Description

Technical Field

[0001] The utility model relates to the field of medicine production equipment, in particular to a medicine powder filling tank. Background Art

[0002] During the preparation and production process of medicinal powder, the produced medicinal powder needs to be filled into different packaging bottles and then transported to various production and sales locations.

[0003] The existing filling method is to pour the produced medicine powder into the medicine powder can, and then fill the medicine powder can with the corresponding opening from the fixed specification of the discharge port.

[0004] When too much powder enters the powder tank, it will accumulate at the bottom of the tank due to the extrusion force, which will affect the discharge efficiency of the powder tank. Although the existing powder tank device uses stirring, vibration and other methods to alleviate this problem, when the amount of powder is small and no accumulation occurs, continuous stirring / vibration will lead to excessive waste of energy such as electricity.

[0005] A lot of medicine powder will be blown up during the filling process. If the blown medicine powder is not handled in time, it will not only cause waste of raw materials and increase costs, but also too much medicine powder entering the air will easily affect the factory environment and even cause dangerous consequences such as dust explosions.

DETAILED DESCRIPTION

[0022] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings as follows:

[0023] The utility model proposes a method for producing a medicine powder filling tank, referring to Figure 1-Figure 2 As shown, it mainly includes: an outer shell 1, an inner liner 2 and a discharging unit 4. The outer shell 1 and the inner liner 2 are both hollow structures. The inner liner 2 is arranged in the outer shell 1 and the outer wall of the inner liner 2 is slidably connected to the inner wall of the outer shell 1.

[0024] The top of the shell 1 is higher than the top of the liner 2. The top inner wall of the shell 1 is provided with a plurality of air suction ports 11 along the circumferential direction of the shell 1. An annular cavity (not shown in the figure) is provided inside the top of the shell 1. The plurality of air suction ports 11 are respectively connected to the annular cavity. A recovery pipe 3 is fixedly provided on the outer wall of the shell 1. One end of the recovery pipe 3 is connected to the annular cavity. An air pump is provided on the other end of the recovery pipe 3 and is connected to a recovery bin. The air pump generates suction force on the shell 1 through the recovery pipe and the air suction ports 11, and the raised medicine powder is promptly collected into the recovery bin.

[0025] On the one hand, if the medicine powder is blown up and floats in the air, it will not only pollute the working environment, but also affect safety due to the dust effect. On the other hand, the medicine powder will also cause a waste of raw materials. Therefore, the medicine powder is recovered by the recovery pipe 3 and then refilled.

[0026] A plurality of limiting grooves 13 are arranged inside the shell 1 along the circumference of the shell 1 , the outer wall of the inner liner 2 is fixedly connected to one end of an extension rod 12 , and the other end of the extension rod 12 is slidably connected to the inner wall of the limiting groove 13 , and the inner liner 2 can slide up and down driven by the extension rod 12 .

[0027] A buffer induction member 5 and a cylinder 14 are provided at the bottom of the limit groove 13. The buffer induction member 5 is provided directly below the extension rod 12 and is used to abut against the extension rod 12. The buffer induction member 5 includes an induction plate 54, an elastic rod 52, a top plate 51 and a touch cone 53. The induction plate 54 is fixedly provided on the bottom side of the limit groove 13. There are multiple elastic rods 52, and the multiple elastic rods 52 are symmetrically provided on both sides of the induction plate 54. The bottom of the elastic rod 52 is fixedly connected to the bottom side of the limit groove 13. The top plate 51 is located directly below the extension rod 12. The top plate 51 is fixedly connected to the elastic rod 52. The touch cone 53 is fixedly connected to the bottom of the top plate 51. The touch cone 53 is located directly above the induction plate 54 and is used to contact the induction plate 54. When the touch cone 53 contacts the induction plate 54, the height of the top surface of the top plate 51 is greater than or equal to the lowest height of the top surface of the piston rod of the cylinder 14.

[0028] When medicine powder accumulates at the bottom of the inner liner 2, the weight of the medicine powder will drive the inner liner 2 to be pressed downward. The extension rod 12 located directly above the top plate 51 slides downward under the drive of the inner liner 2 and generates a downward thrust on the top plate 51. The symmetrically arranged elastic rods 52 can support the top plate 51 to ensure that only when the weight generated by the accumulation of medicine powder in the inner liner 2 reaches a certain value, it is sufficient to make the top plate 51 overcome the elastic force of the elastic rods 52 and move downward until the touch cone 53 touches the sensing plate 54.

