Description

Technical Field

[0001] This invention relates to the field of textile dyeing equipment technology, and more particularly to dyeing machines for fabric textiles. Background Technology

[0002] The core process of textile dyeing involves immersing textiles (fibers, yarns, fabrics, etc.) in an aqueous solution or organic liquid medium containing dyes and auxiliaries. By controlling process parameters such as temperature, pH, and time, dye molecules adhere uniformly to and bind to the fibers through adsorption, diffusion, and fixation, ultimately giving the textiles a specific color. The entire process relies on the liquid as both the dye carrier and the reaction medium, falling entirely within the category of liquid-phase processing—"using liquid media to process textiles."

[0003] The dyeing process of textile fabrics is a key step in the textile production process, directly affecting the appearance quality and market value of the products. The dyeing process of textile fabrics needs to be implemented on textile fabric dyeing equipment. Most of the current dyeing equipment cannot meet the processing requirements of gradient dyeing. Therefore, it is necessary to design a penetration dyeing equipment that can be used to perform gradient dyeing on textile fabrics.

[0004] Existing equipment for gradient dyeing requires a fabric hanger to slide back and forth while simultaneously sliding up and down. This causes the fabric, clamped and suspended below the hanger, to move up and down and back and forth in the dye, resulting in the fabric near the top layer of the dye liquid frequently entering and exiting the dye and being dragged back and forth along that top layer, creating a gradient dyeing effect and achieving the dyeing of the fabric. However, the up-and-down and back-and-forth sliding operations of the fabric hanger require separate drive units, and a single drive unit cannot be used. This results in the dyeing equipment needing to be equipped with additional drive units, which is not conducive to reducing the cost and power consumption of the dyeing equipment. Summary of the Invention

[0005] In view of this, the present invention provides a dyeing machine for fabric textiles to solve the problem that the up-and-down and back-and-forth sliding operations of fabric hangers require separate drive units for execution and cannot share a single drive unit.

[0006] The technical solution proposed in this invention is as follows: a dyeing machine for fabric textiles, specifically including a dyeing box and a rectangular holding frame, wherein the rectangular holding frame is fitted into the top part of the dyeing box; two horizontal guide shafts are symmetrically welded on the rectangular holding frame, and two longitudinally spaced slide plates are slidably installed on the two horizontal guide shafts; a fabric hanger is slidably arranged inside the rectangular holding frame, and two U-shaped guide frames are symmetrically welded on the top side of the fabric hanger, with the longitudinally placed slide plates slidingly engaged with the U-shaped guide frames by spring push; a rectangular drive frame is slidably arranged below the fabric hanger, the rectangular drive frame is inserted into the dyeing box, and the two short side shafts of the rectangular drive frame abut against the two short side walls of the dyeing box; a pull rod is symmetrically rotatably connected between the rectangular drive frame and the fabric hanger; a drive assembly is fixedly installed on the rectangular holding frame, and a rotating wheel is fixedly mounted on the power output shaft of the drive assembly, with a connecting rod rotatably connected between the rotating wheel and the corresponding longitudinally placed slide plate.

[0007] Furthermore, a short drive shaft is fixedly connected to the top of the wheel rim, and the two ends of the connecting rod are rotatably connected to the middle part of the longitudinally placed slide plate and the short drive shaft, respectively.

[0008] Furthermore, the spring that pushes the U-shaped guide frame is fitted onto the two vertical guide shafts of the U-shaped guide frame and is compressed and clamped between the longitudinal slide plate and the top side shaft of the U-shaped guide frame.

[0009] Furthermore, the bottom of the fabric hanger is symmetrically welded with four vertical support rods, and the rectangular drive frame slides through and engages with the bottom ends of the four vertical support rods.

[0010] Furthermore, a row of equally spaced longitudinally placed force-bearing plates is fixedly connected inside the fabric hanger, and a row of equally spaced threaded push shafts is rotatably installed at the top of the fabric hanger. Two spaced threaded sleeves are screwed onto the threaded push shafts. A longitudinal clamping plate is slidably installed between each pair of adjacent longitudinal load-bearing plates. A short connecting rod is rotatably connected between the threaded sleeve and the longitudinal clamping plate. The top end of the fabric to be dyed is clamped and positioned between the longitudinal clamping plate and the longitudinal load-bearing plate.

[0011] Furthermore, the inner sides of the two long side rods of the fabric hanger are symmetrically provided with two short sliding grooves located between two adjacent longitudinally placed force plates. The two ends of the longitudinally placed clamping plate are integrally formed with two sliders, which slide in cooperation with the two short sliding grooves.

