Description

Technical Field

[0001] The present application relates to the technical field of conveying devices, and in particular to an automated conveying device for continuously guiding materials at high and low positions. Background Art

[0002] After being sealed and packaged, bagged foods often need to be transported to a designated location for boxing and storage via a conveyor, which is usually a food conveyor, through which the bagged foods are transported automatically.

[0003] Most existing bagged food conveying devices include a mounting frame and a conveyor belt mounted on the mounting frame. The mounting frame is placed horizontally on the ground, and the bagged food is placed on the conveyor belt as material. As the conveyor belt runs on the mounting frame, the material is moved from one end of the mounting frame to the other end.

[0004] However, most conventional material conveying devices can only transport materials at the same level, and are inconvenient to transport materials between different levels, which greatly affects the material transportation efficiency of the conveying device. Summary of the Invention

[0005] In order to improve the problem that ordinary conveying devices are inconvenient to transport materials between different horizontal heights, the present application provides an automated conveying device that continuously guides materials at high and low levels.

[0006] The automatic conveying device for continuous high and low-level material guidance provided in this application adopts the following technical solutions:

[0007] An automated conveying device for continuous high and low-level material guidance includes a carrying mechanism and a pushing mechanism; the carrying mechanism includes high and low-level conveying frames and a carrying conveyor belt and a driving motor arranged on the high and low-level conveying frames, and the driving motor is used to drive the carrying conveyor belt to operate on the high and low-level conveying frames; the pushing mechanism includes multiple groups of pushing frames, all of which are arranged at intervals on the carrying conveyor belt, and the pushing frames are used to abut the material on the carrying conveyor belt, so that the material and the carrying conveyor belt are displaced synchronously.

[0008] By adopting the above technical solution, the high and low position conveying racks have positions at different heights, the materials to be transported are placed on the carrying conveyor belt, the pushing rack is in contact with the materials, the driving motor drives the carrying conveyor belt to operate, and the materials move synchronously with the carrying conveyor belt to realize the transportation of materials between different heights; this process improves the applicability of the conveying device when transporting materials, and effectively ensures the transportation efficiency of the conveying device for materials.

[0009] In a specific possible implementation scheme, the high and low position conveying frames include a material receiving conveying frame, a transfer conveying frame and a splicing frame. The height dimension of the transfer conveying frame is greater than the height dimension of the material receiving conveying frame. The splicing frame is obliquely arranged between the material receiving conveying frame and the transfer conveying frame to connect the material receiving conveying frame and the transfer conveying frame; the carrying conveyor belt is simultaneously arranged on the material receiving conveying frame, the splicing frame and the transfer conveying frame, and the driving motor is arranged on the material receiving conveying frame to drive the carrying conveyor belt to operate simultaneously on the material receiving conveying frame, the splicing frame and the transfer conveying frame.

[0010] By adopting the above technical solution, the height dimension of the transfer conveyor frame is greater than the height dimension of the material receiving conveyor frame, and the carrying conveyor belt is installed on the material receiving conveyor frame, the lap frame and the transfer conveyor frame at the same time to transport materials, so that materials can be transported between different heights, thereby effectively ensuring the transportation efficiency of the conveying device for materials.

[0011] In a specific possible implementation manner, each group of the pusher racks includes at least two pusher arc plates, and all of the pusher arc plates are arranged on the carrying conveyor belt.

[0012] By adopting the above technical solution, the pusher arc plate abuts against the material on the carrying conveyor belt, so that the material moves synchronously with the carrying conveyor belt, thereby effectively ensuring the efficiency of transporting materials on the carrying conveyor belt; in addition, the pusher arc plate with a certain curvature increases the contact area between the abutting arc plate and the material, ensuring the stability of the pusher arc plate abutting against the material.

[0013] In a specific embodiment, each of the pusher arc plates is glued to the carrying conveyor belt.

[0014] By adopting the above technical solution, the pusher arc plate fixed by glue can realize the rapid positioning of the pusher arc plate on the carrying conveyor belt. At the same time, it is easy to disassemble the pusher arc plate that has been used for a long time for maintenance and replacement.

