Description

Technical Field

[0001] This utility model belongs to the field of cutting roller switching technology, specifically relating to a roll die-cutting roller switching mechanism. Background Technology

[0002] A roll die-cutting roller is a cylindrical roller device used to load, transport, and wind up strip raw materials on a roll die-cutting production line. It is a core mechanical component in the die-cutting process to achieve continuous material processing. Its essential function is to ensure that the strip passes through the die-cutting station at a constant speed and with stable tension through rotational motion and tension control, so as to complete processing actions such as slitting, creasing, and forming.

[0003] However, in actual production, when switching to produce die-cut products of different sizes and thicknesses, it is necessary to change the material rollers of the corresponding specifications. However, the current material roller replacement process still relies on manual operation, which not only requires tedious disassembly and reinstallation of the equipment, but also has problems such as insufficient installation accuracy and time-consuming operation. Due to the lack of an automated switching mechanism, the production process often requires long downtime, which greatly affects production efficiency and makes it difficult to meet the needs of modern manufacturing for efficient and continuous production.

[0004] To address the aforementioned issues, this application proposes a roll die-cutting roller switching mechanism. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a roll die-cutting roller switching mechanism, which has the feature of being able to switch rollers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roll die-cutting roller switching mechanism, comprising a support frame, a first rotating sleeve fixedly connected to the inner wall of the support frame, a controller disposed above the support frame, a brake motor disposed on the left side of the support frame, the power output end of the brake motor being fixedly connected to the left end of the inner rod of the first rotating sleeve, two rotary motors and two sliding slot seats disposed on the right side of the support frame, a sliding frame slidably connected inside each sliding slot seat, an electric push rod disposed inside each sliding slot seat, the telescopic ends of the two electric push rods being fixedly connected to the adjacent sides of the two sliding frames, a second rotating sleeve fixedly connected to the inner wall of each sliding frame, the power output end of each rotary motor being fixedly connected to the left end of the inner rod of the second rotating sleeve, a roller disposed on the right side of each sliding frame, and the outer surface of each roller contacting the inner wall of the inner rod of the second rotating sleeve.

[0009] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the bottom surface of the controller, and the bottom surface of the connecting plate is fixedly connected to the upper surface of the support frame.

[0010] As a preferred embodiment of this utility model, a connecting frame is fixedly connected to the right end of the inner rod of the first rotating sleeve, and the upper and lower surfaces of the connecting frame are respectively fixedly connected to the sides of the two sliding groove seats that are close to each other.

[0011] As a preferred embodiment of this utility model, each of the two rotary motors is fixedly connected to a connecting seat on the side away from each other, and the right side of each connecting seat is fixedly connected to the left side of the sliding frame.

[0012] As a preferred embodiment of this utility model, each of the electric push rods has a fixed ring fixedly connected to its outer surface, and the two fixed rings are respectively fixedly connected to the inner top wall and the inner bottom wall of the two sliding slot seats on opposite sides.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the controller, the equipment can be automatically controlled, and the operating parameters can be precisely adjusted and the start and stop can be controlled. At the same time, the adapter interface design of the second rotating sleeve and the material roller can ensure the quick installation and fixing of material rollers of different specifications. Through the rotary motor, the inner rod of the second rotating sleeve can be driven to rotate in tandem with the material roller, thereby achieving stable feeding. Then, the brake motor can drive the sliding groove seat and sliding frame and other components to rotate as a whole, completing the rapid switching of the old and new material rollers. With the help of the electric push rod, the sliding frame is pushed to slide flexibly along the sliding groove seat, and the rotary motor, the second rotating sleeve and the material roller are simultaneously adjusted to the appropriate operating height.

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. Example

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a roll die-cutting roller switching mechanism, including a support frame 1, a first rotating sleeve 8 fixedly connected to the inner wall of the support frame 1, a controller 5 provided above the support frame 1, a brake motor 4 provided on the left side of the support frame 1, the power output end of the brake motor 4 fixedly connected to the left end of the inner rod of the first rotating sleeve 8, two rotary motors 10 and two sliding slot seats 7 respectively provided on the right side of the support frame 1, a sliding frame 12 slidably connected inside each sliding slot seat 7, an electric push rod 14 provided inside each sliding slot seat 7, the telescopic ends of the two electric push rods 14 fixedly connected to the side of the two sliding frames 12 that are close to each other, a second rotating sleeve 17 fixedly connected to the inner wall of each sliding frame 12, the power output end of each rotary motor 10 fixedly connected to the left end of the inner rod of the second rotating sleeve 17, a material roller 13 provided on the right side of each sliding frame 12, and the outer surface of each material roller 13 in contact with the inner wall of the inner rod of the second rotating sleeve 17;

[0024] In this embodiment, both the first rotating sleeve 8 and the second rotating sleeve 17 adopt a double-rod nested design. The outer rod is rigidly connected to the support frame 1 through the sliding frame 12 to form a stable support structure. At the same time, the inner rod cooperates with the outer rod through a high-precision bearing, so as to obtain support while maintaining flexible rotation characteristics. This design enables the inner rod to efficiently transmit torque under the drive of the brake motor 4 or the rotary motor 10, so as to drive the connecting frame 9, the sliding groove seat 7, the sliding frame 12, the material roller 13 and other related components to achieve precise rotation and displacement, ensuring the stability and reliability of power transmission.

