Description

Technical Field

[0001] The invention relates to the technical field of glue coating, in particular to a cold stamping aluminum film manufacturing process and glue coating equipment. Background Art

[0002] Aluminum film glue coating is used in many fields. In the packaging industry, it is used for the preparation of aluminum-plastic composite packaging materials to firmly bond aluminum film with plastic film and improve the barrier performance of packaging. In the electronics industry, it can be used to bond aluminum film with circuit boards, display screens and other components to ensure the stability and reliability of electronic equipment. In the construction field, it can be used to bond aluminum film with insulation materials and decorative materials to enhance the functionality of building materials. When applying glue, the glue is transferred to the surface of the aluminum film through a roller. The coating thickness is relatively uniform and the production efficiency is high. It is often used in continuous production scenarios.

[0003] During the gluing process, after the glue is coated on the surface of the glue coating roller, there is still a thin layer of glue. At this time, this layer of glue is thin and easy to solidify, which causes the outer diameter of the glue coating roller to increase and affects the accuracy of the glue coating beam. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A cold stamping aluminum film production process consists of the following steps:

[0006] Step 1: nylon gluing: gluing one side of the nylon film through a gluing device, and drying it through a drying device after the gluing is completed;

[0007] Step 2: Nylon compounding: using a roller compounding device to roll-compound the nylon coated surface with one side of the aluminum foil;

[0008] Step 3: Glue coating on the aluminum foil: glue coating is performed on the other side of the aluminum foil through glue coating equipment, and then drying is performed again;

[0009] Step 4: PVC compounding: compounding the PVC film with the adhesive surface of the aluminum foil through a compounding device, so that the nylon film and the PVC film wrap the aluminum foil to form an aluminum film;

[0010] Step 5: Cutting and packaging: Cut the composite aluminum film according to size and package it for storage after cutting.

[0011] A glue coating device, used to implement the glue coating in step three, comprising:

[0012] A frame, a top pressing mechanism is fixedly installed on the top of the frame, and the top pressing mechanism is used to apply pressure on the non-glue-coated surface of the material;

[0013] A gluing mechanism, which is used to store glue and apply glue to the gluing surface of the material, the gluing mechanism is installed inside the frame, and the gluing mechanism is located below the top pressing mechanism, and a motor is fixedly installed on the outside of the gluing mechanism;

[0014] A guide mechanism, which is used to position the material and clean the glue-coated surface of the material, and is installed on the outside of the frame;

[0015] The glue coating mechanism includes a glue bin, a bottom plate is fixedly connected to the bottom of the glue bin, two ends of the bottom plate are fixedly connected to the inner wall of the frame, the bottom of the inner wall of the glue bin is an inclined surface and the end away from the guide mechanism is inclined downward, and the inner wall of the glue bin is rotatably installed with a transmission shaft and a fixed shaft, the transmission shaft is a fixed shaft, and the transmission shaft is located obliquely below the side of the fixed shaft away from the guide mechanism, and a glue coating roller is fixedly installed at the center position of the outer side of the fixed shaft, and the glue coating roller cooperates with the scraper plate, and continues to rotate after the glue coating roller coats the surface of the material with glue, and the glue remaining on the surface of the glue coating roller is scraped off by the scraper plate The scraped glue is guided to the top of the stirring roller by the scraper plate to avoid the glue remaining on the surface of the glue coating roller from being easily solidified due to its small amount and thin thickness, which increases the outer diameter of the glue coating roller after long-term rotation and affects the thickness accuracy of the glue coating. At the same time, the stirring roller is used to stir the uncoated glue so as to avoid the waste of solidification caused by long-term static glue. Connecting blocks are fixedly installed on both sides of the top of the inner wall of the glue bin, and a scraper plate is fixedly installed on the bottom of the connecting block. The scraper plate is tightly fitted close to the outer side of the glue coating roller, and the scraper plate is tilted downward at the end away from the glue coating roller.

