[0028] The present invention proposes a material transfer device 100.

[0029] Please see Figure 1 and Figure 2In one embodiment of the present invention, the material conveying 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 enclose 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, and 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 move the end of the pressing block 43 away from the second driving member 41 closer to or away from the conveyor belt 32.

[0030] In one embodiment, the base 1 is generally a stable platform capable of supporting the weight of the entire material transfer device 100 and the load during operation. The design must consider the installation of the guide rails 11, ensuring that they can be fixed to the base 1 and remain aligned. The material of the base 1 needs sufficient strength and rigidity; commonly used materials include steel (such as carbon steel or stainless steel), aluminum alloy, cast iron, or polymer composites. Stainless steel is a common choice due to its corrosion resistance, high strength, and ease of cleaning. Aluminum alloys are chosen for their lightweight and good mechanical properties, making them particularly suitable for applications requiring weight reduction. The surface of the base 1 may undergo special treatments, such as painting, electroplating, or anodizing, to improve corrosion resistance and abrasion resistance. In some cases, the surface may be sandblasted to increase friction and prevent slippage. The size and shape of the base 1 are determined based on the design of the material transfer device 100 and the needs of the production environment. The base 1 needs to be designed to withstand vibrations and shocks 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 drive element 2 is typically a motor, hydraulic pump, cylinder, or other type of drive device. In the material transfer device 100, the first drive element 2 drives the conveyor belt 32 to transfer the material sheets. Specifically, the first drive element 2 is directly connected to the drive wheel 31, and the rotation of the motor drives the drive wheel 31, thereby driving the conveyor belt 32. A frequency converter or reducer can be used to control the speed of the first drive element 2 to adjust the conveying speed of the conveyor belt 32. The transmission assembly 3 is a key component of the material transfer device 100; its function is to transmit power from the first drive element 2 to the conveyor belt 32 to achieve continuous material transport. The transmission assembly 3 typically includes a drive wheel 31 and a conveyor belt 32. The drive wheel 31 is directly connected to the first drive element 2, and its rotation is the direct source of the movement of the conveyor belt 32. The drive wheel 31 can be a single wheel or multiple wheels (such as two or three wheels), depending on the required torque and stability. The conveyor belt 32 is a flexible strip of material that contacts and is driven by the drive wheel 31, typically made of rubber, plastic, metal, or other synthetic materials. The conveyor belt 32 wraps around the drive wheel 31 and other possible deflectors, transmitting power through friction or meshing. The first drive element 2 is the power source for the transmission assembly 3, typically an electric motor, but can also be a hydraulic motor, pneumatic motor, or other type of drive device. The output shaft of the drive element is connected to the drive wheel 31, driving the conveyor belt 32 by rotating the drive wheel 31. To ensure effective contact of the conveyor belt 32 with the drive wheel 31 and reduce slippage, the conveyor belt 32 needs to maintain appropriate tension. The tensioning device can be a weight, spring, hydraulic or pneumatic cylinder, etc., used to adjust the tension of the conveyor belt 32.

[0032] In this embodiment, the pressing assembly 4 is the part of the conveying device 100 used to press or release materials, and its purpose is to ensure the stability of materials during the conveying process. 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 the power source of the pressing assembly 4, which can be a motor, cylinder, or other linear drive device, and is 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, used to transmit power. The pressing block 43 is the 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 realize the pressing and releasing actions. 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 will cause the pressing block 43 to rotate around the base 1. One end of the pressing block 43 can move closer to or further away from the conveyor belt 32 under the drive of the second driving member 41, thereby realizing the pressing or releasing of materials. The pressing assembly 4 ensures the stability of the material on the conveyor belt 32, preventing displacement or detachment during transport. The design of the pressing block 43 allows it to accommodate materials of varying thicknesses, ensuring proper application of clamping force. The entire pressing process can be automated, improving efficiency and reducing manual intervention.

