Description

Technical Field

[0001] The present invention relates to the technical field of vacuum insulation board core material preparation, in particular to a wet process production device for vacuum insulation board core material. Background Art

[0002] Vacuum insulation panels are mainly composed of three parts: internal fiberglass core material, external high-barrier coating material, and getter that can absorb moisture and some types of gases. The current wet molding production method only uses roller extrusion and vacuum pump under the molding mesh belt to remove the wet core material that has just been formed from the pulp pool.

[0003] For example, a new wet forming device for preparing core materials of vacuum insulation boards with announcement number CN215892984U includes a frame, a flow box is provided at the front end of the frame, a driving roller is rotatably connected to the top of the rear end of the frame, a motor 1 is provided on one side of the frame, one end of the driving roller is connected to the output shaft of the motor 1, a driven roller is rotatably connected to the middle and lower part of the flow box, a mesh curtain is wound between the driving roller and the driven roller, a negative pressure rolling assembly and a negative pressure box assembly are provided in the middle part of the frame, the negative pressure rolling assembly is arranged above the mesh curtain, the negative pressure box assembly is arranged between two layers of mesh curtains, and the negative pressure box The body component is arranged below the negative pressure rolling component. The negative pressure main pipe and concave pipe are combined with the upper and lower double-position negative pressure suction and water removal of the negative pressure box and the hollow roller rolling and squeezing of water. Most of the moisture in the core material can be removed in the first step, which can save energy in the subsequent core material drying process. However, since the position of the equipment mesh curtain is fixed, after a period of operation, the slurry at the mesh curtain position has a low fiber content, which will affect the subsequent fiber laying operation on the mesh curtain, and there is a lack of auxiliary laying structure. It is difficult to maintain uniform fiber laying only by relying on the mesh curtain's own transmission to drive the fiber laying, which affects the uniformity of the core material thickness and reduces the molding quality of the core material.

[0004] Therefore, a wet process production equipment for vacuum insulation board core material is proposed to solve the above-mentioned problems. Summary of the Invention

[0008] By adopting the above technical solution, the movable plates are moved closer to each other and the inclined push plates slide, so that the slurry is slowly pushed to the position of the active roller, and the fiber content at the feeding position of the mesh curtain is kept high, thereby facilitating the fiber feeding and laying operation.

[0022] By adopting the above technical solution, when the core material sheet passes upward between the squeezing roller and the negative pressure collection box, the moisture in the core material sheet is squeezed out, and the moisture enters the negative pressure collection box through the filter hole at the top of the negative pressure collection box. The negative pressure equipment is sucked through the drain pipe, and the water in the negative pressure collection box is collected in the drain pipe and discharged.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. Add water and centrifugal cotton to the pulping tank and soak them fully. After stirring, transfer them to the pulp storage tank. After continuous stirring and mixing, transfer them to the pulp box. Fix the rotating shaft of the squeezing roller to the output shaft of the external motor. Connect the drain pipe to the negative pressure equipment. The operator starts the active motor and the external motor. The active motor drives the active roller to rotate. The active roller cooperates with the support roller to drive the mesh curtain to wind and transport. The rotation speed of the squeezing roller matches the moving speed of the mesh curtain to prevent relative rubbing from damaging the core material sheet. During the rising process of the mesh curtain, the fibers in the pulp box are evenly dispersed and laid flat on the mesh curtain to form a core material sheet. When the core material sheet passes between the squeezing roller and the negative pressure collection box, the moisture in the core material sheet is squeezed out and the moisture enters the negative pressure collection box through the filter hole on the top of the negative pressure collection box. The negative pressure equipment sucks it through the drain pipe, and the water in the negative pressure collection box is collected and discharged into the drain pipe. As the mesh curtain continues to rise, the core material sheet can be dehydrated. The drying equipment can be connected to the back of the active roller to continuously perform the core material forming and drying operations. 2. A pushing assembly is provided. When the core material sheet is formed by conveying the mesh curtain part, the reciprocating motor is started, and the reciprocating motor drives the double-headed screw to rotate reciprocatingly. The clamping seat and the trapezoidal plate limit the movable plate, so that the two movable plates are close to or away from each other, and the movable plate drives the slide bar and the clamping seat to move. The clamping seat slides inside the trapezoidal plate. The trapezoidal plate is tilted, so that when the movable plate moves, the clamping seat drives the slide bar to slide inside the auxiliary groove, and the slide bar drives the connecting plate to compress the spring 1, and the slide bar drives the oblique push plate to slide. By the mutual approach of the movable plates and the sliding of the oblique push plate, the slurry is slowly pushed to the position of the active roller, so as to keep the fiber content at the feeding position of the mesh curtain part high, thereby facilitating the fiber feeding and paving operation. The movement of the movable plate will also drive the vertical rod to move, and the vertical rod drives the slide cylinder and the connecting rod to move; 3. A paving assembly is provided. The movement of the connecting rod drives the sliding seat and the scraper plate to move. The sliding seat slides on the outside of the guide rod. The limit plate blocks the loading of the fiber, so that the thickness of the core sheet is uniform. The excess fiber is attached to the outside of the limit plate. As the inclined push plates approach and move away from each other, the scraper plate reciprocates to scrape off the fibers attached to the limit plate. The inclined surface of the scraper plate makes it easy for the scraped fibers to fall into the slurry again. At the same time, by starting the auxiliary motor to rotate, the auxiliary motor drives the rotating shaft and the stirring blade to rotate. The stirring blade is used to stir the slurry to facilitate maintaining the slurry. Uniformity improves the uniformity and continuity of the core material sheet flattening. By rotating the adjusting screws on both sides, the adjusting screws drive the bottom plate to rise and fall, and the bottom plate drives the limit plate to rise and fall, which is convenient for adjusting the forming thickness of the core material sheet. The limit plate drives the sliding seat and the connecting rod to rise and fall, and the connecting rod drives the slide to slide on the outside of the vertical rod. The spring 2 assists the sliding of the slide, which solves the problem of relying solely on the transmission of the mesh curtain itself to drive the fiber flattening, which is not convenient for maintaining the uniform laying of the fiber on the mesh curtain, thereby affecting the uniformity of the core material thickness and reducing the forming quality of the core material.

