Description

Technical Field

[0001] The utility model relates to the technical field of equipment for uncoiling steel coils, in particular to a steel coil uncoiling machine for a pickling production line. Background Art

[0002] The uncoiler is a special equipment for leveling metal plates. The body is a welded box-shaped structure. The variable frequency speed regulating motor drives the reel shaft after deceleration through the gear box to provide the main power for the uncoiler. The uncoiler is used to level steel plates and uneven plates. According to the relevant configuration, it can form an uncoiler, leveling, shearing production line and other plate product production lines. It is suitable for machinery, vehicles, metal products, household appliances, steel structures, decoration and other industries.

[0003] At present, the existing steel coil uncoiler for pickling production line often uses an increasing plate to increase the diameter of the uncoiler fan plate due to the different inner diameters of the steel coils, so as to achieve the effect of fixing the steel coils. However, the existing increasing plates are made of rubber, which leads to insufficient strength, and the existing increasing plates are an integral part. When the feeding end is worn after long-term use, it cannot be disassembled and replaced, and the integral increasing plate needs to be replaced, which increases the use cost and greatly reduces the practicality of the steel coil uncoiler for the pickling production line. The existing steel coil uncoiler for the pickling production line does not have a supporting buffer device, so the supporting structure needs to be moved away and supported every time the material is fed. Therefore, the impact generated when the supporting member contacts the installation shaft each time the support is supported is likely to cause damage to the inside of the installation shaft. After long-term collision, the axis center is easily offset, resulting in shaking during rotation, which greatly reduces the safety and service life of the steel coil uncoiler for the pickling production line. Summary of the invention

[0004] The main purpose of the utility model is to solve the problem that the steel coil uncoiler for the above-mentioned existing pickling production line does not have a high-strength and detachable diameter-increasing plate, so it is easy to be damaged after long-term use and the replacement cost is high. At the same time, it also does not have a buffer support device. Therefore, after long-term use, the support and the installation shaft collide easily, causing the axis to shift, causing the steel coil to rotate and shake, thereby reducing the service life and also reducing the practicality and increasing the cost of use. A steel coil uncoiler for a pickling production line is provided.

At the same time, the diameter increasing plate a and the diameter increasing plate b can be disassembled for easy replacement.

[0007] Furthermore, one end of the diameter increasing plate b away from the diameter increasing plate a is an arc-shaped surface.

[0009] Furthermore, the diameter increasing mechanism and the latch are both made of high-strength steel.

[0010] According to the above technical solution, the strength of the diameter increasing mechanism and the length of the pin are further improved by using high-strength steel material, thereby increasing its service life and the protective effect of the sector plate.

[0011] Furthermore, two of each of the second transverse reinforcing ribs, the first transverse reinforcing ribs and the latch are provided.

[0012] According to the above technical solution, the second transverse reinforcing rib, the first transverse reinforcing rib and two latches are provided, thereby improving the stability of the connection and also improving the torsion resistance.

[0014] According to the above technical solution, the downward pressure of the support member is buffered by the buffer structure, thereby reducing the collision of the support member with the installation shaft, avoiding the displacement of the internal axis of the installation shaft after long-term collision, thereby causing unstable rotation.

[0015] Furthermore, the buffer structure is provided with two, and the two guide rods are both slidably connected to the slider.

[0016] According to the above technical solution, the buffering effect and stability are improved by using two buffer structures.

[0017] Furthermore, the spring, guide rod and connecting plate are all made of high-strength steel.

DETAILED DESCRIPTION

[0032] Embodiment 1

[0033] See also Figure 1-9The present embodiment is a steel coil uncoiler for a pickling production line, which is composed of a support mechanism 1, a mounting shaft 2, a reel 3 and a fan-shaped plate 4. The support mechanism 1 is used to greatly adjust the support angle. The mounting shaft 2 is used to assist the reel 3 in rotating. The surface of the reel 3 is used to install the fan-shaped plate 4 and is connected to the transmission motor to achieve the effect of rotating the steel coil. The fan-shaped plate 4 is used to increase the diameter of the reel 3 by expanding or reducing the diameter. At the same time, a plurality of screw holes are provided on the surface for installing a diameter increasing mechanism. The diameter increasing mechanism is composed of a diameter increasing plate a6, a diameter increasing plate b7, a first transverse reinforcing rib 8, a first vertical reinforcing rib 9, a second transverse reinforcing rib 10 and a second vertical reinforcing rib 11. The diameter increasing plate a6 is used to increase the diameter of the fan-shaped plate 4, and at the same time, it is connected to the diameter increasing plate b on one side. 7 is connected, the diameter-increasing plate b7 is used to increase the diameter of the sector plate 4 and is one end of the steel coil feeding, the first transverse reinforcing rib 8 and the first vertical reinforcing rib 9 are fixed to the inner side of the diameter-increasing plate a6 to improve the strength and torsion resistance of the diameter-increasing plate a6, the first transverse reinforcing rib 8 is hollowed out, the second transverse reinforcing rib 10 and the second vertical reinforcing rib 11 are fixed to the inner side of the diameter-increasing plate b7 to improve the strength and torsion resistance of the diameter-increasing plate b7, a pin 12 is fixed to the right end of the second transverse reinforcing rib 10, the diameter of the pin 12 matches the hollow hole in the first transverse reinforcing rib 8, the pin 12 can be inserted into the hole of the first transverse reinforcing rib 8 for connection, thereby achieving the effect that the diameter-increasing plate a6 and the diameter-increasing plate b7 are detachable.

