Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, specifically to a feeding device for a carbonization furnace. Background Technology

[0002] In the production of materials such as cemented carbide, it is usually necessary to load the prepared raw materials into a boat and place it in equipment such as a carburizing furnace for carbonization. For example, tungsten carbide powder, the main raw material for producing cemented carbide, is generally made by mixing metallic tungsten powder and carbon black in a certain proportion. The mixture is then loaded into a boat and placed in equipment such as a carburizing furnace for carbonization at a certain temperature. After that, it is ball-milled and sieved to obtain tungsten carbide powder. In the existing technology, after the material is loaded into the boat manually or by a loading device, the boat is covered manually and then manually transported to the inlet of the carburizing furnace to be fed into the furnace. This has the problems of low automation, high labor intensity, high cost, and low efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a feeding device for carbonization furnace that can improve the degree of automation, reduce the intensity of manual labor, reduce costs and improve efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A feeding device for a carbonization furnace includes a boat feeding assembly for conveying a boat, a lid supply assembly for supplying a lid, and a lid-covering assembly for covering the boat on the boat feeding assembly. The lid-covering assembly includes a lid-covering drive mechanism and a lid-removing mechanism for removing and placing the lid. The lid-covering drive mechanism is connected to the lid-removing mechanism and can drive the lid-removing mechanism to move so as to remove the lid from the lid supply assembly and cover the boat on the boat feeding assembly.

[0006] As a further improvement to the above technical solution:

[0007] The lid-driving mechanism includes a lifting and moving module and a horizontal moving module for driving the lifting and moving module to move horizontally between the lid-supplying component and the boat-feeding component. The lifting and moving module is connected to the lid-picking and placing mechanism and can drive the lid-picking and placing mechanism to move up and down.

[0008] The horizontal moving module includes a horizontally sliding horizontal moving seat and a first telescopic drive member for driving the horizontal moving seat to move horizontally back and forth. The lifting moving module includes a second telescopic drive member installed on the horizontal moving seat. The driving end of the second telescopic drive member is connected to the cover picking and placing mechanism. The cover picking and placing mechanism is a vacuum suction cup type robot.

[0009] The feeding device for the carbonization furnace also includes a boat discharge component for feeding the boat feeding assembly onto the boat dish.

[0010] The boat feeding assembly is connected to a discharge platform at its outlet end. The boat discharge assembly includes a pusher and a pusher drive. The pusher drive is connected to the pusher and can drive the pusher to reciprocate and translate to push the boat on the discharge platform out of the discharge platform.

[0011] The boat feeding assembly includes a sliding guide mechanism for carrying the boats and enabling the boats to slide from the feed end to the discharge end of the boat feeding assembly, and a sliding drive mechanism for driving all the boats on the sliding guide mechanism to slide synchronously in an intermittent motion.

[0012] The sliding drive mechanism includes a lifting seat that moves up and down driven by a lifting drive component and a translation rod installed in a reciprocating translational motion. The lifting seat is connected to the translation rod and can drive the translation rod to reciprocate between a first height and a second height. At the first height, the translation rod lifts all the boats on the sliding guide mechanism. At the second height, the translation rod places the lifted boats on the sliding guide mechanism. The translation rod is provided with multiple protruding pushers, which are arranged sequentially at intervals in the guiding direction of the sliding guide mechanism. The translation rod is connected to a translation drive component for driving the translation rod to reciprocate translational motion.

[0013] The feeding device for the carbonization furnace also includes a cover assembly. The cover assembly and the cover assembly are arranged sequentially along the direction in which the boat is conveyed by the boat feeding assembly. The cover assembly includes a pressure cap fixedly disposed above the sliding guide mechanism and a lifting mechanism for driving a single boat on the sliding guide mechanism to reciprocate between a third height and a fourth height. The lifting mechanism causes the boat to cooperate with the pressure cap to clamp the boat and the cover when the boat is at the third height so that the cover is completely covered by the boat. The lifting mechanism causes the boat to be placed on the sliding guide mechanism when the boat is at the fourth height.

