Description

Technical Field

[0001] The utility model relates to the technical field of strip winding mechanisms, in particular to a winding rack for coated strips. Background Art

[0002] A coated strip refers to a strip formed by compounding a plastic outer layer on the surface of a metal strip (such as a steel strip). It is an intermediate product in the processing of corrugated pipes and is used for processing corrugated pipes.

[0003] During the production of corrugated pipes, their corrugated features are processed from coated strips. Pipe manufacturers first produce coated strips, then wind the produced coated strips onto a coil, and then transfer the coated strips wound on the coil to the corrugated production line through a lifting device.

[0004] Since the coated strip has steel sheets inside and is coated with plastic outside, it has a certain elasticity. Therefore, during the transfer process of the coil, if the outermost circle of the coated strip is not fixed, there is a high risk of the coil getting disordered (the coated strip springing out) under its own elastic force, and even the winding may fail.

[0005] Therefore, there is an urgent need for a winding rack for coated strips to fix the outermost circle of the coated strip and prevent the coil from getting disordered under its own elastic force during the transfer process. Summary of the Utility Model

[0006] In view of the above technical problems, the utility model provides a winding rack for coated strips to solve the problem that the existing winding mechanism for coated strips lacks fixation of the outermost coated strip, resulting in the coil getting disordered under its elastic force.

[0007] The above technical object of the utility model is achieved through the following technical solutions:

[0008] A winding rack for coated strips includes a rotating frame, on which a coil is detachably installed. The coil includes a frame, and a plurality of support beams are vertically arranged in the same plane inside the frame. A winding drum is fixedly arranged at the center of the plurality of support beams.

[0009] At least one clamping and fixing mechanism is further arranged on the coil. The clamping and fixing mechanism includes a lead screw, which is rotatably arranged between the frame and the support beam. A slider is in threaded cooperation with the lead screw. A clamping block is detachably installed on the slider. A slide rail is arranged at the bottom of the clamping block, and the two ends of the slide rail are respectively fixed on the support beam and the frame.

[0010] An arc-shaped clamping opening is formed on one side of the clamping block close to the winding drum, and a limiting pressure plate is arranged at the top of the clamping block at the arc-shaped clamping opening.

[0011] Furthermore, a plurality of positioning holes are provided on one side of the sliding block, and positioning posts are provided at positions of the clamping block corresponding to the positioning holes, and the positioning posts are plug-fitted with the positioning holes.

[0012] Furthermore, a side of the sliding block close to the reel is flush with the top surface of the support beam.

[0013] Furthermore, the height of the arc-shaped clamp is greater than the width of the plastic-coated belt.

[0014] Furthermore, a rubber pad is provided on the arc-shaped clamping opening.

[0015] Furthermore, a driving disk is provided at one end of the lead screw located outside the frame.

[0016] Furthermore, the lead screw is provided with a hexagonal drive head at the center of the drive disk.

[0017] In summary, the beneficial technical effects of the utility model are:

[0018] (1) The rotation of the lead screw drives the slider and the clamping block to move along the slide rail, so that the outermost circle of the rolled plastic-coated tape can be clamped and fixed, preventing the plastic-coated tape from rebounding outward under the action of its own elastic force, thus avoiding the problem of disorderly winding.

[0019] (2) The detachable connection between the slider and the clamp block is realized by the cooperation of the positioning column and the positioning hole. The clamp block can be removed when winding and installed after winding. This can avoid the interference of the clamp block with the plastic-coated tape during winding.

[0020] (3) The arc-shaped clamping mouth increases the contact area between the clamping block and the plastic-coated belt, making the clamping more stable. At the same time, the limiting pressure plate is used to prevent the longitudinal jump of the plastic-coated belt.

[0021] (4) Use rubber pads to protect the coating of the plastic-coated belt to the greatest extent possible to prevent the clamp from directly contacting the plastic-coated belt. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0027] The present utility model will be clearly and completely described below in conjunction with embodiments.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0029] In the description of the embodiments, unless otherwise clearly specified and limited, terms such as "arrangement" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or connected through an intermediate medium, or there can be a connection inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] See the attached Figures 1-4 , which shows a plastic-coated tape winding rack, including a rotating frame 1. A turntable 3 is rotatably arranged on the top of the rotating frame 1. The turntable 3 is driven by a driving motor 2 at the inner bottom of the rotating frame 1. Four fixed columns 4 are arranged in a rectangular shape on the turntable 3. A material tray 5 is inserted on the turntable 3 through the fixed columns 4;

