Description

Technical Field

[0001] The present invention relates to the technical field of flame polishing, and in particular to a flame polishing device for pharmaceutical bottle processing. Background Art

[0002] Flame polishing is a technique that uses the high temperature of a flame to act on the surface of a material, and through heat, the surface of the material is melted to achieve a polishing effect; specifically, flame polishing is mainly applied to acrylic materials. By high-temperature treatment, the surface of the acrylic becomes as smooth as a mirror, increasing its transparency and gloss, and enhancing the texture and grade of the material. A flame polishing device is required during the processing of pharmaceutical bottles.

[0003] In the existing flame polishing device, the missing gear B is fixedly installed on the motor, and the missing gear B is meshed with the gear A. Thus, when the motor works, the connecting shaft rotates intermittently, realizing the intermittent polishing of the glass bottle. Also, since the three spray guns are fixedly installed on the left side of the mounting plate, the automatic polishing of the glass bottle is realized, improving the polishing efficiency of the glass bottle.

[0004] However, during the actual flame polishing process, it is necessary for the three spray guns to spray flames to cover the bottle body for polishing, which increases the cost and causes waste of some energy. Therefore, there is room for improvement. Summary of the Invention

Detailed implementation manners

[0031] The following will further describe the present invention in detail in conjunction with the attached Figures 1 - 10 drawings.

[0032] Referring to Figures 1 - 10 , an embodiment of the present invention discloses a flame polishing device for pharmaceutical bottle processing, including a protective box 1. A switching structure is arranged in the middle of the front surface of the protective box 1, and two sets of placing structures are arranged on the switching structure. A mounting plate 2 is installed in the middle of the upper surface of the protective box 1. A motor 3 is installed in the middle of the inner wall of the mounting plate 2. A first gear 4 is fixedly sleeved at the bottom end of the output shaft of the motor 3. The first gear 4 is an incomplete gear. A rotating column 5 is rotatably passed through the upper surface of the protective box 1 near the right side of the first gear 4. A clamping structure is arranged between the rotating column 5 and the placing structure. A second gear 6 is fixedly sleeved near the top end of the rotating column 5. A first rotating shaft 7 is rotatably connected to the upper surface of the protective box 1 near the left side of the first gear 4. A third gear 8 is sleeved on the first rotating shaft 7. An opening is formed in the middle of the left side surface of the protective box 1, and a first lifting plate 9 is slidably arranged in the opening. The first lifting plate 9 is in an "H" shape. The inner side walls of both sides of the first lifting plate 9 are respectively in close contact with the inner and outer side surfaces of the protective box 1. A spray gun 11 is arranged on the first lifting plate 9 through a flipping structure. One end of the spray gun 11 is installed with a pipeline 10. A first driving structure is arranged between the third gear 8 and the first lifting plate 9;

[0033] The first driving structure includes a fixing rod 12 connected to the upper edge of the third gear 8. A curved rod 13 is rotatably sleeved on the fixing rod 12. A connecting plate 14 is connected to the first lifting plate 9 near the top position. A first driving plate 15 is connected to the top end of the connecting plate 14. A first driving groove 19 is formed on the first driving plate 15. A limiting telescopic rod 17 is connected to the middle of the side of the first driving plate 15 close to the third gear 8. One end of the limiting telescopic rod 17 is connected to a U-shaped plate 16. Through rods 18 are fixedly passed through both ends of the U-shaped plate 16. The through rods 18 movably pass through the first driving groove 19. One end of the curved rod 13 is rotatably connected to the middle of the upper surface of the U-shaped plate 16. Start the spray gun 11 to perform flame polishing on the medicine bottle. When it is necessary to switch the polishing positions at different positions on the medicine bottle, start the motor 3 on the mounting plate 2 to drive the first gear 4 to rotate. When the first gear 4 rotates and meshes with the second gear 6, it drives the placing structure at the bottom end of the rotating column 5 and the whole medicine bottle to rotate, so as to automatically switch the polishing positions on the surface of the medicine bottle. When the first gear 4 disengages from the second gear 6 and the first gear 4 meshes with the third gear 8, the through rods 18 on the U-shaped plate 16 are driven by the curved rod 13 to reciprocate back and forth in the first driving groove 19 on the first driving plate 15. Through the extrusion of the through rods 18 on the groove wall of the first driving groove 19, the first lifting plate 9 is driven to drive the spray gun 11 to move up and down in the opening, so that under the action of one spray gun 11, the flame polishing can be carried out on various positions on the bottle body of the medicine bottle, reducing the processing cost.

