Description

Technical Field

[0001] This application relates to the field of bearing roller conveying, and in particular to a roller quantitative feeding device. Background Technology

[0002] As an indispensable component in mechanical operation, the machining quality of the rollers in bearings directly affects the performance and stability of the bearings. During the machining process, the rollers undergo machining processes such as turning and grinding before entering the heat treatment process to improve their hardness and wear resistance. Traditional heat treatment processes include loading, preheating, high-temperature heating, quenching and tempering, and unloading. Preheating, located at the beginning of the drying tunnel, requires the rollers to be evenly distributed within the tunnel to avoid insufficient or excessive preheating in certain areas, which would affect the uniformity of the microstructure during subsequent quenching. In the traditional loading process for bearing rollers during heat treatment, there are two common methods. One is to manually pour the rollers from the turnover box into the inlet of the heat treatment drying tunnel; the other is to move the turnover box above the inlet of the drying tunnel, with a discharge port at the bottom of the turnover box, allowing the rollers to fall into the drying tunnel by gravity. These two methods meet basic production needs to a certain extent, and the second method does not require additional complex power equipment. However, existing roller loading methods have significant drawbacks. On the one hand, both methods require manual installation of the rollers at the inlet of the drying tunnel, making them highly dependent on manual labor and prone to having too many or too few rollers during the installation process. On the other hand, when the front and rear turnover hoppers are being replaced, or if material jams occur and are not cleared in time, some sections of the drying tunnel may not have rollers installed, resulting in wasted energy. Overall, the labor cost is high, and uneven roller installation can affect the stability of the heat treatment effect, thereby affecting the quality stability of the roller heat treatment. Summary of the Invention

[0003] The purpose of this application is to overcome the above-mentioned technical problems and provide a roller quantitative feeding device.

[0004] A roller metering feeding device includes a hopper and a first bracket for supporting the hopper. A first vibrator is installed at the bottom of the hopper, and a discharge port is provided at the bottom of the hopper. The device further includes a first feed channel, a metering device, and a second feed channel. The first and second feed channels are arranged sequentially along the roller conveying direction and are both inclined.

[0007] Preferably, a rotating block is connected to one end of the baffle plate, and the rotating block is rotatably connected to the side wall of the first material channel. The flipping drive drives the rotating block to rotate, thereby causing the baffle plate to rotate at the first outlet. When the baffle plate rotates to the direction of the bottom extension line of the first material channel or below the extension line, the first outlet achieves the material passage state. When the baffle plate rotates to the top of the bottom extension line of the first material channel, the first outlet achieves the material blocking state.

[0008] Preferably, the hopper is further provided with an anti-jamming mechanism, including a turntable, a turntable motor for driving the turntable to rotate, and a discharge guide channel. The top surface of the turntable is flat and located below the discharge port. The discharge guide channel is suspended above the turntable. The distance between the bottom end of the discharge guide channel and the top surface of the turntable is smaller than the outer diameter of the roller to be conveyed, so that the roller falling onto the turntable is limited to moving within the discharge guide channel. One end of the discharge guide channel receives the discharge port and is fixedly connected to the hopper, and the other end is set as a discharge port and extends out of the outer edge of the turntable. The first inlet of the first material channel is located below the anti-jamming mechanism and receives the discharge port.

[0009] Preferably, the discharge guide channel includes two baffles spaced apart and vertically arranged, the two baffles being located above the turntable, one end of each of the two baffles being fixedly connected to the hopper, and the other end of each of the two baffles extending towards the first material channel and extending beyond the outer edge of the turntable, with a flexible plate provided on the inner side of each baffle facing the discharge guide channel, the gap between the bottom of the flexible plate and the top surface of the turntable being smaller than the distance between the bottom end of the baffle and the top surface of the turntable.

[0012] Preferably, the first material channel includes an inclined base plate and side plates fixed to both sides of the base plate. The first inlet is located at the higher end of the base plate. A blocking block is provided between the end of the side plate near the hopper and the outer wall of the baffle. The blocking block is fixedly connected to the side plate and suspended on the turntable. A sponge block is detachably fastened between the blocking block and the outer wall of the baffle. The bottom of the sponge block contacts the top surface of the turntable.