[0015] In a specific feasible implementation scheme, the pushing mechanism also includes multiple groups of positioning components, each group of the positioning components includes at least two extension plates and at least two positioning bolts; at least two of the extension plates are respectively arranged on opposite sides of the pushing arc plate, and the carrying conveyor belt is provided with a sedimentation trough for the extension plate and the pushing arc plate to be pushed into at the same time, and one of the positioning bolts is used to position an extension plate on the carrying conveyor belt.

[0016] By adopting the above technical solution, the extension plate increases the contact area between the pusher arc plate and the carrying conveyor belt. The extension plates arranged on the opposite sides of the pusher arc plate can ensure the position stability of the pusher arc plate on the carrying conveyor belt; after the positioning bolts fix the extension plate and the carrying conveyor belt, the connection strength of the extension plate and the carrying conveyor belt is guaranteed, and at the same time, it is convenient for the operator to disassemble the pusher arc plate.

[0017] In a specific feasible implementation scheme, the pushing mechanism also includes multiple groups of clamping assemblies, and one group of the clamping assemblies is correspondingly arranged on a group of pushing racks; each group of the clamping assemblies includes a through bolt and a connecting nut, and the through bolt is simultaneously passed through all the pushing arc plates of a group of pushing racks, and the connecting nut is threadedly connected to the through bolt for connecting all the pushing arc plates of a group of pushing racks.

[0018] By adopting the above technical solution, after the through bolts pass through all the pusher arc plates of a group of pusher racks at the same time, the connecting nuts are threadedly tightened on the through bolts, so that all the pusher arc plates that abut against each other are fixedly connected as a whole, thereby helping to improve the abutment stability of the pusher rack against the material.

[0019] In a specific feasible implementation scheme, the pushing mechanism also includes multiple groups of limit assemblies, and one group of the limit assemblies is correspondingly arranged on a group of pushing racks; each group of the limit assemblies includes at least one limit block, and at least one limit block is arranged on at least one pushing arc plate of a group of pushing racks, and the remaining pushing arc plates of a group of pushing racks are provided with plug-in grooves for the limit blocks to be inserted into.

[0020] By adopting the above technical solution, after the limit block is pressed into the inner cavity of the plug-in slot, the connection tightness of the adjacent pushing arc plates after they are pressed against each other is increased, thereby improving the stability when the pushing rack and the material are pressed against each other, which helps to ensure the transportation efficiency of the conveying device for materials.

[0021] In a specific embodiment, each set of the limiting components further includes an interference piece, and the interference piece is tightly fitted between the limiting block and the side wall of the plug-in slot.

[0022] By adopting the above technical solution, the interference fit is pressed between the limit block and the side wall of the plug-in slot through advanced compression deformation, so as to reduce the connection gap of the limit block in the plug-in slot, thereby effectively ensuring the connection strength of adjacent pusher arc plates after being connected, and improving the abutment stability of the pusher rack on the material.

[0023] In a specific possible implementation scheme, the conveying device also includes a protective mechanism, which includes a plurality of protective plates; all of the protective plates are relatively arranged on the carrying conveyor belt, all of the protective plates are distributed along the extension direction of the carrying conveyor belt, and adjacent protective plates are abutted against each other to form a material transport channel on the carrying conveyor belt, and all of the pushing racks are located in the material transport channel.

[0024] By adopting the above technical solution, adjacent protective plates offset each other to form a protective wall on the carrying conveyor belt for blocking materials, thereby effectively reducing the phenomenon of materials detaching from the carrying conveyor belt and ensuring the transportation stability of materials on the carrying conveyor belt.

[0025] In a specific feasible implementation scheme, the protective mechanism also includes multiple groups of abutment components, one group of the abutment components is used to connect two adjacent protective plates; each group of the abutment components includes an elastic member and a snap-in block, and each protective plate is provided with preset grooves on opposite sides, and the snap-in block is set in one of the preset grooves of any protective plate through the elastic member, and the other preset groove of each protective plate is empty; the two adjacent protective plates abut against each other, and the snap-in block on one of the protective plates abuts against the empty preset groove of the other protective plate.

