Description

Technical Field

[0001] The utility model relates to the technical field of vacuum kneading machines, in particular to a vacuum kneading machine whose inner wall is not easy to adhere to high-viscosity materials. Background Art

[0002] Kneader is a special mixing equipment, which usually uses two paddles arranged side by side with different speeds to generate shear force. Different paddle speeds can quickly shear the mixed materials, so that the materials can be mixed evenly.

[0003] As shown in the reference case "A kneading device with vacuum heat protection and automatic feeding and discharging" announcement number "CN219540189U", when processing viscous materials, the kneading machine automatically loads the materials into the kneading chamber through the automatic feeding and discharging device. Then, the operation control starts the motor to make the stirring paddle rotate in the chamber for kneading. At the same time, the electric telescopic rod drives the scraper to move up and down on the chamber wall to scrape off the adhering materials to ensure uniform kneading;

[0004] However, silicone rubber can be quickly and evenly sheared and mixed. However, during the mixing process, the material tends to adhere to the blades and the stirring rod, especially when the blades are engaged with each other for mixing. This adhesion phenomenon is particularly obvious, which brings additional burden to the subsequent cleaning work.

[0005] Therefore, a vacuum kneading machine is proposed, the inner wall of which is not easy to adhere to high-viscosity materials, so as to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a vacuum kneading machine with an inner wall that is not easy to adhere to high-viscosity materials in order to solve the above-mentioned problem, thereby improving the problem that during the stirring process, the materials tend to adhere to the blades and the stirring rod, especially when the blades are engaged with each other for stirring, this adhesion phenomenon is particularly obvious, which brings an additional burden to the subsequent cleaning work.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a vacuum kneading machine with high-viscosity materials that are not easy to adhere to the inner wall, comprising: a fixed seat, a motor and a control seat are fixedly installed on the surface of one side of the fixed seat, a kneading box is arranged on one side of the motor, and an anti-sticking kneading mechanism is arranged inside the kneading box for reducing the adhesion of materials when kneading the materials, wherein the anti-sticking kneading mechanism also includes a kneading bin fixedly installed inside the kneading box, both sides of the bottom of the kneading bin are arranged in an arc shape, a kneading component is arranged inside the kneading bin, and a sealing component is arranged on one side of the kneading box. When in use, the kneading component can be used to mix the materials evenly while reducing the adhesion of the materials inside the equipment, reducing the waste of materials and simplifying the cleaning process. Through effective mixing and reduced adhesion, the material processing performance is improved, making the quality of the final product more stable. The sealing component provides better sealing performance, prevents material leakage, and ensures the maintenance of vacuum during the kneading process.

[0008] Preferably, the kneading assembly includes two stirring rods arranged inside the kneading bin, one side of the stirring rods is fixedly connected to the output end of the motor, one side of the two stirring rods is connected by a belt drive, an auger blade is fixedly installed on the outer side of the stirring rod, and a dividing blade is fixedly installed on the outer side of the auger blade, and the volume of the dividing blade away from the stirring rod gradually decreases. When in use, the two stirring rods can be driven to rotate by the motor, and the coordinated work of the two stirring rods and the use of the auger blades can create a complex flow pattern in the kneading bin. This flow pattern is conducive to uniform mixing and shearing of materials, thereby improving mixing efficiency. The auger blades and the dividing blades optimize the contact area and shearing force of the materials, which helps to reduce the adhesion problem of high-viscosity materials during the kneading process. The design of the gradually decreasing volume of the dividing blade before contacting the material can effectively separate the material adhering to the stirring rod and the blade, thereby reducing the difficulty of cleaning.

[0009] Preferably, the kneading assembly also includes a plurality of protrusions fixedly mounted on the surface of the stirring rod, and the plurality of protrusions are equidistantly distributed on the surface of the stirring rod. The protrusions reduce the contact area between the material and the stirring rod by increasing the roughness of the surface of the stirring rod, which helps to reduce the adhesion of the material. For materials with high viscosity, such as silicone rubber, the cleaning process can be simplified and downtime can be reduced.

