Description

Specification 1 A Vertical Double-Layer Silo for Welding Machines Technical Field This application relates to the technical field of welding machine silos, specifically a vertical double-layer silo for welding machines. Background Art Welding machines are currently existing automated equipment, used in conjunction with production lines for welding processing. Welding machine pallets, through automatic loading and unloading components, work with the silo to complete the processing and storage of raw materials. Referring to the inventor's authorized patent, Publication No. CN217262773U, a utility model patent describes a vertical double-layer silo for welding machines, including a support frame. A lifter for driving changes in the height of the support frame is installed on one side of the support frame, and a driver for driving the lifter's lifting and lowering is connected to the top of the lifter. This vertical double-layer hopper for welding machines allows for automatic loading and unloading when one hopper needs replacement. The driver activates a lifting mechanism, which moves the support frame horizontally along the Z-axis, aligning the other hopper with the guide frame. The pneumatic clamps on the corresponding hopper surface then close, facilitating hopper replacement. This method ensures continuous automated production without downtime and provides ample reaction time for operators, significantly improving the stability of the production line. The aforementioned patent addresses the issue of reduced processing efficiency when a single hopper is full by introducing a double-layer hopper. However, relying on manual unloading after hopper division still results in low efficiency. This invention proposes a vertical double-layer hopper for welding machines to solve these problems. The utility model addresses the shortcomings of existing technologies by providing a vertical double-layer hopper for welding machines with advantages such as automatic unloading and no need for manual unloading. To achieve the above objectives, this application provides the following technical solution: a vertical double-layer hopper for a welding machine, comprising a support frame, a feeding mechanism on one side of the support frame, an extension frame fixedly mounted on the support frame, a hopper slidably mounted inside the extension frame, a top plate fixedly mounted on the top of the extension frame, and a platform fixedly mounted on the top of the hopper, the platform extending to the front and rear sides of the hopper; the unloading structure includes a rotating sleeve rotatably mounted on the side of the extension frame away from the support frame, a torsion spring fixedly mounted between the rotating sleeve and the surface of the extension frame, a support block fixedly mounted on the side of the rotating sleeve facing the middle of the extension frame, an abutment block fixedly mounted on the side of the rotating sleeve away from the middle of the extension frame, a stop bar fixedly mounted on the side of the extension frame, the abutment block abutting against the stop bar, and a lifting cylinder fixedly mounted on the bottom of the support frame. Furthermore, a pneumatic clamp is also fixedly mounted on the support frame. Furthermore, a guide plate is fixedly installed on the side of the extension frame. Furthermore, both the support block and the abutment block are trapezoidal, and the inclined surface of the support block faces downwards.Furthermore, a servo motor is fixedly mounted on the top of the top plate via a bracket, and a gear shaft is fixedly mounted on the output end of the servo motor. A rack is fixedly mounted on the top of the hopper, and the gear shaft teeth mesh with the rack. Furthermore, a groove is formed on the top of the top plate, and the gear shaft passes through the groove. Furthermore, a double-layer transmission platform is fixedly mounted on one side of the support frame. Compared with the prior art, the technical solution of this application has the following beneficial effects: This welding machine has a vertical double-layer hopper. By setting the support frame to fix the position, and simultaneously setting an extension frame to guide the hopper's vertical movement, the double-layer transmission platform, in conjunction with a lifting cylinder, enables the hopper to automatically switch without stopping production. By setting the top plate, gear shaft, and rack, the hopper can be pulled away from the extension frame and pushed by the double-layer transmission platform, thus automating both the unloading and loading of the hopper and improving the overall efficiency of the production line.