Description

Technical Field

[0001] The present application relates to the technical field of rubber strip production, and in particular to a copper wire and glass fiber conveying device for rubber strip production. Background Art

[0002] The rubber sealing strips used in automobiles contain glass fiber or copper wire, or both. Therefore, there is a conveying device at the front end of the rubber extruder to convey the glass fiber or copper wire to the rubber extruder, and then the glass fiber or copper wire is clamped inside the rubber strip to form a whole with the rubber strip.

[0003] The current method of conveying glass fiber and copper wire is to install the glass fiber roll or copper wire roll on a rotatable shaft bracket and use a rubber extruder to pull the glass fiber or copper wire and rubber into a composite.

[0004] Regarding the above-mentioned related technologies, the power for conveying glass fiber and copper wire mainly comes from the traction force of the rubber extruder. The glass fiber and copper wire are subject to large tension due to excessive stretching, which in turn causes deformation of the rubber strip formed by the composite of glass fiber or copper wire and rubber. Summary of the Invention

[0005] In order to improve the deformation degree of the rubber strip, the present application provides a copper wire and glass fiber conveying device for rubber strip production.

[0006] The present application provides a copper wire and glass fiber conveying device for rubber strip production, which adopts the following technical solution:

[0007] A copper wire and glass fiber conveying device for rubber strip production includes a frame and two rotating shafts mounted on the frame. Two adjustment mechanisms and a power transmission mechanism are also mounted on the frame. The adjustment mechanism includes a plurality of tensioning wheels arranged side by side and spaced apart. The power transmission mechanism includes a plurality of power wheels arranged side by side and spaced apart and a driving source for driving the power wheels to rotate. One power wheel is installed between two adjacent tensioning wheels. A guide assembly is also mounted on the frame. The guide assembly is located between the rotating shaft and the power wheel, and the guide assembly includes a guide wheel.

[0008] By adopting the above technical solution, the glass fiber and the copper wire are placed on the rotating shaft respectively. The glass fiber and the copper wire have the same path. The copper wire first enters the power wheel or the tensioning wheel under the guidance of the guide wheel. The power wheel and the tensioning wheel are staggered. The copper wire passes through the power wheel and the tensioning wheel in turn and finally enters the rubber extruder. In the process of the rubber extruder pulling the copper wire, the rotation of the power wheel also pushes the copper wire forward, thereby reducing the degree of pulling of the copper wire. The tensioning wheel can also tension the slack of the copper wire, thereby reducing the tension existing when the copper wire enters the rubber extruder, thereby improving the deformation degree of the rubber strip.

[0009] Optionally, a slide rail is installed on the frame, and the tensioning wheel slides up and down on the slide rail.

[0010] By adopting the above technical solution, the tensioning wheel can use its own gravity to tension the glass fiber or copper wire.

[0011] Optionally, the guide assembly further includes two guide blocks and a first elastic member for driving the two guide blocks toward each other.

[0012] By adopting the above technical solution, the weight of the copper wire roll is gradually reduced during the continuous unwinding process, the diameter of the released coils will also become smaller, the copper wire unwinding speed is accelerated, and the glass fiber or copper wire passes between the two guide blocks. The first elastic member drives the two guide blocks close to each other, and the two guide blocks have a clamping effect on the glass fiber or copper wire. When the copper wire is pulled by the extruder and the power wheel, the speed at which the copper wire enters the power transmission mechanism remains basically unchanged. Therefore, the accelerated unwinding speed of the copper wire does not easily affect the speed at which the copper wire is pulled. The tensioning effect of the tensioning wheel is also within the tensioning range, and the copper wire or glass fiber can enter the extruder at a uniform speed.

[0013] Optionally, a fixed block is installed on the frame, the first elastic member is a first spring, one end of the first spring is fixedly installed on the guide block, and the other end of the first spring is fixedly installed on the fixed block.

[0014] By adopting the above technical solution, the first spring drives the guide blocks closer to each other through its own elastic force.

[0015] Optionally, a guide rod is fixedly mounted on the guide block, the first spring is sleeved on the guide rod, and the guide rod is slidably mounted on the fixed block.

[0016] By adopting the above technical solution, the guide rod guides the first spring, causing the first spring to deform mainly along its own axial direction.

[0017] Optionally, an auxiliary mechanism is further installed on the frame, and the auxiliary mechanism includes two auxiliary blocks and a second elastic member that drives the two auxiliary blocks to approach each other, and the auxiliary blocks are located directly above the two guide blocks.

[0018] By adopting the above technical solution, after the copper wire or glass fiber passes through the two guide blocks, the copper wire continues upward through the auxiliary block and then enters the power transmission mechanism. The auxiliary block can also clamp the copper wire or glass fiber.

