Description

Technical Field

[0001] The invention relates to the technical field of nuclear industry, in particular to an automatic pressing, joining and collecting device for nuclear industry material plates. Background Art

[0002] As a clean and efficient energy source, nuclear energy is widely used in power generation, medical treatment, scientific research and other fields. However, nuclear energy equipment, especially nuclear material plates, are usually in plate form. In order to ensure their performance in experimental research and industrial processing, vapor deposition technology (physical vapor deposition PVD) is usually used to evaporate and coat the material plates. The purpose is to remove moisture and enhance the bonding strength of the film substrate. Heating the substrate under high vacuum can desorb the gas adsorbed on the surface of the substrate.

[0003] During the heating reaction, the material sheet is relatively soft and is easily deformed and difficult to adhere to when in contact with the heating body. During the heating reaction process, if the material sheet does not fully contact the heating body, the performance of the thin film deposited on the target workpiece will be poor, thereby reducing the processing quality of the target workpiece and affecting the use conditions of subsequent processing;

[0004] At the same time, when the heating reaction occurs, the temperature rises gradually. If the temperature or conditions for sufficient reaction are not reached, some waste impurities or loosely bonded powder will be generated and fall off the material plate. If they are not collected, the powder or impurities will fall on other components below, which will affect the life and use requirements of the devices below. Therefore, we propose an automatic pressing and collecting device for nuclear industry material plates.

[0005] German patent publication DE102013002407B3 discloses a method and apparatus for recovering raw materials from a multilayer composite material having at least one layer with a sticky surface. This method and apparatus can be used to manufacture printing plates for printing media used in the printing industry, obtaining sufficiently pure recycled materials. The method involves deep freezing the composite material to be processed (preferably using liquid nitrogen (N2)), then grinding and sieving it in a frozen state to remove any fine particles or dust as destructive components and collecting them. For possible recycling, the remaining material is irradiated with ultraviolet light to achieve complete polymerization, and then fed into a classifier, from which the covering film particles are removed and collected as other parts and reusable raw materials (PET). The remaining material may consist only of the material of the original intermediate layer and may be removed as reusable raw materials (SBS) under further ultraviolet light. However, this method and apparatus for recovering raw materials from a multilayer composite material having at least one layer with a sticky surface uses a freeze-grinding method, which cannot operate stably in the high-temperature environment of the nuclear industry and lacks a reciprocating motion mechanism.

[0006] In order to solve the above-mentioned deficiencies in the prior art, it is worthwhile to provide an automatic pressing and gathering device for nuclear industry material plates. Summary of the Invention

[0007] The purpose of the present invention is to overcome the shortcomings of insufficient adhesion and easy falling of powder when the material plate is heated, and to provide an automatic pressing and collecting device for nuclear industry material plates, which realizes the technical effect of automatically pressing and receiving the falling powder.

[0008] The purpose of the present invention is achieved through the following technical solutions:

The driving shaft and the driven shaft are fixedly connected to a sprocket, and the driving shaft and the driven shaft are connected through a sprocket and a chain.

[0012] Tensioning grooves are provided at the four corners of the assembly slot of the tooling, and a bolt is threadedly connected to one side of the inner wall of the tensioning groove. One end of the bolt is located outside the tensioning groove, and the other end of the bolt is rotatably connected to a tensioning block. The tensioning block and the tensioning groove are both trapezoidal, and the shape of the tensioning block is adapted to the shape of the tensioning groove. The tooling clamps and fixes the nuclear industry material plate through the tensioning block;

[0013] The opening shape of the tooling is adapted to the shape of the nuclear industry material plate. The top and bottom of the opening of the tooling are both in an open state. The tensioning block moves to limit the nuclear industry material plate, thereby achieving clamping and fixing of the nuclear industry material plate.

[0014] The lifting and extrusion mechanism includes a lifting plate vertically slidably connected to both sides of the fixing frame, a lifting shaft rotatably connected to both sides of the fixing frame, and a plurality of lead screws threadedly connected to the lifting plate;

[0015] A first bevel gear set that meshes with each other is provided between one end of the lifting shaft and the end of the driven shaft, and the lifting shaft and the driven shaft are connected through the first bevel gear set. A second bevel gear set is provided between the lifting shaft and the lead screw, and the lifting shaft and the lead screw are connected through the second bevel gear set. The lead screws are rotatably connected to the fixed frame respectively to control the lifting plate to rise or fall, lift up the nuclear industry material plate on the tooling, effectively make the nuclear industry material plate fit with the heating body, and achieve a complete heating reaction.

