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.

[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 retracted, 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 application has the following beneficial effects:

[0033] 1、The present application can drive the top bellows to stretch and contract synchronously when the fixed disc stretches and contracts, when the bellows are compressed, the air inside the bellows will be forced into the guide pipe and then into the fixed bin through the connecting pipe, then the gas will enter the top ring through the connecting pipe of the fixed pipe, and then the gas will enter the sliding sleeve, so that the sliding sleeve will stretch and drive the lifting column to descend, when the fixed disc stretches, the bellows will reset under the action of the internal spring, so that the sliding sleeve and the lifting column will contract and reset, so that the lifting column can stretch and contract with the stretching and contraction rhythm of the fixed disc and the rotating disc, realizing the precise synchronization of the lifting column and the feeding rhythm, the lifting column can act as a plunger in the feeding pipe when stretching and contracting, forming a positive pushing force in the feeding pipe, effectively making up for the insufficient driving force of traditional negative pressure suction on high viscosity materials, completely solving the technical pain point of poor discharge of latex and other viscous materials, significantly improving the stability and continuity of material conveying, and facilitating the smooth discharge of viscous materials.

[0034] 2、During the working process, the continuously entering gas can drive the impeller inside the fixed bin to rotate, when the impeller rotates, the magnetic block inside the impeller can cooperate with the magnetic strip inside the lifting column, so that the lifting column can be driven to rotate, by making the lifting column rotate during the lifting process, the movement of the lifting column in the feeding pipe can be facilitated, so that the lifting column can more easily break the material inside the feeding pipe, avoiding the jamming of the lifting column during reciprocating motion, when the lifting column rotates, the fixed rod inside the lifting column can drive the collision ball to rotate synchronously, in this process, the collision ball can continuously contact the side plate on the sliding sleeve, the collision between the collision ball and the side plate can make the sliding sleeve and the lifting column vibrate at high frequency, so that the material agglomeration in the feeding pipe can be efficiently broken, the surrounding material can be more loose, the adhesion of the material to the pipe is reduced, avoiding jamming, so that the auxiliary unloading work of the lifting column can be more smooth, ensuring the long-term stable operation of the feeding system under high viscosity working conditions.

[0035] 3、During the stretching and contraction process of the fixed disc, when the hydraulic rod end stretches and contracts, under the constraint and cooperation of the guide column and the guide groove, the rotating column and the rotating disc will be driven to rotate, when the rotating disc rotates, the top paddle will continuously contact the fixed protrusion inside the fixed disc, so that the paddle will continue to vibrate, the shock wave will be transmitted to the bottom of the rotating disc through the paddle, forming a "rotary shearing + high frequency vibration" double anti-sticking mechanism during the stretching and contraction of the rotating disc for material pumping and discharging, the high speed rotation and vibration of the rotating disc can better separate the material, avoiding material adhesion, which is beneficial to actual use.

[0048] Further, in specific implementation, people can add materials to the preparation device through the feeder, the flange at the end of the feeding pipe 103 can be connected with each raw material conveying pipe, so that each required raw material can be gathered in the shell 102 through the feeding pipe 103 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 stretch and retract, and the fixed disc 112 and the rotating disc 113 at the end can be synchronously moved when the hydraulic rod 111 stretches and retracts, the one-way valve at the bottom of the shell 102 is effective in the contraction process of the fixed disc 112 and the rotating disc 113, a closed space is formed in the shell 102, at this time, the fixed disc 112 and the rotating disc 113 rise to form negative pressure siphon, the one-way valve in the feeding pipe 103 is opened, so that the material in the feeding pipe 103 is extracted into the shell 102, and then when the fixed disc 112 and the rotating disc 113 stretch out, the one-way valve in the feeding pipe 103 is closed to avoid backflow of the material, and the one-way valve at the bottom of the shell 102 is opened to discharge the material in the shell 102, thereby achieving the feeding work.

