Description

Technical Field

[0001] This application relates to the field of wrapping technology, and in particular to a rotary wire coil packaging reel and wrapping device. Background Technology

[0002] Spring steel wire is a type of steel wire used to make springs or wire profiles. Depending on the application of the spring, various types of spring steel wire are required. The process of making spring steel wire from raw steel wire involves winding and packaging the wire to reduce friction. In the field of spring steel wire packaging, traditional packaging methods mainly rely on manual operation or simple mechanical auxiliary equipment. Currently, there is a lack of comprehensive winding and packaging devices on the market for large-mass, large-inner-diameter spring steel wires.

[0003] To address the aforementioned issues, the existing technology CN105217070B can achieve full wrapping and packaging. However, in this technical solution, the stretch film placement rack is located close to the inside of the C-shaped turntable, which results in the C-shaped turntable being able to accommodate a relatively small wire roll. Larger rolls of stretch film cannot be used either. When the wire roll is large, it will collide with the stretch film placement rack, making packaging impossible.

[0004] The existing technology CN217456442U uses a film roll that is directly placed on the outside of a C-shaped rotating plate and wound directly onto a wire roll. It can accommodate film rolls with larger inner diameters and spring steel wire rolls with larger ring widths. However, because the film is wound directly from the film roll onto the wire roll, gaps and skewing occur in the film during the high-speed rotation of the C-shaped rotating plate due to the uneven surface of the wire roll. Furthermore, when the center of gravity of the spring steel wire roll is not concentric with the center of the C-shaped plate, the free winding length of the film roll is too long. When the C-shaped plate rotates close to the spring steel wire roll, the film will loosen, resulting in twisting and tangling. Existing wrapping and packaging equipment cannot adapt to different specifications of packaging materials. Therefore, when using existing wrapping and packaging devices to package spring steel wire, the adaptability is poor and the packaging effect is unsatisfactory. Utility Model Content

[0005] In order to adapt to spring steel wire coils with larger ring widths and achieve better packaging results, this application provides a rotary wire coil packaging reel and a winding and packaging device.

[0006] The rotary wire reel packaging device provided in this application adopts the following technical solution:

[0007] A rotary wire coil packaging reel includes an annular rotating plate with a notch through which a spring steel wire coil can be inserted. A winding roller is mounted on the annular rotating plate for holding packaging paper. The winding roller is located on the outer side of the annular rotating plate away from its center. Several steel bars are mounted on the annular rotating plate, spaced around the circumference of the annular rotating plate. The steel bars are positioned on the inner side of the annular rotating plate, closer to the center than the winding roller. The packaging paper can be wound around all the steel bars sequentially onto the spring steel wire coil.

[0008] By adopting the above technical solution, the roller is set on the outer side of the annular rotating plate away from the center, which can install large rolls of packaging paper and is compatible with spring steel wire rolls with a larger ring width, making it more adaptable.

[0009] During the high-speed rotation of the annular plate, when the center of gravity of the spring steel wire coil is not concentric with the center of the annular plate, the free winding length of the paper roll and film roll is too long. The placement of the steel rods close to the inner side of the center of the annular plate shortens the free winding length of the film roll and paper roll, reduces the twisting and tangling of the film and packaging paper, and the packaging passes around several steel rods in sequence, so that the annular plate maintains stable traction force during the packaging and winding of the non-smooth steel wire coil.

[0010] Optionally, the annular rotating plate is provided with a plurality of counterweight plates, and the plurality of counterweight plates are equidistantly arranged along the contour direction of the annular rotating plate.

[0011] By adopting the above technical solution, the counterweight plate can balance the eccentric force when the annular rotating plate rotates, thereby improving the stability of the annular rotating plate.

[0012] Optionally, multiple rollers are provided, and each roller corresponds to a counterweight plate, with the rollers mounted on the corresponding counterweight plates.

[0013] By adopting the above technical solution, the rollers are set on the outside of the counterweight plate to save assembly space, and larger rolls of packaging paper can be assembled. The setting of multiple rollers can realize the simultaneous feeding of multiple rolls of packaging paper, thereby improving packaging efficiency.

[0014] Optionally, the steel bars are divided into several groups, with each group containing at least three steel bars, and a group of steel bars is provided between every two adjacent counterweight plates.

