Description

Technical Field

[0001] This utility model relates to the technical field of garment fabric processing equipment, and in particular to a multifunctional fabric pre-shrinking and shaping machine. Background Technology

[0002] Fabric pre-shrinking and setting machines are key equipment in the textile finishing industry. Their main function is to eliminate potential stress within the fabric through physical means, improve the fabric's dimensional stability, and enhance its feel and appearance to meet the requirements of subsequent cutting, sewing, and final use. Conventional fabric pre-shrinking and setting machines typically employ a structure that combines heated pressure rollers with an elastic rubber blanket. The fabric passes through the compression zone between the two, shrinking and setting during the elastic deformation and recovery process of the rubber blanket.

[0003] During operation, the rubber blanket must withstand immense pressure, high temperatures, and continuous friction with the fabric, making it a typical consumable component whose performance directly determines the final pre-shrinking quality. When the rubber blanket wears down or its performance deteriorates to a certain extent, it must be replaced to ensure the pre-shrinking effect. However, existing pre-shrinking and setting machines often prioritize their core processing functions, neglecting the replacement process for the rubber blanket. Their installation structures are typically complex, with cumbersome disassembly and installation processes, requiring significant manpower and resources, resulting in excessive downtime and directly impacting production efficiency. Furthermore, under prolonged high-load operation, the rubber blanket's elasticity gradually fatigues, potentially leading to uneven tension distribution or a decrease in overall tension. This unstable working state directly affects the contact pressure and friction between the rubber blanket and the fabric, resulting in inconsistent pre-shrinking effects and impacting the quality of the final product. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-functional fabric pre-shrinking and setting machine, which aims to improve the problems of complex rubber blanket replacement structure, inconvenient and time-consuming disassembly and assembly, and low reliability of pre-shrinking effect caused by unstable working tension of rubber blanket in multi-functional fabric pre-shrinking and setting machines. This utility model aims to provide a multi-functional fabric pre-shrinking and setting machine with an improved structure that can effectively solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional fabric pre-shrinking and shaping machine, comprising: a machine body, a pressure roller and a rubber blanket; as well as a mounting bracket, an auxiliary support mechanism and a quick-change mechanism.

[0006] The mounting bracket is fixed to the machine body.

[0007] Furthermore, both the auxiliary support mechanism and the quick-change mechanism are mounted on the mounting bracket. The auxiliary support mechanism provides elastic support for the rubber blanket, and the quick-change mechanism includes a connecting shaft that is pluggably mounted on the mounting bracket, a protruding handle for driving, and an elastic retaining ring driven by the protruding handle to unlockably fix the connecting shaft.

[0008] Preferably, the auxiliary support mechanism includes an annular support frame and an arc-shaped elastic pressure strip, the annular support frame surrounding and supporting the rubber blanket, and the arc-shaped elastic pressure strip abutting against the inner surface of the rubber blanket to apply elastic pressure.

[0009] Preferably, the auxiliary support mechanism further includes a roller, a support column, and a spring. The support column is connected to the arc-shaped elastic pressure strip, and the spring is sleeved on the support column and abuts against the roller to provide elastic force to the arc-shaped elastic pressure strip through the support column.

[0010] Preferably, the quick-change mechanism further includes a mounting base and a rotating shaft, the rotating shaft being rotatably mounted on the mounting base, and the protruding handle and the elastic retaining ring being fixedly connected to the rotating shaft.

[0011] Preferably, the quick-change mechanism further includes an arc-shaped support base, which supports the connecting shaft, and the elastic retaining ring, in the locked position, together with the arc-shaped support base, limits the connection shaft.

[0012] Preferably, the elastic retaining ring rotates to engage or disengage with a preset locking part on the connecting shaft, thereby locking or unlocking the connecting shaft.

[0013] Preferably, the multifunctional fabric pre-shrinking and shaping machine further includes a fixing ring frame, which is located at the fabric inlet of the machine body and is used to guide and initially flatten the fabric.

