Description

Technical Field

[0001] This utility model relates to the field of dyeing and finishing equipment, and in particular to a cold roll-batch continuous production system. Background Technology

[0002] Cold pad-batch dyeing refers to a dyeing process where fabric is immersed in dye liquor and alkali solution at low temperatures. The dye is then applied to the fabric fibers using rollers, followed by rolling and stacking at room temperature for a certain time (bonding time) while being slowly rotated to complete the adsorption, diffusion, and fixation of the dye. Finally, the fabric is washed to complete the dyeing process. This process includes three stages: padding with working solution, padding for color fixation, and washing. The padding and color fixation after padding typically involves rolling approximately 5000 meters of fabric. The following problems are encountered during the cold pad-batch process:

[0003] 1. When washing a roll of fabric, the center part should be piled up first and then washed, while the outer part should be piled up last and washed first. The difference in the time between the inner and outer piles is more than an hour, which will result in different results.

[0004] 2. Cold stacking at room temperature can cause poor capillary effect in the fabric, which seriously affects subsequent processing;

[0005] 3. The joints must be unwound in advance after cold stacking and before water washing, which is labor-intensive;

[0006] 4. Rolling and stacking take up a large area.

[0007] The usual solution to the problem of poor capillary effect in fabrics caused by insufficient temperature during ambient temperature cold stacking is to build a constant temperature cold stacking room. However, constant temperature cold stacking rooms have the problem of high heat energy consumption. To address this, Chinese utility model patent No. 201510034302.5 discloses a cold-pad-batch fiber dyeing device, comprising a dyeing machine, a mobile cold stacking cart, a washing machine, a water-pinching machine, and a dryer arranged sequentially. This cold-pad-batch fiber dyeing device achieves cold stacking color fixation through a mobile cold stacking cart, thus eliminating the need for a cold stacking room and reducing production costs. However, this solution still has technical problems such as large footprint, the need to unwind the splices before washing after cold stacking, and high labor intensity.

[0008] Given the shortcomings of the existing cold packing process, there is an urgent need to innovate the process and develop a continuous cold packing system that has a small footprint and consistent water washing effect. Utility Model Content

[0009] The purpose of this invention is to provide a continuous cold rolling stock production system.

[0010] The technical solution to achieve the purpose of this utility model is: a continuous cold-rolled stock production system, comprising a cold-rolling device, a horizontal transfer device, and a washing device. The horizontal transfer device is located above the cold-rolling device and has a transfer feed end and a transfer discharge end. The cold-rolling device has a cold-rolled discharge end, and the washing device has a washing feed end. The cold-rolling device is located below the transfer feed end, and the washing device is located below the transfer discharge end. A fabric storage box for receiving fabric is placed at the cold-rolled discharge end. A first transfer mechanism for sequentially transferring the fabric storage box to the transfer feed end is installed between the fabric storage box and the transfer feed end. A second transfer mechanism for sequentially transferring each fabric storage box to the washing feed end is installed on the side of the transfer discharge end. A fabric storage box turning station is provided on the side of the washing feed end. A turning table for receiving the fabric in the fabric storage box after it has been turned 180° is installed at the fabric storage box turning station. A fabric guide roller mechanism is installed between the turning table and the washing device.

[0011] Furthermore, a turning device is installed on the turning platform for turning the storage box 180°. The turning device automates the turning process.

[0012] Furthermore, the flipping device includes two horizontally movable positioning posts, each of which is equipped with a clamping assembly. The clamping assembly includes a baffle and a clamping rod. The baffle is rotatably mounted on the positioning post via a rotating mechanism, and the clamping rod is horizontally mounted on the baffle. The two clamping rods are arranged horizontally opposite each other. Hollow positioning handles for aligning the clamping rods are provided on both sides of the fabric storage box.

[0013] Furthermore, both the first transfer mechanism and the second transfer mechanism are electric hoists.

[0014] Furthermore, a heat exchanger for heating the fabric in the storage box on the horizontal transfer device is provided between the washing device and the horizontal transfer device.

[0015] Furthermore, the washing device has a water outlet, which is connected to the heat exchanger pipe. The wastewater heat from the washing device is passed into the heat exchanger to heat the fabric in the storage box on the horizontal transfer device, thereby realizing waste heat utilization and shortening the storage time.

[0016] The advantages of the continuous cold-rolled stock production system implemented by this utility model are as follows:

[0017] 1. The traditional ground-based static cold stacking method has been changed to a three-dimensional mobile stacking method, which reduces the floor space required;

[0018] 2. The rolling and static cold stacking method has been changed to a stacking and cold stacking method. At the same time, a fabric storage box turning station has been added to facilitate the extraction of the bottom layer of fabric in the same fabric storage box before the washing process. This solves the problem of inconsistent results caused by the central part being stacked before washing and the outer ring being stacked later and washed first in the traditional rolling structure, thus ensuring consistent product quality.

