Description

Technical Field

[0001] The present invention relates to the technical field of degradable lunch boxes, and in particular to a rotary continuous environmentally friendly lunch box production device based on degradable materials. Background Art

[0002] Currently, the recycling rate for plastic bags and plastic lunch boxes in China is very low. Disposable utensils in daily life and industrial production cause severe landscape and environmental pollution. Consequently, research into biodegradable lunch boxes and tableware has gradually become a priority. In recent years, a variety of biodegradable tableware types have emerged on the market: laminated cardboard, biodegradable plastic, plant fiber, starch, and molded pulp.

[0003] Straw fiber molding technology has been increasingly widely used in food packaging, industrial cushioning packaging and other fields due to its wide source of raw materials, biodegradable products and environmentally friendly characteristics. Especially in the field of disposable tableware, straw fiber lunch boxes are gradually replacing traditional plastic lunch boxes and becoming the mainstream choice in the market.

[0004] However, the current straw fiber lunch box forming devices on the market still have some problems that need to be improved in the actual production process. In terms of production efficiency, the connection between the various processes of many devices is not smooth enough, and often requires a lot of auxiliary time to complete the process conversion, resulting in a slower overall production rhythm; from the perspective of structural complexity and energy consumption, some devices have too many drive components and transmission mechanisms in order to realize the operation of multiple processes, and lack linkage, which not only makes the structure of the equipment complicated, but also increases the manufacturing cost and maintenance difficulty of the equipment; in terms of the degree of automation, some devices still require manual intervention or auxiliary operations in key processes such as slurry dipping, injection, stamping, and demolding, which not only increases labor costs, but may also affect the quality stability of the product due to the uncertainty of human operation. Summary of the Invention

[0005] The purpose of the present invention is to provide a rotary continuous environmentally friendly lunch box production device based on biodegradable materials to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a rotary continuous environmentally friendly lunch box production device based on biodegradable materials, comprising: a bottom frame and a top frame fixed thereon, and further comprising:

[0007] The slurry dipping mechanism includes a U-shaped frame rotatably mounted on the top frame and having a sliding rod sliding therein, a driven top block fixedly mounted on one side of the sliding rod and capable of contacting the fixed top block, a slurry dipping plate fixedly mounted on the sliding rod, a slurry barrel fixedly mounted on the bottom frame, and a slurry barrel bottom plate slidably mounted in the slurry barrel;

[0008] The rotary mechanism includes a rotary plate rotatably mounted on a bottom frame and coaxially fixed with a sheave, an active dial in contact with the sheave and coaxially mounted with the U-shaped frame, a lower die fixedly mounted on the surface of the rotary plate, a lever hingedly mounted on the surface of the rotary plate, a wedge-shaped block capable of contacting the lever and fixedly connected to the top frame, and an upper die fixedly mounted at one end of the lever and capable of extending into the lower die.

[0009] When the U-shaped frame rotates and drives the driven top block on the sliding rod to contact the fixed top block, the slurry plate on the sliding rod picks up the slurry, and the rotation of the U-shaped frame drives the slurry plate to inject the slurry into the lower mold core. The rotation of the turntable drives the lever on it to contact the wedge block and make the upper mold extend into the lower mold core to press the slurry in the lower mold core.

[0010] Preferably, the sprocket mechanism includes: a U-shaped frame fixedly connected to one output end of the dual-output shaft motor, the other output end of the dual-output shaft motor fixedly connected to the first transmission wheel, a belt is sleeved on the first transmission wheel, the other end of the belt is sleeved on the second transmission wheel, and an active dial is coaxially fixedly arranged on the second transmission wheel.

[0011] Preferably, the sprocket mechanism comprises: a groove wheel coaxially fixedly provided on the rotary disk, an active dial rotatably provided on the top frame, and a radial groove on the groove wheel capable of contacting and connecting with a dial pin on the active dial.

[0012] Preferably, a drying box is fixedly provided on the base frame, and the drying box can dry the lower mold core that has completed the molding.

[0013] Preferably, an electric push rod is fixedly arranged on the base frame, and the movable rod end of the electric push rod extends into the pulp barrel and is fixedly connected to the pulp barrel bottom plate.

[0014] Preferably, a through hole is provided in the lower mold core, an electric telescopic rod is fixedly provided on the base frame, a movable rod end of the electric telescopic rod is fixedly connected to the ejector pin, and the ejector pin can extend into the through hole of the lower mold core.

