[0002] A strapping and packing machine is a packaging device used to automatically strap and secure items. It mainly uses strapping tape to wrap, tighten, weld, or snap together items such as cartons, pallets, and packages to form a sturdy packaging unit. It can be fully automatic, semi-automatic, or manual, depending on the needs, and is suitable for packaging scenarios of items of different sizes and weights.

[0003] CN118811169A discloses an integrated feeding, lifting, strapping, and forming machine, relating to the technical field of integrated feeding, lifting, strapping, and forming machines. It includes a feeding rack mechanism, a strapping machine mechanism, a feeding rack mechanism, a pressing mechanism, and a pushing rack mechanism. This integrated feeding, lifting, strapping, and forming machine achieves efficient automated operation by integrating these mechanisms. The feeding rack mechanism effectively controls the transmission and positioning of the material belt; the strapping machine mechanism ensures the stability and accuracy of the strapping process; the feeding rack mechanism provides reliable feeding capability; the pressing mechanism enhances the uniformity and stability of the pressing; and the pushing rack mechanism further improves the material pushing efficiency. However, the pushing rack mechanism in this technology lacks a material fixing mechanism. During the pushing process, if the material is too light or too small, it may fall, affecting subsequent work. Therefore, this technology still has room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a push plate mechanism for a strapping and packaging machine, which addresses the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pusher plate mechanism for a strapping and baling machine, comprising a frame, wherein the frame is provided with a feeding mechanism for conveying materials and a pusher plate mechanism for pushing materials, characterized in that: the pusher plate mechanism includes a pusher plate disposed on one side of the feeding mechanism, the frame is provided with a driving structure for driving the pusher plate to reciprocate along the extension direction of the frame, the pusher plate is provided with a plurality of mounting cavities, and the mounting cavities are provided with a pressing and fixing structure for pressing and fixing the materials after feeding.

[0006] By adopting the above technical solution, after the feeding mechanism completes the material conveying, the pressing structure can apply downward pressure to the material before and during the pushing process, which effectively solves the problem of the material falling during pushing due to its lightness or small size in the prior art, and ensures that the material remains stable in the pushing path.

[0007] The push plate mechanism of the above-mentioned strapping and baling machine can be further configured as follows: the pressing structure includes a base plate disposed on one side of the mounting cavity, a telescopic cylinder is fixedly installed on the top of the base plate, a pressing block is hinged to the end of the telescopic cylinder, and a support member is also provided on the top of the telescopic cylinder as a support for the pressing block. The support member is hinged to the pressing block, the pressing block passes through the mounting cavity, and when the telescopic cylinder extends, it causes the pressing block to abut against the material.

[0008] Using the above technical solution, the telescopic cylinder is fixedly installed on the upper part of the base plate, and its end is hinged to the pressure block. The support is also hinged to the pressure block. During the process of the telescopic cylinder extending to make the pressure block come into contact with the material, the support can effectively support and guide the pressure block, preventing the pressure block from shifting or deforming under pressure. When the telescopic cylinder extends, it lifts the end of the pressure block and presses the material down with the hinge point of the support as the center, thus fixing the material.

[0009] The push plate mechanism of the above-mentioned strapping and baling machine can be further configured as follows: the telescopic cylinder includes a cylinder body and a telescopic rod, the telescopic rod is hinged to the pressure block, and the support member includes an installation member fixedly connected to the cylinder body and a hinge block with one end hinged to the installation member and the other end hinged to the pressure block.

[0010] Using the above technical solution, the telescopic cylinder drives the pressure block to press down through the cylinder body and telescopic rod. The mounting part is fixedly connected to the cylinder body to ensure stable support. The two ends of the hinge block are respectively hinged to the mounting part and the pressure block, so that the pressure block is pressed down with the hinge part as the center under the drive of the telescopic rod.

[0011] The push plate mechanism of the above-mentioned strapping and packaging machine can be further configured as follows: the machine frame has mounting plates on both sides for connecting to slide rails, the slide rails are slidably provided with sliders, the top of the sliders is provided with mounting blocks, and a push plate truss for fixed connection of the push plate is provided between the mounting blocks.

[0012] Using the above technical solution, the mounting plates on both sides of the frame are equipped with slide rails, and the sliding cooperation between the slide rails and the slider enables the push plate to be moved and set on the frame. The push plate truss is set between the mounting blocks on the top of the slider, distributing the load of the push plate to the slide rails on both sides to form a balanced force structure.

[0013] The push plate mechanism of the above-mentioned strapping and packaging machine can be further configured as follows: the drive component includes a first synchronous wheel disposed at both ends of the slide rail, a drive motor is provided on one side of the frame, the drive motor passes through the frame and a second synchronous wheel is provided, a third synchronous wheel is provided on one side of the first synchronous wheel, the first synchronous wheel and the second synchronous wheel and the third synchronous wheel are connected by a synchronous belt, and the synchronous belt between the first synchronous wheels is placed between the mounting block and the slider and clamped and fixed between the mounting block and the slider.

[0014] Using the above technical solution, the first synchronous pulleys at both ends of the slide rail are connected by a synchronous belt. The synchronous belt is clamped and fixed between the mounting block and the slider, so that the linear motion of the synchronous belt can be directly converted into the reciprocating motion of the push plate truss. The drive motor is connected to the second and third synchronous pulleys by the synchronous belt. At the same time, the third synchronous pulley is connected to the first synchronous pulley, which enables the drive motor to drive the first synchronous pulley to rotate. The rotation of the first synchronous pulley can drive the back axis to reciprocate.

[0015] The push plate mechanism of the above-mentioned strapping and packaging machine can be further configured as follows: the frame is provided with a fixed frame on one side of the first synchronous wheel, the fixed frame is axially provided with a rotating shaft, and the first synchronous wheel and the third synchronous wheel are sleeved on the rotating shaft.

[0016] By adopting the above technical solution, the fixed frame on the machine provides support for the rotating shaft, while ensuring the coaxiality of the first synchronous pulley and the third synchronous pulley.

[0017] The push plate mechanism of the above-mentioned strapping and packaging machine can be further configured as follows: the push plate includes a fixed end fixedly connected to the push plate truss and a pushing end disposed on one side of the fixed end. The fixed end is horizontally disposed with the push plate truss, and the pushing end is vertically disposed with the fixed end to make the push plate L-shaped.

[0018] Using the above technical solution, the fixed end is horizontally fixed to the push plate truss to ensure the connection between the push plate and the truss. The push end extends vertically downward to form an L-shaped bend, so that the push end can contact and push the material.

[0019] The beneficial effects of this utility model are as follows: a pressure-fixing structure is set in the push plate. When the telescopic cylinder extends, the telescopic cylinder lifts the end of the pressure block and presses the material down with the hinge point of the support member as the center, thereby fixing the material.
