Description

Technical Field

[0001] This invention relates to the field of logistics conveying technology, specifically to a slope conversion conveyor and its conveying method. Background Technology

[0002] Logistics transportation is a core technology that relies on transportation or warehousing and transshipment systems to achieve automated and continuous transfer of goods in production, warehousing, sorting and other stages.

[0003] With the rapid development of modern logistics transportation, automated production lines and warehousing and transfer systems, it is often necessary to transport materials under different slopes. Moreover, on-site working conditions often present problems such as the need to adjust the conveying slope. Existing conveying equipment generally has problems such as fixed slope, easy spillage or jamming during slope transitions, and the need for multiple transfer machines between high and low positions, slopes and planes. Traditional inclined conveyors have inadvertently fixed or cumbersome tilt angles and cannot adapt to multi-slope working conditions on site.

[0004] To address the aforementioned issues, we propose a slope conversion conveyor. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a slope-converting conveyor and its conveying method. By setting up a continuously adjustable slope and slope conversion function, the conveying section can flexibly switch between horizontal and uphill sections. It can achieve a smooth transition between different slopes without the need for multiple transfer devices. Compared with traditional fixed slope or cumbersome adjustment conveying equipment, this application can make stepless adjustments according to the actual slope requirements on site, which significantly improves the adaptability and versatility of the conveying equipment to different sites and effectively solves the problem of frequent equipment replacement or modification due to inconsistent site slopes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a slope conversion conveyor, comprising a fixed frame and a support frame disposed on one side of the fixed frame. A double-output shaft right-angle geared motor is fixedly installed on the top of the support frame. A first sprocket is fixedly installed on each of the two output ends of the double-output shaft right-angle geared motor. Protective covers are provided on opposite sides inside the support frame. A second sprocket is rotatably installed on the lower side inside the protective cover. A lifting chain belt is meshed between the corresponding first sprocket and the corresponding second sprocket. Through openings are provided on opposite sides of the two protective covers. Two combined blocks are fixedly installed on one side of the surface of the two lifting chain belts. An adjusting frame is fixedly installed on the surface of the two corresponding combined blocks. Two conveyor belts are rotatably installed between the two adjusting frames and the fixed frame. Protective components are provided on the front and rear sides of the surface of the two conveyor belts. The protective component includes a protective arc groove block fixedly installed on one side of the conveyor belt surface. The inner wall of the protective arc groove block is slidably fitted with a protective arc block. Two T-shaped guide grooves are opened on the lower side of the inner wall of the protective arc groove block. T-shaped connecting blocks are slidably installed on the inner walls of the two T-shaped guide grooves. A push groove plate is fixedly installed on the top of the two T-shaped connecting blocks. A push component is provided on the left side of the push groove plate, and a reset component is provided on the right side of the inner wall of the two T-shaped guide grooves. Several inclined support blocks are rotatably installed on the inner wall of the push groove plate.

[0007] Furthermore, the two output ends of the dual-output shaft right-angle geared motor are rotatably connected to the left and right sides of the top of the support frame, respectively. This rotatable connection is achieved through a rotating shaft assembly. The output ends of the dual-output shaft right-angle geared motor can rotate freely relative to the top of the support frame. The protective cover is fixedly installed inside the support frame, and the upper part of the protective cover extends upward to above the top surface of the support frame. Its extended part completely covers the first sprocket, so that the first sprocket is located in the internal cavity enclosed by the protective cover, thereby preventing foreign objects from entering the sprocket meshing area.

[0008] Furthermore, the access opening on the surface of the protective cover is an elongated through hole extending in the vertical direction. A portion of each of the two assembly blocks passes through the corresponding access opening and extends to the outer surface of the protective cover. The portion of the assembly block located on the outside of the protective cover is fixedly connected to the adjustment frame. By moving the assembly block up and down along the elongated direction of the access opening, the adjustment frame can be vertically adjusted relative to the support frame.

[0009] Furthermore, both conveyor belts are multi-row parallel chain belt structures, and when the adjusting frame moves up and down, the conveyor belts can rotate around the fixed frame, thereby adjusting the slope of the conveyor belts.

