[0051] The degradable tableware refers to the tableware which can cause biochemical reaction under the action of natural environment microorganisms (bacteria, mold, algae) and enzymes, causing appearance mold to internal quality change, and finally forming carbon dioxide and water. The use materials of the degradable tableware are divided into two kinds: one is made of natural materials, such as paper products, straw, starch, etc., which can be degraded and is also called environmental protection product; the other is made of plastic as the main component, adding starch, photosensitizer and other substances.

[0052] The production of the existing degradable tableware generally adopts semi-automatic equipment for production, and generally only one upper and lower cutting tool is used for cutting starch balls on the cutting structure of the material outlet, the pneumatic conveying pipe structure is single, and the cut starch balls are sent to the discharge end through the pneumatic conveying pipe structure. After the starch balls are sent to the upper side of the hot-pressing forming mold through the slide rail, the falling point position is uncertain, resulting in that the tableware after hot-pressing forming has too much material, causing waste. In addition, part of the finished products has the problem of uneven material, one side has too much material and the other side has too little material, resulting in low product qualification rate.

[0053] The utility model provides a kind of degradable tableware production equipment 100 for solving above problems.

[0054] Please refer to Figures 1 to 8 In the embodiment of the utility model, mainly in order to solve the traditional degradable tableware production equipment in the process of production, cutting good flour ball after entering mould, since its in mould drop point often not in the center position of mould, so after hot-press forming, the tableware finished product formed often there is uneven thickness, one side of finished product is thicker and one side is thinner, part finished product will also because one side forming material is too little, and the notch condition generated. In order to solve above problems, improve the qualified rate of finished product tableware, in the embodiment, the degradable tableware production equipment 100 is first improved on the stirring structure 2 of mixed storage structure, specifically, the discharge structure on the discharge end 221 of stirring structure 2 is redesigned, the traditional one discharge hole is set as multiple discharge round holes, specifically, the diameter of main discharge round hole is larger, for outputting larger starch ball, while multiple smaller diameter auxiliary discharge round holes are arranged on its periphery position, after starch material is fully stirred in stirring structure 2, it is simultaneously discharged through main discharge round hole and multiple auxiliary discharge round holes, at this time, cutting structure 3 is cut to the mixed material discharged from multiple round holes, and it is separated into starch ball material similar to spherical shape, including one relatively larger starch ball and multiple small starch balls, and the cut starch material is sent to hot-press forming structure 4 on conveying structure and is hot-press formed, in the process, multiple cut starch materials are transported simultaneously, in the process of transportation, due to rolling and other reasons, cut starch material gradually forms relatively standard circular structure, and is simultaneously conveyed to hot-press forming structure 4, when starch ball is sent to the mould of hot-press forming structure 4, one larger starch ball is main forming material, and it is located in the middle position of mould, and multiple relatively smaller starch balls are divided into the periphery of large starch ball, and can supplement the material around large starch ball, especially when forming bowl tableware, the forming area on mould is generally arc-shaped concave, if large starch ball does not fall to the middle position of mould forming area, multiple small starch balls can also roll to the side of mould forming groove with less starch ball content along the arc-shaped side wall of mould forming area, so that the problem of uneven thickness of product sidewall after forming or the problem of not closed slot caused by large starch ball not moving to position can be effectively avoided, and the yield of product can be effectively improved.

[0055] The conveying structure mainly includes two parts, the first is the pneumatic conveying structure 5 connected with the discharge end 221, which is a tubular structure, which can promote the formation of spherical starch blocks after cutting in the inner wall of the circular pipe during conveying by airflow and air pressure. One end corresponds to the tray conveying structure 6 on the horizontal plane, and the starch ball material is sent to the tray conveying structure 6 through the pneumatic conveying structure 5, and then conveyed to the hot pressing forming structure 4 for hot pressing forming.

