Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a vertical chain conveyor device. Background Technology

[0002] In the fields of industrial production and logistics transportation, vertical conveying equipment is a key piece of equipment for transferring materials at different heights, and is widely used in industries such as food processing, pharmaceutical manufacturing, and warehousing logistics. Traditional vertical conveying equipment often uses belt conveyors and bucket elevators, but when faced with irregularly shaped materials, heavy materials, or conveying scenarios requiring precise positioning, it often suffers from problems such as insufficient stability, easy material detachment, and poor adaptability.

[0003] While existing chain-plate vertical conveyor systems offer certain advantages in load-bearing capacity, they still have many limitations. For example, the material fixing structure is simple and difficult to adapt to materials of different sizes and weights. During vertical conveying, the materials are prone to shifting or even falling due to swaying. Furthermore, most equipment's material positioning components lack intelligent adjustment capabilities and cannot automatically adjust the clamping strength according to the material's weight, which not only affects conveying accuracy but may also cause material damage due to over-clamping.

[0004] To address the aforementioned issues, there is an urgent need to develop a vertical chain conveyor system with efficient drive, adaptive material fixing, and precise positioning capabilities. This system aims to resolve the shortcomings of traditional equipment in terms of stability, adaptability, and intelligence during vertical conveying, thereby meeting the demands of modern industrial production for efficient, precise, and safe vertical material transfer. Utility Model Content

[0005] Based on the above description, this utility model provides a vertical chain plate conveying device to solve the shortcomings of existing chain plate vertical conveying devices, such as the single material fixing structure, inability to adapt to materials of different sizes and weights, falling during the conveying process, and inability to automatically adjust the clamping strength according to the material weight, which easily leads to material damage.

[0006] This utility model is achieved through the following technical solution:

[0007] A vertical chain conveyor includes:

[0008] The frame serves as the installation foundation for the entire conveying equipment and is divided into three parts: the first horizontal section, the second horizontal section, and the vertical section. It is externally fixed to the ground using bolts.

[0009] The conveying assembly is a chain plate conveyor belt that is wrapped around the inside of the frame. The surface of the chain plate is also provided with mounting grooves, and a fixed mold can be detachably installed through the mounting grooves.

[0010] An auxiliary positioning component is installed inside the fixed mold and automatically controls the clamping strength according to the weight of the material.

[0011] The drive assembly, located inside the frame, is used to drive the conveyor assembly for cyclical transport.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the drive assembly includes several rollers disposed on the first horizontal section, the vertical section, and the second horizontal section, and both ends of each roller are rotatably connected to the inner wall of the frame through ball bearings, and both ends of the roller are also provided with sprockets, and multiple sprockets are connected by chain drive. The outer wall of the frame is also provided with a drive motor, and the output end of the drive motor is connected to one of the rollers through a gear reducer.

[0014] Furthermore, the fixed mold includes a connecting part and a hopper, wherein the connecting part is hollow inside and a locking disc is rotatably mounted thereon, and the four sides of the connecting part are respectively provided with slots, and a locking block is slidably mounted inside the slots through a groove structure. The inward end of the locking block extends to the bottom of the locking disc, and the top surface of the locking block is also provided with an arc-shaped insert. The locking disc is equipped with a spiral groove, and the arc-shaped insert is movably inserted into the groove and moves horizontally as the locking disc rotates.

[0015] Furthermore, the top surface of the locking disc is also provided with a worm wheel, and a worm is provided on one side of the worm wheel. The worm is connected to the worm wheel in a transmission manner. The two ends of the worm are respectively rotatably connected to the inner wall of the connecting part through a bearing structure. One end of the worm extends to the outside of the connecting part and is provided with an adjusting cap.

[0016] Furthermore, a spring damper is provided on the bottom surface of the mounting groove. Multiple spring dampers are provided, and a push plate is provided on the top. The bottom surface of the push plate is in close contact with the bottom surface of the connecting part and applies upward thrust.

[0017] Furthermore, the auxiliary positioning component includes a pressure sensor disposed between the hopper and the connecting part, and an electromagnetic coil disposed on the bottom surface of the hopper. The electromagnetic coil is equipped with a controller and a battery, and the pressure sensor is electrically connected to the controller via a wire.