[0010] Furthermore, the protective arc trough block is an arc-shaped trough plate structure, with its two ends curving upwards relative to the surface of the conveyor belt to form guide openings for material entry and exit, and the tops of several of the inclined support blocks are rotatably connected to the bottom of the protective arc block.

[0011] Furthermore, the pushing assembly includes a first fixed trapezoidal block disposed on the left side of the pushing groove plate, and a second fixed trapezoidal block is fixedly installed above the first fixed trapezoidal block on the side closer to the pushing groove plate. Two protective cylinders are embedded in the opposite sides of the pushing groove plate and the first fixed trapezoidal block. Neodymium magnets are wrapped around the inner walls of several of the protective cylinders. A compression trapezoidal shell is slidably installed on the top of the second fixed trapezoidal block at the top of the two neodymium magnets. Several gravity balls are disposed on the inner walls of the two compression trapezoidal shells. A blocking plate is slidably installed on the side of the extrusion trapezoidal shell surface near the pushing groove plate, and fixing blocks are fixedly installed on both opposite sides of the blocking plate surface, and tension springs are fixedly installed at the bottom of the fixing blocks.

[0012] Furthermore, the material of several protective cylinders is 304 stainless steel. The neodymium magnets on the pushing groove plate and the neodymium magnets on the first fixed trapezoidal block are magnetically repelled. The extrusion trapezoidal shell and the second fixed trapezoidal block are slidably connected. The above-mentioned sliding connection method is the same as the sliding connection method between the protective arc groove block and the protective arc block, both of which adopt a sliding structure in which protrusions and concave parts interlock.

[0013] Furthermore, the lower ends of several of the tension springs are fixedly connected to the top of the second fixed trapezoidal block, the lower end of the barrier plate is set with a pointed tip, and the lower end of the barrier plate extends through to the bottom of the second fixed trapezoidal block and is embedded in the lower side of the inner wall of the protective arc groove block. The barrier plate is made of tungsten nickel copper material. The gravity balls inside the extrusion trapezoidal shell can accumulate as the tilt angle increases when the protective arc block tilts with the adjustment of the conveyor belt, and squeeze the blocking plate to move upward. Under the combined action of the repulsive force of the neodymium magnet and the tilting force, the protective arc block is pushed out, realizing lateral protection of the conveyor belt. When the conveyor belt returns to a horizontal state, the gravity balls spread out horizontally, and under the action of the tension spring and the reset damping spring, the blocking plate and the protective arc block are reset.

[0014] Furthermore, the reset assembly includes a storage slot formed on the right side of the inner wall of the T-shaped guide groove, and a reset damping spring is fixedly installed on one side of the inner wall of the storage slot, and the output end of the reset damping spring is fixedly connected to the surface of the T-shaped connecting block.

[0015] A conveying method using a slope conversion conveyor, the method comprising the following steps: Step 1: Start the double-output shaft right-angle reduction motor. The first sprocket, the second sprocket and the lifting chain belt drive the combined block to move up and down along the passage, so that the adjusting frame rises and falls relative to the support frame, thereby driving the conveyor belt to rotate around the fixed frame, so as to realize the continuous adjustment of the slope of the conveyor belt between horizontal and uphill postures. Step 2: During the conveyor belt tilting adjustment process, the protective arc trough block tilts synchronously with the conveyor belt. The gravity balls inside it accumulate to the lower side under the action of gravity, squeezing the blocking plate and making it move upward. At the same time, with the repulsive force generated by the neodymium magnets that are set up to repel each other, the protective arc block is pushed out of the protective arc trough block, forming a protective component that rises with the increase of the slope. Step 3: When the conveyor belt returns to a horizontal state, the gravity ball spreads out horizontally. Under the combined action of the tension spring and the reset damping spring, the barrier plate and the protective arc block automatically reset, and the protective components are lowered.

[0016] Compared with the prior art, the present invention provides a slope conversion conveyor and its conveying method, which has the following beneficial effects: 1. This device, by setting up continuously adjustable slope and slope conversion function, enables the conveying section to flexibly switch between horizontal and uphill sections. It can achieve a smooth transition between different slopes without the need for multiple equipment transfers. Compared with traditional fixed slope or cumbersome adjustment of conveying equipment, this application can make stepless adjustments according to the actual slope requirements on site, which significantly improves the adaptability and versatility of the conveying equipment to different sites and effectively solves the problem of frequent replacement or modification of equipment due to inconsistent site slopes.

