Description

Technical Field

[0001] This utility model relates to the field of dyeing and finishing equipment, and in particular to a fabric dyeing and baking machine. Background Technology

[0002] The dyeing and setting process for fabrics involves dyeing and setting treatments to achieve durable color and stable shape. Chinese utility model patent application No. 202021827127.8 discloses a waterless dyeing and setting machine, including a fabric feeding device, a dyeing tank, a roller, a water-squeezing device, a guide roller type hot air dryer, a drying chamber, and a fabric output device. The roller is immersed in the dye liquor within the dyeing tank. The guide roller type hot air dryer includes a drying oven and two rows of guide rollers located within it. The drying chamber has a mesh belt conveyor. During operation, excess dye liquor is squeezed out by the roller in the dyeing tank, and then the fabric undergoes color development on the guide roller type hot air dryer. Because the fabric contains a certain amount of moisture, color sticking to the guide rollers is likely to occur. Furthermore, during the fabric's transport on the mesh belt conveyor, the fabric to be colored remains relatively stationary on the conveyor, leading to uneven heating, which not only affects the color development effect but also the fabric's hand feel and softness. Utility Model Content

[0003] The purpose of this invention is to provide a fabric dyeing and baking machine.

[0004] The technical solution to achieve the purpose of this utility model is: a fabric dyeing and baking machine, which includes a rolling mill, a pre-drying unit and a drying oven arranged in sequence. Several layers of mesh belt conveyor devices are arranged from top to bottom in the drying oven. The conveying paths of each mesh belt conveyor device are connected end to end. The mesh belt conveyor device includes an annular mesh belt. A shaking device is installed in the annular area of ​​the mesh belt. The shaking device includes a movable vibrating arm. The vibrating arm has a highest displacement point. When the vibrating arm moves to the highest point, it contacts the mesh belt above the vibrating arm. The pressure of the vibrating arm on the mesh belt when it moves to the highest point is limited to the point that can cause the fabric on the mesh belt to shake.

[0005] Furthermore, the vibrating arm includes a spindle and a roller body, the roller body being rotatably mounted on the spindle via bearings. This structure converts the friction between the vibrating arm and the conveyor belt into sliding friction, extending the service life of the vibrating arm.

[0006] Furthermore, the vibration device also includes a motor, a rotating shaft, and a mounting base. Each end of the vibration arm is respectively mounted with a mounting base. The mounting base has an eccentrically formed first positioning hole and a second positioning hole. The spindle of the vibration arm is fixedly connected to the second positioning hole. The rotating shaft passes between the first positioning holes of the two mounting bases and is fixed to the mounting base. The motor is mounted on the frame, and the rotating shaft is drivenly connected to the motor.

[0007] Furthermore, the second positioning hole is a strip-shaped hole, and when the vibrating arm moves to the highest point, the length direction of the second positioning hole is set perpendicular to the horizontal direction.

[0008] Furthermore, a shaking device is installed below the middle position and near the end of the conveying path of the mesh belt conveyor.

[0009] Furthermore, both the rolling mill and the pre-drying unit are installed inside the pre-drying chamber. The pre-drying unit is located above the rolling mill. The rolling mill includes two horizontally tangentially arranged rollers, and the pre-drying unit includes two rows of opposing infrared drying mechanisms. After the wet fabric is vertically exited from the rolling mill, it undergoes non-contact drying using the infrared drying mechanisms, which prevents scorching of the fabric and avoids dye migration and color difference between the front and back sides.

[0010] Furthermore, the pre-drying chamber and the drying oven are provided with hot air inlets on both sides of the fabric conveying path.

[0011] The fabric dyeing and baking machine of this invention has a vibrating arm that contacts the mesh belt above it at its highest point, so that the vibrating arm intermittently pushes the mesh belt upward during the motion cycle, and the fabric shakes on the mesh belt accordingly. During the conveying process, there is a sense of rising and falling, which promotes uniform heating of the fabric, increases the fluffiness of the fabric, and prevents the fabric from hardening after drying.