[0012] Furthermore, a lifting ring is welded to the top of the middle section of the transverse guide shaft.

[0013] Furthermore, two L-shaped clamping plates are symmetrically fixed to the middle position of the outer side of the two long side walls of the dyeing box, and two symmetrically distributed tightening bolts are screwed through the vertical part of the L-shaped clamping plates. A slot is formed between the L-shaped card plate and the long side wall of the dyeing box. The long side plate of the rectangular drive frame is inserted into the slot and supported on the top of the horizontal part of the L-shaped card plate. The first end of the tightening bolt is pressed against the long side plate of the rectangular drive frame.

[0014] The dyeing machine for fabric textiles provided by this invention has the following beneficial effects: 1. Under the combined transmission of the single crank slider mechanism and the multi-crank slider mechanism, the drive assembly can drive the fabric hanger to slide horizontally and vertically at the same time. When the fabric hanger is driven to slide horizontally and vertically at the same time, it can drive the part of the fabric near the top layer of dye liquid to frequently enter and exit the dye and be dragged back and forth along the top layer of liquid, presenting a gradient dyeing effect and realizing the dyeing of the fabric.

[0015] Second, through the combined transmission of single-crank slider mechanism and multi-crank slider mechanism, the up-and-down and back-and-forth reciprocating sliding operations of the fabric hanger can be driven by a single drive unit. Compared with the existing technology, this eliminates the need to configure separate drive units for the above two sliding operations, which helps to reduce the number of drive assemblies required by the dyeing equipment and is conducive to reducing the cost and power consumption of the dyeing equipment.

[0016] 3. The L-shaped clamping plate, through its horizontal portion, can support, block, and limit the rectangular retaining frame, preventing it from sliding down the side wall of the dyeing box and keeping it in a position where it is fitted into the top part of the dyeing box. The tightening bolts can tighten and fix the rectangular retaining frame in the groove between the L-shaped clamping plate and the side wall of the dyeing box, so that the rectangular retaining frame is stably fixed in the assembly state fitted onto the top part of the rectangular retaining frame. This avoids the rectangular retaining frame and the track retaining frame lacking necessary positioning, which would cause necessary jerking or unreasonable vibration under the driving stress of the drive assembly driving the fabric hanger, affecting the stability of the sliding operation of the fabric hanger.

[0026] Preferably, a row of equally spaced longitudinally placed force-bearing plates 403 are fixedly connected inside the fabric hanger 4. A row of equally spaced threaded push shafts 402 are rotatably installed at the top of the fabric hanger 4. Two threaded sleeves 4021 are threaded and screwed onto the threaded push shafts 402.

A groove is formed between the L-shaped clamping plate 102 and the long side wall of the dyeing box 1. The long side plate of the rectangular drive frame 5 is inserted into the groove and supported on the top of the horizontal part of the L-shaped clamping plate 102. The head end of the tightening bolt 1021 is pressed against and in contact with the long side plate of the rectangular drive frame 5.

[0030] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: The rectangular retaining frame 3 and the two horizontal guide shafts 301 together form a track retaining frame for installing the fabric hanger 4 and for the fabric hanger 4 to slide. The track retaining frame is hoisted and transferred by an external hoisting device and is fitted into or removed from the dyeing box 1. The hook of the wire rope on the hoisting device is hooked and connected to the lifting ring 3011. The hoisting device uses the wire rope to lift the two horizontal guide shafts 301 to transfer and disassemble the track retaining frame. Initially, the track retainer is located on one side of the dyeing box 1 and is in a suspended state, detached from the dyeing box 1. In use, multiple pieces of fabric are first clamped and suspended onto the fabric hanger 4 using longitudinal clamping plates 404. Then, the track retainer, fabric hanger 4, and the fabric clamped and fixed to the fabric hanger 4 are transferred to above the dyeing box 1 using hoisting equipment. The track retainer is then lowered, and the rectangular retaining frame 3 is aligned with the dyeing box 1. The track retainer is then fitted onto the top part of the rectangular retaining frame 3. The rectangular retaining frame 3 and the dyeing box 1 are then fitted together. When the rectangular retaining frame 3 is fitted onto the dyeing box 1, the fabric hanger... The frame 4, rectangular drive frame 5, and the fabric hanging below the fabric hanger 4 are all placed in the dyeing box 1. The fabric falls into the dyeing box 1 and is immersed in the dye for penetration dyeing. The two short side shafts of the rectangular drive frame 5 are in contact with the two short side walls of the dyeing box 1. Then, the drive assembly 2 is started. After the drive assembly 2 is started, the drive wheel 201 rotates. The drive wheel 201, the short transmission shaft 2011, the connecting rod 3021, and the longitudinal sliding plate 302 are connected to form a single crank slider mechanism. Through this mechanism, the drive assembly 2 can drive the two longitudinal sliding plates 302 and the two... The U-shaped guide frame 401 and the fabric hanger 4 slide back and forth laterally. The pull rod 501, the rectangular drive frame 5, and the fabric hanger 4 together form a multi-crank slider mechanism. Since the rectangular drive frame 5 is blocked and limited by the two short side walls of the dyeing box 1, it can be seen from the operating principle of the multi-crank slider mechanism that when the fabric hanger 4 is driven to slide back and forth laterally, it can be driven to slide up and down by the downward pulling reaction force transmitted from the rectangular drive frame 5 in the static limited state to the pull rod 501. Thus, under the combined transmission of the single-crank slider mechanism and the multi-crank slider mechanism, the drive assembly 2 can drive the fabric hanger 4 to slide back and forth laterally. Simultaneously, the fabric hanger 4 is driven to slide horizontally and vertically, causing the part of the fabric near the top layer of dye liquid to frequently enter and exit the dye and be dragged back and forth along the top layer of liquid, presenting a gradient dyeing effect and achieving the dyeing of the fabric. After the gradient dyeing of the fabric is completed through the multi-dimensional reciprocating sliding action of the fabric hanger 4, the transfer track retainer is lifted by the hoisting equipment, and the dyed fabric is transferred out of the dyeing box 1 for disassembly. After the dyed fabric is disassembled and removed, it is transferred to the subsequent processing steps for further processing. At this point, the gradient dyeing process of the fabric is completed.

