Description

Technical Field

[0001] The present invention belongs to the technical field of wooden lunch box production, and particularly relates to a wooden lunch box production device and a production method thereof. Background Art

[0002] With the enhancement and implementation of environmental protection awareness, wooden lunch boxes, with their natural environmental protection and biodegradable characteristics, have become an ideal choice to replace traditional plastic lunch boxes and are increasingly widely used in the food packaging field. Their raw materials are taken from renewable wood and can decompose naturally after being discarded, without causing long-term pollution to the environment, meeting the current concept of green development, and the market demand continues to climb.

[0003] However, there are significant technical bottlenecks in the current wooden lunch box production equipment. Specifically, in terms of the forming accuracy of lunch boxes, traditional production devices are difficult to ensure the precise connection of each link. During the entire conveying process of the original board, there is a lack of effective limiting and anti-warping structures, and it is easy to deviate or warp. For example, ordinary conveyor belts cannot stably restrain the wooden original board, and the original board may deviate during transportation, resulting in deviation of the subsequent glue dispensing position, uneven glue distribution, and affecting the bonding strength between lunch box components. Secondly, when entering the folding and shaping link, it is difficult to accurately fold the edges and corners of the warped or deviated original board, resulting in large dimensional errors in the finished lunch box and irregular box body shapes, unable to meet the requirements of high-quality and standardized production. In addition, in terms of ensuring production continuity, the existing bin components have a single function, mostly using a simple stacking design, without the functions of automatic caching, cleaning, and precise alignment of the original board. The original board is prone to jamming and stacking chaos in the bin, and there is no precise alignment cylinder to calibrate the position of the original board, resulting in frequent interruption of the original board supply, seriously affecting the smoothness of the production process, increasing the equipment downtime for debugging, and significantly reducing the production efficiency and product qualification rate of wooden lunch boxes.

[0029] A production method of a wooden lunch box production device includes the following operation steps:

[0030] S01: Original board placement and conveying:

[0031] Stack the wooden original boards neatly on the original board placing table. Adjust the position of the clamping plate member through the adjusting bolts. Use the material clamping wheel to limit and fix the edge of the original board. The feeding cylinder drives the feeding driving member to drive the feeding shaft to rotate, so that the suction head on the feeding arm sucks the lowest - layer original board on the original board placing table and places it on the conveyor belt. The conveying motor starts, and drives the conveying shaft to rotate through the conveying grooved wheel, the conveying driving belt and the driven grooved wheel, so that the conveyor belt operates to convey the original board. During the conveying process, the pressing edge cylinder first drives the pressing edge extension arm to make the pressing edge strip act on the edge of the original board. Secondly, after further conveying, the gap between the pressing plate strip and the conveying main body clamps the original board. The extension anti - warping arm presses on the original board through the action of the torsion spring to prevent the original board from warping and ensure the smooth conveying of the original board;

[0032] S02: Glue application and spreading:

[0033] The original plate moves with the conveyor belt to above the dispensing table. The dispensing cylinder pushes the dispensing plate to slide, and the positions of the dispensing arm and the glue head support arm are adjusted through the kidney-shaped holes, so that the dispensing head is aligned with the position on the original plate where glue needs to be dispensed, and the dispensing operation is carried out. After the dispensing is completed, the original plate continues to move to above the smoothing table. The smoothing cylinder drives the smoothing plate to move along the guide posts, and the positions of the smoothing arm and the smoothing head are adjusted through the kidney-shaped holes to smooth the dispensed glue so that the glue is evenly distributed on the original plate;

[0034] S03: Feeding and alignment of the magazine:

[0035] The first return cylinder extends, driving the first return arm to push the smoothed original plate into the first group of the magazine mechanisms. The magazine drive motor drives the turnover box to rotate. Through the magazine drive shaft and the magazine drive bevel gears, the magazine driven bevel gear rotates, thereby driving the magazine drive gear disc and the magazine drive chain to operate. The original plate support plate moves with the chain to convey the original plate in the magazine frame upward. During this process, the gooseneck blows out air to dehumidify the original plate on the original plate support plate. When the original plate is conveyed to the middle of the magazine frame, the alignment cylinder extends to calibrate the position of the original plate. When the original plate enters the second group of magazine mechanisms, the original plate will flip back to the side with the glue facing up. The second return cylinder extends, driving the second return arm to push the original plate to the second group of the calibrated original plate and push it into the magazine mechanism;

[0036] S04: Auxiliary pressing:

[0037] After the original plate reaches the auxiliary pressing table, the auxiliary pressing cylinder drives the auxiliary pressing bar to move downward, cooperating with the pressing bar of the conveying component to press the original plate, facilitating the subsequent grasping operation;