[0019] Optionally, a guide seat is installed on the frame, and a guide hole is opened through the guide seat for the copper wire to turn and enter the power wheel. The auxiliary block is connected with a connecting rod, and the connecting rod is rotatably installed on the fixed block. The rotation center of the connecting rod and the axis of the guide rod are parallel to each other. One end of the guide rod passes through the fixed block, and the connecting rod is provided with a through hole for the guide rod to pass through. When the two guide blocks abut each other, the guide rod leaves the connecting rod so that the connecting rod rotates under the action of gravity.

[0020] By adopting the above technical solution, when the copper wire in the copper wire roll is finished, the copper wire gradually leaves the guide block, and the two guide blocks are abutted against each other by the elastic force of the first spring. The guide rod leaves the connecting rod along with the movement of the guide block, and the connecting rod rotates downward under the action of gravity. The auxiliary block rotates with the copper wire, and the copper wire can no longer enter the power transmission mechanism smoothly after being bent. When the extruder and the power wheel pull the copper wire, the copper wire will not continue to enter the extruder. The remaining part of the copper wire is convenient for people to connect to the next roll of copper wire, and there is no need to re-wind the copper wire around the guide assembly, auxiliary mechanism, power transmission mechanism and adjustment mechanism in sequence.

[0021] Optionally, the guide block is provided with a plurality of abutment rods, and a gap is left between two adjacent abutment rods of one guide block for inserting an abutment rod of another guide block, and the guide block contacts the copper wire through the abutment rods.

[0022] By adopting the above technical solution, the setting of the abutment rod can increase the distance between the two guide blocks. When the copper wire leaves between the two guide blocks, the abutment rod of one guide block is inserted between the two abutment rods of the other guide block. The stroke of the two guide blocks approaching each other increases, and the distance between the guide blocks and the fixed block increases. Therefore, when the guide block clamps the copper wire, the end of the guide rod inserted into the connecting rod has a certain length, and the guide rod plays a more stable limiting role on the connecting rod.

[0023] Optionally, the connecting rod is connected to an additional block, the additional block is provided with a through hole, and the additional block is located directly above the auxiliary block.

[0024] By adopting the above technical solution, when the connecting rod rotates with the auxiliary block, the additional block also rotates. The additional block can also bend the copper wire, so that the copper wire has two bending points, and the auxiliary block can also better bend the copper wire.

[0025] Optionally, a preheating box is further included, which is located at one end of the frame close to the extruder. A heating part is provided in the preheating box, and through grooves are provided at opposite ends of the preheating box.

[0026] By adopting the above technical solution, when the copper wire is pulled from the frame into the extruder, it will pass through the preheating box to preheat the copper wire and glass fiber. The temperature of the copper wire and glass fiber is close to that of the extruded rubber, which can also improve the degree of deformation of the rubber strip after molding.

[0027] In summary, this application has at least one of the following beneficial effects:

[0028] 1. When the glass fiber roll or copper wire roll is unwinding, the copper wire and glass fiber can be conveyed at the same time. Both the glass fiber and the copper wire are powered by a power wheel to enter the extruder. During the conveying process, the tensioning wheel can also adjust the tension of the glass fiber or copper wire, reducing the tension of the glass fiber or copper wire when being pulled and conveyed, thereby improving the deformation of the rubber strip after molding.

[0029] 2. As the weight of the copper wire or glass fiber roll gradually decreases and the pay-off speed increases, the guide assembly not only guides the copper wire into the power transmission mechanism, but also controls the speed at which the copper wire enters the power transmission mechanism and reduces the tension of the copper wire.

[0030] 3. When the copper wire roll is empty, the auxiliary device bends the last copper wire segment to prevent the copper wire from being pulled further, making it easier for people to take on the next copper wire roll or glass fiber roll. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is combined with Figure 1-8 This application is described in further detail.

[0041] The present application discloses a copper wire and glass fiber conveying device for rubber strip production. Figure 1 A copper wire and glass fiber conveying device for rubber strip production includes a frame 1 and two rotating shafts 2 mounted on the frame 1. The rotating shafts 2 are rotatably mounted on the frame 1. The frame 1 is also equipped with two sets of adjustment mechanisms 3 and two sets of power transmission mechanisms 4. Each rotating shaft 2 corresponds to each adjustment mechanism 3 and power transmission mechanism 4. Glass fiber reels and copper wire reels are respectively mounted on the two rotating shafts 2. The two adjustment mechanisms 3 and power transmission mechanisms 4 can simultaneously convey glass fiber and copper wire.

