The clamping arms are rotatably connected to the frame and are equipped with at least one pressure roller. The belt is sleeved on at least two of the pressure rollers. The clamping arms are used to rotate relative to the frame until the belt abuts against the outer peripheral wall of the drum. The device includes a guide, a movable member, and a support. The guide is rotatably sleeved on one of the clamping arms and the movable member, and can drive the movable member to move relative to the clamping arm. The guide is used to support and guide the strip steel to assist the strip steel in winding onto the drum. The support is connected to the clamping arm where the guide is located, and the movable member is movably sleeved on the support.

[0006] In some or more embodiments, the support member is rod-shaped and one end is rotatably connected to the arm. The rotation center lines of the support member relative to the arm, the rotation center lines of the guide member relative to the arm, and the rotation center lines of the moving member relative to the guide member are spaced apart from each other and all extend in the same direction.

[0007] In some or more embodiments, the support member is a screw rod with one end connected to the clamping arm, and the winding aid device further includes: At least two locking members are threaded to the screw and spaced apart along the axial direction of the screw. The movable member is located between two adjacent locking members and is movably sleeved on the support member along the axial direction of the support member.

[0008] In some or more embodiments, the winding aid device further includes: An elastic element is sleeved on the screw and has two ends in the telescopic direction. The two ends of the elastic element abut against the moving element and one of the locking elements, respectively.

[0009] In some or more embodiments, the movable member is rod-shaped and one end is movably sleeved on the support member, and the winding aid device further includes: A limiting member is threadedly connected to the other end of the moving member, and a guide member is rotatably sleeved between the two ends of the moving member.

[0010] In some or more embodiments, the winding aid device further includes: A gasket is fitted onto the movable part and its two ends abut against the limiting member and the guide member, respectively.

[0011] In some or more embodiments, the guide includes: The body is connected to the arm and has a close side near the drum and a guide side away from the drum. The guide side is used to guide the strip steel and has a support surface and a transition surface connected to the support surface. The guide portion is plate-shaped and is connected to both sides of the support surface, and both the guide portion and the transition surface extend and bend from the support surface to the drum.

[0012] In some or more embodiments, the frame includes a frame body and two swing arms spaced apart from the frame body, each swing arm being rotatably connected to one of the clamping arms, and the winding aid device further includes: Two hydraulic cylinders, each hydraulic cylinder having a clamping arm and a corresponding swing arm hinged to its two ends respectively, the hydraulic cylinders being used to extend and retract to drive the clamping arm to rotate relative to the corresponding swing arm.

[0013] In some or more embodiments, the hydraulic cylinder is a three-position hydraulic cylinder, and the winding aid further includes a plurality of displacement switches disposed on the arm, the plurality of displacement switches being spaced apart along the length direction of the hydraulic cylinder, and the displacement switches being used to detect the working stroke of the piston rod of the hydraulic cylinder.

[0014] In some or more embodiments, the winding aid device further includes: The hydraulic assembly is connected to the three-position hydraulic cylinder and is used to drive the piston rod to extend and retract.

