Description

Technical Field

[0001] This utility model relates to the technical field of 3D printing, and in particular to a transport device for moving cylinders and a 3D printer. Background Technology

[0002] 3D printing, also known as additive manufacturing, is an emerging manufacturing technology that uses digital models as a basis to build up materials layer by layer to create physical objects. Additive manufacturing equipment can directly build solid parts "from scratch", without following the traditional process of blanking, roughing, and finishing, and without relying on special forming molds. It has advantages such as design freedom, manufacturing flexibility, low cost, and short cycle time.

[0003] Laser bed fusion (LPBF) is one of the most common techniques in metal additive manufacturing. It uses a laser energy source to selectively fuse particulate materials such as metals, ceramics, or polymers together according to a model to form a three-dimensional object. The LPBF process takes place in a forming cylinder, which is typically a rectangular cylinder with an open bottom wall. A laser printing device is mounted on the top wall of the forming cylinder, and a printing substrate is placed at the bottom opening. The printing material, such as metal, is fused and formed on the printing substrate.

[0004] The forming cylinder is usually fixed in place. After printing is completed inside the forming cylinder, the printing substrate placed in the forming cylinder needs to be removed to retrieve the printed solid part and to feed in the raw material. However, the installation and removal process of the printing substrate is cumbersome and not convenient for quick replacement. To improve printing efficiency, an attempt was made to fix the printing substrate and install and move the forming cylinder relative to the printing substrate. However, due to the large size of the forming cylinder, the problem of low efficiency still exists. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a transport device and 3D printer for moving cylinders that can quickly place and move molding cylinders to improve printing efficiency.

[0006] To solve the above-mentioned technical problems, firstly, the transport device for moving cylinders provided by this utility model adopts the following technical solution:

[0007] A transport device for moving a cylinder includes two horizontally arranged and parallel transport tracks. Each of the two transport tracks is equipped with a pushing mechanism that can push an object to be transported along the transport tracks. Each of the two pushing mechanisms has a lever at its free end. Pushing seats are spaced apart along the transport path from front to back of each lever. The pushing seats are fixed to the outer wall of the object to be transported and rest on the top surface of the transport tracks. A lifting mechanism is located below the two transport tracks. The portion of the transport tracks directly above the lifting mechanism is a horizontal position for printing and processing. When the object to be transported moves to the horizontal position for printing and processing, the lifting mechanism can raise and lower the object.

[0008] By adopting the above technical solution, a forklift is used to place the push seats on both sides of the forming cylinder onto the upper sides of two transport tracks, ensuring that the actuating components are positioned between the two push seats on the same side. The free end of the pushing mechanism then drives the actuating components to move along the transport path of the transport tracks, pushing the two push seats on the same side to achieve a push or pull action on the forming cylinder, thus moving the forming cylinder to the horizontal position for printing, i.e., the position of the lifting mechanism. After the forming cylinder reaches the printing position, the lifting end of the lifting mechanism rises, lifting the forming cylinder until its upper edge contacts the top laser printing equipment mounting plate, i.e., the forming plate reaches the vertical position for printing. At this point, the printing substrate is moved into the forming cylinder by a lifting device, and laser printing can then be performed.

[0009] After printing is complete, the lifting device lowers and removes the printing substrate. The lifting mechanism lowers the forming cylinder so that the pusher seat can be placed back on the transport track. At this point, the pushing mechanism drives the actuating component to push or pull the pusher seat, causing the forming cylinder to move horizontally away from the horizontal position of the printing process. Then, a forklift removes the forming cylinder from the transport track. This process allows for the rapid placement and movement of the forming cylinder relative to the printing substrate, facilitating the retrieval of printed products and the loading of raw materials. Connecting this transport device to the production line makes management more convenient and improves printing efficiency.

[0010] Optionally, each of the two transport tracks has a number of rolling elements on its upper side, and the push seat rests on the number of rolling elements.