[0017] 2. During the slope adjustment process, the posture change of the conveying section is stable and continuous, avoiding the material spillage or jamming caused by sudden angle changes in traditional slope structures. At the same time, the connection between the conveying section and the horizontal and high-level sections does not require additional transfer mechanisms, reducing material transfer links and lowering the risk of material blockage, thereby greatly improving the stability and reliability of the conveying process.

[0018] 3. As the tilt angle of the conveying section increases, the height of the protective structure can be increased in conjunction with the device, so that the material is more fully restrained during the climbing process. This design overcomes the safety hazards of material rolling or sliding when the tilt angle of traditional conveyors increases, and realizes the effect of automatic enhancement of protection capability with slope. Without adding extra operation or sensors, it effectively ensures the safety of conveyed materials. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 14 The slope conversion conveyor in this embodiment includes a fixed frame 1 and a support frame 2 disposed on one side of the fixed frame 1. A double-output shaft right-angle geared motor 3 is fixedly installed on the top of the support frame 2. The two output ends of the double-output shaft right-angle geared motor 3 are rotatably connected to the left and right sides of the top of the support frame 2 through a rotating shaft assembly, so that the output ends of the double-output shaft right-angle geared motor 3 can rotate freely relative to the top of the support frame 2. A first sprocket 4 is fixedly installed on each of the two output ends. A protective cover 5 is provided on each side inside the support frame 2. A second sprocket 6 is rotatably installed on the lower side inside each protective cover 5. A lifting chain belt 7 is meshed between the corresponding first sprocket 4 and second sprocket 6. The upper part of the protective cover 5 extends upward to above the top surface of the support frame 2, completely covering the first sprocket 4 to prevent foreign objects from entering the sprocket meshing area. Two protective covers 5 each have a passage opening 8 on their opposite sides. The passage opening 8 is a long strip-shaped through hole extending vertically. Two combination blocks 9 are fixedly installed on one side of the surface of each lifting chain 7. The two corresponding combination blocks 9 pass through the corresponding passage opening 8 and extend to the outer surface of the support frame 2. The part of the combination block 9 located outside the protective cover 5 is fixedly installed with an adjustment frame 10. By moving the combination block 9 up and down along the passage opening 8, the adjustment frame 10 can be adjusted vertically relative to the support frame 2. This lifting effect is within the passage opening 8. The lowest point of the inner wall of the passage opening 8 can ensure the horizontal state of the protective component 12. Therefore, the protective component 12 of this application will only start to operate after the whole is lifted. When the protective component 12 descends to the lowest point within the passage opening 8, the protective component 12 is in a horizontal state. Two adjusting frames 10 and fixed frame 1 are rotatably mounted together with two conveyor belts 11. Both conveyor belts 11 are multi-row parallel chain belt structures. When the adjusting frames 10 move up and down, the conveyor belts 11 can rotate around the fixed frame 1, thereby adjusting the slope of the conveyor belts 11. Protective components 12 are provided on both the front and rear sides of the surfaces of the two conveyor belts 11. Each protective component 12 includes a protective arc groove block 1201 fixedly installed on one side of the surface of the conveyor belt 11. The protective arc groove block 1201 is an arc-shaped groove plate structure, with its two ends raised to the sides relative to the surface of the conveyor belt 11 to form guide openings for material entry and exit. A protective arc block 1202 is slidably installed on the inner wall of the protective arc groove block 1201. Two T-shaped guide grooves 1203 are opened on the lower side of the inner wall of the protective arc groove block 1201. A T-shaped connecting block 1204 is slidably installed on the inner wall of each T-shaped guide groove 1203. A push trough plate 1205 is fixedly installed on the top of the two T-shaped connecting blocks 1204. Several inclined support blocks 1206 are rotatably installed on the inner wall of the push trough plate 1205. The top of each inclined support block 1206 is rotatably connected to the bottom of the protective arc block 1202. A pushing assembly 13 is provided on the left side of the pushing groove plate 1205. The pushing assembly 13 includes a first fixed trapezoidal block 1301 located on the left side of the pushing groove plate 1205. A second fixed trapezoidal block 1302 is fixedly installed on the upper side of the first fixed trapezoidal block 1301 near the pushing groove plate 1205. Two protective cylinders 1303 are embedded in the opposite sides of the pushing groove plate 1205 and the first fixed trapezoidal block 1301. The protective cylinders 1303 are made of 304 stainless steel. The inner wall of each protective cylinder 1303 is wrapped with neodymium magnets 1304. The neodymium magnets 1304 on the pushing groove plate 1205 and the neodymium magnets 1304 on the first fixed trapezoidal block 1301 are magnetically repelled. Two extruded trapezoidal shells 1305 are slidably installed on the top of the second fixed trapezoidal block 1302. The sliding connection adopts a sliding method in which the protrusions and concave parts interlock. Each extruded trapezoidal shell 1305 has several gravity balls 1306 on its inner wall. A blocking plate 1307 is slidably installed on the side of the extruded trapezoidal shell 1305 near the pushing groove plate 1205. The blocking plate 1307 is made of tungsten nickel copper material. Its lower end is pointed and extends through to the bottom of the second fixed trapezoidal block 1302 and is engaged with the lower side of the inner wall of the protective arc groove block 1201. Fixing blocks 1308 are fixedly installed on both opposite sides of the blocking plate 1307. A tension spring 1309 is fixedly installed at the bottom of the fixing block 1308. The lower end of the tension spring 1309 is fixedly connected to the top of the second fixed trapezoidal block 1302. A reset assembly 14 is provided on the right side of the inner wall of the two T-shaped guide grooves 1203. The reset assembly 14 includes a storage groove 1401 opened on the right side of the inner wall of the T-shaped guide groove 1203. A reset damping spring 1402 is fixedly installed on one side of the inner wall of the storage groove 1401. The output end of the reset damping spring 1402 is fixedly connected to the surface of the T-shaped connecting block 1204.

