Description

Technical Field

[0001] The present invention relates to the technical field of silicone resin processing, in particular to vacuum drying and decolorizing equipment for silicone resin processing. Background Art

[0002] Silicone resin is a silicon-based synthetic resin. In order to improve its strength, durability and other functions, staff usually dry and decolorize the silicone resin. During the drying and decolorization process, staff often use a vacuum environment to reduce the boiling point while heating the silicone resin to solidify it. At the same time, the dried silicone resin is crushed into particles. Then the staff use ultraviolet rays and other strong light to decolorize the silicone resin with light waves to achieve the purpose of effective drying and fading.

[0003] Due to the limited speed and range of light wave fading, a small part of the pigment in the silicone resin is not easy to decolorize. The current drying and decolorization device is not convenient for intermittent addition of decolorizing agents such as hydrogen peroxide when drying and decolorizing the silicone resin, which leads to insufficient decolorization of the silicone resin, resulting in poor decolorization effect. In addition, the interior of the silicone resin is not easy to absorb heat after curing, and it is extremely difficult to crush the silicone resin in time with a single crushing method. At the same time, the existing drying and decolorization device is not convenient for timely cutting the dried silicone resin blocks, which leads to uneven and insufficient drying, resulting in low drying efficiency. Summary of the Invention

[0004] In order to overcome the above shortcomings, the present invention provides a vacuum drying and decolorization equipment for silicone resin processing, which can intermittently add a decolorizer to make the silicone resin decolorized more fully and can promptly cut the dried block silicone resin to make the drying more uniform and sufficient, thereby improving the drying and decolorization efficiency of the silicone resin.

[0009] As an improvement of the above-mentioned scheme, the feeding mechanism includes a support frame, which is fixedly connected to the bottom of the outer frame, and a liquid cylinder is fixedly connected to the support frame. The top of the liquid cylinder passes through the bottom of the outer frame, and the liquid cylinder is located below the stirring plate. A discharge hole is opened at the top of the liquid cylinder, and the discharge hole of the liquid cylinder is located inside the outer frame. A feed hole is opened on one side of the liquid cylinder, and the feed hole of the liquid cylinder is located outside the outer frame. A one-way valve 1 is fixedly connected to the feed hole of the liquid cylinder, and a one-way valve 2 is fixedly connected to the discharge hole of the liquid cylinder. A fixing rod is fixedly connected to the bottom of the stirring plate, and the fixing rod portion is located inside the liquid cylinder. A piston is fixedly connected to the bottom of the fixing rod, and the side of the piston contacts the inner wall of the liquid cylinder.

[0010] As an improvement to the above scheme, it also includes a cutting mechanism, which is arranged on the motor, and is used to cut the silicone resin scooped up by the stirring plate. The cutting mechanism includes a bevel gear 1, which is fixedly connected to the output shaft of the motor, and a prismatic sleeve is sleeved on the output shaft of the motor, and the bottom of the prismatic sleeve contacts the prismatic shaft, and the prismatic sleeve is fixedly connected to the bevel gear 2. One side of the inner wall of the outer frame is fixedly connected to a limiting frame, and the limiting frame is rotatably connected to a rotating shaft, and the rotating shaft is perpendicular to the output shaft of the motor, and the side of the rotating shaft close to the prismatic shaft is fixedly connected to a transmission bevel gear, and both sides of the transmission bevel gear are respectively meshed with the bevel gear 1 and the bevel gear 2, and the prismatic sleeve is slidably connected to a sliding frame, and the bottom of the sliding frame contacts the stirring plate, and the outer side of the bottom of the sliding frame is evenly fixedly connected with a blade.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention heats and dries the silicone resin through the heating ring, the ultraviolet lamp ring fades the pigment light waves in the silicone resin, the vacuum pump extracts the air in the outer frame and the evaporated water in the silicone resin, so that a vacuum environment is formed in the outer frame to lower the boiling point, thereby accelerating the drying rate of the silicone resin, and the motor drives the stirring plate to stir the silicone resin, thereby making the silicone resin dry more evenly, and the stirring plate rotates while driving the sliding rod to rotate, and the sliding rod rotates along the annular groove of the isolation ring to make the crushing plate move up and down reciprocatingly to continuously crush the silicone resin, thereby making the silicone resin more delicate, and the stirring plate moves up and down reciprocatingly to make the piston intermittently push the decolorant into the outer frame through the one-way valve 1 and the one-way valve 2, thereby making the decolorant continuously mixed with the silicone resin, and the mixing of the decolorant and the silicone resin will quickly precipitate the pigment that cannot be faded in the silicone resin, thereby making the decolorization of the silicone resin faster and more effective, thereby improving the decolorization efficiency of the silicone resin.