[0033] The technical solution of this invention involves designing a material transfer 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, which guides the movement path of the conveyor belt 32. The transmission assembly 3 consists 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 cylinder) and is responsible for driving the operation of the conveyor belt 32. The conveyor belt 32 extends along the extension direction of the guide rail 11 and forms a clamping channel 3a with the guide rail 11 for clamping and transferring materials. The pressing assembly 4 consists 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 its output end is connected to the connecting block 42. The connecting block 42 is then movably connected to the pressing block 43. When the second driving member 41 drives the connecting block 42 to move, it in turn drives the pressing block 43 to rotate around the base 1. This rotation allows one end of the pressure block 43 to move closer to or further away from the conveyor belt 32, thereby enabling the clamping or release of materials of different thicknesses on the conveyor belt 32. The movement of the pressure block 43 allows the material conveying device 100 to adapt to materials of different thicknesses, ensuring the stability of the material during conveying. By adjusting the position of the pressure block 43, the clamping force of the material can be easily controlled, preventing the material from slipping or falling off during conveying.

[0034] In one embodiment of the present invention, please refer to Figure 3 The pressing assembly 4 also includes a fixing block 44, which is connected to the base 1, and the pressing block 43 is rotatably connected to the fixing 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 to ensure that the fixed block 44 remains stable during the pressing process. A pressing block 43 is rotatably connected to the fixed block 44 via a pivot or hinge, allowing the pressing block 43 to rotate under the support of the pivot or hinge of the fixed block 44. When the second driving component 41, such as a servo motor or cylinder, is activated, it drives the pressing block 43 to rotate via the connecting block 42. One end of the pressing block 43 moves closer to or further away from the conveyor belt 32, thus pressing or releasing the material on the conveyor belt 32. This design allows the pressing block 43 to swing or move parallel around the fixed block 44 as a fulcrum, thereby adapting to materials of different thicknesses and ensuring the stability and transmission quality of the material during the conveying process.

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

[0037] In this embodiment, the pressure block 43 is designed with two bent sections, namely a first bent section 431 and a second bent section 432, both of which are bent towards the direction of the pressure block 43 facing the conveyor belt 32. This design allows the pressure block 43 to provide a more uniform pressure distribution when compressing materials, while increasing the contact area between the pressure block 43 and the conveyor belt 32, thereby improving the compaction effect and the stability of the material. Specifically, the pressure block 43 consists of a first bent section 431 and a second bent section 432. The first bent section 431 is the part close to the connecting block 42. When the pressure block 43 is driven by the second driving member 41, the first bent section 431 rotates, and drives the second bent section 432 to rotate through the fixing block 44. This makes the second bent section 432 firmly compress the material. Both bent sections are bent towards the direction of the pressure block 43 facing the conveyor belt 32. This design helps the second bent section 432 of the pressure 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 pressure block 43 and ensuring the stability of the pressure block 43 when pressing and releasing materials. A spring can also be provided between the connecting block 42 and the first bending section 431 to ensure better reset of the second bending section 432. This design of the pressure block 43 not only improves the pressing effect, but also enables the material pressing assembly 4 to adapt to materials of different sizes and shapes, enhancing the flexibility and applicability of the material conveying device 100.

[0038] In one embodiment of the present invention, please refer to Figure 4 The pressing assembly 4 also includes a pressure roller 45, which is rotatably connected to the second bending section 432. The pressure roller 45 is located at the end of the second bending section 432 away from the fixed block 44 and faces the side of the conveyor belt 32.

[0039] In one embodiment, the pressing assembly 4 further includes a pressure roller 45, which enhances the compaction effect on the material and ensures the stability of the material during conveying. The pressure roller 45 is rotatably connected to the second bent section 432 of the pressing block 43 via bearings, hinges, or other rotating mechanisms. This design allows the pressure roller 45 to rotate as the pressing block 43 moves to accommodate materials of different thicknesses. The pressure roller 45 is located at the end of the second bent section 432 away from the fixed block 44, meaning that when the pressing block 43 moves to compact or release the material, the pressure roller 45 can provide additional pressure support from the other side. The pressure roller 45 is designed to face the conveyor belt 32 to ensure maximum contact surface with the material on the conveyor belt 32, thereby providing uniform and stable compaction force. The second bent section 432 is part of the design of the pressing block 43 and is rotatably connected to the pressure roller 45, ensuring that the pressure roller 45 can rotate as the second bent section 432 moves to accommodate materials in different positions. This design enables the material transfer device 100 to handle materials of different types and sizes more reliably, improving the adaptability and efficiency of the entire system.