[0014] Preferably, the multifunctional fabric pre-shrinking and shaping machine further includes a control mechanism, which includes a control panel disposed on the mounting bracket for setting the machine's operating parameters.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting a quick-change mechanism, the mechanism drives the elastic retaining ring through the protruding handle to realize the quick locking and unlocking of the connecting shaft carrying the rubber blanket. This solves the problems of complicated rubber blanket replacement process, time-consuming disassembly and assembly, and serious impact on production efficiency in the prior art. It achieves the effects of simplifying replacement operation, shortening equipment maintenance downtime, and significantly improving work efficiency.

This utility model, by setting an auxiliary support mechanism, which combines springs, support columns and arc-shaped elastic pressure strips, applies continuous and uniform elastic support to the rubber blanket, solves the problem in the prior art where the rubber blanket deforms or suffers elastic fatigue due to long-term use, resulting in uneven tension and affecting the stability of the fabric pre-shrinking effect. It achieves the effect of ensuring constant working tension of the rubber blanket, thereby improving the quality and consistency of the fabric pre-shrinking and shaping process.

[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] Please refer to Figures 1 to 4 This utility model provides a multifunctional fabric pre-shrinking and shaping machine, which aims to solve the problems of complex and time-consuming rubber blanket replacement process and unstable working tension affecting the pre-shrinking effect in the prior art.

[0026] like Figure 1As shown, the multi-functional fabric pre-shrinking and setting machine includes a machine body 3, a pressure roller 2 mounted on the machine body 3, a fixing ring 4 for guiding the fabric at the fabric inlet of the machine body 3, and a rubber blanket 501 that works in conjunction with the pressure roller 2. The multi-functional fabric pre-shrinking and setting machine also includes a mounting bracket 101 fixed to the machine body 3. The mounting bracket 101 integrates an auxiliary support mechanism 5 that provides elastic support for the rubber blanket 501 and a quick-change mechanism 6 for quickly changing the rubber blanket 501. A control mechanism 1 containing a control panel 102 is also fixedly connected to the mounting bracket 101.

[0027] Please refer to the following carefully. Figure 2 , Figure 3 and Figure 4 The quick-change mechanism 6 includes a mounting base 606 fixedly connected to the mounting bracket 101. A rotating shaft 605 is rotatably connected to the mounting base 606. A protruding handle 601 and an elastic retaining ring 602 are both fixedly connected to the rotating shaft 605, enabling synchronous rotation. The mounting base 606 also has an arc-shaped support 604 for supporting the connecting shaft 603. The connecting shaft 603 is pluggably installed in a slot inside the mounting bracket 101. In the locked state, the elastic retaining ring 602... 2. Together with the arc-shaped support base 604, it forms a limiting and fixing mechanism for the connecting shaft 603 to prevent it from shaking. When the rubber blanket 501 needs to be replaced, the protruding handle 601 is operated to drive the rotating shaft 605 and the elastic retaining ring 602 to rotate, so that the elastic retaining ring 602 disengages from the preset locking part of the connecting shaft 603, thereby releasing the locking of the connecting shaft 603 and allowing the connecting shaft 603 to be quickly pulled out of the slot of the mounting bracket 101. This structure realizes the quick disassembly and assembly of the core components.

[0028] The auxiliary support mechanism 5 is used to provide continuous and uniform tension to the rubber blanket 501. The auxiliary support mechanism 5 includes an annular support frame 503 that surrounds and supports the rubber blanket 501, and an arc-shaped elastic pressure strip 502 that abuts against the inner surface of the rubber blanket 501. The arc-shaped elastic pressure strip 502 is supported by multiple support columns 505. Each support column 505 is fitted with a spring 504. The spring 504 and the support column 505 are both located outside the roller 506. The spring 504 is in a compressed state, and its elastic force is continuously applied to the arc-shaped elastic pressure strip 502 through the support column 505, thereby enabling the arc-shaped elastic pressure strip 502 to apply stable elastic pressure to the rubber blanket 501. This structure can effectively prevent the rubber blanket 501 from affecting the pre-shrinking effect due to its own deformation. At the same time, the design of the annular support frame 503 also helps to position and install the rubber blanket 501 during replacement.

