Description

Technical Field

[0001] The utility model relates to the technical field of magnetic rollers, in particular to a connector and a magnetic roller. Background Art

[0002] Magnetic rollers are widely used in various industrial applications, particularly in material conveying and separation. Magnetic rollers attract metal materials through their powerful magnetic fields, effectively screening and separating them. With the continuous advancement of production technology, the requirements for the performance of magnetic rollers and their connection structures are also increasing. Traditional magnetic roller fixing joints typically use simple bolts or welds. While these structures can meet basic requirements in some applications, they have several drawbacks, including weak connections, easy loosening, cumbersome installation and removal, and a lack of sealing devices at the connection between the magnetic roller connector and the magnetic roller rod, which can lead to oil leakage. These issues not only affect the stability and safety of the equipment but also negatively impact production efficiency. Magnetic rollers may be subjected to vibration and impact during use, requiring connectors to not only provide a stable connection but also absorb certain mechanical stresses to prevent damage to the magnetic roller or related components. Therefore, developing a connector that addresses at least one of these technical issues is highly desirable. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a connecting head that can be installed on the magnetic roller. The magnetic roller includes a magnetic roller rod and a shell sleeved on the magnetic roller rod. The connecting head is in abutment against the magnetic roller rod and the shell. The connecting head includes a first connecting part, which is sleeved on the magnetic roller rod. A sealing part is provided between the first connecting part and the magnetic roller rod.

[0004] The connector provided in the embodiment of the present application can realize quick connection or disassembly of the connector and the magnetic roller through the first connecting part. By providing a sealing part between the connector and the magnetic roller rod, when the magnetic roller rod is inserted into the first connecting part, the sealing part is tightly fitted with the surface of the magnetic roller rod, which can effectively prevent oil from leaking from the connection between the connector and the magnetic roller rod, helping to improve the sealing performance between the connector and the magnetic roller rod and reduce oil leakage.

[0005] Optionally, the sealing portion is configured such that at least a portion thereof protrudes from an inner surface of the first connecting portion.

[0006] By adopting the above technical solution, at least a portion of the sealing portion protrudes from the inner surface of the first connecting portion, which can ensure that when the magnetic roller rod is inserted into the first connecting portion, the sealing portion is in full contact with the surface of the magnetic roller rod, which helps to improve the sealing effect. In addition, when the sealing portion has a certain degree of elasticity, the contact area between the sealing portion and the outer surface of the magnetic roller rod can be increased, and the influence of vibration and impact on the sealed connection between the sealing portion and the magnetic roller rod can also be reduced, which helps to further improve the sealing effect.

[0007] Optionally, the first connecting portion is provided with a receiving groove, and the sealing portion is received in the receiving groove.

[0008] By adopting the above technical solution, the sealing part is accommodated in the receiving groove of the first connecting part, which can accurately limit the position of the sealing part in the first connecting part, and can effectively prevent the sealing part from being displaced or damaged due to pressure changes or external forces during operation, thereby helping to improve the reliability of the connector.

[0009] Optionally, the sealing portion and the first connecting portion are integrally formed.

[0011] Optionally, the magnetic roller rod includes a second connecting portion, the first connecting portion is sleeved on the second connecting portion, and the sealing portion is provided between the first connecting portion and the second connecting portion.

[0012] By providing a second connecting portion for connecting to the first connecting portion on the magnetic roller rod, and the first connecting portion being sleeved on the second connecting portion, the connection between the magnetic roller rod and the first connecting portion can be made tighter and more stable. The plug-in connection structure can reduce the loosening or falling off of the magnetic roller rod during operation, improve the stability of the connection, and ensure the reliability of the magnetic roller when working under high load.

[0013] Optionally, the connector further includes a first inner cavity, which is communicated with the first connecting portion.