[0038] S05: Grasping and transferring the original plate

[0039] The original plate transition motor starts, driving the original plate transition pulley to rotate through the original plate drive sheave, the original plate drive belt, and the original plate driven sheave, so that the original plate transition belt operates. The original plate transition lifting cylinder contracts to lower the original plate transition lifting plate to align with the original plate conveyed by the main frame. The grasping adjustment cylinder drives the grasping adjustment arm to slide through the grasping guide slider to adjust the distance between the two groups of grasping heads. After aligning with the center of the original plate, the grasping heads clamp the original plate, and then the original plate transition lifting cylinder is started to lift the grasped original plate. The original plate transition belt operates to transfer the grasped original plate to the folding and shaping component of the sub-frame;

[0040] S06: Folding and shaping:

[0041] The synchronization cylinder of the alignment table mechanism drives the synchronization disk to rotate. Through the synchronization groove and the synchronization shaft, the alignment plate is driven to move along the alignment track to align and position the original plate. The original plate is transferred to the folding table above the shaping bottom plate. The bottom support member supports the bottom of the original plate. The hemming cylinder drives the hemming arm to slide through the hemming slider, so that the hemming head folds the edge of the original plate. The corner folding cylinder drives the corner folding slider to slide along the corner folding track, and the corner folding member performs corner folding on the four corners of the original plate. The stamping cylinder drives the stamping plate to move downward along the second stamping column to stamp and shape the folded original plate to form a preliminary shape of the wooden lunch box. The return spring resets the finished product table after stamping is completed;

[0042] S07: Finished product placement and anti-detachment:

[0043] The finished product adjustment cylinder drives the finished product adjustment slider to move along the finished product adjustment track. Through the fixed plate, the position of the finished product placement table is adjusted to receive the folded and shaped lunch box. The finished product suction head sucks the shaped lunch box and places it on the finished product placement table. The overlapping plate at the end of the anti-detachment support arm rotates above the finished product placement table to limit the edge of the uppermost lunch box to prevent the lunch box from falling off during the sequential placement process, completing the safe placement of the finished product.

[0044] Beneficial effects: The present invention is reasonably designed, with a simple and stable structure and strong practicability. It also has the following beneficial effects:

[0045] 1. In terms of precise conveying: The conveying component cooperates with the first anti-warping mechanism through the conveyor belt with partition protrusions, effectively restricting the offset and warping of the original plate, ensuring the stability of the original plate during conveying, providing a precise processing basis for subsequent processes, and significantly improving the forming accuracy of the lunch box;

[0046] 2. In terms of efficient feeding: The inclined original plate placement table in the original plate placement component is combined with the card plate member, the suction head and the edge pressing mechanism to achieve the orderly storage, precise grasping and stable positioning of the original plate, improving the feeding efficiency and accuracy;

[0047] 3. In terms of high-quality glue application: The glue application component consists of a glue application mechanism and a spreading mechanism, which can flexibly adjust the glue application position and the amount of glue, and can evenly spread the glue, ensuring firm adhesion and good sealing of the lunch box components and improving the product quality;

[0048] 4. In terms of stable feeding: The dual-bin mechanism, the snake-neck tube dehumidification and the alignment cylinder design of the bin component realize the automatic caching, surface dehumidification and precise alignment of the original plate, effectively avoiding the jamming and confusion of the original plate, and ensuring the continuous and stable operation of the production process;

[0049] 5. In terms of reliable transfer: The original board grasping component cooperates with the transition belt and the lifting mechanism and multiple groups of grasping mechanisms, and can stably grasp and accurately transfer the original board, reducing the error and damage risk during the transfer process;

[0050] 6. In terms of precise forming: The edge folding and corner folding mechanisms of the folding and shaping component cooperate with the stamping device, and combined with the precise positioning of the alignment table mechanism, the precise folding and shaping of the lunch box can be achieved, ensuring that the finished product has standard dimensions and regular shapes;

[0051] 7. In terms of safe storage: The adjustment track, finished product suction head and anti-detachment mechanism of the finished product placement component can not only flexibly adjust the placement position, but also firmly adsorb the finished product and prevent it from falling off, ensuring the safe stacking and efficient storage of the finished product.

[0082] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0083] Embodiment 1:

[0084] In combination with Figure 1A wooden lunch box production device as shown is composed of a main frame 1 and a sub-frame 2. The sub-frame 2 is precisely installed at one end of the main frame 1, and the two are placed vertically at 90°. This unique layout design not only makes full use of space but also makes the connection between components more compact and reasonable, effectively improving the fluency and efficiency of the overall production.

[0085] On the upper surface of the main frame 1, a conveying component 3 is installed in an orderly manner. It undertakes the key task of conveying wooden original boards. One end of the conveying component 3 is connected to an original board placing component 4. This component is the starting point of the wooden original board, responsible for properly storing the original board and accurately and orderly conveying it onto the conveying component 3. Next to one side of the original board placing component 4 is a dispensing component 5. The dispensing component 5 can precisely control the amount and position of glue application, providing a solid foundation for the subsequent assembly and bonding of the wooden original board. On the other side of the dispensing component 5 is arranged a bin component 6. As a material transfer station in the production process, it can temporarily store the processed original boards to ensure the continuous operation of the production process. An auxiliary pressing component 7 on one side of the bin component 6 facilitates the turnover and grasping of the subsequent original boards by applying appropriate pressure.

