The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.
The embodiment of the utility model provides a pressing device capable of discharging materials under controllable tension, which is used for pressing a material belt and a double-sided adhesive tape to form a composite belt.
Referring to fig. 1, the pressing device for discharging materials with controllable tension includes a pressing roller set 1, a first unwinding device 2, and an induction assembly 3 electrically connected to the first unwinding device 2;
the first unwinding device 2 is used for outputting the material belt, and the pressing roller set 1 is used for pressing the material belt and the double-sided adhesive tape. Wherein, the material area can be the material area of bubble cotton material, silicon rubber material or other materials.
A material containing space 100 in which a feeding belt falls is formed between the first unreeling device 2 and the press roller group 1; a section of material belt between the first unreeling device 2 and the press roller set 1 is in a U-shaped structure in the material containing space 100; the sensing assembly 3 is used for detecting position information of the lowest point of the U-shaped structure and controlling the unwinding speed of the first unwinding device 2 according to the detected position information, so that the position of the lowest point of the U-shaped structure is within a preset interval.
Specifically, since the position of the lowest point of the U-shaped structure is within the predetermined interval, which is equivalent to keeping the length of the material belt in the material containing space 100 within a relatively stable length range, the self-reuse of the material belt in the material containing space 100 will affect the tension of the material belt entering the nip roller set 1, thereby keeping the tension of the material belt entering the nip roller set 1 stable. At this moment, even if the laminating speed of the laminating roller set 1 is different from the unreeling speed of the first unreeling device 2, the position of the lowest point of the U-shaped structure is always in the preset interval, so that the material belt is not laminated between the double-sided adhesive tape and the double-sided adhesive tape in the state of overlarge tension, and the flatness of the composite belt is favorably guaranteed. It should be clear that the predetermined interval can be set according to the actual required production tension, for example, for different materials and different thicknesses of the material strips, different predetermined intervals need to be set correspondingly.

Specifically, when the light sensor is used to control the lowest position of the material strip in the material accommodating space 100, the lowest position of the material strip in the material accommodating space 100 fluctuates around the height value of the light sensor, and at this time, the length of the material strip in the material accommodating space 100 remains substantially unchanged, so as to well maintain the tension of the material strip entering the nip roller set 1. It is worth noting that the specific height of the light sensor needs to be determined according to the actual production tension.

The material belt is firstly bonded with the adhesive surface of the double-sided adhesive tape before entering the press roller set 1, so that a composite belt with poor flatness is easily formed, and the flatness of the composite belt is not favorably improved.

It should be clear that the carrier roller 4 is located right above the stitching roller set 1, the material belt hangs down from the top of the stitching roller set 1 and then enters the stitching roller set 1 for stitching, and the tension of the material belt entering the stitching roller set 1 is extremely small, so that the flatness of the composite belt can be improved, and the composite belt can be kept in a flat state for a long time. Bearing roller 4 is located pressing roller set 1 directly over, has avoided the weight in material area to make the material area the condition of tensile state to can promote the roughness in composite band well. Particularly, when the length of the material belt between the support roller 4 and the pressing roller group 1 is equal to the length of the material belt between the support roller 4 and the lowest point of the material belt in the material accommodating space 100, the tension of the material belt entering the pressing roller group 1 is the smallest at this time, and the flatness of the composite belt formed by pressing is better.
Optionally, the first unwinding device 2 comprises a freely rotatable material-bearing drum 21 and a feed roller set 22 for pinching the material belt, wherein the material-bearing drum 21 is used for storing the material belt coil; the feeding roller group 22 comprises a driven feeding roller 221, an active feeding roller 222, a telescopic device for driving the active feeding roller 222 to move towards the driven feeding roller 221 and a driving motor for driving the active feeding roller 222 to rotate;