[0034] Furthermore, the left end of the diameter increasing plate b7, that is, the end away from the diameter increasing plate a6, is an arc-shaped surface, which is convenient for reducing the friction when the steel coil is fed and improving the smoothness of the feeding.

[0035] Furthermore, the diameter increasing mechanism and the latch pin 12 are both made of high-strength steel, which increases their strength and thus increases the service life of the diameter increasing plates a6 and b7.

[0036] Furthermore, two second transverse reinforcing ribs 10, two first transverse reinforcing ribs 8 and two latches 12 are provided, thereby improving their strength and also improving the connection stability between the diameter-increasing plate a6 and the diameter-increasing plate b7.

[0037] The working principle of this embodiment is as follows: during installation, first fix the diameter increasing plate a6 on the fan-shaped plate 4 by bolts, then connect the pin 12 with the cavity in the first transverse reinforcing rib 8, and finally fix the diameter increasing plate b7 by bolts to complete the installation. When loading, loading is carried out through the arc surface at one end of the diameter increasing plate b7. When the reel 3 rotates, the first transverse reinforcing rib 8, the first vertical reinforcing rib 9, the second transverse reinforcing rib 10 and the second vertical reinforcing rib 11 can increase the strength of the diameter increasing plate a6 and the diameter increasing plate b7, and avoid the situation where the diameter increasing plate a6 and the diameter increasing plate b7 are broken due to the strong rotational torque of the steel coil. When the feeding end of the diameter increasing plate b7 is damaged after long-term use, the bolts can be removed and the pin 12 can be pulled out at the same time, and the diameter increasing plate b7 can be replaced alone, which further improves the practicality of the steel coil uncoiler for the pickling production line, reduces its use cost, and avoids the need to replace the entire diameter increasing mechanism after damage.

[0038] Embodiment 2

[0039] The structure of this embodiment is basically the same as that of the first embodiment, and the following features are added on the basis of the first embodiment: there is a mounting groove 13 on the inner top of the movable arm 5, and a buffer structure is installed inside the mounting groove 13. The buffer structure is used to reduce the downward pressure of the support member 21. The buffer structure is composed of a guide rod 14 and a spring 15. The guide rod 14 is laterally fixed inside the mounting groove 13. The guide rod 14 is provided with a spring 15 and a slider 16. The slider 16 is slidably connected to the guide rod 14 and can move horizontally on its surface. The spring 15 is located on the left side of the slider 16 to facilitate buffering the downward pressure of the support member 21. The slider 16 is rotatably connected to a connecting plate 17, and the connecting plate 17 can be rotated by a rotating shaft or punching. The connecting plate 17 is far A connecting piece 18 is rotatably connected to one end of the slider 16, and can also be rotatably connected by a rotating shaft or punching, etc. A base 19 is fixed on the top of the connecting piece 18, and the connecting piece 18 is used for the connection between the base 19 and the connecting plate 17. The connecting piece 18 is misaligned with the slider 16, and an angle is maintained between the connecting piece 18 and the connecting plate 17, so that the slider 16 can be pushed to one side through the connecting plate 17 when the base 19 is pressed down. A movable shaft 20 is fixed to the left side above the mounting groove 13, and the movable shaft 20 is rotatably connected to the base 19. The base 19 rotates up and down with the movable shaft 20 as the base point. A support piece 21 is fixed on the top of the base 19, and the support piece 21 is used to contact the mounting shaft 2, so that the movable arm 5 can support it.

[0040] Furthermore, two buffer structures are provided, and both guide rods 14 are movably connected to the slider 16, thereby improving the buffer effect and stability.

[0041] Furthermore, the spring 15, the guide rod 14 and the connecting plate 17 are all made of high-strength steel, which improves the stability and durability of the buffer structure.

[0042] Furthermore, the movable arm 5 is in a concave shape, which facilitates the rotation of the base 19 and saves materials.

[0043] The working principle of this embodiment is as follows: after the steel coil is installed, the support mechanism 1 is controlled to support the installation shaft 2. When the support member 21 contacts the installation shaft 2, the pressure generated by the installation shaft 2 and the support member 21 is transmitted through the base 19. When the base 19 is subjected to pressure, it rotates downward through the movable shaft 20. When the base 19 rotates downward, the pressure is transmitted to the connecting plate 17 through the connecting member 18. At this time, the connecting plate 17 transmits its downward pressure to the slider 16. At this time, the slider 16 is pushed by the connecting plate 17 to move on the slide rod 16. When the slider 16 moves to one side, it pushes the spring 15 on one side, and the spring 15 buffers its downward pressure, thereby avoiding the impact force generated when the support member 21 supports the installation shaft 2, avoiding the impact force causing the axis center inside the installation shaft 2 to shift, causing shaking during rotation, and greatly improving the service life of the steel coil uncoiler for the pickling production line.
