Description

Technical Field

[0002] Double-sided tape, as an important connecting and fixing material, is widely used in many fields such as electronic products, automobile manufacturing, and packaging materials. In the production process of double-sided tape, the surface layer and the adhesive layer of the tape need to be pressed together. In the existing technology, some pressing equipment often adopts a single pressing method, such as flat pressing or roller pressing. This method is difficult to ensure that the double-sided tape is subjected to uniform force during the pressing process. Especially when processing wider tapes, it is easy to over-press the middle part and under-press the two sides, resulting in wrinkles or bubbles inside the tape, reducing the quality of the tape.

[0024] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments.

[0025] The double-sided tape pressing assembly has a main board 1, a support base 2, a driving shaft 3, a driven shaft 4, inclined plates 5, an extrusion bar 6 and a transmission roller 7;

[0026] As shown Figures 1 to 4 in the figure, the main board 1 is used for bearing and supporting. A support base 2 is fixedly installed on one side of the main board 1. A pair of driving shafts 3 and a pair of driven shafts 4 are symmetrically and rotatably connected between the inside of the support base 2 and the main board 1. Two groups of inclined plates 5 are rotatably connected to the outer sides of the driving shaft 3 and the corresponding driven shaft 4, and the two groups of inclined plates 5 are symmetrically arranged. Each group of inclined plates 5 has two, and the two inclined plates 5 are parallel to each other. A plurality of extrusion strips 6 are equidistantly arranged between each group of inclined plates 5, and the extrusion strips 6 between each group of inclined plates 5 are strung together by a soft rope to form an endless belt. The extrusion strips 6 are fixedly connected to the soft rope. Transmission rollers 7 are fixedly connected to the outer sides of the driving shaft 3 and the driven shaft 4 between the inclined plates 5. Grooves are equidistantly formed on the outer sides of the transmission rollers 7, and the grooves are matched with the extrusion strips 6. The transmission rollers 7 between the driving shaft 3 and the corresponding driven shaft 4 are connected by an endless belt for transmission.

[0027] The double-sided tape is composed of two surface layers and one adhesive layer. During the pressing process, the two surface layers and the middle adhesive layer are simultaneously and smoothly conveyed to the area between the two groups of driving shafts 3 and driven shafts 4. The two surface layers are on the outside, and the adhesive layer is located between the two surface layers. The two driving shafts 3 rotate synchronously and relatively. The rotation of the driving shaft 3 drives the endless belt composed of the extrusion strips 6 and the soft rope connected thereto to move through the transmission roller 7. Since the endless belt is matched with the grooves of the transmission roller 7, the endless belt can move smoothly along the surface of the transmission roller 7. The extrusion strips 6 move along the V-shaped space formed between the two groups of inclined plates 5 to form two endless belts. These two endless belts move relatively in the V-shaped space, simulating the transmission mode of a chain, but the path is more special, in a V shape. When the double-sided tape passes through, it is first pressed at the middle position of the V shape by the endless belt, and then as the endless belt moves towards both sides of the V shape, the tape is gradually clamped until the edge. This pressing method ensures that the tape is evenly stressed during the pressing process, gradually increasing from the middle to both sides, effectively avoiding the problem of wrinkles or bubbles inside the relatively wide tape during pressing. After the above pressing process, the two surface layers and the middle adhesive layer of the double-sided tape are firmly pressed together to form a stable structure.

[0028] As shown Figures 1 to 4 in the figure, a gear 8 is fixedly connected to the outer side of one end of the driving shaft 3. The gears 8 are meshed with each other, so that the two driving shafts 3 can achieve synchronous and relative rotation through the meshing of the gears 8.

[0029] As shown Figures 1 to 4 in the figure, both ends of the extrusion strip 6 are spherical. The spherical design enables the extrusion strip 6 to better adapt to the shape of the inclined plate 5 during the pressing process and travel along between the inclined plates 5.

[0030] As shown Figures 1 to 4As shown, the length of the extrusion strip 6 is the same as the spacing between each group of inclined plates 5, ensuring that the extrusion strip 6 can completely cover and press the effective width area of the tape. When the extrusion strip 6 moves along the inclined plate 5, they can closely fit on the tape to achieve a uniform pressing effect.

[0031] As Figures 1 to 4 shown, the main board 1 is fixedly connected with side plates 10 through struts 9. Guide rollers 11 are rotatably connected at equal distances between the side plates 10 and the main board 1. The equally spaced guide rollers 11 can also ensure that the tape remains stable and non-twisted during transportation, providing a good foundation for the subsequent pressing action.

[0032] As Figures 1 to 4 shown, retaining plates 12 are symmetrically and fixedly connected to the outside of the guide rollers 11. The setting of the retaining plates 12 further enhances the guiding effect of the guide rollers 11, preventing the tape from shifting or falling off during transportation.

[0033] As Figures 1 to 4 shown, the two groups of inclined plates 5 are arranged in a V shape, enabling the extrusion strip 6 to move along the V-shaped space to form two relatively moving annular belts.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
