Description

Technical Field

[0001] This utility model relates to the field of sealant extrusion technology, and more specifically, to an extrusion apparatus for producing silane-modified epoxy sealant. Background Technology

[0002] Silane-modified epoxy sealant is a novel sealing material with excellent comprehensive performance. Based on epoxy resin, it is modified by introducing silane coupling agents. This process retains the excellent adhesion, mechanical strength, and chemical resistance of epoxy resin while enhancing its flexibility, weather resistance, and adhesion to various substrates through the introduction of silane. During curing, this sealant forms a dense cross-linked network structure, exhibiting excellent waterproof, moisture-proof, dustproof, and sealing effects. It is widely used in construction, automotive, electronics, and aerospace industries, and can be applied in various scenarios such as door and window installation, vehicle body sealing, and electronic component encapsulation. It effectively prevents external environmental factors from corroding internal structures, extending the service life of equipment or components. Furthermore, it is easy to apply, cures quickly, and has strong environmental adaptability, making it a high-performance sealing material with great application potential.

[0003] Extruders are important equipment for producing silane-modified epoxy sealants. However, most existing extruders have fixed extrusion specifications during operation. If the extrusion specifications need to be adjusted, the machine must be stopped first, and then the extruder head must be replaced, which seriously affects the extrusion efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an extrusion device for the production of silane-modified epoxy sealant.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an extrusion device for producing silane-modified epoxy sealant, comprising an extruder body, an extrusion tube fixedly connected to one end of the extruder body, a discharge main tube connected to the extrusion tube, a ring sleeve rotatably connected to the discharge main tube, a switching port opened on the discharge main tube, the switching port being located inside the ring sleeve, and multiple discharge auxiliary tubes connected to the ring sleeve.

[0006] Preferably, an external toothed ring is fixedly connected to the ring sleeve, a drive gear is meshed on the external toothed ring, the drive gear is fixedly connected to the output shaft of the motor, and the motor is mounted on the extruder body.

[0007] Preferably, a ball is rotatably connected to the inside of the discharge main pipe at the end away from the extrusion pipe. The ball has a through groove and a vertical shaft is fixedly connected to it. The end of the vertical shaft away from the ball passes through the side wall of the discharge main pipe.

[0008] Preferably, a bevel gear is fixedly connected to the vertical shaft, a bevel gear is meshed with a bevel ring, and the bevel ring is fixedly connected to multiple discharge auxiliary pipes.

[0009] Preferably, a first sealing layer is provided between the sphere and the discharge main pipe.

[0010] Preferably, a second sealing layer is provided between the ring sleeve and the discharge main pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When different specifications of sealant need to be discharged, rotate the ring and align the required discharge sub-pipe with the switching port. At this time, the sealant in the discharge main pipe will pass through the switching port and enter the discharge sub-pipe, and finally be discharged through the extruder at one end of the discharge sub-pipe. This allows for adjustment of the sealant extrusion specifications without stopping the machine to replace the extruder, effectively improving extrusion efficiency.

[0013] 2. When the discharge secondary pipe is aligned with the switching port, the ball can be rotated by the vertical shaft, so that the axis of the through groove is perpendicular to the axis of the discharge main pipe. At this time, the ball blocks the discharge main pipe, and all the sealant in the discharge main pipe enters the discharge secondary pipe.

[0023] Reference Figures 1 to 3 This utility model provides a technical solution: an extrusion device for producing silane-modified epoxy sealant, comprising an extruder body 1, an extrusion pipe 2 fixedly connected to one end of the extruder body 1, and a discharge main pipe 3 connected to the extrusion pipe 2, such as... Figure 1 The silane-modified epoxy sealant in the extruder body 1 is extruded through the extrusion tube 2 and enters the discharge main tube 3. The discharge main tube 3 is rotatably connected to the ring sleeve 4. The discharge main tube 3 has a switching port 5, which is located inside the ring sleeve 4. The ring sleeve 4 is connected to multiple discharge auxiliary tubes 6, and extrusion heads of different specifications can be installed at the ends of the multiple discharge auxiliary tubes 6 away from the ring sleeve 4.