[0056] The number of the auxiliary discharge round holes is four, and in the actual transportation process, one end of the support is connected with the discharge end 221, and the main conveying pipe 5121 inside the fixed support 511 is arranged corresponding to the main discharge round hole, and four auxiliary conveying pipes 5122 are arranged corresponding to the four auxiliary discharge round holes. After the cutting structure 3 cuts off the discharged starch material, the larger starch material falls into the main conveying pipe 5121, and the four smaller starch materials fall into the four auxiliary conveying pipes 5122. A plurality of starch materials are transported in a plurality of conveying pipes. In this embodiment, pneumatic conveying pipes are used, which are widely used in material transportation and will not be described here. Before the plurality of starch ball materials move to the end of the plurality of conveying pipes, the discharge position of the discharge end on the horizontal plane can be adjusted by the movable discharge structure 52 on the frame structure 1, so that the plurality of starch ball materials can be discharged on the tray conveying structure 6. In this embodiment, the plurality of conveying pipes are fixed by the fixed support 511, wherein the larger diameter conveying pipe is located in the hole part 5112 in the middle of the fixed support 511, and the four smaller diameter auxiliary conveying pipes 5122 are respectively fixed in the plurality of clamping parts 5113 on the circumferential position of the hole part 5112. By fixing the plurality of conveying pipes by the fixed support 511, the four auxiliary conveying pipes 5122 and the main conveying pipe 5121 form an integrated conveying structure, which realizes simultaneous discharge of the plurality of starch ball materials in the same group, and at the same time, the discharged plurality of starch ball materials are kept in the material transportation state of four small balls uniformly surrounding one large ball.

[0057] The tray conveying structure mainly comprises a supporting plate 61 and a driving structure 62, in order to increase the one-time forming quantity of tableware and improve the production efficiency, a plurality of supporting units 611 for supporting a plurality of groups of starch ball materials are arranged on the supporting plate 61, and in the process of material conveying, the position of the discharging end of the pneumatic conveying pipe structure 51 is adjusted through the movable discharging structure 52, so that a plurality of groups of starch ball materials can be continuously discharged into the plurality of supporting units 611 for placement, and in the actual operation process, in order to ensure the circular feature of the starch ball as much as possible, the distance between the end of the discharging end of the pneumatic conveying pipe structure 51 and the supporting plate 61 should not be too large, which can be set according to the actual situation, and in order to position the discharged plurality of starch ball materials and keep the position feature of four small starch balls surrounding one large starch ball, the supporting unit 611 is provided with a main supporting hole and four auxiliary supporting holes arranged around the main supporting hole, and when a plurality of starch ball materials in the same group are discharged, the position feature of four small starch balls surrounding one large starch ball can also be kept at the supporting element, and a supporting piece 612 is arranged on the lower end of each supporting unit 611 to block one end of the plurality of supporting holes, so that the plurality of starch balls can keep stable conveying effect on the supporting plate 61. When a group of starch ball materials is placed on each of the plurality of supporting units 611, the first motor 621 starts to work, and when the first screw rod 622 rotates, the lower end of the supporting plate 61 moves on the frame structure 1, and finally the supporting plate 61 moves to the forming position of the hot-press forming structure 4.

[0058] The supporting unit 611 is provided in plurality, and it is conceivable that the movable discharging structure 52 should have the adjusting effect of moving in the horizontal plane, specifically, the movable discharging structure 52 should have the movement effect in the X direction and the Y direction in the horizontal plane, so as to drive the discharging end of the plurality of conveying pipes to adjust the position in the horizontal plane. Therefore, many structures can be applied. For example, cylinder structures are arranged in the X direction and the Y direction at the same time, or corresponding screw rod structures are arranged in the X direction and the Y direction at the same time, which can realize the position adjustment of the discharging end of the plurality of conveying pipes in the horizontal plane. The above structures are common driving adjustment structures, which will not be described in detail here.

[0059] When the supporting plate 61 moves to the forming position of the hot-press forming structure 4, the output end of the cylinder 6122 is suddenly retracted, the shutter 6121 is quickly turned over under the action of the spring 6123, at this time, one end of the main receiving hole and the four auxiliary receiving holes is simultaneously opened, and the plurality of starch ball materials will fall into the forming area in the hot-press forming structure 4 for hot-press forming. After the discharging is finished, the output end of the cylinder 6122 is slowly extended, drives the shutter 6121 to overcome the elastic force of the spring 6123, and then is attached to one end surface of the supporting plate 61, thereby lifting the plurality of starch ball materials.

