Description

TECHNICAL FIELD

[0001] The application relates to a feeding device for preparing paper polymer latex capable of high-speed coating and a process. BACKGROUND

[0002] In the preparation process of paper polymer latex, the stability of the feeding system directly affects the quality of the subsequent coating process. Traditional feeding devices mostly rely on single negative pressure suction or mechanical pushing mode, and have poor adaptability to high-viscosity latex materials. When driven by negative pressure, the suction force is easily insufficient due to excessive viscosity resistance of the materials, resulting in material breakage or flow fluctuation. Mechanical pushing often causes transportation jam or residual pollution due to the adhesion of materials to the inner wall of the pipeline. Meanwhile, the existing equipment lacks a dynamic processing mechanism for viscous materials. Latex is easily formed into agglomerates during the transportation process, which not only affects the accuracy of the proportioning, but also causes the maintenance frequency to increase due to the adhesion of the equipment parts. With the increasing requirements of high-speed coating technology on the continuity and stability of raw material supply, the traditional feeding device has been difficult to meet the production requirements of high viscosity, high precision and high efficiency. Therefore, the application provides a feeding device for preparing paper polymer latex capable of high-speed coating and a process, which is used to solve the above-mentioned problems. SUMMARY

[0012] Preferably, the guide column penetrates the opening, and a reset spring is installed in the inside of the corrugated pipe.

[0013] Preferably, a feeding process for preparing a paper polymer latex capable of high-speed coating comprises the following operation steps.

[0014] S1, raw material access and pretreatment:

[0015] The flange plate at the end of the feeding pipe is connected with each raw material conveying pipeline to ensure that the raw material conveying path is sealed and smooth. The sealing property of the feeding pipe and the connection part needs to be checked in advance to avoid air leakage during subsequent negative pressure suction.

[0016] S2, driving device starts and forms a sealed space:

[0017] The hydraulic cylinder is started to drive the hydraulic rod to make reciprocating extension and retraction movement, and the fixed disc and the rotating disc at the end are synchronously moved. When the fixed disc and the rotating disc are contracted, the one-way valve at the bottom of the shell is closed, so that a sealed space is formed in the shell to create conditions for negative pressure siphon feeding.

[0018] S3, negative pressure siphon feeding:

[0019] The fixed disc and the rotating disc rise in the closed space to form a negative pressure siphon effect, open the one-way valve in the feeding pipe, and suck the raw materials from the feeding pipe into the shell under the action of negative pressure. This step uses negative pressure to realize efficient suction of the raw materials, which is suitable for the viscous characteristics of the polymer latex for paper;

[0020] S4, forward pushing and discharging:

[0021] When the fixed disc and the rotating disc are extended, the one-way valve in the feeding pipe is automatically closed to prevent backflow of the raw materials. At the same time, the one-way valve at the bottom of the shell is opened, and the raw materials in the shell are discharged from the bottom discharge port under the action of the forward pushing force, completing a feeding cycle;

[0022] S5, auxiliary discharging by corrugated pipe:

[0023] S5.1, the fixed disc stretches and contracts to drive the top corrugated pipe to stretch and contract synchronously:

[0024] ① When the corrugated pipe is compressed, the internal air is pressed into the guide pipe, guided into the fixed bin through the communication pipe, and then enters the sliding sleeve through the connecting pipe, the top ring and the fixed pipe, pushes the sliding sleeve to stretch, and drives the lifting column to descend;

[0025] ② When the fixed disc stretches, the corrugated pipe resets under the action of the internal spring, and the sliding sleeve and the lifting column contract and reset;

[0026] ③ The lifting column moves as a plunger in the feeding pipe in coordination with the fixed disc, which assists in guiding the viscous latex out and makes up for the insufficient discharge caused by negative pressure suction;

[0027] S6, pneumatic driving and rotary auxiliary discharging:

[0028] The gas continuously entering the fixed bin drives the impeller to rotate, and the inner magnetic block of the impeller cooperates with the inner magnetic strip of the lifting column to drive the lifting column to rotate synchronously during the lifting process. The rotating lifting column can easily break the latex agglomerates in the feeding pipe, reduce the movement jamming, and improve the discharging efficiency;

[0029] S7, high-frequency vibration to loosen the materials:

[0030] S7.1, when the lifting column rotates, the internal fixed rod drives the impact ball to continuously collide with the side plate on the sliding sleeve, generating high-frequency vibration and transmitting it to the surrounding latex, loosening the latex, reducing the viscous resistance, and ensuring the flowability of the raw materials required for high-speed coating;

[0031] S7.2, when the hydraulic rod stretches and contracts, the rotating column drives the rotating disc to rotate under the cooperation of the guide column and the guide groove, and the top paddle continuously contacts the fixed convex block inside the fixed disc to generate vibration. The vibration and rotation jointly act to avoid the adhesion of the latex in the shell and ensure uniform and stable discharging.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In this invention, the expansion and contraction of the fixed disc causes the corrugated pipe at the top to expand and contract synchronously. When the corrugated pipe is compressed, the air inside the corrugated pipe is forced into the conduit and introduced into the fixed chamber through the connecting pipe. Then, the gas enters the top ring through the connecting pipe at the top of the fixed chamber. Through the connection of the fixed pipe, the gas enters the sliding sleeve, causing the sliding sleeve to extend and drive the lifting column to descend. When the fixed disc extends, the corrugated pipe will reset under the action of the internal spring, thereby causing the sliding sleeve and the lifting column to retract and reset. This allows the lifting column to expand and contract in sync with the expansion and contraction rhythm of the fixed disc and the turntable, achieving precise synchronization between the lifting column and the feeding rhythm. When the lifting column expands and contracts, it acts as a plunger inside the feed pipe, generating an active pushing force inside the feed pipe. This effectively compensates for the insufficient driving force of traditional negative pressure suction for highly viscous materials, completely solving the technical pain point of poor discharge of viscous raw materials such as latex, significantly improving the stability and continuity of material conveying, and facilitating the smooth discharge of viscous materials.

[0034] 2. During operation, the continuously supplied gas drives the impeller inside the fixed chamber to rotate. As the impeller rotates, the magnetic block inside the impeller engages with the magnetic strip inside the lifting column, causing the lifting column to rotate as well. This rotation facilitates the movement of the lifting column within the feed pipe, allowing it to more easily break up the material inside and preventing jamming during reciprocating motion. When the lifting column rotates, the fixed rod inside drives the collision ball to rotate synchronously. During this process, the collision ball continuously contacts the side plate on the sliding sleeve. The collision between the collision ball and the side plate causes high-frequency vibrations in both the sliding sleeve and the lifting column, effectively breaking up material agglomerates within the feed pipe. This loosens the surrounding material, reduces its adhesion to the pipe, and prevents jamming, ensuring smoother auxiliary feeding operations and long-term stable operation of the feeding system under high-viscosity conditions.

[0035] 3. During the extension and retraction of the fixed disc, when the end of the hydraulic rod extends and retracts, the guide column and the turntable are driven to rotate under the constraint and cooperation of the guide column and the guide groove. When the turntable rotates, the top paddle will continuously contact the fixed protrusion on the inner side of the fixed disc, causing the paddle to continue to vibrate. The shock wave will be transmitted to the bottom of the turntable through the paddle. During the material extraction and discharge process of the turntable extension and retraction, a dual anti-sticking mechanism of "rotational shearing + high-frequency vibration separation" is formed. The high-speed rotation and vibration of the turntable can better separate the material and avoid material adhesion, which is beneficial to practical use. Attached Figure Description

