Description

Technical Field

[0001] This invention relates to the field of impregnation tank technology, specifically an intelligent impregnation tank. Background Technology

[0002] In the impregnation process of textiles and composite materials, traditional impregnation tanks generally use fixed roller conveyors and an integrated lifting mechanism to complete the introduction, impregnation, and removal of fabric. Adhesive quantity control relies on the integrated lifting equipment, which has high driving power and slow response, making it difficult to fine-tune the pressure at a single point, resulting in uneven adhesive flow on the fabric surface. During fabric threading, the entire roller system needs to be lifted or disassembled, limiting manual operation space and increasing labor intensity. It is impossible to adjust the fabric tension or slack in real time through differential speed, affecting the impregnation depth and uniformity. Fabric flow is also controlled by a scraper, which causes significant damage to the fabric surface and does not utilize a compression method to establish a correlation between roller compression pressure and adhesive quantity, failing to achieve adhesive quantity adjustment through compression pressure regulation. Therefore, there is an urgent need for an intelligent impregnation device with independent pressure adjustment for each roller, rapid fabric threading, and closed-loop adhesive quantity adjustment functions with differential speed tension control. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an intelligent impregnation tank that can solve the problems in the prior art.

[0004] This invention is achieved through the following technical solution: An intelligent impregnation tank of this invention includes a box body, a heating device at the bottom of the box body, multiple rotating seats fixedly mounted on the top of the box body, an upper rotating cylinder rotatably mounted between the rotating seats on the left and right sides, a support frame mounted above the box body, and a lifting device for lifting the support frame mounted on the box body. The support frame is characterized by having a pressing power device on the front and rear sides of its top, which compresses and conveys the fabric and changes its adhesive content. A crossbeam is fixedly mounted on the left and right sides of the support frame, and a connecting rod is fixedly mounted on the lower side of each crossbeam. A mating plate is fixedly mounted on one side of each connecting rod, and multiple transition rollers rotatably mounted between the mating plates. The lifting device drives the support frame, connecting rods, mating plates, and transition rollers to rise, so that the transition rollers are located on both sides of the upper rotating cylinder.

[0005] A further technical solution involves introducing fabric from one of the extrusion power devices, passing it sequentially over the lower surface of the transition roller and the upper surface of the upper rotating drum, and then drawing it out from another extrusion power device. The inside of the housing is filled with adhesive. After the adhesive is heated by a heating device, the fabric is impregnated with the adhesive. The extrusion power device at the input end continues to operate, while the extrusion power device at the output end stops operating, causing the fabric around the transition roller and the upper rotating drum to extend. After being reset by a lifting device, the extended fabric is pulled back together by the transition roller and the upper rotating drum, and the fabric is impregnated with the adhesive.

[0006] A further technical solution involves adjusting the tension of the fabric on the outer surface of the transition roller and the upper rotating drum by changing the operating speed of the extrusion power devices on both sides.

[0007] In a further technical solution, the mating plate is provided with a plurality of circular holes, and the two sides of the circular holes are provided with chamfers. When the mating plate is moved to the uppermost side, the circular holes are engaged with the outer surface of the upper rotating cylinder.

[0008] A further technical solution includes a heating device comprising a heat-conducting plate fixed inside the housing, wherein a plurality of electric heating rods are fixedly disposed inside the heat-conducting plate. When the electric heating rods are in operation, they heat the heat-conducting plate, and the heat-conducting plate transfers heat to the adhesive.

[0009] A further technical solution includes a lifting device comprising multiple hydraulic cylinders fixed to the outer surface of the box body, wherein each hydraulic cylinder is provided with a telescopic rod, and the telescopic rod is fixedly connected to the bracket.

[0010] A further technical solution includes an extrusion power device comprising a vertical plate fixed in the bracket, the vertical plate being disposed on the left and right sides of the bracket, a second rotating drum being rotatably disposed between the vertical plates, a sliding seat being slidably disposed on one side of the vertical plate, a first rotating drum being rotatably disposed between the sliding seats, a threaded shaft lifting assembly being disposed on one side of the vertical plate to drive the sliding seat and the first rotating drum to move up and down, a guide rail slider assembly being disposed between the sliding seat and the vertical plate, and a second servo motor being fixed on one side of the vertical plate, the second servo motor being poweredly connected to the second rotating drum.

[0011] A further technical solution is that a motor mounting plate is fixed on one side of the upright plate, and a sleeve mounting plate is fixed on one side of the sliding seat, with a miniature pressure gauge fixed on the sleeve mounting plate.

[0012] A further technical solution includes a threaded shaft lifting assembly comprising a first servo motor fixed to the bottom of the motor mounting plate, a through hole provided in the motor mounting plate, a threaded shaft being provided on one side of the first servo motor for power connection, the threaded shaft passing through the through hole, an internal threaded sleeve being fixed in the sleeve mounting plate, the threaded shaft passing through the internal threaded sleeve, and the threaded shaft being threadedly connected to the internal threaded sleeve.

