It is mainly used in logistics, manufacturing, warehousing and other fields.

[0003] According to publication number CN215514281U, the title is "A Track for the Circulation of Bundled Materials with Bundling Straps," which solves the problem of complex assembly processes for flip-type metal blade structures in related technologies. However, the aforementioned patent lacks a displacement function with locking positioning, and the guide stroke of the bundling wire cannot be adjusted, causing the bundling wire to become entangled and knotted during transmission, hindering wire feeding and reducing the bundling efficiency of roll products. Utility Model Content

[0004] The purpose of this utility model is to provide a locking and positioning structure for a strapping machine track trolley, in order to solve the technical problems mentioned in the background art, such as the lack of displacement function with locking and positioning, and the inability to adjust the guide stroke of the strapping wire, which causes the strapping wire to become entangled and knotted during transmission, thus preventing better wire feeding.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: a locking and positioning structure for a strapping machine track plate car, including a shuttle car ground rail, a shuttle car plate frame is rotatably connected to the shuttle car ground rail, a strapping wire guide frame is fixed on the shuttle car plate frame, and a strapping machine for strapping the product with strapping wire is provided on one side of the strapping wire guide frame. The bottom of the shuttle car frame is equipped with a displacement component that matches the locking and positioning of the shuttle car ground rail, and a servo motor with a reducer is fixed on one side of the bottom of the shuttle car frame, and a drive shaft is fixed on the outside of the reducer through a coupling. The binding wire guide frame is provided with a guide assembly for guiding the binding wire to the binding machine, and the guide assembly includes a transfer guide wheel, an auxiliary guide wheel and a reversing guide wheel that rotate on the binding wire guide frame.

[0008] Preferably, both the drive shaft and the driven shaft are rotatably coupled to the shuttle car frame via bearings, and both the drive sprocket and the driven sprocket, as well as the chains on them, adopt a double-row design.

[0009] Preferably, optical grating sensors are fixed on both sides of the shuttle car frame, and anti-detachment rollers that roll in conjunction with the shuttle car ground rail are provided at the four corners of the shuttle car frame via support plates.

[0015] The locking and positioning structure of the strapping machine track trolley of this utility model has the following advantages: This type of strapping machine track trolley locking and positioning structure uses a reducer on a servo motor to drive two sets of drive sprockets and drive wheels on the drive shaft, while also quickly decelerating and locking, offering high flexibility. Two chains then drive two sets of driven sprockets and driven wheels synchronously, thereby controlling the shuttle trolley frame and its entirety to move smoothly and lock and position as needed on the shuttle trolley ground rail. During the guidance of the strapping wire, the electric push rod is first opened, and the connecting seat drives the horizontal slide frame to adapt to the horizontal displacement on the horizontal slide arm, which in turn drives the strapping wire guide wheel to adjust outward or inward, changing the guide stroke of the strapping wire. Then, the intermediate guide wheel, auxiliary guide wheel, and reversing guide wheel better guide the strapping wire onto the strapping machine, enabling efficient strapping of the roll products on the rotary table.

[0024] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed description of a locking and positioning structure for a strapping machine track trolley.

[0025] like Figures 1-9As shown, the present invention discloses a locking and positioning structure for a strapping machine track trolley, including a shuttle car ground rail 1, a shuttle car frame 2 rotatably connected to the shuttle car ground rail 1, and a strapping wire guide frame 3 fixed on the shuttle car frame 2. A strapping machine 4 for strapping products is provided on one side of the strapping wire guide frame 3. A strapping wire roll frame 12 for placing strapping wire rolls is fixed on the other side of the shuttle car frame 2 to facilitate the placement of strapping wire rolls. A rotating table 13 for strapping with the strapping machine 4 is placed on the outside of the shuttle car ground rail 1. The rotating table 13 is linearly rotated by its own drive motor through gears. The roll product to be strapped is placed on it. The rotating table 13 drives the roll product on it to rotate linearly, and the strapping wire on the strapping machine 4 performs a uniform strapping operation on the linearly rotating roll product. The bottom of the shuttle frame 2 is equipped with a displacement component that matches the locking and positioning of the shuttle ground rail 1. A servo motor 51 with a reducer 52 is fixed on one side of the bottom of the shuttle frame 2, and an active shaft 53 is fixed on the outside of the reducer 52 through a coupling, so as to perform smooth displacement and locking positioning as needed. The binding wire guide frame 3 is equipped with a guide component for guiding the binding wire to the binding machine 4. The guide component includes a central guide wheel 66, an auxiliary guide wheel 67 and a reversing guide wheel 68 that rotate on the binding wire guide frame 3, so as to change the guiding stroke of the binding wire and better guide the binding wire to the binding machine 4, so as to perform efficient binding operation on the roll products on the rotary table 13.

