Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection, in particular to a pesticide granule coating method production line finished product detection device. BACKGROUND

[0002] The pesticide granule coating method is a processing technology that improves the performance of granules by wrapping a specific functional layer (coating material) on the surface of pesticide granules. The essence of the coating method is to use mechanical force, adhesion or chemical reaction to uniformly attach the coating material to the surface of the base granules (core granules containing pesticide active ingredients), forming one or more continuous films that can isolate the core granules from the external environment (such as air, moisture, light), reduce the decomposition of active ingredients, control the release speed of active ingredients (slow-release effect), prolong the effective period, mask the peculiar smell of pesticides, reduce toxicity, improve the safety of use, and improve the physical properties of granules (such as wear resistance and flowability).

[0003] The patent document with publication number CN115372374B proposes a pesticide granule coating method production line finished product detection device. The front end feeding assembly is used to feed the granule tablets to be detected. The granule tablets to be detected fed by the front end feeding assembly can be arranged in a horizontal placement state one by one. The horizontal placement state of the granule tablets to be detected is continuously conveyed, and then changes to a vertical placement state after passing through the guide assembly. The rear end feeding assembly is connected to the outlet of the guide assembly to receive the granule tablets to be detected in a vertical placement state. Finally, the vertical placement state of the granule tablets to be detected is clamped by the clamping member according to batches, and moved to the clamping member on the placement table. The ultraviolet camera above the placement table can capture the entire placement table of the granule tablets to be detected in a vertical placement state. In this way, the granule tablets to be detected do not need to be placed in a specific position by humans, which is more convenient and ensures that the ultraviolet camera can irradiate the entire placement table of the granule tablets to be detected in a vertical placement state. At the same time, the step of manually removing the granule tablets to be detected from the detection carrier can be omitted, reducing the risk of contamination of the detection object caused by secondary contact.

[0004] However, the above detection device arranges the granules one by one in a horizontal placement state, and then places the granule tablets vertically. The number of parts to be placed is large, the speed of executing the placement is slow, and the detection efficiency is low. SUMMARY

[0014] Optionally, the detection member comprises a gantry fixedly installed on the top of the conveying frame, a detection shooting device fixedly installed on the top of the gantry, and the bottom surface of the detection shooting device is parallel to the conveying belt between the third roller and the first roller.

[0015] Optionally, the tower-shaped wind blade, the air guide flat nozzle, the fixed cylinder and the strip-shaped port form a horizontally placed tower-shaped fan, the strip-shaped port is an air inlet, and the air guide flat nozzle is an air outlet.

[0019] 1. When the granules on the conveying belt are stacked, the air guide flat nozzle guides the wind direction to form horizontal wind. Since the conveying belt at this position is inclined, the air guide flat nozzle cannot blow the granules at the bottom layer, the wind blows the stacked granules apart to lay flat, avoids the mutual obstruction and shielding of the granules, and at the same time, the wind blows the granules to impact the intercepting net to drive the sliding block to move the toothed plate, the toothed plate drives the toothed knurled knob switch to rotate, accelerates the rotation speed of the motor, that is, accelerates the moving speed of the conveying belt.

When the toothed knurled knob switch accelerates the moving speed of the conveying belt, the hydraulic telescopic rod is extended to reduce the opening of the air port baffle, increase the suction, and reduce the rolling speed of the granules, so as to avoid the problem that the granules roll too fast from the detection shooting device and cannot be clearly shot due to the increase of the moving speed of the conveying belt.

[0021] 3. The multiple positioning blocks are designed to position the sliding block at different gears, avoid the frequent sliding of the sliding block, the continuous movement of the toothed plate to rotate the toothed knurled knob switch, and the frequent adjustment of the rotating speed of the conveying belt to cause abrasion.

[0037] Example 1

[0038] This embodiment proposes a finished product testing device for a pesticide granule coating production line, such as... Figure 1 As shown, the system includes a conveyor frame 1, a feeding funnel 2 fixedly mounted on the top of the conveyor frame 1, and a conveyor belt 3 for conveying granules rotatably connected to the middle of the conveyor frame 1. Granules fall through the feeding funnel 2 onto the conveyor belt 3, which then moves the granules.

[0039] like Figure 2 and Figure 7 As shown, a deceleration mechanism 5 is provided on the top of the conveyor frame 1. The deceleration mechanism 5 includes a detection component, which includes a gantry frame 54. The gantry frame 54 is fixedly installed on the top of the conveyor frame 1. A detection imaging device 55 is fixedly installed on the top of the gantry frame 54. The detection imaging device 55 is a conventional granule detection device in the prior art.

