Description

Technical Field

[0001] The present invention belongs to the technical field of energy-saving sheet metal plates, and in particular relates to an energy-saving sheet metal plate roller segmented buffering device. Background Art

[0002] In the modern sheet metal processing industry, roller conveyor systems, as key equipment for sheet metal transport and buffering, are widely used to connect various links in the production line. Traditional roller-type buffering devices typically operate continuously. That is, regardless of whether there is sheet metal on the roller, the roller drive motor continues to operate to ensure that the sheet metal is ready for transport and buffering at any time. This operating mode has many drawbacks. The first is the huge energy consumption. Even when there is no sheet metal to transport, the motor continues to operate at high speed, resulting in a large amount of electrical energy waste, which greatly increases the company's production costs and energy burden.

[0003] However, when existing energy-saving sheet metal plates are being transported, they often need to be cached, most of which are at the turning points. However, although they are cached during the turning process, the energy-saving sheet metal plates may still touch the baffles provided on the conveyor during movement, which may easily cause damage to the energy-saving sheet metal plates. At the same time, when the energy-saving sheet metal plates are being transported on the conveyor, after the energy-saving sheet metal plates collide with the baffles at the turning points on the conveyor, the energy-saving sheet metal plates are often transported by the curvature of the baffles and the conveying force generated by the conveyor. However, they may still make micro-contact with the baffles when leaving the turning points. When leaving the cache section, they are likely to collide with the baffles on the conveyor again in the acceleration section, which may cause damage to the energy-saving sheet metal plates.

[0004] In view of this, the present invention is proposed. Summary of the Invention

At the same time, when the energy-saving sheet metal plates are transmitted on the conveyor, after the energy-saving sheet metal plates collide with the baffles at the turning points on the conveyor, the energy-saving sheet metal plates are often transmitted by the curvature of the baffles and the conveying force generated by the conveyor. However, they may still make micro-contact with the baffles when leaving the turning points.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0021] Example 1: like Figures 1 to 6As shown, an energy-saving sheet metal roller segmented caching device includes a transmission unit 100, a transmission unit 200 and a swing unit 300. The transmission unit 100 includes a conveyor body 101, and an energy-saving sheet metal body 102 is placed above the conveyor body 101; the swing unit 300 includes a rotating rod 3013, a bearing 3014 is provided above the rotating rod 3013, and a second guide plate 3015 is provided at the bottom end of the rotating rod 3013; the transmission unit 200 includes a driving assembly and a mounting plate 2012, a rectangular slot 2013 is provided at the bottom of the mounting plate 2012, and a first guide plate 2021 is provided below the inner cavity of the rectangular slot 2013, the driving assembly is used to drive the mounting plate 2012 to rotate, and the driving assembly is also used to drive the first guide plate 2021 and the mounting plate 2012 to rotate in opposite directions, and the rotation of the first guide plate 2021 is used to drive the second guide plate 3015 to rotate. The driving assembly can drive the active gear 205 to move in a circle. At the same time, because the active gear 205 is meshed with a gear ring 2051, it can ensure that the active gear 205 can also rotate when moving in a circle. When the active gear 205 rotates, it can drive the rotating rod 202 to rotate, and the rotation of the rotating rod 202 can drive the first guide plate 2021 to rotate. Therefore, the rotation of the first guide plate 2021 can push the energy-saving sheet metal plate body 102, so that the trajectory of the energy-saving sheet metal plate body 102 can be changed when it is transmitted on the conveyor body 101. At this time, the speed of the roller on the conveyor body 101 is adjustable and slowed down, and its specific adjustable slowing down is the existing technology, so it is ensured that when the energy-saving sheet metal plate body 102 is transmitted, the energy-saving sheet metal plate body 102 can play a buffering role.

[0022] like Figures 1 to 6 As shown, in a specific embodiment, baffles 1011 are provided on both sides of the conveyor body 101. The bottom of each baffle 1011 is provided with multiple equally spaced support legs 1012. Four mounting brackets 103 are also provided on the outside of the conveyor body 101. A top plate 1031 is provided above the four mounting brackets 103. Three positioning rods 2031 are provided at the bottom of the top plate 1031. A protective housing 203 is provided at one end of the three positioning rods 2031 away from the top plate 1031. In this configuration, the installation position and components of the protective housing 203, as well as the installation position of the top plate 1031, are determined, ensuring that the top plate 1031 will not fall.

[0023] Example 2: The difference between Example 1 and this example is that: Figures 1 to 6As shown, an energy-saving sheet metal roller conveyor segmented buffering device has a drive assembly including a servo motor 201, which is disposed below a top plate 1031. A rotating rod 2011 is disposed at the output end of the servo motor 201. The rotating rod 2011 flexibly extends through a protective housing 203, and a mounting plate 2012 is fixedly connected to the end of the rotating rod 2011 away from the servo motor 201. This arrangement defines the installation position and components of the drive assembly, ensuring that when the servo motor 201 is running, the servo motor 201 will drive the rotating rod 2011 to rotate, and when the rotating rod 2011 rotates, the rotating rod 2011 will also drive the mounting plate 2012 to rotate.

