DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts that are not described and disclosed in detail in the following embodiments of the present invention should be understood as the existing technologies known or should be known to those skilled in the art, such as the working principle that the limit plate 4 can be driven to move toward or away from the forward and reverse screw rods 5 during rotation, the transmission connection between the chain 12 and the sprocket 11, and the structure and principle of the tensioning wheel 13.

[0028] Example 1

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a steel strip flattening machine suitable for steel strips of various widths includes a frame 1, an extrusion roller 2, a limit plate 4, a forward and reverse screw rod 5, a support column 6, a driving component and an anti-slip component. The driving component can drive the forward and reverse screw rod 5 to rotate. During the rotation of the forward and reverse screw rod 5, the limit plate 4 is driven to move toward or away from the forward and reverse screw rod 5, so as to adjust the distance between the two limit plates 4. It is suitable for steel strips of different widths, has low cost and is easy to operate. The anti-slip component can prevent the steel strip roll 3 from falling off, so as to ensure work efficiency and avoid damage to the steel strip flattening machine and staff.

[0030] The steel strip flattening machine includes a flattening mechanism, a coil feeding mechanism and a frame 1. The flattening mechanism includes a plurality of squeezing rollers 2 rotatably connected to the frame 1. The plurality of squeezing rollers 2 rotate to flatten the steel strip of the steel strip coil 3 to facilitate subsequent operations on the steel strip.

[0031] The roll feeding mechanism includes:

[0032] Two limiting plates 4 for limiting the position of the steel strip coil 3;

[0033] A plurality of forward and reverse screw rods 5 are rotatably arranged on the frame 1, and all the forward and reverse screw rods 5 pass through two limit plates 4. During the rotation of the forward and reverse screw rods 5, the two limit plates 4 are driven to move toward or away from each other along the forward and reverse screw rods 5;

[0034] A plurality of support columns 6 rotatably disposed on the frame 1 for supporting the steel strip coil 3;

[0035] A driving assembly disposed on the frame 1 and used for driving the forward and reverse screw rods 5 to rotate;

[0036] The anti-dropping assembly arranged on the two limiting plates 4 is used to prevent the steel strip coil 3 from falling off.

[0037] During the high-speed rotation of the steel strip coil 3, the thickness of the steel strip coil 3 becomes thinner, and the steel strip coil 3 is easy to fall off, which will cause damage to the steel strip flattening machine and the staff. Figure 3 As shown, the anti-slip assembly includes first anti-slip plates 7 respectively connected to the outer side walls of the two limit plates 4, and a plurality of anti-slip columns 8 that can pass through the two first anti-slip plates 7. The anti-slip columns 8 cooperate with the limit plates 4 to limit the position of the steel strip coil 3. First, the steel strip coil 3 is placed between the two limit plates 4, and finally the anti-slip columns 8 are passed through the two first anti-slip plates 7. The frame 1, the two limit plates 4, the two first anti-slip plates 7 and the anti-slip columns 8 cooperate with each other to prevent the steel strip coil 3 from falling off.

[0038] When one steel strip roll 3 is flattened, if the width of the next steel strip roll 3 is the same as the previous one, there is no need to adjust the distance between the two limiting plates 4. The anti-slip column 8 is removed from the first anti-slip plate 7, and the steel strip roll 3 is placed between the two limiting plates 4. Finally, the anti-slip column 8 is passed through the two first anti-slip plates 7.

[0039] When one steel strip roll 3 is flattened, if the width of the next steel strip roll 3 is different from that of the previous steel strip roll 3, first remove the anti-slip column 8 from the first anti-slip plate 7, then adjust the distance between the two limiting plates 4, then place the steel strip roll 3 between the two limiting plates 4, and finally pass the anti-slip column 8 through the two first anti-slip plates 7.

[0040] All the forward and reverse screw rods 5 are connected by a transmission assembly, which includes a plurality of sprockets 11 correspondingly arranged on the forward and reverse screw rods 5, and all the sprockets 11 are meshed and connected with a chain 12. When one of the forward and reverse screw rods 5 rotates, the other forward and reverse screw rods 5 can be driven to rotate, and when all the forward and reverse screw rods 5 rotate, the limit plates 4 are driven to move toward or away from each other along the forward and reverse screw rods 5, so as to adjust the distance between the two limit plates 4.

