Description

Technical Field

[0001] The invention relates to the technical field of conveying mechanisms, in particular to a high-temperature turning conveying mechanism for a furnace. Background Art

[0002] Furnace-grade tilting conveyor mechanisms are critical buffer devices between the heating furnace and the quenching chamber. Their reliability and stability are crucial to the continuous operation and efficiency of the entire heat treatment line. Current designs rely on a welded frame and indirect transmission system, with textured or raised surfaces on the conveyor rollers to enhance slip resistance. However, while this solution is effective at room temperature, it significantly degrades stability and reduces conveying efficiency under high-temperature conditions (such as when transferring workpieces from the furnace to the quenching tank). For example, conventional conveyor rollers typically utilize knurled or welded mace-like protrusions to prevent slippage. However, due to manufacturing limitations, the knurling has a limited radial depth, rendering it essentially ineffective in environments with heavy oil smoke and oil deposits. Welded structures are not suitable for high-frequency hardening heat treatment and are prone to thermal detachment. The difference between the weld material and the roller's base material can also lead to thermal detachment. Furthermore, welded structures suffer from inconsistent weld point size and appearance, which can easily cause workpiece deviation. To address this issue, we propose a high-temperature tilting conveyor mechanism for furnaces. Summary of the Invention

[0003] The object of the present invention is to provide a high-temperature turning and conveying mechanism for a furnace to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-temperature flip conveying mechanism for a furnace, comprising a fixed conveyor frame and a flip conveyor frame arranged between a heating chamber and a quenching chamber, wherein both conveyor frames are composed of two sets of support frames arranged opposite to each other and rollers rotatably connected between the opposite support frames through bearings, the two sets of support frames of the flip conveyor frame are located inside the two sets of support frames of the fixed conveyor frame, the flip conveyor frame and the fixed conveyor frame have an overlap, and the two share the same roller in the overlapping area, the roller in the overlapping area is a main shaft, one end of the main shaft extends to the outside of the outer support frame, each adjacent roller member is connected by a gear transmission to maintain synchronization and rotate simultaneously, a flip shaft rotatably connected to the support frame on the fixed conveyor frame is coaxially provided at the other end opposite to the extended end of the main shaft, one end of the flip shaft is fixed to the support frame of the flip conveyor frame, and the flip shaft rotates to make the flip conveyor frame horizontal or vertical. When flipped to a horizontal state, the flip conveyor frame docks to the heating chamber, the axes of each roller are horizontal and at the same height and synchronously transport the workpiece from the heating chamber to the quenching chamber, and the surface of each roller is provided with a machined integrally formed protrusion.

[0005] Preferably, the bearing between the roller and the support frame adopts an open structure with a large gap, and the oil smoke enters the bearing for lubrication.

[0006] Preferably, the protrusions on the surface of the roller are arranged in an annular array around the circumference of the surface of the roller and are staggered in the axial direction of the roller.

[0007] Preferably, the protrusion on the roller surface is conical, and the cross-section decreases radially outward from the roller surface.

[0008] Preferably, the protrusions on the roller surface are a symmetrical inverted four-sided structure.

[0009] Preferably, a mounting shaft is rotatably connected between the two sets of opposing support frames, a fixing rod is fixed radially outward on the mounting shaft, a wiping plate is hinged to the outer end of the fixing rod, and the rotation direction of the mounting shaft is opposite to and synchronized with the rotation direction of the adjacent roller shaft. When the roller shaft and the mounting shaft rotate relative to each other, the wiping plate contacts the side surface of the protrusion and moves to the apex of the protrusion as the wiping plate rotates to wipe it.

[0010] Preferably, the wiper plate is composed of a first plate body and a second plate body, the first plate body is connected to the outer end of the fixed rod through a torsion spring range, the second plate body is connected to the first plate body through a torsion spring range, and the initial deformation force of the torsion spring on the first plate body is greater than the initial deformation force of the torsion spring on the second plate body, and the length of the second plate body exceeds that of the first plate body, and the two are in contact with each other in the initial state. During rotation, the protrusion first contacts the second plate body and causes the second plate body to rotate relative to the first plate body. Under the pull of the first plate body, the second plate body rotates and fits against the protruding surface.

[0011] Preferably, the fixing rods are spaced apart in the circumferential direction of the mounting shaft, and the wiping plates on the mounting shaft and the protrusions on the matching roller shaft contact and wipe each other and rotate with a common multiple not equal to 1, so that the wiping plates completely wipe each protrusion on the roller shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention adopts a special texture anti-skid structure on the roller. The roller is processed and manufactured with a special process. Due to its special concave-convex structure, it can stably transport the workpiece when quenching during transfer.

