Description

Technical Field

[0001] This utility model relates to the field of material bonding processing technology, specifically to a composite material bonding machine. Background Technology

[0002] In the field of composite material processing, hot pressing is a core process for achieving multi-layer substrate bonding, such as films, fabrics, and metal foils. Through the high temperature and pressure of hot press rollers, substrates with different properties are tightly bonded to form composite materials with functions such as waterproofing, wear resistance, and shielding. These composite materials are widely used in industries such as packaging, electronics, automotive interiors, and medical dressings. Because the soft substrates to be bonded, such as knitted fabrics, thin PET films, and non-woven fabrics, are highly flexible and have low stiffness, tension fluctuations in the unwinding mechanism during the substrate conveying process before being conveyed to the hot press rollers can cause local relaxation of the substrate, resulting in stacked wrinkles. This includes the surface of soft substrates being prone to attracting dust or lint due to static electricity, or slight shrinkage due to changes in humidity in the storage environment, forming irregular fine wrinkles. If these wrinkles are not eliminated before hot pressing, they will be compacted by high temperature and pressure after entering the hot press rollers, forming permanent wrinkles or interlayer bubbles. This can lead to substandard appearance of the composite material, functional failure, or even the scrapping of batches of products, increasing production costs. In view of this, we propose a composite material bonding machine. Utility Model Content

[0003] To address the aforementioned shortcomings of existing technologies, this utility model provides a composite material laminating machine that effectively solves the problem that in the hot pressing lamination process of composite materials, soft substrates, due to their high flexibility and low stiffness, are prone to wrinkles before being conveyed to the hot pressing rollers due to fluctuations in unwinding tension, electrostatic attraction, and humidity changes. If these wrinkles are not eliminated, they will be compacted by the hot pressing rollers, leading to substandard appearance, functional failure, batch scrapping, and increased costs of the composite materials.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a composite material bonding machine, including a main unit, including a support, two sets of hot pressure rollers disposed inside the support, and a drive mechanism disposed on the support for driving the two sets of hot pressure rollers to rotate. The leveling unit includes a leveling mechanism mounted on a support for high-pressure blowing of materials, a transmission mechanism mounted on the support for transmission cooperation with a drive mechanism, the transmission mechanism being used to drive the leveling mechanism to move and start and stop, and a limiting mechanism mounted inside the support.

[0005] Furthermore, the drive mechanism includes a motor fixedly connected to one side of the bracket. The motor is fixedly connected to one end of any one of the two sets of hot press rollers via an output shaft. The ends of the two sets of hot press rollers away from the motor are connected by a synchronous gear assembly.

[0006] Furthermore, the leveling mechanism includes a fan fixedly connected to the top of the support, and the output end of the fan is fixedly connected to two sets of inclined strip-shaped hoods through connecting hoses, and the two sets of strip-shaped hoods are symmetrically distributed.

[0007] Furthermore, the transmission mechanism includes a synchronous bevel gear assembly that is connected at one end of either of the two sets of hot press rollers via a synchronous belt pulley assembly, and the synchronous belt pulley assembly is connected to a crank via the synchronous bevel gear assembly.

[0008] Furthermore, a connecting rod two is rotatably connected to the end of the crank away from the synchronous bevel gear assembly, and a slider is rotatably connected to the end of the connecting rod two away from the crank.

[0009] Furthermore, the slider has a second guide rod inside, the top of which is fixedly connected to the inner wall of the bracket, and the inner wall of the second guide rod has two sets of switch buttons for starting and stopping the fan.

[0010] Furthermore, both sides of the slider are rotatably connected to connecting rod 1, and the ends of the two sets of connecting rod 1 away from the slider are rotatably connected to the surface of the strip-shaped hood. The surfaces of the two sets of strip-shaped hood are slidably connected to guide rod 1, and both ends of guide rod 1 are fixedly connected to the inner wall of the bracket.

