Description

Technical Field

[0001] This utility model belongs to the field of sandblasting machine technology, and in particular relates to an adjustable spray nozzle structure for use in automatic sandblasting machines. Background Technology

[0002] In industries such as metal surface treatment, casting cleaning, and shipbuilding, automatic sandblasting machines have become key equipment for improving production efficiency and ensuring uniform processing quality.

[0003] Chinese patent CN2568231Y discloses an adjustable spray angle nozzle, comprising a nozzle body with a centrally located spray hole. The lower part of the nozzle body is spherical, and a locking nut is provided on the upper part of the spherical body to mate with the spherical surface. A nozzle seat is provided on the lower part of the spherical body to mate with the spherical surface. The locking nut and the nozzle seat are threadedly connected, and the nozzle body is secured to the nozzle seat. The spray port, which connects to the spray hole, can be located on the side or top of the nozzle body.

[0004] As shown above, the device adopts a design structure in which the nozzle seat is connected by a locking nut thread and the nozzle body is clamped by a spherical fit. This allows the spray angle of the nozzle to be easily adjusted after installation, increasing the flexibility of nozzle use and providing convenience for nozzle installation. However, it does not allow for easy changes in spray mode, which is a limitation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable spray nozzle structure for use in automatic sandblasting machines, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable spray nozzle structure applied to an automatic sandblasting machine, including a support plate, two fixed plates fixedly connected to the bottom of the support plate, an adjustment mechanism provided inside the support plate, and an adjustment mechanism provided on the support plate; The adjusting mechanism is rotatably connected to a nozzle on one side of two fixed plates that are close to each other. A pipe is fixedly connected to the inner wall of the nozzle, and an axially movable sleeve is slidably connected to the outer wall of the pipe. A rack is fixedly connected to the top of the axially movable sleeve. A rotating shaft is rotatably connected to the inner wall of the nozzle, and a gear is fixedly connected to the rotating shaft. The outer wall of the gear meshes with the outer wall of the rack. A first knob is fixedly connected to one side of the rotating shaft, and a locking component is provided on the first knob.

[0007] Preferably, the locking assembly includes a first telescopic rod fixedly connected to the outer wall of the nozzle, a circular block fixedly connected to the outer wall of the first telescopic rod, and a first spring fixedly connected to the outer wall of the circular block.

[0008] Preferably, the end of the first spring away from the circular block is fixedly connected to the outer wall of the nozzle, the first telescopic rod is located inside the first spring, the outer wall of the circular block is rotatably connected to a first fixing block, the outer wall of the first fixing block is fixedly connected to a first locking block, and the first knob has a limiting hole adapted to the first locking block inside.

[0009] Preferably, the adjustment mechanism includes a lead screw rotatably connected to the outer wall of the support plate, a movable rod threadedly connected to the outer wall of the lead screw, a slider rotatably connected to the outer wall of the movable rod, and a sliding frame slidably connected to the outer wall of the slider.

[0010] Preferably, the outer wall of the sliding frame is fixedly connected to the outer wall of the nozzle, the outer wall of the lead screw is fixedly connected to a second knob, the top of the support plate is fixedly connected to a second fixing block, the outer wall of the second fixing block is fixedly connected to a second telescopic rod, the outer wall of the second telescopic rod is fixedly connected to a second locking block, and the outer wall of the second locking block is slidably connected to the inner wall of the second fixing block.

[0011] Preferably, a second spring is fixedly connected to the inner wall of the second locking block, and the end of the second spring away from the second locking block is fixedly connected to the outer wall of the second fixing block, and the second telescopic rod is located inside the second spring.

