Description

Technical Field

[0001] This utility model relates to the field of mesh belt furnace technology, and in particular to a conveying device suitable for extending mesh belt furnaces and preventing material mixing. Background Technology

[0002] A mesh belt furnace is a continuous solid-state heat treatment equipment widely used in powder metallurgy, cemented carbide tools, and other fields. The furnace body typically consists of a feeding section, a pre-sintering section, a sintering section, a slow cooling section, a water cooling section, and a discharge section. The mesh belt drive system consists of a high-temperature resistant mesh belt and a transmission device. The running speed of the mesh belt is adjusted by a frequency converter and equipped with a digital display mesh belt speed measuring device, which can directly read the mesh belt speed. The temperature control system consists of thermocouples, a digital display intelligent PID controller, and a silicon controlled rectifier, forming a closed-loop control system that can achieve automatic and precise temperature control.

[0003] Currently, the inlet and outlet conveyor belt lengths of various high-temperature mesh belt furnaces on the market are generally short, which cannot meet the needs of all customers. If the inlet mesh belt is too short, less material will be fed in, resulting in excessively long waiting times for manual labor. If the outlet mesh belt is too short, frequent material collection is required, increasing the workload of operators and reducing employee efficiency. Existing mesh belt extension conveyors on the market have unstable conveying and unstable structures, which can easily lead to the risk of workpieces or materials scattering. In addition, various mesh belt furnaces lack alarm functions for isolating upper and lower batches of workpieces or materials to prevent mixing of materials. This paper is aimed at various manufacturing plants that need to appropriately extend the inlet and outlet conveyor belts of their original mesh belt furnaces.

[0004] Therefore, we propose a conveying device suitable for extending mesh belt furnaces and preventing material mixing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a conveying device suitable for extending mesh belt furnaces and preventing material mixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A conveying device suitable for extending and preventing mixing of materials in a mesh belt furnace includes a machine frame, a conveyor belt body is provided on the top of the machine frame, an anti-mixing component is provided on one side of the conveyor belt body, and a conveyor belt support plate is provided on the inner side of the conveyor belt body.

[0008] As a further embodiment of this utility model: a transmission reduction motor is fixedly installed at the bottom of the conveyor belt body, and a motor speed regulator is fixedly installed at the bottom of the conveyor belt body.

[0009] As a further embodiment of this utility model: a transmission chain is provided on the outside of the transmission reduction motor, the transmission end of the transmission reduction motor is fixedly connected to a gear, and the gear is meshed with the transmission chain.

[0010] As a further embodiment of this utility model: a non-powered roller is provided on one side of the conveyor belt body, a conveyor belt drive shaft is provided on the inner side of the conveyor belt body near the non-powered roller, and a conveyor belt tensioning shaft is provided on the inner side of the conveyor belt body away from the conveyor belt drive shaft.

[0011] As a further embodiment of this utility model: a material receiving sensor is fixedly installed on the top of the conveyor belt body, a material receiving alarm is fixedly installed above the conveyor belt tensioning shaft, and an electrical control box is fixedly installed on the inner side of the machine frame. As a further embodiment of this utility model: a "current batch enters furnace" button is installed above the non-powered roller, a "previous batch collected" button is installed above the non-powered roller, and anti-slip feet are fixedly installed at the bottom of the machine frame.

[0012] Compared with the prior art, this utility model provides a conveying device suitable for extending mesh belt furnaces and preventing material mixing, which has the following beneficial effects:

[0013] 1. This utility model, by installing an anti-mixing component, changes the speed of the transmission reduction motor by adjusting the motor speed controller, and drives the conveyor belt drive shaft to rotate via the transmission chain and gears, so that the conveyor belt speed is close to the speed of the mesh belt at the previous station. The workpiece is transmitted from the mesh belt to the conveyor belt via a non-powered roller. When the workpiece is completely conveyed to the position of the receiving sensor, the receiving alarm will sound an audible and visual alarm, and the operator will come to collect the material. After the conveyor belt has been used for a period of time, the tension of the conveyor belt can be adjusted by adjusting the conveyor belt tensioning shaft to ensure that there is no slippage. At the inlet end of the mesh belt furnace, when the first workpiece or material of a batch enters the furnace, a workpiece with an isolation mark is placed and the batch entry button is pressed. When the batch of workpieces or materials exits the furnace, it indicates that the previous batch has been completely removed. At this time, the receiving alarm will continue to sound an alarm. The receiving alarm will stop sounding and visually when the operator completely removes the previous batch of materials or workpieces and presses the previous batch collection button.

[0014] 2. This utility model can smoothly convey workpieces or materials output from a mesh belt furnace. It can be equipped with an alarm function to prevent materials from reaching a designated position according to the factory's own needs, and can also add alarm functions to prevent mixing of workpieces or materials from the previous and next batches. The structure is simple and easy to implement, the structure is robust and reliable, the performance is stable, it is not prone to failure, it is low-cost, easy to maintain and manage, and reduces product quality risks.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

The workpiece is transmitted from the mesh belt to the conveyor belt via the unpowered roller 8. When the workpiece is completely conveyed to the position of the receiving sensor 11, the receiving alarm 12 will trigger an audible and visual alarm, prompting the operator to collect the material.
