Description

Technical Field

[0001] This invention relates to the field of edge trimming machine technology, specifically to a plate edge trimming machine with a thickness compensation mechanism and its usage method. Background Technology

[0002] The plate trimming machine is an automated equipment specifically designed for the tableware production process. It is mainly used for edge trimming and edge processing of the formed plate blanks. It can accurately remove excess scraps from the blanks, making the plate edges uniform in size, neat and smooth. At the same time, it can adapt to the processing needs of plates of different specifications and materials, greatly improving the standardization and production efficiency of plate production. The plate trimming machine compensates for thickness when cutting the edge scraps of plates. Its core purpose is to counteract the uneven thickness of the plate blanks generated during the forming and drying processes. It adapts to the wear and tear of the cutter over long-term use and minor installation deviations, and addresses the thermal deformation caused by friction between the cutter and the blank during the cutting process. At the same time, it matches the different cutting depth requirements of plate blanks made of different materials, ensuring that the cutter's cutting depth is accurate and stable. This avoids problems such as cutting too shallow and leaving burrs, or cutting too deep and damaging the plate surface. Ultimately, it ensures that all plates have uniform edge dimensions and smooth, neat edges, improving the production qualification rate and standardization. The plate trimming machine with a thickness compensation mechanism achieves precise compensation through a closed-loop system of "sensor detection, algorithm calculation, and execution adjustment". First, non-contact sensors collect the actual thickness data of the plate in real time, and simultaneously capture the thickness deviation caused by batch differences, temperature fluctuations in the processing environment, and changes in the amount of waste cut. Then, the control system compares the measured data with the preset standard thickness, calculates through PID self-tuning or fuzzy control algorithms, and outputs compensation commands. Finally, the stepper motor drives the eccentric shaft, multi-link and other actuators to precisely adjust the lateral clearance and overlap of the cutter, or finely adjust the vertical distance between the cutter and the plate, to ensure that the cutter always fits the actual thickness of the plate to form the optimal cutting state, completely offsetting the processing error caused by uneven thickness, and ensuring the flatness and consistency of the cut edges of each plate. In the automated loading and unloading process after trimming disposable foam plates, existing technologies generally adopt a suction cup operation mode. Although this mode can achieve automated operation of the loading and unloading process, it is limited by the soft texture and weak surface pressure resistance of foam material. During the suction and release operation, the soft material of the suction cup will deform and shift its position, which will cause slight friction with the plate surface, resulting in scratches on the plate surface and directly damaging the appearance and molding precision of the product. Therefore, to address the above problems, a plate trimming machine with a thickness compensation mechanism and its usage method are proposed. Summary of the Invention

[0013] A method for using a plate trimming machine with a thickness compensation mechanism; Step 1: When loading the plates, the bowls of the arrayed plates face upwards. The conveyor belt moves the plates to the front end of the transmission support assembly. The servo motor drives the transmission column to rotate inside the machine base. After the cutting assembly rotates 180 degrees, multiple membrane shells are in contact with the plates. Multiple fans are started, and the fans deliver external air into the inside of the cylinder. Multiple solenoid valves are open, and the air enters the thin tube, tapered tube, solenoid valve and extension tube through the cylinder, and then enters the conversion shell and flows out from the first air hole at the front end. The inside of the cutting assembly is connected to the inside of the built-in tube through the central groove and the lower passage. A negative pressure is formed inside the cutting assembly. The negative pressure hole generates an adsorption force on the plates with the membrane shells in contact. The servo motor resets the cutting assembly until the support arm is in contact with the top of the support block. The linear drive mechanism controls the cutting blade to move downwards. Step 2: When cleaning the