Abstract

The present invention relates to the field of film processing technology, specifically to a graphene film production and processing device, including a drying box, a drying mechanism and an adjustment mechanism. In the present invention, two hinged bars are used to adjust the opening angle between the corresponding two opening plates, so that the corresponding two opening plates cooperate with each other to press against the graphene film. The above method makes the graphene film taut in the drying box and presents a set wavy shape. The above method ensures that the film always remains taut during the drying process, avoiding the problem of film wrinkles and uneven thickness that lead to reduced film quality. At the same time, the wavy shape of the film facilitates the drying mechanism to perform drying operations from the upper and lower ends of the film at the same time, ensuring that the film is dried evenly.

[0002] Graphene films are mainly prepared by mechanical exfoliation, chemical vapor deposition, oxidation-reduction method, solution exfoliation method and electrochemical exfoliation method. In the process of preparing graphene films by solution exfoliation method, graphite is first exfoliated using a solvent and the graphene solution is deposited on a substrate by spin coating, spraying, etc., and then a drying operation is performed to evaporate the solvent to finally obtain the desired product.

[0003] At present, there are two main drying methods: natural drying and oven drying.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a graphene film production and processing device comprises: a drying box 1, the interior of the drying box 1 is a cavity and the left and right sides of the drying box 1 are provided with openings 2, the upper and lower end surfaces of the inner cavity of the drying box 1 are provided with two left and right distributed groove groups, and the two upper groove groups and the two lower groove groups are staggered left and right, and the groove group includes two left and right distributed sliding grooves 3, and sliding blocks 30 are slidably arranged in the sliding grooves 3, and all the sliding blocks 30 are commonly provided with a drying mechanism 4 for drying the graphene film.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the drying mechanism 4 includes a support plate 40, and the sliding block 30 is hinged with a support plate 40 with a cavity inside. The two support plates 40 corresponding to the same slot group are rotated together through a connecting bar and a connecting rod 400 with an axis extending from front to back is arranged, and the opposite back sides of the two support plates 40 corresponding to the same slot group are provided with a plurality of air outlets 401 arranged in a matrix, and the drying box 1 is provided with a wind control unit 41, and the drying box 1 is provided with an adjustment mechanism 5 for controlling the tension of the film by adjusting the opening angle of the support plate 40.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjusting mechanism 5 includes a threaded rod 50, and the upper and lower ends of the drying box 1 are rotatably provided with a threaded rod 50 with a vertical axis and corresponding to the groove group one by one, and the threaded rod 50 is located between the two sliding grooves 3 in the corresponding groove group, and a lifting block 500 is sleeved on the threaded rod 50, and the threaded rod 50 and the corresponding lifting block 500 are threadedly matched, and the lifting block 500 and the corresponding two support plates 40 are hinged by a hinge bar 501, and the adjusting mechanism 5 also includes a driving unit 52 for driving the lifting block 500 to move up and down.

[0032] The staff member brings the graphene film into the inner cavity of the drying box 1 from the left side opening 2 of the drying box 1, bypasses a plurality of support plates 40, so that the graphene film is wavy in the drying box 1, and finally passes through the right side opening 2 of the drying box 1, and is wound on the external existing winding device located on the right side of the drying box 1. It should be noted that the external existing winding device winds the graphene film so that the graphene film moves from left to right in the drying box 1. When working, the driving unit 52 works to make the lifting block 500 in the adjusting mechanism 5 move up and down, thereby The two hinged bars 501 are used to adjust the opening angle between the corresponding two support plates 40, so that the corresponding two support plates 40 cooperate with each other to press against the graphene film. Through the above method, the graphene film is tightened in the drying box 1 and presents the set wave shape. After completing the above adjustment operation, the adjustment mechanism 5 is locked, and then the wind control unit 41 in the drying mechanism 4 works to pump hot air into the inner cavity of all support plates 40, and blow it out to the surface of the film through the outlet 401. Through the cooperation of multiple support plates 40, the hot air is blown to the upper and lower surfaces of the film, and the film is dried.

