Description

Technical Field

[0001] The utility model relates to the technical field of glass wool production, in particular to a glass wool aluminum foil sticking device. Background Art

[0002] Glass wool is a common thermal insulation material made of glass fiber. It has excellent thermal insulation, fire resistance and chemical stability, and is widely used in construction, industrial equipment, HVAC and other fields. Glass wool is light, soft, easy to install and process, and also has good sound absorption performance, which can effectively reduce noise transmission.

[0003] The main purpose of attaching aluminum foil to glass wool is to increase its thermal insulation performance. Aluminum foil has good reflective properties and can reflect most of the heat and light, thereby reducing heat conduction and heat radiation and improving the thermal insulation effect of glass wool. In addition, aluminum foil can also play a role in moisture-proof and anti-corrosion, extending the service life of glass wool.

[0005] The device can spray the glue evenly on the foil, and the foil and glass wool are bonded to form a glass wool felt / board, which has the characteristics of rapid bonding, convenient operation, energy saving, and no damage to the veneer surface. However, the above technical solution uses natural air drying to make the glue bond to the bottom of the glass wool. This method will cause the glue to not dry during the subsequent processing. In addition, the above technical solution uses guide rollers and pressure rollers to vertically transport the foil. The part where the glue is sprayed has no support, and the impact force of the glue may create pits, resulting in uneven glue spraying. Utility Model Content

The device arranges a positioning roller between the aluminum foil unwinding mechanism and the glue spraying mechanism so that the aluminum foil can be conveyed around the positioning roller and then conveyed to the conveying mechanism to be bonded with the bottom of the glass wool. When spraying glue, the positioning roller can provide support for the back of the aluminum foil to ensure that the glue spraying surface of the aluminum foil is in a taut state, making the glue spraying more uniform. In addition, a heating device is also arranged in the positioning roller to heat the aluminum foil with glue, thereby accelerating the curing speed of the glue, so that it can adhere to the glass wool faster and improve the firmness and sealing of the bonding.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A glass wool aluminum foil sticking device comprises a frame, an aluminum foil unwinding mechanism, a positioning roller, and a glue spraying mechanism.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] refer to Figures 1 to 6 A glass wool aluminum foil sticking device comprises a frame 1, an aluminum foil unwinding mechanism 2, a positioning roller 3, and a glue spraying mechanism 4. The frame 1 is provided with a conveying mechanism 11 for conveying glass wool. The glue spraying mechanism 4 and the aluminum foil unwinding mechanism 2 are both connected to the frame 1 and are arranged in sequence along the conveying direction of the conveying mechanism 11. The positioning roller 3 is connected between the aluminum foil unwinding mechanism 2 and the glue spraying mechanism 4. After the aluminum foil of the aluminum foil unwinding mechanism 2 passes around the positioning roller 3, it is bonded to the bottom of the glass wool on the conveying mechanism 11. The positioning roller 3 is also provided with a heating module 31. The glue spraying direction of the glue spraying mechanism 4 is the bonding point between the aluminum foil and the positioning roller 3.

[0020] It should be noted here that the glass wool transported by the conveying mechanism 11 should be processed plate-shaped glass wool. Under this design, the glass wool arrives at the working area of ​​the device under the transportation of the conveying mechanism 11. The operator first adjusts the position of the aluminum foil so that one end of the aluminum foil is attached to the bottom of the glass wool. Then, with the cooperation of the conveying mechanism 11 and the aluminum foil unwinding mechanism 2, the aluminum foil bypasses the positioning roller 3 and moves along the direction of the conveying mechanism 11. The position where the aluminum foil contacts the positioning roller 3 is the glue spraying position of the glue spraying mechanism 4. The glue spraying mechanism 4 will spray glue onto the surface of the aluminum foil at this position. Then, with the cooperation of the conveying mechanism 11 and the aluminum foil unwinding mechanism 2, the aluminum foil with glue will move toward the conveying mechanism 11, bypass the input end of the conveying mechanism 11, enter the bottom of the glass wool, and fit with the bottom of the glass wool.

[0021] In this way, when spraying glue, the positioning roller 3 can provide support for the back side of the aluminum foil, ensuring that the glue spraying surface of the aluminum foil is in a taut state, making the glue spraying more uniform, and a heating module 31 is also provided in the positioning roller 3, which can heat the aluminum foil with glue, accelerate the curing speed of the glue, enable it to adhere to the glass wool faster, and improve the firmness and sealing of the fit.

[0022] In this embodiment, in order to ensure that the glass wool can fit more closely to the aluminum foil, a pressing mechanism 5 is also included. The pressing mechanism 5 is connected to the top of the frame 1 and is located above the conveying mechanism 11. The pressing mechanism 5 is used to press the glass wool down onto the aluminum foil.