[0015] Preferably, the lower mold cores are fixedly arranged on the surface of the turntable in a circumferentially equidistant installation manner, and there are six lower mold cores.

[0016] Preferably, a plurality of through holes are provided on the surface of the slurry plate, through which the adhesion between the slurry and the slurry plate can be improved.

[0017] Preferably, the electric push rod is connected via a controller, and the electric push rod gradually extends over time.

[0018] Preferably, the wedge-shaped block is fixedly connected to the top frame via a connecting rod, and one side surface of the wedge-shaped block is an inclined surface.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This device drives the sliding rod and driven top block by rotating the U-shaped frame. After the driven top block contacts the fixed top block, it is pressed downward, and the sliding rod then drives the slurry plate on it downward until the driven top block contacts the straight edge of the fixed top block and stops. The slurry plate extends into the slurry barrel to be dipped in slurry. After losing contact, the sliding rod resets, and the slurry plate is completely dipped in slurry. The U-shaped frame continues to rotate, and the slurry plate rotates above the turntable. At this time, the active dial toggles the groove wheel to rotate the turntable, moving the slurry-free lower mold core below the slurry plate. After the driven top block contacts the other fixed top block, it moves downward, and the slurry plate extends into the lower mold core to inject material. After losing contact, it resets, completing the injection. The turntable drives the lever to move. Its inclined end contacts the wedge block and moves upward (the longitudinal spring extends). The other end drives the upper mold down to perform the stamping. After losing contact, the longitudinal spring resets, the upper mold is disengaged, and the stamping is complete.

[0021] The device integrates the processes of dipping, injection, stamping, drying and demoulding into an intermittent rotating operation path through the synchronous rotation design of the U-shaped frame and the turntable. When the U-shaped frame rotates, the mechanical linkage between the driven top block and the fixed top block is used to realize the automatic lifting of the dipping plate, and the dipping and injection can be completed without additional pauses. At the same time, the grooved wheel mechanism drives the turntable to rotate intermittently to accurately realize the switching of the lower mold core station, so that each process is seamlessly connected, which greatly reduces the auxiliary time for process conversion and significantly improves production efficiency and overall production rhythm.

[0022] The device uses a single drive motor to synchronously drive the U-shaped frame, the second pulley and the active dial, and replaces the complex structure of traditional multi-drive components with mechanical linkage. For example, the lifting and lowering of the slurry plate is only achieved by the contact resistance between the driven top block and the fixed top block and the elastic force of the return spring. The stamping action is completed through the mechanical coordination of the lever and the wedge block, without the need for an additional power source, thereby simplifying the structural design. In addition, the device realizes mechanical linkage control throughout the entire process, and no manual intervention is required from slurry dipping to demolding. The slurry dipping amount, injection position, stamping pressure, etc. can be precisely controlled, which improves the degree of automation and ensures quality stability.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-7 , the present invention provides a technical solution:

[0033] like Figure 1 As shown, in order to realize the molding of straw fiber, a rotary continuous environmentally friendly lunch box production device based on biodegradable materials is proposed, comprising: a base frame 1, a top frame 101 fixedly arranged on the base frame 1, the base frame 1 is used to place the device on the ground, and the top frame 101 is located above the base frame 1, and further comprising:

[0034] An electric push rod 201 is fixedly arranged on the base frame 1, and the fixed rod end of the electric push rod 201 is fixedly connected to the base frame 1, and the movable rod end extends into the pulp barrel 203 and is fixedly connected to the lower surface of the pulp barrel bottom plate 202. The position where the electric push rod 201 extends into the pulp barrel 203 is the center of the bottom of the pulp barrel 203. A circular notch with an outer diameter slightly larger than the electric push rod 201 is provided at the center of the bottom of the pulp barrel 203. The circular notch is provided with a rubber strip along its circumference. The setting of the rubber strip can achieve a sealing effect, thereby preventing the slurry from flowing out from the gap between the circular notch and the electric push rod 201.

