Description

TECHNICAL FIELD

[0001] The application relates to the production technology of silicone sealant, in particular to a silicone sealant processing equipment for photovoltaic and a processing technology thereof. BACKGROUND

[0002] In the production and processing of silicone sealant, a plurality of raw materials need to be put into a vacuum kneader, and the raw materials are mixed uniformly by a stirring paddle arranged in a "Z" shape. When the kneader works, the motor drives the driving paddle through the speed reducer, and the driven paddle is driven through the gear. The spiral blades of the stirring paddle axially extrude the raw materials, and the spiral blades also extrude the raw materials radially. The raw materials are subjected to high-speed extrusion and low-speed extrusion, and are subjected to extrusion and separation. The raw materials are fully kneaded, rubbed, mixed and blended, and the physical and chemical reactions of the raw materials are accelerated. In order to ensure that no air bubbles are generated in the stirring and kneading process of the raw materials, the product is compact, and the vacuum is extracted during the kneading of the raw materials to improve the stirring quality of the raw materials. Because of the properties of the silicone sealant, no raw material is adhered and remained in the area of the inner wall of the kneader that can be contacted by the material mass after the kneading of the raw materials is completed. Therefore, after the kneading is completed, the complete discharge is performed by the screw rod inserted into the bottom end of the inside of the kneader and the stirring paddle.

[0003] During the kneading process, the volume of the raw materials before kneading is usually larger than the volume of the uniform material mass after kneading. Therefore, the height of the original raw materials adhered to the top edge of the inner wall of the kneader in the initial stage of kneading is higher than the height of the material mass when the kneading is about to be completed. As a result, the viscous material that is not completely kneaded is adhered to the relatively high inner wall surface during the kneading process. Because the stirring paddle rotating in the axial direction cannot scrape the flat inner wall, the material adhered to the upper part of the inner wall of the kneader is difficult to discharge during the discharge, and the material forms a lump after cooling and is more difficult to remove.

[0032] Please refer to Figure 2 , the rotating plate 52 is connected with an elastic contraction belt 54 below the fixed plate 51, which pulls the rotating plate 52 towards the repositioning assembly 6, when the sliding sleeve box 4 moves upward relative to the fixed block 3, the contraction belt 54 pulls the rotating plate 52, so that the scraper 53 moves away from the inner wall of the kneading body 1, the contraction belt 54 pulls the rotating plate 52 to abut against the side surface of the repositioning assembly 6, thereby controlling the vibration of the scraper 53 and the rotating plate 52 to be slight vibration, avoiding the vibration amplitude being too large, and improving the stability of the action process, when the material is discharged, the vacuum inside the kneading body 1 is released, so that the sliding sleeve box 4 moves upward with the scraping assembly 5, and the upward movement of the scraping assembly 5 increases the distance between the scraping assembly 5 and the repositioning assembly 6, so that the rotating plate 52 rotates downward, and the scraper 53 moves towards the middle part of the kneading body 1, thereby pushing the edge of the material mass outside the stirring paddle 2 to move towards the middle part of the kneading body 1, facilitating the discharging process at the bottom end of the inner side of the kneading body 1.

[0033] Please refer to Figure 2 and Figure 3 The side of the fixed plate 51 facing the abutting assembly 6 is connected with a fixed tooth 55 below the contraction belt 54, the fixed tooth 55 is rounded tooth-shaped towards the side of the abutting assembly 6, when the sliding sleeve box 4 is lowered to the lowest position relative to the fixed block 3, the end of the abutting plate 62 is abutted between the fixed tooth 55 on the side of the rotating plate 52 and below the contraction belt 54, the end of the abutting plate 62 is rounded, and the end of the abutting plate 62 is always close to the inner wall of the rotating plate 52 and is relatively slidingly connected, and an obtuse angle opening upward is formed between the straight line where the abutting plate 62 and the supporting plate 61 are located, and the rotating plate 52 is moved downward, so that the rotating plate 52 pushes the abutting plate 62 to reach the maximum angle controlled by the elastic belt 63, the side of the rotating plate 52 moves a greater length relative to the end of the abutting plate 62, so that the fixed tooth 55 on the side of the rotating plate 52 contacts the end of the abutting plate 62, and through the shape of the fixed tooth 55, the abutting plate 62 moves relative to the fixed tooth 55, which causes the rotating plate 52 to vibrate, the scraper 53 is driven by the rotating plate 52 to vibrate, the scraper 53 can shake off and scrape off the impurities on the inner wall of the kneader body 1, the scraped material quickly returns to the inside of the material mass, which facilitates the rapid and uniform scraping of the material from the inner wall of the kneader body 1 and reduces the waste of the material.

[0035] S1, put 107 glue 9# base material, fumed silica, C03, C04 and 996# ag into the kneader body 1, vacuumize the inside of the kneader body 1, start the motor assembly 9 driving the stirring paddles 2 when the inside of the kneader body 1 reaches the required vacuum pressure value for kneading, and make the two stirring paddles 2 rotate at different speeds to knead the material;

[0036] S2, when the two stirring paddles 2 pull the material apart from both sides at the top end of the inside of the kneader body 1, the height of the material in the middle of the kneader body 1 is the lowest at this time, so that the top end of the material no longer presses the sliding sleeve box 4, the sliding sleeve box 4 moves downward, the sliding sleeve box 4 drives the scraping assembly 5 to move, the side of the rotating plate 52 abuts against the end of the abutting plate 62 and moves downward relative to the abutting plate 62, the abutting plate 62 is rotated downward by the movement of the rotating plate 52 and the elastic force of the elastic belt 63, the side of the scraper 53 driven by the rotating plate 52 abuts against the inner wall of the kneader body 1 and moves downward, and the inner wall of the kneader body 1 is scraped;

