Description

An automatic bonding machine for headband elastic material Technical Field

[0001] This utility model relates to the field of lamination machine technology, specifically to an automatic lamination machine for elastic materials for head straps. Background Technology

[0002] Fabric bonding is typically done using automated bonding machines. Existing bonding methods are divided into two types: one-step bonding, which involves placing the fabric to be bonded and the corresponding hot melt adhesive, then hot-pressing it using a bonding machine, followed by edge trimming; and two-step bonding, which involves coating one side of the fabric with water-based acrylic adhesive, drying it, pressing it together, and then curing it with ultraviolet light. Both methods have their advantages and disadvantages.

[0003] A search revealed that the Chinese patent "A Multi-Laminate Fabric Laminating Machine" (authorization announcement number CN213973023U) includes a base plate. Two fixing plates are fixedly connected to the top of the base plate on both sides, and a pressing box is fixedly connected between the two fixing plates. A filter plate is fixedly connected to the bottom of the pressing box. A shell is fixedly connected to the top of the base plate, and a heating box is fixedly connected to the bottom of the base plate. A heating wire is fixedly connected to the inner cavity of the heating box. Heat generated by the heating wire in the inner cavity of the heating box is drawn upwards by an air pump and blown upwards through a horizontal pipe and nozzle, thereby drying the fabric. This solves the problem that existing laminating machines cannot quickly dry the laminated fabric, thus reducing production efficiency.

[0004] However, the above method has the following drawbacks in actual use: it adopts a direct drying method, which causes the fabric to be suddenly heated, which can easily cause the edges of the fabric to curl and damage the internal fibers of the fabric. This can lead to local overheating of the glue and the generation of air bubbles, affecting the subsequent pressing effect. In addition, it is not easy to recover and utilize the heat energy during the drying process, resulting in energy waste.

[0005] Based on this, this utility model designs an automatic bonding machine for elastic materials of head straps to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic bonding machine for elastic materials of head straps.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic bonding machine for elastic materials for headbands includes a base and a housing mounted on its outer side, and a drying mechanism disposed inside the housing and used for segmented drying of the headbands; wherein, the drying mechanism includes a drying box inside the housing, breathable cotton boards are embedded on both sides of the drying box, and a set of drying grooves are opened on both sides of the drying box.

[0009] Furthermore, the drying mechanism also includes two sets of inclined grooves, which are opened to one side of the drying box and inclined in a direction close to the breathable cotton board.

[0010] Furthermore, a sleeve is fixedly fitted on the outer side of the outer shell, and a set of heating wires is installed inside the sleeve. Two air guide boxes that pass through the outer shell and extend into the sleeve are installed on both sides of the drying box.

[0011] Furthermore, openings are provided on both sides of the outer casing, and two guide rollers are provided inside the openings. Electric push rods are installed at the ends of the guide rollers and are installed inside the outer casing.

[0012] Furthermore, an air pump is provided on the outside of the casing, and a folded pipe communicating with the casing is installed at the output end of the air pump;

[0013] Furthermore, the input end of the air pump is equipped with a three-way pipe, and both ends of the three-way pipe away from the air pump extend into the interior of the housing;

[0014] Furthermore, the frontal cross-section of the drying tank is trapezoidal;

[0015] Furthermore, the drying box is equipped with a partition inside, which is located between the drying trough and the inclined trough;

[0016] Furthermore, two adjacent air guide boxes are symmetrically arranged along the partition;

[0017] Furthermore, the base has two pressure rollers on its top, one of which is driven by a servo motor.

[0018] Beneficial effects

[0019] 1. By setting up a breathable cotton board, an inclined trough, and a drying trough, the breathable cotton board can be used to preheat the fabric for the first stage. Then, the inclined trough sprays out hot air. Compared with the direct exhaust of the drying trough, the inclined method can extend the gas path and reduce the gas temperature, achieving a second stage of preheating. The subsequent drying trough completes the overall drying process. The segmented drying process preheats the fabric step by step, effectively reducing the curling of the fabric edges and the damage to the internal fibers of the fabric. This ensures that the adhesive is heated stably and guarantees the subsequent pressing effect.

[0020] 2. By setting up a three-way pipe, the heat energy inside the outer casing is recovered during the operation of the air pump. Then, it is reintroduced into the casing through the folded pipe for recycling, which is more energy-efficient. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to Figures 1-4 of the specification. An automatic bonding machine for headband elastic material includes a base 100 and a housing 200 mounted on its outer side, and also includes a drying mechanism 300. The drying mechanism 300 is disposed inside the housing 200 and is used to perform segmented drying treatment on the headband. The drying mechanism 300 includes a drying box 310 inside the housing 200. Both sides of the drying box 310 are inlaid with breathable cotton boards 311, and both sides of the drying box 310 are provided with a set of drying grooves 312.

