Description

Technical Field

[0001] This utility model relates to the field of drug coating equipment technology, and in particular to a uniform spray nozzle for coating liquid of Fuyankangfu tablets. Background Technology

[0002] In the production process of Fuyankangfu tablets, the coating process plays a key role in improving drug stability, appearance and taste. The spray nozzle is the core component of the coating equipment. Its main function is to spray the coating liquid evenly and stably onto the surface of the Fuyankangfu tablets so that the tablets are uniformly coated, thereby improving drug stability. The existing spray nozzles for coating liquid of Fuyankangfu tablets often become clogged during use due to impurities and viscous components in the coating liquid. Once the nozzles are clogged, they cannot be replaced quickly, leading to production stoppages and increasing production and time costs. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a uniform spray nozzle for coating liquid of Fuyankangfu tablets, which aims to improve the problem of the coating liquid spray nozzle not responding quickly after clogging.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a uniform spray nozzle for coating liquid of Fuyankangfu tablets, comprising a spray channel, a sealing element fixedly connected to the top of the spray channel, a plunger slidably connected inside the spray channel, a flow control element rotatably connected to the inner wall of the spray channel, a rotating disk fixedly connected to the top of the flow control element, two second connecting pipes fixedly connected to the surface of the spray channel, each of the two second connecting pipes being provided with a replacement component, a sealing component being provided on the left side of each of the two second connecting pipes, a liquid inlet component being provided at the top of the spray channel, and a liquid delivery component being provided on the right side of the plunger.

[0005] Through the above technical solution: the flow control component is a spherical structure with a T-shaped groove inside, which is rotatably connected to the inner wall of the spraying channel. The rotating disk fixed on its top provides a control interface for the rotation operation. By rotating the rotating disk, the flow control component can be rotated, thereby changing the communication state between the T-shaped groove inside the flow control component and the two second connecting pipes. The rotating disc is operated according to actual needs to adjust the flow direction of the coating liquid between the two second connecting pipes, ensuring that the coating liquid can be delivered to the target position. The plunger, which is slidably connected in the spraying channel, can slide back and forth in the channel. During the coating process, the plunger can pressurize the coating liquid in the channel, causing the coating liquid to move and ensuring stable delivery of the coating liquid. The sealing element fixed at the top of the spraying channel is located at the connection between the spraying channel and the flow control element. It has a ring-shaped structure and can prevent the coating liquid from leaking at the contact point between the top of the channel and the flow control element, ensuring sealing and preventing the coating liquid from overflowing and causing waste and pollution to the working environment. It also avoids the problem of unstable coating liquid flow caused by leakage.

[0006] Preferably, both replacement components include a connecting cover, both connecting covers are threadedly connected to two second connecting pipes, both connecting covers have a first connecting pipe inside, both first connecting pipes have a fixing ring fixedly connected to their surfaces, both first connecting pipes have a pressing component on their surfaces, and both first connecting pipes have a nozzle component on their left side.

[0007] The above technical solution involves connecting the connecting cover and the second connecting pipe via threads. When the nozzle assembly needs to be replaced, the connecting cover is rotated to separate it from the second connecting pipe. When installing a new assembly, the connecting cover is rotated in the opposite direction to tighten it with the threads of the second connecting pipe. The fixing ring fixedly connected to the surface of the first connecting tube serves to position and fix the spring. The connecting ring is used to connect the first connecting tube and the connecting cover. The connecting ring is slidably connected to the first connecting tube and rotatably connected to the connecting cover. When the connecting cover is connected to the second connecting tube, the connecting ring will slide on the surface of the first connecting tube and squeeze the spring. Under normal working conditions, the spring is in a compressed state, and the elastic force makes the fixing ring always apply a pressure to the second connecting tube on the first connecting tube.

[0008] Preferably, both sealing components include two sealing rings, with the two sealing rings on the right being fixedly connected to the two second connecting pipes, and the two sealing rings on the left being fixedly connected to the first connecting pipe.

[0009] The above technical solution involves fixing two sealing rings to the second connecting pipe and the first connecting pipe respectively, thereby enhancing the sealing effect and preventing the coating liquid from leaking out from the connection point. When the nozzle is working, the coating liquid flows in the pipeline at a certain pressure, and the sealing rings fit tightly against the inner wall of the pipeline, preventing the coating liquid from leaking from the connection between the second connecting pipe and the first connecting pipe, thus avoiding waste of coating liquid and pollution to the working environment.

[0010] Preferably, the liquid inlet assembly includes a liquid inlet, which is fixedly connected to the spraying channel, and a liquid storage box is threadedly connected to the top of the liquid inlet.

