Description

Technical Field

[0001] The invention relates to the field of drop pills, and in particular to a drop pill machine with uniform drop pill forming and a control method thereof. Background Art

[0002] The pill machine is a device used in the preparation process of spherical food, pharmaceuticals, metals, etc. Its working principle is to place the heated, dissolved, emulsified or diluted pills in the storage tank, and the pills in the storage tank are pushed through the nozzle to form a uniform jet under the action of the micro gear pump. The jet liquid breaks into uniform droplets under the action of gravity, and the droplets condense and shrink to obtain pills of a specific particle size.

[0003] In order to facilitate the pills to fall off, the prior art generally sets an oscillator on the pill dropper, and the oscillator oscillates in the vertical direction to throw the pills off the dropper. However, the pills are generally viscous liquids. After they are separated from the nozzle and contacted with the outside air, the temperature decreases, causing the viscosity to increase. Figure 1 The oscillation process of the oscillator will first increase the contact area between the nozzle and the pills, and then pull the distance to make them fall off. At this time, a part of the pills will adhere to the surface of the nozzle and gradually solidify. The solidified pills will get stuck or even block the nozzle, thereby increasing the contact area between the nozzle and the pills, making the nozzle have a higher surface tension on the pills, making it difficult for the pills to leave the nozzle, and ultimately resulting in a larger particle size of the prepared pills.

[0004] In view of the above problems existing in the prior art, the purpose of the present invention is to design a pill machine with uniform pill forming and a control method thereof. Summary of the invention

[0011] The control system is used to control the rotation speed of the rotating motor when the pills are output from the nozzle hole, so that the pills are separated from the nozzle hole by centrifugal force, and to control the flow rate of the air pump to push the pills downward after they have separated from the nozzle hole.

[0012] Furthermore, it comprises a discharge pipe and a filter tank, wherein the discharge pipe is arranged at the bottom end of the storage tank, and the filter tank is arranged at the discharge end of the discharge pipe.

[0014] Furthermore, a waste collection frame is provided at the top of the cooling tank, and an avoidance hole is provided in the middle of the waste collection frame. When the dripper rotates at a high speed, the attachments on the dripper are thrown into the waste collection frame. When the dripper rotates at a low speed, the avoidance hole allows the droplets to pass through.

[0015] Furthermore, the cooling tank is provided with a driving member at the top end thereof for driving the waste collecting frame to move up and down.

[0016] Furthermore, the bottom surface of the waste collection frame gradually rises from the outer circle to the inner circle.

[0017] Furthermore, the air injection hole faces the center of the bottom surface of the cooling tank.

[0018] A control method for a pill machine with uniform pill forming is further provided, based on the pill machine with uniform pill forming, comprising the following steps:

[0019] When the spray hole outputs the pills, the rotating motor is controlled to rotate at a low speed so that the pills are separated from the spray hole by centrifugal force, and the air pump is controlled to work so as to push the pills separated from the spray hole downward.

[0020] Furthermore, before the spray hole outputs the pills, the waste collection frame is driven to move upwards by the driving member;

[0021] After the spray hole outputs the pills for a period of time, the output of the pills is stopped, the waste collection frame is driven downward by the driving member, and the rotating motor is controlled to rotate at a high speed to throw the attachments on the dripper into the waste collection frame.

[0022] Furthermore, when the nozzle outputs the pills, the image of the pills is captured and the diameter of the pills is analyzed, and the control system is used to control the rotation speed of the rotating motor and the flow rate of the air pump according to the diameter.

[0023] Therefore, the present invention provides the following effects and / or advantages:

[0024] The present application changes the mode of outputting pills in the prior art by an oscillating mode, and optimizes it to output pills by rotating the dripper, so that the pills have centrifugal force and thus separate from the dripper, and through the cooperation of the air jet holes, the pills after separation from the dripper have a faster descending speed, preventing them from contacting the inner wall of the cooling tank.

[0035] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0036] refer to Figure 2-3 , a pill making machine for uniformly forming pills, comprising:

[0037] Storage tank 1, used for storing pills;

[0038] A drip irrigation system 2 is connected to the storage tank 1. The drip irrigation system includes a dripper 201 and a rotating motor 202. A plurality of spray holes are arranged below the dripper 201. The dripper 201 can be rotatably arranged. The rotating motor 202 drives the dripper to rotate.

