[0046] Referring to Figures 1 to 3The embodiment provides a sheet metal part feeding device, which comprises a rotating shaft 10, a support plate 30 and a driving mechanism 40.

[0047] The rotating shaft 10 is arranged at the feeding end of the mesh belt conveyor and is located above the conveying belt 20 of the mesh belt conveyor. The support plates 30 are arranged along the outer periphery of the rotating shaft 10, are connected with the outer wall of the rotating shaft 10 and extend along the radial direction of the rotating shaft 10. The driving mechanism 40 is used for driving the rotating shaft 10 to rotate. Two adjacent support plates 30 form a containing groove 31 for containing sheet metal parts. The containing groove 31 is used for receiving the sheet metal parts falling from above. The axial direction of the rotating shaft 10 is perpendicular to the conveying direction of the conveying belt 20 of the mesh belt conveyor.

[0048] In the embodiment, the conveying belt 21 above intermittently conveys the sheet metal parts to the support plates 30 above and then the sheet metal parts fall into the containing grooves 31. When a large number of sheet metal parts fall into the containing grooves 31 and are stacked, the sheet metal parts are dispersed along the axial direction of the rotating shaft 10. The rotating shaft 10 drives the support plates 30 to rotate. When the support plates 30 forming the containing grooves 31 are inclined, the sheet metal parts slide along the support plates 30 to the conveying belt 20 of the mesh belt conveyor below.

[0049] Through the rotation of the rotating shaft 10, the containing grooves 31 successively receive the sheet metal parts and convey the sheet metal parts in the containing grooves 31 to the conveying belt 20 below in sequence. When the sheet metal parts fall into the containing grooves 31, the sheet metal parts hit the rotating shaft 10 and are scattered along the axial direction of the rotating shaft 10, so that the sheet metal parts are distributed in a wider range along the axial direction of the rotating shaft 10 (that is, the sheet metal parts can be distributed in a larger range along the width of the conveying belt 20 in the subsequent process). When the sheet metal parts slide out of the containing grooves 31 to the conveying belt 20 below, the sheet metal parts first contacting the conveying belt 20 are conveyed away by the conveying belt 20 first, which makes the sheet metal parts sliding out of each containing groove 31 be distributed more uniformly along the conveying direction of the conveying belt 20, thereby reducing the degree of stacking of the sheet metal parts on the conveying belt 20, and further shortening the time required for drying the sheet metal parts after cleaning and improving the drying effect.

[0050] In one embodiment, the instantaneous moving direction of the rotating shaft 10 near one end of the conveying belt 20 of the mesh belt conveyor is opposite to the conveying direction of the conveying belt 20 of the mesh belt conveyor.

[0051] In the embodiment, as shown in the figure, the conveying belt 20 of the mesh belt conveyor moves to the right, and the rotating shaft 10 rotates clockwise. The rotating shaft 10 drives the support plates 30 to rotate, and the subsequent sheet metal parts slide down along the support plates 30 to the conveying belt 20. The moving direction of the sheet metal parts is the same as the conveying direction of the conveying belt 20, so that the sheet metal parts are not stacked on the conveying belt 20 (if the moving direction of the sheet metal parts is opposite to the conveying direction of the conveying belt 20, the sheet metal parts are prone to be stagnant on the conveying belt 20 for a period of time, and the subsequent sheet metal parts are prone to be stacked on the front sheet metal parts).

[0052] In one embodiment, the support plate 30 is provided with a plurality of through holes 32. The support plate 30 has a receiving surface 33 for receiving the sheet metal parts. The sheet metal part feeding device further comprises a plurality of friction blocks 50 and a pushing assembly 60.

[0053] Each friction block 50 is slidingly arranged in a corresponding through hole 32, and the friction block 50 can protrude from the receiving surface 33. The pushing assembly 60 is used to push the friction blocks 50. The friction blocks 50 are used to rub against the sheet metal parts to block the sheet metal parts, i.e., to hinder the movement of the sheet metal parts by using friction and to make the sheet metal parts stay. The friction blocks 50 can be made of rubber.

[0054] In this embodiment, the friction between the support plate 30 and the sheet metal parts is small, such as Figure 1 and Figure 3 The conveying belt 21 is located above and to the right of the device, the rotating shaft 10 rotates clockwise, the sheet metal parts conveyed by the conveying belt 21 move in a left parabolic trajectory to the receiving surface 33 of the support plate 30, and the sheet metal parts slide along the receiving surface 33 to the bottom of the accommodating groove 31. During this process, the pushing assembly 60 drives the friction blocks 50 to protrude from the receiving surface 33. The sheet metal parts in contact with the friction blocks 50 are blocked by a large friction force, and the other sheet metal parts stacked on the sheet metal parts are easily separated from each other on one hand due to the impact and vibration of the receiving surface 33 of the support plate 30, and on the other hand the lower sheet metal parts are blocked and slide relative to the upper sheet metal parts, so that the stacked sheet metal parts are separated on the support plate 30, and then a large number of sheet metal parts are distributed along the radial direction of the rotating shaft 10. Then the rotating shaft 10 rotates, the receiving surface 33 is inclined, the friction blocks 50 retract into the through holes 32, and the sheet metal parts sequentially slide down the receiving surface 33 to the lower conveying belt 20, which makes the sheet metal parts sequentially distributed along the conveying direction of the conveying belt 20 on the conveying belt 20, further improving the drying efficiency.

[0055] In one embodiment, the pushing assembly 60 comprises a plurality of connecting rods 61, a limiting block 62, and a pushing plate 63.

