Description

Technical Field

[0001] The utility model relates to the technical field of adhesive preparation, in particular to an adhesive preparation system. Background Art

[0002] High-viscosity adhesives have a wide range of applications in the industrial field due to their excellent bonding performance, heat resistance, chemical corrosion resistance, and mechanical strength.

[0003] In the prior art, high-viscosity adhesives are prepared using a mixer. The mixer stirs and mixes raw materials to prepare the adhesive, and then discharges the material through a delivery pump arranged below the mixer. However, due to the long distance between the outer edge of the rotor inside the mixer and the rotor of the delivery pump, a dead zone for delivery is formed. During the actual working process, the adhesive often clogs in the dead zone for delivery, resulting in the inability to discharge the adhesive inside the mixer and affecting the production efficiency. Summary of the Utility Model

[0004] The applicant of the present utility model aims at the above-mentioned disadvantages in the existing production technology and provides an adhesive preparation system. By setting a stirring component and a delivery component, the dead material zones in the first cavity and the second cavity can be eliminated, thereby preventing the high-viscosity material from accumulating and solidifying at the discharge port of the first cavity. The materials in the first cavity and the second cavity can be emptied and drained completely without material residue, and it is suitable for preparing high-viscosity materials.

[0005] The technical solution adopted by the present utility model is as follows:

[0006] An adhesive preparation system includes a first cavity and a second cavity communicated with the first cavity. A stirring component is installed inside the first cavity, and the end of the stirring component extends out of the first cavity and is connected to the output end of a first driving component. A delivery component is installed inside the second cavity, and the end of the delivery component extends out of the second cavity and is connected to the output end of a second driving component. The discharge port of the second cavity is connected to the inlet of a filling machine through a discharge pipe group;

[0007] The first driving component drives the stirring component to rotate, thereby stirring and preparing the material inside the first cavity. The second driving component drives the delivery component to rotate, thereby driving the prepared material to flow into the filling machine through the discharge pipe group.

[0008] As a further improvement of the above technical solution:

[0009] The first cavity and the second cavity adopt an integral structure.

[0010] The outer edge of the stirring component is tangent to the outer edge of the delivery component.

[0011] The stirring assembly and the conveying assembly are arranged orthogonally.

[0012] A first valve is installed on the discharge pipe group.

[0013] A connecting branch pipe is installed on the discharge pipe group, and the end of the connecting branch pipe is connected to the return port opened on the first cavity.

[0014] A second valve is installed on the connecting branch pipe.

[0015] Both the first cavity and the second cavity are supported by mounting brackets.

[0016] The stirring assembly includes at least one stirring rotor.

[0017] The conveying assembly includes at least one screw.

[0018] The beneficial effects of the present utility model are as follows:

[0019] The structure of the present utility model is compact and reasonable, and it is convenient to operate. By arranging the stirring assembly and the conveying assembly in an orthogonal manner and making the outer edge of the stirring assembly tangent to the outer edge of the conveying assembly, the dead material areas in the first cavity and the second cavity are eliminated, which is suitable for preparing high-viscosity materials, and can empty and discharge the materials in the first cavity and the second cavity completely without material residue. At the same time, the conveying assembly can further perform strong shearing, mixing and kneading on the materials, so as to obtain a more delicate, uniform and shiny rubber compound. The rotors and conveying screws in the present utility model have various arrangement forms and diverse working modes, with high flexibility in use.

[0020] In the present utility model, a wall scraping structure without dead angles is adopted between the stirring assembly and the inner wall surface of the first cavity. When the stirring assembly rotates, it can fully stir and mix the materials inside the first cavity, and can force the materials to form a circulation inside the first cavity, so that they cannot stay on the inner wall surface of the first cavity.

[0021] Both the first cavity and the second cavity in the present utility model are closed spaces. Before the preparation system works, vacuum pumping operation will be carried out through the vacuum pumping port to remove the air and water vapor in the first cavity and the second cavity to prevent material contamination. When the preparation system works, nitrogen will be introduced into the first cavity and the second cavity through the gas injection port. At the same time, nitrogen will also be introduced at the shaft seal of the stirring assembly and the shaft seal at the tail of the conveying assembly for sealing to isolate the external air and avoid solidification of the materials inside the first cavity and the second cavity.