[0035] The pulp barrel bottom plate 202 is slidably installed in the pulp barrel 203. The position of the pulp barrel bottom plate 202 is higher than the bottom surface of the pulp barrel 203. In the initial state, the lower surface of the pulp barrel bottom plate 202 is in contact with the bottom surface of the pulp barrel 203. The outer wall of the pulp barrel bottom plate 202 is slidably connected to the pulp barrel 203. The pulp barrel bottom plate 202 can slide longitudinally along the extension direction of the pulp barrel 203. The pulp barrel 203 is fixedly set on the base frame 1. The pulp barrel 203 can hold slurry. When pouring slurry into the pulp barrel 203, the pulp barrel bottom plate 202 The upper surface of 02 is in contact with the slurry, and the electric push rod 201 is electrically connected to the controller. The controller adopts an existing PLC controller. The controller can control the electric push rod 201 to gradually extend. As the slurry in the slurry barrel 203 gradually decreases, the electric push rod 201 pushes the slurry barrel bottom plate 202 to gradually move upward in the slurry barrel 203. The slurry barrel bottom plate 202 pushes the slurry upward to ensure that the slurry plate 308 proposed below can be extended into the slurry in the slurry barrel 203 every time it descends (shown in Figure 2 ), ensure the stability of the slurry dipping plate 308.

[0036] The top frame 101 is fixedly provided on the bottom frame 1, and the top frame 101 is located above the pulp barrel 203. A dual-output shaft motor 301 is fixedly provided on the top frame 101. The lower output end of the dual-output shaft motor 301 is fixedly connected to the U-shaped frame 302 through the connecting frame 309. The dual-output shaft motor 301 can drive the U-shaped frame 302 to rotate through the connecting frame 309. The U-shaped frame 302 is inverted relative to the top frame 101, and its opening is downward. A sliding rod 303 is slidably connected to the inside of the two straight side rods of the U-shaped frame 302. The sliding rod 303 is inserted into the U-shaped frame 302, and the axes of the two sliding rods 303 are parallel. The sliding rod 303 can When the outer force on the sliding rod 303 is released, the return spring 304 will be reset due to its own characteristics, and the return spring 304 will generate a pulling force on the sliding rod 303 and drive the sliding rod 303 to move upward and return to the starting position (shown in FIG). Figure 3 ), when the sliding rod 303 moves downward or upward, it drives the slurry plate 308 mentioned below to extend into the slurry barrel 203 and drives the slurry plate 308 to separate from the slurry in the slurry barrel 203.

[0037] One side of each sliding rod 303 is fixedly connected to a driven top block 305, and the shape of the driven top block 305 is approximately trapezoidal, and an inclined surface is provided on both sides of the driven top block 305, which is an arc with a smaller curvature. The direction in which the driven top block 305 is installed is: the short side surface is higher than the long side surface; the driven top block 305 can move with the rotation of the U-shaped frame 302, and a top block frame 306 is fixedly provided on the base frame 1. The top block frame 306 is U-shaped, and the spacing between the two straight side rods of the top block frame 306 is smaller than the spacing between the two straight side rods of the U-shaped frame 302. Therefore, the top block frame 306 is nested and installed between the two straight side rods on the U-shaped frame 302.

[0038] The connecting end of the top block frame 306 and the top frame 101 passes through the U-shaped frame 302 and is fixedly connected to the top frame 101. The top block frame 306 is rotatably connected to the U-shaped frame 302, and the U-shaped frame 302 can rotate relative to the top block frame 306. A fixed top block 307 is fixed at both ends of the top block frame 306. The two fixed top blocks 307 are symmetrically arranged. The position of the fixed top block 307 is fixed. The fixed top block 307 corresponds to the driven top block 305, and an arc-shaped inclined surface corresponding to the driven top block 305 is arranged at both ends. The driven top block 305 and the fixed top block 307 have the same shape and are installed in opposite directions (shown in Figure 5), when the driven top block 305 moves and rotates half a circle around the rotation point of the U-shaped frame 302, one side surface of it first contacts the fixed top block 307. After contact, the driven top block 305 will be subjected to the resistance from the fixed top block 307. The driven top block 305 continues to rotate and gradually moves downward under the action of the fixed top block 307. The driven top block 305 is fixedly connected to the sliding rod 303, so the sliding rod 303 will move downward accordingly. As the U-shaped frame 302 drives the sliding rod 303 to rotate and then drives the driven top block 305 to move gradually, the driven top block 305 continues to be pushed by the fixed top block 307, the driven top block 305 continues to move downward, the sliding rod 303 continues to move downward, and the reset The spring 304 stretches until the inclined surface of one side of the driven top block 305 is disconnected from the inclined surface of one side of the fixed top block 307, and the straight edges of the two are in contact. At this time, the driven top block 305 is no longer subject to resistance from the inclined surface of the fixed top block 307, and the driven top block 305 stops moving downward, and the sliding rod 303 stops moving downward accordingly. The U-shaped frame 302 continues to rotate, and the driven top block 305 continues to rotate until the driven top block 305 is disengaged from the fixed top block 307. At this time, the driven top block 305 loses the limiting force from the fixed top block 307, and the sliding rod 303 is reset under the action of the reset spring 304, thereby realizing that the slurry plate 308 gradually extends into the slurry barrel 203 to pick up the slurry and then automatically rises.