[0014] The lifting mechanism includes a lifting component for supporting the boat and a lifting drive component that is fixedly installed. The lifting drive component is connected to the lifting component and can drive the lifting component to move up and down.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 2 to 5As shown, the feeding device for a carbonization furnace in this embodiment includes a boat feeding assembly 1 for conveying boats, a lid supply assembly 2 for supplying lids, and a lid-covering assembly 3 for covering the boats on the boat feeding assembly 1. The lid-covering assembly 3 includes a lid-covering drive mechanism 32 and a lid-removing mechanism 31 for removing and placing lids. The lid-covering drive mechanism 32 is connected to the lid-removing mechanism 31 and can drive the lid-removing mechanism 31 to move, so as to remove the lid from the lid supply assembly 2 and cover it on the boat on the boat feeding assembly 1. This feeding device for a carbonization furnace can automatically convey boats filled with materials to the carbonization furnace through the boat feeding assembly 1. During the conveying of the boats along the boat feeding assembly 1, the lid from the lid supply assembly 2 can be removed by the lid-covering assembly 3 and covered on the boat on the boat feeding assembly 1, completing the automatic lid-covering operation of the boats. This can improve the degree of automation, reduce manual labor intensity, reduce costs, and improve efficiency.

[0027] In this embodiment, the cap-driving mechanism 32 includes a lifting and moving module and a horizontal moving module for driving the lifting and moving module to move horizontally between the cap-supplying assembly 2 and the boat-feeding assembly 1. The lifting and moving module is connected to the cap-taking and placing mechanism 31 and can drive the cap-taking and placing mechanism 31 to move up and down. The horizontal moving module drives the lifting and moving module to move the cap-taking and placing mechanism 31 horizontally above the cap-supplying assembly 2. By using the lifting and moving module to drive the cap-taking and placing mechanism 31 to move up and down, the cap on the cap-supplying assembly 2 can be removed. Then, by using the horizontal moving module to drive the lifting and moving module to move the cap-taking and placing mechanism 31 horizontally above the boat-feeding assembly 1, the cap can be placed on the boat on the boat-feeding assembly 1. The cap-driving mechanism 32 adopts a combined structure of the lifting and moving module and the horizontal moving module. Its structure is simple and compact, and its cost is low. The cap-taking and placing mechanism 31 only performs horizontal movement and up and down movement to realize cap taking and cap putting. Its action path is simple, control is convenient, and it is easy to ensure accuracy and stable and reliable operation.

[0028] In this embodiment, the cover supply component 2 preferably adopts a belt conveyor, which facilitates the continuous supply of covers one by one, and also facilitates connection with other workstation equipment to receive covers output by other workstation equipment.

[0029] In this embodiment, the horizontal moving module includes a horizontally sliding horizontal moving seat 321 and a first telescopic drive member 322 for driving the horizontal moving seat 321 to move horizontally reciprocally. The lifting moving module includes a second telescopic drive member 323 mounted on the horizontal moving seat 321, and the driving end of the second telescopic drive member 323 is connected to the cap-taking and placing mechanism 31. The cap-taking and placing mechanism 31 is a vacuum suction cup type manipulator. This type of horizontal moving module and lifting moving module has a simple structure, low cost, and is easy to control. The first telescopic drive member 322 and the second telescopic drive member 323 are preferably telescopic cylinders, but telescopic hydraulic cylinders or electric push rods can also be used. In other embodiments, the horizontal moving module and the lifting moving module can also adopt other existing structural forms, as long as they can drive the cap-taking and placing mechanism 31 to take the cap from the cap supply assembly 2 and place the cap on the boat on the boat delivery assembly 1.

[0030] In this embodiment, the feeding device for the carbonization furnace further includes an unloading component 4 for feeding the boat dish onto the boat feeding assembly 1. The unloading component 4 automatically feeds the boat dish from the boat feeding assembly 1 so that it can dock with the carbonization furnace and be fed into it. Preferably, the direction in which the unloading component 4 feeds the boat dish is perpendicular to the direction in which the boat feeding assembly 1 conveys the boat dish, allowing the carbonization furnace to be arranged on one side of the boat feeding assembly 1, thus reducing the space occupied by the equipment.

