Abstract
Description
Technical Field
[0001] This application relates to the field of tobacco leaf impurity removal technology, and in particular to a chain-type baffle device applied to a photoelectric impurity removal machine. Background Technology
[0002] In the process of removing impurities from tobacco, the photoelectric impurity remover is the core equipment for removing foreign objects. It separates impurities in tobacco leaves through optical recognition and high-speed actuators. After being removed by the photoelectric impurity remover, the tobacco leaves are sent into an ultra-light and ultra-fine impurity sorting box by a conveyor belt mechanism and a fan. The sorting box is equipped with a baffle device, which is usually used to control the flow path of the tobacco leaves and assist in the separation of impurities.
[0003] However, existing material blocking devices are generally set as perforated arc plates or smooth plates. If the material blocking device is a perforated arc plate, but the material blocking device is a smooth plate structure, the tobacco leaves will generate airflow swirling when they pass through the smooth plate at high speed, returning to the conveyor belt mechanism, resulting in a reduction in impurity removal efficiency. Utility Model Content
[0004] To further improve the impurity removal efficiency of the impurity removal machine, this application provides a chain-type material blocking device for use in a photoelectric impurity removal machine.
[0005] The chain-type material blocking device for use in a photoelectric impermeable machine provided in this application adopts the following technical solution:
[0006] A chain-type baffle device for use in a photoelectric impurity removal machine includes a bracket and a chain-shaped baffle cover. The bracket is installed on the inner side wall of the sorting box, and the chain-shaped baffle cover is installed on the bracket and hangs down naturally under the influence of gravity. The chain-shaped baffle cover includes a mounting rod and multiple sets of chains. The mounting rod is installed on the bracket, and the multiple sets of chains are arranged sequentially along the length of the mounting rod. The bracket is provided with an opening for heavy impurities to pass through.
[0007] By adopting the above technical solution, when feeding tobacco leaves by using a chain baffle, the airflow generated after the tobacco leaves hit the baffle can pass through the baffle, thereby avoiding the problem of airflow swirling and improving the impurity removal efficiency. At the same time, the opening above the support can allow heavy impurities to pass through, realizing the separation of impurities.
[0008] In one specific implementation, the bracket has limit grooves on both sides, and the mounting rod has limit rods installed at both ends, with the limit rods slidably connected in the limit grooves on both sides.
[0009] By adopting the above technical solution, limiting grooves are opened on both sides of the bracket, and fiber slide rods are installed at both ends of the mounting rod and slidably connected in the limiting grooves, so that the mounting rod can slide stably, thereby allowing the position of the baffle to be adjusted at will for better material blocking.
[0010] In one specific implementation, the chain is composed of multiple links connected in sequence.
[0011] By adopting the above technical solution, since the chain is vertical and composed of multiple chain links linked in sequence, there are no sharp edges, which can reduce the possibility of tobacco leaf breakage when it impacts the baffle at high speed.
[0012] In one specific implementation, a hinge is installed on one side of the bracket, and the bracket is hinged to the side wall of the box via the hinge. An adjustment component is installed on the top of the box, and the adjustment component is connected to the other side of the bracket to drive the bracket to rotate relative to the side wall of the box.
[0013] By adopting the above technical solution, the bracket is hinged to the side wall of the box through a hinge, and the adjusting component is connected to the other side of the bracket, which can drive the bracket to rotate relative to the side wall of the box. The bracket angle can be flexibly adjusted according to actual use needs, thereby adjusting the position of the chain baffle, so that the baffle device can better adapt to different working conditions and improve the impurity removal effect and applicability.
[0014] In one specific implementation scheme, the adjusting component includes an adjusting motor, an adjusting lead screw, a slider, and a hydraulic rod. A mounting groove is provided on the upper side wall of the housing. The adjusting motor is mounted on the housing. The adjusting lead screw is connected to the output shaft of the adjusting motor and is mounted in the mounting groove. The slider is slidably connected in the mounting groove and is drivenly connected to the adjusting lead screw. The piston rod of the adjusting cylinder is connected to the slider. One end of the hydraulic rod is mounted on the slider, and the other end is hinged to the end of the bracket away from the side wall of the housing.
