Description

Technical Field

[0001] The present invention relates to the field of powder melting metal additive manufacturing, and specifically to an automatic cylinder handling device for a powder melting metal additive printing device. Background Art

[0002] Currently, in the field of powder melting metal additive manufacturing, for the products printed by a 3D printing device, it is necessary to remove the forming cylinder through the transfer mechanism of the 3D printing device itself, and then the worker transfers the forming cylinder to the offline through a crane device or a forklift device for the treatment of the next process. On the contrary, for the online of an empty cylinder, the worker transfers the empty cylinder to the transfer mechanism of the 3D printing device through a crane device or a forklift device, and the transfer mechanism moves the empty cylinder to the working position of the 3D printing device for printing work.

[0003] The related technology uses a slide table assembly to drive the lifting assembly to move horizontally left and right, so that the lifting assembly drives the fork assembly thereon to move to the position of the cylinder. The fork assembly drives the fork thereon to move to the upper part of the cylinder, and a set of support blocks at the front end of the fork and the support blocks on the cylinder are used to perform self-centering limit on the cylinder, so that the fork is connected to the cylinder, thereby driving the cylinder to move.

[0004] However, the above connection method makes the end of the fork rigidly connected to the cylinder. When the fork picks up and moves the cylinder back and forth or the slide table assembly drives the cylinder to move horizontally left and right, the fork will immediately drive the cylinder to move synchronously. Since the inside of the cylinder is in a full powder state, the weight of the cylinder is relatively heavy, so the inertia of the cylinder is relatively large. The printing material inside the cylinder will shake or even displace relative to the cylinder under the action of inertia, and there is a risk of material dumping. Summary of the Invention

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an automatic cylinder handling device for a powder melting metal additive printing device, including a slide table assembly, on which a lifting assembly is slidably arranged along its track.

[0009] Preferably, the connection component includes three first connection blocks fixedly installed at equal intervals in the front-rear direction on one side of the buffer plate close to the cylinder block. The connection component also includes three second connection blocks fixedly installed at equal intervals in the front-rear direction on the side of the placement plate away from the cylinder block. Both the first connection block and the second connection block are in a right trapezoidal structure, and the inclined surfaces of the first connection block and the corresponding second connection block face each other.

[0010] Preferably, a V-shaped groove is formed on the inclined surface of the middle first connection block, and a triangular convex block is fixedly installed on the inclined surface of the middle second connection block. The shape of the triangular convex block corresponds to that of the V-shaped groove.

[0011] Preferably, an isosceles trapezoidal connection sliding groove is formed on the inclined surface of the first connection blocks on the front and rear sides, and an isosceles trapezoidal connection sliding block is fixedly installed on the inclined surface of the second connection blocks on the front and rear sides. The connection sliding block is located at the lower part of the inclined surface of the second connection block.

[0012] Preferably, the force relief component includes two first spring dampers arranged symmetrically in the front-rear direction and fixedly installed inside the moving plate. A follower block slidably connected inside the moving plate is fixedly installed in the middle of the side of the buffer plate away from the cylinder block.

[0013] Preferably, the force relief component further includes a driving plate and a toothed plate slidably connected up and down inside the moving plate. The toothed plate is connected to the upper part of the driving plate through a spiral spring. The toothed plate is located below the follower block. Two groups of teeth are symmetrically arranged on the toothed plate in the front-rear direction. Each group is composed of teeth fixedly installed on the toothed plate at equal intervals in the front-rear direction.

[0014] Preferably, the force relief component further includes an electric push rod fixedly installed inside the moving plate. The telescopic section of the electric push rod is fixedly connected to the driving plate. A clamping plate is fixedly installed in the middle of the lower side of the follower block.

[0015] Preferably, the synchronization component includes two sliding plates arranged symmetrically left and right and slidably arranged on the support plate. The front part of the sliding plate is fixedly connected to the corresponding moving plate. A synchronization plate is rotatably connected to the middle of the rear side of the sliding plate member. Both ends of the synchronization plate are hinged to the sliding plate through hinge plates. A first hydraulic rod is fixedly connected between the two sliding plates.

[0016] Preferably, the speed control component includes a second hydraulic rod fixedly installed on the upper part of the support plate.

