Description

Technical Field

[0001] The present invention relates to the technical field of winders, and in particular to a three-in-one automatic winder. Background Art

[0002] In the production process of film blowing machines, the winding process is a key step to ensure the quality of the finished film and production efficiency. At present, the winding devices of most film blowing machines on the market mainly use an air shaft and a large rubber roller to carry out the winding work. The air shaft is passively rotated by friction with the large rubber roller to complete the winding of the film (such as a film center winder disclosed in application number CN2023115362926). However, this traditional winding method has obvious technical defects. On the one hand, the pressure between the large rubber roller and the air shaft is adjusted, and it cannot be flexibly adjusted according to the film of different materials and thicknesses. This can easily cause the film to be wound too loose or too tight, affecting the winding effect and the quality of the finished film; on the other hand, the air shaft can only rely on the friction of the large rubber roller to rotate passively, and lacks an active rotation function, which makes the winding process single and difficult to adapt to diversified production needs. In addition, the traditional winding device relies mostly on manual work in the upper and lower roll operations of the air shaft, which not only increases labor intensity and reduces production efficiency, but also poses certain safety hazards. Therefore, the development of a winding device with multiple winding modes, adjustable pressure and automatic upper and lower rolling of the air shaft is of great significance to improving the technical level and production efficiency of the winding link of the film blowing machine.

[0008] Furthermore, there are two clutch mechanisms, which are respectively provided at both ends of the bracket for docking with both ends of the inflatable shaft;

[0010] The third driving assembly is arranged on one end of the bracket, and includes a driving motor and an output pulley drivingly connected to the driving motor, and the output pulley is fixed on the docking shaft.

[0011] Furthermore, the interlocking structure includes a convex step on the end of the docking shaft and an interlocking groove on the end of the inflatable shaft, and the interlocking groove and the convex step are interlocked with each other to realize the connection between the docking shaft and the inflatable shaft.

[0012] Furthermore, roller seats are provided on both ends of the bracket, and telescopic pins, telescopic cylinders, rotary lock blocks and driving components are provided on the roller seats. A connection port is formed between the telescopic pins and the rotary lock blocks for rotational connection with both ends of the inflatable shaft.

[0013] 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;

[0014] The rotary locking block is rotatably connected to the rotary groove on the roller seat via a pin shaft, and the driving component drives the rotary locking block to rotate around the pin shaft, so as to control the rotary locking block to partially protrude from the connection port to prevent the inflatable shaft from detaching from the connection port, or to control the rotary locking block to partially retract from the connection port into the rotary groove to open the opening above the connection port.

[0015] Furthermore, a travel arc groove is provided on the rotating locking block, a limit pin is provided in the rotating groove, and the limit pin passes through the travel arc groove.

[0016] Furthermore, the lower roll assembly includes a rotating shaft rotatably connected to one end of the bracket, a unloading arm fixed on both ends of the rotating shaft, and a lower roll cylinder for driving the unloading arm to rotate, a lower roll support portion is provided on one side of the middle part of the unloading arm, and a guiding slope for guiding the inflatable shaft to the lower roll support portion is provided on one side of the vertical plate of the frame and one side of the roller seat.

[0021] The beneficial effects of the present invention are:

[0022] 1. In winding mode, the clutch mechanism in the roller clutch assembly enables switching between connecting and disconnecting the air shaft power. When the clutch is disconnected from the power, the air shaft can rewind by friction with the large rubber roller. When connected to the power, the air shaft can achieve active rewinding. It can also achieve mixed rewinding by combining friction with the large rubber roller and power, flexibly adapting to the winding needs of films of different materials and thicknesses, effectively improving rewinding quality and efficiency.

[0023] 2. Regarding pressure regulation, the ejection mechanism drives the bracket to slide, thereby adjusting the distance between the large rubber roller and the air shaft, allowing the pressure between them to be precisely adjusted according to actual production needs. This design avoids the problem of film winding being too loose or too tight due to improper pressure, ensuring the flatness and integrity of the finished film, and improving product quality.

[0024] 3. In automated production, the unwinding assembly automatically unloads the wound inflatable shaft, while the upper roller assembly automatically rolls the empty inflatable shaft onto the transfer slot of the transfer plate, replacing manual loading. This not only reduces labor intensity and labor costs, but also avoids the potential safety hazards of manual operation, significantly improving the degree of automation and production efficiency, and enhancing the practicality and market competitiveness of the equipment.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0036] The invention provides a three-in-one automatic winding machine.

[0037] In this embodiment, referring to Figure 1-7 The three-in-one automatic winder includes a frame 1, a large rubber roller 2 arranged on the frame 1, a turnover 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 1, a transfer cylinder 5 for driving the transfer plate 4 to rotate, a first drive assembly 6 for driving the turnover plate to rotate relative to the large rubber roller, and a second drive assembly 7 for driving the large rubber roller to rotate, and also includes a roller clutch assembly, a lower winding assembly, and an upper roller assembly;

[0038] The roller clutch assembly includes an inflatable shaft 8, a clutch mechanism, a third drive assembly, a bracket 9, and an ejection mechanism 10. Both ends of the inflatable shaft are rotatably connected to the bracket 9. The clutch mechanism is used to connect and disconnect the drive between the third drive assembly and the inflatable shaft. The bracket is slidably arranged on the frame, and the ejection mechanism drives the bracket to move along the frame guide rail to move the inflatable shaft closer to or away from the large rubber roller.