[0060] When the hot-press forming structure 4 works, the hydraulic system 42 drives the upper die 411 to move in a guided manner on the guide frame 12, a plurality of concave forming holes 4121 are arranged on the forming surface of the lower die 412, and a plurality of receiving units 611 are arranged corresponding to the plurality of forming holes 4121. When discharging, a plurality of groups of starch ball materials fall into the plurality of forming holes 4121 at the same time. As can be imagined, the vertical height between the supporting plate 61 and the lower die 412 should not be too large. When the plurality of starch ball materials in the same group fall into the forming hole 4121 at the same time, the larger starch ball is located at the middle position of the forming hole 4121, and the four smaller starch balls are arranged at the four surrounding positions. In the process of hot-pressing, the material at the position of the forming wall can be compensated. If the larger starch ball material is not located at the middle position of the forming hole 4121, the four smaller starch balls can roll on the arc-shaped inner wall of the forming hole 4121 to the side of the larger starch ball material for compensation, thereby avoiding the situation that the product side wall is not uniform in thickness after forming. When the mold is closed, the product shape is formed through the cooperation between the pressure head 4111 and the forming hole 4121, the heating plate on the upper die 411 can heat the material to accelerate the material setting, and at the same time, the upper die 411 and the lower die 412 are separated after forming, and the cooling plate can cool the product. Specifically, a base 43 is arranged below the lower die 412 on the frame structure 1, which plays a role in supporting the upper die 411, and the base 43 is provided with a pad 44 to buffer the impact force generated during the mold closing process. A guide sleeve 45 is further arranged on the guide shaft of the guide frame 12 to limit the movement of the upper die 411 and ensure the mold closing precision of the upper die 411 and the lower die 412. The heating plate and the cooling plate are integrated in the upper die 411 and the lower die 412, respectively.

[0061] The shell 22 is arranged above the conveying structure by the support frame 11, the second motor 23 works and drives the main shaft 211 to rotate through the transmission belt 231, so that the starch material in the shell 22 is stirred and mixed by the plurality of stirring rods 212, the inverted trapezoidal feed inlet 222 is arranged at the highest position of the arc-shaped peripheral wall of the shell 22, and the discharge end 221 is arranged at the lowest position of the arc-shaped peripheral wall of the shell 22. In the actual processing process, in order to ensure the efficiency of discharging, the feed inlet 222 can be sealed by a cover plate, and then the shell 22 is filled to facilitate discharging.

[0062] The cutting structure 3 is driven by the third motor 31, and in the working process, the mixed starch material is discharged from the shell 22 through the main discharge circular hole and the four auxiliary discharge circular holes. At this time, the third motor 31 drives the cutter 32 to rotate, so as to cut the starch material. In this process, the size of the starch ball material for hot pressing can be controlled by the rotating speed of the third motor 31. It is conceivable that the faster the rotating speed of the motor, the less the cut starch material, and the slower the rotating speed, the more the cut starch material.

[0063] In addition, the fixed support 511 is provided with a avoiding groove for avoiding the rotating cutter 32, and a plurality of fixed rings 513 are arranged on the fixed support 511 corresponding to the outer sides of the plurality of auxiliary conveying pipes 5122, so as to enhance the fixed installation effect of the plurality of auxiliary conveying pipes 5122.

[0064] The finished product detection system and the control device are further arranged on the frame structure 1, wherein the control device is installed in the base 43, the finished product detection system detects the tableware after hot pressing, the control device is arranged on the frame structure 1 and connected to the finished product detection system and the third motor 31, and is used for adjusting the rotating speed of the third motor 31 through the detection result of the finished product detection system.

