Description

Technical Field

[0001] The utility model belongs to the technical field of powder material feeding equipment and relates to an automatic feeding device for rotational molding. Background Art

[0002] When the rotational molding machine discharges powder, it often needs to use a hopper. However, in the actual operation process, because the bottom of the hopper is often set in a conical shape and the top is set in a cylindrical shape, when the powder is accumulated in the hopper, it will cause the existence of force inside the powder. In particular, when the powder at the top of the hopper enters the bottom of the hopper, the squeezing force between the powders will be greater due to the smaller space. In this way, when the hopper is opened, only part of the powder is often discharged from the hopper, and the remaining part of the powder is still retained in the hopper. For this reason, people often need to stir it manually when discharging the hopper, which is inconvenient for people to operate. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a rotational molding automatic feeding device which can discharge powder smoothly.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 — Figure 4 As shown, the utility model provides an automatic feeding device for rotational molding, which includes a hopper 100 , a discharge pipe 110 , a blocking block 200 , a starting member 300 and an insert rod 210 .

[0020] A discharge pipe 110 is provided at the bottom end of the hopper 100, and a block 200 is provided in the hopper 100 to block the discharge pipe 110. The hopper 100 is also provided with a starter 300 to drive the block 200 to move. A plurality of plugging rods 210 are provided on one side of the block 200 facing the inside of the hopper 100. When people put powder into the hopper 100 and the robot transfers the hopper 100 to the rotational molding machine, the starter 300 drives the plugging ball to retract into the hopper 100, so that the discharge pipe 110 is connected to the inside of the hopper 100. In this way, the powder The material will fall from the hopper 100 into the rotational molding machine through the discharge pipe 110; further, because a plurality of insertion rods 210 are provided on the side of the blocking block 200 facing the inside of the hopper 100, and the plurality of insertion rods 210 are distributed in the shape of an umbrella skeleton when unfolded, therefore, when the starting member 300 drives the blocking ball to retract into the hopper 100, the insertion rod 210 will rise with the blocking ball, so that the insertion rod 210 moves in the powder pile of the hopper 100, thereby stirring the powder, so that the powder can smoothly fall from the hopper 100 to the discharge pipe 110.

[0021] The side of the block 200 facing the inside of the hopper 100 is configured to be conical. Through the configuration of this structure, the powder falling on this side of the block 200 can slide off the block 200 smoothly, avoiding the accumulation of powder on the block 200. The side of the block 200 facing the discharge pipe 110 is configured to be hemispherical, wherein the diameter of the hemispherical side of the block 200 is larger than the diameter of the discharge pipe 110, so that the block 200 can successfully block the discharge pipe 110.

[0022] The starting member 300 includes a cross frame 310 connected to the inner wall of the hopper 100, on which a starting cylinder 320 is arranged, on which a starting rod 330 is movably arranged, and the starting rod 330 movably passes through the cross frame 310 and is connected to the blocking block 200. When working, the starting cylinder 320 drives the starting rod 330 to rise and fall. Since the blocking block 200 is connected to the starting rod 330, both ends of the cross frame 310 are connected to the inner wall of the hopper 100, so as to realize the lifting and lowering of the blocking block 200 relative to the hopper 100, that is, to realize the opening or closing of the discharge pipe 110 by the blocking block 200.

[0023] A drop block 321 is provided at one end of the starting cylinder 320 away from the cross frame 310. When the powder drifts to the top of the starting cylinder 320, that is, the powder drifts onto the drop block 321, because the drop block 321 is hemispherical, the top surface of the starting cylinder 320 can be changed from a plane to a hemispherical surface, so that the powder drifting onto the drop block 321 can slide along the drop block 321 into the hopper 100.

[0024] A triangular plate 311 with a triangular cross section is provided on the top surface of the cross frame 310. By providing the triangular plate 311, the top surface of the truss can be changed from a flat surface to two inclined surfaces of the triangular plate 311, so that the powder falling onto the triangular plate 311 can slide along the inclined surfaces of the triangular plate 311 into the hopper 100.

[0025] The bottom end of the hopper 100 is configured to be conical, and through the configuration of this structure, the powder at the bottom of the hopper 100 can be smoothly gathered toward the discharge pipe 110 .

[0026] At least two supporting ears 120 are provided on the side of the hopper 100, and positioning holes 121 corresponding to the positioning columns are provided on the two supporting ears 120. When the hopper 100 is used to receive powder, people can place the hopper 100 on a shelf (not marked in the figure) suitable for the hopper 100. Specifically, the shelf is provided with positioning columns (not marked in the figure) that can pass through the positioning holes 121. When each positioning column is passed through the corresponding positioning hole 121, the supporting ears 120 are positioned and placed on the shelf, that is, the shelf and the hopper 100 are positioned and installed, and the shelf is fixedly installed on the ground. In this way, the hopper 100 can smoothly receive the powder.

[0027] An air hole 130 connected to the starting member 300 is provided on the side of the hopper 100, and a clamping block 140 is provided on the hopper 100 at the air hole 130. When the manipulator clamps the clamping block 140, the air circuit on the manipulator is connected to the air hole 130, that is, the air circuit on the manipulator is connected to the starting cylinder 320 of the starting member 300 through the air hole 130. In this way, the starting cylinder 320 can be controlled by the air circuit on the manipulator to drive the starting rod 330 to move.
