Description

Technical Field

[0001] This invention relates to the field of silk production equipment technology, and in particular to a pre-shrinking device for silk fabrics. Background Technology

[0002] Fabric pre-shrinking is a crucial step in the processing of high-end fabrics such as silk, aiming to reduce the shrinkage rate of the fabric during subsequent washing or use through physical or chemical methods. Existing technologies typically employ a process flow of "low-temperature steam humidification—tension stretching—cooling and setting." Among these, the tension stretching stage is critical to the pre-shrinking effect and the fabric's smoothness.

[0003] However, existing tension adjustment mechanisms (such as tension roller one and tension roller two) typically only allow for fixed-position adjustment by sliding the drive component within the guide groove. In actual processing, the physical properties (such as elastic modulus and wet strength) of silk fabric change significantly after humidification, and different batches and materials of silk respond differently to tension. Existing fixed or preset tension adjustment methods cannot respond in real-time and adaptively to the dynamic tension changes of the fabric during processing. This can easily lead to excessive tension causing fabric deformation or tearing, or insufficient tension preventing effective flattening and causing wrinkles, severely affecting the pre-shrinking effect and yield. Summary of the Invention

[0004] The purpose of this invention is to provide a pre-shrinking device for silk fabrics to solve the problems mentioned in the background art.

[0005] The technical solution of the present invention is: a silk fabric pre-shrinking device, comprising a platform, a discharge roller, a humidifying component, a drying component, and a receiving roller arranged sequentially on the platform, and further comprising a tension adjusting component disposed between the humidifying component and the drying component. The tension adjusting component includes a frame symmetrically distributed on the platform, two tension rollers vertically distributed between the frame, elastic support portions disposed at both ends of the tension rollers, an impact portion disposed within the frame, and a control portion for triggering the action of the impact portion according to the movement state of the elastic support portion. When the tension of the silk fabric increases abnormally instantaneously, the two tension rollers approach each other and squeeze the elastic support portion, so that the control portion triggers the action of the impact portion, pushing the tension rollers to reset.

[0006] Furthermore, the elastic support includes a guide groove longitudinally formed on the frame, a slider disposed at the end of the tension roller and slidably engaged with the guide groove, a support plate fixed to one side of the frame, a support rod disposed on the support plate and slidably engaged with the slider, and a first spring sleeved on the support rod and located between the slider and the support plate.

[0007] Furthermore, the impact part includes a cavity formed within the frame and communicating with the guide groove, an impact block and a lower pressure plate that slide in cooperation with the inner wall of the cavity, a central rod connecting the impact block and the lower pressure plate, a second spring disposed between the lower pressure plate and the bottom of the cavity, and a limiting rod disposed at the bottom of the cavity.

[0008] Furthermore, the impact block is provided with a buffer pad at the end near the slider.

[0009] Furthermore, the control unit includes a transverse groove and a longitudinal groove that are perpendicularly connected to each other and formed on the frame, a transverse moving part that cooperates with the transverse groove, a driving part disposed in the longitudinal groove, and a thrusting part for pushing the transverse moving part to control the driving part to release the limiting position of the impact block.

[0010] Furthermore, the transverse moving part includes a transverse moving block slidably connected to the transverse groove, a first inclined surface disposed at one end of the transverse moving block located inside the transverse groove, and a first sphere disposed at one end of the transverse moving block located outside the transverse groove.

[0011] Furthermore, the driving unit includes a lifting block slidably connected to the longitudinal groove, a third spring disposed between the lifting block and the bottom of the longitudinal groove, a second inclined surface disposed at one end of the lifting block located inside the longitudinal groove and slidably engaged with the first inclined surface, and a baffle disposed at one end of the lifting block located outside the longitudinal groove, the baffle being used to limit the impact block.

[0012] Furthermore, the driving unit also includes a longitudinal through groove connecting the cavity and the longitudinal groove, and the baffle and the longitudinal through groove are slidably engaged.

[0013] Furthermore, the thrusting part includes a push rod fixed on the slider and a second ball disposed at the end of the push rod and slidingly engaging with the first ball.

[0014] Furthermore, the diameter of the second sphere is 2-3 times the diameter of the first sphere.

