Description

Technical Field

[0001] This utility model relates to the field of steaming machine technology, and in particular to an intelligent steaming machine main chain tension control device. Background Technology

[0002] Intelligent steaming machines are key equipment in the printing and dyeing industry, used for heat treatment such as color fixing and color development of dyed or printed fabrics. Internally, they typically use a ring chain system to transport the fabric, which is evenly suspended by hanging rollers and passes through a high-temperature steam environment at a constant speed. To ensure process stability and fabric quality, the conveyor chain must maintain a constant tension.

[0003] Currently, the mainstream chain tensioning device in the industry is the pneumatic tensioning system. The core of this system uses a cylinder. Compressed air is adjusted to a constant pressure via a pressure reducing valve and then fed into the cylinder to move a slide block equipped with a tensioning sprocket, thus tensioning the entire chain system. Pneumatic tensioning devices are simple in structure, low in cost, and easy to implement, but they have the following drawbacks:

[0004] If the cylinder leaks, the pressure inside the cylinder will be lost instantly, and the cylinder piston rod will retract rapidly under the action of the chain contraction force, causing the tension sprocket to lose its restraint on the chain instantly, and the entire chain will become completely loose.

[0005] When the chain loosens, its total length path becomes shorter, causing an uncontrollable shift in the relative positions of all the fabric rollers meshing with the chain, resulting in misalignment of the fabric rollers.

[0006] Since steaming machines typically use multiple chains to synchronously drive a set of fabric hanging rollers, if one chain loosens and then straightens, the position of the fabric hanging roller at that point will be out of sync with the positions of the rollers on the other chains. During operation, this will cause uneven force on both ends of the fabric hanging roller, generating torque. This can accelerate the wear of the chains and sprockets, or even cause the chains to skip teeth, jam, and interrupt production.

[0007] Misaligned fabric rollers can disrupt the uniform distribution and tension of the fabric within the equipment, easily causing quality problems such as fabric deviation, wrinkling, and scratching, resulting in a large number of defective fabrics and economic losses. Utility Model Content

[0008] The main technical problem solved by this utility model is to provide an intelligent steaming machine main chain tension control device, which can provide a continuous and stable tension force through elastic elements and can be accurately controlled. Even if slight deformation occurs, the tension force will not change abruptly, ensuring that the chain is always taut, effectively avoiding problems such as fabric deviation and wrinkling, and improving the printing and dyeing quality.

[0009] To solve the above-mentioned technical problems, the present invention provides a technical solution: a smart steaming machine main chain tension control device, comprising:

[0010] Elastic elements are used to provide tension force;

[0011] The swing arm transmission assembly includes a wall plate shaft, a first swing arm, a second swing arm, and a third swing arm. The first and second swing arms are respectively connected to both ends of the wall plate shaft.

[0012] The tensioning actuator includes a sliding plate slidably mounted on the wall panel of the steamer and a passive sprocket mounted on the sliding plate. The passive sprocket is configured to mesh with the main chain, and the sliding plate is connected to the other end of the third swing arm.

[0013] The tension force provided by the elastic element is transmitted through the swing arm transmission assembly and acts on the tensioning execution assembly, so that the passive sprocket tensions the main chain.

[0015] In a preferred embodiment of this utility model, the wall panel is provided with a slide rail, and the slide plate slides in cooperation with the slide rail.

[0018] In a preferred embodiment of this utility model, a tension adjustment mechanism is further included, which includes an adjusting screw and a screw adjusting seat disposed on the wall panel. The adjusting screw is connected to the screw adjusting seat, and its end is connected to an elastic element.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 3 This utility model relates to a preferred embodiment of an intelligent steaming machine main chain tension control device, which aims to achieve stable tension and adjustment of the steaming machine main chain.

[0033] The device is symmetrically installed on the wall panels on both sides of the steaming machine. Through synchronous operation on both sides, it ensures that the main chain is subjected to uniform force and smooth transmission, and avoids uncontrollable displacement of the hanging roller that meshes with the main chain, thus ensuring the high efficiency and stability of the equipment operation.

[0034] The intelligent steaming machine main chain tension control device includes an elastic element 1 that provides tension force, a swing arm transmission assembly for power transmission, and a tensioning execution assembly. The tension force provided by the elastic element 1 is transmitted through the swing arm transmission assembly and acts on the tensioning execution assembly, driving the passive sprocket 2 to tension the main chain.

[0035] Specifically, the elastic element 1 is used to provide a continuous and stable tension force, which needs to meet the working load requirements of the main chain of the steaming machine. In this embodiment, the elastic element 1 can be a compression spring, a tension spring, or a spring. These elastic elements have good elasticity and stability, and can adjust the tension force according to the load changes of the main chain to ensure that the main chain always maintains an appropriate tension.

[0036] The swing arm transmission assembly is used to transmit the tensioning force of the elastic element 1 to the tensioning actuator assembly, and includes a wall plate shaft 3, a first swing arm 4, a second swing arm 5, and a third swing arm 6. The wall plate shaft 3 passes through the wall plate, with one end of the wall plate shaft 3 placed inside the housing and the other end placed outside the housing.

