Description

Technical Field

[0001] This utility model relates to the field of tire bead wire production technology, specifically to a drying box structure that allows for rapid wire threading. Background Technology

[0002] As a material used in the rubber tire skeleton, the bead wire requires bronze plating to enhance its bonding with the rubber. The production process includes unwinding, impurity removal, degreasing, electrolytic alkaline washing, hot water rinsing, drying, MF ultrasonic heating, water cooling, electrolytic acid washing, water rinsing, hydrochloric acid washing, water rinsing, electrolytic acid washing, bronze plating water rinsing, weak alkaline washing, water rinsing, hot water washing, drying, coumar coating, and air drying. The drying stage, downstream of the hot water washing, primarily dehydrates the steel wire surface quickly to ensure the smooth operation of subsequent processes.

[0003] Existing production lines generally use high-temperature drying ovens as drying equipment, achieving surface moisture evaporation of the steel wires through hot air circulation. The drying oven has wire-threading ports at both ends and an internal heating element to maintain a high-temperature working environment of 120-150℃. Before production, the top cover of the drying oven must be opened while it is not heated. Dozens of steel wires are manually pulled parallel to each other and threaded into the oven. After the spacing is adjusted by the wire-separating wheels at the front and back of the oven, the cover is closed and the heating is activated. During production, the steel wires move continuously through the drying oven, and the high-temperature airflow completes the drying process.

[0004] In actual production, wire breakage can occur due to multiple factors such as equipment operating conditions, material properties, and process parameters. When the broken wire is located upstream of the drying oven, the oven cover, which is under high temperature, needs to be reopened for wire threading. The instantaneous release of high-temperature steam upon opening the cover can easily cause burns to operators, posing a safety hazard. Furthermore, the internal thermal environment of the oven is rapidly disrupted by opening the cover, resulting in significant heat loss and requiring the equipment to be heated for an extended period to restore thermal equilibrium. This not only affects production but also wastes energy. Utility Model Content

[0005] The purpose of this utility model is to provide a drying box structure that allows for quick wire threading, making it easy to re-thread the steel wire into the drying box when the wire breaks, without opening the cover, reducing the possibility of steam overflow causing burns to operators, and reducing heat loss due to opening the cover, thereby improving the stability of drying.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a drying box structure that can quickly thread wires includes a drying box body with threading ports at both ends, a guide tube extending through the drying box body along its length direction and located on one side of the threading port, a connection port communicating with the threading port on the tube wall, a threading rod detachably threaded through the guide tube, the length of the threading rod being greater than the total length of the drying box body, and a fixing member for connecting to a steel wire at one end of the threading rod.

[0007] A further improvement of this utility model is that the fixing member is a wire-fixing head provided at one end of the threading bar, and the wire-fixing head is provided with a winding hole, through which the steel wire is bent and fixed.

[0008] A further improvement of this invention is that the diameter of the guide tube is greater than the width of the threading opening.

[0009] A further improvement of this utility model is that the threading bar includes an insertion section and a holding section, the length of the insertion section is greater than the total length of the drying chamber, and the thread fixing end is disposed at the end of the insertion section.

[0010] A further improvement of this utility model is that the gripping section is made of heat-insulating material and has a ring plate coaxially arranged on it. The diameter of the ring plate is larger than the diameter of the guide tube and has a notch to facilitate the passage of steel wire.

[0011] A further improvement of this utility model is that the guide tube is provided in two parts, located on both sides of the length direction of the threading opening.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model features a guide tube connected to the wire threading port on one side of the drying chamber. By inserting a wire threading rod inside the guide tube, it is easy to re-thread the steel wire into the drying chamber when the wire breaks, without having to open the cover. This reduces the possibility of steam overflow causing burns to operators and also reduces heat loss due to opening the cover, thus improving the stability of drying.

[0014] In the prior art, since the overall length of the drying chamber is relatively long (generally more than 4m), if a threading rod is directly inserted into the threading opening, the rod can only be operated by hand at one end, and there is no effective constraint at the far end. During the long-distance advancement, the threading rod may deviate due to gravity or resistance. The threading rod may collide or become entangled with other moving steel wires inside the chamber. However, this utility model can constrain the guide tube by setting a guide tube, which facilitates the smooth insertion of the threading rod and realizes the rapid threading of steel wires.

[0015] This utility model, by setting a wire-fixing end with a winding hole, facilitates quick and easy winding, bending, and fixing of the steel wire, and makes it easy to disassemble, thereby improving the efficiency of re-threading broken wires.

[0016] This invention provides protection when gripping by setting a ring plate on the gripping section, and also limits the depth to which the threading rod penetrates into the guide tube, making it easier to position. Attached Figure Description

[0022] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: Combination Figures 1-4 It is known that a drying box structure that can quickly thread wires includes a drying box body 2 with threading ports 1 at both ends. A guide tube 3 is provided through the drying box body 2 along its length direction and located on one side of the threading port 1. A connection port 4 communicating with the threading port 1 is provided on the tube wall of the guide tube 3. A threading rod 5 is detachably threaded through the guide tube 3. The length of the threading rod 5 is greater than the total length of the drying box body 2. One end of the threading rod 5 is provided with a fixing part that is connected to the steel wire.

[0024] Preferably, the horizontal height of the connection port 4 is higher than the horizontal height of the moving steel wire.

[0025] The fixing component is a wire-fixing end 6 located at one end of the threading rod 5. The wire-fixing end 6 has a winding hole 7. The steel wire passes through the winding hole 7 and is then bent and fixed. By fixing the steel wire by bending, the connection can be completed without complicated tools.

[0026] Optionally, the wire end 6 is made of stainless steel. Tie the broken wire to the fixing piece, and pass the wire threading rod 5 from one end of the guide tube 3 to the other end to pass the wire through the drying chamber 2. Then adjust the wire to the position of the broken wire.

[0027] The diameter of the guide tube 3 is larger than the width of the threading opening 1, which facilitates the insertion of the threading rod 5.

[0028] The threading rod 5 includes an insertion section and a holding section. The length of the insertion section is greater than the total length of the drying chamber 2 to ensure that it can completely penetrate the chamber. The wire end securing 6 is located at the end of the insertion section. The holding section is made of heat-insulating material. Preferably, both the insertion section and the holding section are made of fiberglass.

[0029] Optionally, a ring plate 9 is coaxially provided on the gripping section. The diameter of the ring plate 9 is larger than the diameter of the guide tube 3 and it is provided with a notch to facilitate the passage of the steel wire. Optionally, the notch is a U-shaped notch.

[0030] Preferably, there are two guide tubes 3, located on both sides of the threading port 1 along its length, so that the thread can be re-threaded from the closer side according to the different broken wire positions.

[0031] The working principle of the drying box structure that allows for quick threading provided by the utility model is as follows:

[0032] When a wire breaks, pull the threading rod 5 out of the guide tube 3, pass one end of the broken wire through the winding hole 7 and bend it to fix it. Then push the threading rod 5 into the guide tube 3. The guide tube 3 constrains the direction of the threading rod 5. The threading rod 5 is guided and its end with the fixed wire head 6 can quickly pass out from one end of the guide tube 3. Then unwrap the wire from the fixed wire head 6. With the cooperation of two workers on both sides of the drying chamber 2, straighten the wire and move the straightened wire from the connection port 4 to the threading port 1. Then raise the wire and move it to the broken wire position to put it back in place. Then limit it with the dividing wheels at both ends of the drying chamber 2. The threading operation of the drying chamber with broken wire is completed.
