[0028] The present invention provides a material conveying device 100 .

[0029] See also Figure 1 and Figure 2In one embodiment of the present invention, the material transmission device 100 includes: a base 1, a first driving member 2, a transmission assembly 3 and a pressing assembly 4, the base 1 is provided with a guide rail 11; the transmission assembly 3 includes a transmission wheel 31 and a conveyor belt 32, the output end of the first driving member 2 is connected to the transmission wheel 31, and the transmission wheel 31 abuts against the conveyor belt 32; the conveyor belt 32 and the guide rail 11 are surrounded to form a clamping channel 3a; the first driving member 2 can drive the transmission wheel 31 to rotate so that the conveyor belt 32 slides relative to the base 1; the pressing assembly 4 includes a second driving member 41, a connecting block 42 and a pressing block 43, the second driving member 41 is connected to the guide rail 11, the output end of the second driving member 41 is connected to the connecting block 42, the connecting block 42 is movably connected to the pressing block 43, and the pressing block 43 is rotatably connected to the base 1; the second driving member 41 can drive the connecting block 42 to drive the pressing block 43 away from the end of the second driving member 41 to approach or move away from the conveyor belt 32.

[0030] In one embodiment, the base 1 is generally a stable platform that can support the weight of the entire material transfer device 100 and the load during operation. The installation of the guide rail 11 needs to be considered during design to ensure that the guide rail 11 can be fixed on the base 1 and remain aligned. The material of the base 1 needs to have sufficient strength and rigidity, and commonly used materials include steel (such as carbon steel or stainless steel), aluminum alloy, cast iron or polymer composite materials. Stainless steel is a common choice because it is corrosion-resistant, strong and easy to clean. Aluminum alloy is selected because of its light weight and good mechanical properties, especially for applications that need to reduce overall weight. The surface of the base 1 may be specially treated, such as painting, electroplating or anodizing, to improve corrosion resistance and wear resistance. In some cases, the surface may be frosted to increase friction and prevent sliding. The size and shape of the base 1 will be determined according to the design of the material transfer device 100 and the needs of the production environment. The base 1 needs to be designed to resist vibration and impact during operation to maintain stability. The base 1 also needs to be compatible with existing production lines or equipment for easy integration and maintenance.

[0031] In one embodiment, the first driving member 2 is usually a motor, a hydraulic pump, a cylinder or other forms of driving devices. In the material transmission device 100, the function of the first driving member 2 is to drive the conveyor belt 32 to realize the transmission of the material sheet. Specifically, the first driving member 2 is directly connected to the transmission wheel 31, and the transmission wheel 31 is driven by the rotation of the motor, thereby driving the conveyor belt 32. A variable frequency drive or a reducer can be used to control the speed of the first driving member 2 to adjust the transmission speed of the conveyor belt 32. The transmission assembly 3 is a key part in the material transmission device 100. Its function is to transfer power from the first driving member 2 to the conveyor belt 32 to realize continuous transportation of materials. The transmission assembly 3 usually includes a transmission wheel 31 and a conveyor belt 32. The transmission wheel 31 is directly connected to the first driving member 2, and its rotation is the direct source of the movement of the conveyor belt 32. The transmission wheel 31 can be a single wheel or multiple wheels (such as double wheels or three wheels), and the specific design depends on the required torque and stability. The conveyor belt 32 is a flexible belt material that contacts and is driven by the transmission wheel 31, and is usually made of rubber, plastic, metal or other synthetic materials. The conveyor belt 32 is wrapped around the transmission wheel 31 and other possible redirecting wheels, and transmits power through friction or meshing. The first drive member 2 is the power source of the transmission assembly 3, which is usually an electric motor, but can also be a hydraulic motor, a pneumatic motor or other types of driving devices. The output shaft of the drive member is connected to the transmission wheel 31, and the conveyor belt 32 is driven by rotating the transmission wheel 31. In order to ensure effective contact of the conveyor belt 32 on the transmission wheel 31 and reduce slippage, the conveyor belt 32 needs to maintain appropriate tension. The tensioning device can be a weight, a spring, a hydraulic or pneumatic cylinder, etc., which is used to adjust the tightness of the conveyor belt 32.

