Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging machinery and equipment technology, specifically to a viscous substance transfer system. Background Technology

[0002] In the production process of Lanrui peptide gel injector implant, the drug solution is very viscous and requires a pressure of more than 1 MPa to be propelled. The material needs to be transferred from the mixing tank to the transfer tank for easy filling. During the transfer process, the connection between the mixing tank and the transfer tank needs to be evacuated first to avoid air in the pipeline affecting the filling process.

[0003] like Figure 1 As shown, the existing vacuuming structure for the connection section between the mixing tank and the transfer tank involves connecting a connecting pipe between the mixing tank 1 and the transfer tank 2, and then connecting a vacuuming pipe to the side wall of the connecting pipe. The vacuuming pipe is connected to a vacuuming device, which evacuates the connection section between the mixing tank and the transfer tank through the vacuuming pipe. However, before connecting to the next transfer tank, residual material in the connecting pipe and the vacuuming pipe needs to be cleaned before evacuation can be performed again and the material transfer can be completed, resulting in material waste, which greatly increases costs, especially for very expensive materials. Furthermore, the connection to the vacuuming pipe can easily contaminate the material. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a viscous material transfer system that reduces material waste, lowers production costs, and is less likely to contaminate materials.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A method for transferring a viscous substance, employing a viscous substance transfer system, comprising a first tank and a second tank, each equipped with a piston for pressurizing and propelling the material, and an openable and closable vacuum chamber. The first tank has a discharge end, the second tank has a feed end, and the vacuum chamber is equipped with a locking mechanism. The viscous substance transfer method includes the following steps: S1. Open the vacuum chamber and connect the discharge end and the feed end through the locking mechanism; S2. Close the vacuum chamber to seal the connection between the discharge end and the feed end within the vacuum chamber. S3. The locking mechanism adjusts the connection between the discharge end and the feed end to form a gap that allows air bubbles to pass through while preventing material from passing through; S4. Set the vacuuming time for the vacuum chamber; S5. The discharge end and the feed end are locked by the locking mechanism to seal the connection between the discharge end and the feed end; S6. Under the action of the pistons in the first tank and the second tank, the material in the first tank enters the second tank through the discharge end and the feed end; S7. After the material in the second tank reaches the set amount, open the vacuum chamber and release the locking mechanism.

[0006] A viscous material delivery system includes a first tank and a second tank, each having a piston for pressurizing and moving the material, and an openable and closable vacuum chamber. The first tank has a discharge port, and the second tank has a feed port. The vacuum chamber is equipped with a locking mechanism for detachably connecting the discharge port and the feed port and for adjusting the tightness of the connection between the discharge port and the feed port. A vacuum port is provided on one side of the vacuum chamber.

[0007] As a further improvement to the above technical solution: The vacuum chamber includes a box body and a box cover. The box body is provided with an inlet and an outlet. The box cover is detachably installed at the inlet and an outlet. The locking mechanism is installed inside the box body. The vacuum port is located on the box body or the box cover.

[0008] The side wall of the box is provided with a through opening, and the first tank is provided with a discharge pipe. The discharge pipe passes through the through opening and is sealed to the through opening. The discharge end is located at the end of the discharge pipe away from the first tank.

[0009] The box is equipped with a support for holding the second tank, and the inlet and outlet are larger than the second tank.

[0010] The support and locking mechanism are both located at the bottom of the box, and the inlet and outlet are located at the top of the box.

[0011] The through-hole is a U-shaped opening facing upwards, and a sealing plate is provided above the discharge pipe at the through-hole. The sealing plate is clamped between the discharge pipe and the box cover.

[0012] The locking mechanism includes a fixed base, a first hoop, a second hoop, and a locking drive. The fixed base is located inside the vacuum chamber. The first hoop and the second hoop are arranged opposite to each other on the fixed base to clamp the discharge end and the feed end. The locking drive is used to drive the first hoop and the second hoop to open and close.

[0013] The first hoop is fixed on the fixed base, and one end of the second hoop is hinged to the first hoop and the other end is connected to the locking drive.

