Description

Technical Field

[0001] This invention belongs to the field of transformer insulation component processing technology, specifically relating to an insulating paper tube equal division marking device. Background Technology

[0002] Insulating paper tubes are important components in the insulation system of the transformer industry. The insulating paper tubes need to be divided into equal sections to facilitate the attachment of support strip components to the surface of the insulating paper tubes and subsequent work.

[0003] Currently, the marking of insulating paper tubes is done manually. The process involves measuring the diameter and circumference of the paper tube to determine the marking reference, using a measuring tape to mark the points vertically and horizontally, and then connecting the points vertically. There are no automated marking devices for insulating paper tubes on the market. Existing technology has the following shortcomings: 1. It is inconvenient to manually measure the diameter of paper tubes with a measuring tape (to check whether the paper tubes are qualified, and not to mark unqualified paper tubes). The largest insulating paper tubes produced in the workshop have a diameter of 2500mm and a height of 3200mm, which requires multiple people to operate and the efficiency of marking the equal division is very low.

[0004] 2. The manual division of points using a measuring tape is inaccurate. The reasons for the inaccuracy are as follows: (1) The diameter and height of the paper tube are too large, making operation inconvenient. (2) The paper tube has no internal support, and it will deform when the measuring tape is pulled. However, because the paper tubes vary greatly in size and have many specifications, it is too costly to make an internal support mold for each type of paper tube.

[0005] Third, there are many specifications for paper tubes, with the smallest having a diameter of only 800mm and a height of only 700mm. The number of equal divisions required for each specification of paper tube is different, and the process of dividing and marking is complex and requires highly skilled workers.

[0006] In summary, there is an urgent need to provide an insulating paper tube dividing line device that can equally divide the warp and weft lines, achieving full automation and high efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide an insulating paper tube equally divided marking device that can equally divide warp and weft lines, achieving full automation and high efficiency.

[0008] The above objective is achieved through the following technical solution: an insulating paper tube equally spaced marking device, comprising a base plate protection mechanism, a lower rotating inner support mechanism, an upper gantry inner support mechanism, and a marking mechanism. The lower rotating inner support mechanism includes a lower bearing rotating component, a lower radially opening and closing inner support assembly, a lower rotating support component, and a lower rotating drive assembly. The lower rotating support component is fixedly connected to the bottom plate protection mechanism. The lower bearing rotating component is disposed on the lower rotating support component. The lower rotating drive assembly is drively connected to the lower bearing rotating component and is used to drive the lower bearing rotating component to rotate around a first axis. The lower radially opening and closing inner support assembly is disposed on the lower bearing rotating component and can open and close radially along the lower bearing rotating component to adapt to the lower end inner support of insulating paper tubes of different diameters. The upper gantry inner support mechanism includes an upper gantry bearing frame, an upper bearing rotating component, an upper radially opening and closing inner support assembly, and an upper rotating drive assembly. The upper bearing rotating component is fixed on the upper gantry bearing frame and erected above the lower rotating inner support mechanism. The upper radially opening and closing inner support assembly is installed on the upper bearing rotating component. The upper rotating component can be radially opened and closed along the upper bearing rotating component to adapt to the upper inner support of paper tubes of different diameters. The upper rotating drive assembly is connected to the upper bearing rotating component and is used to drive the upper bearing rotating component to rotate around the second axis. The first axis and the second axis are coaxially arranged. The lower rotating drive assembly and the upper rotating drive assembly can be configured to drive the lower bearing rotating component to rotate synchronously with the upper bearing rotating component. The equal division marking mechanism includes a support column, a lifting mechanism, a translation mechanism and a marking component. The support column is arranged on the side of the lower rotating inner support mechanism and the upper gantry inner support mechanism and is fixed on the bottom plate protection mechanism. The translation mechanism is arranged on the support column through the lifting mechanism. The lifting mechanism is used to drive the translation mechanism to move vertically along the support column. The marking component is arranged on the translation mechanism and can be translated along the translation mechanism.

[0009] The insulating paper tube marking device of this invention can not only divide the warp lines equally, but also divide the weft lines equally through the combination of rotation and lifting, realizing full automation and high efficiency. It completely replaces the traditional inefficient and heavy manual tape measure and marking operations, and the production efficiency is improved by orders of magnitude. Furthermore, the fixing of the upper and lower inner support mechanisms eliminates the hidden danger of deformation of the thin paper tube due to external force, and provides a stable marking benchmark.