[0023] A conveying method using a slope conversion conveyor, employing the aforementioned device, includes the following steps: Step 1: Slope Adjustment Start the double-output shaft right-angle reduction motor 3, which drives the combined block 9 to move up and down along the passage 8 through the first sprocket 4, the second sprocket 6 and the lifting chain belt 7, thereby driving the conveyor belt 11 to rotate around the fixed frame 1, so as to realize the continuous adjustment of the slope of the conveyor belt 11 between horizontal and uphill postures. Step 2: Lateral protection raised During the tilt adjustment of the conveyor belt 11, the protective arc trough block 1201 tilts synchronously with the conveyor belt 11. The gravity ball 1306 inside it accumulates to the lower side under the action of gravity, squeezing the blocking plate 1307 to move upward. At the same time, the repulsive force generated by the neodymium magnet 1304 arranged in opposition assists in moving and pushing the trough plate 1205. The trough plate 1205 pushes the protective arc block 1202 out of the protective arc trough block 1201 through the inclined support block 1206, forming the protective component 12 that rises with the increase of the slope. Step 3: Lateral protection reset When the conveyor belt 11 returns to a horizontal state, the gravity ball 1306 unfolds horizontally and no longer presses against the barrier plate 1307. Under the combined action of the tension spring 1309 and the reset damping spring 1402, the barrier plate 1307 and the protective arc block 1202 automatically reset, and the protective assembly 12 lowers.

