Description

Technical Field

[0001] This application relates to the technical field of toner raw material transportation, and particularly to a transportation device for toner raw materials. Background Art

[0002] Toner, also known as carbon powder, is a powdery substance that forms an image and is fixed on paper in a laser printer. Toner is composed of raw materials such as resin, carbon black, charge control agent, and external additives. During the toner manufacturing process, it is necessary to mix the above-mentioned various powdery or granular raw materials to form a toner finished product through subsequent processing.

[0003] The toner raw materials are separately stored in different storage bins. When mixing, different raw materials need to be put into a mixing container. Currently, the commonly used methods include manual pouring and mechanical transportation; among them, manual pouring is to manually put the raw materials in the storage bin into the mixing container; mechanical transportation generally uses screw transportation, relying on the rotation of the screw blade to push the raw materials to move.

[0004] However, during manual pouring, a large amount of dust is easily generated in the process of transporting the toner raw materials, which affects the safety and hygiene of the working environment; while screw transportation, due to the rotation of the screw blade to push the raw materials, it is easy to cause the problem that the raw materials remaining inside the mechanical structure are not easy to clean, which not only causes waste but also leads to the risk of cross-contamination when replacing different types of toner raw materials subsequently, affecting the product quality.

[0005] In the above related technologies, there are defects that the transportation of toner raw materials is prone to cause dust pollution and the transportation structure is not easy to clean. Summary of the Invention

[0006] In order to improve the problems that the transportation of toner raw materials is prone to cause dust pollution and the transportation structure is not easy to clean, this application provides a transportation device for toner raw materials.

[0007] The transportation device for toner raw materials provided by this application adopts the following technical solutions: A conveying device for toner raw materials, comprising: a support mechanism; a cylinder body, the cylinder body is mounted on the support mechanism, and an accommodation cavity, a filtering cavity and a driving cavity are arranged in the cylinder body, the accommodation cavity is arranged below the filtering cavity, and the driving cavity is arranged above the filtering cavity; a feeding mechanism, the first end of the feeding mechanism communicates with the accommodation cavity, and the second end of the feeding mechanism can extend into a storage bin, and the storage bin is used for carrying toner raw materials; a first filtering mechanism, arranged in the filtering cavity, and the gas in the accommodation cavity can flow to the driving cavity after being filtered by the first filtering mechanism; a driving mechanism, the driving mechanism includes a driving member, a connecting component and a sliding plate, the driving member is arranged on the support mechanism, the driving member is arranged on one side of the cylinder body, the first end of the connecting component is connected to the driving member, the second end of the connecting component communicates with the driving cavity, the driving member can suck air from the driving cavity, so that the air pressure in the driving cavity and the accommodation cavity is reduced, so that the toner raw materials in the storage bin are sucked into the accommodation cavity, the sliding plate is slidably connected to the inner wall of the driving cavity, and the sliding plate can move in a direction close to or away from the first filtering mechanism along with the change of the air pressure in the driving cavity, the second end of the connecting component is flush with the inner wall of the driving cavity, and the side wall of the sliding plate is slidably matched with the second end of the connecting component for scraping the second end of the connecting component.

[0008] By adopting the above technical solutions, the support mechanism provides a supporting effect for the cylinder body and the driving member. The driving member communicates with the driving cavity of the cylinder body through the connecting component. Since the driving cavity communicates with the accommodation cavity through the filtering cavity, the driving cavity can be evacuated by the driving member, so that a negative pressure environment is formed in the accommodation cavity. Furthermore, through the feeding mechanism connected to the accommodation cavity, the powdery toner raw materials in the storage bin can be sucked into the accommodation cavity; a first filtering mechanism is arranged in the filtering cavity, which can filter the gas flowing from the accommodation cavity to the driving cavity during the air suction process, reduce the possibility of raw materials entering the driving cavity, reduce the cleaning difficulty of the driving cavity, and at the same time, reduce the risk of raw materials and dust entering the driving member, improving the reliability of the driving member; moreover, a sliding plate is arranged in the driving cavity, so that the sliding plate slides along the inner wall of the driving cavity under the change of the internal air pressure of the driving cavity, thereby realizing the scraping of the driving cavity and simultaneously scraping the second end of the connecting component extending into the driving cavity, further optimizing the cleaning effect of the driving cavity, further reducing the cleaning difficulty, simplifying the operation process, and improving the automation degree and working efficiency; the conveying of raw materials is realized in the form of pneumatic suction by a mechanical structure. Compared with manual dumping, it can reduce the labor intensity and reduce the safety hazard of dust flying to the operator; at the same time, pneumatic negative pressure conveying can reduce the adhesion of raw material dust to the mechanical structure during the conveying process and reduce the cleaning difficulty.

