Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, and in particular to a mixing tank for MS adhesive production. Background Technology

[0002] MS adhesive (silane-modified polyether adhesive) is an environmentally friendly elastic sealant based on silane-terminated polyether polymers. It is widely used in construction, automobile manufacturing, rail transportation and other fields. It features low VOC, high elasticity and excellent weather resistance. During use, moisture triggers a hydrolysis-condensation reaction to form a three-dimensional network structure. Therefore, MS adhesive requires a sealed mixing vessel during mixing. In existing mixing vessels, the opening and closing of the mixing vessel during the addition of various additives allows air to enter. Small amounts of air or moisture entering the mixing vessel cause the produced MS adhesive to easily clump, affecting the performance of the MS adhesive. Summary of the Invention

[0003] The purpose of this invention is to provide a mixing vessel for MS glue production, which aims to solve the problem that in the process of adding various additives in existing mixing vessels, a small amount of air or moisture can easily enter the mixing vessel, causing the produced MS glue to easily clump together, thus affecting the use effect of MS glue.

[0004] To address this, the present invention provides the following technical solution: a mixing vessel for MS adhesive production, comprising a vessel body and a lid, with a sealing ring between the vessel body and the lid. A stirring motor is located at the center of the top of the lid, and a stirring paddle is connected to the drive shaft of the stirring motor, extending into the vessel body. An additive feeding end is provided on the lid, with a feeding chamber inside the feeding end. An inlet is located at the bottom of the feeding chamber. An additive feeding device is provided at the end of the additive feeding end, comprising a flange and a fixing plate. The flange is connected to the end face of the additive feeding end. Multiple support columns are provided between the flange and the fixed plate. A sealing cylinder is provided on the fixed plate. The telescopic rod end of the sealing cylinder is provided with a piston column extending into the feeding chamber. The piston column can extend and retract to seal and press the inlet. The additive feeding end has a side tube on its side wall. The side tube has a receiving part. The receiving part has an opening at its upper part. Multiple silicone patches are attached to the surface of the opening. The multiple silicone patches surround the opening and form a seal on the opening. When adding additives, the sealing cylinder is first opened, causing the piston to disengage from the inlet. The feeder can then break through the silicone pads from the center and enter the receiving section. During the compression process, the silicone pads remain in contact with the feeder, ensuring a good seal with the outside during additive addition. After addition is complete and the feeder leaves, the silicone pads rebound due to elasticity and re-adhere, ensuring the sealing effect of the additive addition device. The various additives to be added, received by the receiving section, flow into the feeding chamber of the additive addition end through the side pipe. Finally, the various additives enter the mixing vessel directly through the inlet. After the additives enter the vessel, the sealing cylinder is activated, causing the piston to press against the inlet to form a complete seal.

[0005] Furthermore, a pair of inlets for pumping in resin base material are provided on one side of the cover. The inlets can be connected to external feed pipes, enabling the pumping of resin base material into the reactor body while it is sealed.

[0006] Furthermore, the cover is provided with a pair of vent pipes, one of which is connected to a protective gas, such as nitrogen, so that the protective gas can be easily introduced into the reactor. The protective gas can be used to replace and expel the air in the reactor, ensuring that the MS glue is in an oxygen-free and water-free environment during the mixing process in the reactor. The other vent pipe can be used as a venting gas to ensure the pressure in the mixing reactor.

[0007] Furthermore, the cover body has a sealing part located below the stirring motor, and the sealing part has a sealing chamber inside. The bottom of the sealing chamber has a shaft hole. The stirring shaft of the stirring paddle is connected to the drive shaft of the stirring motor through the sealing chamber. The stirring paddle has a protrusion at the end of its stirring shaft corresponding to the sealing chamber. The protrusion causes the stirring paddle to be locked below the sealing part. A sealing sleeve is provided between the stirring shaft of the stirring paddle and the shaft hole. The sealing sleeve fits onto the outside of the stirring shaft and is locked inside the sealing chamber.

[0008] Furthermore, multiple sealing rings are provided between the protruding post and the sealed chamber.