[0023] Furthermore, the pressing mechanism 5 includes a support frame 51 connected to the top of the frame 1, and a pressure roller 52 movably connected to the support frame 51. We found that if the glass wool and the aluminum foil are laminated only by the gravity of the glass wool itself, there will be a lot of incomplete lamination on the aluminum foil. By adding the support frame 51 and the pressure roller 52, and the pressure roller 52 is movably connected to the support frame 51, not only can the glass wool pass through the pressure roller 52 under the cooperation of the conveying mechanism 11, and the glass wool is pressed down onto the aluminum foil, but the pressure roller 52 can also adjust the distance between it and the conveying mechanism 11 to adapt to more glass wools with different thicknesses.

[0024] In this embodiment, there are two ways to realize the heating function of the positioning roller 3:

[0025] The first reference Figure 4 The heating module 31 is a heating wire, which is connected to the inside of the positioning roller 3 and heated by electric current. This method is simple and easy to operate, and has a fast heating speed.

[0026] The second reference Figure 5 The heating module 31 is an oil pipeline, through which hot oil is passed into the interior of the positioning roller 3, and the heat of the hot oil is transferred to the positioning roller 3. The heating of the positioning roller 3 is achieved through circulating heating. This method has good heating uniformity and high stability.

[0027] Therefore, this embodiment adopts the second method, that is, the heating module 31 is an oil pipeline.

[0028] Preferably, the glue spraying mechanism 4 includes a support block 41, a spray gun 42, a glue storage barrel 43, and a hose 44. The support block 41 is connected to the frame 1. There are multiple spray guns 42, and multiple spray guns 42 are connected side by side to the support block 41. The glue storage barrel 43 is provided with a glue delivery pipe 431, and the multiple spray guns 42 are respectively connected to the glue delivery pipe 431 through the hose 44.

[0029] In actual work, when the operator starts the spray gun 42, the glue in the glue storage barrel 43 enters the hose 44 through the glue delivery pipe 431 and is transported to the corresponding spray gun 42. The high-pressure air in the spray gun 42 pushes the glue to be sprayed out of the spray gun 42 and the glue is evenly sprayed on the aluminum foil on the positioning roller 3.

[0030] More preferably, there are multiple rubber delivery pipes 431, and each of the rubber delivery pipes 431 is a Y-shaped pipe. The Y-shaped pipe includes an input end connected to the rubber storage barrel 43 and two output ends respectively connected to the hoses 44, and a control valve 4311 is provided on each of the input ends.

[0031] Setting up multiple glue delivery pipes 431 can ensure the uniformity of glue spraying by each spray gun 42. We found that if only one glue delivery pipe 431 is used, and the hose 44 is connected to different positions on the glue delivery pipe 431, the glue sprayed by the spray gun 42 closer to the glue storage barrel 43 will be more sufficient, while the glue sprayed by the spray gun 42 farther away from the glue storage barrel 43 will be less, resulting in uneven glue spraying. After using multiple glue delivery pipes 431, we set a control valve 4311 on the input end of the glue delivery pipe 431, and adjust the glue sprayed by the spray gun 42 by adjusting the control valve 4311, so that the glue sprayed by each spray gun 42 is more uniform.

[0032] In this embodiment, a slope 411 is provided on the support block 41 , and the plurality of spray guns 42 are all connected to the slope 411 . The spraying direction of the spray guns 42 is the contact point between the aluminum foil and the positioning roller 3 .

[0033] Specifically, by providing an inclined surface 411 on the support block 41 , multiple spray guns 42 are connected to the inclined surface 411 . This method can ensure that the inclination angle of each spray gun 42 is uniform, further ensuring the uniformity of glue spraying.

[0034] More preferably, the aluminum foil output end of the positioning roller 3 protrudes from the aluminum foil input end of the conveying mechanism 11. The purpose of this design is to ensure that the aluminum foil is conveyed to the positioning roller 3 and conveyed from the positioning roller 3 to the conveying mechanism 11 at an angle. The inclined conveying of the aluminum foil can effectively prevent sliding, reduce friction, improve production efficiency and protect the surface of the aluminum foil.

[0035] Preferably, the aluminum foil unwinding mechanism 2 is an unwinding roller 21. The purpose of the unwinding roller 21 is to convey the aluminum foil wound on the unwinding roller 21.

[0036] Optionally, the conveying mechanism 11 is a conveyor belt 111. Glass wool is a brittle material that is easily broken and scattered. The use of a conveyor belt 111 can reduce wear and damage to the glass wool. The surface of the conveyor belt 111 is relatively smooth, which can reduce friction on the glass wool and reduce the breakage rate. In addition, the glass wool is prone to scattering during transportation. If it is transported by rollers, there are gaps between the rollers, and the glass wool fragments will fall from the gaps, resulting in scattering. The use of a conveyor belt 111 can fix the glass wool on the belt, reduce scattering, and ensure the safety and cleanliness of the transportation process.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
