Description

Technical Field

[0001] The invention discloses a bottle cap processing device, in particular to an automatic glue dispensing and pressing machine for bottle caps. Background Art

[0002] After the bottle cap is processed and formed, a layer of plugging gasket needs to be placed inside the bottle cap to ensure that the bottle cap and the bottle body are sealed after being connected. After the plugging gasket is placed in, glue is generally injected through a glue dispenser, and then the glue is evenly filled on the plugging gasket by squeezing to ensure a fixed connection between the plugging gasket and the bottle cap. Finally, it is ensured that the plugging gasket and the bottle cap are fixed without deviation and the connection with the bottle body is stable. In the prior art, the plug pads are piled up in the delivery tube, and the negative pressure suction head adsorbs the plug pads, and rotates and moves them downward to be delivered into the bottle cap to fit with the glue. However, in the delivery tube, blocking objects are placed to prevent the plug pads from falling directly. The plug pads are used to receive the plug pads. When the suction head adsorbs and removes the plug pads, the suction force of the suction head and the downward force of the suction head directly pull the soft plug pads downward so that the plug pads are deformed and separated from the delivery tube. The plug pads thus taken out may be deformed, offset or loosened, resulting in misalignment when placed in the bottle cap. Therefore, the present application proposes a new solution, which makes the suction head stable when adsorbing the plug pads and stable and unobstructed when moving outwards, thereby ensuring that the inserted plug pads will not be offset.

Detailed implementation manners

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] An automatic cap dispensing and pressing machine, as Figures 1 - 7As shown in the figure, it includes a device main body 1, a conveying component 2 and a blanking component 3. A rotating disk 4 connected to the conveying component 2 and the blanking component 3 is provided on the device main body 1. The rotating disk 4 is rotatably connected to the device main body 1, and a placement part 5 for accommodating the placement of bottle caps is provided on the rotating disk 4. A glue injection pipe 6 is provided on the device main body 1. A feeding device 7 and an extrusion device 8 are provided at the rear end of the glue injection pipe 6. In a normal device, glue is injected into the bottle caps through the glue injection pipe 6, and the bottle caps are driven by the rotation of the rotating disk 4 to the lower end of the feeding device 7 at the next process. At the same time, the bottle cap gaskets are placed on the conveyor and sent to the extrusion device 8 to extrude the gaskets and the bottle caps, so that the bottle caps and the gaskets are tightly bonded and fixed. Then, it continues to rotate and enters the blanking component 3 for blanking to complete the processing. An annular fixing part 9 for extruding the bottle caps into the placement part 5 is provided on the outer circle of the rotating disk 4. The fixing part 9 is in a disconnected state between the conveying component 2 and the blanking component 3. A support plate 10 is provided at the bottom of the rotating disk 4. A push plate 11 for pushing the bottle caps away from the rotating disk 4 is provided at the support plate 10 at the blanking component 3. The push plate 11 is inclined. The push plate 11 is fixedly connected to the support plate 10 and is arranged in a staggered manner with the rotating disk 4. The feeding device 7 includes a storage object 12 for stacking bottle cap gaskets at the top and a support bracket 13 connected to the device main body 1. The support bracket 13 is connected to the storage object 12. A conveying pipe 14 for accommodating the downward movement of the bottle cap gaskets is connected to the lower end of the storage object 12. A moving part 15 is slidably connected to the support bracket 13. A suction head 16 for sucking the bottle cap gaskets is rotatably connected to the moving part 15. An extension part 17 for accommodating the embedding of the suction head 16 is provided at the lower end of the conveying pipe 14. A magnetic block 18 is slidably connected to the bottom of the extension part 17. A blocking piece 19 for receiving the bottle cap gaskets is provided at the bottom of the conveying pipe 14. The blocking piece 19 is slidably connected to the conveying pipe 14. A receiving part 20 is provided at the upper end of the conveying pipe 14 above the blocking piece 19. The receiving part 20 is arranged in a staggered manner with the blocking piece 19. A driving component for driving the movement and switching of the receiving part 20 and the blocking piece 19 is provided in the suction head 16, the conveying pipe 14 and the extension part 17. The driving component includes a strong magnet 21 provided at the lower end of the suction head 16. The strong magnet 21 repels the magnetic block 18 magnetically and pushes the magnetic block 18 to move. A pull rope 22 is connected to the rear end of the magnetic block 18. A winding part 23 for winding the pull rope 22 is rotatably connected in the extension part 17. A spring 24 for pushing the winding part 23 to rotate is provided between the winding part 23 and the extension part 17. A pull rope 25 is connected to the rear end of the blocking piece 19. The other end of the pull rope 25 is also connected to the winding part 23. The rear ends of the blocking piece 19 and the receiving part 20 are connected by a connecting rope 26.

