Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bolt hot-dip galvanizing equipment, and in particular to a bolt hot-dip galvanizing equipment. Background Technology
[0002] In the field of bolt manufacturing and processing, hot-dip galvanizing is a key process to improve the rust prevention performance of bolts. However, existing hot-dip galvanizing equipment for bolts has many defects in practical applications and is difficult to adapt to the needs of efficient and stable production.
[0003] Currently, the hot-dip galvanizing equipment commonly used in the industry mostly adopts the method of directly immersing bolts in the galvanizing tank. After immersion, the bolts need to be manually retrieved, which is not only cumbersome and inefficient, but also prone to causing burns to personnel due to the splashing of high-temperature galvanizing liquid. At the same time, manual retrieval is difficult to avoid bolt collisions, resulting in scratches and peeling of the coating. Therefore, we propose a bolt hot-dip galvanizing device. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a bolt hot-dip galvanizing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bolt hot-dip galvanizing device, comprising a galvanizing box, a feeding bin slidably installed inside the galvanizing box, an mounting plate fixedly installed at one end of the galvanizing box, a dual-shaft motor fixedly installed on the top of the mounting plate, and drive gears fixedly connected to the output shafts at both ends of the dual-shaft motor, two uprights fixedly installed on the top of the feeding bin, rollers provided on the outer sides of the two uprights, a discharge bin opened in the middle of the feeding bin, a lifting assembly provided on the top of the galvanizing box, and galvanizing liquid lines fixedly installed on both inner walls of the galvanizing box.
[0006] Preferably, a counterweight is fixedly connected between the two uprights, and a connecting shaft is fixedly connected to the outer side of each of the two uprights. The two rollers are rotatably connected to the two connecting shafts.
[0007] Preferably, the bottom inner wall of the discharge bin is provided with several sets of filter holes extending to the bottom, and the several sets of filter holes are distributed in a matrix.
[0008] Preferably, a drive shaft is rotatably mounted on both sides of the galvanized box near the end position. A driven gear is fixedly sleeved on the outer wall of each of the two drive shafts. The two driven gears mesh with the two driving gears respectively. A swing arm is fixedly connected to the end of each of the two drive shafts.
[0009] Preferably, the lifting assembly includes a groove, an adjusting plate, a linkage plate, and a synchronous shaft. The top of the galvanizing box has grooves on the outside of the two uprights. Adjusting plates in the shape of right angle triangles are slidably installed in the two grooves directly below the two rollers. The ends of the two adjusting plates are fixedly connected to the linkage plates. The sides of the two linkage plates that are opposite to each other are fixedly connected to the synchronous shaft.
[0010] Preferably, the two swing arms are provided with inner grooves on the sides that are close to each other, and the two synchronous shafts are slidably connected in the two inner grooves respectively.
[0011] The beneficial effects of this utility model are:
[0012] 1. In use, this utility model utilizes a transmission and lifting structure composed of a dual-shaft motor, a drive gear, a driven gear, a swing arm, a synchronous shaft, and an adjusting plate to achieve automatic lifting of the feeding bin: starting the dual-shaft motor drives the drive gear to rotate, which in turn drives the swing arm to swing through the driven gear. This, in turn, pulls the adjusting plate to slide through the synchronous shaft. The inclined surface of the adjusting plate drives the rollers to lower or raise the feeding bin. Bolts do not need to be manually immersed in the galvanizing tank for soaking, and there is no need for manual retrieval after soaking. This avoids operators coming into contact with high-temperature galvanizing liquid and solves the problem of galvanizing liquid splashing and scalding personnel during manual retrieval. At the same time, it eliminates manual operation steps, significantly shortens the time for soaking and removing bolts, and improves overall production efficiency.
[0013] 2. When using this utility model, the bolts can be directly poured into the discharge bin of the feeding hopper. The discharge bin is an independent holding space, which can prevent the bolts from being randomly stacked and collided during the soaking process. Moreover, the lifting process of the discharge bin is stable, and the bolts are in a stable position in the discharge bin. They will not collide violently due to shaking. Compared with the situation where bolts are prone to friction and collision when manually retrieved, this effectively reduces the scratches and peeling of the coating, ensures the integrity of the zinc coating of the bolts, and ensures the rust prevention effect.

Detailed Implementation
[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-4 As shown, a hot-dip galvanizing device for bolts is disclosed, comprising a galvanizing box 1, a feeding bin 2 slidably installed inside the galvanizing box 1, the feeding bin 2 serving as a carrier for the bolts and lifting them, and capable of immersing or removing the bolts in the feeding bin 10 as a whole into or out of the galvanizing liquid without the need for manual fixing of each bolt, adapting to the batch processing needs of bolts of different specifications, eliminating the need for frequent structural adjustments, and reducing operational complexity. An installation plate 3 is fixedly installed at one end of the galvanizing box 1, and a dual-axis motor 4 is fixedly installed on the top of the installation plate 3. Both ends of the dual-axis motor 4 are fixedly connected to drive gears 5. Two uprights 6 are fixedly installed on the top of the feeding bin 2, and rollers 8 are provided on the outer sides of the two uprights 6. A feeding bin 10 is opened in the middle of the feeding bin 2. A lifting assembly is provided on the top of the galvanizing box 1, and galvanizing liquid lines 12 are fixedly installed on both inner walls of the galvanizing box 1.
