Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of soft capsule machinery, and particularly relates to a sediment separation type soft capsule pill press pump body sliding block oil supply mechanism. BACKGROUND
[0002] The soft capsule is a product type that is formed by spreading a glue skin made of gelatin or plant glue and glycerol and water mixed solution, and the glue skin is pressed into a capsule shell through two symmetrical pill pressing rollers, and the content is synchronously injected into the capsule shell through a pill press injection pump body. When the pill press is used to press the soft capsule, the injection pump body sliding block and the material extraction and injection rod are driven by the corresponding servo motors under the control of the main machine system program, and are precisely matched to extract the content material liquid from the pump body feed port of the pill press, and then the content material liquid is injected into the capsule shell pressed by the pill press through the pump body injection pipe and the injection nozzle. In the pressing process, whether the sliding block in the injection pump body can smoothly and stably run determines whether the soft capsule product with stable and qualified loading can be smoothly pressed. Whether the injection pump body sliding block can smoothly and stably run plays a key role in the lubricating oil supply of the injection pump body sliding block.
[0003] Before production, lubricating oil is added to the injection pump pool of the shot blasting machine. Currently, the lubricating oil supply for the pump body slider is provided by a lubricating oil pump that draws lubricating oil from the injection pump pool through a 4-6mm inner diameter oil pipe. Another 4-6mm inner diameter oil pipe connects the oil outlet of the lubricating oil pump to the oil inlet at the front end of the pump body slider, supplying oil to the slider. As the servo motor of the injection pump slider drives the slider to move back and forth repeatedly, lubricating oil continuously enters the lubricating oil channel of the pump body slider, lubricating its operation. The lubricating oil entering the pump body slider lubricating oil channel flows out from the lubricating oil channels at both ends of the pump body slider back into the injection pump pool. The lubricating oil in the injection pump pool is continuously drawn by the lubricating oil pump and injected into the lubricating oil inlet pipe of the pump body slider, thus forming a cycle. In this method of lubricating the shot press machine's injection pump pool as a sedimentation lubricating oil tank without an independent lubrication tank, it can operate normally when producing clear oil products. However, when producing suspension products mainly composed of mineral raw materials, such as calcium and magnesium mineral vitamin soft capsules, the calcium and magnesium mineral materials will continuously wear down the pump body and injection rod during repeated extraction and injection. After a long period of operation, the calcium and magnesium mineral materials will flow out during extraction or injection and enter the shot press machine's injection pump pool. As production volumes increase and time lengthens, mineral raw materials such as calcium and magnesium accumulate in the shot press machine's injection pump pool. If lubricating oil is still directly drawn from the injection pump pool, these materials will be drawn out simultaneously and injected into the slider lubricating oil pipe via the pump body's slider lubricating oil pump. Calcium and magnesium materials will accumulate in the oil pipes that draw lubricating oil from the injection pump pool and in the slider lubricating oil inlet pipe, eventually clogging the oil pipes. This results in the shot press machine's injection pump slider operating without lubricating oil, causing the resistance of the pump slider to gradually increase. Eventually, when the power provided by the shot press machine's injection pump servo motor can no longer drive the pump slider, shot pressing cannot proceed. Meanwhile, mineral raw materials such as calcium and magnesium, which enter the lubricating oil channel of the pump body along with the lubricating oil, will cause wear on the pump body slider and its connected components during operation. Over time, this wear will lead to the leakage of clear oil material directly from both ends of the pump body slider when switching from producing calcium and magnesium mineral vitamin soft capsules to producing clear oil products, resulting in serious material loss. At the same time, the filling volume of the shot-forming product will be unstable, and the error range will increase. Therefore, it is necessary to improve the lubricating oil supply system of the pump body slider of the existing sedimentation soft capsule shot-forming machine to avoid the above situations. Summary of the Invention
[0004] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a precipitation separation type soft capsule pelleting machine pump body slider oil supply mechanism, which can continuously provide lubricating oil for the operation of the injection pump body slider when producing soft capsules containing minerals such as calcium and magnesium and vitamins, thereby extending the precision operation time of the injection pump body slider and avoiding wear of the pelleting machine injection pump body due to lack of oil lubrication.
[0005] To solve the aforementioned technical problems, this application adopts the following technical solution:
[0006] A sedimentation-separation type oil supply mechanism for the slide block of a soft capsule compression machine includes a shot compression machine injection pump pool, a shot compression machine slide block lubricating oil pump, an oil inlet pipe and an oil outlet pipe disposed between the shot compression machine injection pump pool and the shot compression machine slide block lubricating oil pump. The oil outlet pipe is equipped with a lubricating oil tank, and the lubricating oil tank is equipped with a filter. The liquid in the shot compression machine injection pump pool enters the lubricating oil tank, is filtered by the filter, and then flows back to the shot compression machine slide block lubricating oil pump, which supplies oil to the shot compression machine slide block.
