Description

Technical Field

[0001] This utility model relates to the field of automatic winding machine technology, and specifically to a roller clutch mechanism for an automatic winding machine. Background Technology

[0002] In industrial production, automatic winding machines are key pieces of equipment, widely used in the winding processes of materials such as film and paper. Their performance directly affects the winding quality and production efficiency of the products. Among the many components of an automatic winding machine, the roller clutch mechanism plays a crucial role, determining the stability and flexibility of the winding process.

[0003] In existing blown film machines, the air shaft typically rotates passively through friction with the large rubber roller during the winding process. However, this traditional winding method has several drawbacks. Firstly, the pressure between the large rubber roller and the air shaft is not adjustable, making it impossible to optimize for different material properties and winding requirements. This can easily lead to uneven winding tension, affecting product quality. Secondly, the air shaft lacks an active rotation function, relying solely on friction for winding, resulting in low winding efficiency. This makes it difficult to meet production requirements when handling special materials or high-speed winding. Therefore, there is an urgent need for a roller clutch mechanism that can overcome these shortcomings, enabling diverse winding modes and adjustable pressure, to improve the overall performance of automatic winding machines. Utility Model Content

[0004] To address the shortcomings in the prior art, this utility model provides a roller clutch mechanism for an automatic winding machine.

[0005] The technical solution adopted by this utility model is: a roller clutch mechanism for an automatic winding machine, including a frame, a large rubber roller mounted on the frame, a flipping plate rotatably connected to both ends of the large rubber roller, a transfer plate rotatably connected to both sides of the frame, a transfer cylinder for driving the transfer plate to rotate, a first drive assembly for driving the flipping plate to rotate relative to the large rubber roller, and a second drive assembly for driving the large rubber roller to rotate. It also includes a roller clutch assembly, which includes an air shaft, a clutch mechanism, a third drive assembly, a bracket, and a push-out mechanism. The air shaft is rotatably connected to the bracket at both ends. The clutch mechanism is used to connect and disconnect the drive between the third drive assembly and the air shaft. The bracket is slidably mounted on the frame. The push-out mechanism drives the bracket to move along the frame guide rail, causing the air shaft to move closer to or further away from the large rubber roller.

[0006] Furthermore, there are two clutch mechanisms, which are respectively located at both ends of the bracket for docking with both ends of the air shaft;

[0007] The clutch mechanism includes a bearing housing, a clutch cylinder, and a docking shaft connected to the output end of the clutch cylinder. The docking shaft and the bearing housing are rotated together by bearings and can slide along the axial direction. Interconnected fitting structures are provided on the end of the docking shaft and both ends of the air shaft.

[0008] Furthermore, the third drive assembly is disposed on one end of the bracket, and includes a drive motor and an output pulley connected to the drive motor, wherein the output pulley is fixed on the docking shaft.

[0009] Furthermore, the fitting structure includes a raised step on the end of the docking shaft and a fitting groove on the end of the air expansion shaft. The fitting groove and the raised step fit together to achieve the connection between the docking shaft and the air expansion shaft.

[0010] Furthermore, roller seats are provided at both ends of the bracket, and telescopic pins, telescopic cylinders, rotary locking blocks and driving components are provided on the roller seats. The telescopic pins and rotary locking blocks form a connection port for rotatable connection with both ends of the air expansion shaft.

[0011] The telescopic pin is connected to the through hole of the roller seat, and the telescopic cylinder is connected to the telescopic pin to drive the telescopic pin to move up and down along the through hole.

[0012] The rotating locking block is rotatably connected to the rotating groove on the roller seat via a pin. The driving component drives the rotating locking block to rotate around the pin, which is used to control the rotating locking block to protrude from the connection port to prevent the air shaft from disengaging from the connection port, or to control the rotating locking block to retract from the connection port into the rotating groove to open the opening above the connection port.

[0013] Furthermore, the rotating locking block is provided with a travel arc groove, and a limit pin is provided in the rotating groove, the limit pin passing through the travel arc groove.

[0014] The beneficial effects of this utility model are:

[0015] First, by setting up a roller clutch assembly, the clutch mechanism can connect and disconnect the drive between the third drive assembly and the air shaft, enabling the air shaft to have diverse winding modes. When the clutch is disengaged, the air shaft can rely on the friction of the large rubber roller for winding, meeting the needs of specific working conditions; when the power is engaged, the air shaft can achieve active winding, greatly improving winding efficiency; it can also utilize the friction of the large rubber roller in combination with power to achieve mixed winding, flexibly responding to the winding requirements of different materials, significantly enhancing the applicability and versatility of the equipment.

[0016] Second, the push-out mechanism drives the support to move along the frame guide rail, which can precisely adjust the distance between the large rubber roller and the air expansion shaft, thereby flexibly adjusting the pressure between them. This adjustable pressure design can be tailored to the thickness, toughness, and other characteristics of the material, effectively avoiding uneven tension during winding, ensuring winding quality, reducing the defect rate, and is especially suitable for production scenarios with high requirements for winding quality.

[0017] Third, the components of the roller clutch mechanism work together in a compact and reasonable manner. While realizing diversified winding modes and pressure regulation functions, it improves the overall stability and reliability of the automatic winding machine, reduces equipment maintenance costs, and helps improve the company's production efficiency and market competitiveness.

[0018] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] This utility model provides a roller clutch mechanism for an automatic winding machine.