[0010] Preferably, a driving plate is fixedly mounted on the outer side of the auger blade, and a rubber scraper is fixedly mounted on the other side of the driving plate, the rubber scraper is in contact with the inner wall of the kneading bin, and the side of the rubber scraper close to the kneading bin is arranged in an inclined shape. When the auger blade rotates, the rubber scraper can rotate closely against the inner wall of the kneading bin, effectively scraping off the material adhered to the inner wall, reducing the waste of material and the cleaning workload after kneading.

[0011] Preferably, the sealing assembly includes a sealing cover rotatably mounted on one side of the kneading box, a plurality of connecting plates are fixedly mounted on both sides of the sealing cover, a plurality of support plates are fixedly mounted on the outer side of the kneading box, the plurality of support plates are aligned with the plurality of connecting plates, and a same limiting rod is installed through adjacent connecting plates and support plates. Before kneading, the sealing cover and the kneading box can be closed, and the kneading box can be sealed by the sealing cover, so that the kneading box is more stable during kneading.

[0012] Preferably, the connecting plate is arranged in a U shape, and the supporting plate is located below the connecting plate. When the connecting plate contacts the supporting plate, the supporting plate is located inside the connecting plate. The U-shaped connecting plate can increase the contact surface between the connecting plate and the supporting plate, making the connection between the two more stable.

[0013] Preferably, a sealing ring is fixedly installed inside the sealing cover, and the sealing cover is extended from one side of the sealing ring. When the sealing cover contacts the kneading box, one side of the sealing ring enters the inner wall of the kneading box and the kneading bin, thereby further improving the sealing effect when the sealing cover is closed.

[0014] The beneficial effects of the utility model are:

[0015] 1. During use, the kneading component can not only mix the materials evenly, but also reduce the adhesion of materials inside the equipment, reduce material waste, and simplify the cleaning process. Through effective mixing and reduced adhesion, the material handling performance is improved, making the quality of the final product more stable. The sealing component provides better sealing performance, prevents material leakage, and ensures the vacuum maintenance during the kneading process;

[0016] 2. The convex particles increase the roughness of the stirring rod surface and reduce the contact area between the material and the stirring rod, which helps to reduce the adhesion of the material. For materials with high viscosity, such as silicone rubber, it can simplify the cleaning process and reduce downtime. When the auger blade rotates, the rubber scraper can rotate close to the inner wall of the kneading bin and effectively scrape off the material adhering to the inner wall, reducing material waste and cleaning workload after kneading.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a vacuum kneading machine with high-viscosity materials not easily adhering to the inner wall comprises: a fixed base 1, a motor 101 and a control base 102 are fixedly mounted on one side surface of the fixed base 1, a kneading box 103 is arranged on one side of the motor 101, and an anti-adhesion kneading mechanism 2 is arranged inside the kneading box 103 for reducing the adhesion of materials when kneading the materials, wherein the anti-adhesion kneading mechanism 2 also includes a kneading bin 21 fixedly mounted inside the kneading box 103, both sides of the bottom of the kneading bin 21 are arranged in an arc shape, a kneading component 22 is arranged inside the kneading bin 21, and a sealing component 23 is arranged on one side of the kneading box 103. When in use, the kneading component 22 can be used to mix the materials evenly while reducing the adhesion of the materials inside the equipment, reducing the waste of materials and simplifying the cleaning process. Through effective mixing and reduced adhesion, the material processing performance is improved, so that the quality of the final product is more stable. The sealing component 23 provides better sealing performance, prevents material leakage, and ensures the vacuum maintenance during the kneading process.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, the kneading component 22 includes two stirring rods 221 arranged inside the kneading bin 21, one side of the stirring rod 221 is fixedly connected to the output end of the motor 101, one side of the two stirring rods 221 is connected through a belt drive, an auger blade 222 is fixedly installed on the outer side of the stirring rod 221, and a dividing blade 223 is fixedly installed on the outer side of the auger blade 222, and the volume of the dividing blade 223 away from the stirring rod 221 gradually decreases, and the dividing blade 223 can rotate synchronously when the stirring rod 221 and the auger blade 222 rotate, and can contact the material in front of the auger blade 222. When in use, the two stirring rods 221 can be driven to rotate by the motor 101, and the coordinated work of the two stirring rods 221 and the auger blade 222 can create a complex flow pattern in the kneading bin 21. This flow pattern is conducive to uniform mixing and shearing of the material, thereby improving the mixing efficiency. The auger blade 222 and the dividing blade 223 optimize the contact area and shearing force of the material, which helps to reduce the adhesion problem of high-viscosity materials during the kneading process, and the dividing blade 223 can be used to mix and cut the material. The design of the blade 223 gradually decreasing in volume before contacting the material can effectively separate the material adhering to the stirring rod 221 and the blade, reducing the difficulty of cleaning. The kneading component 22 also includes a plurality of convex particles 224 fixedly mounted on the surface of the stirring rod 221. The plurality of convex particles 224 are equidistantly distributed on the surface of the stirring rod 221. The convex particles 224 increase the roughness of the surface of the stirring rod 221, thereby reducing the contact area between the material and the stirring rod 221, which helps to reduce the adhesion of the material. For materials with high viscosity, such as Silicone rubber can simplify the cleaning process and reduce downtime. A driving plate 225 is fixedly installed on the outer side of the auger blade 222, and a rubber scraper 226 is fixedly installed on the other side of the driving plate 225. The rubber scraper 226 is in contact with the inner wall of the kneading bin 21. The side of the rubber scraper 226 close to the kneading bin 21 is set to be inclined. When the auger blade 222 rotates, the rubber scraper 226 can rotate close to the inner wall of the kneading bin 21, effectively scraping off the material adhering to the inner wall, reducing the waste of material and the cleaning workload after kneading.