[0017] Preferably, the upper part of the sliding plate member has a V-shaped structure, and the lower part of the speed control member has a pointed structure corresponding to the V-shaped structure of the sliding plate member. A connecting groove is fixedly arranged on the pointed structure of the speed control member, and insertion blocks for inserting into the inside of the connecting groove are symmetrically and fixedly arranged on the left and right of the V-shaped structure of the sliding plate member.

[0018] The beneficial effects of the present invention are as follows: First, the present invention uses a synchronization component to drive the connection component to be connected to the cylinder block through the moving plate, so that the sliding plate member and the cylinder block are locked into a whole. When the forklift assembly drives the cylinder block to move back and forth through the forklift, the force-relieving component buffers the inertia when the cylinder block starts through the buffer plate, so that the cylinder block starts slowly, thereby preventing the materials inside the cylinder block from tipping over.

[0019] Second, the present invention uses a speed control component to control the speed of the cylinder block moving with the sliding table assembly. When the sliding table assembly drives the cylinder block to move horizontally left and right, the speed control component can make the cylinder block start slowly when the sliding table assembly starts, and can push the cylinder block to the middle position of the forklift when the sliding table assembly moves at a constant speed and stops. While preventing the materials inside the cylinder block from tipping over, it ensures the accuracy of the cylinder block placed on the working station.

[0020] Third, when the present invention uses the connection component to connect the cylinder block and the forklift, it can also lift the cylinder block upward, so that the outer side of the upper part of the cylinder block moves to the inside of the annular airbag. Then, the air pump is used to inflate the inside of the annular airbag, so that the annular airbag fills between the surrounding baffle, the sealing cover and the outer side of the cylinder block, thereby sealing the cylinder block. On the one hand, it can prevent air from contacting the materials inside the cylinder block, resulting in oxidation of the printed materials. On the other hand, the flow and compression of the air inside the annular airbag can further buffer the movement of the cylinder block, further preventing the materials inside the cylinder block from tipping over.

[0034] Embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, the technologies or conditions described in the literature in the art or according to the product instructions are followed.

[0035] Refer to Figure 1 , Figure 2 and Figure 3 , an automatic cylinder handling device for a powder melting metal additive manufacturing equipment, including a sliding table assembly 1, on which a lifting assembly 2 is slidably arranged along its track. Inside the lifting assembly 2, a fork assembly 3 is arranged. The fork assembly 3 includes a fork 31 connected to the lifting assembly 2 through a power guiding mechanism 33. Inside the front end of the fork 31, a sealing cover 32 controlled by a cylinder slides up and down. The fork assembly 3 further includes a buffering mechanism 34 for buffering the movement of the cylinder, and the fork assembly 3 further includes a sealing mechanism 35 for assisting the sealing cover 32.

[0036] First, this device is arranged on the production line of the printing equipment so that it can cover all the printing equipment and auxiliary equipment on the production line. Subsequently, the workshop main control system issues production tasks and instructions according to the order. The AGV cart transports the empty cylinder to the loading and unloading platform. After this device receives the instruction, it takes the empty cylinder from the loading and unloading platform and places it at the loading and unloading opening of the 3D metal printing equipment. The 3D metal printing equipment automatically performs the printing work according to the instruction requirements. After the printing is completed, the formed cylinder is moved out to the loading and unloading opening. Then, after this device receives the instruction, it moves to the 3D metal printing equipment station, takes out the formed cylinder that has been printed, and then this device drives the formed cylinder to move to the next station.

[0037] When this device handles the formed cylinder, first, the sliding table assembly 1 drives the fork assembly 3 to horizontally move left and right through the lifting assembly 2 to align with the position of the formed cylinder. Subsequently, the power guiding mechanism 33 drives the fork 31 to move forward to cover the upper part of the formed cylinder. Then, through the buffering mechanism 34, the fork 31 is connected to the formed cylinder, and at the same time, the formed cylinder is pushed upward to contact the sealing mechanism 35, so that the sealing mechanism 35 seals the upper opening of the formed cylinder. Then, the lifting assembly 2 drives the formed cylinder to move upward by moving the fork assembly 3 upward.

