Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, and in particular to a lightweight multi-layer composite lining production device. Background Technology

[0002] Composite lining refers to clothing made by bonding two or more fabrics together through a special process. Its inner layer usually contains a composite structure or lining design. Composite lining garments often use hot melt adhesive (such as TPU adhesive) or oil adhesive to bond different fabrics together. For example, a fleece layer of polyester fiber (polyester) is combined with an outer normal fabric to achieve warmth and windproof functions.

[0003] In the processing of composite linings, hot pressing is a commonly used composite process. Steel rollers with built-in electric heating modules generate heat, which, combined with pressure, causes multiple layers of fabric to be tightly bonded under the action of heat. However, in actual production, the composite fabric needs to move continuously with the conveying equipment. If the equipment vibrates or causes other interference during this process, the fabric may shift in position. Some areas may overlap or wrinkle due to the shift. These wrinkled areas are difficult to detect quickly. Furthermore, when the steel rollers directly apply hot pressing to these wrinkled areas, it will cause uneven local pressure and heating, which will lead to quality problems such as fabric delamination and poor bonding. Therefore, a lightweight multi-layer composite lining production device is proposed. Utility Model Content

These wrinkled areas are difficult to detect quickly, and when the steel roller directly applies hot pressure to these wrinkled areas, it will cause uneven local pressure and heating, which will lead to the problem of fabric delamination.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams.

[0022] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention, which provides a lightweight multi-layer composite lining production device. When the composite lining fabric has layers or wrinkles, it can quickly identify the uneven state of the fabric and stop the transport immediately so as to adjust the composite lining and prevent delamination. It includes: a belt conveyor 100, a pressure detection unit 200 and a hot pressing unit 300. The conveyor belt of the belt conveyor 100 is supported by a built-in, closely distributed rotating drum, and a control box 101 is fixedly connected to one side of the belt conveyor 100. A pressure detection unit 200 is provided on the belt conveyor 100, which includes a rolling part 201 and a monitoring and sensing part 202. When the rolling part 201 rolls and contacts the fold, it triggers the monitoring and sensing part 202. The monitoring and sensing part 202 is used to shut down the belt conveyor 100 after triggering. The hot pressing unit 300 installed on the belt conveyor 100 includes a lifting part 301 and a hot pressing part 302. The lifting part 301 is used to drive the hot pressing part 302 to move up and down, and the hot pressing part 302 is used to hot press the composite lining fabric.

[0023] The belt conveyor 100 supports the conveyor belt through built-in closely distributed rotating drums to transport the composite lining fabric. The composite lining fabric passes through the pressure detection unit 200 and the hot pressing unit 300 in sequence. The rolling part 201 rolls and contacts the lining fabric. When the fabric is layered or wrinkled, the rolling part 201 rolls and contacts the wrinkled area, thereby triggering the monitoring sensor 202. After the monitoring sensor 202 is triggered, it sends the sensing information to the control box 101, and the control box 101 shuts down the belt conveyor 100 to stop the fabric transport. After the workers have finished processing and the fabric is flat, the belt conveyor 100 will continue to transport the fabric. During hot pressing, the lifting unit 301 drives the hot pressing unit 302 to descend. The hot pressing unit 302 performs hot pressing composite on the fabric during normal conveying. When the belt conveyor 100 stops due to wrinkles, the lifting unit 301 drives the hot pressing unit 302 to rise, avoiding hot pressing on uneven areas and ensuring processing quality.

[0024] Example 2 Reference Figures 1-3 This is the second embodiment of the present invention. Unlike the previous embodiment, the rolling part 201 includes a support frame 201a fixedly connected to the top of the belt conveyor 100. Multiple T-shaped plates 201b slide through the bottom of the inner cavity of the support frame 201a. The multiple T-shaped plates 201b are distributed in a matrix staggered manner in the same horizontal plane. A roller frame 201c is fixedly connected to the bottom of each T-shaped plate 201b. A rotating roller 201d that passes through the roller frame 201c is rotatably connected to the inner wall of each roller frame 201c.

[0025] The T-shaped plate 201b can slide vertically at the bottom of the support frame 201a. Multiple rollers 201d are divided into front and rear groups. The gap between adjacent rollers 201d in the front group is covered by the rear rollers 201d to ensure no dead angle contact with the composite lining. When the composite lining fabric is conveyed, the rollers 201d roll in contact with the fabric surface. The sliding characteristics of the T-shaped plate 201b can be flexibly adjusted according to the undulations of the fabric surface. If it comes into contact with a wrinkle, the protrusion on the fabric surface will push the rollers 201d upward, thereby causing the T-shaped plate 201b to be lifted by force, thus triggering the monitoring sensor 202.

[0026] Each roller frame 201c has a bearing 201e embedded on both sides, and the two ends of the roller 201d pass through the two bearings 201e embedded in the roller frame 201c.

[0027] The bearing 201e reduces the frictional resistance between the roller 201d and the roller frame 201c, making the roller 201d roll more smoothly when it contacts the fabric, avoiding the impact of jamming on the sensitivity to wrinkles, and ensuring the stability of the rolling contact.