[0007] Preferably, the lubricating oil tank includes a return oil tank and an outlet oil tank that are partially interconnected. The oil inlet of the return oil tank is connected to the injection pump pool of the shot blasting machine through the oil extraction pipe, and the oil outlet of the outlet oil tank is connected to the lubricating oil pump of the slide block of the shot blasting machine through the oil extraction pipe. The filter is located in the outlet oil tank.
[0008] Preferably, the lubricating oil tank adopts a box structure, and a partition with a height lower than the box wall is provided in the middle of the lubricating oil tank. The interior of the lubricating oil tank is divided into the return oil tank and the outlet oil tank by the partition.
[0009] Preferably, the height of the partition is 3-5 cm lower than the height of the upper edge of the lubricating oil tank wall.
[0010] Preferably, the oil extraction pipe between the shot press injection pump pool and the return oil tank is a flexible hose with an inner diameter of 15-19mm.
[0011] Preferably, the filter is located at the outlet of the oil tank.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] By increasing the inner diameter of the oil extraction pipe from the injection pump pool to the return oil tank in the shot blasting machine, the extraction position of the lubricating oil pump on the pump body slider is changed. After sedimentation and filtration, oil is then supplied to lubricate the injection pump body slider. When producing soft capsules with minerals such as calcium and magnesium, this effectively avoids the situation where mineral materials enter the lubricating oil channel of the pump body slider, leading to wear of the injection pump body slider and its adjacent components due to prolonged operation, leakage of material from the injection pump body, and resulting material loss and unstable filling volume. It also prevents the gradual blockage of the lubricating oil pipeline, which leads to a decrease in lubrication during the operation of the injection slider of the pump body, eventually resulting in complete blockage. This can cause the injection slider to run without lubricating oil, increasing resistance, and the servo motor of the injection slider in the shot blasting machine being unable to drive the injection slider, resulting in pump body wear due to lack of lubrication. It can continuously provide lubricating oil for the injection slider during the production of mineral vitamin soft capsules such as calcium and magnesium, extending the service life of the injection slider and avoiding wear of the injection pump body of the shot blasting machine due to lack of lubrication.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0021] like Figure 1 The aforementioned oil supply mechanism for a sedimentation separation type soft capsule shot-forming machine pump body slider includes a shot-forming machine injection pump pool 3, a shot-forming machine pump body slider lubricating oil pump 1, an oil inlet pipe 2 and an oil extraction pipe 4 disposed between the shot-forming machine injection pump pool 3 and the shot-forming machine pump body slider lubricating oil pump 1. The oil extraction pipe 4 is equipped with a lubricating oil tank 5, and a filter 6 is provided inside the lubricating oil tank 5. The liquid in the shot-forming machine injection pump pool 3 enters the lubricating oil tank 5, is filtered by the filter 6, and then flows back to the shot-forming machine pump body slider lubricating oil pump 1, from which the shot-forming machine pump body slider lubricating oil pump 1 supplies oil to the shot-forming machine pump body slider.
[0022] Before the improvement, such as Figure 3As shown, the oil supply mechanism of the pump body slider of the sedimentation soft capsule pelleting machine includes a pelleting machine injection pump pool 3, a pelleting machine pump body slider lubricating oil pump 1, an oil inlet pipe 2 and an oil extraction pipe 4 located between the pelleting machine injection pump pool 3 and the pelleting machine pump body slider lubricating oil pump 1. The pelleting machine pump body slider lubricating oil pump 1 draws lubricating oil from the pelleting machine injection pump pool 3 through the oil extraction pipe 4 and enters the lubricating oil channel of the pelleting machine injection pump body slider through the slider lubrication inlet pipe 2 to lubricate the operation of the injection pump body slider. Then, it flows back to the pelleting machine injection pump pool 3 through the lubricating oil channel of the pelleting machine injection pump body slider. When producing soft capsule products such as calcium and magnesium, which are mainly minerals, this structure may cause the injection pump body slider and its adjacent components to wear after the mineral material enters the pump body slider lubricating oil channel due to long-term operation. This will eventually lead to material leakage in the pelleting machine injection pump body, resulting in material loss and unstable filling volume. Meanwhile, due to inherent lubrication issues, the lubricating oil pipeline is prone to blockage during long-term use. Therefore, a lubricating oil tank 5 with a filter 6 was added to the oil extraction pipe 4. Liquid from the shot blasting machine's injection pump pool 3 enters the lubricating oil tank 5, is filtered by the filter 6, and then flows back to the shot blasting machine's pump body slider lubricating oil pump 1 for operation. This fundamentally changes the lubricating oil extraction position of the shot blasting machine's pump body slider lubricating oil pump 1, ensuring that the oil is filtered before being supplied to the shot blasting machine's injection pump body slider for lubrication. When producing soft capsules containing minerals such as calcium and magnesium, this effectively prevents the mineral material from entering the pump body slider lubricating oil channel, which could lead to wear of the injection pump body slider and its adjacent components, leakage from the shot blasting machine's injection pump body, and consequently, material loss and unstable filling volume. It also prevents the gradual blockage of the lubricating oil pipeline, which leads to a decrease in lubrication during the operation of the pump body's injection slider, eventually resulting in complete blockage. This can cause the injection pump body's slider to operate without lubricating oil, increasing resistance, and the servo motor of the shot press machine being unable to drive the injection pump body's slider, leading to pump body wear due to lack of lubrication. It can continuously provide lubricating oil for the injection pump body's slider during the production of mineral and vitamin soft capsules such as calcium and magnesium, extending the precision operation time of the injection pump body's slider.
