[0015] Working principle: when in use, place the conveyor belt 1 directly against the vehicle loaded with materials, and then start the servo motor, so that the servo motor can drive the conveyor belt 1 to rotate through the transmission rod 1 with the cooperation of the rear rod inside the conveyor belt 1. At this time, the material can be placed on the surface of the conveyor belt 1 and brought to the conveyor belt 2 by the conveyor belt 1. At the same time, when the transmission rod 1 rotates, it can also drive the driving wheel to rotate, and then the driven wheel meshing with the driving wheel can drive the connecting rod to rotate synchronously along the hole pre-opened on the surface of the support frame 1. Furthermore, since one end of the movable frame is connected to the connecting rod, and the other end is connected to the U-shaped frame through the convex column and the bevel gear 1, the movable frame can swing back and forth when the connecting rod rotates continuously, and the convex column can move horizontally along the movable frame while moving back and forth with the movable frame, and With the cooperation of the limit rod 1 and the U-shaped frame, the bevel gear 1 can be driven to rotate in one direction, and the bevel gear 2 meshing with the bevel gear 1 can transmit the rotation to the transmission rod 2. Similarly, with the cooperation of the front rod inside the conveyor belt 2, the conveyor belt 2 can be driven by the transmission rod 2 to continuously move inside the support frame 2, so as to continuously transport the materials transferred from the conveyor belt 1 to the conveyor belt 2 forward, and because the bevel gear 1 and the bevel gear 2 are always meshed due to the limit rod 1 and the rotating frame, when the bevel gear 2 rotates horizontally around the limit rod 1 to a certain angle with the connecting ring and the support frame 2, the rotation output by the bevel gear 1 can still be transmitted to the conveyor belt 2 by the transmission rod 2. In summary, the angle between the conveyor belt 1 and the conveyor belt 2 can be adjusted within a certain range while driving the normal movement of the conveyor belt 1 and the conveyor belt 2. , so as to be suitable for the actual needs of stacking materials in different positions, improve the freedom and convenience of use, avoid the situation that when conveyor belt 1 is used alone, the materials are restricted by the conveying direction, resulting in the need for staff to carry them in other directions outside the conveying direction. Both conveyor belt 1 and conveyor belt 2 are driven by servo motors, which improves energy utilization and avoids the need to use double wires to supply conveyor belt 1 and conveyor belt 2 respectively. In addition, the use of bevel gear 1 and bevel gear 2 can make the transmission and steering stable without obvious rigid impact. As the roller unlocked at the bottom of support frame 2 drives support frame 2, conveyor belt 2, bevel gear 2, U-shaped frame, etc. to rotate, the rotating rod frame 2 connected to support frame 2 can also rotate relative to the rotating rod frame 1, and then the trapezoidal plate 1 and trapezoidal plate 2 can be used respectively. The material moving from conveyor belt one to conveyor belt two is guided to prevent the material from falling to the ground from the non-overlapping area due to the inability of conveyor belt one and conveyor belt two to completely overlap in the vertical direction after the direction of conveyor belt two is changed, thereby achieving the guidance and auxiliary needs of conveyor belt two after rotating at different angles. At the same time, spring one can cooperate with the guide rod to apply a horizontal thrust to arc plate one, thereby adjusting the position of the material when it is transferred to conveyor belt two to a certain extent, and the arc plates one on both sides can also offset part of the impact force when the material slides down along rotating rod frame one and rotating rod frame two. In addition, spring two can be cooperated to push the discs on both sides closer to each other, thereby causing the evenly distributed rotating plates to rotate and applying a thrust to each arc push plate to move toward the outside of hollow cylinder two.Further, the evenly distributed arc-shaped push plates can be used to support and tension the conveyor belt 2 from the inside, so as to work together with the arc-shaped plate 1 and the spring 1 to maintain the normal operation of the conveyor belt 2. At the same time, the tensioning mechanism can also be added to the middle area of ​​the conveyor belt 1 according to the needs.

[0016] The present invention provides an automatic material conveying device with intelligent self-adaptive adjustment, which has the following beneficial effects.

[0017] 1. The present invention can adjust the direction of the conveyor belt 2 while driving the conveyor belt 1 and the conveyor belt 2 to move through the setting of the steering mechanism, so as to facilitate the stacking of the conveyed materials in different directions, reduce the labor intensity of the staff, and be more suitable for actual needs. The cooperation of the bevel gear 1 and the bevel gear 2 can avoid obvious impact on the components during the transmission and steering process, thereby ensuring the stability during transportation. In addition, the servo motor can drive the conveyor belt 1 and the conveyor belt 2 at the same time, thereby improving the energy utilization rate, complying with the concept of green production, reducing the number of related power supply wires, and reducing the probability of damaging the wires when moving the support frame 2.

