Description

Technical Field

[0001] This utility model relates to the field of dispensing machine feeding technology, and more specifically, it relates to a dispensing machine feeding device. Background Technology

[0002] There are some significant problems and limitations in the existing glue application technology of dispensing machines. These problems not only affect production efficiency but may also affect product quality.

[0003] First, the glue application process in existing technologies is usually quite cumbersome, which seriously affects production efficiency. In some cases, the operation even requires manual squeezing of the glue bucket to apply the glue. This method is not only time-consuming and labor-intensive, but also makes it difficult to ensure the accuracy and consistency of the glue application. Manual operation is prone to uneven glue usage, sometimes resulting in too much or too little glue, which directly affects product quality. In addition, long-term repetitive manual operation may also lead to operator fatigue and increase the risk of operational errors. This method is particularly unsuitable for large-scale production, which seriously restricts the improvement of production efficiency and the stability of product quality.

[0004] Secondly, when it is necessary to replace the glue bucket or add glue to the glue bucket, the disassembly and installation process of the glue bucket in the existing technology is usually quite complicated. This process often requires multiple steps and the use of multiple different professional tools. This not only increases the operation time but also increases the operation difficulty. In a production environment where glue needs to be replaced or added frequently, this cumbersome operation will significantly reduce the overall production efficiency. In addition, the complicated disassembly and assembly process also increases the risk of operational errors, which may lead to improper installation of the glue bucket and affect the subsequent glue application quality. This time-consuming and labor-intensive operation method not only reduces production efficiency but also increases production costs.

[0005] Finally, although some equipment attempts to address the aforementioned issues by introducing quick disassembly and assembly mechanisms, these designs often suffer from structural simplicity and insufficient stability. While these simplified quick disassembly and assembly mechanisms may improve operational convenience in the short term, they introduce new problems during long-term use. Due to low structural stability, the glue bucket is prone to loosening during use and may even fall off. This instability not only affects the accuracy of glue dispensing but may also lead to glue leakage, resulting in material waste and environmental pollution. More seriously, if the glue bucket suddenly falls off during production, it may cause the production line to stop, resulting in severe economic losses. In addition, unstable glue bucket fixation may also affect the uniform output of glue, leading to unstable product quality. Utility Model Content

[0032] Please see Figures 1-6 A glue-applying device for a dispensing machine includes a fixed frame 1, characterized in that: a mounting frame 2 is detachably mounted on the top of the fixed frame 1, the glue-applying device is mounted on the fixed frame 1, and a quick-change device is mounted inside the mounting frame 2. The quick-change device includes a connecting pipe 3, a plug pipe 4, a plugging mechanism, an unlocking block 5, an unlocking sleeve 6, a sealing sleeve 7, and an unlocking groove 8. The connecting pipe 3 is fixedly mounted on the mounting frame 2, the plug pipe 4 is detachably inserted into the connecting pipe 3, the unlocking block 5 is slidably disposed in the unlocking groove 8, the unlocking sleeve 6 is rotatably sleeved on the outside of the connecting pipe 3, the sealing sleeve 7 is detachably installed in the connecting pipe 3, and the unlocking groove 8 is formed in the unlocking sleeve 6. A reinforcing mechanism is provided on the outside of the tube 3. The reinforcing mechanism includes an adapter 9, an adapter rod 10, a push spring 11, a mating plate 12, a mating hole 13, an insert rod 14, a slot 15, and a return spring 16. The adapter 9 is sleeved on the outside of the connecting tube 3. The adapter rod 10 is fixedly connected to one side of the adapter 9. The push spring 11 is movably sleeved on the outside of the adapter rod 10. The mating plate 12 is rotatably sleeved on the outside of the connecting tube 3. The mating hole 13 is opened on the mating plate 12. One end of the insert rod 14 is connected to the outer wall of the unlocking sleeve 6 through the return spring 16, and the other end of the insert rod 14 is inserted into the slot 15. Multiple slots 15 are opened on the outside of the connecting tube 3.

[0033] The insertion mechanism includes an insertion rod 17 and an insertion slot 18. The insertion rod 17 is fixedly connected to one side of the unlocking block 5. The insertion slot 18 is opened on the outside of the insertion tube 4, and one end of the insertion rod 17 is inserted into the insertion slot 18. Both one end of the insertion rod 17 and one side of the inner wall of the insertion slot 18 are treated with a chamfered structure.