[0056] The connecting rods 61 are provided in plurality, and each of the plurality of connecting rods 61 is connected to a side of the support plate 30 away from the receiving surface 33. The limiting block 62 is connected to an end of the connecting rod 61 away from the support plate 30. The pushing plate 63 is slidingly connected to the plurality of connecting rods 61 through the openings, the pushing plate 63 is connected to the plurality of friction blocks 50, and the pushing plate 63 can abut against the limiting block 62. The distance between the limiting block 62 and the rotating shaft 10 is greater than the distance between the connecting rod 61 and the rotating shaft 10. The axis of the connecting rod 61 is perpendicular to the axis of the rotating shaft 10; the angle between the connecting rod 61 and the end surface of the support plate 30 is less than 45 degrees. The angle between the connecting rod 61 and the end surface of the support plate 30 can be selected in the range of 25-40 degrees.

[0057] In this embodiment, asFigure 3 When the rotating shaft 10 rotates clockwise, when the support plate 30 is above the rotating shaft 10, under the action of gravity, the push plate 63 slides close to the support plate 30 and finally abuts against the support plate 30, at this time the friction block 50 connected with the push plate 63 protrudes from the accommodation hole 32. The support plate 30 rotates to the upper right of the rotating shaft 10, at this time the upper right conveying belt 21 intermittently outputs the sheet metal parts above the support plate 30, the sheet metal parts contact the upper end surface (the receiving surface 33) of the support plate 30 at this time, part of the sheet metal parts are blocked by the friction block 50, and part of the sheet metal parts slide into the bottom of the accommodating groove 31, and the sheet metal parts are uniformly distributed. When the support plate 30 rotates to the lower right of the rotating shaft 10, under the action of gravity, the push plate 63 slides downward along the connecting rod 61, the friction block 50 retracts into the accommodation hole 32, and the sheet metal parts on the receiving surface 33 of the support plate 30 can be sequentially slid onto the conveying belt 20 of the lower mesh belt conveyor and sent away.

[0058] In one embodiment, the accommodation hole 32 is strip-shaped, the length direction of the accommodation hole 32 coincides with the radial direction of the rotating shaft 10, and the friction block 50 is strip-shaped.

[0059] In this embodiment, the strip-shaped friction block 50 is located in the strip-shaped accommodation hole 32, and the sheet metal parts falling from the upper conveying belt 21 slide from one end of the support plate 30 away from the rotating shaft 10 to the rotating shaft 10. During this process, the sheet metal parts will contact the friction block 50 and be blocked, and the remaining sheet metal parts stacked on the sheet metal parts are sequentially slid and organized by the lower friction block 50, so that the overlapped sheet metal parts are sequentially distributed along the length direction of the friction block 50, and the sheet metal parts are uniformly distributed on the receiving surface 33. When the subsequent sheet metal parts slide onto the conveying belt 20 of the mesh belt conveyor, they are also relatively uniform.

[0060] In one embodiment, the sheet metal part feeding device further comprises a plurality of strip-shaped protrusions 70. The plurality of strip-shaped protrusions 70 are sequentially arranged on the receiving surface 33 along the axial direction of the rotating shaft 10. The length direction of each strip-shaped protrusion is directed toward the rotating shaft 10. The length direction of the strip-shaped protrusion 70 is substantially consistent with the radial direction of the rotating shaft 10, specifically, the strip-shaped protrusion 70 in the middle of the receiving surface 33 extends along the radial direction of the rotating shaft 10; and the strip-shaped protrusions 70 on both sides of the middle strip-shaped protrusion 70 on the receiving surface 33 are inclined, and the end of the strip-shaped protrusion 70 away from the rotating shaft 10 is inclined to the middle of the length direction of the support plate 30.

[0061] In this embodiment, when the sheet metal parts fall from above onto the strip-shaped protrusions 70 on the support plate 30, the overlapped sheet metal parts are separated by the strip-shaped protrusions 70, so that the sheet metal parts can be uniformly distributed in the length direction of the support plate 30, and the length direction of the support plate 30 is substantially the same as the width of the conveying belt 20 below, which makes the subsequent sheet metal parts fall from the support plate 30 to the conveying belt 20 and be uniformly distributed in the width direction of the conveying belt 20.

[0062] In one embodiment, the strip-shaped protrusion 70 has an inclined surface on the end away from the rotating shaft 10. The inclined surface of the strip-shaped protrusion 70 is in contact with the receiving surface 33, and the sheet metal part first contacts the end of the support plate 30 away from the rotating shaft 10 when falling from above, and then the sheet metal part slides along the support plate 30. During this process, when the overlapped sheet metal part passes through the inclined surface of the strip-shaped protrusion 70, part of the overlapped sheet metal part slides along the inclined surface of the strip-shaped protrusion 70 and then tilts after appearing above the strip-shaped protrusion 70, so that the overlapped sheet metal part is misaligned and separated, thereby making the sheet metal part uniformly distributed in the length direction of the support plate 30.

[0063] In one embodiment, the sheet metal part feeding device further comprises two mounting plates 80 arranged on the mesh belt conveyor, and the two mounting plates 80 are symmetrically arranged. The two mounting plates 80 are provided with coaxial mounting holes, and the rotating shaft 10 is rotatably arranged in the two mounting holes. The driving mechanism 40 is a motor, the motor is connected with one of the two mounting plates 80, and the output end of the motor is connected with the rotating shaft 10. The two mounting plates 80 are located outside the two ends of the plurality of support plates 30. The two mounting plates 80 close the two ends of the accommodating grooves 31, thereby avoiding the sheet metal part from sliding off from the two sides of the accommodating grooves 31.

However, it can be understood that the embodiments of the utility model can be practiced without these specific details.
