Description

Technical Field

[0001] This invention relates to the field of conveying device technology, specifically to a material conveying device that is easy to handle. Background Technology

[0002] Conveying devices are widely used in material handling, logistics and transportation in industrial production. The main components of a conveyor belt include the belt body, drive unit, tensioning device and support device. The belt body is usually made of high-strength and wear-resistant materials, such as rubber, polymer or metal. The drive unit is responsible for driving the conveyor belt.

[0003] Existing conveyor belts use a fixed frame structure. Due to their long length, they require frequent handling when materials are piled up in unpredictable locations, making them inconvenient to use. Ordinary inclined conveyor belts also have a fixed structure. There are also height-adjustable conveyor belts on the market that can transport construction materials in buildings of different heights, but they still have handling problems and need to be folded to reduce volume. There are foldable conveyor equipment on the market, but they can only be folded once, which creates a contradiction between conveying length, height and handling volume. If the conveying distance is long and the conveying height is high, the space occupied after folding is still very large. There is still a gap in the market for conveyor equipment that can convey long distances and have a small volume after folding. Summary of the Invention

By combining the lifting device and the auxiliary frame, the adjustable lifting action of the movable frame group is realized, reducing the dispersion area of ​​the stacked material; 5. The conveyor belt shape is defined by the tension adjustment structure and the pressure position structure, making the conveying process more stable. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Combined with appendix Figure 1 Appendix Figure 2Appendix Figure 3 Appendix Figure 4 and attached Figure 7 As shown, the system includes a conveying structure 1 and a driving structure 37. The conveying structure 1 includes a conveyor belt 2 driven by the driving structure 37, a movable frame assembly 3, a guide plate 4, and a roller assembly 5. The movable frame assembly 3 includes a front frame 31, a first folding frame 32, a second folding frame 33, a connecting frame 34, and a rear frame 35 that are hinged in sequence. The movable frame assembly 3 has a hinge platform 36 that rotates at the hinge point. The roller assembly 5 rotates and cooperates with the hinge platform 36 and the conveyor belt 2. The adjacent frames of the movable frame assembly 3 are arranged at an obtuse angle in the flattened state. The guide plate 4 is located inside the movable frame assembly 3 to support the conveyor belt 2, so that the upper surface of the conveyor belt 2 is horizontal in the flattened state.

[0033] Combined with appendix Figure 1 Appendix Figure 6 Appendix Figure 7 and attached Figure 15 As shown, the front frame 31, folding frame one 32, folding frame two 33, connecting frame 34 and rear frame 35 are provided with limiting inclined platforms 316 on one side of the hinge. The adjacent limiting inclined platforms 316 contact and cooperate to make the corresponding frame bodies form an obtuse angle. The inner side of the supporting column 61 is provided with a load-bearing platform 612. The outer side of the folding frame one 32 is provided with a swivel bearing platform 322 that rotatably cooperates with the load-bearing platform 612. The outer side of the front frame 31, folding frame two 33 and connecting frame 34 is provided with a load-bearing locking platform one 312 that is snapped into the load-bearing platform 612. The outer side of the rear frame 35 is provided with a load-bearing locking platform two 353 that is snapped into the load-bearing platform 612, and the bottom of the load-bearing locking platform two 353 is bolted to a fixing plate 38. The connected fixing plate 38 and load-bearing locking platform two 353 are rotatably cooperated with the load-bearing platform 612.

[0034] Working principle of movable frame group 3: Five frames are hinged adjacently with adjacent hinge points rotating in opposite directions. The front frame 31 is used for low-position feeding. Folding frame one 32 and folding frame two 33 form a group, and multiple groups can be set. In the flattened state, folding frame one 32, folding frame two 33 and connecting frame 34 are guided by guide plate 4 to make the upper conveyor belt 2 horizontal. In the lifted state, they are connected to the three through auxiliary frame 8, so that the angle of folding frame one 32, folding frame two 33 and connecting frame 34 is fixed, and the whole group rotates around the axis of the rotating bearing platform 322. The rear frame 35 is lifted in conjunction with the lifting device 7, and remains horizontal during the lifting process. The five frames In the exhibit state, the frame is folded by the folding drive structure 6. The five supports are folded by the rotating bearing platform 322 and the load-bearing platform 353 connected to the fixed plate 38 as fixed fulcrums. During the folding process, except for the front frame 31, the other frames are folded automatically. The front frame 31 needs to be manually lifted in advance. Then, the front frame 31 is lifted by the sliding cooperation between the load-bearing platform 612 and the bottom of the side plate 311. During the flattening process, the load-bearing platform 312 on the folding frame 33 and the connecting frame 34 automatically falls onto the corresponding load-bearing platform 612. The load-bearing platform 312 of the front frame 31 is manually locked onto the load-bearing platform 612.

