Abstract
Description
Technical Field
[0001] This application belongs to the field of strip coil feeding technology, specifically relating to a feeding structure for strip coils. Background Technology
[0002] A strip coil is a rolled material formed by winding a strip of continuous length and fixed width onto a core using a coiler. During use, the strip coil is usually mounted on a shaft above the ground so that it is lifted off the ground during rotational feeding, thus avoiding surface damage to the strip due to friction.
[0003] Currently, the loading of strip coils is mostly done manually. Operators need to align the core of the strip coil with the spool and push it axially until the spool inserts into the core. However, when loading high-quality or thick strip coils, obstructed vision can cause the core and spool to misalign, preventing the spool from inserting smoothly. This not only reduces loading efficiency but can also cause dents on the end face of the strip coil due to impact, affecting the quality of the material in subsequent use. Utility Model Content
[0004] This application provides a feeding structure for strip coils, which aims to reduce manpower consumption, ensure efficient feeding of strip coils, and avoid collision between the rotating shaft and the end face of the strip coil.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] A feeding structure for strip coils is provided, including a rotating shaft for inserting a coil core; and further including:
[0007] A fixed plate; the rotating shaft is disposed on the fixed plate, and one end is located on the front side of the fixed plate; the front side of the fixed plate also has a positioning part, which is located below the rotating shaft, has a degree of freedom to move relative to the fixed plate in the vertical direction, and is connected to a height adjustment mechanism;
[0008] A support member, disposed on the front side of the positioning part, is used to support the strip roll and ensure that the core axis is parallel to the rotating shaft; the support member is connected to the fixing plate via a guide structure, forming a degree of freedom to move relative to the positioning part in the front-back direction, and can rise and fall synchronously with the positioning part; and
[0009] A limiting component is disposed on the support member for engaging with the strip roll to restrict the horizontal movement of the strip roll relative to the support member, and to ensure that the core is coaxial with the shaft when the limiting component engages with the strip roll.
[0010] In one possible implementation, the support member includes:
[0011] A base plate, disposed on the front side of the positioning part, has its upper side used to support the roll material; and
[0012] A side plate is provided on the side of the base plate facing away from the positioning part, and the side of the side plate facing the positioning part is used to abut against the end face of the roll material so that the core axis is parallel to the rotating shaft;
[0013] The base plate or the side plate is connected to the fixing plate through the guide structure.
[0014] In one possible implementation, the side plate has a first strip-shaped hole extending through the front-rear direction, and the first strip-shaped hole extends in the vertical direction; the limiting component includes:
[0015] A guide cylinder, fitted into the first strip-shaped hole, has its axis parallel to the front-to-back direction and has the freedom to move relative to the side plate in the up-down direction; and
[0016] A limiting rod is slidably inserted into the guide cylinder; the limiting rod is used to insert into the core, forming a line contact or surface contact between the limiting rod and the inner wall of the core.
[0017] The guide cylinder has a return spring sleeved on the outer periphery of the limiting rod. The two ends of the return spring are respectively connected to the front end of the limiting rod and the guide cylinder to drive the limiting rod to move forward relative to the guide cylinder.
[0018] Furthermore, the rear end of the limiting rod has an anti-detachment portion extending radially outward; the return spring is used to drive the limiting rod to move until the anti-detachment portion abuts against the guide cylinder, thereby preventing the limiting rod from detaching from the guide cylinder.
[0019] In one possible implementation, the guiding structure includes:
[0020] A pre-drilled hole is provided on the support member, and its axial direction is parallel to the front-rear direction; and
[0021] A guide rod is fixedly mounted on the positioning part and slidably inserted into the reserved hole, so that the support member has a degree of freedom to move relative to the positioning part in the front-back direction;
[0022] The guide rod end can extend out from the front end of the reserved hole, and the extended part has a limiting disc extending outward in a radial direction;
[0023] The limiting plate is used to abut against the side of the support member facing away from the positioning part, so as to prevent the support member from disengaging from the guide rod.
[0024] In one possible implementation, the height adjustment mechanism includes:
[0025] A first nut is fixedly mounted on the positioning part, and its axial direction is parallel to the vertical direction; and
[0026] A first screw, threadedly connected to the first nut, has an outwardly extending portion at its lower end that extends radially outward and is used for support on the ground.
