DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See attached Figure 1-10A curing agent material stirring device includes an outer cylinder 1, whose internal space is used to accommodate water and an inner cylinder 2. The inner cylinder 2 is arranged inside the outer cylinder 1, and a water bath heating space is formed between the two. A heating tube 3 is arranged inside the outer cylinder 1 to heat the water in the water bath space, thereby achieving uniform heating of the inner cylinder 2 and the material inside it.

[0035] A stirring shaft 4 is provided inside the inner cylinder 2, and the stirring shaft 4 is located at the center of the inner cylinder 2. A plurality of stirring arms 5 are installed on the outer wall thereof for stirring the material in the inner cylinder 2. An axial cavity 41 with a bottom passing through is provided in the stirring shaft 4, and an arm cavity 51 is provided in the stirring arm 5. An elastic hose 6 is connected between the stirring arm 5 and the stirring shaft 4 so that the axial cavity 41 is connected to the arm cavity 51, and the axial cavity 41 is connected to the outer cylinder 1 so that water between the outer cylinder 1 and the inner cylinder 2 can flow freely into the axial cavity 41 and the arm cavity 51.

[0036] When in use, add a proper amount of water between the outer cylinder 1 and the inner cylinder 2. At this time, the water will enter the shaft cavity 41 and the arm cavity 51, and then the water therein will be heated to a suitable temperature by the heating tube 3. The hot water is evenly distributed in the water bath space, ensuring that the periphery and the interior of the material can be evenly heat transferred, so that the internal and external temperatures of the material are consistent during the stirring process, avoiding the mixing effect being affected by the temperature difference. In addition, the heat generated during the stirring process can be taken away through the conduction of the stirring arm 5 and the stirring shaft 4, preventing the excessively high mixing temperature from having an adverse effect on the chemical properties of the material.

[0037] An accommodating cavity 42 for accommodating the stirring arm 5 is formed on the outer wall of the stirring shaft 4, and rotating shafts 52 are provided on both sides of the bottom of the stirring arm 5, and the stirring arm 5 is rotatably connected in the accommodating cavity 42 through the rotating shaft 52. A liftable scraper ring 7 is provided inside the inner cylinder 2, and the outer wall of the scraper ring 7 fits the inner wall of the inner cylinder 2, and the inner wall of the scraper ring 7 fits the outer wall of the stirring shaft 4. When the interior of the inner cylinder 2 is cleaned after the materials are mixed, the stirring arm 5 is controlled to rotate and flipped into the accommodating cavity 42, and then the scraper ring 7 is controlled to move downward. At this time, the scraper ring 7 scrapes the inner wall of the inner cylinder 2, the outer wall of the stirring shaft 4 and the bottom wall of the stirring arm 5. The adhered materials are scraped off to facilitate the cleaning of the inner cylinder 2, reduce the possibility of material residue, and significantly improve the cleanliness of the equipment.

[0038] In order to improve the stirring effect of the stirring arm 5, the upper part of the stirring arm 5 is a trapezoidal structure that is close to the middle, and the lower surface is an arc surface that matches the outer wall of the stirring shaft 4. When the stirring arm 5 is flipped out of the accommodating cavity 42, the side away from the stirring shaft 4 is tilted downward.

[0039] In order to achieve the flipping of the stirring arm 5, a pull rope 431 is provided inside the shaft cavity 41. The bottom of the pull rope 431 penetrates the outer wall of the stirring shaft 4 and is connected to the upper side of the stirring arm 5. The top of the pull rope 431 penetrates to the top of the outer cylinder 1 and is connected to the outer wall of the winding drum 432. A first motor 433 is provided on one side of the winding drum 432, which is used to drive the winding drum 432 to reel in the pull rope 431. A support frame 434 is provided at the bottom of the winding drum 432, which is used to support the winding drum 432 and the first motor 433. When the first motor 433 is started, the winding drum 432 reels in the pull rope 431. At this time, one end of the pull rope 431 pulls the stirring arm 5 to flip into the accommodating cavity 42 until the stirring arm 5 completely enters the accommodating cavity 42.

[0040] A guide member 435 is provided in the shaft cavity 41 , and a plurality of guide rollers are provided in the guide member 435 for guiding the pull rope 431 , which is beneficial to the stable operation of the device.

[0041] A second motor 81 is provided at the top of the outer cylinder 1, and the output end of the second motor 81 is connected to a driving gear 82. The outer wall of the driving gear 82 is meshedly connected with a driven gear 83. The top of the stirring shaft 4 passes through the outer cylinder 1, and it passes through the outer wall of the outer cylinder 1 and is fixedly connected to the inner wall of the driven gear 83. When the second motor 81 is started, the driving gear 82 drives the driven gear 83 to rotate, and further the stirring shaft 4 drives the stirring arm 5 to rotate, and stirring work can be performed at this time.

[0042] The support frame 434 is installed at one end of the stirring shaft 4 passing through the outer cylinder 1, so that the pull rope 431, the winding disk 432, the first motor 433 and the support frame 434 rotate synchronously with the stirring shaft 4, which is conducive to the stable operation of the device.

