Description

Technical Field

[0001] The invention relates to the technical field of graphite heat exchanger production equipment, and in particular to a destacking device for graphite heat exchanger production. Background Art

[0002] Graphite heat exchanger is a heat exchanger whose heat transfer components are made of graphite. The graphite used to make the heat exchanger should be impermeable. Impregnated impermeable graphite and pressed impermeable graphite are commonly used. Graphite heat exchangers can be divided into three types according to their structure: block hole type, shell and tube type, and plate type. The block hole graphite heat exchanger is assembled from several block graphite components with holes, and multiple graphite components are fixed in the shell;

[0003] The graphite components with holes are stacked up and down when stacking. The specific stacking method is as shown in the figure of the specification. Figure 8 In the state shown in state a, the graphite components need to be moved upwards piece by piece when destacking, but there are some inconveniences when destacking, such as:

[0004] Since the upper graphite component is stacked on top of the lower graphite component, and the gap between the upper and lower graphite components is small, conventional lifting and destacking equipment cannot directly grab the upper graphite component. It is necessary to manually force the hook of the lifting and destacking equipment under the upper graphite component, which is very inconvenient to use. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a destacking device for producing graphite heat exchangers to solve the above problems.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A destacking device for graphite heat exchanger production, comprising a base, a lifter, a general support frame, a transverse top plate and a bracket;

[0008] Main support frame: A power assembly is installed on the upper side of the main support frame, and a linear array of arrangement holes is provided on the side of the main support frame, a limit pin is movably inserted into one of the arrangement holes, and a limiter is installed in one of the arrangement holes;

[0009] Lifter: There are two lifters and both slide transversely in the main support frame, one of which is fixed at the output end of the power assembly, and the power assembly drives the lifter to slide transversely, and the other lifter is located between the limit pin and the limiter, and a telescopic assembly is fixed between the two lifters;

[0010] Horizontal top plate: The horizontal top plate is fixed to the output end of the lifter installed on the output end of the power assembly, and the lifter drives the horizontal top plate to move up and down;

[0011] Card rack: The card rack rotates at the output end of the lifter located between the limit pin and the limiter, and the lifter drives the card rack to move up and down. The card rack and the horizontal top plate are at the same height and correspond to each other on the left and right;

[0012] Base: The base is fixed below the main support frame, a supporting slide is movably inserted in the base along its length direction, a bracket is rotatably provided on the upper side of the supporting slide through a rotating shaft, both ends of the bracket are provided with concave arc-shaped support rails, and circular bottom plates are movably inserted in the two concave arc-shaped support rails, and the bottom plates are located directly below the middle of the horizontal top plate and the bracket when they reach the end of the base;

[0013] Through the above technical solution, the graphite assembly is placed on the bottom plate, and the bottom plate moves with the bracket and the supporting slide to transport the graphite assembly. The graphite assembly can be placed on both bottom plates. When the bracket is rotated, the positions of the two bottom plates can be exchanged. After the graphite assembly on one bottom plate is destacking, the graphite assembly on the other bottom plate can be destacking, thereby reducing the working interval time.

[0014] The limiting pin clamps one of the lifters in one direction, and the power component drives the other lifter to move laterally, so that the two lifters can move away from each other, closer to each other, or move laterally together. When the two lifters move away from each other, the bracket and the horizontal top plate can be moved to both sides of the graphite component. When the two lifters move closer to each other, the horizontal top plate can push the graphite component toward the bracket and into the bracket. When the two lifters drive the bracket and the horizontal top plate up and down respectively, the upper graphite component can be rotated relative to the lower graphite component, so that a gap appears between the upper and lower graphite components for the horizontal top plate to be inserted between the upper and lower graphite components. The two lifters drive the bracket and the horizontal top plate to move up at the same time, so that the graphite components can be destackered. When the two lifters move laterally together, the graphite components can be transported.