[0026] By adopting the above technical solution, the end of the clamping block away from the elastic part can be inserted into the control preset groove of the adjacent protective plate, so that the two adjacent protective plates are connected after being pushed against each other, which helps to improve the connection strength of the adjacent protective plates and ensure the stability of the protective plate's protection of the material.

[0027] In summary, this application has the following beneficial technical effects:

[0028] 1. The high and low conveyor racks are located at different heights. The material to be transported is placed on the conveyor belt. The pusher rack contacts the material. The drive motor drives the conveyor belt to operate. The material moves synchronously with the conveyor belt to achieve the transportation of materials between different heights. This process improves the applicability of the conveyor device in transporting materials and effectively ensures the transportation efficiency of the conveyor device for materials.

[0029] 2. Adjacent protective plates offset each other to form a protective wall on the carrying conveyor belt to block materials, thereby effectively reducing the phenomenon of materials escaping from the carrying conveyor belt and ensuring the transportation stability of materials on the carrying conveyor belt.

[0037] The embodiments of the present application disclose an automated conveying device for continuously guiding materials at high and low positions.

[0038] The application will be further described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] Reference Figure 1-5 The conveying device includes a carrier mechanism 1, a pushing mechanism 2, and a protective mechanism 3. The carrier mechanism 1 further includes a high and low-level conveyor frame 11, a carrying conveyor belt 12, and a drive motor 13. The pushing mechanism 2 and the protective mechanism 3 are arranged on the carrying conveyor belt 12, and the carrying conveyor belt 12 and the drive motor 13 are arranged on the high and low-level conveyor frame 11. The high and low-level conveyor frame 11 has different levels. The material is placed on the carrying conveyor belt 12. The protective mechanism 3 is used to prevent the material from detaching from the carrying conveyor belt 12. The pushing mechanism 2 abuts against the material, causing the material to move synchronously with the carrying conveyor belt 12, thereby allowing the material to be transported between different heights, ensuring the transportation efficiency of the conveying device for the material.

[0041] Reference Figure 1 The high and low conveyor racks 11 include a receiving conveyor rack 111, a transfer conveyor rack 112, and a splicing rack 113. In this embodiment, the receiving conveyor rack 111, the transfer conveyor rack 112, and the splicing rack 113 are all made of steel rods, with the transfer conveyor rack 112 being taller than the receiving conveyor rack 111. After the receiving conveyor rack 111 and the transfer conveyor rack 112 are placed on the ground at a certain distance, the splicing rack 113 is welded obliquely between the receiving conveyor rack 111 and the transfer conveyor rack 112. At this point, the receiving conveyor rack 111, the splicing rack 113, and the transfer conveyor rack 112 are connected together to form a single unit.

[0042] Reference Figure 1In this embodiment, the carrying conveyor belt 12 can be a modular conveyor belt made of hard plastic. One end of the carrying conveyor belt 12 passes through the material receiving conveyor frame 111, the splicing frame 113, and the transfer conveyor frame 112 in sequence, and then is connected to the other end of the lengthwise direction to form a closed loop on the material receiving conveyor frame 111, the splicing frame 113, and the transfer conveyor frame 112.

[0043] Reference Figure 1 The drive motor 13 is mounted on the receiving conveyor frame 111. When the drive motor 13 rotates forward, the carrying conveyor belt 12 rotates clockwise on the high and low position conveyor frame 11. At this time, the material can be transported from the end of the receiving conveyor frame 111 away from the splicing frame 113 to the end of the transfer conveyor frame 112 away from the splicing frame 113, thereby allowing the material to be transported from a lower position to a higher position. When the drive motor 13 rotates backward, the material can be transported from a higher position to a lower position.

[0044] Reference Figure 1 and Figure 2 The pushing mechanism 2 includes multiple groups of pushing racks 21. All pushing racks 21 are spaced and evenly distributed on the carrying conveyor belt 12. The material is placed between adjacent pushing racks 21, and then the pushing racks 21 abut against the material to achieve synchronous displacement of the material and the carrying conveyor belt 12.

