Description

Technical Field

[0001] This utility model belongs to the field of material processing equipment technology, and specifically relates to a biaxial stretching mold. Background Technology

[0002] Biaxial stretching dies are industrial molds that stretch materials simultaneously or in stages in the longitudinal and transverse directions. Through the synergistic effect of mechanical force and temperature field, molecular chains are oriented, optimizing the mechanical, optical, and barrier properties of the material. The mold typically consists of a heating system, a longitudinal stretching mechanism, a transverse stretching mechanism, and a cooling and shaping device. The heating system precisely controls the temperature to keep the material in the optimal processing state. The longitudinal stretching mechanism generates tension through the speed difference of the rollers. The transverse stretching mechanism uses clamps and tracks to achieve deformation in the width direction. The cooling and shaping device fixes the molecular orientation structure. This mold optimizes the microstructure of the material through multi-physics field control and is widely used in the industrial production of high-performance films, metal sheets, etc.

[0003] However, although existing molds use a sealed design of the heating system to block harmful gases, the high temperature after the material enters the stretching process still causes the internal volatile substances to continue to escape. This escape is difficult to control because the material is exposed to an open environment. It not only pollutes the work space and corrodes equipment parts, but may also pose a threat to the health of operators. The safety hazards are more prominent when processing heat-sensitive materials.

[0004] To address the aforementioned problems, this application proposes a biaxial stretching mold. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a biaxial stretching mold that improves the operational safety of biaxial stretching molds.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional stretching mold, comprising a mold stretching mechanism, a fixed shell disposed above the mold stretching mechanism, an exhaust frame disposed inside the fixed shell, a multi-port pipe frame fixedly connected to the upper surface of the exhaust frame, a telescopic hose fixedly connected to the top of the multi-port pipe frame, two electric push rods snapped into the inner wall of the fixed shell, the telescopic end of each electric push rod being fixedly connected to the upper surface of the exhaust frame, a controller and a placement box disposed above the fixed shell, two filter frames disposed inside the placement box, an exhaust pump disposed above the placement box, the input end of the exhaust pump being fixedly connected to the upper surface of the placement box, and the bottom surface of the placement box being fixedly connected to the top of the telescopic hose.

[0013] As a preferred embodiment of this utility model, a protective shell is fixedly connected to the upper surface of the placement box, and the protective shell is fitted over the outside of the exhaust pump.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figure 1-7 The present invention provides the following technical solution: a biaxial stretching mold, including a mold stretching mechanism 1, a fixed shell 2 is provided above the mold stretching mechanism 1, an exhaust frame 6 is provided inside the fixed shell 2, a multi-port pipe frame 5 is fixedly connected to the upper surface of the exhaust frame 6, a telescopic hose 7 is fixedly connected to the top of the multi-port pipe frame 5, two electric push rods 4 are snapped into the inner wall of the fixed shell 2, the telescopic end of each electric push rod 4 is fixedly connected to the upper surface of the exhaust frame 6, a controller 15 and a placement box 11 are respectively provided above the fixed shell 2, two filter frames 13 are provided inside the placement box 11, an exhaust pump 17 is provided above the placement box 11, the input end of the exhaust pump 17 is fixedly connected to the upper surface of the placement box 11, and the bottom surface of the placement box 11 is fixedly connected to the top of the telescopic hose 7.

[0027] In this embodiment, the mold stretching mechanism 1 generates tension through the speed difference of the rollers, while the telescopic hose 7 can move synchronously with the multi-port pipe frame 5 to ensure the continuity of the gas transmission path. The two filter frames 13 are preferably made of corrosion-resistant materials, such as PP material frames combined with activated carbon filter layers and alkaline adsorption cotton, which can not only efficiently adsorb acidic gases and volatile organic compounds, but also withstand corrosive components in the gas, effectively extending the service life of the filter components and ensuring stable and reliable purification effect. Furthermore, the controller 15 adopts a programmable logic controller (PLC), which is a digital computing and operating electronic system designed specifically for industrial environments. It stores operation instructions such as logic operations, sequential control, and timing counting through a programmable memory, and realizes precise control of various machines or production processes through digital or analog input / output interfaces.

[0028] Specifically, support plates 3 are fixedly connected to both sides of the mold stretching mechanism 1. The upper surfaces of the two support plates 3 are fixedly connected to the bottom surface of the fixed shell 2. In this embodiment, a stable support structure is constructed by the support plates 3, and the fixed shell 2 is firmly mounted above the mold stretching mechanism 1 to ensure that the fixed shell 2 remains stable during the exhaust operation and avoids positional displacement due to vibration or external force. This ensures the normal operation of components such as the exhaust frame 6 and the multi-channel pipe frame 5, and provides a reliable installation foundation for the exhaust purification system.

[0029] Specifically, a reinforcing ring 8 is fixedly connected to the outer surface of each electric push rod 4, and the bottom surface of each reinforcing ring 8 is fixedly connected to the upper surface of the fixed shell 2. In this embodiment, the reinforcing ring 8 enhances the installation stability of the electric push rod 4. During the process of the electric push rod 4 frequently driving the exhaust frame 6 to rise and fall, the reinforcing ring 8 can effectively distribute the force and prevent the connection between the electric push rod 4 and the fixed shell 2 from loosening or deforming due to long-term force, thus ensuring the stability and reliability of the operation of the electric push rod 4, and thereby ensuring that the exhaust frame 6 can accurately adjust its height and conform to the material surface to achieve efficient gas collection.