[0015] Preferably, the power assembly includes a screw, a threaded sleeve, a portal frame and a motor. There are two portal frames, which are respectively fixed at the two ends of the main support frame. A screw is rotated between the two portal frames. The screw thread passes through the threaded sleeve. The lower end of the threaded sleeve is fixed to the upper end of the lifter. A motor is fixed to the side of one of the portal frames, and the output end of the motor is fixed to one end of the screw.

[0016] Through the above technical solution, the motor drives the screw to rotate after being energized, the screw drives the threaded sleeve to move laterally, and the threaded sleeve drives the lifter to move laterally, so that the power component can drive the lifter to move laterally.

[0017] Preferably, the lifter comprises a power source, a shell and a lifting column, the shell slides transversely in the main support frame, the power source is fixed in the shell, and the lifting column is fixed downward at the output end of the power source, the upper end of the shell in one lifter is fixed to the lower end of the threaded sleeve, the lifting column in the lifter fixed to the lower end of the threaded sleeve fixes the transverse top plate, and the lifting column in the other lifter rotates with a card frame through a rotating shaft;

[0018] Through the above technical solution, the power source drives the lifting column to move up and down after being energized, and the lifting columns in the two lifters respectively drive the horizontal top plate and the bracket to move up and down, so that the two lifters respectively drive the horizontal top plate and the bracket to move up and down.

[0019] Preferably, an auxiliary fixing assembly is installed between the two lifters;

[0020] The auxiliary fixing assembly includes an inner lifting cylinder, an assembly support frame, an x-axis sliding frame, an insertion rod and a y-axis sliding frame, both ends of the assembly support frame pass through the inner lifting cylinder, the upper end of the inner lifting cylinder moves up and down and is inserted in the outer shell, the lifting column moves up and down and passes through the inner lifting cylinder, two x-axis sliding frames and two y-axis sliding frames are movably inserted in the assembly support frame, the two x-axis sliding frames are parallel, the two y-axis sliding frames are parallel, the two x-axis sliding frames are perpendicular to the two y-axis sliding frames, and the intersection of the x-axis sliding frame and the y-axis sliding frame moves downward and passes through the insertion rod;

[0021] Through the above technical scheme, the two x-direction sliding frames and the two y-direction sliding frames can be moved arbitrarily on the horizontal plane, and the position of the insertion rod can be adjusted according to the position of the hole of the graphite component. When the two lifters drive the horizontal top plate and the bracket to move upward, that is, when driving the graphite component to move upward, the insertion rod is inserted into the hole of the graphite component to prevent the graphite component from moving on the horizontal plane, that is, to prevent the graphite component from falling from between the horizontal top plate and the bracket, that is, to assist in fixing the graphite component.

[0022] Preferably, the telescopic assembly comprises an inner retracting rod, an outer extension tube and a second spring, one end of the outer extension tube is fixed to the outside of the housing of one of the lifters, the other end of the outer extension tube is movably inserted with the inner retracting rod, the other end of the inner retracting rod is fixed to the outside of the housing of the other lifter, and the second spring is fixed between the outer extension tube and the inner retracting rod;

[0023] Through the above technical solution, the telescopic component can make the two lifters always tend to approach each other, and the horizontal top plate and the bracket always tend to approach each other to clamp the graphite component at all times, and the lifter on the right can drive the lifter on the left to move horizontally to the left and right at any time through the telescopic component.

[0024] Preferably, the limiter comprises an electromagnet, a device shell, a limit rod and a third spring, the device shell is fixed to the side of the main support frame, an electromagnet is fixed in the device shell, the end of the device shell moves through the limit rod, the limit rod moves through the arrangement hole, a third spring is fixed between the limit rod and the main support frame, and the electromagnet magnetically attracts the limit rod after being energized;

[0025] Through the above technical solution, the electromagnet is energized to magnetically attract the limit rod, and the third spring is stretched. At this time, the limit rod is retracted into the device shell. When the electromagnet is de-energized, the third spring pushes the limit rod out again, that is, the lifter is selectively limited.

