It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0034] Example 1

[0035] This utility model discloses an auxiliary machine for forming encapsulating films, such as... Figure 1 , Figure 2 As shown, the machine includes a frame 1, inside which are arranged multiple functional rollers 2 and a mesh belt 3 that directly contacts the multiple functional rollers 2. The multiple functional rollers 2 work together to drive the mesh belt 3. The adhesive film raw material is coated onto the surface of the mesh belt 3 from the extruder at the feed end of the frame 1.

[0036] The mesh belt 3 can be made of high-strength nylon or steel wire mesh belt. Both of these materials have good heat resistance and tensile strength, and can withstand high working temperatures and large tensions. In this embodiment, nylon mesh belt 3 is used, and the width of the mesh belt 3 can be adjusted according to actual needs.

[0037] Reference Figure 2The distribution of multiple functional rollers 2 within the frame 1 causes the mesh belt 3 to spatially form a closed loop structure consisting of an upper receiving surface 31, a first vertical side surface 32, an upper roller-passing surface 33, a second vertical side surface 34, a lower roller-passing surface 35, and a third vertical side surface 36. The mesh belt 3 circulates and is driven by the cooperation of the multiple functional rollers 2. The first vertical side surface 32 is inclined relative to the upper receiving surface 31, and the angle formed between the two surfaces is 90°. In other embodiments, the inclination angle of the first vertical side surface 32 can be varied, and the angle formed between it and the upper receiving surface 31 can be selected within the range of 75-120°.

[0038] Reference Figure 2 , Figure 3 The multiple functional rollers 2 include a flattening roller 21, which is movably disposed below the upper receiving surface 31 and in direct contact with the first vertical side 32 to adjust the tension applied to the first vertical side 32. The frame 1 has guide rail holes 4 on both sides of the conveyor path of the mesh belt 3, which allow the end of the flattening roller 21 to move horizontally. When the film thickness is large, the flattening roller 21 can be adjusted along the guide rail holes 4 towards the first vertical side 32 to provide greater stress to the film. This design enables the flattening roller 21 to generate sufficient tension on the mesh belt 3 to adapt to different film thicknesses, improving the practicality and applicability of the auxiliary machine.

[0039] Reference Figure 2 , Figure 3 One end of the flattening roller 21 is connected to a slider 9. The flattening roller 21 passes through the center of the slider, and a bearing is provided at the connection between the flattening roller 21 and the slider 9. The bottom of the slider 9 is slidably connected to the lower surface of the guide rail hole 4. A telescopic motor 10 is provided on one side of the slider 9, and the output shaft of the telescopic motor 10 is fixedly connected to the slider 9. By driving the slider 9, the flattening roller 21 can be controlled to move within the guide rail hole 4. A gear 11 is embedded at the end of the flattening roller 21, and a rack structure is provided on the upper surface of the guide rail hole 4. The gear 11 and the rack structure are meshed with each other. When the telescopic motor 10 drives the flattening roller 21 to move horizontally along the guide rail hole 4, the gear 11 moves on the rack structure, thereby realizing the rotation of the flattening roller 21. It should be noted that in this embodiment, the length of the guide rail hole 4 is 40mm, so that the maximum length of the flattening roller 21 moving horizontally can be 40mm. However, in other embodiments, the length of the guide rail hole 4 can be selected from 40-60mm.

[0040] Reference Figure 2The plurality of functional rollers 2 include two heating rollers 22, one of which is arranged below the upper receiving surface 31 and directly contacts the upper receiving surface 31 at the junction of the upper receiving surface 31 and the third vertical side surface 36 and directly contacts the upper receiving surface 31 and the third vertical side surface 36. The other heating roller 22 is arranged below the upper receiving surface 31 and directly contacts the third vertical side surface 36.

[0041] The heating roller 22 is mainly used for preheating the film raw material, so that it is easier to expand.

[0042] Referring to Figure 2 The plurality of functional rollers 2 include a set of pressing rollers 7 arranged on both sides of the first vertical side surface 32, which includes a first pressing roller 71 and a second pressing roller 72. The film raw material after heating passes between the first pressing roller 71 and the second pressing roller 72 along the mesh belt 3. The uniform pressure of the set of pressing rollers 7 can ensure the uniform thickness of the film and guarantee the product quality.

[0043] Referring to Figure 2 The plurality of functional rollers 2 further include a cooling roller 23 arranged at the junction of the upper passing roller surface 33 and the second vertical side surface 34 and directly contacting the upper passing roller surface 33 and the second vertical side surface 34. The film raw material after being flattened by the set of pressing rollers 7 is cooled and shaped after passing through the cooling roller 23 to prevent it from shrinking and deforming again, and then the film enters the external winding mechanism for winding. The surface of the cooling roller 23 can be made of copper material, because copper has good heat conduction performance and can quickly take away heat.

[0044] The functional rollers 2 further include a driving roller 8 driven by a rotating motor to drive the mesh belt 3 to transmit the film.

[0045] Referring to Figure 2 The frame 1 is provided with two static electricity elimination devices, i.e. high-voltage generators, which are a first static electricity elimination device 5 and a second static electricity elimination device 6. The first static electricity elimination device 5 is arranged above the upper receiving surface 31 near one end of the first vertical side surface 32 and does not contact the upper receiving surface 31 to eliminate static electricity on the surface of the film and reduce electrostatic adsorption between the film and the mesh belt 3, so as to facilitate the subsequent transmission of the film out of the mesh belt 3.

[0046] The second static electricity elimination device 6 is arranged beside the middle part of the second vertical side surface 34 and does not contact the second vertical side surface 34 to eliminate static electricity on the surface of the mesh belt 3 and reduce the problem of dust adhesion, thereby guaranteeing the quality of the film.

[0047] Working principle: the utility model discloses a kind of packaging adhesive film forming auxiliary machine, adhesive film raw materials are extruded from the extruder of rack 1 feeding end and are coated to the surface of mesh belt 3, in turn pass through warming roller 22, first static electricity elimination device 5, flatten roller 21, press roller group 7, cooling roller 23 after shaping as adhesive film, then transmit the surface of mesh belt 3 and enter the winding device of outside and wind up;

[0048] The tension applied by flatten roller 21 makes the adhesive film raw materials not to be separated from the surface of mesh belt 3 when entering the first vertical side surface 32 from the upper receiving surface 31, so as to reduce wrinkles, and the adhesive film can be expanded by the characteristics of flatten roller 21, so as to improve flatness and reduce the occurrence of wrinkles.
