Description

Technical Field

[0001] This utility model relates to the field of flame retardant adhesive processing technology, specifically to a pressing device for flame retardant adhesives. Background Technology

[0002] Currently, in the colloid production industry, it is usually necessary to classify and package colloids produced in large quantities, and then fill the colloids into small packages. This process often requires the use of a pressing machine.

[0003] In the pressing equipment for flame retardant adhesives, flame retardants (such as aluminum hydroxide, magnesium hydroxide, etc.) are prone to agglomeration or precipitation, and cannot be evenly dispersed in the adhesive. This results in unstable flame retardant performance, poor flame retardant effect in local areas, and uneven physical properties of the adhesive (such as strength and flexibility), affecting the reliability of the final product. Existing equipment does not include a stirring structure, and the unstirred adhesive and flame retardant are not fully mixed, which may lead to stratification or air bubbles during pressing. Therefore, we propose a pressing equipment for flame retardant adhesives to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pressing device for flame-retardant adhesives to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing device for flame-retardant adhesive, comprising a mixing tank, a first motor fixedly installed at the upper middle position of the mixing tank, feed inlets fixedly connected to both the left and right sides of the upper end of the mixing tank, a stirring rod fixedly connected to the lower end of the first motor, and a stirring frame fixedly connected to the lower end of the stirring rod, a stirring column fixedly connected to the upper outer side of the stirring frame, and a connecting frame fixedly connected to the upper end of the stirring column, a discharge valve fixedly installed at the lower middle position of the mixing tank, a fixing plate provided at the lower end of the mixing tank, and a conveyor roller connected to the fixing plate, a conveyor belt wrapped around the outside of the conveyor roller, a second motor fixedly installed at the front end of the conveyor roller, a storage frame fixedly connected to the upper end of the conveyor belt, a fixing frame provided on the right side of the mixing tank, and a cylinder fixedly installed at the upper end of the fixing frame, and a pressure plate fixedly connected to the lower end of the cylinder.

[0006] Preferably, there are two sets of feed inlets, and the two sets of feed inlets are configured with a structure that is wider at the top and narrower at the bottom.

[0007] Preferably, the lower end of the stirring rack has a uniform baffle with protruding rods, and there are four sets of stirring racks in total. The sides of the four sets of stirring racks that are close to each other are all fixedly connected to the stirring rod.

[0008] Preferably, the stirring column is configured as a spiral structure, the connecting frame is movably engaged with the inner wall of the mixing tank, and the lower interior of the mixing tank is configured as a V-shaped structure.

[0009] Preferably, the outer surface of the conveyor roller is evenly distributed with teeth, and the inner surface of the conveyor belt meshes with the conveyor roller through the teeth.

[0010] Preferably, there are five sets of storage frames, and the upper end of each storage frame has an opening, with the upper end of the opening corresponding to the position of the discharge valve.

[0011] Preferably, the outer dimension of the pressure plate is equal to the inner dimension of the storage frame.

[0012] This utility model provides a pressing device for flame-retardant adhesives, which has the following beneficial effects:

[0013] The first motor drives the stirring rod and stirring frame, which, together with the rotation of the stirring column, can fully mix the flame retardant with the adhesive, preventing the flame retardant from agglomerating or settling, ensuring that the flame retardant is evenly dispersed in the adhesive, and improving the flame retardant performance and consistency of the product. The conveyor belt below the mixing box is driven by the second motor, which can automatically transport the mixed adhesive to the storage box or the next process, realizing continuous production, reducing manual intervention, and improving production efficiency.

[0014] The cylinder-driven pressure plate on the fixed frame can compact the mixed rubber material. Through pressure control, it ensures uniform density of the rubber material, avoids air bubbles or delamination, and improves the physical properties of the product. The first motor and the second motor control the mixing and conveying respectively, and the cylinder controls the pressing. The operation is simple, reduces manual operation, reduces labor intensity, and improves production safety. Attached image description:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a pressing device for flame-retardant adhesive, including a mixing tank 1, a first motor 2 fixedly installed at the middle of the upper end of the mixing tank 1, feed inlets 3 fixedly connected to both the left and right sides of the upper end of the mixing tank 1, a stirring rod 4 fixedly connected to the lower end of the first motor 2, and a stirring frame 5 fixedly connected to the lower end of the stirring rod 4, a stirring column 6 fixedly connected to the upper outer side of the stirring frame 5, and a connecting frame 7 fixedly connected to the upper end of the stirring column 6, a discharge valve 8 fixedly installed at the middle of the lower end of the mixing tank 1, a fixing plate 9 provided at the lower end of the mixing tank 1, and a conveyor roller 10 connected to the fixing plate 9, a conveyor belt 11 wrapped around the outside of the conveyor roller 10, a second motor 12 fixedly installed at the front end of the conveyor roller 10, a storage frame 13 fixedly connected to the upper end of the conveyor belt 11, a fixing frame 14 provided on the right side of the mixing tank 1, and a cylinder 15 fixedly installed at the upper end of the fixing frame 14, and a pressure plate 16 fixedly connected to the lower end of the cylinder 15.