[0039] In this embodiment, the working process of the pill machine is as follows: the storage tank 1 heats and insulates the pills to keep them in liquid state, and then the pills are output from the drip irrigation system by gravity or a pump body to form droplets that fall into the cooling tank 3, which stores a coolant, thereby solidifying the pills that have been softened after being heated in the storage tank 1 in advance to form a pill-shaped solid. The specific working principle and structure of the pill machine are directly adopted from the prior art and will not be elaborated here.

[0040] In this embodiment, the technical solution of using an oscillator to separate the viscous pill from the spray hole in the traditional technology is changed, and the dripper 201 is rotatable to generate centrifugal force on the outputted pill, and the centrifugal force on the pill is used to separate the dripper 201, so that the process of the pill separating from the spray hole is continuous and uniform. At the same time, since the dripper 201 does not oscillate up and down, the maximum contact area between the oscillating dripper 201 and the pill is smaller than the maximum contact area between the rotating dripper 201 and the pill provided in this embodiment, thereby reducing the adsorption force of the dripper 201 on the pill.

[0041] A cooling tank 3 is arranged below the dripper 201. An air inlet 301 and an air outlet 302 are arranged at an upper portion of the cooling tank 3. The air inlet 301 and the air outlet 302 are arranged at a vertical interval. An air inlet ring 303 is arranged on the inner wall of the cooling tank 3 at a position corresponding to the air inlet 301. The air inlet ring 303 is connected to the air inlet 301. The air inlet ring 303 is provided with a plurality of jet holes 304 at its bottom. The jet direction of the jet hole 304 is toward the bottom of the cooling tank 3. The air inlet 301 is connected to a corresponding air pump.

[0042] The control system is used to control the rotation speed of the rotating motor 202 when the droplets are output from the spray hole, so that the droplets are separated from the spray hole by centrifugal force, and to control the flow rate of the air pump to push the droplets that have separated from the spray hole downward.

[0043] In this embodiment, the dripper 201 is rotatable, so when the pills are output, in addition to moving downward, the centrifugal force carries the pills to move along the radial direction of the cooling tank 3. In order to prevent the pills from contacting the side wall of the cooling tank 3 and thus clinging to the side wall and unable to fall into the cooling tank 3, or from contacting the side wall of the cooling tank 3 and thus deforming, making the shape of the prepared pills irregular, the structure of the air jet hole 304 is added in this embodiment. The air jet hole 304 discharges air toward the bottom of the cooling tank 3, which can accelerate the falling speed of the pills on the one hand, and on the other hand, the thrust generated by the air flow of the discharged air can push the pills toward the axis of the cooling tank 3, reduce the movement speed of the pills in the circumferential direction of the cooling tank 3, and finally make the pills fall smoothly into the cooling tank 3 for cooling and solidification.

[0044] Furthermore, it comprises a discharge pipe 4 and a filter tank 5 , wherein the discharge pipe 4 is arranged at the bottom end of the storage tank 5 , and the filter tank 5 is arranged at the discharge end of the discharge pipe 4 .

[0045] Through this structure, the pellets that have solidified after cooling can be output from the discharge pipe 4 to the filter tank 5 for filtering, and the coolant at the bottom of the filter tank 5 can be returned to the cooling tank 3 .

[0046] Furthermore, the dripper 201 is a cylindrical hollow structure, the top of the dripper 201 is connected to the corresponding pipe through a sealed bearing, the side wall of the dripper 201 is provided with a circle of racks, the rotating motor 202 drives a gear, and the gear is meshed with the rack.

[0047] Furthermore, a waste collection frame 6 is provided at the top of the cooling tank 3, and an avoidance hole is provided in the middle of the waste collection frame 6. When the dripper 201 rotates at a high speed, the attachments on the dripper 201 are thrown into the waste collection frame 6. When the dripper 201 rotates at a low speed, the avoidance hole allows the droplets to pass through.

[0048] Furthermore, the cooling tank 3 is provided with a driving member 601 at its top end for driving the waste collection frame 6 to move up and down. The driving member 601 may be a cylinder, an electric cylinder, or the like.