[0016] After using this device normally, glue is injected into the bottle cap, and then the bottle cap is sent to the rotating disk 4 by the conveying component 2 and embedded in the placement part 5. At the same time, the rotating disk 4 rotates to push the bottle cap to move to the fixing part 9. The fixing part 9 cannot move, but the bottle cap can move, and is pushed by the fixing part 9 to completely fit in the placement part 5, ensuring that after the bottle cap moves to the feeding device 7 of the next process, it will directly face the suction head 16 and the conveying tube 14. The device sensor senses this and controls the moving part 15 to move up, and the suction head 16 rotates toward the conveying tube 14 and is embedded in the extension part 17. At the same time, the strong magnet 21 at the lower end of the suction head 16 moves to the extension part 17. The magnetic block 18 is relatively close to the magnetic block 18, and because the magnetic force of the strong magnet 21 is relatively large, the repulsive force with the magnetic block 18 is also relatively large, and it will push the magnetic block 18 to move backward so that the magnetic block 18 will compress the spring 28, and cancel the pulling of the pull rope 22. The pulling force of the pull rope 22 disappears, and the elastic force of the spring 24 in the winding member 23 will push the winding member 23 to rotate and rewind the pull rope 22, and at the same time, it will also rewind the misplaced pull rope 25, and drive the blocking piece 19 to move backward so that the blocking piece 19 will compress the spring 27, and cancel the blocking of the bottle cap plug pad. At the same time, the suction head 16 is embedded in place of the blocking piece 19 to bear the bottle cap plug pad, thereby ensuring that the bottle cap plug pad will not fall off due to separation from the blocking piece 19. Secondly, when the blocking piece 19 moves backward, the connecting rope 26 is also relaxed, and the pulling on the receiving piece 20 is cancelled, so that the receiving piece 20 is pushed forward by the spring 3 29, and the first bottle cap plug pad is separated from the second plug pad through the triangular inclined surface, and the blocking piece 19 continues to move backward, and the receiving piece 20 is also continuously embedded and the plug pad above the second bottle cap plug pad is synchronously pushed upward to separate from the first plug pad, and at the same time, after waiting for the blocking piece 19 to be completely embedded in the conveying pipe 14, the receiving piece 20 supports the remaining plug pads, thereby preventing the subsequent plug pads from falling off. Secondly, the blocking piece 19 is driven backward by the magnetic block 18 to cancel the blocking of the plug pad, ensure that the suction head 16 is completely in contact with the plug pad, and then suck it under negative pressure to avoid excessive pulling when the plug pad is adsorbed and moved downward, and also to avoid the situation where the plug pad is blocked and needs to be pulled out by pulling force to cause the plug pad to deform. Through the above arrangement, when taking out the plug pad, not much force is required, and the removal is smooth and will not shift. The plug pad can be placed in the bottle cap smoothly without moving, and the plug pad will not be deformed, and the position relative to the bottle cap is ensured to avoid shifting when placed in.

[0017] The pull cord one 22 and the pull cord two 25 are arranged in a staggered manner. A first spring 27 for pushing the blocking piece 19 to move is provided between the blocking piece 19 and the conveying pipe 14. A second spring 28 is provided between the magnet 18 and the extension part 17. A third spring 29 for pushing the blocking piece 19 to move forward is provided at the rear end of the blocking piece 19. The elastic force of the second spring 28 is less than the repulsive force between the strong magnet 21 and the magnet 18, and the elastic force of the clockwork spring 24 is less than the elastic force of the second spring 28. The elastic force of the first spring 27 is less than the elastic force of the clockwork spring 24, and the elastic force of the third spring 29 is less than the elastic force of the first spring 27. One end of the receiving part 20 facing the bottle cap gasket is triangular. A guide wheel 31 for guiding and restricting the connecting rope 26 is provided in the conveying pipe 14. On the contrary, after the suction head 16 is driven by the moving part 15 to move downward and the strong magnet 21 is separated from the extension part 17, the pushing force on the magnet 18 is cancelled. At this time, the elastic force of the second spring 28 at the rear end of the magnet 18 is greater than the force of the clockwork spring 24 and greater than the adsorption force between the magnet 18 and the extension part 17. Thus, the magnet 18 will be pushed back to its original position, and at the same time, the pull cord one 22 will be pulled, so that the clockwork spring 24 is compressed and the winding of the pull cord two 25 is cancelled, making the pull cord two 25 loose. And the first spring 27 can push the blocking piece 19 back to its original position. When the blocking piece 19 returns to its original position, because the elastic force of the first spring 27 is greater than the elastic force of the third spring 29, the connecting rope 26 can be driven to pull the receiving part 20 to move backward along the guide wheel 31, thereby cancelling the blocking of the remaining bottle cap gaskets, so that the bottle cap gaskets can move downward again and fit on the blocking piece 19.

