Description

Technical Field

[0001] The utility model relates to the technical field of the roller shaft positioning of a winding machine, in particular to an encircling cutting device for a winding machine. Background Art

[0002] In the related fields of winding machines, the positioning device is crucial for the stability and accuracy of the roller shaft. Most traditional winding machine positioning devices adopt the method of cylinder pressing, and the roller shaft is limited by pushing the supporting component through the cylinder. The working principle of such a device is to adjust the position of the roller shaft by air pressure pushing the actuating element to ensure that the roller shaft can maintain an accurate running state during the winding process of the coil material. This device is widely used in the winding equipment of coil materials such as paper, film, and textiles. However, with the growth of production requirements and the increase in equipment complexity, some problems have gradually emerged in this cylinder pressing method:

[0003] 1. Greatly affected by the external environment: The working performance of the cylinder system is easily affected by temperature and air pressure fluctuations. In high-temperature or low-temperature environments, the pressure in the cylinder is prone to fluctuate, resulting in unstable positioning accuracy. Especially during long-term operation, the positioning error will gradually appear, affecting the winding effect.

[0004] 2. Serious wear and limited service life: The cylinder system relies on continuous mechanical movement and air pressure pushing. Long-term use will cause component wear. Especially under high-load working conditions, the cylinder seals are easily damaged, resulting in equipment air leakage or positioning failure, increasing the equipment maintenance cost and affecting the production efficiency.

[0005] 3. Complicated structure and large occupied space: The cylinder system usually needs to be equipped with multiple pipelines, valves, and control systems. The whole structure is relatively complicated and occupies a large space. Especially in modern factories, the space layout of equipment is restricted, and the huge volume of the traditional cylinder system is not conducive to the space optimization of the factory.

[0006] To solve the above problems, a hydraulic system or an electric control system has been introduced in the industry, attempting to improve the positioning effect by improving the control accuracy and reducing the dependence on air pressure. However, these improvement measures have brought new problems to a certain extent: For example, the hydraulic system is also easily affected by temperature changes. Especially in cold environments, the viscosity of the hydraulic oil changes, and the system response speed decreases, affecting the positioning accuracy. Another example is that the electric system is complicated and difficult to maintain: Although the electric system can provide higher positioning accuracy, its control system is complicated, the failure rate of motors and sensors is relatively high, the maintenance cost is expensive, and the system operation is relatively cumbersome, which is not conducive to the quick operation and maintenance of on-site workers.

[0007] Therefore, how to improve the accuracy and stability of the roller shaft positioning, while reducing equipment wear, occupied space, and maintenance difficulty, has become the technical problem to be solved by the utility model. Utility Model Content

The frame 1 comprises a frame support rod 3 and two side panels 4. The two side panels 4 are fixedly connected by at least two frame support rods 3 to form a working space 5 between the two side panels 4. The embracing positioning device for the winding machine also comprises an embracing positioning mechanism.

[0033] The winding roller 2 includes a roller shaft 6, and the roller shaft 6 includes two positions close to the end, and the two positions close to the end are respectively placed and connected to two side plates 4 through an embracing positioning mechanism; the embracing positioning mechanism includes a sliding semicircular ring 9 and a supporting semicircular ring 8 with a U-shaped notch 7;

[0034] The supporting semicircular ring 8 is fixedly connected to the side plate 4; a sliding semicircular ring 9 is sleeved on the outer side of the supporting semicircular ring 8, and the annular center line of the supporting semicircular ring 8 and the annular center line of the sliding semicircular ring 9 are on the same straight line, so that the sliding semicircular ring 9 can slide in the radial direction along the annular outer side surface of the supporting semicircular ring 8;

[0035] A supporting annular column 10 matching the U-shaped notch 7 is provided near the end of the roller shaft 6. The supporting annular column 10 is sleeved on the roller shaft 6 and fixedly connected to the roller shaft 6. The supporting annular column 10 at the end of the roller shaft 6 is placed on the supporting semicircular ring 8 through the U-shaped notch 7.

[0036] The outer annular side surface of the sliding semicircular ring 9 is provided with a tooth surface 11; a motor 12 is fixedly provided on the side plate 4, and the motor 12 includes a motor shaft, and the motor shaft is linked to a gear 15, and the gear 15 is meshed with the tooth surface 11. The encircling cutting device for the winding machine also includes a protective cover 14, and the protective cover 14 is provided above the upper half of the tooth surface 11, and the protective cover 14 is fixedly connected to the frame 1.

[0037] The supporting semicircular ring 8 and the sliding semicircular ring 9 are connected with each other through an annular guide groove and an annular guide protrusion 16; Figure 2 As shown, the sliding semicircular ring 9 has a guide protrusion 1, and the supporting semicircular ring 8 has a guide groove that matches the guide protrusion 16, and the ring shapes of the two are respectively on the same straight line with the ring center lines of the supporting semicircular ring 8 and the sliding semicircular ring 9, so that the two are matched to achieve the guiding effect when the gear 15 is transmitted, which belongs to an extended implementation method known to ordinary technicians in this field.

[0038] The number of the frame support rods 3 is 2. An escape gap 13 is provided between the sliding semicircular ring 9 and the side plate 4.

