Description

Technical Field

[0001] This utility model relates to the technical field of material rejection devices, and in particular to a dual-channel chain plate lifting rejection mechanism. Background Technology

[0002] The rejection mechanism is typically located behind the inspection mechanism. When the inspection mechanism detects normal materials, the materials are directly transferred to the rejection mechanism for further flow. However, when the inspection mechanism detects abnormal materials, the entire rejection mechanism's channel needs to be flipped, turning the material into a transfer box and rejecting the abnormal material. During this flipping process, normal materials in the channel are also screened out and turned into the transfer box, reducing the accuracy of abnormal material rejection and increasing production costs.

[0003] To address this, a dual-channel chain plate lifting rejection mechanism is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a dual-channel chain plate lifting rejection mechanism, which aims to solve or improve at least one of the above-mentioned technical problems.

[0008] Two lifting mechanisms are provided, each corresponding to one of the two mesh conveyor belts. The lifting mechanisms drive the feed end of the mesh conveyor belt to lift or fall obliquely upwards, thereby creating a gap between the feed end of the mesh conveyor belt and the discharge end of the main conveyor belt, or connecting the feed end of the mesh conveyor belt with the discharge end of the main conveyor belt.

[0009] Preferably, the lifting mechanism includes a second drive assembly and a flap, the middle of the side wall of the flap is rotatably connected to the frame, the flap is located in the inner ring of the mesh conveyor belt and supported at the feed end of the mesh conveyor belt, the top of the flap is in sliding contact with the inner ring of the mesh conveyor belt, and the second drive assembly drives the flap to rotate, thereby causing the feed end of the mesh conveyor belt to be lifted obliquely upward or lowered.

[0010] Preferably, the second drive assembly includes a drive cylinder hinged to the frame, and the push rod of the drive cylinder is hinged to the bottom of the side wall of the flap.

[0011] Preferably, a driven shaft is rotatably connected to the frame, four driven sprockets are fixedly connected to the driven shaft, two chains are fixedly connected to the mesh conveyor belt, and the four chains on the two mesh conveyor belts respectively mesh with the four driven sprockets; the driven shaft is located at the discharge end of the mesh conveyor belt.

When the material is detected as normal, the feed end of the mesh conveyor belt aligns with the discharge end of the main conveyor belt, and the material is directly conveyed from the main conveyor belt to the mesh conveyor belt.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-3 This utility model provides a dual-channel chain plate lifting rejection mechanism, comprising:

[0025] Rack 1;

[0026] Two sets of conveying mechanisms, each conveying mechanism including a first drive assembly mounted on the frame 1, on which a mesh chain conveyor belt 2 is conveyed, and the two mesh chain conveyor belts 2 are arranged side by side at the discharge end of the main conveyor belt;

[0027] Two lifting mechanisms are respectively set one-to-one with two mesh conveyor belts 2. The lifting mechanisms drive the feed end of the mesh conveyor belt 2 to be raised or lowered at an angle, thereby creating a gap between the feed end of the mesh conveyor belt 2 and the discharge end of the main conveyor belt, or connecting the feed end of the mesh conveyor belt 2 with the discharge end of the main conveyor belt.

[0028] A receiving frame is installed below the discharge end of the main conveyor belt and the feed end of the mesh conveyor belt 2 to collect rejected materials. A gap exists between the feed end of the mesh conveyor belt 2 and the discharge end of the main conveyor belt when they are connected, preventing mutual interference. Figure 1 As shown, of the two mesh conveyor belts 2, one is in a downward state and the other is in an upward state.

[0029] The frame 1 is the mounting carrier of the entire mechanism, serving as the mounting platform for all components, and everything else is mounted on it.

[0030] Material on the main conveyor belt is detected by a detection mechanism. When the material is detected as normal, the feed end of the mesh conveyor belt 2 connects with the discharge end of the main conveyor belt, and the material is directly conveyed from the main conveyor belt to the mesh conveyor belt 2. When abnormal material is detected, the corresponding mesh conveyor belt 2 is lifted obliquely upwards by a lifting mechanism according to the location of the abnormal material, creating a gap between the feed end of the mesh conveyor belt 2 and the discharge end of the main conveyor belt. The abnormal material on the main conveyor belt falls through the gap into the receiving frame below for collection, while the normal material on the other side of the main conveyor belt is conveyed to another mesh conveyor belt 2, thereby achieving the rejection of abnormal material. This application reduces the probability of normal material being rejected and improves the accuracy of rejecting abnormal material by setting up a double mesh conveyor belt.

[0031] In some alternative embodiments, the lifting mechanism includes a second drive assembly and a flap 3. The middle of the side wall of the flap 3 is rotatably connected to the frame 1. The flap 3 is located in the inner ring of the mesh conveyor belt 2 and supported on the feed end of the mesh conveyor belt 2. The top of the flap 3 is in sliding contact with the inner ring of the mesh conveyor belt 2. The second drive assembly drives the flap 3 to rotate, thereby causing the feed end of the mesh conveyor belt 2 to be lifted obliquely upward or lowered.

