Description

Technical Field

[0001] This utility model belongs to the field of liquid silicone supply technology, specifically relating to a liquid silicone supply device. Background Technology

[0002] Liquid silica gel is a material that is very sensitive to the temperature of the storage environment. Its properties will deteriorate or age due to excessively high temperatures, resulting in a decline in performance; while excessively low temperatures may cause it to freeze, damaging its structure, and even after thawing, its original properties cannot be restored.

[0003] Traditional feeding devices, which rely on manual labor, are not only time-consuming and labor-intensive, but also difficult to achieve precise control over the feeding. Although existing feeding devices have achieved automation, they still cannot accurately measure and distribute the required amount of material when the feeding amount needs to be adjusted. Excessive material supply will not only increase costs, but may also have a negative impact on product quality. Insufficient material supply will make it difficult to meet the original production needs, leading to a decrease in production efficiency and even interruption of the production process.

[0004] Therefore, a feeding device is designed to adjust the required amount of liquid silicone and achieve precise feeding. Utility Model Content

[0025] Example 1

[0026] like Figures 1 to 5 The liquid silicone feeding device shown has a discharge chamber 101 on the rear side of the top of a workbench 1. A main shaft 2 is rotatably mounted on the left side of the top of the workbench 1. A first circular plate 3 is connected to the top of the main shaft 2. The top of the first circular plate 3 has symmetrical first feed inlets 4 on the left and right sides. A first feed cylinder 5 is located at the bottom of the first feed inlet 4. A sleeve 6 is mounted on the upper part of the main shaft 2. A second circular plate 7 is slidably mounted on the sleeve 6. The second circular plate 7 has symmetrical second feed inlets 8 on the left and right sides. A second feed cylinder 9 is located at the bottom of the second feed inlet 8. A sealing cover 11 is connected to the inner side of each second feed cylinder 9 by a hinge 10. An arc-shaped sealing ring 12 is located inside the sealing cover 11. The inlets of the second feed cylinders 9 on the second circular plate 7 are slidably mounted on the outer side of the first feed cylinders 5. A telescopic rod 13 is located on the top of the worktable 1, behind the main shaft 2. A guide plate 14 is connected to the end of the telescopic rod 13. An installation ring 15 is installed on the top of the guide plate 14. A guide ring 16 is connected to the top of the installation ring 15. An open groove 17 is recessed on the left side of the bottom of the guide ring 16. The guide plate 14 is slidably sleeved on the outside of the sleeve 6 through a guide hole 18. An extension plate 19 extends from the inside of the sealing cover 11. A roller 20 is rotatably mounted on the top of the inner side of the extension plate 19. A half gear 22 is rotatably mounted on the right side of the worktable 1 through a drive component 21. A free-spinning ring 23 is staggered on the outer side of the bottom of the half gear 22. A full gear 24 is provided at the bottom of the main shaft 2. A free-spinning groove block 25 is provided at the bottom of the full gear 24. A constant temperature block 26 is provided in the discharge bin 101.

[0027] This invention maintains the temperature of liquid silicone between 5°C and 35°C by installing a constant temperature block 26 at the bottom of the inner wall of the discharge hopper 101, thus preserving its original physical and chemical properties, preventing deterioration or aging, and maintaining the usability of the supplied liquid silicone. Through the coordinated operation of the main shaft 2, the first circular plate 3, the first feed cylinder 5, the second circular plate 7, and the second feed cylinder 9, this invention achieves precise control of the feeding amount to meet the needs of different quantities. Through the cooperation of components such as the telescopic rod 13, the guide plate 14, the mounting ring 15, and the guide ring 16, as well as the rotation of the drive component 21 (such as a motor), this invention automates the feeding process, improving efficiency and accuracy. Through the cooperation of the half gear 22 and the full gear 24, this invention enables intermittent 180° rotation of the first circular plate 3 and the second circular plate 7, achieving automated control of loading and unloading, and improving the accuracy of the feeding.