[0033] What needs to be explained in the above process is that, through the mutual cooperation between different support plates 40 in multiple slot groups, a certain tensioning force is provided for the passing film. Secondly, the two support plates 40 in the same slot group are adjusted to different opening angles through the adjustment mechanism 5, so as to provide appropriate or sufficient tensioning force for the film, avoid the film from becoming loose, wrinkled, and other problems that affect the quality of the final product during the drying process, adapt to the requirements of different thickness sizes and different process conditions, and improve the applicability of the device. After adjusting the opening angle, the adjustment mechanism 5 locks the support plate 40 to improve the stability during the drying process.

[0034] like Figure 2 and Figure 3 As shown, the air control unit 41 includes a connecting pipe 410, and the sliding block 30 and the upper and lower ends of the drying box 1 are located between the two sliding grooves 3 in the same groove group. Both are cavities, and the inner wall of the sliding groove 3 is slidably penetrated with a plurality of connecting pipes 410 arranged from front to back, and the connecting pipe 410 connects the corresponding sliding block 30 inner cavity and the corresponding upper and lower ends of the drying box 1. The inner cavity of the sliding block 30 and the inner cavity of the support plate 40 are connected by a flexible air inlet pipe 411. Two circular tubes 412 are respectively connected to the left cavities at the upper and lower ends of the drying box 1 at the upper and lower ends of the drying box 1. The circular tube 412 is connected to an external air pump. U-shaped tubes 413 are fixedly provided at the upper and lower ends of the drying box 1. A vertical section on one side of the U-shaped tube 413 penetrates between two adjacent support plates 40 in different groove groups in the drying box 1, and a vertical section on the other side of the U-shaped tube 413 is connected to the cavity of the drying box 1 corresponding to the right groove group, and an air pump 414 is provided on the U-shaped tube 413.

[0035] During operation, after the film is placed in the drying box 1 and stretched and tensioned by the support plate 40, the external air pump works to pump hot air into the corresponding cavities in the drying box 1 through the two circular tubes 412. The hot air in the two cavities enters the corresponding cavity of the sliding block 30 through the corresponding connecting tube 410, and then enters the inner cavity of the corresponding support plate 40 through the air inlet pipe 411, and finally blows to the surface of the film through the air outlet 401 on the corresponding support plate 40. It should be noted that the hot air blown out from the lower support plate 40 contacts the lower surface of the film, and the hot air blown out from the upper support plate 40 contacts the upper surface of the film. In the above manner, the upper and lower ends of the film are both exposed to the hot air, and both sides of the film are dried by hot air, thereby improving the drying quality and efficiency.

[0036] The hot air blown out from the support plate 40 stays in the inner cavity of the drying box 1, and part of the hot air blown out from the lower support plate 40 stays under the film, and part of the hot air blown out from the upper support plate 40 stays above the film. The air pump 414 works to extract most of the hot air in the drying box 1 through the left vertical section of the U-shaped tube 413. This part of the hot air re-enters the corresponding cavities on the upper and lower sides of the drying box 1 through the right vertical section of the U-shaped tube 413, and is blown out from the corresponding support plate 40 on the right side to dry the film again. It should be noted that in the above process, the hot air is pumped to the surface of the film twice from left to right, which accelerates the drying rate. The temperature of the hot air decreases from left to right during the transfer process. The temperature of the hot air blown out from the left support plate 40 is higher than the temperature of the hot air blown out from the right support plate 40. Therefore, the temperature of the film itself gradually decreases during the drying process from left to right, that is, the temperature of the film gradually decreases after the drying operation is completed. Slow cooling helps the film to adapt smoothly to changes in ambient temperature, thereby reducing warping or other morphological changes.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, the drying mechanism 4 also includes a propping strip 42, and the connecting rod 400 is fixedly provided with an arc-shaped propping strip 42 through a connecting block, and the connecting rod 400 is located between the propping strip 42 and the corresponding lifting block 500. The connecting rod 400 is fixedly provided with a rectangular plate 420 located between the connecting rod 400 and the lifting block 500 through two front and rear distributed stabilizing strips, and the rectangular plate 420 is used to improve the overall stability.

[0038] like Figure 5 and Figure 6 As shown, the outer arc surface of the expansion strip 42 is away from the corresponding connecting rod 400 , and two front-to-back symmetrical limiting blocks 431 are fixedly disposed on the outer arc surface of the expansion strip 42 .

