Description

Technical Field

[0001] This utility model relates to the field of low modulus adhesive production technology, and in particular to a vacuum stirring and degassing machine for low modulus adhesive production. Background Technology

[0002] A vacuum mixing and degassing machine is a device specifically designed for mixing and degassing liquid or colloidal materials. It removes air bubbles or air from the material by mixing in a vacuum environment, thereby ensuring the uniformity and high quality of the final product. Its main function is to mix liquid materials evenly and remove air bubbles in the process.

[0003] When degassing low-modulus adhesives, the adhesive is placed inside a rotating drum, which is then fixed on a rotating frame. Finally, the machine cover is closed, secured by spring clips on the degassing machine body. The drive motor inside the degassing machine body is then started, driving the rotating frame to rotate at high speed via a coupling. This causes the rotating drum to move synchronously, utilizing centrifugal force to create radial flow of the adhesive. Combined with the vacuum environment inside the degassing machine body, this achieves the separation and removal of air bubbles. Due to the pseudoplasticity of low-modulus adhesives, shear thinning occurs during the degassing process due to centrifugal force. The material flow rate is uneven between the drum wall and the central area, creating a shear gradient difference. This causes air bubbles to be encased by adhesive layers with different flow rates during migration, making it difficult for them to overcome the viscoelastic resistance of the adhesive and accumulate on the liquid surface. Consequently, the air bubbles are difficult to separate and remove effectively. This limits the degassing effect of traditional degassing machines on low-modulus adhesives, thus affecting the quality of the final product. Utility Model Content

[0004] The technical problem this invention aims to solve is that, due to the pseudoplasticity of low-modulus adhesives, shear thinning occurs during the degassing process due to centrifugal force. This results in uneven material flow rates on the barrel wall and in the central region, creating a shear gradient difference. Consequently, bubbles are encapsulated by adhesive layers with varying flow rates during migration, making it difficult for them to overcome the viscoelastic resistance of the adhesive and accumulate on the liquid surface. This makes it difficult for bubbles to be effectively separated and discharged, thus limiting the degassing effect of traditional degassing machines on low-modulus adhesives and consequently affecting the quality of the final product.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a vacuum mixing and degassing machine for producing low-modulus adhesive, including a degassing machine body and a rotating drum. A rotating frame is rotatably installed on the inner wall of the degassing machine body, and the rotating drum is inserted into the inner wall of the rotating frame. A machine cover is detachably installed on the inner wall of the degassing machine body by means of a spring buckle. An auxiliary device is provided on one side of the machine cover. The auxiliary device can drive the drive mechanism to move by rotating the rotating frame, thereby driving the extrusion plate to reciprocate on the outer surface of the slide rod, extruding the degassed low-modulus adhesive inside the rotating drum, and achieving the effect of auxiliary degassing treatment.

[0006] Preferably, the auxiliary device includes a slide bar, one side of which is fixedly mounted on one side of the machine cover; an extrusion plate, the inner wall of which is slidably mounted on the outer surface of the slide bar and inserted into the inner wall of the rotating drum; two drive mechanisms, the drive mechanisms being disposed between one side of the extrusion plate and one side of the machine cover, for driving the extrusion plate to reciprocate up and down on the slide bar and within the inner wall of the rotating drum; a third spring, the inner wall of which is sleeved on the outer surface of the slide bar, and both ends being fixedly mounted on one side of the machine cover and one side of the extrusion plate, respectively; and several venting mechanisms, the venting mechanisms being disposed on one side of the extrusion plate, for venting the gas in the bubbles from one side of the extrusion plate when the extrusion plate extrudes and removes bubbles from the low-modulus adhesive inside the rotating drum.