[0015] Figure 4 This is a schematic diagram of the mounting base described in an embodiment of the present utility model. Detailed Implementation

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] like Figures 1 to 4As shown, a fabric dyeing and baking machine includes a roller 1, a pre-drying unit 2, and a drying oven 3 arranged sequentially. Several layers of mesh belt conveyors 4 are arranged from top to bottom inside the drying oven 3, with the conveying paths of each mesh belt conveyor 4 connected end-to-end. The roller 1 and the pre-drying unit 2 are both installed inside a pre-drying chamber 5, with the pre-drying unit 2 located above the roller 1. The roller 1 includes two horizontally tangentially arranged rollers 11, and the pre-drying unit 2 includes two rows of opposing infrared drying mechanisms 21. Hot air inlets 31 are provided on both sides of the conveying path of the fabric 100 in the pre-drying chamber 5 and the drying oven 3.

[0018] The mesh belt conveyor 4 includes an annular mesh belt 41. Within the annular region of the mesh belt 41, a vibrating device 6 is installed below the conveying path of the mesh belt conveyor 4 at the middle position and near the end of the conveying path. The vibrating device 6 includes a motor 61, a rotating shaft 62, a vibrating arm 63, and a mounting base 64. The vibrating arm 63 includes a spindle 631 and a roller body 632. The roller body 632 is rotatably mounted on the spindle 631 via a bearing 633. A mounting base 64 is installed at each end of the vibrating arm 63. The mounting base 64 has an eccentrically formed first positioning hole 641 and a second positioning hole 642. The spindle 631 of the vibrating arm 63 is fixedly connected to the second positioning hole 642. The rotating shaft... 62 passes through the first positioning holes 641 of the two mounting seats 64 and is fixed to the mounting seats 64. The motor 61 is mounted on the frame (not shown). The rotating shaft 62 is connected to the motor 61 in a transmission manner. The vibrating arm 63 has a highest displacement point A. When the vibrating arm 63 moves to the highest point A, it contacts the mesh belt 41 above the vibrating arm 63. The pressure of the vibrating arm 63 on the mesh belt 41 when it moves to the highest point A is limited to the point that can cause the fabric on the mesh belt 41 to shake.

[0019] Furthermore, the second positioning hole 642 is a strip-shaped hole, and when the vibrating arm 63 moves to the highest point A, the length direction of the second positioning hole 642 is set perpendicular to the horizontal direction.

[0020] During operation, fabric 100 exits vertically via rolling mill 1 and undergoes non-contact drying via infrared drying mechanism 21 within pre-drying chamber 5. Subsequently, fabric 100 enters drying oven 3 and is conveyed by various mesh belt conveyor devices 4 for drying and color development processes. During this process, motor 61 drives rotating shaft 62 to rotate, which in turn drives vibrating arm 63 to intermittently lift mesh belt 41 during the motion cycle, causing fabric 100 to vibrate on mesh belt 41. This vibration gives the fabric a lifting and falling sensation during conveying, promoting uniform heating, increasing fluffiness, and preventing the fabric from becoming stiff after drying.

[0021] This invention features a hot air inlet on the side wall of the oven. Compared to the conventional structure where an air duct is installed above the mesh belt inside the oven, the hot air circulates within the oven, resulting in a more uniform temperature.

[0022] The vibrating arm structure described in this utility model is not limited to the embodiment shown. The roller body can also be fixed to the spindle. This structure will increase the friction when the vibrating arm contacts the mesh belt and shorten the service life of the vibrating arm.

[0023] The structure for driving the vibrating arm to move is not limited to the embodiment described. It can also be moved up and down by a vertical cylinder, as long as the vibrating arm contacts the mesh belt above it when it moves to the highest point, and the pressure of the vibrating arm on the mesh belt when it moves to the highest point is enough to make the fabric on the mesh belt shake.

[0024] The mounting base can be of the following shapes: waist-shaped, triangular, circular, etc.

[0025] The shape of the second positioning hole is not limited to that shown in the embodiment. The shape of the strip hole makes the installation position of the vibrating arm adjustable, thereby adjusting the vibration amplitude of the vibrating arm.

[0026] The structure of the pre-drying unit is not limited to that shown in the embodiment. After the wet fabric is immersed in the roller, it is dried in a non-contact manner by an infrared drying mechanism after being exited vertically by the roller. This will not scorch the fabric, nor will it cause dye migration or color difference between the front and back sides.

[0027] 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.