[0014] By adopting this technical solution, the provision of the first inner cavity allows the first connecting part to possess a certain degree of elasticity and deformation when subjected to force, thereby improving the adaptability of the system and reducing the risk of damage due to external forces. The first inner cavity can also be used to pre-tighten or pre-compress the magnetic roller, thereby enhancing its close fit with the first connecting part and improving overall stability and vibration resistance. Furthermore, the first inner cavity can be used to store sealing material, helping to prevent the intrusion of moisture and dust and protect the internal components. Alternatively, the first inner cavity can be used to store lubricant, helping to lubricate the connection during operation, reducing friction and wear, and thus extending the service life of the components. Furthermore, the first inner cavity can serve as an air pressure buffer, preventing the internal space of the first connecting part from being compressed too much when connected to the magnetic roller, resulting in a large air pressure difference and preventing installation.

[0015] Optionally, the sleeve is sleeved on the first connecting portion, the first connecting portion is provided with a first groove, and the first groove is located on the contact surface between the first connecting portion and the sleeve.

[0016] By adopting the above technical solution, the design of the first groove can effectively reduce the material usage of the first connecting part, thereby reducing the overall weight of the product and potentially reducing production costs. The shape of the first groove can enhance the structural rigidity of the first connecting part, making it less likely to deform when subjected to external forces, thereby helping to improve overall durability and stability. The first groove is located on the contact surface between the first connecting part and the casing, which can enhance the friction between the casing and the first connecting part and ensure the stability of the connection between the two. The first groove can also provide additional air circulation space, improve heat dissipation performance, and reduce the temperature of the device during operation. If the first groove is used in combination with an elastic material, it can enhance the vibration resistance of the device and provide a cushioning effect when subjected to impact or vibration.

[0017] Optionally, the connector further includes a limiting portion, the limiting portion is located at an end of the first connecting portion away from the magnetic roller rod, and the sleeve is sleeved on the first connecting portion and abuts against the limiting portion;

[0018] The connecting head further comprises a second groove, which is located at an end of the first connecting portion away from the magnetic roller rod.

[0019] By adopting the above technical solution, the limit part can serve as an additional support point to transmit the force to the casing, thereby enhancing the stability of the fixing part and preventing up and down or lateral displacement. The design of the limit part can limit the range of motion of the fixing part, avoid accidental displacement due to vibration or impact during operation, and ensure the safety and stability of the equipment operation. The limit part can provide a clear reference position for installation and alignment, making the installation process simpler and more efficient, and reducing possible human errors. By abutting against the casing, the limit part can share part of the load, reduce the direct friction between the fixing part and other components, thereby reducing wear and improving the durability of the component. The presence of the limit part can effectively enhance the structural stability of the entire device, so that the equipment can still maintain good working performance and life in a complex working environment.

[0020] The design of the second groove can reduce the amount of material used in the first connection part, thereby reducing the weight of the overall structure, helping to improve the efficiency of the equipment and reduce energy consumption. By designing the second groove, a certain gap can be formed between the first connection part and the casing, allowing the component to have a certain elastic deformation when subjected to force, improving the adaptability of the system, especially under vibration or impact conditions. If the equipment generates heat during operation, the presence of the second groove can increase the space for air circulation, help dissipate heat, and thus protect the equipment from overheating. The second groove can play a protective and guiding role, preventing other components or debris from getting stuck during operation, thereby improving the reliability of the equipment.

[0021] Optionally, the connector also includes a third connecting portion, which is connected to the end of the first connecting portion away from the magnetic roller rod; the third connecting portion includes a first connecting sub-portion, and a second connecting sub-portion connected to the first connecting sub-portion, and the first connecting sub-portion is connected to the first connecting portion; the first connecting sub-portion has a joint portion, and the second connecting sub-portion is provided with a accommodating cavity.

[0022] By adopting the above technical solution, the third connecting part is used to receive the external driving force. The connection design of the third connecting part and the first connecting part can improve the efficiency of power transmission, making the force transmission smoother, thereby improving the working efficiency of the entire equipment; the third connecting part is connected to the end of the first connecting part away from the magnetic roller rod, which can effectively reduce the impact of vibration during the driving force transmission process on the magnetic roller rod, and help improve the stability of the magnetic roller operation.

