[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] A tentering and shaping device is composed of a pressing component and a flattening component.

[0037] The main structures of the pressing assembly and the flattening assembly are the same, both of which are spring-pressing assemblies; the pressing assembly and the flattening assembly are arranged according to the winding direction (moving direction) of the fabric, the spring-pressing assembly on the same side as the moving direction of the fabric is the pressing assembly, and the spring-pressing assembly on the opposite side to the moving direction of the fabric is the flattening assembly.

[0038] Take the structure of the press-fit assembly as an example:

[0039] The pressing assembly is composed of a slide bar 4, a slider 3 and a pressing head 6. The slide bar 4 is horizontally placed in the slider groove 2, and the slider 3 is provided with a horizontal sliding cavity on both sides, and slides along the slide bar 4 through the sliding cavity, and the slide rail based on the slide bar 4 is parallel to the moving direction of the cloth (that is, the preset moving direction of the cloth is horizontal).

[0040] The cavity in the slide rod 4 is a screw cavity, and the top of the slide rod 4 is provided with a transverse groove penetrating to the screw cavity; the screw 5 is arranged in the screw cavity, one end of which is fixed, and the other end is linked by the control device through the driving device A. The rotating screw 5 does not link the slide rod 4. In the longitudinal direction, the slide rod 4 is also provided with a rod cavity penetrating from the screw cavity to the top, and the lower end of the rod cavity is also provided with an extension cavity extending downward and wrapping part of the screw cavity.

[0041] The pressure head 6 is suspended on the top of the slider 3, and the space between the pressure head 6 and the slider 3 is a fabric channel; a longitudinal support rod 1 is fixedly arranged at the bottom of the pressure head 6, and the rod body of the support rod 1 is placed in the rod cavity of the slider 3 and can slide along the rod cavity. When the support rod 1 slides to the bottom along the rod cavity, the bottom end surface of the support rod 1 is screwed to the screw rod 5 through the transverse groove. Preferably, an extension section is also arranged at the bottom end of the support rod 1, and the extension section is preferably provided with a hollow cavity in the longitudinal direction in which the screw rod 5 can be built, so that the extension section can slide up and down with the support rod 1 without touching the screw rod 5.

[0042] Rod magnets 7 are provided on both sides of the support rod 1, reset magnets 9 are provided on both sides of the extension section, and a fixed magnetic attraction device 8 matching the rod magnet 7 and a reset magnetic attraction device 10 matching the reset magnet 9 are provided in the slider 3; that is, when the magnetic attraction device 8 attracts the magnet 7, the bottom end face of the support rod 1 is screwed to the screw 5; when the reset magnet 9 attracts the reset magnet 9, the bottom end face of the support rod 1 is away from the screw 5, that is, it is out of the screw connection state. Correspondingly, on both sides of the support rod 1 and the extension section, a cavity is provided in the slider 3 that can accommodate the sliding of the rod magnet 7, the reset magnet 9 and the extension section at the bottom end of the support rod 1. In the above structure, the reset magnet 9, the extension section and the reset magnetic attraction device 10 constitute the rod reset device of the support rod 1.

[0043] Preferably, the pressure head 6 can be arranged at the top of the support rod 1 through an adjustment structure, and the adjustment structure includes but is not limited to the pressure head 6 being screwed to the top of the support rod 1 in the form of a screw hole, that is, the pressure head 6 can adjust the height at the top of the support rod 1 by rotating the thread, that is, the height of the cloth channel can be adjusted, that is, the pressure of the pressure head 6 on the cloth in the cloth channel can be adjusted.

[0044] A first pressure sensor 11 is provided at the inner side wall of the slider cavity opposite to the direction of cloth translation, and a second pressure sensor 12 is provided at the other inner side wall of the slider cavity. The control device starts the magnetic attraction device 8 according to the feedback of the first pressure sensor 11, closes the magnetic attraction device 8 according to the feedback of the second pressure sensor 12, and drives the magnetic attraction reset device to absorb the reset magnetic block 9 according to the feedback of the second pressure sensor 12 to move the bottom end of the linkage support rod 1 away from the screw 5.

[0045] The slider 3 is also provided with a block reset device, and a reset spring can be selected according to usage requirements: the reset spring can be arranged at any side wall of the slider cavity (in the spring groove), and the outer end of the reset spring is fixedly connected or abutted against the slider 3, and the slider 3 is reset by the tension or elastic force of the stretched or compressed reset spring.

