Description

Technical Field

[0001] The utility model relates to the technical field of wire thread insert dip coating processing, in particular to a surface coating device for wire thread inserts. Background Technique

[0002] A wire thread insert is an industrial accessory used to enhance the strength and wear resistance of threaded connections. It is usually made of high-strength steel material. By inserting it into a pre-processed hole, it provides additional internal threads for easy maintenance and extended service life. Wire thread inserts are widely used in fields such as machinery, automobiles, and electronics. They have excellent corrosion resistance and wear resistance, and can reduce connection failure problems caused by thread wear. During the production process of wire thread inserts, coating treatment is required. The coating can improve the corrosion resistance and wear resistance of wire thread inserts, extend their service life, prevent rust and corrosion, and at the same time enhance the surface hardness, reduce wear, and ensure the stability and reliability of threaded connections.

[0003] Dip coating is one of the surface coating methods for wire thread inserts. By immersing the wire thread inserts in molten coating, a coating layer is formed on their surfaces. This method can ensure a uniform and strong adhesion coating. In the traditional dip coating process of wire thread inserts, the wire thread inserts are concentrated and placed in a storage frame, and the storage frame is sunk into the dip coating tank for dip coating processing. However, the wire thread inserts are stacked in the storage frame, and there is mutual contact and shielding between them. During dip coating, the contact and shielding parts are difficult to fully contact the coating, resulting in uneven dip coating and affecting the quality of dip coating processing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a surface coating device for wire thread inserts, which effectively solves the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions.

[0006] A surface coating device for wire thread inserts includes a dip coating tank, a rotating disk, an arc-shaped baffle, and a driving mechanism. The arc-shaped baffle is installed in the dip coating tank through a first bracket arranged on the inner bottom wall of the dip coating tank. A number of vertically penetrating through holes are evenly distributed on the arc-shaped baffle. Both ends of the arc-shaped baffle extend to the upper part of the dip coating tank, and one end is the feeding part and the other end is the discharging part. The rotating disk is installed above the arc-shaped baffle through a driving mechanism arranged on the dip coating tank. The outer edge wall of the rotating disk is slidably and fittingly attached to the inner edge wall of the arc-shaped baffle. A number of temporary storage grooves for accommodating wire thread inserts are arranged in a circular array around its axis on the outer edge wall of the rotating disk. The driving mechanism is used to drive the rotating disk to rotate.

[0007] Furthermore, as the rotating disk rotates, when the temporary storage groove moves to a position corresponding to the feeding part, its opening is inclined upward, and when the temporary storage groove moves to a position corresponding to the discharging part, its opening is inclined downward.

[0008] Furthermore, the driving mechanism includes a pair of bearing seats, a shaft and a driving motor. The two bearing seats are respectively fixed on both sides of the upper end surface of the dipping tank. The shaft is rotatably installed on the two bearing seats. The rotating disk is fixedly mounted on the shaft. The driving motor is fixed on the side of one of the bearing seats, and the output shaft is fixedly connected to one end of the shaft.

[0009] Furthermore, a second bracket is fixed on the outer wall of the dipping pool, and an inclined feeding guide groove is fixed on the top of the second bracket. The bottom end of the feeding guide groove is correspondingly connected to the feeding part, and the top end of the feeding guide groove is connected to the discharge end of the vibrating screen plate.

[0010] Furthermore, a clearance gap is provided at the top of the side wall of the dipping pool away from the second bracket, and the clearance gap is higher than the coating liquid level in the dipping pool. A material discharge guide groove is obliquely installed in the clearance gap, and one end of the material discharge guide groove corresponds to the material discharge part, and the other end extends to the outer side of the dipping pool.

[0011] Furthermore, the bottom wall of the material discharge guide groove and the part located in the dipping pool are evenly distributed with drain holes that pass through from top to bottom, and a drainage outlet that passes through from top to bottom is provided on the bottom wall of the material discharge guide groove near the yield gap, and the two end walls of the drainage outlet are aligned with the inner walls on both sides of the material discharge guide groove one by one.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0013] 1. The utility model arranges temporary storage grooves at intervals in a circular array on a rotating disk. During the rotation of the rotating disk, the wire screw sleeve is loaded into the temporary storage groove at a loading portion, and after being dipped in a dipping pool by the adhesion of the paint, it is discharged at a discharging portion, thereby realizing rotary intermittent loading of the wire screw sleeve, avoiding the mutual interference and obstruction caused by the concentrated delivery of the wire screw sleeve. In addition, the wire screw sleeve can roll in the temporary storage groove blocked by the arc baffle, thereby ensuring uniform adhesion of the paint on its outer surface and improving the quality of the dipping process.

[0014] 2. When the utility model utilizes the feeding guide groove to feed the wire screw sleeve, the excess paint carried on the wire screw sleeve can be drained back into the dipping pool through the drain hole to achieve recycling and avoid excessive material loss.