[0038] Then, the power guiding mechanism 33 drives the formed cylinder body to move backward through the forklift 31 until it leaves the loading and unloading port of the 3D metal printing device. During this process, the buffer mechanism 34 buffers the movement of the formed cylinder body to prevent the materials inside the formed cylinder body from tipping over. After that, the sliding table assembly 1 moves horizontally to drive the formed cylinder body to move to the next station. During this process, the buffer mechanism 34 can also buffer the movement of the formed cylinder body to further prevent the materials inside the formed cylinder body from tipping over. Finally, the forklift 31 extends and places the formed cylinder body at the loading and unloading port of the next station. Finally, after repeating the handling of the formed cylinder body and staying at all stations, the device transports the formed cylinder body to the unloading table on the production line of the printing device, thus completing the handling of one formed cylinder body.

[0039] Refer to Figure 2 、 Figure 3 and Figure 4 , the buffer mechanism 34 includes two symmetrically arranged moving plates 341 that are slidably arranged left and right inside the forklift 31 through guide columns. The buffer mechanism 34 further includes placing plates 342 that are respectively fixedly installed on the left and right sides of the cylinder body through bolts. A buffer plate 343 is slidably arranged in the front and rear directions on one side of the moving plate 341 close to the cylinder body. A connecting component 344 is arranged between the buffer plate 343 and the placing plate 342 at the corresponding position.

[0040] Refer to Figure 3 and Figure 4 , the connecting component 344 includes three first connecting blocks 3441 that are fixedly installed at equal intervals in the front and rear directions on one side of the buffer plate 343 close to the cylinder body. The connecting component 344 further includes three second connecting blocks 3442 that are fixedly installed at equal intervals in the front and rear directions on one side of the placing plate 342 away from the cylinder body. Both the first connecting block 3441 and the second connecting block 3442 are in the shape of a right trapezoid, and the inclined surfaces of the first connecting block 3441 and the second connecting block 3442 at the corresponding position face each other.

[0041] Continue to refer to Figure 3 and Figure 4 , a V-shaped groove 3443 is formed on the inclined surface of the first connecting block 3441 located in the middle. A triangular convex block 3444 is fixedly installed on the inclined surface of the second connecting block 3442 located in the middle. The shape of the triangular convex block 3444 corresponds to that of the V-shaped groove 3443.

[0042] Refer to Figure 3 、 Figure 4 and Figure 5 , isosceles trapezoidal connecting chutes 3445 are formed on the inclined surfaces of the first connecting blocks 3441 located on the front and rear sides. Isosceles trapezoidal connecting sliders 3446 are fixedly installed on the inclined surfaces of the second connecting blocks 3442 located on the front and rear sides. The connecting sliders 3446 are located at the lower part of the inclined surface of the second connecting block 3442.

[0043] The operator pre-fixes the placement plate 342 on the left and right side surfaces of the cylinder block. When the forklift 31 moves forward to cover the upper part of the formed cylinder block, the forklift 31 drives the two buffer plates 343 to move to the left and right side positions of the formed cylinder block respectively through the moving plate 341, and makes the positions of the buffer plates 343 correspond to those of the placement plate 342, so that the buffer plates 343 drive the first connecting blocks 3441 thereon to correspond to the positions of the second connecting blocks 3442 at the corresponding positions respectively.

[0044] Refer to Figure 3 、 Figure 9 and Figure 10 As shown in

[0045] Refer to Figure 2 、 Figure 9 、 Figure 10 and Figure 11 A speed control component 349 for controlling the moving speed of the sliding plate member 347 is further included in the buffer mechanism 34. The speed control component 349 includes a second hydraulic rod 3491 fixedly installed on the upper part of the support plate 346. A push plate 3492 and a speed control member 3493 are slid up and down inside the support plate 346. The lower part of the push plate 3492 is connected to the speed control member 3493 through a second spring damping rod 3497. The telescopic section of the second hydraulic rod 3491 is fixedly connected to the push plate 3492. A push rod 3494 is fixedly installed on the lower part of the push plate 3492.

