Description

Technical Field

[0001] This utility model proposes a calibration structure, which relates to the field of shot blasting machines, and specifically to a calibration structure for a pneumatic spray gun of a spherical shot blasting machine. Background Technology

[0002] The pellets are made by a spherical shot blasting machine. The spray gun atomizes the liquid binder into microdroplets of 30–80 μm using compressed air at 0.3–0.6 MPa, and sprays them evenly onto the surface of the wet particles rolling in the centrifuge disc. The liquid bridge force promotes the agglomeration of the particles into spheres.

[0003] The existing pneumatic spray gun uses an angle gauge to measure the angle between the spray gun and the rotation axis of the shot blasting chamber, and adjusts it to 30°-45° using gun frame bolts. Different materials, centrifugal speeds, and shot making requirements result in different settings for the height and angle of the pneumatic spray gun. The angle adjustment accuracy of the pneumatic spray gun using gun frame bolts is limited, and adjustment via bolts is also relatively troublesome. The anti-loosening structure of bolts that need to be adjusted frequently is also inconvenient, which is not conducive to continuous production.

[0004] Therefore, those skilled in the art propose a calibration structure for a pneumatic spray gun in a spherical shot blasting machine. For pneumatic spray guns that require angle adjustment, a calibration structure is designed that is faster and more convenient to adjust, and has higher accuracy. The calibration structure can also be anti-loosening and limited. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a calibration structure for a pneumatic spray gun for a spherical shot blasting machine. It features a nozzle structure that moves up and down along a mounting frame. The distance the nozzle travels along the mounting frame is transmitted to a lever via a protrusion and a push rod, causing the lever to move periodically and push a ratchet to change the nozzle's setting angle. It is equipped with universal adjustment for different situations, allowing for synchronous adjustment of the nozzle angle with changes in the nozzle's setting height. Alternatively, the nozzle angle can be adjusted independently via the ratchet, making it more convenient to use.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a calibration structure for a pneumatic spray gun of a spherical shot blasting machine, comprising a centrifuge cylinder and a nozzle disposed inside it. The nozzle is slidably disposed inside the centrifuge cylinder via a mounting bracket, and the nozzle is adjusted in height along the mounting bracket to correspond to different processing requirements.

[0007] A ratchet is fixed to the side of the nozzle. The ratchet drives the nozzle to adjust its angle. The nozzle angle can be adjusted by the ratchet alone, or the ratchet can be rotated synchronously by the nozzle moving along the mounting bracket.

[0008] A lever is provided on the same plane as the ratchet. As the nozzle moves along the mounting frame, it periodically pushes the lever to rotate, driving the ratchet in one direction. The distance the nozzle moves along the mounting frame is converted into rotational drive of the ratchet by the lever.

[0009] Preferably, the nozzle is slidably mounted along the mounting bracket via a slider, and the nozzle slidably connected to the mounting bracket via the slider facilitates adjustment of the installation angle.

[0010] The mounting bracket has protrusions fixed at equal intervals on the side near the nozzle. As the nozzle slides up and down along the mounting bracket, the lever on the side of the nozzle is driven by the protrusions to perform periodic movements.

[0011] A push rod is slidably provided on the side of the slider corresponding to the protrusion. The end of the push rod pushes the protrusion to advance, and the advancing push rod drives the lever to perform unidirectional periodic drive on the ratchet.

[0012] Preferably, a crankshaft is vertically arranged on the side of the slider, the end of the lever away from the ratchet is rotatably connected to the crankshaft, and the end of the push rod away from the mounting bracket is also rotatably connected to the crankshaft. The push rod is pushed by the protrusion, which drives the crankshaft to rotate in a fixed direction. The rotating crankshaft drives the periodic movement of the lever, thereby realizing the rotational drive of the ratchet at the end of the lever away from the crankshaft.

[0013] Preferably, a fixing block is fixed to the side of the lever and push rod away from the crankshaft, and a sliding groove is provided on the side of the slider, and the end of the lever and push rod away from the crankshaft is slidably connected to the slider through the sliding groove.

[0014] The end of the lever and push rod away from the crankshaft is guided along the slide groove by a fixed block. When the crankshaft rotates, the advance and angle change can occur simultaneously, thereby using the advance and deflection of the lever to drive the ratchet to rotate.

[0015] Preferably, a spring is provided on the side of the push rod to abut against it. After passing through the range of action of the protrusion, the spring helps to reset the ratchet drive structure so as to facilitate the continuous operation of the drive system.

[0016] The protrusion and the end of the push rod are respectively provided with wedge-shaped transition surfaces to ensure the pushing and squeezing driving effect of the protrusion on the push rod.

