Description

Technical Field

[0001] The present invention relates to the technical field of material spraying, and specifically to a spraying device for the production of medium-borosilicate pharmaceutical glass bottles. Background Art

[0002] In the current pharmaceutical packaging field, as an important packaging container for drugs, the quality and performance of pharmaceutical glass bottles are directly related to the safety, stability, and effectiveness of drugs. Medium-borosilicate pharmaceutical glass bottles have become the top choice among pharmaceutical glass bottles due to their many excellent properties such as low expansion coefficient, high chemical stability, good heat resistance, and freeze resistance. They are widely used in the packaging of various drugs, especially those with high requirements for drug quality, long-term storage, or special storage conditions.

[0003] During the production of medium-borosilicate pharmaceutical glass bottles, in order to ensure good sealing and barrier properties and meet the special requirements of drug packaging, a specific coating is usually evenly sprayed on the outer wall of the glass bottle. This coating can not only provide additional protection against external factors affecting the drugs but also further optimize the performance of the glass bottle.

[0004] In the prior art, when using a spraying device for the production of medium-borosilicate pharmaceutical glass bottles, it is often difficult to achieve uniform coating distribution during the coating spraying process. Especially for the arc-shaped concave and convex parts, since the nozzles are directly set parallel to the bottle body, it may lead to excessive coating during the spraying process, resulting in too high a coincidence rate. This not only wastes coating resources and increases production costs but also may affect the quality and thickness uniformity of the coating. At the same time, when clamping and fixing the glass bottle, the traditional clamping method on the outer wall of the bottle mouth easily exposes the clamping jaws directly to the coating environment. During continuous spraying, it will cause the clamping scratches to be covered with a thick layer of coating, resulting in the need for cleaning or replacement of the clamping jaws. Summary of the Invention

[0005] To address the above technical problems, the present invention proposes the following technical solution: A spraying device for the production of medium-borosilicate pharmaceutical glass bottles, including a housing, a glass bottle, and a conveying guide rail. A sliding frame for support is slidably installed inside the housing. A sliding rack is slidably installed on the sliding frame. An intermediate pipe is fixedly installed on the sliding rack. One end of the intermediate pipe is provided with a flange. A shunt pipe is connected to the end of the intermediate pipe provided with the flange. Multiple rubber rings are provided at the connection between the shunt pipe and the intermediate pipe to seal and prevent coating leakage. The shunt pipe is arranged according to the shape of the outer surface of the glass bottle. Multiple atomizing nozzles are provided on the side of the shunt pipe close to the vertical lead screw to atomize the coating.

[0006] Furthermore, a lifting belt is fixedly installed inside the conveying guide rail. The lifting belt is arranged at the bottom of the conveying guide rail, and extrusion bumps are arranged on the lifting belt. A rubber belt is slidably installed on the conveying guide rail. The rubber belt is made of flexible rubber material. The rubber belts are symmetrically arranged on the lifting belt, and a clamping assembly for clamping glass bottles is rotatably installed between the rubber belts.

[0007] Furthermore, the clamping assembly includes a rotating ring and inner clamping claws. The rotating ring is slidably connected to the rubber belt and is arranged between the rubber belts. A plurality of inner clamping claws for clamping glass bottles are slidably installed inside the rotating ring. A protective rubber is arranged on the surface of the inner clamping claws in contact with the glass bottles. One end of the rotating ring is in contact with the glass bottle, and a protruding protective ring is arranged at the end of the rotating ring in contact with the glass bottle. The protruding protective ring is used to protect the bottle mouth of the glass bottle from being contaminated or contacted by the coating, and the protruding protective ring does not contact the glass bottle.

[0008] Furthermore, a telescopic rod is fixedly installed on the rotating ring. The moving end of the telescopic rod is rotatably installed with a sliding block. The sliding block is slidably connected to the lifting belt. A compression spring is fixedly installed on the telescopic rod, and the other end of the compression spring is fixedly installed with a compression frustum. An inclined surface is arranged on the compression frustum, and the inclined surface on the compression frustum contacts the inner clamping claws.