[0009] Furthermore, the silicone patch is positioned at an angle downwards towards the center of the opening.

[0010] Furthermore, the feed inlet has a first sealing protrusion on its upper surface, and the piston rod has a second sealing protrusion on its inner wall corresponding to the first sealing protrusion. When the piston rod presses against the feed inlet, a sealing fit is formed between the first sealing protrusion and the second sealing protrusion. Through the sealing fit between the first sealing protrusion and the second sealing protrusion, the sealing of the inside of the mixing vessel is well guaranteed after the piston rod presses against and presses against the feed inlet.

[0011] Furthermore, the height of the side opening of the side tube at the additive feeding end is lower than the height of the piston column of the sealing cylinder after it has contracted. Thus, when the additive is fed after the piston column has contracted, the additive can enter the feeding chamber through the receiving part along the side tube, and finally enter the mixing vessel through the inlet from the feeding chamber.

[0012] Furthermore, the flange is equipped with a linear bearing at its center corresponding to the telescopic rod of the sealing cylinder, and the telescopic rod of the sealing cylinder is sleeved within the linear bearing. Through the linear bearing, a sliding connection is formed between the telescopic rod of the sealing cylinder and the flange, allowing the piston rod to move up and down more smoothly and accurately, ensuring that the piston rod can better press and seal the inlet.

[0013] This invention utilizes a silicone patch on the receiving section of the additive feeding device to achieve initial sealing of the additive feeding device during the feeding process. This prevents air and moisture from entering the mixing vessel during the feeding process, greatly reducing the possibility of air or moisture entering the mixing vessel during the additive feeding process.

[0014] This invention, by setting a sealing cylinder, uses a piston rod to seal and pressurize the feed inlet, ensuring that the additive feeding device further seals the mixing vessel after the additive is added, thus guaranteeing the sealing effect of the mixing vessel during the mixing process. It abandons traditional valves or other sealing methods such as screw caps, and the use of a sealing cylinder makes operation simple, convenient and quick. Attached Figure Description

Detailed Implementation

[0023] The embodiments of this utility model will be briefly described below with reference to the accompanying drawings.

[0024] A mixing vessel for MS glue production, reference Figures 1-2The apparatus includes a vessel body 1 and a lid 2. A sealing ring 6 is provided between the vessel body 1 and the lid 2 to seal the connection between them. A discharge port 11 is located on the lower side wall of the vessel body 1 to facilitate the discharge of MS adhesive. A stirring motor 3 is located at the center of the top of the lid 2. A stirring paddle 5 is connected to the drive shaft of the stirring motor 3 and extends into the vessel body 1. To achieve a sealing effect between the stirring shaft of the stirring paddle 5 and the lid 2 during the connection process, refer to... Figure 3 The cover 2 has a sealing part 24 located below the stirring motor 3. The sealing part 24 has a sealing chamber 25 inside. The bottom of the sealing chamber 25 has a shaft hole 26. The stirring shaft of the stirring paddle 5 is connected to the drive shaft of the stirring motor 3 through the sealing chamber 25. The end of the stirring shaft of the stirring paddle 5 has a protrusion 51 corresponding to the sealing chamber 25. The protrusion 51 makes the stirring paddle 5 stuck below the sealing part 24. A sealing sleeve 7 is provided between the stirring shaft of the stirring paddle 5 and the shaft hole 26. The sealing sleeve 7 fits on the outside of the stirring shaft and is stuck in the sealing chamber 25. Multiple sealing rings 8 are also provided between the protrusion 51 and the sealing chamber 25. Through the sealing sleeve 7 and the sealing rings 8, the sealing effect between the stirring shaft and the cover 2 is ensured. Therefore, the mixing vessel can well ensure the sealing effect during the connection process of the power transmission device and improve the performance of MS glue after mixing.

