Description

Technical Field

[0001] The utility model relates to the technical field of production weighing equipment, and particularly relates to an online weighing and rejecting machine. Background Art

[0002] In the process of aquaculture, in order to ensure the smooth progress of aquaculture, it is necessary to regularly improve the bottom of the pond, improve the bottom environment of the pond, and adjust the water quality. When improving the bottom, it is necessary to pour specified amounts of additives such as quicklime and potassium monopersulfate compound salt into the pond.

[0003] Currently, when producing additives, an online weighing and rejecting machine is required to detect the single-pack weight of the additives. When the single-pack weight is inconsistent with the preset weight, the push plate will be controlled to push down the non-compliant products. Currently, the surface of the conveyor belt of the weighing and rejecting machine is relatively wide, and the products cannot be accurately located in the middle position when being conveyed to the surface of the conveyor belt, which easily leads to inaccurate measurement results, affecting the weighing effect. Moreover, after the products are pushed out, the products fall from a relatively high workbench, which easily causes damage to the packaging, increasing the production cost and having poor practicability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an online weighing and rejecting machine to solve the above problems, as described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An online weighing and rejecting machine provided by the utility model includes a weighing table. Both sides of the upper end of the weighing table are fixedly connected with cross plates. Both ends between the two cross plates are rotatably connected with rollers. The two rollers are传动连接 by a conveyor belt. One end of one of the cross plates is fixedly installed with a motor for driving the roller to rotate. A weighing device is fixedly installed between the two cross plates, and the contact surface of the weighing device abuts against the upper side of the conveyor belt. The ends of the two cross plates are fixedly installed with mounting seats. A vertical shaft is rotatably connected in the mounting seat. One side of the vertical shaft is fixedly connected with a guide plate, and an elastic structure for driving the guide plate to rotate away from the middle side of the weighing table is provided at the lower end of the mounting seat. Adjusting components for driving the guide plate to adjust the rotation angle are provided at the ends of the upper surfaces of the two cross plates;

[0007] A general controller is fixedly installed on one side of the weighing table. A cylinder is fixedly installed at the other end of one of the cross plates. The movable end of the cylinder is fixedly connected with a push plate. A C-shaped frame is fixedly connected to the other side of the weighing table. A main board corresponding to and adapted to the push plate is provided above the C-shaped frame. One side of the main board is rotatably connected with a swing plate, and a buffer component for slowly lowering the main board is provided at the upper end of the C-shaped frame.

[0008] When using the above-mentioned online weighing and rejection machine, during operation, the adjusting component drives the two guide plates to deflect at an angle against the elastic force of the elastic structure, so that the ends of the two guide plates are located in the middle of the surface of the conveyor belt. When the product is conveyed to the surface of the conveyor belt, it contacts the two guide plates and is positioned in the middle of the conveyor belt. Subsequently, when passing through the weighing device, the weight of the product is weighed, and the data is sent into the main controller for reading and comparison. When the data does not match, the control cylinder drives the push plate to move, and finally the product is pushed out of the conveyor belt. At this time, the product falls onto the main board and the swing plate, and falls under the action of gravity. At the same time, it slowly falls through the buffer component, and drives the swing plate to flip downward during the falling process, so that the product drops, completing the buffering.

[0009] Preferably, the elastic structure includes a circular plate fixedly connected to the lower end of the vertical shaft. A clockwork spring is sleeved on the lower end of the vertical shaft, and both ends of the clockwork spring are connected to the vertical shaft and the circular plate respectively.

[0010] Preferably, the adjusting component includes a threaded sleeve fixedly connected to the upper end surface of the cross plate. A screw rod is threadedly connected in the threaded sleeve, and the end of the screw rod is detachably connected to the guide plate through a hanging structure.

[0011] Preferably, the hanging structure includes a T-shaped rod rotatably connected to the end of the screw rod. A horizontal groove adapted to the T-shaped rod is formed through the guide plate.

[0012] Preferably, the buffer component includes two sliding rods fixedly connected to the upper end surface of the C-shaped frame. Sliding sleeves sleeved with the sliding rods are fixedly connected to both sides of the main board. A spring is connected between the sliding sleeve and the upper end surface of the C-shaped frame, and the spring is sleeved outside the sliding rod.

[0013] Preferably, two elastic bands are connected between the main board and the swing plate.

[0014] Preferably, the output end of the weighing device is electrically connected to the input end of the main controller, and the output end of the main controller is electrically connected to the input end of the cylinder.

[0015] The beneficial effects are as follows:

[0016] The adjusting component drives the two guide plates to deflect at an angle. When the product is conveyed to the surface of the conveyor belt, it contacts the two guide plates and is positioned in the middle of the conveyor belt. When the data does not match, the control cylinder drives the push plate to move, and finally the product is pushed out of the conveyor belt. At this time, the product falls onto the main board and the swing plate and falls, and at the same time, it slowly falls through the buffer component, and drives the swing plate to flip downward during the falling process, so that the product drops, completing the buffering, improving the weighing accuracy, and at the same time buffering the dropped product, avoiding damage to the product, and improving the practicability.

Specific embodiments

[0024] To make the objectives, technical solutions and advantages of the present invention clearer, the following will describe the technical solutions of the present invention in detail. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present invention.

