[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The defect of the tubular belt conveyor in the prior art is that the conveyor belt will twist during operation. When the conveyor belt is unfolded in the transition section of the head, the conveyor belt will move out of the roller due to excessive twisting, and even overlap, resulting in serious accidents and causing the conveyor to stop. The problem of conveyor belt deviation seriously affects the use of tubular belt conveyors.

[0032] In order to solve the above problems, the main concept adopted in this embodiment is: by arranging at least three rollers 22 in the circumferential direction of the surface of the No. 2 roller 21, a rolling groove matching the roller 22 is opened on the surface of the conveyor belt 3. During the transmission of the conveyor belt 3 on the surface of the No. 2 roller 21, the roller 22 cooperates with the rolling groove on the surface of the conveyor belt 3 to achieve the limiting effect of the conveyor belt, thereby reducing the risk of twisting of the conveyor belt 3 during the transmission process, which affects the normal use of the tubular belt conveyor.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods;

[0034] Embodiment 1:

[0035] The present invention provides an adaptive anti-twist tubular belt conveyor unit, comprising at least one set of transition components 1, at least one set of tubular components 2, a conveyor belt 3 and a base 4; the transition component 1 comprises three No. 1 rollers 11, the three No. 1 rollers 11 are arranged in an isosceles trapezoidal shape, the angle between the rollers on both sides of the transition component 1 and the ground increases as the distance between the rollers and the tubular component 2 decreases, the No. 1 rollers 11 are rotatably connected to the base 4, and the conveyor belt 3 is provided on the upper surface of the No. 1 rollers 11;

[0036] The tubular component 2 includes six No. 2 rollers 21, which are arranged in a hexagonal shape. The No. 2 rollers 21 are rotatably connected to the base 4. The surface of the No. 2 rollers 21 is provided with a conveyor belt 3, and the six No. 2 rollers 21 roll the conveyor belt 3 into a tubular shape;

[0037] At least three rollers 22 are circumferentially arranged on the surface of the second roller 21 , and rolling grooves matching the rollers 22 are opened on the surface of the conveyor belt 3 .

[0038] As a specific implementation of the present invention, at least two rollers 22 are provided axially of the No. 2 roller 21 and are evenly arranged in the axial direction.

[0039] The tubular belt conveyor is driven by friction. The conveyor belt 3 is rolled into an arc shape through the transition components 1 arranged at a certain interval at the head and tail ends of the tubular belt conveyor, and the conveyor belt 3 is forced to be rolled into a circular tube shape by using the tubular components 2 arranged at a certain interval. The material is fed from the head feeding section, and the conveyor belt changes from a flat shape to a U shape, and then gradually changes to an O shape through the transition section, wrapping the material for closed operation. When it is transported to the tail transition section, the circular tubular conveyor belt gradually expands from a U shape to a flat shape to unload the material;

[0040] However, the conveyor belt of the tubular belt conveyor may be twisted during operation. The present invention provides at least three rollers 22 on the surface of the second roller 21 in the circumferential direction, and provides rolling grooves matching the rollers 22 on the surface of the conveyor belt 3. During the transmission of the conveyor belt 3 on the surface of the second roller 21, the rollers 22 cooperate with the rolling grooves on the surface of the conveyor belt 3 to reduce the risk of circumferential movement of the conveyor belt 3 in the transition section, thereby achieving a limiting effect on the conveyor belt and reducing the risk of twisting of the conveyor belt 3 during the transmission process, which affects the normal use of the tubular belt conveyor.

[0041] At least two rollers 22 are axially arranged on the No. 2 idler 21 and are evenly arranged in the axial direction. Increasing the number of rollers 22 further increases the limiting points of the conveyor belt 3, thereby increasing the anti-twisting effect.

[0042] As a specific implementation of the present invention, the diameter of the second roller 21 gradually decreases from both sides to the middle.

[0043] As a specific implementation of the present invention, the surface of the second roller 21 is provided with rubber protrusions 211 .

[0044] The diameter of the No. 2 roller 21 gradually decreases from the two sides to the middle, so that the contact surface of the No. 2 roller 21 and the conveyor belt 3 is matched, thereby increasing the contact area between the No. 2 roller 21 and the conveyor belt 3. In addition, by providing rubber protrusions 211 on the surface of the No. 2 roller 21, the friction between the No. 2 roller 21 and the conveyor belt 3 is further increased, thereby improving the conveying capacity of the conveyor belt 3 and further reducing the risk of twisting of the conveyor belt 3.

[0045] As a specific implementation of the present invention, the roller 22 and the side wall of the rolling groove on the conveyor belt 3 are made of wear-resistant material.

[0046] Since the roller 22 and the rolling groove on the conveyor belt 3 cooperate with each other to prevent the conveyor belt 3 from twisting, there will be a certain amount of wear on the roller 22 and the side walls of the rolling groove during this process. By setting the side walls of the rolling groove on the roller 22 and the conveyor belt 3 to wear-resistant materials, such as polyurethane elastomer, the wear resistance of the roller 22 and the conveyor belt 3 is improved, thereby further improving the service life of the roller 22 and the conveyor belt 3.

