DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0028] Example 1: See Figure 1 , 2As shown, a material distribution conveying device comprises a frame 1 and a conveyor belt 2 mounted on the frame 1, a material conveying channel 3 is provided on the frame 1 above the conveyor belt 2, and a material pushing assembly is also provided on the frame 1, the material pushing assembly comprises a push plate 4, a driving cylinder 5 and a connecting mechanism, and the driving cylinder 5 is connected to the push plate 4 via the connecting mechanism;

[0029] The connecting mechanism includes a connecting plate 6 and two connecting rods 7, the front end of the connecting plate 6 is connected to the frame 1 for rotation, the push plate 4 is arranged parallel to the left side of the connecting plate 6, the driving cylinder 5 is arranged on the right side of the connecting plate 6, the front end of the driving cylinder 5 is connected to the frame 1 for rotation, the output shaft at the rear end of the driving cylinder 5 is connected to the rear end of the connecting plate 6 for rotation, the two connecting rods 7 are installed on the connecting plate 6, and the inner ends of the connecting rods 7 are connected to the push plate 4 vertically;

[0030] When the output shaft of the driving cylinder 5 extends, the push plate 4 is pushed to be set in the material conveying channel 3, and the push plate 4 is tilted from front to back and to the left;

[0031] When the output shaft of the driving cylinder 5 retracts, the pushing plate 4 is driven to rotate rightward and is disposed outside the material conveying passage 3 .

[0032] In this embodiment, the conveyor belt conveys the product from front to back in the material conveying channel. When passing the position of the push assembly, the output shaft of the drive cylinder extends to push the rear end of the connecting plate to move to the left. In this process, the connecting plate and the connecting rod drive the push plate to rotate toward the material conveying channel. Since the front end of the connecting plate is rotatably connected to the frame, the front end of the push plate will be close to the right end of the material conveying channel, and the rear end of the push plate will be close to the left end of the material conveying channel. In this process, the product is pushed to move to the left along the conveyor belt through the inclination of the push plate, and since the conveyor belt continues to convey backward, the product moves close to the left side of the material conveying channel, so that the product pushed by the push plate will be close to the left side of the material conveying channel. When this product is pushed to the left, the output shaft of the drive cylinder retracts, driving the push plate to rotate to the outside of the material conveying channel. At this time, the next product is conveyed close to the right end of the material conveyor belt and passes through the left side of the push plate, so that the product can be conveyed left and right at intervals to achieve the material separation action. The material separation speed is fast and the thrust is strong, which can push the material separation of heavy products, so that the material is transported in a single row in front of the push plate and in a double row in the back of the push plate. It does not require a high-power motor and the material separation speed is also fast.

[0033] In this embodiment, the driving cylinder is preferably a pneumatic cylinder, which has a fast driving speed and low cost.

[0034] When the output shaft of the driving cylinder extends, the front end of the connecting plate will not move due to the limitation of the front end of the connecting plate. However, since the front end of the connecting plate is connected to the frame in rotation, the front end of the driving cylinder is also connected to the frame in rotation, and the output shaft at the rear end of the driving cylinder is connected to the rear end of the connecting plate in rotation. In this way, during the extension of the output shaft of the driving cylinder, the rear end of the connecting plate will be pushed to rotate to the left, that is, the connecting plate will be pushed to rotate counterclockwise around the frame. During the counterclockwise rotation of the connecting plate, the connecting rod will also rotate counterclockwise, thereby driving the push plate to rotate counterclockwise through the connecting rod, so that the push plate is tilted and the product is pushed to move to the left. In addition, during the tilting of the push plate, the product will gradually be pushed to move to the left, and since the conveyor belt will also drive the product to move backward, during the tilting of the push plate, the product will move obliquely toward the left rear to achieve material distribution. In addition, compared with the method of pushing materials perpendicular to the conveyor belt, the product will not be pushed down, ensuring the stability and smoothness of the pushing.

[0035] See also Figure 1 , 2 As shown, a notch 8 communicating with the material conveying passage 3 is provided on the right side wall of the frame 1 , and when the output shaft of the driving cylinder 5 retracts, the push plate 4 is arranged in the notch 8 .

[0036] By setting the notch, when the drive cylinder output shaft is driven, the push plate can be driven to enter the material conveying channel from the notch to push the product. When the drive cylinder output shaft retracts, the push plate is driven to retract into the notch, and also plays a role of covering the notch. In this way, when the drive cylinder output shaft does not extend and the product passes through the material conveying channel at the notch, the push plate also plays a role of limiting, preventing the product from falling out of the notch or being stuck by the notch.

[0037] See also Figure 1 , 2 As shown, the material conveying channel 3 includes a front channel 9, a connecting channel 10 and a rear channel 11. The right sides of the rear channel 11, the connecting channel 10 and the front channel 9 are arranged flush, and the width of the rear channel 11 is 2 to 3 times the width of the front channel 9; the two ends of the left side of the connecting channel 10 are respectively connected to the left side of the front channel 9 and the left side of the rear channel 11; the notch 8 is arranged on the right side of the connecting channel 10. A partition 12 is arranged in the middle of the rear channel 11, and the partition 12 is arranged parallel to the extension direction of the rear channel 11.

