Description

A formaldehyde-free adhesive filling assembly Technical Field

[0001] This utility model belongs to the technical field of adhesive production equipment, specifically relating to a filling component for formaldehyde-free adhesives. Background Technology

[0002] Adhesive is a common type of adhesive that is widely used in various fields. After the adhesive is produced, it needs to be filled into containers.

A controller is installed on the outside of the glue container, and the dispensing control valve, filling control valve, and level sensor are all connected to the controller. While this type of filling machine can achieve quantitative filling of glue and adjust the filling volume, its high cost makes it unsuitable for small-scale glue production enterprises.

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] Example: A formaldehyde-free adhesive filling assembly, as shown in Figures 1-2, includes two guide rods 1, with a sliding assembly between the guide rods 1. The sliding assembly includes an inlet cylinder 2 and an outlet cylinder 3. The bottom of the outlet cylinder 3 is provided with an adhesive outlet head 4. The top of both the inlet cylinder 2 and the outlet cylinder 3 is provided with a pipe connector 5. The inlet cylinder 2 and the outlet cylinder 3 are arranged side by side, with their contact surfaces being flat. The bottom flat surface of the inlet cylinder 2 is provided with an outlet 6, and the flat surface of the outlet cylinder 3 is provided with an inlet 7 corresponding to the outlet 6. The two are aligned with each other. A rubber diaphragm 8 is provided inside the outlet cylinder 3. The bottom of the rubber diaphragm 8 is fixed to the inside of the outlet cylinder 3 and completely covers the inlet 7. The flat surface of the outlet cylinder 3 around the inlet 7 is provided with a sealant groove 9. A sealing ring 10 is installed on the flat surface of the inlet cylinder 2 around the outlet 6. The position of the sealing ring 10 cooperates with the sealing groove 9.

[0015] The discharge cylinder 3 is provided with a set of guide slides 11 on both the left and right sides. The discharge cylinder 3 is slidably connected to the guide rods 1 through the guide slides 11.

[0016] The top of the feed cylinder 2 is provided with multiple air outlets 12.

[0017] The top of the discharge cylinder 3 shown is equipped with a connecting seat 13 for connecting to the cylinder.

[0018] The principle of this utility model is as follows: In use, a telescopic cylinder is set above the discharge cylinder 3 to drive the discharge cylinder 3 and the feed cylinder 2 to slide up and down on the guide rod 1. A material pipe is connected to the pipe joint 5 on the feed cylinder 2. The position of the material pipe in the discharge cylinder 3 is lower than the position of the air outlet 12, and the feed cylinder 2 is always kept full of glue. An air pipe is connected to the pipe joint 5 of the discharge cylinder 3 and connected to the solenoid valve to control the suction and pressurization of the discharge cylinder 3. During the suction process, the discharge cylinder 3 is under negative pressure, and the glue is drawn into the feed cylinder 2 through the feed port 7 of the discharge cylinder 3. During the process, the rubber diaphragm 8 will be pushed open. After the suction is completed, the rubber diaphragm 8 will be re-adhered to the inner wall of the discharge cylinder 3. When pressurizing the discharge cylinder 3, the rubber diaphragm 8 will be pushed against the inner wall of the discharge cylinder 3, and the glue inside will be squeezed out from the glue outlet 4 at the bottom.

[0019] The feed cylinder 2 and the discharge cylinder 3 are driven to slide down by the telescopic cylinder, making it easier to go deep into the filling cylinder used to hold glue.

[0020] By adjusting the pumping time in the discharge cylinder 3, the amount of glue pumped out by the discharge cylinder 3 from the feed cylinder 2 can be controlled. This can solve the problem of quantitative filling at low cost, and at the same time, the filling volume can be changed, making it convenient for small-scale enterprises to use.

[0021] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