[0046] The structure of the flattening assembly is the same as that of the above-mentioned pressing assembly, but the sliders 3 of the flattening assembly and the pressing assembly are linked to the screw rods 5 in a coaxial and unidirectional manner by the control device disposed therebetween through the driving device A, thereby realizing that the sliders 3 of the pressing assembly and the flattening assembly respectively slide synchronously and in unidirectional directions along the slide rod 4. Preferably, the driving device A can be a coaxial and unidirectional gear set driven by a motor. Specifically, the structure of the coaxial and unidirectional gear set can be selected as follows: Figure 3 The structure shown is composed of Figure 3 The first side shaft 14, the second side shaft 15, the first slave gear 16, and the second slave gear 17 are shown, wherein the first slave gear 16 and the second slave gear 17 are mutually geared, the first side shaft 14 and the second side shaft 15 are coaxially arranged at the top of the first slave gear 16 and the second slave gear 17, and the first side shaft 14 and the first slave gear 16 are geared, and the second side shaft 15 and the second slave gear 17 are geared; the first side shaft 14 and the second side shaft 15 are respectively sleeved on the fixed axis rod. That is, when the second side shaft 15 rotates, the first side shaft 14 is sequentially geared to the second slave gear 17 and the first slave gear 16, and the first side shaft 14 is linked to rotate in a coaxial and unidirectional manner relative to the second side shaft 15, and then the screw rods 5 of the flattening assembly and the pressing assembly are linked to rotate in a coaxial and unidirectional manner, so that the two sliders 3 slide to both sides at the same time.

[0047] Taking the action of pressing components as an example, the action of flattening components is a mirror image of the action of pressing components:

[0048] The initial position of the slider 3 is placed at the inner side wall opposite to the direction of cloth translation. The control device starts the magnetic device 8 according to the feedback of the first pressure sensor 11, so that the bottom end of the support rod 1 is screwed to the screw 5; the control device then drives the coaxial and non-coaxial gear sets driven by the motor to rotate the screw 5, so that the support rod 1 moves laterally along the transverse groove, and at the same time pushes the slider 3 to slide laterally along the slide bar 4. When the slider 3 slides to the inner side wall in the same direction as the cloth translation, the control device closes the magnetic device 8 according to the feedback of the second pressure sensor 12, and at the same time drives the magnetic reset device to absorb the reset magnetic block 9 according to the feedback of the second pressure sensor 12, so that the bottom end of the support rod 1 is away from the screw 5. At this time, the slider 3 is reset to the inner side wall opposite to the direction of cloth translation under the action of the reset spring, and reciprocates in sequence.

[0049] According to usage requirements, a first shaping module 13 can be set on the bottom surface of the pressing head of the flattening component, and a second shaping module can be set on the bottom surface of the pressing head 6 of the pressing component. The first shaping module 13 and the second shaping module are respectively used to further assist the shaping of the fabric by heating, humidification, etc.

[0050] For example:

[0051] When the first shaping module 13 is a first heating component, the second shaping module may be a second heating component or a cooling component; further, as Figure 1 As shown, a humidifying component can also be set at the rear end of the flattening component, combined with the two-stage heating and flattening of the first heating component and the second heating component, to improve the flattening and shaping effect; accordingly, the heating temperature of the first heating component can be lower than the heating temperature of the second heating component to form a stepped heating. When the second shaping module is a cooling component, a two-stage cold pressing shaping effect is performed on the preheated fabric.

[0052] When the first shaping module 13 is a spray (humidification) component, the second shaping module includes a second heating component to further evaporate the water content and shape.

[0053] According to the use requirements, the pressure of the pressing head 6 on the cloth in the cloth channel can be set, preferably: in the magnetic adsorption state, the pressure of the pressing head 6 of the pressing component on the cloth is greater than the pressure of the pressing head of the flattening component on the cloth. In addition, in the magnetic adsorption state, the moving speed of the slider 3 of the pressing component is not greater than the translation speed of the cloth, and the moving speed (reverse direction) of the slider 3 of the flattening component is equal to the moving speed of the slider 3 of the pressing component, and the cloth is further flattened by a slow pulling force.

[0054] 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.