[0023] A counterweight 9 is fixed between the two uprights 6, and a connecting shaft 7 is fixed to the outer side of each of the two uprights 6. Two rollers 8 are rotatably connected to the two connecting shafts 7.
[0024] The bottom inner wall of the discharge bin 10 is provided with several sets of filter holes 11 that extend to the bottom. The filter holes 11 are arranged in a matrix. The matrix arrangement of the filter holes 11 allows the zinc plating liquid to enter the discharge bin 10 smoothly when the discharge bin 2 descends. After immersion, the excess zinc plating liquid can be quickly flowed back to the zinc plating box 1, avoiding waste of zinc plating liquid residue, reducing production costs, and reducing the subsequent cleaning process of excess zinc liquid.
[0025] Two drive shafts 13 are rotatably mounted on both sides of the galvanized box 1 near the end. Driven gears 14 are fixedly sleeved on the outer walls of the two drive shafts 13. The two driven gears 14 mesh with the two driving gears 5 respectively. Swing arms 15 are fixedly connected to the ends of the two drive shafts 13.
[0026] The lifting assembly includes a groove 16, an adjusting plate 17, a linkage plate 18, and a synchronous shaft 19. Grooves 16 are provided on the top of the galvanizing box 1, corresponding to the two uprights 6. Adjusting plates 17, shaped like right angles, are slidably installed in the grooves 16, directly below the two rollers 8. Linkage plates 18 are fixedly connected to the ends of the two adjusting plates 17. Synchronous shafts 19 are fixedly connected to the opposite sides of the two linkage plates 18. The dual-axis motor 4 drives the drive gear 5 to rotate, which in turn drives the swing arm 15 to swing via the driven gear 14. The synchronous shaft 19 then pulls the adjusting plates 17 to slide. The inclined surface of the adjusting plates 17 drives the rollers 8, automatically lifting and lowering the unloading bin 2. This eliminates the need for manual loading or unloading of bolts, preventing operators from coming into contact with high-temperature galvanizing liquid and completely eliminating the safety hazard of galvanizing liquid splashing and causing burns during manual unloading. Automatic lifting replaces manual operation, significantly shortening the time for bolt soaking and removal, reducing manual intervention steps, and improving overall production efficiency. It eliminates the need for manual handling of individual bolts, making it suitable for large-scale production needs.
[0027] The two swing arms 15 are provided with inner grooves 20 on the side that are close to each other, and the two synchronous shafts 19 are slidably connected in the two inner grooves 20 respectively.
[0028] Working principle: In use, first, the bolts to be galvanized are poured into the discharge bin 10 on the feeding bin 2. Then, the dual-shaft motor 4 is started. The output shaft of the dual-shaft motor 4 reverses to drive the two mounting plates 3 to rotate synchronously. Since the two driven gears 14 mesh with the two driving gears 5, the two driven gears 14 drive the transmission shaft 13 to rotate in the opposite direction to the driving gears 5. The swing arm 15 pulls the synchronous shaft 19 to one side of the dual-shaft motor 4 with the transmission shaft 13 as the center. During the displacement, the synchronous shaft 19 slides in the inner groove 20. The linkage plate 18 drives the adjusting plate 17 to slide in the groove 16 as the synchronous shaft 19 moves. Since the top of the adjusting plate 17 is inclined, the roller 8 gradually descends along the inclined surface of the adjusting plate 17 when the adjusting plate 17 slides towards the position of the dual-shaft motor 4. The counterweight block set between the two uprights 6 9. The roller 8 moves along the inclined surface of the adjusting plate 17 and rotates at the end of the connecting shaft 7. The discharge bin 2 gradually descends in the galvanizing box 1 as the roller 8 descends. The galvanizing liquid in the galvanizing box 1 enters the discharge bin 10 through several sets of filter holes 11. When the galvanizing liquid in the discharge bin 10 has completely immersed the bolts in the discharge bin 10, the dual-axis motor 4 is turned off. After the bolts in the discharge bin 10 have been immersed, the dual-axis motor 4 is started, causing the output shaft of the dual-axis motor 4 to drive the two drive gears 5 to rotate in the forward direction. The adjusting plate 17 slides towards the upright 6, causing the roller 8 to gradually rise along the inclined surface of the adjusting plate 17. Thus, the roller 8 drives the discharge bin 2 at the bottom of the upright 6 to slide upward in the galvanizing box 1, and the galvanizing liquid in the discharge bin 10 is discharged through several sets of filter holes 11.
