Description

Technical Field

[0001] The present invention relates to a buffer device, in particular to a buffer device used in a strip steel conveying system. Background Art

[0002] Continuous strip production lines typically feature two unwinding systems, each with two corresponding strip channels. These channels converge in front of a welder, where the ends of the two strips are welded together, enabling continuous operation. The two channels are arranged one above the other, each equipped with a shear to remove defects such as poorly shaped sections at the ends of the strip.

[0003] Since the cross-cutting position of the upper channel is relatively high, the head and tail steel plates after shearing have a high speed when falling onto the steel plate conveyor belt, which generates a high impact force. This often causes the steel plate conveyor belt to be damaged, abnormal or even broken, resulting in unit shutdown and affecting normal production.

[0004] In addition, the corners of steel plates are often inserted between the protective strip linings on the surface of the conveyor belt during the high-speed falling process (the conveyor belt is made of rubber and will be stretched over time, while the size of the lining remains unchanged), causing the corners of the steel plates to be stuck between the linings. When the steel plates are brought to the highest point, they cannot fall smoothly into the waste hopper. Instead, they follow the conveyor belt to the bottom of the conveyor belt and fall when the conveyor belt reaches the lowest point and turns again, causing a large number of steel plates to accumulate at the lowest point, which can easily cause the conveyor belt to be stuck and broken. In addition, cleaning the steel plates requires a lot of manpower, and there is a risk of cuts and other risks in carrying the steel plates, which seriously affects on-site production. Summary of the Invention

[0005] The purpose of the present invention is to provide a steel plate falling buffer device, which can reduce the impact force of the steel plate on the conveyor belt, improve the service life of the conveyor belt, and at the same time prevent the corners of the steel plate from being stuck between the protective strip linings, and prevent the steel plate from being carried under the conveyor belt by the linings to cause steel plate accumulation.

[0011] Furthermore, the steel plate blanking buffer device described in the present invention also includes: a first limit block and a second limit block, which are arranged on the balance plate and respectively arranged on both sides of the first rotation axis; the first limit block and the second limit block respectively limit the rotation angle of the balance plate in the first rotation direction and the second rotation direction.

[0030] The steel plate blanking buffer device of the present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments of the specification. However, such explanation and illustration do not constitute an undue limitation to the technical solution of the present invention.

[0031] During the steel plate production process, due to the heavy weight of the steel plates, the falling steel plates will cause a large impact on the conveyor belt, which can easily cause the conveyor belt to jam and break, shortening the conveyor belt's life. Furthermore, during the steel plate production process, the steel plates may get stuck between the protective liner strips during the blanking process, causing the steel plates to be carried under the conveyor belt and accumulate.

[0032] Based on this, the present invention provides a material drop buffering device in one embodiment.

[0033] Figure 1 A schematic diagram of the overall structure of the steel plate blanking buffer device described in the present invention in one embodiment is shown.

[0034] like Figure 1As shown, in this embodiment, the steel plate falling buffer device includes: a chute 1; a balance plate 2, which is rotatably arranged below the outlet of the chute 1 through a first rotating shaft 4, and the balance plate 2 can rotate around the first rotating shaft 4 in a first rotating direction and a second rotating direction opposite to the first rotating direction. The balance plate 2 has a bearing end (i.e., Figure 1 The right end of the figure); the counterweight element 10 is provided on the balance plate 2 through the counterweight bolt 11, and is located on both sides of the first rotating shaft 4 with the load-bearing end; the swing plate 3 is rotatably provided on the swing plate bracket 13 through the second rotating shaft 5, so as to be provided in the path of the steel plate blanking, in front of the chute 1.

[0035] In some specific embodiments, such as Figure 1 As shown, the chute 1 can be arranged at an angle so that the steel plate 14 can fall smoothly. After the steel plate 14 falls on the chute 1, it slides down the inclined surface of the chute 1 under the action of gravity until it reaches the balance plate 2.

[0036] In some more specific embodiments, Figure 1 As shown, the steel plate blanking buffer device may further include a chute bracket 12, the chute 1 may be fixed on the chute bracket 8, and the chute bracket 8 may be fixed on the foundation.

[0037] Figure 2 Shows Figure 1 A partial enlarged view of point D in the middle.

[0038] like Figure 2 As shown, the steel plate blanking buffer device may further include: a first limit stopper 17 and a second limit stopper 18, both of which are provided on the balancing plate 2 and are respectively provided on both sides of the first rotation axis 4. Thus, the first limit stopper 17 and the second limit stopper 18 can respectively limit the rotation angle of the balancing plate 2 in the first rotation direction and the second rotation direction.

[0039] In some specific embodiments, such as Figure 2 As shown, the balancing plate 2 is arranged on the balancing plate bracket 19 via the first rotating shaft 4 , and the balancing plate bracket 19 is fixedly arranged on the chute 1 .

[0040] Figure 3 Shows Figure 1 View from center AA.

[0041] In some more specific embodiments, Figure 2 As shown, the first rotation axis may be configured to include a first trunnion 401 and a first cotter pin 402 , which connects the balance board to the balance board bracket 19 so that the balance board 2 can rotate.

[0042] Figure 4Shows Figure 1 View from CC.

[0043] In some specific embodiments, such as Figure 4 As shown, the balance plate 2 is provided with a waist-shaped hole 101 extending along the length direction of the balance plate 2. The weight element 10 is connected to the balance plate 2 by an adjusting bolt inserted into the waist-shaped hole 101 to adjust the position of the weight element 10 relative to the balance plate 2 (for example, Figure 1 The position in the left and right directions) can be used to adjust the pressure required for the balance plate 2 to start rotating. At the same time, the balance plate 2 can absorb part of the kinetic energy generated by the falling of the steel plate.

[0044] Figure 5 Shows Figure 1 View from the middle BB.

[0045] In some specific embodiments, such as Figure 5 As shown, the second rotation axis may be configured to include a second ear shaft 501 and a second cotter pin 502 to set the swing plate 3 on the swing plate bracket 13 , so that the swing plate 3 can be rotated.

[0046] Figure 6 The structure of the conveying device of the steel plate blanking buffer device according to one embodiment of the present invention is shown in a partially enlarged manner.

[0047] like Figure 1 and Figure 6 As shown, the steel plate falling buffer device may further include a conveying device provided below the chute 1. In some more specific embodiments, the conveying device may include a conveying belt 15, wherein the conveying belt 15 is provided with a protective lining 16.

[0048] In this way, after the steel plate 14 falls onto the chute 1 , it slides down the inclined surface of the chute 1 under the action of gravity until it reaches the balance plate 2 .

[0049] When the steel plate 14 falls and hits the balance plate 2, the balance plate 2 will rotate slightly to absorb part of the kinetic energy of the steel plate 14. The steel plate 14 continues to move until it hits the swing plate 3. At this time, the kinetic energy of the steel plate 14 is basically all transferred to the swing plate 3. Since the mass of the swing plate 3 is much greater than that of the steel plate 14, the swing plate 3 will only swing slightly.

[0050] When the subsequent steel plate 14 falls and hits the preceding one, it continues to move until it hits the swing plate 3. The kinetic energy of the steel plate 14 is transferred to the swing plate 3, causing it to swing slightly. Simultaneously, the balance plate 2 begins to rotate under the weight of the steel plates. When the edge of the steel plate in contact with the swing plate 3 is lower than the bottom of the swing plate 3, the steel plate slowly slides onto the protective strip liner 16 on the surface of the conveyor belt 15. This greatly reduces the impact of the steel plate on the transport device and prevents it from getting stuck in the gaps between the liner plates.
