Description

Technical Field

[0001] This utility model relates to the technical field of water-based resin production equipment, and in particular to a material unloading cart. Background Technology

[0002] In the production of water-based resins, a pouring cart is generally used to pour the resin material into the reactor during the slurry preparation process. Currently available pouring carts are equipped with a can-holding mechanism that clamps the resin tank. This mechanism uses a tensioning device to lock and hold the resin tank securely. The current tensioning device on unloading trolleys is generally similar to the clamping and locking mechanism in Chinese Patent Application No. 2022213729607, entitled "A Tiltable Oil Drum Lifting Tool," which includes an adjusting seat and a limiting seat connected by a chain. The limiting seat has several opening slots; the front end of the chain has several limiting posts that engage with the opening slots; the adjusting seat has a vertically moving positioning handle and a horizontally rotating locking handle. The bottom of the locking handle is fixedly connected to a sprocket that cooperates with the chain, and the bottom of the positioning handle has an insert block. When the locking handle is rotated horizontally, the sprocket contacts the chain and gradually tightens. Then, the sprocket is fixed by the insert block at the bottom of the positioning handle. The positioning handle can change the angle of the insert block by rotating its upper handle, thus achieving the extension and retraction of the insert block. This structure requires sequential operation of the locking handle and the positioning handle to achieve locking, which is relatively complex, has high production costs, is cumbersome to operate, and is not convenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide a material unloading cart, which has the advantages of simple structure, reasonable design, low production cost, convenient operation and use.

[0004] The technical solution of this utility model is implemented as follows: a material handling cart includes a seat; a lifting frame is installed on the seat, and a can-holding mechanism is installed on the lifting frame; the can-holding mechanism includes a back plate and two clamping plates; the left and right ends of the back plate are rotatably mounted on the lifting frame, and the rotation axis of the back plate relative to the lifting frame is parallel to the horizontal plane; a clamping plate is rotatably mounted on each of the left and right sides of the back plate, and the rotation axis of each clamping plate relative to the back plate is perpendicular to the rotation axis of the back plate relative to the lifting frame; a tilting drive device for driving the back plate to rotate is also installed on the lifting frame; in particular, the can-holding mechanism also includes a tensioning device; the tensioning device includes a clamping seat, a mounting seat, a sliding member, a tensioning member, and a cable; wherein: The mounting base is installed on one of the clamps, and the mounting base is provided with a mounting recess; The mounting base is mounted on another clamping plate, and the mounting base is provided with a sliding hole and a rotating hole; the axis of the sliding hole is perpendicular to the axis of rotation of the clamping plate relative to the back plate; the rotating hole is located on the side of the sliding hole facing away from the mounting base, and the axis of the rotating hole is collinear with the axis of the sliding hole. The slider is inserted into the sliding hole, and a linear guide structure is provided between the slider and the sliding hole, so that the slider can move linearly along the axis of the sliding hole without relative rotation.

Finally, the lifting frame raises the resin tank, allowing the tilting drive to rotate and pour the resin onto the reactor. This structure is simple, has low production costs, and is very easy to operate; simply rotating the tensioning component is sufficient to grip the resin tank.

The mounting base 35 is provided with a sliding hole 351 and a rotating hole 352. The axis of the sliding hole 351 is perpendicular to the axis of rotation of the clamping plate 32 relative to the back plate 31. The rotating hole 352 is located on the side of the sliding hole 351 that is away from the mounting base 34, and the axis of the rotating hole 352 is collinear with the axis of the sliding hole 351. The slider 36 is inserted into the sliding hole 351. A linear guide structure 6 is provided between the slider 36 and the sliding hole 351.