[0009] Furthermore, a support plate is fixedly installed inside the housing. A rotating frame is rotatably installed on the support plate. A rotating torsion spring is fixedly installed on the rotating frame, and the other end of the rotating torsion spring is fixedly installed on the support plate. A driving wheel is rotatably installed at the end of the rotating frame away from the rotating torsion spring. The driving wheel contacts the outer wall of the rotating ring, and a main motor is fixedly installed on the housing.

[0010] Furthermore, a belt is arranged on the output shaft of the main motor, and the other end of the belt is arranged on the driving wheel. The axis of the output shaft of the main motor is aligned with the axis of the connecting shaft between the rotating frame and the support plate. When the main motor drives the driving wheel to rotate through the belt, the driving wheel can drive the rotating ring to rotate on the rubber belt.

[0011] Furthermore, a fan is arranged inside the housing to drive the airflow. An electric heating wire is fixedly installed inside the housing to heat the airflow. A diversion box is arranged on one side inside the housing to guide the flow direction of the heated airflow. A purifier is fixedly installed on the outer wall of the housing. The purifier is used to purify the volatile substances of the spraying material in the air in the housing.

[0012] The beneficial effects of the present invention compared with the prior art are as follows: (1) By providing a shunt pipe with a shape similar to that of the glass bottle body, and evenly arranging a plurality of atomizing nozzles on the shunt pipe to atomize the paint, the paint can be evenly sprayed onto the outer wall of the glass bottle, so as to achieve the purpose of paint spraying, thereby reducing the overlapping rate of paint spraying; (2) By clamping the inside of the purifier bottle mouth with the inner clamping jaws, it can not only prevent the inner clamping jaws from being affected by the paint during operation and thus reduce the service life, but also avoid the non-sprayable positions on the clamping parts of the glass bottle.

Detailed implementation manners

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] As Figures 1 to 4 shown, a spraying device for the production of medium-borosilicate pharmaceutical glass bottles includes an outer shell 101 and a delivery guide rail 201. The outer shell 101 is fixedly connected to the delivery guide rail 201. The outer shell 101 is arranged on the path of the delivery guide rail 201. The delivery guide rail 201 is an overall recyclable delivery device. A numerical control bottle clamping machine is also arranged on the delivery guide rail 201 for loading or unloading. A lifting belt 202 is fixedly installed inside the delivery guide rail 201. The lifting belt 202 is arranged at the bottom of the delivery guide rail 201. Extrusion bumps are arranged on the lifting belt 202. The extrusion bumps are arranged in the section where the glass bottle 106 needs to be clamped, generally between two numerical control bottle clamping machines for loading and unloading, so as to drive the device to clamp the glass bottle 106. Belt rollers are rotatably installed on both sides of the delivery guide rail 201. A rubber belt 203 is slidably installed on the delivery guide rail 201. The rubber belt 203 is arranged on the belt rollers. The rubber belt 203 is driven by an external electric roller. The rubber belt 203 is made of flexible rubber material. The rubber belts 203 are symmetrically arranged on the lifting belt 202. A clamping assembly is rotatably installed between the rubber belts 203.

