Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a coating machine spray buffer system. Background Technology

[0002] A coating machine is a highly efficient, energy-saving, safe, and clean mechatronic device capable of applying organic film coating, water-soluble film coating, and sustained-release or controlled-release coating to tablets, pills, candies, and other pharmaceutical products. Coating machines are suitable for the pharmaceutical, chemical, and food industries.

[0003] The stability of the spray gun's liquid dispensing is a crucial factor affecting the uniformity of tablet mixing. Currently, during the spray gun dispensing process, compared to the traditional process of mixing tank-peristaltic pump-spray gun, the dispensing stability exhibits some pulsating fluctuations. These pulsating fluctuations can lead to adverse effects such as affecting the accuracy of metering and proportioning, and discontinuous dispensing. Therefore, higher requirements are needed to eliminate the pulsating phenomenon. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing a coating machine spray buffer system to solve the aforementioned problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This coating machine spray buffer system includes a support frame and several buffer components arranged on the support frame and equidistantly distributed along the length of the support frame. The buffer components buffer the spray liquid delivered by the peristaltic pump to eliminate the fluctuation of the spray liquid during flow. It includes a transmission pipe and a buffer tank. The transmission pipe has an inlet for receiving the liquid delivered by the peristaltic pump, a buffer outlet connected to the buffer tank, and a spray gun outlet for delivering the spray liquid into the spray gun. The buffer tank allows the spray liquid to enter and eliminates the spray liquid fluctuation.

[0006] Further improvements were made to the transmission tube, which has a T-shaped configuration, including a horizontal section and a vertical section located in the middle of the horizontal section. The liquid inlet and the liquid outlet of the spray gun are respectively located at the two ends of the horizontal section, and the liquid outlet for buffering is located at the upper end of the vertical section.

[0007] Further improvements include the addition of hose connectors for inserting infusion hoses on both the inlet and outlet of the spray gun. The hose connectors and the transmission pipe, as well as the buffer tank and the transmission pipe, are connected by flange structures.

[0008] Further improvements include setting the support as a plate-shaped component, which is bent to form a top plate, two side plates, and two bottom plates. The side plates are perpendicular to the top plate, and the bottom plates are perpendicular to the side plates. The top plate and side plates are connected by an assembly node that defines the final assembly position of the transmission pipe on the support.

[0009] Further improvements include setting the assembly node as a U-shaped groove that is simultaneously formed on the top plate and side plate and has a placement space. The transmission pipe is placed in the placement space and abuts against the two inner walls of the U-shaped groove formed in the placement space along the assembly direction opposite to the transmission pipe entering the placement space.

[0010] Further improvements include the installation of assembly slides on both inner walls of the support frame, with the slides located on the side and top plates respectively. A pressure plate is also installed within the placement space to prevent the transmission pipe from detaching from the space. The pressure plate has lugs at both ends that slide within the assembly slides. These lugs are secured with bolts when in contact with the bottom surface of the assembly slides. A through hole is located in the center of the pressure plate on the top plate, allowing the vertical section of the transmission pipe to pass through.

[0011] The beneficial effects of this utility model are: This invention eliminates the pulsation of the spray by guiding the undulating spray into the buffer tank, and the incoming spray can compress the air in the buffer tank. When the spray wave reaches the pipe section corresponding to the outlet of the buffer tank, the spray in the buffer tank will be released into the pipe due to pressure, thereby forming a stable flow and reducing the pulsation phenomenon. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the full cross-section of the present invention; Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings: Referring to the attached diagram: This coating machine spray buffer system includes a support 1 and several buffer components 2 disposed on the support 1 and equidistantly distributed along the length of the support 1. The buffer components 2 buffer the spray liquid delivered by the peristaltic pump to eliminate the fluctuation of the spray liquid during flow. It includes a transmission pipe 21 and a buffer tank 22. The transmission pipe 21 has an inlet 211 for receiving the liquid delivered by the peristaltic pump, a buffer outlet 212 connected to the buffer tank 22, and a spray gun outlet 213 for delivering the spray liquid into the spray gun. The buffer tank 22 allows the spray liquid to enter and eliminates the spray liquid fluctuation. The principle of this invention is that the sprayed liquid enters the transmission pipe 21 from the inlet 211. Under the action of the peristaltic pump, the sprayed liquid exhibits a wave-like motion inside the transmission pipe 21. When the sprayed liquid reaches the pipe section corresponding to the buffer outlet 212 of the transmission pipe 21, due to the pressure, the sprayed liquid will enter this pipe section and then enter the buffer tank 22 through the buffer outlet 212. The entering sprayed liquid can compress the air in the buffer tank 22, thereby eliminating the fluctuation of the sprayed liquid. When the sprayed liquid wave reaches the pipe section corresponding to the buffer outlet 212 in the pipeline, the sprayed liquid in the buffer tank 22 will be released into the pipeline due to the pressure, thereby forming a stable flow and reducing the pulsation phenomenon.