[0024] like Figure 1 and Figure 2The ring sleeve 4 seals the switching port 5. At this time, the sealant in the discharge pipe 3 is discharged directly through the end of the discharge pipe 3 away from the extrusion pipe 2.

[0025] like Figure 3 When different specifications of sealant need to be discharged, rotate the ring sleeve 4 and align the required discharge sub-pipe 6 with the switching port 5. At this time, the sealant in the discharge main pipe 3 will pass through the switching port 5 and enter the discharge sub-pipe 6, and finally be discharged through the extruder at one end of the discharge sub-pipe 6. This adjusts the extrusion specifications of the sealant without stopping the machine to replace the extruder, effectively improving the extrusion efficiency.

[0026] Specifically, an external toothed ring 7 is fixedly connected to the ring sleeve 4, a drive gear 8 is meshed on the external toothed ring 7, the drive gear 8 is fixedly connected to the output shaft of the motor 9, and the motor 9 is mounted on the extruder body 1;

[0027] like Figure 1 and Figure 2 The motor 9 drives the drive gear 8 to rotate, and the drive gear 8 can then drive the ring sleeve 4 to rotate through the meshing external gear ring 7.

[0028] Specifically, a ball 10 is rotatably connected to the end of the discharge main pipe 3 away from the extrusion pipe 2. A through groove 11 is opened on the ball 10. A vertical shaft 12 is fixedly connected to the ball 10. The end of the vertical shaft 12 away from the ball 10 passes through the side wall of the discharge main pipe 3.

[0029] like Figure 3 When the axis of the through groove 11 is parallel to the axis of the discharge pipe 3, the sealant in the discharge pipe 3 can pass through the through groove 11 and be discharged.

[0030] When the discharge sub-pipe 6 is aligned with the switching port 5, the ball 10 can be rotated by the vertical shaft 12, so that the axis of the through groove 11 is perpendicular to the axis of the discharge main pipe 3. At this time, the ball 10 blocks the discharge main pipe 3, and all the sealant in the discharge main pipe 3 enters the discharge sub-pipe 6.

[0031] Specifically, a bevel gear 13 is fixedly connected to the vertical shaft 12, a bevel gear ring 14 is meshed on the bevel gear 13, and the bevel gear ring 14 is fixedly connected to multiple discharge auxiliary pipes 6;

[0032] like Figure 1 and Figure 3 The ring sleeve 4 can drive the multiple discharge sub-pipes 6 on it to rotate. The multiple discharge sub-pipes 6 together drive the bevel gear ring 14 to rotate. The bevel gear ring 14 can then drive the vertical shaft 12 to rotate through the meshing bevel gear 13, so that when the discharge sub-pipe 6 is aligned with the switching port 5, the axis of the through groove 11 is perpendicular to the axis of the discharge main pipe 3.

[0033] Specifically, a first sealing layer is provided between the sphere 10 and the discharge main pipe 3.

[0034] Specifically, a second sealing layer is provided between the ring sleeve 4 and the discharge main pipe 3.

[0035] Working principle: When different specifications of sealant need to be discharged, the motor 9 drives the drive gear 8 to rotate. The drive gear 8 can drive the ring sleeve 4 to rotate through the meshing external gear ring 7. The ring sleeve 4 can drive the multiple discharge sub-pipes 6 on it to rotate, so that the required discharge sub-pipe 6 is aligned with the switching port 5. At this time, the sealant in the discharge main pipe 3 will pass through the switching port 5 and enter the discharge sub-pipe 6, and finally be discharged through the extrusion head at one end of the discharge sub-pipe 6, thereby adjusting the extrusion specifications of the sealant.

[0036] It should be noted that all electrical components appearing in this application are connected to an external main controller and 220V AC mains power.