[0032] In this embodiment, the material pressing assembly 4 is a part of the material conveying device 100 used for pressing or releasing the material, and its purpose is to ensure the stability of the material during the conveying process. The material pressing assembly 4 includes a second driving member 41, a connecting block 42 and a pressing block 43; the second driving member 41 is the power source of the material pressing assembly 4, which can be a motor, a cylinder or other linear driving device, responsible for driving the connecting block 42 to move. The connecting block 42 is an intermediate component between the output end of the second driving member 41 and the pressing block 43, which is used to transmit power. The pressing block 43 is a component that directly contacts the material and applies pressure, and is usually movably connected to the connecting block 42 and rotatably connected to the base 1 to achieve the action of pressing and releasing. Specifically, when the second driving member 41 is activated, it drives the connecting block 42 to move, and the movement of the connecting block 42 drives the pressing block 43 to rotate around the base 1. One end of the pressing block 43 can be driven by the second driving member 41 to move close to or away from the conveyor belt 32, thereby achieving the pressing or releasing of the material. The pressing assembly 4 can ensure the stability of the material on the conveyor belt 32 and prevent the material from shifting or falling off during the conveying process. The design of the pressing block 43 allows it to adapt to materials of different thicknesses and ensure the proper application of the pressing force. The entire pressing process can be automatically controlled to improve efficiency and reduce manual intervention.

[0033] The technical solution of the present invention is to design a material conveying device 100, which includes a base 1, a first driving member 2, a transmission assembly 3 and a pressing assembly 4. The base 1 is provided with a guide rail 11; the base 1 is equipped with a guide rail 11 for guiding the moving path of the conveyor belt 32. The transmission assembly 3 is composed of a transmission wheel 31 and a conveyor belt 32. The transmission wheel 31 is connected to the output end of the first driving member 2 (such as a motor or a cylinder driving member) and is responsible for driving the operation of the conveyor belt 32. The conveyor belt 32 is enclosed with the guide rail 11 along the extension direction of the guide rail 11 to form a clamping channel 3a for clamping and conveying materials. The pressing assembly 4 is composed of a second driving member 41, a connecting block 42 and a pressing block 43. The second driving member 41 is connected to the guide rail 11 and is connected to the connecting block 42 through its output end. The connecting block 42 is movably connected to the pressing block 43. When the second driving member 41 drives the connecting block 42 to move, it drives the pressing block 43 to rotate around the base 1. This rotation allows one end of the pressing block 43 to move closer to or farther from the conveyor belt 32, thereby achieving compression or release of materials of different thicknesses on the conveyor belt 32. The movement of the pressing block 43 allows the material conveying device 100 to adapt to materials of different thicknesses and ensure the stability of the materials during the conveying process. By adjusting the position of the pressing block 43, the clamping force of the material can be easily controlled to prevent the material from sliding or falling off during the conveying process.

[0034] In one embodiment of the present invention, see Figure 3 The pressing assembly 4 further includes a fixed block 44 , which is connected to the base 1 , and the pressing block 43 is rotatably connected to the fixed block 44 .

[0035] In one embodiment, the pressing assembly 4 includes a fixed block 44, which is connected to the base 1 by bolts or welding, etc., to ensure that the fixed block 44 remains stable and motionless during the pressing process. The pressing block 43 is rotatably connected to the fixed block 44 through a rotating shaft or a hinge, so that the pressing block 43 can rotate under the support of the rotating shaft or hinge of the fixed block 44. When the second driving member 41, such as a servo motor or a cylinder, is activated, the pressing block 43 is driven to rotate through the connecting block 42, and one end of the pressing block 43 moves closer to or away from the conveyor belt 32, thereby achieving the compression or release of the material on the conveyor belt 32. This design allows the pressing block 43 to swing or move in parallel with the fixed block 44 as a fulcrum, so as to adapt to materials of different thicknesses and ensure the stability and transmission quality of the material during the transmission process.

[0036] In one embodiment of the present invention, see Figure 4 and Figure 5 The pressing block 43 has a first bending section 431 close to the connecting block 42 and a second bending section 432 away from the connecting block 42 ; the first bending section 431 and the second bending section 432 are both bent in the direction of the pressing block 43 facing the conveyor belt 32 .

[0037] In this embodiment, the design of the pressing block 43 has two bending sections, namely the first bending section 431 and the second bending section 432, which are bent toward the direction of the pressing block 43 facing the conveyor belt 32. Such a design enables the pressing block 43 to provide a more uniform pressure distribution when pressing the material, and at the same time increases the contact area between the pressing block 43 and the conveyor belt 32, thereby improving the pressing effect and the stability of the material. Specifically, the pressing block 43 is composed of the first bending section 431 and the second bending section 432. The first bending section 431 is the part close to the connecting block 42. When the pressing block 43 is driven by the second driving member 41, the first bending section 431 rotates and drives the second bending section 432 to rotate through the fixing block 44. The second bending section 432 firmly presses the material. Both bending sections are bent toward the direction of the pressing block 43 facing the conveyor belt 32. Such a design helps the second bending section 432 of the pressing block 43 to more closely press the material on the conveyor belt 32, preventing the material from sliding or shifting during the conveying process. The fixing block 44 is fixedly connected to the base 1, providing a stable support point for the pressing block 43, ensuring the stability of the pressing block 43 when pressing and releasing the material. A spring can also be arranged between the connecting block 42 and the first bending section 431 to ensure that the second bending section 432 can be better reset. This design of the pressing block 43 not only improves the pressing effect, but also enables the pressing assembly 4 to adapt to materials of different sizes and shapes, thereby enhancing the flexibility and application range of the material conveying device 100.

