Description

Technical Field

[0001] This utility model relates to the technical field of sculpture processing, specifically an automatic feeding mechanism for sculpture processing blanks. Background Technology

[0002] In the field of sculpture processing, especially when CNC carving or milling large blanks of stone, concrete, or other hard materials, it is usually necessary to transport the blanks from the storage area or loading area to the designated workstation of the processing equipment. Since sculpture blanks are often large in size and heavy in weight, and need to be stably positioned on the machine tool table in a specific posture (e.g., vertical) before processing, the handling and posture adjustment during the loading process become key links affecting the degree of automation and efficiency of processing.

[0003] Currently, common methods of loading blanks still largely rely on manual operation or general equipment such as cranes and forklifts for handling and flipping. These methods suffer from high labor intensity, low positioning accuracy, safety hazards, and poor automation continuity, making them unsuitable for the demands of modern mass production or high-efficiency manufacturing of sculptures. Although some automated conveyor lines have been applied in industrial production, they mostly focus on horizontal material transfer, often lacking efficient, compact, and reliable integrated solutions for automatic alignment and correction of blanks during transport, as well as for the specific angle (such as 90°) flipping and positioning required at the end.

[0004] Specifically, during the billet transport stage, if the billet's position shifts on the roller conveyor, it may cause jamming or abnormal posture during subsequent flipping or positioning, affecting the smoothness of the entire feeding process. During the flipping stage, a key technical challenge is how to achieve a smooth and precise transition of heavy billets from a horizontal conveying state to a vertical standing state without interfering with the transport mechanism, and how to effectively clamp and fix the flipped billets until they are removed by the feeding equipment. Existing technologies with flipping functions may have complex structures, occupy a large space, or be difficult to seamlessly connect and coordinate with the transport and feeding equipment of upstream and downstream processes. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide an automatic feeding mechanism for sculpture processing blanks, which solves the problems of centering, flipping and precise positioning in the automated feeding process of sculpture processing blanks.

The flipping component is arranged downstream of the transmission component, and the aligning component is arranged in the middle section of the transmission component.

[0007] The transmission assembly includes multiple sets of carrier rollers that are rotatably mounted on the mounting frame and arranged horizontally and evenly. Each set of carrier rollers operates synchronously, and the feeding assembly is arranged above the carrier rollers.

[0008] The flipping assembly includes a support frame plate, a positioning frame plate, connecting rods, a flipping cylinder, and a positioning cylinder. The support frame plate is rotatably mounted on the mounting frame. The positioning frame plate is arranged above the support frame plate and parallel to it. A baffle plate is fixedly connected to the downstream end of the support frame plate and is perpendicular to it. The connecting rods include multiple sets arranged in parallel. The two ends of each set of connecting rods are hinged to the support frame plate and the positioning frame plate, respectively. The support frame plate is matched with a portion of the support rollers and is set below the geometric apex of the support frame plate. The flipping cylinder and the positioning cylinder are poweredly connected to the support frame plate and the connecting rod, respectively.

[0009] Based on the above technical solutions, the following technical solutions are provided to ensure that the transmission component, the flipping component, and the material feeding component can be stably assembled on the mounting frame.

[0010] Both sides of the mounting frame are fixedly connected to lateral baffles that are perpendicular to the bearing roller. The bottom of the lateral baffles is fixedly connected to a transverse baffle arranged below the bearing roller. The bearing roller is rotatably installed between the two sets of lateral baffles.

[0011] Based on the above technical solutions, in order to ensure that each set of bearing rollers can operate stably in a synchronous manner, and at the same time avoid spatial motion interference between the bearing frame plate set below the geometric apex of the bearing roller and the cooperating bearing rollers, the following technical solutions are provided.

[0012] Each set of the bearing rollers has a drive sprocket fixedly connected to its end. The drive sprockets on two adjacent sets of bearing rollers are connected by a chain. The transmission assembly also includes a drive motor, which is fixedly installed on the outside of the side baffle. The end of one set of the bearing rollers is coaxially connected to the output shaft of the drive motor.

[0013] A clearance ring groove is provided around the periphery of some of the bearing rollers, and the bearing frame plate is arranged in the clearance ring groove when it is in a horizontal state.

[0014] Based on the above technical solutions, in order to ensure that the tilting cylinder and positioning cylinder can be stably assembled and achieve power connection with the bearing frame plate and connecting rod, while avoiding spatial motion interference with the bearing roller.