[0018] Furthermore, the inner wall of the hopper is provided with several air bladders, which are interconnected by air pipes and connected to an air pump. The air pump is electrically connected to a controller via wires.

[0019] Furthermore, the hopper is equipped with a metal detector, which is electrically connected to the controller.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0021] This application improves upon the existing chain plate vertical conveyor by combining the fixing mold on the chain plate with the air bladder and magnetic structure to form a new fixing structure. This structure can automatically control the clamping strength of the material according to its weight, ensuring the stability of the material during the conveying process, preventing it from falling off and shifting its position, and preventing damage to the material from excessive clamping.

[0022] In addition, the fixed mold in this application adopts a driving method similar to a three-jaw chuck, which allows the locking block to flexibly expand outward or retract inward. This enables the fixed mold to be replaced in a quick disassembly and assembly manner without the need for tools. It can be completed with just two hands, making it very convenient to use.

Detailed Implementation

[0029] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0031] Combination Figure 1-5 As shown, a vertical chain conveyor includes:

[0032] Frame 1 serves as the installation foundation for the entire equipment, which is an external frame made of metal plates and fixed to the ground by anchor bolts or other means.

[0033] The conveying component 2 is a chain plate 21 type conveyor belt, which is set inside the frame 1 to assist in the cyclic transportation of materials;

[0034] The auxiliary positioning component 3 is set on the top surface of the conveying component 2 to assist in clamping and fixing the material, preventing it from falling off due to factors such as vibration.

[0035] The drive assembly 4 includes a conveying roller and a drive motor, serving as the drive source for the chain plate 21 type conveyor belt.

[0036] Specifically, in this embodiment, the chain plate 21 on the conveying component 2 should have an installation groove 22, and a corresponding fixing mold 5 should be set in the installation groove 22 to cope with the conveying of different materials, such as wood, ceramics and metal materials.

[0037] Based on this, conventional installation methods often use bolts for direct fixing. However, this method is prone to corrosion after long-term use, and the fixing mold 5 needs to be replaced when changing materials for production and transportation. This bolt structure is very inconvenient to disassemble and assemble, so it needs to be further improved.

[0038] In this embodiment, the fixed mold 5 is divided into a connecting part 51 and a hopper 52. The connecting part 51 is located at the bottom, and the top is fixedly connected to the hopper 52. The connecting part 51 can be embedded in the mounting groove 22. A locking plate 53 is movably installed in the space reserved inside the connecting part 51. The bottom surface of the locking plate 53 is provided with a spiral groove. In addition, a slot is provided on the outer side wall of the connecting part 51. A locking block 54 is movably installed in the slot. The locking block 54 and the side wall of the slot are limited by a groove structure, so that the locking block 54 can slide stably against the side wall of the slot.

[0039] In addition, an arc-shaped insert is provided on the bottom surface of the inward end of the locking block 54. The arc-shaped insert is adapted to the groove. Therefore, when the locking disc 53 is driven to rotate, the arc-shaped inner wall of the groove can be used to force the insert to drive the entire locking block 54 to move in the horizontal direction, thereby realizing the purpose of unfolding or retracting the locking block 54. Furthermore, a limiting groove is also provided on the inner side wall of the mounting groove 22. When the locking block 54 is unfolded outward, it is inserted into the limiting groove, thereby locking and fixing the connecting part 51 and the chain plate 21.

[0040] During actual assembly, there is a certain assembly gap between the locking block 54 on the connecting part 51 and the limiting groove on the inner wall of the mounting groove 22. Therefore, to avoid the shaking caused by this fitting gap, an elastic pad should be provided on the surface of the locking block 54. In addition, a spring damper should be installed on the bottom surface of the mounting groove 22. Multiple spring dampers should be provided, and a push plate 23 should be provided on the top of the multiple spring dampers. The top surface of the push plate 23 should be in close contact with the bottom surface of the connecting part 51 and should always apply a pushing force upward. In this way, the pushing force can make the locking block 54 fit tightly against the inner wall of the limiting groove, preventing the entire fixed mold 5 from shaking.

