Abstract

This invention discloses a hydraulic silicone two-component injection molding machine, belonging to the field of injection molding machine technology. It includes a frame and a hydraulic feeding unit. Each hydraulic feeding unit includes a pressure plate mounted on the upper surface of the frame. A recycling mechanism for waste silicone is provided on one side of the upper surface of the pressure plate. The recycling mechanism includes a receiving screw tube that is threadedly connected to the inside of the pressure plate. The receiving screw tube is fixedly connected to a collection tank via a drain pipe. The collection tank has a sealing mechanism inside for sealing the drain pipe. An alarm mechanism for venting is provided on the top of the collection tank. By setting up the recycling mechanism, sealing mechanism, and alarm mechanism, under the pressure of the pressure plate, the jet of air inside the tank impacts the plastic ball through the flow pipe, causing it to bounce and collide, producing a continuous sound, thus forming a clear venting signal. When the gas is completely vented and liquid flows in, the jet disappears, the plastic ball immediately stops, and the sound abruptly ceases. This objective physical signal replaces manual visual experience, enabling the operator to accurately determine that venting is complete.

Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, and more specifically, to a hydraulic silicone two-component injection molding machine. Background Technology

[0002] The core of two-component liquid silicone injection molding technology lies in mixing two liquid components, A and B, in a precise ratio and then thermosetting them in a mold. The accuracy of the mixing ratio and the removal of air bubbles in the material directly determine the mechanical properties, appearance quality, and yield of the product. Therefore, it places stringent requirements on the metering stability and degassing capability of the injection molding machine.

[0003] Currently, a typical hydraulic silicone two-component injection molding machine usually adopts the following operating procedure: First, components A and B are stored in separate material tanks. Initial venting is performed through a manual pressure plate feeding system. The operator presses down the pressure plate and observes the vent holes, closing the valves based on experience the moment the silicone overflows to remove air from the tanks. Subsequently, the material is metered by a hydraulically driven plunger or gear pump and transported to a static mixer for mixing. Finally, the mixed silicone is injected into the mold by the hydraulic injection unit. In this process, the venting, metering, and mixing stages are performed independently, relying on manual intervention and time control.

[0004] During the process of venting the material tank, traditional manual venting relies entirely on the operator's experience, which can easily lead to incomplete venting of air bubbles or waste of adhesive due to misjudgment. Furthermore, the overflow of adhesive when the pressure plate valve is closed can contaminate the equipment and form solidified residue. Summary of the Invention

[0013] As a further aspect of the present invention: the recycling mechanism further includes a discharge pipe disposed on both sides of the outer surface of the discharge pipe, the top of the discharge pipe being fixedly connected to the collection spherical tank, and the bottom of the collection spherical tank having a discharge port corresponding to the discharge pipe; the bottom of the discharge pipe is threadedly connected to a collection tank; and the outer circumference of the collection spherical tank is provided with support rods fixedly connected to the frame on both sides.

[0014] As a further aspect of the present invention: connecting rods are fixedly connected to both sides of the outer circular surface of the first screw seat, and a blocking ball is fixedly connected to the first screw seat through the connecting rods. The outer diameter of the blocking ball is the same as the inner diameter of the feed port.

[0015] As a further aspect of the present invention: a set of symmetrical arc-shaped baffles are fixedly connected to the upper surface of the frame; a centering mechanism for cooperating with the arc-shaped baffles is provided on both the front and rear sides of the frame; the centering mechanism includes a U-shaped frame fixedly connected to the front side of the frame; a bearing rod is rotatably connected inside the U-shaped frame; one end of the bearing rod passes through the U-shaped frame and is fixedly connected to a driven bevel gear; an L-shaped support seat for supporting the bearing rod is fixedly connected to the bottom of the frame; a fixing sleeve fixedly connected to the bearing rod is provided in the middle of the U-shaped frame; a support plate is fixedly connected to one side of the outer circular surface of the fixing sleeve; a pad is fixedly connected to one side of the support plate; a side baffle is fixedly connected to the upper surface of the support plate near the pad; and a drive assembly for driving the driven bevel gear is provided on both the front and rear sides of the frame.

[0017] As a further aspect of the present invention: an electric telescopic rod arranged in a linear pattern is fixedly connected to the bottom of the support plate, and a universal wheel is fixedly installed at one end of the electric telescopic rod; an airbag is fixedly installed on one side of the side baffle, and an electric air pump is fixedly installed on the other side, and an inflation tube for supplying air to the airbag is fixedly connected to the output end of the electric air pump.

