Description

Technical Field

[0001] This utility model relates to the field of cored wire processing technology, specifically a cored wire feeding device. Background Technology

[0002] Cored wire is made by wrapping alloy powder around a strip of steel. Depending on the type of alloy powder, it can be classified as: silicon-calcium cored wire, silicon-manganese-calcium cored wire, silicon-calcium-barium cored wire, barium-aluminum cored wire, aluminum-calcium cored wire, calcium-iron cored wire, pure calcium cored wire, etc. The wound appearance is similar to that of regular wire.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1 to 4 The core material feeding device of the cored wire in this embodiment includes a mixing cylinder 1, two hoppers 2 disposed on the top of the mixing cylinder 1, a connecting frame 3 fixedly connected to the outside of the mixing cylinder 1, and a driving mechanism 4 disposed on the outside of the mixing cylinder 1. The hopper 2 is provided with an anti-blocking structure 5 for preventing the core material from blocking, and the connecting frame 3 is provided with a transmission structure 6 for operating the anti-blocking structure 5.

[0027] The drive mechanism 4 includes a dual-axis motor 41, a transmission gear 42, a rotating sleeve 43, and a gear disc 44. The dual-axis motor 41 is fixedly installed inside the connecting frame 3. The transmission gear 42 is fixedly connected to the bottom output shaft of the dual-axis motor 41. The rotating sleeve 43 is rotatably connected to the inside of the mixing cylinder 1 and extends to its upper surface. The gear disc 44 is fixedly connected to the top of the rotating sleeve 43. Both hoppers 2 are fixedly installed inside the gear disc 44. The bottom of the hoppers 2 is fixedly connected to a feed pipe, and an on / off valve is fixedly installed inside the feed pipe. A pressure relief valve is fixedly installed on the back of the mixing cylinder 1. Its main function is to automatically regulate the air pressure inside the mixing cylinder 1 to ensure that the air pressure inside the mixing cylinder 1 is maintained within a safe and stable range. When the air pressure inside the mixing cylinder 1 exceeds the set value, the pressure relief valve will automatically open to release excess gas; when the air pressure drops to the normal range, the pressure relief valve will automatically close. By simultaneously driving the rotation of the hoppers 2 and the operation of the transmission structure 6 through the dual-axis motor 41, the equipment cost and energy consumption are reduced, while the synchronization and coordination of equipment operation are improved.

[0028] In this embodiment, the anti-clogging structure 5 includes connecting covers 51 detachably connected to the tops of the two hoppers 2, an I-shaped tube 52 fixedly installed inside the two connecting covers 51, an air outlet 53 opened on the lower surface of the I-shaped tube 52, and an inflation component disposed outside the connecting frame 3. By providing detachable connecting covers 51, it is convenient to clean and maintain the inside of the hopper 2, and it is also convenient to replace and repair anti-clogging components such as the I-shaped tube 52, reducing maintenance difficulty and cost.

[0029] The inflation assembly includes a piston cylinder 54 fixedly connected to the outside of the connecting frame 3, a stopper plate 55 slidably connected to the inside of the piston cylinder 54, a stopper rod 56 fixedly connected to the top of the stopper plate 55, and an air inlet pipe 57 and a delivery pipe 58 fixedly connected to the outside of the piston cylinder 54. The stopper rod 56 is slidably connected to the inside of the piston cylinder 54 and extends to its upper surface.

[0030] Specifically, the end of the delivery pipe 58 away from the piston cylinder 54 is rotatably connected to the top of the U-shaped tube 52 via a bushing 59, and a one-way valve is fixedly installed inside the delivery pipe 58.

[0031] In this embodiment, the transmission structure 6 includes a transmission shaft 61 fixedly connected to the top output shaft of the dual-axis motor 41, a fixed sleeve 62 fixedly connected to the top of the transmission shaft 61, a sliding sleeve 63 slidably connected to the outside of the transmission shaft 61, a connecting rod 64 hinged to the outside of the fixed sleeve 62, a flyball 65 hinged to the bottom of the connecting rod 64, a transmission plate 69 fixedly connected to the outside of the sliding sleeve 63, and a limiting component disposed outside the sliding sleeve 63. By utilizing the sliding of the flyball 65 under the action of centrifugal force to drive the sliding sleeve 63 to move, and then driving the inflation component to work through the transmission plate 69, this transmission method can automatically adjust the inflation amount according to the rotation speed of the hopper 2. When the rotation speed of the hopper 2 increases, the centrifugal force on the flyball 65 increases, and the inflation amount increases; when the rotation speed of the hopper 2 decreases, the inflation amount decreases, realizing automatic adjustment and improving the anti-clogging effect.