[0010] A further technical solution is that the lower radial tensioning inner support assembly includes a lower sliding member, a lower inner support member, and a storage trigger assembly. The lower sliding member is slidably installed on the inner side of the lower bearing rotating member. The lower inner support member is fixed on the lower sliding member and can move radially along the lower bearing rotating member with the lower sliding member to achieve tensioning and closing. The storage trigger assembly includes an elastic member and an abutment member. One end of the elastic member is connected to the inner support member, and the other end is fixed to the lower bearing rotating member. The abutment member is fixed on the lower bearing rotating member. When the lower sliding member moves towards the center of the lower bearing rotating member to a predetermined position, the abutment member abuts against the lower inner support member, driving the lower inner support member to switch to the collapsed storage position.

[0011] This invention, through its ingenious "automatic storage" design, fundamentally eliminates the physical interference of the internal support mechanism with forklift operations, enabling smooth automated loading and unloading. It avoids the need for operators to manually move or disassemble the internal support components for loading and unloading, eliminating the risk of human error and safety hazards, and facilitating the automation and intelligence of the entire process.

[0012] A further technical solution is that the marking component integrates a laser rangefinder, which is used to detect the perpendicularity of the insulating paper tube.

[0013] By seamlessly integrating the verticality detection function into the scribing equipment, the entire process of "detection-judgment-processing" is automated. It can automatically screen out unqualified products before the scribing process, avoiding unnecessary processing on unqualified products, saving production costs and ensuring the consistency of the final product quality.

[0014] A further technical solution is that the lower rotating inner support mechanism also includes a lower lifting auxiliary component. The lower lifting auxiliary component includes multiple sets of linear drive components and buffer lifting components. The multiple sets of linear drive components are evenly distributed along the circumference of the lower bearing rotating component and are fixedly installed on the frame structure below the lower bearing rotating component. The buffer lifting component is fixed to the output end of the linear drive component. The outer surface of the buffer lifting component is covered with a buffer layer. The linear drive component can extend and retract synchronously and drive the insulating paper tube to rise and fall through the buffer lifting component.

[0015] This ensures smooth lifting, prevents the paper tube from being scratched by the buffer layer, reduces the precision requirements for forklift drivers, simplifies the loading and unloading process, makes the handling of heavy workpieces simple and safe, reduces reliance on skilled workers, and also reduces labor intensity and safety risks.

[0016] A further technical solution is that the upper radially opening and closing inner support assembly includes an opening and closing drive component, a linkage component, an upper sliding component, a fixing component, and an upper inner support component. The opening and closing drive component is fixedly installed on the upper end of the upper bearing rotating component, and the output end of the opening and closing drive component is connected to the linkage component. The upper sliding component is slidably sleeved on the upper bearing rotating component, and the fixing component is fixed to the lower end of the upper bearing rotating component. The linkage component includes multiple hinge units, one end of which is connected to the upper sliding component, and the other end is connected to the sliding unit on the fixing component. The upper inner support component is fixed below the sliding unit of the fixing component. The opening and closing drive component drives the upper sliding component to rise and fall along the upper bearing rotating component, and the linkage component drives the sliding unit of the lower fixing component to move radially, thereby realizing the opening and closing of the upper inner support component.

[0017] In this way, a single drive source enables precise synchronization and a wide range of opening and closing of multiple internal support points. Its compact and reliable mechanical design ensures the high-performance realization of the upper internal support function.

[0018] A further technical solution is that the upper gantry inner support mechanism also includes a center-of-gravity balancing component and an upper rotating support component. The center-of-gravity balancing component is fixedly installed on one side of the top of the upper gantry bearing frame and is used to adjust the overall center of gravity of the upper gantry inner support mechanism. The upper rotating support component is a bearing assembly, fixedly installed below the other side of the top of the gantry frame. The outer side of the upper rotating support component has a flange portion, which is engaged with the upper rotating support component, so that the upper rotating support component can be rotatably supported below the gantry frame through the upper rotating support component. The upper rotating drive assembly includes a rotary motor, a reducer, and a meshing transmission component. The rotary motor is connected to the reducer, and the meshing transmission component includes two meshing transmission units. One transmission unit is connected to the output end of the reducer, and the other transmission unit is fixed to the upper end of the upper rotating support component and is used to drive the upper rotating support component to rotate.

[0019] A further technical solution is that the vertical end of the upper gantry bearing frame is slidably connected to the supporting column, and the upper gantry bearing frame can be raised and lowered along the vertical guide rail of the supporting column.

[0020] A further technical solution is that the supporting columns are symmetrically arranged on both sides of the lower rotating inner support mechanism, and the lifting mechanism includes a vertical power source, a vertical deceleration unit, a vertical transmission component and a vertical guide component. The vertical power source is connected to the vertical deceleration unit, the vertical transmission component is connected to the output end of the vertical deceleration unit, and the vertical guide component is arranged vertically along the supporting columns.