[0086] And at one end of the sub-frame 2 close to the main frame 1, an original board grasping component 8 is provided, which can accurately grasp the original board conveyed by the main frame 1 and precisely transfer it to a folding and shaping component 9. The folding and shaping component 9 is the shaping core of the entire device. Through a series of precise folding and stamping actions, the original board is shaped into a regular lunch box shape. On one side of the folding and shaping component 9, a finished product placing component 10 is provided, which can properly collect and neatly arrange the formed wooden lunch boxes for subsequent packaging and transportation.

[0087] In this embodiment, refer to Figures 2 - 4The shown conveying component 3 serves as the core transmission part of the wooden lunch box production device. This component is mounted on the upper surface of the main frame 1. Based on the conveying body 301, conveying platforms 302 are symmetrically installed on the main frame 1 at both ends of the conveying body 301, providing a stable support foundation for the entire conveying process. On each conveying platform 302, a conveying shaft 303 is flexibly rotatably arranged. On the conveying shaft 303, two sets of conveying grooved pulleys 304 are further rotatably assembled. A conveyor belt 305 is tensioned between the two sets of conveying grooved pulleys 304 located in the same vertical plane, forming a stable transmission channel. A number of partition protrusions 306 are evenly distributed on the surface of the conveyor belt 305. These protrusions can accurately partition and position the original board, ensuring that the original board does not shift during the conveying process and steadily moves along the predetermined path. In terms of power transmission, a driven grooved pulley 307 is firmly fixed on one of the conveying shafts 303. On the main frame 1 directly below the driven grooved pulley 307, a conveying motor 308 is installed as the power source of the entire conveying component. A conveying grooved pulley 309 is connected to the rotating shaft of the conveying motor 308. The conveying grooved pulley 309 and the driven grooved pulley 307 are cooperated through a conveying drive belt 3010. When the conveying motor 308 is started, through the transmission of the conveying drive belt 3010, the driven grooved pulley 307 is driven to rotate, and then the entire conveying shaft 303 and the conveyor belt 305 are driven to operate, realizing the continuous and stable conveying of the wooden original board;

[0088] In order to further ensure the flatness of the wooden original board during the conveying process, two sets of support arms 3011 are arranged on the conveying body 301. A first anti-warping mechanism 3012 is equipped on the support arms 3011. At the same time, a pressing strip 3013 is also arranged between the two sets of support arms 3011. The pressing strip 3013 is placed between the two sets of conveyor belts 305 and a certain gap is deliberately reserved between the pressing strip 3013 and the conveying body 301, which can not only play a role in pressing and restraining the original board but also will not hinder the normal conveying of the original board;

[0089] The design of the first anti-warping mechanism 3012 includes two sets of anti-warping bottom parts 30121 fixedly installed on the support arms 3011. An outward anti-warping arm 30122 is connected to the anti-warping bottom parts 30121 through a torsion spring. When the wooden original board enters the pressing strip 3013 during the conveying process, the outward anti-warping arm 30122 will automatically press down the original board under the action of the torsion spring. With the elastic buffer of the torsion spring, it can not only effectively inhibit the warping of the original board but also avoid damage to the original board caused by rigid extrusion, comprehensively ensuring the flatness and stability of the original board during the conveying process and laying a solid foundation for the accurate progress of subsequent processes.

[0090] In this embodiment, refer to Figure 5The original board placing component 4 shown serves as the feeding part of the production process of wooden lunch boxes, taking into account both storage flexibility and feeding accuracy. This component takes the inclined original board placing table 40 as the core carrier. On the surface of the original board placing table 401, several groups of clamping plate parts 403 are orderly installed through adjusting bolts 40. On the surfaces of these clamping plate parts 403, oblong holes 404 are opened. Users can flexibly adjust the spacing of the clamping plate parts 403 according to the actual size of the original board to ensure that original boards of different specifications can be stably stored. At one end of the clamping plate part 403 away from the oblong hole 404, a material clamping wheel 405 is provided, which can provide smooth rolling assistance during material taking and reduce the wear on the surface of the original board. On one side of the original board placing table 401, a feeding table 406 is provided. A feeding shaft 407 is rotatably arranged between the two feeding tables 406. A feeding arm 408 is fixed on the feeding shaft 407, and several groups of suction heads 409 are evenly distributed thereon. Using the principle of vacuum adsorption, it can accurately fit the surface of the original board and stably grab a single original board. In terms of power transmission, a feeding cylinder 4010 installed on the feeding table 406 drives a feeding driving part 4011 through a telescopic rod. The latter is tightly fixed to the feeding shaft 407. Through the reciprocating motion of the cylinder, the rotation and lifting of the feeding arm 408 are realized, so as to accurately transfer the original board to the conveying component 3. In addition, a through groove for giving the feeding arm 408 a swinging space is opened on the conveying main body 301. On the other side of the original board placing table 401, the edge pressing table 4012 undertakes the important responsibility of ensuring the stable subsequent input of the original board. The edge pressing cylinder 4013 serves as the power source and is rotationally connected to the edge pressing extension arm 4014 through a telescopic rod. When the original board is placed in the predetermined position, the edge pressing cylinder 4013 is quickly started, pushing the edge pressing extension arm 4014 to rotate around the hinge point, so that the edge pressing strip 4015 at the end smoothly presses down the edge of the original board to ensure that the original board is effectively conveyed under the pressing strip 3013.