[0013] Preferably, the quantitative feeding device further includes a conveying buffer platform, which includes a third support, an inclined third material channel, and a third vibrator installed at the bottom of the third material channel. The third material channel is installed on the third support through an elastic support member. The higher end of the third material channel is set as the third inlet, and the lower end is set as the third outlet. The third inlet is connected to the second outlet of the second material channel. A guide member is provided inside the third material channel.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. The first and second material channels are inclined and arranged in sequence, so that the rollers to be conveyed enter the first material channel from the hopper outlet, then enter the second material channel through the metering device, and finally feed to the inlet of the drying tunnel. The weighing mechanism of the metering device can weigh and quantify the rollers. With the material passing and blocking functions of the material blocking component, the rollers are quantitatively fed, reducing the amount of manual roller laying, improving the uniformity of roller laying, and enhancing the stability of heat treatment effect.

[0016] 2. By setting up an anti-jamming mechanism, the rollers after the material is discharged from the hopper can be continuously conveyed, effectively preventing the rollers from accumulating and jamming near the discharge port in the hopper, and reducing manual intervention;

[0017] 3. By setting up a conveyor buffer platform, the rollers output from the second material channel can be further buffered. The third vibrator can assist the rollers to move in the third material channel, and the guide can guide and unblock the rollers, ensuring the uniformity of subsequent conveying of the rollers.

[0028] The following will be combined with the appendix Figure 1-9 The technical solutions in the embodiments of the present invention will be described in further detail below. (See references.) Figure 1 and Figure 2As shown in the embodiment of this application, the roller quantitative feeding device is installed at the inlet of the heat treatment drying tunnel. The roller quantitative feeding device includes a hopper 1, a first support 12, a first material channel 2, a quantitative device 3, and a second material channel 4. The hopper 1 is installed on the first support 12, and a discharge port 11 is provided at the bottom of the hopper 1. The first material channel 2 and the second material channel 4 are arranged inclined in sequence along the roller conveying direction. The higher end of the first material channel 2 is designated as the first inlet 21, and the lower end is designated as the first outlet 22. The higher end of the second material channel 4 is designated as the second inlet 41, and the lower end is designated as the second outlet 42. The first inlet 21 receives the discharge port 11 of the hopper 1, and the second inlet 41 receives the first outlet 22 of the first material channel 2. The metering device 3 is set at the first outlet 22, and the second outlet 42 is connected to the inlet of the front section of the drying tunnel. The rollers to be conveyed are stored in the hopper 1. The rollers are discharged from the discharge port 11, pass through the first material channel 2 and the second material channel 4 in sequence, and are conveyed to the front section of the drying tunnel from the second outlet 42. The setting of the metering device 3 realizes the quantitative feeding of the rollers, avoids problems such as uneven manual laying and material jamming, improves the feeding efficiency of the heat treatment process, and improves the quality stability of the roller heat treatment.

[0029] For details, please refer to Figure 1 and Figure 2 The first support 12 is placed on the ground to support the hopper 1. Four sets of support components 13 are located at the four corners of the top of the first support 12. Each support component 13 includes a support block 131 and four legs 132. The support block 131 is fixedly installed on the top of the first support 12, and the four legs 132 are arranged in pairs on both sides of the hopper 1 and fixed to the outer wall of the hopper 1. Each leg 132 abuts against the top of the four support blocks 131, and the legs 132 are welded to the side wall of the hopper 1 to ensure a strong connection. A first vibrator (not shown in the figure) is installed at the bottom of the hopper 1. In this embodiment, the first vibrator is preferably a vibrating motor, which is directly installed and fixed at the bottom of the hopper 1. The first vibrator vibrates the hopper 1, causing the roller to move towards the discharge port 11 by the combined action of its own weight and vibration, so that the roller in the hopper 1 continuously drops material. In order to cooperate with the vibration of the hopper 1, the support block 131 can be made of rubber material, which provides good elastic support for the hopper 1.