[0018] 2. The present invention can adjust and guide the material automatically when it moves from conveyor belt one to conveyor belt two by setting a guiding mechanism, so as to prevent the material from falling directly from a certain range of non-overlapping area between conveyor belt two and conveyor belt one after conveyor belt two turns, thereby achieving the effect of maintaining safe transfer of materials. In addition, the impact force when the material contacts conveyor belt two can be reduced to a certain extent.

[0019] 3. The present invention can tension the conveyor belt 2 from inside by setting a tensioning mechanism to prevent the transmission rod 2 from being unable to normally drive the relaxed conveyor belt 2 to rotate, and can cooperate with the guide mechanism to offset part of the impact force on the conveyor belt 2.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0023] Please see attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 6 The embodiment of the present invention provides an intelligent adaptively adjustable automatic material conveying device, comprising a support frame 1, a steering mechanism 2 is arranged inside the support frame 1, a guiding mechanism 3 is arranged at the front end of the support frame 1, and a tensioning mechanism 4 is arranged inside the steering mechanism 2; The steering mechanism 2 includes a transmission rod 201, two ends of which are rotatably connected to the front parts of both sides of the support frame 1, a conveyor belt 202 is arranged on the outside of the transmission rod 201, a servo motor 203 is fixedly connected to the front part of one side of the support frame 1, the output end of the servo motor 203 passes through the support frame 1 and is fixedly connected to one end of the transmission rod 201, a driving wheel 204 is fixedly connected to the outside of one side of the transmission rod 201, a driven wheel 205 is meshed with the rear part of the driving wheel 204, a connecting rod 206 is fixedly connected to the side of the driven wheel 205 away from the conveyor belt 202, and a movable frame 207 is fixedly connected to the end of the connecting rod 206 away from the driven wheel 205. A boss 208 is slidably connected to the front of the frame 207, and a bevel gear 209 is rotatably connected to the bottom end of the boss 208. The bottom end of the bevel gear 209 is rotatably connected to a limit rod 210. The outer side of the limit rod 210 is rotatably connected to a rotating frame 211. The outer side of the rotating frame 211 is rotatably connected to a bevel gear 212. The upper part of the bevel gear 212 is meshed with the bottom of the bevel gear 209. A support frame 213 is provided at the lower front side of the support frame 1. A transmission rod 214 is rotatably connected to the rear part of the support frame 213. A conveyor belt 215 is provided on the outer side of the transmission rod 214. One end of the transmission rod 214 is fixedly connected to the end of the bevel gear 212 away from the rotating frame 211.

[0024] The transmission rod 201 can be supported by the support frame 1, and then the transmission rod 201 can cooperate with the rod at the rear of the conveyor belt 202 under the drive of the servo motor 203 to drive the conveyor belt 202 to rotate forward. At the same time, the driving wheel 204 connected to the transmission rod 201 can also transmit the rotation output by the servo motor 203 to the connecting rod 206 at the eccentric position of its surface through the driven wheel 205. Since the movable frame 207 is connected to the connecting rod 206 and the boss 208 at the same time, the movable frame 207 can swing to the boss 208 applies a thrust to move in the forward and backward directions. Furthermore, since the boss 208 can rotate around the axis of the boss 208 itself at the eccentric position on the upper surface of the bevel gear 1 209, the relatively flexible boss 208 can move forward as a whole with the movable frame 207 when pushed by the movable frame 207, and can also move relatively horizontally along the movable frame 207 to drive the bevel gear 1 209 to rotate in one direction. At this time, the bevel gear 212 that is restricted by the limited position rod 1 210 and the rotating frame 211 and keeps meshing with the bevel gear 1 209 can transmit the rotation to the transmission The second rod 214 is provided, so that the conveyor belt 215 is driven to rotate continuously inside the support frame 213 through friction under the cooperation of the front rod in the transmission rod 214. In summary, the conveyor belt 1 202 and the conveyor belt 215 can be rotated simultaneously under the cooperation of the servo motor 203, the transmission rod 1 201, the transmission rod 214 and related components, so as to make full use of the power output of the servo motor 203, avoid the need for multiple power sources, and also reduce the number of power supply wires, thereby reducing the damage to the power supply wires when moving the support frame 213 in a limited space. The probability of a line is obtained, and the limit rod 1 210 and the rotating frame 211 can make the bevel gear 212 still keep meshing with the bevel gear 1 209 after rotating around the limit rod 1 210 along with the transmission rod 214, the support frame 213, etc., so that the direction of the conveyor belt 215 can be freely adjusted without affecting the normal rotation of the conveyor belt 1 202 and the conveyor belt 215, so as to actively adapt to the stacking requirements of materials in different directions. In addition, since the bevel gear 1 209 and the bevel gear 212 are always effectively meshed, the transmission stability is high and the rigid impact is small.

