[0002] Bidding and procurement refers to a process in which the purchaser, as the tenderer, first puts forward the conditions and requirements for procurement, invites numerous enterprises to participate in the bidding, and then the purchaser selects the trading object from them once according to the specified procedures and standards, and signs an agreement with the tenderer who offers the most favorable conditions; bidding and procurement is one of the most common methods in government procurement; bidding and procurement can be divided into competitive procurement and restricted tendering procurement; with the development of society, bidding and tendering in the current market are often carried out on a bidding and procurement platform, and bidding is carried out by swiping the bidding card.

[0003] In on-site bidding, first, it is necessary to identify personal identity information, and then submit the sorted bidding materials to the staff for review. In this process, when the number of bidders is large, the materials are prone to chaos, and it is also easy to cause loss or leakage, affecting the maintenance of the order at the bidding site. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a method and device for bidding and tendering management on a bidding and procurement platform to solve the problems raised in the above background technology. The structure of the present invention is novel. After the personal identity is identified by the device, the bidding materials are sent into the collection box. The materials of each bidder are isolated from each other to avoid chaos. The materials are stored in the collection box, which can avoid the problems of leakage and loss, and the position where the materials are arranged corresponds to the serial number of the personal identity identification, thus facilitating the staff to sort them out.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A bidding and procurement platform tendering and bidding management device, including an operation box, on the top of the operation box is fixed an installation frame, and on the top of the installation frame is fixed a display screen. On the top of the display screen is fixedly installed a camera, and inside the camera is an identification module. On the front top surface of the operation box is installed a keyboard. Inside the operation box are provided two sets of collection boxes, and the two sets of collection boxes are arranged side by side vertically. Inside the operation box at the bottom of the collection boxes is fixed a control box, and inside the collection boxes are equidistantly fixed partitions. On one side of the top of the operation box is opened a feeding slot. On the top of the operation box is provided a driving component, and the driving component includes a scale disk. On the top of the installation frame away from the feeding slot is fixed a scale disk, and on the surface of the scale disk are symmetrically fixed multiple labels around the center of the circle. On the top of the scale disk is rotatably installed a rotating plate. On the inner wall of the top of the operation box is provided a delivery frame, and between the delivery frame and the feeding slot is fixedly connected an extensible and foldable net. On one side surface of the operation box at the positions corresponding to the two collection boxes are installed electromagnetic doors, and on the inner wall of the other side of the operation box is provided a lifting component, and the lifting component includes a screw rod.

[0006] Further, on the inner walls of both sides of the operation box at the positions of the collection boxes are fixed sliding rails, and inside the sliding rails are slidably inserted mounting plates. The two sides of the collection boxes are locked and connected to the mounting plates by bolts. One end of the mounting plate and the sliding rail are fixedly connected with a second spring.

[0007] Further, the driving component further includes a disk. At the bottom of the installation frame opposite to the rotation center of the rotating plate is rotatably installed a disk, and the disk is fixedly connected to the rotating shaft of the rotating plate. At the eccentric position of the bottom of the disk is rotatably installed a first connecting rod through a rotating shaft, and the other end of the first connecting rod is rotatably connected to a second connecting rod through a rotating shaft.

[0008] Further, on the top of the delivery frame is fixed a sliding seat through multi-section telescopic plates. On the top of the operation box corresponding to the moving path of the sliding seat is opened a moving slot, and inside the moving slot is slidably connected a sliding block. The sliding block is fixedly connected to the sliding seat. On the top of the sliding seat is rotatably installed a shaft rod through a bearing, and the shaft rod is fixedly connected to the other end of the second connecting rod. At the bottom of the operation box at the position of the moving slot is fixed a sliding rod. The sliding seat is slidably sleeved on the sliding rod, and one end of the sliding rod is fixed with a fixed block. The fixed block is rotatably sleeved on the top of the screw rod.

[0009] Further, the lifting component further includes a vertical slot. On the inner wall of the operation box is opened a vertical slot, and both ends of the screw rod are rotatably installed inside the vertical slot through bearings, and the screw block slides along the vertical slot. The top of the screw rod passes through the operation box and is installed with a second transmission belt, and the other end pulley of the second transmission belt is installed at the bottom of the other end of the installation frame.