[0024] like Figures 1 to 6 As shown, in a specific embodiment, a rotating rod 202 is disposed above the first guide plate 2021. The rotating rod 202 movably extends through the mounting plate 2012. The rotating rod 202 is provided with a bearing seat 2022 within the rectangular notch 2013. Mounting brackets 2023 are provided at both ends of the bearing seat 2022. The two mounting brackets 2023 are each disposed on the inner wall of the rectangular notch 2013 at one end away from the bearing seat 2022. In this arrangement, because the rotating rod 202 is provided with the bearing seat 2022 and the mounting brackets 2023 are provided on the bearing seat 2022, the rotating rod 202 is prevented from falling.

[0025] like Figures 1 to 6 As shown, further, the rotating rod 202 is movable through the bottom of the protective housing 203, and the end of the rotating rod 202 away from the first guide plate 2021 is rotatably mounted on the inner wall of the protective housing 203. The rotating rod 202 is provided with a driving gear 205 within the inner cavity of the protective housing 203. In this arrangement, the mounting position of the driving gear 205 is determined, ensuring that when the rotating rod 202 moves in a circular motion, it can drive the driving gear 205 to move in a circular motion.

[0026] like Figures 1 to 6As shown, further, a gear ring 2051 is meshed on the driving gear 205, and a plurality of limit rods 2052 are arranged above the gear ring 2051 and distributed in a circle. Each limit rod 2052 is movable through the top of the protective shell 203, and each limit rod 2052 is arranged on the top plate 1031 at one end away from the gear ring 2051. In this arrangement, it is ensured that when the rotating rod 202 moves in a circle, it can drive the driving gear 205 to move in a circle. At the same time, because the driving gear 205 is meshed with a gear ring 2051, it can ensure that the driving gear 205 can also rotate when moving in a circle. When the driving gear 205 rotates, it can drive the rotating rod 202 to rotate, and the rotation of the rotating rod 202 can drive the first guide plate 2021 to rotate. Therefore, the rotation of the first guide plate 2021 can push the energy-saving sheet metal plate body 102, so that the trajectory of the energy-saving sheet metal plate body 102 can be changed when it is transmitted on the conveyor body 101.

[0027] Example 3: The difference between Example 2 and this example is that: Figures 1 to 6 As shown, an energy-saving sheet metal roller conveyor segmented buffering device has a connecting rod 204 disposed on a rotating rod 202. A coupling rod 2042 is disposed at the end of the connecting rod 204 away from the rotating rod 202. An arc-shaped stop plate 2041 is disposed at the bottom of the coupling rod 2042. In this arrangement, the mounting position of the coupling rod 2042 is determined to ensure that when the rotating rod 202 rotates, it also drives the connecting rod 204 to rotate, thereby driving the coupling rod 2042 to move through the connecting rod 204.

[0028] like Figures 1 to 6As shown, in a specific embodiment, a movable groove 2043 is provided at the bottom of the top plate 1031, a movable slider 2044 is slidingly provided in the inner cavity of the movable groove 2043, a connecting rod 2042 is provided at the bottom of the movable slider 2044, a return spring 2045 is provided in the inner cavity of the movable groove 2043, and the other end of the return spring 2045 is provided on the movable slider 2044. In this setting, it is ensured that when the rotating rod 202 rotates, it can also drive the connecting rod 204 to rotate. When the connecting rod 204 rotates, it can push the connecting rod 2042 to move horizontally with the assistance of the moving slide 2043 and the moving slider 2044, thereby driving the arc limit plate 2041 to move, so that the energy-saving sheet metal plate body 102 transmitted on the conveyor body 101 can be blocked and limited by the arc limit plate 2041, avoiding the collision between the energy-saving sheet metal plate body 102 and the baffle 1011. Because the inner cavity of the moving slide 2043 is provided with a reset spring 2045, and the other end of the reset spring 2045 is provided on the moving slider 2044, it is ensured that the moving slider 2044 can be reset, thereby driving the connecting rod 2042 to reset.

[0029] like Figures 1 to 6 As shown, further, a first pulley 301 is provided on the rotating rod 202, a transmission belt 3012 is provided on the first pulley 301, a second pulley 3011 is sleeved on the other end of the transmission belt 3012, and a rotating rod 3013 is fixedly passed through the second pulley 3011. This arrangement ensures that when the rotating rod 202 rotates, it can also drive the first pulley 301 to rotate, when the first pulley 301 rotates, it can drive the second pulley 3011 to rotate through the transmission belt 3012, when the second pulley 3011 rotates, it can drive the rotating rod 3013 to rotate, and when the rotating rod 3013 rotates, it can drive the second guide plate 3015 to rotate, so that one end of the second guide plate 3015 can be close to the side of the baffle 1011.