[0015] The two ends of the tilting cylinder are hinged to the support frame plate and the transverse baffle, respectively. The positioning cylinder is arranged on both sides of the support frame plate, and the two ends of the positioning cylinder are hinged to the support frame plate and the connecting rod, respectively.

[0016] The bearing rollers include roller A and roller B arranged coaxially, and the tilting cylinder is arranged between roller A and roller B.

[0017] Based on the above technical solutions, in order to ensure that the material feeding assembly can be stably assembled on the mounting frame and to achieve effective adjustment of the opening and closing gap, so as to provide material feeding processing for the conveyed billets, the following technical solutions are provided.

[0018] The feeding assembly includes two sets of symmetrically arranged guide plates and a guide roller rotatably mounted to the inner end of the guide plates. The guide plates are arranged on the bearing roller, and the outer ends of the guide plates are hinged to the inner wall of the lateral baffle. The two sets of guide plates run synchronously in opposite directions.

[0019] Based on the above technical solution, in order to ensure that the two sets of guide plates always maintain synchronous reverse operation and avoid interference with the bearing roller and the conveyed blank, the following technical solution is provided.

[0020] The feeding assembly also includes a guide shaft, a threaded rod, an adjusting motor, and a slide block. The guide shaft and the threaded rod are arranged parallel to each other and are rotatably mounted between the two sets of side baffles. Two sets of slide blocks are slidably mounted on the guide shaft. The geometric vertex of the bearing roller is higher than the guide shaft and the threaded rod. The threaded rod has two threaded grooves with opposite helical directions. The threaded grooves at both ends are screwed into the two sets of slide blocks respectively. The bottom of the guide plate has a strip-shaped guide groove. The slide block is fixedly connected to a pin that matches the corresponding strip-shaped guide groove. The adjusting motor is fixedly mounted on the outside of the side baffle and is coaxially fixedly connected to the threaded rod.

[0021] The beneficial effects of this utility model are: 1. This solution organically integrates three major functional modules: conveying, material alignment (centering and correction), and flipping. From material loading, conveying, automatic centering, end positioning to final flipping and standing, the entire process requires no manual intervention, achieving continuous and highly efficient automated operation. Each component operates sequentially through program control, ensuring smooth transitions and significantly improving the overall efficiency and production cycle of the sculpture processing production line.

[0022] 2. A transmission line composed of multiple sets of synchronously operating support rollers provides stable and continuous conveying power for the billet. The guide plate in the feeding assembly, which can be adjusted synchronously in opposite directions, automatically corrects any deviation of the billet during transmission, ensuring it travels along the centerline to the flipping station. This lays the foundation for subsequent precise positioning and flipping, avoiding jamming or flipping failure due to inaccurate positioning. The flipping assembly employs a parallelogram linkage mechanism, with a positioning cylinder driving the positioning frame plate downwards. Together with the support frame plate (which gradually participates during the flipping process), it forms a stable clamp, and then the flipping cylinder achieves a precise 90° flip. This process ensures secure clamping and smooth operation, effectively preventing heavy billets from shaking, slipping, or being damaged during flipping.

[0023] 3. When in a horizontal state, the support frame plate is embedded in the clearance groove of the support roller, ensuring that it does not affect the normal transfer of the billet when not in operation, resulting in a compact structure. The tilting cylinder is cleverly arranged between the segmented support rollers (roller A and roller B), and the positioning cylinder and connecting rod are hinged to both sides of the support frame plate. These designs make full use of the internal space of the equipment, effectively avoiding spatial motion interference between the actuators and the transmission components, and ensuring the reliability and safety of the mechanism's operation.

[0024] 4. The centering assembly is not only used for centering, but also can prevent subsequent billets from entering the flipping station through a closing action. This function ensures that when the flipping assembly adjusts the attitude of the current billet, subsequent billets will not rush in and cause interference or collisions, realizing isolation between stations and process interlocking, and improving the safety and continuity of the entire system operation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 An automatic feeding mechanism for sculpting blanks includes a mounting frame 1 and a transmission component 2, a flipping component 3, and a straightening component 4 assembled on the mounting frame 1. The flipping component 3 is located downstream of the transmission component 2, and the straightening component 4 is located in the middle of the transmission component 2.

[0029] The transmission assembly 2 includes multiple sets of carrier rollers 21 that are rotatably mounted on the mounting frame 1 and arranged horizontally and evenly. Each set of carrier rollers 21 operates synchronously, and the feeding assembly 4 is arranged above the carrier rollers 21.

