Description

Technical Field

[0001] This utility model relates to the technical field of hot melt adhesive laminating machines, specifically to a powder-spreading mechanism for a hot melt adhesive laminating machine. Background Technology

[0002] Hot melt adhesive laminating machines belong to the textile machinery field and are used in the fabric laminating industry. During the fabric laminating process, powder is evenly sprinkled onto the upper surface of a piece of fabric through a powder-sprinkling device. Then, the powder is heated to melt the adhesive powder and bond the two pieces of fabric together, thus achieving the fabric laminating process.

[0003] The uniformity of the adhesive powder on the fabric during the powdering process is crucial to the quality of the subsequent bonding of the two fabrics. Existing powdering mechanisms mostly adopt a mesh-type powdering structure, which relies on the gravity of the powder itself for feeding. Due to the particulate nature of the material, it is easy for the material to get stuck during the feeding process, making it difficult to guarantee the uniformity of the powder feeding. Therefore, a powdering mechanism for a hot melt adhesive laminating machine is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a powder-spreading mechanism for a hot melt adhesive laminating machine to solve the problems mentioned in the background art.

The material conveying roller is rotatably installed inside the protective housing under the drive of the roller drive motor, and the heating seat is located inside the rear side of the protective housing for preheating and fixing the powder spreading. The material spreading mechanism is located at the front of the protective box base. The material spreading mechanism includes a material spreading bin base, a material roller drive motor, and material spreading rollers.

Example

[0018] Please see Figure 1-5 This utility model provides a technical solution: a powder-spreading mechanism for a hot melt adhesive laminating machine, including a protective housing 1, a fabric conveying roller 2, a roller drive motor 3, a heating seat 4, and a powder-spreading mechanism. The fabric conveying roller 2 is rotatably installed inside the protective housing 1 under the drive of the roller drive motor 3 for moving and conveying the fabric. Specifically, see attached... Figure 3 As shown, a material spreading chamber is provided in the middle of the protective box base 1. The material conveying rollers 2 are arranged in pairs. The two sets of material conveying rollers 2 are respectively fixedly and rotatably installed on both sides of the inside of the material spreading chamber by means of a rotating shaft. The roller drive motor 3 is located on the side of the front material conveying roller 2. A reducer is installed on the output side of the roller drive motor 3. The rotating shaft end of the roller drive motor 3 is fixedly installed with the input rotating shaft end of the reducer. The output rotating shaft end of the reducer is fixedly installed with the rotating shaft end of the front material conveying roller 2.

[0019] The material spreading mechanism is located at the front of the protective housing 1 and is used for spreading hot melt adhesive. The material spreading mechanism includes a material spreading bin 5, a material roller drive motor 6, and a material spreading roller 7, as shown in the attached diagram. Figure 3 As shown, the material spreading bin 5 is fixedly installed on the upper front side of the protective box 1 by bolts. To facilitate material storage, two sets of storage chambers are provided inside the material spreading bin 5. Pairs of spreading rollers 7 are driven by a roller drive motor 6 to rotate on a fixed shaft and are installed on both sides of the lower part of the material spreading bin 5. Specifically, the two sets of spreading rollers 7 are rotatably installed on the lower part of the two sets of storage chambers by a rotating shaft. To facilitate quantitative material dispensing, material dispensing grooves are evenly provided on the upper part of the spreading rollers 7. The material dispensing grooves are circumferentially and evenly opened on the outer circle of the spreading rollers 7. The surrounding area employs a grooved roller-type spreading structure. A spreading roller 7, located within the spreading bin 5, spreads the hot melt adhesive material. The spreading roller 7 is rotatably fitted into a groove at the bottom of the spreading bin 5. Grooves are evenly distributed on the upper part of the spreading roller 7. During the rotation of the spreading roller 7, these grooves quantitatively collect the material, which is then released through the groove's rotation. This precise quantitative dispensing significantly improves the uniformity of the hot melt adhesive material spreading. For easier material spreading, see attached... Figure 4 As shown, a material spreading trough 13 is provided at the bottom of both sets of storage chambers.