[0031] The material tray 5 includes an octagonal frame 6. Four support beams 7 are arranged in a cross shape inside the frame 6. The four support beams 7 form a cross-shaped structure. Fixing holes are provided at the positions of the four support beams 7 corresponding to the fixed columns 4. The material tray 5 is connected to the turntable 3 through the insertion fit of the fixing holes and the fixed columns 4. A reel 8 is fixedly arranged in the center of the four support beams 7. When winding, one end of the plastic-coated tape 20 is fixed on the reel 8, and then the material tray 5 is driven by the driving motor 2 and, with the cooperation of a traction device, the plastic-coated tape 20 is wound around the reel 8;

[0032] A lead screw 9 is rotatably provided between the frame 6 and the opposite support beam 7. One end of the lead screw 9 extends outside the frame 6 and is provided with a driving disk 17 for rotation. A slider 10 is provided on the lead screw 9 through threaded engagement. A slide rail 11 is slidably provided at the bottom of the slider 10. Both ends of the slide rail 11 are fixed to the opposite support beam 7 and the frame 6. The top surface of the slider 10 is flush with the top surface of the support beam 7, thus avoiding interference with the plastic-coated tape 20 due to the protrusion of the slider 10 during winding.

[0033] Further, a clamping block 12 for clamping and fixing the outermost circle of the plastic-coated tape 20 is provided on the slider 10. During use, the driving disk 17 drives the lead screw 9 to rotate, and the lead screw 9 further drives the clamping block 12 to fit against the side wall of the outermost circle of the plastic-coated tape 20 to achieve clamping and fixing, thus avoiding the occurrence of disorderly winding caused by the reverse rebound of the plastic-coated tape 20 under its own elastic force.

[0034] Further, in order to avoid interference of the clamping block 12 with the plastic-coated tape 20 during winding, two positioning holes 15 are provided on one side of the slider 10 where the clamping block 12 is located. The connection line between the two positioning holes 15 is perpendicular to the axis of the lead screw 9. The clamping block 12 is provided with positioning posts 16 corresponding to the positioning holes 15. The positioning posts 16 are inserted and matched with the positioning holes 15. When the clamping block 12 is removed from the slider 10 during normal winding, and after winding is completed, the clamping block 12 is inserted onto the slider 10 through the positioning posts 16, and then the lead screw 9 drives the clamping block 12 to clamp and fix the outermost circle of the plastic-coated tape 20.

[0035] Further, since the end position of the outermost circle of the plastic-coated tape 20 is not fixed during winding, in order to better clamp and fix the plastic-coated tape 20, two clamping blocks 12 are symmetrically arranged on the material disk 5, thus increasing the clamping range of the plastic-coated tape 20, and it can be fixed at a nearby position regardless of where the winding ends.

[0036] Further, in order to increase the contact area between the clamping block 12 and the plastic-coated tape 20 and make the clamping more sufficient, an arc-shaped clamping opening 13 is provided on one side of the clamping block 12 corresponding to the winding drum 8, and the height of the arc-shaped clamping opening 13 is greater than the width of the plastic-coated tape 20. A rubber pad 19 is adhered to the arc-shaped clamping opening 13. The rubber pad 19 reduces the rigidity when the clamping block 12 contacts the plastic-coated tape 20 and avoids damage to the coating. At the same time, a limiting pressure plate 14 is provided at the top of the clamping block 12 at the arc-shaped clamping opening 13, and the limiting pressure plate 14 can limit the top of the plastic-coated tape 20 to prevent the plastic-coated tape 20 from winding disorderly in the longitudinal direction.

[0037] Further, in order to increase the movement speed of the clamping block 12, a hexagonal driving head 18 is provided at the center of the driving disk 17. The hexagonal driving head 18 can be matched with the bit on the electric drill, and the electric drill drives the lead screw 9 to rotate.

[0038] In use, first remove the clamping block 12 from the slider 10, then fix one end of the plastic-coated tape 20 on the reel 8, and the other end of the plastic-coated tape 20 is still connected to the traction device. Then start the drive motor 2 to drive the material tray 5 to rotate. At this time, the plastic-coated tape 20 can start to be wound around the reel 8. When the winding is completed, install the clamping block 12 on the slider 10 through the positioning post 16, and then use a hand drill or manually rotate the lead screw 9 to fit the clamping block 12 onto the outermost plastic-coated tape 20 to achieve clamping and fixing.

[0039] The above is only the preferred specific implementation mode of the present invention, and does not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