[0009] Optionally, the second end of the connection component includes a first interface and a second interface. The first interface is provided on the side wall of the driving cavity, and the sliding plate is slidably engaged with the first interface. The second interface is provided at the top of the driving cavity, and the second interface is used to create a negative pressure above the sliding plate to move the sliding plate upward.

[0010] By adopting the above technical solution, the first interface is used to evacuate the driving cavity to create a negative pressure environment in the accommodating cavity, so as to suck the toner raw material through the feeding mechanism; the second interface is provided above the sliding plate to create a negative pressure environment above the sliding plate, thereby driving the sliding plate to move upward; since the lower part of the sliding plate is connected to the outside through the feeding mechanism, the pressure below the sliding plate is slightly less than the pressure above the sliding plate, so that the sliding plate can move upward under the suction of the second interface; during the upward movement of the sliding plate, the movement of the sliding plate in the driving cavity can play a piston role to optimize the suction effect below the sliding plate; since the first interface is provided on the side wall of the driving cavity and is slidably engaged with the sliding plate, when the suction stops, the sliding plate moves downward to scrape the first interface, reducing the risk of blockage of the first interface.

[0011] Optionally, it further includes a vibration mechanism. The vibration mechanism includes a telescopic member, a connecting shaft, a fan member, a ratchet and a pawl. A relief groove is provided on the side wall of the driving cavity. The telescopic member is provided in the relief groove and horizontally expands and contracts to selectively engage with the sliding plate so that the sliding plate can be arranged close to the top of the cylinder. The first end of the connecting shaft is rotatably connected to the lower side of the sliding plate, the second end of the connecting shaft is connected to the fan member, the ratchet is sleeved on the outer periphery of the connecting shaft, the first end of the pawl is rotatably connected to the sliding plate, and the second end of the pawl cooperates with the ratchet. The driving member can blow air into the driving cavity. The connecting shaft is offset and arranged on the lower side of the sliding plate so that the first interface can blow the fan member. The fan member drives the ratchet to rotate through the connecting shaft, so that the pawl and the ratchet move relative to each other.

[0012] By adopting the above technical solution, the telescopic member is provided in the relief groove on the side wall of the driving cavity and can horizontally expand and contract to selectively engage with the sliding plate, so that the sliding plate can be stably arranged close to the top of the cylinder. On this basis, when the driving member blows air into the driving cavity, the first interface can blow the fan member to rotate, and then drive the ratchet to rotate through the connecting shaft, realizing the relative movement of the pawl and the ratchet, thereby generating periodic mechanical vibration inside the driving cavity, which helps the raw materials and dust adhering to the inner wall of the cylinder to fall or the adhesiveness to decrease, thus facilitating the cleaning of the inside of the cylinder and reducing the cleaning difficulty.

[0013] Optionally, the cylinder body is provided with a limiting block, which is arranged above the first filtering mechanism and is used for clamping the sliding plate. The vertical distance between the limiting block and the first filtering mechanism is greater than the maximum vertical height between the fan member and the sliding plate.

[0014] By adopting the above technical solution, the setting of the limiting block can reduce the risk of interference between the vibration mechanism and the first filtering mechanism when the sliding plate moves downward, and improve the stability and reliability of the device operation.

[0015] Optionally, it further includes a control mechanism, which includes an operating platform and a detecting member. An elastic part is provided at the top of the cylinder body, and a convex block is provided on the upper side of the sliding plate. The convex block is arranged corresponding to the elastic part. When the sliding plate moves upward, the convex block drives the elastic part to be ejected. The detecting member is arranged at the top of the cylinder body and is used for detecting the protrusion of the elastic part. The operating platform is electrically connected to the driving member and is used for controlling the start and stop of the driving member. When the driving member is in the starting state, if the elastic part returns to its original position after protruding for more than a preset time, the operating platform controls the driving member to stop.

[0016] By adopting the above technical solution, the setting of the control mechanism enables the start and stop of the driving member to be automatically controlled according to the position of the sliding plate. When the sliding plate moves upward, the convex block drives the elastic part to be ejected. After the detecting member detects the protrusion of the elastic part, the operating platform controls the driving member to continue running. When the driving member runs continuously and the elastic part protrudes and then returns to its original position for more than a preset time, it indicates that the suction force below the sliding plate increases, and there is a blockage or full bin situation in the accommodating cavity. At this time, the operating platform can control the driving member to stop working, thereby effectively reducing the problem of excessive toner raw materials entering the accommodating cavity and facilitating obtaining the raw material carrying capacity situation in the accommodating cavity.

