Description

Technical Field

[0001] This invention relates to the field of film stretching, and more specifically to a high-speed chain clamp transmission device. Background Technology

[0002] The biaxial stretching process for films involves melting and casting a polymer, then stretching it along both the longitudinal and transverse directions of its plane. After biaxial stretching, the polymer chains tend to align parallel to the film plane, resulting in uniform strength across the film surface and significantly increased strength compared to before stretching, making it less prone to breakage. With the development of the packaging industry, the demand for flexible plastic packaging is constantly increasing. Simultaneously, film manufacturers are increasing the capacity requirements of each production line to reduce costs. While increased production speed leads to higher film output, the performance of the film has decreased due to increased capacity. One reason is that during the transverse stretching process in biaxial stretching, the high temperature and high speed environment cause the temperature resistance, stability, precision, and automation performance of the transverse stretching process to still not meet standards.

[0003] The high-speed chain clamp is a key component of a biaxially oriented film production line. Its main function is to clamp the thick film from the previous process section and move it along the guide rail in the transverse stretching system. In high-speed, large-scale biaxially oriented film production lines, the chain clamp experiences complex forces on the guide rail, including its own weight, the tension force of the hydraulic cylinder, the driving force of the sprocket, the lateral counter-tension force of the film on the chain clamp, and the rotational force of the chain clamp itself at the guide rail's arc or bend. These factors directly affect the operational stability of the film production line, film breakage, ripple vibration, edge film wrinkling, and uneven stretching, making it a significant bottleneck restricting the production line speed. Under high-speed operation, the chain clamp is prone to detachment, unstable operation, and guide rail wear, severely impacting production line speed and film product quality. Chain clamps need to be adaptable to plastic films of different materials. In high-speed production lines, using existing chain clamps to hold wide and thin films, or films with low mechanical strength under heat, results in significant shear force on the film at the clamping point when the clamp shank closes. This can easily cause the film to break or tear, affecting production line operation and reducing film output and quality. Most existing technologies, both domestically and internationally, use mechanical opening and closing clamps to lift and press the clamp shank to complete the opening and closing action. During opening and closing, each clamp shank is subjected to impact force, and the friction between the clamping surface of the shank and the clamping opening of the clamp body leads to wear on the clamping opening and shank. Domestic and international production line equipment manufacturers are designing a chain clamping device that prevents the chain clamp from contacting the clamp shank and also prevents the clamp shank from suddenly closing to reduce impact.

[0004] In the industry, chain clamp structures are mainly sliding and rolling structures, with corresponding sliding and rolling guide rails. Sliding chain clamps have two special wear-resistant sliders, one above the other, secured to a continuous metal guide rail. Sliding chain clamps operate very smoothly with low vibration and noise, and are widely used in high-speed, large-scale production lines. However, this type of equipment operates on sliding friction, with a large friction area and a high coefficient of friction, placing high demands on the wear-resistant sliders. They need to be highly wear-resistant, heat-resistant, and corrosion-resistant, and China has not yet made breakthroughs in key technologies for wear-resistant materials. Rolling guide rails have rigid contact with the rolling chain clamps, requiring the guide rails to have a certain degree of hardness, as well as heat resistance and wear resistance. Domestic heat treatment methods often fail to meet these requirements, leading to frequent guide rail wear or breakage, necessitating frequent downtime for replacement of spare guide rails, resulting in significant economic losses for customers.

[0005] In summary, the chain clamp plays a crucial role in the transverse stretching of biaxially oriented film stretching machines. However, when increasing the speed of biaxially oriented film production lines, issues such as the stability of the production line, the significant impact force on the film during chain clamp opening and closing, and problems like film breakage, ripple vibration, edge wrinkling, and uneven stretching under high speed and high temperature conditions remain to be addressed.

[0039] Furthermore, the drive motor is a torque motor.