[0026] The displacement assembly also includes drive sprockets 54 and drive wheels 55 fixed at both ends of the drive shaft 53. The two sets of drive sprockets 54 and drive wheels 55 on the drive shaft 53 are driven by the reducer 52 on the servo motor 51, and can also be quickly decelerated and locked, which is highly flexible. A chain 56 is engaged on the outside of the drive sprocket 54, and a driven sprocket 58 is engaged on the outside of the chain 56. A driven shaft 57 is sleeved inside the driven sprocket 58, and driven wheels 59 are fixed at both ends of the driven shaft 57. The two chains 56 drive the two sets of driven sprockets 58 and driven wheels 59 to transmit synchronously, thereby controlling the shuttle car frame 2 and its whole body to move smoothly and lock and position on the shuttle car ground rail 1 as needed. Both the drive shaft 53 and the driven shaft 57 are rotatably coupled to the shuttle frame 2 via bearings, improving the rotational stability of the drive shaft 53 and the driven shaft 57. Furthermore, the drive sprocket 54 and the driven sprocket 58, along with their chains 56, adopt a double-row design, enhancing the tightness of the engagement between the drive sprocket 54 and the driven sprocket 58 and the chains 56, improving the power transmission of the chains 56, and facilitating the smooth displacement of the shuttle frame 2 on the shuttle ground rail 1. Optical grating sensors 7 are fixed on both sides of the shuttle frame 2 to monitor the displacement stroke of the shuttle frame 2. The system monitors the movement of the shuttle car frame 2 in real time. Each of the four corners of the shuttle car frame 2 is equipped with anti-derailment rollers 8 that roll in conjunction with the shuttle car ground rail 1 via support plates. These rollers prevent the shuttle car frame 2 from detaching from the ground rail 1 and also prevent the shuttle car frame 2 from shaking during its movement. Signal sensors 9, which are used in conjunction with the shuttle car frame 2, are fixed on both sides of the shuttle car ground rail 1. These sensors detect the beginning and end of the movement of the shuttle car frame 2 using optical signals, further improving the accuracy of the shuttle car frame 2's movement and preventing the shuttle car frame 2 from derailing from the shuttle car ground rail 1.

[0027] The guiding assembly also includes a horizontal sliding arm 61 fixed to the top of the binding wire guide frame 3, and an electric push rod 62 is horizontally placed on the outer side of the horizontal sliding arm 61. A connecting seat 63 is fixed on the piston rod of the electric push rod 62, and a horizontal sliding frame 64 that slides with the horizontal sliding arm 61 is fixed on the inner side of the connecting seat 63. The electric push rod 62 is controlled to open and drive the horizontal sliding frame 64 to adapt to the horizontal displacement on the horizontal sliding arm 61 through the connecting seat 63, and to rotate the binding wire guide wheel 65 on the outer side of the horizontal sliding frame 64. The horizontal sliding frame 64 drives the binding wire guide wheel 65 to adjust outward or inward, changing the guiding stroke of the binding wire. Then, the intermediate guide wheel 66, the auxiliary guide wheel 67 and the reversing guide wheel 68 guide the binding wire to the binding machine 4 for efficient binding of the roll products on the rotary table 13. A displacement sensor 10 is fixed to the outer side of the horizontal slide 64 near the binding wire guide wheel 65 to monitor the displacement of the horizontal adjustment stroke of the horizontal slide 64 and ensure that the horizontal stroke of the binding wire guide wheel 65 is adjusted in place. A guide cover 11 for guiding the binding wire is fixed to the bottom of the horizontal slide 64 near the binding wire guide wheel 65 to pre-guide the binding wire and prevent it from becoming tangled. Small limit wheels roll on the outer side of the transfer guide wheel 66, the auxiliary guide wheel 67, the reversing guide wheel 68 and the binding wire guide wheel 65, which play a role in preventing the binding wire from falling off and limiting its transmission as it passes through the transfer guide wheel 66, the auxiliary guide wheel 67, the reversing guide wheel 68 and the binding wire guide wheel 65, thereby improving the orderly transmission of the binding wire.

[0028] The working principle of a strapping machine track trolley locking and positioning structure is as follows: First, the servo motor 51 is turned on and drives the drive sprockets 54 and drive wheels 55 at both ends of the drive shaft 53 to rotate synchronously through the reducer 52. The two sets of drive sprockets 54 drive the driven sprockets 58 and driven wheels 59 at both ends of the driven shaft 57 to rotate synchronously through two rows of chains 56. With the anti-detachment rollers 8 providing anti-detachment rolling cooperation to the shuttle trolley frame 2 and the shuttle trolley ground rail 1, the two sets of drive wheels 55 and driven wheels 59 then drive the shuttle trolley frame 2 to move smoothly on the shuttle trolley ground rail 1. During this process, the optical grating transmits the signal. Sensor 7 and signal sensor 9 monitor the displacement of the shuttle car frame 2 on the shuttle car ground rail 1 in real time. The shuttle car frame 2 moves the binding wire guide frame 3, binding machine 4 and binding wire roll frame 12 to the roll product on one of the rotating tables 13. Servo motor 51 is turned off, and reducer 52 immediately intervenes and controls the drive sprocket 54 and drive wheel 55 at both ends of drive shaft 53 to lock. The driven sprocket 58 and driven wheel 59 at both ends of driven shaft 57 lose driving force. Then the shuttle car frame 2 is locked and stationary on the shuttle car ground rail 1. Simultaneously, the electric push rod 62 is opened as needed, and the connecting seat 63 drives the horizontal slide frame 64 to move horizontally outward or inward on the horizontal slide arm 61. The horizontal slide frame 64 drives the binding wire guide wheel 65 to adjust horizontally outward or inward accordingly. The displacement sensor 10 monitors the horizontal adjustment stroke of the binding wire guide wheel 65 in real time. After the binding wire guide wheel 65 has adjusted the guiding stroke of the binding wire to the correct position, under the pulling action of the binding machine 4, the binding wire at the binding wire roll 12 is forced to pass through the binding wire guide wheel 65 sequentially from the guide cover 11. The intermediate guide wheel 66 and the auxiliary guide wheel 67 are then guided by the reversing guide wheel 68 to the binding arm of the binding machine 4, and the roll products on the first set of rotating tables 13 are rotated and bound. In this way, the shuttle car plate frame 2 is first controlled to unlock on the shuttle car ground rail 1, and continues to move, and drives the binding wire guide frame 3, the binding machine 4 and the binding wire roll frame 12 to move to the roll products on the second set of rotating tables 13. Then the binding machine 4 rotates and binds the roll products that have arrived on the second set of rotating tables 13 in the same way.

[0029] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
