Description

Technical Field

[0001] This invention relates to the field of filling and sealing technology, specifically to a wound repair gel filling and sealing machine and its process. Background Technology

[0002] In the cosmetics, daily necessities, pharmaceutical, and food industries, many products are packaged in soft tubes, such as facial cleansers, toothpaste, ointments, and condiments. Fully automatic filling and sealing machines are suitable for the filling and sealing needs of plastic tubes and aluminum-plastic composite tubes in the pharmaceutical, food, cosmetic, and daily chemical industries. They can smoothly and accurately inject various pastes, ointments, and viscous fluids into the soft tubes, and complete the functions of heating and sealing the tubes, as well as printing batch numbers and production dates. Patent application number CN201811340247.2 proposes a fully automatic soft tube filling and sealing machine, including a frame, a turntable mounted on the frame, and a drive mechanism for driving the turntable to rotate on the frame. The turntable has multiple tube cups for holding the soft tubes. It also includes a feeding device, a tube loading device, a tube pressing device, a filling device, a clamping and heat-sealing device, a tail-cutting device, a tube unloading device, and a control device, all sequentially arranged on the frame. This machine can realize a fully automatic soft tube filling and sealing process, improving the automation level of soft tube filling, and resulting in high product quality and high work efficiency.

[0003] However, the current filling and sealing process for bed repair gels mainly faces the following technical bottlenecks:

[0004] 1. Significant loss of volatile components: Traditional heat sealing temperatures are high, and the localized high temperatures during sealing can exacerbate the volatilization of volatile components, which can easily affect product efficacy.

[0005] 2. Oxidative degradation of active ingredients: The ascorbic acid derivative (VC-IP) in the wound repair gel is sensitive to oxygen. Traditional filling processes have a high residual oxygen content. If oxygen is not removed from the hopper and filling tube during filling, it can easily lead to a large loss of active ingredients.

[0006] Therefore, a wound repair gel filling and sealing machine and its process are proposed to address the above problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a wound repair gel filling and sealing machine and its process to solve the aforementioned problems.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a wound repair gel filling and sealing machine, a frame, the surface of which is provided with a multi-station turntable with a tubing placement seat, and the surface of which is also sequentially provided with a tube pressing mechanism, a filling mechanism, a hot-press sealing mechanism, a tail cutting mechanism, a tube unloading mechanism and a control device;

[0009] The filling mechanism includes a filling hopper and a dispensing head that can move up and down. The outer surface of the dispensing head is fitted with a nitrogen flusher for rinsing the filling hose. During filling, the open end of the hose contacts the nitrogen flusher. The filling hopper is connected to a vacuum assembly and a nitrogen injection assembly through a pipe. A stirrer is installed inside the filling hopper.

[0010] The hot-press sealing mechanism includes a drive mechanism and two moving blocks. Hot-press plates are mounted on the surfaces of both moving blocks for hot-press sealing. Heat-buffered cooling nozzles are mounted at the bottom of both moving blocks to reduce the temperature of the wound repair gel near the hot-press plates during hot-pressing. Sealing and cooling air jets are provided on opposite sides of both moving blocks. A switching assembly is installed inside each moving block. Before and during hot-press sealing, the switching assembly is connected to the heat-buffered cooling nozzles. After hot-press sealing, the switching assembly is connected to the sealing and cooling air jets.

[0011] Preferably, the nitrogen flushing device includes an outer sheath, and a spiral air injection channel is provided between the outer sheath and the injection head. The bottom end of the spiral air injection channel is connected to an exhaust port inclined at 30°, and the top end of the spiral air injection channel is connected to an injection port. The bottom of the outer sheath has a recovery inlet, and the top has a recovery outlet.

[0012] Preferably, the nitrogen flushing device's injection port is connected to a nitrogen source via a pipe, and the nitrogen flushing device's recovery outlet is connected to a switching assembly via a delivery hose. The outer surface of the delivery hose is also fitted with a semiconductor cooler.

[0013] Preferably, the semiconductor cooler includes upper and lower housings, each housing having a cooling block inside. A semiconductor cooling chip is fixed to the surface of the cooling block, and the hot end of the semiconductor cooling chip is connected to a circulating cooling water plate. A meandering groove is formed on the surface of the cooling block.

[0014] Preferably, the hot-press sealing mechanism includes a hot-press frame, inside which a sliding rod is fixed, and the tops of the two moving blocks are slidably connected to the sliding rod, and the driving mechanism consists of two cylinders connected to the moving blocks.