[0091] In this embodiment, referring to Figure 6 The dispensing component 5 shown serves as the component for performing the bonding process during the production of wooden lunch boxes. It is jointly composed of a dispensing mechanism 501 and a spreading mechanism 502 with complementary functions to ensure that the glue is evenly and accurately applied to the designated position of the original board, providing a reliable guarantee for the forming quality of the lunch box.

[0092] The dispensing mechanism 501 uses the dispensing table 5011 as the basic bearing platform. A dispensing plate 5012 is slidably arranged thereon, and is stably slidably connected to the dispensing table 5011 through a linear slide rail. A dispensing cylinder 5013 is vertically installed on the dispensing table 5011, and its telescopic rod is firmly connected to the dispensing plate 5012, which can provide stable and precise linear driving force to achieve precise displacement of the dispensing plate 5012 in the horizontal direction. To meet the dispensing requirements of different specifications of lunch boxes, waist-shaped holes are ingeniously designed on the dispensing plate 5012. By adjusting and setting two groups of dispensing arms 5014, and on the dispensing arms 5014, glue head support arms 5015 are also arranged using waist-shaped holes. Dispensing heads 5016 are installed at the ends of each group of glue head support arms 5015. This multi-level and adjustable structural design enables the dispensing mechanism 501 to accurately control the dispensing position and meet diverse production requirements;

[0093] The spreading mechanism 502 includes a spreading table 5021, on which a spreading cylinder 5022 is vertically installed. The end of the telescopic rod of the spreading cylinder 5022 is fixedly connected to a spreading plate 5023. To ensure the smoothness and precision of the movement of the spreading plate 5023, guide columns 5024 that cooperate with the spreading plate 5023 are also arranged on the spreading table 5021. Waist-shaped holes are also provided at both ends of the spreading plate 5023 for adjusting the position of the spreading arms 5025, and the waist-shaped holes on the spreading arms 5025 further fine-tune the position of the spreading heads 5026. Through this fine adjustment mechanism, the spreading mechanism 502 can evenly push away the glue smeared by the dispensing heads 5016, eliminate the problems of glue accumulation or uneven distribution, and form a uniformly thick and firm bonding layer of glue on the surface of the original plate;

[0094] In addition, on one side of the upper surface of the spreading table 5021, a first material return cylinder 5027 is also arranged, and a first material return arm 5028 is connected to its telescopic rod, which facilitates the subsequent precise pushing of the original plate into the bin assembly 6 to ensure the continuous operation of the entire production process.

[0095] In this embodiment, refer to Figure 7 The shown bin assembly 6 includes a bin frame 601, in whose cavity two mutually cooperating bin mechanisms 602 are arranged to form a double-cycle buffer system. At the same time, it can also cooperate to make the glue-coated side of the original plate face upward. And on the bin frame 601 between the two bin mechanisms 602, an anti-warping part similar in structure to the first anti-warping mechanism 3012 is arranged. It is mainly installed by hanging, so no further description is made specifically. At the top of the bin frame 601 of each bin mechanism 602, a turnover box 603 is carried. The turnover box 603 is precisely matched with the two bin mechanisms 602 respectively, and a bin drive motor 604 installed thereon serves as the power source;

[0096] Each silo mechanism 602 includes a silo body 6021, two sets of silo drive gear discs 6022 are rotatably arranged at both ends of the silo body 6021, and a silo drive chain 6023 is tensioned between the two sets of silo drive gear discs 6022 located on the same vertical plane. Several sets of raw plate support plates 6024 are evenly distributed on the two sets of silo drive chains 6023 to form a stable material carrying and transmission path. In terms of transmission, the ends of the rotating shafts of the two sets of silo drive gear discs 6022 located above are provided with silo driven bevel gears 6023. 025, the silo drive bevel gear 6026 meshing with it, the silo drive bevel gear 6026 is fixed on the silo drive shaft 6027, and the silo drive shaft 6027 is connected to the output shaft of the turnover box 603. In this way, after the silo drive motor 604 is started, the power is transmitted through the turnover box 603 and the silo drive shaft 6027 through the bevel gear, driving the silo drive gear plate 6022 to rotate, and then driving the silo drive chain 6023 and the raw plate supporting plate 6024 to circulate, realizing the orderly caching and transportation of the raw plates;

[0097] Several snake-neck pipes 605 are evenly distributed on the silo frame 601. The air outlets of these snake-neck pipes 605 are precisely aligned with the original board support plate 6024. They can be flexibly adjusted in direction to continuously blow air to dry the original board surface during storage and transportation, preventing subsequent glue overflow and ensuring bonding stability.

