Description

Technical Field

[0001] The invention relates to the technical field of coating production, in particular to a coating can for filling water-based coatings. Background Art

[0002] Any paint that uses water as a solvent or dispersion medium can be called a water-based paint. The processed water-based paint is generally contained in barrels made of metal or plastic, which have certain sealing and corrosion resistance properties. Therefore, a filling machine is needed to fill the water-based paint into the barrel. However, the processed water-based paint is generally placed in a paint ton tank before filling, which is not only convenient for transportation, but also can be connected to the filling machine.

[0003] The prior art discloses a canned water-based paint transport barrel with publication number CN118306655A. By placing one transport barrel on top of another transport barrel, the two transport barrels can be kept connected through a connecting mechanism to complete the fixed connection of the container body. After the connecting mechanism fixes the container body, the connecting positioning assembly will lock the position of the container body to ensure that the upper container body will not detach due to sliding during storage or transportation, thereby ensuring the stability and safety of storage.

[0004] Although it can ensure safety during transportation, there are still some defects in the actual use process. Due to the lack of quick-change structure at the outlet of the paint tank, when the water-based paint in the tank is exhausted, workers are required to use tools to remove the joint with the filling machine and use a forklift to replace the new paint tank for installation. This is not only laborious, but also the replacement process requires shutdown operation, so it takes a long time to wait, which will greatly reduce the filling efficiency of the device.

[0005] Therefore, a paint can for filling water-based paint is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1-8The paint tank for filling water-based paint shown in the figure comprises a tank body 1 and a conversion box 4 connected to the suction end of the filling machine. A discharge pipe 2 is fixedly connected to the bottom of the tank body 1, and a valve 3 is provided on the discharge pipe 2. Branch pipes 5 for connecting to two tank bodies 1 are bolted to the openings on both sides of the conversion box 4. An elbow 6 is fixedly connected to the branch pipe 5 on the side away from the branch pipe 5. A plug 7 is provided between the elbow 6 and the discharge pipe 2. A bellows 8 is fixedly connected between the plug 7 and the elbow 6. A sleeve 9 is fixedly connected to the side away from the branch pipe 5, and the end of the sleeve 9 is longer than the end of the plug 7. A fixing mechanism for initially fixing the position is provided on the sleeve 9. Slide grooves 10 are provided on the upper and lower sides of the outer wall of the sleeve 9. An adjusting ring 11 is provided on the outer wall of the plug 7. Pull plates 12 are fixedly connected to the outer wall of the adjusting ring 11 and at the position corresponding to the slide groove 10. Guide rollers 13 are rotatably connected to the upper and lower sides of the outer wall of the sleeve 9. The inner side of the conversion box 4 is rotatably connected to the outer wall of the sleeve 9. A semicircular blocking block 18 is connected, which is a mature technology in the prior art. When the blocked branch pipe 5 is blocked, the rear side of the semicircular blocking block 18 passes through the conversion box 4 and is rotatably connected to the double-groove winding roller 15. A rotating sealing device is provided at the connection between the semicircular blocking block 18 and the double-groove winding roller 15, which not only ensures the normal connection and rotation between them, but also ensures that the water-based paint in the conversion box 4 will not flow out. The main rope 16 is wound around the inner side of the double-groove winding roller 15, and the side wall of the pull plate 12 is fixedly connected with a branch rope 17. The other end of the branch rope 17 passes through the guide roller 13 and is fixedly connected to one end of the main rope 16. An upper spring 20 is fixedly connected between the inner side of the slide groove 10 and the side wall of the pull plate 12. The upper spring 20 facilitates the pulling plate 12 to quickly reset. The end of the intubation tube 7 is fixedly connected with a conical sealing ring 22. Through the setting of the conical sealing ring 22, the tighter the intubation tube 7 is inserted, the more the conical sealing ring 22 is inserted, and the better the sealing effect.