[0035] Combined with appendix Figure 4 Appendix Figure 8 Appendix Figure 9 and attached Figure 11 As shown, the front frame 31 includes symmetrically arranged side plates 311. A functional frame 314 is connected below the side plates 311. The functional frame 314 includes a toolbox 3141 and a motor box 3142. The drive structure 37 includes a motor 371 located inside the motor box 3142. A sprocket 372 is provided at the output end of the motor 371. The roller group 5 includes rollers 51 and 52 of different sizes. Roller 51 is rotatably located at the hinge platform 36 at the front end of the front frame 31, the front end of the folding frame 33, and the front and rear ends of the rear frame 35. Roller 52 is rotatably located at the hinge platform 36 at the front end of the folding frame 32 and the front end of the connecting frame 34. A sprocket 511 is provided on one side of roller 51 at the front end of the front frame 31. The sprocket 372 and sprocket 511 are driven by a chain 373.

[0036] Working principle of drive structure 37: Motor 371 drives sprocket 1 372 to rotate, and through chain 373, sprocket 2 511 rotates, which drives roller 1 51 at the front frame 31 to rotate as the drive shaft, driving the conveyor belt 2 to rotate. The conveyor belt 2 cooperates with each roller 1 51 and roller 2 52 to carry out the conveying transmission. During this process, the conveyor belt 2 is guided by guide wheel 2 45 and guide wheel 1 354 to avoid collision with the rear frame 35, and is tightened by fixed roller 3151 and moving roller 3152.

[0037] Combined with appendix Figure 5 Appendix Figure 8 and attached Figure 9 As shown, a tension adjustment structure 315 is provided below the front frame 31. The tension adjustment structure 315 includes a fixed roller 3151, a movable roller 3152, an adjustment platform 3155, and a fixed platform 3153 connected to the bottom of the side plate 311. The fixed roller 3151 and the movable roller 3152 are rotatably engaged with the adjustment platforms 3155 on both sides. The adjustment platform 3155 and the fixed platform 3153 are rotatably engaged with the fixed roller 3151. An arc-shaped groove 3154 is provided on the front side of the fixed platform 3153. An adjustment block 3156 is provided on the outer side of the adjustment platform 3155, which is slidably engaged with the arc-shaped groove 3154. An arc-shaped spring 3157 connected to the arc-shaped groove 3154 is provided on the rear side of the adjustment block 3156. The conveyor belt 2 passes over the fixed roller 3151 and then passes over the movable roller 3152 in the opposite direction.

[0038] Working principle of tension adjustment structure 315: In the three different states of folding, flattening and lifting of the movable frame group 3, although the latter two are kept in contact with the conveyor belt 2 and the rotating rollers 51 and 52 by the pressure roller 3135, guide roller 45 and guide roller 354, the tension of the conveyor belt 2 will be different when the front frame 31 and the folding frame 32, and the connecting frame 34 and the rear frame 35 rotate relative to each other. During the folding to flattening process, the conveyor belt 2 needs to be tightened in time. When the conveyor belt 2 is relatively loose, the arc spring 3157 pushes the adjusting block 3156, which drives the fixed platform 3153 to rotate, changing the position of the moving roller 3152, increasing the length of the conveyor belt 2 at the tension adjustment structure 315, and thus tightening the conveyor belt 2. When the conveyor belt 2 is relatively tight, the conveyor belt 2 will pull the moving roller 3152 to move in the opposite direction, compressing the arc spring 3157, reducing the length of the conveyor belt 2 at the tension adjustment structure 315, and thus loosening the conveyor belt 2.