[0011] Furthermore, the limiting mechanism includes a flat plate fixedly connected to the inner wall of the bracket, and two sets of symmetrically distributed limiting wheels are fixedly connected to the top of the flat plate.

[0012] The technical solution provided by this utility model has the following advantages compared with the known public technology: This invention utilizes a linkage design between a drive mechanism and a transmission mechanism. The drive mechanism synchronously drives the hot press roller to rotate and the transmission mechanism to operate. This allows the transmission mechanism to drive the movement of the blower shroud and the start-stop rhythm of the blower, matching the speed at which the hot press roller conveys the material. This ensures that the material undergoes high-pressure airflow wrinkle removal just before it reaches the hot press roller, preventing some wrinkled material from entering the hot press and forming permanent wrinkles. The invention also employs a combination of limiting and supporting mechanisms to ensure smooth and unbiased material conveying, thereby guaranteeing the bonding quality and pass rate of the composite material.

Detailed Implementation

[0016] 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.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] like Figures 1 to 4As shown, a composite material bonding machine includes a main unit 100, a support 101, two sets of hot press rollers 102 disposed inside the support 101, and a drive mechanism 103 disposed on the support 101 for driving the two sets of hot press rollers 102 to rotate. The drive mechanism 103 includes a motor 1031 fixedly connected to one side of the support 101. The motor 1031 is fixedly connected to one end of any one set of hot press rollers 102 via an output shaft. The ends of the two sets of hot press rollers 102 away from the motor 1031 are connected by a synchronous gear assembly 1032. The synchronous gear assembly 1032 consists of two sets of radially meshing gears, which can drive the two sets of hot press rollers 102 to rotate synchronously when the motor 1031 outputs. It should be noted that the two sets of hot press rollers 102 can be connected to external heating equipment. When two or more sets of materials enter between the two sets of hot press rollers 102, the materials are heated by the two sets of hot press rollers 102, and at the same time, the materials are bonded together by the rotation pressure. Furthermore, the leveling unit 200 includes a leveling mechanism 201 mounted on the support 101 for high-pressure air blowing on the material. The leveling mechanism 201 includes a fan 2011 fixedly connected to the top of the support 101. The output end of the fan 2011 is fixedly connected to two sets of inclined strip-shaped air hoods 2012 via connecting hoses, and the two sets of strip-shaped air hoods 2012 are symmetrically distributed. The two sets of strip-shaped air hoods 2012 are symmetrically arranged with an outward V-shape. Through the output of the fan 2011, high-pressure airflow can be sprayed onto the surface of the material that has not been pressed and bonded using the strip-shaped air hoods 2012. After the high-pressure airflow is sprayed onto the surface of the material, the airflow will form a transverse directional combing force along the material. The airflow pressure is used to smooth the material to both sides of the edge, avoiding direct contact with the material and causing frictional displacement, while achieving wrinkle removal. Specifically, a transmission mechanism 202, mounted on the bracket 101, is used to drive the leveling mechanism 201 to move and start / stop. The transmission mechanism 202 includes a synchronous bevel gear assembly 2022, one end of any one of the two sets of hot press rollers 102 being driven by a synchronous pulley assembly 2021. A crank 2025 is driven by the synchronous pulley assembly 2021 through the synchronous bevel gear assembly 2022. A connecting rod 2026 is rotatably connected to the end of the crank 2025 away