[0049] Among them, bellows 114 are provided on both sides of the top of the fixed disk 112, and the top of the bellows 114 is fixedly connected to a conduit 110, and the end of the conduit 110 away from the bellows 114 passes through the side wall of the shell 102, and the end of the conduit 110 away from the bellows 114 is fixedly connected to the connecting pipe 104, and both ends of the connecting pipe 104 are fixedly connected to the fixed bin 107, and the guide column 117 passes through the opening 119. A return spring is installed inside the bellows 114, and a plurality of feed pipes 103 are fixedly connected to the lower part of the outer periphery of the shell 102, and a fixed bin 107 is installed on the upper part of the outer periphery of the feed pipe 103. , a fixing frame 123 is provided on the inside of the fixed bin 107, and the outer periphery of the fixing frame 123 is rotatably connected to the impeller 108, and a uniformly distributed connecting pipe 106 is provided on one side of the top of the fixed bin 107, and the top of the connecting pipe 106 is fixedly connected to the top ring 105, and the top ring 105 is installed on the upper part of the outer periphery of the feed pipe 103, and a plurality of fixed pipes 122 are fixedly connected to the inside of the top ring 105, and the bottom of the intersection between the fixed pipes 122 is fixedly connected to the sliding sleeve 125, and the bottom of the sliding sleeve 125 is rotatably connected to the lifting column 124, and the lifting column 124 is arranged inside the feed pipe 103;

[0050] Furthermore, in a specific implementation, when the fixed plate 112 is extended and retracted, the bellows 114 at the top will be driven to extend and retract synchronously. When the bellows 114 is compressed, the air inside the bellows 114 will be forced into the conduit 110 and introduced into the fixed chamber 107 through the connecting pipe 104. Then, the gas will enter the top ring 105 through the connecting pipe 106 at the top of the fixed chamber 107. The gas will enter the sliding sleeve 125 through the connection of the fixed pipe 122, so that the sliding sleeve 125 will extend and drive the lifting column 124 to descend. When the fixed plate 112 is extended and retracted, the air inside the bellows 114 will be forced into the conduit 110 and introduced into the fixed chamber 107 through the connecting pipe 106 at the top of the fixed chamber 107. When the lever 112 is extended, the bellows 114 is reset under the action of the internal spring, thereby driving the sliding sleeve 125 and the lifting column 124 to contract and reset, so that the lifting column 124 can follow the extension and contraction rhythm of the fixed disk 112 and the turntable 113 to extend and retract. When the lifting column 124 is extended and retracted, it acts as a plunger inside the feed pipe 103, thereby assisting in the discharge of materials inside the feed pipe 103, thereby avoiding the situation where the negative pressure of the fixed disk 112 is insufficient to suck the materials when working, resulting in poor discharge, which is conducive to the smooth discharge of viscous materials.

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

[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. By rotating the lifting column 124 during lifting, the movement of the lifting column 124 inside the feeding pipe 103 is facilitated, so that the lifting column 124 can more easily break the material inside the feeding pipe 103, and the lifting column 124 can avoid jamming during reciprocating motion. When the lifting column 124 rotates, the fixed rod 127 inside the lifting column 124 drives the collision ball 129 to rotate synchronously. In this process, the collision ball 129 continuously contacts the side plate 128 on the sliding sleeve 125. The collision between the collision ball 129 and the side plate 128 causes the sliding sleeve 125 and the lifting column 124 to vibrate at a high frequency, so that the surrounding material is more loose, thereby making the auxiliary unloading work of the lifting column 124 more smooth, and facilitating actual use.

[0053] Wherein, the hydraulic rod 111 is provided with openings 119 on the front and back sides of the end, and the end of the hydraulic rod 111 is rotatably connected with a rotating column 116, the rotating column 116 is provided with a plurality of guide grooves 115 on the outer periphery, the guide grooves 115 are slidably connected with guide columns 117 on the inner side of the upper part, the guide columns 117 are fixedly connected to the inner side of the upper part of the shell 102, the rotating column 116 penetrates through the middle part of the fixed disc 112, the rotating column 116 is fixedly connected with a rotating disc 113 at the bottom, the rotating disc 113 is fixedly connected with uniformly distributed push pieces 118 at the top, the fixed disc 112 is provided with a cavity 121 at the bottom, the cavity 121 is fixedly connected with uniformly distributed fixed protrusions 120 at the top, and the fixed protrusions 120 are used to cooperate with the push pieces 118;

[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.