[0023] Further improvements include, for example Figure 2 As shown, the lubricating oil tank 5 includes a return oil tank 51 and an outlet oil tank 53 that are partially interconnected. The oil inlet of the return oil tank 51 is connected to the injection pump pool 3 of the shot press machine through the oil extraction pipe 4. The oil outlet of the outlet oil tank 53 is connected to the lubricating oil pump 1 of the slide block of the shot press machine through the oil extraction pipe 4. The filter 6 is installed in the outlet oil tank 53.
[0024] The lubricating oil tank 5 consists of a return oil tank 51 and an outlet oil tank 53, which are partially interconnected. The lubricating oil in the injection pump pool 3 of the shot press enters the return oil tank 51 through the oil extraction pipe 4 for sedimentation, and then enters the outlet oil tank 53 through the interconnected area. This makes the lubricating oil in the outlet oil tank 53 relatively clean. After secondary filtration by the filter 6, the lubricating oil flowing out of the outlet is free of impurities, resulting in less damage to the pump body slider of the shot press and less pipe blockage. This achieves the effect of continuously providing pure lubricating oil for the operation of the injection pump body slider, extending the precision operation time of the injection pump body slider.
[0025] A further improvement is made in that the lubricating oil tank 5 adopts a box structure, and a partition 52 with a height lower than the box wall of the lubricating oil tank 5 is provided in the middle of the lubricating oil tank 5. The interior of the lubricating oil tank 5 is divided into the return oil tank 51 and the outlet oil tank 53 by the partition 52.
[0026] The top of the lubricating oil tank 5 is an open-top structure. Inside, a return oil tank 51 and an outlet oil tank 53 are formed by a partition 52. The structure is simpler and the sealing is better. The return oil tank 51 is used to return oil from the injection pump pool 3 of the shot press. When the lubricating oil level in the return oil tank 51 rises above the middle partition 52, the lubricating oil that has settled in the return oil tank 51 enters the outlet oil tank 53 on the other side. After being filtered again by the filter 6 at the outlet of the outlet oil tank 53, the oil is discharged and supplied to the shot press pump body slider by the lubricating oil pump 1.
[0027] A further improvement is made in that the height of the partition 52 is 3-5cm lower than the height of the upper edge of the wall of the lubricating oil tank 5; and the oil extraction pipe 4 between the shot press injection pump pool 3 and the return oil tank 51 is a flexible hose with an inner diameter of 15-19mm.
[0028] The height of the baffle 52 is 3-5cm lower than the upper edge of the lubricating oil tank 5, which ensures the flow of internal lubricating oil and allows for deeper sedimentation. Currently, the inner diameter of the oil extraction pipe 4 from the shot blasting machine injection pump pool 3 to the shot blasting machine pump body slider lubricating oil pump 1 is 4-6mm. When producing materials such as calcium and magnesium minerals, these materials tend to deposit on the inner wall of the oil extraction pipe 4 between the shot blasting machine injection pump pool 3 and the return oil tank 51, causing blockage. Therefore, the oil extraction pipe 4 between the shot blasting machine injection pump pool 3 and the return oil tank 51 is replaced with a flexible hose with an inner diameter of 15-19mm. The return oil interface of the return oil tank 51 uses a stainless steel pipe with an external thread interface and an inner diameter of 13-17mm. By increasing the inner diameter of the oil extraction pipe 4, the blockage caused by the deposition of materials such as calcium and magnesium minerals on the inner wall of the oil extraction pipe 4 is avoided.
[0029] A further improvement is that the filter 6 is located at the outlet of the oil tank 53.
[0030] An oil filter 6 is installed on one side of the bottom of the oil outlet tank 53 of the double-box lubricating oil tank 5. The oil outlet of the lubricating oil tank 5 is connected to the oil inlet of the lubricating oil pump of the slide block of the shot press machine through a hose. Then, the oil outlet of the lubricating oil pump of the slide block of the shot press machine is connected to the oil inlet at the front end of the slide block of the pump body through a hose.
[0031] A filter 6 is installed at the bottom of the oil tank 53. The filter 6 is a conventional lubricating oil filter. The filter 6 is connected to a hollow tube that passes through the wall of the oil tank 53, forming an oil outlet port of the lubricating oil tank 5 on the outside of the oil tank 53. After the lubricating oil is filtered, it is supplied to the slide block of the shot press pump body by the lubricating oil pump, which can make the lubricating oil cleaner.
[0032] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
