Description

Technical Field

[0001] This utility model relates to the field of forming roller technology, and in particular to an anti-sticking composite forming roller. Background Technology

[0002] Currently, the laminating rollers in pre-coated film production equipment are generally made of carbon steel. However, during the pre-coated film production process, the EVA adhesive sprayed from the die head tends to adhere to the laminating roller during film lamination, especially when the width of the EVA spray exceeds the width of the film. The unlaminated areas on both sides of the film are more prone to sticking to the roller. This can cause the film to break, thus affecting the quality of the final product.

[0003] To address the aforementioned issues, patent document CN213590940U discloses an anti-stick composite molding roller, comprising a composite molding roller body. The side and end surfaces of the composite molding roller body are coated with an anti-stick layer. The anti-stick layer is formed by spraying, curing, and drying a high-temperature resistant two-component anti-stick coating, resulting in a smooth surface on the anti-stick composite molding roller.

[0004] The above-mentioned technical solution achieves the anti-sticking effect by spraying an anti-sticking layer on the outside of the forming roller. However, during the pre-coated film production process, the composite forming roller is often exposed to high temperatures, especially when in contact with hot melt adhesives (such as EVA adhesive). Prolonged exposure to high temperatures may damage the molecular structure of the anti-sticking layer, leading to its detachment. During production, the surface of the composite forming roller experiences contact and friction with the film, especially when the film width is unsuitable or tension is uneven. Strong friction and impact may reduce the adhesion between the anti-sticking layer and the roller, ultimately causing it to detach. In the above design, once the anti-sticking layer detaches, the entire forming roller needs to be replaced, directly impacting efficiency and material costs. Therefore, we propose an anti-sticking composite forming roller to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide an anti-sticking composite molding roller to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-stick composite molding roller includes: a molding roller body, a protective cover detachably installed on the outer side of the molding roller body, an anti-stick coating being sprayed on the outer side of the protective cover, and quick-release mechanisms provided at both ends of the molding roller body.

[0008] The quick-release mechanism includes a threaded sleeve, a sliding ring, and two retaining plates. The sliding ring is slidably sleeved on the outside of the threaded sleeve, and the retaining plates are slidably connected to the inside of the forming roller body. The inside of the protective cover is provided with a retaining groove. One end of the retaining plate is movably engaged in the corresponding retaining groove, and the other end of the retaining plate is fixedly connected to a diagonal rod. Two diagonal holes are provided on one side of the sliding ring, and the diagonal rod is slidably connected in the corresponding diagonal holes.

[0009] The forming roller body has grooves at both ends, and a threaded rod is fixedly connected to the side wall of the groove. The other end of the threaded rod is fixedly connected to an installation shaft, and the threaded sleeve is threaded onto the outside of the threaded rod.

[0010] Preferably, the anti-stick layer is formed by spraying, curing, and drying a high-temperature resistant silicone resin coating.

[0011] Preferably, a connecting rod is fixedly connected to each of the two threaded sleeves on the side away from each other, and an annular plate is fixedly connected to the other end of the connecting rod. A fastening bolt is threadedly connected to the outer side of the annular plate. Positioning grooves are provided at the top and bottom of the mounting shaft, and one end of the fastening bolt is movably inserted into the corresponding positioning groove.

[0012] Preferably, a compression spring is fixedly connected to each of the two sliding rings on the side away from each other, a fixing ring is fixedly connected to the groove, and the other end of the compression spring is fixedly connected to the corresponding fixing ring.

[0013] Preferably, guide strips are fixedly connected to the inner walls of both the front and rear sides of the groove, and the sliding ring is slidably sleeved on the outer side of the corresponding guide strip.

[0014] Preferably, vertical holes are provided on the top and bottom inner walls of the groove, and the card plate is slidably connected in the corresponding vertical holes.

[0015] Preferably, keyways are provided on both the front and rear sides of the mounting shaft.

[0016] Preferably, two limiting rings are fixed on the outer side of the threaded sleeve, and the two limiting rings are respectively movably abutting against both sides of the sliding ring.