[0020] The material roller drive motor 6 is used to drive the working of the material spreading roller 7, as shown in the attached diagram. Figure 4 As shown, the material roller drive motor 6 is fixedly installed on the end side of the spreading bin seat 5 by a bracket. In order to realize the working transmission, as shown in the attached figure... Figure 5 As shown, transmission pulleys 11 are fixed on the end shaft sides of both sets of spreading rollers 7. The two sets of transmission pulleys 11 are installed in a staggered manner. Two sets of drive pulleys are installed at intervals on the rotating shaft end of the roller drive motor 6. A transmission toothed belt 12 is installed on the upper part of both sets of drive pulleys and transmission pulleys 11. The spreading rollers 7 are set in pairs and driven synchronously by the roller drive motor 6. While realizing double spreading, the spreading amount can be controlled and adjusted by changing the speed of the spreading rollers 7. The spreading amount can be flexibly controlled and adjusted according to processing needs, which greatly improves the working flexibility of the device.

[0021] Heating seat 4 is located inside the rear side of the protective box 1 for preheating and fixing of the material being spread, as detailed in the attached document. Figure 1As shown, the heating seat 4 is fixedly installed at the rear of the protective box seat 1. The heating seat 4 is equipped with a resistance heater for heating. In order to realize hot air blowing, an air suction fan 8 is installed on the upper part of the heating seat 4. After the fabric is conveyed to the heating area, it is first heated and baked by the resistance heater to melt it. Then, it is heated again by hot air to achieve heat melting and fixing of the fabric. In order to facilitate the hot air discharge, exhaust grooves 9 are opened through both sides of the fabric chamber. In order to prevent hot air from blowing onto the uncured fabric, a middle partition 10 is fixedly installed at a slight inclination in the middle of the fabric chamber.

[0022] Working principle or structural principle: During operation, material is loaded into the interior of the spreading bin 5. The fabric is moved and supported by the fabric conveying roller 2. Driven by the roller drive motor 3, the fabric moves at a constant speed into the protective box 1. At the same time, the material roller drive motor 6 drives the two sets of spreading rollers 7 to rotate synchronously through two sets of transmission toothed belts 12 and transmission pulleys 11. During the rotation, the material is quantitatively collected through the groove on the upper part of the spreading roller 7. Then, the rotation of the spreading roller 7 flips the groove containing the collected material down to the spreading slot 1. 3. The material is evenly sprinkled onto the upper part of the fabric through the sprinkling trough 13. The material is evenly sprinkled by two sets of sprinkling rollers 7. During operation, the amount of material sprinkled can be controlled and adjusted by changing the working speed of the material roller drive motor 6 according to the type of fabric and the bonding requirements. After sprinkling, the fabric is conveyed into the rear heating zone by the fabric conveying roller 2. The hot air provided by the heating seat 4 preheats and melts the hot melt adhesive material particles, realizing the preheating and melting of the sprinkled material. Then the fabric is uniformly sent out of the protective box seat 1 into the next processing equipment.

[0023] In summary, this powder-spreading mechanism adopts a grooved roller-type spreading structure. It utilizes spreading rollers 7, located within the spreading bin 5, to spread the hot melt adhesive material. The spreading rollers 7 are rotatably fitted into the grooves at the bottom of the spreading bin 5, and grooves are evenly distributed on the upper part of the spreading rollers 7. During the rotation of the spreading rollers 7, the grooves quantitatively collect the material, and then the material is released through the groove flipping. This achieves precise quantitative dispensing of the material, greatly improving the uniformity of hot melt adhesive spreading. The spreading rollers 7 are arranged in pairs and synchronously driven by the roller drive motor 6. While achieving dual spreading, the spreading amount can be controlled and adjusted by changing the rotation speed of the spreading rollers 7. The spreading amount can be flexibly controlled and adjusted according to processing needs, greatly improving the operational flexibility of the device.
