Description

Technical Field

[0001] This application relates to the field of button sewing machines, and in particular to a centering device for sewing button centers. Background Technology

[0002] Belt fastener machines are key pieces of equipment in industrial production used to connect the two ends of conveyor belts, and are widely used in mining, logistics, and manufacturing industries. By precisely fastening metal fasteners into both ends of the belt, a closed loop structure is formed, ensuring the belt's proper functioning on the conveyor. However, in practice, precise alignment of the belt with the fastener machine is crucial for ensuring the quality of the fastening.

[0003] Currently, when fastening belt buckles, the belt position needs to be manually adjusted to ensure it is perpendicular to the belt fastening machine before the machine is used for fastening, preventing deviations during the fastening process. If the belt is not perpendicular to the machine, the angle and spacing of the fasteners will be off, resulting in uneven fastening distribution. This not only affects the strength of the belt connection but may also cause uneven stress on the belt during operation, accelerating belt wear.

[0004] However, manually adjusting the belt requires operators to spend a lot of time and effort. Each adjustment requires repeated observation and adjustment of the belt's position, which is a rather tedious process. This can significantly reduce work efficiency, especially when the belt needs to be adjusted frequently or when dealing with a large number of belts. Utility Model Content

[0005] To address the cumbersome process of manually adjusting belts, which requires repeated checks and repositioning, and the significant decrease in efficiency when frequently adjusting or handling large batches of belts, this application provides a centering device for fastening belts.

[0006] The centering device for fastening a button center provided in this application adopts the following technical solution: A centering device for fastening a buckle includes a frame, a left-hand wheel, and a right-hand wheel. Support frames are symmetrically fixed on both sides of the frame. A limiting plate slides inside the supporting frame. The two limiting plates are fixedly connected by a connecting block. The left-hand wheel and the right-hand wheel are located at opposite ends of the connecting block on the same side. A left vertical plate is threaded onto the left-hand wheel, and a right vertical plate is threaded onto the right-hand wheel. The thread direction on the left vertical plate is opposite to the thread direction on the right vertical plate. A connecting rod is provided between the left-hand wheel and the right-hand wheel.

[0007] By adopting the above technical solution, the left and right rotating wheels are located at both ends of the connecting block, and are respectively threaded with a left vertical plate and a right vertical plate. The thread direction on the left vertical plate is opposite to that on the right vertical plate, so that rotating the left and right rotating wheels in the same direction can drive the left and right vertical plates to move synchronously in centering or out of center. The connecting rod between the left and right rotating wheels is fixed with bolts, which not only facilitates disassembly and assembly but also ensures the synchronicity of the left and right rotating wheels during operation, further improving the centering accuracy.

[0008] Optionally, both the left and right upright plates are provided with limiting grooves, and both the left and right upright plates are embedded in the connecting block through the limiting grooves.

[0009] By adopting the above technical solution, the setting of the limiting groove enables the left and right upright plates to be stably fitted onto the connecting block, thereby ensuring the precise guidance of the left and right upright plates when moving along the connecting block, and ensuring that the angle and spacing of the belt binding are more uniform.

[0010] Optionally, both ends of the connecting block are fixed with mounting plates, and the two mounting plates are fixed by limiting rods. The left and right upright plates are both sleeved on the limiting rods.

[0011] By adopting the above technical solution, the cooperation between the mounting plates fixed at both ends of the connecting block and the limiting rods can guide the movement of the left and right vertical plates, ensuring their stable sliding along the predetermined direction. Simultaneously, the limiting rods prevent the left and right vertical plates from shifting or falling off during adjustment, thereby ensuring the accuracy and reliability of the belt alignment process.

[0012] Optionally, a cylinder is fixed on the limiting plate, and the cylinder is located below the receiving frame.

[0013] By adopting the above technical solution, the cylinder can provide stable lifting power for the limit plate. The height of the limit plate can be precisely adjusted by the cylinder to better accommodate belts of different thicknesses, ensuring belt stability during alignment.

[0014] Optionally, a fixing block is provided above the connecting block, and both ends of the fixing block are fixed to the receiving frame.

[0015] The cylinder drives the limit plate to move upward, causing the connecting block to contact the belt. The belt is sandwiched between the connecting block and the fixing block. The connecting block can bear the weight of the belt, facilitating subsequent alignment and adjustment of the belt.

[0016] Optionally, one end of the connecting block is fixed with a first stop block that restricts the movement of the left upright plate, and the other end of the connecting block is fixed with a second stop block that restricts the movement of the right upright plate.

[0017] By adopting the above technical solution, the first stop and the second stop are fixed at both ends of the connecting block, which can effectively limit the movement range of the left and right upright plates and prevent the left and right upright plates from being displaced excessively during the adjustment process, thus causing structural instability.

[0018] Optionally, the frame is also equipped with a button-attaching machine, which is located behind the fixing rod.

[0019] By adopting the above technical solution, the fastening machine is mounted on the frame and located behind the fixing rod, forming an integrated structure with the centering device. This allows the belt to be fastened directly on the same machine after centering adjustment, without the need to transfer the belt to other equipment. This not only improves work efficiency but also ensures that the belt position after centering will not shift due to transfer.