[0038] The partition divides the rear channel into two non-interfering channels, wherein the width of the front channel is slightly larger than the diameter of the product, so that when the product is transported from the front channel to the rear, multiple products are arranged in a row in the front channel. Each time a product is separated, the output shaft of the drive cylinder extends to drive the push plate to rotate once, that is, once, and the push plate pushes the product to the left. When the product enters the connecting channel from the front channel, the output shaft of the drive cylinder does not extend, and the product is directly transported to the right and rearward, and directly enters the rear channel on the right side of the partition. The product will enter the rear channel on the right side of the partition. When the next product enters the connecting channel from the front channel, the output shaft of the drive cylinder extends, driving the rear end of the push plate to tilt to the left. Since the product is set to the right at this time, the push plate will push the product to move to the left rear. When the output shaft of the drive cylinder is fully extended, the product moves to the left side of the rear end of the push plate. At this time, the product is facing the rear channel on the left side of the partition. The product will be sent to the rear channel on the left side of the partition by the conveyor belt. At the same time, the output shaft of the drive cylinder retracts, driving the push plate back into the gap, and the next product will enter the rear channel on the right side of the partition. The next product is pushed into the rear channel on the left side of the partition, and the cycle continues. Even if the product pushed by the push plate is not completely facing the rear channel on the left side, most of the product is facing the rear channel on the left side. When the product moves backward, its right side may touch the partition a little bit, and it will be blocked and limited by the front end of the partition. Due to the conveying force of the conveyor belt driving the product to move backward, the product will also pass through the combined action of the partition and the conveyor belt and move toward the rear channel on the left. In this embodiment, since the width of the rear channel is 2-3 times the width of the front channel, the right channel, the front channel and the right side of the connecting channel are flush, so that the front end of the left side of the connecting channel is connected to the rear end of the left side of the front channel, and the rear end of the left side of the connecting channel is connected to the front end of the left side of the rear channel, that is, the left side of the connecting channel is an inclined surface inclined from front to back and to the left, so that when the product is pushed by the push plate to move to the left rear, the left outer surface of the product will be as close to or in contact with the left side of the connecting channel as possible, and in the process of the output shaft of the driving cylinder extending, the distance between the left side of the push plate and the left side of the connecting channel will be slightly larger than the size of the product, so that the product will be restricted by the left side of the connecting channel and the left side of the push plate, and will not fall over. Even if the output shaft of the driving cylinder extends at a relatively fast speed, it will not fall over, thereby ensuring the stability of the material distribution. After the material distribution, the rear channels on both sides of the partition convey the two rows of products respectively, and the rear end adjusts the conveying trajectory of the two rows of materials, so that the two sides can be fed separately.

[0039] See also Figure 1 , 2As shown, the front and rear ends of the push plate 4 are respectively provided with a front guide plate 13 and a rear guide plate 14. The front guide plate 13 is arranged to tilt from back to front and to the right, and the rear guide plate 14 is arranged to tilt from front to back and to the right.

[0040] The front guide plate and the rear guide plate play a guiding role to prevent the front end of the push plate from getting stuck with the product when the push plate enters the material conveying channel. The existence of the rear guide plate allows the push plate to separate from the product when the output shaft of the drive cylinder retracts and drives the push plate to move to the right, preventing the right end of the push plate from hooking the product.

[0041] See also Figure 1 , 2 As shown, the front end of the connecting plate 6 is rotatably connected to the frame 1 via the first connecting shaft 15, and the front end of the driving cylinder 5 is rotatably connected to the frame 1 via the second connecting shaft 16. The first connecting shaft 15 and the second connecting shaft 16 are arranged outside the right side of the material conveying channel 3, and the first connecting shaft 15 is arranged on the left side of the second connecting shaft 16. The straight line formed by the first connecting shaft and the second connecting shaft is arranged perpendicular to the moving direction of the conveyor belt.

[0042] See also Figure 1 , 2 As shown, an extension plate 17 extending to the right is provided on the top rear side of the connecting plate 6 , and the output shaft of the driving cylinder 5 is rotatably connected to the right end of the extension plate 17 .

[0043] The provision of the extension plate facilitates the connection between the drive cylinder and the connection plate, so that the drive cylinder and the connection plate can be located on the same plane.

[0044] There are two parallel mounting holes (not shown in the figure) spaced apart at the front and rear of the connecting plate 6, the mounting holes are arranged perpendicular to the connecting plate, and the two ends of the mounting holes respectively pass through the left side and the right side of the connecting plate 6, the middle part of each connecting rod 7 is inserted into one of the mounting holes, and the left end of the connecting rod 7 is connected to the right end face of the push plate 4.

[0045] The installation holes are provided for the installation of the connecting rod and the connecting plate. At the same time, the driving cylinder is provided above the plane where the installation holes are located, so that the connecting rod and the driving cylinder will not interfere with each other.

[0046] A screw hole penetrating the top of the connecting plate 6 is provided at the top of at least one of the mounting holes, and a limiting bolt 18 is threaded in the screw hole. The bottom of the limiting bolt 18 abuts against the top outer surface of the corresponding connecting rod 7, and the limiting bolt 18 limits the connecting rod 7 in the mounting hole.

[0047] In this embodiment, a screw hole is provided at the top of a mounting hole, and the left sides of the two connecting rods are respectively connected to the right side of the push plate, and the connecting rods are respectively inserted into a mounting hole. After the limiting bolt locks and limits one connecting rod, the other connecting rod cannot move in the mounting hole, and the limiting quality can be ensured. At the same time, after the limiting bolt is loosened, the connecting rod can be taken out of the mounting hole to realize the disassembly of the push plate. At the same time, the connecting rod can also be moved to adjust the position of the push plate relative to the connecting plate, or according to the push plates of different thicknesses, it can be adjusted so that it pushes the product to the most suitable position, which is convenient for debugging.