[0011] By adopting the above technical solution, several rolling elements can transform the sliding friction of the push seat on the transport track into rolling friction, reducing the frictional force that causes the push seat to move relative to the transport track, thereby improving the efficiency and stability of the forming cylinder moving on the transport track.

[0012] Optionally, the rolling element is a ball, needle roller, roller, or slider.

[0013] Optionally, a first position sensor and a second position sensor are provided on the transport track. Both the first position sensor and the second position sensor are electrically connected to the control end of the pushing mechanism. The first position sensor is located at the printing and processing position, and the second position sensor is located at the position where the object to be transported is to be moved.

[0014] By adopting the above technical solution, after the forklift moves the forming cylinder onto the transport rail, the pushing mechanism drives the forming cylinder to the horizontal position for printing. At this time, the first position sensor is detected and controls the pushing mechanism to close, so that the forming cylinder stops at this position. When the pushing mechanism drives the forming cylinder to the position to be moved, the second position sensor is detected and controls the pushing mechanism to close, so that the forming cylinder stops stably at this position.

[0015] Optionally, a first limiting block and a second limiting block are provided on the sidewalls of the two opposing transport tracks. The first limiting block is located near the first position sensor and on the side of the first position sensor away from the second sensor, and the second limiting block is located near the second position sensor and on the side of the second position sensor away from the first sensor.

[0016] By adopting the above technical solution, when the first position sensor controls the push mechanism to close, causing the forming cylinder to stop, the forming cylinder will still move forward due to inertia. The first limit block will block and intercept the forming cylinder, thereby making the forming cylinder accurately and stably stop at the horizontal position of the printing process.

[0017] Optionally, a correction cylinder is fixedly installed on the opposite edge of each of the two transport tracks, and the moving path of the driving end of the correction cylinder on both sides is perpendicular to the transport path. A correction rod is fixed to the driving end of the correction cylinder, and the length of the correction rod is parallel to the transport path and its length is greater than the distance between the two push seats on the same side. A bearing roller is provided on the side of the push seat away from the object to be transported.

[0018] By adopting the above technical solution, when the forklift places the forming cylinder on the transport rail, the forming cylinder may be offset relative to the transport direction. The correction cylinders on the two transport rails drive the correction rods to move toward the forming cylinder. The two correction rods abut and clamp the push seat of the forming cylinder. Then, by adjusting the rolling of the bearing rollers, the offset forming cylinder can be adjusted to be parallel to the transport direction, thus correcting the deviation. This allows the push mechanism to better drive the actuating part to push or pull the forming cylinder.

[0019] Optionally, the actuating component includes an actuating plate disposed at the driving end of the pushing mechanism and an actuating rod disposed on the actuating plate. The actuating plate and the actuating rod are both located between two pushing seats on the same side of the object to be transported, and the actuating rod is parallel to the transport path.

[0020] By adopting the above technical solution, the toggle plate allows the toggle lever to be placed between the two push seats. With the toggle lever having an axis parallel to the transport direction, the distance between the toggle plate and the two push seats can be reduced, thereby reducing the stroke of the push mechanism and improving efficiency.

[0021] Optionally, the actuating rod passes through the actuating plate, and the actuating rod slides relative to the actuating plate along its axis. Limiting portions are provided at both ends of the actuating rod, and a first elastic element is clamped between the actuating plate and the two limiting portions. The elastic extension and contraction direction of the first elastic element is parallel to the sliding path of the actuating rod.

[0022] By adopting the above technical solution, the sliding of the toggle lever relative to the toggle plate and the connection through the first elastic element are used to buffer and dampen the contact between the toggle lever and the push seat, thereby improving the stability of the forming cylinder movement.

[0023] Optionally, each of the two pushing mechanisms has a mounting base fixedly provided at its free end. The actuating plate is rotatably connected to the mounting base, and the rotation plane of the actuating plate is perpendicular to the transport direction. The mounting base is fixed with a first abutting part, and the actuating plate is fixed with a second abutting part. The second abutting part overlaps the upper side of the first abutting part.

