Description

Technical Field

[0001] The present invention relates to the technical field of pet feeding, and more particularly to a pet medicine masking agent and a preparation device thereof. Background Art

[0002] When feeding pets, when the pets are sick, administering medicine to the pets has always been a difficult problem. Therefore, nowadays, a medicine masking agent is used to assist in administering medicine. The main function of the medicine masking agent is to improve the taste of the medicine, making it no longer bitter, so that it is more easily accepted by pets. For example, by adding components such as α, β, γ-cyclodextrin, using molecular slow-release technology to encapsulate drug molecules, masking the bitter taste and eliminating other peculiar smells, such as fishy smell, etc., while reducing the toxic and side effects of the drug and promoting absorption; The medicine masking agent usually uses sugar substitutes instead of traditional sweeteners, such as sucralose, crystalline fructose, galactooligosaccharides, and stachyose. These sugar substitutes do not participate in body metabolism, are harmless to pets, are more suitable for pets, and only need to add the medicine masking agent to the prepared medicine and stir evenly, and the operation is very simple and convenient; The current pet medicine masking agent generally improves the taste of the medicine by means of sugar substitutes, but it can only cover the taste of the medicine itself and facilitate absorption, and cannot play other roles. Moreover, when the current medicine masking agent is added to the prepared medicine for mixing, the medicine is still exposed. If the mixing is not uniform enough, the pet will still not be able to swallow the medicine; Nowadays, when preparing a pet medicine masking agent, its raw materials contain powder raw materials. Therefore, when mixing and stirring them, the powder raw materials will float in the stirring container, and the floating raw materials cannot be well mixed with the raw materials below. Moreover, when the container is opened, the powder will also float in the environment, thus damaging the working environment. And when mixing the powder raw materials with water, the powder and water cannot be well mixed, resulting in an uneven final product. Summary of the Invention

[0009] In a preferred embodiment, the metering valve is located below the sealing plate, and an elastic valve membrane is fixedly connected to the bottom end inside the drain pipe, and a conical groove is opened at the bottom end inside the water storage tank where the drain pipe is located.

[0010] In a preferred embodiment, the mixing mechanism includes a controllable output motor, an output shaft is fixedly connected to the bottom end of the output motor, an output gear is fixedly connected to the bottom end of the output shaft, a transmission gear is meshed with the side of the output gear, a synchronous gear is fixedly connected to the bottom end of the transmission gear, a rotating gear is meshed with the side of the synchronous gear away from the output gear, a rotating shaft is fixedly connected to the inside of the rotating gear, and stirring blades are fixedly connected to the side of the rotating shaft.

[0012] Technical effects and advantages of the present invention: 1.

When the reciprocating lead screw in the present invention rotates and the sealing cylinder moves downward through the lifting plate, the sealing cylinder moves downward in the connecting cylinder, and the sealing cylinder and the connecting cylinder are in a sealed state. Therefore, the pressure in the connecting cylinder and the water storage tank is increased, so that the water in the water storage tank is sprayed out through the drain pipe, and the water is located above the mixing cylinder, so that the scattered powder falls, ensuring that all the powder can be mixed and processed. 3. When the sealing cylinder moves downward in the present invention, it contacts the sealing plate and drives the sealing plate to move downward. The sealing plate seals the through hole at the bottom end of the sealing cylinder, and the sealing cylinder moves downward in a sealed state, thereby discharging the water in the water storage tank. When the sealing cylinder moves upward, the sealing plate rubs against the inside of the connecting cylinder. Therefore, the sealing cylinder moves upward prior to the sealing plate, and the sealing plate is separated from the bottom end of the sealing cylinder. At this time, the outside air can enter the connecting cylinder through the avoidance hole of the sealing cylinder, maintaining the pressure stability in the water storage tank and enabling intermittent water addition work, so that the water in the raw materials enters in batches, improving the mixing effect of water and powder.