[0020] In summary, this application includes at least one of the following beneficial technical effects: By symmetrically setting the left and right rotating wheels on the same side and having threads opposite to those of the left and right vertical plates, the left and right rotating wheels rotating in the same direction can flexibly adjust the distance between the left and right vertical plates, achieving precise alignment of the belt and effectively avoiding angle and spacing deviations caused by inaccurate alignment during the fastening process.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a centering device for fastening a button center.

[0026] Reference Figure 1 A centering device for attaching buttons includes a frame 1, a left upright plate 7 and a right upright plate 8. Supporting frames 4 are fixed on both sides of the frame 1. The two supporting frames 4 are connected by a fixing block 14. A button attaching machine 17 is also provided behind the fixing block 14 and is fixed on the frame 1. The button attaching machine 17 and the fixing block 14 are on the same horizontal line.

[0027] Reference Figure 2 A limiting plate 5 slides inside the receiving frame 4, and a cylinder 13 is fixed below the limiting plate 5. Activating the cylinder 13 can push the limiting plate 5 to move on the receiving frame 4.

[0028] Reference Figure 3 Both the left upright plate 7 and the right upright plate 8 have limiting grooves 10, which allow the left upright plate 7 and the right upright plate 8 to be embedded in the connecting block 6 through the limiting grooves 10. The limiting grooves 10 also provide guidance for the left upright plate 7 and the right upright plate 8, allowing the left upright plate 7 and the right upright plate 8 to move along the connecting block 6 under the action of the limiting grooves 10.

[0029] Reference Figure 4 The two limiting plates 5 are fixed together by a connecting block 6, and the left upright plate 7 and the right upright plate 8 are located on the same side of the connecting block 6. A left-hand rotating wheel 2 is threaded onto the left upright plate 7, and a right-hand rotating wheel 3 is threaded onto the right upright plate 8. In addition, the left-hand rotating wheel 2 and the right-hand rotating wheel 3 are only threaded in the middle section, so the movement distance of the left upright plate 7 and the right upright plate 8 is limited.

[0030] A connecting rod 9 is provided between the left-hand rotating wheel 2 and the right-hand rotating wheel 3. The two ends of the connecting rod 9 are fixed to the left-hand rotating wheel 2 and the right-hand rotating wheel 3 respectively by bolts. Fixing the left-hand rotating wheel 2 and the right-hand rotating wheel 3 to the two ends of the connecting rod 9 by bolts facilitates disassembly and assembly.

[0031] Reference Figure 4The threads on the left-hand wheel 2 and the right-hand wheel 3 are in opposite directions. When the left-hand wheel 2 and the right-hand wheel 3 are rotated clockwise in the same direction, the left vertical plate 7 and the right vertical plate 8 move in the same direction along the connecting block 6 to center, reducing the distance between the left vertical plate 7 and the right vertical plate 8 and clamping the belt. When the left-hand wheel 2 and the right-hand wheel 3 are rotated counterclockwise in the same direction, the left vertical plate 7 and the right vertical plate 8 move in opposite directions along the connecting block 6 to de-center, increasing the distance between the left vertical plate 7 and the right vertical plate 8 and releasing the clamping of the belt.

[0032] Reference Figure 5 Two mounting plates 11 are also installed on the connecting block 6. The two mounting plates 11 are fixed together by a limiting rod 12. The left vertical plate 7 and the right vertical plate 8 are coaxially sleeved on the limiting rod 12. When the left rotating wheel 2 and the right rotating wheel 3 are rotated, the limiting rod 12 guides the movement of the left vertical plate 7 and the right vertical plate 8, preventing the left vertical plate 7 and the right vertical plate 8 from shifting or falling off during the adjustment process, thereby ensuring the accuracy and reliability of the belt alignment process.

[0033] Reference Figure 5 A first stop 15 is fixed on one end of the connecting block 6 to restrict the movement of the left vertical plate 7, and a second stop 16 is fixed on the other end of the connecting block 6 to restrict the movement of the right vertical plate 8. The first stop 15 and the second stop 16 are arranged between the left vertical plate 7 and the right vertical plate 8 to further restrict the movement range of the left vertical plate 7 and the right vertical plate 8, and to prevent the left vertical plate 7 and the right vertical plate 8 from moving excessively and causing wear and damage to the belt.

[0034] The implementation principle of the centering device for fastening a belt according to an embodiment of this application is as follows: When the belt to be fastened deviates from its position and is not perpendicular to the fastening machine 17, the starting cylinder 13 pushes the limiting plate 5 to move the connecting block 6 upward to contact the belt. Then, the left rotating wheel 2 and the right rotating wheel 3 rotate clockwise in the same direction, driving the left upright plate 7 and the right upright plate 8 to move in the same direction along the connecting block 6 to achieve centering and clamping of the belt, thereby making the belt perpendicular to the fastening machine 17. After the belt position is adjusted, since the fastening machine 17 and the fixing block 14 are on the same horizontal line and fixed on the frame 1, the belt can be fastened directly, ensuring uniform fastening.
