Description

Technical Field

[0001] The present invention belongs to the technical field of adhesive mixing, and particularly relates to a multi-layer board composite adhesive raw material mixing device. Background Art

[0002] Adhesives are one of the most important auxiliary materials and are widely used in packaging operations. An adhesive is a viscous substance that can connect two separated materials together by virtue of its viscosity.

[0003] When producing adhesives, it is necessary to mix the raw materials. When the existing adhesive raw material mixing device mixes the raw materials, due to the high viscosity of the adhesive raw materials, long-time mixing and stirring are required, which is time-consuming and laborious; and during mixing, many bubbles are likely to appear between the adhesive raw materials. The existing adhesive raw material mixing device heats the adhesive raw materials during stirring to accelerate the convergence and dissipation of the bubbles. However, due to the high viscosity of the adhesive raw materials themselves, the bubbles at the bottom are difficult to float upward and dissipate, further affecting the mixing effect of the adhesive raw materials. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-layer board composite adhesive raw material mixing device, aiming to solve the technical problem in the prior art that due to the high viscosity of the adhesive raw materials themselves, the bubbles at the bottom are difficult to float upward and dissipate, further affecting the mixing effect of the adhesive raw materials.

[0007] Further technical solution: The drainage mechanism includes a telescopic sleeve, a motor, a gear transmission pair, and a spray pipe. The fixed end of the telescopic sleeve is rotatably connected to the sliding plate. A motor is fixedly connected to the upper end surface of the mixing box. A gear transmission pair is connected between the output shaft of the motor and the telescopic end of the telescopic sleeve. A plurality of spray pipes are arc-shapedly arranged on the fixed end of the telescopic sleeve, and all the spray pipes are communicated with the telescopic sleeve. A spiral conveying mechanism capable of vertically conveying materials is arranged in the telescopic sleeve.

[0008] Further technical solution: A plurality of guide plates are connected to the fixed end of the telescopic sleeve, and all the guide plates are arranged close to the sliding plate. A guide hole is arranged at the connection position of the guide plate and the telescopic sleeve. A plurality of guide grooves are arranged in the side wall of the telescopic sleeve. One end of each guide groove is communicated between the conical filter sleeve and the conical electric heating sleeve, and the other end of each guide groove is communicated to the lower side of the sliding plate.

[0009] Further technical solution: The separation assembly includes a conical filter sleeve and a sliding frame. The conical filter sleeve is fixedly connected to the sliding frame. The conical filter sleeve is rotatably connected to the fixed end of the telescopic sleeve. The sliding frame is vertically slidably connected to the inner wall of the mixing box.

[0010] Further technical solution: The scraping component includes a sleeve, a scraping plate, and an air pump. A fixed sleeve is fixedly connected to the side wall of the conical filter sleeve. The fixed sleeve is rotatably connected to a sleeve, and a driving component for driving the sleeve to rotate is arranged in the fixed sleeve. A certain gap is maintained between the sleeve and the conical electric heating sleeve. A plurality of scraping plates are arranged on the side wall of the sleeve along the same rotation direction, and all the scraping plates are communicated with the sleeve.

[0012] Further technical solution: The mixing mechanism includes a rotating rod, mixing plates, and a second electric heating mesh plate; The rotating rod is fixedly connected to the bottom of the telescopic sleeve. The rotating rod is fixedly connected with multiple mixing plates and a second electric heating mesh plate, and the second electric heating mesh plates are all arranged close to the sliding plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the electric telescopic rod drives the sliding plate to rise in height, the air pressure in the space below the filtering mechanism decreases at this time. Under the action of negative pressure, the bubbles in the raw material below the sliding plate are collected upward to a position close to the liquid level below the sliding plate. When the negative pressure of the space below the sliding plate reaches the set air pressure value, the one-way solenoid valve is conducted at this time, and the raw material above the sliding plate passes through the filter mesh plate and reaches below the sliding plate. At this time, the bubbles above the sliding plate are intercepted above the sliding plate; then the electric telescopic rod drives the sliding plate to descend in height. At this time, under the action of liquid pressure, all the sealing plates turn upward, and the raw material below the sliding plate together with the bubbles floating at the liquid level position below the sliding plate are discharged to above the sliding plate; during the process of the electric telescopic rod driving the sliding plate to reciprocate vertically, the bubbles in the mixing tank can be continuously collected above the sliding plate, which is convenient for the bubbles to dissipate concentratedly.

