Description

Technical Field

[0001] This utility model relates to the technical field of rod extracting machine equipment, and in particular to an automatic feeding device for rod extracting machine. Background Technology

[0002] When precision machining sapphire crystal rods, specialized rod-scooping machines are usually required. These machines can efficiently process the rods into hollow tubular structures of specific diameters and lengths while ensuring the integrity of the internal structure and the smoothness of the surface. During the operation of the rod-scooping machine, it is necessary to ensure its stable movement.

[0003] The traditional lead screw drive is used for feeding rod extraction machines. When the lead screw drives the rod extraction machine to move forward, there is a rigid contact between the rod extraction machine and the sapphire material. The impact force under the rigid contact can easily form fine scratches on its surface, which will affect the appearance quality of the sapphire products. To this end, we have provided an automatic feeding device for rod extraction machines. Utility Model Content

[0004] This invention provides an automatic feeding device for a sapphire extraction machine, which allows the machine to make flexible contact with the sapphire material during feeding, so as to avoid impact damage to the sapphire material and further improve the appearance quality of sapphire products.

[0005] The purpose and effect of this utility model of an automatic feeding device for a rod-scooping machine are achieved by the following specific technical means: An automatic feeding device for a rod-scooping machine includes a hanging plate and a rod-scooping machine body disposed below the hanging plate, and further includes:

[0006] The flexible feeding assembly is located between the hanging plate and the bar extractor body, including a mounting plate installed above the bar extractor body, a set of sliding columns located above the mounting plate, a piston cylinder slidably connected to the outside of each sliding column, and a propulsion structure located below the hanging plate for the sliding columns to push the bar extractor body for flexible feeding.

[0007] The guide components are located on the left and right sides of the rod-removing machine body to ensure the smooth lifting and lowering of the rod-removing machine body.

[0008] Preferably, the propulsion structure of the flexible feeding assembly includes an air pump installed on the bottom surface of the hanging plate, a T-shaped tube installed at the output end of the air pump, the two output ends of the T-shaped tube being connected to the inner top wall of the piston cylinder, and a piston plate adapted to the piston cylinder being installed at the top of each sliding column.

[0009] Preferably, each of the sliding columns has annularly arranged positioning grooves on its outer surface, and a positioning block is slidably connected to the inner wall of each positioning groove. The other end of each positioning block is connected to the inner wall of the piston cylinder.

[0010] Preferably, an arc-shaped plate is fixedly connected to the outer surface of each piston cylinder, and a set of L-shaped plates is fixedly connected to the back of each arc-shaped plate. The top of each L-shaped plate is connected to the bottom surface of the hanging plate.

[0011] Preferably, each piston cylinder is provided with a pressure relief valve on its exterior, and a reinforcing plate is fixedly connected to the outer surfaces of the two piston cylinders. A sliding rod is slidably connected to the reinforcing plate, the bottom end of the sliding rod is connected to the upper surface of the mounting plate, a circular plate is fixedly connected to the top end of the sliding rod, and a return spring is sleeved on the outside of the sliding rod.

[0012] Preferably, the guide assembly includes a set of upright plates fixedly connected to the bottom surface of the hanging plate. Each of the two upright plates has a set of guide grooves on its side facing each other. Each guide groove has a guide block slidably connected to its inner wall. The two sets of guide blocks are respectively connected to the left and right sides of the mounting plate at their respective ends.

[0013] Preferably, each group of guide blocks has a guide wheel installed on one side that is close to each other, and each guide wheel is in contact with one side that is close to the upright plate.

[0016] Preferably, both the left and right sides of the hanging plate are fixedly connected with perforated fixing plates.

[0017] Beneficial effects:

[0018] 1. Through the flexible feeding component, the pressure of the gas can be used to push the bar extractor body to feed. When the bar extractor body comes into contact with the sapphire material, the gas is compressible and can form a flexible buffer in the piston cylinder, so that the bar extractor body does not make a rigid impact during feeding, so as to avoid impact force damaging the sapphire material and further improve the appearance quality of the sapphire products. Through the guide component, the movement of the bar extractor body can be precisely positioned and guided, effectively avoiding deviation and shaking during the movement of the bar extractor body.

[0019] 2. Through the cooperation of the pressure relief valve, reinforcing plate, slide bar, spring and circular plate, when the slide bar descends, it will drive the circular plate to compress the spring and generate elastic potential energy. When the bar extractor body is reset, the pressure relief valve is controlled to release pressure, and the spring will gradually extend and push the circular plate. The slide bar will then lift the bar extractor body upward through the mounting plate to quickly reset it, thus preparing it for the next processing. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] First Embodiment

[0030] As attached Figure 1 To be continued Figure 5As shown: An automatic feeding device for a rod extractor includes a hanging plate 1 and a rod extractor body 2 disposed below the hanging plate 1. A flexible feeding component 3 is disposed between the hanging plate 1 and the rod extractor body 2, including a mounting plate 301 installed above the rod extractor body 2, a set of sliding columns 302 disposed above the mounting plate 301, a piston cylinder 303 slidably connected to the outside of each sliding column 302, and a propulsion structure disposed below the hanging plate 1 for the sliding columns 302 to push the rod extractor body 2 for flexible feeding. The propulsion structure of the flexible feeding component 3 includes an air pump 304 installed on the bottom surface of the hanging plate 1. A T-shaped tube 305 is installed at the output end of the air pump 304. The two output ends of the T-shaped tube 305 are respectively connected to the inner top of the piston cylinder 303. The walls are connected, and each sliding column 302 is equipped with a piston plate 306 that matches the piston cylinder 303. When the air pump 304 is working, it will inflate the piston cylinder 303 through the T-shaped pipe 305. As the pressure at the top of the piston cylinder 303 gradually increases, the piston plate 306 will descend and move the sliding column 302. The sliding column 302 will then push the mounting plate 301 and the rod extractor body 2 to feed the sapphire material. When the rod extractor body 2 comes into contact with the sapphire material, due to the compressibility of the gas, a flexible buffer is formed in the piston cylinder 303. This makes the rod extractor body 2 make flexible contact with the sapphire material during feeding, so as to avoid impact force damaging the sapphire material and further improve the appearance quality of the sapphire product.

