Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a material feeding mechanism for a material handling machine. Background Technology

[0002] In the operation of a material handling machine, the pushing mechanism plays a crucial role, and its performance directly affects the machine's efficiency and material handling quality. In existing technologies, the pushing section of a material handling machine typically uses a horizontal servo motor drive and a vertical cylinder drive to achieve the pushing action.

[0003] However, this existing technical solution has significant drawbacks. First, the structure is relatively complex. Since a cylinder is required for longitudinal drive, corresponding pneumatic components such as air pumps, air pipes, and solenoid valves must be included. This not only increases the overall size and weight of the mechanism but also raises the manufacturing cost. Second, in actual use, the cylinder needs frequent adjustments to ensure the accuracy and force of longitudinal material pushing, making operation inconvenient. Furthermore, the cylinder's response speed is relatively slow, which can easily affect the overall working efficiency of the pushing mechanism and fail to meet the production requirements of high-speed material handling.

[0004] In order to solve the above-mentioned problems in the prior art, this utility model proposes a material feeding mechanism for a material handling machine, which aims to simplify the structure, improve speed and ease of operation. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing material feeding mechanisms, such as complex structure, need for additional pneumatic components, inconvenient adjustment, and slow speed, and to provide a material feeding mechanism for a material feeding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A material feeding mechanism for a material feeder is installed on the side of the material receiving section of the material feeder, and includes an upper and lower moving plate, a left and right moving plate, a linear guide rail, a synchronous belt, two servo motors, profiles, and a feeding sheet metal.

[0007] The linear guide includes a left-right linear guide and a vertical linear guide. The vertical linear guide is fixed to the left-right moving plate, which is mounted on the left-right linear guide via a connecting plate. This structure allows the left-right moving plate to move horizontally along the left-right linear guide, while the up-down moving plate can move vertically along the vertical linear guide, thus providing a basis for the two-dimensional motion of the mechanism.

[0008] The left and right moving plates are equipped with pressure rollers. After passing through the pressure rollers, the synchronous belt wraps around the driving synchronous rollers of the two servo motors at both ends, and around the driven synchronous roller at the bottom. It is then connected and fixed to the toothed plate of the upper and lower moving plates at the top. This method of winding the synchronous belt can transmit the power of the two servo motors to the upper and lower moving plates, thereby driving the profile connected to the upper and lower moving plates to move.

[0009] The profile is connected to the upper and lower movable plates, and the pusher sheet metal is set on the profile. When the profile moves, the pusher sheet metal moves accordingly to realize the pusher action.

[0010] By using different combinations of the rotation directions of two servo motors, different movement effects can be achieved, thus realizing the material pushing motion. Specifically, when the left motor is stationary and the right motor rotates clockwise, the profile moves vertically downwards, with the speed and position controlled by the right motor; when the right motor moves counterclockwise, the profile moves vertically upwards. The same vertical movement effect is produced when the left motor rotates while the right motor is stationary. When both the left and right motors rotate clockwise at the same speed, the profile moves horizontally to the right; conversely, when both rotate counterclockwise, the profile moves horizontally to the left. Through program control, these movements can be programmed into a square pushing trajectory required by the production process, i.e., first moving horizontally to the right, then vertically downwards, then horizontally to the left, and finally vertically upwards.

[0011] This utility model has the following beneficial effects: Simpler structure: This utility model adopts dual servo motor drive, which eliminates pneumatic components, reduces the number of parts in the mechanism, simplifies the overall structure, reduces the size and weight of the equipment, and also reduces manufacturing and maintenance costs.

[0012] Faster operating speed: Servo motors have the characteristic of fast response speed. Compared with cylinder drive, they can start, stop and speed change of pushing action faster, improve the working efficiency of the pushing mechanism and meet the production needs of high-speed material handling.

[0013] More precise control: The servo motor can precisely control the speed and direction of rotation. Combined with the precise transmission of the synchronous belt, it can accurately control the movement position and speed of the profile, improve the accuracy and repeatability of the pushing action, and ensure the stability of the material handling quality.

[0014] More convenient to operate: No need to adjust the pneumatic components, various material pushing trajectories can be achieved simply by controlling the servo motor through the program, reducing manual operation steps, lowering the difficulty of operation, and improving the ease of use of the equipment.

[0015] Flexible motion trajectory: By controlling the direction and speed combination of two servo motors through program control, a variety of material pushing trajectories can be realized, not limited to square trajectories, which can adapt to different production process requirements and enhance the versatility and flexibility of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] like Figures 1-3 As shown, the material feeding mechanism of the material feeder in this embodiment is installed on the side of the material receiving part of the material feeder, and is mainly composed of components such as the upper and lower moving plate 1, the left and right moving plate 2, the linear guide rail, the synchronous belt 3, two servo motors 4, the profile 5, the feeding sheet metal 6, the pressure roller 7, the active synchronous roller 8, the driven synchronous roller 9, and the connecting plate 10.