[0014] 2. When the raw material in the telescopic sleeve is sprayed out through the spray pipe, the conical filter sleeve filters and collects the impurities and bubbles in the raw material at this time. And under the filtering action of the conical filter sleeve, the raw material can overcome its own viscosity and be fully dispersed and collected in the conical electric heating sleeve for mixing, improving the mixing effect of the material; under the rotation of the telescopic sleeve, the raw material in the telescopic sleeve can be evenly dispersed on the inner wall of the conical electric heating sleeve. At this time, the raw material can be quickly heated through the conical electric heating sleeve, and at the same time, the bubbles in the raw material can also be quickly discharged to the surface of the raw material.

[0015] 3. When the raw material is spread on the inner wall of the conical electric heating sleeve, due to the heating of the conical electric heating sleeve, the bubbles in the conical electric heating sleeve concentrate on the surface of the piled-up raw material. At this time, the driving component drives the sleeve to rotate, and the sleeve drives the scraper to collect the bubbles and part of the raw material on the surface of the raw material into the sleeve. The first electric heating mesh plate in the sleeve eliminates the bubbles in this part of the raw material concentratedly, improving the defoaming effect of the raw material.

[0016] 4. Driven by the telescopic sleeve, all the scraping bars rotate simultaneously. The raw material on the inner wall of the conical electric heating sleeve is collected through the scraping bars, so that the raw material on the inner wall of the conical electric heating sleeve can be concentrated towards the bottom of the mixing tank of the conical electric heating sleeve. At this time, in the scraping bars, the bubbles in the raw material are filtered and eliminated through multiple metal mesh plates, further improving the elimination effect of the bubbles in the raw material.

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0028] Such as Figures 1 - 7As shown in the figure, a multi-layer board composite adhesive raw material mixing device provided by the present invention includes a mixing tank 1. A filtering mechanism 2 is arranged in the mixing tank 1. The filtering mechanism 2 can filter impurities and foam upward in the mixing tank 1 by reciprocating vertically. A drainage mechanism 3 is connected to the filtering mechanism 2. The drainage mechanism 3 can convey the materials above the filtering mechanism 2 upward and spray the raw materials into the separation component 4 by continuously rotating. A separation component 4 is arranged outside the drainage mechanism 3. The separation component 4 is slidably connected to the inner wall of the mixing tank 1. The separation component 4 can filter and disperse the raw materials. The drainage mechanism 3 is fixedly connected with a conical electric heating sleeve 5. The conical electric heating sleeve 5 is arranged outside the separation component 4. The conical electric heating sleeve 5 can collect and heat the raw materials. A scraping component 6 and an aggregate component 7 are connected to the outside of the separation component 4. The aggregate component 7 is used for centralized defoaming of the accumulated materials. The scraping component 6 can collect the materials on the inner wall of the conical electric heating sleeve 5. The drainage mechanism 3 is connected with a mixing mechanism 8. The mixing mechanism 8 is arranged below the filtering mechanism 2. The mixing mechanism 8 can mix and heat the raw materials.

[0029] In this embodiment, the raw materials are poured into the mixing tank 1 through the feed pipe 13. Then the drainage mechanism 3 is started. The drainage mechanism 3 drives the guide plate 11 to mix and stir all the raw materials. During this process, the filtering mechanism 2 drives the drainage mechanism 3 to reciprocate vertically in the mixing tank 1, thereby increasing the mixing effect of the drainage mechanism 3 on the raw materials. During this process, the filtering mechanism 2 can filter impurities and foam upward to the upper side of the filtering mechanism 2 in the mixing tank 1 by reciprocating vertically. The drainage mechanism 3 can convey the materials above the filtering mechanism 2 upward and spray the raw materials into the separation component 4 by continuously rotating. Then the separation component 4 filters and collects the impurities in the raw materials. Then the conical electric heating sleeve 5 can collect and heat the raw materials, so that the bubbles rise and dissipate. At the same time, the aggregate component 7 is used for centralized defoaming of the accumulated materials, increasing the defoaming effect of the raw materials. At this time, the scraping component 6 can collect the materials on the inner wall of the conical electric heating sleeve 5 and convey them to the lower part of the filtering mechanism 2. Below the filtering mechanism 2, the mixing mechanism 8 can mix and heat the raw materials, so that the bubbles in the materials below the filtering mechanism 2 rise to the liquid surface position and dissipate.

