Description

Technical Field

[0001] This utility model relates to a discharge device for a screening machine, and more particularly to a quantitative packing and discharge device for a screening machine. Background Technology

[0002] Existing optical image sorting machines transport qualified products to a receiving box via a feeding channel. After sorting is completed and the machine is stopped, the receiving box is removed. Based on this, the customer proposed a quantitative collection requirement. However, the feeding channel feeds continuously with short intervals between adjacent qualified products, and the receiving box needs to be replaced quickly. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a quantitative packing and discharging device for a screening machine, which can transfer the quantitatively collected receiving box in the box-moving process without affecting the material receiving at the packing station.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the quantitative packing and discharging device of the screening machine includes a packing station and a box-moving station. The packing station is equipped with a material discharge channel with an inclined discharge end. An infeed conveyor belt connects the packing station and the box-moving station. The box-moving station is equipped with a box-moving assembly, which is connected to an outfeed conveyor belt. The box-moving assembly includes two lifting box-moving arms.

[0005] In this scheme, after the quantitative packing is completed, the inbound conveyor belt moves the receiving box to the box transfer station. When the next receiving box arrives at the packing station, the box transfer arm catches the receiving box and lowers to place the receiving box onto the outbound conveyor belt.

[0006] Preferably, both the infeed conveyor belt and the outfeed conveyor belt are equipped with side baffles on both sides.

[0007] In this design, the side baffles prevent the receiving box from tilting during transport.

[0008] Preferably, the material discharge channel is formed by a discharge conveyor belt and a discharge guide plate, wherein the discharge guide plate is inclined and the discharge conveyor belt is horizontal.

[0009] In this scheme, qualified products form a queue on the discharge conveyor belt with a fixed spacing, which makes it easy to determine the conveying speed of the infeed conveyor belt.

[0010] Preferably, the feeding end of the material discharge channel is equipped with an air nozzle, the air nozzle is rotated and adjusted on the mounting block, the mounting block is connected to a mounting rod, the mounting rod is raised and lowered and adjusted on the mounting plate, the conveying direction of the material discharge channel is defined as longitudinal, and the longitudinal movement adjustment of the mounting plate is set on the mounting frame.

[0011] In this design, the air nozzle is rotated, the mounting rod is raised and lowered, and the mounting plate is moved longitudinally to accommodate different sizes of screening objects.

[0012] Preferably, the packing station is equipped with lifting baffle blocks.

[0013] In this scheme, after the receiving box arrives at the packing station, the retaining block rises, and the next receiving box comes into contact with the retaining block to complete the conveying process.

[0014] Preferably, the conveying direction of the infeed conveyor belt is defined as longitudinal, and the side baffle is configured for lateral movement adjustment and lifting adjustment.

[0015] In this scheme, the side baffles are adjusted laterally and raised and lowered to adapt to different specifications of receiving boxes. Changes in the specifications of the objects being screened and the quantitative collection values ​​will affect the specifications of the receiving boxes.

[0016] Preferably, the outgoing conveyor belt is equipped with positioning blocks on both sides to define the conveying direction of the outgoing conveyor belt as longitudinal, and the positioning blocks are laterally movable.

[0017] In this design, the positioning blocks on both sides align the receiving boxes to prevent them from tilting during transport.

[0018] Preferably, the conveying direction of the box-in conveyor belt is defined as longitudinal, the box-moving station is equipped with a positioning stop bar, the positioning stop bar extends laterally, and the positioning stop bar is longitudinally adjustable.

[0019] In this solution, the material receiving box comes into contact with the positioning stop bar to ensure proper conveying. The positioning stop bar can be adjusted longitudinally to accommodate different sizes of material receiving boxes, eliminating the need to adjust the box-moving arm.

[0020] The beneficial effects of this utility model are as follows: After the quantitative packing is completed, the infeed conveyor belt moves the receiving box to the box-shifting station. When the next receiving box arrives at the packing station, the box-shifting arm catches the receiving box and lowers to place it onto the outfeed conveyor belt. After the receiving box arrives at the packing station, the box-stopping block rises to block the next receiving box, creating a certain distance between them and controlling the arrival speed of the next receiving box. When the next receiving box arrives at the packing station, the receiving box at the box-shifting station is at a distance from it, preventing interference. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0031] See appendix Figure 1-5In this embodiment, a quantitative packing and discharging device for a screening machine includes a packing station and a packing transfer station. The packing station is equipped with a discharge channel 1, which has an inclined discharge end. The discharge channel 1 is formed by a discharge conveyor belt 8 and a discharge guide plate 9. The discharge guide plate 9 is inclined, and the discharge conveyor belt 8 is horizontal. The inlet end of the discharge channel 1 is equipped with an air nozzle 10. The air nozzle 10 is rotatably adjustable on a mounting block 2. The mounting block 2 is connected to a mounting rod 11, which is vertically adjustable on a mounting plate 12. The conveying direction of the discharge channel 1 is defined as longitudinal. The mounting plate 12 is longitudinally adjustable on a mounting frame 13. The packing station is equipped with a lifting baffle block 14.