[0039] The rotation of the gear drives the tooth surface 11 to rotate so that the U-shaped notch 7 includes a state facing the side and a state facing upward. That is, the gear in the present device drives the sliding semicircular ring 9 to slide along the annular outer side surface of the supporting semicircular ring 8 by meshing with the tooth surface 11 on the outside of the sliding semicircular ring 9. When the gear 15 rotates, the sliding semicircular ring 9 also rotates, driving the U-shaped notch 7 inside it to change direction. The state of the U-shaped notch 7 facing upward: when the gear rotates so that the U-shaped notch 7 faces upward, the supporting annular column 10 at the end of the roller 6 is precisely docked with the U-shaped notch 7. At this time, the roller 6 is stably limited and fixed in the device to ensure that no displacement occurs during the winding process. This limited state keeps the roller 6 in a predetermined position, which is suitable for the normal winding operation of the coil.

[0040] The state where the U-shaped notch 7 faces the side: when the gear continues to rotate and the sliding semicircular ring 9 rotates to the point where the U-shaped notch 7 faces the side, the limit is released, and the supporting annular column 10 of the roller 6 is separated from the U-shaped notch 7. At this time, the roller 6 is no longer restricted and can slide freely from the side. The advantage of this design is that the operator can easily remove or replace the roller 6 from the side without complicated disassembly and assembly steps, which greatly simplifies the equipment maintenance and roller 6 replacement process. By driving the rotation of the tooth surface 11 through the gear, the device realizes the automatic switching of the limit and release of the roller 6, which not only ensures the stability during operation, but also facilitates the removal and replacement of the roller 6. This design has a simple structure and is easy to operate, which greatly improves the practicality and production efficiency of the equipment.

[0041] Embodiment 1:

[0042] The utility model discloses an embracing cutting device for a winding machine, which is specifically used in the positioning and cutting process of the roller 6 of the industrial coil winding machine. In traditional coil winding equipment, the positioning of the roller 6 is mainly controlled by the cylinder pressure method. However, in actual production, the cylinder system is easily affected by environmental factors (such as temperature and air pressure fluctuations), resulting in inaccurate positioning. In addition, due to frequent mechanical movement, wear and tear occurs, the equipment life is shortened, and the maintenance cost increases. These problems are particularly prominent when the production line is running at high speed. Therefore, there is an urgent need for a structural design that can effectively solve the problems of positioning accuracy and equipment durability.

[0043] In this embodiment, the device realizes precise positioning and limit control of the roller shaft 6 during the winding process through the coordinated action of the frame 1, the winding roller 2, and the embracing positioning mechanism. Specifically, the frame 1 is composed of two side plates 4 and a plurality of support rods, forming a stable working space 5 to ensure that the winding roller 2 runs smoothly during the winding process. The two ends of the roller shaft 6 are fixed by the embracing positioning mechanism, which is composed of a sliding semicircular ring 9 and a supporting semicircular ring 8. The supporting semicircular ring 8 is fixed on the side plate 4, and the sliding semicircular ring 9 is sleeved on the outside of the supporting semicircular ring 8 and can slide along its annular outer side surface.

[0044] In actual application, when the roller 6 needs to be positioned, the motor 12 drives the gear through the motor shaft, and the gear meshes with the tooth surface 11 on the outer side of the sliding semicircular ring 9, so that the sliding semicircular ring 9 slides radially. When the sliding semicircular ring 9 slides to a specific position, the U-shaped notch 7 inside it cooperates with the supporting annular column 10 at the end of the roller 6 to form a stable limiting state. This method can not only ensure the stable operation of the roller 6 during the winding process, but also avoid the positioning deviation caused by pressure fluctuations or external temperature changes in the cylinder positioning method.

[0045] Through this structural design, the device has the following significant effects during the coiling process:

[0046] 1. Improve positioning accuracy: Compared with the traditional cylinder pressing method, through the mechanical meshing of the gear and the tooth surface 11, the precise limit of the roller shaft 6 is achieved, ensuring the stability during the coiling of the coil. Especially during long-term continuous operation, it can still maintain an efficient positioning effect.

[0047] 2. Extend the equipment life: The design of the sliding semi-circular ring 9 and the supporting semi-circular ring 8 reduces the friction between mechanical components. Compared with the wear caused by the frequent pressing of the cylinder system, the meshing fit in this device greatly reduces the friction loss, thereby extending the service life of the equipment and reducing the maintenance frequency and cost.

[0048] 3. Save space and improve efficiency: Since this device adopts a gear meshing positioning mechanism, compared with the complex pipeline layout of the cylinder system, the structure is more compact, reducing the occupied space of the equipment. Especially in modern factories with limited space, the application of this device makes the production line layout more flexible and further improves the production efficiency.

[0049] 4. Easy to operate: During the operation process, the motor 12 drives the gear to mesh with the tooth surface 11, automatically realizing the limitation and release of the limit of the roller shaft 6, without relying on manual intervention or a complex operating system. At the same time, a protective cover 14 is designed on the top of the device, effectively preventing the operator from accidentally contacting the sliding parts and improving the safety of the equipment.