[0007] The effect achieved by the above-mentioned components is as follows: By setting up auxiliary devices, when using the degassing machine body to degas the internal air bubbles during the production of low-modulus adhesive, the low-modulus adhesive is placed inside the rotating drum, and then the rotating drum is placed on the rotating frame and fixed. At this time, the extrusion plate on the machine cover is inserted into the rotating drum, and the machine cover is closed, with the spring clip on the degassing machine body fixing the machine cover in place. One end of the spring clip is inserted into the inner wall of the outer surface of the machine cover, while the other end is slidably installed in the inner wall of the degassing machine body, and one side is connected to the inner wall of the degassing machine body by a spring. During the degassing process, the drive motor inside the degassing machine body can be started to drive the rotating frame to rotate at high speed through the coupling, thereby driving the rotating drum. Synchronous motion utilizes centrifugal force to induce radial flow of the adhesive. This, combined with the vacuum environment inside the degassing machine, enables the separation and removal of air bubbles. As the rotating frame rotates, it drives the drive mechanism, which, along with the reset function of the third spring, causes the extrusion plate to reciprocate up and down within the slide bar and the inner wall of the rotating drum. The positive thrust generated by mechanical extrusion breaks the shear gradient formed by the centrifugal force field, forcing air bubbles in dead zones to detach from the adhesive. Simultaneously, the synergistic effect of extrusion and centrifugation creates a pulsed pressure field, causing the air bubbles to continuously expand and merge during the alternating force process. Ultimately, the bubbles rapidly escape in the vacuum environment and are then discharged through the exhaust mechanism on one side of the extrusion plate, achieving efficient degassing and improving the quality of the final product.

[0008] Preferably, the auxiliary device further includes a plurality of pins, wherein one side of the pins is fixedly mounted on the side of the compression plate away from the third spring.

[0009] The effect achieved by the above-mentioned components is that by setting pins, it helps to enhance the mechanical intervention on the glue during the degassing process, especially in the dead corner areas of the glue. The pins can effectively break the accumulation of bubbles and promote the rupture and discharge of bubbles.

[0010] Preferably, the driving mechanism includes several abutment frames, one side of which is fixedly mounted on the outer surface of the rotating frame; two U-shaped air cylinders, both ends of which are installed through the machine cover on one side; a first piston rod, one end of which is installed through the inner wall of one end of the U-shaped air cylinder, and the other end abuts against one side of the abutment frame; a first spring, the inner wall of which is sleeved on the outer surface of one end of the first piston rod, and both ends are fixedly mounted on one side of the first piston rod and one side of the inner wall of the U-shaped air cylinder, respectively; a second piston rod, one end of which is installed through the inner wall of the U-shaped air cylinder away from the first piston rod, and the other end is fixedly mounted on one side of the extrusion plate, the first piston rod and the second piston rod forming a sealed space between the U-shaped air cylinders; and a second spring, the inner wall of which is sleeved on the outer surface of one end of the second piston rod, and both ends are fixedly mounted on one side of the second piston rod and one side of the inner wall of the U-shaped air cylinder, respectively.

[0011] The effect achieved by the above components is as follows: By setting a drive mechanism, when the rotating frame rotates, it will drive several abutment frames to move in a circular motion. After rotating to a certain angle, one side of the abutment frame will abut against one side of the first piston rod, causing it to slide upward in the U-shaped air cylinder. This will stretch the first spring, squeezing the air inside the U-shaped air cylinder to one end, pushing the second piston rod to one end, causing the second spring to contract. This will push the extrusion plate to slide downward on the slide rod, squeezing the low-modulus glue inside the rotating barrel and breaking any air bubbles that have not been expelled. At this time, the third spring is in a stretched state. When the first piston rod is completely removed from the abutment frame, the first spring will drive the first piston rod to reset. At the same time, the second and third springs will also drive the second piston rod and the extrusion plate to reset respectively, preparing for subsequent extrusion. Therefore, the drive mechanism can drive the extrusion plate to move up and down reciprocally inside the rotating barrel.

[0012] Preferably, the drive mechanism further includes two rollers, wherein the rollers are rotatably mounted in the inner wall of one end of the first piston rod.

[0013] The effect achieved by the above components is that by setting rollers, the contact wear between one end of the first piston rod and the abutment frame can be reduced, making it easier to abut and push it.

[0014] Preferably, a reinforcing rod is fixedly installed on both sides of one end of the second piston rod, and one side of the reinforcing rod is fixedly installed on one side of the extrusion plate.

[0015] The effect achieved by the above-mentioned components is that by setting a reinforcing rod, the connection area between one end of the second piston rod and the extrusion plate can be increased, making the connection more secure, less prone to breakage and damage, and improving service life.