[0017] Optionally, the first filtering mechanism includes a connecting frame, a sealing strip and a first filter element. The filtering cavity is provided with a connecting part. The connecting frame is slidably connected to the connecting part. The sealing strip is coated on the end of the connecting frame and is used for cooperating with the connecting part for sealing. The first filter element is arranged in the connecting frame.

[0018] By adopting the above technical solution, the connecting frame is used to carry the first filter element. The connecting frame is slidably connected to the connecting part, which can facilitate the disassembly of the first filter element. Thus, by means of detachable connection, the cleaning and disassembly difficulty of the first filter element can be reduced to ensure the filtering effect. The sealing strip is coated on the end of the connecting frame and cooperates with the connecting part for sealing, keeping the inside of the cylinder body in a relatively sealed environment, which helps to realize the negative pressure suction function.

[0019] Optionally, the supporting mechanism includes a supporting plate and a plurality of rollers. The rollers are arranged below the supporting plate, and the cylinder body and the driving member are both arranged on the supporting plate.

[0020] By adopting the above technical solution, the support plate is used to carry the cylinder body and the driving member, and the rollers arranged below the support plate enable the device to move conveniently, so as to facilitate flexible adjustment of the position between different working positions, improve the mobility and flexibility of the device, contribute to improving work efficiency, and reduce the operation difficulty.

[0021] Optionally, the support mechanism includes a lifting assembly, and the lifting assembly includes a motor, a lead screw, a nut, a guide rod and a support member. The motor is arranged on the support plate, the output end of the motor is drivingly connected to the lead screw, the nut is screwed on the lead screw, the guide rod is arranged on one side of the lead screw, the guide rod is parallel to the lead screw, the nut is slidably connected to the guide rod, the first end of the support member is connected to the lead screw and the guide rod, the second end of the support member is connected to the support plate, and the nut is connected to the cylinder body, so that the cylinder body can move vertically.

[0022] By adopting the above technical solution, the motor of the lifting assembly drives the lead screw to rotate, thereby driving the nut to move up and down along the guide rod, and further realizing the vertical movement of the cylinder body, facilitating the adjustment of the height of the cylinder body according to different working conditions, and improving the adaptability and operation convenience of the device.

[0023] Optionally, it further includes a second filtering mechanism. The first end of the second filtering mechanism is connected to the output end of the driving member, and the second end of the second filtering mechanism is connected to the connecting assembly. The second filtering mechanism is used for filtering the gas entering the driving member.

[0024] By adopting the above technical solution, the second filtering mechanism can effectively filter the gas entering the driving member, avoid impurities from entering the inside of the driving member and causing damage to the driving member, and improve the working stability and service life of the driving member.

[0025] Optionally, a flexible suction cup is arranged on the outer periphery of the second interface, and the flexible suction cup is used for adsorbing the sliding plate.