[0025] See Figure 1-Figure 4As shown in the figure, the utility model provides an online weighing and rejecting machine, which includes a weighing table 1. Both sides of the upper end of the weighing table 1 are fixedly connected with cross plates 2. Both ends between the two cross plates 2 are rotatably connected with rollers 5. The two rollers 5 are drivingly connected through a conveyor belt 6. One end of one of the cross plates 2 is fixedly installed with a motor 7 for driving the roller 5 to rotate. A weighing device 8 is fixedly installed between the two cross plates 2, and the contact surface of the weighing device 8 abuts against the upper side of the conveyor belt 6. Mounting seats 12 are fixedly installed at the ends of the two cross plates 2. A vertical shaft 13 is rotatably connected in the mounting seat 12. One side of the vertical shaft 13 is fixedly connected with a guide plate 14, and an elastic structure for driving the guide plate 14 to rotate towards the side away from the middle of the weighing table 1 is arranged at the lower end of the mounting seat 12. Adjusting components 3 for driving the guide plate 14 to adjust the rotation angle are arranged at the ends of the upper surfaces of the two cross plates 2;

[0026] A total controller 9 is fixedly installed on one side of the weighing table 1. A cylinder 10 is fixedly installed at the other end of one of the cross plates 2. The movable end of the cylinder 10 is fixedly connected with a push plate 11. A U-shaped frame 15 is fixedly connected to the other side of the weighing table 1. A main board 16 corresponding and adapted to the push plate 11 is arranged above the U-shaped frame 15. A swing plate 17 is rotatably connected to one side of the main board 16, and a buffer component 4 for slowly lowering the main board 16 is arranged at the upper end of the U-shaped frame 15.

[0027] Refer to Figure 4 As shown in the figure, the elastic structure includes a circular plate 18 fixedly connected to the lower end of the vertical shaft 13. A clockwork spring 19 is sleeved on the lower end of the vertical shaft 13, and both ends of the clockwork spring 19 are respectively connected with the vertical shaft 13 and the circular plate 18. Due to the torsion of the clockwork spring 19, the vertical shaft 13 and the guide plate 14 can always rotate towards the side away from the middle of the weighing table 1, and can cooperate with the adjusting component 3 to adjust the angle of the guide plate 14.

[0028] As an optional implementation manner, the adjusting component 3 includes a threaded sleeve 3a fixedly connected to the upper surface of the cross plate 2. A screw rod 3b is threadedly connected in the threaded sleeve 3a. The end of the screw rod 3b is detachably connected to the guide plate 14 through a hanging structure. The hanging structure includes a T-shaped rod 3c rotatably connected to the end of the screw rod 3b. A transverse groove 3d adapted to the T-shaped rod 3c is penetrated and opened on the guide plate 14. Place the T-shaped rod 3c horizontally, rotate the guide plate 14 so that it passes through the T-shaped rod 3c through the transverse groove 3d, and then place the T-shaped rod 3c vertically. At this time, the guide plate 14 abuts against the end of the T-shaped rod 3c under the action of the elastic structure to complete the limit. By rotating the screw rod 3b to move it in the threaded sleeve 3a, the guide plate 14 is driven to adjust the angle through the T-shaped rod 3c, so as to better adapt to products of different specifications and sizes.

[0029] Refer to Figure 2As shown in the figure, the buffer assembly 4 includes two sliding rods 4b fixedly connected to the upper end surface of the C-shaped frame 15. Sliding sleeves 4a sleeved on the sliding rods 4b are fixedly connected to both sides of the main board 16. A spring 4c is connected between the sliding sleeve 4a and the upper end surface of the C-shaped frame 15, and the spring 4c is sleeved outside the sliding rod 4b. Two elastic bands 4d are connected between the main board 16 and the swing plate 17. When the product falls onto the swing plate 17, it drives the swing plate 17 and the main board 16 to fall simultaneously under the action of gravity, causing the sliding sleeve 4a to move up and down on the sliding rod 4b and compressing the spring 4c at the same time, initially buffering the fall of the product. At the same time, the swing plate 17 rotates downward on one side of the main board 16, and the product is secondarily buffered by the tension of the elastic band 4d, improving the buffering effect and preventing the product from being damaged due to direct fall.

[0030] Specifically, the output end of the weighing device 8 is electrically connected to the input end of the total controller 9, and the output end of the total controller 9 is electrically connected to the input end of the air cylinder 10. When the product passes through the weighing device 8, weight data is sent to the total controller 9. The total controller 9 then compares the weight. When they do not match, it controls the operation of the air cylinder 10 to drive the push plate 11 to move and push the product out.

[0031] With the above structure, during use, the adjustment assembly 3 drives the two guide plates 14 to deflect at an angle against the elastic force of the elastic structure, so that the ends of the two guide plates 14 are located in the middle of the surface of the conveyor belt 6. When the product is conveyed to the surface of the conveyor belt 6, it contacts the two guide plates 14 and is positioned in the middle of the conveyor belt 6. Subsequently, when passing through the weighing device 8, the weight of the product is weighed, and the data is sent to the total controller 9 for reading and comparison. When the data does not match, the air cylinder 10 is controlled to drive the push plate 11 to move, and finally the product is pushed out of the conveyor belt 6. At this time, the product falls onto the main board 16 and the swing plate 17, falls under the action of gravity, and slowly falls through the buffer assembly 4, and drives the swing plate 17 to flip downward during the fall, causing the product to drop and completing the buffering.

[0032] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