[0040] The beneficial effects of this invention are: 1. In this invention, the drive unit and the chain clamp unit cooperate with each other. From the drive motor, sprocket, chain, chain seat, buckle device to the clamp seat, an orderly connection and transmission method is constructed to build a complete and reasonable power transmission link. It can effectively convert the power of the drive motor into the cyclic motion of the clamp seat, so that the high-speed chain clamp transmission device can operate stably and continuously. This ensures that the film is transported according to the predetermined route and speed under the drive of the chain clamp, which is conducive to improving production efficiency and the consistency of product processing quality. In addition, the width adjustment device adopts a screw structure and is equipped with a rotating handle at the movable end. By rotating the handle to rotate the screw structure, the horizontal distance of the guide rail unit can be adjusted. This design can easily adjust the guide rail spacing according to the specific requirements of different film specifications or production processes, which enhances the adaptability of the device to the production of different products and expands the application range of the device. Moreover, the drive motor is equipped with an external motor cooling system to avoid performance degradation, shortened life or even failure and damage caused by overheating of the drive motor, thereby improving the reliability and service life of the drive motor and ensuring that the entire drive unit and the high-speed chain clamp transmission device can work stably for a long time. 2. Compared with the traditional contact-type opening and closing clamp structure, the non-contact opening and closing clamp unit of this invention can significantly reduce mechanical friction between the clamp and the guide rail and other components during the opening and closing process. This not only reduces the wear rate of the components and extends their service life, but also reduces the adverse effects of wear debris on equipment operation, making the film run more smoothly on the guide rail. This helps to improve the speed stability and positional accuracy of film transmission, thereby improving the stability of the entire production process and product quality. By combining the mechanical opening and closing device and the magnetic opening and closing device, when the magnetic opening and closing device fails, the mechanical opening and closing device can intervene in time to close or open the clamp handle, ensuring that the entire non-contact opening and closing clamp unit will not be paralyzed due to the failure of a single device. This ensures the continuity of production, greatly reduces downtime and production losses caused by equipment failure, and improves the reliability and stability of the entire equipment during long-term operation. 3. In this invention, the chain holder, the buckle device, and the clamp holder are all connected by a buckle. During equipment operation, this ensures the relative position of each component is stable, effectively transmitting power and motion. This allows the clamp holder to move accurately in a cyclic manner following the chain's movement, while ensuring the clamp handle is always in the correct working position. This enables stable clamping or releasing of the film, improving the reliability and stability of the entire chain clamp unit. Furthermore, the inner wall of the groove in the middle of the buckle device is provided with a wear-resistant layer and slides in contact with the slide rail in the guide rail unit. The bottom outer side is provided with a wear-resistant structure and slides on the guide rail. When the chain clamp unit moves on the guide rail unit, its movement status can be observed at any time, continuously improving the chain clamp unit's movement on the guide rail unit.

The drive unit 1 is connected to the guide rail unit 2; The contactless opening and closing clamp unit 3 and the chain clamp unit 4 are mounted on the guide rail unit 2. The chain clamp unit 4 is powered by the drive unit 1 and performs cyclic motion on the guide rail unit 2. The contactless opening and closing clamp unit 3 controls the opening and closing of the chain clamp unit 4. The hot air circulation unit 5 is located outside the guide rail unit 2. It provides hot air to the high-speed chain clip transmission device to simulate the transmission state of the chain clip unit 4 at high temperature. The lubrication unit 6 is located on the outlet drive unit 102 and provides lubricating oil to the chain clamp unit 4 to ensure that the chain clamp unit 4 slides smoothly; The intelligent control unit 7 is connected to the drive unit 1 and the hot air circulation unit 5, and is used to monitor and control the drive unit 1 and the hot air circulation unit 5.