[0010] Further, a first transmission belt is installed on the top of the mounting frame. One pulley of the first transmission belt is fixedly connected to the pulley of the second transmission belt, and the other pulley of the first transmission belt is fixedly connected to the rotating shaft of the rotating plate.

[0011] Further, annular grooves are formed on both side surfaces of the operation box, and a cavity is arranged inside the annular grooves. A vertical rod is installed in the cavity of the operation box. A connecting plate is slidably sleeved on the surface of the vertical rod, and the connecting plate is fixedly connected to the feeding frame.

[0012] Further, a first spring is sleeved on the surface of the vertical rod, and the other end of the first spring is fixedly connected to the connecting plate. Sliding rails are fixedly arranged at the top and bottom of the cavity of the operation box, and the top and bottom of the vertical rod slide along the sliding rails.

[0013] Further, a connecting frame is fixedly installed at the bottom of the back of the mounting plate of the collection box, and a cylinder is fixedly arranged on the surface of the connecting frame. A flat plate is fixedly arranged on the surface of the screw block, and an inclined block is fixedly arranged at the bottom of the flat plate. The cylinder alternately slides in contact with the inclined plate and the flat plate.

[0014] A method for managing tendering and bidding on a tendering and procurement platform, the management method comprising the following steps: (1) The bidder inputs identity information and bid information through a keyboard and a display screen, and is monitored in real time by a camera and stored in a computer mainframe for identity recognition. (2) After the recognition is completed, the rotating plate is rotated once, and the rotating plate rotates to the next number. At the same time, the identity of the person is recognized and numbered. (3) The user can send the sorted tender materials into the feeding slot, and under the action of the driving component, the materials are stored in the partitions of the corresponding collection boxes in sequence. (4) After each layer of materials is full, the electromagnetic door is opened, and the staff takes out and sorts the material collection box, which corresponds to the order of the personnel identification numbers one by one.

[0015] Advantages of the present invention: Through the arrangement of the annular grooves and cavities on both sides of the operation box of the present invention, it is convenient for the vertical rod to move along the sliding rail. And there are horizontal openings at the positions corresponding to the tops of the two collection boxes in the annular grooves. These openings can facilitate the vertical rod to drive the connecting plate to move, thereby pulling the feeding frame to move horizontally, and sequentially aligning the feeding frame with each column on the collection box. When the vertical rod moves to the vertical direction of the annular groove, the connecting plate is pulled down by the elastic force of the first spring. At this time, the feeding frame will also descend to the top of the next collection box to continue filling the lower collection box with tender materials.

[0016] In the present invention, since the disk drives the first connecting rod to rotate, the movement of the second connecting rod is reciprocating. Therefore, the feeding frame can continue to move along the horizontal opening at the lower end to sequentially fill the lower collecting box with materials. During this process, when the connecting plate drives the feeding frame to descend, the telescopic folding net can be unfolded. At the same time, the multi-section telescopic plate connecting the sliding seat and the feeding frame will also extend to maintain connectivity. The annular groove is actually a C-shaped groove, which can allow the feeding frame to move horizontally twice and vertically in sequence to switch the position of material conveyance.

[0017] In the present invention, under the transmission connection of the first transmission belt and the second transmission belt, when the rotating plate rotates, the screw rod will also rotate. The screw block cooperates with the screw rod and moves downward along the vertical groove. At this time, the flat plate still contacts the cylinder to keep the collecting box in the front position, and receives and feeds the first batch of materials one by one between the corresponding partitions.

[0018] When the upper collecting box of the present invention is loaded, at this time, the flat plate just releases the extrusion on the cylinder. Through the elastic force of the second spring, the rotating plate slides along the slide rail, and the upper collecting box moves backward to give space for the feeding frame to move. At the same time, the electromagnetic door on the upper layer opens, which is convenient for the staff to separate the upper collecting box from the mounting plate and take out the stored materials inside. As the screw rod continues to rotate, the inclined plate first contacts the cylinder and pushes the cylinder outwards, corresponding the lower collecting box with the feeding frame again to perform the filling work of the lower collecting box.

[0019] In the present invention, the rotating plate drives the disk to rotate, and the first connecting rod and the second connecting rod cooperate. The second connecting rod pushes the slider to slide along the moving groove, thereby advancing the position of the feeding frame. The positions of each partition on the collecting box can be numbered in sequence, which is consistent with the identification number of the identity recognition, so that it is more convenient to correspond the identified personnel with the materials one by one, facilitating statistics and sorting.