[0026] Preferably, a material blocking assembly is installed at one end of the base located directly below the transverse top plate and the bracket;

[0027] The material blocking assembly includes an arc-shaped baffle, a positioning rod, a first spring and a support rod, the lower ends of the positioning rod and the support rod are fixed to one end of the base located directly below the transverse top plate and the bracket, the upper end of the positioning rod is fixed to the upper end of the support rod, the positioning rod is located between the support rod and the bottom plate, the first spring is fixed on the upper side of the base, the support rod is located in the first spring, the upper end of the first spring is fixed with an arc-shaped baffle, the support rod moves up and down through the arc-shaped baffle, and the two ends of the arc-shaped baffle are respectively located directly below the two lifters;

[0028] Through the above technical solution, the arc baffle surrounds the graphite assembly to prevent the stacked graphite assemblies from tipping over and assist in stabilizing the graphite assembly. The arc baffle and the positioning rod can position the graphite assembly so that workers can intuitively see whether the graphite assembly has moved to the specified position. When the lifting column in the lifter moves downward, the arc baffle will be pressed downward so that the arc baffle will not hinder the lateral movement of the upper graphite assembly. The arc baffle just blocks the lower graphite assembly to prevent the upper graphite assembly from moving laterally while driving the lower graphite assembly to move laterally through friction, thereby improving the stability of the graphite assembly.

[0029] The beneficial effects of the present invention are:

[0030] 1. Place the graphite assembly on the bottom plate, and the bottom plate moves with the bracket and the supporting slide to transport the graphite assembly. The graphite assembly can be placed on both bottom plates. After the graphite assembly on the front bottom plate is unstacking, the bracket can be rotated to exchange the positions of the two bottom plates. After the graphite assembly on one bottom plate is unstacking, the graphite assembly on the other bottom plate can be unstacking to reduce the working interval time;

[0031] 2. The limit pin clamps one of the lifters in one direction, and the power assembly drives the other lifter to move horizontally, so that the two lifters can move away from each other, closer to each other, or move horizontally together. When the two lifters move away from each other, the bracket and the horizontal top plate can be moved to both sides of the graphite assembly. When the two lifters move closer to each other, the horizontal top plate can push the graphite assembly toward the bracket and into the bracket. When the two lifters drive the bracket and the horizontal top plate up and down respectively, the upper graphite assembly can be rotated relative to the lower graphite assembly, so that a gap appears between the upper and lower graphite assemblies for the horizontal top plate to be inserted between the upper and lower graphite assemblies. The two lifters drive the bracket and the horizontal top plate to move up at the same time, so that the graphite assemblies can be destackered. When the two lifters move horizontally together, the graphite assemblies can be transported.

[0032] 3. In summary, the device can utilize two lifters to respectively drive the bracket and the horizontal top plate to move up and down, so as to actively separate the upper and lower graphite components. There is no need to manually carry the graphite components or insert the bracket and the horizontal top plate between the upper and lower graphite components. It is easy to use and reduces the labor intensity of workers. The graphite components can be transported by moving the bracket, the supporting slide and the bottom plate and changing their positions, and the graphite components can be transported by the horizontal movement of the lifter, so as to achieve the purpose of transporting the graphite components.

DETAILED DESCRIPTION

[0042] The following will refer to the attached Figures 1 to 8 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0043] As attached Figure 1 , Attachment Figure 3 and attached Figure 4 As shown, a destacking device for graphite heat exchanger production includes a base 3, a lifter 10, a main support frame 11, a transverse top plate 14 and a bracket 16;

[0044] Main support frame 11: The main support frame 11 is fixed on the roof support beam by iron bars, a power assembly 13 is installed on the upper side of the main support frame 11, and a linear array of arrangement holes 18 is provided on the side of the main support frame 11, a limit pin 8 is movably inserted into one of the arrangement holes 18, the limit pin 8 extends into the main support frame 11, and the limit pin 8 can be controlled to be inserted into different arrangement holes 18, a limiter 12 is installed on the main support frame 11, and the output end of the limiter 12 corresponds to one of the arrangement holes 18;

