Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a through-type shot blasting machine with a shot blaster that can be quickly loaded and unloaded. Background Technology

[0002] Through-feed shot blasting machine is a mechanical device that uses high-speed projectiles (such as steel shot, iron shot, etc.) to clean, strengthen or treat the surface of workpieces. When working, the workpiece is fed into the shot blasting chamber by a conveyor device. The shot blaster rotates at high speed and accelerates the projectiles out to impact the workpiece surface to remove impurities and achieve surface treatment. The projectiles are recovered, separated and recycled. The dust generated is purified by a dust removal system. The whole process is continuous and efficient, enabling batch processing of workpieces.

[0003] Referring to the patent document: Patent Publication No. CN206014244U, Patent Publication Date 2017-03-15, a quick-loading and unloading device for shot blasting machines is disclosed, relating to the shot blasting production of bar (round steel) in the steel industry. The device includes a balance beam, with a counterweight positioning device at one end and a lifting lug welded to the middle, and a shot blasting device connecting device at the other end. The counterweight positioning device includes a counterweight positioning pin and a counterweight block. The counterweight positioning pin is welded to the balance beam, and the counterweight block is nested on the counterweight positioning pin. The shot blasting device connecting device includes a fixing pin, a rotating connecting rod, and a shot blasting device connecting plate. This device allows for quick replacement of faulty shot blasting devices during production, reducing manpower and ensuring on-site safety. It is a fast and effective specialized replacement tool. The quick replacement of shot blasting devices effectively improves the production efficiency of steel shot blasting and has significant economic benefits.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Currently, the traditional connection between shot blasting equipment and the main body of the shot blasting machine mostly relies on flange connection: it requires manual and precise alignment of the mounting holes, then bolting and tightening the nuts. The operation process is cumbersome, especially for large shot blasting equipment. Aligning the mounting holes is time-consuming and labor-intensive. Moreover, after long-term use, the nuts of the shot blasting equipment are prone to corrosion or the vibration principle can make the installation more secure, making it more difficult for workers to turn the nuts during disassembly, or even impossible to remove the nuts. Direct cutting and disassembly are required, further reducing maintenance efficiency and consequently reducing the processing efficiency of the workpiece.

[0006] Therefore, this utility model provides a through-type shot blasting machine with a shot blasting device that can be quickly loaded and unloaded. Utility Model Content

[0007] To address the problems of traditional shot blasting machines relying on manual alignment of bolt holes for flange connection with the main body, which is cumbersome to install and prone to disassembly difficulties due to rust or vibration, sometimes even requiring cutting and removal, seriously affecting maintenance efficiency and processing capacity; the purpose of this utility model is to provide a through-type shot blasting machine with a shot blasting unit that can be quickly loaded and unloaded.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a through-type shot blasting machine with a shot blasting device that can be quickly loaded and unloaded, comprising a shot blasting machine body, a shot blasting device body located at the top center of the shot blasting machine body, and a mounting mechanism located at the lower part of the shot blasting device body, the mounting mechanism comprising:

[0009] The fixing components include a mounting plate fixedly installed on the lower part of the shot blasting machine body. Two symmetrically distributed slots are opened on both sides of the mounting plate. Four symmetrically distributed bolts are rotatably installed on the top of the shot blasting machine body. The upper part of each of the four bolts is slidably locked in the middle of the slot. Nuts are threaded on the upper part of each of the four bolts. Anti-slip and shock-absorbing pads are fixedly installed on the bottom of the nuts. The bottom of the anti-slip and shock-absorbing pads are in contact with the top of the mounting plate.

[0010] The adjustment component, located at the lower part of the shot blasting machine body, allows for easy disassembly of the shot blasting machine body.

[0011] Preferably, the adjustment assembly includes an adjustment frame that is slidably mounted on the top center of the shot blasting machine body. Two symmetrically distributed double-headed screws are rotatably mounted on the upper part of the shot blasting machine body. Two symmetrically distributed moving blocks are threaded onto the upper part of each of the two double-headed screws. A support frame is rotatably mounted on the center of each of the moving blocks. The other end of each support frame is rotatably mounted on the lower sides of the adjustment frame.