[0038] In one embodiment of the present invention, see Figure 4 The pressing assembly 4 further includes a pressing wheel 45 , which is rotatably connected to the second bending section 432 , and is located at one end of the second bending section 432 away from the fixing block 44 and facing one side of the conveyor belt 32 .

[0039] In one embodiment, the material pressing assembly 4 further includes a pressing wheel 45, which is used to enhance the pressing effect on the material and ensure the stability of the material during the conveying process. The pressing wheel 45 is rotatably connected to the second bending section 432 of the pressing block 43 through a bearing, a hinge or other rotating mechanism. Such a design allows the pressing wheel 45 to rotate with the pressing block 43 when it moves to adapt to materials of different thicknesses. The pressing wheel 45 is located at one end of the second bending section 432 away from the fixed block 44, which means that when the pressing block 43 moves to press or release the material, the pressing wheel 45 can provide additional pressure support from the other side. The pressing wheel 45 is designed to face the side of the conveyor belt 32 to ensure that the contact surface with the material on the conveyor belt 32 is maximized, thereby providing a uniform and stable pressing force. The second bending section 432 is a part of the design of the pressing block 43, which is rotatably connected to the pressing wheel 45 to ensure that the pressing wheel 45 can rotate with the movement of the second bending section 432 to adapt to materials at different positions. This design enables the material conveying device 100 to more reliably handle materials of different types and sizes, thereby improving the adaptability and efficiency of the entire system.

[0040] In one embodiment of the present invention, see Figure 4 The pressing assembly 4 further includes a friction ring 46 , which is detachably connected to the peripheral arm of the pressing wheel 45 .

[0041] In this embodiment, in the material pressing assembly 4 of the material conveying device 100, the friction ring 46 is designed to enhance the friction between the pressure wheel 45 and the conveyor belt 32, thereby ensuring the stability of the material during the conveying process. Specifically, the friction ring 46 is connected to the peripheral arm of the pressure wheel 45 by a detachable connection method, such as using bolts, buckles or wedges, etc. This design allows the friction ring 46 to be easily installed or replaced when needed. The connection between the pressure wheel 45 and the friction ring 46 can be direct or through an intermediate piece (such as a sleeve). This connection method needs to be able to withstand a certain pressure and friction, while allowing a certain range of adjustment to adapt to materials of different thicknesses. Since the friction ring 46 is detachable, it can be quickly replaced when worn or damaged, reducing maintenance time and cost. The advantage of this design is that it provides an adjustable clamping mechanism, allowing the material conveying device 100 to adapt to materials of different types and sizes, improving the flexibility and reliability of the entire system.

[0042] In one embodiment of the present invention, see Figure 3 and Figure 4 The guide rail 11 is provided with a clamping groove 11a, the clamping groove 11a is communicated with the clamping channel 3a, and the pressing wheel 45 is movably arranged in the clamping groove 11a.

[0043] In this embodiment, the guide rail 11 is provided with a clamping groove 11a, which is for accommodating the pressure wheel 45 to ensure that the pressure wheel 45 can effectively apply pressure to the material on the conveyor belt 32. Specifically, the guide rail 11 is a component in the material transmission device 100 for guiding and fixing the conveyor belt 32, and is usually fixed on the base 1. The guide rail 11 is provided with a clamping groove 11a, which is a special groove for guiding and accommodating part of the pressure wheel 45. The clamping groove 11a is connected to the clamping channel 3a, which is a space for clamping the material formed by the conveyor belt 32 and the guide rail 11. The setting of the clamping groove 11a ensures that the pressure wheel 45 can move along the groove, thereby adjusting the clamping force on the material. The pressure wheel 45 is a part of the material pressing assembly 4, which is movably arranged in the clamping groove 11a and can move along the clamping groove 11a. The pressure wheel 45 is usually made of wear-resistant material to withstand long-term pressure and friction. The pressure wheel 45 can move freely in the pressing groove 11a. This design allows the pressure wheel 45 to be adjusted according to the thickness and width of the material to achieve the best pressing effect. By moving the position of the pressure wheel 45 in the pressing groove 11a, the pressure applied by the pressure wheel 45 to the material on the conveyor belt 32 can be adjusted. This adjustment can be made manually or through an automated control system. Since the pressure wheel 45 is located in the pressing groove 11a, it can be easily maintained and replaced without disassembling the entire guide rail 11. This design provides operational flexibility, allowing the material conveying device 100 to adapt to materials of different sizes and types, and improving the adaptability and reliability of the system.