[0030] The flipping assembly 3 includes a support frame plate 31, a positioning frame plate 32, a connecting rod 33, a flipping cylinder 34, and a positioning cylinder 35. The support frame plate 31 is rotatably mounted on the mounting frame 1. The positioning frame plate 32 is arranged above the support frame plate 31 and parallel to the support frame plate 31. A baffle plate 311 is fixedly connected to the downstream end of the support frame plate 31 and is perpendicular to the support frame plate 31. The connecting rod 33 includes multiple sets arranged in parallel. The two ends of each set of connecting rods 33 are hinged to the support frame plate 31 and the positioning frame plate 32, respectively. The support frame plate 31 is matched with a portion of the support rollers 21 and is set below the geometric apex of the support frame plate 31. The flipping cylinder 34 and the positioning cylinder 35 are poweredly connected to the support frame plate 31 and the connecting rod 33, respectively.

[0031] The mounting frame 1 provides stable assembly support for the transmission component 2, the flipping component 3, and the feeding component 4, ensuring their stable operation according to design requirements.

[0032] The transmission component 2 stably carries and transmits the sculpting blanks by means of a horizontally evenly arranged bearing roller 21 while maintaining synchronous operation. The blanks are loaded to the upstream end of the transmission component 2 by hoisting or transporting, and first pass through the material straightening component 4 under the drive of the bearing roller 21. The material straightening component 4 adjusts the opening and closing spacing according to the width of the blank, thereby ensuring that the blanks passing through the material straightening component 4 can be stably transmitted at the center position of the bearing roller 21.

[0033] In the initial stage, the flipping component 3 is in a horizontal position, while the baffle plate 311 is in a vertical position and extends beyond the geometric apex of the positioning roller. The billet is driven to the downstream end by the transmission component 2 in a horizontal manner. At this time, since the bearing frame plate 31 is designed to be lower than the bearing roller 21, it will not cause spatial interference to the normal feeding of the billet. After the billet comes into contact with the baffle plate 311, the billet is exactly between the bearing frame plate 31 and the positioning frame plate 32. At this time, the positioning cylinder 35 drives the connecting rod 33 to flip.

[0034] There are four sets of connecting rods 33, with two sets on each side of the bearing frame plate 31, so that the connecting rods 33, the bearing frame plate 31, and the positioning frame plate 32 form a parallelogram linkage mechanism, thereby driving the positioning frame plate 32 to move downward, so that the positioning frame plate 32 and the bearing frame plate 31 together clamp and position the blank.

[0035] Then, the tilting cylinder 34 is controlled to rotate, pushing the bearing frame plate 31, the positioning frame plate 32 and the clamped blank to rotate 90° as a whole, so that the blank, which was originally placed horizontally, is adjusted to a vertical arrangement, thus making it easier to clamp the vertical blank with the feeding equipment and transfer it to the positioning fixture of the engraving machine or CNC milling machine.

[0036] It should also be noted that after the billet passes through the feeding assembly 4 and is conveyed to the flipping assembly 3, the feeding assembly 4 is closed to prevent subsequent billets from continuing to be conveyed to the flipping assembly 3. This can prevent the continuous conveying of billets from affecting the normal operation of the flipping assembly 3 during the operation of the flipping assembly 3 in adjusting the attitude of the billet.

[0037] The aforementioned feeding equipment can adopt a dual-axis feeding mechanism or a multi-axis robotic arm. When a dual-axis feeding mechanism is adopted, the clamps on it can move in two dimensions, horizontal and vertical. The clamps can then hold the vertically arranged blanks and transfer them horizontally to the engraving machine or CNC milling machine. The vertical movement of the clamps can realize the lifting and lowering of the clamps, thereby enabling the blanks to be held below and then lifted to detach from the flipping component 3.

[0038] When using a multi-axis robotic arm for material feeding, the fixture is assembled to the movable end of the multi-axis robotic arm. The multi-axis robotic arm drives the fixture to run and clamp the blank, then transfers it to the positioning fixture set on the sculpting table or conveyor milling machine.

[0039] It should also be noted that, due to the design of the support frame plate 31 being lower than the geometric apex of the support roller 21, when the positioning frame plate 32 initially positions the billet, the support roller 21 and the positioning frame plate 32 are actually used to position the billet (at this time, the support frame plate 31 is designed to be lower than the support roller 21 and does not directly contact the billet). As the rotating cylinder 34 rotates and drives the support frame plate 31 to rotate upward, the support frame plate 31 gradually moves above the geometric apex of the support roller 21 and participates in the positioning of the billet. At this time, the positioning cylinder 35 further controls the positioning frame plate 32 to move towards the support frame plate 31 and makes the positioning frame plate 32 and the support frame plate 31 work together to effectively clamp the billet, so as to ensure that the billet can be stably rotated to a vertical state.

