Description

Technical Field

[0001] The invention belongs to the technical field of coating machines, and in particular relates to a coating machine spray gun pull rod braking device. Background Art

[0002] The working principle of the coating machine is to rotate the pot clockwise to make the sugar-coated tablets roll, slide, rub and grind in the pot, and the spray gun sprays a uniform fine mist of coating liquid on the surface of the sugar-coated tablets. A hot air blower is also provided in the coating machine. The hot air blower blows hot air to make the coating liquid quickly condense on the surface of the sugar-coated tablets, thereby forming sugar-coated tablets. Most of the coating liquid spray guns in the existing technology are fixed on the spray gun fixing rod, which is inconvenient to adjust the position of the spray gun.

[0003] A search revealed a patent application with the publication number CN201120193746.0, which discloses a sliding coating spray gun device. The spray gun device moves back and forth with a slide bar, and when entering and exiting the coating pot, the entire spray gun device can be moved in and out of the coating pot by simply pulling it back and forth. However, this application still has the following drawbacks:

[0004] 1. The spray gun device only realizes the stretching movement of the spray gun frame, and cannot be rotated and adjusted. The movable area of ​​the spray gun is still very limited;

A support seat 6 is slidably connected to the position of the slide bar 2 near the pull rod 3. The outer wall of the pull rod 3 is provided with a fixing component for fixing the transition tube 13.

[0039] A rectangular hole 29 is formed inside the fixing plate 17 , and a control component for releasing the brake of the transition pipe 13 is provided inside the rectangular hole 29 .

[0040] In one aspect of this embodiment, Figure 5-7As shown, the lifting assembly includes two support plates 19 symmetrically arranged at the bottom of the rectangular box 18 and slidably connected. The two support plates 19 are provided with a lifting groove 32 for use with the spray gun support rod 7 on one side. A triangular groove 33 and a positioning groove 34 are provided on one side of the two support plates 19. When the pull rod 3 approaches the shell 14, the push rod 41 is inserted into the inside of the triangular groove 33. Since the inner wall of the triangular groove 33 is inclined, the sliding ring 22 and the push rod 41 move downward and stretch the first tension spring 23. At this time, the sliding ring 22 drives the card rod 25 to move vertically downward and insert it into the inside of the card groove 26. At the same time, the positioning rod 2 1 is stuck into the interior of the positioning groove 34 to prevent the pull rod 3 from shaking. A third tension spring 35 is fixedly connected between one side of the support plate 19 and the inner wall of one side of the rectangular box 18. The pull rod 3 can be pulled laterally, and the pull rod 3 drives the transition pipe 13 and the spray gun support rod 7 to move laterally. The spray gun support rod 7 drives the spray gun assembly 8 to move laterally. At this time, the spray gun assembly 8 and the spray gun support rod 7 can be moved out of the shell 14. At the same time, the spray gun support rod 7 moves inside the lifting groove 32. The lifting groove 32 lifts the spray gun support rod 7, which again ensures the stability of the spray gun support rod 7. At this time, the spray gun support rod 7 cannot rotate.

[0041] In one aspect of this embodiment, Figure 4 As shown, the fixing assembly includes a fixing ring 24 fixedly sleeved on the outer wall of the pull rod 3, a sliding ring 22 is slidingly sleeved on the outer wall of the pull rod 3, a first tension spring 23 is fixedly connected to the sliding ring 22 and the fixing ring 24, the first tension spring 23 is sleeved on the pull rod 3, the bottom of the sliding ring 22 is fixedly connected to two symmetrically arranged clamping rods 25, the top of the transition tube 13 is provided with a clamping groove 26 used in conjunction with the clamping rod 25, one side of the fixing ring 24 is provided with a positioning rod 21 used in conjunction with the positioning groove 34, and one side of the sliding ring 22 is fixedly connected to a push rod used in conjunction with the triangular groove 33 Rod 41, when it is necessary to rotate the spray gun support rod 7, you can continue to pull the pull rod 3 horizontally. At this time, the slider 4 pushes the U-shaped plate 16, and the U-shaped plate 16 drives the rectangular plate 28 to move horizontally. The rectangular plate 28 drives the extrusion spring 27. At this time, the rectangular plate 28 no longer blocks the limit plate 38. The limit plate 38 and the rectangular rod 37 move vertically upward under the elastic force of the compression spring 39, and then the rectangular rod 37 no longer engages with the rectangular groove 36, and the braking state of the support plate 19 is released. At this time, the two support plates 19 move away from each other under the tension of the third tension spring 35 and no longer support the spray gun support rod 7.

