Description

Technical Field

[0001] This application relates to the technical field of material winding devices, and particularly to a servo cloth winding mechanism for a circular loom. Background Art

[0002] After the fabric is woven, it usually needs to be wound up for convenient packing and transportation. The fabric is usually wound on a cylindrical winding base column. Since the winding base column needs to be connected to the driving mechanism to achieve the winding operation, a structure capable of being connected to the output end of the driving mechanism is usually designed at the end, which needs to protrude from both ends of the wound fabric. Therefore, the winding base column can only be placed horizontally with its axis, and cannot be placed vertically with its axis, let alone stacked vertically. If the horizontally placed cylindrical fabric roll is not constrained by additional components, it is very easy to roll during transportation, which affects both the transportation safety and the stability. Summary of the Utility Model

[0003] The purpose of this application is to provide a servo cloth winding mechanism for a circular loom that can place the fabric roll vertically.

[0004] To achieve the above purpose, this application provides a servo cloth winding mechanism for a circular loom: including a frame, a rotary drive is fixedly connected to the frame, and a telescopic drive is also fixedly connected to the output end of the rotary drive. The telescopic drive includes a cooperating cylinder barrel and a telescopic rod. The cylinder barrel is movably connected to an inner lining plate through a first connecting rod and a second connecting rod. The inner lining plate is always parallel to the rotation axis of the telescopic drive. The second connecting rod is far from the rotary drive. A transmission rod is movably connected between the movable end of the telescopic rod and the second connecting rod. There are at least two of the inner lining plates, and these inner lining plates are arranged equidistantly around the rotation axis of the telescopic drive to provide a uniformly radial supporting force for the hollow fabric tube.

[0005] As a preference, a first inner hinge frame and a second inner hinge frame are fixedly connected to the outer side surface of the cylinder barrel. The first inner hinge frame is closer to the rotary drive than the second inner hinge frame. A first outer hinge frame and a second outer hinge frame are fixedly connected to the surface of the inner lining plate facing the telescopic drive. The first outer hinge frame is closer to the rotary drive than the second outer hinge frame. One end of the first connecting rod is rotatably connected to the first inner hinge frame and the other end is rotatably connected to the first outer hinge frame. One end of the second connecting rod is rotatably connected to the second inner hinge frame and the other end is rotatably connected to the second outer hinge frame, so that the first connecting rod and the second connecting rod move synchronously.

[0006] As a preference, a relief groove is formed at the movable end of the telescopic rod. An articulated shaft is arranged in the telescopic rod within the relief groove. One side of the second connecting rod close to the cylinder barrel has an extension plate. One end of the transmission rod is rotatably connected to the articulated shaft and the other end is rotatably connected to the extension plate, for transmitting the power of the telescopic drive to the connecting rod structure.

[0007] As a preference, the closest ends of several of the transmission rods to the cylinder barrel are closer to each other, such that when the telescopic rod extends, the inner lining plate expands outwards; when the telescopic rod retracts, the inner lining plate moves closer.

[0008] As a preference, the first connecting rod and the second connecting rod are of equal length, and the distance between the first inner articulated frame and the second inner articulated frame is equal to the distance between the first outer articulated frame and the second outer articulated frame, forming a parallelogram structure to ensure that the inner lining plate is always parallel to the cylinder barrel.

[0009] As a preference, the cylinder barrel and the telescopic rod together form a hydraulic cylinder. The outer side of the inner lining plate facing away from the telescopic drive is a cylindrical arc surface. Friction grooves are also formed on the outer side of the inner lining plate to increase the contact friction between the inner lining plate and the cloth winding cylinder.

[0010] As a preference, the frame includes a support. The cylinder barrel is fixedly connected to the output end of the rotary drive through a configuration disk. The rotary drive includes a servo motor and a speed reducer fixedly connected to one side of the support. The configuration disk is located on the other side of the support, with a compact fit and high stability.