[0015] The beneficial effects provided by one or more embodiments of this application are as follows: After the strip steel enters the coiler, one or two clamping arms rotatably connected to the frame in the coiling aid can rotate. Each clamping arm is equipped with at least one pressure roller, bringing the pressure roller of the clamping arm close to the coiler's drum. The belts fitted on at least two pressure rollers can move with the pressure rollers to abut against the outer peripheral wall of the drum. The belts can be tensioned and tightly clamped to a portion of the outer peripheral wall of the drum. When the strip steel moves to almost contact the drum, the strip steel end inserts into the space between the belt and the drum and is bent and wound around the outer peripheral wall of the drum by the belt. A guide member is rotatably fitted onto one clamping arm and a movable member, and can drive the movable member to move relative to the clamping arm. The guide member is used to support and guide the strip steel to assist in winding the strip steel onto the drum. The guide member can support and guide the strip steel, and its rotation relative to the clamping arm can also drive the movable member rotatably connected to the guide member to move. The support member is connected to the clamping arm where the guide member is located, and the movable member is movably fitted onto the support member. When the guide member rotates relative to the clamping arm, it can drive the movable member to move relative to the support member. The support and moving parts provide rigid support to the guide components, ensuring effective support and guidance for the strip steel. Simultaneously, the guide components possess a degree of self-adjusting capability. As the coiler drum rotates, the strip steel can wind itself onto the drum, allowing the winding aid to separate from the strip steel. This enables the clamp arm to rotate relative to the frame. The guide components, supporting the strip steel, automatically adapt and change their position relative to the clamp arm. Furthermore, the guide components maintain support relative to the strip steel until they are completely separated. This reduces the possibility of improper or unstable guide component positioning causing rubbing against the strip steel during clamp arm rotation, minimizing the impact on strip steel surface quality and improving overall strip steel quality. To a certain extent, this addresses the technical problem of suboptimal strip steel quality. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that all directional indications in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. In this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] In related technologies, the guide component connected to the clamp in the coiling aid equipment can contact the strip steel and guide it to be wound onto the coiler drum. However, if a drive mechanism is used to adjust the position of the guide component, it is difficult to adjust it to the correct position, and it may scrape against the strip steel. For structures with elastic elements on the guide component, insufficient controllability of the elastic elements may also lead to instability of the guide component, resulting in scraping against the strip steel and affecting the quality of the strip steel, thus causing a technical problem of unsatisfactory strip steel quality. The embodiments of this application provide a coiling aid equipment that can at least partially solve the above-mentioned technical problems.

[0029] The present application will now be described in conjunction with the accompanying drawings: Figure 1 This application shows a schematic diagram illustrating the usage state of a roll-writing aid device in some or certain embodiments. Figure 2 This illustration shows a schematic diagram of the engagement state between a winding aid device and a winding drum in some or certain embodiments of this application. Figure 3 This application shows Figure 2 Side view of the winding machine and the winding drum, for reference. Figures 1-3 This application provides a winding aid device for assisting the winding of strip steel 200 onto the drum 100 of a coiler, comprising: Rack 1.

[0030] The belt 2 and two clamping arms 3 are rotatably connected to the frame 1 and are provided with at least one pressure roller 301. The belt 2 is sleeved on at least two pressure rollers 301. The clamping arms 3 are used to rotate relative to the frame 1 until the belt 2 abuts against the outer peripheral wall of the drum 100.

[0031] The guide 4, the movable part 5, and the support 6 are provided. The guide 4 is rotatably sleeved on a clamping arm 3 and the movable part 5, and can drive the movable part 5 to move relative to the clamping arm 3. The guide 4 is used to support the guide strip 200 to assist the strip 200 in winding to the drum 100. The support 6 is connected to the clamping arm 3 where the guide 4 is located, and the movable part 5 is movably sleeved on the support 6.

[0032] After the strip 200 enters the coiler, one or two clamping arms 3 rotatably connected to the frame 1 in the coiling aid can rotate. Each clamping arm 3 is equipped with at least one pressure roller 301, bringing the pressure roller 301 of the clamping arm 3 close to the coiler drum 100. The belt 2, which is sleeved on at least two pressure rollers 301, can move with the pressure rollers 301 to abut against the outer peripheral wall of the drum 100. The belt 2 can be tensioned and tightly clamped to part of the outer peripheral wall of the drum 100. When the strip 200 moves to almost contact the drum 100, the end of the strip 200 is inserted into the space between the belt 2 and the drum 100, and is bent and wrapped around the outer peripheral wall of the drum 100 by the belt 2. The guide member 4 is rotatably sleeved on a clamping arm 3 and a movable member 5, and can drive the movable member 5 to move relative to the clamping arm 3. The guide member 4 is used to support and guide the strip steel 200 to assist the strip steel 200 in winding to the drum 100. The guide member 4 can support and guide the strip steel 200, and the rotation of the guide member 4 relative to the clamping arm 3 can also drive the movable member 5, which is rotatably connected to the guide member 4, to move. The support member 6 is connected to the clamping arm 3 where the guide member 4 is located, and the movable member 5 is movably sleeved on the support member 6. When the guide member 4 rotates relative to the clamping arm 3, it can drive the movable member 5 to move relative to the support member 6. The support component 6 and the moving component 5 provide rigid support to the guide component 4, ensuring the support and guidance effect on the strip 200. Simultaneously, the guide component 4 has a certain self-adjusting position capability. When the coiler drum 100 rotates, the strip 200 can automatically wind itself onto the drum 100, allowing the winding aid to separate from the strip 200. This allows the clamping arm 3 to rotate relative to the frame 1. The guide component 4, supporting the strip 200, can automatically adapt and change its position relative to the clamping arm 3. Furthermore, the guide component 4 can maintain its support relative to the strip 200 until it is completely separated from the strip 200. This reduces the possibility of the guide component 4 scraping against the strip 200 due to improper or unstable positioning when the clamping arm 3 rotates, reducing the impact on the surface quality of the strip 200 and improving its overall quality. This, to a certain extent, solves the technical problem of the strip 200's suboptimal quality.