[0015] Preferably, the conduction switching component includes a connecting cavity opened inside the moving block. The top of the connecting cavity is provided with an air inlet head connected to the delivery hose. The bottom of the connecting cavity is connected with a first air outlet channel and a second air outlet channel. The first air outlet channel is connected to a heat buffer cooling nozzle, and the second air outlet channel is connected to a tail-sealing cooling jet hole. The tail-sealing cooling jet hole is inclined downward at a 15° angle.

[0016] Preferably, the conduction switching assembly further includes a movable rod disposed inside the connecting cavity, the outer surface of the movable rod being connected to two plugs, a spring being fixed between one end of the movable rod and the connecting cavity, and an electromagnetic rod being disposed between the other end of the movable rod and the connecting cavity.

[0017] Preferably, the pipe pressing mechanism, filling mechanism, hot-press sealing mechanism, tail cutting mechanism, and pipe unloading mechanism are all connected to the frame via threaded adjustment brackets.

[0018] A wound repair gel filling and sealing process includes the following specific steps:

[0019] S1. The operator pours the prepared wound repair gel into the filling hopper and performs vacuum deoxygenation through the vacuum assembly.

[0020] S2. After vacuum deoxidation, nitrogen is injected through the nitrogen injection component to ensure uniform stirring by the stirring rod during deoxidation and nitrogen injection.

[0021] S3. The hose is fed into the hose placement seat by the external feeding mechanism. The hose is first pressed by the hose pressing mechanism and then moved to the bottom of the filling mechanism by the multi-station turntable.

[0022] S4. The filling head of the filling mechanism descends to make the nitrogen flusher contact the top of the hose, fills the hose with nitrogen to replace the oxygen, and injects wound repair gel into the hose through the filling head. The gas recovered after replacement is cooled by the semiconductor refrigerator and then sent to the hot-press sealing mechanism.

[0023] S5, the hot-press sealing mechanism uses gas cooled by S4 before and during hot pressing to cool the wound repair gel near the hot-press plate and reduce heat evaporation. After hot pressing, the cooled gas cools the end of the tube.

[0024] S6. After hot pressing is completed, the sealed hose is cut off by the tail-cutting mechanism and then sent out by the unloading mechanism to complete the filling and sealing.

[0025] This invention provides a wound repair gel filling and sealing machine and its process. It has the following beneficial effects:

[0026] The wound repair gel filling and sealing machine of the present invention improves upon existing filling and sealing equipment by addressing the material composition of the wound repair gel. Through the inclusion of a nitrogen flushing device and a vacuum assembly, oxygen can be removed from the filling hopper and the tubing to be filled during filling and sealing, thereby extending the retention time of the active ingredients in the wound repair gel. No modification to the delivery system is required, resulting in relatively low cost. Simultaneously, through the inclusion of a semiconductor cooler and a switching assembly, the gas inside the tubing can be recovered and cooled. This is used to reduce the temperature of the wound repair gel near the heat press plate during heat sealing, preventing excessive evaporation of volatile components due to localized overheating.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] like Figures 1-5 As shown, this embodiment of the invention provides a wound repair gel filling and sealing machine. The machine frame 1 has a multi-station turntable 2 with a tubing placement seat on its surface. The surface of the machine frame 1 also sequentially includes a tube pressing mechanism 3, a filling mechanism 4, a heat-sealing mechanism 5, a tail-cutting mechanism 6, a tube unloading mechanism 7, and a control device 8. The tube pressing mechanism 3, filling mechanism 4, heat-sealing mechanism 5, tail-cutting mechanism 6, and tube unloading mechanism 7 are all connected to the machine frame 1 via threaded adjustment brackets 11. Specifically, the threaded adjustment bracket 11 includes an adjustment frame 111, with an adjustment plate 112 slidably adjustable on its surface. An adjustment screw 113 is threadedly connected to the center of the adjustment frame 111. Rotation of the adjustment screw 113 moves the adjustment plate 112. By connecting the adjustment plate 112 on each threaded adjustment bracket 11 to each mechanism, the height of each mechanism can be adjusted to accommodate the height requirements of different tubing models. The tail-cutting mechanism 6, tube unloading mechanism 7, and tube pressing mechanism 3 are all existing technologies without modification.

[0040] The filling mechanism 4 includes a filling hopper 41 and a vertically movable dispensing head 42. Specifically, the dispensing head 42 of the filling mechanism 4 is connected to the adjusting frame 111 via a pneumatic slide table for easy downward injection of gel. The pressing head of the tube pressing mechanism 3 is also connected to the adjusting frame 111 via a pneumatic slide table for easy downward pressing. The outer surface of the dispensing head 42 is fitted with a nitrogen flusher 43 for rinsing the filling hose. During filling, the open end of the hose contacts the nitrogen flusher 43 to prevent oxygen from re-entering. The filling hopper 41 is connected to a vacuum assembly 44 and a nitrogen injection assembly 45 via pipes. The filling hopper 41 is equipped with a stirrer, which can stir the wound repair gel in the filling hopper 41 during vacuum and nitrogen injection to reduce the oxygen content in the wound repair gel and the filling hopper 41. An oxygen sensor can also be installed inside the filling hopper 41 to detect the oxygen content in real time. This method of reducing oxygen content has low equipment cost, does not require modification of the conveying system, is highly flexible, and the deoxygenation time can be adjusted at any time.