[0040] like Figure 3 and Figure 5As shown, a flattening mechanism 4 is provided on the top of the conveyor frame 1. The flattening mechanism 4 includes a support plate 41, which is fixedly installed on the top of the conveyor frame 1. A tower-type fan blade 42 is rotatably connected to the support plate 41. A horizontal air guide nozzle 411 is fixedly installed at the bottom of the support plate 41. A first roller 48 and a second roller 49 supporting the conveyor belt 3 are rotatably connected inside the conveyor frame 1. The conveyor belt 3 between the first roller 48 and the second roller 49 is inclined. There is an angle between the bottom of the air guide nozzle 411 and the conveyor belt 3.

[0041] The tower fan blades 42 generate airflow that blows out from the air guide nozzles 411. The height difference between the air outlet of the air guide nozzles 411 and the conveyor belt 3 is the same as the height of one layer of granules. The air guide nozzles 411 guide the airflow to form a horizontal wind. Since the conveyor belt 3 is inclined at this position, the air guide nozzles 411 cannot reach the bottom layer of granules. The wind blows the granules that are piled together apart and spreads them out, preventing the granules from piling up together and obstructing each other, which would affect the detection and imaging device 55's detection of the granules. At the same time, the wind and the granules are in non-rigid contact, which avoids collisions that could damage the coating on the surface of the granules.

[0042] like Figure 4 As shown, the side plate 43 is slidably connected to an intercepting net 45 located in the air outlet direction of the air guide nozzle 411. The intercepting net 45 intercepts the blown particles. A support frame is fixedly installed at the edge of the intercepting net 45. The intercepting net 45 adopts a pocket-shaped structure. The inclined surface of the pocket-shaped structure reduces the speed at which the particles fall from the intercepting net 45, preventing damage to the coating on the particles after they fall. The side plate 43 is rotatably connected to a toothed rotary switch 410 that controls the conveying speed of the conveyor belt 3. A motor that is fixedly connected to the second roller 49 is fixedly installed inside the conveyor frame 1. The toothed rotary switch 410 is electrically connected to the motor. A transmission component is provided between the intercepting net 45 and the toothed rotary switch 410.

[0043] The transmission component includes a slider 44. Both ends of the interception net 45 are fixedly mounted with sliders 44. A toothed plate 47 is fixedly mounted on the bottom of the slider 44. The bottom of the toothed plate 47 is engaged with the toothed rotary switch 410. A support spring 46 is elastically connected between the slider 44 and the side plate 43.

[0044] When there is no granular material accumulation on the conveyor belt 3, the air blown out from the air guide nozzle 411 passes directly through the mesh of the intercepting net 45. When there is granular material accumulation on the conveyor belt 3, the granules are blown onto the intercepting net 45, and the impact of the granules on the intercepting net 45 causes the slider 44 to drive the toothed plate 47 to move. The toothed plate 47 drives the toothed knob switch 410 to rotate, increasing the rotation speed of the motor, that is, increasing the moving speed of the conveyor belt 3.

[0045] In this embodiment, when there is an accumulation of granules on the conveyor belt 3, the air guide nozzle 411 guides the airflow to form a horizontal wind. Since the conveyor belt 3 is inclined at this position, the air guide nozzle 411 cannot blow the granules at the bottom layer. The wind blows the granules piled together and spreads them out, avoiding the granules from blocking each other. At the same time, the wind blows the granules to impact the interception net 45, causing the slider 44 to drive the toothed plate 47 to move. The toothed plate 47 drives the toothed knob switch 410 to rotate, increasing the rotation speed of the motor, that is, increasing the moving speed of the conveyor belt 3. With the granules falling at the feeding funnel 2 at a constant speed, the granules on the conveyor belt 3 are more sparsely distributed, avoiding the granules from blocking each other and affecting the detection.

[0046] Example 2

[0047] Based on Example 1, this example proposes a finished product testing device for a pesticide granule coating production line, such as... Figure 7 and Figure 8 As shown, the deceleration mechanism 5 also includes a third roller 51, which is rotatably connected to the inner wall of the conveyor frame 1. The conveyor belt 3 between the third roller 51 and the first roller 48 is inclined, and the granules roll on the conveyor belt 3 at this position, so that the detection and imaging device 55 can detect the granules more comprehensively.