[0040] In one embodiment of the present invention, please refer to Figure 4 The pressing assembly 4 also includes a friction ring 46, which is detachably connected to the outer peripheral arm of the pressure roller 45.

[0041] In this embodiment, the friction ring 46 in the pressing assembly 4 of the material conveying device 100 is designed to enhance the friction between the pressure roller 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 outer peripheral arm of the pressure roller 45 via a detachable connection method, such as using bolts, clips, or wedges. This design allows the friction ring 46 to be easily installed or replaced when needed. The connection between the pressure roller 45 and the friction ring 46 can be direct or achieved through an intermediate component (such as a bushing). This connection method needs to be able to withstand a certain pressure and friction while allowing a certain range of adjustment to accommodate materials of different thicknesses. Since the friction ring 46 is detachable, it can be quickly replaced when worn or damaged, reducing maintenance time and costs. The advantage of this design is that it provides an adjustable clamping mechanism, enabling the material conveying device 100 to adapt to different types and sizes of materials, improving the flexibility and reliability of the entire system.

[0042] In one embodiment of the present invention, please refer to Figure 3 and Figure 4 The guide rail 11 has a clamping groove 11a, which is connected to the clamping channel 3a, and the pressure roller 45 is movably inserted through the clamping groove 11a.

[0043] In this embodiment, the guide rail 11 has a clamping groove 11a, which is used to accommodate the pressure roller 45, ensuring that the pressure roller 45 can effectively apply pressure to the material on the conveyor belt 32. Specifically, the guide rail 11 is a component in the material conveying device 100 used to guide and fix the conveyor belt 32, and is usually fixed to the base 1. The guide rail 11 has a clamping groove 11a, which is a special groove used to guide and accommodate part of the pressure roller 45. The clamping groove 11a communicates with the clamping channel 3a, which is a space formed by the conveyor belt 32 and the guide rail 11 for clamping the material. The clamping groove 11a ensures that the pressure roller 45 can move along the groove, thereby adjusting the clamping force on the material. The pressure roller 45 is part of the pressing assembly 4, and it is movably inserted into the clamping groove 11a and can move along the clamping groove 11a. The pressure roller 45 is usually made of wear-resistant material to withstand long-term pressure and friction. The pressure roller 45 can move freely within the clamping groove 11a. This design allows the pressure roller 45 to be adjusted according to the thickness and width of the material to achieve the best clamping effect. By moving the position of the pressure roller 45 in the clamping groove 11a, the pressure applied by the pressure roller 45 to the material on the conveyor belt 32 can be adjusted. This adjustment can be performed manually or through an automated control system. Because the pressure roller 45 is located within the clamping groove 11a, maintenance and replacement can be easily performed without disassembling the entire guide rail 11. This design provides operational flexibility, enabling the material conveying device 100 to adapt to materials of different sizes and types, improving the system's adaptability and reliability.

[0044] In one embodiment of the present invention, please refer to Figure 3 The transmission assembly 3 also includes a stop bar 33, which is detachably connected to the base 1 and is located on the side of the clamping channel 3a facing away from the pressure block 43.

[0045] In one embodiment, the transmission assembly 3 further includes a stop bar 33, which serves to support the weight of the material in the conveyor belt 32 and prevent the material from shifting or falling off during conveying. Specifically, the stop bar 33 is a strip-shaped component installed along one side of the clamping channel 3a. It is detachably connected to the base 1, such as by bolts, snap-fit ​​connections, or other quick-release mechanisms, so that it can be quickly installed or removed when needed. The stop bar 33 is located on the side of the clamping channel 3a opposite to the pressure block 43, so that it can work in conjunction with the pressure block 43 to fix the material from two directions. The connection between the stop bar 33 and the base 1 can be either directly fixed to the base 1 or it can be moved within a certain range via a guide rail 11 or other mechanisms to accommodate materials of different widths. The stop bar 33 is typically made of wear-resistant materials, such as plastic, rubber, metal, or other materials with moderate hardness that are not easily damaged by the material. The main function of the baffle 33 is to act as part of the clamping channel 3a, forming 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 component to fix and guide the material, ensuring the stability and efficiency of the material during conveying.