[0024] The working principle of the above-described device embodiment is as follows: When the device is in use, after the dual-output shaft right-angle geared motor 3 starts, its two output ends rotate synchronously, driving the first sprocket 4 to rotate. The first sprocket 4 drives the second sprocket 6 to rotate through the lifting chain belt 7. During the movement of the lifting chain belt 7, the assembly block 9 fixed on its surface moves accordingly. Since the assembly block 9 passes through the elongated through-hole 8 on the support frame 2 and is fixedly connected to the adjusting frame 10, the movement direction of the assembly block 9 is restricted to the vertical direction along the through-hole 8. When the assembly block 9 rises or falls, the conveyor belt 11 is rotatably installed between the adjusting frame 10 and the fixed frame 1. The lifting and lowering movement of the adjusting frame 10 forces the conveyor belt 11 to rotate around the hinge point of the fixed frame 1, thereby changing the position of the conveyor belt 11. The tilt angle of 1 can be continuously adjusted between horizontal and uphill slopes by controlling the forward and reverse rotation and rotation amount of the double-output shaft right-angle reduction motor 3. This device is mainly for side protection when the conveyor belt 11 is lifted around the fixed frame 1. When the protective component 12 inside the device is lifted, the internal pushing component 13 will be squeezed and activated, thus ensuring the unfolding of the protective arc block 1202. When the protective component 12 falls back to the initial horizontal state, the pushing component 13 will reset. The protective component 12 of this device mainly rises and falls in the passage 8 through the combination block 9. The state of the protective component 12 falling is compared with the state after the protective component 12 has risen. When the conveyor belt 11 tilts, the protective arc trough block 1201 fixed to its side tilts accordingly. The protective arc trough block 1201 contains a compression trapezoidal shell 1305, which holds several gravity balls 1306. In the tilted state, the gravity balls 1306 roll and accumulate to the lower side under their own weight. The accumulated gravity balls 1306 generate a compressive force, pushing the barrier plate 1307 upwards. The barrier plate 1307 is made of tungsten-nickel-copper alloy, characterized by non-magnetism and high strength. It also pushes the trough plate 1205 against the neodymium magnet 130 on the first fixed trapezoidal block 1301. 4. The repulsive arrangement causes the pusher plate 1205 to move to the right, closer to the fixed frame 1. The pusher plate 1205 slides along the T-shaped guide groove 1203 through the T-shaped connecting block 1204. The inclined support block 1206 connected to its inner wall gradually stands upright, pushing the protective arc block 1202 upward from the protective arc groove block 1201. The greater the inclination angle of the conveyor belt 11, the more serious the accumulation of gravity balls 1306, the higher the barrier plate 1307 rises, and the greater the distance that the magnetic repulsive force moves the pusher plate 1205. As a result, the protective arc block 1202 rises higher, achieving lateral containment of the material. When the conveyor belt 11 returns to a horizontal position, the gravity ball 1306 loses its gravity component along the inclined plane and naturally rolls back and spreads out horizontally under the action of gravity, no longer squeezing the barrier plate 1307. The barrier plate 1307 resets downward under the pulling force of the tension spring 1309 and re-embeds into the lower side of the inner wall of the protective arc groove block 1201. At the same time, the reset damping spring 1402 pushes the T-shaped connecting block 1204 to move to the left, driving the pusher plate 1205 to return to its original position. When the pusher plate 1205 returns to its original position, the inclined support block 1206 folds, and the protective arc block 1202 retracts into the protective arc groove block 1201 under its own weight or with slight assistance, reducing the lateral protection height.

[0025] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.

A conveying method for a slope conversion conveyor, characterized in that: The slope conversion conveyor described in claim 6, wherein the conveying method of the slope conversion conveyor includes the following steps: Step 1: Start the double-output shaft right-angle reduction motor (3), and drive the combination block (9) to move up and down along the passage (8) through the first sprocket (4), the second sprocket (6) and the lifting chain (7), so that the adjusting frame (10) rises and falls relative to the support frame (2), thereby driving the conveyor belt (11) to rotate around the fixed frame (1), so as to realize the continuous adjustment of the slope of the conveyor belt (11) between horizontal and uphill / downhill postures; Step 2: During the tilt adjustment of the conveyor belt (11), the protective arc groove block (1201) tilts synchronously with the conveyor belt (11). The gravity ball (1306) inside it accumulates to the lower side under the action of gravity, squeezing the blocking plate (1307) to make it move upward. At the same time, with the repulsive force generated by the neodymium magnet (1304) set in a repulsive manner, the protective arc block (1202) is pushed out from the protective arc groove block (1201) to form a protective component (12) that rises with the increase of the slope. Step 3: When the conveyor belt (11) returns to a horizontal state, the gravity ball (1306) unfolds horizontally. Under the combined action of the tension spring (1309) and the reset damping spring (1402), the barrier plate (1307) and the protective arc block (1202) automatically reset, and the protective component (12) is lowered.