[0040] When the feeding equipment is in operation, after the clamps on it clamp the billet, the positioning cylinder 35 is controlled to move the positioning frame plate 32 away from the bearing frame plate 31 and cancel the clamping effect on the billet. After the billet is completely detached from the flipping component 3 by the feeding equipment, the flipping component 3 can be reset to the initial state without the billet limiting effect, so as to facilitate the posture adjustment of the next billet.

[0041] To ensure that the transmission component 2, the flipping component 3, and the material straightening component 4 can be stably assembled on the mounting frame 1, the following technical solution is provided.

[0042] Both sides of the mounting frame 1 are fixedly connected to lateral baffles 11 that are perpendicular to the bearing roller 21. The bottom of the lateral baffles 11 is fixedly connected to a transverse baffle 12 arranged below the bearing roller 21. The bearing roller 21 is rotatably installed between the two sets of lateral baffles 11.

[0043] The side baffles 11 provide stable support for the installation of the bearing roller 21, so that the end of the bearing roller 21 is assembled to the mounting frame 1 in a relative rotation manner through roller bearings. The transverse baffles 12 are fixedly connected to the two sets of side baffles 11, which not only improves the overall structural strength of the mounting frame 1, but also ensures the stability of the installation and operation of other components.

[0044] To ensure that each set of bearing rollers 21 can operate stably in a synchronous manner, and to avoid spatial motion interference between the bearing frame plate 31 located below the geometric vertices of the bearing rollers 21 and the cooperating bearing rollers 21, the following technical solution is provided.

[0045] Each set of bearing rollers 21 has a transmission sprocket 211 fixedly connected to its end. The transmission sprockets 211 on two adjacent sets of bearing rollers 21 are connected by a chain 212. The transmission assembly 2 also includes a drive motor 22, which is fixedly installed on the outside of the side baffle 11. The end of one set of bearing rollers 21 is coaxially connected to the output shaft of the drive motor 22.

[0046] A clearance ring groove 213 is provided around the periphery of some of the bearing rollers 21, and the bearing frame plate 31 is arranged in the clearance ring groove 213 when it is in a horizontal state.

[0047] Two sets of drive sprockets 211 are fixedly connected to the same end of each set of intermediate bearing rollers 21. The two sets of drive sprockets 211 are connected to the drive sprockets 211 on the adjacent sets of bearing rollers 21 via independent chains 212, thereby ensuring that each set of bearing rollers 21 always maintains the same speed and direction of operation. A support 13 is fixedly connected to the outside of the side baffle 11, and the drive motor 22 is fixedly installed on the support 13 to achieve stable installation. The drive motor 22 is a geared motor, which drives each set of bearing rollers 21 to maintain a low-speed stable operation, thereby driving the billet carried on them to be fed stably.

[0048] Multiple bearing rollers 21 located at the downstream end of the mounting frame 1 are provided with relief ring grooves 213 that are arranged relative to the bearing frame plate 31. When the bearing frame plate 31 is flipped downward to a horizontal position, it can fall into the relief ring grooves 213 and be below the geometric apex of the bearing roller 21, thus avoiding spatial motion interference between the billet and the bearing frame plate 31 during the transfer of the billet on the bearing roller 21.

[0049] To ensure that the tilting cylinder 34 and positioning cylinder 35 can be stably assembled and achieve power connection with the bearing frame plate 31 and connecting rod 33, while avoiding spatial movement interference with the bearing roller 21.

[0050] The two ends of the tilting cylinder 34 are hinged to the support frame plate 31 and the transverse baffle 12, respectively. The positioning cylinder 35 is arranged on both sides of the support frame plate 31, and the two ends of the positioning cylinder 35 are hinged to the support frame plate 31 and the connecting rod 33, respectively.

[0051] Partial bearing roller 21 includes roller A 214 and roller B 215 arranged coaxially, and a tilting cylinder 34 is arranged between roller A 214 and roller B 215.

[0052] The transverse baffle 12 ensures that one end of the tilting cylinder 34 is mounted on it in a hinged manner and arranged between the carrier roller 21, which is divided into two sections of roller body A roller 214 and B roller 215, thus avoiding spatial movement interference between the tilting cylinder 34 and the carrier roller 21.