[0033] It should be noted that the clamping arm 3 can rotate relative to the frame 1 until the belt 2 abuts against the outer peripheral wall of the drum 100, and the clamping arm 3 can also rotate relative to the frame 1 until the belt 2 separates from the drum 100. The pressure roller 301 can rotate relative to the clamping arm 3. For ease of understanding, in Figure 1 The image shows the coil 100 of the coiler and the strip 200.

[0034] In some or more embodiments, the support member 6 is rod-shaped and one end is rotatably connected to the arm 3. The rotation center lines of the support member 6 relative to the arm 3, the rotation center lines of the guide member 4 relative to the arm 3, and the rotation center lines of the moving member 5 relative to the guide member 4 are spaced apart from each other and all extend in the same direction.

[0035] The clamping arm 3, support member 6, guide member 4, and moving member 5 are configured as described in the previous section. The guide member 4 can rotate within a certain range relative to the clamping arm 3, ensuring overall support stability. This improves the positional adaptability of the guide member 4 and reduces the possibility of jamming, thus guaranteeing the support effect on the strip 200. During the process of the clamping arm 3 rotating relative to the frame 1 until the belt 2 abuts against the outer peripheral wall of the drum 100, or during the process of the clamping arm 3 rotating relative to the frame 1 until the belt 2 separates from the outer peripheral wall of the drum 100, the guide member 4 can adapt to the position of the strip 200, which helps reduce potential scraping between the guide member 4 and the strip 200.

[0036] It should be noted that the two rotating connections in this application can be achieved through shafts or bearings, such as between the support member 6 and the arm 3, the guide member 4 and the arm 3, and the moving member 5. The rotation center line of the support member 6 relative to the arm 3 can be the axis of the rotating shaft that enables the rotational connection between the support member 6 and the arm 3. The rotating shaft can also be a structure such as a pin 13 that is rotatably inserted into the arm 3, or the axis of the rotating hole in the support member 6 that is rotatably fitted onto the arm 3. The same applies to the rotation center lines of the guide member 4 relative to the arm 3 and the moving member 5 relative to the guide member 4.

[0037] In some or more embodiments, the support member 6 is a screw rod with one end connected to the clamping arm 3, and the winding aid device further includes: At least two locking elements 7 are threaded to the screw and spaced apart along the axial direction of the screw. A movable element 5 is located between two adjacent locking elements 7 and is movably sleeved on the support element 6 along the axial direction of the support element 6.

[0038] The movable part 5 is located between two adjacent locking parts 7. The locking parts 7 can limit the movable part 5 to a certain extent. The locking parts 7 are threadedly connected to the screw, and the position of the locking parts 7 on both sides of the movable part 5 can also be changed to change the movable range of the movable part 5. The adjustable position range of the movable part 5 and the guide part 4 can be adjusted according to the needs.

