Description

Technical Field

[0001] The invention relates to the technical field of sealant protection, and in particular to a sealant anti-solidification device. Background Art

[0002] Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the gap of the configuration to play a sealing role. It has the functions of leak prevention, waterproofing, vibration prevention, sound insulation, and heat insulation. It is usually made of dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber as the base material, combined with inert fillers such as talcum powder, white clay, carbon black, titanium dioxide and asbestos, and then added with plasticizers, solvents, curing agents, accelerators, etc. It can be divided into three categories: elastic sealant, liquid sealing gasket and sealing putty. It is widely used in the sealing of construction, transportation, electronic instruments and parts.

[0003] Under current conditions, sealants are mainly packaged and stored in barrels. However, the existing storage barrels have a simple structure, and often have unreasonable requirements on sealing. In addition, the storage barrels are not equipped with any measures to stimulate the activity of the sealants. As a result, the sealants are very easy to precipitate and solidify when stored, resulting in poor storage effect of the sealants, which causes great inconvenience in the subsequent use of the sealants. In the prior art, there is a sealant anti-solidification device disclosed in publication number CN214242250U, which includes an outer cylinder and a control switch, a control switch is fixedly installed at the lower right corner of the outer cylinder, a feed hopper is fixedly installed at the upper left and upper right corners of the outer cylinder, a servo motor is fixedly installed at the upper inner part of the outer cylinder, a transmission shaft is rotatably connected to the output end below the servo motor, a bottom scraper is fixedly installed at the bottom end of the transmission shaft, a stirring blade is fixedly installed at the outer wall of the transmission shaft, a separation plate is fixedly installed at the outer wall of the transmission shaft, an inner vertical opening of the separation plate is provided with an inner through hole, a separation needle is fixedly installed on the top of the separation plate, a discharge plate is fixedly installed at the upper inner part of the outer cylinder, a discharge hole is provided at the bottom vertical opening of the discharge plate, and mud pumps are fixedly installed at the left and right ends of the outer cylinder. It has a good anti-solidification effect and can fully heat and stir the stored sealant. However, a relatively complex and cumbersome stirring structure is set up inside it, and the sealant itself has a viscous structure. If the stirring structure itself has too much contact with the sealant and there are many complex components, it will increase the difficulty of cleaning the sealant, and the stirring degree of the sealant cannot be guaranteed. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 6 A sealant anti-solidification device comprises a body 1 with an upper cavity and a lower cavity, a feed port 2 communicating with the upper cavity and a discharge port 3 communicating with the lower cavity are provided in the body 1, it should be noted that both the feed port 2 and the discharge port 3 can be opened and closed, and a drive motor 4 is fixedly mounted on the body 1, the drive motor 4 adopts a servo motor of model HC-SFS81B, and the body 1 is provided with a crushing shaft 5 and a crank shaft 6 of an integrated structure directly driven to rotate by the drive motor 4 through the lower cavity, for further explanation, please refer to the attached manual for details. Figure 1 With the instruction manual Figure 4 , the crushing shaft 5 and the crank shaft 6 are horizontally rotatably installed in the machine body 1, the crank shaft 6 is located at the middle end, the crushing shaft 5 is located at the two end positions, and it extends to the outside of the machine body 1;

[0026] Please refer to the instruction manual for details Figure 1 The pressure booster 12 is designed according to the shape and structure of the upper cavity and is a hollow structure. It utilizes its lifting movement to contact the upper cavity, thereby pressurizing the sealant to maintain the active strength of the sealant.

[0027] The machine body 1 is provided with a transmission shaft 7 corresponding to the upper cavity and connected to the crushing shaft 5. The transmission shaft 7 is horizontally rotatably mounted outside the machine body 1. A pulley 28 is connected between the crushing shaft 5 and the transmission shaft 7. Under the transmission action of the pulley 28, the transmission shaft 7 and the crushing shaft 5 can perform synchronous rotational motion.

[0028] The machine body 1 is provided with a pre-treatment mechanism located in the upper cavity through the transmission shaft 7, and the sealant can be initially stirred in the upper cavity through the pre-treatment mechanism. The machine body 1 is provided with a deep treatment mechanism located in the lower cavity through the crank shaft 6, and the sealant can be cut and stirred in the lower cavity through the deep treatment mechanism, and sieved to ensure uniform discharge.

[0029] The upper cavity and the lower cavity are opened from top to bottom in the body 1, and a material passing through hole 19 connecting the upper cavity and the lower cavity is opened in the middle of the body 1. Because the two are opened from top to bottom, the sealant can achieve directional movement under the action of gravity, which can reduce the driving equipment for the sealant in the body 1.