[0012] This utility model has the following beneficial effects: 1. This adjustable spray nozzle structure, applied to an automatic sandblasting machine, involves pulling the first fixed block outward, which causes the first telescopic rod to stretch and compress the first spring. Then, rotating the first fixed block causes the first locking block on it to misalign with the slot of the first knob to release the lock. At this time, the first knob can be manually rotated, which drives the gear to rotate through the rotating shaft, thereby driving the meshing rack to move linearly. Finally, the axial moving sleeve slides along the axial direction of the pipe to switch the spraying mode. After adjustment, pulling the first fixed block outward again and rotating it causes the first locking block to align with the slot of the first knob and then release it. The restoring force of the first spring will pull the first fixed block back to its original position, causing the first locking block to automatically engage with the first knob and lock its rotation angle, ensuring the stability of the selected spraying mode during operation.

[0013] 2. This adjustable spray nozzle structure, applied to an automatic sandblasting machine, allows for angle adjustment by pressing the second locking block. This block overcomes the spring force of the second spring, slides within the second fixed block, and presses against the second telescopic rod, disengaging the second locking block from the second knob and releasing its rotational limit. The second knob can then be manually rotated, directly driving the lead screw to rotate. The screw's rotation is converted into linear movement of the moving rod via a threaded joint, causing the slider to slide within the sliding frame, thus changing the nozzle's spray angle. After adjusting to the desired angle, releasing the second locking block allows the spring force of the second spring to automatically reset the second locking block, re-engaging it into the second knob surface. This mechanically locks the knob's rotational position, maintaining the set spray angle and preventing angle deviation due to vibration or external force during operation.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides two technical solutions: Figures 1-5 The first embodiment is shown: it includes a support plate 1, with two fixing plates 101 fixedly connected to the bottom of the support plate 1. The fixing plates 101 are symmetrically arranged to provide a stable and symmetrical installation base for the nozzle assembly. An adjustment mechanism 2 is provided inside the support plate 1, and an adjustment mechanism 3 is provided on the support plate 1. The adjusting mechanism 2 is rotatably connected to the nozzle 201 on one side of the two fixed plates 101 that are close to each other. This rotatable connection design allows the overall angle of the nozzle 201 to be adjusted by the subsequent adjusting mechanism 3. A pipe 202 is fixedly connected to the inner wall of the nozzle 201, and an axially movable sleeve 203 is slidably connected to the outer wall of the pipe 202. The axially movable sleeve 203 can slide along the axial direction of the pipe 202, and its front end position directly determines the divergence or convergence pattern of the jet flow, thereby realizing the switching of the spray mode. The top of the axially movable sleeve 203 is fixedly connected to... The nozzle 201 has a rack 204 and a rotating shaft 205 rotatably connected to its inner wall. A gear 206 is fixedly connected to the rotating shaft 205. The outer wall of the gear 206 meshes with the outer wall of the rack 204. Through the meshing of the gear 206 and the rack 204, the rotational motion of the rotating shaft 205 is precisely converted into the linear displacement of the axial moving sleeve 203. A first knob 207 is fixedly connected to one side of the rotating shaft 205. The first knob 207 serves as an external operation interface, allowing the user to manually drive the rotating shaft 205 to rotate. A locking component is provided on the first knob 207.

[0020] The locking assembly includes a first telescopic rod 208 fixedly connected to the outer wall of the nozzle 201. The first telescopic rod 208 provides guidance and support for the locking action. A round block 209 is fixedly connected to the outer wall of the first telescopic rod 208. A first spring 210 is fixedly connected to the outer wall of the round block 209. The first spring 210 provides a continuous holding force for the locked state.

[0021] The end of the first spring 210 away from the circular block 209 is fixedly connected to the outer wall of the nozzle 201. The first telescopic rod 208 is located inside the first spring 210. The outer wall of the circular block 209 is rotatably connected to the first fixing block 211. The rotatable connection allows the first fixing block 211 to rotate around the circular block 209 when unlocked, so as to avoid the first knob 207. The outer wall of the first fixing block 211 is fixedly connected to the first locking block 212. The first knob 207 has a limiting hole that matches the first locking block 212. The cooperation between the first locking block 212 and the limiting hole constitutes a mechanical lock on the rotation angle of the first knob 207, ensuring that the spraying mode will not be changed accidentally during operation.