[0028] Example 2

[0029] like Figures 1 to 5 The liquid silicone feeding device shown includes a workbench 1, with a discharge chamber 101 located on the rear top of the workbench 1. The discharge chamber 101 stores all the liquid silicone. It should be noted that liquid silicone is highly sensitive to temperature. If the storage temperature is too high, the liquid silicone is prone to deterioration or aging, leading to a decrease in performance. Conversely, if the temperature is too low, the liquid silicone will freeze, causing structural damage. Even after thawing, its original properties cannot be restored. Therefore, in this embodiment, a temperature-regulating block 26 is provided at the bottom of the inner wall of the discharge chamber 101 to help maintain a stable temperature of 5℃ to 35℃ within the discharge chamber 101, thus preserving the original physical and chemical properties of the liquid silicone and preventing deterioration or aging.

[0030] A main shaft 2 is rotatably mounted on the top left side of the workbench 1. A first circular plate 3 is connected to the top of the main shaft 2. The top of the first circular plate 3 has symmetrical first feed ports 4 on the left and right sides. A first feed cylinder 5 is located at the bottom of the first feed port 4. The first feed cylinder 5 is hollow. When the main shaft 2 rotates, it can drive the first circular plate 3 to rotate. The rotation of the first circular plate 3 drives the first feed port 4 to continuously align with the discharge port of the discharge bin 101. At this time, the valve of the discharge port opens to discharge liquid silicone. The liquid silicone enters the first feed cylinder 5 through the discharge port to achieve initial feeding. After the first feed cylinder 5 is filled with enough liquid silicone, the valve of the discharge port closes and no longer discharges liquid silicone.

[0031] A sleeve 6 is provided on the upper part of the spindle 2. A telescopic rod 13 is also provided on the top of the worktable 1, located behind the spindle 2. A guide plate 14 is connected to the telescopic end of the telescopic rod 13. The front side of the guide plate 14 is slidably fitted onto the outside of the sleeve 6 through a guide hole 18. Simply put, when the telescopic rod 13 extends or retracts, it causes the guide plate 14 to move up and down on the sleeve 6. The guide plate 14 and the sleeve 6 are only in a fitted contact relationship; therefore, when the spindle 2 rotates, causing the sleeve 6 to rotate, it will not affect the guide plate 14. Furthermore, when a mounting ring 15 is provided on the top of the guide plate 14, and the mounting ring 15 is also slidably fitted onto the outside of the sleeve 6, when the telescopic rod 13 extends or retracts, it causes the mounting ring 15 to move up and down on the sleeve 6 via the guide plate 14. A guide ring 16 is connected to the top of the mounting ring 15, meaning that the telescopic rod 13 will cause all its components to be fixed to the outside of the sleeve 6.

[0032] A second circular plate 7 is slidably mounted on the sleeve 6. The second circular plate 7 has second feed inlets 8 symmetrically arranged on the left and right sides. A second feed cylinder 9 is provided at the bottom of the second feed inlet 8. It should be noted that the inner diameter of the first feed cylinder 5 is equal to the outer diameter of the first feed inlet 4, the inner diameter of the second feed cylinder 9 is equal to the outer diameter of the second feed inlet 8, and the outer diameter of the first feed cylinder 5 is equal to the inner diameter of the second feed inlet 8. The guide ring 16 abuts against the second circular plate 7, so that it is located above the guide ring 16, and at the same time, it drives the second feed inlets 8 on the second circular plate 7 to slide on the outside of the first feed cylinder 5 respectively.

[0033] Since the first feed cylinder 5 is located inside the second feed inlet 8, the extension and retraction of the telescopic rod 13 can be achieved by moving the guide ring 16 up and down, thereby adjusting the height of the second circular plate 7. The up and down movement of the second circular plate 7 can control the actual feeding space of the first feed cylinder 5 and the second feed cylinder 9. Understandably, the rotation of the first circular plate 3 drives the first feed inlet 4 to continuously align with the discharge port of the discharge bin 101. At this time, the valve of the discharge port opens, discharging liquid silicone. The liquid silicone enters the first feed cylinder 5 through the discharge port and then enters the second feed cylinder 9, completing one feeding cycle. The operator only needs to control the extension and retraction of the telescopic rod 13 to control the actual feeding space of the first feed cylinder 5 and the second feed cylinder 9. In practical applications, the operator can adjust the actual feeding space of the first feed cylinder 5 and the second feed cylinder 9 according to the required amount of material to be fed at one time, so that the feeding of the first feed cylinder 5 and the second feed cylinder 9 reaches the required amount, achieving automatic feeding while also ensuring the even distribution of the feeding amount.