[0039] like Figure 1 and Figure 2 As shown, the adjustment mechanism 5 also includes a placement groove 51, and the front end surface of the drying box 1 is provided with a wavy placement groove 51 for placing the film into the drying box 1. The front end surface of the drying box 1 is slidably penetrated by sliding columns 510 corresponding to the groove groups one by one and with axes extending from front to back. A moving plate 511 is slidably arranged on all the sliding columns 510. A sealing plate 512 that fits the placement groove 51 is slidably arranged on the moving plate 511 through a connecting column to slide back and forth. A spring 513 sleeved on the connecting column is fixedly arranged between the sealing plate 512 and the moving plate 511. Two left-right distributed stoppers 514 are fixedly arranged on the front end surface of the inner cavity of the drying box 1, and the moving plate 511 is driven by an external hydraulic cylinder (not shown in the figure) to move back and forth.

[0040] like Figure 1 , Figure 3and Figure 4 As shown, the driving unit 52 includes a driving shaft 520, and the upper end surface of the drying box 1 is rotatably provided with a driving shaft 520 with a vertical axis, and the driving shaft 520 and the threaded rod 50 are both fixedly sleeved with a sprocket 1 521 located outside the drying box 1, and the three sprockets 1 521 on the upper side and the two sprockets 1 521 on the lower side are connected by a chain 1, and the rear side of the drying box 1 is rotatably provided with a transmission shaft 522 with a vertical axis, and sprockets 2 523 are fixedly sleeved on both ends of the transmission shaft 522, the driving shaft 520 and the threaded rod 50 on the leftmost side of the lower end, and a chain 2 is commonly arranged between two adjacent sprockets 2 523.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the driving unit 52 also includes a gear 524, the gear 524 is fixedly sleeved on the driving shaft 520, a transverse plate 525 is slidably penetrated through the movable plate 511, an L-shaped rack plate 526 is fixedly provided on the upper end surface of the transverse plate 525, the horizontal section of the rack plate 526 is meshed with the gear 524, and an adjustment group 53 is provided on the transverse plate 525.

[0042] In the initial state, the sealing plate 512 is located at the front side of the drying box 1, so that the staff can pass the film through the inner cavity of the drying box 1 from left to right. During this process, the position of the film can be adjusted by the placement groove 51, so that the film is arranged in a wave shape in the drying box 1, and the film contacts the corresponding expansion strip 42 and is located between the two limit blocks 431 on the same expansion strip 42. After the placement of the film is completed, as the right side of the subsequent film is wound by the external existing winding equipment, the film is in a preliminary taut state, and the front and rear directions of the film are limited by the two limit blocks 431 on the same expansion strip 42 to prevent the film from deviating and affecting the subsequent drying process.

[0043] Afterwards, the external hydraulic cylinder works to move the movable plate 511 backward, and the movable plate 511 drives the connecting column and the sealing plate 512 to move backward synchronously. The sealing plate 512 moves backward until it contacts the corresponding stop block 514 and then stops moving. As the movable plate 511 continues to move, the spring 1 513 is compressed, and the elastic force generated by the compression of the spring 1 513 acts on the sealing plate 512, so that the sealing plate 512 is pressed tightly against the two stop blocks 514, completing the sealing process of the drying box 1, avoiding the overflow of hot air inside the drying box 1 during operation, ensuring the stability of the temperature inside the drying box 1, and thus ensuring the drying quality of the film.

[0044] As the moving plate 511 continues to move, the transverse plate 525 and the rack plate 526 move backward synchronously. Through the meshing between the rack plate 526 and the gear 524, the gear 524 drives the driving shaft 520 to rotate synchronously. The driving shaft 520 drives the two upper threaded rods 50 to rotate synchronously through the cooperation between the upper sprocket wheel 1 521 and the upper chain 1. At the same time, the driving shaft 520 drives the transmission shaft 522 to rotate synchronously through the cooperation between the upper sprocket wheel 2 523 and the upper chain 2. The transmission shaft 522 drives the lower left threaded rod 50 to rotate synchronously through the cooperation between the upper sprocket wheel 2 523 and the lower chain 2. The threaded rod 50 makes the two lower threaded rods 50 rotate synchronously through the cooperation between the sprocket 1 521 and the chain 1 thereon. Therefore, through the threaded cooperation between the threaded rod 50 and its corresponding lifting block 500, the lower lifting block 500 moves down and the upper lifting block 500 moves up. The lifting block 500 drives the hinged bar 501 to move synchronously, so that the corresponding two support plates 40 in the same groove group are opened, the corresponding opening bar 42 in the lower groove group moves up, and the opening bar 42 corresponding to the upper groove group moves down. In this way, the film is tightened, which is convenient for improving the drying quality and avoiding the problem of film warping during the drying process.