[0030] Such as Figure 4As shown in the figure, a multi-layer board composite adhesive raw material mixing device provided by the present invention, the filtering mechanism 2 includes an electric telescopic rod 21 and a sliding plate 22. The bottom of the mixing tank 1 is fixedly connected with an electric telescopic rod 21, and the telescopic end of the electric telescopic rod 21 is fixedly connected with a sliding plate 22. The sliding plate 22 is slidably and sealingly connected to the inner wall of the mixing tank 1. A plurality of first diversion holes 23 and second diversion holes 25 are provided on the sliding plate 22. A sealing plate 24 is rotatably connected to each of the first diversion holes 23 through an elastic torsion spring. The sealing plate 24 can be turned upward unidirectionally. A filter screen plate 26 is fixedly arranged in the second diversion hole 25, and a one-way solenoid valve 27 that conducts unidirectionally to the bottom of the sliding plate 22 is arranged at the second diversion hole 25.

[0031] In this embodiment, when the electric telescopic rod 21 drives the sliding plate 22 to rise in height, the air pressure in the space below the filtering mechanism 2 decreases at this time. Under the action of negative pressure, the bubbles in the raw materials below the sliding plate 22 are collected upward to a position close to the liquid level below the sliding plate 22. When the negative pressure in the space below the sliding plate 22 reaches the set air pressure value, the one-way solenoid valve 27 is conducted at this time, and the raw materials above the sliding plate 22 pass through the filtering of the filter screen plate 26 and reach below the sliding plate 22. At this time, the bubbles above the sliding plate 22 are intercepted above the sliding plate 22. After that, the electric telescopic rod 21 drives the sliding plate 22 to descend in height. At this time, under the action of liquid pressure, all the sealing plates 24 are turned upward, and the raw materials below the sliding plate 22 together with the bubbles floating at the liquid level position below the sliding plate 22 are discharged to above the sliding plate 22. During the process of the electric telescopic rod 21 driving the sliding plate 22 to reciprocate vertically, the bubbles in the mixing tank 1 can be continuously collected above the sliding plate 22, which is convenient for the bubbles to dissipate concentratedly.

[0032] During this process, the sliding plate 22 drives the diversion mechanism 3 and the mixing mechanism 8 to reciprocate vertically, and the raw materials are continuously mixed through the diversion mechanism 3 and the mixing mechanism 8.

[0033] As Figure 3 shown in the figure, a multi-layer board composite adhesive raw material mixing device provided by the present invention, the diversion mechanism 3 includes a telescopic sleeve 31, a motor 32, a gear transmission pair 33 and a spray pipe 34; The fixed end of the telescopic sleeve 31 is rotatably connected to the sliding plate 22. The upper end face of the mixing tank 1 is fixedly connected with a motor 32. A gear transmission pair 33 is connected between the output shaft of the motor 32 and the telescopic end of the telescopic sleeve 31. A plurality of spray pipes 34 are arc-shapedly arranged on the fixed end of the telescopic sleeve 31, and all the spray pipes 34 are communicated with the telescopic sleeve 31. A spiral conveying mechanism capable of vertically conveying materials is arranged in the telescopic sleeve 31.

[0034] In this embodiment, under the conveyance of the screw conveyor mechanism, the raw materials, together with impurities and air bubbles, on the upper side of the slide plate 22 are conveyed upward through the telescopic sleeve 31. The motor 32 is started, and the motor 32 drives the telescopic sleeve 31 to rotate through the gear transmission pair 33. The telescopic sleeve 31 sprays the raw materials outward through the nozzle 34, and then the air bubbles and impurities in the raw materials are intercepted in the separation component 4 through the separation component 4.

[0035] As Figure 4 shown, a multi-layer board composite adhesive raw material mixing device provided by the present invention, a plurality of guide plates 11 are connected to the fixed end of the telescopic sleeve 31, all the guide plates 11 are arranged at positions close to the slide plate 22, a guide hole 12 is arranged at the connection position of the guide plate 11 and the telescopic sleeve 31, and a plurality of material guide grooves 10 are arranged in the side wall of the telescopic sleeve 31. One end of each of the material guide grooves 10 communicates between the conical filter sleeve 41 and the conical electric heating sleeve 5, and the other end of each of the material guide grooves 10 communicates to the lower side of the slide plate 22.

[0036] In this embodiment, the telescopic sleeve 31 drives the guide plate 11 to mix the raw materials on the upper side of the slide plate 22. During this process, the materials on the upper side of the slide plate 22 enter the inner cavity of the telescopic sleeve 31 through the guide hole 12, and then are sprayed outward under the conveyance of the screw conveyor mechanism.