[0037] S3, when the two stirring paddles 2 extrude the material together at the top end of the kneader body 1, the material reaches the highest height in the middle of the kneader body 1, so that the top end of the material extrudes the sliding sleeve box 4 to move upward, that is, the sliding sleeve box 4 drives the scraping assembly 5 to move, so that the side of the rotating plate 52 abuts against the end of the abutting plate 62 and moves upward relative to the abutting plate 62, the abutting plate 62 is rotated upward by the movement of the rotating plate 52 and the elastic force of the elastic belt 63, so that the side of the scraping plate 53 driven by the rotating plate 52 moves upward away from the inner wall of the kneader body 1;

[0038] S4, when the material kneading is completed, the screw is inserted into the inside of the discharge pipe 8 from the discharge port on one side, the screw is driven to rotate and cooperate with the rotation of the stirring paddle 2, so that the material is discharged through the discharge pipe 8.

[0039] The use method (working principle) of the present application is as follows:

[0040] After the material is put into the kneader body 1 from the feeding port, the upper cover 11 and the shell 12 are closed, the inside of the kneader body 1 is vacuumized, the inside area of the fixed block 3 and the sliding sleeve box 4 is lowered due to the decrease of the outside air pressure, so that the sliding sleeve box 4 moves downward relative to the fixed block 3, the bottom end surface of the sliding sleeve box 4 is closer to the material in the inside of the kneader body 1, and the air bag in the inside of the fixed block 3 and the sliding sleeve box 4 is pulled, so that the air bag is vertically stretched to compress the inside gas, the inside gas of the air bag enters the inside of the sealed air bag 72 through the air pipe 71, the outside of the sealed air bag 72 abuts against the circumferential contact surface of the upper cover 11 and the shell 12, the sealing strength is improved, the inside of the kneader body 1 reaches the required vacuum pressure value for kneading, the motor assembly 9 driving the stirring paddle 2 is started, the stirring paddle 2 rotates in the inside of the kneader body 1, and the two stirring paddles 2 differentially rotate to knead the material.

[0041] When the two stirring paddles 2 extrude the material together at the top end of the kneader body 1, the material reaches the highest height in the middle of the kneader body 1, so that the top end of the material abuts against the bottom end surface of the sliding sleeve box 4 and pushes the sliding sleeve box 4 to move upward, the upward movement of the sliding sleeve box 4 drives the connected scraping assembly 5 to move upward, so that the side of the rotating plate 52 abuts against the end of the abutting plate 62 and moves upward relative to the abutting plate 62, the abutting plate 62 is rotated upward by the friction of the rotating plate 52 and the elastic force of the elastic belt 63, the upward rotation of the abutting plate 62 reduces the distance between the end of the abutting plate 62 and the side of the scraping plate 53, so that the rotating plate 52 moves to the direction of the abutting assembly 6 due to the rotation of the abutting plate 62 and the elastic force of the contraction belt 54, the side of the scraping plate 53 driven by the rotating plate 52 moves upward away from the inner wall of the kneader body 1, and in the movement of the rotating plate 52, the fixed teeth 55 on the side of the rotating plate 52 gradually contact the end of the abutting plate 62, so that the rotating plate 52 drives the scraping plate 53 to vibrate as a whole due to the shape of the fixed teeth 55, so that the scraping plate 53 shakes off the raw materials attached to the surface of the scraping plate 53.

[0042] When the material against the bottom end of the sliding sleeve box 4 is driven to rotate by the two stirring paddles 2 and then to the bottom end of the kneader body 1, the sliding sleeve box 4 will move downward again due to its own gravity, that is, the sliding sleeve box 4 will drive the scraping assembly 5 to move downward, so that the side of the rotating plate 52 abuts against the end of the abutting plate 62 and moves downward relative to the abutting plate 62, causing the fixed teeth 55 and the abutting plate 62 to interact again due to the shape of the fixed teeth 55, so that the rotating plate 52 vibrates and drives the scraper 53 to vibrate. When the rotating plate 52 abutting against the end of the abutting plate 62 moves downward, it will cause the abutting plate 62 to rotate outward relative to the support plate 61, thereby pushing the rotating plate 52 and the scraper 53 close to the inner wall of the kneader body 1, and making the side of the scraper 53 close to the inner wall of the kneader body 1, so that the scraper 53 is pushed to continue to move downward by the rotating plate 52, causing the scraper 53 to move while scraping the material on the inner wall of the kneader body 1. When the scraper 53 moves away from the inner wall of the kneader body 1 to the inside of the kneader body 1 in the next upward movement of the sliding sleeve box 4, the side of the scraper 53 will contact the material mass inside the kneader body 1, thereby pushing the material mass to move to the middle, reducing the circumferential movement of the material to the stirring paddles 2, and the contact between the scraper 53 and the material will adhere the material scraped from the inner wall of the kneader body 1 to the surface of the large material mass, so that the material adhering to the inner wall of the kneader body 1 is continuously kneaded by the stirring paddles 2.

[0043] When the material kneading is completed, the vacuum state inside the kneader body 1 is released and the discharge port is opened, and the inside of the kneader body 1 returns to the standard atmospheric pressure state, the sliding sleeve box 4 will move upward relative to the fixed block 3, restoring its initial inside pressure, causing the sliding sleeve box 4 to drive the scraping assembly 5 to move upward while the scraper 53 is driven by the rotating plate 52 to move in the direction of the abutting assembly 6, pushing the material inside the kneader body 1 to concentrate in the middle of the kneader body 1, facilitating the subsequent discharge of the material, and at the same time, by extending the screw rod from one side of the discharge port into the inside of the discharge pipe 8, driving the screw rod to rotate and cooperating with the rotation of the stirring paddles 2, the material is discharged through the discharge pipe 8.