[0045] Lifter 10: There are two lifters 10 and both of them slide horizontally in the main support frame 11. One of the lifters 10 is fixed at the output end of the power assembly 13. The power assembly 13 drives the lifter 10 to slide horizontally. The other lifter 10 is located between the limit pin 8 and the limiter 12. A telescopic assembly 9 is fixed between the two lifters 10. The two lifters 10 move synchronously through the telescopic assembly 9.

[0046] Horizontal top plate 14: The horizontal top plate 14 is fixed to the output end of the lifter 10 installed on the output end of the power assembly 13, and the lifter 10 drives the horizontal top plate 14 to move up and down;

[0047] The bracket 16: An opening is arranged on the side of the bracket 16, and the upper and lower sides of the opening are inclined surfaces, forming a trumpet-shaped opening, which facilitates the insertion of the graphite component into the bracket 16. The bracket 16 rotates at the output end of the lifter 10 between the limit pin 8 and the limiter 12, and the lifter 10 drives the bracket 16 to move up and down. The bracket 16 and the horizontal top plate 14 are at the same height and correspond to each other on the left and right;

[0048] Base 3: The front end of the base 3 is semicircular, and the upper side is provided with a range limiting block 5 along the arc array. The base 3 is fixed below the general support frame 11. A supporting slide 2 is movably inserted in the base 3 along its length direction. A bracket 1 is rotated on the upper side of the supporting slide 2 through a rotating shaft. Concave arc support rails are provided at both ends of the bracket 1. A circular bottom plate 4 is movably inserted in the two concave arc support rails. A supporting groove is provided on the circular side surface of the bottom plate 4. The concave arc support rail supports the bottom plate 4 by inserting into the supporting groove. When the bottom plate 4 reaches the end of the base 3, it is located directly below the middle of the horizontal top plate 14 and the bracket 16, and the bottom plate 4 is located in the middle of the semicircle range limiting block 5 for positioning, and is attached Figure 3 It can be seen that an arc frame is provided at the end of the base 3, and the bottom plate 4 falls on the arc frame when reaching the end of the base 3.

[0049] As attached Figure 1 and attached Figure 3 As shown, the power assembly 13 includes a screw 131, a threaded sleeve 132, a door frame 133 and a motor 134. There are two door frames 133 and they are respectively fixed at both ends of the main support frame 11. A screw 131 rotates between the two door frames 133. The screw 131 passes through the threaded sleeve 132 through the threaded sleeve 132. The lower end of the threaded sleeve 132 is fixed to the upper end of the lifter 10. A motor 134 is fixed to the side of one of the door frames 133. The output end of the motor 134 is fixed to one end of the screw 131. The input end of the motor 134 is electrically connected to the mains to supply power to the motor 134.

[0050] The movement steps of the power assembly 13 are as follows: the motor 134 drives the screw rod 131 to rotate after being energized, the screw rod 131 drives the threaded sleeve 132 to move horizontally, and the threaded sleeve 132 drives the lifter 10 to move horizontally.

[0051] As attached Figure 1 and attached Figure 3As shown, the lifter 10 includes a power source 101, a shell 102 and a lifting column 103. The shell 102 slides horizontally in the main support frame 11. The power source 101 is fixed in the shell 102. The power source 101 is a cylinder or an electric push rod. The input end of the power source 101 is electrically connected to the mains to supply power to the power source 101. The output end of the power source 101 is fixed with a lifting column 103 facing downward. The upper end of the shell 102 in one lifter 10 is fixed to the lower end of the threaded sleeve 132. The lifting column 103 in the lifter 10 fixed to the lower end of the threaded sleeve 132 fixes the horizontal top plate 14. The lifting column 103 in the other lifter 10 is rotated by a rotating shaft with a bracket 16;

[0052] The movement steps of the lifter 10 are as follows: after the power source 101 is powered on, it drives the lifting column 103 to move up and down, and the lifting columns 103 in the two lifters 10 respectively drive the horizontal top plate 14 and the bracket 16 to move up and down.