[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0019] (1) This solution sets up a recycling mechanism, a sealing mechanism and an alarm mechanism. Under the pressure of the pressure plate, the jet of air in the barrel impacts the plastic ball through the flow pipe, causing it to bounce and collide to produce a continuous sound, forming a clear exhaust signal. When the gas is exhausted and the liquid flows in, the jet disappears, the plastic ball immediately stops, and the sound stops abruptly. This objective physical signal replaces manual visual experience, enabling the operator to accurately judge that the exhaust is complete. Subsequently, the sealing mechanism is immediately triggered, driving the sealing plate to quickly block the discharge pipe, realizing the seamless switching from exhaust to feeding, eliminating the overflow and waste of adhesive during the switching stage. At the same time, all the small amount of splashed adhesive that may escape with the gas during the entire process is completely collected by the pre-set collection ball tank, preventing equipment contamination from the source.

[0020] (2) By setting a sealing mechanism, when the exhaust is completed, the servo motor starts, which drives the drive rod to rotate the main gear and uses the gear to drive the coaxial bidirectional threaded rod to rotate, so that the No. 2 spiral seat moves straight down in the limit frame. Then, the receiving rod pushes the sealing plate to press it firmly against the sealing surface of the drain pipe port, forming a reliable seal. This process replaces manual valve closing with electric drive, which is much faster than manual operation. It completely eliminates the window period of glue overflow caused by action delay. At the same time, the reverse rotation can accurately lift the sealing plate to open the channel and prepare for the next exhaust, ensuring the timeliness, consistency and reliability of the sealing action. It fundamentally solves the problem of material waste and equipment pollution caused by untimely closing.

[0021] (3) By setting up a sealing mechanism and an alarm mechanism, during the exhaust stage, the high-speed airflow blows the plastic ball up to produce an impact sound, and on the other hand, it flows through the throat of the cone bucket to generate negative pressure, which drives the components composed of the moving ball, the cone bucket and the ring plate to vibrate and collide. This, together with the initial collision sound of the plastic ball and the flow tank, forms a dual, complementary and synchronous auditory alarm, thereby enhancing the recognition and reliability of the signal in a noisy environment. When the gas is exhausted, the two sounds stop at the same time, thus providing the operator with a clearer objective judgment basis. Attached Figure Description

[0039] The hydraulic silicone two-component injection molding machine provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0040] like Figures 1 to 7 As shown, this embodiment of the invention provides a hydraulic silicone two-component injection molding machine, including a frame 1 and a control panel 2 mounted on the frame 1; hydraulic feeding units are provided on both sides of the upper surface of the frame 1, each hydraulic feeding unit including a pressure plate 3 mounted on the upper surface of the frame 1, with a sealing ring on its edge; a lifting drive assembly for driving the pressure plate 3 to rise and fall is fixedly installed in the middle of the upper surface of the frame 1; a pump screw 4 is installed in the middle of the top of the pressure plate 3, and a main hydraulic cylinder 5 is drivenly connected to the upper end of the pump screw 4 to transmit the linear driving force of the main hydraulic cylinder 5 to the pressure plate 3; a main pump motor 6 is hydraulically connected to the top of the main hydraulic cylinder 5 to provide power to it; a recycling mechanism 9 for recycling waste glue is provided on one side of the upper surface of the pressure plate 3;

[0041] The recycling mechanism 9 includes a receiving screw tube 93 that is threadedly connected to the inside of the pressure plate 3. The top of the receiving screw tube 93 is fixedly connected to a drain pipe 92. The top of the drain pipe 92 is fixedly connected to a collection ball tank 91. The inside of the collection ball tank 91 is provided with a sealing mechanism 10 for sealing the drain pipe 92. The top of the collection ball tank 91 is provided with an alarm mechanism 11 for exhaust response. The alarm mechanism 11 includes a flow pipe 112 that is fixedly connected to the top of the inside of the collection ball tank 91. The bottom of the flow pipe 112 is fixedly connected to a filter plate 114. The top of the flow pipe 112 is fixedly connected to the flow tank 111. A plastic ball 115 is placed on the upper surface of the filter plate 114.