[0041] The nitrogen flusher 43 includes an outer sheath 431. A spiral gas injection channel 432 is provided between the outer sheath 431 and the dispensing head 42. The bottom end of the spiral gas injection channel 432 is connected to an exhaust port 433 at a 30° angle, which can spirally deliver nitrogen into the hose to be filled. The 30° angle can generate a swirling flow, which is more efficient than direct blowing. The top end of the spiral gas injection channel 432 is connected to the gas injection port 434. The bottom of the outer sheath 431 has a recovery inlet 435 and the top has a recovery outlet 436. The displaced gas enters from the recovery inlet 435, passes through the outside of the spiral gas injection channel 432, and is discharged from the recovery outlet 436 at the top. The gas injection port 434 of the nitrogen flusher 43 is connected to a nitrogen source through a pipeline to provide nitrogen.

[0042] Example 2:

[0043] like Figure 1 , Figures 5-9 As shown, during heat sealing, because the wound repair gel contains highly volatile substances that generate heat, heat is transferred to the wound repair gel near the heating element, resulting in relatively high evaporation at that location. To reduce evaporation, improvements are made to the existing design:

[0044] The hot-press sealing mechanism 5 includes a drive mechanism 51 and two moving blocks 52. Hot-press plates 53 are mounted on the surfaces of both moving blocks 52 for hot-press sealing. Specifically, the hot-press sealing mechanism 5 includes a hot-press frame 56, with a sliding rod 57 fixed inside. The tops of the two moving blocks 52 are slidably connected to the sliding rod 57. The drive mechanism 51 consists of two cylinders connected to the moving blocks 52. The extension and retraction of the cylinders can drive the two moving blocks 52 and the hot-press plates 53 to move and achieve hot pressing. Each of the two movable blocks 52 is equipped with a heat buffer cooling nozzle 58 at its bottom end, which is used to reduce the temperature of the wound repair gel near the heat pressure plate 53 during heat pressing. Each of the two movable blocks 52 has a sealing and cooling air jet hole 54 on its corresponding side. Each of the two movable blocks 52 has a conduction switching component 55 inside. When the hose is before and during heat pressing and sealing, the conduction switching component 55 is connected to the heat buffer cooling nozzle 58. After the hose is heat pressed and sealed, the conduction switching component 55 is connected to the sealing and cooling air jet hole 54.

[0045] The recovery outlet 436 of the nitrogen flushing device 43 is connected to the conduction switching component 55 through the delivery hose 9. The outer surface of the delivery hose 9 is also fitted with a semiconductor cooler 10, which can reuse the gas recovered from the recovery outlet 436 of the nitrogen flushing device 43 in Example 1. In order to ensure the gas cooling effect, the gas can be cooled by the semiconductor cooler 10, so that the gas can be cooled to 10-15 degrees Celsius. The low temperature inhibits volatilization. Since multiple mechanisms operate simultaneously to operate multiple hoses during filling and sealing, the hot-press sealing mechanism 5 is also in operation when the filling mechanism 4 is filling, so that the gas recovered by nitrogen flushing can be supplied to the hot-press sealing mechanism 5. The specific time control parameters can be set according to actual needs. When the hot-press plate 53 is hot-pressing, cooling gas is sprayed near the wound repair gel to form a buffer zone, so as to prevent the volatile materials inside the wound repair gel from volatilizing to a large extent when heated.

[0046] The thermoelectric cooler 10 includes upper and lower housings 1001. Each housing 1001 has a cooling block 1002 inside. A thermoelectric cooler 1003 is fixed on the surface of the cooling block 1002. The hot end of the thermoelectric cooler 1003 is connected to a circulating cooling water plate 1004. The circulating cooling water plate 1004 is connected to an external circulating pump and cooling water to improve the cooling effect of the thermoelectric cooler 1003. A meandering groove 1005 is formed on the surface of the cooling block 1002, which can increase the residence time of gas inside the thermoelectric cooler 10, thereby improving the cooling effect of the gas.