[0045] like Figure 1 and Figure 2 As shown, the adjustment group 53 includes adjustment holes 530, and the upper end surface of the transverse plate 525 is provided with a plurality of adjustment holes 530 arranged equidistantly from front to back, and the front end surface of the movable plate 511 is provided with a movable pin 531 that cooperates with the adjustment hole 530 and slides up and down through a lifting bar.

[0046] like Figure 2 , Figure 4 and Figure 5 As shown, a fixing group 54 is arranged on the sliding column 510, and the fixing group 54 includes a vertical plate 540. The rear end face of the sliding column 510 is fixedly provided with the vertical plate 540, and the rear end face of the vertical plate 540 is equidistantly fixedly provided with a plurality of column groups from top to bottom, and the column group includes two left-right symmetrical fixing columns 541. The front end face of the lifting block 500 is provided with two left-right distributed fixing holes 546, and the front side of the inner wall of the fixing hole 546 is chamfered, and the diameter of the fixing hole 546 is larger than the diameter of the fixing column 541.

[0047] like Figure 2 , Figure 4 and Figure 5As shown, the fixed group 54 also includes a fixed circular plate 542, and the sliding column 510 is fixedly provided with a fixed circular plate 542 located between the movable plate 511 and the drying box 1. All the fixed circular plates 542 are fixedly connected together by a connecting frame 543, and a pushing plate 544 for pushing the fixed circular plate 542 is fixedly provided on the transverse plate 525. A spring 545 mounted on the sliding column 510 is fixedly provided between the fixed circular plate 542 and the drying box 1.

[0048] It should be noted that, in the initial state, the pushing plate 544 is located in front of the leftmost fixed circular plate 542 and does not contact the fixed circular plate 542. During the process in which the movable plate 511 moves to make the sealing plate 512 seal the drying box 1, the pushing plate 544 still does not contact the corresponding fixed circular plate 542. During the process in which the two corresponding support plates 40 are stretched apart by the continuous movement of the movable plate 511, the rack plate 526 moves backward to rotate the driving shaft 520. During this process, the pushing plate 544 moves backward to contact the leftmost fixed circular plate 542, and pushes the fixed circular plate 542 and all other fixed circular plates 542 to move backward synchronously. The fixed circular plate 542 moves backward to compress the spring 2 545 and bring The corresponding sliding column 510 moves backward synchronously, and the sliding column 510 brings the vertical plate 540 and the fixed column 541 thereon to move backward synchronously. The fixed hole 546 on the lifting block 500 is gradually aligned with the corresponding fixed column 541 on the vertical plate 540. With the continuous movement of the rack plate 526, the fixed column 541 is inserted into the corresponding fixed hole 546 and finally contacts with the inner wall of the fixed hole 546. The upper and lower positions of the lifting block 500 are fixed by the cooperation between the fixed column 541 and the fixed hole 546. After the rack plate 526 stops moving backward, a stable triangular structure is formed between the corresponding two support plates 40 and the drying box 1, which improves the stability of the support plate 40 when opening the film.

[0049] Before carrying out the drying operation, the distance between the rack plate 526 and the gear 524 in the initial state is adjusted according to the required tensioning degree of the film. Specifically, the lifting bar and the movable latch 531 are manually moved up, and then the transverse plate 525 and the rack plate 526 are moved so that the adjustment hole 530 at the specified position of the rack plate 526 is opposite to the movable latch 531, and then the movable latch 531 is inserted into the adjustment hole 530 to complete the fixation of the transverse plate 525. It should be noted that the adjustment hole 530 on the transverse plate 525 corresponds to the fixed column 541 on the vertical plate 540 one by one, that is, after adjusting the transverse plate 525 and the vertical plate 540 moves up and down, the fixed column 541 corresponding to the adjustment hole 530 with the movable latch 531 inserted on the vertical plate 540 can be accurately inserted into the corresponding fixed hole 546.