[0011] As a preference, the configuration disk includes a limit ring. One end of the limit ring is fixedly connected to the cylinder barrel and the other end has a main shaft. The main shaft passes through the support and is fixedly connected to the output end of the speed reducer; a base is connected below the support to improve the placement stability of the entire servo cloth winding mechanism.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] (1) By designing a retractable inner lining plate structure, the base column for winding the cloth is replaced with a hollow cloth winding cylinder, and the cloth winding cylinder does not need to be provided with protruding connection structures at both ends. Therefore, after the cloth is wound, it can be placed vertically with its axis and stacked vertically. Even without providing additional constraint structures for the cloth roll, rolling will not occur, improving the transportation safety and stability;

[0014] (2) This cloth winding mechanism can cooperate and link with the cloth cylinder without the need to provide connection structures at the ends of the cloth cylinder, making the component structure on which the center of the cloth roll depends simpler, with lower usage costs. Moreover, since the cloth roll is hollow, it is also convenient for packaging and lifting operations. Description of the Drawings

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily need to be used to describe a specific order or sequence.

[0027] The terms "comprising" and "having" in the description and claims of the present application, as well as any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0028] As Figure 1-8 shown in the circular loom servo cloth winding mechanism, it includes a fixedly arranged frame 1. A rotary drive 2 is fixedly connected to the frame 1. Only the housing of the rotary drive 2 is fixed, and the output end of the rotary drive 2 is not fixed. The output end of the rotary drive 2 is also fixedly connected to a telescopic drive 4. The specific structure of the telescopic drive 4 includes a cooperating cylinder barrel 410 and a telescopic rod 420. Generally, the cylinder barrel 410 and the telescopic rod 420 together form a hydraulic cylinder, which can provide a stable and large enough acting force outward. The cylinder barrel 410 is movably connected to an inner lining plate 8 through a first connecting rod 6 and a second connecting rod 7 for directly contacting the inner wall of the cloth winding cylinder. The outer side surface of the inner lining plate 8 facing away from the telescopic drive 4 is a cylindrical arc surface, which can fit the inner wall of the cloth winding cylinder as much as possible. A friction groove 803 is also provided on the outer side surface of the inner lining plate 8, which can improve the contact friction force between the inner lining plate 8 and the cloth winding cylinder, thereby preventing the cloth winding cylinder from slipping relative to the inner lining plate 8 or detaching from the inner lining plate 8 during the cloth winding process.

[0029] The inner lining plate 8 is always parallel to the rotation axis of the telescopic drive 4. To achieve this effect, a first inner hinge frame 411 and a second inner hinge frame 412 are fixedly connected to the outer side surface of the cylinder barrel 410, and the first inner hinge frame 411 is closer to the rotary drive 2 than the second inner hinge frame 412; also, a first outer hinge frame 801 and a second outer hinge frame 802 are fixedly connected to the surface of the inner lining plate 8 facing the telescopic drive 4, and the first outer hinge frame 801 is also closer to the rotary drive 2 than the second outer hinge frame 802. Moreover, the first connecting rod 6 and the second connecting rod 7 are of equal length. At the same time, the distance between the first inner hinge frame 411 and the second inner hinge frame 412 is equal to the distance between the first outer hinge frame 801 and the second outer hinge frame 802. One end of the first connecting rod 6 is rotatably connected to the first inner hinge frame 411, and the other end is rotatably connected to the first outer hinge frame 801. One end of the second connecting rod 7 is rotatably connected to the second inner hinge frame 412, and the other end is rotatably connected to the second outer hinge frame 802. In this way, the cylinder barrel 410, the first connecting rod 6, the second connecting rod 7, and the inner lining plate 8 form a parallelogram structure, and the relative side edges always remain parallel.

[0030] As can be seen from the above structural design, the second connecting rod 7 is far from the rotary drive 2 but close to the movable end of the telescopic rod 420. A transmission rod 5 is movably connected between the movable end of the telescopic rod 420 and the second connecting rod 7. Specifically: a relief groove 421 is formed at the movable end of the telescopic rod 420, and a hinge shaft 422 is arranged in the relief groove 421 of the telescopic rod 420. Generally, the hinge shaft 422 is inserted into the relief groove 421 from the side of the telescopic rod 420. One side of the second connecting rod 7 close to the cylinder barrel 410 has an extension plate 701, and the extension direction of the extension plate 701 is usually perpendicular to the main direction of the second connecting rod 7. One end of the transmission rod 5 is embedded in the relief groove 421 and rotatably connected to the hinge shaft 422, and the other end is rotatably connected to the extension plate 701. The ends of all the transmission rods 5 closest to the cylinder barrel 410 are closer to each other. That is to say, the distance between the ends of the transmission rods 5 far from the cylinder barrel 410 is larger than the distance between the ends of the transmission rods 5 close to the cylinder barrel 410, and as shown in the figure, it is always like this.

