Description

Technical Field

[0001] This application relates to the technical field of fuel tank straps, and in particular to a fuel tank strap processing device. Background Technology

[0002] Car fuel tanks are usually secured using fuel tank straps, which firmly fasten the fuel tank to the car body.

[0003] In related technologies, a fuel tank strap has been designed, referring to... Figure 1 It includes a rubber sleeve 9 and a rubber band 91; when in use, the operator uses their fingers to open the rubber sleeve 9 and then inserts the rubber band 91 into the inside of the rubber sleeve 9 to complete the installation of the fuel tank strap.

[0004] Regarding the aforementioned technologies, the inventors believe that when workers install rubber sleeves and rubber bands, they need to sequentially expand the rubber sleeves along their length before inserting the rubber bands into the expanded areas. Furthermore, since the rubber sleeves themselves are made of rubber and have a certain degree of elasticity, they are not easy to fix in place, which can lead to workers consuming a lot of working time. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the work efficiency of staff, this application provides a fuel tank strapping processing device.

[0006] This application provides a fuel tank strapping processing device, which adopts the following technical solution:

[0007] A fuel tank strapping device includes a frame with rotating rods rotatably connected to both ends. A conveyor belt is sleeved on the two rotating rods for conveying a rubber sleeve. A rotating motor is mounted on the frame, and the output end of the rotating motor is connected to one of the rotating rods. A belt winding component is mounted on the frame for driving the rubber belt to release. A spreading component is mounted on the frame for spreading the rubber sleeve so that the rubber belt can be inserted into the rubber sleeve.

[0008] By adopting the above technical solution, a portion of the rubber sleeve is first placed on the conveyor belt. Then, the rubber sleeve is opened by the spreading component, and the rubber belt is released by the winding component, allowing it to be inserted into the rubber sleeve. Finally, the rotating motor is started, which drives the rotating rod to rotate. The rotating rod moves the conveyor belt, which in turn moves the rubber sleeve, thus completely embedding the entire rubber belt into the rubber sleeve. This eliminates the need for workers to manually spread the rubber belt along its length and insert it into the rubber sleeve, effectively improving the work efficiency of the workers.

[0009] Preferably, the winding component includes two connecting rods, a winding rod, and a winding motor. The two connecting rods are symmetrically arranged on the side wall of the frame. The winding rod is rotatably connected to the two connecting rods. The winding motor is located on the side wall of one of the connecting rods, and the output end of the winding motor is connected to the winding rod.

[0010] By adopting the above technical solution, the winding motor is started, which drives the winding rod to rotate, so that the rubber belt is released from the winding rod and moves to the rubber sleeve. This eliminates the need for workers to manually put the rubber belt into the expanded rubber sleeve, effectively improving the work efficiency of the workers.

[0011] Preferably, the spreading assembly includes an auxiliary rod, two moving blocks, two connecting rods, two spreading rods, two positioning rods, and a moving component. The auxiliary rod is disposed on the side wall of the frame, and a moving groove is formed on the side of the auxiliary rod near the conveyor belt. The two moving blocks are slidably connected to the inner wall of the moving groove. The two connecting rods and the two moving blocks are correspondingly disposed, and the two connecting rods are rotatably connected to the side wall of the corresponding moving block. The two connecting rods are rotatably connected to each other. The two connecting rods and the two spreading rods are correspondingly disposed, and the two spreading rods are rotatably connected to the end of the corresponding connecting rod near the conveyor belt. The two positioning rods and the two spreading rods are correspondingly disposed, and the two positioning rods are disposed on the side wall of the corresponding spreading rod. Both positioning rods are slidably connected to the frame. The moving component is used to drive the two moving blocks to move towards or away from each other in the horizontal direction along the inner wall of the moving groove.

[0012] By adopting the above technical solution, the moving component drives two moving blocks to move horizontally along the inner wall of the moving groove towards opposite sides. The two moving blocks drive the spreading rod to move synchronously through the connected docking rod. At this time, the positioning rod moves synchronously along the frame so that the rubber sleeve can be spread open by the two spreading rods, thereby realizing the insertion of the rubber strip into the rubber sleeve.

[0013] Preferably, the moving component includes a bidirectional lead screw, a fixed rod, and a locking sleeve. The bidirectional lead screw is rotatably connected to the inside of the moving groove. Two moving blocks are threaded onto the side wall of the bidirectional lead screw. The fixed rod is located at the end of the bidirectional lead screw. The side wall of the auxiliary rod has a fixing groove for the fixed rod to rotate. The locking sleeve is threaded onto the side wall of the fixed rod, and the end of the locking sleeve is threaded into the inner wall of the fixing groove.