[0021] A further technical solution is that the translation mechanism includes a mounting base, a lateral power source, a lateral transmission component, and a lateral guide component. The lateral power source is connected to the lateral transmission component, the lateral guide component is arranged horizontally on the mounting base of the translation mechanism, and the mounting base is fixedly connected to the vertical transmission component.

[0022] A further technical solution is that both the upper and lower inner support members are made of non-metallic materials. That is, the push plate and the lower stop finger are made of non-metallic materials to avoid contaminating the insulating paper tube during the inner support operation.

[0023] Compared to existing technologies, the grading process for insulating paper tubes in this invention represents a leap from manual operation to fully automated, high-precision processing, offering the following technical advantages: (1) By using the synchronous rotating inner support mechanism, the inefficient and cumbersome manual scribing is completely replaced, solving the fundamental problems of deformation of large thin wallpaper tubes due to lack of inner support and inaccurate manual scribing. Production efficiency is increased by dozens of times, and scribing accuracy reaches a level that cannot be achieved by manual scribing. (2) The insulating paper tube dividing marking device of the present invention can not only divide the warp lines equally, but also divide the weft lines equally through the combination of rotation and lifting, realizing full automation and high efficiency, completely replacing the traditional inefficient and heavy manual tape measure and marking operations, and improving production efficiency by orders of magnitude.

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings. This description is merely illustrative and explanatory, and should not be construed as limiting the scope of protection of the present invention. Furthermore, those skilled in the art can combine the features in the embodiments described herein and in different embodiments according to the description in this document.

[0028] The embodiments of the present invention are as follows, with reference to Figures 1-8 A marking device for dividing insulating paper tubes includes a base plate protection mechanism 1, a lower rotating inner support mechanism 2, an upper gantry inner support mechanism 4, and a marking mechanism 3. The lower rotating inner support mechanism 2 includes a lower bearing rotating component 202, a lower radially opening and closing inner support assembly, a lower rotating support component 209, and a lower rotating drive assembly. The lower rotating support component 209 is fixedly connected to the bottom plate protection mechanism 1. The lower bearing rotating component 202 is disposed on the lower rotating support component 209. The lower rotating drive assembly is driven by the lower bearing rotating component 202 and is used to drive the lower bearing rotating component 202 to rotate around a first axis. The lower radially opening and closing inner support assembly is disposed on the lower bearing rotating component 202 and can be radially opened and closed along the lower bearing rotating component 202 to adapt to the lower end inner support of insulating paper tubes 5 of different diameters. The upper gantry inner support mechanism 4 includes an upper gantry bearing frame 401, an upper bearing rotating component, an upper radially opening and closing inner support assembly, and an upper rotating drive assembly. The upper bearing rotating component is fixed on the upper gantry bearing frame 401 and erected above the lower rotating inner support mechanism 2. The upper radially opening and closing inner support assembly is disposed on the lower bearing rotating component 209. The inner support assembly is installed on the upper bearing rotating member and can open and close radially along the upper bearing rotating member to adapt to the upper inner support of paper tubes of different diameters. The upper rotation drive assembly is connected to the upper bearing rotating member and is used to drive the upper bearing rotating member to rotate around the second axis. The first axis and the second axis are coaxially arranged. The lower rotation drive assembly and the upper rotation drive assembly can be configured to drive the lower bearing rotating member 202 to rotate synchronously with the upper bearing rotating member. The equal division marking mechanism 3 includes a support column, a lifting mechanism, a translation mechanism, and a marking component. The support column is arranged on the side of the lower rotating inner support mechanism 2 and the upper gantry inner support mechanism 4 and is fixed on the bottom plate protection mechanism 1. The translation mechanism is arranged on the support column through the lifting mechanism. The lifting mechanism is used to drive the translation mechanism to move vertically along the support column. The marking component is arranged on the translation mechanism and can be translated along the translation mechanism.

[0029] In the specific application of this invention, such as Figure 1 The base plate protection mechanism 1 serves as the foundation of the entire device and is fixed to the floor of the production workshop. For example... Figure 3 and Figure 4 The lower rotating support 209 is a flat bearing, which is pressed into the bearing groove of the base plate protection mechanism 1 to prevent the lower rotating support 209 from moving. A channel steel profile is welded below the lower bearing rotating component 202, and a flange ring is welded on the channel steel profile. The flange is clipped onto the lower rotating support 209, so that the lower rotating support 209 becomes the support for the lower bearing rotating component 202.

[0030] like Figure 3 and Figure 4The lower rotation drive assembly includes a hollow rotating platform 210 and a hollow lower rotation motor 211. The hollow rotating platform 210 is installed at the center of the base plate protection mechanism 1 and is connected to the lower bearing rotating component 202 via a hollow connecting shaft 208. The hollow lower rotation motor 211 is mounted on the hollow rotating platform 210, which serves as the power source for rotation. The lower rotation support component 209 provides support. The centrally located hollow rotating platform 210 allows for the use of gears with a smaller module, resulting in smaller gear backlash and higher rotational precision control.