[0024] By adopting the above technical solution, the process of placing the forming cylinder by the forklift involves placing the forming cylinder from top to bottom on the transport rail; however, to save energy when removing the forming cylinder, the forklift lifts the forming cylinder a relatively small distance. To accommodate the forklift's movement of removing the forming cylinder, the actuating plate is configured to rotate relative to the free end of the pushing mechanism and is connected to the first actuating part via a second abutment, allowing the actuating plate to rotate only upwards. This allows the actuating plate to be lifted during the forklift's removal of the forming cylinder, preventing the actuating plate and lever from interfering with the forklift's movement of removing the forming cylinder from the transport rail.

[0025] Optionally, each of the two transport tracks is equipped with a lifting cylinder. The lifting cylinder is located on the transport track at the position where the object to be transported is moved. The moving path of the driving end of the lifting cylinder is vertically arranged. The driving end of the lifting cylinder is equipped with a lifting column. The lifting column passes through and slides to the transport track. The actuating piece is located on the moving path of the lifting column.

[0026] By adopting the above technical solution, by setting a lifting cylinder and a lifting column at the position where the object to be transported is moved, the lifting cylinder drives the lifting column to rise, so as to realize the automatic lifting and lowering of the toggle plate, thereby improving the convenience and efficiency of operation.

[0027] Optionally, the lifting mechanism includes a lifting platform, a worm gear jack mounted on the lifting platform, and a lifting frame with the lifting end of the worm gear jack. The lifting platform is located below the transport rails and is horizontally arranged. The moving path of the lifting end of the worm gear jack is vertically arranged. The lifting frame is a horizontally arranged rectangular frame, and the moving path of the lifting frame is located between two transport rails.

[0028] By adopting the above technical solution, a worm gear jack drives the lifting frame to rise, thereby lifting the forming cylinder on the transport track until the forming cylinder comes into contact with the mounting plate of the laser printing equipment at the top. The lifting frame is a horizontally arranged rectangular frame, and the lifting device and printing substrate can be set within the vertical projection of the hollow part of the lifting frame, so that the printing substrate can be combined and separated from the forming cylinder through vertical displacement.

[0029] Optionally, the lifting end of the worm gear jack is fixedly connected to a lifting block. The upper surface of the lifting block is provided with an installation groove. The groove wall has a stepped shaft shape with the smaller end facing up. A fixing bolt is inserted and slidably connected inside the smaller end of the installation groove. The thread head of the fixing bolt is engaged in the larger end of the installation groove. The depth of the larger end of the installation groove is greater than the height of the thread head. The fixing bolt is also inserted and threadedly connected to the lifting frame. A second elastic element is clamped between the lifting block and the lifting frame.

[0030] By adopting the above technical solution, since the screw head of the fixing bolt is stuck in the large end of the mounting groove and the depth of the large end of the mounting groove is greater than the height of the screw head, when the worm gear jack drives the lifting frame to rise and abuts against the lower edge of the forming cylinder, the lifting end of the worm gear jack and the lifting block are able to move upward along the fixing bolt by a distance due to the reaction force. At the same time, the spring component buffers and dampens the movement of the lifting block relative to the lifting frame, so as to buffer and dampen the moment when the worm gear jack drives the lifting frame to rise and abuts against the forming cylinder, thereby reducing the possibility of the forming cylinder shifting due to the impact force generated at this moment.

[0031] Secondly, the 3D printer provided by this utility model adopts the following technical solution:

[0032] A 3D printer includes the aforementioned transport device for moving the cylinder.

[0033] In summary, this utility model has at least one of the following beneficial technical effects:

[0034] 1. The pushing mechanism drives the actuating component to push or pull the pushing seat, thereby moving the forming cylinder to the horizontal position for printing. After the forming cylinder reaches the printing position, the lifting mechanism lifts the forming cylinder until its upper edge contacts the laser printing equipment mounting plate on top. The lifting device then moves the printing substrate into the forming cylinder for printing. After printing, the printing substrate is lowered and removed. The lifting mechanism lowers the forming cylinder so that the pushing seat is placed back on the transport track. At this point, the pushing mechanism again drives the actuating component to push or pull the pushing seat, causing the forming cylinder to move horizontally away from the horizontal position for printing. Finally, a forklift removes the forming cylinder from the transport track. This process allows for quick placement and movement of the forming cylinder relative to the printing substrate, facilitating the retrieval of printed products and the loading of raw materials. Connecting this transport device to the production line makes management easier and improves printing efficiency.