[0030] The hopper 1 is also equipped with an anti-jamming mechanism 15, which includes a turntable 151, a turntable motor 152 that drives the turntable 151 to rotate, and a discharge guide channel 153. The top surface of the turntable 151 is set as a plane and is located below the discharge port 11. The distance between the top surface of the turntable 151 and the bottom surface of the hopper 1 is less than the outer diameter of the roller to be conveyed. The turntable 151 is rotatably mounted on the first bracket 12. The turntable motor 152 is connected to the turntable 151 by belt drive or gear drive, so that the turntable motor drives the turntable 151 to rotate. In this embodiment, the transmission method is preferably gear drive (not shown in the figure). The discharge guide channel 153 is set above the turntable 151. One end of it receives the discharge port 11 and is fixedly connected to the hopper 1, and the other end is set as a discharge port and extends out of the outer edge of the turntable 151. The discharge guide channel 153 includes two baffles 1531 spaced apart and vertically arranged. One end of each baffle 1531 is fixed to the hopper 1 by welding or bolting, preferably by welding in this embodiment; the other end extends toward the first material channel 2 so that the discharge port extends beyond the outer edge of the turntable 151. To prevent the rollers from entering the gap between the bottom end of the baffle 1531 and the top surface of the turntable 151, the gap is smaller than the outer diameter of the conveying rollers. A flexible plate 1532 is vertically installed on the inner side of each baffle 1531 facing the discharge guide channel 153. The flexible plate 1532 is attached to the baffle 1531 and fixedly connected by screws. The gap between the bottom end of the flexible plate 1532 and the top surface of the turntable 151 is smaller than the gap between the bottom end of the baffle 1531 and the top surface of the turntable 151. In another embodiment, the bottom end of the flexible plate 1532 contacts the top surface of the turntable 151, which can further limit the roller within the discharge guide channel 153. The flexible plate 1532 can be made of materials such as rubber or silicone, and has flexibility. Since there are impurities such as iron filings in the machined roller, the flexible plate 1532 can effectively prevent iron filings and other impurities from getting stuck in the gap between the bottom of the baffle 1531 and the top surface of the turntable 151, preventing malfunctions between the turntable 151 and the baffle 1531.

[0031] Furthermore, a rectangular side hole 14 is provided on the side wall of the hopper 1 facing the first material channel 2, which communicates with the bottom discharge port 11 of the hopper 1. The ends of the two baffles 1531 are fixedly connected to the two sides of the side hole 14. The side hole 14 can expand the discharge area, making it easier for the roller to come out of the hopper 1 and improving the discharge efficiency.

[0032] refer to Figure 1 and Figure 2 To further improve the discharge efficiency of hopper 1, two discharge ports 11 are provided at the bottom of hopper 1, and an anti-jamming mechanism 15 is provided below each discharge port 11. At the same time, two side holes 14 are provided on the side wall of hopper, which are respectively connected to the two discharge ports 11.

[0033] Combination Figure 3and Figure 4 A second support 24 and a second vibrator 25 are provided below the first material channel 2. The second support 24 is placed on the ground, and the second vibrator 25 is installed on the top of the second support 24. The first material channel 2 is fixedly connected to the top of the second vibrator 25. The second support 24 provides support for the second vibrator 25, and the second vibrator 25 provides vibration to the first material channel 2. In this embodiment, the second vibrator 25 is preferably a linear vibrator, which can further assist the rollers in the first material channel 2 to move smoothly from high to low, thereby improving the roller conveying efficiency.

[0034] Furthermore, the first material channel 2 is inclined, and the first inlet 21 of the first material channel 2 extends below the turntable 151 and receives the discharge port of the discharge guide channel 153, which ensures that the rollers fall accurately into the first material channel 2. The first material channel 2 includes an inclined base plate 26 and side plates 27 fixed on both sides of the base plate 26. A blocking block 28 is provided between the end of the side plate 27 near the hopper 1 and the outer wall of the baffle 1531. The blocking block 28 is fixedly connected to the side plate 27 and extends above the turntable 151. A sponge block 29 is detachably fastened between the blocking block 28 and the outer wall of the baffle 1531. The bottom of the sponge block 29 contacts the top surface of the turntable 151. Since the baffle 1531 vibrates with the hopper 1 under the action of the first vibrator, and the side plate 27 vibrates with the action of the second vibrator 25, there is usually a large gap between the outer wall of the baffle 1531 and the end of the side plate 27. This makes it easy for the roller to fall out of the gap during the vibration conveying process of the first material channel 2. Therefore, the blocking block 28 can effectively prevent the roller from falling out of the gap between the outer wall of the baffle 1531 and the end of the side plate 27. The sponge block 29 forms soft friction, which can make the gap zero and effectively prevent the roller from falling out of the gap. In addition, the roller surface is coated with cutting fluid after the machining of the previous processes. When the roller falls from the discharge port 11 onto the turntable 151, some of the fluid will remain on the top surface of the turntable 151. As the turntable 151 rotates, the fluid will be thrown out of the equipment from the edge of the turntable 151, affecting the environment. Therefore, the sponge block 29 has an adsorption function, which can prevent the fluid on the surface of the turntable 151 from being thrown out of the equipment. When the sponge block 29 is full of fluid, it can be replaced, thus improving the working environment.