[0024] There are two sets of feed inlets 3, both with a wider top and narrower bottom design. The lower end of the mixing rack 5 has evenly spaced baffles with protruding rods. There are four sets of mixing racks 5 in total, with the sides of each set fixedly connected to the mixing rod 4. The mixing column 6 has a spiral structure. The connecting frame 7 is movably engaged with the inner wall of the mixing tank 1. The lower part of the mixing tank 1 has a V-shaped structure. The wider top and narrower bottom design facilitates quick pouring of the adhesive and flame retardant, reducing the risk of spillage. The narrower bottom design prevents large pieces of material or impurities from getting stuck in the feed inlets 3, ensuring smooth entry of materials into the mixing tank 1. Different materials (such as adhesive and flame retardant) can be added to the two sets of feed inlets 3 separately, achieving layered feeding and facilitating subsequent mixing. The protruding rod at the lower end of the mixing rack 5 generates a strong shearing effect on the adhesive material when rotating, which helps to break up the agglomeration of flame retardant and promote uniform dispersion. The four sets of mixing racks 5 are close to each other and fixed on the mixing rod 4 to form a multi-layered mixing effect, ensuring that the material is fully mixed in a short time. The protruding rod design can effectively handle high-viscosity adhesive materials and avoid mixing dead corners. The spiral structure of the mixing column 6 generates axial thrust when rotating, causing the material to tumble upward from the bottom of the mixing box 1 to form a circulating flow and prevent material sedimentation. The spiral mixing column 6 works in conjunction with the mixing rack 5 to form a three-dimensional mixing effect, ensuring that all parts of the material are fully mixed. The spiral structure can flexibly adjust the mixing intensity and is suitable for adhesive materials and flame retardants of different viscosities.

[0025] The outer surface of the conveyor roller 10 is evenly distributed with teeth. The inner surface of the conveyor belt 11 meshes with the conveyor roller 10 through the teeth. Five sets of storage frames 13 are provided. An opening is provided at the top of each storage frame 13, and the top of the opening corresponds to the position of the discharge valve 8. The outer dimension of the pressure plate 16 is equal to the inner dimension of the storage frame 13. The teeth on the outer surface of the conveyor roller 10 mesh with the inner surface of the conveyor belt 11, ensuring that the conveyor belt 11 will not slip during transport and guaranteeing the stability of material transport. The tooth structure provides stronger traction, especially suitable for transporting high-viscosity or heavy materials. The meshing of the teeth with the conveyor belt 11 makes the material transport position more precise, facilitating the connection with subsequent processes (such as storage or forming). Five sets of storage frames 1... 3. It can simultaneously receive materials from different batches, realizing multi-station storage or processing, improving production efficiency. The opening at the top of the storage frame 13 corresponds to the position of the discharge valve 8, and the material can be accurately allocated to the designated storage frame 13 as needed to adapt to different production requirements. The multi-storage frame 13 design avoids the congestion problem of a single storage frame 13, ensuring continuous production. The outer dimensions of the pressure plate 16 are consistent with the inner dimensions of the storage frame 13, which can uniformly compact the material and avoid excessive or insufficient local pressure. The cooperation between the pressure plate 16 and the storage frame 13 ensures that the material has uniform density in the storage frame 13, improving product quality. The size of the pressure plate 16 matches the storage frame, which can effectively prevent the material from overflowing during the compaction process and keep the production environment clean.

[0026] Working principle: The adhesive and flame retardant are added through the two sets of feed ports 3 at the top of the mixing tank 1. The first motor 2 drives the stirring rod 4 to rotate, which in turn drives the stirring frame 5 and the stirring column 6 to stir. The protruding rod at the bottom of the stirring frame 5 generates shear force on the material, breaking up the agglomeration of the flame retardant and promoting uniform dispersion. The spiral structure of the stirring column 6 pushes the material up and down to form a circulating flow, ensuring that the material is fully mixed. The discharge valve 8 at the bottom of the mixing tank 1 is opened, and the mixed adhesive is discharged through the discharge valve 8. The opening at the top of the storage frame 13 corresponds to the position of the discharge valve 8, ensuring that the material falls accurately into the designated storage frame 13. The second motor 12 drives the conveyor roller 10 to rotate. Through the meshing action of the teeth and the conveyor belt 11, the storage frame 13 is smoothly transported to the bottom of the pressure plate 16. The cylinder 15 drives the pressure plate 16 to move downward, compacting the adhesive in the storage frame 13.