[0011] The above technical solution ensures that the coating liquid can flow steadily from the inlet into the spraying channel during the operation of the nozzle. At the same time, the top of the inlet is connected to the reservoir box by a thread, making it easy to disassemble and assemble the reservoir box and the inlet. When the coating solution in the reservoir is about to run out, the reservoir can be quickly unscrewed for replenishment or replacement, thereby reducing production downtime caused by interruption of coating solution supply and improving production efficiency. Since the inlet and reservoir are connected by a detachable thread, it is convenient to thoroughly clean the inlet assembly after the nozzle is used.

[0012] Preferably, the liquid delivery assembly includes a connecting block, which is fixedly connected to the plunger, and a cam is slidably connected to the surface of the connecting block.

[0013] Through the above technical solution: the connecting block is fixedly connected to the plunger, while the cam is slidably connected to the surface of the connecting block. When the cam rotates, its irregular contour will push the connecting block, thereby driving the plunger to reciprocate within the spraying channel. The cam controls the movement frequency, stroke, and speed of the plunger through a designed profile curve, thereby adjusting the pressure of the coating liquid in the spray channel to meet various coating process requirements. The plunger, under the control of the cam, makes regular reciprocating motion, which enables the coating liquid to flow smoothly in the spray channel, reduces pressure fluctuations, and avoids problems such as nozzle clogging and uneven coating thickness caused by unstable coating liquid pressure.

[0014] Preferably, the seal is ring-shaped and located at the connection between the spraying channel and the flow control element, wherein the flow control element is spherical with a T-shaped groove inside.

[0015] Through the above technical solution: the ring-shaped seal is located at the connection between the spray channel and the flow control component, and can tightly wrap around the contact area between the flow control component and the spray channel. Due to its ring-shaped structure, it can fit the irregular surface of the connection in all directions, preventing the coating liquid from leaking from this part. The flow control component is designed in a spherical shape, which allows it to rotate flexibly within the spraying channel to control the flow direction of the coating liquid. The spherical shape fits snugly against the inner wall of the channel, and no gaps are generated during rotation, ensuring the stability of the coating liquid flow. At the same time, the spherical structure facilitates rotation via a rotating disk. The T-shaped groove inside the flow control device is used to control the flow direction. When the flow control device rotates, the relative position of the T-shaped groove and the two second connecting pipes changes, thereby adjusting the coating liquid to enter different second connecting pipes, thus controlling the flow direction of the coating liquid and solving the problem of the nozzle not responding quickly after clogging.

[0016] Preferably, both of the clamping components include a connecting ring, both of the connecting rings are slidably connected to the two first connecting tubes, both of the connecting rings are rotatably connected to the two connecting covers, and both of the connecting rings are fixedly connected to the right side of the two connecting rings, and both of the springs are fixedly connected to the two fixed rings.

[0017] Through the above technical solution: one end of the spring is connected to the connecting ring and the other end is connected to the fixing ring. In the installed state, the spring is in a compressed state, thereby applying elastic force to the fixing ring. This elastic force makes the sealing ring connected to the first connecting pipe and the sealing ring connected to the second connecting pipe fit tightly together. The connecting ring is slidably connected to the first connecting tube and rotatably connected to the connecting cover. This design allows the connecting ring to slide on the surface of the first connecting tube when the connecting cover is connected to the second connecting tube.

[0018] Preferably, the nozzle assembly includes a first uniform nozzle, which is fixedly connected to a first connecting pipe on the front side, and a second uniform nozzle is disposed on the rear side of the first uniform nozzle, which is fixedly connected to the first connecting pipe on the rear side.

[0019] Through the above technical solution, the setting of the first uniform nozzle and the second uniform nozzle enables the coating liquid to be sprayed by switching nozzles after clogging. The two work together to solve the problem of the nozzle not responding quickly after clogging.

[0020] This utility model has the following beneficial effects: 1. In this utility model, a first uniform nozzle and a second uniform nozzle are provided as a whole. When one of them shows signs of blockage, the flow control element can be adjusted to change the communication state between its internal T-shaped groove and the two second connecting pipes, thereby controlling the flow direction of the coating liquid and solving the problem of the nozzle not responding quickly after blockage.

[0021] 2. In this utility model, the connecting cover is threadedly connected to the second connecting pipe, and the connecting cover is fixed to the first connecting pipe by a retaining ring. When it is necessary to disassemble the nozzle, the connecting cover is rotated so that it can be removed from the thread on the surface of the second connecting pipe, thereby solving the problem of not being able to disassemble when the nozzle is damaged.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a uniform spray nozzle for coating liquid of Fuyankangfu tablets, including a spray channel 10, a sealing element 2 fixedly connected to the top of the spray channel 10, a plunger 12 slidably connected inside the spray channel 10, a flow control element 3 rotatably connected to the inner wall of the spray channel 10, a rotating disk 1 fixedly connected to the top of the flow control element 3, two second connecting pipes 11 fixedly connected to the surface of the spray channel 10, a replacement component 5 provided on the surface of each of the two second connecting pipes 11, a sealing component 6 provided on the left side of each of the two second connecting pipes 11, a liquid inlet component 8 provided at the top of the spray channel 10, and a liquid delivery component 9 provided on the right side of the plunger 12.

