Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to an extrusion device for oil-resistant adhesives. Background Technology

[0002] Oil-resistant adhesives are specially designed to maintain their performance stability in environments containing grease, lubricating oil, or other oily media. These adhesives are widely used in the automotive, machinery manufacturing, and aerospace industries because they maintain good bond strength and physical properties even when in contact with oily substances. Oil-resistant adhesives typically use special polymer base materials with excellent resistance to oil erosion, maintaining their physical and chemical properties even after prolonged contact with oily substances. They not only have excellent bonding capabilities to various materials such as metals, plastics, and ceramics, but also maintain high-strength bonding in oily environments, ensuring a secure connection between components. They are suitable for applications in extreme environments. In addition to oil resistance, some oil-resistant adhesives also possess good resistance to acids, alkalis, and solvents, enabling long-term use in complex chemical environments. They can be applied through various methods such as dispensing, spraying, and brushing, making them easy to use and suitable for automated production lines.

[0003] Oil-resistant adhesives play an important role in many industries due to their unique resistance to oil erosion and excellent bonding performance. They are an indispensable key material. However, during the production process, air bubbles are generated in the adhesive, which can lead to a decrease in the bonding strength and durability of the finished adhesive.

[0004] Therefore, an extrusion device for oil-resistant adhesives is provided to effectively remove air bubbles from the adhesive, improve the density and appearance quality of the adhesive, and enhance the bonding strength and durability. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1-5 This invention provides an extrusion device for an oil-resistant adhesive. The device includes an extrusion table 1, a feeding platform 11 at the center of the top surface of the extrusion table 1, and an extrusion chamber 15 at the center of the interior of the extrusion table 1, extending through both sides of the extrusion table 1. A guide layer 14 is provided inside the top surface of the extrusion table 1, with one end of the guide layer 14 connected to the bottom of the feeding platform 11 and the other end connected to the extrusion chamber 15. Extrusion plates 4 are provided on both sides of the extrusion chamber 15, and a partition plate 41 is provided at the center of the top surface of the extrusion chamber 15. The shapes of the extrusion plates 4 and the partition plate 41 are the same as the cross-sectional shape of the extrusion chamber 15.

[0028] Specifically, a feeding platform 11 is provided at the center of the top surface of the extrusion table 1, and an extrusion chamber 15 is provided at the center of the interior of the extrusion table 1. The extrusion chamber 15 extends through both sides of the extrusion table 1, forming a cavity inside the extrusion table 1. The feeding platform 11 injects colloid into the extrusion chamber 15 to facilitate further processing of the colloid. A guide layer 14 is provided inside the top surface of the extrusion table 1. One end of the guide layer 14 is connected to the bottom of the feeding platform 11, and the other end of the guide layer 14 is connected to the extrusion chamber 15, facilitating the entry of colloid from the extrusion table 1 into the interior of the extrusion chamber 15. Extrusion plates 4 are provided on both sides of the extrusion chamber 15, and a partition plate 41 is provided at the center of the top surface of the extrusion chamber 15. The shapes of the extrusion plates 4 and the partition plate 41 are the same as the cross-sectional shape of the extrusion chamber 15. The extrusion plates 4 seal both ends of the extrusion chamber 15, and simultaneously extrude the colloid inside the extrusion chamber 15 by the extrusion plates 4. The partition plate 41 separates the colloid inside the extrusion chamber 15.

[0029] Multiple pairs of support columns 12 are provided on the bottom surface of the extrusion table 1. The support columns 12 are symmetrically distributed along the bottom surface of the extrusion table 1. A support beam 13 is provided at the bottom end of the support column 12. The other end of the support beam 13 is horizontally connected to the support column 12 on the other side. A reciprocating motor 3 is provided at the center of the top surface of the support beam 13. One end of the reciprocating motor 3 is flush with the outer end of the support beam 13.

[0030] Specifically, multiple support columns 12 provide support for the extrusion table 1, and support beam 13 reinforces the support columns 12 and provides support for the reciprocating motor 3. Two reciprocating motors 3 are symmetrically arranged on the support beam 13.

[0031] A drive rod 31 is provided at the center of the outer end of the reciprocating motor 3. A vertical rod 32 is provided at the other end of the drive rod 31. A connecting rod 33 is provided at the other end of the vertical rod 32. Push rods 34 are provided at both ends of the connecting rod 33. The push rods 34 are perpendicular to the drive rod 31. The other end of the push rods 34 is connected to the extrusion plate 4.