[0014] The present invention adopts a direct connection method. The transmission between the power transmission main shaft and the roller shaft uses direct gear transmission to prevent power loss. Indirect transmission methods such as chains and belts are prone to power loss. The rigid direct connection method of gears significantly reduces energy loss in the transmission link and avoids the risk of power interruption caused by slippage, loosening or breakage of transmission components. Therefore, serious equipment failures such as stagnation of the turning action and interruption of transportation caused by power transmission failure are completely eliminated, ensuring the continuous, efficient and trouble-free operation of the production line.

[0015] The present invention adopts a special high-temperature and anti-coking bearing support structure. This structure not only selects special bearing materials that can withstand extremely high temperatures, but also carries out targeted optimization in the bearing's sealing form, lubrication method and heat dissipation channel. Its core goal is to prevent the grease inside the support bearing from deteriorating and carbonizing at high temperatures, and forming hard coke on the bearing raceway and rolling elements. This fundamentally solves the problem of bearing blocking and ensures that the entire turnover conveying mechanism can operate continuously for a long time, stably and with low maintenance under high-temperature oil smoke conditions.

[0016] The wiper of the present invention can wipe the protrusion driven by the mounting shaft, taking away the oil stains or transferring them to a position not in contact with the workpiece, thereby better ensuring the stability of the roller conveying the product;

[0017] The wiping board of the present invention can be folded and attached, thereby avoiding the pollution of oil smoke in the non-wiping stage and maintaining a relatively clean state for working wiping. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The present invention provides a technical solution: a high-temperature flip conveyor mechanism for a furnace, comprising a fixed conveyor frame 1 fixed on an equipment frame, the flip conveyor frame 2 and the fixed conveyor frame 1 can be rotated at an angle of about 90 degrees, that is, the flip conveyor frame 2 can be horizontally flush with the fixed conveyor frame 1, or can be rotated upward 90 degrees to be vertical. This method can reduce the volume of the overall setting, and the furnace door and the flip conveyor frame 2 share the space. When horizontal, the flip conveyor frame 2 and the fixed conveyor frame 1 form an integral conveyor, filling the gap between the heating chamber and the quenching chamber. The fixed conveyor frame 1 and the flip conveyor frame 2 have basically the same structure, both of which are composed of two opposing support frames 3 and a plurality of rollers 4. The two ends of the rollers 4 are respectively rotatably mounted on the support frames 3 with bearings. The axes of each roller 4 are parallel. One end of the roller 4 slightly extends beyond the support frame 3 at that end, and a gear is fixedly sleeved on the extension section. A transmission gear meshing with the gear on the extension section is also rotated on the support frame 3 where the extension section is located, so that each roller 4 is synchronized and rotates in the same direction.

[0036] See Figure 1The product is fed into the heating chamber through the feeding structure, and a conveyor chain is set in the heating chamber. After the product is heated, the furnace door on the outlet side is opened, and the conveyor chain in the heating chamber is started to output the product. The quenching chamber is set corresponding to the outlet side of the heating chamber to quench the product, and the flip conveying mechanism is set between the heating chamber and the quenching chamber.

[0037] The difference between the flip conveyor frame 2 and the fixed conveyor frame 1 is that, in terms of the axial length of the roller shaft 4, the length of the roller shaft 4 on the fixed conveyor frame 1 is greater than the length of the roller shaft 4 on the flip conveyor frame 2. There is an overlapping area between the flip conveyor frame 2 and the fixed conveyor frame 1. In this area, the two share the same roller shaft 4. The roller shaft 4 is the main shaft 4', which is the power input shaft. The main shaft 4' extends outward at one end close to the transmission gear and passes through the support frame 3 on the fixed conveyor frame 1 and is connected to the power source. The power source can be directly driven by a motor or through other transmissions. The main shaft 4' drives the other rollers 4 to rotate synchronously through gears. At the other end opposite to the extended end of the main shaft 4', its end is flush with the support frame 3 at that end, and a flip shaft 5 is coaxially arranged at the axial end. The flip shaft 5 is installed on the support frame 3 of the fixed conveyor frame 1 through a bearing, one end is fixed to the adjacent support frame 3 on the flip conveyor frame 2, and the other end extends to the outside of the fixed conveyor frame 1 and is connected to the power source. The flip shaft 5 is used to change the state of the flip conveyor frame 2, making it horizontal or vertical, and switching between the two states to realize product transportation.