[0016] A plurality of compression springs are fixedly connected to the top of the lifting plate, and the tooling is located above the compression springs. The compression amount of the compression springs is controlled to determine the lifting force, thereby preventing the nuclear industry material plate from lifting the entire heating body during the lifting process.

[0017] The conveying mechanism includes several conveying wheels rotatably connected to both sides of the fixed frame, the conveying wheels are located on the inner side of the lifting and extrusion mechanism, sprockets are provided on the conveying wheels and the driving shaft, the conveying wheels and the driving shaft are connected through sprockets and chain transmission, the conveying wheels are located below the tooling, and transport the tooling and nuclear industry material plates, thereby realizing automatic loading and unloading and movement of nuclear industry material plates.

[0018] The material splicing mechanism comprises a splicing cloth reel fixedly connected to the driving shaft, a cloth pulling rod fixedly connected to the driving shaft and the driven shaft transmission chain, and a splicing cloth arranged between the splicing cloth reel and the cloth pulling rod.

[0019] One end of the splicing cloth is wound around the outside of the splicing cloth reel, and the other end of the splicing cloth is fixedly connected to the cloth pulling rod. The splicing cloth is located between the tooling and the evaporation device. The splicing cloth is rolled up by the splicing cloth reel, thereby realizing the reciprocating movement of the splicing cloth, and concentrating the nuclear industry powder and impurities carried on the splicing cloth and transferring them to the cleaning mechanism.

[0020] The material splicing mechanism also includes a splicing cloth guide rail fixedly connected to the fixed frame, and a splicing cloth cross brace fixedly connected between the splicing cloth guide rails;

[0021] The splicing cloth guide rail and the splicing cloth cross brace are both located below the splicing cloth. The splicing cloth guide rail is a double-row groove rail. The splicing cloth cross brace is equidistantly installed on the inner groove rail of the splicing cloth guide rail. The splicing cloth guide rail and the splicing cloth cross brace support the splicing cloth to prevent it from drooping, which is suitable for situations where the splicing cloth is longer.

[0023] The bottom of the collection box is an inclined surface, and a torsion spring is sleeved on the connecting shaft between the connecting block and the collection box. The torsion of the torsion spring makes the cleaning cloth fit into the surface of the material receiving mechanism. The collection box is located below one end of the material receiving mechanism to prevent nuclear industrial waste attached to the material receiving cloth from falling into the evaporation device and damaging it due to insufficient cleaning.

[0024] The material of the splicing cloth is ceramic fiber cloth, and the material of the cleaning cloth is ceramic fiber blanket. The splicing cloth and cleaning cloth made of ceramic fiber material can continue to work at a high temperature of 600 degrees.

DETAILED DESCRIPTION

[0039] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0040] Example 1

[0041] like Figures 1 to 9 As shown, the automatic pressing, splicing and collecting device for nuclear industry material plates includes a protective shell 1, a fixed frame arranged inside the protective shell 1, a plurality of heating bodies 2 arranged on the top of the fixed frame, and an evaporation device 3 arranged at the bottom of the fixed frame. It is characterized by: further including a lifting and extruding mechanism 4 arranged on both sides of the fixed frame, a conveying mechanism 5 arranged inside the lifting and extruding mechanism, a material receiving mechanism 6 arranged inside the conveying mechanism 5, and a cleaning mechanism 7 arranged below one end of the material receiving mechanism 6;

[0042] A tooling 8 is provided above the lifting and extrusion mechanism 4, and a nuclear industry material plate 9 is mounted on the tooling 8;

[0043] A plurality of drive motors 10 are provided on one side of the protective shell 1. The drive motors 10 are connected to a driving shaft 11 through a worm gear and a universal joint. The driving shaft 11 is rotatably connected to one end of the fixed frame, and the other end of the fixed frame is rotatably connected to a plurality of driven shafts 12. Sprockets are fixedly connected to the driving shaft 11 and the driven shaft 12, and the driving shaft 11 and the driven shaft 12 are connected through a sprocket and a chain transmission.