[0020] Compared with the prior art, in the present invention, after the personal identity is recognized by the device, the tender materials are sent into the collecting box. The materials of each bidder are isolated from each other to avoid chaos. The materials are stored in the collecting box, which can avoid leakage and loss problems. And the arranged positions of the materials correspond to the serial numbers of the personal identity recognition, thus facilitating the staff to sort them out. BRIEF DESCRIPTION OF THE DRAWINGS

(4)After each layer of materials is full, the electromagnetic door is opened, and the staff takes out and sorts the material collection box, which corresponds one by one with the order of the personnel identification numbers.

[0025] A bidding and procurement platform bidding and tendering management device, including an operation box 1. A mounting frame 21 is fixed on the top of the operation box 1, and a display screen 11 is fixed on the top of the mounting frame 21. A camera 12 is fixedly installed on the top of the display screen 11, and an identification module is inside the camera 12. A keyboard 13 is installed on the front top surface of the operation box 1. Two collection boxes 5 are arranged inside the operation box 1 in parallel up and down. A control box 14 is fixed at the bottom of the collection box 5 inside the operation box 1, and partitions 52 are equidistantly fixed inside the collection box 5. A feeding slot 16 is opened on one side of the top of the operation box 1. A driving component 2 is arranged on the top of the operation box 1. The driving component 2 includes a dial 23. The dial 23 is fixed on the top of the mounting frame 21 away from the feeding slot 16, and a plurality of labels 24 are symmetrically fixed on the surface of the dial 23 with the center of the circle as the center. A rotating plate 25 is rotatably installed on the top of the dial 23. A sending-out frame 216 is arranged on the inner wall of the top of the operation box 1, and a telescopic folding net 212 is fixedly connected between the sending-out frame 216 and the feeding slot 16. An electromagnetic door 15 is installed on one side surface of the operation box 1 corresponding to the positions of the two collection boxes 5, and a lifting component 3 is arranged on the inner wall of the other side of the operation box 1. The lifting component 3 includes a screw rod 32. A nut 33 is threadedly sleeved on the surface of the screw rod 32, and the nut 33 alternately presses against the tails of the two collection boxes 5. When using the device, the personal information of the user is input and recognized through the display screen 11 and the camera 12. After the information is confirmed, the user can send the sorted bidding materials into the feeding slot 16. Under the action of the driving component 2, the materials are stored in the partition 52 of the corresponding collection box 5 in sequence. After the dial 23 rotates a full circle, it can no longer rotate. At this time, the lifting component 3 has moved to the bottommost position, and both collection boxes 5 are full. The staff takes out and sorts all the materials stored inside.

[0026] In this embodiment, the driving assembly 2 further includes a disc 26. The mounting bracket 21 is rotatably installed with the disc 26 at the bottom of the rotation center of the rotating plate 25, and the disc 26 is fixedly connected to the rotation shaft of the rotating plate 25. An eccentric position at the bottom of the disc 26 is rotatably installed with a first connecting rod 27 through a rotating shaft, and the other end of the first connecting rod 27 is rotatably connected to a second connecting rod 28 through a rotating shaft. The top of the delivery frame 216 is fixed with a sliding seat 215 through a multi-section telescopic plate. A moving groove 17 is formed at the top of the operation box 1 corresponding to the moving path of the sliding seat 215, and a slider 210 is slidably connected inside the moving groove 17. The slider 210 is fixedly connected to the sliding seat 215. The top of the sliding seat 215 is rotatably installed with a shaft rod 29 through a bearing, and the shaft rod 29 is fixedly connected to the other end of the second connecting rod 28. The operation box 1 is fixed with a sliding rod 214 at the bottom of the moving groove 17. The sliding seat 215 is slidably sleeved on the sliding rod 214, and one end of the sliding rod 214 is fixed with a fixed block 213. The fixed block 213 is rotatably sleeved on the top of the screw rod 32. The top of the mounting bracket 21 is installed with a first transmission belt 22. One end pulley of the first transmission belt 22 is fixedly connected to the pulley of the second transmission belt 211, and the other end pulley of the first transmission belt 22 is fixedly connected to the rotation shaft of the rotating plate 25. Before a person identifies their identity, the rotating plate 25 is rotated once, and the rotating plate 25 rotates to the next number. At the same time, after the identity of the person is identified, a number is recorded. The rotating plate 25 drives the disc 26 to rotate. The first connecting rod 27 and the second connecting rod 28 cooperate, and the second connecting rod 28 pushes the slider 210 to slide along the moving groove 17, thereby advancing the position of the delivery frame 216. The positions of each partition 52 on the collection box 5 can be numbered in sequence, which is consistent with the identification number 24 of the identity, so that it is more convenient to correspond the identified person with the information one by one, facilitating statistics and sorting. Here, the moving speed of the delivery frame 216 and the descending speed of the screw block 33 can be adjusted by the sizes of the pulleys of the first transmission belt 22 and the second transmission belt 211, so that when the delivery frame 216 moves from one end of the collection box 5 to the other end, the flat plate 34 of the screw block 33 just no longer contacts the cylinder 56 at the rear end of the collection box 5.