[0031] Initially, the supporting component of the lower radial opening and closing inner support assembly is in a retracted state. The operator uses a forklift to lift the insulating paper tube 5 to be marked to the center area of ​​the lower bearing rotating component 202. The lower radial opening and closing inner support assembly begins to operate, driving the supporting component to move radially outward along the lower bearing rotating component 202, firmly supporting the lower end of the paper tube from the inside. Simultaneously, the upper radial opening and closing inner support assembly of the upper gantry inner support mechanism 4 operates synchronously, driving its supporting component to open radially, firmly supporting the upper end of the paper tube from the inside. At this point, the paper tube is vertically fixed by the upper and lower inner support mechanisms, achieving a stable shape and laying the foundation for high-precision marking.

[0032] Then, the equal division and marking operation is performed. The control system of the device controls the coordinated action of each mechanism according to the preset program to achieve two marking modes: Meridian (busbar) marking pattern: The lifting mechanism drives the translation mechanism and the marking component to rise to the starting height for marking. The lower rotation drive assembly and the upper rotation drive assembly rotate synchronously, causing the paper tube to rotate by an equal angle and then pause. Each time it pauses, the translation mechanism drives the marking component to move towards the surface of the paper tube and perform marking (such as inkjet printing), and then retracts. This process is repeated until the warp of the entire circumference is completed.

[0033] Latitude (circular) drawing pattern: The lifting mechanism positions the marking component at the bottom of the paper tube. The lower rotation drive assembly and the upper rotation drive assembly rotate synchronously and continuously, while the marking component continues to work, marking the first loop. Subsequently, the lifting mechanism gradually raises the marking component by a set height, and the paper tube rotates in the opposite direction to mark the second loop. This process is repeated until all loops are completed.

[0034] Both the lower and upper rotation drive components can be driven by servo motors. The control system sends synchronization commands to the two servo motors and performs real-time comparison and correction through the encoders built into the motors to ensure that the lower bearing rotating component 202 and the upper bearing rotating component always maintain precise synchronous rotation, effectively preventing the paper tube from twisting and deforming during the marking process.

[0035] After the marking is completed, the upper and lower inner support components retract and reset, releasing the paper tube. The forklift can then remove the processed paper tube, and the equipment is ready for the next work cycle.

[0036] The lower rotary drive assembly preferably uses a hollow rotary platform 210 as the drive core, and the lower rotary support 209 includes a plane bearing for load bearing. This combination of "precision drive and rough support" has smaller gear backlash and higher rotary indexing accuracy compared to traditional gear ring or worm gear structures.

[0037] The marking component is preferably an inkjet head 310. The translation mechanism can precisely control the distance between the inkjet head 310 and the surface of the paper tube to ensure clear and consistent markings.

[0038] The radial opening and closing function of the lower and upper radial opening and closing inner support components allows it to accommodate various paper tubes with diameters ranging from 800 mm to 2500 mm.

[0039] The insulating paper tube marking device of this invention can not only divide the warp lines equally, but also divide the weft lines equally through the combination of rotation and lifting, realizing full automation and high efficiency. It completely replaces the traditional inefficient and heavy manual tape measure and marking operations, and the production efficiency is improved by orders of magnitude. Furthermore, the fixing of the upper and lower inner support mechanisms eliminates the hidden danger of deformation of the thin paper tube due to external force, and provides a stable marking benchmark.

[0040] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 3 and Figure 4 The lower radial tensioning inner support assembly includes a lower sliding member 204, a lower inner support member, and a storage trigger assembly. The lower sliding member 204 is slidably mounted on the inner side of the lower bearing rotating member 202. The lower inner support member is fixed on the lower sliding member 204 and can move radially along the lower bearing rotating member 202 with the lower sliding member 204 to achieve tensioning and closing. The storage trigger assembly includes an elastic member and an abutment member. One end of the elastic member is connected to the inner support member, and the other end is fixed to the lower bearing rotating member 202. The abutment member is fixed on the lower bearing rotating member 202. When the lower sliding member 204 moves towards the center of the lower bearing rotating member 202 to a predetermined position, the abutment member abuts against the lower inner support member, driving the lower inner support member to switch to the collapsed storage position.

