Description

Technical Field

[0001] This utility model relates to the field of adhesive degassing, and in particular to an online vacuum degassing mechanism. Background Technology

[0002] Currently, glue dispensing is involved in various industrial production processes, typically automated by glue dispensing equipment. This equipment is connected to a glue supply system to provide glue to the dispensing unit. However...

[0003] In existing adhesive feeding systems, a large number of air bubbles often exist in the adhesive before feeding. When there are too many air bubbles in the adhesive, it will affect the dispensing quality of the subsequent adhesive.

[0004] Therefore, the glue needs to be degassed before use. However, existing degassed equipment degassed the glue in a separate bucket, which required a glue pump to supply the glue, resulting in high costs and large space requirements. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an online vacuum degassing mechanism to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an online vacuum degassing mechanism, including a base, one end of which is connected to a valve and an adhesive inlet, a vacuum chamber is provided on the top of the base, an upper shell is provided on the top of the vacuum chamber, a vacuum tube is provided on one side of the back of the upper shell, the vacuum tube is connected to the vacuum chamber for connecting a vacuum pump to discharge the gas from the vacuum chamber, and an adhesive dispensing component is movably inserted into the middle of the upper shell.

[0007] Preferably, the upper housing has a movable chamber in the middle, and the dispensing assembly includes a pressure cylinder, a dispensing tube, and a lifting block. The dispensing tube is movably inserted into the upper housing and its bottom extends through the movable chamber to the top of the vacuum chamber. The pressure cylinder is fixedly connected to the bottom of the dispensing tube, and the sealing block is fixedly installed in the middle of the dispensing tube and movably placed in the movable chamber.

[0008] Preferably, a vacuum sensor is provided on the other side of the back of the upper housing, and the detection end of the vacuum sensor is connected to the inside of the vacuum cavity.

[0009] Preferably, a magnetic sensor is provided at the center of the front end of the upper housing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention delivers glue into a vacuum chamber through a valve and glue inlet, and uses a vacuum tube and vacuum pump to evacuate the glue inside the vacuum chamber, thus achieving degassing treatment. Finally, the glue dispensing component is driven downward by a lifting device connected to the glue dispensing component to discharge the glue. This replaces the previous method of stirring and degassing in a separate glue bucket, eliminating the need for a glue pump, reducing costs, and taking up less space. Attached Figure Description

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0016] This utility model provides an online vacuum degassing mechanism, such as Figure 1-2 As shown, it includes a base 1, one end of which is connected to a valve 2 and an adhesive inlet 3. A vacuum chamber 4 is provided on the top of the base 1, and an upper shell 5 is provided on the top of the vacuum chamber 4. A vacuum tube 6 is provided on one side of the back of the upper shell 5. The vacuum tube 6 is connected to the vacuum chamber 4 and is used to connect a vacuum pump to discharge the gas from the vacuum chamber 4. An adhesive dispensing assembly 8 is movably inserted into the middle of the upper shell 5.

[0017] The glue is delivered into the vacuum chamber 4 through valve 2 and glue inlet 3. The glue inside the vacuum chamber 4 is evacuated using the vacuum tube 6 and vacuum pump to remove bubbles. Finally, the glue is discharged by the lifting device connected to the glue dispensing assembly 8, which moves downwards. This replaces the previous method of stirring and degassing in a separate glue bucket, eliminating the need for a glue pump. This not only reduces costs but also saves space.

[0018] The upper housing 5 has a movable chamber 10 in the middle. The glue dispensing assembly 8 includes a pressure cylinder 81, a glue dispensing tube 82 and a lifting block. The glue dispensing tube 82 is movably inserted into the upper housing 5 and its bottom extends through the movable chamber 10 to the top of the vacuum chamber 4. The pressure cylinder 81 is fixedly connected to the bottom of the glue dispensing tube 82. The sealing block 83 is fixedly installed in the middle of the glue dispensing tube 82 and is movably placed in the movable chamber 10.

[0019] The top of the dispensing tube 82 is connected to a lifting device. When dispensing glue, the dispensing tube 82 drives the pressure cylinder 81 to descend, squeezing out the water inside the vacuum chamber 4. The sealing block 83 is used for sealing and also for limiting the movement path of the vacuum chamber 4 to prevent excessive rising or falling.

[0020] A vacuum sensor 7 is provided on the other side of the back of the upper housing 5. The detection end of the vacuum sensor 7 is connected to the inside of the vacuum chamber 4.

[0021] A magnetic sensor 9 is provided at the front center of the upper housing 5.

[0022] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0023] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