[0048] like Figure 9 As shown, a fixed cylinder 52 is fixedly installed at the bottom of the support plate 41. The side of the fixed cylinder 52 is fixedly connected to the air guide nozzle 411. A strip-shaped opening 53 is provided on the fixed cylinder 52. The air suction direction of the strip-shaped opening 53 is parallel to the conveyor belt 3 between the third roller 51 and the first roller 48. An air vent baffle 57 is slidably connected inside the fixed cylinder 52 and located at the strip-shaped opening 53. A hydraulic telescopic rod 58 is fixedly installed inside the fixed cylinder 52. The end of the hydraulic telescopic rod 58 is fixedly connected to the air vent baffle 57. A manual hydraulic pump 56 is fixedly installed on the side of the strip-shaped opening 53. A hydraulic hose 59 is fixedly installed between the manual hydraulic pump 56 and the hydraulic telescopic rod 58.

[0049] The hydraulic telescopic rod 58 extends to slide the air outlet baffle 57, changing the opening size of the strip-shaped outlet 53, thereby increasing the suction at the fixed cylinder 52. The tower fan blade 42, the air guide flat nozzle 411, the fixed cylinder 52 and the strip-shaped outlet 53 form a horizontal tower fan. The strip-shaped outlet 53 is the air inlet and the air guide flat nozzle 411 is the air outlet. The suction at the fixed cylinder 52 is used to reduce the rolling speed of the granules.

[0050] When the slider 44 moves and the toothed plate 47 rotates the toothed knob switch 410 to accelerate the movement speed of the conveyor belt 3, the slider 44 moves to squeeze the manual hydraulic pump 56 to squeeze the hydraulic oil inside into the hydraulic telescopic rod 58, causing it to extend. Therefore, when the movement speed of the conveyor belt 3 increases, the extension of the hydraulic telescopic rod 58 causes the air outlet baffle 57 to reduce the opening of the strip-shaped opening 53, increase the suction force, and reduce the rolling speed of the granules, so as to reduce the situation where the granules cannot be clearly captured because the movement speed of the conveyor belt 3 increases and the granules roll quickly from the detection and imaging device 55.

[0051] In this embodiment, the conveyor belt 3 between the third roller 51 and the first roller 48 is inclined. The granules roll on the conveyor belt 3 at this position, so that the detection and imaging device 55 can detect the granules more comprehensively. When the toothed knob switch 410 increases the moving speed of the conveyor belt 3, the hydraulic telescopic rod 58 extends to reduce the opening of the strip-shaped opening 53 of the air vent baffle 57, increase the suction force, and reduce the rolling speed of the granules. This avoids the problem that the granules cannot be clearly captured because the moving speed of the conveyor belt 3 increases and the granules roll too fast from the detection and imaging device 55.

[0052] Example 3

[0053] Based on Embodiment 1 or 2 above, this embodiment proposes a finished product testing device for a pesticide granule coating production line, such as... Figure 6 As shown, a positioning mechanism 6 is provided inside the side plate 43. The positioning mechanism 6 includes a sliding groove 63. Multiple sliding grooves 63 are provided and are distributed equidistantly along the side plate 43 in a straight line. A positioning block 62 is slidably connected inside the sliding groove 63. A spring sheet 64 is elastically connected between the bottom of the positioning block 62 and the side plate 43. A positioning groove 61 is provided at the bottom of the slider 44, and the positioning groove 61 is engaged with the positioning block 62.

[0054] The positioning block 62 is inserted into the positioning groove 61 to fix the slider 44 and prevent the slider 44 from sliding frequently. The spring plate 64 deforms when the positioning block 62 is squeezed by the slider 44, so that the positioning block 62 slides into the slide groove 63.

[0055] The bottom corner of the slider 44 has a rounded corner 65, the curvature of which is the same as that of the positioning block 62. The rounded corner 65 reduces the friction between it and the positioning block 62. There is a gap between the top of the positioning block 62 and the support spring 46 to prevent the positioning block 62 from hindering the deformation of the support spring 46.

[0056] In this example, the design of multiple positioning blocks 62 is used to position the slider 44 at different positions, avoiding frequent sliding of the slider 44, which would cause the toothed plate 47 to move continuously and rotate the toothed knob switch 410, resulting in frequent speed adjustments of the conveyor belt 3 and wear.

[0057] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
