Description

Technical Field

[0001] This utility model belongs to the field of needle-punched nonwoven fabric processing technology, specifically relating to a quick disassembly and positioning structure for the stripping plate of a needle-punching machine. Background Technology

[0002] In needle-punched nonwoven fabric processing equipment, the needle-punching machine stripper plate is a key functional component installed in the working area of ​​the needle-punching machine to work with the needles to complete the reinforcement and forming of the fiber web. When the needles puncture the fiber web and rise upwards, the stripper plate peels the fiber web off the needles through its own grid structure, preventing the fiber web from being carried away with the needles and ensuring that the fiber web remains stably on the worktable, thus ensuring the continuity of the needle-punching process. At the same time, it also provides support for the fiber web, helping to maintain the shape and positional accuracy of the fiber web during the needle-punching process, indirectly affecting the quality indicators of the nonwoven fabric, such as density, strength, and surface uniformity.

[0003] However, the stripping plate of the needle punching machine has strict requirements for positional accuracy during disassembly and assembly. The traditional installation mode relies too much on manual positioning. Before installation, the relative position of the stripping plate and the frame must be manually calibrated and then tightened. However, this method is prone to positioning deviation. Once the position calibration is inaccurate, the tightened screws must be removed one by one, the positioning must be readjusted and tightened again. The whole process is repetitive and cumbersome, which not only greatly prolongs the installation time, but also makes it impossible to achieve quick disassembly and assembly and accurate positioning of the stripping plate, which seriously affects the maintenance efficiency of the equipment and the continuity of production.

[0004] To address the aforementioned issues, this application proposes a quick assembly and disassembly positioning structure for the stripping plate of a needle punching machine. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a quick disassembly and positioning structure for the stripping plate of a needle punching machine, which enables the quick disassembly and positioning of the stripping plate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly and positioning structure for a stripping plate of a needle punching machine, comprising a base frame, a controller, a stripping plate, and two sliding groove frames respectively arranged on the upper part of the base frame, two sets of electric push rods fixedly connected to the upper surface of the base frame, the telescopic end of each set of electric push rods being fixedly connected to the bottom surface of the sliding groove frame, a threaded rod rotatably connected to the inner wall of each sliding groove frame, a brake motor arranged on the right side of each sliding groove frame, the power output end of each brake motor being fixedly connected to the right end of the threaded rod, a positioning frame slidably connected inside each sliding groove frame, the inner wall of each positioning frame being threadedly connected to the outer surface of the threaded rod, and the upper surfaces of the two positioning frames contacting the bottom surface of the stripping plate.

[0007] As a preferred technical solution of this utility model, two sets of fixing pins are provided on the upper part of the base frame, and the bottom end of each fixing pin passes through the base frame and extends to the bottom of the base frame.

[0008] As a preferred embodiment of this utility model, the bottom surface of the controller is fixedly connected to a mounting plate, and the bottom surface of the mounting plate is fixedly connected to the upper surface of the base frame.

[0009] As a preferred embodiment of this utility model, a reinforcing ring is fixedly connected to the outer surface of each electric push rod, and the bottom surface of each reinforcing ring is fixedly connected to the upper surface of the base frame.

[0010] As a preferred technical solution of this utility model, two sets of connecting pins are provided above the stripping plate, and the bottom end of each set of connecting pins penetrates the stripping plate and extends into the interior of the positioning frame.

[0011] As a preferred embodiment of this utility model, each of the brake motors is fixedly connected to a mounting base on its bottom surface, and the left side of each mounting base is fixedly connected to the right side of the sliding groove frame.

[0012] As a preferred technical solution of this utility model, a protective shell is fixedly connected to the right side of each sliding groove frame, and each protective shell is sleeved on the outside of the brake motor.

[0013] As a preferred embodiment of this utility model, the bottom surface of the base frame is fixedly connected with an anti-slip pad, which is made of rubber.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: By setting a base frame, the entire structure can be installed in a suitable position on the equipment. At the same time, the controller can achieve precise control of the equipment's operating status, conveniently turning the equipment on or off. Utilizing the structural characteristics of the positioning frame, the stripping plate can be installed more conveniently. Then, by using a brake motor to drive the threaded rod to rotate, the positioning frame moves precisely within the sliding groove frame, quickly completing the horizontal positioning of the stripping plate. This replaces the tedious process of manually aligning the screw holes, significantly shortening the positioning time. Furthermore, through the extension and retraction of the electric push rod, the height of the sliding groove frame, positioning frame, and stripping plate can be adjusted, achieving rapid height adjustment of the stripping plate without manual lifting and calibration. The entire positioning process is controlled by the controller, reducing errors from manual positioning and ensuring the relative positional accuracy of the stripping plate and the needles. This effectively solves the problem of repeated disassembly due to inaccurate positioning in traditional installation methods, significantly improving equipment maintenance efficiency and production continuity.