chips, start the electric cylinder. The electric cylinder drives the folded shell to move to the right. The folded shell slides inside the conversion shell. The piston rod of the electric cylinder moves inside the movable hole. The sealing ring inside the movable hole prevents gas leakage until the right side of the folded shell is in contact with the right side inside the conversion shell. The third air hole is staggered with the first air hole, and the fourth air hole is aligned with the second air hole. The first air hole is blocked. External air will enter the fourth air hole and the second air hole through the first air hole at the rear end, and be blown out through the fourth air hole. The fourth air hole is located at the upper end of the support plate. The chips falling from the upper end of the support plate are blown away. Step 3: When feeding the processed plates, the transmission support assembly, cutting seat assembly, negative pressure generating assembly and air duct switching assembly are rotated 180 degrees by the servo motor to reduce the fan speed. The solenoid valve is closed, and the fan delivers air into the cylinder. The air enters the concentrating tank through the thin tube, cone tube and built-in tube, then enters the membrane shell through the air channel, and is blown out through the negative pressure hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting a transmission support component, the device abandons the traditional suction cup loading and unloading method and innovatively adopts a negative pressure adsorption positioning plate design, which effectively avoids the core problem that traditional suction cups are prone to deformation and positional shift during adsorption and release due to their soft material, which in turn causes friction with the surface of soft materials such as foam plates, and greatly reduces the probability of scratches and appearance damage on the surface of the plate. 2. In this invention, the air duct switching component can quickly and efficiently remove the chips generated during the cutting process, avoiding chip accumulation that could affect subsequent processing steps or cause secondary damage to the plates. After being guided, the chips fall precisely to the designated collection area, simplifying the chip collection process and reducing manual cleaning costs. During the cleaning process, the structural design prevents the wind from affecting the plates in the adsorption state, ensuring the stability of the plates' adsorption and ensuring that the plates are accurately positioned after cutting, without affecting subsequent processing or unloading processes. 3. In this invention, the solenoid valve is used to achieve smooth separation of the plate and the adsorption component through forward air blowing, which completely solves the problem of poor detachment caused by the plate being tightly attached to the adsorption component during traditional feeding. This ensures a smooth and efficient feeding process, improves overall production efficiency, and the separation process is gentle and will not cause impact or damage to the surface of the plate, further maintaining the appearance quality of the plate. The stability of feeding also supports the continuity of subsequent batch processing and helps to achieve smooth operation of automated production. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] Please see Figures 1-9 The present invention provides a technical solution: A plate trimming machine with a thickness compensation mechanism and its usage method include a linear drive mechanism 1, a cutting blade 2, and an angle control component 3. A transmission support component 4 is installed on the upper end of the angle control component 3. A cutting seat component 5 is fixedly connected to the top of the transmission support component 4. A negative pressure generating component 6 is fixedly connected to the bottom of the transmission support component 4. An air duct switching component 7 is fixedly connected to the transmission support component 4 near its front end. The transmission support component 4 includes a support arm 41. A support plate 43 is fixedly connected to one side of the support arm 41. A concentrating groove 44 and a lower opening 46 are opened on the inner side of the support plate 43. A partition 45 is fixedly connected to the inner side of the concentrating groove 44. The negative pressure generating component 6 includes a cylindrical tube 61. A fan 62 is fixedly connected to the rear end of the cylindrical tube 61. A thin tube 63, a tapered tube 64, a solenoid valve 66, and an extension tube 67 are fixedly connected to the front end of the cylindrical tube 61 in sequence. An internal tube 65 is fixedly connected to the inner side of the tapered tube 64 near its upper end.