[0042] Reference Figure 1 The power transmission mechanism 4 includes a plurality of power wheels 41 arranged side by side and a driving source for driving the power wheels 41 to rotate. The driving source can be a motor (not shown in the figure). The adjustment mechanism 3 includes a plurality of tensioning wheels 31 arranged side by side. The power wheels 41 and the tensioning wheels 31 are staggered, and a power wheel 41 is installed between two adjacent tensioning wheels 31. Before entering the rubber extruder, the copper wire passes through the power wheel 41 and the tensioning wheel 31. The power wheel 41 has a driving force to push the copper wire, and the tensioning wheel 31 has a tensioning effect on the transported copper wire. When the extruder pulls the copper wire, the copper wire is not completely pulled by the extruder, and the power wheel 41 can also provide power, so the overall tension on the copper wire is relatively low. After the copper wire enters the extruder and is compounded with the rubber to form a rubber strip, the deformation degree of the rubber strip can be improved.

[0043] A guide roller 5 is installed at one end of the frame 1 close to the extruder. The guide roller 5 has two guide grooves, so that the copper wire and the glass fiber pass through the two guide grooves side by side and enter the rubber extruder.

[0044] Reference Figure 2The frame 1 is mounted with a slide rail 6. A tensioning wheel 31 is rotatably connected to a slider 32, which slides up and down on the slide rail 6. The tensioning wheel 31 tensions the copper wire or glass fiber through its own gravity. The slide rail 6 is detachably mounted with an abutment block 61, which is threadedly connected to a bolt 62. When one end of the bolt 62 abuts the slide rail 6, the abutment block 61 is mounted on the slide rail 6, and the slider 32 abuts the abutment block 61. The downward sliding position of the slider 32 is restricted, allowing the tensioning wheel 31 to maintain a fixed position and tension the copper wire or glass fiber.

[0045] Reference Figure 3 , a guide assembly 7 is also installed on the frame 1. The guide assembly 7 includes a guide wheel 71, two guide blocks 72, and a first elastic member that drives the two guide blocks 72 to approach each other. The copper wire is guided by the guide wheel 71 and enters between the two guide blocks 72. A first elastic member is installed on each of the two guide blocks 72. The first elastic member is a first spring 73, and the first spring 73 is a compression spring. Two fixed blocks 11 are installed on the frame 1, and the two guide blocks 72 are located between the two fixed blocks 11. One end of the first spring 73 is fixedly mounted on the guide block 72, and the other end of the first spring 73 is fixedly mounted on the fixed block 11. The two first springs 73 drive the two guide blocks 72 to approach each other through their own elastic force. When the two guide blocks 72 clamp the copper wire, a gap is left between the two guide blocks 72.

[0046] A guide rod 74 is fixedly mounted on the guide block 72, and the first spring 73 is sleeved on the guide rod 74. A through hole is provided on the fixed block 11 for the guide rod 74 to pass through, and one end of the guide rod 74 passes through the fixed block 11 through the through hole. The guide rod 74 serves to limit and guide the first spring 73.

[0047] Reference Figure 4 and Figure 5 In one embodiment, an auxiliary mechanism 8 is further mounted on the frame 1 of the two guide blocks 72. The auxiliary mechanism 8 includes two auxiliary blocks 81 and a second elastic member that drives the two auxiliary blocks 81 toward each other. The two auxiliary blocks 81 are located directly above the two guide blocks 72. An extension block 82 is connected to one end of the auxiliary blocks 81 that are close to each other. The extension block 82 is provided with a half groove for glass fiber or copper wire to pass through. The two extension blocks 82 are spliced ​​together, and the direction in which the two auxiliary blocks 81 approach each other is perpendicular to the direction in which the two extension blocks 82 approach each other. The second elastic member is a second spring 83. A connecting rod 84 is connected to the auxiliary block 81. The connecting rod 84 includes a first support rod 841 and a second support rod 842 that is slidably mounted with the first support rod 841. The first support rod 841 and the second support rod 842 are perpendicular to each other. One end of the first support rod 841 is fixedly connected to the auxiliary block 81, and the end of the first support rod 841 away from the auxiliary block 81 is connected to a limit block 843. The second spring 83 is sleeved on the first support rod 841 , and one end of the second support rod 842 away from the first support rod 841 is mounted on the fixing block 11 .

[0048] Reference Figure 5 The end of the second support rod 842 away from the first support rod 841 is rotatably connected to a rotating shaft 8421. The rotating shaft 8421 is fixedly mounted on the fixed block 11. The central axis of the rotating shaft 8421 is parallel to the central axis of the guide rod 74. The second support rod 842 rotates around the rotating shaft 8421. The second support rod 842 has a through hole for the guide rod 74 to pass through. When the guide rod 74 passes through the second support rod 842, the second support rod 842 is in a vertical position, and the two auxiliary blocks 81 are in a state of clamping and guiding the copper wire.

