Description

Technical Field

[0001] The utility model relates to the technical field of coiling devices, in particular to a coiling device for low-stamping cold-rolled strip steel production. Background Art

[0002] Cold rolled steel strip is made of hot rolled steel strip and steel plate, which is rolled into steel strip and thin plate by cold rolling mill at room temperature. In the production process, the produced cold rolled steel strip is usually directly coiled by coiling device for subsequent handling and processing.

[0003] Chinese patent authorization announcement No. CN216150704U discloses a coiling device for cold-rolled strip production, including a bottom plate, a pressing mechanism and a winding mechanism, the winding mechanism including a rotatably arranged winding roller, and the winding roller is arranged above the bottom plate, the outside of the winding roller is wound with cold-rolled strip steel to form a strip steel coil, the pressing mechanism is arranged on one side of the winding mechanism, to ensure that the strip steel fits perfectly on the strip steel coil, making the subsequent winding and rewinding of the cold-rolled strip steel more compact, solving the problem of loose winding caused by the strip steel not being tight before rewinding, ensuring the rewinding efficiency, and facilitating subsequent handling. The above-mentioned prior art solution has the following shortcomings: during use, the coiling device for cold-rolled strip production uses the elastic action of the spring to cause the pressure roller to generate lateral squeezing force on the winding roller to prevent the strip on the winding roller from loosening. However, in the actual operation process, as the strip is continuously wound, the compression of the spring increases continuously, thereby increasing the pressure of the pressure roller on the winding roller, thereby increasing the rolling friction between the two, increasing the rotational resistance of the winding roller, and then affecting the smoothness of winding. Therefore, there is room for improvement. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coiling device for low-stamping cold-rolled strip steel production, comprising a fixed table, a U-shaped frame is installed on the top of the fixed table, and an electromagnet is arranged on the bottom end surface of the U-shaped frame, guide holes are opened on both sides of the U-shaped frame, and T-shaped guide blocks are passed through the inside of the guide holes, the outer sides of the T-shaped guide blocks are connected to the outer sides of the U-shaped frame with automatic tensioning adjustment mechanisms, the inner sides of the T-shaped guide blocks are connected to iron rollers, and the outer sides of the iron rollers are provided with tensioning sleeves, and the tops of the fixed tables on both sides of the U-shaped frame are equipped with two first support plates arranged opposite to each other, and the two first support plates are arranged opposite to each other. Two upper and lower cleaning components are connected between the first support plates, and the spacing between the two cleaning components is adapted to the thickness of the cold-rolled strip. Lamp covers are connected to the upper and lower ends of the first support plates, and drying lamps are evenly installed on one end of the lamp cover close to the cleaning component to facilitate drying the cleaning component. Two second support plates are installed on the outermost side of the top of the fixed platform, and a winding roller is connected between the two second support plates. A servo motor is installed on the outer side of the second support plate on one side, and the output end of the servo motor is detachably connected to one end of the winding roller.

[0006] Preferably, the automatic tensioning adjustment mechanism includes a movable groove opened on the outside of the T-shaped guide block, and a movable rod passes through the inside of the movable groove, a spring is sleeved on the outside of the movable rod, one end of the movable rod extends to the outside of the movable groove and is welded with a pull plate, and sliders are installed on both sides of the pull plate close to the T-shaped guide block.

[0007] Preferably, a groove is correspondingly provided on the outside of the T-shaped guide block on one side of the sliding block, and the sliding block forms a front-and-rear sliding structure with the T-shaped guide block through the groove.

[0008] Preferably, an anti-loosening block is installed on one side of the slider close to the T-shaped guide block, and locking grooves are evenly opened on the outside of the T-shaped guide block on one side of the anti-loosening block, and one end of the anti-loosening block extends to the inside of the locking groove.

[0009] Preferably, the cross-section of the anti-loosening block is a right-angled trapezoid, the inclined surface of the anti-loosening block faces downward, and the locking grooves are distributed at equal intervals on the T-shaped guide block.

[0010] Preferably, the cleaning component comprises a rotating roller connected between the two first support plates, and an adhesive sticker is arranged on the outside of the rotating roller, a soft sticker is bonded to the outside of the adhesive sticker, and cleaning cotton is arranged on the outside of the soft sticker.

[0011] Preferably, the height of the cold-rolled steel strip between the cleaning components is higher than the height of the cold-rolled steel strip below the tensioning sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The cold-rolled steel strip is always in a tensioned state before winding by the attraction between the electromagnet and the iron roller, thereby preventing it from loosening after winding. The automatic tensioning adjustment mechanism, the locking groove, and the anti-loosening block are used to automatically adjust and fix the tensioning position of the tensioning sleeve. The special structure of the anti-loosening block prevents the tensioning sleeve from rising, thereby further preventing the cold-rolled steel strip from loosening. Since the tensioning force changes only with the looseness of the cold-rolled steel strip, it will not affect the winding effect of the winding roller, thereby ensuring the winding stability of the cold-rolled steel strip.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 The utility model provides an embodiment: a coiling device for low-stamping cold-rolled strip production, comprising a fixed table 1, a U-shaped frame 6 is installed on the top of the fixed table 1, and an electromagnet 7 is arranged on the bottom end surface of the U-shaped frame 6, guide holes 13 are opened on both sides of the U-shaped frame 6, and T-shaped guide blocks 14 are penetrated inside the guide holes 13, and the outer sides of the T-shaped guide blocks 14 are connected to the outer sides of the U-shaped frame 6 with automatic tensioning adjustment mechanisms 15;