[0029] In a preferred embodiment, please refer to Figure 4The arc-shaped elastic pressure strip 502 in the auxiliary support mechanism 5 is used to apply elastic force evenly to the rubber blanket 501. One end of the support column 505 is fixedly connected to the arc-shaped elastic pressure strip 502 to transmit elastic force, and the other end passes through the roller 506. The spring 504 is sleeved on the rod of the support column 505 located outside the roller 506. One end of the spring 504 abuts against the outer wall of the roller 506, and the other end abuts against the end of the support column 505 to provide continuous elastic potential energy.

[0030] In another preferred embodiment, please refer to Figure 2 and Figure 3 The mounting base 606 in the quick-change mechanism 6 is fixedly connected to the mounting bracket 101 by welding or bolts, providing a stable mounting platform for the rotating parts. The two ends of the rotating shaft 605 are respectively accommodated in the bearing holes of the mounting base 606 to achieve a rotatable connection. The protruding handle 601 is fixed to one end of the rotating shaft 605 to facilitate manual operation to apply torque. The elastic retaining ring 602 is fixed in the middle of the rotating shaft 605, and its shape is adapted to the preset locking part on the connecting shaft 603 to perform locking and unlocking actions. The arc-shaped support 604 is fixed on the mounting base 606, and its concave arc surface is used to support the cylindrical outer surface of the connecting shaft 603 to provide radial support.

[0031] Specifically, the elastic retaining ring 602 can selectively engage or disengage from a preset locking part on the connecting shaft 603 by rotating about the axis of the rotating shaft 605. The preset locking part can be a groove or a flat cutting structure on the connecting shaft 603 to provide reliable engagement positioning.

[0032] As a specific embodiment, the fixed ring frame 4 is set at the feed end of the machine body 3 to perform preliminary flattening and guiding of the fabric, ensuring that the fabric can smoothly enter the pre-shrinking area between the pressure roller 2 and the rubber blanket 501.

[0033] Similarly, the control panel 102 in the control mechanism 1 is fixedly installed on the upper part of the mounting bracket 101 by bolts or snap-fit, and is used by the operator to set process parameters such as the machine's running speed, the temperature and pressure of the pressure roller 2. For the electrical connection between the control panel 102 and the internal motor, heating element and other actuators, those skilled in the art can use a variety of conventional methods such as a programmable logic controller (PLC). The specific circuit design is a well-known technology in the field and will not be described in detail here.

[0034] Working Principle: During pre-shrinking and shaping, the equipment is started via the control panel 102 of the control mechanism 1. The fabric is smoothly fed into the machine body 3 through the fixed ring frame 4. During the process, the fabric passes through the gap area between the rubber blanket 501 and the pressure roller 2. At this time, the spring 504 in the auxiliary support mechanism 5 continuously pushes the arc-shaped elastic pressure strip 502 through the support column 505, so that the arc-shaped elastic pressure strip 502 applies stable and uniform radial pressure to the rubber blanket 501, ensuring that the rubber blanket 501 maintains the preset tension state throughout the entire working width, thereby ensuring... The fabric and the pressure roller 2 achieve a consistent pre-shrinking effect. When the worn rubber blanket 501 needs to be replaced, the operator pushes the protruding handle 601 of the quick-change mechanism 6. The protruding handle 601 drives the rotating shaft 605 and the elastic retaining ring 602 fixed thereon to rotate synchronously. The rotation of the elastic retaining ring 602 causes it to disengage from the locking part on the connecting shaft 603, thereby releasing the lock on the connecting shaft 603. At this time, the connecting shaft 603 and the rubber blanket 501 it carries can be easily pulled out from the slot of the mounting bracket 101 for replacement.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