[0031] There are at least two inner lining plates 8. In this embodiment, there are four groups of combinations of the inner lining plates 8, the first connecting rod 6, the second connecting rod 7, and the transmission rod 5. To make the installation of these four structures more convenient, the outer side surface of the cylinder barrel 410 is adaptively designed to be a quadrangular prism shape. The four groups of parallelograms are respectively located on four side surfaces, and there are also four groups of relief grooves 421 and hinge shafts 422 provided on the telescopic rod 420. Therefore, these inner lining plates 8 are arranged at equal distances around the rotation axis of the telescopic drive 4, and uniformly apply force to the cloth winding cylinder.

[0032] The frame 1 includes a vertical support 102. The cylinder barrel 410 is fixedly connected to the output end of the rotary drive 2 through the configuration disk 3. Specifically: The rotary drive 2 includes a servo motor 201 and a speed reducer 202 fixedly connected to one side of the support 102. The output end of the servo motor 201 is connected to the input end of the speed reducer 202 to increase the torque by reducing the speed. The rotation axis of the output end of the speed reducer 202 is generally set in the horizontal direction. The configuration disk 3 is located on the other side of the support 102, and the support 102 is sandwiched in the middle. The main body part of the configuration disk 3 is a limit ring 302. The diameter of the limit ring 302 is greater than the maximum span of the inner lining plate 8 in the maximum unfolded state. Therefore, the limit ring 302 can provide a mounting and positioning function for the cloth winding cylinder sleeved outside the inner lining plate 8. One end of the limit ring 302 is fixedly connected to the cylinder barrel 410, and the other end has a main shaft 301. The main shaft 301 passes through the support 102 and is fixedly connected to the output end of the speed reducer 202. In order to ensure that the cloth winding mechanism is evenly stressed during rotation, the rotation axis of the output end of the speed reducer 202, the main shaft 301, and the axis of the limit ring 302 are collinear with the axis of the cylinder barrel 410; A base 101 is also connected below the support 102. The base 101 is located below the telescopic drive 4 and the inner lining plate 8. The entire cloth winding mechanism, together with the cloth winding cylinder and the center of the fabric that may be added later, all fall above the base 101, which can effectively ensure the stability of the entire servo cloth winding mechanism during operation.

[0033] Working principle: This fabric winding mechanism is suitable for cooperating with a hollow fabric winding cylinder. The axial length of the fabric winding cylinder can be less than or equal to the width of the fabric. In the initial state of this mechanism, the telescopic rod 420 is retracted into the cylinder barrel 410. Driven by the transmission rod 5, all the connecting rods are forced to approach the cylinder barrel 410. At the same time, all the inner lining plates 8 approach each other. At this time, the inner lining plates 8 are in a retracted state, and the contour is significantly smaller than the inner diameter of the fabric winding cylinder. The fabric winding cylinder can be easily sleeved outside all the inner lining plates 8. Then, start the telescopic drive 4 to extend the telescopic rod 420 out of the cylinder barrel 410. Driven by the transmission rod 5, all the connecting rods make all the inner lining plates 8 separate from each other until they are in close contact with the inner wall of the fabric winding cylinder. At this time, one end of the fabric winding cylinder abuts against the end face of the limit ring 302, and the fabric winding cylinder is fixed on this fabric winding mechanism. Driven by the rotation drive 2, it can rotate to wind the fabric to be wound into a cylindrical shape. Because the servo motor 201 can perform precise speed control, during the winding process, the rotation speed of the fabric winding cylinder can be adaptively adjusted according to the descending speed of the fabric to make the descending speed of the fabric consistent with the winding speed. When the winding thickness reaches the upper limit, the rotation can be stopped. The telescopic rod 420 makes all the connecting rods return to the initial position through the transmission rod 5, and the inner lining plates 8 release the tension on the fabric winding cylinder. The fabric cylinder filled with materials will naturally slide off this fabric winding mechanism. Repeat the above operations, replace with a new fabric winding cylinder, and the winding work of the fabric can continue. Since the two ends of the hollow fabric winding cylinder do not protrude beyond the two ends of the fabric roll, the packaged finished products can be placed vertically with the axis, and can even be stacked.

[0034] The above describes the basic principle, main features and advantages of this application. Those skilled in the art should understand that this application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed. The scope of protection required by this application is defined by the appended claims and their equivalents.