[0030] The technical points to note are:

[0031] First, the pretreatment mechanism includes a booster cam 8 connected to the transmission shaft 7 by a key, the booster cam 8 is eccentrically arranged, and a lifting frame 10 is movably installed on the body 1 to slide against the booster cam 8. Under the gravity of the booster cam 8 and the lifting frame 10, the booster 12 can be repeatedly lifted and lowered in the upper cavity. A ventilation pipe 11 is integrally arranged in the lifting frame 10, and the booster 12 located in the upper cavity is fixedly mounted on the ventilation pipe 11, and an air inlet 13, a one-way valve 14 and an air outlet 15 are sequentially arranged on the ventilation pipe 11. The one-way valve 14 allows the air in the ventilation pipe 11 to flow in only from top to bottom, and under the action of the booster piston 16, the air can only be discharged through the air outlet 15. A booster piston 16 is fixedly arranged in the cavity and is slidably sleeved in the ventilation pipe 11. A stirring shaft 17 is rotatably mounted on the booster 12, and a driven wind wheel 18 corresponding to the air outlet 15 is keyed on the stirring shaft 17. With reference to the drawings in the specification, it can be seen that a one-way pipe connected to the air outlet 15 is opened in the booster 12, so that the directionally discharged air can drive the driven wind wheel 18, and then drive the stirring shaft 17 to rotate, thereby preliminarily stirring the sealant entering the upper cavity. A feeding rod 20 corresponding to the feeding through hole 19 is integrally connected to the lower end of the booster 12. The feeding rod 20 penetrates into the feeding through hole 19, and can further pressurize the sealant, forcing the sealant to enter the lower cavity.

[0032] The outer wall of the machine body 1 is provided with a first guide slot 9 which is slidably sleeved with a lifting frame 10 , and the ventilation duct 11 longitudinally slides through the top of the machine body 1 and extends into the upper cavity to guide and limit the ventilation duct 11 and the supercharging member 12 .

[0033] Second, the deep processing mechanism includes an automatic telescopic rod 21 and a material receiving mesh plate 22 installed with a pin in the lower cavity, and a connecting sleeve 23 is rotatably mounted on the crank shaft 6, and a traction link 24 is connected to the connecting sleeve 23 with a pin. A movable filter 27 movably pulled by the traction link 24 is movably arranged in the lower cavity. Because the crank shaft 6 generates a height difference during rotation, the direction is adjusted by the connecting sleeve 23 and the traction link 24, so that the movable filter 27 can be lifted and lowered in the vertical direction in the lower cavity.

[0034] The material receiving mesh plate 22 is correspondingly arranged at a position below the material passing through hole 19, and the output end of the automatic telescopic rod 21 is pin-connected to the material receiving mesh plate 22. The automatic telescopic rod 21 adopts an electric telescopic device with model CAHB-10. A second guide groove 25 is provided on the inner wall of the lower cavity, and a reset spring 26 fixedly connected to the mobile filter 27 is welded in the second guide groove 25. The elastic support and traction of the reset spring 26 can improve the stability of the up and down movement of the mobile filter 27, thereby avoiding large-scale splashing of the sealant caused by a large jump of the mobile filter 27.

[0035] The present invention can be explained by the following operation mode:

[0036] The sealant is poured into the upper cavity of the machine body 1 through the feed port 2, and the drive motor 4 is controlled to start;

[0037] The output end of the driving motor 4 drives the integrated crushing shaft 5 and the crank shaft 6 to rotate, and the crushing shaft 5 drives the transmission shaft 7 to rotate synchronously through the pulley 28, and the transmission shaft 7 drives the booster cam 8 to rotate, and the booster cam 8 squeezes the lifting frame 10, so that it moves up and down guided by the first guide slot 9;

[0038] The lifting frame 10 drives the supercharging member 12 to move up and down in the upper cavity through the ventilation duct 11, and the gas enters the ventilation duct 11 through the air inlet 13. Due to the relative movement of the supercharging piston 16, the air in the ventilation duct 11 is discharged from the ventilation duct 11 through the air outlet 15, so as to drive the driven wind wheel 18, so that the stirring shaft 17 rotates horizontally on the supercharging member 12, so as to stir the sealant entering the upper cavity;

[0039] When the downwardly moved booster 12 moves down to the lowest height position, it squeezes the sealant by contacting with the upper cavity, so that the further squeezed sealant enters the feed through hole 19. Because the feed rod 20 penetrates into the feed through hole 19, the sealant enters the lower cavity.

[0040] The sealant moves to the receiving mesh plate 22. Because the automatic telescopic rod 21 pulls the receiving mesh plate 22, the receiving mesh plate 22 tilts repeatedly, accelerating the receiving and discharging of the sealant, so that it enters the lower cavity evenly. Because the crushing shaft 5 further cuts and stirs it, the sealant moves to the mobile filter screen 27.

[0041] The rotation of the crank shaft 6 causes the traction link 24 to move up and down, thereby traction of the movable filter screen 27, thereby accelerating the screening of the sealant and discharging it out of the machine body 1 through the discharge port 3.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
