Description

Technical Field

[0001] The utility model belongs to the technical field of coiling machines, and particularly relates to a hollow type center coiling machine. Background Art

[0002] A coiling machine is an auxiliary equipment in a rolling mill workshop that coils hot-rolled or cold-rolled steel into a reel shape. It is arranged behind the finishing stand in a hot strip continuous rolling mill, a cold strip continuous rolling mill, and a wire rod rolling mill; in a single-stand reversible cold strip rolling mill, it is installed in front of and behind the rolling mill. In addition, it is also installed in various finishing units such as continuous pickling units, slitting, annealing, and coating. Coiling machines are used in many industries, and the steel plate coiling machine in the metallurgical industry is the most representative, and the drive comes from electricity and fluid.

[0003] A fully automatic coiling machine for TPU composite sheets disclosed in Patent CN210260518U includes a frame; a sheet material inlet roller rotatably arranged on the frame; at least one transition roller located downstream of the sheet material inlet roller; a coiling device installed on the frame and located downstream of at least one transition roller, the coiling device including at least one coiling shaft; a cutting device installed on the frame and used for cutting the TPU composite sheet; a winding device installed on the frame and located upstream of the coiling device, the winding device including a friction roller movably arranged on the frame in the front-back direction; a center coiling mechanism capable of driving the friction roller to move so that a gap is formed between the friction roller and the coiling shaft; a friction coiling mechanism capable of driving the friction roller to move so that the friction roller is in frictional contact with the coiling shaft. When one of the center coiling mechanism and the friction coiling mechanism is in a working state, the other is in a non-working state, and it can achieve center coiling and friction coiling on one device, which is more convenient in operation.

[0004] In the above solution, by setting a center coiling mechanism and a friction coiling mechanism, the friction roller is movably arranged on the frame in the front-back direction, and the center coiling mechanism can drive the friction roller to move so that a gap is formed between the friction roller and the coiling shaft, thereby simplifying the equipment structure, reducing the floor area, and being more convenient in operation. However, on the coiling device, the center shaft penetrates the entire device, occupying the placement space of the coiled material, so that when coiling the same coiled material, the equipment needs to occupy more space. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and provide a hollow type center coiling machine that can solve the above technical problems.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The hollow type center coiler includes a base platform, on which a rotating roller frame is rotatably arranged. The rotation axis of the rotating roller frame is in transmission connection with a roller frame motor. A coiled material avoidance space is formed on the rotation axis of the rotating roller frame. In the coiled material avoidance space, there is a coiling roller arranged parallel to the rotation axis of the rotating roller frame. Both ends of the coiling roller are respectively connected to the rotating roller frame deviating from the rotation axis.

[0008] In the above-mentioned hollow type center coiler, the rotating roller frame includes two cross turntables symmetrically arranged on both sides of the coiled material avoidance space. The rotation axis of the cross turntable is connected to the base platform, and the coiling roller is arranged on the cross turntable.

[0009] In the above-mentioned hollow type center coiler, the cross turntable includes a coiling roller plate and a guide roller plate. The coiling roller plate and the guide roller plate are stacked crosswise and lean against each other, and the stacked part is rotatably connected to the base platform.

[0010] In the above-mentioned hollow type center coiler, a coiling roller motor is arranged at the end of the coiling roller plate. The coiling roller motor is in transmission connection with one end of the coiling roller, and the coiling roller connects the two symmetric coiling roller plates on both sides.

[0011] In the above-mentioned hollow type center coiler, guide rollers are rotatably arranged at both ends of the guide roller plate, and the guide rollers connect the two symmetric guide roller plates on both sides.

[0012] In the above-mentioned hollow type center coiler, a feeding coiling roller frame is arranged on the base platform, and the feeding coiling roller frame is correspondingly arranged beside the guide roller.

[0013] In the above-mentioned hollow type center coiler, two strip-shaped protrusions are arranged at the rotation axis of the guide roller plate, and the coiling roller plate is clamped in the card slot formed by the two strip-shaped protrusions.

[0014] In the above-mentioned hollow type center coiler, the roller frame motor is arranged in the base platform, and the roller frame motor is in transmission connection with the rotation axis of one of the cross turntables.

[0015] In the above-mentioned hollow type center coiler, a limiting mechanism is further arranged in the base platform, and the limiting mechanism abuts against the rotating shaft of the cross turntable on the side far from the roller frame motor.

[0016] In the above-mentioned hollow type center coiler, the limiting mechanism includes a limiting rod and a limiting wheel. The limiting wheel is fixedly sleeved on the rotating shaft, and one end of the limiting rod extends into the limiting groove formed on the limiting wheel.

[0017] The advantages of the present utility model are as follows:

[0018] Both ends of the rotating roller frame are rotatably connected to the base platform, eliminating the rotating shaft that usually runs through the entire rotating roller frame, leaving more space at the axis position for placing the coil material, enabling the equipment to wind coils with a larger diameter under the same space occupation. At the same time, the cross turntable is fixedly connected by using the winding rollers and guide rollers in the rotating roller frame, which can also ensure the overall stability of the rotating roller frame.

Detailed Description of the Preferred Embodiments

[0023] The following are specific embodiments of the utility model and in conjunction with the drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0024] As Figures 1 - 3 shown, a hollow type center coiling machine includes a base platform 1, a rotating roller frame 2 is rotatably arranged on the base platform 1, the rotation axis center of the rotating roller frame 2 is in transmission connection with a roller frame motor 11, a coil material avoidance space is provided at the rotation axis center of the rotating roller frame 2, and a winding roller 21 parallel to the rotation axis center of the rotating roller frame 2 is arranged in the coil material avoidance space. Both ends of the winding roller 21 are respectively deviated from the rotation axis center and connected to the rotating roller frame 2.