[0016] Preferably, the exhaust mechanism includes a bracket and a piston plate, wherein both sides of the bracket are fixedly mounted on one side of the extrusion plate, and one side of the extrusion plate has a plurality of circular holes, wherein the outer surface dimension of the piston plate is larger than the inner wall dimension of the circular holes; and a fourth spring, wherein the two ends of the second spring are fixedly mounted on one side of the piston plate and one side of the bracket, respectively.

[0017] The effect achieved by the above components is as follows: by setting up an exhaust mechanism, after the extrusion plate squeezes and breaks the air bubbles inside the low-modulus glue inside the rotating barrel, the gas leaks out and enters the round hole, thereby pushing the piston plate to move towards one end of the bracket, causing the fourth spring to contract, so that the squeezed gas is discharged from the round hole, avoiding the re-aggregation of air bubbles, improving degassing efficiency, and optimizing product quality.

[0018] Preferably, the exhaust mechanism further includes a support rod, wherein the outer surface of the support rod is inserted into the inner wall of the fourth spring, and one end passes through one side of the bracket and is fixedly installed on one side of the piston plate.

[0019] The effect achieved by the above components is that by setting up support rods, the inner wall of the fourth spring can be supported and reinforced, making it less prone to bending and damage during use, and improving its service life.

[0020] The beneficial effects of this utility model are:

[0021] By incorporating auxiliary devices and a drive mechanism, the equipment effectively degasses the adhesive by combining centrifugal force, mechanical extrusion, and a vacuum environment. The rotating frame drives the drum to rotate synchronously, and the reciprocating motion of the extrusion plate against the inner wall of the drum utilizes the synergistic effect of extrusion and centrifugation to break, merge, and rapidly expel air bubbles, thereby improving degassing efficiency and adhesive quality. The design of the venting mechanism, pins, and reinforcing rods enhances intervention with the adhesive, further promoting bubble breakage and expulsion, improving overall degassing efficiency and equipment durability, and ensuring high-quality production of low-modulus adhesives.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figure 1-6 The vacuum mixing and degassing machine for producing low-modulus adhesives shown includes a degassing machine body 1 and a rotating drum 5. A rotating frame 4 is rotatably mounted on the inner wall of the degassing machine body 1, with the rotating drum 5 inserted into the inner wall of the rotating frame 4. A cover 3 is detachably mounted on the inner wall of the degassing machine body 1 via spring clips. An auxiliary device 2 is provided on one side of the cover. The auxiliary device 2 can drive the drive mechanism 23 to move by rotating the rotating frame 4, thereby driving the extrusion plate 22 to reciprocate on the outer surface of the slide rod 21, extruding the degassed low-modulus adhesive inside the rotating drum 5 to achieve the effect of auxiliary degassing treatment. It should be noted that the degassing machine body 1 is a mature technology and equipment in the prior art, and its internal structure, connection method and principle will not be described further.