[0039] The end of the sliding rod 303 away from the U-shaped frame 302 is fixedly connected to the slurry plate 308, and the slurry plate 308 can move with the movement of the sliding rod 303. When the sliding rod 303 moves downward, the slurry plate 308 on it will gradually extend into the slurry barrel 203. Since the slurry in the slurry barrel 203 is viscous and through holes are provided on the surface of the slurry plate 308, the through holes increase the contact area between the slurry plate 308 and the slurry. The contact area between the slurry plate 308 and the slurry is greatly increased, which can provide more adsorption sites, thereby enhancing the adsorption effect. Therefore, when the slurry plate 308 gradually extends into the slurry barrel 203, the slurry will stick to the surface of the slurry plate 308. When the driven top block 305 loses its limiting force and the sliding rod 303 returns upward under the action of the return spring 304, the sliding rod 303 drives the slurry plate 308 to move upward, and the slurry plate 308 is separated from the slurry in the slurry barrel 203, completing the work of the slurry plate 308 to pick up the slurry.

[0040] A rotary disk 408 is provided on one side of the pulp barrel 203, and the rotary disk 408 is rotatably mounted on the base frame 1. The upper surface of the rotary disk 408 is coaxially fixedly connected to one end of the longitudinal rod, and the other end of the longitudinal rod is coaxially fixedly connected to the groove wheel 407. The radial groove on the groove wheel 407 can be in contact with the toggle pin on the active dial 404. The active dial 404 is rotatably set on the top frame 101 through the connecting rod 405. One end of the connecting rod 405 is fixedly connected to the top frame 101, and the active dial 404 can drive the groove wheel 407 to rotate. The intermittent motion is carried out, thereby driving the turntable 408 to realize intermittent motion. The intermittent rotation of the turntable 408 can realize the intermittent rotation of the lower mold core 413 proposed below. The second transmission wheel 403 is coaxially fixed on the active dial 404, and a belt 402 is sleeved on the second transmission wheel 403. The other end of the belt 402 is sleeved on the first transmission wheel 401. The first transmission wheel 401 is fixedly set on the upper output shaft of the dual-output shaft motor 301, and the first transmission wheel 401 is located above the dual-output shaft motor 301.

[0041] The dual-output shaft motor 301 drives the first transmission wheel 401 to rotate while driving the U-shaped frame 302 to rotate. The first transmission wheel 401 drives the second transmission wheel 403 to rotate through the belt 402, and then drives the active dial 404 to rotate. When the toggle pin on the active dial 404 contacts the radial groove on the groove wheel 407, the active dial 404 drives the groove wheel 407 to rotate, and the turntable 408 rotates. When the toggle pin on the active dial 404 loses contact with the radial groove on the groove wheel 407, and the outer concave locking arc on the active dial 404 contacts the inner concave locking arc on the groove wheel 407, the groove wheel 407 stops rotating and is locked, and no free rotation occurs, thereby realizing intermittent rotation of the turntable 408. The dual-output shaft motor 301 realizes intermittent rotation of the turntable 408 while driving the U-shaped frame 302 to rotate continuously.

[0042] When the U-shaped frame 302 rotates and drives the slurry-soaked slurry plate 308 to rotate above the rotary disk 408, the toggle pin on the active dial 404 loses contact with the radial groove on the groove wheel 407, and the outer concave locking arc on the active dial 404 contacts the inner concave locking arc on the groove wheel 407, and the rotary disk 408 stops rotating. At this time, the slurry plate 308 extends into the lower mold core 413 on the rotary disk 408 under the action of the driven top block 305 and the fixed top block 307. The U-shaped frame 302 continues to rotate, the driven top block 305 and the fixed top block 307 are disengaged, and the slurry plate 308 is released from the lower mold core 413 under the action of the return spring 304. 13 extends out to complete the grouting operation of the lower mold core 413. Subsequently, the driving pin on the active dial 404 contacts the radial groove on the groove wheel 407. The active dial 404 drives the groove wheel 407 to rotate, and the turntable 408 rotates. The turntable 408 continues to rotate and stops after moving a distance. During the rotation of the turntable 408, the upper mold 411 mentioned below is used for the molding operation. After the molding operation is completed, the turntable 408 continues to perform subsequent drying and demoulding operations intermittently. The intermittent rotation of the turntable 408 can realize the unloading, molding, drying and demoulding of the slurry in the lower mold core 413.