[0017] In this invention, an anti-stick composite molding roller is constructed by spraying a silicone resin coating onto the outside of a protective cover and then drying and curing it. The silicone resin coating possesses excellent high-temperature resistance, typically withstanding temperatures ranging from 300°C to 600°C, which is crucial for equipment requiring high-temperature operation, such as pre-coated film production. The anti-stick layer operates stably in high-temperature environments and is not easily degraded or peeled off due to temperature changes. The surface of the silicone resin coating forms a smooth layer with low surface energy, effectively reducing the adhesion of EVA adhesive, other adhesives, or materials. This prevents materials splashed during production from easily adhering to the protective cover surface, avoiding the accumulation of adhering substances and reducing problems such as roller sticking and cleaning difficulties.

[0018] In this utility model, an anti-stick composite molding roller is used to fix the protective cover by engaging the locking plate and the locking groove. Unscrewing the fastening bolt releases the fixation on the annular plate. Then, rotating the annular plate causes the threaded sleeve to rotate synchronously via the connecting rod. The threaded sleeve rotates horizontally through its threaded engagement with the threaded rod, and the sliding ring moves synchronously horizontally through the engagement of the limiting ring and the sliding ring. The sliding ring, through its oblique hole and oblique rod, causes two locking plates on the same side to move closer together, allowing the locking plates to disengage from the locking groove and release the fixation on the protective cover. This allows the protective cover to be replaced separately when the anti-stick coating is damaged, while the molding roller body can continue to be used. The new protective cover is fitted onto the outside of the molding roller and installed in place. Then, the annular plate is rotated in the opposite direction, causing the locking plate to engage in the locking groove, thus fixing the protective cover. Finally, the fastening bolt is rotated in the opposite direction to insert it into the positioning groove, locking the annular plate, thereby achieving the installation of the protective cover.

[0019] This utility model has a reasonable structural design. By installing a protective cover on the outside of the forming roller and spraying silicone resin coating on the outside of the protective cover and then drying and curing it, the accumulation of adhering substances is avoided and the high temperature resistance is improved. The quick-release mechanism facilitates the individual and quick replacement of the protective cover, reducing the cost of replacement parts. Attached Figure Description

The other end of the threaded rod 101 is fixedly connected to the mounting shaft 102, and the threaded sleeve 7 is threadedly sleeved on the outside of the threaded rod 101.

[0030] In this embodiment, the anti-stick layer is formed by spraying, curing and drying a high-temperature resistant silicone resin coating.

[0031] In this embodiment, a connecting rod is fixedly connected to the side of each of the two threaded sleeves 7 that is far apart from each other.

Positioning grooves are provided at the top and bottom of the mounting shaft 102. One end of the fastening bolt 10 is movably inserted into the corresponding positioning groove.

[0032] In this embodiment, a compression spring 8 is fixedly connected to each side of the two sliding rings 6 that are far apart from each other, and a fixing ring 9 is fixedly connected in the groove. The other end of the compression spring 8 is fixedly connected to the corresponding fixing ring 9, thereby resetting the sliding ring 6.

[0033] In this embodiment, guide strips 601 are fixedly connected to the inner walls of the front and rear sides of the groove. The sliding ring 6 is slidably sleeved on the outer side of the corresponding guide strip 601 to guide the sliding ring 6.

The threaded sleeve 7 rotates horizontally by engaging with the threaded rod 101, and the sliding ring 6 is driven to move horizontally synchronously by the engagement of the limiting ring and the sliding ring 6. The sliding ring 6 moves horizontally via the oblique... The engagement of the hole and the inclined rod 5 causes the two clamping plates 4 located on the same side to move closer to each other, so that the clamping plates 4 are dislodged from the slots and the protective cover 2 is released. This allows the protective cover 2 to be replaced separately when the anti-stick coating 3 is damaged, while the forming roller body 1 can continue to be used. By fitting the new protective cover 2 onto the outside of the forming roller and installing it in place, and then rotating the annular plate 11 in the opposite direction, the clamping plates 4 are driven into the slots to fix the protective cover 2. Then, the fastening bolt 10 is rotated in the opposite direction to insert it into the positioning groove and lock the annular plate 11, thereby realizing the installation of the protective cover 2.
