[0047] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0048] like Figure 1-7 As shown, a process card conveying mechanism is used to synchronously convey process cards for a roller hearth furnace, comprising:

[0049] The roller hearth furnace frame 1 has a feeding position and a discharging position at both ends of the roller hearth furnace frame 1 along the material conveying direction;

[0050] The driving source 2 is installed on the roller hearth furnace frame 1 and is located at one end of the discharge position. The driving source 2 is provided with a driving output shaft;

[0051] A driving sprocket 3 is coaxially mounted on the driving output shaft of the driving source 2;

[0052] A driven sprocket 4 is rotatably mounted on the roller hearth furnace frame 1 at one end of the feed position;

[0053] The transmission chain 5 is sleeved on the driving sprocket 3 and the driven sprocket 4;

[0054] A chain speed detection device, the chain speed detection device is coaxially connected to the drive output shaft of the drive source 2, and the chain speed detection device is suitable for detecting the transmission speed of the transmission chain 5;

[0055] A plurality of process card fixing mechanisms are provided on the transmission chain 5 at intervals along the moving direction of the transmission chain 5 , and the process card fixing mechanisms are suitable for fixing and installing process cards.

[0056] In this embodiment, if Figure 2 As shown, during use, the transmission chain 5 is first adjusted to match the conveying speed of the roller-hearth furnace, ensuring that the process card is transported synchronously with the steel inside the furnace. After the material enters the roller-hearth furnace, the process card is placed on the corresponding process card fixing mechanism to ensure synchronous conveying of the process card and the material. This effectively solves the problem of the process card conveying speed being out of sync with the steel advance speed inside the furnace during the process flow. This significantly reduces the need for frequent manual card removal and avoids the problem of material and card mismatch during manual card removal.

[0057] Specifically, such as Figure 1 and Figure 5 As shown, the process card transmission mechanism also includes a tensioning mechanism, which includes:

[0058] Connecting rod 61, the middle part of connecting rod 61 is hinged on the roller hearth furnace frame 1;

[0059] The tensioning wheel 62 is hinged to one end of the connecting rod 61 and meshes with the transmission chain 5;

[0060] The tensioning spring 63 is mounted on the roller hearth furnace frame 1 and abuts against the other end of the connecting rod 61 .

[0061] In this embodiment, if Figure 1-2 As shown, the tensioning mechanism is hinged to the roller-hearth furnace frame 1 at the middle portion of a connecting rod 61, forming a fulcrum. The tensioning spring 63 comprises a spring sleeve fixed to the roller-hearth furnace frame 1 and to the other end of the connecting rod 61, as well as a spring disposed between the roller-hearth furnace frame 1 and the other end of the connecting rod 61. The spring drives the tensioning wheel 62 at the other end of the connecting rod 61 to maintain meshing contact with the transmission chain 5, thereby tensioning the transmission chain 5. The provision of the tensioning mechanism ensures that the transmission chain 5 always maintains appropriate tension during operation, effectively preventing the transmission chain 5 from slacking or slipping during operation.

[0062] Specifically, such as Figure 1-3 As shown, the roller hearth furnace frame 1 is provided with four brackets 11 at intervals along the conveying direction;

[0063] The process card conveying mechanism also includes four guide sprocket groups 7, which are fixedly mounted on corresponding brackets 11 along the conveying direction of the transmission chain 5;

[0064] The guide sprocket assembly 7 comprises:

[0065] The first guide assembly includes an inner upper guide wheel 711 and an inner lower guide wheel 712. The inner upper guide wheel 711 and the inner lower guide wheel 712 are respectively hinged on the bracket 11 and are respectively located above and below the inner side of the transmission chain 5;

[0066] The second guide assembly includes an outer upper guide wheel 721 and an outer lower guide wheel 722. The outer upper guide wheel 721 and the outer lower guide wheel 722 are respectively hinged on the bracket 11 and are respectively located above and below the outer side of the transmission chain 5;

[0067] The inner upper guide wheel 711 and the outer upper guide wheel 721 are arranged in a staggered manner in the vertical direction, and the inner lower guide wheel 712 and the outer lower guide wheel 722 are arranged in a staggered manner in the vertical direction;

[0068] The inner upper guide wheel 711 , the inner lower guide wheel 712 , the outer upper guide wheel 721 and the outer lower guide wheel 722 are all engaged with the transmission chain 5 .

