Description

Technical Field

[0001] This utility model belongs to the field of bamboo basket production technology, specifically relating to a conveyor belt type constant temperature control box. Background Technology

[0002] After production, bamboo baskets need to be dried and shaped, which is generally done using conveyor belt constant temperature drying equipment. After the woven bamboo baskets are placed on the conveyor unit, the conveyor unit transports the bamboo baskets through the constant temperature control unit (i.e., constant temperature oven) for drying before output.

[0003] However, current constant temperature control units generally have exhaust vents on the inner wall of the outer casing, and blow air onto the side of the bamboo basket through the exhaust vents to dry it at a constant temperature. Since the bamboo basket is placed on the conveyor belt of the conveyor unit, its bottom is in contact with the conveyor belt, so the hot air cannot effectively dry the bottom of the bamboo basket.

[0004] In view of this, the present invention provides a conveyor belt type constant temperature control box to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conveyor belt type constant temperature control box, comprising a chain mesh conveying unit for conveying materials, and a constant temperature control unit disposed above the chain mesh conveying unit for drying the materials;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model relates to a conveyor belt type constant temperature control box, such as Figures 1-5 As shown, it includes a chain conveyor unit 1 for conveying materials, a constant temperature control unit 2 disposed above the chain conveyor unit 1 for drying the conveyed materials, and a control unit 3 disposed on the outer surface of the constant temperature control unit 2. The control unit 3 is a common PLC controller or industrial computer.

[0025] The chain-mesh conveyor unit 1 is essentially a common conveyor belt, comprising a frame 11 and several conveyor rollers 12 rotatably connected to the frame 11. A breathable conveyor chain mesh is fitted onto each conveyor roller 12, and materials are conveyed by placing them on the chain mesh. As shown in the figure, several through holes 111 are provided on both sides of the frame 11. These through holes 111 connect to the inner side of the conveyor chain mesh and are located between two adjacent conveyor rollers 12. The number of through holes 111 can be determined according to the actual length of the constant temperature control unit 2.

[0026] Among them, such as Figures 2-3 As shown, the constant temperature control unit 2 includes an outer shell 21 that is shaped like an inverted "U". The outer shell 21 is connected to the frame 11 and together with the frame 11 forms a drying chamber with a square cross-section. The openings at both ends of the drying chamber can be relatively sealed by heat insulation strips to reduce heat loss. In actual use, a temperature sensor connected to the control unit 3 needs to be installed inside the drying chamber to measure the temperature inside the drying chamber and control the operation of the components in the constant temperature control unit 2 through the control unit 3. A guide cavity 22 is provided inside the outer shell 21. An exhaust device 23 connected to the drying chamber and a hot air device 24 connected to the guide cavity 22 are respectively provided on the top and outer side of the outer shell 21. The exhaust device 23 and the hot air device 24 are commonly used exhaust fans and electric heating fans in current drying devices. They are both connected to and controlled by the control unit 3. The exhaust device 23 is used to discharge the moisture accumulated at the top of the drying chamber. At the same time, by controlling its speed, the air convection inside the drying chamber can be accelerated or slowed down to cooperate with the hot air device 24 to achieve constant temperature control inside the drying chamber. The inner side of the outer casing 21 is also connected to at least one set of air ducts 25 that communicate with the flow guide cavity 22 and extend into the inner side of the conveyor chain of the chain-type conveyor unit 1 through the through hole 111. The surface of the air duct 25 is provided with exhaust holes 26 that are opposite to the inner side of the conveyor chain.

[0027] In use, the hot air device 24 generates hot air which is blown into the guide cavity 22. Through the air guide pipe 25 connected to the guide cavity 22, the hot air can enter the air guide pipe 25 and be discharged from the exhaust hole 26 on the surface of the air guide pipe 25. Based on the principle of hot air rising, the hot air discharged from the exhaust hole 26 will rise and be blown through the conveyor chain to the bottom surface of the material conveyed on the conveyor chain, so as to achieve comprehensive and uniform drying of the material.

[0028] Furthermore, the inner side of the outer casing 21 is provided with at least one set of exhaust vents 27 that connect the guide cavity 22 and the drying cavity. The exhaust vents 27 are elongated and spaced along the inner wall of the outer casing 21, and their extension direction is parallel to the conveying direction of the chain mesh conveying unit 1, so that hot air is blown onto the material at all times during material conveying; at the same time, in order to better guide the hot air to the material surface using the exhaust vents 27, the exhaust vents 27 can be inclined, with their inclination direction pointing towards the chain mesh conveying unit 1, so that the hot air is guided through the exhaust vents 27, so that the hot air directly acts on the material surface to achieve efficient drying.

[0029] Furthermore, to facilitate the assembly and disassembly of the air duct 25, a connecting hole 28 is provided at the connection between the outer shell 21 and the air duct 25 to connect to the flow guide cavity 22. The inner wall of the connecting hole 28 has a threaded structure and is coaxially arranged with the through hole 111. At the same time, the end of the air duct 25 is provided with a threaded rib that matches the thread of the inner wall of the connecting hole 28, so that the two can be threadedly connected.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
