The fast flow rate of the sizing flowing out of the multiple telescopic tubes causes impact on the surface of the sizing and generates bubbles. Content of the Utility Model:

[0023] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense.

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] As Figures 1-5 shown, the present utility model provides the following technical solution: a sizing machine glue inlet cavity, including a glue inlet cavity 1, a baffle 2 is slidably attached inside the glue inlet cavity 1, a sealing ring 3 is fixedly sleeved on the side wall of the baffle 2 and the outer arc surface of the sealing ring 3 is attached to the inner wall of the glue inlet cavity 1, a multi-section telescopic tube 4 is fixedly connected through the baffle 2, the bottom end of the multi-section telescopic tube 4 communicates with the glue inlet cavity 1 at the bottom end of the baffle 2, the top end of the multi-section telescopic tube 4 passes through the glue inlet cavity 1 and a sealing valve is fixedly connected to the top end of the side wall, a first compression spring 9 is sleeved on the multi-section telescopic tube 4, the first compression spring 9 is arranged inside the glue inlet cavity 1 and the bottom end of the first compression spring 9 is attached to the top surface of the baffle 2, the bottom end of the multi-section telescopic tube 4 is rotationally communicated with a diversion cavity 5 attached to the bottom surface of the baffle 2, a plurality of diversion holes 6 are annularly formed on the outer wall of the diversion cavity 5, the minimum diameter sum of the plurality of diversion holes 6 is greater than the inner diameter of the bottom end of the multi-section telescopic tube 4, and the plurality of diversion holes 6 realize the diversion and deceleration of the fluid.

[0025] Please combine Figure 1As shown, when the glue injection cavity 1 needs to be injected with glue during use, first connect the output end of the external glue injection device to the multi-section telescopic tube 4, then open the sealing valve at the top of the multi-section telescopic tube 4, and operate the external glue injection device to inject the sizing agent from the output end of the external glue injection device into the multi-section telescopic tube 4, and discharge it from the bottom end of the multi-section telescopic tube 4 into the diversion cavity 5. Then, the sizing agent is diverted and transported to the glue injection cavity 1 along the diversion holes 6 on the diversion cavity 5, reducing the flow rate of the sizing agent and the impact force on the surface of the sizing agent, thereby reducing the generation of foam. As the sizing agent in the glue injection cavity 1 gradually increases, it pushes the baffle 2 to move and compress the first compression spring 9 to deform. The baffle 2 drives the multi-section telescopic tube 4 to gradually contract, and the multi-section telescopic tube 4 drives the diversion cavity 5 to move. The setting of the sealing ring 3 ensures the sealing between the glue injection cavity 1 and the baffle 2.

[0026] The diameter of the diversion hole 6 gradually increases from the center to the edge of the diversion cavity 5.

[0027] Please combine Figure 1 As shown, during use, the contact area between the sizing agent and the diversion cavity 5 is increased, and the flow rate of the sizing agent is reduced.

[0028] The longitudinal section of the diversion hole 6 is a corrugated surface.

[0029] Please combine Figure 4 As shown, during use, the flow path of the sizing agent is extended, and the flow rate of the sizing agent is reduced.

[0030] The transverse section of the diversion hole 6 is an arc surface. The diameters of the multiple diversion holes 6 are different from each other, and the sizes of the diversion holes 6 are distributed along the clockwise direction.

[0031] Please combine Figure 5 As shown, during use, the flow path of the sizing agent is extended, and the flow rate of the sizing agent is reduced. The diameters of the diversion holes 6 are different from each other, and the sizes of the diversion holes 6 are distributed along the clockwise direction, so that the reaction forces exerted by the sizing agent on the diversion cavity 5 are different, enabling the diversion cavity 5 to rotate, changing the discharge position of the diversion holes 6, reducing the impact on the surface of the sizing machine at the same position, and thus reducing the generation of foam.

[0032] An inflation cavity 10 is annularly formed inside the sealing ring 3. The top end of the inflation cavity 10 is connected to an air injection assembly fixedly connected to the baffle 2, and the air injection assembly can perform an inflation operation on the inflation cavity 10.

[0033] The air injection assembly includes multiple inflation air bags 11 communicated with the inflation cavity 10. The inflation air bags 11 are fixed on the top surface of the baffle 2. A retaining ring 12 is provided directly above the multiple inflation air bags 11. The top surface of the retaining ring 12 is annularly and fixedly connected with multiple multi-section telescopic rods 13. The top ends of the multi-section telescopic rods 13 are fixedly connected to the inner surface of the glue injection cavity 1, and a second compression spring 14 is sleeved on the multi-section telescopic rods 13.

[0034] Please refer to Figure 1 As shown, during use, the baffle 2 drives the sealing ring 3 to slide repeatedly in the glue inlet cavity 1. The sealing ring 3 is worn after long-term use, resulting in the inability to seal between the glue inlet cavity 1 and the baffle 2. When injecting glue into the glue inlet cavity 1, the glue applicator gradually increases the force to push the baffle 2 to move. The baffle 2 drives the inflatable airbag 11 to move gradually closer to the retaining ring 12. The retaining ring 12 pushes the inflatable airbag 11 to work, and the inflatable airbag 11 inflates the inflatable cavity 10. The inflation of the inflatable cavity 10 makes the sealing ring 3 fit against the inner wall of the glue inlet cavity 1 again to ensure the sealing between the glue inlet cavity 1 and the baffle 2. When the sealing ring 3 is not worn, the upward moving inflatable airbag 11 pushes the retaining ring 12 to move and compress the second compression spring 14, causing deformation.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