[0030] The other end of the main rope 16 is fixedly connected to the inner side of the double-groove winding roller 15, and the L-shaped plate 14 is fixedly connected to the rear side of the conversion box 4. The drive motor 19 is fixedly connected to the rear side of the L-shaped plate 14. The output end of the drive motor 19 passes through the L-shaped plate 14 and is fixedly connected to the side wall of the double-groove winding roller 15, and the winding directions of the two main ropes 16 are arranged in opposite directions. The fixing mechanism includes an upper right-angle block 23, and three slide bars 25 are slidably connected through the outer wall of the sleeve 9. A fixing ring 26 is fixedly connected to the outer wall of the discharge pipe 2. Six upper right-angle blocks 23 are arranged, and the six upper right-angle blocks 23 are fixedly connected to the side close to the slide bar 25, and the inclined surface of the upper right-angle block 23 is arranged on the side close to the discharge pipe 2. A lower spring 24 is fixedly connected between the outer wall of the slide bar 25 and the outer wall of the sleeve 9;

[0031] When in use, first connect the conversion box 4 to the suction end of the filling machine, then transport the can body 1 with water-based paint to the filling machine by forklift, and place the can body 1 on the L-shaped positioning block 21. At this time, under the action of the L-shaped positioning block 21, the discharge pipe 2 will be aligned with the sleeve 9, and then the can body 1 is pushed by the forklift to insert the discharge pipe 2 into the sleeve 9. During the insertion process, the fixing ring 26 on the discharge pipe 2 will squeeze the inclined surface of the upper right-angle block 23, thereby pushing the upper right-angle block 23 outward to move, and at the same time drive the slide bar 25 to slide , and stretch the lower spring 24. Then, when the tank body 1 moves to the position against the L-shaped positioning block 21, the discharge pipe 2 will be completely inserted into the sleeve 9, and at the same time, the upper right-angle block 23 moves out from above the fixing ring 26, thereby releasing the squeezing of the upper right-angle block 23. Then, under the elastic force of the lower spring 24, the slide bar 25 and the upper right-angle block 23 are pushed downward, so that the upper right-angle block 23 is against the side wall of the fixing ring 26, thereby preliminarily limiting the position between the sleeve 9 and the discharge pipe 2. Repeat the above operation for the sleeve 9 at the other end to be preliminarily fixed;

[0032] Then, when the control drive motor 19 is started, the double-groove winding roller 15 is driven to rotate. Since the two main ropes 16 on the double-groove winding roller 15 are wound in opposite directions, one main rope 16 will be driven to wind up and the other main rope 16 will be unwound. Therefore, the wound main rope 16 will pull the two branch ropes 17 to move around the guide roller 13, thereby pulling the pull plate 12 to slide inside the slide groove 10, and at the same time drive the adjustment ring 11 and the insertion tube 7 to move, and stretch the upper spring 20. Since the upper right-angle block 23 is stuck on the rear side of the fixing ring 26, it will pull the conical sealing ring 22 into the discharge pipe 2, and at the same time stretch the corrugated tube 8, and complete. The automatic sealing connection between the insertion tube 7 and the discharge tube 2 is completed, and the main rope 16 unwound on the other side will repeat the above operation in reverse. At the same time, the rotation of the double-groove winding roller 15 will drive the semicircular blocking block 18 to rotate, thereby rotating the blocking position to the branch tube 5 on the side of the docking release, realizing automatic conversion, and then the valve 3 on the discharge tube 2 can be opened, and the filling machine can be controlled to start and the water-based paint in the tank body 1 is pumped out for filling. This can be repeated, which can save a lot of time (it should be noted here that the drive motor 19 needs to be controlled to reverse during the subsequent conversion and cannot continue to rotate), greatly improving the filling efficiency of the device.

[0033] In order to improve the convenience of the paint tank docking process, a pair of L-shaped positioning blocks 21 for limiting are provided under the tank body 1, and the L-shaped positioning blocks 21 are fixedly connected to the ground next to the filling machine. Through the setting of the L-shaped positioning blocks 21, the docking position of the discharge pipe 2 and the insert pipe 7 and the sleeve 9 can be limited, thereby improving the convenience of the docking process.

