Description

Technical Field

[0001] This utility model relates to the field of bagging machine technology, and in particular to a bagging machine for quantitative feeding of salicylates. Background Technology

[0002] Salicylic acid nitrile, also known as o-hydroxybenzonitrile, is a chemical substance, appearing as a grayish-white powder with a highly pungent odor. It is water-soluble but unstable to strong alkalis and oxidizing agents. Salicylic acid nitrile has a wide range of applications. After production, it needs to be bagged for storage and transportation. However, current bagging methods involve placing the bag on a weighing device, then discharging the nitrile from the hopper into the bag. Once the weighing device reaches the specified weight, the hopper is closed, the bag is transferred, and the process is repeated. However, this method requires stopping the machine after each bag is filled and transferring it before the next bag can be packed. This cumbersome process reduces efficiency and results in slight variations in the weight of the nitrile in each bag. Utility Model Content

[0003] This utility model discloses a bagging machine for quantitative feeding of salicylate, which solves the problems of cumbersome operation, reduced packaging efficiency, and certain deviations in the weight of salicylate inside the packaging bag caused by displaying the weight of salicylate inside the packaging bag through a weighing device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A bagging machine for quantitative feeding of salicylates includes a base plate, a top plate above the base plate, a hopper fixed on the top plate, and a support rod fixed between the top plate and the base plate. Below the top plate is a circular plate in contact with the bottom of the hopper's discharge end. The bottom of the circular plate is connected to a set of vertical cylinders arranged in a circular array. The discharge end of the hopper corresponds to the top of one of the vertical cylinders. A motor for driving the circular plate to rotate is provided on the top plate. Below the circular plate is a sealing plate in contact with the bottom of the vertical cylinder. The sealing plate has a discharge hole located on one side of the hopper and corresponding to another vertical cylinder. A column is fixed between the sealing plate and the base plate.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After the produced salicylic acid nitrile is transported to the hopper through an external conveying pipe, the nitrile in the hopper is discharged through the discharge end of the hopper into the vertical cylinder corresponding to the hopper. When the vertical cylinder is full of salicylic acid nitrile, the motor is started to drive the circular plate to rotate. After the circular plate drives a set of vertical cylinders to rotate, one vertical cylinder full of salicylic acid nitrile moves directly above the discharge hole, while the other vertical cylinder moves directly below the hopper. After the worker places the external packaging bag directly below the discharge hole, the salicylic acid nitrile in the vertical cylinder full of salicylic acid nitrile falls downwards into the packaging bag through the discharge hole, completing the quantitative packaging of salicylic acid nitrile. When the salicylic acid nitrile in the vertical cylinder full of salicylic acid nitrile is discharged and packaged again, the salicylic acid nitrile in the hopper can be continuously discharged to... The vertical cylinder located directly below the hopper is used to quantitatively load salicylic acid nitrile. This process is repeated to continuously and quantitatively package the salicylic acid nitrile. When the circular plate rotates the vertical cylinder, the top of the plate seals the discharge end of the hopper, preventing further discharge of the salicylic acid nitrile. A sealing plate also seals the salicylic acid nitrile inside the vertical cylinder. This invention effectively packages salicylic acid nitrile quantitatively, ensuring that the weight of the salicylic acid nitrile in each bag meets the standard, avoiding significant errors in weight distribution. Furthermore, during quantitative packaging, there is no need for prolonged stops to transfer and replace packaging bags, thus improving packaging efficiency. Attached Figure Description

Detailed Implementation

[0010] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0011] like Figure 1As shown, this utility model provides a bagging machine for quantitative feeding of salicylates, including a base plate 1, a top plate 2 above the base plate 1, a hopper 3 fixed on the top plate 2, and a support rod 21 fixed between the top plate 2 and the base plate 1; a circular plate 4 below the top plate 2 is in contact with the bottom of the discharge end of the hopper 3, and a set of vertical cylinders 41 arranged in a ring array are connected to the bottom of the circular plate 4, the discharge end of the hopper 3 corresponds to the top of one of the vertical cylinders 41, and a motor 22 for driving the circular plate 4 to rotate is provided on the top plate 2; a sealing plate 5 below the circular plate 4 is in contact with the bottom end of the vertical cylinder 41, and a discharge hole 51 located on one side of the hopper 3 and corresponding to another vertical cylinder 41 is opened on the sealing plate 5, and a column 53 is fixed between the sealing plate 5 and the base plate 1.