[0043] Six lower mold cores 413 are arranged in an equidistant manner along the circumference of the upper surface of the turntable 408. The lower mold cores 413 can move as the turntable 408 rotates. Four through holes are provided on the lower surface of each lower mold core 413. The through holes can allow the ejector pin 602 mentioned below to extend into. Six brackets 409 are arranged in an equidistant manner along the circumference of the upper surface of the turntable 408. The circumferential radius formed by the six brackets 409 is smaller than the circumferential radius formed by the six lower mold cores 413. The installation position of each bracket 409 corresponds to the position of each lower mold core 413. Each lower mold core 413 corresponds to a bracket 409, and the two are in the same radial direction of the turntable 408. A lever 410 is hinged on each bracket 409. The lever 410 0 is fixedly connected to the upper mold 411. In the initial state, the upper mold 411 is located obliquely above the lower mold core 413. The upper mold 411 will not affect the injection operation of the lower mold core 413. The upper mold 411 can be extended into the lower mold core 413 and perform the molding operation under the drive of the lever 410. The other end of the lever 410 is provided with an inclined surface, and the surface of the end away from the upper mold 411 is fixedly connected to one end of the longitudinal spring 414. The other end of the longitudinal spring 414 is fixedly connected to the surface of the rotary disk 408. One end of the longitudinal spring 414 is perpendicular to the axis of the rotary disk 408. A mounting plate 415 is fixed to one end of the connecting rod 405. The mounting position of the connecting rod 405 and the mounting plate 415 is a non-center position on the upper surface of the mounting plate 415. The disk 415 is coaxially arranged with the rotary disk 408. The lower surface of the mounting disk 415 is rotatably connected to the upper surface of the rotary disk 408. The position of the mounting disk 415 relative to the rotary disk 408 is relatively fixed. A wedge block 412 is fixedly arranged on the upper surface of the mounting disk 415. The wedge block 412 is located above the rotary disk 408. The upper surface of the wedge block 412 is set as an inclined surface. The position of the wedge block 412 is fixed relative to the rotary disk 408. When the rotary disk 408 rotates and drives the lever 410 thereon to move synchronously, the inclined end of the lever 410 contacts the upper surface of the wedge block 412. The end is pushed by the wedge block 412 and moves upward. The longitudinal spring 414 is stretched under the force. At this time, the other end of the lever 410 The upper die 411 on the upper die 413 is gradually extended into the lower die core 413. As the lever 410 continues to descend, the upper die 411 presses the slurry in the lower die core 413 to form the slurry in the lower die core 413. The rotary disk 408 stops rotating. At this time, the upper die 411 is still in the lower die core 413. The slurry in the lower die core 413 is continuously subjected to the pressure of the upper die 411. When the rotary disk 408 continues to rotate, the inclined end of the lever 410 loses contact with the wedge block 412, and the longitudinal spring 414 is forced to be retracted and reset. The longitudinal spring 414 pulls the lever 410 to rotate around its connection point with the rotary disk 408 and return to the starting position. At this time, the upper die 411 is separated from the lower die core 413 (shown in Figure 6 ).

[0044] A drying box 501 is set on the base frame 1. The drying box 501 adopts the existing drying technology. A notch is set on one side of the drying box 501. The intermittent rotation of the turntable 408 can drive the lower mold core 413 thereon to rotate into the drying box 501. When the lower mold core 413 that has completed the die pressing is rotated into the drying box 501, the turntable 408 stops rotating, and the drying box 501 dries the lunch box in the stamped lower mold core 413, thereby increasing the speed of lunch box molding and facilitating the subsequent removal of the lunch box.

[0045] After the drying box 501 has dried the lunch box in the stamped lower mold core 413, the turntable 408 continues to rotate for a distance and stops. A ejector pin 602 is provided under the turntable 408. The ejector pin 602 is fixedly connected to the fixed rod of the electric telescopic rod 601. The electric telescopic rod 601 is fixedly provided on the base frame 1. The ejector pin 602 corresponds to the through hole in the lower mold core 413. Under the action of the electric telescopic rod 601, the ejector pin 602 can be extended into the through hole and eject the dried lunch box in the lower mold core 413 (shown in FIG. Figure 7 ).

