Description

Technical Field

[0001] The utility model belongs to the technical field of glue coating, and in particular relates to a one-way pressing plate glue storage device. Background Art

[0002] During the gluing operation, the existing pump directly immerses the feed pipe into the glue liquid and sucks the glue liquid into the pump through the feed pipe. However, when the gluing operation is suspended, the glue liquid in the pump and the feed pipe will flow back into the barrel under the action of its own gravity, affecting the subsequent gluing operation and thus affecting the gluing quality. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art and provides a one-way pressure plate glue storage device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A one-way pressure plate glue storage device comprises a pressure plate, a diaphragm, a support sheet and a glue barrel.

[0006] The pressure plate, diaphragm and support plate are all placed in the glue barrel and are coaxially arranged with the glue barrel; the outer side surface of the pressure plate and the inner wall of the glue barrel form a sliding friction pair, a pressure plate glue outlet hole is opened at the center position of the pressure plate, and two air holes are opened on both sides of the pressure plate glue outlet hole, and an air pipe is fixed in each air hole; the diaphragm is located below the pressure plate, and the outer edge of the diaphragm is fixed to the pressure plate, a diaphragm glue outlet hole is opened at the center position of the diaphragm, and circular holes aligned with the two air holes are opened on both sides of the diaphragm glue outlet hole; except for the part fixed to the pressure plate, the rest of the diaphragm A gap is provided with the bottom surface of the pressure plate; the support plate is located below the diaphragm, and the outer edge of the support plate is fixed to the outer edge of the diaphragm, and a plurality of support plate glue outlet hole groups uniformly distributed along the circumferential direction are provided on the support plate, and the support plate glue outlet hole group is composed of a plurality of support plate glue outlet holes uniformly distributed along the radial direction, and the distance between the support plate glue outlet hole closest to the center of the support plate in each support plate glue outlet hole group and the center of the support plate is greater than the radius of the diaphragm glue outlet hole, and the support plate is also provided with circular hole two aligned with the two circular holes one respectively; one end of each air pipe away from the pressure plate passes through a circular hole one and is fixed on a circular hole two.

[0007] Preferably, a plurality of annular grooves arranged at vertical intervals are formed on the outer side surface of the pressure plate, and a sealing ring is embedded in each annular groove.

[0008] Preferably, the diameter of the glue outlet hole of the diaphragm is smaller than the diameter of the glue outlet hole of the pressure plate.

[0009] The utility model has the following beneficial effects:

[0010] 1. During the use of the utility model, when the pump starts to work, the air pressure in the space below the support sheet in the glue barrel is greater than the air pressure in the space above the diaphragm in the glue barrel, thereby causing the diaphragm to deform upward and open the liquid inlet holes of each support sheet, thereby realizing the delivery of the glue. When the pump stops working, the diaphragm presses on the support sheet and closes the liquid inlet holes of each support sheet, thereby preventing the glue in the pump and the glue outlet pipe from flowing back into the glue barrel, thus realizing a one-way function and avoiding the phenomenon that the subsequent glue coating operation is affected by the glue in the pump and the glue outlet pipe flowing back into the glue barrel, thereby ensuring the glue coating quality.

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is a one-way pressure plate glue storage device, which includes a pressure plate 1, a diaphragm 2, a support sheet 3 and a glue barrel 5.

[0018] The pressure plate 1, the diaphragm 2 and the support plate 3 are all placed in the glue barrel 5 and are coaxially arranged with the glue barrel 5. The glue barrel 5 is used to store glue; the outer side surface of the pressure plate 1 and the inner wall of the glue barrel 5 form a sliding friction pair, a pressure plate glue outlet hole 8 is opened at the center position of the pressure plate 1, and two air holes 9 are opened on both sides of the pressure plate glue outlet hole 8, and an air pipe 10 is fixed in each air hole 9; the diaphragm 2 is located below the pressure plate 1, and the outer edge position of the diaphragm 2 is fixed to the pressure plate 1, a diaphragm glue outlet hole 7 is opened at the center position of the diaphragm 2, and circular holes 1 aligned with the two air holes 9 are opened on both sides of the diaphragm glue outlet hole 7; except for the diaphragm 2 fixed to the pressure plate 1 The support sheet 3 is located below the diaphragm 2, and the outer edge of the support sheet 3 is fixed to the outer edge of the diaphragm 2. The support sheet 3 is provided with a plurality of support sheet glue outlet holes uniformly distributed along the circumferential direction. The support sheet glue outlet holes are composed of a plurality of support sheet glue outlet holes 6 arranged along the radial direction. The distance between the support sheet glue outlet hole 6 closest to the center of the support sheet 3 in each support sheet glue outlet hole group and the center of the support sheet 3 is greater than the radius of the diaphragm glue outlet hole 7. The support sheet 3 is also provided with circular holes 2 aligned with the two circular holes 1 respectively. The end of each air pipe 10 away from the pressure plate 1 passes through a circular hole 1 and is fixed to a circular hole 2. Among them, the diaphragm 2 is made of flexible material, and the pressure plate liquid outlet hole 8 can be connected to various pumps.