[0069] In this embodiment, if Figure 1-2 As shown, during actual operation, the transmission chain 5 passes between the guide sprocket assemblies 7 and runs along the predetermined track under the constraints of the guide sprocket assemblies 7, effectively preventing the transmission chain 5 from deviation, shaking, and other abnormal conditions. In some embodiments, the number of brackets 11 and guide sprocket assemblies 7 is not limited to four and can be set according to specific needs.

[0070] Specifically, such as Figure 1 As shown, the chain speed detection device may have the following structure, including:

[0071] The encoder is installed on the roller hearth furnace frame 1. The encoder is provided with a rotation detection end, which is coaxially connected to the drive output shaft of the drive source 2.

[0072] In this embodiment, if Figure 1-2 As shown, during operation, the encoder detects the rotation of the drive output shaft and converts mechanical motion into an electrical signal output, enabling real-time monitoring of the operating speed of the transmission chain 5. Because the driving sprocket 3 is coaxially connected to the drive output shaft, the actual operating speed of the transmission chain 5 can be determined. This embodiment also includes a controller, to which the encoder is connected. The controller adjusts the speed of the drive source 2 to ensure that the steel advance speed within the furnace is synchronized with the process card speed. The controller can be a PLC.

[0073] Specifically, such as Figure 1 and Figure 7 As shown, the process card fixing mechanism includes:

[0074] The card limiting support plate 81 is fixed horizontally on the transmission chain 5, and a bearing plane is provided on the card limiting support plate 81;

[0075] The carrying plane is suitable for placing the process card, and the two side edges of the carrying plane are provided with limiting ribs.

[0076] In this embodiment, if Figure 1 and Figure 7 As shown, the operator places the process card on the support surface, and the process card is held in a stable position by the restraint of the retaining ribs. When the transmission chain 5 drives the card retaining plate 81 to move, the retaining ribs prevent the process card from shifting due to inertia or vibration, ensuring that the process card can move stably and reliably in sync with the transmission chain 5.

[0077] Specifically, such as Figure 1 and Figure 7 As shown, the process card fixing mechanism further includes a card fixing fixture 82, and the card fixing fixture 82 includes:

[0078] A single-sided card clip is hinged on the card limiting support plate 81 and is located on the side close to the transmission chain 5;

[0079] An elastic reset component, the middle portion of which is hinged to the unilateral clip, and is provided with a first active end and a second active end, the first active end abutting against the unilateral clip, and the second active end abutting against the card limiting support plate 81;

[0080] Wherein, the single-sided card clip forms a clamping area with the bearing plane of the card limiting support plate 81 under the action of the elastic reset component.

[0081] Specifically, a guiding slope is provided at the end of the single-sided card clip, and a wedge-shaped guiding channel is formed between the guiding slope and the bearing plane of the card limiting support plate 81 .

[0082] In this embodiment, if Figure 7 As shown, during the placement of the process card, the operator inserts the process card along the wedge-shaped guide channel. Guided by the inclined guide surface, the process card smoothly pushes open the single-sided clamp, overcoming the elastic resistance of the elastic return assembly and entering the clamping area. Once the process card is fully positioned, the single-sided clamp automatically clamps the process card under the action of the elastic return assembly, forming a stable clamping force with the supporting surface of the card limit support plate 81, ensuring that the process card will not loosen or fall off during transportation.

[0083] Specifically, such as Figure 1 and Figure 6 As shown, the process card transmission mechanism further includes a driving source protection cover 91 , which is arranged outside the driving source 2 and is fixedly connected to the roller hearth furnace frame 1 .

[0084] Specifically, such as Figure 1 and Figure 6 As shown, the process card transmission mechanism further includes a driving sprocket protective cover 92 , which is arranged outside the driving sprocket 3 and is fixedly connected to the roller hearth furnace frame 1 .

[0085] In this embodiment, if Figure 1 and Figure 6 As shown, in order to ensure the safety of equipment operation, the process card transmission mechanism is provided with a driving source protection cover 91 and a driving sprocket protection cover 92. The driving source protection cover 91 and the driving sprocket protection cover 92 are fixedly connected to the roller hearth furnace frame 1 by bolts.

[0086] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