[0035] Combined Figure 1 and Figure 4The second material channel 4 is inclined at a greater angle than the first material channel 2. The second inlet 41 is located below the first outlet 22 of the first material channel 2 and receives the rollers falling from the first material channel 2. Mounting plates 43 are fixedly connected to both sides of the higher end of the second material channel 4. Mounting seats 44 are fixedly installed on the second bracket 24. The mounting plates 43 and mounting seats 44 are connected and fixed. After the first material channel 2 receives the rollers falling from the discharge port, the rollers can be evenly distributed in the first material channel 2 under the action of the second vibrator 25 because the slope of the first material channel 2 is relatively gentle. The slope of the second material channel 4 is greater than that of the first material channel 2, which can improve the conveying speed of the subsequent rollers.

[0036] Specifically, in combination Figure 1 , Figures 4 to 6 The quantitative device 3 includes a baffle assembly 5 and a weighing mechanism 6. The baffle assembly 5 includes a baffle plate 51 disposed at the first outlet 22 and a flipping drive 52 that drives the baffle plate 51 to flip, so that the first outlet 22 is in a material-passing or material-blocking state. The baffle plate 51 is located above the second material channel 4 and is a rectangular plate whose length is adapted to the width of the first material channel 2. A rotating block 53 is fixedly connected to one end of the baffle plate 51 along its length. The rotating block 53 extends along the width of the baffle plate 51 and is provided with a connecting part 531. A rotating shaft 54 ​​is disposed below the bottom plate 26 at the first outlet 22. The two ends of the rotating shaft 54 ​​are fixedly connected to the side plates 27 on both sides of the first material channel 2 through a first connecting plate 55. A connecting sleeve 56 is fixedly connected to the long side of the baffle plate 51 and is fitted onto the rotating shaft 54. The baffle plate 51 can rotate around the rotating shaft 54. The rotating block 53 is provided with a rotating hole. The end of the rotating shaft 54 ​​extends out of the first connecting plate 55 and is movably installed in the rotating hole. The flipping drive 52 is a cylinder or a hydraulic cylinder. In this embodiment, it is preferably a cylinder, defined as a flipping cylinder 57. The cylinder body of the flipping cylinder 57 is fixed to the outside of the side plate 27 of the first material channel 2. The piston rod is set vertically. The end of the rotating block 53 away from the baffle plate 51 is movably connected to the piston rod. The piston movement of the flipping cylinder 57 can drive the rotating block 53 and the baffle plate 51 to rotate around the rotating shaft 54. When the baffle plate 51 rotates to the direction of the extension line of the bottom plate 26 of the first material channel 2 or below the direction of the extension line, the rollers on the first material channel 2 can fall from the first outlet 22 onto the baffle plate 51. Then the rollers pass through the baffle plate 51 and are sent into the weighing mechanism 6, which is in the material passing state. When the baffle plate 51 rotates to the direction of the extension line of the bottom plate 26 of the first material channel 2, the rollers on the first material channel 2 are blocked when they reach the first outlet 22, which is in the material blocking state. In this embodiment, when the material blocking state is in the material blocking state, the baffle plate 51 is perpendicular to the bottom plate 26 to achieve the best material blocking effect.

[0037] In another embodiment, reference Figure 5As shown, the baffle plate 51 can also be composed of two parallel plates, namely a first plate 511 and a second plate 512. A connecting sleeve 56 is fixedly connected to one side of each of the first plate 511 and the second plate 512. The two connecting sleeves 56 are sequentially fitted onto the rotating shaft 54. A rotating block 53 is fixedly connected to the outer side of each of the first plate 511 and the second plate 512. Each rotating block 53 is correspondingly connected to a tilting drive component 52, which is a tilting cylinder 57. The first plate 511 and the second plate 512 drive the rotating block 53 to rotate independently through their respective tilting cylinders 57. Simultaneously, material separators 513 are fixedly installed on adjacent sides of the first plate 511 and the second plate 512. The baffle plate 51, composed of the first plate 511 and the second plate 512, can adjust the conveying capacity of the first outlet 22 according to the amount of roller conveying.