[0034] On the other hand, when the main shaft 2 rotates and drives the first circular plate 3 to rotate, the second circular plate 7 can be pushed to rotate through the first feed cylinder 5. The inner side of the second feed cylinder 9 is connected to a sealing cover 11 through a hinge 10. An extension plate 19 extends from the inner side of the sealing cover 11. A roller 20 is rotatably provided on the top inner side of the extension plate 19. Correspondingly, an open groove 17 is recessed on the left side of the bottom of the guide ring 16. The open groove 17 cooperates with the roller 20. For ease of understanding, as shown in Figure*, the second feed cylinder 9 on the right rotates to the bottom of the discharge hopper 101 to fill with liquid silicone. At this time, the roller 20 contacts the bottom of the guide ring 16, causing the sealing cover 11 to be pressed against the bottom of the second feed cylinder 9, thus sealing the bottom opening of the second feed cylinder 9 and coordinating with the state of the liquid silicone. Meanwhile, the second feed cylinder 9 on the left rotates until the roller 20 contacts the open groove 17. At this time, the roller 20 is no longer under force, causing the sealing cover 11 to no longer be under the force of the roller 20. Subsequently, under the influence of the gravity of the liquid silicone filled in the second feed cylinder 9, the sealing cover 11 opens to discharge the liquid silicone, completing the liquid silicone supply for other steps.

[0035] More specifically, after the second feed cylinder 9 on the right finishes filling the liquid silicone, the second feed cylinder 9 on the left finishes discharging the liquid silicone. At this time, the main shaft 2 rotates again, causing the first circular plate 3, the first feed cylinder 5, the second circular plate 7, and the second feed cylinder 9 to rotate again. The second feed cylinder 9 on the right, which contains liquid silicone, is under the force of the roller 20 and the guide ring 16, and its lower sealing cover 11 will remain closed until it moves to contact the open groove 17 to discharge the filled liquid silicone. After the second feed cylinder 9 on the left rotates, it will cause the roller 20 to gradually move out of the open groove 17, and the roller 20 will gradually rotate under the force of the guide ring 16, causing its upper sealing cover 11 to gradually rotate, sealing the second feed cylinder 9, and moving it again to the bottom of the discharge bin 101 to fill the material. This process is repeated.

[0036] The sealing cover 11 is also equipped with an arc-shaped sealing ring 12. The arc-shaped sealing ring 12 has a certain hardness, which can help it be inserted into the second feed cylinder 9 more accurately and quickly complete the sealing of the second feed cylinder 9.

[0037] Example 3

[0038] like Figures 1 to 5 The liquid silicone feeding device shown includes a worktable 1. A half gear 22 is rotatably mounted on the right side of the worktable 1 via a drive component 21. This drive component 21 can be an electrical device such as a motor that can drive the half gear 22 to rotate continuously. A full gear 24 is provided at the lower part of the main shaft 2. That is, the drive component 21 drives the half gear 22 to rotate. One rotation can drive the full gear 24 to rotate half a rotation. In this way, the main shaft 2 can drive the first circular plate 3 and the second circular plate 7 to rotate intermittently by 180°, so as to realize the automated control of loading and unloading.

[0039] The bottom outer side of the half gear 22 is provided with staggered idler rings 23, and the bottom of the full gear 24 is provided with an idler groove block 25. When the half gear 22 rotates to the point where it is no longer meshing with the full gear 24, the idler rings 23 will continue to rotate and make frictional contact with the idler groove block 25. This can increase the stability of the full gear 24 when it is not meshing, and prevent the full gear 24 from continuing to rotate due to inertia, which would prevent the feed port from being aligned with the discharge bin 101, thus ensuring the accuracy of the feeding.
