Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to an alkoxysilane-terminated resin filling machine. Background Technology

[0002] Alkoxysilane-terminated resins are mainly used in the fields of electronic component encapsulation, coatings, adhesives, and composite materials. After production, they need to be filled using a filling machine.

[0003] During manual operation, the operator needs to judge whether the required capacity has been reached based on the amount of resin filled and manually close the discharge valve. Although this process is simple and easy, it also has some significant drawbacks. First, because it relies on the operator's experience and visual observation, especially when the resin filling speed is fast or the resin transparency is not high, the accuracy of manual judgment will be greatly reduced, and it is easy to overfill or underfill. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an alkoxysilane-terminated resin filling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Reference Figures 1-3 An alkoxysilane-terminated resin filling machine includes a fixed frame 2. A material cylinder 1 is bolted to the top of the fixed frame 2. A stirring assembly is provided inside the material cylinder 1. The stirring assembly includes a connecting shaft 3, which is rotatably connected to the inner wall of the top of the material cylinder 1. A motor is bolted to the outer wall of the top of the material cylinder 1. One end of the motor output shaft passes through the material cylinder 1 and is fixed to the connecting shaft 3. Multiple stirring plates 19 are bolted to the outer side of the connecting shaft 3. When it is necessary to stir the alkoxysilane-terminated resin in the material cylinder 1, the motor is started. The rotation of the motor causes the connecting shaft 3 to drive the stirring plates 19 to rotate, thereby stirring the alkoxysilane-terminated resin in the material cylinder 1. This helps to ensure that the alkoxysilane-terminated resin is mixed evenly before filling, avoiding the problem of inconsistent product quality due to resin sedimentation or uneven composition.

[0023] Specifically, a first discharge pipe 5 is fixedly connected to the bottom of the material cylinder 1, and a second discharge pipe 7 is slidably connected inside the first discharge pipe 5. The second discharge pipe 7 consists of a round pipe and a conical pipe at the bottom. A connecting assembly is provided between the first discharge pipe 5 and the second discharge pipe 7. The connecting assembly includes a second cylinder 10. The second cylinder 10 is fixed to the outer wall of one side of the first discharge pipe 5 by bolts. Both sides of the bottom end of the second discharge pipe 7 extending out of the outer wall of the first discharge pipe 5 are welded with protrusions 16, and one end of the piston rod of the second cylinder 10 is fixed to a protrusion 16 at the corresponding position at the bottom. A second telescopic rod 17 is fixed to the outer wall of one side of the first discharge pipe 5 by bolts. The extended end of the second telescopic rod 17 is fixed to another protrusion 16 at the corresponding position at the bottom. When the second cylinder 10 extends, the second discharge pipe 7 moves downward along the first discharge pipe 5. At this time, the length of the second discharge pipe 7 extending out of the first discharge pipe 5 is changed to adapt to different filling requirements.

[0024] It should be noted that the conical tube portion at the bottom of the second discharge pipe 7 extends out of the first discharge pipe 5. Both the conical tube portions at the bottom of the first discharge pipe 5 and the second discharge pipe 7 have two grooves. A second baffle 18 is slidably connected in the two grooves on the first discharge pipe 5, and a first baffle 15 is slidably connected in the two grooves on the second discharge pipe 7. The ends of the first baffle 15 and the second baffle 18 that pass through the grooves are fixed with a fixing rod 14 by bolts. The bottom of the material cylinder 1 is provided with a pushing assembly that pushes the fixing rod 14 to move. The pushing assembly can make the second baffle 18 block the first discharge pipe 5 and the first baffle 15 block the second discharge pipe 7, thus controlling the opening and closing of the first discharge pipe 5 and the second discharge pipe 7.