[0041] In practical applications, a lower sliding member 204 is installed inside the channel steel profile welded below the lower bearing rotating member 202, and the sliding member is equipped with a lower inner support member. like Figure 3 and Figure 4The lower sliding member 204 is specifically a linear module, which includes a slidable slider. The lower inner support member is specifically a lower stop finger 206, which is hinged to the lower sliding member 204 via a pivot, allowing it to rotate within a certain angle range. The elastic member is specifically a tension spring 205, one end of which is connected to the lower stop finger 206, and the other end is fixed to the lower bearing rotating member 202. Under the tension of the spring, the lower stop finger 206 is held in an upright working position perpendicular to the inner wall of the paper tube by default. The abutment member is specifically a pressure finger 207, which is fixedly installed on the lower bearing rotating member 202. Its position is precisely calculated and located above the path of the lower sliding member 204 moving towards the center.

[0042] Internal support action (tension): When it is necessary to tighten the paper tube, the control system drives the lower sliding member 204 to move radially outward along the lower bearing rotating member 202. Due to the tension of the tension spring 205, the lower stop finger 206 remains upright and finally firmly presses against the lower inner wall of the paper tube from the inside.

[0043] Inner support retraction and automatic storage (closing and storage): When the marking is completed and the paper tube needs to be removed, the control system drives the lower sliding member 204 to move inward (towards the center of the equipment).

[0044] During the movement, when the lower slider 204 carries the lower stop finger 206 to a predetermined position (i.e., the extreme position near the center), the back or a specific part of the lower stop finger 206 will contact and abut against the fixed pressure finger 207. As the lower slider 204 continues to move inward, the pressure finger 207 acts as a fixed inclined plane or lever, forcing the lower stop finger 206 to overcome the tension of the tension spring 205 and rotate downward about its hinge axis, thereby switching from the upright working position to the folded storage position. In this position, all the lower stop fingers 206 lie flat on or below the surface of the lower supporting rotating member 202, with their tops lower than the bottom of the paper tube.

[0045] When the lower stop finger 206 is in the collapsed and retracted position, its space occupation in the vertical and radial directions is minimized. This allows the forklift forks to extend unimpeded under the paper tube, or to place the paper tube directly on the lower bearing rotating component 202, perfectly solving the interference problem between the internal support mechanism and logistics handling tools.

[0046] This invention, through its ingenious "automatic storage" design, fundamentally eliminates the physical interference of the internal support mechanism with forklift operations, enabling smooth automated loading and unloading. It avoids the need for operators to manually move or disassemble the internal support components for loading and unloading, eliminating the risk of human error and safety hazards, and facilitating the automation and intelligence of the entire process.

[0047] like Figure 4The lower bearing rotating component 202 is covered with a bakelite pad 203 to prevent the insulating paper tube 5 from coming into contact with the metal and causing contamination.

[0048] like Figure 3 The rotating internal support mechanism includes a support frame 201, which is installed on the base plate protection mechanism 1 to protect the internal mechanism and facilitate the feeding of paper tubes.

[0049] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 6 The marking component integrates a laser rangefinder 311, which is used to detect the verticality of the insulating paper tube 5.

[0050] The laser rangefinder 311 and the marking component are integrated as a whole unit, driven by the translation mechanism and the lifting mechanism. The detection logic of the laser rangefinder 311 is as follows: after the lower radial tensioning inner support assembly fixes the lower end of the insulating paper tube, the laser rangefinder 311 moves vertically up and down along the insulating paper tube with the marking component, and collects the distance data between itself and the side wall of the insulating paper tube in real time; after the lower bearing rotating component 202 drives the insulating paper tube to rotate by a preset angle, the laser rangefinder 311 repeats the above lifting detection process to complete the multi-directional verticality detection and screen qualified insulating paper tubes for subsequent marking.

[0051] By seamlessly integrating the verticality detection function into the scribing equipment, the entire process of "detection-judgment-processing" is automated. It can automatically screen out unqualified products before the scribing process, avoiding unnecessary processing on unqualified products, saving production costs and ensuring the consistency of the final product quality.

[0052] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 5 The lower rotating inner support mechanism 2 also includes a lower lifting auxiliary component, which includes multiple sets of linear drive components and buffer lifting components. The multiple sets of linear drive components are evenly distributed along the circumference of the lower bearing rotating component 202 and are fixedly installed on the frame structure below the lower bearing rotating component 202. The buffer lifting component is fixed to the output end of the linear drive component. The outer surface of the buffer lifting component is covered with a buffer layer. The linear drive component can extend and retract synchronously and drive the insulating paper tube to rise and fall through the buffer lifting component.