[0026] By adopting the above technical solution, the flexible suction cup on the outer periphery of the second interface can effectively adsorb the sliding plate, improve the reliability of the connection between the sliding plate and the second interface, enable the sliding plate to be stably connected to the second interface and the flexible suction cup during the raw material suction process, improve the reliability of the device, and reduce the risk that the sliding plate moves downward accidentally and affects the suction effect.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The support mechanism provides support for the cylinder body and the driving member. The driving member is connected to the driving cavity of the cylinder body through the connecting component. Since the driving cavity is connected to the accommodating cavity through the filtering cavity, the driving cavity can be evacuated by the driving member, creating a negative pressure environment in the accommodating cavity. Then, through the feeding mechanism connected to the accommodating cavity, the powdery toner raw material in the storage tank can be sucked into the accommodating cavity. A first filtering mechanism is provided in the filtering cavity, which can filter the gas flowing from the accommodating cavity to the driving cavity during the suction process, reducing the possibility of raw materials entering the driving cavity, lowering the cleaning difficulty of the driving cavity, and also reducing the risk of raw materials and dust entering the driving member, improving the reliability of the driving member. Moreover, a sliding plate is arranged in the driving cavity, and the sliding plate slides along the inner wall of the driving cavity under the change of the internal air pressure of the driving cavity, so as to realize the scraping of the driving cavity, and at the same time, scrape the second end of the connecting component extending into the driving cavity, further optimizing the cleaning effect of the driving cavity, further reducing the cleaning difficulty, simplifying the operation process, and improving the automation degree and working efficiency. The transportation of raw materials is realized in the form of mechanical structure pneumatic suction. Compared with manual dumping, it can reduce the labor intensity and the safety hazards of dust flying to the operators. At the same time, pneumatic negative pressure transportation can reduce the adhesion of raw material dust to the mechanical structure during transportation, reducing the cleaning difficulty. 2. The first interface is used to evacuate the driving cavity, creating a negative pressure environment in the accommodating cavity, so as to realize the suction of the toner raw material through the feeding mechanism. The second interface is arranged above the sliding plate, creating a negative pressure environment above the sliding plate, thus driving the sliding plate to move upward. Since the lower part of the sliding plate is connected to the outside through the feeding mechanism, the pressure below the sliding plate is slightly less than the pressure above the sliding plate, enabling the sliding plate to move upward under the suction of the second interface. During the upward movement of the sliding plate, the movement of the sliding plate in the driving cavity can play the role of a piston, optimizing the suction effect below the sliding plate. Since the first interface is arranged on the side wall of the driving cavity and is in sliding fit with the sliding plate, when stopping suction and other situations occur, the sliding plate moves downward to scrape the first interface, reducing the risk of blockage of the first interface. 3. The telescopic member is arranged in the avoidance groove on the side wall of the driving cavity and can be horizontally telescoped to selectively engage with the sliding plate, enabling the sliding plate to be stably arranged near the top of the cylinder body. On this basis, when the driving member blows air into the driving cavity, the first interface can blow the fan member to rotate, and then drive the ratchet to rotate through the connecting shaft, realizing the relative movement between the pawl and the ratchet, thereby generating periodic mechanical vibration inside the driving cavity, which helps the raw materials and dust adhering to the inner wall of the cylinder body to fall or the adhesion to decrease, facilitating the cleaning of the inside of the cylinder body and reducing the cleaning difficulty.

Moreover, in the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to this application. Without contrary description, the orientation words such as "inside" and "outside" used in this application refer to the contour of the corresponding component itself.

[0037] As Figure 1 , Figure 2 and Figure 3 shown, an embodiment of this application discloses a conveying device for toner raw materials (hereinafter simply referred to as "device"). The device includes a support mechanism 1, a cylinder body 2, a feeding mechanism 3, a first filtering mechanism 4, and a driving mechanism 5, and is used to suck the toner raw materials into the cylinder body 2 so as to convey the toner raw materials to the next working station subsequently.

[0038] As Figure 1 , Figure 2 and Figure 4 shown, the cylinder body 2 is mounted on the support mechanism 1. An accommodation cavity 21, a filtering cavity 22, and a driving cavity 23 are provided inside the cylinder body 2. The accommodation cavity 21 is arranged below the filtering cavity 22, and the driving cavity 23 is arranged above the filtering cavity 22. The first end of the feeding mechanism 3 communicates with the accommodation cavity 21, and the second end of the feeding mechanism 3 can extend into a storage box 9 which is used to carry the toner raw materials. The feeding mechanism 3 may include a feeding pipe. One end of the feeding pipe communicates with a position on one side of the accommodation cavity 21 close to the filtering cavity 22, and the other end of the feeding pipe extends into the storage box 9. The feeding mechanism 3 may further include necessary connection structures and support structures to enable the feeding pipe to be stably connected between the accommodation cavity 21 and the storage box 9. The first filtering mechanism 4 is arranged inside the filtering cavity 22, and the gas in the accommodation cavity 21 can flow into the driving cavity 23 after being filtered by the first filtering mechanism 4.