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

[0017] Please see Figure 1-4 This utility model provides the following technical solution: a quick disassembly and positioning structure for a stripping plate of a needle punching machine, including a base frame 1. A controller 2, a stripping plate 10, and two sliding groove frames 6 are respectively arranged on the upper part of the base frame 1. Two sets of electric push rods 7 are fixedly connected to the upper surface of the base frame 1. The telescopic end of each set of electric push rods 7 is fixedly connected to the bottom surface of the sliding groove frame 6. A threaded rod 15 is rotatably connected to the inner wall of each sliding groove frame 6. A brake motor 12 is arranged on the right side of each sliding groove frame 6. The power output end of each brake motor 12 is fixedly connected to the right end of the threaded rod 15. A positioning frame 14 is slidably connected inside each sliding groove frame 6. The inner wall of each positioning frame 14 is threadedly connected to the outer surface of the threaded rod 15. The upper surfaces of the two positioning frames 14 are in contact with the bottom surface of the stripping plate 10.

[0018] In this embodiment, the outer surface of the threaded rod 15 is machined with threads, which cooperate with the internal threads provided on the inner wall of the positioning frame 14. When the brake motor 12 drives the threaded rod 15 to rotate, the positioning frame 14 can be driven to move linearly along the inner wall of the sliding groove frame 6 through the thread transmission action, so as to achieve precise positioning of the stripping plate 10 in the horizontal direction.

[0019] Specifically, two sets of fixing pins 4 are provided on the top of the base frame 1. The bottom end of each fixing pin 4 passes through the base frame 1 and extends to the bottom of the base frame 1. In this embodiment, the base frame 1 can be fixed to a suitable device by means of fixing pins 4, so that the base frame 1 can be used stably.

[0020] Specifically, the bottom surface of the controller 2 is fixedly connected to the mounting plate 3, and the bottom surface of the mounting plate 3 is fixedly connected to the upper surface of the base frame 1. In this embodiment, the controller 2 can be fixed by the mounting plate 3. The controller 2 is a programmable logic controller (PLC), which is a digital computing and operating electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input and output.

[0021] Specifically, each electric push rod 7 has a reinforcing ring 11 fixedly connected to its outer surface, and the bottom surface of each reinforcing ring 11 is fixedly connected to the upper surface of the base frame 1. In this embodiment, the electric push rod 7 can be fixed by the reinforcing ring 11. At the same time, the electric push rod 7 is an electromechanical integrated actuator that converts the rotational motion of the electric motor into linear reciprocating motion. It is mainly composed of components such as a drive motor, reduction gear, screw, nut, push rod and guide sleeve.

[0022] Specifically, two sets of connecting pins 9 are provided above the stripping plate 10. The bottom end of each set of connecting pins 9 passes through the stripping plate 10 and extends into the interior of the positioning frame 14. In this embodiment, the stripping plate 10 can be fixed to the positioning frame 14 by connecting pins 9, and the positioning frame 14 can drive the stripping plate 10 to move.

[0023] Specifically, each brake motor 12 has a fixed base 13 fixedly connected to its bottom surface, and the left side of each fixed base 13 is fixedly connected to the right side of the sliding groove frame 6. In this embodiment, the brake motor 12 can be fixed by the fixed base 13. At the same time, the brake motor 12 is a drive motor that integrates a braking device. While the motor body is running, it can achieve the functions of quick stop and positioning lock through the built-in or external brake.

[0024] Specifically, a protective shell 8 is fixedly connected to the right side of each sliding slot frame 6. Each protective shell 8 is sleeved on the outside of the brake motor 12. In this embodiment, the protective shell 8 can protect the brake motor 12 inside. At the same time, the protective shell 8 is provided with heat dissipation holes to dissipate heat from the brake motor 12.

[0025] Specifically, the bottom surface of the base frame 1 is fixedly connected with an anti-slip pad 5, which is made of rubber. In this embodiment, the rubber material of the anti-slip pad 5 enables the base frame 1 to have stability when fixed.

[0026] The working principle and usage process of this utility model are as follows: First, the base frame 1 is securely installed on the needle punching machine frame using the fixing pin 4, ensuring the anti-slip pad 5 is fully in contact with the contact surface to enhance stability. Next, the controller 2 is powered on for self-testing and loading the preset positioning parameters for the stripping plate 10. The stripping plate 10 is placed on the upper surfaces of the two positioning frames 14 and initially fixed by inserting the connecting pin 9. Then, the target horizontal position parameters are input into the controller 2, which drives the brake motor 12 to rotate the threaded rod 15, causing the positioning frame 14 to move along the inner wall of the sliding groove frame 6. When the target position is reached, the brake motor 12 is de-energized and locked. Finally, the target height parameters are input into the controller 2, controlling the electric push rod 7 to extend and retract, thus moving the stripping plate. The entire stripping plate 10 is raised and lowered. After reaching the target height, the electric push rod 7 locks itself to maintain the position. The controller 2 verifies the position of the stripping plate 10 and automatically fine-tunes it to meet the accuracy requirements. After confirming that the positioning is correct, the needle punching machine starts to run. The controller 2 continuously monitors the status of each component. When the stripping plate 10 needs to be replaced, it is first moved to an easy-to-operate position. The connecting pin 9 is pulled out to remove the old plate. After installing the new plate, the above positioning steps are repeated to quickly complete the replacement without recalibrating the entire system. This utility model realizes the full automation of the stripping plate 10 from installation and positioning to disassembly through electromechanical collaborative control, using the threaded rod 15, nut transmission mechanism and the power-off braking function of the brake motor 12. This greatly shortens the operation time and reduces human error.

[0027] 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.