[0020] As a further implementation of this solution, a cutting blade 2 is fixedly connected to the front end of the linear drive mechanism 1. The cutting blade 2 is aligned vertically with the cutting seat assembly 5. An angle control assembly 3 is fixedly connected to the bottom end of the linear drive mechanism 1. Through the above settings, the fixed connection between the linear drive mechanism 1 and the cutting blade 2 ensures the installation stability of the cutting component and avoids the cutting blade 2 from shaking or shifting during the cutting process. The vertical alignment design between the cutting blade 2 and the cutting seat assembly 5 ensures that the cutting blade can accurately act on the edge of the plate that is adsorbed and positioned during the cutting process, providing a structural basis for the cutting accuracy. The fixed support of the angle control assembly 3 on the linear drive mechanism 1 can disperse the impact force generated during the cutting process, reduce the deformation of the linear drive mechanism 1, and further ensure the stability of the cutting depth. With the thickness compensation system, the cutting quality can be controlled more accurately, reducing the risk of cutting too shallowly and leaving burrs or cutting too deeply and damaging the plate surface. As a further implementation of this solution, the angle control component 3 includes a base plate 31. A support block 32 and a base 33 are fixedly connected to the top of the base plate 31. A drainage groove 35 is provided on the inner side of the base plate 31. The left side of the base 33 is fixedly connected to the housing of the servo motor 34. The top of the base plate 31 is fixedly connected to the linear drive mechanism 1. The upper end of the support block 32 supports the support arm 41. Through the above arrangement, the base plate 31 serves as the main frame of the angle control component 3, providing a stable installation foundation for the support block 32, the base 33, and the linear drive mechanism 1, ensuring assembly stability. Precision: The support block 32 bears the weight of the support arm 41, which can prevent the support arm 41 from sinking or shifting due to uneven force after it drives the transmission support assembly 4, the cutting seat assembly 5 and other components to rotate and adsorb the plate. This ensures that the plate adsorbed on the cutting seat assembly 5 can always maintain a precise relative position with the cutting blade 2, thus ensuring cutting precision. The drain groove 35 opened on the inner side of the base plate 31 provides a precise drop channel for the chips. With the chip cleaning mechanism, the chips can fall quickly to the designated collection area, avoiding chip accumulation that affects subsequent processing or causes secondary damage to the plate. As a further implementation of this solution, a transmission column 42 is fixedly connected to the front end of the support arm 41. The transmission column 42 is rotatably connected to the inside of the base 33. One side of the transmission column 42 is fixedly connected to the main shaft of the servo motor 34. Through the above settings, the fixed connection between the transmission column 42 and the main shaft of the servo motor 34 and the rotatable connection inside the base 33 form a stable transmission structure, ensuring that the servo motor 34 can accurately drive the support arm 41 to rotate, thereby driving the transmission support assembly 4, the cutting seat assembly 5 and other components to complete the flipping and positioning action. The stability of the transmission structure can prevent the cutting seat assembly 5 from shaking during the flipping process, ensuring the accurate position of the plate adsorbed on the cutting seat assembly 5, preventing the subsequent cutting position deviation due to the flipping offset. The precise rotation control can make the flipping angle of the cutting seat assembly 5 accurate, such as after flipping 180 degrees, the membrane shell 55 is precisely attached to the plate, providing a guarantee for the reliability of negative pressure adsorption positioning and improving the consistency of feeding and positioning. As a further implementation of this solution, the central groove 44 is connected to the lower opening 46, and the bottom end of the support arm 41 near the lower opening 46 is fixedly connected to the top end of the built-in tube 65. The lower opening 46 is connected to the inside of the built-in tube 65. Through the above settings, the connection design between the central groove 44 and the lower opening 46, together with the connection between the lower opening 46 and the inside of the built-in tube 65 and the fixed connection between the support arm 41 and the built-in tube 65, constructs a stable negative pressure transmission channel, ensuring that the negative pressure generated inside the built-in tube 65 can be smoothly transmitted to the inside of the cutting seat assembly 5, providing a reliable negative pressure basis for the adsorption and positioning of the cutting seat assembly 5 on the plate. As a further implementation of this solution, the cutting seat assembly 5 includes a lower base 51, with an extension cylinder 52 and an upper base 53 sequentially fixedly connected to the top of the lower base 51. Air channels 54 are provided on the inner sides of the lower base 51, extension cylinder 52, and upper base 53. A membrane shell 55 is fixedly connected to the outer side of the upper base 53. A negative