[0029] The induction plate 54 and the cylinder 14 are electrically connected to a controller (not shown in the figure) respectively. When the induction plate 54 senses the touch of the touch cone 53, it will feedback a signal to the controller. The controller controls the telescopic rod of the cylinder 14 to extend, and pushes the inner liner 2 upward with the cooperation of the elastic rod 52. At this time, the top plate 51 is away from the induction plate 54 under the action of the elastic force. The controller controls the cylinder to retract the telescopic rod due to the disconnection of the feedback signal, and the inner liner 2 falls downward until the extension rod 12 contacts the top plate 51. At this time, if there is still heavy medicine powder accumulated in the tank, the above action will be repeated to continue to dredge. If there is no medicine powder accumulated in the tank, the weight is not enough to make the touch cone 53 touch the induction plate 54 downward, so the up and down sliding dredge is stopped to save electricity. Until the medicine powder injected into the inner liner accumulates again, causing the weight to increase, and again overcomes the pressure generated by the elastic rod 52 downward, the above action will be repeated to dredge.

[0030] The number of elastic rods 52 depends on the specific weight to be transported by sliding, and is not limited in this application. The bottom of the outer shell 1 and the inner liner 2 are both provided with a discharge port, and the discharge unit 4 is arranged at the bottom of the outer shell 1. The discharge unit 4 includes a rotating rod 44 and a discharge block. There are multiple discharge blocks, and the multiple discharge blocks are fixedly connected to the rotating rod 44 through multiple connecting rods 45. The bottom of the rotating rod 44 is fixedly connected to the motor shaft of a motor (not shown in the figure).

[0031] Each discharge block is provided with an inverted truncated cone-shaped adapter opening, and the top diameter of each adapter opening is the same as the diameter of the discharge opening.

[0032] The length of the connecting rod 45 is such that each adapter port can reach the corresponding position at the bottom of the discharge port through the rotation of the rotating rod 44 and be connected to the discharge port. The top opening of the adapter port is consistent with the diameter of the discharge port to ensure that the powder can enter the adapter port without waste after being discharged from the discharge port. In order to avoid wastage of powder in this process, the adapter port should be as close to the discharge port as possible.

[0033] Each adapter has a different bottom diameter (specified by Figure 2 As shown in the figure, in this embodiment, three discharging blocks are provided. When the opening size of the filled powder bottle is adapted to the size of the discharging port, the first discharging block 41 is connected to the discharging port through the rotating rod 44, so that the discharging specification is consistent with the discharging port, which is the maximum discharging specification of the device.

[0034] When the opening size of the powder bottle is smaller than the discharge port, the second discharge block 42 is connected to the discharge port through the rotating rod 44, and the discharge size specification is reduced through the hole-shaped adapter port to make the discharge specification adapt to the corresponding powder bottle bottle opening specification.

[0035] When the opening size of the powder bottle is much smaller than the discharge port, the third discharge block 43 is connected to the discharge port through the rotating rod 44. The discharge specification is adjusted to the minimum according to the above principle to adapt the discharge specification to the corresponding powder bottle opening specification.

[0036] In the actual production process, those who implement this patented technology can adjust the number of discharge blocks and the bottom diameter size of the adapter port of each discharge block according to their own product specifications, and this application is not limited here.

[0037] The working process of the utility model is:

[0038] Before use, the produced medicine powder is injected into the inner liner of the medicine powder tank. During the filling process, once the bottom of the medicine powder tank is blocked and accumulated, the pressure of the inner liner 2 on the top plate 51 through the extension rod 12 will continue to increase, and the pressure will continuously overcome the supporting force brought by the elastic force of the elastic rod 52, so that the touch cone 53 at the bottom of the top plate 51 touches the sensing plate 54, thereby sensing the signal through the controller cylinder 14, and the controller controls the telescopic rod of the cylinder 14 to extend upward, and with the cooperation of the elastic force of the elastic rod 52, an upward thrust is generated on the extension rod 12, so that the inner liner 2 slides upward, and the medicine powder is lifted up by the rapid sliding, thereby producing a dredging effect.

[0039] When the air pump is started, the suction force generated by the air pump will give an inward suction force to the air suction port 11 through the recovery pipe 3 and the cavity. The medicine powder lifted up by the upward sliding of the inner liner 2 will be sucked into the cavity by the air suction port 11 through the suction force, and enter the recovery pipe 3 through the cavity, and finally enter the recovery bin for recovery.

[0040] At the same time, the motor is started to drive the rotating rod 44 to rotate, and the discharge block corresponding to the required adapter port is determined according to the size of the top opening of the powder bottle for loading the powder, and the discharge block is rotated to below the discharge port of the powder tank to perform the filling operation.

[0041] As for other undisclosed technologies of the present invention, such as the linear connection mode, the positioning and movement of the powder bottle, the size of the top opening of the powder tank and the filling method, as well as the relevant program writing, the prior art is mature and does not belong to the technical problems mainly solved by the present invention, so the present invention will not elaborate and limit them.

[0042] The above detailed description is a specific description of a feasible embodiment of the present invention, but the embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not deviate from the technical spirit of the present invention should be included in the patent scope of this application.