[0037] As Figure 3 shown, a multi-layer board composite adhesive raw material mixing device provided by the present invention, the separation component 4 includes a conical filter sleeve 41 and a sliding frame 42. The conical filter sleeve 41 is fixedly connected to the sliding frame 42. The conical filter sleeve 41 is rotatably connected to the fixed end of the telescopic sleeve 31, and the sliding frame 42 is vertically slidably connected to the inner wall of the mixing box 1.

[0038] In this embodiment, when the raw materials in the telescopic sleeve 31 are sprayed outward through the nozzle 34, at this time, the conical filter sleeve 41 filters and collects the impurities and air bubbles in the raw materials. And under the filtering action of the conical filter sleeve 41, the raw materials can overcome their own viscosity and be fully dispersed and collected in the conical electric heating sleeve 5 for mixing, improving the mixing effect of the materials; And under the rotation of the telescopic sleeve 31, the raw materials in the telescopic sleeve 31 can be evenly dispersed on the inner wall of the conical electric heating sleeve 5. At this time, the conical electric heating sleeve 5 can quickly heat the raw materials, and at the same time, the air bubbles in the raw materials can also quickly escape to the surface of the raw materials.

[0039] As Figure 6 shown, a multi-layer board composite adhesive raw material mixing device provided by the present invention, the scraping component 6 includes a sleeve 61, a scraping plate 62 and an air pump 63; The side wall of the conical filter sleeve 41 is fixedly connected with a fixed sleeve 9. The fixed sleeve 9 is rotatably connected with a sleeve 61. A driving component for driving the sleeve 61 to rotate is arranged in the fixed sleeve 9. Preferably, the driving component drives the sleeve 61 to rotate through an AC motor 32 and a gear transmission component; A certain gap is maintained between the sleeve 61 and the conical electric heating sleeve 5. A plurality of scraping plates 62 are arranged on the side wall of the sleeve 61 along the same rotation direction. All the scraping plates 62 are communicated with the sleeve 61. A first electric heating grid plate is spirally arranged in the scraping plate 62. The fixed sleeve 9 is fixedly connected with an air pump 63. The air pump 63 is communicated with the sleeve 61.

[0040] In this embodiment, when the raw material is spread on the inner wall of the conical electric heating sleeve 5, due to the heating effect of the conical electric heating sleeve 5, the air bubbles in the conical electric heating sleeve 5 concentrate on the surface of the piled-up raw material. At this time, the driving component drives the sleeve 61 to rotate. The sleeve 61 drives the scraping plates 62 to collect the air bubbles and part of the raw material on the surface of the raw material into the sleeve 61. The first electric heating grid plate in the sleeve 61 centrally eliminates the air bubbles in this part of the raw material, improving the defoaming effect of the raw material. The defoamed raw material falls to the bottom of the conical electric heating sleeve 5 and is collected under the filtering mechanism 2 through the material guiding groove 10.

[0041] As Figure 8 shown, a multi-layer board composite adhesive raw material mixing device provided by the present invention. The aggregate component 7 includes a scraping bar 71 and a metal mesh plate 72. The scraping bar 71 is fixedly connected with the side wall of the telescopic sleeve 31, and the scraping bar 71 is attached to the inner wall of the conical electric heating sleeve 5. A plurality of metal mesh plates 72 are arranged along the length direction in the scraping bar 71.

[0042] In this embodiment, driven by the telescopic sleeve 31, all the scraping bars 71 rotate simultaneously. The scraping bars 71 collect the raw material on the inner wall of the conical electric heating sleeve 5, enabling the raw material on the inner wall of the conical electric heating sleeve 5 to concentrate towards the bottom of the mixing box 1 of the conical electric heating sleeve 5. At this time, in the scraping bar 71, the air bubbles in the raw material are filtered and eliminated through a plurality of metal mesh plates 72, further improving the elimination effect of the air bubbles in the raw material.

[0043] As Figure 5 shown, a multi-layer board composite adhesive raw material mixing device provided by the present invention. The mixing mechanism 8 includes a rotating rod 81, a mixing plate 82 and a second electric heating grid plate 83; The rotating rod 81 is fixedly connected with the bottom of the telescopic sleeve 31. The rotating rod 81 is fixedly connected with a plurality of mixing plates 82 and a second electric heating grid plate 83. The second electric heating grid plates 83 are all arranged close to the sliding plate 22.