[0034] The fixing mechanism includes an upper right-angle block 23, three slide bars 25 are slidably connected to the outer wall of the sleeve 9, a fixing ring 26 is fixedly connected to the outer wall of the discharge pipe 2, six upper right-angle blocks 23 are provided, and the six upper right-angle blocks 23 are all fixedly connected to the side close to the slide bar 25, and the inclined surface of the upper right-angle block 23 is provided on the side close to the discharge pipe 2, and a lower spring 24 is fixedly connected between the outer wall of the slide bar 25 and the outer wall of the sleeve 9.

[0035] In order to limit the position of the sleeve 9 on the discharge pipe 2, three limit rods 37 for limiting are fixedly connected to the outer wall of the fixing ring 26, and the side away from the three limit rods 37 is set to a smooth arc surface. Through the setting of the limit rods 37, the position of the sleeve 9 can be limited to ensure that the sleeve 9 and the discharge pipe 2 remain concentric to avoid affecting the subsequent insertion of the conical sealing ring 22. At the same time, the side away from the limit rods 37 is set to a smooth arc surface, which facilitates the better insertion of the discharge pipe 2 into the sleeve 9 during docking, thereby improving the convenience of the device docking process.

[0036] In order to facilitate the rapid outward pulling of the three slide bars 25 to release the position restriction of the sleeve 9, a positioning ring 27 is fixedly connected to the outer wall of the sleeve 9, a sliding ring 28 is slidably connected to the outer wall of the sleeve 9 and is located between the positioning ring 27 and the slide bar 25, and a plurality of return springs 29 are fixedly connected between the sliding ring 28 and the positioning ring 27. The side walls of the slide bar 25 are all fixedly connected to round rods 30, and lower right-angle blocks 31 are provided below the round rods 30. A connecting plate 32 is fixedly connected between the sliding ring 28 and the lower right-angle block 31, and a plurality of push plates 38 are fixedly connected to the outer wall of the sliding ring 28 at equal intervals. The push plates 38 facilitate the sliding ring 28 to move, thereby improving the convenience of the device.

[0037] After the conical sealing ring 22 is pulled out from the end of the discharge pipe 2, the connecting plate 32 and the lower right-angle block 31 can be driven to slide by pushing the sliding ring 28, and the reset spring 29 can be compressed at the same time, so that the round rod 30 is gradually squeezed upward by the inclined surface of the lower right-angle block 31 to slide upward, and then the sliding rod 25 is pushed to drive the upper right-angle block 23 to move upward, so that the upper right-angle block 23 slides out of the fixing ring 26, and the lower spring 24 is compressed at the same time, so that the three sliding rods 25 can be pushed to slide upward at the same time, quickly releasing the position restriction of the sleeve 9 and improving the convenience performance of the device.

[0038] In order to adjust the position of the automatic docking according to the size of the coating tank discharge pipe 2, a screw 34 is threadedly connected to the side wall of the adjusting ring 11, a plurality of jacks 36 are equidistantly provided on the outer wall of the insert tube 7 and at positions corresponding to the screw 34, a rotating plate 35 is fixedly connected to the side wall of the screw 34, and an adjusting groove 33 is provided on the side wall of the sleeve 9 and at positions corresponding to the screw 34. The setting of the adjusting groove 33 avoids obstruction to the normal movement of the rotating plate 35, and at the same time facilitates workers to rotate the rotating plate 35 for adjustment;

[0039] When the docking position needs to be adjusted according to the size adjustment of the paint tank discharge pipe 2, the screw 34 can be driven to rotate by rotating the rotating plate 35, so that the screw 34 spirally moves outward and moves out of the insertion hole 36, and then the position restriction of the adjustment ring 11 is released, and then the insertion tube 7 can be pushed to move in the adjustment ring 11, so that the corresponding insertion hole 36 moves to the side of the screw 34, and the rotating plate 35 can be rotated in the opposite direction to insert the screw 34 into the insertion hole 36, thereby adjusting the extrusion position of the tapered sealing ring 22, and the discharge pipes 2 with different inner diameters can be docked.

[0040] The basic principles, main features and advantages of the present invention are shown and described above.

[0041] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