[0039] Combined with appendix Figure 3 Appendix Figure 8 and attached Figure 10 As shown, the side plate 311 is provided with a pressing structure 313. The pressing structure 313 includes a fixing frame 3131. The front side of the fixing frame 3131 is provided with an extension rod 3132. The front side of the extension rod 3132 is provided with an adjusting rod 3133. The rear end of the adjusting rod 3133 is rotatably provided with a pressure roller 3135 that contacts the conveyor belt 2. One side of the adjusting rod 3133 is provided with an adjusting block 3134 that slides with the groove on the front side of the extension rod 3132. One side of the adjusting block 3134 is provided with an adjusting spring 3136 that is connected to the groove on the extension rod 3132. The fixing frame 3131 is provided with a slanted guard plate 3137 in front of the adjusting rod 3133.

[0040] Working principle of pressure structure 313: During the lifting process, the position angle of the front frame 31 remains unchanged, and the folding frame 32 rotates, causing the conveyor belt 2 on both to move away from the guide table 43 and out of the adjustment range of the tension adjustment structure 315. It is also impossible to guarantee the stability of the conveyor. The pressure roller 3135 presses the conveyor belt 2 onto the rotating roller 52, so that the conveyor belt 2 is in contact with the guide table 43. During folding, the pressure roller 3135 will contact the guide plate 4 on the folding frame 32, preventing the folding process. Through the setting of the adjustment block 3134 and the adjustment spring 3136, after the guide plate 4 contacts the pressure roller 3135, the pressure roller 3135 moves backward, making room for folding. The pressure roller 3135 can move back and forth, which to a certain extent assists the tension adjustment structure 315 in realizing the tension adjustment and judgment of the conveyor belt 2 during lifting.

[0041] Combined with appendix Figure 4 Appendix Figure 5 and attached Figure 14 As shown, the guide plate 4 includes a connecting platform 41 and a crossbeam 42. The two ends of the crossbeam 42 are connected to the connecting platform 41. The connecting platform 41 is connected to each frame of the movable frame assembly 3. A plurality of guide platforms 43 are evenly provided on the crossbeam 42. A clearance groove 44 is provided between adjacent guide platforms 43. The guide platforms 43 on adjacent guide plates 4 are staggered. The guide platform 43 is inserted into the clearance groove 44 of another guide plate 4. The guide plate 4 on the rear end frame 35 is provided with a second guide wheel 45 that rotates behind the guide platform 43.

[0042] Working principle of guide plate 4: In order to simplify the folding of the movable frame group 3 with the folding drive structure 6, each frame of the movable frame group 3 is tilted when it is flat. The reverse tilted guide plate 43 is in a horizontal state at this time, ensuring the horizontal transport of the upper conveyor belt 2. When folding, the adjacent misaligned guide plates 43 are inserted into the avoidance groove 44 to avoid the protruding guide plates 43 from colliding and affecting the folding space.

[0043] Combined with appendix Figure 2 Appendix Figure 3 and attached Figure 15 As shown, the conveying structure 1 is provided with folding drive structures 6 on both sides. The folding drive structures 6 drive the movable frame group 3 to fold. The folding drive structure 6 includes a support column 61 and a scissor frame 62. In the flattened state, each frame of the movable frame group 3 is supported by the support column 61. The lower hinge point of the scissor frame 62 is hinged to the outer boss of the support column 61. A limiting block 63 is slidably provided in the limiting groove 614 on the outer side of the support column 61. The upper hinge point of the scissor frame 62 is hinged to the limiting block 63. A support platform 613 is provided on the inner side of the support column 61 below the connecting frame 34 and the rear frame 35. An electric push rod 64 is provided between the two support platforms 613. A roller 611 is rotatably provided at the bottom of the support column 61.