[0032] The transmission structure 6 comprises two sets of connecting rods 64 and two sets of flying balls 65, symmetrically distributed on the outside of the fixed sleeve 62 and the sliding sleeve 63. A return spring 68 is fixedly connected between the fixed sleeve 62 and the sliding sleeve 63, and is wound around the outside of the transmission shaft 61. By setting the return spring 68, the sliding sleeve 63 can be reset when the centrifugal force of the flying ball 65 decreases, ensuring the normal operation of the transmission structure 6 and improving the stability and reliability of the structure.

[0033] Specifically, the limiting component includes a limiting rod 66 fixedly connected to the outside of the sliding sleeve 63 and a baffle 67 fixedly connected to the end of the limiting rod 66 away from the sliding sleeve 63. The flying ball 65 is slidably connected to the outside of the limiting rod 66. By setting the limiting component, the sliding range of the flying ball 65 is limited, ensuring that the flying ball 65 moves on the specified track, and improving the accuracy and reliability of the transmission.

[0034] It should be noted that the end of the transmission plate 69 furthest from the sliding sleeve 63 is fixedly connected to the top of the plug rod 56, and a limiting shaft 610 extending to the upper surface of the transmission plate 69 is fixedly connected to the top of the connecting frame 3. The transmission plate 69 is slidably connected to the outside of the limiting shaft 610. The limiting shaft 610 guides the movement of the transmission plate 69, making the movement of the transmission plate 69 more stable and ensuring the normal operation of the inflation assembly.

[0035] In this embodiment, a stirring structure 7 is provided inside the mixing cylinder 1. The stirring structure 7 includes a stirring shaft 71 rotatably connected inside the mixing cylinder 1 and extending to its bottom, a stirring blade 72 fixedly connected to the outside of the stirring shaft 71, a connecting shaft 73 fixedly connected to the bottom of the transmission gear 42, a transmission wheel 74 fixedly connected to the bottom end of the connecting shaft 73, and a driven wheel 75 fixedly connected to the bottom end of the stirring shaft 71. A belt 76 is externally connected to the transmission wheel 74 and the driven wheel 75. A discharge pipe is fixedly connected to the bottom of the mixing cylinder 1, and a solenoid valve is fixedly installed inside the discharge pipe.

[0036] The working principle of the above embodiments is as follows:

[0037] In use, the core material is placed inside the hopper 2. The dual-shaft motor 41 is started by the controller. Its bottom output shaft drives the transmission gear 42 to rotate, which in turn drives the transmission wheel 74 to rotate via the belt 76. The transmission wheel 74 drives the connecting shaft 73 to rotate, which in turn drives the driven wheel 75 to rotate. The driven wheel 75 drives the stirring shaft 71 to rotate, and the stirring shaft 71 drives the stirring blades 72 to rotate inside the mixing drum 1. At the same time, the rotation of the bottom output shaft of the dual-shaft motor 41 also drives the rotating sleeve 43 to rotate. The rotating sleeve 43 drives the gear disc 44 to rotate, and the gear disc 44 drives the two hoppers 2 to rotate. The controller opens the on / off valve in the feed pipe, and the core material enters the mixing drum 1 from the bottom of the hopper 2 through the feed pipe. Under the stirring action of the stirring blades 72, it is mixed with other materials.

[0038] The top output shaft of the dual-axis motor 41 drives the transmission shaft 61 to rotate, the transmission shaft 61 drives the fixed sleeve 62 to rotate, the fixed sleeve 62 drives the connecting rod 64 to rotate, and the connecting rod 64 drives the flying ball 65 to rotate. Under the action of centrifugal force, the flying ball 65 slides outward along the limiting rod 66, pushing the sliding sleeve 63 to slide upward along the transmission shaft 61. The return spring 68 is stretched, the sliding sleeve 63 drives the transmission plate 69 to slide upward along the limiting shaft 610, the transmission plate 69 drives the piston rod 56 to slide upward, and the piston rod 56 drives the piston plate 55 to slide upward in the piston cylinder 54. A negative pressure is formed in the piston cylinder 54, and outside air enters the piston cylinder 54 through the air inlet pipe 57.

[0039] When the flying ball 65 rotates to the position where the centrifugal force decreases, under the elastic force of the return spring 68, the sliding sleeve 63 slides downward along the transmission shaft 61, driving the transmission plate 69 to slide downward along the limit shaft 610. The transmission plate 69 drives the stopper rod 56 to slide downward, and the stopper rod 56 drives the stopper plate 55 to slide downward in the piston cylinder 54. The air in the piston cylinder 54 is compressed and enters the U-shaped tube 52 through the conveying pipe 58, and then is ejected from the air outlet 53 on the lower surface of the U-shaped tube 52 to blow air into the core material in the hopper 2 to prevent the core material from clogging the hopper 2.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