[0014] By adopting the above technical solution, the operator rotates the bidirectional lead screw, which drives the two moving blocks to move towards each other or away from each other. When the spreading block spreads the rubber sleeve, the locking sleeve is rotated along the side wall of the fixing rod until the end thread of the locking sleeve is embedded in the inner wall of the fixing groove, thereby fixing the bidirectional lead screw and improving the stability after the spreading block spreads the rubber sleeve.

[0015] Preferably, each of the two supporting rods is provided with an insert rod on the opposite side, and the side wall of the insert rod is rotatably connected with an anti-wear ring.

[0016] By adopting the above technical solution, when the conveyor belt drives the rubber sleeve to move, the rubber sleeve drives the anti-wear ring to rotate due to the contact between the anti-wear ring and the rubber sleeve, thereby reducing the frictional resistance between the support rod and the anti-wear ring, and thus reducing the possibility of damage to the rubber sleeve.

[0017] Preferably, the auxiliary rod has a mounting rod on its side wall, a push rod is rotatably connected to the side wall of the mounting rod, an assist rod is provided at the end of the push rod away from the auxiliary rod, and a lifting component is provided on the mounting rod to drive the assist rod to reciprocate in the vertical direction.

[0018] By adopting the above technical solution, the lifting component drives the push rod to swing back and forth. The push rod drives the assist rod to move back and forth vertically, thereby generating a pushing force on the rubber belt through the assist rod, so that the rubber belt can be stably inserted into the rubber sleeve.

[0019] Preferably, the lifting component includes a lifting motor, a lifting ring, and a sliding rod. The lifting motor is disposed on the side wall of the mounting rod, the lifting ring is disposed at the output end of the drive motor, and the sliding rod is disposed at the end of the push rod away from the assist rod. The side wall of the lifting ring is provided with a wave-shaped sliding groove along the circumference for the sliding rod to move.

[0020] By adopting the above technical solution, the lifting motor is started, which drives the lifting ring to rotate. The lifting ring drives the sliding rod to move along the inner wall of the wave sliding groove. The sliding rod drives the push rod to swing back and forth, thus eliminating the need for workers to manually drive the push rod to swing, thereby improving the work efficiency of the workers.

[0021] Preferably, stabilizing rods are provided on both sides of the frame, and abutting rods are provided on the opposite sides of the two stabilizing rods. Both abutting rods are slidably connected to the frame. A first moving rod is provided on the side wall of one abutting rod, and a second moving rod is provided on the side wall of the other abutting rod. The first moving rod and the second moving rod are slidably connected to the frame. A driving component is provided on the frame to drive the first moving rod and the second moving rod to move towards each other or away from each other.

[0022] By adopting the above technical solution, the driving component drives the first moving rod and the second moving rod to move toward each other. The first moving rod and the second moving rod drive the stabilizing rod to move toward each other through the connected abutting rod, so that the two abutting rods abut against the side wall of the rubber sleeve, thereby limiting the movement position of the rubber sleeve on the conveyor belt, and thus reducing the possibility of the rubber sleeve detaching from the conveyor belt during its movement.

[0023] Preferably, the driving component includes a support rod, a drive motor, a gear, and two racks. The support rod is disposed on the side wall of the frame, the drive motor is disposed on the side wall of the support rod, the gear is disposed at the output end of the drive motor, and both racks mesh with the gear. One rack is disposed on the side wall of the first moving rod, and the other rack is disposed on the side wall of the second moving rod.

[0024] By adopting the above technical solution, the drive motor is started, which drives the gear to rotate. The gear drives the two racks to move in opposite directions at the same time, thereby driving the first moving rod and the second moving rod to move in opposite directions at the same time, so as to achieve the contact between the stabilizing rod and the side wall of the rubber sleeve.

[0025] Preferably, extrusion rods are provided on both sides of the frame, and extrusion rollers are rotatably connected to the side walls of the two extrusion rods.

[0026] By adopting the above technical solution, when the rubber belt is inserted into the rubber sleeve, the whole formed by the rubber belt and the rubber sleeve moves synchronously along the conveyor belt. When the whole formed by the rubber belt and the rubber sleeve moves synchronously between the extrusion roller and the conveyor belt, the extrusion roller extrudes the whole formed by the rubber belt and the rubber sleeve, which further improves the stability of the rubber belt inserted into the rubber sleeve.

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

[0028] 1. First, place a portion of the rubber sleeve on the conveyor belt. Then, the rubber sleeve is opened by the spreading component. Next, the rubber belt is released by the winding component, allowing it to be inserted into the rubber sleeve. Finally, the rotating motor is started, which drives the rotating rod to rotate. The rotating rod moves the conveyor belt, which in turn moves the rubber sleeve, thus completely embedding the entire rubber belt into the rubber sleeve. This eliminates the need for workers to manually spread the rubber belt along its length and insert it into the rubber sleeve, effectively improving the work efficiency of the workers.