[0018] A storage member 12 is provided with a first cylinder 30 at the upper end of a conveying pipe 14 for pushing a bottle cap gasket downward. A sensor is provided at the rear end of the conveying pipe 14 with respect to a receiving member 20. The cylinder is provided with a controller for receiving signals from the sensor. A lever 32 is rotatably connected within the storage member 12 for pushing the bottle cap gasket into the conveying pipe 14. Secondly, when the receiving member 20 moves and then resets and moves backward again, when the sensor senses it, it will output a signal to the controller, and the controller will activate the first cylinder 30 to cause the first cylinder 30 to move downward and embed into the conveying pipe 14, thereby pushing downward the bottle cap gasket pushed upward by the receiving member 20 to abut against a blocking piece 19. This setting avoids the situation where some gaskets cannot move downward, ensuring that every time the gasket is pushed upward by the receiving member 20, it can move downward again and fit against the blocking piece 19, ensuring that the suction head 16 can still adsorb the gasket when it is embedded next time. Finally, the controller controls the first cylinder 30 to reset once, and the sensor is set to output a signal to the controller when it senses the receiving member 20 moving backward. This device is an existing technology that can be set through a pre-programmed procedure. Secondly, after the first cylinder 30 pushes once, the lever 32 at the top will rotate once and push a new gasket into the conveying pipe 14. A plurality of tubes are provided within the storage member 12 at the top, and a number of gaskets are placed within the tubes. When moving, these interconnected tubes are pushed to move, thereby avoiding the situation where the soft gaskets are pushed and scattered, resulting in jamming when the lever 32 moves. Secondly, the inner diameter of the tube is slightly larger than the inner diameter of the conveying pipe 14. If the gasket within the conveying pipe 14 is not flush with the storage member 12 and is lower than the surface of the storage member 12 when it moves to the conveying pipe 14, the newly moved gasket will re-enter the conveying pipe 14. After the first cylinder 30 is driven, the lever 32 is opened, thereby ensuring that the next time the first cylinder 30 moves downward, a new gasket can be pushed into the conveying pipe 14, achieving an automatic filling effect.

[0019] The squeezing device 8 includes a second bracket 33 connected to the device main body 1. A second cylinder 34 is provided on the second bracket 33. A squeezing block 35 for embedding the bottle cap squeezing gasket is provided on the second cylinder 34. An annular block 36 is provided on the outermost circle of the squeezing block 35, and the annular block 36 is slidably connected to the squeezing block 35. A third cylinder 37 connected to the annular block 36 is fixedly provided at the side of the squeezing block 35 on the second bracket 33. The third cylinder 37 starts earlier than the second cylinder 34. Finally, the gasket is smoothly placed into the bottle cap through the above structure and fits with the internal glue. The rotating disk 4 is driven regularly once to convey the bottle cap with the gasket placed to the opposite side of the squeezing device 8. At this time, when the sensor senses it, it will output a signal and control the second cylinder 34 and the third cylinder 37 on the second bracket 33 to drive. And the third cylinder 37 is driven first to push the annular block 36 to move downward to be in a misaligned state with the squeezing block 35, and it is not flush with the squeezing block 35. Then the second cylinder 34 is turned on and drives the squeezing block 35 to move downward at the same time. Thus, the annular block 36 and the squeezing block 35 are embedded into the bottle cap. Because the annular block 36 protrudes, it will first contact the gasket when embedded in the bottle cap and squeeze the outermost circle of the squeezing gasket. Then the squeezing block 35 moves downward and is embedded. By the embedding of the squeezing block 35, the glue between the gasket and the bottle cap will be completely flattened and filled on the entire gasket, making the connection flat. At the same time, through the prior extrusion restriction of the outermost circle, the entire outer circle of the gasket is sealed to prevent the glue from flowing out from the outer circle. After being blocked by the annular block 36, the squeezing block 35 moves downward to squeeze the glue in the middle evenly and disperse it around, which will not cause the glue to overflow. Thus, it better ensures that all the glue is inside the gasket. Compared with the prior art, when the entire squeezing block 35 moves downward to squeeze the glue, it may disperse around and cause the glue to overflow outside the gasket to the surrounding of the bottle cap. Thus, after the glue solidifies, it will affect the use. By the sequential extrusion of the annular block 36 and the squeezing block 35, the risk of overflow is reduced, the yield rate is increased, and the appearance of defective products is reduced. Finally, after the squeezing block 35 finishes squeezing, it is flush with the annular block 36 and moves upward again. Thus, the bottle cap squeezed by the squeezing block 35 continues to be conveyed to the blanking assembly 3. At this time, it is separated from the blockage of the fixing member 9. At the same time, after rotation, the bottle cap contacts the push plate 11. Because the push plate 11 is inclined and the rotating disk 4 rotates continuously, the bottle cap moves, so that the bottle cap moves from the lowest point in contact with the push plate 11 to the highest point and is pushed out by the push plate 11 from the placing part 5 into the blanking assembly 3. Thus, an assembly effect is achieved.
