Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, specifically to a carbon fiber core roller. Background Technology

[0002] As a key component of the conveyor belt, the main roller is often placed in key positions such as the end or middle. When used as a drive roller, it rotates continuously under the drive of a motor, and drives the conveyor belt to move back and forth by means of the friction generated between it and the conveyor belt.

[0003] Application number CN201710299004.8 discloses a roller with a replaceable shaft. The roller includes a cylinder body, side plates disposed on a large-hole side plate shoulder ring and a small-hole side plate shoulder ring, and a main shaft passing through the two shoulder rings; the cylinder body is internally supported by the two side plates; the two ends of the main shaft have two different sizes of fit with the two side plate shoulder rings, while the outer diameter of the shoulder rings is the same;

[0004] When the main roller is used as the drive roller, it mainly relies on friction to drive the external conveyor belt to carry out transportation activities. After a long period of use, the surface of the main roller will wear down, resulting in some debris on the surface. This debris makes it easier for the conveyor belt to slip between the main roller and the main roller. Slippage will affect the transport of the conveyor belt, and at the same time, slippage will aggravate wear, further affecting the transport. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a carbon fiber core roller to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a carbon fiber shaft main roller, comprising a carbon fiber shaft made of carbon fiber material, a polyurethane shell fixedly connected to the outer wall of the carbon fiber shaft, the polyurethane shell being made of polyurethane material, an adsorption component fixedly connected inside the polyurethane shell, and an air blowing component fixedly connected inside the polyurethane shell. In use, the carbon fiber shaft is fixed to the corresponding transport frame, and the leather transport belt is movably connected to the polyurethane shell on the outside of the carbon fiber shaft. The side of the carbon fiber shaft away from the external fixed rod is connected to the transport drive device, allowing the drive device to drive the carbon fiber shaft to rotate, and the carbon fiber shaft drives the transport belt through the polyurethane shell for transport activities.

[0007] The adsorption components include:

[0008] The suction cup tube is fixedly connected inside the polyurethane shell and penetrates the inner wall of the carbon fiber core.

[0009] A barrier ring, which is fixedly connected to the inner wall of the suction cup tube;

[0010] A barrier disc is disposed on the outside of a barrier ring.

[0011] Preferably, several suction tubes are provided, and a soft opening is provided on the outside of the suction tube. When the blocking ring and the blocking circle are attached, they will block the suction tube and hinder the flow of air. The suction tube will play the same role as the suction cup.

[0012] Preferably, a first spring is fixedly connected to the outer side of the blocking disc, and an inner fixing plate is fixedly connected to the outer side of the first spring. The inner fixing plate is fixedly connected to the inner wall of the suction cup tube. The first spring will push against the blocking disc, so that the blocking disc fits with the blocking ring. When the outer side of the suction cup tube fits with the inner wall of the conveyor belt, the suction cup tube will produce the same effect as a suction cup to stick to the inner wall of the conveyor belt.

[0013] Preferably, a second spring is fixedly connected to the inner side of the barrier ring, and a movable push rod is fixedly connected inside the second spring located inside the barrier disc, and the maximum diameter of the outer wall of the movable push rod is smaller than the minimum inner diameter of the suction cup tube.

[0014] Preferably, a ball bearing is movably connected to the inner side of the second spring, and a cylindrical camshaft is movably connected to the inside of the carbon fiber shaft through a bearing. The second spring pushes the movable push rod downward, causing the outer wall of the ball bearing to fit against the outer wall of the cylindrical camshaft. An external fixing rod is fixedly connected to the front of the cylindrical camshaft. During use, the external fixing rod is fixedly connected to the fixed structure of the conveyor device. The external fixing rod is fixed to the external fixed structure to prevent the cylindrical camshaft from rotating with the carbon fiber shaft when it rotates. Since the cylindrical camshaft is fixed to the external fixed structure through the external fixing rod, when the carbon fiber shaft is driven to rotate, the suction tube will rotate around the cylindrical camshaft. When the conveyor belt is about to separate from the suction tube, the ball bearing will roll onto the protruding part of the cylindrical camshaft. Since the distance between the protruding part of the cylindrical camshaft and the shaft center of the cylindrical camshaft increases, the protruding part will cause the movable push rod to push outward to block the disc.

[0015] Preferably, the air blowing assembly includes an internal spiral plate. The carbon fiber shaft is driven to rotate by an external drive device, which causes the internal spiral plate to rotate. The rotation of the internal spiral plate will continuously push the outside air into the interior of the carbon fiber shaft. The internal spiral plate is fixedly connected to the inner wall of the carbon fiber shaft, and an air baffle plate is fixedly connected to the inner wall of the internal spiral plate on the back of the cylindrical camshaft.