[0015] By adopting the above technical solution, the adjusting motor drives the adjusting screw to rotate, thereby causing the slider to slide along the mounting groove. Then, the hydraulic rod contracts to drive the bracket to rotate relative to the hinge, thereby causing the bracket to flip upward. This avoids interference with the bracket when the staff cleans the box.
[0016] In one specific implementation, two hydraulic rods are provided, which are respectively installed on both sides of the slider in the length direction. The slider in the length direction is parallel to the support in the length direction, and the ends of the hydraulic rods away from the slider are hinged to the two sides of the support in the length direction.
[0017] By adopting the above technical solution, the hydraulic rod is hinged to both sides of the support along the length of the slider, which allows the adjusting component to drive the support to rotate relative to the side wall of the box more stably, thereby improving the operational stability of the device.
[0018] In one specific implementation, the bracket includes a support plate and a support rod, and a plurality of support plates and support rods are provided. The support rods are disposed through a plurality of support plates and are arranged sequentially along the length direction of the support plates. The hinge is installed on the support rod located at one edge of the support plate.
[0019] By adopting the above technical solution, the hinge is installed on the support rod located at one edge of the support plate, which facilitates the hinge of the bracket to the side wall of the box, allowing the bracket to rotate relative to the side wall of the box, thereby flexibly adjusting the angle of the chain baffle device, improving the control of the tobacco leaf flow path and the impurity separation effect.
[0020] In one specific implementation, the support rods are installed sequentially along the length of the support plate, and an opening is formed between adjacent support rods for heavy debris to pass through.
[0021] By adopting the above technical solution, the support rods are installed sequentially along the length of the support plate, forming an opening between adjacent support rods, which allows heavy debris to pass through smoothly, further ensuring the smoothness of the impurity removal process and improving the impurity removal effect.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The chain baffle can prevent the tobacco leaves from swirling back onto the conveyor belt when they hit the conveyor belt at high speed, thereby improving the impurity removal efficiency.
[0024] 2. The support is equipped with openings for heavy debris to pass through, which helps the heavy debris to pass through smoothly and thus achieves the effect of assisting in the separation of impurities. Attached Figure Description

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0029] This application discloses a chain-type material blocking device applied to a photoelectric cleaning machine.
[0030] like Figure 1 and Figure 2 As shown, the chain-type baffle device applied to the photoelectric impurity remover includes a support 1 and a chain-shaped baffle 2. The support 1 is installed on one side wall of the sorting box, and a feed inlet is opened on this side wall of the air classifier. The air classifier is connected to the photoelectric impurity remover. The photoelectric impurity remover feeds material into the feed inlet through a conveyor belt mechanism and a fan. The conveyor belt mechanism is set at an angle upward, which can throw tobacco leaves and heavy impurities at an angle upward toward the chain-shaped baffle 2. The chain-shaped baffle 2 is installed on the support 1 and hangs down naturally under the influence of gravity. Above the support 1 An opening is provided for heavy debris to pass through. The tobacco leaves are blown towards the chain baffle 2 by the conveyor belt mechanism and the fan and impact the chain baffle 2. Since the chain baffle 2 has multiple gaps, the airflow will break through the surface, thus avoiding airflow swirl. At the same time, since the heavy debris has a large mass and a small volume, it experiences less air resistance. Under the action of the fan and the conveyor belt mechanism, it passes through the opening above the support 1 and over the chain baffle 2 with a higher arc, thereby achieving the separation of impurities from tobacco leaves.
[0031] The chain-shaped material stop 2 includes a mounting rod 21 and multiple sets of chains 22. The mounting rod 21 is used to fix the chains 22, allowing them to be arranged in an orderly manner. The mounting rod 21 can be made of metal, possessing a certain strength and rigidity, and can provide good support for the chains 22. The multiple sets of chains 22 are arranged sequentially along the length of the mounting rod 21. Each chain 22 is composed of multiple links connected sequentially. The links are usually made of metal, possessing good wear resistance and corrosion resistance. At the same time, the chains 22 have good flexibility, allowing them to hang naturally and swing flexibly when impacted, reducing obstruction to airflow. The chains 22 are spaced apart, serving both as a material stop and allowing airflow to pass through.