[0014] The locking drive is a telescopic drive, and the telescopic end of the telescopic drive is hinged to the other end of the second hoop via a connecting rod. The second hoop is located above the first hoop.

[0015] Compared with the prior art, the advantages of this utility model are: This invention discloses a method for transferring viscous materials. It employs a combination of a vacuum chamber and a locking mechanism to create a vacuum at the junction of the discharge and inlet ends. During vacuuming, the locking mechanism forms a gap at the junction that allows air bubbles to pass through while preventing material from passing through. This prevents material from being extracted during vacuuming, reducing material waste and lowering production costs. Furthermore, by using a locking mechanism within the vacuum chamber to connect the discharge and inlet ends and adjusting the tightness at the junction, material contamination is less likely compared to using a connecting pipe.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] This viscous material transfer method and apparatus is used for the transfer of viscous materials, such as Lanrepeptide gel injector implants. During the production of Lanrepeptide gel injector implants, the liquid is very viscous and requires a pressure of over 1 MPa to be propelled. The material needs to be transferred from the mixing tank (first tank 1) to the transfer tank (second tank 2) for easy filling. During the transfer process, the connection section between the mixing tank and the transfer tank needs to be evacuated first to avoid air in the pipeline affecting the filling process.

[0033] Example 1: A method for transferring viscous substances, employing, for example Figures 2 to 10 The illustrated viscous material transfer system includes a first tank 1 and a second tank 2, each equipped with a piston 8 for pressurizing and propelling the material, and an openable and closable vacuum chamber 3. The first tank 1 has a discharge end 11, the second tank 2 has a feed end 21, and the vacuum chamber 3 is equipped with a locking mechanism 4. The viscous material transfer method includes the following steps: S1. Open the vacuum chamber 3 and connect the discharge end 11 and the feed end 21 through the locking mechanism 4; S2. Close the vacuum chamber 3 to seal the connection between the discharge end 11 and the feed end 21 inside the vacuum chamber 3. S3. The locking mechanism 4 adjusts the connection between the discharge end 11 and the feed end 21 to form a gap that allows air bubbles to pass through and prevents material from passing through. S4. Set the vacuuming time for vacuum chamber 3; S5. The discharge end 11 and the feed end 21 are locked by the locking mechanism 4, so that the joint between the discharge end 11 and the feed end 21 is sealed. S6. Under the action of the piston 8 in the first tank 1 and the second tank 2, the material in the first tank 1 enters the second tank 2 through the discharge end 11 and the feed end 21. S7. After the material in the second tank 2 reaches the set amount, open the vacuum chamber 3 and release the locking mechanism 4.

[0034] This method for transferring viscous materials employs a vacuum chamber 3 and a locking mechanism 4 to create a vacuum at the junction of the discharge end 11 and the feed end 21. During vacuuming, the locking mechanism 4 creates a gap at the junction of the discharge end 11 and the feed end 21 that allows air bubbles to pass through while preventing material from passing through. This prevents material from being extracted during vacuuming, reducing material waste and lowering production costs. Furthermore, by using the locking mechanism 4 within the vacuum chamber 3 to connect the discharge end 11 and the feed end 21, and by adjusting the tightness of the junction between the discharge end 11 and the feed end 21, material contamination is less likely compared to using a connecting pipe to connect the discharge end 11 and the feed end 21.

[0035] In S3, the gap formed at the junction of the discharge end 11 and the feed end 21 is used to transfer a viscous material. Because the material being transferred is extremely sticky, even with a large gap, the viscous material will not move along the discharge end 11 due to the negative pressure environment of the vacuum chamber 3 without the piston 8 of the first tank 1 pushing it. Therefore, when a vacuum is applied at the junction of the discharge end 11 and the feed end 21, the viscous material cannot reach the gap. Thus, the gap at the junction of the discharge end 11 and the feed end 21 allows air bubbles to pass through, but prevents material from passing through. Furthermore, the gap can be adjusted to be appropriately small so that even if the viscous material passes through the gap, it cannot pass through it.

