Description

Technical Field

[0001] This utility model belongs to the field of shot blasting machine technology, and in particular relates to a quantitative feeding structure for shot blasting machines. Background Technology

[0002] Shot blasting machines are a common type of processing equipment. They mainly use high-speed shot thrown by a shot blaster to clean or strengthen the surface of castings. The machine can process a large number of castings at once. After processing, the castings are unloaded, which is where the unloading mechanism of the shot blasting machine comes in.

[0003] Traditional shot blasting machines typically use a spiral auger to transport shot into the shot blaster for blasting. This method makes it difficult to control the stable supply of shot during the shot blasting process, resulting in either too much or too little shot, which directly affects the efficiency and effect of shot blasting. Too much shot leads to waste, while too little shot affects the material processing effect. Therefore, we propose a quantitative feeding structure for shot blasting machines. Utility Model Content

[0004] The purpose of this utility model is to provide a quantitative feeding structure for shot blasting machines. By setting a quantitative part, specifically, the shot is placed into a storage tank. The resulting gravity is pressed onto a weighing device through a fixing ring, thereby determining the required amount of shot. By adjusting the amount, too much or too little shot is avoided, ensuring the efficiency and effect of shot blasting. Furthermore, sealing the bottom of the storage tank with a sealing ring improves the weighing accuracy. This solves the problem that traditional shot blasting machines usually use a spiral auger to transport shot into the shot blaster for blasting. This method makes it difficult to control the stable supply of shot during shot blasting, resulting in too much or too little shot, which directly affects the efficiency and effect of shot blasting.

[0034] 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 scope of protection of the present utility model.

[0035] Please see Figures 1-5 As shown, this utility model is a quantitative feeding structure for a shot blasting machine, including a shot blaster 1, a weighing device 11 arranged on the left side of the shot blaster 1, a support 12 installed at the bottom of the weighing device 11, and connecting plates 13 fixedly connected to both the front and back of the shot blaster 1. It also includes:

[0036] Metering unit 2, mounted above the weighing device 11, is used to quantitatively add pellets; and

[0037] Feeding section 3 is installed at the bottom of weigher 11 and is used to feed the pellets into shot blaster 1.

[0038] The shot blaster 1 is used to accelerate the shot to the required speed and launch it by high-speed rotation, and the support 12 is fixedly connected to the surface of the shot blaster 1 on the side facing the shot blaster 1.

[0039] The quantitative unit 2 includes a storage tank 21 located on top of the weighing device 11, with a fixing ring 22 fixedly connected to the bottom of the storage tank 21. When the pellets are placed into the storage tank 21, the resulting gravity will press onto the weighing device 11 through the fixing ring 22, thereby weighing and determining the required amount of pellets. By adjusting the amount, too much or too little pellets are avoided, ensuring the efficiency and effect of shot blasting. Furthermore, the bottom of the storage tank 21 is sealed by the sealing ring 234, which can improve the weighing accuracy.

[0040] A sealing assembly 23 is installed inside the storage tank 21 and is used to open and close the bottom of the storage tank 21.

[0041] The discharge pipe at the bottom of the storage tank 21 passes through the shot blaster 1 and extends to the feed section 3. The bottom of the fixing ring 22 contacts the top of the weighing device 11. When shot is added to the storage tank 21, the resulting gravity will press the weighing device 11 through the fixing ring 22.

[0042] The sealing assembly 23 includes a bracket 231 fixedly connected to the inner wall of the storage tank 21. An electric push rod 232 is fixedly connected to the top of the bracket 231. A connecting rod 233 is fixedly connected to the output end of the electric push rod 232. A sealing ring 234 is fixedly connected to the bottom of the connecting rod 233. Several slots 235 are opened inside the sealing ring 234.

[0043] When the sealing ring 234 moves upward, it opens the bottom of the storage tank 21; when the sealing ring 234 moves downward, it seals the bottom of the storage tank 21.