[0015] By adopting the above technical solution, the design of the steel rods optimizes the guiding path of the packaging paper, ensuring uniform winding tension. When the annular rotating plate rotates at high speed, the three steel rods can prevent the lighter film from flying out due to excessive rotation speed.

[0016] Optionally, the annular rotating plate is provided with a first guide groove and a second guide groove. The first guide groove is provided on the back of the annular rotating plate along the outline of the annular rotating plate, and the second guide groove is provided along the outer side wall of the annular rotating plate.

[0017] By adopting the above technical solution, two guide grooves are opened to make the rotation of the annular rotating plate more stable, and at the same time, it is easier to coordinate with other drive components for positioning, thereby improving assembly accuracy.

[0018] The wrapping and packaging device provided in this application adopts the following technical solution:

[0019] A winding and packaging device, employing the aforementioned rotary wire coil packaging reel, includes a worktable, a first drive assembly, a second drive assembly, and a feeding assembly. The rotary wire coil packaging reel is vertically mounted on the first drive assembly. The first drive assembly controls the rotation of the annular rotating plate along its central axis. The second drive assembly drives the first drive assembly and the annular rotating plate towards the feeding assembly, allowing spring steel wire to extend into the annular rotating plate through a notch. The feeding assembly supports a horizontally placed spring steel wire coil, enabling the spring steel wire coil to rotate around the central axis of the worktable.

[0020] By adopting the above technical solution, the hook lifts the spring steel wire coil and places it horizontally on the feeding assembly. The second drive assembly drives the first drive assembly and the rotary wire coil packaging disc forward until the spring steel wire coil passes through the notch and extends into the annular rotating plate. Then, the first drive assembly drives the annular rotating plate to rotate and wind in the vertical direction, realizing automated packaging.

[0021] Optionally, the first drive assembly includes a movable base and a first motor. The annular rotating plate is rotatably connected to the movable base. The movable base is provided with a plurality of guide wheels, which are arranged around the central axis of the annular rotating plate and abut against the outer circumferential surface of the annular rotating plate. The first motor is used to drive at least one of the guide wheels to rotate, so that the guide wheel drives the annular rotating plate to rotate.

[0022] By adopting the above technical solution, the first drive component ensures that the annular rotating plate can rotate stably along the central axis in the vertical direction when applied to the packaging and wrapping device, and the guide wheel has a simple design structure and is easy to maintain.

[0023] Optionally, the second drive assembly includes a track seat and a mounting platform. A hydraulic cylinder is provided on the mounting platform and is connected to the movable seat. The movable seat is slidably disposed on the track seat, and the track seat is disposed toward the feeding assembly.

[0024] By adopting the above technical solution, the spring steel wire coil is inserted into the annular rotating plate, achieving precise positioning of the annular rotating plate and adapting to steel wire coils of different sizes.

[0025] Optionally, the feeding mechanism includes multiple motor bases, which are distributed in a circular pattern at equal intervals around the central axis of the worktable. A second motor is provided at the bottom of each motor base, and a drive roller is provided on the motor base. The drive roller is placed horizontally, and its central axis intersects with the central axis of the worktable. The second motor drives the drive roller to roll. A limit post is provided at the top of the motor base, and the limit post is located at the end of the drive roller near the center of the circle.

[0026] By adopting the above technical solution, the active roller and the limiting post work together to clamp the wire coil, ensuring that there is no deviation during rotation.

[0027] Optionally, a first support roller is provided on the motor base. The first support roller is horizontally positioned and faces the center of the worktable. The central axis of the first support roller intersects the central axis of the worktable. A support seat is provided between two adjacent motor bases. A second support roller is provided on the support seat. The central axis of the second support roller intersects the central axis of the worktable. The central axes of the first support roller, the second support roller, and the drive roller all intersect at a point on the central axis of the worktable.

[0028] By adopting the above technical solution, a multi-point support structure is formed, which enhances the support force and rotational stability of the wire coil. The central axes of the active roller, the first support roller and the second support roller intersect at one point, reducing resistance and making the rotational transmission of the spring wire coil smoother.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The winding roller is located on the outer side of the annular rotating plate away from the center, which can accommodate large rolls of packaging paper and is suitable for spring steel wire rolls with a larger ring width, making it more adaptable.