[0016] Preferably, the gas baffle plate will seal the internal cross section of the carbon fiber shaft. When the carbon fiber shaft is driven to rotate around the shaft, the internal spiral plate will push the external gas towards the gas baffle plate. When the movable top rod pushes open the blocking disc, the gas pushed by the internal spiral plate will be blocked by the gas baffle plate, and then the gas pushed by the internal spiral plate will enter the suction cup tube and then be discharged to the outside.

[0017] Preferably, a guide rod is movably connected inside the internal fixing plate, an air guide plate is fixedly connected to the outside of the guide rod, and a third spring is fixedly connected to the inside of the air guide plate. The inside of the third spring is fixedly connected to the outside of the internal fixing plate. During the process of the conveyor belt and the suction tube being in contact, the conveyor belt will also push the air guide plate into the suction tube, causing the third spring to contract. The air guide plate will maintain a certain pressure with the conveyor belt under the push of the third spring.

[0018] This invention provides a carbon fiber core roller. It has the following advantages:

[0019] 1. The carbon fiber shaft main roller, through the first spring, pushes against the blocking disc, causing the blocking disc to fit with the blocking ring. When the outer side of the suction tube fits against the inner wall of the conveyor belt, a suction cup effect is generated to hold the inner wall of the conveyor belt, enhancing the force between the suction tube and the conveyor belt. This reduces the frequency of sliding between the conveyor belt and the polyurethane shell surface, reduces wear between the polyurethane shell and the conveyor belt, and thus avoids wear affecting transportation.

[0020] 2. The carbon fiber shaft main roller, through the air guide plate, will maintain a certain pressure with the conveyor belt under the push of the third spring. Since the internal fixing plate restricts the position of the air guide plate, it will enhance the friction between the suction tube and the conveyor belt when the suction tube is holding the conveyor, thereby reducing the wear of the conveyor belt and avoiding the impact of wear on the transportation.

[0021] 3. The carbon fiber shaft main roller continuously pushes outside air into the carbon fiber shaft through the rotation of the internal spiral plate, allowing the gas to enter the suction tube and then be discharged outward. The air guide plate blocks the airflow, causing it to blow in all directions. The airflow acts on the surface of the polyurethane shell, blowing away debris from the surface of the polyurethane shell. This prevents wear debris from causing the conveyor belt to slide against the polyurethane shell surface, reducing wear on the conveyor belt during use and thus preventing wear from affecting transportation.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0033] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a carbon fiber shaft main roller, including a carbon fiber shaft 1, the carbon fiber shaft 1 is made of carbon fiber material, a polyurethane shell 2 is fixedly connected to the outer wall of the carbon fiber shaft 1, the polyurethane shell 2 is made of polyurethane material, an adsorption component 3 is fixedly connected inside the polyurethane shell 2, and an air blowing component 4 is fixedly connected inside the polyurethane shell 2.

[0034] Adsorption component 3 includes:

[0035] The suction tube 301 is fixedly connected inside the polyurethane shell 2 and penetrates the inner wall of the carbon fiber shaft 1.

[0036] The barrier ring 305 is fixedly connected to the inner wall of the suction cup tube 301;

[0037] The blocking disc 304 is disposed outside the blocking ring 305.

[0038] The carbon fiber shaft 1 is fixed on the corresponding transport frame, and the leather transport belt is movably connected to the polyurethane shell 2 on the outside of the carbon fiber shaft 1. The side of the carbon fiber shaft 1 away from the external fixing rod 309 is connected to the transport drive device, so that the drive device can drive the carbon fiber shaft 1 to rotate, and the carbon fiber shaft 1 drives the transport belt to carry out transport activities through the polyurethane shell 2.

[0039] Several suction tubes 301 are provided. A soft opening is provided on the outside of the suction tube 301. When the blocking ring 305 and the blocking circle 304 are attached, they will block the suction tube 301 and hinder the flow of air. The suction tube 301 will play the same role as the suction cup.

[0040] A first spring 303 is fixedly connected to the outer side of the blocking disc 304, and an inner fixing plate 302 is fixedly connected to the outer side of the first spring 303. The inner fixing plate 302 is fixedly connected to the inner wall of the suction tube 301.

[0041] The first spring 303 will push against the blocking disc 304, causing the blocking disc 304 to fit against the blocking ring 305. When the carbon fiber shaft 1 rotates, it will cause the outer side of the suction tube 301 to fit against the inner wall of the conveyor belt. After the fit, the suction tube 301 will have the same effect as a suction cup to stick to the inner wall of the conveyor belt, which will enhance the force between the suction tube 301 and the conveyor belt. This will reduce the frequency of sliding between the conveyor belt and the surface of the polyurethane shell 2, and reduce the wear between the polyurethane shell 2 and the conveyor belt.

[0042] A second spring 307 is fixedly connected to the inner side of the blocking ring plate 305. Inside the second spring 307, a movable push rod 306 is fixedly connected to the inner side of the blocking disc 304. The maximum diameter of the outer wall of the movable push rod 306 is smaller than the minimum inner diameter of the suction tube 301.