[0039] As Figure 1 , Figure 4 and Figure 5As shown in the figure, the driving mechanism 5 includes a driving member 51, a connecting component, and a sliding plate 53. The driving member 51 is arranged on the supporting mechanism 1, and the driving member 51 is arranged on one side of the cylinder body 2. The first end of the connecting component is connected to the driving member 51, and the second end of the connecting component communicates with the driving cavity 23. The driving member 51 can suck air from the driving cavity 23, reducing the air pressure in the driving cavity 23 and the accommodating cavity 21, so that the toner raw material in the storage tank 9 is sucked into the accommodating cavity 21. The sliding plate 53 is slidably connected to the inner wall of the driving cavity 23, and the sliding plate 53 can move in a direction closer to or farther from the first filtering mechanism 4 along with the change of the air pressure in the driving cavity 23. The second end of the connecting component is flush with the inner wall of the driving cavity 23, and the side wall of the sliding plate 53 is slidably matched with the second end of the connecting component, which is used to scrape the second end of the connecting component to reduce the accumulation of dust at the second end. The supporting mechanism 1 provides support for the cylinder body 2 and the driving member 51. The driving member 51 communicates with the driving cavity 23 of the cylinder body 2 through the connecting component. Since the driving cavity 23 communicates with the accommodating cavity 21 through the filtering cavity 22, the driving cavity 23 can be evacuated by the driving member 51, creating a negative pressure environment in the accommodating cavity 21. Then, through the feeding mechanism 3 connected to the accommodating cavity 21, the granular toner raw material in the storage tank 9 can be sucked into the accommodating cavity 21. A first filtering mechanism 4 is arranged in the filtering cavity 22, which can filter the gas flowing from the accommodating cavity 21 to the driving cavity 23 during the air suction process, reducing the possibility of toner raw material entering the driving cavity 23. While reducing the cleaning difficulty of the driving cavity 23, it can also reduce the risk of raw materials and dust entering the driving member 51, improving the reliability of the driving member 51. Moreover, a sliding plate 53 is arranged in the driving cavity 23, so that the sliding plate 53 slides along the inner wall of the driving cavity 23 under the change of the internal air pressure of the driving cavity 23, thereby realizing the scraping and cleaning of the driving cavity 23. At the same time, it also scrapes the second end of the connecting component extending into the driving cavity 23, which can optimize the cleaning effect of the driving cavity 23, further reduce the cleaning difficulty, simplify the operation process, and improve the automation degree and working efficiency of the whole device.

[0040] The device realizes the transportation of toner raw materials in the form of pneumatic suction by mechanical structure. Compared with manual pouring, it can reduce the labor intensity and the potential safety hazard of dust flying to the operator. At the same time, pneumatic negative pressure transportation can reduce the adhesion of raw material dust to the mechanical structure during transportation and reduce the cleaning difficulty. While adopting pneumatic transportation to reduce the cleaning difficulty, the physical movement of the sliding plate 53 can improve the cleaning effect of the driving cavity 23 and reduce the cleaning difficulty.

[0041] As Figure 1 、 Figure 4 and Figure 5As shown, optionally, the support mechanism 1 includes a support plate 11 and a plurality of rollers 12. The rollers 12 are arranged below the support plate 11, and both the cylinder body 2 and the driving member 51 are arranged on the support plate 11. The support plate 11 is used to carry the cylinder body 2 and the driving member 51, and the rollers 12 arranged below the support plate 11 enable the device to move conveniently, so as to facilitate flexible adjustment of the position between different working positions, improve the mobility and flexibility of the device, contribute to improving work efficiency, and reduce the operation difficulty.

[0042] Optionally, the support mechanism 1 includes a lifting assembly 13. The lifting assembly 13 includes a motor 131, a lead screw 132, a lead nut 133, a guide rod 134 and a support member 135. The motor 131 is arranged on the support plate 11, the output end of the motor 131 is drivingly connected to the lead screw 132, and the lead nut 133 is screwed onto the lead screw 132. The guide rod 134 is arranged on one side of the lead screw 132, the guide rod 134 is parallel to the lead screw 132, and the lead nut 133 is slidably connected to the guide rod 134. The first end of the support member 135 is connected to the lead screw 132 and the guide rod 134, the lead screw 132 is rotatably connected to the support member 135, and the second end of the support member 135 is connected to the support plate 11 to realize the supporting effect on the lead screw 132 and the guide rod 134. The lead nut 133 is connected to the cylinder body 2, so that the cylinder body 2 can move vertically. The motor 131 of the lifting assembly 13 drives the lead screw 132 to rotate, thereby driving the lead nut 133 to move up and down along the guide rod 134, and further realizing the vertical movement of the cylinder body 2, which is convenient for adjusting the height of the cylinder body 2 according to different working conditions, and improving the adaptability and operation convenience of the device.

[0043] As Figure 1 、 Figure 4 and Figure 5 shown, optionally, the first filtering mechanism 4 includes a connecting frame 41, a sealing strip and a first filter element 42, and the filtering cavity 22 is provided with a connecting portion. The connecting frame 41 is slidably connected to the connecting portion, and the first filter element 42 is arranged in the connecting frame 41. The connecting frame 41 is used to carry the first filter element 42, and the slidable connection between the connecting frame 41 and the connecting portion can facilitate the disassembly and replacement of the first filter element 42. Thus, in a detachable connection manner, the cleaning and disassembly difficulty of the first filter element 42 is reduced to ensure the filtering effect. The sealing strip is coated on the end of the connecting frame 41, and the sealing strip is used to cooperate with the connecting portion for sealing. After the first filtering mechanism 4 is inserted into the connecting portion, a relatively sealed environment is maintained inside the cylinder body 2, which helps to realize the negative pressure suction function; the sealing strip can select an existing sealing strip structure according to needs, and its installation position can also be adjusted according to needs, as long as a reliable sealing effect can be achieved. The connecting portion is a groove-shaped structure so that the connecting frame 41 can be inserted. Locking structures can be arranged on both the connecting frame 41 and the cylinder body 2 to realize the locking of the connecting frame 41 and improve the installation reliability.

