Description

Technical Field

[0002] Composite films are widely used in modern industrial production, particularly in food packaging, pharmaceutical packaging, and electronic component packaging, where they play a vital role in protecting and preserving products. With growing environmental awareness and increasing demands for packaging quality, solvent-free composite film production equipment has emerged. This equipment eliminates the need for organic solvents during composite film production, reducing environmental pollution while producing high-quality composite film products, meeting market demand for environmentally friendly packaging materials.

[0003] Traditional composite film production equipment typically uses a solvent-based lamination process. Its mechanical structure primarily consists of an unwinding device, coating device, drying device, laminating device, and winding device. During the coating process, a solvent-containing adhesive is first applied to the substrate film using a doctor blade or roller coating method. The coated film is then heated and dried in a drying device to evaporate the solvent. The multilayer film is then laminated together under pressure in a laminating device, and finally wound up in a winding device.

[0004] However, existing unwinding shaft fixing methods are complex and time-consuming. When replacing a film roll, manually tightening and loosening the bolts and nuts takes a considerable amount of time, resulting in extended equipment downtime and a significant impact on production efficiency. Furthermore, frequent manual operation can easily lead to loose fixation or inconsistent tightness due to human factors, further impacting the stability of the unwinding process and hindering the high-quality production of composite films. Therefore, a solvent-free composite film production equipment was proposed to address these issues. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a solvent-free composite equipment for composite film production, including a composite machine body 1, the side wall of the composite machine body 1 is fixedly connected to a support frame 2, the support frame 2 is provided with a clamping assembly, the support frame 2 is slidably connected to a reel 3, the composite machine body 1 is fixedly connected to a support frame 2 13, the support frame 2 13 is rotatably connected to a coating roller 14, and the side wall of the composite machine body 1 is provided with a filter assembly; the clamping assembly includes a fixed frame 4, the side wall of the fixed frame 4 is fixedly connected to the support frame 2, the side wall of the fixed frame 4 is fixedly connected to a slide plate 5, the slide plate 5 is slidably connected to the inside A slide plate 6 is connected, and a side wall of the slide plate 6 is fixedly connected to a butt plate 7, which is used to fix the unwinding shaft 3. The side wall of the slide plate 6 is fixedly connected to a fixing rod 8, and a connecting rod 11 is rotatably connected inside the fixing frame 4. The connecting rod 11 plays the role of transmitting power to the motor 12, and the side wall of the connecting rod 11 is fixedly connected to a turntable 9. The turntable 9 is used to cause the fixing rod 8 in the curved groove 10 to move accordingly. A curved groove 10 is opened inside the turntable 9, and a motor 12 is provided inside the fixing frame 4. The output end of the motor 12 is connected to the connecting rod 11, and the side wall of the butt plate 7 fits inside the unwinding shaft 3, and the side wall of the fixing rod 8 is slidably connected inside the curved groove 10;

[0034] When the cam 11 is in the working state, the motor 12 is started, the motor 12 drives the connecting rod 11 to rotate, and the connecting rod 11 plays the role of transmitting the power of the motor 12. It transmits the rotation of the motor 12 accurately to the turntable 9, and then drives the turntable 9 to rotate, so as to prompt the fixing rod 8 in the curved groove 10 to move accordingly. As the fixing rod 8 moves, the slide plate 6 slides outward inside the slide plate 5, and the slide plate 5 provides a stable guide and support for the sliding of the slide plate 6 to ensure that the slide plate 6 slides along the predetermined direction. The sliding of the slide plate 6 can convert the movement of the fixing rod 8 into forward pressure and apply pressure forward. This pressure is transmitted to the push plate 7 through the slide plate 6, so that the push plate 7 fixes the unwinding shaft 3. After receiving the pressure, the push plate 7 is in close contact with the unwinding shaft 3, and the unwinding shaft 3 is firmly fixed in the corresponding position by friction and extrusion, ensuring that the unwinding shaft 3 will not shake or shift during the production process, thereby ensuring that the film roll can be stably unwound and the production is carried out smoothly.

