[0002] A mesh belt furnace is a sintering furnace that continuously transports objects through a mesh conveyor belt and performs multi-stage processing on the materials during the transportation process. It is mainly used for sintering powder metallurgy products and reducing metal powders, as well as pre-firing, firing or heat treatment processes of electronic products in a protective atmosphere or air.

[0003] The inlet end of the existing mesh belt furnace is provided with a feeding mechanism, which generally needs to be flush with or slightly higher than the inlet end of the mesh belt furnace. Therefore, when loading materials, workers need to lift the workpiece in the material cart and pour it into the feeding mechanism, which is labor-intensive and also poses a risk.

[0027] Please refer to Figures 1 to 2 , a vertical turning mechanism of a mesh belt furnace shown in an embodiment of the present application includes a bracket 1, a vibrating plate 2, a charging hopper 3 and a turning assembly 4. The bracket 1 is fixedly arranged near the feeding end of the mesh belt furnace and is fixedly placed on the ground.

[0028] The vibration plate 2 is arranged on the bracket 1 and the outlet end is connected to the feed end of the mesh belt furnace. The vibration plate 2 mainly relies on mechanical vibration to realize automatic transportation and flattening of materials. It is an existing technology and will not be described in detail here.

[0029] The loading hopper 3 is arranged on the bracket 1 and is located directly above the vibrating disk 2; the loading hopper 3 is funnel-shaped, and its bottom extends into the vibrating disk 2, and the bottom end of the loading hopper 3 is provided with a paving plate 31 extending obliquely along the outlet end of the vibrating disk 2, and the paving plate 31 is suspended directly above the outlet end of the vibrating disk 2. The cross-sectional area of ​​the loading hopper 3 tends to abut from top to bottom, so that the top inlet is larger than the bottom outlet, which is convenient for receiving the workpieces in the material cart 5. At the same time, the number of workpieces falling from the bottom outlet is controlled to facilitate the vibrating disk 2 to flatten the workpieces. At the same time, the workpieces can be flattened for a second time by the paving plate 31 suspended at the outlet end of the vibrating disk 2 to ensure that the workpieces are evenly distributed.

[0030] The tipping assembly 4 includes a track 42 arranged on the bracket 1, a tipping hopper 41 slidably arranged on the track 42, and a power member 43 driving the tipping hopper 41 to move on the track 42. The track 42 extends from the bottom of the bracket 1 to above the loading hopper 3, and the top surface of the tipping hopper 41 is provided with a top opening.

[0031] Among them, driven by the power part 43, the tipping hopper 41 has a first position a located at the bottom of the bracket 1 and a second position b located above the charging hopper 3. The tipping hopper 41 is in the first position a, and the top opening faces directly upwards. The tipping hopper 41 is in the second position b, and the top opening is inclined toward the top of the charging hopper 3.

[0032] In one embodiment, the track 42 includes a vertically arranged straight segment and an arc segment connected to the top of the straight segment, and the arc segment extends above the loading hopper 3. Four sets of tracks 42 are provided, and the four sets of tracks 42 are symmetrically slidably connected to the two sides of the tipping hopper 41. Each set of tracks 42 includes an inner track 421 and an outer track 422. The tipping trolley 5 is provided with a connecting shaft, and the connecting shaft is provided with a bearing 413. The bearing 413 is arranged between the inner track 421 and the outer track 422. When the power unit 43 drives the tipping trolley to move, the track 42 guides the tipping trolley to lift and flip it to a certain angle to pour the workpiece into the loading hopper 3.

[0033] In one embodiment, the power member 43 includes a drive motor 431 and a transmission structure connected between the drive motor 431 and the tipping hopper 41. The transmission structure includes a driving gear 432 disposed on the output shaft of the drive motor 431, a driven gear 433 disposed on the tipping hopper 41, and a chain 434 connected between the driving gear 432 and the driven gear 433. The chain 434 extends along the conveying path of the track 42. The motor drives the chain 434 to move the tipping hopper 41, and the tipping hopper 41 is turned and discharged under the guidance of the track 42.

[0034] In one embodiment, a side opening is provided on the side of the tipping hopper 41 for the trolley 5 to enter or exit the tipping hopper 41. When the tipping hopper 41 is in the first position a, the bottom of the side opening is slightly above the ground, so the trolley 5 can be directly pushed into the tipping hopper 41, effectively reducing the workload of placing the trolley 5 into the tipping hopper 41.

[0035] In one embodiment, the tipping hopper 41 is further provided with a pouring funnel 412 connected to the top opening. The cross-sectional area of ​​the pouring funnel 412 decreases gradually from bottom to top. By providing the pouring funnel 412 at the top opening, the workpieces in the trolley 5 can be collected and poured into the loading hopper 3 during unloading, preventing the workpieces from being scattered outside the loading hopper 3.

[0036] In one embodiment, a limiting structure is provided within the tipping hopper 41. The limiting structure includes limiting plates 411 disposed on either side of the tipping hopper 41 and a limiting block (not shown) disposed near the top opening. The limiting plates 411 are used to limit the position of the trolley 5 within the tipping hopper 41 so that the discharge port of the trolley 5 is aligned with the top opening, while the limiting block is used to limit the movement of the trolley 5 toward the top opening. This arrangement facilitates locking the position of the trolley 5, preventing it from falling out of the tipping hopper 41 and facilitating material discharge.

[0037] In one embodiment, the vertical turning mechanism further comprises a ladder 6 provided on the side of the bracket 1, the top of the ladder 6 being flush with the bottom of the vibrating plate 2. The ladder 6 allows workers to check the number of workpieces in the loading hopper 3 for timely loading.

[0038] The present application sets a tipping hopper near the bottom of the bracket so that the material cart can be placed directly in the tipping hopper, and uses a power piece to drive the tipping hopper to move the material cart from a first position on the ground to a second position above the charging hopper. During this process, the tipping hopper flips a certain angle to turn its top opening toward the charging hopper, thereby directly pouring the workpiece in the material cart into the charging hopper, avoiding manual pouring and effectively reducing work intensity. At the same time, the vibrating plate set in the charging hopper is used to vibrate and flatten the workpiece and transport it to the inlet end of the mesh belt furnace, so that the workpiece is heated evenly during the heat treatment process, thereby improving the heat treatment effect.

[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