[0019] A toothed plate 11 is provided on one side of the upper and lower moving plate 1 for connecting and fixing to the synchronous belt 3, and for transmitting power and driving the profile to move. When the synchronous belt 3 moves, it drives the upper and lower moving plate to move along the vertical linear guide rail through meshing with the toothed plate 11, thereby realizing the vertical movement of the profile. In other words, the synchronous belt 3 is fixed to the toothed plate 11, thereby driving the upper and lower moving plate 1 to move.

[0020] A vertical linear guide rail 12 is fixed on the left and right moving plate 2, providing guidance and support for the vertical movement of the up and down moving plate 1, ensuring the smoothness and accuracy of the movement. Simultaneously, the left and right moving plate 2 is designed with a dedicated pressure roller 7, whose function is to tension the synchronous belt 3, preventing slippage during transmission and ensuring transmission efficiency and precision. The left and right moving plate 2 is mounted on the left and right linear guide rail 14 via a connecting plate 10, enabling horizontal movement along the left and right linear guide rails, providing a foundation for the horizontal movement of the profile.

[0021] The linear guide includes a left-right linear guide 14 and a vertical linear guide 12. The left-right linear guide 14 is fixed on the frame of the material handling machine and provides guidance for the horizontal movement of the left and right moving plates 2, ensuring the linearity and stability of the horizontal movement of the left and right moving plates 2; the vertical linear guide 12 is fixed on the left and right moving plates 2 and provides guidance for the vertical movement of the up and down moving plates 1, ensuring the accuracy of the vertical movement of the up and down moving plates 1.

[0022] The synchronous belt 3 is a toothed synchronous belt. After passing through the pressure pulley 7, its left and right ends pass over the driving synchronous pulleys 8, which are respectively connected to the two servo motors, and its lower end passes over the driven synchronous pulley 9. The upper part is connected and fixed to the toothed plate of the upper and lower moving plate 1 through toothed engagement. The synchronous belt 3 is a crucial component for transmitting power to the servo motors. Its toothed structure ensures no relative slippage between it and the driving synchronous pulleys and the toothed plates of the upper and lower moving plate, achieving precise power transmission and thus guaranteeing the accuracy of the profile's movement.

[0023] Two servo motors 4 are provided, each connected to a drive synchronous pulley, providing power for the mechanism's movement. The servo motors 4 can precisely control speed and direction. Through different combinations of direction and speed, they drive the drive synchronous pulleys to rotate, which in turn drives the upper and lower moving plates and the left and right moving plates via a synchronous belt. For example, when the left motor is stationary and the right motor rotates clockwise, the right drive synchronous pulley 8 drives the synchronous belt 3. With the cooperation of the pressure pulley 7 and the driven synchronous pulley 9, the synchronous belt 3 drives the upper and lower moving plates 1 to move downwards along the vertical linear guide rail 12, thus causing the profile to move vertically downwards. The speed and position are precisely controlled by the right motor. When the right motor moves counterclockwise, the profile moves vertically upwards. The same vertical movement effect is produced when the left motor rotates and the right motor is stationary. When the left motor rotates clockwise and the right motor also rotates clockwise at the same speed, the two active synchronous pulleys drive the synchronous belt to make the left and right moving plates move to the right along the left and right linear guide rails, and the profile moves horizontally to the right accordingly; conversely, when the left motor rotates counterclockwise and the right motor also rotates counterclockwise at the same speed, the profile moves horizontally to the left.

[0024] Profile 5 is connected to the upper and lower moving plates 1 and serves as an intermediate component connecting the upper and lower moving plates and the pusher sheet metal, playing a supporting and motion-transmitting role. The movement of the upper and lower moving plates and the left and right moving plates is transmitted to the pusher sheet metal through the profile, driving the pusher sheet metal to perform various pushing actions.

[0025] The pusher sheet metal 6 is mounted on the profile 5 and comes into direct contact with the material to push it forward. Its shape and size can be designed according to the characteristics of the material to ensure the pushing effect.

[0026] The active synchronizing pulley 8 is connected to the output shaft of the servo motor, transmitting the rotational motion of the servo motor to the synchronous belt.

[0027] The driven synchronous pulley 9 serves to support the synchronous belt and change its direction of movement. It works in conjunction with the driving synchronous pulley and the pressure pulley to create a stable transmission path for the synchronous belt.

[0028] The connecting plate 10 is used to connect the left and right moving plates to the left and right linear guide rails to ensure that the left and right moving plates can move stably along the left and right linear guide rails.

[0029] By controlling the direction and speed of the two servo motors, the above actions can be combined into a square pushing trajectory required by the production process. First, control the two motors to rotate clockwise at the same speed, so that the profile moves horizontally to the right; then control the left motor to stay still and the right motor to rotate clockwise, so that the profile moves vertically downward; next, control the two motors to rotate counterclockwise at the same speed, so that the profile moves horizontally to the left; finally, control the left motor to stay still and the right motor to rotate counterclockwise, so that the profile moves vertically upward, completing a complete pushing cycle.

[0030] The feeding mechanism of the feeding machine in this embodiment achieves dual servo motor drive without pneumatic components through the synergistic effect of the above-mentioned components. It has the advantages of simple structure, high speed, precise control, convenient operation and flexible motion trajectory, which can effectively improve the working efficiency and feeding quality of the feeding machine.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