[0012] like Figure 1 As shown, a hollow shell 6 is slidably connected to the side of the vertical cylinder 41 away from the axis of the circular plate 4. A U-shaped connecting frame 61 is fixed on the vertical cylinder 41. The portion of the hollow shell 6 outside the vertical cylinder 41 is located inside the connecting frame 61. A screw 62 is threaded onto the connecting frame 61, and one end of the screw 62 is rotatably connected to the portion of the hollow shell 6 outside the vertical cylinder 41. Depending on the loading capacity of different packaging bags, rotating the screw 62 moves the hollow shell 6 towards the outside of the vertical cylinder 41, adjusting the storage space inside the vertical cylinder 41 so that more salicylates can be loaded inside the vertical cylinder 41 to meet the loading capacity of different packaging bags.

[0013] like Figure 1 As shown, a fixing beam 63 is fixed inside the vertical cylinder 41. The bottom surface of the fixing beam 63 is slidably connected to the top surface of the hollow shell 6, and the top surface of the fixing beam 63 is arc-shaped. A scale 7 is fixed on the vertical cylinder 41 above the hollow shell 6. The fixing beam 63 effectively prevents salicylic acid from accumulating on the top of the hollow shell 6. The scale 7 allows workers to know the distance the hollow shell 6 has moved outside the vertical cylinder 41, so as to calculate how much weight of salicylic acid can be loaded inside the vertical cylinder 41.

[0014] like Figure 1 As shown, a fixing rod 23 is fixed on the top plate 2, and the bottom end of the fixing rod 23 is fixed to the main body of the motor 22; a rubber ring 42 is fitted on the vertical cylinder 41 and is fixedly connected to it, with its bottom contacting the top of the sealing plate 5. After starting the motor 22, the rotating shaft of the motor 22 can drive the circular plate 4 to rotate; the rubber ring 42 can increase the tightness of the fit between the bottom of the vertical cylinder 41 and the sealing plate 5, so as to prevent the salicylic acid inside the vertical cylinder 41 from spilling onto the sealing plate 5 when the vertical cylinder 41 moves; a rubber ring 42 can also be set at the discharge end of the hopper 3.

[0015] like Figure 1As shown, a funnel 52 covering the discharge hole 51 is fixed to the bottom of the sealing plate 5. The funnel 52 allows the salicylic acid that passes through the discharge hole 51 to be better collected into the outer packaging bag, and can accommodate different packaging bag diameters.

[0016] like Figure 1 As shown, two symmetrical vertical plates 8 are fixed to the bottom of the sealing plate 5. Electric telescopic rods 9 are fixed to the opposite sides of each vertical plate 8. Pressure blocks 91 are fixed to the telescopic ends of the electric telescopic rods 9, and the funnel 52 is located between the two pressure blocks 91. After the packaging bag covers the funnel 52, activating the two electric telescopic rods 9 causes the two pressure blocks 91 to move closer together, thus pressing the packaging bag against the funnel 52. This eliminates the need for workers to hold the bag opening, reducing their workload.

[0017] In use, the produced salicylic acid nitrile is transported to hopper 3 through an external conveying pipe. The salicylic acid nitrile in hopper 3 then enters a vertical cylinder 41 corresponding to hopper 3. When the vertical cylinder 41 is full, motor 22 is activated to drive the circular plate 4 to rotate, causing the vertical cylinder 41 containing the salicylic acid nitrile to move towards the discharge hole 51 (the circular plate 4 rotates counterclockwise). This vertical cylinder 41 then aligns with the discharge hole 51, while another vertical cylinder 41 is located directly below hopper 3. The salicylic acid nitrile in the vertical cylinder 41 is then discharged downwards through the discharge hole 51. By placing the outer packaging bag below the discharge hole 51, the salicylic acid acrylonitrile can be quantitatively packaged. At the same time, the salicylic acid acrylonitrile in the hopper 3 enters the controlled vertical cylinder 41 for quantitative loading. By following the above operation, the quantitative packaging of salicylic acid acrylonitrile can be continuously completed. When the circular plate 4 rotates, the bottom of the discharge end of the hopper 3 contacts the top of the circular plate 4, which will not cause the salicylic acid acrylonitrile in the hopper 3 to spill onto the circular plate 4. Similarly, when the circular plate 4 drives the vertical cylinder 41 to rotate, the bottom of the vertical cylinder 41 contacts the top of the sealing plate 5, which will also prevent the salicylic acid acrylonitrile from spilling.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