[0037] The through-wall plate shafts 3 on both sides rotate synchronously through couplings, thereby ensuring that the swing arm transmission components on both sides move synchronously, avoiding the main chain from tilting due to unilateral force, and ensuring the smooth transmission of the main chain.

[0038] The first swing arm 4 and the second swing arm 5 are respectively connected to the two ends of the through-wall plate shaft 3. The other end of the first swing arm 4 relative to the through-wall plate shaft 3 is connected to the elastic element 1. The other end of the second swing arm 5 relative to the through-wall plate shaft 3 is hinged to the third swing arm 6 through the pin 8.

[0039] When the elastic element 1 generates tension force, the tension force is transmitted to the through-wall plate shaft 3 through the first swing arm 4, and then the through-wall plate shaft 3 drives the second swing arm 5 and the third swing arm 6 to move, thereby transmitting the tension force to the tensioning actuator.

[0040] The tensioning actuator is used to achieve tensioning by engaging the passive sprocket 2 with the main chain. It includes a slide plate 9 slidably mounted on the wall plate of the steamer and a passive sprocket 2 mounted on the slide plate 9. The slide plate 9 is connected to the other end of the third swing arm 6. The passive sprocket 2 is configured to engage with the main chain.

[0041] Furthermore, the wall panel of the steamer is provided with a slide rail 10, and the slide plate 9 slides in cooperation with the slide rail 10. The extension direction of the slide rail 10 is set so that the sliding of the slide plate 9 can adjust the center distance between the passive sprocket 2 and the main chain drive sprocket.

[0042] The slide plate 9 is also connected to a bearing seat 7. The passive sprocket 2 is supported on the bearing seat 7 by the bearing, which ensures that the passive sprocket 2 is installed stably and reliably and reduces friction loss during operation.

[0043] Based on the above structure, this device is also provided with a tension adjustment mechanism for adjusting the compression of the elastic element 1, thereby controlling the tension magnitude. It includes an adjusting screw 11, a screw adjusting seat 12 on the wall plate, and a locking nut 13 for adjusting and locking the position of the adjusting screw 11.

[0044] Furthermore, the adjusting screw 11 is connected to the adjusting screw seat 12, and its end is connected to the elastic element 1. By rotating the adjusting screw 11, the compression of the elastic element 1 can be adjusted, thereby precisely adjusting the tension force. The adjusting position is locked by the locking nut 13 to ensure that the tension force is stable and reliable during operation.

[0045] The working process of the intelligent steaming machine main chain tension control device of this utility model is as follows:

[0046] The elastic element 1 generates elastic force after being compressed by the adjusting screw 11. This elastic force is transmitted to the through-wall plate shaft 3 through the first swing arm 4. The rotation of the through-wall plate shaft 3 synchronously drives the second swing arm 5 to swing. The second swing arm 5 then drives the third swing arm 6 to move. The end of the third swing arm 6 away from the second swing arm 5 is hinged to the slide plate 9, thereby pushing the slide plate 9 to slide along the slide rail 10.

[0047] When the slide plate 9 slides along the slide rail 10, it drives the passive sprocket 2 to move synchronously. Since the extension direction of the slide rail 10 is consistent with the center line connecting the main chain drive sprocket and the passive sprocket 2, the passive sprocket 2 changes the center distance between itself and the drive sprocket during its movement, thereby tightening the main chain and achieving the effect of tensioning the main chain.

[0048] When it is necessary to adjust the tension force, loosen the locking nut 13, rotate the adjusting screw 11, and the adjusting screw 11 moves axially under the action of the internal thread of the screw adjusting seat 12, thereby changing the compression of the elastic element 1 (the tension force increases when the compression increases, and the tension force decreases when the compression decreases). After adjusting to the target tension force, tighten the locking nut 13 to lock the position of the adjusting screw 11, and the tension force adjustment is completed.

[0049] The beneficial effects of this intelligent steaming machine main chain tension control device are:

[0050] Its compact structure facilitates installation and maintenance, thereby improving the reliability and service life of the device.

[0051] The elastic element provides a continuous and stable tension force, and the tension force can be precisely controlled. Even if the elastic element is slightly deformed or fatigued, the tension force will not be lost instantly, ensuring that the main chain always maintains an appropriate tension and avoiding chain slack caused by the sudden loss of tension force.

[0052] Stable tension and precise transmission control prevent problems such as fabric deviation, wrinkling, and scratching during operation, thereby significantly improving the dyeing quality of the fabric and reducing the occurrence of fabric defects.

[0053] The main chain is evenly stressed on both sides, avoiding chain skewing and misalignment of the fabric roller caused by unilateral stress. This reduces impact and wear between the chain and sprocket, extends equipment lifespan, lowers maintenance costs, and improves production efficiency.

[0054] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