[0027] In one possible implementation, the support member has a height leveling mechanism for supporting itself on the ground, the height leveling mechanism comprising:
[0028] The second nut is fixedly mounted on the support member, and its axial direction is parallel to the vertical direction; and
[0029] The second screw is threaded onto the second nut, and its lower end face has a concave ball groove, in which a ball is embedded; the ball extends to the lower side of the second screw to support it on the ground, and rolls synchronously with the movement of the support.
[0030] In one possible implementation, the fixing plate has a second strip-shaped hole extending through the front-rear direction, and the second strip-shaped hole extends in the vertical direction; the rotating shaft further includes:
[0031] The lifting component is slidably disposed on the rear side of the fixed plate in the vertical direction and is connected to a lifting drive component.
[0032] The rotating shaft is rotatably mounted on the lifting member and inserted into the second strip-shaped hole, forming a degree of freedom to move relative to the fixed plate in the vertical direction.
[0033] In one possible implementation, the lifting drive component includes:
[0034] The third nut is fixedly installed on the lifting component, and its axial direction is parallel to the vertical direction;
[0035] The third screw is rotatably mounted above the lifting member and threadedly connected to the third nut; and
[0036] A rotating motor is fixedly installed above the lifting component, and its power output axis is perpendicular to the axis of the third screw.
[0037] The upper end of the third screw adopts a worm gear structure, and the power output end of the rotating motor has a worm wheel that meshes with the worm gear structure.
[0038] In one possible implementation, the rotating shaft adopts an air-expanding roller structure;
[0039] The lifting component is equipped with a pneumatic disc brake, which is connected to the rotating shaft to apply pressure to the air roller, so that the outer peripheral wall of the air roller and the inner wall of the core form surface contact or multi-point contact.
[0040] In one possible implementation, a guide rail extending in the vertical direction is fixedly provided on the front side of the fixing plate;
[0041] The front side of the guide rail is provided with a guide groove extending in the vertical direction, and the positioning part has a docking block that is slidably embedded in the guide groove so that the positioning part and the guide rail can slide together.
[0042] The guide groove extends through the upper end face of the guide rail, and a cover can be detachably connected to the upper end of the guide rail; the cover is used to abut against the docking block to prevent the positioning part from disengaging from the guide rail.
[0043] In this embodiment, the strip roll can be supported by the support member so that the core axis is parallel to the horizontal plane; at this time, adjusting the orientation of the strip roll can make the core axis and the shaft axis parallel; based on this, the height of the positioning part can be controlled by adjusting the height adjustment mechanism. Since the support member and the positioning part are connected by the guide structure, the height control of the positioning part can be reflected on the support member, so that when the core axis and the shaft axis are parallel, the core center axis and the shaft center axis are on the same horizontal plane.
[0044] Subsequently, by connecting the limiting component to the strip roll, the position of the strip roll relative to the support can be fixed, thereby making the core and the shaft coaxial.
[0045] Finally, push the support towards the fixed plate to insert the spool into the core. Since the core and spool are already aligned, the spool will not collide with the end face of the strip roll during insertion, thus ensuring efficient feeding of the strip roll while avoiding damage to the end face of the strip roll.
[0046] During the sequential feeding and use of the same batch of strip coils, the height adjustment mechanism can be pre-adjusted so that when each strip coil in the batch is placed on the support, the central axis of the coil core and the central axis of the rotating shaft are on the same horizontal plane, so as to facilitate the rapid execution of the aforementioned operation steps.
[0047] The strip coil feeding structure provided in this embodiment, compared with the prior art, can reduce the manpower consumption in the strip coil feeding stage, ensure that the strip coil can be fed efficiently, avoid collision between the rotating shaft and the end face of the strip coil, improve the working efficiency of the strip coil feeding process, and effectively guarantee the subsequent use quality of the strip coil.

Therefore, they should not be construed as limitations on this application.
[0065] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0066] Please refer to the following: Figures 1 to 12The feeding structure for strip coils provided in this application will now be described. The feeding structure for strip coils proposed in this application includes a rotating shaft 1, a fixing plate 2, a support member 3, and a limiting assembly 4.