[0014] 2. While stirring the silicone resin, the motor drives bevel gear 1 to rotate. The rotation of bevel gear 1 drives bevel gear 2 through the transmission bevel gear. The prismatic sleeve, sliding frame and blade rotate in the opposite direction together. The stirring plate moves up and down, causing the blade to move up and down, so that the blade is always a certain distance above the stirring plate. While the stirring plate rotates, it will scoop up some silicone resin blocks that have not been crushed after drying. The reverse rotation of the blade will cut the silicone resin scooped up by the stirring plate, so that the silicone resin is broken more comprehensively and fully, thereby enhancing the drying effect.

[0015] 3. The stirring plate will continuously scrape off the silicone resin attached to the lower part of the inner wall of the isolation ring while rotating and moving up and down. The sliding frame will drive the support rod and the wiping block to rotate together while the sliding frame moves upward. The wiping block will wipe off the silicone resin attached to the upper part of the inner wall of the isolation ring while rotating and moving up and down, thereby maintaining good thermal conductivity of the isolation ring and improving drying efficiency.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0031] The stirring mechanism includes an air pump 71, which is connected to one side of the outer frame 2 by bolts. The air pump 71 has an air extraction pipe connected to the interior of the outer frame 2. The air pump 71 is used to extract the air inside the outer frame 2 and the moisture evaporated from the silicone resin. The top of the inner wall of the outer frame 2 is connected to an ultraviolet lamp ring 72 by bolts. The ultraviolet lamp ring 72 is used to perform light wave fading on the silicone resin. The top of the outer frame 2 is connected to a motor 73 by bolts. The output shaft of the motor 73 is rotatably connected to the outer frame 2. The output shaft of the motor 73 passes through the ultraviolet lamp ring 72. The bottom of the output shaft of the motor 73 is connected to a prismatic shaft 74 by bolts. A stirring plate 75 is slidably connected to the prismatic shaft 74. The outer side of the stirring plate 75 is in contact with the inner wall of the isolation ring 6. The stirring plate 75 is used to stir the silicone resin while scraping off the silicone resin attached to the lower part of the inner wall of the isolation ring 6.

[0032] The blades of the stirring plate 75 are arranged obliquely, and the obliquely arranged blades of the stirring plate 75 are used to scoop up the dried block silicone resin.

[0033] The crushing mechanism includes a sliding rod 81, which is connected to one side of the stirring plate 75 by bolts. The sliding rod 81 is perpendicular to the prismatic shaft 74, and the end of the sliding rod 81 away from the prismatic shaft 74 is slidingly connected to the annular groove of the isolation ring 6. The bottom of each blade of the stirring plate 75 is connected to a crushing plate 82 by bolts. The three crushing plates 82 are in contact with the bottom of the inner wall of the outer frame 2. The crushing plates 82 are used to crush the dried silicone resin.

[0034] The feeding mechanism includes a support frame 91, which is welded to the bottom of the outer frame 2. A liquid cylinder 92 is connected to the support frame 91 by bolts. The top of the liquid cylinder 92 passes through the bottom of the outer frame 2. The liquid cylinder 92 is located below the stirring plate 75. A discharge hole is opened on the top of the liquid cylinder 92. The discharge hole of the liquid cylinder 92 is located inside the outer frame 2. A feed hole is opened on one side of the liquid cylinder 92. The feed hole of the liquid cylinder 92 is located outside the outer frame 2. A one-way valve 93 is fixedly connected to the feed hole of the liquid cylinder 92, and a one-way valve 94 is fixedly connected to the discharge hole of the liquid cylinder 92. A fixing rod 95 is welded to the bottom of the stirring plate 75, and the fixing rod 95 is partially located inside the liquid cylinder 92. A piston 96 is fixedly connected to the bottom of the fixing rod 95, and the side of the piston 96 is in contact with the inner wall of the liquid cylinder 92. The piston 96 is used to intermittently push the decolorizer into the outer frame 2 through the one-way valve 93 and the one-way valve 94.