[0034] A sealing ring 19 is provided on the outer side of the insertion tube 4, and a sealing groove 20 is provided on the inner side of the connecting tube 3 at the corresponding position. The sealing groove 20 is adapted to the sealing ring 19, and both the sealing ring 19 and the sealing sleeve 7 are made of flexible and sealable materials such as rubber.

[0035] In this embodiment, when the glue bucket 21 needs to be replaced or glue needs to be added to the glue bucket 21, the cylinder 22 is first driven, causing the piston rod 23 to move to the lowest point and be outside the glue bucket 21. Then, the mating plate 12 is rotated, causing the mating hole 13 to move. When the mating hole 13 moves to the position corresponding to the adapter rod 10, the adapter 9 is pushed, causing the adapter 9 to drive the adapter rod 10 through the mating hole 13. At the same time, the adapter 9 and the mating plate 12 will cooperate to squeeze the push spring 11 sleeved on the outside of the adapter rod 10. Then, the outer end of the insertion rod 14 will lose the limit of the adapter 9. Then, the unlocking sleeve 6 is rotated, causing the unlocking sleeve 6 to drive the insertion rod 14 to move. Then, the side wall of the slot 15 will press against the insertion rod 14. Due to the rounded corner design of the edge of the slot 15 and the end of the insertion rod 14, one end of the insertion rod 14 slides out of the slot 15, and the other end of the insertion rod 14 drives the return spring 16 to stretch. At the same time, the unlocking sleeve 6 drives the unlocking groove 8 opened on the inner side to rotate. Due to the special structural design of the unlocking groove 8 and the unlocking block 5, when the unlocking groove 8 rotates with the unlocking sleeve 6, the unlocking block 5 drives the insertion rod 17 to slide out of the insertion groove 18. Then, the glue bucket 21 is pulled down, so that the insertion tube 4 connected to the top of the glue bucket 21 can be removed from the inside of the connecting tube 3. When the glue bucket 21 needs to be replaced, it can be replaced directly. When glue needs to be added, glue is injected into the glue bucket 21 through the insertion tube 4. Then, the glue will push the extrusion plate 2 due to gravity. 4. Slide the plug tube 4 to the bottom of the glue tank 21. After replacing the glue tank 21 or completing the glue application, re-insert the plug tube 4 connected to the top of the glue tank 21 into the inner side of the connecting tube 3 set inside the mounting bracket 2. When one end of the plug tube 4 presses the sealing sleeve 7 against the inner wall of the connecting tube 3, rotate the unlocking sleeve 6 in the opposite direction. This causes the unlocking sleeve 6 to rotate and reset the unlocking groove 8. Then, the unlocking block 5 will drive the plug rod 17 connected on one side to re-insert into the plug groove 18. Due to the chamfered structure design on one side of the inner wall of the plug groove 18, when the plug rod 17 is fully inserted into the plug groove 18, the plug tube 4 will use the chamfer in the plug groove 18 to thoroughly press the sealing sleeve 7, ensuring the connection between the plug tube 4 and the connecting tube 3. To ensure a tight seal, multiple sealing rings 19 on the outer side of the connector 4 engage with corresponding sealing grooves 20 on the inner side of the connecting pipe 3, further enhancing the seal at the connection between the connecting pipe 3 and the connector 4. At this point, the return spring 16 drives the insert rod 14 to reset, and the other end of the insert rod 14 is inserted into the original slot 15. Then, the adapter 9 is released, and the push spring 11 pushes the adapter 9 to reset. The adapter 9 then drives the adapter rod 10 to slide back to its original position. After the push spring 11 has fully reset, the mating plate 12 is rotated again, causing the mating plate 12 to move the mating hole 13 to a position not corresponding to the adapter rod 10. This allows the adapter rod 10 and the mating plate 12 to provide stable support for the adapter 9, preventing it from sliding.Then, the inner wall of the fitting 9 will further limit the outer end of the insertion rod 14 to prevent it from moving. The insertion rod 14 will then cooperate with the slot 15 to limit the unlocking sleeve 6, preventing it from moving. This ensures the relative stability of the connection structure, preventing the glue bucket 21 from easily loosening or even falling off, thus ensuring the stable use of the equipment.