[0044] In one embodiment of the present invention, see Figure 3 The transmission assembly 3 further includes a baffle 33 , which is detachably connected to the base 1 , and is located on a side of the clamping channel 3 a facing away from the pressing block 43 .

[0045] In one embodiment, the transmission assembly 3 further includes a baffle 33, which is used to bear the weight of the material in the conveyor belt 32 to prevent the material from deflecting or falling off during the conveying process. Specifically, the baffle 33 is a strip-shaped component installed along one side of the clamping channel 3a, and it is connected to the base 1 in a detachable manner, such as bolt connection, snap connection or other quick loading and unloading mechanism, so that it can be quickly installed or removed when needed. The baffle 33 is located on the side of the clamping channel 3a that is away from the pressure block 43, that is, the side opposite to the pressure block 43, so that it can work with the pressure block 43 to fix the material from two directions. The connection between the baffle 33 and the base 1 can be directly fixed on the base 1, or it can be allowed to move within a certain range through a guide rail 11 or other mechanisms to adapt to materials of different widths. The baffle 33 is usually made of wear-resistant materials, such as plastic, rubber, metal or other materials with moderate hardness and not easy to damage the material. The main function of the baffle 33 is to serve as a part of the clamping channel 3a, and to form a closed channel together with the conveyor belt 32 and the pressure block 43 to ensure the stability of the material during the conveying process. This design provides a simple part to fix and guide the material, ensuring the stability and transmission efficiency of the material during the conveying process.

[0046] In one embodiment of the present invention, see Figure 4 The pressing assembly 4 further includes a fine-tuning bolt 47. The pressing block 43 is provided with a threaded hole 43a. The pressing block 43 is threadedly connected with the fine-tuning bolt 47 through the cooperation between the fine-tuning bolt 47 and the threaded hole 43a.

[0047] In the present embodiment, the press assembly 4 further includes a fine-tuning bolt 47, the introduction of which is to achieve precise adjustment of the distance between the press block 43 and the guide rail 11. Specifically, threaded holes 43a are provided on the press block 43, and these threaded holes 43a are used to cooperate with the fine-tuning bolts 47 to achieve fine-tuning of the position of the press block 43. The fine-tuning bolt 47 is a screw rod having threads matching the threaded holes 43a of the press block 43. The fine-tuning bolt 47 can be adjusted manually, or it can be adjusted electrically or pneumatically to achieve more precise control. The press block 43 is screwed together by the cooperation of the fine-tuning bolt 47 and the threaded hole 43a. This connection mode allows the operator to push the press block 43 to move along the guide rail 11 by rotating the fine-tuning bolt 47, thereby adjusting the distance between the press block 43 and the conveyor belt 32. When the position of the press block 43 needs to be adjusted, it can be achieved by rotating the fine-tuning bolt 47. Rotating the fine-tuning bolt 47 causes the pressing block 43 to move along the guide rail 11, thereby changing the pressure applied by the pressing block 43 to the material on the conveyor belt 32. This fine-tuning mechanism enables the material conveying device 100 to adapt to materials of different thicknesses and types, ensuring the stability and transmission quality of the materials during the conveying process.

[0048] The present invention also provides a plasma cleaning device, which includes a material transfer device 100 and a cleaning device. The specific structure of the material transfer device 100 refers to the above embodiment. Since the present plasma cleaning device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the cleaning device is used to clean the material transferred by the material transfer device 100.

[0049] In this embodiment, the plasma cleaning equipment proposed by the present invention includes a material transfer device 100 and a cleaning device, which is an efficient and environmentally friendly cleaning solution. The material transfer device 100 is responsible for accurately transferring the material to the cleaning device, while the cleaning device uses plasma technology to deeply clean the material. The design of the material transfer device 100 takes into account the stability and efficiency of material transmission. It includes a base 1, on which a guide rail 11 is provided for guiding and supporting the movement of a conveyor belt 32. A first driving member 2, usually a motor, drives the conveyor belt 32 to operate through a transmission assembly 3 (including a transmission wheel 31 and a conveyor belt 32). The conveyor belt 32 and the guide rail 11 enclose a clamping channel 3a for clamping and conveying materials. In order to adapt to materials of different thicknesses, the material transfer device 100 also includes a material pressing assembly 4, which realizes the pressing and releasing of the material through a combination of a second driving member 41, a connecting block 42 and a pressing block 43.