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, a continuous cold-rolled stock production system includes a cold-rolling unit 1, a horizontal transfer unit 2, and a washing unit 3. The horizontal transfer unit 2 is located above the cold-rolling unit 1 and has a transfer feed end 21 and a transfer discharge end 22. The cold-rolling unit 1 has a cold-rolled discharge end 11, and the washing unit 3 has a washing feed end 31. The cold-rolling unit 1 is located below the transfer feed end 21, and the washing unit 3 is located below the transfer discharge end 22. A fabric storage box 4 for receiving fabric is placed on the side of the cold-rolled discharge end 11. A first transfer mechanism 5 is installed between the transfer feeding end 21 and the transfer feeding end 21 for sequentially transferring the fabric storage boxes 4 to the transfer feeding end 21. A second transfer mechanism 6 is installed between the transfer discharging end 22 and the transfer feeding end 21 for sequentially transferring each of the fabric storage boxes 4 transported to the transfer feeding end 21 to the washing feeding end side 31. A fabric storage box turning station 10 is provided on the washing feeding end side 31. A turning table 7 is installed on the fabric storage box turning station 10 for receiving the fabric in the fabric storage box 4 after it has been turned 180°. A fabric guide roller mechanism 8 is installed between the turning table 7 and the washing device 3.

[0023] Furthermore, the flipping table 7 is equipped with a flipping device 9 for flipping the storage box 180°. The flipping device 9 includes two horizontally movable positioning posts 91. Each positioning post 91 is equipped with a clamping assembly 92. The clamping assembly 92 includes a baffle 921 and a clamping rod 922. The baffle 921 is rotatably mounted on the positioning post 91 through a rotating mechanism. The clamping rod 922 is horizontally mounted on the baffle 921. The two clamping rods 922 are arranged opposite to each other. Hollow positioning handles 41 for aligning the clamping rods 322 are provided on both sides of the storage box 4.

[0024] Furthermore, a heat exchanger 20 for heating the fabric in the storage box 4 on the horizontal transfer device 2 is provided between the washing device 3 and the horizontal transfer device 2. The washing device 3 has a water outlet (not shown), which is connected to the heat exchanger 20 by a pipe.

[0025] In this embodiment, both the first transfer mechanism 5 and the second transfer mechanism 6 are electric hoists; the positioning column 9 is driven to move relative to each other by the linear slide rail 93, and the clamping assembly 92 is driven to rotate by the worm gear transmission mechanism 94.

[0026] The working principle of the cold rolling stock continuous production system implemented in this embodiment is as follows:

[0027] 1) Cold rolling and liquid application process: The fabric is rolled and liquid-coated in the cold rolling device 1 and then exits the device;

[0028] 2) Jointing process: The fabric storage box 4 is placed below the cold rolling discharge end 12 for stacked fabric discharge. The first end of the fabric to be discharged is the head end 101 of the fabric 100, and the last end of the fabric to be discharged is the end end 102 of the fabric. The head end 101 of the fabric is located at the bottom of the fabric storage box. The fabrics between adjacent fabric storage boxes 4 are manually joined. During the joining process, the end end 102 of the fabric in the first-packed fabric storage box 4 is connected to the head end 101 of the fabric in the last-packed fabric storage box 4 through an acid and alkali resistant guide cloth. The fabrics in the fabric storage box 4 are wrapped with plastic tarpaulin to block the wind.

[0029] 3) Settling process: The first transfer mechanism 5 sequentially hoists and transfers each of the fabric storage boxes 4 to the horizontal transfer device 2 for settling, and uses the heat of the heat exchanger 20 to heat and keep the fabric in the fabric storage boxes on the horizontal transfer device 2 warm.

[0030] 4) Flipping process: Each of the storage boxes 4 is sequentially hoisted and transferred to the storage box flipping station 10 by the second transfer mechanism 6. The two positioning columns 91 of the flipping device 9 approach each other under the drive of the linear slide rail 93 until the clamping rod 922 is inserted into the corresponding positioning handle 41. The baffle 921 is in contact with the side wall of the storage box 4. Then, the worm gear transmission mechanism 94 drives the baffle 921 to rotate 180°, thereby flipping the storage box 4 on the flipping table 7 by 180 degrees. After the storage box 4 is flipped into place, it is manually removed. Among them, the head end 101 of the fabric in the first storage box 4 transferred to the storage box flipping station 10 is pulled out to the fabric guide roller mechanism 8 for threading.

[0031] 5) Washing: The fabric passing through the fabric guide roller mechanism 8 continuously enters the washing device 3 for washing and then exits.

[0032] This invention significantly improves the efficiency of cold-rolled stacking by using a reasonable layout and joint and box-turning processes in the cold-rolled stacking production line.

[0033] In addition to the box-turning device, this utility model can also be used to manually turn the storage box, but mechanical turning is more efficient.

[0034] The horizontal transfer device described in this utility model can be a conventional mechanical transmission structure in the field of machinery, such as a belt drive or chain drive mechanism.

[0035] The structure of the box-flipping device described in this utility model is not limited to the embodiment shown, and can also be other robotic arm structures with clamping and flipping functions in the mechanical field; wherein, the positioning column can be moved linearly by a motor-driven gear rack, or it can be moved by a motor lead screw-nut, which are conventional structures in the mechanical field and not innovations of this utility model, and will not be described in detail here; the rotating mechanism can be a conventional structure in the mechanical field such as gear transmission, worm gear transmission, etc., and will not be described in detail here.

[0036] The first and second transfer mechanisms of this utility model can be electric hoists or other mechanical lifting structures.

[0037] The heat exchanger described in this invention can be configured as needed, and its structure can be either a conventional tubular heat exchanger or a plate heat exchanger. The tubular heat exchanger can pass wastewater heat from the washing device into it, utilizing the temperature within the cloth storage box on the horizontal transfer device to achieve waste heat utilization and shorten storage time.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent process 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.