[0041] Since the chain 12 is long, the deadweight of the chain 12 may cause the chain 12 to sag or detach from the sprocket 11, which may affect the transmission efficiency and reliability. The inner wall of the frame 1 is provided with a tensioning wheel 13 meshing with the chain 12, and the tensioning wheel 13 is used to tension the chain 12. The tensioning wheel 13 can tension the chain 12 to ensure the normal transmission of the chain 12 and the sprocket 11, and avoid the chain 12 detaching from the sprocket 11 due to the chain 12 and the sprocket 11 becoming loose after working for a period of time.

[0042] The driving assembly includes a driving motor, and the output shaft of the driving motor is coaxially fixedly connected to one of the forward and reverse screw rods 5. The driving motor drives the forward and reverse screw rods 5 connected to the driving motor to rotate, and the forward and reverse screw rods 5 drive other forward and reverse screw rods 5 to rotate through the sprocket 11 and the chain 12. During the rotation of all the forward and reverse screw rods 5, the limit plates 4 are driven to move toward or away from each other along the forward and reverse screw rods 5, so as to adjust the distance between the two limit plates 4.

[0043] The driving assembly includes a hand wheel 14, which is coaxially fixedly connected to one of the forward and reverse screw rods 5. The hand wheel 14 is rotated clockwise or counterclockwise to drive the forward and reverse screw rods 5 connected to the hand wheel 14 to rotate, and the forward and reverse screw rods 5 drive other forward and reverse screw rods 5 to rotate through the sprocket 11 and the chain 12. During the rotation of all the forward and reverse screw rods 5, the limit plates 4 are driven to move toward or away from each other along the forward and reverse screw rods 5, so as to adjust the distance between the two limit plates 4.

[0044] The flattening mechanism also includes a positioning rod 15 fixedly arranged on the frame 1, and a limiting rod 16 is arranged above the positioning rod 15. The limiting rod 16 cooperates with the positioning rod 15 to ensure that the steel strip roll 3 fits the positioning rod 15. The steel strip of the steel strip roll 3 passes through the gap between the limiting rod 16 and the positioning rod 15 and enters between the squeezing rollers 2 for flattening.

[0045] The steel strip coil 3 includes two types, one with a steel strip shaft and one without a steel strip shaft. The limit plate 4 is provided with a groove 17 for supporting the steel strip shaft of the steel strip coil 3. When the steel strip coil 3 is provided with a steel strip shaft, the steel strip shaft is placed in the groove 17, and the groove 17 plays a role in supporting the steel strip shaft.

[0046] The bottom of the frame 1 is provided with a driving wheel 18 for driving the frame 1 to move. In the present embodiment, the bottom of the frame 1 is provided with four driving wheels 18, when the frame 1 position needs to be moved, the frame 1 is pushed, and the four driving wheels 18 enable the frame 1 to move steadily on the ground.

[0047] The above is a basic implementation method of the utility model, which can be further improved, optimized and limited on the basis of the above to obtain the following embodiments:

[0048] Example 2

[0050] like Figure 4 As shown, the anti-slip assembly includes a second anti-slip plate 9 connected to the outer side wall of a limiting plate 4, and an anti-slip cover 10 is hinged on the top of the second anti-slip plate 9. The anti-slip cover 10 cooperates with the limiting plate 4 to limit the position of the steel strip coil 3. First, the anti-slip cover 10 is opened, and then the steel strip coil 3 is placed between the two limiting plates 4, and finally the anti-slip cover 10 is covered above the steel strip coil 3. The frame 1, the two limiting plates 4, the second anti-slip plate 9 and the anti-slip cover 10 cooperate with each other to prevent the steel strip coil 3 from falling off.

[0051] When one steel strip roll 3 is flattened, if the width of the next steel strip roll 3 is the same as that of the previous steel strip roll 3, there is no need to adjust the distance between the two limiting plates 4. The anti-slip cover 10 is opened, and the steel strip roll 3 is placed between the two limiting plates 4, and finally the anti-slip cover 10 is covered on top of the steel strip roll 3.

[0052] When one steel strip roll 3 is flattened, if the width of the next steel strip roll 3 to be loaded is different from that of the previous steel strip roll 3, first open the anti-slip cover 10, then adjust the distance between the two limit plates 4, then put the steel strip roll 3 between the two limit plates 4, and finally cover the anti-slip cover 10 on top of the steel strip roll 3.