[0038] Each roller 4 is provided with a radially outward protrusion 6, which adopts a specially designed concave-convex texture anti-slip structure to prevent the product from slipping on the surface of the roller 4, especially in a high temperature, high humidity, and heavy oil smoke environment with oil deposition. After the oil is deposited, the contact surface between the roller 4 and the product is in a slippery state, making it impossible to transport the product stably. The outward protrusion 6 can increase the local pressure, and at the same time the oil is deposited in the recessed area between the protrusions 6, thereby reducing the impact on the conveying stability of the roller 4.

[0039] See Figure 6 The bearing between the roller 4 and the support frame 3 adopts an open structure, that is, no retaining frame is used. The open structure allows the oil smoke in the equipment to enter it and contact with the rolling elements to form a lubricating effect. According to my country's bearing standards, the radial clearance of rolling bearings is subdivided into five levels in the industry to adapt to different application requirements, specifically C0, C1, C2, C3 and C4. The standard clearance corresponding to level C0, C1 and C2 are small clearance bearings, and C3 and C4 are large clearance bearings. The bearings in this solution use large clearance bearings, which can automatically discharge the carbonized blocks inside the bearings as the rolling elements rotate, preventing the equipment from shutting down due to carbonization and coking of the bearings, thereby ensuring the stable operation of the equipment.

[0040] See Figure 7 and Figure 8 When the protrusions 6 are set, because they cannot be as continuous as a complete circle, the product has a smaller range of fluctuations. The smaller the gap between adjacent protrusions 6, the smaller the horizontal height fluctuation of the product. The smaller the gap between adjacent protrusions 6, the smaller the overall gap is. Therefore, in the circumferential direction of the surface of the roller 4, the protrusions 6 are arranged in adjacent circular arrays, and in the axial direction of the roller 4, they are staggered and not arranged in a linear array along the axial direction, that is, the protrusions 6 at the same axial position form a ring, and there is an angle difference between the two adjacent rings. This method uses the protrusions 6 on different rings to compensate for the small-scale ups and downs of the product caused by the spacing between the two adjacent protrusions 6 in the same ring.

[0041] See Figure 8 and Figure 9 The protrusion 6 on the surface of the roller 4 is conical, and the cross-sectional area decreases radially outward on the surface of the roller 4. Specifically, as one embodiment, a cone is adopted. As another embodiment, the protrusion 6 can also be set as a conical tetrahedron, that is, it extends from a fixed point to the surface of the roller 4 in an inclined plane. For the convenience of processing, the vertex of the conical protrusion 6 should not form a negative angle inclined plane, that is, the radial projection of the vertex is not within the bottom range of the protrusion 6. It is preferably symmetrically arranged.

[0042] See Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 15 As the roller 4 continues to work, the accumulation of oil and dirt will still form a smooth surface on the top of the protrusion 6, which will cause the product to be unstable, offset or slip. Therefore, a mounting shaft 7 is set between the two adjacent rollers 4. The two ends of the mounting shaft 7 are also rotatably connected to the support frame 3. Because the mounting shaft 7 does not need to be subjected to force, the ends can be installed with very small bearings to avoid affecting the end strength of the roller 4. The mounting shaft 7 is also connected to the roller 4 by gears, and the rotation direction is opposite to the rotation direction of the roller 4 during transportation. A fixed rod 8 extending radially outward is set on the surface of the mounting shaft 7. The outer end of the fixed rod 8 is hinged to the wiper plate 9. An elastic reset member such as a torsion spring is set at the hinge between the two to make the wiper plate 9 in an unstressed state as shown in the figure. Figure 10 In the inclined state, before the fixing rod 8 on the mounting shaft 7 rotates to the position closest to the surface of the adjacent roller shaft 4, the wiping plate 9 fits the surface of the protrusion 6, and as the roller shaft 4 and the mounting shaft 7 move in the synchronous direction, the wiping plate 9 will form a wiping action at the end area of ​​the protrusion 6 to clean the oil stains. The working surface of the wiping plate 9 can be made of high-temperature resistant non-oleophobic material so that the oil stains can be better removed.

[0043] As one example, Figure 13As shown, the cross section of the wiper 9 can be straight, and during the movement, the inclined surface position of the protrusion 6 can be completely fitted. In this case, the preferred protrusion 6 is a symmetrical inverted four-sided structure, and point contact is formed at the end point to form wiping. As another embodiment, Figure 12 As shown, the cross section of the wiper 9 may also be arc-shaped, and the curvature of the arc of the cross section is smaller than the curvature of the cross section curve of the protrusion 6, so that the entire end surface can be wiped to prevent the product from slipping.