[0049] Reference Figure 6 and Figure 7 The adjacent sides of the two guide blocks 72 are connected to a plurality of abutting rods 721, which are spaced vertically along the guide blocks 72. One end of the abutting rods 721 has an arc-shaped guide groove, and the copper wire is clamped between the guide grooves of the abutting rods 721 of the two guide blocks 72. There is space between two adjacent abutting rods 721 of one guide block 72 for the abutting rod 721 of the other guide block 72 to insert. When the copper wire is separated, the abutting rods 721 of the two guide blocks 72 approach each other, and the abutting rod 721 of one guide block 72 is inserted between the two abutting rods 721 of the other guide block 72, forming a staggered arrangement of the abutting rods 721 between the two guide blocks. The provision of the abutting rods 721 increases the distance between the two guide blocks 72, ensuring that the portion of the guide rod 74 that passes through the second support rod 842 has a certain length. When the guide rod 74 is inserted into the second support rod 842, it can provide a stable position limit for the second support rod 842.

[0050] Reference Figure 6 A guide seat 12 is installed on the frame 1. The guide seat 12 is penetrated by a guide hole for the copper wire to enter the power wheel 41. In the process of the copper wire from the auxiliary mechanism 8 to the power wheel 41, the copper wire passes through the guide hole of the guide seat 12.

[0051] Reference Figure 5 The frame 1 is equipped with a driving member for driving the second support rod 842 to rotate. The driving member is a driving spring 13. One end of the driving spring 13 is fixedly mounted on the frame 1, and the other end of the driving spring 13 is fixedly mounted on the second support rod 842.

[0052] When the copper wire on the wire coil is completely unwound and the remaining copper wire is pulled away from the two guide blocks 72, the first spring 73 quickly drives the two guide blocks 72 toward each other. The guide rod 74 moves away from the second support rod 842 as the guide rod moves, and the driving spring 13 drives the second support rod 842 to rotate away from the frame 1. The second support rod 842 rotates downward under the elastic force of the driving spring 13 and the gravity acting on the auxiliary block 81. The auxiliary block 81 rotates downward with the copper wire through the extension block 82. The copper wire between the auxiliary block 81 and the guide seat 12 is bent, making it difficult for the bent copper wire to reenter the power wheel 41. One end of the copper wire is clamped by the two auxiliary blocks 81. The remaining portion of the copper wire can be connected to a new copper wire coil, so that when replacing the copper wire coil, the copper wire does not need to be re-wound around the guide assembly 7, the auxiliary mechanism 8, the power transmission and the adjustment mechanism 3 in sequence.

[0053] Reference Figure 5 The auxiliary block 81 is connected to the additional block 85 via a rod. The additional block 85 has a through hole. The additional block 85 is located above the auxiliary block 81 and is spaced apart from the auxiliary block 81. When the connecting rod 84 rotates with the auxiliary block 81, the additional block 85 also rotates, causing the copper wire to have two bends: one between the auxiliary block 81 and the additional block 85, and the other between the additional block 85 and the guide seat 12, which can further prevent the copper wire from being pulled.

[0054] Reference Figure 8 In one embodiment, a copper wire and glass fiber conveying device for rubber strip production further includes a preheating box 9 having a through slot for the copper wire or glass fiber to pass through. A heating unit is provided within the preheating box 9. When the copper wire and glass fiber pass through the through slot, they are positioned above the heating unit, with a gap between them. Heat generated by the heating unit preheats the copper wire and glass fiber, bringing them to a similar temperature as the extruded rubber. This also reduces deformation of the formed rubber strip when the copper wire, glass fiber, and rubber are combined.

[0055] The implementation principle of the copper wire and glass fiber conveying device for rubber strip production in the embodiment of the present application is as follows:

[0056] When conveying glass fiber or copper wire, the glass fiber roll and the copper wire roll are placed on the rotating shaft 2. One end of the copper wire passes upward through the guide wheel 71, between the two guide blocks 72, between the two auxiliary blocks 81, and the additional block 85 in sequence, then turns and enters the power wheel 41 and the tension wheel 31, and finally enters the rubber extruder. When the rubber extruder pulls the copper wire, the power wheel 41 plays a power transmission role for the copper wire, so that the rubber extruder does not need to excessively pull the copper wire. The tension of the copper wire when being pulled will not be too large, and the deformation degree of the rubber strip formed by the copper wire compounding with the rubber in the rubber extruder is reduced.

[0057] The two guide blocks 72 and the two auxiliary blocks 81 have a clamping force on the copper wire or glass fiber. The pay-off speed of the copper wire roll or glass fiber roll can be controlled even after it is accelerated, so that the speed at which the copper wire or glass fiber enters the rubber extruder does not change much. When the copper wire or glass fiber is used up, the two auxiliary blocks 81 rotate downward and then bend the copper wire or glass fiber to prevent the copper wire or glass fiber from being further pulled, which can also facilitate wiring for people and eliminates the need to re-route the copper wire or glass fiber into the rubber extruder. When wiring, the tensioning wheel 31 can be slid upward so that the copper wire can be pulled back to a certain length, which can also facilitate wiring for people.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