[0030] Specifically, two sets of support rods 9 are fixedly connected to the bottom surface of the placement box 11. The bottom end of each support rod 9 is fixedly connected to the upper surface of the fixed shell 2. In this embodiment, the placement box 11 is suspended and fixed above the fixed shell 2 by the support rods 9, so that a stable spatial structure is formed between the placement box 11 and the fixed shell 2. This design can not only ensure the installation space of equipment such as the filter rack 13 and the exhaust pump 17 inside the placement box 11, but also avoid the placement box 11 from directly contacting the fixed shell 2 and causing friction or interference. At the same time, it enhances the structural stability of the placement box 11 during the exhaust purification process and prevents the vibration generated by the operation of the exhaust pump 17 from affecting the performance of the equipment.

[0031] Specifically, a sealing door 10 is movably hinged to the left side of the placement box 11, and a handle 12 is fixedly connected to the left side of the sealing door 10. In this embodiment, the combination design of the sealing door 10 and the handle 12 provides a convenient maintenance channel for the placement box 11. When it is necessary to replace the filter material in the filter rack 13 or to inspect the inside of the placement box 11, the operator can easily open the sealing door 10 through the handle 12 and quickly enter the inside of the box. At the same time, when the sealing door 10 is closed, it can effectively prevent gas leakage during the purification process, ensure the negative pressure environment inside the placement box 11, and ensure the purification effect and operational safety.

[0032] Specifically, the bottom surface of the controller 15 is fixedly connected to the mounting plate 14, and the bottom surface of the mounting plate 14 is fixedly connected to the upper surface of the fixed shell 2. In this embodiment, the mounting plate 14 provides a flat and firm mounting surface for the controller 15, so that it fits tightly with the fixed shell 2, which facilitates the wiring connection and signal transmission between the controller 15 and devices such as the electric push rod 4 and the exhaust pump 17.

[0033] Specifically, a support base 18 is fixedly connected to the bottom surface of the exhaust pump 17. The bottom surface of the support base 18 is fixedly connected to the upper surface of the placement box 11. In this embodiment, the support base 18 plays a dual role of shock absorption and support. When the exhaust pump 17 is running at high speed, it can effectively buffer vibration and prevent vibration from being transmitted to the placement box 11 and other components, preventing resonance from affecting the performance of the equipment or causing the connection to loosen. In addition, the support base 18 can also raise the installation height of the exhaust pump 17, making it easier for the air inlet of the exhaust pump 17 to be connected to the placement box 11 and optimizing the gas transmission path.

[0034] Specifically, a protective shell 16 is fixedly connected to the upper surface of the placement box 11. The protective shell 16 is fitted over the outside of the exhaust pump 17. In this embodiment, the protective shell 16 can effectively block external dust, debris and accidental collisions from damaging the exhaust pump 17, while reducing the noise generated during the operation of the exhaust pump 17. In addition, the protective shell 16 can also prevent operators from accidentally contacting the rotating parts of the exhaust pump 17, eliminating safety hazards and ensuring the safe operation of the equipment and the safety of personnel.

[0035] The working principle and usage process of this utility model are as follows: In use, the heat-treated material to be processed is first placed on the mold stretching mechanism 1. The difference in linear velocity between different rollers in the mold stretching mechanism 1 generates longitudinal tension, which, in conjunction with the transverse stretching mechanism, completes the bidirectional stretching action of the material. Before starting, the operator can preset the descent height parameters of the exhaust fan 6 through the controller 15 to ensure it is close to the material surface during stretching. After starting, the electric push rod 4 drives the exhaust fan 6 downward according to the command of the controller 15. At this time, the telescopic hose 7 extends and retracts synchronously with the multi-port pipe frame 5, preventing the gas transmission pipeline from bending and becoming blocked due to the operation of the stretching mechanism. Subsequently, the controller 15 triggers the exhaust pump 17 to start, which forms a negative pressure system through the air inlet at the top of the placement box 11, allowing the escaping volatile gases to... The gas enters the placement box 11 via the exhaust frame 6, multi-port pipe frame 5, and telescopic hose 7. The two filter frames 13 inside the placement box 11 are made of PP material with activated carbon filter layer and alkaline adsorption cotton. They can sequentially intercept particulate matter, adsorb organic gas and neutralize acidic components in the gas. The purified gas is discharged to the external treatment system by the exhaust pump 17. During continuous operation, the support plate 3 securely mounts the fixed shell 2 above the mold stretching mechanism 1 to prevent the exhaust components from shifting due to vibration. The sealing door 10 and handle 12 can be opened quickly to facilitate operators to replace the filter material regularly. After the material completes bidirectional stretching and enters the cooling and shaping stage, the controller 15 controls the electric push rod 4 to drive the exhaust frame 6 to rise and reset. The exhaust pump 17 is delayed and shuts down to ensure that the residual gas is completely purified.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