[0023] As the key component connecting the second and first connectors, the first connector effectively transmits power, ensuring excellent energy transfer efficiency during operation, thereby improving the overall performance of the device. By introducing the first connector between the second and fixed components, the structural stability of the assembly is increased, reducing the impact of external shock or vibration, and ensuring the robustness of the connection area. The first connector shares the direct force between the first and second connectors, reducing friction and wear between the contact surfaces, thereby extending the component's service life and reducing maintenance costs.

[0024] The setting of the joint portion of the first connecting sub-part facilitates the rotation of the first connecting sub-part. After the device is connected, the driving device of the device abuts against the joint portion to facilitate better power provision.

[0025] The accommodating cavity on the second connecting sub-section serves as an interface for connecting to other components, facilitating the connection and docking of external devices or other components, thereby increasing the system's flexibility and scalability. The accommodating cavity provides a clear positioning reference for assembly, facilitating docking and installation, reducing alignment errors, and improving assembly efficiency. The accommodating cavity design provides a more convenient access point, making inspection and maintenance easier, especially when replacing or inspecting components related to the mounting column, saving maintenance time and labor costs.

It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 As shown, an embodiment of the present invention provides a connector 200 that can be installed on a magnetic roller 100. The magnetic roller 100 includes a magnetic roller rod 110 and a housing 400 that is sleeved on the magnetic roller rod 110. The connector 200 abuts against the magnetic roller rod 110 and the housing 400. The connector 200 includes a first connecting portion 210 that is sleeved on the magnetic roller rod 110. A sealing portion 220 is provided between the first connecting portion 210 and the magnetic roller rod 110.

[0037] The magnetic roller rod 110 is the magnetic core portion in the middle of the magnetic roller 100 and is the main body of the magnetic roller 100 .

[0038] The housing 400 is a shell-like structure with a cavity structure. The cavity structure of the housing 400 is adapted to the magnetic roller rod 110. The housing 400 is sleeved on the magnetic roller rod 110 through the cavity structure. The length of the housing 400 can be slightly smaller than the overall length of the magnetic roller rod 110, ensuring that the housing 400 can provide protection for most of the magnetic roller rod 110.

[0039] The connector 200 abuts against the magnetic roller rod 110 and the housing 400. Specifically, the connector 200 includes a first connecting portion 210, which is sleeved onto the magnetic roller rod 110. The housing 400 sleeves onto the first connecting portion 210. The first connecting portion 210 has an inner cavity for accommodating the magnetic roller rod 110. The inner cavity of the first connecting portion 210 is adapted to fit the magnetic roller rod 110, and the magnetic roller rod 110 is accommodated within the inner cavity of the first connecting portion 210. The housing 400 can be a hollow cylindrical structure. The inner diameter of the housing 400 is the same as the outer diameter of the first connecting portion 210, allowing at least a portion of the first connecting portion 210 to be sleeved within the housing 400. The inner diameter of the housing 400 can also be slightly smaller than the outer diameter of the first connecting portion 210, ensuring a tight connection between the housing 400 and the first connecting portion 210 when the housing 400 is sleeved.

[0040] A sealing portion 220 is provided between the first connecting portion 210 and the magnetic roller rod 110. The sealing portion 220 is used to seal the connection between the first connecting portion 210 and the magnetic roller rod 110. There can be one or more sealing portions 220. When the magnetic roller rod 110 is inserted into the first connecting portion 210, the sealing portion 220 is in close contact with the surface of the magnetic roller rod 110.

[0041] Here, the sealing portion 220 can be an elastic component with a certain elasticity. When the magnetic roller rod 110 is assembled to the first connecting portion 210, the sealing portion 220 is elastically deformed and tightly adheres to the surface of the magnetic roller rod 110 with a certain pressure, which can further improve the sealing performance of the connection between the magnetic roller rod 110 and the first connecting portion 210.