[0033] Figure 1-6The auxiliary device 2 shown includes a slide bar 21, one side of which is fixedly mounted on one side of the machine cover 3; an extrusion plate 22, the inner wall of which is slidably mounted on the outer surface of the slide bar 21 and inserted into the inner wall of the rotating drum 5; two drive mechanisms 23, which are disposed between one side of the extrusion plate 22 and one side of the machine cover 3, for driving the extrusion plate 22 to reciprocate up and down on the slide bar 21 and in the inner wall of the rotating drum 5; a third spring 25, the inner wall of which is sleeved on the outer surface of the slide bar 21, and both ends are fixedly mounted on one side of the machine cover 3 and one side of the extrusion plate 22 respectively; and several venting mechanisms 26, which are disposed on one side of the extrusion plate 22, and can discharge the gas in the bubbles from one side of the extrusion plate 22 when the extrusion plate 22 extrudes and removes bubbles from the low modulus glue inside the rotating drum 5. By setting auxiliary device 2, when degassing the internal air bubbles of low-modulus adhesive using the degassing machine body 1 during the production process, the low-modulus adhesive is placed inside the rotating drum 5, and then the rotating drum 5 is placed on the rotating frame 4 and fixed. At this time, the extrusion plate 22 on the machine cover 3 is inserted into the rotating drum 5, and the machine cover 3 is closed, so that the spring clip on the degassing machine body 1 fixes the machine cover 3. One end of the spring clip is inserted into the inner wall of the outer surface of the machine cover 3, and the other end is slidably installed in the inner wall of the degassing machine body 1, and one side is connected to the inner wall of the degassing machine body 1 by a spring. During the degassing process, the drive motor inside the degassing machine body 1 can be started to drive the rotating frame 4 to rotate at high speed through the coupling, which drives the rotating drum 5 to move synchronously. The degassing machine utilizes centrifugal force to induce radial flow of the adhesive, which, combined with the vacuum environment inside the main body 1, enables the separation and removal of air bubbles. As the rotating frame 4 rotates, it drives the drive mechanism 23, which, in conjunction with the reset of the third spring 25, causes the extrusion plate 22 to reciprocate up and down within the inner wall of the slide rod 21 and the rotating drum 5. The positive thrust generated by mechanical extrusion breaks the shear gradient formed by the centrifugal force field, forcing air bubbles in dead zones to detach from the adhesive. Simultaneously, the synergistic effect of extrusion and centrifugation creates a pulsed pressure field, causing the air bubbles to continuously expand and merge under alternating forces, ultimately escaping rapidly in the vacuum environment. The bubbles are then discharged through the exhaust mechanism 26 on one side of the extrusion plate 22, achieving efficient degassing and improving the quality of the final product. The auxiliary device 2 also includes several pins 24, one side of which is fixedly installed on the side of the extrusion plate 22 away from the third spring 25. The pins 24 enhance mechanical intervention on the adhesive during degassing, especially in dead zones, effectively disrupting bubble aggregation and promoting bubble rupture and removal.

[0034] Figure 1-6The drive mechanism 23 shown includes several abutment frames 231, one side of which is fixedly mounted on the outer surface of the rotating frame 4; two U-shaped air cylinders 232, both ends of which are installed through the cover 3 on one side; a first piston rod 233, one end of which is installed through the inner wall of one end of the U-shaped air cylinder 232, and the other end abuts against one side of the abutment frame 231; and a first spring 234, the inner wall of which is sleeved on the outer surface of one end of the first piston rod 233, and both ends are fixedly mounted on one side of the first piston rod 233. The first piston rod 235 is installed on one side of the inner wall of the U-shaped air cylinder 232 away from the first piston rod 233, and the other end is fixedly installed on one side of the extrusion plate 22. The first piston rod 233 and the second piston rod 235 form a sealed space between the U-shaped air cylinder 232; the second spring 236 is sleeved on the outer surface of one end of the second piston rod 235, and both ends are fixedly installed on one side of the second piston rod 235 and one side of the inner wall of the U-shaped air cylinder 232, respectively. By setting the drive mechanism 23, when the rotating frame 4 rotates, it will drive several abutment frames 231 to move in a circular motion. After rotating to a certain angle, one side of the abutment frame will abut against one side of the first piston rod 233, causing it to slide upward in the U-shaped air cylinder 232. This will cause the first spring 234 to stretch, squeezing the air inside the U-shaped air cylinder 232 to move to one end, pushing the second piston rod 235 to slide to one end, causing the second spring 236 to contract, thereby pushing the extrusion plate 22 to slide downward on the slide rod 21. The low-modulus adhesive inside the rotating drum 5 is squeezed and the air bubbles that have not been expelled are squeezed and broken. At this time, the third spring 25 is in a stretched state. When the first piston rod 233 is completely removed from the abutment frame 231, the first spring 234 will drive the first piston rod 233 to reset. At the same time, the second spring 236 and the third spring 25 will also drive the second piston rod 235 and the extrusion plate 22 to reset respectively, in preparation for subsequent extrusion. Therefore, the drive mechanism 23 can drive the extrusion plate 22 to move up and down reciprocally inside the rotating drum 5.

[0035] Figure 1-6 The drive mechanism 23 shown also includes two rollers 238, which are rotatably mounted in the inner wall of one end of the first piston rod 233. By providing the rollers 238, the contact wear between one end of the first piston rod 233 and the abutment frame 231 can be reduced, facilitating their contact and pushing. Reinforcing rods 237 are fixedly mounted on both sides of one end of the second piston rod 235, with one side of the reinforcing rod 237 fixedly mounted on one side of the extrusion plate 22. By providing the reinforcing rods 237, the connection area between one end of the second piston rod 235 and the extrusion plate 22 can be increased, making the connection more robust, less prone to breakage and damage, and extending its service life.