[0046] Working principle:

[0047] First, turn on the switch of the dual-output shaft motor 301, the dual-output shaft motor 301 can drive the U-shaped frame 302 to rotate, and the U-shaped frame 302 drives the sliding rod 303 thereon to rotate, and the driven top block 305 can move with the rotation of the U-shaped frame 302. When the driven top block 305 moves, one side surface of it contacts the fixed top block 307. After contact, the driven top block 305 is subjected to resistance from the fixed top block 307 and moves downward. The driven top block 305 is fixedly connected to the sliding rod 303, so the sliding rod 303 will move downward accordingly. As the driven top block 305 gradually moves, it continues to be pushed by the fixed top block 307, the driven top block 305 continues to move downward, the sliding rod 303 continues to move downward, and the return spring 304 extends until it is released. The inclined surface of one side of the movable top block 305 is disconnected from the inclined surface of one side of the fixed top block 307, and the straight edges of the two are in contact. At this time, the driven top block 305 stops moving downward, and the sliding rod 303 stops moving downward accordingly. At this time, the slurry plate 308 extends into the slurry barrel 203, the U-shaped frame 302 continues to rotate, and the driven top block 305 continues to move. The slurry will stick to the surface of the slurry plate 308 until the driven top block 305 is separated from the fixed top block 307. At this time, the driven top block 305 loses the restricting force from the fixed top block 307, and the sliding rod 303 is reset under the action of the reset spring 304. The sliding rod 303 drives the slurry plate 308 to move upward, and the slurry plate 308 is separated from the slurry in the slurry barrel 203, completing the work of the slurry plate 308 to pick up the slurry.

[0048] At this time, the U-shaped frame 302 continues to rotate, and the slurry-soaked dipping plate 308 gradually rotates to the top of the rotary disk 408. The dual-output shaft motor 301 drives the first transmission wheel 401 to rotate while driving the U-shaped frame 302 to rotate. The first transmission wheel 401 drives the second transmission wheel 403 to rotate through the belt 402, and then drives the active dial 404 to rotate. When the dial pin on the active dial 404 contacts the radial groove on the groove wheel 407, the active dial 404 drives the groove wheel 407 to rotate, and the rotary disk 408 rotates, driving the slurry-free lower mold core 413 thereon to move to the bottom of the slurry-soaked dipping plate 308. At this time, the rotary disk 408 stops rotating, and the driven top block 305 moves, and its one side surface contacts another fixed top block 307 on the top block frame 306. After contact, the driven top block 305 will be subjected to the resistance from the fixed top block 307 and move downward. After the cam 308 is in the process of being pressed down, the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam 308 is in the process of being pressed down, and the cam

[0049] When the turntable 408 resumes rotation, and when the turntable 408 rotates and drives the lever 410 on it to move synchronously, the inclined end of the lever 410 contacts the upper surface of the wedge block 412, and the end is pushed by the wedge block 412 and moves upward, and the longitudinal spring 414 extends. At this time, the other end of the lever 410 drops accordingly, and the upper mold 411 on it gradually extends into the lower mold core 413. As the lever 410 continues to drop, the upper mold 411 punches the slurry in the lower mold core 413, forming the slurry in the lower mold core 413. As the turntable 408 continues to rotate, the inclined end of the lever 410 loses contact with the wedge block 412, and the longitudinal spring 414 is relieved and reset and compressed. The longitudinal spring 414 pulls the lever 410 to rotate around its connection point with the turntable 408 and return to the starting position. At this time, the upper mold 411 is separated from the lower mold core 413, completing the stamping of the lunch box in the lower mold core 413.

[0050] The rotation of the turntable 408 can drive the lower die core 413 thereon to rotate into the drying box 501. The drying box 501 dries the lunch boxes in the stamped lower die core 413, thereby increasing the speed of forming the lunch boxes and facilitating the subsequent removal of the lunch boxes.

[0051] The rotation of the turntable 408 drives the dried lower mold core 413 to continue moving until it moves above the ejector pin 602. The ejector pin 602 can extend into the through hole under the action of the electric telescopic rod 601 and eject the dried lunch box in the lower mold core 413, completing the demoulding of the lunch box.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
