Description

Technical Field

[0001] This utility model relates to the field of arc spraying technology, and in particular to a wire pressing mechanism for an arc spray gun. Background Technology

[0002] Existing wire pressing mechanisms involve manually rotating a wire pressing rod to press the wire into a fork-shaped bracket, thus clamping the wire material with the wire pressing wheel. This mechanism requires opening the spray gun cover every time wire is pressed or released (due to the severe dust pollution from arc spraying, the mechanism must be isolated from the outside environment). Opening the spray gun cover each time is cumbersome, and workers may even forget to close it. This can damage the cover and contaminate the wire feeding mechanism, affecting its lifespan. In severe cases, it can even cause the spray gun to short-circuit and burn out completely. Utility Model Content

[0003] To solve the above problems, this technical solution provides a wire pressing mechanism for an arc spray gun.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A wire pressing mechanism for an electric arc spray gun includes:

[0006] The input section and the output section are located on both sides of the main body, respectively. The metal wire enters from the input section, is processed, and is discharged from the output section.

[0007] A wire feeding wheel, located between the input section and the output section, is used to drive the metal wire to move;

[0008] The wire pressing mechanism, located between the input section and the output section, includes a pressing rod rotatably disposed within the main body. One end of the pressing rod is provided with a pressing wheel for pressing the metal wire onto the wire feeding wheel. Another end of the pressing rod is also provided with an adjustment mechanism for adjusting the pressing degree of the pressing wheel. The other end is provided with a drive mechanism for driving the pressing rod to lift.

[0009] In some embodiments, the drive mechanism includes;

[0010] The adjusting screw has its operating end located outside the main body, and its other end passing through the main body and contacting the pressure rod.

[0011] In some embodiments, the adjustment mechanism includes;

[0012] The adjusting screw is located inside the main body and can move up and down within the main body;

[0013] The top rod has one end in contact with the pressure rod, and the other end is connected to the adjusting screw via a spring.

[0014] In some embodiments, a sleeve is further included for the adjustment screw to move within the body, and the push rod extends through the sleeve and contacts the pressure rod.

[0015] In some embodiments, the output sections are symmetrically arranged on both sides of the main body to perform dual-station operation.

[0016] In some embodiments, the input section has two wire-threading channels corresponding to the two output sections.

[0017] In some embodiments, the main body is provided with the wire feeding wheels on both sides, and a linkage shaft is provided between the two wire feeding wheels. The main body also includes a driver for driving the linkage shaft.

[0018] The beneficial effects of this application are:

[0023] Figure 3 This is a schematic diagram of the structure of an embodiment of the present utility model. Figure 3 . Detailed Implementation

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please refer to Figure 1-3 As shown, a wire pressing mechanism for an electric arc spray gun includes:

[0026] The input section 1 and the output section 2 are located on both sides of the main body, respectively. The metal wire enters from the input section 1, is processed, and is discharged from the output section 2.

[0027] The wire feeding wheel 3 is located between the input part 1 and the output part 2, and is used to drive the metal wire to move.

[0028] The wire pressing mechanism is located between the input section 1 and the output section 2. It includes a pressing rod 4 rotatably disposed in the body. One end of the pressing rod 4 is provided with a pressing wheel 5 for pressing the metal wire onto the wire feeding wheel 3. One end of the pressing rod 4 is also provided with an adjustment mechanism for adjusting the pressing degree of the pressing wheel 5. The other end is provided with a drive mechanism for driving the pressing rod 4 to lift.

[0029] Existing wire pressing mechanisms require manual rotation of the wire pressing rod and opening of the spray gun cover each time. This is inconvenient, and operators are prone to forgetting to close the cover, leading to damage to the cover and contamination of the wire feeding mechanism. Therefore, this application proposes a rotatable pressure rod hinged in the body. When the drive mechanism on the left moves upward, the adjustment mechanism on the right generates a downward force, causing the pressing wheel to firmly press the metal wire onto the wire feeding wheel. To remove the metal wire or thread it, the drive mechanism is moved downward, using a lever principle to move the pressure rod upward, moving the pressing wheel away from the wire feeding wheel and creating space for threading.

[0030] In this embodiment, the driving mechanism includes;

[0031] The adjusting screw 6 has its operating end located outside the main body, and its other end passes through the main body and contacts the pressure rod 4. Since the adjusting screw is threaded onto the main body, rotating the adjusting screw externally can push the pressure rod.

[0032] In this embodiment, the adjustment mechanism includes:

[0033] Adjusting screw 7 is located inside the main body and can move up and down inside the main body;

[0034] The top rod 8 has one end in contact with the pressure rod 4, and the other end is connected to the adjusting screw 7 via a spring 9.

[0035] During the above process, the spring is in a compressed state so that it always generates a force to push the top rod, which in turn pushes the pressure rod. The clamping force is changed by rotating the adjusting screw externally to change its vertical position.

[0036] In this embodiment, a sleeve 10 is also included for the adjustment screw 7 to be movably located within the body. After the push rod 8 passes through the sleeve 10, it contacts the pressure rod 4 to install the sleeve into the body. The adjustment screw is threaded inside the sleeve to change the position of the adjustment screw.

[0037] In this embodiment, the output section 2 is symmetrically arranged on both sides of the main body to perform dual-station operation. In one implementation, a metal wire passes through the input section to the output section on one side, and then through another metal wire to the output section on the other side. This process is repeated to achieve uninterrupted operation.

[0038] In this embodiment, the input section 1 is provided with two wire-threading channels 11 corresponding to the two output sections 2. In another embodiment, two metal wires are simultaneously threaded into the input section and then reach the corresponding wire-pressing mechanism through the corresponding channels, which results in higher working efficiency.

[0039] In this embodiment, the main body is provided with the wire feeding wheel 3 on both sides, and a linkage shaft 12 is provided between the two wire feeding wheels 3. It also includes a driver 13 for driving the linkage shaft 12, so as to realize the motor driving two machines and ensure that the working efficiency of both sides is consistent.

[0040] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
