Description

Technical Field

[0001] The utility model relates to the technical field of continuous mesh belt furnace heat treatment production lines, and particularly relates to a scraping device for a continuous mesh belt furnace heat treatment production line. Background Art

[0002] All along, for the well-known continuous mesh belt furnace heat treatment production line, the heat-treated parts produced are quenched at high temperature, and the quenching medium is water-based, oil or salt. After quenching, the continuous mesh belt lifts the quenched parts from the medium to the tempering mesh belt furnace or the basket. Due to the presence of the medium, especially in salt bath isothermal quenching, the salt wraps the parts. When the mesh belt holds the parts and separates from the salt bath, the parts and the mesh belt cool down, and the salt wrapping the parts changes from liquid to solid, resulting in the parts being easily adhered to the mesh belt, thus unable to be unloaded, and causing the parts to re-enter the salt bath. Previously, blowing air, spraying water and wire scraping were used, but the scraping effect was not ideal and it was impossible to achieve 100% scraping.

[0003] As described above, the continuous mesh belt furnace heat treatment production line operates continuously for 24 hours. Due to unclean scraping, the parts re-enter the furnace. After a long time, they all accumulate at the bottom of the furnace and need to be cleaned regularly. The direct economic loss caused by regular cleaning and part loss per line is 180,000 yuan per year. And the indirect loss caused by the confusion of re-entering parts and normal parts is even greater, which directly affects the life and reliability of the parts. Summary of the Utility Model

[0027] Combined with the attached Figures 1 - 3 drawings, a scraping device for a continuous mesh belt furnace heat treatment production line in this embodiment includes a support rod 1. The support rod 1 is arranged along the direction parallel to the width of the mesh belt. The support rod 1 is arranged at one end of the mesh belt. A plurality of scraping springs 2 are arranged at intervals along the axial direction of the support rod 1. One end of each scraping spring 2 abuts against the mesh belt. The plurality of scraping springs 2 are arranged along the same radial direction of the support rod 1. An actuator for pushing the support rod 1 to reciprocate is further included.

[0028] The scraping device of this continuous mesh belt furnace heat treatment production line drives the scraping spring 2 to reciprocate on the mesh belt through the support rod 1. Since the scraping spring 2 is in direct contact with the mesh belt, the parts on the mesh belt can be directly scraped off. When there are protrusions on the mesh belt, the scraping spring 2 can also bend to avoid interference. Compared with the transmission mechanisms such as blowing, wire scraping, and water spraying, its scraping performance is more stable and reliable, and it is suitable for various harsh environments.

[0029] As an alternative solution of the present utility model, a rotating shaft sleeve 3 is sleeved on the support rod 1. The rotating shaft sleeve 3 can only rotate relative to the support rod 1.

One end of the extension rod 4 is connected to the lower end of the rotating shaft sleeve 3, and the other end of the extension rod 4 is close to the mesh belt and connected to the scraping spring 2 to prevent the scraping spring 2 from being too long and affecting its scraping effect.

[0031] As an alternative solution of the present utility model, a weight structure is provided on the rotating shaft sleeve 3. The scraping spring 2 is arranged between the weight structure and the mesh belt. The weight structure applies gravity to the rotating shaft sleeve 3 to cause the rotating shaft sleeve 3 to have a tendency to rotate, thereby improving the fitting strength between the scraping spring 2 and the mesh belt, effectively improving the scraping success rate, and reducing the production cost.

[0032] As an alternative solution of the present utility model, the weight structure includes a weight frame 5 and a weight block 6. One end of the weight frame 5 is connected to the rotating shaft sleeve 3, and the other end is connected to the weight block 6. A hook 7 is provided at the end of the weight frame 5 connected to the rotating shaft sleeve 3. The weight frame 5 is connected to the rotating shaft sleeve 3 through the hook 7. An anti-slip pad is provided inside the hook 7. The hook 7 and the rotating shaft sleeve 3 can be connected by fasteners such as bolts. The weight frame 5 and the weight block 6 are detachably connected, and a suitable weight is selected according to the size of the scraping force.

[0033] As an alternative solution of the present utility model, the actuating mechanism includes a motor fixing frame 8 fixed on the production line; a motor 9 connected to the motor fixing frame 8; a crank connecting rod 10 drivingly connected to the output shaft of the motor 9 and the support rod 1. One end of the support rod 1 connected to the crank connecting rod 10 is connected with a rocker through a coupling. The rocker is rotatably connected to the end of the crank connecting rod 10. The actuating mechanism further includes a pulley group 11 for supporting the support rod 1. The crank connecting rod 10 drives the support rod 1 to move synchronously along its axial and radial directions to further improve the scraping effect of the scraping spring 2, as shown in the appendix Figure 1As shown, when the support rod 1 reciprocates, it will move left and right as well as up and down.

[0034] As an alternative embodiment of the present utility model, the pulley block 11 includes two pulleys arranged at intervals along the axial direction of the support rod 1. The pulleys are installed on the production line. When the support rod 1 swings, the positions of the pulleys do not change and they only rotate when contacting the support rod 1.

[0035] The above has schematically described the present utility model and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