[0043] The second spring 307 is movably connected to the inner side of a ball bearing 310. The carbon fiber shaft 1 is movably connected to a cylindrical camshaft 308 via a bearing. The second spring 307 pushes the movable push rod 306 downward, causing the outer wall of the ball bearing 310 to fit against the outer wall of the cylindrical camshaft 308. The cylindrical camshaft 308 is fixedly connected to an external fixing rod 309 on its front side. During use, the external fixing rod 309 is fixedly connected to the fixed structure of the conveyor device. The external fixing rod 309 is fixed to the external fixing structure to keep the cylindrical camshaft 308 from rotating with the carbon fiber shaft 1. When the conveyor belt is about to separate from the suction tube 301, the ball bearing 310 will roll onto the protruding part of the cylindrical camshaft 308. Since the distance between the protruding part of the cylindrical camshaft 308 and the shaft of the cylindrical camshaft 308 increases, the protruding part will cause the movable push rod 306 to push outward to block the disc 304.

[0044] Since the cylindrical camshaft 308 is fixed to the external fixed structure by the external fixed rod 309, when the carbon fiber shaft 1 is driven to rotate, the suction tube 301 will rotate around the cylindrical camshaft 308. The movable push rod 306 will be rotated by the suction tube 301, and the ball bearings 310 on the outer wall of the movable push rod 306 will roll on the surface of the cylindrical camshaft 308. When the conveyor belt is about to separate from the suction tube 301, the ball bearings 310 will roll to the protruding part on the cylindrical camshaft 308. This protruding part will cause the movable push rod 306 to push the blocking disc 304 outward, creating a gap between the blocking disc 304 and the blocking ring 305, thereby connecting the inner cavity of the formed suction cup with the outside world, allowing the internal air pressure to connect with the outside, causing the suction cup to lose its suction force, and allowing the conveyor belt to easily separate from the suction tube 301.

[0045] Example 2: Please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution:

[0046] The air blowing assembly 4 includes an internal spiral plate 401, which is fixedly connected to the inner wall of the carbon fiber shaft 1. An air baffle plate 402 is fixedly connected to the inner wall of the internal spiral plate 401 on the back of the cylindrical camshaft 308.

[0047] The air baffle plate 402 serves to seal the internal cross-section of the carbon fiber shaft 1. When the carbon fiber shaft 1 is driven to rotate around the shaft, the internal spiral plate 401 pushes the external gas toward the air baffle plate 402. When the movable push rod 306 pushes open the blocking disc 304, the gas pushed by the internal spiral plate 401 is blocked by the air baffle plate 402, and then the gas pushed by the internal spiral plate 401 enters the suction tube 301 and is discharged to the outside.

[0048] The carbon fiber shaft 1 is driven to rotate by an external drive device, which causes the internal spiral plate 401 to rotate. The rotation of the internal spiral plate 401 continuously pushes outside air into the carbon fiber shaft 1. Since the air baffle plate 402 blocks the flow of gas, when the suction tube 301 moves to the protruding part of the cylindrical camshaft 308, the movable push rod 306 pushes open the blocking disc 304. At this time, the internal spiral plate 401 pushes the gas into the suction tube 301 and then discharges it to the outside.

[0049] A guide rod 404 is movably connected inside the internal fixing plate 302. An air guide plate 403 is fixedly connected to the outside of the guide rod 404. A third spring 405 is fixedly connected to the inside of the air guide plate 403, and the inside of the third spring 405 is fixedly connected to the outside of the internal fixing plate 302. The conveyor belt pushes the air guide plate 403 into the suction tube 301, causing the third spring 405 to contract. The air guide plate 403 will maintain a certain pressure with the conveyor belt under the push of the third spring 405.

[0050] During the process of the conveyor belt and the suction tube 301 being in contact, the conveyor belt will also push the air guide plate 403 into the suction tube 301, causing the third spring 405 to contract. The air guide plate 403 will maintain a certain pressure with the conveyor belt under the push of the third spring 405. Furthermore, since the internal fixing plate 302 restricts the position of the air guide plate 403, when the suction tube 301 is holding the conveyor belt, the outer side of the air guide plate 403 will enhance the friction between the suction tube 301 and the conveyor belt, thereby reducing the wear of the conveyor belt.

[0051] When the conveyor belt separates from the surface of the polyurethane shell 2, the air guide plate 403 will be reset under the push of the third spring 405. At this time, the suction tube 301 will discharge the airflow generated by the internal spiral plate 401. This airflow will be blocked by the air guide plate 403 and blown in all directions. This airflow will act on the surface of the polyurethane shell 2 to blow away the debris on the surface of the polyurethane shell 2, so as to prevent the wear debris from causing the conveyor belt to slide on the surface of the polyurethane shell 2.

[0052] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