Detailed implementation manners

[0024] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples, and a pet drug masking agent and its preparation device related to the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Refer to Figure 10 , the present invention provides a pet drug masking agent and its preparation device, which includes the following components in parts by weight: 5 - 10 parts of fish oil, 30 - 50 parts of water, 15 - 30 parts of glucose, 5 - 15 parts of chicken powder, 5 - 10 parts of chicken liver powder, 1 - 5 parts of fish meal, 2 - 10 parts of sodium carboxymethylcellulose, 0.1 - 0.3 parts of taurine, 0.1 - 0.6 parts of compound trace elements, 2 - 5 parts of compound vitamins, and 0.02 - 0.1 parts of preservative.

[0026] In the embodiments of the present application, the pet medicine masking agent of the present application has the function of masking the taste of the medicine, and the medicine masking agent of the present application itself contains influencing substances, which can supplement nutrition for pets. When in use, the medicine is made into coated granules or the tablets are crushed, and then wrapped with the medicine masking agent of the present invention for taking, so as to completely wrap the medicine and ensure the compliance of the pet taking the medicine. As Figure 10 shown, the raw material of the medicine masking agent of the present application contains water, so it can be made into different shapes to wrap different medicines.

[0027] Refer to Figure 1 and Figure 2 , a preparation device for a pet medicine masking agent, comprising support legs 1. The top of the support legs 1 is fixedly connected with a mixing cylinder 2. A sealing cover 3 is placed on the top of the mixing cylinder 2. The top of the sealing cover 3 is fixedly connected with a dust reduction and water adding mechanism 4. A mixing mechanism 5 is movably connected inside the mixing cylinder 2. The bottom end of the mixing mechanism 5 is fixedly connected with a discharge valve 8. A water inlet pipe 6 is fixedly connected to the side of the dust reduction and water adding mechanism 4. A metering valve 7 is fixedly connected to the side of the water inlet pipe 6.

[0028] In the embodiments of the present application, the powder raw material can be directly added into the mixing cylinder 2, and water can be added into the dust reduction and water adding mechanism 4 through the water inlet pipe 6. Moreover, the amount of water added through the water inlet pipe 6 can be controlled by the metering valve 7, so as to more precisely control the content of each substance in the raw material.

[0029] Refer to Figures 5 - 9, the dust-removing water-adding mechanism 4 includes a water storage tank 401 capable of storing water. A support frame 402 is fixedly connected to the top end of the water storage tank 401. A servo motor 403 is fixedly connected to the top end of the support frame 402. A reciprocating lead screw 404 is fixedly connected to the bottom end of the servo motor 403. A lifting plate 405 is threadedly connected to the side of the reciprocating lead screw 404. A sealing cylinder 407 is fixedly connected to the side of the lifting plate 405. A connecting cylinder 408 is movably connected to the side of the sealing cylinder 407. The connecting cylinder 408 communicates with the water storage tank 401. A drain pipe 413 is fixedly connected to the bottom end of the water storage tank 401. The sealing cylinder 407 seals the inside of the connecting cylinder 408. A support plate 409 is fixedly connected to the bottom end inside the sealing cylinder 407. A connecting rod 410 is movably connected to the inside of the support plate 409. A limiting plate 411 is fixedly connected to the top end of the connecting rod 410. A sealing plate 412 is fixedly connected to the bottom end of the connecting rod 410. A limiting rod 406 is movably connected to the inside of the lifting plate 405. The top end of the limiting rod 406 is fixedly connected to the bottom end of the support frame 402. When the sealing cylinder 407 drives the limiting plate 411 to move to the uppermost position, the bottom end of the lifting plate 405 does not contact the top end of the limiting plate 411. A through hole is opened at the bottom end of the sealing cylinder 407. The diameter of the through hole in the sealing cylinder 407 is larger than the diameter of the connecting rod 410. The width of the sealing plate 412 is larger than the diameter of the through hole of the sealing cylinder 407. The side of the sealing plate 412 contacts the inside of the connecting cylinder 408. The metering valve 7 is located below the sealing plate 412. And an elastic valve flap 414 is fixedly connected to the bottom end inside the drain pipe 413. A conical groove is opened at the bottom end inside the water storage tank 401 where the drain pipe 413 is located.

