Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, and in particular to an apparatus for producing MS adhesive. Background Technology

[0002] MS adhesive (silane-modified polyether adhesive) is an environmentally friendly elastic sealant based on silane-terminated polyether polymer. 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, it forms a three-dimensional network structure through a hydrolysis-condensation reaction triggered by moisture. Therefore, MS adhesive needs to be produced under sealed conditions in each process to ensure that it is mixed and produced in an anhydrous and oxygen-free atmosphere.

[0003] However, existing production equipment for ordinary adhesives cannot fully meet the sealing requirements of MS adhesives. Moreover, during the mixing process of MS adhesives, various additives need to be added frequently. In the process of adding various additives, it is easy for a large amount of water vapor and oxygen to be mixed into the mixing tank, which is not conducive to the feeding and mixing of MS adhesives to achieve the sealing conditions during the production process. Therefore, existing production equipment cannot guarantee the performance of MS adhesives. Summary of the Invention

[0004] The purpose of this invention is to provide a production apparatus for MS adhesive, which aims to solve the production requirements of an oxygen-free and water-free environment during the production process of MS adhesive.

[0005] To address this, the present invention provides the following technical solution: a production device for MS adhesive, comprising a frame, multiple feeding mechanisms, and a mixing vessel. The frame has a platform with multiple connecting rods on it. Each connecting rod has a support beam at its end. Multiple feeding mechanisms are located below the support beams and supported on the platform. Each feeding mechanism includes a material bucket and a pressure plug. The pressure plug is movably and sealingly fitted into the material bucket. A pressure cylinder is mounted on the support beam. The telescopic rod end of the pressure cylinder is connected to a lifting plate through the support beam. The lifting plate is connected to the pressure plug. A first material pipe is located at the bottom of the material bucket. The first material pipe is connected to a metering pump. The outlet end of the metering pump is connected to a second material pipe, which is connected to the mixing vessel. The mixing vessel includes a vessel body and a cover. The cover has an inlet corresponding to the second material pipe. The pressure cylinder and the pressure plug push the material in the material bucket, and the material is quantitatively extruded and transported into the mixing vessel under the action of the metering pump.

[0006] Furthermore, the number of the feeding mechanisms is two.

[0007] Furthermore, the pressure plug is equipped with a spring cap. During the placement of the material container, a small amount of volatile substances will be generated. When the material container needs to be depressurized, the volatile gas inside the material container can be released by pressing the spring cap.

[0008] Furthermore, a sealing ring is provided at the outer edge of the side wall of the pressure plug, and the sealing connection between the pressure plug and the material barrel is achieved through the sealing fit between the sealing ring and the inner wall of the material barrel.

[0009] Furthermore, the pressure plug has a first conical portion at its bottom, and the material hopper has a second conical portion at its bottom corresponding to the first conical portion. By providing the second conical portion, the material hopper can better facilitate material discharge, while by providing the pressure plug with the first conical portion, the pressure plug can better and more thoroughly compress the material in the hopper during the pressing process.

[0010] Furthermore, the cover body has an additive feeding end, which contains a feeding chamber. The bottom of the feeding chamber has an inlet. The end of the additive feeding end has an additive feeding device, which includes a flange and a fixed plate. The flange is connected to the end face of the additive feeding end. Multiple support pillars are provided between the flange and the fixed plate. The fixed plate has a sealing cylinder. The telescopic rod end of the sealing cylinder has a piston extending into the feeding chamber. The piston can extend and retract to seal and press the inlet. The additive feeding end has a side tube on its side wall, and a receiving part on the side tube. The receiving part has an opening at its upper part. Multiple silicone patches are attached to the surface of the opening, and the multiple silicone patches circumferentially surround the opening and form a seal. Using the additive feeding device, various additives for producing MS adhesive can be added effectively into the reactor, while ensuring the sealing of the mixing reactor during the addition of various additives.

[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] 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.

[0014] This invention uses a pressurizing cylinder to pressurize the feeding mechanism, and then uses a metering pump to quantitatively add various materials required for mixing MS glue through a pipeline. During the addition process, the materials are added to the mixing vessel in an air-free and moisture-free environment, ensuring that the MS glue is mixed in a dry and air-free environment in the mixing vessel.

[0015] This invention, by setting an additive feeding device on the cover, ensures that the additives are added under sealed conditions during the mixing process of various additives into the mixing vessel, thereby ensuring a dry and airless mixing environment for the MS adhesive in the mixing vessel.

Detailed Implementation

[0024] The embodiments of this utility model will be briefly described below with reference to the accompanying drawings.

[0025] An MS adhesive production apparatus, referenced Figures 1-2 The system includes a frame 1, multiple feeding mechanisms 2, and a mixing vessel 6. The frame 1 has a platform 11 with multiple connecting rods 12. Each connecting rod 12 has a support beam 13 at its end. The feeding mechanisms 2 are located below the support beams 13 and supported on the platform 11. Typically, there are two feeding mechanisms 2, one primarily for storing resin base materials and the other for storing plasticizers. Each feeding mechanism 2 includes a material tank 21 and a pressure plug 22. The pressure plug 22 is movably and sealingly fitted into the material tank 21. A pressure cylinder 3 is mounted on the support beam 13, and the telescopic rod end of the pressure cylinder 3 is connected through the support beam 13. A lifting plate 4 is connected to a pressure plug 22. The bottom of the material barrel 21 is provided with a first material pipe 7, which is connected to a metering pump 5. The outlet end of the metering pump 5 is connected to a second material pipe 8, which is connected to a mixing vessel 6. When the mixing vessel 6 needs to be fed, the pressure cylinder 3 pushes the pressure plug 22, which pushes the material in the material barrel 21. The material is then quantitatively squeezed and transported into the mixing vessel 6 by the metering pump 5. Various materials are mixed in the mixing vessel 6 to obtain MS glue. Therefore, this production device can ensure the sealing performance of the feeding process.