[0028] In addition, the monitoring sensing unit 202 includes a plurality of pressure sensors 202a fixedly connected to the top of the inner cavity of the support frame 201a. Each pressure sensor 202a is distributed above the corresponding T-shaped plate 201b. A connecting plate 202b is fixedly connected to the bottom of the sensing end of each pressure sensor 202a. A rubber column 202c that contacts the T-shaped plate 201b is fixedly connected to the bottom of each connecting plate 202b.

[0029] The rubber column 202c is made of rubber material with a certain hardness and retains the ability to deform. When the fabric wrinkles and pushes the roller 201d to move upward, the T-shaped plate 201b simultaneously pushes the rubber column 202c and the connecting plate 202b. The rubber column 202c deforms under force and transmits the force to the pressure sensor 202a. After sensing the pressure change, the pressure sensor 202a converts the wrinkle signal into an electrical signal to monitor the unevenness of the fabric. The electrical signal is transmitted to the control box 101, which controls the belt conveyor 100 to shut down.

[0030] Example 3 Reference Figure 1 and Figure 4 This is the third embodiment of the present invention. Unlike the previous embodiment, the lifting part 301 includes a support frame 301a fixedly connected to the top of the belt conveyor 100. An electric telescopic rod 301b is fixedly installed on the top of the support frame 301a. The telescopic end of the electric telescopic rod 301b slides through the support frame 301a and is fixedly connected to a connecting frame 301c.

[0031] The support frame 301a serves as the load-bearing foundation. When the electric telescopic rod 301b extends or retracts, it drives the connecting frame 301c to move linearly along the axis of the telescopic rod, thereby controlling the height of the connecting frame 301c and providing driving force for the lifting and lowering of the hot pressing section 302.

[0032] Two balance bars 301d are fixedly connected to the top of the connecting frame 301c, and both balance bars 301d slide through the support frame 301a.

[0033] During the lifting and lowering process of the connecting frame 301c driven by the electric telescopic rod 301b, the sliding cooperation between the balance rod 301d and the support frame 301a restricts the lateral displacement of the connecting frame 301c, ensuring that the connecting frame 301c rises and falls smoothly in the vertical direction, so that the hot pressure roller 302a maintains a horizontal posture when in contact with the fabric, avoiding uneven heat pressure caused by tilting.

[0034] In addition, the hot pressing part 302 includes a hot pressing roller 302a rotatably connected to the inner wall of the connecting frame 301c. The hot pressing roller 302a has a hollow inner cavity design, and an electric heater 302b is fixedly connected to the inner cavity of the hot pressing roller 302a.

[0035] The electric heater 302b has a built-in resistance wire and heats up by energizing the resistance wire. After the electric heater 302b is energized, it heats up and the heat is conducted to the surface of the hot press roller 302a. When the connecting frame 301c drives the hot press roller 302a to descend and contact the fabric, the fabric moves. The hot press roller 302a, which rotates by friction, applies pressure and heat to the composite lining fabric through its high surface temperature, thereby achieving hot pressing composite of multiple materials.

[0036] In addition, bearings 302c are embedded on both sides of the connecting frame 301c, and the two ends of the hot press roller 302a pass through the inner rings of the two bearings 302c respectively.

[0037] The inner ring of the bearing 302c embedded on both sides of the connecting frame 301c is tightly fitted with both ends of the hot pressing roller 302a, and the outer ring is fixed to the connecting frame 301c. During the hot pressing process, the bearing 302c reduces the frictional resistance when the hot pressing roller 302a rotates, allowing the hot pressing roller 302a to rotate freely under the drive of the fabric conveyor, ensuring the continuity and smoothness of the hot pressing process.

[0038] During use, the composite lining fabric is driven along the conveying path by the belt conveyor 100, passing through the pressure detection unit 200 and the hot pressing unit 300 in sequence. The control box 101 serves as the core control hub, coordinating the operation of each component. During the fabric conveying process, the rolling part 201 is in continuous contact with the fabric surface, and the multiple rotating rollers 201d at its bottom make rolling contact with the fabric without dead angles. When the fabric is layered or wrinkled, the raised part pushes the rotating rollers 201d upward, causing the T-shaped plate 201b to rise synchronously, thereby squeezing the rubber column 202c of the monitoring and sensing part 202. After the rubber column 202c is deformed by the force, it transmits the pressure to the pressure sensor 202a through the connecting plate 202b, which converts the wrinkle signal into an electrical signal and sends it to the control box 101. After receiving the signal, the control box 101 immediately shuts down the belt conveyor 100. After the worker adjusts the fabric to a flat state, the conveyor is restarted to continue running. During normal fabric conveying, the electric telescopic rod 301b of the lifting unit 301 extends and retracts, driving the connecting frame 301c to descend smoothly, ensuring that the hot press roller 302a is in horizontal contact with the fabric. The electric heater 302b inside the hot press roller 302a heats up through the resistance wire, and the heat is conducted to the roller surface. When the fabric moves, the friction force drives the hot press roller 302a to rotate. The hot press roller 302a achieves the composite of multiple layers of fabric through surface high temperature and pressure. When the belt conveyor 100 stops due to wrinkles, the lifting unit 301 drives the hot press unit 302 to rise, causing the hot press roller 302a to detach from the fabric, avoiding quality problems caused by hot pressing on uneven areas. After the fabric returns to flatness and is conveyed again, the hot press unit 302 descends again to continue the hot pressing composite operation.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