[0030] In the embodiment of the present application, when the sealing cylinder 407 moves downward, it will contact the sealing plate 412 and drive the sealing plate 412 to move downward synchronously. Moreover, the width of the sealing plate 412 is greater than the diameter of the through hole of the sealing cylinder 407, so that the sealing plate 412 can seal the bottom end of the sealing cylinder 407, making the sealing cylinder 407 achieve a sealing effect when moving downward. When the sealing cylinder 407 moves upward, since the side surface of the sealing plate 412 contacts the inside of the connecting cylinder 408, when the sealing cylinder 407 moves upward, the sealing plate 412 will be fixed by the inside of the connecting cylinder 408. After the sealing cylinder 407 moves upward, at this time, the sealing plate 412 is separated from the bottom end of the sealing cylinder 407, and gas will enter the sealing cylinder 407 from above and can be discharged into the connecting cylinder 408 through the through hole at the bottom end of the sealing cylinder 407, making the pressure in the connecting cylinder 408 and the water storage tank 401 stable. When the pressure in the water storage tank 401 increases, the water in the water storage tank 401 will be discharged through the drain pipe 413. When discharging, it needs to pass through the elastic valve flap 414, and at this time, the elastic valve flap 414 will be deformed to squeeze out the water. When the pressure in the water storage tank 401 is balanced, the elastic valve flaps 414 contact each other, thus sealing the bottom end of the drain pipe 413. At this time, the powder below the drain pipe 413 cannot enter the drain pipe 413 through the elastic valve flap 414, ensuring that the drain pipe 413 and the water storage tank 401 are relatively clean. Therefore, in the present application, as the sealing cylinder 407 moves up and down, liquid will be intermittently ejected downward, water is added in batches, and the mixing work is carried out multiple times, so that the raw materials in the mixing cylinder 2 are more evenly mixed after mixing.

[0031] Referring to Figure 3 And Figure 4 , the mixing mechanism 5 includes a controllable output motor 501. The bottom end of the output motor 501 is fixedly connected with an output shaft 502. The bottom end of the output shaft 502 is fixedly connected with an output gear 503. The side surface of the output gear 503 is meshed with a transmission gear 504. The bottom end of the transmission gear 504 is fixedly connected with a synchronous gear 505. The side surface of the synchronous gear 505 far from the output gear 503 is meshed with a rotating gear 506. The inside of the rotating gear 506 is fixedly connected with a rotating shaft 508. The side surface of the rotating shaft 508 is fixedly connected with stirring blades 509. The bottom end of the sealing cover 3 is fixedly connected with a sealing box 507. The rotating gear 506, the synchronous gear 505 and the output gear 503 are all located inside the sealing box 507. The drain pipes 413 in the dust reduction and water adding mechanism 4 are distributed inside the sealing cover 3, and the inside of the sealing cover 3 covered by the sealing box 507 does not contain drain pipes 413.

[0032] In the embodiment of the present application, the output shaft 502 rotates and drives the output gear 503 to rotate. When the output gear 503 rotates, it drives the transmission gear 504 to rotate at an accelerated speed. When the transmission gear 504 rotates at an accelerated speed, it drives the synchronous gear 505 to rotate synchronously and causes the rotating gear 506 to rotate at an accelerated speed again. When the rotating gear 506 rotates, it drives the rotating shaft 508 to rotate through the sealing box 507. The stirring blades 509 that rotate at an accelerated speed can achieve a better mixing effect. The sealing box 507 continues to seal the gears to prevent dust from contacting the gears, and the inside of the sealing cover 3 covered by the sealing box 507 does not contain the drain pipe 413, so that the water sprayed by the drain pipe 413 will all enter the mixing cylinder 2.