[0038] The weighing mechanism 6 includes a weighing hopper 61, a discharging assembly 62, a weighing scale 63, and a weighing support 64. The weighing support 64 is located below the second material channel 4, and the weighing scale 63 is mounted on top of the weighing support 64. The weighing scale 63 has a weighing platform 631 on its top. The weighing hopper 61 is mounted on the weighing platform 631 via a connecting bracket 65. The supporting installation via the connecting bracket 65 ensures that the weighing hopper 61 is located above the second material channel 4. The weighing hopper 61 is a rectangular frame with openings at the top and bottom. Its length is arranged along the width of the second material channel 4. The opening at the top of the weighing hopper 61 receives the first outlet 22. A baffle plate 51 is located above the weighing hopper 61. When the baffle plate 51 is in the material-passing state, the end of the baffle plate 51 away from the first outlet 22 is also located above the opening at the top of the weighing hopper 61. During roller conveying, the material enters from the first outlet 22 into the baffle plate 51 and then falls from the baffle plate 51 into the weighing hopper 61. The opening at the lower end of the weighing hopper 61 is set as a discharge port 66. The discharge port 66 is located above the second inlet 41 of the second material channel 4. The discharge port 66 can be closed or opened by the pouring component 62. When the discharge port 66 is open, the rollers in the weighing hopper 61 fall into the second inlet 41 of the second material channel 4, and then continue to be conveyed through the second material channel 4.

[0039] The connecting bracket 65 includes a lower support 651, a support rod 652, and an upper support 653. The lower support 651 extends outwards from both sides of the second material channel 4. Two support rods 652 are provided, located on both sides of the second material channel 4 and vertically fixed to both ends of the lower support 651. Two upper supports 653 are provided, located at both ends of the weighing hopper 61 and fixedly connected to the outer walls of both ends of the weighing hopper 61. The end of the upper support 653 furthest from the weighing hopper 61 is fixedly connected to the top of the support rod 652 on that side by bolts. In another embodiment, as shown in the reference... Figure 8 To improve the support stability of the weighing hopper 61, two sets of connecting brackets 65 are provided, spaced apart along the width direction of the weighing hopper 61.

[0040] The material discharge port 66 of the weighing hopper 61 is rectangular along the length of the weighing hopper 61. The material pouring assembly 62 includes a receiving plate 621 and a material pouring drive 622. The receiving plate 621 covers the material discharge port 66 and is hinged to the weighing hopper 61 on one side. The material pouring drive 622 is connected to the receiving plate 621 in a transmission manner. The weighing scale 63 and the material pouring drive 622 are both connected to the control system by electrical signals. When the roller on the weighing hopper 61 reaches a certain weight, the control system sends a signal to the material pouring drive 622 to drive the receiving plate 621 to rotate and open the material discharge port 66.

[0041] In another embodiment, the receiving plate 621 is composed of two rectangular plates, namely a third plate 6211 and a fourth plate 6212. The third plate 6211 and the fourth plate 6212 are arranged side by side along the width direction of the weighing hopper 61 to form the receiving plate 621 corresponding to the discharge port 66. Each end of the third plate 6211 and the fourth plate 6212 is fixedly connected to a second connecting plate 623. The opposite ends of the two second connecting plates 623 on the same side are rotatably connected to the outer wall of the weighing hopper 61. The opposite ends of the two second connecting plates 623 are respectively connected to the pouring drive 622. The pouring drive 622 includes a pouring cylinder 6221, a first rod 6222, a second rod 6223, and a third rod 6224. The cylinder body of the pouring cylinder 6221 is fixedly connected to the outer wall of the weighing hopper 61. The piston rod of the discharge cylinder 6221 is fixedly connected to the first rod 6222. The first rod 6222 is rotatably connected to the second rod 6223 and the third rod 6224 around the same axis. The ends of the second rod 6223 and the third rod 6224 away from the first rod 6222 are rotatably connected to two second connecting plates 623 on the same side. When the third plate 6211 and the fourth plate 6212 close the discharge port 66, the second rod 6223 and the third rod 6224 form an inverted V shape. When the piston rod of the discharge cylinder 6221 moves downward, the first rod 6222 drives the second rod 6223 and the third rod 6224 to move downward, and at the same time, the second connecting plates 623 are linked, causing the third plate 6211 and the fourth plate 6212 to rotate in opposite directions downward, thereby opening the discharge port 66. To ensure the stability of the rotation of the third plate 6211 and the fourth plate 6212, a material pouring drive 622 is also provided at both ends of the weighing hopper 61.