[0036] Please see Figures 1-3 As one embodiment of the gluing device: The gluing device includes a glue tank 21, a cylinder 22, a piston rod 23 and an extrusion plate 24. One end of the glue tank 21 is fixedly connected to the insertion pipe 4. The cylinder 22 is detachably installed inside the fixed frame 1. The piston rod 23 is located at the output end of the cylinder 22, and the other end of the piston rod 23 is in contact with the extrusion plate 24. The extrusion plate 24 is slidably disposed in the glue tank 21. The glue tank 21 is made of a rigid material.

[0037] The fixed frame 1 is detachably provided with a protective compartment 25, and a sliding frame 26 is provided on one side of the protective compartment 25. A protective plate 27 is slidably provided on the inner side of the sliding frame 26.

[0038] The protective chamber 25 is detachably equipped with a dispensing platform 28, and the dispensing platform 28 is equipped with a dispensing assembly 29.

[0039] One end of the connecting pipe 3 is connected to a corrugated pipe 30, and the connecting pipe 3 connected to one end of the dripping assembly 29 is connected to the connecting pipe 3 connected to one end of the mounting bracket 2 through the corrugated pipe 30.

[0040] A lead screw 31 is rotatably provided on one side of the protective chamber 25, and a screw sleeve 32 is detachably provided on one side of the protective plate 27. The screw sleeve 32 is movably sleeved on the outside of the lead screw 31 by means of threads. A motor 33 is installed at the top of the protective chamber 25, and the output end of the motor 33 is connected to the top of the lead screw 31.

[0041] More specifically, when using this equipment, first ensure that the protective plate 27 is in the raised position. Then, place the parts to be treated with adhesive onto the adhesive dispensing table 28. Next, open the adhesive dispensing assembly 29, allowing it to move and adjust to the appropriate position. Simultaneously, the adhesive dispensing assembly 29 will stretch or compress the bellows 30 via the connecting pipe 3. At the same time, open the motor 33 installed above the protective chamber 25, causing the motor 33 to drive the lead screw 31 to rotate. Since the screw sleeve 32 is movably connected to the lead screw 31 via threads, the screw sleeve 32 will then drive the protective plate 27 to slide downwards along the sliding frame 26, thereby closing the protective plate 27. Then, close the device. Motor 33 simultaneously opens cylinder 22. Cylinder 22 pushes extrusion plate 24 upward through piston rod 23 at output end. Extrusion plate 24 then squeezes the glue stored in glue tank 21. The glue then passes through connector 4 and connecting pipe 3 to bellows 30, and then through bellows 30 to connecting pipe 3 connected to input end of dispensing assembly 29. The glue is then dripped onto the component through dispensing assembly 29. After dispensing is completed, cylinder 22 is closed, and motor 33 is driven again to reverse. This causes protective plate 27 to rise and open through the cooperation of screw sleeve 32 and lead screw 31. Then dispensing assembly 29 is closed.