[0031] 2. When the centroid of the spring steel wire coil is not concentric with the center of the annular rotating plate during high-speed rotation, the free winding length of the paper roll and film roll is too long. The placement of the steel rod close to the inner side of the center of the annular rotating plate shortens the free winding length of the film roll and paper roll, reduces the twisting and tangling of the film and packaging paper, and the packaging passes around several steel rods in sequence, so that the annular rotating plate maintains stable traction force during the packaging and winding of the non-smooth steel wire coil.

[0032] 3. The rollers are positioned outside the counterweight plate to save assembly space and can accommodate larger rolls of packaging paper. The arrangement of multiple rollers can achieve simultaneous feeding of multiple rolls of packaging paper, thereby improving packaging efficiency.

[0033] 4. The design of the steel rods optimizes the guiding path of the packaging paper, ensuring uniform winding tension. When the annular rotating plate rotates at high speed, the three steel rods can prevent the lighter film from flying out due to excessive rotation speed. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0039] This application discloses a rotary wire reel packaging tray.

[0040] like Figure 1 The rotary wire coil packaging reel includes an annular rotating plate 1 with a notch 2. The annular rotating plate 1 has a C-shaped structure, and the spring steel wire coil can be inserted into the annular rotating plate 1 through the notch 2. The distance from the upper end to the lower end of the notch 2 is higher than the height of the spring steel wire coil. Three counterweight plates 6 are bolted to one side of the annular rotating plate 1. The three counterweight plates 6 are equidistantly distributed along the contour of the annular rotating plate 1. A winding roller 3 is welded to the side of the counterweight plate 6 away from the center of the annular rotating plate 1. The winding roller 3 is used to place the packaging paper 4. Three sets of steel rods 5 are welded to the annular rotating plate 1. Each set of steel rods 5 is spaced apart from the counterweight plates 6. There are three steel rods in each set. The middle steel rod 5 is used to place the film roll. The other two steel rods 5 prevent the film roll from flying out due to centrifugal force during the high-speed rotation of the annular rotating plate 1 due to its small mass. The packaging paper 4 passes between adjacent steel rods 5 and is attached to the circumference of the steel rods 5. That is, the packaging paper 4 is wrapped around several steel rods 5 in a wave shape and then wound onto the spring steel wire coil.

[0041] The roller 3 is located on the outer side of the annular rotating plate 1 away from the center, which can accommodate packaging paper 4 with a larger radius and is suitable for spring steel wire rolls with a larger ring width. Since the steel rods 5 are located on the inner side of the annular rotating plate 1 closer to the center than the roller 3, the free winding length of the packaging paper 4 and the film roll is shortened, reducing the problem of poor packaging effect caused by the twisting and tangling of the packaging paper 4 and the film roll. When the cross-sectional center of the spring steel wire roll is not concentric with the center of the annular rotating plate 1, the linear velocity of the part of the packaging paper 4 near the spring steel wire roll will change. However, since the packaging paper 4 is wound on multiple steel rods 5, the linear velocity of the unwinding of the packaging paper 4 can be kept as stable as possible, and the packaging paper 4 will not loosen all at once, and can still maintain a stable traction force.

[0042] The annular rotating plate 1 has a first guide groove 7 and a second guide groove 8. The first guide groove 7 is located on the side of the annular rotating plate 1 away from the counterweight block and is distributed along the outline of the annular rotating plate 1. The second guide groove 8 is arranged along the outer side wall of the annular rotating plate 1.

[0043] This application also discloses a wrapping and packaging device, in which a rotary wire roll packaging reel is applied.

[0044] like Figure 2 The winding and packaging device includes a workbench 9, a first drive assembly 10, a second drive assembly 11, and a feeding assembly 12. The feeding assembly 12 is used to support the horizontally placed spring steel wire coil, enabling the spring steel wire coil to rotate around the central axis of the workbench 9. The feeding assembly 12 is distributed around the workbench 9 as the center and is fixedly connected to the workbench 9 by a connecting rod. The rotary wire coil packaging reel is vertically arranged on the first drive assembly 10. The first drive assembly 10 is used to control the rotation of the annular rotating plate 1 along its own central axis. The second drive assembly 11 is used to drive the first drive assembly 10 and the annular rotating plate 1 to move towards the feeding assembly 12, so that the spring steel wire extends into the annular rotating plate 1 through the notch 2 of the annular rotating plate.