[0042] To address the problems of traditional manual venting relying on operator experience and judgment, which can easily lead to incomplete air removal, waste of adhesive, and equipment contamination, the above-mentioned technical solution is adopted. This solution mainly consists of a recovery mechanism 9, a sealing mechanism 10, and an alarm mechanism 11. In operation, the raw material barrel is first placed directly below the pressure plate 3. Then, the main hydraulic cylinder 5 and the pump screw 4 are activated. Under their combined drive, the pressure plate 3 is pressed into the raw material barrel, compressing the air inside. The air first enters the receiving screw 93 of the recovery mechanism 9 through the internal channel of the pressure plate 3. Subsequently, the airflow rises sequentially through the discharge pipe 92 into the collection tank 91. In the initial stage of venting, the high-speed airflow continues upward and is ejected through the flow pipe 112 of the alarm mechanism 11. This airflow directly acts on the plastic balls 115 placed on the filter plate 114, blowing them up and causing them to continuously bounce within a confined space. The collision produces a clearly audible sound, which serves as a clear physical auditory signal, objectively indicating that the system is in the "venting" state. As the pressure plate 3 continues to press down, the air in the barrel is exhausted, and the adhesive begins to enter the channel. Since the liquid flow rate and power are much lower than those of the gas, they can no longer support the bouncing of the plastic ball 115, and the plastic ball 115 immediately falls back to the filter plate 114 and comes to a stop. All abnormal sounds suddenly stop, thus providing the operator with an intuitive basis for judging that "the gas has been exhausted". Based on this judgment, the operator can control the start of the sealing mechanism 10 to promptly block the top opening of the discharge pipe 92, switching the venting stage to the closed feeding stage, effectively preventing the pure adhesive from overflowing during the switching process. During the entire venting and switching process, any trace amount of splashed adhesive that may be carried out with the gas is contained in the collection tank 91, avoiding contamination of the surface of the pressure plate 3 and the surrounding environment.

[0043] like Figures 1 to 7 As shown, the lifting drive assembly includes a dual-axis linear motor 7 fixedly installed in the middle of the upper surface of the frame 1, and hydraulic rods 8 located on both sides of the outer circular surface of the pressure plate 3. The upper end of the hydraulic rod 8 is fixedly connected to the housing of the main hydraulic cylinder 5, and the lower end is fixedly connected to the frame 1. The main hydraulic cylinder 5 provides lifting guidance for the pressure plate 3.

[0044] When the height of the feeding unit needs to be adjusted to accommodate the new raw material barrel, the dual-axis linear motor 7 starts, driving the main hydraulic cylinder 5 housing and the entire pressure plate 3 assembly to perform vertical lifting and lowering movements. During this process, the hydraulic rods 8 symmetrically distributed on both sides of the pressure plate 3 play a crucial role: their upper ends are fixed to the main hydraulic cylinder 5 housing, and their lower ends are connected to the frame 1, forming a rigid auxiliary guide and support frame. This effectively constrains the radial sway of the main hydraulic cylinder 5 and the pressure plate 3 during the lifting and lowering process, ensuring the straightness of the movement path and the overall stability. As a result, the pressure plate 3 can always be accurately and vertically aligned with the opening of the raw material barrel. The symmetrically arranged hydraulic rods 8 and the main hydraulic cylinder 5 housing form a linkage support structure that provides reliable guidance and resistance to lateral forces throughout the process, ensuring that the pressure plate 3 and the raw material barrel remain concentric. This allows the sealing rings on the edge of the pressure plate 3 to be pressed into the barrel opening evenly and reliably. In the above operation, not only is the height of the feeding unit quickly and automatically adjusted, solving the problem of equipment adaptability to raw material barrels of different specifications, but it also lays a structural foundation for the subsequent formation of an effective sealing space, efficient exhaust, and stable feeding, avoiding air leakage, glue leakage, or abnormal wear of the sealing rings that may be caused by misalignment.

[0045] like Figures 1 to 7 As shown, the sealing mechanism 10 includes a bidirectional threaded rod 104 located in the middle of the interior of the spherical tank 91. Both ends of the bidirectional threaded rod 104 are provided with limiting frames 105 fixedly connected to the inner wall of the spherical tank 91. The front side of the bidirectional threaded rod 104 is provided with a limiting frame 108 fixedly connected to the limiting frame 105. A spacer 106 is fixedly connected to the middle of the bidirectional threaded rod 104. The upper and lower sides of the spacer 106 are respectively provided with a first screw seat 109 and a second screw seat 1012 threadedly connected to the bidirectional threaded rod 104. One side of the outer circular surface of the first screw seat 109 and the second screw seat 1012 is provided with a slider that is slidably connected to the limiting frame 108. The two sides of the bottom of the second screw seat 1012 are fixedly connected with receiving rods 1013. The second screw seat 1012 is fixedly connected to a sealing plate 1014 through the receiving rods 1013. An adjustment component for driving the bidirectional threaded rod 104 to rotate is also provided on one side of the top of the spherical tank 91.