[0046] In one embodiment of the present invention, please refer to Figure 4 The pressing assembly 4 also includes a fine-tuning bolt 47. The pressing block 43 has a threaded hole 43a. The pressing block 43 is screwed to the fine-tuning bolt 47 through the cooperation of the fine-tuning bolt 47 and the threaded hole 43a.

[0047] In this embodiment, the pressure assembly 4 also includes a fine-tuning bolt 47, which is introduced to achieve precise adjustment of the distance between the pressure block 43 and the guide rail 11. Specifically, the pressure block 43 has threaded holes 43a, which are used to engage with the fine-tuning bolt 47 to achieve fine adjustment of the position of the pressure block 43. The fine-tuning bolt 47 is a screw with threads that match the threaded holes 43a of the pressure block 43. The fine-tuning bolt 47 can be adjusted manually, electrically, or pneumatically for more precise control. The pressure block 43 is screwed together by the engagement of the fine-tuning bolt 47 with the threaded holes 43a. This connection method allows the operator to move the pressure block 43 along the guide rail 11 by rotating the fine-tuning bolt 47, thereby adjusting the distance between the pressure block 43 and the conveyor belt 32. When it is necessary to adjust the position of the pressure block 43, it can be achieved by rotating the fine-tuning bolt 47. Rotating the fine-tuning bolt 47 causes the pressure block 43 to move along the guide rail 11, thereby changing the pressure exerted by the pressure block 43 on the material on the conveyor belt 32. This fine-tuning mechanism allows the material conveying device 100 to adapt to materials of different thicknesses and types, ensuring the stability and transmission quality of the material during the conveying process.

[0048] This invention also proposes a plasma cleaning device, which includes a material transfer device 100 and a cleaning device. The specific structure of the material transfer device 100 is as described in the above embodiments. Since this plasma cleaning device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The cleaning device is used to clean the material transferred from 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, providing a highly efficient and environmentally friendly cleaning solution. The material transfer device 100 is responsible for accurately transferring materials to the cleaning device, while the cleaning device utilizes plasma technology to perform deep cleaning of the materials. The design of the material transfer device 100 considers the stability and efficiency of material transfer. It includes a base 1 with guide rails 11 on it for guiding and supporting the movement of the conveyor belt 32. A first drive element 2, typically a motor, drives the conveyor belt 32 through a transmission assembly 3 (including a transmission wheel 31 and the conveyor belt 32). The conveyor belt 32 and the guide rails 11 form a clamping channel 3a for clamping and transferring materials. To accommodate materials of different thicknesses, the material transfer device 100 also includes a pressing assembly 4, which, through a combination of a second drive element 41, a connecting block 42, and a pressing block 43, achieves the clamping and release of materials. The pressing block 43 is designed with a first bending section 431 and a second bending section 432, both bending towards the conveyor belt 32 to accommodate materials of different thicknesses. The cleaning device utilizes the high energy of plasma to clean dirt and grease from the material surface. Plasma is a high-energy, highly reactive ionized substance that can effectively remove contaminants from material surfaces. The cleaning device typically includes a cleaning chamber where the material is cleaned by plasma. The working principle of the plasma cleaner is to generate plasma to clean dirt and grease from the surface of the material sheet. Its main functions include cleaning and activating the surface, improving wettability, enhancing adhesion, and surface etching. This plasma cleaning equipment design not only improves cleaning efficiency and quality but also ensures the stability and adaptability of material transport through the optimized design of the material transfer device 100, making it suitable for cleaning needs of various materials and complex structures.
