Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a screening equipment for welding electrode coating raw materials. Background Technology

[0002] Welding electrodes are widely used consumables in industrial welding. The coating on their outer surface plays a decisive role in the stability of the welding process, the formation of the weld, and its mechanical properties. Electrode coatings are typically made from a mixture of various minerals, ferroalloys, and other powdered raw materials according to a specific formula.

[0003] To ensure uniform coating of the flux and the final welding quality, strict requirements are placed on the particle size of these powdered raw materials. Therefore, before adding the raw materials to the mixing process, they must be screened using sieving equipment to remove particles that do not meet the particle size requirements. This is a crucial preliminary step to ensure the quality of the welding electrodes.

[0004] Existing screening equipment, especially vibrating screens used for processing such fine powders, typically employs a sealed screen cylinder structure with internal screen mesh. However, in actual production processes, different electrode types or production batches may require different formulations of flux coating raw materials, and these raw materials also have different particle size requirements. This necessitates frequent replacement of screens with different mesh sizes.

[0005] Traditional screening equipment often fails to adequately consider the ease of screen replacement in its design. The screens are typically fixed inside the screen cylinder with multiple bolts, or require disassembly of major structural components of the screen cylinder to remove them. This replacement method is not only cumbersome and time-consuming, but also requires specialized tools, resulting in excessive downtime for equipment maintenance and severely impacting the continuity and overall efficiency of the production line. Therefore, this utility model proposes a screening device for welding electrode coating raw materials to address the shortcomings of existing technologies. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a screening device for welding electrode coating raw materials, which aims to improve the problems of cumbersome, time-consuming and labor-intensive screen replacement operations and reduced production efficiency in some existing welding electrode coating raw material screening devices.

[0007] This utility model provides a screening device for welding electrode coating raw materials, including: a screening tube, a filter screen disposed inside the screening tube, a base two and a vibration motor installed inside the base two; and an opening and closing mechanism disposed on the side wall of the screening tube.

[0008] The opening and closing mechanism includes a fixed cover rotatably connected to the opening on the side wall of the screen tube, and a fixing component for locking and unlocking the fixed cover.

[0009] Furthermore, the fixing component is fixed to the screen tube, and a gripper for engaging the fixing cover is rotatably connected to the fixing component; a spring is installed inside the fixing component, which provides a restoring force to the gripper to keep it in the engaging position; the fixing cover is equipped with a handle and a connecting rod. When the handle is pulled to open the fixing cover, the connecting rod will push the gripper to overcome the spring force and rotate to the unlocked position, thereby realizing the convenient opening of the fixing cover.

[0010] Preferably, the fixing component further includes a knob, which is threaded to the support plate and used to lock or release the rotation of the gripper.

[0011] Preferably, the fixed cover is provided with a diamond-shaped buckle for engaging with the opening edge of the screen tube, and the fixed cover is rotatably connected to the fixed block fixed on the screen tube via a connecting sleeve.

[0012] Preferably, the edge of the filter screen is provided with a diamond-shaped buckle 2, which is used to detachably snap and fix the filter screen to the inner wall of the screen tube.

[0013] Preferably, an inclined plate is fixed inside the screening tube and below the filter screen, and a discharge port connected to the lowest point of the inclined plate is provided at the lower part of the screening tube.

[0014] Preferably, the top of the screen tube is detachably fitted with an anti-ejection cover, and the screen tube is elastically connected to the base two by a spring two.

[0015] Preferably, the electrode coating material screening equipment also includes a locking mechanism for opening the screening tube to clean up any residual material inside.

[0016] A further preferred embodiment of the locking mechanism includes a second fixing block and a third fixing block fixed to different parts of the screen tube, a second connecting sleeve and a third connecting sleeve rotatably connected to the second fixing block and the third fixing block respectively, and a second knob for operating the second connecting sleeve.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting an opening and closing mechanism, which includes a fixed cover rotatably connected to the screen tube and a fixing component for locking and unlocking the fixed cover, solves the problem that existing screening equipment requires disassembling multiple bolts or major components when replacing the screen, which is cumbersome, time-consuming and labor-intensive. It achieves the technical effect of being able to quickly and conveniently open the side wall of the screen tube and replace the filter screen, significantly shortening the equipment maintenance time and improving production efficiency.