[0065] Specifically, the finished product detection system comprises a material taking structure 7 and a visual analysis element 8. The material taking structure 7 comprises a moving structure composed of a support structure 71, a transmission belt and a lead screw structure. The support structure 71 comprises a roller, a guide rail and a support frame 11, which are used to convey the belt body 72 and ensure its normal operation. The inside contains a belt driving system, usually a motor drive, equipped with a speed reducer, a transmission belt or chain, providing smooth movement and a speed controller to adjust the speed of the conveyor belt to match the rhythm of detection and handling. The belt body 72 is made of rubber, plastic or metal mesh and runs along the roller or slide rail. The lead screw structure comprises a vertical lead screw 731 and a horizontal lead screw 73. The vertical lead screw is used to adjust the height of the camera bracket and the suction cup bracket 77. The horizontal lead screw 73 is sleeved on the slide rail and is used to control the movement of the suction cup bracket 77. The whole is also taken by negative pressure suction. Specifically, it is connected to the compressed air system through the connecting pipeline 75 to control the action of the pneumatic cylinder. The action frequency and position of the pneumatic cylinder are controlled by the electromagnetic valve and pneumatic control valve in the pneumatic cylinder control system 76 to drive the suction cup 781 or clamp to move up and down. Usually, it is a double-acting cylinder that provides telescopic movement. The suction cup bracket 77 is used to support the suction cup 781 device and the camera. The suction cup device guide rail 78 is used to constrain the movement direction of the pneumatic cylinder to ensure its smooth linear motion. The suction cup 781 or clamp is connected to the end of the pneumatic valve, which is specially designed to grab cutlery. The suction cup bracket drive device 782 inside is a driving motor and transmission device that drives and controls the movement position of the horizontal lead screw 73 to position the tray bracket. The horizontal lead screw guide seat 79 is used to constrain the movement direction of the horizontal lead screw 73 to ensure its smooth linear motion.

[0066] In the actual material taking process, the plurality of products molded in the lower mold 412 are taken out and placed on the conveyor belt body 72 for discharging. The molding effect of the plurality of products after molding is obtained by the visual analysis element 8 during this process. Specifically, the top camera 81 adopts an OPEN MV vision module with high-definition shooting and image processing capabilities and is connected to an image analysis system. The lighting system is usually used in cooperation with the camera to provide uniform lighting conditions to improve detection accuracy. The bottom camera 82 adopts an OPEN MV vision module with high-definition shooting and image processing capabilities and is connected to an image analysis system. The two cameras work together to detect product defects using machine vision and edge detection technology. By combining the YOLOv5 deep neural network model and the DeepSORT algorithm, efficient defect detection is realized. In order to avoid tracking loss caused by target occlusion, the DeepSORT algorithm is optimized. The edge detection technology further accurately identifies product defects and feeds back the detection results and deviation information to the embedded single-chip microcomputer. The embedded single-chip microcomputer performs algorithm operation and adjusts the speed of the third motor 31 through PID closed-loop control, thereby realizing real-time detection and control of product defects.

[0067] When the product is on the conveyor belt body 72, the OPENMV vision processing module is triggered, and the camera takes a short video of the finished product on the conveyor belt. The embedded microcontroller will select several frames of images for image optimization.

[0068] Image optimization includes two algorithms: grayscale and filtering. The grayscale processing uses the weighted average method to improve the filtering effect and reduce the system data operation amount, thereby improving the overall operation efficiency. Filtering is used to reduce Gaussian noise in the image and improve the accuracy of subsequent image recognition.

[0069] The recognition area segmentation mainly uses the OSTU foreground segmentation algorithm to segment the region of interest in the image. This method divides the "foreground" (products and defects to be identified) and "background" (conveyor belt and other irrelevant parts) in the image, further improves the recognition accuracy, and more accurately judges the product defects.

[0070] Defect detection uses the YOLOv5 deep neural network model combined with the DeepSORT algorithm to achieve efficient model defect detection and avoid target loss, ensuring the accuracy of defect recognition.

[0071] The detected finished product image is compared with the finished product image through image processing, edge detection, and image completion techniques to determine the degree and location of the defect. Then it communicates with the embedded microcontroller, and the algorithm controls the speed of the corresponding third motor 31.
