Description

Technical Field

[0001] This invention relates to the field of steel rolling equipment technology, and in particular to a side guide device for the front roller table of a coiling machine. Background Technology

[0002] Before leaving the factory, steel products typically need to be coiled into rolls or discs for easier transportation and storage. A coiling machine is an auxiliary device used to coil hot-rolled or cold-rolled steel. To facilitate the feeding of long strips of steel into the coiling machine, a side guide device is usually installed at the front roller conveyor. This side guide device restricts the conveying direction of the steel to ensure smooth feeding.

[0003] Common side guide devices are mostly long, strip-shaped plate structures, fixed to both sides above the front roller conveyor by cantilevered locating pins. When the wear-resistant plate below the side guide device is flat, while the outer surface of the front roller conveyor is cylindrical, the excessive clearance between the two can cause the steel strip to insert into the gap between the front roller conveyor and the side guide device. Therefore, to solve this problem, an arc structure matching the structure of the front roller conveyor is created in the bottom wear-resistant plate of the side guide device to improve the fit. Controlling the distance between the side guide device and the front roller conveyor then becomes a problem that needs to be solved.

[0004] In existing technologies, the height of the side guide device is usually adjusted by adding or removing shims below the side guide device. The height must be re-checked every time the side guide is replaced, which is a time-consuming and labor-intensive process that seriously affects the work progress.

[0005] In view of this, it is necessary to propose a side guide device for the front roller conveyor of the crimping machine to solve the above-mentioned defects. Summary of the Invention

[0006] The main objective of this invention is to provide a side guide device for the front roller conveyor of a crimping machine, which aims to solve the problem that the distance between the existing side guide device and the front roller conveyor needs to be frequently adjusted.

[0007] To achieve the above objectives, the present invention provides a side guide device for the front roller conveyor of a crimping machine, which is installed on the front cantilever of the crimping machine and located on both sides of the front roller conveyor, and includes a positioning column, a side guide body, a height adjustment mechanism, and a centering mechanism.

[0008] The positioning post is vertically fixed to the front cantilever, and the side guide body has positioning holes that penetrate its upper and lower surfaces. The side guide body is installed on the positioning post through the positioning holes and is spaced apart from the front roller conveyor.

[0009] Both the centering mechanism and the height adjustment mechanism are located on the periphery of the positioning hole. The centering mechanism includes at least two centering components circumferentially distributed on the periphery of the positioning hole. Each centering component abuts against the periphery of the positioning post and applies a radial force to the positioning post to make the positioning hole coaxial with the positioning post. The height adjustment mechanism is disposed on the front cantilever and passes through the side guide body to adjust the height of the side guide body and thus adjust the spacing distance between the side guide body and the front roller conveyor.

[0010] Preferably, the positioning hole includes a height adjustment section and a centering section that are connected to each other. The width of the height adjustment section is greater than the diameter of the centering section. The height adjustment mechanism includes a pad and a height adjustment component. The pad is disposed on the front cantilever and embedded in the height adjustment section. The positioning post passes through the pad and is installed in the centering section. The pad is spaced apart from the bottom surface of the side guide body. The height adjustment component passes through the pad and the side guide body to adjust the distance between the pad and the side guide body, thereby adjusting the height of the side guide body.

[0011] Preferably, there are multiple height adjustment components, each of which includes a positioning screw and an adjusting screw. The positioning screw passes through the pad, and the adjusting screw passes through the side guide body from the top and is threadedly connected to the positioning screw. Rotating the adjusting screw adjusts the gap between the pad and the side guide body.

[0012] Preferably, there are three height adjustment components, which are evenly distributed in a circle around the circumference of the positioning hole.

[0013] Preferably, the height adjustment mechanism further includes a rotating wheel installed at the end of each of the adjusting screws away from the front cantilever and a transmission belt that drives each of the rotating wheels to rotate simultaneously, thereby driving each of the adjusting screws to rotate synchronously.

[0014] Preferably, the rotating wheel is a sprocket and the transmission belt is a chain.

[0015] Preferably, the side guide body has a mounting groove, which is circumferentially distributed around the positioning hole and communicates with the positioning hole. Each centering component includes an elastic support and an ejector embedded in the mounting groove, and a pressure plate covering the elastic support and the ejector. The elastic support radially supports the ejector to move in the axial direction of the positioning post to squeeze the positioning post from multiple directions.

