Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel processing, in particular to a positioning device for a stainless steel belt slitting machine. Background Art

[0002] Slitting machines are usually used to unwind, longitudinally cut and rewind stainless steel into several coils of required width. Steel plates need to go through a rolling process before slitting. In order to ensure the quality of slitting, the positioning of the steel plates before the rolling process of cutting is particularly important.

[0003] There is a Chinese patent with the publication number CN213671521U, which discloses a positioning mechanism for a stainless steel slitting machine, which facilitates pressing down and fixing both sides of the top of the steel plate according to the thickness of different stainless steel plates through a pressing assembly. The pressing assembly includes fixed plates fixedly arranged on both sides of the bottom of the moving plate, a U-shaped mounting seat slidably arranged between the fixed plates, a positioning roller rotatably installed in the U-shaped mounting seat, and a threaded barrel fixedly connected to the middle of the moving plate, a threaded rod is connected to the threaded barrel, a rotating hand wheel is fixedly connected to the top of the threaded rod, and the bottom end of the threaded rod is rotatably connected to the top surface of the U-shaped mounting seat; a mounting groove is opened on the inner side surface of the fixed plate, a stabilizing rod is arranged in the mounting groove, a stabilizing block is movably sleeved on the stabilizing rod body, and the stabilizing block is fixedly connected to the top of the side surface of the U-shaped mounting seat.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments 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.

[0022] Please refer to Figure 1 - Figure 3 The present embodiment provides a positioning device for a stainless steel strip slitting machine, comprising a base 1, a beam 2 installed on the base 1, a plurality of pressing components installed on the beam 2, the pressing components comprising a U-shaped fixing plate 31 installed on the beam 2, a U-shaped mounting seat 32 vertically slidably connected to the fixing plate 31, a positioning roller 33 rotatably connected between the mounting seats 32, a threaded rod 34 fixedly connected to the top of the mounting seat 32, a threaded sleeve 35 threadedly connected to the threaded rod 34 rotatably connected to the fixing plate 31; in addition, a synchronous driving member is included, which is used to drive all the threaded sleeves 35 to rotate simultaneously, thereby realizing synchronous adjustment of all the pressing components. The synchronous drive member includes a motor 41 and a connecting column 42 respectively mounted on both sides of the top of the crossbeam 2, a first sprocket 43 is fixedly connected to the shaft end of the motor 41, a second sprocket 44 is rotatably connected to the connecting column 42, a chain 45 is sleeved on the outer sides of the first sprocket 43 and the second sprocket 44, a third sprocket 46 is coaxially fixedly connected to the threaded sleeve 35, and the third sprocket 46 is meshed with the chain 45. Further, the threaded sleeve 35 and the fixed plate 31 should be rotated through a bearing, and the bearing should be selected to have both axial load and radial load, such as a double-row deep groove ball bearing or a tapered roller bearing, to ensure that the threaded sleeve 35 is not prone to axial movement in the vertical direction.

[0023] The following is a further introduction in combination with specific usage scenarios. When adjusting the positioning roller 33 on all the downward pressure components, the motor 41 is started, and the chain 45 is moved under the drive of the first sprocket 43 and the second sprocket 44, and all the threaded sleeves 35 are further rotated under the cooperation of the chain 45 and the third sprocket 46. Since the mounting seat 32 and the fixed plate 31 are vertically slidingly connected, the spiral cooperation between the threaded sleeve 35 and the threaded rod 34 during rotation will drive the mounting seat 32 to slide vertically, thereby realizing the adjustment of the height of the positioning roller 33, so that the positioning roller 33 can be pressed against the top surface of the stainless steel plate. It should also be noted here that the first sprocket 43, the second sprocket 44, the third sprocket 46, the chain 45 and the motor 41 are used to jointly drive the threaded sleeve 35 to operate, so that the synchronization and accuracy of the rotation of the threaded sleeve 35 can be ensured, and finally the purpose of synchronously adjusting the height of all the positioning rollers 33 is achieved, and the height of all the positioning rollers 33 is always at the same height, which improves the synchronization and quickness of the height adjustment of all the positioning rollers 33 as a whole, and the adjustment accuracy is relatively high, thereby improving the overall adjustment efficiency of the device.

[0024] Reference Figure 1 - Figure 3 As a specific implementation of the embodiment of the present application, a plurality of slots 21 are evenly arranged on the crossbeam 2, at least two plug-in posts 51 matching the size of the slots 21 are fixedly connected to the fixing plate 31, and a locking pin 52 is detachably installed at one end of the plug-in post 51 away from the fixing plate 31.