[0032] In some alternative embodiments, the second drive assembly includes a drive cylinder 4 hinged to the frame 1, the push rod of the drive cylinder 4 being hinged to the bottom of the side wall of the flap 3.

[0033] The drive cylinder 4 is the power source for the rejection action. The drive cylinder 4 is controlled by the detection host of the detection mechanism. When abnormal materials need to be rejected, the detection host controls the control solenoid valve of the drive cylinder 4 at the corresponding position, so as to extend the drive cylinder 4 and drive the flap 3 from the inclined state to the vertical state, thereby creating a gap between the mesh conveyor belt 2 and the main conveyor belt. The material falls from the gap into the receiving frame, realizing the precise rejection action. After rejection, the drive cylinder 4 returns, driving the flap 3 from the vertical state to the inclined state, so that the mesh conveyor belt 2 connects with the main conveyor belt, and the subsequent material is conveyed normally.

[0034] In some alternative embodiments, a driven shaft 5 is rotatably connected to the frame 1, four driven sprockets are fixedly connected to the driven shaft 5, two chains are fixedly connected to the mesh conveyor belt 2, and the four chains on the two mesh conveyor belts 2 respectively mesh with the four driven sprockets; the driven shaft 5 is located at the discharge end of the mesh conveyor belt 2.

[0035] In some alternative embodiments, the first drive assembly includes a drive shaft 6 rotatably connected to the frame 1, a drive motor 7 fixedly connected to the frame 1, and the output shaft of the drive motor 7 fixedly connected to the drive shaft 6; four drive sprockets are fixedly connected to the drive shaft 6, and four chains on the two mesh conveyor belts 2 respectively mesh with the four drive sprockets; the drive shaft 6 is located between the flip plate 3 and the driven shaft 5, and the drive shaft 6 is located below the driven shaft 5 and the top of the flip plate 3.

[0036] In some alternative embodiments, a first steering shaft 8 is rotatably connected to the frame 1. The first steering shaft 8 is located above the drive shaft 6 and between the drive shaft 6 and the flap 3. The drive shaft 6 is located on the inner ring of the mesh conveyor belt 2, and the first steering shaft 8 is located on the outer ring of the mesh conveyor belt 2 and slides in contact with the outer wall of the mesh conveyor belt 2. The mesh conveyor belt 2 between the flap 3 and the first steering shaft 8 has a downward curved section under the action of gravity.

[0037] This design allows for some adjustment of the mesh conveyor belt 2 at the curved section, preventing it from being in a taut, tense state and facilitating its upward and downward movement as the flap 3 rotates. The first steering shaft 8 ensures the wrap angle between the chain and the drive sprocket, guaranteeing proper meshing.

[0038] In some alternative embodiments, a second steering shaft 9 is rotatably connected to the frame 1. The second steering shaft 9 is located inside the arc-shaped section on the mesh conveyor belt 2, and the second steering shaft 9 slides in contact with the inner ring of the mesh conveyor belt 2.

[0039] By positioning the first steering shaft 8, the second steering shaft 9, the drive shaft 6, and the driven shaft 5, the chain on the mesh conveyor belt 2 maintains a certain tension when meshing with the drive and driven sprockets, thus improving the meshing effect. The drive motor 7 provides power, causing the drive shaft 6 to rotate, thereby driving the mesh conveyor belt 2 to move.

[0040] The frame 1 is welded from stainless steel parts and serves as the base for the support frame and the installation of all other parts. Support rod structures are designed on it according to the position of the mesh conveyor belt 2 around each rotating shaft to increase the strength of the frame and at the same time ensure that the mesh conveyor belt 2 does not interfere with other moving parts.

[0041] In some alternative embodiments, the conveying speed of the mesh conveyor belt 2 is consistent with the conveying speed of the main conveyor belt.

[0042] In use, the material on the main conveyor belt is detected by the detection mechanism. When the material is detected as normal, the feed end of the mesh conveyor belt 2 connects with the discharge end of the main conveyor belt, and the material is directly conveyed from the main conveyor belt to the mesh conveyor belt 2. When abnormal material is detected, the detection mechanism controls the corresponding drive cylinder 4 to rotate, causing the flap 3 to rotate from an inclined state to a vertical state, creating a gap between the feed end of the mesh conveyor belt 2 and the discharge end of the main conveyor belt. The abnormal material on the main conveyor belt falls through the gap into the receiving frame below for collection. Meanwhile, the normal material on the other side of the main conveyor belt is conveyed to another mesh conveyor belt 2, thus removing the abnormal material. After removal, the detection mechanism controls the corresponding drive cylinder 4 to return, causing the flap 3 to change from a vertical state to an inclined state, connecting the mesh conveyor belt 2 with the main conveyor belt, and subsequent material is conveyed normally.

[0043] When abnormal material detection results are found, this application can separate the abnormal material into a specific area, and the corresponding rejection mechanism in this area can reject the abnormal material, thereby reducing the carry-out of normal material.