[0067] The rotating shaft 1 is mounted on the fixing plate 2 and is used to insert one end of the self-contained material roll into the core. The end of the rotating shaft 1 into the core is located on one side of the thickness direction of the fixing plate 2. In this embodiment, for ease of description, this side is defined as the front side of the fixing plate 2.
[0068] In practical use, based on the fit between the rotating shaft 1 and the inner cavity of the core, there are two different situations:
[0069] 1. The rotating shaft 1 and the inner cavity of the core are interference-fitted. When the rotating shaft 1 is inserted into the core, it can rotate synchronously with the traction of the strip on the surface of the core. At this time, the rotating shaft 1 and the fixing plate 2 are rotatably connected.
[0070] 2. There is a gap between the rotating shaft 1 and the inner cavity of the core, that is, the two are in line contact or point contact. At this time, the core can rotate relative to the rotating shaft 1, that is, the strip roll is unloaded. At this time, the rotating shaft 1 and the fixing plate 2 are in a fixed connection relationship.
[0071] The above two situations only apply to the case where the core adopts a conventional design, that is, the strip is wound around the outer circumference of the core, and the core does not have the ability to rotate relative to the strip. In some special cases, the core adopts a combination structure of inner core and outer core, that is, the outer core is placed around the outer circumference of the inner core and can rotate relative to the inner core. In this case, the fit between the rotating shaft 1 and the inner core must be an interference fit so that when the strip is unloaded, the inner core is fixed and the outer core rotates to achieve the purpose of feeding.
[0072] Typically, the fixing plate 2 is the side panel of the relevant equipment, that is, a vertically extending plane of the area to be loaded. The front side of the fixing plate 2 also has a positioning part 21, which is located below the rotating shaft 1 and has the freedom to move relative to the fixing plate 2 in the vertical direction; in order to lock the positioning part 21 in the vertical direction, the positioning part 21 is also connected to a height adjustment mechanism 5.
[0073] The support member 3 is located on the front side of the positioning part 21 to support the strip roll and make the core axis parallel to the rotating shaft 1. Furthermore, the support member 3 is connected to the fixing plate 2 through the guide structure 6 so that the support member 3 has the freedom to move relative to the positioning part 21 in the front-back direction. The support member 3 can also rise and fall synchronously with the positioning part 21 so as to change the initial height of the support surface provided by the support member 3 through the height adjustment mechanism 5.
[0074] The limiting component 4 is disposed on the support member 3 and is used to connect with the strip roll to limit the movement of the strip roll relative to the support member 3 in the horizontal direction. When the initial height of the support surface provided by the support member 3 is adapted to the actual size of the strip roll, the core can be coaxially set with the shaft 1 by connecting the limiting component 4 with the strip roll.
[0075] In this embodiment, the support member 3 can support the strip roll so that the core axis is parallel to the horizontal plane. At this time, adjusting the orientation of the strip roll can make the core axis parallel to the axis of the rotating shaft 1. Based on this, the height of the positioning part 21 can be controlled by adjusting the height adjustment mechanism 5. Since the support member 3 and the positioning part 21 are connected by the guide structure 6, the height control of the positioning part 21 can be reflected on the support member 3 so that when the core axis is parallel to the axis of the rotating shaft 1, the central axis of the core and the central axis of the rotating shaft 1 are on the same horizontal plane.
[0076] Subsequently, by connecting the limiting component 4 to the strip roll, the position of the strip roll relative to the support 3 can be fixed, thereby making the core and the rotating shaft 1 coaxial.
[0077] Finally, push the support 3 toward the fixing plate 2 so that the rotating shaft 1 can be inserted into the core. Since the core and the rotating shaft 1 have been aligned at this time, the process of the rotating shaft 1 inserting into the core will not collide with the end face of the strip roll, thus ensuring efficient feeding of the strip roll while avoiding damage to the end face of the strip roll.
[0078] During the sequential feeding and use of the same batch of strip coils, the height adjustment mechanism 5 can be pre-adjusted so that when each strip coil in the batch is placed on the support 3, the core center axis and the center axis of the rotating shaft 1 are on the same horizontal plane, so as to facilitate the rapid execution of the aforementioned operation steps.
[0079] The strip coil feeding structure provided in this embodiment, compared with the prior art, can reduce the manpower consumption in the strip coil feeding stage, ensure that the strip coil can be fed efficiently, and avoid collision between the rotating shaft 1 and the end face of the strip coil, thereby improving the working efficiency of the strip coil feeding process and effectively ensuring the subsequent use quality of the strip coil.