[0035] 2. Several rolling elements can transform the sliding friction of the push seat on the transport track into rolling friction, reducing the frictional force that causes the push seat to move relative to the transport track, thereby improving the efficiency and stability of the forming cylinder moving on the transport track;

[0036] 3. The correction cylinders on the two transport tracks drive the correction rods to move toward the forming cylinder. The correction rods on both sides clamp the push seat of the forming cylinder. Then, through the rolling adjustment of the bearing rollers, the offset forming cylinder can be adjusted to be parallel to the transport direction, thus correcting the deviation. This allows the push mechanism to better drive the actuating part to push or pull the forming cylinder. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0044] This utility model discloses a transport device for moving a cylinder and a 3D printer. The 3D printer includes a transport device for moving the cylinder. (See reference...) Figure 1 and Figure 2 The transport device for moving the cylinder includes two transport tracks 1, both of which are rectangular plate structures. Both transport tracks 1 are horizontally arranged with their long sides parallel to each other, and the long side direction of the two transport tracks 1 forms the transport path. Several rolling elements 11 are provided on the upper surface of each of the two transport tracks 1; in this embodiment, the rolling elements 11 are ball bearings.

[0045] Reference Figure 1 , Figure 2 and Figure 3 Two push seats 3 are provided on each of the two outer walls of the forming cylinder 8 that are far apart from each other. The two push seats 3 on the same side are arranged at intervals in the horizontal direction. The push seats 3 have an L-shaped plate structure with the L-shaped opening facing away from the forming cylinder 8. Reinforcing ribs are fixedly connected to the two side plates of the push seats 3. The push seats 3 on both sides of the forming cylinder 8 are respectively placed on several rolling elements 11 of the two transport rails 1. The several rolling elements 11 can convert the sliding friction of the push seats 3 on the transport rails 1 into rolling friction, reduce the friction force of the push seats 3 moving relative to the transport rails 1, and thus improve the efficiency and stability of the forming cylinder 8 moving on the transport rails 1. The outer walls of the two outer walls of the forming cylinder 8 that are far apart from each other are also provided with lifting seats so that the forks of the forklift can lift the forming cylinder 8.

[0046] Reference Figure 2 and Figure 3Two transport tracks 1 are each equipped with a pushing mechanism 2, which can be an electric actuator, a pneumatic cylinder, or a hydraulic cylinder. In this embodiment, the pushing mechanism 2 is an electric actuator. The housing of the pushing mechanism 2 is mounted on the transport track 1, and the extension and retraction direction of the push rod of the pushing mechanism 2 is parallel to the transport path of the transport track 1. A toggle element 6 is provided at the front end of the push rod of each of the two pushing mechanisms 2. The toggle element 6 is located between two pushing seats 3 on the same side.

[0047] Reference Figure 1 A lifting mechanism 4 is installed below the two transport tracks 1. The lifting path of the lifting mechanism 4 is vertically arranged and located between the two transport tracks 1. The lifting mechanism 4 includes a lifting platform 41, a worm gear jack 42, and a lifting frame 43. The lifting platform 41 includes a support plate and four pillars, which are vertically fixed to the lower side of the support plate. The worm gear jack 42 is located on the upper side of the support plate. The worm gear jack 42 is a multi-unit worm gear jack 42 with multiple lifting ends. The lifting frame 43 is simultaneously fixedly installed on multiple lifting ends of the worm gear jack 42. The lifting frame 43 is a horizontally arranged rectangular frame, and its movement path is located between the two transport tracks 1. A lifting device 92 is installed below the two transport tracks 1. A printing substrate 9 is installed on the lifting end of the lifting device 92, and the lifting path of the printing substrate 9 vertically passes through the hollow part of the lifting frame 43.

