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 rubber insulated wire that has been cross-linked. It is usually used in situations that require 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 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 on 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 easily lead to 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.

[0009] Furthermore, the electric push rod pushes the push block to make the second indentation head fit with the outer surface of the cross-linked rubber line, and the electric control push seat pushes the first indentation head to fit with the outer surface of the cross-linked rubber line.

[0010] Furthermore, the powder transferring assembly includes a powder transferring box, a connecting pipe, a blower, a powder inlet, a powder passing tube, a second motor, a driving gear, a driven gear seat and a locking block. The top outer side of the powder transferring box is connected to a connecting pipe, and a blower is provided at the outer end of the powder transferring box. The top outer side of the blower is provided with a powder inlet, and a powder passing tube is provided between the blower and the powder transferring box. Second motors are provided on both sides of the top of the powder transferring box, and a driving gear is provided at the output end of the second motor. Driven gear seats are provided at both ends of the outside of the powder transferring box, and a locking block is arranged inside the driven gear seat.

[0011] Furthermore, the enclosing frame is connected to the powder transfer box via a connecting pipe, and the blower is connected to the powder transfer box via a powder transfer pipe.

[0012] Furthermore, the second motor drives the driving gear to rotate, and the driving gear is meshed with the driven gear seat.

[0013] Furthermore, the rotation directions of the driven gear seats on both sides outside the powder transfer box are opposite, and the engaging blocks inside the driven gear seats engage with the cross-linked rubber wire.

[0014] Furthermore, a heating seat is provided at the outer end of the powder transfer assembly, and heating patches are provided on both sides of the interior of the heating seat.

[0015] Furthermore, the heating seat is fixedly connected to the powder transfer box, and the outer surface of the heating patch is in contact with the outer surface of the cross-linked rubber line.

[0016] The present invention provides a cross-linked rubber thread powder feeding device, which has the following beneficial effects:

[0017] 1. The present invention can make hot air enter the inside of the wire sleeve through the operation of the hot air blower and blow it out from the opening of the ventilation groove, so that the hot air can enter the inside 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 first indentation head can press a longitudinal shallow mark on the surface of the cross-linked rubber wire through the operation of the electric control push seat. 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, so that the position where the longitudinal mark of the cross-linked rubber wire is pressed out can be moved to the pushing block. At this time, the electric push rod works, so that the pushing block can 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 mesh indentation on the surface of the cross-linked rubber wire. By pressing out 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 surrounding frame and the powder passing box, so that the hot air of the hot air blower can enter the inside of the powder passing box. Through this design, the rubber layer on the surface of the cross-linked rubber wire after entering the inside of the powder passing box is still in a high-temperature softened state, which makes it easier for mica powder to adhere to its surface. The 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, through the operation of the second motor, the driving gear can drive the driven gear seat to rotate. The second motors at both ends of the powder passing box rotate in opposite directions, so that when the driven gear seats on both sides drive the cross-linked rubber wire to rotate, twist marks can be twisted on the surface of the cross-linked rubber wire. 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 pressing out 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, and 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, which enables the equipment to avoid additional cooling equipment, thereby reducing the preparation cost of the equipment.

The driven gear 607 rotates, and the driving gear 607 meshes with the driven gear seat 608. The driven gear seats 608 on both sides of the outside of the powder box 601 rotate in opposite directions, and the engaging blocks 609 inside the driven gear seat 608 engage with the cross-linked rubber line 4. A heating seat 7 is provided at the outer end of the powder passing component 6, and heating patches 8 are provided on both sides of the inside 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 can be 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 works to allow hot air to enter the inside of the wire sleeve 504 and blow out from the opening of the ventilation groove 505, so that the hot air can enter the inside 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 line 4 to soften due to high temperature. At this time, the electrically controlled pushing seat 506 works, which can enable the first indentation head 507 to press a shallow longitudinal mark on the surface of the cross-linked rubber line 4. After the first indentation head 507 completes the indentation of the cross-linked rubber line 4, the electrically controlled pushing seat 506 drives the first indentation head 507 to retreat, and at the same time, the first motor 3 works to drive the cross-linked rubber line 4 to reel up, which allows the position where the longitudinal mark of the cross-linked rubber line 4 is pressed to move to the pushing block 509. At this time, the electric push rod 508 works, which can enable the pushing block 509 to drive the second indentation head 510 to press a horizontal indentation on the cross-linked rubber line 4. Through the above operations, the equipment can press a mesh indentation on the surface of the cross-linked rubber line 4, and by pressing 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 powder 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 up, 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 through the blower 603, so that the mica powder can 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, 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 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 lock and fix the cross-linked rubber line 4, and 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 turn 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, and the design of pressing out a mesh indentation,It can make the twist marks easier to form, which can avoid the situation where the cross-linked rubber line 4 is damaged due to excessive twisting force. The cross-linked rubber line 4 that has been powdered can enter the heating seat 7 as the winding seat 2 is wound. The heating patch 8 inside the heating seat 7 can be completely fitted with the rubber layer on the outer surface of the cross-linked rubber line 4. Through the heating of the heating patch 8, the twist marks and indentations on the surface of the cross-linked rubber line 4 can be eliminated, and the mica powder attached to the surface of the cross-linked rubber line 4 will melt to the surface of the cross-linked rubber line 4 due to the reshaping of the cross-linked rubber line 4, which can further enhance the adhesion effect of the mica powder and the cross-linked rubber line 4. Because the equipment adopts intermittent segment-type powdering for the cross-linked rubber line 4, the cross-linked rubber line 4 that has been reshaped by the heating patch 8 can be automatically cooled and solidified in the air after being removed from the heating seat 7 and wound up by the winding seat 2, which enables the equipment to avoid additional cooling equipment, thereby reducing the preparation cost of the equipment.

[0030] In summary, when the cross-linked rubber thread powdering device is used, 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, and the staff passes the pulled cross-linked rubber thread 4 through the wire sleeve 504, the surrounding frame 501, and makes the cross-linked rubber thread 4 pass 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, and 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 the 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. 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, so that the rubber layer on the surface of the cross-linked rubber wire 4 can be softened due to high temperature. At this time, the first indentation head 507 can press a shallow longitudinal mark on the surface of the cross-linked rubber wire 4 through the operation of the electrically controlled push seat 506. After the first indentation head 507 has completed indenting the cross-linked rubber wire 4, the electric The control push seat 506 drives the first indentation head 507 to retreat, 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, so that the push block 509 can 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 mesh indentation on the surface of the cross-linked rubber cord 4. By pressing out the indentation, 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 has completed 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 works, the staff puts mica powder into the powder inlet 604, and the blower 603 works, 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 surrounding frame 501 with the powder box 601, so that the hot air of 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 after entering the inside of the powder box 601 is still in a high-temperature softened state, which makes it easier for the mica powder to adhere 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;

[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, and 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, so that when the driven gear seats 608 on both sides drive the cross-linked rubber cord 4 to rotate, twist marks can be formed 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 pressing out 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. The twist marks and indentations on the surface of the cross-linked rubber wire 4 can be eliminated by heating with the heating patch 8, 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 be automatically cooled and solidified in the air and wound up by the winding seat 2, which enables the equipment to avoid additional cooling equipment, thereby reducing the preparation cost of the equipment.