[0042] Furthermore, in another embodiment, in order to further ensure that the rollers are fed more evenly to the drying tunnel inlet, combined with Figure 9As shown, the roller quantitative feeding device also includes a conveying buffer platform 7, which is located between the second outlet 42 and the inlet of the drying tunnel. The conveying buffer platform 7 includes a third support 71, a third material channel 72, and a third vibrator (not shown in the figure) installed at the bottom of the third material channel 72. The third material channel 72 is installed on the third support 71 through an elastic support member 74. The third material channel 72 is inclined, with the higher end being the third inlet 721 and the lower end being the third outlet 722. The third inlet 721 is located below the second outlet 42 of the second material channel 4. The third vibrator is preferably a vibrating motor. When the vibrating motor is working, it can drive the third material channel 72 to vibrate on the third support 71, thereby improving the sequential conveying of the rollers on the third material channel 72 without material accumulation. Specifically, four elastic support members 74 are provided, respectively located at the four corners of the top of the third bracket 71. Each elastic support member 74 includes a fixed support 741, a spring 742, and a fixing block 743. The fixed support 741 is fixedly connected to the top of the third bracket 71. The top of the fixed support 741 protrudes upward to form a guide post. The spring 742 is fitted onto the outside of the guide post. The fixing block 743 is fixed to the outer wall of the third material channel 72 by welding. The upper end of the spring 742 is welded to the fixing block 743. The spring 742 is preferably a compression spring 742. The axial length of the guide post is less than the axial length of the spring 742. Furthermore, a guide element 73 is provided at the bottom of the inner conveying rollers of the third material channel 72. The guide element 73 is a V-shaped guide bar 731, and multiple guide elements can be provided. The pointed part of the V-shaped guide bar 731 faces the direction of the third inlet 721. The guide element 73 can also be a straight guide bar 732, and its length direction is set at an angle with the conveying direction of the rollers. When the rollers are vibrating and conveyed on the third material channel 72, the guide element 73 can further guide the rollers. Furthermore, the third material channel 72 is made of steel, and the guide element 73 is made of magnetic material. The guide element 73 and the third material channel 72 are connected by magnetic adsorption. Moreover, the position of the guide element 73 can be adjusted according to different roller models, thereby guiding the rollers to be conveyed more orderly and further improving the stability of feeding.

[0043] The implementation principle of this embodiment is as follows: After machining, the rollers are transferred to the hopper 1. The rollers fall from the discharge port 11 in the hopper 1 onto the rotating turntable 151, and then enter the discharge guide channel 153. The rotation of the turntable 151 drives the rollers to move towards the outer edge of the turntable 151 while simultaneously limiting their movement within the discharge guide channel 153. Then, the rollers fall from the discharge port into the first material channel 2 below. Under the action of gravity and the vibration of the second vibrator 25, the rollers in the first material channel 2 continue to move towards the first outlet 22. The flipping drive 52, the pouring drive 622, and the weighing scale are all connected to the control system via electrical signals. When the baffle plate 51 at the first outlet 22 is in the material-passing state, the rollers fall from the first outlet 22 through the baffle plate 51 into the weighing hopper 61. At this time, the discharge port 66 is in the closed state, and the weighing hopper 61 continuously receives the rollers. The weighing scale 63 weighs the material in real time. When the set weight is reached, the weighing scale 63 sends a signal to the control system. The control system controls the flipping drive 52 to drive the baffle plate 51 to flip, so that the baffle plate 51 at the first outlet 22 is in the material-blocking state. It also controls the pouring drive 622 to drive the receiving plate 621 to rotate and open the discharge port 66. The rollers in the weighing hopper 61 fall into the second material channel 4 and then pass through the conveying buffer table 7 to complete the feeding. In one embodiment where the baffle plate 51 consists of a first plate 511 and a second plate 512, when the weight of the rollers in the weighing hopper 61 approaches the preset weight during real-time weighing by the weighing scale 63, the control system controls the tilting cylinder 57 to drive the first plate 511 to tilt, thus blocking the material. This ensures that the rollers at the first outlet 22 can only be fed onto the weighing hopper 61 from the second plate 512. By adjusting the roller conveying rate, the error between the weight of the rollers in the weighing hopper 61 and the preset weight can be minimized. The entire roller conveying process achieves automated quantitative feeding, reduces manual intervention, improves feeding efficiency and the uniformity of roller laying, and ensures the stability of the roller heat treatment quality.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