[0039] In some or more embodiments, the support member 6 may also be a screw, and one end of the support member 6 is rotatably connected to the clamping arm 3. The rotation center lines of the support member 6 relative to the clamping arm 3, the rotation center lines of the guide member 4 relative to the clamping arm 3, and the rotation center lines of the moving member 5 relative to the guide member 4 may also be parallel to each other. The support member 6 may also be provided with two spaced locking members 7, such as nuts, and the moving member 5 is movably fitted between the two nuts. This facilitates implementation and operation.

[0040] Figure 4 This illustration shows an assembly diagram of a movable component and a support component according to some or certain embodiments of this application. Figure 5 This application shows Figure 4 Side view of the moving part and the supporting part. Figure 6 This application shows Figure 4 Top view of the moving parts and support components, see reference. Figures 4-6 In some or more embodiments, the roll-up assist device further includes: The elastic element 8 is sleeved on the screw and has two ends in the telescopic direction. The two ends of the elastic element 8 respectively abut against the moving element 5 and a locking element 7.

[0041] The elastic element 8 can provide a certain damping effect on the moving element 5, so that the guide element 4 and the moving element 5 have a certain positional adaptability, while also improving the supporting and guiding effect of the guide element 4 on the strip 200.

[0042] In some or more embodiments, the elastic element 8 may be a spring or a rubber elastic element 8, etc., all of which can provide a certain degree of damping.

[0043] In some or more embodiments, the movable member 5 is rod-shaped and one end is movably sleeved on the support member 6, and the winding aid device further includes: The limiting member 9 is threadedly connected to the other end of the moving member 5, and the guide member 4 is rotatably sleeved between the two ends of the moving member 5.

[0044] One end of the movable part 5 is movably fitted with the support part 6, and the other end of the movable part 5 can provide installation space for the guide part 4. The limiting part 9 connected by threads on the movable part 5 can limit the guide part 4 and also facilitate the disassembly and assembly of the guide part 4.

[0045] In some or more embodiments, the roll-up aid device further includes: A gasket 10 is fitted onto the movable part 5, with its two ends abutting against the limiting part 9 and the guide part 4, respectively. This facilitates the rotation of the guide part 4 relative to the limiting part 9 and reduces wear on the guide part 4.

[0046] Figure 7 This application shows an assembly schematic diagram of a guide member in some or certain embodiments, with reference to... Figure 7In some or more embodiments, the guide 4 includes: The main body 401 is connected to the arm 3 and has a close side 4011 near the drum 100 and a guide side 4012 away from the drum 100. The guide side 4012 is used to support the guide strip 200. The guide side 4012 has a support surface 40121 and a transition surface 40122 connected to the support surface 40121.

[0047] The guide part 402 is plate-shaped and is connected to the two sides of the support surface 40121, respectively, with the transition surface 40122 and the guide part 402 and the transition surface 40122 extending and bending from the support surface 40121 toward the drum 100.

[0048] The proximal side 4011 of the main body 401 of the guide member 4 can be close to the drum 100 when the arm 3 rotates. The support surface 40121 of the guide side 4012 can support and guide the strip 200. The transition surface 40122 and the guide part 402 are respectively connected to the two sides of the support surface 40121, and both extend and bend from the support surface 40121 toward the drum 100. Thus, a certain curvature can be formed on both sides of the support surface 40121. When the arm 3 rotates and drives the guide member 4 to rotate relative to the strip 200, it is easy for the guide member 4 to rotate to support and guide the strip 200, or to completely separate from the strip 200.

[0049] It should be noted that the guide component 4 is usually provided with a surface that fits into the support strip 200.

[0050] In some or more embodiments, the frame 1 includes a frame body 101 and two swing arms 102 that are spaced apart from the frame body 101, each swing arm 102 being rotatably connected to a clamping arm 3. The winding aid device also includes: Two hydraulic cylinders 11 are provided, each with a hinged arm 3 and a corresponding swing arm 102 at both ends. The hydraulic cylinders 11 are used to extend and retract, driving the hinged arm 3 to rotate relative to the corresponding swing arm 102. This facilitates rotation control of the hinged arm 3 relative to the swing arm 102. When the hinged arm 3 rotates to a certain angle relative to the swing arm 102, the pressure roller 301 on the hinged arm 3 can press the belt 2 tightly against the outer peripheral wall of the drum 100. The hydraulic cylinders 11 can be used to adjust the range of rotation of the hinged arm 3 relative to the swing arm 102 to accommodate drums 100 with different diameters.