[0044] The feeding section 3 includes a feeding pipe 31 fixedly connected to the left side of the shot blaster 1, a motor 32 fixedly connected to the left side of the feeding pipe 31, and a conical ring 311 fixedly connected to the inner wall of the feeding pipe 31; and

[0045] Adjustment component 33 is installed inside the feed pipe 31 and is used to adjust the flow rate of pellets;

[0046] Among them, the discharge pipe at the bottom of the storage tank 21 extends into the inside of the feed pipe 31, and the right side of the feed pipe 31 is connected to the left side of the shot blaster 1 through a flange.

[0047] The adjustment assembly 33 includes a turntable 331 fixedly connected to the output end of the motor 32. A lifting frame 332 is provided on the right side of the turntable 331. A vertical rod 333 is fixedly connected to the bottom of the lifting frame 332. An adjusting plug 334 is fixedly connected to the bottom of the vertical rod 333. A sliding groove 335 is opened inside the lifting frame 332. A push shaft 336 is fixedly connected to the right side of the turntable 331. A limit rod 337 is slidably connected to the outside of the vertical rod 333. When the motor 32 is started, the turntable 331 is driven to rotate slowly. The push shaft 336 will push the lifting frame 332 up or down. At this time, the lifting frame 332 will drive the adjusting plug 334 to move up or down through the vertical rod 333, controlling the gap between the adjusting plug 334 and the conical ring 311. Different pellet flow rates can be adjusted according to different needs.

[0048] Among them, the back of the limiting rod 337 is fixedly connected to the inside of the feed pipe 31, the push shaft 336 is slidably connected to the inside of the slide groove 335, and the bottom of the adjusting plug 334 is adapted to the top of the conical ring 311.

[0049] The push shaft 336 slides within the slide groove 335 without affecting the rotation of the turntable 331 that drives the push shaft 336. The limiting rod 337 is used to limit the vertical rod 333, so that the vertical rod 333 drives the adjusting plug 334 to move up and down in a straight line.

[0050] The storage tank 21 has two fixed blocks 211 fixedly connected to both the front and back. The bottom of the fixed block 211 is fixedly connected to a limiting slide rod 212. The limiting slide rod 212 slides through the connecting plate 13 and cooperates with the connecting plate 13 to limit the storage tank 21.

[0051] One specific application of this embodiment is:

[0052] In use, pellets are placed into the storage tank 21. At this time, the sealing ring 234 is in a sealed state of the storage tank 21. After the pellets are added into the storage tank 21, the resulting gravity will press on the weighing device 11 through the fixing ring 22, thereby weighing. The limiting slide rod 212 slides on the connecting plate 13 to limit the storage tank 21 and prevent the storage tank 21 from shifting or shaking. The weighing device 11 weighs the pellets stored in the storage tank 21 to determine the required amount of pellets. By adjusting the amount, too much or too little pellets are avoided. After the addition is completed, the electric push rod 232 is started to drive the connecting rod 233 to move the sealing ring 234 upward, so the slot 235 is opened and the pellets are discharged from the slot 235 into the feed pipe 31 and transported to the shot blaster 1. The shot blaster 1 accelerates the shot to the required speed through high-speed rotation and throws it out.

[0053] Furthermore, during the shot blasting process, the starter motor 32 drives the turntable 331 to rotate slowly, and the push shaft 336 will rotate along with it, pushing the lifting frame 332 up or down. At this time, the lifting frame 332 will drive the adjusting plug 334 to move up or down through the vertical rod 333. The vertical rod 333 slides on the limit rod 337, causing the vertical rod 333 to drive the adjusting plug 334 to move in a linear manner. By adjusting the height of the adjusting plug 334, the gap between the adjusting plug 334 and the conical ring 311 can be controlled. When the gap is larger, the shot flow rate is larger and the shot blasting volume is larger. When the gap is smaller, the shot flow rate is smaller and the shot blasting volume is smaller. Different flow rates can be adjusted according to different needs.