[0043] A water outlet 441 is provided on the outer wall on the upper side of the stirring shaft 4 so that the shaft cavity 41 is connected to the inner cavity of the inner cylinder 2. The vertical inner wall of the outer cylinder 1 and the vertical inner wall of the inner cylinder 2 are arranged in parallel so that an equidistant gap is formed therebetween. A liftable liquid pressure ring 9 is provided inside the outer cylinder 1. The outer wall of the liquid pressure ring 9 fits with the vertical inner wall of the outer cylinder 1, and the inner wall of the liquid pressure ring 9 fits with the vertical inner wall of the inner cylinder 2, so that when the liquid pressure ring 9 moves downward, the water in the outer cylinder 1 enters the inner cylinder 2. When the liquid pressure ring 9 moves downward, the water in the outer cylinder 1 moves to the upper part of the shaft cavity 41, and further enters the inner cylinder 2 through the water outlet 441, so that the interior of the inner cylinder 2 can be cleaned by heating waste water, thereby reducing the loss of water resources.

[0044] A sealing plug 442 is slidably connected to the inside of the shaft cavity 41. A supporting spring 443 is provided inside the shaft cavity 41. The bottom of the supporting spring 443 is connected to the top of the sealing plug 442, so that the sealing plug 442 is blocked at the position of the water outlet 441, so that the water outlet 441 is closed in the initial state, preventing the water vapor of the heated water from entering the inner cylinder 2 through the water outlet 441 and affecting the humidity of the material during the mixing process.

[0045] A third motor 101 is provided at the top of the outer cylinder 1, and a driving pulley 102 is connected to the output end of the third motor 101. The outer wall of the driving pulley 102 is connected to a belt 103 for transmission. The belt 103 is internally connected to a first driven pulley 104 and a second driven pulley 105 arranged in pairs for transmission. The bottom of the first driven pulley 104 is connected to a first screw rod 106, and the bottom of the second driven pulley 105 is connected to a second screw rod 107. The two first screw rods 106 penetrate into the interior of the inner cylinder 2 and are connected to the internal threads of the scraper ring 7. The two second screw rods 107 penetrate into the interior of the inner cylinder 2 and are connected to the internal threads of the scraper ring 7. It passes through the interior of the outer cylinder 1 and is connected with the internal thread of the liquid pressure ring 9, so that when the third motor 101 is started, the scraper ring 7 and the liquid pressure ring 9 can synchronously move up and down. When the third motor 101 is started, the driving pulley 102 drives the first driven pulley 104 and the second driven pulley 105 to rotate through the belt 103, and further makes the first screw rod 106 and the second screw rod 107 rotate synchronously. At this time, the scraper ring 7 and the liquid pressure ring 9 can move downward synchronously, and the scraping operation of the inner wall of the inner cylinder 2 is completed during the process of injecting water into the inner cylinder 2, which greatly improves the cleaning efficiency.

[0046] The outer wall of the rotating shaft 52 is sleeved with a torsion spring 53, and the two ends of the torsion spring 53 are respectively connected to the stirring arm 5 and the accommodating chamber 42, so that the stirring arm 5 is separated from the accommodating chamber 42 in the initial state. The torsion spring 53 allows the stirring arm 5 to remain separated from the accommodating chamber 42 in the initial state, thereby enabling more effective material mixing during the stirring process.

[0047] In order to facilitate the addition of materials, a feed hopper 11 is provided on the top of the outer cylinder 1, and the bottom of the feed hopper 11 is connected with the inner cylinder 2. A water inlet pipe 12 with a valve is provided on the upper side of the outer wall of the outer cylinder 1, and the water inlet pipe 12 is connected with the inner cavity of the outer cylinder 1 to facilitate the addition of water into the outer cylinder 1. The bottom of the inner cylinder 2 is inclined, and an inner drain pipe 13 with a valve is provided at the bottom of the lowest side. The inner drain pipe 13 runs through the outer cylinder 1 for discharging water in the inner cylinder 2. An outer drain pipe 14 with a valve is provided on the lower side of the outer wall of the outer cylinder 1 for discharging water in the outer cylinder 1, so that the entire stirring device is more flexible and convenient during use.

[0048] Working principle: add a proper amount of water into the outer cylinder 1 through the water inlet pipe 12, then the water will enter the shaft cavity 41 and the arm cavity 51, and the water inside will be heated to a suitable temperature through the heating tube 3, and then add materials into the inner cylinder 2 through the feed hopper 11, start the second motor 81, and then the driving gear 82 drives the driven gear 83 to rotate, and further the stirring shaft 4 drives the stirring arm 5 to rotate in the inner cylinder 2, so that the materials are mixed evenly.

[0049] After the mixing is completed, the first motor 433 is started, and the winding disk 432 reels the pull rope 431, so that the stirring arm 5 is turned over into the accommodating chamber 42, and then the third motor 101 is started. At this time, the driving pulley 102 drives the first driven pulley 104 and the second driven pulley 105 to rotate through the belt 103, and further rotates the first screw rod 106 and the second screw rod 107. At this time, the liquid pressure ring 9 and the scraper ring 7 move downward synchronously, and the liquid pressure ring 9 moves downward to press the water in the outer cylinder 1 into the inner cylinder 2. The scraper ring 7 moves downward to scrape off the materials adhered to the inner wall of the inner cylinder 2 and the outer wall of the stirring shaft 4. When the liquid pressure ring 9 and the scraper ring 7 move downward to the bottom of the inner cavity of the inner cylinder 2, the first motor 433 is controlled to rotate in the opposite direction, so that the winding disk 432 releases the winding of the pull rope 431. At this time, under the action of the torsion spring 53, the stirring arm 5 flips out of the accommodating chamber 42, and then the second motor 81 is controlled to start. At this time, the stirring shaft 4 drives the stirring arm 5 to rotate, so that the water in the inner cylinder 2 rotates to complete the cleaning of the inner cylinder 2.