[0053] In practical applications, a frame structure is welded below the lower bearing rotating component 202, and a linear drive component is installed on the frame structure. The linear drive component is specifically implemented as multiple lifting cylinders 212. These cylinders are preferably double-acting cylinders or cylinders with self-locking function to ensure the stability and safety of the lifting position. The buffer lifting component is specifically a rubber-coated lifting rod 213, the rod body of which has sufficient structural strength to bear the weight of the paper tube, and the buffer layer wrapped on its outer surface is preferably an elastic material such as rubber or polyurethane to prevent scratching or bumping the inner wall or end face of the paper tube. A total of four sets (eight) of lifting cylinders 212 are evenly distributed on the support frame 201 below the lower bearing rotating component 202. This circumferentially evenly distributed layout ensures the balance of force during the lifting process and prevents the paper tube from tilting.

[0054] Before the paper tube is loaded, the piston rods of all lifting cylinders 212 are in the retracted state, and the rubber-coated lifting rod 213 is lowered to the lowest point, leaving enough operating space for the forklift forks.

[0055] When the paper tube needs to be lifted for loading: The forklift transports the large insulating paper tube to the top of the equipment and roughly places it above the lowest position of the rubber-coated lifting rod 213. The control system controls all lifting cylinders 212 to operate synchronously, and their piston rods extend together, lifting the entire paper tube smoothly and vertically through the rubber-coated lifting rod 213. The paper tube is lifted to a height slightly higher than the top of the lower stop finger 206 when it is in the upright position. Subsequently, the internal support fixing and lifting and lowering are performed: The lower radial opening and closing internal support assembly operates, and the lower stop finger 206 opens radially to below the inner wall of the paper tube. The lifting cylinders 212 simultaneously lower a short distance, so that the weight of the paper tube is completely supported by the lower stop finger 206. At this time, the rubber-coated lifting rod 213 is no longer in contact with the bottom of the paper tube or only maintains slight contact, and no longer bears weight to avoid affecting the rotation of the paper tube. After the marking process is completed, the lifting cylinder 212 rises again synchronously, pressing against the bottom of the paper tube and "catching" it from the lower stop finger 206. Then the lower stop finger 206 is retracted, and finally the lifting cylinder 212 descends to place the paper tube onto the forklift forks, completing the unloading.

[0056] This ensures smooth lifting, prevents the paper tube from being scratched by the buffer layer, reduces the precision requirements for forklift drivers, simplifies the loading and unloading process, makes the handling of heavy workpieces simple and safe, reduces reliance on skilled workers, and also reduces labor intensity and safety risks.

[0057] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 7 and Figure 8The upper radially opening and closing inner support assembly includes an opening and closing drive component, a linkage component, an upper sliding component, a fixing component, and an upper inner support component. The opening and closing drive component is fixedly installed on the upper end of the upper bearing rotating component, and the output end of the opening and closing drive component is connected to the linkage component. The upper sliding component is slidably sleeved on the upper bearing rotating component, and the fixing component is fixed to the lower end of the upper bearing rotating component. The linkage component includes multiple hinge units, one end of which is connected to the upper sliding component, and the other end is connected to the sliding unit on the fixing component. The upper inner support component is fixed below the sliding unit of the fixing component. The opening and closing drive component drives the upper sliding component to rise and fall along the upper bearing rotating component, and the linkage component drives the sliding unit of the lower fixing component to move radially, thereby realizing the opening and closing of the upper inner support component.

[0058] In specific applications, such as Figure 7 and Figure 8 The opening and closing drive components specifically include: an upper inner support opening and closing motor 406, a lower inner support opening and closing reducer 407, and an upper inner support opening and closing lead screw 411; an upper bearing rotating component: specifically a hollow thick-walled tube 410; an upper sliding component: specifically an upper hollowed-out disk 417, which is slidably fitted onto the hollow thick-walled tube 410 via a central sliding sleeve 416. A fixing component: specifically a lower hollowed-out disk 423, which is fixedly installed at the bottom of the hollow thick-walled tube 410. A linkage assembly: each hinge unit consists of hinge one 418 and hinge two 419. A sliding unit on the fixing component: specifically a slider installed on the radial guide rail of the lower hollowed-out disk 423, which has a fulcrum two 421. An upper inner support component: specifically a push plate 422, fixed below the sliding unit. A central fulcrum 424 is installed near the central flange of the lower hollow plate 423. A fulcrum 1 420 is installed on the slider of the guide rail on the upper hollow plate 417. A hinge 1 418 connects the central fulcrum 424 and the fulcrum 1 420. A fulcrum 2 421 is installed on the slider of the guide rail on the lower hollow plate 423. A hinge 2 419 connects the fulcrum 1 420 and the fulcrum 2 421. A push plate 422 is installed below the fulcrum 2 421, so that the opening and closing of the push plate 422 can be achieved by the lifting and lowering of the upper hollow plate 417.