[0022] In the embodiments of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0023] Please refer to Figures 1-4, A surface coating device for wire thread inserts provided by the utility model includes a dipping pool 1, a rotating disk 2, an arc-shaped baffle 3 and a driving mechanism 4. The arc-shaped baffle 3 is installed in the dipping pool 1 through a first bracket 301 arranged on the inner bottom wall of the dipping pool 1. A number of vertically penetrating through holes 302 are evenly distributed on the arc-shaped baffle 3 to ensure the up-and-down circulation of the coating. Both ends of the arc-shaped baffle 3 extend above the dipping pool 1, with one end being the loading part 31 and the other end being the unloading part 32. The rotating disk 2 is installed above the arc-shaped baffle 3 through a driving mechanism 4 arranged on the dipping pool 1. The outer edge wall of the rotating disk 2 is slidably and fittingly attached to the inner edge wall of the arc-shaped baffle 3. A number of temporary storage grooves 21 for accommodating wire thread inserts are arranged in a circular array around its axis on the outer edge wall of the rotating disk 2, and the driving mechanism 4 is used to drive the rotating disk 2 to rotate.

[0024] When using this device to dip-coat the wire thread inserts, the driving mechanism 4 works to drive the rotating disk 2 to rotate. When the temporary storage groove 21 rotates to the loading part 31, the wire thread inserts are loaded into it. As the rotating disk 2 continues to rotate, the arc-shaped baffle 3 blocks the temporary storage groove 21 with the wire thread inserts loaded inside to prevent the wire thread inserts from falling. At the same time, the coating passes through the through holes 302 and adheres to the wire thread inserts, realizing the dip-coating process of the wire thread inserts. As the rotating disk 2 continues to rotate, the temporary storage groove 21 carries the dip-coated wire thread inserts to move to the unloading part 32 for unloading.

[0025] This device arranges the temporary storage grooves 21 at intervals in a circular array on the rotating disk 2. During the rotation of the rotating disk 2, the wire thread inserts are loaded into the temporary storage grooves 21 at the loading part 31, and after being dip-coated by the attachment of the coating in the dipping pool 1, they are unloaded and discharged at the unloading part 32, realizing the rotary intermittent loading of the wire thread inserts, avoiding the mutual collision and blocking caused by the concentrated placement of the wire thread inserts. In addition, the wire thread inserts can roll in the temporary storage grooves 21 blocked by the arc-shaped baffle 3, thereby ensuring the uniform attachment of the coating on its outer surface and improving the quality of the dip-coating process.

[0026] Specifically, as the rotating disk 2 rotates, when the temporary storage groove 21 moves to correspond to the position of the loading part 31, its opening is inclined upward, facilitating the wire thread inserts to roll into the temporary storage groove 21 at the loading part 31. When the temporary storage groove 21 moves to correspond to the position of the unloading part 32, its opening is inclined downward, facilitating the wire thread inserts to roll out of the temporary storage groove 21 at the unloading part 32.

[0027] Specifically, the driving mechanism 4 includes a pair of bearing seats 41, a shaft 42 and a driving motor 43. The two bearing seats 41 are respectively fixed on both sides of the upper end surface of the dipping tank 1. The shaft 42 is rotatably installed on the two bearing seats 41. The rotating disk 2 is fixedly mounted on the shaft 42. The driving motor 43 is fixed on the side of one of the bearing seats 41, and the output shaft is fixedly connected to one end of the shaft 42. When the driving motor 43 works, its output shaft drives the shaft 42 to rotate, and then drives the rotating disk 2 to rotate, providing drive for the rotation of the rotating disk 2.

[0028] Specifically, a second bracket 51 is fixed on the outer wall of the dipping pool 1, and an inclined feeding guide groove 5 is fixed on the top of the second bracket 51. The bottom end of the feeding guide groove 5 corresponds to the feeding part 31, and the top end of the feeding guide groove 5 is connected to the discharge end of the vibrating screen plate. The vibrating screen plate is used to load the wire screw sleeve into the feeding guide groove 5, and the wire screw sleeve rolls downward in the feeding guide groove 5 to the feeding part 31. When the temporary storage groove 21 corresponds to the position of the feeding part 31, it rolls into the temporary storage groove 21 to realize the loading of the wire screw sleeve.

[0029] Specifically, a clearance gap 11 is provided at the top of the side wall of the dipping pool 1 away from the second bracket 51, and the clearance gap 11 is higher than the coating liquid level in the dipping pool 1. A material discharge guide groove 6 is obliquely installed in the clearance gap 11, and one end of the material discharge guide groove 6 corresponds to the material discharge portion 32, and the other end extends to the outer side of the dipping pool 1. When the position of the temporary storage groove 21 is aligned with the position of the material discharge portion 32, the wire screw sleeve in the temporary storage groove 21 rolls out onto the material discharge guide groove 6 and rolls downward along the material discharge guide groove 6 to realize material discharge.

[0030] Specifically, the bottom wall of the material discharge guide groove 6 and the part located in the dipping pool 1 are evenly distributed with drain holes 61 which penetrate up and down, so that the excess paint carried on the wire screw sleeve can be drained back into the dipping pool 1 to avoid excessive loss of materials. A drain port 62 which penetrates up and down is provided on the bottom wall of the material discharge guide groove 6 near the yielding notch 11, and the two end walls of the drain port 62 are aligned with the inner walls on both sides of the material discharge guide groove 6 one by one, so that the paint flowing along the inner wall of the material discharge guide groove 6 can be drained back into the dipping pool 1 to avoid excessive waste caused by the paint flowing out of the dipping pool 1 along the inner wall of the material discharge guide groove 6.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