[0026] Reference Figure 3 , Figure 4The pressure plug 22 of the feeding mechanism 2 is equipped with a spring cap 221. During the placement of the material barrel 21, a small amount of volatile substances will be generated. When the material barrel 21 needs to be depressurized, the volatile gas in the material barrel 21 can be released by pressing the spring cap 221. A sealing ring 222 is provided at the outer edge of the side wall of the pressure plug 22. The sealing ring 222 and the inner wall of the material barrel 21 are sealed together to achieve a sealed connection between the pressure plug 22 and the material barrel 21. The bottom of the pressure plug 22 is provided with a first conical part 223. The bottom of the material barrel 21 is provided with a second conical part 211 corresponding to the first conical part 223. By providing the second conical part 211, the material barrel 21 can better realize the discharge of materials. By providing the first conical part 223 for the pressure plug 22, the pressure plug 22 can better and more thoroughly press out the materials in the material barrel 21 during the pressing process.

[0027] Reference Figure 5 The mixing vessel 6 includes a vessel body 61 and a cover 62. A discharge port 611 is located on the lower side wall of the vessel body 61 to facilitate the discharge of MS adhesive. A stirring motor 63 is located at the center of the top of the cover 62, used to stir and mix the materials inside the vessel body 61. A pair of inlets 621 for pumping materials are located on one side of the cover 62. The inlets 621 are connected to a second feed pipe 8, allowing materials to be pumped into the vessel body 61 from the feeding mechanism 2 while it is sealed. A pair of vent pipes 622 are located on the cover 62. One vent pipe 622 is connected to a protective gas, such as nitrogen, allowing the protective gas to be easily introduced into the vessel body 61. This protective gas displaces and expels air from the vessel body 61, ensuring that the MS adhesive is mixed in an oxygen-free and moisture-free environment. The other vent pipe 622 can be used as a venting gas to maintain pressure inside the mixing vessel 6.

[0028] Reference Figure 6 , Figure 7An additive feeding end 623 is provided on the cover 62. The additive feeding end 623 has a feeding chamber 624 inside, and an inlet 625 is provided at the bottom of the feeding chamber 624. An additive feeding device 64 is provided at the end of the additive feeding end 623. The additive feeding device 64 includes a flange 641 and a fixed plate 643. The flange 641 is connected to the end face of the additive feeding end 623. Multiple support pillars 642 are provided between the flange 641 and the fixed plate 643. A sealing cylinder 644 is provided on the fixed plate 643. The telescopic rod end of the sealing cylinder 644 has a piston rod 649 extending into the feeding chamber 624. The piston rod 649 can extend and retract to seal and press the inlet 625. The additive feeding... A side tube 647 is provided on the side wall of end 623, and a receiving part 646 is provided on the side tube 647. An opening 646a is provided on the upper part of the receiving part 646. Multiple silicone patches 648 are attached to the surface of the opening 646a. The multiple silicone patches 648 surround the opening 646a and form a seal on the opening 646a. The height of the opening of the side tube 647 on the side wall of the additive feeding end 623 is lower than the height of the piston column 649 of the sealing cylinder 644 after contraction. Therefore, when the additive is fed after the piston column 649 contracts, the additive can enter the feeding chamber 624 through the receiving part 646 and the side tube 647, and finally enter the mixing vessel 6 through the inlet 625 from the feeding chamber 624.

[0029] In this embodiment, during additive feeding, the sealing cylinder 644 is first opened, causing the piston column 649 to disengage from the inlet 625. The feeder can then break through the center of multiple silicone pads 648 downwards and enter the receiving section 646. The silicone pads 648 remain in contact with the feeder during the compression process, ensuring a good seal with the outside during additive feeding. After feeding is complete and the feeder leaves, the silicone pads 648 spring back due to elasticity and re-adhere together, ensuring the additive feeding device... With a sealing effect of 64, the various additives to be added are received by the receiving part 646 and flow into the feeding chamber 624 of the additive feeding end 623 through the side pipe 647. Finally, the various additives directly enter the vessel body 61 of the mixing vessel 6 through the inlet 625. After the additives enter the vessel body 61, the sealing cylinder 644 is activated, so that the piston column 649 presses against the inlet 625 to form a complete seal. Therefore, this production device can well ensure the sealing performance of the mixing vessel 6 during the addition of various additives.

[0030] In this embodiment, the flange 641 is provided with a linear bearing 645 at its center, corresponding to the telescopic rod of the sealing cylinder 644. The telescopic rod of the sealing cylinder 644 is sleeved in the linear bearing 645. The linear bearing 645 is a sealed sliding bearing. Through the linear bearing 645, a sliding and sealed connection is formed between the telescopic rod of the sealing cylinder 644 and the flange 641. The piston column 649 moves up and down more smoothly and accurately, ensuring that the piston column 649 can better press and seal the feed port 625.

[0031] 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.
