Description

Technical Field

[0001] The utility model relates to the technical field of non-weft belt production, in particular to a non-weft belt production device. Background Art

[0002] The latitude-free tape is an insulating material formed by coating a resin matrix with a plurality of parallel fiber threads, wherein the fiber threads provide a tensile effect, and the resin matrix plays an adhesion effect and a later curing effect. When preparing the latitude-free tape, it is necessary to immerse a plurality of fiber threads in parallel in the resin matrix, and then take them out and dry them to form a semi-dry tape. The existing latitude-free tape production device includes a yarn frame, on which a plurality of pagoda yarns are arranged in parallel, and a roll of fiber threads is arranged on each pagoda yarn. Each fiber thread is guided by a roller assembly into the liquid surface of an immersion tank to absorb the resin matrix, and then leaves the immersion tank and enters a drying mechanism for drying, and then is wound into a roll by a winding mechanism. The fiber threads leaving the immersion tank contain a large amount of resin matrix liquid, and these droplets are brought into the drying mechanism to increase the drying load of the unit, and at the same time, the loss of the resin matrix in the immersion tank is also increased. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a non-weft belt production device, which performs liquid removal treatment on fiber threads before entering a drying box.

[0022] The present invention will be further described in detail below in conjunction with the embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0023] Please refer to Figure 1 , which shows a schematic diagram of a non-weft tape production device in the prior art, which includes a yarn frame 100, a yarn guide hook 200, an immersion tank 300, a drying box 400 and a winding mechanism 500, wherein a plurality of pagoda yarns 110 are arranged in parallel on the yarn frame 100, and a roll of fiber yarns is arranged on each pagoda yarn 110; the immersion tank 300 contains a resin matrix; the yarn guide hook 200 is used to guide the fiber yarns on the pagoda yarn 110 to enter the immersion tank 300 in parallel for immersion, the drying box 400 is used to dry the fiber yarns after being immersed in the resin matrix to form a semi-dry prepreg tape, and the rotating shaft of the winding mechanism 500 is continuously rotated to wind up the semi-dry prepreg tape, thereby forming a rolled tape. In this device, the fiber threads are in a continuous moving state. When they leave the immersion tank 300, their outer walls still carry a large amount of resin matrix droplets. Part of this resin matrix will drip during the movement, and part will be carried into the drying box 400, which will increase the heat load of the drying box 400 and also lead to problems such as large loss of resin matrix.

[0024] Example

[0025] Please refer to Figure 2 to Figure 5 , which shows the structures of two different specific embodiments of the non-weft tape production device of the utility model. The non-weft tape production device of the utility model includes a yarn frame 100, a yarn guide hook 200, an immersion tank 300, a drying box 400, a winding mechanism 500 and a deliquescence mechanism 600, wherein the yarn frame 100, the yarn guide hook 200, the immersion tank 300, the drying box 400 and the winding mechanism 500 are all common components in the existing non-weft tape production device, and will not be described in detail here.

[0026] An important improvement of the present invention over the existing non-wefted belt production device is that a dehydration mechanism 600 is added, which is used to dehydrate the fiber threads after being soaked in the resin matrix, so as to reduce the amount of resin matrix carried by the fiber threads into the drying box 400. In the present invention, the dehydration mechanism 600 is arranged upstream of the drying box 400, and includes a liquid absorption roller 610 and an extrusion roller 620, wherein the outer wall of the liquid absorption roller 610 is provided with a sponge layer 611 for absorbing the liquid (resin matrix) on the fiber threads, and the fiber threads soaked in the resin matrix abut (abut, contact) with the sponge layer 611 of the liquid absorption roller 610, thereby dehydrating the fiber threads soaked in the resin matrix; the extrusion roller 620 is arranged in parallel with the liquid absorption roller 610, such as Figure 4As shown, the distance between the center lines of the absorbent roller 610 and the squeezing roller 620 is less than the sum of the radii of the absorbent roller 610 and the squeezing roller 620. Therefore, the outer wall of the squeezing roller 620 contacts the sponge layer 611 of the absorbent roller 610, and forms an inwardly concave indentation on the sponge layer 611, thereby squeezing and deliquating the sponge layer 611. That is, during use, the sponge layer 611 contacts the fiber thread, thereby deliquating it. After the sponge layer 611 rotates, it is squeezed against the squeezing roller 620, thereby squeezing out the resin matrix in the sponge layer 611 to reduce the amount of resin matrix in the sponge layer 611 and restore its absorption capacity for the resin matrix on the fiber thread. Of course, we can also adjust the absorption capacity of the sponge layer 611 for the resin matrix on the fiber thread by adjusting the distance between the center lines of the absorbent roller 610 and the squeezing roller 620.

[0027] In the present invention, the dehydration mechanism 600 can be as follows Figure 5 As shown, it is arranged between the immersion tank 300 and the drying box 400. In this way, the resin matrix removed by the de-liquidation mechanism 600 can be transferred to the immersion tank 300 for reuse. This is very suitable for the modification of existing devices. A separate de-liquidation unit is set outside the existing device. In this way, the operation of the existing device is slightly affected during the modification. Of course, the de-liquidation mechanism 600 can also be as Figure 2 As shown, it is arranged in the immersion tank 300, so that the resin matrix removed by the removal mechanism 600 directly enters the immersion tank 300 for reuse under the action of its own gravity.

[0028] In the present invention, the dehydration mechanism can be as follows Figure 2 As shown, one set can be set, or two or more sets can be set. When two or more sets are set, they can be set as shown. Figure 5 As shown, at least one set of deliquidation mechanism 600 is arranged above and below the fiber thread soaked in the resin matrix, respectively, for deliquidating both sides of the fiber thread soaked in the resin matrix.

[0029] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the embodiments of the present invention should be covered within the protection scope of the present invention.