[0059] like Figure 7 and Figure 8A sealing plate is installed at the upper end of the hollow thick-walled tube 410, and an upper inner support tensioning reducer 407 is installed on the sealing plate. An upper inner support tensioning motor 406 is installed on the upper inner support tensioning reducer 407. The upper inner support tensioning motor 406 is connected to the upper inner support tensioning screw 411 via a coupling. A flange is welded to the inner wall of the hollow thick-walled tube 410, and a bearing 412 is installed on the flange. The bearing 412 is used to fix the upper end of the upper inner support tensioning screw 411. A lower hollow plate 423 is installed at the lower part of the hollow thick-walled tube 410. There is a flange in the center of the lower hollow plate 423, and a bearing 413 is installed on the flange. The bearing 413 is used to fix the end of the upper inner support tensioning screw 411. The upper inner support tensioning screw 411 has a screw nut 414, and a T-flange 415 is installed on the upper end of the screw nut 414. The hollow thick-walled tube 410 has grooves on both sides, and the upper end of the T-flange 415 extends from the grooves on both sides of the hollow thick-walled tube 410 and connects to the upper hollow plate 417. A sliding sleeve 416 is installed at the center of the flange of the upper hollow plate 417, and the hollow thick-walled tube 410 passes through the sliding sleeve 416, thereby realizing the raising and lowering of the upper hollow plate 417.

[0060] The transmission process of the opening and closing motion is as follows: The upper inner support tensioning motor 406 starts, driving the upper inner support tensioning screw 411 to rotate. The screw nut 414 on the upper inner support tensioning screw 411 is connected to the upper hollow plate 417 through the T-flange 415. Therefore, the rotational motion of the screw is converted into the precise lifting and lowering motion of the upper hollow plate 417 along the hollow thick-walled tube 410. When the upper hollow plate 417 moves downward, it pulls the hinge 1 418 connected to it. The other end of the hinge 1 418 pushes the fulcrum 2 421. Since the fulcrum 2 421 is installed on the radial guide rail of the lower hollow plate 423, and the hinge 1 418 and the hinge 2 419 form a scissor linkage mechanism, this downward pulling and pushing force is cleverly converted into pushing the fulcrum 2 421 and the slider it is located on to move radially outward along the guide rail of the lower hollow plate 423.

[0061] Conversely, when the upper hollowed-out plate 417 moves upward, the reverse action of the linkage mechanism will pull the second fulcrum 421 to move radially inward.

[0062] Finally, the radial outward movement of the slider directly drives the push plate 422 fixed below it to move outward as well, thereby tightening the upper end of the paper tube from the inside and realizing "opening"; the radial inward movement of the slider drives the push plate 422 to retract and disengage from the paper tube, realizing "closing".

[0063] In this way, a single drive source enables precise synchronization and a wide range of opening and closing of multiple internal support points. Its compact and reliable mechanical design ensures the high-performance realization of the upper internal support function.

[0064] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 7and Figure 8 The upper gantry inner support mechanism 4 also includes a center-of-gravity balancing component 402 and an upper rotating support component. The center-of-gravity balancing component 402 is fixedly installed on one side of the top of the upper gantry bearing frame 401 and is used to adjust the overall center of gravity of the upper gantry inner support mechanism 4. The upper rotating support component is a bearing assembly, which is fixedly installed below the other side of the top of the gantry frame. The outer side of the upper rotating support component has a flange portion, which is engaged with the upper rotating support component, so that the upper rotating support component can be rotatably supported under the gantry frame through the upper rotating support component. The upper rotating drive assembly includes a rotary motor (upper inner support rotary motor 403), a reducer (upper inner support rotary reducer 404), and a meshing transmission component (upper inner support rotary gear set 405). The rotary motor is connected to the reducer component, and the meshing transmission component includes two meshing transmission units. One transmission unit is connected to the output end of the reducer component, and the other transmission unit is fixed to the upper end of the upper rotating support component and is used to drive the upper rotating support component to rotate.

[0065] The center of gravity balance component 402 is made of metal blocks and is fixedly installed on the top of the upper gantry bearing frame 401 on the side (i.e., the rear side) away from the center of the equipment.

[0066] Because the entire weight of the upper radial tensioning inner support assembly is concentrated on the front side of the gantry frame, the center of gravity of the entire mechanism will tilt forward significantly. This will not only generate a huge overturning moment on the lead screw and guide rail of the lifting mechanism, affecting its lifespan and accuracy, but may also cause the lifting mechanism to jam. The counterweight is added to the rear to adjust the overall center of gravity of the entire upper gantry inner support mechanism 4 back to near the mechanical center of the lifting mechanism, thereby ensuring smooth and stable lifting movement and protecting the lead screw and guide rail from abnormal loads.

[0067] The upper gantry support frame 401 has two mounting positions at the top, one at the front and one at the back. The rear mounting position is equipped with a center of gravity balance component 402, which is used to adjust the center of gravity of the upper gantry inner support mechanism 4.