[0016] Preferably, a stirring roller is fixedly installed on the outside of the transmission shaft, and spiral convex strips are evenly arranged on the outside of the stirring roller, and one end of the stirring roller is connected to the output end of the motor, and an outer baffle is fixedly connected to the top of the glue bin near the guide mechanism. Shaft blocks are fixedly installed on both sides of the top of the outer side of the outer baffle, and scrapers are slidably installed on the outside of the shaft block. The scrapers cooperate with the side wheels, and during the rotation of the glue coating roller, the area to be coated with glue is quickly scraped to scrape off excess glue, thereby improving the uniformity of glue coating. At the same time, during the scraping process, the side wheels cooperate with the side wheels, and the side wheels cooperate with the annular groove on the surface of the side wheels by utilizing the characteristic that the outer diameter of the side wheels is smaller than the glue coating roller, so that the scraped excess glue is diverted to both sides and finally falls back into the glue bin to avoid glue overflow. A screw is rotatably installed at the center position of the outer side of the outer baffle, and the outer side of the screw is threadedly connected to the inner wall of the scraper, and side wheels are fixedly installed on both sides of the outer side of the fixed shaft, and annular grooves are provided on the outer sides of the side wheels.

Elastic plates are fixedly installed on both sides of the top of the annular groove plate, and the elastic plates cooperate with the rubber gaskets. During the process of applying glue and applying pressure, through its own elastic deformation characteristics, when the material passes through the material faster, the pressing roller moves obliquely upward, increasing the pressure while reducing the pressure between the pressing roller and the material. The distance between the glue coating rollers ensures the pressure when the glue contacts the material, and avoids the glue from being unable to be smoothly coated due to the glue passing through speed being too fast. The top of the elastic plate is fixedly connected to the bottom of the top plate, and the two ends of the outer side of the sliding shaft are rotatably installed with side ring covers, and the side ring covers are located between the ring groove plates, and the inner walls of the side ring covers are fixedly installed with rubber gaskets, and the inner walls of the rubber gaskets are fixedly connected with a pressing roller, and the pressing roller cooperates with the glue coating roller and utilizes the staggered inclination between the pressing roller and the glue coating roller to increase the contact area between the material and the glue coating roller when passing through, so that the contact time between the material and the glue coating roller is increased during coating, thereby ensuring smooth coating of the glue, and the pressing roller is located obliquely above the glue coating roller on the side close to the guide mechanism.

[0018] Preferably, the guide mechanism includes a connecting arm, which is symmetrically installed along the center position of the axis of the frame, and a slide plate is fixedly installed on the opposite end of the connecting arm away from the glue coating mechanism, and a guide roller is rotatably connected to the opposite side of the slide plate close to the glue coating mechanism. Both ends of the outer side of the guide roller are fixedly installed with a rubber cylinder, and the rubber cylinder cooperates with the guide roller to make the rubber cylinder contact with both sides of the material when in contact, thereby increasing the contact area with the material under contact pressure to prevent the material from slipping. At the same time, the rubber cylinder cooperates with the guide roller to make the material A slight depression appears at the center position to guide the material when it passes through, so as to avoid the material from shifting during transmission and affecting the accuracy of the material coating position.

Sliding rollers are slidably installed between the slide plates, and the two ends of the sliding rollers are slidably adapted to the empty grooves of the convex plates, and elastic rings are installed at the empty grooves of the convex plates, and the bottom of the elastic ring fits with the two ends of the sliding rollers. A fixing rod is fixedly installed on the side of the top of the slide plate away from the gluing mechanism, and a brush cylinder is fixedly installed on the outer side of the fixed rod.

[0019] The present invention provides a glue coating device having the following beneficial effects:

[0020] 1. The glue coating equipment cooperates with a glue coating roller and a glue scraper. After the glue coating roller coats the surface of the material with glue, it continues to rotate. The glue remaining on the surface of the glue coating roller is scraped off by the glue scraper, and the scraped glue is guided to the top of the stirring roller by the glue scraper to prevent the glue remaining on the surface of the glue coating roller from being easily solidified due to its small amount and thin thickness, resulting in an increase in the outer diameter of the glue coating roller after a long rotation, affecting the thickness accuracy of the glue coating. At the same time, the stirring roller is used to stir, so that the uncoated glue is always stirred, avoiding the glue from being stationary for a long time and causing curing waste.