[0029] 2. The lifting component drives the push rod to swing back and forth. The push rod drives the assist rod to move back and forth vertically, thereby generating a pushing force on the rubber belt through the assist rod, so that the rubber belt is stably embedded inside the rubber sleeve.

[0038] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0039] This application discloses a fuel tank strap processing device. (Refer to...) Figure 2 and Figure 3The fuel tank strapping device includes a frame 1, with rotating rods 11 rotatably connected to both ends of the frame 1. A conveyor belt 111 is fitted on the two rotating rods 11 to transport the rubber sleeve, so that the rubber sleeve moves in the horizontal direction. A rotating motor 12 is bolted to the side wall of the frame 1, and the output end of the rotating motor 12 is bolted to the side wall of one of the rotating rods 11.

[0040] Reference Figure 2 The frame 1 is equipped with a winding component 2 for driving the release of the wound rubber belt 91; the frame 1 is also equipped with a spreading component 3 for spreading the rubber sleeve. After the spreading component 3 spreads the rubber sleeve, the rubber belt is moved to the spread rubber sleeve by the winding component 2, and the rubber belt 91 inserts into the rubber sleeve under its own weight; then the rotating motor 12 is started, which drives the rotating rod 11 to rotate, and the rotating rod 11 drives the conveyor belt 111 to move, so that the entire rubber belt is completely inserted into the entire rubber sleeve, thus eliminating the need for workers to manually insert the entire rubber belt into the entire rubber sleeve, effectively improving the work efficiency of workers.

[0041] Reference Figure 3 The winding component 2 includes two connecting rods 21, a winding rod 22, and a winding motor 23. The two connecting rods 21 are symmetrically welded to the side wall of the frame 1, and both connecting rods 21 are inclined relative to the frame 1. The winding rod 22 is rotatably connected to the side wall of the two connecting rods 21. The winding motor 23 is bolted to the side wall of one of the connecting rods 21, and the output end of the winding motor 23 is bolted to the winding rod 22. This allows the operator to start the winding motor 23, which drives the winding rod 22 to rotate, thereby releasing the rubber belt wound on the winding rod 22.

[0042] Reference Figure 4 and Figure 5 The expansion assembly 3 includes an auxiliary rod 31, two moving blocks 32, two connecting rods 33, two expansion rods 34, two positioning rods 35, and a moving part 36. The auxiliary rod 31 is welded to the frame 1. The auxiliary rod 31 has a moving groove 311 on the side near the conveyor belt 111 for the two moving blocks 32 to slide. The two connecting rods 33 and the two moving blocks 32 are arranged in a one-to-one correspondence. The two connecting rods 33 are rotatably connected to the side wall of the corresponding moving block 32 and are hinged to each other. The two expansion rods 34 and the two connecting rods 33 are arranged in a one-to-one correspondence. The two expansion rods 34 are rotatably connected to the end of the corresponding connecting rod 33. The two positioning rods 35 and the two expansion rods 34 are arranged in a one-to-one correspondence. The two positioning rods 35 are welded to the side wall of the corresponding expansion rod 34 and are slidably connected to the frame 1.

[0043] Reference Figure 5The movable component 36 includes a bidirectional lead screw 361, a fixed rod 362, and a locking sleeve 363. The bidirectional lead screw 361 is rotatably connected to the inner wall of the movable groove 311. Two movable blocks 32 are respectively threaded to the ends of the bidirectional lead screw 361. The fixed rod 362 is welded to the end wall of the bidirectional lead screw 361. The side wall of the auxiliary rod 31 is provided with a fixed groove 13 for the fixed rod 362 to rotate. The locking sleeve 363 is threaded onto the side wall of the fixed rod 362, and the end of the locking sleeve 363 is threaded into the inner wall of the fixed groove 13. When the operator rotates the bidirectional lead screw 361, the two moving blocks 32 move along the inner wall of the moving groove 311 toward opposite sides. The two moving blocks 32 drive the corresponding spreading rods 34 to move simultaneously through the connected docking rods 33. At this time, the positioning rods 35 on the side wall of the spreading rods 34 move synchronously along the frame 1 until the spreading rods 34 spread the rubber sleeve. Then, the locking sleeve 363 is rotated, causing the locking sleeve 363 to rotate along the side wall of the fixing rod 362 until the end of the locking sleeve 363 is threaded into the inner wall of the fixing groove 13, thereby fixing the bidirectional lead screw 361 and improving the stability of the spreading rods 34 when spreading the rubber sleeve.

[0044] Reference Figure 4 Each of the two support rods 34 has a welded insertion rod 341 on one side facing away from each other. In this embodiment, the insertion rod 341 is an L-shaped rod, and an anti-wear ring 3411 is rotatably connected to the side wall of the insertion rod 341. When the conveyor belt 111 drives the rubber sleeve to move in the horizontal direction, the rubber sleeve drives the anti-wear ring 3411 to rotate. At this time, the anti-wear ring 3411 generates a thrust to push the rubber sleeve, which can effectively reduce the possibility that the support rod 34 will jam the rubber sleeve, making the rubber sleeve unable to move.