[0044] like Figures 2 to 3 As shown, tensioning grooves 801 are provided at the four corners of the assembly groove of the tool 8. A bolt 802 is threadedly connected to one side of the inner wall of the tensioning groove 801. One end of the bolt 802 is located outside the tensioning groove 801. The other end of the bolt 802 is rotatably connected to a tensioning block 803. The tensioning block 803 and the tensioning groove 801 are both trapezoidal. The shape of the tensioning block 803 matches the shape of the tensioning groove 801. The tool 8 clamps and fixes the nuclear industry material plate 9 through the tensioning block 803.

[0045] The opening shape of the tooling 8 is adapted to the shape of the nuclear industry material plate 9, and the top and bottom of the opening of the tooling 8 are both in an open state. By setting a tensioning block 803 on the tooling 8, the nuclear industry material plate 9 is placed in the opening of the tooling 8, and the bolt 802 outside the tensioning groove 801 is rotated to move the tensioning block 803 to limit the nuclear industry material plate 9, so that the nuclear industry material plate 9 can be clamped and fixed, and the tightness of the nuclear industry material plate 9 can be adjusted as needed to facilitate full contact with the heating body 2, while ensuring the stable state of lifting and heating. The bottom of the opening of the tooling 8 is set to an open state, so that the evaporation device 3 can steam heat the nuclear industry material plate, and at the same time it is convenient for the material receiving mechanism 6 to receive and collect the powder generated during the heating process of the nuclear industry material plate.

[0046] like Figures 4 to 6 As shown, the lifting and squeezing mechanism 4 includes a lifting plate 401 vertically slidably connected to both sides of the fixing frame, a lifting shaft 402 rotatably connected to both sides of the fixing frame, and a plurality of lead screws 403 threadedly connected to the lifting plate 401;

[0047] A first bevel gear set 404 meshing with each other is provided between one end of the lifting shaft 402 and the end of the driven shaft 12, and the lifting shaft 402 and the driven shaft 12 are connected by the first bevel gear set 404. A second bevel gear set 405 is provided between the lifting shaft 402 and the lead screw 403, and the lifting shaft 402 and the lead screw 403 are connected by the second bevel gear set 405. The lead screw 403 is rotatably connected to the fixed frame. By arranging liftable lifting plates 401 on both sides of the device, during operation, the driving motor 10 drives The driving shaft 11 rotates, and the sprocket drives the driving shaft 11 to drive the driven shaft 12 to rotate. The first bevel gear set 404 drives the lifting shafts 402 on both sides to rotate respectively, and the second bevel gear set 405 drives the lead screw 403 to rotate. Under the cooperation of the thread of the lead screw 403 and the lifting plate 401, the torsional force is converted into a vertical force, thereby controlling the lifting plate 401 to rise or fall, and lifting the nuclear industry material plate 9 on the tooling 8, effectively making the nuclear industry material plate 9 fit with the heating body 2, and achieving a complete heating reaction;

[0048] Furthermore, since the lifting shafts 402 on both sides are driven to rotate by the same driven shaft 12, the rotation directions of the two lifting shafts 402 are opposite, so that the thread directions of the lead screws 403 on both sides and the lifting plates 401 are opposite, so that the lifting plates 401 on both sides can be lifted and lowered synchronously when the lifting shafts 402 are in opposite directions.

[0049] like Figures 4 to 8 As shown, a number of compression springs 406 are fixedly connected to the top of the lifting plate 401, and the tooling 8 is located above the compression springs 406. By arranging the compression springs 406 between the lifting plate 401 and the tooling 8, the compression amount of the compression springs 406 is controlled to determine the lifting force, thereby preventing the nuclear industry material plate 9 from lifting the heating body 2 as a whole during the lifting process, causing it to fall, and can also play a buffering role, making the contact process between the nuclear industry material plate 9 and the heating body 2 more gentle and smooth.

[0050] Example 2

[0051] like Figures 4 to 8 As shown, the conveying mechanism 5 includes several conveying wheels 501 rotatably connected to both sides of the fixed frame, the conveying wheels 501 are located on the inner side of the lifting and extruding mechanism 4, and sprockets are provided on the conveying wheels 501 and the driving shaft 11. The conveying wheels 501 and the driving shaft 11 are connected through sprockets and chain transmission. The conveying wheel 501 is located below the tooling 8, and is driven to rotate by the driving shaft 1 and the chain sprocket transmission, thereby conveying the tooling 8 and the nuclear industry material plate 9, thereby realizing automatic loading and unloading and movement of the nuclear industry material plate 9.