[0016] Preferably, there are multiple centering components, which are distributed circumferentially around the positioning post.

[0017] Preferably, the elastic support is a spring.

[0018] Preferably, the ejector has a T-shaped cross-section and includes a base plate and a top plate connected to the base plate. The top plate is in close contact with the elastic support and extends out of the mounting groove to contact the positioning post.

[0019] Compared with the prior art, the side guide device for the front roller conveyor of the crimping machine provided by the present invention has the following beneficial effects:

[0020] The side guide device for the front roller conveyor of the crimping machine provided by the present invention radially supports the positioning column through a plurality of centering components, so that the positioning hole and the positioning column are coaxially arranged. The side guide body is always horizontal relative to the front cantilever at the bottom. In this way, when the side guide body is leveled by the centering mechanism, the height of the side guide body is adjusted by the height adjustment mechanism, so that the distance between the side guide body and the front cantilever is always a vertical distance. This effectively ensures the spacing between the side guide body and the front roller conveyor, ensures adjustment accuracy, and effectively avoids the problem of the side guide device rubbing against the rotating front roller conveyor.

[0035] Please refer to the appendix. Figures 1-4This invention provides a side guide device for the front roller conveyor of a coiling machine. The side guide device 10 is mounted on the front cantilever 20 of the coiling machine and is located on both sides of the front roller conveyor 30 to restrict the conveying direction of steel. The side guide device 10 includes a positioning post 1, a side guide body 3, and a height adjustment mechanism 5 and a centering mechanism 7 disposed on the side guide body 3. The positioning post 1 is vertically fixed to the front cantilever 20. The side guide body 3 has positioning holes 31 penetrating its upper and lower surfaces, and the side guide body 3 is axially mounted on the positioning post 1 through the positioning holes 31. The centering mechanism 7 and the height adjustment mechanism 5 are both located around the positioning holes 31. The centering mechanism 7 includes at least two centering components 70 distributed circumferentially along the positioning hole 31. Each centering component 70 abuts against the circumferential side of the positioning post 1 and applies a radial force to the positioning post 1 to make the positioning hole 31 coaxial with the positioning post 1. The height adjustment mechanism 5 is disposed on the front cantilever 20 and passes through the side guide body 3 to adjust the height of the side guide body 3, thereby adjusting the gap distance between the side guide body 3 and the front roller conveyor 30. The centering mechanism is used to adjust the distance between the positioning post 1 and the positioning hole 31. By maintaining a coaxial relative position, the side guide body 3 is always horizontally positioned relative to the bottom front cantilever 20. Thus, when the side guide body 3 is leveled by the centering mechanism 7, the height of the side guide body 3 is adjusted by the height adjustment mechanism 5, ensuring that the distance between the side guide body 3 and the front cantilever 20 is always a vertical distance. This effectively guarantees the spacing between the side guide body 3 and the front roller conveyor 30, ensuring adjustment accuracy and effectively preventing the side guide device 10 from rubbing against the rotating front roller conveyor 30.

[0036] The side guide body 3 is cuboid in shape and is supported on the front cantilever 20. It is located on both sides of the front roller conveyor 30 to limit the position of the front roller conveyor 30 when conveying steel plates, ensuring that the steel plate is always conveyed between the two side guide devices 10. The bottom of the side guide body 3 is a wear-resistant plate with multiple arc-shaped grooves that match the outer circumferential contour of the front roller conveyor 30. The positioning hole 31 penetrates the side guide body 3. The positioning hole 31 is a round hole to match the shape of the positioning post 1. Of course, the positioning hole 31 can also be a waist-shaped hole or other irregularly shaped hole. In this embodiment, there are two positioning holes 31. Of course, in other embodiments, multiple positioning holes 31 can be formed on the side guide body 3 according to its length. It is worth mentioning that, in order to compensate for the thermal expansion and contraction of the side guide body, one circular positioning hole and one elliptical positioning hole can be formed.

[0037] Please see Figure 5Furthermore, the side guide body 3 is also provided with a plurality of mounting grooves 33. Preferably, there are three mounting grooves 33. The three mounting grooves 33 are circumferentially distributed on the periphery of the positioning hole 31 and communicate with the positioning hole 31. The mounting grooves 33 are circumferentially distributed on the periphery of the positioning hole 31. The mounting grooves 33 have a certain depth and communicate with the positioning hole 31 at the upper end to form a T-shaped groove.