[0025] Please see attached Figure 3 and attached Figure 6 The driving wheel 204 is rotatably connected to the front part of the inner side of the support frame 1 on the outer side away from the conveyor belt 202, and the driven wheel 205 is rotatably connected to the inner side of the support frame 1 on the outer side away from the conveyor belt 202.

[0026] The driving wheel 204 and the driven wheel 205 can be limited respectively by the support frame 1, thereby ensuring that the driving wheel 204 and the driven wheel 205 will not be displaced during movement to prevent them from being disengaged from each other.

[0027] Please see attached Figure 5 and attached Figure 6The side of the movable frame 207 close to the support frame 1 is rotatably connected with an annular guide block 216, and the side of the annular guide block 216 away from the movable frame 207 is fixedly connected to the side of the support frame 1, and the annular guide block 216 is directly opposite to the driven wheel 205.

[0028] The movable frame 207 can be guided by the annular guide block 216 to ensure that the movable frame 207 does not move horizontally when it swings, thereby preventing the connection between the movable frame 207 and the connecting rod 206 from being broken by excessive force. At the same time, the annular guide block 216 is facing the driven wheel 205 to ensure that it does not interfere with the swing of the movable frame 207.

[0029] Please see attached Figure 6 The outer side of the bevel gear 212 away from the rotating frame 211 is rotatably connected with a connecting ring 217, and the end of the connecting ring 217 away from the bevel gear 212 is fixedly connected to the rear part of one side of the supporting frame 213.

[0030] The connecting ring 217 and the second support frame 213 can increase the distance between the first bevel gear 209 and the second support frame 213 while supporting the second bevel gear 212, thereby preventing the first bevel gear 209 from colliding with the second support frame 213 when rotating.

[0031] Please see attached Figure 2 and attached Figure 6 A U-shaped frame 218 is fixedly connected to the rear of one side of the support frame 213, the outer top of the bevel gear 209 is rotatably connected to the top of the U-shaped frame 218, and the bottom end of the limit rod 210 is rotatably connected to the bottom of the U-shaped frame 218.

[0032] The U-shaped frame 218 can be used to limit the helical gear 209 and the rotating frame 211 to prevent them from shaking and affecting normal transmission, and there is also a through hole at the top of the U-shaped frame 218 for the boss 208 to move.

[0033] Please see attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 The guiding mechanism 3 includes a rotating rod frame 301, the rear end of which is fixedly connected to the upper front end of the supporting frame 1, the top sides of the rotating rod frame 301 are fixedly connected with a trapezoidal plate 1 302, the bottom end of the rotating rod frame 301 is rotatably connected with a rotating rod frame 2 303, the top sides of the rotating rod frame 2 303 are fixedly connected with a trapezoidal plate 2 304, and the bottom sides of the rotating rod frame 2 303 are fixedly connected to the rear of the top of the supporting frame 2 213.

[0034] Through the relative rotation between the rotating rod frame 1 301 and the rotating rod frame 2 303, the roller at the bottom of the support frame 213 can be unlocked to drive the support frame 213 to rotate, so that the support frame 1 and the support frame 2 213 can still be connected through the rotating rod frame 1 301 and the rotating rod frame 2 303. Then, as the conveyor belt 215 rotates, when there is a non-overlapping area between the conveyor belt 2 215 and the conveyor belt 1 202 in the vertical direction, the self-adjustment of the rotating rod frame 1 301 and the rotating rod frame 2 303 can be used to actively block the area, and with the cooperation of the trapezoidal plate 1 302 and the trapezoidal plate 2 304, the materials can move along the conveyor belt 1 202, the rotating rod frame 1 301, the rotating rod frame 2 303, and the conveyor belt 2 215 in sequence to prevent the materials from falling to the ground and being damaged.

[0035] Please see attached Figure 5 A guide rod 305 runs through the inside of the trapezoidal plates 304 on both sides, and the ends of the guide rods 305 on both sides are fixedly connected to the arc-shaped plates 306 on the closer ends, and the arc-shaped plates 306 on both sides are fixedly connected to the sides away from each other with springs 307. The springs 307 on both sides are wound around the outside of the guide rods 305, and the ends of the springs 307 away from each other are fixedly connected to the closer sides of the trapezoidal plates 304.