[0031] In this embodiment of the utility model, the user can pre-set a winding mechanism and an unwinding mechanism on both sides of the base 100, and then pass the two fabrics to be bonded through the outer shell 200 in sequence. Then, during the movement of the fabrics, the drying mechanism 300 is used to perform segmented drying treatment on the materials.

[0032] In this embodiment of the invention, during the drying process, heated gas is introduced into the drying box 310, and then the hot gas is slowly released through the breathable cotton board 311 to reduce the amount of hot gas emitted and reduce the contact effect between the hot gas and the fabric, thus preheating the fabric. Then, the drying tank 312 is used to complete the overall drying process of the fabric.

[0033] In some embodiments, as shown in FIG4, as a preferred embodiment of the present invention, the drying mechanism 300 further includes two sets of inclined grooves 320, which are opened to one side of the drying box 310 and inclined in a direction close to the breathable cotton plate 311.

[0034] By using the inclined groove 320, hot air in the drying box 310 can be introduced in an inclined manner while the breathable cotton board 311 completes the preheating treatment, thus extending the gas path, reducing the gas impact force and temperature, and performing a second preheating treatment on the fabric.

[0035] In this embodiment of the utility model, a sleeve 210 is fixedly sleeved on the outer side of the outer shell 200. A set of heating wires 214 are installed inside the sleeve 210. Two air guide boxes 313 are installed on both sides of the drying box 310, which pass through the outer shell 200 and extend into the sleeve 210. The heating wires 214 are used to heat the gas. Then, the sleeve 210 is used to transfer and store the heat energy, and at the same time, the heat energy is covered to the outside of the outer shell 200, which improves the heat preservation effect of the outer shell 200 during the drying process.

[0036] In this embodiment of the utility model, openings are provided on both sides of the outer shell 200, and two guide rollers 215 are provided inside the openings. Electric push rods are installed at the ends of the guide rollers 215 and are installed inside the outer shell 200. The openings facilitate the passage of the corresponding fabric. With the guide rollers 215, the fabric can be guided. When bonding different types of head strap materials, the tension can be adjusted by operating the corresponding electric push rods.

[0037] In this embodiment of the utility model, an air pump 211 is provided on the outside of the housing 210. The output end of the air pump 211 is equipped with a folded tube 212 that communicates with the housing 210. When the air pump 211 is started, gas can be introduced into the housing 210 along the folded tube 212. The gas is heated by the heating wire 214 mentioned above and then used for drying.

[0038] In this embodiment of the utility model, a three-way pipe 213 is installed at the input end of the air pump 211. Both ends of the three-way pipe 213 away from the air pump 211 extend into the interior of the housing 200. By using the three-way pipe 213, the hot air used for drying inside the housing 200 can be collected and then discharged again along the air pump 211 for reuse, reducing heat energy waste. This recycling method makes the whole device more energy-efficient.

[0039] In this embodiment of the invention, the front view cross section of the drying tank 312 is trapezoidal, which allows for a wider range of hot air discharge, ensuring the drying area and reducing the existence of drying dead corners.

[0040] In this embodiment of the invention, a partition 314 is installed inside the drying box 310, and the partition 314 is located between the drying trough 312 and the inclined trough 320. Two adjacent air guide boxes 313 are symmetrically arranged along the partition 314. The inner diameter of the air guide box 313 closer to the breathable cotton board 311 is smaller than that of the air guide box 313 farther away from the breathable cotton board 311. By using the partition 314, the gas discharged from the small inner diameter air guide box 313 and the large inner diameter air guide box 313 can be distributed and transmitted. The gas discharged from the small inner diameter air guide box 313 carries less gas and heat energy. Combined with the influence of the breathable cotton board 311 and the inclined trough 320, the temperature drop effect is better. This can ensure the preheating effect while reducing the impact of high temperature on the fabric. The hot air discharged from the large inner diameter air guide box 313 can directly dry the fabric along the drying trough 312.

[0041] In this embodiment of the utility model, two pressure rollers are provided on the top of the base 100. One of the pressure rollers is driven by a servo motor. The pressure rollers can be used to press the fabric after drying. The specific pressing speed is controlled by the servo motor.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