[0025] A pair of inlets 21 for pumping resin base material are provided on one side of the cover body 2. The inlets 21 can be connected to external feed pipes to achieve the pumping of resin base material into the reactor body 1 under sealed conditions. A pair of vent pipes 23 are provided on the cover body 2. One of the vent pipes 23 is connected to a protective gas, such as nitrogen, so that the protective gas can be easily introduced into the reactor body 1. The protective gas can replace and expel the air in the reactor body 1, ensuring that the MS glue is in an oxygen-free and water-free environment during the mixing process in the reactor body 1. The other vent pipe 23 can be used as an air release gas to ensure the pressure in the mixing reactor.

[0026] Reference Figure 4 , Figure 5 An additive feeding end 22 is provided on the cover body 2. The additive feeding end 22 has a feeding chamber 221 inside, and an inlet 222 is located at the bottom of the feeding chamber 221. An additive feeding device 4 is provided at the end of the additive feeding end 22. The additive feeding device 4 includes a flange 41 and a fixed plate 43. The flange 41 is connected to the end face of the additive feeding end 22. Multiple support pillars 42 are provided between the flange 41 and the fixed plate 43. A sealing cylinder 44 is provided on the fixed plate 43. A piston rod 49 extending into the feeding chamber 221 is provided at the telescopic rod end of the sealing cylinder 44. The piston rod 49 can extend and retract to seal and press the inlet 222. (Refer to...) Figure 6The upper surface of the feed inlet 222 is provided with a first sealing protrusion 223, and the inner wall of the piston column 49 is provided with a second sealing protrusion 491 corresponding to the first sealing protrusion 223. When the piston column 49 presses against the feed inlet 222, a sealing fit is formed between the first sealing protrusion 223 and the second sealing protrusion 491. Through the sealing fit between the first sealing protrusion 223 and the second sealing protrusion 491, the piston column 49 can effectively ensure the sealing of the inside of the mixing vessel after pressing against the feed inlet 222. Therefore, this mixing vessel can effectively ensure the sealing performance of the mixing vessel during the addition of various additives.

[0027] The additive feeding end 22 has a side tube 47 on its side wall, a receiving part 46 on the side tube 47, an opening 461 on the upper part of the receiving part 46, and a plurality of silicone patches 48 attached to the surface of the opening 461. The plurality of silicone patches 48 surround the opening 461 and form a seal on the opening 461. The height of the opening of the side tube 47 on the side wall of the additive feeding end 22 is lower than the height of the piston column 49 of the sealing cylinder 44 after contraction. Therefore, when the additive is fed after the piston column 49 contracts, the additive can enter the feeding chamber 221 through the receiving part 46 and the side tube 47, and finally enter the mixing vessel through the inlet 222 from the feeding chamber 221.

[0028] Reference Figure 7 The silicone pad 48 is inclined downward in the center direction of the opening 461. When the additive is added, the sealing cylinder 44 is opened first, so that the piston column 49 is disengaged from the feed port 222. The feeder can break the silicone pad 48 downward from the center of the multiple silicone pads 48 and enter the receiving part 46. The silicone pad 48 can still be attached to the feeder during the compression process, which ensures that the additive can be well sealed with the outside when it is added. After the addition is completed and the feeder is removed, the silicone pad 48 rebounds due to the elasticity and reattaches together, which ensures the sealing effect of the additive feeding device 4. The various additives that need to be added received by the receiving part 46 flow into the feeding chamber 221 of the additive feeding end 22 through the side pipe 47. Finally, the various additives directly enter the body 1 of the mixing vessel through the feed port 222. After the additives enter the body 1, the sealing cylinder 44 is activated, so that the piston column 49 presses against the feed port 222 to form a complete seal.

[0029] In this embodiment, the flange 41 is provided with a linear bearing 45 corresponding to the telescopic rod of the sealing cylinder 44 at its center. The telescopic rod of the sealing cylinder 44 is sleeved in the linear bearing 45. The linear bearing 45 is a sealed sliding bearing. Through the linear bearing 45, a sliding and sealed connection is formed between the telescopic rod of the sealing cylinder 44 and the flange 41, making the piston column 49 move up and down more smoothly and accurately, ensuring that the piston column 49 can better press and seal the feed port 222.

[0030] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
