Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe processing, and specifically relates to a steel strip conveying and supporting device. Background Technique

[0002] The stainless steel pipe is processed from a stainless steel thin plate. The width of the stainless steel thin plate is relatively large. Before producing the stainless steel pipe, the wide stainless steel thin plate is cut into narrow stainless steel strips by a slitting machine and then wound up separately for standby. The stainless steel strip is unwound by an unwinding roller and conveyed to the stainless steel pipe processing production line. Since the stainless steel strip coil needs to be loaded regularly and the overall diameter is relatively large, generally an unwinding mechanism is arranged at a position with a certain distance reserved at the front end of the stainless steel pipe processing production line, which not only facilitates the disassembly and assembly of the stainless steel strip unwinding roller, but also ensures that there is a surplus of the unwound steel strip to meet the requirements of the stainless steel pipe processing production line with variable speed.

[0003] In the prior art, most enterprises directly suspend the steel strip during unwinding. However, when the surplus of the unwound steel strip increases, the unwound steel strip is likely to contact the ground below, resulting in scratches and dust adhesion on the surface of the unwound steel strip, increasing the workload of polishing and dust removal during the production process and being unfavorable for efficient production. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides a steel strip conveying and supporting device, which is used to solve the problem that there is no supporting measure during the unwinding of the stainless steel strip, and it is easy to contact the ground when the surplus of the unwound steel strip increases, resulting in scratches and dust adhesion on the surface.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A steel strip conveying and supporting device includes a fixed base, on which a water tank and two piston cylinders vertically arranged on both sides of the water tank are fixedly installed. The water tank is filled with water and is communicated with the piston cylinders. A piston rod is movably inserted into the piston cylinder, and the lower end of the piston rod is fixedly connected to a piston disc that is slidably connected to the inner side wall of the piston cylinder. The top ends of the two piston rods both extend above the piston cylinder and are fixedly connected to support frames located on both sides of the unwound steel strip. Between the two support frames, a limiting roller and a supporting roller located above and below the unwound steel strip are installed respectively.

[0007] Preferably, communication pipes are arranged at positions near the bottom on both sides of the water tank, and the water tank is communicated with the piston cylinders through the communication pipes.

[0008] Preferably, the lower end of the piston cylinder is connected to the fixed base through a strengthening fixing seat, and a fixing hoop fixedly connected to the side surface of the water tank is installed on the upper end surface of the piston cylinder.

[0009] Preferably, a linear bearing seat which is fixedly connected to the top end of the piston cylinder and sleeved on the surface of the piston rod is provided.

[0010] Preferably, a reinforcing gusset plate is fixedly connected between the piston rod and the support frame.

[0011] Preferably, there are two support rollers, and the limiting roller is located above the position between the two support rollers.

[0012] Preferably, a round cover is installed on the water injection port at the top of the water tank, and air holes are arranged on the side surface of the round cover above the water injection port.

[0013] Preferably, a plurality of horizontally unclosed grid plates are equidistantly arranged in the vertical direction inside the water tank.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, the unwound steel strip is limited and supported by the limiting roller and the support roller installed on the support frame, so as to prevent the unwound steel strip from contacting the ground. The lower part of the support frame is movably supported by the piston rod, and the piston rod provides the support force through the reverse acting force of the gravity of the water in the water tank and the piston cylinder. When the surplus of the unwound steel strip increases, it can press the support roller to move downward to make way. When the surplus of the unwound steel strip decreases, it can pull the limiting roller to move upward for replacement, adapting to the change of the speed of the stainless steel pipe processing production line, without energy consumption and additional power, with simple structure and convenient use, and solving the problem that there is no support measure during the unwinding of the stainless steel strip, and it is easy to contact the ground surface, resulting in scratches and dust adhesion when the surplus of the steel strip increases.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, the present utility model provides a technical solution: a steel belt conveying and supporting device, including a fixed base 1, a water tank 2 fixedly installed on the fixed base 1, and two piston cylinders 3 vertically arranged on both sides of the water tank 2. A round cover 16 is installed on the water injection port 15 at the top of the water tank 2. An air hole 17 is provided on the side surface of the round cover 16 above the water injection port 15. A plurality of horizontally unclosed grid plates 18 are equidistantly arranged in the water tank 2 along the vertical direction.

[0024] The water tank 2 is filled with water and is communicated with the piston cylinder 3. Communication pipes 10 are provided at positions near the bottom on both sides of the water tank 2. The water tank 2 is communicated with the piston cylinder 3 through the communication pipes 10. The lower end of the piston cylinder 3 is connected to the fixed base 1 through a strengthened fixing seat 11. A fixed hoop 12 fixedly connected to the side surface of the water tank 2 is installed on the upper end surface of the piston cylinder 3. A piston rod 4 is movably inserted into the piston cylinder 3. A linear bearing seat 13 slidably sleeved on the surface of the piston rod 4 is fixedly connected to the top end of the piston cylinder 3. The lower end of the piston rod 4 is fixedly connected to a piston disc 5 slidably connected to the inner side wall of the piston cylinder 3.

[0025] The top ends of the two piston rods 4 both extend above the piston cylinder 3 and are fixedly connected to support frames 7 located on both sides of the unreeled steel belt 6. A strengthened angle plate 14 is fixedly connected between the piston rod 4 and the support frame 7. A limiting roller 8 and a support roller 9 respectively located above and below the unreeled steel belt 6 are installed between the two support frames 7. There are two support rollers 9, and the limiting roller 8 is located above the position between the two support rollers 9.

[0026] Working principle:

[0027] The limiting roller 8 and the supporting roller 9 limit and support the uncoiling steel strip 6 to prevent the uncoiling steel strip 6 from contacting the ground. The lower part of the support frame 7 is movably supported by the piston rod 4. The piston rod 4 provides the supporting force through the reverse acting force of the gravity of the water in the water tank 2 and the piston cylinder 3. When the surplus of the uncoiling steel strip 6 increases, it can press the supporting roller 9 to move downward to make way. The piston disc 5 pushes the water in the piston cylinder 3 to flow into the water tank 2, and the excess air in the water tank 2 is discharged from the air hole 17. When the surplus of the uncoiling steel strip 6 decreases, it can pull the limiting roller 8 to move upward for replacement, pulling the piston disc 5 to move upward. The water surface in the water tank 2 is under atmospheric pressure, pushing the water in the water tank 2 to flow into the piston cylinder 3, and the air pressure in the water tank 2 drops, and air enters through the air hole 17 for compensation, adapting to the change of the speed of the stainless steel pipe processing production line, without energy consumption and without additional power, with simple structure and convenient use.
