Description

Technical Field

[0001] The utility model relates to the technical field of uncoilers, in particular to a steel belt pressing device for uncoilers. Background Art

[0002] The uncoiler is one of the essential and important 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, and the other is to send the head of the steel strip into the leveling machine by rotating with the cooperation of the straightening machine. In order to prevent the steel strip from shaking up and down before being sent to the clamping roller inside the leveling machine, causing twisting and damage, the existing uncoiler is equipped with a corresponding clamping device at the delivery end to limit the delivered steel strip.

[0003] Publication No. "CN216175432U" provides a steel strip clamping device for an uncoiler. A guide mechanism is arranged on both sides of the lifting mechanism. The guiding function of the guide block and the guide rod of the guide mechanism is utilized to enable the roller to be lifted and lowered along a fixed trajectory under the drive of the lifting mechanism, thereby ensuring that the roller can be accurately pressed on the steel strip.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the clamping device can support and clamp the steel strip through the rollers, the rollers alone cannot effectively limit and clamp the upward displacement and vibration of the steel strip, resulting in the steel strip being prone to upward vibration when being sent out by the uncoiler. Therefore, the clamping and limiting effect needs to be further improved. Utility Model Content

[0025] Please refer to Figure 1-5 , the present invention provides a technical solution:

[0026] Embodiment 1:

[0027] A steel strip pressing device for an uncoiler, including a steel strip 1 to be processed, a support frame 4 and an uncoiler body 5. The steel strip 1 to be processed is installed at the front end of the uncoiler body 5, and a support frame 4 is installed on the right side of the uncoiler body 5. The shape of the support frame 4 is a rectangular frame with a hollow center. The support frame 4 in the shape of a rectangular frame with a hollow center can support the limiting roller 32 and the supporting roller 25. On the left and right sides of the inner wall of the support frame 4, limiting grooves 42 are symmetrically provided. The limiting grooves 42 are matched with the upper support seat 33 and the lower support seat 26. The limiting grooves 42 can limit and guide the upper support seat 33 and the lower support seat 26, avoiding the situation of deviation or shaking of the upper support seat 33 and the lower support seat 26 during the lifting process. An inspection cover plate 41 is installed on the upper end surface of the support frame 4. The inspection cover plate 41 is a detachable structure. The detachable inspection cover plate 41 facilitates the later maintenance of the transmission worm 36 and the worm gear 37 inside the support frame 4 by the staff.

[0028] A supporting component 2 is arranged on the lower side inside the support frame 4, and the supporting component 2 is used for supporting and guiding the steel strip 1 to be processed. An auxiliary limiting component 3 is arranged on the upper side inside the support frame 4, and the auxiliary limiting component 3 is used for limiting and guiding the steel strip 1 to be processed, thereby avoiding the situation of up and down shaking of the steel strip 1 to be processed during the feeding process.

[0029] The supporting assembly 2 includes an electric hydraulic push rod 23, a bottom fixing plate 24, a supporting roller 25, a lower support seat 26 and a lower extension shaft 27. The electric hydraulic push rod 23 is installed at the middle position at the bottom of the supporting frame 4. The electric hydraulic push rod 23 is connected to the external control panel through a wire. The electric hydraulic push rod 23 can drive the supporting frame 4 to move up and down during operation, so that the staff can adjust the use height of the supporting frame 4 according to needs. A bottom fixing plate 24 is installed at the bottom of the electric hydraulic push rod 23. The bottom fixing plate 24 is installed and fixed to a specified position on the external cement floor through external expansion bolts. The bottom fixing plate 24 can support the electric hydraulic push rod 23 and the limit rod 22. A lower support seat 26 is installed on the lower side of the support frame 4. The lower support seat 26 can support the lower extension shaft 27. A supporting roller 25 is installed on the inner side of the support frame 4. The supporting roller 25 can support and guide the steel strip 1 to be processed through the first anti-slip sleeve 251 to prevent the steel strip 1 to be processed from being bent downward when being sent out by the uncoiler body 5.

[0030] The left and right end surfaces of the supporting roller 25 are symmetrically equipped with lower extension shafts 27, which can not only support the supporting roller 25, but also enable the supporting roller 25 to rotate. The left and right sides of the upper end surface of the bottom fixing plate 24 are symmetrically fixed with limit rods 22, and the limit rods 22 are connected to the bottom fixing plate 24 by welding. The left and right sides of the lower end surface of the support frame 4 are symmetrically provided with limit sleeve rods 21, and the limit sleeve rods 21 are connected to the support frame 4 by welding. The limit rod 22 matches, and the matching limit sleeve rod 21 and the limit rod 22 prevent the support frame 4 from deflecting or shaking during the lifting process, so as to ensure the stability of the support frame 4. The annular side of the supporting roller 25 is wrapped with a first anti-slip sleeve 251, and the first anti-slip sleeve 251 makes the annular side of the supporting roller 25 more anti-slip. The annular side of the lower extension shaft 27 is installed with a lower ball bearing 271, and the lower ball bearing 271 makes the lower extension shaft 27 rotate more smoothly.

[0031] Embodiment 2:

[0032] On the basis of Example 1, in this embodiment, by rotating the transmission worm 36 forward, the transmission worm 36 can drive the double-threaded screw 34 to reverse together through the worm gear 37, and the reversed double-threaded screw 34 will drive the limiting roller 32 and the supporting roller 25 to move synchronously inward through the upper support seat 33, the upper extension shaft 35, the lower support seat 26 and the lower extension shaft 27. Similarly, when the transmission worm 36 is reversed, the limiting roller 32 and the supporting roller 25 can move synchronously outward, so that the staff can match and adjust the spacing between the limiting roller 32 and the supporting roller 25 according to the thickness of the steel strip 1 to be processed, and the adjusted limiting roller 32 and the supporting roller 25 will clamp and limit the passing steel strip 1 to be processed to avoid up and down shaking and deviation of the steel strip 1 to be processed before being sent into the clamping roller inside the external leveling machine, thereby ensuring the feeding stability of the uncoiler body 5.