pressure hole 56 is provided at the upper end of the membrane shell 55. The air channels 54 communicate with the inner side of the membrane shell 55. Through the above arrangement, the sequential fixed connection of the lower base 51, extension cylinder 52, and upper base 53 forms a... The main structure of the sturdy cutting seat assembly 5 provides reliable installation support for the membrane shell 55. At the same time, this support ensures that the adsorption stability of the plate is not affected when removing chips. The air channel 54 opened on the inner side of the lower base 51, extension cylinder 52, and upper base 53 is connected to the inner side of the membrane shell 55 to form a gas transmission channel. This ensures that the adsorption force can be accurately applied to the plate through the negative pressure hole 56 during negative pressure adsorption, and also provides a smooth gas path for forward blowing separation during feeding. As a further implementation of this solution, the bottom end of the lower base 51 is fixedly connected to the top end of the support plate 43. The support plate 43 has an opening near the air channel 54. The air channel 54 is connected to the collection tank 44 through the opening. Through the above settings, the fixed connection between the lower base 51 and the support plate 43 and the air channel 54 connected to the collection tank 44 through the opening further improve the channel for negative pressure transmission and gas delivery, ensuring that negative pressure or positive air blowing can be smoothly transmitted to the membrane shell 55, improving the reliability of adsorption and separation actions, ensuring accurate feeding positioning and smooth feeding, and reducing the impact or damage to the plate caused by unstable airflow. As a further implementation of this solution, the duct switching assembly 7 includes a conversion shell 71. The conversion shell 71 has a first air hole 72 at its front and rear ends, a second air hole 73 at its rear end, and a movable hole 74 at its right end. A sealing ring is fixedly connected to the inner side of the movable hole 74, and the inner side of the movable hole 74 is fitted to the outer side of the piston rod of the electric cylinder 75 through the sealing ring. A folded shell 76 is fixedly connected to the end of the piston rod of the electric cylinder 75. A third air hole 77 is opened at the front end of the folded shell 76, and a fourth air hole 78 is opened at the rear end. The inner side of the folded shell 76 is fitted to the inner side of the conversion shell 71. The third air hole 77 is aligned with the first air hole 72, and the fourth air hole 78 is staggered with the second air hole 73. Through the above arrangement, the conversion shell 71 serves as the main frame of the duct switching assembly 7, providing a stable installation foundation for each component. The sealing ring inside the moving hole 74 ensures sealing performance and prevents gas leakage. It ensures that the airflow switching can be precisely controlled when the electric cylinder 75 drives the folded shell 76 to move. The fitting design of the folded shell 76 and the inner side of the conversion shell 71, as well as the opening of the third air hole 77 and the fourth air hole 78, realize the precise switching of the airflow channel. During the adsorption stage, the third air hole 77 is aligned with the first air hole 72, and the fourth air hole 78 is staggered with the second air hole 73, ensuring the airflow path required for the formation of negative pressure and preventing wind from affecting the adsorption of the plate. During the chip cleaning stage, the third air hole 77 is staggered with the first air hole 72, and the fourth air hole 78 is aligned with the second air hole 73, so that the airflow can be precisely blown out from the fourth air hole 78, efficiently cleaning the chips. The precise airflow switching function not only improves the chip cleaning efficiency, but also ensures the stability of the plate adsorption and prevents the plate position from shifting during the cleaning process. As a further implementation of this solution, the outer side of the conversion shell 71 is fixedly connected to the support arm 41, the cylinder body of the electric cylinder 75 is fixedly connected to the right side of the support arm 41, and the position of the conversion shell 71 near the rear end first air hole 72 is fixedly connected to the front end of the extension tube 67. Through the above settings, the fixed connection between the conversion shell 71 and the support arm 41 and the fixed connection between the cylinder body of the electric cylinder 75 and the support arm 41 enable the air duct switching component 7 to rotate synchronously with the support arm 41, ensuring that the air duct switching component 7 is always in a precise chip cleaning position during the flipping and positioning of the cutting seat component 5, thus ensuring the cleaning effect. The fixed connection between the conversion shell 71 and the extension tube 67 ensures the stability of the airflow delivery channel, allowing external gas to smoothly enter the interior of the conversion shell 71, providing reliable airflow support for negative pressure formation and chip cleaning. The fixed connection between each component and the support arm 41 improves the overall structural coordination, reduces component interference during movement, ensures the smooth operation of the device, and improves overall production efficiency.