[0053] As attached Figure 1 and attached Figure 5 As shown, an auxiliary fixing assembly 7 is installed between the two lifters 10;

[0054] The auxiliary fixing assembly 7 includes an inner lifting cylinder 71, an assembly support frame 72, an x-direction sliding frame 73, an insertion rod 74 and a y-direction sliding frame 75. Both ends of the assembly support frame 72 pass through the inner lifting cylinder 71. The upper end of the inner lifting cylinder 71 is movably inserted in the outer shell 102. The lifting column 103 moves up and down through the inner lifting cylinder 71. The side circular array of the lifting column 103 fixed with the horizontal top plate 14 has an external protrusion block 15. When the lifting column 103 moves upward, the external protrusion block 15 pushes the inner lifting cylinder 71 upward. Two x-direction sliding frames 73 and two y-direction sliding frames are movably inserted in the assembly support frame 72. The y-direction sliding frame 75 has screws passing through the internal threads of the component support frame 72. After the x-direction sliding frame 73 and the y-direction sliding frame 75 are positioned, the screws are pressed against the x-direction sliding frame 73 and the y-direction sliding frame 75 to fix the two. The two x-direction sliding frames 73 are parallel, the two y-direction sliding frames 75 are parallel, the two x-direction sliding frames 73 and the two y-direction sliding frames 75 are perpendicular to each other, and the intersection of the x-direction sliding frame 73 and the y-direction sliding frame 75 moves downward and passes through an insertion rod 74. The top diameter of the insertion rod 74 is larger than the internal width of the x-direction sliding frame 73 and the y-direction sliding frame 75 to ensure that the insertion rod 74 will not fall off;

[0055] The movement steps of the auxiliary fixing component 7 are as follows: arbitrarily move the two x-direction sliding frames 73 and the two y-direction sliding frames 75 on the horizontal plane to control the position of the insertion rod 74. When the insertion rod 74 is aligned with the hole of the graphite component, the two x-direction sliding frames 73 and the two y-direction sliding frames 75 can be fixed with screws to fix the insertion rod 74. When the two lifters 10 drive the horizontal top plate 14 and the bracket 16 to move downward, the inner lifting cylinder 71 will not fall out of the outer shell 102, which makes the component support frame 72, the x-direction sliding frame 73, the insertion rod 74 and the y-direction sliding frame 75 all prevented from falling downward, and the insertion rod 74 will not be inserted into the hole of the graphite component. When the two lifters 10 drive the horizontal top plate 14 and the bracket 16 to move upward, that is, drive the graphite component to move upward, the insertion rod 74 will be inserted into the hole of the graphite component to prevent the graphite component from moving on the horizontal plane, that is, to prevent the graphite component from falling.

[0056] As attached Figure 1 and attached Figure 3 As shown, the telescopic assembly 9 includes an inner retracting rod 91, an outer extension tube 92 and a second spring 93, one end of the outer extension tube 92 is fixed to the outside of the housing 102 of one of the lifters 10, the other end of the outer extension tube 92 is movably inserted with the inner retracting rod 91, the other end of the inner retracting rod 91 is fixed to the outside of the housing 102 of the other lifter 10, a second spring 93 is fixed between the outer extension tube 92 and the inner retracting rod 91, an inner slider 17 is fixed to the side of the outer extension tube 92, the inner slider 17 slides in the main support frame 11, so that the outer extension tube 92 and the inner retracting rod 91 slide in the main support frame 11, the lifter 10 slides in the main support frame 11 by being fixed in the outer extension tube 92 and the inner retracting rod 91, and the limiter 12 and the limit nail 8 limit the movement of the lifter 10 by blocking the inner slider 17;