[0048] A forklift places the push seats 3 on both sides of the forming cylinder 8 onto several rolling elements 11 on the sides of the two transport tracks 1, ensuring that the two push seats 3 on the same side of the forming cylinder 8 are positioned on either side of the actuating element 6. The push rod of the pushing mechanism 2 then moves the actuating element 6 along the transport path of the transport track 1. Since the actuating element 6 is located between the two push seats 3 on the same side of the forming cylinder 8, it pushes the two push seats 3 on the same side, thus pushing or pulling the forming cylinder 8 to the horizontal position for printing, i.e., the position of the lifting frame 43. After the forming cylinder 8 reaches the printing position, the worm gear lift 42 raises the lifting frame 43 until it contacts the forming cylinder 8, then lifts the forming cylinder 8 until its upper edge contacts the top laser printing equipment mounting plate 91, i.e., the forming plate reaches the vertical position for printing. At this point, the lifting device 92 passes the printing substrate 9 through the lifting frame 43 and moves it into the forming cylinder 8, allowing laser printing to begin.

[0049] After printing is complete, the lifting device 92 lowers and removes the printing substrate 9. The worm gear lift 42 drives the lifting frame 43 and the forming cylinder 8 to descend, allowing the push seat 3 to be placed back on the transport track 1. At this time, the pushing mechanism 2 drives the actuating component 6 to push or pull the push seat 3, causing the forming cylinder 8 to move horizontally away from the horizontal position of the printing process. Then, a forklift removes the forming cylinder 8 from the transport track 1. The above process allows for the rapid placement and movement of the forming cylinder 8 relative to the printing substrate 9, facilitating the retrieval of printed products and the loading of raw materials. Connecting this transport device to the production line makes management more convenient and improves printing efficiency.

[0050] Reference Figure 1 and Figure 4 To improve the stability of the lifting frame 43 when lifting the forming cylinder 8, a lifting block 44 is fixedly connected to the lifting end of the worm gear jack 42. The upper surface of the lifting block 44 has an installation groove 441, the groove wall of which has a stepped shaft shape with the smaller end at the top. A fixing bolt 442 is inserted into and slidably connected to the smaller end of the installation groove 441. The threaded head of the fixing bolt 442 is engaged in the larger end of the installation groove 441, and the depth of the larger end of the installation groove 441 is greater than the height of the threaded head. The fixing bolt 442 is also inserted into and threadedly connected to the lifting frame 43. A second elastic element 443 is held between the lifting block 44 and the lifting frame 43. In this embodiment, the second elastic element 443 is a disc spring.

[0051] Since the head of the fixing bolt 442 is locked in the large end of the mounting groove 441 and the depth of the large end of the mounting groove 441 is greater than the height of the bolt head, when the worm gear jack 42 drives the lifting frame 43 to rise and abuts against the lower edge of the forming cylinder 8, the lifting end of the worm gear jack 42 and the lifting block 44 are subjected to a reaction force and can move upward along the fixing bolt 442 by a certain distance. At the same time, the spring element buffers and dampens the movement of the lifting block 44 relative to the lifting frame 43, so as to buffer and dampen the moment when the worm gear jack 42 drives the lifting frame 43 to rise and abut against the forming cylinder 8, thereby reducing the possibility of the forming cylinder 8 shifting position due to the impact force generated at this moment.

[0052] Reference Figure 2 and Figure 5 To better push the two moving seats on the same side, the actuating component 6 includes an actuating plate 61 and an actuating rod 62. The actuating plate 61 is mounted on the front end of the push rod of the pushing mechanism 2 via a mounting base 21. The actuating rod 62 passes through the actuating plate 61, and its axis is parallel to the transport path and slides relative to the actuating plate 61. Limiting parts 621 are fixedly connected to both ends of the actuating rod 62. A first elastic element 63 is clamped between the actuating plate 61 and the two limiting parts 621. In this embodiment, the first elastic element 63 is a spring, and the elastic extension direction of the first elastic element 63 is parallel to the sliding path of the actuating rod 62.

