Description

Technical Field

[0001] This application relates to the field of logistics conveying technology, and in particular to a roller curved conveyor. Background Technology

[0002] A roller conveyor with curves is a mechanical device used for material transport. It consists of multiple parallel rollers that drive goods to move along a preset path by rotating. It is specially designed to achieve curves and turns in the horizontal plane. Its features include the use of conical rollers or differential speed layout. It is widely used in continuous conveying systems in industries such as packaging, warehousing, and logistics, and is suitable for the curved transport needs of regular items such as boxes and pallets.

[0003] While belt drives can achieve significant power transmission in roller curved conveyors, they also have obvious drawbacks: high-speed belt operation can generate considerable noise due to friction with rollers, bearings, and other components, affecting the working environment; at the same time, their enclosed or compact structural design makes lubrication and maintenance difficult, and long-term operation can lead to insufficient lubrication, resulting in accelerated wear of components and further reducing equipment stability and service life. Utility Model Content

[0004] To address the aforementioned problems of high noise levels and difficulty in adding and maintaining lubricating oil in belt drives, this application provides a roller curved conveyor.

[0005] The technical solution of the roller curved conveyor provided in this application is as follows:

[0006] A curved roller conveyor includes a curved conveyor belt, a transmission roller at the top of the curved conveyor belt, a drive motor at the bottom of the curved conveyor belt, the drive motor driving the transmission roller via a belt, multiple oil injection cylinders fixedly connected to the top of the curved conveyor belt, a partition plate fixedly connected inside the oil injection cylinder, a bottom block at the bottom of the partition plate, the bottom block fixedly connected to the inner wall of the oil injection cylinder, a plug block fitted inside the bottom block, a toothed column fixedly connected to the top of the plug block, a gear meshing with one side of the toothed column, a small motor fixedly connected to one side of the gear, a connecting pipe fixedly connected to the bottom of the oil injection cylinder, and a dripper fixedly connected to the bottom of the connecting pipe, the dripper being located above the belt.

[0007] Preferably, the curved conveyor belt is fixedly connected to both sides with a rim, a damping spring is fixedly connected to one side of the rim, a protective plate is fixedly connected to one end of the damping spring, and an arc-shaped plate is fixedly connected to one end of the protective plate.

[0009] Preferably, a stop block is fixedly connected to the top of the toothed column, and the toothed column is slidably connected to the top of the oil injection cylinder.

[0010] Preferably, the curvature of the protective sheet is adapted to the curvature of the curved conveyor belt.

[0011] Preferably, a guide nozzle is fixedly connected to the bottom of the dripping device, and the guide nozzle is made of silicone.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. A small motor drives the gears, toothed column, and plug to move, and together with the oil injection cylinder, connecting pipe, and dripper, it realizes the automatic addition of lubricating oil to the belt and transmission roller. The dripper uses the weight and surface tension of the lubricating oil to drip stably, effectively reducing the noise caused by friction during belt drive, reducing component wear, and improving equipment stability and service life.

[0014] 2. The protective structure consists of the side edging, damping springs, protective plates, and arc-shaped plates on both sides of the curved conveyor belt.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Reference Figure 1-6 This utility model provides a curved roller conveyor, including a curved conveyor belt 1, a transmission roller 101 at the top of the curved conveyor belt 1, a drive motor 102 at the bottom of the curved conveyor belt 1, the drive motor 102 drives the transmission roller 101 through a belt, multiple oil injection cylinders 3 are fixedly connected to the top of the curved conveyor belt 1, a partition plate 304 is fixedly connected inside the oil injection cylinder 3, a bottom block 305 is provided at the bottom of the partition plate 304, the bottom block 305 is fixedly connected to the inner wall of the oil injection cylinder 3, a plug block 404 is attached to the inside of the bottom block 305, a toothed column 402 is fixedly connected to the top of the plug block 404, a gear 401 is meshed with one side of the toothed column 402, a small motor 4 is fixedly connected to one side of the gear 401, a connecting pipe 5 is fixedly connected to the bottom of the oil injection cylinder 3, and a dripper 501 is fixedly connected to the bottom of the connecting pipe 5, the dripper 501 is located above the belt.