[0012] Preferably, four evenly distributed positioning blocks are fixedly installed at the bottom of the mounting plate, and four evenly distributed positioning grooves are opened at the upper part of the adjustment frame, with the four positioning blocks slidably locked in the middle of the positioning grooves.

[0013] Preferably, the adjustment assembly further includes two worm gears rotatably mounted on the upper part of the shot blasting machine body. One end of each of the two double-ended screws is fixedly equipped with a worm wheel, and both worm wheels are meshed with the worm gears.

[0014] Preferably, the upper part of the shot blasting machine body has two symmetrically distributed moving grooves, and multiple moving blocks are slidably locked in the middle of the moving grooves.

[0015] Preferably, each pair of support frames is arranged with a narrower top and a wider bottom to form a scissor-type support structure, which can be used to adjust the height of the adjustment frame.

[0016] Beneficial effects

[0017] This invention provides a through-type shot blasting machine with a shot blasting device that can be quickly loaded and unloaded. Compared with the prior art, it has the following advantages:

[0018] 1. This application uses four rotatable bolts and nuts that can be installed on the shot blasting machine body to quickly fix the shot blasting device body. This solves the cumbersome process of installing the shot blasting device body on the shot blasting machine body, which requires aligning the mounting holes through a flange connection and then tightening the bolts through the mounting holes with nuts. The anti-slip and shock-absorbing pads can absorb the high-frequency vibrations generated during the operation of the shot blasting machine, preventing the bolts from loosening or being tightened too much, which would make it inconvenient to disassemble later.

[0019] 2. This application achieves height adjustment of the adjusting frame by driving the double-headed screw to rotate under the transmission of worm gear and worm shaft, thereby causing the two moving blocks to move in opposite directions. This reduces the frictional resistance generated when turning the nut during disassembly by lowering the height of the adjusting frame, making disassembly faster and easier.

[0026] 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.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a through-type shot blasting machine with a shot blasting device that can be quickly loaded and unloaded, including a shot blasting machine body 1, a shot blasting device body 11 located at the top center of the shot blasting machine body 1, and a mounting mechanism 2 located at the lower part of the shot blasting device body 11, the mounting mechanism 2 including:

[0028] The fixing component 21 includes a mounting plate 211 fixedly installed on the lower part of the shot blasting machine body 1. The mounting plate 211 is made of Q235B steel plate and is CNC machined, possessing good strength and flatness. Two symmetrically distributed slots 212 are provided on both sides of the mounting plate 211. The slots 212 have a U-shaped groove structure, with the groove width 0.5-1mm larger than the diameter of the bolt 215, facilitating quick insertion and removal of the bolt 215. The groove depth is 8mm to ensure axial stability after the bolt 215 is engaged. Four symmetrically distributed bolts 215 are rotatably installed on the top of the shot blasting machine body 1. The nuts 216 are made of nylon. The anti-loosening nut combines anti-loosening and shock absorption. The upper part of each of the four bolts 215 is slidably locked in the middle of the slot 212. Each of the four bolts 215 is threaded with a nut 216. The bottom end of the nut 216 is fixedly installed with an anti-slip and shock-absorbing pad 217. The bottom end of the anti-slip and shock-absorbing pad 217 is in contact with the top end of the mounting plate 211. The anti-slip and shock-absorbing pad 217 is made of nitrile rubber with a thickness of 5mm. Its surface is provided with cross anti-slip texture with a texture depth of 1mm. It can effectively absorb the high-frequency vibration of the shot blasting machine body 11 during operation and prevent the bolts 215 and nuts 216 from loosening due to continuous vibration.

[0029] Adjustment component 22 is located at the lower part of shot blasting machine body 11, which facilitates the disassembly of shot blasting machine body 11.