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Please refer to Figures 1-3. In this embodiment, a vertical double-layer hopper for a welding machine includes a support frame 1. A feeding mechanism 2 is provided on one side of the support frame 1. Specifically, the feeding mechanism 2 is the structure disclosed in publication number CN217262773U. In this embodiment, an extension frame 3 is fixedly installed on the support frame 1, and a hopper 4 is slidably installed inside the extension frame 3. A pneumatic clamp 5 is also fixedly installed on the support frame 1 to fix the hopper 4. A top plate 6 is fixedly installed on the top of the extension frame 3, and a discharge structure is also provided on the extension frame 3.It should be noted that a platform 7 is fixedly installed on the top of the hopper 4, extending to the front and rear sides of the hopper 4, so that the front and rear sides of the hopper 4 extend with edges to facilitate the guidance of the hopper 4. The unloading structure includes a rotating sleeve 9 rotatably installed on the side of the extension frame 3 away from the support frame 1, and a torsion spring 8 fixedly installed between the rotating sleeve 9 and the surface of the extension frame 3. The torsion spring 8 pulls the rotating sleeve 9 to rotate and reset. In this embodiment, a support block 10 is fixedly installed on the side of the rotating sleeve 9 facing the middle of the extension frame 3, and an abutment block 11 is fixedly installed on the side of the rotating sleeve 9 away from the middle of the extension frame 3. A stop bar 12 is also fixedly installed on the side of the extension frame 3, and the abutment block 11 abuts against the stop bar 12. By the abutment block 11 abutting against the stop bar 12, the unidirectional rotation of the rotating sleeve 9 can be restricted. A guide plate 13 is fixedly installed on the side of the extension frame 3. The guide plate 13 is used to restrict the hopper 4, thereby stabilizing the movement of the hopper 4. HK 20109780 B Specification 4 In this embodiment, both the support block 10 and the abutment block 11 are trapezoidal, and the inclined surface of the support block 10 faces downward, so that the platform 7, which moves from bottom to top, can abut against the inclined surface of the support block 10 and squeeze the support block 10 to rotate. In order to realize the automatic replacement of the hopper 4, a lifting cylinder 17 is fixedly installed at the bottom of the support frame 1 in this embodiment. When the pneumatic clamp 5 is released, the lifting cylinder 17 can simultaneously push the two stacked hoppers 4 to move upward along the extension frame 3, so that the hopper 4 located at the bottom can replace the hopper 4 in the middle. In this embodiment, a servo motor 14 is fixedly installed on the top of the top plate 6 by a bracket. A gear shaft 15 is fixedly installed on the output end of the servo motor 14. A rack 19 is fixedly installed on the top of the hopper 4. The gear shaft 15 meshes with the rack 19. The rotation of the gear shaft 15 can drive the hopper 4 to slide. It should be noted that a groove 16 is provided on the top of the top plate 6. The groove 16 is used to provide extension space for the gear shaft 15, so that the gear shaft 15 can mesh with the rack 19. In this embodiment, a double-layer transmission table 18 is fixedly installed on one side of the support frame 1. The double-layer transmission table 18 can be set as a feeding mechanism 2. Through the transmission table 18, the material bin 4 can be fed in and the material bin 4 below the top plate 6 can be fed out, realizing automatic feeding and unloading.The working principle of the above embodiment is as follows: During use, when the middle hopper 4 needs to be replaced, the lifting cylinder 17 is driven to push the lowermost hopper 4 upward along the extension frame 3. At this time, the pneumatic clamp 5 on the surface of the hopper 4 is closed. The lowermost hopper 4 is then lifted to replace the middle hopper 4 and continue to complete the feeding. During the upward movement of the hopper 4, the outer edge 7 of the hopper 4 presses against the support block 10. After passing the support block 10, the support block 10 supports the edge 7, thereby lifting the hopper 4. At the same time, the pneumatic clamp 5 is opened to lock the middle hopper 4 to participate in the production line. The hopper 4 lifted to below the top plate 6 is lifted by a set of support blocks 10 above. At this time, the servo motor 14 is driven, which drives the gear shaft 15 on the output end to rotate. The gear shaft 15 meshes with the rack 19 through its teeth, thereby driving the uppermost hopper 4, so that the hopper 4 slides on the support block 10 through the edge 7 and exits the extension frame 3. The material falls onto the double-layer conveyor 18, completing automatic unloading. At this time, the lower layer of the double-layer conveyor 18 transports the empty hopper to the support frame 1 for later use.