[0035] Example 1: Figure 4-Figure 9 As shown, water and centrifugal cotton are added to the pulp mixing pool and fully soaked, and then transferred to the pulp storage pool after stirring. After continuous stirring and mixing, the pulp is transferred to the pulp box 1. The rotating shaft of the squeezing roller 10 is fixedly installed with the output shaft of the external motor, and the drain pipe 12 is connected to the negative pressure equipment. The operator starts the active motor 4 and the external motor. The active motor 4 drives the active roller 5 to rotate. The active roller 5 cooperates with the support roller 13 to drive the mesh curtain part 6 to wind and transport. The rotation speed of the squeezing roller 10 matches the moving speed of the mesh curtain part 6 to prevent relative rubbing from damaging the core material sheet. During the rising process of the mesh curtain part 6, the fibers in the pulp box 1 are evenly dispersed and spread on the mesh curtain part 6 to form a core material sheet.

[0036] When the core material sheet passes between the squeezing roller 10 and the negative pressure collection box 11, the moisture in the core material sheet is squeezed out and enters the negative pressure collection box 11 through the filter hole on the top of the negative pressure collection box 11. The negative pressure equipment is sucked through the drain pipe 12, and the water in the negative pressure collection box 11 is collected and discharged into the drain pipe 12. As the mesh curtain part 6 continues to rise, the core material sheet can be dehydrated. The rear of the active roller 5 can be connected to the drying equipment to continuously perform the core material forming and drying operations.

[0037] When the mesh curtain part 6 is transported to form the core material sheet, the reciprocating motor 71 is started to work, and the reciprocating motor 71 drives the double-headed screw 72 to rotate back and forth. The clamping seat 76 and the trapezoidal plate 77 limit the movable plate 74, so that the two movable plates 74 are close to or away from each other. The movable plate 74 drives the slide 75 and the clamping seat 76 to move, and the clamping seat 76 slides inside the trapezoidal plate 77. The trapezoidal plate 77 is tilted, so that when the movable plate 74 moves, the clamping seat 76 will drive the slide 75 to slide inside the auxiliary groove 710.

[0038] The slide bar 75 drives the connecting plate 712 to compress the spring 1 711, and the slide bar 75 drives the inclined push plate 79 to slide. By the mutual approach of the movable plates 74 and the sliding of the inclined push plate 79, the slurry is slowly pushed to the position of the active roller 5, and the fiber content at the feeding position of the mesh curtain part 6 is kept high, thereby facilitating the feeding and flattening operation of the fiber. The movement of the movable plate 74 will also drive the vertical rod 713 to move, and the vertical rod 713 drives the slide cylinder 714 and the connecting rod 716 to move.

[0039] A leveling assembly 8 is provided in the middle of the interior of the slurry box 1. The leveling assembly 8 includes a limit plate 87 and a sliding seat 810 symmetrically slidably installed on the top of the limit plate 87. A scraper plate 811 is fixedly connected to one side of the sliding seat 810, and the scraper plate 811 is in contact with the limit plate 87.