[0036] Example 2: Figures 2 to 10 An embodiment of the viscous material transfer system of this utility model is shown. The viscous material transfer system of this embodiment includes a first tank 1 and a second tank 2, both having pistons 8 for pressurizing and moving the material, and an openable and closable vacuum chamber 3. The first tank 1 has a discharge end 11 at its outlet, and the second tank 2 has a feed end 21 at its inlet. The vacuum chamber 3 is provided with a locking mechanism 4, which is used to detachably connect the discharge end 11 and the feed end 21 and to adjust the tightness of the connection between the discharge end 11 and the feed end 21. A vacuum port 7 is provided on one side of the vacuum chamber 3.

[0037] The transfer process of this viscous material transfer system is as follows: First, open the vacuum chamber 3 and connect the discharge end 11 and the feed end 21 through the locking mechanism 4; Second, close the vacuum chamber 3 to seal the connection between the discharge end 11 and the feed end 21 within the vacuum chamber 3; Third, adjust the connection between the discharge end 11 and the feed end 21 through the locking mechanism 4 to form a gap that allows air bubbles to pass through while preventing material from passing through; Fourth, set the vacuum time for the vacuum chamber 3; Fifth, lock the discharge end 11 and the feed end 21 through the locking mechanism 4 to seal the connection between the discharge end 11 and the feed end 21; Sixth, under the action of the piston 8 of the first tank 1 and the second tank 2, the material in the first tank 1 enters the second tank 2 through the discharge end 11 and the feed end 21; Seventh, after the material in the second tank 2 reaches the set amount, open the vacuum chamber 3 and release the locking mechanism 4.

[0038] In the third step, the gap formed at the junction of the discharge end 11 and the feed end 21 is due to the presence of a viscous material. Since the material being transferred is extremely sticky, even with a relatively large gap, the viscous material will not move along the discharge end 11 under the negative pressure of the vacuum chamber 3 without the piston 8 of the first tank 1 pushing it. Therefore, when a vacuum is drawn at the junction of the discharge end 11 and the feed end 21, the viscous material cannot reach the gap. Thus, the gap formed at the junction of the discharge end 11 and the feed end 21 allows air bubbles to pass through, but prevents material from passing through. Furthermore, the gap can be adjusted to be appropriately small so that even if the viscous material passes through the gap, it cannot pass through it.

[0039] This viscous material transfer system employs a vacuum chamber 3 and a locking mechanism 4 to create a vacuum at the junction of the discharge end 11 and the feed end 21. During vacuuming, the locking mechanism 4 creates a gap at the junction of the discharge end 11 and the feed end 21 that allows air bubbles to pass through while preventing material from passing through. This prevents material from being extracted during vacuuming, reducing material waste and lowering production costs. Furthermore, by using the locking mechanism 4 within the vacuum chamber 3 to connect the discharge end 11 and the feed end 21, and by adjusting the tightness of the junction between the discharge end 11 and the feed end 21, the system is less prone to contaminating the material compared to using a connecting pipe to connect the discharge end 11 and the feed end 21.

[0040] Furthermore, such as Figure 3 As shown, in this embodiment, the vacuum chamber 3 includes a housing 31 and a cover 32. The housing 31 has an inlet and outlet 33, and the cover 32 is detachably installed at the inlet and outlet 33. A locking mechanism 4 is located inside the housing 31, and the vacuum port 7 is located on the housing 31 or the cover 32. Before vacuuming, the cover 32 is opened, the second tank 2 is placed inside the housing 31, and the outlet end 11 and the inlet end 21 are connected through the locking mechanism 4. Then, the cover 32 is closed. Preferably, the locking mechanism 4 is electrically controlled and electrically connected to a control module outside the vacuum chamber 3. That is, its operation is controlled by the control module outside the vacuum chamber 3, thereby adjusting the tightness of the connection between the outlet end 11 and the inlet end 21. This reduces the time that the connection between the outlet end 11 and the inlet end 21 is exposed to the outside, thus helping to reduce material contamination.

[0041] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the side wall of the housing 31 is provided with a through-hole 5, and the first tank 1 is provided with a discharge pipe 12. The discharge pipe 12 passes through the through-hole 5 and is sealed to the through-hole 5. The discharge end 11 is located at the end of the discharge pipe 12 away from the first tank 1. Thus, during docking, the first tank 1 is located outside the vacuum chamber 3, and the discharge pipe 12 passes through the through-hole 5 and extends to the locking mechanism 4 inside the vacuum chamber 3, docking with the feed end 21.