[0025] In combination with specific usage scenarios, when in use, select the appropriate number of pressing components according to the width of the steel plate to be processed, and install the pressing components in the appropriate position. Specifically, first pull out the locking pin 52 on the fixing plate 31, then insert the plug-in column 51 on the fixing plate 31 into the slot 21 at the appropriate position on the beam 2, and then insert the locking pin 52 into the plug-in column 51 to ensure that the fixing plate 31 and the beam 2 are relatively fixed, so that the installation of a pressing component is realized. In this way, the top surface of steel plates of different widths can be pressed and positioned.

[0026] Reference Figure 1 or Figure 2 As a specific implementation of the embodiment of the present application, it also includes a controller electrically connected to the motor 41 and a distance sensor 6 installed on the mounting base 32. The distance sensor 6 is electrically connected to the controller. It should be noted here that the distance between the distance sensor 6 and the bottom end of the positioning roller 33 should be known.

[0027] In combination with specific usage scenarios, when performing strip processing on stainless steel plates, the distance from the steel plate to the distance sensor 6 is collected by using the distance measuring sensor 6. The distance between the positioning roller 33 and the steel plate can be obtained based on this distance and the distance between the distance measuring sensor 6 and the bottom of the positioning roller 33. When the distance measuring sensor 6 transmits the signal to the controller in a timely manner, the controller controls the operating status of the motor 41 in a timely manner, thereby ensuring that the motor 41 is braked in a timely manner to avoid indentations on the steel plate caused by excessive downward pressure, thereby improving the overall adjustment accuracy and convenience of the device.

[0028] Reference Figure 1 and Figure 2 As a specific implementation of the embodiment of the present application, a protective shell 7 is installed on the beam 2, and the first sprocket 43, the second sprocket 44, the third sprocket 46 and the chain 45 are all located in the protective shell 7.

[0029] In combination with specific usage scenarios, the first sprocket 43, the second sprocket 44 and the chain 45 can all be covered in the shell through the protective shell 7. This not only improves the safety of the operating environment of the device, but also ensures that no debris will appear between the sprocket and the chain 45, thereby ensuring the stability and reliability of the device adjustment.

[0030] Reference Figure 2 or Figure 3 As a specific implementation of the embodiment of the present application, a flange 8 is welded at the bottom end of the threaded rod 34, and the flange 8 is fixed to the mounting seat 32 by bolts.

[0031] In combination with specific usage scenarios, a flange 8 is welded to the bottom end of the threaded rod 34, and the flange 8 is fixed to the mounting seat 32 with bolts to achieve a fixed connection between the threaded rod 34 and the mounting seat 32. This installation not only facilitates the assembly between the mounting seat 32 and the threaded rod 34, but also facilitates subsequent disassembly and maintenance, thereby improving the convenience of disassembly and assembly of the device.

[0032] Reference Figure 1 - Figure 3 As a specific implementation of the embodiment of the present application, a plurality of dovetail grooves 321 are provided on both sides of the mounting seat 32, and a trapezoidal slide rail 311 that fits the dovetail groove 321 is fixedly connected to the fixed plate 31, and the fixed plate 31 and the mounting seat 32 are slidably connected through the cooperation of the trapezoidal slide rail 311 and the dovetail groove 321.

[0033] In combination with specific usage scenarios, the cooperation between the multiple dovetail grooves 321 on the mounting seat 32 and the trapezoidal slide rail 311 on the fixed plate 31 can ensure the connection stability between the fixed plate 31 and the mounting seat 32, providing a stable support environment for the installation of the positioning roller 33, and the cooperation between the multiple dovetail grooves 321 and the trapezoidal slide rail 311 can also ensure that the up and down sliding of the mounting seat 32 is more linear and straight, and the dovetail grooves and the trapezoidal slide rail 311 can also make the sliding between the mounting seat 32 and the fixed plate 31 more stable, thereby improving the stability of the adjustment of the positioning roller 33.

[0034] Reference Figure 3 As a specific implementation of the embodiment of the present application, a layer of rubber pad 9 is bonded to the outer side of the positioning roller 33.

[0035] In combination with specific usage scenarios, since the stainless steel plates cut by the slitting machine are generally relatively thin, if the surface quality of the positioning roller 33 is too hard, it may cause slight indentations on the surface of the steel plate when it contacts the steel plate. The rubber pad 9 can utilize the characteristics of the rubber pad 9 to not only ensure that the steel plate is pressed tighter, making the top surface positioning of the steel plate more stable, but also reduce the problem of indentations, thereby ensuring the surface quality of the steel plate.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