[0033] The auxiliary limiting assembly 3 includes a limiting roller 32, an upper support seat 33, a double-threaded screw 34, an upper extension shaft 35, a transmission worm 36 and a worm wheel 37. The upper support seat 33 is installed on the upper side of the support frame 4, and the upper support seat 33 can support the upper extension shaft 35. The limiting roller 32 is installed on the inner side of the support frame 4. The limiting roller 32 can press and limit the steel strip 1 to be processed to prevent the steel strip 1 from shaking upward during the delivery process. The upper extension shaft 35 is symmetrically installed on the left and right end surfaces of the limiting roller 32. The upper extension shaft 35 can not only In order to provide support and also enable the limiting roller 32 to rotate, internal threaded through holes are provided inside the upper support seat 33 and the lower support seat 26, and the internal threaded through holes are meshed with the double-threaded screw rod 34. A double-threaded screw rod 34 is arranged inside the upper support seat 33, and the external thread on the upper side of the annular side of the double-threaded screw rod 34 rotates in opposite directions to the external thread on the lower side of the annular side. The double-threaded screw rod 34, whose external thread on the upper side of the annular side and the external thread on the lower side of the annular side rotate in opposite directions, can drive the upper support seat 33 and the lower support seat 26 to move synchronously in opposite directions through the internal threaded through holes when rotating.

[0034] A worm wheel 37 is arranged on the upper side of the annular side of the double-threaded screw 34, and the worm wheel 37 is connected to the double-threaded screw 34 by welding. The worm wheel 37 can drive the double-threaded screw 34 to rotate. A transmission worm 36 is meshed with the rear side of the annular side of the worm wheel 37. The transmission worm 36 is connected to the rotating disk 31 and the follower ring 361 by welding. The transmission worm 36 can drive the worm wheels 37 on the left and right sides to rotate synchronously in the same direction, and the transmission worm 36 and the worm wheel 37 also have self-locking ability. A rotating disk 31 is arranged on the left end of the transmission worm 36. The rotating disk 31 is convenient for the staff to rotate the transmission worm 36 by hand, and a positioning screw 311 is installed on the upper side of the rotating disk 31. The positioning screw 311 can lock the rotating disk 31 to prevent the rotating disk 31 from rotating easily when not in use. A follower ring 361 is arranged on the left side of the annular side of the transmission worm 36, and an annular baffle 43 is installed on the upper side of the left end surface of the support frame 4. The follower ring 361 and the annular baffle 43 prevent the transmission worm 36 from being displaced during rotation and use. The annular side of the limiting roller 32 is wrapped with a second anti-slip sleeve 321. The second anti-slip sleeve 321 makes the annular side of the limiting roller 32 more anti-slip. The upper ball bearing 351 is installed on the annular side of the upper extension shaft 35. The upper ball bearing 351 makes the upper extension shaft 35 rotate more smoothly.

[0035] Working principle: Before the unwinder body 5 sends out the steel strip 1 to be processed, the staff first rotates the transmission worm 36 forward through the rotating disk 31, so that the forward-rotating transmission worm 36 drives the worm wheels 37 on the left and right sides to reverse synchronously, and the reversed worm wheels 37 will drive the double-threaded screws 34 on the left and right sides to reverse together, and then the reversed double-threaded screws 34 drive the limiting rollers 32 and the supporting rollers 25 to move synchronously inward through the upper support seat 33, the upper extension shaft 35, the lower support seat 26 and the lower extension shaft 27. Similarly, When the transmission worm 36 is reversed, the limiting roller 32 and the supporting roller 25 can be moved outward synchronously, so that the staff can adjust the distance between the limiting roller 32 and the supporting roller 25 according to the thickness of the steel strip 1 to be processed. After the adjustment is completed, the positioning screw 311 is tightened with the help of an external wrench to prevent the rotating disk 31 from rotating when not in use. In this process, the distance between the first anti-slip sleeve 251 and the second anti-slip sleeve 321 needs to match the thickness of the steel strip 1 to be processed, and the first anti-slip sleeve 251 cannot be tightened. The spacing between the anti-slip sleeve 251 and the second anti-slip sleeve 321 is smaller than the steel strip 1 to be processed, so as to avoid the steel strip 1 to be processed being unable to pass through the first anti-slip sleeve 251 and the second anti-slip sleeve 321 due to the small spacing; then the staff can insert the head of the steel strip 1 to be processed on the uncoiler body 5 between the first anti-slip sleeve 251 and the second anti-slip sleeve 321 and the internal clamping roller of the external leveling machine in sequence; at this time, the uncoiler body 5 can be started to make the uncoiler body 5 send out the steel strip 1 to be processed. During this process, the supporting roller 25 and the limiting roller 32 will clamp, limit and guide the passing steel strip 1 to be processed, so as to avoid the steel strip 1 to be processed from shaking up and down and deviating before being sent into the internal clamping roller of the external leveling machine, so as to ensure the feeding stability of the uncoiler body 5, and in the later use process, the staff only needs to control the electric hydraulic push rod 23 to perform telescopic action to adjust the use height of the support frame 4, so that the staff can adjust the use height of the supporting roller 25 and the limiting roller 32 according to the needs.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