[0053] The actuating plate 61 positions the actuating lever 62 between the two push seats 3. Because the axis of the actuating lever 62 is parallel to the transport direction, the distance between the actuating plate 61 and the two push seats 3 can be reduced, thereby reducing the stroke of the push mechanism 2 and improving efficiency. Furthermore, the sliding of the actuating lever 62 relative to the actuating plate 61 and its connection with the first elastic member 63 buffers and dampens the contact between the actuating lever 62 and the push seats 3, thus improving the smoothness of the movement of the forming cylinder 8.

[0054] Reference Figure 2 and Figure 5 The mounting base 21 is fixedly mounted on the push rod of the pushing mechanism 2. The actuating plate 61 is rotatably connected to the mounting base 21, and the rotation plane of the actuating plate 61 is perpendicular to the transport direction. The mounting base 21 is fixed with a first abutment part 211, and the actuating plate 61 is fixed with a second abutment part. The second abutment part 611 overlaps with the upper side of the second abutment part 611. When the second abutment part 611 overlaps with the first abutment part 211, the actuating plate 61 can be located between the two push bases 3 on the same side. Two transport tracks 1 are respectively fixedly equipped with lifting cylinders 7. The lifting cylinders 7 are located on the transport track 1 at the position where the forming cylinder 8 is moved away by the forklift. The moving path of the driving end of the lifting cylinder 7 is vertically arranged. The driving end of the lifting cylinder 7 is equipped with a lifting column 71. The lifting column 71 passes through and slides to the transport track 1, and the actuating plate 61 is located on the moving path of the lifting column 71.

[0055] The process of placing the forming cylinder 8 by the forklift involves placing the forming cylinder 8 from top to bottom on the transport track 1; however, to save energy when removing the forming cylinder 8, the forklift lifts the forming cylinder 8 a relatively small distance. To accommodate the forklift's movement of removing the forming cylinder 8, the actuating plate 61 is configured to rotate relative to the drive end of the pushing mechanism 2, and is engaged with the first actuating part 211 via the second abutment part 611, allowing the actuating plate 61 to rotate only upwards. This allows the actuating plate 61 to be lifted during the forklift's removal of the forming cylinder 8, preventing the actuating plate 61 and the actuating lever 62 from interfering with the forklift's movement of removing the forming cylinder 8 from the transport track 1. Furthermore, by installing a lifting cylinder 7 and a lifting column 71 at the location where the object to be transported is removed, the lifting cylinder 7 drives the lifting column 71 to rise, enabling automatic lifting and lowering of the actuating plate 61, improving operational convenience and efficiency.

[0056] Reference Figure 2When the forklift places the forming cylinder 8 on the transport track 1, the forming cylinder 8 may deviate relative to the transport direction. To correct the forming cylinder 8 relative to the transport path, a correction cylinder 5 is fixedly installed on the opposite edge of each of the two transport tracks 1. The movement paths of the drive ends of the correction cylinders 5 on both sides are perpendicular to the transport path. There are two correction cylinders 5 on the same side, and a correction rod 51 is fixed to the drive end of each correction cylinder 5. The length of the correction rod 51 is parallel to the transport path and its length is greater than the distance between the two push seats 3 on the same side. The forming cylinder 8 and the push seat 3 are located between the two correction rods 51. A bearing roller 31 is provided on the side of the push seat 3 away from the object to be transported. To ensure that the correction cylinders 5 can allow the correction rods 51 to reach a sufficient correction stroke, clearance grooves are provided on the outer edges of the two transport tracks 1, and the drive ends of the correction cylinders 5 are located in the clearance grooves.

[0057] The correction cylinders 5 on the two transport tracks 1 drive the correction rods to move toward the forming cylinder 8. The two correction rods clamp the push seat 3 of the forming cylinder 8. Then, through the rolling adjustment of the bearing rollers 31, the offset forming cylinder 8 can be adjusted to a state parallel to the transport direction, so that the push mechanism 2 can better drive the actuating part 6 to push or pull the forming cylinder 8.