[0046] Refer to Figure 10 and Figure 11 The upper part of the sliding plate member 347 is of a V-shaped structure. The lower part of the speed control member 3493 is of a pointed structure corresponding to the V-shaped structure of the sliding plate member 347. A connecting groove 3495 is fixedly arranged on the pointed structure of the speed control member 3493. Insertion blocks 3496 for inserting into the inside of the connecting groove 3495 are fixedly arranged symmetrically left and right on the V-shaped structure of the sliding plate member 347.

[0047] In the initial state, the telescopic section of the second hydraulic rod 3491 is in the extended state, causing the telescopic section of the second hydraulic rod 3491 to push down the push plate 3492, resulting in the push plate 3492 abutting against the upper side of the speed control part 3493 through the push rod 3494. Thus, the pointed structure at the lower part of the speed control part 3493 is inserted into the V-shaped structure of the sliding plate member 347 through the push of the push rod 3494, and then the speed control part 3493 pushes the sliding plate member 347 to be locked at the middle position of the support plate 346. At the same time, the rotation center of the synchronous plate 3482 driven by the sliding plate member 347 is also located at the middle position of the support plate 346. And at this time, the second spring damper rod 3497 is in the compressed state, and the insertion block 3496 is not inserted into the connecting groove 3495.

[0048] Subsequently, the telescopic section of the first hydraulic rod 3484 is retracted, causing the first hydraulic rod 3484 to drive the two moving plates 341 to approach each other through the sliding plate 3481. At the same time, the sliding plate 3481 pushes the synchronous plate 3482 to rotate through the hinge plate 3483, enabling the synchronous plate 3482 to drive the two moving plates 341 to move synchronously and in opposite directions relative to its rotation center. Thus, the two moving plates 341 drive the inclined surfaces of the first connecting block 3441 to move synchronously to fit against the inclined surfaces of the corresponding second connecting blocks 3442 through the buffer plate 343.

[0049] During the process of the inclined surface of the first connecting block 3441 coming into contact and fitting with the inclined surface of the corresponding second connecting block 3442, the middle first connecting block 3441 drives the V-shaped groove 3443 thereon to move to the outside of the triangular convex block 3444 of the middle second connecting block 3442. The triangular convex block 3444 is inserted into the inside of the V-shaped groove 3443, enabling the two inclined surfaces of the triangular convex block 3444 to be aligned and fitted with the two inclined surfaces of the V-shaped groove 3443, and adjusting the positions of the first connecting block 3441 and the corresponding second connecting block 3442 to be exactly corresponding.

[0050] Then, continue to retract the telescopic section of the first hydraulic rod 3484, causing the first connecting blocks 3441 on the left and right sides to continue to move synchronously towards the middle of the forklift fork 31. The inclined surface of the first connecting block 3441 slides relative to the inclined surface of the second connecting block 3442, so that the first connecting block 3441 pushes the second connecting block 3442 upwards, and the second connecting block 3442 drives the forming cylinder body to move upwards synchronously through the placing plate 342.

[0051] During this process, the connecting sliding grooves 3445 on the first connecting blocks 3441 on the front and rear sides slide to the outside of the connecting sliders 3446 of the second connecting blocks 3442 at corresponding positions. Through the connection between the connecting sliding grooves 3445 and the connecting sliders 3446, the first connecting blocks 3441 and the second connecting blocks 3442 are slidably connected together. When the first connecting block 3441 abuts against the placement plate 342, the first connecting block 3441 and the forming cylinder body are locked into a whole, so that the buffer plate 343 and the forming cylinder body are also locked into a whole, and further enables the sliding plate member 347 to move synchronously left and right with the forming cylinder body.

[0052] Refer to Figure 2 , Figure 3 and Figure 8 , the sealing mechanism 35 includes a baffle plate 351 fixedly installed on the forklift 31 through a plug post inserted into the lower side of the sealing cover 32. An annular airbag 352 is fixedly installed inside the baffle plate 351, and an air pump 353 communicated with the annular airbag 352 is fixedly installed on the upper part of the forklift 31.

