Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of hot cutting device of laminator. BACKGROUND

[0002] Lamination is an important process link in textile and manufacturing industry, which involves bonding different materials (such as fabric, film, glue, etc.) together by a specific method to form a whole. Common lamination methods: 1. Fabric lamination, which means bonding different fabric together to form a whole. This lamination method is widely used in garment manufacturing, hat manufacturing, home supplies and automotive interior, etc. 2. Cloth film lamination, which means bonding fabric and film or waterproof and breathable film together by a specific method. This lamination method is particularly common in garment manufacturing, used for making waterproof and breathable clothing such as windbreaker and snowsuit.

[0003] There are many varieties of fabric base cloth materials, each with its own characteristics and suitable for different clothing and purposes. At the same time, there are also multiple categories of film materials and base cloth materials. Therefore, due to the differences in purpose, demand field, etc., the base cloth material, film material and base cloth material for lamination can be combined in many ways. The diversity of lamination often causes inconsistencies in the width of the base cloth material and the film material, as well as the base cloth material, which can lead to a series of problems such as uneven thickness of the cloth edge, abnormal curling, adhesive transfer, downtime, poor appearance quality, etc. In actual production, the cloth edge often needs to be cut.

[0004] The existing lamination process uses a cold cutting process, which has the following disadvantages: 1. The blade wears out a lot, and needs to be replaced about once a week, which is costly in terms of consumables; 2. Simple mechanical cutting can produce burrs, lint and other abnormalities, and the fabric appearance is poor; 3. Lint is light and easy to be affected by static electricity, and cannot be completely absorbed onto the fabric or removed by the suction pump, which can float in the air like dust, causing pollution to the production environment; 4. Due to the differences in fabric, film and base cloth materials, it is often difficult to accurately assess the service life of the cold cutting knife, resulting in increased downtime, lint sticking to the fabric and other finished product B-grade rates.

[0005] As can be seen, there are problems with lamination without cutting, and the cold cutting process still has problems, so a cutting device needs to be developed to improve existing problems and meet the needs of the lamination field. INVENTION CONTENTS

[0026] The application discloses a hot cutting device of a laminating machine, which comprises a rack 1, a first motor 20, a positioning screw 8, an air pump 6, a hot cutter fixing frame 5, a hot cutter 16, a second motor 14 and a supporting roller 11, the positioning screw 8 is in transmission connection with the motor, the positioning screw 8 is movably arranged on the rack 1, that is, the positioning screw 8 is in threaded connection with the rack 1. In order to enhance the stability of the positioning screw 8, a screw support is arranged on the rack 1, the screw support is fixedly connected with the rack 1, and the positioning screw 8 is arranged in the screw support. The positioning screw 8 comprises a first screw and a second screw, and the first screw and the second screw are oppositely arranged on the rack 1. Specifically, the first screw is arranged on a first screw support 4, and the second screw is arranged on a second screw support 7.

[0027] The air pump 6 is fixedly arranged on the hot cutter fixing frame 5, one end of the air pump 6 is fixedly provided with a hot cutter base 2, a fixed groove 17 is formed in the hot cutter base 2, and the hot cutter 16 is detachably arranged in the fixed groove 17. One end of the hot cutter fixing frame 5 is fixedly arranged on the positioning screw 8, and the hot cutter fixing frame 5 is arranged on the first screw and the second screw. A guide rail 9 is arranged on the rack 1, the guide rail is fixedly arranged on the rack 1 along the length direction of the positioning screw 8, and the hot cutter fixing frame 5 is movably arranged on the guide rail 9 and can slide leftward and rightward on the guide rail 9.

[0028] The second motor 14 is in driving connection with the supporting roller, the supporting roller is rotatably arranged on the rack 1, and the supporting roller is located below the hot cutter. The hot cutter is internally provided with a heating wire, and can generate heat after being electrified. The laminated fabric is located on the supporting roller 11, the hot cutter cuts the laminated fabric, and the laminated fabric is cut off under the reaction force of the supporting roller. In the embodiment, the supporting roller 11 is a roller.

[0029] In the embodiment, the first motor 20 is in transmission connection with the positioning screw 8 through bevel gears, the bevel gears comprise a first bevel gear 3 and a second bevel gear, the first bevel gear 3 is connected with the transmission shaft of the first motor 20, and the second bevel gear is in transmission connection with the first bevel gear. Specifically, the first motor 20 is fixedly arranged on the rack 1 through a motor fixing device 19, and the first bevel gear 3 is rotatably arranged on the rack 1 through a rotating shaft fixing device 18.

[0030] Further, the hot cutting device further comprises a blowing mechanism, the blowing mechanism comprises a wind pipe support 15, a blower 13 and a wind pipe 12, one end of the wind pipe 12 is connected with the blower, the wind pipe 12 is fixedly arranged on the hot cutter fixing frame 5 through the wind pipe support 15, and the wind pipe support 15 is fixedly connected with the wind pipe 12.

After the edge cutting of the hot cutting device, there is no burr, which reduces the degradation rate of the laminated products and also reduces the complaint rate of customers due to burrs.

[0034] The hot cutting device almost has no lint during cutting, reduces the dust condition of the lamination environment, reduces the abnormal processing rate due to the reverse sticking of the lint to the cloth surface, and at the same time improves the safety and friendliness of the working environment of the employees. At the same time, the hot cutting device improves the utilization rate of the hot cutter. After the hot cutter is heat treated, the edge cutting quality is improved, the wear of the cutter is reduced, the frequency of replacing the material due to the wear of the cutter and the roller is reduced, and the cost of consumables is reduced.