[0038] Please see Figure 4 The positioning hole 31 is in the shape of an inverted T. The positioning hole 31 includes an adjustment section 311 and a centering section 313 that are connected to each other. The adjustment section 311 is square and the centering section 313 is cylindrical. The width of the adjustment section 311 is greater than the diameter of the centering section 313. The height adjustment mechanism 5 includes a pad 51 and a height adjustment component 53. The pad 51 is a square pad, which is disposed on the front cantilever 20 and embedded in the height adjustment section 311. The front cantilever 20 is located directly below the pad 51. The positioning post 1 passes through the pad 51 and is installed in the centering section 313 of the positioning hole 31. The pad 51 is spaced apart from the bottom of the side guide body 3. The height adjustment component 53 passes through both the pad 51 and the side guide body 3 to adjust the gap between the pad 51 and the side guide body 3 to adjust the height of the side guide body 3 on the front cantilever 20, thereby achieving the purpose of adjusting the interval distance between the side guide body 3 and the front roller conveyor 30.

[0039] Specifically, in this embodiment, the front cantilever is installed within the height adjustment section 311, and the pad 51 is embedded in the bottom of the height adjustment section 311. The height adjustment assembly 53 includes a positioning screw 531 and an adjusting screw 533. The positioning screw 531 extends from the bottom of the pad 51 through the upper surface of the pad 51. The adjusting screw 533 extends from the top of the side guide body 3 through the side guide body 3 and is connected to the positioning screw 531. The adjusting screw 533 is threadedly connected to the side guide body 3. The bottom of the adjusting screw 533 rests on the pad 51, and the positioning screw 531 passes through the pad 51 and connects to the end of the adjusting screw 533, so that the adjusting screw 533 and the... The positioning screw 531 is threaded, allowing adjustment of the gap between the pad 51 and the bottom of the side guide body 3 by rotating the adjusting screw 533. A smaller gap results in a lower height for the side guide body 3 and a smaller gap between it and the front roller conveyor 30; conversely, a larger gap results in a higher height for the side guide body 3 and a larger gap between it and the front roller conveyor 30. Adjusting the height of the side guide body 3 by rotating the adjusting screw 533, and thus the gap between it and the front roller conveyor 30, is convenient and precise. It eliminates the need to add or remove shims below the side guide body 3 to increase or decrease the height, ensuring accuracy and faster adjustment. However, it should be noted that if the gap between the side guide device and the front roller conveyor is too small in the height direction, the side guide device may rub against the rotating front roller conveyor; if the gap is too large, it increases the risk of the lead inserting into the roller. Therefore, in actual production, the gap is controlled within a certain range. However, in fast-paced production, operating conditions may vary, and the roller conveyor rubbing against the side guide can cause overload and shutdown. Therefore, by using the centering mechanism and the height adjustment mechanism to reasonably control the gap between the side guide body and the front roller conveyor, the problem of excessively large or small gaps in the prior art is avoided, and production efficiency is effectively improved.

[0040] Please see Figure 6 Furthermore, the adjusting screw 533 is a rod-shaped structure with external threads. One end of the adjusting screw 533 has a threaded blind hole for connecting with the positioning screw 531, and the other end is square.

[0041] Specifically, in this embodiment, there are multiple height adjustment components 53, which are evenly distributed circumferentially around the positioning hole 31. Preferably, there are three height adjustment components 53, which are evenly distributed circumferentially around the positioning hole 31. That is, the angle between each height adjustment component 53 is 120 degrees, and the three height adjustment components 53 can adjust the height from three directions.

[0042] Please see Figure 7In a preferred embodiment of the present invention, each height adjustment component 53 further includes a rotating wheel 55 connected to each adjusting screw 533 and a transmission belt 57 pulverizedly connected to each rotating wheel 55. Rotating one of the adjusting screws 533 causes the rotating wheel 55 mounted on that screw to rotate, and the transmission belt 57 drives each rotating wheel 55 to rotate simultaneously, thereby driving each adjusting screw 533 to rotate synchronously to achieve synchronous height adjustment. The height adjustment components 53 perform height adjustment synchronously from three directions, eliminating the need to adjust individual adjusting screws 533 and preventing inconsistencies in height adjustment among the various height adjustment components 53 that could cause the side guide body 3 to tilt.

