Description

Technical Field

[0001] The invention relates to the technical field of non-metal composite material molding and fiber fabric prepreg preparation, and in particular to a glue dispensing and glue filling circulation system. Background Art

[0002] In the production process of fiber fabric prepreg used in non-metallic composite materials, the fiber fabric needs to pass through a glue tank filled with resin glue to make the resin glue soak the fiber fabric and initially form the fiber fabric prepreg. In this process, the glue in the glue tank will continue to decrease as the length of the fiber fabric passing through increases. At the same time, since the glue tanks used in this process are mostly open / semi-open, the solvent in the glue will evaporate as the production time increases, causing the glue concentration to gradually increase. Therefore, how to achieve real-time monitoring of the glue concentration and real-time replenishment of the glue has become one of the important issues in the preparation process of fiber fabric prepreg.

[0003] At present, there are no mature implementation cases and reference solutions to solve this problem in actual engineering applications. Whether it is to replenish glue or detect the glue concentration, the machine must be stopped, and real-time monitoring and replenishment cannot be achieved. Therefore, it is urgently needed to design and manufacture a device for the fiber fabric prepreg preparation process that can monitor the glue concentration in the glue tank and replenish the glue in the glue tank without stopping the machine. Summary of the invention

[0004] In view of this, in order to realize the method of maintaining the concentration and weight of the resin glue solution in the glue tank during the current fiber fabric prepreg preparation process, the present invention proposes a glue mixing and filling circulation system.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A glue dispensing and glue replenishing circulation system comprises a glue tank and a glue dispensing barrel, wherein the lower end of the glue dispensing barrel is connected to the glue tank through a glue outlet pipe, and the glue tank and the upper end of the glue dispensing barrel are connected to the glue inlet pipe through a liquid pump.

[0007] As a further improvement of the above technical solution:

[0008] The glue dispensing barrel is arranged on the glue dispensing rack, the lower end of the glue dispensing rack is in an overhead state, and the liquid extraction pump is arranged on the glue dispensing rack.

[0009] Preferably, the lower surface of the glue dispensing barrel is higher than the upper surface of the glue groove.

[0010] Preferably, a glue dispensing scale is provided at the lower end of the glue dispensing rack.

[0011] Preferably, the glue dispensing rack is placed on a fixing rack.

[0012] Preferably, a pedal frame is provided at the front end of the fixing frame.

[0013] Preferably, the bottom of the glue dispensing barrel is provided with an opening and a valve.

[0014] Preferably, a densitometer is provided at the upper end of the glue dispensing barrel.

[0015] Preferably, an agitator is provided at the upper end of the glue preparation barrel.

[0016] Preferably, a barrel cover is provided at the upper end of the supporting barrel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) The present invention improves the traditional method of replenishing and monitoring glue in the preparation of fiber fabric prepreg, and realizes a glue preparation and glue replenishment circulation system that integrates monitoring and glue replenishment functions. An external glue preparation and glue replenishment device is used to replace the traditional manual glue preparation and glue replenishment method during machine shutdown. A liquid pump is used to connect the glue tank and the external glue preparation and glue replenishment device to form a glue circulation system, so as to realize real-time monitoring of glue concentration.

[0019] 2) The glue mixing and replenishing circulation system solves the problem of stopping the fiber fabric prepreg preparation process for glue replenishment and inspection.

[0020] 3) The main body of the present invention adopts a stainless steel structure and a PU steel wire tube is used to transport the adhesive liquid, both of which have good solvent resistance.

[0021] 4) The glue replenishing circulation system improves the glue replenishing method from the original cumbersome multi-step work of shutdown, inspection, glue preparation, glue replenishing, startup, etc. to directly monitoring the glue concentration through a density meter, and directly replenishing the solvent and original resin glue to maintain the glue concentration and weight.

[0022] 5) The invention uses standard PU steel wire tube, ordinary stainless steel cylinder and finished liquid pump, making it more modular, standardized and low-cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Therefore, as attached Figure 1 As shown, in the technical solution, a corresponding glue circulation system is arranged next to the glue tank 10, which will not affect the continuity of the infection process. It is mainly composed of the following parts:

[0036] Fixed frame 1, glue dispensing scale 2, glue dispensing frame 3, glue outlet hose 4, glue dispensing barrel 5, density meter 6, stirrer 7, liquid pump 8, glue inlet hose 9, glue tank 10.

[0037] The fixing frame 1 is used for fixing the glue dispensing scale 2 and the agitator 7 , and the pedal frame 11 is provided to facilitate the operator to add the glue liquid and the solvent into the glue dispensing barrel 5 .

[0038] The glue mixing scale 2 uses an ordinary electronic balance to weigh the glue solution and the solvent.

[0039] The glue dispensing rack 3 is placed on the glue dispensing scale 2, and is used to fix and lift the glue dispensing barrel 5 so that the glue dispensing barrel 5 is higher than the glue tank 10, and at the same time forms an overhead space, which is convenient for operating the bottom valve 51 and replacing the glue outlet pipe 4; in addition, the glue dispensing rack 3 is used to fix the liquid extraction pump 8.

[0040] The rubber outlet pipe 4 is used to introduce the glue liquid in the glue barrel 5 into the glue tank 10. Ordinary PU steel wire pipe is used to ensure strength and solvent resistance. At the same time, it is low in price and easy to replace.

[0041] As attached Figure 2 As shown, the glue barrel 5 has a hole at the bottom and is welded with a valve 51, which is connected to the glue outlet pipe 4 through the valve 51. The speed of the glue liquid flowing into the glue tank 10 can be controlled by the valve 51 to ensure the liquid level of the glue liquid.

[0042] The glue preparation barrel 5 is provided with a barrel cover (not shown in the figure), and the barrel cover has three holes, through which a density meter 6, a stirrer 7, and a glue inlet pipe 9 are passed respectively, and can be used in combination for glue preparation.

[0043] The density meter 6 uses an ordinary glass liquid density meter 6, which can be quickly replaced according to the target glue liquid density, and is used to observe and detect the density of the prepared glue liquid, while realizing real-time monitoring of the glue liquid density.

[0044] The agitator 7 can be a pneumatic or electric agitator 7 according to the situation, and is used to stir the glue solution during the preparation of the glue solution and the circulating glue replenishment, so that the glue solution and the solvent are evenly mixed.

[0045] As attached Figure 3 As shown, two ends of the liquid extraction pump 8 are respectively connected to two glue inlet pipes 9 to extract the glue in the glue tank 10 into the glue preparation barrel 5 to achieve glue circulation and ensure that the glue concentration in the glue tank 10 is consistent with that in the glue preparation barrel 5. A pneumatic or electric liquid extraction pump 8 can be used according to the situation.

[0046] The glue inlet pipes 9 are two common PU steel wire pipes, one connecting the glue tank 10 and the liquid extraction pump 8, and the other connecting the glue dispensing barrel 5 and the liquid extraction pump 8.