[0025] The clamping assembly includes a rotating ring 204 and inner clamping jaws 205. The rotating ring 204 is slidably connected to the rubber belt 203. The rotating ring 204 is disposed between the rubber belts 203. A plurality of inner clamping jaws 205 are slidably installed in the rotating ring 204 for clamping the glass bottle 106. A protective rubber is provided on the surface of the inner clamping jaw 205 in contact with the glass bottle 106. One end of the rotating ring 204 is in contact with the glass bottle 106. A protruding protective ring is provided at the end of the rotating ring 204 in contact with the glass bottle 106. The protruding protective ring is used to protect the mouth of the glass bottle 106 from being contaminated or contacted by the paint. The protruding protective ring does not contact the glass bottle 106. A clamping jaw spring 206 is fixedly installed on the inner clamping jaw 205. The other end of the clamping jaw spring 206 is installed on the inner wall of the rotating ring 204. After the inner clamping jaw 205 slides on the rotating ring 204, the clamping jaw spring 206 is used to reset the inner clamping jaw 205. A telescopic rod 207 is fixedly installed on the rotating ring 204. A sliding block 210 is rotatably installed at the mobile end of the telescopic rod 207. The sliding block 210 is slidably connected to the lifting belt 202. A compression spring 209 is fixedly installed on the telescopic rod 207. The other end of the compression spring 209 is fixedly installed with a compression frustum 208. An inclined surface is provided on the compression frustum 208. The inclined surface on the compression frustum 208 contacts the inner clamping jaw 205. When the sliding block 210 moves and slides to the compression bump on the lifting belt 202, it will cause the inner clamping jaw 205 to move away from the axis of the rotating ring 204. In this way, the inner clamping jaw 205 can be brought into contact with the inner wall of the glass bottle 106, and then the inner clamping jaw 205 can be expanded inside the glass bottle 106, so as to achieve the purpose of clamping the glass bottle 106. When the sliding block 210 leaves the compression bump, the compression frustum 208 will move away from the inner clamping jaw 205. In this way, the inner clamping jaw 205 is pushed back to the initial position by the clamping jaw spring 206, so as to release the clamping of the glass bottle 106, so that the numerical control bottle clamping machine can remove the glass bottle 106 from the rubber belt 203 of the present invention.

[0026] A sliding frame 302 for support is slidably installed inside the outer shell 101. A transverse lead screw 301 is rotatably installed inside the outer shell 101. The transverse lead screw 301 is threadedly connected to the outer shell 101 and the sliding frame 302. Rotation of the transverse lead screw 301 can drive the sliding frame 302 to slide inside the outer shell 101. A vertical lead screw 306 is rotatably installed on the sliding frame 302. A sliding bracket 305 is slidably installed on the sliding frame 302. The sliding bracket 305 is threadedly connected to the vertical lead screw 306. The purpose of both the transverse lead screw 301 and the vertical lead screw 306 is to change the position of the sliding bracket 305 inside the outer shell 101, facilitating adjustment when spraying different products. A middle pipe 307 is fixedly installed on the sliding bracket 305. One end of the middle pipe 307 is provided with a flange. A shunt pipe 303 is connected to the end of the middle pipe 307 provided with the flange. The shunt pipe 303 and the middle pipe 307 are connected and fastened by bolts. A plurality of rubber rings are provided at the connection between the shunt pipe 303 and the middle pipe 307 for sealing to prevent paint leakage. The shunt pipe 303 is arranged in accordance with the outer surface shape of the glass bottle 106. A plurality of atomizing nozzles 304 are provided on one side of the shunt pipe 303 close to the vertical lead screw 306 for atomizing the paint liquid.

[0027] A paint pump 102 is fixedly installed on the outer wall of the outer shell 101. The paint pump 102 is connected to the middle pipe 307 through a rubber expansion pipe. A feed pipe 103 is fixedly installed at the inlet of the paint pump 102. The other end of the feed pipe 103 is arranged at the bottom of the storage tank 104. A filling valve is provided on the storage tank 104.

[0028] A fan 407 is provided inside the outer shell 101 to drive the flow of air. An electric heating wire 408 is fixedly installed inside the outer shell 101 to heat the air flow. A diversion box 409 is provided inside one side of the outer shell 101 to guide the flow direction of the heated air flow. A purifier 105 is fixedly installed on the outer wall of the outer shell 101. The purifier 105 is used to purify the volatile substances of the spraying materials in the air in the outer shell 101. The air inlet of the purifier 105 is fixedly connected to the upper part of the diversion box 409. The air outlet of the purifier 105 is arranged at one end away from the outer shell 101. In addition, the air outlet of the purifier 105 can also be connected to the purifier in the factory building. When the glass bottle 106 is between the electric heating wire 408 and the diversion box 409, the middle pipe 307 will drive the air flow towards the diversion box 409, and the electric heating wire 408 will heat the air flow when the air flow passes through. The paint on the outer wall of the glass bottle 106 is heated and cured by the air flow, and the hot air flow is simply purified and flows out through the purifier 105 after entering the diversion box 409.