[0015] The beneficial effects of this invention are:

[0016] Compared with existing technologies, this invention, by setting up a tension adjustment component, enables instantaneous buffering and adaptive adjustment of tension when the fabric's wet state changes cause abnormal tension increase. This effectively avoids damage to silk fabrics due to excessive tension, significantly reduces wrinkles and irregular stretching caused by tension fluctuations, and allows the fabric to be flattened and pre-shrinked more evenly and effectively after humidification, thereby improving the flatness and dimensional stability of the final product.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0023] Examples, such as Figures 1-4 As shown, a silk fabric pre-shrinking device includes a platform 1, a discharge roller 2, a humidification component 3, a drying component 4, and a take-up roller 5 sequentially arranged on the platform 1. The humidification component 3 and the drying component 4 in this embodiment are existing technologies and will not be described again. Preferably, the humidification component 3 uses steam humidification, and the drying component 4 uses a fan. The device also includes a tension adjusting component 6 disposed between the humidification component 3 and the drying component 4. The tension adjusting component 6 includes a frame 601 symmetrically distributed on the platform 1 and two components vertically distributed between the frame 601. The tension roller 602, the elastic support portion 603 disposed at both ends of the tension roller 602, the impact portion 604 disposed in the frame 601, and the control portion 605 for triggering the action of the impact portion 604 according to the movement state of the elastic support portion 603 are all included. In this embodiment, the silk fabric is wrapped around the two tension rollers 602 in an S-shape. When the tension of the silk fabric increases abnormally at an instant, the two tension rollers 602 approach each other and squeeze the elastic support portion 603, so that the control portion 605 triggers the action of the impact portion 604 and pushes the tension roller 602 to reset.

[0024] During normal operation, the two tension rollers 602 maintain a preset distance under the action of the elastic support 603, applying stable tension to the humidified silk fabric. When the tension of the fabric increases abnormally due to changes in moisture or other reasons, the fabric will pull the two tension rollers 602 to overcome the elastic force of the elastic support 603 and move closer to each other. This approaching action is sensed by the control unit 605 and serves as a trigger signal to activate the impact unit 604. The impact unit 604 then reverses its action, applying an impact force to the tension rollers 602, forcing them to return to their initial positions, thereby quickly offsetting the excessive tension. Compared with the fixed tension adjustment of the prior art, the present invention can respond to and actively intervene in instantaneous abnormal tension in real time, effectively avoiding deformation or tearing of the silk fabric caused by a sudden increase in tension, and significantly improving the stability of the pre-shrinking process and the quality of the finished product.

[0025] In an optional embodiment of the present invention, the elastic support 603 includes a guide groove 6031 longitudinally formed on the frame 601, a slider 6032 disposed at the end of the tension roller 602 and slidably engaged with the guide groove 6031, a support plate 6033 fixed to one side of the frame 601, a support rod 6034 disposed on the support plate 6033 and slidably engaged with the slider 6032, and a first spring 6035 sleeved on the support rod 6034 and located between the slider 6032 and the support plate 6033. One end of the slider 6032 may be provided with a bearing, and the ends of the tension rollers 602 are rotatably connected to the corresponding sliders 6032 through the bearings, so that the two tension rollers 602 can move up and down and rotate freely. When the tension increases abnormally, the tension roller 602 drives the slider 6032 at its end to move longitudinally along the guide groove 6031 on the frame 601. When the slider 6032 moves, it slides along the support rod 6034 and compresses the first spring 6035 between the support rod and the support plate 6033. After being compressed, the first spring 6035 generates an elastic force in the opposite direction of movement, providing an initial buffer and reset basis for the tension roller 602. The guide groove 6031 and the support rod 6034 together ensure the linearity and smoothness of the slider 6032's movement. By setting an elastic support composed of the guide groove 6031, slider 6032, support rod 6034, and first spring 6035, not only is a precise longitudinal movement guide provided for the tension roller 602, ensuring the stability of its movement trajectory, but the compression energy storage characteristics of the first spring 6035 are also used to achieve the initial absorption and buffering of instantaneous abnormal tension, creating the preconditions for the precise triggering and powerful reset of the subsequent impact part 604.

[0026] In an optional embodiment of the present invention, the impact unit 604 includes a cavity 6041 formed in the frame 601 and communicating with the guide groove 6031, an impact block 6042 and a lower pressure plate 6043 that slide in cooperation with the inner wall of the cavity 6041, a central rod 6044 connecting the impact block 6042 and the lower pressure plate 6043, a second spring 6045 disposed between the lower pressure plate 6043 and the bottom of the cavity 6041, and a limiting rod 6047 disposed at the bottom of the cavity 6041. When the control unit 605 releases the restriction on the impact block 6042, the compressed second spring 6045 quickly releases its elastic potential energy, pushes the lower pressure plate 6043 to move upward, and drives the impact block 6042 to quickly impact the slider 6032 along the inner wall of the cavity 6041 through the central rod 6044, thereby realizing a fast and powerful forced reset action and effectively counteracting the instantaneous high tension generated by the fabric.

[0027] In an optional embodiment of the present invention, the impact block 6042 is provided with a buffer pad 6046 near the slider 6032. When the impact part 604 is triggered, the impact block 6042 impacts the slider 6032 at high speed under the push of the second spring 6045. The buffer pad 6046 at its end will first contact the slider 6032. The buffer pad 6046 absorbs and delays the rigid collision force generated at the moment of impact through its own elastic deformation, making the tension reset process more stable and gentle, and further reducing the risk of secondary damage to the fabric caused by violent impact.