[0027] In this embodiment, the lifting assembly 3 further includes a vertical groove 31. A vertical groove 31 is formed in the inner wall of the operation box 1. Both ends of the screw rod 32 are rotatably installed in the vertical groove 31 through bearings. The screw block 33 slides along the vertical groove 31. The top of the screw rod 32 penetrates through the operation box 1 and is installed with a second transmission belt 211. The other end pulley of the second transmission belt 211 is installed at the bottom of the other end of the mounting frame 21. Slide rails 51 are fixed on the inner walls on both sides of the collection box 5 in the operation box 1. An installation plate 54 is slidably inserted into the slide rails 51. Both sides of the collection box 5 are locked and connected to the installation plate 54 by bolts. A second spring 53 is fixed between one end of the installation plate 54 and the slide rail 51. A connection frame 55 is fixed at the bottom of the back of the collection box 5 where the installation plate 54 is located. A cylinder 56 is fixed on the surface of the connection frame 55. A flat plate 34 is fixed on the surface of the screw block 33. An inclined block is fixed at the bottom of the flat plate 34. The cylinder 56 alternately slides in contact with the inclined plate and the flat plate 34. Under the transmission connection of the first transmission belt 22 and the second transmission belt 211, when the rotating plate 25 rotates, the screw rod 32 will also rotate. The screw block 33 cooperates with the screw rod 32 and moves downward along the vertical groove 31. At this time, the flat plate 34 still contacts the cylinder 56, keeping the collection box 5 in the front position, receiving the first batch of materials one by one and sending them into the corresponding partitions 52. When the upper collection box 5 is loaded, at this time, the flat plate 34 just releases the extrusion effect on the cylinder 56. Through the elastic force of the second spring 53, the installation plate 25 slides along the slide rail 51, and the upper collection box 5 moves backward to give space for the movement of the delivery frame 216. At the same time, the upper electromagnetic door 15 is opened, which is convenient for the staff to separate the upper collection box 5 from the installation plate 54 and take out the materials stored inside. As the screw rod 32 continues to rotate, the inclined plate first contacts the cylinder 56, pushes the cylinder 56 outwards, and makes the lower collection box 5 continue to correspond to the delivery frame 216 for the loading work of the lower collection box 5.

[0028] In this embodiment, annular grooves 4 are formed on both side surfaces of the operation box 1, and cavities are provided inside the annular grooves 4. A vertical rod 41 is installed in the cavity of the operation box 1. A connecting plate 44 is slidably sleeved on the surface of the vertical rod 41, and the connecting plate 44 is fixedly connected to the delivery frame 216. A first spring 43 is sleeved on the surface of the vertical rod 41, and the other end of the first spring 43 is fixedly connected to the connecting plate 44. Slideways 42 are fixedly installed at the top and bottom of the cavity of the operation box 1, and the top and bottom of the vertical rod 41 slide along the slideways 42. The arrangement of the annular grooves 4 and the cavities on both sides of the operation box 1 facilitates the movement of the vertical rod 41 along the slideways 42. Moreover, horizontal openings are provided at the positions of the annular grooves 4 on both sides of the operation box 1 corresponding to the tops of the two collection boxes 5. These openings facilitate the movement of the vertical rod 41 to drive the connecting plate 44, thereby pulling the delivery frame 216 to move horizontally, and successively aligning the delivery frame 216 with each column of the collection box 5. When the vertical rod 41 moves to the vertical direction of the annular groove 4, the connecting plate 44 is pulled down by the elastic force of the first spring 43. At this time, the delivery frame 216 also descends to the top of the lower collection box 5 to continue filling the tender documents into the lower collection box 5. Since the disc 26 drives the first connecting rod 27 to rotate, the movement of the second connecting rod 28 is reciprocating. Therefore, the delivery frame 216 can continue to move along the lower horizontal opening to successively fill the lower collection box 5 with materials. During this process, when the connecting plate 44 drives the delivery frame 216 to descend, the telescopic folding net 212 can be unfolded, and at the same time, the multi-section telescopic plates connecting the sliding seat 215 and the delivery frame 216 will also extend to maintain connectivity. The annular groove 4 is actually a C-shaped groove, which can allow the delivery frame 216 to move horizontally twice and vertically once to switch the position of material delivery.