[0053] In the initial state, the annular airbag 352 is in an unexpanded state, and at the same time, the upper side of the annular airbag 352 abuts against the lower side surface of the sealing cover 32. When the first connecting block 3441 abuts against the placement plate 342, the upper end of the forming cylinder body moves upward to the outside of the annular airbag 352. Subsequently, the air pump 353 is used to inflate the annular airbag 352, causing the annular airbag 352 to start expanding, so that the annular airbag 352 fills the space between the baffle plate 351, the sealing cover 32 and the outside of the cylinder body, thereby sealing the upper opening of the forming cylinder body and preventing the materials inside the forming cylinder body from being oxidized.

[0054] Refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 , a force relief component 345 is arranged between the buffer plate 343 and the moving plate 341 at the corresponding position. The force relief component 345 includes two first spring damping rods 3451 arranged symmetrically before and after and fixedly installed inside the moving plate 341. A follower block 3452 slidably connected inside the moving plate 341 is fixedly installed in the middle of the side of the buffer plate 343 away from the cylinder body.

[0055] Refer to Figure 6 and Figure 7 , the force relief component 345 further includes a driving plate 3453 and a tooth plate 3454 that are slidably connected up and down inside the moving plate 341. The tooth plate 3454 is connected to the upper part of the driving plate 3453 through a spiral spring. The tooth plate 3454 is located below the follower block 3452. Two groups of teeth are symmetrically arranged on the tooth plate 3454 before and after, and each group is composed of teeth fixedly installed on the tooth plate 3454 at equal intervals before and after.

[0056] Continue to refer to Figure 6 and Figure 7 The force release assembly 345 further includes an electric push rod 3455 fixedly installed inside the moving plate 341. The telescopic section of the electric push rod 3455 is fixedly connected to the active plate 3453. A clamping plate 3456 is fixedly installed in the middle of the lower side of the follower block 3452.

[0057] After the annular airbag 352 seals the upper opening of the forming cylinder body, the lifting assembly 2 drives the forming cylinder body to move upward through the forklift 31. Subsequently, the power guiding mechanism 33 drives the forklift 31 to move backward. At this time, synchronously contract the telescopic section of the electric push rod 3455, so that the electric push rod 3455 drives the active plate 3453 to move upward. The active plate 3453 pushes the toothed plate 3454 through the spiral spring to abut against the lower side surface of the clamping plate 3456.

[0058] When the forklift 31 moves backward, the forming cylinder body remains stationary under the action of inertia, so that the forming cylinder body drives the buffer plate 343 to remain stationary synchronously. Further, when the forklift 31 starts to move backward, the forklift 31 drives the moving plate 341 to move backward relative to the buffer plate 343. The moving plate 341 drives the front first spring damper rod 3451 to abut against the follower block 3452 and compress it. As the front first spring damper rod 3451 is gradually compressed, the elastic force of the first spring damper rod 3451 increases, and the required thrust for its compression gradually increases, so that the inertia of the forming cylinder body can no longer compress the front first spring damper rod 3451 through the follower block 3452. Further, the front first spring damper rod 3451 slowly drives the forming cylinder body to move backward.

[0059] When the moving plate 341 moves backward relative to the buffer plate 343, the moving plate 341 drives the toothed plate 3454 to move backward relative to the clamping plate 3456, so that the clamping plate 3456 contacts the inclined surfaces of a set of teeth on the front side of the toothed plate 3454 one by one, and intermittently drives the toothed plate 3454 to move downward by pushing the teeth downward. When the front first spring damper rod 3451 pushes the forming cylinder body to move backward to the same speed as the forklift 31, the clamping plate 3456 and the toothed plate 3454 are relatively stationary, so that the spiral spring pushes the vertical section of the teeth of the toothed plate 3454 to block the clamping plate 3456 through its own elastic force, preventing the front first spring damper rod 3451 from pushing the follower block 3452 to move backward relative to the buffer plate 343, thereby avoiding the excessive speed of the forming cylinder body and ensuring the stability of the forming cylinder body.

[0060] While the forklift forks 31 start to move backward, the forklift forks 31 drive the annular airbag 352 to move synchronously, causing the formed cylinder block to press the annular airbag 352 forward by its own inertia, so that the gas inside the front side of the annular airbag 352 moves to its rear side, thereby ensuring the filling of the gap between the surrounding baffle 351, the sealing cover 32 and the outer side of the formed cylinder block by the annular airbag 352, thus ensuring the sealing effect. Moreover, through the compression of the air inside the annular airbag 352, the start of the formed cylinder block can also be buffered, further increasing the buffering effect.