[0035] Reference Figure 2 and Figure 4, the filter assembly includes a filter box 15, the filter box 15 is used to filter the absorbed glue mist, the side wall of the filter box 15 is fixedly connected to the side wall of the compound machine body 1, the filter box 15 is fixedly connected to an air pump 16, the air pump 16 input end is fixedly connected to a connecting pipe 17, the side wall of the connecting pipe 17 is fixedly connected to a suction hood 18, the side wall of the connecting pipe 17 is fixedly connected to a fixed block 19, the side wall of the fixed block 19 is fixedly connected to the side wall of the compound machine body 1, the output end of the air pump 16 is fixedly connected to an output pipe 20, the filter box 15 is fixedly connected to an isolation plate 21, the output pipe 20 side wall is fixedly connected to the inside of the isolation plate 21, the filter box 15 is slidably connected to an activated carbon adsorption plate 22, the activated carbon adsorption plate 22 effectively removes some harmful substances in the glue mist and reduces the concentration of the glue mist, the filter box 15 is slidably connected to a molecular sieve plate 23, the molecular sieve plate 23 can further remove residual tiny particles and some low molecular weight harmful substances in the glue mist, further improving the purification effect, the filter box 15 upper surface is fixedly connected to a discharge pipe 24;

[0036] In the coating unit of the composite machine, since the equipment is in a high-speed rotating state during the composite coating process, the glue liquid will have a drawing phenomenon. When these drawn glue liquids are dispersed into the air, glue mist will be formed. At this time, the glue mist problem needs to be solved by starting the air pump 16. The air pump 16 serves as the power source of the entire glue mist treatment system. It can generate suction to form a directional flow of air and glue mist. After the air pump 16 is started, the connecting pipe 17 absorbs the generated glue mist through the suction hood 18. The absorbed glue mist is then transported to the inside of the filter box 15 separated by the isolation plate 21 through the connecting pipe 17 and the output pipe 20. In the filter box 15, the active The carbon adsorption plate 22 can effectively remove some harmful substances in the glue mist, while reducing the concentration of the glue mist and alleviating the harm of the glue mist to the environment and human body. The glue mist is then further removed from the residual tiny particles and some low molecular weight harmful substances by the molecular sieve plate 23. The molecular sieve plate 23 is a material with a uniform microporous structure. It can selectively adsorb according to the size and shape of molecules, further improving the purification effect of the glue mist. Finally, the exhaust pipe 24 is responsible for discharging the purified air, so that the purified air leaves the filter box 15, keeping the air in the working environment fresh, ensuring the health of the operators and the stability of the production environment.

[0037] Working principle: When a new unwinding shaft 3 with a film roll is installed to continue production, first start the motor 12 to drive the connecting rod 11 to rotate, and then drive the turntable 9 to rotate. The rotation of the turntable 9 prompts the fixed rod 8 in the curved groove 10 to move accordingly. As the fixed rod 8 moves, the slide plate 6 slides outward inside the slide plate 5 and applies pressure forward, so that the abutment plate 7 fixes the unwinding shaft 3.

[0038] In the coating unit of the composite machine, due to the high-speed rotation of the equipment, glue liquid will be drawn during the composite coating process, and the glue liquid will be scattered into the air to produce glue mist. It is necessary to start the air pump 16 to make the connecting pipe 17 absorb the generated glue mist through the suction hood 18, and then transport the inhaled glue mist to the inside of the filter box 15 separated by the isolation plate 21 through the connecting pipe 17 and the output pipe 20. The activated carbon adsorption plate 22 can effectively remove some harmful substances in the glue mist and reduce the concentration of the glue mist. Then the molecular sieve plate 23 will further remove the tiny particles and some low-molecular-weight harmful substances remaining in the glue mist, and finally it can be discharged through the exhaust pipe 24 to keep the air in the working environment fresh.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