[0057] The movement steps of the telescopic component 9 are: when the power component 13 drives one of the lifters 10 to move to the right, the two lifters 10 move away from each other, that is, the retracted rod 91 moves out of a part of the extended tube 92, and the second spring 93 is stretched. When the power component 13 drives the lifter 10 to move to the left, the second spring 93 pulls the retracted rod 91 and the extended tube 92 closer to each other, so that the two lifters 10 always tend to move closer to each other, that is, the horizontal top plate 14 and the bracket 16 always tend to move closer to each other, so as to clamp the graphite component at all times.

[0058] As attached Figure 1 , Attachment Figure 5 and attached Figure 7As shown, the limiter 12 includes an electromagnet 121, a device shell 122, a limit rod 123 and a third spring 124. The device shell 122 is fixed to the side of the main support frame 11, and the device shell 122 is aligned with one of the arrangement holes 18. The electromagnet 121 is fixed in the device shell 122, and the input end of the electromagnet 121 is electrically connected to the external mains. The end of the device shell 122 moves through the limit rod 123, and the limit rod 123 moves through the arrangement hole 18. The third spring 124 is fixed between the limit rod 123 and the main support frame 11. After the electromagnet 121 is energized, the limit rod 123 is magnetically attracted;

[0059] The movement steps of the limiter 12 are as follows: when the lifter 10 on the right pushes the lifter 10 on the left to move to the left through the telescopic assembly 9, the electromagnet 121 is energized to magnetically attract the limit rod 123, and the third spring 124 is stretched. At this time, the limit rod 123 is retracted into the housing 122, which will not hinder the lifter 10 on the left from moving to the left. However, when the lifter 10 on the right pulls the lifter 10 on the left to move to the right through the telescopic assembly 9, the electromagnet 121 is de-energized, so that the third spring 124 pushes out the limit rod 123, and the limit rod 123 blocks the lifter 10 on the left. At this time, the lifter 10 on the right is still moving to the right, so that the two lifters 10 are separated, and the horizontal top plate 14 and the bracket 16 are separated to put down the graphite assembly.

[0060] After the graphite assembly is lowered, the electromagnet 121 continues to be energized to magnetically attract the limit rod 123, and the third spring 124 is stretched. At this time, the limit rod 123 retracts into the device shell 122, so that the left lifter 10 is smoothly pulled to the right by the right lifter 10.

[0061] As attached Figure 1 As shown, a material blocking assembly 6 is installed at one end of the base 3 located directly below the transverse top plate 14 and the bracket 16;

[0062] The material blocking assembly 6 includes an arc-shaped baffle plate 61, a positioning rod 62, a first spring 63 and a support rod 64. The lower ends of the positioning rod 62 and the support rod 64 are fixed to one end of the base 3 located directly below the transverse top plate 14 and the bracket 16. The upper end of the positioning rod 62 is fixed to the upper end of the support rod 64. The positioning rod 62 is located between the support rod 64 and the bottom plate 4. The first spring 63 is fixed to the upper side of the base 3. The support rod 64 is located in the first spring 63. The upper end of the first spring 63 is fixed with an arc-shaped baffle plate 61. The support rod 64 moves up and down through the arc-shaped baffle plate 61. The two ends of the arc-shaped baffle plate 61 are respectively located directly below the two lifters 10.

[0063] The movement steps of the material baffle assembly 6 are as follows: the arc baffle 61 surrounds the graphite assembly to prevent the stacked graphite assembly from tipping over and assist in stabilizing the graphite assembly, and the arc baffle 61 and the positioning rod 62 can position the graphite assembly so that the worker can intuitively see whether the graphite assembly has moved to the specified position, and when the lifting column 103 in the lifter 10 moves downward, the arc baffle 61 will be pressed downward so that the arc baffle 61 will not hinder the lateral movement of the upper graphite assembly, and the arc baffle 61 just blocks the lower graphite assembly to prevent the upper graphite assembly from driving the lower graphite assembly to move laterally through friction when moving lateral, thereby improving the stability of the graphite assembly.