[0022] When the spray mode needs to be adjusted, simply pull the first fixed block 211 outwards, which will stretch the first telescopic rod 208 and the first spring 210. Then rotate the first fixed block 211 so that the first locking block 212 is not aligned with the first knob 207. At this time, manually rotate the first knob 207 to drive the rotating shaft 205 to rotate, which in turn drives the gear 206 to rotate. When the gear 206 rotates, it will drive the rack 204 to move, which will drive the axial moving sleeve 203 to change its position on the pipe 202, thereby changing the spray mode. After the change is completed, simply pull the first fixed block 211 outwards to stretch the first telescopic rod 208 and the first spring 210. Then rotate the first fixed block 211 so that the first locking block 212 is aligned with the first knob 207. Then release it. At this time, the tension of the first spring 210 will pull the first fixed block 211 to move, so that the first locking block 212 is engaged in the first knob 207, fixing the rotation angle of the first knob 207.

[0023] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that the adjustment mechanism 3 includes a lead screw 301 rotatably connected to the outer wall of the support plate 1. A movable rod 302 is threadedly connected to the outer wall of the lead screw 301. A slider 303 is rotatably connected to the outer wall of the movable rod 302. The rotatable connection allows the slider 303 to swing adaptively within a certain angle to smoothly transmit linear thrust. A sliding frame 304 is slidably connected to the outer wall of the slider 303. The sliding frame 304 provides a precise linear track for the movement of the slider 303 and constrains its direction of movement.

[0024] The outer wall of the sliding frame 304 is fixedly connected to the outer wall of the nozzle 201. The linear motion of the slider 303 within the sliding frame 304 is directly converted into the pitch rotation of the nozzle 201 around its connection point with the fixed plate 101, thereby achieving the adjustment of the spray angle. A second knob 305 is fixedly connected to the outer wall of the lead screw 301. The second knob 305 serves as an external adjustment interface for manually driving the lead screw 301 to rotate. A second fixing block 306 is fixedly connected to the top of the support plate 1. The second fixing block 306 serves as the mounting base for the angle locking component. A second telescopic rod 307 is fixedly connected to the outer wall of the second fixing block 306. A second locking block 308 is fixedly connected to the outer wall of the second telescopic rod 307. The second telescopic rod 307 provides a stable guide for the pressing and resetting motion of the second locking block 308. The outer wall of the second locking block 308 is slidably connected to the inner wall of the second fixing block 306. The slidable connection ensures that the second locking block 308 can only move linearly in a preset direction, preventing it from deviating or getting stuck.

[0025] A second spring 309 is fixedly connected to the inner wall of the second locking block 308. The end of the second spring 309 away from the second locking block 308 is fixedly connected to the outer wall of the second fixing block 306. The second telescopic rod 307 is located inside the second spring 309. This arrangement ensures that the second spring 309 always applies a force to the second locking block 308, causing it to pop outward, thereby achieving the locking function of pressing to unlock and releasing to automatically reset. Under the action of the spring force, the second locking block 308 can be engaged with the side of the second knob 305 to lock its rotation position, thereby fixing the current spray angle of the nozzle 201.

[0026] When the spray angle needs to be adjusted, simply press the second locking block 308 so that it no longer limits the second knob 305. When the second locking block 308 is pressed, it will compress the second telescopic rod 307 and the second spring 309, causing the second locking block 308 to slide inside the second fixed block 306. Then, manually rotate the second knob 305 to drive the lead screw 301 to rotate. When the lead screw 301 rotates, it will drive the moving rod 302 to move, which in turn will drive the slider 303 to slide in the sliding frame 304, thereby changing the spray angle of the nozzle 201. When the angle is adjusted, release the second locking block 308. At this time, the elastic force of the second spring 309 will push the second locking block 308 back onto the second knob 305 to limit it.