[0047] The switching assembly 55 includes a connecting cavity 551 inside the movable block 52. An air inlet 553 connected to the delivery hose 9 is located at the top of the connecting cavity 551. A first air outlet channel 554 and a second air outlet channel 555 are connected to the bottom of the connecting cavity 551. The first air outlet channel 554 is connected to a heat buffer cooling nozzle 58, and the second air outlet channel 555 communicates with a sealing cooling jet hole 54. The sealing cooling jet hole 54 is inclined downwards at a 15° angle. The switching assembly 55 also includes a movable rod 556 inside the connecting cavity 551. Two plugs 557 are connected to the outer surface of the movable rod 556. A spring 558 is fixed between one end of the movable rod 556 and the connecting cavity 551, and an electromagnetic rod 552 is provided between the other end of the movable rod 556 and the connecting cavity 551. Specifically, when the two movable blocks 52 move closer together to make the heat-pressing plate 53 contact the hose for sealing, such as... Figure 7 In the state shown, the air inlet 553 is connected to the first air outlet channel 554. Cooled gas is sent into the thermal buffer cooling nozzle 58 and sprayed out to cool the area below the seal, forming a buffer zone. After the sealing is completed, the cylinder retracts, and the solenoid rod 552 is energized. The air inlet 553 is then connected to the second air outlet channel 555. At this time, cold air is sprayed out from the sealing cooling jet hole 54 (as shown). Figure 8 This process cools the sealing area. The cooling jet vent 54 is angled downwards at 15° to ensure it reaches the sealing position precisely. When the hose moves below the hot-press sealing mechanism 5, the sealing operation is delayed by 3-5 seconds. During this delay, the gas recovered from the previous process is cooled and then sprayed out to cool the hose inlet, providing pre-cooling to counteract the heat radiation generated by the hot-press plate 53 on the gel during heating. This keeps the gel surface temperature below 35 degrees Celsius, reducing the evaporation loss rate.

[0048] Example 3:

[0049] A wound repair gel filling and sealing process includes the following specific steps:

[0050] S1. The operator pours the prepared wound repair gel into the filling hopper 41 and performs vacuum deoxygenation using the vacuum assembly 44. The prepared wound repair gel is composed of purified water, carbomer, ascorbate tetraisopalmitate, dimethicone, decamethylcyclopentasiloxane, glycerin, triethanolamine, polysorbate 80, parabens, and N,2,3-trimethyl-2-isopropylbutyramide. The fat-soluble vitamin C derivative, a potent antioxidant, inhibits melanin production, promotes collagen synthesis, and improves pigmented scars. Attention should be paid to the effect of oxygen on this substance. The low flash point (76°C) of decamethylcyclopentasiloxane (D5) makes it easily vaporized at high heat-sealing temperatures; the cooling agent N,2,3-trimethyl-2-isopropylbutyramide easily sublimates at temperatures above 150°C, while heat-sealing temperatures are generally between 170-200°C. The vacuum assembly 44 includes a vacuum pump, vacuum sensor, vacuum tubing, and valves.

[0051] S2. After vacuum deoxygenation, nitrogen is injected through the nitrogen injection assembly 45. During deoxygenation and nitrogen injection, the stirring rod ensures uniform stirring. The nitrogen injection assembly 45 includes a nitrogen source, flow controller and pipeline, and gas distributor. During deoxygenation, the process is controlled by PLC programming. The first vacuuming is performed by starting the vacuum pump and evacuating to 50 kPa. The first nitrogen filling is then performed by shutting off the vacuum pump and filling with nitrogen to atmospheric pressure or a slightly positive pressure (1.05 atm). The second vacuuming is repeated to 50 kPa to further reduce residual oxygen. The second nitrogen filling is then performed to the target pressure (1.3 atm).

[0052] S3. The hose is fed into the hose placement seat by the external feeding mechanism. The hose is first pressed by the hose pressing mechanism 3 and then moved to the bottom of the filling mechanism 4 by the multi-station turntable 2.

[0053] S4. The dispensing head 42 of the filling mechanism 4 descends to make the nitrogen flusher 43 contact the top of the hose, and nitrogen is filled into the hose to replace the oxygen. The wound repair gel is injected into the hose through the dispensing head 42. The gas recovered after replacement is cooled by the semiconductor cooler 10 and then sent to the hot pressing sealing mechanism 5.

[0054] S5, the hot-press sealing mechanism 5, before and during hot pressing, uses gas cooled by S4 to cool the wound repair gel near the hot-press plate 53 to reduce heat evaporation. After hot pressing, the cooled gas cools the tube sealing area.

[0055] S6. After hot pressing is completed, the sealed hose is cut off by the tail-cutting mechanism 6 and then sent out by the unloading mechanism 7 to complete the filling and sealing.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