[0098] A positioning cylinder 606 is provided in the middle of the silo frame 601, which closely cooperates with the first group of silo mechanisms 602. When the original plate is about to be transferred to the second silo mechanism 602, the positioning cylinder 606 is quickly extended, and the position of the original plate is calibrated through precise pushing. On one side of the positioning cylinder 606, the second return cylinder 607 and the second return arm 608 on its telescopic rod work together to ensure the stability of the placement of the original plate after entering the second silo mechanism 602.

[0099] In this embodiment, see Figure 8 The auxiliary pressing assembly 7 shown includes a load-bearing auxiliary pressing platform 701, on which an auxiliary pressing cylinder 702 is vertically installed. The telescopic rod end of the auxiliary pressing cylinder 702 is fixedly connected to the auxiliary pressing plate strip 703. The auxiliary pressing plate strip 703 cooperates with the pressing plate strip 3013. Because the original plate needs to be grabbed later, the original plate will be detached from the bottom of the pressing plate strip 3013. When grabbing, in order to ensure the grabbing stability, it is necessary to start the auxiliary pressing plate strip 703 and wait until the grabbing is completed before releasing it.

[0100] In this embodiment, see Figure 9The original plate grasping assembly 8 shown has the original plate transition main body 801 as the core load-bearing structure. Original plate transition sheave wheels 802 are rotatably installed at both ends thereof. An original plate transition tension belt 803 is tensioned between the two groups of original plate transition sheave wheels 802. An original plate driven sheave wheel 804 is arranged beside one of the original plate transition sheave wheels 802. The corresponding original plate transition motor 805 is installed on one side. An original plate driving sheave wheel 806 on the rotating shaft of the original plate transition motor 805 is connected to the original plate driven sheave wheel 804 through an original plate driving belt 807. On both sides of the original plate transition belt 803, tracks 808 are provided on the original plate transition main body 801. A plurality of sets of sliders 809 adapted thereto are arranged on the tracks. These sliders 809 jointly support the original plate transition bottom plate 8010, and the original plate transition bottom plate 8010 is fixedly connected to the original plate transition belt 803. Lifting columns 8011 are vertically distributed above the original plate transition bottom plate 8010. An original plate transition lifting plate 8012 is slidably sleeved on the column body, and lifting control is realized through an original plate transition lifting air cylinder 8013. One end of the telescopic rod of the original plate transition lifting air cylinder 8013 is fixed to the original plate transition bottom plate 8010, and the other end is connected to the lifting plate. Through precise pneumatic control, the height of the original plate transition lifting plate 8012 can be flexibly adjusted according to production requirements to adapt to the grasping operation;

[0101] Three groups of original plate grasping mechanisms 8014 are integrated on the original plate transition lifting air cylinder 8013. Each group of original plate grasping mechanisms 8014 includes two groups of grasping adjustment air cylinders 80141 arranged in opposite directions. A grasping guide slider 80142 is provided beside each grasping adjustment air cylinder 80141. A grasping adjustment arm 80143 is slidably installed inside. The telescopic rod of the grasping adjustment air cylinder 80141 is fixedly connected to the end of the grasping adjustment arm 80143. When the grasping adjustment air cylinder 80141 works, the telescopic movement of the grasping adjustment arm 80143 can be accurately controlled. Cooperating with the two groups of grasping heads 80144 at the end, the grasping and releasing actions of the original plate are completed.

[0102] In this embodiment, refer to Figures 10 - 11There are two sets of the shown folding and shaping components 9, forming a dual working space. The component is based on the shaping base plate 901, and a folding table 902 is erected above. Two sets of bottom support members 903 are symmetrically arranged on the folding table 902 for supporting the bottom of the original plate to be processed. A number of sets of first stamping columns 905 are installed at the bottom of the finished product table 904 between the two. The first stamping columns 905 are sleeved with return springs 906, which can provide buffering and rebound support during the stamping process, avoid damaging the material of the original plate due to excessive pressure, and at the same time have a reset function. Flanging mechanisms 907 are equipped at both ends of the shaping base plate 901, and folding angle mechanisms 908 are correspondingly arranged at the four corners of the folding table 902 to form an all-round bending and forming system. At the same time, a number of sets of second stamping columns 909 are vertically distributed on the base plate. A stamping plate 9010 is slidably assembled between the second stamping columns 909 and is fixed at the top by a stamping support plate 9011. It is driven by a stamping cylinder 9012 to achieve precise stamping and shaping of the original plate. In addition, an alignment table mechanism 9013 is added beside one of the flanging mechanisms 907 to ensure that the original plate is in an accurate initial position before folding;