[0042] The connector 200 provided in the embodiment of the present application can achieve quick connection or disassembly of the connector 200 and the magnetic roller 100 through the first connecting portion 210. By providing a sealing portion 220 between the connector 200 and the magnetic roller rod 110, when the magnetic roller rod 110 is inserted into the first connecting portion 210, the sealing portion 220 is tightly fitted with the surface of the magnetic roller rod 110, which can effectively prevent oil from leaking from the connection between the connector 200 and the magnetic roller rod 110, helping to improve the sealing performance between the connector 200 and the magnetic roller rod 110 and reduce oil leakage.

[0043] Optionally, the sealing portion 220 is configured such that at least a portion thereof protrudes from the inner surface of the first connecting portion 210. When the magnetic roller rod 110 is assembled into the inner cavity of the first connecting portion 210, the sealing portion 220 can be ensured to be in close contact with the surface of the magnetic roller rod 110 in the entire circumferential direction, thereby helping to improve the sealing effect. In addition, when the sealing portion 220 has a certain degree of elasticity, the contact area between the sealing portion 220 and the outer surface of the magnetic roller rod 110 can be increased, and the effects of vibration and impact on the sealed connection between the sealing portion 220 and the magnetic roller rod 110 can also be reduced, thereby helping to further improve the sealing effect.

[0044] Optionally, the first connecting portion 210 is provided with a receiving groove 211 , and the sealing portion 220 is received in the receiving groove 211 .

[0045] The receiving groove 211 is a groove-shaped structure formed by removing material from the inner cavity of the first connecting portion 210. The receiving groove 211 is adapted to fit the sealing portion 220. Specifically, the number of receiving grooves 211 is the same as the number of sealing portions 220, and the shape and size of the receiving grooves 211 can be the same as the shape and size of the sealing portion 220. When the sealing portion 220 is accommodated in the receiving groove 211, the sealing portion 220 is fixed in the receiving groove 211 by a snap fit, or can move slightly.

[0046] Preferably, the accommodating groove is located on a side of the first connecting portion 210 close to the inner cavity opening.

[0047] During installation, the sealing portion 220 can be first installed in the receiving groove 211 , and then the magnetic roller rod 110 can be inserted into the inner cavity of the first connecting portion 210 , so that one end of the sealing portion 220 is tightly attached to the surface of the magnetic roller rod 110 .

[0048] By adopting the above technical solution, the sealing part 220 is accommodated in the receiving groove 211 of the first connecting part 210, and the position of the sealing part 220 in the first connecting part 210 can be accurately limited, which can effectively prevent the sealing part 220 from being displaced or damaged due to pressure changes or external forces during operation, thereby helping to improve the reliability of the connector 200.

[0049] Optionally, the sealing portion 220 and the first connecting portion 210 are integrally formed, and the sealing portion 220 and the first connecting portion 210 are integrally formed into a whole, so that the connection between the sealing portion 220 and the first connecting portion 210 is tighter, and the gap or misalignment problem that may occur when the sealing portion 220 is assembled to the first connecting portion 210 due to production errors can be eliminated, which helps to improve the sealing effect and reliability of the connecting head 200.

[0050] Optionally, the magnetic roller rod 110 includes a second connecting portion 111 , the first connecting portion 210 is sleeved on the second connecting portion 111 , and the sealing portion 220 is disposed between the first connecting portion 210 and the second connecting portion 111 .

[0051] The second connecting portion 111 is the portion of the magnetic roller rod 110 that is connected to the first connecting portion 210 . The second connecting portion 111 is located at one end of the magnetic roller rod 110 . The second connecting portion 111 is adapted to the first connecting portion 210 and can be inserted into the inner cavity of the first connecting portion 210 .

[0052] Preferably, the magnetic roller rod 110 includes a main body and a second connecting part 111 connected to the main body. The size of the second connecting part 111 is smaller than the size of the main body of the magnetic roller rod 110. When the second connecting part 111 is inserted into the inner cavity of the first connecting part 210, the end of the first connecting part 210 can abut against the connection position between the main body and the second connecting part 111. Specifically, the end of the first connecting part 210 abuts against the end face of the main body, and the main body limits and positions the first connecting part 210 for installation, which helps to improve the accuracy and reliability of the connection between the magnetic roller 100 and the connector 200.

