Description

Mesh belt furnace capable of being driven by hand

Technical Field

The utility model relates to a mesh belt furnace field.

Background

The mesh belt furnace is a device which utilizes mesh belts to convey electronic elements and sends the electronic elements into a hearth for high-temperature sintering. The transmission mechanism of the mesh belt furnace generally drives the mesh belt through the transmission mode of a motor-reduction box-chain wheel-mesh belt, so that the electronic element is conveyed into a hearth for high-temperature sintering. The equipment hearths generally adopt long plate hearths due to process requirements so as to ensure that enough temperature and time are available for sintering the electronic components. When the equipment is shut down in emergency such as power failure, the temperature of the hearth is reduced, so that the electronic elements are insufficiently sintered and the product is poor; meanwhile, when the motor stops working, the mesh belt stays in the hearth and is impacted by high temperature for a long time, and deformation is generated.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model lies in: aiming at the defects in the prior art, the mesh belt furnace which can cope with the emergency situations such as shutdown and the like and avoid insufficient sintering of electronic elements and mesh belt deformation and can be driven by hand is provided.

In order to solve the technical problem, the utility model discloses a following technical scheme:

The utility model provides a mesh belt furnace that can hand drive, includes furnace, guipure conveying mechanism, motor, reducing gear box and drive sprocket, the motor is connected with the reducing gear box, the motor passes through the reducing gear box and is connected with drive sprocket, and drive sprocket drives guipure conveying mechanism operation, and guipure conveying mechanism sends electronic component into furnace and sinters, one side of drive sprocket is equipped with the twist grip, the opposite side of drive sprocket is equipped with the coupling shaft, the coupling shaft is detachable with the output shaft of reducing gear box and is connected, the coupling shaft passes through the bearing and installs on a support seat.

Furthermore, the coupling shaft is connected with the output shaft of the reduction gearbox through a locking screw.

Compared with the prior art, the utility model has the advantages of: the utility model discloses a change the coupling shaft of driving sprocket and the output shaft of reducing gear box into detachable connection, when the mesh belt furnace meets emergency such as having a power failure, can separate the output shaft of coupling shaft and speed reducer, it is rotatory to order about driving sprocket through manual swing twist grip, can drive the guipure conveying mechanism operation equally, carry out furnace with the electronic component on the guipure, thereby avoid stopping furnace temperature because of equipment and descend and lead to the electronic component sintering insufficient, still can avoid the guipure part to stop for a long time simultaneously and receive high temperature impact and warp in furnace.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, and it should be noted that the scope of the present invention is not limited to the following embodiments, and any modifications and decorations made by the present invention should be considered as the scope of the present invention without departing from the principle of the present invention.

as shown in fig. 1 and 2, the utility model discloses a mesh belt furnace capable of being driven by hand, including furnace 1, heating tube 2, mesh belt conveying mechanism, motor 4, reducing gear box 5 and sprocket drive mechanism, heating tube 2 is located furnace 1 for carry out high temperature sintering to the electronic component 7 of sending into furnace 1. The mesh belt conveying mechanism mainly comprises a plurality of rollers 32 and mesh belts 31 wound on the rollers 32. The sprocket transmission mechanism mainly comprises a driving sprocket 61, a driven sprocket 62 and a chain 63, wherein the driven sprocket 62 is fixedly connected with one of the rollers 32. The motor 4 is connected with the reduction gearbox 5 through a belt, an output shaft 51 of the reduction gearbox 5 is connected with a driving chain wheel 61 and used for driving the driving chain wheel 61 to rotate, the driving chain wheel 61 drives a driven chain wheel 62 and the roller 32 to rotate, so that the mesh belt conveying mechanism is driven to operate, and the mesh belt 31 sends the electronic element 7 into the hearth 1 for sintering.

As shown in figure 2, one side of the driving chain wheel 61 is provided with a rotating handle 8, the other side of the driving chain wheel 61 is provided with a connecting shaft 9, the connecting shaft 9 is detachably connected with the output shaft 51 of the reduction gearbox 5, and the connecting shaft 9 is arranged on a supporting seat 10 through a bearing. When the mesh belt furnace encounters emergency such as power failure, the equipment stops, the motor 4 stops working, the connecting shaft 9 can be separated from the output shaft 51 of the speed reducer, the driving chain wheel 61 is driven to rotate by manually shaking the rotating handle 8, the mesh belt 31 conveying mechanism can be driven to run, and the electronic element 7 on the mesh belt 31 is conveyed out of the hearth 1, so that insufficient sintering of the electronic element 7 caused by temperature reduction of the hearth 1 due to equipment stop is avoided, and meanwhile, the mesh belt 31 can be prevented from being deformed due to high-temperature impact when being locally stopped in the hearth 1 for a long time.

In this embodiment, the coupling shaft 9 is connected to the output shaft 51 of the reduction gearbox 5 through the locking screw 11, and the specific connection mode is as follows: a central hole is axially formed in the end part of an output shaft 51 of the reduction gearbox 5, the connecting shaft 9 is inserted into the central hole, meanwhile, threaded through holes are radially formed in corresponding positions of the side walls of the output shaft 51 and the connecting shaft 9, and the locking screw 11 is screwed into the threaded through holes, so that connection is completed. When the output shaft 51 needs to be separated from the coupling shaft 9, the locking screw 11 is screwed out.
