Description

Technical Field

[0001] The utility model belongs to the technical field of pressure plate structures, and in particular relates to a pressure plate structure for a glue coating machine. Background Art

[0002] The pressure plate glue coating machine, also known as the pressure plate hot melt glue machine or PUR hot melt glue machine, is mainly used to heat the solid PUR hot melt glue into liquid, and apply the liquid hot melt glue to the object to be bonded through specific equipment. In the existing pressure plate glue coating machine, the gap between the pressure plate and the inner wall of the glue barrel needs to be sealed by a sealing rubber ring, but this method has the following disadvantages: first, the resistance is large when the pressure plate is moved upward, which increases the wear of the sealing rubber ring; second, as the sealing rubber ring wears, the sealing effect decreases, and the sealing rubber ring needs to be replaced, and the service life is not long enough. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a pressure plate structure for a glue coating machine, which improves the sealing performance. Even if the first annular sealing rubber ring and the second annular sealing rubber ring are worn due to long-term use, there is no need to worry about the sealing effect being reduced. The friction force generated during the upward movement of the pressure plate body is reduced, the smoothness of the movement is improved, the wear of the first annular sealing rubber ring and the second annular sealing rubber ring is reduced, and the service life of the first annular sealing rubber ring and the second annular sealing rubber ring is increased.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a pressure plate structure for a glue coating machine, comprising a glue barrel body, a pressure plate body inserted into the interior of the glue barrel body, a first sealing installation groove and a second sealing installation groove are provided on the side of the pressure plate body, a first annular air bag is provided inside the first sealing installation groove, and a second annular air bag is provided inside the second sealing installation groove, a pipeline passage is opened between the top of the pressure plate body and the first sealing installation groove and the second sealing installation groove, a first gas pipeline and a second gas pipeline are provided inside the pipeline passage, the tops of the first gas pipeline and the second gas pipeline are connected to an electrically controlled three-way valve, the top of the electrically controlled three-way valve is connected to an air pump, a first annular sealing rubber ring is embedded in the inner side of the first sealing installation groove, and a second annular sealing rubber ring is embedded in the inner side of the second sealing installation groove.

[0005] The beneficial effects of the utility model are as follows: the device supports the first annular sealing rubber ring and the second annular sealing rubber ring through the first annular airbag and the second annular airbag with adjustable pressure, so that the first annular sealing rubber ring and the second annular sealing rubber ring can be ensured to be in close contact with the barrel body of the rubber barrel, and the first annular airbag, the second annular airbag, the first annular sealing rubber ring and the second annular sealing rubber ring cooperate to fill the first sealing installation groove and the second sealing installation groove, thereby improving the sealing performance. Moreover, due to the arrangement of the first annular airbag and the second annular airbag, even if the first annular sealing rubber ring and the second annular sealing rubber ring are worn out due to long-term use, there is no need to worry about a decrease in the sealing effect. When the rubber material in the barrel body of the rubber barrel is used up, the first annular airbag and the second annular airbag can be deflated to release the support for the first annular sealing rubber ring and the second annular sealing rubber ring. At this time, the first annular sealing rubber ring and the second annular sealing rubber ring are relaxed, thereby reducing the friction force generated during the upward movement of the pressure plate main body, thereby improving the smoothness of the movement and reducing the wear of the first annular sealing rubber ring and the second annular sealing rubber ring, thereby improving the service life of the first annular sealing rubber ring and the second annular sealing rubber ring.

[0006] As a further improvement of the above technical solution: the first annular sealing rubber ring is located outside the first annular airbag, and the second annular sealing rubber ring is located outside the second annular airbag.

[0007] To facilitate the control of the air pump operation:

[0008] As a further improvement of the above technical solution: pressure sensors are provided inside the first annular airbag and the second annular airbag.

[0009] The beneficial effect of this improvement is that the pressure sensor is used to monitor the internal pressure of the first annular airbag and the second annular airbag in real time, thereby helping the staff to understand the internal air pressure of the first annular airbag and the second annular airbag in order to control the operation of the air pump.

[0010] In order to inflate the first annular airbag and the second annular airbag respectively:

[0011] As a further improvement of the above technical solution: one end of the first gas pipeline is connected to the first annular airbag, and one end of the second gas pipeline is connected to the second annular airbag.

[0012] The beneficial effect of this improvement is that the first gas pipeline and the second gas pipeline are used to inflate the first annular airbag and the second annular airbag respectively.

[0013] To support the pump:

[0014] As a further improvement of the above technical solution: a bracket is connected between the air pump and the pressure plate body.

[0015] The beneficial effect of this improvement is that the bracket is used to support the air pump.

[0016] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

When the rubber in the rubber barrel body 1 is used up, the first annular airbag 5 and the second annular airbag 6 can be deflated to release the support for the first annular sealing rubber ring 13 and the second annular sealing rubber ring 14. At this time, the first annular sealing rubber ring 13 and the second annular sealing rubber ring 14 are relaxed, which reduces the friction generated during the upward movement of the pressure plate body 2, improves the smoothness of the movement, reduces the wear of the first annular sealing rubber ring 13 and the second annular sealing rubber ring 14, and increases the service life of the first annular sealing rubber ring 13 and the second annular sealing rubber ring 14.