[0053] By providing a second connecting portion 111 on the magnetic roller rod 110 for connecting to the first connecting portion 210, and the first connecting portion 210 is sleeved on the second connecting portion 111, the connection between the magnetic roller rod 110 and the first connecting portion 210 can be made tighter and more stable. The plug-in connection structure can reduce the loosening or falling off of the magnetic roller rod 110 during operation, improve the stability of the connection, and ensure the reliability of the magnetic roller 100 when working under high load.

[0054] Optionally, the connector 200 further includes a first inner cavity 230 , which is in communication with the first connecting portion 210 .

[0055] The opening size of the first inner cavity 230 is smaller than the opening size of the inner cavity of the first connecting portion 210. For example, the first connecting portion 210, the inner cavity of the first connecting portion 210, and the first inner cavity 230 are all cylindrical, and the diameter of the first inner cavity 230 is smaller than the diameter of the inner cavity of the first connecting portion 210. Thus, when the magnetic roller rod 110 is assembled into the inner cavity of the first connecting portion 210, the connection between the first inner cavity 230 and the inner cavity of the first connecting portion 210 provides installation limit and positioning for the magnetic roller rod 110, helping to improve the precision and reliability of the connection between the magnetic roller 100 and the connector 200.

[0056] By adopting the above technical solution, the provision of the first inner cavity 230 enables the first connecting portion 210 to possess a certain degree of elasticity and deformation when subjected to force, thereby improving the adaptability of the system and reducing the risk of damage due to external forces. The first inner cavity 230 can also be used to pre-tighten or pre-compress the magnetic roller rod 110, thereby enhancing its close fit with the first connecting portion 210 and improving overall stability and vibration resistance. Furthermore, the first inner cavity 230 can be used to hold sealing material, helping to prevent the intrusion of moisture and dust and protect the safety of internal components. Alternatively, the first inner cavity 230 can be used to store lubricant, helping to lubricate the connection during operation, reducing friction and wear, and thus extending the service life of the components. Furthermore, the first inner cavity 230 can serve as an air pressure buffer, preventing the internal space of the first connecting portion 210 from being compressed too much when connected to the magnetic roller rod 110, resulting in a large air pressure difference and preventing installation.

[0057] Optionally, the sleeve 400 is sleeved on the first connection portion 210 , the first connection portion 210 is provided with a first groove 212 , and the first groove 212 is located on the contact surface between the first connection portion 210 and the sleeve 400 .

[0058] The housing 400 is sleeved onto the outer surface of the first connecting portion 210. The first groove 212 is a groove-like structure formed by removing material from the outer surface of the first connecting portion 210. The number of first grooves 212 can be one or more. The first groove 212 can extend in the same direction as the first connecting portion 210, or it can be arranged at an angle to the direction of extension of the first connecting portion 210.

[0059] Preferably, when a plurality of first grooves 212 are provided on the outer surface of the first connection portion 210 , the plurality of first grooves 212 are evenly distributed on the outer surface of the first connection portion 210 .

[0060] By adopting the above technical solution, the design of the first groove 212 can effectively reduce the material usage of the first connecting part 210, thereby reducing the overall weight of the product and potentially reducing production costs; the shape of the first groove 212 can enhance the structural rigidity of the first connecting part 210, making it less likely to deform when subjected to external forces, thereby helping to improve overall durability and stability; the first groove 212 is located on the contact surface between the first connecting part 210 and the casing 400, which can enhance the friction between the casing 400 and the first connecting part 210, ensuring the stability of the connection between the two. The first groove 212 can also provide additional air circulation space, improve heat dissipation performance, and reduce the temperature of the device during operation. If the first groove 212 is used in combination with an elastic material, it can enhance the vibration resistance of the device and provide a buffering effect when subjected to shock or vibration.