[0039] The unwinding assembly is used to automatically unwind the rolled inflatable shaft;

[0040] The upper roller assembly is used to automatically roll the empty inflatable shaft to the transfer slot 11 on the transfer plate.

[0041] In the above technical solution, based on the traditional frame, large rubber roller and other structures, a roller clutch assembly, a lower winding assembly and an upper roller assembly are newly added. The roller clutch assembly controls the power connection between the third drive assembly and the air shaft through the clutch mechanism, and the ejection mechanism drives the bracket to slide and adjust the distance between the air shaft and the large rubber roller; the lower winding assembly is responsible for unloading the air shaft after winding is completed; and the upper roller assembly automatically rolls up the empty air shaft. The various components work together to achieve a variety of winding modes, and friction winding, active winding or mixed winding can be selected according to production needs; the pressure between the large rubber roller and the air shaft can be flexibly adjusted to ensure winding quality; the upper and lower rolling of the air shaft are automatically completed, reducing labor costs, improving production efficiency and safety, and significantly enhancing the practicality and competitiveness of the equipment.

[0042] As shown in the attached figure of the specification, the ejection mechanism can use a cylinder to push 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 to the discharging direction to discharge the material, and then equips the unwinding assembly to complete automatic unloading.

[0043] The bracket and the rack are connected via a slide rail and slider assembly.

[0044] Specifically, there are two clutch mechanisms, which are respectively provided at both ends of the bracket for docking with both ends of the inflatable shaft;

[0045] The clutch mechanism includes a bearing seat 12, a clutch cylinder 13, and a docking shaft 14 connected to the output end of the clutch cylinder 13. The docking shaft and the bearing seat are rotatably matched through bearings and can slide axially. The end of the docking shaft and both ends of the inflatable shaft are provided with interlocking structures.

[0046] The third driving assembly is provided on one end of the bracket, and includes a driving motor 15 and an output pulley 16 drivingly connected to the driving motor 15 , wherein the output pulley 16 is fixed on the docking shaft.

[0047] In this embodiment, a clutch mechanism is provided at each end of the bracket. A clutch cylinder in the clutch mechanism pushes the docking shaft, achieving power connection and disconnection through the interlocking structure between the docking shaft and the end of the inflatable shaft. The drive motor of the third drive assembly drives the docking shaft via the output pulley, which in turn drives the inflatable shaft to rotate.

[0048] Specifically, the interlocking structure includes a convex step 17 on the end of the docking shaft and an interlocking groove 18 on the end of the inflatable shaft. The interlocking groove 18 and the convex step are interlocked with each other to realize the connection between the docking shaft and the inflatable shaft.

[0049] In this embodiment, the convex step at the end of the docking shaft engages with the interlocking groove at the end of the inflatable shaft, forming a simple yet effective mechanical connection. When the clutch cylinder pushes the docking shaft, the convex step engages the interlocking groove, transferring power from the docking shaft to the inflatable shaft. During separation, the convex step disengages from the interlocking groove, interrupting power transmission. The interlocking structure is simple and reliable, enabling quick and easy connection and disconnection between the docking shaft and the inflatable shaft.

[0050] Specifically, roller seats 19 are provided at both ends of the bracket, and telescopic pins 20, telescopic cylinders 21, rotary lock blocks 22 and driving components are provided on the roller seats 19. A connection port 24 is formed between the telescopic pins and the rotary lock blocks for rotational connection with both ends of the inflatable shaft.

[0051] The telescopic pin is connected to the through hole 25 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;

[0052] The rotary locking block is rotatably connected to the rotary groove 26 on the roller seat via a pin shaft, and the driving component drives the rotary locking block to rotate around the pin shaft, so as to control the rotary locking block to partially protrude from the connection port to prevent the inflatable shaft from detaching from the connection port, or to control the rotary locking block to partially retract from the connection port into the rotary groove to open the opening above the connection port.

[0053] In this embodiment, telescopic pins on either side of the roller seat move up and down along the through-holes, driven by a telescopic cylinder. A rotary locking block rotates around the pins via a drive component (not shown; a cylinder could be used instead). When the inflatable shaft is placed in the connector, the telescopic pins rise, and the rotary locking block rotates and protrudes from the connector, locking the shaft within. To remove the shaft, the rotary locking block retracts, opening the connector.

[0054] In addition, when the winding is completed and the material is discharged, the telescopic pin drops, and the wound air shaft can be rolled into the lower winding support part for unloading by using the stud and the guide slope.

[0055] Specifically, a travel arc groove 27 is provided on the rotary lock block, and a limit pin 28 is provided in the rotary groove, and the limit pin passes through the travel arc groove.

