Description

Technical Field

[0001] This utility model relates to a pretreatment device for hot-dip galvanized workpieces. Background Technology

[0002] In the hot-dip galvanizing process, the pretreatment of the workpiece is one of the key steps to ensure the quality of galvanizing.

[0003] Traditional hot-dip galvanizing pretreatment requires processing in three different locations: a pickling tank, a washing tank, and a dryer. During the dryer process, the workpieces to be dried are typically placed inside the dryer, and heat generated by the fan and heating plate is diffused into the processing chamber to dry the workpieces. However, the liquid water adhering to the workpiece surface after washing cannot be quickly wiped away, thus affecting the drying efficiency and the quality and uniformity of the subsequent galvanized layer. Therefore, a pretreatment device for hot-dip galvanizing workpieces is proposed. Utility Model Content

[0005] To solve the above technical problems, the present invention provides the following technical solution: a pretreatment equipment for hot-dip galvanized workpieces, including a dryer for drying hot-dip galvanized workpieces, wherein a conveyor belt for conveying hot-dip galvanized workpieces is provided at the dryer, and an inlet and an outlet for hot-dip galvanized workpieces are respectively provided on both sides of the conveyor belt.

[0006] A wiping assembly for absorbing liquid water from the surface of hot-dip galvanized workpieces is provided at the inlet.

[0007] The dryer uses a wiping assembly to perform a drying pretreatment on the hot-dip galvanized workpiece.

[0008] Preferably, the wiping assembly includes two sets of support rods located at the inlet, each support rod is connected to a support seat via a baffle, the support seat is connected to a connecting seat via a connecting rod, a rolling rod is rotatably connected inside the connecting seat, and an absorbent cloth is wrapped around the outer periphery of the rolling shaft.

[0009] Preferably, the bearing seat has a channel inside for the movement of the connecting rod, and a retaining ring is provided inside the channel to restrict the movement of the connecting rod.

[0010] Preferably, a return spring is provided on the outer periphery of the connecting rod, and the return spring is located inside the channel so that the connecting rod can move elastically inside the channel by means of the return spring.

[0011] Preferably, guide grooves are provided on both sides of the bearing seat, and guide rods are slidably connected inside the guide grooves. The side of the guide rod away from the bearing seat is connected to the connecting seat.

[0012] Preferably, a limiting plate is provided on the upper part of the connecting rod, and the outer diameter of the limiting plate is larger than the inner diameter of the retaining ring, so that the connecting rod can limit its stroke by passing through the limiting plate.

[0013] Preferably, a wiping cloth is provided on the inner side of the baffle so that the wiping cloth can wipe the hot-dip galvanized workpiece on the conveyor belt.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting a wiping component at the inlet of the dryer, can quickly absorb and wipe liquid water on the surface of hot-dip galvanized workpieces, thereby accelerating the drying process and improving drying efficiency.

[0016] By using the absorbent cloth and wiping cloth of the wiping component, moisture and impurities on the surface of the workpiece can be removed more effectively, ensuring that the workpiece has a cleaner surface before entering the dryer, which is crucial for the quality and uniformity of the subsequent galvanized layer.

[0017] By reducing moisture and impurities on the workpiece surface, defects such as bubbles and spots during the galvanizing process can be reduced, thereby improving the overall quality and uniformity of the galvanized layer.

[0018] The equipment is highly automated, which reduces the need for manual wiping and handling of workpieces, lowers labor intensity, and reduces the impact of human factors on pretreatment quality. Attached Figure Description

[0026] Please see Figure 1-5 This utility model provides a pretreatment equipment for hot-dip galvanized workpieces, including a dryer 1 for drying hot-dip galvanized workpieces. The dryer 1 is provided with a conveyor belt 2 for conveying hot-dip galvanized workpieces. The dryer 1 is provided with an inlet 3 and an outlet 4 for hot-dip galvanized workpieces on both sides of the conveyor belt 2.

[0027] A wiping assembly 5 for absorbing liquid water from the surface of hot-dip galvanized workpieces is provided at the inlet 3. The wiping assembly 5 includes two sets of support rods 501 located at the inlet 3. The support rods 501 are connected to support seats 503 via baffles 502. The support seats 503 are connected to connecting seats 505 via connecting rods 504. A rolling rod is rotatably connected inside the connecting seat 505. An absorbent cloth 507 is wrapped around the outer periphery of the rolling shaft 506. A channel 5031 for the movement of the connecting rod 504 is provided inside the support seat 503. A retaining ring 5032 for restricting the movement of the connecting rod 504 is provided inside the channel 5031. A return spring 508 is provided on the outer periphery of the connecting rod 504. The return spring 508 is located inside the channel 5031 so that the connecting rod 504 can move elastically within the channel 5031 via the return spring 508. Guide grooves 5033 are provided on both sides of the support seat 503. Guide rods 5034 are slidably connected inside the guide grooves 5033. The side of the guide rods 5034 away from the support seat 503 is connected to the connecting seat 505. A limiting plate 5041 is provided on the upper part of the connecting rod 504, and the outer diameter of the limiting plate 5041 is larger than the inner diameter of the retaining ring 5032, so that the travel of the connecting rod 504 is limited by the limiting plate 5041. A wiping cloth 509 is provided on the inner side of the cover plate 502, so that the wiping cloth 509 can wipe the hot-dip galvanized workpieces on the conveyor belt 2.

[0028] The dryer 1 uses the wiping assembly 5 to perform a drying pretreatment on the hot-dip galvanized workpiece.

[0029] The working principle of the hot-dip galvanized workpiece pretreatment equipment provided by this utility model is as follows: When in use, the hot-dip galvanized workpiece to be dried is placed on the conveyor belt 2 and transported to the inlet 3 by the conveyor belt 2.

[0030] The workpiece abuts against the bottom of the rolling shaft 506. The connecting rod 504 moves upward through the connecting seat 505 to squeeze the return spring 508. The return spring 508 is compressed and deformed. At the same time, the elastic force is applied to the surface of the workpiece through the adsorption cloth 507 at the rolling shaft 506. The liquid water and impurities on the surface of the workpiece are adsorbed by the adsorption cloth 507.

[0031] When the workpiece moves to the inside of the dryer 1 through the adsorption cloth 507, the wiping cloth 509 wipes away the residual liquid water and impurities on the surface of the workpiece by gravity.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