[0103] The flanging mechanism 907 uses the flanging cylinder 9071 as the power source. The cylinder body of the flanging cylinder 9071 fixes the flanging slider 9072, and the flanging arm 9073 is slidably connected inside and is rigidly connected to the telescopic rod of the flanging cylinder 9071. When the flanging cylinder 9071 is started, the flanging arm 9073 drives the end flanging head 9074 to translate along the preset track, applying pressure to the edge of the original plate to complete the straight flanging process, and the flanging angle and strength can be flexibly adjusted according to the specifications of the lunch box;

[0104] The folding angle mechanism 908 relies on the folding angle track 9081 to construct a motion guiding system. The folding angle slider 9082 on the track is driven by the folding angle cylinder 9083 to expand and contract. The folding angle member 9084 installed on the folding angle slider 9082 has a curved surface design and is precisely adapted to the contour of the corner of the lunch box. By pushing the folding angle slider 9082 to slide along the folding angle track 9081 by the folding angle cylinder 9083, the synchronous bending of the four corners of the original plate is realized, ensuring that the edges and corners of the box body are regular and the angles are consistent;

[0105] The alignment table mechanism 9013 is based on the alignment base plate 90131, and a rotatable synchronous disk 90132 is arranged below. An arc-shaped synchronous groove 90133 is opened on the disk. Four sets of alignment tracks 90134 are distributed on the surface of the base plate. The alignment sliders 90135 on them are connected to the alignment plate 90136. The synchronous shaft 90137 on the alignment plate 90136 is embedded in the synchronous groove 90133. When the synchronous cylinder 90138 drives the synchronous disk 90132 to rotate through the synchronous driving member 90139, the synchronous groove 90133 drives the synchronous shaft 90137, so that the four sets of alignment plates 90136 move synchronously along the tracks, accurately positioning the original plate from four directions, ensuring that the original plate is in a strict central position before folding, and providing a high-precision reference for the subsequent forming process.

[0106] In this embodiment, refer to Figure 12 the finished product placement component 10 shown in the figure. This component uses the finished product support side plate 1001 as the support framework. A finished product adjustment track 1002 is provided on the side wall of the finished product support side plate 1001, and a finished product adjustment slider 1003 adapted to it is provided on the finished product adjustment track 1002. A finished product adjustment cylinder 1004 is installed below the finished product adjustment track 1002 as a power element. The finished product adjustment cylinder 1004 is firmly connected to the finished product adjustment slider 1003 through a fixing plate 1005. When the finished product adjustment cylinder 1004 works, it can accurately control the sliding of the finished product adjustment slider 1003 along the finished product adjustment track 1002, thereby driving the finished product placement table 1006 fixed on the fixing plate 1005 to adjust its position. The finished product suction heads 1007 evenly distributed on the surface of the finished product placement table 1006 stably suck the bottommost lunch box finished product after folding and shaping. The subsequent lunch box finished products only need to be placed and embedded in the lower lunch box finished product in sequence.

[0107] To prevent the finished product lunch boxes from slipping during the stacking process, a finished product anti - detachment mechanism 1008 is specifically provided on the secondary frame 2 above the finished product placement table 1006. This mechanism uses the anti - detachment support bottom plate 10081 as the base, and an anti - detachment support arm 10082 is vertically installed on the bottom plate. The end of the arm is rotatably connected to a latching plate 10083 through a rotating shaft. When the finished product suction head 1007 places the lunch box on the finished product placement table 1006 for stacking, the latching plate 10083 can always maintain the restraint on the upper - layer lunch box, effectively preventing the lunch box from collapsing or slipping due to unstable stacking when the finished product suction head 1007 detaches, and ensuring the safety and regularity during the storage of the finished product.

[0108] A production method of a wooden lunch box production device includes the following operating steps:

[0109] S01: Original board placement and transportation:

[0110] Stack the wooden original boards neatly on the original board placement table 401. Adjust the position of the clamping plate member 403 through the adjusting bolt 402, and use the carding wheel 405 to limit and fix the edge of the original board. The feeding cylinder 4010 drives the feeding driving member 4011 to drive the feeding shaft 407 to rotate, so that the suction head 409 on the feeding arm 408 sucks the lowermost original board on the original board placement table 401 and places it on the conveyor belt 305. The conveying motor 308 is started, and drives the conveying shaft 303 to rotate through the conveying sprocket 309, the conveying drive belt 3010 and the driven sprocket 307, so that the conveyor belt 305 operates to convey the original board. During the conveying process, the edge - pressing cylinder 4013 first drives the edge - pressing extension arm 4014 to make the edge - pressing strip 4015 act on the edge of the original board. Secondly, after further conveying, the gap between the rear - pressing strip 3013 and the conveying main body 301 clamps the original board, and the extension anti - warping arm 30122 presses on the upper part of the original board through the action of the torsion spring to prevent the original board from warping, ensuring the stable conveyance of the original board;

[0111] S02: Glue dispensing and spreading:

[0112] The original plate moves to the position above the glue dispensing table 5011 along with the conveyor belt 305. The glue dispensing cylinder 5013 pushes the glue dispensing plate 5012 to slide. By adjusting the positions of the glue dispensing arm 5014 and the glue head support arm 5015 through the kidney-shaped holes, the glue dispensing head 5016 is aligned with the position on the original plate where glue needs to be dispensed, and the glue dispensing operation is carried out. After the glue dispensing is completed, the original plate continues to move to the position above the spreading table 5021. The spreading cylinder 5022 drives the spreading plate 5023 to move along the guide posts 5024. By adjusting the positions of the spreading arm 5025 and the spreading head 5026 through the kidney-shaped holes, the dot-applied glue is spread evenly so that the glue is evenly distributed on the original plate;

Through the magazine driving shaft 6027 and the magazine driving bevel gears 6026, the magazine driven bevel gear 6025 rotates, thereby driving the magazine driving gear disc 6022 and the magazine driving chain 6023 to operate. The original plate supporting plate 6024 moves along with the chain, transporting the original plate in the magazine frame 601 upward. During this process, the snake neck tube 605 blows out air to dehumidify the original plate on the original plate supporting plate 6024. When the original plate is transported to the middle of the magazine frame 601, the alignment cylinder 606 extends to calibrate the position of the original plate. When the original plate enters the second group of magazine mechanisms 602, the original plate will flip back to the side with the glue facing up. The second material returning cylinder 607 extends, driving the second material returning arm 608 to push the original plate to the second group of magazine mechanisms 602 after calibration;

[0115] S04: Auxiliary pressing:

[0116] After the original plate reaches the auxiliary pressing table 701, the auxiliary pressing cylinder 702 drives the auxiliary pressing strip 703 to move downward, cooperating with the pressing strip 3013 of the conveying component 3 to press the original plate, facilitating the subsequent grasping operation;

[0117] S05: Grasping and transferring the original plate

[0118] The original plate transition motor 805 starts, drives the original plate driving sheave 806, the original plate driving belt 807 and the original plate driven sheave 804 to drive the original plate transition sheave 802 to rotate, makes the original plate transition belt 803 operate, the original plate transition lifting cylinder 8013 contracts, lowers the original plate transition lifting plate 8012, positions the original plate conveyed by the alignment main body frame 1, the gripping adjustment cylinder 80141 drives the gripping adjustment arm 80143 to slide through the gripping guide slider 80142, adjusts the distance between the two groups of gripping heads 80144, after aligning with the center of the original plate, the gripping heads 80144 clamp the original plate, and then start the original plate transition lifting cylinder 8013 to lift the gripped original plate, the original plate transition belt 803 operates, and transfers the gripped original plate to the folding and shaping assembly 9 of the secondary body frame 2;

[0119] S06: Folding and shaping:

[0120] The synchronous cylinder 90138 of the alignment table mechanism 9013 drives the synchronous disk 90132 to rotate, drives the alignment plate 90136 to move along the alignment track 90134 through the synchronous groove 90133 and the synchronous shaft 90137, aligns and positions the original plate, the original plate is transferred to the folding table 902 above the shaping bottom plate 901, the bottom support member 903 supports the bottom of the original plate, the hemming cylinder 9071 drives the hemming arm 9073 to slide through the hemming slider 9072, so that the hemming head 9074 folds the edge of the original plate, the folding angle cylinder 9083 drives the folding angle slider 9082 to slide along the folding angle track 9081, and the folding angle member 9084 performs folding angle processing on the four corners of the original plate, the stamping cylinder 9012 drives the stamping plate 9010 to move downward along the second stamping column 909, and performs stamping and shaping on the folded original plate to form a preliminary shape of the wooden lunch box, and the return spring 906 resets the finished product table 904 after stamping is completed;

[0121] S07: Finished product placement and anti - detachment:

[0122] The finished product adjustment cylinder 1004 drives the finished product adjustment slider 1003 to move along the finished product adjustment track 1002, adjusts the position of the finished product placement table 1006 through the fixed plate 1005, so that it receives the folded and shaped lunch box, the finished product suction head 1007 sucks the shaped lunch box and places it on the finished product placement table 1006, the overlapping plate 10083 at the end of the anti - detachment support arm 10082 rotates above the finished product placement table 1006 to limit the edge of the uppermost lunch box, preventing the lunch box from falling off during successive placements, and completing the safe placement of the finished product.

