Description

Technical Field

[0001] The utility model relates to the technical field of steel coil processing equipment, in particular to a support head of an uncoiler with a guide sleeve. Background Art

[0002] The uncoiler is a special equipment for leveling metal plates. It 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. The uncoiler is one of the important and indispensable equipment in the welded pipe production line. One of its functions is to support the steel coil by tightening the inner hole of the steel coil; the other is to feed the head of the steel strip into the leveling machine by rotating with the cooperation of the straightening machine, and the uncoiler support head is used to assist the reel to rotate and support it. At the same time, the steel coil is also loaded from the support cylinder when loading.

[0003] At present, the existing uncoiler support head does not have a guide sleeve. Therefore, when loading, the bending part of the inner ring jaws of the steel coil will be stuck with the fan-shaped plate or the reel, thereby reducing the production efficiency. At the same time, the bending part of the inner ring jaws of the steel coil will directly collide with the reel and the fan-shaped plate, which can easily cause the reel to wear or even the fan-shaped plate to break, greatly reducing the practicality of the uncoiler support head, thereby reducing the service life of the uncoiler. Summary of the invention

[0004] The main purpose of the utility model is to solve the problem that the above-mentioned existing uncoiler support head does not have a guide structure, which causes the bending part of the inner ring jaws of the steel coil to be stuck with the reel during use, and even directly hits the reel and the fan-shaped plate, causing damage to the reel or even breakage of the fan-shaped plate, and provides a uncoiler support head with a guide sleeve.

[0005] The specific scheme of the utility model is: a support head of a uncoiler with a guide sleeve, comprising a support head, a mounting shaft and a driving mechanism, the support head is rotatably mounted with a rotating shaft, a reel is provided at one end of the rotating shaft, a fan-shaped plate is covered on the surface of the reel, and the driving mechanism is used to drive the reel and the fan-shaped plate, and is characterized in that a guide structure is sleeved on the surface of the rotating shaft, the guide structure is conical, the diameter of one end of the guide structure away from the support head is larger than the diameter of the fan-shaped plate in the reduced diameter state, the guide structure comprises a guide sleeve and a reinforcement sleeve, the guide sleeve is sleeved on the surface of the rotating shaft and is detachably connected to the reel, the surface of the guide sleeve is provided with a reinforcement sleeve, and the guide sleeve is detachably connected to the reinforcement sleeve.

[0006] According to the above technical solution, the guide structure can effectively guide the steel coil when feeding, avoiding jamming and collision with the fan-shaped plate, and can also be disassembled and replaced by bolts.

[0007] Furthermore, a sliding structure is evenly distributed on the surface of the reinforcement sleeve, and the sliding structure includes a movable hole and a ball. The movable hole is arranged on the surface of the reinforcement sleeve, and a ball is movably installed inside the movable hole. The maximum diameter of the movable hole is smaller than the maximum diameter of the ball.

[0008] According to the above technical solution, by installing a sliding structure on the surface of the reinforcing sleeve, the smoothness of the steel coil can be improved during feeding, and wear caused by hard friction between the steel coil and the reinforcing sleeve can be avoided.

[0009] Furthermore, the diameters of the movable hole and the ball gradually increase from right to left.

[0010] According to the above technical solution, the movable hole and the ball diameter gradually increase from right to left, which facilitates the loading of the steel coil, avoids the steel coil being stuck by the steel ball, and ensures the smoothness of the ball-assisted movement of the steel coil.

[0011] Furthermore, the reinforcing sleeve and the ball are both made of ultra-high strength steel.

[0012] According to the above technical solution, the hardness of the reinforcing sleeve and the ball can be effectively improved by using ultra-high strength steel material, thereby improving their wear resistance.

[0013] Furthermore, the angle between the conical surface of the guide structure and the horizontal line of the axis of the guide structure is 15°, and the diameter of the end of the guide structure away from the support head is 10mm~15mm larger than the diameter of the sector plate in the reduced diameter state.

[0015] Furthermore, the reinforcement sleeve is wrapped around the surface of the guide sleeve.

[0016] According to the above technical solution, the guide sleeve can be effectively protected from wear by wrapping the reinforcing sleeve on the surface of the guide sleeve.

[0017] Compared with the prior art, the utility model has the following advantages: the uncoiler support head with a guide sleeve is installed with a guide sleeve to play a guiding role, thereby avoiding jamming between the inner ring jaws of the steel coil and the reel and the fan-shaped plate, thereby improving production efficiency, and also avoiding direct collision between the steel coil and the reel and the fan-shaped plate during feeding, thereby causing damage to the reel or even breakage of the fan-shaped plate, thereby greatly improving the service life of the equipment and reducing the maintenance cost of the equipment, and further installing a reinforcement sleeve and a ball bearing, thereby effectively improving the smoothness of feeding and avoiding hard friction between the steel coil and the reinforcement sleeve, and at the same time the reinforcement sleeve can effectively protect the guide sleeve, thereby improving the service life of the guide sleeve, thereby greatly improving the practicality of the uncoiler support head with the guide sleeve.

DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] See also Figure 1-6The present embodiment is a support head of an unwinding machine with a guide sleeve, which is composed of a support head 1, a mounting shaft 2 and a driving mechanism 3. The support head 1 is used to be rotatably connected with the rotating shaft 4 to assist the reel 5 to rotate and support it. At the same time, the internal bearing of the support head 1 can be withdrawn from the rotating shaft 4. The mounting shaft 2 is used to be connected with the driving mechanism 3. The driving mechanism 3 is used to drive the reel 5 to rotate and the fan-shaped plate 6 to expand and reduce the diameter through the mounting shaft 2. The end of the rotating shaft 4 away from the support head 1 is fixedly connected with the reel 5. The surface of the reel 5 is provided with a fan-shaped plate 6. The fan-shaped plate 6 is used to increase the diameter of the reel 5 to facilitate the loading and processing of the steel coil tensioning. The surface of the rotating shaft 4 is sleeved with a guide structure 7. The guide structure 7 is conical and the end of the guide structure 7 away from the support head 1 is the large head end. And the diameter of the big head end is 5 mm larger than the diameter of the sector plate 6 in the reduced diameter state. The guide structure 7 is composed of a guide sleeve 8 and a reinforcement sleeve 9. The guide sleeve 8 is used for guiding when the steel coil is loaded to prevent the steel coil from directly hitting the reel 5. The middle part of the guide sleeve 8 is hollowed out and arranged on the surface of the rotating shaft 4. At the same time, a screw hole a10 is provided on the surface of the guide sleeve 8, and a screw hole b11 is also provided on the surface of the reel 5. The guide sleeve 8 is fixed by connecting with a bolt 12, which is convenient for the installation and disassembly of the guide sleeve 8. At the same time, a reinforcement sleeve 9 is provided on the surface of the guide sleeve 8. The middle part of the reinforcement sleeve 9 is hollowed out and passes through the rotating shaft 4 and then wrapped on the surface of the guide sleeve 8. The screw hole c13 on the surface of the reinforcement sleeve 9 corresponds to the screw hole a10 of the guide sleeve 8. Finally, the bolt 12 is passed through the two screw holes and then fixed to the screw hole b11 of the reel 5, which is convenient for the disassembly of the reinforcement sleeve 9.

[0027] Furthermore, the angle between the conical surface of the guide structure 7 and the horizontal line of the axis of the guide structure 7 itself is 15°, and the diameter at the large end of the guide structure 7 is 10mm~15mm larger than that in the reduced diameter state, which is convenient for feeding and guiding the steel coil.

[0028] Furthermore, the reinforcing sleeve 9 wraps the surface of the guide sleeve 8 , thereby improving the strength of the guide sleeve 8 and reducing the wear of the guide sleeve 8 .

[0029] The working principle of this embodiment is as follows: when installing, first pull the support head 1 away from the rotating shaft 4, then sleeve the guide sleeve 8 on the surface of the rotating shaft 4, and install the large end of the guide sleeve 8 close to the direction of the fan-shaped plate 6, and finally pass the reinforcing sleeve 9 through the rotating shaft 4 to make it fit the surface of the guide sleeve 8, and finally fix it to the screw hole b11 of the winding drum 5 through the bolt 12 through the screw hole c13 on the reinforcing sleeve 9 and the screw hole a10 on the guide sleeve 8, and finally connect the mobile support head 1 with its rotating shaft 4 to complete the installation. When using, first ensure that the fan-shaped plate 6 is in a reduced diameter state, and then the steel coil first passes through the guide structure 7, and the guide structure 7 props up the inner ring of the steel coil. Since the guide structure 7 is conical and the large end is higher than the sector plate 6 in the reduced diameter state by 10mm~15mm, it can play a guiding role when the steel coil is fed, so that the bending part of the jaws of the inner ring of the steel coil will not directly hit the sector plate 6 and the reel 5, and at the same time, it also avoids the problem of jamming during feeding, and greatly reduces the probability of jamming of the steel coil and breakage of the sector plate 6, greatly improving the service life of the sector plate 6 and the reel 5. At the same time, when the reinforcement sleeve 9 is worn out after long-term use, the bolt 12 can be directly removed to replace the reinforcement sleeve 9, which further improves the service life of the guide sleeve 8, thereby reducing the cost of use.

[0030] Embodiment 2

[0031] 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: a sliding structure is evenly distributed on the surface of the reinforcement sleeve 9, and the sliding structure is used to assist the smoothness of the steel coil when it moves on the guide structure 7. The sliding mechanism is composed of a movable hole 14 and a ball 15. The movable hole 14 is provided on the surface of the reinforcement sleeve 9, and the ball 15 is movably installed inside the movable hole 14. Since the maximum diameter of the movable hole 14 is smaller than the maximum diameter of the ball 15, the ball 15 is embedded in the movable hole 14 and can rotate without falling off.

[0032] Furthermore, the diameters of the movable hole 14 and the ball 15 gradually increase from right to left, which facilitates the loading and auxiliary movement of the steel coil.

[0033] Furthermore, the reinforcing sleeve 9 and the ball 15 are both made of ultra-high strength steel, thereby ensuring the wear resistance of the reinforcing sleeve 9 and the ball 15 and increasing their service life.

[0034] The working principle of this embodiment is as follows: when in use, first repeat the operation method of embodiment 1 for installation. When the steel coil is loaded, the steel coil first contacts the ball 15 on the guide sleeve 8. Since the steel ball gradually becomes larger and can rotate in the movable hole 14, it can assist the steel coil to move to one side for loading, avoiding hard friction between the steel coil and the reinforcement sleeve 9, improving the smoothness of loading, and also reducing the wear of the steel coil and the reinforcement sleeve 9, further improving the service life of the guide structure 7.