[0024] The automatic tensioning adjustment mechanism 15 includes a movable groove 1501 provided on the outside of the T-shaped guide block 14, and a movable rod 1502 is passed through the inside of the movable groove 1501, a spring 1503 is sleeved on the outside of the movable rod 1502, one end of the movable rod 1502 extends to the outside of the movable groove 1501 and is welded with a pull plate 1504, and sliders 1505 are installed on both sides of the pull plate 1504 close to the T-shaped guide block 14;

[0025] A groove is correspondingly formed on the outside of the T-shaped guide block 14 on one side of the slider 1505, and the slider 1505 forms a forward and backward sliding structure with the T-shaped guide block 14 through the groove;

[0026] An anti-loosening block 17 is installed on one side of the slider 1505 close to the T-shaped guide block 14, and locking grooves 16 are evenly opened on the outside of the T-shaped guide block 14 on one side of the anti-loosening block 17, and one end of the anti-loosening block 17 extends to the inside of the locking groove 16;

[0027] The cross section of the anti-loosening block 17 is a right-angled trapezoid, the inclined surface of the anti-loosening block 17 faces downward, and the locking grooves 16 are distributed at equal intervals on the T-shaped guide block 14;

[0028] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when in use, the structural characteristics of the anti-loosening block 17 are utilized to produce an outward sliding effect between its lower end surface and the locking groove 16, and the elastic effect of the spring 1503 is cooperated so that the tensioning sleeve 12 can produce an automatic downward movement effect, but cannot automatically move upward, so that the loose cold-rolled strip of the tensioning sleeve 12 produces a tensioning effect, and the tensioning force is ensured not to be loosened. Under the limiting effect of the cleaning components 3 on the left and right sides on the cold-rolled strip, the change of the tensioning force only changes with the loosening effect of the cold-rolled strip, and will not affect the winding effect of the winding roller 9 on the cold-rolled strip, so that the effect is better;

[0029] The inner side of the T-shaped guide block 14 is connected to an iron roller 11, and the outer side of the iron roller 11 is sleeved with a tensioning sleeve 12. The tops of the fixed platforms 1 on both sides of the U-shaped frame 6 are equipped with two first support plates 2 arranged opposite to each other, and two cleaning components 3 arranged at intervals are connected between the two first support plates 2 arranged opposite to each other.

[0030] The cleaning assembly 3 includes a rotating roller 301 connected between the two first support plates 2, and an adhesive sticker 302 is arranged outside the rotating roller 301, a soft sticker 303 is adhered to the outside of the adhesive sticker 302, and a cleaning cotton 304 is arranged outside the soft sticker 303;

[0031] The height of the cold-rolled steel strip between the cleaning components 3 is higher than the height of the cold-rolled steel strip below the tensioning sleeve 12;

[0032] Specifically, Figure 1 and Figure 5 As shown, when in use, the bonding effect between the sticky sticker 302 and the soft sticker 303 is utilized to realize the detachability of the cleaning cotton 304, thereby facilitating the separate detachment and cleaning of the cleaning cotton 304;

[0033] The spacing between the upper and lower cleaning components 3 is adapted to the thickness of the cold-rolled strip steel. The upper and lower ends of the first support plates 2 are connected with lampshades 4, and a drying lamp 5 is evenly installed on one end of the lampshade 4 close to the cleaning component 3 to facilitate drying the cleaning component 3. Two second support plates 8 arranged opposite to each other are installed on the outermost side of the top of the fixed table 1, and a winding roller 9 is connected between the two second support plates 8 arranged opposite to each other. A servo motor 10 is installed on the outer side of the second support plate 8 on one side, and the output end of the servo motor 10 is detachably connected to one end of the winding roller 9.

[0034] Working principle: When the utility model is used, the cold-rolled steel strip is first passed through between the upper and lower cleaning components 3 of the first group, and then passed through the bottom of the tension sleeve 12. After the cold-rolled steel strip passes through between the upper and lower cleaning components 3 of the second group, it is connected to the winding roller 9, and the servo motor 10 is started to rotate, so that the winding roller 9 drives the cold-rolled steel strip to rotate and wind;

[0035] Secondly, the friction between the upper and lower cleaning cottons 304 on the cold-rolled steel strip is used to block the debris on the surface of the cold-rolled steel strip and absorb the water stains on the surface of the cold-rolled steel strip. During this period, the drying lamp 5 is synchronously started to irradiate and dry the cleaning cotton 304 to reduce the contamination of the surface of the cold-rolled steel strip by the water stains. At the same time, the bonding effect between the soft surface sticker 303 and the adhesive surface sticker 302 is used to facilitate the regular disassembly and replacement of the cleaning cotton 304.

[0036] Finally, during the winding process, the electromagnet 7 is started synchronously to generate a downward attraction force on the cold-rolled strip and the iron roller 11 above, thereby causing the loose cold-rolled strip to be tightened downward. At the same time, when the iron roller 11 moves downward, the T-shaped guide block 14 slides downward along the guide hole 13. Since the lower end face of the anti-loosening block 17 is an inclined surface, the anti-loosening block 17 can slide out of the locking groove 16 and move downward, and at the same time, the spring 1503 is compressed to move the pull plate 1504 outward. When the T-shaped guide block 14 slides down to a certain extent, due to the elastic reset effect of the spring 1503, the anti-loosening block 17 is inserted into the next locking groove 16 accordingly, and since the upper end face of the anti-loosening block 17 is a plane, the T-shaped guide block 14 is prevented from rising back, and the tensioning sleeve 12 is avoided from rising, thereby ensuring that the tensioning effect of the tensioning sleeve 12 on the cold-rolled strip continues.