[0044] Optionally, the device further includes a second filtering mechanism 8. The first end of the second filtering mechanism 8 is connected to the output end of the driving member 51, the second end of the second filtering mechanism 8 is connected to the connecting component, and the second filtering mechanism 8 is used to filter the gas entering the driving member 51. The second filtering mechanism 8 can effectively filter the gas entering the driving member 51, prevent impurities from entering the driving member 51 and causing damage to the driving member 51, and improve the working stability and service life of the driving member 51. The second filtering mechanism 8 can be a cyclone separator or a material separator; the structures and installation methods of the first filter element 42 and the second filtering mechanism 8 can both adopt existing technologies as long as they can achieve a reliable filtering effect.

[0045] As Figure 1 , Figure 4 and Figure 5 shown, optionally, the second end of the connecting component includes a first interface 521 and a second interface 522. The first interface 521 is provided on the side wall of the driving cavity 23, and the sliding plate 53 is slidably matched with the first interface 521. The first interface 521 is used to evacuate the driving cavity 23 to form a negative pressure environment in the accommodating cavity 21, so as to suck the toner raw material through the feeding mechanism 3. The second interface 522 is provided on the top of the driving cavity 23, and the second interface 522 is used to form a negative pressure above the sliding plate 53 to move the sliding plate 53 upward. Since the lower part of the sliding plate 53 is connected to the outside through the feeding mechanism 3, the pressure below the sliding plate 53 is slightly less than the pressure above the sliding plate 53, so that the sliding plate 53 can move upward under the suction of the second interface 522. During the upward movement of the sliding plate 53, the sliding plate 53 can act as a piston through its movement in the driving cavity 23 to optimize the suction effect below the sliding plate 53. Since the first interface 521 is provided on the side wall of the driving cavity 23 and is slidably matched with the sliding plate 53, when the suction stops, the sliding plate 53 can move downward to scrape the first interface 521, reducing the risk of blockage of the first interface 521.

[0046] As Figure 1 , Figure 4 and Figure 5As shown, optionally, the connecting component includes a first pipeline 525 and a second pipeline 526. The first pipeline 525 and the second pipeline 526 are in parallel. Two ends of the first pipeline 525 are respectively connected to a driving member 51 and a first interface 521, and two ends of the second pipeline 526 are respectively connected to the driving member 51 and a second interface 522. By setting the lengths and diameters of the first pipeline 525 and the second pipeline 526, the pressures at the first interface 521 and the second interface 522 can be adjusted to be the same or meet the usage requirements as needed, so that the sliding plate 53 can move in the driving cavity 23; specifically, in this embodiment, the thickness of the sliding plate 53 can be made smaller than the diameter of the first interface 521 to prevent the sliding plate 53 from blocking the first interface 521; further, a detachable pressure regulating valve can be provided on the second pipeline 526, and the direction of the pressure regulating valve can be adjusted according to the gas flow direction so that the pressure regulating valve can be applicable to both the inhalation and exhalation conditions; two pressure regulating valves with different directions can also be provided, and one of the pressure reducing valves can be selectively made to function through an electromagnetic valve. Necessary control valve bodies can be provided on both the first pipeline 525 and the second pipeline 526 to respectively control the opening and closing or the suction force of the first interface 521 and the second interface 522; a pressure relief valve can also be provided on the second pipeline 526 so that the sliding plate 53 can reliably move vertically. The first pipeline 525 and the second pipeline 526 are connected to a second filtering mechanism 8 through a main pipeline, and the main pipeline is detachably connected. On the one hand, it is convenient for replacement and cleaning, and on the other hand, a main pipeline with a suitable length can be selected according to the height of the cylinder body 2; the main pipeline can also be made telescopic to facilitate length adjustment; the connecting component is supported through a necessary supporting structure. Two driving members 51 can also be provided, and the two driving members 51 respectively correspond to the first pipeline 525 and the second pipeline 526 to achieve precise control of the gas flow rates in the first pipeline 525 and the second pipeline 526.

