Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, and in particular relates to a material pulling device. Background Technology

[0002] Currently, when sawing materials (such as pipes), a clamping device is needed to hold and transfer the materials for processing. The length of the transferred materials is often subject to strict requirements. When the transfer length is large, the materials need to be clamped and transferred multiple times, resulting in poor work continuity and low material transfer efficiency. At the same time, during the repeated transfer process, the moving materials will rub against the support rollers and limiting side plates supporting the materials, causing scratches or wear on the material surface. Utility Model Content

[0003] This utility model provides a material pulling device to meet the needs of different conveying distances, thereby improving work efficiency and solving the problem of materials being scratched or worn.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a material pulling device, including a frame, a power seat driven by a driving device is slidably mounted on the frame, a mounting seat is provided on the power seat, and a limiting sliding mechanism is provided between the mounting seat and the frame;

[0005] A lifting seat is arranged on one side of the mounting base, and multiple swing lifting arms are hinged between the lifting seat and the mounting base. A lifting power mechanism is provided between the lifting seat and the power seat.

[0006] The lifting seat is provided with a clamping seat, the clamping seat is provided with a stop block, and the clamping seat on the side opposite to the stop block is provided with a clamping block driven by a first linear drive element.

[0007] As an improvement, the limiting sliding mechanism includes a support wheel platform fixedly installed on the frame and a wheel seat disposed on the mounting base. The wheel seat is provided with a plurality of rollers, which are distributed on the top and bottom surfaces of the support wheel platform and abut against it.

[0008] Multiple limiting wheels are rotatably mounted on the wheel base. The axial center line of the limiting wheel is perpendicular to the axial center line of the roller. The limiting wheel abuts against the side of the support wheel platform away from the mounting base.

[0009] As an improvement, the lifting power mechanism includes a second linear drive element disposed on the power base and a hinge block disposed on the lifting base, wherein a connecting rod is hinged between the second linear drive element and the hinge block.

[0010] As an improvement, the lifting seat and the mounting seat are provided with hinge seats on the same side, and the lifting seats corresponding to the positions of all the swing lifting arms are provided with clearance holes. All the swing lifting arms pass through the clearance holes and are respectively hinged to a hinge seat at both ends.

[0011] As a further improvement, both the stop block and the clamping block are equipped with lining plates on their working sides.

[0012] As a further improvement, the clamping block is provided with a guide rod that is slidably mounted on the clamping seat.

[0013] As a further improvement, the drive device includes a rack mounted on the frame, and the power base is provided with a drive gear driven by a power source and cooperating with the rack.

[0014] After adopting the above technical solution, the effect of this utility model is:

[0015] The material pulling device includes a frame, on which a power seat driven by a drive device is slidably mounted. A mounting seat is provided on the power seat, and a limiting sliding mechanism is provided between the mounting seat and the frame. A lifting seat is arranged on one side of the mounting seat, and multiple swing lifting arms are hinged between the lifting seat and the mounting seat. A lifting power mechanism is provided between the lifting seat and the power seat. A clamping seat is provided on the lifting seat, and a stop is provided on the clamping seat. A clamping block driven by a first linear drive element is provided on the clamping seat opposite the stop. Based on the above structure, the material pulling device is connected downstream of the upstream feeding equipment during operation. When transferring materials, the drive device moves the power seat to a suitable position, and the upstream feeding equipment conveys the material between the stop and the clamping block. Then, the first linear drive element drives the clamping block to move and cooperates with the stop to clamp the material. Then, through the drive of the lifting power mechanism and the swinging cooperation of the swing lifting arms, the clamped material rises and disengages from the conveying component on the upstream feeding equipment. Finally, through the drive of the drive device and its cooperation with the limiting sliding mechanism, the material is transferred.

[0016] In summary, this material pulling device can meet the needs of transferring materials of different specifications and distances without interruption, effectively ensuring work efficiency. At the same time, during the transfer process, the materials are lifted and transferred without contacting the conveying components, effectively solving the problem of materials being scratched or worn.

[0017] The limiting sliding mechanism includes a support wheel platform fixedly mounted on the frame and a wheel seat mounted on the mounting base. The wheel seat has multiple rollers distributed on the top and bottom surfaces of the support wheel platform and abutting against it. Multiple limiting wheels are also rotatably mounted on the wheel seat. The axial center lines of the limiting wheels are perpendicular to the axial center lines of the rollers. The limiting wheels abut against the side of the support wheel platform away from the mounting base. Thus, during material movement, the cooperation between the rollers and the support wheel platform provides support and guidance for the mounting base. The cooperation between the limiting wheels and the support wheel platform ensures the linearity and smoothness of the mounting base's movement, while also preventing the rollers from detaching from the support wheel platform during operation.

[0018] The lifting power mechanism includes a second linear drive element mounted on the power base and a hinge block mounted on the lifting base. A connecting rod is hinged between the second linear drive element and the hinge block. When lifting or returning materials, the second linear drive element drives the connecting rod to work. The driving force of the connecting rod acts on the lifting base, and the lifting or returning action of the lifting base is completed by the swing of the swing lifting arm. The structure is simple, the action steps are few, and the response speed is fast.

[0019] Since the lifting seat and the mounting seat are both equipped with hinge seats on the same side, and the lifting seats corresponding to all the swing lifting arms are equipped with clearance holes, all the swing lifting arms pass through the clearance holes and are hinged to a hinge seat at both ends. Thus, through the above structure, not only is the normal swing lifting of the lifting seat guaranteed, but the structure is also highly compact and has a low space occupancy rate.

[0020] Since both the stop block and the clamping block have liner plates installed on their working sides, the liner plates come into direct contact with the material when clamping and moving it, thus protecting the stop block and the clamping block.

[0021] Because the clamping block is equipped with a guide rod that is slidably mounted on the clamping seat, when the first linear drive element drives the clamping block to move, the guide rod slides synchronously on the clamping seat, which plays a guiding role in the movement, ensuring the linearity of the movement of the clamping block and the reliable fit with the pipe, thereby effectively ensuring the reliability of the pipe being clamped.

[0022] Since the drive unit includes a rack mounted on the frame, and the power base is equipped with a drive gear that is driven by a power source and cooperates with the rack, the reliability and stability of the drive during the material movement process are ensured through the cooperation of the rack and the drive gear.