[0049] The top of the fixed disc 112 is provided with corrugated pipes 114 on both sides, the corrugated pipes 114 are fixedly connected with guide pipes 110 at the top, one end of the guide pipe 110 away from the corrugated pipe 114 penetrates the side wall of the shell 102, the other end of the guide pipe 110 away from the corrugated pipe 114 is fixedly connected with a communication pipe 104, the communication pipe 104 is fixedly connected with a fixed bin 107 at both ends, the guide column 117 penetrates the opening 119, the corrugated pipe 114 is internally provided with a return spring, a plurality of feed pipes 103 are fixedly connected to the lower part of the outer periphery of the shell 102, the fixed bin 107 is internally provided with a fixed frame 123, the fixed frame 123 is rotatably connected with an impeller 108 on the outer periphery, the fixed bin 107 is provided with uniformly distributed connecting pipes 106 on one side of the top, the connecting pipe 106 is fixedly connected with a top ring 105 at the top, the top ring 105 is mounted on the upper part of the outer periphery of the feed pipe 103, a plurality of fixed pipes 122 are fixedly connected to the inner side of the top ring 105, the intersection between the fixed pipes 122 is fixedly connected with a sliding sleeve 125 at the bottom, the sliding sleeve 125 is rotatably connected with a lifting column 124 at the bottom, and the lifting column 124 is arranged in the feed pipe 103;

[0050] Further, in specific implementation, when the fixed disc 112 is stretched, the corrugated pipe 114 at the top is synchronously stretched, when the corrugated pipe 114 is compressed, the air in the corrugated pipe 114 is forced into the guide pipe 110 and is guided into the fixed bin 107 through the communication pipe 104, then the gas enters the top ring 105 through the connecting pipe 106 at the top of the fixed bin 107, the communication of the fixed pipe 122 makes the gas enter the sliding sleeve 125, so that the sliding sleeve 125 is stretched, and the lifting column 124 is lowered, when the fixed disc 112 is stretched, the corrugated pipe 114 is reset under the action of the internal spring, so that the sliding sleeve 125 and the lifting column 124 are contracted and reset, so that the lifting column 124 can stretch and contract with the stretching and contraction rhythm of the fixed disc 112 and the rotating disc 113, when the lifting column 124 stretches and contracts, it acts as a plunger in the feed pipe 103, so that it can assist the material in the feed pipe 103 to be guided out, so that the situation that the material is not smoothly guided out due to insufficient suction force of the negative pressure of the fixed disc 112 during work can be avoided, and the viscous material can be smoothly guided out.

[0051] The inner side of the impeller 108 is embedded with uniformly distributed magnetic blocks, the fixed frame 123 is fixedly connected to the upper part of the outer periphery of the feed pipe 103, the fixed frame 123 and the impeller 108 are arranged on the inner side of the fixed bin 107, the inner side wall of the lifting column 124 is embedded with uniformly distributed magnetic strips 126, the inner side wall of the lifting column 124 is fixedly connected with uniformly distributed fixed rods 127 at the upper part, the fixed rod 127 is fixedly connected with a collision ball 129 at the bottom, and the outer periphery of the sliding sleeve 125 is fixedly connected with uniformly distributed side plates 128 at the lower part;

[0052] Further, in actual implementation, in the working process, the impeller 108 inside the fixed bin 107 is driven to rotate by the continuously entering gas, and when the impeller 108 rotates, the magnetic blocks inside the impeller 108 cooperate with the magnetic strips inside the lifting column 124, thereby driving the lifting column 124 to rotate.

[0054] Further, in actual implementation, in the process of driving the fixed disc 112 to stretch and retract, when the end of the hydraulic rod 111 stretches and retracts, the rotating column 116 and the rotating disc 113 are driven to rotate under the constraint and cooperation of the guide column 117 and the guide groove 115. When the rotating disc 113 rotates, the top push piece 118 continuously contacts the fixed protrusion 120 inside the fixed disc 112, so that the push piece 118 continues to vibrate, and the shock wave is transmitted to the bottom of the rotating disc 113 through the push piece 118. In the process of stretching and retracting of the rotating disc 113 for material extraction and discharge, the high-speed rotation and vibration of the rotating disc 113 can better separate the material, avoid material adhesion, and facilitate actual use.