[0026] Specifically, the plunger 12 can slide inside the spraying channel 10 to deliver the coating liquid. By rotating the rotating disk 1, the flow control element 3 is driven to rotate on the inner wall of the spraying channel 10. As the flow control element 3 rotates, the connection state between the two second connecting pipes 11 can be changed. Two second connecting pipes 11 are fixed on the surface of the spraying channel 10. One end of the second connecting pipe 11 is connected to the spraying channel 10 to receive the coating liquid after being adjusted by the plunger 12 and the flow control element 3. The other end is connected to the nozzle assembly 4 through the replacement component 5 to deliver the coating liquid to the nozzle assembly 4 for spraying. The replacement component 5 provided on the surface of the second connecting pipe 11 facilitates the disassembly and replacement of the nozzle assembly 4. When the nozzle assembly 4 is damaged, the nozzle assembly 4 can be quickly removed from the second connecting pipe 11 by operating the replacement component 5 for repair or replacement.

[0027] Reference Figure 1 and Figure 3 Both replacement components 5 include a connecting cover 501. Both connecting covers 501 are threadedly connected to two second connecting pipes 11. Both connecting covers 501 have a first connecting pipe 502 inside. Both first connecting pipes 502 have a fixing ring 503 fixedly connected to their surfaces. Both first connecting pipes 502 have a pressing component 7 on their surfaces. Both first connecting pipes 502 have a nozzle component 4 on their left side.

[0028] Specifically, the connecting cover 501 and the second connecting pipe 11 are connected by threads. When the nozzle assembly 4 needs to be replaced, the nozzle is removed from the second connecting pipe 11 by rotating the connecting cover 501. During installation, the connecting cover 501 is rotated in the opposite direction to connect the first connecting pipe 502 and the second connecting pipe 11 to form a passage. Each connecting cover 501 is provided with a first connecting pipe 502 inside. One end of the first connecting pipe 502 is connected to the connecting cover 501 to receive the coating liquid from the spraying channel 10 and transported through the second connecting pipe 11. The other end is connected to the nozzle assembly 4 to transport the coating liquid to the nozzle assembly 4 for coating. The fixing ring 503, which is fixedly connected to the surface of the first connecting tube 502, plays a positioning role and is the force point for the pressing assembly 7. The pressing assembly 7 is used to ensure the tightness of the connection. The nozzle assembly 4 is used to spray out the coating liquid and act on the Fuyankangfu tablet.

[0029] Reference Figure 3 Both sealing components 6 include two sealing rings 601. The two sealing rings 601 on the right side are fixedly connected to the two second connecting pipes 11, and the two sealing rings 601 on the left side are fixedly connected to the first connecting pipe 502.

[0030] Specifically, the sealing assembly 6 consists of two sealing rings 601. The two sealing rings 601 on the right side are fixed to the second connecting pipe 11 and fit tightly against the inner and outer walls of the second connecting pipe 11. Meanwhile, the two sealing rings 601 on the left side are connected to the first connecting pipe 502 and also fit tightly around the inner and outer walls of the first connecting pipe 502 to prevent the coating liquid from seeping out between the first connecting pipe 502 and the second connecting pipe 11. When the second connecting pipe 11 is connected to the first connecting pipe 502, the two sets of sealing rings 601 cooperate with each other and fit tightly together to fill any small gaps that may exist between the two connecting pipes. They can also withstand the pressure generated by the coating liquid flowing in the pipe when the nozzle is working, ensuring that the coating liquid flows completely in the preset pipe without any leakage.

[0031] Reference Figure 1 The liquid inlet assembly 8 includes a liquid inlet 801, which is fixedly connected to the spraying channel 10. A liquid storage box 802 is threadedly connected to the top of the liquid inlet 801.

[0032] Specifically, the liquid inlet 801 and the spraying channel 10 are fixedly connected to ensure that they will not separate due to vibration or other external forces during the operation of the spray head. The top of the liquid inlet 801 is connected to the liquid storage box 802 by a thread. On the one hand, when it is necessary to add or replace the coating liquid, the liquid storage box 802 can be rotated to remove it from the liquid inlet 801. On the other hand, the threaded connection can ensure the sealing of the connection, effectively preventing the coating liquid from leaking from the connection between the liquid storage box 802 and the liquid inlet 801 during the transportation process, and ensuring that the coating liquid can flow into the spraying channel 10 from the liquid storage box 802 through the liquid inlet 801 without leakage.

