Description

Technical Field

[0001] The invention relates to a heating device, in particular to a heating device suitable for cloth stretching. Background Art

[0002] Tentering is a finishing process that uses the plasticity of cellulose, silk, wool and other fibers under wet conditions to gradually widen the fabric width to a specified size and dry it to stabilize it. Tentering finishing can reduce the deformation of the fabric during use.

[0003] Commonly used stenting equipment includes cloth clip stenter and pin plate stenter. The cloth clip stenter consists of many cloth clips with a length of about 10 cm connected into a live clip chain, which are placed flat on the left and right tracks and run cyclically along the tracks. The distance between the left and right tracks can be adjusted in sections. The distance at one end of the fabric inlet is relatively close, and then the distance gradually increases, so that the fabric can be stretched to the required width. When the fabric enters the stenter, the two sides are clamped by the cloth clips and move forward with the cloth clips. When the fabric leaves the machine, the cloth clips are opened and the two sides are separated. During the stenting process, the fabric is gradually dried by hot air. The pin plate stenter uses pin plates instead of cloth clips, and its mechanical structure is similar to that of the cloth clip stenter. During the stenting process, the two sides of the fabric are fixed on the pin plates. The front end of the pin plate stenter can be equipped with an overfeed device. The fabric entry speed is slightly higher than the forward speed of the pin plate to form overfeed, so that the fabric shrinks more in the warp direction during the stenting process to reduce the warp shrinkage of the product. The stentering of wool fabric or its blended fabric can be carried out on a multi-layer reciprocating pin plate stentering machine. The stentering machine can also be used for drying fabrics and heat setting of synthetic fibers.

[0004] However, the heat drying device in the existing stenter is relatively simple, with a fixed heating direction and mode, directional or biased heating, and is large in size and occupies a large area. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, an object of the present invention is to provide a heating device suitable for cloth stretching.

DETAILED DESCRIPTION

[0030] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 As shown, four groups of heating devices 2 are arranged between a group of cloth guide rollers 1. According to the use requirements, the four groups of heating devices 2 can be arranged in a parallel circuit manner for individual and separate operation; or they can be arranged in a series circuit manner for unified operation.

[0032] The heating device 2 is composed of a magnetic suspension disk, a limiting assembly, and an electromagnetic heating coil 11. The limiting assembly is the main structure, and the longitudinal section of the limiting assembly is in the shape of a "[]", that is, the top and bottom surfaces of the rectangular frame are both open, wherein the top surface opening is the top opening 12, and the bottom surface opening is the bottom opening. The magnetic suspension disk is placed in a rectangular cavity between the top opening 12 and the bottom opening, and is limited by the top opening 12 and the bottom opening, which have a diameter smaller than that of the magnetic suspension disk, that is, the top surface of the rectangular frame constitutes a first limiting structure, and the bottom surface of the rectangular frame constitutes a second limiting structure.

[0033] The magnetic suspension disk is disc-shaped as a whole, and consists of a heating steel body 8 in the inner ring and a suspension component in the outer ring. An insulation layer is also provided between the heating steel body 8 and the suspension component, that is, between the inner ring and the outer ring, including an asbestos insulation layer 9 wrapping the inner ring and a hollow insulation layer 10 (cavity) surrounding the asbestos insulation layer 9. The top and bottom surfaces of the heating steel body 8 are respectively provided with a plurality of grooves based on the center line, the top surface is provided with a plurality of first grooves 13 forming a fan shape, and the bottom surface is provided with a plurality of second grooves forming a fan shape. The first magnetic ring 4 is provided on the bottom surface at the outer ring, and the fourth magnetic ring 7 is provided on the side surface at the outer ring.

[0034] The second magnetic ring 5 matching the first magnetic ring 4 is annularly arranged on the top surface of the second limiting structure, and the opposite surfaces of the first magnetic ring 4 and the second magnetic ring 5 have the same magnetic properties; the first magnetic ring 4 and the second magnetic ring 5 constitute a suspension magnetic group of the magnetic suspension disk. Preferably, the second magnetic ring 5 is an electromagnet, and the power module supplies power to the electromagnet through the control device.

[0035] The third magnetic circle 6 matching the fourth magnetic circle 7 is arranged in a ring shape along the inner wall of the rectangular frame, and preferably, the third magnetic circle 6 is arranged at the upper end of the inner wall of the rectangular frame. The third magnetic circle 6 and the fourth magnetic circle 7 constitute the guide magnetic group of the magnetic suspension disk; and the third magnetic circle 6 and the fourth magnetic circle 7 are respectively composed of a plurality of arc-shaped magnets arranged in sequence in opposite magnetic properties.

[0036] The guiding magnet group and the suspension magnet group constitute a suspension component.

[0037] The electromagnetic heating coil 11 is embedded in the bottom opening and is arranged opposite to the bottom of the heating steel body 8.

[0038] The control device drives the power module to supply power through the control device. Preferably, the center lines of the magnetic suspension disk, the top opening 12 and the bottom opening are unified.

[0039] According to the use requirements, a plurality of atomizing nozzles 3 can be arranged around the inner wall of the first limiting structure; the nozzle provides a water source for the atomizing nozzle 3, and the nozzle can be concealedly arranged inside the first limiting structure.

[0040] When using,

[0041] The control device supplies power to the electromagnet, causing the electromagnet (second magnetic ring) to generate magnetism. Based on the principle of like charges repelling each other with the first magnetic ring, the magnetic suspension disk is suspended in the rectangular frame and is restricted by the first limiting structure and the second limiting structure.

[0042] The suspended magnetic suspension disk rises to the height of the third magnetic circle 6. Since the third magnetic circle and the fourth magnetic circle 7 are composed of magnets arranged in sequence with opposite magnetic properties, taking any magnet in the fourth magnetic circle 7 as an example, one end is subjected to repulsive force (by the adjacent magnet in the third magnetic circle) and the other end is subjected to attractive force, so that the suspended magnetic suspension disk rotates, and enters the next adjacent magnet based on the inertia of rotation, and rotates cyclically in sequence under the action of repulsive force and attractive force.

[0043] The fan on the top of the rotating magnetic suspension plate faces the bottom surface of the cloth between the guide rollers 1.

[0044] When the atomizing nozzle 3 is turned on, the wind from the fan blows the atomized water vapor toward the fabric, achieving a wetting effect.

[0045] When the control device supplies power to the electromagnetic heating coil 11, an alternating magnetic field is generated; the suspended heating steel body 8 cuts the alternating magnetic field lines and generates alternating current (i.e. eddy current). The eddy current causes the carriers to move irregularly at high speed, and the carriers collide and rub against atoms to generate heat energy, i.e. electromagnetic heat.

[0046] The heat rises upward, and the wind generated by the rotating magnetic suspension plate is blown toward the bottom of the fabric in a direction. Combined with the atomized water vapor, it has a moist heat effect, which smoothes out wrinkles and reduces the shrinkage of the fabric.

[0047] Because the heated steel body dissipates heat not only from the top surface but also from the bottom surface; the heat dissipated from the bottom surface is accumulated in the rectangular cavity and then blown out from the top opening 12 by the wind generated by the rotation of the fan on the bottom surface of the heated steel body, dissipating heat and utilizing the heat again.

[0048] In actual use, if multiple sets of heating devices 2 are connected in parallel, they can be used flexibly, such as intermittent humidification and intermittent heating, extending the wetting time through separate humidification and enhancing the heating effect through separate heating.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