[0061] When the forklift forks 31 drive the formed cylinder block to move backward to the specified position, the power guiding mechanism 33 stops driving the forklift forks 31, causing the forklift forks 31 to drive the formed cylinder block to stop slowly. Subsequently, the telescopic section of the electric push rod 3455 extends to drive the tooth plate 3454 to no longer block the clamping plate 3456, enabling the front first spring damping rod 3451 to slowly push the follower block 3452 through its own elastic force, moving the follower block 3452 to the initial position in the middle of the moving plate 341.

[0062] It should be noted that in the initial state, the front and rear first spring damping rods 3451 are in a pre-compressed state. When the front first spring damping rod 3451 pushes the follower block 3452 backward to reset, it has sufficient elastic force to push the follower block 3452 to the initial position in the middle of the moving plate 341. And through the blocking of the rear first spring damping rod 3451, when the moving plate 341 is stationary, the follower block 3452 can be maintained at the initial position in the middle of the moving plate 341 by the forward and backward pushing of the front and rear first spring damping rods 3451.

[0063] Then the sliding table assembly 1 drives the formed cylinder block to move rightward to the next working station through the forklift forks 31. While the sliding table assembly 1 starts, the telescopic section of the second hydraulic rod 3491 is retracted, causing the push rod 3494 to no longer push the speed control part 3493. However, the elastic force of the second spring damping rod 3497 still makes the speed control part 3493 fit on the V-shaped structure of the sliding plate part 347. When the forklift forks 31 move rightward, the formed cylinder block remains stationary under the action of inertia, causing the formed cylinder block to drive the sliding plate part 347 to move leftward relative to the speed control part 3493. As a result, the right inclined surface of the V-shaped structure of the sliding plate part 347 pushes the speed control part 3493 upward, and the speed control part 3493 gradually compresses the second spring damping rod 3497.

[0064] Meanwhile, the connecting groove 3495 on the right side of the speed control member 3493 is slidably connected to the insertion block 3496 on the right side of the sliding plate member 347, so that the speed control member 3493 is slidably connected to the sliding plate member 347. As the sliding plate member 347 gradually compresses the second spring damping rod 3497, the elastic force of the second spring damping rod 3497 gradually increases, making it increasingly difficult for the sliding plate member 347 to push the speed control member 3493 upward. Furthermore, the speed control member 3493 starts to drive the forming cylinder to slowly move to the right through the sliding plate member 347.

[0065] At the same time, the annular airbag 352 further buffers the movement of the forming cylinder by the same principle above. When the forming cylinder and the forklift 31 move at the same speed, the elastic force of the second spring damping rod 3497 slowly pushes the speed control member 3493 downward, causing the speed control member 3493 to drive the sliding plate member 347 to slowly move to the middle position of the support plate 346. Then, the telescopic section of the second hydraulic rod 3491 extends again to press the speed control member 3493 against the sliding plate member 347, enabling the forming cylinder and the forklift 31 to move at a stable and equal speed. When the forklift 31 drives the forming cylinder to move to the specified position to the right, the sliding table assembly 1 stops driving the forklift 31, causing the forklift 31 to drive the forming cylinder to slowly stop.

[0066] Subsequently, the power guiding mechanism 33 extends the forklift 31 to drive the forming cylinder to move back and forth to the working station. The annular airbag 352 and the buffer plate 343 buffer the forming cylinder by the same principle above. Then, the first hydraulic rod 3484 extends to drive the moving plates 341 on both sides to move away from each other, thereby placing the forming cylinder on the working station.

[0067] Refer to Figures 1 - 11 When the present invention transports the forming cylinder to the next working station, the following steps are further included: First step, the sliding table assembly 1 drives the forklift assembly 3 to horizontally move left and right through the lifting assembly 2 to align with the position of the forming cylinder. Subsequently, the power guiding mechanism 33 drives the forklift 31 to move forward to cover the upper part of the forming cylinder.

