Description

Technical Field

[0001] The utility model relates to the technical field of welding rod pressure coating, in particular to a pressure coating device for producing acid welding rods. Background Art

[0002] Welding rod coating is a crucial step in welding rod manufacturing. It involves evenly applying flux to the core to form the outer coating. Prior to coating, the flux is mixed according to a specific formula and ratio and sieved to ensure uniform particle size. The core, the main component of the welding rod, is typically made of mild steel or another alloy, with a diameter and length determined by the rod specification. The flux and core are fed into a coating machine, which typically consists of one or more rollers or platens that rotate or move to apply the flux evenly to the core. During the coating process, the flux is subjected to pressure and friction, which adheres tightly to the core, forming a uniform coating. In short, welding rod coating is a crucial step in the manufacturing process and plays a vital role in ensuring the quality and performance of the welding rod.

[0003] For example, the Chinese patent "A coating machine for producing coated welding rods" with announcement number CN203508328U includes a wire feeding mechanism, a wire guide tube, a hydraulic cylinder, a powder coating cylinder, a retaining frame, a pointed head, a cylinder cover, and a powder coating mold. One end of the wire guide tube is connected to the wire outlet of the wire feeding mechanism, passing through the center of the hydraulic cylinder, the center of the powder coating cylinder to the center of the retaining frame. The center lines of the powder coating mold, the pointed head, the retaining frame, the powder coating cylinder, the cylinder cover, the center line of the hydraulic cylinder, and the center line of the wire feeding outlet of the wire feeding mechanism are all on the same straight line. The powder coating cylinder and the cylinder cover form a regular cavity composed of a cylinder and a corresponding right cone. The piston rod of the hydraulic cylinder consists of a rod body and a head. The rod body and the head have the same center line as the hydraulic cylinder.

[0004] Although the above-mentioned existing technology can realize the pressure coating of welding rods, in actual use, on the one hand, the loading of welding rods is not convenient enough. When loading welding rods, the operator needs to push a welding rod into the pressure coating device, resulting in the need for personnel assistance in the pressure coating of the welding rods, thereby increasing the workload of the operator. On the other hand, the sticky pressure coating raw materials are prone to agglomeration. After the pressure coating raw materials are put into the pressure coating device, the raw materials with a certain viscosity will form agglomerates, causing the agglomerated raw materials to adhere to the outside of the welding rod, resulting in the welding rod pressure coating being not uniform. Therefore, it does not meet the existing needs. In this regard, we propose a pressure coating device for the production of acid welding rods. Utility Model Content

[0005] The purpose of the present invention is to provide a pressure coating device for producing acid welding rods, so as to solve the problems in the above background technology that welding rod feeding is not convenient enough and the sticky pressure coating raw materials are prone to agglomeration.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a pressure coating device for acid welding rod production, comprising a frame, wherein two frames are provided, a workbench is fixedly provided on the upper end of the frame, and a first mounting frame is fixedly provided at the front and rear ends of the upper end of the workbench; and further comprising:

[0007] A second mounting frame is provided on both sides of the upper end of the first mounting frame, and a rotating rod is provided at the front and rear ends between the transverse plates of the second mounting frame, and the rotating rod is rotatably connected to the transverse plates of the second mounting frame, and a limiting roller is fixedly provided on the outside of the rotating rod, and a gap between the limiting rollers on both sides can pass through a welding rod;

[0008] An upper hopper is arranged at the upper end of the second mounting frame, and the upper hopper is fixedly connected to the second mounting frame.

[0009] Preferably, a first motor is fixedly mounted on the front and rear ends of one side of the outer portion of the second mounting frame, and the output shaft of the first motor extends to the other side of the second mounting frame and is fixedly connected to the rotating rod.

[0010] Preferably, a feed pipe is provided at the lower end of the limiting roller between the first mounting brackets, and the feed pipe is fixedly connected to the second mounting bracket, and a pressure coating pipe is fixedly provided at the lower end of the feed pipe, and the feed pipe is connected to the pressure coating pipe.

[0011] Preferably, the front and rear ends of the pressure-coated tube are fixedly provided with a feed pipe, and the feed pipe is connected to the pressure-coated tube, a mounting rod is provided inside the feed pipe, and the mounting rod is rotatably connected to the inner wall of the feed pipe, a spiral blade is fixedly provided on the outside of the mounting rod, and a feeding pipe is fixedly provided on the upper end of the outside of the feed pipe, and the feeding pipe is connected to the feed pipe.

[0012] Preferably, a second motor is fixedly provided on the outside of the feeding tube, and the output shaft of the second motor extends into the inside of the feeding tube and is fixedly connected to the mounting rod.

[0013] Preferably, a hydraulic telescopic device is provided on one side of the outside of the extruded tube, and the telescopic end of the hydraulic telescopic device extends to the inside of the extruded tube, and an extrusion plate is fixedly provided on one side of the telescopic end of the hydraulic telescopic device inside the extruded tube.

[0014] Preferably, a sealing tube is provided on the other side of the outside of the extruded tube, a heating tube is provided on the other side of the sealing tube, a heating wire is provided inside the heating tube, and the heating wire is distributed in a spiral shape.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model can automatically load the welding rod through the limiting roller and the first motor. When the welding rod is press-coated, the press-coating raw material has been filled. At this time, the welding rods are placed in the loading hopper, and the first motors on both sides are started synchronously, so that the output shafts of the first motors drive the rotating rods to rotate, and at the same time, the power supply direction of the first motor is changed, so that the rotating rod drives the limiting roller fixedly connected thereto to rotate back and forth. During the reciprocating rotation of the limiting roller, the friction force causes the welding rods concentrated on the upper end of the limiting roller to pass through the gap between the limiting rollers on both sides in turn and fall into the feeding pipe below, so that the welding rods can be automatically loaded while avoiding accumulation of welding rods, thereby making the press-coating of the welding rods more uniform.

[0017] 2. The utility model can push the raw materials into the pressure-coating tube through the spiral blades and the feeding tube. When the pressure-coating raw materials are filled, the raw materials are mixed and put into the feeding tube through the feeding tube. At this time, the second motor is turned on to make the output shaft of the second motor drive the mounting rod to rotate. When the mounting rod rotates, the spiral blade fixedly connected to it also rotates together. The rotating spiral blade pushes the pressure-coating raw materials to move into the pressure-coating tube. At the same time, the spiral blade can reduce the agglomeration of the pressure-coating raw materials during the rotation process. When the pressure-coating raw materials are transported to the pressure-coating tube, the pressure-coating raw materials are adhered to the outside of the welding rod by extrusion, thereby avoiding the generation of agglomerations between the accumulated pressure-coating raw materials. At the same time, the welding rod is pressure-coated by the extrusion force.

[0018] 3. The utility model can dry the moist pressed-coated raw materials through the heating tube and the heating wire. When the welding rod is pressed and coated, the pressed-coated welding rod enters the heating tube through the sealing tube. At this time, the heating wire is energized. After the current passes through the heating wire with a certain resistance, the heating wire generates heat, and the heat is transferred to the welding rod through the tube wall of the heating tube, so that the temperature of the welding rod rises while drying the moist and sticky pressed-coated raw materials, thereby reducing cracks between the raw materials and improving the production quality of the welding rod.
