Technical Field

[0001] The utility model relates to an extrusion device, in particular to a high-viscosity liquid extrusion device. Background Art

[0002] Due to the viscosity characteristics of high-viscosity fluids, a press-type extrusion device is generally used for extrusion during the production process. The high-viscosity liquid extrusion devices currently used on the market usually have the material guide tube located below the device and use gravity to assist the fluid flow out to achieve a labor-saving effect; however, in actual use, if the implementer fails to close the valve in time after extrusion is completed, the fluid is easily affected by gravity and flows out, causing errors and losses, which is not conducive to application in areas where strict control of usage is required. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to design a high-viscosity liquid extrusion device, in which a material guide tube is set at the top of the container body, and the fluid is driven by a piston and a pressure cylinder to overcome gravity and extrude the fluid to prevent the fluid from flowing out due to the influence of gravity and causing errors and losses.

[0005] Furthermore, the discharge end of the material guiding pipe is arranged above the barrel cover.

[0006] Furthermore, a first oil seal is provided on the edge of the pressure plate.

[0007] Furthermore, the first through hole is provided with a second oil seal.

[0008] Furthermore, the pressure plate is located below the high-viscosity liquid.

[0009] Furthermore, the pressure plate is located above the high-viscosity liquid.

[0010] Furthermore, the feed end of the material guide pipe extends to the bottom of the charging barrel.

[0011] Furthermore, the pressure plate is provided with a second through hole for the material guide tube to pass through.

[0012] Furthermore, a third oil seal is provided on the second through hole.

[0013] After adopting the above technical solution, the beneficial effect of the utility model is: the extrusion device of the utility model can effectively prevent the valve from closing in time and causing errors or losses due to the outflow of fluid under the influence of gravity by setting the discharge end of the guide tube at the top of the container body.

[0018] The technical solution of the present invention is further described below by way of embodiments:

[0019] [Example 1]

[0020] The utility model provides a high viscosity liquid extrusion device, combined with Figures 1-2 As shown, the high-viscosity liquid extrusion device includes a container body 1, an extrusion assembly 3, and a bracket 2 for placing the container body 1 and the extrusion assembly 3. The container body 1 includes a guide tube 101, a valve 100, a charging barrel 103, and a barrel cover 102. The barrel cover 102 covers the upper port of the charging barrel 103. The valve 100 is provided on the guide tube 101 for controlling the opening and closing of the guide tube 101. The feed end of the guide tube 101 is connected to the interior of the charging barrel 103.

[0021] The extrusion assembly 3 includes a pressure plate 300 and a pressure cylinder 303. The pressure plate 300 is fixedly connected to the piston rod 301 of the pressure cylinder 303 and is used to drive the piston to squeeze the high-viscosity liquid 4. The pressure cylinder 303 is located below the charging barrel 103, and the pressure plate 300 is located inside the charging barrel 103. The bottom outer diameter of the pressure plate 300 matches the inner diameter of the charging barrel 103. The bottom of the charging barrel 103 is provided with a first through hole for the piston rod 301 to pass through.

[0022] The pressure cylinder 303 can be a pneumatic cylinder or an oil cylinder. In this embodiment, the feed end of the material guide tube 101 passes through the barrel cover 102 and is connected to the loading barrel 103. A first oil seal 302 is provided on the edge of the pressure plate 300. When the high-viscosity liquid 4 is contained, the pressure plate 300 is positioned below the high-viscosity liquid 4. The pressure cylinder 303 drives the pressure plate 300 upward to squeeze the liquid out. When the pressure cylinder 303 stops moving, the high-viscosity liquid 4 will not leak out due to gravity.

[0023] Specifically, a second oil seal 104 is provided on the first through hole to prevent material from leaking out.

[0024] The specific working conditions of the high viscosity liquid extrusion device are as follows:

[0025] Open the valve 100 to allow the liquid to flow out, start the pressure cylinder 303, lift the piston upward, squeeze the liquid upward from the bottom of the charging barrel 103, and then flow out from the guide pipe 101; when the charging is stopped, close the pressure cylinder 303, stop the piston from working, and close the valve 100 to prevent the liquid from overflowing.

[0026] [Example 2]

[0027] like Figure 3 As shown, the container body 1, extrusion assembly 3, and bracket 2 of this embodiment are the same as those of Example 1 and will not be described in detail here. Unlike Example 1, in this embodiment, the feed end of the material guide tube 101 of the high-viscosity liquid extrusion device extends to the bottom of the charging barrel 103. The pressure plate 300 is located above the high-viscosity liquid 4 and is provided with a second through hole for the material guide tube 101 to pass through. The second through hole is provided with a third oil seal to prevent leakage of the high-viscosity liquid 4.

[0028] In actual use, the pressure cylinder 303 is started, and the piston squeezes the high-viscosity liquid 4 downward. The high-viscosity liquid 4 flows out through the guide tube 101 under the action of pressure. At this time, the movement direction of the pressure plate 300 is consistent with the direction of gravity, making glue squeezing more labor-saving.