[0047] Optionally, a filter plate 524 is provided at the end of the first interface 521. The filter plate 524 is flush with the inner side wall of the driving cavity 23, and the sliding plate 53 is in sliding fit with the filter plate 524 for scraping the filter plate 524, so as to effectively remove impurities on the filter plate 524, ensure the smooth flow of gas, improve the filtering effect and the stability of the device. The filter plate 524 can adopt a frame structure with a HEPA high-efficiency filter net inside, which can filter out particulate matter with a diameter less than 0.3 microns to ensure the filtering effect.

[0048] As Figure 1 、 Figure 4 and Figure 5As shown, optionally, a flexible suction cup 523 is provided on the outer periphery of the second interface 522. The flexible suction cup 523 is used to adsorb the upper side of the sliding plate 53. The flexible suction cup 523 on the outer periphery of the second interface 522 can effectively adsorb the sliding plate 53, improve the reliability of the connection between the sliding plate 53 and the second interface 522, enable the sliding plate 53 to be stably connected to the second interface 522 and the flexible suction cup 523 during the raw material inhalation process, improve the reliability of the device, and reduce the risk that the accidental downward movement of the sliding plate 53 affects the inhalation effect.

[0049] As Figure 4 , Figure 5 and Figure 6 shown, optionally, the device further includes a vibration mechanism 6. The vibration mechanism 6 includes a telescopic member 61, a connecting shaft 62, a fan member 63, a ratchet 64 and a pawl 65. A horizontally extending avoidance groove is provided on the side wall of the driving cavity 23. The telescopic member 61 is arranged in the avoidance groove. The telescopic member 61 horizontally expands and contracts and is used to selectively engage with the sliding plate 53, so that the sliding plate 53 can be stably close to the top of the cylinder body 2 after moving upward. The first end of the connecting shaft 62 is rotatably connected to the lower side of the sliding plate 53. The second end of the connecting shaft 62 is connected to the fan member 63. The ratchet 64 is sleeved on the outer periphery of the connecting shaft 62. The first end of the pawl 65 is rotatably connected to the sliding plate 53. The second end of the pawl 65 cooperates with the ratchet 64. The pawl 65 is supported by a spring. One end of the spring away from the pawl 65 is fixedly connected to the sliding plate 53, so that the pawl 65 abuts against the ratchet 64. The driving member 51 can blow air into the driving cavity 23. The connecting shaft 62 is offset and arranged on the lower side of the sliding plate 53, so that the first interface 521 can blow the fan member 63. The fan member 63 drives the ratchet 64 to rotate through the connecting shaft 62, so that the pawl 65 and the ratchet 64 move relative to each other to generate vibration. Multiple avoidance grooves and telescopic members 61 can be provided to improve the load-bearing stability of the sliding plate 53; the telescopic member 61 can be a structure such as a cylinder, a hydraulic cylinder or an electric telescopic rod that can achieve the telescopic function.

[0050] The telescopic member 61 is disposed in the avoidance groove on the side wall of the driving cavity 23 and can be horizontally telescoped to selectively engage with the sliding plate 53. When it is necessary to clean the cylinder body 2, the sliding plate 53 can be stably arranged close to the top of the cylinder body 2. On this basis, when the driving member 51 blows air into the driving cavity 23, the first interface 521 can blow the fan member 63 to rotate, and then drive the ratchet wheel 64 to rotate through the connecting shaft 62, realizing the relative movement between the pawl 65 and the ratchet wheel 64, so as to generate periodic mechanical vibration inside the driving cavity 23, which helps the raw materials and dust adhering to the inner wall of the cylinder body 2 to fall or the adhesiveness to decrease, so as to facilitate the cleaning of the inside of the cylinder body 2 and reduce the cleaning difficulty. On the basis of the driving member 51 blowing air to clean the inside of the cylinder body 2, the vibration mechanism 6 generates vibration through the blowing of the first interface 521, so as to optimize the cleaning effect of the raw materials inside the cylinder body 2. A discharge port 25 is provided at the lower end of the accommodating cavity 21. The discharge port 25 is used to connect with the mixing device to conveniently and reliably convey the toner raw materials transported into the accommodating cavity 21 to the mixing device, reducing the labor intensity of the operators and at the same time reducing the dust pollution during the direct pouring process of the storage tank 9. A control valve can be provided at the discharge port 25 so as to selectively open or close the discharge port 25. Further, the accommodating cavity 21 can adopt a segmented structure to facilitate the disassembly and internal cleaning of the accommodating cavity 21. The driving member 51 can be a high-pressure blower or other blower structures that can realize blowing and suction. After the raw materials inside the accommodating cavity 21 are emptied, the driving member 51 stops sucking air; after the telescopic member 61 engages with the sliding plate 53, the driving member 51 blows air, and the first interface 521 blows the fan member 63, reducing the residue of the raw materials on the cylinder body 2 through vibration; then the telescopic member 61 retracts, and the sliding plate 53 moves downward to scrape the first interface 521 and the inner side wall of the driving cavity 23, further improving the cleaning effect. And, by disassembling the first filtering mechanism 4, it helps the raw materials inside the cylinder body 2 to be discharged through the discharge port 25.