[0044] Working principle of folding drive structure 6: When unfolded, electric push rod 64 pushes two support columns 61 to move in opposite directions. The scissor frame 62 makes multiple support columns 61 move synchronously and at the same speed, causing the rotating bearing platform 322 and the load-bearing clamp platform 353 to move away from each other, causing each frame of the movable frame group 3 to rotate towards the unfolding trend. After the adjacent limiting inclined platform 316 contacts, the angle of each frame of the movable frame group 3 is fixed. At this time, the load-bearing clamp platform 312 falls on the support platform 613, so that the weight of each frame of the movable frame group 3 is borne by multiple support columns 61. When the movable frame group 3 is in the raised state, the support columns 61 and the scissor frame 62 act as bottom enclosures.

[0045] Combined with appendix Figure 2 Appendix Figure 12 Appendix Figure 13 and attached Figure 16 As shown, the rear end frame 35 is provided with a lifting device 7 at its bottom. The lifting device 7 tilts the folding frame 32, folding frame 33 and connecting frame 34 by horizontally lifting the rear end frame 35. The lifting device 7 includes a base plate 71 and a lifting plate 75. Rollers 72 are rotatably provided below the base plate 71. An electric push rod 73 is connected between the base plate 71 and the lifting plate 75. A positioning cylinder 74 is provided on the base plate 71. A positioning column 751 that slides with the positioning cylinder 74 is provided at the bottom of the lifting plate 75. The rear end frame 35 includes a side plate 351. A parallel plate 352 is connected between the bottoms of the side plates 351. Multiple guide wheels 354 are rotatably provided on the front side of the parallel plate 352. The conveyor belt 2 passes through the gap between the top of the parallel plate 352 and the guide plate 4. A positioning groove 355 is provided at the bottom of the parallel plate 352. A positioning platform 752 that engages with the positioning groove 355 is provided at the top of the lifting plate 75.

[0046] Working principle of lifting device 7: In the flattened and folded state, lifting device 7 is not connected to movable frame group 3. When lifting is required, lifting device 7 is pushed to the bottom of parallel plate 352. The lifting plate 75 is pushed up by electric push rod 2 73, so that positioning platform 752 is locked into positioning slot platform 355, realizing the connection between lifting plate 75 and parallel plate 352, ensuring that rear frame 35 rises horizontally. Since folding frame 1 32, folding frame 2 33 and connecting frame 34 rotate around the axis of swivel bearing platform 322, rear frame 35 moves towards front frame 31 at the same time during the rising process, and lifting device 7 moves with lifting plate 75.

[0047] Combined with appendix Figure 2 Appendix Figure 6 and attached Figure 17As shown, the movable frame assembly 3 is equipped with an auxiliary frame 8. The auxiliary frame 8, in conjunction with the lifting device 7, enables the movable frame assembly 3 to be raised and lowered. The auxiliary frame 8 is connected to the first folding frame 32, the second folding frame 33, and the connecting frame 34 to fix their connection angle. The auxiliary frame 8 includes a longitudinal beam 81. The bottom of the longitudinal beam 81 is provided with multiple insertion platforms 83. The first folding frame 32, the second folding frame 33, and the connecting frame 34 all include symmetrically arranged side plates 321. The top of each side plate 321 is provided with a slot 323 that engages with the insertion platform 83. A straight guard plate 82 is provided on one side of the longitudinal beam 81.

[0048] Working principle of auxiliary frame 8: Since folding frame one 32, folding frame two 33 and connecting frame 34 are only connected by hinges, when lifting, folding frame two 33 and connecting frame 34 will tend to fold. The auxiliary frame 8 is connected to folding frame one 32, folding frame two 33 and connecting frame 34 to fix the three. The straight guard plate 82 prevents the conveying parts from falling.

[0049] In practical implementation, the device is normally folded. During use, the folding drive structure 6 flattens the movable frame group 3 and provides support for it. When lifting is required, the middle section of the movable frame group 3 is lifted by the lifting device 7 and the auxiliary frame 8 to transport items to a higher position. During this process, the tension adjustment structure 315 and the pressing structure 313 ensure the normal shape of the conveyor belt 2. The drive structure 37 drives the conveyor belt 2 to operate. When a folding frame is added to the movable frame group 3, the lifting device 7 can be replaced with a scissor lift to increase the lifting height.

[0050] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