[0013] A further technical solution includes a guide rail slider assembly comprising multiple slide rails fixed to one side of the upright plate, a left and a right fixed plate fixed to one side of the sliding seat, and a slider fixed to one side of the fixed plate, the slider being slidably connected to the slide rails.

[0014] The beneficial effects of this invention are as follows: First, this equipment uses an extrusion power device to drive and transport the fabric. In the extrusion power device at the output end, after the fabric is extruded by the first and second rotating drums, the excess adhesive will be squeezed and separated. Therefore, by changing the pressure of the first rotating drum and the sliding seat, the amount of adhesive flowing on the fabric can also be changed. Based on the data feedback from the micro pressure gauge, the first servo motor and the threaded shaft are made to work, so as to drive the first rotating drum and the sliding seat to move up and down, so that the pressure between the first and second rotating drums can be adjusted to make different amounts of adhesive flowing on the fabric.

[0015] 2. Using a lifting device, a pressing power device, and manual labor, the lifting device moves the mating plate and the transition roller upwards. When the circular hole is engaged in the upper rotating drum, it reaches the upper limit position. The transition roller and the upper rotating drum are on the same horizontal plane. The fabric is drawn out from the pressing power device at the input end and, under the manual traction of the personnel, passes around the lower side of the transition roller and then around the upper side of the upper rotating drum. At this time, it is convenient for manual splicing of the fabric.

[0016] Third, during the reset phase, the extrusion power device at the input end continues to input the fabric. As the distance between the transition roller and the upper rotating drum increases, the fabric introduced into the box also needs to become longer. When the extrusion power device at the output end is located on the upper side of the box, the operator can pass the fabric through the extrusion power device at the output end and then pull it out. By adjusting the operating speed of the extrusion power devices at the input and output ends, the fabric can be wound around the outer surface of the transition roller and the upper rotating drum and moved to adjust the movement speed and tension of the fabric.

After the fabric is introduced from one of the extrusion power devices, it passes through the lower surface of the transition roller 48 and the upper surface of the upper rotating drum 18 in sequence, and then is led out from another extrusion power device. The inside of the box 11 is filled with adhesive. After the adhesive is heated by the heating device, the fabric is impregnated with the adhesive.

[0020] Advantageously, the extrusion power device at the input end continues to operate, while the extrusion power device at the output end stops operating, causing the fabric around the transition roller 48 and the upper rotating drum 18 to extend. After being reset by the lifting device, the extended fabric is pulled back together by the transition roller 48 and the upper rotating drum 18, and the fabric is immersed in the adhesive.

[0021] Advantageously, the extrusion power devices at the input and output ends continue to operate thereafter, so that the fabric is continuously impregnated in the housing 11.

[0022] Advantageously, the tension of the fabric on the outer surface of the transition roller 48 and the upper rotating drum 18 is adjusted by changing the operating speed of the extrusion power devices on both sides. That is, when the operating speed of the extrusion power device at the input end is less than the operating speed of the extrusion power device at the output end, the fabric is stretched; or when the operating speed of the extrusion power device at the input end is greater than the operating speed of the extrusion power device at the output end, the fabric is relaxed.

[0029] Advantageously, the lifting device includes a plurality of hydraulic cylinders 13 fixed to the outer surface of the housing 11, and a telescopic rod 15 is provided inside the hydraulic cylinder 13, and the telescopic rod 15 is fixedly connected to the bracket 16.

[0030] Advantageously, the extrusion power device includes a vertical plate 21 fixed in the bracket 16, the vertical plate 21 is disposed on the left and right sides of the bracket 16, a second rotating drum 29 is rotatably disposed between the vertical plates 21, a sliding seat 28 is slidably disposed on one side of the vertical plate 21, a first rotating drum 27 is rotatably disposed between the sliding seats 28, a threaded shaft lifting assembly is disposed on one side of the vertical plate 21 to drive the sliding seat 28 and the first rotating drum 27 to move up and down, a guide rail slider assembly is disposed between the sliding seat 28 and the vertical plate 21, and a second servo motor 32 is fixed on one side of the vertical plate 21, the second servo motor 32 is poweredly connected to the second rotating drum 29.

[0031] Advantageously, a motor mounting plate 35 is fixed on one side of the upright plate 21, and a sleeve mounting plate 36 is fixed on one side of the sliding seat 28. A miniature pressure gauge 25 is fixed on the sleeve mounting plate 36. After the outer surfaces of the first rotating cylinder 27 and the second rotating cylinder 29 abut against each other, the miniature pressure gauge 25 and the motor mounting plate 35 reach the limit of its measurement range. The miniature pressure gauge 25 adopts existing technology and needs to be equipped with a digital display when in use. After the miniature pressure gauge 25 touches the motor mounting plate 35, the magnitude of the contact pressure will change, and the digital display will show the real-time pressure magnitude.