[0031] A discharge pipe 101 with a built-in valve is welded to the middle of the bottom side of one long side wall of the dyeing box 1. The discharge pipe 101 can be used to drain and replace dyes that have become ineffective after long-term use.

[0032] Through the combined transmission of the single-crank slider mechanism and the multi-crank slider mechanism, the up-and-down and back-and-forth reciprocating sliding operations of the fabric hanger 4 can be driven by a single drive unit. Compared with the existing technology, this eliminates the need to configure separate drive units for the two sliding operations, which helps to reduce the number of drive assemblies 2 required by the dyeing equipment, and also helps to reduce the cost and power consumption of the dyeing equipment.

[0033] The L-shaped clamping plate 102 can support and limit the rectangular retaining frame 3 through its horizontal portion, preventing the rectangular retaining frame 3 from sliding down the side wall of the dyeing box 1, and keeping the rectangular retaining frame 3 in a state of fitting with the top part of the dyeing box 1; the tightening bolt 1021 can tighten and fix the rectangular retaining frame 3 in the groove between the L-shaped clamping plate 102 and the side wall of the dyeing box 1, so that the rectangular retaining frame 3 is stably fixed in the assembly state fitted on the top part of the rectangular retaining frame 3, and avoids the rectangular retaining frame 3 and the track retaining frame lacking necessary positioning, which would cause necessary jerking or unreasonable vibration under the driving stress of the drive assembly 2 driving the fabric hanger 4, affecting the stability of the sliding operation of the fabric hanger 4.

[0034] The two threaded sleeves 4021, the two short connecting rods 4022, and the longitudinal clamping plate 404 together form a crank-slide mechanism. Through this mechanism, the forward and reverse rotation of the threaded drive shaft 402 can drive the two threaded sleeves 4021 to slide back and forth along the longitudinal direction, and drive and control the longitudinal clamping plate 404 to slide away from or near the longitudinal force plate 403, thereby adjusting the tension of the fabric.

[0035] Springs on the two U-shaped guide frames 401 can push and limit the fabric hanger 4 to a state of contact with the two longitudinally placed sliding plates 302 (see reference). Figure 3 To avoid the lack of necessary sliding limits for the fabric hanger 4, during the process of sliding down to assemble the track retainer, the fabric hanger 4 is driven up and down by the inertial force of the pause when following the lifting equipment. This is driven by the pull rod 501 to control the rectangular drive frame 5 to slide back and forth laterally, and cannot be stably kept in the static limit state. This causes the rectangular drive frame 5 to not be centered, and the two short side shafts of the rectangular drive frame 5 may slide out of place and come into contact with the top of the two short side walls of the dyeing box 1. This will obstruct and interfere with the descent assembly of the track retainer and the rectangular retainer 3, affecting the normal and smooth assembly of the track retainer and the rectangular retainer 3. The following points should be noted in this article: 1. The accompanying drawings of the embodiments of the present invention only involve the structures involved in the embodiments of the present invention; other structures can refer to general designs.

[0036] 2. Where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other to obtain new embodiments.

[0037] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