[0045] Reference Figure 2 Each set of pusher racks 21 includes at least two pusher arc plates 211. In this embodiment, each set of pusher racks 21 may include three pusher arc plates 211. The three pusher arc plates 211 are distributed along the width of the carrying conveyor belt 12 and abut against each other. Each pusher arc plate 211 is glued to the carrying conveyor belt 12 to abut against materials placed on the carrying conveyor belt 12.

[0046] Reference Figure 2 The protective mechanism 3 includes multiple protective plates 31, each made of PVC. Each protective plate 31 is slightly bendable and deformable, and all protective plates 31 are glued to the conveyor belt 12. In this embodiment, all protective plates 31 are arranged in two rows, one on each side of the width of the conveyor belt 12. All protective plates 31 in a row are grouped into three groups, with each protective plate 31 in each group abutting against a second protective plate 31 on each side of the width. All protective plates 31 in each row extend along the length of the conveyor belt 12, forming a material transport channel 4 on the conveyor belt 12. All pusher racks 21 are located within the material transport channel 4 to prevent material from falling off the conveyor belt 12 during transportation.

[0047] The implementation principle of the automatic conveying device with high and low position continuous material guidance in the embodiment of the present application is: there is a certain height difference between the material receiving conveying frame 111 and the transfer conveying frame 112. After the carrying conveyor belt 12 is installed on the material receiving conveying frame 111, the overlapping frame 113 and the transfer conveying frame 112 at the same time, the material to be transported can be placed on the carrying conveyor belt 12. At this time, the pushing arc plate 211 is in contact with the material.

[0048] When the drive motor 13 drives the conveyor belt 12 to move, the material contacted by the pusher arc plate 211 moves synchronously with the conveyor belt 12. The protective plate 31 blocks the material along the width of the conveyor belt 12, preventing it from escaping the conveyor belt 12. This process allows materials to be transported between two locations at different heights, effectively ensuring the conveyor device's material transportation efficiency.

[0049] Example 2

[0050] The difference between Example 2 of the present application and Example 1 is that, referring to Figure 3 and Figure 4 The pushing mechanism 2 also includes multiple groups of positioning components 22, multiple groups of tightening components 23, and multiple groups of limiting components 24.

[0051] Reference Figure 3 and Figure 5 In addition, the protection mechanism 3 also includes multiple groups of abutment components 32.

[0052] Reference Figure 3 and Figure 4 A set of positioning assemblies 22 is used to removably mount a pusher arc plate 211 on the carrying conveyor belt 12. Each set of positioning assemblies 22 includes at least two extension plates 221 and at least two positioning bolts 222. In this embodiment, each set of positioning assemblies 22 can include two extension plates 221 and two positioning bolts 222. Each pair of extension plates 221 is integrally formed on either side of the width of the pusher arc plate 211, with the sidewalls of the extension plates 221 facing the ground coplanar with the sidewalls of the pusher arc plate 211 facing the ground.

[0053] Reference Figure 3 and Figure 4 The conveyor belt 12 is provided with a settling trough 121. All the pusher arcs 211 of a set of pusher racks 21 and the extension plates 221 provided on the pusher arcs 211 can simultaneously press into the side walls of the settling trough 121. A positioning bolt 222 passes through each extension plate 221 and is screwed into a pre-set threaded groove in the bottom wall of the settling trough 121, securing the extension plate 221 to the side wall of the settling trough 121. This allows the pusher arcs 211 to be quickly and stably installed on the conveyor belt 12.

[0054] Reference Figure 3and Figure 4 A set of abutment components 23 is used to connect all the pusher arc plates 211 of a set of pusher racks 21 to ensure the abutment stability of the pusher racks 21 against materials of large mass and volume. Each set of abutment components 23 includes a penetration bolt 231 and a connecting nut 232. The penetration bolt 231 simultaneously passes through the three pusher arc plates 211 of a set of pusher racks 21. The connecting nut 232 is screwed onto the penetration bolt 231, so that the three pusher arc plates 211 of a set of pusher racks 21 are fixedly connected as a whole, thereby improving the abutment stability of the pusher rack 21 against the materials.