[0055] A feeding process for preparing a paper polymer latex capable of high-speed coating, comprising the following operation steps:

[0056] S1, raw material access and pretreatment:

[0057] The flange at the end of the feed pipe 103 is connected to each raw material conveying pipeline to ensure the sealing and smoothness of the raw material conveying path. The sealing of the feed pipe 103 and the connection part should be checked in advance to avoid air leakage during subsequent negative pressure suction;

[0058] S2, the driving device is started and a sealed space is formed:

[0059] The hydraulic cylinder 101 is started, driving the hydraulic rod 111 to make reciprocating extension and retraction movement, synchronously driving the fixed disc 112 and the rotating disc 113 at the end to move. When the fixed disc 112 and the rotating disc 113 are retracted, the one-way valve at the bottom of the shell 102 is closed, so that a sealed space is formed inside the shell 102, creating conditions for negative pressure siphon feeding;

[0060] S3, negative pressure siphon feeding:

[0061] The fixed disc 112 and the rotating disc 113 rise in the sealed space, forming a negative pressure siphon effect, opening the one-way valve in the feed pipe 103, and the raw materials are sucked into the inside of the shell 102 under the action of negative pressure. This step uses negative pressure to realize efficient suction of the raw materials, which is suitable for the viscous characteristics of paper polymer latex;

[0062] S4, forward pushing and discharging:

[0063] When the fixed disc 112 and the rotating disc 113 are extended, the one-way valve in the feed pipe 103 is automatically closed to prevent backflow of the raw materials. At the same time, the one-way valve at the bottom of the shell 102 is opened, and the raw materials in the shell 102 are discharged from the bottom discharge port under the action of the forward pushing force, completing a feeding cycle;

[0064] S5, bellows 114 auxiliary discharging:

[0065] S5.1, the fixed disc 112 drives the top bellows 114 to extend and retract synchronously:

[0066] ① When the bellows 114 is compressed, the internal air is compressed into the conduit 110, guided into the fixed bin 107 through the communication pipe 104, then enters the sliding sleeve 125 through the connecting pipe 106, the top ring 105 and the fixed pipe 122, pushes the sliding sleeve 125 to extend, and drives the lifting column 124 to descend;

[0067] ② When the fixed disc 112 is extended, the bellows 114 is reset under the action of the internal spring, and the sliding sleeve 125 and the lifting column 124 are retracted and reset;

[0068] ③ The lifting column 124 moves as a plunger with the fixed disc 112 in the feed pipe 103, assisting the viscous latex to be discharged, and making up for the insufficient discharge caused by negative pressure suction;

[0069] S6, pneumatic driving and rotary auxiliary discharging:

[0070] The gas continuously entering the fixed bin 107 drives the impeller 108 to rotate. The inner magnetic block of the impeller 108 cooperates with the inner magnetic strip of the lifting column 124 to drive the lifting column 124 to rotate synchronously during the lifting process. The rotating lifting column 124 can easily break the latex agglomerates in the feeding pipe 103, reduce the movement jam, and improve the discharging efficiency;

[0071] S7, high-frequency vibration to loosen the material:

[0072] S7.1, when the lifting column 124 rotates, the inner fixed rod 127 drives the impact ball 129 to continuously collide with the side plate 128 on the sliding sleeve 125, generating high-frequency vibration and transmitting to the surrounding latex, loosening the latex and reducing the viscous resistance, ensuring the flowability of the raw material required for high-speed coating;

[0073] S7.2, when the hydraulic rod 111 extends and retracts, the rotating column 116 drives the rotating disc 113 to rotate under the cooperation of the guide column 117 and the guide groove 115. The top tab 118 continuously contacts the inner fixed protrusion 120 of the fixed disc 112 to generate vibration. The vibration and rotation jointly act to avoid the adhesion of the latex in the shell 102, and ensure the uniform and stable discharging.