[0045] like Figure 3The first drive assembly 10 includes a movable base 101 and a first motor 102. A guide block 13 is provided on the movable base 101, and a first guide groove 7 is inserted into the fixed block, so that the annular rotating plate 1 is rotatably connected to the movable base 101. A plurality of guide wheels 103 are installed on the movable base 101. The plurality of guide wheels 103 are arranged around the central axis of the annular rotating plate 1. The guide wheels 103 extend into the second guide groove 8 on one side facing the annular rotating plate 1 and abut against the inner wall of the second guide groove 8. The first motor 102 is installed at the bottom of the movable base 101 and connected to one of the guide wheels 103. The guide wheel 103 drives the annular rotating plate 1 to rotate, and the remaining guide wheels 103 follow the annular rotating plate 1. The annular rotating plate 1 is vertically arranged on the movable base 101. The first motor 102 and the guide wheels 103 are used to control the rotation of the annular rotating plate 1 along its own central axis.

[0046] The second drive assembly 11 includes a track seat 111 and a mounting platform 112. The track seat 111 is installed on the ground and connected to the worktable 9. The movable seat 101 is slidably connected to the track seat 111. The mounting platform 112 is fixed to one side of the track seat 111. The movable seat 101 is located between the annular rotating plate 1 and the mounting platform 112. A hydraulic cylinder 113 is fixedly connected to the mounting platform 112. The hydraulic cylinder 113 is connected to the movable seat 101. The hydraulic cylinder 113 drives the movable seat 101 to move along the track seat 111 toward the feeding assembly 12 until the spring steel wire coil extends into the annular rotating plate 1.

[0047] like Figure 2The feeding assembly 12 includes four motor mounts 121, which are arranged in a circular pattern with equal intervals around the central axis of the worktable 9. Each motor mount 121 is connected to the worktable 9 via a connecting rod. A second motor 122 is mounted on the bottom of each of the four motor mounts 121. Each motor mount 121 is rotatably connected to a drive roller 123. The second motor 122 drives the drive roller 123 to rotate via a belt. A first support roller 125 is mounted on each motor mount 121, adjacent to the drive roller 123. A track seat 111 is positioned between two adjacent motor mounts 121. A support seat 126 is positioned between each of the remaining two adjacent motor mounts 121. The support seats 126 are fixedly connected to the worktable 9 via connecting rods. A second support roller 127 is rotatably connected to the support base 126. The drive roller 123, the first support roller 125, and the second support roller 127 jointly support the spring steel wire coil. The drive roller 123 rolls, driving the first support roller 125 and the second support roller 127 to roll and transmit the spring steel wire coil. The drive roller 123, the first support roller 125, and the second support roller 127 are horizontally positioned facing the center of the worktable 9. The central axes of the drive roller 123, the first support roller 125, and the second support roller 127 all intersect at the same point on the central axis of the worktable 9. A limit post 124 is rotatably connected to the side of the motor base 121 near the center of the worktable 9. The limit post 124 abuts against the inner diameter of the spring steel wire coil to ensure the stability of the spring steel wire coil feeding process. In this embodiment, the limit post 124 is made of rubber; in other embodiments, the surface of the limit post 124 can be made of sponge.

[0048] The implementation principle of this application embodiment is as follows: Before the equipment is started, the packaging paper 4 is installed on the roller 3, and the packaging film is installed on the middle steel rod 5. The spring steel wire roll is placed flat on the drive roller 123, the first support roller 125, and the second support roller 127 using a hook. First, the hydraulic cylinder 113 is started. The hydraulic cylinder 113 controls the rotary wire packaging disc and the moving seat 101 to move together along the track direction until the spring steel wire roll can be inserted into the annular rotating plate 1. The packaging paper 4 and the film are wrapped around the steel rod 5 in a wave-like pattern and then wound onto the spring steel wire roll. The first motor 102 and the second motor 122 are started. The rotary wire packaging disc starts to rotate in the vertical direction, driving the packaging paper 4 and the film to start winding. The drive roller 123 drives the first support roller 125 and the second support roller 127 to convey the spring steel wire roll, realizing the full packaging of the spring steel wire.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
