DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Figure 1-Figure 5 An embodiment of the utility model is a polyurethane structural adhesive packaging device, comprising a mounting seat 1 and a conducting wheel 2 arranged at the lower end of the mounting seat 1 for conveying a sealing film, a discharging head 3 for holding the polyurethane structural adhesive is installed on the mounting seat 1, an edge sealing component 4 for edge sealing is arranged on the mounting seat 1 below the discharging head 3, and a sealing member 5 is arranged on the mounting seat 1 away from the discharging head 3.

[0024] In this specific embodiment, the technical problem addressed is: to solve the problem of incomplete filling of internal raw materials after the structural adhesive is packaged. The utility model uses a support frame 51 installed on the mounting seat 1 to support the sealing member 5. The basic lifting member 52 and the sliding rod 53 installed on the support frame 51 provide a force basis for the movement of the lining block. Based on the complementary arrangement of the shapes of the protrusion 57 and the extension ring 56, after the extension ring 56 descends in height and contacts the protrusion 57, the structural adhesive in the sealing film is squeezed, thereby forcing the air layer in the sealing film to be discharged outward and then squeezed, thereby enhancing the fullness of the raw material in the pressed film.

[0025] The sealing member 5 includes a support frame 51 installed on the mounting seat 1, and a basic lifting member 52 and a sliding rod 53 installed on the basic lifting member 52 are clamped on the support frame 51. The basic lifting member 52 includes a screw rod installed on the support frame 51, and the screw rod is installed symmetrically with respect to the mounting seat 1. Lifting sleeves are screwed on the two screw rods, and a straight rod is clamped between the two lifting sleeves. The sliding rod 53 passes through the straight rod from left to right, and the sliding rod 53 is rotatably connected to the straight rod, and a driving source for driving the sliding rod 53 to assemble is connected to the sliding rod 53. The lower end of the screw rod is connected to a driving motor installed on the support frame 51. The driving motor is driven to rotate by the controller, and under the rotation of the driving motor, the lifting sleeve is adjusted in height and lifts the height of the straight rod, thereby synchronously driving the sliding rod 53 to slide against each other. The rod 53 is sleeved with symmetrically screwed bushings 54 that move in opposite directions. The threads of the two bushings 54 are opened in different directions. A connecting block 55 is provided at one end of the bushing 54 away from the sliding rod 53. Extension rings 56 that fit each other are installed on the relative structure of the two connecting blocks 55. The extension ring 56 is sleeved on the outside of the sealing film wrapped with the polyurethane structural adhesive. A protrusion 57 with a complementary shape to the extension ring 56 is provided on the mounting seat 1 at the matching position with the extension ring 56. First, the height of the connecting ring is lowered by using the basic lifting member 52 and connected with the protrusion 57, thereby pushing the structural adhesive in the extrusion film to the left and right ends, and then using the driving source connected to the sliding rod 53 to drive the two connecting rings to the opposite ends, thereby forming a gap between the two connecting rings, which is convenient for external mechanical intervention to perform tying and cutting operations.

[0026] The edge sealing assembly 4 includes a support tube 41 which is arranged on the mounting seat 1 and is placed at the lower end of the discharge head 3. The support tube 41 is provided with a material port for the discharge head 3 to fill downward. A folding rod 421 for overlapping the film edge at the sealing opening of the film is installed at the right end of the support tube 41. The folding rod 421 overlaps the film edge at the sealing opening of the film before the film pressing member 44 acts on it. The film pressing member 44 uses the existing technology of the connecting section, such as Figure 3 As shown in the figure, a hot air knife is installed in the cylindrical film pressing member 44, and the film that has completed the overlap of the film edges is sealed by heating the hot air knife, thereby ensuring the overlapping state during film pressing, thereby enhancing the film pressing effect and avoiding the reduction of the film pressing sealing effect due to the misalignment of the film edges. An auxiliary delivery sleeve 43 is integrally formed with the folding rod 421, and a film sealing film wrapped with polyurethane structural adhesive is sleeved on the transmission track to the right end. A film pressing member 44 for edge sealing is installed between the auxiliary delivery sleeve 43 and the folding edge, and a plurality of transmission wheels 45 with a surrounding diameter equal to the film wrapping diameter are installed on the inner annular surface of the auxiliary delivery sleeve 43.

[0027] The stacking rod 421 includes a straight rod installed on the mounting seat 1 and stacking pieces 422 installed on the opposite end surfaces of the two straight rods and extending toward the polyurethane structural adhesive transmission track. The two stacking pieces 422 are staggered up and down and their action ranges overlap.

[0028] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0029] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