[0046] like Figures 1 to 7 As shown, the adjustment assembly includes a driven gear 107 fixedly connected to the top of the outer surface of the bidirectional threaded rod 104, a servo motor 101 fixedly connected to the top of the outer surface of the spherical container 91, a drive rod 102 fixedly connected to the output end of the servo motor 101, and a main gear 103 fixedly connected to one end of the drive rod 102 through the spherical container 91. The main gear 103 meshes with the driven gear 107.

[0047] To address the problem of traditional manual venting relying on manual timing when closing valves, which can easily lead to spillage of adhesive from the venting channel due to delayed or slow closure, resulting in material waste and equipment contamination, a new system is implemented where the operator immediately activates the servo motor 101 after the alarm mechanism 11 signals that the gas has been completely vented. The output shaft of the servo motor 101 drives the drive rod 102 and the main gear 103 fixed to its end to rotate. The main gear 103 drives the driven gear 107 meshing with it to rotate, thereby rotating the bidirectional threaded rod 104 coaxially fixed to the driven gear 107. During the rotation of the bidirectional threaded rod 104, the first and second screw seats 109 and 1012, screwed onto it, move synchronously in opposite or opposite directions along the bidirectional threaded rod 104 under the constraint of the limit frame 108. When it is necessary to close the channel, the servo motor 101 drives the bidirectional threaded rod 104 in reverse, causing the first and second screw seats 109 and 1012 to... When the two spiral seats move in opposite directions, the second spiral seat 1012 pushes the sealing plate 1014 downward through the receiving rod 1013 fixed to its bottom, until the sealing plate 1014 tightly seals the top outlet of the discharge pipe 92 below it, thereby quickly cutting off the exhaust and overflow passages. Conversely, when it is necessary to exhaust the material in the raw material barrel in the initial stage, simply start the servo motor 101 to drive the bidirectional threaded rod 104 to rotate forward, so that the first spiral seat 109 and the second spiral seat 1012 move in opposite directions. At this time, the sealing plate 1014 moves upward, opening the top outlet of the discharge pipe 92, and normal exhaust operation can be performed, which is simple and fast.

[0048] like Figures 1 to 7 As shown, the alarm mechanism 11 also includes a retainer 116 fixedly connected to the top of the circulation tank 111. The inside of the retainer 116 is hemispherical and hollow. A movable ball 117 is rotatably connected inside the retainer 116. A conical hopper 118 is fixedly connected to the bottom of the movable ball 117. An annular plate 119 is provided directly below the conical hopper 118. Fixing plates 1110 fixedly connected to the circulation tank 111 are provided on both sides of the outer surface of the annular plate 119. An exhaust port 113 is provided on the top of the circulation tank 111. The inner diameter of the exhaust port 113 is smaller than the outer diameter of the plastic ball 115.

[0049] like Figures 1 to 7 As shown, the recycling mechanism 9 also includes a discharge pipe 96 located on both sides of the outer surface of the discharge pipe 92. The top of the discharge pipe 96 is fixedly connected to the collection spherical tank 91, and the bottom of the collection spherical tank 91 is provided with a discharge port 95 corresponding to the discharge pipe 96. The bottom of the discharge pipe 96 is threadedly connected to a collection tank 97. Support rods 94 fixedly connected to the frame 1 are provided on both sides of the outer circular surface of the collection spherical tank 91.

[0050] like Figures 1 to 7As shown, connecting rods 1010 are fixedly connected to both sides of the outer circular surface of the first screw seat 109. A blocking ball 1011 is fixedly connected to the first screw seat 109 through the connecting rods 1010. The outer diameter of the blocking ball 1011 is the same as the inner diameter of the discharge port 95.