[0047] As a specific embodiment of the present invention, a No. 1 magnet is provided on the bottom wall of the rolling groove of the conveyor belt 3, and a magnetic tube body 23 is provided in the middle of the tubular component 2. The magnetic tube body 23 is a tubular columnar object with magnetic force.

[0048] As a specific implementation of the present invention, the rubber protrusion 211 is magnetic rubber.

[0049] As a specific embodiment of the present invention, the magnetic tube body 23 passes through multiple tubular components 2 and is fixedly connected to the base 4 at both ends; multiple No. 2 magnets are fixedly connected to the surface of the magnetic tube body 23, and the No. 2 magnets are evenly arranged on the outer surface of the magnetic tube body 23.

[0050] A No. 1 magnet is provided on the bottom wall of the rolling groove on the conveyor belt 3, a magnetic tube body 23 is provided in the middle of the tubular component 2, the rubber protrusion 211 is a magnetic rubber, the N pole of the No. 1 magnet is set at the outer end, the S pole is set at the inner end, and the outer end of the magnetic rubber is set as the S pole. By using the principle of opposites attracting each other, the No. 1 magnet and the magnetic rubber generate suction force, so that the contact between the conveyor belt 3 and the roller 22 is closer; the S pole of the No. 2 magnet on the surface of the magnetic tube body 23 is set at the outer end, and by using the principle of like repels like, the magnetic tube body 23 and the No. 1 magnet generate repulsion, further making the contact between the conveyor belt 3 and the roller 22 closer, reducing the risk of the conveyor belt 3 being twisted, and improving the conveying capacity of the conveyor belt 3;

[0051] The working process of Example 1 is as follows:

[0052] The tubular belt conveyor is driven by friction. The conveyor belt 3 is rolled into an arc shape through the transition components 1 arranged at a certain interval at the head and tail ends of the tubular belt conveyor, and the conveyor belt 3 is forced to be rolled into a circular tube shape by using the tubular components 2 arranged at a certain interval. The material is fed from the head feeding section, and the conveyor belt changes from a flat shape to a U shape, and then gradually changes to an O shape through the transition section, wrapping the material for closed operation. When it is transported to the tail transition section, the circular tubular conveyor belt gradually expands from a U shape to a flat shape to unload the material;

[0053] However, the conveyor belt of the tubular belt conveyor may be twisted during operation. The present invention provides at least three rollers 22 on the surface of the second roller 21 in the circumferential direction, and provides rolling grooves matching the rollers 22 on the surface of the conveyor belt 3. During the transmission of the conveyor belt 3 on the surface of the second roller 21, the rollers 22 cooperate with the rolling grooves on the surface of the conveyor belt 3 to prevent the conveyor belt 3 from circumferentially moving in the transition section, thereby achieving a limiting effect on the conveyor belt and preventing the conveyor belt 3 from twisting during the transmission process, which affects the normal use of the tubular belt conveyor.

[0054] At least two rollers 22 are axially arranged on the No. 2 roller 21 and are evenly arranged in the axial direction. Increasing the number of rollers 22 further increases the limiting points of the conveyor belt 3, thereby increasing the anti-twist effect.

[0055] The diameter of the No. 2 roller 21 gradually decreases from the two sides to the middle, so that the contact surface of the No. 2 roller 21 and the conveyor belt 3 is matched, thereby increasing the contact area between the No. 2 roller 21 and the conveyor belt 3. In addition, by providing rubber protrusions 211 on the surface of the No. 2 roller 21, the friction between the No. 2 roller 21 and the conveyor belt 3 is further increased, thereby improving the conveying capacity of the conveyor belt 3 and further reducing the risk of twisting of the conveyor belt 3.

[0056] Since the roller 22 and the rolling groove on the conveyor belt 3 cooperate with each other to prevent the conveyor belt 3 from twisting, there will be a certain amount of wear on the roller 22 and the side walls of the rolling groove during this process. By setting the side walls of the rolling groove on the roller 22 and the conveyor belt 3 to wear-resistant materials, such as polyurethane elastomer, the wear resistance of the roller 22 and the conveyor belt 3 is improved, thereby further improving the service life of the roller 22 and the conveyor belt 3.

[0057] A No. 1 magnet is provided on the bottom wall of the rolling groove on the conveyor belt 3, a magnetic tube body 23 is provided in the middle of the tubular component 2, the rubber protrusion 211 is a magnetic rubber, the N pole of the No. 1 magnet is set at the outer end, the S pole is set at the inner end, and the outer end of the magnetic rubber is set as the S pole. By using the principle of opposites attracting each other, the No. 1 magnet and the magnetic rubber generate suction force, so that the contact between the conveyor belt 3 and the roller 22 is closer; the S pole of the No. 2 magnet on the surface of the magnetic tube body 23 is set at the outer end, and by using the principle of like repels like, the magnetic tube body 23 and the No. 1 magnet generate repulsion, further making the contact between the conveyor belt 3 and the roller 22 closer, reducing the risk of the conveyor belt 3 being twisted, and improving the conveying capacity of the conveyor belt 3;

