Description

Technical Field

[0001] This utility model belongs to the field of coating machine technology, and in particular relates to a coating machine for processing heat-resistant composite food-grade silicone paper. Background Technology

[0002] Food-grade silicone paper is a specially treated paper used for baking and food packaging. It is made by uniformly coating or laminating a layer of food-grade silicone oil (usually an organosilicon compound) onto a base paper. This material is widely used in food processing and home cooking due to its safety, heat resistance, non-stick properties, and moisture resistance.

[0003] The coating machine is one of the core pieces of equipment in the production of silicone paper. Its main function is to uniformly and precisely coat the surface of the base paper with food-grade silicone oil. Utility model patent document CN219604040U discloses a silicone oil coating machine for bamboo pulp silicone paper processing. Through the interaction of an internally threaded tube, a lead screw, a scraper, and a limiting post, the height of the lead screw is adjusted by turning a screw block, and the height of the scraper is adjusted accordingly. Observing the scale indicated by the pointer allows for precise adjustment of the scraper height, enabling timely removal of excess silicone oil passing under the scraper and achieving precise control of the silicone oil coating thickness. However, adjusting the scraper position through a purely mechanical structure is still relatively coarse, making fine-tuning difficult and thus compromising the quality of the silicone paper. Furthermore, the connection between the scraper and the supporting bending plate in this technology is complex, and replacing the scraper after wear is difficult. Therefore, improvements to the existing coating machine are still needed. Utility Model Content

The support cylinder 4 guides the base paper Z, and the scraper 5 scrapes off the excess silicone oil on the base paper Z. The pneumatic control adjustment mechanism is located inside the machine body 1 on one side of the support cylinder 4. A gap is formed between the coating roller 3 and the roller 2 for the base paper Z to pass through. The scraper 5 cooperates with the support cylinder 4 to scrape off the excess silicone oil on the surface of the base paper Z. In this embodiment, the coating roller 3 can adopt the structure in the patent document with publication number CN219604040U, that is, the coating roller 3 has a silicone oil receiving chamber in the middle of its interior, and a number of oil outlet branches connected to the silicone oil receiving chamber are evenly distributed on the surface of the coating roller 3. A servo motor is set outside the machine body 1 to drive the coating roller 3 to rotate. At this time, the coating roller 3 cooperates with the roller 2 to coat the silicone oil on the surface of the base paper Z. In this embodiment, the pneumatic control mechanism includes: a fixed base 6, a mounting base 7, two sets of airbags 8, and two sets of air sources 9; Please see Figure 1 The mounting base 6 is disposed in the body 1. For example, please refer to [reference needed]. Figure 3 or Figure 8 A mounting plate 604 is provided on the side of the fixed base 6 away from the mounting base 7. The mounting plate 604 is provided with mounting holes. The fixed base 6 can be installed inside the machine body 1 by means of threaded fasteners cooperating with the mounting holes. Please see Figure 2 or Figure 3 or Figure 5 or Figure 6 One end of the mounting base 7 can be fitted with a scraper 5. For example, the mounting base 7 is provided with a disassembly groove 701, and one end of the scraper 5 can extend into the disassembly groove 701. The disassembly groove 701 is provided with multiple positioning holes that penetrate the side wall of the disassembly groove 701. Please refer to [link to relevant documentation]. Figure 4 The scraper 5 has multiple mating holes that are adapted to the positioning holes at one end of the disassembly and assembly groove 701. When one end of the scraper 5 is inserted into the disassembly and assembly groove 701, the mating holes and the positioning holes are in opposite positions. At this time, the scraper 5 can be fixed in the disassembly and assembly groove 701 by threaded fasteners. The threaded fasteners can be bolts or nuts. In this embodiment, please refer to Figure 2 The mounting base 7 is rotatably connected to the fixed base 6 via a main shaft 10 parallel to the axis of the support cylinder 4; for details, please refer to [link to relevant documentation]. Figure 7 The fixed base 6 is provided with two mounting blocks 601, which are located at both ends of the spindle 10. The two ends of the spindle 10 are detachably connected to the two mounting blocks 601 respectively; please refer to Figure 5 The mounting base 7 is provided with a connecting through hole that is compatible with the spindle 10. During installation, the spindle 10 passes through the connecting through hole and connects to the two mounting blocks 601. At this time, the end of the mounting base 7 can swing with the spindle 10 as the fulcrum. Please see Figure 1 and Figure 2 Both sets of airbags 8 are positioned between the mounting base 7 and the fixed base 6, and are respectively located on both sides of the main shaft 10. The airbags 8 can control volume changes through gas. For details, please refer to [link to relevant documentation]. Figure 1 Two sets of air sources 9 are installed on the body 1, and air nozzles 801 are installed on the air bags 8. The air sources 9 are connected to the air nozzles 801 through hoses. The two sets of air sources 9 can inflate or deflate the two sets of air bags 8 respectively. For example, the air source 9 can be an electric air pump equipped with a precision pressure regulating valve to achieve precise control of air pressure. In this embodiment, please refer to Figure 7 The fixing base 6 is provided with two sets of connectors, which are respectively positioned opposite to the two sets of airbags 8. Each set of connectors includes a positioning plate 602 and a limiting plate 603. The airbags 8 are mounted on the positioning plate 602. For example, the airbags 8 are provided with end plates for connecting to fixed objects. The airbags 8 are fixed to the positioning plate 602 by the end plates and threaded fasteners. The positioning plate 602 is provided with through holes. Please refer to [link to relevant documentation]. Figure 3 The air nozzle 801 on the airbag 8 can pass through the through hole and connect to the hose; The limiting plate 603 is located at the end of the airbag 8 away from the positioning plate 602, and is used to limit the other end of the airbag 8; the limiting plate 603 can be fixedly connected to the fixing base 6. At this time, the airbag 8 needs to be installed on the fixing base 6 first, and then the fixing base 6 is connected to the mounting base 7. In this embodiment, the limiting plate 603 is preferably detachably connected to the fixing seat 6, which facilitates the disassembly and assembly of the airbag 8 when the mounting seat 7 and the fixing seat 6 are not disassembled, thereby improving the overall flexibility of the air control adjustment mechanism.

[0029] In this embodiment, please refer to Figure 5 The mounting base 7 is provided with contact grooves 702 on the side close to the fixed base 6 and on both sides of the main shaft 10. The two sets of airbags 8 extend into the two contact grooves 702 respectively, which increases the contact area, improves the force transmission efficiency, and restricts the lateral displacement of the airbags 8, thereby enhancing the stability of the structure.

[0030] according to Figure 1 The orientation sequence is as follows: when the airbag 8 on the side closer to the scraper 5 is inflated and the other set of airbags 8 is deflated, the scraper 5 is adjusted away from the support cylinder 4, and the distance between the scraper 5 and the support cylinder 4 increases; when the airbag 8 on the side farther from the scraper 5 is inflated and the other set of airbags 8 is deflated, the scraper 5 is adjusted towards the support cylinder 4, and the distance between the scraper 5 and the support cylinder 4 decreases; by controlling the air pressure of the airbags 8 on both sides of the main shaft 10, the angle of the scraper 5 can be continuously finely adjusted, thereby controlling the silicone oil coating thickness.
