Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin feeding machine technology, specifically to a feeding machine shearing mechanism. Background Technology

[0002] The existing sanitary napkin feeding machine's tweezer mechanism typically consists of a support base, servo motor, bushing, tweezer shaft, and tweezer plate. In this structure, the tweezer shaft is only supported at one end of the motor shaft, resulting in eccentric stress. This causes the motor shaft to directly bear the eccentric force, producing a whistling sound, affecting the motor's response time, and reducing the motor's lifespan with prolonged use. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a feeder mechanism for a feeder, which solves motor-related problems caused by eccentric force in existing feeder mechanisms, thereby improving motor response speed and service life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A material handling machine's lever mechanism includes a support base, a servo motor, a bushing, a lever shaft, and levers, as well as a fixing plate and a universal bearing seat. The support base supports the lever mechanism. The servo motor is mounted on the support base and provides power for the rotation of the lever shaft. The bushing is sleeved on the lever shaft, and one end of the lever shaft is connected to the motor shaft of the servo motor. The fixing plate is mounted on the other end of the support base, and the universal bearing seat is mounted on the fixing plate. The lever shaft passes through the universal bearing seat, providing support on both sides of the lever shaft.

[0006] In a further preferred embodiment, the lever shaft passes through a pre-drilled hole in the suction cavity and cooperates with the suction cavity. When the product is carried forward by the suction cavity, the lever shaft rotates to drive the paddle downward, guiding the product to the next work station. After the paddle is finished, the paddle automatically returns to its original position.

[0007] Furthermore, the universal bearing housing is used to support the lever shaft and can prevent the motor shaft from being concentric with itself within a certain range, thereby reducing the force directly experienced by the motor shaft;

[0008] Furthermore, the fixing plate and the support base are fixed together by bolts, and the bushing and the support base are interference fit.

[0009] This utility model has the following beneficial effects:

[0010] By adding a fixing plate and installing a universal bearing housing at the other end of the support base, the lever shaft is supported on both sides, improving the force on the lever and reducing the eccentric torque. Compared with the original lever mechanism, the lever is subjected to more uniform force, which can improve the response speed of the motor, reduce the eccentric torque on the motor shaft, and improve the service life of the motor. By utilizing the function of the universal bearing housing, the motor shaft can be non-concentric with itself within a certain range. This floating can reduce the force directly on the motor shaft, thereby better protecting the servo motor. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the overall structure of the feeder mechanism of the present invention. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and relevant knowledge. Obviously, the described applications are only some embodiments of the present invention, and not all embodiments.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] Reference Figure 1 As shown, a material handling machine's lever mechanism includes a support base 1, a servo motor 2, a bushing 3, a lever shaft 4, and a lever 5. It also includes a fixing plate 6 and a universal bearing seat 7. The support base 1 supports the lever mechanism. The servo motor 2 is mounted on the support base 1 and provides power for the rotation of the lever shaft. The bushing 3 is sleeved on the lever shaft 4, and one end of the lever shaft 4 is connected to the motor shaft of the servo motor 2. The fixing plate 6 is mounted on the other end of the support base 1, and the universal bearing seat 7 is mounted on the fixing plate 6. The lever shaft 4 passes through the universal bearing seat 7, so that both sides of the lever shaft are supported.

[0015] Specifically, the support base 1 is fixedly installed at the corresponding position on the feeder to support the entire lever mechanism, which is equipped with levers 5. The servo motor 2 is installed at a suitable position on the support base 1 to provide power for the rotation of the lever shaft 4. A fixing plate 6 is installed at the other end of the support base, and the connection can be ensured to be firm by means of bolts or other methods. Then, the universal bearing seat 7 is installed on the fixing plate 6.

[0016] One end of the extended lever shaft 4 is connected to the motor shaft of the servo motor, and the other end passes through the universal bearing seat. The bushing is fitted onto the corresponding part of the lever shaft, and the bushing and the support seat are interference-fitted to ensure a stable connection. At this time, the lever shaft is supported on both sides, improving the stress distribution.

[0017] Working process: When the product moves forward through the suction chamber, the servo motor starts, driving the lever shaft to rotate. The lever shaft then moves the paddle downwards, guiding the product to the next workstation. After the paddle is finished, it automatically returns to its original position. Throughout the entire process, due to the presence of the universal bearing housing, the motor shaft can be slightly misaligned within a certain range. When machining or installation errors cause the lever shaft to become misaligned, this floating mechanism reduces the direct force on the motor shaft, preventing issues such as excessive eccentric force that could cause whistling. It also improves the motor's response speed and extends its service life.

[0018] Although some embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, and all such changes and alterations should fall within the scope of the present invention.