[0028] In this embodiment, refer to Figure 1-5 The automatic winding machine's roller clutch mechanism includes a frame 1, a large rubber roller 2 mounted on the frame 1, a flipping plate 3 rotatably connected to both ends of the large rubber roller 2, a transfer plate 4 rotatably connected to both sides of the frame, a transfer cylinder 5 for driving the transfer plate to rotate, a first drive assembly 6 for driving the flipping plate to rotate relative to the large rubber roller, and a second drive assembly 7 for driving the large rubber roller to rotate. It also includes a roller clutch assembly, which includes an air shaft 8, a clutch mechanism, a third drive assembly, a bracket 9, and a push-out mechanism 10. The air shaft is rotatably connected to the bracket at both ends. The clutch mechanism is used to connect and disconnect the drive between the third drive assembly and the air shaft. The bracket is slidably mounted on the frame. The push-out mechanism drives the bracket to move along the frame guide rail, causing the air shaft to move closer to or further away from the large rubber roller.

[0029] In the above technical solution, the transfer cylinder drives the transfer plate to rotate, the first drive assembly drives the flipping plate to rotate relative to the large rubber roller, and the second drive assembly drives the large rubber roller to rotate. In the roller clutch assembly, the air shaft is mounted on the frame via a bracket, and the clutch mechanism can control the on / off connection between the third drive assembly and the air shaft. The ejection mechanism moves along the frame guide rail via the drive bracket (the bracket and the frame slide together via a slide rail slider) to adjust the distance between the air shaft and the large rubber roller.

[0030] It achieves diversified winding modes, allowing users to choose friction winding, active winding, or hybrid winding according to production needs; it can flexibly adjust the pressure between the large rubber roller and the air shaft, adapting to the winding requirements of different materials and ensuring winding quality and equipment applicability.

[0031] As shown in the attached diagram of the instruction manual, the ejection mechanism can be a cylinder that pushes the bracket to slide along the frame. The ejection mechanism can adjust the distance and pressure between the air shaft and the large rubber roller. At the same time, it also pushes the cylinder axis after winding in the discharge direction to discharge the material. It is equipped with a rear unwinding assembly to facilitate subsequent automatic unloading.

[0032] Specifically, there are two clutch mechanisms, which are respectively located at both ends of the bracket for docking with both ends of the air shaft;

[0033] The clutch mechanism includes a bearing housing 11, a clutch cylinder 12, and a docking shaft 13 connected to the output end of the clutch cylinder. The docking shaft 13 and the bearing housing are rotated together by bearings and can slide along the axial direction. Interconnected fitting structures are provided on the end of the docking shaft and both ends of the air shaft. The third drive assembly is located on one end of the bracket and includes a drive motor 14 and an output pulley 15 driven by the drive motor 14. The output pulley is fixed on the docking shaft.

[0034] In this embodiment, a clutch mechanism is provided at each end of the bracket. The clutch cylinder in the clutch mechanism pushes the docking shaft, and the power connection or disconnection is achieved through the fitting structure of the docking shaft and the end of the air expansion shaft. The drive motor of the third drive assembly drives the docking shaft to rotate through the output pulley, thereby driving the air expansion shaft to rotate.

[0035] Specifically, the fitting structure includes a raised step 16 on the end of the docking shaft and a fitting groove 17 on the end of the air expansion shaft. The fitting groove 17 and the raised step 16 fit together to achieve the connection between the docking shaft and the air expansion shaft.

[0036] In this embodiment, the raised step at the end of the docking shaft and the fitting groove at the end of the air expansion shaft engage with each other, forming a simple yet effective mechanical connection structure. When the clutch cylinder pushes the docking shaft, the raised step engages with the fitting groove, realizing the transmission of power from the docking shaft to the air expansion shaft; when disengaged, the raised step disengages from the fitting groove, interrupting the power transmission. The fitting structure design is simple and reliable, enabling quick connection and disconnection of the docking shaft and the air expansion shaft, and is easy to operate.

[0037] Specifically, roller seats 18 are provided at both ends of the bracket, and telescopic pins 19, telescopic cylinders 20, rotating locking blocks 21 and driving components are provided on the roller seats 18. A connection port 22 is formed between the telescopic pins and the rotating locking blocks to be rotatably connected to both ends of the air shaft.

[0038] The telescopic pin is connected to the through hole 23 of the roller seat, and the telescopic cylinder is connected to the telescopic pin to drive the telescopic pin to move up and down along the through hole.

[0039] The rotating locking block is rotatably connected to the rotating groove 24 on the roller seat via a pin. The driving component drives the rotating locking block to rotate around the pin, which is used to control the rotating locking block to protrude from the connection port to prevent the air shaft from disengaging from the connection port, or to control the rotating locking block to retract from the connection port into the rotating groove to open the opening above the connection port.

[0040] In this embodiment, the telescopic pins on both sides of the roller seat move up and down along the through hole under the drive of the telescopic cylinder, and the rotating locking block rotates around the pin shaft through the driving component (not shown in the figure, but can be driven by a cylinder). When the air shaft is placed in the connection port, the telescopic pin rises, and the rotating locking block rotates out of the connection port, locking the air shaft in the connection port; when it is necessary to disassemble the air shaft, the rotating locking block retracts and opens the connection port.

[0041] Specifically, the rotating locking block is provided with a travel arc groove 25, and a limit pin 26 is provided in the rotating groove, the limit pin 26 passing through the travel arc groove.

[0042] In this embodiment, the travel arc groove on the rotary locking block engages with the limiting pin in the rotary groove, and the limiting pin restricts the rotation angle and travel of the rotary locking block. When the driving component drives the rotary locking block to rotate, the travel arc groove slides along the limiting pin, ensuring that the rotary locking block moves along a predetermined trajectory and angle, and accurately controlling its protrusion or retraction of the connection port.

[0043] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