[0021] Workflow: When loading the plates, the plates in the array are positioned with their rims facing upwards and moved to the front end of the transmission support assembly 4 via the existing conveyor belt. The servo motor 34 is activated, driving the transmission column 42 to rotate. The transmission column 42 rotates inside the base 33. The support arm 41 rotates, causing the transmission support assembly 4, the cutting seat assembly 5, the negative pressure generating assembly 6, and the air duct switching assembly 7 to rotate simultaneously. When the cutting seat assembly 5 rotates 180 degrees, multiple membrane shells 55 are in contact with the plates. At this point, multiple fans 62 are activated, delivering external air into the cylinder 61. Multiple solenoid valves 66 are open, allowing air to flow through the cylinder 61 into the thin tube 63, the tapered tube 64, the solenoid valves 66, and the extension tube 67. The air then flows out from the first air hole 72 at the front end of the conversion shell 71. During this process, because the internal tube 65 is located at the front end of the narrow opening of the thin tube 63, according to Bernoulli's principle, the gas velocity is relatively high after flowing out through the narrow opening of the thin tube 63. However, the internal pressure of the built-in tube 65 is relatively small. At this time, a negative pressure is generated inside the built-in tube 65. Since the inside of the cutting seat assembly 5 is connected to the inside of the built-in tube 65 through the central groove 44 and the lower through port 46, a negative pressure is formed inside the cutting seat assembly 5. The negative pressure hole 56 generates an adsorption force on the plate that is attached to the membrane shell 55, thereby achieving the positioning effect between the plate and the membrane shell 55. The servo motor 34 resets the cutting seat assembly 5 until the support arm 41 is attached to the top of the support block 32. The support block 32 supports the support arm 41. The linear drive mechanism 1 controls the cutting blade 2 to move downward to cut the plate. Then, the depth of the downward movement of the cutting blade 2 is controlled by the actual thickness data of the existing laser sensor, thereby achieving the cutting edge effect of thickness compensation. The device changes the traditional working method of loading and unloading plates by suction cups. The suction cups are formed by negative pressure, which can significantly reduce the phenomenon of scratches on the surface of the plate caused by deformation, and improve the appearance and forming accuracy of the plate. During chip removal, the electric cylinder 75 is activated, causing the folded shell 76 to move to the right. The folded shell 76 slides inside the conversion shell 71. During this process, the piston rod of the electric cylinder 75 moves inside the movable hole 74. The sealing ring inside the movable hole 74 prevents gas leakage until the right side of the folded shell 76 is in contact with the right side inside the conversion shell 71. The third air hole 77 intersects with the first air hole 72, while the fourth air hole 78 aligns with the second air hole 73. In this way, the first air hole 72 is blocked, and external air will enter the fourth air hole 78 and the second air hole 73 through the first air hole 72 at the rear end. Inside 3, the chips are blown out through the fourth air hole 78, which is located at the upper end of the support plate 43. This allows the wind to blow away the chips that fall from the upper end of the support plate 43. After the chips collide with the front end of the linear drive mechanism 1, they will fall into the designated area through the discharge groove 35 for easy collection. During this process, the lower base 51, the extension tube 52 and the upper base 53 support the membrane shell 55, so the wind blown out from the fourth air hole 78 will not affect the upper end of the plate of the membrane shell 55, ensuring the stability of the plate adsorption. After the chips are cleaned, the folded shell 76 is reset. When unloading the processed plates, the servo motor 34 controls the transmission support assembly 4, cutting seat assembly 5, negative pressure generating assembly 6, and air duct switching assembly 7 to rotate 180 degrees as a whole. At this time, the wind speed of the blower 62 is reduced and the solenoid valve 66 is closed. The blower 62 delivers air into the cylinder 61, and the air enters the concentrating groove 44 through the thin tube 63, the cone tube 64, and the internal tube 65. Then, it enters the membrane shell 55 through the air channel 54 and is blown out through the negative pressure hole 56. The pressure of the gas separates the plates from the membrane shell 55, preventing some plates from falling off due to the plates being tightly attached to the membrane shell 55 during unloading. This ensures the effectiveness of unloading and facilitates further processing.
