Description

Technical Field

[0001] This utility model relates to the field of baling machine technology, specifically to a stop mechanism for a strapping baling machine. Background Technology

[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] CN111319818A discloses a fully automatic Taobao box packing machine, belonging to the field of carton packing machine technology. It includes a frame, a conveying device, an alignment device, and two sets of double-link rope feeding and packing devices. A stack of Taobao boxes is conveyed from front to back by the conveying device. The A-size alignment mechanism of the alignment device clamps and aligns the stack of Taobao boxes by size A. The B-size paper-blocking mechanism of the alignment device blocks one side of the stack of Taobao boxes to align by size B. The pressing plate of the clamping mechanism of the alignment device presses the stack of Taobao boxes tightly. The rope feeding mechanism of the double-link rope feeding and packing devices uses a rope conveying arm to transport the binding rope above the stack of Taobao boxes to the knotter below for knotting and binding. This technology includes an alignment device between the conveying device and the packing device, where the alignment is performed after conveying. This adds an extra step to the processing, reducing efficiency. 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 stop mechanism for a strapping and packaging machine, addressing the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a baffle mechanism for a strapping and baling machine, comprising a frame, wherein the frame is provided with a conveying device for conveying materials, characterized in that: a fixed truss is located on one side of the frame of the conveying device, and a connecting shaft is provided between the fixed trusses for rotatably connecting several baffles, wherein the baffles abut against the materials, and a driving structure for driving the connecting shaft to rotate is provided on one or both sides of the fixed truss, wherein the driving structure can drive the baffles to rotate.

[0006] By adopting the above technical solution, several stops on the fixed truss are linked to the drive structure through connecting shafts. During the material conveying process, the stops directly abut against the side of the material and apply lateral alignment force, eliminating the need for an additional independent alignment process. After the conveying device finishes conveying, the drive structure drives the stops to rotate and lift to one side, and the material is then conveyed to the packaging mechanism for packaging via the conveyor belt, shortening the processing flow and improving the overall packaging efficiency.

[0007] The aforementioned baffle mechanism of a strapping and baling machine can be further configured such that: the driving structure includes telescopic cylinders on one or both sides of a fixed truss, a transmission rack is fixedly connected to the end of the telescopic cylinder, the connecting shaft passes through the fixed truss and is provided with a transmission gear at the end, and the transmission gear meshes with the transmission rack.

[0008] By adopting the above technical solution, the linear motion of the telescopic cylinder is converted into the rotational motion of the connecting shaft through the meshing of the transmission rack and transmission gear. The rotation of the connecting shaft can drive the stop lever to rotate to one side. At the same time, the overall structure has fewer parts and is easier to maintain. Compared with complex multi-link or cam mechanisms, it reduces the equipment failure rate and maintenance costs.

[0009] The aforementioned baffle mechanism of a strapping and baling machine can be further configured such that: the telescopic cylinder includes a cylinder body and a telescopic rod disposed within the cylinder body, and the transmission rack is fixedly connected to the end of the telescopic rod.

[0010] By adopting the above technical solution, the direct fixing of the telescopic rod and the rack makes the power transmission path shorter, the response speed faster, and avoids the reduction of processing efficiency due to transmission delay.

[0011] The aforementioned baffle mechanism of a strapping and baling machine can be further configured as follows: the connecting shaft sleeve is provided with at least two mounting parts for connecting the mounting rod, the mounting rod is rotatably disposed between the mounting parts, the mounting rod is sleeved with a plurality of fixing parts for fixing the baffle, and the baffle is vertically disposed with the fixing parts.

[0012] Using the above technical solution, at least two mounting parts on the connecting shaft provide support for the mounting rod, the mounting rod can rotate around its own axis, and the mounting rod is fitted with several fixing parts. The perpendicular arrangement of the stop bar and the fixing parts ensures lateral contact with the material.

[0013] The aforementioned baffle mechanism of a strapping and baling machine can be further configured such that: the fixing member includes a first clamping end connected to the mounting rod and a second clamping end connected to the baffle, the baffle is vertically installed on the second clamping end, and both the first clamping end and the second clamping end are provided with locking holes for locking the clamping end.

[0014] Using the above technical solution, the first clamping end forms a ring-shaped fixation with the mounting rod through the clamping structure, and the fastener in the locking hole realizes the locking and adjustment of the installation position, which facilitates the flexible adjustment of the stop bar spacing along the axial direction of the mounting rod to adapt to the alignment requirements of materials of different widths; the second clamping end and the vertical clamping design of the stop bar are combined with the fastening of the locking hole for installation.

[0015] The aforementioned baffle mechanism of a strapping and baling machine can be further configured such that the fixed truss is connected to the frame via an adjustment structure, the adjustment structure enabling the fixed truss to be axially adjusted between the conveying device and the baling structure.

[0016] By adopting the above technical solution, the axial position adjustment of the stop mechanism between the conveying device is realized through the adjustable connection between the fixed truss and the frame, enabling the stop mechanism to adapt to materials of different sizes.

[0017] The aforementioned baffle mechanism of a strapping and baling machine can be further configured as follows: the adjustment structure includes mounting plates on both sides of the frame, a rod seat on the top of the mounting plate, a movable rod between the rod seats, the movable rod being arranged along the extension direction of the frame, a slider being slidably mounted on the movable rod, and a fixed truss being fixedly installed on the top of the slider.

[0018] Using the above technical solution, the moving rod is arranged along the extension direction of the frame, and the slider can slide along its axial direction and drive the fixed truss to move synchronously, so as to meet the alignment requirements under different material specifications.

[0019] The beneficial effects of this utility model are as follows: Several stops on the fixed truss are linked to the drive structure through the connecting shaft. During the material conveying process of the conveying device, the stops directly abut against the side of the material and apply lateral alignment force, which shortens the processing flow and improves the overall packaging efficiency.

The telescopic cylinder 6 includes a cylinder body 9 and a telescopic rod 10 set in the cylinder body 9. The transmission rack 7 is fixedly connected to the end of the telescopic rod 10. The direct fixation of the telescopic rod 10 and the rack makes the power transmission path shorter and the response speed faster, avoiding the reduction of processing efficiency due to transmission delay.