[0061] Optionally, the connector 200 further includes a limiting portion 240, which is located at an end of the first connecting portion 210 away from the magnetic roller rod 110, and the sleeve 400 is sleeved on the first connecting portion 210 and abuts against the limiting portion 240; the connector 200 further includes a second groove 213, which is located at an end of the first connecting portion 210 away from the magnetic roller rod 110.

[0062] In the radial direction of the first connecting portion 210, the limiting portion 240 protrudes outward along the outer surface of the first connecting portion 210. The outer diameter of the sleeve 400 is larger than the inner diameter of the sleeve 400. When the sleeve 400 is sleeved on the first connecting portion 210, one end of the sleeve 400 is axially limited by the limiting portion 240.

[0063] The second groove 213 is a groove structure obtained by removing material from the surface of the first connecting portion 210. There can be multiple second grooves 213, which are evenly distributed in the circumferential direction of the first connecting portion 210 and divide the limiting portion 240 into multiple parts.

[0064] By adopting the above technical solution, the limiting portion 240 can serve as an additional support point to transmit the force to the casing 400, thereby enhancing the stability of the fixing portion and preventing up and down or lateral displacement. The design of the limiting portion 240 can limit the range of motion of the fixing portion, avoid accidental displacement due to vibration or impact during work, and ensure the safety and stability of the equipment operation. The limiting portion 240 can provide a clear reference position for installation and alignment, making the installation process simpler and more efficient, and reducing possible human errors. By abutting against the casing 400, the limiting portion 240 can share part of the load, reduce the direct friction between the fixing portion and other components, thereby reducing wear and improving the durability of the component. The presence of the limiting portion 240 can effectively enhance the structural stability of the entire device, so that the equipment can still maintain good working performance and life in a complex working environment.

[0065] The design of the second groove 213 can reduce the material usage of the first connecting part 210, thereby reducing the weight of the overall structure, helping to improve the efficiency of the device and reduce energy consumption. By designing the second groove 213, a certain gap can be formed between the first connecting part 210 and the housing 400, so that the component can have a certain elastic deformation when subjected to force, thereby improving the adaptability of the system, especially under vibration or impact conditions. If the device generates heat during operation, the presence of the second groove 213 can increase the space for air circulation, help dissipate heat, and thus protect the device from overheating. The second groove 213 can play a protective and guiding role, preventing other components or debris from getting stuck during operation, thereby improving the reliability of the device.

[0066] Optionally, the connector 200 further includes a third connecting portion 300, which is connected to an end of the first connecting portion 210 away from the magnetic roller rod 110; the third connecting portion 300 includes a first connecting sub-portion 310 and a second connecting sub-portion 320 connected to the first connecting sub-portion 310, and the first connecting sub-portion 310 is connected to the first connecting portion 210; the first connecting sub-portion 310 has a coupling portion 311, and the second connecting sub-portion 320 is provided with a accommodating cavity 321.

[0067] The third connecting portion 300 is a portion of the connecting head 200 for receiving an external driving force.

[0068] The first connecting sub-part 310 is the portion of the third connecting part 300 connected to the first connecting part 210 , and the first connecting sub-part 310 can receive the driving force of an external driving device and transmit the driving force to the first connecting part 210 and the magnetic roller 100 , driving the magnetic roller 100 to rotate.

[0069] The engaging portion 311 is the portion of the first connecting sub-section 310 that engages with the external drive device. The engagement between the engaging portion 311 and the external drive device prevents slippage when the external drive device drives the first connecting sub-section 310. Preferably, the first connecting sub-section 310 is cylindrical, and the engaging portion 311 is a protrusion formed by cutting off several sections from the side surface of the first connecting sub-section 310.

[0070] The second connecting sub-section 320 is the portion of the third connecting section 300 that connects to other components. The accommodating cavity 321 is a hollow structure within the second connecting sub-section 320. The accommodating cavity 321 extends in the same direction as the second connecting sub-section 320. The connecting components in the device can be connected to the connector 200 and the magnetic roller 100 through the accommodating cavity 321, making the connection between the magnetic roller 100 and the device more stable.

[0071] By adopting the above technical solution, the third connecting part 300 is used to receive the external driving force.