[0021] 2. The glue coating equipment cooperates with the scraper and the side wheel. During the rotation of the glue coating roller, the area to be coated with glue is quickly scraped to scrape off excess glue, thereby improving the uniformity of glue coating. At the same time, during the scraping process, the scraping equipment cooperates with the side wheel, utilizing the characteristic that the outer diameter of the side wheel is smaller than that of the glue coating roller and the annular groove on the surface of the side wheel, so that the scraped excess glue is diverted to both sides and finally falls back into the glue bin to avoid glue overflow.

[0022] 3. The glue coating equipment cooperates with the elastic plate and the rubber gasket. During the process of applying glue pressure, through its own elastic deformation characteristics, when the material passes through the equipment at a faster speed, the pressure is increased and the distance between the pressure roller and the glue coating roller is reduced, thereby ensuring the pressure when the glue contacts the material and preventing the glue from being unable to be coated smoothly due to the glue passing through the equipment at a too fast speed.

[0023] Fourth, the glue coating equipment, through the cooperation of the nip roller and the glue coating roller, utilizes the staggered inclination between the nip roller and the glue coating roller to increase the contact area between the material and the glue coating roller when passing through, so that the contact time between the material and the glue coating roller is increased during coating, thereby ensuring smooth coating of the glue.

[0024] 5. The glue coating equipment cooperates with the rubber cylinder and the guide roller. When in contact, the rubber cylinder contacts both sides of the material, increasing the contact area with the material under contact pressure to prevent the material from slipping. At the same time, the rubber cylinder cooperates with the guide roller to make a slight depression in the center of the material to guide the material when it passes through, avoiding the material from shifting during transmission and affecting the accuracy of the material coating position.

[0048] The gluing mechanism 2 includes a glue bin 202, the bottom of which is fixedly connected to a bottom plate 201, and both ends of the bottom plate 201 are fixedly connected to the inner wall of the frame 1. The bottom of the inner wall of the glue bin 202 is an inclined surface and the end away from the guide mechanism 4 is inclined downward. The motor 5 drives the stirring roller 208 to rotate through the transmission shaft 207, so that the stirring roller 208 rotates and at the same time, the spiral convex strips on the outside drive the glue above to rotate to the side away from the gluing roller 211, and then move from the bottom to the direction of the gluing roller 211. During the rotation, the glue is stirred by the spiral convex strips. When gluing, the nylon material of the material is contacted through the cooperation of the top pressing mechanism 3, and the material is pressed downward, so that the aluminum foil of the material contacts the gluing roller 211, so that The glue adhered to the surface of the glue coating roller 211 cooperates with the pressure of the top pressing mechanism 3, so that when the material passes through, the glue coating roller 211 is driven to rotate, and the surface glue is coated on the surface of the aluminum foil, and the inner wall of the glue bin 202 is rotatably installed with a transmission shaft 207 and a fixed shaft 209, the transmission shaft 207 is fixed to the shaft 209, and the transmission shaft 207 is located obliquely below the side of the fixed shaft 209 away from the guide mechanism 4, and the glue coating roller 211 is fixedly installed at the center position of the outer side of the fixed shaft 209, and connecting blocks 212 are fixedly installed on both sides of the top of the inner wall of the glue bin 202, and a scraper plate 213 is fixedly installed at the bottom of the connecting block 212, and the scraper plate 213 is tightly fitted close to the outer side of the glue coating roller 211, and the end of the scraper plate 213 away from the glue coating roller 211 is tilted downward.

[0049] A stirring roller 208 is fixedly installed on the outer side of the transmission shaft 207, and spiral convex strips are evenly arranged on the outer side of the stirring roller 208. One end of the stirring roller 208 is connected to the output end of the motor 5. The top of the glue tank 202 close to the guide mechanism 4 is fixedly connected to the outer baffle plate 203. Both sides of the outer top of the outer baffle plate 203 are fixedly installed. A scraper 205 is slidably installed on the outer side of the shaft block 206. After the glue roller 211 is coated, it continues to rotate and passes through the scraper plate 213. The glue not coated on the surface of the aluminum foil is scraped off, and the scraped glue is transferred to the oblique upper side of the stirring roller 208 through the inclination of the scraper plate 213. After the glue is scraped off, the glue coating roller 211 adheres to the glue again after reaching the bottom. A screw 204 is rotatably installed at the center position of the outer side of the outer baffle 203, and the outer side of the screw 204 is threadedly connected to the inner wall of the scraper 205, and side wheels 210 are fixedly installed on both sides of the outer side of the fixed shaft 209, and annular grooves are opened on the outer sides of the side wheels 210.