[0014] The transmission pipe 21 has a T-shaped configuration, including a horizontal section 214 and a vertical section 215 located in the middle of the horizontal section 214. The liquid inlet 211 and the spray gun outlet 213 are respectively located at both ends of the horizontal section 214, and the buffer outlet 212 is located at the upper end of the vertical section 215. This configuration makes the transmission pipe 21 a three-way pipe, which can simultaneously provide the liquid inlet 211, the buffer outlet 212, and the spray gun outlet 213. This allows the fluctuating liquid to be guided into the buffer tank 22 when the sprayed liquid flows to the middle section of the pipe.

[0015] Both the inlet 211 and the outlet 213 of the spray gun are connected to hose connectors 3 for inserting infusion hoses. The hose connectors 3 and the transmission pipe 21, as well as the buffer tank 22 and the transmission pipe 21, are connected by flange structures. In the fluid delivery system, the hose connectors 3 achieve a reliable, sealed, and detachable connection with the hose. The flange structure connection ensures coaxiality, and the two flanges can be quickly connected by clamps after being spliced ​​together. The specific assembly method is as follows: align the two flanges, place a suitable sealing gasket in the middle, wrap the two halves of the clamps around the grooves of the two flanges, tighten the bolts on the clamps, and the inner lip of the clamps will cause the flanges to embed, generating a strong axial tensile force that pulls the two flanges tightly towards each other. While the two flanges are being tightened, the gasket between them is fully compressed, forming a reliable seal and ensuring the coaxiality of the two flanges.

[0016] The support 1 is a plate-shaped component, which is bent to form a top plate 11, two side plates 12, and two bottom plates 13. The side plates 12 are perpendicular to the top plate 11, and the bottom plates 13 are perpendicular to the side plates 12. The top plate 11 and the side plates 12 are provided with assembly nodes 4 to define the final assembly position of the transmission pipe 21 on the support 1. The bottom plate 13 is used as a mounting component for connecting to other components by means of bolts. The assembly nodes 4 are used to define the final assembly position of the transmission pipe 21 on the support 1. The number of assembly nodes 4 matches the number of transmission pipes 21. At the same time, the top plate 11 and the two side plates 12 form three contact points with the transmission pipe 21, thereby ensuring the stable setting of the transmission pipe 21 within the assembly nodes 4.

[0017] Assembly node 4 is configured as a U-shaped groove formed simultaneously on top plate 11 and side plate 12, with a placement space 41. The transmission pipe 21 is placed in the placement space 41 and abuts against the two inner walls of the U-shaped groove formed in the placement space 41 along the assembly direction opposite to the transmission pipe 21 entering the placement space 41. The U-shaped configuration of top plate 11 and two side plates 12 can be adapted to the T-shaped configuration of transmission pipe 21, thereby forming three contact points. Moreover, the width of the U-shaped groove is adapted to the outer diameter of transmission pipe 21, so that abutting contact can be achieved. Abutting contact can ensure the stability of the transmission pipe 21 in the assembly node 4, prevent the transmission pipe 21 from shaking in the assembly node 4, and thus ensure the stability of liquid spraying transmission.

[0018] The placement space 41 has assembly slides 411 on both inner walls of the bracket 1, and the assembly slides 411 are respectively located on the side plate 12 and the top plate 11. A pressure plate 5 is also provided in the placement space 41 to prevent the transmission pipe 21 from leaving the placement space 41. Both ends of the pressure plate 5 have lugs 51 that slide within the assembly slides 411. The lugs 51 are fixed by bolts when in contact with the bottom surface of the assembly slides 411. A through hole 52 is provided at the center of the pressure plate 5 located on the top plate 11 for the vertical section 215 of the transmission pipe 21 to pass through. The assembly slides 411 facilitate the installation of the pressure plate 5; that is, the pressure plate 5 uses the lugs 51 to slide within the assembly slides 411. The pressure plate 5 slides to the position of the transverse section of the transmission tube 21 in the placement space 41 or moves out of the placement space 41. When the pressure plate 5 reaches the position of the transverse section of the transmission tube 21, it presses on the tube section, thereby limiting the movement of the transmission tube 21 along the assembly direction provided by the placement space 41. The pressure plate 5 located at the top plate 11 has a through hole 52 at its center position for the vertical section 215 of the transmission tube 21 to pass through. This is specifically set according to the configuration of the transmission tube 21. After the vertical section 215 passes through, the pressure plate 5 also presses on the transverse section 214. After the pressure plate 5 presses on the tube section of the transmission tube 21, the lug 51 is fixed by bolts.