[0031] In this embodiment, the outlet end of the boat feeding assembly 1 is connected to the discharge platform 10. The boat discharging assembly 4 includes a pusher (not shown in the figure) and a pusher drive 41. The pusher drive 41 is connected to the pusher and can drive the pusher to reciprocate and translate to push the boat on the discharge platform 10 out of the discharge platform 10. The discharge platform 10 receives the boat output by the boat feeding assembly 1. The pusher drive 41 drives the pusher to reciprocate and translate, which can push the boat on the discharge platform 10 out. The combination of the discharge platform 10, the pusher drive 41 and the pusher facilitates stable and reliable output of the boat. Moreover, the boat discharging assembly 4 and the boat feeding assembly 1 do not interfere with each other, which helps to ensure production cycle efficiency.

[0032] In this embodiment, as Figure 5 As shown, the boat feeding assembly 1 includes a sliding guide mechanism 11 for supporting the boat and allowing it to slide along the feed end to the discharge end of the boat feeding assembly 1, and a sliding drive mechanism 12 for driving all the boats on the sliding guide mechanism 11 to slide synchronously in an intermittent motion. In this embodiment, the sliding guide mechanism 11 is a guide groove that can hold the boat and allow it to slide linearly on it, and is preferably composed of two spaced L-shaped guide rails.

[0033] In this embodiment, as Figure 2 , Figure 3 and Figure 5As shown, the sliding drive mechanism 12 includes a lifting seat 121 driven up and down by a lifting drive member 122 and a translation rod 123 installed in a reciprocating translational motion. The lifting seat 121 is connected to the translation rod 123 and can drive the translation rod 123 to reciprocate between a first height and a second height. At the first height, the translation rod 123 lifts all the boats on the sliding guide mechanism 11. At the second height, the translation rod 123 places the lifted boats on the sliding guide mechanism 11. The translation rod 123 is provided with a plurality of protruding push members 124. The plurality of push members 124 are arranged in sequence and evenly spaced in the guiding direction of the sliding guide mechanism 11. The translation rod 123 is connected to a translation drive member 125 for driving the translation rod 123 to reciprocate translational motion. During operation, when a vessel enters the sliding drive mechanism 12, the lifting drive component 122 drives the lifting seat 121 upward until the height of the pushing component 124 is higher than the supporting surface of the vessel in the sliding drive mechanism 12. Then, the translation drive component 125 drives the translation rod 123 to move towards the discharge end of the sliding drive mechanism 12, pushing the vessel a preset distance towards the discharge end of the sliding drive mechanism 12. Then, the lifting seat 121 is lowered to its original position, and the translation rod 123 is moved back to its original position towards the feed end of the sliding drive mechanism 12. After the next vessel enters the sliding drive mechanism 12, the above process is repeated, so that the next vessel and all the vessels that have entered the sliding drive mechanism 12 are simultaneously pushed a preset distance towards the discharge end of the sliding drive mechanism 12. Finally, the vessels that enter the sliding drive mechanism 12 one by one are moved to the discharge end of the sliding drive mechanism 12. The combination of the sliding drive mechanism 12 and the sliding guide mechanism 11 provides high stability, reliability, and accuracy in conveying the vessel, while also being simple in structure and low in cost. The lifting drive component 122 uses a telescopic cylinder or a telescopic hydraulic cylinder, which avoids the problem of powder combustion due to leakage compared to electric drive components.

[0034] Preferably, the lifting seat 121 is provided with supporting rollers for supporting the translation rod 123. A guide mechanism is provided between the translation rod 123 and the frame of the feeding device. The guide mechanism includes a guide groove provided on the translation rod 123 and a guide plate provided on the frame. The guide plate is inserted into the guide groove, so that the translation rod 123 can move within the first height and the second height range while also performing horizontal reciprocating translational movement. This structure has the advantages of simple structure, easy assembly, and high stability and reliability.