[0029] When using the device, before a person's identity is recognized, the turntable 25 is rotated once. The turntable 25 rotates to the next number. At the same time, after the person's identity is recognized, the number is recorded. The turntable 25 drives the disc 26 to rotate. The first connecting rod 27 and the second connecting rod 28 cooperate. The second connecting rod 28 pushes the slider 210 to slide along the moving groove 17, thereby advancing the position of the delivery frame 216. The positions of each partition 52 on the collection box 5 can be numbered in sequence, which is consistent with the identification number 24 of the identity recognition, so as to more conveniently correspond the identified person with the information one by one. The personal information of the user is input and recognized through the display screen 11 and the camera 12. After the information is confirmed, the user can send the sorted bidding materials into the feeding slot 16. Under the action of the driving assembly 2, the materials are stored in the partitions 52 of the corresponding collection box 5 in sequence. Under the transmission connection of the first transmission belt 22 and the second transmission belt 211, when the turntable 25 rotates, the screw rod 32 will also rotate. The screw block 33 cooperates with the screw rod 32 and moves downward along the vertical groove 31. At this time, the flat plate 34 still contacts the cylinder 56, keeping the collection box 5 in the front position, receiving and sending the first batch of materials one by one between the corresponding partitions 52. When the upper collection box 5 is loaded, at this time, the flat plate 34 just releases the extrusion on the cylinder 56. Under the elastic force of the second spring 53, the turntable 25 slides along the slide rail 51, and the upper collection box 5 moves backward to give space for the delivery frame 216 to move. At the same time, the upper electromagnetic door 15 is opened, which is convenient for the staff to separate the upper collection box 5 from the mounting plate 54 and take out the materials stored inside. As the screw rod 32 continues to rotate, the inclined plate contacts the cylinder 56 first, pushes the cylinder 56 outwards, and makes the lower collection box 5 continue to correspond to the delivery frame 216 for the filling work of the lower collection box 5. The annular grooves 4 and the cavities on both sides of the operation box 1 are provided to facilitate the vertical rod 41 to move along the slideway 42. And there are horizontal openings at the positions corresponding to the tops of the two collection boxes 5 in the annular groove 4. This opening can facilitate the vertical rod 41 to drive the connecting plate 44 to move, and then pull the delivery frame 216 to move horizontally, so that the delivery frame 216 corresponds to each column on the collection box 5 in turn. When the vertical rod 41 moves to the vertical direction of the annular groove 4, the connecting plate 44 is pulled down by the elastic force of the first spring 43. At this time, the delivery frame 216 will also drop to the top of the lower collection box 5 to continue filling the bidding materials into the lower collection box 5. Because the disc 26 drives the first connecting rod 27 to rotate, the movement of the second connecting rod 28 is reciprocating. Therefore, the delivery frame 216 can continue to move along the lower horizontal opening to fill the lower collection box 5 with materials in turn. During this process, when the connecting plate 44 drives the delivery frame 216 to drop, the telescopic folding net 212 can be unfolded, and the multi-section telescopic plate connecting the sliding seat 215 and the delivery frame 216 will also extend to maintain connectivity. The annular groove 4 is actually a C-shaped groove, which can allow the delivery frame 216 to move horizontally twice and vertically once to switch the position of material delivery. After the dial 23 rotates a full circle, it cannot continue to rotate.At this time, the lifting assembly 3 has moved to the bottommost position, and both collection bins 5 are fully loaded. The staff takes out and organizes all the materials stored inside.