[0030] like Figures 1 to 6 As shown, a bearing 3014 is further provided at the upper end of the rotating rod 3013, and the bearing 3014 is disposed on the top plate 1031. A second guide plate 3015 is provided at the end of the rotating rod 3013 away from the bearing 3014. This arrangement ensures that when the servo motor 201 operates in the reverse direction, the second guide plate 3015 can be reset. Therefore, the reset of the second guide plate 3015 can push the energy-saving sheet metal body 102, so that the energy-saving sheet metal body 102 can be guided by the second guide plate 3015 and can be transported in a straight line on the conveyor body 101, thereby ensuring that collision with the baffle 1011 is avoided to a certain extent during transportation on the conveyor body 101.

[0031] The implementation principle of the energy-saving sheet metal roller segmented buffer device of the present invention is as follows: First, the staff places the energy-saving sheet metal plate body 102 on the conveyor body 101. When the energy-saving sheet metal plate body 102 is placed, the staff starts the conveyor body 101 to transport the placed energy-saving sheet metal plate body 102. When the energy-saving sheet metal body 102 is transferred to a certain position (that is, when the energy-saving sheet metal body 102 touches the mounting plate 2012), the servo motor 201 can be operated, so that the servo motor 201 can drive the rotating rod 2011 to rotate. When the rotating rod 2011 rotates, the rotating rod 2011 can drive the mounting plate 2012 to rotate (when the mounting plate 2012 rotates, it can ensure that the mounting plate 2012 itself leaves the conveyor body 101); When the mounting plate 2012 rotates, it can pass through the rotating rod 202 disposed in the rectangular notch 2013, allowing the rotating rod 202 to follow the circular motion (because the rotating rod 202 is provided with a bearing seat 2022, and the bearing seat 2022 is provided with a mounting bracket 2023, thus ensuring that the rotating rod 202 will not fall); When the rotating rod 202 moves in a circle, it can drive the driving gear 205 to move in a circle. At the same time, because the driving gear 205 is meshed with a gear ring 2051, it can ensure that the driving gear 205 can also rotate when it moves in a circle. When the driving gear 205 rotates, it can drive the rotating rod 202 to rotate, so that the rotation of the rotating rod 202 can drive the first guide plate 2021 to rotate. Therefore, the rotation of the first guide plate 2021 can push the energy-saving sheet metal plate body 102, so that the trajectory of the energy-saving sheet metal plate body 102 can be changed when it is transmitted on the conveyor body 101 (wherein the speed of the roller on the conveyor body 101 is adjustable and slowed down, and its specific adjustable slowing down is the existing technology, thereby ensuring that when the energy-saving sheet metal plate body 102 is transmitted, the energy-saving sheet metal plate body 102 can play a buffering role); When the rotating rod 202 rotates, it can also drive the first pulley 301 to rotate. When the first pulley 301 rotates, it can drive the second pulley 3011 to rotate through the transmission belt 3012. When the second pulley 3011 rotates, it can drive the rotating rod 3013 to rotate. When the rotating rod 3013 rotates, it can drive the second guide plate 3015 to rotate, so that one end of the second guide plate 3015 can be close to the side of the baffle 1011. When the rotating rod 202 rotates, it can also drive the connecting rod 204 to rotate. When the connecting rod 204 rotates, it can push the connecting rod 2042 to move horizontally with the assistance of the moving slide groove 2043 and the moving slider 2044, thereby driving the arc-shaped limit plate 2041 to move, so that the energy-saving sheet metal plate body 102 transmitted on the conveyor body 101 can be blocked and limited by the arc-shaped limit plate 2041, thereby avoiding the energy-saving sheet metal plate body 102 and the baffle 1011 from colliding (because the inner cavity of the moving slide groove 2043 is provided with a return spring 2045, and the other end of the return spring 2045 is provided on the moving slider 2044, it is ensured that the moving slider 2044 can be reset, thereby driving the connecting rod 2042 to reset); When the energy-saving sheet metal plate body 102 has completed guiding on the first guide plate 2021 (that is, when the energy-saving sheet metal plate body 102 leaves the first guide plate 2021 as a whole), the servo motor 201 can run in reverse, thereby driving all of the above-mentioned resets. When the second guide plate 3015 is reset, it can push the energy-saving sheet metal plate body 102 through the reset of the second guide plate 3015, so that the energy-saving sheet metal plate body 102 can be guided by the second guide plate 3015, and thus can be transmitted in a straight line on the conveyor body 101, thereby ensuring that when being transmitted on the conveyor body 101, collision with the baffle 1011 is avoided to a certain extent.