[0036] The arc plate 1 306 can be limited by the guide rod 305 and the trapezoidal plate 2 304 to ensure that the arc plate 1 306 can only slide along the rotating rod frame 2 303, and then the spring 1 307 can be used to push the arc plates 1 306 on both sides to approach each other, so as to guide the material moving along the surface of the rotating rod frame 2 303 to a certain extent, so that the material can be in the middle area when moving to the surface of the conveyor belt 2 215, and the spring 1 307 and the arc plate 1 306 can also offset part of the impact force during the sliding of the material. In addition, the spring 1 307 is wrapped around the outside of the arc plate 1 306 to prevent them from interfering with each other during movement.

[0037] Please see attached Figure 7 L-shaped brackets 308 are fixedly connected to both sides of the front top of the support frame 1, and arc-shaped plates 309 are slidably connected to the bottom ends of the L-shaped brackets 308 on both sides, and multiple limit rods 2 310 are fixedly connected to the side away from the arc-shaped plates 2 309 on both sides, and hollow cylinders 1 311 are slidably connected to the outer sides of the multiple limit rods 2 310. The ends of the hollow cylinders 1 311 on both sides are fixedly connected to the side away from the inside of the L-shaped brackets 308 on both sides at the distant ends, and blocking rods 312 are slidably connected to the upper parts of the multiple limit rods 2 310, and the tops of the multiple blocking rods 312 pass through the hollow cylinder 1 311.

[0038] The L-shaped bracket 308 can provide support for the evenly distributed hollow cylinders 311, and the limiting rods 310 inside each hollow cylinder 311 can ensure that the arc plate 309 can only move horizontally. At the same time, the position of the arc plate 309 can be adjusted by cooperating with the blocking rod 312 moving along the hollow cylinder 311 and the evenly distributed holes inside each limiting rod 310, so as to adjust the position of materials of different sizes from both sides, so as to avoid obvious squeezing between the trapezoidal plates 1 302 and 2 304 when the materials are at the edge of the conveyor belt 202 and move along the rotating rod frame 1 301 and the rotating rod frame 2 303.

[0039] Please see attached Figure 4 and attached Figure 8 The tensioning mechanism 4 includes a hollow cylinder 401, and the outer sides of the multiple hollow cylinders 401 are all arranged in the middle of the conveyor belt 215. Both ends of the multiple hollow cylinders 401 are fixedly connected with springs 402, and the ends of the springs 402 on both sides are fixedly connected with discs 403, and the sides of the discs 403 on both sides are rotatably connected with multiple rotating plates 404. The multiple hollow cylinders 401 are slidably connected with multiple arc-shaped push plates 405, and the ends of the rotating plates 404 away from the discs 403 are rotatably connected to the two sides of the multiple arc-shaped push plates 405.

[0040] The conveyor belt 215 can be supported to a certain extent by each hollow cylinder 401 to prevent the upper surface of the conveyor belt 215 from being excessively concave when the material moves to the surface of the conveyor belt 215. At the same time, the spring 402 can push the discs 403 on both sides closer to each other, so that the evenly distributed rotating plates 404 can apply thrust to the arc-shaped push plates 405, and further the evenly distributed arc-shaped push plates 405 can be moved from the inside of the hollow cylinder 401 to the outside, thereby actively tensioning the hollow cylinder 401 to prevent the conveyor belt 215 from being deformed and relaxed and the transmission rod 214 from being unable to drive the conveyor belt 215 to rotate normally.

[0041] Please see attached Figure 8 , the interior of multiple hollow cylinders 214 are fixedly connected with limit rods 3 406, the middle of the disk 403 is slidably connected to the two sides of the outside of the multiple limit rods 3 406, multiple springs 214 are wound around the two sides of the outside of the limit rods 3 406, and the middle of both sides of the support frame 213 are fixedly connected with support plates 407, and the two ends of the hollow cylinder 214 are rotatably connected to the side close to the support plates 407 on both sides.

[0042] The disc 403 can be restricted by the limit rod three 406 to prevent the disc 403 from shaking during movement, thereby avoiding affecting the movement of each arc-shaped push plate 405, and the spring two 402 wrapped around the outer side of the arc-shaped push plate 405 can ensure that they do not interfere with each other during movement. In addition, the support plate 407 can be used to fix and support the evenly distributed hollow cylinder two 401.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