[0058] Reference Figure 2 To facilitate more convenient and precise movement of the forming cylinder 8, a first position sensor 12 and a second position sensor 13 are installed on the transport track 1. Both the first position sensor 12 and the second position sensor 13 are electrically connected to the control end of the pushing mechanism 2. The first position sensor 12 is positioned at the horizontal position of the printing process, and the second position sensor 13 is positioned at the position to be moved of the forming cylinder 8. A first limiting block 121 and a second limiting block 131 are installed on the opposite sidewalls of the two transport tracks 1. The first limiting block 121 is located near the first position sensor 12 and on the side away from the second sensor 13, while the second limiting block 131 is located near the second position sensor 13 and on the side away from the first sensor 12.

[0059] After the forklift moves the forming cylinder 8 onto the transport track 1, the pushing mechanism 2 drives the forming cylinder 8 to the horizontal position for printing. At this time, the first position sensor detects this and controls the pushing mechanism 2 to close, so that the forming cylinder 8 is stably stopped at this position. When the pushing mechanism 2 drives the forming cylinder 8 to the position to be moved, the second position sensor detects this and controls the pushing mechanism 2 to close, so that the forming cylinder 8 is stably stopped at this position. When the first position sensor 12 controls the pushing mechanism to close, so that the forming cylinder 8 stops, the forming cylinder 8 will still move forward due to inertia. The first limit block 121 blocks and intercepts the forming cylinder 8, so that the forming cylinder 8 is accurately and stably stopped at the horizontal position for printing.

[0060] The implementation principle of a transport device for moving cylinders according to an embodiment of this utility model is as follows: A forklift places the push seats 3 on both sides of the forming cylinder 8 onto several rolling elements 11 on the sides of two transport tracks 1, so that the actuating plate 61 and the actuating rod 62 are located between the two push seats 3 on the same side. The correction cylinder 5 is activated, so that the correction rods 51 on both sides move toward the forming cylinder 8 to correct the deviation of the forming cylinder 8.

[0061] After the correction is completed, the push rod of the pushing mechanism 2 drives the actuating plate 61 to move along the transport path of the transport track 1. Since the actuating plate 61 is located between the two push seats 3 on the same side of the forming cylinder 8, the actuating rod 62 pushes the two push seats 3 on the same side to push or pull the forming cylinder 8, so as to drive the forming cylinder 8 to the horizontal position for printing, that is, the position of the lifting frame 43. After the forming cylinder 8 reaches the printing position, the worm gear lift 42 drives the lifting frame 43 to rise until it contacts the forming cylinder 8, and then lifts the forming cylinder 8 until the upper edge of the forming cylinder 8 contacts the top laser printing equipment mounting plate 91, that is, the forming plate reaches the vertical position for printing. At this time, the printing substrate 9 is passed through the lifting frame 43 and moved into the forming cylinder 8 by the lifting device 92, and laser printing can then be performed.

[0062] After printing is completed, the lifting device 92 lowers and removes the printing substrate 9. The worm gear lift 42 drives the lifting frame 43 and the forming cylinder 8 to descend so that the push seat 3 can be placed back on the transport track 1. At this time, the push mechanism 2 drives the actuating plate 61 and the actuating rod 62 to push or pull the push seat 3, so as to drive the forming cylinder 8 to move horizontally away from the horizontal position of printing.

[0063] After the forming cylinder 8 reaches the removal position, the lifting cylinder 7 drives the lifting column 71 to rise, causing the actuating plate 61 to rotate upward. Then, a forklift removes the forming cylinder 8 from the transport track 1. The above process enables the rapid placement and movement of the forming cylinder 8 relative to the printing substrate 9, facilitating the retrieval of printed products and the loading of raw materials. Connecting this transport device to the production line makes management more convenient and improves printing efficiency.

[0064] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