[0045] Reference Figure 2 A lifting component 5 is provided on the auxiliary rod 31. The lifting component 5 includes a lifting motor 51, a lifting ring 52, and a sliding rod 53. The lifting motor 51 is bolted to the side of the auxiliary rod 31 near the conveyor belt 111. The lifting ring 52 is welded and sleeved on the output end of the lifting motor 51. The side wall of the lifting ring 52 has a wave sliding groove 521 along the circumferential wall for the sliding rod 53 to slide circumferentially. A push rod 41 is rotatably connected to the side wall of the sliding rod 53. An assist rod 41 is welded to the end of the push rod 41 away from the sliding rod 53. An installation rod 4 is rotatably connected to the side wall of the push rod 41. The installation rod 4 and the auxiliary rod 31 are welded and fixed.

[0046] Reference Figure 2When the expansion rod 34 expands the rubber sleeve, the lifting motor 51 is started. The lifting motor 51 drives the lifting ring 52 to rotate. The lifting ring 52 drives the sliding rod 53 to move along the inner wall of the wave sliding groove 521. At this time, the push rod 41 swings back and forth on the mounting rod 4 under the action of the sliding rod 53. The push rod 41 drives the assist rod 411 to move back and forth in the vertical direction, thereby striking the rubber strip embedded in the rubber sleeve and improving the stability of the rubber strip inserted into the rubber sleeve.

[0047] Reference Figure 3 Both sides of the frame 1 are provided with extrusion rods 8, and the side walls of the two extrusion rods 8 are rotatably connected to extrusion rollers 81. When the whole formed by the rubber belt and the rubber sleeve moves synchronously between the extrusion rollers 81 and the conveyor belt 111, the extrusion rollers 81 extrude the whole formed by the rubber belt and the rubber sleeve again, which further improves the stability of the rubber belt inserted into the rubber sleeve.

[0048] Reference Figure 6 A drive unit 7 is provided on the frame 1. The drive unit 7 includes a support rod 71, a drive motor 72, a gear 73, and two racks 74. The support rod 71 is welded to the side wall of the frame 1. The drive motor 72 is bolted to the side wall of the support rod 71. The gear 73 is welded and sleeved on the output end of the drive motor 72. Both racks 74 mesh with the gear 73 and are symmetrically arranged on both sides of the gear 73. A first moving rod 611 is welded to the end wall of one rack 74, and a second moving rod 612 is welded to the end wall of the other rack 74. The first moving rod 611 and the second moving rod 612 are slidably connected to the frame 1. Abutment rods 61 are welded to the opposite sides of the first moving rod 611 and the two abutment rods 61 are slidably connected to the frame 1. Stabilizing rods 6 are welded to the sides of the two abutment rods 61 that are close to each other. The two stabilizing rods 6 are slidably connected to the upper side of the conveyor belt 111. This allows the operator to start the drive motor 72, which in turn drives the gear 73 to rotate. The gear 73 then drives the two racks 74 to move toward each other, causing the first moving rod 611 and the second moving rod 612 to move toward each other. This, in turn, drives the two stabilizing rods 6 to move toward each other until both stabilizing rods 6 are in contact with the sidewall of the rubber sleeve. This improves the stability of the rubber sleeve as it moves on the conveyor belt 111 and reduces the possibility of the rubber sleeve being detached from the conveyor belt 111 by external force after detaching from the support rod 34.

[0049] The implementation principle of the fuel tank strap processing device in this application embodiment is as follows: First, a portion of the rubber sleeve 9 is placed on the conveyor belt 111, at which point the two spreading rods 34 are located inside the rubber sleeve 9; then, the bidirectional lead screw 361 is rotated, causing the two moving blocks 32 to move towards opposite sides, and the two moving blocks 32 cause the corresponding connecting rods 33 to rotate, and the two connecting rods 33 cause the corresponding spreading rods 34 to move towards opposite sides, so that the two spreading rods 34 spread the rubber sleeve open; then, the winding motor 23 is started, causing the winding rod 22 to rotate, so that the rubber strip wound on the winding rod 22 moves to the upper side of the rubber sleeve and is inserted into the rubber sleeve under the action of gravity; finally, the rotating motor 12 is started, causing the rotating rod 11 to rotate, thereby driving the conveyor belt 111 to rotate, effectively driving the rubber sleeve to move in the horizontal direction, so that the entire rubber strip is inserted into the entire spread rubber sleeve. The above operation does not require the staff to manually install the rubber strip and rubber sleeve, effectively improving the work efficiency of the staff.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
