Description

Technical Field

[0001] This utility model relates to the field of wire drawing machines, specifically a drying device for producing wire profiles in wire drawing machines. Background Technology

[0002] When a wire drawing machine produces profiles, the metal raw material (such as copper or aluminum wire) is first passed through the die hole of the wire drawing mechanism and stretched under the drive of the drive device. By controlling the stretching speed and tension, the wire diameter is gradually reduced to the target specification, thus completing the production of a single metal wire (wire drawing). During the wire drawing process, wet lubrication is the main source of moisture. Taking copper and aluminum wire as an example, water tank type wire drawing machines need to immerse the wire in an aqueous solution containing soap or emulsified oil. These water-based lubricants (such as semi-synthetic copper wire drawing fluid S545) can reduce friction and dissipate heat quickly. However, if the lubrication system is not designed properly (such as insufficient pressure or nozzle blockage), the lubricant cannot be evenly distributed, and a water film residue will form on the surface of the wire. In addition, some companies use low-concentration emulsions (such as concentration <2%) to reduce costs, resulting in poor stability of the lubricating film and easier adhesion of moisture. During the wire drawing process, moisture easily accumulates on the surface of the monofilament. When metal wire is exposed to humid air during high-temperature wire drawing, the conductor structure is more easily damaged, affecting product quality and lifespan. Therefore, the use of a drying die during the wire drawing process is a crucial auxiliary device, mainly used to remove residual contaminants (such as moisture, emulsion, etc.) from the surface of the metal wire, while also preventing oxidation and improving surface smoothness. However, when the wire passes through the drying die, it cannot effectively dry the moisture and other residues on the surface of the wire. More importantly, it will wear down the wire, damage the cross-section of the wire, and produce unqualified products. Utility Model Content

[0003] The purpose of this invention is to provide a drying device for producing profiles in a wire drawing machine, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a drying device for producing profiled wire using a wire drawing machine is provided, comprising a drying cylinder, wherein a profiled wire body is inserted inside the drying cylinder and is conveyed by the wire drawing machine; a drying mechanism is installed on one side of the drying cylinder and a drying unit is installed on the other side of the drying cylinder; the drying mechanism includes a drying disc wrapped around the outside of the profiled wire body, and a connecting bearing is installed on the outer ring surface of the drying disc; the outer side of the connecting bearing is fixedly connected to the inner wall of the drying cylinder; the drying unit includes a drying disc and an inner connecting seat.

[0005] Furthermore, a water-blocking mechanism is installed at the end of the drying cylinder. The water-blocking mechanism includes a water-blocking seat and a connecting piece, and the cross-section of the water-blocking seat is a right-angled trapezoid.

[0006] Furthermore, the end of the water-blocking seat is provided with a water-blocking tip, and the distance between the water-blocking tip and the outer ring surface of the profile body is 0.2 to 0.5 mm. At the same time, the axial cross-section of the water-blocking seat, the mating piece and the profile body are concentric circles.

[0007] Furthermore, both the drying mechanism and the drying mechanism are circular. The drying mechanism includes a drying tray, a connecting bearing, a reverse seat, a nozzle, a transmission gear, and a drive gear. Mounting holes are provided on the side walls of both the drying tray and the drying tray. The mounting holes on the drying tray are connected to the air inlet hose, and the mounting holes on the drying tray are connected to the hot air hose.

[0008] Furthermore, the drying tray is movably connected to the inside of the drying cylinder via a connecting bearing, and two sets of inner connecting seats are fixedly provided on the outside of the drying tray, while the drying tray is fixed inside the drying cylinder via the inner connecting seats.

[0009] Furthermore, both the drying tray and the baking tray are fixedly equipped with a reversing seat, and the surface of the reversing seat is provided with an installation slope. At the same time, multiple sets of nozzles are equidistantly arranged on the installation slope, and the spraying direction of the nozzles is opposite to the movement direction of the profile body.

