Description

Technical Field

[0001] The utility model relates to the technical field of steel material processing equipment, and specifically designs a stainless steel belt slitting machine. Background Art

[0002] Stainless steel strips are usually of standard width during the production process. During further processing, a slitting machine is used for cutting according to production requirements to cut the width of the steel strip into the required width. This process is completed with the help of a slitting machine. The slitting machine includes an uncoiler, a longitudinal shear, a rewinder, etc. When the rewinder winds the slit steel strip, it is necessary to use a limiting structure to limit the position of the steel strip to ensure that the steel strip is not wound into a tower shape; the limiting mechanism usually includes a rotating shaft and a baffle installed on the rotating shaft. The baffles are arranged in pairs, and the distance between the baffles arranged in pairs is the width of the steel strip that needs to be wound. The baffles are used to limit the two sides of the steel strip to achieve the positioning of the steel strip when it is wound.

[0003] For example, in the patent application with the publication number CN218016088U, the steel strip slitting machine is provided with a support plate, the support plate is provided with a vertical chute, a first winding roller is movably installed under the chute for winding a narrow steel strip, a plurality of sliders are movably installed in the chute, and a plurality of second winding rollers are respectively installed on the plurality of sliders for winding the remaining plurality of narrow steel strips. Workers can reduce and increase the second winding rollers by themselves according to the number of narrow steel strips. If the worker reduces the narrow steel strips from three to two, the upper slider is allowed to slide along the chute to drive the upper second winding roller installed on the slider to move upward and leave the chute, so that the upper second winding roller will not hinder the worker's operation; if the worker increases the narrow steel strips from three to four, the new slider is allowed to move downward along the chute to be installed on the support plate, and the new second winding roller is installed in front of the slitting knife, so that the four narrow steel strips are respectively wound on the first winding roller and the three second winding rollers. Since the four rolls of narrow steel strips are respectively located on different winding rollers, it is convenient for the worker to take them out.

[0004] The baffle of the existing limiting mechanism is fixedly installed on the outside of the rotating shaft. The limiting mechanism can only limit and guide the steel strip of a specific width. In addition, the baffle will be worn and thinned due to long-term contact with the side of the steel strip, which leads to an increase in the distance between the two paired baffles, thereby reducing the limiting and guiding effect of the baffle on the steel strip, which is not conducive to the winding of the steel strip, especially the steel strip with a smaller width.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] In the description of the present utility model, unless otherwise specified, "multiple" means two or more than two; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] like Figure 1-Figure 4 As shown, a stainless steel strip slitting machine provided by an embodiment of the utility model includes a machine body 1, a winding roller 11 on the machine body 1, a limiting assembly 2 is also installed on the machine body 1, the limiting assembly 2 includes a mounting frame 21 rotatably installed on the top of the machine body 1, a rotating shaft 22 is rotatably installed on the mounting frame 21, a material blocking assembly 3 is installed on the rotating shaft 22, the material blocking assembly 3 includes a sleeve 31 sleeved on the rotating shaft 22, two groups of push rings 32 are screwed on the outside of the sleeve 31, and two groups of annular baffles 33 are symmetrically installed on the outside of the sleeve 31, when the two push rings 32 rotate, the corresponding annular baffles 33 are pushed to move along the axial direction of the sleeve 31.

[0028] One end of each of the two push rings 32 is rotatably connected to a connecting ring 321 , and the connecting ring 321 is detachably connected to the corresponding annular baffle 33 .

[0029] The winding roller 11 is rotatably mounted on the body 1, and in specific implementation, the winding roller 11 generally adopts an expandable and contractible structure to facilitate the smooth removal of the wound steel coil. A driving device for driving the winding roller 11 to rotate is arranged in the body 1. This is a prior art and can be directly applied without further elaboration. When the device is in use, the rotating shaft 22 is pressed toward the winding roller 11 by the mounting frame 21, so that the annular baffle 33 of the material blocking assembly 3 can contact the surface of the winding roller 11. The annular baffle 33 is a disc-shaped plate with a circular hole in the middle. At this time, the two groups of annular baffles 33 installed on the sleeve 31 of the rotating shaft 22 will block the two sides of the steel strip to be wound, so that the steel strip cannot be offset during the winding process. As the steel strip is wound, the mounting frame 21 gradually rotates to adjust the position of the rotating shaft 22 so that the distance between the rotating shaft 22 and the winding roller 11 can adapt to the winding thickness of the steel strip.

[0030] When the annular baffle 33 is worn, the push ring 32 screwed to the outside of the rotating sleeve 31 is connected to the connecting ring 321, and the push ring 32 is rotatably connected to one end of the annular baffle 33. Figure 2 and Figure 4 As shown, the connecting ring 321 is detachably connected to the corresponding annular baffle 33. Optionally, the connecting ring 321 is connected to the corresponding annular baffle 33 by bolts. When the push ring 32 is rotated, the push ring 32 spirals outside the sleeve 31 and pushes or pulls the annular baffle 33 to move axially along the sleeve 31, thereby adjusting the position of the annular baffle 33.