[0036] Figure 1-6 The exhaust mechanism 26 shown includes a bracket 262 and a piston plate 264. Both sides of the bracket 262 are fixedly mounted on one side of the extrusion plate 22. One side of the extrusion plate 22 has several circular holes 261. The outer surface dimension of the piston plate 264 is larger than the inner wall dimension of the circular holes 261. A fourth spring 263 is also included, with the two ends of the second spring 236 fixedly mounted on one side of the piston plate 264 and one side of the bracket 262, respectively. By setting up the exhaust mechanism 26, after the extrusion plate 22 crushes the air bubbles inside the low-modulus adhesive in the rotating drum 5, the leaking gas enters the circular holes 261, thereby pushing the piston plate 264 towards one end of the bracket 262. This causes the fourth spring 263 to contract, allowing the extruded gas to be discharged from the circular holes 261, preventing the bubbles from re-aggregating, improving degassing efficiency, and optimizing product quality. The exhaust mechanism 26 also includes a support rod 265, the outer surface of which is inserted into the inner wall of the fourth spring 263, and one end of which passes through one side of the bracket 262 and is fixedly installed on one side of the piston plate 264. By setting the support rod 265, the inner wall of the fourth spring 263 can be supported and reinforced, making it less prone to bending and damage during use, thus improving its service life.

[0037] Working principle: During the production of low-modulus adhesive, when using the degassing machine body 1 to degas the internal air bubbles, the low-modulus adhesive is placed inside the rotating drum 5, and then the rotating drum 5 is placed on the rotating frame 4 and fixed. At this time, the extrusion plate 22 on the machine cover 3 is inserted into the rotating drum 5, and the machine cover 3 is closed, so that the spring clip on the degassing machine body 1 fixes the machine cover 3. One end of the spring clip is inserted into the inner wall of the outer surface of the machine cover 3, and the other end is slidably installed in the inner wall of the degassing machine body 1, and one side is connected to the inner wall of the degassing machine body 1 by a spring. Degassing... During processing, the drive motor inside the degassing machine body 1 can be started to drive the rotating frame 4 to rotate at high speed via a coupling, causing the rotating drum 5 to move synchronously. Centrifugal force is used to cause the glue to flow radially, which, combined with the vacuum environment inside the degassing machine body 1, achieves the separation and discharge of air bubbles. When the rotating frame 4 rotates, it drives several abutment frames 231 to move in a circular motion. After rotating to a certain angle, one side of the abutment frame will abut against one side of the first piston rod 233, causing it to slide upward in the U-shaped air cylinder 232, causing the first spring 234 to stretch and compressing the air inside the U-shaped air cylinder 232 to one end. The movement pushes the second piston rod 235 to slide to one end, causing the second spring 236 to contract. This pushes the extrusion plate 22 downward on the slide rod 21. At this time, the third spring 25 is in a stretched state. When the first piston rod 233 is completely removed from the abutment frame 231, the first spring 234 will drive the first piston rod 233 to return to its original position. At the same time, the second spring 236 and the third spring 25 will also drive the second piston rod 235 and the extrusion plate 22 to return to their original positions, preparing for subsequent extrusion. Therefore, the extrusion plate 22 moves up and down reciprocally within the slide rod 21 and the inner wall of the rotating drum 5. By utilizing the positive thrust generated by mechanical extrusion, the shear gradient formed by the centrifugal force field is broken, forcing the bubbles in the dead zone to detach from the colloidal binding. At the same time, the synergistic effect of extrusion and centrifugation forms a pulsed pressure field, causing the bubbles to continuously expand and merge during the alternating force process. Finally, they escape rapidly in a vacuum environment, and the gas released after rupture enters the interior of the circular hole 261, thereby pushing the piston plate 264 to move towards one end of the support 262, causing the fourth spring 263 to contract, so that the extruded gas is discharged from the circular hole 261, thus achieving a highly efficient degassing effect and improving the quality of the final product.