[0041] To facilitate the disassembly of the fixed mold 5 by the staff and to prevent the locking plate 53 from reversing due to equipment vibration and affecting the connection effect, a worm wheel should be provided on the top surface of the locking plate 53. The worm wheel is arranged concentrically with the locking plate 53, and a worm is provided on one side of the worm wheel. The worm meshes with the worm wheel, and both ends of the worm are movably connected to the inside of the connecting part 51 through a bearing structure. One end of the worm should extend to the outer wall of the connecting part 51 and be equipped with an adjusting cap.

[0042] The auxiliary positioning component 3 includes a controller 32, a pressure sensor 31, an electromagnetic coil 33, and a battery 34. The controller 32 is preferably a Limaisheng NIMC301-A, embedded in the inner bottom surface of the hopper 52, and electrically connected to various components via wires for intelligent control. The pressure sensor 31 is preferably a German HBM S40A series sensor, positioned between the hopper 52 and the connecting part 51 to weigh the material entering the hopper 52 and transmit the detected data to the controller 32. The electromagnetic coil 33 is located on the inner bottom surface of the hopper 52, covering most of the bottom area. Alternatively, multiple electromagnets in a rectangular array can be used instead of the electromagnetic coil 33 structure, with their on / off switches electrically connected to the controller 32, allowing the controller 32 to automatically open based on detection information, thereby assisting material transport via magnetic attraction. The battery 34 is located on the inner bottom surface of the hopper 52 to power the aforementioned equipment.

[0043] The above structure is mainly designed for ordinary metal parts. Therefore, the adsorption capacity of the hopper 52 can be enhanced by electromagnetism. This adsorption method can then be used to prevent materials from falling during vertical transportation, effectively enhancing the stability of the conveying process.

[0044] Furthermore, in order to expand the applicability of the entire conveying equipment, a metal detector 35 should be additionally installed inside the hopper 52. The metal detector 35 is preferably a Nordin 21EHERO-500QD and is electrically connected to the controller 32. This detection method is used to determine whether the material is metal. When the material is metal, the controller 32 activates the magnetic attraction structure to attract it.

[0045] If the transported material is non-metallic, to ensure its stability, an airbag 36 should be installed on the inner wall of the hopper 52, and an air pump 37 should be installed simultaneously. The airbag 36 is connected to the air pump 37 through an air pipe, and the air pump 37 is electrically connected to the controller 32 through a wire. Its main purpose is to assist in the use of some large and irregularly shaped parts. Through flexible clamping, it can firmly fix them and avoid damage to the material due to excessive clamping force. Moreover, the clamping force of the airbag 36 can be adaptively adjusted according to the weight of the material, ensuring that the material will not fall during vertical lifting. In the combination of the above two fixing methods, the airbag is used first to clamp the metal parts, ensuring that the metal parts are located in the center and that the force is evenly distributed on all four sides. Then, the magnetic suction structure is activated to further enhance the auxiliary fixing effect.

[0046] During unloading, a reflector should be installed on the side wall of the frame 1 near the unloading port, and a sensor should be installed at the connection between the connecting part 51 and the hopper 52. The two together form a through-beam photoelectric sensor, such as the German SICK WSE4S-3P1430V, Pepperl+Fuchs GD18 / GV18 / 115 / 120, etc. The purpose is to assist the controller 32 in automatically closing the above clamping structure when it is in the unloading area, so that the material can fall smoothly and achieve the purpose of transfer and conveying.

[0047] The drive assembly 4 includes rollers and a drive motor. The entire frame is divided into a first horizontal section, a second horizontal section, and a vertical section. Multiple conveying rollers are arranged in the above three areas respectively, and ball bearings are used to make both ends rotatably connected to the inner wall of the frame. The drive motor is arranged on one side of the frame to drive one of the rollers. The ends of multiple rollers are equipped with sprockets and are connected to each other by chains, thereby driving the entire chain plate 21 type conveyor belt to circulate.

[0048] At the ends of the first and second horizontal sections, there are arc-shaped bends. These bends should be equipped with pressure roller assemblies, namely pressure rollers and pressure roller shafts, to assist transmission components such as chains in adjusting tension or changing the transmission direction, and to ensure smooth power transmission.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