[0080] In some embodiments, such as Figure 1 and Figure 5 As shown, the support member 3 includes a base plate 31 and a side plate 32.
[0081] The base plate 31 is located on the front side of the positioning part 21, and its upper side is used to support the roll material.
[0082] The side plate 32 is disposed on the side of the base plate 31 facing away from the positioning part 21, and the side plate 32 facing the positioning part 21 is used to abut the end face of the roll material so that the core axis is parallel to the rotating shaft 1.
[0083] The base plate 31 or the side plate 32 is connected to the fixed plate 2 through the guide structure 6; in this embodiment, the base plate 31 is connected to the fixed plate 2 through the guide structure 6.
[0084] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the side plate 32 has a first strip hole 321 that runs through the front and rear directions and extends in the vertical direction; based on this, the limiting assembly 4 includes a guide cylinder 41 and a limiting rod 42.
[0085] The guide cylinder 41 is fitted into the first strip hole 321, its axis is parallel to the front and back direction, and it has the degree of freedom to move relative to the side plate 32 in the up and down direction. In this embodiment, both the front and rear ends of the guide cylinder 41 have radially outward extending stop discs. The two stop discs abut against the front and rear sides of the side plate 32 respectively to restrict the movement of the guide cylinder 41 relative to the side plate 32 in its own axis.
[0086] The limiting rod 42 is slidably inserted into the guide cylinder 41, with one end extending to the front of the guide cylinder 41 and having a handle for the operator to grip. By moving the guide cylinder 41 longitudinally and simultaneously adjusting the position of the strip roll on the base plate 31, the limiting rod 42 can be inserted into the roll core to form line or surface contact between the limiting rod 42 and the inner wall of the roll core. At this time, the roll core can be fixed by friction damping.
[0087] It should be noted that, based on the side plate 32 restricting the forward movement of the strip roll and the bottom plate 31 supporting the strip roll, the limiting rod 42 can effectively limit the radial movement range of the core, that is, prevent the core from dislodging from the limiting rod 42; at the same time, since the upper side of the bottom plate 31 is a horizontal plane, the backward movement of the strip roll can be prevented by limiting the backward movement of the strip roll through friction damping.
[0088] The front side of the guide cylinder 41 has a return spring 421 sleeved on the outer periphery of the limiting rod 42. The two ends of the return spring 421 are respectively connected to the front end of the limiting rod 42 and the guide cylinder 41 to drive the limiting rod 42 to move forward relative to the guide cylinder 41.
[0089] The rear end of the limiting rod 42 has an anti-detachment part 422 extending radially outward; the return spring 421 is used to drive the limiting rod 42 to move to the anti-detachment part 422 abutting against the guide cylinder 41, so as to limit the limiting rod 42 from disengaging from the guide cylinder 41, and at the same time, it can prevent the limiting rod 42 from abutting against the outer wall of the strip roll, thus affecting the contact between the strip roll and the side plate 32, as well as the positioning of the strip roll relative to the limiting rod 42.
[0090] In some embodiments, such as Figure 1 , Figure 5and Figure 6 As shown, the guide structure 6 includes a reserved hole 61 and a guide rod 62.
[0091] The reserved hole 61 is opened on the support member 3, specifically on the base plate 31, and the axial direction of the reserved hole 61 is parallel to the front and rear direction.
[0092] The guide rod 62 is fixedly mounted on the positioning part 21 and slidably inserted into the reserved hole 61, so that the support member 3 has the freedom to move relative to the positioning part 21 in the front-back direction.
[0093] After the structure is assembled, the end of the guide rod 62 can extend out from the front end of the reserved hole 61, and the extended part has a limiting plate 621 extending outward in the radial direction; the limiting plate 621 is used to abut against the side of the support member 3 facing away from the positioning part 21, so as to restrict the support member 3 from disengaging from the guide rod 62.
[0094] In some embodiments, as shown in the figure Figure 1 and Figure 8 As shown, the height adjustment mechanism 5 includes a first nut 51 and a first screw 52.
[0095] The first nut 51 is fixedly mounted on the positioning part 21, and its axial direction is parallel to the vertical direction.