[0022] In the present utility model, by setting the connecting branch pipe, after the materials are extruded from the second cavity by the conveying assembly, they can flow back into the inside of the first cavity through the discharge pipe group and the connecting branch pipe in sequence, so that the stirring assembly can circulate and stir the materials to improve the fineness and gloss of the finished materials and improve the product quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will describe the detailed embodiments of the present utility model with reference to the accompanying drawings.

[0030] The structure and function of the present utility model are as follows:

[0031] As Figures 1 - 5 shown, an adhesive preparation system includes a first cavity 1 and a second cavity 2 communicating with the first cavity 1. A stirring assembly 5 is installed inside the first cavity 1, and the end of the stirring assembly 5 extends outside the first cavity 1 and is connected to the output end of the first drive assembly 3. A conveying assembly 6 is installed inside the second cavity 2, and the end of the conveying assembly 6 extends outside the second cavity 2 and is connected to the output end of the second drive assembly 4. The discharge port of the second cavity 2 is connected to the inlet of the filling machine 9 through a discharge pipe group 7. The first drive assembly 3 drives the stirring assembly 5 to rotate, so as to stir and prepare the materials inside the first cavity 1. The second drive assembly 4 drives the conveying assembly 6 to rotate, so as to drive the prepared materials to flow into the filling machine 9 through the discharge pipe group 7.

[0032] In the present utility model, the first cavity 1 and the second cavity 2 adopt an integrated structure, and a sealed space is formed inside. The second cavity 2 is orthogonally arranged at the bottom of the first cavity 1. The stirring assembly 5 and the conveying assembly 6 are orthogonally arranged, and the outer edge of the stirring assembly 5 is tangent to the outer edge of the conveying assembly 6. This arrangement can eliminate the dead material areas inside the first cavity 1 and the second cavity 2, thereby preventing high-viscosity materials from accumulating and solidifying at the discharge port of the first cavity 1 (i.e., the communication hole between the first cavity 1 and the second cavity 2), enabling the complete evacuation and drainage of the materials inside the first cavity and the second cavity, without material residue, and being applicable to the preparation of high-viscosity materials.

[0033] In addition, hot oil jackets are respectively provided outside the first cavity 1 and the second cavity 2, and the temperature control inside the first cavity 1 and the second cavity 2 is realized through an external hot oil system, further preventing material blockage.

[0034] The first driving assembly 3 includes at least one motor. Similarly, the second driving assembly 4 also includes at least one motor. The motors in the first driving assembly 3 are in one-to-one correspondence with the stirring rotors 501, and the motors in the second driving assembly 4 are in one-to-one correspondence with the screws 601.

[0035] One end of the discharge pipe group 7 is connected to the discharge port of the second cavity 2. At the same time, the other end is connected to the inlet of the filling machine 9. A first valve 11 is installed on the discharge pipe group 7. The discharge pipe group 7 is used for discharging and conveying, and conveys the materials extruded from the discharge port of the second cavity 2 to the filling machine 9. The first valve 11 is used to control the on-off of the discharge pipe group 7.

[0036] A connecting branch pipe 8 is installed on the discharge pipe group 7. The end of the connecting branch pipe 8 is connected to the return material port opened on the first cavity 1. A second valve 12 is installed on the connecting branch pipe 8. The connecting branch pipe 8 can be connected to the discharge pipe group 7 through a tee. A second valve 12 is installed on the connecting branch pipe 8, and the second valve 12 can control the on-off of the connecting branch pipe 8. By setting the connecting branch pipe 8, after the materials are extruded from the second cavity 2, they can flow back into the inside of the first cavity 1 successively through the discharge pipe group 7 and the connecting branch pipe 8, so that the preparation system can perform cyclic stirring on the materials, thereby improving the fineness and gloss of the finished materials and improving the product quality.

[0037] After the materials are completely processed, under the dual action of the stirring assembly 5 and the conveying assembly 6, the materials are completely discharged from the first cavity 1 and the second cavity 2 and are discharged into the filling machine 9 through the discharge pipe group 7, and the filling machine 9 fills the finished materials.

[0038] In addition, a dead - angle - free wall - scraping structure (with only a tiny gap left) is adopted between the stirring assembly 5 and the inner wall surface of the first cavity 1. When the stirring assembly 5 rotates, it can fully stir and mix the materials inside the first cavity 1, and can force the materials to form a circulation inside the first cavity 1, so that the materials cannot stay on the inner wall surface of the first cavity 1.