[0033] Reference Figure 1 and Figure 4 The liquid delivery assembly 9 includes a connecting block 901, which is fixedly connected to the plunger 12, and a cam 902 is slidably connected to the surface of the connecting block 901.

[0034] Specifically, when the cam 902 in the liquid delivery assembly 9 rotates, it drives the plunger 12 to reciprocate within the spraying channel 10 via the connecting block 901. This reciprocating motion causes pressure changes in the coating liquid within the channel, thereby controlling the flow rate and velocity of the coating liquid.

[0035] Reference Figure 1 and Figure 2 The seal 2 is ring-shaped and is located at the connection between the spray channel 10 and the flow control element 3. The flow control element 3 is a spherical shape with a T-shaped groove inside.

[0036] Specifically, the seal 2 is ring-shaped and tightly installed at the connection between the spray channel 10 and the flow control component 3. On the one hand, it can prevent the coating liquid from leaking at the contact point between the spray channel 10 and the flow control component 3. Since the coating liquid flows at a certain pressure inside the nozzle, if the seal is not good, the coating liquid will seep out, which will not only cause waste, but also contaminate other components inside the nozzle. On the other hand, the ring-shaped seal 2 can adapt to the small displacement and friction generated when the flow control element 3 rotates, maintain the sealing performance for a long time, and ensure the stability and continuity of the nozzle operation. The flow control element 3 is designed as a spherical structure with a T-shaped groove inside, which can control the flow direction of the coating liquid.

[0037] Reference Figure 3 Both clamping components 7 include connecting rings 701, both connecting rings 701 are slidably connected to the two first connecting pipes 502, both connecting rings 701 are rotatably connected to the two connecting covers 501, and springs 702 are fixedly connected to the right side of both connecting rings 701, and both springs 702 are fixedly connected to the two fixing rings 503.

[0038] Specifically, the clamping assembly 7 includes a connecting ring 701 and a spring 702. The connecting ring 701 is slidably connected to the first connecting tube 502 and rotatably connected to the connecting cover 501. One end of the spring 702 is fixed to the right side of the connecting ring 701, and the other end is fixedly connected to the fixing ring 503. Under normal operating conditions, the spring 702 is in a compressed state, and the resulting elastic force is transmitted to the first connecting pipe 502 through the fixed ring 503, causing the first connecting pipe 502 to drive the sealing ring 601 connected to it to press tightly against the other sealing ring 601, thereby ensuring that there is no leakage between the first connecting pipe 502 and the second connecting pipe 11.

[0039] Reference Figure 1 The nozzle assembly 4 includes a first uniform nozzle 401, which is fixedly connected to the first connecting pipe 502 on the front side. A second uniform nozzle 402 is provided on the rear side of the first uniform nozzle 401, which is fixedly connected to the first connecting pipe 502 on the rear side.

[0040] Specifically, the nozzle assembly 4 includes a first uniform nozzle 401 and a second uniform nozzle 402, which are fixedly connected to the corresponding first connecting pipe 502. The two nozzles work together and can immediately switch to the other nozzle after one nozzle becomes blocked.

[0041] Working principle: During normal operation, the coating liquid flows from the storage box 802 into the spraying channel 10 through the inlet 801. The cam 902 rotates and drives the plunger 12 to perform repeated liquid pushing motion. When either the first uniform nozzle 401 or the second uniform nozzle 402 shows signs of blockage, the flow control element 3 can be rotated by rotating the rotating disk 1 to change the connection state between the T-shaped groove inside the flow control element 3 and the two second connecting pipes 11, thereby solving the problem of the nozzle not responding quickly after blockage. During normal operation, the spring 702 is in a compressed state. The spring 702 drives the sealing ring 601 connected to the connecting ring 701 to press tightly against the sealing ring 601 connected to the second connecting pipe 11 through the fixing ring 503, so as to achieve a sealing state and prevent leakage. When it is necessary to disassemble the nozzle, rotate the connecting cover 501. Since the connecting cover 501 and the second connecting tube 11 are threadedly connected, rotating the connecting cover 501 allows the connecting cover 501 to be gradually removed from the threads on the surface of the second connecting tube 11. As the connecting cover 501 is rotated and removed, the elastic force of the spring 702 gradually decreases, and finally the connecting cover 501 separates from the second connecting tube 11, completing the disassembly. This solves the problem of not being able to disassemble when the nozzle is damaged.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