[0049] Furthermore, the bottom surface of the waste collecting frame 6 gradually rises from the outer circle to the inner circle.

[0050] In this embodiment, the waste collection frame 6 is moved upward to expose the dripper 201 below the avoidance hole, so that the droplets output by the dripper 201 can fall smoothly into the cooling trough 3. The waste collection frame 6 is moved downward to block the dripper 201 above the avoidance hole. At this time, the residue thrown out by the high-speed rotation of the dripper 201 falls into the waste collection frame 6, and will not fall into the cooling trough 3 and mix with the qualified droplets.

[0051] Furthermore, the air injection hole faces the center of the bottom surface of the cooling tank 3 .

[0052] The air jet hole is directed toward the center of the bottom surface of the cooling tank 3 so as to blow the pills in the radial direction of the cooling tank 3 , thereby reducing the moving speed of the pills in the radial direction of the cooling tank 3 and further preventing the pills from contacting the inner wall of the cooling tank 3 .

[0053] A control method for a pill machine with uniform pill forming is further provided, based on the pill machine with uniform pill forming, comprising the following steps:

[0054] When the spray hole outputs the pills, the rotating motor 201 is controlled to rotate at a low speed so that the pills are separated from the spray hole by centrifugal force, and the air pump is controlled to work so as to push the pills separated from the spray hole downward.

[0055] In this embodiment, by controlling the rotating motor 201 to rotate at a low speed, a certain centrifugal force is applied to the pills, replacing the up and down oscillation working mode of the oscillator in the prior art, so that the pills are separated from the dripper 201 and pushed by the air jet hole 304 to fall into the cooling tank 3 at a faster speed.

[0056] Further, the following steps are included:

[0057] Before the spray hole outputs the droplets, the waste collection frame 6 is driven to move upward by the driving member 601; at this time, the dripper 201 can pass through or be located above the waste collection frame 6, so that the droplets will not be blocked by the waste collection frame 6 during the output process.

[0058] After the spray hole outputs the pills for a period of time, the output of the pills is stopped, the waste collection frame 6 is driven downward by the driving member 601, and the rotating motor 202 is controlled to rotate at a high speed to throw the attached materials on the dripper into the waste collection frame 6. At this time, the dripper 201 can be made higher than the waste collection frame 6, so that the condensed waste is received by the waste collection frame 6 during the process of being thrown out.

[0059] Furthermore, when the nozzle outputs the pills, the image of the pills is captured and the diameter of the pills is analyzed, and the control system is used to control the rotation speed of the rotating motor and the flow rate of the air pump according to the diameter.

[0060] In this embodiment, the image of the pill is captured as follows: Figure 4 As shown, for ease of observation, only one spray hole is provided so as to form an array of pellets distributed spirally downward in the cooling tank.

[0061] The following steps can be used to analyze the diameter of the pills:

[0062] Performing shape analysis on the image of the pills to extract the contour of the image of the pills;

[0063] The contour is subjected to circular recognition, and the diameter of the dropped pill is output.

[0064] The pills are in the process of dropping, and they are like circles. Figure 4 The shape analysis algorithm can use existing algorithms such as the Canny algorithm to obtain the following Figure 5 The process of circular recognition of the outline can use the Hough circle detection algorithm, which can obtain the corresponding fitting approximate circle from the image, and can calculate and output the corresponding center, radius and other data, and obtain the following Figure 6 Results shown.

[0065] Since the pills will gradually settle in the cooling tank 3, resulting in a high concentration at the bottom of the cooling tank 3 and a low concentration at the top, during the process of the dropper 201 outputting the pills, the high-concentration pills have a higher viscosity and are more easily adsorbed at the nozzle hole, making it difficult to detach, and the final result is that the volume of the dripping pills is larger. If the entire output process of the pills is controlled at the same speed of the dropper 201, the volume of the prepared pills will gradually decrease.

[0066] Therefore, in this embodiment, the rotation speed of the dripper 201 is adjusted by the diameter of the pills. When the diameter of the pills becomes smaller, the rotation speed of the dripper 201 is reduced, and the flow rate of the air pump is reduced at the same time, so that the centrifugal force on the pills becomes smaller, and more pills are gathered at the dripper 201 and then leave the dripper, thereby ensuring that the particle size of the desired pills remains at the same level.
