Description

Technical Field

[0001] The utility model relates to the technical field of coiling of continuous heat treatment furnaces, in particular to a coiling device of the continuous heat treatment furnace. Background Art

[0002] Carbon fiber, due to its excellent physical and chemical properties, is widely used in a variety of fields, including aerospace, automotive, and sports equipment. As a form of carbon fiber, carbon fiber mat typically requires heat treatment during production to improve its properties. During this process, secondary activation heat treatment of the carbon fiber mat using a continuous heat treatment furnace is a crucial step.

[0003] Currently, when performing this type of heat treatment, multiple layers of carbon fiber mat are usually stacked together for the felting process. However, when completing the heat treatment and winding the carbon fiber mat, two major problems are often encountered:

[0004] Untidy curling edges: Since the two ends of the carbon fiber felt cannot be effectively aligned during the winding process, the two ends of the final coil are uneven, affecting the appearance quality and performance of the product.

[0005] Loose winding: If there is not enough tension between the carbon fiber felts during winding, the coil may become loose, reducing the quality and service life of the product. Utility Model Content

[0006] In order to make up for the above shortcomings, the utility model provides a winding device for a continuous heat treatment furnace, which can effectively solve the problem that the rolled felt is not rolled tightly enough, and at the same time can assist in keeping the two ends of the felt to be rolled aligned during the winding process.

[0007] The utility model is realized through the following technical scheme: a winding device of a continuous heat treatment furnace, comprising a felt winding platform of the continuous heat treatment furnace, a plurality of platform rollers arranged on the felt winding platform, a winding roller bracket fixedly arranged at the bottom of the felt winding platform, a winding roller arranged on the winding roller bracket and a crank arranged at one end of the winding roller, characterized in that: a fixed roller bracket fixedly connected to the felt winding platform is arranged in front of the winding roller bracket and corresponds to it; a fixed roller corresponding to the level of the winding roller is arranged on the fixed roller bracket; a gravity roller bracket is hingedly arranged at the left and right end positions of the fixed roller bracket, and a gravity roller is arranged on the gravity roller bracket; an annular positioning plate is fixedly mounted on the platform roller, the winding roller, the fixed roller and the right end of the gravity roller; a sliding positioning member is mounted on the winding roller, the fixed roller and the gravity roller near the left end.

[0008] Furthermore, a positioning bolt hole is provided on the sliding positioning member.

[0009] Furthermore, the length of the gravity roller bracket is half of the distance between the winding roller bracket and the fixed roller bracket.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] Improved winding tightness: By setting up a gravity roller with its own weight, it presses on the carbon fiber mat during the winding process, so that the carbon fiber mat being wound always maintains a certain tension. This design effectively solves the problem of insufficient tightness of the mat caused by the lack of continuous tension in traditional winding methods.

[0012] Ensuring Winding Alignment: This utility model incorporates an annular positioning plate located at the right end of the platform roller, winding roller, fixed roller, and gravity roller. This plate manually aligns one end of the multi-layer carbon fiber felt against the plate, ensuring proper alignment during winding and avoiding irregular edges caused by automatic winding.

[0013] Enhanced winding stability: Sliding locators with positioning bolt holes installed near the winding roller, fixed roller, and gravity roller allow for adjustment of the locators to accommodate carbon fiber mats of varying widths. The locators, in conjunction with the annular positioning plate, not only limit the width of the carbon fiber mat but also prevent it from shifting during winding. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following combination Figure 1-2, the contents of the utility model are described in detail through specific embodiments. Example

[0019] The winding device of the continuous heat treatment furnace includes a felt winding platform 1 of the continuous heat treatment furnace, a plurality of platform rollers 101 arranged on the felt winding platform, a winding roller bracket 2 fixedly arranged at the bottom of the felt winding platform, a winding roller 201 arranged on the winding roller bracket and a crank 202 arranged at one end of the winding roller, wherein: a fixed roller bracket 3 fixedly connected to the felt winding platform is arranged in front of the winding roller bracket and corresponds to it; a fixed roller 301 corresponding to the level of the winding roller is arranged on the fixed roller bracket; a gravity roller bracket 4 is hingedly arranged at the left and right ends of the fixed roller bracket, and a gravity roller 401 is arranged on the gravity roller bracket, wherein the gravity roller bracket can swing with the hinge point of the fixed roller bracket as the center, and the gravity roller is used to press on the carbon fiber felt 7 between the winding roller and the fixed roller, in order to make the rolled felt more compact; the thickness of the planned felt is 2.0~5.0mm, width 1450~1520mm, the weight of the tension roller is about 5~8Kg, and different weights can be selected according to the actual specifications of the felt to avoid the felt being broken by excessive gravity; an annular positioning plate 102 is fixedly mounted on the right end of the platform roller, the winding roller, the fixed roller and the gravity roller, and all the annular positioning plates are in a straight line from back to front. After the treated carbon fiber felt is removed from the continuous heat treatment furnace, one end of the multi-layer carbon fiber felt is manually assisted to be placed against the annular positioning plate so that the two ends of the carbon fiber felt are aligned and maintained in a straight line; a sliding positioning member 5 is mounted near the left end of the winding roller, the fixed roller and the gravity roller, and the sliding positioning member cooperates with the annular positioning plate to limit the width of the carbon fiber felt and prevent the carbon fiber felt from deviating to the left. By moving the sliding positioning member left and right, carbon fiber felts of different widths can be used.

[0020] In order to position the sliding positioning member after defining the width of the carbon fiber felt, a positioning bolt hole 501 is provided on the sliding positioning member, and the sliding positioning member is fixed by tightening a bolt into the positioning bolt hole.

[0021] Preferably, the length of the gravity roller bracket is half of the distance between the winding roller bracket and the fixed roller bracket.

[0022] How it works

[0023] After the treated carbon fiber mat is removed from the continuous heat treatment furnace, one end of the multi-layered carbon fiber mat is manually positioned against a circular positioning plate to maintain alignment. Subsequently, the weight of a gravity roller creates a constant pressure on the carbon fiber mat, ensuring a tight, gap-free mat during rewinding. Furthermore, a sliding positioning element adjusts to the actual width of the carbon fiber mat to prevent lateral shifting during rewinding. The entire rewinding process is completed by turning the rewinding roller with a crank.