[0042] Furthermore, in this embodiment, the housing 31 is provided with a support 6 for holding the second tank 2, and the inlet / outlet 33 is larger than the second tank 2. Before vacuum feeding, the second tank 2 enters the vacuum chamber 3 through the inlet / outlet 33 and is placed on the support 6. After vacuum feeding is completed, the housing cover 32 is opened, and the second tank 2 is removed through the inlet / outlet 33.

[0043] Furthermore, in this embodiment, both the support base 6 and the locking mechanism 4 are located at the bottom of the housing 31, and the inlet / outlet 33 is located at the top of the housing 31. The placement of the support base 6 and the locking mechanism 4 at the bottom of the housing 31 facilitates installation and improves the stability of placement and docking.

[0044] Furthermore, such as Figure 5 As shown, in this embodiment, the through-hole 5 is a U-shaped opening facing upwards. A sealing plate 51 is provided above the discharge pipe 12 at the through-hole 5, and the sealing plate 51 is clamped between the discharge pipe 12 and the box cover 32. The process of engaging the discharge pipe 12 and the through-hole 5 is as follows: First, open the box cover 32 and remove the sealing plate 51, then insert the discharge pipe 12 into the through-hole 5; next, insert the sealing plate 51 from top to bottom into the through-hole 5 and press it onto the discharge pipe 12; then, close the box cover 32, so that the box cover 32 presses the sealing plate 51 tightly, thereby clamping the sealing plate 51 between the discharge pipe 12 and the box cover 32. Preferably, the two sides of the sealing plate 51 are sealed and abutted against the two sides of the through-hole 5 by sealing strips, and sealing gaskets are provided at the bottom of the through-hole 5 and on the opposite side of the sealing plate 51, clamping it onto the discharge pipe 12.

[0045] Furthermore, such as Figure 6 and Figure 7 As shown, in this embodiment, the locking mechanism 4 includes a fixed base 41, a first hoop 42, a second hoop 43, and a locking drive 44. The fixed base 41 is disposed inside the vacuum chamber 3. The first hoop 42 and the second hoop 43 are disposed opposite each other on the fixed base 41 to clamp the discharge end 11 and the feed end 21. The locking drive 44 is used to drive the first hoop 42 and the second hoop 43 to open and close. The locking drive 44 drives the first hoop 42 and the second hoop 43 to open and close, adjusting the tightness of the connection between the discharge end 11 and the feed end 21. Preferably, the locking drive 44 is an electric drive and is electrically connected to a control module outside the vacuum chamber 3. That is, the clamping degree of the first hoop 42 and the second hoop 43 is controlled by the control module outside the vacuum chamber 3, thereby adjusting the tightness of the connection between the discharge end 11 and the feed end 21.

[0046] Furthermore, in this embodiment, the first hoop 42 is fixed on the fixed base 41, and one end of the second hoop 43 is hinged to the first hoop 42, while the other end is connected to the locking drive member 44. The locking drive member 44 drives the second hoop 43 to rotate around the hinge axis, thereby realizing the opening and closing movement of the first hoop 42 and the second hoop 43 and adjusting the tightness of the connection between the first hoop 42 and the second hoop 43 and the discharge end 11 and the feed end 21.

[0047] Furthermore, in this embodiment, the locking drive 44 is a telescopic drive. The telescopic end of the telescopic drive is hinged to the other end of the second hoop 43 via a connecting rod 45. The second hoop 43 is located above the first hoop 42. The telescopic movement of the locking drive 44 drives the second hoop 43 to rotate around the hinge axis via the connecting rod 45, thereby realizing the opening and closing movement of the first hoop 42 and the second hoop 43 and adjusting the tightness of the connection between the first hoop 42 and the second hoop 43 and the discharge end 11 and the feed end 21. Preferably, the first hoop 42 has an upward-opening semi-circular shape.

[0048] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