[0010] Furthermore, a transmission gear is installed on the outer side of the drying tray, and a drive gear is installed on one side of the transmission gear. At the same time, the rotating shaft of the drive gear is fixed to the output shaft of the stepper motor. The stepper motor is mounted on the side wall of the drying cylinder through a base. The stepper motor drives the drying tray to reciprocate through the transmission gear and the drive gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution processes the profile body in three stages: a water-blocking mechanism, a drying mechanism, and a baking mechanism. The water-blocking seat on the water-blocking mechanism is close to the outer wall of the profile body, which can scrape off the liquid coming out of the profile body. At the same time, multiple sets of nozzles on the drying mechanism, arranged along the circumference of the profile body, spray gas and impact the outer side of the profile body to perform a first air-drying operation. Finally, multiple sets of nozzles on the baking mechanism spray hot air to perform a second drying operation on the outer side of the profile body, ensuring that there is no moisture or other residue on the surface of the profile body, thereby improving the product qualification rate. 2. This solution uses nozzles that spray in the opposite direction to the movement of the profile body. This counter-current effect prolongs the contact time between the gas and the profile body surface, improving the energy utilization efficiency of the gas sprayed by the drying mechanism and the hot air sprayed by the drying mechanism. Similar to how a counter-current dryer enhances heat exchange, this allows the airflow to fully act on the profile body surface. At the same time, the airflow formed by the reverse spray directly counteracts the movement of the profile body, enhancing the impact and peeling force on the residual liquid on the profile body surface.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a drying device for producing profiled wire using a wire drawing machine, including a drying cylinder 100. A profiled wire body 500 is inserted inside the drying cylinder 100 and is conveyed by the wire drawing machine. A drying mechanism 300 is installed on one side of the inside of the drying cylinder 100, and a drying mechanism 400 is installed on the other side of the inside of the drying cylinder 100. The drying mechanism 300 includes a drying tray 31 wrapped around the outside of the profiled wire body 500, and a connecting bearing 32 is installed on the outer ring surface of the drying tray 31. The outer side of the connecting bearing 32 is fixedly connected to the inner wall of the drying cylinder 100. The drying mechanism 400 includes a drying tray 41 and an inner connecting seat 42.

[0016] Working principle: The wire body 500 is conveyed on the wire drawing machine. This device is installed on the wire drawing machine, and the wire body 500 passes through it. The water-blocking mechanism 200, the drying mechanism 300, and the drying mechanism 400 process the wire body 500 in three stages. The water-blocking seat 21 on the water-blocking mechanism 200 is close to the outer wall of the wire body 500, which can scrape off the liquid coming out of the wire body 500. At the same time, multiple sets of nozzles 331 on the drying mechanism 300, arranged along the circumference of the wire body 500, spray gas, which impacts the outer side of the wire body 500. The process involves air drying the profile body 500 once, followed by a second drying process on the outer side of the profile body 500 using multiple nozzles 331 on the drying mechanism 400. This ensures that the surface of the profile body 500 is free of moisture and other residues, improving the product qualification rate. It also ensures effective separation of moisture and drainage of surface moisture and other residues without abrading the profile body 500. The high-speed airflow blows from the opposite angle to the production movement direction of the profile body 500 to the surrounding area, thoroughly drying the residual moisture on the profile surface and improving the quality of the profile body 500.

[0017] In a preferred embodiment, a water-blocking mechanism 200 is installed at the end of the drying cylinder 100. The water-blocking mechanism 200 includes a water-blocking seat 21 and a connecting piece 22, and the cross-section of the water-blocking seat 21 is a right trapezoid.

[0018] The end of the water-blocking seat 21 is provided with a water-blocking tip, and the distance between the water-blocking tip and the outer ring surface of the profile body 500 is 0.2 to 0.5 mm. At the same time, the axial cross-section of the water-blocking seat 21, the mating piece 22 and the profile body 500 is a concentric circle structure.

[0019] Both the drying mechanism 300 and the drying mechanism 400 are circular. The drying mechanism 300 includes a drying tray 31, a connecting bearing 32, a reverse seat 33, a nozzle 331, a transmission gear 34, and a drive gear 35. The side walls of the drying tray 31 and the drying tray 41 are provided with mounting holes. The mounting holes on the drying tray 31 are connected to the air inlet hose, and the mounting holes on the drying tray 41 are connected to the hot air hose.

[0020] The drying tray 31 is movably connected to the inside of the drying cylinder 100 via the connecting bearing 32, and two sets of inner connecting seats 42 are fixedly provided on the outside of the drying tray 41. At the same time, the drying tray 41 is fixed inside the drying cylinder 100 via the inner connecting seats 42.

[0021] Both the drying tray 31 and the drying tray 41 are fixedly provided with a reverse seat 33, and the surface of the reverse seat 33 is provided with an installation slope. At the same time, multiple sets of nozzles 331 are equidistantly arranged on the installation slope. The spraying direction of the nozzles 331 is opposite to the movement direction of the profile body 500.