[0051] To address the issues of subjective errors in traditional exhaust operations due to reliance on human experience to determine the exhaust endpoint, the susceptibility of relying solely on auditory signals to interference in noisy environments, and the difficulty in cleaning up spilled adhesive contamination of equipment, a high-speed airflow is introduced at the initial stage of exhaust. This airflow rushes out from the flow pipe 112 and enters the flow tank 111. The airflow first blows up the plastic ball 115 placed on the filter plate 114. Since the diameter of the exhaust port 113 is smaller than the diameter of the plastic ball 115, the plastic ball 115 is effectively confined within the flow tank 111. Under the action of the airflow, it bounces violently and impacts the tank wall and the filter plate 114, producing a continuous and crisp collision sound. As the high-speed airflow continues upward, it passes through the throat of the cone 118 suspended below the sleeve 116, where the flow velocity suddenly increases, creating a local negative pressure. This negative pressure acts on the movable ball 117, which is fixedly connected to the cone 118, causing it to rotate and vibrate slightly within the sleeve 116. This causes the entire cone 118 assembly to vibrate at high frequency. The bottom edge of the vibrating cone 118 intermittently collides with the annular plate 119 fixed directly below it, producing a sharp sound. The simultaneous sound of two sounds with different qualities and frequencies creates a dual, complementary auditory alarm. When the gas in the container is exhausted and the adhesive begins to enter, the airflow disappears instantly. The plastic ball 115 immediately falls back to the filter plate 114 and comes to a stop, and the collision sound ceases. At the same time, the cone 118 assembly loses its drive, and the vibration and whistling sounds disappear synchronously. The "synchronous start and stop" of the two sounds provides the operator with a very clear and interference-resistant signal that the exhaust is complete. Any adhesive that may overflow during the venting and subsequent sealing processes is collected by the collection tank 91 and temporarily stored in the threadedly detachable collection tank 97 via the discharge port 95 and discharge pipe 96, achieving centralized management of waste. When the collection tank 91 needs to be cleaned periodically, the servo motor 101 is activated to drive the second screw seat 1012 downward, which in turn drives the sealing plate 1014 to block the discharge pipe 92 via the receiving rod 1013. On the other hand, the first screw seat 109 moves upward, which drives the blocking ball 1011 to rise via the connecting rod 1010 and opens the discharge port 95. At this time, the waste collected in the collection tank 91 enters the collection tank 97 through the discharge pipe 96, facilitating the periodic treatment of waste adhesive and the normal venting of new raw materials.

[0052] like Figures 1 to 7As shown, a set of symmetrical arc-shaped baffles 14 are fixedly connected to the upper surface of the frame 1. The front and rear sides of the frame 1 are provided with centering mechanisms 12 that cooperate with the arc-shaped baffles 14. The centering mechanism 12 includes a U-shaped frame 121 fixedly connected to the front side of the frame 1. A bearing rod 122 is rotatably connected inside the U-shaped frame 121. One end of the bearing rod 122 passes through the U-shaped frame 121 and is fixedly connected to a driven bevel gear 124. An L-shaped support seat 123 for supporting the bearing rod 122 is fixedly connected to the bottom of the frame 1. A fixing sleeve 125 fixedly connected to the bearing rod 122 is provided in the middle of the U-shaped frame 121.

[0053] like Figures 1 to 7 As shown, the drive assembly 13 includes a dual-drive shaft motor 131 fixedly connected to the front and rear sides of the frame 1. Both output ends of the dual-drive shaft motor 131 are fixedly connected to a rotating rod 132. One end of the rotating rod 132 is fixedly connected to a main bevel gear 134, and an auxiliary frame 133 fixedly connected to the frame 1 is provided on the side of the rotating rod 132 near the main bevel gear 134.

[0054] like Figures 1 to 7 As shown, the bottom of the support plate 126 is fixedly connected to an electric telescopic rod 15 arranged in a linear pattern, and one end of the electric telescopic rod 15 is fixedly installed with a caster wheel 16; an airbag 129 is fixedly installed on one side of the side baffle 128, and an electric air pump 1210 is fixedly installed on the other side, and the output end of the electric air pump 1210 is fixedly connected to an inflation tube 1211 for supplying air to the airbag 129.