[0035] In this embodiment, the feeding device for the carbonization furnace also includes a cover assembly 5. The cover assembly 3 and the cover assembly 5 are arranged sequentially along the direction of conveying the boat dish in the boat feeding assembly 1. The cover assembly 5 includes a pressure cover 51 fixedly disposed above the sliding guide mechanism 11 and a lifting mechanism for driving a single boat dish on the sliding guide mechanism 11 to reciprocate between a third height and a fourth height. The lifting mechanism causes the boat dish to cooperate with the pressure cover 51 to clamp the boat dish and the cover so that the cover is completely covered in the boat dish when the boat dish is at the third height. The lifting mechanism causes the boat dish to be placed on the sliding guide mechanism 11 when the boat dish is at the fourth height. When there is an interlocking structure between the lid and the boat / dish, due to manufacturing and assembly errors, the lid may not be fully inserted into the boat / dish when the lid is placed on it by the lid-driving mechanism 32. For example, if the lid has a lip structure for inserting into the boat / dish, the angle of the lid may deviate after the lid-driving mechanism 32 places it on the boat / dish, causing the lip structure to rest on the edge of the opening of the boat / dish or not to be fully inserted into the opening. In this case, the lid-driving mechanism 32 should not be used to forcefully press down on the lid, otherwise the lid and the boat / dish may be damaged. However, by setting up an independent lid assembly 5, after the lid-driving mechanism 32 places the lid on the boat / dish, when the boat / dish moves to the position of the lid assembly 5, the lifting mechanism lifts the boat / dish. During the process of the boat / dish rising, the lid on the boat / dish will first contact the pressing member 51. As the boat / dish is further lifted, under the clamping force of the pressing member 51 and the boat / dish, the lid can adaptively adjust its angle relative to the pressing member 51 within a certain range, thereby allowing the lid to be fully inserted into the boat / dish. The complete lid assembly 5 can not only completely cover the boat, but also has the advantages of simple and compact structure, low cost, convenient control, and stable and reliable operation.

[0036] In this embodiment, the lifting mechanism includes a lifting member 52 for supporting the boat and a fixedly installed lifting drive member 53. The lifting drive member 53 is connected to the lifting member 52 and can drive the lifting member 52 to move up and down. When each boat moves along the sliding guide mechanism 11 to the position of the lifting member 52, the lifting drive member 53 drives the lifting member 52 to rise, raising the boat to a third height. This allows it to cooperate with the capping member 51 to clamp the boat and the cap so that the cap is completely inside the boat. After the cap is completely inside the boat, the lifting drive member 53 drives the lifting member 52 to descend, supporting the boat as it moves downward, so that the boat is supported again on the sliding guide mechanism 11, allowing the boat to continue to be transported. This lifting mechanism has a simple and compact structure, low cost, and is easy to control. In this embodiment, the lifting drive member 53 is preferably a telescopic drive member, such as a telescopic hydraulic cylinder, a telescopic pneumatic cylinder, or an electric push rod. Other existing mechanisms can also be used, as long as they can achieve the desired result.

[0037] In this embodiment, as Figure 1As shown, the feeding device for the carbonization furnace also includes a sealing shell 6 that covers and seals the boat container on the boat feeding assembly 1. The sealing shell 6 has an inlet 61 for the boat container to enter the boat feeding assembly 1, an outlet 62 for the boat container to be discharged from the boat feeding assembly 1 by the boat discharge assembly 4, and a cover inlet / outlet 63 for the cover assembly 3 to enter and exit. The inlet 61 has a first opening / closing gate 611, the outlet 62 has a second opening / closing gate 621, and the cover inlet / outlet 63 has a third opening / closing gate 631. The sealing shell 6 can meet the requirements of the conveying environment where the atmosphere is critical. The first opening / closing gate 611, the second opening / closing gate 621, and the third opening / closing gate 631 can be based on existing conventional technology, preferably using a combination of a telescopic drive and a gate. The telescopic drive drives the gate to reciprocate linearly to open and close each port.

[0038] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