[0051] As Figure 1 , Figure 4 and Figure 5 shown, optionally, the cylinder body 2 is provided with a limiting block 66. The limiting block 66 is disposed above the first filtering mechanism 4. The limiting block 66 is used to engage with the sliding plate 53. The vertical distance between the limiting block 66 and the first filtering mechanism 4 is greater than the maximum vertical height between the fan member 63 and the sliding plate 53. The setting of the limiting block 66 can reduce the risk of interference between the vibration mechanism 6 and the first filtering mechanism 4 when the sliding plate 53 moves downward, improving the stability and reliability of the device operation.

[0052] As Figure 1 , Figure 2 and Figure 4As shown, optionally, the device further includes a control mechanism 7, and the control mechanism 7 includes an operation console 71 and a detection member 72. An elastic portion 24 is provided at the top of the cylinder body 2, and a convex block 531 is provided on the upper side of the sliding plate 53. The convex block 531 is arranged corresponding to the elastic portion 24. When the sliding plate 53 moves upward, the convex block 531 drives the elastic portion 24 to be pushed out. The detection member 72 is arranged at the top of the cylinder body 2 and is used to detect the protrusion of the elastic portion 24. The operation console 71 is electrically connected to the driving member 51 and is used to control the start and stop of the driving member 51. When the driving member 51 maintains the start and suction state, if the elastic portion 24 returns to its original position after protruding for more than a preset time, the operation console 71 controls the driving member 51 to stop. The setting of the control mechanism 7 enables the start and stop of the driving member 51 to be automatically controlled according to the position of the sliding plate 53. When the sliding plate 53 moves upward, the convex block 531 drives the elastic portion 24 to be pushed out. After the detection member 72 detects the protrusion of the elastic portion 24, the operation console 71 controls the driving member 51 to continue running; when the driving member 51 continues to run and the elastic portion 24 returns to its original position after protruding for more than a preset time, it indicates that the suction force below the sliding plate 53 increases, and there is a blockage or full bin situation in the accommodation cavity 21. At this time, the operation console 71 can control the driving member 51 to stop working, thereby effectively reducing the problem of excessive toner raw materials entering the accommodation cavity 21 and facilitating obtaining the raw material carrying capacity situation in the accommodation cavity 21. It can be understood that the operation console 71 has necessary electrical connections with other structures of the device to achieve the purpose of controlling and operating on the operation console 71 and reducing the operation difficulty. The elastic portion 24 can be a rubber layer connected to a through hole provided at the top of the cylinder body 2; the detection member 72 can be a photoelectric sensor.

[0053] It can be understood that the device further includes necessary structures for functions such as connection, support, drive, positioning, limit, sealing, and control, so that the device can operate normally; parameters such as the shape, size, material, and set quantity of each part of the device can be determined according to needs as long as the corresponding functions can be achieved.

[0054] The implementation principle of a toner raw material conveying device according to an embodiment of the present application is as follows: During the working process, first, the driving member 51 is started, and the driving member 51 starts to draw air, so that the pressure in the driving cavity 23 and the accommodation cavity 21 gradually decreases; at this time, due to the action of the internal and external pressure difference, the first end of the feeding mechanism 3 sucks the toner raw material in the storage tank 9 into the accommodation cavity 21; the gas containing dust flows into the driving cavity 23 after being filtered by the first filtering mechanism 4; the driving member 51 continues to operate, enabling the toner raw material to be stably sucked into the accommodation cavity 21, and at the same time avoiding the pollution caused by a large amount of dust entering the driving cavity 23; moreover, the sliding plate 53 slides along the inner wall under the change of the air pressure in the driving cavity 23, which not only helps the air flow to be more evenly distributed in the entire space, but also can scrape and clean the second end of the connecting component and the inner side wall of the cylinder body 2 through its edge, thereby reducing the possibility of blockage, reducing the cleaning difficulty, and improving the reliability of the device.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