[0018] This utility model, by setting a locking mechanism, can lock or unlock the main body of the screening tube through the cooperation of the connecting sleeve and the fixing block. This solves the problem that the existing screening equipment has an integrated structure, making it difficult to thoroughly clean the internal residual materials and easily causing cross-contamination of raw materials from different batches. It achieves the technical effect of facilitating thorough cleaning of the inside of the equipment, effectively avoiding raw material contamination, and ensuring the accuracy of the welding rod coating formula.

[0019] This utility model integrates the opening and closing mechanism with the locking mechanism into the screening equipment, and designs a linkage mechanical structure including a handle, gripper, spring and connecting rod. It solves the problems of existing equipment having a single structure, poor functional expandability, and inability to simultaneously meet the needs of quick screen changing and thorough cleaning. It achieves the technical effect of ingenious equipment structure, humanized operation, improved equipment maintainability and applicability, and is particularly suitable for production occasions that require frequent changes of material types.

[0022] 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.

[0023] Example: Reference Figures 1 to 4 This utility model provides a screening device for welding electrode coating raw materials, which aims to solve the problems of complex, time-consuming and labor-intensive operation of replacing screens and cleaning internal materials in the existing welding electrode coating raw material screening device.

[0024] like Figure 1 As shown, the equipment includes a screening pipe 2 as the main body, a base 11 elastically connected to the bottom of the screening pipe 2, and a vibration motor 10 installed inside the base 11. The screening pipe 2 is elastically connected to the base 11 via a spring 9. The vibration motor 10 drives the screening pipe 2 to vibrate. A cover 1 is detachably installed on the top of the screening pipe 2. A filter screen 5 for screening materials is detachably installed inside the screening pipe 2. An inclined plate 7 is fixed inside the screening pipe 2 and below the filter screen 5. A discharge port 8 connected to the lowest point of the inclined plate 7 is provided at the bottom of the screening pipe 2. The welding rod coating raw material screening equipment is equipped with an opening and closing mechanism 3. (Refer to...) Figure 1 , Figure 3 and Figure 4 The opening and closing mechanism 3 includes a fixed cover 31, which is rotatably connected to the side wall opening of the screen tube 2. A handle 32 is fixedly connected to the fixed cover 31. The opening and closing mechanism 3 also includes a fixing component 34 for locking and unlocking the fixed cover 31.

[0025] The fixing assembly 34 includes a base 341 fixed to the outer wall of the screen tube 2, a support plate 342 fixed to the base 341, a rotating shaft 343 rotatably connected to the support plate 342, and a gripper 346 fixedly connected to the rotating shaft 343. The gripper 346 is used to engage the fixing cover 31, thereby locking the fixing cover 31. The fixing assembly 34 also includes a spring 344 and a connecting plate 345. One end of the spring 344 abuts against the base 341, and the other end abuts against the connecting plate 345. The connecting plate 345 connects the spring 344 and the gripper 346. The elastic force is applied to the gripper 346 through the connecting plate 345 to drive the gripper 346 to remain in the latched position. A connecting rod 35 is fixedly connected to the fixed cover 31. When the operator pulls the handle 32 to open the fixed cover 31, the end of the connecting rod 35 will push the gripper 346, causing the gripper 346 to overcome the elastic force of the spring 344 and rotate to the unlocked position, thereby releasing the fixed cover 31. The fixing assembly 34 also includes a knob 347, which is threaded to the support plate 342 and is used to abut or disengage from the gripper 346 after rotation, so as to lock or release the rotation of the gripper 346.

[0026] The opening and closing mechanism 3 also includes a fixing block 36 fixed to the screen tube 2. The fixing cover 31 is rotatably connected to the fixing block 36 through the connecting sleeve 37. At the same time, the fixing cover 31 is provided with a diamond-shaped buckle 33 inside. The diamond-shaped buckle 33 is used to engage with the edge of the side wall opening of the screen tube 2 to enhance the reliability of the fixation.

[0027] Reference Figure 1 The locking mechanism 4 includes a second fixing block 41 and a third fixing block 44, which are respectively fixed on both sides of the part of the screen tube 2 that needs to be separated. The locking mechanism 4 also includes a second connecting sleeve 42 and a third connecting sleeve 45. The second connecting sleeve 42 is rotatably connected to the second fixing block 41, and the third connecting sleeve 45 is rotatably connected to the third fixing block 44. In the locked state, the second connecting sleeve 42 and the third connecting sleeve 45 are simultaneously fastened to the two separable parts of the screen tube 2 to fasten the screen tube 2 into a whole.