[0033] Working principle of the present invention: Put the powder raw materials into the mixing cylinder 2, seal the sealing cover 3 and the mixing cylinder 2, the water inlet pipe 6 adds water into the connecting cylinder 408, and the metering valve 7 controls the water inlet pipe 6 to add a fixed amount of water. The water entering the connecting cylinder 408 is stored in the connecting cylinder 408 and the water storage tank 401. At this time, the metering valve 7 is closed; After adding the water and the powder raw materials, the output motor 501 is started. When the output motor 501 is started, it drives the output shaft 502 to rotate. The output shaft 502 rotates and drives the output gear 503 to rotate. When the output gear 503 rotates, it drives the transmission gear 504 to rotate at an accelerated speed. When the transmission gear 504 rotates at an accelerated speed, it drives the synchronous gear 505 to rotate synchronously and causes the rotating gear 506 to rotate at an accelerated speed again. When the rotating gear 506 rotates, it drives the rotating shaft 508 to rotate through the sealing box 507, so as to mix the powder raw materials in the mixing cylinder 2; When the powder raw materials are being mixed, the servo motor 403 is started and drives the reciprocating lead screw 404 to rotate. The reciprocating lead screw 404 rotates and causes the lifting plate 405 to move downward. When the lifting plate 405 moves downward, it drives the sealing cylinder 407 to move downward. When the sealing cylinder 407 moves downward, it contacts the lower sealing plate 412 and drives the sealing plate 412 to move downward synchronously. As Figure 7 shown, at this time, the sealing plate 412 seals the through hole below the sealing cylinder 407, and the inside of the sealing cylinder 407 and the connecting cylinder 408 is in a sealed state. Therefore, when the sealing cylinder 407 moves downward, it will increase the internal pressure of the connecting cylinder 408 and the water storage tank 401 communicating with the connecting cylinder 408. Furthermore, the water in the water storage tank 401 is discharged downward through the drain pipe 413, and when the water is discharged through the drain pipe 413, it will squeeze and deform the elastic valve flap 414, and then discharge from the junction after the elastic valve flap 414 is deformed. When the water is discharged from the drain pipe 413, it is discharged from the uppermost part of the mixing cylinder 2, and the powder floating during the mixing in the mixing cylinder 2 can be washed down, achieving the effect of dust reduction, so that the raw materials in the mixing cylinder 2 are all mixed below the mixing cylinder 2 by the rotation of the rotating shaft 508; When the sealing cylinder 407 moves to the lowest position, as the water storage tank 401 rotates, the lifting plate 405 will drive the sealing cylinder 407 to move upward. When the sealing cylinder 407 moves upward, the side surface of the sealing plate 412 contacts the inside of the connecting cylinder 408. Therefore, when the sealing cylinder 407 moves and drives the support plate 409 to move, before the bottom end of the support plate 409 contacts the limiting plate 411, the position of the sealing plate 412 is fixed by the connecting cylinder 408. At this time, the sealing plate 412 is separated from the bottom end of the sealing cylinder 407, and the outside air can enter the connecting cylinder 408 through the upper part of the sealing cylinder 407 and the through hole of the sealing cylinder 407, so that the pressure in the connecting cylinder 408 is balanced. When the sealing cylinder 407 drives the support plate 409 to move upward again, the support plate 409 contacts the limiting plate 411 and drives the limiting plate 411 to move upward. When the limiting plate 411 moves upward, it drives the sealing plate 412 to move upward through the connecting rod 410. At this time, the friction between the side surface of the sealing plate 412 and the inner wall of the connecting cylinder 408 is less than the pulling force of the support plate 409 moving upward, and the sealing plate 412 will move upward and reset until the sealing cylinder 407 moves to the uppermost position and then moves downward again; When the sealing cylinder 407 moves upward, the pressure in the water storage tank 401 is balanced. Therefore, the elastic valve flap 414 will reset, thereby sealing the bottom end inside the drain pipe 413, and preventing the particles that float up again from entering the inside of the drain pipe 413. The sealing cylinder 407 moves up and down reciprocally, causing the drain pipe 413 to spray water intermittently, enabling the raw material water to enter the mixing cylinder 2 alternately, mixing the water in batches, and improving the mixing effect. As water is added, the mixed material changes from dry to wet state, and the wet raw material is discharged through the discharge valve 8 for collection.

[0034] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