[0056] In this embodiment, the travel arc groove on the rotary lock block cooperates with a stop pin within the rotation slot, limiting the rotation angle and travel of the rotary lock block. When the driving component rotates the rotary lock block, the travel arc groove slides along the stop pin, ensuring that the rotary lock block moves along a predetermined trajectory and angle, accurately controlling its movement toward or away from the connection port.

[0057] Specifically, the lower roll assembly includes a rotating shaft 29 rotatably connected to one end of the bracket, a discharge arm 30 fixed to both ends of the rotating shaft 29, and a lower roll cylinder 31 for driving the discharge arm to rotate. A lower roll support portion 32 is provided on one side of the middle part of the discharge arm, and a guide slope 34 for guiding the inflatable shaft to the lower roll support portion is provided on one side of the vertical plate 33 of the frame and one side of the roller seat.

[0058] In this embodiment, the unwinding cylinder drives the rotating shaft, which in turn rotates the unloading arm. During this rotation, the unwinding support in the middle of the unloading arm receives the inflatable shaft, which slides down from the frame uprights and the guide ramps on the roller seat, completing the unwinding operation. The guide ramps act as a guide, allowing the inflatable shaft to slide smoothly onto the unwinding support.

[0059] The above structure realizes automatic unloading of the wound inflatable shaft without manual intervention, thus reducing labor intensity. The guiding inclined surface cooperates with the unwinding support part to ensure smooth and accurate unloading of the inflatable shaft, thus preventing the inflatable shaft from falling or being damaged, and improving production efficiency and reliability of equipment operation.

[0060] Specifically, a loading support portion 35 is provided on the top of the discharge arm.

[0061] In this embodiment, the loading support is an overall L-shaped structure. The loading support at the top of the discharge arm temporarily supports the empty inflatable shaft while it is being loaded onto the roller. During the unloading process, the discharge arm rotates toward the bottom to unload the material. After unloading, the cylinder shaft of the hole can be placed on the loading support. Then, the discharge arm rotates to lift the cylinder shaft of the hole, and the upper roller assembly cooperates to complete the transfer of the inflatable shaft from its storage position to the transfer slot of the transfer plate. The loading support provides an intermediate transition support point for the transfer of the inflatable shaft and also serves to assist in loading.

[0062] Specifically, the upper roller assembly includes a frame 36 fixed on the vertical plate of the bracket, a slide 37 slidably set on the frame 36 through a slide rail slider assembly, a mechanical gripper 38 fixed on the slide 37, and a driving mechanism for driving the mechanical gripper 38 to move.

[0063] In this embodiment, a drive mechanism drives a slide plate to slide on the frame via a slide rail and slider assembly. A mechanical gripper on the slide plate is used to grasp the inflatable shaft. A transmission motor in the drive mechanism rotates a drive rod. Drive gears at each end of the drive rod engage with a drive rack on the frame, converting the motor's rotational motion into linear motion of the slide plate. This movement of the mechanical gripper allows the empty inflatable shaft to be grasped from the loading support and transferred to the transfer slot on the transfer plate.

[0064] After moving to the transfer trough, the transfer plate is rotated to make the inflatable shaft roll into the slot of the flip plate, and finally the flip plate is rotated to make the inflatable shaft roll down the slide connection port to achieve the final upper roller. This process is existing technology and will not be described in detail.

[0065] Specifically, the driving mechanism includes a transmission motor 39 fixed on the skateboard, a driving rod 40 drivingly connected to the transmission motor 39, a driving gear 42 fixed on both ends of the driving rod 40, and a driving rack 42 fixed on the frame, and the driving gear is engaged with the driving rack for transmission.

[0066] In this embodiment, the drive rod rotates, and the drive gears at each end of the drive rod mesh with the drive rack fixed to the frame. Based on the rack-and-pinion transmission principle, the rotational motion of the drive gear is converted into linear motion of the slide and the mechanical gripper. By controlling the speed and direction of the motor, the movement speed and position of the mechanical gripper can be precisely controlled.

[0067] Specifically, the mechanical gripper includes a shell 43, a lifting cylinder 44 fixed on the shell 43, a main clamping arm 45 connected to the output end of the lifting cylinder 44, a movable clamping arm 46 hinged to the main clamping arm 45, and a clamping cylinder 47 fixed on the main clamping arm, the output end of the clamping cylinder is connected to the movable clamping arm, and the ends of the main clamping arm and the movable clamping arm are provided with arc-shaped clamping grooves 48.

[0068] In this embodiment, the lifting cylinder drives the main clamping arm up and down to lift the inflatable shaft. The clamping cylinder drives the movable clamping arm to rotate around its hinge point with the main clamping arm, and the main and movable clamping arms work together to clamp or release the inflatable shaft. These cylinders work together to ensure the mechanical gripper can stably grasp, lift, and place the inflatable shaft.

[0069] Technical personnel should note: Although the present invention has been described according to the above specific implementation methods, the concept of the present invention is not limited to this invention. Any modification using the concept of the present invention will be included in the scope of protection of this patent right.