[0060] The tubular component 2 includes six No. 2 rollers 21, which are arranged in a hexagonal shape. The No. 2 rollers 21 are rotatably connected to the base 4. The surface of the No. 2 rollers 21 is provided with a conveyor belt 3, and the six No. 2 rollers 21 roll the conveyor belt 3 into a tubular shape;

The material is fed from the head feeding section, and the conveyor belt changes from a flat shape to a U shape, and then gradually changes to an O shape through the transition section, wrapping the material for closed operation. When it is transported to the tail transition section, the circular tubular conveyor belt gradually expands from a U shape to a flat shape to unload the material;

[0064] However, the conveyor belt of the tubular belt conveyor may be twisted during operation. The present invention provides at least three rollers 22 on the surface of the second roller 21 in the circumferential direction, and provides rolling grooves matching the rollers 22 on the surface of the conveyor belt 3. During the transmission of the conveyor belt 3 on the surface of the second roller 21, the rollers 22 cooperate with the rolling grooves on the surface of the conveyor belt 3 to reduce the risk of circumferential movement of the conveyor belt 3 in the transition section, thereby achieving a limiting effect on the conveyor belt and reducing the risk of twisting of the conveyor belt 3 during the transmission process, which affects the normal use of the tubular belt conveyor.

[0066] As a specific implementation of the present invention, the diameter of the second roller 21 gradually decreases from both sides to the middle.

[0067] As a specific implementation of the present invention, the surface of the second roller 21 is provided with rubber protrusions 211 .

[0068] The diameter of the No. 2 roller 21 gradually decreases from the two sides to the middle, so that the contact surface of the No. 2 roller 21 and the conveyor belt 3 is matched, thereby increasing the contact area between the No. 2 roller 21 and the conveyor belt 3. In addition, by providing rubber protrusions 211 on the surface of the No. 2 roller 21, the friction between the No. 2 roller 21 and the conveyor belt 3 is further increased, thereby improving the conveying capacity of the conveyor belt 3 and further reducing the risk of twisting of the conveyor belt 3.

[0069] As a specific implementation of the present invention, the roller 22 and the side wall of the rolling groove on the conveyor belt 3 are made of wear-resistant material.

[0070] Since the roller 22 and the rolling groove on the conveyor belt 3 cooperate with each other to prevent the conveyor belt 3 from twisting, there will be a certain amount of wear on the roller 22 and the side walls of the rolling groove during this process.

An adaptive anti-twist tubular belt conveyor unit, comprising at least one set of transition components (1), at least one set of tubular components (2), a conveyor belt (3) and a base (4); characterized in that: The transition component (1) comprises three No. 1 rollers (11), the three No. 1 rollers (11) are arranged in an isosceles trapezoidal shape, the angle between the No. 1 rollers (11) on both sides of the transition component (1) and the ground increases as the distance between the No. 1 rollers (11) and the tubular component (2) decreases, the No. 1 rollers (11) are rotatably connected to the base (4), and a conveyor belt (3) is provided on the upper surface of the No. 1 rollers (11); The tubular component (2) comprises six No. 2 rollers (21), the six No. 2 rollers (21) are arranged in a hexagonal shape, the No. 2 rollers (21) are rotatably connected to the base (4), a conveyor belt (3) is provided on the surface of the No. 2 rollers (21), and the six No. 2 rollers (21) roll the conveyor belt (3) into a tubular shape; At least three rollers (22) are arranged circumferentially on the surface of the second roller (21), and rolling grooves matching the rollers (22) are opened on the surface of the conveyor belt (3); At least two rollers (22) are arranged axially on the No. 2 roller (21) and are evenly arranged in the axial direction; the diameter of the No. 2 roller (21) gradually decreases from both sides to the middle; rubber convex points (211) are provided on the surface of the No. 2 roller (21); and the side walls of the rolling grooves on the rollers (22) and the conveyor belt (3) are made of wear-resistant materials; A No. 1 magnet is provided on the bottom wall of the rolling groove on the conveyor belt (3); a magnetic tube body (23) is provided in the middle of the tubular component (2); the magnetic tube body (23) is a tubular columnar object with magnetic force; the rubber protrusion (211) is magnetic rubber; the magnetic tube body (23) passes through a plurality of tubular components (2) and is fixedly connected to the base (4) at both ends; a plurality of No. 2 magnets are fixedly connected to the surface of the magnetic tube body (23); the No. 2 magnets are evenly arranged on the outer surface of the magnetic tube body (23); The number of the tubular components (2) is two and they are arranged longitudinally. The two tubular components (2) have a common No. 2 roller (21), so that the two tubular components (2) can simultaneously drive two conveyor belts (3) for transportation. On the one hand, the tubular components (2) have a common No. 2 roller (21), which reduces the number of parts and makes the structure more compact. On the other hand, due to the existence of the common No. 2 roller (21), the transportation directions of the upper and lower conveyor belts must be opposite to each other, so as to realize two-way transportation.