[0031] The stainless steel strip slitting machine provided by the utility model is achieved by threading the push ring 32 with the sleeve 31, and rotatably connecting the annular baffle 33 with the annular baffle 33 through the connecting ring 321, so that the push ring 32 can push the annular baffle 33 to move axially along the sleeve 31 when spirally moving outside the sleeve 31, thereby achieving the distance adjustment between the two baffles on the same sleeve 31, thereby calibrating the position of the worn annular baffle 33, ensuring the limiting effect of the annular baffle 33 on the winding of the steel strip, and at the same time making the distance between the two annular baffles 33 adjustable to accommodate the winding of steel strips of more sizes.

[0032] Furthermore, one side of the two connecting rings 321 protrudes from the corresponding annular baffle 33 to form a first ring 322, and one side of the annular baffle 33 protrudes from the corresponding connecting ring 321 to form a second ring 331. The second ring 331 cooperates with the first ring 322. An elastic pin is arranged in the first ring 322 along its own radial direction, and a pin hole for cooperating with the elastic pin is opened in the second ring 331 along its own radial direction.

[0033] The elastic pin includes a pin 323 arranged along the radial direction of the first ring 322 and a spring 324 mounted on the pin 323. A cylindrical cavity is opened in the first ring 322 along its own radial direction, and both ends of the pin 323 pass through the outside of the first ring 322. The spring 324 is in the cavity, and the part of the pin 323 in the cavity is formed with a stopper 325 along its own circumference. The stopper 325 and the spring 324 cooperate with each other to limit the position of the pin 323.

[0034] Specifically, the provision of the first ring 322 and the second ring 331 increases the contact area between the annular baffle 33 and the connecting ring 321, so that after the plug 323 is inserted into the pin hole, the connecting ring 321 and the annular baffle 33 can be stably connected, ensuring that the connecting ring 321 and the annular baffle 33 can be displaced synchronously. In this embodiment, the first ring 322 and the second ring 331 have the same axial dimensions, and the first ring 322 is arranged on the outside or inside of the second ring 331. When the annular baffle 33 needs to be removed from the connecting ring 321, the plug 323 is pulled or pressed to move the plug 323 out of the corresponding pin hole to cancel the connection between the first ring 322 and the second ring 331.

[0035] Furthermore, the first ring 322 is arranged on the inner side of the second ring 331, and the stopper 325 is arranged on the side of the pin 323 in the cavity away from the second ring 331. A trapezoidal groove 311 is provided at the position corresponding to the pin 323 on the sleeve 31, and one end of the trapezoidal groove 311 extends to the end of the sleeve 31, and the trapezoidal groove 311 is provided along the axial direction of the sleeve 31. When in a natural state, the spring 324 pushes the stopper 325 to be on the side of the cavity corresponding to the central axis of the first ring 322, and at this time, the end of the pin 323 extends to the deepest part of the trapezoidal groove 311.

[0036] Specifically, the trapezoidal groove 311 is a right-angled trapezoid, and its right-angled side is located in the plane where the end of the sleeve 31 is located. Figure 4 As shown, in this embodiment, the connecting ring 321 has a first position and a second position along the axial direction of the sleeve 31:

[0037] When in the first position, the elastic force of the spring 324 pushes the stopper 325 to Figure 4 At this time, the latch 323 is inserted from the inner side of the first ring 322, that is, Figure 4 The lower end of the first ring 322 extends out, and the lower end of the latch 323 contacts the bottom of the trapezoidal groove 311, that is, the position with the largest depth. The latch 323 limits the position of the connecting ring 321 through the first ring 322, so that the connecting ring 321 cannot be driven to rotate when the push ring 32 rotates, thereby ensuring that the latch 323 is in Figure 4 The upper end of the middle part can always correspond to the pin hole opened on the second ring 331;

[0038] When in the second position, the latch 323 is in Figure 4 In the figure, the lower end of the latch 323 contacts the outer wall of the sleeve 31, and the stopper 325 squeezes the spring 324 to deform toward the upper end of the cavity. At the same time, the upper end of the latch 323 extends into the pin hole on the second ring 331, and the first ring 322 and the second ring 331 establish an indirect relationship. That is, when the latch 323 is in Figure 4When the push ring 32 is on the right side of the trapezoidal groove 311 in the figure, the push ring 32 can rotate to pull the annular baffle 33 to move leftward through the connecting ring 321, and can also push the annular baffle 33 to move rightward through the connecting ring 321.

[0039] The first position is closer to the end of the sleeve 31. Figure 2 As shown, the first position corresponds to the horizontal section of the trapezoidal groove 311, and the horizontal section of the trapezoidal groove 311 has the largest depth.