[0028] In an optional embodiment of the present invention, the control unit 605 includes a transverse groove 6051 and a longitudinal groove 6052 formed on the frame 601 and perpendicularly connected to each other, a transverse moving part cooperating with the transverse groove 6051, a driving part disposed in the longitudinal groove 6052, and a thrusting part for pushing the transverse moving part to control the driving part to cancel the limiting of the impact block 6042; the thrusting part is linked with the slider 6032. When the slider 6032 moves, the thrusting part pushes the transverse moving part to move horizontally in the transverse groove 6051, causing the driving part to be displaced in the longitudinal groove 6052, thereby removing the physical limiting of the impact block 6042. Through the precise cooperation of the transverse groove 6051, the longitudinal groove 6052, the transverse moving part, and the driving part, the small displacement of the tension roller 602 is reliably and stably converted into the triggering action of the impact part 604, which has extremely high response speed and reliability, and is very suitable for stable operation in the humid and high-temperature silk pre-shrinking environment.

[0029] In an optional embodiment of the present invention, the lateral movement part includes a lateral movement block 6053 slidably connected to the lateral groove 6051, a first inclined surface 6054 disposed at one end of the lateral movement block 6053 located inside the lateral groove 6051, and a first sphere 6055 disposed at one end of the lateral movement block 6053 located outside the lateral groove 6051. When the thrust part is applied, it pushes the first sphere 6055 at the outer end of the lateral movement block 6053, causing the entire lateral movement block 6053 to slide inward within the lateral groove 6051. When the lateral movement block 6053 slides inward, the first inclined surface 6054 at its end will move accordingly. Through the inclined surface engagement, the horizontal thrust is transmitted and converted into a vertical force on the drive part, thereby driving the drive part to move.

[0030] In an optional embodiment of the present invention, the driving unit includes a lifting block 6056 slidably connected to the longitudinal groove 6052, a third spring 6057 disposed between the lifting block 6056 and the bottom of the longitudinal groove 6052, a second inclined surface 6058 disposed at one end of the lifting block 6056 located inside the longitudinal groove 6052 and slidably engaged with the first inclined surface 6054, and a baffle 6059 disposed at one end of the lifting block 6056 located outside the longitudinal groove 6052. In this embodiment, the baffle 6059 has a magnetic attraction function, the bottom of the impact block 6042 is a magnetically attractable metal, and the baffle 6059 is used to limit the impact block 6042. The baffle 6059 extends horizontally to the bottom of the impact block 6042. Preferably, in this embodiment, the baffle 6059 is symmetrically distributed on both sides of the bottom of the impact block 6042. Under normal conditions... The baffle 6059 magnetically attracts the bottom of the impact block 6042, keeping it in the lower position against the elastic force of the second spring 6045. At this time, the second spring 6045 is in a compressed energy storage state. The baffle 6059 moves towards the bottom of the cavity 6041, causing the impact block 6042 to compress the second spring 6045. When the impact block 6042 contacts the limit rod 6047, the baffle 6059 continues to move towards the bottom of the cavity 6041, separating the baffle 6059 and the impact block 6042. The compressed second spring 6045 releases its stored elastic potential energy, pushing the impact block 6042 to move quickly towards the slider 6032, providing an instantaneous impact force to the slider 6032. This impact force quickly counteracts the excessive tension transmitted from the silk fabric, pushing the slider 6032 and the tension roller to reset.

[0031] In an optional embodiment of the present invention, the drive unit further includes a longitudinal through groove 60510 connecting the cavity 6041 and the longitudinal groove 6052, and a baffle 6059 slidingly engages with the longitudinal through groove 60510; the baffle 6059 extends into the cavity 6041 through the longitudinal through groove 60510 to block the impact block 6042. Simultaneously, the sliding engagement between the baffle 6059 and the longitudinal through groove 60510 provides precise guidance for the up-and-down movement of the lifting block 6056, ensuring not only that the baffle 6059 can reliably extend into the cavity 6041 to perform the limiting function, but also that the sliding engagement constrains and guides the movement of the baffle 6059, guaranteeing its positional accuracy and smooth movement during frequent actions, thereby improving the reliability of the entire triggering mechanism.

[0032] In an optional embodiment of the present invention, the thrusting part includes a push rod 60511 fixed on the slider 6032 and a second ball 60512 disposed at the end of the push rod 60511 and slidingly engaged with the first ball 6055. The diameter of the second ball 60512 is 2-3 times the diameter of the first ball 6055. When the slider 6032 moves due to abnormal tension, the push rod 60511 fixed on it moves accordingly. The second ball 60512 at the end of the push rod 60511 contacts and pushes the first ball 6055 of the transverse part. Since the surfaces of the first ball 6055 and the second ball 60512 are both curved, they can achieve low-friction point contact or line contact, thereby smoothly and efficiently transmitting the displacement of the slider 6032 to the transverse block 6053.