[0096] The first screw 52 is threaded onto the first nut 51, and its lower end has an outwardly extending portion 521 that extends radially outward, and the outwardly extending portion 521 is used to support the ground; compared to the method of directly contacting the lower end of the first screw 52 with the ground, the outwardly extending portion 521 can increase the contact area to ensure the stability of the mechanism.
[0097] In some embodiments, such as Figure 1 and Figure 7 As shown, the support member 3 has a height leveling mechanism 7 for supporting on the ground. The height leveling mechanism 7 includes a second nut 71 and a second screw 72.
[0098] The second nut 71 is fixedly mounted on the support member 3, and its axial direction is parallel to the vertical direction.
[0099] The second screw 72 is threaded onto the second nut 71. A concave ball groove 721 is provided on its lower end face, and a ball 722 is embedded in the concave ball groove 721. The ball 722 extends to the lower side of the second screw 72 to support it on the ground and rolls synchronously with the movement of the support member 3.
[0100] In some embodiments, such as Figure 1 and Figure 11 As shown, the fixed plate 2 has a second strip hole 22 that runs through the front and rear directions and extends in the vertical direction; based on this, the rotating shaft 1 also includes a lifting member 11.
[0101] The lifting component 11 is slidably disposed on the rear side of the fixed plate 2 in the vertical direction, and is connected to a lifting drive component 8 for driving the lifting component 11 to move.
[0102] The rotating shaft 1 is rotatably mounted on the lifting member 11; after the lifting member 11 and the fixed plate 2 are combined, the rotating shaft 1 passes through the second strip hole 22 and extends to the front side of the fixed plate 2, so that the rotating shaft 1 forms a degree of freedom to move relative to the fixed plate 2 in the up and down direction.
[0103] In some embodiments, such as Figure 2 , Figure 11 and Figure 12 As shown, the lifting drive component 8 includes a third nut 81, a third screw 82, and a rotating motor 83.
[0104] The third nut 81 is fixedly mounted on the lifting component 11, and its axial direction is parallel to the vertical direction.
[0105] The third screw 82 is rotatably mounted above the lifting component 11 and is threadedly connected to the third nut 81.
[0106] The rotating motor 83 is fixedly mounted above the lifting component 11, specifically on a protruding plate above the lifting component 11, and the power output axis of the rotating motor 83 is perpendicular to the axis of the third screw 82.
[0107] In order to realize the transmission between the rotating motor 83 and the third screw 82, the upper end of the third screw 82 adopts a worm gear structure 821, and the power output end of the rotating motor 83 has a worm wheel 831 that meshes with the worm gear structure 821.
[0108] In some embodiments, such as Figure 2 and Figure 11 As shown, the rotating shaft 1 adopts an air expansion roller structure; it should be noted that the air expansion roller structure mentioned here is a roller structure that controls the expansion and contraction of its surface by inflating and deflating air, thereby making it convenient and quick to fix and replace the core.
[0109] The lifting component 11 is equipped with a pneumatic disc brake 10, which is connected to the rotating shaft 1 to pressurize the air roller so that the outer peripheral wall of the air roller and the inner wall of the core form a surface contact or multi-point contact.
[0110] In some embodiments, such as Figure 1 , Figure 9 and Figure 10 As shown, a guide rail 9 extending in the vertical direction is fixedly installed on the front side of the fixed plate 2; a guide groove 91 extending in the vertical direction is opened on the front side of the guide rail 9, and a docking block 211 is slidably embedded in the guide groove 91 on the positioning part 21 so that the positioning part 21 and the guide rail 9 slide together.
[0111] The guide groove 91 passes through the upper end face of the guide rail 9, and a cover 92 can be detachably connected to the upper end of the guide rail 9; the cover 92 is used to abut against the docking block 211 to prevent the positioning part 21 from disengaging from the guide rail 9.
[0112] It should be further explained that the detachable connection structure of the guide rail 9 and the cover 92 includes a strip-shaped perforation and a convex rib rotatably connected to the upper end of the guide rail 9; the upper end of the convex rib has a snap-fit strip extending radially outward, the combination structure of the snap-fit strip and the convex rib can pass through the perforation, and the convex rib can rotate to abut against the upper end face of the cover 92.