[0032] Advantageously, the threaded shaft lifting assembly includes a first servo motor 22 fixed to the bottom of the motor mounting plate 35. The motor mounting plate 35 is provided with a through hole 23. A threaded shaft 26 is provided on one side of the first servo motor 22 for power connection. The threaded shaft 26 passes through the through hole 23. An internal threaded sleeve 24 is fixed in the sleeve mounting plate 36. The threaded shaft 26 passes through the internal threaded sleeve 24 and is threadedly connected to the internal threaded sleeve 24.

[0033] Advantageously, the guide rail slider assembly includes multiple slide rails 33 fixed to one side of the upright plate 21, and one fixed plate 34 on each side of the sliding seat 28. A slider 31 is fixed to one side of the fixed plate 34, and the slider 31 is slidably connected to the slide rail 33.

[0034] It also includes a controller, which is electrically connected to the lifting device, the extrusion power device, and the heating device. Specifically, the hydraulic cylinder 13 is electrically connected to the solenoid valve, the solenoid valve is electrically connected to the controller, the first servo motor 22 and the second servo motor 32 are electrically connected to the servo motor controller, the servo motor controller is electrically connected to the controller, the electric heating rod 46 is electrically connected to the gear adjuster, and a temperature sensor is also installed in the housing 11. The temperature sensor, the gear adjuster, and the controller are electrically connected. The controller can be a PLC, PC, or microcontroller, etc., and is used to control the operation of various devices in the equipment.

[0035] The rotation speed adjustment of the second servo motor 32 is achieved by adjusting the running speed of the second servo motor 32 through the servo motor controller, which can indirectly adjust the fabric conveying speed.

[0036] When the fabric is initially inserted into the equipment, the operator introduces the fabric into the extrusion device at the input end. The extrusion device presses the fabric, allowing a larger amount of fabric to enter the equipment. Subsequently, the hydraulic cylinder 13 pushes the telescopic rod 15 and the support 16 upwards to their upper limit positions, causing the mating plate 51 and the transition roller 48 to move upwards. When the circular hole 49 engages with the upper rotating drum 18, the upper limit position is reached. Figure 9 As shown, the transition roller 48 and the upper rotating drum 18 are located on the same horizontal plane. The fabric is drawn out from the extrusion power device at the input end and, under manual traction, passes under the transition roller 48 and then over the upper rotating drum 18. Before the fabric is introduced into the extrusion power device at the output end, a large amount of fabric is drawn out, the length of which is equal to the height of the box 11. Then, the hydraulic cylinder 13 drives the telescopic rod 15 to reset. The extrusion power device at the input end continues to run. As the distance between the transition roller 48 and the upper rotating drum 18 increases, the fabric introduced into the box 11 also needs to become longer. When the extrusion power device at the output end is located on the upper side of the box 11, the personnel can pass the fabric through the extrusion power device at the output end and then draw it out. By adjusting the running speed of the extrusion power devices at the input and output ends, the fabric can be wrapped around the outer surface of the transition roller 48 and the upper rotating drum 18 and moved.

[0037] The fabric is impregnated with adhesive inside the housing 11. After the electric heating rod 46 is working, it generates heat. The heat is transferred to the adhesive liquid inside the housing 11 through the heat conduction plate 47, so that the adhesive liquid impregnates the fabric. The heat insulation block 44 can be pulled out from the housing 11 to facilitate the dissipation of heat and to observe the working status of the electric heating rod 46.

[0038] When the extrusion power device is running, the first servo motor 22 rotates the threaded shaft 26. Since the threaded shaft 26 is threadedly connected to the internal threaded sleeve 24, the sliding seat 28 and the first rotating drum 27 can move upward through the structure of the slider 31, the slide rail 33 and the fixed plate 34. The fabric passes between the first rotating drum 27 and the second rotating drum 29. Then, the first servo motor 22 drives the sliding seat 28 and the first rotating drum 27 downward, so that the sliding seat 28 presses the fabric against the outer surface of the second rotating drum 29. The micro pressure gauge 25 feeds back the pressure value of the fabric being squeezed between the first rotating drum 27 and the second rotating drum 29. The second rotating drum 29 rotates under the drive of the second servo motor 32, which can drive and transport the fabric.

[0039] In the extrusion power device at the output end, after the fabric is impregnated with glue, the excess glue will be squeezed and separated after being squeezed by the first rotating drum 27 and the second rotating drum 29. Therefore, by changing the pressure of the first rotating drum 27 and the sliding seat 28, the amount of glue flowing on the fabric can also be changed. Based on the data feedback from the micro pressure gauge 25, the first servo motor 22 and the threaded shaft 26 are operated to drive the first rotating drum 27 and the sliding seat 28 to move up and down, so that the pressure between the first rotating drum 27 and the second rotating drum 29 can be adjusted to make different amounts of glue flowing on the fabric.

[0040] The threaded shaft 42, connecting rod 41, mating plate 51 and transition roller 48 extend into the housing 11, and the adhesive in the housing 11 impregnates the fabric on the outer surface of the transition roller 48.

[0041] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the scope of protection of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