[0044] In this embodiment, the telescopic sleeve 31 drives the rotating rod 81 to rotate, and the rotating rod 81 drives the mixing plate 82 to mix and stir the raw materials on the lower side of the sliding plate 22. During the process of the electric telescopic rod 21 driving the sliding plate 22 to rise, under the action of negative pressure, the bubbles on the lower side of the sliding plate 22 are collected towards the liquid surface on the lower side of the sliding plate 22. The second electric heating grid plate 83 can collect and heat these bubbles to eliminate them, improving the overall defoaming effect of the raw materials in the mixing tank 1.

[0045] Working principle: Pour the raw materials into the mixing tank 1 through the feed pipe 13, and then start the drainage mechanism 3. The drainage mechanism 3 drives the material guiding plate 11 to mix and stir all the raw materials. During this process, the filtering mechanism 2 drives the drainage mechanism 3 to move vertically back and forth in the mixing tank 1, thereby increasing the mixing effect of the drainage mechanism 3 on the raw materials; During this process, the filtering mechanism 2 can filter impurities and foam upward to the upper side of the filtering mechanism 2 in the mixing tank 1 by means of reciprocating vertical movement. Specifically, when the electric telescopic rod 21 drives the sliding plate 22 to rise in height, the air pressure in the space below the filtering mechanism 2 decreases at this time. Under the action of negative pressure, the bubbles in the raw materials on the lower side of the sliding plate 22 are collected upward to a position close to the liquid surface on the lower side of the sliding plate 22. When the negative pressure of the space below the sliding plate 22 reaches the set air pressure value, the one-way solenoid valve 27 is conducted at this time, and the raw materials on the upper side of the sliding plate 22 pass through the filter mesh plate 26 and reach the lower side of the sliding plate 22. At this time, the bubbles on the upper side of the sliding plate 22 are intercepted on the upper side of the sliding plate 22; then the electric telescopic rod 21 drives the sliding plate 22 to descend in height. At this time, under the action of liquid pressure, all the sealing plates 24 turn upward, and the raw materials on the lower side of the sliding plate 22 together with the bubbles floating on the liquid surface position on the lower side of the sliding plate 22 are discharged to the upper side of the sliding plate 22; during the process of the electric telescopic rod 21 driving the sliding plate 22 to move vertically back and forth, the bubbles in the mixing tank 1 can be continuously collected to the upper side of the sliding plate 22, facilitating the centralized dissipation of the bubbles.

[0046] Then the telescopic sleeve 31 drives the material guiding plate 11 to mix the raw materials on the upper side of the sliding plate 22. During this process, the materials on the upper side of the sliding plate 22 enter the inner cavity of the telescopic sleeve 31 through the guide holes 12, and then are ejected outward under the transmission of the screw conveyor mechanism. When the raw materials in the telescopic sleeve 31 are ejected outward through the spray pipe 34, the conical filter sleeve 41 filters and collects the impurities and bubbles in the raw materials at this time. And under the filtering action of the conical filter sleeve 41, the raw materials can overcome their own viscosity and be fully dispersed and collected in the conical electric heating sleeve 5 for mixing, improving the mixing effect of the materials; under the rotation of the telescopic sleeve 31, the raw materials in the telescopic sleeve 31 can be evenly dispersed on the inner wall of the conical electric heating sleeve 5. At this time, the conical electric heating sleeve 5 can quickly heat the raw materials, and at the same time, the bubbles in the raw materials can also be quickly discharged to the surface of the raw materials.

[0047] When the raw materials are spread on the inner wall of the conical electric heating sleeve 5, due to the heating effect of the conical electric heating sleeve 5, the bubbles in the conical electric heating sleeve 5 concentrate on the surface of the piled-up raw materials. At this time, the driving assembly drives the sleeve 61 to rotate, and the sleeve 61 drives the scraper 62 to collect the bubbles on the surface of the raw materials together with part of the raw materials into the sleeve 61. The first electric heating grid plate in the sleeve 61 eliminates the bubbles in this part of the raw materials intensively, improving the defoaming effect of the raw materials. The defoamed raw materials fall to the bottom of the conical electric heating sleeve 5 and are collected under the filtering mechanism 2 through the material guiding groove 10; Moreover, driven by the telescopic sleeve 31, all the scraping bars 71 rotate simultaneously. The scraping bars 71 collect the raw materials on the inner wall of the conical electric heating sleeve 5, enabling the raw materials on the inner wall of the conical electric heating sleeve 5 to concentrate towards the bottom of the mixing box 1 of the conical electric heating sleeve 5. At this time, in the scraping bars 71, the bubbles in the raw materials are filtered and eliminated through multiple metal mesh plates 72, further improving the defoaming effect of the bubbles in the raw materials.