[0034] See Figure 1 , Figure 5 and Figure 6 As shown in FIGS.

[0035] The flipping structure includes a through groove 20 formed in the middle of the first lifting plate 9. A turntable 21 is rotatably arranged in the through groove 20. A third rotating shaft is fixedly passed through the axis position of the turntable 21. First vertical grooves 22 are formed on both the left and right sides of the through groove 20 on the first lifting plate 9. Both ends of the third rotating shaft are respectively rotatably connected to the inner walls of the two first vertical grooves 22. A fourth gear 23 is fixedly sleeved on the part of the third rotating shaft in the two first vertical grooves 22. A second driving structure is arranged on the first lifting plate 9.

[0036] The third driving structure includes two T-shaped rods 29 respectively connected to the two side surfaces of the first lifting plate 9 near the second lifting plate 25. A reciprocating plate 28 is movably sleeved on the two T-shaped rods 29. A second insertion rod 32 is connected to one side surface of the reciprocating plate 28. A third driving groove 31 is formed in the protection box 1 near the reciprocating plate 28. One end of the second insertion rod 32 is movably inserted into the third driving groove 31. A first insertion rod 30 is fixedly passed through the middle of the reciprocating plate 28. One end of the first insertion rod 30 is movably inserted into the third driving groove 31. When the first lifting plate 9 moves up and down, it drives one end of the second insertion rod 32 to slide up and down in the third driving groove 31, pulling the reciprocating plate 28 to reciprocate back and forth on the T-shaped rods 29, and driving one end of the first insertion rod 30 to reciprocate back and forth in the second driving groove 27 on the second lifting plate 25, thereby driving the second lifting plate 25 on the first lifting plate 9 and driving the driving strip 26 to move up and down. Through the fourth gear 23, the third rotating shaft, the turntable 21 and the spray gun 11 as a whole swing up and down reciprocally, so that the flame sprayed by the spray gun 11 can better cover the medicine bottle, and thus the flame polishing of the medicine bottle is more thorough.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 9 , the switching structure includes a switching opening 35 formed in the middle of the front surface of the protection box 1. A switching plate 33 is arranged in the switching opening 35. A switching rod 36 is fixedly passed through the middle of the switching plate 33. The bottom end of the switching rod 36 is rotatably connected to the lower inner wall of the switching opening 35. The top end of the switching rod 36 rotatably passes through the upper surface of the protection box 1. A positioning structure is arranged between the switching rod 36 and the protection box 1;

[0038] The placing structure includes two bottom plates 34 connected to the lower parts of the front and rear sides of the switching plate 33. At one end of each bottom plate 34 away from the switching plate 33, a second rotating shaft 42 is rotatably installed. At the top of the second rotating shaft 42, a chassis 43 is installed. At the edge of the chassis 43, a plurality of vertical rods 44 are connected. At the top of the vertical rods 44, a top plate 58 is connected. In the middle of the top plate 58, a clamping column 47 is connected. The clamping column 47 is not roughened. An adjusting disc 45 is movably sleeved on the vertical rod 44 near the bottom end. A nut 46 is sleeved on one of the vertical rods 44 provided with threads. The nut 46 is pressed against the lower surface of the adjusting disc 45. Place the medicine bottle to be polished on the adjusting disc 45. The nut 46 can be rotated on the vertical rod 44 provided with threads to drive the adjusting disc 45 to move on the vertical rod 44, so that the top end of the medicine bottle is pressed against the top plate 58. In this way, when the top plate 58 and the medicine bottle as a whole are rotationally polished, the problem of the medicine bottle falling off can be avoided. And when the medicine bottle on the adjusting disc 45 in the protection box 1 is polished, the switching rod 36 can be rotated by using the fixing strip 39 to rotate the switching plate 33, and then the medicine bottle polished by the flame in the protection box 1 is rotated out of the protection box 1 for cooling, which is convenient for taking. At the same time, another medicine bottle on the adjusting disc 45 will be rotated into the protection box 1 to continue the flame polishing work, so as to improve the work efficiency.