[0074] Working principle:

[0075] In actual use, people can add materials to the preparation device through the feeder, and the flange at the end of the feed pipe 103 can be connected to the raw material conveying pipeline, so that the required raw materials can be gathered through the feed pipe 103 into the shell 102, and discharged through the discharge port at the bottom of the shell 102. The work of the hydraulic cylinder 101 can drive the hydraulic rod 111 to extend and retract, and when the hydraulic rod 111 extends and retracts, the fixed disc 112 and the rotating disc 113 at the end will move synchronously. During the contraction of the fixed disc 112 and the rotating disc 113, the one-way valve at the bottom of the shell 102 is effective, and a closed space is formed in the shell 102. At this time, the fixed disc 112 and the rotating disc 113 rise to form a negative pressure siphon, which opens the one-way valve in the feed pipe 103, so that the material in the feed pipe 103 is extracted into the shell 102. After that, when the fixed disc 112 and the rotating disc 113 extend, the one-way valve in the feed pipe 103 will be closed to avoid backflow of the material, and the one-way valve at the bottom of the shell 102 will be opened to discharge the material in the shell 102, realizing the feeding work. In this process, when the fixed disc 112 extends and retracts, the top corrugated pipe 114 will extend and retract synchronously. When the corrugated pipe 114 is compressed, the air in the corrugated pipe 114 will be forced into the conduit 110 and guided into the fixed bin 107 by the connecting pipe 104. Then the gas enters the top ring 105 through the connecting pipe 106 at the top of the fixed bin 107, and through the connection of the fixed pipe 122, the gas enters the sliding sleeve 125, so that the sliding sleeve 125 extends and drives the lifting column 124 to descend. When the fixed disc 112 extends, the corrugated pipe 114 will reset under the action of the internal spring, so as to drive the sliding sleeve 125 and the lifting column 124 to reset, so that the lifting column 124 can follow the extension and retraction rhythm of the fixed disc 112 and the rotating disc 113. When the lifting column 124 extends and retracts, it will act as a plunger in the feed pipe 103, so as to assist the discharge of the material in the feed pipe 103, thereby avoiding the situation that the suction force of the material is not enough due to the negative pressure when the fixed disc 112 works, which leads to poor discharge. It is beneficial to the smooth discharge of viscous materials. In the working process, the continuously entering gas drives the impeller 108 in the fixed bin 107 to rotate. When the impeller 108 rotates, the magnetic block on the inner side of the impeller 108 cooperates with the magnetic strip on the inner side of the lifting column 124, so as to drive the lifting column 124 to rotate. By making the lifting column 124 rotate during lifting, it is beneficial to the movement of the lifting column 124 in the feed pipe 103, so that the lifting column 124 can more easily break the material in the feed pipe 103. Avoid jamming during reciprocating motion. When the lifting column 124 rotates, the fixed rod 127 in the lifting column 124 drives the collision ball 129 to rotate synchronously. In this process, the collision ball 129 will continuously contact the side plate 128 on the sliding sleeve 125,The collision between the collision ball 129 and the side plate 128 can cause high-frequency vibration of the sliding sleeve 125 and the lifting column 124, so that the surrounding materials can be more loose, so that the auxiliary unloading work of the lifting column 124 can be more smooth, and the actual use is beneficial. During the telescopic process of the fixing disc 112, when the hydraulic rod 111 is telescoped, under the constraint and cooperation of the guide column 117 and the guide groove 115, the rotating column 116 and the rotating disc 113 are driven to rotate. When the rotating disc 113 rotates, the top of the paddle 118 will be in continuous contact with the fixed lug 120 inside the fixing disc 112, so that the paddle 118 will continue to vibrate, and the vibration wave will be transmitted to the bottom of the rotating disc 113 through the paddle 118. During the telescopic process of the rotating disc 113, the high-speed rotation and vibration of the rotating disc 113 can better separate the materials, avoid material adhesion, and be beneficial to actual use.