[0032] Specifically, the reciprocating motor 3 drives the drive rod 31 to reciprocate and extend, thereby driving the upright rod 32 and the connecting rod 33 to move synchronously. The movement of the connecting rod 33 drives the push rod 34 to move laterally, so that the push rod 34 moves parallel to the drive rod 31. The movement of the push rod 34 drives the extrusion plate 4 to move inside the extrusion chamber 15, extruding the colloid inside the extrusion chamber 15.

[0033] A flow guide platform 42 is provided at the center of the top surface of the partition plate 41, and the length of the flow guide platform 42 is the same as the length of the guide layer 14.

[0034] Specifically, the cross-section of the guide platform 42 is triangular, which facilitates the flow of the colloid inside the extrusion platform 1 to the interior of the extrusion chamber 15.

[0035] The extrusion table 1 has discharge pipes 2 on both sides, which are connected to the extrusion table 1. The discharge pipes 2 on both sides of the extrusion table 1 are symmetrical. A pair of discharge pipes 2 are provided on one side of the extrusion table 1. The discharge pipes 2 on one side of the extrusion table 1 are symmetrical with respect to the partition plate 41. The side of the discharge pipe 2 coincides with the side of the partition plate 41, and the bottom edge of the discharge pipe 2 coincides with the bottom edge of the extrusion chamber 15.

[0036] Specifically, during the extrusion process, the material inside the extrusion chamber 15 is extruded outward from the discharge pipe 2. The side of the discharge pipe 2 coincides with the side of the partition plate 41, and the bottom edge of the discharge pipe 2 coincides with the bottom edge of the extrusion chamber 15, which facilitates the complete discharge of the colloid inside the extrusion chamber 15.

[0037] An extrusion platform 22 is provided on the inner top surface of the discharge pipe 2. One end of the extrusion platform 22 is flush with the outer end of the discharge pipe 2. The height of the extrusion platform 22 is half the inner height of the discharge pipe 2. The other end of the extrusion platform 22 is an inclined surface.

[0038] Specifically, the inclined surface on the extrusion platform 22 facilitates the outward discharge of the colloid and reduces the diameter of the colloid discharge port, allowing for further extrusion of the colloid.

[0039] An installation groove 23 is provided on the outer end of the extrusion table 22. Multiple telescopic seats 24 are evenly arranged on the inner end of the installation groove 23. A telescopic rod 25 is provided inside the telescopic seat 24. A cover 21 is vertically arranged on the other end of the telescopic rod 25. The shape and size of the cover 21 are the same as the shape and size of the end face of the discharge pipe 2.

[0040] Specifically, by squeezing the colloid, the colloid is squeezed into the discharge pipe 2. The squeezed colloid pushes the cap 21 to open and discharge the colloid. The movement of the cap 21 drives the telescopic rod 25 to move inside the telescopic seat 24, so as to realize the lateral movement of the cap 21.

[0041] A return spring 26 is provided on the end face of the telescopic seat 24. The return spring 26 is located on the outside of the telescopic rod 25, and the other end of the return spring 26 is connected to the inner wall of the cover 21.

[0042] Specifically, the resetting spring 26 pulls the cover 21 to move, so that when the reciprocating motor 3 does not squeeze the colloid during the reciprocating motion, the cover 21 closes the discharge pipe 2 under the action of the resetting spring 26.

[0043] During operation, the colloid slowly enters the guide layer 14 from the extrusion table 1. Under the action of the partition plate 41 and the guide table 42, the colloid enters the extrusion chamber 15 and is separated. The reciprocating motor 3 is started, driving the drive rod 31 to reciprocate, causing the push rod 34 to reciprocate synchronously. The push rod 34 drives the extrusion plate 4 to move inside the extrusion chamber 15. The extrusion plate 4 cooperates with the partition plate 41 to extrude the two parts of colloid inside the extrusion chamber 15 and extrude them into the discharge pipe 2. The colloid is discharged... While applying pressure to pipe 2, it pushes the cap 21 to move, causing the colloid to be discharged from the discharge pipe 2. When push rod 34 drives extrusion chamber 15 to move in the opposite direction, it increases the space between extrusion plate 4 and partition plate 41. At the same time, the pressure of the colloid on cap 21 is reduced, so that the elastic force of return spring 26 is greater than the pushing force of the colloid on cap 21, causing cap 21 to seal the discharge pipe 2 again, preventing the discharge of unextruded colloid. During the reciprocating extrusion of colloid by extrusion plate 4, the extrusion effect of colloid is improved.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