[0019] As a preferred embodiment, a plurality of annular grooves arranged at upper and lower intervals are provided on the outer surface of the pressure plate 1, and a sealing ring 4 is embedded in each annular groove. The sealing ring 4 is used to ensure the sealing between the outer side surface of the pressure plate 1 and the inner wall of the glue barrel 5.

[0020] As a preferred embodiment, the diameter of the glue outlet hole 7 of the diaphragm is smaller than the diameter of the glue outlet hole 8 of the pressure plate.

[0021] The working principle of the one-way pressure plate glue storage device of the utility model is as follows:

[0022] The glue barrel 5 is filled with glue, and the pressure plate 1, diaphragm 2 and support plate 3 are all located above the glue liquid surface. In the initial state, the pressure plate glue outlet hole 8 and the two air pipes 10 are blocked, and the diaphragm 2 covers the glue outlet holes 6 of each support plate.

[0023] Before the glue coating operation, the glue outlet hole 8 of the pressure plate is opened, the two air pipes 10 are in a closed state, and the glue outlet hole 8 of the pressure plate is connected to the pump through the glue outlet pipe; when the glue coating operation is carried out, the pump starts to work, and the pressure of the space above the diaphragm 2 in the glue barrel 5 decreases, and the air pressure in the space below the support sheet 3 in the glue barrel 5 is greater than the air pressure in the space above the diaphragm 2 in the glue barrel 5, thereby causing the diaphragm 2 to deform upward and separate from the support sheet 3, so that the liquid inlet holes 6 of each support sheet are opened, and the space below the support sheet 3 in the glue barrel 5 and the glue outlet hole 8 of the pressure plate pass through the space between the diaphragm 2 and the support sheet 3, the liquid inlet holes 6 of each support sheet, the glue outlet hole 7 of the diaphragm and the diaphragm 2. It is connected to the channel formed by the gap on the bottom of the pressure plate 1. As the air pressure in the glue barrel 5 decreases, the atmospheric pressure drives the pressure plate 1 to descend, and at the same time, the glue is pressed into the glue outlet hole 8 of the pressure plate through the channel and is pumped out through the glue outlet pipe; when the gluing operation is stopped, the pump stops working, the pressure plate 1 stops descending, and the center position of the diaphragm 2 is pressed on the support plate 3 under the action of its own gravity and the gravity of the glue above the diaphragm 2, and returns to its original state. The liquid inlet holes 6 of each support plate are closed, and the space below the support plate 3 in the glue barrel 5 is disconnected from the glue outlet hole 8 of the pressure plate, so that the glue in the pump and the glue outlet pipe cannot flow back into the glue barrel 5, thereby realizing the one-way function.

[0024] When it is necessary to replace the glue barrel 5 or replenish glue into the glue barrel 5, the two air pipes 10 are opened, the glue outlet hole 8 of the pressure plate is in a closed state, the two air pipes 10 are connected to the air pump through pipelines, the air pump works, and inflates the space below the support plate 3 in the glue barrel 5 through the pipeline and the two air pipes 10. The air pressure in the space below the support plate 3 in the glue barrel 5 increases, thereby pushing the pressure plate 1 to drive the diaphragm 2 and the support plate 3 to move upward until the pressure plate 1, the diaphragm 2 and the support plate 3 are separated from the glue barrel 5; then replace the glue barrel 5 or replenish glue into the glue barrel 5, take out a new glue barrel 5 filled with glue or complete the work of replenishing glue in the glue barrel 5, install the pressure plate 1, the diaphragm 2 and the support plate 3 in the glue barrel 5, remove the pipeline, and then press the pressure plate 1 downward by external force to discharge the excess gas in the glue barrel 5 from the two air pipes 10, and finally close the two air pipes 10 to complete the replacement of the glue barrel 5 or the work of replenishing glue.