[0050] The third embodiment is based on the first and second embodiments. Figures 6 to 9As shown, the top pressing mechanism 3 includes a top plate 31, both sides of the bottom of the top plate 31 are fixedly connected to the top of the frame body 1, and both sides of the bottom of the top plate 31 near the guide mechanism 4 are fixedly installed with inclined slot plates 32, the bottom end of the inclined slot plate 32 is inclined toward one side of the guide mechanism 4, and a slide groove is provided on the outer side of the inclined slot plate 32, through the elastic force of the elastic plate 38, the annular slot plate 33 is connected with the rotation connection of the slide shaft 35, the slide shaft 35 is driven to slide obliquely downward in the slide groove of the inclined slot plate 32, and the nylon surface of the material is contacted by the pressure roller 34. Under the elasticity of the elastic plate 38, the material is pressed downward, so that the aluminum foil surface of the material contacts the glue coating roller 211, and the contact pressure between the aluminum foil surface of the material and the glue coating roller 211 is increased, so that the glue on the surface of the glue coating roller 211 is smoothly coated on the aluminum foil surface of the material, and the slide shaft 35 is slidably installed at the slide groove of the inclined slot plate 32, and the slide shaft 35 An annular groove plate 33 is slidably installed on both sides of the outer side, and the annular groove plate 33 is located between the inclined groove plate 32. Elastic plates 38 are fixedly installed on both sides of the top of the annular groove plate 33, and the top of the elastic plate 38 is fixedly connected to the bottom of the top plate 31. Side ring covers 36 are rotatably installed on both ends of the outer side of the sliding shaft 35, and the side ring covers 36 are located between the annular groove plates 33. Through the cooperation of the side ring covers 36 and the rubber gaskets 37, the pressure roller 34 is restricted by the side ring covers 36, so that the axis of the pressure roller 34 is always parallel to the axis of the sliding shaft 35, and the rubber gaskets 37 cooperate with the elastic plates 38 to buffer the changes in the material passing speed, and the inner walls of the side ring covers 36 are fixedly installed with rubber gaskets 37, and the inner walls of the rubber gaskets 37 are fixedly connected with the pressure roller 34, and the pressure roller 34 is located obliquely above the side of the glue coating roller 211 close to the guide mechanism 4.

[0051] The guide mechanism 4 includes a connecting arm 41, which is symmetrically installed along the center position of the axis of the frame 1, and a slide plate 44 is fixedly installed on the opposite side of the connecting arm 41 away from the glue coating mechanism 2. A guide roller 42 is rotatably connected to the opposite side of the slide plate 44 close to the glue coating mechanism 2. The material passes through the top of the fixed rod 46, so that the aluminum foil of the material contacts the brush cylinder 45, and then the material passes through the bottom of the slide roller 47, so that the bottom of the slide roller 47 contacts the nylon film of the material. After the material passes through the slide roller 47, it passes through the top of the guide roller 42 and is guided to move toward the glue coating mechanism 2. Rubber cylinders 43 are fixedly installed on both ends of the outer side of the guide roller 42, a convex plate is provided at the center position of the bottom of the slide plate 44, and an empty groove is opened on the outer side of the convex plate, and a slide roller 47 is slidably installed between the slide plates 44, and the two ends of the slide roller 47 are slidably adapted to the empty groove of the convex plate, and an elastic ring 48 is installed at the empty groove of the convex plate. When the material passes through, the moving speed of the material makes the material pass through the material on both sides under the restriction of the guide roller 42 and the fixed rod 46 faster, so that the upward force of the material on the sliding roller 47 is maximized, so that the sliding roller 47 transmits the force to the elastic ring 48, so that the elastic ring 48 is deformed, and the sliding roller 47 slides upward, and at the same time increases the contact pressure between the material and the material. When passing through the guide roller 42, the guide roller 42 and the rubber tube 43 are matched through the pressure of the sliding roller 47, and the rubber tube 43 contacts the material. Under pressure, the contact area of ​​the rubber tube 43 with the material is increased. At the same time, the outer diameter of the rubber tube 43 on both sides is larger than the outer diameter of the guide roller 42, so that a slight depression appears in the center position when the material passes through, and the bottom of the elastic ring 48 fits with the two ends of the sliding roller 47. A fixed rod 46 is fixedly installed on the side of the top of the slide plate 44 away from the glue coating mechanism 2, and a brush tube 45 is fixedly installed on the outside of the fixed rod 46.