[0068] Second step, the telescopic section of the first hydraulic rod 3484 is retracted to drive the first connecting block 3441 to be connected to the second connecting block 3442, and the forming cylinder is synchronously driven to move upward by pushing the second connecting block 3442 upward, so that the upper end of the forming cylinder moves upward to the outside of the annular airbag 352.

[0069] Third step, air is pumped into the annular airbag 352 through the air pump 353, so that the annular airbag 352 is filled between the surrounding baffle 351, the sealing cover 32 and the outside of the cylinder, thereby sealing the upper opening of the forming cylinder to prevent the materials inside the forming cylinder from being oxidized.

[0070] In the fourth step, the lifting assembly 2 drives the formed cylinder body to move upward through the forklift 31. Subsequently, the power guiding mechanism 33 drives the forklift 31 to move backward. At this time, the telescopic section of the electric push rod 3455 is synchronously contracted, so that the electric push rod 3455 drives the active plate 3453 to move upward. The active plate 3453 pushes the tooth plate 3454 against the lower side of the clamping plate 3456 through the spiral spring.

[0071] In the fifth step, when the forklift 31 moves backward, the formed cylinder body remains stationary under the action of inertia. The first spring damper rod 3451 on the front side pushes the formed cylinder body to move slowly backward through its gradually increasing elastic force, preventing the materials inside the formed cylinder body from tipping over. When the moving speed of the formed cylinder body is the same as that of the forklift 31, the clamping plate 3456 cooperates with the tooth plate 3454 to prevent the first spring damper rod 3451 on the front side from pushing the follower block 3452 to move backward relative to the buffer plate 343, ensuring the stability of the formed cylinder body.

[0072] In the sixth step, the forklift 31 drives the annular airbag 352 to move synchronously, so that the formed cylinder body presses the annular airbag 352 forward through its own inertia, causing the gas inside the front side of the annular airbag 352 to move to its rear side, thereby ensuring the filling of the gap between the baffle 351, the sealing cover 32 and the outer side of the formed cylinder body by the annular airbag 352, thus ensuring the sealing effect. And through the compression of the air inside the annular airbag 352, the start of the formed cylinder body can also be buffered, further increasing the buffering effect.

[0073] In the seventh step, when the forklift 31 drives the formed cylinder body to move backward to the specified position, the power guiding mechanism 33 stops driving the forklift 31, so that the forklift 31 drives the formed cylinder body to stop slowly. Subsequently, the telescopic section of the electric push rod 3455 is extended to drive the tooth plate 3454 to no longer block the clamping plate 3456, so that the first spring damper rod 3451 on the front side slowly pushes the follower block 3452 to move to the initial position in the middle of the moving plate 341 through its own elastic force.

[0074] In the eighth step, the sliding table assembly 1 drives the formed cylinder body to move to the next working station to the right through the forklift 31. At the same time, the telescopic section of the second hydraulic rod 3491 is contracted. The formed cylinder body drives the sliding plate member 347 to drive the speed control member 3493 to gradually compress the second spring damper rod 3497, and the elastic force of the second spring damper rod 3497 gradually drives the formed cylinder body to move slowly to the right.

[0075] In the ninth step, when the formed cylinder block and the forklift fork 31 move at a constant speed, the elastic force of the second spring damping rod 3497 slowly drives the sliding plate member 347 to move to the middle position of the support plate 346. Then, the telescopic section of the second hydraulic rod 3491 is extended again to press the speed control member 3493 against the sliding plate member 347, so that the formed cylinder block and the forklift fork 31 move at a stable constant speed. When the forklift fork 31 drives the formed cylinder block to move backward to the designated position, the slide table assembly 1 stops driving the forklift fork 31, so that the forklift fork 31 drives the formed cylinder block to slowly stop.

[0076] In the tenth step, the power guiding mechanism 33 extends the forklift fork 31 to drive the formed cylinder block to move back and forth to the working station. The annular airbag 352 and the buffer plate 343 buffer the formed cylinder block by the same principle as above. Then, the first hydraulic rod 3484 is extended to drive the moving plates 341 on both sides to move away from each other, so as to place the formed cylinder block on the working station.

[0077] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