[0025] In this utility model, the pushing assembly includes a first cylinder 8, which is bolted to the bottom outer wall of the material cylinder 1. A first telescopic rod 4 is bolted to the bottom outer wall of the material cylinder 1. The extended end of the first telescopic rod 4 and the piston rod of the first cylinder 8 are both bolted to a fixing plate 11. Connecting rods 12 are bolted to both sides of the fixing plate 11. A push block 6 is bolted between two adjacent connecting rods 12. The first telescopic rod 4 can assist in guiding the movement of the push block 6. The top and bottom of the push block 6 are provided with inclined surfaces 13, and the inclined surfaces 13 are in contact with the fixing rod 14. The first baffle 15 and the second... Tension springs 20 are welded to both sides of the baffle 18, and the tension springs 20 are fixed to the second discharge pipe 7 and the first discharge pipe 5 at the corresponding positions. The first cylinder 8 retracts, driving the fixed plate 11 to move. The fixed plate 11 drives the push block 6 to move upward through the connecting rod 12, so that the inclined surface 13 at the top of the push block 6 presses the fixed rod 14 on the second baffle 18, so that the second baffle 18 moves to both sides along the sliding groove and the housing 9 connected to it, and the tension springs 20 extend. At this time, the top of the first discharge pipe 5 is in an open state, and the bottom of the second discharge pipe 7 is in a blocked state. The material in the material cylinder 1 enters the first discharge pipe 5 and the second discharge pipe 7.

[0026] Both sides of the outer walls of the first discharge pipe 5 and the second discharge pipe 7 are welded with housings 9, and the housings 9 are connected to the corresponding sliding grooves. The housings 9 serve to protect and guide the sliding of the first baffle 15 and the second baffle 18. The two second baffles 18 contact each other and block the first discharge pipe 5, and the two first baffles 15 contact each other and block the second discharge pipe 7. After feeding is completed, the first cylinder 8 extends, causing the push block 6 to move downward. Under the pulling force of the tension spring 20, the second baffle 18 is reset. The top of the first discharge pipe 5 is then resealed, and the pusher 6 continues to move downward, so that the inclined surface 13 at its bottom contacts the connecting rod 12 on the first baffle 15. This causes the first baffle 15 to slide in the groove of the second discharge pipe 7, making the bottom of the second discharge pipe 7 open. At this time, the material in the space between the first discharge pipe 5 and the second discharge pipe 7 is discharged through the discharge port at the bottom of the second discharge pipe 7, allowing the material to enter the filling bottle placed at its bottom, thereby achieving quantitative filling of the material.

[0027] Working principle: When filling alkoxysilane-terminated resin, the first cylinder 8 is activated first. The first cylinder 8 retracts, driving the fixed plate 11 to move. The fixed plate 11 drives the push block 6 to move upward through the connecting rod 12, causing the inclined surface 13 at the top of the push block 6 to press the fixed rod 14 on the second baffle 18. This causes the second baffle 18 to move to both sides along the sliding groove and the housing 9 connected to it, and the tension spring 20 extends. At this time, the top of the first discharge pipe 5 is open, and the bottom of the second discharge pipe 7 is blocked. The material in the cylinder 1 enters the first discharge pipe 5 and the second discharge pipe 7. After feeding is completed, the first... When cylinder 8 extends, push block 6 moves downward. Under the tension of spring 20, second baffle 18 resets and re-closes the top of first discharge pipe 5. Then push block 6 continues to move downward, so that the inclined surface 13 at its bottom presses against the connecting rod 12 on first baffle 15, causing first baffle 15 to slide in the groove of second discharge pipe 7, making the bottom of second discharge pipe 7 open. At this time, the material in the space between first discharge pipe 5 and second discharge pipe 7 is discharged through the discharge port at the bottom of second discharge pipe 7, allowing the material to enter the filling bottle placed at its bottom, thereby realizing quantitative filling of material.

[0028] The length between the first discharge pipe 5 and the second discharge pipe 7 can also be adjusted as needed to increase the storage space for materials, thereby adjusting the discharge volume. That is, the second cylinder 10 is activated, and the second cylinder 10 extends to move the second discharge pipe 7 downward along the first discharge pipe 5. At this time, the length of the second discharge pipe 7 extending out of the first discharge pipe 5 is changed to adapt to different filling requirements.