from the synchronous bevel gear assembly 2022. A slider 2028 is rotatably connected to the end of the connecting rod 2026 away from the crank 2025. A guide rod 2027 is slidably connected inside the slider 2028. The top of the guide rod 2027 is fixedly connected to the inner wall of the bracket 101. Two sets of switch buttons 2029 for starting and stopping the fan 2011 are fixedly connected to the inner wall of the second rod 2027. The two sides of the slider 2028 are rotatably connected to the first connecting rod 2023. The ends of the two sets of first connecting rods 2023 away from the slider 2028 are rotatably connected to the surface of the strip-shaped wind shroud 2012. The surfaces of the two sets of strip-shaped wind shrouds 2012 are slidably connected to the first guide rod 2024. The two ends of the first guide rod 2024 are fixedly connected to the inner wall of the bracket 101. The synchronous belt pulley assembly 2021 consists of two sets of synchronous pulleys and a set of synchronous toothed belts. It is used for transmission between the synchronous bevel gear assembly 2022 and the hot press roller 102. At the same time, the synchronous bevel gear assembly 2022 consists of two sets of bevel gears that mesh vertically. So that when the motor 1031 drives the hot press roller 102 to rotate, it can synchronously drive the crank 2025 to rotate. It should be noted that when crank 2025 rotates, slider 2028 is limited by guide rod 2027, and can be driven by connecting rod 2026 to repeatedly move up and down. Because the two sets of strip-shaped fan shrouds 2012 are limited and guided by guide rod 2024, when slider 2028 moves upward, connecting rod 2023 can drive the two sets of strip-shaped fan shrouds 2012 to move closer together; conversely, when slider 2028 moves downward, connecting rod 2023 can drive the two sets of strip-shaped fan shrouds 2012 to move away from each other. When slider 2028 reaches its highest point, the top of slider 2028 can press the switch button 2029 on the top of the inner cavity of guide rod 2027, thereby turning on fan 2011. After the blower 2011 is turned on, the slider 2028 begins to move downward under the action of the transmission mechanism 202. The two sets of strip-shaped air hoods 2012 move away from each other. While moving away, the strip-shaped air hoods 2012 can spray strip-shaped high-pressure airflow onto the material surface to eliminate wrinkles in the material. When the slider 2028 moves to the bottom, the bottom of the slider 2028 can press the switch button 2029 at the bottom of the inner cavity of the guide rod 2027, thereby turning off the blower 2011. This prevents the airflow from being sprayed onto the material surface again when the two sets of strip-shaped air hoods 2012 come together to reset, which would cause new wrinkles in the material. At the same time, the two sets of switch buttons 2029 are electrically connected to the blower 2011 and the external power supply through wires, which can realize the rapid start and stop of the blower 2011. Specifically, a limiting mechanism 203 is installed inside the support 101. The limiting mechanism 203 includes a flat plate 2031 fixedly connected to the inner wall of the support 101. Two sets of symmetrically distributed limiting wheels 2032 are fixedly connected to the top of the flat plate 2031. The flat plate 2031 is located below the material. When the strip hood 2012 sprays airflow onto the surface of the material, it can provide support for the material, preventing excessive airflow from causing deformation of the material and affecting the normal conveying of the material. At the same time, by setting two sets of symmetrically distributed limiting wheels 2032 on the flat plate 2031, which can be respectively set on both sides of the material, the material is guided and limited when it is conveyed and when the strip hood 2012 sprays high-pressure airflow onto the surface of the material, so as to avoid the material from shifting during the wrinkle removal process and affecting the subsequent bonding quality.