[0040] Furthermore, the mounting frame 21 includes a mounting rod, one end of which is rotatably mounted on the top of the body 1, a connecting frame is provided on one side of the mounting rod, one side of the connecting frame is fixed to the mounting rod, the rotating shaft 22 is rotatably connected to the other side of the connecting frame, and a driving member for driving the rotating shaft 22 to rotate is also installed on the connecting frame.

[0041] Specifically, the driving member is a motor installed on the connecting frame, and a belt pulley is installed at one end of the rotating shaft 22 and the output end of the motor. The two belt pulleys are connected by a belt drive. This is a prior art and will not be described in detail. When the steel belt is wound, the motor drives the rotating shaft 22 to rotate to reduce the friction of the sleeve 31 with the steel belt, wherein the rotation direction of the rotating shaft 22 is opposite to the rotation direction of the winding roller 11. In addition, a hydraulic rod for adjusting the angle of the mounting frame 21 is also provided on the machine body 1, such as Figure 1 As shown, the hydraulic rod is connected to one side of the mounting rod through a connecting piece. When the hydraulic rod is extended or retracted, it can drive the mounting rod to rotate, thereby adjusting the position of the connecting frame, so that the position of the rotating shaft 22 can be continuously adjusted according to the winding thickness of the steel strip outside the winding roller 11.

[0042] In another embodiment of the present invention, the annular baffle 33 includes two symmetrically arranged semicircular plates 332 , the inner diameters of the two semicircular plates 332 are equal to the inner diameters of the sleeve 31 , and the second ring 331 is composed of two semicircular rings, which are fixedly connected to the corresponding semicircular plates 332 .

[0043] Slide blocks 333 are symmetrically arranged on each semicircular plate 332 , and a slide groove is provided at a position on the sleeve 31 corresponding to the slide blocks 333 , and one end of the slide groove extends to the end of the sleeve 31 on the side where it is located.

[0044] Specifically, in order to facilitate the disassembly and replacement of the annular baffle 33, in the present embodiment, the annular baffle 33 is composed of two semicircular plates 332, and a semicircular hole is opened in the middle of the two semicircular plates 332 to facilitate being sleeved on the outside of the sleeve 31. When the semicircular plates 332 need to be replaced, the push ring 32 is screwed to make the push ring 32 spirally move toward the end of the sleeve 31 until it is removed from the end of the sleeve 31. When the connecting ring 321 reaches the above-mentioned first position with the push ring 32, the pin 323 is moved out of the corresponding pin hole. At this time, the connection between the first ring 322 and the second ring 331 is disconnected. After the push ring 32 is removed from the sleeve 31, the semicircular plate 332 can be slid along the slide groove to the end of the sleeve 31 for removal and replacement. It is convenient and quick and does not require the use of tools.

[0045] Furthermore, the inner annular surface of each semicircular plate 332 is roughened, and a rubber pad is provided on the circumferential surface of the sleeve 31 corresponding to the trapezoidal groove 311 , and the inner annular surface of each semicircular plate 332 is in full contact with the corresponding rubber pad.

[0046] Specifically, in the above embodiment, since the semicircular plates 332 are slidably installed on the sleeve 31, during the installation process of the semicircular plates 332, the semicircular plates 332 are first installed on the outside of the sleeve 31, and then the push ring 32 is screwed to the outside of the sleeve 31 again. It should be noted that before the push ring 32 is screwed to the sleeve 31, the pin 323 on the connecting ring 321 needs to be placed in the trapezoidal groove 311, and the connecting ring 321 is restricted by the pin 323 to prevent the connecting ring 321 from rotating with the push ring 32. Before the connecting ring 321 reaches the second position, in order to ensure that the semicircular rings on the semicircular plates 332 can be connected with the first The ring 322 fits tightly so that the pin hole and the end of the plug pin 323 are opposite. In this embodiment, the inner ring surface of each semicircular plate 332 is roughened, and a rubber pad is provided on the circumferential surface of the trapezoidal groove 311 on the sleeve 31. The semicircular plate 332 has a large resistance when sliding along the position where the rubber pad is set, so that the semicircular plate 332 can slide along the position where the rubber pad is set on the sleeve 31 only when it is subjected to sufficient thrust, so that when the connecting ring 321 moves from the first position to the second position, the semicircular ring on the semicircular plate 332 can fit tightly with the first ring 322, keeping the pin hole and the end of the plug pin 323 facing each other.

[0047] In another embodiment of the present invention, the sleeve 31 is fixedly mounted on the outside of the rotating shaft 22 by bolts.

[0048] Specifically, a plurality of screw holes for fixing the sleeve 31 are provided on the rotating shaft 22. Preferably, a countersunk hole is provided on the sleeve 31 at a position corresponding to the bolt. The sleeve 31 is fixed to the outside of the rotating shaft 22 by bolts. When the thread on the sleeve 31 is damaged and affects the threaded connection of the push ring 32, the sleeve 31 can be removed and replaced separately.

[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