10. A feeding process for preparing a polymer latex for paper capable of high-speed coating, applied to a feeding device for preparing a polymer latex for paper capable of high-speed coating according to any one of claims 1 to 9, characterized in that: The following steps are included: S1. Raw material access and pretreatment: Use the flange at the end of the feed pipe (103) to connect the raw material delivery pipes to ensure that the raw material delivery path is sealed and unobstructed. In this step, the sealing of the feed pipe (103) and the connection parts must be checked in advance to avoid air leakage during subsequent negative pressure suction; S2. Start-up of the driving device and formation of the confined space: The hydraulic cylinder (101) is started to drive the hydraulic rod (111) to perform reciprocating telescopic motion, thereby synchronously driving the fixed disk (112) and the rotating disk (113) at the end to move. When the fixed disk (112) and the rotating disk (113) are retracted, the one-way valve at the bottom of the housing (102) is closed, so that a closed space is formed inside the housing (102), creating conditions for negative pressure siphon feeding; S3, negative pressure siphon feeding: The fixed disk (112) and the rotating disk (113) rise in the closed space, forming a negative pressure siphon effect, which opens the one-way valve in the feed pipe (103). The raw material is sucked from the feed pipe (103) into the interior of the housing (102) under the action of negative pressure. This step utilizes negative pressure to achieve efficient suction of the raw material, which is suitable for the viscosity characteristics of the polymer latex for paper. S4, forward push discharge: When the fixed disk (112) and the rotating disk (113) extend, the one-way valve in the feed pipe (103) automatically closes to prevent the raw material from flowing back; at the same time, the one-way valve at the bottom of the shell (102) opens, and the raw material inside the shell (102) is discharged from the bottom outlet under the action of the positive thrust, completing one feeding cycle; S5. Auxiliary blanking of bellows (114): S5.

1. When the fixed plate (112) expands and contracts, the top bellows (114) is driven to expand and contract synchronously: ① When the bellows (114) is compressed, the internal air is pressed into the conduit (110), introduced into the fixed chamber (107) through the connecting pipe (104), and then enters the sliding sleeve (125) through the connecting pipe (106), the top ring (105) and the fixed pipe (122), pushing the sliding sleeve (125) to extend and driving the lifting column (124) to descend; ② When the fixed plate (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; ③ The lifting column (124) moves in the feed pipe (103) in a plunger-like manner in accordance with the rhythm of the fixed plate (112), thereby assisting in the discharge of the viscous latex and compensating for the poor discharge caused by insufficient negative pressure suction; S6, Pneumatic drive and rotary assisted unloading: The gas continuously entering the fixed chamber (107) drives the impeller (108) to rotate, and the magnetic block inside the impeller (108) cooperates with the magnetic strip (126) inside 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 tube (103), reduce motion jams, and improve feeding efficiency; S7, high frequency vibration of loose materials: S7.

1. When the lifting column (124) rotates, the internal fixed rod (127) drives the collision ball (129) to continuously collide with the side plate (128) on the sliding sleeve (125), generating high-frequency vibration and transmitting it to the surrounding latex, loosening the latex, reducing viscous resistance, and ensuring the fluidity of the raw material required for high-speed coating; S7.

2. When the hydraulic rod (111) is extended or retracted, the rotating column (116) drives the rotating disk (113) to rotate under the cooperation of the guide column (117) and the guide groove (115). The top paddle (118) and the fixed protrusion (120) inside the fixed disk (112) are in continuous contact to generate vibration. The vibration and the rotation work together to prevent the latex from sticking in the housing (102) and ensure uniform and stable discharge.
