[0022] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , 2 , 3, and 4 are specific embodiments of the curtain die guide mechanism of the utility model. The embodiment comprises a main support 1, a material receiving trough 2 is arranged on the upper part of the main support 1, a guide assembly is arranged on one side of the main support 1, the guide assembly comprises a guide frame 3 and a guide trough 4 vertically penetrating the inner side of the guide frame 3, the main support 1 can be horizontally movably arranged on the side of the curtain die, the material receiving trough 2 is used to receive and recover the external fluid, and the guide trough 4 is used to guide and trim the edge of the fluid.

[0024] When the utility model is in use, two groups of guide mechanisms are installed on both sides of the curtain die head. The two groups of guide mechanisms are arranged in a mirror image, and then the edges of the two sides of the curtain die head are trimmed. According to the width requirement of this trimming, the horizontal position of the main bracket 1 is adjusted to the guide groove 4 corresponding to the trimming position. The curtain die head is relative to the outer side of the guide groove 4, and the falling fluid can be received and collected by the outer receiving groove 2, which can realize the recycling of the fluid and greatly save costs compared with the prior art. The fluid of the curtain die head falls to the product in an orderly manner along the wide direction, and the edge of the fluid is guided by the guide groove 4. The fluid at the edge flows downward along the guide groove 4 and reaches the edge of the product, which can ensure the neatness and order of the trimming and ensure the quality of the product. The horizontal adjustment of the guide mechanism also gives the mechanism a large adjustment range when trimming the edges, with a wide range of production and use, easy use, and low difficulty in operation.

[0025] As an improved specific implementation method, a blowing air inlet 41 is provided at the lower portion of the guide frame 3, and a blowing air outlet 42 is provided at the upper portion of the guide frame 3. The outlet of the blowing air outlet 42 corresponds to the upper end of the guide groove 4. The blowing air inlet 41 and the blowing air outlet 42 are connected and air is blown to the blowing air inlet 41 through an external air source.

[0026] like Figure 1 , 2 As shown in FIG. 3 , when in use, an external air source is connected to the blowing edge air inlet 41, and air can be blown out from the blowing edge air outlet 42 by blowing, thereby guiding the fluid at the upper end of the guide groove 4 to enter the guide groove 4, and flow evenly downward along the guide groove 4, so as to achieve a uniform edge trimming effect.

[0027] As an improved specific implementation method, the guide frame 3 is adjustablely connected to the main bracket 1, and the guide frame 3 is locked on the main bracket 1 through the upper and lower adjustment fasteners 31 and the vertically arranged waist-shaped holes, and the upper and lower positions of the guide frame 3 relative to the main bracket 1 are adjusted when the upper and lower adjustment fasteners 31 are loosened.

[0028] like Figure 2 , 3 As shown, the up and down adjusting fasteners 31 can preferably be standardized fasteners such as screws and bolts. Corresponding screw holes are set on the main bracket 1 for adaptive installation. When the up and down adjusting fasteners 31 are tightened, the position of the guide frame 3 is locked. When it is loose, it can rely on the vertically set waist-shaped holes to move relatively up and down along the up and down adjusting fasteners 31, and then adjust the up and down position of the guide frame 3 relative to the main bracket 1, so as to achieve a more precise up and down adjustment of the upper and lower end positions of the guide groove 4 to ensure the required edge finishing effect.

[0029] As an improved specific implementation method, the guide frame 3 is adjustablely connected to the main bracket 1, and the guide frame 3 is locked on the main bracket 1 through the front and rear adjustment fasteners 32 and the horizontally arranged waist-shaped holes, and the front and rear position of the guide frame 3 relative to the main bracket 1 is adjusted when the front and rear adjustment fasteners 32 are loose.

[0030] like Figure 2 , 3 As shown, the front and rear adjustment fasteners 32 can preferably be standardized fasteners such as screws and bolts. Corresponding screw holes are set on the main bracket 1 for adaptive installation. When the front and rear adjustment fasteners 32 are tightened, the position of the guide frame 3 is locked. When loosened, the front and rear horizontal waist-shaped holes can be relied on to move relative to the front and rear adjustment fasteners 32 to adjust the front and rear position of the guide frame 3 relative to the main bracket 1, thereby achieving a more precise front and rear adjustment of the upper and lower end positions of the guide groove 4 to ensure the required edge finishing effect.

[0031] As an improved specific implementation manner, the rear portion of the main support 1 is horizontally movable on the side of the curtain die head through a guide rail slider structure 5 .

[0032] like Figure 1 , 4 As shown, the guide rail slider structure 5 can stably set the main bracket 1 and the curtain die head to be horizontally movable, with high activity stability and high position adjustment accuracy. After the adjustment is completed, the position can be locked through the existing locking structure.

[0033] As an improved specific implementation manner, a discharge port 21 is provided on the main support 1 corresponding to the bottom of the receiving trough 2 .

[0034] like Figure 1 , 2 As shown in Figures 4, the discharge port 21 is provided to facilitate the convenient collection and recycling of the fluid after being connected to an external pipeline; in normal times, the discharge port 21 can be closed by providing a cover, or a pipeline can be installed and a valve can be used to control the opening and closing, so as to be used flexibly.

[0035] As an improved specific implementation manner, a diversion chute 22 is further extended from the outer side of the material receiving chute 2.

[0036] like Figure 1 , 2 As shown in FIG. 4 , after the fluid on the outside falls into the diversion chute 22 , it can flow to the receiving trough 2 on the inside, thereby achieving better centralized collection.

[0037] As an improved specific implementation manner, a drainage ramp 33 is further provided between the upper end of the guide groove 4 and the material receiving groove 2 .

[0038] like Figure 1 , 2As shown in Figures 3 and 4, the fluid that falls into the guide groove 4, in addition to the fluid that can enter the guide groove 4, the excess fluid can fall along the drainage ramp 33 to the receiving trough 2 for collection, thereby ensuring that the edge is collected in an orderly manner, and is more conducive to the recycling of the fluid and avoiding fluid overflow and contamination of the surrounding area.

[0039] As an improved specific implementation manner, a moving handle 11 is also provided on the main support 1 .

[0040] like Figure 1 , 2 As shown, by setting the movable handle 11, it is convenient for the operator to apply force on the movable handle 11 to adjust the horizontal position of the main bracket 1.

[0041] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