[0024] When the roller conveyor starts, the drive motor 102 operates, driving the transmission roller 101 to rotate via the belt. The transmission roller 101 then drives the curved conveyor belt 1 to transport materials. During equipment operation, if lubrication is required at the connection points between the belt and the transmission roller 101 and the drive motor 102, the small motor 4 is started. The small motor 4 drives the gear 401 to rotate, and the gear 401 meshes with the toothed column 402, causing the toothed column 402 to move up and down. The toothed column 402 drives the stopper block 404 to move up and down within the bottom block 305. When the stopper block 404 moves upward and disengages from the bottom block 305, the lubricating oil in the oil injection cylinder 3 flows through the space below the partition plate 304 to the bottom block 305, then enters the dripper 501 through the connecting pipe 5, and finally drips the lubricating oil onto the belt. The partition plate 304 provides a certain degree of separation and buffering for the lubricating oil in the oil injection cylinder 3, preventing a large amount of lubricating oil from flowing down instantly.

[0025] The 501 dripper is a device capable of precisely dispensing liquids. Its working principle is based on pressure difference and physical structure design. Inside the device, there is typically a storage chamber for storing the liquid to be dispensed, which is connected to the drip outlet via a specific channel. When dispensing is needed, lubricating oil drips into the storage chamber, propelling the liquid through the channel to the drip outlet. The specific model is LubrimaticLD-10, which is existing technology and will not be described in detail here.

[0026] In a preferred embodiment, the curved conveyor belt 1 is fixedly connected to both sides of the side edge 103, a damping spring 203 is fixedly connected to one side of the side edge 103, a protective plate 2 is fixedly connected to one end of the damping spring 203, and an arc-shaped plate 201 is fixedly connected to one end of the protective plate 2.

[0027] During the material conveying process of the curved conveyor belt 1, when the material may deviate to both sides due to centrifugal force or other factors at the curve, the material will first come into contact with the arc-shaped plate 201. After the arc-shaped plate 201 is subjected to the force of the material, it transmits the force to the protective plate 2. The protective plate 2 compresses the damping spring 203, and the damping spring 203 deforms to generate elastic force, which buffers the impact force of the material on the arc-shaped plate 201. The surrounding edge 103 provides an installation and support base for the damping spring 203 and the protective plate 2.

[0028] In a preferred embodiment, one end of the oil injection cylinder 3 is fixedly connected to an oil injection port 302, and the surface of the oil injection cylinder 3 is provided with an observation window 301.

[0029] When the lubricating oil in the oil filling cylinder 3 is insufficient, lubricating oil is added to the oil filling cylinder 3 through the oil filling port 302. The lubricating oil enters the oil filling cylinder 3 through the oil filling port 302, and the operator can observe the level of the lubricating oil in the oil filling cylinder 3 at any time through the observation window 301.

[0030] In a preferred embodiment, a stop block 403 is fixedly connected to the top of the toothed column 402, and the toothed column 402 is slidably connected to the top of the oil injection cylinder 3.

[0031] As the small motor 4 drives the gear 401 to rotate, causing the gear 402 to move up and down, the stop block 403 moves along with the gear 402. When the gear 402 moves upward to a certain position, the stop block 403 contacts the top of the oil injection cylinder 3, limiting the gear 402 from moving further upward; when the gear 402 moves downward, the stop block 403 also prevents the gear 402 from moving excessively downward and disengaging from the gear 401.

[0032] In a preferred embodiment, the curvature of the protective plate 2 is adapted to the curvature of the curved conveyor belt 1.

[0033] This adaptive arc design makes the protective plate 2 and the arc plate 201 more effective at blocking misaligned materials, and can more comprehensively prevent materials from falling, thus improving the safety and stability of material conveying.

[0034] In a preferred embodiment, a flow guide nozzle is fixedly connected to the bottom of the dripper 501, and the flow guide nozzle is made of silicone.

[0035] The silicone guide nozzle improves the accuracy of lubricant dripping and avoids lubricant waste.

[0036] The foregoing description of an exemplary embodiment of a roller curved conveyor provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