[0040] An auxiliary motor 81 is also fixedly installed on the outside of the slurry box 1. The auxiliary motor 81 and the reciprocating motor 71 are located on the same side. The output end of the auxiliary motor 81 passes through the slurry box 1 and is fixedly connected to a rotating shaft 82. The rotating shaft 82 is rotatably connected to the slurry box 1, and the outside of the rotating shaft 82 is evenly fixedly connected with a stirring blade 83.

[0041] The paving assembly 8 also includes two mounting plates 84 symmetrically fixedly mounted on both sides of the inner wall of the slurry box 1. The internal vertical thread of the mounting plate 84 is connected to an adjusting screw 85, the bottom end of the adjusting screw 85 is fixedly connected to a bottom plate 86, a limiting plate 87 is fixedly connected between the two bottom plates 86, and the top of the bottom plate 86 is fixedly connected to an inner plate 88.

[0042] A guide rod 89 is rotatably connected between the two inner plates 88 , and two sliding seats 810 are symmetrically provided. The sliding seats 810 are slidably connected to the guide rod 89 , and one end of the connecting rod 716 away from the slide cylinder 714 is fixedly connected to the sliding seat 810 .

[0043] Example 2: Figure 10-13 As shown, the movement of the connecting rod 716 drives the sliding seat 810 and the scraper plate 811 to move. The sliding seat 810 slides on the outside of the guide rod 89, and the limit plate 87 blocks the loading of the fibers, so that the thickness of the core material sheet is uniform, and the excess fibers are attached to the outside of the limit plate 87. As the inclined push plates 79 approach and move away from each other, the scraper plate 811 moves back and forth to scrape off the fibers attached to the limit plate 87. The inclined surface of the scraper plate 811 makes it easy for the scraped fibers to fall into the slurry again.

[0044] At the same time, by starting the auxiliary motor 81 to rotate, the auxiliary motor 81 drives the rotating shaft 82 and the stirring blade 83 to rotate. The stirring blade 83 is used to stir the slurry, which is convenient for maintaining the uniformity of the slurry and improving the uniformity and continuity of the core material sheet paving. By rotating the adjusting screws 85 on both sides, the adjusting screws 85 drive the bottom plate 86 to rise and fall and adjust, and the bottom plate 86 drives the limit plate 87 to rise and fall and adjust, which is convenient for adapting to the adjustment of the forming thickness of the core material sheet. The limit plate 87 drives the sliding seat 810 and the connecting rod 716 to rise and fall and adjust. The connecting rod 716 drives the slide 714 to slide on the outside of the vertical rod 713. The spring 2 715 assists the sliding of the slide 714, which solves the problem that the fiber is laid flat only by the transmission of the mesh curtain itself, which is not convenient for maintaining the uniform laying of the fiber on the mesh curtain, thereby affecting the uniformity of the core material thickness and reducing the forming quality of the core material.

[0045] Working principle: When using this device, first, Figures 1-13 As shown, water and centrifugal cotton are added to the pulp mixing tank and fully soaked, and then transferred to the pulp storage tank after stirring. After continuous stirring and mixing, the pulp is transferred to the pulp box 1. The rotating shaft of the squeezing roller 10 is fixed to the output shaft of the external motor, and the drain pipe 12 is connected to the negative pressure equipment. The operator starts the active motor 4 and the external motor to work. The fibers in the pulp box 1 are evenly dispersed and laid flat on the mesh curtain part 6 to form a core material sheet. The water in the core material sheet is squeezed out and the water enters the negative pressure collection box 11 through the filter hole on the top of the negative pressure collection box 11. When the mesh curtain part 6 is transported to form a core material sheet, the reciprocating motor 71 is started to work, and the reciprocating motor 71 drives the double-headed screw 72 to rotate back and forth. The mutual proximity of 74 and the sliding of the inclined push plate 79 facilitate the slow pushing of the slurry to the position of the active roller 5. The movement of the movable plate 74 will also drive the movement of the vertical rod 713, and the vertical rod 713 drives the slide 714 and the connecting rod 716 to move. The limit plate 87 blocks the loading of the fiber, so that the thickness of the core material sheet is uniform, and the excess fiber is attached to the outside of the limit plate 87. The inclined surface of the scraper plate 811 facilitates the scraped fiber to fall into the slurry again. The stirring blade 83 is used to stir the slurry. By rotating the adjusting screws 85 on both sides, the adjusting screws 85 drive the bottom plate 86 to rise and fall, and the bottom plate 86 drives the limit plate 87 to rise and fall, so as to adapt to the adjustment of the forming thickness of the core material sheet.