[0022] like Figure 1-4As shown: A highly efficient moisture and impurity removal system is formed through three sequential processes: a water-blocking mechanism 200, a drying mechanism 300, and a drying mechanism 400. The water-blocking seat 21 on the water-blocking mechanism 200, being close to the outer wall of the profile body 500, can precisely scrape off the liquid adhering to the surface of the profile body 500, reducing the processing volume of subsequent drying processes and lowering energy consumption from the source. The drying mechanism 300, with multiple sets of nozzles 331 arranged along the circumference of the profile body 500, sprays gas to impact the outer side of the profile body 500 from all directions, avoiding dead zones in drying and ensuring thorough drying. To ensure the uniformity of the initial air drying and prevent localized residual liquid from affecting subsequent processing, the multiple nozzles 331 of the final drying mechanism 400 spray hot air for secondary drying. This effectively removes trace amounts of residual moisture from the surface of the shaped wire body 500, further enhancing the drying effect. The design of multiple nozzles 331 ensures that hot air evenly covers the shaped wire body 500, preventing uneven heating that could damage its quality. Overall, the goal of efficient, thorough, and uniform removal of moisture from the shaped wire body 500 is achieved, ensuring its performance in subsequent processing stages. The spray direction of nozzle 331 is opposite to the movement direction of the profile body 500. This counter-current effect prolongs the contact time between the gas and the surface of the profile body 500, improving the energy utilization efficiency of the gas ejected by the drying mechanism 300 and the hot air ejected by the drying mechanism 400. Similar to how a counter-current dryer enhances heat exchange, this allows the airflow to fully act on the surface of the profile body 500. Simultaneously, the airflow generated by the reverse spray directly counteracts the movement of the profile body 500, enhancing the impact and peeling force on residual liquids on the surface of the profile body 500. This is especially effective against liquids in recesses or dead corners, and can be combined with the water-blocking mechanism 20. The water-blocking seat 21 on the 0 pushes the liquid in the direction of water blocking, reducing the processing burden of the downstream drying process. In addition, the reverse airflow can form a more turbulent flow field around the profile body 500, avoiding the problem of airflow slipping along the surface when flowing with the current. This ensures that the medium sprayed by multiple sets of nozzles 331 evenly covers the entire circumference of the profile body 500, eliminating drying dead corners and improving the uniformity of air drying and baking. Moreover, this design can prevent the dried area from being re-contaminated by the moisture brought back by the subsequent airflow, so that the profile body 500 can gradually complete the progressive treatment from coarse dehydration to deep drying during the transportation process, ultimately improving the stability of the overall drying effect.

[0023] In a preferred embodiment, a transmission gear 34 is also installed on the outer side of the drying tray 31, and a drive gear 35 is installed on one side of the transmission gear 34. At the same time, the rotating shaft of the drive gear 35 is fixed to the output shaft of the stepper motor 351. The stepper motor 351 is mounted on the side wall of the drying cylinder 100 through a base. The stepper motor 351 drives the drying tray 31 to reciprocate through the transmission gear 34 and the drive gear 35.

[0024] like Figure 1-2As shown: A transmission gear 34 is mounted on the outer side of the drying tray 31 and meshes with the drive gear 35. Driven by a stepper motor 351, it achieves slow reciprocating rotation. This reciprocating rotation causes multiple sets of nozzles 331 on the drying tray 31 to form a dynamic scanning airflow coverage. Combined with reverse gas injection, this creates a more complex turbulent field, significantly increasing the contact area and contact time between the profile body 500 surface and the airflow. This is especially effective in enhancing the airflow impact in recesses or dead corners, effectively removing residual moisture and solving the drying blind zone problem that is easily caused by fixed nozzles. The stable structure of the gear transmission ensures smooth movement of the drying tray 31, reducing vibration interference with the conveying of the profile body 500. Simultaneously, after the water-blocking mechanism 200 is scraped off... The residual moisture is pushed towards the water-blocking direction by the airflow rotation, reducing the processing burden of the downstream drying mechanism 400 and avoiding secondary contamination of the dried area; the entire mechanism is firmly installed on the side wall of the drying cylinder 100 through the base, realizing efficient power transmission in a compact space, ensuring both transmission efficiency and operational stability, and without affecting the continuous conveying of the profile body 500. Ultimately, through precise control, dynamic action and system synergy, the drying uniformity, efficiency and adaptability of the equipment to diverse production needs are comprehensively improved; the drying tray 31 is supplied with air by a hose. Since the drying tray 31 is in a state of slow reciprocating rotation, the hose supplies air to the drying tray 31 without motion interference.