[0029] A support plate 405 is fixedly installed inside the outer shell 101. A rotating frame 403 is rotatably installed on the support plate 405. A rotating torsion spring 404 is fixedly installed on the rotating frame 403, and the other end of the rotating torsion spring 404 is fixedly installed on the support plate 405. A driving wheel 406 is rotatably installed at one end of the rotating frame 403 away from the rotating torsion spring 404. The driving wheel 406 is in contact with the outer wall of the rotating ring 204. A main motor 401 is fixedly installed on the outer shell 101. A belt 402 is provided on the output shaft of the main motor 401, and the other end of the belt 402 is provided on the driving wheel 406. The axis of the output shaft of the main motor 401 is aligned with the axis of the connecting shaft between the rotating frame 403 and the support plate 405. When the main motor 401 drives the driving wheel 406 to rotate through the belt 402, the driving wheel 406 can drive the rotating ring 204 to rotate on the rubber belt 203, and the rotating ring 204 can also squeeze the driving wheel 406 to make the driving wheel 406 rotate around the axis of the connection between the rotating frame 403 and the support plate 405 to avoid the rotating ring 204.

[0030] Working principle: When this device is working, first, the outer surface of the glass bottle 106 needs to be processed. Then, the glass bottle 106 is placed on the rotating ring 204 by the numerical control bottle clamping machine. After the glass bottle 106 is placed, the clamping assembly will move to the extrusion bump on the conveying guide rail 201. When passing through the extrusion bump by the clamping assembly, the extrusion bump will move the inner clamping jaw 205 away from the axis of the rotating ring 204 through the extrusion sliding block 210 and the extrusion frustum 208, so that the inner clamping jaw 205 clamps the inner wall of the glass bottle 106, and in this way, the glass bottle 106 can be fixed on the clamping assembly. Then, the glass bottle 106 moves into the outer shell 101 along with the rubber belt 203. During the process of the glass bottle 106 approaching the shunt pipe 303, the clamping assembly will contact the driving wheel 406. Before the driving wheel 406 contacts the rotating ring 204, it is horizontally placed between the rubber belts 203, so that the rotating ring 204 can stably contact the driving wheel 406. After the driving wheel 406 contacts the rotating ring 204, the main motor 401 will drive the driving wheel 406 to rotate, causing the driving wheel 406 to drive the rotating ring 204 to rotate on the rubber belt 203. When the clamping assembly and the glass bottle 106 in the rotating state pass through the shunt pipe 303, the rubber belt 203 will stop driving the glass bottle 106 to move in the outer shell 101. At this time, the paint pump 102 is started to pump out the paint in the storage tank 104, and then it is transported to the shunt pipe 303 through the intermediate pipe 307 and evenly sprayed out in an atomized manner through the multiple atomizing nozzles 304 on the shunt pipe 303. Here, the glass bottle 106 rotates when the atomizing nozzles 304 spray the paint, so the paint on the surface of the glass bottle 106 will be evenly distributed. The spraying time of the atomizing nozzles 304 is also fixed. Therefore, after spraying the surface of the glass bottle 106, the paint pump 102 stops working, and the rubber belt 203 can continue to drive the glass bottle 106 to move in the outer shell 101. The rubber belt 203 will drive the glass bottle 106 to approach the heating wire 408. When passing through the position of the heating wire 408, since the next glass bottle 106 needs to be sprayed, the glass bottle 106 staying at the position of the heating wire 408 will stop. At this time, the glass bottle 106 will be heated by the hot air flow generated by the fan 407 and the extrusion frustum 208, so that the paint on the outer surface of the glass bottle 106 solidifies. After the next glass bottle 106 completes spraying, it will move out of the outer shell 101. The next station of the glass bottle 106 that moves out of the outer shell 101 is the numerical control bottle clamping machine for blanking. This process is the working process of spraying paint on the glass bottle 106.

[0031] When the device is in use, the mouth of the glass bottle 106 has limitations. The inner diameter of the mouth is generally 17 millimeters. If the diameter of the mouth changes, the corresponding clamping component can be replaced. At the same time, the position of the shunt pipe 303 in the outer shell 101 can also be adjusted according to the specific size of the glass bottle 106, and the adjustment is carried out through the horizontal lead screw 301 and the vertical lead screw 306.

[0032] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