[0064] The movement steps of this device are:

[0065] The graphite components are placed on the bottom plate 4, and the graphite components are stacked up and down, as shown in the attached Figure 8 As shown in state a, the bracket 1 and the supporting slide 2 are pushed forward to move the front bottom plate 4 and the graphite assembly thereon to the bottom of the auxiliary fixing assembly 7, until the bottom plate 4 is stuck in the middle of the half-circle range limiting block 5, and the bottom plate 4 is against the positioning rod 62 to achieve positioning. At this time, the bottom plate 4 and the graphite assembly are manually pressed, and the bracket 1 and the supporting slide 2 are pushed backward at the same time to make the bottom plate 4 fall on the base 3 to complete the transportation. When the graphite assembly on the bottom plate 4 is used up, the graphite assembly is stacked on the bottom plate 4 at the back. At this time, the bracket 1 and the supporting slide 2 are pushed forward again to insert the front empty bottom plate 4 into the supporting slide 2, and push the bracket 1 and the supporting slide 2 forward for a distance, and then rotate the supporting slide 2 to make the bottom plate 4 of the stacked graphite assembly at the back rotate to the front, and the empty bottom plate 4 rotate to the back, so as to realize the conversion of the front and rear bottom plates 4, so as to continuously transport the stacked graphite assemblies and shorten the transportation time.

[0066] When the stacked graphite components on the bottom plate 4 are destacking, the power component 13 drives the right lifter 10 to move right, and the right lifter 10 drives the left lifter 10 to move right through the telescopic component 9, until the limit pin 8 blocks the inner slider 17, so that the left lifter 10 no longer moves, while the right lifter 10 continues to move for a distance, and then the right lifter 10 drives the horizontal top plate 14 to move downward, and the left lifter 10 drives the bracket 16 to move downward, until the horizontal top plate 14 and the topmost graphite component are at the same height. In addition, at this time, the lifter 10 will also press the arc baffle 61 downward to make the arc baffle 61 leave the upper graphite component and clamp the lower graphite component, and then the power component 13 drives the right lifter 10 to move left, and the horizontal top plate 14 drives the graphite component to move left, as shown in the attached figure. Figure 8As shown in state b in the figure, until the graphite assembly is inserted into the bracket 16, the left lifter 10 drives the bracket 16 to move downward for a distance again, and the graphite assembly continues to move to the left, so that the graphite assembly starts to rotate, as shown in the attached figure. Figure 8 As shown in state c in the figure, at this time, the horizontal top plate 14 still moves to the left, so that the horizontal top plate 14 moves to the bottom of the graphite assembly, and then the left lifter 10 drives the bracket 16 to move upward until the bracket 16 and the horizontal top plate 14 are at the same height. At this time, the two lifters 10 drive the bracket 16 and the horizontal top plate 14 to move upward at the same time, and the horizontal top plate 14 and the bracket 16 grab the graphite assembly and move upward together, as shown in the attached figure. Figure 8 As shown in state d in the figure, until the insertion rod 74 is inserted into the hole of the graphite component to fix the graphite component;

[0067] Then the power assembly 13 drives the lifter 10 to move to the left until the graphite assembly is transported to the designated position, and the limit rod 123 in the limiter 12 extends out to block the inner slider 17, that is, fix the lifter 10 on the left, and the power assembly 13 drives the lifter 10 on the right to move to the right, so that the transverse top plate 14 and the bracket 16 are separated to release the graphite assembly, and then the limit rod 123 in the limiter 12 retracts and no longer blocks the inner slider 17, and the power assembly 13 drives the lifter 10 to move rightward back to its original position;

[0068] In summary, the transportation and destacking process of graphite components is realized.
