, and the connecting pipe 602 can connect the enclosing frame 501 with the powder box 601, which allows the hot air from the hot air blower 503 to enter the inside of the powder box 601. Through this design, the rubber layer on the surface of the cross-linked rubber wire 4 after entering the powder box 601 is still in a high-temperature softened state, which makes The mica powder can be more easily attached to its surface, and this design can make full use of the heat of the hot air blower 503, which can improve the energy-saving performance of the equipment. In addition, during the powdering process, the locking block 609 inside the driven gear seat 608 can be locked and fixed to the cross-linked rubber line 4. At the same time, the second motor 606 works to enable the driving gear 607 to drive the driven gear seat 608 to rotate. The second motors 606 at both ends of the powder box 601 rotate in opposite directions, which makes the driven gear seats 608 on both sides drive the cross-linked rubber line 4 to rotate, which can make the surface of the cross-linked rubber line 4 twist marks. The generation of twist marks can further improve the surface roughness of the cross-linked rubber line 4, which further improves the adhesion of mica powder to the surface of the cross-linked rubber line 4. The design of pressing out a mesh indentation,It can make twist marks easier to form, which can avoid the situation where the cross-linked rubber cord 4 is damaged due to excessive twisting force. The cross-linked rubber cord 4 that has been powdered can enter the interior of the heating seat 7 as the winding seat 2 is wound. The heating patch 8 inside the heating seat 7 can completely fit with the rubber layer on the outer surface of the cross-linked rubber cord 4. Through the heating of the heating patch 8, the twist marks and indentations on the surface of the cross-linked rubber cord 4 can be eliminated, and the mica powder attached to the surface of the cross-linked rubber cord 4 will melt to the surface of the cross-linked rubber cord 4 due to the reshaping of the cross-linked rubber cord 4, which can further improve the adhesion effect of the mica powder and the cross-linked rubber cord 4. Because the equipment adopts intermittent segmented powdering for the cross-linked rubber cord 4, the cross-linked rubber cord 4 that has been reshaped by the heating patch 8 can be automatically cooled and solidified in the air after being removed from the interior of the heating seat 7 and then wound up by the winding seat 2. This eliminates the need for additional cooling equipment, thereby reducing the preparation cost of the equipment.

[0030] In summary, when using the cross-linked rubber thread powdering device, the staff first pulls the cross-linked rubber thread 4 wound on the outer end of the winding seat 2 to make it wind out from the surface of the winding seat 2. The staff then passes the pulled cross-linked rubber thread 4 through the wire sleeve 504, the surrounding frame 501, and the cross-linked rubber thread 4 through the powder box 601 and the heating seat 7, so that the cross-linked rubber thread 4 can be fixed to the winding seat 2 at the other end of the base 1. At this point, the initial layout of the cross-linked rubber thread 4 is completed;

[0031] Then, after the initial arrangement of the cross-linked rubber wire 4 is completed, the hot air blower 503 is operated to allow hot air to enter the interior of the wire sleeve 504 and be blown out from the opening of the ventilation groove 505, which allows the hot air to enter the interior of the surrounding frame 501. When the hot air flows inside the wire sleeve 504, its heat can be radiated to the cross-linked rubber wire 4 at the middle end of the wire sleeve 504, which allows the rubber layer on the surface of the cross-linked rubber wire 4 to soften due to high temperature. At this time, the electric control push seat 506 is operated to enable the first indentation head 507 to press out a longitudinal shallow mark on the surface of the cross-linked rubber wire 4. After the first indentation head 507 completes the indentation of the cross-linked rubber wire 4, the electric control push seat 506 is operated. The control push seat 506 drives the first indentation head 507 to retract, and at the same time the first motor 3 works to drive the cross-linked rubber cord 4 to reel up, so that the position where the cross-linked rubber cord 4 is pressed out with a longitudinal mark can be moved to the push block 509. At this time, the electric push rod 508 works, which can enable the push block 509 to drive the second indentation head 510 to press a horizontal indentation on the cross-linked rubber cord 4. Through the above operation, the equipment can press out a network of indentations on the surface of the cross-linked rubber cord 4. By pressing out the indentations, the contact area between the mica powder and the cross-linked rubber cord 4 in the subsequent powdering process can be increased, which can greatly improve the powdering uniformity of the cross-linked rubber cord 4 and the adhesion density of the mica powder.

[0032] After the cross-linked rubber wire 4 completes the indentation, the first motor 3 works again to drive the winding seat 2 to reel up, so that the cross-linked rubber wire 4 can be moved to the inside of the powder box 601. Before the equipment is put into operation, the staff puts mica powder into the powder inlet 604 and operates the blower 603, so that the mica powder can enter the inside of the powder box 601 through the powder pipe 605, and the connecting pipe 602 can connect the enclosing frame 501 with the powder box 601, so that the hot air from the hot air blower 503 can enter the inside of the powder box 601. Through this design, the rubber layer on the surface of the cross-linked rubber wire 4 is still in a high-temperature softened state after entering the powder box 601, which makes it easier for the mica powder to adhere to its surface. Moreover, this design can make full use of the heat of the hot air blower 503, which can improve the energy-saving performance of the equipment.

[0033] During the powdering process, the engaging block 609 inside the driven gear seat 608 can engage and fix the cross-linked rubber cord 4. At the same time, the second motor 606 works to enable the driving gear 607 to drive the driven gear seat 608 to rotate. The second motors 606 at both ends of the powdering box 601 rotate in opposite directions. This makes the driven gear seats 608 on both sides drive the cross-linked rubber cord 4 to rotate, which can cause twist marks on the surface of the cross-linked rubber cord 4. The generation of twist marks can further improve the surface roughness of the cross-linked rubber cord 4, which further improves the adhesion of mica powder to the surface of the cross-linked rubber cord 4. The design of extruding a mesh indentation can make the twist marks easier to form, which can avoid the situation where the cross-linked rubber cord 4 is damaged due to excessive twisting force.

[0034] Finally, the cross-linked rubber wire 4 that has been powdered can enter the interior of the heating seat 7 as the winding seat 2 is wound. The heating patch 8 inside the heating seat 7 can completely fit with the rubber layer on the outer surface of the cross-linked rubber wire 4. Through the heating of the heating patch 8, the twist marks and indentations on the surface of the cross-linked rubber wire 4 can be eliminated, and the mica powder attached to the surface of the cross-linked rubber wire 4 will melt to the surface of the cross-linked rubber wire 4 due to the reshaping of the cross-linked rubber wire 4, which can further enhance the adhesion effect of the mica powder and the cross-linked rubber wire 4. Because the equipment adopts intermittent segment-type powdering for the cross-linked rubber wire 4, the cross-linked rubber wire 4 that has been reshaped by the heating patch 8 is removed from the interior of the heating seat 7 and can automatically cool and solidify in the air and be wound up by the winding seat 2. This enables the equipment to eliminate additional cooling equipment, thereby reducing the preparation cost of the equipment.