[0052] When in use, the material after the aluminum foil and nylon film are composited is driven by the traction device and penetrated by the guide mechanism 4, and the gluing mechanism 2 is driven by the motor 5 to operate, so that the gluing mechanism 2 cooperates with the pressing mechanism 3 to apply glue to the surface of the aluminum foil.

[0053] In the guide mechanism 4, the material passes through the top of the fixed rod 46, so that the aluminum foil of the material contacts the brush cylinder 45, and then the material passes through the bottom of the sliding roller 47, so that the bottom of the sliding roller 47 contacts the nylon film of the material. After the material passes through the sliding roller 47, it passes through the top of the guide roller 42 and is guided to move in the direction of the gluing mechanism 2. When the material passes through, the moving speed of the material makes the material pass through the material on both sides under the restriction of the guide roller 42 and the fixed rod 46 faster, so that the upward force of the material on the sliding roller 47 is maximized, so that the sliding roller 47 transmits the force to the elastic ring 48, so that the elastic ring 48 is deformed, and the sliding roller 47 slides upward, and at the same time increases the contact pressure between the material and the material. When passing through the guide roller 42, the pressure of the sliding roller 47 makes the guide roller 42 cooperate with the rubber tube 43, and the rubber tube 43 contacts the material. Under pressure, the rubber tube 43 increases the contact area with the material. At the same time, the outer diameter of the rubber tube 43 on both sides is larger than the outer diameter of the guide roller 42, so that a slight depression appears in the center position when the material passes through.

[0054] In the gluing mechanism 2, the motor 5 drives the stirring roller 208 to rotate through the transmission shaft 207, so that the stirring roller 208 rotates and at the same time, the glue above is driven to rotate to the side away from the gluing roller 211 through the spiral convex strips on the outside, and then moves from the bottom to the direction of the gluing roller 211. During the rotation, the glue is stirred by the spiral convex strips. When gluing, the nylon material of the material is contacted through the cooperation of the pressing mechanism 3, and the material is pressed downward, so that the aluminum foil of the material contacts the gluing roller. 211, the glue adhered to the surface of the glue coating roller 211 cooperates with the pressure of the top pressing mechanism 3, so that when the material passes through, the glue coating roller 211 is driven to rotate, and the glue on the surface is coated on the surface of the aluminum foil. After the glue coating roller 211 is coated, it continues to rotate, and the glue not coated on the surface of the aluminum foil is scraped off by the scraper plate 213. The scraped glue is transmitted to the oblique upper side of the stirring roller 208 through the inclination of the scraper plate 213. After the glue is scraped off, the glue coating roller 211 adheres to the glue again after reaching the bottom.

[0055] In the pressing mechanism 3, through the elastic force of the elastic plate 38 and the rotational connection between the annular groove plate 33 and the sliding shaft 35, the sliding shaft 35 is driven to slide obliquely downward in the sliding groove of the inclined groove plate 32, and the nylon surface of the material is contacted by the pressing roller 34. Under the elasticity of the elastic plate 38, the material is pressed downward, so that the aluminum foil surface of the material contacts the glue coating roller 211, and the contact pressure between the aluminum foil surface of the material and the glue coating roller 211 is increased, so that the glue on the surface of the glue coating roller 211 is smoothly coated on the aluminum foil surface of the material. At the same time, through the cooperation of the side ring cover 36 and the rubber gasket 37, the pressing roller 34 is restricted by the side ring cover 36, so that the axis of the pressing roller 34 is always parallel to the axis of the sliding shaft 35, and the rubber gasket 37 and the elastic plate 38 cooperate to buffer the material when the speed changes.