[0017] This utility model discloses a calibration structure for a pneumatic spray gun of a spherical shot blasting machine, which has the following beneficial effects:

[0018] The calibration structure of the pneumatic spray gun for this spherical shot blasting machine involves adjusting the installation height of the nozzle within the centrifuge tube via a mounting bracket. Simultaneously, changes in the nozzle's installation height are correlated with the movement of the nozzle along the mounting bracket. The number of protrusions fixed to the side of the mounting bracket drives a push rod periodically, which in turn drives a crankshaft to rotate. This crankshaft periodically drives a lever to advance and deflect, which in turn drives a ratchet at its end to rotate. This synchronizes the adjustment of the nozzle's installation height and deflection angle, allowing for rapid nozzle adjustment to a certain extent. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model discloses a calibration structure for a pneumatic spray gun of a spherical shot blasting machine;

[0027] According to the appendix Figure 1As shown, the existing technology of mounting the nozzle 2 on a gun mount is changed to a mounting structure in which the mounting bracket 3 is fixed on the inner wall of the centrifuge cylinder 1, and the nozzle 2 can be adjusted to a height on the inner side of the centrifuge cylinder 1 along the mounting bracket 3.

[0028] According to the appendix Figure 2 and attached Figure 3 As shown, a ratchet 4 is fixed to the side of the nozzle 2, and the installation angle of the nozzle 2 can be adjusted directly through the ratchet 4.

[0029] The nozzle 2 is slidably mounted to the mounting bracket 3 via the slider 6, facilitating the adjustment of the nozzle 2's setting angle. Additionally, a lever 5 is slidably mounted on the side of the slider 6, with one end of the lever 5 extending to the side of the ratchet 4. When the nozzle 2 is adjusted in height along the mounting bracket 3, the resulting displacement is converted into a reciprocating drive on the lever 5. The reciprocating motion of the lever 5 drives the ratchet 4 to rotate in a fixed direction. This allows the nozzle 2 to adjust its installation height along the mounting bracket 3 while simultaneously adjusting its installation angle. In some fixed applications, the installation height and angle of the nozzle 2 can be adjusted in one step.

[0030] According to the appendix Figure 3 As shown, the lamp fixing protrusion 7 on the side of the mounting bracket 3, while the nozzle 2 adjusts the installation height along the mounting bracket 3, measures the moving distance through the equally spaced protrusions 7, and the push rod 8 is slidably set on the side of the slider 6. The protrusion 7 pushes the push rod 8 to advance, and the advance of the push rod 8 drives the lever 5 to reciprocate.

[0031] A crankshaft 9 is provided on the side of the slider 6. One end of the lever 5 and the push rod 8 are rotatably connected to the crankshaft 9. When the push rod 8 is pushed by the protrusion 7, the crankshaft 9 is driven to rotate. The rotating crankshaft 9 drives the lever 5, which is rotatably connected to it, to complete the reciprocating motion.

[0032] According to the appendix Figure 3 and attached Figure 4 As shown, in order to ensure that the lever 5 reciprocates when driven by the crankshaft 9, the ratchet 4 can be driven to rotate in a directional manner. A fixing block 10 is fixedly installed on the side of the lever 5 near the ratchet 4. A sliding groove 11 is opened on the side of the slider 6 corresponding to the fixing block 10. The lever 5 is slidably installed along the sliding groove 11 through the fixing block 10. When one end of the lever 5 is driven by the crankshaft 9, the fixing block 10 is limited and guided by the sliding groove 11, so that the lever 5 completes the lateral advance and the longitudinal angle deflection in one motion cycle, which corresponds to the ratchet structure on the side of the ratchet 4, driving the ratchet 4 to deflect at a certain angle.

[0033] In addition, for the long-term use of the drive unit, a spring 12 structure is provided on the side of the push rod 8 to press against it. After the pushing action of the protrusion 7 is lost, the push rod 8 is reset under the elastic force of the spring 12. At the same time, the crankshaft 9 is also reset by the pull of the push rod 8, and the lever 5 moves backward.

[0034] The calibration structure of the pneumatic spray gun for the spherical shot blasting machine involves adjusting the installation height of the nozzle 2 within the centrifuge cylinder 1 via the mounting bracket 3. Simultaneously, the change in the installation height of the nozzle 2 is correlated with the movement distance of the nozzle 2 along the mounting bracket 3. The number of protrusions 7 fixed to the side of the mounting bracket 3 is used to periodically push the push rod 8, which drives the crankshaft 9 to rotate. The rotating crankshaft 9 periodically drives the lever 5 to advance and deflect, driving the ratchet 4 at its end to rotate. This synchronously adjusts the installation height and deflection angle of the nozzle 2, allowing for rapid adjustment of the nozzle 2 to a certain extent.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