[0055] Reference Figure 4 , a group of limiting components 24 is correspondingly arranged on a group of pusher racks 21 to strengthen the connection strength after all the pusher arc plates 211 of a group of pusher racks 21 are offset against each other. Each group of limiting components 24 includes at least one limiting block 241. In this embodiment, the number of limiting blocks 241 of the limiting component 24 can be two, and the two limiting blocks 241 are respectively integrally formed on the two pusher arc plates 211 of a group of pusher racks 21. The remaining pusher arc plates 211 of each group of pusher racks 21 are provided with plug-in slots 2111, and the inner diameter size of the plug-in slots 2111 is adapted to the outer circumferential size of the limiting blocks 241. After the three pusher arc plates 211 are offset against each other, a limiting block 241 is inserted into the inner cavity of a plug-in slot 2111 to improve the connection strength after the adjacent pusher arc plates 211 are offset against each other, thereby helping to improve the abutment stability of the pusher rack 21 on the material.

[0056] Reference Figure 4 To enhance the tightness of the connection between adjacent pusher arc plates 211 after they abut against each other, each set of stopper assemblies 24 also includes an interference fit 242. In this embodiment, the interference fit 242 can be a rubber sleeve with a high static friction coefficient and easy deformation. The interference fit 242 is sleeved onto each stopper block 241. When the stopper block 241 abuts against the inner cavity of the insertion slot 2111, the interference fit 242 compresses and deforms to tighten between the stopper block 241 and the sidewall of the insertion slot 2111.

[0057] Reference Figure 5 A set of abutment components 32 is used to connect the two abutting protective plates 31 to ensure the stability of the protective plates 31 against the material. Each set of abutment components 32 includes an elastic member 321 and a clamping block 322, wherein the elastic member 321 is a steel compression spring.

[0058] Reference Figure 5, each protective plate 31 is provided with a preset groove 311 on both sides in the width direction, and the inner diameter of the preset groove 311 is adapted to the outer circumferential size of the clamping block 322. In this embodiment, any one of the two preset grooves 311 of a protective plate 31 can be in an empty state. One end of the elastic member 321 in the length direction is welded to the side wall of the other preset groove 311 of a protective plate 31, and the clamping block 322 is welded to the other end of the elastic member 321 in the length direction. When the elastic member 321 is in a freely extended state, the end of the clamping block 322 close to the elastic member 321 is located in the preset groove 311 where the elastic member 321 is installed, and the end of the clamping block 322 away from the elastic member 321 is located outside the protective plate 31.

[0059] Reference Figure 3 and Figure 5 When two adjacent protective plates 31 abut against each other, the operator bends one of the protective plates 31 to create a gap between the two protective plates 31. The operator then inserts the engaging block 322 into the empty slot 311 of the other protective plate 31 to increase the connection strength between the two adjacent protective plates 31, thereby improving the protective stability of the protective plates 31 against materials.

[0060] The operating principle of the automated conveying device for continuous high- and low-level material feeding according to the present embodiment is as follows: the limit block 241 presses into the inner cavity of the insertion slot 2111 to improve the tightness of the connection between all the pusher arc plates 211 of a group of pusher racks 21. After the insertion bolt 231 simultaneously passes through all the pusher arc plates 211 in a group of pusher racks 21, the connecting nut 232 is threaded onto the insertion bolt 231, fixing all the pusher arc plates 211 of a group of pusher racks 21 as a whole, thereby ensuring the stability of the pusher racks 21 in contact with the material.

[0061] The extension plate 221 increases the contact area between the pusher arc 211 and the conveyor belt 12. The positioning bolts 222 securely connect the extension plate 221 and the conveyor belt 12, ensuring the stability of the pusher arc 211 on the conveyor belt 12 and improving the contact stability of the arc against the material. Furthermore, this allows operators to quickly remove the pusher arc 211, which has aged due to long-term use, for maintenance and replacement.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