[0052] Example 3

[0053] like Figures 4 to 6 As shown, the material splicing mechanism 6 includes a splicing cloth reel 601 fixedly connected to the driving shaft 11, a cloth pulling rod 602 fixedly connected to the driving shaft 11 and the driven shaft 12 transmission chain, and a splicing cloth 603 arranged between the splicing cloth reel 601 and the cloth pulling rod 602.

[0054] like Figures 4 to 6As shown, one end of the splicing cloth 603 is wound around the outside of the splicing cloth reel 601, and the other end of the splicing cloth 603 is fixedly connected to the cloth pulling rod 602. The splicing cloth 603 is located between the tooling 8 and the evaporation device 3. By arranging the splicing cloth 603 between the splicing cloth 603 and the nuclear industry material plate 9, the powder or impurities generated by the nuclear industry material plate 9 are continuously spliced and collected. When stretched, the cloth pulling rod 602 follows the movement of the above-mentioned chain (the cloth pulling rod 602 is clamped on the outside of the chain, thereby being able to directly The connecting cloth 603 is pulled out when the cloth is retracted, and since the cloth pulling rod 602 is mounted on the chain, the connecting cloth 603 can be rolled up by the connecting cloth reel 601 when the chain is retracted, thereby realizing the reciprocating movement of the connecting cloth 603, and collecting the nuclear industry powder and impurities carried by the connecting cloth 603 and transferring them to the cleaning mechanism. The setting positions of the rotating shaft 11 and the driven shaft 12 are both far away from the two ends of the material plate, so the connecting cloth 603 can receive the material falling off in the entire area of the material plate.

[0055] like Figures 7 and 8 As shown, the material splicing mechanism 6 further includes a splicing cloth guide rail 604 fixedly connected to the fixed frame, and a splicing cloth cross brace 605 fixedly connected between the splicing cloth guide rail 604;

[0056] The splicing cloth guide rail 604 and the splicing cloth cross brace 605 are both located below the splicing cloth 603. The splicing cloth guide rail 604 is a double-row groove rail. The splicing cloth cross brace 605 is installed equidistantly on the inner groove rail of the splicing cloth guide rail 604. By arranging the splicing cloth guide rail 604 and the splicing cloth cross brace 605 below the splicing cloth 603, the splicing cloth 603 is supported to prevent it from drooping, which is suitable for the case where the splicing cloth 603 is long.

[0057] Furthermore, the inner groove of the splicing cloth guide rail 604 is used to install the splicing cloth cross brace 605, and the outer groove is used to place the chain between the driving shaft 11 and the driven shaft 12, and the cloth pulling rod 602 is clamped on the chain through a clamping structure.

[0058] Example 4

[0059] like Figures 2 to 9 As shown, the cleaning mechanism 7 includes a material collecting box 701 fixedly connected to one side of the fixing frame, a connecting block 702 rotatably connected to one side of the top of the material collecting box 701, and a cleaning cloth 703 fixedly connected to the connecting block 702;

[0060] The bottom of the collection box 701 is an inclined surface, and a torsion spring is sleeved on the connecting shaft between the connecting block 702 and the collection box 701. The torsion of the torsion spring makes the cleaning cloth 703 fit into the surface of the material receiving mechanism 6. The collection box 701 is located below one end of the material receiving mechanism 6. By setting the bottom of the collection box 701 to an inclined surface, it is convenient to concentrate the collected nuclear industrial waste, and in the process of the material receiving cloth 603 of the material receiving mechanism 6 moving back and forth, the cleaning cloth 703 maintains a state of fitting and contacting with the material receiving cloth 603, and the nuclear industrial waste attached to the material receiving cloth 603 is cleaned and dropped into the collection box 701 for collection, thereby avoiding the situation where the nuclear industrial waste attached to the material receiving cloth 603 is not fully cleaned and falls into the evaporation device 3 to cause damage to it.

[0061] The material of the splicing cloth 603 is ceramic fiber cloth, and the material of the cleaning cloth 703 is ceramic fiber blanket. The splicing cloth 603 and the cleaning cloth 703 made of ceramic fiber can work continuously at a high temperature of 600 degrees, and have the flexibility to be curled, and can be used for a long time in the working environment of heated material plates in the nuclear industry.