[0032] A box-in conveyor belt 3 connects the box-packing station and the box-moving station. The box-moving station is equipped with a box-moving assembly 4 and a positioning stop bar 16. The box-moving assembly 4 is connected to a box-out conveyor belt 5. The box-moving assembly 4 includes two lifting box-moving arms 6. Side baffles 7 are provided on both sides of the box-in conveyor belt 3 and the box-out conveyor belt 5, defining the conveying direction of the box-in conveyor belt 3 as longitudinal. The side baffles 7 are laterally adjustable and height adjustable. The positioning stop bar 16 extends laterally and is longitudinally adjustable. Positioning blocks 15 are provided on both sides of the box-out conveyor belt 5, defining the conveying direction of the box-out conveyor belt 5 as longitudinal. The positioning blocks 15 are laterally adjustable.

[0033] In this embodiment, the operator places the receiving boxes at intervals on the infeed conveyor belt 3. After the receiving box reaches the packing station, the baffle block 14 rises, and the next receiving box comes into contact with the baffle block 14 to be in place. After the quantitative packing is completed, the baffle block 14 falls, and the infeed conveyor belt 3 transports two receiving boxes to their respective positions. The baffle block 14 rises, and the infeed conveyor belt 3 continues to transport until the next receiving box comes into contact with the baffle block 14. The box-moving arm 6 catches the receiving box delivered by the infeed conveyor belt 3. After the next receiving box is in place, the box-moving arm 6 falls and places the receiving box on the outfeed conveyor belt 5. The outfeed conveyor belt 5 sends the receiving box out, and the positioning block 15 aligns the stopped receiving boxes.

[0034] The air nozzle 10 blows the qualified products delivered by the turntable into the material discharge channel 1, which is a mature technology.

[0035] In this system, a photoelectric sensor can be installed at the packing station to detect the receiving box. Once the receiving box is in place, the baffle block 14 will rise. The confirmation of quantitative packing can be achieved by calculating the dropping time. After the last qualified product is blown into the dropping channel 1 by the air nozzle 10, the box conveyor belt 3 and the baffle block 14 will move after a certain dropping time. The dropping time can be determined by the conveying speed of the discharge conveyor belt 8 and the dropping speed of the discharge guide plate 9. The arrival monitoring of the receiving box at the baffle block 14 can be achieved by using a pressure sensor or visual inspection.

[0036] The rotation adjustment of the air nozzle 10 is specifically as follows: unscrew the fastener, rotate the air nozzle 10 relative to the mounting block 2, and tighten the fastener again after it is rotated to the correct position. The mounting block 2 has a through hole for the fastener to pass through, and the air nozzle 10 has a connecting hole for the fastener to connect. The mounting plate 12 has clamps, and the mounting rod 11 passes through between the clamps. One clamp is connected to a screw, and the other clamp has a through hole for the screw to pass through. A knob is threaded onto the screw. Rotating the knob tightens or loosens the two clamps to complete the fixing or adjustment of the mounting rod 11. The mounting plate 12 has an elongated hole, and the mounting bracket 13 has a connecting hole. The elongated hole is moved relative to the connecting hole, and then the fastener is passed through the elongated hole and connected to the connecting hole to complete the adjustment.

[0037] The baffle block 14 is driven by a cylinder; the two ends of the positioning baffle 16 are connected to sliders, which are connected to the cylinder. This allows for both buffering and adjustment by adding or releasing air, which moves the cylinder to drive the sliders. The cylinder output shaft is connected to a fixed block, allowing the cylinder to move relative to the fixed block. The side baffle 7 is connected to a mounting shaft, which passes through a mounting seat. An adjusting rod is threaded onto the mounting seat. Rotating the adjusting rod causes it to abut against the mounting shaft, restricting its axial movement (i.e., lateral movement). The same principle applies to lifting and lowering adjustments. The moving arm 6 is mounted on a lifting plate, which is connected to a cylinder. The cylinder output shaft is also connected to a fixed block, allowing the cylinder to move relative to the fixed block.

[0038] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