[0055] To address the issues of low efficiency, poor positioning accuracy, and the risk of damage or displacement caused by heavy material containers colliding rigidly with the equipment during material container replacement in hydraulic two-component silicone injection molding machines, the operator pushes the material container into the working area on the frame 1. The outer wall of the material container first contacts two sets of symmetrical arc-shaped baffles 14, completing coarse positioning under the guidance of the arc surfaces, so that the container is roughly located directly below the pressure plate 3. Then, the dual-drive shaft motor 131 is started, driving the two rotating rods 132 and their ends. The main bevel gear 134 rotates, causing the driven bevel gear 124, which meshes with it, to rotate, converting the rotational motion of the horizontal axis into a vertical rotational motion. This causes the support rod 122 to rotate under the support of the U-shaped frame 121 and the L-shaped support base 123, driving the fixed sleeve 125, support plate 126, pad 127, and side baffle 128 to synchronously approach from the side of the raw material barrel. When the pad 127 contacts one side of the raw material barrel, the electric air pump 1210 starts, inflating the air bladder 129 through the inflation pipe 1211, causing the air bladder to expand. The inflatable bladder 129 applies uniform, flexible pressure from the other side of the raw material barrel, working in conjunction with the pad 127 to gently yet firmly clamp the barrel and correct its final position, ensuring precise alignment between the barrel opening center and the axis of the pressure plate 3. After centering and clamping, the electric telescopic rod 15 at the bottom of the support plate 126 extends, pushing the caster wheel 16 to the ground to support the entire support plate 126. Subsequently, the drive assembly 13 can work in reverse, driving the entire support plate 126 to move outward, using the rolling of the caster wheel 16 to move the raw material barrel out from under the pressure plate 3. The area provides space for the pressing of the pressure plate 3 and subsequent operations. After the operation is completed, the mechanism can be reset in reverse order to prepare for the next operation. During this operation, not only is the automation and high-precision centering of the raw material barrel achieved, solving the problems of low efficiency, poor repeatability and high labor intensity of manual positioning, but also, combined with the flexible clamping of the airbag 129, it provides a large area of ​​uniform clamping force, avoiding excessive local pressure caused by point contact or line contact, effectively protecting the integrity of the raw material barrel, especially the plastic barrel, and preventing the sealing from being affected by barrel deformation.

[0056] In use, the operator first pushes the raw material barrel into the working area on the frame 1. The barrel wall is roughly positioned by the symmetrical arc-shaped baffles 14. Then, the dual-drive shaft motor 131 is started, and the main bevel gear 134 and the driven bevel gear 124 drive the support rod 122 to rotate, so that the support plate 126 and the pad 127 approach the barrel from the side. Next, the electric air pump 1210 is started to inflate the air bag 129, so that it cooperates with the pad 127 to flexibly clamp the raw material barrel and accurately position it directly under the pressure plate 3. After centering, the electric telescopic rod 15 extends so that the casters 16 touch the ground, providing bottom support for the entire support plate 126 and the centered raw material barrel. Then, to adapt to different barrel heights, the dual-drive shaft motor 131 is started. A linear motor 7 drives the housing of the main hydraulic cylinder 5 and the entire feeding unit to rise and fall smoothly. Guided by the hydraulic rod 8, the pressure plate 3 is precisely aligned with the barrel opening. Then, the main pump motor 6 drives the main hydraulic cylinder 5, which pushes the pressure plate 3 down through the pump screw 4. After the air in the barrel is compressed, it flows through the internal channel of the pressure plate 3, the receiving screw tube 93, and the discharge pipe 92 in sequence, and enters the ball collection tank 91. Finally, it is sprayed into the circulation tank 111 of the alarm mechanism 11 through the circulation pipe 112. In the initial stage of exhaust, the high-speed airflow blows up the plastic balls 115 on the filter plate 114, causing them to collide and make a sound. On the other hand, it flows through the throat of the cone hopper 118 to generate negative pressure, attracting the moving ball 117 and causing the cone hopper 118 to vibrate, causing its edge to hit the annular plate 119 and make a whistling sound. These complementary auditory signals clearly indicate that venting is in progress. When the gas is completely exhausted and the adhesive flows in, the airflow disappears, and both sounds stop abruptly, providing a clear venting signal. Subsequently, based on the venting signal, the operator starts the servo motor 101 of the sealing mechanism 10, which drives the bidirectional threaded rod 104 to rotate forward via gear transmission. This causes the second screw seat 1012 to move the sealing plate 1014 downward, blocking the outlet at the top of the discharge pipe 92, cutting off the venting passage, and the system enters a closed feeding state. At this time, the first screw seat 109 moves upward along the limit frame 108 and opens the discharge port. 95, so that the glue initially carried out by the exhaust flows from the collection tank 91 into the collection tank 97, and is thus uniformly collected in the collection tank 91 for subsequent processing; when the servo motor 101 drives the bidirectional threaded rod 104 to reverse through gear transmission, the second screw seat 1012 drives the sealing plate 1014 to move upward, and the exhaust channel is opened; at the same time, the first screw seat 109 uses the connecting rod 1010 to block the discharge port with the blocking ball 1011, thereby ensuring that the waste glue carried out during subsequent gas exhaust is uniformly collected in the collection tank 91 to avoid waste liquid splashing.