[0019] The working principle of this utility model is as follows: When the equipment is started, the motor 1031 of the drive mechanism 103 in the main unit 100 is energized and outputs power. Its output shaft directly drives any one of the two sets of hot press rollers 102 to rotate. At the same time, the ends of the two sets of hot press rollers 102 away from the motor 1031 are connected by a synchronous gear assembly 1032, so that the two sets of hot press rollers 102 rotate synchronously in opposite directions, providing a rotational conveying and high-temperature pressurization basis for subsequent hot pressing and bonding of materials. The two sets of hot press rollers 102 can be connected to external heating equipment to preheat to the appropriate bonding temperature. Meanwhile, the drive mechanism 103 and the transmission mechanism 202 of the leveling unit 200 are linked: one end of any one of the two sets of hot press rollers 102 drives the synchronous bevel gear assembly 2022 to rotate through the synchronous belt pulley assembly 2021. The synchronous bevel gear assembly 2022 further drives the crank 2025 to rotate, which drives the leveling mechanism 201 to realize the coordinated movement of the strip-shaped wind cover 2012 and the start and stop of the fan 2011. When the crank 2025 rotates, the end away from the synchronous bevel gear assembly 2022 drives the slider 2028 to move through the connecting rod 2026 connected by rotation. Since the slider 2028 is slidably sleeved on the guide rod 2027, the guide rod 2027 forms a vertical limit on the slider 2028, so that the slider 2028 can only move up and down along the guide rod 2027. When slider 2028 moves upward, strip-shaped hoods 2012 move closer to their reset position, triggering the fan 2011 to prepare for startup. When slider 2028 moves upward along guide rod 2027, connecting rod 1 2023 rotatably connected to both sides of slider 2028 simultaneously pushes the two sets of strip-shaped hoods 2012 of the leveling unit 200 blowing mechanism 201 to move. Since the surfaces of the two sets of strip-shaped hoods 2012 are slidably connected to guide rod 1 024, guide rod 1 024 forms a horizontal limit on the strip-shaped hoods 2012, causing the two sets of strip-shaped hoods 2012 to move closer to each other along guide rod 1 024 and return to the initial retracted position. When the slider 2028 moves to its highest position, its top directly presses the switch button 2029 on the top of the inner wall of the guide rod 2027. The switch button 2029 is electrically connected to the blower 2011 and the external power supply through the wire, which triggers the blower 2011 of the flattening mechanism 201 to be powered on and started. The blower 2011 begins to generate high-pressure airflow to prepare for subsequent wrinkle removal. After the blower 2011 is started, the strip-shaped air hood 2012 unfolds and sprays air to achieve non-contact wrinkle removal. After the blower 2011 is started, the slider 2028 moves downward along the guide rod 2027 under the continuous rotation of the crank 2025. At this time, the connecting rod 1 2023 on both sides of the slider 2028 pulls the two sets of strip-shaped air hoods 2012 away from each other along the guide rod 1 2024, and the two sets of strip-shaped air hoods 2012 are symmetrically distributed with an outward V-shape. The high-pressure airflow generated by the blower 2011 is delivered to the two sets of strip-shaped air hoods 2012 through the connecting hose. The airflow is sprayed obliquely through the strip-shaped air hoods 2012 onto the surface of the soft material being conveyed below. High-pressure airflow forms a transverse directional combing force along the material surface, smoothing out the stacked wrinkles caused by tension fluctuations and the irregular fine wrinkles caused by humidity changes towards the edges, thus achieving wrinkle removal; When slider 2028 moves down to its lowest position, strip-shaped air hood 2012 stops spraying air to prevent new wrinkles from forming. When slider 2028 moves down along guide rod 2027 to its lowest position, its bottom presses the switch button 2029 on the bottom of the inner wall of guide rod 2027, triggering the blower 2011 to shut down. At the same time, slider 2028 begins to move upward in the opposite direction, causing the two sets of strip-shaped air hoods 2012 to move closer to each other again. This prevents the strip-shaped air hoods 2012 from continuously spraying air when they move closer to reset, which could cause airflow turbulence and create new wrinkles in the material, thus further ensuring the wrinkle removal effect. During the process of the leveling mechanism 201 spraying high-pressure airflow onto the material, the limiting mechanism 203 of the leveling unit 200 plays a key supporting and guiding role. The leveling plate 2031 of the limiting mechanism 203 is fixed to the inner wall of the bracket 101 and is horizontally set below the material to provide a stable support surface for the material and prevent the material from bulging upward or deviating from the conveying path due to excessive high-pressure airflow. Meanwhile, two sets of symmetrically distributed limiting wheels 2032 fixed to the top of the flat plate 2031 are respectively attached to the two sides of the material. During the process of material being conveyed by the hot press roller 102 and wrinkle removal by airflow, the wheels form a lateral limit on the material, preventing the material from shifting due to airflow impact or conveying deviation. This ensures the alignment when the material enters the two sets of hot press rollers 102, and prevents edge misalignment and other problems caused by material shift during hot pressing. This further improves the bonding quality and pass rate of composite materials.