[0028] The locking mechanism 4 is also equipped with a knob 43, which is used to lock or release the rotation of the connecting sleeve 42. When it is necessary to clean the inside of the screen tube 2, the knob 43 is operated to release the connecting sleeve 42. Then the connecting sleeve 42 and the connecting sleeve 45 can be rotated in sequence to release the locking of the screen tube 2 and allow it to be opened.

[0029] Reference Figure 2The filter screen 5 has a diamond-shaped buckle 6 on its edge, and the inner wall of the screening tube 2 has a groove that matches the diamond-shaped buckle 6. In the assembled state, the filter screen 5 is fixed to the inner wall of the screening tube 2 by its diamond-shaped buckle 6. This fixing method ensures that the filter screen 5 can be easily pulled out for replacement or cleaning after the fixing cover 31 is opened by the opening and closing mechanism 3.

[0030] Reference Figure 3 The knob 347 is threaded to the support plate 342. By rotating the knob 347, the end of its rod can extend or retract, thereby locking or releasing the gripper 346.

[0031] Reference Figure 4 The opening and closing mechanism 3 also includes a fixing block 36 fixed to the outer wall of the screen tube 2. The fixing cover 31 is rotatably connected to the fixing block 36 through the connecting sleeve 37. At the same time, a diamond-shaped buckle 33 is provided on the inner side wall of the fixing cover 31. The diamond-shaped buckle 33 is used to engage with the edge of the side wall opening of the screen tube 2 to enhance the sealing and stability in the closed state.

[0032] Reference Figure 1 An inclined plate 7 is fixedly welded inside the screen tube 2 and below the filter screen 5. The inclined plate 7 has a certain inclination angle, and its lowest point is connected to the discharge port 8 opened at the bottom of the screen tube 2. An anti-discharge cover 1 is detachably installed at the top opening of the screen tube 2 by means of threads or snaps. At the same time, in order to enhance the vibration effect of the vibration motor 10 on the screen tube 2, multiple springs 9 are provided between the screen tube 2 and the base 11 as elastic connecting parts.

[0033] The implementation principle of this application embodiment is as follows: When performing the screening operation, first remove the anti-outflow cover 1, pour the raw material from the top of the screening tube 2, and the raw material falls on the filter screen 5. Then, install the anti-outflow cover 1, start the vibration motor 10 inside the base 2 11, and the high-frequency vibration generated by the vibration motor 10 is transmitted and amplified to the entire screening tube 2 through the spring 2 9, so that the screening tube 2, together with the internal filter screen 5 and the raw material, will vibrate continuously. Raw material particles with a size smaller than the mesh of the filter screen 5 pass through the screen under the action of vibration, fall onto the inclined plate 7 below, and automatically slide along the inclined surface of the inclined plate 7 to the discharge port 8 for discharge. Larger raw materials are left on the filter screen 5.

[0034] When the filter screen 5 needs to be replaced, first rotate the knob 347 in the fixing assembly 34 to release the lock on the gripper 346. Then pull the handle 32 of the opening and closing mechanism 3 outward. The handle 32 drives the fixing cover 31 to move outward. The connecting rod 35 on the fixing cover 31 will push the gripper 346, forcing the gripper 346 to rotate around the rotating shaft 343 and overcome the elastic force of the spring 344, thereby disengaging from the fixing cover 31. At this time, the diamond-shaped buckle 33 inside the fixing cover 31 also disengages from the screen tube 2. The operator can continue to rotate the fixing cover 31 around the connection point between the connecting sleeve 37 and the fixing block 36 to open it, exposing the side wall opening of the screen tube 2. Then, directly pull out the filter screen 5 with the diamond-shaped buckle 6 to complete the replacement.

[0035] When screening is complete and the inside of the equipment needs to be thoroughly cleaned, first rotate the knob 43 in the locking mechanism 4 to unlock the connecting sleeve 42. Then rotate it upwards to open the connecting sleeve 42 and the connecting sleeve 45, releasing their fastening effect on the screening tube 2. At this time, the screening tube 2 can be separated and opened, making it convenient to clean the residual raw materials inside.