[0039] A liquid material feeding port, a powder material feeding port, a return material port, an air injection port, and a vacuum pumping port are respectively arranged on the wall surface of the first cavity 1. The first cavity 1 and the second cavity 2 are enclosed spaces. Before the preparation system works, a vacuum pumping operation is carried out through the vacuum pumping port, which can remove the water vapor in the first cavity 1 and the second cavity 2 to prevent material contamination. When the preparation system is working, nitrogen is introduced into the first cavity 1 and the second cavity 2 through the air injection port. At the same time, nitrogen is also introduced at the shaft seal of the stirring assembly 5 and the shaft seal at the tail of the conveying assembly 6 to seal and isolate the external air, avoiding the solidification of the materials inside the first cavity 1 and the second cavity 2.

[0040] Both the first cavity 1 and the second cavity 2 are supported by the mounting frame 10. The mounting frame 10 is assembled at the bottom of the second cavity 2 and is used to support the first cavity 1 and the second cavity 2. The second driving assembly 4 is supported by a mobile trolley, which is convenient for adjusting the layout position of the second driving assembly 4 and improving the flexibility of use of the preparation system.

[0041] The stirring assembly 5 is used to stir and mix the materials inside the first cavity 1. The stirring assembly 5 includes at least one stirring rotor 501. A single stirring rotor 501 can adopt a stirring paddle. When there are multiple stirring rotors 501 arranged inside the first cavity 1, as Figure 1 shown, two adjacent stirring rotors 501 can be arranged in a meshing and staggered manner, or, as Figure 2 shown, two adjacent stirring rotors 501 can be placed tangentially. In addition, multiple stirring rotors 501 can adopt a working mode of rotating in the same direction or a working mode of rotating in opposite directions.

[0042] The conveying assembly 6 includes at least one screw 601. The conveying assembly 6 has the functions of kneading, mixing and conveying the materials, and can improve the characteristics and appearance quality of the materials. When there are multiple screws 601 arranged inside the second cavity 2, two adjacent screws 601 can be placed tangentially or can be arranged in a meshing and staggered manner. In addition, multiple screws 601 can adopt a working mode of rotating in the same direction or a working mode of rotating in opposite directions. After the conveying assembly 6 starts to rotate, the materials enter the inside of the second cavity 2 from the discharge port of the first cavity 1, and after being continuously kneaded and ground by the conveying assembly 6, they are conveyed to the filling machine 9 through the discharge pipe group 7.

[0043] The working process of the present utility model is as follows:

[0044] Close the first valve 11, connect the vacuum pumping port to the output end of an external negative pressure source, evacuate the first cavity 1 and the second cavity 2 through the external negative pressure source, and then introduce nitrogen gas through the gas injection port into the first cavity 1 and the second cavity 2 to break the vacuum, so as to form an atmospheric pressure environment inside the first cavity 1 and the second cavity 2;

[0045] After the vacuum breaking is completed, stop introducing nitrogen gas into the first cavity 1 and the second cavity 2, close the second valve 12, start the first driving assembly 3 to drive the stirring assembly 5 to rotate, and then put liquid materials into the first cavity 1 through the liquid material feeding port and put powder materials into the first cavity 1 through the powder material feeding port. Under the stirring action of the stirring assembly 5, the powder materials and liquid materials in the first cavity 1 are continuously mixed and stirred;

[0046] When the reaction between the powder materials and liquid materials in the first cavity 1 stops, or when the powder materials and liquid materials in the first cavity 1 are evenly mixed, open the second valve 12, start the second driving assembly 4 to drive the conveying assembly 6 to rotate. Under the combined action of the stirring assembly 5 and the conveying assembly 6, the mixed materials in the first cavity 1 enter the second cavity 2, and are further mixed, kneaded and conveyed through the conveying assembly 6. Then, the mixed materials in the second cavity 2 enter the first cavity 1 again through the discharge pipe group 7, the connecting branch pipe 8 and the return material port in sequence, so as to perform cyclic stirring treatment on the mixed materials to prepare an adhesive;

[0047] After the adhesive is prepared, close the second valve 12, open the first valve 11. Under the combined action of the stirring assembly 5 and the conveying assembly 6, the adhesive enters the filling machine 9 through the conveying pipe group 7, and finally the filling machine 9 fills the adhesive.

[0048] The above description is an explanation of the present utility model, not a limitation thereof. The scope defined by the present utility model is referred to the claims. Any form of modification can be made within the protection scope of the present utility model.