[0031] Each piston cylinder 303 is equipped with a pressure relief valve 311 on its exterior. The outer surfaces of the two piston cylinders 303 are fixedly connected to a reinforcing plate 312. A sliding rod 313 is slidably connected to the reinforcing plate 312. The bottom end of the sliding rod 313 is connected to the upper surface of the mounting plate 301. A circular plate 314 is fixedly connected to the top end of the sliding rod 313. A return spring 315 is sleeved on the outside of the sliding rod 313. As the mounting plate 301 descends, it will drive the sliding rod 313, and the circular plate 314 will squeeze the return spring 315. When it is necessary to adjust the rod extractor body 2 to reset, the pressure relief valve 311 is controlled to release pressure inside the piston cylinder 303. The return spring 315 will gradually extend and push the circular plate 314. The sliding rod 313 will lift the mounting plate 301 and the rod extractor body 2 upward, so that the rod extractor body 2 resets and prepares for the next operation.

[0032] Each sliding column 302 has annularly arranged positioning grooves 307 on its outer surface. Each positioning groove 307 has a positioning block 308 slidably connected to its inner wall. The other end of each positioning block 308 is connected to the inner wall of the piston cylinder 303. The cooperation between the positioning grooves 307 and the positioning blocks 308 can stabilize the sliding column 302 and the piston cylinder 303, ensuring stability when the sliding column 302 drives the piston plate 306 to descend. Each piston cylinder 303 has an arc-shaped plate 309 fixedly connected to its outer surface. Each arc-shaped plate 309 has a set of L-shaped plates 310 fixedly connected to its back. The top of each L-shaped plate 310 is connected to the bottom surface of the hanging plate 1. The L-shaped plates 310 and the arc-shaped plates 309 can stably suspend the piston cylinder 303 on the hanging plate 1, which can restrict the movement of the piston cylinder 303 in all directions, effectively resist the vibration and impact generated during equipment operation, and ensure that the piston cylinder 303 remains stable at all times.

[0033] Second Embodiment

[0034] As attached Figure 1 With appendix Figure 6 As shown: Guide assembly 4, located on the left and right sides of the rod-removing machine body 2, is used to ensure the smooth lifting and lowering of the rod-removing machine body 2. The guide assembly 4 includes a set of upright plates 401 fixedly connected to the bottom surface of the hanging plate 1. Each of the two upright plates 401 has a set of guide grooves 402 on its side facing each other. The inner wall of each guide groove 402 is slidably connected to a guide block 403. The two sets of guide blocks 403 are respectively connected to the left and right sides of the mounting plate 301. By using the cooperation of the guide blocks 403 and the guide grooves 402, the mounting plate 301 can be moved and guided, thereby ensuring that the mounting plate 301 drives the rod-removing machine body 2 to lift and lower stably. Each set of guide blocks 403 has a guide wheel 404 installed on its side facing each other. Each guide wheel 404 is in contact with the side of the adjacent upright plate 401. The guide wheel 404 reduces the frictional resistance when the guide block 403 moves, ensuring that the guide block 403 slides smoothly.

[0035] A set of U-shaped plates 405 are fixedly connected to the front of the two upright plates 401. The U-shaped plates 405 can be used to reinforce the connection between the upright plates 401, enhance the connection strength between the two upright plates 401, effectively prevent the upright plates 401 from relative displacement or deformation during equipment operation, and greatly improve the stability of guiding the main body 2 of the bar-removing machine. An inclined plate 406 is fixedly connected to the back of each upright plate 401. The top of each inclined plate 406 is connected to the bottom surface of the hanging plate 1. The inclined plate 406 can be used to connect the upright plate 401 and the hanging plate 1, further enhancing the firmness of the upright plate 401.

[0036] Third Embodiment

[0037] As attached Figure 1As shown: Based on the first and second embodiments, the left and right sides of the hanging plate 1 are fixedly connected with perforated fixing plates 5. The perforated fixing plates 5 can be used to fix the rod-removing machine body 2, the flexible feeding component 3 and the guide component 4.

[0038] Working principle: When the bar extractor body 2 is pushed forward, the air pump 304 is controlled to work. The air pump 304 will inflate the piston cylinder 303 through the T-shaped pipe 305. As the pressure at the top of the piston cylinder 303 gradually increases, the piston plate 306 will descend and move the slide column 302. The slide column 302 will push the mounting plate 301 and the bar extractor body 2 to feed the sapphire material. When the bar extractor body 2 comes into contact with the sapphire material, due to the compressibility of the gas, a flexible buffer is formed in the piston cylinder 303. This makes the bar extractor body 2 make flexible contact with the sapphire material during feeding, so as to avoid impact force damaging the sapphire material and further improve the appearance quality of the sapphire product.