[0042] In summary, during the use or operation of the overall equipment: when it is necessary to replace the glue tank 21 or to add glue to the glue tank 21, firstly, drive the cylinder 22 so that the cylinder 22 drives the piston rod 23 to move to the lowest point and to the outside of the glue tank 21. Then, rotate the mating plate 12 so that the mating plate 12 drives the mating hole 13 to move. When the mating hole 13 moves to the position corresponding to the adapter rod 10, push the adapter 9 so that the adapter 9 drives the adapter rod 10 through the mating hole 13. At the same time, the adapter 9 and the mating plate 12 will cooperate to squeeze the push spring 11 sleeved on the outside of the adapter rod 10. Then, the outer end of the insertion rod 14 will lose the limit of the adapter 9. Then, rotate the unlocking sleeve 6 so that the unlocking sleeve 6 drives the insertion rod 14 to move. Then, the side wall of the slot 15 The insertion rod 14 will be squeezed at one end. Due to the rounded corner design of the edge of the slot 15 and the end of the insertion rod 14, one end of the insertion rod 14 will slide out of the slot 15, and the other end of the insertion rod 14 will drive the return spring 16 to stretch. At the same time, the unlocking sleeve 6 will drive the unlocking groove 8 opened on the inner side to rotate. Due to the special structural design of the unlocking groove 8 and the unlocking block 5, when the unlocking groove 8 rotates with the unlocking sleeve 6, the unlocking block 5 will drive the insertion rod 17 to slide out of the insertion groove 18. Then, the glue bucket 21 will be pulled down, so that the insertion tube 4 connected to the top of the glue bucket 21 can be removed from the inside of the connecting tube 3. When the glue bucket 21 needs to be replaced, it can be replaced directly. When glue needs to be added, glue is injected into the glue bucket 21 through the insertion tube 4, and then the glue will be pushed by gravity. The moving extrusion plate 24 slides to the bottom of the glue tank 21. After the glue tank 21 is replaced or the glue application is completed, the insertion tube 4 connected to the top of the glue tank 21 is re-inserted into the inner side of the connecting tube 3 set inside the mounting bracket 2. When one end of the insertion tube 4 presses the sealing sleeve 7 against the inner wall of the connecting tube 3, the unlocking sleeve 6 is rotated in the opposite direction, causing the unlocking sleeve 6 to rotate and reset the unlocking groove 8. Then, the unlocking block 5 will drive the insertion rod 17 connected on one side to re-insert into the insertion groove 18. Due to the chamfered structure design of one end of the insertion rod 17 into the inner wall of the insertion groove 18, when the insertion rod 17 is fully inserted into the insertion groove 18, the insertion tube 4 will use the chamfer in the insertion groove 18 to thoroughly press the sealing sleeve 7, ensuring that the insertion tube 4 and the connecting tube 3 are properly sealed. The sealing at the connection point is further enhanced by multiple sealing rings 19 on the outer side of the insertion tube 4 engaging with corresponding sealing grooves 20 on the inner side of the connecting tube 3. At this point, the return spring 16 drives the insertion rod 14 to reset, and the other end of the insertion rod 14 is inserted into the original slot 15. Then, the adapter 9 is released, and the push spring 11 pushes the adapter 9 to reset. The adapter 9 then drives the adapter rod 10 to slide back to its original position. After the push spring 11 has fully reset, the mating plate 12 is rotated again, causing the mating hole 13 to move to a position not corresponding to the adapter rod 10. This allows the adapter rod 10 and the mating plate 12 to provide stable support for the adapter 9, preventing it from sliding.Then, the inner wall of the fitting 9 will further limit the outer end of the insertion rod 14 to prevent it from moving. The insertion rod 14 will then cooperate with the slot 15 to limit the unlocking sleeve 6, preventing it from moving. This ensures the relative stability of the connection structure, preventing the glue bucket 21 from easily loosening or even falling off, thus ensuring the stable use of the equipment.

[0043] When using this equipment, first ensure the protective plate 27 is in the raised position. Then, place the parts to be treated with adhesive onto the adhesive dispensing table 28. Next, open the adhesive dispensing assembly 29, allowing it to move and adjust to the appropriate position. Simultaneously, the dispensing assembly 29 will stretch or compress the bellows 30 via the connecting pipe 3. At the same time, open the motor 33 mounted above the protective chamber 25, causing the motor 33 to drive the lead screw 31 to rotate. Since the screw sleeve 32 is connected to the lead screw 31 via threads, the screw sleeve 32 will cause the protective plate 27 to slide downwards along the sliding frame 26, thus closing the protective plate 27. Then, turn off the motor 37. 3. Simultaneously open cylinder 22. Cylinder 22 pushes extrusion plate 24 upward through piston rod 23 at output end. Extrusion plate 24 then extrudes the glue stored in glue tank 21. The glue then passes through pipe 4 and connecting pipe 3 to bellows 30, and then through bellows 30 to connecting pipe 3 connected to input end of dispensing assembly 29. The glue is then dripped onto the component through dispensing assembly 29. After dispensing is completed, close cylinder 22 and drive motor 33 again to reverse the direction of motor 33. This causes protective plate 27 to rise and open through the cooperation of screw sleeve 32 and lead screw 31. Then close dispensing assembly 29.