[0043] Specifically, the rotating wheel 55 is a sprocket, and the transmission belt 57 is a chain. The chain simultaneously drives each of the sprockets to rotate, thereby simultaneously adjusting the adjusting screws 533. This eliminates the need to adjust each adjusting screw 533 individually, and the synchronous adjustment of each adjusting screw 533 maintains a consistent adjustment angle. Consequently, the rotation between the adjusting screw 533 and the positioning screw 531 is consistent, ensuring consistent height across all height adjustment components 53. This keeps the side guide body 3 horizontally positioned on the front cantilever 20. It should be noted that the chain is connected to other sprockets, which drive the chain in a cyclical motion, which in turn drives the rotating wheel 55. Alternatively, in other embodiments, the rotating wheel 55 can be a gear, and the transmission belt 57 can be a geared ring, with the gear and geared ring forming an internal mesh.

[0044] Furthermore, the sprocket is axially mounted on the square end of the adjusting screw 533. The sprocket rotates and drives the adjusting screw 533 to rotate. When one of the adjusting screws 533 is rotated, the sprocket mounted on the adjusting screw rotates. Through the chain and sprocket transmission, one of the sprockets can simultaneously drive the other two sprockets to rotate, thereby making the three adjusting screws rotate synchronously, thus realizing the synchronous adjustment of the height of the side guide body.

[0045] Please refer to the following: Figure 3 and Figure 4One of the centering components 70 is installed in one of the mounting slots 33. The centering component 70 includes a spring support 71 and an ejector 73 embedded in the mounting slot 33, and a pressure plate 75 covering the spring support 71 and the ejector 73. The spring support 71 radially supports the ejector 73 to move in the axial direction of the positioning post 1 to position the positioning post 1 from multiple directions. In this way, the positioning post 1 can remain coaxial with respect to the positioning hole 31, so that the positioning post 1 is centered with respect to the positioning hole 31. The positioning post 1 is vertically fixed to the front cantilever 20, so that the side guide body 3 always remains horizontal with respect to the front cantilever 20.

[0046] Specifically, in this embodiment, there are three centering components 70, which are circumferentially distributed around the positioning post 1, i.e., the centering components are spaced 120 degrees apart. The three centering components press against the positioning post 1 from three directions, thereby keeping the positioning post 1 vertical. In this way, the positioning hole 31 of the side guide body relative to the guide post is always coaxial with the positioning post 1.

[0047] Specifically, in this embodiment, the elastic support 71 is a spring. The preload of the spring supports the ejector 73 to move towards the positioning post 1, thereby adjusting the position of the positioning post 1 and the positioning hole 31 to achieve alignment. It should be noted that the springs can also be two or three arranged side by side in the height direction, and the number of springs can be set according to the depth of the mounting groove 33.

[0048] Please see Figure 8 The ejector 73 has a T-shaped cross-section and includes a base plate 733 and a top plate 731 connected to the base plate 733. The top plate 731 is in close contact with the elastic support 71. Under the action of the elastic support 71, the top plate 731 extends out of the mounting groove 33 and contacts the positioning post 1. The three top plates 731 act simultaneously on the outer periphery of the positioning post 1, making the positioning post 1 coaxial with the positioning hole 31. In this way, the side guide body 3 is always in a horizontal state relative to the front cantilever 20, so as to ensure the positional relationship with the front roller conveyor 30.

[0049] Furthermore, the pressure plate 75 is square, and the side guide body 3 has a groove for assembling the pressure plate 75. The pressure plate 75 covers the ejector 73 and the elastic support 71 and is fixed to the side guide body 3 by screws.

[0050] The side guide device 10 of the front roller conveyor of the crimping machine provided by the present invention radially supports the positioning column 1 through a plurality of centering components, so that the positioning hole 31 and the positioning column 1 are coaxially arranged. The side guide body 3 is always horizontal relative to the front cantilever 20 at the bottom. In this way, when the side guide body 3 is leveled by the centering mechanism 7, the height of the side guide body 3 is adjusted by the height adjustment mechanism 5, so that the distance between the side guide body 3 and the front cantilever 20 is always a vertical distance. This effectively ensures the spacing distance between the side guide body 3 and the front roller conveyor 30, ensures the adjustment accuracy, and effectively avoids the problem of the side guide device 10 rubbing against the rotating front roller conveyor 30.

[0051] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