[0044] In this embodiment, both the inlet drive unit 101 and the outlet drive unit 102 include a drive motor 11, a width adjustment device 12, a sprocket 13, and a motor cooling system 14. The drive motor 11 is connected to the sprocket 13 through a transmission shaft. The drive motor 11 transmits power to the sprocket 13 through the transmission shaft, causing the sprocket 13 to rotate. The direct connection between the drive motor 11 and the sprocket 13 can effectively transmit the power generated by the drive motor 11 to the sprocket 13, reducing power loss during transmission and improving the overall working efficiency of the device. The width adjustment device 12 allows the device to flexibly adjust the width according to different working requirements, enhancing the adaptability and versatility of the device. The inlet drive unit 101 is located on the film inlet side of the high-speed chain clip transmission device, and the outlet drive unit 102 is located on the film outlet side of the high-speed chain clip transmission device. The inlet drive unit 101 also includes a sprocket tensioning cylinder, which is installed between the guide rail unit 2 and the drive unit 1; The guide rail unit includes, in sequence, an inlet guide rail 201, an intermediate guide rail 202, an outlet guide rail 203, and a guide rail support frame. The two ends of the intermediate guide rail 202 are fixedly connected to the inlet guide rail 201 and the outlet guide rail 203, respectively. The guide rail support frame is installed below the inlet guide rail 201, the intermediate guide rail 202, and the outlet guide rail 203 to support the guide rail unit 2. Both the inlet guide rail 201 and the outlet guide rail 203 are equipped with non-contact opening and closing clamp units 3; The contactless opening and closing clamp unit 3 includes a mechanical opening and closing device and a magnetic opening and closing device; The chain clamp unit 4 includes a chain 401, a chain seat 402, a buckle device 403, a clamp handle 404, a clamp seat 405, and a spring sleeve 406; The chain clamp unit 4 is continuously and tightly installed on the inlet guide rail 201, the intermediate guide rail 202 and the outlet guide rail 203; The hot air circulation unit 5 includes, in sequence, a fan 501, a heater 502, and an oven 503; The lubrication unit 6 includes, in sequence, an oil tank, a piston pump, an oil passage block, an outlet oil injection device, and a waste oil discharge device; The sprocket 13 meshes with the chain 401, the chain 401 is mounted on the chain seat 402 by a pin, the chain seat 402 is mounted with the buckle device 403 by a buckle, and the clamp seat 405 is mounted on the other side of the buckle device 403. The drive motor 11 works to transmit power to the sprocket 13 through the transmission shaft. Under the drive of the sprocket 13, the chain 401 moves in a directional manner, thereby driving the clamp seat 405 to move in a cyclic manner. The width adjustment device 12 is located on the drive unit 1 and the guide rail unit 2. The width adjustment device 12 includes a lead screw structure, which includes a fixed end and a movable end. In the guide rail unit 2, the fixed end is fixed on the intermediate guide rail 202. In the drive unit 1, the fixed end is fixed on the support frame connecting the inlet drive unit 101 and the outlet drive unit 102 to the guide rail unit 2. Each movable end is equipped with a rotating handle. The rotating handle drives the lead screw structure to rotate and adjust the horizontal distance between the inlet guide rail 201, the intermediate guide rail 202 and the outlet guide rail 203. The width adjustment device 12 at the inlet guide rail 201 and the outlet guide rail 203 is located below the drive motor 11. The width adjustment device 12 adjusts the position of the inlet guide rail 201 and the outlet guide rail 203. The width adjustment device 12 at the intermediate guide rail 202 is located on the side of the intermediate guide rail 202 and moves along with the width adjustment device 12 at the inlet guide rail 201 and the outlet guide rail 203 to adjust the movement direction and degree of freedom of the intermediate guide rail 202. The width adjustment device 12 adjusts the inlet guide rail 201, the intermediate guide rail 202 and the outlet guide rail 203 by a distance of 700mm in the horizontal direction. The sprocket 13 is mounted above the drive motor 11 and is coaxially arranged with the drive motor 11; The sprocket tensioning cylinder is installed between the inlet guide rail 201 and the drive motor 11 of the inlet drive unit 101. The sprocket tensioning cylinder is used to keep the chain 401 in the chain clip unit 4 in a tensioned state. In the transmission system, if the chain 401 is too loose, it will cause poor meshing between the sprocket 13 and the chain 401. When the sprocket 13 rotates, the loose chain may skip teeth, affecting the stable transmission of power. The sprocket tensioning cylinder can provide appropriate tension to ensure that the chain 401 is always tightly meshed with the sprocket 13, making the process of power being transmitted from the drive motor 11 to other components through the sprocket 13 more smooth and reliable. The motor cooling system 14 includes a water tank and a water pump. The water pump circulates water from the water tank into the drive motor 11 for cooling. During the long-term operation of the drive motor 11, a large amount of heat is generated. If it is not dissipated in time, the temperature of the drive motor 11 will become too high, affecting the performance and lifespan of the drive motor 11. The motor cooling system 14 can effectively reduce the temperature of the drive motor 11, ensuring that the drive motor 11 operates in a suitable temperature environment, extending the service life of the drive motor 11, reducing the downtime of the device due to the failure of the drive motor 11, and improving the overall reliability and production efficiency of the device.

A spring sleeve 406 is installed on the outside of the spring. The spring is used to control the clamp handle 404 to close tightly or open. The oven 503 surrounds the intermediate guide rail 202, providing a relatively sealed structure inside the guide rail. The fan 501 is connected to the heater 502 through a pipe, and the heater 502 is connected to the oven 503 through a circulation pipe. The fan 501 heats the gas through the heater 502, and then the gas enters the oven 503 from the inlet side through the circulation pipe to heat the chain clamp unit 4 and the guide rail unit inside the oven 503.

The inlet and outlet of the oven 503 are arranged in the same direction as the inlet and outlet of the film; The oven 503 has a split structure. The mounting plates on both sides of the oven 503 are detachable and are used for the inspection and maintenance of the internal structural components of the oven 503. The side of the oven 503 is designed with observation holes for monitoring the operating status of the chain clamp unit 4 inside the oven 503.