[0026] like Figure 2 and Figure 5As shown, the sealing assembly 23 includes a sealing cover 231 rotatably mounted on one side of the kneading box 103, a plurality of connecting plates 232 are fixedly mounted on both sides of the sealing cover 231, a plurality of supporting plates 227 are fixedly mounted on the outer side of the kneading box 103, the plurality of supporting plates 227 are aligned with the plurality of connecting plates 232, and a same limiting rod 228 is installed through adjacent connecting plates 232 and supporting plates 227. Before kneading, the sealing cover 231 and the kneading box 103 can be closed, and the kneading box 103 can be sealed by the sealing cover 231, so that the kneading box 103 is more stable during kneading. The connecting plates 232 are set as U The support plate 227 is located below the connecting plate 232. When the connecting plate 232 contacts the support plate 227, the support plate 227 is located inside the connecting plate 232. The U-shaped connecting plate 232 can increase the contact surface between the connecting plate 232 and the support plate 227, making the connection between the two more stable. A sealing ring 233 is fixedly installed inside the sealing cover 231, and one side of the sealing ring 233 extends out of the sealing cover 231. When the sealing cover 231 contacts the kneading box 103, one side of the sealing ring 233 enters the inner wall of the kneading box 103 and the kneading bin 21, thereby further improving the sealing effect of the sealing cover 231 when it is closed.

[0027] When the utility model is in use, the two stirring rods 221 can be driven to rotate by the motor 101. The two stirring rods 221 work together with the auger blades 222 to create a complex flow pattern in the kneading bin 21. This flow pattern helps to evenly mix and shear the materials, thereby improving the mixing efficiency. The auger blades 222 and the dividing blades 223 optimize the contact area and shearing force of the materials, which helps to reduce the adhesion problem of high-viscosity materials during the kneading process. The design of the dividing blades 223 gradually decreasing in volume before contacting the materials can effectively separate the materials adhering to the stirring rods 221 and the blades, thereby reducing the cleaning work. The convex particles 224 reduce the contact area between the material and the stirring rod 221 by increasing the roughness of the surface of the stirring rod 221, which helps to reduce the adhesion of the material. For materials with high viscosity, such as silicone rubber, the cleaning process can be simplified and the downtime can be reduced. When the auger blade 222 rotates, the rubber scraper 226 can rotate close to the inner wall of the kneading bin 21, effectively scraping off the material adhering to the inner wall, reducing the waste of material and the cleaning workload after kneading. Before kneading, the sealing cover 231 and the kneading box 103 can be closed, and the kneading box 103 can be sealed by the sealing cover 231, so that the kneading box 103 is more stable during kneading.