[0042] In another aspect of this embodiment, Figure 4-7As shown, the control component includes a rectangular plate 28 slidably connected to the inner wall of the rectangular hole 29, and a U-shaped plate 16 is fixedly connected to one side of the rectangular plate 28. The same spring 27 is fixedly connected between one side of the rectangular plate 28 and the inner wall of one side of the rectangular hole 29. The U-shaped plate 16 is used in conjunction with the slider 4. At the same time, the rectangular plate 28 no longer blocks the rectangular box 18. At this time, the rectangular box 18 moves vertically upward under the tension of the second tension spring 30, and can drive the two support plates 19 to move vertically upward. The support plate 19 no longer blocks the spray gun support rod 7 and the spray gun assembly 8. The spray gun support rod 7 can be rotated through the slewing ring bearing 5, which is convenient for subsequent maintenance and overhaul and easy to use.

[0043] Example 2

[0044] Improvements based on Example 1: Refer to the attached Figure 8 A rectangular groove 36 is provided on the top of the support plate 19, and two symmetrically arranged second grooves 40 and two symmetrically arranged first grooves 31 are provided on the top of the rectangular box 18. The first groove 31 is connected to the second groove 40, and a rectangular rod 37 is slidably connected to the inside of the first groove 31. The top of the rectangular rod 37 is fixedly connected to a limiting plate 38 used in conjunction with the second groove 40, and a plurality of compression springs 39 are fixedly connected between the bottom of the limiting plate 38 and the top of the first groove 31.

[0045] Example 3

[0046] Improvements based on Example 1: Refer to the attached Figure 7-10 The slide rod 2 is cylindrical, and the support seat 6 is provided with a limiting groove adapted to the slide rod 2. The support seat 6 includes a fixed seat body 9 and a roller 10 hingedly connected to the fixed seat body 9. The slide rod 2 is arranged on the roller 10 and the roller 10 is provided with a limiting groove adapted to the slide rod 2. The roller 10 is connected to the fixed seat body 9 through a connecting bearing 11. A limiting roller 12 is provided at the position above the fixed seat body 9. The spray gun assembly 8 consists of a spray gun bracket and a plurality of spray guns. The transition pipe 13 is L-shaped, having a horizontal connecting rod and a vertical connecting rod that are connected to each other at one end and perpendicular to each other. The horizontal connecting rod is connected to the spray gun support rod 7, and the upper end of the vertical connecting rod has a connecting end face 15 connected to the slewing ring bearing 5, and there is a downward hanging compensation inclination angle of X° between the connecting end face 15 and the horizontal plane, and X° is 5°.

[0047] The use process and working principle of the technical solution of the present invention are as follows:

[0048] When in use, the pull rod 3 can be pulled laterally, and the pull rod 3 drives the transition pipe 13 and the spray gun support rod 7 to move laterally, and the spray gun support rod 7 drives the spray gun assembly 8 to move laterally. At this time, the spray gun assembly 8 and the spray gun support rod 7 can be moved out of the shell 14. At the same time, the spray gun support rod 7 moves inside the lifting groove 32. The lifting groove 32 lifts the spray gun support rod 7, which again ensures the stability of the spray gun support rod 7. At this time, the spray gun support rod 7 cannot rotate;

[0049] When it is necessary to rotate the spray gun support rod 7, the pull rod 3 can be continued to be pulled horizontally. At this time, the slider 4 pushes the U-shaped plate 16, and the U-shaped plate 16 drives the rectangular plate 28 to move horizontally. The rectangular plate 28 drives the extrusion spring 27. At this time, the rectangular plate 28 no longer blocks the limit plate 38. The limit plate 38 and the rectangular rod 37 move vertically upward under the elastic force of the compression spring 39, and then the rectangular rod 37 is no longer engaged with the rectangular groove 36, releasing the braking state of the support plate 19. At this time, the two support plates 19 move away from each other under the tension of the third tension spring 35 and no longer support the spray gun support rod 7;

[0050] At the same time, the rectangular plate 28 no longer blocks the rectangular box 18. At this time, the rectangular box 18 moves vertically upward under the tension of the second tension spring 30, which can drive the two support plates 19 to move vertically upward. The support plates 19 no longer block the spray gun support rod 7 and the spray gun assembly 8. The spray gun support rod 7 can be rotated through the slewing ring bearing 5, which is convenient for subsequent maintenance and overhaul and easy to use.

[0051] When the pull rod 3 approaches the shell 14, the push rod 41 is stuck in the inside of the triangular groove 33. Since the inner wall of the triangular groove 33 is inclined, the sliding ring 22 and the push rod 41 move downward and stretch the first tension spring 23. At this time, the sliding ring 22 drives the card rod 25 to move vertically downward and be stuck in the inside of the card groove 26. At the same time, the positioning rod 21 is stuck in the inside of the positioning groove 34, which prevents the pull rod 3 from shaking and is easy to use.