[0025] Specifically, two sets of fixing pins 2 are provided on the upper part of the support frame 1. The bottom end of each fixing pin 2 passes through the support frame 1 and extends to the bottom of the support frame 1. In this embodiment, the support frame 1 can be passed through and fixed by the fixing pins 2, so that the support frame 1 can be used stably.

[0026] Specifically, a fixed base 3 is fixedly connected to the bottom surface of the brake motor 4. The right side of the fixed base 3 is fixedly connected to the left side of the support frame 1. In this embodiment, the brake motor 4 can be fixed by the fixed base 3. At the same time, the brake motor 4 is a special motor that integrates an electromagnetic braking system. By adding an electromagnetic brake to the rear cover of the motor, the motor can achieve the function of rapid braking when the power is cut off.

[0027] Specifically, a connecting plate 6 is fixedly connected to the bottom surface of the controller 5, and the bottom surface of the connecting plate 6 is fixedly connected to the upper surface of the support frame 1. In this embodiment, the controller 5 can be fixed by the connecting plate 6. At the same time, the controller 5 is a PLC programmable logic controller, which is a digital computing and operating electronic system designed for industrial automation control scenarios. It stores instructions through a programmable memory, performs functions such as logical operations, sequential control, timing, counting and arithmetic operations, and controls various machines or production processes through digital or analog input / output interfaces. It is one of the core control devices of modern industrial automation.

[0028] Specifically, a connecting frame 9 is fixedly connected to the right end of the inner rod of the first rotating sleeve 8. The upper surface and the bottom surface of the connecting frame 9 are respectively fixedly connected to the side of the two sliding slot seats 7 that are close to each other. In this embodiment, the connecting frame 9 can fix the sliding slot seats 7, thereby driving the two sliding slot seats 7 to rotate.

[0029] Specifically, each of the two rotating motors 10 has a connecting seat 11 fixedly connected to one of their opposite sides. The right side of each connecting seat 11 is fixedly connected to the left side of the sliding frame 12. In this embodiment, the rotating motor 10 can be fixed by the connecting seat 11. The rotating motor 10 is a rotating electromechanical device that converts electrical energy into mechanical energy through electromagnetic induction or other physical effects.

[0030] Specifically, each electric push rod 14 has a fixed ring 15 fixedly connected to its outer surface. The two fixed rings 15 are respectively fixedly connected to the inner top wall and inner bottom wall of the two sliding slot seats 7 on opposite sides. In this embodiment, the electric push rod 14 can be fixed into the sliding slot seat 7 by means of the fixed rings 15, thereby making the electric push rod 14 firm.

[0031] Specifically, each of the second rotating sleeves 17 has a threaded pin 16 on its outer surface. The ends of the two threaded pins 16 that are far apart from each other are threaded through the inner rod of the second rotating sleeve 17 and the material roller 13 and extend to the outer side of the second rotating sleeve 17. In this embodiment, the material roller 13 can be fixed to the inner rod of the second rotating sleeve 17 by means of the threaded pin 16, so that the material roller 13 can be installed in the second rotating sleeve 17 for use.

[0032] The working principle and usage process of this utility model are as follows: First, the support frame 1 is securely installed at the designated station on the die-cutting production line using the fixed pin 2. Then, the switching parameters for the material roller 13 are preset on the human-machine interface of the controller 5. When the material roller 13 needs to be replaced, the controller 5 issues a command, energizing the brake motor 4. Its output shaft drives the inner rod of the first rotating sleeve 8 to rotate, which in turn drives the two sliding slot seats 7 to rotate synchronously via the connecting frame 9, causing the spare material roller 13 to move to the working position. The built-in electromagnetic brake of the brake motor 4 immediately brakes upon reaching the working position to ensure positioning accuracy. Subsequently, the electric push rod 14 extends and retracts according to the preset parameters, pushing the sliding frame 12 to slide up and down along the guide rail of the sliding slot seat 7, thereby adjusting the second rotating sleeve 17 and the material roller 13 to the working position. The height is matched with the die-cutting station. Then, the rotary motor 10 starts and drives the inner rod of the second rotating sleeve 17 to rotate. The torque is transmitted through the cooperation between the inner rod and the outer surface of the material roller 13. At the same time, the threaded pin 16 passes through the threaded hole of the inner rod and the material roller 13 to fix the material roller 13. Finally, the new material roller 13 starts to be fed under the drive of the rotary motor 10. The controller 5 dynamically adjusts the speed of the rotary motor 10 through the built-in PLC program to ensure that the material strip passes through the die-cutting station with constant tension. When the old material roller 13 is exhausted or it is necessary to switch to different specifications of products, the above process is repeated. The dual-station design realizes non-stop switching. The braking function of the brake motor 4 can lock the rotating parts instantly when the power is cut off. The modular structure design greatly shortens the replacement time of the material roller 13.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