[0044] Furthermore, the fixing rod 8 is configured to be elastically retractable along its own axial direction, and the change in its length can better cooperate with the wiping plate 9 to fit the surface and end point of the wiping protrusion 6.

[0045] Because the wiping plate 9 needs to fit the protrusion 6 for wiping, if the rings formed by the protrusions 6 on the same axial direction of the roller shaft 4 are staggered too much, that is, the same ring is staggered with the two adjacent rings, the wiping plate 9 in the axial direction of the installation shaft 7 cannot be continuous, but requires a separate individual, so the setting is relatively complicated. Therefore, the setting is simplified. The rings formed by the protrusions 6 on the same axial direction of the roller shaft 4 form adjacent staggered, and the same interval setting, that is, one of the rings is staggered with the adjacent rings at an angle difference, and is axially translated with the ring in the interval. The interval here can also be two rings, that is, ring 1, ring 2 and ring 3 are staggered, and are translated with ring 4, ring 5 and ring 6. The specific setting depends on the size and depth of the protrusion 6. In this case, the wiping plate 9 can form a long strip that is continuous along the axial direction of the installation shaft 7 and connected by multiple fixing rods 8.

[0046] See Figure 14 The wiper plate 9 is composed of two parts. The first plate body 91 is axially connected to the outer end of the fixed rod 8, and the two are arranged to rotate within a range through a torsion spring. The second plate body 92 is axially connected to the first plate body 91. Similarly, the second plate body 92 and the first plate body 91 are also arranged to rotate within a range through a torsion spring. The torsion force of the torsion spring between the first plate body 91 and the fixed rod 8 is greater than that between the second plate body 92 and the first plate body 91. That is, under the same material and spiral parameters, the diameter of the wire of the torsion spring between the first plate body 91 and the fixed rod 8 is larger, or the diameter and spiral parameters are larger. When the numbers are completely consistent, the elastic coefficient of the material of the torsion spring between the first plate 91 and the fixing rod 8 is larger. In the axial section, the length of the second plate 92 exceeds that of the first plate 91, so that when the roller shaft 4 and the mounting shaft 7 rotate, the protrusion 6 contacts the free end side of the second plate 92, and opens the second plate 92 while continuing to rotate so that it does not fit the first plate 91. When the rotation continues, it is wiped. This setting is to prevent the wiping surfaces of the first plate 91 and the second plate 92 from being directly affected by the oil fume environment in the equipment, and they are only opened for wiping in the wiping state.

[0047] One mounting shaft 7 can be used to wipe an adjacent roller 4, or two adjacent rollers 4 at the same time, and the slippage of the roller 4 surface during the conveying of products is mainly caused by the accumulation of oil stains. Therefore, the wiping of the protrusion 6 does not need to be done once a circle, but can be done after a certain interval of time, that is, Figure 7 In the state shown, for example, if there are 12 protrusions 6 on the circumference, when the mounting shaft 7 rotates, they cannot be wiped one by one, nor can they be wiped at fixed intervals of 2, 3, 4, 6 or 12, which will cause other protrusions to be missed. Intervals of 5, 7 or 8, etc. can be used. Taking interval 5 as an example, the protrusions are divided into 1-12 in the circumferential direction, and the three protrusions 6 of 1, 5 and 10 are wiped in sequence. When the rotation is continued, the second circle is carried out, and 3 (that is, 15) and 8 (that is, 20) are wiped. The third circle is 2 (that is, 25), 7 (that is, 30) and 12 (that is, 35), and so on, until 60, that is, 5 circles, are formed to overlap and start the cycle. In the above state, repeated wiping can be performed in one cycle, but no omissions can be made. As a better option, there is no repetition or omission in one cycle, so as to avoid the need for replacement of the wiping plate 9 due to repeated wiping of each one, and also to avoid the impact of the wiping plate 9 on the protrusions 6 in an environment with light oil smoke due to multiple contacts in a short period of time.

[0048] After the heating chamber is ready to discharge, the furnace door is opened, and the conveyor chain in the furnace is driven to convey the products. The conveying device between the heating chamber and the quenching chamber is flipped, and the flip conveyor frame 2 is flipped 90° to a horizontal state. The main shaft 4' drives the conveyor product. After the product is conveyed into the quenching chamber, the flip conveyor frame 2 is flipped 90° to a vertical state. The furnace door can be lowered and closed, and the heating chamber is used to heat another batch of products. When the flip conveyor frame 2 and the fixed conveyor frame 1 are conveying products, when the roller 4 rotates, the wiping plate 9 wipes the surface of the protrusion 6 to prevent it from slipping due to oil stains.