Adjust the position of the clamping plate member (403) through the adjusting bolt (402). Use the material clamping wheel (405) to limit and fix the edge of the original board. The feeding cylinder (4010) drives the feeding driving member (4011), drives the feeding shaft (407) to rotate, so that the suction head (409) on the feeding arm (408) sucks the bottom - most original board on the original board placing table (401) and places it on the conveyor belt (305). The conveying motor (308) starts, and drives the conveying shaft (303) to rotate through the conveying grooved wheel (309), the conveying driving belt (3010) and the driven grooved wheel (307), so that the conveyor belt (305) operates to convey the original board. During the conveying process, the edge - pressing cylinder (4013) first drives the edge - pressing extension arm (4014) to drive the edge - pressing strip (4015) to act on the edge of the original board. Secondly, after further conveying, the gap between the pressing strip (3013) and the conveying main body (301) clamps the original board. The extension anti - warping arm (30122) presses on the upper side of the original board through the action of the torsion spring to prevent the original board from warping and ensure the stable conveying of the original board. S02: Glue - dotting and spreading: The original plate moves to above the dispensing table (5011) along with the conveyor belt (305). The dispensing cylinder (5013) pushes the dispensing plate (5012) to slide. The positions of the dispensing arm (5014) and the glue head support arm (5015) are adjusted through the kidney-shaped holes, so that the dispensing head (5016) is aligned with the position on the original plate where glue needs to be dispensed, and the dispensing operation is carried out. After the dispensing is completed, the original plate continues to move to above the smoothing table (5021). The smoothing cylinder (5022) drives the smoothing plate (5023) to move along the guide post (5024). The positions of the smoothing arm (5025) and the smoothing head (5026) are adjusted through the kidney-shaped holes to smooth the dispensed glue, so that the glue is evenly distributed on the original plate; S03: Hopper Feeding and Alignment: The first material returning cylinder (5027) extends, driving the first material returning arm (5028) to push the smoothed original plate into the first group of the hopper mechanisms (602). The hopper driving motor (604) drives the turnover box (603) to rotate. Through the hopper driving shaft (6027) and the hopper driving bevel gear (6026), the hopper driven bevel gear (6025) rotates, thereby driving the hopper driving gear disc (6022) and the hopper driving chain (6023) to operate. The original plate supporting plate (6024) moves along with the chain to convey the original plate in the hopper frame (601) upward. During the process, the gooseneck tube (605) blows out air to dehumidify the original plate on the original plate supporting plate (6024). When the original plate is conveyed to the middle of the hopper frame (601), the alignment cylinder (606) extends to calibrate the position of the original plate. When the original plate enters the second group of hopper mechanisms (602), the original plate will flip back to the side with the glue facing up. The second material returning cylinder (607) extends, driving the second material returning arm (608) to push the original plate to the second group of the calibrated original plate into the hopper mechanism (602); S04: Auxiliary Pressing: After the original plate reaches the auxiliary pressing table (701), the auxiliary pressing cylinder (702) drives the auxiliary pressing strip (703) to move downward, cooperating with the pressing strip (3013) of the conveying assembly (3) to press the original plate, facilitating the subsequent grasping operation; S05: Original Plate Grasping and Transfer The original plate transition motor (805) starts, drives the original plate driving sheave (806), the original plate driving belt (807) and the original plate driven sheave (804) to drive the original plate transition sheave (802) to rotate, so that the original plate transition belt (803) operates. The original plate transition lifting cylinder (8013) contracts to lower the original plate transition lifting plate (8012) to align with the original plate conveyed by the main body frame (1). The grasping adjustment cylinder (80141) drives the grasping adjustment arm (80143) to slide through the grasping guide slider (80142) to adjust the distance between the two groups of grasping heads (80144). After aligning with the center of the original plate, the grasping heads (80144) clamp the original plate, and then the original plate transition lifting cylinder (8013) is started to lift the grasped original plate. The original plate transition belt (803) operates to transfer the grasped original plate to the folding and shaping assembly (9) of the sub-body frame (2). S06: Folding and shaping: The synchronous cylinder (90138) of the alignment table mechanism (9013) drives the synchronous disk (90132) to rotate, and drives the alignment plate (90136) to move along the alignment track (90134) through the synchronous groove (90133) and the synchronous shaft (90137) to align and position the original plate. The original plate is transferred to the folding table (902) above the shaping bottom plate (901). The bottom support member (903) supports the bottom of the original plate. The hemming cylinder (9071) drives the hemming arm (9073) to slide through the hemming slider (9072) so that the hemming head (9074) folds the edge of the original plate. The folding angle cylinder (9083) drives the folding angle slider (9082) to slide along the folding angle track (9081), and the folding angle member (9084) performs folding angle processing on the four corners of the original plate. The stamping cylinder (9012) drives the stamping plate (9010) to move downward along the second stamping column (909) to stamp and shape the folded original plate to form a preliminary shape of the wooden lunch box. The return spring (906) resets the finished product table (904) after stamping is completed. S07: Finished product placement and anti-detachment: The finished product adjustment cylinder (1004) drives the finished product adjustment slider (1003) to move along the finished product adjustment track (1002), and adjusts the position of the finished product placement table (1006) through the fixed plate (1005) so that it receives the folded and shaped lunch box. The finished product suction head (1007) sucks the shaped lunch box and places it on the finished product placement table (1006). The edge-lapping plate (10083) at the end of the anti-detachment support arm (10082) rotates above the finished product placement table (1006) to limit the edge of the uppermost lunch box to prevent the lunch box from falling off during successive placement, thus completing the safe placement of the finished product.