[0039] See Figure 1 , Figure 2 , Figure 7 , Figure 9 and Figure 10 , the positioning structure includes a square rod 37 movably inserted into the top end of the switching rod 36. At the top of the square rod 37, a fixing strip 39 is installed. The positioning rods 40 are fixedly passed through both ends of the fixing strip 39. The bottom ends of the positioning rods 40 are movably inserted into the positioning grooves 41 opened on the top of the protection box 1. A spring 38 is sleeved on the square rod 37. The two ends of the spring 38 are respectively connected to the top end of the switching rod 36 and the fixing strip 39. After the adjusting disc 45 is switched, under the pulling force of the spring 38, the positioning rod 40 on the fixing strip 39 can be pulled to be inserted into the positioning groove 41 to position the switching plate 33 on the protection box 1;

[0040] The clamping structure includes an electric telescopic rod 48 installed at the middle of the top end of the rotating column 5. The top end of the output shaft of the electric telescopic rod 48 is connected with a lifting bar 49. Transverse grooves 51 are respectively formed near both ends of the lifting bar 49. A moving block 50 is slidably arranged in the transverse groove 51. A third insertion rod 55 is fixedly passed through the moving block 50 in a direction perpendicular to the rotating column 5. A vertical plate 56 is connected to the upper edge of the rotating column 5. Fourth driving grooves 57 are respectively formed at positions of the vertical plate 56 close to the two moving blocks 50. The third insertion rod 55 movably passes through the corresponding fourth driving groove 57. A through bar 52 is connected to the lower surface of the moving block 50. A through groove 53 for the through bar 52 to pass through is formed in the rotating column 5. An arc-shaped clamping block 54 is installed at the bottom end of the through bar 52. After the adjusting disc 45 and the medicine bottle are switched into the protection box 1, the electric telescopic rod 48 can be directly started to drive the lifting bar 49 to move downward, driving one end of the third insertion rod 55 to slide downward in the fourth driving groove 57. Thus, while driving the clamping block 54 to move downward, the two clamping blocks 54 move toward the side close to each other, so that the two clamping blocks 54 are clamped and fixed to the clamping column 47. In this way, when the motor 3 is started, the adjusting disc 45 and the medicine bottle can be smoothly driven to rotate intermittently for polishing work.

[0041] The implementation principle of a flame polishing device for pharmaceutical bottle processing in an embodiment of the present invention is as follows: First, start the motor 3 and the spray gun 11. The spray gun 11 sprays flames onto the pharmaceutical bottle for polishing. When the first gear 4 on the output shaft of the motor 3 is meshed and connected with the second gear 6, it drives the middle rotating column 5, the adjusting disc 45, and the entire pharmaceutical bottle to rotate, so that the flames sprayed from the spray gun 11 can polish various positions on the pharmaceutical bottle. When the first gear 4 is meshed and connected with the third gear 8, the adjusting disc 45 and the entire pharmaceutical bottle stop rotating. The third gear 8 drives the fixed rod 12 to rotate, and drives the through rod 18 on the U-shaped plate 16 to slide back and forth in the first driving groove 19 through the curved rod 13, thereby driving the first lifting plate 9 to drive the spray gun 11 to slide up and down in the opening, so that the spray gun 11 can perform flame polishing on various positions on the pharmaceutical bottle. And when the first lifting plate 9 moves up and down, it drives one end of the second insertion rod 32 to slide up and down in the third driving groove 31, pulling the reciprocating plate 28 to reciprocate back and forth on the T-shaped rod 29, and driving one end of the first insertion rod 30 to reciprocate back and forth in the second driving groove 27 on the second lifting plate 25, thereby driving the second lifting plate 25 on the first lifting plate 9 to drive the driving strip 26 to move up and down, driving the third rotating shaft, the turntable 21, and the entire spray gun 11 to swing up and down reciprocally through the fourth gear 23, so that the flames sprayed from the spray gun 11 can better cover the pharmaceutical bottle, thereby polishing the pharmaceutical bottle by flame more thoroughly, improving the polishing quality. When the polishing of the pharmaceutical bottle on the adjusting disc 45 in the protective box 1 is completed, the motor 3 stops working. Start the electric telescopic rod 48 to drive the lifting strip 49 to move upward. Utilize the upward sliding of the third insertion rod 55 in the fourth driving groove 57 to drive the two clamping blocks 54 to move upward and disengage from the clamping column 47. At this time, utilize the fixed strip 39 to pull the square rod 37, and pull out one end of the positioning rod 40 from the positioning groove 41 to release the positioning of the switching plate 33 in the protective box 1. Then utilize the fixed strip 39 to rotate the switching plate 33 to turn out the polished pharmaceutical bottle in the protective box 1 for cooling, and switch the pharmaceutical bottle on another adjusting disc 45 into the protective box 1 to continue polishing, greatly improving the working efficiency, and the operation is also simple and convenient.

[0042] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