[0030] The adjustment assembly 22 includes an adjustment frame 221 that is slidably mounted on the top center of the shot blasting machine body 1. The adjustment frame 221 is made of aluminum alloy profiles, which is lightweight and strong enough to meet the support requirements. Two symmetrically distributed double-headed screws 224 are rotatably mounted on the upper part of the shot blasting machine body 1. Two symmetrically distributed moving blocks 223 are threaded on the upper part of each of the two double-headed screws 224. Support frames 222 are rotatably mounted on the middle of each of the multiple moving blocks 223. The other ends of the multiple support frames 222 are rotatably mounted on the lower sides of the adjustment frame 221.

[0031] Four evenly distributed positioning blocks 213 are fixedly installed at the bottom of the mounting plate 211. Four evenly distributed positioning grooves 214 are opened on the upper part of the adjusting frame 221. The four positioning blocks 213 are slidably locked in the middle of the positioning grooves 214. By locking the positioning blocks 213 in the positioning grooves 214, the mounting plate 211 can be positioned so that the slots 212 on the mounting plate 211 are aligned with the grooves on the adjusting frame 221, so as to facilitate fixing with bolts 215.

[0032] The adjustment assembly 22 also includes two worm gears 226 rotatably mounted on the upper part of the shot blasting machine body 1. One end of each of the two double-headed screws 224 is fixedly mounted with a worm wheel 225. Both worm wheels 225 are meshed with the worm gears 226. The structure of the worm wheel 225 and the worm gear 226 has a self-locking function, which can further limit the movement block 223 and prevent the double-headed screws 224 from rotating and causing the movement block 223 to move, resulting in a change in the height of the shot blasting machine body 11 and causing the shot blasting machine body 11 to loosen.

[0033] The upper part of the shot blasting machine body 1 has two symmetrically distributed moving grooves 2231. Multiple moving blocks 223 are slidably locked in the middle of the moving grooves 2231. The moving grooves 2231 can limit and guide the moving blocks 223, so that the two moving blocks 223 can move relative to each other or opposite to each other in the moving grooves 2231 through the screw drive under the rotation of the double-headed screw 224.

[0034] Each pair of support frames 222 is narrower at the top and wider at the bottom, forming an inward-facing octagonal structure. When their moving blocks 223 move in opposite directions, they can drive the lower ends of the two support frames 222 to move in opposite directions, thereby causing the upper part of the support frame 222 to move downward, forming a scissor-type support structure, which is used to adjust the height of its adjusting frame 221.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, the mounting plate 211 at the lower part of the shot blasting machine body 11 is brought into contact with the adjusting frame 221, and the positioning block 213 is slidably locked inside the positioning groove 214, thus completing the positioning of the mounting plate 211. On both sides of the adjusting frame 221, there are grooves corresponding to the slots 212 opened on both sides of the mounting plate 211. The grooves and slots 212 are aligned with each other. The operator flips the bolt 215 to keep it perpendicular to the mounting plate 211, and the bolt 215 is locked into the slots 212 and the groove. By rotating the nut 216, the anti-slip damping pad 217 moves downward synchronously, so that the anti-slip damping pad 217 comes into contact with the top of the mounting plate 211, thereby fixing the mounting plate 211, that is, fixing the upper shot blasting machine body 11.

[0037] During disassembly, the worm gear 226 is first rotated to drive the meshing worm wheel 225 to rotate, causing the double-headed screw 224 to rotate. This causes the two moving blocks 223 to slide in the moving groove 2231 and move in opposite directions, causing the lower part of the support frame 222 inside to move to both sides. This, in turn, causes the adjusting frame 221 to move downward, so that under the action of gravity, the shot blasting body 11 moves downward synchronously. This prevents the top of the mounting plate 211 from contacting the bottom of the anti-slip damping pad 217. Then, the nut 216 can be quickly rotated upward without friction to move it a certain distance. After that, the bolt 215 is flipped so that it is level with the mounting plate 211. At this time, the bolt 215 is disengaged from the slot 212, thus completing the disassembly task.