[0068] like Figure 8The upper inner support rotating motor 403 and the sealing bearing flange 408 are installed below the front mounting position. The sealing bearing flange 408 contains two upper inner support rotating bearings 409. The upper inner support rotating motor 403 is decelerated by the upper inner support rotating reducer 44 and then welded to the outside of the hollow thick-walled tube 410 with a flange. This flange is clamped by the two upper inner support rotating bearings 409, and the tube wall passes through the two upper inner support rotating bearings 409, thus securing it. The upper inner support rotating gear set 405 has two gears. One gear is installed at the upper end of the hollow thick-walled tube 410, and the other gear is installed at the end of the upper inner support rotating motor 403, thereby enabling independent rotation of the upper gantry inner support mechanism 4 (however, due to the limited flexibility of the flexible cable of the upper inner support opening and closing motor 406, the upper gantry inner support mechanism 4 cannot rotate continuously in the same direction for more than 360°).

[0069] Based on the above embodiments, in another embodiment of the present invention, such as 1, the vertical end of the upper gantry bearing frame 401 is slidably connected to the supporting column, and the upper gantry bearing frame 401 can be raised and lowered along the vertical guide rail of the supporting column.

[0070] The upper gantry support frame 401 is U-shaped, with two feet mounted on the sliders of the gantry lifting guide rail 315 supporting the column. Its bottom is connected to the screw nut 414 of the gantry lifting screw 314. The gantry lifting motor 312 drives the screw nut 414 of the lifting screw through the gantry lifting reducer 313, thereby driving the upper gantry inner support mechanism 4 to rise and fall. The lifting function of the upper gantry inner support mechanism 4 allows it to accommodate various paper tubes with heights ranging from 700mm to 3200mm.

[0071] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 1 The supporting columns are symmetrically arranged on both sides of the lower rotating inner support mechanism 2. The lifting mechanism includes a vertical power source, a vertical deceleration unit, a vertical transmission component, and a vertical guide component. The vertical power source is connected to the vertical deceleration unit, the vertical transmission component is connected to the output end of the vertical deceleration unit, and the vertical guide component is arranged vertically along the supporting columns.

[0072] like Figure 6 The vertical power source is specifically the inkjet head lifting motor 302 that drives the inkjet head 310 to lift. The vertical reduction unit is the inkjet head lifting reducer 303 connected to the inkjet head lifting motor 302. The vertical transmission component is specifically the inkjet head lifting lead screw 304, the bottom end of which is connected to the output end of the inkjet head lifting reducer 303 through a coupling. The vertical guide component is specifically the inkjet head lifting guide rail 305, which is installed on the support column.

[0073] The symmetrical layout of the supporting columns forms a stable gantry structure, which can effectively resist various forces and torques generated during equipment operation, providing a solid geometric benchmark for high-precision scribing and preventing scribing errors caused by frame deformation.

[0074] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 6 The translation mechanism includes a mounting base, a lateral power source, a lateral transmission component, and a lateral guide component. The lateral power source is connected to the lateral transmission component. The lateral guide component is arranged horizontally on the mounting base of the translation mechanism. The mounting base is fixedly connected to the vertical transmission component.

[0075] In specific applications, such as Figure 6 The mounting base is specifically an adapter plate 306. The adapter plate 306 is fixedly connected to the vertical transmission component (inkjet head lifting screw 304) via a lead screw nut 414, and is also connected to the vertical guide component (inkjet head lifting guide rail 305) via a slider, thereby being suspended on the lifting mechanism.

[0076] The lateral power source is specifically a servo motor integrated within the inkjet head translation module 307. The lateral transmission components and lateral guide components are also integrated inside this module, typically precision ball screws or synchronous belts, as well as high-precision linear guides.

[0077] The motor of the translation module starts, driving the internal transmission mechanism to move the slider on it precisely in the horizontal direction (radially towards or away from the center of the device). The scribing component, i.e., the inkjet head 310, is fixed to the slider by the inkjet head mounting structure 308. Thus, precise and rapid forward and backward movement of the scribing component on the horizontal plane is achieved.

[0078] The translation mechanism gives the marking component the freedom of radial movement, allowing precise control of the distance between the inkjet head 310 and the paper tube surface, ensuring optimal inkjet effect and marking quality. It is also key to executing the automated action of "extending during marking and retracting during idle stroke".

[0079] Based on the above embodiments, in another embodiment of the present invention, both the upper inner support and the lower inner support are made of non-metallic materials. That is, the push plate 422 and the lower stop finger 206 are made of non-metallic materials to avoid contaminating the insulating paper tube during the paper tube support operation.

[0080] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