[0025] That is, in the usual rotating roller frame 2, the part that runs through the roller frame is cancelled, and the winding roller 21 is used as the connection and transmission structure in the rotating roller frame 2. This not only leaves more space in the rotating roller frame 2 for storing the coil material, enabling the equipment to wind coils with a larger diameter under the same space occupation, but also can maintain the stable rotation of the rotating roller frame 2.

[0026] In this embodiment, the rotating roller frame 2 includes two cross turntables symmetrically arranged on both sides of the coil material avoidance space. The rotation axis center of the cross turntable is connected to the base platform 1, and the winding roller 21 is arranged on the cross turntable.

[0027] The two cross turntables are connected by two winding rollers 21. The winding rollers 21 are respectively installed on two corresponding protrusions among the four protrusions of the cross turntable. Omitting the penetrating rotating shaft in the middle will leave more space for the two winding rollers 21, allowing more coil materials to be wound on each winding roller 21.

[0028] Preferably, the cross turntable includes a winding roller plate 23 and a guide roller plate 24, and the winding roller plate 23 and the guide roller plate 24 are cross-staggered and stacked together, and the stacked position is rotatably connected to the base 1.

[0029] The cross turntable is formed by two long plates stacked vertically at the center and connected together on the rotating shaft. The cross turntable formed by two long plates of equal length can maintain good balance when rotating at the center. At the same time, if the winding roller or guide roller needs to be replaced, just disassemble and install the corresponding long plate.

[0030] In this embodiment, a roller motor 25 is disposed at the end of the roller plate 23 , and the roller motor 25 is drivingly connected to one end of the roller 21 , and the roller 21 connects the roller plates 23 symmetrically on both sides.

[0031] When winding, the roller 21 needs to actively rotate to tighten the coil, so the roller motor 25 is installed at the positions where the roller 21 is connected at both ends of the roller plate 23 to drive the rotation of the roller 21 alone. Usually, the roller motor 25 is driven only from one end of the roller 21, but when processing a wide or rigid coil, in order to maintain the torsional balance on both sides of the roller 21, the roller motor 25 is used to drive both ends of the roller 21 together.

[0032] In this embodiment, guide rollers 22 are rotatably provided at both ends of the guide roller plate 24 , and the guide rollers 22 connect the guide roller plates 24 symmetrically on both sides.

[0033] Because the through connection of the central position shaft is abandoned, the cross turntable formed by the guide roller plate 24 and the winding roller plate 23 further enhances the stability of the rotating roller frame 2 by connecting the guide roller 22. The guide roller 22 itself only guides the transitional coil and does not bear much pressure, so the guide roller 22 can be set at a position farther from the rotation center to bear more supporting force.

[0034] Preferably, a winding roller frame 12 is provided on the base 1, and the winding roller frame 12 is correspondingly arranged beside the guide roller 22, so that the coiled material can smoothly enter the guide roller 22 and be smoothly rolled into the winding roller 21 after being tensioned by the guide roller 22.

[0035] In this embodiment, two strips of shaped protrusions are provided at the rotation axis of the guide roller plate 24, and the winding roller plate 23 is inserted into the grooves formed by the two strips of shaped protrusions.

[0036] The winding roller plate 23 and the guide roller plate 24 are respectively fixedly connected to the rotating shaft, so that the winding roller plate 23 and the guide roller plate 24 can be kept in a perpendicular state to each other during installation. The card groove formed by the two shaped protrusions can greatly facilitate the installation process, and can also prevent the winding roller plate 23 and the guide roller plate 24 from rotating out of sync when the cross turntable rotates.

[0037] In this embodiment, the roller frame motor 11 is arranged in the base 1, and the roller frame motor 11 is in driving connection with the rotation axis of one of the cross turntables.

[0038] The roller frame motor 11 is mainly used for the rotation displacement of the coil rollers 21 on the roller frame 2 for feeding. Usually, it rotates 180° at a time to exchange the positions of the two coil rollers 21 with each other. Since the workload of the roller frame motor 11 is not large and there are not many precision requirements, only one roller frame motor 11 is arranged on one side of the rotating roller frame 2 for driving.

[0039] Of course, for large coils, in order to protect the rotating shaft and the rotating roller frame 2, roller frame motors 11 can be arranged on both ends of the rotating roller frame 2 for driving.

[0040] Preferably, a limiting mechanism is further arranged in the base 1, and the limiting mechanism abuts against the rotating shaft of the cross turntable on the side away from the roller frame motor 11.

[0041] The limiting mechanism includes a limiting rod 31 and a limiting wheel 32. The limiting wheel 32 is fixedly sleeved on the rotating shaft, and one end of the limiting rod 31 extends into the limiting groove formed in the limiting wheel 32.

[0042] On the base 1 on the opposite side of the rotating roller frame 2 connected to the roller frame motor 11, a limiting mechanism is arranged around the rotating shaft here. A limiting wheel 32 is fixedly installed on the rotating shaft. Two limiting holes or limiting grooves are symmetrically formed in the limiting wheel 32. And a telescopic limiting rod 31 is installed in the base on this side. The limiting rod 31 is driven axially to enter and exit the limiting holes or limiting grooves by a cylinder or a motor.

[0043] Before the rotating roller frame 2 needs to rotate, the limiting rod 31 withdraws from the hole or groove. Subsequently, while the rotating roller frame 2 flips, the hole or groove rotates to the one that was opposite before. The limiting rod 31 extends out again and inserts into the hole or groove to fix the rotating roller frame 2 at the current angle.

[0044] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