[0053] For the segmented bearing roller 21, the inner ends of its A roller 214 and B roller 215 are rotatably mounted to the support plate fixed to the transverse baffle 12. The outer ends of its A roller 214 and B roller 215 are each provided with two sets of transmission sprockets 211. The adjacent single-segment bearing roller 21 is also provided with transmission sprockets 211 at both ends, so as to ensure that the A roller 214 and B roller 215 can be powered by the adjacent bearing roller 21 through the corresponding chain 212.

[0054] The positioning cylinder 35 has two sets that operate synchronously, which are respectively arranged on both sides of the bearing roller 21 and are hinged to the connecting rod 33 on the corresponding side, thereby driving each set of connecting rods 33 and the indirectly connected positioning frame plate 32 to operate stably.

[0055] It should also be noted that an installation shaft 312 is rotatably connected at the connection between the support frame plate 31 and the baffle plate 311. The installation shaft 312 is rotatably installed between the two sets of side baffles 11 and arranged on the outside of the last support roller 21. When the tilting cylinder 34 drives the support frame plate 31 to tilt, the support frame plate 31 and the connecting rod 33 and the positioning frame plate 32 installed on it can rotate stably around the installation shaft 312 synchronously, and avoid spatial movement interference between the entire tilting assembly 3 and the support roller 21.

[0056] To ensure that the material feeding assembly 4 can be stably assembled on the mounting frame 1 and to effectively adjust the opening and closing gap so as to provide material feeding processing for the conveyed billets, the following technical solution is provided.

[0057] The feeding assembly 4 includes two sets of symmetrically arranged guide plates 41 and a guide roller 42 rotatably mounted to the inner end of the guide plate 41. The guide plate 41 is arranged on the bearing roller 21, and the outer end of the guide plate 41 is hinged to the inner wall of the side baffle 11. The two sets of guide plates 41 keep running in opposite directions synchronously.

[0058] During the synchronous reverse rotation of the two sets of guide plates 41, the gap between the two sets of side baffles 11 can be adjusted. When the billet that has not been transmitted along the center line of the mounting frame 1 runs to the guide plate 41, the billet will first contact one of the guide plates 41, and under the guidance of the guide plate 41 and the transmission action of the bearing roller 21, it will be adjusted towards the center line of the mounting frame 1, so that the billet can pass through the gap between the two sets of guide plates 41 stably. The guide roller 42 can act with the side wall of the billet that is passed through, thereby ensuring that the billet passes through the positive material assembly 4 stably.

[0059] When it is necessary to stop the billet from continuing to be transported downstream, the two sets of guide plates 41 are controlled to flip to a position perpendicular to the side baffle 11. At this time, the transport path of the billet can be effectively blocked to avoid the continuous transport of subsequent billets to the downstream end.

[0060] To ensure that the two sets of guide plates 41 always operate synchronously in opposite directions and to avoid interference with the bearing roller 21 and the conveyed blank, the following technical solution is provided.

[0061] The feeding assembly 4 also includes a guide shaft 43, a threaded rod 44, an adjusting motor 45, and a slide block 46. The guide shaft 43 and the threaded rod 44 are arranged in parallel and are rotatably mounted between two sets of side baffles 11. Two sets of slide blocks 46 are slidably mounted on the guide shaft 43. The geometric vertex of the bearing roller 21 is higher than the guide shaft 43 and the threaded rod 44. The threaded rod 44 is provided with two threaded grooves with opposite spiral directions. The threaded grooves at both ends are screwed into the two sets of slide blocks 46 respectively. The bottom of the guide plate 41 is provided with a strip-shaped guide groove 411. The slide block 46 is fixedly connected with a pin 461 that matches the corresponding strip-shaped guide groove 411. The adjusting motor 45 is fixedly mounted on the outside of the side baffle 11 and is coaxially fixedly connected to the threaded rod 44.

[0062] The guide shaft 43 ensures that the two sets of slides 46 always run in a straight line. A second support 14 is fixed to the outside of the side baffle 11 so that the adjusting motor 45 is stably assembled on the second support 14 and drives the threaded rod 44 to run stably. When the threaded rod 44 is running, the threaded grooves at both ends of it can drive the two sets of slides 46 to maintain the same speed and symmetrical movement. Then, through the cooperation of the pin shaft 461 and the strip guide groove 411, the two sets of guide plates 41 are driven to achieve synchronous reverse attitude adjustment.

[0063] Setting the guide shaft 43 and threaded rod 44 below the geometric apex of the bearing roller 21 can effectively prevent spatial motion interference between the billet and the guide shaft 43 or threaded rod 44 during the transmission process.