[0032] The support frame 1 includes support plates 11 and support rods 12, with multiple support plates 11 and support rods 12. The support plates 11 can be flat, made of metal or rigid plastic. Support rods 12 pass through multiple support plates 11, arranged sequentially along the length of the support plates 11. This structure provides the support frame 1 with good stability and strength, allowing it to be firmly installed on the inner wall of the sorting box. The support rods 12 are installed sequentially along the length of the support plates 11, forming openings between adjacent support rods 12 for heavy debris to pass through. This allows heavy debris to fall through these openings, preventing it from accumulating on the support frame 1 and affecting the debris removal effect.
[0033] Limiting grooves 13 are provided on both side support plates 11, and limiting rods 23 are correspondingly installed at both ends of the mounting rod 21. The limiting rods 23 are slidably connected in the limiting grooves 13 on both sides. The limiting grooves 13 can be grooves formed on the side of the bracket 1, and their shape can be rectangular or trapezoidal. The limiting rods 23 can be cylindrical rods, and their material is similar to that of the mounting rod 21. By sliding the limiting rods 23 in the limiting grooves 13, the mounting rod 21 can be limited, ensuring the stability of the chain-like baffle 2 installation, and also facilitating the installation and removal of the chain-like baffle 2.
[0034] A hinge 3 is installed on one side of the bracket 1, and the bracket 1 is hinged to the side wall of the housing via the hinge 3. An adjusting component 4 is installed on the top of the housing, and the adjusting component 4 is connected to the other side of the bracket 1 to drive the bracket 1 to rotate relative to the side wall of the housing. The hinge 3 can be a hinge, which is usually made of metal, and allows the bracket 1 to rotate flexibly. The adjusting component 4 includes an adjusting motor 41, an adjusting screw 42, a slider 43, and a hydraulic rod 44. A mounting groove is opened on the upper side wall of the housing. The adjusting motor 41 is mounted on the side wall of the housing. The adjusting screw 42 is fixedly connected to the output shaft of the adjusting motor 41 and is installed in the mounting groove. The slider 43 is slidably connected in the mounting groove and is driven by the adjusting screw 42. One end of the hydraulic rod 44 is mounted on the slider 43, and the other end is hinged to the end of the bracket 1 away from the side wall of the housing. When the adjusting cylinder is working, it can push the slider 43 to slide on the upper side wall of the housing, thereby driving the bracket 1 to rotate relative to the side wall of the housing through the hydraulic rod 44. By adjusting the angle of the bracket 1, the tilt of the chain baffle 2 can be adjusted to adapt to different impurity removal conditions.
[0035] There are two pressure rods, with two hydraulic rods 44 installed on both sides of the slider 43 along its length. The slider 43 is parallel to the length of the bracket 1, and the ends of the hydraulic rods 44 facing away from the slider 43 are hinged to the sides of the bracket 1 along its length. This arrangement allows the bracket 1 to be subjected to more even force, ensuring the stability and reliability of the bracket 1's rotation.
[0036] The implementation principle of a chain-type baffle device applied to a photoelectric impurity removal machine according to an embodiment of this application is as follows: This embodiment uses a chain-shaped baffle 2 that hangs naturally downwards, effectively avoiding airflow swirl as seen in existing bare plate baffle devices, thus improving impurity removal efficiency. The flexibility of the chain 22 allows it to swing flexibly when impacted by tobacco leaves, reducing obstruction to airflow. The opening on the support 1 facilitates the falling of heavy impurities, preventing accumulation that could affect impurity removal. The limiting slide groove 13 and limiting slide rod 23 ensure stable installation of the chain-shaped baffle 2. The adjusting component 4 can drive the support 1 to rotate, adjusting the tilt angle of the chain-shaped baffle 2 to adapt to different working conditions, representing a significant improvement and enhancement compared to existing technologies.
[0037] 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.