[0051] In some or more embodiments, one end of the swing arm 102 is connected to the frame 101, and the other end of the swing arm 102 is rotatably connected to one end of the clamping arm 3. The two ends of the hydraulic cylinder 11 can be hinged to the swing arm 102 and the clamping arm 3 respectively, and the rotation center line or axis between the swing arm 102 and the clamping arm 3 is spaced apart from the piston rod of the hydraulic cylinder 11. The guide member 4 and the support member 6 can both be located at the end of the clamping arm 3 away from the swing arm 102. The transition surface 40122 of the guide member 4 is located on the side of the support surface 40121 opposite to the swing arm 102, and the guide portion 402 is located on the side of the support surface 40121 closer to the swing arm 102.

[0052] In some or more embodiments, the hydraulic cylinder 11 is a three-position hydraulic cylinder 11, and the winding aid device also includes a plurality of displacement switches (not shown in the figure) disposed on the arm 3. The plurality of displacement switches are distributed at intervals along the length direction of the hydraulic cylinder 11, and the displacement switches are used to detect the working stroke of the piston rod of the hydraulic cylinder 11.

[0053] At different positions of the three-position hydraulic cylinder 11, the clamping arm 3 can be rotated relative to the swing arm 102 to adapt to the drum 100 with different diameters, which is convenient for operation and control. In addition, multiple displacement switches are set and distributed at intervals along the length of the hydraulic cylinder 11. The displacement switches are used to detect the piston stroke of the hydraulic cylinder 11, which can improve the accuracy of the hydraulic cylinder 11.

[0054] In some or more embodiments, three displacement switches may also be provided on the clamping arm 3, which can correspond to different working positions of the piston cylinder in the three-position hydraulic cylinder 11. The working stroke of the hydraulic cylinder 11 on the clamping arm 3 equipped with the guide 4 can also be greater than the working stroke of the hydraulic cylinder 11 on another clamping arm 3. This facilitates the control and switching of different working positions of the hydraulic cylinder 11. For example, it can be applied to drums with a diameter of 510mm or 610mm.

[0055] In some or more embodiments, the piston rods of the two hydraulic cylinders 11 have a diameter of 36 mm, and the cylinder diameters can be 63 mm / 56 mm. The working strokes of the two hydraulic cylinders 11 can be 20 mm / 40 mm and 20 mm / 30 mm, respectively. This facilitates manufacturing.

[0056] In some or more embodiments, the roll-up aid device further includes: The hydraulic assembly 12 is connected to the three-position hydraulic cylinder 11 and is used to drive the piston rod to extend and retract. This facilitates the operation and control of the three-position hydraulic cylinder 11.

[0057] In some or more embodiments, Figure 8The diagram illustrates the structure of a hydraulic assembly in some or all embodiments of this application. The hydraulic assembly 12 may include a fluid supply container (not shown), a three-position four-way solenoid valve 1201, a pilot-operated check valve 1202, a one-way throttle valve 1203, and a pressure reducing valve 1204. The fluid in the supply container flows through the three-position four-way solenoid valve 1201 into the hydraulic cylinder 11. Changing the operating position of the three-position four-way solenoid valve 1201 allows the fluid to pass through it and enter different piston chambers of the hydraulic cylinder 11, thereby changing the operating position of the hydraulic cylinder 11. A pilot-operated check valve 1202, a one-way throttle valve 1203, and a pressure reducing valve 1204 may also be provided between the three-position four-way solenoid valve 1201 and the hydraulic cylinder 11 to improve the safety of the hydraulic assembly 12.

[0058] It should be noted that, Figure 8 The middle part is a hydraulic assembly 12 that drives a three-position hydraulic cylinder 11.