[0035] First, the staff connects the decolorant to the feed hole of the liquid cylinder 92 through a pipe, and connects the collection pipe to the discharge port of the outer frame 2. Then the staff opens the solenoid valve 3 and pours the silicone resin into the outer frame 2 through the feed port of the outer frame 2. Then the staff closes the solenoid valve 3 and energizes the heating ring 5 and the ultraviolet lamp ring 72. Then the staff starts the vacuum pump 71 and the motor 73. When the heating ring 5 is energized, it will conduct heat through the isolation ring 6 to heat the silicone resin. When the ultraviolet lamp ring 72 is energized, the pigment in the silicone resin will be discolored by light waves. At the same time, the vacuum pump 71 will extract the air in the outer frame 2 and the evaporated water in the silicone resin, so that a vacuum environment is formed in the outer frame 2. In the vacuum environment, the boiling point of the water is reduced. In order to speed up the drying rate of the silicone resin, the output shaft of the motor 73 rotates, driving the prismatic shaft 74 and the stirring plate 75 to rotate together. The rotation of the stirring plate 75 will stir the silicone resin, thereby making the silicone resin dry more evenly and less likely to adhere to the inner wall of the isolation ring 6. The rotation of the stirring plate 75 will drive the sliding rod 81 to rotate, and the annular groove of the isolation ring 6 will first squeeze the sliding rod 81 to move upward, and then the sliding rod 81 continues to rotate, and the annular groove of the isolation ring 6 will squeeze the sliding rod 81 to move downward, and repeat this. While the sliding rod 81 rotates, it will move back and forth along the annular groove of the isolation ring 6. The up and down reciprocating movement of the sliding rod 81 will drive the stirring plate 75 and the crushing plate 82 to move back and forth together. The upward movement of the crushing plate 82 will make the dried silicone resin The piston 96 moves upwards to push the decolorant sucked into the outer frame 2 through the one-way valve 94 and the discharge hole of the liquid cylinder 92. Then, the piston 96 moves downwards to make the liquid cylinder 92 generate negative pressure under the action of the one-way valve 94, thereby causing the liquid cylinder 92 to absorb the connected decolorant through the one-way valve 93. Then, the piston 96 moves upwards again to push the decolorant sucked into the liquid cylinder 92 through the one-way valve 94 into the outer frame 2. Repeat this process. The piston 96 moves upwards to push the decolorant sucked into the outer frame 2 through the one-way valve 94. 93 and the one-way valve 2 94 will intermittently push the decolorant connected to the liquid cylinder 92 into the outer frame 2, so that the decolorant is continuously mixed with the silicone resin. The mixing of the decolorant and the silicone resin will quickly precipitate the pigment that cannot be faded in the silicone resin, thereby making the decolorization of the silicone resin faster and more effective, thereby improving the decolorization efficiency of the silicone resin. After the drying and decolorization is completed, the staff will first turn off the vacuum pump 71, and at the same time cut off the power to the heating ring 5 and the ultraviolet lamp ring 72. Then the staff will open the solenoid valve 2 4, and the rotating stirring plate 75 will gradually push the dried and decolorized silicone resin out through the discharge port of the outer frame 2, and then collect the silicone resin through the collection pipe. Then the staff will turn off the motor 73 and remove the connecting pipe of the decolorant from the feed hole of the liquid cylinder 92.Then remove the collecting tube from the discharge port of the outer frame 2.

[0036] Example 2: Based on Example 1, Figure 2-Figure 12 As shown, it also includes a cutting mechanism, which is arranged on the motor 73 and is used to cut the silicone resin scooped up by the stirring plate 75. The cutting mechanism includes a bevel gear 101, which is connected to the output shaft of the motor 73 through a flat key. A prismatic sleeve 102 is sleeved on the output shaft of the motor 73, and the bottom of the prismatic sleeve 102 contacts the prismatic shaft 74. A bevel gear 2 103 is connected to the prismatic sleeve 102 through a flat key. One side of the inner wall of the outer frame 2 is connected to a limiting frame 104 by bolts. The limiting frame 10 4 is rotatably connected to a rotating shaft 105, the rotating shaft 105 is perpendicular to the output shaft of the motor 73, the rotating shaft 105 is connected to a transmission bevel gear 106 on one side close to the prismatic shaft 74 through a flat key, the two sides of the transmission bevel gear 106 are respectively engaged with the bevel gear 1 101 and the bevel gear 2 103, the prismatic sleeve 102 is slidably connected to a sliding frame 107, the bottom of the sliding frame 107 is in contact with the stirring plate 75, and the outer side of the bottom of the sliding frame 107 is evenly connected with a blade 108 by bolts, and the blade 108 is used to cut block silicone resin.

[0037] When the blade 108 rotates in the opposite direction, the silicone resin 108 is cut and the silicone resin 108 is shoveled away by the stirring plate 75.

[0038] Example 3: Based on Example 2, Figure 2-Figure 12 As shown, it also includes a support rod 11, three of the support rods 11 are evenly welded on the top of the sliding frame 107, and the ends of the three support rods 11 away from each other are fixedly connected to a wiping block 12, and the three wiping blocks 12 are in contact with the inner wall of the isolation ring 6, and the wiping block 12 is used to wipe the silicone resin attached to the upper part of the inner wall of the isolation ring 6.

[0039] The wiping block 12 is made of sponge material, and the wiping block 12 made of sponge material is not likely to damage the isolation ring 6 during wiping.

[0040] The stirring plate 75 will continuously scrape off the silicone resin attached to the lower part of the inner wall of the isolation ring 6 while rotating and moving up and down. The sliding frame 107 will drive the support rod 11 and the wiping block 12 to rotate together while rotating. When the sliding frame 107 moves upward, it will drive the rotating wiping block 12 to move upward. The wiping block 12 will wipe off the silicone resin attached to the upper part of the inner wall of the isolation ring 6 while rotating and moving up and down, thereby maintaining good thermal conductivity of the isolation ring 6, thereby improving the drying efficiency.
